Description

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

Es ist bekannt, einen Summentypenträger, insbesondere eine mit Typenstegen versehene Typenscheibe, in einer Kassette anzuordnen (siehe DE-A-2803433), mit der dieselbe zwischen einer Einstellvorrichtung mit einem Hammerwerk und einem Druckwiderlager in das Druckwerk einsetzbar und wieder herausnehmbar ist, und zwar bei dem hier dargestellten Ausführungsbeispiel so, daß die Typenscheibe auch während des Betriebes in der Kassette verbleibt, d. h., daß die Typenscheibe innerhalb der Kassette mit einer maschineninternen Dreheinstellwelle verbunden werden muß.It is known to arrange a sum type carrier, in particular a type disc provided with type crosspieces, in a cassette (see DE-A-2803433), with which the same can be inserted into and removed from the printing unit between an adjusting device with a hammer mechanism and a pressure abutment in the embodiment shown here so that the type plate remains in the cassette even during operation, i. that is, the type plate within the cassette must be connected to an internal rotary adjustment shaft.

Diese Einrichtung kann die ihr zugrundeliegende Aufgabe, wonach die Typenscheibe während eines Austausches gegen Beschädigung und der Bediener beim Austauschen einer benutzten Typenscheibe gegen verschmutzte Hände geschützt werden sollen, zufriedenstellend lösen, weshalb es auch angezeigt ist, eine solche Einrichtung in einer zweckmäßigen Ausgestaltung zum Einsatz zu bringen.This device can satisfactorily solve its underlying task, according to which the type plate should be protected against damage during an exchange and the operator should be protected against dirty hands when replacing a used type plate, which is why it is also appropriate to use such a device in a suitable embodiment bring.

Weiterhin ist durch die deutsche Patentschrift DE-B-2243204 bereits ein Druckwerk mit in Typenträgerkassetten befindlichen, kettenartigen Typenträgern bekanntgeworden, die auswechselbar sind und einen unterschiedlichen Zeichenvorrat aufweisen. Wird der Typenträger hierbei ausgewechselt, dann muß selbstverständlich auch die Anordnung zur Feststellung der gerade in Druckstellung befindlichen Drucktypen gewechselt werden.Furthermore, the German patent DE-B-2243204 has already made known a printing unit with chain-like type carriers located in type carrier cassettes, which are interchangeable and have a different character set. If the type carrier is replaced here, then of course the arrangement for determining the printing types currently in the printing position must also be changed.

Dieses bekannte Patent enthält aber lediglich eine Anordnung zur Feststellung der vor den Druckhämmern in Druckstellung befindlichen Typen des umlaufenden Typenträgers und gibt keine Hinweise, daß Steuerbefehle entsprechend der typographischen Schriftzeichenformen des verwendeten Drucktypensatzes an die Schrittschaltwerke für die Schrittschaltung in Schreib- und Zeilenrichtung, an die Steuervorrichtung für die Abdruckenergie des Druckhammers, an das Schaltglied für die Auswahl der Schreibrichtung in Rechts- oder Linkslauf, an die Steuervorrichtung für die selbsttätige Belegung der Tastatur mit Symbolen, etc., gegeben werden. Jede Schriftart erfordert nämlich unterschiedliche Zeilen- und Schreibschritte, unterschiedliche Druckenergien und z. B. eine unterschiedliche Belegung der Tastatur mit Symbolen, die den auf dem Typenträger vorgesehenen Drucktypen entsprechen. Einen Hinweis zur Steuerung dieser Funktionen beim Einsetzen der Wechselkassette in die Aufnahmevorrichtung enthält der Gegenstand des deutschen Patentes 2 243 204 nicht.However, this known patent only contains an arrangement for determining the types of the rotating type carrier which are in the printing position in front of the print hammers and does not give any indication that control commands corresponding to the typographic character forms of the print type set used are sent to the step switches for the step switching in the writing and line directions, to the control device for the impression energy of the print hammer, to the switching element for the selection of the writing direction in clockwise or counterclockwise rotation, to the control device for the automatic assignment of the keyboard with symbols, etc., are given. Each font requires different line and writing steps, different printing energies and z. B. a different assignment of the keyboard with symbols that correspond to the print types provided on the type support. The subject matter of German patent 2 243 204 does not contain any information on controlling these functions when inserting the exchangeable cassette into the receiving device.

Der Erfindung liegt die Aufgabe zugrunde, Schreibmaschinen mit Wechselkassetten konstruktiv so weiter zu bilden, daß das Wechseln der Kassetten durch die Bedienungsperson noch weiter vereinfacht wird.The invention has for its object to construct typewriters with exchangeable cartridges so that the replacement of the cartridges is made even easier by the operator.

Gelöst wird diese Aufgabe durch die in dem Kennzeichen des Patentanspruchs 1 angegebenen Mittel und deren Anordnungen.This object is achieved by the means specified in the characterizing part of patent claim 1 and their arrangements.

Den Gegenstand der Erfindung weiterbildende Merkmale sind in den Unteransprüchen und in Teilen der Beschreibung angegeben.Features of the subject of the invention are specified in the subclaims and in parts of the description.

Durch die Anordnung ausbrechbarer und als Steuermarken wirksamer Zinken oder Ronden, durch das Aufbringen von magnetischen Marken auf einer Folie oder durch das Vorsehen eines ein Programm enthaltenden elektronischen Speicherelementes an dem Aufnahmeteil für den Typenträger oder dem Deckel der Kassette können der im folgenden Büromaschine genannten Schreibmaschine, beim Einsetzen der Kassettenteile in die zugeordnete Aufnahmestelle, Steuerbefehle mitgeteilt werden, die sich z. B. auf den Drucktypensatz des sich in der Kassette befindlichen Typenträger beziehen.By arranging tines or round blanks which can be broken out and act as control marks, by applying magnetic marks on a film or by providing an electronic storage element containing a program on the receiving part for the type carrier or the cover of the cassette, the typewriter referred to below as office machine can when inserting the cassette parts into the assigned receiving point, control commands are communicated, which are z. B. refer to the print type set of the type carrier located in the cassette.

Diese Steuerbefehle können z. B. auf einen in der Büromaschine vorhandenen Prozessor derart einwirken, daß der Wagen der Maschine mit an die Schriftart des Drucktypensatzes angepaßten Zeilenschritten und Schreibschritten (z. B. 2,54 mm, 2,12 mm oder Proportional-Schrittabstände) angetrieben wird.These control commands can e.g. B. act on an existing processor in the office machine in such a way that the carriage of the machine is driven with line steps and writing steps (z. B. 2.54 mm, 2.12 mm or proportional step spacing) adapted to the font of the print type set.

Weiterhin kann der Büromaschine mit dem Gegenstand der Erfindung ein Programm vermittelt bzw. in derselben abgerufen werden, mit dem eine individuell auf jedes einzelne Schriftzeichen bezogene Abdruckenergie oder auch auf die auf eine bestimmte Schriftart bezogene Gesamtabdruckenergie für ein Hammerwerk einstellbar ist.Furthermore, the object of the invention can be used to convey or call up the office machine with a program with which an impression energy individually related to each individual character or also to the total impression energy related to a specific font can be set for a hammer mill.

Eine weitere Einsatzmöglichkeit des Erfindungsgegenstandes ergibt sich bei solchen Büromaschinen, die für verschiedene, unterschiedlichen Sprachgebieten zugeordnete Betriebsweisen umschaltbar ausgebildet werden sollen, z. B. zum Zweck der Änderung der Schreibrichtung von Rechtslauf in Linkslauf des Wagens.A further possible application of the subject matter of the invention arises in the case of office machines which are to be designed to be switchable for different operating modes assigned to different language areas, for. B. for the purpose of changing the writing direction from clockwise to counterclockwise rotation of the car.

Ein anderes Beispiel zur Anwendung des Erfindungsgegenstandes ist die beim Einsetzen eines Typenträgers in die Büromaschine selbsttätige Belegung der Tastatur mit Symbolen, die den auf dem Typenträger vorgesehenen Drucktypen entsprechen. Solche Tastaturen, bei denen die den einzelnen Tasten zugeordneten Symbole z. B. über optische Mittel verändert werden können, sind allgemein bekannt, weshalb hier auch nicht näher auf deren konstruktive Ausbildung eingegangen wird.Another example of the application of the subject matter of the invention is the automatic assignment of symbols to the keyboard when inserting a type holder into the office machine, which correspond to the printing types provided on the type holder. Such keyboards, in which the symbols assigned to the individual keys, for. B. can be changed via optical means are generally known, which is why here is not discussed in more detail on their design.

Ferner kann der Erfindungsgegenstand in dem Prozessor einer Büromaschine sogar ein auf einen Sondertypenträger bezogenes Programm abrufen, bzw. in denselben ein solches Einlesen, mit dem dann, z. B. durch die Betätigung nur einer Taste, eine Folge von nacheinander ablaufenden unterschiedlichen Typenabdruckvorgängen, beispielsweise zur Erstellung eines Benzol-Ringes beim Schreiben chemischer Formeln, ausgelöst werden kann.Furthermore, the subject of the invention can even call up a program related to a special type carrier in the processor of an office machine, or read in such a program, with which, for. B. by pressing only one button, a sequence of successive different type print processes, for example to create a benzene ring when writing chemical formulas.

Im einzelnen kann der Erfindungsgegenstand sogar so ausgebildet sein, daß die Aufnahmekassette als Steuermittel eine elektronische Baugruppe enthält, die als ein maschinenexternes Speicherelement (z. B. ein ROM) wirksam ist und nur ein Teilprogramm des gesamten Mikroprozessors enthalten kann, und die durch Einsetzen der Kassette in die Büromaschine über die dann als Verbindungsleitungen ausgebildeten Steuerglieder mit dem Prozessor verbunden wird. Zweckmäßig weist die Kassette bei einer so ausgestalteten Maschine nach der Erfindung aus Sicherheitsgründen zusätzlich noch ein z. B. mit einem maschineninternen Kontaktschalter zusammenwirkendes Steuermittel (Steuernase) auf, mittels dem dann der Mikroprozessor abschaltbar ist, bevor das maschinenexterne Speicherelement von dem Prozessor getrennt wird - oder umgekehrt, oder mittels dem die Betriebsbereitschaft der Büromaschine durch Unterbrechen des Betriebsstromes unterbrechbar ist.In particular, the subject matter of the invention can even be designed such that the recording cassette contains as control means an electronic assembly which acts as an external memory element (e.g. a ROM) and can only contain a partial program of the entire microprocessor, and which by inserting the Cassette in the office machine is connected to the processor via the control members then formed as connecting lines. The cassette expediently also has a z. B. with a machine-internal contact switch cooperating control means (control nose), by means of which the microprocessor can then be switched off before the machine-external memory element is separated from the processor - or vice versa, or by means of which the operational readiness of the office machine can be interrupted by interrupting the operating current.

Weiterhin hat es sich als zweckmäßig herausgestellt, den Deckel der Wechselkassette auch dann in ein Aufnahmeteil der Büromaschine mit dem Effekt der normalen Netzstromeinschaltung einzusetzen, wenn an dem Deckel keine Steuermarken oder Prüfmarken vorgesehen sind, da hierdurch dessen Verlierbarkeit beseitigbar ist.Furthermore, it has proven to be expedient to insert the lid of the interchangeable cassette into a receiving part of the office machine with the effect of normal mains power on when no control marks or test marks are provided on the cover, since this makes it impossible to lose it.

In den Zeichnungen sind verschiedene Ausführungsbeispiele der Erfindung dargestellt, die nachfolgend im einzelnen beschrieben sind. Es zeigt

Various exemplary embodiments of the invention are shown in the drawings and are described in detail below. It shows
  • 1 is a diagrammatic representation of an embodiment,
  • Fig. 2 shows a detail of Fig. 1 and
  • 3 and 4 another embodiment of a type carrier cassette according to the invention,
  • Fig. 5 is a diagrammatic, highly schematic representation of an office machine according to the invention and
  • Fig. 6 further arrangements on the type carrier cassette.

Wie die Fig. 1 aufzeigt, kann eine Wechselkassette 1, in der ständig eine mit einzelnen Typenstegen 2 versehene Typenscheibe 3 (siehe auch Fig.4) angeordnet ist, aus einem Aufnahmeteil 4 für die Typenscheibe 3 und einem Deckel 5 bestehen. Der auf das Aufnahmeteil 4 aufsteckbare Deckel 5, der im montierten Zustand des Aufnahmeteiles 4 und somit auch der Typenscheibe 3 in Aufnahmemitteln der Büromaschine 6 (siehe Fig. 5) jedoch von dem Aufnahmeteil 4 abgezogen wird, ist ebenfalls in Aufnahmemitteln der Büromaschine 6 einsteckbar, die hier aus einem eine Aufnahmeausnehmung 7 bildenden Einsteckschacht 8 bestehen. Dieser Einsteckschacht 8 kann ein von dem einschiebbaren Deckel 5 betätigbares Schaltelement 9 aufweisen, das z. B. ein im Betriebsstromkreis der Büromaschine angeordneter Schaltkontakt ist.As shown in FIG. 1, an interchangeable cassette 1, in which a type plate 3 (see also FIG. 4) with individual type bars 2 is constantly arranged, can consist of a receiving part 4 for the type plate 3 and a cover 5. The cover 5 which can be plugged onto the receiving part 4, but which is removed from the receiving part 4 in the mounting state of the receiving part 4 and thus also the type plate 3 in receiving means of the office machine 6 (see FIG. 5), can also be inserted into receiving means of the office machine 6, which consist here of an insertion slot 8 forming a receiving recess 7. This slot 8 can have an actuatable by the insertable cover 5 switching element 9, the z. B. is a switching contact arranged in the operating circuit of the office machine.

Ein solches, z. B. mit einem Netzschalter 12 in Reihe angeordnetes Schaltelement 9 kann jedoch auch in den aus einem Einsteckschacht 10 bestehenden Aufnahmemitteln für das Aufnahmeteil 4 der Wechselkassette 1 vorgesehen sein, das dann von einer als Steuermittel für die Betriebsstromeinschaltung wirksamen und an dem Aufnahmeteil 4 vorgesehenen Steuernase 11 (siehe Fig. 1) betätigbar ist.Such, e.g. B. with a power switch 12 arranged in series switching element 9 can also be provided in the existing from a slot 10 receiving means for the receiving part 4 of the exchangeable cassette 1, which is then effective as a control means for switching on the operating current and provided on the receiving part 4 control nose 11th (see Fig. 1) can be actuated.

Wie die Fig. 1 und 2 zeigen, können an dem Aufnahmeteil 4 der Wechselkassette 1 eine Reihe von Steuermarken 13 vorgesehen sein, die als Steuermittel zum Beeinflussen von in der Büromaschine angeordneten Steuergliedern 14 dienen. Diese nicht näher dargestellten Steuerglieder 14 sind im unteren Bereich 15 des Einsteckschachtes 10 vorgesehen und bestehen im Zusammenhang mit der in der Fig. 1 dargestellten Wechselkassette 1 aus elektrischen Kontaktelementen.As shown in FIGS. 1 and 2, a number of control marks 13 can be provided on the receiving part 4 of the exchangeable cassette 1 and serve as control means for influencing control elements 14 arranged in the office machine. These control elements 14, not shown in more detail, are provided in the lower region 15 of the insertion shaft 10 and, in connection with the interchangeable cassette 1 shown in FIG. 1, consist of electrical contact elements.

Die als Steuermittel wirksamen Steuermarken 13 bestehen aus mit dem Aufnahmeteil 4 materialgleich verbundenen, durch Sollbruchstellen 16 einzeln ausbrechbaren Zinken, mittels denen von der Wechselkassette 1 durch die als Abfrageglieder wirksamen Steuerglieder 14 z. B. ein binär codiertes Signal für einen in der Büromaschine vorgesehenen und nicht näher dargestellten Mikroprozessor oder zur unmittelbaren Ansteuerung von Funktionssteuereinrichtungen derselben abfragbar ist.The control marks 13 which act as control means consist of tines which are connected to the receiving part 4 in the same material and which can be broken out individually by predetermined breaking points 16, by means of which tines can be removed from the exchangeable cassette 1 by the control elements 14 which act as interrogation members. B. a binary coded signal for a provided in the office machine and not shown microprocessor or for direct control of function control devices of the same can be queried.

Wie die Fig. 3 und 4 aufzeigen, können die als Steuermittel wirksamen Steuermarken 13a auch an dem zugehörigen Deckel 5a der Wechselkassette 1a vorgesehen sein und aus über Sollbruchstellen 16a einzeln ausbrechbaren Ronden bestehen. In diesem Falle müssen, wie auch die Fig. 5 aufzeigt, die Steuerglieder 14a natürlich im unmittelbaren Bereich der durch den Einsteckschacht 8 gebildeten Aufnahmemittel für den Deckel 5a vorgesehen sein. Die Steuerglieder 14a können hier als aus Fotodioden und Fototransistoren bestehende optische Abfühlglieder ausgebildet sein.As shown in FIGS. 3 and 4, the control marks 13a which act as control means can also be provided on the associated cover 5a of the exchangeable cassette 1a and consist of blanks which can be broken out individually via predetermined breaking points 16a. In this case, as FIG. 5 also shows, the control members 14a must of course be provided in the immediate area of the receiving means for the cover 5a formed by the insertion shaft 8. The control elements 14a can be designed here as optical sensing elements consisting of photodiodes and phototransistors.

Um sicherstellen zu können, daß der Deckel 5a der Wechselkassette seitenrichtig in den Einsteckschacht 8 eingeführt wird, ist derselbe in seinem Querschnitt T-förmig ausgeführt, und der Deckel 5a weist an seitlichen Längskanten 17, in der Einsteckrichtung gesehen, unsymmetrische Vorsprünge 18 auf.In order to be able to ensure that the cover 5a of the exchangeable cassette is inserted into the insertion slot 8 with the correct side, the cross section of the latter is T-shaped, and the cover 5a has asymmetrical projections 18 on the longitudinal longitudinal edges 17, as seen in the insertion direction.

Wie die Fig. 3 und 4 weiter aufzeigen, kann an einem Teil der Wechselkassette 1, z. B. dem Deckel 5a, anstelle der entfernbaren Steuermarken eine Magnetfolie 19 befestigt sein, die dann z. B. mit einzelnen magnetisierbaren Feldern 20 die Steuermittel zum Beeinflussen der Steuerglieder bildet. Bei einer so ausgebildeten Wechselkassette bestehen die Steuerglieder dann entsprechend aus magnetisch beeinflußbaren Abfragemitteln, z. B. einem für eine Abfrage seitlich bewegbaren magnetischen Lesekopf, der allgemein bekannt und deshalb hier nicht näher dargestellt ist.3 and 4 show further, can on a part of the removable cassette 1, z. B. the lid 5a, instead of the removable tax stamps a magnetic film 19 can be attached, which then z. B. with individual magnetizable fields 20 forms the control means for influencing the control members. In such an exchangeable cassette, the control members then consist accordingly of magnetically influenceable interrogation means, e.g. B. a laterally movable magnetic reading head for a query, which is generally known and is therefore not shown here.

In der Fig. 6 ist ein weiteres Ausführungsbeispiel der Wechselkassette 1 dargestellt, bei dem in einem Teil derselben, z. B. in einem Ansatz 21 des Deckels 5b eine elektronische Baugruppe 22 vorgesehen ist, die aus einem Speicherchip, z. B. einem »ROM« besteht. Diese somit maschinenexterne elektronische Baugruppe kann ein Teilprogramm des maschineninternen Mikroprozessors enthalten. Die Baugruppe 22 ist an dem Deckel 5b elektrisch fest angeschlossen und ist über unempfindliche, z. B. an demselben aufgedruckte oder angeklebte elektrische Leiter 23 mit den als Gegenkontakte wirksamen Steuergliedern in den Aufnahmemitteln (Einsteckschacht) in Wirkverbindung bringbar.Another embodiment is shown in FIG game of the removable cassette 1 shown, in which in a part of the same, for. B. in an approach 21 of the lid 5b, an electronic assembly 22 is provided, which consists of a memory chip, for. B. there is a »ROM«. This electronic module, which is thus external to the machine, can contain a sub-program of the internal microprocessor. The assembly 22 is firmly connected to the cover 5b and is insensitive, for. B. on the same printed or glued electrical conductor 23 can be brought into operative connection with the control elements acting as counter-contacts in the receiving means (insertion shaft).

Weiterhin kann, wie ebenfalls in der Fig. 6 dargestellt, an dem Aufnahmeteil 4b eine Prüfeinrichtung vorgesehen sein, mittels der verhindert werden kann, daß einem mit einem bestimmten Drucktypensatz versehenen Typenträger 3b ein falscher Deckel 5b zugeordnet werden kann, der dann folglich auch mit dem Drucktypensatz nicht übereinstimmende Steuermarken 13b aufweisen würde. Diese Prüfeinrichtung besteht aus ebenfalls einzeln ausbrechbaren und in der Anzahl den Steuermarken 13b angepaßten Prüfmarken 25, die dann in einer solchen Kombination ausgebrochen werden, daß sie mit den Steuermitteln (Steuermarken 13b) für einen gegenseitigen Prüfeingriff korrespondieren können.Furthermore, as also shown in FIG. 6, a test device can be provided on the receiving part 4b, by means of which it can be prevented that a wrong cover 5b can be assigned to a type support 3b provided with a certain type of print type, which consequently also with the Print type set would have mismatched tax stamps 13b. This test device also consists of test marks 25 which can also be broken out individually and which are adapted in number to the control marks 13b, which are then broken out in such a combination that they can correspond to the control means (control marks 13b) for a mutual test intervention.
