PURPOSE:To permit a driver to easily recognize the vicinity of a tire by changing the angle of left and right remote control mirrors downward and then inside a car. CONSTITUTION:When a switch SW is pressed, an angle change command circuit 2 is operated and the fourth timer circuit T4 goes on and then the first to third timer circuits T1-T3 go on sequentially. A solenoid SL and a motor ML are driven through a gate circuit 11 and a mirror drive circuit 12 and a mirror 13 performs an angle change operation in the order of downward, temporary halt, and right direction. These types of operation time are determined sequentially by the circuits T1-T3. When the switch SW is pressed again to return the mirror, a return command circuit 3 is operated and the circuit T4 is reset. The motor goes into reverse and the mirror performs a return operation and returns to the original position in the same way as the angle change operation. While the said operation is being controlled, since the circuits T1-T4 go on, the NOR1 is set to the low level (L) and the AND1 is also set to L. Besides, since a manual switch power circuit 15 goes off, power is not supplied to the manual switch circuit 14. |
