[0033] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 As shown, a camera device 8, as an embodiment of the present invention, is housed in a smartphone 9.

[0034] The camera device 8 includes: a lens body 7; blades 11 disposed on the front side of the lens body 7; an image sensor 6 that converts light from the lens body 7 into electrical signals; a lens driving device 5 that drives the lens body 7; and a blade driving device 1 that drives the blades 11.

[0035] Subsequently, the direction in which light from the subject is incident is appropriately called the Z direction, a direction orthogonal to the Z direction is appropriately called the X direction, and a direction orthogonal to both the Z and X directions is appropriately called the Y direction. Additionally, sometimes the +Z side of the optical axis of the lens body 7, which is on the side of the subject, is called the front side, and the side opposite the subject, where the image sensor 6 is located, i.e., the -Z side, is called the rear side. Furthermore, sometimes the +X side is called the upper side, the -X side is called the lower side, the +Y side is called the left side, and the -Y side is called the right side.

[0036] like Figure 3As shown, the lens drive device 5 includes a first cover 50, a gasket 51, four front plate springs 52, an FPC (Flexible Printed Circuits) 60, a lens carrier 70, a bracket 71, a first Hall IC 72, a position detection magnet 73, a counterweight 74, a first coil 75, two rear plate springs 82, a first magnet 85, and a first base 87. In this embodiment, the lens carrier 70, which is a movable part, moves in the Z direction relative to the first base 87, which is a fixed part. The first base 87 is equipped with the first magnet 85, the FPC 60, the first Hall IC 72, and the first cover 50, forming a large fixed part. The first coil 75, the position detection magnet 73, and the counterweight 74 are mounted on the lens carrier 70, forming a large movable body. The lens body 7 and the blade drive device 1 are also mounted on the lens carrier 70. They move in the Z direction together with the lens carrier 70.

[0037] like Figure 4 As shown, the FPC 60 has an external terminal connection portion 64 at one end that connects to the outside of the lens drive device 5, a flat plate portion 62 at the other end, and an internal path portion 61 at the other end of one of the two. A portion of the flat plate portion 62 belongs to the other end of one of the two. A strip-shaped portion 63 extending along the outer periphery of the lens drive device 5 connects the external terminal connection portion 64 and the flat plate portion 62. The lens drive device 5 and the blade drive device 1 are electrically connected to the outside via the FPC 60.

[0038] A connection terminal for external connection is provided at the rear end of the external terminal connection portion 64. A strip-shaped portion 63 extends from the front side of the external terminal connection portion 64 along the -X direction, and at the corner of the lens drive device 5 on the -XY side, extends towards the +Y direction with a change in orientation, reaching the plate portion 62. The plate portion 62 is fixed to the side wall portion 872 of the first base 87 (described later). An internal path portion 61 extends from the +Z side portion of the plate portion 62. The internal path portion 61 forms a four-sided frame shape, with wiring portions 660 formed at the four corners. The -Z side portion of the plate portion 62 protrudes towards the -Y side as a protrusion 65 belonging to the other end of the other side. Three cutouts 670 are provided on the -Z side end edge of the plate portion 62. Wiring portions 680 are provided in the three cutouts 670 on the +Y and -Y sides. Furthermore, the first Hall IC 72 (described later) is fixed to the inner surface of the plate portion 62 located at the other end of the other side.

[0039] The first base 87 and the first cover 50 are combined to form a frame. The image sensor 6 is fixed on the rear surface of the first base 87.

[0040] The lens carrier 70 is housed within the frame. A blade drive device 1 is mounted on the front side of the lens carrier 70. The blade drive device 1 protrudes forward from the through-hole in the first cover 50.

[0041] The lens holder 70 holds the lens body 7 and moves at least in the direction of the optical axis of the lens body 7. For example... Figure 5 As shown, at each position on the front surface of the lens carrier 70 where the lens body 7 is sandwiched between the +Y and -Y sides, there are pairs of metal carrier-side receiving parts 701.

[0042] like Figure 8 As shown, the carrier-side receiving portion 701 is integrally formed with the lens carrier 70 by insertion molding. For a pair of carrier-side receiving portions 701, the two plate-like members are slightly separated and facing each other towards the +X and -X sides. The space between the pair of carrier-side receiving portions 701 is filled with resin that constitutes the body of the lens carrier 70. The pair of carrier-side receiving portions 701 extend forward from the front surface of the lens carrier 70, and the front ends are bent at right angles along the mutually separating directions to form a first surface 702 on the front side. The front ends extending from the first surface 702 also extend forward.

[0043] The first base 87 is a quadrilateral plate-shaped component with a through hole in the center. The body of the first base 87 is formed of resin, with the first metal component 91, the second metal component 92, and the third metal component (not shown) embedded within the resin. The three metal components are formed in a rectangular shape and extend along the four sides of the first base 87. The first metal component 91 and the second metal component 92 have side exposed portions that protrude to the outer side of the -X side of the first base 87. Additionally, the first metal component 91 and the second metal component 92 have front exposed portions that protrude forward.

[0044] like Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, there are column portions 871 at the four corners of the first base 87. There are sidewall portions 872 at the ends of the first base 87 on the -X and +X sides. Figure 3 As shown, a rectangular opening 873 is provided on the side wall portion 872 on the -X side.

[0045] like Figure 3 as well as Figure 7 As shown, on the protrusions on the +Y and -Y sides of the lens carrier 70, the first coil 75 is wound around the Y-axis. On the front surface of the edge portion on the +Y and -Y sides of the first base 87, the first magnet 85 is fixed opposite to the first coil 75. For the first magnet 85, two magnet plates are arranged side by side along the Z-axis and magnetized so that the magnetic poles on the side facing the first coil 75 and the magnetic poles on the opposite side are opposite magnetic poles. In addition, the magnetization directions of the two magnet plates are opposite.

[0046] The front leaf spring 52 is electrically separated into four leaf spring plates: +X+Y side, +XY side, -X+Y side, and -XY side, forming a quadrilateral shape as a whole. Figure 5 As shown, each leaf spring of the front leaf spring 52 has an inner portion 521, an outer portion 522, and a wrist portion 523 that elastically connects them. The rear leaf spring 82 is divided into two leaf springs, a +X side and a -X side, which are electrically separated and are quadrilateral in shape as a whole. Each leaf spring of the rear leaf spring 82 has an inner portion 821, two outer portions 822, and two wrist portions 823 that elastically connect them.

[0047] The lens carrier 70 is supported in the air by a front leaf spring 52 and a rear leaf spring 82. The four inner portions 521 of the front leaf spring 52 are respectively fixed to the periphery of the front side of the lens carrier 70. Figure 8 As shown, the inner portions 521 on the +XY side and the -XY side are respectively configured to contact the bases of the two carrier-side receiving portions 701 on the -Y side of the lens carrier 70, and are electrically connected by solder joints or the like. Similarly, the inner portions 521 on the +X+Y side and the -X+Y side are also respectively configured to contact the bases of the two carrier-side receiving portions 701 on the +Y side of the lens carrier 70, and are electrically connected by solder joints or the like.

[0048] The two inner portions 821 of the rear leaf spring 82 are fixed to the peripheral portion of the rear side of the lens carrier 70. For example... Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the four outer portions 822 of the rear plate spring 82 are fixed to the inner portion of the column portion 871 on the front surface of the first base 87.

[0049] On the rear side of the four outer portions 522 of the front leaf spring 52, the internal path portion 61 of the FPC 60 is disposed, and the outer portions 522 and the wiring portion 660 are electrically connected by soldering or other means. On the front side of the outer portions 522, four corner frame-shaped gaskets 51 are fixed, and the gaskets 51 are fixed to the rear surface of the front sidewall of the first cover 50. The four outer portions 522 of the front leaf spring 52 extend along the X and Y directions with the same width as the internal path portion 61 and the gaskets 51, and these three extend closely along the outer shape of the first cover 50.

[0050] like Figure 3As shown, a first Hall IC 72 is fixed on the inner surface of the flat plate portion 62. The first Hall IC 72 is a magnetic position sensor. Six wiring terminals are provided in the FPC 60 to fix the first Hall IC 72. These six wiring terminals of the FPC 60 are electrically connected to the six solder pads of the first Hall IC 72. Four of the six wiring terminals of the FPC 60 are connected to the external terminal connection portion 64. The remaining two wiring terminals are connected to the wiring portion 680.

[0051] The first Hall IC 72 is housed in the opening 873 of the side wall portion 872 on the -X side of the first base 87. A position detection magnet 73 is fixed on the side of the lens carrier 70 on the -X side, opposite to the first Hall IC 72. A counterweight 74 is fixed on the side of the lens carrier 70 on the +X side. The counterweight 74 is used to achieve weight balance with the position detection magnet 73.

[0052] like Figure 2 As shown, the side exposures of the first metal component 91 and the second metal component 92 extend from the cutout 670 of the FPC60 outwards to the outside of the -X side of the first base 87. The side exposure of the first metal component 91 on the +Y side is soldered to the wiring portion 680 on the +Y side, and the side exposure of the second metal component 92 is soldered to the wiring portion 680 on the -Y side.

[0053] The exposed front portion of the first metal component 91 protrudes into the inner side of the column portion 871 on the -X+Y side of the front of the first base 87, and is soldered to the outer side portion 822 of the rear leaf spring 82 on the -X side. The inner side portion 821 of the rear leaf spring 82 on the -X side is electrically connected to one end of the first coil 75 on the +Y side and the -Y side, respectively.

[0054] The front exposed portion of the second metal component 92 protrudes into the inner side of the column portion 871 on the +XY side of the front of the first base 87, and is soldered to the outer side portion 822 of the rear leaf spring 82 on the +X side. The inner side portion 821 of the rear leaf spring 82 on the +X side is electrically connected to the other end of the first coil 75 on the +Y side and the -Y side, respectively.

[0055] When current is supplied to the first coil 75, an electromagnetic force is generated in the first coil 75 through the magnetic field of the first magnet 85, producing a thrust in the Z direction. This thrust causes the lens carrier 70 of the lens body 7 and the blade drive device 1, supported on its front side, to move in the Z direction against the elastic forces of the front and rear leaf springs 52 and 82. When the current supply to the first coil 75 is stopped, the lens body 7, the lens carrier 70, and the blade drive device 1 return to their original positions.

[0056] The first Hall IC 72 detects the magnetic field of the opposing position detection magnet 73 and outputs a current to drive the first coil 75 based on the detection result. This magnetic field corresponds to the position of the position detection magnet 73 relative to the first Hall IC 72 in the Z direction.

[0057] like Figure 9 , Figure 10 As shown, the blade drive device 1 has a second cover 10, four blades 11, a fixed plate 12, a front coil base 20, four second magnets 21, a movable ring 22, four plate springs 30, a rear coil base 40, a circuit board 41, a second Hall IC 42, and a second base 43.

[0058] In the blade drive device 1, a circuit board 41 is overlapped and fixed on the front side of the second base 43, and a rear coil board 40 is overlapped and fixed on its front side. Additionally, a second magnet 21 is fixed inside the movable ring 22. The column portion of the movable ring 22, erected on the inner circumference of the second base 43, is rotatably supported by a leaf spring 30. The front coil board 20 is fixed to the fixing plate 12 on the rear side, and the fixing plate 12 is fixed to the second base 43 in a manner that covers it. Four blades 11 are mounted on the front side of the fixing plate 12 to connect with the movable ring 22, forming an opening in the center of the four blades 11. Thus, by rotating the movable ring 22, the blades 11 move to change the size of the opening. Furthermore, a second cover 10 is provided to cover the outer portion of the blades 11.

[0059] On the circuit board 41, a second Hall IC 42 is provided to detect the position of the second magnet 21. Additionally, a second coil 121 is embedded in the front coil board 20 and the rear coil board 40, with the second magnet 21 sandwiched between the front and rear of the second coil 121. When current flows through the second coil 121, the magnetic field of the second magnet 21 generates an electromagnetic force in the second coil 121, which, through its reaction, causes the movable ring 22 carrying the second magnet 21 to rotate.

[0060] The second base 43 is formed by inserting and shaping a resin body into which two fourth metal parts 94, two fifth metal parts 95, and two sixth metal parts 96 are embedded.

[0061] The second base 43 is annular. Within the second base 43, on the +X+Y, +XY, -X+Y, and -XY sides of the inner periphery surrounding the central through hole, there are columnar portions 431 rising towards the +Z side. On the +Y and -Y sides of the second base 43, three holes 434 are provided respectively. The three holes 434 are arranged side-by-side along the X direction.

[0062] Each of the fourth metal components 94 has: an exposed portion 941 that protrudes in a hook-like manner along the +X side of the hole 434; an embedded portion 942 that protrudes from the exposed portion 941 toward the +X side in the embedded state, extending to the nearest pillar portion 431 while bending; and an erected portion 943 that stands upright on the pillar portion 431 and extends forward along the pillar portion 431. The front end of the erected portion 943 protrudes and protrudes to the front part of the front edge of the pillar portion 431.

[0063] Each of the fifth metal components 95 has: an exposed portion 951 that protrudes in a hook-like manner along the front and rear in the central hole 434; an embedded portion 952 that extends from the exposed portion 951 toward the outer periphery when embedded; and a blade-side receiving portion 953 that protrudes toward the outer edge of the second base 43 after being stepped up at the front end of the embedded portion 952.

[0064] Each of the sixth metal components 96 has: an exposed portion 961 that protrudes in a hook-like manner along the front and rear of the hole 434 on the -X side; an embedded portion 962 that extends from the exposed portion 961 toward the outer periphery when embedded; and a blade-side receiving portion 963 that protrudes toward the outer edge of the second base 43 after being raised in a stepped manner at the front end of the embedded portion 962.

[0065] The upright portions of the blade side receiving portions 953 and 963 are covered along the X direction by the horizontally elongated thin plate portion 439, and the blade side receiving portions 953 and 963 protrude outward from the side of the thin plate portion 439.

[0066] Four exposed portions 951 and 961 are electrically connected to the second Hall IC 42 via the circuit board 41. One side of the output current of the second Hall IC 42 is supplied from the circuit board 41 to the second coil 121 of the rear coil board 40. The other side of the output current of the second Hall IC 42 flows from the circuit board 41 through the exposed portion 941 into the fourth metal member 94, and is electrically connected to the second coil 121 of the front coil board 20 at the front end of the erected portion 943.

[0067] like Figure 8 As shown, the blade-side receiving portions 953 and 963, protruding from the cutouts 120 on the +Y and -Y sides of the blade drive device 1, are shaped like plate surfaces facing the front-to-back direction. The rear surface, i.e., the second surface 970, is respectively mounted on the first surface 702 of the two carrier-side receiving portions 701 on the +Y and -Y sides of the lens carrier 70. The carrier-side receiving portions 701, blade-side receiving portions 953, and blade-side receiving portions 963 are fixed and electrically connected by welding or soldering. By providing such first surfaces 702 and second surfaces 970, the carrier-side receiving portions 701 can stably support the blade-side receiving portions 953 and 963.

[0068] The above are the details of this embodiment. The camera device 8 in this embodiment includes a lens driving device 5 and a blade driving device 1. The lens driving device 5 includes: a lens carrier 70 that holds the lens body 7; a conductive front leaf spring 52 having an inner portion 521 fixed to the lens carrier 70, an outer portion 522 fixed to a fixing portion disposed on the outer side of the lens carrier 70, and a wrist portion 523 connecting the inner portion 521 and the outer portion 522; and an FPC 60, one end of which is externally connected to the lens driving device 5. The blade driving device 1 is mounted on the lens carrier 70 and drives the blades 11 disposed on the front side of the lens body 7. One end of one side of the FPC 60 is electrically connected to the outer portion 522 of the front leaf spring 52, the inner portion 521 of the front leaf spring 52 is electrically connected to the blade driving device 1, and the other end of the other side of the FPC 60 is used to drive the lens carrier 70. By using an FPC60, with one end for external connection and one end for the blade drive device and the other for the lens mount, it can be easily configured for external connection. Thus, a camera device 8 can be provided that can easily ensure the required number of conductive paths for supplying current to the lens drive device 5 and the blade drive device 1.

[0069] Furthermore, in the above embodiment, the second coil 121 can also be fixed on the movable ring 22, and the second magnet 21 can be fixed on the fixed plate 12 or the second base 43. In this case, the second coil 121 can also be fed from the upright portion 943 of the fourth metal part 94 via the plate spring 30.

[0070] Alternatively, the FPC60 may not have the wiring portion 680 on the flat plate portion 62, but only the internal path portion 61 can extend. A second flat plate portion can be provided on the -Z side midway along the extension of the internal path portion 61, and the wiring portion 680 can be provided on this second flat plate portion. Furthermore, the internal path portion 61 does not need to be frame-shaped (ring-shaped); for example, the +X side portion may be omitted.
