Description

Die Erfindung betrifft eine Steuerung in einer Schreibmaschine der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a control in a typewriter of the type specified in the preamble of claim 1.

Die heute üblichen Schreibmaschinen weisen im Zeichentastenfeld eine Zeichenbelegung der Tasten auf, die weitgehend durch Vorschriften und Normen geregelt ist. Einem Bediener ist dadurch die Möglichkeit gegeben, bei einiger Erfahrung und Übung mühelos auf verschiedenen Maschinen zu schreiben, weil die Zeichen immer an der gleichen Stelle liegen und demzufolge keine erhöhte Aufmerksamkeit für das Auffinden der Zeichen eerforderlich ist. In anderen Ländern sind aber teilweise abweichende Vorschriften und Normen für die Belegung der Tastatur geschaffen worden, die zum einen Teil aus einer unterschiedlich häufigen Verwendung der Buchstaben des Alphabets in anderen Sprachen, zu einem anderen Teil aber auch aus dort verwendeten anderen Schriftzeichen resultieren. Das hat zur Folge, daß ein Bediener der einen Nationalität beim Schreiben auf Schreibmaschinen anderer Nationalität erhöhte Aufmerksamkeit aufwenden muß und unter Umständen bestimmte Zeichen auf der Tastatur gar nicht vorfindet. Doch auch dann schon, wenn ein Text in einer Fremdsprache geschrieben werden soll, fehlen vielfach die in der Fremdsprache eigenen besonderen Schriftzeichen.Today's typewriters in the character keypad have a character assignment of the keys, which is largely regulated by regulations and standards. This gives an operator the opportunity, with some experience and practice, to write effortlessly on different machines, because the characters are always in the same place and therefore no increased attention is required to find the characters. In other countries, however, deviating regulations and standards for the layout of the keyboard have been created, which partly result from the different uses of the letters of the alphabet in other languages, and partly from other characters used there. As a result, an operator of one nationality must pay increased attention when typing on typewriters of another nationality and may not find certain characters on the keyboard. But even if a text is to be written in a foreign language, the special characters that are special in the foreign language are often missing.

Die in heutigen Schreibmaschinen vielfach verwendeten Summentypenträger gestatten die Unterbringung einer Vielzahl verschiedenartiger Schriftzeichen, die den Zeichenvorrat einer genormten Tastatur übersteigen können. Darüberhinaus ist die Möglichkeit zu einer erheblichen Erweiterung des zum Abdruck zur Verfügung stehenden Zeichenvorrates dadurch gegeben, daß sich die Summentypenträger üblicherweise gegen solche mit einem anderen Zeichenvorrat austauschen lassen. Ein derart vergrößerter Zeichenvorrat ließ sich bisher aber nur mit einer erweiterten Tastatur bewältigen.The sum type carriers often used in today's typewriters allow a variety of different characters to be accommodated, which can exceed the character set of a standardized keyboard. In addition, there is the possibility of a considerable expansion of the character set available for printing by the fact that the sum type carriers can usually be exchanged for those with a different character set. So far, such an enlarged character set could only be managed with an extended keyboard.

Durch die US-A-3 927 752 ist ein Schriftsetzsystem mit einer standardmäßigen Schreibmaschinentastatur und einer zusätzlichen Hilfstastatur bekannt, über welche bei einer gedrückten Taste anderen Zeichen mit einer Taste der Schreibmaschinentastatur erzeugbar sind. Diese Hilfstasten sind wirkungsmäßig mit der bekannten Umschalttaste für die Groß-/Kleinschreibung vergleichbar. Hierdurch sind zwar auch Buchstaben einer anderen Sprache darstellbar, aber es sind keine Selektionseinrichtungen vorhanden, durch die die Maschine zunächst auf eine bestimmte Basistastatur und danach auf einen auswählbaren Schriftzeichensatz einstellbar ist. Aus der DE-A-26 27 698 ist eine Tastatur bekannt, auf die wahlweise unterschiedliche Gruppen von Symbolen schaltbar sind. Diese Symbolgruppen sind in einem Symbolspeicher abgespeichert und durch Betätigung einer besonderen Taste abrufbar.US-A-3 927 752 discloses a typesetting system with a standard typewriter keyboard and an additional auxiliary keyboard, by means of which other characters can be generated with a key on the typewriter keyboard when a key is pressed. These auxiliary keys are comparable in their effectiveness to the known shift key for upper / lower case. Letters of another language can also be represented in this way, but there are no selection devices by means of which the machine can first be set to a certain basic keyboard and then to a selectable character set. A keyboard is known from DE-A-26 27 698, to which different groups of symbols can optionally be switched. These symbol groups are stored in a symbol memory and can be called up by pressing a special key.

Weiterhin offenbart die FR-A-2 389 491 eine Datenstation für Datenverarbeitungsanlagen, bei der die Daten-Eingabetasten in mehreren Tastenblöcken angeordnet sind. Hierbei sind die Eingabetasten des einen Tasten-Blockes den Zeichen z. B. der englischen Sprache und ein weiterer Tasten-Block den speziellen Zeichen wenigstens einer anderen Sprache zugeordnet. Auch hier sind die oben angeführten Selektionseinrichtungen nicht bekannt.Furthermore, FR-A-2 389 491 discloses a data station for data processing systems, in which the data input keys are arranged in several key blocks. Here, the input keys of a key block are the characters z. B. the English language and another key block assigned the special characters at least one other language. The selection devices mentioned above are also not known here.

Der Erfindung liegt die Aufgabe zugrunde, eine Steuerung der eingangs genannten Art zu schaffen, mit der unter Verwendung einer Standardtastatur ein Schreiben mit unterschiedlichem Zeichenvorrat auf ein und derselben Maschine möglich ist.The invention has for its object to provide a controller of the type mentioned, with which using a standard keyboard, writing with different character sets on the same machine is possible.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Die Vorteile der Erfindung bestehen insbesondere darin, daß eine nach den nationalen Vorschriften eines Landes ausgelegte Tastatur durch Umschaltung den Anforderungen der nationalen Vorschriften eines anderen Landes angepaßt werden kann, wobei die Einstellung des Typenträgers auf die entsprechenden anderen Typen und erforderlichenfalls einer abweichenden Druckposition durchgeführt wird, wenn einer betätigten Taste eine andere Bedeutung zukommt. Durch Auswechseln des Typenträgers gegen einen solchen mit einem anderen Zeichenvorrat kann die Ausnutzuhg der Tastatur durch Mehrfachbelegung in Verbindung mit einer entsprechenden Selektion der dem Typenträger zugeordneten Belegung noch zusätzlich erweitert werden. Dadurch ist auch die Schaffung von Spezialtastaturen nicht nur für stark abweichende andere Sprachen sondern auch z. B. für mathematische oder wissenschaftliche Zwecke mit Sonderzeichenvorrat möglich.The advantages of the invention consist in particular in that a keyboard designed according to the national regulations of one country can be adapted by switching to the requirements of the national regulations of another country, the type carrier being set to the corresponding other types and, if necessary, a different printing position being carried out, if a key has a different meaning. By exchanging the type holder for one with a different set of characters, the use of the keyboard can be further expanded by multiple assignment in conjunction with a corresponding selection of the assignment assigned to the type holder. As a result, the creation of special keyboards is not only for strongly different other languages but also for. B. possible for mathematical or scientific purposes with special characters.

In einer besonderen Ausgestaltung der Erfin- dung können nach Selektion einer bestimmten Tastaturbelegung auf dem Typenträger nicht vorhandene Schriftzeichen durch Zusammensetzung vorhandener Schriftzeichen oder Schriftzeichenelemente erzeugt werden, wodurch eine noch weitergehende Anwendungsbreite der Tastatur und damit der ganzen Schreibmaschine gegeben ist, weil dadurch in vielen Fällen auf ein Austauschen des Typenträgers verzichtet werden kann.In a particular embodiment of it for domestic dung can be generated on the data carrier nonexistent characters by composing existing characters or character elements, creating an even more extensive range of applications the keyboard and around the typewriter is given to the selection of a particular keyboard layout because it in many In cases where the type carrier has to be replaced.

In einer weiteren vorteilhaften Ausgestaltung besteht die Möglichkeit, zwei getrennte Selektionen vorzunehmen, wobei z. B. zwischen einer nur einmal oder zumindest nur äußerst selten vorzunehmenden Grundeinstellung und einer häufiger zu verändernden Einstellung unterschieden werden kann. Eine solche getrennte Einstellmöglichkeit ist z. B. dann nützlich, wenn die gleiche Maschine mit verschiedenen Basistastaturen ausgerüstet werden kann, die abweichende Zeichenbelegungen der Tasten aufweisen, bei denen dann aber zumindest ein Teil der Tasten eine mehrfache Zeichenbelegung aufweist. Durch die erste Selektionsmöglichkeit kann dann die Maschine auf die Zeichenaufteilung der verwendeten Basistastatur eingestellt werden, während mit der zweiten Selektionseinrichtung z. B. der Schriftzeichensatz für die spanische, die griechische, die französische, die dänische oder deutsche Sprache ausgewählt werden kann.In a further advantageous embodiment, there is the possibility of making two separate selections. B. can be distinguished between a basic setting to be carried out only once or at least only extremely rarely and a setting that is to be changed more frequently. Such a separate setting is such. B. useful if the same machine can be equipped with different basic keyboards that have different character assignments of the keys, but in which at least some of the keys then have multiple character assignments. Through the first selection option, the machine can then be set to the character distribution of the basic keyboard used, while with the second selection device z. B. the font for the Spanish, Greek, French, Danish or German language can be selected.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen sowie dem nachfolgend anhand der Figuren beschriebenen Ausführungsbeispiel. Es zeigen

  • Figur 1 ein Blockschaltbild und
  • Figur 2 einen Ausschnitt aus einem Tastenfeld.
Further advantageous refinements of the invention result from the subclaims and the exemplary embodiment described below with reference to the figures. Show it
  • Figure 1 is a block diagram and
  • Figure 2 shows a section of a keypad.

Die schematische Darstellung der Figur 1 zeigt die zum Verständnis der Erfindung erforderlichen Bauteile als Blockschaltbild. Dargestellt sind eine Zeichen- und Funktionstastatur 1, ein Druckwerk 2, einen die Steuerung der Maschinenfunktionen durchführenden Mikrocomputer 9, einen Zeichengenerator 27 sowie eine über eine Steckaufnahme 29 der Maschine angeschlossene externe Baugruppe 28. Alle genannten Baugruppen stehen über eine Sammelleitung 10 miteinander in leitender Verbindung, über die Daten, Adressen und Steuersignale übertragen werden.The schematic representation of FIG. 1 shows the components required for understanding the invention as a block diagram. Shown are a character and function keyboard 1, a printing unit 2, a microcomputer 9 that controls the machine functions, a character generator 27 and an external assembly 28 connected via a plug-in receptacle 29 of the machine , over which data, addresses and control signals are transmitted.

Der Mikrocomputer 9 weist in an sich bekannter und deshalb nicht näher dargestellter Weise eine zentrale Steuereinheit, Programm- und Datenspeicher sowie Ein- und Ausgabeschaltungen auf, über die die Tastatur 1 und das Druckwerk 2 angeschlossen sind. Der Speicher 11 ist in eine Vielzahl von Speicherbereichen aufgeteilt, deren jeder einen Codewandler 12 bis 26 beinhaltet. Sowohl der Speicher 11 als auch der Zeichengenerator 27 brauchen keine selbständigen Baugruppen zu sein sondern können statt dessen in den Speichern des Mikrocomputers 9 enthalten sein. Das Druckwerk 2 weist eine Typenscheibe als Summentypenträger 3 auf, deren auf radialen Lamellen angeordnete Drucktypen durch Drehung der Typenscheibe in Richtung des Pfeiles 6 in die Druckposition einstellbar sind. Durch horizontale Verschiebung der Typenscheibe in Richtung des Pfeiles 7 erfolgt die spaltenweise Einstellung der Druckposition, während durch Verschiebung des Aufzeichnungsträgers 4 in Richtung des Pfeiles 8 die zeilenweise Einstellung der Druckposition möglich ist. Der Abdruck einer eingestellten Drucktype erfolgt durch einen an sich bekannten Abschlagmagneten. Die Verschiebung des Aufzeichnungsträgers 4, des Typenträgers 3 in horizontaler Richtung und die Dreheinstellung des Typenträgers werden von Positionierantrieben vorgenommen, die zusammen mit einer zugehörigen Ansteuerschaltung durch den Block 5 symbolisiert sind.The microcomputer 9 has, in a manner known per se and therefore not shown in detail, a central control unit, program and data memory and input and output circuits via which the keyboard 1 and the printing unit 2 are connected. The memory 11 is divided into a plurality of memory areas, each of which contains a code converter 12 to 26. Both the memory 11 and the character generator 27 do not need to be independent assemblies but can instead be contained in the memories of the microcomputer 9. The printing unit 2 has a type disk as a total type carrier 3, the printing types arranged on radial lamellae of which can be adjusted into the printing position by rotating the type disk in the direction of the arrow 6. By horizontally shifting the type plate in the direction of arrow 7, the column-wise setting of the printing position takes place, while by shifting the recording medium 4 in the direction of arrow 8, the row-wise setting of the printing position is possible. A set print type is imprinted by a knock-off magnet known per se. The displacement of the record carrier 4, the type carrier 3 in the horizontal direction and the rotary setting of the type carrier are carried out by positioning drives, which are symbolized by block 5 together with an associated control circuit.

Das Tastenfeld der Zeichen- und Funktionstastatur 1 wird von einer Basistastatur in bekanntem Aufbau und mit bekannter, standardisierter Zeichenbelegung gebildet, wie insbesondere im linken Teil der Figur 2 zu sehen ist. Die im rechten Teil des Tastenfeldes liegenden Tasten sind jeweils mehrfach mit Zeichen belegt, von denen die meisten in den Sprachen anderer Länder benötigt werden. Betätigung einer dieser Tasten kann also den Abdruck eines der auf dem Tastenkopf abgebildeten Zeichen zur Folge haben, abhängig von einer Selektion, die nachfolgend noch näher erläutert wird.The keypad of the character and function keyboard 1 is formed by a basic keyboard in a known structure and with a known, standardized character assignment, as can be seen in particular in the left part of FIG. The keys in the right part of the keypad are each assigned multiple characters, most of which are required in the languages of other countries. Pressing one of these keys can therefore result in the imprint of one of the characters depicted on the key top, depending on a selection which is explained in more detail below.

Die Betätigung einer der Tasten der Tastatur 1 hat zur Folge, daß ein der Taste zugeordnetes Codesignal über den Mikrocomputer 9 an einen der Codewandler 12 bis 26 des Speichers 11 gelangt, der das Codesignal in Signale zur Einstellung des Typenträgers 3 sowie der Druckposition gegenüber dem Aufzeichnungsträger 4 wandelt. Diese Einstellsignale gelangen über den Mikrocomputer 9, der in allen Fällen die zeitliche und von anderen Funktionen abhängige Steuerung durchführt, an die Ansteuerschaltung und die Positionierantriebe 5 des Druckwerkes 2, so daß Einstellung und Abdruck vorgenommen werden können.The actuation of one of the keys of the keyboard 1 has the result that a code signal assigned to the key arrives via the microcomputer 9 at one of the code converters 12 to 26 of the memory 11, which converts the code signal into signals for setting the type carrier 3 and the printing position relative to the recording medium 4 converts. These setting signals are sent to the control circuit and the positioning drives 5 of the printing unit 2 via the microcomputer 9, which carries out the time-dependent and other functions-dependent control in all cases, so that setting and printing can be carried out.

Auf der Tastatur 1 ist weiterhin ein Schiebeschalter als Selektionseinrichtung 30 vorgesehen, der eine von fünf Einstellpositionen 31 bis 35 einnehmen kann. Das der jeweils eingenommenen Einstellposition 31 bis 35 entsprechende Ausgangssignal bewirkt, daß einer der fünf Codewandler 12 bis 16 der ersten Reihe, 17 bis 21 der zweiten Reihe oder 22 bis 26 der dritten Reihe ausgewählt und der Tastatur zugeordnet wird. So mag z. B. die Einstellposition 31 der französischen Sprache zugeordnet sein, wobei die Einstellung des Schiebeschalters auf die Einstellposition 31 die Zuordnung eines Codewandlers 12, 17, 22 im Speicher 11 zu der Tastatur zu Folge hat, durch den bei Betätigung einer mehrfach belegten Zeichentaste das einer französischen Tastaturbelegung entsprechende Zeichen im Druckwerk 2 eingestellt und zum Abdruck gebracht wird. Gegebenenfalls erforderliche Schrittunterdrückungen, Zeilenschaltbewegungen o. ä. werden dabei ebenfalls berücksichtigt.On the keyboard 1, a slide switch is also provided as a selection device 30, which can assume one of five setting positions 31 to 35. The output signal corresponding to the respective setting position 31 to 35 causes one of the five code converters 12 to 16 of the first row, 17 to 21 of the second row or 22 to 26 of the third row to be selected and assigned to the keyboard. So z. B. the setting position 31 may be assigned to the French language, the setting of the slide switch to the setting position 31 resulting in the assignment of a code converter 12, 17, 22 in the memory 11 to the keyboard, by pressing a multi-assigned character key that of a French one Corresponding characters in the keyboard layout are set in printing unit 2 and printed. Any necessary step suppression, line switching movements or similar are also taken into account.

Einstellung der Selektionseinrichtung 30 (Schiebeschalter) auf eine andere der Einstellpositionen 31 bis 35 bewirkt in entsprechender Weise eine Zuordnung zu einem anderen, einer anderen Sprache zugeordneten Codewandler 12 bis 16 der ersten Reihe, 17 bis 21 der zweiten Reihe oder 22 bis 26 der dritten Reihe, wobei die dieser anderen Sprache entsprechenden Zeichen der mehrfach belegten Tasten abdruckbar sind.Setting the selection device 30 (slide switch) to a different one of the setting positions 31 to 35 results in a corresponding assignment to another code converter 12 to 16 assigned to a different language in the first row, 17 to 21 in the second row or 22 to 26 in the third row , wherein the characters corresponding to this other language of the multi-assigned keys can be printed.

Auf der Tastatur 1 ist eine weitere Selektionseinrichtung 36 (Schiebeschalter) angeordnet, die ebenfalls mehrere Einstellpositionen 37 bis 39 aufweist. Durch Einstellung dieser Selektionseinrichtung auf eine der Einstellpositionen 37 bis 39 ist jeweils eine der drei Codewandler-Reihen 12 bis 16, 17 bis 21, 22 bis 26 im Speicher 11 vorauswählbar. Dadurch ist eine Zuordnung unterschiedlicher Codewandler für den Zeichenvorrat unterschiedlicher Sprachen unter Berücksichtigung verschiedener in einer solchen Maschine einsetzbarer Basistastaturen möglich. Gegenüber der in Figur 2 dargestellten Tastenbelegung einer Basistastatur erster Art sind auch solche anderer Art verwendbar, bei denen die Tasten - auch die nicht mehrfach belegten Tasten - eine andere Zeichenaufteilung aufweisen. Das macht es aber erforderlich, für jede verwendbare Basistastatur einen anderen Satz an Codewandlern für jede einstellbare Sprache vorzusehen. Da im vorliegenden Ausführungsbeispiel die Möglichkeit zur Verwendung dreier Basistastaturen vorgesehen ist, weist somit die Selektionseinrichtung 36 drei Einstellpositionen 37 bis 39 und der Speicher 11 drei Codewandlergruppen 12 bis 16,17 bis 21 und 22 bis 26 zu je fünf Codewandlern auf. Je nach Einstellung der Selektionseinrichtung 36 wird demnach eine Einstellung der Selektionseinrichtung 30 einen Codewandler aus der ersten, der zweiten oder der dritten Gruppe für die eingestellte Sprache auswählen.A further selection device 36 (slide switch) is arranged on the keyboard 1 and also has a plurality of setting positions 37 to 39. By setting this selection device to one of the setting positions 37 to 39, one of the three code converter rows 12 to 16, 17 to 21, 22 to 26 can be preselected in the memory 11. This makes it possible to assign different code converters for the character set in different languages, taking into account various basic keyboards that can be used in such a machine. Compared to the key assignment of a basic keyboard of the first type shown in FIG. 2, those of a different type can also be used in which the keys - even the keys that are not assigned multiple times - are different Character division. However, this makes it necessary to provide a different set of code converters for each adjustable language for each basic keyboard that can be used. Since the possibility of using three basic keyboards is provided in the present exemplary embodiment, the selection device 36 thus has three setting positions 37 to 39 and the memory 11 has three code converter groups 12 to 16, 17 to 21 and 22 to 26, each with five code converters. Depending on the setting of the selection device 36, a setting of the selection device 30 will accordingly select a code converter from the first, the second or the third group for the set language.

Obgleich der Codewandler 36 hier als Bestandteil der Tastatur 1 dargestellt ist, wird er üblicherweise getrennt davon unter der Maschinenbekleidung angeordnet sein, weil seine Einstellung im Regelfall nur erstmalig bei der Ausrüstung der Maschine oder zu einem späteren Zeitpunkt bei einer Umrüstung von einem technischen Fachmann und nicht vom Bediener vorgenommen werden wird. Die Einstellpositionen 31 bis 35 der ersten Selektionseinrichtung 30 können zweckmäßigerweise mit unterschiedlichen Farben gekennzeichnet sein, so daß bei einer entsprechenden farblichen Darstellung der jeweils zugehörigen Zeichen auf den mehrfach belegten Zeichentasten die Orientierung für den Bediener vereinfacht ist.Although the code converter 36 is shown here as part of the keyboard 1, it will usually be arranged separately from it under the machine clothing, because its setting is usually only for the first time when the machine is equipped or at a later point in time when it is converted by a technical expert and not will be done by the operator. The setting positions 31 to 35 of the first selection device 30 can expediently be marked with different colors, so that the orientation for the operator is simplified with a corresponding color representation of the respectively associated characters on the multiply assigned character keys.

Einige Sprachen, wie z. B. die griechische Sprache weisen eine solche Anzahl andersartiger Zeichen auf, daß die Unterbringung aller Zeichen auf einem üblichen Summentypenträger 3 nicht mehr möglich ist. Um das sehr lästige Wechseln des Typenträgers 3 während der Erstellung von Schriftstücken zu vermeiden, ist ein Zeichengenerator 27 vorgesehen, dessen Ausgangssignale das Abdrucken zusammengesetzter Zeichen steuern. Der einer solchen Sprache zugeordnete Codewandler (z. B. der Codewandler 26 bei einer Einstellung der Selektionseinrichtung 30 auf die Einstellposition 35 und der Selektionseinrichtung 36 auf die Einstellposition 39) liefert bei Betätigung einer Taste für ein zusammenzusetzendes Zeichen seine Ausgangsinformation an den Zeichengenerator 27, der daraus die erforderlichen Einstellsignale für ein zwei- oder mehrmaliges Einstellen des Typenträgers auf die abzudruckenden Teilzeichen sowie die erforderlichen Einstellsignale für spaltenweise und/oder zeilenweise Veränderung der Abdruckposition bzw. Unterdrückung einer Einstellbewegung an die Ansteuerschaltung und die Positionierantriebe 5 des Druckwerkes 2 liefert. Aufgrund dieser Einstellsignale werden nacheinander alle zu dem vollständigen Zeichen gehörenden Teilzeichen positionsgerecht abgedruckt. Der Typenträger 3 kann dabei so ausgestattet sein, daß Zeichenelemente für das Zusammensetzen von Zeichen vorgesehen sind oder daß Zeichen aus zwei oder mehreren für sich ebenfalls aussagefähigen Zeichen zusammengesetzt werden. Ausgangsinformationen des Codewandlers 26, die nichtzusammenzusetzende Zeichen betreffen, werden direkt über den Mikrocomputer 9 dem Druckwerk 2 zugeführt.Some languages, such as B. the Greek language have such a number of different types of characters that it is no longer possible to accommodate all of the characters on a standard sum type carrier 3. In order to avoid the very annoying change of type carrier 3 during the creation of documents, a character generator 27 is provided, the output signals of which control the printing of composed characters. The code converter assigned to such a language (e.g. the code converter 26 when the selection device 30 is set to the setting position 35 and the selection device 36 to the setting position 39) supplies its output information to the character generator 27 when a key is pressed for a character to be combined it supplies the necessary setting signals for a two or more settings of the type carrier to the partial characters to be printed, as well as the required setting signals for column and / or row-by-row change of the printing position or suppression of an adjustment movement to the control circuit and the positioning drives 5 of the printing unit 2. On the basis of these setting signals, all the partial characters belonging to the complete character are successively printed in the correct position. The type support 3 can be equipped in such a way that character elements are provided for the composition of characters or that characters are composed of two or more characters that are also meaningful. Output information from the code converter 26, which relates to characters that are not to be composed, are fed directly to the printing unit 2 via the microcomputer 9.

Die Maschine weist außerdem eine Steckaufnahme 29 auf, über die eine mit weiteren Codewandlern versehene steckbare Baugruppe 28 angeschlossen werden kann. Zur Auswahl von Codewandlern auf dieser Baugruppe können die Selektionseinrichtungen 30 und 36 mit weiteren - gestrichelt dargestellten - Einstellpositionen versehen sein, so daß die Variationsmöglichkeiten noch vergrößert werden können. Dazu kann von besonderem Nutzen sein, wenn der Summentypenträger 3 gegen einen solchen mit zusätzlichen oder anderen Schriftzeichen auswechselbar ist.The machine also has a plug-in receptacle 29, via which a plug-in module 28 provided with further code converters can be connected. To select code converters on this assembly, the selection devices 30 and 36 can be provided with further setting positions, shown in dashed lines, so that the possible variations can be increased still further. This can be particularly useful if the sum type carrier 3 can be exchanged for one with additional or different characters.

Statt der als Schiebeschalter ausgebildeten Selektionseinrichtungen 30, 36 können natürlich auch andere Einstellelemente, z. B. Tasten eines eigenen Tastenfeldes eingesetzt werden. Grundsätzlich ist es auch möglich, statt der Anordnung von Codewandlern in einem maschineninternen Speicher diese bedarfsweise von einem externen Speicher in einen Datenspeicher der Maschine zu laden, wodurch eventuell auf besondere Selektionseinrichtungen verzichtet werden kann. Es ist auch denkbar, alle Codewandler auf steckbaren Baugruppen anzuordnen, so daß die Maschine durch über eine der Steckaufnahme 29 entsprechende Schnittstelle jeweils mit dem für eine ausgewählte Sprache zutreffenden Codewandler verbunden ist.Instead of the selection devices 30, 36 designed as a slide switch, other setting elements, for. B. Keys of a separate keypad can be used. In principle, it is also possible, instead of arranging code converters in an internal machine memory, to load them from an external memory into a data memory of the machine, as a result of which special selection devices can possibly be dispensed with. It is also conceivable to arrange all code converters on plug-in modules so that the machine is connected to the code converter applicable to a selected language via an interface corresponding to the plug-in receptacle 29.
