Abstract
Abstract A device for analyzing information carriers, particularly gaming coupons or receipts, includes a carrier receiver device, an image scanning device for reading the information on the carrier, a processing unit for processing the image information and for transmitting the information to a central gaming management unit. The carrier is printed with multiple colors. The image scanning device includes an optical reader which is blind to a single color, but sensitive to all other colors. The carrier has fixed marking patterns, printed in the color to which the image scanning device is blind, which delineate where the player marks the carrier with variable gaming information. The carrier also has fixed information for alignment and type designation printed in other colors. The processing unit uses stored marking patterns corresponding to the type of carrier analyzed, by superimposing blind color information.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A device for analyzing information carriers, especially gaming coupons or receipts, comprising: means for inserting the carrier; means for reading the information on the carrier; and means for processing the information read from the carrier with a view to its conversion into digital data and its transmission to a central gaming management unit, wherein the means for reading the information on the carrier comprise an optical reader which is blind to a single color for the whole of the analysis and in which color fixed information is printed on the coupon and which the reader is sensitive to other colors, so as to take into account only the variable gaming information and the fixed information for aligning the coupon and for designating the type of game to which it belongs, which information is printed in these other colors and in that, the processing means comprise, for analyzing gaming coupons, means of generating marking patterns corresponding to the type of game to which the coupon belongs with a view to the reconstructing of the coupon's regions to be analyzed by superimposing on the variable data and on the fixed alignment and game type data, fixed marking patterns data to which the image reader has been rendered blind.
Claim 2
Independent Claim
206 words
A device for analyzing information carriers, especially gaming coupons or receipts, comprising: means for inserting the carrier; means for reading the information on the carrier; and means for processing the information read from the carrier with a view to its conversion into digital data and its transmission to a central gaming management unit, wherein the means for reading the information on the carrier comprise an optical reader which is blind to a single color for the whole of the analysis and in which color fixed information is printed on the coupon and which the reader is sensitive to other colors, so as to take into account only the variable gaming information and the fixed information for aligning the coupon and for designating the type of game to which it belongs, which information is printed in these other colors and in that, the processing means comprise, for analyzing gaming coupons, means of generating marking patterns corresponding to the type of game to which the coupon belongs with a view to the reconstructing of the coupon's regions to be analyzed by superimposing on the variable data and on the fixed alignment and game type data, fixed marking patterns data to which the image reader has been rendered blind.
Claim 3
Dependent Claim
99 words
The device according to claim 1, wherein tile optical reader comprises: a linear light source, extending over the transverse dimension of the document to be analyzed and photosensitive elements situated in the path of the light emitted by the source and reflected by the document to be analyzed, characterized in that the light source comprises a single monochromatic light source whose color is that in which the fixed information not having to be taken into account by the device is printed, the source illuminating the whole of the document independently of the function of the information which it bears.
Claim 4
Dependent Claim
20 words
The device according to claim 2, wherein the monochromatic light source comprises a series of light-emitting diodes emitting monochromatic beams.
Claim 5
Dependent Claim
50 words
The device according to claim 3, wherein the light-emitting diodes there are associated filtering and focusing elements consisting of thick lenses ensuring the overlapping between beams exiting from neighboring lenses so that the light emitted by the series of light-emitting diodes has the appearance of a continuous monochromatic luminous stroke.
Claim 6
Dependent Claim
47 words
The device according to claim 2, wherein the monochromatic light source consists of at least one discharge tube emitting in the color to which the device is blind and associated with a filter arranged in the path of the light between the source and the photosensitive elements.
Claim 7
Dependent Claim
26 words
The device according to claim 1, wherein tile processing means further comprises, means of reading bar codes corresponding to the validation numerals of the gaming coupons.
Claim 8
Dependent Claim
139 words
The device according to claim 1, further comprises: means for detecting the presence and the nature of the documents presented to the analysis device, wherein the means consist of at least two detectors arranged at a distance slightly greater than the dimension transverse to the direction of displacement of the document of smaller dimension to be analyzed, a detector being actuated by a document of smaller dimension and at least two detectors being actuated by a document of larger dimension, and in that the detectors are connected to a circuit for monitoring the control signals of the stepper motor for driving the roller of the analysis device and signals corresponding to the dimension and consequently to the nature of the document presented to the device with a view to the employing of corresponding means contained in the processing means.
Claim 9
Dependent Claim
60 words
The device according to one of claim 1, wherein the axis of the roller and the optical axis of the light conductors have an offset in the direction of insertion of a document in order to allow the front edge of this document to reflect the light emitted by the monochromatic light source, thus indicating the presence of the document.
Claim 10
Dependent Claim
100 words
The device according to claim 2, further comprising: means for monitoring the parallelism of the edge of the document and of the linear light source by determining a minimum number of photosensitive elements having to receive the light reflected by the edge of the document or else a minimum distance between two illuminated photosensitive elements when placing the document in the device and for controlling the processing means so that they actuate the electric stepper motor for driving the roller when the monitoring of the parallelism indicates that the defect in parallelism between the document and the source is tolerable.
Claim 11
Dependent Claim
54 words
The device according to one of claim 2, further comprising: means for monitoring the luminous intensity of the light source, which means are connected up to the processing means, itself linked to a comparator between a read signal relating to the brightness of the source and a threshold signal delivered by a signal source.
