Abstract

The tachograph is for display and recording of vehicle running conditions. The tachograph of the main patent, a tachometer and a graph plotting attachment, has a means of controlling the recording needles in a known reference position on the translucent recording base. A window is provided in the display frame on the other side of the recording base. A device which is eccentric will respect to its rotation axis drives the recording needle and controls its position. This position control enables the recording to be as accurate as possible and ensures that errors and slack arising during manufacture are not taken into account in the measurement.
