Description

Die Erfindung betrifft eine Bedieneinrichtung für ein Kommunikationsgerät, insbesondere eine Fernbedienung für ein Gerät der Unterhaltungselektronik gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an operating device for a communication device, in particular a remote control for a consumer electronics device according to the preamble of claim 1.

Fernbedienungen sind als sogenannte Fernbedienungsgeber zur Bedienung von Geräten der Unterhaltungselektronik, beispielsweise Fernsehgeräten, Videorecordern sowie Audiogeräten, gebräuchlich. Da derartige Fernbedienungen häufig auch in abgedunkelten Räumen vom Benutzer bedient werden sollen, sind auch Fernbedienungsgeber bekannt, deren Tastaturfelder beleuchtbar sind.Remote controls are used as so-called remote control transmitters of consumer electronics devices, for example television sets, VCRs and audio equipment, in use. Because such Remote controls are often used in darkened rooms by the user to be operated, remote control transmitters are also known, whose Keypads are illuminated.

Aus DE 90 13 860 U1 ist eine Fernbedienung für elektronische Geräte bekannt, deren Bedienelemente beleuchtet sind. Die Beleuchtung erfolgt mit Hilfe von flexiblen Lichtleitern. Zur Beleuchtung ist eine einzige aus einer Batterie gespeiste Lichtquelle vorgesehen.DE 90 13 860 U1 is a remote control for electronic devices known, the controls are illuminated. The lighting is done with With the help of flexible light guides. For lighting is a single one Battery powered light source provided.

Der Erfindung liegt die Aufgabe zugrunde, eine Bedieneinrichtung der eingangs genannten Art anzugeben, dessen Tastaturfeld ohne großen Aufwand möglichst homogen beleuchtbar ist und die einfach herstellbar ist.The invention has for its object an operating device Specify the type mentioned, the keyboard without large Effort can be illuminated as homogeneously as possible and is easy to manufacture.

Diese Aufgabe wird durch eine Bedieneinrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved by an operating device with the in claim 1 specified features solved.

Durch die Lichtleitmittel erfolgt eine homogene Verteilung des zur Verfügung stehenden Lichts, insbesondere an die Randbereiche der zu beleuchtenden Tasten, wodurch sich eine einfachere und ergonomischere Handhabbarkeit der Bedieneineinrichtung auch bei abgedunkelten Sichtverhältnissen ergibt. Als besonders geeignetes Material für die Leuchtmittel hat sich erwiesen, daß die Leuchtmittel aus einem lichtdurchlässigen Material gebildet sind, wobei die Lichtleitmittel an die Form der zu beleuchtenden Tasten angepaßt sind. Eine besonders einfache Herstellung der Lichtleitmittel ergibt sich dadurch, daß die Lichtleitmittel einstückig und zusammenhängend ausgebildet sind.The light guide means that there is a homogeneous distribution of the available standing light, especially at the edge of the area to be illuminated Buttons, making it easier and more ergonomic to use of the control device even in darkened visibility. A particularly suitable material for the illuminants has been found to be that the illuminants are formed from a translucent material, wherein the light guide means are adapted to the shape of the keys to be illuminated. A particularly simple manufacture of the light guide means results from that the light guide means are integrally and coherently formed.

Eine energie- sowie platzsparende Realisierung der Leuchtmittel ergibt sich dadurch, daß die Mittel zur Beleuchtung der Tasten aus Leuchtdioden gebildet werden, die im Bereich des Tastaturfelds angeordnet sind.This results in an energy-saving and space-saving realization of the lamps in that the means for illuminating the keys from light emitting diodes are formed, which are arranged in the area of the keyboard.

Die Lichtleitmittel können aus einem Material gebildet werden, das zur Erzeugung bestimmter Lichteffekte auch farblich ausgebildet sein kann.The light guide means can be formed from a material which is used for Generation of certain lighting effects can also be colored.

Der Lichtleiteffekt kann dadurch verstärkt werden, daß die Lichtleitmittel im unteren Bereich abgewinkelt sind.The light guide effect can be enhanced by the fact that the light guide means in lower area are angled.

Eine Alternative hierzu besteht darin, daß die Lichtleitmittel im unteren Bereich eine Einkerbung aufweisen.An alternative to this is that the light guide means in the lower Area have a notch.

Der optische Eindruck auf den Betrachter kann dadurch weiter verbessert werden, daß die Lichtleitmittel im oberen Bereich eine Einkerbung aufweisen.This can further improve the visual impression on the viewer be that the light guide means have a notch in the upper region.

Im folgenden wird die Erfindung anhand der in den Fig. dargestellten Ausführungsbeispielen näher beschrieben und erläutert.In the following the invention with reference to that shown in the figures Exemplary embodiments described and explained in more detail.
