Abstract
A finisher unit receives a sheet discharged from a copying machine, and in a folding/punching mode, the sheet is conducted into a longitudinal transport path. A fold/punch mechanism includes a pair of folding rollers and a punching rod. The sheet fed into the longitudinal transport path goes in contact, at its leading edge, with a nip portion between transport rollers which are in the state of rotation stop, whereupon a center portion of the sheet is bent to be threaded between the folding rollers and transported to the punching rod. When the bent portion of the sheet is transported by a given distance, the punching rod operates one vertical stroke to provide a punch hole to the sheet.
