<p>PURPOSE:To prevent an accident of nipping finger with a lid or the overload of a motor, by reversing a loading motor in case the opening/closing time of the lid which is due to the leading-in or ejection of a tape cassette exceeds the normal necessary time that is previously set. CONSTITUTION:A control circuit 30 incorporated to a loading mechanism 7 of a cassette deck performs the control the start/stop or the forward/backward revolutions of a loading motor 16. The circuit 30 contains a comparator 30a that measures the time required for the leading-in and ejection actions of a tape cassette, i.e., the time required for the opening/closing of a lid 8 and then compares this measured time with the necessary time set previously and a reversing circuit 30b that reverses the motor 16 in case the opening/closing time of the lid 8 exceeds a desired time. As a result, the injury of a finger is avoided even if the finger is nipped by the lid 8 during a leading-in action by switching the lid 8 to an ejection state.</p> |
