Abstract
A collection vessel 124 has a shutter 138 for opening and closing collection ports 136. A rotation shaft 140 of the shutter 138 is provided with an opening/closing piece 144. The opening/closing piece 144 abuts a protrusion on an image formation apparatus main unit and opens the shutter 138 largely so that a discharge section inserted into the collection port 136 does not abut. The collection port 136 is made a long hole so as to allow the discharge section to move. Further, the shutter 138 is formed integrally with a plurality of door parts 142 so as to open or close the collection ports 136 by one operation.
