摘要:
A sheet processing apparatus includes a pair of squeezing members having a projection and a recess to engage each other, to squeeze a sheet bundle inserted therebetween in a direction of thickness of the sheet bundle, and a pressure applying unit to apply pressing force to the squeezing members to squeeze and bind the sheet bundle. The pressing force generated between the squeezing members by the pressure applying unit increases in strength as a relative distance between the squeezing members decreases.

A sheet processing apparatus includes a stacking channel to stack multiple sheets into a sheet bundle, and a binding device to bind together the sheet bundle, the binding device including multiple clamping portions to clamp the sheet bundle to create multiple clamping marks on the sheet bundle. When the binding device binds a corner area of the sheet bundle, a longitudinal direction of each of the multiple clamping marks forms an angle within a range from 30 degrees to 60 degrees with a side of the corner area of the sheet bundle.

A sheet processing apparatus includes a conveyance unit to transport a sheet bundle including multiple sheets in a sheet conveyance direction and a binding device including a clamping unit. The clamping unit includes multiple projections and multiple recesses to engage the respective projections to clamp the sheet bundle inserted therebetween. At least one of the multiple projections includes an inclined portion facing a sheet conveyance direction, and an inclination of the inclined portion is 45 degrees or smaller relative to a face parallel to the sheet conveyance direction.

A sheet processing apparatus performs predetermined processing on a sheet or a sheet bundle. The sheet processing apparatus includes: a conveying unit that conveys a sheet along a conveying path; an aligning unit that, each time a sheet is conveyed by the conveying unit, aligns the sheet; a stacking unit that reverses a conveying direction of a sheet to convey the sheet backward to a branch path branched from the conveying path, and stacks the sheet in the branch path; and a binding unit that binds a sheet bundle aligned by the aligning unit, in the conveying path.

A sheet processing apparatus includes a first binding unit configured to bind a sheet bundle; a second binding unit with greater number of bindable sheets than number of bindable sheets of the first binding unit; and a number-of-sheets determining unit configured to determine whether number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit. The first binding unit moves to a binding position, and if the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the first binding unit moves away from the binding position. When the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the second binding unit moves to the binding position.

A sheet processing device includes a stapling tray, a rear-end clamp, and a stapler that staples sheets while the rear-end clamp is clamping the sheets. In response to a start signal, the stapler moves to a position where the stapler does not interfere the rear-end clamp while being closest to a stapling position. When the last sheet of a sheet bundle to be stapled is conveyed into the stapling tray, timing at which the stapler moves to the stapling position is determined according to a preset condition.

A sheet processing apparatus includes: a pressing member that presses a fold part of a bundle of folded sheets so as to perform fold-enhancing; and a moving unit that moves a pressing position of the pressing member in a direction of a fold of the bundle of sheets. The moving unit starts pressing at an area located inside one end of the bundle of sheets while moving at a first velocity, and releases the pressing after passing through other end of the bundle of sheets during a forward movement, and starts pressing at an area located inside the other end of the bundle of sheets while moving at a second velocity that is higher than the first velocity, and passes through the one end of the bundle of sheets during a backward movement.
