ジョブを構成するシートの枚数が、前記中折り手段で中折り可能な最大枚数Ｎを越える場合、前記ジョブを構成する複数のシートを複数のグループに分けるグループ分け手段と、
前記積載手段より上流の搬送経路に設けられ、前記シートを前記中折り可能な最大枚数Ｎより少ないＭ枚のシート束に重ね合わせる重ね合わせ手段と、
前記重ね合わされたシート束を前記積載手段に搬送する搬送手段と、
前記グループ毎に分けられたシートを積載して中折りするように、前記積載手段および前記中折り手段を制御するとともに、前記積載手段に積載された先行グループのシート束を中折りしている間、後続グループのシートを前記重ね合わせ手段で重ね合わせてシート束とし、前記先行グループの中折り終了後、前記重ね合わされたシート束を前記積載手段に搬送するように前記搬送手段を制御する制御手段とを備えたことを特徴とするシート処理装置。 A sheet processing apparatus for processing a sheet,
Stacking means for stacking the sheets into a sheet bundle;
A folding means for folding the stacked sheet bundle;
Number of sheets constituting the job, if the Ru exceeds the maximum number N that can be folded in the middle by a means folding in said, a grouping means for dividing the plurality of sheets constituting the job into a plurality of groups,
A superimposing unit that is provided in a transport path upstream of the stacking unit and superimposes the sheet on M sheet bundles that are smaller than the maximum number N of sheets that can be folded in half;
Conveying means for conveying the overlapped sheet bundle to the stacking means;
While controlling the stacking means and the center folding means to stack and fold the sheets divided for each group, and while folding the sheet bundle of the preceding group stacked on the stacking means A control unit that controls the conveying unit so that the subsequent group of sheets is superposed on the superimposing unit to form a sheet bundle, and the superimposed sheet bundle is conveyed to the stacking unit after the middle folding of the preceding group is completed. A sheet processing apparatus. 前記グループ分け手段は、最終シート１枚のみを前記積載手段に積載して中折りしないように、グループ分けを行うことを特徴とする請求項１記載のシート処理装置。   2. The sheet processing apparatus according to claim 1, wherein the grouping unit performs grouping so that only the last sheet is stacked on the stacking unit and is not folded in half. 前記中折りに要する中折り時間を算出する中折り時間算出手段を備え、
前記グループ分け手段は、前記ジョブを構成するシートの枚数が前記中折り可能な最大枚数Ｎを越えた場合、前記算出された中折り時間と前記シートを重ね合わせる枚数分の紙間時間の合計とを比較し、前記紙間時間の合計が前記中折り時間より長く、かつ前記重ね合わせ手段による重ね合わせ可能な上限枚数を越えない範囲で、前記グループの枚数を決定することを特徴とする請求項１または２記載のシート処理装置。 A middle folding time calculating means for calculating the middle folding time required for the middle folding;
When the number of sheets constituting the job exceeds the maximum number N of sheets that can be folded in half, the grouping means calculates the calculated half-folding time and the total time between sheets corresponding to the number of sheets to be overlapped. The number of sheets in the group is determined in a range in which the total time between the sheets is longer than the half-folding time and does not exceed the upper limit number of sheets that can be superimposed by the overlapping unit. The sheet processing apparatus according to 1 or 2 . 請求項１乃至３のいずれかに記載のシート処理装置と、前記シート処理装置で中折りすべきシートに画像形成を行い、画像形成されたシートを前記シート処理装置へ排出する画像形成装置とを備えたことを特徴とする画像形成システム。 4. The sheet processing apparatus according to claim 1, and an image forming apparatus that forms an image on a sheet to be folded in the sheet processing apparatus and discharges the image-formed sheet to the sheet processing apparatus.
