Abstract: A taximeter is disclosed which comprises a housing having a front side, an electronic computer, data memories, a buffer battery, a display arrangement, one of pushbuttons and keys for providing functional control and for calling up contents of at least one of the data memories which is assigned to the display arrangement, and a parametric and diagnostic contacting arrangement. The parametric and diagnostic contacting arrangement is accessible from the front side of the housing. The parametric and diagnostic contacting arrangement and the buffer battery are accessible through an aperture which is coverable by one of a lead-sealed lid and a cover and is provided at the front side of the housing.

Abstract: An assembly-optimized arrangement of the functional elements of a taximeter is disclosed which comprises a two-part housing which further comprises a front housing component and a rear housing component. The arrangement further comprises a printed circuit board carrying the electronic computer and the data and memory of the taximeter, a liquid crystal display, one of an optical fiber and an optical light guide allocated to the rear side of said liquid crystal display, a glass pane, control keys, a receiving means and an aligning means. The receiving means and the aligning means are designed at the front housing component which enable, during assembly of the taximeter, a loose retention of at least one of the glass pane, the liquid crystal display and the optical fiber at the front of the housing component by one of insertion and mounting. An attachment of functional elements occurs indirectly by fastening the printed circuit board to the front housing component.

Abstract: A control arrangement for a display unit, for use in a motor vehicle for digital presentation of vehicle operational data, is located within a housing having a display face. A multi-way push button is accessible on the display face and extends into the housing for operating at least two switches. The push button is pivotally mounted for operating different ones of the switches when specific operational data is desired.
