Electroluminescent photocopying

Claim 2

PHOTOCOPYING APPARATUS COMPRISING A FLAT ELECTROLUMINESCENT SHEET, CONVERTER MEANS ADAPTED TO BE CONNECTED TO A SOURCE OF ELECTRICAL ENERGY AND TO CONVERT THE ELECTRICAL ENERGY TO EXCITE SAID ELECTROLUMINESCENT SHEET, CONNECTOR MEANS FOR CONNECTING SAID ELECTROLUMINESCENT SHEET TO SAID CONVERTER, SAID ELECTROLUMINESCENT SHEET BEING ADAPTED TO BE JUXTAPOSED TO A LIGHT-SENSITIVE SHEET CONTIGUOUS WITH AN OBJECT TO BE COPIED TO EXPOSE SAID LIGHT SENSITIVE SHEET AND THEREBY THE OBJECT, SAID CONVERTER INCLUDING OUTPUT SIGNAL FREQUENCY VARYING MEANS OPERATIVE STO VARY SAID CONVERTER OUTPUT SIGNAL FREQUENCY IN ACCORDANCE WITH A DESIRED COLOR OF LIGHT TO BE PRODUCED BY THE ELECTROLUMINESCENT SHEET, THE COLOR OF LIGHT PRODUCED BEING DEPENDENT UPON THE LIGHT SENSITIVITY OF THE LIGHT-SENSITIVE SHEET.

Claim 3

PHOTOCOPYING APPARATUS COMPRISING A BOTTOM SUPPORT HAVING A FLAT RIGID OPAQUE SURFACE, A FLAT RIGID OPAQUE PRESS MEMBER BIASED TOWARD CONTIGUOUS ABUTMENT WITH SAID SURFACE, AN ELECTROLUMIESCENT SHEET, CONNECTING MEANS FOR CONNECTING SAID ELECTROLUMIESCENT SHEET TO A SOURCE OF ALTERNATING CURRENT FOR EXCITING SAID ELECTROLUMINESCENT SHEET, SAID ELECTROLUMINESCENT SHEET BEING ADAPTED TO BE JUXTAPOSED TO SAID LIGHT-SENSITIVE SHEET CONTIGUOUS WITH AN OBJECT TO BE COPIED BETWEEN SAID PRESS MEMBER AND SAID SURFACE TO SAID LIGHT-SENSITIVE SHEET AND THEREBY COPY THE OBJECT, SAID ELECTROLUMINESCENT SHEET CONSISTING OF TWO SEPARATELY EXCITED ELECTROLUMINESCENT LAYERS HAVING A REFLECTIVE COATING THEREBETWEEN, EACH OF THE ELECTROLUMINESCENT LAYERS BEING ADAPTED TO BE JUXTAPOSED TO A LIGHT-SENSITIVE SHEET CONTIGUOUS WITH AN OBJECT TO BE COPIED AND PLACED BETWEEN SAID PRESS MEMBER AND SAID SURFACE TO EXPOSE SAID LIGHT-SENSITIVE SHEETS AND THEREBY COPY THE OBJECTS.

Claim 4

PHOTOCOPYING APPARATUS COMPRISING A BOTTOM SUPPORT HAVING A FLAT RIGID OPAQUE SURFACE, A FLAT RIGID OPAQUE PRESS MEMBER BIASED TOWARD CONTIGUOUS ABUTMENT WITH SAID SURFACE, AN ELECTROLUMIESCENT SHEET, CONNECTING MEANS FOR CONNECTING SAID ELECTROLUMIESCENT SHEET TO A SOURCE OF ALTERNATING CURRENT FOR EXCITING SAID ELECTROLUMINESCENT SHEET, SAID ELECTROLUMINESCENT SHEET BEING ADAPTED TO BE JUXTAPOSED TO SAID LIGHT-SENSITIVE SHEET CONTIGUOUS WITH AN OBJECT TO BE COPIED BETWEEN SAID PRESS MEMBER AND SAID SURFACE TO SAID LIGHT-SENSITIVE SHEET AND THEREBY COPY THE OBJECT, SAID ELECTROLUMINESCENT SHEET CONSISTING OF TWO SEPARATELY EXCITED ELECTROLUMINESCENT LAYERS HAVING A REFLECTIVE COATING THEREBETWEEN, EACH OF THE ELECTROLUMINESCENT LAYERS BEING ADAPTED TO BE JUXTAPOSED TO A LIGHT-SENSITIVE SHEET CONTIGUOUS WITH AN OBJECT TO BE COPIED AND PLACED BETWEEN SAID PRESS MEMBER AND SAID SURFACE TO EXPOSE SAID LIGHT-SENSITIVE SHEETS AND THEREBY COPY THE OBJECTS.
