[0027] like Figure 1As shown, a camera device 101, including an optical component driving device 100 as one embodiment of the present invention, is housed within the frame of a smartphone 109. The camera device 101 includes an AF (Auto Focus) motor 102 as a lens device, an image sensor 107 as an optical component, and the optical component driving device 100. The AF motor 102 has a lens body 110 and an actuator that drives the lens body 110 in a direction parallel to the optical axis of the lens body 110. The image sensor 107 converts light transmitted through the lens body 110 into an image signal and outputs it. The optical component driving device 100 fixes the AF motor 102 and the image sensor 107, and drives the image sensor 107 in a direction orthogonal to the optical axis of the lens body 110 of the AF motor 102 and in a direction rotating about the optical axis. Alternatively, as a lens device, it may not have an actuator that drives in a direction parallel to the optical axis of the lens body 110.

[0028] Hereinafter, the optical axis direction of the lens body 110 is appropriately referred to as the Z direction, a direction orthogonal to the Z direction is appropriately referred to as the X direction, and a direction orthogonal to both the Z and X directions is appropriately referred to as the Y direction. When viewed from the lens body 110, the +Z side, which is the side of the subject, is sometimes referred to as the front side, and the -Z side, which is the opposite side (the image sensor 107 side), is referred to as the rear side.

[0029] like Figure 3 As shown, the optical component driving device 100 includes a housing 1, four suspension wires 2, four support leaf springs 3, a bracket 4, four magnets 5, a coil substrate 6, an FPC (Flexible Printed Circuit) 7, four driver ICs 8, and a base plate 9. Among these components, the housing 1 and the base plate 9 are combined as a frame, which houses the suspension wires 2, support leaf springs 3, brackets 4, magnets 5, coil substrate 6, FPC 7, and driver ICs 8.

[0030] The housing 1, base plate 9, bracket 4, and magnet 5 constitute the fixed part, while the coil substrate 6, FPC 7, and driver IC 8 constitute the movable part. A support spring 3 and suspension wire 2 connect the fixed part and the movable part and support the movable part. The AF motor 102 is housed and fixed within the storage space formed by the bracket 4, which constitutes the frame of the fixed part. The image sensor 107 is mounted on a sensor substrate (not shown), and the sensor substrate is fixed to the rear surface of the FPC 7, which constitutes the movable part. The rear surface of the FPC 7 is a holding part that holds the image sensor 107.

[0031] like Figure 6As shown, the coil substrate 6 has a body portion 600 and a first blocking portion 610 and a second blocking portion 620 protruding outward from the periphery of the body portion 600. A rectangular through hole 69 is provided in the center of the body portion 600 of the coil substrate 6, and both its outer and inner shapes form a quadrilateral with four corner rings. Two coils 65 are provided on each side of the quadrilateral of the body portion 600.

[0032] FPC7 is a component formed by folding a thin plate with point symmetry to create a three-dimensional shape. FPC7 has a body portion 70 and two connecting portions 71 arranged with point symmetry. A rectangular through hole 79 is provided in the center of the body portion 70 of FPC7, forming a four-cornered ring with both the outer and inner shapes being quadrilaterals. A coil substrate 6 is fixed to the front surface of the body portion 70.

[0033] like Figure 7 As shown, for the two connecting portions 71 of the FPC7, the base end portion 73 rises forward from a predetermined position on the +X and -X sides of the body portion 70. The base end portion 73 of the connecting portion 71 of the FPC7 faces the side of the body portion 600 of the coil substrate 6 and is sandwiched with adhesive. That is, the base end portion 73 is bonded and fixed to the coil substrate 6 by adhesive. The adhesive can also be extruded forward from the gap between the base end portion 73 of the FPC7 and the periphery of the coil substrate 6. The predetermined position is a corner near a predetermined diagonal, which is the corner on the +X+Y side and the corner on the -XY side. The connecting portion 71 extends along each side toward the side opposite to the predetermined diagonal, and when it reaches the corner of the adjacent side, it extends along the adjacent side and falls backward at a predetermined position. This predetermined position is a corner near the other side of the predetermined diagonal. The rearward-folding connecting portion 71 bends outward in the Y direction at the same height as the base plate 9, protruding outward through the gap between the rear edge of the housing 1 and the base plate 9. Thus, the FPC7 covers the outer side of the bracket 4, except for the designated diagonal portions. Figure 4 As shown, the rear edge of the portion extending along the two sides of the connecting portion 71 is located entirely in front of the coil substrate 6.

[0034] The front end of the portion of the connecting part 71 protruding outward from the housing 1 is T-shaped, and multiple connection terminals are provided on the rear surface of this T-shaped portion. A driver IC8 is provided on each side of the quadrilateral of the main body 70, and the driver IC8 is fixed to the rear surface of the FPC7 at a position directly behind the coil 65 near a predetermined diagonal side of the quadrilateral. Additionally, a sensor substrate on which an image sensor 107 is mounted is mounted on the rear surface of the main body 70, and the light-receiving surface of the image sensor 107 is exposed to the front through the through-hole 79. The coil 65 and the image sensor 107 are electrically connected to the main body of the smartphone 109 via the FPC7.

[0035] As described above, the first barrier portion 610 and the second barrier portion 620 are provided so as to protrude outward from the peripheral edge of each side portion of the body portion 600 of the coil substrate 6. Each of the first barrier portion 610 and the second barrier portion 620 directly faces the inner surface of the housing 1. In contrast, between the outer peripheral surface of the body portion 600 of the coil substrate 6 and the inner surface of the housing 1, there are the base end portion 73 of the connecting portion 71 of the FPC 7 and the portion where the connecting portion 71 is bent. The two barrier portions 610 and 620 protrude outward from the portions where the FPC 7 is not present in the outer periphery. The base end portion 73 faces the side surface of the body portion 600 of the coil substrate 6 and is located inward of the outer side end of the two barrier portions 610 and 620. The first barrier portion 610 is provided between the other diagonal that is not the prescribed diagonal and the portion immediately before the FPC 7 is present in the outer periphery, and the second barrier portion 620 is provided between the prescribed diagonal and the portion immediately before the FPC 7 is present in the outer periphery. When the movable portion moves in the XY directions and rotates around the Z axis, the first barrier portion 610 and the second barrier portion 620 come into contact with the inner surface of the housing 1 before any other portion of the movable portion. Therefore, it is preferable that the first barrier portion 610 and the second barrier portion 620 be provided near the corners. The functions of the first barrier portion 610 and the second barrier portion 620 as barrier members can be exerted by only one of them. However, by adopting a configuration in which the base end portion 73 of the FPC 7 is sandwiched between the first barrier portion 610 and the second barrier portion 620, it is possible to prevent the base end portion 73 from coming into contact with the inner surface of the housing 1 before the first barrier portion 610 and the second barrier portion 620 when the movable portion moves. In addition, on the rear surface of the second barrier portion 620, an electrical connection portion 621 that electrically connects the body portion 70 of the FPC 7 is provided.

[0036] The bracket 4 is a frame-shaped body that is quadrangular when viewed in the Z direction and has two pairs of wall portions 41 that face in the X and Y directions. At the corners where the wall portions 41 intersect, there are cutouts 43 that are semicircular on the inner side. On the front surface of the wall portion 41, there is a step portion 480 that protrudes forward from the corner toward the center of the side portion in two stages. The step portion 480 has a frontmost surface 481 in the center and two middle surfaces 482 on the sides thereof.

[0037] In the center of the frontmost surface 481 of the step portion 480 of the wall portion 41 that faces in the Y direction, there is a positioning protrusion 413, and on the X direction sides of the positioning protrusion 413, there are two protrusion portions 414. The positioning protrusion 413 directly rises from a groove that is formed annularly around it. The frontmost surface 481 of the step portion 480 of the wall portion 41 that faces in the X direction is divided into two sides by a pit portion 420 in the center, and on the Y direction sides of the pit portion 420, there are two protrusion portions 414. In addition, on the eight middle surfaces 482 of the step portion 480 of the wall portion 41, there are small protrusions 46, respectively.

[0038] As Figure 2As shown, the bracket 4 is covered by the case 1. The case 1 is box-shaped, having a front plate 10 which is a quadrangle when viewed in the Z direction, and side plates 11 which extend from the edges of the front plate 10 to the rear side. In the center of the front plate 10 of the case 1 which covers the front side of the bracket 4, a rectangular through-hole 19 is provided. The shape and size of the through-hole 19 are substantially the same as those of the inner shape of the wall portion 41 of the bracket 4. When the AF motor 102 is housed in the bracket 4, the front side of the AF motor 102 is exposed from the through-hole 19. On the front plate 10, at the central positions of the edges of the quadrangle, recessed portions 180 are provided which are recessed toward the rear side. On each of the recessed portions 180, two through-holes 14 are provided along the edge. On the recessed portions 180 on the +X side and the -X side, positioning holes 13 are further provided which are located at the center between the two through-holes 14.

[0039] The positioning protrusion 413 of the bracket 4 is fitted into the positioning hole 13 of the front plate 10 of the case 1. At this time, the rear surface of the table portion 480 and the recessed portion 180 abut, and the rear surface of the recessed portion 180 is difficult to float with respect to the table portion 480 by the groove around the positioning protrusion 413. The protrusion portion 414 of the bracket 4 is inserted into the through-hole 14 of the front plate 10 of the case 1 and is fixed by heat caulking. As shown in Figure 5 As shown, the width of the front side protrusion portion 414 of the through-hole 14 in the protrusion portion 414 is wider than the width of the through-hole 14, so the bracket 4 is difficult to fall off from the case 1. The width being wide corresponds to the diameter being large in the case where the cross section after heat caulking is circular. In addition, the front end of the protrusion portion 414 is located at a position which is on the rear side from the front plate 10 of the portion adjacent to the recessed portion 180.

[0040] As shown in Figure 4 and Figure 8 As shown, on the inner side surface of the wall portion 41 of the bracket 4, a eave portion 45 is provided. The eave portion 45 is provided with a first protrusion portion which protrudes inward from the rear end of the inner side surface of the wall portion 41, and protrudes toward the rear side from the inner end thereof. The AF motor 102 is housed in the space surrounded by the inner side surface of the wall portion 41 and the front surface of the eave portion 45 in the bracket 4. The outer surface of the AF motor 102 is adhesively fixed to the inner side surface of the wall portion 41.

[0041] The rear surface of the wall portion 41 of the support 4 is bonded and fixed to the front surface of the magnet 5. The magnet 5 is an elongated cuboid shape and is disposed along the wall portion 41. A coil substrate 6 is located on the rear side of the magnet 5. The coils 65 on the magnet 5 and the coil substrate 6 face each other at a distance. Preferably, the outer surface of the wall portion 41, which also exists on the outer surface of the support 4, is parallel to the outer surface of the magnet 5, thus forming the same surface. The corners of the outer surfaces of the rear surface of the support 4, which serve as the bonding surface to the magnet 5, are chamfered and have inclined surfaces 453. In addition, the corners of the front surface and the outer surface of the magnet 5, which serve as the bonding surface to the support 4, are chamfered and have inclined surfaces 52. The adhesive between the wall portion 41 and the magnet 5 in the contact surface is squeezed into these chamfered portions, forming adhesive accumulation portions. That is, a sufficient amount of adhesive is supplied between the rear surface of the support 4 and the front surface of the magnet 5, so that excess adhesive can be contained in the space formed by the two inclined surfaces 453, 52. However, the adhesive is not exposed beyond the outer surfaces of the support 4 and the magnet 5. In addition, adhesive is sandwiched between the outer surface facing the first protrusion 451 and the inner surface of the magnet 5, and the magnet 5 is also bonded and fixed by the first protrusion 451. In addition, the magnet 5 has two peripheral end surfaces 51 that intersect with the front surface and the outer surface, and the support 4 has two second protrusions 452 that protrude rearward from the rear surface and sandwich the magnet 5. Adhesive is sandwiched between each peripheral end surface 51 and the opposing surface of the second protrusion 452 opposite to the peripheral end surface 51, and the magnet 5 is also bonded and fixed by the second protrusion 452. In addition, as Figure 5 As shown, at the position where the magnet 5 is bonded and fixed on the rear surface of the bracket 4, there is an adhesive storage part, namely a groove 454, which is recessed to the front side.

[0042] In bracket 4, except for the corner portions on the +X+Y and -XY sides, the portions on the bracket 4 are surrounded by the connecting portion 71 of FPC 7. The corner portions on the +X+Y and -XY sides of bracket 4 are not surrounded by the connecting portion 71 and are exposed to the outside.

[0043] like Figure 3 as well as Figure 4 As shown, the support leaf spring 3 is roughly L-shaped. Circular holes are provided at the base end of the support leaf spring 3 and at the front end extending at a right angle from there.

[0044] The front end of the support leaf spring 3 is fixed on the middle section surface 482 of the platform 480 of the bracket 4. A small protrusion 46 on the middle section surface 482 of the platform 480 is inserted into a circular hole at the front end of the support leaf spring 3. The base end of the support leaf spring 3 is in a floating state on the front side of the cutout 43 of the bracket 4. Circular holes are present at the four corners of the coil substrate 6 at positions corresponding to the circular holes at the front end of the support leaf spring 3.

[0045] The suspension wire 2 is suspended between the circular hole of the base end portion of the support plate spring 3 and the circular hole of the coil substrate 6 through the cutout 43 of the bracket 4. That is, the front end of the suspension wire 2 is inserted and soldered to the circular hole of the base end portion of the support plate spring 3, and the rear end is inserted and soldered to the circular hole of the four corners of the coil substrate 6. In addition, at each corner portion of the prescribed diagonal, that is, the +X+Y side and the X-Y side, the end portion side of the top of each corner portion of the two magnets 5, that is, the peripheral end surface 51, is formed to be perpendicular to each other. Each peripheral end surface 51 and the front surface of the coil substrate 6 facing the movable portion are spanned by a resin having viscoelasticity. The resin having viscoelasticity is so-called damping rubber. The spanned peripheral end surface 51 is the peripheral end surface 51 of the +Y side magnet 5 facing the +X direction, the peripheral end surface 51 of the -Y side magnet 5 facing the -X direction, the peripheral end surface 51 of the +X side magnet 5 facing the +Y direction, and the peripheral end surface 51 of the -X side magnet 5 facing the -Y direction. Thus, for both the X and Y directions, a damping effect can be obtained.

[0046] The above describes the details of the present embodiment. The optical member driving device 100 of the present embodiment includes a fixed portion having a housing 1 that houses an AF motor 102 as a lens device, and a movable portion having a holding portion that holds an image sensor 107, which is supported by a suspension wire 2 at a position behind the AF motor 102. The fixed portion has the housing 1 that surrounds the periphery of the movable portion, and the movable portion has a coil substrate 6 that forms a coil 65, the coil substrate 6 having a body portion 600 and barrier portions 610, 620 that protrude outward from the periphery of the body portion 600, the barrier portions 610, 620 directly facing the inner side surface of the housing 1. Thus, an optical member driving device 100 can be provided in which the barrier portions 610, 620 directly face the inner side surface of the housing 1, do not interfere with the movement of the movable portion, and the movable portion can move smoothly.

[0047] In the above embodiment, the peripheral end surface 51 of the corner portion facing the +X-Y side and the -X-Y side and the front surface of the coil substrate 6 can not be spanned by the resin having viscoelasticity. In addition, the spanned portion need not be the peripheral end surface 51, and can be, for example, a surface of the corner portion of the second protruding portion 452 of the bracket 4 facing the top of the corner portion. In this case, the second protruding portion 452 can extend further to the rear side than illustrated. In addition, the movable portion that is spanned need not be the coil substrate 6, and for example, the FPC 7 can be provided on the front side of the coil substrate 6 and spanned.

[0048] Furthermore, in the above-described embodiment, the protruding portions 414 of the bracket 4 and the through holes 14 of the housing 1 need not be provided two each at each side portion of the through hole 19, but can be provided only at two opposite side portions, or one each or three or more each at each side portion. Also, it is preferable that the number of protruding portions 414 be the same at each side portion on one opposite side portion, but the number of protruding portions 414 can be different between different opposite side portions.

[0049] Also, in the above-described embodiment, for the fixation of the protruding portions 414 of the bracket 4 to the through holes 14 of the housing 1, both rivet fixation and adhesive can be used, and the housing 1 and the bracket 4 can be adhered by the adhesive. In this case, the adhesive is sandwiched between the front surface of the bracket 4 and the rear surface of the front plate 10 of the housing 1.
