PURPOSE:To prevent causing an operation error by cutting off a current respectively, when contrary operation commands have been given at the same time, in the circuit for controlling the direction of mirrors. CONSTITUTION:In case when the direction of the right and left back mirrors of a car, etc. is adjusted by means of a remote control, if the right side is adjusted, at first, the SW5 is switched to R. WHen the switch SW4 is closed, the transistor Tr1 becomes on and a current flow in the direction as indicated with an arrow. When the switch SW3 is closed, the transistor Tr3 becomes on and a current flows in the opposite direction to that which is indicated with an arrow. When both the switches SW3, SW4 are closed at the same time, the transistors Tr2, Tr4 become on, the transistors Tr1, Tr2 both become off, and an operation error is prevented. Relating to the switches SW1, SW2 for adjusting in other direction, too, the operation is all the same excepting the fact that the solenoid S12 for switching the clutch operates. |
