載の感光紙検知装置。[Claims for Utility Model Registration] 1. Pass exposed photosensitive paper and original paper between a pair of rollers that are given a difference in circumferential speed, shift and separate the two papers from each other, and detect the length of the photosensitive paper. In order to achieve this, the diazo copying machine detects the leading edge of the photosensitive paper advancing towards the shifting device consisting of the pair of rollers, comprising a detection lever that is rotated by a predetermined angle by the leading edge of the advancing photosensitive paper, One end of this detection lever serves as a part for operating a first switch body for applying a rotational drive signal to the shifting device, and the other end serves as a part for operating a second switch body for detecting the leading edge of the photosensitive paper. A photosensitive paper detection device characterized by comprising a part that causes 2. The photosensitive paper detection device according to claim 1, wherein the second switch body is a photointerrupter, and the other end of the detection lever is an opening/closing portion of the optical path of the photointerrupter.
