Abstract
A disk cartridge shutter opening and closing mechanism which is disclosed herein is designed to open and close a shutter of a disk cartridge having a variety of disks contained in a shuttered hard case and is of a construction having a pair of arms swingably mounted within a range of a width of the disk cartridge, the arm having a block which is pivotally mounted on its leading end and integrally formed with an engage head portion and an arm portion which are used for opening and closing of the shutter. The pushing-in of the disk cartridge causes the pair of arms to be swung toward each other, thereby opening and closing the shutter. A smaller pushing-in force enables the shutter to be smoothly opened and closed. Moreover, the whole mechanism is thin and compact.
