Description

The invention relates to a device for improving the guidance, in particular overlong, in particular in relation to their length, narrow printing materials, which may consist of artificial, natural or metallic materials, at the entrance of laser or LED printers. On the compliance with a lateral guidance accuracy, it is important if on pre-printed media in a further necessary printer pass additional effects such. B. shadow frames to an existing typeface and / or additionally imprinted pictorial representations or for writing further pictorial representations are to be attached. The aforementioned pre-printed printing materials are in particular equipped with metallic stamping foils, which must be repeatedly subjected to a printer pass due to the impossibility of a continuous printing process in a color laser printer or color LED printer.

Adjusting devices or support devices for the use according to the invention are not known from the prior art. In addition to the usual paper trays for standardized paper formats, which are closed or open to printers, plotters, etc., there is also the ability to attach a defined large adjustment device for a sheet guide in front of the printer, as it DE 38 360 23 C2 will be shown.

The adjustment device has in its housing a pair of reciprocable sliding members having guides engageable on opposite edges of the respective blade. The guides or sliding elements are movable relative to the housing via an operating device, the sliding elements showing toothed rack sections engaging in the pinions of the drive. Drive device and sliding elements can be determined alternately or put into action d. h., be operated.

The weak point of this proposed solution is that due to the game in the rack sections repeated insertion with a precisely scheduled coverage z. B. existing on a print medium existing font or visual representation not succeed and thus framing / silhouettes are not possible to this.

This disadvantage has to be overcome if, as in the case of printing with metallic stamping foils, it is a question of combining further effects in a second or further printing pass with the already existing pressure.

It is therefore an object of the invention to propose a solution in which prior to entry into a printer a print medium physically supporting platform can be attached, especially for repeated printing of a pre-printed print medium, which is narrow in relation to its length, exactly fixable lateral Has guide elements that can be immovably fixed for repeated printing passes, so that connection prints can be made without offset.

The object of the invention is achieved as follows, reference being made to the protection claim 1 with regard to the fundamental inventive idea. The further embodiment of the invention results from the protection claims 2 to 5.

Further instructions for explaining the invention are required.

The device initially consists of a flat base plate, which represents as it were the printer table, which - due to its length - has paired support legs that place him in a horizontal position to the printer inlet. In alignment with the narrow parallel sides of the printing table are located on its upper side, which serves as a work surface defined aufeinanderzu- and wegbewegliche - rectangular in cross-section - guide elements, which are in operative connection to sliding blocks under the printer table. This is achieved by the sliding blocks are provided with a narrow web and, passing through a slot located in the printer table or a slot, firmly attached to the underside of the respective guide element. The introduction of the slots in the printer table, which are arranged there at an angle of 90 ° to the respective guide element, is selected by their number so that according to the length of the printer table, a distance between them of about 150 mm can be maintained. The elongated holes of the left and right guide element are arranged in the printer table either at the same height or slightly offset from each other. So that the guide elements travel together in their lateral mobility the same way, located on the outsides of each slot pair under the printer table each have a free-running pulley, which communicate with each other by means of a flexible, narrow sheet metal strip. On the narrow, flexible sheet metal strips, the sliding blocks are firmly attached, which can travel within the slots in operative connection with the aforementioned web and the left and right guide element, a predetermined distance. Since the deflection strip connecting the metal strip has a non-changing bias, occurs in any of the Gleitsteinpaarungen a game and it can be As a result, guide elements ultimately do not tilt laterally.

It is conceivable that, instead of only sliding block pairings in the manner proposed according to the invention, alternating dovetail-shaped sliding guides may also be provided in addition to the sliding block pairings.

Likewise complicated to produce and serviceable gear / rack gear pairings are conceivable that allow the lateral mobility of the guide elements.

Although the metal strip connecting the sliding blocks produces sufficient self-locking, it may be advantageous for a self-locking reinforcing tension spring to be integrated within the metal strip.

Furthermore, it can be provided that in addition to the stepless mobility of the parallel located on the printer table guide elements, their defined possible path of the shift can be divided by exactly approachable detent points.

It is also conceivable a scale graduation on the printer table for fast and precise alignment of the guide elements in a run.

The invention will be explained in more detail with reference to an embodiment. For this is on the representations in the 1 to 5 resorted.

The device consists of a work surface that covers the printer table 1 represents, which front on support feet 10 (not shown in detail) is supported and the pressure side, by conventional coupling elements, temporarily fixed before the printer inlet is positioned. Over the entire length of the printer table 1 extend from the respective edge to the center thereof parallel to each other and away from each other movable guide elements 2 , which are designed as rectangular solid or hollow profiles. At a defined distance are in the printer table in pairs opposite and slightly offset from each other arranged slots 3 respectively. 4 that has a firm connection between the bottom of each guide element 2 and one under the printer table 1 located sliding block 7 over a footbridge 6 (not shown in detail). This is the lateral mobility of the guide elements 2 given in principle. However, in order that the simultaneous movement of the same distance along the same path is made possible according to the invention, it is located under the printer table 1 outside at each slot 3 respectively. 4 a free-running pulley 5 , In this sense, in each case in pairs opposite pulleys 5 by means of a taut, narrow and flexible metal strip 8th interact with each other. At this closed strand is each per slot 3 respectively. 4 a sliding block 7 firmly attached, over the jetty 6 in firm connection with the underside of a guide element 2 stands. As a result, it is advantageously possible that in each case the left and right guide element 2 on the printer table 1 exactly parallel to each other and for the same distance, can be set precise guidance and persist according to the principle of self-locking at the set location.
