<p>PURPOSE:To sense a click when a cassette is inserted and to insure and excessive load against being given by instantaneously increasing the force of inserting a cassette tape at any stroke after a cassette insertion start detection switch acts. CONSTITUTION:When the cassette tape is pushed, a 1st slide member 17 moves further, and a slide switch engaged with the member 17 is turned ON to turn a drive gear 28 clockwise. A 2nd slide member 16 moves in the same moving direction as the 1st slide member 17. If the cassette tape is pushed quickly with a great force, elastic members 18 and 42 engaged with the 1st slide member 17 act against the 2nd slide member 16 in recess. Hence an extremely large tensile load is given to the 1st slide member 17, whereby a user instantaneously feels an increase in insertion force. Thus that increase is sensed as a click to reduce unnecessary insertion strokes.</p> |
