ABSTRACT:
A shutter opening and device includes movable components such as a lever, an actuating pin and a spring all disposed in a guide channel of a cartridge holder 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 incorporated. With the combination of a straight guide groove and an oblique guide groove formed in the cartridge holder, the actuating pin is movable along a substantially straight path. This enables the user to insert the disk cartridge into the cartridge holder smoothly with a small muscular effort.
