ABSTRACT:
A data plotter includes a table for supporting a record sheet, a carriage movable thereon along one orthogonal axis, and a recording device carried by the carriage and movable with respect thereto along the other orthogonal axis. Relative movement is effected between the carriage and table by means of a drive including a pair of spaced racks mounted on one, each meshing with a motor-driven pinion mounted on the other. The data plotter further includes an electronic synchronizing system for synchronizing the operation of the two motors driving the two pinions along the two racks.
