US Patent:
43842984, May 17, 1983
Filed:
Mar 16, 1982
Appl. No.:
6/358551
Inventors:
Lawrence J. LaBarre - Mountain View CA
Bernard M. Oliver - Los Altos Hills CA
Charles E. Tyler - Sunnyvale CA
Dennis C. Thompson - Campbell CA
Armand P. Neukermans - Palo Alto CA
Douglass McManigill - Palo Alto CA
Assignee:
Hewlett Packard Company - Palo Alto CA
International Classification:
G01D 1516
G01D 1524
US Classification:
346129
Abstract:
An X-Y recorder for high speed plotting on a plain web, i. e. , a web without registration holes or other special means to maintain alignment of the web during plotting. Two embodiments of these plotters are disclosed with one degree of motion being achieved by moving the web and the second degree of motion being obtained by moving a pen assembly substantially perpendicularly to the movement of the web. To enhance the repeatability of the plotting on the web as it is moved back and forth, a random rough surfaced drive wheel assembly is included with that wheel surface making indentations along one surface of the driven edge of the web as it is first passed through the drive wheel assembly. Then as the web is reversed, these indentations substantially remesh with the random rough surface of the drive wheels.
