御手段とを具備したフオトセンサ装置。 A light receiving section that generates an electromotive force in response to light reception, an amplifier that amplifies the electromotive force from this light receiving section and outputs it as a detection output, and the electromotive force input to this amplifier is divided into two levels, large and small, according to a control signal. A control signal is given to the input switching circuit to switch to the higher level, and if the amplifier output at that time is greater than a certain value, it is determined that high illuminance light is being received and the input switching circuit is set to the lower level. control means for supplying a control signal for switching to the higher level, and determining that low illuminance light is being received if the amplifier output at that time is smaller than the predetermined value, and supplying a control signal for switching to the higher level to the input switching circuit; Equipped with a photo sensor device.
