ABSTRACT:
An image recording/reproducing apparatus is designed to be loaded with a cartridge accommodating a recording medium such as an optical or magnetic disk. The cartridge has a shutter which is automatically opened when the cartridge is mounted on the apparatus so as to enable the recording/reproducing portion of the apparatus to access the recording medium for the purpose of recording and/or reproduction. The apparatus includes a mechanism for automatically opening and closing the shutter in response to inserting and ejecting the cartridge. The mechanism includes a pair of swingable levers or shutter arms arranged symmetrically with respect to a line along which the center of the cartridge is moved during insertion. The free end of one of the swingable levers is adapted to be engaged by an engaging portion provided on the shutter of the cartridge so as to urge the shutter in the opening direction when the cartridge is inserted. When the cartridge is inserted in an inverted orientation, the engaging portion of the shutter is brought into engagement with the free end of the other swingable shutter lever so as to be urged in the opening direction which is opposite to the first-mentioned opening direction.
