Abstract
Description
- The invention relates to a motor switching apparatus installed on a motor for use in equipment that requires multiple power outputs, such as multi-function printers (MFPs), and particularly a motor switching module that employs a rotary disk to switch phases.
- Nowadays office machines such as copiers, printers, facsimile machines and scanners are indispensable information equipment in the office environment. All business and administrative tasks are closely tied to these machines. Each office machine occupies a site. Adding it all together, they take a lot of space and become a great burden to the work environment that has spatial constraints. In addition, each office machine has different functions. Utilization frequency of these single function office machines is also different. Some office machines are not frequently used. But in order to meet business requirements, they still have to be procured and installed.
- In order to remedy the problems set forth above, Multi-Function Peripherals (MFPs) have been developed and introduced. These MFPs integrate the functions of copying, printing, facsimile and scanning. Users can process a wide range of office tasks by procuring only one MFP. As a result, a large amount of space and cost is saved. Moreover, the MFP often provides a simple operation interface and becomes an All-in-one device.
- A conventional MFP generally has a scanner device located on the upper side to process scanning operations. Coupled with the setting of the microprocessor and communication lines, it also can perform facsimile functions after the scanning operation is done. The machine further has a printing device located therein. There is a paper-feeding device located on one side of the machine. With the printing device and the paper-feeding device coupled together, printing operations may be performed. Thus the motion mechanism of the MFP includes at least devices for scanning, printing and paper feeding. The scanner device includes a CCD to be moved reciprocally, a transmission belt engaged with the CCD, and a driving motor coupled with the transmission belt to provide rotation power. The printing device may be an inkjet or laser printer using carbon powders driven by a motor. The inkjet device includes a carrier that holds the ink cartridge and moves reciprocally, a transmission belt engaged with the carrier, and a driving motor coupled with the transmission belt to provide rotation power. The paper-feeding device includes a rotary paper feeding barrel, a transmission gear set engaging with a paper feeding axle, and a driving motor engaged with the transmission gear set to provide rotation power.
- In the aforesaid MFP, the devices and the driving motors are coupled in an one-on-one fashion. The rotation power required by one device is provided by one driving motor. Such a design merely puts one scanner and one inkjet printer in a machine. While the electronic circuits are integrated, in terms of their mechanisms, each device still operates independently. Hence they are not truly integrated. The number of the driving motors is not reduced, and the driving motors take a significant portion of the cost and occupy a great amount of space in the machine.
- The primary object of the invention is to resolve the problems set forth above. The invention provides a phase rotary disk motor switching module to optimize the utilization of motor power and enable a single motor to provide multiple power output.
- The phase rotary disk motor switching module of the invention consists of a rotary disk, an output gear, a retaining element, a plurality of phase gears and a plurality of driven gears corresponding to the phase gears. The rotary disk is coupled to a motor. The motor has a power output shaft coupled with a driving gear. The phase gears are located on the periphery of the rotary disk and are coupled with the driving motor. The peripheral rim of the rotary disk has a plurality of anchor notches. The retaining element may latch on one of the anchor notches to enable the rotary disk to define a plurality of corresponding phases. Each phase has an adjacent driven gear coupled with one phase gear. Thus motor power may be transmitted through the driving gear, phase gears and driven gears and output to provide a plurality of power output phases.
- When the motor rotates in the positive direction, it drives the rotary disk and enables the retaining element to selectively switch to various phases. When the motor rotates in the reverse direction, the rotary disk is prevented from turning due to the restriction of the retaining element. Meanwhile, the driving gear may be driven by the motor to transmit power through the phase gear on a selected phase to the coupled driven gear.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

- FIGS. 7A and 7B are schematic views of the invention adopted on an MFP for driving a CCD to perform scanning operations.
- Referring to FIGS. 1A, 1B and1C, the phase rotary disk motor switching module of the invention consists of a mounting
board 10, arotary disk 20, a retainingelement 12 and a plurality of gear sets. The mountingboard 10 has a back side with a motor mounted thereon (not shown in the drawings). The motor has apower output shaft 50 extending to the front side of the mount board. Therotary disk 20 is mounted on thepower output shaft 50. Thepower output shaft 50 is coupled with adriving gear 201 for transmitting motor power. Of course, other types of gear sets may also be used to transmit the motor power. - The peripheral rim of the
driving gear 201 couples with a plurality of phase gears which include afirst phase gear 41, asecond phase gear 42, athird phase gear 43 and afourth phase gear 44. The peripheral rim of therotary disk 20 has a plurality of anchor notches which include afirst anchor notch 21, asecond anchor notch 22, athird notch 23 and afourth anchor notch 24. The retainingelement 12 is located at one side of therotary disk 20 and is pivotally engaged with the mountingboard 10 by means of apintle 13 to enable the retainingelement 12 to swing radially towards therotary disk 20 to selectively latch on one of the anchor notches. When the retainingelement 12 latches on the anchor notch, therotary disk 20 can rotate only in one direction (such as the clockwise direction shown in the drawings) due to the restriction of the retainingelement 12. When the retainingelement 12 latches onto different anchor notches, therotary disk 20 defines different phases, i.e. the first, second, third and fourth anchor notches correspond respectively to the first, second, third and fourth phase states. - When the motor rotates in the positive direction (clockwise direction), it also drives the
rotary disk 20 to rotate in the clockwise direction. Because the anchor notches have stopping and guiding functions, the retainingelement 12 may be switched to different phases. Thefirst anchor notch 21 is taken as an example to explain the phase switching operation as follows. Thefirst phase notch 21 has astop section 211 substantially parallel with the radial direction of therotary disk 20 and aslide section 212 connecting to thestop section 211. The retainingelement 12 has a front end parallel with thestop section 211 and formed in a shape to match thestop section 211. Thus the retainingelement 12 may contact thestop section 211 of thefirst notch 21 and maintain contact through an elastic element, which has two ends located respectively on the mountingboard 10 and the retainingelement 12 so that therotary disk 20 is prevented from turning counterclockwise. While the drawings show that the elastic element is aspring 11, it is by no means limited to this. Theslide section 212 is a smooth curve. When therotary disk 20 rotates in the clockwise direction, it guides the retainingelement 12 to swing outwards about thepintle 13 as shown in FIG. 2A. When therotary disk 20 is driven by the motor to rotate continuously, the retainingelement 12 slides along theslide section 212 of thefirst anchor notch 21 until it moves away from the first anchor notch 21 (as shown in FIG. 2B). - When the
rotary disk 20 rotates clockwise continuously, the retainingelement 12 moves continuously to stop at thesecond anchor notch 22, thethird anchor notch 23 and thefourth anchor notch 24, and enables therotary disk 20 be positioned sequentially at the second phase, the third phase and the fourth phase (referring to FIGS. 3A-3C). At each phase, there is a phase gear coupling with a driven gear. For the first phase to the fourth phase, thefirst phase gear 41, thesecond phase gear 42, thethird phase gear 43 and thefourth phase gear 44 couple with the first drivengear 31, the second drivengear 32, the third drivengear 33 and the fourth driven gear 34 (referring to FIGS. 1C, 3A, 3B and 3C). In the mean time, the motorpower output shaft 50 rotates in a counterclockwise (or reverse) direction. As therotary disk 20 is prevented from turning due to the restriction of the retainingelement 12, thedriving gear 201 may transmit motor output power through the phase gear to the driven gear. Taken the fourth phase for example. As shown in FIG. 3C, thedriving gear 201 engages with thefourth phase gear 44, which in turn engages with the fourth drivengear 34, hence motor power may be transmitted through thedriving gear 201,fourth phase gear 44 and fourth drivengear 34 to a device coupled with the fourth drivengear 34 to provide power required in the device. Similar operation principles may be applied to other three phases. Thus the power of a single motor can be transmitted to four different phases (or four devices). - On the other hand, in order to prevent the
rotary disk 20 from turning counterclockwise during phase switching and resulting in thedriving gear 201 transmitting power through the phase gear to the coupled driven gear and making wrong movements, thedriving gear 201 may be coupled with a one-way bearing to mount on the motor power output shaft. This can prevent faulty operations from occurring. Of course, the number of the phase is not limited to four. It may be more or less according to requirements. - By means of the arrangement set forth above, the rotation speed and direction of every driven gear are the same. However, such a design does not necessary meet all the requirements. Hence based on different requirements, a plurality of gear sets may be added to the driven gears to change and control the rotation speed and direction. To achieve this purpose, gears may be added between each phase gear and the
driving gear 201. Referring to FIG. 4, afirst gear 51, asecond gear 52, athird gear 53 and a fourth gear 54 are added respectively to thefirst phase gear 41,second phase gear 42,third phase gear 43 andfourth phase gear 44 to control the speed reducing ratio. Furthermore, in order to ensure that therotary disk 20 is anchored on the desired phase after having stopped for a period of time and to prevent faulty operations, apositioning sensor 60 may be installed at one side of therotary disk 20 to monitor and control the phase of therotary disk 20. - Refer to FIGS. 6A and 6B for an embodiment of the invention adopted on an MFP. The first driven
gear 31 and the third drivengear 33 are used on a paper-feedingsystem 70, while the second drivengear 32 and the fourth drivengear 34 are used on ascanner system 80. First, therotary disk 20 is switched to the first phase (as shown in FIG. 6A), and the first drivengear 31 is coupled with a plurality of gear sets to feedpaper 9 from apaper cartridge 71 into the paper-feedingsystem 70. Then therotary disk 20 is switched to the third phase. By the driving of the third drivengear 33,paper 9 is turned and fed into the scanner system 80 (shown in FIG. 6B). - Next, the
rotary disk 20 is switched to the second phase or the fourth phase (referring to FIGS. 7A and 7B). By coupling the second drivengear 32 or the fourth drivengear 34 with thescanner system 80, and through a plurality of gear sets, power may be transmitted to aCCD 81, and through different phases of therotary disk 20. Thus theCCD 81 may be moved reciprocally to perform the scanning operation. Therefore the two systems that require motors (the paper feeding-system and scanner system) may be integrated and served by one single motor. Of course, applications of the invention are not limited to MFPs or scanner and paper feeding systems. Any equipment that requires multiple motor output may be integrated through the invention. - In summary, the phase rotary disk motor switching module of the invention employs anchor notches on the peripheral rim of a rotary disk to couple with a retaining element to define a plurality of phases. Every phase has a corresponding phase gear to couple with an adjacent driven gear to transmit output power. Thus by the switching of the rotary disk, motor power may be transmitted through different positions to maximize the utilization of one single motor.
- While the preferred embodiment of the invention has been set forth for the purpose of disclosure, modifications of the disclosed embodiment of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
