供給物の異常検出装置。 This is a device that detects an abnormality in the supply state of a supply in a device that supplies a sheet-like supply with a pattern printed on the front side and a blank back side, and is placed on the back side of the supplied supply to detect the An optical feed presence/absence detector is placed on the surface side of the feed to detect the pattern of the image printed on the surface of the feed using reflected light corresponding to the pattern printed on the surface of the feed. A pattern detector receives signals from these detectors and detects whether or not the signal from the supply presence/absence detector and the pattern pattern signal from the pattern detector have a predetermined correspondence relationship. , and a detection circuit that outputs an abnormality signal when these relationships do not meet a predetermined relationship.
