<p>PURPOSE:To prevent the erroneous operation in cleaning control by arranging a light projector and a plurality of light receiving devices in the triangular measurement system for a human body and outputting the human body detection signal as distance information on the basis of the detection signal supplied from each light receiving device. CONSTITUTION:As for the reflection light which is formed by the reflection of the light supplied from the light projection element 4 of a sensor part 3 by a user 2, the position of the user 2 is detected through the triangular measurement system by the light receiving elements 5 - 9, and the detection signal is outputted into a detection area specification calculation circuit 10. Then, in the calculation circuit 10, the positioning area of the user 2 is calculated, and the area signals I1 - I5 are outputted into a control circuit 11. Then, in the control circuit 11, a solenoid valve 13 is opening/closing-driven through a valve driving circuit 12, and the control signal for the preparatory cleaning and substantial cleaning of a toilet bowl 1 for urine are outputted.</p> |
