PURPOSE:To obtain a current flowing direction control circuit which has a small size and an inexpensive cost by commonly using one of series unit of switching means for adjacent motors. CONSTITUTION:Series units of switching means 3, 4; 5, 6; and 7, 8 are connected in parallel between a positive power line 1 and a negative power line 2. A motor 11 is connected between the connecting points 9 and 10 of the switching means, and a motor 13 is connected between the connecting points 10 and 12, the motors 11, 13 are energized by eight power supply lines to be controlled in the rotating directions. A decoder 14 applies an output for suitably selecting the eight power supply lines for control terminals 3'-8' in response to the ON or OFF state of the switches 15-17. |
