Method and device for measuring and/or controlling preferably slow movements, e.g. for controlling the feedrate of recording paper

摘要

The invention relates to a method which is advantageously employed, for example, in data recorders for controlling the recording strip. In this case, the object whose movement is to be measured or controlled - the recording paper in the example - carries the information necessary for the method, which can consist, for example, of uncoded, overprinted marks.
