Abstract:
1. A sheet processing apparatus comprising: a first and a second sheet processing portions that perform a sheet process on a sheet or a sheet bundle; a first conveying path which conveys the sheet to the first sheet processing portion; a second conveying path which conveys the sheet to the second sheet processing portion; and a linking path that links the first and the second conveying paths, wherein while the first sheet processing portion performs the sheet process on a preceding sheet or a preceding sheet bundle, a subsequent sheet is conveyed to the second conveying path and held on the second conveying path, the subsequent sheet held on the second conveying path is conveyed to the first sheet processing portion, and if a sheet next to the subsequent sheet is conveyed to the first conveying path, then the subsequent sheet held on the second conveying path is conveyed to the first sheet processing portion via the linking path, superimposed on the sheet next to the subsequent sheet.
