<p>PURPOSE:To simplify the structure by surely performing locking and unlocking of the cassette holder in its loading position and locking of a head drum in its position withdrawn from the inside of a tape cassette only by a cassette holder and a head drum withdrawal lever. CONSTITUTION:The cassette holder is formed with a part 46d to be locked, and the head drum withdrawal lever 16 is provided with a lock part 121. When the cassette holder 44 is in its loading position, the lock part 121 of the head drum withdrawal lever 116 is positioned undernearth the part 46d to be locked of the cassette holder to prevent the cassette holder from moving to the ejecting position side. When the head drum drum withdrawal lever 116 is withdrawn, its lock part 121 is deviated from a turning locus of the apt 46d to be locked, and the cassette holder is moved to its ejecting position, and then the part 46d to be locked is positioned in front of the lock part 121 to prevent the head drum withdrawal lever 116 from returning, thus holding the head drum 21 in its withdrawn position. By this method, only one operating member is enough, so that the structure can be simplified.</p> |
