Abstract: To enable a sheet to be folded in an accurate position with a simplified folding mechanism in performing folding processing on the sheet with a pair of folding rollers, a second transport path is disposed in a direction for crossing a first transport path for guiding a sheet from a carry-in portion to a carrying-out portion, and in the cross portion are disposed a folding roller pair for performing folding processing on a sheet, and a folding deflecting member for inserting a fold of the sheet in the nip portion. Then, the folding deflecting member is comprised of a driven roller that comes into press-contact with a roller periphery of the folding roller pair, and a shift member for shifting the driven roller from a waiting position to an actuation position, and by the operation of shifting the driven roller from the waiting position outside the path to the actuation position, the sheet front end portion is fed to the nip portion from an upstream-side guide path formed in the second transport path.

Abstract: A sheet folding apparatus for forming first folding and second folding in a sheet enables the sheet to be folded in an accurate fold position in second folding, when the front end of the sheet which is first folded in a nip position of a first folding roller pair and transported strikes a stopper member, a guide member guides a fold to undergo second folding of the first-folded sheet to a nip position of a second folding roller pair, and second folding is formed.

Abstract: According to the present invention, a stacking face (84) is inclined such that a downstream side in a sheet discharging direction is lower, and is composed of a first supporting face (84a) supporting a sheet to be stacked at its front end part in a sheet discharging direction and a second supporting face (84b) supporting the sheet to be stacked at its rear end part in the sheet discharging direction. The first supporting face (84a) is structured to be shorter than ½ of a minimum size length of the sheet to be stacked, and this is provided rotatably upward around a rotating shaft (85x) furnished to a registration part (85r) of regulating the front ends of the sheets. The first supporting face (84a) raises the front ends of the sheets to be discharged by rotation of the registration part (85r).

Abstract: A sheet folding apparatus for performing folding processing, has a first transport path for guiding a sheet from a carry-in entrance to a carrying-out exit without performing the folding processing; a second transport path for performing the folding processing on the sheet from the carry-in entrance; and a folding processing device disposed in a folding position in the second transport path to fold the sheet from the carry-in entrance. The second transport path is disposed to cross the first transport path, and includes a path end portion for guiding the sheet to the folding position, and another path end portion for guiding the folded sheet from the folding position to a downstream side. The path end portion and the another path end portion are disposed opposite to each other relative to the first transport path.

Abstract: In a sheet folding apparatus, to enable a jammed sheet to be removed with ease when a jam occurs, a casing having a carry-in entrance and a carrying-out exit is divided into an upper unit and a lower unit via a first transport path for carrying a sheet from the carry-in entrance to the carrying-out exit, a second transport path for performing folding processing on a sheet is disposed in the direction for crossing the first transport path, and in the upper unit are disposed a sheet front end switchback path for reversing and carrying the sheet toward a folding roller pair and sheet deflecting means for guiding the sheet to the folding roller pair. Then, the upper unit is coupled to the lower unit to be openable and closable by a hinge shaft rotating around one side end portion orthogonal to the sheet transport direction of the first transport path.

Abstract: A sheet transport path extending from a carry-in entrance to a carrying-out exit is made small and compact in an apparatus configuration provided with a path without performing the folding processing and another path to perform the folding processing in between the carry-in entrance and the carrying-out exit. The configuration is provided with a first transport path 32 for guiding a sheet from the carry-in entrance 30 to the carrying-out exit 31 without performing the folding processing, a second transport path 33 for performing the folding processing on a sheet from the carry-in entrance, and folding processing means 48 disposed in the path 33 to fold the sheet.
