Description

【0001】
【発明の属する技術分野】
本発明は、記録媒体を搬送するトレイを備える記録再生装置に関する。
【0002】
【従来の技術】
図3に従来の記録再生装置の斜視図を示す。
また、図4にトレイとトレイの開閉機構の上面図を示す。
図3、図4において、記録再生装置前面の操作パネル1から図示していない光ディスクを装置内及び装置外に搬送するトレイ2がある。そして、トレイ2の前面部にはローダパネル3があって、操作パネル1に設けた操作ボタン4の操作でトレイ2を装置内に収納すると、ローダパネル3は操作パネル1に緩嵌する。
【0003】
トレイ2の裏面にはトレイ2を出し入れするためのラックギア2cが設けてある。そして、トレイ2を出し入れ自在に支持しているメカベース11には、トレイ2のラックギア2cと歯合する送りギア8bが取り付けてある。また、メカベース11には、送りギア8bに駆動力を伝達する送りギア8aと、送りギア8aに連結するベルト9と、モータ10があって、モータ10の駆動力が連結するベルト9に伝達され、ラックギア2cに伝達されるようになっている。
【0004】
上述した構成では、トレイ2を装置内に収納すると、ローダパネル3は操作パネル1に緩嵌するので、塵埃やたばこのタール等の侵入を防ぎ、光ピックアップ12のレンズ13に塵埃やたばこのタール等が付着するのを防止できる。しかしながら、操作パネル1に設けた操作ボタン4を操作して、トレイ2を装置内から装置外に移動させ停止位置で停止させると、操作パネル1とトレイ2との間に大きな開口部が形成されるので、この開口部から塵埃やたばこのタール等が侵入してしまう問題があった。
【0005】
特に、業務用に使用する記録再生装置等で、例えば2台の記録再生装置が交互に用いられる場合、一方の記録再生装置に次に記録または再生される記録媒体を載置し、トレイ2を突出させたままで待機させている使用状態があり、その待機状態が長時間続くことがある。
このような使用状況下では、光ピックアップ12のレンズ13に塵埃やたばこのタール等が付着しやすくなり、塵埃やたばこのタール等の付着によって光ディスクに情報の記録をすることや、光ディスクに記録された記録情報の読み取りを行うことができなくなってしまう問題があった。レンズ13に塵埃やたばこのタール等が付着すると、光ピックアップ12の取り替え等、大変手間のかかる修理をしなくてはならなかった。
【0006】
【発明が解決しようとする課題】
そのため本発明では、トレイを記録再生装置内から装置外に移動させ停止位置で停止させたときに、記録再生装置とトレイとの間に形成される開口部から記録再生装置内に塵埃やたばこのタール等の侵入を防止することができる記録再生装置を得ることを目的としている
【0007】
【課題を解決するための手段】
本発明の請求項1記載の記録再生装置は、記録媒体を載置するトレイと当該トレイを装置内部の位置と装置の前面に形成される開口部から突出する位置の間を搬送する搬送手段を備える記録再生装置において、前記トレイが前記開口部から突出したときに前記開口部を塞ぐ蓋部を備え、前記トレイは、前記記録再生装置から突出する部分に搬送方向に延出するリブを備え、前記蓋部は、前記記録再生装置の筐体に軸支されるとともに付勢手段で付勢されて前記トレイのリブに接触し、前記トレイを前記開口部から突出させたときに前記リブの端部から外れて前記開口部を塞ぐことを特徴としている。
【0008】
したがって、トレイを記録再生装置からトレイを突出させ所定の位置で停止させても、記録再生装置内に塵埃やたばこのタール等の侵入を防止することができる。
【0010】
また、蓋部が付勢されているので、トレイを記録再生装置からトレイを突出させ所定の位置で停止させたときに開口部を確実に塞ぐことができる。
【0011】
また、本発明の請求項2記載の記録再生装置は、請求項1記載の記録再生装置において、前記トレイの後端面にコ字状の切り欠き部を設け、当該切り欠き部に前記蓋部が遊貫して前記開口部を塞ぐことを特徴としている。
【0012】
したがって、蓋部のトレイとの隙間が少なくなって、開口部を確実に塞ぐことができる。
【0015】
また、本発明の請求項3記載の記録再生装置は、請求項1記載の記録再生装置において、前記リブは、前記トレイに載置した記録媒体の上面を越える高さを有していることを特徴としている。
【0016】
したがって、トレイに載置した記録媒体に蓋部材が接触して、トレイの搬送中にディスクをトレイから脱落させたり破損させることを防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording / reproducing apparatus provided with a tray for conveying a recording medium.
[0002]
[Prior art]
FIG. 3 shows a perspective view of a conventional recording / reproducing apparatus .
FIG. 4 is a top view of the tray and a tray opening / closing mechanism.
3 and 4, there is a tray 2 for transferring an optical disk (not shown) from the operation panel 1 on the front of the recording / reproducing apparatus into and out of the apparatus. A loader panel 3 is provided on the front surface of the tray 2. When the tray 2 is stored in the apparatus by operating an operation button 4 provided on the operation panel 1, the loader panel 3 is loosely fitted to the operation panel 1.
[0003]
On the back surface of the tray 2, a rack gear 2c for taking the tray 2 in and out is provided. A feed gear 8b meshing with the rack gear 2c of the tray 2 is attached to the mechanical base 11 which supports the tray 2 so that the tray 2 can be taken in and out. The mechanical base 11 includes a feed gear 8a for transmitting a driving force to the feed gear 8b, a belt 9 connected to the feed gear 8a, and a motor 10, and the driving force of the motor 10 is transmitted to the belt 9 connected. , Rack gear 2c.
[0004]
In the above-described configuration, when the tray 2 is stored in the apparatus, the loader panel 3 is loosely fitted to the operation panel 1, so that dust and tobacco tar and the like are prevented from entering and the lens 13 of the optical pickup 12 is attached to the dust and tobacco tar. Can be prevented from adhering. However, when the operation button 4 provided on the operation panel 1 is operated to move the tray 2 from the inside of the apparatus to the outside of the apparatus and stop it at the stop position, a large opening is formed between the operation panel 1 and the tray 2. Therefore, there is a problem that dust, tobacco tar and the like enter through the opening.
[0005]
In particular, when two recording / reproducing apparatuses are used alternately in a recording / reproducing apparatus used for business, for example, a recording medium to be recorded or reproduced next is placed on one of the recording / reproducing apparatuses, and the tray 2 is There is a use state in which the projector is kept on standby while being protruded, and the standby state may continue for a long time.
Under such usage conditions, dust and tobacco tar and the like tend to adhere to the lens 13 of the optical pickup 12, and the dust and tobacco tar and the like allow information to be recorded on the optical disc or to be recorded on the optical disc. This makes it impossible to read recorded information. If dust or tobacco tar adheres to the lens 13, it is necessary to perform very troublesome repairs such as replacement of the optical pickup 12.
[0006]
[Problems to be solved by the invention]
Therefore, in the present invention, when the tray is moved from the inside of the recording / reproducing apparatus to the outside of the apparatus and stopped at the stop position, dust or tobacco is introduced into the recording / reproducing apparatus from the opening formed between the recording / reproducing apparatus and the tray. It is an object of the present invention to obtain a recording / reproducing device capable of preventing tar or the like from entering.
[0007]
[Means for Solving the Problems]
The recording / reproducing apparatus according to claim 1 of the present invention comprises a tray on which a recording medium is placed, and a transport means for transporting the tray between a position inside the apparatus and a position protruding from an opening formed in the front of the apparatus. In the recording / reproducing apparatus, the lid includes a lid that closes the opening when the tray protrudes from the opening, and the tray includes a rib that extends in a transport direction at a portion protruding from the recording / reproducing apparatus, The lid is pivotally supported by a housing of the recording / reproducing apparatus and is urged by urging means to come into contact with the rib of the tray. When the tray is projected from the opening, an end of the rib is formed. The opening is closed off from the portion .
[0008]
Therefore, even if the tray is protruded from the recording / reproducing apparatus and stopped at a predetermined position, it is possible to prevent dust and tobacco tar from entering the recording / reproducing apparatus.
[0010]
Further, since the lid is urged, the opening can be reliably closed when the tray is projected from the recording / reproducing apparatus and stopped at a predetermined position.
[0011]
The recording / reproducing apparatus according to a second aspect of the present invention is the recording / reproducing apparatus according to the first aspect , wherein a U-shaped notch is provided on a rear end surface of the tray, and the lid is provided at the notch. It is characterized in that the opening portion is closed through free running.
[0012]
Therefore, the gap between the lid and the tray is reduced, and the opening can be reliably closed.
[0015]
According to a third aspect of the present invention, in the recording / reproducing apparatus according to the first aspect, the rib has a height exceeding an upper surface of the recording medium placed on the tray. Features.
[0016]
Therefore, it is possible to prevent the cover member from coming into contact with the recording medium placed on the tray and dropping the disk from the tray or damaging the disk while the tray is being transported.
