Abstract: A system for improving stacking of flat items stacked on edge and forming a batch of items in a sort bin (200a) of the type comprising a stacking deck (210) for supporting the batch of items, a paddle (220) movably connected to a shaft (224) mounted on the stacking deck for registering the batch of items while applying a first stacking pressure to the batch of items, a driving device (228) for applying at least another adjustable pressure to the batch of items for refining their registering against the paddle, and a movement control module (229) for controlling the driving device so as to adjust pressure in the batch of items, wherein the batch of items and the paddle are driven synchronously and separately.

Abstract: Flat item feeding apparatus (10) having a delivering section (12) for receiving a large batch of flat items on a transport surface (24, 26a, 26b) and a singulating section (14) for extracting these items one by one and transferring them downstream. The delivering section includes a transport device (22) for conveying the stacked on edge flat items towards the singulating section, a pushing device (30) for jogging the stacked on edge flat items during the conveying. The transport device has an endless belt (26a, 26b) protruding a transport deck (24) within a conveying zone B of length d of the delivering section and located a distance d2 from a downstream pulley (29a, 29b) and a distance d1 from an upstream pulley (27a, 27b), the distances d1 and d2 respectively defining determined conveying zone A, C in which the at least one endless belt remains below the transport deck.

Abstract: An ink jet color printer (10) comprises a printer body (15) having a casing with a rear wall (17) provided with a slot (13) in which an interchangeable, disposable type paper cassette (18) containing printing media with given common characteristics is removably inserted; the paper cassette bears are at least 5-bit binary (19) indicating the characteristics of the printing media it contains inside and which is read by the electronic controller (21) of the printer so as to automatically select the optimum printing mode in relation to the specific characteristics of the printing media, thus avoiding mistakes on the part of the user.

Abstract: A device 100 for the feeding of sheets 14 from a ream 18, with a main rotating, feeding roller 27; a tray 13 containing the ream 18; and an auxiliary roller 130 arranged adjacent to the feeding roller 27, wherein the tray 13 is suitable for moving cyclically to bring the ream 18 into contact with the feeding roller 27, so that the latter picks one at a time the sheets 14 from the ream 18 and feeds them along a path 131; and wherein the auxiliary roller 130 is adapted for rotating in contact with the sheets 14 picked by the feeding roller 27, but without pulling them and in the direction opposite their feeding direction, the object being that of opposing the picking of double sheets from the ream 18.

Abstract: An ink jet printer having selectively two distinct working positions (P1, P2), respectively a vertical working position (P1) and a horizontal working position (P2), comprising an external casing provided with a first and a second side, both flat, with a common edge and reciprocally inclined at an obtuse angle; a feeding tray for accommodating at the entrance the sheets to be fed to the printer; and a collecting tray, arranged to the front of the feeding tray, for collecting the sheets at the outlet after they have been printed. In the vertical working position (P1), the printer sits on a horizontal plane on its first side, and has the feeding and collecting trays directed upwardly; whereas, in the horizontal working position (P2), the printer sits on the horizontal plane on its second side, and has the feeding and collecting trays disposed horizontally to the operator.

Abstract: The document aligning and feeding device comprises couples of rollers formed by a delivery roller (15) and a backup counter-roller (14), wherein each couple of rollers is subjected to a lower load during the aligning step and a higher load during the successive feeding step. The backup counter-roller is formed by two separate, coaxially coupling counter-rollers, one of which (33) has a lower coefficient of friction with the document and is the one operating during the aligning step, whereas the other (31) has a higher coefficient of friction and is operational during the successive feeding step. This allows the document to rotate freely about one of its corners during the aligning step, and to advance without being deflected during the successive feeding step.

Abstract: An impact printer (30) comprises a printhead (31) traversing along a guide for printing a line on a document (32) of thickness S, and is provided with contrast means for supporting the document (32) against the head (31) and for contrasting the impact force exerted by the latter against the document. The printhead (31) bears a spacing roller (34) which causes the contrast means to yield in order to compensate for thickness S, which varies according to the document (32), and thus maintain the distance D between the head (31) and the document (32) constant. The contrast means comprise a flexible platen (33) attached yieldingly at the ends, of length at least equal to or greater than that of the print line and having a variable section frame so that the pressure generated between the platen (33) and the roller (34) is substantially constant all along the print line.
