Abstract
An apparatus and method for winding a magnetic tape into a cassette. The apparatus provides a simple construction that allows a leader tape to be smoothly and quickly withdrawn from the cassette. The apparatus has a motor mounted on a base panel with a winding shaft for engaging the hub of the cassette mounted on the spindle of the motor. A spring-loaded retractable pawl is mounted in a groove in the winding shaft. When extended by the spring, the pawl engages the hub of the cassette to wind magnetic tape into the cassette. The hub is released by retracting the pawl into the groove of the winding shaft with a reciprocally movable pressing plate mounted perpendicular to the axis of the winding shaft that engages the end of the pawl.
