<p>PURPOSE:To loosen the working accuracy of components and to reduce costs by providing a means which interlocks the movement of a holder lock lever with the movement of a sub-chassis. CONSTITUTION:When a cassette holder 4 is loaded, a projection 2b is provided at a sub-chassis 2 so that a holder lock lever 7 may not interlock with the operation of the cassette holder 4, a projection 7c of the holder lock lever 7 is engaged, and the movement of the holderlock lever 7 is interrupted by interlocking with the interruption of the sub-chassis 2. Further the interruption of the sub-chassis 2 by means of an interrupting mechanism 13 is released by the approach of the cassette holder 4 to a loading device, and the holder lock lever 7 is moved by interlocking with the movement of the sub-chassis 2. Consequently the timing of a magnetic head 3 to push the tape synchronizes with the timing of the cassette holder to arrive at a loading position. Thus the working accuracy of the components can be loosened, and the costs can be reduced.</p> |
