  • DETAILED DESCRIPTION
  • Hereinafter, a first embodiment of the invention will be described with reference to the accompanying drawings. FIG. 1 schematically shows an external appearance of a recording apparatus 100 which will be described in the first embodiment, and a cartridge 101 to which the recording apparatus 100 is detachably attached. For examples the cartridge 101 is installed in a display apparatus such as a television set. FIG. 2 schematically shows an exemplary exploded view of the recording apparatus 100.
  • The recording apparatus 100 has a parallelepiped shape as shown in FIG. 1. As shown in FIG. 2, the recording apparatus 100 mainly includes an upper housing 1, a lower housing 2, an HDD unit 3, shock-absorbing members 4, a metal plate 5, and a conductive member 6.
  • The upper housing 1 and the lower housing 2 constitute a case for accommodating and protecting the HDD unit 3, the shock-absorbing members 4, the metal plate 5, and the conductive member 6, and are made of a material such as plastic. The upper housing 1 is a housing for covering a face on the side where a top cover 10 of the HDD unit 3 is placed (see FIG. 3), and preferably provided with a plurality of slits 1 a. Heat generated in the HDD unit 3 during the operation of the recording apparatus 100 is dissipated from the side of the top cover 10 to the outside, so that the heat radiating property is improved.
  • The lower housing 2 is a housing for covering side faces of the HDD unit 3 and a face on the side where a base chassis 11 is disposed (see FIG. 3). In one of the shorter side faces of the lower housing 2, an opening 2 a which is to be connected to a connector of an external apparatus (for example, a connector 102 of the cartridge 101 shown in FIG. 1) is formed. Specifically, a connector 14 (see FIG. 3) of the HDD unit 3 is exposed to the outside through the opening 2 a, so that the connector 14 is connected to the connector of the external apparatus via the opening 2 a. After the HDD unit 3, the shock-absorbing member 3, and the like are accommodated, the upper housing 1 and the lower housing 2 are integrated with each other as shown in FIG. 1 by means of, for example, screwing.
  • The HDD unit 3 is a unit for performing and controlling the recording/reproduction of data. As shown in FIGS. 3A and 3B, the HDD unit includes the top cover 10 in which the surface is covered with a metal material such as aluminum die cast, and the base chassis 11 which is similarly formed by a metal material such as aluminum die cast. In the HDD unit 3, for example, a plurality of magnetic disks 12 of about 1 to 3.5 inches, a plurality of heads for reading and writing data from and to the magnetic disks 12, and a driving portion (not shown) such as a motor for rotationally driving the magnetic disks 12 are placed in the inside on the side of the top cover 10.
  • On the other hand, on the side of the base chassis 11, a circuit board 13 is placed on which a number of semiconductor integrated circuits (control circuits) for controlling recording/reproduction of the HDD unit 3 are disposed. On the other shorter side face of the base chassis 11, the connector 14 (for example, an SATA connector) is disposed. The connector is electrically connected to the semiconductor integrated circuits of the circuit board 13, and functions as an interface portion for performing data transfer between the external apparatus and the HDD unit 3. The connector 14 described herein is a connector as a portion exposed to the outside. In the actual usage, a conversion connector (for example, an iVDR connector) is mounted on the connector 14, and the conversion connector is sometimes used as the external interface. The top cover 10 and the base chassis 11 can be considered as a housing for covering and accommodating the recording medium unit body (such as the magnetic disks 12).
  • The shock-absorbing members 4 are constituted by including an elastic and flexible material such as natural rubber or a synthetic resin. The shock-absorbing members include holding portions 4 a for clamping and fixing both the longer side faces of the HDD unit 3, at positions corresponding to respective edge portions of the HDD unit 3. The thus configured shock-absorbing members 4 clampingly hold the side faces of the HOD unit 3, so that the HDD unit 3 can be easily fixed in the housing, and the HDD unit 3 is prevented from being directly in contact with the upper housing 1 and the lower housing 2. Namely, the shock-absorbing members 4 have a principal function of reducing an impact on the housing from the outside to prevent the impact from being transmitted to the HDD unit 3.
  • As shown in FIGS. 2 and 4, the metal plate 5 configured by: a vertical plate 5 a which is perpendicular to the principal surface of the HOD unit 3; a horizontal plate 5 b which is continuous to an upper portion of the vertical plate 5 a, and which is bent horizontally (i.e., in parallel to the principal surface of the HOD unit 3); and a horizontal plate 5 c which is continuous to a lower portion of the vertical plate 5 a, and which is bent horizontally. FIG. 4 is a front view of the metal plate 5.
  • In the vertical plate 5 a, in order to enable the connection between the connector of the external apparatus and the HDD unit 3, as shown in FIG. 4, an opening 20 is formed at a position corresponding to the connector 14. The vertical plate 2 a is formed so as to cover substantially the entire of the opening 2 a of the lower housing, except the region corresponding to the connector 14. Accordingly, the connector 14 of the HDD unit 3 is exposed to the outside through the opening 2 a and the opening 20. Thus, the connector 14 is connected to the connector of the external apparatus through the openings 2 a, 20.
  • The vertical plate 5 a and the horizontal plates 5 b, 5 c constitute a U-like shape when they are viewed from the lateral side. Therefore, the horizontal plates 5 b, 5 c clamp another member (the shock-absorbing members 4 in the embodiment) in the vertical direction, whereby the metal plate 5 can be prevented from being displaced in the housing in the vertical direction.
  • On the both ends of the vertical plate 5 a, claw plates 5 d which stand substantially perpendicularly to the vertical plate 5 a are formed. Therefore, another member (for example, the holding portions 4 a of the shock-absorbing members 4) is clamped by the claw plates 5 d, or the claw plates 5 d are fitted into fitting portions which are not shown, and which are disposed in the housing, thereby preventing the metal plate 5 from being displaced in the horizontal direction.
  • The conductive member 6 is a conductive member which is in contact with the metal plate 5 and the metal face of the HDD unit 3 (the top cover 10 in the embodiment), thereby electrically connecting them via the conductive member 6. Preferably, the conductive member includes a highly conductive material. An example of the conductive member 6 is a copper foil tape having a thickness of about 0.035 mm and containing copper. The conductive member is preferably flexible, because, when an impact is applied to the metal plate 5 from the outside, the impact is not transmitted to the HDD unit 3 via the conductive member 6. In the conductive member 6, for example, an adhesive material is applied to at least a part of one of the faces, and is used while the face onto which the adhesive material is applied is bonded to the metal plate 5 and the top cover portion 10. In the case where a tape-shaped member is used as the conductive member 6, it is preferred that the conductive tape is subjected to embossing, in order to ensure a larger contact area and to attain stable conductivity. A larger contact area is preferred in view of the heat radiation through the top cover 10.
  • Next, a sectional structure of the recording apparatus 100 will be described with reference to FIGS. 5A and 5B. FIG. 5A is a sectional view taken along the line A-A in FIG. 1, and FIG. 5B is a sectional view taken along the line B-B in FIG. 1.
  • As shown in FIG. 5A, the recording apparatus 100 of the embodiment comprises the metal plate 5 having the opening 20 so that the connector 14 is exposed to the outside, and the metal plate 5 and the metal face (the top cover 10) of the recording medium unit (the HDD unit 3) are electrically connected to each other through the conductive member 6.
  • Even when static electricity is generated in the vicinity of the connector 14 by, for example, bringing a finger of a human being closer to the connector, therefore, the static electricity is discharged to the metal face of the recording medium unit through the metal plate 5 and the conductive member 6. As described above, when static electricity is generated, the static electricity is not discharged to the internal circuit of the HDD unit 3 through the connector 14, because the surface of the top cover 10 has a lower resistive component as compared with the internal circuit in the circuit board 13, and the current is likely to flow to the side of the lower resistive component. Accordingly, the static electricity generated in the vicinity of the connector 14 is escaped to the side of the metal face of the outer circumference of the HDD unit 3. As compared with the conventional structure, therefore, it is possible to remarkably prevent the semiconductor integrated circuits of the recording medium unit from being electrostatically broken.
  • As shown in FIGS. 5A and 5B, the HDD unit 3 is accommodated in the housing in the state where the HDD unit is clamped by the shock-absorbing members 4, and the metal plate 5 is accommodated in the housing in the state where the claw plates 5 d clamp the holding portions 4 a of the respective shock-absorbing members 4. Accordingly, all of the upper housing 1, the lower housing 2, and the metal plate 5 are not in contact with the HDD unit 3, and are spaced by a predetermined distance. In addition, the conductive member 6 is preferably formed by a member having flexibility. Even when any impact is applied from the outside to the upper housing 1, the lower housing 2, and the metal plate 5, therefore, the impact is hardly transmitted to the HDD unit 3 in a direct manner. Consequently, a high impact resistance can be realized.
  • The recording apparatus 100 has the driving portion which performs high-speed rotation, so that heat is generated in accordance with the high-speed rotation of the driving portion. The top cover 10 of the HDD unit 3 is in contact with the conductive member 6. Accordingly, heat generated in the surface of the top cover 10 can be transmitted to the conductive member 6 and the metal plate 5, and released from them. Namely, a structure with a high heat radiation property can be attained. In the embodiment, the slits 1 a are disposed in the housing on the side where the top cover 10 and the conductive member 6 are placed. Therefore, the heat radiation property can be further improved, and the reliability of the recording apparatus can be enhanced.
  • In the embodiment, it is particularly noted that the resistance to electrostatic breakdown and the heat radiation property can be improved by the relatively simple configuration without deteriorating the impact resistance of the recording apparatus. The metal plate 5 in the embodiment is accommodated in the housing, but alternatively the following configuration may be formed. Specifically, a part of the metal plate may be exposed from the housing to the outside, and static electricity may be discharged to the outside through the exposed portion of the metal plate (for example, a metal portion disposed on the outer surface of the upper housing 1 or the lower housing 2). As described above, the discharge may be alternatively performed from the metal plate 5 to a configuration other than the HDD unit 3 (for example, the upper housing 1, the lower housing 2, or an external apparatus on which the recording apparatus is installed).
  • Next, a recording apparatus 200 of a second embodiment of the invention will be described. FIG. 6 shows a sectional structure of the recording apparatus 200 in a position corresponding to a connector. The components which are similar to those in the recording apparatus 100 of the first embodiment are denoted by the identical reference numerals, and their description will be omitted.
  • In the recording apparatus 200 of the second embodiment, as shown in FIG. 6, as a conductive member which is electrically connected and interposed between the metal plate 5 and the metal face of the HDD unit 3 (the top cover 10), a gasket 21 is placed between the horizontal plate 5 b and the top cover 10. Usually, a gasket is a fixing seal member used for providing a structure with air-tightness and water-tightness. In the embodiment, an electrically conductive gasket is employed. Specifically, the gasket 21 in the embodiment has a structure where a filler cushion material 21 a such as urethane is covered with a thin metal plate 21 b.
  • As described above, also in the recording apparatus 200 of the second embodiment, the metal plate 5 and the metal face (the top cover 10) of the recording medium unit (the HOD unit 3) are electrically connected to each other through the gasket 21.
  • Similarly with the first embodiment, even when static electricity is generated in the vicinity of the connector 14, therefore, the static electricity is discharged to the top cover 10 through the metal plate 5 and the gasket 6. Accordingly, it is possible to remarkably prevent the semiconductor integrated circuits of the recording medium unit from being electrostatically broken, as compared with the conventional structure.
  • Next, a recording apparatus 300 of a third embodiment of the invention will be described. FIG. 7 shows a sectional structure of the recording apparatus 300 in a position corresponding to a connector. The components which are similar to those in the first and second embodiments are denoted by the identical reference numerals, and their description will be omitted.
  • In the recording apparatus 300 of the third embodiment, as shown in FIG. 7, as a conductive member which is electrically connected and interposed between the metal plate 5 and the top cover 10, a spring 30 is placed between the horizontal plate 5 b and the top cover 10. An example of the spring 30 used herein is a so-called coil spring in which a thin metal wire is helically wound.
  • As described above, also in the recording apparatus 300 of the third embodiment, the metal plate 5 and the metal surface (the top cover 10) of the recording medium unit (the HDD unit 3) are electrically connected to each other through the spring 30.
  • Similarly with the first and second embodiments, even when static electricity is generated in the vicinity of the connector 14, therefore, the static electricity is discharged to the top cover 10 through the metal plate 5 and the spring 30. Accordingly, as compared with the conventional structure, it is possible to remarkably prevent the semiconductor integrated circuits of the recording medium unit from being electrostatically broken. In addition, due to the elastic property of the spring, an impact which may be applied to the horizontal plate 5 b is reduced, so that the structure can attain high impact resistance.
  • As described above, according to the embodiments of the invention, the resistance to electrostatic breakdown can be improved with a relatively simple configuration.
  • An example of utilization of the above-described recording apparatus will be described. FIG. 8 schematically shows an example of the external appearance of a television broadcast receiving apparatus 111 on which the recording apparatus described in the respective embodiments is mounted.
  • Specifically, the digital television broadcast receiving apparatus 111 is mainly configured by a thin cabinet 112, and a supporting base 113 for supporting the cabinet 112 in its standing condition. In the cabinet 112, an image display apparatus 114 which is, for example, a flat panel display having a liquid crystal display panel, a pair of speakers 115, an operating portion 116, a light receiving portion 118 for receiving operation information transmitted from a remote controller 117, and the like are disposed.
  • A first memory card 119 such as an SD (Secure Digital) memory card, an MMC (Multimedia Card), or a memory stick is detachably attached to the television broadcast receiving apparatus 111. With respect to the first memory card 119, the recording and reproduction of information such as programs and photographs can be performed.
  • In addition, a second memory card (IC (integrated circuit) card) 120 in which, for example, contract information and the like are recorded is detachably attached to the television broadcast receiving apparatus 111. The reproduction of the contract information is performed on the second memory card 120.
  • The digital television broadcast receiving apparatus 111 comprises a first LAN (Local Area Network) terminal 121, a second LAN terminal 122, a USS (Universal Serial Bus) terminal 123, and an IEEE (Institute of Electrical and Electronics Engineers) 1394 terminal 124.
  • The first LAN terminal 121 is used as a port dedicated for a LAN-compatible HDD. The first LAN terminal is used for recording and reproducing information on and from a LAN-compatible HDD 125 which is a NAS (Network Attached Storage), through Ethernet (registered trademark).
  • As described above, by the provision of the first LAN terminal 121 as a port dedicated for a LAN-compatible HDD, the information recording of programs with a Hi-Vision image quality can be stably performed on the HDD 125 without being affected by the other network environments and the usage conditions of the network.
  • The second LAN terminal 122 is used as a general LAN-compatible port using Ethernet (registered trademark). The second LAN terminal is connected via, for example, a hub 126 to apparatuses such as a LAN-compatible HDD 127, a PC (Personal Computer) 128, and a DVD (Digital Versatile Disk) recorder 129 with a built-in HDD having a function of receiving digital broadcasting, and used for performing information transmission with these apparatuses.
  • With respect to the DVD recorder 129, the digital information transmitted via the second LAN terminal 122 is only the information of a control system. In order to transmit analog video and audio information with the digital television broadcast receiving apparatus 111, therefore, it is required to dispose a dedicated analog transmission path 130.
  • The second LAN terminal 122 can be connected to a network 132 such as Internet via a broadband router 131 connected to the hub 126, and is used for performing information transmission with various information terminals such as a PC 133 and a portable telephone 134 via the network 132.
  • The USB terminal 123 is used as a general USB-compatible port. The USB terminal is connected via a hub 135 to USB apparatuses such as a portable telephone 136, a digital camera 137, a card reader/writer 138 for a memory card, an HDD 139, and a keyboard 140, and used for performing information transmission with these USB apparatuses.
  • The IEEE 1394 terminal 124 is serially connected to an AV (audio video)-HDD 141, a D (digital)-VHS (Video Home System) 142, and the like each of which has a digital broadcast receiving function, and used for performing information transmission with these apparatuses.
  • FIG. 9 is a side view of the broadcast receiving apparatus 111. As shown in FIG. 9, the broadcast receiving apparatus 111 comprises a frame member 150, an image display device 114 attached to the frame member 150, the cartridge 101, and the recording apparatus 100, 200, or 300 which is detachably attached to the cartridge 101. Namely, the broadcast receiving apparatus 111 shown in FIG. 9 is a so-called television broadcast receiving apparatus with a built-in HDD. In the case where the capacity of the recording apparatus 100 is not enough, the user exchanges the recording apparatus 100, 200, or 300 in the cartridge 101 with another recording apparatus, so that the user can record a broadcast program into the new recording apparatus. As described above, the operation of exchanging a recording apparatus is required in the broadcast receiving apparatus 111 shown in FIG. 9, but the employed recording apparatus has the improved resistance to electrostatic breakdown. During the exchange operation of the recording apparatuses, therefore, it is possible to effectively prevent the recording apparatus from becoming unusable due to electrostatic breakdown.
  • FIG. 10 shows an example of a main signal processing system of the above-mentioned television broadcast receiving apparatus 111. Specifically, a satellite digital broadcast signal received through an antenna 243 for receiving digital BS/CS broadcasting is supplied to a tuner 245 for satellite digital broadcasting via an input terminal 244, whereby a broadcast signal of a desired channel is tuned.
  • The broadcast signal tuned by the tuner 245 is supplied to a PSK (Phase Shift Keying) demodulator 246, so that TS (Transport Stream) is demodulated. The TS is supplied to a TS decoder 247 to be decoded into a digital video signal, a digital audio signal, a digital data signal, and the like. Thereafter, the decoded signals are supplied to a signal processing portion 248.
  • A terrestrial digital television broadcast signal received by an antenna 249 for receiving terrestrial broadcasting is supplied to a tuner 251 for terrestrial broadcasting via an input terminal 250, whereby a broadcast signal of a desired channel is tuned.
  • The broadcast signal tuned by the tuner 251 is supplied to an OFDM (Orthogonal Frequency Division Multiplexing) demodulator 252, so that TS is demodulated. The TS is supplied to a TS decoder 253, so that the TS is decoded into a digital video signal, a digital audio signal, a digital data signal, and the like. Thereafter, the decoded signals are supplied to the signal processing portion 248.
  • In the television reception, the signal processing portion 248 selectively performs a predetermined digital signal process on the digital video and audio signals supplied from the TS decoders 247, 253, so that the processed results are supplied to a graphic processing portion 254 and an audio processing portion 255. The TS decoders 247, 253 supply data to an EPS production controlling portion 256 included in a control section 261.
  • The signal processing portion 248 and the TS decoders 247, 253 supply to the control section 261 various data for acquiring programs, electronic program guide (EPG) information, program attribute information (program genre, and the like), caption information (service information, SI, or PSI). The control section 261 includes a program table production control portion 290. The program table production control portion 290 produces an EPG from the input information. The control section 261 performs a image generation process for displaying an EPG and caption produced based on the program table production control portion 290, and supplies the generated image information to the graphic processing portion 254.
  • The graphic processing portion 254 has a function of superimposing an OSD signal generated in an OS (On Screen Display) signal generating portion 257 on the digital video signal supplied from the signal processing portion 248, and outputting the resulting signal. The graphic processing portion 254 can selectively output one of the output video signal of the signal processing portion 248 and the output OSD signal of the OSD signal generating portion 257, and alternatively can output both of the output signals in a combination manner in which each of them constitutes a half of the screen.
  • The digital video signal output from the graphic processing portion 254 is supplied to the video processing portion 258. The video processing portion 258 converts the input digital video signal into an analog video signal of a format which can be displayed by the video display apparatus 114. Thereafter, the analog video signal is supplied to the video display apparatus 114 to display an image, and further supplied to the outside via an output terminal 259.
  • The audio processing portion 255 converts the input digital audio signal into an analog audio signal in a format which can be reproduced by the speakers 115. Thereafter, the analog audio signal is supplied to the speakers 115 for reproducing the sound, and further supplied to the outside via an output terminal 260. The television broadcast receiving apparatus 111 is provided with a clock 280 for indicating the current time.
  • In the television broadcast receiving apparatus 111, all of the operations thereof including the above-described various receiving operations are generally controlled by the control section 261. The control section 261 incorporates a CPU (Central Processing Unit) and the like, and receives operation information from the operating portion 116, or receives operation information from the remote controller 117 via the light receiving portion 118, so that the respective portions are controlled so as to reflect the operation contents.
  • In this case, the control section 261 mainly utilizes a ROM (Read Only Memory) 261 a for storing control programs which are to be executed by the CPU, a RAM (Random Access Memory) 261 b for providing a working area for the CPU, and a nonvolatile memory 261 c in which various setting information, control information, and the like are stored.
  • The control section 261 is connected to a card holder 266 to which the first memory card 119 can be attached, via a card I/F (Interface) 265. Accordingly, the control section 261 can perform information transmission with the first memory card 119 attached to the cardholder 266, through the card I/F 265.
  • In addition, the control section 261 is connected to a card holder 268 to which the second memory card 120 can be attached via a card I/F 267. Accordingly, the control section 261 can perform information transmission with the second memory card 120 attached to the cardholder 268, through the card I/F 267.
  • The control section 261 is connected to the first LAN terminal 121 via a communication I/F 269.

  • (Modifications)
  • In the embodiments, the electric connection between the metal plate 5 and the HDD unit 3 is formed by using any conductive member. By changing the shape of the metal plate 5, the metal plate 5 and the HDD unit 3 can be configured so as to be directly connected to each other. As shown in FIG. 11, for example, an end portion of the horizontal plate 5 b may be caused to stand substantially vertically, so that a vertical plate 5 e which is parallel to the vertical plate 5 a is provided, and a horizontal plate 5 f which is continuous to a lower portion of the vertical plate Se, and which is horizontally bent may be disposed.
  • According to the configuration, the metal plate 5 and the top cover 10 are electrically connected to each other, so that, even when static electricity is generated in the vicinity of the connector 14, the static electricity is discharged directly to the top cover 10 through the metal plate 5. As compared with the conventional structure, therefore, it is possible to prevent the semiconductor integrated circuits of the recording medium unit from being broken by the static electricity.
  • The invention is not limited to the above-described embodiments. In the process of carrying out the invention, the components may be modified and embodied without departing from the spirit of the invention. For example, the shape of the opening 20 of the metal plate 5 may be appropriately changed in accordance with the shape and position of the connector. Specifically, a plurality of openings 20 may be disposed in the vertical plate 5 a, or the opening 20 may be extended up to the horizontal plate, as shown in FIG. 12A.
  • In the embodiments, the single metal plate 5 is disclosed. Alternatively, as shown in FIG. 12B, a plurality of metal plates which are mutually separated (a first metal plate 5 g and a second metal plate 5 h) may be placed in the vicinity of the connector 14. In the alternative, the connector 14 is exposed to the outside through a gap between the first metal plate 5 g and the second metal plate 5 h. In this case, in order to improve the resistance to electrostatic breakdown, it is preferred to form a configuration in which static electricity can be discharged from both of the first metal plate 5 g and the second metal plate 5 h. For example, each of the first metal plate 5 g and the second metal plate 5 h is electrically connected to the top cover 10 of the HDD unit 3 through or not through a conductive member.
  • In the embodiments, the vertical plate 5 a is disclosed. Alternatively, as shown in FIG. 12C, a metal plate 5 i may be configured so as to have a metal portion which is inclined to the principal surface of the HDD unit 3. In this way, when the metal plate is placed in the vicinity of the connector 14, the connector 14 is placed so as to be exposed to the outside, and static electricity is discharged through the metal plate, the configuration of the metal plate such as the shape and position can be appropriately changed. In the embodiments, the metal plate and the top cover 10 of the HDD unit 3 are electrically connected to each other. Alternatively, the metal plate and the base chassis 11 can be electrically connected to each other. By appropriate combinations of plural components disclosed in the embodiments, various inventions can be configured. For example, some of the components can be omitted from all of the components shown in the embodiments. Moreover, the components in different embodiments can be appropriately combined.
  • As described with reference to the embodiment, there is provided a recording apparatus in which the resistance to electrostatic breakdown is improved, and a broadcast receiving apparatus comprising such a recording apparatus.
  • In the embodiment, the metal plate is disposed in the vicinity of the connector, and the metal plate and the metal face of the recording medium unit are electrically connected to each other. Even when static electricity is generated in the vicinity of the connector, therefore, the static electricity is discharged to the metal face of the recording medium unit through the metal plate. Therefore, as compared with the conventional structure, it is possible to prevent the recording apparatus from being electrostatically broken, and the reliability can be enhanced.
