A sheet bundle discharging apparatus including: a conveyance belt configured to convey and discharge a sheet bundle in a conveyance direction; an attitude changing unit configured to change an attitude of the sheet bundle from a first attitude in which the sheet bundle is apart from the conveyance belt to a second attitude in which the sheet bundle is placed on the conveyance belt; and a receiving member configured to receive an end portion of the sheet bundle, wherein the attitude changing unit allows the end portion of the sheet bundle to pass through a region in which the conveyance belt is provided, in a belt width direction perpendicular to the conveyance direction, and thereafter reach a region in which the receiving member is provided, a friction coefficient between the sheet bundle and the receiving member being smaller than a friction coefficient between the sheet bundle and the conveyance belt.

A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

A post-processing device includes a carrying roller, a conveying member, a transporting member and a processing part. The carrying roller is configured to be rotated to carry a sheet one by one to a processing tray along a conveyance direction. The conveying member is configured to convey the sheet carried by the carrying roller to a receiving position on the processing tray. The conveying member has a rotation shaft and a plurality of contact pieces protruding from the rotation shaft so as to come into contact with the sheet carried on the processing tray. The contact piece is made of elastic material. The conveying member is rotated at a rotation speed higher than a rotation speed of the carrying roller when the sheet carried by the carrying roller is conveyed to the receiving position on the processing tray.

A stapling apparatus including a holding portion that receives and holds a plurality of mediums, a first matching portion positioned downstream of the holding portion, a paddle that applies sending force to the mediums so that leading edge sides of the mediums reach the first matching portion, a stapler that binds the mediums, the leading edge sides of the mediums having been matched by the first matching portion, a folding mechanism portion that folds the mediums that have been bound by the stapler. In the stapling apparatus, the first matching portion is configured to move and is configured to transport the mediums to a performing position of the stapler and a performing position of the folding mechanism portion by moving, and a position where the paddle applies sending force to the mediums differs according to lengths of the mediums in a transport direction.

A booklet includes a cover including an integrally formed front cover sheet and a rear cover sheet connected by a hinge fold around which the front cover sheet is pivoted relative to the rear cover between a closed position and an open position, and at least first and second leaves therein. Each leaf includes at least one integrally formed leaf sheet and spine sheet connected together at a hinge fold. Upon pivoting the front cover sheet between a closed position and an open position, the interior leaves move relative to the front cover sheet and a step display tab area on each interior leaf is progressively revealed. A method of forming the booklet is also disclosed.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.
