Description

【０００１】
【発明の属する技術分野】
本発明は、コンピュータ等の電子機器に搭載され、ＣＤやＤＶＤといった光ディスクなどの再生、記録を行う薄型のディスク装置に関するものであり、特にディスク装置のトレイのロック構造に関するものである。
【０００２】
【従来の技術】
図６は従来のディスク装置のトレイ収納状態を示す斜視透視図、図７は同ディスク装置のトレイ排出状態を示す外観図である。ハウジング１はディスク装置の外装部を構成するものであり、コンピュータ等の電子機器に搭載される場合の、電子機器本体とディスク装置との接続部となる。ディスク装置の使用時には、図６に示すように、トレイ２がハウジング１の内部に収納されている。図７に示すように、トレイ排出状態では、ハウジング１内に設けられトレイ２を保持するレール４上を、トレイ２が前後に摺動することにより排出状態となり、ディスク３が着脱可能に配置される。
【０００３】
図８（ａ）および（ｂ）は同従来のディスク装置のトレイ収納状態を示す平面図および斜視透視図である。これらの図に示すように、ハウジング１内の奥部には、トレイ２がハウジング１内に収納された際にその一端５ａが当接して変位し、トレイ２をハウジング１から排出する方向に付勢するトレイ排出付勢部材５が配設されている。また、トレイ２における手前部分寄りの箇所には、軸６ａを中心に回動可能な係合部６が設けられており、この係合部６の先端の爪部６ｂは、ハウジング１に固定された状態で設けられた被係合部７に係脱自在とされている。また、係合部６は、トレイ２側に設けられている駆動部８（簡略的に示している）により回動され、トレイ収納状態では、駆動部８により係合部６を被係合部７に係合する姿勢に保持しており、これによりトレイ２が排出されることを規制している。
【０００４】
図９（ａ）および（ｂ）は同従来のディスク装置のトレイ排出中状態を示す平面図および斜視透視図である。これらの図に示すように、トレイ排出中の状態では、駆動部８により係合部６がａ方向に回動され、係合部６と被係合部７との係合が解除されている。これによりトレイ２の排出方向への移動の規制が解除され、トレイ排出付勢部材５の付勢力により、トレイ２が手前側に押し出されて排出される。
【０００５】
このように、従来のディスク装置では、トレイ収納時には、駆動部８により回動される係合部６を、ハウジング１に固定された被係合部７に係合させることで、ハウジング１からのトレイ２の排出を規制し、トレイ排出時には、駆動部８により回動される係合部６を、ハウジング１に固定された被係合部７から離脱させることで、ハウジング１からのトレイ２の排出を許容していた。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記従来のディスク装置の構成によれば、このディスク装置がコンピュータ等の電子機器に搭載された状態で、この電子機器の落下による衝撃などにより、トレイ２に対して排出方向に瞬間的に大きな加速度がかかったときに、前記加速度による大きな力が係合部６と被係合部７との係合箇所に作用して、互いに係合している係合部６や被係合部７が破損することがあった。
【０００７】
本発明は前記課題を解決するもので、通常のトレイ収納状態では係合部と被係合部とが良好に係合してトレイを収納姿勢に良好に保持できながら、電子機器の落下による衝撃などにより、トレイに対して排出方向に瞬間的に大きな加速度がかかったときでも係合部や被係合部が破損することを防止できるディスク装置を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
前記課題を解決するために、本発明は、ディスク装着部を有するトレイと、前記トレイを出退自在に保持するレールを介して前記トレイを収納するハウジングと、前記トレイが前記ハウジング内に引き込まれたトレイ収納状態において前記トレイを排出方向に付勢するトレイ排出付勢部材と、前記トレイに設けられた係合部と、前記ハウジングに設けられて前記係合部と係合する被係合部と、前記トレイ収納状態には前記係合部を、前記係合部と前記被係合部とが互いに係合する第１の姿勢に移動させ、前記トレイ排出時には前記係合部と前記被係合部とが互いに離反する第２の姿勢に移動させて前記トレイの排出を許容させる駆動部とを備えたディスク装置であって、前記被係合部がバネ部材を用いて構成され、前記バネ部材が、前記トレイ排出付勢部材の付勢方向と逆方向に、前記トレイ排出付勢部材の付勢力以上の与圧をもって設けられ、前記係合部と前記被係合部とが前記第１の姿勢にある状態で、前記トレイを強制的に排出方向に移動させる外力が作用した際に、前記被係合部が前記バネ部材の弾性変形域内で変位する構成としたことを特徴とする。
【０００９】
本発明によれば、通常のトレイ収納状態では係合部と被係合部とが良好に係合してトレイを収納姿勢に良好に保持できながら、コンピュータ等の電子機器に搭載された状態で、コンピュータ等電子機器の落下等により、トレイに排出方向に大きな加速度がかかったときでも係合部、被係合部が破損することのないディスク装置を提供できる。
【００１０】
【発明の実施の形態】
請求項１に記載の発明は、ディスク装着部を有するトレイと、前記トレイを出退自在に保持するレールを介して前記トレイを収納するハウジングと、前記トレイが前記ハウジング内に引き込まれたトレイ収納状態において前記トレイを排出方向に付勢するトレイ排出付勢部材と、前記トレイに設けられた係合部と、前記ハウジングに設けられて前記係合部と係合する被係合部と、前記トレイ収納状態には前記係合部を、前記係合部と前記被係合部とが互いに係合する第１の姿勢に移動させ、前記トレイ排出時には前記係合部と前記被係合部とが互いに離反する第２の姿勢に移動させて前記トレイの排出を許容させる駆動部とを備えたディスク装置であって、前記被係合部がバネ部材を用いて構成され、前記バネ部材が、前記トレイ排出付勢部材の付勢方向と逆方向に、前記トレイ排出付勢部材の付勢力以上の与圧をもって設けられ、前記係合部と前記被係合部とが前記第１の姿勢にある状態で、前記トレイを強制的に排出方向に移動させる外力が作用した際に、前記被係合部が前記バネ部材の弾性変形域内で変位する構成としたことを特徴としたものであり、トレイに排出方向に大きな加速度がかかったときには、係合部がバネ部材の弾性で変形することにより、係合部または被係合部が破損しないという作用を有する。
【００１１】
また、トレイ収納状態においては、バネ部材の与圧がトレイ排出付勢部材の付勢力以上であるため、ハウジングに対してのトレイ位置が収納位置に安定して保持されるという作用を有する。
【００１２】
請求項２に記載の発明は、請求項１に記載のディスク装置において、前記トレイを強制的に排出方向に移動させる所定値以上の外力が作用した際に、前記バネ部材の変位により前記係合部と前記被係合部との係合が解除されることを特徴とするものであり、上記所定値以上の外力が作用した場合に、係合部と被係合部との係合が解除されるので、バネ部材の変形や、係合部や被係合部の破損を防ぐという作用を有する。
【００１４】
（実施の形態）
以下に、本発明の実施の形態について、図１〜図５を用いて説明する。なお、従来のディスク装置と同機能のものには同符号を付す。図１（ａ）および（ｂ）は本発明の一実施の形態に係るディスク装置のトレイ収納状態の平面透視図および斜視透視図、図２（ａ）および（ｂ）は同ディスク装置の、トレイ収納状態のままトレイが排出方向に比較的小さな衝撃による加速度を受けた場合の平面透視図および斜視透視図、図３（ａ）および（ｂ）は同ディスク装置の、トレイ収納状態のままトレイが排出方向に比較的大きな衝撃による加速度を受けた場合の平面透視図および斜視透視図である。
【００１５】
図１〜図３において、ハウジング１はディスク装置の外装部を構成するものであり、コンピュータ等の電子機器に搭載される場合の、電子機器本体とディスク装置との接続部となる。ディスク装置の使用時には、図１に示すように、トレイ２がハウジング１の内部に収納されている。
【００１６】
図１〜図３に示すように、ハウジング１内の奥部には、トレイ２がハウジング１内に収納された際にその一端５ａが当接して変位し、トレイ２をハウジング１から排出する方向に付勢するトレイ排出付勢部材５が配設されている。また、トレイ２における手前部分寄りの箇所には、軸６ａを中心に回動可能な係合部６が設けられており、この係合部６の先端の爪部６ｂは、ハウジング１側に取り付けられた被係合部１０に係脱自在とされている。また、係合部６は、トレイ２側に設けられている駆動部８（簡略的に示している）により回動され、トレイ収納状態では、駆動部８により係合部６を被係合部１０に係合する姿勢に保持しており、これによりトレイ２が排出されることを規制している。
【００１７】
被係合部１０は、ハウジング１に立設された支持軸１０ａを中心として回動可能に設けられており、ハウジング１上に形成された規制軸１ａによって時計方向の回動範囲を規制されている。また、支持軸１０ａにはバネ部材９が外装されている。バネ部材９の一端は、ハウジング１上に形成された係止軸１ｂに係止され、バネ部材９の他端は、被係合部７に与圧をもった状態（付勢力を与えた状態）で係合するように設けられている。このバネ部材９により被係合部１０は支持軸１０ａを中心として時計方向に付勢され、トレイ排出付勢部材５がトレイ２を付勢する力よりも大きな付勢力で被係合部７を規制軸１ａ側に押し付けている。駆動部８はトレイ２中に設けられ、係合部６と被係合部１０とが係合する状態に保持しており、これによりトレイ２が排出されることを規制している。
【００１８】
このように、トレイ２が収納されている状態において、排出方向に比較的小さな衝撃による加速度を受けて、トレイ２に加えられた力とトレイ排出付勢部材５がトレイ２を付勢する力との和が、バネ部材９が被係合部１０を規制軸１ａに押し付る力を超えると、図２に示すように、バネ部材９が変形される。そして、バネ部材９の変形により、バネ部材９により被係合部１０を付勢する力が増加し、トレイ２に加えられた力とトレイ排出付勢部材５がトレイ２を付勢する力との和と、バネ部材９の付勢力とが等しくなる位置で均衡する。この動作により、瞬間的に比較的大きな力を受けてもこの力が緩められる。トレイ２への加速度が取り除かれると、バネ部材９が被係合部１０を付勢する力が、トレイ排出付勢部材５の付勢力より大きくなるため、トレイ２は図１に示す状態まで戻される。
【００１９】
また、トレイ２が収納されている状態において、排出方向に比較的大きな衝撃による加速度を受けて、トレイ２に加えられた力とトレイ排出付勢部材５がトレイ２を付勢する力との和が、バネ部材９が被係合部１０を規制軸１ａに押し付る力を超えた際も、図３に示すように、バネ部材９が変形される。そして、バネ部材９の変形により、バネ部材９により被係合部１０を付勢する力が増加するが、この際に、トレイ２に加えられた力とトレイ排出付勢部材５がトレイ２を付勢する力との和が、バネ部材９の付勢力よりも大きいような、大きな衝撃の力が作用した場合には、被係合部１０が大きく回動して、係合部６と被係合部１０の係合が解除され、トレイ２はハウジング１より排出される。トレイ２が排出されるとバネ部材９により被係合部１０は再び規制軸１ａに押し付けられる。この後、通常のトレイ収納動作により、図１の状態に戻すことができる。
【００２０】
このように、トレイ２が収納状態において排出方向に小さな衝撃による加速度を受けた場合だけでなく、大きな衝撃による加速度を受けた場合でも、係合部６や被係合部１０が破損することを防止することができ、この結果、トレイ２を収納状態に保持することができなくなってディスク装置が使用できないなどの不具合を生じることを防止できる。
【００２１】
なお、以上の説明では、被係合部１０がバネ部材９によって付勢される構成を説明したが、これに限るものではなく、図４に示すように、被係合部１０自体がトーションスプリングからなるバネ部材であってもよく、このバネ部材９に係合部６が直接係合する構成でも同様に実施可能である。また、図５に示すように、被係合部１０自体が板ばねからなるバネ部材である構成でも同様に実施可能である。これらの、図４、図５に示す構成によれば、被係合部１０自体がバネで構成されているので、被係合部１０として別途にバネ部材９を設ける場合に比べて部品点数を減らすことができて、ひいては製造コストを低減させることができる。
【００２２】
また、上記実施の形態においては、被係合部１０側がバネ部材９やそれ自身のバネ性で弾性変形する場合を述べたが、これに代えて、係合部６がバネ部材やそれ自身のバネ性で弾性変形するように構成してもよく、さらには、被係合部１０および係合部６の両者がバネ部材やそれ自身のバネ性で弾性変形するように構成してもよい。
【００２３】
【発明の効果】
以上のように本発明によれば、ディスク装置がコンピュータ等の電子機器に搭載された状態で、その電子機器の落下等により、トレイに排出方向に大きな加速度がかかったときでも係合部、被係合部が破損することを防止できる。したがって、トレイを収納状態に保持することができなくなってディスク装置が使用できないなどの不具合を生じることを防止でき、信頼性が向上する。

Those having the same functions as those of the conventional disk device are given the same reference numerals. 1A and 1B are a plan perspective view and a perspective perspective view of a tray storage state of a disk device according to an embodiment of the present invention, and FIGS. 2A and 2B are trays of the disk device. FIGS. 3A and 3B are a perspective plan view and a perspective perspective view when the tray receives acceleration due to a relatively small impact in the ejection direction in the storage state. FIGS. It is the plane perspective view and perspective perspective view at the time of receiving the acceleration by a comparatively big impact in the discharge direction.
[0015]
1 to 3, a housing 1 constitutes an exterior part of a disk device, and serves as a connection part between the electronic device main body and the disk device when mounted on an electronic device such as a computer. When the disk device is used, the tray 2 is accommodated in the housing 1 as shown in FIG.
[0016]
As shown in FIG. 1 to FIG. 3, a direction in which one end 5 a abuts and is displaced at the back of the housing 1 when the tray 2 is stored in the housing 1 and the tray 2 is discharged from the housing 1. A tray discharge biasing member 5 for biasing is provided. Further, an engaging portion 6 that is rotatable about a shaft 6a is provided at a position near the front portion of the tray 2, and a claw portion 6b at the tip of the engaging portion 6 is attached to the housing 1 side. The engaged portion 10 can be engaged and disengaged. Further, the engaging portion 6 is rotated by a driving portion 8 (shown in a simplified manner) provided on the tray 2 side, and the engaging portion 6 is engaged by the driving portion 8 in the tray storage state. 10, and the tray 2 is controlled to be discharged.
[0017]
The engaged portion 10 is provided so as to be rotatable about a support shaft 10 a erected on the housing 1, and a clockwise rotation range is restricted by a restriction shaft 1 a formed on the housing 1. Yes. A spring member 9 is externally mounted on the support shaft 10a. One end of the spring member 9 is locked to a locking shaft 1b formed on the housing 1, and the other end of the spring member 9 is in a state in which a pressure is applied to the engaged portion 7 (a state in which a biasing force is applied). ) To be engaged. The engaged portion 10 is urged clockwise around the support shaft 10 a by the spring member 9, and the engaged portion 7 is urged by an urging force larger than the force by which the tray discharge urging member 5 urges the tray 2. It is pressed against the regulating shaft 1a side. The drive unit 8 is provided in the tray 2 and holds the engagement unit 6 and the engaged unit 10 in an engaged state, thereby restricting the tray 2 from being discharged.
[0018]
Thus, in the state in which the tray 2 is stored, the force applied to the tray 2 and the force with which the tray discharge urging member 5 urges the tray 2 in response to a relatively small acceleration in the discharge direction. If the sum exceeds the force by which the spring member 9 presses the engaged portion 10 against the regulating shaft 1a, the spring member 9 is deformed as shown in FIG. Due to the deformation of the spring member 9, the force that biases the engaged portion 10 by the spring member 9 increases, and the force applied to the tray 2 and the force that the tray discharge biasing member 5 biases the tray 2. Is balanced at a position where the urging force of the spring member 9 becomes equal. By this operation, even if a relatively large force is momentarily applied, this force is relaxed. When the acceleration to the tray 2 is removed, the force by which the spring member 9 biases the engaged portion 10 becomes larger than the biasing force of the tray discharge biasing member 5, so that the tray 2 returns to the state shown in FIG. It is.
[0019]
Further, in the state in which the tray 2 is stored, the sum of the force applied to the tray 2 and the force by which the tray discharge urging member 5 urges the tray 2 due to a relatively large acceleration in the discharge direction. However, also when the spring member 9 exceeds the force that presses the engaged portion 10 against the regulating shaft 1a, the spring member 9 is deformed as shown in FIG. The force of biasing the engaged portion 10 by the spring member 9 increases due to the deformation of the spring member 9. At this time, the force applied to the tray 2 and the tray discharge biasing member 5 When a large impact force is applied such that the sum of the urging force and the urging force of the spring member 9 is larger, the engaged portion 10 rotates greatly and the engaging portion 6 and the engaged portion are engaged. The engagement portion 10 is disengaged and the tray 2 is discharged from the housing 1. When the tray 2 is discharged, the engaged portion 10 is again pressed against the regulating shaft 1a by the spring member 9. Thereafter, the state shown in FIG. 1 can be restored by a normal tray storing operation.
[0020]
Thus, not only when the tray 2 receives acceleration due to a small impact in the ejection direction in the storage state, but also when the acceleration due to a large impact is received, the engaging portion 6 and the engaged portion 10 are damaged. As a result, it is possible to prevent problems such as that the tray 2 cannot be held in the storage state and the disk device cannot be used.
[0021]
In the above description, the configuration in which the engaged portion 10 is urged by the spring member 9 has been described. However, the configuration is not limited to this, and the engaged portion 10 itself is a torsion spring as shown in FIG. A spring member made of the above may be used, and a structure in which the engaging portion 6 is directly engaged with the spring member 9 can be similarly implemented. Further, as shown in FIG. 5, the configuration can be similarly implemented even in a configuration in which the engaged portion 10 itself is a spring member made of a leaf spring. According to these configurations shown in FIGS. 4 and 5, since the engaged portion 10 itself is configured by a spring, the number of parts can be reduced compared to the case where the spring member 9 is separately provided as the engaged portion 10. This can reduce the manufacturing cost.
[0022]
Moreover, in the said embodiment, although the to-be-engaged part 10 side described the case where it elastically deformed by the spring property of the spring member 9 or itself, it replaces with this and the engaging part 6 replaces the spring member or itself You may comprise so that it may elastically deform with spring property, and also you may comprise so that both the to-be-engaged part 10 and the engaging part 6 may elastically deform with a spring member or its own spring property.
[0023]
【The invention's effect】
As described above, according to the present invention, even when the disk device is mounted on an electronic device such as a computer and the tray is subjected to a large acceleration in the ejecting direction due to dropping of the electronic device or the like, It can prevent that an engaging part breaks.
