    Abstract: The present invention provides a disc cartridge protecting member capable of closing a write and/or read aperture larger relative to the size of the disc cartridge and protecting a disc housed in the disc cartridge, such as optical disc used as an information recording medium. The disc cartridge protecting member includes an aperture closing plate which is to be fitted in, and to close, an aperture formed at one side of a disc cartridge having a disc housed rotatably therein and through which part of the disc is exposed to outside in a range between inner and outer radii thereof, an entry limiting portion supported on supports provided in the aperture formed in the disc cartridge to prevent the aperture closing plate from entering the disc cartridge, a cover plate extending on the other side of the disc cartridge opposite to the one side at which the aperture is formed, and a connecting plate to connect the base end of the aperture closing plate and that of the cover plate to each other. The protecting member is installed removably with the disc cartridge being held between the aperture closing plate and cover plate.

    Abstract: A disc recorder/reproducer (101) comprising a chassis (103) supporting a holder (102) containing a disc cartridge rotatably, an eject lever (105) provided on the chassis movably in the inserting/drawing direction of the di sc cartridge and movably in the approaching/receding direction to/from the chassis and being pushed by the disc cartridge (1) inserted into the holder to rotate, and a cartridge falling preventive means (221) for preventing the di sc cartridge (1) ejected by the eject lever (105) from falling off from the cartridge holder (102). The falling preventive means (221) is provided on on e side face (102b) of the holder and comprises a leaf spring for imparting a brake force to the disc cartridge by sliding on one side face (3b) thereof a t the time of discharging the cartridge. Consequently, the disc cartridge can be prevented from projecting from the cartridge holder and falling.
