ABSTRACT:
A cassette loading apparatus for a rotary drum deck comprises a movable plate-like member which is slidable relative to a stationary member. The two members are disposed on the drum deck with a top member of the drum deck therebetween. A symmetrical four bar linkage is connected between the movable member and the top member of the drum deck. The movable member is moved, under the guidance of fixed shaped slots formed on the side plates of the drum deck, along with a cassette holder into which a cassette is inserted, between an unloading position and a loading position by an actuation drive acting at one side of the cassette holder. The four bar linkage transmits the actuation to the other side of the cassette holder in a substantially synchronous way to make both sides of the cassette holder move symmetrically and synchronously and thus reducing the risk of jamming.
