監視装置において、 搬送される感光紙の非感光層面の方向に光を照
射する発光手段と、 前記発光手段に対向して配設されるとともに上
記発光手段の光が感光紙の通過により遮断あるい
は入射される受光手段と を備えることを特徴とする感光紙搬送監視装置。 (2) 搬送される感光紙の非感光層面の方向に光
を照射する複数の発光手段と、 上記複数の発光手段の光が夫々に入射されるべ
く対向して配設される複数の受光手段と、 上記感光紙が搬送される際に一方の受光手段に
対する発光手段からの光が遮断され、且つ、他方
の受光手段に対する発光手段からの光が入射され
ることにより感光紙の搬送が異常であることを検
知する検知手段と を備えることを特徴とする感光紙搬送監視装置。[Claims for Utility Model Registration] (1) A photosensitive paper conveyance monitoring device for monitoring the conveyance of photosensitive paper, comprising: a light emitting means for irradiating light in the direction of a non-photosensitive layer surface of the photosensitive paper being conveyed; and the light emitting means. 1. A photosensitive paper conveyance monitoring device comprising: a light receiving means disposed opposite to the light emitting means, and the light from the light emitting means is blocked or incident upon passing through the photosensitive paper. (2) A plurality of light-emitting means that irradiate light in the direction of the non-photosensitive layer surface of the photosensitive paper being transported, and a plurality of light-receiving means disposed facing each other so that the light from the plurality of light-emitting means is incident on each of the light-emitting means. When the photosensitive paper is transported, the light from the light emitting means to one of the light receiving means is blocked, and the light from the light emitting means enters the other light receiving means, so that the transport of the photosensitive paper is abnormal. 1. A photosensitive paper conveyance monitoring device comprising: a detection means for detecting a certain condition.
