る光電検出装置。 A photoelectric detection device that includes a light emitter and a light receiver that receives a beam of light emitted by the light emitter and outputs an electric signal according to the amount of the received light, and detects an object that blocks the beam of light based on the electric signal. In the above, both the light emitter and the light receiver include a housing formed in the shape of a hut with a gable roof and having a light transmitting window that is anti-fogging treated on one gable side side wall, and a housing that has one end that is connected to the light transmitting window. A cylindrical hood fixed to the one gable side wall so as to surround the window and protruding from the gable side side wall and having the other end cut off diagonally; and a cylindrical hood for heating the hood. an electric heater fixed to the outer surface of the hood, and a temperature controller that detects the temperature of the inner wall of the housing and controls the current flowing through the electric heater, and the light emitter further includes a light transmitting window. A light emitting mechanism is provided inside the housing to emit the light beam parallel to the axis of the hood through the light transmission window, and the light receiver further receives the light beam incident parallel to the axis of the hood through the light transmission window. A photoelectric detection device comprising a light receiving mechanism inside the housing.
