In the manufacturing process of the optical unit, when the movable body to which the flexible substrate is connected is incorporated into the fixed body, the flexible substrate is bent in a U-shape to perform initial tilt correction and offset correction of the camera. , the movable body assumes a regular posture without being tilted.

However, the flexible wiring board may have variations in its physical properties. In such a case, after the initial tilt correction, the offset correction, and the like are performed to adjust the posture of the movable body, the movable body may be tilted and unable to maintain the normal posture. When the movable body is tilted in this way, the optical axis of the lens, the imaging element, etc. provided on the movable body deviates from the normal position, which causes a problem that a high-definition captured image cannot be obtained. do.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an optical unit that facilitates adjusting the posture of a movable body having an optical module to a normal posture.

In order to achieve the above object, the present invention provides a movable body having an optical module, a fixed body that accommodates the movable body therein, and a rocking support that supports the movable body to rockably with respect to the fixed body.

The adjusting mechanism includes a projecting portion provided on a mounting surface of the fixed body on which the flexible wiring board is mounted, and a projecting portion formed at an intermediate position in the extending direction of the flexible wiring board. A hole portion that engages and has a dimension larger than the projecting portion, an operation portion that extends from the flexible wiring board in a direction perpendicular to the extending direction of the flexible wiring board, and an opening formed on the side surface of the fixed body. and an open portion facing the tip portion of the operating portion.

According to the optical unit of the present invention, in the assembled state of the optical unit, if the movable body is tilted out of the normal posture, the opening formed on the side surface of the fixed body is opened to the movable body. The attachment position and orientation of the flexible wiring board can be adjusted by operating the operation portion of the flexible wiring board. As a result, it is possible to easily adjust the posture of the movable body to a regular posture while suppressing the influence of variations in the characteristics of the flexible wiring substrate. Even if another component is arranged on the side of the optical unit opposite to the object, since the fixing position and orientation of the flexible wiring board can be adjusted from the side surface of the fixed body, after the movable body is incorporated into the fixed body, The origin position (initial tilt position) of the movable body can be adjusted.
After such adjustment is made, if the projecting portion protruding from the mounting surface of the fixed body and the flexible wiring board are fixed with an adhesive or the like, the posture of the movable body may be lost after the adjustment. There is no

Further, in the optical unit, it is preferable that the hole is an elongated hole elongated in the extending direction of the flexible wiring board, and the width of the elongated hole is the same as that of the protrusion.

According to the above configuration, in correcting the posture of the movable body, the flexible wiring board is slidable along the elongated hole in the extending direction thereof, and is centered on the projecting portion provided on the fixed body side. Since it is rotatable, the inclination of the movable body can be easily corrected by operating the operation portion of the flexible wiring board from the outside of the fixed body.
In this case, since the movement of the flexible wiring board in the direction perpendicular to its extending direction is restricted by the protrusion, the movement of the flexible wiring board necessary for adjusting the origin position of the movable body is not required.

Moreover, in the optical unit, it is preferable that the opening has a stepped portion, and that a part of the operating portion of the flexible wiring board is inserted into the opening.

According to the above configuration, the stepped portion formed in the opening portion can be used as a bridging portion when the flexible wiring board is adhered and fixed after the adjustment work is completed. It can be fixed well and securely.

Further, in the optical unit, it is preferable that the adjustment mechanism is arranged at a position where the radius of curvature of the curved portion of the flexible wiring board is within an allowable range.
Here, "within an allowable range" means a range in which the flexible wiring board is unlikely to develop a tendency to bend when it is left standing in that bent state.

According to the above configuration, it is possible to reduce the size of the optical unit by keeping the storage space of the flexible wiring board of the fixed body small.

Further, in the optical unit, it is preferable that a part of the flexible wiring board is bifurcated by a slit elongated in the extending direction.

More specifically, as shown in FIGS. 3 and 4, the protruding portion 22c extends downward (see FIG. 3 and upward in FIG. 4). The hole portion 14a formed in the horizontal portion 14A of the flexible wiring board 14 is formed in the middle position of the horizontal portion 14A of the flexible wiring substrate 14 in the extending direction.
Here, the hole portion 14a is an elongated hole elongated in the extending direction of the flexible wiring board 14 (vertical direction in FIG. 7). It is set to the same dimension as d (b=d).

Further, as described above (see FIG. 5), the width dimension B1 of the open portion 22C is set larger than the width dimension B2 of the operation portion 14B of the flexible wiring board 14 (B1>B2).

Therefore, in adjusting the posture of the movable body 20, the flexible wiring board 14 is slidable along the directions of arrows y1 and y2 in FIG. It is rotatable in the directions of arrows m1 and m2 in FIG. Therefore, by operating the operation portion 14B of the flexible wiring board 14 from the outside of the fixed body 20, the movable body 10 can be held in a normal posture and its inclination can be corrected.
In this case, the movement of the flexible wiring board 14 in the direction perpendicular to its extending direction is restricted by the engagement between the hole 14a and the projection 22c. The origin position of the movable body 10 can be adjusted with high accuracy by operating the flexible wiring board 14 from the outside of the fixed body 20 while allowing the movement (sliding) of the flexible wiring board 14 .

In this case, as described above (see FIG. 6), the stepped portion 22C1 is formed in each of the open portions 22C (only one of which is shown in FIG. 6). It can be used as a bridging portion when the substrate 14 is adhered and fixed with an adhesive. Therefore, the flexible wiring board 14 can be reliably fixed with good workability.
It should be noted that the flexible wiring board 14 after adjustment may be fixed not only with an adhesive, but also with screws or the like.

Further, in the optical unit 1 according to this embodiment, as described above (see FIG. 2), the adjustment mechanism 50 is arranged at a position where the radius of curvature of the curved portion 14C of the flexible wiring board 14 is within the allowable range. As a result, the storage space of the flexible wiring board 14 in the fixed body 20 (second case 22) can be kept small, and the size of the optical unit 1 can be reduced.
2, the radius of curvature of the curved portion 14C of the flexible wiring board 14 is increased, and the fixed body 20 (second 2), the vertical and horizontal dimensions of the case 22) increase, and the optical unit 1 becomes large.

Furthermore, in the optical unit 1 according to the present embodiment, as described above (see FIGS. 3 and 7), the flexible wiring board 14 is partially bifurcated by the long slit 14b in its extending direction. there is As a result, the rigidity in the direction perpendicular to the extending direction of the flexible wiring board 14 (horizontal direction in FIG. 7) is lowered by the slits 14b, making it easier to bend in that direction. As a result, the movable body 10 can be easily moved in the direction perpendicular to the extending direction of the flexible wiring 14, and the adjustment work of the movable body 10 can be facilitated.
