Description

【0001】
【発明が属する技術分野】
本発明は、光学ピックアップを再生基板にガイド軸で支持した光学ピックアップのガイド装置に関する。
【0002】
【従来の技術】
ディスクプレーヤにおける光学ピックアップは、一般に再生基板に平行に配置された一対のガイドにより移動自在に支持される。このガイドは、光学ピックアップをディスクの面に対して平行で、かつ円滑に移動させることが求められる。このガイドの一方には、例えば直径が3ミリ、長さが80ミリ程度のステンレス製のガイド軸が使用される。このようなガイド軸の再生基板への取付は、従来、特開2000-149466号公報に示されるように、固定金具や皿ねじを用いて再生基板に取付られていた。固定金具は、再生基板にねじ止めされることで、ガイド軸を再生基板に固定し、皿ねじは再生基板にねじ止めされることで、頭部のテーパ面がガイド軸を再生基板の表面とガイド軸を軸方向とに押付けるようにして、ガイド軸を再生基板に固定している。
【0003】
【発明が解決しようとする課題】
光学ピックアップを再生基板に取付けるときは、光学ピックアップの軸孔にガイド軸を挿通させた状態で、ガイド軸の両端を再生基板に固定する。ところが光学ピックアップは、高精度に組立てられた精密部品であるから再生基板へ取付けるときは無振動で行いたい。しかし、上記の公報に示されるように、ねじによるガイド軸の取付けでは、エアードライバーや電動式ドライバー等の動力螺子締め工具を使用すると、ねじ締め付け時の振動が、再生基板やガイド軸を介して光学ピックアップに伝わるので好ましくない。一方、動力螺子締め工具を使用しないと、ガイド軸を再生基板に取付けるのに時間がかかり、生産性が悪くなる。
本発明は、光学プックアップを無振動で素早く再生基板に取付けることができる光学ピックアップのガイド装置を提供する。
【0004】
【課題を解決するための手段】
本発明の光学ピックアップのガイド装置は、再生基板にガイド軸の一端側で外周に接する第一当接部と、ガイド軸の他端側でガイド軸の外周に接する第二当接部とを設ける。そして、ガイド軸の一端縁に当接して、ガイド軸を軸方向と第一当接部と再生基板の表面とに押し付ける弾性部材を再生基板に取付けた。さらに再生基板には、この弾性部材によるガイド軸の軸方向の付勢力を受けてガイド軸を第二当接部と再生基板の表面とに押付ける受け部を設けた。
【0005】
光学ピックアップは、ガイド軸に支持された状態でガイド軸が再生基板の第一及び第二当接部に掛け止めされた後に、弾性部材が再生基板に取付けられると、弾性部材の弾力でガイド軸と共に再生基板に取付られる。ガイド軸は、弾性部材の弾力で再生基板に固定されるので、光学ピックアップは、無振動で素早く再生基板に取付けられる。第一及び第二当接部を再生基板に一体的に形成すると、光学ピックアップのガイド装置を簡素化できる。また、第一当接部にガイド軸が再生基板から浮き上がることを阻止するストッパを形成すると、ガイド軸を再生基板に取付ける際に仮止めできるのでいっそう生産性がよくなる。
【0006】
さらに、上記弾性部材を、コイル部を有する棒ばねとして、そのコイル部を再生基板に取付けると共に、ガイド軸を押圧する棒ばねの終端を再生基板の裏面側にて屈曲させて形成した。そして、棒ばねの終端を再生基板の裏面側に位置させることで、ガイド軸を押圧する部位がガイド軸の端縁からの外れることを防止した。
【0007】
【実施例】
本発明の光学ピックアップのガイド装置を図1から図5に亘って説明する。図1において光学ピックアップ1には、片側にガイド軸2に嵌合する軸孔3と、他側に再生基板4に取付けられるガイド板5に嵌合する凹溝6とが形成されている。そして、光学ピックアップ1は、軸孔3に挿通されるガイド軸2と、凹溝6に嵌りこむガイド板5とで再生基板4に移動自在に支持される。再生基板4には、光学ピックアップ1の移動範囲全域に亘って光学ピックアップ1を収容する大きさの取付け孔7が設けられ、この取付孔7の一方の縁にガイド板5、他方の縁にガイド軸2が平行に並べて取付けられる。光学ピクアップ1の片側を支持するガイド軸2は、断面円形のステンレス製で外径を軸孔に高精度に嵌合するよう研摩加工されている。一方、ガイド板5は合成樹脂製の板で、凹溝6に少ない遊びで嵌る厚みに成形されている。
【0008】
再生基板4の前記取付け孔7の縁には、ガイド板5を取付けた側と対向する側にガイド軸2を固定支持する第一当接部8と第二当接部9とを折り曲げ形成している。これら第一及び第二当接部8,9は、ガイド軸の中心線10に対し光学ピックアップ1側に位置し、各当接部は、ガイド軸の外周を当接させることでガイド軸2が光学ピックアップ1側に移動することを阻止している。そして、第一当接部8は逆L字形に形成され、先端部を、ガイド軸が再生基板4から浮き上がることを阻止するストッパ11としている。
【0009】
再生基板4の第一当接部8の近傍には、ガイド軸2を再生基板4に固定するねじりコイルばね12(弾性部材)の取付部13が設けられる。このばね12は、コイル部12aの両端に腕12b,12cを延出させた形状をなす。また、取付部13は、ばね12のコイル部12aに挿通する支持片14と、コイル部12から突出する一方の腕12bを掛け止めするばね受け片15とで構成される。支持片14は、コイル部12aが支持片14に装着されて一方の腕12bがばね受け片15に掛け止めされたとき、他方の腕12cの中間部分がガイド軸の中心線10に対し、約45度の角度でガイド軸2の一端縁2aに当接する位置に設定されている。また、再生基板4には、他方の腕12cの終端を挿通させる長孔4aが設けられている。
【0010】
ばね12の他方の腕12cは図2に示すように、終端を再生基板4の長孔4aを相通させて終端部分12dを再生基板4の下面側に位置するようクランク状に折り曲げ形成されている。この終端部分12dは、他方の腕12cの中間部分がガイド軸2の一端縁2aを押圧したとき、その反力で他方の腕12cが再生基板4から浮上がることを禁止する。そこで他方の腕12cは、再生基板4から浮き上がることなくガイド軸2を再生基板4の表面4cに強力に押し付けることができる。
【0011】
再生基板4の外縁を折り曲げた側壁4bには、角孔16が開けられ、この角孔16の上縁をガイド軸2の他端縁2bに当接する受け部17としている。この受け部17は、図3に示すように、再生基板4の面からの高さがガイド軸2の直径より僅かに低く位置付けられ、ガイド軸2の中心線10に対して第二当接部9の反対側の位置でガイド軸2の他端縁2bを当接させている。
【0012】
この角孔16を開けた壁部4bは、図4に示すようにガイド軸2の中心線10に対し、平面図上において約45度の傾斜を与えられており、ばね12による軸方向の付勢力を受けてガイド軸2の外周を第二当接部9および再生基板4の表面4cに押し付ける。
【0013】
ガイド軸2を再生基板4に固定するには、光学ピックアップ1の軸孔にガイド軸2を挿通させた状態で凹溝6をガイド板5に嵌め込む。そして、ガイド軸2の他端縁2bを角孔16の上縁に当接させる。そして、再生基板4の長孔4aにばね12の終端部分12dを差込み、コイル部12aを支持片14に装着する。そして、ばね12の一方の腕12bを弾力変位させながら受け片15に掛け止めすると、他方の腕12cの中間部分がガイド軸2の一端縁2aに当接してガイド軸2の外周を第一当接部及び再生基板4の表面に中心線10に対し約45度の方向から押付けて、ガイド軸2の取付が完了する。
【0014】
このときのばね12の弾性力F1は、図5に示すようにガイド軸2の中心線10と平行な分力F2と、中心線10に直角な分力F3とに分圧される。そして、分力F2は、ガイド軸2の他端縁2bが角孔16の受け部17に当接する位置で、壁4bと平行な方向の分力F4と、壁と垂直な方向の分力F5とに分圧される。分力F5は、ガイド軸2を第二当接部9に押付けるように作用し、この分力F5は、他端縁2bが受け部17に当接させることで図3に示すように分力F6を発生させる。この分力F6は、ガイド軸2の他端側を再生基板4の表面4cに押付ける。一方、分力F3は、ガイド軸2を第一当接部8に向けて押付けるとともに、図2に示すようにガイド軸2の一端側を再生基板4の表面4cに押付ける方向の分力F7を生じさせる。
【0015】
ガイド軸2は、第一及び第二当接部8,9と受け部とに掛け止めした後に、ばね12を再生基板4に取付けるだけで、再生基板4に固定される。したがって、光学プックアップ1を無振動で素早く再生基板4に取付けることできる。 本実施例では第一及び第二当接部9を再生基板4に一体に形成したが、これらは再生基板4とは別体としても良い。また、ばね12による分力F7が充分に大きく取れれば、第一当接部8のストッパ11は必ずしも設る必要がない。
【0016】
【発明の効果】
以上のように本発明の光学ピックアップのガイド装置によれば、ガイド軸2は、弾性部材の弾力で再生基板4に固定されるので、光学ピックアップ1は、無振動で素早く再生基板4に取付けられる。この第一及び第二当接部9を再生基板4に一体的に形成すると、光学ピックアップ1のガイド装置を簡素化できる。また、第一当接部8にガイド軸2が再生基板4から浮き上がることを阻止するストッパ11を形成すると、ガイド軸2を再生基板4に取付ける際に仮止めできるのでいっそう生産性がよくなる。

[Technical field to which the invention belongs]
The present invention relates to a guide device for an optical pickup in which an optical pickup is supported on a reproduction substrate by a guide shaft.
[0002]
[Prior art]
In general, an optical pickup in a disc player is movably supported by a pair of guides arranged in parallel to a reproduction substrate. This guide is required to move the optical pickup smoothly and parallel to the disk surface. For example, a stainless steel guide shaft having a diameter of about 3 mm and a length of about 80 mm is used for one of the guides. Conventionally, the guide shaft is attached to the reproduction substrate using a fixture or a countersunk screw as disclosed in Japanese Patent Application Laid-Open No. 2000-149466. The fixing bracket is screwed to the reproduction board to fix the guide shaft to the reproduction board, and the countersunk screw is screwed to the reproduction board so that the taper surface of the head is connected to the surface of the reproduction board. The guide shaft is fixed to the reproduction substrate by pressing the guide shaft in the axial direction.
[0003]
[Problems to be solved by the invention]
When the optical pickup is attached to the reproduction substrate, both ends of the guide shaft are fixed to the reproduction substrate with the guide shaft inserted through the shaft hole of the optical pickup. However, since an optical pickup is a precision part assembled with high precision, it is desired to perform vibration-free operation when attaching the optical pickup to a reproduction substrate. However, as shown in the above publication, when mounting a guide shaft with screws, if a power screw tightening tool such as an air screwdriver or an electric screwdriver is used, vibration during screw tightening is caused via the reproduction substrate or the guide shaft. Since it is transmitted to the optical pickup, it is not preferable. On the other hand, if a power screw fastening tool is not used, it takes time to attach the guide shaft to the reproduction substrate, resulting in poor productivity.
The present invention provides a guide device for an optical pickup capable of quickly attaching an optical poke-up to a reproduction substrate without vibration.
[0004]
[Means for Solving the Problems]
The guide device of the optical pickup of the present invention includes a first contact portion that contacts the outer periphery on one end side of the guide shaft and a second contact portion that contacts the outer periphery of the guide shaft on the other end side of the guide shaft. . Then, an elastic member that is in contact with one end edge of the guide shaft and presses the guide shaft against the axial direction, the first contact portion, and the surface of the reproduction substrate is attached to the reproduction substrate. Further, the reproduction substrate is provided with a receiving portion that receives the urging force of the guide shaft in the axial direction by the elastic member and presses the guide shaft against the second contact portion and the surface of the reproduction substrate.
[0005]
When the elastic member is attached to the reproduction substrate after the guide shaft is hooked on the first and second abutting portions of the reproduction substrate while being supported by the guide shaft, the optical pickup picks up the guide shaft by the elasticity of the elastic member. At the same time, it is attached to the reproduction substrate. Since the guide shaft is fixed to the reproduction substrate by the elasticity of the elastic member, the optical pickup can be quickly attached to the reproduction substrate without vibration. If the first and second contact portions are formed integrally with the reproduction substrate, the guide device for the optical pickup can be simplified. Further, if a stopper for preventing the guide shaft from floating from the reproduction substrate is formed at the first contact portion, the guide shaft can be temporarily fixed when attached to the reproduction substrate, so that the productivity is further improved.
[0006]
Further, the elastic member is formed as a bar spring having a coil part, and the coil part is attached to the reproduction board, and the end of the bar spring pressing the guide shaft is bent on the back side of the reproduction board. Then, by positioning the end of the bar spring on the back surface side of the reproduction substrate, the portion that presses the guide shaft is prevented from coming off from the end edge of the guide shaft.
[0007]
【Example】
An optical pickup guide apparatus according to the present invention will be described with reference to FIGS. In FIG. 1, the optical pickup 1 is formed with a shaft hole 3 fitted to the guide shaft 2 on one side and a concave groove 6 fitted to a guide plate 5 attached to the reproduction substrate 4 on the other side. The optical pickup 1 is movably supported on the reproduction substrate 4 by a guide shaft 2 inserted through the shaft hole 3 and a guide plate 5 fitted in the groove 6. The reproduction substrate 4 is provided with a mounting hole 7 sized to accommodate the optical pickup 1 over the entire movement range of the optical pickup 1, and a guide plate 5 is provided at one edge of the mounting hole 7 and a guide is provided at the other edge. Axis 2 is mounted side by side in parallel. The guide shaft 2 that supports one side of the optical pickup 1 is made of stainless steel having a circular cross section, and is polished so that the outer diameter can be fitted into the shaft hole with high accuracy. On the other hand, the guide plate 5 is a plate made of synthetic resin, and is formed to a thickness that fits in the groove 6 with little play.
[0008]
A first abutting portion 8 and a second abutting portion 9 for fixing and supporting the guide shaft 2 are formed at the edge of the mounting hole 7 of the reproduction substrate 4 on the side facing the side where the guide plate 5 is mounted. ing. These first and second abutting portions 8 and 9 are located on the optical pickup 1 side with respect to the center line 10 of the guide shaft, and each abutting portion abuts the outer periphery of the guide shaft so that the guide shaft 2 The movement to the optical pickup 1 side is prevented. The first abutting portion 8 is formed in an inverted L shape, and the tip portion serves as a stopper 11 that prevents the guide shaft from floating from the reproduction substrate 4.
[0009]
In the vicinity of the first contact portion 8 of the reproduction substrate 4, an attachment portion 13 of a torsion coil spring 12 (elastic member) that fixes the guide shaft 2 to the reproduction substrate 4 is provided. The spring 12 has a shape in which arms 12b and 12c are extended at both ends of the coil portion 12a. The attachment portion 13 includes a support piece 14 that is inserted into the coil portion 12a of the spring 12 and a spring receiving piece 15 that latches one arm 12b protruding from the coil portion 12. When the coil portion 12a is mounted on the support piece 14 and one arm 12b is hooked on the spring receiving piece 15, the support piece 14 has an intermediate portion of the other arm 12c with respect to the center line 10 of the guide shaft. It is set at a position where it abuts on one end edge 2a of the guide shaft 2 at an angle of 45 degrees. Further, the reproduction substrate 4 is provided with a long hole 4a through which the end of the other arm 12c is inserted.
[0010]
As shown in FIG. 2, the other arm 12c of the spring 12 is bent and formed in a crank shape so that the end portion 12d is located on the lower surface side of the reproduction substrate 4 with the long hole 4a of the reproduction substrate 4 passing through. . This end portion 12d inhibits the other arm 12c from floating from the reproduction substrate 4 by the reaction force when the intermediate portion of the other arm 12c presses the one end edge 2a of the guide shaft 2. Therefore, the other arm 12 c can strongly press the guide shaft 2 against the surface 4 c of the reproduction substrate 4 without lifting from the reproduction substrate 4.
[0011]
A square hole 16 is formed in the side wall 4b where the outer edge of the reproduction substrate 4 is bent, and the upper edge of the square hole 16 serves as a receiving portion 17 that abuts against the other end edge 2b of the guide shaft 2. As shown in FIG. 3, the receiving portion 17 is positioned so that the height from the surface of the reproduction substrate 4 is slightly lower than the diameter of the guide shaft 2, and the second abutting portion with respect to the center line 10 of the guide shaft 2. The other end 2b of the guide shaft 2 is brought into contact with the position 9 on the opposite side.
[0012]
As shown in FIG. 4, the wall portion 4 b in which the square hole 16 is opened is inclined by about 45 degrees on the plan view with respect to the center line 10 of the guide shaft 2. Under the force, the outer periphery of the guide shaft 2 is pressed against the second contact portion 9 and the surface 4c of the reproduction substrate 4.
[0013]
In order to fix the guide shaft 2 to the reproduction substrate 4, the groove 6 is fitted into the guide plate 5 with the guide shaft 2 inserted through the shaft hole of the optical pickup 1. Then, the other end 2 b of the guide shaft 2 is brought into contact with the upper edge of the square hole 16. Then, the terminal end portion 12 d of the spring 12 is inserted into the elongated hole 4 a of the reproduction substrate 4, and the coil portion 12 a is attached to the support piece 14. Then, when one arm 12b of the spring 12 is elastically displaced and hooked to the receiving piece 15, the intermediate portion of the other arm 12c abuts against one end edge 2a of the guide shaft 2, and the outer periphery of the guide shaft 2 is first applied. By pressing the contact portion and the surface of the reproduction substrate 4 from the direction of about 45 degrees with respect to the center line 10, the mounting of the guide shaft 2 is completed.
[0014]
The elastic force F1 of the spring 12 at this time is divided into a component force F2 parallel to the center line 10 of the guide shaft 2 and a component force F3 perpendicular to the center line 10 as shown in FIG. The component force F2 includes a component force F4 in a direction parallel to the wall 4b and a component force F5 in a direction perpendicular to the wall at the position where the other end 2b of the guide shaft 2 contacts the receiving portion 17 of the square hole 16. The pressure is divided. The component force F5 acts to press the guide shaft 2 against the second abutting portion 9, and this component force F5 is divided as shown in FIG. Force F6 is generated. This component force F6 presses the other end side of the guide shaft 2 against the surface 4c of the reproduction substrate 4. On the other hand, the component force F3 pushes the guide shaft 2 toward the first abutting portion 8 and also exerts a component force in the direction of pushing one end of the guide shaft 2 against the surface 4c of the reproduction substrate 4 as shown in FIG. Gives rise to F7.
[0015]
The guide shaft 2 is fixed to the reproduction substrate 4 only by attaching the spring 12 to the reproduction substrate 4 after being hooked on the first and second contact portions 8 and 9 and the receiving portion. Therefore, the optical pokeup 1 can be quickly attached to the reproduction substrate 4 without vibration. In the present embodiment, the first and second contact portions 9 are formed integrally with the reproduction substrate 4, but these may be separated from the reproduction substrate 4. Further, if the component force F7 by the spring 12 is sufficiently large, the stopper 11 of the first contact portion 8 is not necessarily provided.
[0016]
【The invention's effect】
As described above, according to the guide device for the optical pickup of the present invention, the guide shaft 2 is fixed to the reproduction substrate 4 by the elasticity of the elastic member, so that the optical pickup 1 can be quickly attached to the reproduction substrate 4 without vibration. . If the first and second contact portions 9 are formed integrally with the reproduction substrate 4, the guide device for the optical pickup 1 can be simplified. Further, if the stopper 11 for preventing the guide shaft 2 from floating from the reproduction substrate 4 is formed on the first contact portion 8, the guide shaft 2 can be temporarily fixed when the guide shaft 2 is attached to the reproduction substrate 4, so that the productivity is further improved.
