Finisher with a large-capacity sheet stack section

摘要

A staple sorter which distributes sheets ejected from a copying machine into a plurality of bins and staples stacks of sheets in the bins by use of a staple unit. The bins are vertically movable pitch by pitch, and a large-capacity tray is provided above the bins. A sheet conveyer gate which has rollers, is vertically movable between the bins and the tray. When the sheet conveyer gate is in a lowered position, the rollers take a stapled stack of sheets out of a bin. Then, the sheet conveyer gate is raised and takes the stack of sheets into the large-capacity tray.
