PROBLEM TO BE SOLVED: To construct a sheet post-processing device compactly with a simple structure, possible to perform post-processing of selectively punching punched holes in a sheet on a carrying-in path and binding processing at a post-processing section on a downstream side, and post-processing of binding a sheet bundle at a manual set section arranged in an exterior casing.SOLUTION: A layout is as follows: a post-processing section is arranged, with a setting surface disposed on an exterior casing for inserting a sheet bundle to be subjected to binding processing from outside, and configured to stack and process the sheets sequentially carried into the casing, and a punch unit 100 is arranged for punching a punch hole on a carrying-in path, so that the punch unit and the setting surface are arranged with a space therebetween in an order of the punch unit and the setting surface in a sheet ejection direction and a height direction of a housing, and a moving area of the punch unit in a direction perpendicular to the sheet ejection and a sheet placing area of the setting surface overlap in the direction perpendicular to the sheet ejection.SELECTED DRAWING: Figure 3 【課題】搬入経路で選択的にシートにパンチ穴を穿孔し下流側の後処理部で綴じ処理する後処理と、外装ケーシングに配置したマニュアルセット部でシート束を綴じ処理する後処理が可能なシート後処理装置を簡単な構造でコンパクトに構成する。【解決手段】外部から綴じ処理するシート束を挿入するセット面を外装ケーシングに配置し、ケーシング内部に順次搬入されるシートを集積して処理する後処理部と、搬入経路にパンチ穴を穿孔するパンチユニット１００を配置する構成において、上記パンチユニットとセット面とをシート排紙方向とハウジングの高さ方向に、パンチユニット、セット面の順に距離を隔てて配置し、パンチユニットの排紙直交方向の移動領域とセット面のシート載置領域とを排紙直交方向に重畳的に重なり合うようにレイアウトする。【選択図】図３
