Abstract
A recording device using a circular chart wherein the major portion of the chart containing the central portion thereof is driven so as to rotate in a first plane, the lesser portion thereof being folded so as to rotate in a second plane angularly disposed, and preferably orthogonal, to the drive plane. A writing means, such as a stylus, is in writing contact with the chart on its major portion so that the recordal of information thereon occurs in the drive plane. The folded lesser portion of the chart is retained in place during rotation by the inner surface of one side of the case in which it is enclosed.
Claims6
