Tape cassette loading and unloading apparatus having a lock mechanism.

摘要

A tape cassette loading and unloading apparatus comprises a holder (l5) which is inserted with a tape cassette (l2), a belt-driven transmitting mechanism (25) for moving the holder between a cassette receiving position and a predetermined loading position via an insertion completion position, a lock mechanism (26, 27) for locking the transmitting mechanism when the holder reaches the predetermined loading position so that the holder is immovably locked in the predetermined loading position, and a pushing member (34) for pushing a top surface of the tape cassette as the holder moves from the insertion completion position to the predetermined loading position so as to hold the tape cassette in a loaded position when the holder is in the predetermined loading position.
