主权项

1. A folded sheet pressing device, comprising:
a folded sheet pressing unit configured to enhance a folded edge of a sheet subjected to a folding process; a pair of upstream guide plates which is disposed at an upstream of the folded sheet pressing unit in a sheet conveyance direction; a pair of downstream guide plates which is disposed in a downstream of the folded sheet pressing unit in the sheet conveyance direction; and a curving unit configured to curve the sheet in a sheet conveying direction when the sheet is supplied to the folded sheet pressing unit, wherein each of the pair of the upstream and downstream guide plates and the curving unit are aligned in the same horizontal plane which corresponds to the sheet conveying direction, wherein the curving unit is configured with guide members that are disposed so as to face each other and have curved surfaces that curve the sheet in the sheet conveying direction, and the sheet is configured to pass between the guide members that face each other, wherein at least one of the guide members is formed with a flexible member that has a plurality of holes arranged in the sheet conveying direction and is deformable, the folded sheet pressing device further including:
a plurality of support shafts configured to be inserted through the holes of the guide member, anda pair of support members having a plurality of holes configured to retain both end portions of the support shafts inserted through the holes of the guide member,wherein the both end portions of the support shafts are configured to be retained in a hole arbitrarily selected from the plurality of holes of the support members.
