The pitching and yawing of the movable body 14 are corrected by the rotary drive mechanism 18 . In addition, in the present embodiment, the coils 32A and 32B are configured as sheet-like coils as an example. A sheet-like coil has a narrower air core than a wound coil, and it tends to be difficult to form a large member at a position corresponding to the air core.

Correction of pitching and yaw is performed as follows. When the optical unit 10 shakes in either or both of the pitching and yawing directions, a shake detection sensor (gyroscope) (not shown) detects the shake, and based on the result, the rotation drive mechanism 18 is driven. . After that, using a magnetic sensor (Hall element) or the like (not shown), the rotational drive mechanism 18 acts to correct the vibration of the optical unit 10 with high accuracy. That is, currents are supplied to the coils 32A and 32B so as to move the movable body 14 in a direction that cancels out the vibration of the optical unit 10, thereby correcting the vibration.

The optical unit 10 of this embodiment includes a rotation drive mechanism 18 that rotates the movable body 14 with respect to the fixed body 16 about the first axis L1 and the second axis L2 as rotation axes. Rotation in the pitching axial direction and the yawing axial direction is achieved by combining the rotations on the first axis L1 and the second axis L2. Here, the rotation drive mechanism 18 may be arranged at a position other than the side where the first flexible wiring board 51a is arranged in the X-axis direction with respect to the movable body 14, as in this embodiment. preferable. Since the rotation drive mechanism 18 can be arranged on the side where the first flexible wiring board 51a is not formed, the rotation drive mechanism 18, the second flexible wiring board 51b connected to the rotation drive mechanism 18, and the first flexible wiring board 51a can be arranged. This is because the contact between and can be suppressed. Therefore, by adopting such a configuration, the optical unit 10 does not need to be enlarged, and the size of the optical unit 10 can be reduced. Note that the term “rotation” in this specification does not require 360° rotation, and includes the case of swinging in the direction of rotation.

The four corners of the movable body 14 are arranged at two of them facing each other. That is, the first thrust receiving member 20a is fixed to the fixed body 16, and the second thrust receiving member 20b is fixed to the movable body . The rectangular frame-shaped portion of the side cover portion 28b and the rectangular frame-shaped movable body 14 are arranged so that the positions of the four corners are aligned. placed one by one.

The extended portion 27a for the first support portion is provided with a spherical concave surface, and the first thrust receiving member 20a is provided with a spherical convex surface. The extension portion 27a is supported by the first thrust receiving member 20a. Similarly, the second support portion extending portion 27b is provided with a spherical concave surface, and the second thrust receiving member 20b is provided with a spherical convex surface. The support portion extending portion 27b is supported by the second thrust receiving member 20b. Since each of the two first support extension portions 27a and each of the two second support extension portions 27b is pressurized outwardly, the pressurization Thus, each spherical concave surface presses against each corresponding spherical convex surface, and the first support portion extension portion 27a and the second support portion extension portion 27b press the corresponding first thrust receiving member 20a and second thrust receiving member 20a. It is supported by the thrust receiving member 20b.

<Arrangement of movable body with respect to fixed body>
Next, with reference to FIGS. 4 to 8 and 11, the detailed shape of the movable body 14, which is the main part of the optical unit 10 of the present embodiment, will be described in detail from the viewpoint of arrangement with respect to the fixed body 16. .

As shown in FIGS. 6 and 7, the holder frame 22 of the movable body 14 has a rectangular frame shape. 4 and 5, the side cover portion 28b of the fixed body 16 has a rectangular movable body accommodating portion 13 corresponding to the rectangular holder frame 22. As shown in FIGS. The rectangular holder frame 22 is arranged and accommodated in the rectangular movable body accommodating portion 13 so that the four corners thereof are aligned. In addition, the movable body accommodating portion 13 is formed larger than the holder frame 22 in order to allow the movable body 14 to swing with respect to the fixed body 16 .

As shown in FIG. 6, on both sides where the magnets 24A and 24B are mounted on the surfaces 22a and 22b of the holder frame 22 on which the rotation drive mechanism 18 is provided, there are provided outward (in the direction facing the side cover portion 28b) A convex portion 11 is formed to protrude (towards). Further, as shown in FIG. 7, the surfaces 22c and 22d of the holder frame 22 on which the rotation drive mechanism 18 is not provided also have projections projecting outward (in the direction facing the side cover portion 28b). A portion 11 is formed. More specifically, convex portions 11a and 11b are formed on both sides of the rotary drive mechanism 18 on the surfaces 22a and 22b of the movable body 14 on which the rotary drive mechanism 18 is provided. A convex portion 11c is formed.

4 and 5, four inner surfaces 13a of the side cover portion 28b on the side of the movable body housing portion 13 have convex portions when the movable body 14 swings with respect to the fixed body 16. A contact portion 15 for contacting with 11 is provided. Specifically, a contact portion 15a that contacts the convex portion 11a, a contact portion 15b that contacts the convex portion 11b, and a contact portion 15c that contacts the convex portion 11c are provided on the inner surface 13a.

That is, the movable body 14 of the present embodiment has convex portions 11 formed on all surfaces intersecting with the optical axis direction and protruding in the direction in which the movable body 14 and the fixed body 16 face each other. Contact portions 15 capable of coming into contact with the projections 11 are formed on all surfaces intersecting the direction, and projections 15 are formed on both sides of the rotation drive mechanism 18 on the surfaces 22a and 22b of the movable body 14 on which the rotation drive mechanism 18 is provided. 11a and 11b are formed. Thus, in the optical unit 10 of this embodiment, the convex portions 11 projecting in the direction in which the movable body 14 and the fixed body 16 face each other are formed on all the surfaces intersecting the optical axis direction. Since the convex portions 11a and 11b are formed on the surfaces 22a and 22b provided on both sides of the rotation driving mechanism 18, the convex portions 11 can be arranged efficiently, and the optical unit 10 does not become large. The movable range of the movable body 14 with respect to the fixed body 16 can be restricted. In addition, although the movable body 14 of the present embodiment has the rotary drive mechanism 18 formed on two sides, it may be formed on three or four sides.

In the optical unit 10 of this embodiment, the convex portion 11 is formed on the movable body 14 and the contact portion 15 is formed on the fixed body 16. In the present invention, the convex portion 11 is formed on the fixed body 16. , and the contact portion 15 may be formed on the movable body 14 . However, it is preferable that the convex portion 11 is formed on the movable body 14 as in this embodiment. By forming the convex portion 11 on the movable body 14, it is possible to prevent the contact position between the convex portion 11 and the contact portion 15 from shifting. This is because the interval between . Further, when the convex portion 11 is formed on the fixed body 16, if the position of the movable body 14 deviates from the design center, there is a possibility that the contact position with the convex portion may be shifted. Displacement of the contact position can be suppressed.

Here, as shown in FIG. 7, in the optical unit 10 of the present embodiment, on the surfaces 22c and 22d of the movable body 14 on which the rotation drive mechanism 18 is not provided, the convex portion 11c intersects the optical axis direction. It is configured to extend in the direction of For this reason, the optical unit 10 of this embodiment is provided with the convex portion 11c extending in the direction intersecting the optical axis direction, thereby increasing the rigidity.

As shown in FIGS. 6 and 7, each convex portion 11 of this embodiment gradually increases in length in the optical axis direction in the direction in which the movable body 14 and the fixed body 16 face each other. It has a tapered portion 110 that becomes shorter, and a planar facing surface 111 that is provided on the tip side of the tapered portion 110 . Thus, it is preferable that the convex portion 11 has the tapered portion 110 . This is because the rigidity can be increased by forming the convex portion 11 to have a tapered portion 110 .

The opposing surface 111 of each convex portion 11 is in contact with the contact portion 15 . Specifically, the opposing surface 111 a of the convex portion 11 a contacts the contact portion 15 a of the contact portions 15 . Similarly, the opposing surface 111 b of the convex portion 11 b contacts the contact portion 15 b of the contact portions 15 , and the opposing surface 111 c of the convex portion 11 c contacts the contact portion 15 c of the contact portions 15 .

Here, with reference to the schematic diagram of the optical unit 10 of this embodiment shown in FIG. 8 and the schematic diagram of the optical unit 10 of Comparative Example 1 shown in FIG. The movable range of the movable body 14 with respect to the fixed body 16 and the positional relationship between the swing shaft 9 and the facing surface 111 when viewed from the direction intersecting the optical axis direction will be described. 8 and 11, the movable body 14 represented by the solid line is not tilted with respect to the fixed body 16, and the movable body 14 represented by the broken line is tilted relative to the fixed body 16 by the swing axis 9. In FIG. , the movable body 14 and the fixed body 16 are in contact with each other. 8 and 11 are diagrams when viewed from the Y-axis direction (pitching axis direction), but the same can be applied when viewed from the X-axis direction (yawing axis direction).

As is clear from a comparison of FIGS. 8 and 11, in the optical unit 10 of this embodiment shown in FIG. The gap G1 with respect to the body 16 is narrowed, and the swinging range of the movable body 14 with respect to the fixed body 16 is restricted. Therefore, even if the movable body 14 is tilted with respect to the fixed body 16 with respect to the swing axis 9 as in the case of the movable body 14 indicated by the dashed line, the convex portion 11 contacts the contact portion 15, so that the coil 32A is rotated. and 32B and the magnets 24A and 24B can be prevented from contacting each other. On the other hand, in the optical unit 10 of Comparative Example 1 shown in FIG. 11, since the convex portion 11 is not formed on the movable body 14, the gap G2 between the movable body 14 and the fixed body 16 is large. Therefore, when the movable body 14 is tilted with respect to the fixed body 16 with respect to the swing axis 9 as in the case of the movable body 14 indicated by the dashed line, the coils 32A and 32B and the magnets 24A and 24B come into contact with each other. may be lost.

As described above, in the support mechanism 20 of the present embodiment, the movable body 14 is arranged with respect to the fixed body 16 with the pitching axial direction and the yawing axial direction, which are directions intersecting the optical axis direction, as rotation axis directions (swinging motion). It can be pivotally supported (with respect to axis 9). Here, as shown in FIG. 8, the convex portion 11 preferably has a structure in which the swing shaft 9 is positioned within the range of the facing surface 111 in the optical axis direction. In other words, it is preferable that the convex portion 11 has a planar facing surface 111 that faces the contact portion 15 and is arranged at a position including the swing axis 9 in the optical axis direction. Since the planar facing surface 111 is arranged at a position including the swing axis 9 in the optical axis direction, the gap G1 between the convex portion 11 and the contact portion 15 for securing a desired movable range of the movable body 14 is maintained. can be minimized.

8, the length of the opposing surface 111 in the optical axis direction exceeds the position of the swing axis 9 in the optical axis direction when the convex portion 11 and the contact portion 15 are in contact with each other. It is preferable that the length is This is because the movable range of the movable body 14 with respect to the fixed body 16 can be limited even when the movable body 14 is moved to the maximum with respect to the fixed body 16 . It should be noted that "a length that does not exceed the position of the swing axis 9 in the optical axis direction when the convex portion 11 and the contact portion 15 come into contact with each other" means, for example, that the upper end portion of the convex portion 11 on the left side in FIG. When the contact portion 15 comes into contact with the swing shaft 9 , the lower end portion of the convex portion 11 on the right side in FIG. It is a configuration that does not reach the upper side.

FIG. 9 is a perspective view of the movable body 14 of the optical unit 10 of Example 2, and is a view corresponding to FIG. 6 of the optical unit 10 of Example 1. FIG. It should be noted that constituent members common to those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
Note that the optical unit 10 of this embodiment has the same configuration as the optical unit 10 of the first embodiment except for the configuration of the movable body 14 .

As described above, in the optical unit 10 of Example 1, the tapered portion 110 was formed on the convex portion 11 . On the other hand, in the optical unit 10 of this embodiment, as shown in FIG. 9, the convex portion 11 does not have a tapered shape. Each of the projections 11 of this embodiment protrudes in the direction perpendicular to the optical axis direction, and has a planar facing surface 111 that contacts the contact portion 15 at the tip.

[Example 3] (Fig. 10)
Next, the optical unit 10 of Example 3 will be described with reference to FIG. FIG. 10 is a perspective view of the movable body 14 of the optical unit 10 of Example 3, and is a view corresponding to FIG. 6 of the optical unit 10 of Example 1. FIG. Components common to those of the first and second embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.
Note that the optical unit 10 of this embodiment has the same configuration as the optical unit 10 of the first embodiment except for the configuration of the movable body 14 .

As described above, in the optical units 10 of Examples 1 and 2, the planar facing surface 111 was formed on the convex portion 11 . On the other hand, in the optical unit 10 of this embodiment, a curved facing surface 111 is formed. More specifically, the support mechanism 20 of this embodiment is configured to support the movable body 14 with respect to the fixed body 16 so as to be able to swing on the basis of the swing shaft 9 in the direction intersecting the optical axis direction. The portion 11 has a facing surface 111 which is an arcuate surface centered on the swing axis 9 . Since the convex portion 11 has an arcuate surface centered on the swing axis 9, the movable range of the movable body 14 can be restricted regardless of the swing angle. It should be noted that the term “arc surface” means either a spherical surface in a spherical shape or a circumferential surface in a columnar shape.
