複写機の自動露光量調整装置。It has a light source that emits light onto the document being carried in, and a transmitted light amount detection sensor that detects the amount of light that has passed through the document, and the document that is conveyed to the exposure and printing drum based on the detection signal of the transmitted light amount detection sensor is superimposed. In a device that automatically adjusts the amount of exposure to photosensitive paper that is in close contact with the photosensitive paper, the transmitted light amount detection sensor is provided on the side of an electric circuit section constituting the device, one end facing the light source and the other end facing the transmitted light amount detection sensor. 1. An automatic exposure amount adjustment device for a copying machine, comprising an optical fiber that is disposed opposite to each other and transmits an amount of light transmitted through the document to the transmitted light amount detection sensor.
