Hereinafter, embodiments of the present utility model will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.

In this specification, for ease of understanding, the first direction X, the second direction Y, and the third direction Z intersecting each other are appropriately described. In the present specification, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other, but may not be orthogonal to each other. One side in the first direction is referred to as one side X1 in the first direction X, and the other side in the first direction is referred to as the other side X2 in the first direction X. One side in the second direction is referred to as one side Y1 in the second direction Y, and the other side in the second direction is referred to as the other side Y2 in the second direction Y. One side in the third direction is referred to as one side Z1 in the third direction Z, and the other side in the third direction is referred to as the other side Z2 in the third direction Z. For convenience, the first direction X may be described as the vertical direction. One side X1 of the first direction X represents a downward direction, and the other side X2 of the first direction X represents an upward direction. However, the vertical direction, the upward direction, and the downward direction are determined for convenience of explanation, and do not need to coincide with the vertical direction. The vertical direction is defined for convenience of description only, and does not limit the orientation of the optical unit 1 of the present utility model when in use or when assembled.

In the present specification, "parallel" includes not only a state where any one of the azimuth, the line, and the plane and any other one of the azimuth, the line, and the plane are completely disjoint, but also a substantially parallel state. In addition, "perpendicular" and "orthogonal" include not only a state in which both intersect each other at 90 degrees, but also a substantially perpendicular state and a substantially orthogonal state, respectively. That is, the terms "parallel", "perpendicular" and "orthogonal" may include a state in which the positional relationship of the two is angularly offset to such an extent that the effects of the present utility model are exhibited.

First, an example of the application of the optical unit 1 will be described with reference to fig. 1. Fig. 1 is a perspective view schematically showing a smartphone 200 provided with an optical unit 1 according to an embodiment of the present utility model. The smartphone 200 has an optical unit 1. The optical unit 1 reflects the incident light in a specific direction. As shown in fig. 1, the optical unit 1 is suitable for use as an optical component of, for example, a smartphone 200. The use of the optical unit 1 is not limited to the smartphone 200, and can be used in various devices such as a digital camera and a video camera.

The smartphone 200 has a lens 202 into which light is incident. In the smartphone 200, the optical unit 1 is disposed further inside than the lens 202. When light L is incident into the inside of the smartphone 200 via the lens 202, the traveling direction of the light L is changed by the optical unit 1. Then, the light L is captured by a capturing element (not shown) via a lens unit (not shown).

Next, the optical unit 1 will be described with reference to fig. 2 to 5. Fig. 2 is a perspective view showing the optical unit 1 according to the present embodiment. Fig. 3 is an exploded perspective view of the optical unit 1 according to the present embodiment, in which the movable portion 2 and the fixed portion 3 are separated. Fig. 4 is an exploded perspective view of the movable portion 2 of the optical unit 1 of the present embodiment. Fig. 5 is an exploded perspective view of the fixing portion 3 of the optical unit 1 of the present embodiment.

As shown in fig. 2 and 3, the optical unit 1 includes at least a movable portion 2, a fixed portion 3, a swinging mechanism 5, and a supporting mechanism 7.

The movable portion 2 is supported by the fixed portion 3. The movable portion 2 has an optical element 10.

As shown in fig. 4, the optical element 10 changes the traveling direction of light. The optical element 10 reflects light L traveling toward one side X1 of the first direction X toward one side Y1 of the second direction Y intersecting the first direction X. The optical element 10 is constituted by a prism. The prism is formed of a transparent material having a higher refractive index than air. The optical element 10 may be, for example, a plate-like mirror. In the present embodiment, the optical element 10 has a substantially triangular prism shape.

Specifically, the optical element 10 includes a light incident surface 11, a light emitting surface 12, a reflecting surface 13, and a pair of side surfaces 14. The light L enters the light incident surface 11. The light emitting surface 12 is connected to the light incident surface 11. The light emitting surface 12 is arranged perpendicular to the light incident surface 11. The reflecting surface 13 is connected to the light incident surface 11 and the light emitting surface 12. The reflecting surfaces 13 are inclined at about 45 degrees with respect to the light incident surface 11 and the light emitting surface 12, respectively. The reflection surface 13 reflects the light L traveling toward one side X1 of the first direction X toward one side Y1 of the second direction Y intersecting the first direction X. That is, the optical element 10 reflects the light L traveling toward one side X1 of the first direction X toward one side Y1 of the second direction Y intersecting the first direction X. The pair of side surfaces 14 are connected to the light incident surface 11, the light emitting surface 12, and the reflecting surface 13.

The fixed portion 3 swingably supports the movable portion 2. The fixed portion 3 supports the movable portion 2 swingably about the swing axis A2. Specifically, the fixed portion 3 swingably supports the movable portion 2 via the support mechanism 7. The fixing portion 3 has a base plate portion 80 and a housing portion 60.

The base plate portion 80 is provided with a coil 52 for swinging the movable portion 2. Specifically, the coil 52 is disposed on one side Y1 of the substrate portion 80 in the second direction Y. The substrate 80 supplies power to the coil 52 at a predetermined timing. The substrate portion 80 is made of, for example, a polyimide substrate. The substrate portion 80 has flexibility. Specifically, the substrate portion 80 is FPC (Flexible Printed Circuit).

The accommodation portion 60 accommodates at least a part of the substrate portion 80. That is, the substrate portion 80 is located inside the accommodating portion 60. In other words, the accommodating portion 60 covers the other side Y2 of the second direction Y of the substrate portion 80. The movable portion 2 is located inside the housing portion 60. That is, the accommodating portion 60 indirectly supports the optical element 10 via the movable portion 2.

The housing portion 60 of the present embodiment has a first positioning portion 65. The first positioning portion 65 determines the position of the substrate portion 80. The first positioning portion 65 is located inside the accommodating portion 60. The first positioning portion 65 determines the position of the substrate portion 80 in two directions along a direction intersecting the thickness direction of the substrate portion 80. Therefore, the position of the substrate portion 80 can be suppressed from changing relative to the housing portion 60. As a result, the substrate portion 80 can be fixed to the housing portion 60 with high accuracy. In addition, for example, even if an impact is applied to the optical unit 1, since the substrate portion 80 is located at the first positioning portion 65, a change in the position of the substrate portion 80 with respect to the housing portion 60 can be suppressed. The substrate portion 80 may be arranged in the housing portion 60 with the first positioning portion 65 as a mark. This allows the substrate 80 to be mounted accurately.

The first positioning portion 65 of the present embodiment is a recess. That is, the substrate portion 80 is accommodated in the recess. Therefore, the movement of the base plate portion 80 is restricted by the recess. As a result, the substrate portion 80 can be fixed to the housing portion 60 with higher accuracy.

In addition, the position of the coil 52 can be suppressed from changing from the position desired by the designer due to the position change of the substrate 80. That is, the swinging function of the movable portion 2 can be made to be a performance desired by the designer. Therefore, when manufacturing a plurality of optical units 1, it is possible to suppress occurrence of variation in the swinging function of the movable portion 2 for each optical unit 1 due to errors in manufacturing.

In addition, the operator who manufactures the optical unit 1 can position the substrate portion 80 inside the housing portion 60 with the first positioning portion 65 as a mark. That is, the first positioning portion 65 can prompt the operator to position the substrate portion 80 inside the accommodating portion 60.

As shown in fig. 3, the housing portion 60 supports the movable portion 2 so as to be swingable about a swing axis A2 intersecting the swing axis A1. Further, the housing portion 60 supports the movable portion 2 in the first direction X. Accordingly, the positional change of the optical element 10 in the first direction X can be suppressed, and therefore the positional change of the reflected light (light L emitted from the optical element 10) in the first direction X can be suppressed.

As shown in fig. 5, the housing portion 60 has a recess H1. The recess H1 may be a recess or a through hole, for example. In the present embodiment, the recess H1 is a rectangular through hole.

The swinging mechanism 5 swings the movable portion 2. As shown in fig. 2 and 3, the swinging mechanism 5 includes a magnet 51, a coil 52, and a magnetic body 84.

The magnet 51 faces the coil 52. The magnet 51 is disposed in the movable portion 2. The magnet 51 and the magnetic body 84 attract each other.

The magnetic body 84 faces the magnet 51. In a state where the coil 52 is not energized, attractive force is generated between the magnet 51 and the magnetic body 84. Thus, the movable portion 2 is disposed at the reference position in the rotation direction around the swing axis A1 and in the rotation direction around the swing axis A2. The magnetic body 84 is disposed in the recess of the housing 60. That is, the housing portion 60 has a concave portion in which the magnetic body 84 is disposed.

The coil 52 is opposed to the magnet 51. The coil 52 is disposed in the fixing portion 3. Therefore, a magnetic field generated when a current flows through the coil 52 acts strongly on the magnet 51. Then, the movable portion 2 swings with respect to the fixed portion 3. This allows the movable portion 2 to swing with a simple configuration using the magnet 51 and the coil 52. In the present embodiment, the magnet 51 is disposed in the movable portion 2. The coil 52 is disposed in the fixing portion 3. By disposing the coil 52 in the fixed portion 3, the coil 52 does not swing with respect to the fixed portion 3. Therefore, the coil 52 can be easily wired, as compared with a case where the coil 52 is arranged in the movable portion 2, for example.

The coil 52 faces the magnetic body 84. In the present embodiment, the coil 52 is located between the magnet 51 and the magnetic body 84. Movement of the magnetic body 84 disposed in the recess H1 of the accommodating portion 60 in the first direction X and movement of the magnetic body in the second direction Y are suppressed. Therefore, misalignment of the magnetic body 84 can be suppressed. As a result, even if the movable portion 2 swings in the rotation direction around the swing axis A1 and the rotation direction around the swing axis A2, the movable portion 2 can be returned to the reference position with high accuracy.

The support mechanism 7 supports the movable portion 2. The support mechanism 7 swingably supports the movable portion 2. The supporting mechanism 7 is located between the movable portion 2 and the fixed portion 3. The supporting mechanism 7 will be described later with reference to fig. 5.

The optical unit 1 will be described in more detail with reference to fig. 2 to 5. As shown in fig. 4, the movable portion 2 further includes a holder 20, a support 30, and a pre-pressing portion 40.

The holder 20 holds the optical element 10. The holder 20 is made of, for example, resin. The holder 20 has a holder body 21 and a pair of side surfaces 22.

The holder body 21 extends in the third direction Z. The holder body 21 supports the optical element 10. The holder body 21 faces the reflection surface 13 of the optical element 10 and is connected to a pair of side surfaces 22. The holder body 21 is an inclined surface inclined at about 45 degrees with respect to the incident direction of the light L, and contacts the reflection surface 13 of the optical element 10 over substantially the entire area of the inclined surface. The incident direction of the light L is a direction toward one side X1 of the first direction X.

The pair of side portions 22 extend from the holder body 21 in a crossing direction crossing the third direction Z. The intersecting direction includes, for example, a first direction X and a second direction Y. The pair of side surfaces 22 are disposed at both ends of the holder body 21 in the third direction Z. The pair of side portions 22 have mutually symmetrical shapes in the third direction Z. The side surface portion 22 includes an opposite side surface 22a, an on-axis recess 22b, and a restricting recess 22c.

The opposite side surfaces 22a are arranged on each of the pair of side surfaces 22. The opposed side surface 22a is opposed to the pre-pressing portion 40.

The shaft concave portion 22b is disposed on the opposite side surface 22a. The shaft concave portion 22b is recessed toward the inside of the holder 20 on the swing axis A1. The on-axis concave portion 22b accommodates at least a part of the on-axis convex portion 45 of the pre-pressing portion 40. The on-shaft recess 22b has at least a part of a concave spherical surface.

The restricting concave portion 22c restricts the movement of the pre-pressing portion 40 along the side surface portion 22 by a predetermined distance or more. More specifically, the restricting recess 22c is recessed toward the inside of the holder 20 in the third direction Z. In the present embodiment, four restricting recesses 22c are provided, for example. The number of the limiting recesses 22c may be one, but is preferably plural.

The support body 30 supports the holder 20. Specifically, as shown in fig. 2, the support body 30 can support the holder 20 holding the optical element 10 so as to swing around a swing axis A1 intersecting the swing axis A2. The swing axis A1 is an axis extending along a third direction Z intersecting the first direction X and the second direction Y. The support body 30 is supported by the fixing portion 3 so as to be swingable about the swing axis A2. The swing axis A2 is an axis extending in the first direction X.

That is, the holder 20 can swing with respect to the support body 30, and the support body 30 can swing with respect to the housing portion 60. Accordingly, since the optical element 10 can be swung about the swing axis A1 and the swing axis A2, the posture of the optical element 10 can be corrected about the swing axis A1 and the swing axis A2. This can suppress image shake in two directions. As a result, the correction accuracy can be improved as compared with the case where the optical element 10 is swung around only one swing axis. In addition, the oscillation axis A1 is also referred to as a pitch axis. The pivot axis A2 is also referred to as a roll.

Therefore, the optical element 10 can be swung about the swing axis A1 intersecting the first direction X and the second direction Y. In addition, the optical element 10 can be swung about the swing axis A2 extending in the first direction X. This enables the posture of the optical element 10 to be appropriately corrected. The first direction X and the second direction Y are directions along the traveling direction of the light L. That is, the optical element 10 can be swung about the swing axis A1 intersecting the first direction X and the second direction Y, which are the traveling directions of light. Therefore, the posture of the optical element 10 can be corrected more appropriately.

In addition, the support body 30 supports the holder 20 in the third direction Z. Therefore, the support body 30 can be easily swung about the swing axis A1 extending in the third direction Z. Specifically, in the present embodiment, the support body 30 supports the holder 20 in the third direction Z via the pre-pressing portion 40.

The support body 30 has a support main 31 and a pair of side faces 32.

The support body 31 connects a pair of side faces 32. The support body 31 is opposed to the holder 20 in the first direction X.

The support body 31 has an accommodation hole 303a and a magnetic body 152. The accommodation hole 303a accommodates the magnetic body 152. The magnetic body 152 is disposed in the accommodation hole 303a. The magnetic body 152 is a plate-like member made of a magnetic body.

The pair of side portions 32 are disposed at both ends of the support body 31 in the third direction Z. The pair of side surfaces 32 have mutually symmetrical shapes in the third direction Z. The side surface portion 32 has an inner side surface 32a. The inner surface 32a faces the holder 20 in the third direction Z. The pair of side surfaces 32 are disposed on both sides of the holder 20 in the axial direction of the swing axis A1. The pair of side surfaces 32 have mutually symmetrical shapes in the third direction Z. The side surface portion 32 has a receiving recess 32f. The accommodation recess 32f faces outward in the third direction Z. The accommodation recess 32f accommodates at least a part of the magnet 51 of the swing mechanism 5.

The pre-pressing portion 40 connects the holder 20 and the support body 30. The pre-pressing portion 40 is elastically deformable. The pre-pressing portion 40 is disposed on at least one of the holder 20 and the support 30. The preload portion 40 applies preload to at least the other of the retainer 20 and the support 30 in the axial direction of the swing axis A1. Therefore, misalignment of the holder 20 with respect to the support body 30 in the axial direction of the swing axis A1 can be suppressed. In addition, even when manufacturing errors occur in the dimensions of the respective members, occurrence of rattling or the like in the axial direction of the rocking axis A1 can be suppressed. In other words, for example, the position of the holder 20 is prevented from being displaced in the axial direction of the swing axis A1. The axis direction of the swing axis A1 is a direction along the third direction Z. In the present specification, "imparting preload" means that a load is applied in advance.

The pre-pressing portion 40 is disposed between the holder 20 and the support 30. The preload portion 40 applies preload to the retainer 20 in the axial direction of the swing axis A1. In the present embodiment, each pre-pressing portion 40 is a single member. The pre-pressing portion 40 is formed by bending one plate member. In the present embodiment, the pre-pressing portion 40 is a plate spring. The pre-pressing portion 40 is disposed on the support 30.

The pre-pressing portion 40 has a first surface portion 41 located on the holder 20 side, a second surface portion 42 located on the support body 30 side, and a curved portion 43 connecting the first surface portion 41 and the second surface portion 42. Therefore, the pre-pressing portion 40 can be easily deformed in the axial direction of the swing axis A1. As a result, since the elastic force is generated by the deflection of the bending portion 43, the preload can be easily applied to the retainer 20 in the axial direction with a simple structure.

In the present embodiment, a pair of pre-pressing portions 40 are provided. That is, the optical unit 1 has a pair of pre-pressing portions 40. The pair of pre-pressing portions 40 are disposed on both sides of the holder 20 in the axial direction of the swing axis A1. Therefore, the retainer 20 can be supported more stably than in the case where the pre-pressing portion 40 is disposed only on one side of the retainer 20.

The pre-pressing portion 40 includes an on-axis convex portion 45, a protruding portion 46, and a mounting portion 47.

The shaft protruding portion 45 protrudes toward the holder 20. Specifically, the on-axis convex portion 45 is in contact with the on-axis concave portion 22b of the holder 20. More specifically, the shaft convex portions 45 of the pair of pre-pressing portions 40 are respectively in contact with the pair of shaft concave portions 22b of the holder 20. The retainer 20 is supported by the pre-pressing portions 40 from both sides in the axial direction of the swing axis A1 at two contact points with the shaft protruding portions 45. Therefore, the holder 20 can swing about the swing axis A1 passing through the two contact points.

The protruding portion 46 is disposed on one of the first surface portion 41 and the second surface portion 42, and protrudes toward one of the holder 20 and the support body 30. In the present embodiment, the protruding portion 46 is disposed on the first surface 41 in the same manner as the on-axis protruding portion 45. The protruding portion 46 protrudes toward the holder 20 in a direction along the swing axis A1. The protruding portion 46 is provided corresponding to the restricting recess 22c. Four projections 46 are provided for example in each pre-pressing portion 40. A part of the protruding portion 46 is accommodated in the restricting recess 22c. The protruding portion 46 is disposed so as to surround the on-axis protrusion 45. In other words, the on-axis convex portion 45 is disposed inside the region including the four protruding portions 46. The number of the protruding portions 46 may be, for example, one to three, or five or more. The protruding portion 46 is formed by bending an end portion of the first surface 41.

The mounting portion 47 is disposed on the second face 42, for example. The mounting portion 47 is disposed at the upper end of the second face portion 42. The mounting portion 47 is mounted on the upper end of the side surface portion 32 of the support body 30. The attachment portion 47 is attached to the side surface portion 32 by sandwiching the upper end of the side surface portion 32 in the first direction X, for example. The pre-pressing portion 40 may not have the mounting portion 47, and may be fixed to the support 30 using an adhesive or the like, for example.

Next, the housing unit 60 will be described in more detail with reference to fig. 2 to 5. As shown in fig. 5, the accommodating portion 60 further has a plurality of wall portions W. One of the wall portions W is provided with a support mechanism 7 described later. In addition, another wall W of the plurality of wall W supports at least a part of the base plate 80. The other wall portion W is connected to one wall portion W. Therefore, the housing portion 60 has a simple structure, and the substrate portion 80 can be fixed. As a result, the movable portion 2 can be swingably supported with a simple structure.

As shown in fig. 5, the plurality of wall portions W include a support body 61, a first side surface portion 62, a back surface portion 63, and a second side surface portion 64.

The support body 61 is disposed on one side X1 in the first direction X. The support body 61 corresponds to an example of "first wall portion". The support body 61 has a first accommodation recess 61b and at least two second accommodation recesses 61c. In the present embodiment, the support body 61 has one first accommodation recess 61b and two second accommodation recesses 61c. In the present embodiment, the case where the housing portion 60 has the first housing recess 61b and the second housing recess 61c has been described, but one of the movable portion 2 and the fixed portion 3 may have the first housing recess and the second housing recess recessed in the opposite direction to the other of the movable portion 2 and the fixed portion 3. For example, one of the movable portion 2 and the fixed portion 3 may have a first accommodation recess, and the other of the movable portion 2 and the fixed portion 3 may have a second accommodation recess.

The support main 61 is opposed to the lower surface of the support body 30 in the first direction X. The first accommodating recess 61b and the second accommodating recess 61c are recessed in the first direction X in a direction opposite to the movable portion 2. That is, the first accommodating recess 61b and the second accommodating recess 61c are recessed toward one side X1 in the first direction X. The first accommodating recess 61b is opposed to the first recess 31f of the support body 30 in the first direction X. The first accommodation recess 61b accommodates a part of the support mechanism 7. Further, a magnet 151p and a magnet 151q are disposed on the support body 61.

The back surface 63 is disposed at an end of the support body 61 on the other side Y2 in the second direction Y. The back surface 63 corresponds to an example of the "second wall".

The back surface 63 has a receiving hole 63a in which the magnetic body 84 is disposed. The accommodation hole 63a corresponds to an example of a "concave portion". The accommodation hole 63a penetrates the back surface portion 63 in the thickness direction. That is, the accommodation hole 63a penetrates the back surface portion 63 in the second direction Y.

The first side surface portion 62 is disposed on one side Z1 of the support body 61 in the third direction Z. The first side surface portion 62 corresponds to an example of "third wall portion". The first side surface portion 62 has a shape symmetrical to the second side surface portion 64. The first side surface portion 62 is connected to the support body 61 and the back surface portion 63 at one side Z1 in the third direction Z.

The first side surface 62 has a receiving hole 62a in which the magnetic body 84 is disposed. The accommodation hole 62a corresponds to an example of a "concave portion". The accommodation hole 62a penetrates the first side surface portion 62 in the thickness direction. That is, the accommodation hole 62a penetrates the first side surface portion 62 in the third direction Z.

The second side surface portion 64 is disposed on the other side Z2 of the third direction Z of the support body 61. The second side surface portion 64 corresponds to an example of "a fourth wall portion". The second side surface portion 64 is opposed to the first side surface portion 62. Therefore, the movable portion 2 can be swingably supported, while the substrate portion 80 is supported by the support body 61, the back surface portion 63, the first side surface portion 62, and the second side surface portion 64. As a result, positional displacement of the substrate 80 can be suppressed.

The second side surface portion 64 has a receiving hole 64a and a through hole 67. The accommodation hole 64a in which the magnetic body 84 is disposed corresponds to an example of a "concave portion". The accommodation hole 64a penetrates the second side surface portion 64 in the thickness direction. That is, the accommodation hole 64a penetrates the second side surface portion 64 in the third direction Z.

The through hole 67 penetrates the inside and outside of the housing 60. Specifically, the second side surface portion 64 penetrates in the thickness direction. That is, the through hole 67 penetrates the second side surface portion 64 in the third direction Z.

Next, the substrate portion 80 will be described in more detail with reference to fig. 2 to 5. As shown in fig. 5, the substrate portion 80 includes a connection terminal 82, a substrate main body 81, and a connection portion 85.

The connection terminal 82 is disposed on the substrate body 81. The connection terminal 82 is electrically connected to a terminal of a hall element, not shown. In addition, for example, four connection terminals 82 are provided for one hall element.

The substrate main body 81 has a first substrate 81a, a second substrate 81b, and a third substrate 81c. The first substrate 81a is located between the second substrate 81b and the third substrate 81c. The first substrate 81a is located on the other side Y2 in the second direction Y. The first substrate 81a extends in the third direction Z. The first substrate 81a supplies electric power to a first coil 52a described later.

The second substrate 81b is located on one side Z1 in the third direction Z with respect to the first substrate 81a than the third substrate 81c. The second substrate 81b extends from the first substrate 81a along one side Y1 in the second direction Y. That is, the second substrate 81b is bent toward one side Y1 in the second direction Y with respect to the first substrate 81a extending along the third direction Z. The second substrate 81b supplies electric power to a second coil 52b described later.

The third substrate 81c is positioned on the other side Z2 in the third direction Z than the second substrate 81b with respect to the first substrate 81 a. The third substrate 81c extends from the first substrate 81a along one side Y1 in the second direction Y. That is, the third substrate 81c is bent toward one side Y1 in the second direction Y with respect to the first substrate 81a extending along the third direction Z. The third substrate 81c is opposed to the second substrate 81 b. The third substrate 81c supplies electric power to a third coil 52c described later.

In the present embodiment, the first substrate 81a is supported by the back surface 63. The second substrate 81b is supported on the first side surface portion 62. The third substrate 81c is supported by the second side surface portion 64. Therefore, the second substrate 81b can be prevented from expanding toward the first side surface portion 62, and the third substrate 81c can be prevented from expanding toward the second side surface portion 64. As a result, the positions of the second coil 52b and the third coil 52c can be suppressed from being changed from the positions desired by the designer.

In the present embodiment, the first substrate 81a is supported by the back surface 63, the second substrate 81b is supported by the first side surface 62, and the third substrate 81c is supported by the second side surface 64. Accordingly, the first substrate 81a, the second substrate 81b, and the third substrate 81c can be prevented from being deflected. In the conventional optical unit, a metal or resin thin plate called a reinforcing plate is generally attached to suppress bending of the FPC. Here, unlike the conventional optical unit, the optical unit 1 of the present embodiment can omit the attachment of a reinforcing plate to the FPC. That is, the reinforcing plates may not be disposed on the first substrate 81a, the second substrate 81b, and the third substrate 81c, respectively. Therefore, in manufacturing the substrate portion 80, the step of disposing the reinforcing plates on the first substrate 81a, the second substrate 81b, and the third substrate 81c can be omitted.

In addition, as shown in fig. 5, the substrate body 81 includes a first cutout region 88 and a second cutout region 89. The first cutout region 88 is located between the first coil 52a and the second coil 52 b. The second cutout region 89 is located between the first coil 52a and the third coil 52 c. The first cutout region 88 and the second cutout region 89 are located on one side X1 of the substrate main body 81 in the first direction X. Therefore, the shape of one side X1 of the substrate main body 81 in the first direction X can be made different from the shape of the other side X2 of the substrate main body 81 in the first direction X. As a result, the substrate portion 80 can be arranged in the first positioning portion 65 of the housing portion 60 with the first cutout region 88 and the second cutout region 89 as marks.

The connection portion 85 is connected to a wiring, not shown. The connection portion 85 is supplied with electric power via wiring. The connection portion 85 supplies power to the first substrate 81a, the second substrate 81b, and the third substrate 81c. The connection portion 85 is located on the third substrate 81c. Specifically, the connection portion 85 is located on one side X1 of the third substrate 81c in the first direction X.

The connection portion 85 is disposed in the through hole 67. The connection portion 85 corresponds to an example of "disposed at least in a portion of the through hole 67". When the substrate 80 is positioned at the first positioning portion 65, the connection portion 85 is disposed at the through hole 67. Thus, the connection portion 85 is located outside the receiving portion 60. As a result, the connection portion 85 is easily connected to the wiring. That is, the processing of wiring to the optical unit 1 becomes easy.

Next, the supporting mechanism 7 of the optical unit 1 will be described with reference to fig. 5. The support mechanism 7 has a first convex portion 71 and a plurality of second convex portions 72. The first protruding portion 71 protrudes toward the movable portion 2 and the fixed portion 3. Specifically, the first protruding portion 71 protrudes toward the support body 30 and the accommodating portion 60. That is, the movable portion 2 and the fixed portion 3 are in contact with the first convex portion 71. A part of the first protruding portion 71 is accommodated in the first accommodating recess portion 61b. The first protruding portion 71 is disposed on the swing axis A2. Therefore, the movable portion 2 swings about the first convex portion 71. Therefore, the length from the contact position of the movable portion 2 and the fixed portion 3 to the swing center can be reduced. Since the force required for swinging the movable portion 2 is a product of the friction force and the length from the contact position to the swing center, the force required for swinging the movable portion 2 can be reduced by disposing the first protruding portion 71 on the swing axis A2. That is, the force required for driving the optical unit 1 can be reduced. The material of the first protruding portion 71 is not particularly limited, but the first protruding portion 71 is formed of, for example, ceramic, resin, or metal.

Further, by disposing the first protruding portion 71 on the swing axis A2, the contact position between the movable portion 2 and the fixed portion 3 does not move relative to the first protruding portion 71. Therefore, for example, compared with a case where the other of the movable portion 2 and the fixed portion 3 slides with respect to the first convex portion 71 when the movable portion 2 swings, the friction force between the other of the movable portion 2 and the fixed portion 3 and the first convex portion 71 can be reduced. Further, since the optical axis L10 and the swing axis A2 are arranged to overlap, it is possible to suppress the optical axis L10 from being deviated from the swing axis A2 when the movable portion 2 is swung.

In the present embodiment, the first protruding portion 71 is disposed in the fixing portion 3. Therefore, the first protruding portion 71 can be restrained from rotating when the movable portion 2 swings. Therefore, the movable portion 2 can be stably supported by the first protruding portion 71. As a result, the swing of the movable portion 2 is stabilized.

The plurality of second protrusions 72 protrude toward the movable portion 2 and the fixed portion 3. Specifically, the plurality of second protrusions 72 protrude toward the support body 30 and the accommodating portion 60. A part of the second convex portion 72 is accommodated in the second accommodating concave portion 61c. The plurality of second protrusions 72 are disposed at positions apart from the swing axis A2. The plurality of second protrusions 72 contact the movable portion 2 and the fixed portion 3.

The first projection 71 and the plurality of second projections 72 are disposed on the same plane intersecting the swing axis A2. Therefore, the movable portion 2 can be supported by the first protruding portion 71 and the plurality of second protruding portions 72 arranged on the same plane. As a result, the movable portion 2 can be stably supported. The material of the second convex portion 72 is not particularly limited, and the second convex portion 72 is formed of, for example, ceramic, resin, or metal.

In addition, the position of the second convex portion 72 is constant. In other words, the second protruding portion 72 does not move with respect to one of the movable portion 2 and the fixed portion 3. In the present embodiment, the second protruding portion 72 does not move with respect to the fixed portion 3. In other words, in the present embodiment, even when the movable portion 2 swings, the position of the second protruding portion 72 with respect to the fixed portion 3 is constant. Therefore, the movable portion 2 can be supported more stably.

In the present embodiment, the number of the second protrusions 72 is two. Accordingly, since the movable portion 2 is supported by three projections (the first projection 71 and the second projection 72), the movable portion 2 can be supported more stably than in the case where the movable portion 2 is supported by four or more projections. In addition, in the present embodiment, since the movable portion 2 is in point contact with three points, the movable portion 2 can be supported more stably.

Next, the first positioning portion 65 will be described in more detail with reference to fig. 5. As shown in fig. 5, the first positioning portion 65 has a back positioning portion 65a, a first side positioning portion 65b, and a second side positioning portion 65c.

The back positioning portion 65a is located on the back portion 63. The back positioning portion 65a is recessed in the thickness direction of the back surface portion 63. The back positioning portion 65a determines the position of the first substrate 81a. Specifically, the back positioning portion 65a is a hole that recesses the back surface portion 63 toward the other side Y2 in the second direction Y.

That is, the first substrate 81a is accommodated in the back surface positioning portion 65a. In other words, the back positioning portion 65a supports the first substrate 81a. The back positioning portion 65a can prevent the first substrate 81a from moving to one side X1 of the first direction X and the other side X2 of the first direction X beyond the back positioning portion 65a. The back surface positioning portion 65a suppresses the first substrate 81a from moving to the other side Y2 in the second direction Y.

The first side positioning portion 65b is located on the first side portion 62. The first side positioning portion 65b is recessed in the thickness direction of the first side portion 62. The first side positioning portion 65b determines the position of the second substrate 81b. That is, the first side positioning portion 65b is a hole that recesses the first side surface portion 62 toward one side Z1 in the third direction Z.

That is, the second substrate 81b is accommodated in the first side positioning portion 65b. In other words, the first side positioning portion 65b supports the second substrate 81b. The first side positioning portion 65b can prevent the second substrate 81b from moving beyond the first side positioning portion 65b to one side X1 of the first direction X and the other side X2 of the first direction X. The first side positioning portion 65b can prevent the second substrate 81b from moving beyond the first side positioning portion 65b to one side Y1 in the second direction Y. In addition, the first side positioning portion 65b suppresses the movement of the second substrate 81b to one side Z1 in the third direction Z.

The first side positioning portion 65b and the back positioning portion 65a can restrain the first substrate 81a from moving beyond the first side positioning portion 65b to one side Z1 in the third direction Z. The back surface positioning portion 65a and the first side surface positioning portion 65b can restrain the second substrate 81b from moving to the other side Y2 in the second direction Y beyond the back surface positioning portion 65 a.

The second side positioning portion 65c is located at the second side portion 64. The second side positioning portion 65c determines the position of the third substrate 81c. The second side positioning portion 65c is recessed in the thickness direction of the second side portion 64. The second side positioning portion 65c determines the position of the third substrate 81c. That is, the second side positioning portion 65c is a hole that recesses the second side surface portion 64 toward the other side Z2 in the third direction Z.

That is, the third substrate 81c is accommodated in the second side positioning portion 65 c. In other words, the second side positioning portion 65c supports the third substrate 81c. Therefore, the second side surface positioning portion 65c suppresses the movement of the third substrate 81c to the other side Z2 in the third direction Z.

The second side surface positioning portion 65c can prevent the third substrate 81c from moving beyond the second side surface positioning portion 65c to one side X1 of the first direction X and the other side X2 of the first direction X. The second side surface positioning portion 65c can prevent the third substrate 81c from moving beyond the second side surface positioning portion 65c to one side Y1 in the second direction Y.

The second side surface positioning portion 65c and the back surface positioning portion 65a can prevent the first substrate 81a from moving beyond the second side surface positioning portion 65c to the other side Z2 in the third direction Z. The second side surface positioning portion 65c and the back surface positioning portion 65a can prevent the third substrate 81c from moving to the other side Y2 in the second direction Y beyond the back surface positioning portion 65 a.

Next, the swing mechanism 5 of the optical unit 1 will be described in detail with reference to fig. 2 to 5.

As shown in fig. 2, the swinging mechanism 5 swings the holder 20 with respect to the support 30 about the swinging axis A1. The swinging mechanism 5 swings the support body 30 about the swinging axis A2 with respect to the accommodating portion 60. Therefore, the optical element 10 can be easily swung with the two swing axes (the swing axis A1 and the swing axis A2) as the center, respectively.

As shown in fig. 2, the magnet 51 of the swinging mechanism 5 includes a first magnet 51a, a second magnet 51b, and a third magnet 51c.

Specifically, the second magnet 51b is disposed in the accommodation recess 32f of the side surface portion 32 of the support body 30. That is, the second magnet 51b is disposed on one side Z1 in the third direction Z. The second magnet 51b has an n-pole portion made up of an n-pole and an s-pole portion made up of an s-pole. The second magnet 51b is polarized in a second direction Y intersecting the first direction X. Therefore, the movable portion 2 can be swung about the swing axis A2 along the light incident direction.

The third magnet 51c is disposed in the movable portion 2 or the fixed portion 3. In the present embodiment, the third magnet 51c is disposed on one of the support 30 and the housing 60. Specifically, the third magnet 51c is disposed in the accommodation recess 32f of the side surface portion 32 of the support body 30. In the present embodiment, the third magnet 51c is disposed on the other side Z2 in the third direction Z. The third magnet 51c has an n-pole portion made up of an n-pole and an s-pole portion made up of an s-pole. The third magnet 51c is polarized in a second direction Y intersecting the first direction X. Therefore, the movable portion 2 can be swung about the swing axis A2 along the light incident direction.

As shown in fig. 3, the coil 52 of the swing mechanism 5 includes a first coil 52a, a second coil 52b, and a third coil 52c.

The first coil 52a faces the first magnet 51a in the second direction Y. In the present embodiment, the first coil 52a is disposed on the first substrate 81a. The first substrate 81a provided with the first coil 52a is disposed on the back surface positioning portion 65a. Therefore, the first coil 52a can be restrained from swinging relative to the housing portion 60.

By energizing the first coil 52a, a magnetic field is generated around the first coil 52 a. Then, a force due to the magnetic field acts on the first magnet 51 a. As a result, the holder 20 and the optical element 10 swing with respect to the support body 30 and the accommodating portion 60 about the swing axis A1.

The second coil 52b faces the second magnet 51 b. Specifically, the second coil 52b faces the second magnet 51b on one side Z1 in the third direction Z. In the present embodiment, the second coil 52b is disposed on the second substrate 81b. The second substrate 81b on which the second coil 52b is disposed on the first side positioning portion 65b. Therefore, the second coil 52b can be restrained from swinging relative to the housing portion 60.

The third coil 52c faces the third magnet 51 c. Specifically, the third coil 52c faces the third magnet 51c on the other side Z2 in the third direction Z. In the present embodiment, the third coil 52c is disposed on the third substrate 81c. The third substrate 81c on which the third coil 52c is disposed on the second side surface positioning portion 65c.

The second coil 52b and the third coil 52c are energized, and a magnetic field is generated around the second coil 52b and around the third coil 52 c. Then, a force due to the magnetic field acts on the second magnet 51b and the third magnet 51 c. As a result, the support 30, the holder 20, and the optical element 10 swing with respect to the accommodating portion 60 about the swing axis A2.

As shown in fig. 5, the magnetic body 84 of the swing mechanism 5 includes a first magnetic body 84a, a second magnetic body 84b, and a third magnetic body 84c.

The first magnetic body 84a faces the first magnet 51 a. The first magnetic body 84a is disposed in the accommodation hole 63a of the back surface 63. In a state where the first coil 52a is not energized, attractive force is generated between the first magnet 51a and the first magnetic body 84 a. Therefore, the movable portion 2 is disposed at the reference position in the rotation direction around the swing axis A1. Further, by generating attractive force between the first magnet 51a and the first magnetic body 84a, the retainer 20 can be prevented from coming out to the one side Y1 in the second direction Y.

The second magnetic body 84b faces the second magnet 51 b. The second magnetic body 84b is disposed in the accommodation hole 62a of the first side surface portion 62. In a state where the second coil 52b is not energized, attractive force is generated between the second magnet 51b and the second magnetic body 84 b.

Therefore, the movable portion 2 is disposed at the reference position in the rotation direction around the swing axis A2.

Next, the housing unit 60 according to the present embodiment will be described in more detail with reference to fig. 6. Fig. 6 is a diagram showing the housing 60 of the optical unit 1 according to the present embodiment. The housing portion 60 of the present embodiment has a second positioning portion 68 and a third positioning portion 69.

That is, the third positioning portion 69 extends toward one side Z1 of the third direction Z. The third positioning portion 69 determines the positions of the first substrate 81a and the third substrate 81 c. Thus, the first substrate 81a is positioned by the second positioning portion 68 and the third positioning portion 69. Further, the second substrate 81b is positioned by the second positioning portion 68. Further, the third substrate 81c is positioned by the third positioning portion 69.
