ABSTRACT:
A disc cassette (1) has an outer case (4) with a front opening which is closed by a shutter (8) and latched in the case by a movable latching device. The apparatus has a device to release the shutter of an inserted disc cassette and with the aid of a withdrawal mechanism withdraws the shutter from the case when the case is withdrawn from the apparatus. The movable latching device for latching the shutter (8) in the case (4) comprises a movable part (14) of the case, and the release device of the apparatus comprises an insertion element (18A, 18B) which penetrates between the shutter and the case when the loaded disc cassette is inserted, thereby moving the movable part of the case to a free position in which the shutter is no longer latched in the case.
