A shutter opening and closing device includes movable components such as a lever (36), an actuating pin (41) and a spring (42) all disposed in a guide channel (35c) of a cartridge holder (35) into which a disk cartridge is inserted. The device of this construction is low in profile and compact in size and makes it possible to reduce the overall size of a disk drive in which the device is incorpo- rated. With the combination of a straight guide groove (39) and an oblique guide groove (40) formed in the cartridge holder (35), the actuating pin (41) is movable along a substantially straight path. This enables the user to insert the disk cartridge into the cartridge holder (35) smoothly with a small muscular effort.
