ABSTRACT:
An operating lever is pivotally mounted on a floppy disc drive intermediate its ends, and has its one end exposed externally of the unit to serve as an operating handle while its other end is connected to a link. The link is connected to a motion mechanism which translates an oscillating motion into a rectilinear reciprocating motion. The reciprocating motion mechanism includes a movable element which is integral with a member that carries a floppy disc. In response to an oscillation of the operating lever, the movable element reciprocates together with the handle member of the floppy disc, whereby the floppy disc can be inserted into or removed from a given clamped position. Another link is connected to the other end of the operating lever and is connected to motion translating means which causes a clamp member to reciprocate in a direction perpendicular to the plane in which the operating lever oscillates, thus clamping or unclamping the floppy disc as the operating lever oscillates. The operating lever is associated with a detent or lock/unlock mechanism which locks the floppy disc at angular positions corresponding to insert limit and/or clamp limit assumed in the drive unit or releases or unlocks the disc.
