BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to devices for analysing information carriers, especially gaming tickets or receipts, generally used in gaming input terminals, especially for lottery games, the terminals formulating coded signals transmitted to a central unit in which the bets of the players are stored in memory until the draw.
Such analysers comprise means for inserting information carriers generally consisting of a document drive roller which is itself driven by an electric stepper motor or the like, and means for reading the information on the carrier which convert this information into signals capable of being converted into digital data and transmitted to the central gaming management unit for example.
Among the known information-reading means, mention may be made of image detectors comprising, in a case of elongate shape, a light source intended to illuminate, through a transparent wall of the said case, the document to be read and a series of photosensitive detectors placed in a row in the return path of the light from the source reflected by the document and passing through the transparent wall of the case of the image detector.
The transparent wall is generally held applied against the document drive roller so as to enable the information carriers, such as gaming tickets or receipts, to be driven by the roller in contact with the transparent wall and thus to enable the information carried by the carriers to be read.
Although such an arrangement often gives excellent results, the roller has, however, the drawback of being exposed to the risk of becoming frequently fouled, since the analysers are generally used in places where the image detector is exposed to the risk of picking up dust, traces of ink or eraser residues resulting, for example, from alteration of gaming tickets by the player at the last moment, when inserting his ticket into the analyser.
As a result, the image detector must be frequently removed in order to clean its transparent surface, which leads to periods when the apparatus is out of action and to operations which the official responsible for recording the gaming tickets is not always capable of carrying out under the correct conditions.
SUMMARY OF THE INVENTION
The invention therefore aims to remedy this drawback by creating a device for analyzing information carriers or documents which is virtually never subject to the problems of fouling of the light path between the light source and the photosensitive detectors of its image detector while at the same time preventing the document from coming into contact with the image detector at the point of impact of the light from the light source.
The subject of the invention is therefore a device for analysing information carriers, especially gaming tickets or receipts, comprising a document drive roller and an image detector intended to interact with the drive roller in order to read the information carried by the documents driven by the said roller, the image detector comprising a light source for illuminating the documents and photosensitive elements, arranged in a row, for reading the information contained in the light emitted by the source and reflected by an analysed document, characterized in that the case of the image detector is open on its face turned towards the drive roller and includes means for applying the documents against the roller and in that it is mounted so that it can move angularly with respect to the roller alternately between a document read position applied against the roller and a document inlet position away from the roller.
