摘要： A device for folding sheets of a medium into a booklet is provided. The device includes a frame; a cam mechanism attached to the frame; a lever attached to the frame, the lever being actuated by the cam mechanism; a first scissor arm attached to the frame, the first scissor arm being actuated by the lever; a pair of first rolls, one of the first rolls being movable by the first scissor arm; a second scissor arm attached to the frame, the second scissor arm being actuated by the lever; a pair of second rolls, one of the second rolls being movable by the second scissor arm; a crease blade for contacting the sheets to create a crease in the sheets; and a controller that controls a position of the crease blade, a gap between the pair of first rolls, and a gap between the pair of second rolls. The rotation of the cam mechanism through a first period of rotation causes the crease blade to move in a contact direction to create the crease in the sheets by pushing the sheets between the first rolls, the rotation of the cam mechanism through a second period of rotation causes the crease blade to move in a retracting direction away from the sheets, the gap between the pair of first rolls is controlled by the controller based on a total thickness of the sheets to be folded, and the position of the crease blade is controlled by the controller based on the total thickness of the sheets to be folded.
