Abstract

Bei einem Taxameter (1) ist es üblich die für die Anzeige verwendete Flüssigkristallanzeige (4) rückseitig mittels eines Lichtleiters (19) zu beleuchten. Für die Beleuchtung der Steuertasten (7) des Taxameters (1) wird vorgeschlagen die Tastenschäfte (28) aus lichtleitendem Werkstoff herzustellen und sie in an dem Lichtleiter (19) angeformten Führungskanälen zu haltern.

In the case of a taximeter (1), it is customary to illuminate the back of the liquid crystal display (4) used for the display by means of a light guide (19). For illuminating the control buttons (7) of the taximeter (1), it is proposed to manufacture the button shafts (28) from light-conducting material and to hold them in guide channels formed on the light guide (19).
