WATER DISCHARGE DEVICE AND PHOTOELECTRIC SENSOR
PROBLEM TO BE SOLVED: To provide a water discharge device and a photoelectric sensor that with a simple configuration, suppress electromagnetic noise incident from the front of a light receiving element.SOLUTION: A water discharge device comprises: a water discharge unit including a water discharge port for discharging water; a water supply passage for guiding water from a water supply source to the water discharge port; an on-off valve for opening/closing the water supply passage; a photoelectric sensor that emits detection light, receives reflection light of the detection light, and outputs a reception signal corresponding to the amount of received reflection light; and a control unit that detects the existence of an object on the basis of the reception signal and, depending on a detection result of the object, controls opening/closing of the on-off valve. The photoelectric sensor includes: a sensor body including a light emitting element for emitting the detection light, and a light receiving element for receiving the reflection light; and a conductive member that is formed in a sheet shape to cover the front of the light receiving element, has light permeability with respect to the detection light and the reflection light and conductivity, and electrically communicates with reference potential of the sensor body.SELECTED DRAWING: Figure 2
【課題】受光素子の前方から入射する電磁ノイズを簡単な構成で抑制した吐水装置及び光電センサを提供する。【解決手段】水を吐出する吐水口を有する吐水部と、給水源から前記吐水口に水を導く給水路と、前記給水路を開閉する開閉弁と、検出光を投光し、前記検出光の反射光を受光し、前記反射光の受光量に対応した受信信号を出力する光電センサと、前記受信信号を基に対象物の有無を検出し、前記対象物の検出結果に応じて前記開閉弁の開閉を制御する制御部と、を備え、前記光電センサは、前記検出光を投光する投光素子と、前記反射光を受光する受光素子と、を有するセンサ本体と、シート状に形成され、前記受光素子の前方を覆うとともに、前記検出光及び前記反射光に対する光透過性と導電性とを有し、前記センサ本体の基準電位と導通された導電部材と、を有することを特徴とする吐水装置である。【選択図】図２
