Abstract

Casings for typewriters or the like office machines generally speaking exhibit covers in the upper part of the casing, which are arranged movably from a closed position into a position which releases a functional element such as printwheel, colour ribbon cassette etc. which is arranged on a carriage which is movable along the typed line. For this purpose the casing covers of known machines are removable and must be laid on the desk, for example when changing colour ribbons. This is very awkward for the operator and also requires a certain degree of skill. Moreover the removable cover does not enable ergonomically favourable arrangement of a line indicator device, since the operator cannot observe the typed line on the recording medium and the display on the line display device under optimum conditions. The invention avoids the above disadvantages in that the casing cover (11) is mounted displaceably into both end positions by means of a parallel guide in the upper part (3) of the casing and that in the opening position the casing cover (11) is located right above the keyboard (9). In an advantageous design of the subject matter of the invention the line display device is also arranged in the displaceable casing cover (11). Through the features of the invention, optimum working conditions are created for the operator using the simplest means. <IMAGE>

Description

Die Erfindung betrifft ein Gehäuse für eine Schreib- oder ähn­liche Büromaschine der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a housing for a typewriter or similar office machine of the type specified in the preamble of claim 1.

Es ist bei Schreibmaschinen und ähnlichen Maschinen weit ver­breitet bekannt, das Gehäuse nach oben durch einen abnehmbaren Deckel abzuschließen. Unterhalb dieses Deckels sind insbesondere das längs der Schreibwalze bewegbare Druckwerk mit den austausch­baren Funktionselementen wie Typenrad und Farbbandkassette ange­ordnet. Durch Abnahme des Gehäusedeckels wird der freie Zugriff zu diesem Druckwerk gestattet, ohne daß das gesamte Gehäuse vom Gerät abmontiert zu werden braucht. Es ist möglich, den Gehäuse­deckel derart auf dem Gerät anzuordnen, daß er von dem Gerät vollkommen abnehmbar ist und zur Seite gelegt werden kann oder aber daß der Deckel über Scharnierelemente am Gehäuse befestigt und nach oben aufklappbar ist. Im geschlossenen Zustand des Gehäusedeckels ist es vorteilhaft und in der aufgeklappten Stellung des Gehäusedeckels ist es erforderlich, diesen in den jeweiligen Lagen durch Verriegelungselemente zu arretieren.It is widely known in typewriters and similar machines to close off the housing by a removable cover. Below this cover, in particular, the printing unit, which can be moved along the platen, with the interchangeable functional elements such as the type wheel and ribbon cassette are arranged. By removing the housing cover, free access to this printing unit is permitted without the entire housing having to be removed from the device. It is possible to arrange the housing cover on the device in such a way that it can be completely removed from the device and set aside, or that the cover is attached to the housing via hinge elements and can be opened upwards. In the closed state of the housing cover it is advantageous and in the opened position of the housing cover it is necessary to lock it in the respective positions by means of locking elements.

Aufwendigere Schreibmaschinen und Textautomaten sind außerdem mit einer Zeilenanzeigeeinrichtung ausgestattet, die zumindest einige der jeweils zuletzt eingegebenen Schriftzeichen abbildet, bevor sie auf dem Aufzeichnungsträger ausgeschreiben werden. Der Be­diener kann anhand dieser Anzeigeeinrichtung seine Zeichneneingabe kontrollieren und erforderlichenfalls vor dem Ausschreiben korri­gieren.More complex typewriters and automatic text machines are also equipped with a line display device which reproduces at least some of the last entered characters before they are written out on the record carrier. Using this display device, the operator can check his drawing input and, if necessary, correct it before writing it out.

Bei bekannten Maschinen (DE-OS 27 42 992 zeigt ein typisches Beispiel einer solchen Maschine) ist die Anzeigeeinrichtung in der den Übergang zwischen hohem Gehäuseteil und niedrigem Ge­häuseteil bildenden Frontblende nahe der Tastatur angeordnet. Für einen geübten, blind schreiben Bediener, dessen Blick auf die Schreibwalze gerichtet ist, um Fortgang und Format seines Textes zu beobachten, hat diese Anordnung zur Folge, daß er den Blick zwischen der hoch liegenden Schreibzeile und der tief liegenden Anzeigeeinrichtung ständig hin- und herwandern lassen muß, um einerseits die Zeicheneingabe zu kontrollieren, solange sie noch korrigierbar ist, andererseits aber auch den Fortgang des Schrei­bens und damit die Einhaltung der Formatierung zu überwachen.In known machines (DE-OS 27 42 992 shows a typical example of such a machine) the display device is arranged in the front panel forming the transition between the high housing part and the low housing part near the keyboard. For An experienced, blind operator, whose gaze is directed at the platen roller to observe the progress and format of his text, has the result of this arrangement that he constantly moves his gaze back and forth between the high-lying writing line and the low-lying display device must, on the one hand, check the character input while it is still correctable, and on the other hand also to monitor the progress of the writing and thus the compliance with the formatting.

Durch die in der DE-OS 29 39 184 vorgeschlagene Lösung wird dieser Nachteil beseitigt. Hier ist eine sehr kleine Anzeigeein­richtung in unmittelbarer Nachbarschaft der Schreibzeile, also im Bereich des Typenträgers, angeordnet, so daß der Bediener die ausgeschreibene Zeile lesen und direkt im Anschluß daran die noch nicht ausgeschriebenen, auf der Anzeigeeinrichtung dargestellen Zeichen weiterverfolgen kann. Die Herstellung und Unterbringung einer solchen Anzeigeeinheit bringt aber wegen der erforderlichen Kleinheit wesentliche technische Probleme mit sich, und darüber­hinaus sind die bei einer solchen Anordnung nur sehr klein dar­stellbaren Zeichen, bedingt durch die im Vergleich mit den Druck­bild schlechte Wiedergabequalität der Anzeige, für den Bediener schwer zu lesen. Ein weiterer Nachteil besteht darin, daß immer nur sehr wenige der zuletzt eingegebenen Zeichen darstellbar sind, weil die Anzeigeeinrichtung wegen ihrer entlang der Zeile verschiebbaren Anordnung auch nur sehr kurz ausgestattet sein kann. Sie stellt somit nur eine Kontroll- und Korrekturhilfe für sofort nach der Eingabe bemerkete Tippfehler dar.This disadvantage is eliminated by the solution proposed in DE-OS 29 39 184. Here, a very small display device is arranged in the immediate vicinity of the writing line, that is to say in the area of the type carrier, so that the operator can read the line that has been written out and then immediately follow the characters that have not yet been written out and displayed on the display device. The manufacture and placement of such a display unit, however, entails significant technical problems because of the small size required, and moreover, the characters which can be represented very small in such an arrangement are difficult for the operator due to the poor reproduction quality of the display in comparison with the printed image to read. Another disadvantage is that only very few of the last entered characters can be represented because the display device can also be equipped only very briefly because of its arrangement which can be moved along the line. It is therefore only a control and correction aid for typing errors noticed immediately after entry.

Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse für eine Schreib- oder ähnliche Maschine mit einem aus einer Schließ­stellung in eine auf einem längs der Schreibzeile bewegbaren Schlitten angeordnete Funktionselemente wie Farbbandkassette, Typenrad etc. freigebende Stellung bewegbar gelagerten Gehäuse­deckel zu schaffen, durch den bessere Arbeitsbedingungen für die Bedienungsperson geschaffen werden. Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.The invention has for its object to provide a housing for a typewriter or similar machine with a housing cover movably mounted from a closed position into a functional element such as an ink ribbon cassette, typewriter, etc. arranged on a carriage that can be moved along the writing line, due to the better working conditions be created for the operator. This object is achieved by the invention characterized in claim 1.

Durch den Gehäusedeckel nach den erfindungsgemäßen Merkmalen wird erreicht, daß der Gehäusedeckel bei dem Schieben in die Öffnungs­stellung mit dem Gehäuse verbunden bleibt und dadurch eine leichte Bedienung ermöglicht. In vorteilhafter Ausgestaltung wird der Gehäusedeckel soweit über die Tastatur geschoben, daß deren Tasten nicht mehr betätigbar sind. Hierdurch werden Fehlbedienun­gen oder ungewollte Auslösungen von Funktionen über die Tasten sicher vermieden.The housing cover according to the features of the invention ensures that the housing cover remains connected to the housing when it is pushed into the open position and thereby enables easy operation. In an advantageous embodiment, the housing cover is pushed so far over the keyboard that its keys can no longer be actuated. This reliably prevents incorrect operation or unwanted triggering of functions via the buttons.

Durch die erfindungsgemäßen Merkmale nach Patentanspruch 3 wird eine umfangreiche und gut lesbare Zeilenanzeigeeinrichtung ge­schaffen, wobei der Bediener die Blickrichtung in einem nur geringen Umfang zu verändern braucht, um sowohl die Schreibzeile auf dem Aufzeichnungsträger als auch die Darstellung auf der Anzeigeeinrichtung zu beobachten. Es kann eine weitgehend na­türliche Körperhaltung eingenommen und beibehalten werden, wo­durch eine übermäßige Flexion der Nackenwirbel und eine Ver­krampfung der Rückenmuskulatur vermieden wird. Die Arbeit ist für den Bediener erheblich ermüdungsfreier, und Erkrankungen der Nackenwirbelsäule und der Rückenmuskulatur werden vorgebeugt.The inventive features according to claim 3 provide a comprehensive and easy-to-read line display device, the operator only having to change the viewing direction to a small extent in order to observe both the writing line on the recording medium and the display on the display device. A largely natural posture can be maintained and maintained, which prevents excessive flexion of the neck vertebrae and cramping of the back muscles. The work is considerably less tiring for the operator, and diseases of the neck spine and back muscles are prevented.

Da außerdem die Darstellung der zeichen auf der Anzeigeeinrich­tung groß und deutlich erfolgen kann, wird auch eine allzu schnelle Augenermüdung verhindert.In addition, since the characters can be displayed on the display device in a large and clear manner, eye fatigue is prevented too quickly.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen. Die Erfindung wird anhand eines Ausführungsbeispiels im folgenden näher be­schrieben. Es zeigen:

  • Figur 1 eine Schreibmaschine in schaubildlicher Dar­stellung,
  • Figur 2 ein Teil einer Schreibmaschine nach Figur 1 mit geöffnetem Gehäusedeckel und
  • Figuren 3 und 4 Einzelheiten aus Figur 1.
Further advantageous refinements of the subject matter of the invention can be found in the further subclaims. The invention is described in more detail below using an exemplary embodiment. Show it:
  • FIG. 1 shows a typewriter in a diagrammatic representation,
  • Figure 2 shows a part of a typewriter of Figure 1 with the housing cover open and
  • Figures 3 and 4 details from Figure 1.

Die Figur zeigt ein Gehäuse 1 einer Schreibmaschine mit einem in einem Gehäuseoberteil 3 zwischen einer Schreibwalze 5 und einer Tasten 7 aufweisen Tastatur 9 angeordneten Gehäusedeckel 11. Dieser Gehäusedeckel 11 ist auseiner Schließstellung in eine auf einem längs der Schreibwalze 5 bewegbaren Schlitten 13 ange­ordneten Funktionselemente wie Farbbandkassette 15, Typenrad 17 etc. freigebenden Öffnungsstellung bewegbar gelagert. Ein Papier­blatt 19 ist in bekannter Weise über die antreibbare Schreibwalze 5 transportierbar und über eine Papierführung 21 ableitbar. Der Gehäusedeckel 11 ist mittels einer Parallelführung in dem Ge­häuseoberteil 3 in die beiden Endstellungen verschiebbar gelagert und liegt in der Öffnungsstellung dicht über die Tasten 7 der Tastatur 9 derart, daß die Tasten 7 der Tastatur 9 durch die Bedienungsperson nicht mehr betätigbar sind.The figure shows a housing 1 of a typewriter with a housing cover 11 arranged in an upper housing part 3 between a typewriter 5 and a keys 7 and having a keyboard 9 15, type wheel 17, etc. releasably mounted opening position. A paper sheet 19 can be transported in a known manner via the drivable platen roller 5 and can be derived via a paper guide 21. The housing cover 11 is displaceably mounted in the upper end part 3 by means of a parallel guide and lies in the open position closely above the keys 7 of the keyboard 9 in such a way that the keys 7 of the keyboard 9 can no longer be actuated by the operator.

Weiterhin weist der Gehäusedeckel 11 eine rechteckförmige Aus­sparung 23 auf, in der eine mindestens eine vollständige Zeile anzeigende Zeilenanzeigevorrichtung 25 verschwenk- und verrastbar gelagert ist. Die als Display bekannte Zeilenanzeigevorrichtung 25 ist über ein Leitkabel 27 mit einer auf der Bodenplatte 29 des Gehäuses 1 fest angeordneten Steuervorrichtung elektrisch ver­bunden.Furthermore, the housing cover 11 has a rectangular recess 23, in which a line display device 25, which displays at least one complete line, is mounted so that it can be pivoted and locked. The line display device 25 known as the display is electrically connected via a guide cable 27 to a control device fixedly arranged on the base plate 29 of the housing 1.

Die Zeilenanzeigevorrichtung 25 besteht aus einem mehrere Zeilen darstellenden Display, das in einem Rahmen 31 eingebettet ange­ordnet ist. Dieser Rahmen 31 weist mittig an den Seiten 33, 35 Lagerzapfen 37, 39 auf, die in Lagerbohrungen 41, 43 des Gehäuse­oberteiles 3 schwenkbar gelagert sind. Um den Rahmen 31 mit dem Display 25 stufenlos in jeder Einstellage arretieren zu können, ist der Rahmen 31 an einer Unterseite 45 einer Längsseite 47 mit einem vorstehenden Bremsarm 49 versehen, welcher durch zwei gegeneinander federnde Bremsnocken 51, 53 eines Bremsgliedes (55) aus Kunststoff beaufschlagt wird. Die Bremsnocken 51, 53 sind mit den freien Enden von an dem gabelförmig ausgebildeten Bremsglied 55 angeordneten Haltearmen 57, 59 einstückig ausgebildet. Das Bremsglied 55 ist mittels eines Rastzapfens 61 in einer Bohrung 63 des Gehäusedeckels 11 verrastbar angeordnet, Um eine lange Lebensdauer der Federwirkung der Haltearme 57, 59 zu gewähr­leisten, werden die Haltearme 57, 59 mit den Bremsnocken 51, 53 durch einen Sprengring 65 gengeneinander gepreßt.The line display device 25 consists of a display representing several lines, which is arranged embedded in a frame 31. This frame 31 has in the middle on the sides 33, 35 bearing journals 37, 39 which are pivotably mounted in bearing bores 41, 43 of the upper housing part 3. In order to be able to lock the frame 31 with the display 25 steplessly in each setting position, the frame 31 is provided on an underside 45 of a longitudinal side 47 with a protruding brake arm 49, which is formed by two brake cams 51, 53 resilient against one another of a brake member (55) made of plastic is applied. The brake cams 51, 53 are with the free ends of on the fork-shaped brake member 55 arranged holding arms 57, 59 formed in one piece. The brake member 55 is arranged by means of a locking pin 61 in a bore 63 of the housing cover 11 so as to ensure a long service life of the spring action of the holding arms 57, 59, the holding arms 57, 59 with the brake cams 51, 53 are pressed against one another by a snap ring 65 .

Die Parallelführung zum Verschieben des Gehäusedeckels 11 weist zwei Schwenkhebel 67, 69 auf, von denen je ein Schwenkhebel 67, 69 an den beiden Seiten im Maschinengestell gelagert ist. Die Schwenkhebel 67, 69 sind je über einen Verbindungsarm 71, 73 mit dem Gehäusedeckel 11 in Nähe der vorderen Längskante 75 gelenkig verbunden. Andererseits weist die Parallelführung im Bereich der hinteren Längsseite 77 des Gehäusedeckels 11 an dessen Unterseite 79 Führungen 81, 83 auf, welche auf Führungskanten 85, 87 des Gehäuseoberteiles 3 gleitbar gelagert sind. Diese Führungskanten 85, 87 sind die Seitenkanten in der Öffnung 89 für den Gehäuse­deckel 11 in dem Gehäuseoberteil 3.The parallel guide for moving the housing cover 11 has two pivot levers 67, 69, of which one pivot lever 67, 69 is mounted on the two sides in the machine frame. The pivot levers 67, 69 are each articulated via a connecting arm 71, 73 to the housing cover 11 in the vicinity of the front longitudinal edge 75. On the other hand, the parallel guide in the area of the rear longitudinal side 77 of the housing cover 11 has on the underside 79 guides 81, 83 which are slidably mounted on guide edges 85, 87 of the upper housing part 3. These guide edges 85, 87 are the side edges in the opening 89 for the housing cover 11 in the upper housing part 3.

Die Schwenkhebel 67, 69 weisen je einen Einhägearm 91, 93 für als Verriegelungsglieder dienende Federn 95, 97 auf, welche mit ihren anderen Enden derart in Einhängungen 99, 101 der Bodenwanne 29 derart eingehängt sind, daß die Federn 95, 97 beim Verschieben des Gehäusedeckels 11 in die beiden Endstellung über eine Tot­punktlage verschwenkt werden. Hierdurch wird eine sichere Ver­riegelung des Gehäusedeckels in den beiden Endlagen gewähr­leistet, ohne daß dazu besondere Rastelemente erforderlich sind.The pivot levers 67, 69 each have a Einhägearm 91, 93 for serving as locking members springs 95, 97, which are hooked with their other ends in such hangings 99, 101 of the floor pan 29 such that the springs 95, 97 when moving the housing cover 11 can be pivoted into the two end positions via a dead center position. This ensures a secure locking of the housing cover in the two end positions without the need for special locking elements.

Um ein Verkanten des Gehäusedeckels 11 beim Verschieben in eine der Endlagen zu verhindern, sind die beiden Schwenkhebel 67, 69 mit einer gemeinsamen Drehachse 103 fest verbunden, welche in der Boden wanne 29 drehbar gelagert ist. Außerdem weist ein Schwenk­hebel 69 einen Amschlagarm 105 für einen Schalter 107 in der Bodenwanne 29 auf, über den (107) die Stromzufuhr zu den Bauele­menten in der Maschine unterbrechbar ist. Hierdurch wird gewähr­leistet, daß bei geöffnetem Gehäusedeckel 11 keine Funktionen auslösbar sind.In order to prevent tilting of the housing cover 11 when moving into one of the end positions, the two pivot levers 67, 69 are fixedly connected to a common axis of rotation 103, which is rotatably mounted in the bottom pan 29. In addition, a pivot lever 69 has a stop arm 105 for a switch 107 in the floor pan 29, via which (107) the power supply to the components in the machine can be interrupted. This ensures that no functions can be triggered when the housing cover 11 is open.
