Abstract: A paper pick-up unit of an image forming apparatus includes an elliptical pick-up rubber having a first arcuate part and a second arcuate part. The first and second arcuate parts are symmetrical to each other and contact a paper. A pick-up housing supports the pick-up rubber, which are attached around the circumference thereof. A first shaft opening and a second shaft opening are formed opposite to each other in the pick-up housing and are eccentrically disposed with respect to a center of the pick-up housing. A pick-up shaft is engaged with one of the first shaft opening and the second shaft opening of the pick-up housing, and is capable of rotating. The pick-up shaft is engaged with the first shaft opening of the pick-up housing for the first arcuate part of the pick-up rubber to pick up a paper. The pick-up shaft is engaged with the second shaft opening of the pick-up housing for the second arcuate part of the pick-up rubber to pick up a paper.

Abstract: An image processing apparatus ejects the sheet to witch image processing unit perform to an ejection tray or a staple stacker by a pair of ejection rollers and the like. A sheet path for guiding the sheet to the ejection rollers is opened and closed in conjunction with slide movement of the ejection tray when the ejection tray is attached to a main body of the apparatus, and the sheet path is opened and closed in conjunction with the slide movement of a staple stacker when the staple stacker is attached to the main body of the apparatus.

Abstract: An apparatus and method to decelerate printed product in a stacking process is provided. The printed product may be a product such as printed paper, foil, or plastic. A continuous web of product may be cut into single items, one item at a time, and then the items may be stacked on top of one another. The apparatus may be comprised of a cylinder, which is comprised of a vacuum chamber having perforations and a blowing chamber having perforations. A first slow delivery tape, and first and second fast delivery tapes may also be provided. Each of the delivery tapes may have perforations to allow air to pass through and from or to the cylinder. The first slow delivery tape is wrapped around the cylinder. The first and second fast delivery tapes are wrapped around rollers and may help to create separation between individual cut items and may control moving items. The first slow delivery tape may slow down items to allow stacking of items.
