Abstract: A media processing apparatus includes: an internal tray; an ejection tray; a first conveyor to convey a sheet medium in a first conveyance direction leading to the ejection tray via the internal tray; a second conveyor to convey the medium in a second conveyance direction; a binder including a pair of clampers to clamp sheet media stacked on the internal tray and being switchable among an out-of-contact state in which the clampers are out of contact, a clamping state in which the media are clamped by the clampers, and a binding state in which the media are pressed and bound by the clampers. The circuitry switches the binder into the clamping state when an (N+1)-th sheet medium is conveyed in the first direction while contacting an N-th sheet medium in a state in which N sheets of sheet media are stacked on the internal tray, N being a natural number.

Abstract: A sheet processing apparatus includes: an ejection tray; an internal tray; a first conveyor to convey a sheet medium in a first direction in which the sheet medium is ejected to the ejection tray; a second conveyor to come into contact with and separate from sheet media stacked on the internal tray to convey the sheet media in a second direction different from the first direction; a crimp binder downstream from the internal tray in the second direction to execute crimp binding on the sheet media stacked on the internal tray; and control circuitry. When a subsequent sheet medium, which is subsequent to a preceding sheet medium of the sheet media stacked on the internal tray, is conveyed in the first direction while contacting the preceding sheet medium, the control circuitry causes the crimp binder to press a downstream end of the preceding sheet medium in the second direction.

Abstract: A medium processing apparatus for processing a medium ejected from an image forming apparatus includes a conveyor, a slit, a medium processing device, a stopper, and detectors. The conveyor conveys the medium ejected from the image forming apparatus. The slit communicates with an opening of a housing into which a medium is manually inserted from outside and includes a placement face on which the inserted medium is placed. The placement face has a first side and a second side orthogonal to the first side. The first and second sides are not parallel to a direction in which a side face of the housing extends. The medium processing device processes the medium conveyed by the conveyor or the medium placed on the slit. The stopper regulates edges of the medium along the first and second sides of the placement face. The detectors are disposed on the stopper to detect the medium.

Abstract: A liquid application device for applying liquid to a plurality of media to be crimped by a crimping device includes a liquid applier and a liquid-applier moving mechanism. The liquid applier applies liquid to the plurality of media. The liquid-applier moving mechanism moves the liquid applier to a first position at which the liquid applier applies liquid to a medium on a conveyance path in the liquid application device and a second position at which the liquid applier applies liquid to the plurality of media inserted through a liquid application slit of the liquid application device.
