ABSTRACT:
An apparatus for detecting tape running in a tape recorder includes an AND circuit to which are applied an output signal of a generator which produces an audio signal and an output signal from a tape running detector which detects the running of a magnetic tape and produces a fixed output signal when a tape end is reached. An output signal from the AND circuit which corresponds to the audio signal is applied to a loudspeaker contained within the tape recorder for audibly warning that a tape end has been reached.
