Patent number: 11203505Abstract: A sheet folding processing device includes a folding processing mechanism that includes a folding roller pair for forming a plurality of folds on the sheet conveyed in a predetermined sheet conveying direction to produce Z-fold, additional folding rollers and a lower folding guide. The additional folding rollers and the lower folding guide are arranged on the downstream side of the folding roller pair in the sheet conveying direction to face each other and cooperate with each other to press the folds. The interval between the folding roller pair and the additional folding rollers is determined such that when the leading fold as viewed in the sheet conveying direction is pressed between the additional folding rollers and the lower folding guide, the sheet part having a plurality of layers of sheet where the sheet is folded between the additional folding rollers can also be held between the folding roller pair.Type: GrantFiled: December 10, 2019Date of Patent: December 21, 2021Assignee: CANON FINETECH NISCA INC.Inventor: Shinnosuke Enomoto
