摘要： A chart recorder is described in which the writing head (14) is rotatable by a motor (16) to position any one of several writing tips (20) over the paper. The motor (16) is mounted on the same carriage as the writing head (14) for movement relative to the paper.

摘要： In order to provide improved flexibility of operation consistent with small size. low mass and low inertia, a self-propelled drawing device 2 or 3 is driven by two independent wheels 12 whose axes are fixed, and has a writing tip 17 which marks the drawing medium 1 at a point which is not on the imaginary line joining the points of contact of the wheels with the drawing medium. In order to provide a simple umbilical cord which is less likely to impede the movement of the drawing device, the drawing device is connected to a stationary control device 5 by flexible conductors in the form of a ribbon 4 whose width lies in a vertical plane. Instead of a drawing device, the device can be arranged as a tracing device with counters on the wheels and a tracing tip instead of the writing tip.
