Title:
SHEET PROCESSING DEVICE, AND IMAGE FORMATION SYSTEM
Document Type and Number:
Japanese Patent JP2014144864
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a configuration that realizes high folding accuracy without depending on the number of folding sheets in conveying clearance whose amount of conveying clearance is widely set to be suitable for multiple folding, or a stack tray.SOLUTION: A movable move guide member 36 and a subsidiary guide member 37 are disposed on a saddle stitch conveying path 27. The move guide member 36 and subsidiary guide member 37 moves to an opposite side of a center folding roller 34, so that a position of a sheet P of a sheet bundle is restrained by the move guide member 36 and a guide surface facing thereto, and positional variations between the sheets are also regulated. A contact position between the sheet bundle and a folding blade 29 becomes uniform by pushing out the folding blade 29 in this state, so that variations in folding accuracy can be suppressed.
