摘要:
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.

A sheet processing device includes an upstream device, a downstream device, and a controller as circuitry. The upstream device includes multiple rollers to convey a sheet in a conveyance direction and perform a sheet processing. The downstream device is downstream from the upstream device in the conveyance direction. The downstream device includes a sheet sensor to detect the sheet. The controller controls a timing to rotate the multiple rollers of the upstream device to perform the sheet processing in response to a detection of the sheet by the sheet sensor.

A sheet folder includes a conveyor conveying a sheet, a first folding roller and a second folding roller that form a first nip, a third folding roller forming a second nip with the second folding roller, a first guide movable between a first guide posture and a first retracted posture, a second guide movable between a second guide posture and a second retracted posture, and a motor. The motor rotates the second folding roller forward to convey the sheet toward the first nip, reverse to convey the sheet toward the second nip, moves the first guide to arrange in the first guide in the first guide posture or the first retracted posture, and moves the second guide to arrange the second guide in the second guide posture or the second retracted posture.

A sheet folding apparatus includes a conveyor, a first folding roller, a second folding roller, a third folding roller, a guide, a motor, and a driving force transmission mechanism. The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.

A cutting device is configured to cut, in an arc shape, an end of a sheet conveyed in a conveyance direction. The cutting device includes an arc-shaped cutting blade; a switching mechanism; and a contact-and-separation mechanism. The switching mechanism is configured to switch a posture of the cutting blade in accordance with a position of the sheet facing the cutting blade. The contact-and-separation mechanism is configured to bring the cutting blade into contact with the sheet in a contact direction orthogonal to a surface of the sheet and away from the sheet in a separation direction opposite the contact direction, to cut the end of the sheet in the arc shape.

A sheet processing device includes: a folder that forms a plurality of folds on a sheet such that a fold part and a part with no fold of the sheet overlap with each other; a conveyance unit that conveys the sheen on which the folds are formed by the folder; and a pressing part that presses the fold part of the conveyed sheet in which the fold part and the part with no fold overlap with each other, from a side on which the fold part is located.

A sheet processing device includes a conveying unit, a presser, an end detector, and a setting unit. The conveying unit conveys a sheet having a crease formed therein. The presser presses the crease in the sheet. The end detector detects an end in a conveying direction of the sheet at a position upstream of the presser in the conveying direction. The setting unit sets a crease position where the crease is to be formed. Upon detection of the end in the conveying direction, the conveying unit conveys the sheet to a position where the crease faces the presser, on the basis of the crease position set by the setting unit. The presser presses the crease in the conveyed sheet.

A sheet folding apparatus includes: a first sheet conveying unit; a second sheet conveying unit that is disposed downstream of the first sheet conveying unit; a folded part forming unit that forms a folded part on a sheet by nipping a turned-back portion formed on a part of the sheet between the first sheet conveying unit and the second sheet conveying unit; a second conveying path that bifurcates from the first conveying path and in which a sheet with the folded part is conveyed; and a pushing member that is movable between a pushing position at which the pushing member pushes the turned-back portion toward the folded part forming unit and a retracted position. The pushing member also serves as a changing unit that changes a direction of a leading end of the sheet that is conveyed in the first conveying path into a direction toward a second conveying path.

A sheet folding apparatus includes: a folded part forming unit that forms a folded part on the sheet by nipping a curved portion formed on a part of the sheet between an upstream first sheet conveying unit and a downstream second sheet conveying unit by holding a part of the sheet by the first sheet conveying unit and applying conveying force to the sheet to reverse the sheet upstream by the second sheet conveying unit; and a sheet leading end detection unit disposed downstream of or at almost same position as the second sheet conveying unit. The sheet is conveyed based on a detection timing of the sheet leading end detection unit such that the leading end of the sheet protrudes by a predetermined protrusion amount from the second sheet conveying unit immediately before applying conveying force to the sheet to reverse the sheet.

A sheet processing device includes: a conveying module that conveys a folded sheet; and a pressing module that presses a folded part of the folded sheet by rotating about a direction orthogonal to a sheet conveying direction of the conveying module as a rotation axis. The pressing module includes a projecting part arranged in a certain range in a direction of the rotation axis along a circumferential surface about the rotation axis. The projecting part is formed to be symmetric with respect to a middle part of the rotation axis in the direction of the rotation axis, and the projecting part arranged on one side from the middle part along the direction of the rotation axis are formed such that a position of the projecting part in a rotational direction of the circumferential surface varies along the direction of the rotation axis.
