Abstract:
A thin floppy disk drive comprising:a main frame in which a floppy disk having a shutter is inserted; an eject plate, mounted on said main frame slidably backward and forward, for ejecting said floppy disk inserted in said main frame, said eject plate having a plate stopper portion; a disk holder, mounted in said main frame, for holding said floppy disk, said disk holder moving up and down when said eject plate slides backward and forward; a disk shutter arm, rotatably mounted on said disk holder, for opening and closing the shutter of said floppy disk; and an eject lever, rotatably mounted on said main frame, having an eject stop part engaged with the plate stopper portion of said eject plate, said eject lever making said eject plate slide forwards by releasing engagement by the eject stop part to make said disk holder come down when said floppy disk is inserted in said thin floppy disk drive, the eject stop part of said eject lever being engaged with the plate stopper portion of said eject plate when said disk holder comes up on eject operation, wherein said eject lever has an eject protrusion, said disk shutter arm having a shutter hook part engaged with the eject protrusion so as to control a rotation operation of said eject lever when said floppy disk is not inserted in said thin floppy disk drive, thereby preventing said elect lever from rotating over a predetermined rotation angle as far as said floppy disk is not inserted in said thin floppy disk drive.
