ABSTRACT:
The invention relates to high speed means of selecting graphic symbols from an illuminated array of such symbols, whereby a series of individual images thereof will be established along a common optical axis of a recording apparatus and thereupon directed toward a predetermined line position across the surface of a light responsive display medium. More particularly, the invention includes the use of light from a laser source of radiant energy for illuminating the array of symbols and acousto-optic laserbeam deflector means utilized in a manner whereby images of the illuminated symbols are selected for viewing along the optical axis in response to voltages connected to the deflector means. Following each symbol selection a predetermined area of the display medium will be exposed to the image of the symbol under the control of secondary laserbeam reflector means.
