ABSTRACT:
A clamp assembly is rotatably mounted to the dital end of a clamp arm proximally pivoted to the frame of the apparatus. The clamp arm is pivotable between an unclamping position, where the clamp assembly is away from a motor driven hub to allow the loading and unloading of a flexible magnetic disk in cartridge form, and a clamping position where the clamp assembly engages between itself and the drive hub the magnetic disk in a position for data transfer with a transducer head or a pair of such heads. The clamp arm is sprung from the clamping toward the unclamping position. Operatively engaged at a first end with the clamp arm is a clamp lever which is actuated as by a hand operated clamp knob for moving the clamp arm from the unclamping to the clamping position against the spring force. For simpler construction and easier assemblage, the clamp lever is made of sheet metal and formed to include a support portion bent right angularly from its second end. The support portion of the clamp lever is adapted to loosely but undetachably engage in an aperture or apertures in a flat lever mount rigidly attached to the frame, permitting the clamp lever to pivot substantially about its second end.
