Convertible platen for graphics plotter










Image Number 5 for United States Patent #4512505.

A convertible platen for use in a graphics plotter to allow its selective use as either a cut paper plotter or a roll paper plotter. The platen is formed from a specially designed aluminum extrusion and a pair is mounted with one on either side of the drum of a drum plotter between the drum and the supply/takeup rollers. The platens can be raised and held adjacent the drum and spanning the vacuum columns in the plotter to create a table having curved outer edges to support cut paper. They can be released and dropped into the vacuum columns whereby they lie against the outer surfaces and form the upper inner wall with curved upper edges over which paper smoothly is guided between the vacuum columns and the supply/takeup rollers.
