Abstract: 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.

Abstract: 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.

Abstract: In an embodiment, a booklet conveying device includes: a pair of conveying units; a positioning unit; a pressing unit; and a conveying-force changing unit. The pair of conveying units convey a booklet made of a stack of folded sheets, and change a distance therebetween. The positioning unit positions the booklet by making a leading-end portion of the booklet abut thereto. The pressing unit presses the booklet positioned by the positioning unit onto one of the conveying units in order to fix. The conveying-force changing unit changes the conveying force exerted by the conveying units.

Abstract: A paper transport device is configured to independently drive a paper ejecting roller when predetermined abnormal events occur. When paper-jamming occurs and if no paper is present downstream of a jammed paper or a preceding paper that is present most downstream is located upstream of a predetermined position, the paper ejecting roller is stopped to prevent ejection of papers outside of the paper transport device. When paper-jamming occurs and if a preceding paper that is present most downstream is located downstream of the predetermined position, the paper ejecting roller is independently driven to complete ejection of the preceding paper.

Abstract: A processing unit performs a predetermined processing on a sheet in a process of carrying the sheet. A home-position detecting unit detects a home position of a moving member of the processing unit by detecting a part of the moving member using a detecting unit. The home-position detecting unit sets in advance a detection range for recognizing the home position, and when a part to detect the home position is detected in a state in which the moving member is stopped, sets a detection position as the home position by assuming that the detection position is in the detection range without moving the moving member once out of a detection range of the detecting unit.

Abstract: A sheet processing apparatus and associated method are provided. The sheet processing apparatus includes a sheet conveying path, a sheet stack tray, a sheet discharging member, a sheet guide member, and a sheet contact portion. The sheet conveying path is configured to convey a sheet, the sheet discharging member discharges the sheet to the sheet stack tray, and the sheet stack tray receives the sheet. The sheet guide member is movable from a first position that guides the sheet discharged from the sheet discharging member to a second position that opens a sheet discharge path of the sheet discharging member. The sheet contact portion is arranged at an upstream side of the sheet discharging member with respect to the sheet conveying path, and responds to the sheet conveyed through the sheet conveying path in order to move the sheet guide member between the first and second positions.

Abstract: A punching device includes a detecting unit, a punching unit, a moving unit, a storage unit, and a controlling unit. The detecting unit detects a lateral edge position of a recording medium to obtain edge position data. When the edge position data does not indicate an error value, the edge position data is stored in the storage unit as reference data. The controlling unit determines, when the edge position data indicates an error value, a movement amount of the punching unit based on reference data previously obtained and stored in the storage unit. The moving unit moves the punching unit by the movement amount in a direction perpendicular to the conveying direction of the recording medium.
