The invention relates to a keyboard for data-input apparatuses having a large number of input keys. In order to use such keyboards universally, the key caps (1) of some of the keys are provided with selectable LCD display elements (3). <IMAGE>

Description

Tastatur für DateneingabegeräteKeyboard for data entry devices

Die Erfindung betrifft eine Tastatur für Dateneingabegeräte mit einer Vielzahl von Eingabetasten.The invention relates to a keyboard for data input devices with a Variety of input keys.

Bei derartigen Tastaturen besteht ein großes Problem darin, daß je nach Anwendungsgebiet ein und derselben Taste unterschiedliche Symbole zugeordnet werden müssen.A major problem with such keyboards is that ever Depending on the area of application, one and the same key is assigned different symbols Need to become.

Es sei in diesem Zusammenhang nur die Vielzahl der Tastenbelegungen erwähnt, die sich durch die vielen unterschiedllchen nationalen Tastaturen ergeben.In this context it is only the multitude of key assignments mentioned, which result from the many different national keyboards.

Bisher wurden daher entweder verschisdene Tastaturen benötigt, oder man wechselte einige der Tastenkappen aus.So far, therefore, either different keyboards were required, or some of the keycaps were changed.

Eine andere Möglichkeit bestand in der Benutzung von unterschiedlichen Auflegefolien. Diese Änderungsmöglichkeiten waren entweder teuer und aufwendig, oder sie wiesen Nachteile beim Gebrauch auf.Another possibility was to use different ones Lay-on foils. These change options were either expensive and time-consuming, or they have had disadvantages in use.

Aufgabe der vorliegenden Erfindung ist es eine Tastatur für Dateneingabegeräte mit einer Vielzahl von Eingabetasten anzugeben, bei der die Tastensymbole einfach geändert werden können.The object of the present invention is a keyboard for data input devices with a variety of input keys to specify where the key symbols are simple can be changed.

Diese Aufgabe wird für eine Tastatur der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Tastenkappen eines vorgegebenen Teils der Eingabetasten LCD-Anzeigeelemente enthalten.This object is achieved according to the invention for a keyboard of the type mentioned at the outset solved in that the key caps of a predetermined part of the input keys LCD display elements included.

Auf diese Weise können die Symbole durch geänderte Ansteuerung der LCD-Anzeigeelemente leicht geändert werden, ohne einen Eingriff in die Tastatur selbst vorzunehmen. Damit ist ein und dieselbe Tastatur universell anwendbar.In this way, the symbols can be changed by controlling the LCD display elements can be changed easily without any intervention in the keyboard itself. This means that one and the same keyboard is universal applicable.

Eine Weiterbildung der erfindungsgemäßen Tastatur ist dadurch gekennzeichnet, daß beim Umschalten des Datensystems auf eine andere Tastaturvariante automatisch die durch die LCD-Anzeigeelemente angezeigten Tastensymbole geändert werden.A further development of the keyboard according to the invention is characterized in that that automatically when switching the data system to another keyboard variant the button icons displayed by the LCD indicators are changed.

Im folgenden soll die erfindungsgemäße Tastatur anhand einer Zeichnung näher beschrieben werden. Es zeigen Fig. 1 einen Schnitt durch eine Taste der erfindungsgemäßen Tastatur mit einem LCD-Anzeigeelement, und Fig. 2 eine Draufsicht auf eine Taste gemäß Fig. 1.In the following, the keyboard according to the invention will be based on a drawing are described in more detail. 1 shows a section through a key of the invention Keyboard with an LCD display element, and FIG. 2 shows a plan view of a key according to FIG. 1.

Die Taste der erfindungsgemäßen Tastatur besteht im wesentlichen aus der Tastenkappe 1 und dem Tastenkörper 2. Unterhalb der Oberfläche der Tastenkappe 1 ist gemäß der Erfindung ein LCD-Anzeigeelement 3 vorgesehen.The key of the keyboard according to the invention consists essentially of the keycap 1 and the key body 2. Below the surface of the keycap 1, an LCD display element 3 is provided according to the invention.

Dieses LCD-Anzeigeelement 3 ist über ein Mini-Flachbandkabel 4 mit einem Flachbandstecker 5 verbunden, der sich im unteren Teil des Tastenkörpers 2 befindet und Anschlußstifte 6 aufweist, auf die Steuerleitungen aufsteckbar sind. Diese Steuerleitungen führen zu einer hier nicht dargestellten Steuerung, mit deren Hilfe je nach Einsatzgebiet der Tastatur auf einfache Weise die angezeigten Symbole geändert werden können. In Fig. 2 ist schematisch eine derartige LCD-Anzeige 7 in einer Tastenkappe 1 dargestellt. Auf diese Weise ist ein und dieselbe Tastatur universell einsetzbar.This LCD display element 3 is via a mini ribbon cable 4 with connected to a ribbon connector 5, which is located in the lower part of the key body 2 is located and has connecting pins 6, onto which control lines can be plugged. These control lines lead to a control, not shown here, with their Help depending on the area in which the keyboard is used in a simple manner using the symbols displayed can be changed. Such an LCD display 7 is schematically shown in FIG a key cap 1 shown. In this way, the same keyboard is universal applicable.

Die LCD-Anzeigeelemente 3 in der Tastenkappe 1 können durch Glas- oder Plexiglasplättchen, die möglichst reflektionsarm ausgeführt sind, geschützt werden. Auch besteht die Möglichkeit, den Kontrast der LCD-Anzeigeelemente durch Unterlegung von floureszierenden oder glitzernden Flächen zu verbessern. The LCD display elements 3 in the key cap 1 can be protected by glass or Plexiglas plates that are designed to be as low-reflective as possible. It is also possible to improve the contrast of the LCD display elements by placing fluorescent or glittering surfaces underneath.
