摘要

This invention has as its object to provide a sorter apparatus which allows to easily identify bundles of sheets in units of jobs. After the end of each job operation, if a bundle of sheets of the preceding job remain on the sorter, a message for removing sheets is displayed, and the control waits until the sheets are removed. When no bundle of sheets of the preceding job remain or when the bundle of sheets of the preceding job are removed, a bundle of sheets of the current job are pushed and shifted, and execution of the next job is permitted. With this control, a step can be formed between bundles of sheets in units of jobs, and the bundles of sheets in units of jobs can be easily sorted.
