Abstract (en)
[origin: EP1970335A2] A sheet abnormality detection apparatus includes a plurality of abutting members (112,142,236) which move upon coming into contact with at least one of sheets conveyed to overlap while being shifted from each other in a convey direction and an object attached to a sheet. The plurality of abutting members (112,142,236) are disposed side by side in a direction perpendicular to a sheet convey direction. The apparatus also includes an abnormality detection unit which detects a sheet abnormality on the basis of a relative positional shift among the plurality of abutting members (112,142,236). A sheet abnormality detection method is also disclosed.
