Claims

[Scope of utility model registration request]

(1) Consisting of a tape drive device that runs the tape at a constant speed and a supply control circuit that controls the supply of the audio signal superimposed on the bias signal to the recording head, when recording the audio signal on the tape, A tape recorder wherein the supply control circuit is configured to pass the audio signal after starting the drive.

(2) The supply control circuit has a time constant circuit that is supplied with a signal for operating the tape drive device and delays the signal for a predetermined time, and after being supplied with the signal delayed by the time constant circuit. A tape recorder according to claim 1, which allows the audio signal to pass through.

(3) The supply control circuit has a tape running speed detection device that detects when the tape running speed has reached a predetermined constant speed, and detects passage of the audio signal based on the detection output of the tape running speed detection device. A tape recorder according to claim 1, which controls the utility model.
