As shown in Figure 7, use multicore cable as signal cable 25.This signal cable 25 is made of the crust 66 of many former lines (plain line) 65, the shielding line (not shown) of tying up many former lines 65, coating shielding line.And many former lines 65 are welded in main circuit substrate 57 and electronic circuit substrate 58 with shielding line.In addition, the former line 65 of each of signal cable 25 is connected respectively with electronic circuit substrate 58 and main circuit substrate 57, replaces in this, also can be directly be connected with a side wherein.
As shown in Figure 8, reinforced bulkhead 59 is made up of with being connected with in side plate 59b, the 59c at these two ends base plate 59a, and cross section forms U word or tunnel-shaped, is formed with peristome 59d on top.This reinforced bulkhead 59 is divided into the reinforced bulkhead main body 70 of taking in prism 53 and electronic circuit substrate 58, ensuing necking down (strand り) portion 71 and signal cable installation portion 72.And at one end the reinforced bulkhead main body 70 of side is fixed with prism holding member 54, and is fixed with the crust 25a of signal cable 25 at another distolateral signal cable installation portion 72.
Reinforced bulkhead main body 70 is made as prism 53 and electronic circuit substrate 58 foldable cross-sectional areas, and signal cable installation portion 72 is made as the cross-sectional area of the crust 25a that can take in signal cable 25.Therefore, necking part 71 according to along with towards signal cable installation portion 72 and cross-sectional area draw close and the mode that reduces gradually tightens to a side.In addition, as shown in Figure 6, through this necking down, the optical axis CL1 of imaging lens system 51 and the central shaft CL2 of signal cable 25 become shift state.The side-play amount of X-direction (horizontal line direction) is OFx, and the side-play amount of Y direction (vertical direction) is OFy.The position of signal cable 25 is with respect to the stagger amount of these two side-play amount OFx, OFy of camera head installing hole 45 (with reference to Fig. 2).
The side-play amount OFx of X-direction, the side-play amount OFy of Y direction can be through changing reinforced bulkhead 59 the shape of necking part 71 suitably change.Thus, can make signal cable 25 with respect to the configuration of staggering of the optional position of optical axis CL1 in the face that contains the XY axle.
As shown in Figure 8, base plate 59a extend to be provided with towards the rear, is formed with than side plate 59b, 59c to the outstanding joint fastener 75 in rear more.Both side edges is formed with card claw stop 76 in the rear end of this joint fastener 75.
Shown in Figure 7, joint fastener 75 is formed on and twines bounding wire 78a under the periphery lower surface state of contact with signal cable 25, makes joint fastener 75 and signal cable 25 incorporate windings (yarn volume) 78.In addition, before forming winding 78, make crust 66 lining thermal contraction coated tubes 77 according to the mode that covers former line 65 and shielding line, so that the shielding line of signal cable 25 does not contact with reinforced bulkhead 59.And winding 78 utilizes bonding agent 79 affixed (set).Between coated tube 77 and crust 66, also be coated with bonding agent 79 and they are integrated.Constitute cable holder 61 through these windings 78 and bonding agent 79.Improve the bond strength of signal cable 25 and reinforced bulkhead 59 through this cable holder 61.
Because the front end face 76a of card claw stop 76 is limited to the rear end of winding 78; Therefore, through the bending operation push pull signal cable 25 of bending section 32, even the power of this push-and-pull works to this cable holder 61; Owing to improve bond strength through card claw stop 76, winding 78, bonding agent 79; Therefore, signal cable 25 can not depart from reinforced bulkhead 59 yet, can suppress the generation of the peeling off of the portion that is welded to connect, breakage etc. of former line 65.
In addition, according to covering signal cable 25 is wound in winding 78 and the mode that is coated with bonding agent 79 on it on the joint fastener 75, flexible protecting tube 80 is covered.Through the cable holder 61 that are covered with this protecting tube 80, during at the bending operation that passes through bending section 32 and by bending, bending force not only is scattered in signal cable 25, but also disperses to give protecting tube 80, therefore, can realize the protection to signal cable 25.
Like Fig. 4 and shown in Figure 6, when prism kept framework 54 to be fixed in reinforced bulkhead 59, under three of prism 53 states that covered by base plate 59a and side plate 59b, 59c, prism 53, electronic circuit substrate 58 were accommodated in the reinforced bulkhead 59.In addition, the deep card in front side that on side's side plate 59b, is formed with the side plate 54a of prism holding member 54 ends opening 85.This card ends opening 85 and extends to the position at rear more than side plate 54a, between them, is formed with the gap 85a that is used to discharge the residue bonding agent.
As shown in Figure 2, for camera head 26, prism holding member 54 inserts in the camera head installing hole 45 of leading section main body 35, and fixing through hold-down screw (not shown).In addition, as shown in Figure 9, be separately installed with two photoconductions 87,88 with two illuminating windows, 41,42 corresponding positions.Supplying gas in addition ,/delivery nozzle 43 is connected with snorkel 89 and flow pipe 90.
Fig. 9 representes the cross section with the orthogonality of center shaft of bending section 32.This cross section can be divided into four zones with 90 ° of intervals through two imaginary lines 91.Imaginary line 91 is the line that will connect at a pair of connecting pin 39 of point-symmetric position configuration with respect to the central shaft of a plurality of joints ring 38, and these two imaginary lines 91 are observed from central axis direction between adjacent connecting pin 39 and reported to the leadship after accomplishing a task with an angle of 90 degrees degree.At the first interval 92a configuration pliers passage 19.Dispose first photoconduction 87 at second area 92b.At the 3rd regional 92c configuration signal cable 25 and second photoconduction 88, at the 4th regional 92d configuration snorkel 89 and flow pipe 90.
Through the bending operation of bending section 32, the power (transversal force) that acts on the transverse direction of pliers passage 19 strengthens in the diagonal through the angle central shaft.With respect to the angle central shaft; Roughly diagonal position configuration signal cable 25 at pliers passage 19; And the crooked behavior of the pliers passage 19 that causes with respect to the bending operation by bending section 32, rigidity is arranged than pliers passage 19 signal cable 25 of time (the high い of inferior To) slightly in the position configuration that obtains rigid balancing.Therefore, can successfully obtain angular distortion one side's balance with respect to flexure operation.
In addition, through acting on the transversal force of pliers passage 19, the power that other tubing diagonal angle is moved works.Relative therewith, utilize side-play amount, among each the interval 92a~92d in the bending section 32, with respect to the pliers passage 19 of first area 92a the 3rd regional 92c configuration signal cable 25 at diagonal position based on the necking part 71 of reinforced bulkhead 59.Thus, with respect to the displacement of the pliers passage 19 of the bending of bending section 32, the diagonal position configuration signal cable 25 that the variation of the position that can bring in the influence because of its displacement is minimum can correspondingly prevent malalignment.Therefore, the damage of signal cable 25 and photoconduction 88 is reduced, can suppress the generation of the fracture etc. of signal cable self.
Figure 10 is with respect to the configuration of inner matter shown in Figure 3 example, with first illuminating window 41 with supply gas/figure of the position transposing of delivery nozzle 43.In this case, shown in figure 11, the side-play amount of the necking part 71 through utilizing reinforced bulkhead 59 energetically at the first interval 92a configuration pliers passage 19, disposes first photoconduction 87 at second area 92b.At the 3rd regional 92c configuration signal cable 25, snorkel 89, flow pipe 90, dispose second photoconduction 88 at the 4th regional 92d.
In the configuration example of Figure 10 and Figure 11, identical with the configuration example of Fig. 9, can obtain to alleviate the effect of pliers passage 19 with respect to the stress (ス ト レ ス) of signal cable 25, the durability of signal cable improves.In addition, the offset configuration of the optical axis of imaging lens system 51 and signal cable 25 is not limited to the configuration like Fig. 9 and Figure 11.For example, also can with respect to the central shaft of bending section 32 when the diagonal position configuration signal cable 25 of pliers passage 19, make signal cable 25 further near pliers passage 19.In this case, through making pliers passage 19 and signal cable 25 approaching, realize the thin footpathization of flexible portion 33.
As above, utilize the reinforced bulkhead 59 of camera head 26, carry out signal cable 25 and the location of pliers passage 19 in the bend 32, and inner matters such as other photoconduction 87,88 also obtain curved slowly (slow い) position limit effect of this reinforced bulkhead 59.Thus, even under the situation of bending section 32 bendings, near cable holder 61, also can suppress tubing and cross the generation of pin 39 at the mobile malalignment in each zone.In addition, when crossing pin 39, do not make tubing oppressed, can suppress the generation of the broken string of signal cable because of pin 39.And; Utilization is based on the curved slowly position limit effect of each pipe of reinforced bulkhead 59; Become the good configuration of balance in the gap of in each regional 92a~92d, guaranteeing each tubing, and the increase of the resistance to sliding of each tubing during flexure operation that also can suppress to cause because of inadequate balance.
In this embodiment; Through the rear end side at prism 53 promptly be disposed at main circuit substrate 57 below reinforced bulkhead 59 in be provided with electronic circuit substrate 58, shortly process former line 65, or former line 65 folded be accommodated in the reinforced bulkhead 59 etc., can make cable holder 61 and main circuit substrate 57 near.Shown in Figure 12 (A), it can make the amount of short and smallization of the length direction L1 of camera head 26.Thus, in front end tube 37, cable holder 61 is positioned at than first joint ring 38a more near front.
On the other hand, shown in Figure 12 (B), under the situation of the rear end side after cable holder 61 is positioned at first joint ring 38a, the part in cable holder 61 dead asterns becomes the variation in rigidity point, worries its stress concentration and breaks.Relative therewith, through being set at the cable fixed position of Figure 12 (A), even at bending section 32 for example under the crooked situation of maximum limit, signal cable 25 bendings also reduce near cable holder 61.Thus, signal cable 25 is described slow sweep and bending, and in addition, the bending power that acts on cable holder 61 diminishes.Consequently the durability of signal cable improves.
And, in Figure 12 (B), being positioned at first joint ring 38a owing to have inflexible cable holder 61, therefore, might interfere with other photoconduction etc.In this embodiment, be positioned at first joint ring 38a owing to have the signal cable 25 of flexibility, so these worry also to eliminate.Like this, even under the situation of bending section 32, through changing the position of cable holder 61 at fore-and-aft direction, can reduce the bending force that acts on cable holder 61, and eliminating worry to the breakage of other tubing with identical angular bend.
In addition,, can cable holder 61 be disposed in the front end tube 37, therefore, add the effect of the skew effect of reinforced bulkhead 59, can further improve the durability of the inner matter in the bending section 32 through short and smallization of camera head 26.In addition, the only configuration of the signal cable 25 in offset effect through above-mentioned reinforced bulkhead 59 or the front end tube 37 can improve the durability of the inner matter in the bending section 32.Therefore, as long as satisfy one of which side at least, just can realize problem of the present invention.
In the above-described embodiment, in reinforced bulkhead 59 the filling bonding agent as sealing resin 60.Also can replace this filling,, each inner matter is sealed in the reinforced bulkhead 59 through prism holding member 54, electronic circuit substrate 58 etc. are set under the state of bonding agent being put into reinforced bulkhead 59.
In addition, in the above-described embodiment, use main circuit substrate and electronic circuit substrate, but also can save the electronic circuit substrate.In this case, use a distolateral imaging apparatus that is equipped with, make other end side be bent into the crooked circuit substrate of U font.This crooked circuit substrate can or also can be the circuit substrate of hard for flexible circuit board.
In the above-described embodiment, employing will utilize prism to make the crooked imaging apparatus traverse mode of optical axis, but also can save prism and put imaging apparatus is vertical.In addition, many former lines that constitute signal cable are integrated with adhesive securement, but also can be that it is not integrated.In addition, be made as guiding gutter (Gutter) shape as the reinforced bulkhead of biasing element, as long as but can make the central shaft skew of the optical axis and the signal cable of lens barrel, then can be tubular, also can be for tabular.And the object of constant offset parts also can be the leading section main body except that lens barrel.In this case, form the acceptance division of biasing element in the leading section main body, and to the leading section of its chimeric biasing element.
