ABSTRACT OF THE DISCLOSURE The invention relates to a multi-color pen recording device suitable for a data recording instrument in which a rotary drum supporting a plurality of different colored pens around its periphery is mounted on a carriage which can be driven laterally across the recording paper, which can itself be driven longitudinally, so that the longitudinal axes of the rotary drum and the pens are perpendicular to the paper. The rotary drum is rotated under the guidance of a control system until the selected pen is in the writing position, and then a pen pressing means presses that pen towards the recording paper so as to touch it, so that as the recording paper is driven longitudi- nally and the carriage is driven laterally, the data can be drawn by the selected pen on the paper.
