Abstract

Abstract An imaging device of the present invention, utilized for game cards or the like, comprises an optical validation sensor configured to prevent fraudulent play by a retailer or the like to pick out winning game cards. The optical validation sensor activates the imaging device only upon sensing a predetermined amount or density of light passing through the game card. The imaging device also comprises a debris slot to prevent debris or the like from collecting therein when accompanied with a card being inserted and improved configurations of the game card.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 134 words
An imaging card device, comprising: a receiving means for receiving a card having at least one symbol and at least one area having binary zones representative of said symbol, said binary zones being selectively filled with infrared radiating ink; a strobe light source disposed proximate said receiving means, said strobe light source being adapted to shine visible light onto said card and expose said prize; a code sensor coupled to said receiving means, said code sensor being adapted to read said binary zones to detect the presence and absence of ink and indicate said symbol; and an optical validation sensor disposed proximate said symbol, said optical validation sensor adapted to detect the density of light passing through said card and activate said code sensor only upon detecting density of light over a predetermined threshold.
Claim 2
Dependent Claim 134 words
An imaging card device, comprising: a receiving means for receiving a card having at least one symbol and at least one area having binary zones representative of said symbol, said binary zones being selectively filled with infrared radiating ink; a strobe light source disposed proximate said receiving means, said strobe light source being adapted to shine visible light onto said card and expose said prize; a code sensor coupled to said receiving means, said code sensor being adapted to read said binary zones to detect the presence and absence of ink and indicate said symbol; and an optical validation sensor disposed proximate said symbol, said optical validation sensor adapted to detect the density of light passing through said card and activate said code sensor only upon detecting density of light over a predetermined threshold.
Claim 3
Dependent Claim 29 words
An imaging device as defined in claim 1, wherein said code sensor further comprises: at least one zone sensor positioned to read an individual one of said binary zones.
Claim 4
Dependent Claim 50 words
An imaging device as defined in claim 1, wherein said card comprises: a substrate imprinted with a pattern of infrared radiating ink to form said symbol; and a thermal sensitive layer deposited over said substrate to visually conceal the ink prior to said card being inserted into said receiving means.
Claim 5
Dependent Claim 40 words
An imaging device as defined in claim 3, wherein said light source is adapted to shine visible light through said thermal sensitive layer and onto said pattern, whereby said ink converts visible light into infrared light to expose said pattern.
Claim 6
Dependent Claim 49 words
An imaging device as defined in claim 1, further comprising: a voice unit connected to said code sensor, said code sensor being adapted to actuate said voice unit to announce a message depending upon the presence or absence of ink in the binary zones detected by the code sensor.
Claim 7
Dependent Claim 25 words
An imaging device as defined in claim 2, wherein said zone sensor comprises a means for emitting light and a means for detecting reflected light.
Claim 8
Dependent Claim 19 words
An imaging device as defined in claim 6, wherein said emitting means is at least one light emitting diode.
Claim 9
Dependent Claim 15 words
An imaging device as defined in claim 6, wherein said detecting means is a phototransistor.
Claim 10
Dependent Claim 29 words
An imaging device as defined in claim 1, wherein said receiving means further comprises: a debris slot adapted to receive debris inserted with said card into said receiving means.
Claim 11
Dependent Claim 17 words
An imaging device as defined in claim 1, wherein said binary zones are disposed around said symbol.
Claim 12
Dependent Claim 222 words
An imaging game card device, comprising: receiving means; a card for insertion into said receiving means, comprising: a substrate imprinted with a pattern of infrared radiating ink indicating a prize and binary zones denoting a code corresponding to said prize, said binary zones selectively filled with infrared ink; and a thermal sensitive layer deposited over said substrate to visually conceal said infrared ink prior to said card being inserted into said receiving means; a light source disposed proximate said receiving means, said light source being adapted to shine visible light through said thermal sensitive layer and onto said pattern, whereby said ink converts visible light into infrared light to expose said prize and said code; a code sensor disposed proximate said receiving means, said code sensor being adapted to read said binary zones to detect the presence and absence of ink; a voice unit connected to said code sensor, said code sensor being adapted to actuate said voice unit to announce said prize corresponding to the presence or absence of ink detected by the sensor in the binary zones; and an optical validation sensor disposed proximate said pattern of infrared radiating ink, said optical validation sensor adapted to detect the density of light passing through said card and activating said code sensor only upon detecting density of light over a predetermined threshold.
Claim 13
Dependent Claim 222 words
An imaging game card device, comprising: receiving means; a card for insertion into said receiving means, comprising: a substrate imprinted with a pattern of infrared radiating ink indicating a prize and binary zones denoting a code corresponding to said prize, said binary zones selectively filled with infrared ink; and a thermal sensitive layer deposited over said substrate to visually conceal said infrared ink prior to said card being inserted into said receiving means; a light source disposed proximate said receiving means, said light source being adapted to shine visible light through said thermal sensitive layer and onto said pattern, whereby said ink converts visible light into infrared light to expose said prize and said code; a code sensor disposed proximate said receiving means, said code sensor being adapted to read said binary zones to detect the presence and absence of ink; a voice unit connected to said code sensor, said code sensor being adapted to actuate said voice unit to announce said prize corresponding to the presence or absence of ink detected by the sensor in the binary zones; and an optical validation sensor disposed proximate said pattern of infrared radiating ink, said optical validation sensor adapted to detect the density of light passing through said card and activating said code sensor only upon detecting density of light over a predetermined threshold.
