The support wire 7 extends along the Z direction (optical axis direction) in the drawing, and one end thereof is fixed to the base member 2 side (the wiring member 20 provided on the base member 2), and the other end is movable. It is fixed to the member 5 side (upper leaf springs 12 and 13 fixed to the movable member 5). The movable member 5 is suspended and supported by a support wire 7, and is supported so as to be movable in the XY direction (direction intersecting the optical axis) by the bending of the support wire 7. In the illustrated example, a plurality (four) of the support wires 7 are provided, one end of the support wire 7 is fixed to the four corners of the base member 2 having a rectangular outer edge in plan view, and the movable member 5 is movable outside thereof. A stopper 2E for limiting the range is provided.

可動部材５には、複数のマグネット４が取り付けられている。図示の例では、可動部材５は、平面視矩形の外縁を有する筒状部材であり、その角部内側にマグネット４を保持するマグネット保持部５Ａを備えている。ここでは、４個のマグネット４のうち２個のマグネット４がコイル３に対向して配備され、他の２個のマグネット４が位置センサ６に対向して配備されている。   A plurality of magnets 4 are attached to the movable member 5. In the illustrated example, the movable member 5 is a cylindrical member having a rectangular outer edge in plan view, and includes a magnet holding portion 5A that holds the magnet 4 inside the corner portion. Here, of the four magnets 4, two magnets 4 are disposed to face the coil 3, and the other two magnets 4 are disposed to face the position sensor 6.

可動部材５には、レンズ枠８が移動自在に支持されている。レンズ枠８は、図示省略したレンズバレルが取り付けられるねじ部８Ａを備えた円筒部材であり、外周に設けられるコイル保持部８Ｂにフォーカスコイル９が巻回されている。レンズ枠８は、筒状部材である可動部材５の内側に配置され、可動部材５に取り付けられたマグネット４とフォーカスコイル９との間に磁気ギャップが形成されている。   A lens frame 8 is movably supported on the movable member 5. The lens frame 8 is a cylindrical member having a screw portion 8A to which a lens barrel (not shown) is attached, and a focus coil 9 is wound around a coil holding portion 8B provided on the outer periphery. The lens frame 8 is disposed inside the movable member 5 that is a cylindrical member, and a magnetic gap is formed between the magnet 4 attached to the movable member 5 and the focus coil 9.

レンズ枠８は、板バネ１０によって光軸方向（図示Ｚ方向）に沿って移動可能に支持されている。板バネ１０は、レンズ枠８の下端部８Ｃと可動部材５の下端部５Ｂとを弾性的に連結する下板バネ１１と、レンズ枠８の上端部８Ｄと可動部材５の上端部５Ｃとを弾性的に連結する上板バネ１２，１３を備えている。上板バネ１２，１３は、左右対称の２部材によって構成されている。 The lens frame 8 is supported by a leaf spring 10 so as to be movable along the optical axis direction (Z direction in the drawing). The leaf spring 10 includes a lower leaf spring 11 that elastically connects the lower end portion 8C of the lens frame 8 and the lower end portion 5B of the movable member 5, an upper end portion 8D of the lens frame 8, and an upper end portion 5C of the movable member 5. Upper leaf springs 12 and 13 that are elastically connected are provided. The upper leaf springs 12 and 13 are composed of two symmetrical members.

また、レンズ駆動装置１は、カバー部材１４を備えている。カバー部材１４は、図示省略したレンズに光を取り込む開口１４Ａを有しており、レンズ枠８と可動部材５を囲むように配置され、基端部１４Ｂがベース部材２の外周部に支持されている。   In addition, the lens driving device 1 includes a cover member 14. The cover member 14 has an opening 14 </ b> A that takes light into a lens (not shown), is disposed so as to surround the lens frame 8 and the movable member 5, and a base end portion 14 </ b> B is supported by the outer peripheral portion of the base member 2. Yes.

このようなレンズ駆動装置１において、ベース部材２には、配線部材２０が設けられている。配線部材２０は、例えば、リードフレームであり、樹脂製のベース部材２に一体成形（インサート成形）されている。配線部材２０の端部２０Ａは、ベース部材２の外周部に引き出されており、回路基板との接続端子になっている。配線部材２０は、リードフレームに限定されるものではなく、各種の配線構造を採用することができ、例えば、ＭＩＤ（Molded Interconnect Device, 成形回路部品）技術によって形成されたものなどであってもよい。   In such a lens driving device 1, the wiring member 20 is provided on the base member 2. The wiring member 20 is, for example, a lead frame, and is integrally formed (insert molding) on the resin base member 2. An end portion 20A of the wiring member 20 is drawn out to the outer peripheral portion of the base member 2, and serves as a connection terminal to the circuit board. The wiring member 20 is not limited to a lead frame, and various wiring structures can be employed. For example, the wiring member 20 may be formed by MID (Molded Interconnect Device) technology. .

この配線部材２０とコイル３とを接続するに際して、金属製のピン状部材２１を設けて、端子突起２０Ｐを形成しており、コイル３の引き出し線３Ａ，３Ｂを端子突起２０Ｐに巻き付け保持している。このような端子突起２０Ｐを設けることで、引き出し線３Ａ，３Ｂを配線部材２０に半田付けする際に、引き出し線３Ａ，３Ｂを端子突起２０Ｐに巻き付け保持した状態で半田付け作業を行うことができ、従来のように、ピンセットのような治具で引き出し線３Ａ，３Ｂを摘んで半田付けを行う場合と比較して、作業性を各段に向上させることができる。   When the wiring member 20 and the coil 3 are connected, a metal pin-like member 21 is provided to form the terminal protrusion 20P, and the lead wires 3A and 3B of the coil 3 are wound around the terminal protrusion 20P and held. Yes. By providing such terminal protrusions 20P, when the lead wires 3A and 3B are soldered to the wiring member 20, the soldering operation can be performed in a state where the lead lines 3A and 3B are wound and held around the terminal protrusion 20P. As compared with the conventional case where the lead wires 3A and 3B are pinched with a jig such as tweezers and soldered, the workability can be improved in each stage.

図２〜図４によって、更に具体例を説明する。一つのピン状部材２１（２１Ａ）は、ベース部材２に圧入されて、一つの配線部材２０に半田付けされて接続されており、ベース部材２の支持面２Ｂ側に突出するように配備され、他のピン状部材２１（２１Ｂ）は、同様に他の配線部材２０に接続されて、ベース部材２の裏面側に突出するように配備されている。このようなピン状部材２１（２１Ａ，２１Ｂ）は、配線部材（リードフレーム）２０と同様に、樹脂製のベース部材２に一体成形（インサート成形）することができる。なお、半田付けすること無しに、配線部材２０にピン状部材２１（２１Ａ，２１Ｂ）を圧入することで、ピン状部材２１（２１Ａ，２１Ｂ）と配線部材２０とを電気的に接続することもできる。   A specific example will be described with reference to FIGS. One pin-shaped member 21 (21A) is press-fitted into the base member 2, is soldered and connected to one wiring member 20, and is disposed so as to protrude toward the support surface 2B side of the base member 2. The other pin-shaped member 21 (21B) is similarly connected to the other wiring member 20, and is disposed so as to protrude to the back surface side of the base member 2. Similar to the wiring member (lead frame) 20, the pin-like member 21 (21A, 21B) can be integrally formed (insert molding) on the resin base member 2. In addition, the pin-shaped member 21 (21A, 21B) and the wiring member 20 may be electrically connected by press-fitting the pin-shaped member 21 (21A, 21B) into the wiring member 20 without soldering. it can.

そして、コイル３を配線部材２０に接続する際には、コイル３の外側の引き出し線３Ａを支持面２Ｂ側に突出しているピン状部材２１（２１Ａ）に巻き付け保持し、コイル３の内側の引き出し線３Ｂをベース部材３の裏面側に引き出して、この裏面側に突出しているピン状部材２１（２１Ｂ）に巻き付け保持する。その後は、ピン状部材２１（２１Ａ）と引き出し線３Ａ、ピン状部材２１（２１Ｂ）と引き出し線３Ｂを、それぞれ半田２２で覆うように半田付けすることで、接続作業を完了する。   When the coil 3 is connected to the wiring member 20, the lead wire 3 </ b> A outside the coil 3 is wound around the pin-like member 21 (21 </ b> A) protruding toward the support surface 2 </ b> B, and the lead inside the coil 3 is drawn out. The wire 3B is pulled out to the back surface side of the base member 3, and is wound and held on the pin-shaped member 21 (21B) protruding to the back surface side. Thereafter, the pin-like member 21 (21A) and the lead wire 3A, and the pin-like member 21 (21B) and the lead wire 3B are soldered so as to be covered with the solder 22, respectively, thereby completing the connection operation.

なお、この例では、配線部材（リードフレーム）とは別の部材であるピン状部材２１（２１Ａ，２１Ｂ）を用いて端子突起２０Ｐを形成したが、リードフレームを折り曲げ状にするなどして、リードフレームの一部として端子突起２０Ｐを形成してもよい。 In this example, the terminal protrusion 20P is formed by using the pin-shaped member 21 (21A, 21B) which is a member different from the wiring member (lead frame), but the lead frame is bent, etc. The terminal protrusion 20P may be formed as a part of the lead frame.

図５は、配線部材２０と端子突起２０Ｐの他の構成例を示している。この例では、ベース部材２自体に突起部２Ｐを形成し、配線部材２０と端子突起２０ＰをＭＩＤ技術によって形成している。この際、突起部２Ｐの全体に端子突起２０Ｐを形成しても良いし、突起部２Ｐの一部に端子突起２０Ｐを形成してもよい。実施例の突起部２Ｐの形状は四角柱であるが、他の実施形態では突起部２Ｐの形状が円柱など各種形状であってもよい。また、図示の例では、突起部２Ｐ自体に端子突起２０Ｐを形成しているが、最終的に半田によって配線部材２０と引き出し線３Ａ，３Ｂが電気的に接続されればよく、突起部２Ｐ自体に金属端子を形成しなくてもよい。   FIG. 5 shows another configuration example of the wiring member 20 and the terminal protrusion 20P. In this example, the protrusion 2P is formed on the base member 2 itself, and the wiring member 20 and the terminal protrusion 20P are formed by the MID technique. At this time, the terminal protrusion 20P may be formed on the entire protrusion 2P, or the terminal protrusion 20P may be formed on a part of the protrusion 2P. Although the shape of the protrusion 2P in the example is a quadrangular prism, in another embodiment, the shape of the protrusion 2P may be various shapes such as a cylinder. In the example shown in the figure, the terminal protrusion 20P is formed on the protrusion 2P itself. However, the wiring member 20 and the lead wires 3A and 3B may be finally electrically connected by solder, and the protrusion 2P itself. It is not necessary to form a metal terminal on the surface.

なお、 端子突起２０Ｐに巻きつけた引き出し線３Ａ,３Ｂを一時的に保持しやすくするように、端子突起２０Ｐの形状はＴ字型や、逆Ｌ字であってもよいし、端子突起２０Ｐの先端側が鉤状などであってもよい。また、端子突起２０Ｐの一部に粘着部材を取り付けることで、たとえば引き出し線３Ａ,３Ｂが半田付けされるまで、一時的に保持できるようにしてもよい。   Note that the shape of the terminal protrusion 20P may be a T-shape or an inverted L-shape so that the lead wires 3A and 3B wound around the terminal protrusion 20P can be temporarily held easily. The tip side may be hooked. Further, by attaching an adhesive member to a part of the terminal protrusion 20P, for example, the lead wires 3A and 3B may be temporarily held until they are soldered.

また、コイル３として自己融着線材を用いていて端子に巻きつけた後に、熱風等の加工を行うことで、引き出し線３Ａ，３Ｂのそれぞれが端子突起２０Ｐと融着するようにしてもよい。また、コイル３として自己融着線材を用いた場合、半田付けをするまでの形状保持のために、引き出し線３Ａ（３Ｂ）が自身の他部分と融着するようにしてもよい。この場合、引き出し線３Ａ，３Ｂのそれぞれは、端子突起２０Ｐと融着させなくてもよい。   Alternatively, the lead wire 3A, 3B may be fused to the terminal protrusion 20P by using a self-bonding wire as the coil 3 and winding it around the terminal, and then performing a process such as hot air. In addition, when a self-bonding wire is used as the coil 3, the lead wire 3A (3B) may be fused with the other part of itself in order to maintain the shape until soldering. In this case, each of the lead wires 3A and 3B may not be fused to the terminal protrusion 20P.

以上説明したように、本発明の実施形態に係るモバイル用電磁駆動装置（レンズ駆動装置１）は、コイル３の引き出し線３Ａ，３Ｂを突起に巻き付けた状態で半田付けをすることができるので、引き出し線３Ａ，３Ｂを治具で摘んで保持する必要が無く、狭いベース部材上のスペースでの作業であっても、良好な作業性を得ることができる。また、引き出し線３Ａ，３Ｂを巻き付けた状態で確実に半田付けすることができるので、接続不良を抑止することができ、歩留まりと品質の向上を図ることができる。   As described above, the mobile electromagnetic drive device (lens drive device 1) according to the embodiment of the present invention can be soldered in a state where the lead wires 3A and 3B of the coil 3 are wound around the protrusions. There is no need to pick and hold the lead wires 3A and 3B with a jig, and good workability can be obtained even when working in a space on a narrow base member. Further, since the lead wires 3A and 3B can be reliably soldered in a state in which the lead wires 3A and 3B are wound, connection failure can be suppressed, and yield and quality can be improved.

このような、モバイル用電磁駆動装置（レンズ駆動装置１）は、図６（ａ）に示すような小型の撮像装置１００に装備することができ、また、図６（ｂ）に示すような携帯電子機器（携帯情報端末）２００のカメラユニットなどに組み込むことができる。これらに組み込まれるモバイル用電磁駆動装置は、前述した配線接続の作業性改善、歩留まりと品質の向上により、高い生産性を得ることができると共に、高品質の撮像装置１００や携帯電子機器２００を低コストで製造することができる。 Such a mobile electromagnetic drive device (lens drive device 1) can be mounted on a small imaging device 100 as shown in FIG. 6A, and is also portable as shown in FIG. 6B. It can be incorporated into a camera unit of an electronic device (personal digital assistant) 200 or the like. The mobile electromagnetic drive device incorporated in these devices can obtain high productivity by improving the workability of wiring connection and improving the yield and quality described above, and can reduce the quality of the imaging device 100 and the portable electronic device 200. Can be manufactured at cost.

また、撮像装置１００だけに限らず、モバイル用電磁駆動装置は、ＶＣＭ（VCM：Voice Coil Motor）を用いる振動モータ（振動アクチュエータ）などが装備することができる。さらに、この振動モータは、携帯電子機器（携帯情報端末）２００のバイブレーションユニットに組み込むことができる。 In addition to the imaging device 100, the mobile electromagnetic drive device can be equipped with a vibration motor (vibration actuator) using a VCM (VCM: Voice Coil Motor). Furthermore, this vibration motor can be incorporated in the vibration unit of the portable electronic device (personal digital assistant) 200.
