Claims

[Scope of Claim for Utility Model Registration] (1) An object detector that detects when an object such as a person enters or leaves a predetermined range in front of a urinal and outputs an electrical signal, and an object detector that outputs an electrical signal based on the output of the object detector. , when a predetermined remote control signal light emitted from a portable transmitter, which is separate from a control device body that performs water supply control such as outflow and stop of flush water to be flushed into the urinal, is received by the object detector. , stopping the water supply control of the washing water by the control device main body, or stopping the water supply control to restore the stopped water supply control;
The object detector of the water supply control device includes a return means, a light emitting element that emits a light beam in the direction of the object, a light receiving element that receives the light beam reflected by the object, and a light receiving element that receives the light beam that is emitted from the transmitter. and a remote control signal light receiving element that receives a predetermined remote control signal light, and the light emitting element, the light receiving element and the remote control signal light receiving element are arranged facing one window. Arrangement of light emitting and receiving elements in the object detector of the device. (2) Light emission in the object detector of the water supply control device according to claim 1 of the utility model registration claim, characterized in that the remote control signal light-receiving element is disposed at a central position between the light-emitting element and the light-receiving element. Arrangement of light receiving element. (3) The utility model according to claim 1, characterized in that the remote control signal light receiving element is attached so that the light receiving surface of the remote control signal light receiving element is parallel to the surface of the window. Arrangement of light emitting and receiving elements in the object detector of the water supply control device.
