motor vehicle tachograph, tachograph paper strip and method of aligning a longitudinally displaceable paper strip with respect to a tachograph printing device

摘要

tachograph for a motor vehicle, paper strip for a tachograph and method of aligning a paper strip longitudinally displaceable with respect to a printing device on a tachograph. the present invention relates to a paper strip 6 for a tachograph 1 having a series of marks 17, 18 extending transversely with respect to its direction of movement in the tachograph 1. the marks (17, 18) have different lengths and are perceived by a sensor (10, 11). the sensor 10, 11 generates a signal sequence which provides definitive information about a deviation of paper strip 6 in the printing unit 7. a control device (12) drives a printing unit (7) of the tachograph (1) and balances the offset.
