[0001] The present invention relates to an optical element driving device, a camera module, and a camera-mounted device. [Background technology]

[0002] Conventionally, camera modules mounted on thin camera-mounted devices such as smartphones have been known. Such camera modules are known to include an optical element driving device having an optical element that bends incident light along a predetermined direction in a direction toward an imaging element (see, for example, Patent Document 1).

[0003] The camera module has an optical image stabilization (OIS) function that optically corrects shake (vibration) that occurs during shooting and reduces image distortion by using this optical element driving device to rotate the optical element according to the direction of incident light.

[0004] In the optical element driving device, for example, a movable part that holds an optical element is configured to be movable, and the movable part is driven. A substrate part capable of supplying power to a drive source or the like that drives the movable part is provided on the bottom side of the movable part in the optical element driving device.

[0005] Incidentally, there are cases where some power is supplied inside the movable part. For example, when driving an optical element inside the movable part, it is necessary to supply power to a driving part provided inside the movable part. In this case, a power supply path part is provided that constitutes a power supply path between the substrate part and the movable part. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figures 1A and 1B are diagrams showing a smartphone equipped with a camera module. Figure 2 is a diagram showing a simplified view of a camera module 1 according to an embodiment of the present invention. Figure 3 is a diagram showing a simplified view of a configuration of the camera module 1 according to the present embodiment as viewed from the side.

[0015] The camera module 1 is mounted on a thin camera-mounted device such as a smartphone M (see FIGS. 1A and 1B), a mobile phone, a digital camera, a notebook computer, a tablet terminal, a portable game machine, or an in-vehicle camera.

[0016] In describing the structure of the camera module 1 of this embodiment, a Cartesian coordinate system (X, Y, Z) is used. The same Cartesian coordinate system (X, Y, Z) is used in the figures described later. When an image is actually captured by the camera-mounted device, the camera module 1 is mounted so that the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction, for example. Light from a subject enters from the Z direction + side (plus side), is bent, and is guided to the Y direction + side. By reducing the thickness of the camera module 1 in the Z direction, the camera-mounted device can be made thinner.

[0017] As shown in Figures 2 to 4, the camera module 1 includes a housing 10, a substrate section 20, a cover section 30, a cap section 40 (see Figure 8, etc.), a mirror accommodating section 50, a mirror holding section 60, a power supply path section 70 (see Figure 14, etc.), a drive control section 100, a lens drive section 110, and an imaging section 120.

[0018] The drive control unit 100 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The CPU reads out a program corresponding to the processing contents from the ROM, loads it into the RAM, and centrally controls a first drive unit and a second drive unit described later in cooperation with the loaded program. In this way, the drive control unit 100 drives the mirror housing unit 50 housed in the housing 10 and the mirror holding unit 60 held in the mirror housing unit 50.

[0019] In this embodiment, the mirror accommodating section 50 can be driven to rotate around the Y direction, and the mirror holding section 60 can be driven to rotate around the X direction. Therefore, the mirror element section 61 held by the mirror holding section 60 has a rotation axis extending in the X direction and the Y direction, and rotates around the rotation axis under the control of the drive control section 100. As a result, the camera module 1 has a shake correction function (OIS (Optical Image Stabilization) function) that optically corrects shake (vibration) occurring during shooting to reduce image distortion.

[0020] As shown in FIG. 3, in the camera module 1, incident light L1 along the Z direction (first direction) is incident on the housing 10. The incident light L1 is bent by the mirror element section 61 in the housing 10 so as to proceed to the + side (one side) of the Y direction (second direction). A lens driving section 110 is provided on the + side of the Y direction of the housing 10, and reflected light L2 bent by the mirror element section 61 is incident on the lens driving section 110. The housing 10, the substrate section 20, the cover section 30, the cap section 40, the mirror housing section 50, the mirror holding section 60, and the power supply path section 70 correspond to the "optical element driving device" of the present invention. The housing 10, the substrate section 20, the cover section 30, the cap section 40, the mirror housing section 50, the mirror holding section 60, and the power supply path section 70 will be described later.

[0021] The lens driving unit 110 has, for example, a first fixed lens 111, a first movable lens 112, a second movable lens 113, a second fixed lens 114, and a lens driving control unit 115. In the lens driving unit 110, for example, the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114 are arranged side by side in this order from the negative side (minus side) in the Y direction. The reflected light L2 is output to the imaging unit 120 via the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114.

[0022] The lens drive control unit 115 includes a CPU, a ROM, a RAM, etc., and controls the movement of the first movable lens 112 and the second movable lens 113. In the lens drive unit 110, the first movable lens 112 and the second movable lens 113 move independently in the Y direction under the control of the lens drive control unit 115. This allows the camera module 1 to perform stepless optical zoom and autofocus.

[0023] The imaging unit 120 is disposed on the outer surface on the + side in the Y direction of the lens driving unit 110, and is configured so that reflected light L2 is incident via the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114. The imaging unit 120 has an imaging element, an imaging board, etc. (not shown).

[0024] The imaging element is composed of, for example, a CCD (Charge Coupled Device) type image sensor, a CMOS (Complementary Metal Oxide Semiconductor) type image sensor, etc. The imaging element is mounted on an imaging board and electrically connected to wiring on the board via bonding wires. The imaging element captures a subject image formed by the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114, and outputs an electrical signal corresponding to the subject image.

[0025] A printed circuit board (not shown) is electrically connected to the imaging board of the imaging unit 120, and power is supplied to the imaging element and an electrical signal of the subject image captured by the imaging element is output via this printed circuit board. The electrical signal is output to an imaging control unit 200 provided in the camera-mounted device. The imaging control unit 200 includes a CPU, ROM, RAM, etc., and processes image information obtained by the camera module 1. The imaging control unit 200 may be mounted on the camera-mounted device, but may also be built into the camera module 1.

[0026] Next, the housing 10, the substrate 20, the cover 30, the cap 40 (see FIG. 8, etc.), the mirror housing 50, the mirror holder 60, and the power supply path 70 (see FIG. 14, etc.) will be described in detail. The housing 10, the substrate 20, the cover 30, the cap 40, the mirror housing 50, the mirror holder 60, and the power supply path 70 correspond to the "optical element driving device" of the present invention.

[0027] First, the housing 10 will be described. As shown in Fig. 4, the housing 10 houses the cover portion 30, the cap portion 40, the mirror housing portion 50, the mirror holding portion 60, and the power supply path portion 70, and has, for example, a rectangular parallelepiped shape as a whole. The housing 10 has an entrance wall 11, an exit wall 12, a pair of side walls 13, and a bottom wall 14.

[0028] The incident wall 11 is a wall on the positive side in the Z direction of the housing 10, and is located on the side where the incident light L1 is incident. The incident wall 11 is provided with an opening 11A through which the incident light L1 enters the inside of the housing 10. The opening 11A is located at a position corresponding to the mirror element portion 61 contained in the housing 10. The length of the opening 11A in the Y direction corresponds to the movement range of the mirror in the Y direction (see Figures 28, 29, etc.).

[0029] As a result, even if the positional relationship of the incident light L1 with respect to the opening 11A is shifted due to, for example, vibration during shooting, the mirror element unit 61 moves appropriately under the control of the drive control unit 100, so that the mirror element unit 61 bends the incident light L1 incident through the opening 11A within the range of the opening 12A described later.

[0030] The exit wall 12 is a side wall on the + side in the Y direction of the housing 10, and is located on the side where reflected light L2 emitted when incident light L1 is reflected from the mirror element portion 61. The exit wall 12 is provided with an opening 12A through which the reflected light L2 is output to the outside of the housing 10.

[0031] The opening 12A is formed in a substantially circular shape extending in the X direction. An arc-shaped guide groove portion 12B is provided on the negative surface in the Y direction of the exit wall 12 so as to extend around the rotation axis of the mirror housing portion 50 and along the opening 12A (see FIG. 14). The arc-shaped guide groove portion 12B is configured in an arc shape that is convex toward the positive side in the Z direction, and has a groove shape that tapers toward the bottom (the positive side in the Y direction). By having the arc-shaped guide groove portion 12B, the exit wall 12 supports the mirror housing portion 50 so that the rotation axis is along the Y direction.

[0032] The pair of side walls 13 are side walls on both sides in the X direction of the housing 10, and are configured integrally with the entrance wall 11 and the exit wall 12. As shown in Fig. 5, an engaged portion 13A with which the cover portion 30 engages is provided on an end face on the negative side in the Z direction of the pair of side walls 13.

[0033] The bottom wall 14 is a wall on the negative side in the Z direction of the housing 10. In other words, the bottom wall 14 is disposed on the opposite side in the Z direction to the incident side of the incident light L1 with respect to the mirror housing portion 50. The bottom wall 14 is detachably provided on the negative end faces in the Z direction of the pair of side walls 13. A board portion 20 to which power is supplied from a power source in the camera-mounted device is provided on the bottom wall 14.

[0034] Next, the substrate unit 20 will be described. The substrate unit 20 is disposed along the Y direction away from the mirror housing unit 50, and has a plurality of input / output terminals 21. The substrate unit 20 is configured to be able to input an electric signal from outside the housing 10, or to output an electric signal from inside the housing 10. Of the plurality of input / output terminals 21, an input / output terminal 21A on the + side in the Y direction on the substrate unit 20 is connected to a terminal 12C that enables power supply between the mirror housing unit 50 and the substrate unit 20.

[0035] The terminal 12C is inserted into the emission wall 12 and is provided at a position where it comes into contact with the input / output terminal 21A of the substrate unit 20 when the substrate unit 20 is attached to the pair of side walls 13. The terminal 12C is connected to the mirror accommodating section 50 via the power supply path section 70 (see FIG. 31).

[0036] This enables the substrate 20 to supply power to the mirror housing 50. The substrate 20 has three input / output terminals 21A on each of the positive and negative sides. For example, the positive input / output terminal 21A is disposed on the negative side in the X direction at the end of the substrate 20 on the positive side in the Y direction, and the negative input / output terminal 21A is disposed on the positive side in the X direction at the end of the substrate 20 on the positive side in the Y direction.

[0037] The substrate unit 20 is also provided with a resonating unit 22 constituting a first drive unit for driving the mirror accommodating unit 50 to rotate about a rotation axis (first rotation axis) along the Y direction. As shown in Fig. 6, a contact unit 50A is provided on the negative side of the mirror accommodating unit 50 in the Z direction, which contacts the vibrating resonating unit 22 to apply a preload to the mirror accommodating unit 50 to drive the mirror accommodating unit 50 to rotate.

[0038] The resonator 22 and the contact portion 50A configure an ultrasonic motor that serves as a first drive unit for rotationally driving the mirror housing portion 50 around the Y direction. Note that the first drive unit may be something other than the ultrasonic motor, such as a VCM (Voice Coil Motor).

[0039] Furthermore, a magnet section 50B is provided on the negative side in the Z direction of the mirror housing section 50. The magnet section 50B has a configuration in which an N-pole magnet and an S-pole magnet are adjacent to each other in the X direction.

[0040] 5, a position detector 23 is provided at a position corresponding to the magnet part 50B of the substrate part 20. The position detector 23 is, for example, a magnetoresistance effect element or the like capable of detecting magnetic force, and detects the magnetic force of the magnet part 50B.

[0041] When the mirror housing section 50 is rotated around a rotation axis along the Y direction by the first driving section, the magnetic force of the magnet section 50B detected by the position detection section 23 varies depending on the position of the mirror housing section 50. In other words, the position detection section 23 detects the change in the magnetic force of the magnet section 50B according to the position of the mirror housing section 50, thereby detecting the position of the mirror housing section 50 related to the rotational drive around the Y direction.

[0042] Next, the cover part 30 will be described. As shown in Fig. 6, Fig. 7 and Fig. 8, the cover part 30 is a wall on the negative side in the Y direction of the housing 10, and is configured to be detachable from the negative end parts in the Y direction of the entrance wall 11 and the pair of side walls 13. The cover part 30 has a main body wall part 31, a resin part 32 and a biasing part 33.

[0043] The main body wall portion 31 constitutes the wall surface portion of the cover portion 30 , and is formed in a rectangular shape capable of covering the opening portion formed by the entrance wall 11 and the pair of side walls 13 .

[0044] 9, the resin part 32 is configured in a rectangular frame shape and is fixed to the main body wall part 31 by, for example, being fitted into a rectangular protrusion 31A protruding from the +Y-direction surface of the main body wall part 31. The resin part 32 has a protrusion 32A and an engagement part 32B.

[0045] The protrusions 32A are provided at both ends in the X direction on the positive side in the Z direction of the resin part 32. The protrusions 32A are provided at positions corresponding to the recesses 13B provided in the above-mentioned side wall 13, and fit into the recesses 13B.

[0046] The engaging portion 32B is provided at both ends in the X direction of the negative side in the Z direction of the resin portion 32. The engaging portion 32B is located at a position corresponding to the engaged portion 13A provided at the end of the negative side in the Z direction of the side wall 13 described above, and engages with the engaged portion 13A.

[0047] In this manner, the cover part 30 is attached to the housing 10 by fitting the protruding part 32A into the recessed part 13B and engaging the engaging part 32B with the engaged part 13A.

[0048] The urging portion 33 is a urging member such as a leaf spring, and urges the cap portion 40 toward the mirror accommodating portion 50, thereby urging the mirror accommodating portion 50 toward the + side in the Y direction. The urging portion 33 is fixed to, for example, the main body wall portion 31. As shown in FIG. 10 , the urging portion 33 has an annular portion 331, an arm portion 332, and a connection portion 333.

[0049] The annular portion 331 is located at the center of the biasing portion 33 in the X direction and is configured in an annular shape. The annular portion 331 is a portion that comes into contact with the cap portion 40 and has approximately the same outer shape as the cap portion 40. The annular portion 331 is located at a position corresponding to the cap portion 40 when the cover portion 30 is attached to the housing 10.

[0050] The arm portions 332 extend in the X direction from both ends of the annular portion 331 in the X direction, and two are provided at each end of the annular portion 331 in the X direction. The two arm portions 332 on one side (positive or negative side) in the X direction are connected by a connection portion 333 at an end in the X direction opposite the annular portion 331. When a force is applied to the arm portions 332 to press the annular portion 331 in the Y direction, for example, a restoring force (biasing force) that tries to return the annular portion 331 to its original shape is generated.

[0051] Moreover, the arm portions 332 sandwiching the annular portion 331 in the X direction have shapes symmetrical in the X direction with respect to the annular portion 331. This makes it possible to make the biasing forces from the arm portions 332 on both sides in the X direction uniform in the X direction.

[0052] Furthermore, the two arm portions 332 on one side (positive or negative side) in the X direction have shapes symmetrical with respect to the annular portion 331 in the Z direction. This makes it possible to equalize the biasing forces from the two arm portions 332 in the Z direction.

[0053] Next, the cap portion 40 will be described. As shown in Fig. 11, the cap portion 40 is a portion that covers the first slide groove portion 512A at the end portion on the negative side in the Y direction of the mirror housing portion 50, and is disposed between the mirror housing portion 50 and the cover portion 30 (the biasing portion 33). The cap portion 40 is located at a position corresponding to the annular portion 331 of the biasing portion 33, and is configured in a circular shape similar to the outer shape of the annular portion 331 of the biasing portion 33.

[0054] 12, on the positive side in the Y direction of the cap part 40, i.e., on the side facing the mirror housing part 50, an annular guide groove part 41 is formed so as to extend around the rotation axis of the mirror housing part 50. The annular guide groove part 41 has a groove shape that tapers toward the bottom (the negative side in the Y direction). By having the annular guide groove part 41, the cap part 40 supports the mirror housing part 50 so that the rotation axis is along the Y direction.

[0055] 13, by disposing the cap portion 40 between the mirror housing portion 50 and the cover portion 30, the annular portion 331 of the urging portion 33 is pressed toward the negative side in the Y direction by the cap portion 40. As a result, a urging force (see arrow) that causes the arm portion 332 to return the urging portion 33 to its original shape is generated, and the urging portion 33 urges the cap portion 40 toward the mirror housing portion 50. As a result, the urging portion 33 urges the mirror housing portion 50 toward the positive side in the Y direction.

[0056] Next, the mirror accommodating section 50 will be described. As shown in Fig. 14, the mirror accommodating section 50 is a portion that accommodates the mirror holding section 60 in the camera module 1, and is rotated about a rotation axis along the Y direction by the above-mentioned first driving section. The mirror accommodating section 50 corresponds to the "movable section" of the present invention.

[0057] The mirror accommodating section 50 is configured so that at least the outer shape on the negative side in the Z direction is an arc shape that is convex toward the negative side in the Z direction. This allows the mirror accommodating section 50 to rotate easily around a rotation axis along the Y direction. In addition, the mirror accommodating section 50 is configured so that it can be attached to and detached from the housing 10 through an opening formed by the entrance wall 11 and the pair of side walls 13 of the housing 10 with the cover section 30 removed.

[0058] As shown in Figures 15 and 16, the mirror accommodating section 50 has an accommodating housing 51, a regulating cover section 52, an accommodating side substrate section 53, a first sliding section 54, a first spacing retaining section 55, a second sliding section 56, and a second spacing retaining section 57.

[0059] 17, the accommodating housing 51 is a housing that accommodates the mirror holding part 60, and has a mirror guide part 511, a first sliding wall 512, a second sliding wall 513, a pair of side walls 514, and a pair of yoke parts 515. The accommodating housing 51 has a rectangular outer shape constituted by the first sliding wall 512 and the second sliding wall 513 extending in the X direction, and the pair of side walls 514 extending in the Y direction.

[0060] The mirror guide part 511 is a part that holds the mirror holding part 60 and guides the rotation of the mirror holding part 60 about a rotation axis along the X direction. The mirror guide part 511 is provided on the negative side in the Y direction (first sliding wall 512) of a part of the accommodating housing 51 that is surrounded by the first sliding wall 512, the second sliding wall 513, and the pair of side walls 514.

[0061] The mirror guide part 511 is provided with a rotation guide groove part 511A for guiding the rotation of the mirror holding part 60. The rotation guide groove part 511A configures an arc-shaped guide surface that is convex in an oblique direction toward the negative side in the Z direction and the negative side in the Y direction (see FIG. 19), and is provided with one on each end side in the X direction.

[0062] In addition, a resonating portion 511B serving as a second driving portion is provided between the two rotation guide groove portions 511A. The resonating portion 511B is energized via a terminal 511C electrically connected to the accommodation side substrate portion 53. In addition, a contact portion 50A and a magnet portion 50B serving as the above-mentioned first driving portion are provided on the negative side in the Z direction of the mirror guide portion 511 (see FIG. 6).

[0063] 16 and 18, the first sliding wall 512 is a side wall located on the negative side in the Y direction of the accommodating housing 51, and is a wall that slides against the cap part 40 via the first sliding part 54 and the first spacing part 55 when the mirror accommodating part 50 rotates about the rotation axis along the Y direction. A first sliding groove part 512A is provided in the center of the first sliding wall 512 in the X direction.

[0064] The first slide groove portion 512A is configured in an annular shape, similar to the annular guide groove portion 41 of the above-mentioned cap portion 40. The first slide groove portion 512A is provided at a position facing the annular guide groove portion 41 in the Y direction. The first slide groove portion 512A has a groove shape that tapers toward the bottom (the positive side in the Y direction).

[0065] Further, the first sliding wall 512 is provided with the accommodation side substrate portion 53, and path holders 512B for holding the power supply path portions 70 are provided at both ends in the X direction of the first sliding wall 512. Three path holders 512B are provided at each end in the X direction and configured to be able to hold each of the three power supply path portions 70.

[0066] As shown in Figures 15 and 17, the second sliding wall 513 is a side wall located on the + side of the Y direction in the accommodating housing 51, and is a wall that slides against the above-mentioned exit wall 12 via the second sliding portion 56 and the second spacing retaining portion 57 when the mirror accommodating section 50 rotates around the rotation axis along the Y direction.

[0067] An opening 513A through which reflected light L2 from the mirror element portion is emitted is formed in the second sliding wall 513. The opening 513A is configured in an arc shape that is convex toward the + side in the Z direction, similar to the shape of the above-mentioned opening 12A of the emission wall 12 (see FIG. 14). A second sliding groove portion 513B is provided on the surface of the second sliding wall 513 on the + side in the Y direction, along the opening 513A.

[0068] The second sliding groove portion 513B is configured in an arc shape that is convex toward the + side in the Z direction, similar to the arc-shaped guide groove portion 12B of the above-mentioned emission wall 12 (see FIG. 14). The second sliding groove portion 513B is provided at a position facing the arc-shaped guide groove portion 12B in the Y direction. The second sliding groove portion 513B has a groove shape that tapers toward the bottom (the - side in the Y direction).

[0069] 17, the pair of side walls 514 are provided to sandwich the mirror guide portion 511 in the X direction. Also, as shown in Fig. 19, a restricting portion 514A and a yoke placement portion 514B are provided on the inner surfaces of the pair of side walls 514.

[0070] Since the restricting portion 514A and the yoke mounting portion 514B have substantially the same shape on each of the pair of side walls 514, in the following description, only the + side in the X direction will be described, and a description of the - side in the X direction will be omitted.

[0071] The restricting portion 514A is a portion that restricts the movement of the mirror holding portion 60 based on the rotational drive, and is provided at the end of each side wall 514 on the positive side in the Y direction so as to protrude inward in the X direction from the side wall 514.

[0072] The yoke mounting portion 514B is a portion where each of the pair of yoke portions 515 is disposed, and is provided so as to protrude inward in the X direction from each side wall 514. The yoke mounting portion 514B is configured in an arc shape that protrudes obliquely toward the negative side in the Z direction and the negative side in the Y direction along the above-mentioned mirror guide portion 511, and is provided at a position that protrudes further toward the positive side in the Z direction than the mirror guide portion 511.

[0073] The pair of yoke portions 515 are yokes that form a magnetic circuit together with magnet portion 623, which will be described later, and are disposed on each of yoke arrangement portions 514B of the pair of side walls 514. Yoke portion 515 is configured in an arc shape that is convex in an oblique direction toward the negative side in the Z direction and the negative side in the Y direction along yoke arrangement portion 514B. In other words, yoke portion 515 has first surface 515A that extends parallel to the guide surface (rotation guide groove portion 511A that is the surface on the positive side in the Z direction) of mirror holding portion 60 in mirror guide portion 511 in the X direction and is concentric with the guide surface in the Y direction.

[0074] 15 and 16 , the restricting cover portion 52 is provided in the range between the pair of side walls 514 and the first sliding wall 512, and restricts the mirror holding portion 60 from coming out of the mirror accommodating portion 50. The restricting cover portion 52 has a first restricting portion 521 and a second restricting portion 522.

[0075] The first restricting portion 521 is disposed so as to cover the first sliding wall 512 from the negative side in the Y direction. A portion of the first restricting portion 521 corresponding to the first sliding groove portion 512A is open. This portion has a size large enough to allow the cap portion 40 to pass through.

[0076] A first restriction wall 521A is provided at an end portion on the positive side in the Z direction of the first restriction part 521. The first restriction wall 521A is provided so as to protrude from the end portion toward the positive side in the Y direction. The first restriction wall 521A restricts the movement of the mirror holding part 60 toward the positive side in the Z direction (see FIG. 28).

[0077] The second restricting portion 522 extends from both sides in the X direction of the first restricting portion 521 toward the + side in the Y direction, and is provided so as to be mountable on the pair of side walls 514. The second restricting portion 522 is provided with a second restricting wall 522A extending toward the - side in the Z direction on the inner side of the side wall 514.

[0078] This second restriction wall 522A restricts the movement of the mirror holding part 60 to the + side in the Z direction (see FIGS. 28 and 29).

[0079] 18, the accommodating side substrate portion 53 is configured to be engageable with a protrusion protruding from the first sliding wall 512 to the negative side in the Y direction. The accommodating side substrate portion 53 has a main body substrate portion 531 and an extending substrate portion 532.

[0080] Main body substrate part 531 is configured to extend from path holder 512B on the negative side in the X direction to path holder 512B on the positive side in the X direction. A portion of main body substrate part 531 corresponding to first slide groove part 512A is cut out on the positive side in the Z direction so as not to overlap with first slide groove part 512A.

[0081] First power supply terminals 531A connected to power supply path section 70 are provided at both ends of main body substrate section 531 in the X direction, i.e., at portions corresponding to path holding sections 512B. In this embodiment, three first power supply terminals 531A are provided at each of both ends of main body substrate section 531 in the X direction.

[0082] Further, at the center in the X direction of main body substrate section 531, there is provided second power supply terminal 531B connected to terminal 511C (see FIG. 17) connected to above-mentioned resonance section 511B.

[0083] The extending substrate portion 532 extends from the end portion on the negative side in the X direction of the main substrate portion 531 to the positive side in the Y direction along the side wall 514. On the extending substrate portion 532, a position detection portion 532A is disposed.

[0084] The position detection unit 532A is, for example, a magnetoresistance effect element capable of detecting a magnetic force. As shown in Fig. 17, a position detection hole 514C penetrating in the X direction is formed in the side wall 514 on the positive side in the X direction. The position detection unit 532A is disposed at a position corresponding to the position detection hole 514C. As a result, the position detection unit 532A is disposed so as to be able to face the mirror holding unit 60 inside the accommodating housing 51, and magnetically detects the position of the mirror holding unit 60 (magnet unit 623).

[0085] 16, 20, and 21, the first sliding portion 54 is a spherical member interposed between the annular guide groove portion 41 of the cap portion 40 and the first sliding groove portion 512A of the first sliding wall 512, and constitutes a surface that supports the mirror housing portion 50 by being interposed between the cap portion 40. A total of nine first sliding portions 54 are provided, and are provided in three separate groups of three at three locations on the first sliding groove portion 512A. Of the three first sliding portions 54 arranged side by side, the first sliding portions 54 arranged in the middle are spaced apart from each other by approximately 120 degrees.

[0086] Moreover, among the three first sliding parts 54 arranged side by side, the first sliding part 54 arranged in the middle is configured to have a larger diameter than the other first sliding parts 54. Therefore, the first sliding part 54 arranged in the middle slides between the annular guide groove part 41 and the first sliding groove part 512A (see FIG. 21). That is, the first sliding part 54 is accommodated in the annular guide groove part 41 and the first sliding groove part 512A so as to be slidable in accordance with the rotation of the mirror accommodating part 50.

[0087] In this way, since the first sliding portion 54 interposed between the cap portion 40 and the first sliding wall 512 is composed of a spherical member, when the mirror accommodating portion 50 rotates around the Y direction, the first sliding portion 54 slides while rolling between the annular guide groove portion 41 and the first sliding groove portion 512A. In other words, the first sliding portion 54 follows the rotation of the mirror accommodating portion 50. This allows the mirror accommodating portion 50 to rotate smoothly around the Y direction.

[0088] In addition, since the cap portion 40 is urged toward the mirror housing portion 50 by the urging portion 33 (annular portion 331) (see FIG. 13), the cap portion 40 functions as a thrust bearing that receives the load in the Y direction (thrust direction) of the mirror housing portion 50 at the end portion on the negative side in the Y direction. This makes it possible to reduce the load applied to the camera module 1 in the Y direction.

[0089] The first spacing portion 55 is a flat plate member that maintains the spacing between the multiple first sliding portions 54, and is disposed between the portion of the first sliding wall 512 that corresponds to the first sliding groove portion 512A and the cap portion 40 so as to be perpendicular to the Y direction. The first spacing portion 55 is configured in a circular shape that corresponds to the portion of the first sliding wall 512 that corresponds to the first sliding groove portion 512A and the cap portion 40.

[0090] The first spacing portion 55 has three holes 55A that allow three first sliding portions 54 to be arranged side by side. Three first sliding portions 54 are arranged in each of the three holes 55A. A portion 551 of the first spacing portion 55 other than the holes 55A divides the annular opening of the first sliding groove portion 512A into a plurality of divided openings, forming a partition portion in which the plurality of first sliding portions 54 are individually arranged. The three holes 55A are arranged at positions corresponding to the plurality of divided openings in the first sliding groove portion 512A. In other words, the first spacing portion 55 is a flat plate member in which the partition portion is formed by the three holes 55A.

[0091] Thereby, when the mirror accommodating section 50 rotates about a rotation axis along the Y direction, the interval between the first sliding parts 54 is maintained so as to be aligned within a predetermined angle range in the rotation direction of the mirror accommodating section 50. As a result, an interval of about 120 degrees is maintained with respect to the rotation center (the center of the first spacing maintaining part 55), so that the arrangement balance between the first sliding parts 54 is improved, and the rotation of the mirror accommodating section 50 can be stabilized.

[0092] Furthermore, since the first spacing portion 55 is formed of a separate member from the first sliding groove portion 512A (housing 51) and the annular guide groove portion 41 (cap portion 40), it is not necessary to remake the housing 51 or the cap portion 40 when adjusting the position of the first sliding portion 54. Specifically, it is only necessary to appropriately adjust the position of the hole 55A of the first spacing portion 55, so that the design (work) man-hours required for adjusting the position of the first sliding portion 54 can be significantly reduced.

[0093] Furthermore, since first spacing portion 55 is formed from a flat plate member, the position of hole 55A can be easily adjusted, and thus the number of design steps can be significantly reduced.

[0094] In addition, in this embodiment, since the first sliding groove portion 512A and the annular guide groove portion 41 are configured to extend in an annular shape, it is possible to collectively accommodate a plurality of first sliding portions 54. Therefore, compared to a configuration in which the position of the first sliding portions is defined within the groove portion, it is easier to arrange each of the first sliding portions 54 within the groove portion, and it is easier to adjust the interval between each of the first sliding portions 54 by the first spacing retaining portion 55.

[0095] Furthermore, since the first spacing portion 55 is made of a flat plate member, it does not take up any width in the Y direction (the emission direction of the reflected light L2), so that the size of the accommodating housing 51 in the Y direction can be reduced.

[0096] Moreover, the first spacing portion 55 is disposed, for example, in a fixed state with respect to the mirror housing portion 50. Specifically, the first spacing portion 55 is fixed to a portion corresponding to the first sliding portion 54 by, for example, an adhesive or the like.

[0097] Therefore, even if a force is generated that causes a deviation in the positional relationship between the first sliding portion 54 and the mirror accommodating portion 50, the first spacing retaining portion 55 is fixed to the mirror accommodating portion 50, so that the positional relationship between the first sliding portion 54 and the mirror accommodating portion 50 is maintained within a certain range (within the range of hole 55A).

[0098] In this embodiment, since the first sliding part 54 is a spherical member, when the mirror housing part 50 rotates about a rotation axis along the Y direction, the first sliding part 54 slides while rolling. Therefore, even if a force that causes the positional relationship between the first sliding part 54 and the mirror housing part 50 to be displaced is generated, the mirror housing part 50 can be rotated smoothly.

[0099] In addition, since the first sliding groove portion 512A has a shape tapered toward the + side in the Y direction and the annular guide groove portion 41 has a shape tapered toward the - side in the Y direction, the first sliding portion 54 can be supported at two points in each groove portion. As a result, the position of the first sliding portion 54 can be easily stabilized in each groove portion.

[0100] 22, 23, and 24, the second sliding portion 56 is a spherical member interposed between the arc-shaped guide groove portion 12B of the emission wall 12 and the second sliding groove portion 513B of the second sliding wall 513, and constitutes a surface that supports the mirror accommodating portion 50 by being interposed between the emission wall 12. A total of three second sliding portions 56 are provided, and are provided separately at three locations in the arc-shaped guide groove portion 12B and the second sliding groove portion 513B. Of the three second sliding portions 56, two adjacent second sliding portions 56 are disposed with a predetermined interval therebetween.

[0101] The predetermined interval is an angle that can be set according to the shape of the arc in the arc-shaped guide groove portion 12B and the second slide groove portion 513B, and is an angle that is at least less than 120 degrees. In this embodiment, it is about 90 degrees (see FIG. 23).

[0102] In this way, since the second sliding portion 56 interposed between the emission wall 12 and the second sliding wall 513 is composed of a spherical member, when the mirror accommodating section 50 rotates around a rotation axis along the Y direction, the second sliding portion 56 slides while rolling between the arc-shaped guide groove portion 12B and the second sliding groove portion 513B. In other words, the second sliding portion 56 is accommodated in the arc-shaped guide groove portion 12B and the second sliding groove portion 513B so as to be slidable in accordance with the rotation of the mirror accommodating section 50, and follows the rotation of the mirror accommodating section 50. This allows the mirror accommodating section 50 to rotate smoothly around the Y direction.

[0103] Second spacing retaining portion 57 is a flat plate member that retains the spacing between the multiple second sliding portions 56, and is disposed between a portion of second sliding wall 513 that corresponds to second sliding groove portion 513B and a portion of emission wall 12 that corresponds to arc-shaped guide groove portion 12B, so as to be perpendicular to the Y direction. Second spacing retaining portion 57 is configured in an arc shape that convex toward the + side in the Z direction, corresponding to the portion that corresponds to second sliding groove portion 513B and the portion that corresponds to arc-shaped guide groove portion 12B.

[0104] The second spacing portion 57 has three holes 57A each large enough to accommodate one second sliding portion 56. A second sliding portion 56 is arranged in each of the three holes 57A. A portion 570 of the second spacing portion 57 other than the holes 57A divides the annular opening of the second sliding groove portion 513B into a plurality of divided openings, forming a partition portion in which the plurality of second sliding portions 56 are individually arranged. The three holes 57A are arranged at positions corresponding to the plurality of divided openings in the second sliding groove portion 513B. In other words, the second spacing portion 57 is a flat member that constitutes a partition portion with the three holes 57A. As a result, the second spacing portion 57 holds the three second sliding portions 56 so that the three second sliding portions 56 are arranged at equal intervals in the rotation direction of the mirror accommodating portion 50.

[0105] Therefore, when the mirror accommodating section 50 rotates about the rotation axis along the Y direction, the intervals between the second sliding parts 56 are maintained so as to be aligned within a predetermined angle range in the rotation direction of the mirror accommodating section 50. As a result, the arrangement balance between the second sliding parts 56 is improved, and the rotation of the mirror accommodating section 50 can be stabilized.

[0106] Moreover, since second spacing portion 57 is formed of a separate member from second sliding groove portion 513B (housing 51) and arc-shaped guide groove portion 12B (emission wall 12), it is not necessary to remake housing 51 or emission wall 12 when adjusting the position of second sliding portion 56. Specifically, it is only necessary to appropriately adjust the position of hole 57A of second spacing portion 57, so that the design (work) man-hours required for adjusting the position of second sliding portion 56 can be significantly reduced.

[0107] Furthermore, since the second spacing portion 57 is made of a flat plate member, the position of the hole 57A can be easily adjusted, and therefore the number of design steps can be significantly reduced.

[0108] In addition, in this embodiment, the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are configured to extend in an arc shape, so that it is possible to collectively accommodate a plurality of second sliding portions 56. Therefore, compared to a configuration in which the position of the second sliding portion is defined within the groove portion, it is easier to arrange each second sliding portion 56 within the groove portion, and it is easier to adjust the interval between each second sliding portion 56 by the second spacing portion 57.

[0109] Furthermore, since the second spacing portion 57 is made of a flat plate member, it does not take up any width in the Y direction (the emission direction of the reflected light L2), so that the size of the accommodating housing 51 in the Y direction can be reduced.

[0110] Further, second spacing portion 57 is disposed in an unfixed state with respect to mirror housing portion 50 and emission wall 12. The unfixed state refers to a state in which second spacing portion 57 is not fixed to any portion with a fastening member such as a screw, and is not adhered, welded, or the like to any portion.

[0111] Therefore, if a force is generated that causes the positional relationship between the second sliding part 56 and the mirror accommodating part 50 to shift, the second sliding part 56 will press against the edge of the hole 57A of the second spacing part 57, and the second spacing part 57 will also follow the movement of the second sliding part 56.

[0112] This stabilizes the position of the second spacing retaining parts 57 between the mirror accommodating part 50 and the emission wall 12, making it easier for the second sliding parts 56 to move to positions that facilitate balance when the mirror accommodating part 50 rotates. In addition, since the second spacing retaining parts 57 also move in the rotational direction, the spacing between the second sliding parts 56 does not fluctuate, and the rotation of the mirror accommodating part 50 can be stabilized.

[0113] In addition, in this embodiment, from the viewpoint of reducing the height of the housing 10, the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are configured to have an arc shape that is convex toward the + side in the Z direction, and the portion on the - side in the Z direction of the circle formed by the arc is cut away. In other words, the rotation center C1 around the Y direction of the mirror housing portion 50 is located on the - side in the Z direction of the center of gravity G of the mirror housing portion 50. Therefore, the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are not formed in a circular shape.

[0114] For this reason, it is necessary to make the intervals between the second sliding parts 56 relatively small. If the second sliding groove part can be configured in a circular shape, the intervals between the three second sliding parts 56 can be set to 120 degrees, and it is easy to balance the arrangement of the second sliding parts 56, so that it is possible to stabilize the rotation of the mirror accommodating part 50.

[0115] In contrast, in this embodiment, the intervals between the second sliding parts 56 tend to be relatively small, so that the second sliding parts 56 tend to be biased toward the + side in the Z direction with respect to the rotation center C1, for example, and there are no second sliding parts 56 on the - side in the Z direction with respect to the rotation center C1. In other words, in this embodiment, it is difficult to balance the arrangement of the second sliding parts 56.

[0116] However, in this embodiment, the second spacing retaining portion 57 prevents the positional relationship between the second sliding portions 56 from being shifted. Therefore, even in a configuration in which it is difficult to balance the arrangement of the second sliding portions 56, it is possible to stabilize the rotation of the mirror accommodating portion 50. As a result, it is possible to achieve a low height for the mirror accommodating portion 50 (accommodating housing 51).

[0117] In this embodiment, the above-mentioned biasing portion 33 biases the mirror accommodating portion 50 toward the + side in the Y direction (the exit wall 12 side). Therefore, the second sliding portions 56 are pressed against the arc-shaped guide groove portion 12B by the biasing force of the biasing portion 33, so that the arrangement balance of the second sliding portions 56 can be easily maintained, and thus the rotation of the mirror accommodating portion 50 can be stabilized.

[0118] As described above, since the second spacing retaining portion 57 follows the movement of the second sliding portions 56, the second sliding portions 56 can freely move to positions where they can easily balance each other according to the rotational position of the mirror housing portion 50 while retaining the spacing between the second sliding portions 56. As a result, the rotation of the mirror housing portion 50 can be stabilized.

[0119] In addition, since the second sliding groove portion 513B is tapered toward the negative side in the Y direction and the arc-shaped guide groove portion 12B is tapered toward the positive side in the Y direction, the second sliding portion 56 can be supported at two points in each groove portion. As a result, the position of the second sliding portion 56 can be easily stabilized in each groove portion.

[0120] Next, the mirror holding part 60 will be described. As shown in Fig. 17, the mirror holding part 60 is a part that holds the mirror element part 61, and is detachably housed in the mirror housing part 50. The mirror holding part 60 is disposed in the mirror guide part 511 in the mirror housing part 50, and is configured to be slidable on the mirror guide part 511. The mirror holding part 60 corresponds to the "optical element holding part" of the present invention.

[0121] As described above, the mirror guide portion 511 is provided with an arc-shaped rotation guide groove portion 511A, and the mirror holding portion 60 is configured to be rotatable about a rotation axis (second rotation axis) along the X direction by sliding along the rotation guide groove portion 511A.

[0122] As shown in FIGS. 25 and 26, the mirror holding portion 60 has a mirror element portion 61, a holding housing 62, a third sliding portion 63, and a holding contact portion 64.

[0123] The mirror element portion 61 includes a mirror element (optical element) capable of reflecting the incident light L1, and is configured in a substantially rectangular shape. Since the rotation guide groove portion 511A has an arc shape that is convex in the oblique direction toward the negative side in the Z direction and the negative side in the Y direction, the mirror holding portion 60 is disposed on the rotation guide groove portion 511A, and is thus disposed at an angle with respect to the Z direction and the Y direction (see FIG. 28, etc.).

[0124] In other words, the mirror element portion 61 is arranged so as to be able to bend the incident light L1 so as to travel toward one side (the positive side) in a direction (the Y direction) different from the direction along the incident light L1 (the Z direction). The mirror element portion 61 corresponds to the "optical element portion" of the present invention.

[0125] As shown in FIG. 25, holding housing 62 is a part that holds mirror element section 61 and slides along mirror guide section 511 , and has a main body section 621 and a magnet holding section 622 .

[0126] The main body 621 is a portion for fixing the mirror element unit 61, and has a fixing surface 621A to which the mirror element unit 61 can be fixed. The main body 621 is disposed in the mirror guide unit 511 so that the fixing surface 621A faces the + side in the Z direction. The mirror element unit 61 is adhesively fixed to the fixing surface 621A, for example, with an adhesive. The mirror element unit 61 may be fixed to the main body 621 in any manner.

[0127] 26, a third sliding groove 621B is provided on a surface of the main body 621 facing the negative side in the Z direction. The third sliding groove 621B is configured in an arc shape that convex toward the negative side in the Z direction so that it can be arranged along the above-mentioned rotation guide groove 511A. The third sliding groove 621B has an arc length shorter than that of the rotation guide groove 511A (guide surface) of the mirror guide 511, and serves as a guided surface that is guided by the rotation guide groove 511A.

[0128] The third sliding groove portion 621B is provided at each of both ends in the X direction of the main body portion 621, and is provided at a position facing the rotation guide groove portion 511A in the Z direction (see FIG. 27). The third sliding groove portion 621B has a groove shape that tapers toward the bottom (the positive side in the Z direction).

[0129] The third sliding portion 63 is a spherical member interposed between the rotation guide groove portion 511A and the third sliding groove portion 621B. Three third sliding portions 63 are provided on each of both ends in the X direction. The three third sliding portions 63 on one side (positive side or negative side) in the X direction are arranged side by side along the groove shape of the third sliding groove portion 621B.

[0130] In this way, since the third sliding portion 63 interposed between the rotation guide groove portion 511A and the third sliding groove portion 621B is composed of a spherical member, when the mirror holding portion 60 rotates around the rotation axis along the X direction, the third sliding portion 63 slides while rolling between the rotation guide groove portion 511A and the third sliding groove portion 621B (see FIG. 27). This allows the mirror holding portion 60 to rotate smoothly around the rotation axis along the X direction.

[0131] Further, a holding contact portion 64 is attached to a surface of the main body portion 621 facing the negative side in the Z direction. The holding contact portion 64 is provided between the third sliding groove portions 621B at both ends in the X direction, and is disposed at a position where it can come into contact with the resonating portion 511B of the mirror guide portion 511 described above (see FIG. 17). The holding contact portion 64 applies a preload to the mirror holding portion 60 to rotate the mirror holding portion 60 by coming into contact with the vibrating resonating portion 511B.

[0132] That is, the resonating portion 511B and the holding contact portion 64 constitute an ultrasonic motor that serves as a driving portion (second driving portion) that drives the mirror holding portion 60 to rotate around the X direction, that is, to move the mirror holding portion 60 on the mirror guide portion 511. Note that the second driving portion may be something other than the ultrasonic motor, such as a VCM.

[0133] 28, when the mirror holding part 60 rotates to the maximum extent toward the + side in the Z direction, the end of the main body part 621 on the + side in the Z direction moves to a position where it faces the above-mentioned restricting cover part 52 and does not come into contact with the first restricting wall 521A (see the dashed line). Due to the existence of the first restricting wall 521A, even if the main body part 621 moves excessively or an external force is applied that moves it toward the + side in the Z direction, it is possible to restrict the movement of the main body part 621 toward the + side in the Z direction.

[0134] As shown in FIGS. 25 and 26, magnet holders 622 are provided on both ends in the X direction of main body 621, and protrude from each of the ends to the + side in the Z direction and to the + side in the Y direction.

[0135] 28 and 29, the magnet holding portion 622 is disposed at a position facing the second restriction wall 522A of the above-mentioned restriction cover portion 52 in the Z direction. The amount of protrusion of the magnet holding portion 622 toward the + side in the Z direction is such that it does not come into contact with the second restriction wall 522A. Due to the presence of the second restriction wall 522A, even if an external force is applied to the main body portion 621 to move it toward the + side in the Z direction, the movement of the main body portion 621 toward the + side in the Z direction can be restricted.

[0136] 29, the magnet holding part 622 faces the restricting part 514A of the side wall 514 in the Y direction, and when the mirror holding part 60 rotates to the maximum extent toward the + side in the Y direction, the end part on the + side in the Y direction moves to a position where it does not come into contact with the restricting part 514A (see dashed line). Due to the presence of the restricting part 514A, even if the mirror holding part 60 moves excessively or an external force is applied that moves it toward the + side in the Y direction, it is possible to restrict the movement of the mirror holding part 60 toward the + side in the Y direction.

[0137] 25 and 26, the magnet holder 622 is provided with a magnet section 623. The magnet section 623 has a first pole 623A and a second pole 623B arranged adjacent to each other in the Y direction. The first pole 623A is a magnet with an S pole, and the second pole 623B is a magnet with an N pole.

[0138] 30, a portion of magnet holding section 622 that holds magnet section 623 is provided at a position facing yoke arrangement section 514B of accommodating housing 51 described above in the Z direction. Magnet holding section 622 has a shape in which a surface on the negative side in the Z direction follows yoke arrangement section 514B (yoke section 515). Specifically, magnet holding section 622 is movable along first surface 515A of yoke section 515 as mirror holding section 60 moves, and has second surface 623C having the same curvature as first surface 515A (rotation guide groove section 511A).

[0139] Magnet holding portion 622 holds magnet portion 623, whereby magnet portion 623 is disposed opposite yoke portion 515 in yoke mounting portion 514B.

[0140] This magnetically attracts the magnet portion 623 and the yoke portion 515. In other words, the magnet portion 623 and the yoke portion 515 generate a pressure that magnetically attracts the mirror holding portion 60 toward the accommodating housing 51.

[0141] As a result, the mirror holding portion 60 remains attracted to the accommodating housing 51 even when it is rotated or when an external force is applied, so that the mirror element portion 61 can be securely held within the housing 10.

[0142] 28 and 29, in this embodiment, from the viewpoint of simplifying and reducing the height of the housing 10, the curved shape formed by the rotation guide groove portion 511A and the third sliding groove portion 621B is set so that the movement amount of the mirror holding part 60 in the Y direction is relatively large and the movement amount of the mirror holding part 60 in the Z direction is relatively small. Therefore, the rotation center C2 of the rotation axis of the mirror holding part 60 in this embodiment is located outside the accommodation housing 51.

[0143] To achieve this, the mirror holding part 60 is arranged in a state where it does not have a fixed point on the accommodating housing 51, or where it has a relatively simple holding point or engagement point. In this embodiment, the mirror holding part 60 is arranged in a state where it does not have a fixed point on the accommodating housing 51.

[0144] In other words, when the housing 10 is simplified and made lower in height, the movement mechanism of the mirror holding part 60 must be simplified as well, which makes the holding portion of the mirror holding part 60 (mirror element part 61) vulnerable, and ultimately makes the mirror holding part 60 more likely to come off the accommodating housing 51.

[0145] In this embodiment, the magnet portion 623 and the yoke portion 515 are magnetically attracted to each other, so that the mirror holding portion 60 can be reliably held in the housing 10. That is, in this embodiment, even if the holding portion of the mirror holding portion 60 is weak, the mirror holding portion 60 can be reliably held in the accommodation housing 51. As a result, in this embodiment, the housing 10 can be simplified and made thinner.

[0146] In this embodiment, a preload is generated at the opposing portion between magnet portion 623 and yoke portion 515, where they are magnetically attracted to each other, so that a preload can be generated only at the opposing portion between rotation guide groove portion 511A and third slide groove portion 621B. In other words, magnet portion 623 and yoke portion 515 can generate a preload toward the outside in the normal direction of rotation guide groove portion 511A at the opposing position between rotation guide groove portion 511A and third slide groove portion 621B, which is displaced as mirror holding portion 60 moves.

[0147] Therefore, in this embodiment, a simple configuration is possible without the need for a part that is constantly biased, such as a biasing member, and the mirror holding portion 60 can be securely held within the accommodating housing 51.

[0148] In addition, because magnet portion 623 slides along first surface 515A of yoke portion 515, magnet portion 623 can move smoothly along first surface 515A of yoke portion 515 even if mirror holding portion 60 moves.

[0149] Furthermore, since first surface 515A of yoke portion 515 and second surface 623C of magnet portion 623 have the same curvature as rotation guide groove portion 511A, movement of magnet portion 623 on yoke portion 515 can be made even smoother.

[0150] Moreover, magnet holding portion 622 is disposed along a pair of side walls 514 of accommodating housing 51. Side wall 514 on the positive side in the X direction is formed with position detection hole 514C described above, and position detection portion 532A described above is provided at a position corresponding to position detection hole 514C.

[0151] 30, the position detection unit 532A is disposed at a position where it can detect the magnetic force of the magnet unit 623, and detects a change in the magnetic position of the magnet unit 623 of the magnet holder 622 based on the movement of the mirror holder 60. In other words, the position detection unit 532A detects the position of the mirror holder 60.

[0152] As a result, the position of the mirror holding unit 60 can be controlled with high precision. Furthermore, in relation to the yoke portion 515, the magnet portion 623 for attracting the mirror holding unit 60 and the accommodating housing 51 to each other can also be used as a magnet for position detection. As a result, there is no need to provide a separate magnet for position detection, so that the number of parts can be reduced and the configuration can be further simplified.

[0153] Next, a description will be given of the power supply path section 70. As shown in Fig. 31, the power supply path section 70 electrically connects the substrate section 20 and the mirror housing section 50, and constitutes a power supply path between the substrate section 20 and the mirror housing section 50.

[0154] The power supply path sections 70 are used, for example, to supply power to the resonator section 511B and the position detector 532A in the mirror housing section 50, and are provided in total of six, three on each of the positive and negative sides. The three power supply path sections 70 on the positive side are, for example, disposed on the negative side in the X direction of the mirror housing section 50, and the three power supply path sections 70 on the negative side are, for example, disposed on the positive side in the X direction of the mirror housing section 50. In other words, the power supply path sections 70 are provided on both ends of the mirror housing section 50 in the X direction perpendicular to each of the Z direction and the Y direction.

[0155] 31 and the like only shows the negative power supply path section 70 in the X direction. The positive power supply path section 70 in the X direction has substantially the same shape as the negative power supply path section 70 in the X direction, and therefore a description thereof will be omitted. Although the terminal 12C is inserted into the emission wall 12, the emission wall 12 is not shown in FIG. 31 and the like, and only the terminal 12C is shown.

[0156] 31 and 32, the power supply path section 70 extends from the end on the + side in the Y direction of the housing 10 where the terminal 12C connected to the input / output terminal 21A of the above-mentioned board section 20 is located, to the end on the - side in the Y direction where the first power supply terminal 531A of the housing-side board section 53 and the path holder 512B of the mirror accommodating section 50 are located. In other words, the power supply path section 70 extends across both ends of the mirror accommodating section 50 in the Y direction, and extends so as to connect the terminal 12C (terminal on the board section 20 side) and the first power supply terminal 531A (terminal on the mirror accommodating section 50 side) that are arranged apart in the Y direction.

[0157] The power supply path portion 70 extends in the Y direction from the above-mentioned terminal 12C connected to the input / output terminal 21A of the substrate portion 20 and is connected to a first power supply terminal 531A of the accommodation side substrate portion 53 of the mirror accommodation portion 50.

[0158] The power supply path portion 70 is configured to partially include a spring portion. Specifically, the power supply path portion 70 is configured with a first wire portion 71A, a first spring portion 72A, a second wire portion 71B, a second spring portion 72B, and a third wire portion 71C.

[0159] The first wire portion 71A and the third wire portion 71C are wire portions located at both ends in the Y direction of the power supply path portion 70, and are connected to the input / output portion (terminal 12C or first power supply terminal 531A) of the substrate portion 20 or the housing-side substrate portion 53 of the mirror housing portion 50. A damper member 73 is provided at the connection portion between the first wire portion 71A and the third wire portion 71C and the input / output portion.

[0160] The first wire portion 71A is connected to the first spring portion 72A and is configured to be shorter than the third wire portion 71C. The third wire portion 71C is connected to the second spring portion 72B.

[0161] The second wire portion 71B connects the first spring portion 72A and the second spring portion 72B, and is configured to be longer than the first wire portion 71A and the third wire portion 71C.

[0162] The first spring portion 72A and the second spring portion 72B are coil portions formed of coil springs. The first spring portion 72A is disposed between the first wire portion 71A and the second wire portion 71B, and the second spring portion 72B is disposed between the second wire portion 71B and the third wire portion 71C. The second spring portion 72B is configured to be longer than the first spring portion 72A.

[0163] The three power supply path sections 70 on one side (positive or negative side) in the X direction are arranged side by side in the Z direction so as not to interfere with each other. Specifically, of the three power supply path sections 70, the spring sections 72A, 72B of two power supply path sections 70 adjacent to each other in the Z direction are arranged so that their positions in the Y direction are different from each other.

[0164] That is, for example, in the power supply path section 70 on the most + side and the most - side in the Z direction, the first wire section 71A is connected to the terminal 12C of the substrate section 20, and the third wire section 71C is connected to the path holder 512B of the mirror housing section 50. In addition, in the power supply path section 70 located in the middle in the Z direction, the third wire section 71C is connected to the terminal 12C of the substrate section 20, and the first wire section 71A is connected to the path holder 512B of the mirror housing section 50.

[0165] Furthermore, a position fixing portion 74 is provided at the center in the Y direction of the three power supply path portions 70 on one side in the X direction. The position fixing portion 74 is for maintaining the relative positions of the three power supply path portions 70 within a certain range. The position fixing portion 74 is configured in a plate shape, and is configured to be engageable with the portions of the second wire portions 71B. The position fixing portion 74 corresponds to the "maintenance portion" of the present invention.

[0166] In addition, in the power supply path section 70 on the most + side and the most - side in the Z direction, damper members 75 are provided at the engaging portions with the position fixing section 74. In the power supply path section 70 in the middle in the Z direction, the engaging portion with the position fixing section 74 is in a free state. Specifically, in the position fixing section 74, a portion 74A corresponding to the power supply path section 70 in the middle in the Z direction is cut out, and the power supply path section 70 in the middle in the Z direction passes through this portion 74A.

[0167] 33 and 34, when the mirror accommodating section 50 rotates about the rotation axis about the Y direction, the first power supply terminal 531A of the mirror accommodating section 50 moves to the + or - side in the Z direction (movement direction). In other words, the mirror accommodating section 50 moves such that the first power supply terminal 531A, which is the connection part of the power supply path section 70, moves toward or away from the substrate section 20.

[0168] 33, the end portion on the negative side in the X direction is rotated to the side where it is raised, and the first power supply terminal 531A on the negative side in the X direction is moved to the positive side in the Z direction. When the mirror housing section 50 rotates to the side where the end portion on the positive side in the X direction is raised, the first power supply terminal 531A on the negative side in the X direction is moved to the negative side in the Z direction.

[0169] 34, after the mirror housing section 50 moves, the first power supply terminal 531A is located on the + side in the Z direction relative to its position before the movement (see FIG. 33). Therefore, after the mirror housing section 50 moves (see FIG. 34), the spring sections 72A and 72B are extended longer than they were before the movement (see FIG. 33).

[0170] In this case, for example, if the substrate and the mirror housing are connected using a leaf spring as a power supply path, the leaf spring has a relatively strong reaction force, which is likely to impede rotation of the mirror housing.

[0171] In contrast, in the present embodiment, the power supply path portion 70 extends in the Y direction, and the spring portions 72A, 72B are constructed from coil springs, so that the spring portions 72A, 72B can be configured to easily expand and contract in response to the rotation of the mirror accommodating portion 50.

[0172] That is, the spring portions 72A and 72B have a relatively low reaction force and can absorb the deviation in the positional relationship between the substrate portion 20 and the mirror accommodating portion 50 before and after the movement, which is caused by the rotation of the mirror accommodating portion 50. As a result, the mirror accommodating portion 50 can rotate smoothly while power is supplied to the accommodating-side substrate portion 53 of the mirror accommodating portion 50.

[0173] Incidentally, in the case where all of the power supply path sections 70 are configured so that the spring sections 72A, 72B are positioned at the same position in the Y direction, when the mirror accommodating section 50 is moved to a position in which the spring sections 72A, 72B are extended, for example, as shown in FIG. 34, the two adjacent power supply path sections 70 tend to approach each other, and the spring sections are therefore more likely to interfere with each other.

[0174] In contrast, in the present embodiment, the positions in the Y direction of the spring portions 72A, 72B of two adjacent power supply path portions 70 in the Z direction among the three power supply path portions 70 are different from each other, so that when the spring portions 72A, 72B are deformed based on expansion and contraction, the spring portions of the two adjacent power supply path portions 70 do not interfere with each other. As a result, it is possible to accurately supply power by the two power supply path portions 70. It is also possible to provide spring portions throughout the entire power supply path portion 70 by configuring the spring portions of the power supply path portion 70 with a reduced winding diameter. In this configuration, the interval between the spring portions of the two adjacent power supply path portions can be widened without changing the interval between the power supply path portions, compared to a configuration in which the winding diameter is not reduced, so that it is possible to suppress interference between the spring portions and to weaken the reaction force compared to a configuration in which the spring portions are partially provided.

[0175] Furthermore, since the power supply path sections 70 can be arranged as close as possible, the arrangement space for the power supply path sections 70 can be reduced, and the mirror accommodating section 50 can be made smaller and thinner.

[0176] Furthermore, by providing the position fixing portion 74, the positional relationship in the Z direction of the three power supply path portions 70 can be maintained within a certain range, thereby further preventing interference between the three power supply path portions 70.

[0177] Furthermore, since the arrangement of the spring parts in the middle power supply path section 70 in the Z direction is different from that of the other two power supply path sections 70, the manner in which the spring parts deform when the mirror accommodating section 50 rotates is different from that of the other two power supply path sections 70. Therefore, if this power supply path section 70 is fixed to the position fixing section 74 in the same way as the other two power supply path sections 70, it will affect the movement of the power supply path section 70 due to the rotation of the mirror accommodating section 50.

[0178] In contrast, in the present embodiment, only the power supply path section 70 in the middle in the Z direction is provided in an unfixed state to the position fixing section 74. As a result, it is possible to suppress the influence of the movement of the power supply path section 70 caused by the rotation of the mirror accommodating section 50 on the other two power supply path sections 70.

[0179] In the above embodiment, the biasing portion 33 is configured to have a symmetrical shape in the Z direction (see Figure 10) such that the arm portion 332 on the + side in the Z direction and the arm portion 332 on the - side in the Z direction have the same shape, but the present invention is not limited to this, and the biasing portion 33 does not have to be configured to have a symmetrical shape in the Z direction.

[0180] 35, the arm portion 332A on the positive side in the Z direction and the arm portion 332B on the negative side in the Z direction in the biasing portion 33 may have different shapes. The arm portion 332A on the positive side in the Z direction has a straight portion A1 and a curved portion A2.

[0181] The straight portion A1 extends from the end of the annular portion 331 on the positive side in the Z direction toward the end of the biasing portion 33 in the X direction. The end of the straight portion A1 extends to the vicinity of the connection portion of the two arm portions 332A, 332B.

[0182] The curved portion A2 curves from the end of the straight portion A1 opposite the annular portion 331 toward the negative side in the Z direction, toward the annular portion 331 in the X direction, and then curves toward the opposite side of the annular portion 331 in the X direction to be connected to the connection portion 333.

[0183] The arm portion 332B on the negative side in the Z direction is curved from a portion of the X-direction end of the annular portion 331 closer to the positive side in the Z direction toward the negative side in the Z direction, and then is curved toward the positive side in the Z direction to be connected to the connection portion 333.

[0184] With such a shape, the biasing force of the biasing portion 33 at a portion on the + side in the Z direction of the rotation center C1 of the mirror housing portion 50 is greater than the biasing force at a portion on the - side in the Z direction of the rotation center C1.

[0185] In the above embodiment, the rotation center C1 of the mirror housing section 50 is located on the negative side in the Z direction from the center of gravity G of the mirror housing section 50, and therefore the negative side portions in the Z direction of the circles constituting the arcs of the second sliding groove section 513B and the arc-shaped guide groove section 12B are cut away. Therefore, in the mirror housing section 50, at the end section (the part of the cap section 40) on the negative side in the Y direction, the load acting on the positive side in the Z direction from the rotation center C1 is greater than the load acting on the negative side in the Z direction from the rotation center C1.

[0186] Therefore, by using the biasing portion 33 shown in Figure 35, the biasing force on the + side in the Z direction relative to the rotation center C1 can be increased, making it easier for the cap portion 40 to receive the load in the Y direction more stably, and ultimately stabilizing the rotation of the mirror accommodating portion 50.

[0187] In addition, in the above embodiment, hole 55A of first spacing portion 55 is large enough to accommodate three first sliding portions 54, but the present invention is not limited to this. For example, as shown in FIG. 36, hole 55A may be large enough to accommodate only one first sliding portion 54.

[0188] The hole 55B of this first spacing portion 55 has a diameter substantially equal to that of one first sliding portion 54, and has a diameter large enough that one first sliding portion 54 can rotate within the hole 55B.

[0189] With this configuration, the first sliding portions 54 can be maintained at equal intervals.

[0190] Further, in the above embodiment, the first spacing retaining portion 55 is fixed to the mirror accommodating portion 50, but the present invention is not limited to this, and the first spacing retaining portion 55 may be arranged in an unfixed state with respect to the mirror accommodating portion 50 and the cap portion 40.

[0191] Moreover, by placing the first spacing portion 55 in an unfixed state as shown in FIG. 36, the first spacing portion 55 can more easily follow the movement of the first sliding portion .

[0192] Further, in the above embodiment, the second spacing retaining portion 57 is arranged in an unfixed state with respect to the mirror accommodating portion 50 and the exit wall 12, but the present invention is not limited to this, and it may be fixed to the mirror accommodating portion 50, for example, as shown in FIG. 37.

[0193] The second spacing portion 57 has an arc portion 571 and a protruding portion 572. The arc portion 571 is configured in an arc shape that protrudes toward the positive side in the Z direction, and is provided at a position corresponding to the second sliding groove portion 513B of the second sliding wall 513. The arc portion 571 is provided with a hole 57A in which the second sliding portion 56 is disposed.

[0194] The overhanging portion 572 is provided so as to overhang from the arc portion 571 toward both ends in the X direction. An engagement hole 57B is provided in the overhanging portion 572. Furthermore, a protrusion 513C that protrudes toward the + side in the Y direction is provided at a position corresponding to the engagement hole 57B at both ends in the X direction of the second sliding wall 513. The engagement hole 57B engages with the protrusion 513C, whereby the second spacing portion 57 is fixed to the mirror accommodating portion 50.

[0195] Moreover, by disposing the second spacing retaining portion 57 in a fixed state, the spacing between the holes 57A may be set to the maximum spacing. The maximum spacing is appropriately set according to the second sliding groove portion 513B. In this way, the spacing (angle) between the second sliding portions 56 can be as close to 120 degrees as possible.

[0196] In addition, in the configuration shown in FIG. 37, the position of the second sliding portion 56 is fixed in conjunction with the fixing of the second spacing retaining portion 57, but the present invention is not limited to this, and the second sliding portion 56 may be configured to be allowed to move.

[0197] For example, as shown in FIG. 38, a hole 57C provided in the second spacing portion 57 (arc portion 571) is formed to have a size large enough to accommodate about three second sliding portions 56, for example.

[0198] Further, in the above embodiment, three holes 57A in which the second sliding portion 56 of the second spacing portion 57 is disposed are provided, but the present invention is not limited to this, and three or more holes may be provided.

[0199] For example, as shown in Fig. 39, five holes 57A are provided in the second spacing portion 57. The holes 57A are spaced equally apart between two adjacent holes 57A in the rotational direction.

[0200] With this configuration, it is possible to appropriately adjust the hole 57A into which the second sliding portion 56 is inserted, and it is also possible to arrange three or more second sliding portions 56 (for example, five to match the holes 57A).

[0201] In addition, in the above embodiment, the first spacing portion and the second spacing portion have holes, but the present invention is not limited to this, and they may also be configured to have a notch in which the sliding portion can be positioned.

[0202] Furthermore, in the above embodiment, each groove portion has a shape that tapers toward the groove portion, but the present invention is not limited to this, and the groove portion does not have to have such a shape.

[0203] In addition, in the above embodiment, each sliding part is configured to be spherical, but the present invention is not limited to this, and any shape may be used as long as it is possible for the sliding part to slide between the movable part and its opposing part.

[0204] In the above embodiment, the yoke portion 515 is disposed on the mirror accommodating portion 50 side, and the magnet portion 623 is disposed on the mirror holding portion 60 side, but the present invention is not limited to this. For example, the magnet portion may be disposed on the mirror accommodating portion side, and the yoke portion may be disposed on the mirror holding portion side.

[0205] In the above embodiment, the shape of the opposing surfaces between yoke portion 515 and magnet portion 623 is matched to the shape of the guide surface in mirror guide portion 511, but the present invention is not limited to this. For example, the shape of the opposing surfaces between the yoke portion and magnet portion may be any shape as long as it does not impede the guiding of the mirror holding portion in the mirror guide portion.

[0206] In addition, in the above embodiment, the magnet portion that generates the pressure that attracts the mirror accommodating portion and the mirror holding portion also serves as a magnet for position detection, but the present invention is not limited to this, and a separate magnet portion for position detection may be provided.

[0207] In addition, in the above embodiment, a third sliding part is interposed between the mirror guide part and the mirror holding part, but the present invention is not limited to this, and as long as the mirror guide part is capable of guiding the mirror holding part, the third sliding part does not have to be interposed.
