Patent ID: 8814156

Claim:
A sheet processing apparatus comprising: a feed-in path through which a sheet is fed; a first transport path which is connected to a downstream end of the feed-in path and through which a sheet fed from the feed-in path is transported; a first processor that sequentially stacks sheets output from the first transport path and that performs first processing on a bundle of stacked sheets; a second transport path which is connected to the downstream end of the feed-in path and through which a sheet fed from the feed-in path is transported; a second processor that sequentially stacks sheets output from the second transport path and that performs second processing, which is different from the first processing, on a bundle of stacked sheets; and a common retention path that causes a sheet fed through the feed-in path to temporarily remain on the common retention path and that causes the sheet temporarily remaining on the common retention path to be output to one of the first transport path and the second transport path, wherein one end of the common retention path retention is connected to the second path and another end of the common retention path retention is connected to the second path.
