Abstract
A calligraphic writing system includes a plotter of the type having a pen carriage, a pen holder mounted on the carriage, a recording table, and means for moving the pen carriage relative to the table so that a pen mounted on the pen holder draws images on a sheet of paper or other medium mounted on the table. The pen has an asymmetric point. The pen and pen holder include positioning means arranged such that the pen may be mounted in the pen holder only in a predetermined and fixed annular position relative to the pen holder and will be maintained in that position when the images are being drawn.
