Description

この発明はディスク装置に係わり、特にそのメカニズムシャーシ固定構造に関する。   The present invention relates to a disk device, and more particularly to a mechanism chassis fixing structure thereof.

従来のＣＤプレーヤやＤＶＤプレーヤ等のディスク装置では、ディスクモータ、光ピックアップやディスクトレイ等がメカニズムシャーシに支持され、このメカニズムシャーシがメインシャーシに固定されている。ディスクトレイはディスクローディングに用いられ、前面パネルのディスク挿入口から出入自在にメカニズムシャーシに支持されている。   In a conventional disk device such as a CD player or a DVD player, a disk motor, an optical pickup, a disk tray, and the like are supported by a mechanism chassis, and the mechanism chassis is fixed to the main chassis. The disc tray is used for disc loading, and is supported by the mechanism chassis so as to be able to enter and exit from a disc insertion port on the front panel.

図５に上記従来のディスク装置のメカニズムシャーシ固定構造の例を示す。図に示すメインシャーシ３には前面パネル４が固定されている。ディスクモータおよび光ピックアップを支持し、さらに、ディスクトレイ２を前面パネル４のディスク挿入口から出入自在に支持するメカニズムシャーシ１の後部はメインシャーシ３に締着された第１のステー５に固定されている。   FIG. 5 shows an example of a mechanism chassis fixing structure of the conventional disk device. A front panel 4 is fixed to the main chassis 3 shown in the figure. The rear portion of the mechanism chassis 1 that supports the disc motor and the optical pickup and further supports the disc tray 2 so as to be freely inserted and removed from the disc insertion opening of the front panel 4 is fixed to a first stay 5 fastened to the main chassis 3. ing.

ディスクトレイ２と前面パネル４のディスク挿入口との取付けの寸法精度を高めるためにメカニズムシャーシ１の前部は前面パネル４に締着された第２のステー６に固定されている。   The front portion of the mechanism chassis 1 is fixed to a second stay 6 fastened to the front panel 4 in order to increase the dimensional accuracy of the attachment between the disk tray 2 and the disk insertion slot of the front panel 4.

上記した従来のディスク装置のメカニズムシャーシ固定構造では、メカニズムシャーシの取り付けが簡単かつ少ない部品点数で行われている。しかしながらメカニズムシャーシの前方が取付けられている前面パネル４は上下方向の変形に対して剛性が小さいため、加振されると大きく振動し、また、メカニズムシャーシ自身で発生した振動も減衰しにくいという問題があった。このため、メカニズムシャーシの振動が音質に悪影響を与えていた。   In the mechanism chassis fixing structure of the conventional disk device described above, the mechanism chassis is easily attached with a small number of parts. However, since the front panel 4 to which the front of the mechanism chassis is attached has low rigidity against vertical deformation, the front panel 4 vibrates greatly when vibrated, and the vibration generated in the mechanism chassis itself is difficult to attenuate. was there. For this reason, the vibration of the mechanism chassis adversely affects the sound quality.

実開平６−８４５９７公報に提案された記録再生装置は、メカニズム本体と一体化されシャーシの支持部に締着されるブラケットに設けた押圧片とシャーシの支持部とでプリント基板を挾持している。   The recording / reproducing apparatus proposed in Japanese Utility Model Laid-Open No. 6-84597 holds a printed circuit board between a pressing piece provided on a bracket integrated with a mechanism body and fastened to a supporting portion of a chassis, and the supporting portion of the chassis. .

しかしながら、実開平６−８４５９７公報に提案された記録再生装置ではメカニズム本体が前面パネルに固定されたステーで固定されていない。従って、この記録再生装置はディスクトレイと前面パネルのディスク挿入口との取付けの寸法精度を高めることができない。
実開平６−８４５９７公報、段落００１０、段落００１１、図１、図２ However, in the recording / reproducing apparatus proposed in Japanese Utility Model Laid-Open No. 6-84597, the mechanism main body is not fixed by a stay fixed to the front panel. Therefore, this recording / reproducing apparatus cannot increase the dimensional accuracy of the attachment between the disc tray and the disc insertion slot of the front panel.

Further, since the front portion of the mechanism chassis 1 is fixed to the third stay 7 fastened to the main chassis 3, the vibration of the mechanism chassis 1 is suppressed.

図１に示す実施例のディスク装置と図５に示す従来のディスク装置との耐振動特性を比較するために、本発明のメカニズムシャーシ１と従来のメカニズムシャーシの各々３箇所に上下方向の加速度９８００ｍｍ／ｓ2 で振動周波数を変化させ加振し各測定点（図１および５に示すＡ点：センター、Ｂ点：左前方、Ｃ点：右前方）の加振周波数の加速度を測定した。加速度は加振方向を＋で表し、加振方向と逆方向を−で表した。結果を第２図の表および図３および図４に示す。図３は実施例の装置の測定結果を示すグラフであり、図４は従来例の装置の測定結果を示すグラフである。 To compare the anti-vibration characteristics of the conventional disk device shown in disk device and FIG. 5 of the embodiment shown in FIG. 1, the acceleration of the up and down direction and the mechanism chassis 1 in each three conventional mechanisms chassis of the present invention The vibration frequency was changed at 9800 mm / s 2 and vibration was applied, and the acceleration at the vibration frequency at each measurement point (point A: center, point B: left front, point C: right front shown in FIGS. 1 and 5) was measured. In the acceleration, the excitation direction is represented by +, and the direction opposite to the excitation direction is represented by-. The results are shown in the table of FIG. 2 and FIGS. 3 and 4. FIG. 3 is a graph showing the measurement results of the apparatus of the example, and FIG. 4 is a graph showing the measurement results of the apparatus of the conventional example.

図２の表に示すように、実施例のものは従来例のもの比較して第１次共振点（約８２Ｈｚ）での振動加速度が約１／２に低下している。さらに、図３および図４から第１次共振点以上の周波数でも実施例のものは従来例のもの比較して振動加速度が大幅に抑えられている。このように振動が抑えられるため、メカニズムシャーシ自体で発生する振動も抑えられ高度の音質特性が得られた。   As shown in the table of FIG. 2, the vibration acceleration at the first resonance point (about 82 Hz) in the example is lower to about ½ than in the conventional example. Further, from FIG. 3 and FIG. 4, the vibration acceleration of the example is significantly suppressed as compared with the conventional example even at frequencies higher than the primary resonance point. Since vibration is suppressed in this way, vibration generated in the mechanism chassis itself is also suppressed, and high sound quality characteristics are obtained.

実施例のものは第２のステー６と第３のステー７が共通のねじでメカニズムシャーシ１に締着されているので、組立て工数が削減され、また、省スペース化が可能となる。   In the embodiment, since the second stay 6 and the third stay 7 are fastened to the mechanism chassis 1 with a common screw, the number of assembling steps can be reduced and the space can be saved.
