Floppy disk drive having improved frame means

Claim 1

A floppy disk drive having a path extending longitudinally from the front thereof for the insertion and removal of a magnetic medium and comprising: a base; a spindle rotatable about a spindle axis; a magnetic head carried by a carrier, said carrier being mounted for reciprocal motion across tracks on the magnetic medium; a frame having a substantially planar guide face opposed to said base for guiding the magnetic medium during insertion and removal thereof, said frame further comprising a forward wall extending transversely and perpendicular to said guide face at a forward edge of said frame, said frame further comprising a channel-like accommodating recess formed by an upper wall spaced from the plane of said guide face and first and second side walls extending between said guide face and said upper wall; a clamp for pressing the center of the magnetic medium against said spindle, means mounting said clamp for rotation and for axial sliding motion within said accommodating recess; said mounting means including a clamp arm mounted for pivotal motion between an operative and inoperative position within said accommodating recess of said frame and comprising means for pressing said clamp agagainst the magnetic medium in the operative position, said clamp arm further including a guide edge substantially coplanar with said guide face for further guiding of said magnetic medium during insertion and removal thereof in the inoperative position and means for moving said clamp arm, comprising an operating shaft supported on said forward wall of said frame and on said first and second side walls of said accommodating recess, and a cam mounted on said operating shaft for contacting and moving said clamp arm between said positions.
