The rearview mirror angle setting unit 200 controls the vertical rotation angle of the right rearview mirror motor 10 and the left rearview mirror motor 11 operated by the right rearview mirror motor control unit 70 and the left rearview mirror motor control unit 80. The left rearview mirror and the right rearview mirror positioning switches S2 and S3 are connected between the input ports RMB and LMB of the microcomputer 50 and the output terminals of the constant voltage generator 302 so as to be determined.

In addition, the power supply unit 300 switches the power output from the car battery 301 according to a control signal output from the output port REL of the microcomputer 50 when the automatic mode switch S1 is selected. An output terminal of the battery 301 is connected to the normal cross contact NC of the relay RY.

In the above, the input port BG of the microcomputer 50 resists the signal of the backward signal detecting unit 800 which turns on the reverse lamp of the vehicle when the shift lever is shifted to the reverse gear position 850 to reverse the vehicle. Licensed via (R7).

The electric exterior rearview mirror of the present invention configured as described above should first determine the angle at which the rearview rearview mirror and the rearview rearview mirror are automatically adjusted when the driver reverses the vehicle (S2, S3) of the rearview mirror angle setting unit 200. Press for a predetermined time, and the microcomputer 50 counts the time that the switches S1 and S2 have been connected and stores it in an area of a built-in memory.

When the driver connects the auto mode switch S1 in a state in which downward angles of the left rear mirror and the right rear mirror are set, the power output from the vehicle battery 301 is supplied through the constant voltage generator 302 and the auto mode switch S1. It is applied to the input port MB of the microcomputer 50. Then, the microcomputer 50 recognizes the automatic mode, outputs a high potential to the output port LED1, turns on the light emitting element L1 of the function mode display means 60, and high power to the output port REL. The above output is applied to the base terminal of the transistor Q11 of the power supply unit 300 to conduct the transistor Q11.
