【０００１】[0001]
本考案は、光ピックアップの防振支持構造に関するものである。 The present invention relates to a vibration isolation support structure for an optical pickup.

コンパクトディスク（ＣＤ），ＲＯＭ型コンパクトディスク（ＣＤ−ＲＯＭ） ，対話型コンパクトディスク（ＣＤ−Ｉ），ビデオディスク（ＶＤ）などの円盤 状の光ディスク（以下、ディスクと記す）は、音声情報，画像情報，文字情報な どの情報信号を複数の微小なピット列に変換して多量に収録していることは周知 である。 Disc-shaped optical discs (hereinafter referred to as discs) such as compact discs (CDs), ROM compact discs (CD-ROMs), interactive compact discs (CD-Is), and video discs (VDs) contain audio information and images. It is well known that information signals such as information and character information are converted into multiple minute pit rows and recorded in large quantities.
【０００３】 一般的に、上記ディスクはディスク駆動装置に適用されるものであり、このデ ィスクをディスク駆動装置内に設けたターンテーブルに装着し、この後ディスク を回転させ、光ピックアップをディスクの径方向に移動しながら音声情報，画像 情報，文字情報などの情報信号を読み取つている。 この際、光ピックアップは、微小なピット列に変換された情報信号を読み取るた め、光ピックアップに振動などの外乱が加わると読み取り性能に影響する場合も 考えられ、このためディスク駆動装置には防振対策が通常施されている。この防 振対策の例として、ディスク駆動装置の底板に防振用ゴム足を取り付けてディス ク駆動装置全体を防振したり、あるいは、ディスクの径方向に移動する光ピック アップ部分のみを防振ゴム，スプリングなどを用いて防振している。Generally, the above-mentioned disc is applied to a disc drive device, and the disc is mounted on a turntable provided in the disc drive device, and then the disc is rotated and an optical pickup is attached to the disc. While moving in the radial direction, it reads information signals such as voice information, image information, and character information. At this time, since the optical pickup reads the information signal converted into a minute pit train, it may be possible that the reading performance will be affected if a disturbance such as vibration is applied to the optical pickup. Shaking measures are usually taken. As an example of this anti-vibration measure, attach anti-vibration rubber feet to the bottom plate of the disc drive to isolate the entire disc drive, or to isolate only the optical pickup that moves in the radial direction of the disc. Vibration is prevented by using rubber and springs.
【０００４】[0004]
ところで、ディスク駆動装置に施される防振対策として、ディスク駆動装置全 体を防振用ゴム足を用いて防振した場合には、防振用ゴム足にディスク駆動装置 の全重量が加わるため、防振用ゴム足の形状が大きくなりコストが上昇すると共 に、重量バランスなどを十分に考慮する必要から防振用ゴム足の設計工数がかか るなどの問題がある。 一方、ディスクの径方向に移動する光ピックアップ部分のみを防振ゴム，スプリ ングなどを用いて防振した場合には、光ピックアップ部分の重量負荷が小さいた め軽負荷用の防振ゴム，スプリングなどを用いて防振できるものの、これらの防 振材には光ピックアップ部分の重量負荷が常に加わっているため、経時変化など が発生し易いなどのの問題がある。 By the way, as an anti-vibration measure applied to the disk drive, if the entire disk drive is anti-vibrated using anti-vibration rubber feet, the entire weight of the disk drive is added to the anti-vibration rubber feet. As the shape of the rubber feet for vibration damping increases and the cost rises, there is also a problem that the number of man-hours for designing the rubber feet for vibration damping is increased because it is necessary to fully consider the weight balance. On the other hand, when only the optical pickup part that moves in the radial direction of the disc is vibration-isolated by using anti-vibration rubber or springs, the weight load of the optical pickup part is small, so the anti-vibration rubber and spring for light loads are used. Although it is possible to perform vibration isolation by using, for example, since the weight load of the optical pickup part is constantly applied to these vibration isolation materials, there is a problem that it easily changes with time.

【００１３】 図１及び図２において、ディスク駆動機構部２０を保持した枠体２１には、第 １，第２支持部２１ｂ，２１ｃが外周に沿って複数か所形成されており、これら の第１，第２支持部２１ｂ，２１ｃは互いに位置をずらして重量バランスを考慮 しながら三角形状の点として配設されている。 このうち、第１支持部２１ｂは枠体２１の外周下方に突出形成されており、これ らの第１支持部２１ｂには防振ゴムなどの防振部材３１（以下、防振ゴム３１と も記す）がそれぞれ嵌め込まれている。尚、実施例では、防振部材３１として防 振ゴムを用いているが、これに限ることなく、防振用スプリングなどを用いても 良い。 一方、第２支持部２１ｃは、枠体２１の外周中間高さ位置に三角錐状のピボット として突出形成されており、後述する枠体支持部材４２〜４４に形成した係合部 （丸孔）４２ａ１〜４４ａ１が接離自在となっている。In FIGS. 1 and 2, a frame body 21 holding a disk drive mechanism section 20 is formed with a plurality of first and second support sections 21b and 21c along the outer periphery thereof. The first and second support portions 21b and 21c are arranged as triangular points by shifting their positions from each other while considering the weight balance. Of these, the first support portions 21b are formed so as to project below the outer periphery of the frame body 21, and the first support portions 21b have a vibration isolation member 31 such as a vibration isolation rubber (hereinafter also referred to as the vibration isolation rubber 31). Note) are fitted respectively. In the embodiment, the vibration-proof rubber is used as the vibration-proof member 31, but the invention is not limited to this, and a vibration-proof spring or the like may be used. On the other hand, the second supporting portion 21c is formed as a triangular pyramid-shaped pivot so as to project at an outer peripheral intermediate height position of the frame body 21, and is an engaging portion (round hole) formed in the frame body supporting members 42 to 44 described later. 42a 1 to 44a 1 are freely contactable and separable.
【００１４】 また、枠体２１の底面２１ｃの下方には、少し間隔を離して装置１０の基台と なるシャーシ３２が設けられている。 上記シャーシ３２上には、モータ３３と減速機構部３４を介して軸３５を中心に 回動するカムホィール３６が設けられ、このカムホィール３６に形成したカム溝 ３６ａに軸３７を中心として回動するカムレバー３８の一端部に固着したピン３ ８ａが添接し、且つ、軸３７を介した他端部に当接部３８ｂが形成されている。Further, below the bottom surface 21 c of the frame body 21, a chassis 32 that serves as a base of the apparatus 10 is provided at a slight distance. A cam wheel 36 that rotates about a shaft 35 is provided on the chassis 32 via a motor 33 and a reduction mechanism 34, and a cam lever 36 that rotates about a shaft 37 in a cam groove 36a formed in the cam wheel 36. A pin 38a fixed to one end of 38 is abutted, and an abutting part 38b is formed at the other end via the shaft 37.
【００１５】 更に、シャーシ３２上で枠体２１の底面２１ｄの下方には、カムレバー３８と 協働する摺動部材３９がシャーシ３２上を矢印Ｘ１，Ｘ２方向に摺動自在に設け られ、且つ、摺動部材３９と協働する枠体支持部材４２〜４４がシャーシ３２上 に回動支持されている。A sliding member 39 that cooperates with the cam lever 38 is provided on the chassis 32 below the bottom surface 21d of the frame body 21 so as to be slidable on the chassis 32 in the directions of arrows X 1 and X 2 . Further, frame support members 42 to 44 that cooperate with the sliding member 39 are rotatably supported on the chassis 32.
【００１６】 ここで、摺動部材３９及び枠体支持部材４２〜４４を図４に拡大して示して説 明すると、摺動部材３９には、シャーシ３２に固着したガイドピン４０，４０に 沿って案内されるガイド溝３９ｂ，３９ｂが形成されており、シャーシ３２と摺 動部材３９とに掛止した引張バネ４１により摺動部材３９が常に矢印Ｘ２方向に 付勢され、一端部から直角上方に突出形成した曲げ片３９ａがカムレバー３８の 当接部３８ｂに当接している。Here, when the sliding member 39 and the frame body supporting members 42 to 44 are shown in an enlarged manner in FIG. 4, the sliding member 39 is provided along the guide pins 40, 40 fixed to the chassis 32. guide grooves 39b which are guided Te, 39b are formed, the sliding member 39 is always biased in the direction of arrow X 2 by a tensile spring 41 hooked to the chassis 32 and the sliding member 39, a right angle from one end The bent piece 39a protruding upward is in contact with the contact portion 38b of the cam lever 38.
【００１７】 一方、シャーシ３２に固着した軸４５Ａ〜４５Ｃに回動支持された枠体支持部 材４２〜４４には、それぞれの一端部から直角上方に曲げ片４２ａ〜４４ａが突 出形成されており、この曲げ片４２ａ〜４４ａに係合部４２ａ１〜４４ａ１（以 下、丸孔４２ａ１〜４４ａ１とも記す）が形成されている。これらの丸孔４２ａ １ 〜４４ａ１には、後述するように枠体２１の第２支持部２１ｃに形成したピボ ットが接離するようになる。この際、とくに、第２支持部２１ｃに形成した三角 錐状のピボットと、曲げ片４２ａ〜４４ａに形成した丸孔４２ａ１〜４４ａ１と で係合関係を維持するようにしたため、両者が離れている状態から係合させた時 に挿入動作が確実となり、且つ、両者の位置決めも確実に行うことができる。尚 、実施例では、枠体２１側にピボットを形成し、枠体支持部材４２〜４４側に丸 孔４２ａ１〜４４ａ１を形成したが、両者を逆に形成しても良い。On the other hand, bending pieces 42a to 44a are formed at right angles upward from one end of each of the frame body supporting members 42 to 44 pivotally supported by the shafts 45A to 45C fixed to the chassis 32. And the engaging portions 42a on the bending pieces 42a to 44a.1~ 44a1(Hereinafter, round hole 42a1~ 44a1(Also noted) is formed. These round holes 42a 1 ~ 44a1The pivot formed on the second support portion 21c of the frame body 21 comes into contact with and separates from it. At this time, in particular, the triangular pyramid-shaped pivot formed on the second support portion 21c and the round hole 42a formed on the bending pieces 42a to 44a are formed.1~ 44a1Since the engagement relationship is maintained by and, when the two are engaged from the separated state, the insertion operation becomes reliable, and the positioning of the both can be surely performed. In the embodiment, the pivot is formed on the frame body 21 side, and the round holes 42a are formed on the frame body supporting members 42 to 44 side.1~ 44a1However, both may be formed in reverse.
【００１８】 更に、図示手前右側の枠体支持部材４２は、摺動部材３９の他端部に形成した 係合部３９ｃに中間部に形成した被係合部４２ｂが係合している。また、図示手 前左側の枠体支持部材４はが、枠体支持部材４２の他端部に形成した係合部４２ ｃに他端部に形成した被係合部４３ｂが係合している。また、図示奥方の枠体支 持部材４４は、摺動部材３９の中間部に形成した係合部３９ｄに中間部に形成し た被係合部４４ｂが係合している。上記のように、枠体支持部材４２〜４４を摺 動部材３９に係合させたため、枠体支持部材４２〜４４は摺動部材３９の移動と 協働して軸４５Ａ〜４５Ｃを中心にして回動できる構成となっている。Further, in the frame body supporting member 42 on the front right side in the drawing, an engaged portion 39c formed at the other end of the sliding member 39 is engaged with an engaged portion 42b formed at an intermediate portion. Further, in the frame body supporting member 4 on the left side in the drawing, the engaged portion 42c formed at the other end portion of the frame body supporting member 42 is engaged with the engaged portion 43b formed at the other end portion. . Further, in the frame body supporting member 44 at the back of the figure, an engaged portion 39d formed in the intermediate portion of the sliding member 39 is engaged with an engaged portion 44b formed in the intermediate portion. As described above, since the frame body supporting members 42 to 44 are engaged with the sliding member 39, the frame body supporting members 42 to 44 cooperate with the movement of the sliding member 39 and center around the shafts 45A to 45C. It is configured to be rotatable.
【００１９】 また、カムホィール３６のカム溝３６ａによって回動するカムレバー３８の当 接部３８ｂが、摺動部材３９の曲げ片３９ａを引張バネ４１に抗して矢印Ｘ１方 向に押圧すると、摺動部材３９と協働する枠体支持部材４２〜４４が、それぞれ の回動支点となる軸４５Ａ〜４５Ｃを中心にして矢印方向に回動するので、枠体 支持部材４２〜４４の曲げ片４２ａ〜４４ａも開拡する方向（矢印方向）に回動 するようになっている。Further, when the contact portion 38b of the cam lever 38 which is rotated by the cam groove 36a of the cam wheel 36 presses the bending piece 39a of the sliding member 39 against the tension spring 41 in the arrow X 1 direction, the sliding movement occurs. Since the frame body supporting members 42 to 44 that cooperate with the moving member 39 rotate in the directions of the arrows about the shafts 45A to 45C, which are the pivotal fulcrums, the bending pieces 42a of the frame body supporting members 42 to 44, respectively. The parts 44a to 44a also rotate in the direction of expansion (arrow direction).
【００２０】 ここで、摺動部材３９及び枠体支持部材４２〜４４の上方から、それぞれに形 成した曲げ片３９ａ，４２ａ〜４４ａを避けながら、ディスク駆動機構部２０を 保持した枠体２１を、図１に示したように複数の防振ゴム３１を介してシャーシ ３２上に支持させている。この際、防振ゴム３１は、前述したように枠体２１の 第１支持部２１ｂに固着されていると共に、防振ゴム３１の底面３１ａがシャー シ３２上に固着されている。Here, from above the sliding member 39 and the frame body supporting members 42 to 44, the frame body 21 holding the disk drive mechanism unit 20 is avoided while avoiding the bending pieces 39a and 42a to 44a formed respectively. As shown in FIG. 1, it is supported on the chassis 32 via a plurality of anti-vibration rubbers 31. At this time, the vibration-proof rubber 31 is fixed to the first support portion 21b of the frame body 21 as described above, and the bottom surface 31a of the vibration-proof rubber 31 is fixed to the chassis 32.
【００２１】 そして、図１に示した如く、カムホィール３６を動作して、カムレバー３８を 介して摺動部材３９を矢印Ｘ１に移動すると、枠体支持部材４２〜４４の曲げ片 ４２ａ〜４４ａが開拡する方向に回動し、曲げ片４２ａ〜４４ａに形成した丸孔 （係合部）４２ａ１〜４４ａ１が、枠体２１の第２支持部２１ｃに形成したピボ ットから離間するので、ディスク駆動機構部２０を保持した枠体２１が、防振ゴ ム３１のみによってシャーシ３２に支持された状態となる。従って、ディスク駆 動機構部２０は防振ゴム３１によりシャーシ３２からフローティングされた状態 となるので、この時、ターンテーブル２３にチャッキングしたディスク１を、光 ピックアップ２６により再生（又は記録）すれば、防振ゴム３１のフローティン グ作用により、光ピックアップ２６の動作時には振動などの外乱が加わりにくく なる。Then, as shown in FIG. 1, when the cam wheel 36 is operated to move the sliding member 39 to the arrow X 1 via the cam lever 38, the bending pieces 42a to 44a of the frame body supporting members 42 to 44 are moved. Since the circular holes (engaging portions) 42a 1 to 44a 1 formed in the bending pieces 42a to 44a are rotated in the expanding direction and are separated from the pivot formed in the second supporting portion 21c of the frame body 21. The frame 21 holding the disk drive mechanism 20 is supported by the chassis 32 only by the vibration isolating gum 31. Therefore, the disk drive mechanism 20 is floated from the chassis 32 by the anti-vibration rubber 31. At this time, if the disk 1 chucked on the turntable 23 is reproduced (or recorded) by the optical pickup 26. Due to the floating action of the anti-vibration rubber 31, disturbance such as vibration is less likely to be applied when the optical pickup 26 operates.
【００２２】 一方、図２に示した如く、カムホィール３６を前記とは逆方向に動作して、カ ムレバー３８を介して摺動部材３９を矢印Ｘ２に移動すると、枠体支持部材４２ 〜４４の曲げ片４２ａ〜４４ａが閉じる方向に回動し、曲げ片４２ａ〜４４ａに 形成した丸孔（係合部）４２ａ１〜４４ａ１が、枠体２１の第２支持部２１ｃに 形成したピボットに入り込むので、ディスク駆動機構部２０を保持した枠体２１ が枠体支持部材４２〜４４に支持され、これにより枠体２１が防振ゴム３１に支 持されることなくシャーシ３２にしっかり支持された状態となる。この時、光ピ ックアップ２６を非動作にしておけば、防振ゴム３１にディスク駆動機構部２０ の重量が負荷されないので、防振ゴム３１の変形が軽減されると共に、経時変化 も起こりにくくなる。On the other hand, as shown in FIG. 2, when the cam wheel 36 is operated in the opposite direction to move the sliding member 39 to the arrow X 2 through the cam lever 38, the frame body supporting members 42 to 44 are moved. bending piece 42A～44a closing rotates in the direction of the bending piece round hole (engaging portion) formed in 42a~44a 42a 1 ~44a 1 is a pivot formed on the second supporting portion 21c of the frame 21 Since it enters, the frame body 21 holding the disk drive mechanism section 20 is supported by the frame body supporting members 42 to 44, whereby the frame body 21 is firmly supported by the chassis 32 without being supported by the vibration isolating rubber 31. It becomes a state. At this time, if the optical pickup 26 is not operated, the vibration damping rubber 31 is not loaded with the weight of the disk drive mechanism 20, so that the deformation of the vibration damping rubber 31 is reduced and the secular change is less likely to occur. .
【００２３】 以上のように構成した防振支持機構部３０では、枠体支持部材４２〜４４の丸 孔（係合部）４２ａ１〜４４ａ１を枠体２１の第２支持部２１ｃに接離する駆動 源としてカムホィール３６を用い、連結部材としてカムレバー３８，摺動部材３ ９を用いているが、これに限ることなく、例えば周知のソレノイドなどを用いて 上記と同様な動作をさせても良い。In the vibration-damping support mechanism portion 30 configured as described above, the round holes (engaging portions) 42 a 1 to 44 a 1 of the frame body supporting members 42 to 44 are brought into contact with and separated from the second support portion 21 c of the frame body 21. Although the cam wheel 36 is used as a driving source and the cam lever 38 and the sliding member 39 are used as connecting members, the present invention is not limited to this, and a known solenoid or the like may be used to perform the same operation as described above. .
【００２４】[0024]
以上詳述した本考案に係わる光ピックアップの防振支持構造によると、請求項 １記載において、光ピックアップの動作時、複数の枠体支持部材の係合部を枠体 の複数の第２支持部から離間して枠体を複数の防振部材により防振しているので 、光ピックアップに振動などの外乱が加わりにくくなる利点がある。 一方、光ピックアップの非動作時、複数の枠体支持部材の係合部を枠体の複数の 第２支持部に係合させているので、枠体がシャーシにしっかり支持されることに なり、防振部材（防振ゴム）にディスク駆動機構部の重量が負荷されないので、 防振部材の変形が軽減されると共に、経時変化も起こりにくくなる利点がある。 According to the vibration isolating support structure for an optical pickup according to the present invention, which has been described in detail above, according to claim 1, when the optical pickup is in operation, the engaging portions of the plurality of frame body supporting members are replaced with the plurality of second supporting portions of the frame body. Since the frame body is isolated from the frame body by a plurality of vibration isolation members, there is an advantage that a disturbance such as vibration is less likely to be applied to the optical pickup. On the other hand, when the optical pickup is not operating, the engaging portions of the plurality of frame supporting members are engaged with the plurality of second supporting portions of the frame, so that the frame is firmly supported by the chassis. Since the weight of the disk drive mechanism is not loaded on the vibration-proof member (vibration-proof rubber), there is an advantage that the deformation of the vibration-proof member is reduced and the change over time is less likely to occur.
【００２５】 更に、請求項２記載において、とくに、枠体支持部材の係合部と、枠体の第２ 支持部との係合関係を三角錐状のピボットと、丸孔とで係合関係を維持するよう にしたため、両者が離れている状態から係合させた時に挿入動作が確実となり、 且つ、両者の位置決めも確実に行うことができる。Further, in claim 2, the engagement relationship between the engagement portion of the frame body supporting member and the second support portion of the frame body is particularly the engagement relationship between the triangular pyramid-shaped pivot and the round hole. Therefore, the insertion operation becomes reliable when the two are engaged from the separated state, and the positioning of the both can be surely performed.
