Abstract
An improved disc cassette having a shutter-closeable aperture, wherein the shutter is moved against the force of a confined coil compression spring into an aperture-open condition and is there latched by a transversely deflectable latch pawl normally biased into latching position and operable by manual pinching of the cassette to release the pawl to permit the spring to return the shutter to the aperture-closed position.
