Abstract
In a tape recorder, which has a circuit for producing pulses according to the running of a tape, there is provided an electronic counter circuit having a counter for counting pulses produced from that circuit and a display section for displaying the count. The electronic counter circuit includes a missing-pulse detector for detecting the pulse interval of the output pulse signal of the pulse generating circuit and producing a detection signal when the detected pulse interval exceeds a predetermined interval, a circuit for producing an alarm for a predetermined period of time according to the output signal of the missing-pulse detector, and a circuit for supplying a rotation stop signal to a motor of the tape recorder according to the output signal of the missing-pulse detector.
