回路。 When a song interval is detected in the input playback signal, the song interval detection waiter has a function of generating an inter-piece detection signal, and receives an input of the song-interval detection enable signal from the first input terminal. an inter-song detection I having a gate circuit that outputs the inter-song detection signal when it receives the inter-song detection signal at a second input terminal in the initial state;
an inter-song detection enable switch that is turned on at the same time as the inter-song detection mode is entered, and an inter-song detection enable signal that is connected to the first input terminal of the gate circuit; a time constant circuit connected between the song interval detection input/switching terminal of the song interval detection IC that receives an input; and a power supply from which the time constant circuit and the song interval detection IC are supplied with power. and a diode connected in the forward direction between the terminal and the song interval detection switch. A function signal is supplied to the first input terminal of the gate circuit through the song interval detection input/switching terminal of the song interval detection IC to place the gate circuit in the song interval detection standby state, and the song interval detection is completed. When the song interval detection enable switch is turned off, the charging voltage of the time constant circuit is guided to the song interval detection IC via the diode and the power supply terminal, and is discharged through the song interval detection IC. A tape recorder track interval detection circuit is characterized by the following.
