ABSTRACT:
A stop command detecting unit detects an operation transition from fast forwarding/rewinding modes to a stop mode, a take-up side reel braking unit and a supply side reel braking unit start a braking operation based on the stop command, and a driving motor of the take-up side reel is driven at a specified current value set by a motor current value setting unit for a specified time set by a current adding time setting unit to provide the take-up side reel with rotary torque in the winding direction. Hence, the supply side reel rotates together with the take-up side reel until the supply side reel is stopped, thereby preventing occurrence of a slack on the tape.
