Die hinterleuchtende Lichtquelle emittiert ihr Licht in Richtung auf ein lichtdurchlässiges Fenster in der Folie.From the DE 299 21 276 U a keyboard with backlit keys is known, wherein the characters and / or symbols of the keys are applied to a foil. The backlit light source emits its light towards a translucent window in the film.

Abhängig von der Umgebung besteht ein Bedarf, ein darzustellendes Zeichen oder Symbol einer Taste, die rückwärtig beleuchtet wird, in bestimmten Farben darzustellen. Hierzu wäre es denkbar, bei der eingangs genannten Tastatur eine Folie aus farbigem Material zu verwenden und in die Tastenkappe einzulegen, so dass diese von der hinterleuchtenden Lichtquelle beschienen wird. Hierzu muss die Tastenkappe transluzent sein, also beispielsweise aus einem transluzenten Kunststoff bestehen. Die Montage einer derartigen Tastatur erscheint zu aufwendig.Depending on there is a need for the environment, a character to be displayed or Symbol of a button backlit is going to show in certain colors. For this it would be conceivable in the aforementioned keyboard, a film of colored material to use and insert in the key cap, so that this the backlit light source is illuminated. For this the must Button cap translucent, so for example from a translucent Plastic exist. The installation of such a keyboard appears too expensive.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung eine Tastenkappe der eingangs genannten Art anzugeben, bei der ein darzustellendes Zeichen und/oder Symbol einer zugehörigen Taste in einer bestimmten Farbe angezeigt werden soll, wobei keinerlei komplizierte Montageschritte erforderlich sein sollen. Darüber hinaus soll eine Tastatur angegeben werden, in der die erfindungsgemäße Tastenkappe Anwendung findet.In front In this background, it is the object of the present invention specify a key cap of the type mentioned, in the one to be displayed character and / or symbol of an associated button to be displayed in a specific color, with no complicated assembly steps should be required. Furthermore should be given a keyboard in which the key cap according to the invention Application finds.

Gelöst wird diese Aufgabe durch eine Tastenkappe mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Is solved This object is achieved by a keycap with the features of the claim 1. Advantageous developments emerge from the dependent claims.

Die erfindungsgemäße Tastenkappe besteht demnach aus einem transluzenten Kunststoff, der mit Farbpigmenten vorbestimmter Farbe gleichmäßig durchsetzt ist und nach außen hin mit einem weitgehend lichtundurchlässigen Farblack beschichtet ist, aus dem heraus das Zeichen und/oder das Symbol herausgearbeitet ist. Die Tastenkappe ist dazu vorgesehen, rückseitig von einer Lichtquelle, beispielsweise einer weißen LED angestrahlt zu werden. Der farbige Kunststoff sorgt dafür, dass nur Licht der gewünschten Farbe aus der Tastenkappe nach außen austreten kann, und zwar nur an den Stellen, an denen der Farblack in der Zeichenform bzw. Symbolform herausgearbeitet, d.h. entfernt worden ist.The Button cap according to the invention therefore consists of a translucent plastic, which is colored with pigments predetermined color evenly interspersed is and outward coated with a largely opaque color coat is out of which the sign and / or the symbol worked out is. The keycap is provided to the rear of a light source, for example, a white one LED to be illuminated. The colored plastic ensures that only light of the desired Color from the key cap can escape to the outside, namely only in the places where the color lacquer in the character form or Symbol form worked out, i. has been removed.

Gemäß einer besonders vorteilhaften Ausführungsform ist das Zeichen oder Symbol aus dem Farblack herausgelasert. Dies erlaubt eine rasche und saubere Erzeugung des herauszuarbeitenden Zeichens oder Symbols.According to one particularly advantageous embodiment is the character or symbol herausgelasert from the color coat. This allows a quick and clean generation of the character to be worked out or symbol.

Hinsichtlich der Tastatur ist zu bemerken, dass diese eine Leiterplatte aufweist, die mit elektronischen Tasten sowie mit wenigstens einer Lichtquelle pro Taste bestückt ist, wobei die Taste jeweils eine vorerwähnte Tastenkappe trägt, derart, dass die wenigstens eine Lichtquelle ihr Licht in Richtung auf das Zeichen oder Symbol der Tastenkappe emittiert. Es können in einer Tastatur durchaus Tastenkappen mit unterschiedlicher Färbung zum Einsatz kommen, wobei beispielsweise auf der Tastatur mehrere Funktionsblöcke jeweils unterschiedlicher Farben gebildet sein können.Regarding the keyboard is to be noted that this has a printed circuit board, the with electronic buttons and with at least one light source equipped per key is, wherein the key carries a aforementioned key cap, in each case, that the at least one light source shines its light towards the sign or symbol of the key cap emitted. It may well be in a keyboard Keycaps with different coloring are used, wherein For example, on the keyboard several function blocks each different colors can be formed.

Gemäß einer noch anderen Weiterbildung können die erfindungsgemäßen Tastenkappen der Tasten einer Tastatur mit farblich unterschiedlichen Farblacken beschichtet sein. Auch hier lassen sich beispielsweise Gruppen von Tasten in der Tastatur anordnen, die beispielsweise verschiedene Funktionsgruppen eines Aggregates in vorgegebener Weise ansteuern.According to one still other training can the key caps invention the keys of a keyboard with differently colored colors be coated. Here too, for example, groups of Arranging keys in the keyboard that are different, for example Control function groups of an aggregate in a predefined manner.

Die Erfindung wird beispielhaft anhand der einzigen Zeichnungsfigur näher erläutert.
