ーダーの動作制御回路。 A first tape recorder has a playback function and is equipped with an automatic stop device that switches to a stop state by detecting the end of the magnetic tape, and a reciprocating playback operation can be performed by rotationally displacing a rotary head using the rotational force of an electric motor. In a tape recorder in which a second tape recorder is installed in the same cabinet and is equipped with an automatic stop device that switches to a stop state by detecting the end of the magnetic tape, The first switch is closed when the playback operation button provided on the second tape recorder is locked in the operating position, and the switch is closed when the playback operation button provided on the second tape recorder is locked in the operating position. a second switch; a first electric motor that drives the magnetic tape of the first tape recorder; a second electric motor that drives the magnetic tape of the second tape recorder and rotationally displaces the rotary head; The operation of the first motor is controlled by a switch and a second switch, the first motor and the second motor are each connected as a load, and a transistor in a conductive state is connected to cause the other transistor to be in a non-conductive state.
a drive transistor, a second drive transistor, a playback direction changeover switch that is closed by a playback direction switching operation of the second tape recorder and is held in a closed state until the switching operation is completed;
a switching transistor that is biased and becomes conductive when the second electric motor is connected as a load and the reproduction direction changeover switch is in a closed state; and the second switch is in a closed state;
and a control transistor that is biased into a conductive state when the second drive transistor is in a non-conductive state and prevents the switching transistor from switching to a conductive state.
