コーダーの再生方向表示回路。 In a tape recorder having a playback function in a first direction and a playback function in a second direction opposite to the first direction, when the tape recorder is in a state where playback is performed in the first direction, the tape recorder is in an open state and the playback function is in the second direction. a changeover switch that is closed when the changeover switch is in a state for regeneration; and a switch that is biased into a conductive state when the changeover switch is open and is nonconductive when the switch is in a closed state. a first transistor, a first light emitting diode which is connected as a load to the collector of the first transistor and whose lighting indicates that it is in the state of performing a regeneration operation in the first direction; and a base bias by the first transistor. a second transistor which is controlled and becomes conductive when the first transistor is non-conductive; and a second transistor which is connected as a load to the collector of the second transistor and whose illumination causes a regeneration operation in a second direction. A playback direction display circuit for a tape recorder with a bidirectional playback function, comprising a second light emitting diode for indicating a state in which playback is being performed.
