ABSTRACT:
The disclosed tachograph writes work data for motor vehicle work into a microprocessor-controlled EEPROM semiconductor memory mounted on a movable data card carried by the driver. A printing device prints out the content of a data card memory in the form of a tabular drive record in plain language. The face of the tachograph includes receiving slots located next to one another for the data cards of a driver and a co-driver, as well as a line display for guiding the driver as to how to key in information. A front slot in the face of the tachograph receives an unimprinted paper sheet. Two keys enter the work times, while the functions concerning the print-out of the driving record are controllable with a keyboard on the basis of information on the line display.
