Abstract
Abstract Apparatus for optically encoding an item and verifying same, generally including a rotatable index table for sequentially accepting items and carrying each item to a first station where direct printout photosensitive material is applied to a predetermined portion of the item by spraying, to a second station where an optical code image is formed by ultraviolet radiation impinging on a plurality of piezoelectric elements and projected onto the photosensitive material and printed out thereon. The item is then rejected from the table and preferably read at a verification station to verify the accuracy of the encoded data.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
An apparatus for photographically encoding an item with visual intelligence, comprising: a rotatably mounted index table for receiving such item to be encoded; a first station having means for applying a coating of direct printout photosensitive material to a predetermined area of such item; a second station having means for determining and optically projecting said intelligence onto said coating of photosensitive material to produce a direct printout image of said intelligence on such item; and means for rotating said table to sequentially position such item at said first station and said second station, said rotating means including means for ejecting such item from said table after said intelligence has been projected onto such item.
Claim 2
Independent Claim
114 words
An apparatus for photographically encoding an item with visual intelligence, comprising: a rotatably mounted index table for receiving such item to be encoded; a first station having means for applying a coating of direct printout photosensitive material to a predetermined area of such item; a second station having means for determining and optically projecting said intelligence onto said coating of photosensitive material to produce a direct printout image of said intelligence on such item; and means for rotating said table to sequentially position such item at said first station and said second station, said rotating means including means for ejecting such item from said table after said intelligence has been projected onto such item.
Claim 3
Dependent Claim
22 words
The invention of claim 1 including means for optically reading said intelligence on such item to verify the accuracy of said intelligence.
Claim 4
Dependent Claim
27 words
The invention of claim 2 wherein said reading means is positioned to read said intelligence on such item as such item is ejected from said index table.
Claim 5
Dependent Claim
30 words
The inventioN of claim 1 wherein said applying means includes means for spraying a coating of direct printout photosensitive material onto such item in said predetermined area of such item.
Claim 6
Dependent Claim
36 words
The invention of claim 1 wherein said first station includes means for registering such item relative to said applying means to insure that said photosensitive material is accurately coated on said predetermined area of such item.
Claim 7
Dependent Claim
36 words
The invention of claim 4 wherein said first station includes means for registering such item relative to said spraying means to insure that said photosensitive material is accurately sprayed on said predetermined area of such item.
Claim 8
Dependent Claim
47 words
The invention of claim 1 wherein said determining and projecting means includes: means for producing a beam of ultraviolet radiation; piezoelectric means for modulating said beam to form a pattern representing said intelligence; and means for optically projecting said pattern onto said predetermined area of such item.
Claim 9
Dependent Claim
17 words
The invention of claim 7 including means for electrically controlling said piezoelectric means to form said pattern.
Claim 10
Dependent Claim
18 words
The invention of claim 7 wherein said direct printout photosensitive material is sensitive in the ultraviolet region only.
