ABSTRACT:
A finisher with a folding section for creasing or folding incoming sheets decides folding positions of the sheets based on contact between the leading ends of the sheets and first folding stoppers as leading-end regulating devices. The finisher adjusts the folding positions with a view to conforming to the sheet sizes and folding modes corresponding to the sheet sizes by means of stepping motor which rotates cam shafts, which is located below the first folding stopper and to which cams are fixed at different angles, and causes the first folding stoppers to alternately move into relevant conveying paths in turn. Accordingly, the finisher obtains the regulating position with high accuracy by the use of a lone drive unit even when the number of regulating positions is set to be large, and includes a compact and inexpensive mechanism which adjusts the regulating positions.
