Tachograph for motor vehicles
First Claim
1. Tachograph for motor vehicles with a microprocessor system comprising a time-and-date generator and which supplies a driver'"'"'s work-time data including driving time, ready time, and rest time, determines the "distance" and speed drive data with signals from the generator, characterized in that said tachograph is equipped with a printing device, in that a semiconductor memory on a data card directed to the driver serves as a data memory in that the work-time data and drive data are entered into defined memory areas of said data memory in addition to already imprinted data specific to said driver when the data card is introduced into said tachograph and in that readout of said data memory and a print out of a tubular drive record are triggered by feeding a print carrier in sheet form into a front feed slot on a front surface of said tachograph.

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.
