PROBLEM TO BE SOLVED: To appropriately perform the processing of a magnetic reproducing signal and a perforation signal by one control means by performing the processing of either of the magnetic reproducing signal and the perforation signal in the midst of performing the processing of the other signal. SOLUTION: When the rising of the perforation PR2 signal is detected, a series of processing is performed after a fixed waiting time elapses. When the change (change to falling after detecting the rising) of the perforation PR1 signal is detected in the course of a series of processing, a series of processing is finished and the arithmetic operation and the decision of an effective value are performed. As a result, in the case of deciding that it is an exposed frame but not a final frame, preparation for detecting a next frame is performed. In the case of detecting that it is an unexposed frame, preparation for stopping is performed. Thereafter, the PR1 signal is detected continuously. When the rising is detected, whether or not motor driving is actually stopped is judged. Thus, the magnetic reproducing signal and the perforation signal are appropriately detected by one control circuit.
