Definitions
- the invention relates to a document processing device, in particular a document printer with a document output section, which has a slit-shaped document output opening and a document table downstream of this in the document output direction.
- Document processing devices of the type mentioned are, for example, document reading or printing devices.
- a receipt is carried past the processing station by means of transport. He will e.g. held securely between pairs of rollers.
- the document is pushed by the transport device out of the delivery opening onto the document table, where it can be removed manually by the operator.
- the documents are conveyed at high speed. This gives them such an impulse when they leave the transport device that they shoot far out of the dispensing opening. Long documents in particular then tend to fall off the document table because their center of gravity comes to lie in front of the housing edge.
- This object is achieved in that on the document table, parallel to the document delivery opening, there is an area which is slip-resistant and which projects beyond the document table surface.
- the invention is based on the observation that printed receipts slide on an air cushion over the service table, so that their coefficient of friction with respect to the table surface is low. The application of a slide escapement on the table surface would not change that. Only an increase in the smooth table surface interrupts the load-bearing air layer and the slip lands on the former, so that a slip inhibition on the table can be effective. A particularly good braking effect is achieved if the area overhanging the table surface has a non-slip surface. This area should have the same coefficient of friction everywhere and be parallel to the document delivery opening, ie also parallel to the leading document edge, in order to avoid tilting of the document.
- the anti-slip area projecting above the document table expediently has its width. With this, documents of any width can be processed. If documents of only one width or less different widths are to be processed, circular increases, so-called humps, are sufficient close to the edges of the receipts. Areas in between then have the low coefficient of friction, which further facilitates the supply of documents.
- the raised area can be formed in one piece with the service table: in the case of a table formed from a plate, by embossing a bead or trough from the underside, in the case of a plastic injection-molded part, by appropriate shaping of the injection mold.
- the anti-slip effect can be achieved by roughening or by coating with a granular material or a plastic with a high coefficient of friction.
- the raised area can also be formed by a profile strip made of rubber or plastic, which is inserted into a groove in the side table or glued to it.
- the profile strip is advantageously in the region of a recess set back to the table surface by a small amount — preferably 0.5-3 mm — which accommodates the edge of the profile strip near the dispensing opening. This prevents a document from hitting the lower edge of the profile bar.
- the upper edge of the front wall of the lower housing part forms part of the supply table.
- the recess in this arrangement is formed in that the upper edge of the front wall springs back by the aforementioned small amount relative to the table surface. No additional work step is then required to produce the return.
- the upper housing edge is set back so far relative to the surface of the table that the profile strip does not protrude from the latter.
- a document is only braked when it has so far over the table surface that it is bends down and touches the profile bar. With this arrangement, the document is fed in without any hindrance to the operator.
- 1 is a sectional side view of a receipt printer with a first embodiment of the profile strip
- Fig. 2 shows a detail from Fig. 1 with a second embodiment of the profile bar
- FIG. 3 shows a cross section through the profile strip according to FIG. 2
- Fig. 1 is a receipt printer designated 10. It has an upper housing part 12 and a lower housing part 14.
- the upper housing part 12 leaves the front area of the lower housing part 14 free, which is closed at the top by a loading table 16.
- the document table 16 is laterally delimited by a document system 18 which ensures a defined lateral position of the documents 20, 20 '.
- a guide plate 22 is arranged at a short distance from and parallel to the service table 16.
- the loading table 16 and the baffle 22 form a loading transport shaft 24.
- the front end 26 of the baffle 22 is bent away from the loading table 16 by approximately 45 °, so that it forms a funnel-shaped narrowing input / output opening 28.
- a pair of transport rollers 30, 32 is arranged in the transport shaft 24 in the document input direction E directly behind the funnel. Behind it is a printing station 34, which is formed in a known manner from a needle print head 36 and a platen 38 and is therefore not described in detail.
- the front wall 40 of the lower housing part 14 has an area 44 of greater wall thickness near its upper edge 42.
- the edge 42 is set back from the surface 46 of the document table 16 by a dimension d1.
- an upwardly open groove 48 is incorporated, into which a profile strip 50 with an oval cross-sectional profile is inserted.
- the part of the profile strip 50 lying outside the groove 48 projects beyond the upper edge 42 by the dimension d1, that is to say is approximately flush with the surface of the service table 46.
- a document 20 to be processed is pushed manually by the operator in the direction of arrow E over the document table 16 into the input / output opening 28 until it abuts the pair of rollers 30, 32. Then a drive motor (not shown) is switched on, which rotates the transport rollers 30, 32 in the sense of document receipt, whereby the document is conveyed into the printing station 34. After printing, the transport rollers are driven in the ejection direction at high speed. The document is catapulted out of the pair of transport rollers 30, 32 and flies on an air cushion over the document table 16 against the direction of the arrow E. A short document looses speed so quickly that it still lies safely on the document table is coming.
- a long document on the other hand, has already left the document table with its leading edge when its rear edge leaves the pair of transport rollers 30, 32. Its own weight causes it to bend downwards, as is shown for document 20. there he comes into contact with the profile strip 50, which brakes him to a standstill so quickly that his rear edge can still be supported on the guide plate 22. This effectively prevents the document 20 from falling off the document table 16. An unbraked document would tip over the housing edge 42 and fall off the document table 16. This is shown schematically for a document 20 'shown in dash-dotted lines.
- FIG. 2 shows the parts of a second exemplary embodiment of a receipt printer 110 relevant to the invention in a sectional side view. The following are shown: part of a loading table 116, part of a lower housing part 114 with front wall 140, which has an area 144 of greater wall thickness near its upper edge 142, into which a groove 148 which is open at the top is incorporated. A profile strip 150 is inserted into this.
- the upper edge 142 jumps back by a dimension d2 relative to the surface 146 of the document table 116.
- the part of the profile strip 150 protruding from the groove 148 jumps back by a dimension d3 with respect to the surface of the service table 146.
- the leading edge of a document ejected by the transport rollers 30, 32 must first be conveyed beyond the edge of the upper edge 142 by an amount determined by the physical properties of the document, so that it can tilt downwards so far that the document is braked by the profile bar 150.
- This arrangement has the advantage when inserting a document in the document printer 110 that the profile bar 150 is not touched, so that its braking effect does not come into play.
- FIG. 3 shows the cross-sectional profile of the profile strip 150 in the installation position shown in FIG. 2 in the receipt printer 110
- Profile strip essentially consists of a mushroom-shaped upper part 152, which projects beyond the groove 148, and a fastening web 154 which engages in the groove.
- the underside of the upper part 152 forms a support surface 156 which, when the profile strip is installed, lies tightly on the upper edge 142 of the front wall 140 of the housing.
- the flank 158 of the upper part 152 facing the input / output opening 28 (FIG. 1) rises at a flat angle relative to the upper edge 142 in order to ensure that a slip slides easily onto the profile strip 150.
- the flank 160 of the upper part 152 facing away from the input / output opening has the shape of a circular arc, the radius of which is adapted to the edge radii selected on the printer housing for design and demolding reasons.
- the fastening web 154 tapers to a point at its lower end 162 and is provided with spreading webs 164 pointing obliquely away from the tip on both sides near the lower end. Over these, frankings 166 are provided in the fastening web 154.
- the profile strip 150 When inserting, the profile strip 150 is simply to be inserted into the groove 148 (FIG. 2) with its pointed end 162.
- the expansion webs 164 slightly deflect in the direction of the clearances 166 when pressed into the groove 148.
- the profile strip is pressed into the groove 148 until its support surface 156 rests on the upper edge 142 of the housing wall 140.
- Natural rubber with a hardness of approx. 45 Shore A has proven to be particularly suitable as the material for the profile strip, because this material has a high coefficient of friction and the profile strip can be easily inserted into the groove with this hardness, but on the other hand it stays securely in it.
