<p>PURPOSE:To carry a running tape to an object position with high accuracy without giving an adverse effect onto the tape by applying the multi-stage of deceleration to reel rotational speed near the object position of the tape. CONSTITUTION:When the stop object position of the tape 1 is a position giving the count of '100' by a counter 14 and a comparator 18 discriminates that the count of the counter 14 exceeds the count of '050' of a register 15, a flip- flop 20 is reset and the rotational speed of a winding reel 3 depends on a reference voltage outputted from a reference voltage generator 9. When it is discriminated that the count of the counter 14 exceeds the count '090' of the register 16, a flip-flop 21 is reset and the supply of a control signal to a motor driving circuit 10 is stopped. Since the reel rotational speed is decelerated with two- stage, the tape can be stopped at the object position without giving a load onto the tape and having the effect of the moment of inertia of the reel at tape stope.</p> |
