PURPOSE:To obtain rapid returning operation of right and left mirrors by making the comparison processing executed by servo system programs of right and left mirrors between a present and a preset position of the mirrors alternately in right and left mirrors for controlling respective motors. CONSTITUTION:When an ignition switch 33 is on, a control program is executed by a microcomputer 36. In case a mirror returning flag is not set, one of channel switches is switched on. As the switch is on, data are transferred from respective preset position registers. Then, the mirror returning flag and horizontal returning flags of right and left mirrors are set. At first, a present position in horizontal direction of the right mirror is compared with a preset position of horizontal direction of the above-said register, and the right mirror is moved to the right or left until two positions are accorded. Similarly, the left mirror is processed to return to the right or left. Then, the right mirror is processed to return vertically in the same manner, and after that, the left mirror is processed to return vertically. |
