Abstract
A flexible magnetic disc drive apparatus comprising a housing including a front plate, a drive spindle rotatably mounted to the housing for rotatably driving a magnetic disc, an elongated frame including opposed rails, opposed first and second ends, and a crossbar extending between the rails and forming a stop, the frame being disposed over the spindle with its second end pivotally mounted to the housing, a latch hingedly mounted to the first end and coupled to the front plate such that the latch is movable between a closed and an open position, a spindle-clamping assembly, an elongated member formed of a resilient material and mounted to the frame proximate the first end such that its distal end is adapted to be engaged by the crossbar when the latch is moved to the open position, the member serving to carry the spindle-clamping assembly and to bias it towards the spindle, whereby when the disc is supported on the spindle and the latch is in the closed position, the member biases the spindle-clamping assembly against the spindle so as to clamp the magnetic disc therebetween, and whereby when the latch is opened and the frame is pivoted away from the spindle, the crossbar engages the member such that continued pivoting of the frame moves the spindle-clamping assembly out of clamping relationship with the spindle so as to allow the magnetic disc to be removed from the spindle.
