Control device for quick angle adjustment of rearview mirror

A control device for quick angle adjustment of a rearview mirror for controlling a quick angle adjusting mechanism which quickly changes a tilt angle of a mirror of a rearview mirror assembly for a vehicle so as to move the mirror between a normal position and a reverse position, the control device comprising:

• a direct current power supply for generating a direct current voltage;
• a quick angle adjusting motor for use in changing quickly and radically the tilt angle of the mirror;
• a reversible switch connected between said direct current power supply and said quick angle adjusting motor, said reversible switch being adapted to invert a direct current voltage from said direct current power supply in a forward or reverse direction to supply it to said quick angle adjusting motor;
• an operational switch for quick angle adjustment for use in operating said quick angle adjusting motor;
• reverse gear recognition means mounted on the vehicle to detect that a shift lever for changing gear positions is at a position corresponding to a reverse gear;
• a reversible switch circuit that connects said reversible switch in the forward direction only when said quick angle adjusting switch is turned ON after said reverse gear recognition means detects the shift lever is at the position corresponding to the reverse gear, and otherwise said reversible switch circuit connecting said reversible switch in the reverse direction;
• and
• a rotation control circuit that rotates said quick angle adjusting motor towards a reverse position side when said reversible switch is connected in the forward direction, and rotates said quick angle adjusting motor towards a normal position side when said reversible switch is connected in the reverse direction while said rotation control circuit disconnecting supply of a voltage to said quick angle adjusting motor when each rotation operation is terminated.
