Claim 1

THE METHOD OF FABRICATING A CONTROL UNIT FOR ELECTROSTATIC IMAGE RECORDING APPARATUS, SUCH METHOD COMPRISING; PROVIDING A LONGITUDINAL LAMINATED BASIC SUPPORT WHICH INCLUDES A FIRST FIBER OPTIC BUNDLE MEMBER SANDWICHED BETWEEN A SECOND AND A THIRD SUPPORT MEMBER, AT LEAST SUCH SECOND SUPPORT MEMBER BEING DIELECTRIC AND TRANSPARENT AND AT LEAST ONE LONGITUDINAL SURFACE OF EACH OF SUCH THREE MEMBERS EXTENDING IN THE SAME PLANE TO FORM A COMMON PLANAR SURFACE HAVING THE INDIVIDUAL FIBER OPTICS OF SAID FIRST MEMBER DISPOSED NORMAL TO SUCH SURFACE; PROVIDING A PATTERN OF A THIN ELECTRICALLY CONDUCTIVE COATING MATERIAL ADJACENT SAID PLANAR SURFACE, SUCH PATTERN COMPRISING FIRST AND SECOND COATED AREAS EXTENDING SUBSTANTIALLY THE FULL LENGTH OF SAID LONGITUDINAL SURFACES OF SAID SECOND AND THIRD SUPPORT MEMBERS RESPECTIVELY TO FORM FIRST AND SECOND BUS BARS RESPECTIVELY, AND SUCH PATTERN ALSO INCLUDING A ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING ADJACENT SAID PLANAR SURFACE BETWEEN SAID BUS BARS AND ISOLATED THEREFROM AND FROM EACH OTHER TO FORM INDIVIDUAL DISCRETE ELECTRICAL CONDUCTORS; PROVIDING A PATTERN OF A THIN PHOTOCONDUCTIVE COATING MATERIAL ADJACENT SAID PLANAR SURFACE, SUCH PATTERN COMPRISING A FIRST ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING BETWEEN AND OVERLAPPING SAID FIRST BUS BAR AND FIRST ENDS OF SAID DISCRETE CONDUCTORS TO FORM A FIRST ROW OF DISCRETE PHOTOCONDUCTIVE CELLS ISOLATED FROM EACH OTHER, AND SUCH PATTERN ALSO INCLUDING A SECOND ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING BETWEEN AND OVERLAPPING SAID SECOND BUS BAR AND SECOND ENDS OF SAID DISCRETE CONDUCTORS TO FORM A SECOND ROW OF DISCRETE PHOTOCONDUCTIVE CELLS ISOLATED FROM EACH OTHER AND ADJACENT THE ENDS OF THE INDIVIDUAL FIBERS OF SAID FIBER OPTIC BUNDLE MEMBER; PROVIDING FIRST AND SECOND ELECTRICAL LEADS CONNECTED TO SAID FIRST AND SECOND BUS BARS RESPECTIVELY TO SUPPLY ELECTRICAL CONTROL CURRENT TO SAID BUS BARS; ENCAPSULATING THE COMPONENTS PROVIDED ADJACENT SAID PLANAR SURFACE, EXCEPTING THE FREE ENDS OF SAID ELECTRICAL LEADS AND A SELECTED AREA IN THE VICINITY OF THE CENTER OF EACH OF SAID DISCRETE ELECTRICAL CONDUCTORS, WITH A THIN SMOOTH LAYER OF A DIELECTRIC MATERIAL TO PROTECT THE ENCAPSULATED COMPONENTS; AND DEPOSITING A DURABLE ELECTRICALLY CONDUCTING MATERIAL UPON SAID SELECTED AREA OF EACH OF SAID DISCRETE ELECTRICAL CONDUCTORS TO FORM ELECTROSTATIC PRINTING CONTACTS, THE SUMMIT OF THE EXPOSED SURFACE OF EACH SUCH PRINTING CONTACT BEING SUBSTANTIALLY EVEN WITH THE SUMMIT OF THE EXPOSED SURFACE OF SAID LAYER OF DIELECTRIC MATERIAL.

Claim 2

THE METHOD OF FABRICATING A CONTROL UNIT FOR ELECTROSTATIC IMAGE RECORDING APPARATUS, SUCH METHOD COMPRISING; PROVIDING A LONGITUDINAL LAMINATED BASIC SUPPORT WHICH INCLUDES A FIRST FIBER OPTIC BUNDLE MEMBER SANDWICHED BETWEEN A SECOND AND A THIRD SUPPORT MEMBER, AT LEAST SUCH SECOND SUPPORT MEMBER BEING DIELECTRIC AND TRANSPARENT AND AT LEAST ONE LONGITUDINAL SURFACE OF EACH OF SUCH THREE MEMBERS EXTENDING IN THE SAME PLANE TO FORM A COMMON PLANAR SURFACE HAVING THE INDIVIDUAL FIBER OPTICS OF SAID FIRST MEMBER DISPOSED NORMAL TO SUCH SURFACE; PROVIDING A PATTERN OF A THIN ELECTRICALLY CONDUCTIVE COATING MATERIAL ADJACENT SAID PLANAR SURFACE, SUCH PATTERN COMPRISING FIRST AND SECOND COATED AREAS EXTENDING SUBSTANTIALLY THE FULL LENGTH OF SAID LONGITUDINAL SURFACES OF SAID SECOND AND THIRD SUPPORT MEMBERS RESPECTIVELY TO FORM FIRST AND SECOND BUS BARS RESPECTIVELY, AND SUCH PATTERN ALSO INCLUDING A ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING ADJACENT SAID PLANAR SURFACE BETWEEN SAID BUS BARS AND ISOLATED THEREFROM AND FROM EACH OTHER TO FORM INDIVIDUAL DISCRETE ELECTRICAL CONDUCTORS; PROVIDING A PATTERN OF A THIN PHOTOCONDUCTIVE COATING MATERIAL ADJACENT SAID PLANAR SURFACE, SUCH PATTERN COMPRISING A FIRST ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING BETWEEN AND OVERLAPPING SAID FIRST BUS BAR AND FIRST ENDS OF SAID DISCRETE CONDUCTORS TO FORM A FIRST ROW OF DISCRETE PHOTOCONDUCTIVE CELLS ISOLATED FROM EACH OTHER, AND SUCH PATTERN ALSO INCLUDING A SECOND ROW OF NARROW CLOSELY ADJACENT COATED AREAS EXTENDING BETWEEN AND OVERLAPPING SAID SECOND BUS BAR AND SECOND ENDS OF SAID DISCRETE CONDUCTORS TO FORM A SECOND ROW OF DISCRETE PHOTOCONDUCTIVE CELLS ISOLATED FROM EACH OTHER AND ADJACENT THE ENDS OF THE INDIVIDUAL FIBERS OF SAID FIBER OPTIC BUNDLE MEMBER; PROVIDING FIRST AND SECOND ELECTRICAL LEADS CONNECTED TO SAID FIRST AND SECOND BUS BARS RESPECTIVELY TO SUPPLY ELECTRICAL CONTROL CURRENT TO SAID BUS BARS; ENCAPSULATING THE COMPONENTS PROVIDED ADJACENT SAID PLANAR SURFACE, EXCEPTING THE FREE ENDS OF SAID ELECTRICAL LEADS AND A SELECTED AREA IN THE VICINITY OF THE CENTER OF EACH OF SAID DISCRETE ELECTRICAL CONDUCTORS, WITH A THIN SMOOTH LAYER OF A DIELECTRIC MATERIAL TO PROTECT THE ENCAPSULATED COMPONENTS; AND DEPOSITING A DURABLE ELECTRICALLY CONDUCTING MATERIAL UPON SAID SELECTED AREA OF EACH OF SAID DISCRETE ELECTRICAL CONDUCTORS TO FORM ELECTROSTATIC PRINTING CONTACTS, THE SUMMIT OF THE EXPOSED SURFACE OF EACH SUCH PRINTING CONTACT BEING SUBSTANTIALLY EVEN WITH THE SUMMIT OF THE EXPOSED SURFACE OF SAID LAYER OF DIELECTRIC MATERIAL.
