Claims

[Scope of utility model registration request]

In a tape recorder that reproduces a tape recording signal at least when the tape is being played back and when the tape is running at high speed, the tape recorder includes an attenuator inserted and connected to a playback path, an attenuation drive circuit that drives the attenuator, and a tape an operation control circuit that outputs a signal during fast winding operation; a tape running detection circuit that detects the running state of the tape and outputs a signal; and an operation control circuit that operates the attenuator drive circuit based on the signal from the operation control circuit. and a control circuit for canceling the operation of the attenuator drive circuit based on the active signal from the playback running detection circuit.
