PURPOSE: A motor returning control apparatus to an original point is provided to be capable of accurately controlling the synchronous of several motors by controlling the motors using simple switching circuits. CONSTITUTION: A first CCW(counterclockwise) limit sensor(20) and a first CW(clockwise) limit sensor(40) control the limits of a first motor(10). A second CCW limit sensor(60) and a second CW limit sensor(80) control the limits of a second motor(50). A first original point sensor(30) and a second original point sensor(70) controls the original points of the first/second motors(10,50). A motor controller(100) generates a pulse signal and a switching control signal for driving the motors in accordance with a controller(90). First/second switching parts(110,120) selectively supply/block the pulse signal output from the motor controller(100) in accordance with the switching control signal. First/second motor drivers(130,140) drive the motors(10,50) in accordance with the pulse signal selectively supplied from the first/second switching parts(110,120).
