<p>A door (20) is pivotally mounted to a disk cartridge (1). Upon loading of the disk cartridge (1), an opening and closing pin (224) moving along a groove (223) engages with the door (20) to open the same. For example, in the case where the opening and closing pin (224) cannot return to a normal standby position for some reason, a front surface of the door (20) and a ridge (206) contact with each other, so that the disk cartridge (1) cannot be inserted farther on. Accordingly, even if the disk cartridge (1) is inserted with the door (20) being not opened, an accident, in which the disk cartridge could collide against a head, lamp or the like to cause damages, is prevented.</p> |
