PURPOSE:To store eye points regarding rearview mirrors of a motor car for a long period stably to fluctuations of temperature even if a power source is turned off, by automatically shifting the mirrors in position until the digital signal output of a mirror position detector becomes equal to the digital signal output of a mirror storage setter. CONSTITUTION:When a storage position selecting switch 18 is changed over after the operation of a manual switch 11, the binary code output of a Gray code binary code decoder 16 and the binary code output of a setter for the storage of upper and lower position of a mirror are compared mutually by a level comparing circuit 14. Further, the binary code output of a Gray code binary code decoder 17 and the binary code output of a setter for the storage of the left and right positions of the mirror are compared by a level comparing circuit 15, thereby shifting the motor-driven remote-control mirror 12 in position until the comparison output is ceased. Thus, the switch 18 is changed over to automatically adjust the mirror position to eye points stored in the setters 9 and 10 for the mirror. |
