PROBLEM TO BE SOLVED: To provide a device that reduces binding stress to sheets when forming a sheet bundle and comparatively reduces movement of a sheet applied with an adhesive so as to eliminate adhesion of the adhesive to a part other than the sheet in a conveyance passage and a stack part and ensure attachment of a final paper sheet to a sheet already applied with the adhesive.SOLUTION: The sheet processing device comprises: an adhesive member 51 that applies an adhesive to a positionally regulated sheet and can be moved between a position to press the sheet and a position distant from the sheet to allow the sheet to be conveyed, in order to attach the sheet to a preceding sheet already applied with the adhesive; and a sheet pressing member 71 that is arranged adjacent to the adhesive member 51 and presses the sheet, and, when a sheet conveyed into a platen 79 is a final sheet subjected to adhesion processing, moves a position already applied with the adhesive to a pressing position of the pressing member 71 so as to press the sheet without applying the adhesive member to the sheet. 【課題】シート束を生成の際に、シートへの綴じストレスを小さくし、また、接着剤が塗布されたシートの移動を比較的少なくして、搬送路やスタック部でシート以外に接着剤が付着することをなくすとともに、最終紙シートと背着剤塗布済みのシートとの貼り合わせを確実に行わせる装置の提供。【解決手段】位置規制されたシートに対して接着剤を塗布するとともに既に接着剤が塗布された先行シートと貼り合せるためにシートを押圧する位置とシート搬入を許容するためシートから離間した位置との間で移動可能な接着部材５１と、この接着部材５１に隣接して配置され、シートを押圧するシート押圧部材７１とを有し、プラテン７９に搬入されるシートが接着処理の最終シートであるときは、接着部材のシートへの塗布を行うことなく既に接着剤を塗布した位置を押圧部材７１の押圧位置に移動してシートの押圧を行う。【選択図】図２１
