Definitions

• the present invention relates to devices for analyzing information carriers, in particular bulletins or game receipts, generally used in terminals for taking games, in particular lotto games, the terminals ensuring the development of coded signals. transmitted to a central unit in which the games of the players are stored in memory until the draw.
• Such analysis devices include means for introducing information carriers generally constituted by a document drive roller itself driven by a stepping electric motor or the like and means for reading the information found therein. on the medium which ensure the conversion of this information into signals capable of being converted into digital data and transmitted to the central game management unit for example.
• image detectors comprising, in an elongated housing, a light source intended to illuminate through a transparent wall of said housing, the document to be read and a series of detectors. photosensitive arranged in a row on the return path of the light from the source reflected by the document and passing through the transparent wall of the image detector housing.
• the transparent wall is generally kept applied against the document drive roller in order to allow the information carriers such as bulletins or game receipts, to be driven by said roller in contact with said transparent wall and thus the reading of the information. carried by the supports.
• the image detector must often be removed in order to clean its transparent surface, which leads to immobilization of the apparatus and maneuvers which the attendant for recording game cards is not not always able to perform in good conditions.
• the invention therefore aims to remedy this disadvantage by creating a device for analyzing information or document carriers which is practically never subject to problems of fouling of the light path between the light source and the photosensitive detectors. of its image detector while preventing the document from being in contact with the image detector at the location of the impact of light from the light source.
• a device for analyzing information carriers comprising a document drive roller and an image detector intended to cooperate with the drive roller to ensure the reading the information carried by the documents driven by 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 analyzed document, characterized in that the casing of the image detector is open on its face facing the drive roller and comprises means for applying the documents against the roller and in that it is mounted angularly displaceable ent relative said roller alternately between a document reading position applied against the roller and a document admission position spaced from said roller.

• Fig.l shows very dry atically a device for analyzing information carriers, in particular documents, such as game cards or receipts comprising a document drive roller 1, driven in rotation by a motor electric step by step 2, via a gear reducer 3.
• the drive roller 1 is associated with an image detector 4 which comprises, in a box 5 of generally elongated parallelepiped shape, a light source 6 constituted for example by a row of light-emitting diodes the number of which depends on the horizontal resolution and of the light intensity required, said source being placed in an inclined position by relative to the median plane of the housing 5 and fixed on a support 7 integral with this housing.
• a light source 6 constituted for example by a row of light-emitting diodes the number of which depends on the horizontal resolution and of the light intensity required, said source being placed in an inclined position by relative to the median plane of the housing 5 and fixed on a support 7 integral with this housing.
• the rays emitted by the source 6 are directed towards an open face 8 of the box in the direction of the documents D to be read which are presented to the device and the rays reflected by a document D, are directed towards photosensitive elements 9 by means of conduc ⁇ light sensors 10 for transmitting beams to said photosensitive elements 9.
• the housing 5 of the image detector 4 is mounted angularly movable relative to the roller 1 for driving the documents, around a fixed hinge axis 11.
• a shoe 14 for example of foam of roughly prismatic shape, one face 15 of which faces the roller 1 has a shape complementary to that of the roller.
• the shoe 14 is mounted in a groove 16 provided in the corresponding edge of the housing 5 above the support 7 for the light source 6.
• the housing 5 of the image detector 4 carries rollers 17 mounted on the fixed axis 11 of articulation of the housing 5 and intended to cooperate with the drive roller 1 to ensure the drive of the documents D as well as their application against the roller 1.
• the shoe 14 also contributes to the application by tension of the documents D against the roller 1 when the image detector 4 is in the reading position, that is to say in the position applied against the roller 1. This tension allows more to obtain a perfectly regular surface even if the document introduced has flatness defects such as folds, creases or the like.
• a mechanism 18 comprising a lever 19 mounted oscillating about a fixed axis 19a and connected to the housing 5 by a link 19b articulated on the lever 19 by a light 19c cooperating with a finger 19d carried by the lever 19, as shown in Fig.la.
• the lever 19 has at one end a cam follower 20 cooperating with a cam surface 21 carried by the end of the plunger core 22 of an electromagnet 23 for controlling the movement of the lever 19.
• the lever 19 carries fingers 24 for orientation of the documents D presented to the reading device when the image detector is in the separated position relative to the drive roller 1, the fingers 24 being retractable when the detector is in reading position applied against roller 1.
• the lever 19 is associated with a spring 25 for returning to the retracted position of the fingers 24.
• the actuating electromagnet 23 is controlled at the rate of passage of the documents D presented to the device, from control signals produced by control means not shown and which are transmitted to the electromagnet 23 via an amplifier 30 and a power transistor 31, and alternately ensures the displacement of the image detector 4, around of the fixed axis 11, in the document reading position applied against the roller 1 and in the document admission position separated from the roller 1.
• the electric motor 2 is controlled by signals also produced by control means not shown and transmitted to said motor by the intermediary of an amplifier 32 and the light source 6 receives control signals by the intermediary of an amplifier 33.
• the device is shown in the position of rest, reception or admission of a document D.
• the pad 14 of the image detector 4 is moved away from the roller 1 and thus provides an entry for the document D, while the fingers 24 integral with the lever 19, are engaged in the intervals formed between the rollers 17 and thus ensure the guiding of the documents D which are presented in the interval between the pad 14 and the roller 1.
• the fingers 24 have a slightly curved shape.
• the electromagnet 23 receives a closing control signal and its plunger 22 during its displacement in translation pushes the cam follower 20 and displaces angularly the lever 19 around the axis 19a towards its position shown in Fig.2.
• This angular displacement of the lever 19 also causes the angular displacement of the housing 5 of the image detector 4 around the fixed axis 11 so as to make it occupy the reading position shown in FIG. 2, in which it can be seen that the shoe 14 applied against the roller 1 and the rollers 16 contribute to the application and tension of the document D against the roller 1.
• the guide fingers 24 being in a retracted position, do not obstruct the propagation of the light rays emitted by the source 6, so that these can be reflected by the document D and returned to the photosensitive elements 9 by the light conductors 10.

• Fig.2 integral with the end walls of the housing 5 and are arranged at regular intervals so as to allow the guide fingers 24 carried by the lever 19 to pass.
• the image detector 4 is mounted in a cover 37 articulated on the rest of the housing 38 of a gaming terminal, for example, and defines with that here a slot 39 for introducing the documents D to be examined.
