<p>PURPOSE:To prevent a tape from running with a slack by applying signals from a tape slack fault detector switch and a tape running state control circuit to a circuit detecting the fault of the tape slack fault detection switch. CONSTITUTION:The tape stop state is detected by the tape slack fault detection switch 10 and the tape running state control circuit 20, and an active signal and an inactive signal are fed to the fault detection circuit 30 of the switch 10, and the circuit 30 detects the fault of the switch 10 based on both the signals. Thus, the running of tape with the slack is prevented.</p> |
