Error display ^ i

The innovation relates to error display warnings, such as those used in the case of tax returns ^, and in particular to defective devices for displaying the incorrect feeding of pen pins with a feed bed , length to which the shafts are fed, and a component pivotably arranged in the vicinity of the feed beds, which is detected when documents pass along the feed path in order to achieve a faulty line about the pivot axis d ^ ehb ^ r.

In such Fehleranzei ^ eeinrichtuns according to the Reuerun "vorfesch]. Q ~ pp., F5 ^a ß cia ^ pivotally mounted member is offset from the feed bed by a distance which is animal greater than the thickness of a single document in extracts, and DAP the component has a surface with which

Acted according to a special embodiment of the innovation the pivotably arranged component is a screen or a shutter, to interrupt a light beam to the "error display ^ u.

Another embodiment of the innovation is the component pine marking device, which by rotating the component for Yarkierunp of overloaded documents is operated. Preferably is the marking that the marking device quf the • Applies ^ ν, -ηί-Pt pieces, erasable.

In FIGS. 1 and 2, a document feed bed 1 is made up of feed rollers 3 on which are offset from one another in the longitudinal direction of the bed. Document feeders 4 Mnd parallel to the surface of the feed bed 1 and in section 3 provided by this. A support arm 5 on one side

of the feed bed 1 is mounted, a plate 6 receives vertically above the feed bed 1. A valve disposed at a distance pair of Seitenwan ^ s 7 is supported by the ^p £ latte, the Wansen are retained by three pins 8, 9, 10 spaced from each other, which are befestirt at their opposite ends to the cheeks. The cheeks take a pivot pin 11 between them. A component 12 is arranged rotatably about the pin 11 and lies in the vertical direction between the side walls 7. The component 12 is pretensioned by a tension spring in a clockwise deflating direction, as shown in FIG. 2, the spring between pin 8 and a further pin 14, which is received by component 12, is effective. The movement of the component 12 in the counterclockwise direction is limited by the pin 10. The surface 15 of the component 12 near the feed bed 1 has such a profile that the gap between the surface 15 and the feed bed 1 is kept at a largely constant dimension during the displacement of the component 1 / around the pivot pin 11.

The component 12 also receives a marking device, which from a soft pen 16 which is held in a jig 17. The jig 17 is taken up by a hole in front of component 12 and is spring-loaded by a compression spring 18. Dependent on the movement of the component 12 in a clockwise direction directs the pen 16 towards the feeder 1.

The component 12 also has an extension 19, which by "movement of the component 12 clockwise between a photoelectric Cell 20, which is housed in a block 21 of one of the cheeks 7, and a lamp 22, which is in one on the plate 6 attached lamp housing 23 is housed is inserted.

In operation, the space between the lower surface 15 of the component 12 \ ind the upper surface of the feed bed 1 becomes corresponding the thickness of the documents along the feed bed 1

are set. The space between these surfaces is preferably one and a half times the thickness of a single one Document, however, this distance is not critical and the limit values] ieeen so that the space is greater than the thickness of a document, but smaller than the thickness of two documents should be.

The documents are normally advanced from the right to the left in the drawing ISn ^ p of the feed bed 1 over the feed rollers 3. It is known to feed the documents along a feed bed; this ^Zv: eck the lower feed rollers are rotated in Gesenuhrzeicerrichtung 3, while the upper feed rollers 3 circulate in Uhrzeiperrichtunf, and it will ° advanced in the document in that it longitudinally from the access of a pair of feed rollers 3 in the access of the next pair of Zufü ^v rbettes 1 passes.

Since the gap between the surface 15 and the top of the * Feed bed 1 is larger than the thickness of a document, the documents can move freely through the gap, while continuously feeding them one by one. Tm case Eires occurring during feeding error, for example such that two documents are fed overlapping, arises At a certain point of the feeding process at the gap, a V thickening that is twice the thickness of the document. After the Sr> old is smaller than this doOplte thickness, the Top of the upper document together with the cam surface 15, and when the feed rollers continue to feed the documents, causes friction between the upper document and the surface 15 that the component 12 rotates clockwise will.

In this position, the extension 19 of the component 12 is inserted between the lamp 22 and the photoelectric cell 20. The photoelectric cell is connected to the control circuit of the document processing apparatus, of which the display device described here is a component. For example, the display device can represent part of an index card reader that is assigned to a computer

is. In this case, the Ohotoelektrische cell may, for example, in a control circuit SAEN arranged that a Anzeigesif is obtained "nal, which is given to the operation of d ° p K ^ r ^ fr ¹ esprs to <=> - nerren and ^ leirhzeiti" the to indicate to the computer operator that he must attend to the card reader.

Moving the component 12 clockwise also brings the pen 16 into contact with the topmost document. The pen 16 protrudes from the component to such an extent that it touches the document before moving. clockwise, and that ^{the pen 1} * 18 allows the pen 16 to be withdrawn into the end of the component 12 "when it touches the document. The movement of the document occurs when the ^c ~ hreibstift 16 dn? touching document, a line on the document. Instead of a pen can ht a.ch ei ^r felt or ^ p ^<= erdo "which is betränkt with marking paint, are used so that the mark on the document are aufpebraeht canr. Preferably, however, a recognizable marking is applied to identify the document, since this marking is only used to identify incorrectly supplied documents; If documents are passed through the device more often, permanent or permanent marking can lead to inaccurate marking and this can lead to a misdirection later.

To avoid damage to overlapping documents or to avoid successive documents, ie stack behind those in a different way, ve! before flawed have been supplied, is it desirable that? the display device is resiliently attached, so that it is yielding works and enables incorrectly managed documents to pass through, instead of capturing the documents that have been exposed in such a way that they are blocked. In the case of this Device, the support arm 5 is designed so that he can only bend slightly so that the documents can pass the component 12 after it has been turned clockwise to the full

For example can the <? entire facility on a spring-loaded Be arranged support arm. In this case, the spring preload of the support arm must be based on the relative stiffness of the documents to be introduced and related to the biasing spring 13.

On the other hand, the component 12 can be attached resiliently. For this purpose, the component 12 can either accommodate a resiliently designed socket in which a laser for ^ s rotary pin 11 is attached, or the I? <? Er for the pin 11 in the side lugs 7 can yield in a similar manner Sockets to be attached.

passed along. With this arrangement, the top card 24 in the feed bin 25 is always the card that will be fed closest. If an incorrect feed occurs, for example two cards ?. \ Are fed in with one another, the top card is earlier in the sequence. The effect of the marking device, such as, for example, the pen 16, is to mark the earliest card 24 in the sequence at the point at which a faulty feed occurs. By checking the documents and reading out the marked card, the operator can then easily determine which cards have to be read out again, since the marked card is the first of these cards.

The display device described above gives an indication of that a misfeed of documents in an overlap has occurred and that it is necessary that the Just watch out for the feed of pieces. At the same time »marked the device also includes incorrectly supplied documents, <= c that a simple identification of such errors fübrter documents is possible.
