Stand der TechnikState of the art

Ein Drucker der vorstehend genannten Art ist beispielsweise aus der EP B 0 195 949 bekannt. Er dient beispielsweise als Kassendrucker mit je einer Druckstation für Bon/Journal und Beleg. Bei dem bekannten Drucker kann jeweils das ganze Drucksystem an einer Druckstation, welches außer dem Druckkopf auch das Druckwiderlager, die Transport- und Führungsmittel für den Zeilenvorschub und gegebenenfalls auch die Farbträgereinrichtung umfaßt, als austauschbare Baugruppe ausgebildet sein. Dies gibt die Möglichkeit, den Drucker in seiner Grundausstattung in großen Stückzahlen herzustellen, wobei die Ausstattung der verschiedenen Druckstationen nach Wunsch des Kunden jederzeit bis unmittelbar vor Auslieferung individuell festgelegt werden kann. Darüber hinaus hat der Kunde auch die Möglichkeit, selbst einzelne Druckstationen von einem Druckverfahren auf ein anderes umzustellen, ohne einen vollkommen neuen Drucker kaufen zu müssen. Der Wechsel von einem Druckverfahren auf ein anderes erfordert aber, wie oben bereits gesagt, den Austausch der gesamten Baugruppe. A printer of the above type is for example known from EP B 0 195 949. For example, it serves as POS printer with one printing station each for receipt / journal and Receipt. In the known printer can do the whole Printing system at a printing station, which besides that Printhead also the print abutment, the means of transport and guidance for the line feed and if necessary also the ink carrier device comprises, as an exchangeable assembly be trained. This gives the opportunity Basic printers in large quantities manufacture, the equipment of the various Printing stations at any time up to the customer's request can be determined individually before delivery. In addition, the customer also has the opportunity to do so himself individual printing stations from one printing process to one switch to another without a completely new printer to have to buy. The change from a printing process to another, however, as already mentioned above, requires that Exchange of the entire assembly.

Aus der DE OS 2 232 590 ist ferner ein Drucker mit einem parallel zu einem Druckwiderlager verfahrbaren Wagen bekannt, auf den wahlweise unterschiedliche Druckköpfe aufgesteckt werden können.From DE OS 2 232 590 a printer with a known carriage movable parallel to a pressure abutment, on which different printheads can be attached can be.

In der EP A 0 623 471 ist ein Tintenstrahldrucker mit einer Druckstation beschrieben, bei dem jeweils unterschiedliche Druckfarben enthaltende Druckköpfe auf einem Wagen angeordnet sind. Die Druckköpfe dienen dem Druck auf ein und denselben Aufzeichnungsträger.In EP A 0 623 471 there is an ink jet printer with a Printing station described, each with different Printheads containing printing inks arranged on a carriage are. The print heads are used to print on one and the same Recording medium.

Aus der EP A 0 359 580 ist ein Drucker mit zwei Druckstationen bekannt, deren jede einen parallel zu einem Druckwiderlager verstellbar geführten Wagen aufweist. An jedem Wagen ist eine wagenfeste Druckkopfaufnahme vorgesehen, die ihrerseits jeweils sechs Halterungen für sechs Einzeldraht-Druckköpfe enthält. Die Druckrichtungen der Druckstationen sind senkrecht zueinander ausgerichtet.EP A 0 359 580 describes a printer with two printing stations known, each one parallel to a pressure abutment adjustable carriage has. On every car a carriage-fixed printhead holder is provided, which in turn, six brackets for six single-wire printheads contains. The printing directions of the printing stations are aligned perpendicular to each other.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen Drucker der eingangs genannten Art anzugeben, bei dem die beiden Druckstationen wenig Raum beanspruchen und auf einfachste Weise von einem Druckverfahren auf ein anderes umgestellt werden können.The invention has for its object a printer Specify the type mentioned, in which the two printing stations take up little space and in the simplest way be switched from one printing process to another can.

Diese Aufgabe wird für einen Drucker, der einen Wagen mit zwei wagenfesten Druckkopfaufnahmen mit Halterungsmitteln zur lösbaren Halterung je eines Druckkopfes hat, durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. This task is for a printer who is using a carriage two carriage-fixed printhead receptacles with mounting devices for releasable mounting of a printhead, through which characterizing features of claim 1 solved.

Die Anordnung beider Druckkopfaufnahmen an ein und demselben Wagen ermöglicht eine raumsparende Anordnung der beiden Druckstationen in dem Drucker. Für den Übergang von einem Druckverfahren zu einem anderen innerhalb einer Druckstation muß lediglich der Druckkopf selbst ausgetauscht werden.The arrangement of both printhead receptacles on one and the same Trolley enables a space-saving arrangement of the two Print stations in the printer. For the transition from one Printing process to another within a printing station only the print head itself has to be replaced.

Die jeweilige Druckkopfaufnahme ist für eine erste Art von Druckkopf ausgebildet und mit einem Druckkopfadapter verbindbar, der seinerseits zur Aufnahme eines Druckkopfes einer anderen Art ausgebildet ist. Für das Auswechseln des Druckkopfes braucht man also lediglich den Druckkopf der ersten Art durch den mit dem Druckkopf einer anderen Drucktechnologie verbundenen Adapter zu ersetzen. Besonders einfach gestaltet sich dabei die Gestaltung der Druckkopfaufnahme und der Auswechselvorgang, wenn der Druckkopfadapter mit der Druckkopfaufnahme durch die Halterungsmittel an der letzteren verbindbar ist, wenn also der Adapter an seinem der Druckkopfaufnahme zugewandten Ende in der gleichen Weise ausgestaltet ist, wie der Druckkopf der zum direkten Einsetzen in die Druckkopfaufnahme bestimmten Art.The respective printhead holder is for a first type of Printhead designed and connectable with a printhead adapter, which in turn for receiving a printhead is of a different kind. For changing the So you only need the printhead first type through the one with the printhead other adapters connected to other printing technology. The design of the Printhead recording and the replacement process when the Printhead adapter with the printhead holder through the holder is connectable to the latter, i.e. if the Adapter at its end facing the printhead receptacle is designed in the same way as the print head of the for direct insertion into the printhead holder Art.

Das Auswechseln des Druckkopfes gestaltet sich besonders einfach, wenn die Halterungsmittel als Rastmittel ausgebildet sind, so daß das Auswechseln der Druckköpfe ohne die Hilfe von Werkzeugen erfolgen kann.The replacement of the printhead is particularly easy easy if the holding means are designed as locking means are so that replacing the printheads without the Tools can be done.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Druckers ist die Druckkopfaufnahme jeweils für die Halterung eines Tintendruckkopfes ausgebildet, während der Druckkopfadapter zur Aufnahme eines Nadeldruckkopfes ausgebildet ist. Je nachdem, ob man einfache Blätter bedrucken oder beispielsweise für Belege Durchschreibesätze drucken will, können entweder an beiden Druckstationen Tintendruckköpfe oder an einer Druckstation ein Tintendruckkopf und an der anderen Druckstation ein Nadeldruckkopf verwendet werden.In a preferred embodiment of the invention Printer is the printhead holder for the bracket an ink print head formed during the Printhead adapter designed to accommodate a needle printhead is. Depending on whether you can print on simple sheets or, for example, print carbonless records for receipts can either use ink printheads at both printing stations or an ink printhead at a printing station and on a needle printhead can be used in the other printing station.

Für das gleichzeitige Drucken von Bons und Belegen ist es besonders vorteilhaft, wenn die Druckkopfaufnahmen derart an dem Wagen angeordnet sind, daß die Druckrichtung der in ihnen aufgenommenen Druckköpfe senkrecht aufeinanderstehen.It is for simultaneous printing of receipts and receipts particularly advantageous if the printhead recordings are such are arranged on the carriage that the printing direction of the in the printheads they have received are perpendicular to each other.

Vorzugsweise werden beide Druckstationen über die gleiche Steuervorrichtung angesteuert, wobei dann zweckmäßigerweise auf dem Wagen eine mit der Steuervorrichtung verbundene Verteilerschaltung angeordnet ist, die einen Anschluß für jeden Druckkopf hat. Beim Auswechseln der Druckköpfe muß also der jeweilige Druckkopf lediglich mit dem richtigen Anschluß der Verteilerschaltung verbunden werden.Preferably, both printing stations are the same Controlled control device, then expediently on the carriage one connected to the control device Distribution circuit is arranged, which has a connection for has every printhead. When replacing the printheads So the respective printhead only with the correct one Connection of the distribution circuit can be connected.

Beschreibung einer Ausführungsform der ErfindungDescription of an embodiment of the invention

In Figur 1 ist mit 10 die Basis eines Druckergestells bezeichnet, oberhalb der zwei sich senkrecht zur Bildebene erstreckende Führungsstangen 12, 14 angeordnet sind, auf denen ein Wagen 16 verschiebbar geführt ist. Der Wagen 16 umfaßt zwei zueinander senkrecht gerichtete Schenkel 18 und 20 und wird durch einen nicht dargestellten Motor auf den Führungsstangen 12 und 14 in Längsrichtung derselben bewegt.In FIG. 1, 10 denotes the base of a printer frame, above the two are perpendicular to the image plane extending guide rods 12, 14 are arranged on which a carriage 16 is slidably guided. The car 16 comprises two mutually perpendicular legs 18 and 20 and is driven by a motor, not shown Guide rods 12 and 14 moved in the longitudinal direction thereof.

Die Schenkel 18 und 20 tragen jeweils eine plattenförmige Druckkopfaufnahme 22, die zur Aufnahme eines Tintendruckkopfes 24 bestimmt ist und die in Figur 3 näher dargestellt ist. An der einen Schmalseite der rechteckigen plattenförmigen Druckkopfaufnahme 22 befinden sich zwei Klauen 26, die zum Übergreifen einer Leiste oder zweier Ansätze 28 an dem quaderförmigen Gehäuse des Tintendruckkopfes 24 bestimmt sind. An der gegenüberliegenden Schmalseite ist ein Haken 30 ausgebildet, der in Richtung des Doppelpfeiles A in Figur 3 elastisch auslenkbar ist und vorzugsweise ebenso wie die Klauen 26 einstückig mit der Druckkopfaufnahme 22 ausgebildet ist. Er dient dazu, eine an dem Gehäuse des Tintendruckkopfes 24 vorgesehen Leiste 32 (Figur 2) zu übergreifen, wenn der Tintendruckkopf 24 in die Druckkopfaufnahme 22 eingesetzt wird. Das Einsetzen des Tintendruckkopfes 24 in die Druckkopfaufnahme 22 geschieht in der Weise, daß der Tintendruckkopf 24 zunächst mit den Ansätzen 28 unter die Klauen 26 geschoben wird und anschließend auf die plattenförmige Druckkopfaufnahme 22 gedrückt wird, wobei der Haken 30 zunächst durch die Leiste 32 an dem Tintendruckkopf 24 ausgelenkt wird und anschließend über die Leiste 32 schnappt. Zum Lösen des Tintendruckkopfes 24 von der Druckkopfaufnahme 22 muß zunächst der Haken 30 wieder in Öffnungsrichtung ausgelenkt werden, worauf der Tintendruckkopf 24 von der Druckkopfaufnahme 22 abgehoben werden kann.The legs 18 and 20 each carry a plate-shaped Print head receptacle 22, which is used to hold an ink print head 24 is determined and shown in more detail in Figure 3 is. On one narrow side of the rectangular plate-shaped Printhead receptacle 22 there are two claws 26, to overlap a bar or two lugs 28 the cuboid housing of the ink print head 24 determined are. On the opposite narrow side is a Hook 30 formed in the direction of the double arrow A is deflectable elastically in FIG. 3 and preferably likewise like the claws 26 in one piece with the printhead receptacle 22 is trained. It is used to attach one to the housing of the Ink print head 24 provided bar 32 (Figure 2) too spill over when the ink printhead 24 is in the printhead receptacle 22 is used. Inserting the ink printhead 24 in the printhead receptacle 22 happens in the Way that the ink print head 24 initially with the approaches 28 is pushed under the claws 26 and then on the plate-shaped printhead receptacle 22 is pressed, whereby the hook 30 first through the bar 32 on the ink print head 24 is deflected and then over the Bar 32 snaps. To release the ink print head 24 from the print head receptacle 22 must first the hook 30 again be deflected in the opening direction, whereupon the ink print head 24 are lifted off the printhead receptacle 22 can.

In Figur 1 sind zwei Tintendruckköpfe 24 auf den beiden Druckkopf aufnahmen 22 montiert und weisen jeweils mit einem Mundstück 34 zu einem Druckwiderlager 36 hin. Druckkopf 24 und Druckwiderlager 36 bilden jeweils eine Druckstation. Die in der Figur 1 dargestellte obere Druckstation, in der der Tintendruckkopf 24 mit horizontaler Druckrichtung angeordnet ist, dient zum Ausdrucken beispielsweise eines Bons und/oder Journals auf einen bandförmigen Aufzeichnungsträger 38, der von einer Vorratsrolle 40 abgezogen wird, die in dem Druckergestell in nicht dargestellter Weise gelagert ist. Die andere Druckstation, in welcher der Tintendruckkopf 24 mit vertikaler Druckrichtung angeordnet ist, dient zum Bedrucken von Belegen 42, die auf der horizontalen Druckträgerauflagefläche 44 der Basis 10 mit Hilfe von Transportrollenpaaren 46 eingezogen, ausgeworfen und während des Druckvorganges transportiert werden können.In Figure 1 there are two ink printheads 24 on the two Printhead recordings 22 mounted and each have a Mouthpiece 34 to a pressure abutment 36. Printhead 24 and pressure abutment 36 each form a printing station. The upper printing station shown in Figure 1, in the the ink print head 24 is arranged with a horizontal printing direction is used to print out a receipt, for example and / or journals on a tape-shaped record carrier 38, which is drawn off from a supply roll 40, the stored in the printer frame in a manner not shown is. The other printing station, in which the ink printhead 24 is arranged with the vertical printing direction, serves for printing receipts 42 on the horizontal Print carrier support surface 44 of the base 10 with the aid of Feed roller pairs 46 drawn, ejected and during of the printing process can be transported.

Sollen beispielsweise Belege mit Durchschlag bedruckt werden, so ist dies mit einem Tintendruckkopf 24 nicht möglich. Hierzu eignet sich aber ein Nadeldruckkopf, der in den Druckstationen der Figur 1 gestrichelt angedeutet und mit 48 bezeichnet ist. Zum Befestigen des Nadeldruckkopfes 48 an dem Wagen 16 dient ein in Figur 3 dargestellter Adapter 50. Der Adapter hat die Form einer rechteckigen Platte, die ebenso wie das Gehäuse des Tintendruckkopfes 24 an einer Schmalseite den Ansätzen oder der Leiste 28 entsprechende Ansätze 52 und an der entgegengesetzten Schmalseite eine Leiste 54 hat. Mit den Ansätzen 52 wird der Adapter 50 unter die Klauen 26 der Druckkopfaufnahme 22 geschoben. Anschließend wird der Adapter 50 gegen die Druckkopfaufnahme 22 gedrückt, bis der Haken 30 über der Leiste 54 einschnappt. Das Lösen des Adapters 50 von der Druckkopfaufnahme 22 geschieht in der gleichen Weise, wie dies für den Tintendruckkopf 24 beschrieben wurde.If, for example, receipts are to be printed with a copy, this is not possible with an ink print head 24. A needle printhead, which is in the printing stations of Figure 1 and dashed lines is designated 48. For attaching the needle print head 48 on the carriage 16 is an adapter shown in Figure 3 50. The adapter is in the form of a rectangular plate, the same as the housing of the ink printhead 24 on one Narrow side corresponding to the approaches or the strip 28 Approaches 52 and on the opposite narrow side has a ledge 54. With the lugs 52, the adapter 50 slid under the claws 26 of the printhead receptacle 22. Subsequently the adapter 50 against the printhead receptacle 22 pressed until the hook 30 snaps over the bar 54. Detaching the adapter 50 from the printhead receptacle 22 happens in the same way as for the Ink printhead 24 has been described.

Auf seiner Oberseite hat der Adapter 50 zwei Lagerklötze 56, zwischen denen ein in Figur 3 nur mit seinem Mundstück 58 dargestellter Nadeldruckkopf 48 montiert werden kann. Hierzu sind an dem Mundstück 58 flügelförmige Flansche 60 ausgebildet, die jeweils eine Bohrung 62 haben, durch die eine Schraube 64 in eine in dem jeweiligen Lagerklotz 56 ausgebildete Gewindebohrung 66 eingreift.The adapter 50 has two bearing blocks on its upper side 56, between which one in Figure 3 only with his mouthpiece 58 shown needle printhead 48 can be mounted. For this purpose, wing-shaped flanges 60 are on the mouthpiece 58 formed, each having a bore 62 through which a screw 64 in one in the respective bearing block 56 trained threaded bore 66 engages.

Der Drucker enthält eine in Figur 4 schematisch dargestellte steuervorrichtung 67, die über ein Flexband, d.h. ein Flachbandkabel oder eine flexible Leiterplatte 68 mit einer Verteilerschaltung oder -platine 70 verbunden ist, die in nicht dargestellter Weise an dem Wagen 16 befestigt ist. Das Flexband 68 umfaßt Stromversorgungsleitungen und Steuerleitungen. Von der Verteilerschaltung 70 gehen jeweils Anschlüsse 72 für die Tintenköpfe 24 bzw. Anschlüsse 74 für die Nadeldruckköpfe 48 aus. Ein Anschluß 72 für einen Tintendruckkopf 24 umfaßt einen an der Druckkopfaufnahme 22 angeordneten Kontaktabschnitt 76 mit Einzelkontakten 78, die mit entsprechenden nicht dargestellten Gegenkontakten an der Unterseite des in Figur 2 dargestellten Tintendruckkopfes 24 in Kontakt treten können, wenn der Tintendruckkopf 24 in die Druckkopfaufnahme 22 eingesetzt wird.The printer contains one shown schematically in FIG control device 67, which is operated via a flexible band, i.e. a ribbon cable or a flexible circuit board 68 with a distributor circuit or board 70 is connected, attached to the carriage 16 in a manner not shown is. Flexband 68 includes power lines and Control lines. Go from the distribution circuit 70 each Ports 72 for the ink heads 24 or ports 74 for the needle printheads 48. A connection 72 for one Ink printhead 24 includes one on the printhead receptacle 22 arranged contact section 76 with individual contacts 78, with corresponding counter contacts, not shown at the bottom of that shown in Figure 2 Ink printhead 24 can contact when the Ink printhead 24 inserted into the printhead receptacle 22 becomes.

Der Anschluß 74 für den jeweiligen Nadeldruckkopf endet in einem mehrpoligen Stecker 80, der in einen entsprechenden Gegenstecker 82 am Nadeldruckkopf eingesteckt werden kann.The connection 74 for the respective needle print head ends in a multi-pin connector 80, which in a corresponding Mating connector 82 can be inserted into the needle print head.

Die Leiterbahnen zur Stromversorgung sind für alle Köpfe bestimmt. Die Steuerleitungen sind den Anschlüssen der jeweiligen Köpfe zugeordnet. Damit die Anzahl der Leitungen im Flexband 68 nicht zu groß wird, können auf der Verteilerplatine Schalter vorgesehen sein, die bei Montage zweier gleicher Köpfe dafür sorgen, daß nur der jeweils angesteuerte Kopf aktiviert wird. Es ist dann nur möglich, alternativ auf Bon/Journal oder Beleg zu drucken. Im anderen Fall, wenn ein Tintenkopf und ein Nadelkopf betrieben werden, wäre es dagegen möglich, parallel auf den beiden Druckstationen zu arbeiten.The conductor tracks for the power supply are for all heads certainly. The control lines are the connections of the respective Heads assigned. So the number of lines in the Flexband 68 is not too large, can on the distribution board Switches can be provided when two are installed same heads ensure that only the one being controlled Head is activated. It is then only possible as an alternative to print on receipt / journal or receipt. In the other Case when an ink head and a needle head are operated, on the other hand, it would be possible to run in parallel on the two Printing stations to work.

Wie die vorstehende Beschreibung zeigt, können die Druckköpfe auf sehr einfache Weise ausgewechselt werden, wobei jede mögliche Kombination zweier unterschiedlicher Druckköpfe in den beiden Druckerstationen vorgesehen sein kann.As the description above shows, the printheads can can be replaced in a very simple way, whereby any possible combination of two different printheads can be provided in the two printer stations.
