Abstract
A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

An image forming apparatus comprising:
- a printer configured to print on a sheet;
- and
- a sheet processing apparatus connected to the printer, the sheet processing apparatus including:
- a receiving portion configured to receive the printed sheet from the printer,
- a first binding unit configured to bind the sheet received by the receiving portion,
- a discharge tray on which the sheet bound by the first binding unit is stacked,
- a second binding unit configured to bind the sheet received by the receiving portion,
- a pair of folding rollers configured to fold the sheet bound by the second binding unit, the pair of folding rollers being disposed below the first binding unit,
- a conveying unit configured to convey the sheet folded by the pair of folding rollers along a conveyance path,
- a cutting unit configured to cut the folded sheet which has passed through the conveyance path, the cutting unit including a first blade disposed above the pair of folding rollers and a second blade configured to cut the folded sheet with the first blade and disposed above the pair of folding rollers,
- a scrap path through which scrap generated when the sheet is cut by the first and second blades and an air blown from a blowing unit pass, the scrap path being arranged below the first and second blades, and
- a storage unit configured to store the scrap that has passed through the scrap path,
- wherein the discharge tray is disposed between the receiving portion and the cutting unit in a horizontal direction, and
- wherein the discharge tray can be positioned so that a horizontal virtual line intersects the scrap path, the conveyance path and the discharge tray.
