Description

Technical Field

[0001] The present invention relates to an optical unit with jitter correction function that performs jitter correction by oscillating an optical module. Background Technology

[0002] In an optical unit installed in a portable terminal or mobile device, a mechanism is provided to correct shake by swinging or rotating a movable body equipped with the optical module in order to suppress image distortion when the portable terminal or mobile device moves. Such an optical unit with shake correction function is disclosed in Patent Document 1.

[0003] The optical unit with jitter correction function in Patent Document 1 includes: a movable body having an optical module; a fixed body; and a swing support mechanism that supports the movable body so that it can rotate relative to the fixed body about rotation axes (X-axis, Y-axis) intersecting the optical axis. A flexible printed circuit board (flexible wiring board) connected to the optical module is led out from the movable body. The end (fixed end) of the flexible printed circuit board is fixed to a positioning part provided on the fixed body.

[0004] In an optical unit with jitter correction, a movable body oscillates while bending a flexible printed circuit board. At this time, due to the elasticity of the flexible printed circuit board, the movement of the movable body is hindered, sometimes increasing the load required to make the movable body oscillate. In Patent Document 1, to make the flexible printed circuit board easier to bend, the flexible printed circuit board is folded into an overlapping shape when viewed from the optical axis.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2020-86367 Summary of the Invention

[0008] In Patent Document 1, a space for accommodating a flexible printed circuit board is provided adjacent to a movable body. The flexible printed circuit board extends away from the movable body and then folds back in the opposite direction. When the flexible printed circuit board is folded back in this direction, the distance from the movable body to the folding position of the flexible printed circuit board is relatively large. Therefore, it is difficult to miniaturize the space for accommodating the flexible printed circuit board as viewed from the optical axis, and it is difficult to miniaturize the optical unit with jitter correction function.

[0009] The objective of this invention is to reduce the oscillation load of a movable body caused by deformation of a flexible printed circuit board, and to miniaturize an optical unit with jitter correction function, in view of such problems.

[0010] To address the aforementioned issues, the optical unit with jitter correction function of the present invention is characterized by comprising: a movable body having an optical module; a fixed body; a swing support mechanism that supports the movable body so that it can swing relative to the fixed body about a first swing axis intersecting the optical axis, and supports the movable body so that it can swing about a second swing axis intersecting the optical axis and the first swing axis; a jitter correction drive mechanism that causes the movable body to swing about the first swing axis and to swing about the second swing axis; and a flexible printed circuit board extending from the movable body, wherein, when the direction along the first swing axis is designated as a first direction and the direction along the second swing axis is designated as a second direction, the flexible printed circuit board comprises: a first portion disposed at a position away from the movable body towards the first direction; and a second portion connecting the movable body and the first portion, the first portion having a fixing portion directly or indirectly fixed to the fixed body, and the second portion having a flexural portion that extends along the optical axis while meandering along the second direction.

[0011] According to the present invention, a flexible printed circuit board connected to a movable body has a flexural portion on the side of the movable body (one side in the first direction). This flexural portion meanders along the side of the movable body in the direction of the second direction and extends along the optical axis. Therefore, since multiple straight portions of the flexural portion extending in the second direction are overlapped in the optical axis direction, these straight portions tend to tilt when the movable body rotates about the first swing axis. Furthermore, when the movable body rotates about the second swing axis, the flexural portion as a whole tends to expand and contract along the optical axis. Therefore, when the movable body rotates in either direction about the first or the second swing axis, the spring constant of the flexible printed circuit board during deformation is small, resulting in a small swing load on the movable body. Additionally, since the flexural portion can be arranged along the side of the movable body in the first direction, the arrangement space only needs to accommodate the width of the flexible printed circuit board extending in the second direction, thus the width of the arrangement space in the first direction is small. Therefore, the length of the optical unit with jitter correction function in the first direction can be reduced, enabling miniaturization of the optical unit with jitter correction function.

[0012] In this invention, the second portion preferably includes an extension portion connecting the movable body and the flexible portion. The extension portion includes a standing portion extending along the optical axis, and the flexible portion is connected to the extension portion on an imaginary surface containing the swing center of the movable body and perpendicular to the optical axis. Thus, by providing the standing portion between the movable body and the flexible portion, a flexible printed circuit board extended from any position of the movable body can be wound to a position at the same height as the swing center of the movable body. Consequently, the movable body side end of the flexible portion (i.e., the connection portion between the flexible portion and the extension portion) is positioned in the optical axis direction at the same position as the swing center of the movable body. Therefore, in either case when the movable body rotates about the first swing axis or about the second swing axis, the displacement of the connection portion between the flexible portion and the extension portion in the optical axis direction is small. Furthermore, by reducing the displacement of this portion, the maximum displacement of the flexible portion can be reduced. Therefore, miniaturization of the optical unit with jitter correction function is possible. Alternatively, when the movable body swings, it can prevent the part with the largest displacement in the flexural portion from colliding with the fixed body. Therefore, it can avoid damage to the flexible printed circuit board and suppress the increase in swing load caused by the hindrance of deformation of the flexible printed circuit board.

[0013] In this invention, it is preferable that the center of the upright portion in the second direction is at the same position as the swing center in the second direction. This ensures that, when viewed from the first direction, the connection between the flexure portion and the lead-out portion is located at a position overlapping with the swing center of the movable body. Consequently, when the movable body rotates around the first swing axis, the connection between the flexure portion and the lead-out portion will not displace in the optical axis direction, thus reducing the maximum displacement of the flexure portion. Furthermore, since the connection between the flexure portion and the lead-out portion separates from both ends of the flexure portion, the maximum displacement of the flexure portion can be reduced when the movable body rotates around the second swing axis. Therefore, miniaturization of the optical unit with jitter correction function is possible. Alternatively, damage to the flexible printed circuit board can be avoided, and the increase in swing load caused by the obstruction of deformation of the flexible printed circuit board can be suppressed.

[0014] In this invention, it is preferable that the flexural portion extends along the second direction and folds back at least twice in the opposite direction. This allows the flexural portion to flex easily in either case when the movable body rotates about the first oscillation axis or about the second oscillation axis. Therefore, the spring constant during deformation of the flexible printed circuit board is small.

[0015] In this invention, it is preferable that the total number of the folded portions of the flexural portion folding back from one side of the second direction to the other and the folded portions folding back from the other side of the second direction to one side is even. This ensures that when the movable body rotates, the portion on one side of the flexural portion in the second direction and the portion on the other side of the second direction deform in a balanced and good manner, thus preventing the swing load of the movable body from changing due to the direction of rotation. Therefore, it is easier to control the tilt of the movable body.

[0016] In this invention, it is preferable that both the folded-back portion folding back from one side to the other in the second direction and the folded-back portion folding back from the other side to one side in the second direction are folded back at acute angles. This allows for the formation of a flexible printed circuit board that can be bent into a Z-shape. Since the folded-back portion is easy to open and close in the optical axis direction, the spring constant of the Z-shaped flexible portion is small. Therefore, the oscillation load on the movable body can be reduced.

[0017] In this invention, preferably, both the folding portion of the flexural portion that folds back from one side of the second direction to the other and the folding portion that folds back from the other side of the second direction to one side are folded back in a curved shape, and a shape-holding member is fixed to maintain the curved folding shape. This avoids the flexural portion losing its shape due to springback, making it easier to maintain the shape of the flexural portion. Therefore, the movable body has good assemblability.

[0018] In this invention, the flexural portion preferably comprises a first substrate and a second substrate stacked in a mutually separated state. Furthermore, in this case, it is preferable that the first substrate and the second substrate are double-sided substrates. This allows for an increase in wiring area without increasing the spring constant.

[0019] In this invention, the lead-out portion preferably comprises: a first planar portion extending from the optical module toward one side in the first direction; a standing portion extending from the first planar portion toward one side in the optical axis direction; and a second planar portion extending from the end of the standing portion on one side in the optical axis direction toward one side in the first direction and connected to the flexible portion. The movable body has a retainer surrounding the optical module, the lead-out portion passing through a notch provided on the retainer, the standing portion being disposed inside the notch, and a pair of grooves opposite each other in the second direction being provided on the inner side of the notch. A reinforcing plate is fixed to the standing portion, the reinforcing plate protruding from both sides of the standing portion in the second direction and embedded in the grooves. This eliminates the need to ensure space for the standing portion outside the movable body. Therefore, the space required for the flexible printed circuit board can be reduced, and the optical unit with jitter correction function can be miniaturized. Furthermore, since the lead-out portion can be easily held on the retainer, the assemblability during assembly of the movable body is good. Furthermore, since the lead-out portion can be positioned relative to the cage, the flexural portion can be positioned appropriately via the lead-out portion.

[0020] In this invention, the inner surface of the notch preferably includes: a first guide surface extending along the optical axis direction on the opposite side of the pair of grooves in the first direction; and a second guide surface extending from one end of the first guide surface in the optical axis direction toward the first direction. The raised portion is disposed between the first guide surface and the reinforcing plate, and the second planar portion contacts the second guide surface. In this way, since the second planar portion can be positioned in the optical axis direction, the flexural portion can be positioned appropriately in the optical axis direction via the second planar portion.

[0021] Invention Effects

[0022] According to the present invention, a flexible printed circuit board connected to a movable body has a flexural portion on the side of the movable body (one side in the first direction). This flexural portion meanders along the side of the movable body in the direction of the second direction and extends along the optical axis. Therefore, since multiple straight portions of the flexural portion extending in the second direction are overlapped in the optical axis direction, these straight portions tend to tilt when the movable body rotates about the first swing axis. Furthermore, when the movable body rotates about the second swing axis, the flexural portion as a whole tends to expand and contract along the optical axis. Therefore, when the movable body rotates in either direction about the first or the second swing axis, the spring constant of the flexible printed circuit board during deformation is small, resulting in a small swing load on the movable body. Additionally, since the flexural portion can be arranged along the side of the movable body in the first direction, the arrangement space only needs to accommodate the width of the flexible printed circuit board extending in the second direction, thus the width of the arrangement space in the first direction is small. Therefore, the length of the optical unit with jitter correction function in the first direction can be reduced, enabling miniaturization of the optical unit with jitter correction function.

[0032] Hereinafter, embodiments of the optical unit with jitter correction function of the present invention will be described with reference to the accompanying drawings.

[0033] (Overall structure)

[0034] Figure 1 This is a perspective view of the optical unit 1 with jitter correction function applied according to the present invention. Figure 2 yes Figure 1 An exploded perspective view of the optical unit 1 with jitter correction function. Figure 3 This is a cross-sectional view of the optical unit 1 with jitter correction function, cut along the XZ plane. Figure 4 This is a top view of the optical unit with shake correction function after removing cover 22.

[0035] The optical unit 1 with image correction function includes a camera module 4 as an optical module, which has a lens 2 and an image sensor (not shown). The optical unit 1 with image correction function is used, for example, in optical devices such as mobile phones with cameras, dashcams, action cameras mounted on mobile bodies such as helmets, bicycles, and radio-controlled helicopters, and wearable cameras. In such optical devices, if the optical device shakes during photography, the captured image will be distorted. To avoid tilting the captured image, the optical unit 1 with image correction function corrects the tilt of the camera module 4 based on acceleration, angular velocity, and the amount of jitter detected by a detection unit such as a gyroscope.

[0036] The optical unit 1 with shake correction function causes the camera module 4 to rotate around a first axis R1 (refer to) that is orthogonal to the optical axis L of the lens 2 of the camera module 4. Figure 2 , Figure 4 Rotate the camera module 4 around a second axis R2 that is orthogonal to the optical axis L and the first axis R1 (refer to...). Figure 2 , Figure 4 The optical unit 1 with jitter correction function in this embodiment performs pitch correction and yaw correction.

[0037] In the following description, the three mutually orthogonal axes are designated as the X-axis, Y-axis, and Z-axis. The Z-axis coincides with the optical axis L. When the plane containing the X-axis and Y-axis is designated as the XY plane, the first axis R1 and the second axis R2 lie on the XY plane. The first axis R1 and the second axis R2 are tilted at 45 degrees relative to the X-axis and Y-axis, respectively.

[0038] In the following explanation, the directions along the X-axis, Y-axis, and Z-axis will be designated as the X-axis direction, Y-axis direction, and Z-axis direction, respectively. The X-axis direction is the first direction, and the Y-axis direction is the second direction. One side of the X-axis direction (first direction) is designated as the -X direction, and the other side as the +X direction. One side of the Y-axis direction (second direction) is designated as the -Y direction, and the other side as the +Y direction. One side of the Z-axis direction is designated as the -Z direction, and the other side as the +Z direction. The Z-axis direction is along the optical axis L. One side of the optical axis direction is consistent with the +Z direction, and the other side is consistent with the -Z direction. The -Z direction is the image side of camera module 4, and the +Z direction is the subject side of camera module 4.

[0039] The optical unit 1 with shake correction function includes: a movable body 5, which has a camera module 4; a gimbal mechanism 7; a fixed body 8, which supports the movable body 5 via the gimbal mechanism 7; and a shake correction drive mechanism 6 (see reference). Figure 4 ); and flexible printed circuit boards 9 and 10. Flexible printed circuit board 9 is connected to movable body 5. Flexible printed circuit board 10, which supplies power to jitter correction drive mechanism 6, is fixed to fixed body 8.

[0040] The gimbal mechanism 7 is a swing support mechanism that supports the movable body 5 so that it can swing about a first axis R1 and a second axis R2. The movable body 5 can rotate in the pitch direction about the X-axis and the deflection direction about the Y-axis by combining rotations about the first axis R1 and rotations about the second axis R2. That is, the gimbal mechanism 7 supports the movable body 5 so that it can swing about the X-axis and the Y-axis. The X-axis is the first swing axis, and the Y-axis is the second swing axis.

[0041] The jitter correction drive mechanism 6 includes: a first jitter correction drive mechanism 6X, which generates a driving force on the movable body 5 about the X-axis (about the first swing axis); and a second jitter correction drive mechanism 6Y, which generates a driving force on the movable body 5 about the Y-axis (about the second swing axis). Figure 3 As shown, in this embodiment, the first jitter correction drive mechanism 6X is disposed in the -Y direction of the movable body 5. The second jitter correction drive mechanism 6Y is disposed in the -X direction of the movable body 5.

[0042] (Moveable body)

[0043] like Figure 3 As shown, the movable body 5 includes a camera module 4 and a resin retainer 15 surrounding the camera module 4. The camera module 4 includes a lens barrel 4a that holds the lens 2 and a cuboid camera module body 4b disposed inside the retainer 15. The lens barrel 4a protrudes from the center of the camera module body 4b in the +Z direction. The camera module 4 includes a substrate 3 disposed at the -Z end of the camera module body 4b. An imaging element (not shown) is disposed on the substrate 3.

[0044] The flexible printed circuit board 9 is connected to the substrate 3 and extends from the end of the camera module 4 in the -Z direction toward the +X direction. The retainer 15 is a frame-shaped component surrounding the outer periphery of the camera module body 4b, and has a first frame portion 14 extending in the Y-axis direction along the side 4c of the camera module body 4b in the +X direction. Figure 2 , Figure 3 As shown, the flexible printed circuit board 9 extends into the movable body 5 in the +X direction through the notch 13 provided in the first frame portion 14. Figure 2 As shown, a protrusion 18 protruding in the +X direction is provided at the center of the first frame portion 14 in the Y-axis direction. A notch portion 13 is provided on the protrusion 18.

[0045] like Figure 4 As shown, a first magnet 61X is fixed to the side of the movable body 5 in the -Y direction. A second magnet 61Y is also fixed to the side of the movable body 5 in the -X direction. The first magnet 61X and the second magnet 61Y are disposed in recesses provided on the outer peripheral surface of the retainer 15. The first magnet 61X and the second magnet 61Y are polarized and magnetized along the Z-axis direction. At diagonal portions along the first axis R1 of the retainer 15, first recesses 17 are respectively provided for arranging universal joint frame receiving members 16.

[0046] (Fixed body)

[0047] like Figure 2 As shown, the fixed body 8 includes: a shell 19 surrounding the outer periphery of the movable body 5; a base 20 fixed to the shell 19 in the -Z direction; and a cover 21 covering the shell 19 in the +Z direction. The shell 19 is made of metal, and the base 20 and cover 21 are also made of metal. The shell 19 is housed between the base 20 and the cover 21. Figure 1 , Figure 3 As shown, a portion of the movable body 5 and the universal joint mechanism 7 protrudes from the opening 21a of the cover 21 in the +Z direction.

[0048] like Figure 2 , Figure 3 , Figure 4 As shown, a wiring storage section 22 is provided at the +X end of the housing 19, which covers the flexible printed circuit board 9 extending from the movable body 5 in the +X direction from the +Z direction. Furthermore, a movable body storage section 23 extending through the housing 19 along the Z-axis direction is provided in the -X direction of the wiring storage section 22. Figure 2 , Figure 4As shown, in the diagonal portion of the movable body storage section 23 along the second axis R2, there are second recesses 24 for mounting the universal joint frame receiving member 16. The universal joint receiving member 16 fixed to the housing 19 is the same as the universal joint frame receiving member 16 fixed to the retainer 15 of the movable body 5, and has a convex curved surface protruding radially inward (not shown).

[0049] like Figure 3 As shown, the +X end of the base 20 covers the wiring storage section 22 from the -Z direction. The flexible printed circuit board 9 is housed between the base 20 and the wiring storage section 22, and extends from the wiring storage section 22 in the +X direction.

[0050] Figure 5 (a) is a bottom view of the optical unit 1 with jitter correction function after the base 20 has been removed. Additionally, Figure 5 (b) is a cross-sectional view showing the holding structure of the flexible printed circuit board 9 based on the retainer 15, which is... Figure 5 Region A of (a) is in Figure 3 The diagram shows a partial cross-sectional view cut off at the BB location. (See attached image.) Figure 5 As shown in (a), a pair of wall portions 25 and 26 extending along the X-axis are arranged at both ends of the wiring storage section 22 in the Y-axis direction. Additionally, a pair of wall portions 27 and 28 extending along the Y-axis are arranged at both ends of the wiring storage section 22 in the X-axis direction. Furthermore, the wiring storage section 22 includes an end plate portion 29 that blocks the space surrounded by the wall portions 25, 26, 27, and 28 in the +Z direction (see reference). Figure 3 ).

[0051] The wall 27 of the wiring storage section 22 surrounds the movable body storage section 23 in the +X direction. The flexible printed circuit board 9 passes through the notch 30 formed by cutting away the central portion in the Y-axis direction of the wall 27 and is led out between a pair of walls 25 and 26. Figure 2 , Figure 3 As shown, the notch 30 extends to the edge of the end plate portion 29 in the -X direction. The flexible printed circuit board 9 meanders in a serpentine shape between a pair of wall portions 25 and 26, extending from the gap between the notch 31, which is located at the edge of the wall portion 28 in the -Z direction, and the base 20 in the +X direction.

[0052] like Figure 2 As shown, a coil mounting hole 33 for mounting the first coil 62X is provided on the side of the housing 19 in the -Y direction. Additionally, a coil mounting hole 33 for mounting the second coil 62Y is provided on the side of the housing 19 in the -X direction. Figure 2As shown, the first coil 62X and the second coil 62Y are elongated oval hollow coils with a longer circumferential direction. The first coil 62X and the second coil 62Y are electrically connected to the flexible printed circuit board 10. The flexible printed circuit board 10 is wound along the -X and -Y side surfaces of the housing 19, extends from the -Y side surface of the housing 19 to the -Y side surface of the wiring storage portion 22, and is connected to a power supply board (not shown).

[0053] (Unidirectional frame mechanism)

[0054] like Figure 4 As shown, the gimbal mechanism 7 includes a gimbal frame 70, a first connecting mechanism 71, and a second connecting mechanism 72. The first connecting mechanism 71 connects the gimbal frame 70 and the movable body 5 in a manner that allows rotation about a first axis R1. The second connecting mechanism 72 connects the gimbal frame 70 and the housing 19 in a manner that allows rotation about a second axis R2. When the gimbal mechanism 7 is configured, the movable body 5 can swing around the intersection point of the optical axis L, the first axis R1, and the second axis R2, i.e., the swing center P (see reference). Figure 3 It oscillates around the center.

[0055] The universal joint frame 70 is constructed of metal leaf springs. For example... Figure 1 , Figure 2 As shown, the gimbal frame 70 includes: a gimbal frame main body 74 having an opening 73 in which a lens barrel 4a is disposed; a pair of first gimbal frame extension parts 75 protruding from the gimbal frame main body 74 in the direction of the first axis R1 and extending in the -Z direction; and a pair of second gimbal frame extension parts 76 protruding from the gimbal frame main body 74 in the direction of the second axis R2 and extending in the -Z direction.

[0056] The first connecting mechanism 71 consists of a universal joint frame receiving member 16 fixed to a diagonal portion of the first axis R1 direction of the retainer 15 and a pair of first universal joint frame extension portions 75. Each universal joint frame receiving member 16 has a convex curved surface protruding radially inward (not shown). On the other hand, as Figure 2 As shown, each of the first universal joint frame extension parts 75 has a concave surface 77 recessed radially inward at its front end. The first connecting mechanism 71 is constructed by inserting the first universal joint frame extension part 75 into the gap between each universal joint frame receiving part 16 and the retainer 15 and making the convex surface and the concave surface 77 in point contact.

[0057] The second connecting mechanism 72 consists of a universal frame receiving member 16 fixed to a diagonal portion along the second axis R2 of the housing 19 and a pair of second universal frame extension portions 76. Each universal frame receiving member 16 has a convex surface protruding radially inward (not shown). On the other hand, each first universal frame extension portion 75 has a concave surface 77 recessed radially inward. The second connecting mechanism 72 is constructed by inserting the second universal frame extension portions 76 into the gap between each universal frame receiving member 16 and the housing 19, making point contact between the convex and concave surfaces.

[0058] (Jitter correction drive mechanism)

[0059] When constituting the universal joint mechanism 7, such as Figure 4 As shown, a first magnet 61X fixed to the side of the movable body 5 in the -Y direction and a first coil 62X fixed to the housing 19 constitute a first jitter correction drive mechanism 6X. Therefore, by supplying power to the first coil 62X, the movable body 5 rotates about the X-axis. Furthermore, a second magnet 61Y fixed to the side of the movable body 5 in the -X direction and a second coil 62Y fixed to the housing 19 constitute a second jitter correction drive mechanism 6Y. Therefore, by supplying power to the second coil 62Y, the movable body 5 rotates about the Y-axis.

[0060] (Flexible printed circuit board)

[0061] like Figure 2 As shown, the flexible printed circuit board 9 includes: a first portion 91 disposed at a position away from the movable body 5 in the +X direction; and a second portion 92 connecting the movable body 5 and the first portion 91. The first portion 91 includes: a first printed circuit board 93 and a second printed circuit board 94; and a connecting portion 95 connecting the first printed circuit board 93 and the second printed circuit board 94. Figure 3 As shown, the second printed circuit board 94 is disposed inside the wiring storage portion 22, and the first printed circuit board 93 is disposed outside the wiring storage portion 22. The connecting portion 95 extends out from the gap between the housing 19 and the base 20 to the outside of the housing 19 and is connected to the first printed circuit board 93.

[0062] The first part 91 has a fixing portion that is fixed to the fixing body 8. The first printed circuit board 93 has a terminal portion for connecting to a host device that is equipped with an optical unit 1 with jitter correction function. Therefore, the first printed circuit board 93 is indirectly fixed to the fixing portion of the fixing body 8 via a connector (not shown) of the host device. Alternatively, a substrate fixing portion for fixing the first printed circuit board 93 or the second printed circuit board 94 may be provided on the fixing body 8. In this case, the first part 91 has a fixing portion that is directly fixed to the fixing body 8.

[0063] In the first portion 91 of the flexible printed circuit board 9, the connecting portion 95 is a flexible substrate comprising a base film made of polyimide resin, a wiring layer disposed on the surface of the base film, and a cover film covering the wiring layer. On the other hand, the first printed circuit board 93 and the second printed circuit board 94 are rigid substrates. Furthermore, the second portion 92 of the flexible printed circuit board 9 is a flexible substrate with the same structure as the connecting portion 95.

[0064] like Figure 3 As shown, the connecting portion 95 and the second portion 92 are composed of a multilayer substrate 90 formed by stacking multiple substrates. The multilayer substrate 90 includes a first substrate 901 and a second substrate 902 composed of a flexible substrate with the structure described above. The first substrate 901 and the second substrate 902 are stacked in a separated state. Both the first substrate 901 and the second substrate 902 are double-sided substrates with wiring layers provided on both sides of the base film. In addition, the multilayer substrate 90 is not limited to a 2-layer stacked structure, but may also be a 3-layer or higher stacked structure. Furthermore, the first substrate 901 and the second substrate 902 may also be structures in which wiring layers are formed only on one side.

Figure 2 , Figure 3 , Figure 5 As shown, the second portion 92 of the flexible printed circuit board 9 includes: an extension portion 96 connected to the camera module 4, extending in the +X direction through a notch 13 in the first frame portion 14; and a flexure portion 99 extending along the first frame portion 14 of the retainer 15 in the Y-axis direction. The extension portion 96 connects the camera module 4 and the flexure portion 99.

[0066] like Figure 3 , Figure 6 , Figure 7 As shown, the lead-out portion 96 includes a first planar portion 101 extending from the substrate 3 disposed at the bottom of the camera module 4 in the +X direction. Furthermore, the lead-out portion 96 includes: a raised portion 97 extending along the Z-axis direction from the +X end of the first planar portion 101; and a second planar portion 98 extending in the +X direction from the +Z end of the raised portion 97 and connected to the flexible portion 99. A reinforcing plate 100 extending along the Y-axis direction is fixed to the raised portion 97.

[0067] The flexural portion 99 is alternately formed with a folding portion that folds back from one side to the other in the Y-axis direction and a folding portion that folds back from the other side to one side in the Y-axis direction, forming a meandering shape that meanders in the Y-axis direction while extending in the Z-axis direction. In this specification, the meandering shape includes not only the shape of the folding portion that folds back into a curved shape, but also the shape of the folding portion that folds back into an acute-angled shape.

[0068] The upright portion 97 is held in place by the reinforcing plate 100 to the first frame portion 14 of the retainer 15. For example... Figure 3 , Figure 5 As shown, the upright portion 97 is disposed inside the notch 13 provided in the first frame portion 14. (As indicated...) Figure 5 , Figure 7 As shown, a pair of grooves 43 facing each other in the Y-axis direction are provided on the inner side of the notch 13. The two ends of the reinforcing plate 100 in the Y-axis direction protrude from the upright portion 97 towards both sides in the Y-axis direction and are disposed in the pair of grooves 43. Each groove 43 extends in the Z-axis direction and opens in the -Z direction. Furthermore, a conical surface 44 is provided on the inner surface of the -Z-direction end of each groove 43, and this conical surface 44 is inclined in the direction in which the groove width increases towards the -Z direction (see reference). Figure 7 ).

[0069] like Figure 7 As shown, a first guide surface 41 extending along the Z-axis in the -X direction of a pair of grooves 43 and a second guide surface 42 extending from the end of the first guide surface 41 in the +Z direction toward the +X direction are provided on the inner side of the notch portion 13. The notch portion 13 has a recess 40 formed by cutting away the inner side of the protrusion 18 provided in the first frame portion 14, and the first guide surface 41 and the second guide surface 42 are the inner side surfaces of the recess 40.

[0070] When assembling the movable body 5, the camera module body 4b is inserted into the inside of the retainer 15 from the -Z direction, and the lead-out portion 96 of the flexible printed circuit board passes through the notch 13 provided in the first frame portion 14. At this time, the upright portion 97 is inserted into the recess 40 from the -Z direction, and the two ends of the reinforcing plate 100 are inserted into a pair of slots 43 from the -Z direction. Then, the second flat portion 98 and the upright portion 97 are moved into the +Z direction until the second flat portion 98 connected to the +Z direction end of the upright portion 97 contacts the second guide surface 42.

[0071] like Figure 5 As shown in (b), the groove width in the X-axis direction of the groove 43 is greater than the thickness of the reinforcing plate 100. The reinforcing plate 100 contacts the inner surface of the groove 43 in the +X direction. The upright portion 97 is held between the reinforcing plate 100 and the first guide surface 41. Furthermore, the second planar portion 98 is positioned in the Z-axis direction by contacting the second guide surface 42. Figure 3As shown, the second planar portion 98 is positioned on an imaginary surface S that includes the swing center P of the movable body 5 and is perpendicular to the Z-axis.

[0072] (Flexural region)

[0073] The flexural portion 99 is a meandering shape that folds back twice in the opposite direction along the Y-axis. For example... Figure 6 , Figure 7 , Figure 8 As shown, the flexural portion 99 includes a first straight portion 991 extending along the Y-axis direction, a second straight portion 992 overlapping the first straight portion 991 in the -Z direction, and a third straight portion 993 overlapping the second straight portion 992 in the -Z direction. The first straight portion 991 is disposed on the same surface as the second planar portion 98 (i.e., on the imaginary surface S). The portion where the second planar portion 98 connects to the first straight portion 991 has a curved shape within the same plane.

[0074] The flexural portion 99 is bent into a Z-shape when viewed from the X-axis direction. Therefore, the first straight portion 991 and the third straight portion 993 are parallel to the XY plane, and the second straight portion 992 is inclined relative to the XY plane. The flexural portion 99 includes: a first folding portion 994 that folds back from the +Y direction end of the first straight portion 991 towards the -Y direction at an acute angle; and a second folding portion 995 that folds back from the -Y direction end of the second straight portion 992 towards the +Y direction at an acute angle.

[0075] like Figure 3 , Figure 8 As shown, in this embodiment, the second planar portion 98 and the first straight portion 991 are located on an imaginary plane S that includes the swing center P of the movable body 5 and is perpendicular to the Z-axis. The flexural portion 99 meanders along the Y-axis direction from the position of the imaginary plane S and extends along the -Z direction.

[0076] In addition, in this embodiment, such as Figure 8 As shown, when viewed from the X-axis direction, the center of the lead-out portion 96 in the Y-axis direction overlaps with the optical axis L. Therefore, the center of the lead-out portion 96 in the Y-axis direction is at the same position as the swing center P in the Y-axis direction. More specifically, the first planar portion 101, the upright portion 97, and the second planar portion 98 constituting the lead-out portion 96 are each at the same position as the swing center P in the Y-axis direction.

[0077] (The main effects of this implementation method)

[0078] As described above, the optical unit 1 with jitter correction function in this embodiment includes: a movable body 5 having a camera module 4; a fixed body 8; a gimbal mechanism 7, which acts as a swing support mechanism, supporting the movable body 5 so that it can swing relative to the fixed body 8 about an X-axis (about a first swing axis) intersecting the optical axis L, and supporting the movable body 5 so that it can swing about a Y-axis (about a second swing axis) intersecting the optical axis L and the X-axis; a jitter correction drive mechanism 6, which causes the movable body 5 to swing about the X-axis (about the first swing axis) and to swing about the Y-axis (about the second swing axis); and a flexible printed circuit board 9 extended from the movable body 5. The flexible printed circuit board 9 includes: a first portion 91 disposed at a position away from the movable body 5 in the +X direction (on one side of the first direction); and a second portion 92 connecting the movable body 5 and the first portion 91. The first portion 91 has a fixing part that is directly or indirectly fixed to the fixed body 8. The second part 92 has a flexural portion 99 that meanders in the Y-axis direction (second direction) and extends in the Z-axis direction (optical axis direction).

[0079] In this embodiment, the flexible printed circuit board 9 connected to the movable body 5 has a flexural portion 99 in the +X direction (one side of the first direction) of the movable body 5, which meanders in the Y-axis direction (second direction) and extends in the optical axis direction (Z-axis direction). Therefore, the straight portions of the flexural portion 99 extending in the Y-axis direction (second direction) are arranged in multiple overlapping configurations in the optical axis direction (Z-axis direction). Thus, when the movable body 5 rotates in the direction about the X-axis (deflection direction), the straight portions extending in the Y-axis direction (second direction) tend to tilt. Furthermore, when the movable body 5 rotates in the direction about the Y-axis (pitch direction), the flexural portion 99 as a whole tends to extend and retract in the optical axis direction (Z-axis direction). Therefore, when the movable body 5 rotates in either the X-axis (about the first swing axis) or the Y-axis (about the second swing axis), the spring constant of the flexible printed circuit board 9 during deformation is small, resulting in a small swing load on the movable body 5. Furthermore, since the flexible portion 99 can be arranged along the side of the movable body 5 in the X-axis direction (first direction), the arrangement space only needs to accommodate the width of the flexible printed circuit board 9 extending in the Y-axis direction (second direction). Therefore, the width of the arrangement space in the X-axis direction (first direction) is small. As a result, the length of the wiring storage portion 22 that houses the flexible portion 99 in the X-axis direction can be reduced, thus enabling the miniaturization of the optical unit 1 with jitter correction function.

[0080] In this embodiment, the second portion 92 of the flexible printed circuit board 9 includes an extension portion 96 connecting the movable body 5 and the flexible portion 99. The extension portion 96 includes a raised portion 97 extending along the optical axis (Z-axis direction), and the flexible portion 99 is connected to the extension portion 96 on an imaginary plane S containing the pivot center P of the movable body 5 and perpendicular to the optical axis L. Thus, by providing the raised portion 97 between the movable body 5 and the flexible portion 99, the flexible printed circuit board 9, extended from any position of the movable body 5, can be wound to a position at the same height as the pivot center P of the movable body 5. In this embodiment, the connection point between the flexible portion 99 and the extension portion 96 is located at the same position as the pivot center P of the movable body 5 along the optical axis (Z-axis direction).

[0081] Therefore, in either the case of the movable body 5 rotating in the direction of the X-axis (deflection direction) or rotating in the direction of the Y-axis (pitch direction), the displacement of the connection between the flexure 99 and the lead-out portion 96 in the optical axis direction (Z-axis direction) is small. If the connection between the flexure 99 and the lead-out portion 96 is displaced in the optical axis direction (Z-axis direction), the displacement of both ends of the flexure 99 in the Y-axis direction (second direction) increases accordingly, and the maximum displacement of the flexure 99 increases. In this embodiment, since the displacement of the connection between the flexure 99 and the lead-out portion 96 in the optical axis direction is small, the maximum displacement of the flexure 99 is small. As a result, the height of the wiring storage portion 22 that houses the flexure 99 in the Z-axis direction can be reduced, and thus, the optical unit 1 with jitter correction function can be miniaturized. Alternatively, it is possible to prevent the flexure 99 from colliding with the fixed body 8 when the movable body 5 swings. Therefore, damage to the flexible printed circuit board 9 can be avoided, and the increase in oscillation load caused by the obstruction of the deformation of the flexible printed circuit board 9 can be suppressed.

[0082] In this embodiment, the lead-out portion 96 includes a second planar portion 98 extending from the upright portion 97 in the +X direction, but it may also omit the second planar portion 98. That is, the upright portion 97 may be directly connected to the edge of the first straight portion 991 of the flexible portion 99 in the -X direction.

[0083] In this embodiment, the center of the lead-out portion 96 in the Y-axis direction (second direction) is at the same position as the swing center P in the Y-axis direction (second direction). More specifically, the first planar portion 101, the upright portion 97, and the second planar portion 98 constituting the lead-out portion 96 all overlap with the optical axis L when viewed from the X-axis direction (see reference). Figure 8 The position along the Y-axis is the same as the center of oscillation P. Therefore, as... Figure 8As shown, the connection between the flexure 99 and the lead-out portion 96 overlaps with the swing center P when viewed from the X-axis direction. Therefore, when the movable body 5 rotates in the X-axis direction (deflection direction), the connection between the flexure 99 and the lead-out portion 96 will not displace in the optical axis direction (Z-axis direction). Thus, the maximum displacement of the flexure 99 can be reduced. Furthermore, the connection between the flexure 99 and the lead-out portion 96 separates from both ends of the flexure 99. Therefore, when the movable body rotates in the Y-axis direction (pitch direction), the displacement at both ends of the flexure 99 can be reduced. Therefore, the maximum displacement of the flexure 99 can be reduced, enabling miniaturization of the optical unit 1 with jitter correction function. Alternatively, collisions between the flexure 99 and the fixed body 8 can be avoided when the movable body 5 swings. Therefore, damage to the flexible printed circuit board 9 can be avoided, and the increase in swing load caused by the obstruction of deformation of the flexible printed circuit board 9 can be suppressed.

[0084] In this embodiment, the flexural portion 99 extends along the Y-axis direction (second direction) and folds back twice in the opposite direction. In this way, the flexural portion 99 can easily flex in either the case of the movable body 5 rotating in the direction about the X-axis (deflection direction) or rotating in the direction about the Y-axis (pitch direction).

[0085] Furthermore, the flexural portion 99 only needs to be bent back at least twice in the Y-axis direction, and the number of bending backs can be three or more. By increasing the number of bending backs, the deformability of the flexural portion 99 is improved, thus reducing the spring constant.

[0086] In this embodiment, the total number of the first folding portion 994 folding back from the -Y direction to the +Y direction and the second folding portion 995 folding back from the +Y direction to the -Y direction of the flexural portion 99 is 2, which is an even number. As described above, when the number of folding backs is greater than 2, it is preferable to set it to an even number. If the total number of folding backs is even, the portion on one side of the flexural portion 99 in the Y-axis direction (second direction) and the portion on the other side of the flexural portion 99 in the Y-axis direction (second direction) deform in a balanced and good manner when the movable body 5 rotates. Therefore, it is possible to avoid the swing load of the movable body 5 changing due to the direction of rotation. Therefore, tilt control of the movable body 5 becomes easier.

[0087] In this embodiment, the first fold-back portion 994, which folds back from the -Y direction to the +Y direction, and the second fold-back portion 995, which folds back from the +Y direction to the -Y direction, are both folded back into acute angles, and the flexible portion 99 is bent into a Z-shape. The fold-back portion folded back into an acute angle shape is easy to open and close in the optical axis direction. Therefore, by forming the flexible portion 99 into a Z-shape, the spring constant of the flexible printed circuit board 9 can be reduced, and the swing load of the movable body 5 can be reduced.

[0088] In this embodiment, the flexible portion 99 includes a first substrate 901 and a second substrate 902 stacked in a separated state. Furthermore, the first substrate 901 and the second substrate 902 are double-sided substrates. Therefore, although it has a large wiring area, the spring constant of the flexible printed circuit board 9 is small.

[0089] In this embodiment, the lead-out portion 96 includes: a first planar portion 101 extending from the camera module 4 in the +X direction (one side of the first direction); an upright portion 97 extending from the first planar portion 101 in the +Z direction (one side of the optical axis direction); and a second planar portion 98 extending from the end of the upright portion 97 in the +Z direction (one side of the optical axis direction) in the +X direction (one side of the first direction) and connected to the flexible portion 99. The movable body 5 includes a retainer 15 surrounding the camera module 4, the lead-out portion 96 passes through a notch 13 provided in the retainer 15, and the upright portion 97 is disposed inside the notch 13. A pair of grooves 43 opposite each other in the Y-axis direction (second direction) are provided on the inner side of the notch 13, and a reinforcing plate 100 protruding from both sides of the upright portion 97 in the Y-axis direction (second direction) and embedded in the grooves 43 is fixed to the upright portion 97. Therefore, since the upright portion 97 can be arranged inside the notch 13, it is not necessary to ensure space for the upright portion 97 outside the movable body 5. This reduces the space required for the flexible printed circuit board 9, allowing for miniaturization of the optical unit 1 with jitter correction function. Furthermore, since the lead-out portion 96 can be easily held on the retainer 15, the assembly of the movable body 5 is excellent. Moreover, since the lead-out portion 96 can be positioned relative to the retainer 15 via the reinforcing plate 100, the flexible portion 99 can be positioned appropriately via the lead-out portion 96. For example, the flexible portion 99 and the lead-out portion 96 can be connected on an imaginary plane S containing the swing center P of the movable body 5 and perpendicular to the optical axis L.

[0090] In this embodiment, the inner surface of the notch 13 includes: a first guide surface 41 extending in the -X direction (the other side of the first direction) along the optical axis direction (Z-axis direction) relative to the pair of grooves 43; and a second guide surface 42 extending from the end of the first guide surface 41 in the +Z direction (one side of the optical axis direction) toward the +X direction (one side of the first direction). The upright portion 97 is disposed between the first guide surface 41 and the reinforcing plate 100, and the second flat portion 98 contacts the second guide surface 42. In this way, the upright portion 97 and the second flat portion 98 can be positioned using the first guide surface 41 and the second guide surface 42, thus providing good assemblability when assembling the movable body 5. In addition, the second flat portion 98 can be positioned in the optical axis direction (Z-axis direction), and the flexible portion 99 can be disposed at an appropriate position in the optical axis direction (Z-axis direction) via the second flat portion 98. For example, the flexible portion 99 and the lead-out portion 96 can be connected on an imaginary plane S that includes the swing center P of the movable body 5 and is perpendicular to the optical axis L.

[0091] (Example of a deformed flexure)

[0092] Figure 9 This is a perspective view of the flexible printed circuit board 9A and the camera module 4 in a modified example. In the flexible printed circuit board 9 of the above embodiment, the first folded-back portion 994 and the second folded-back portion 995 are folded back into an acute angle shape, and the flexural portion 99 is generally folded back into a Z-shape, but the shape of the flexural portion 99 is not limited to a Z-shape.

[0093] like Figure 9 As shown, in the modified flexible printed circuit board 9A, the flexural portion 99A includes a first folded-back portion 994A and a second folded-back portion 995A that are bent back in a curved shape. Both the first folded-back portion 994A and the second folded-back portion 995A are bent into a semi-circular shape. Therefore, the second straight portion 992 extends parallel to the first straight portion 991 and the third straight portion 993.

[0094] The modified example's flexible portion 99A includes a shape-holding member 102 that maintains the shape of the first folded-back portion 994A and the second folded-back portion 995A. For example... Figure 9 As shown, the shape-retaining member 102 is a spacer disposed between the first straight portion 991 and the second straight portion 992, and between the second straight portion 992 and the third straight portion 993. Thus, by folding back the folded portion in a bent shape while clamping the spacer, it is possible to prevent the folded portion from opening due to the springback of the flexible printed circuit board. Therefore, it is possible to avoid the inability to maintain the shape of the flexural portion 99, and the shape of the flexural portion 99 is easily maintained. Therefore, the movable body 5 has good assemblability.

[0095] (Other implementation methods)

[0096] The above-described embodiment is a method of correcting jitter around two axes by swinging the movable body 5 in the pitch and yaw directions.
