ABSTRACT:
At the time of conveying a transfer printing belt-shaped material having known length and utilized in a tape recorder, a picture image forming apparatus or the like by an electric motor, the length of the belt-shaped material remaining after any point thereof is determined and displayed. The remaining length is determined by generating pulses in accordance with the rotation of the motor and then counting the number of pulses with a counter. Since the length of the belt-shaped material is known by correlating the length and the count of the counter with a computer the remaining length can be determined.
