【００１８】
【課題を解決するための手段】
上述した問題を解決するために、本発明にかかるディスクカートリッジは、円盤状記録媒体が回転可能に収納されかつ上ハーフと下ハーフとにより構成されるカートリッジ本体と、このカートリッジ本体に設けられ、円盤状記録媒体を記録再生手段に臨ませる記録再生用開口部と、円盤状記録媒体を回転駆動するための駆動手段が進入する駆動用開口部と、これら記録再生用開口部と駆動用開口部とを開閉自在に設けられたシャッタ機構とを備える。かかるディスクカートリッジは、シャッタ機構が記録及び／又は再生用開口部を開閉し、駆動用開口部を開閉する第１のシャッタ部材と第２のシャッタ部材とを有する。かかるディスクカートリッジは、これら第１のシャッタ部材と第２のシャッタ部材とが、カートリッジ本体の主面上に設けられたシャッタ摺動凹部内において、同一平面に配置され、記録再生用開口部と駆動用開口部とを開閉動作する。かかるディスクカートリッジは、第１のシャッタ部材と第２のシャッタ部材とが、記録再生用開口部と駆動用開口部とを閉蓋した際に、少なくとも一方のシャッタ部材には、他方のシャッタ部材と重なるひさし部が設けられる。 0018
[Means for solving problems]
In order to solve the above-mentioned problems, the disc cartridge according to the present invention includes a cartridge body in which a disk-shaped recording medium is rotatably stored and is composed of an upper half and a lower half, and a disk provided in the cartridge body. A recording / playback opening for allowing the recording medium to face the recording / reproducing means, a driving opening for entering the driving means for rotationally driving the disk-shaped recording medium, and these recording / reproducing openings and driving openings. Is provided with a shutter mechanism that can be opened and closed. Such a disc cartridge has a first shutter member and a second shutter member in which a shutter mechanism opens and closes a recording and / or playback opening and opens and closes a driving opening. In such a disc cartridge, the first shutter member and the second shutter member are arranged on the same plane in a shutter sliding recess provided on the main surface of the cartridge body, and are driven by a recording / playback opening. It opens and closes with the opening. In such a disc cartridge, when the first shutter member and the second shutter member close the recording / reproducing opening and the driving opening, at least one of the shutter members has the other shutter member. Overlapping eaves are provided.
