Abstract
The present invention is to enable folding processing to be applied to also large sheet sizes without upsizing the entire apparatus, in the sheet post-processing apparatus for performing the folding processing and binding processing on sheets, a sheet post-processing apparatus is provided with a binding processing section for performing binding processing using a binding needle on a sheet bunch inside a storage section, first folding roller pair for nipping a sheet P inside the storage section in a first position to form a first fold portion, a receiving section for receiving the sheet with the first fold portion formed fed out of the first folding roller pair, and second folding roller pair for nipping the sheet inside the receiving section in a second position to form a second fold portion.
Claims6
A sheet post-processing apparatus comprising:
- a conveying section adapted to convey a sheet in a predetermined conveyance direction;
- a storage section adapted to store sheets conveyed by the conveying section;
- a binding section adapted to apply binding processing using a binding needle to a sheet bunch formed from a plurality of sheets stored in the storage section;
- a needle storage section detachably attached to the binding section to store the binding needle supplied to the binding section;
- a first folding roller pair adapted to nip a sheet or the sheet bunch stored in the storage section in a predetermined first position in the conveyance direction, and thereby form a first fold portion in the first position;
- a receiving section adapted to receive the sheet or the sheet bunch with the first fold portion formed by the first folding roller pair;
- and
- a second folding roller pair adapted to nip the sheet or the sheet bunch with the first fold portion formed inside the receiving section in a second position different from the first position, and thereby form a second fold portion in the second position,
- wherein the first folding roller pair and the second folding roller pair are disposed on a same side as the needle storage section attached to the binding section with respect to the storage section, below the needle storage section, in a thickness direction of the sheet or the sheet bunch stored in the storage section, and
- the receiving section is disposed above the first folding roller pair and the second folding roller pair so as to sandwich the needle storage section between the storage section and the receiving section, in a position crossing a locus of the needle storage section being removed from the binding section to add the binding needle.
