Fig. 5 is the figure of its distribution structure of explanation.

At Fig. 5 (b), presentation video transmits the distribution structure with flexible substrate FR1, if assembling is in the flexible substrate FR1 of the state of Fig. 5 (b), then becomes the formation shown in Fig. 5 (a).The flexible substrate FR1 of the shape shown in this Fig. 5 (a) together is installed in the housing (basket) of mobile device with keeping module 202 with screw.

At first the image of key diagram 5 transmits the distribution structure with flexible substrate FR1.

Shown in Fig. 5 (b), at flexible substrate FR1, has the boundary member shunt (branch divides) between the 1st region R EG1 and the 2nd region R EG2, and extend to the 3rd region R EG3 camera module 200 sides, that be pasted with stiffening plate B along the 1st region R EG1, fold fixing by making the 3rd region R EG3 be overlapped in the 1st region R EG1, become the formation shown in Fig. 5 (a), form movement limiting portion P at boundary member.Need to prove, stiffening plate B for the intensity that makes mobile confinement plate P fully and improve function setting.For this reason, even from region R EG2 drawing flexible substrate FR1, because of can still not forming the state of deflection to the 1st region R EG1 working tension in the 1st region R EG1 side because have this movement limiting portion P.In addition, owing to study intensively, do not increase the involving property effect of distribution with parts so can access at the shape of a flexible substrate.

That is, have: of the present invention, image unit the 1st zone nearby, and the 1st zone of continuing, leave the 2nd zone of a side from image unit.And possess movement limiting portion, the boundary member of described movement limiting portion between the 1st zone and the 2nd zone, and by limiting the effect of tension force to the 1st zone of avoiding of moving of this boundary member.

Fig. 6 represents that FR1 is same with flexible substrate, and the flexible substrate FR2 that is used for hot-wire coil also is suitable for the figure of the example when of the present invention.

At the distribution structure of Fig. 6 (a) expression coil drive,, then become the formation shown in Fig. 6 (a) if assembling is in the flexible substrate FR2 of the state of Fig. 6 (b) with flexible substrate FR2.

Shown in Fig. 6 (b), at flexible substrate FR2, has boundary member between the 1st region R EG11 and the 2nd region R EG21 by along separate routes, and extend to the 3rd region R EG31 camera module 200 sides, that attach stiffening plate B1 along the 1st region R EG11, (テ-プ) (part of being represented by hachure among the figure) is pasted and fixed on yoke 204B with the 3rd region R EG31 in the mode that coincides with the 1st region R EG11 with the two sides adhesive tape, become the formation shown in Fig. 6 (a), thereby form movement limiting portion P1 at boundary member.For this reason, though flexible substrate from the zone 2 by drawing, can not work by this movement limiting portion P1 tension force to the 1st region R EG11 yet.

Fig. 7 is another example that presentation graphs 5 constitutes.

State before Fig. 7 (a) expression assembling flexible substrate if assembling is in the flexible substrate of the state of Fig. 7 (a), then becomes the shape of Fig. 7 (b).The flexible substrate FR1 of the shape shown in this Fig. 7 (a) together is installed in the basket of mobile device with keeping module 202 by screw.

In the example of Fig. 5, record and the 3rd region R EG3 is set makes the 3rd region R EG3 overlap and folding fixing example with the 1st region R EG1, but in the example of Fig. 7, expression has in the 1st region R EG12 of flexible substrate FR1 and the direct fixedly formation of stiffening plate B2 that bonds of the boundary member between the 2nd region R EG22.Such formation is also passable.
