Claims

[Scope of utility model registration request]

It has at least a playback function, and detects a no-signal part between signals of music or the like recorded on a magnetic tape in a fast-forward or rewind state, and when a set number of such no-signal parts is detected, the fast-forward or rewind A first tape recorder having a song selection function for canceling the return state and switching to the playback state, and a second tape recorder for recording the signal reproduced by the first tape recorder onto a magnetic tape are built into the same cabinet. In the tape recorder, a signal reproduced by the first tape recorder is applied, and a no-signal portion detection circuit detects a no-signal portion between the signals, and first and second dubbing circuits are switched in conjunction with each other during a diving operation. With the switch,
A song selection number setting switch for setting the number of songs to be selected, an up terminal to which a signal from the song selection number setting switch is applied via a first dubbing switch when in a non-dubbing state, and a signal from the no-signal portion detection circuit. has a down terminal to which is applied via a second dubbing switch, a switching signal output terminal to output a switching signal when the count value becomes zero due to down counting, and an output terminal to output a signal according to the count number. It consists of a counter, a switching circuit that operates when a switching signal is output from the switching signal output terminal to cancel the fast forward or rewind state and switch to the playback state, and a display that displays the count number of the up-down counter. , when in the dubbing state, the output signal of the no-signal portion detection circuit is applied to the up terminal of the up-down counter by switching the first dubbing switch, and the number of songs played by the first tape recorder is displayed on the display. A display circuit for a tape recorder, characterized in that a display is displayed on a device.
