Multiple copy electrostatic imaging apparatus

Claim 1

APPARATUS FOR ESTABLISHING POTENTIAL VIBRATIONS IN A PIN MATRIX IN ACCORD WITH AN OPTICAL INPUT SUPPLIED TO SAID APPARATUS COMPRISING: (A) A SEMICONDUCTOR FIELD EFFECT LAYER DIVIDED INTO PAIRED ADJACENT AREAS, THE FIRST MEMBER OF EACH OF SAID PAIRS BEING RESPONSIVE TO LIGH IMPINGING THEREON BY DISSIPATING PREVIOUSLY DEPOSITED CHARGE IN ACCORDANCE WITH THE INTENSITY OF SAID LIGHT, WHEREBY A CHARGE PATTERN MAY BE ESTABLISHED ON THE TOTALITY OF SAID FIRST MEMBER AREAS IN ACCORD WITH SAID OPTICAL INPUT PATTERN AND WHEREBY CONDUCTIVITY VARIATIONS MAY BE ESTABLISHED IN THE SEMICONDUCTOR VOLUMES UNDERLYING SAID FIRST MEMBER AREAS IN ACCORD WITH SAID OPTICAL INPUT; (B) A MATRIX OF CONDUCTIVE PINS, INDIVIDUAL PINS BEING ELECTRICALLY CONNECTED TO THE BOUNDARIES BETWEEN SAID PAIRED AREAS; (C) MEANS TO ESTABLISH AN ELECTRICAL POTENTIAL BETWEEN MEMBERS OF SAID PAIRS WHEREBY EACH OF SAID PINS APEARS ELECTRICALLY AT THE DIVISION POINT OF SAID PINS DIVIDER CIRCUIT INCLUDING IN SERIES CONNECTION A CONCONDUCTIVE CHANNEL IN SAID FIRST MEMBER AREA DISPLAYING FIXED CONDUCTIVITY REPRESENTATIVE OF THE INTRINSIC CONDUCITIVITY SAID SEMICONDUCTOR AND A CONDUCITIVITY CHANNEL IN SAID SECOND MEMBER AREA DISPLAYING CONDUCTIVITY IN ACCORD WITH THE CHARGE PATTERN THEREON, WHEREBY THE ELECTRICAL POTENTIAL OF INDIVIDUAL OF SAID PINS VARIES IN ACCORD WITH THE CONDUCTIVITY OF SAID FIRST MEMBER AREAS AND THUS IN ACCORD WITH SAID OPTICAL INPUT.
