Abstract
A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.
Claims17
A sheet stacking apparatus comprising:
- a frame;
- a round member directly or indirectly connected to the frame;
- an arm directly or indirectly connected to the frame;
- and
- a processor directly or indirectly connected to the arm
- wherein the arm is rotatable between a first position and a second position,
- wherein the arm is adapted to be positioned to bias a second type of sheets toward the round member when in the first position,
- wherein the arm is adapted to be positioned to bias a first type of sheets away from the round member when in the second position, and
- wherein the processor is adapted to position the arm in the second position for a trailing edge of the first type of sheets and to position the arm in the first position for a trailing edge of the second type of sheets.

A sheet stacking apparatus comprising:
- a frame;
- a round member directly or indirectly connected to the frame;
- a first arm directly or indirectly connected to the frame;
- a second arm directly or indirectly connected to the frame;
- and
- a processor directly or indirectly connected to the first arm and the second arm
- wherein the first arm is rotatable between a first position and a second position,
- wherein the second arm is rotatable between a third position and a fourth position,
- wherein the first arm is adapted to be positioned to bias a second type of sheets toward the round member when in the first position,
- wherein the first arm is adapted to be positioned to bias a first type of sheets away from the round member when in the second position,
- wherein the second arm is positioned to bias the first type of sheets and the second type of sheets toward the round member when in the third position,
- wherein the second arm is positioned to not bias the first type of sheets when in the fourth position, and
- wherein the processor is adapted to:
- position the first arm in the second position for a trailing edge of the first type of sheets;
- position the first arm in the first position for a trailing edge of the second type of sheets;
- and
- position the second arm in the fourth position for the trailing edge of the first type of sheets and the trailing edge of the second type of sheets.

A sheet stacking method comprising:
- rotating a round member to move sheets to a stacking surface;
- and
- rotating an arm to rotate the arm between a first position and a second position relative to the round member,
- wherein the arm is adapted to be positioned to bias a second type of sheets toward the round member when in the first position,
- wherein the arm is adapted to be positioned to bias a first type of sheets away from the round member when in the second position, and
- wherein the rotating of the arm controls the arm to only rotate to the second position for the first type of sheets and to maintain the arm in the first position for the second type of sheets.
