Title:
A paper aftertreatment apparatus and an image forming device
Document Type and Number:
Japanese Patent JP6217690
Kind Code:
B2
Abstract:
A folding processing unit in a sheet post-processing device comprises a first conveying path, upstream side conveying rollers, downstream side conveying rollers, folding rollers between the upstream side conveying rollers and the downstream side conveying rollers, and the second folding rollers. The folding rollers fold a sheet at the first nip portion between the two rollers. The second folding rollers are placed at a downstream side of the first nip portion. An edge face detection sensor for detecting the edge face of the sheet is placed on the first conveying path, at a downstream side of the first nip portion. The second folding rollers pinch the sheet folded by the first nip portion at the second nip portion, to further fold the sheet, based on the detection result of the edge face detection sensor. Herewith, degree of accuracy for folding behavior improves.
