Abstract

A self service printer is improved by providing for temporary storage of several printed documents to be issued as a bundle. An opening in the housing for the printer is normally closed by a pivotable cover behind which documents are accumulated and stored, a first set of transport rollers including drive and pressure rollers is arranged behind the cover and being provided for cumulatively holding and moving one or more individual documents; second set of transport rollers is disposed upstream from the first set of rollers and operated in opposition such that the first set provides for holding or transport and the second set is open and vice versa; a control device operates the cover and said transport roller sets and provides (i) a closed disposition of said cover in an open position for said first set of rollers permitting insertion of documents in between through the second set, (ii) a closed disposition for the cover as well as closed disposition of the first transport roller set for holding and storing documents in between, and (iii) providing issuance of the documents for open cover and closed first set of transport rollers, said transport rollers then being driven; the second set is open during (ii) and (iii).

Description

In Banken und ähnlichen Instituten werden neuerdings sog. Selbstbedienungs-Servicedrucker eingesetzt, mit deren Hilfe es dem Bankkunden möglich ist, nach dem Einstecken einer Berechtigungskarte sich beispielsweise einen Kontoauszug von seinem Girokonto erstellen zu lassen. Diese Kontoauszüge haben normalerweise eine ganz bestimmte Länge, und in einigen Fällen kann es vorkommen, daß der Kunde solange seine Kontoauszüge nicht abgeholt hat, daß ein Formular nicht dafür ausreicht, sämtliche Kontenbewegungen aufzunehmen. In diesem Falle ist es unzweckmäßig, die gedruckten Kontoauszüge einzeln auszugeben, solange nicht der Drucker mit dem Aufnehmen der auszugebenden Daten fertig ist.In banks and similar institutions, so-called self-service printers are now being used, with the help of which bank customers can, for example, create an account statement from their checking account after inserting an authorization card. These bank statements are usually of a certain length, and in some cases the customer may not have collected his bank statements as long as one form is not sufficient to record all account movements. In this case, it is impractical to print out the printed bank statements one by one, as long as the printer is not ready to record the data to be printed out.

Aufgabe der Erfindung ist es daher, für einen solchen Selbstbedienungs-Servicedrucker eine Stapelvorrichtung zu schaffen, die es erlaubt, die bedruckten Belege solange festzuhalten, bis der Drucker mit dem Ausdruck aller Daten fertig ist. Entsprechend der Aufgabenstellung wird es sich dabei um die Stapelung von jedenfalls nicht mehr als von 10 bis 20 Belegen handeln. Es ist die Aufgabe der Erfindung, für solch einen speziellen Zweck eine Stapelvorrichtung zu schaffen.The object of the invention is therefore to provide a stacking device for such a self-service printer, which allows the printed receipts to be held until the printer has finished printing all the data. Depending on the task, it will be a stack of no more than 10 to 20 documents. It is the object of the invention to provide a stacking device for such a special purpose.

Die Erfindung betrifft eine Einrichtung gemäß Anspruch 1.The invention relates to a device according to claim 1.

Gemäß der weiteren Erfindung sind in Transportrichtung vor dem ersten Transportrollenpaar Führungsflächen vorgesehen, die beiderseits den Stapelraum begrenzen. Vor dem Stapelraum sind noch zweite Transportrollenpaare vorgesehen, die die Belege von dem Drucker weg und zu dem Stapelraum zuführen.According to the further invention, guide surfaces are provided in the direction of transport in front of the first pair of transport rollers, which limit the stacking space on both sides. In front of the stacking space, two pairs of transport rollers are also provided, which feed the receipts away from the printer and to the stacking space.

Gemäß einem weiteren Merkmal der Erfindung werden die Andrückrollen der ersten und zweiten Transportrollenpaare so gesteuert, daß sie mechanisch zwangsläufig abwechselnd mit den Antriebsrollen in Wirkverbindung gebracht werden. Hierzu sind die Andrückrollen des ersten Transportrollenpaares auf einer gemeinsamen Achse oberhalb der Antriebsrollen gelagert, während die Andrückrollen des zweiten Transportrollenpaares unterhalb der Antriebsrollen vorgesehen sind. Die Achsen der Andrückrollenpaare werden von einem Steuerhebel gehalten, der Bestandteil der Steuereinrichtung ist und der in seinen beiden Wirkstellungen entweder die Andrückrollen des ersten Transportrollenpaares oder die Andrückrollen des zweiten Transportrollenpaares in die Wirkstellung bringt.According to a further feature of the invention, the pressure rollers of the first and second pairs of transport rollers are controlled in such a way that they are mechanically inevitably brought into operative connection with the drive rollers. For this purpose, the pressure rollers of the first pair of transport rollers are mounted on a common axis above the drive rollers, while the pressure rollers of the second pair of transport rollers are provided below the drive rollers. The axes of the pressure roller pairs are held by a control lever which is part of the control device and which, in its two operative positions, brings either the pressure rollers of the first pair of transport rollers or the pressure rollers of the second pair of transport rollers into the active position.

Die erfindungsgemäße Einrichtung hat den Vorteil, daß mit einem sehr geringen Aufwand an Teilen eine wirkungsvolle Stapelung der auszugebenden Belege erfolgen kann und daß der Drucker selbst bestimmt, wann die endgültige Ausgabe des Belegstapels erfolgt, so daß der Kunde mit Sicherheit die Dokumente über alle auf seinem Konto stattgefundenen Bewegungen erhält.The device according to the invention has the advantage that an effective stacking of the receipts to be issued can be carried out with a very low expenditure of parts and that the printer itself determines when the final issuing of the receipt stack takes place, so that the customer can be sure of the documents on everyone on his Account for movements that have taken place.

In den beiliegenden Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. In diesen Zeichnungen zeigt

  • FIG. 1 einen Schnitt durch den gesamten Servicedrucker,
  • FIG. 2 ist eine Draufsicht auf die Stapelvorrichtung,
  • FIG. 3 zeigt die mechanischen Teile der Steuereinrichtung,
  • FIG. 4 nd 5 zeigen verschiedene Funktionsstellungen der Teile, während
  • FIG. 6 eine Ansicht des Getriebes für die Transportrollen darstellt.
In the accompanying drawings, an embodiment of the invention is shown. In these drawings shows
  • FIG. 1 a section through the entire service printer,
  • FIG. 2 is a top view of the stacker,
  • FIG. 3 shows the mechanical parts of the control device,
  • FIG. 4 and 5 show different functional positions of the parts during
  • FIG. 6 shows a view of the gear for the transport rollers.

Wie die FIG. 1 erkennen läßt, ist in einem Behälter 1, der unter dem Servicedrucker angeordnet ist, ein Papierstapel 2 in Leporelloform vorgesehen, dessen Formularbahn 3 dem Servicedrucker 4 zugeführt wird. Der Drucker hat unter einer Haube 5 eine Papierzuführung über Stifträder 6 zu einer Druckunterlage 7. Die Stifträder 6 werden über einen Motor 8 und einen Riemen 9 angetrieben. Durch Andrückklappen 10 werden die Formularbahnen an die Stifträder angepreßt.As the FIG. 1 reveals, in a container 1, which is arranged under the service printer, a paper stack 2 is provided in fan-fold form, the form web 3 of which is fed to the service printer 4. Under a hood 5, the printer has a paper feed via pin wheels 6 to a printing pad 7. The pin wheels 6 are driven by a motor 8 and a belt 9. The form webs are pressed against the pin wheels by pressure flaps 10.

Über Führungsteile 11 werden die Formularbahnen 3 der Druckunterlage 7 und dem Druckkopf 12 zugeführt. Dieser Druckkopf 12 ist auf einem Schlitten 13 auf zwei Achsen 14 und 15 transversal verschieblich angeordnet. Der Druckkopf 12 ist vorzugsweise ein Nadeldruckkopf, es kann aber auch jeder andere Matrixdruckkopf Verwendung finden. An dem Druckschlitten 13 ist ein Schneidrad 16 vorgesehen, das im Zusammenwirken mit einer an der Druckunterlage 7 vorgesehenen Schneidkante 17 bewegt wird, wenn dies erforderlich ist und so die einzelnen Kontoauszüge abschneidet.The form webs 3 are fed to the print substrate 7 and the print head 12 via guide parts 11. This print head 12 is arranged on a carriage 13 on two axes 14 and 15 to be transversely displaceable. The print head 12 is preferably a needle print head, but any other matrix print head can also be used. A cutting wheel 16 is provided on the printing carriage 13, which is moved in cooperation with a cutting edge 17 provided on the printing pad 7 when this is necessary and thus cuts off the individual account statements.

Zwischen zwei Führungsplatten 18 und 19 wird der Beleg 20 dann vor dem Abschneiden einem Transportrollenpaar 21 zugeführt, dem zweiten Transportrollenpaar. Dieses Transportrollenpaar besteht aus Antriebsrollen 22 und Andrückrollen 23. Ein Fühler 24 stellt fest, ob sich ein Beleg zwischen den Transportrollen 21 befindet und meldet das Nichtvorhandensein eines solchen Beleges den elektronischen Teilen der Steuereinrichtung, die in den Zeichnungen nicht gezeigt sind. Ist ein Beleg 20 fertig bedruckt, schließt das Rollenpaar 21. Danach wird der Beleg 20 von der Formularbahn 3 abgeschnitten. Das Transportrollenpaar 21 ist während des Schneidvorganges durch das Schneidrad 16 geschlossen und wirkt damit als Klemmleiste für das Formular 20. Danach transportiert das Rollenpaar 20 den Beleg in Richtung Speicherraum 25. Nachdem der Beleg 20 das Transportrollenpaar 21 passiert hat, wird er in einen Speicherraum 25 geleitet, der durch eine untere Führungsplatte 26 und zwei obere Führungsplatten 27 und 28 begrenzt wird. Die Führungsplatte 19 ist zu den Transportrollenpaaren 21 so angeordnet, daß der Beleg 20 nach oben umgelenkt wird und dann gegen die Führungsplatte 27 stößt, um entlang den Führungsplatten 27 und 28 zwischen die Transportrollen 31 geführt zu werden.Between two guide plates 18 and 19, the document 20 is then fed to a pair of transport rollers 21, the second pair of transport rollers, before being cut off. This pair of transport rollers consists of drive rollers 22 and pressure rollers 23. A sensor 24 determines whether there is a document between the transport rollers 21 and reports the absence of such a document to the electronic parts of the control device, which are not shown in the drawings. When a receipt 20 has been printed, the pair of rollers 21 closes. The receipt 20 is then cut off from the form web 3. The pair of transport rollers 21 is closed by the cutting wheel 16 during the cutting process and thus acts as a clamping strip for the form 20. The pair of rollers 20 then transports the document in the direction of the storage space 25. After the document 20 has passed the pair of transport rollers 21, it becomes a storage space 25 passed, which is limited by a lower guide plate 26 and two upper guide plates 27 and 28. The guide plate 19 is arranged in relation to the pairs of transport rollers 21 in such a way that the document 20 is deflected upward and then abuts against the guide plate 27 in order to be guided along the guide plates 27 and 28 between the transport rollers 31.

In dem Gehäuse 5 ist eine Ausgabeöffnung 29 vorgesehen, durch welche die Belege ausgegeben werden können. Diese Ausgabeöffnung wird verschlossen durch eine Schwenkklappe 30. Unmittelbar hinter der Schwenkklappe 30 sind die ersten Transportrollen 31 vorgesehen, die aus oberen Andrückrollen 32 und aus unteren Antriebsrollen 33 bestehen. Wie sich insbesondere aus FIG. 2 ergibt, sind die Antriebsrollen 22 auf einer Achse 34 zwischen zwei Platinen 35 und 36 gehalten. Die Andrückrollen 23 werden von einer Achse 37 getragen, die zwischen zwei Steuerhebeln 38 und 39 beidseits der Platinen 35 und 36 gehalten sind. Die Steuerhebel 38 und 39 gehören als mechanische Teile zu der Steuereinrichtung 40, zu der außer dem mechanischen Teil auch noch die entsprechenden elektronischen Teile gehören, die in den Zeichnungen jedoch nicht dargestellt sind.An output opening 29 is provided in the housing 5, through which the receipts can be output. This dispensing opening is closed by a swivel flap 30. Immediately behind the swivel flap 30, the first transport rollers 31 are provided, which consist of upper pressure rollers 32 and lower drive rollers 33. As can be seen in particular from FIG. 2 results the drive rollers 22 are held on an axis 34 between two boards 35 and 36. The pressure rollers 23 are supported by an axis 37, which are held between two control levers 38 and 39 on both sides of the plates 35 and 36. The control levers 38 and 39 belong to the control device 40 as mechanical parts, which also include the corresponding electronic parts in addition to the mechanical part, but which are not shown in the drawings.

Die beiden Hebel 38 und 39 haben die Aufgabe, sowohl die Andrückrollen 23 der zweiten Transportrollen 21 als auch die Andrückrollen 32 der ersten Transportrollen 31 abwechselnd in die Wirkstellung bzw. außer Wirkstellung zu bringen. Die Andrückrollen 23 und 32 sind aus einem Material mit hohem Reibwert und niedriger Shore-Härte hergestellt, damit sie elastisch anliegend sicher transportieren. Der Verschleiß kann damit zu einem gewissen Grad aufgefangen werden, Einstellungen sind kaum nötig, und es wird außerdem eine Geräuschminderung erzielt.The two levers 38 and 39 have the task of alternately bringing both the pressure rollers 23 of the second transport rollers 21 and the pressure rollers 32 of the first transport rollers 31 into the active position or out of the active position. The pressure rollers 23 and 32 are made of a material with a high coefficient of friction and a low Shore hardness, so that they can be transported securely in an elastic manner. The wear can be compensated to a certain extent, adjustments are hardly necessary, and noise is also reduced.

Hierfür sind auch die Andrückrollen 32 der ersten Transportrollen 31 auf einer Achse 80 zwischen den beiden Steuerhebeln 38 und 39 gehalten. Die Antriebsrollen 33 der ersten Transportrollen 31 sind wie die Antriebsrollen 22 der zweiten Transportrollen 21 zwischen den beiden Platinen 35 und 36 auf einer Achse 52 gelagert.For this purpose, the pressure rollers 32 of the first transport rollers 31 are also held on an axis 80 between the two control levers 38 and 39. The drive rollers 33 of the first transport rollers 31, like the drive rollers 22 of the second transport rollers 21, are mounted on an axis 52 between the two plates 35 and 36.

Dem Antrieb der Antriebsrollen 22 und 33 dienen die Teile, die in FIG. 2 links dargestellt sind und die sich auch in Seitenansicht aus der FIG. 6 ergeben. Ein Motor 41 treibt über ein Ritzel 42 und ein Zahnrad 43 ein Riemenrad 44 an, welches einen Transportriemen 45 bewegt, der weiterhin über ein Riemenrad 46 geführt ist, welches mit der Achse 34 der ersten Transportrolle 31 verbunden ist. Das Zahnrad 43 und das Riemenrad 44 bilden ein Teil mit einem weiteren Ritzel 47, welches mit einem Zahnrad 48 im Eingriff steht. Das Zahnrad 48 ist gleichzeitig verbunden mit einem Riemenrad 49, welches über einen Riemen 50 ein Riemenrad 51 und damit die Achse 52 antreibt, auf der die Antriebsrollen 33 der ersten Transportrollen 31 gelagert sind. Zwischen dem Riemenrad 51 und der Achse 52 ist ein Reibungsschluß vorhanden, so daß die Antriebsrollen 33 beim Entnehmen der Belege sich drehen können, ohne daß ein weiterer Antrieb durch den Motor 41 erfolgt. Von dem Motor 41 werden also sowohl die Antriebsrollen 22 als auch die Antriebsrollen 33 angetrieben.The parts that are shown in FIG. 2 are shown on the left and which can also be seen in a side view from FIG. 6 result. A motor 41 drives a belt wheel 44 via a pinion 42 and a gear wheel 43, which moves a transport belt 45, which is also guided via a belt wheel 46 which is connected to the axis 34 of the first transport roller 31. The gear 43 and the belt wheel 44 form part with a further pinion 47, which is in engagement with a gear 48. The gear 48 is simultaneously connected to a belt wheel 49, which drives a belt wheel 51 and thus the axis 52 via a belt 50, on which the drive rollers 33 of the first transport rollers 31 are mounted. A frictional engagement is present between the pulley 51 and the axis 52, so that the drive rollers 33 can rotate when the receipts are removed without the motor 41 driving them further. Both the drive rollers 22 and the drive rollers 33 are thus driven by the motor 41.

Ähnlich wie die Andrückrollen 32 und 23 zwischen den beiden Steuerhebeln 38 und 39 gehalten sind, ist die Schwenkklappe 30 zwischen den beiden Steuerhebeln 53 und 54 gehalten. Hierfür sind die beiden Steuerhebel 38 und 39 auf einer gemeinsamen Schwenkachse 66 angeordnet, die beiden Steuerhebel 53 und 54 auf einer gemeinsamen Schwenkachse 56. Die Schwenkachse 55 wirkt übrigens als Torsionsfeder, die dafür sorgt, daß die Andrückrollen 23 und 32 auf der ganzen Länge ihrer Achsen 37 und 80 mit Druck an den Antriebsrollen 22 und 33 anliegen. Ihre Steuerbewegung erhalten die Steuerhebel 38 und 39 durch eine Abfühlrolle 57, die beiden Steuerhebel 53 und 54 über eine Abfühlrolle 58. Die Abfühlrollen 57 und 58 arbeiten mit Nockenscheiben 59 und 60 zusammen, die zusammen mit anderen Nockenscheiben 61, 62 und 63 auf einer Nockenwelle 64 angeordnet sind. Alle diese Teile sind mechanische Bestandteile der Steuereinrichtung 40. Die Steuerbewegung wird erteilt von einem Motor 64, der an der Platine 35 befestigt ist und der über ein Ritzel 65 und ein Zahnrad 66 über eine Welle 67 ein weiteres Ritzel 68 antreibt, das mit einem Zahnrad 69 in Eingriff steht. Über ein kleines Zahrad 70 wird das Zahnrad 71 angetrieben, welches mit der Achse 64 der Nockenscheiben 59 bis 63 verbunden ist. Durch die Verwendung der beiden Motore 41 für die Transportbewegung und 64 für die Steuerbewegungen ist es möglich, Transportbewegungen und Steuerbewegungen vollkommen getrennt voneinander anzusteuern, so daß die elektronische Ansteuerung übersichtlich und einfach wird. Die Nockenwelle 64 betätigt nicht nur über die Abfühlrollen 57 und 58 die beiden Steuerhebel 38 und 54, sondern auch noch eine Anzahl von Mikroschaltern 72, 73 und 74, die von den Nockenscheiben 61 bis 63 betätigt werden und die die verschiedenen Funktionszustände an die Elektronik melden. In FIG. 2 erkennt man in der Nähe der Schwenkklappe 30 noch einen Fühler 75, der über ein entsprechendes Gestänge 76 einen weiteren Mikroschalter 77 betätigt. Dieser Fühler 75 hat die Aufgabe zu melden, ob zwischen den Transportrollen 31 Papier vorhanden ist oder nicht.Similar to how the pressure rollers 32 and 23 are held between the two control levers 38 and 39, the swivel flap 30 is held between the two control levers 53 and 54. For this purpose, the two control levers 38 and 39 are arranged on a common pivot axis 66, the two control levers 53 and 54 on a common pivot axis 56. Incidentally, the pivot axis 55 acts as a torsion spring, which ensures that the pressure rollers 23 and 32 along their entire length Axles 37 and 80 press against the drive rollers 22 and 33. The control levers 38 and 39 receive their control movement by means of a sensing roller 57, the two control levers 53 and 54 via a sensing roller 58. The sensing rollers 57 and 58 work together with cam disks 59 and 60, which together with other cam disks 61, 62 and 63 on a camshaft 64 are arranged. All of these parts are mechanical components of the control device 40. The control movement is given by a motor 64 which is fastened to the circuit board 35 and which drives a further pinion 68 via a pinion 65 and a gearwheel 66 via a shaft 67, said pinion 68 having a gearwheel 69 is engaged. The gear 71, which is connected to the axis 64 of the cam disks 59 to 63, is driven via a small gear wheel 70. By using the two motors 41 for the transport movement and 64 for the control movements, it is possible to control transport movements and control movements completely separately from one another, so that the electronic control becomes clear and simple. The camshaft 64 not only actuates the two control levers 38 and 54 via the sensing rollers 57 and 58, but also a number of microswitches 72, 73 and 74 which are actuated by the cam disks 61 to 63 and which report the various functional states to the electronics . In FIG. 2, a sensor 75 can be seen in the vicinity of the swivel flap 30, which actuates a further microswitch 77 via a corresponding linkage 76. This sensor 75 has the task of reporting whether paper is present between the transport rollers 31 or not.

Die Funktion des Anmeldungsgegenstandes wird vielleicht am deutlichsten beim Vergleich der Stellung der Schwenkklappe 30 und der Transportrollenpaare 31 und 21 in den verschiedenen Stellungen, wie sie in den FIG. 1, 4 und 5 gezeigt sind. Dabei stellt FIG. 4 die Grundstellung dar. Eine Anzahl Belege ist zwischen den ersten Transportrollen 31 gestapelt und festgeklemmt, die Schwenkklappe 30 ist abgesenkt, so daß die Belege nicht heraus können. Die Schwenkklappe 30 wirkt während des Vortreibens des Beleges 20 gleichzeitig als Anschlag. Dieser Anschlag enthält noch Dämpfungsfedern 78, die an der Schwenkklappe 30 als Blattfedern befestigt sind. Man erkennt in FIG. 4, daß die Transportrollenpaare 31 einander berühren, so daß die hier befindlichen Belege sich nicht verschieben können. Anders dagegen die Transportrollen 21, die in diesem Falle geöffnet sind, so daß ein neuer Beleg 20, der zwischen den Führungsplatten 18 und 19 zugeführt wird, zwischen die Antriebsrollen 22 und die Andrückrollen 23 eintreten kann. Dies ist die sog. Grundstellung, in der sich die Teile der Stapelvorrichtung in Ruhe befinden.The function of the subject of the application is perhaps most evident when comparing the position of the swivel flap 30 and the pairs of transport rollers 31 and 21 in the different positions, as shown in FIGS. 1, 4 and 5 are shown. FIG. 4 shows the basic position. A number of documents are stacked and clamped between the first transport rollers 31, the swivel flap 30 is lowered so that the documents cannot come out. The pivoting flap 30 also acts as a stop while advancing the document 20. This stop also contains damping springs 78 which are fastened to the swivel flap 30 as leaf springs. One can see in FIG. 4 that the pairs of transport rollers 31 touch each other, so that the documents located here cannot move. In contrast, the transport rollers 21, which are open in this case, so that a new document 20, which is fed between the guide plates 18 and 19, can enter between the drive rollers 22 and the pressure rollers 23. This is the so-called basic position in which the parts of the stacking device are at rest.

Soll eingestapelt werden, so nehmen die Teile die Stellung gemäß FIG. 1 ein, die zweiten Transportrollen 21 sind geschlossen, die Antriebsrollen 22 werden angetrieben, der Beleg bewegt sich zwischen den Führungsblechen 27 und 28 einerseits und dem Führungsblech 26 andererseits in Richtung auf die ersten Transportrollen 31, die in diesem Falle geöffnet sind und gegen die Schwenkklappe 30, die in diesem Falle geschlossen ist. Federn 78 dämpfen den Anschlag der Belege 20 an der Schwenkklappe 30. Sobald der Fühler 24 feststellt, daß kein Beleg mehr zwischen den Transportrollen 21 ist, wird durch den Motor 64 die Steuereinrichtung 40 wieder in die Grundstellung gemäß FIG. 4 zurückgeführt, d.h. die eingestapelten Belege 20 werden zwischen den Transportrollen 31 festgeklemmt und die Transportrollen 21 sind geöffnet, um erneut einen Beleg aufzunehmen.If stacking is to take place, the parts take the position according to FIG. 1 a, the second transport rollers 21 are closed, the drive rollers 22 are driven, the document moves between the guide plates 27 and 28 on the one hand and the guide plate 26 on the other hand in the direction of the first transport rollers 31, which are open in this case and against the swivel flap 30, which is closed in this case. Springs 78 dampen the stop of the documents 20 on the swivel flap 30. As soon as the sensor 24 determines that there is no longer any document between the transport rollers 21, the control device 40 is moved back into the motor 64 by the motor 64 Basic position according to FIG. 4 returned, ie the stacked documents 20 are clamped between the transport rollers 31 and the transport rollers 21 are opened in order to take up a document again.

Wird nun vom Drucker ein Signal gegeben, daß der Druckvorgang abgeschlossen ist, daß also die Belege ausgegeben bzw. entnommen werden können, dann behalten die Transportrollen 21 und 31 ihre Stellung gemäß FIG. 4, d.h. die Stellung, die sie in der Grundstellung einnehmen. Es wird lediglich der Steuerhebel 54 über die Abfühlrolle 58 so angehoben, daß nun die Belege durch die Ausgabeöffnung austreten können, wie dies FIG. 5 zeigt. Gleichzeitig wird aber auch der Motor 41 bestromt, so daß die Antriebsrollen 33 um ein gewisses Maß angetrieben werden, d.h. der Belegstapel wird bis zu einem ganz bestimmten Grade vorgeschoben. Es ist dann der Bedienungsperson überlassen, den Stapel anzufassen und herauszuziehen, was durch den Reibungsschluß zwischen der Achse 52 und dem Riemenrad 51 ermöglicht wird. Sobald der Fühler 75 meldet, daß keine Belege mehr zwischen den Transportrollen 31 vorhanden sind, wird an die Elektronik der Steuereinrichtung der Befehl gegeben, die Anordnung wieder in die Grundstellung gemäß FIG. 4 zurückzuführen, d.h. also insbesondere die Schwenkklappe 30 wieder in ihre Ausgangsstellung zu bringen.If a signal is now given by the printer that the printing process is complete, that is to say that the receipts can be issued or removed, then the transport rollers 21 and 31 retain their position according to FIG. 4, i.e. the position they occupy in the basic position. Only the control lever 54 is raised above the sensing roller 58 so that the receipts can now exit through the dispensing opening, as shown in FIG. 5 shows. At the same time, however, the motor 41 is also energized, so that the drive rollers 33 are driven to a certain extent, i.e. The document stack is advanced to a certain degree. It is then up to the operator to grip and pull out the stack, which is made possible by the frictional engagement between the axle 52 and the pulley 51. As soon as the sensor 75 reports that there are no longer any documents between the transport rollers 31, the electronics of the control device are given the command to return the arrangement to the basic position according to FIG. 4 attributed, i.e. thus in particular to bring the swivel flap 30 back into its starting position.

Claims (10)

1. A device for temporarily stacking documents prior to their controlled output for combination with a self-service printer, comprising an output opening (29) for the ejection of the stacked documents (20), a swing gate (30) which opens and closes the output opening (29) and which serves as stop means for the documents (20) to be stacked, a first pair of transportation rollers (31) consisting of drive rollers (22) and pressure rollers (33) which are arranged directly in front of the swing gate (30) considered in the transportation direction and which serves on the one hand to cumulatively retain and on the other hand to transport a plurality of documents (20), and a control device (40) for the flow control of the opening and closing movement of the swing gate (30) and of the pair of transportation rollers (31) and their drive means, wherein
a) the introduction of the documents (20) into the device takes place with the swing gate (30) closed and the pair of transportation rollers (31) open,
b) the documents are held fast with the swing gate (30) closed and the pair of transportation rollers (31) closed but not driven and
c) for the output of the documents (20) the swing gate (30) is opened and the pair of transportation rollers (31) is closed and driven.
2. A device as claimed in Claim 1, characterised in that a stacking space (25) which comprises upper and lower guide plates (27, 28, 26) is arranged in front of the pair of transportation rollers (31) considered in the direction of transportation.
3. A device as claimed in Claim 2, characterised in that in front of the stacking space (25) considered in the direction of transportation is arranged a second pair of transportation rollers (21) which com- ' prises drive rollers (22) and pressure rollers (23) and which is driven by the control device (40) in the opposite direction to the first pairs of transportation rollers (31) and which serves to conduct the documents (20) to the first pair of transportation rollers (31).
4. A device as claimed in Claim 1, characterised in that the control device (40) comprises a cam control unit (59 to 63) which is driven in both directions of rotation by a motor (64).
5. A device as claimed in Claim 3, characterised in that the oppositely directed drive of the first and second pairs of transportation rollers (31, 21) takes place in such manner that the pressure rollers (32) of the first pair of transportation rollers (31) are arranged above the drive rollers (22, 33) and the pressure rollers (23) of the second pair of transportation rollers (21) are arranged below the drive rollers (22, 23) and that the pressure rollers (32, 23) of the first and second pairs of transportation rollers (31, 21) are supported by a common control lever (38) which forms part of the control device and which in its two opposite positions brings either one or the other of the pressure rollers (23, 32) into contact with the drive rollers (22, 33).
6. A device as claimed in Claim 4, characterised in that the drive rollers (33, 22) are driven by a separate motor (41).
7. A device as claimed in Claim 1, characterised in that on the inside of the swing gate (30) are arranged damping springs (78) which brake the impact of the documents before they reach the swing gate (30).
8. A device as claimed in Claim 3, characterised in that a guide plate (19) conducts the documents (20) to the second pair of transportation rollers (21) in a direction such that the document is guided upwards and is thus guided by the upper guide plates (27, 28) into the stacking position between the first pair of transportation rollers (31).
9. A device as claimed in Claim 5, characterised in that the control levers (38 and 39) are connected to one another by a swing axle (55) which acts as torsion spring and which assures the contact of the drive rollers (32) and pressure rollers (33) along the entire length of the pressure roller axles (37, 80).
10. A device as claimed in Claims 1 and 3, characterised in that the drive rollers (32) and pressure rollers (33) are produced from a material having a high friction coefficient and low Shore hardness.
