Abstract:
1. A sheet processing apparatus for processing a plurality of sheets as a bundle comprising: a sheet bundle thickness-detecting sensor that detects a thickness of the bundle of sheets; a sheet counter that counts a number of sheets processed as a bundle; a sheet thickness-calculating device that calculates a thickness of each sheet based on the thickness of the bundle of sheets detected by said sheet bundle thickness-detecting sensor and the number of sheets counted by said sheet counter; a sheet thickness information storage section that stores per-sheet thickness information indicative of the thickness of each sheet and a bundle upper limit indicative of a number of sheets that can be processed as the bundle for each sheet; and a rewriting device that rewrites the per-sheet thickness information and the bundle upper limit stored in said sheet thickness information storage section, according to the thickness of each sheet calculated by said sheet thickness-calculating device.
