A sheet processing apparatus includes a saddle unit on which a mountain-folded sheet folded along a folding line is accumulated so as to straddle the saddle unit, a staple inserting section disposed above the saddle unit, and a staple receiving section accommodated in the saddle unit. The staple inserting section includes an inserting unit which inserts a staple into the folding lines of the sheets, and holding members disposed on both sides of the inserting unit in a direction parallel to the folding lines of the sheets. The staple receiving section includes a staple receiving unit which receives and bends the tips of the staple inserted by the inserting unit, and supporting members disposed on both sides of the staple receiving unit at positions opposite to the holding members.

The invention relates to a device (1) for the stacking, in packets, of bags produced from plastic film, the device (1) having at least one traction means, preferably a toothed belt (2), and at least one carrier (4), on which the bags can be laid flat on each other and which can be fastened to the traction means for driving, and the at least one carrier (4) having at least one means, in particular one driver element (3), for driving the laid bags, the driver element (3) being arranged on the carrier (4) in such a way that the position of the driver element can be changed.

A stacking apparatus is provided with a stacking member that stacks a sheet as a recording medium that is discharged from a recording apparatus such that the sheet hangs on the stacking member, a guiding part that guides the sheet down to a point lower than a top of the stacking member, and an urging unit that controls movement of the sheet.
