する複写機の紙通過検知装置。 A paper passage detection device including an optical sensor comprising a light emitter that emits light perpendicular to the conveyance direction on a conveyance path of transfer paper, and a light receiver that receives detection light from the light emitter, the light emitter and the light receiver. A light-shielding piece made of an opaque material is swingably provided between the two.
The light shielding piece is provided with a switching means that allows the light shielding piece to switch to a standby position in which the detection light passes through the light receiver when the transfer paper does not pass, and to switch to the light shielding position when the light shielding piece is pushed by the transfer paper when the transfer paper passes. A paper passage detection device for a copying machine, characterized in that:
