Abstract
The disclosure describes a mechanism for loading and unloading cassettes or discs comprising a main frame, spaced side plates fixed on the main frame and having inverted L slots, and a movable frame between these side plates providing a magazine for a cassette or disc. The mechanism further comprises lateral members on the movable frame engaged in the inverted L slots and movable side plates associated with the fixed side plates and mounted on the main frame for rectilinear movement. The movable side plates have inclined slots which receive the lateral members. Further, the mechanism comprises a structure such as a rack and gear arrangement which interconnects the movable side plates for movement in unison. The inclined slots in the movable side plates act to guide the lateral members and the movable frame in a path defined by the inverted L slots between ejected and operating positions of the cassette or disc.
