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. Besides, left and right solenoids SL and SR and left and right motors ML and MR are driven through a gate circuit 11 and a mirror drive circuit 12 and left and right mirrors 13 perform an angle change operation in the order of downward, temporary halt, and right or left direction. Each operation time is determined sequentially by the circuit T1-T3. When the 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 both mirrors perform a return operation and return to the original positions in the same way as the angle change operation. In this case, both motors are connected to the mirror drive circuit 12 through a single common wire and two wires. |
