ABSTRACT:
A drum plotter having an optical light head which projects a beam of light onto a light sensitive film as the head and film are moved relative to one another includes an aperture plate that is shifted relative to the beam in order to adjust the image produced by the beam on the film. The aperture plate is selectively shifted within the plotting head relative to the beam by means of an abutment pin that is engaged with the aperture plate at a travel limit of the plotting head. Movement of the plotting head toward the abutment after engagement of the pin and plate moves the late within the head and shifts one of a plurality of apertures into registration with the beam axis to change or control the image produced by the beam on the light sensitive film.
