Appeal No. 1998-1441
Application No. 08/294,779
BACKGROUND
The invention is directed to an image forming device that includes an electro-optic
medium which is responsive to applied voltage and input beam intensity. Claim 55 is
reproduced below.
55. An image forming device, comprising:
means for providing a light valve including at least one layer of a
photoconductive material rendered conductive by light of at least a predetermined
intensity level and at least one layer of an electrooptic medium having at least a
predetermined electric field threshold, said light valve means having an image
forming region which is defined by at least portions of said layers of
photoconductive material and electrooptic medium which are in registration, said
image forming region of said light valve means being free of an electrically
conductive layer between said layers of photoconductive material and electrooptic
medium;
means for applying a modulated electric field across said layers of
photoconductive material and electrooptical medium of said image forming region
of said light valve means and modulating said electric field relative to said
predetermined electric field threshold of said electrooptic medium
means for producing at least one scanned light beam;
means for inputting an image to said photoconductive material by
modulating and scanning said at least one scanned light beam along the
photoconductive layer side of said image forming region of said light value [sic;
valve] means synchronous with the modulation of said electric field, said image
inputting means including a first deflector means for deflecting scanning of said at
least one scanned light beam in a first direction and second deflector means for
deflecting scanning of said at least one scanned light beam deflected by said first
deflector device [sic; means] in a direction essentially orthogonal to said first
direction;
a location of said photoconductive material becoming conductive to permit
application of said electric field to a corresponding location of said electrooptic
