PURPOSE: A display apparatus of operation for a raindrop sensor in a wiper is provided to prevent accidents and breakage by stopping the operation of the wiper before traveling for automatically washing. CONSTITUTION: A microprocessor(3) detects the operational state of a wiper switch(1) and a raindrop sensor(2), and actuates or stops a wiper motor(5) intermittently, or at low or high speed. The raindrop sensor is connected to the microprocessor, and a display unit(4) is installed in an output terminal of the microprocessor. The operation of the wiper is displayed on the display unit by the microprocessor in the sensor mode. The wiper is stopped before traveling for automatically washing. Accidents and breakage are prevented by restricting operation of the wiper during washing automatically.
