A recording system includes a recording portion that performs recording on a medium, a stacking portion that stacks the medium recorded by the recording portion, and a processing portion that processes a bundle of media stacked on the stacking portion, in which a controller that controls feeding of the medium to the stacking portion determines a maximum number of sheets of media to be stacked on the stacking portion, based on information on swelling of the medium recorded by the recording portion.

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.

The cross-fold module for a folding machine comprises a cross-fold knife which is movable in a reciprocating manner in a folding-knife movement direction, and a pair of folding rollers which form a folding roller gap in which a sheet that previously was fed in the feeding direction is creased for folding by the cross-fold knife. A delivery transport device for the folded product receives the folded product in a receiving portion close to an outlet of the folding roller gap and transports the folded product to a delivery portion. At least the cross-fold knife and the pair of folding rollers are adjustable horizontally, perpendicular to the folding-knife movement direction and perpendicular to the feeding direction.

An image forming system includes an image forming apparatus including an image forming unit and a first control unit which controls the image forming unit, a varnish application apparatus provided downstream in a sheet conveyance direction with respect to the image forming apparatus and including a varnish application unit which applies varnish to a sheet and a second control unit which controls the varnish application unit, and a sheet conveyance apparatus provided between the image forming apparatus and the varnish application apparatus in the sheet conveyance direction and including a receiving roller which receives a sheet discharged from the image forming apparatus, a processing unit which performs predetermined processing on a sheet present in the sheet conveyance apparatus, and a third control unit which controls the processing unit, wherein the first control unit is capable of communicating with the second control unit and the third control unit.

A medium transporting apparatus includes a mounting portion configured to mount a medium, and a pressing portion configured to switch between a first state for pressing the medium against the mounting portion and a second state for releasing the medium. The pressing portion takes the first state in waiting for the medium to the mounting portion, switches to the second state in response to the sent medium and returns to the first state after the medium is sent to the mounting portion. When the last medium is mounted on the mounting portion, a timing at which the pressing portion returns to the first state from the second state is delayed with respect to the timing of the return therebefore.

A sheet folding apparatus includes a folding roller pair that forms a first fold line owing to that the folding roller pair nips a first position of the sheet, which has a loop to be formed on an upstream side of the folding roller pair due to continuous conveyance of the sheet by a conveyance roller pair in a stopped state in which a front end of the sheet being conveyed from the conveyance roller pair is nipped by the folding roller pair, as starting conveyance of the sheet while a pushing plate is pushing the sheet and moving toward the folding roller pair, and thereafter, forms a second fold line owing to that the folding roller pair nips a second position of the sheet with the loop formed as aligning with a rear end of the sheet.

A bending system for separating a page from a cover of a value document, wherein the page is connected to a spine of the cover, the spine separating the cover in first and second cover portions, wherein an angle γ is formed between the first and second cover portions. The bending system includes a bending unit connected to a motor, wherein the motor is configured to operate the bending unit such that the bending unit bends the value document to a first state, where γ is larger than 180°, and then back to a second state, where γ is at least 180° but less than γ in the first state, to separate the page from the cover. Also disclosed is an engraving system for engraving a front side and backside of a page of the value document and a document manufacturing device including the bending system and engraving system.
