Abstract

Es wird eine Tastaturmatte (3) mit Hintergrundbeleuchtung vorgeschlagen, durch die bei gleichzeitiger Gewährung einer mehrfarbigen Tastenhinterleuchtung die Handhabbarkeit bei der Fertigung und dadurch die Fertigung selbst vereinfacht wird. Eine solche Tastaturmatte (3) ist einstückig ausgebildet, so dass ein Aufwand nur für eine Tastaturmatte (3) pro einem betreffenden Apparat vorzuhalten ist bei gleichzeitiger Gewährung einer mehrfarbigen Tastenhinterleuchtung. Erreicht wird das durch Einbringen von Langlöchern (8) in der Tastaturmatte (3) zwischen den Bereichen (6; 7) der Tastaturmatte (3), die verschiedenfarbig hinterleuchtet werden sollen, ohne dabei die Tastaturmatte (3) zu zerteilen. Mit dieser Maßnahme ist zwischen den betreffenden Bereichen (6; 7) der Tastaturmatte (3) eine Lichtunterbrechung gegeben. Kleine punktuelle Verbindungsstege (9) mit kleinen Querschnitten, die die Langlöcher (8) hinterlassen, ermöglichen keinen großen Lichtfluss innerhalb der Tastaturmatte (3), so dass eine Lichtmischung zwischen betreffenden Bereichen (6; 7) der Tastaturmatte (3) in der Praxis vermieden ist. Die Verbindungsstege (9) halten aber andererseits die betreffenden Bereiche (6; 7) zu einer einzigen Tastaturmatte (3) zusammen.

Figure 00000001
It is proposed a keypad (3) with backlight, by the simultaneous granting of a multi-colored key backlighting the handling in production and thereby the production itself is simplified. Such a keypad mat (3) is integrally formed, so that an expense only for a keypad mat (3) pro a relevant apparatus is to be maintained while granting a multi-colored Tastenhinterleuchtung. This is achieved by inserting oblong holes (8) in the keypad mat (3) between the areas (6; 7) of the keypad mat (3), which are to be backlit in different colors, without dividing the keypad mat (3). With this measure, a light interruption is given between the respective areas (6; 7) of the keypad mat (3). Small punctiform connecting webs (9) with small cross-sections which leave the oblong holes (8) do not allow a large flow of light within the keymat (3), so that a light mixture between relevant areas (6; 7) of the keymat (3) avoided in practice is. On the other hand, the connecting webs (9) hold the respective areas (6, 7) together to form a single keypad mat (3).
