Claims (1)

[Scope of utility model registration request] Left and right drive motors for rotating the left and right side mirrors of an automobile toward a first position by forward rotation and toward a second position by reverse rotation; and when the left and right side mirrors are respectively at the first position. left and right side first position detection switches that are turned off only when the left and right side mirrors are respectively in the second position; and left and right side second position detection switches that are turned off only when the left and right side mirrors are respectively in the second position, and an on command signal that is turned on only when externally operated. A momentary type operating switch that outputs , and a normally open contact that is turned on in the operating state in response to energization, and a normally closed contact that is turned on in the non-operational state in response to power outage, for the left side, right side and common. communication between the left side relay and the right side relay through the position detection switch which is in the on state among the left and right side first position detection switches which are provided to be turned on in response to the output of the on command signal. a first switching element that respectively forms an electric path; a first holding circuit that maintains the on state of the first switching element when at least one of the left and right relays is operated; When the ON command signal is output with both the right side first position detection switches turned off, the left and right side second position detection switches are turned on and are in the on state at this time.
a second switching element that forms an energization path for the common relay via a position detection switch; a second holding circuit that maintains the second switching element in an on state during an operation period of the common relay;
When the left side and right side second position detection switches are turned off while the common relay is in operation, the left and right side relays are operated, respectively, and the common relay is then switched to a non-operating state. and third and fourth switching elements that sometimes stop the operation of the left and right relays, respectively, and the left and right drive motors are rotated in the forward direction in each state in which the left and right relays are operated. The energizing paths for the left and right relays are formed through the normally open contacts of the left and right relays and the normally closed contacts of the common relay, and when the common relay is operated, the left and a mirror for an automobile, characterized in that the energization path for reverse rotation of the right side drive motor is formed through the normally open contacts of the common relays and the normally closed contacts of the left and right side relays, respectively. control device.
