PURPOSE:To facilitate a position control by activating the 1st and 2nd uneven bodies to be driven through a switch having a function capable of returning right after one action and putting positions in order. CONSTITUTION:A position controller used for right and left door mirrors Dr and Dl in an automobile is equipped with normally and reversely rotating motor drive circuits 1 and 51 as the 1st and 2nd drive means. Said circuits drive the right and left door mirrors Dr and Dl through motors mr and ml. Transistors 2, 3, 52 and 59, inverters 3, 10, 53 and 60, delay circuits 4 and 54, switches 5, 8, 55 and 61 and diodes 6-7, 12-13, 56-57 and 62-63 are connected to the both drive circuits 1 and 51, respectively. Through the pressing operation of the switch 8, the transistors 2 and 52 and those 9 and 59 are turned on and off, respectively. Thus motor (m) is driven and controlled so as to put positions such as neutral ones in order if the door mirrors D are independently located at front- and back-falling positions.
