FIG. 16 is an explanatory diagram of the shape of the flexible printed circuit board 9 when the movable body 5 rotates around the X axis. FIG. 16 shows the movable body 5, base 20, and flexible printed circuit board 9 viewed from the +X direction. FIG. 17 is an explanatory diagram of the shape of the flexible printed circuit board 9 when the movable body 5 rotates around the Y axis. FIG. 17 shows the movable body 5, the base 20, and the flexible printed circuit board 9 viewed from the +YX direction. FIG. 18 is an explanatory diagram of the shape of the flexible printed circuit board 9 when the movable body 5 rotates around the Z axis. FIG. 18 shows the movable body 5, base 20, and flexible printed circuit board 9 viewed from the +ZX direction.

In this example, the flexible printed circuit board 9 connected to the movable body 5 includes a meandering section 157, a first extending section 158, and a second extending section 159. Therefore, when the movable body 5 rotates around the X-axis, the flexible printed circuit board 9 is easily bent. For example, as shown in FIG. 16, when the movable body 5 rotates around the X-axis in one direction indicated by the arrow, the meandering portion 157 tilts around the X-axis in response to the rotation of the movable body 5. Further, the +X direction end portion of the first extension portion 158 connected by the second extension portion curved substrate portion 159a and the second extension portion substrate portion 159b are bent in the direction toward each other or in the direction in which they are separated from each other. nothing. Furthermore, in response to the bending of the end portion of the first extending portion 158 in the +X direction and the inclination of the meandering portion 157, the first extending portion 158 is bent in a direction inclined with respect to the XZ plane. Thereby, rotation of the movable body 5 around the X-axis can be prevented from being inhibited by the flexible printed circuit board 9.

Furthermore, the flexible printed circuit board 9 connected to the movable body 5 includes a meandering section 157 and a second extending section 159 that is displaceable in the Z-axis direction with respect to the board support section 150. Therefore, when the movable body 5 rotates around the Y axis, the flexible printed circuit board 9 is easily bent. For example, as shown in FIG. 17(a), when the movable body 5 rotates around the Y-axis with the −X direction side rotated in the +Z direction as shown by the arrow, the meandering portion 157 The +Z direction end portions of the portion 157a, the meandering portion first curved substrate portion 157b, and the meandering portion second substrate portion 157c are bent in the direction toward each other, and the −Z direction end portions are bent in the direction away from each other. Further, the second extending portion 159 is bent in the −Z direction more than the substrate support surface 150a to which the third extending portion is fixed. Thereby, rotation of the movable body 5 around the Y-axis can be prevented from being inhibited by the flexible printed circuit board 9. Further, as shown in FIG. 17(b), when the movable body 5 rotates around the Y-axis with the -X direction side rotating in the -Z direction as shown by the arrow, the meandering portion 157 The end portions of the substrate portion 157a, the meandering first curved substrate portion 157b, and the second meandering substrate portion 157c in the −Z direction are bent in a direction toward each other, and the end portions in the +Z direction are bent in a direction away from each other. Further, the second extending portion 159 is bent in the +Z direction on the same plane as the substrate supporting surface 150a to which the third extending portion is fixed, or more than the substrate supporting surface 150a. Thereby, rotation of the movable body 5 around the Y-axis can be prevented from being inhibited by the flexible printed circuit board 9.

Here, the board support part 150 includes a board support surface 150a to which the third extension part is fixed, and the board support surface 150a is parallel to the XY plane, and the edge 150b in the -X direction extends in the Y axis direction. It is extending. As a result, when the movable body 5 rotates around the Y-axis, the third extending portions 161a and 161b curve along the edge 150b of the substrate support surface 150a, so that the second extending portion 159 rotates around the Z-axis. It is easy to displace in the direction.

Moreover, since the flexible printed circuit board 9 connected to the movable body 5 includes the meandering portion 157 and the first extending portion 158, it is easily bent when the movable body 5 rotates around the Z-axis. For example, as shown in FIG. 18, when the movable body 5 rotates around the Z-axis, the -X direction side rotates in the -Y direction as shown by the arrow, the first extension portion 158 rotates in the -X direction. The meandering portion 157 is bent in the +Y direction, and the meandering portion 157 is deformed in response to the bending of the first extension portion 158. Thereby, rotation of the movable body 5 around the Z-axis can be prevented from being inhibited by the flexible printed circuit board 9.

Here, the length dimension of the first extended portion substrate portion 158b in the X-axis direction is longer than the width dimension in the Z-axis direction. Therefore, when the movable body 5 rotates around the X-axis, the first extending portion 158 is easily bent.

Further, in this example, the flexible printed circuit board 9 includes a drawer portion 156 located between the meandering portion 157 and the movable body 5, and the drawer portion 156 is a drawer portion board portion extending in the +X direction along the YZ plane. 156a, and a drawer curved board portion 156b that is curved in the Y-axis direction from the drawer board portion 156a and connected to the meandering portion 157. Therefore, when the movable body 5 rotates around the Z-axis, the meandering portion 157 and the first extending portion 158 are more easily bent.

Furthermore, the flexible printed circuit board 9 includes a routing section 155 that is routed along the outer circumferential surface of the movable body 5 between the camera module and the drawer section 156 and is attached to the outer circumferential surface. In this way, the flexible printed circuit board 9 can be connected to the bottom wall 29 perpendicular to the optical axis L in the movable body 5.

Further, each of the drawer curved board portion 156b, the meandering first curved board portion 157b, the meandering second curved board portion 157d, the first extending curved board portion 158a, and the second extending curved board portion 159a. A shape retaining member 167 for retaining the curved shape is fixed. Therefore, the shape of the flexible printed circuit board 9 can be easily maintained.

Furthermore, in this example, the flexible printed circuit board 9 has a first board part 151 and a second board part 152 arranged in the Y-axis direction, and a first board part 151 and a second board part 152 arranged in the +X direction. A third substrate portion 153 is provided that connects an end portion of the portion 151 in the +X direction and an end portion of the second substrate portion 152 in the +X direction. Thereby, the first substrate portion 151 and the second substrate portion 152 can be connected to the movable body 5. Therefore, the wiring pattern connected to the movable body 5 can be distributed to each of the first board portion 151 and the second board portion 152. As a result, the width dimensions of the first substrate portion 151 and the second substrate portion 152 can be suppressed, so that it is possible to suppress the flexible printed circuit board 9 from interfering with the rotation of the movable body 5.

Moreover, since the first substrate portion 151 and the second substrate portion 152 have a symmetrical shape with respect to a virtual plane parallel to the XZ plane, when the movable body 5 rotates, the first substrate portion 151 and the second substrate portion Portion 152 can be similarly deflected. Therefore, the rotation of the movable body 5 is stabilized. Further, the first substrate portion 151 and the second substrate portion 152 are connected by a third substrate portion 153. Thereby, a connector for connecting to a board of an optical device on which the optical unit 1 with shake correction function is mounted can be provided on the third board portion 153. Therefore, only one connector is required, and the connection work for connecting the flexible printed circuit board 9 to external wiring becomes easy.

Further, in this example, the developed shape of the flexible printed circuit board 9 is a simple shape. Therefore, manufacturing the flexible printed circuit board 9 is easy.

Furthermore, in this example, when the movable body 5 rotates around the X axis, the Y axis, and the Z axis, the flexible printed circuit board 9 tends to bend. Therefore, when rotating the movable body 5, the load caused by the bending of the flexible printed circuit board 9 is small. Therefore, since the load caused by the deflection of the flexible printed circuit board 9 is reduced, the driving force of the shake correction magnetic drive mechanism 10 for rotating the movable body 5 around the X-axis and the Y-axis can be reduced. Furthermore, since the load caused by the bending of the flexible printed circuit board 9 is reduced, the driving force of the rolling correction magnetic drive mechanism 13 for rotating the movable body 5 around the Z-axis can be reduced. Therefore, the power consumption of the shake correction magnetic drive mechanism 10 and the rolling correction magnetic drive mechanism 13 can be kept low.

Further, the third extending portion 161 of the first flexible printed circuit board 181 and the third extending portion 161 of the first flexible printed circuit board 181 are each fixed to the substrate supporting portion 150 of the base 20. Furthermore, the first flexible printed circuit board 181 and the second flexible printed circuit board 182 have a symmetrical shape with respect to a virtual plane parallel to the XZ plane. Be prepared. Here, the second extending portion 159 of the first flexible printed circuit board 181 and the second extending portion 159 of the second flexible printed circuit board 182 are respectively aligned with respect to the Z-axis with respect to the substrate supporting surface 150a of the substrate supporting portion 150. It can be displaced in the direction.

In this way, the first flexible printed circuit board 181 and the second flexible printed circuit board 182 can be connected to the movable body 5, so that the wiring pattern connected to the movable body 5 can be connected to the first flexible printed circuit board 181 and the second flexible printed circuit board 182. It can be distributed to each of the substrates 182. Thereby, the width dimensions of the first flexible printed circuit board 181 and the second flexible printed circuit board 182 can be suppressed, so that it is easy to suppress the flexible printed circuit board 9 from interfering with the rotation of the movable body 5.
