As a rotational reference position of a rotating drum is detected by a rotational position detection sensor for each rotation of the rotating drum, a rotational position of the rotating drum at a time of detection can be known. Subsequent to a signal for instructing stop of the rotating drum being input, the rotational reference position is detected. Then, a stop position calculation processing section calculates a stop control pulse for stopping the rotating drum from the rotational position at a trailing edge chuck detaching position. Thus, the rotating drum is reliably stopped at the trailing edge chuck detaching position. A stop processing is performed by a rotating drum drive control section when the rotational reference position is detected after the calculation. As a result, the stop position is not shifted by the time required for calculation and generation of the stop control pulse.
