Claims

[Scope of utility model registration request]

In a tape recorder having a function of dubbing and recording a playback signal from a recorded magnetic tape onto an unrecorded dubbing magnetic tape, a playback signal presence/absence detection circuit for detecting the presence or absence of a playback signal from the recorded magnetic tape, and the playback signal a time constant circuit that is supplied with the detection output of the presence/absence detection circuit and outputs the detection output after a certain period of time has elapsed since the detection of the absence of the reproduction signal; A tape recorder comprising: a circuit for stopping the running of the dubbing magnetic tape from the time when a certain period of time has elapsed until the presence of the reproduction signal is detected again.
