Abstract
A measuring device with an integrated light beam scanning means for detecting the number of revolutions of a rotating body, contrast-coded data (bar codes) being capable of detection by means of the light beam scanning means. The measuring device includes a selecting means to select the mode of operation consisting of measuring the number of revolutions or detecting data. An analyzing means analyzes signals outputted by the scanning means (1) and automatically selects one of the modes of operation consisting of measuring the number of revolutions and detecting data in dependence on the result of the analysis.
