<p>PROBLEM TO BE SOLVED: To eliminate illicit loading of a cassette deck. SOLUTION: A movable body 4 having a locking pawl 42 and an engaging piece 43 is mounted at a cassette receiving base 2. When the cassette 1 inserted into the cassette receiving base 2 pushes in an engaging part 43, the locking pawl 42 moves to an unlocking position. The front end of an activating member 5 consisting of a leaf spring is mounted at the eccentric point of the movable body 4 and its rear end is provided with an engaging piece 53. The cassette receiving base 2 is provided with a projection 6 and the activating member 5 is provided with a projection receiving part 54 and a recess 55. When the locking pawl 42 exists at the locking position, the projection 6 rides on the projection receiving part 54 and downwardly retreats the engaging piece 53. When the locking pawl 42 is positioned at the unlocking position by the insertion of the cassette, the activating member 5 moves forward and the projection 6 fits into the recess 55 and the engaging piece 53 rises to detain the rear end of the cassette.</p> |
