Abstract

Abstract A SYSTEM FOR RAPIDLY IMAGING CHARACTERS HAVING DIFFERENT RELATIVE WIDTHS OF A RADIATION-SENSITIVE SURFACE USING THE CONCEPT OF OPTICAL LEVERAGE IS DISCLOSED. CHARACTER IMAGES ARE PROJECTED FROM ONE OR MORE PROJECTION ZONES ON A CHARACTER MATRIX TO A RECEIVING SURFACE SUCH AS A FILM. PRIOR TO BEING FOCUSED ON THE FILM, EACH OF THE PROJECTED CHARACTER IMAGES ARE VARIABLY SPACED FROM ONE ANOTHER IN ACCORDANCE WITH THEIR RESPECTIVE RELATIVE WIDTHS IN ORDER TO FORM LINES OF COMPOSITION HAVING PROPORTIONATELY SPACED CHARACTERS. THE FOCUSING SYSTEM NORMALLY INCLUDES A SIZE-CHANGING MECHANISM. CHARACTER SPACING MAY BE ACCOMPLISHED BY ANY OF SEVERAL EMBODIMENTS WHICH EMPLOY THE POTICAL LEVERAGE CONCEPT. ONE EMBODIMENT COMPRISES AT LEAST ONE MOVABLE RIGHT-ANGLE PRISM WHICH IS ASSOCIATED WITH A FIXED, ROTATING CHARACTER MATRIX-THE PRISM SPACES PROJECTED IMAGES OF SELECTED CHARACTERS ON THE FILM BY STRAIGHT-LINE MOVEMENT IN A PLANE PARALLEL TO THE FILM PLANE.
