Abstract
When a new paper sheet is supplied onto a compiling tray, a sub-paddle holds down paper sheets having already been stacked on the compiling tray until a leading edge of the new paper sheet S touches the stacked paper sheets. Thereafter, the sub-paddle gets apart from the sheets stacked on the compiling tray with timing, with which the rear edge of the new paper sheet falls on the compiling tray.
Claims9
A sheet processing apparatus comprising:
- a compiling tray that receives and stacks supplied sheets that have undergone a predetermined post-processing;
- a longitudinal reference wall that aligns said sheets supplied to said compiling tray by pushing a portion, not having undergone said predetermined post-processing, of each of said sheets;
- a longitudinal alignment unit that pushes said sheets on the longitudinal reference wall by acting on said portion, not having undergone said predetermined post-processing, of each of said sheets stacked on said compiling tray;
- a counting unit that counts said sheets supplied to said compiling tray;
- a longitudinal alignment assisting unit that moves in a thickness direction of said sheets according to a count obtained by said counting unit by acting on a portion having undergone said predetermined post-processing that conveys the sheets to the longitudinal reference wall and assists the sheet alignment performed by the longitudinal alignment unit,
- wherein said counting unit counts said sheets by converting one sheet of said sheets into n-sheets (n>1);
- and
- said longitudinal alignment assisting unit moves in said thickness direction of said sheets according to said count obtained by said counting unit when said longitudinal alignment assisting unit acts on said portion, having undergone said predetermined post-processing, of each of said sheets.
