The apparatus for carrying out the method comprises a plurality of delivery trays arranged in the manner of a circulating bucket lift, which on the basis of user inputs can be freely selected and transported to a loading plane in which an inlet opening for the copy or print jobs also is located. An outlet opening is provided opposite the inlet opening, the individual delivery trays can be moved around a passthrough region which joins the inlet opening to the outlet opening, and each of the delivery trays can, in order to receive copy or print jobs, be slid into a loading position in the passthrough region and receives the copy or print job intended for that selected delivery tray.

Method and apparatus for collecting and transporting copy or print jobs

Apparatus for stacking sheets comprises a collecting bin with a front stationary abutment and a rear limiting element adjustable to various sheet size ranges. A first deflecting roller, adjustable in the entrance direction of the sheets and mounted on a rear limiting element, provides support for a transport belt transporting the sheets. The rear limiting element is mounted on a support which is movable in the entrance direction by means of two parallel threaded spindles rotatable by a stepping motor. A second deflecting roller which is associated with the outer side of the transport belt facing the sheet stack is arranged on the support, whereas the first deflecting roller is located on the inner side of the transport belt. Adjacent to the second deflecting roller, a stationary deflecting roller is arranged such that the transport belt is guided along an S-shaped path. When the support is adjusted in the entrance direction, the first and second deflecting rollers are moved by equal distances so that the guide length of the transport belt remains constant at all times.

Apparatus for stacking sheets

A collecting bin for stacking sheets fed seriatem thereto, including an abutment associated with the front edges of the sheets in the area where a stapling device and a sheet-stack removal device are arranged. Above a sheet stack in the collecting bin and upstream of the stapling device, a rotatable shaft is mounted transversely to the sheet-feeding direction and parallel with the upper side of the sheet stack. The shaft is driven by a stepping motor in either direction of rotation. Separating fingers, arranged on the shaft, are selectively lowered onto the sheet stack by shaft rotation to form an inclined feeding surface for subsequently entering sheets, separating such subsequently fed sheets from the sheet stack beneath. When the sheet stack has been removed from the collecting bin, the shaft rotates in the opposite direction in order for separating fingers to deposit the separated sheets in the collecting bin. After the sheets have been deposited, the rotation of the shaft moves the separating fingers until they assume an initial position above the sheet stack.

A sheet feeder includes a supply tray from which the paper sheets are individually withdrawn from the bottom of the stack. The stack supporting bottom of the tray is inclined relative to a horizontal plane, its angle of inclination being adjustable. The inclination of a supported stack can be adjusted according to stack weight or height. The weight of the sheet stack exerting pressure on stack support and/or the sheet separating device can thereby be controlled such that uniform sheet removal conditions are achieved.

In a supply magazine of a copying machine closed copy paper packages are arranged in stacked relation. The copy paper has been preconditioned by the manufacturer and provided with a packing that protects the preconditioning. Whenever the copy paper supply for the copying machine has to be refilled, one copy paper package is removed from the supply magazine and advanced to an unpacking device and opened. The unpacked copy paper stack is withdrawn from the opened packing by a withdrawing device and moved to a magazine. The magazine is associated with a sheet separating device which removes individual sheets and advances them to the copying station.
