Abstract: A tray assembly for a full color thermal transfer type printer is disclosed. The printing mechanism of the printer including a roller platen moves the sheet of printing paper under printing several times forward and backward to effect a full color printing. The tray assembly comprises a discharge tray at the top, a paper guide formed integrally thereunder, and a manual feed tray detachably attached to the underside of the paper guide. The paper guide form an extension of the return paper passage of the printer into which the sheet of paper enters when it is moved backward. The tray assembly further comprises a pair of plate-shaped adapters detachably attached to the interior sides of the side walls of the manual feed tray; thus, the interior side surfaces of the adapters determine, when attached to the manual feed tray, the lateral position of the sheet of paper fed into the printer from the manual feed tray.

Abstract: An automatic sheet feed alignment system is described for feeding sheets of print media such as paper to print mechanism in alignment with the print mechanism. A single motor drives a main sheet advance roller, and is also coupled to a sheet pick roller through a non-reversing clutch. An idler roller is disposed adjacent the drive roller. To feed a sheet into the print position, the motor drives the main drive roller and sheet pick roller in a sheet advancing direction, until the sheet leading edge is advanced into and past the nip between the main drive and idler rollers. The motor direction is then reversed so that the main roller retracts the sheet. Because the sheet pick roller is not driven in the reverse direction, a buckle is formed in the sheet between the sheet pick roller and the nip, tending to align the leading sheet edge with the nip. The motor direction is then reversed to drive the sheet forward to the print position, its leading edge having been aligned.

Abstract: A tri-directional inverter for use in machines requiring copy sheet inversion for collated copy set output uses four rollers forming three sheet-feeding nips.

The sheets are corrugated by corrugating rollers as they enter a spring loaded inversion channel. The spring and corrugation rollers urge the sheets back out of the inversion channel into engagement with either of the selected other nips formed by the four rollers for feeding back into the machine for further processing.

Abstract: A separation arrangement removes printed products from an arriving imbricated stream of printed products and supplies such to a buffer branch arrangement. The non-removed printed products arrive at a feeder installation from an infeed device where there is first formed an imbricated buffer stack of printed products. The removed printed products are wound for temporary storage at the buffer branch arrangement in an imbricated or shingled formation with a buffer winding band upon a winding core or mandrel to form a buffer package. Upon interruption of the arriving imbricated stream of printed products these printed products stored in the buffer package are unwound and delivered to the infeed device, so that the supply of the imbricated stream of printed products is not interrupted. Since the buffer package possesses an appreciable storage capacity it is also possible to span longer interruptions of the infed imbricated stream of printed products without having to shutdown the feeder installation.

Abstract: A paper feeding apparatus for the printer having an intermittent mechanism between a driving motor and both a paper feed roller and a platen. The intermittent mechanism allows both the platen and the paper feed roller to rotate simultaneously and also allows only the platen to rotate while the paper feed roller is suspended, so that a sheet of printing paper is set straight along the platen. When the rotational direction of the driving motor is reversed to reverse that of the platen, the driving motor stops rotating for a limited period. Under such conditions the sheet is fed properly in response to the rotation of the platen, being free from the inertia force of the sheet and from the platen's vibration.

Preferably, while the guide member is in the first position, a sheet can be conveyed form one part of the second conveyor path to one part of the first conveyor path via a third conveyor path which does not pass through the intersection. Similarly, while the guide member is in the second position, a sheet can also be conveyed from one part of the first conveyor path to one part of the second conveyor path via the third conveyor path.

Abstract: An automatic document transportation device has a rotatably supported guide piece at the junction between a document feeding route through which an incoming document sheet to be processed is passed to a scanning position and a discharge route through which the processed document sheet, moving backwards from the scanning position, travels to be discharged. The guide piece normally assumes a downward position by its own weight, thereby blocking the feeding route in such a way that the incoming document sheet can cause it to rotate and travel past it but the outgoing sheet, moving in the opposite direction, is deflected by it into the discharge route.

Abstract: Continuously conveyed flexible flat structures, especially printed products, infed in an imbricated formation, are turned such as to retain their original imbricated product formation. This is accomplished by accelerating the flexible flat structures such that they are singled and then in such singled condition are deflected about a deflection axis directed transverse to the product infeed conveying direction. Thereafter the singled turned flat structures are decelerated and transported away in an opposite conveying direction.

This traction element has mutually spaced outwardly extending carrier or support elements, at the outer ends of which there are mounted controlled grippers for engaging a respective one of the flat structures.

Abstract: An automatic document feeder in an electrophotographic copying machine for making copies of both sides of a document comprises a passageway for a document to pass through, a driving roller adapted to rotate in both normal and reverse directions and a rotatable drum. A document which has been fed is transported through the passageway by the roller rotating in the normal direction and is wrapped around the drum to reach a scanning position. After the scanning for copying operation, the document is led into the same passageway by revese rotation of the driving roller but the document is then in an upside down position such that when the roller is operated in the normal direction again, the document is wrapped around the drum with its backside exposed to the scanning light. Thus, both sides of a document can be scanned automatically.
