動手洗装置。[Scope of Claim for Utility Model Registration] An automatic hand wash that performs predetermined operations such as discharging water based on human body detection by a reflective photoelectric sensor that receives reflected light emitted from a light projecting part at a light receiving part. In the device, a lens is provided on the light emitting section of the photoelectric sensor to narrow down the light beam from the light emitting section to a predetermined range centered on the optical axis of the light emitting section, and a lens is provided on the light receiving section to narrow down the light beam from the light emitting section. Narrowing down the range in which the reflected light can be received by the part to a predetermined range centered on its optical axis, and the irradiation range of the light projected from the light projecting part and the range in which the reflected light can be received by the light receiving part. An automatic hand washing device characterized in that the separation distance and direction of the light emitting part and the light receiving part are determined so that they overlap within a predetermined detection distance range and do not overlap outside the detection distance range.
