Abstract
Disclosed herein is a coordinate plotter with at least one automatic punching device, adapted to draw a desired picture by shifting a table and an autographic head, which is directed downwardly from a point right above the table, in the X-axis and Y-axis directions respectively. The at least one automatic punching device is provided in adjacent to a side edge parallel to the moving direction of the table and at a height equal to the upper surface of the table so as to form a positioning hole through a sheet laid on the table for drawing the desired picture thereon. The specification also discloses a method and apparatus for conveying sheets to the coordinate plotter.
