。A tape recorder with a reciprocating playback function, which has a playback function in a first direction and a playback function in a second direction opposite to the first direction, and is configured to allow manual switching of the playback direction. a first magnetic head for reproducing signals recorded on tracks in a first direction; a second magnetic head for reproducing signals recorded on tracks in a second direction of the magnetic tape; an amplifier circuit to which a signal reproduced by the first magnetic head is input when in a reproduction operation state, and to which a signal reproduced by the second magnetic head is input when in a reproduction operation state in a second direction; When the reproduction operation is in the first direction, the signal reproduced by the second magnetic head is input, and when the reproduction operation is in the second direction, the signal reproduced by the first magnetic head is input. , a no-signal portion detection circuit for detecting a no-signal portion between signals recorded on the magnetic tape, and a non-signal portion detection circuit that is turned on when in a playback operation state in the −1 direction, and a playback operation in the first direction. a first light emitting diode that indicates that a regeneration operation is being performed; and a second light emitting diode that lights up when the regeneration operation is in the second direction and indicates that the regeneration operation is being performed in the second direction. It consists of a diode and a blinking drive circuit that becomes operational when the no-signal area detection circuit outputs a detection signal associated with the detection of the no-signal area, and when the regeneration operation in the first direction is performed, When a no-signal portion is detected by the no-signal portion detection circuit, the second light emitting diode is made to blink by the output of the second blinking drive circuit, and when the reproduction operation in the second direction is being performed, the no-signal portion detection circuit 1. A display circuit for a tape recorder with a reciprocating playback function, characterized in that when a no-signal portion is detected, the first light emitting diode is caused to blink using the output of the blinking drive circuit.
