PURPOSE:To obtain an automatic angle change control device for a mirror cappable of looking at the proximity of the automobile tire by a mirror by automatically changing the angle of an electrically controlled mirror to directly downward and then inward of the automobile. CONSTITUTION:When all of the timer 4 for actuating period setting of the first motor for up and down drive, the timer 6 for actuating period setting of the second motor for left and right drive, and the timer 8 for rest period setting after the angle change are off, the pressing of a switch 1 actuates an angle change command circuit 2 to generate a negative trigger signal turning on the first and third timers 4 and 8 simultaneously. The second timer circuit 6 is turned on by a trigger signal generated at the moment the first timer 4 is turned from ON to OF. A gate circuit 8 makes a selection between the signals from the timers 4 and 6 according to the output signal from the timer 8 to give a signal for driving a mirror up and down and left and right to a circuit 10. When the switch is pressed while the third timer 8 is on the circuit 3 actuates to turn off the circuit 8. |
