Abstract: The motor driving apparatus comprises a plurality of motors 11 to 14 for displacing the position of the control object member, semiconductor switch pairs 4 to 8, a plurality of motor driving units 21 to 23 for connecting the motors 11 to 14 to the power supply and a control unit 3 for ON/OFF controlling the semiconductor switch pairs 4 to 8. The motors 11 to 14 form two sets of motors with each set being formed of two motors. One end of the motors 11 to 12 and 13 to 14 forming each set is connected to the common motor driving unit 23 having the semiconductor switch pair 8 and the other end of the motors 11 to 12 and 13 to 14 forming each set is connected to the motor driving units 22, 23 having the semiconductor switch pairs 4 to 5, 6 to 7 in each set. When the motors 11 to 12, 13 to 14 of each set are driven simultaneously, the control unit 3 turns ON and OFF two semiconductor switch pairs 4 to 5, 6 to 7 and drives the motors of each set 11 to 12, 13 to 14 on the time division basis to provide inverse output polarities of the two semiconductor switch pairs 4 to 5, 6 to 7 connected to the motors 11 to 12, 13 to 14 of each set. Thereby there is provided a low price motor driving apparatus that has reduced the total number of motor driving units 11 to 13 using the motor driving units 21 to 23 having the semiconductor switch pairs 4 to 8.
