<p><P>PROBLEM TO BE SOLVED: To provide a vehicle-mounted camera cleaning device that can perform the cleaning of a vehicle-mounted camera and a rear window simultaneously in a vehicle reverse travel state. <P>SOLUTION: When current flows into a back lamp BL to light the back lamp BL, a reverse travel signal BSG is output to a valve drive control circuit 30. When a washer switch SW1 is turned on from this state, a pump motor M2 is rotated and a washer signal WSG is output to the valve drive control circuit 30. The valve drive control circuit 30 energizes the energizing coil Bc of an electromagnetic selector valve B only for a preset time in response to the washer signal WSG. Then, when the washer switch SW1 is turned on, a rear wiper device and a motor pump 18 are driven and a second pipeline 8b comes in a state of continuity, causing the cleaning water which the motor pump 18 supplies to a main pipe 8 to be supplied to a rear washer nozzle N1 and a camera washer nozzle N2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
