Abstract
A disc cartridge includes a shutter member movably supported by a cartridge main body accommodating a disc and provided with an aperture for laying a part of the major surface to outside across the inner periphery and the outer periphery of the disc, and a holding member having its proximal side rotatably supported within the cartridge main body and adapted for holding the shutter member in a position of closing the aperture. The shutter member includes a plate portion for opening and closing the aperture of the cartridge main body, a mating engaging portion engaged by a part of the free end of the holding member, an inserting portion adapted for being inserted into a shutter opening groove provided in a lateral side of the cartridge main body and a connecting portion for connecting the plate portion and the inserting portion to each other. The shutter section, the mating engaging part, the inserting portion and the connecting portion are formed integrally from a metal material or a synthetic material. When the shutter member is moved to a position closing the aperture in the cartridge main body, the mating engaging portion of the shutter member is engaged with and maintained by the free end of the holding member for maintaining the aperture in the closed state. When the disc cartridge is loaded in position in the disc recording and/or reproducing apparatus, the shutter opening member provided in the disc recording and/or reproducing a apparatus is intruded into the shutter opening groove of the cartridge main body for rotating the holding member for disengaging the mating engaging portion of the shutter member from the holding member and simultaneously moving the shutter member in a direction of opening the shutter member.
