Definitions

  • the invention relates to a paper delivery device comprising a discharge opening for removing a sheet and a movable guide plate for guiding the sheet to the discharge opening, wherein the guide plate is fixed to an axle.
  • self-service machines are increasingly used, for example ATMs, reverse vending machines, ticket vending machines and parking machines.
  • the mentioned machines have in common that they have a printer for printing eg a receipt, a voucher, a billing voucher, a voucher or an admission ticket. It happens occasionally that a user removes the printed paper from the machine before printing is finished. As a result, the paper can be printed incorrectly or it breaks off too early or unnecessarily much paper is promoted. This may damage the printer or other parts of the self-service machine.
  • a jam in the printer can be caused by a blockage at a discharge opening.
  • the paper jam may cause the paper to be printed incorrectly or components to be damaged.
  • the WO 2013/023544 A1 a paper output device by means of which an early paper removal and a paper blockade can be detected at a paper discharge opening. Another device for detecting an early paper removal is in the US 2008/0229892 A1 disclosed.
  • the object of the present invention is to design a paper output device which has a comparatively simple structure and by means of which early paper removal or paper blockade can be detected.
  • the paper dispenser according to the invention comprises a dispensing opening for removing a sheet and a movable guide plate for guiding the sheet to the dispensing opening, wherein the guide plate is attached at least on one axis.
  • the axis is displaceable and rotatably mounted in a guide groove. Depending on where the blade presses against the guide plate, the axle is either shifted or rotated.
  • a first sensor is provided for detecting a position of the axis in the guide groove and a second sensor is provided for detecting a rotational position of the axis in the guide groove.
  • the displaceable mounting of the axis in the guide groove should mean that the axis can be displaced along a longitudinal direction of the guide groove.
  • the paper dispensing device according to the invention is characterized by a particularly robust and comparatively simple construction. With the paper output device can be detected by simple means a premature paper removal.
  • the axis can be at least two positions in Take the longitudinal direction of the guide groove. When a user pulls on the paper in a premature paper removal, the paper usually abuts against the guide plate, whereby a force is exerted on the guide plate. By this force exerted on the guide plate, the axis shifts in the longitudinal direction of the guide groove. As a result, the position of the axis changes in the guide groove, which in turn can be detected by the first sensor. Thus, with the first sensor, a displacement of the axis in the guide groove can be detected.
  • the axis is additionally rotatably mounted in the guide groove.
  • a second sensor is provided for detecting a rotational position of the axis. If the dispensing opening is e.g. accidentally blocked by a user, may result in a paper jam in the paper output device. With the said paper output device, this paper jam can now be detected or a blockage of the discharge opening can be detected. In the case of a locked dispensing opening or jam, the paper typically bulges and presses against the guide plate. Consequently, a torque acts on the guide plate, whereby the guide plate rotates about the bearing in the guide groove axis. The changed rotational position of the axis in the guide groove can then be detected by the second sensor. Thus, with the second sensor, a rotation of the axis in the guide groove can be detected.
  • a first return element is provided for returning the axle to a specific position in the guide groove. This can ensure that the guide plate is usually in a predetermined first position in a paper output. If a user wishes to remove the paper prematurely, the axis is moved to a second or further position in the guide groove. After eliminating the fault, the axis is brought back into the first position by means of the first return element.
  • a second return element for returning the axle is provided in a certain rotational position. If the discharge port becomes jammed and the paper can no longer be conveyed freely out of the paper delivery device, the paper typically rotates Axis in the guide groove. If the blockage of the discharge opening is no longer present, the second return element can return the axis to a predetermined rotational position.

Es kommt gelegentlich vor, dass ein Benutzer das bedruckte Papier aus dem Automaten entnimmt, bevor der Druckvorgang beendet ist. Hierdurch kann das Papier fehlerhaft bedruckt werden oder es reiƟt zu frĆ¼h ab oder es wird unnƶtig viel Papier gefƶrdert. Hierdurch kƶnnen unter UmstƤnden der Drucker oder andere Teile des Selbstbedienungsautomaten beschƤdigt werden.Nowadays self-service machines are increasingly used, for example ATMs, reverse vending machines, ticket vending machines and parking machines. The mentioned machines have in common that they have a printer for printing eg a receipt, a voucher, a billing voucher, a voucher or an admission ticket. It happens occasionally that a user removes the printed paper from the machine before printing is finished. As a result, the paper can be printed incorrectly or it breaks off too early or unnecessarily much paper is promoted. This may damage the printer or other parts of the self-service machine.

Weiterhin kann bei einer Blockade an einer Ausgabeƶffnung ein Papierstau im Drucker verursacht werden. Durch den Papierstau kann das Papier fehlerhaft bedruckt werden oder es kƶnnen Bauteile beschƤdigt werden.Furthermore, a jam in the printer can be caused by a blockage at a discharge opening. The paper jam may cause the paper to be printed incorrectly or components to be damaged.

Um die genannten Probleme zu vermeiden, weist die WO 2013/023544 A1 eine Papierausgabeeinrichtung auf, mittels derer eine frĆ¼hzeitige Papierentnahme und eine Papierblockade an einer Papierausgabeƶffnung erkannt werden kƶnnen. Eine weitere Vorrichtung zum Erkennen einer frĆ¼hzeitigen Papierentnahme ist in der US 2008/0229892 A1 offenbart.To avoid the problems mentioned, the WO 2013/023544 A1 a paper output device by means of which an early paper removal and a paper blockade can be detected at a paper discharge opening. Another device for detecting an early paper removal is in the US 2008/0229892 A1 disclosed.

Aufgabe der vorliegenden Erfindung ist es, eine Papierausgabeeinrichtung zu konzipieren, welche einen vergleichsweise einfachen Aufbau aufweist, und mittels derer eine frĆ¼hzeitige Papierentnahme oder eine Papierblockade detektiert werden kann.The object of the present invention is to design a paper output device which has a comparatively simple structure and by means of which early paper removal or paper blockade can be detected.

Diese Aufgabe wird durch eine Papierausgabeeinrichtung gemƤƟ dem Hauptanspruch gelƶst. Vorteilhafte Weiterbildungen ergeben sich mit den Merkmalen der UnteransprĆ¼che sowie der AusfĆ¼hrungsbeispiele.This object is achieved by a paper output device according to the main claim. Advantageous developments emerge with the features of the subclaims and the embodiments.

Die erfindungsgemƤƟe Papierausgabeeinrichtung umfasst eine Ausgabeƶffnung zum Entnehmen eines Blattes und eine bewegliche FĆ¼hrungsplatte zum FĆ¼hren des Blattes zur Ausgabeƶffnung, wobei die FĆ¼hrungsplatte zumindest an einer Achse befestigt ist. Die Achse ist in einer FĆ¼hrungsnut verschiebbar und drehbar gelagert. Je nachdem, wo das Blatt gegen die FĆ¼hrungsplatte drĆ¼ckt, wird die Achse entweder verschoben oder gedreht. Ein erster Sensor ist vorgesehen zum Detektieren einer Position der Achse in der FĆ¼hrungsnut und ein zweiter Sensor ist vorgesehen zum Erkennen einer Drehstellung der Achse in der FĆ¼hrungsnut.The paper dispenser according to the invention comprises a dispensing opening for removing a sheet and a movable guide plate for guiding the sheet to the dispensing opening, wherein the guide plate is attached at least on one axis. The axis is displaceable and rotatably mounted in a guide groove. Depending on where the blade presses against the guide plate, the axle is either shifted or rotated. A first sensor is provided for detecting a position of the axis in the guide groove and a second sensor is provided for detecting a rotational position of the axis in the guide groove.

Hierbei soll die verschiebbare Lagerung der Achse in der FĆ¼hrungsnut heiƟen, dass sich die Achse entlang einer LƤngsrichtung der FĆ¼hrungsnut verschieben lƤsst. Die erfindungsgemƤƟe Papierausgabeeinrichtung zeichnet sich durch einen besonders robusten und vergleichsweise einfachen Aufbau aus. Mit der Papierausgabeeinrichtung lƤsst sich mit einfachen Mitteln eine vorzeitige Papierentnahme detektieren. Die Achse kann mindestens zwei Positionen in LƤngsrichtung der FĆ¼hrungsnut einnehmen. Wenn ein Benutzer bei einer vorzeitigen Papierentnahme an dem Papier zieht, stĆ¶ĆŸt das Papier in der Regel gegen die FĆ¼hrungsplatte, wodurch eine Kraft auf die FĆ¼hrungsplatte ausgeĆ¼bt wird. Durch diese auf die FĆ¼hrungsplatte ausgeĆ¼bte Kraft verschiebt sich die Achse in LƤngsrichtung der FĆ¼hrungsnut. Infolgedessen Ƥndert sich die Position der Achse in der FĆ¼hrungsnut, was wiederum durch den ersten Sensor detektiert werden kann. Mit dem ersten Sensor kann also eine Verschiebung der Achse in der FĆ¼hrungsnut detektiert werden.Here, the displaceable mounting of the axis in the guide groove should mean that the axis can be displaced along a longitudinal direction of the guide groove. The paper dispensing device according to the invention is characterized by a particularly robust and comparatively simple construction. With the paper output device can be detected by simple means a premature paper removal. The axis can be at least two positions in Take the longitudinal direction of the guide groove. When a user pulls on the paper in a premature paper removal, the paper usually abuts against the guide plate, whereby a force is exerted on the guide plate. By this force exerted on the guide plate, the axis shifts in the longitudinal direction of the guide groove. As a result, the position of the axis changes in the guide groove, which in turn can be detected by the first sensor. Thus, with the first sensor, a displacement of the axis in the guide groove can be detected.

Weiterhin ist die Achse zusƤtzlich drehbar in der FĆ¼hrungsnut gelagert. Ein zweiter Sensor ist zum Erkennen einer Drehstellung der Achse vorgesehen. Falls die Ausgabeƶffnung z.B. versehentlich durch einen Benutzer blockiert wird, kann dies einen Papierstau in der Papierausgabeeinrichtung zur Folge haben. Mit der genannten Papierausgabeeinrichtung kann nun dieser Papierstau erkannt werden bzw. eine Blockade der Ausgabeƶffnung kann erkannt werden. Im Falle einer gesperrten Ausgabeƶffnung bzw. eines Papierstaus wƶlbt sich das Papier typischerweise und drĆ¼ckt gegen die FĆ¼hrungsplatte. Folglich wirkt ein Drehmoment auf die FĆ¼hrungsplatte, wodurch sich die FĆ¼hrungsplatte um die in der FĆ¼hrungsnut gelagerte Achse dreht. Die verƤnderte Drehstellung der Achse in der FĆ¼hrungsnut kann dann durch den zweiten Sensor detektiert werden. Mit dem zweiten Sensor kann also eine Drehung der Achse in der FĆ¼hrungsnut detektiert werden.Furthermore, the axis is additionally rotatably mounted in the guide groove. A second sensor is provided for detecting a rotational position of the axis. If the dispensing opening is e.g. accidentally blocked by a user, may result in a paper jam in the paper output device. With the said paper output device, this paper jam can now be detected or a blockage of the discharge opening can be detected. In the case of a locked dispensing opening or jam, the paper typically bulges and presses against the guide plate. Consequently, a torque acts on the guide plate, whereby the guide plate rotates about the bearing in the guide groove axis. The changed rotational position of the axis in the guide groove can then be detected by the second sensor. Thus, with the second sensor, a rotation of the axis in the guide groove can be detected.

Optional ist ein erstes RĆ¼ckstellelement zum RĆ¼ckstellen der Achse in eine bestimmte Position in der FĆ¼hrungsnut vorgesehen. Hierdurch kann sichergestellt werden, dass die FĆ¼hrungsplatte bei einer Papierausgabe in der Regel in einer vorbestimmten ersten Position ist. Falls ein Benutzer das Papier vorzeitig entnehmen mƶchte, wird die Achse in eine zweite oder eine weitere Position in der FĆ¼hrungsnut verschoben. Nach Beseitigung der Stƶrung wird die Achse mittels des ersten RĆ¼ckstellelements wieder in die erste Position gebracht.Optionally, a first return element is provided for returning the axle to a specific position in the guide groove. This can ensure that the guide plate is usually in a predetermined first position in a paper output. If a user wishes to remove the paper prematurely, the axis is moved to a second or further position in the guide groove. After eliminating the fault, the axis is brought back into the first position by means of the first return element.

In einer weiteren Ausgestaltung ist ein zweites RĆ¼ckstellelement zum RĆ¼ckstellen der Achse in eine bestimmte Drehstellung vorgesehen. Falls die Ausgabeƶffnung blockiert wird und das Papier nicht mehr ungehindert aus der Papierausgabeeinrichtung gefƶrdert werden kann, dreht sich typischerweise die Achse in der FĆ¼hrungsnut. Wenn die Blockade der Ausgabeƶffnung nicht mehr vorhanden ist, kann das zweite RĆ¼ckstellelement die Achse in eine vorbestimmte Drehstellung zurĆ¼ckstellen.In a further embodiment, a second return element for returning the axle is provided in a certain rotational position. If the discharge port becomes jammed and the paper can no longer be conveyed freely out of the paper delivery device, the paper typically rotates Axis in the guide groove. If the blockage of the discharge opening is no longer present, the second return element can return the axis to a predetermined rotational position.

ZweckmƤƟig sind der erste Sensor und/oder der zweite Sensor in oder an der FĆ¼hrungsnut angeordnet. Die genannten Sensoren kƶnnen hierdurch direkt erfassen, ob die Achse sich verschiebt oder sich dreht. FĆ¼r die Wahl des ersten Sensors und/oder des zweiten Sensors kommen verschiedene Sensoren in Betracht. Beispielsweise seien hier elektrooptische oder elektromagnetische Sensoren oder mechanische Schalter erwƤhnt. Vorzugsweise erfolgt eine berĆ¼hrungslose Erfassung einer Position der Achse in der FĆ¼hrungsnut oder einer Drehstellung der Achse in der FĆ¼hrungsnut durch den ersten bzw. den zweiten Sensor.Suitably, the first sensor and / or the second sensor are arranged in or on the guide groove. The aforementioned sensors can thereby detect directly whether the axis is shifting or rotating. For the choice of the first sensor and / or the second sensor different sensors come into consideration. For example, electro-optical or electromagnetic sensors or mechanical switches may be mentioned here. Preferably, a non-contact detection of a position of the axis in the guide groove or a rotational position of the axis in the guide groove by the first and the second sensor.

Typischerweise liegt der beweglichen FĆ¼hrungsplatte eine feststehende, an einem GehƤuse der Papierausgabeeinrichtung befestigte Leitplatte gegenĆ¼ber. In der Regel sind die FĆ¼hrungsplatte und die Leitplatte seitlich durch zwei SeitenwƤnde begrenzt. Die FĆ¼hrungsplatte und die Leitplatte bilden Ć¼blicherweise einen Papierfƶrderkanal, der eine Papierfƶrderung in Richtung der Ausgabeƶffnung erlaubt.Typically, the movable guide plate faces a fixed guide plate attached to a housing of the paper dispenser. In general, the guide plate and the guide plate are bounded laterally by two side walls. The guide plate and the guide plate usually form a paper feed channel, which allows a paper feed in the direction of the discharge opening.

Eine Drehung der Achse kann durch einen oder mehrere AnschlƤge begrenzt sein. Der Anschlag oder die AnschlƤge kƶnnen z.B. an der Achse, der FĆ¼hrungsplatte oder den SeitenwƤnden angeordnet sein.A rotation of the axis may be limited by one or more stops. The stop or stops may be e.g. be arranged on the axis, the guide plate or the side walls.

In der Regel ist die Leitplatte zumindest in einer Position der Achse in der FĆ¼hrungsnut oder einer Drehstellung der Achse in der FĆ¼hrungsnut parallel zur beweglichen FĆ¼hrungsplatte ausgerichtet. In einer Ausgestaltung ist die bewegliche FĆ¼hrungsplatte oberhalb der Leitplatte angeordnet. Bei einer vorzeitigen Papierentnahme wird dann die bewegliche FĆ¼hrungsplatte typischerweise nach oben bewegt und durch die Schwerkraft bedarf es keines ersten RĆ¼ckstellelements oder keines zweiten RĆ¼ckstellelements.In general, the guide plate is aligned at least in a position of the axis in the guide groove or a rotational position of the axis in the guide groove parallel to the movable guide plate. In one embodiment, the movable guide plate is arranged above the guide plate. In a premature paper removal then the movable guide plate is typically moved upward and by gravity, it requires no first return element or no second return element.

Die FĆ¼hrungsnut ist Ć¼blicherweise in zumindest einer der beiden SeitenwƤnde ausgebildet, vorzugsweise als lƤngliche Ausnehmung. Es kann auch in jeder Seitenwand eine FĆ¼hrungsnut vorgesehen sein. Bevorzugt ist die LƤngsrichtung der FĆ¼hrungsnut im Wesentlichen in vertikaler Richtung ausgerichtet. Hierbei ist die vertikale Richtung durch eine Richtung der auf die Papierausgabeeinrichtung wirkenden Schwerkraft definiert. Die LƤngsrichtung der FĆ¼hrungsnut kann je nach AusfĆ¼hrungsform auch andere Orientierungen aufweisen. So kann die FĆ¼hrungsnut eine geschwungene Form haben, z.B. zum Teil kreisbogenfƶrmig. Wichtig ist nur, dass die Achse sich in der FĆ¼hrungsnut verschieben lƤsst und dass eine vorzeitige Papierentnahme durch den ersten Sensor erkannt werden kann.The guide groove is usually formed in at least one of the two side walls, preferably as an elongated recess. It can also be provided in each side wall, a guide. The longitudinal direction is preferred the guide groove aligned substantially in the vertical direction. Here, the vertical direction is defined by a direction of the gravity acting on the paper discharger. The longitudinal direction of the guide groove may also have other orientations, depending on the embodiment. Thus, the guide can have a curved shape, for example, partially circular arc. It is only important that the axis can be moved in the guide groove and that premature paper removal can be detected by the first sensor.

Die bewegliche FĆ¼hrungsplatte kann auch unterhalb der Leitplatte angeordnet sein. In dieser Ausbildung ist es zweckmƤƟig, wenn das erste RĆ¼ckstellelement in der FĆ¼hrungsnut vorgesehen ist. Ɯblicherweise weist die FĆ¼hrungsplatte ein der Ausgabeƶffnung zugewandtes Ende und ein der Ausgabeƶffnung abgewandtes Ende auf. Die Achse ist typischerweise an dem der Ausgabeƶffnung zugewandten Ende an der FĆ¼hrungsplatte befestigt.The movable guide plate can also be arranged below the guide plate. In this embodiment, it is expedient if the first return element is provided in the guide groove. The guide plate usually has an end facing the dispensing opening and an end facing away from the dispensing opening. The axle is typically secured to the guide plate at the end facing the delivery port.

In einer Weiterbildung umfasst die FĆ¼hrungsplatte eine Tragachse. Die Tragachse liegt zumindest in einer Position der Achse auf einer der beiden SeitenwƤnde auf. Die Tragachse ist in der Regel an dem der Ausgabeƶffnung abgewandten Ende der FĆ¼hrungsplatte befestigt. Beim Drehen der Achse in der FĆ¼hrungsnut wird die Tragachse typischerweise von der Seitenwand weg geschwenkt. Bei einer Verschiebung der Achse in der FĆ¼hrungsnut liegt die Tragachse typischerweise auf einer oder auf beiden SeitenwƤnden auf.In a development, the guide plate comprises a support shaft. The support shaft rests on at least one position of the axis on one of the two side walls. The support shaft is usually attached to the discharge opening facing away from the end of the guide plate. As the axle rotates in the guide groove, the axle is typically pivoted away from the sidewall. In a displacement of the axis in the guide groove, the support shaft is typically on one or both side walls.

Auf einer Seite der FĆ¼hrungsnut kann eine optische Sendeeinheit vorgesehen sein. AuƟerdem kann die Achse Reflexions- oder Transmissionsmittel aufweisen, wobei der erste Sensor und/oder der zweite Sensor ein elektrooptischer Sensor ist zum Erkennen eines von der optischen Sendeeinheit gesandten und durch die Achse durchgelassenen oder durch die Achse reflektierten optischen Signals. Bei einer Verschiebung der Achse in der FĆ¼hrungsnut kann zum Beispiel das optische Signal durch die Achse blockiert oder durchgelassen oder reflektiert werden, wodurch der erste Sensor die jeweilige Position der Achse in der FĆ¼hrungsnut zu detektieren vermag. Analog kann bei einer Drehung der Achse das optische Signal durch die Achse reflektiert oder durchgelassen oder abgeblockt werden, so dass der zweite Sensor die jeweilige Drehstellung zu detektieren vermag.On one side of the guide groove, an optical transmitting unit may be provided. In addition, the axis may comprise reflection or transmission means, wherein the first sensor and / or the second sensor is an electro-optical sensor for detecting an optical signal sent by the optical transmission unit and transmitted through the axis or reflected by the axis. Upon displacement of the axis in the guide groove, for example, the optical signal can be blocked or transmitted or reflected by the axis, whereby the first sensor is able to detect the respective position of the axis in the guide groove. Similarly, upon rotation of the axis, the optical signal can be reflected or transmitted through the axis or blocked, so that the second sensor is able to detect the respective rotational position.

In einer Weiterbildung umfasst die Achse zumindest eine Markierung, welche durch den ersten Sensor und/oder den zweiten Sensor detektierbar ist. Die Markierung auf der Achse kann zum Beispiel eine bestimmte Magnetisierung der Achse sein. Bei einer Verschiebung oder einer Drehung der Achse Ƥndert sich somit ein Magnetfeld in der NƤhe der Achse und dies kann dann durch einen elektromagnetischen Sensor detektiert werden. Die Markierung kann zum Beispiel auch durch einen Vorsprung ausgebildet sein. Bei Drehung oder Verschiebung der Achse lƶst der Vorsprung ein Signal des ersten oder des zweiten Sensors aus. In diesem Fall kann der Sensor z.B. ein mechanischer Schalter oder ein optischer Sensor sein. Die Achse kann einen teilzylindrischen Bereich und einen abgeflachten Bereich umfassen, wobei der abgeflachte Bereich oder der Vorsprung an den teilzylindrischen Bereich angrenzt.In one development, the axis comprises at least one marking which can be detected by the first sensor and / or the second sensor. The mark on the axis may be, for example, a certain magnetization of the axis. With a displacement or rotation of the axis, a magnetic field thus changes in the vicinity of the axis and this can then be detected by an electromagnetic sensor. The marking may for example also be formed by a projection. Upon rotation or displacement of the axis, the projection triggers a signal of the first or the second sensor. In this case, the sensor may be e.g. a mechanical switch or an optical sensor. The axis may include a part-cylindrical portion and a flattened portion, with the flattened portion or protrusion adjacent to the part-cylindrical portion.

Mit der Erfindung wird auch ein Drucker mit einer Druckeinrichtung zum Bedrucken eines Blattes und einer Papierschneideeinrichtung bereitgestellt. Der Drucker weist vorzugsweise eine Papierausgabeeinrichtung der zuvor beschriebenen Art auf, wobei die Papierschneideeinrichtung zwischen der Druckeinrichtung und der Papierausgabeeinrichtung angeordnet ist. Der erste Sensor und/oder der zweite Sensor kann mit einer Auswerte- und Steuereinheit verbunden sein. Die Auswerte- und Steuereinheit kann das vom Sensor erfasste Signal auswerten und beurteilen, ob ein Papierstau oder eine vorzeitige Papierentnahme vorliegt. Gegebenenfalls schickt dann die Auswerte- und Steuereinheit ein entsprechendes Signal an die Druckeinrichtung und/oder die Papierschneideeinrichtung, wodurch der Druckvorgang beendet und/oder das Papier abgeschnitten wird. Hierdurch kann vermieden werden, dass es zu bleibenden SchƤden des Druckers, der Druckeinrichtung, der Schneideeinrichtung oder der Papierausgabeeinrichtung kommt.The invention also provides a printer with a printing device for printing a sheet and a paper cutter. The printer preferably has a paper delivery device of the type described above, the paper cutting device being arranged between the printing device and the paper delivery device. The first sensor and / or the second sensor may be connected to an evaluation and control unit. The evaluation and control unit can evaluate the signal detected by the sensor and assess whether there is a paper jam or a premature paper removal. If appropriate, then the evaluation and control unit sends a corresponding signal to the printing device and / or the paper cutter, whereby the printing process is terminated and / or the paper is cut off. This can be avoided that it comes to lasting damage to the printer, the printing device, the cutting device or the paper output device.

Im Folgenden wird auf die Figuren 1A bis 1C verwiesen. Die Figuren 1A bis C zeigen schematische Darstellungen eines LƤngsschnitts eines Druckers 1 eines Selbstbedienungsautomaten. Der Drucker 1 umfasst eine Papierausgabeeinrichtung 2, eine Druckeinrichtung 3 zum Bedrucken eines Blattes, eine Papierschneideeinrichtung 4 zum Schneiden eines Blattes und eine Ausgabeƶffnung 5, wobei die Papierausgabeeinrichtung 2 zwischen der Ausgabeƶffnung 5 und der Papierschneideeinrichtung 4 angeordnet ist und die Druckeinrichtung 3 vor der Papierschneideeinrichtung 4 angeordnet ist. Die Druckeinrichtung 3 umfasst eine Walze 6 sowie Mittel zum Bedrucken eines Blattes 7. Im AusfĆ¼hrungsbeispiel wird das Papier 7 mittels einer thermischen Druckers (Thermodrucker) bedruckt. Das zu bedruckende Papier 7 befindet sich auf einer Papierrolle 8, welche drehbar um eine Achse 9 gelagert ist. In Fƶrderrichtung gelangt das Papier 7 von der Papierrolle 8 zunƤchst zur Druckeinrichtung 3, wo es bedruckt und von der Walze 6 weiter gefƶrdert wird. Dann gelangt es Ć¼ber die Papierschneideeinrichtung 4 zur Papierausgabeeinrichtung 2.The following is on the FIGS. 1A to 1C directed.

The paper to be printed 7 is located on a paper roll 8, which is rotatably mounted about an axis 9. In the conveying direction, the paper 7 from the paper roll 8 first passes to the printing device 3, where it is printed and further promoted by the roller 6. Then it passes through the paper cutter 4 to the paper dispenser 2.

Die Papierausgabeeinrichtung 2 umfasst eine Ausgabeƶffnung 5 zum Entnehmen eines bedruckten Blattes und eine bewegliche FĆ¼hrungsplatte 10 zum FĆ¼hren des Blattes zur Ausgabeƶffnung 5. Die FĆ¼hrungsplatte 10 ist im LƤngsschnitt im Wesentlichen gerade. Sie kann in anderen AusfĆ¼hrungsbeispielen im LƤngsschnitt auch geschwungen, zum Beispiel S-fƶrmig sein. An der FĆ¼hrungsplatte 10 sind eine Achse 11 sowie eine Tragachse 12 befestigt. Sowohl die Achse 11 als auch die Tragachse 12 sind im Wesentlichen zylindrisch ausgebildet. Der beweglichen FĆ¼hrungsplatte 10 liegt eine feststehende, an einem GehƤuse 15 der Papierausgabeeinrichtung 2 befestigte Leitplatte 13 gegenĆ¼ber. In der Figur 1A sind die bewegliche FĆ¼hrungsplatte 10 und die Leitplatte 13 im Wesentlichen parallel zueinander angeordnet. Die FĆ¼hrungsplatte 10 und die Leitplatte 13 bilden einen Papierfƶrderkanal 14, der eine Papierfƶrderung in Richtung der Ausgabeƶffnung 5 erlaubt. Der Papierfƶrderkanal 14 verlƤuft etwa von der Papierschneideeinrichtung 4 schrƤg in Richtung der Ausgabeƶffnung 5. Die Leitplatte 13 ist starr mit dem GehƤuse 15 verbunden. Weiter sind die FĆ¼hrungsplatte 10 und die Leitplatte 13 seitlich durch zwei SeitenwƤnde 16 begrenzt, in denen jeweils eine FĆ¼hrungsnut 17 ausgebildet ist. Eine LƤngsrichtung der FĆ¼hrungsnut 17 erstreckt sich etwa in vertikaler Richtung (y-Richtung). Die FĆ¼hrungsnut 17 ist in den Figuren 2 bis 4 nƤher gezeigt.The paper output device 2 comprises a discharge opening 5 for removing a printed sheet and a movable guide plate 10 for guiding the sheet to the discharge opening 5. The guide plate 10 is substantially straight in longitudinal section. It can also be curved in other embodiments in longitudinal section, for example, be S-shaped. On the guide plate 10, an axle 11 and a support shaft 12 are attached. Both the axis 11 and the support shaft 12 are formed substantially cylindrical. The movable guide plate 10 is opposed to a fixed, attached to a housing 15 of the paper dispenser 2 guide plate 13. In the Figure 1A the movable guide plate 10 and the guide plate 13 are arranged substantially parallel to each other. The guide plate 10 and the guide plate 13 form a paper feed channel 14, a paper conveyor allowed in the direction of the discharge opening 5. The paper feed channel 14 extends approximately from the paper cutter 4 obliquely in the direction of the discharge opening 5. The guide plate 13 is rigidly connected to the housing 15. Further, the guide plate 10 and the guide plate 13 are laterally delimited by two side walls 16, in each of which a guide groove 17 is formed. A longitudinal direction of the guide groove 17 extends approximately in the vertical direction (y-direction). The guide groove 17 is in the FIGS. 2 to 4 shown closer.

Die Achse 11 ist in der FĆ¼hrungsnut 17 drehbar und verschiebbar gelagert, wobei eine vertikale Verschiebung der Achse 11 in der FĆ¼hrungsnut 17 durch einen ersten Sensor S1 detektierbar ist und eine Drehung der Achse 11 in der FĆ¼hrungsnut 17 durch einen zweiten Sensor S2 detektierbar ist. Die Achse 11 kann zumindest zwei vertikale Positionen in der FĆ¼hrungsnut 17 annehmen, wobei die Achse 11 zwischen diesen beiden Positionen in der FĆ¼hrungsnut 17 verschoben werden kann. AuƟerdem kann die Achse 11 zumindest zwei Drehstellungen annehmen, zwischen denen die Achse 11 gedreht werden kann. Eine Drehung der Achse 11 wird durch einen nicht gezeigten Anschlag begrenzt.The axis 11 is rotatably and slidably mounted in the guide groove 17, wherein a vertical displacement of the axis 11 in the guide groove 17 by a first sensor S1 is detectable and a rotation of the axis 11 in the guide groove 17 by a second sensor S2 can be detected. The axis 11 can assume at least two vertical positions in the guide groove 17, wherein the axis 11 can be moved between these two positions in the guide groove 17. In addition, the axis 11 can assume at least two rotational positions, between which the axis 11 can be rotated. A rotation of the axis 11 is limited by a stop, not shown.

In der FĆ¼hrungsnut 17 ist ein erstes RĆ¼ckstellelement 18 vorgesehen zum RĆ¼ckstellen der Achse 11 in eine erste Position in der FĆ¼hrungsnut 17. Die Achse 11 befindet sich in der Figur 1A in der genannten ersten Position. Weiterhin ist ein zweites RĆ¼ckstellelement 19 zum RĆ¼ckstellen der Achse 11 in eine bestimmte Drehstellung vorgesehen. Das zweite RĆ¼ckstellelement 19 ist an der beweglichen FĆ¼hrungsplatte 10 und dem GehƤuse 15 der Papierausgabeeinrichtung 2 befestigt. Das zweite RĆ¼ckstellelement 19 kann alternativ aber auch in der FĆ¼hrungsnut 17 vorgesehen sein. Eine erste Drehstellung der Achse 11 in der FĆ¼hrungsnut 17 ist in der Figur 1A gezeigt.In the guide groove 17, a first return element 18 is provided for returning the axle 11 to a first position in the guide groove 17. The axle 11 is located in the Figure 1A in the said first position. Furthermore, a second return element 19 is provided for returning the axle 11 in a specific rotational position. The second return member 19 is fixed to the movable guide plate 10 and the housing 15 of the paper delivery device 2. The second return element 19 may alternatively be provided in the guide groove 17, however. A first rotational position of the axis 11 in the guide groove 17 is in the Figure 1A shown.

Der erste Sensor S1 ist direkt an der FĆ¼hrungsnut 17 angeordnet. AuƟerdem ist der zweite Sensor S2 direkt an der FĆ¼hrungsnut 17 angeordnet. Die Sensoren S1, S2 sind mit einer Auswerte- und Steuereinheit 20 verbunden, welche wiederum mit der Druckeinrichtung 3 und der Papierschneideeinrichtung 4 verbunden ist. Die Auswerte- und Steuereinheit 20 ist dazu ausgestaltet, Signale der Sensoren S1, S2 auszuwerten und die Druckvorrichtung sowie die Papierschneidevorrichtung anzusteuern.The first sensor S1 is arranged directly on the guide groove 17. In addition, the second sensor S2 is arranged directly on the guide groove 17. The sensors S1, S2 are connected to an evaluation and control unit 20, which in turn is connected to the printing device 3 and the paper cutter 4. The evaluation and control unit 20 is configured to evaluate signals from the sensors S1, S2 and the printing device and the To control paper cutter.

In den Figuren 1A bis 1C ist die bewegliche FĆ¼hrungsplatte 10 oberhalb der Leitplatte 13 angeordnet. In alternativen AusfĆ¼hrungsformen kann die FĆ¼hrungsplatte 10 jedoch auch unterhalb der Leitplatte 13 angeordnet sein. Die Achse 11 ist an einem der Ausgabeƶffnung 5 zugewandten Ende der FĆ¼hrungsplatte 10 befestigt. Weiterhin ist die Tragachse 12 an einem der Papierschneideeinrichtung 4 zugewandten Ende der FĆ¼hrungsplatte 10 angeordnet und liegt in der Figur 1A auf den beiden SeitenwƤnden 16 auf. Es kann auch eine Ausnehmung in den SeitenwƤnden 16 vorgesehen sein, in die die Tragachse 12 eingesteckt ist. Wichtig ist lediglich, dass die Achse 11 sich ungestƶrt in LƤngsrichtung der FĆ¼hrungsnut 17 verschieben lƤsst und sich ungestƶrt in der FĆ¼hrungsnut 17 drehen lƤsst.In the FIGS. 1A to 1C the movable guide plate 10 is arranged above the guide plate 13. In alternative embodiments, however, the guide plate 10 may also be arranged below the guide plate 13. The axis 11 is fixed to one of the discharge opening 5 facing the end of the guide plate 10. Furthermore, the support shaft 12 is arranged on one of the paper cutter 4 facing the end of the guide plate 10 and is located in the Figure 1A on the two side walls 16. It may also be provided a recess in the side walls 16, in which the support shaft 12 is inserted. It is only important that the axis 11 can be moved undisturbed in the longitudinal direction of the guide groove 17 and rotate undisturbed in the guide groove 17.

Nachfolgend wird die Funktionsweise des gezeigten Druckers 1 erlƤutert. Nachdem ein Benutzer einen entsprechenden Befehl zum Drucken beispielsweise eines Kassenzettels, eines Steuerbelegs, eines Parkscheins, eines Fahrscheins, einer Quittung oder dergleichen in einen Selbstbedienungsautomaten eingegeben hat, dreht sich die Papierrolle 8 gegen Uhrzeigersinn und Papier 7 bewegt sich zur Druckeinrichtung 3. Das Papier 7 wird mittels der thermischen Druckeinrichtung 3 bedruckt und von der Walze 6 weiter Richtung Ausgabeƶffnung 5 gefƶrdert. Hierbei wird das Papier 7 zunƤchst zur Papierschneideeinrichtung 4 geleitet, wonach es Ć¼ber die Papierausgabeeinrichtung 2 zur Ausgabeƶffnung 5 gelangt. Wenn der Druckvorgang beendet ist, wird das Papier 7 durch die Papierschneideeinrichtung 4 zugeschnitten.Hereinafter, the operation of the illustrated printer 1 will be explained. After a user has entered a corresponding command to print, for example, a check slip, a tax bill, a parking ticket, a ticket, a receipt or the like in a self-service machine, the paper roll 8 rotates counterclockwise and paper 7 moves to the printing device 3. The paper. 7 is printed by means of the thermal printing device 3 and conveyed by the roller 6 further towards the discharge opening 5. Here, the paper 7 is first passed to the paper cutter 4, after which it passes through the paper delivery device 2 to the discharge opening 5. When the printing operation is finished, the paper 7 is cut by the paper cutter 4.

Bei der Ausgabeƶffnung 5 kann ein Benutzer das bedruckte Papier 7 entnehmen. Falls der Benutzer das Papier 7 aus der Ausgabeƶffnung 5 nimmt, bevor das Papier 7 vollstƤndig gedruckt ist, bzw. das Papier 7 durch die Papierschneideeinrichtung 4 geschnitten ist, wird eine Zugkraft auf das Papier 7 ausgeĆ¼bt. Die Zugkraft zeigt etwa in horizontaler Richtung (x-Richtung). Wegen der diagonalen Ausgestaltung des Fƶrderkanals wird eine Kraft in vertikaler Richtung (y-Richtung) auf die FĆ¼hrungsplatte 10 ausgeĆ¼bt und demzufolge verschiebt sich die Achse 11 in der FĆ¼hrungsnut 17 in eine zweite vertikale Position. Die zweite vertikale Position ist in der Figur 1B gezeigt. Der erste Sensor S1 detektiert nun, dass die Achse 11 sich nicht mehr in der ersten vertikalen Position sondern in der zweiten vertikalen Position befindet. Daraufhin schickt der erste Sensor S1 ein Signal zu einer Auswerte- und Steuereinheit 20. Die Auswerte- und Steuereinheit 20 wertet das vom ersten Sensor S1 gesandte Signal aus und schickt ein Signal zur Steuerung der Papierschneideeinrichtung 4 sowie der Druckeinrichtung 3. Die Druckeinrichtung 3 stoppt daraufhin den Druckvorgang und die Papierschneideeinrichtung 4 schneidet das Papier 7 ab. Hierdurch kƶnnen SchƤden an dem Drucker vermieden werden.At the discharge opening 5, a user can take out the printed paper 7. If the user removes the paper 7 from the discharge opening 5 before the paper 7 is completely printed, or the paper 7 is cut by the paper cutter 4, a tensile force is exerted on the paper 7. The tensile force points approximately in the horizontal direction (x-direction). Because of the diagonal design of the conveyor channel, a force in the vertical direction (y-direction) is exerted on the guide plate 10 and consequently shifts the axis 11 in the guide groove 17 in a second vertical position. The second vertical position is in the FIG. 1B shown. The first sensor S1 now detects that the axis 11 is no longer in the first vertical Position but in the second vertical position. The first sensor S1 then sends a signal to an evaluation and control unit 20. The evaluation and control unit 20 evaluates the signal sent by the first sensor S1 and sends a signal to control the paper cutting device 4 and the printing device 3. The printing device 3 then stops the printing operation and the paper cutter 4 cut off the paper 7. This can help prevent damage to the printer.

Neben der genannten vorzeitigen Papierentnahme kann es auch vorkommen, dass die Ausgabeƶffnung 5 blockiert wird. In diesem Fall staut sich Papier 7 zwischen der Leitplatte 13 und der FĆ¼hrungsplatte 10. Durch den Papierstau wird das Papier 7 im AusfĆ¼hrungsbeispiel nach oben gewƶlbt, wodurch sich die FĆ¼hrungsplatte 10 um die Achse 11 dreht. Dies ist in der Fig. 1C zu erkennen. Die Achse 11 wird somit in eine zweite Drehstellung gedreht, in der die Tragachse 12 nicht mehr auf den beiden SeitenwƤnden 16 aufliegt. Der zweite Sensor S2 detektiert die zweite Drehstellung und sendet ein entsprechendes Signal zur Auswerte- und Steuereinheit 20. Die Auswerte- und Steuereinheit 20 wiederum schickt ein Signal zur Druckeinrichtung 3 und zur Papierschneideeinrichtung 4, wonach die Papierschneideeinrichtung 4 das Papier 7 durchschneidet und die Druckeinrichtung 3 den Druckvorgang beendet. Falls die Blockade an der Ausgabeƶffnung 5 gelƶst ist, dreht sich die FĆ¼hrungsplatte 10 um die Achse 11 zurĆ¼ck in die erste Drehstellung. In den AusfĆ¼hrungsbeispielen der Figuren 1A bis 1C geschieht das ZurĆ¼ckdrehen in die erste Drehstellung durch die Schwerkraft. Um die Drehung zurĆ¼ck in die erste Drehstellung zu beschleunigen, ist das zweite als Feder ausgebildete RĆ¼ckstellelement 19 vorgesehen, welches dazu ausgebildet ist die FĆ¼hrungsplatte 10 in die erste Drehstellung zu bewegen. Aus dem gesagten ergibt sich also, dass alternativ auch auf das erste und das zweite RĆ¼ckstellelement 18, 19 verzichtet werden kann.In addition to the aforementioned premature paper removal, it may also happen that the discharge opening 5 is blocked. In this case, paper 7 accumulates between the guide plate 13 and the guide plate 10. The paper jam, the paper 7 is curved in the embodiment upwards, whereby the guide plate 10 rotates about the axis 11. This is in the Fig. 1C to recognize. The axle 11 is thus rotated in a second rotational position, in which the support shaft 12 no longer rests on the two side walls 16. The second sensor S2 detects the second rotational position and sends a corresponding signal to the evaluation and control unit 20. The evaluation and control unit 20 in turn sends a signal to the printing device 3 and the paper cutter 4, after which the paper cutter 4 cuts through the paper 7 and the printing device finished the printing process. If the blockage is released at the discharge opening 5, the guide plate 10 rotates about the axis 11 back into the first rotational position. In the embodiments of the FIGS. 1A to 1C Turning back to the first rotational position is done by gravity. To accelerate the rotation back into the first rotational position, the second formed as a spring restoring element 19 is provided which is adapted to move the guide plate 10 in the first rotational position. From what has been said, it follows that, alternatively, the first and the second restoring elements 18, 19 can also be dispensed with.

In den Figuren 2 bis 4 sind verschiedene Ausbildungen der Achse 11, der FĆ¼hrungsnut 17 und der Sensoren S1, S2 gezeigt. Die gezeigten AusfĆ¼hrungsformen kƶnnen allesamt im Drucker der Figuren 1A bis 1C verwendet werden.In the FIGS. 2 to 4 Various embodiments of the axis 11, the guide groove 17 and the sensors S1, S2 are shown. The embodiments shown may all be in the printer of FIGS. 1A to 1C be used.

Eine LƤngsrichtung der FĆ¼hrungsnut 17 in der Figur 2 ist parallel zur gezeigten y-Richtung. Die zylindrische Achse 11 lƤsst sich in LƤngsrichtung der FĆ¼hrungsnut 17 verschieben. Die Achse 11 umfasst zwei Bohrungen 21, 22, welche im Wesentlichen senkrecht zueinander ausgebildet sind. Sie kƶnnen optional auch einen anderen Winkel zueinander aufweisen, wobei der Winkel grĆ¶ĆŸer als 0Ā° und kleiner als 180Ā° sein sollte. Der erste Sensor S1 und der zweite Sensor S2 sind in der Figur 2 elektrooptische Sensoren. AuƟerdem sind eine erste optische Sendeeinheit 23 sowie eine zweite optische Sendeeinheit 24 vorgesehen. Die erste und die zweite optische Sendeeinheit 23, 24 senden stetig ein Signal in Richtung des ersten Sensors S1 bzw. des zweiten Sensors S2. In der gezeigten ersten vertikalen Position der Achse 11 in der FĆ¼hrungsnut 17 vermag der erste Sensor S1 kein Signal von der ersten optischen Sendeeinheit 23 zu detektieren. Bei einer Verschiebung der Achse 11 in vertikaler Richtung z.B. durch eine vorzeitige Papierentnahme wird die erste Bohrung 21 zusammen mit der Achse 11 nach oben in y-Richtung bewegt. Hierdurch kann ein optisches Signal von der ersten optischen Sendeeinheit 23 zum ersten Sensor S1 gelangen. Somit wird erkannt, dass sich die Achse 11 in der zweiten Position in der FĆ¼hrungsnut 17 befindet. Auch die zweite optische Sendeeinheit 24 schickt kontinuierlich ein Signal zum zweiten optischen Sensor S2. Im Gegensatz zum ersten optischen Sensor S1, empfƤngt der zweite optische Sensor S2 in der ersten Drehstellung stƤndig ein Signal. Bei Drehung der Achse 11 in der FĆ¼hrungsnut 17 in die zweite Drehstellung dreht sich auch die Bohrung 22, und folglich gelangt kein Signal mehr von der zweiten optischen Sendeeinheit 24 zum zweiten optischen Sensor S2. Hierdurch wird die zweite Drehstellung erkannt. Statt der Bohrungen 21, 22 kƶnnen auch z.B. Reflektionsmittel vorgesehen sein. Bei einer Drehung bzw. Verschiebung der Achse 11 in der FĆ¼hrungsnut 17 kƶnnen die Reflektionsmittel das optische Signal der optischen Sendeeinheit 23, 24 reflektieren. Alternativ wird durch eine Drehung bzw. Verschiebung der Achse 11 in der FĆ¼hrungsnut 17 verhindert, dass das optische Signal von der optischen Sendeeinheit 23, 24 reflektiert wird. Hierdurch kƶnnen die Drehstellung und die Position der Achse 11 in der FĆ¼hrungsnut 17 erkannt werden.A longitudinal direction of the guide groove 17 in the FIG. 2 is parallel to the y-direction shown. The cylindrical axis 11 can be in the longitudinal direction of the guide 17 move. The axis 11 comprises two bores 21, 22, which are formed substantially perpendicular to each other. Optionally, they may be at a different angle to each other, with the angle being greater than 0 Ā° and less than 180 Ā°. The first sensor S1 and the second sensor S2 are in the FIG. 2 electro-optical sensors. In addition, a first optical transmitting unit 23 and a second optical transmitting unit 24 are provided. The first and second optical transmitting units 23, 24 continuously send a signal in the direction of the first sensor S1 and the second sensor S2, respectively. In the illustrated first vertical position of the axis 11 in the guide groove 17, the first sensor S1 is unable to detect a signal from the first optical transmitting unit 23. In a displacement of the axis 11 in the vertical direction, for example by a premature paper removal, the first bore 21 is moved together with the axis 11 upwards in the y direction. As a result, an optical signal can pass from the first optical transmission unit 23 to the first sensor S1. Thus, it is recognized that the axle 11 is in the second position in the guide groove 17. The second optical transmission unit 24 also continuously sends a signal to the second optical sensor S2. In contrast to the first optical sensor S1, the second optical sensor S2 continuously receives a signal in the first rotational position. Upon rotation of the axis 11 in the guide groove 17 in the second rotational position, the bore 22 also rotates, and consequently no signal passes from the second optical transmitting unit 24 to the second optical sensor S2. As a result, the second rotational position is detected. Instead of the bores 21, 22, for example, reflection means can also be provided. Upon rotation or displacement of the axis 11 in the guide groove 17, the reflecting means can reflect the optical signal of the optical transmitting unit 23, 24. Alternatively, it is prevented by a rotation or displacement of the axis 11 in the guide groove 17, that the optical signal from the optical transmitting unit 23, 24 is reflected. As a result, the rotational position and the position of the axis 11 can be detected in the guide groove 17.

In der Figur 3 umfasst die Achse 11 einen teilzylindrischen Bereich 25 und einen abgeflachten Bereich 26, wobei der abgeflachte Bereich 25 an den teilzylindrischen Bereich 26 angrenzt. Bei einer vertikalen Verschiebung der Achse 11 in y-Richtung wird ein mechanischer Sensor S1 durch den abgeflachten Bereich 25 der Achse 11 ausgelƶst, wƤhrend bei einer Drehung der Achse 11 in der FĆ¼hrungsnut 17 ein mechanischer Sensor S2 ausgelƶst wird. In der FĆ¼hrungsnut 17 der Figuren 2 und 3 befindet sich ein nicht-dargestelltes erstes RĆ¼ckstellelement 18, zum RĆ¼ckstellen der Achse 11 in die erste vertikale Position.In the FIG. 3 the axis 11 comprises a part-cylindrical region 25 and a flattened region 26, the flattened region 25 being adjacent to the part-cylindrical region 26. In a vertical displacement of the axis 11 in the y-direction, a mechanical sensor S1 is triggered by the flattened portion 25 of the axis 11, while upon rotation of the axis eleventh in the guide groove 17, a mechanical sensor S2 is triggered. In the guide 17 of the FIGS. 2 and 3 There is a non-illustrated first return element 18, for returning the axle 11 in the first vertical position.

In der Ausgestaltung der Fig. 4 sind die Sensoren S1 und S2 induktive oder elektromagnetische Sensoren. Die Achse 11 umfasst einen Bereich 27 der magnetisiert ist. Bei Verschiebung der Achse 11 in y-Richtung Ƥndert sich das Magnetfeld in der NƤhe des Sensors S1 und bei Drehung der Achse 11 in der FĆ¼hrungsnut 17 Ƥndert sich das Magnetfeld in der NƤhe des Sensors S2. Durch die Sensoren S1 und S2 kann somit erkannt werden, in welcher Drehstellung oder in welcher vertikalen Position sich die Achse 11 befindet. Statt der magnetischen Markierung 27, wie sie in der Figur 4 gezeigt ist, kƶnnen auch andere Markierungen vorgesehen sein. Wichtig ist lediglich, dass die Markierung durch einen entsprechenden ersten Sensor S1 und/oder einen entsprechenden zweiten Sensor S2 detektierbar ist und dass die Markierung eine stƶrungsfreie Drehung bzw. Verschiebung der Achse 11 erlaubt. Um Sensoren S1 und S2 bzw. der ersten und den zweiten Sensor. In der Figur 4 ist das erste RĆ¼ckstellelement 18 in der FĆ¼hrungsnut 17 gezeigt.In the embodiment of Fig. 4 the sensors S1 and S2 are inductive or electromagnetic sensors. The axis 11 comprises a region 27 which is magnetized. Upon displacement of the axis 11 in the y-direction, the magnetic field changes in the vicinity of the sensor S1 and upon rotation of the axis 11 in the guide groove 17, the magnetic field changes in the vicinity of the sensor S2. By the sensors S1 and S2 can thus be detected in which rotational position or in which vertical position the axis 11 is located. Instead of the magnetic marking 27, as in the FIG. 4 is shown, other markings may be provided. It is only important that the marking can be detected by a corresponding first sensor S1 and / or a corresponding second sensor S2 and that the marking allows a trouble-free rotation or displacement of the axis 11. To sensors S1 and S2 or the first and the second sensor. In the FIG. 4 the first return element 18 is shown in the guide groove 17.
