Friction plate 61 is made of the roughly discoideus high friction member with increased pressure board 60 roughly the same diameters, the through hole 61a of the roughly the same diameter of the second axle part 34b of heart portion formation therein and fulcrum 34.This friction plate 61 is clamped into finger plate 32 and 60 ground configurations of increased pressure board with the state that the second axle part 34b of fulcrum 34 runs through through hole 61a.
Therefore, in this first friction mechanism 57, by pushing increased pressure board 60 at fixed head 31 and 32 latch plates that are compressed 59 of first finger plate, this increased pressure board 60 is pushed to friction plate 61, thereby can produce the friction of appropriateness.
Second friction mechanism 58 with the ring portion 46 of above-mentioned periphery ring flat-plate 45, has latch plate 63 with the state configuration that is compressed for the outer circumferential side 32 of fixed head 31 and finger plates produces friction between the peripheral part of fixed head 31 and finger plate 32.
Latch plate 63 is made of the roughly circular metallic plate with the ring portion 46 roughly the same diameters of periphery ring flat-plate 45, has the rugose shape of integrally bending on thickness direction.In addition, along circumferentially with the peripheral part of this latch plate 63 position of 2 five equilibriums roughly, the interarea of a pair of spacer 64 relative these latch plates 63 that becomes the spline member of this latch plate 63 is bent to form by the right angle.On the other hand, on fixed head 31, form a pair of location hole 65 that engages with this a pair of spacer 64.This latch plate 63 is fixed to fixed head 31 by joining a pair of spacer 64 to a pair of location hole 65, being positioned under the state between the peripheral part that is clamped into the fixed head 31 and first finger plate 32.
In this second friction mechanism 58, the latch plate 63 that is compressed between the peripheral part of the fixed head 31 and first finger plate 32 is pushed first finger plate 32, the peripheral part of this first finger plate 32 is pushed to the ring portion 46 of periphery ring flat-plate 45, thereby can produce the friction of appropriateness.
In this turning hinge mechanism 20, first friction mechanism 57 and second friction mechanism 58 are set, thereby main part 2 suitably and stably keeps handle portion 4 in angle position arbitrarily relatively.Wherein, this first friction mechanism 57 and second friction mechanism 58 are supported between main part 2 and the handle portion 4 pivotally, simultaneously, are used for applying friction at the interior all sides and the outer circumferential side of 32 of fixed head 31 and first finger plates.
In addition, in this turning hinge mechanism 20, even the first such friction mechanism 57 and the occasion of second friction mechanism 58 are being set, also can easily pass first peristome 40 and second peristome 54 and arrange wire harness 66, can not become the obstacle of the wire harness of between main part 2 and handle portion 4, arranging 66 at main part 2 and 4 of handle portions.
In addition, in this turning hinge mechanism 20,, can will not rub maintenance necessarily to the latch plate 59 of inboard and the pushing of latch plate 63 of outer circumferential side even be provided with the detent mechanism that when handle portion 4 revolutions, applies the sense of joint degree in the precalculated position with exerting an influence yet.
Therefore, in digital camera 1 with such turning hinge mechanism 20, but the further miniaturization of implement device integral body, simultaneously, main part 2 suitably and stably keeps handle portion 4 in angle position arbitrarily relatively.
In above-mentioned digital camera 1, as shown in Figure 11, the wire harness 66 that is used to be electrically connected main part 2 sides and handle portion 4 sides passes first peristome 40 and second peristome 54 of turning hinge mechanism 20, arranges between the enclosure interior of the enclosure interior of main part 2 sides and handle portion 4 sides.
Here, first peristome 40 and second peristome 54 form in the mode that overlaps at least a portion at handle portion 4 relative main part 2 rotating angular ranges (here being 90 ° angular range) as Figure 12 and as shown in Figure 13.
In this occasion, can gently bend the wire harness of between main part 2 and handle portion 4, arranging 66 (below weigh folded portion 67) between first peristome 40 that overlaps and second peristome 54, in addition, can easily pass this overlapping 67 layout wire harness 66.
Specifically, wire harness 66 is the flexible circuit board (to call FPC66 in the following text) of the long size that forms by preset width as shown in Figure 14, with the mode of the revolution action that can follow handle portion 4 therebetween part be provided with the bend 66a of bending in interarea.This bend 66a is the part of turning back as shown in Figure 15 between first peristome 40 that overlaps and second peristome 54, have and be the roughly the same radius of curvature of radius of curvature of first peristome 40 and second peristome 54 at center with fulcrum 34.
This FPC66 such as Figure 11, Figure 12 and as shown in Figure 13, its bend 66a passes between first peristome 40 and second peristome 54 overlapping 67 and gently turns back by U font roughly, simultaneously, distolateral second peristome 54 that passes of one arrives main part 2 sides, and its another distolateral first peristome 40 that passes arrives handle portion 4 sides.
At this, the FPC66 that turns back in overlapping 67 follows the revolution action of a pair of finger plate 32,33 relative fixed plates 31, and the folded back position of the bend 66a in overlapping 67 is changed.
At this moment, a pair of finger plate 32,33 relative fixed plates 31 rotating angles shown in Figure 11 are β, and the angle of the folded back position of FPC66 shown in Figure 15 displacement becomes β/2.Therefore, in order to form overlapping 67 54 of first peristome 40 and second peristomes, the angular range that need make first peristome 40 and second peristome 54 at least is more than or equal to half of handle portion 4 relative main part 2 rotating maximum angles (β m).
Specifically, as shown in Figure 12, in order to make the connector 68 that is installed on FPC66 pass the angular range of first peristome 40 after the assembling of above-mentioned turning hinge mechanism 20 easily, the angular range of this first peristome 40 becomes and roughly the same 90 ° of handle portion 4 relative main part 2 rotating angular ranges (β m).In addition, at first peristome 40, be used to protect first ways 69 of FPC66 to pass ring portion 46 inboards of periphery ring flat-plate 45, to sandwich the state configuration between the fixed head 31 and first finger plate 32.
