<p>PURPOSE:To simplify the structure and to attain miniaturization by fitting directly a cassette lock device to a reel turntable support plate and using a torsional coil spring to engage directly a tail of a hook energized counterclockwise with a drive bar thereby using the tail of the hook projected from a through-hole as a manual lock release lever. CONSTITUTION:In moving a driver bar 28 to the left, a hook 27 is turned clockwise against the energizing force of the torsional coil spring 26. When a lock pin 14 of a cassette holder 2 is removed from the hook 27, the cassette holder 2 is lifted up by the energizing force of a tensile coil spring 11 to attain the state of loading/ejecting a cassette tape 1. When the hook 27 is turned clockwise further, an engaging claw 24b of a hook stop piece 24 is unlocked from an engaging projection 27c of the hook 27 and jumps up by the energizing force of the spring. In pressing a manual lock release lever 27b to the left, the lock state is released independently of the operation of the drive bar 28.</p> |
