And the rotation of the reel is stopped based on the timing of the stop operation. Then, when the rotation of all the reels is stopped and the symbol combination related to the winning is displayed, a privilege corresponding to the symbol combination is given to the player.

  Such a gaming machine is provided with a medal selector for detecting a medal inserted into the medal slot. Here, a medal is inserted into a typical goth act among the cheating acts on the gaming machine (so-called goth act) by inserting a cheating device from the medal slot and operating the counting function of the medal selector illegally. There is something that looks like you get a lot of credit. Also, for example, in a hall where a slot machine is installed, a low-bet gaming machine called a so-called 5-thro that can be played with a 5-yen medal and a normal gaming machine that can be played with a 20-yen medal (so-called 20 slots) may be installed. In such a hole, a medal acquired with 5 slots can be used with 20 slots, and the person who performs the fraudulent act that illegally acquires the difference ((20 yen-5 yen) x the number of owned pieces) can be damaged. Has occurred. In gaming machines, measures are taken against such goto acts.

  For example, in Patent Document 1, two medal detection proximity sensors are provided in a medal passage, and it is determined whether a game medal has passed through the medal passage based on the output of each proximity sensor. A slot machine for detecting fraud using a device such as a body is disclosed.

  Further, in Patent Document 2, a first image group composed of a plurality of template images after geometric transformation having different amounts of geometric transformation is generated by applying geometric transformation to the template image, and eigenvalue decomposition is performed to generate a unique image. By calculating the function and performing these inner product operations, the second image group is generated, and the image similarity between the input image and the second image group is calculated, so that the object is correct in the image processing. Techniques for determining whether or not are disclosed.

JP 2002-342814 A Japanese Patent No. 5317250

  In a conventional gaming machine such as the slot machine described in Patent Document 1, it is determined whether or not the inserted medal is a regular medal. If it is determined that the medal is not a regular medal, the medal is determined. It is configured to prevent the use of illegal medals by playing. In the determination of medals, for example, image processing is performed such that the inserted medals are imaged with a camera, and the medal image captured using the technique described in Patent Document 2 is compared with the correct medal image. Is called. In order to play a medal, for example, a method is used in which a solenoid is driven to drive a medal pressure into a medal rail that is a medal passage, and the medal pressure is used to eject the medal from the medal reel and return it to the medal return port. ing.

  Therefore, in order to reliably play an illegal medal, the medal judgment and the solenoid drive must be performed within a very short time after the medal is inserted and moved to the medal pressure position along the medal rail in the gaming machine. Must be executed.

  However, in the conventional gaming machine, it is necessary to secure time for driving the solenoid under such time constraints, and the medal determination time is limited accordingly, so the medal determination accuracy is limited, There is a problem that all illegal medals that should be played cannot be played.

  It is an object of the present invention to shorten the solenoid drive time, ensure sufficient medal determination time and improve medal determination accuracy, thereby misrecognizing that a legitimate game medium is used and playing a game It is an object of the present invention to provide a gaming machine or a gaming apparatus that can detect the above with high accuracy.

[One Embodiment of the Present Invention]
Hereinafter, a pachislot machine that is a gaming machine according to an embodiment of the present invention will be described with reference to FIGS.

<Function flow>
First, the functional flow of the pachislot will be described with reference to FIG.
In the pachislot of this embodiment, medals are used as game media for playing games. In addition to the medals, coins, game balls, game point data, tokens, or the like can be applied as game media.

  When a player inserts a medal and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means performs lottery based on the extracted random number value and determines an internal winning combination. This internal lottery means is carried out by a main control circuit described later. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which benefits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Further, when the start lever is operated, a plurality of reels are rotated. Thereafter, when the player presses the stop button corresponding to the predetermined reel, the reel stop control means performs control to stop the rotation of the corresponding reel based on the internal winning combination and the timing when the stop button is pressed. Do. The reel stop control means is responsible for a main control circuit described later.

  In the pachislot, basically, a control for stopping the rotation of the corresponding reel is performed within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”. When the specified period is 190 msec, the maximum number of sliding symbols is set to 4 symbols, and when the specified period is 75 msec, the maximum number of sliding symbols is set to 1 symbol.

  When the internal winning combination allowing the symbol combination display related to winning is determined, the reel stop control means usually displays the symbol combination within the specified time of 190 msec (four symbols) for the winning determination line. The rotation of the reel is stopped so as to display as much as possible. In addition, the reel stop control means is defined for one or more reels when, for example, a challenge bonus (CB), which is a second-type special accessory, and a middle bonus (MB) for continuously operating the CB are operated. The reel rotation is stopped so that the combination of symbols is displayed as much as possible along the winning determination line within a time of 75 msec (for one symbol). Furthermore, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination line. Stop.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. This winning determination means is carried out by a main control circuit described later. When it is determined by the winning determination means that it is related to winning, a privilege such as paying out medals is given to the player. In the pachislot, a series of flows as described above is performed as one game.

  Also, in the pachislot, in the above-described series of flows, video display performed by a display device such as a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof is used. Various productions are performed.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random number value used for determining the internal winning combination. When the effect random number value is extracted, the effect content determining means determines, by lottery, what is to be executed this time from among a plurality of types of effect contents associated with the internal winning combination. This effect content determination means is carried out by a sub-control circuit described later.

  When the contents of the effect are determined, the effect executing means executes the corresponding effect in conjunction with each opportunity, such as when the rotation of the reels starts, when the rotation of each reel stops, or when determining whether there is a winning. In this way, in the pachislot machine, the player has the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. It is possible to improve the player's interest.

  As shown in FIG. 9, the after-medal pressure 218 has a front end portion rotatably supported on a shaft portion 218 a provided on the front surface 204 a of the base plate portion 204. The after medal pressure 218 is urged by a coil spring provided in the shaft portion 218a so that the rear end portion does not protrude from the upper exposed hole 219 (see FIG. 8) into the medal rail 210 (rear surface 204b side). Yes. Then, when the front end of the after-medal pressure 218 is pressed rearward (rear side 204b side) of the pachislot 1 by the medal solenoid 208, the rear end is rotated from the upper exposure hole 219 to the medal. It is exposed in the rail 210 (rear surface 204b side).

  As shown in FIG. 8, the sub plate 205 is a plate-like member provided at a position overlapping the medal rail 210. The sub-plate 205 has a flat plate-like main body part 221, a shaft part 222 provided on the upper part of the main body part 221, and an attachment member 272 for attaching a first light guide 261 described later. . A substantially central portion of the main body 221 is provided with a through hole 221a that is disposed behind the position including the central hole 212, the upper exposed hole 219, and the lower exposed hole 220 of the medal rail 210 and penetrates in the front-rear direction. From the through hole 221a, a downstream region is exposed from a substantially central portion of the medal rail 210, and a maximum imageable region of the camera unit 209 described later is formed.

  The shaft portion 222 is supported by the base plate portion 204, and the sub-plate 205 is attached to the base plate portion 204 so as to be rotatable about the shaft portion 222. A coil spring 223 is attached to the shaft portion 222. Under normal conditions, the sub plate 205 is pressed against the base plate portion 204 side by the biasing force of the coil spring 223. At this time, a space through which medals can pass is formed between the sub plate 205 and the upper part of the medal rail 210 covered with the sub plate 205. That is, the sub plate 205 functions as a guide plate that allows the medal to pass therethrough.

The cancel shooter 206 is disposed behind the sub-plate 205 so as to face the medal rail 210, and has a plate-like intermediate member 293 that holds the camera unit 209, the wiring board 288, and the like, and a cover member 294 that covers the intermediate member 293.

FIG. 10 is an exploded perspective view of the cancel shooter 206 as viewed from diagonally forward of the pachi-slot 1.
The intermediate member 293 of the cancel shooter 206 is formed with an opening 293a that becomes an opening region of the camera unit 209. The opening area of the opening 293a is an area that does not interfere with the angle of view in the vicinity of the lens 283 (see FIG. 18 described later) of the camera unit 209 in order for the camera unit 209 to capture the shooting area RLa (see FIG. 25 described later). It is formed with.

  FIG. 11 is a cross-sectional view of a portion where the opening 293a of the intermediate member 293 is formed. In FIG. 11, for ease of understanding, the camera unit 209 (acrylic resin mounting unit 296, lens protection cover 295, lens holder 275, lens unit 287, and wiring board disposed in the vicinity of the opening 293a of the intermediate member 293 is shown. 288) is indicated by a dotted line. The camera unit 209 (acrylic resin mounting unit 296, lens protective cover 295, lens holder 275, lens unit 287, and wiring board 288) will be described later.

  The intermediate member 293 protrudes from the surface opposite to the medal rail 210 (see FIG. 8) (direction B in FIG. 11) at the periphery of the opening 293a, and is an offset portion as a protrusion where the camera unit 209 is disposed. 293b is formed. An acrylic resin mounting unit 296, which will be described later, is fixed to the offset portion 293b with an acrylic resin plate 296a formed of a translucent material interposed therebetween, and closes the opening portion 293a. A lens unit 287 and a lens protection cover 295 are disposed on the surface of the acrylic resin plate 296a opposite to the opening 293a (direction B in FIG. 11). In other words, the acrylic resin plate 296a as a translucent plate is disposed between the intermediate member 293 as the holding means and the camera unit 209 as the imaging means, and closes the opening 293a. In the present embodiment, the camera unit 209 constitutes a detection unit that detects a medal inserted into the pachislot 1 by capturing an image of the medal.

  Further, the intermediate member 293 is inclined toward the outside from the center of the opening 293a toward the direction (F direction in FIG. 11) in which the medal rail 210 (see FIG. 8) is arranged at the periphery of the opening 293a. The taper processing is done. As described above, the intermediate member 293 has the inner dimension 293a ′ of the opening 293a gradually widening toward the medal rail 210.

  As described above, the offset portion 293b is formed on the surface opposite to the medal rail 210 (see FIG. 8) through which the medal passes at the periphery of the opening portion 293a serving as the opening region of the camera unit 209, and the camera is formed on the offset portion 293b. By disposing the unit 209, the camera unit 209 and the medal rail 210 can be further separated from each other, and the imaging range that can be captured by the camera unit 209 is widened. Therefore, a medal passing through the passage can be imaged in a wider range. Accordingly, a gaming machine capable of ensuring a captureable range necessary for accurately detecting an illegal act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine based on the captured image. Can be provided. Further, by forming the offset portion 293b at the periphery of the opening 293a, the strength of the intermediate member 293 is improved, the intermediate member 293 is bent, and the optical axis of the camera unit 209 held by the intermediate member 293 is displaced, It is possible to prevent a medal from being imaged at an appropriate position and to prevent the accuracy of detecting fraud.

  Further, since the inner dimension 293a ′ is tapered on the periphery of the opening 293a toward the medal rail 210 (see FIG. 8), the edge of the opening 293a on the medal rail 210 side is captured by the camera unit 209. It is possible to prevent the range in which the medal passing through the medal rail 210 from being taken into the range can be captured. Further, by tapering the peripheral medal rail 210 side of the opening 293a, when a medal passing through the medal rail 210 falls to the intermediate member 293 side and comes into contact with the peripheral edge of the opening 293a, the medal is smoothly Can be carried away. Therefore, it is possible to prevent the medal from being clogged in contact with the peripheral edge of the opening 293a, the medal cannot be imaged at an appropriate position, and the accuracy of detecting fraud can be prevented from being lowered. Further, at least the lower peripheral edge in the vertical direction on the peripheral medal rail 210 side of the opening 293a is tapered, so that foreign matters such as dust can be prevented from accumulating on the lower peripheral edge of the opening 293a. Therefore, it is possible to prevent the foreign matter from collecting around the periphery of the opening 293a and being picked up by the image pickup means together with the passing object, thereby reducing the accuracy of detecting fraud. Therefore, it is possible to secure the imageable range necessary for detecting a fraudulent act of playing a game by misidentifying that a legitimate game medium is used in the gaming machine with high accuracy based on the captured image. A gaming machine that can prevent an appropriate image from being captured can be provided.

  In addition, since the acrylic resin plate 296a that closes the opening 293a is disposed between the intermediate member 293 and the camera unit 209, foreign matter such as dust is introduced into the camera unit 209 from the medal rail 210 (see FIG. 8) side. Intrusion can be prevented. Accordingly, it is possible to prevent foreign matter from entering the camera unit 209, preventing the camera unit 209 from appropriately capturing medals, and reducing the accuracy of detecting fraud. Even if such foreign matter adheres to the acrylic resin plate 296a, the camera unit 209 is focused on the medal rail 210, so that the position of the acrylic resin plate 296a to which the foreign matter has adhered is the camera unit 209. Therefore, the influence of the camera unit 209 on the imaging of medals is small. Therefore, it is possible to secure the imageable range necessary for detecting a fraudulent act of playing a game by misidentifying that a legitimate game medium is used in the gaming machine with high accuracy based on the captured image. A gaming machine that can prevent an appropriate image from being captured can be provided.

  Returning to FIG. 8, one end of a harness (not shown) is connected to the wiring board 288 provided in the cancel shooter 206, and this harness extends from the cancel shooter 206 to the outside, and the other end is a door described later. It is connected to the relay terminal board 68 (see FIG. 30). Therefore, a harness receiving portion 293c is formed on the intermediate member 293 as a configuration for fixing such a harness near the end of the cancel shooter 206, and the cover member 294 corresponds to the harness receiving portion 293c.

In FIG. 12, an alternate long and short dash line indicates the harness H, and a broken line indicates a path B through which a binding band that is a band-shaped binding member for binding the harness is inserted. The intermediate member 293 has a harness receiving portion 293c in which a harness H extending in a predetermined direction is disposed. The harness receiving portion 293c includes an arrangement surface 293d on which the harness H is arranged, a side edge of the arrangement surface 293d, protrudes away from the arrangement surface 293d, and a approach surface 293e that brings the harness H toward the arrangement surface 293d. . The harness receiving portion 293c is formed with a groove 293f that extends in a direction orthogonal to a predetermined direction in which the harness H extends and in which a binding band (not shown) that binds the harness H is disposed. The groove 293f is formed by cutting out the surfaces of the arrangement surface 293d and the approach surface 293e, and in the direction orthogonal to the predetermined direction in which the harness H extends, from the center side to the end side (from the arrangement surface 293d side) of the harness receiving portion 293c. It has an inclined portion 293g that is inclined upward on the approaching surface 293e side. The side surface of the groove 293f forms a wall for preventing the binding band from falling off the groove 293f, and both ends of the groove 293f are formed at positions facing a pair of through holes 294b of a cover member 294 described later. . The inclination angle of the inclined portion 293g is such that the binding band inserted into one of the through holes 294b of the cover member 294 is bent and the other through hole 294b is easily inserted into the outside of the cover member 294. Yes. In addition, since the binding band in this embodiment is formed with the general nylon raw material, it has the flexible flexibility to a binding direction.

  Further, the intermediate member 293 includes a proximal end pressing portion 293h formed on the proximal end side (in the direction of the wiring board 288) of the harness H from the harness receiving portion 293c. The proximal end pressing portion 293h extends in a direction orthogonal to a predetermined direction in which the harness H extends at a position away from the arrangement surface 293d by a predetermined dimension in a direction orthogonal to the arrangement surface 293d of the harness receiving portion 293c. In addition, the proximal end side pressing portion 293h has a hook portion 293i that is provided at the end thereof and protrudes toward the arrangement surface 293d in the direction orthogonal to the arrangement surface 293d.

  Thereby, since the base end side of the harness H arrange | positioned at the harness receiving part 293c can be hold | suppressed with the base end side holding | suppressing part 293h, for example, when the harness H is pulled, the harness H is pressed to the base end side. It is possible to prevent the connecting portion of the harness H (the connector of the wiring board 288) from being pulled and pressed by the portion 293h and being damaged. Further, for example, at the time of assembly, the harness H is inserted between the harness receiving portion 293c and the proximal end side pressing portion 293h and hooked on the hook portion 293i, so that the harness H is detached from the proximal end side pressing portion 293h. Therefore, it is possible to prevent the harness H from being disconnected by being sandwiched between the cover member 294 and the intermediate member 293, and it is possible to prevent an inadvertent force from being applied to the connection portion, thereby improving work efficiency.

  The cover member 294 is formed in the vicinity of both ends of the groove 293f when attached to the intermediate member 293, and has a pair of through holes 294b that pass through the cover member 294 and through which a binding band (not shown) is inserted. . Further, the cover member 294 is formed between the pair of through holes 294b, and a part of the surface on the harness receiving portion 293c side has a front end side pressing portion 294c protruding to the harness receiving portion 293c side.

  Thus, when assembling the medal selector 201 by forming the harness receiving portion 293c in the intermediate member 293 and forming the groove 293f having the inclined portion 293g in the harness receiving portion 293c, the operator can set the harness receiving portion 293c. In addition, a harness H extending in a predetermined direction is disposed. And as shown in the path | route B, a binding band is arrange | positioned on the back side of the harness H by inserting a binding band in the groove | channel 293f from the surface side of the harness H. Thereafter, the binding band is further pushed into the groove 293f, whereby the tip of the binding band comes into contact with the inclined portion 293g of the groove 293f and protrudes to the surface side of the harness H. In this state, the operator can bundle or fix the harness H by binding both ends of the binding band whose front end protrudes to the surface side of the harness through the back side of the harness H. Thereby, the operation | work which makes a binding band project to the surface side after turning to the back side of a harness becomes easy. Therefore, it is possible to provide a gaming machine that can improve the work efficiency of the assembly work of the device for detecting with high accuracy a fraudulent act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine.

  In addition, when the medal selector 201 is assembled by forming the pair of through holes 294b in the cover member 294 that covers the harness receiving portion 293c and forming the front end side pressing portion 294c therebetween, the operator Arranges the harness H extending in a predetermined direction on the harness receiving portion 293c and covers the harness receiving portion 293c with the cover member 294. Then, the leading end of the binding band is inserted into the inside of the cover member 294 through the one through hole 294 b from the outside of the cover member 294. Then, the binding band is inserted into the groove 293f and disposed on the back side of the harness H. Thereafter, by further pushing the binding band into the groove 293f, the tip of the binding band comes into contact with the inclined portion 293g of the groove 293f, protrudes to the surface side of the harness H, passes through the other through hole 294b, and passes through the outside of the cover member 294. Protrusively. In this state, the operator binds both ends of the binding band to fix the harness H to the cover member 294 in a state where the harness H is pressed against the distal end side pressing portion 294c. Thereby, even after covering the harness H with the cover member 294, the binding band can be easily rotated to the back side of the harness H and fixed to the cover member 294. Therefore, it is possible to provide a gaming machine that can improve the work efficiency of the assembly work of the device for detecting with high accuracy a fraudulent act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine.

  Returning to FIG. 8, the cover member 294 is disposed behind the intermediate member 293, and can be attached and detached with a screw 294 a while covering the camera unit 209 and the wiring board 288 disposed on the intermediate member 293. The member 293 is fixed.

  The select plate 207 is a member that guides a medal moving on the medal rail 210 at a position that is attached to the base plate portion 204 and overlaps the through hole 221a of the sub plate 205.

FIG. 13 is a perspective view of the select plate 207 of the medal selector 201.
As shown in FIG. 13, the select plate 207 is disposed on the rear surface 204 b (see FIG. 8) side of the base plate portion 204, and has a plate body 224 formed in a substantially trapezoidal plate shape. A pair of bearing portions 225 extending to the front side (the front surface 204a (see FIG. 9) side of the base plate portion 204) and having a bearing hole 225a through which a shaft portion 228 (see FIG. 9) described later passes. doing. In addition, a flange portion 226 is formed on the upper portion of the plate body 224 so as to extend to the front side of the pachi-slot 1 (the front surface 204a side of the base plate portion 204) and bend the end portion upward. . In addition, in one bearing portion 225, a medal that extends downward on the front surface 204a side of the base plate portion 204 in a direction different from the plate body 224 across the bearing hole 225a and has a protruding portion 227a formed at the end. A stopper portion 227 is formed. The protruding portion 227a can protrude from the lower exposed hole 220 (see FIG. 8) of the medal rail 210 toward the rear surface 204b of the base plate portion 204.

  As shown in FIG. 8, the plate body 224 extends along the medal rail 210 at a portion where the through hole 221 a of the sub-plate 205 is disposed.

  As shown in FIG. 9, the select plate 207 rotates to the base plate portion 204 when the shaft portion 228 provided on the front surface 204 a of the base plate portion 204 is inserted into the bearing holes 225 a of the pair of bearing portions 225. Supported as possible. The select plate 207 is a direction in which the flange portion 226 rotates about the bearing hole 225a toward the front side of the pachi-slot 1 by a coil spring 229 provided on the shaft portion 228, and the protruding portion 227a (see FIG. 8). The medal rail 210 is biased in a direction protruding from the lower exposed hole 220 (see FIG. 8) toward the rear surface 204b of the base plate portion 204. The flange portion 226 is in contact with one end portion of the medal solenoid 208. When the medal solenoid 208 is in the ON state, the flange portion 226 is pressed by one end of the medal solenoid 208 and moves to the rear of the pachislot 1 against the urging force of the coil spring 229. The rotation position of the select plate 207 at this time is referred to as a “guide position”. When the medal solenoid 208 is in the OFF state, the flange portion 226 is released from the pressing of the medal solenoid 208 and moves forward of the pachislot 1 by the biasing force of the coil spring 229. The rotation position of the select plate 207 at this time is referred to as a “discharge position”.

FIG. 14 is a diagram illustrating a medal path when the medal selector 201 guides the medal to the hopper device.
In the state shown in FIG. 14, the select plate 207 is disposed at the guide position, and the shortest distance from the lower side 224a of the plate body 224 to the lower side 210a of the medal rail 210 is the minimum dimension. This minimum dimension is a dimension slightly smaller than the allowable minimum diameter of the medal standard dimension. Therefore, if the medal passing between the medal rail 210 and the plate main body 224 conforms to the standard size, the end of the medal is caught by the plate main body 224 and guided by the plate main body 224, and the hopper device 51 (FIG. 4). The medals exit part 204c (see FIG. 4) is discharged. At this time, the protrusion 227a (see FIG. 8) of the medal stopper 227 does not protrude from the lower exposure hole 220.

On the other hand, when the medal passing between the medal rail 210 and the plate main body 224 is smaller than the standard size, the end of the medal is not caught by the plate main body 224 and is pressed by the medal pressure 213 (see FIG. 8). Then, it falls in a direction away from the medal rail 210 (Y direction in FIG. 14), falls downward before reaching the medal outlet portion 204c, and the medal payout port 32 (see FIG. 2) through the medal chute 202 (see FIG. 4). Discharged from.
In this embodiment, the select plate 207 is normally positioned at the guide position, but under predetermined conditions (for example, when the maximum number of medals that can be credited (50), when an error occurs, when a game starts, etc.) Then, it can be positioned at the discharge position.

FIG. 15 is a diagram showing a medal path when the medal selector 201 guides the medal to the medal chute.
In the state shown in FIG. 15, the select plate 207 is disposed at the discharge position, the protrusion 227 a of the medal stopper 227 protrudes from the lower exposure hole 220, and extends from the lower side 224 a of the plate body 224 to the lower side 210 a of the medal rail 210. Is the dimension larger than the minimum dimension shown in FIG. This dimension at the discharge position is larger than the maximum allowable diameter of the medal standard dimension. Therefore, the medal passing between the medal rail 210 and the plate main body 224 is not caught by the plate main body 224, so that the medal stopper portion 227 that is pressed by the medal pressure 213 or protrudes from the lower exposure hole 220 is used. Is pushed out by the projecting portion 227a, falls in the direction away from the medal rail 210 (Y direction in FIG. 15), falls downward before reaching the medal outlet portion 204c, and pays the medal through the medal chute 202 (see FIG. 4). It is discharged from the outlet 32 (see FIG. 2).

<Main part structure of camera unit>
FIG. 16 is an exploded view for explaining the positional relationship between the medal rail 210 and the camera unit 209. In FIG. 16, the illustration of the cancel shooter 206 (see FIG. 8) and a wiring board 288 (see FIG. 18) to be described later are omitted for easy understanding.
The camera unit 209 is a unit that determines whether or not the object moving on the medal rail 210 is a regular medal.
The camera unit 209 is disposed at a position facing the medal rail 210 in a portion where the through hole 221 a of the sub plate 205 is disposed, and is fixed by screwing to the cancel shooter 206.

FIG. 17 is an exploded perspective view of the camera unit 209.
The camera unit 209 includes an acrylic resin mounting unit 296, a lens protection cover 295 as lens protection means, a lens unit 287 (imaging lens), a lens holder 275 as lens holding means, and an acrylic resin protection cover sheet 297. And a CMOS image sensor 232 (see FIG. 30) attached to the wiring board 288.

  The acrylic resin mounting unit 296 has an offset portion 293b (see FIG. 11) of the intermediate member 293 of the cancel shooter 206 in a state where the acrylic resin plate 296a as a light transmitting plate formed of a light transmitting material is sandwiched and fixed. It is fixed to. The acrylic resin plate 296a is disposed between the intermediate member 293 (see FIG. 11) and the lens unit 287, and closes the opening 293a (see FIG. 11) of the intermediate member 293.

  The lens protective cover 295 is fixed to the acrylic resin mounting unit 296 and is formed in a shape surrounding the lens unit 287. The lens holder 275 holding the lens unit 287 is connected to the medal rail 210 (see FIG. 16) and the CMOS image sensor 232 ( (See FIG. 30). The lens protection cover 295 is incorporated in such a manner that the end on the medal rail 210 side is in close contact with the acrylic resin plate 296 a and the end on the CMOS image sensor 232 side is in close contact with the wiring board 288.

  Specifically, the lens protective cover 295 has a lens engaging portion 295a that engages with the outer periphery of the lens holder 275 at the end on the CMOS image sensor 232 (see FIG. 30) side. In the example shown in the present embodiment, the lens protection cover 295 has a hollow, substantially quadrangular prism-shaped portion that surrounds the lens unit 287, and a lens engaging portion 295a is formed at the end of the portion on the wiring board 288 side. Has been. The lens engaging portion 295a has an inner wall formed in substantially the same shape as the outer periphery of the lens holder 275 formed in a substantially quadrangular prism shape. In addition, the lens engaging portion 295a is formed with a pair of concave portions 295b in which a part of the outer periphery of the lens holder 275 can protrude from the lens engaging portion 295a. A part of the outer periphery of the lens holder 275 and the pair of recesses 295b of the lens engaging portion 295a are fitted to each other.

  In the present embodiment, a GPIO connector 288a capable of connecting a harness is disposed on the wiring board 288 adjacent to the CMOS image sensor 232 (see FIG. 30). When the lens protective cover 295 is in close contact with the wiring board 288, at least a part of the GPIO connector 288a (for example, four of the five exposed GPIO connectors 288a other than the surface to which the harness is connected). ) Is formed. Further, the connector protection portion 295c is in close contact with the wiring board 288, thereby enclosing a surface other than the surface to which the harness of the GPIO connector 288a is connected. As a result, the surface other than the surface to which the harness of the GPIO connector 288a is connected is protected by the connector protection unit 295c and the wiring board 288.

  The lens unit 287 is provided with lenses 283 to 285 (see FIG. 18), which will be described later, arranged so that the optical axis is directed toward the medal rail 210. The lens holder 275 is fixed to the lens protection cover 295, and holds the lens unit 287 on the CMOS image sensor 232 (see FIG. 30) so that an image can be formed. The protective cover sheet 297 made of acrylic resin is disposed in a direction opposite to the direction in which the lens unit 287 of the lens holder 275 is supported.

  Further, on the wiring board 288 of the camera unit 209, a CMOS image sensor 232 (see FIG. 30), which will be described later, and a control LSI 234 (see FIG. 30) connected to the CMOS image sensor 232 so as to be communicable and controllable. Is provided. The CMOS image sensor 232 (see FIG. 30) images a medal that moves on the medal rail 210 and outputs image data of the imaged medal to the control LSI 234. The specific configuration of the camera unit 209 circuit will be described later.

  In this embodiment, the camera unit is configured by one substrate on which the CMOS image sensor 232 and the control LSI 234 are provided. However, the camera unit 209 is configured by configuring the CMOS image sensor 232 and the control LSI 234 on separate substrates. Also good. Further, a CCD can be used in place of the CMOS image sensor 232 as a solid-state image sensor of the image sensor.

  Thus, the lens holder 275 that holds the lens unit 287 is surrounded by the lens protection cover 295, and the end of the lens protection cover 295 on the medal rail 210 (see FIG. 16) side is brought into close contact with the acrylic resin plate 296a. By incorporating the end of the CMOS image sensor 232 (see FIG. 30) in close contact with the wiring board 288, foreign matters such as cigarette grease and dust are contained in the lens protective cover 295 in which the lens unit 287 is accommodated. Can be prevented from entering. Therefore, it is possible to provide a gaming machine that can prevent foreign matter from adhering to the lens for detecting with high accuracy an illegal act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine.

  Further, at the end of the lens protective cover 295 on the CMOS image sensor 232 (see FIG. 30) side, a lens engaging portion 295a that engages with the outer periphery of the lens holder 275 is partially engaged with the lens. A recess 295b that can protrude from the portion 295a was formed. Accordingly, when the camera unit 209 is assembled, a part of the outer periphery of the lens holder 275 holding the lens unit 287 is fitted into the recess 295b, and the outer periphery of the lens holder 275 is engaged with the lens engaging portion 295a. The lens unit 287 can be arranged and fixed at an appropriate position with respect to the CMOS image sensor 232. Therefore, the assembly operation of the camera unit 209 is facilitated.

  Moreover, since at least a part of the GPIO connector 288a arranged on the wiring board 288 is surrounded by the connector protection unit 295c, foreign matter can be prevented from entering the GPIO connector 288a, so that the foreign matter is inserted into the GPIO connector 288a. However, it is possible to prevent so-called goto, which performs an illegal act. Further, since the connector protection portion 295c surrounding at least a part of the GPIO connector 288a is formed on the lens protection cover 295 surrounding the lens unit 287, the member protecting the lens unit 287 and the member protecting the GPIO connector 288a are integrated. Since it is possible to create a member (lens protective cover 295) having a plurality of functions with a single mold, it is possible to reduce design and manufacturing costs.

The camera unit 209 will be described in detail.
FIG. 18 shows a cross-sectional structure (14A) of the main part of the camera unit 209 and a lens holder 275 (14B) used for the main part of the unit. In the following description using FIG. 18, the top is the direction in which the medal rail 210 (see FIG. 8) is arranged.
On the wiring substrate 288 of the camera unit 209, electronic components such as a CMOS image sensor 232, a control LSI 234, and an LED driving unit 252 shown in FIG. 30 to be described later, and a cover glass 289 are mounted. A lens holder 275 is crowned on the upper side of the wiring board 288. The wiring substrate 288 is configured by a glass epoxy substrate, a ceramic substrate, or the like, and a wiring pattern (not shown) is formed on the surface of the wiring substrate 288.

  As shown in (14B), the lens holder 275 has a lower portion 277 having a rectangular opening 279 that opens downward, and an upper portion 276 that is narrower than the lower portion 277. The upper part 276 is provided with a cylindrical through hole 278 into which the lens unit 287 shown in (14A) is mounted. A female screw portion 281 is formed on the inner surface of the through hole 278. The through-hole 278 is formed with a tapered portion (inclined portion) 282 that is above the upper end edge 280 of the female screw portion 281 and outward. As shown in (14A), the lens holder 275 is fixed on the wiring board 288 with an adhesive 291 so as to cover the cover glass 289. As shown in FIG. 16, the lens holder 275 is supported on an acrylic resin mounting unit 296, and is fixed to a cancel shooter 206 (see FIG. 8) via an acrylic resin protective cover sheet 297 and a lens protective cover 295. . As shown in (14A), the lens holder 275 has a lens holding structure having a lens holding structure for holding a plurality of condenser lenses (lenses 283 to 285) in a multilayered form in front of the CMOS image sensor 232 (see FIG. 30). Means. The lens holding means is not limited to the case using the lens holder 275, and for example, a lens holding structure in which lenses are arranged and held in a multilayered manner via a spacer can be used. The condensing lens is not limited to a convex lens, and a deformed lens having a cross-sectional shape can be used. In addition, the lens unit 287 of this embodiment has the characteristics of a single-focus, substantially wide-angle lens by adopting a lens holding structure that holds a plurality of condenser lenses (lenses 283 to 285) in a multilayer shape. .

  As the main material of the lens holder 275, various resins such as a thermosetting resin such as an epoxy resin or a thermoplastic resin such as a PC resin can be used. In the present embodiment, a liquid crystal polymer composite (LCPC) is used for the lens holder 275. LCPC is one of the synthetic resins (liquid crystal polymer materials) belonging to thermoplastic resins that exhibit liquid crystal-like properties. LCPC has less dust generation and excellent properties such as heat resistance and rigidity compared to resin materials other than liquid crystal polymer materials. The lens unit 287 is also formed of the same material as the lens holder 275.

  If the condenser lenses (lenses 283 to 285) and the lens holder 275 are slightly distorted and deformed due to a temperature change, the distortion (deformation) causes a focus (focus) shift of the captured image, which affects the accuracy of marking determination and color determination. End up. In the present embodiment, the lens holder 275 and the lens unit 287 are manufactured by LCPC, which is a main material, so that the lens thickness, curvature, refractive index, or the height dimension of the lens holder 275 and the distance between the lenses are interposed via a spacer. Even if the spacer thickness or the like in the case of stacking is to be thermally deformed, the original shape is maintained by the characteristics of the LCPC so as to cancel out these deformations, so that a lens holder 275 suitable for stable imaging operation is realized. Can do.

<Composition structure of lens holder and lens unit>
The constituent materials of the lens holder 275 and the lens unit 287 have a composition structure in which LCPC and glass filler (GF) blended at 30% (weight ratio) with respect to LCPC are blended. The blending ratio of GF is not limited to 30% and may be 10 to 40%. As composition materials other than LCPC and GF, carbon black, antioxidant, heat stabilizer, ultraviolet absorber, antistatic agent, flame retardant, etc. for enhancing light shielding properties are slightly mixed in the lens holder 275 and the lens unit 287. ing.

  FIG. 19 shows test results obtained by conducting an environmental test at a temperature higher than normal temperature (50 ° C., 60 ° C., 70 ° C.) on a lens holder 275 molded at various GF blending ratios (six levels of 0 to 50). Indicates. The environmental test results show that the degree of change in lens thickness, curvature and refractive index caused by temperature rise is ○ (small change), △ (change is more remarkable than “○” which does not affect the imaging operation) , X (resulting in a change that affects the imaging operation).

  As can be seen from the environmental test results in FIG. 19, it is preferable to blend GF with 10 to 40% (weight ratio) with respect to LCPC. Although distortion occurs in each lens of the compound lens due to the temperature rise, structural distortion other than lens distortion (for example, distortion caused by pressure when the lens interferes with the lens holder 275 and the lens unit 287) also occurs. In the case of the composition structure with the blending ratio of 10 to 40%, the structural distortion can be deformed so as to cancel out on the holder material side, and canceled and suppressed or suppressed. High-quality imaging can be performed without any problem. In particular, some lens distortion occurs due to temperature rise, but the structural distortion has been eliminated. Therefore, it is only necessary to take measures in the imaging process for lens distortion that can be analyzed in advance, and there is no need to add structural distortion countermeasure parts. The manufacturing cost of the lens holding mechanism (camera unit 209 and lens unit 287) can be reduced without incurring unnecessary cost increase, which contributes to the cost reduction of the gaming machine.

  As shown in (14A), the lens unit 287 has a two-stage cylindrical shape of a large diameter portion and a small diameter portion as a whole, and three condenser lenses (lenses 283 to 285) are mounted inside the cylinder. It is a lens accommodating part of the accommodated compound lens system unit. The large-diameter lens 283 is mounted on the intermediate lens 284 at the large-diameter portion via an antireflection diaphragm component 283a. The upper periphery of the lens 283 is pressed and fixed by a stopper member 283b. A cover sheet 283c is mounted on the upper side of the lens 283. A lens 284 and a lens 285 are provided in the small diameter cylindrical portion of the lens unit 287. The lens 284 and the lens 285 are stacked with a spacer 284a interposed therebetween. The lens 285 is separated into two lenses 285a and 285b via an antireflection diaphragm component 285c. The anti-reflection diaphragm parts 283a and 285c are diaphragm parts for determining the F value of the lens (an index indicating the brightness of the lens). A male screw portion 286 that can be screwed to the female screw portion 281 is formed on the outer periphery of the small diameter portion of the lens unit 287. In a state where the lens holder 275 is fixed on the wiring substrate 288, the through hole 278 faces the cover glass 289.

  As the condensing lenses of the lenses 283 to 285, lenses that generate barrel distortion are used. Image formation by a condensing lens is generally accompanied by distortion that is distorted into a barrel shape or a pincushion shape. When a pincushion type lens is used, a pincushion type distortion aberration occurs, so that the central region without distortion becomes small and it is difficult to acquire a wide range of high-quality images. In this embodiment, by using a lens that generates barrel distortion, a wide range of image acquisition is possible, and distortion correction processing of image data that takes into account distortion aberration of the lens that causes barrel distortion is performed. Is going. The distortion correction process for image data is executed before it is executed in a marking determination process and a color determination process described later.

FIG. 20 shows an image data area obtained through a lens in which barrel distortion occurs.
The image data area shows a barrel-shaped whole area 16a including distortion as a whole, and the central area 16b is an area without distortion. An engraving determination processing means (first determination means) by an image recognition DSP circuit 242 (see FIG. 31) and a color determination processing means (second determination means) by a color recognition circuit 247 (see FIG. 31) described below are distorted. It can be executed based on the corrected image data obtained by correcting the distorted area of the entire area 16a excluding the center area 16b having no distortion into image data without distortion by the distortion correction processing.
The color determination processing means (second determination means) by the color recognition circuit 247 (see FIG. 31), which will be described later, requires less accuracy than the marking determination processing, and therefore the image data of the central area 16b is obtained from the image data of the entire area 16a. Execution is possible based on the excluded image data.

  By the above-described image data distortion correction process, the medal marking determination process and the color determination process can be executed with high accuracy based on the corrected image data without distortion. Moreover, since it is possible to correct and execute image data in a region including distortion captured in a wide-angle range with a lens that generates barrel distortion, it is multi-functionalized by a plurality of determination processes, and the medal determination accuracy is improved as a whole. Improvements can be made.

  As shown in (14A), the lens unit 287 has a male screw portion 286 screwed onto the female screw portion 281 at a position where the uppermost lens 283 is substantially flush with the upper end of the lens holder 275. It is fixed. The lens unit 287 is fixed to the lens holder 275 after adjusting the lens position. This fixing is performed by injecting and solidifying an adhesive 292 into a gap formed between the outer periphery of the small-diameter portion of the positioned lens unit 287 and the tapered portion 282 of the lens holder 275.

<Assembly method of camera unit>
FIG. 21 shows an assembling procedure for assembling the lens holder 275 on the substrate.
This assembling method is executed as a part of the manufacturing method of the gaming machine. First, the position of the lens unit 287 is adjusted in a state in which the lens body before fixation, in which the three lenses 283 to 285 are mounted, is assembled and the lens body is screwed into the through hole 278 of the lens holder 275. (Step S1).

  Next, an adhesive 292 is applied and injected into the gap formed between the outer periphery of the small diameter portion of the lens unit 287 and the tapered portion 282 of the lens holder 275, and the lens body is temporarily fixed (temporary bonding) (step). S2).

  As the adhesive 292, a thermosetting resin adhesive or an ultraviolet (UV) curable resin adhesive can be used. Preferably, for example, an ultraviolet curable resin adhesive such as an ultraviolet curable epoxy resin adhesive is used. The ultraviolet curable resin adhesive has advantages that the curing speed is high, a relatively short working time is required, and that curing is not required unless UV irradiation is performed, so that there are less restrictions on the coating process, and that low temperature curing is possible.

  In the present embodiment, with the lens unit 287 adjusted in position, the lens unit 287 is temporarily bonded using an ultraviolet curable epoxy resin adhesive (step S2). Thereafter, the adhesive is baked by irradiating ultraviolet rays of 280 to 450 nm for several minutes (step S3). In addition, the atmosphere temperature at the time of baking is preferably 80 to 100 ° C. in which the lens holder 275 and the lens unit 287 are not deformed, and the UV irradiation time is preferably 20 to 40 seconds in which the material of the lens holder 275 and the lens unit 287 is not deteriorated. .

  According to the present embodiment, since the tapered portion 282 is formed outward from the upper end edge 280 of the female screw portion 281, it is formed between the outer periphery of the small diameter portion of the lens unit 287 and the tapered portion 282 of the lens holder 275. Thus, the adhesive can be sufficiently permeated into the gap that can be formed, and the adhesive can be sufficiently filled and applied to the lower part of the gap, and the solid production can be reduced by UV irradiation and the assembly and manufacturing cost can be reduced by a simple work process.

  After fixing the lens unit 287 to the lens holder 275, the lens holder 275 is placed on the wiring board 288, and the lens holder 275 and the wiring board 288 are bonded by the adhesive 291 (step S4). Thereafter, other parts are attached, and the camera unit 209 is completed.

  When assembling the lens system of the lens unit 287, by simply bonding the holder part of the lens holder 275 and the lens housing part of the lens unit 287, misalignment at the time of assembly or protrusion of the adhesive to the lens, etc. May occur. Such misalignment or the like causes variations in captured images, but in this embodiment, a lens unit 287 that is a lens housing portion mounted in the through-hole 278 and a taper that is an inclined portion that opens outward on the outer peripheral portion. The lens unit 287 and the lens holder 275 are bonded to each other by injecting an adhesive 292 that is an adhesive means between the region formed by the portion 282. As a result, the lens mounting structure of the camera unit 209 is strengthened, so that there is no misalignment when the CMOS image sensor 232 (see FIG. 30) and the condenser lens are assembled, or the adhesive protrudes into the lens. Therefore, it is possible to perform highly accurate marking and color determination processing based on a high-quality captured image.

  In addition, the UV curable resin adhesive used for the adhesive has a faster curing speed than the thermosetting resin adhesive, and it is polymerized and cured in a short time by UV irradiation. Since it has easy-to-use characteristics, it can be temporarily bonded by application after alignment at the manufacturing stage before fixing the holder part and the lens housing part, and it can be solidified quickly by ultraviolet irradiation. The assembly work time can be shortened, the assembly process can be simplified, and the manufacturing cost can be reduced.

  The camera unit 209 according to the above assembly is mounted with the uppermost lens 283 of the compound lens system facing the passage of the medal rail 210 (see FIG. 16 and the like). The camera unit 209 includes a CMOS image sensor 232 (see FIG. 30) that performs imaging using LED light as a light source, and a compound lens (a condensing lens of lenses 283 to 285) provided in front of the CMOS image sensor 232. As shown in (14A) of FIG. 18, in the camera unit 209, the LED light from the light irradiation mechanism described later can be directly guided to the CMOS image sensor 232 by the condensing lenses 283 to 285. That is, it has an LED light attracting mechanism in which a space without inclusions is provided between the condenser lens and the image sensor.

  As a solid-state imaging device in an image sensor mounted on a mobile phone, a digital camera, or the like, a silicon photodiode having sensitivity to near infrared rays is used in a light receiving portion thereof. For this reason, when using indoor illumination light or natural light as a light source, it is necessary to perform visibility correction, and a glass IR having a thickness of about 1 mm between the condensing lens (the lowermost lens of the compound lens) and the image sensor. A cut filter is installed. However, when an IR cut filter is used, the distance (optical length) from the lower end surface of the lowermost lens 285 to the surface of the image sensor becomes longer, which reduces the installation cost of extra mounting parts for mounting the IR cut filter and IR cut filter. It creates a problem that requires. In particular, thermal deformation distortion is generated at the bonded portion of the IR cut filter to generate a noise component at the interface. Therefore, it is necessary to remove the noise component, and this work is also one of the factors in increasing the manufacturing cost.

  In this embodiment, paying attention to the use of LED light that does not contain an IR component (see FIG. 24) as a light source, the camera unit 209 has a space free of inclusions between the condenser lens and the image sensor. Since the LED light attracting mechanism is provided and the condenser lens is held so as to be able to form an image on the image sensor, the LED light generated in the passage can be directly attracted to the image sensor, and the optical length necessary for the image formation Can be shortened to the shortest distance at least by the thickness of the IR cut filter. In the case of the present embodiment, the height H from the cover sheet 283c to the surface of the wiring board 288 is a minute height of about 11 to 12 mm. By such shortening, the unit structure can be made smaller and more compact, and IR The number of parts of the filter can be reduced, the installation cost is unnecessary, and the cost can be significantly reduced. Furthermore, no noise component is generated at the interface when using the IR filter, and effective use of imaging data in the visible light region This makes it possible to improve the accuracy of medal color and marking determination.

  (18A) in FIG. 22 shows the appearance of the first light guide 261, and (18B) shows the appearance of the second light guide 262. In FIG. 22, the center of the formation location of the reflection grooves 267 and 270 is indicated by a broken line. FIG. 23 shows the external shape of the third light guide 263.

  As shown to (18A), the 1st light guide 261 consists of the linear part 264 and the curved part 265, has a substantially L shape as a whole, and has a rectangular cross section. On the bottom surface of the first light guide 261, the light introduced from the LED 233La (see FIG. 14) from the end portion 265a on the curved portion 265 side is guided to the end portion 266 on the straight portion 264 side so as to emit light uniformly over the entire length. Reflective grooves 267 for efficiently propagating to the light guide are engraved at a plurality of locations so as to cross the longitudinal direction of the light guide. The formation interval of the reflection grooves 267 is gradually shortened toward the end portion 266. When the first light guide 261 is attached to the medal selector 201 (see FIG. 16), the substantially L-shaped outer surface 261a that is the inner side surface of the first light guide 261 faces the medal rail 210. It is used as a surface emitting light source for irradiation.

  As shown in (18B), the second light guide 262 has a linear shape with a rectangular cross section. On the bottom surface of the second light guide 262, the light introduced from the LED 233Lb (see FIG. 14) from one end 268 is efficiently propagated to the other end 269 so as to emit light uniformly over the entire length. Reflective grooves 270 are formed at a plurality of locations so as to be transverse to the longitudinal direction of the light guide. The formation interval of the reflection grooves 270 is gradually shortened toward the end portion 269. When the second light guide 262 is attached to the intermediate member 293 (see FIG. 8) of the cancel shooter 206, a rectangular outer surface which is an inner side faced obliquely downward of the second light guide 262 262 a is used as a surface emitting light source that irradiates the medal rail 210.

  As shown in FIG. 23, the third light guide 263 includes a flat portion 263a having a substantially right triangle shape and a light guide portion 263b having a substantially triangular pyramid shape. The end surface 263h of the light guide 263b indicated by oblique lines has an unequal triangular shape. The three-dimensional side surface of the light guide portion 263b includes a triangular side surface 263c on the long side of the unequal side triangle of the end surface 263h, a triangular side surface 263d on the short side, a tip triangular surface 263e with the tip portion cut obliquely, and a flat portion 263a. The edge 263i is formed between the triangular side surface 263d and the tip triangular surface 263e along the edge 263j of the flat portion 263a along the edge 263j formed between the triangular side surface 263c and the tip triangular surface 263e. It is comprised by the skirt side surface 263g. When the third light guide 263 is attached to the intermediate member 293 (see FIG. 8) of the cancel shooter 206, the triangular side surface 263c of the third light guide 263 serves as the medal rail 210 as the first light guide surface. It is used as a surface emitting light source that irradiates toward the surface. The triangular side surface 263d is used as a light source for halation that irradiates surface light on the opposite side to the triangular side surface 263c as a second light guide surface.

The bottom surface of the flat portion 263a has a plurality of reflection grooves 271 for efficiently transmitting the light introduced from the end surface 263h in the light guide portion 263b so that the light is uniformly emitted over the entire side surface of the light guide portion 263b. Are engraved parallel to the bottom surface. Each reflection groove 270 is formed at substantially equal intervals.
The 1st light guide 261, the 2nd light guide 262, and the 3rd light guide 263 are modeled with acrylic resin which can inject introduction light from the side. In addition to the acrylic resin, a light-transmitting material capable of emitting side light, for example, Teflon (registered trademark) or an optical fiber material can be used as the modeling material.

(20B), (20A), and (20C) in FIG. 24 are for attaching the first light guide 261, the second light guide 262, and the third light guide 263 to the medal selector 201, respectively. It is a figure explaining attachment members 272, 273, and 274.
As shown in (20B), the first light guide 261 is housed in a substantially L-shaped interior groove provided in the mounting member 272 so that the outer surface 261a is exposed. By fixing the mounting member 272 to the sub-plate 205 (see FIG. 16) with screws, the first light guide 261 has an outer surface 261a exposed from the mounting member 272 as shown by a two-dot chain line in FIG. Are arranged in the direction of the medal rail 210, and the surface emitting light emitted from the outer surface 261 a can be irradiated obliquely and above the medal passing through the medal rail 210.

  As shown in (20A), the second light guide 262 is inserted and held in the mounting member 273 so that the outer surface 262a is exposed in the front direction. As shown in FIG. 16, the mounting member 273 is fixed to the inner side of the intermediate member 293 (see FIG. 8) of the cancel shooter 206 with a screw via an acrylic resin mounting plate 298, whereby the second light guide body 262 is secured. As shown by a two-dot chain line in FIG. 14, the outer surface 262a exposed from the mounting member 273 is arranged in a slanting manner downward toward the curved portion 265 along the medal passage direction, and from the outer surface 262a. The emitted light of the surface emission can be irradiated to the medal passing through the medal rail 210 from below.

  The flat portion so that the light guide portion 263b is exposed by engaging the step portion on the back side of the flat portion 263a of the third light guide 263 shown in FIG. 23 in the longitudinal direction of the mounting member 274 shown in (20C). As shown by a two-dot chain line in FIG. 14, the rear surface of 263a is brought into contact with the mounting member 274, and the mounting member 274 is fixed to the inner side of the intermediate member 293 (see FIG. 8) of the cancel shooter 206 with screws. The emitted light from the light guide part 263b of the third light guide 263 can be irradiated to the front of the medal passing through the medal rail 210.

  As shown in FIG. 14, the medal rail 210 is composed of an upstream region extending in the vertical direction from the medal inlet portion 211 and a downstream region gently inclined from the end of the upstream region toward the medal outlet portion 204c. An imaging region RLa (see FIG. 25) by the camera unit 209 is provided in the inclined passage in the downstream region. The three first to third light guides configured as described above are disposed so as to surround the imaging region RLa with a substantially elliptical ring shape.

FIG. 25 shows an arrangement relationship of the first light guide 261, the second light guide 262, and the third light guide 263.
The first light guide 261 is disposed on the front side (medal entry side) of the inclined passage of the medal rail 210 and on the upper side of the upper end edge of the passage. An imaging region RLa capable of receiving light in the camera unit 209 (see FIG. 16) is provided from the vicinity of the curved portion 265 of the first light guide 261 to the lower side of the linear portion 264 and above the lower end edge of the passage. The second light guide 262 is arranged at a position where the inclined passage can be irradiated from below the passage lower end edge of the medal rail 210. The third light guide 263 is arranged on the end side of the passage of the medal rail 210 so that the edge 263 i extends along the transverse direction of the passage on the rear side from the end 266 of the first light guide 261.

  The first light guide body 261, the second light guide body 262, and the third light guide body 263 are disposed so as to surround the inclined passage of the medal rail 210 in a substantially oval shape. Due to surface light emission from the outer surface 261a of the light body 261, the outer surface 262a of the second light guide 262, and the triangular side surface 263c of the third light guide 263, at least the central region RLb of the imaging region RLa has uniform illuminance. It is an area. A medal marking determination unit RLc is provided from the end of the imaging region RLa to the end of the passage. The third light guide 263 is disposed on the back side of the cancel shooter 206, and can irradiate light for halation in the imaging region. That is, the region from the end of the imaging region RLa to the end of the passage, with the marking determination unit RLc substantially at the center, is a halation region RLd that can receive surface light emission from the triangular side surface 263d of the third light guide 263. The marking determination based on the image data is performed at the timing when the passing medal reaches the marking determination unit RLc. In the halation region RLd, the medal passage determination process can be performed with high accuracy using the halation caused by the light irradiated on the passage surface.

  In the LED light irradiation mechanism of the light guide, LED light can be uniformly irradiated so as to surround the imaging region in a ring shape such as a substantially oval shape, so the edge and contour of the game medium, patterns such as engravings, colors, etc. It is possible to realize a gaming machine that can reliably capture the image and perform high-precision determination processing based on accurate imaging data. Since uniform LED light can be irradiated like a ring, accurate imaging data can be obtained from the subject (passing game medium) without causing reflection of the light source due to reflection of the passing game medium, that is, no halation of primary reflection. It is possible to perform highly accurate determination processing, in particular, determination processing of game media marking and contour.

  Since the LED light from the second light guide surface (triangular side surface 263d) is irradiated to the passage surface other than the imaging region to cause halation, the shade of reflection at the irradiation position becomes clear, and the passage of the game medium is determined. Can be used. In other words, since halation occurs on the discharge passage surface to the hopper side, the difference in the amount of reflected light between when there is a medal passing and when there is no medal is clarified. Can be determined with high accuracy. Further, since halation does not occur even when medals are paid out or when medals cannot be inserted, it is possible to determine whether or not the medal has been returned to the lower plate by confirming that there is no occurrence.

  Since the LED light for the imaging region and the LED light for the passage surface other than the imaging region can be emitted from the two side faces (triangular side surfaces 263c and 263d) of the triangular pyramid of the second light guide, a single light guide is provided. The two types of LED light irradiation mechanisms can be configured compactly and inexpensively by the body. Since the irradiation mechanism that can uniformly irradiate LED light like a ring such as a substantially rectangular shape can be divided into three parts by the first to third light guides 261 to 263, each light guide is arranged around the passage. It can be distributed in a narrow space and can be made compact and inexpensive. In addition, in this Embodiment, although the structure which has arrange | positioned LED233La-233Lc to the 1st-3rd light guides 261-263, respectively was demonstrated, it is not restricted to this, The brightness | luminance insufficient of the medal rail 210, and the light to irradiate May not be uniform, a plurality of (for example, two) LEDs may be disposed in each of the first to third light guides 261 to 263.

  FIG. 26 shows an emission wavelength characteristic graph of the LEDs 233La to 233Lc used in the present embodiment. In the figure, the vertical axis represents relative emission intensity, and the horizontal axis represents wavelength. As can be seen from this graph, the LEDs 233La to 233Lc emit infrared light having a wavelength range of 440 nm to 460 nm based on the blue color having a steep emission intensity peak near the wavelength of 450 nm. It has a light emission wavelength characteristic that does not include a light emission component (IR component) in the Infrared Radiation) region and a light emission component (UR component) in the UR (Ultraviolet Radiation) region that is ultraviolet radiation.

<Main control circuit>
Next, the main control circuit 91 constituted by the main control board 71 will be described with reference to FIG.
FIG. 28 is a block diagram illustrating a configuration example of the main control circuit 91 of the pachi-slot 1.

  The main control circuit 91 includes a microcomputer 92 installed on the main control board 71 as a main component. The microcomputer 92 includes a main CPU 93, a main ROM 94, and a main RAM 95. The main CPU 93 and the hopper device 51 described above constitute a game medium payout device of the present invention. The main control circuit 91 functions as an example of a control unit that performs control related to a game.

  The main ROM 94 is used to transmit various control commands (commands) to the control program executed by the main CPU 93 (for example, the program for executing the internal lottery process described above), the data table, and the sub-control circuit 101. Data etc. are stored. The main RAM 95 is provided with a storage area for storing various data such as an internal winning combination determined by execution of the control program.

  The main CPU 93 is connected to a clock pulse generation circuit 96, a frequency divider 97, a random number generator 98, and a sampling circuit 99. The clock pulse generation circuit 96 and the frequency divider 97 generate clock pulses. The main CPU 93 executes a control program based on the generated clock pulse. The random number generator 98 generates a random number in a predetermined range (for example, 0 to 65535). The sampling circuit 99 extracts one value from the generated random numbers.

The main CPU 93 counts the number of times pulses are output to the stepping motors of the reels 3L, 3C, 3R after detecting the reel index. Thereby, the main CPU 93 manages the rotation angle of each reel 3L, 3C, 3R (mainly, how many symbols the reel has rotated).
The reel index is information indicating that the reel has made one revolution. This reel index is provided at a predetermined position of each of the reels 3L, 3C, 3R, for example, with a light emitting unit and a light receiving unit, and between the light emitting unit and the light receiving unit by the rotation of each reel 3L, 3C, 3R. Detection is performed by a reel position detection unit (not shown) including a detection piece interposed therebetween.

  Here, the management of the rotation angle of each reel 3L, 3C, 3R will be specifically described. The number of pulses output to the stepping motor is counted by a pulse counter provided in the main RAM 95. Each time the output of a predetermined number of pulses (for example, 16 times) necessary for the rotation of one symbol is counted by the pulse counter, the symbol counter provided in the main RAM 95 is incremented by one. The symbol counter is provided for each reel 3L, 3C, 3R. The value of the symbol counter is cleared when a reel index is detected by a reel position detector (not shown).

  In other words, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each reel 3L, 3C, 3R is detected with reference to the position where the reel index is detected.

  As described above, when the maximum number of sliding symbols is set to four symbols, the symbol of the left reel 3L in the middle of the reel display window 4 when the left stop button 19L is pressed, and the four symbols. Each symbol within the range up to the previous symbol becomes a symbol that can be stopped at the middle stage of the reel display window 4.

For example, the control program includes a main board communication task for controlling communication with the main control circuit 91 and an effect registration task for extracting and registering effect contents (effect data) by extracting effect random numbers. Is included. In addition, a drawing control task for controlling display of an image by the liquid crystal display device 11 based on the determined content of the presentation, a lamp control task for controlling light output from a light source such as the LED 85, and speakers such as speakers 58, 64, 65L, and 65R. This includes a voice control task for controlling the output of sound.

  The data storage area includes a storage area for storing various data tables, a storage area for storing effect data constituting each effect content, and a storage area for storing animation data related to creation of video. Also included are a storage area for storing sound data related to BGM and sound effects, a storage area for storing lamp data related to the light on / off pattern, and the like.

<Circuit configuration of medal selector>
Next, the circuit configuration of the medal selector 201 will be described with reference to FIG.
FIG. 30 is a block diagram illustrating a circuit configuration example of the medal selector 201. The medal selector 201 includes a camera unit 209 and a medal solenoid 208. The medal selector 201 is connected to the main control board 71 via the door relay terminal board 68. That is, the medal selector 201 is electrically connected to the main control circuit 91 so as to be capable of mutual communication. Therefore, the main control circuit 91 can set the medal solenoid 208 of the medal selector 201 to the ON state or the OFF state.

  The camera unit 209 includes a control LSI 234, a CMOS image sensor 232, and an LED drive unit 252. The control LSI 234 of the camera unit 209 is configured by an ASIC (Application Specific Integrated Circuit) and is electrically connected to the CMOS image sensor 232 and the LED group 233. The LED group 233 includes three LEDs 233La to 233Lc (see FIG. 16). The control LSI 234 controls the light emission of the LED group 233 via the LED drive unit 252. Further, the control LSI 234 determines whether the insertion is a regular medal based on the image data output from the CMOS image sensor 232, and outputs the determination result to the main control board 71 via the door relay terminal board 68. . In the present embodiment, the adopted CMOS image sensor 232 is a CMOS image sensor having a resolution of 648 × 488 pixels and a frame rate of 240 fps (Frames PerSecond).

<Circuit configuration of control LSI>
Next, the circuit configuration of the control LSI 234 will be described with reference to FIGS. 31 and 32. FIG.
FIG. 31 is a block diagram illustrating a circuit configuration example of the control LSI 234. FIG. 32 is a diagram for explaining a regular medal, in which A represents one side of the regular medal, B represents image data of the regular medal, and C represents gradient average image data to be described later related to the regular medal. is there.

  The control LSI 234 includes a host controller 241 incorporating a CPU, an image recognition DSP (digital signal processor) circuit 242, an SRAM (Static Random Access Memory) 243, a flash memory 244, an ISP (Image Signal Processing) circuit 245, and a medal count circuit 246. The control LSI 234 includes a color recognition circuit 247, a fisheye correction scaler circuit 248, an image recognition accelerator circuit 249, and a GPIO (General Purpose Input / Output) 250. The devices constituting the control LSI 234 are connected to each other via a bus, and the control LSI 234 according to the present embodiment employs AXI (Advanced eXtensible Interface) as a bus protocol.

  The control LSI 234 includes an ISI (Image Sensor Interface) circuit 251. The ISI circuit 251 is electrically connected to the CMOS image sensor 232 and the ISP circuit. The ISI circuit 251 converts the image data output from the CMOS image sensor 232 by the LVDS (Low voltage differential signaling) method into an RGB Bayer image, and outputs it to the ISP circuit 245.

When receiving the RGB Bayer image from the ISI circuit 251, the ISP circuit 245 outputs a VSYNC (Vertical Synchronization) interrupt signal to the host controller 241.
The ISP circuit 245 performs a conversion process for converting the RGB Bayer image output from the ISI circuit 251 into various formats. In the conversion process, the ISP circuit 245 converts the RGB Bayer image into Y (the luminance of each pixel), and stores the converted image data in the SRAM 243. Further, the ISP circuit 245 converts the RGB Bayer image into image data (YUV image data) corresponding to the YUV color space, and outputs data relating to the luminance (Y) in this YUV image data to the medal count circuit 246. Further, the ISP circuit 245 converts the RGB Bayer image into image data (HSV image data) corresponding to the HSV color space, and performs color recognition on the data relating to the hue (H) and the saturation (S) in the HSV image data. Output to the circuit 247.

  The medal count circuit 246 performs count processing based on the data relating to the luminance output from the ISP circuit 245. In the count process, the medal count circuit 246 compares the data relating to the brightness of the count area, which is a predetermined area in the image, with the count threshold value, and determines whether or not a medal has passed by the background difference method. The count threshold is a threshold determined in advance based on data relating to the brightness of the count area in the image of the regular medal. The medal count circuit 246 determines that the medal has passed if the difference is small, and determines that the medal has not passed (other than the medal has passed) if the difference is large. Then, the medal count circuit 246 stores the determination result in the SRAM 243.

  The count area can be arbitrarily set according to the medal used as the regular medal by the pachislot 1. However, the count area is preferably set to an area where the rotation angle of the medal does not greatly affect the luminance difference. For example, when using regular medals with the same marking (pattern) on both sides shown in FIG. 32A, the image data of the regular medals (see FIG. 32B) is applied to one side of the regular medals in the area. The place (area surrounded by a dotted line in FIG. 32B) is set as the count area so that the stamp (pattern) does not change with the rotation angle of the medal, that is, the rotation angle of the medal does not greatly affect the difference in luminance. Is preferred. In addition, the narrower the count area, the faster the counting process.

  The color recognition circuit 247 performs color determination processing based on data relating to hue and saturation output from the ISP circuit 245. In the color determination process, the color recognition circuit 247 first expresses an integrated value of data related to hue and saturation near the center of the image data as a vector (vector conversion), and calculates the angle of the vector in a three-dimensional space. To do. Next, the color recognition circuit 247 compares the calculated vector angle with a predetermined color threshold value, and determines whether or not the color matches the color of the regular medal. The predetermined threshold is a predetermined threshold based on the vector angle calculated by the same method as the above-described processing for the image data related to the regular medal (for example, in the three-dimensional space related to the regular medal to be compared). Within ± 10 degrees of the angle on the individual coordinates (XYZ) of the vector. The color recognition circuit 247 stores the determination result in the SRAM 243.

  The fish-eye correction scaler circuit 248 acquires image data obtained by Y-converting the RGB Bayer image from the SRAM 243 and performs fish-eye correction processing. In the fisheye correction process, the fisheye correction scaler circuit 248 corrects the acquired image data with fisheye to create reduced image data reduced to 1/2, 1/4, and 1/8. Then, the fisheye correction scaler circuit 248 stores the created reduced image data in the SRAM 243.

  The image recognition DSP circuit 242 acquires reduced image data (in this embodiment, reduced image data reduced to ¼) from the SRAM 243 and performs preprocessing. In the preprocessing, the image recognition DSP circuit 242 converts the acquired reduced image data into edge image data through a non-linear diffusion filter, and stores the edge image data in the SRAM 243.

  The image recognition accelerator circuit 249 performs a rotation integration process for creating gradient average image data. In the rotation integration process, the image recognition accelerator circuit 249 acquires edge image data from the SRAM 243, and integrates (superimposes) 360 degree image data created by rotating the acquired edge image data in units of one degree. ) Create gradient average image data. As an example of the gradient average image data, the gradient average image data of the regular medal shown in FIG. 32A is shown in FIG. 32C.

  Further, the image recognition DSP circuit 242 performs a stamp determination process for determining whether or not the stamp (pattern) of the medal matches the stamp of the regular medal. In the marking determination process, the image recognition DSP circuit 242 acquires from the SRAM 243 gradient average image data created by the image recognition accelerator circuit 249 through the rotation integration process. Next, the image recognition DSP circuit 242 calculates the difference between the acquired gradient average image data and the template data for the marking determination process (prepared average medal gradient average image data). Then, the image recognition DSP circuit 242 determines whether the medal stamp matches the stamp of the regular medal based on the calculated difference value and the threshold for determining the stamp, and stores the determination result in the SRAM 243. For example, the image recognition DSP circuit 242 compares the luminance of each pixel of the acquired gradient average image data and the template data, and determines whether or not they match (in the case of multi-tone, whether the difference is within a predetermined range). If there are more than a certain number of matching pixels (difference is within a predetermined range), it is determined that the medal stamp (pattern) matches the stamp of the regular medal. If the number of matching pixels is less than the predetermined number, the medal stamp is determined. It is determined that (pattern) does not match the stamp of the regular medal.

The host controller 241 controls each device, that is, the medal count circuit 246, the color recognition circuit 247, the fisheye correction scaler circuit 248, the image recognition DSP circuit 242, the image recognition accelerator circuit 249, and the GPIO 250.
In addition, the host controller 241 outputs a signal related to a lighting instruction or a lighting instruction to the LED group 233 via the GPIO 250. Further, the host controller 241 outputs, via the GPIO 250, the determination result related to the count process, the determination result related to the color determination process, and the determination result related to the marking determination process stored in the SRAM 243.

  The flash memory 244 stores parameters and data (including the template data described above) used by the host controller 241, the image recognition DSP circuit 242, the fisheye correction scaler circuit 248, and the image recognition accelerator circuit 249 for various processes.

  Next, referring to FIG. 33, a process for determining whether or not the object moving on the medal rail 210 (see FIG. 14) is a regular medal performed by the control LSI 234 (hereinafter referred to as “regular medal discrimination process”). Will be described).

  FIG. 33 is a diagram for explaining the regular medal discrimination process of the control LSI 234. FIG. 33 shows the relationship of processing in each device constituting the control LSI 234 in time series. The relatively thick line portion extending below each device name indicates the various processing described above for the device. It shows that it is in the state of going. A broken line arrow extending from a line corresponding to each device toward a line extending below “IN” in the host controller indicates an interrupt signal output from each device to the host controller 241. A broken line arrow extending from a line extending below “OUT” in the host controller toward a line corresponding to each device indicates a signal output from the host controller 241 to each device. In addition, a solid arrow between a line extending below “IN” and a line extending below “OUT” in the host controller is output from the interrupt signal detected by the host controller 241 and the host controller 241. The corresponding relationship with the signal is shown. FIG. 33 shows a regular medal discrimination process when six medals are continuously inserted into the medal insertion slot 21. In addition, in order to clarify the number of medals related to the signal, a number indicating the number of medals is attached to the head of the code attached to each signal. For example, a VSYNC interrupt signal output to the host controller 241 from an ISP circuit 245, which will be described later, related to the first medal is labeled with “1IH”, and the same VSYNC interrupt related to the second medal is assigned. The signal was labeled “2IH”.

  First, when the CMOS image sensor 232 images an object (in this example, the first medal) moving on the medal rail 210 (see FIG. 14) and outputs the image data to the control LSI 234, the ISP circuit 245 includes the ISI circuit. Image data is acquired (received) via 251 and a VSYNC (Vertical Synchronization) interrupt signal is output to the host controller 241 (1IH). Further, the ISP circuit 245 performs conversion processing for converting the RGB Bayer image into various formats. Then, the converted image data and the hue, saturation, and luminance data relating to the image data are output to the SRAM 243, the medal count circuit 246, and the color recognition circuit 247. The detailed description of the conversion process has been described above, and will not be repeated.

  When receiving data from the ISP circuit 245, the color recognition circuit 247 performs color determination processing, stores the determination result in the SRAM 243, and outputs a color determination interrupt signal to the host controller 241 (1CH). Note that the detailed description of the color determination process has been described above, and will be omitted.

  When the medal count circuit 246 receives data from the ISP circuit 245, the medal count circuit 246 performs count processing, stores the determination result in the SRAM 243, and outputs a medal count interrupt signal to the host controller 241 (1MH). Note that the detailed description of the count process has been described above, and is therefore omitted.

  When the host controller 241 detects the color determination interrupt signal, the host controller 241 acquires the determination result of the color determination processing from the SRAM 243 and outputs it to the allocation PORT of the GPIO 250 (1HG1). That is, the host controller 241 outputs the determination result of the color determination process to the main control board 71 (main control circuit 91) via the GPIO 250.

  When the host controller 241 detects the count interrupt signal, the host controller 241 acquires the determination result of the count process from the SRAM 243 and outputs it to the allocation PORT of the GPIO 250 (1HG2). That is, the host controller 241 outputs the determination result of the count process to the main control board 71 (main control circuit 91) via the GPIO 250. When the determination result of the counting process is “medal has passed”, the main control circuit 91 sets the value of the inserted number counter, which is a counter provided for the main CPU 93 to count the number of inserted medals. Add one. When the value of the inserted number counter is the maximum value (for example, 3), 1 is added to the value of a credit counter that is a counter provided for the main CPU 93 to count the number of credited medals. When the credit counter is the maximum value (for example, 50), the main control circuit 91 sets the medal solenoid 208 of the medal selector 201 to the OFF state. As a result, as shown in FIG. 15, the select plate 207 is positioned at the “discharge position”, and medals inserted after the credit counter reaches the maximum value are guided to the medal chute 202 (see FIG. 4) and medals. It is discharged from the payout opening 32 (see FIG. 2) to the medal tray unit 34 (see FIG. 2). In the present embodiment, when the value of the insertion number counter is a specified value (for example, 2 or 3), when the start lever is operated, the main CPU 93 performs the above-described internal lottery process.

  Returning to FIG. 33, when the image data converted by the ISP circuit 245 is stored in the SRAM 243, the fish-eye correction scaler circuit 248 performs fish-eye correction processing, stores the created reduced image data in the SRAM 243, A reduction end interrupt signal is transmitted to the controller 241 (1SH). Since the detailed description of the fisheye correction process has been described above, it will be omitted.

  Between the output of the determination result of the count process by the host controller 241 to the GPIO 250 (1HG2) and the transmission of the reduction end interrupt signal by the fisheye correction scaler circuit 248 (1SH), the second circuit by the ISP circuit 245 An output (2IH) of a VSYNC interrupt signal related to a medal is generated. However, since the storage areas of the SRAM 243 are individually set for storing the determination results of various processes (counting process, color determination process, engraving determination process, etc.) related to each medal, no data overwriting occurs.

  When the host controller 241 detects the reduction end signal, the host controller 241 refers to the SRAM 243, and the determination result of the count process is “the medal has passed”, and the determination result of the color determination process is “matches the color of the regular medal” The image recognition DSP circuit 242 performs preprocessing according to an instruction from the host controller 241, stores the edge image data in the SRAM 243, and the host controller 241 performs preprocessing. An end interrupt signal is output (1DH1). Note that the detailed description of the pre-processing has been described above and is omitted.

  When the host controller 241 detects the preprocessing completion interrupt signal, it instructs the image recognition accelerator circuit 249 to start the rotation integration process (1HA).

  The image recognition accelerator circuit 249 performs rotation integration processing in accordance with an instruction from the host controller 241, stores the gradient average image data in the SRAM 243, and outputs an integration end interrupt signal to the image recognition DSP circuit 242 (1AD). Since the detailed description of the rotation integration process has been described above, the description thereof will be omitted.

  When detecting the integration end interrupt signal, the image recognition DSP circuit 242 acquires gradient average image data stored in the SRAM 243, performs a marking determination process, and stores the determination result in the SRAM 243. Then, the image recognition DSP circuit 242 outputs a marking determination end interrupt signal to the host controller 241 (1DH2).

  When the host controller 241 detects the marking determination end interrupt signal, the host controller 241 acquires the determination result of the marking determination process stored in the SRAM 243 and outputs it to the GPIO allocation PORT (1HG3). That is, the host controller 241 outputs the determination result of the marking determination process to the main control board 71 (main control circuit 91) via the GPIO 250.

As shown in FIG. 33, in the present embodiment, the pre-processing and marking determination processing by the image recognition DSP circuit 242 and the rotation integration processing by the image recognition accelerator circuit 249 take a relatively long time. Therefore, when medals are continuously inserted, the host controller 241 detects whether the image recognition DSP circuit 242 or the image recognition accelerator circuit 249 is processing (busy state) when detecting the reduction end signal, When none of them are being processed, an instruction is given to start preprocessing and marking determination processing by the image recognition DSP circuit 242 and rotation accumulation processing by the image recognition accelerator circuit 249. Therefore, in this embodiment, when the host controller 241 detects the reduction end signals (2SH and 3SH) related to the second and third medals, the image recognition DSP circuit 242 or the image recognition accelerator circuit 249 is processing ( The host controller 241 does not give the start instruction. Therefore, for the second and third medals, the count process and the color determination process are performed, but the marking determination process is not performed. On the other hand, when the host controller 241 detects the reduced signal (4SH) related to the fourth medal, the image recognition DSP circuit 242 and the image recognition accelerator circuit 249 are not in processing (busy state). Accordingly, for the fourth medal, a count process, a color determination process, and a stamp determination process are performed.
In addition, by speeding up the pre-processing and marking determination processing by the image recognition DSP circuit 242 and the rotation integration processing by the image recognition accelerator circuit 249, the count processing, color determination processing, and marking determination processing are performed for all inserted medals. It may be performed.

  Various signals related to the second, third, fourth, fifth, and sixth medals shown in FIG. 33 (the code starts with “2”, “3”, “4”, “5”, The “6” signals) are the same as the various signals related to the first medal described above (only the first symbol is “1”), which is different only in the first digit, and detailed description thereof is omitted.

<Action>
In the pachi-slot 1 of the present embodiment, the control LSI 234 of the medal selector 201 performs a regular medal discrimination process including a color determination process, a count process, and a marking determination process. When an unauthorized device that is not a medal moves on the medal rail 210, it is determined that the color does not match the color of the regular medal in the color determination process, and it is determined that the medal has not passed in the count process. Therefore, it is possible to detect an illegal act of playing a game by misrecognizing that a regular medal is used in the pachislot 1.

FIG. 34 is a diagram showing an example of an illegal medal, where A shows one side of the illegal medal and B shows image data of the illegal medal. FIG. 35 is a diagram showing another example of an illegal medal. A shows one side of the illegal medal, B shows image data of the illegal medal, and C shows gradient average image data of the illegal medal. FIG.
When an illegal medal moves on the medal rail 210 with the same diameter and the same color as the regular medal (see FIG. 32A) and only in the stamp (pattern) on the surface of the medal, It is determined that the color matches. However, in the counting process, the imprinted medal image data count area (area surrounded by a dotted line) shown in FIG. 34B and the regular medal image data count area (enclosed by a dotted line in FIG. 32B). Since the engraving (pattern) in the region) is markedly different, it is determined that “the medal has not passed”. Therefore, it is possible to detect an illegal act of playing a game by misrecognizing that a regular medal is used in the pachislot 1.

  In addition, when another illegal medal moves on the medal rail 210 with the same diameter and the same color as the regular medal (see FIG. 32A) and only with a stamp (pattern) on the surface of the medal, It is determined that it matches the color of the regular medal. In the counting process, the imprinted medal image data count area (area surrounded by a dotted line) shown in FIG. 35B and the regular medal image data count area (enclosed by a dotted line in FIG. 32B). It is determined that “the medal has passed” because the difference from the marking (pattern) in the area) is small. However, in the engraving determination process, the gradient average image data of the illegal medal shown in FIG. 34C and the gradient average image data of the regular medal (see FIG. 32C) are significantly different. Does not match ". Therefore, it is possible to detect an illegal act of playing a game by misrecognizing that a regular medal is used in the pachislot 1.

  In addition, when a medal of the same color as the regular medal (see FIG. 32A) and a different diameter (slightly smaller or larger than the diameter of the regular medal and guideable by the select plate 207) and the same color move on the medal rail 210 In the color determination process, it is determined that “matches the color of the regular medal”. However, in the image data of this medal, if this medal is slightly smaller than the diameter of the regular medal and the count area has a boundary between the outer edge of the medal and the background, the “no medal has passed” in the counting process. It is determined. Even if it is determined that the medal has passed in the counting process, the medal gradient average image data and the regular medal gradient average image data (see FIG. 32C) from the difference in diameter between the medal and the regular medal. Will be very different. Therefore, in the marking determination process, it is determined that “the medal stamp (pattern) does not match the stamp of the regular medal”. Therefore, it is possible to detect an illegal act of playing a game by misrecognizing that a regular medal is used in the pachislot 1.

  In addition, when a medal having the same diameter as the regular medal (see FIG. 32A) on the medal rail 210 but having a different color moves, it is determined that the color does not match the color of the regular medal in the color determination process. Therefore, it is possible to detect an illegal act of playing a game by misrecognizing that a regular medal is used in the pachislot 1.

  Further, the control LSI 234 outputs the determination results of the color determination process, the count process, and the marking determination process to the main control circuit 91 including the main control board 71 via GPIO. Therefore, it is possible to cause the main control circuit 91 to perform various processes when there is an illegal act. Here, the various processes when there is a fraudulent action are, for example, that the main control circuit 91 forcibly interrupts the game and notifies the fact that the fraudulent act has occurred via the sub-control circuit 101 (for example, , Displaying that the fraud has occurred on the liquid crystal display device 11).

  Further, when an illegal act is detected based on the determination result of the color determination process and the count process, the main control circuit 91 may set the medal solenoid 208 of the medal selector 201 to the OFF state. As a result, the select plate 207 is positioned at the “discharge position”, so that the illegal medal can be guided to the medal chute 202 and discharged from the medal payout opening 32. The main control circuit 91 sets the medal solenoid 208, which has been set to the OFF state by detecting the cheating by the color determination process and the counting process, to the ON state after guiding the cheating medal related to the cheating to the medal chute 202. May be.

Further, even when an illegal act is detected by the stamp determination process, the main control circuit 91 may set the medal solenoid 208 of the medal selector 201 to the OFF state. In this embodiment, as shown in FIG. 33, the VSYNC interrupt signal (4IH) related to the fourth medal is output from the ISP circuit 245 to the main control circuit 91, and the VSYNC interrupt related to the fifth medal is output. Until the signal (5IH) is output, the determination result of the marking determination process related to the first medal is output to the main control circuit (1HG3). Therefore, when illegal medals are continuously inserted, the illegal medals inserted after the fifth one can be guided to the medal chute 202 and discharged from the medal payout opening 32. As a result, the spread of damage caused by fraud can be suppressed. If the imprint taken by the camera unit 209 passes through the after medal pressure 218 or the medal stopper 227 by speeding up the engraving determination process, an improper act can be detected by the engraving determination process. Since the main control circuit 91 immediately sets the medal solenoid 208 to the OFF state, it is possible to prevent the occurrence of damage due to fraud.
In addition, the main control circuit 91 determines that the medal solenoid 208 that has been set to the OFF state by detecting an illegal act by the stamp determination process indicates that the determination result of the next stamp determination process indicates that the medal stamp (pattern) matches the stamp of the regular medal. If “Yes”, it may be set to ON. As a result, since illegal medals were accidentally mixed, if the player inserts illegal medals without intending fraud, and the medal solenoid 208 is set to the OFF state and the game becomes impossible, the player If a medal is inserted, the game can be resumed.

<Offset correction processing>
Inside the CMOS image sensor 232, a temperature sensor 232a is provided. The temperature sensor 232a is composed of a PN junction (diode) formed on the silicon substrate of the image sensor. The PN junction has a temperature coefficient of about 2 mV / ° C., and when a predetermined constant current flows, a terminal voltage change of the PN junction follows the substrate temperature. The temperature change of the image sensor can be monitored from the detection output of the terminal voltage change by the temperature sensor 232a.

The detection output of the temperature sensor 232a is given to the control LSI 234. The control LSI 234 determines whether or not the temperature in the CMOS image sensor 232 exceeds the threshold temperature based on the detection output of the temperature sensor 232a. When the temperature exceeds the threshold temperature, the control LSI 234 executes offset processing of the reference black level.
The dark current of the CMOS image sensor rises rapidly as the temperature rises, and the black level fluctuates. When the reference black level is shifted, there is a problem that the color reproducibility is deteriorated and the image quality is deteriorated. In the present embodiment, in order to solve such a problem, the following blackout process can be performed to appropriately maintain the reference black level.

FIG. 36 shows an offset process executed by the control LSI 234. FIG. 37 is a temperature change diagram of the offset value showing details of the offset processing.
The offset processing can be executed at a predetermined interrupt timing by the above-described host controller 241 of the control LSI 234. When the detection output of the temperature sensor 232a is received, it is determined whether or not the threshold temperature is exceeded based on the temperature data of the detection output (steps S10 and S11). The threshold temperature data is stored and set in advance in a flash memory 244 described later of the control LSI 234. The threshold temperature can be set in a temperature range above room temperature, and is set to 45 ° C. in this embodiment.

  When the temperature data indicates that the threshold temperature is exceeded, the offset value is corrected by the reference black level for the image data received from the CMOS image sensor 232 (step S12). The initial value of the offset value is set in the flash memory 244 at a low temperature (for example, room temperature 25 ° C.) measured in the manufacturing stage of the image sensor. The offset correction is performed by correcting the linear interpolation value to the reference black level with respect to the offset value of the received image data. The offset value of the CMOS image sensor 232 is set to a value at room temperature in advance in the manufacturing stage for each of the odd pixel column 33a and the even pixel column 33b. When the temperature state of the temperature sensor 232a exceeds the threshold temperature, the linear interpolation value is corrected based on the temperature gradient 33c obtained in advance by experiments. The coefficient value of the temperature gradient 33c used in this embodiment is 1.11. For example, as can be seen from the correction line 33d after 45 ° C. in the odd-numbered pixel row 33a, the offset value gradually increases when it exceeds 45 ° C. For example, at about 54 ° C., the difference 33e from the initial value is 1.55. The corrected offset value is updated and stored in the flash memory 244. The image data based on the updated offset value is used for various signal processing in the control LSI 234. As described above, by using a gaming machine equipped with an image sensor, the above-described offset correction processing is executed at any time according to the operating status, and can be updated.

  When an imaging means (for example, a camera using a CMOS sensor) is mounted on a gaming machine, the camera is always placed in an environment exposed to a high temperature for a long time. Further, when the door of the gaming machine is opened and closed during maintenance such as replenishment of medals, a situation occurs in which the camera ambient temperature fluctuates greatly. On the other hand, since the dark current of the CMOS sensor rapidly increases as the temperature rises, the reference black level of the captured image is shifted to cause a problem of color reproducibility deterioration and image quality deterioration. In the present embodiment, in view of such a problem, the temperature sensor 232a detects and monitors the threshold temperature of the image sensor, and the offset correction unit (step S12) performs offset correction of the image sensor when the threshold temperature is exceeded. Therefore, even if the ambient temperature changes suddenly, the reference black level can be appropriately maintained and high-quality image data can be acquired, and the determination processing can be performed with high accuracy regardless of the ambient temperature fluctuation. . In particular, by performing offset correction to the reference black level with a linear interpolation value, stable passing object image data can be obtained constantly without being affected by temperature changes, so that the marking and color determination processing can be improved. Can be done with precision.

  The LED group 233 includes three LEDs 233La to 233Lc (see FIG. 39), emits light around the CMOS image sensor 232, and irradiates the medals moving on the medal rail 210 with light.

<Circuit configuration of LED driving unit>
The circuit configuration of the LED driving unit 252 will be described with reference to FIGS. 38 and 39. FIG.
FIG. 38 is a block diagram showing the overall configuration of the LED drive unit 252, and FIG. 39 shows a specific circuit configuration of the LED drive unit 252.

  The LED drive unit 252 includes an LED power supply unit 253 with an overcurrent prevention function, a power supply setting unit ON / OFF control unit 254, and an LED constant current drive circuit 255.

  The LED power supply unit 253 with an overcurrent prevention function (hereinafter referred to as the power supply unit 253) can supply current from a power supply 256 having a power supply voltage DC12V. The power supply unit 253 includes a capacitor C1, transistors T1 and T2, and a transistor T3. The base and collector of the transistor T6 are bias-connected and the bases are connected in common to form a current mirror circuit. The transistor T3 is provided on the output stage side of the current mirror circuit. The current mirror circuit constitutes a constant current circuit capable of outputting a constant current (40 mA) through the transistor T3 on the output stage side. One end of the capacitor C1 is connected to the power supply 256 via the resistor R1, and the other end is grounded. The capacitor C1 and the resistor R1 constitute a low pass filter for removing unnecessary high frequency components. Each emitter side of the transistors T1 and T2 is connected to one end side of a capacitor C1 via resistors R1 and R2. The collector sides of the transistors T1 and T2 are grounded via resistors R4 and R5. The base of the transistor T3 is commonly connected to the bases of the transistors T1 and T2. The collector side of the transistor T3 is branched and connected to a ground side grounded through a resistor R5 and a current supply system on the anode side of the LEDs 233La to 233Lc. The power supply 256 can be supplied from the power supply board 53b shown in FIG. When a current is output through the transistor T3 in the output stage, the power supply unit 253 has a current that does not flow beyond a constant current of 40 mA based on the charging voltage of the capacitor C1 and the current mirror circuit (transistors T1 and T2). A limiting circuit is configured. The capacitor C1 has a storage capacity that is charged when a predetermined constant current (for example, 180 mA) flows for a specified time (for example, 250 μs), so that the predetermined constant current has flowed beyond the specified time. In this case, the current mirror circuit (transistors T1 and T2) is used to protect the transistors T7 to T9 by reducing the output current to the rated current.

  The power setting unit ON / OFF control unit 254 includes an ON / OFF control unit 254a and a power setting unit 254b. The ON / OFF control unit 254a and the power supply setting unit 254b are provided on the anode side of the LEDs 233La to Lc.

  The ON / OFF control unit 254a includes a transistor T4 whose base is connected to the constant current source 260 via a resistor R9, and a transistor T5 whose base is connected to the collector side of the transistor T4 via resistors R7 and R8. . The constant current source 260 is a current switch that can be switched between current supply and stop by an LED_EN 258 that is an on / off signal corresponding to the exposure timing from the CMOS image sensor 232 (that is, a VSYNC interrupt signal that is an imaging timing). The emitter and base of the transistor T5 are short-circuited via a resistor R8. The emitter side of the transistor T5 is connected to the anode side of the LEDs 233La to 233Lc. A 5V power source 257 is added between the emitter of the transistor T5 and the anodes of the LEDs 233La to 233Lc. The power supply 257 can be supplied from the power supply board 53b shown in FIG.

  The power supply setting unit 254b includes a transistor T6 whose collector is connected to the anode side of the LEDs 233La to 233Lc via the transistor T5. The collector of the transistor T5 and the collector of the transistor T6 are connected via a parallel circuit of resistors R10 and R11. The parallel circuit branches to the collector side of the transistor T6 and the ground side via the resistor R12. The emitter side of the transistor T6 is branched and grounded through resistors R13 and R14.

  The LED constant current drive circuit 255 includes transistors T7 to T9 provided in the LEDs 233La to 233Lc. The collector of the transistor T7 is connected to the cathode of the LED 233La via a resistor R18. The collector of the transistor T8 is connected to the cathode of the LED 233Lb via the resistor R19. The collector of the transistor T9 is connected to the cathode of the LED 233Lc via the resistor R20. The emitters of the transistors T7 to T9 are connected to the ground line of the resistor R13 via resistors R18 to R20. The bases of the transistors T7 to T9 are commonly connected to the transistor T6 and connected in parallel to each other. The base and collector of the transistor T6 are bias-connected to form a current mirror circuit with each of the transistors T7 to T9. The thermal coupling 259 according to the present invention includes a bias connection element and a base common connection element in each current mirror circuit. The anode sides of the LEDs 233La to 233Lc are grounded via a capacitor C2. The capacitor C2 is discharged (for example, 180 mA) when the LED driving current is supplied (LED_EN 268 is on), and can be charged when the supply is stopped (LED_EN 268 is off). The capacitor C2 is a capacitor having a storage capacity that cannot discharge the surge current for 250 μs or longer. Therefore, even if the ON state of LED_EN 268 continues for 250 μs or longer, a current of 180 mA or higher, which is a predetermined constant current, does not flow to the anode side of LEDs 233La to 233Lc due to the storage capacity of capacitor C2.

In the LED driving unit 252 having the above-described configuration, the following LED on / off operations can be performed.
First, in the power supply unit 253, a constant current of 40 mA is generated by a current mirror circuit constituted by the transistors T1 and T2, and can be supplied to the anode side of the LEDs 233La to 233Lc via the transistor T3. When an ON signal is input from the LED_EN 258 corresponding to the imaging timing from the CMOS image sensor 232 and a current is supplied from the constant current source 260, the transistor T4 provided on the front stage side of the ON / OFF control unit 254a becomes conductive. (Hereinafter, the conductive state is simply referred to as “on state”). When the transistor T4 is turned on, a current flows through the base of the transistor T5, and the transistor T5 is turned on. When the transistor T5 is turned on, a current flows to the collector side of the transistor T6 and the transistor T6 is turned on. Since the transistors T7 to T9 are connected to the current mirror circuit with respect to the transistor T6, the transistors T7 to T9 are simultaneously turned on when the transistor T6 is turned on. When the transistors T7 to T9 are turned on, each LED can be energized with the constant current supply path from the power supply unit 253, and LED light emission is performed by discharging the LED drive current charged in the capacitor C2.

FIG. 40 is a timing chart showing changes in various operations in each part of the LED drive unit 252. The horizontal axis of the figure is the time change, the vertical axis of (36A) shows the change of the exposure time, the vertical axis of (36B) to (36E) shows the change of the voltage value, and the vertical axis of (36E) is the vertical axis. The change in current value is shown.
(36A) and (36B) of FIG. 40 show the exposure time of the CMOS image sensor 232 and the imaging timing of the exposure time, respectively. The pulse (36B) indicates the on time (250 μs). This pulse is output from the CMOS image sensor 232 with a wave height of 3.3 V and a period of 4 ms (VSYNC interrupt signal). The on-time may be 1 m or less, preferably 80 to 250 μs.

  (36C) shows the drive voltage VDD potential of the LED drive unit, and (36D) and (36E) show the collector potential and emitter potential of the LED drive transistors (transistors T7 to T9), respectively. (36F) shows the pulse waveform of the LED drive current. The LED drive current has a rated current value of 40 mA and a rated maximum current value of 180 mA when it is always lit (normal).

When the pulse is turned on, as shown in (36C), the DVV potential of the LED causes a voltage drop 36a due to the current limiting circuit of the power supply unit 253, so that the current limiting function by the power supply unit 253 overloads the LED. Can be prevented. The collector potential of the LED driving transistor drops with a difference of the LED Vf potential with respect to the DVV potential, and returns to the potential determined by the leakage current of the LED and the LED driving transistor as the voltage drop 36a disappears. Since the emitter potential rises slightly during the pulse-on, there is a margin in the potential difference between the collector potential and the emitter potential even if the ground potential (GND potential) fluctuates due to fluctuations and variations in Vf of LED components. By providing, it is possible to absorb the fluctuation of the GND potential.
In the present embodiment, since the imaging possible time (on time: 250 μs) of the imaging cycle is at least 1 msec or less, a current is instantaneously supplied to the LED group 233, and the rated current value is 40 mA when constantly lit (normal). Since the LED group 233 is driven by supplying 180 mA, which is a current value of a higher surge current level, the LED is made to have a high luminance by flowing a driving current larger than that at the time of constant lighting (the luminance of the LED is approximately equal to the current value). It is possible to obtain a high-quality image data by irradiating LED light with high brightness, and to realize a gaming machine capable of performing various determination processes related to medals with high accuracy. The capacitor C2 provided on the anode side of the LED is charged when the LED driving current is supplied, and can be discharged when the supply is stopped.

  Since the transistors T7 to T9 of the LED constant current drive circuit 255 are current mirror connected to the transistor T6 of the power supply setting unit 254b, each LED can be driven to emit light by supplying a mirror current (LED drive current). it can. The transistor T6 on the reference current source side and the transistors T7 to T9 on the LED drive current supply side are thermally coupled to each other by mirror connection, thereby causing a difference in the temperature coefficient between the transistor T6 and each of the transistors T7 to T9. The output current (mirror current) from the transistors T7 to T9 can be supplied to each LED unbalanced with the reference current source side, and the temperature characteristic of the output current from the LED constant current drive circuit 255 is positive. .

As a general characteristic of the LED element, the forward voltage Vf varies depending on the applied current and the temperature, and in particular has a negative temperature characteristic with respect to the temperature rise. In addition, there is a variation in individual characteristics among LED parts. In particular, due to the negative temperature characteristics, the LED emission intensity decreases with increasing temperature, that is, the LED emission luminance decreases at high temperatures. In this embodiment, since the temperature characteristic of the output current is positive, it is possible to cancel the decrease in emission intensity based on the negative temperature characteristic of the LED element. In the case of the present embodiment, the luminance stabilizing means is configured by current mirror connection between the transistor T6 and each of the transistors T7 to T9, so that the change width of the emission intensity in the temperature range of 0 to 100 ° C. is within 1%. . Luminance stabilization means using current mirror connection can be configured easily and inexpensively. For example, there is no need for a temperature sensor for each circuit for program control and a circuit for current control. Cost reduction and reduction of parts count are unnecessary. Unnecessary bugs caused by not installing a simple program can be eliminated, which can contribute to the high functionality and low price of the gaming machine.
In the above specific circuit configuration, a bipolar transistor is used as an active element, but a MOS transistor which is a small signal active element may be used.

  The gaming machine according to one embodiment of the present invention has been described above including the effects thereof. However, the gaming machine of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention described in the claims.

  For example, in the above description, an example was described in which medals having the same marking (pattern) on both sides were used as game media, but instead of this, different markings were made on one side and the other side of the medal. You may use the given medal. In this case, data relating to each face of the medal may be prepared in advance as data relating to the threshold value in the count process, the color determination process, and the marking determination process.

  In addition, as a data setting method related to the threshold value, a certain unit game period (for example, 100 games) is set as a data collection period related to the threshold value, and a medal image captured by the camera unit 209 during the unit game period. A method of setting based on data may be adopted.

[Modification of one embodiment of the present invention]
<Configuration of medal selector according to modification>
Next, a medal selector 301 according to a modification of the embodiment of the present invention will be described.
The pachi-slot 1 according to the present embodiment may include a medal selector 301 according to a modification instead of the medal selector 201 (see FIG. 8). Hereinafter, although the medal selector 301 according to the modification will be described, the same configuration as the medal selector 201 is denoted by the same reference numeral, and the description thereof is omitted or simplified.

The medal selector 301 is mainly different from the medal selector 201 shown in FIG. 8 in the configuration of the base plate portion and the sub plate.
FIG. 41 is an exploded perspective view of the base plate portion 304 and the sub plate 305 of the medal selector 301.
FIG. 42 is a perspective view of the base plate portion 304 of the medal selector 301 as viewed obliquely from the front of the pachi-slot 1.
The medal selector 301 is an example of a game medium detection unit that detects the insertion of a game medium. The medal selector 301 includes a base plate portion 304 and a sub plate 305 and a select plate 207 that are arranged to overlap the base plate portion 304 shown in FIG. 8 includes a cancel shooter 206 and a camera unit 209 shown in FIG. 8, and a medal selection solenoid 308a and a medal reception solenoid 308b shown in FIG.

  Similarly to the medal selector 201, the medal selector 301 has a first light guide body 261, a second light guide body 262, a third light guide body 263, an LED 233La, and a light irradiation mechanism. LED233Lb and LED233Lc are provided. These light irradiation mechanisms function as an example of an irradiation unit that emits light for imaging by the imaging unit.

  As shown in FIG. 41, the base plate portion 304 is a substantially plate-like member that constitutes a part of the outer frame housing of the medal selector 301, and both end portions in the left-right direction of the pachislot 1 are folded back to the pachislot 1. Molded to bend. The base plate portion 304 has a rear surface 304b that is one plane orthogonal to the front-rear direction of the pachislot 1 and a front surface 304a (see FIG. 42) that is the other plane. On the rear surface 304b, a medal rail 210, which is an example of a path through which medals pass, is formed in a substantially L shape so as to be recessed forward from the pachislot 1 and from the upper side to the lower side. A plurality of protrusions are formed on the surface of the medal rail 210 along the direction in which the medal rail 210 extends. Such a base board part 304 functions as an example of a game medium passage part through which a game medium passes. Further, the base plate part 304 on which the medal rail 210 is formed functions as an example of a game medium passage part in which a path through which game media pass is formed.

  At the upper end portion of the base plate portion 304, a medal entrance portion 211 is provided which is connected to the upper end of the medal rail 210 and receives medals inserted from the medal insertion slot 21 (see FIG. 2). A medal inserted into the medal selector 301 from the medal entrance 211 moves along the medal rail 210 from above to below. At the lower part of the base plate part 304, a medal outlet part 304c connected to the lower end of the medal rail 210 is provided. The medals that have moved through the medal selector 301 are discharged from the medal outlet 304c and accommodated in the hopper device 51 (see FIG. 5) via the slope 203 (see FIG. 6).

  A medal sorting center hole 212a and a medal receiving center hole 212b are formed on the downstream side of the medal rail 210 at a substantially intermediate position. In the medal sorting center hole 212a, the tip of the medal sorting medal pressure 213a can be exposed from the front surface 304a (see FIG. 42) side into the medal rail 210 formed on the rear surface 304b. In the medal reception center hole 212b, the tip of the medal reception medal pressure 213b can be exposed from the front surface 304a side into the medal rail 210 formed on the rear surface 304b. The base plate portion 304 is formed with a sub-plate moving hole 212c penetrating in the front-rear direction at a position overlapping the sub-plate 305. In the sub-plate moving hole 212c, the tip end portion of the sub-plate pressure 213c can protrude from the front surface 304a (see FIG. 42) side to the rear surface 304b side.

  As shown in FIG. 42, the medal selection medal pressure 213a is formed in a substantially U-shape, and is supported at a middle portion thereof by a shaft portion 214a provided on the front surface 304a of the base plate portion 304 so as to be rotatable. The base end portion is rotatably connected to the medal sorting solenoid 308a. Thereby, when the medal selection solenoid 308a is in the OFF state, the medal pressure 213a for medal selection is in a state where the base end portion is pushed into the shaft portion 214a side and the front end portion is retracted from the medal rail 210 toward the front surface 304a side. It becomes. When the medal sorting solenoid 308a is turned on, the medal sorting medal pressure 213a rotates with the shaft portion 214a as a fulcrum by pulling the base end portion away from the shaft portion 214a, and the tip portion is a medal. The medals are selected by excluding the medals passing through the medal rail 210 from the medal rail 210 in a state of projecting into the rail 210. The electrical configuration of the medal sorting solenoid 308a will be described later. Such a medal sorting medal pressure 213a functions as an example of a movable moving means for sorting which is movable by driving a medal sorting solenoid 308a which is an example of a game medium sorting means. Further, the medal pressure medal pressure 213a is supported at the intermediate portion by the back surface of the game medium passing portion so as to be rotatable, and the base end portion of the movable moving means for sorting is connected to the game medium sorting device. It serves as an example.

  The medal reception medal pressure 213b is formed of a plate-like body, is rotatably supported by a shaft portion 214b provided on the front surface 304a of the base plate portion 304, and a base end portion is connected to the medal reception solenoid 308b. ing. A coil spring 215b is attached to the shaft portion 214b, and the medal reception medal pressure 213b is biased by the coil spring 215b so as to protrude into the medal rail 210 (rear surface 204b side). ing. Thereby, when the medal acceptance solenoid 308b is in the OFF state, the medal acceptance medal pressure 213b is urged by the coil spring 215b and the tip portion protrudes into the medal rail 210 and passes through the medal rail 210. The medal is excluded from the medal rail 210. Then, when the medal reception solenoid 308b is turned on, the medal reception medal pressure 213b resists the biasing force of the coil spring 215b by pushing the base end portion toward the rear surface 204b where the medal rail 210 is formed. The shaft portion 214b is rotated around the fulcrum, and the tip portion is retracted from the medal rail 210 toward the front surface 304a. The electrical configuration of the medal reception solenoid 308b will be described later. Further, the front end of the medal acceptance medal pressure 213b is arranged on the medal rail 210 upstream of the front end of the medal selection medal pressure 213a with respect to the passing direction of the medal. The medal reception solenoid 308b for driving such a medal reception medal pressure 213b is upstream of the position in which the game medium selection means selects the game medium with respect to the passing direction in which the game medium passes through the game medium passing portion. It functions as an example of a game medium receiving unit that excludes game media. Further, the medal reception medal pressure 213b functions as an example of a movable reception means that moves by driving a medal reception solenoid 308b, which is an example of a game medium reception unit.

  Further, the base plate portion 304 is rotated when the return button 21a (see FIG. 2) is operated by the player, and a sub plate pressure 213c for rotating the sub plate 305 to the rear surface 204b side is rotatable. Is provided. The intermediate portion of the sub-plate pressure 213c is rotatably supported by a shaft portion 214c provided on the front surface 304a of the base plate portion 304, and the base end portion is directly or indirectly attached to the return button 21a (see FIG. 2). Connected. Thereby, when the return button 21a is operated by the player, the sub-plate pressure 213c moves the base end portion downward, rotates the shaft portion 214c as a fulcrum, the tip end portion moves upward, and the tip end portion Protrudes from the sub-plate moving hole 212c (see FIG. 41), and rotates the sub-plate 305 toward the rear surface 204b.

  Returning to FIG. 41, the medal rail 210 is formed with a plurality of determination holes 312 (five places in the present embodiment) penetrating in the front-rear direction in the imaging region RLa (see FIG. 25) by the camera unit 209. Yes. The determination hole 312 is imaged by the camera unit 209 together with the medal passing through the medal rail 210, so that the distinction between the medal and the medal rail 210 becomes clear in the image used for the medal determination process. The determination of medals is facilitated, and the accuracy of the medal determination process is improved.

  The plurality of determination holes 312 are arranged along the direction in which the medal rail 210 extends, and the width in the direction in which the medal rail 210 extends is closer to the upstream side of the medal rail 210 (the medal inlet 211 side). (For example, the width of the determination hole 312 on the upstream side is about 20 mm, the width of the determination hole 312 on the downstream side is about 5 mm, and the width of the determination hole 312 in the middle region is about 10 mm). The plurality of determination holes 312 are a plurality of holes provided on the upstream side and the downstream side of the game medium passing portion, and the direction in which the game medium passes through the hole on the downstream side of the hole on the upstream side. In contrast, it functions as an example of a plurality of short holes. As a result, even on the upstream side of the medal rail 210 where the passing speed of the medal is relatively fast, it is possible to reliably image the medal together with the determination hole 312 and improve the accuracy of the medal determination process. Further, since the determination hole 312 on the downstream side of the medal rail 210 with a relatively slow medal passing speed is formed with a relatively short width in the direction in which the medal rail 210 extends, space saving can be achieved. It can be provided together with the medal sorting center hole 212a and the medal receiving center hole 212b.

  The plurality of determination holes 312 are not limited to such an aspect, and may be formed in the same width or the same shape. Further, the determination hole 312 is formed in a substantially rectangular shape along the direction in which the medal rail 210 extends (the direction in which the medal flows down), but is not limited thereto, and is formed in an arbitrary shape such as a circular shape or a triangular shape. May be.

  A shielding member 312a (shaded portion in FIG. 41) is affixed to the front surface 304a side of the determination hole 312 (on the non-imaging surface side of the camera unit 209 (see FIG. 8) as an example of the imaging means).

  The shielding member 312a shields the front surface 304a side and the rear surface 304b side in the determination hole 312 formed in the medal rail 210, and displays an image captured by the camera unit 209 (see FIG. 8) from the rear surface 304b side on the front surface. The device arranged on the side of 304a is prevented from being reflected. The shielding member 312 a is provided according to the plurality of determination holes 312. The shielding member 312a reflects light from the first light guide 261, the second light guide 262, and the third light guide 263 shown in FIG. The shielding member 312a is made of, for example, a reflective sheet, but may be made of, for example, a mirror-finished metal plate or the like as long as it is a material that reflects light. The reason why the shielding member 312a is made of a material that reflects light such as a reflection sheet is that the medal rail 210 is processed with low light reflectance so as not to hinder the photographing of the camera unit 209. When the non-reflective material is used for the shielding member 312a, the determination hole 312 becomes assimilated with the medal rail 210 and cannot be recognized.

  The camera unit 209 (see FIG. 8) discriminates the plurality of determination holes 312 from an image obtained by imaging light reflected by the shielding member 312a provided according to the plurality of determination holes 312.

  It should be noted that the determination hole 312 may be a concave shape instead of a through-hole as long as it is recessed from the surface (rear surface 304b) of the medal rail 210 where the medal slides, and in this case, in the bottom of the concave shape. A shielding member 312a may be provided.

  The rear surface 304b of the base plate portion 304 is slightly thicker (approximately 1.8 mm to 2.0 mm) than the medal thickness (approximately 1.5 mm) so as to overlap with a part of the sub plate 305 that is an example of the auxiliary member. A protective member 304d is provided.

  The protection member 304 d has an upper side edge disposed along the lower side edge of the medal rail 210 on the rear surface 304 b of the base plate part 304. Thereby, the medal passing the medal rail 210 rolls on the upper side edge of the protection member 304d. The vicinity of the upper side edge of the protective member 304d overlaps with the vicinity of the lower side edge of the sub plate 305. The protective member 304d is made of a glossy metal plate, but is not limited to this, and the first light guide 261, the second light guide 262, and the third light guide shown in FIG. Any material that reflects light from H.263 may be formed of a reflective sheet or the like.

Next, the configuration of the sub plate 305 will be described.
The sub-plate 305 is a plate-like member provided at a position overlapping the medal rail 210 of the base plate portion 304, the upper end side is rotatably attached to the base plate portion 304, and the lower end side is a protection for the base plate portion 304. By abutting against the member 304d, a space (about 1.8 mm to 2.0 mm) through which a medal rolling on the protection member 304d passes is formed between the medal rail 210 and the medal rail 210. The sub-plate 305 has a flat plate-shaped main body part 321, a shaft part 222 provided on the upper part of the main body part 321, and an attachment member 272 (see FIG. 8) for attaching the first light guide 261. doing. A substantially central portion of the main body 221 is disposed behind the position including the medal sorting center hole 212a, the medal receiving center hole 212b, and the plurality of determination holes 312 of the medal rail 210, and penetrates in the front-rear direction. 221a is provided, and the downstream region is exposed from the substantially central portion of the medal rail 210 from the through hole 221a. The through hole 221a is included in a predetermined area including the medal rail 210 that is imaged by the camera unit 209 (see FIG. 16).

  Further, the main body 321 is formed to be connected to the lower side edge of the through hole 221a, and is formed at the rear end of the main body 321 (downstream end of the medal rail 210). The first guiding part 321a for guiding the medal outlet 304c to the outside of the medal selector 301, and the second guiding part for guiding the medal repelled downward from the medal rail 210 by the medal selection medal pressure 213a or the medal reception medal pressure 213b. 321b and a plurality of sub-plate state detection holes 321c formed in a predetermined area imaged by the camera unit 209 (see FIG. 16) in the vicinity of the through hole 221a.

  The first guide portion 321a has a downstream side edge of the medal rail 210 of the base plate portion 304 (a side edge provided with the medal outlet portion 304c) in a state where the sub plate 305 is in contact with the protective member 304d of the base plate portion 304. ) Along the side frame 305c.

FIG. 43 is a perspective view of the sub plate 305 of the medal selector 301 as viewed obliquely from the front of the pachi-slot 1.
The first guiding portion 321a extends along the medal outlet portion 304c (see FIG. 44 described later) in a state where the sub plate 305 is in contact with the protective member 304d (see FIG. 41) of the base plate portion 304. The first guiding portion 321a is a rear surface 305b that does not face the base plate portion 304 of the sub-plate 305 from the upstream (medal inlet portion 211) side to the downstream (medal outlet portion 304c) side of the medal rail 210 (see FIG. 41). From FIG. 41, it has the inclined surface which inclines toward the front surface 305a which faces the base board part 304 of the subplate 305. As shown in FIG. As a result, for example, the medal shoots without being caught on the side frame 305c of the sub-plate 305 by the medal repelling medal pressure 213a or the medal reception medal pressure 213b immediately before being discharged from the medal outlet 304c. By guiding to 202, it is possible to prevent the medal from passing through to the medal outlet 304c side. Further, in a space through which medals pass, a medal outlet portion 304c from which medals are discharged and an inclined surface that is inclined toward the slope 203 that is connected upstream to the medal outlet portion 204c and connected downstream to the hopper device 51 are provided. Thus, it is possible to prevent medals from staying in the vicinity of the medal outlet portion 304c or the entrance of the slope 203 and clogging the medal outlet portion 304c or the slope 203.

  Returning to FIG. 41, the second guide portion 321b is below the lower edge (the phantom line L shown in FIG. 41) of the medal rail 210 in a state where the sub plate 305 is in contact with the protective member 304d of the base plate portion 304. The medal rail 210 extends in the extending direction. The second guiding portion 321b has an inclined surface that is inclined downward from the medal rail 210 side in a direction away from the medal rail 210.

  Here, a medal payout port 32 (see FIG. 2) is provided below the medal selector 301, and a medal chute 202 (see FIG. 4) connected to a medal tray unit 34 (see FIG. 2) as an example of a staying means. ) Is provided. The medals discharged from the medal outlet 304c are accommodated in a hopper device 51 (see FIG. 5), which is an example of a storage unit, via a slope 203 (see FIG. 6).

  The medals repelled from the medal rail 210 by the medal selection medal pressure 213a or the medal reception medal pressure 213b fall from the medal rail 210 without reaching the medal outlet 304c, and fall on the inclined surface of the second guiding portion 321b. It is guided and falls to the medal tray unit 34 through the medal chute 202. In this way, the second guiding portion 321b functions as a second guiding portion for guiding the game medium toward the staying means.

  In addition, the medals repelled by the medal selection medal pressure 213a or the medal reception medal pressure 213b just before reaching the medal exit portion 304c are also guided to the inclined surface of the first guide portion 321a and are then removed from the medal rail 210. It falls, is guided to the inclined surface of the second guiding portion 321b, passes through the medal chute 202, and falls onto the medal tray unit 34. Thus, the first guiding portion 321a functions as a first guiding portion for guiding the game medium in a direction different from the direction leading to the storage means when the game medium is not guided to the storage means.

  The sub plate state detection holes 321c are rectangular holes penetrating the main body 321 in the front-rear direction, and a plurality of sub plate state detection holes 321c are arranged along the lower side edge of the through hole 221a in the vicinity of the through hole 221a. The sub-plate state detection hole 321c is disposed at a position overlapping the protection member 304d when the sub-plate 305 is in contact with the protection member 304d of the base plate portion 304. Therefore, in a state where the sub plate 305 is in contact with the protective member 304d of the base plate portion 304, the light from the second light guide 262 shown in FIG. 14 is inserted through the sub plate state detection hole 321c for protection. Reflected by the member 304d. The sub-plate state detection hole 321c is formed in a rectangular shape, but is not limited thereto, and may be formed in an arbitrary shape such as a circular shape or a triangular shape.

Next, the operation of the sub plate 305 will be described.
44 and 45 are diagrams for explaining the operation of the sub-plate 305. FIG. FIG. 44 shows a state in which the sub plate 305 is in contact with the protective member 304 d of the base plate portion 304. FIG. 45 shows a state in which the sub plate 305 is rotated and the sub plate 305 and the protective member 304d of the base plate portion 304 are separated from each other. 44 and 45 is a line schematically showing light from the second light guide 262. In FIG.

  As shown in FIG. 44, when the sub plate 305 is in contact with the protection member 304d of the base plate portion 304 (normal state), the light from the second light guide 262 is transmitted to the sub plate state detection hole 321c. The light is reflected by the protective member 304d.

On the other hand, when the player operates the return button 21a (see FIG. 2), the tip of the sub plate pressure 213c (see FIG. 41) protrudes from the sub plate moving hole 212c (see FIG. 41), and the sub plate 305 Rotates to a state shown in FIG.
In the state shown in FIG. 45 (the state in which the return button 21a is operated), the sub-plate state detection hole 321c is inclined with respect to the surface (reflection surface) of the protective member 304d, and the second light guide 262 Is reflected by the protection member 304d without passing through the sub-plate state detection hole 321c. That is, the light from the second light guide 262 is reflected differently from the case where the sub plate 305 is not rotated.

  Therefore, when the sub plate 305 shown in FIG. 44 is in contact with the protective member 304d of the base plate portion 304 (normal state), the light from the second light guide 262 passes through the sub plate state detection hole 321c. Since the light is reflected, in the image captured by the camera unit 209 (see FIG. 16), the sub-plate state detection hole 321c has a higher brightness than the surrounding main body 321.

  On the other hand, in the state in which the return button 21a shown in FIG. 45 is operated, the sub plate 305 is separated from the protective member 304d of the base plate portion 304, and the light from the second light guide 262 is transmitted to the sub plate state detection hole 321c. Therefore, in the image captured by the camera unit 209 (see FIG. 16), the sub-plate state detection hole 321c is in the normal state. In comparison, the brightness is lowered.

  Thereby, the accuracy of determination of whether or not the camera unit 209 is in a state in which the sub plate 305 is in contact with the protective member 304d of the base plate portion 304 is improved by these images. For example, if it is determined that there is a medal passing through the medal rail 210 even though it is determined that the sub plate 305 is separated from the protective member 304d of the base plate portion 304, an illegal act is performed. It can be estimated that there is a high possibility.

  In order to realize such determination by the camera unit 209, in a modification, the lower end of the imaging region RLa (see FIG. 25) that can receive light in the camera unit 209 is lower than the lower end edge of the medal rail 210 shown in the embodiment. The base plate 304 is extended to a range including a plurality of sub-plate state detection holes 321c arranged in the vicinity of the lower end edge of the medal rail 210 in a state of being in contact with the protective member 304d. Such an imaging area RLa is an example of a predetermined area including a route formed in the game medium passage portion, and the camera unit 209 that images the predetermined area functions as an example of an imaging unit that images the predetermined area. Further, the plurality of sub-plate state detection holes 321c function as an example of a plurality of holes formed in a predetermined area in the vicinity of the through hole.

<Configuration of connector according to modification>

It is a recess 422 into which the protruding portion 412 of the first member 410 can be inserted and a hole formed in the main body portion 421 from the direction in which the first member 410 is engaged, and a plurality of pin members 413 can be inserted respectively. And a plurality of insertion holes 423 (423a, 423b, 423c, 423d).

  The concave portion 422 is formed in a shape in which a shape having predetermined irregularities in the protruding portion 412 can be inserted. The plurality of insertion holes 423 are arranged around the recess 422, and are formed at positions where the plurality of pin members 413 of the first member 410 can be inserted in a state where the protrusion 412 is inserted and positioned in the recess 422.

In the example shown in FIG. 47B, the plurality of insertion holes 423 are respectively disposed at positions symmetrical to the positions of the plurality of pin members 413 in the example shown in FIG.

  Contact members 414a to 414f to which contact wires are crimped and connected are arranged in six recesses of the protruding portion 412, and contact pins are also crimped and connected to the six recesses of the recess 422. The contact members 424a to 424f to which the conductive wires are connected are arranged, and the protrusions 412 and the recesses 422 are fitted, so that the contact members 414a to 414f and the contact members 424a to 424f come into contact with each other. For example, a power is supplied to the medal selector 301, a ground is provided, and a medal count signal indicating that a medal has passed, or medal determination in the camera unit 209 of the medal selector 301 (see FIG. 40 described later). As a result, communication such as a medal abnormality signal indicating that the medal is abnormal becomes possible.

  The plurality of pin members 413 and the plurality of insertion holes 423 provided corresponding to the plurality of pin members 413 are arranged at different positions according to the classification of the gaming machines. “Classification of gaming machines” includes model, case type, manufacturer, vendor, medal selector, door relay terminal plate type, and the like. Note that the plurality of pin members 413 and the plurality of insertion holes 423 provided corresponding to the plurality of pin members 413 are not limited to the positions where they are arranged, and the quantities may be varied depending on the classification of the gaming machines.

  Moreover, the flat plate part 411 and the protrusion part 412 of the 1st member 410, and the main-body part 421 in which the recessed part 422 of the 2nd member 420 is formed are different colors according to the classification | category of a gaming machine.

In this case, in the connector 400, for example, the first member 410 is connected to the hopper device 51, and the second member 420 is connected to the cabinet-side relay board 44.

<Circuit Configuration of Medal Selector According to Modification>
Next, a circuit configuration of the medal selector 301 according to the modification will be described with reference to FIG.
FIG. 50 is a block diagram illustrating a circuit configuration example of the medal selector 301. The medal selector 301 according to the modification differs from the medal selector 201 (see FIG. 30) of this embodiment in the configuration of the medal solenoid. The medal selector 301 includes a camera unit 209, a medal selection solenoid 308a, and a medal reception solenoid 308b. The medal selector 301 is connected to the main control board 71 via the door relay terminal board 68 as in the medal selector 201. That is, the medal selector 301 is electrically connected to the main control circuit 91. Therefore, the main control circuit 91 can set the medal acceptance solenoid 308b of the medal selector 301 to the ON state or the OFF state.

  The main control circuit 91 has a predetermined game medium input condition (for example, the credit counter is smaller than the maximum value (for example, 50), the game is not being executed, the main control circuit 91 does not detect any error, etc.). If established, a control signal for permitting insertion acceptance by the medal acceptance solenoid 308b is output. The medal reception solenoid 308b is turned on when a control signal for permitting insertion is inputted (the tip of the medal reception medal pressure 213b is retracted from the medal rail 210 and receives a medal). On the other hand, the medal reception solenoid 308b is turned off when the control signal for permitting insertion is not received (the tip of the medal reception medal pressure 213b protrudes into the medal rail 210 and repels the medal). .

  As described above, the main control circuit 91 functions as a control unit that outputs a control signal for permitting the insertion reception by the game medium reception unit when a predetermined game medium insertion condition is satisfied. The medal acceptance solenoid 308b is controlled in the same manner as the medal solenoid 208 of the present embodiment. Such a medal reception solenoid 308b is controlled by the main control circuit 91, which is an example of a control unit, and functions as an example of a game medium reception unit that controls the reception of game media. Note that in a state where no power is supplied to the pachislot machine 1, a state where no power is supplied to the medal selector 301, and a state where the game medium insertion condition is not satisfied, the tip of the medal acceptance medal pressure 213 b is a medal. It will be in the state which protruded from the rail 210. FIG.

  The medal sorting solenoid 308a is controlled to be turned on or off by the control LSI 234 of the camera unit 209. Specifically, the camera unit 209 images a medal inserted into the player and passing through the medal rail 210 and a plurality of determination holes 312 (see FIG. 41) with the CMOS image sensor 232, and the captured image data is controlled by the control LSI 234. Output to. The control LSI 234 performs color determination processing and engraving determination processing based on the image data output from the CMOS image sensor 232 by the control described in the present embodiment, and the medal of the image data matches a predetermined regular medal. It is determined whether or not to do so. When the control LSI 234 determines that the medal does not match the regular medal, the control LSI 234 outputs a control signal for excluding the medal to the medal selection solenoid 308a. The medal sorting solenoid 308a is turned on when a control signal for excluding medals is input (the tip of the medal sorting medal pressure 213a protrudes into the medal rail 210 and repels the medals). On the other hand, if the control LSI 234 determines that the medal matches the regular medal, the control LSI 234 outputs a control signal for accepting the medal to the medal selection solenoid 308a. The medal selection solenoid 308a is turned off when a control signal for receiving a medal is input (the tip of the medal selection medal pressure 213a is retracted from the medal rail 210 and receives the medal). When it is determined that no power is supplied to the pachislot machine 1 or no power is supplied to the medal selector 301, and that a medal in which the control LSI 234 is inserted matches the regular medal, the medal selection medal The tip of the pressure 213a is retracted from the medal rail 210.

  As described above, the medal selection solenoid 308a functions as an example of a game medium selection unit that selects an inserted game medium. The control LSI 234 functions as an example of a determination / selection control unit that determines a game medium and controls the game medium selection unit. The control LSI 234 outputs a control signal for excluding the game medium to the game medium selection means when the input game medium does not match the predetermined game medium, and the input game medium is determined in advance. When the game medium matches the game medium, it outputs a control signal for accepting the game medium to the game medium selection means, thereby functioning as an example of a determination selection control means for selecting a game medium. The medal sorting solenoid 308a is driven when a control signal for removing game media is input from the judgment sorting control means, and the tip of the sorting movable means is routed from the sorting hole formed in the path. It functions as an example of a game medium selection means that protrudes inward. In this modification, the inserted medal is always determined and selected by the medal selection solenoid 308a. For example, in the circuit of the medal selector 301, whether or not the control LSI 234 determines the medal is set. A switch may be provided to determine the inserted medal when the setting switch is in the ON state.

  Further, the camera unit 209 images the sub plate state detection hole 321 c (see FIGS. 44 and 45) of the sub plate 305 with the CMOS image sensor 232, and outputs the captured image data to the control LSI 234. The control LSI 234 performs color determination processing based on the image data output from the CMOS image sensor 232 under the control described in the present embodiment, and the second light guide 262 (FIG. 44) is inserted into the sub-plate state detection hole 321c. It is determined whether or not the shape of the sub-plate state detection hole 321c is imaged by reflection of light from (see FIG. 45). For example, the control LSI 234 continuously captures the shape of the sub-plate state detection hole 321c in the sub-plate state detection hole 321c due to reflection of light from the second light guide 262 for a predetermined time (for example, If it is determined that the sub plate state detection hole 321c has not been picked up or has been picked up, but the shape or position of the hole is different), a signal indicating that the sub plate 305 is in a rotated state is provided. The main control circuit 91 may include a signal indicating the state of the sub-plate 305 in the game medium input condition. Such a camera unit 209 functions as an example of an imaging unit that determines whether or not the auxiliary member is rotating by reflection of light from the irradiation unit in the hole.

Next, the effect of a modification is demonstrated.
When the camera unit 209 images the game medium passing through the base plate portion 304, the camera unit 209 also images the plurality of determination holes 312 of the base plate portion 304 together with the game medium. For example, when the camera unit 209 images a game medium passing through the surface of the base plate portion 304 from the game medium passing side, the plurality of determination holes 312 are partially imaged. The camera unit 209 can determine the passage of the game medium by determining the portions of the plurality of determination holes 312 that have been imaged. At this time, when the anti-reflection sheet is provided in the plurality of determination holes 312 or when the shielding member 312a is not provided, the back side of the base plate portion 304 (the surface through which the game medium passes) in the captured image. When the member disposed on the opposite side) is reflected in the determination hole 312, the light from the first light guide 261 and the like is diffusely reflected, and the determination hole 312 and the base plate portion 304 are The image is difficult to distinguish from other parts. According to the present modification, the shielding member 312a that reflects light from the first light guide 261 and the like is provided according to the plurality of determination holes 312. Therefore, in the image captured by the camera unit 209, the first The light from one light guide 261 and the like is reflected at the plurality of determination holes 312 at a certain level as compared with the other portions of the base plate portion 304, so that the luminance is higher than that of the other portions. Since the shape of the determination hole 312 can be imaged more clearly, the determination accuracy of the plurality of determination holes 312 is improved.
Therefore, by improving the determination accuracy of the game medium, it is possible to provide a game machine that can accurately detect an illegal act of playing a game by misidentifying that a regular game medium is used in the game machine.

  Further, since the shielding member 312a is affixed to the non-imaging surface side of the camera unit 209, the outlines of the plurality of determination holes 312 are clearer than when the shielding member 312a is affixed from the imaging surface side by the camera unit 209 in the base plate portion 304. Thus, the determination accuracy of the plurality of determination holes 312 is improved. In addition, it is possible to prevent the game medium passing through the imaging surface side by the camera unit 209 in the base plate portion 304 from coming into contact with the shielding member 312a and preventing the game medium from being clogged.

  In addition, since the determination hole 312 on the downstream side of the determination hole 312 on the upstream side of the base plate portion 304 is shortened in the traveling direction through which the game medium passes, the passing speed of the game medium becomes relatively slow. By making the determination hole 312 on the downstream side of the base plate portion 304 shorter than the determination hole 312 on the upstream side in the traveling direction through which the game medium passes, the accuracy of imaging the game medium together with the determination hole 312 is improved. Space can be saved without lowering. Further, the determination hole 312 on the upstream side of the base plate 304 is made longer than the determination hole 312 on the downstream side in the traveling direction through which the game medium passes, so that the upstream speed of the game medium is relatively fast. Even on the side, the game medium can be reliably imaged together with the determination hole 312, and the accuracy of the game medium determination process is improved.

Further, for example, even when the game medium is just before heading toward the hopper device 51, when the game medium is not guided to the hopper device 51, a direction different from the direction guided to the hopper device 51 by the first guide portion 321a (for example, a medal) The game medium can be smoothly guided in the direction of the tray unit 34, and the second guiding portion 321b is formed, so that the game medium can be smoothly guided to the medal tray unit 34. Thereby, for example, whether or not it is a regular medal is determined by determination (for example, engraving determination and color determination) by image processing of an image obtained by imaging a game medium passing through the base plate unit 304. Since it can be smoothly guided to the hopper device 51 or the medal tray unit 34, it is possible to prevent the game medium passing through the base plate portion 304 from being clogged and the determination accuracy of the game medium from being lowered.
Therefore, by improving the determination accuracy of the game medium, it is possible to provide a game machine that can accurately detect an illegal act of playing a game by misidentifying that a regular game medium is used in the game machine.

  In addition, when the game medium is not guided to the hopper device 51, the game medium is temporarily dropped from the medal rail 210, and in a state of being urged in the direction of dropping, the medal tray unit provided below is in contact with the inclined surface. Therefore, the game medium can be dropped in a direction orthogonal to the direction in which the game medium passes through the medal rail 210 without falling down. For this reason, for example, when a game medium is imaged from a direction orthogonal to the direction passing through the medal rail 210 and determination is performed by image processing of the captured image, the game medium that has fallen from the medal rail 210 has not fallen down. It is possible to accurately determine whether or not the dropped game medium is moving in the direction of the medal tray unit 34 normally.

  Further, since the first guiding portion 321a of the sub plate 305 has an inclined surface that is inclined toward the slope 203 for guiding the game medium to the hopper device 51, the game medium stays at the entrance of the slope 203, and the slope 203 It is possible to prevent the game medium from being clogged at the entrance.

Further, in addition to the main control circuit 91 for determining whether or not to accept the game medium depending on whether or not a predetermined game medium insertion condition is satisfied, whether or not the inserted game medium matches a predetermined game medium. To eliminate or accept the inserted game media. Accordingly, the medal selector 301 determines the effectiveness of the inserted game medium separately from the conventional selector function in which the game medium can be inserted or disabled by the main control circuit 91 that controls the game, and selects the medal. Since the illegal game medium can be eliminated by the solenoid 308a, it is possible to eliminate the goto action.
Therefore, apart from accepting or accepting game media, by selecting game media for fraudulent acts, it is possible to accurately detect fraudulent acts that cause games to be misidentified that legitimate game media are used. Can be provided.

  In addition, since a configuration for removing game media from the medal rail 210 through which game media pass (configuration for selecting game media due to fraud) is provided on the back side of the surface on which the medal rail 210 is formed. The medal selector 301 can be downsized as compared with the case where such a configuration is provided separately from the base plate portion 304 on which the medal rail 210 is formed. Further, the medal sorting solenoid 308a is driven when a control signal for removing the game medium is received, and the tip of the medal sorting medal pressure 213a protrudes into the medal rail 210, so that the medal sorting solenoid 308a is always driven. Thus, the power consumption of the medal selector 301 can be reduced as compared with the case where the medal selection medal pressure 213a is moved.

  In addition, the medal reception solenoid 308b excludes game media upstream from the position where the medal selection solenoid 308a selects game media with respect to the passage direction of the game media on the base plate portion 304. For this reason, the medal selection solenoid 308a can select game media downstream from the position where the medal reception solenoid 308b excludes game media. Therefore, the medal reception solenoid 308b is upstream from the position where the medal reception solenoid 308b excludes game media. As compared with the case where the game media are selected, the processing time for the control LSI 234 to discriminate the game media can be increased. Therefore, it is possible to reduce the processing load of the determination in the control LSI 234.

  In the medal selector 301, the game medium drops from the medal rail 210 of the base plate portion 304 when the sub plate 305 is rotated. When the sub plate 305 is not rotated, light from the second light guide 262 and the like is reflected in the plurality of sub plate state detection holes 321c of the sub plate 305, and the sub plate 305 is rotated. In this state, the light from the second light guide 262 and the like is reflected differently from the case where the sub plate 305 is not rotated. The camera unit 209 determines whether or not the sub plate 305 is rotating based on such reflection of light from the second light guide 262 and the like.

  Thereby, it can be determined whether or not the sub plate 305 is rotated and the game medium falls from the medal rail 210 (whether or not the game medium can be received). For example, when the sub plate 305 is continuously rotated, or when the game medium is received even though the sub plate 305 is rotated and the game medium is dropped from the medal rail 210. It is highly likely that fraudulent activity has been conducted. Therefore, by determining whether or not a game medium can be accepted, a gaming machine capable of detecting a fraudulent act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine with high accuracy is provided. it can.

  In addition, the camera unit 209 performs image processing on the captured image of the predetermined region, and thereby the image in a state in which the sub plate 305 is not rotated (light is reflected in the sub plate state detection hole 321c); The difference from the image of the state in which the sub plate 305 is rotated (the state in which light is not reflected in the sub plate state detection hole 321c) becomes clearer, and it is determined whether or not the sub plate 305 is rotated. Improves accuracy. Therefore, by accurately determining whether or not a game medium can be accepted, a game capable of detecting a fraudulent act of playing a game by misidentifying that a regular game medium is used in a gaming machine with high accuracy. Can provide a machine.

In the gaming machine, the plurality of pin members 413 and the plurality of insertion holes 423 of the connector 400 that electrically connect the medal selector 301 that detects the insertion of the gaming medium and the door relay terminal board 68 are classified into the classification of gaming machines. It arranges in a different position according to (for example, model etc.). Thereby, even if the 2nd member 420 of the game machine of another classification is attached to the 1st member 410 attached to a certain game machine, it does not engage mutually. For this reason, even if the first member 410 or the second member 420, which is classified differently from the gaming machine being assembled, is attached, the first member 410 and the second member 420 do not engage with each other. You can immediately see that it is installed.
Accordingly, a connection member is provided that can prevent human error that occurs when a device for detecting a fraudulent act of playing a game with high accuracy is misidentified that a legitimate gaming medium is used in the gaming machine. it can.

Further, in the gaming machine, a plurality of pin members 413 and a plurality of insertion holes 423 of the connector 400 that electrically connect the hopper device 51 that stores the game media and discharges the stored game media and the door relay terminal plate 68 and the like. Are arranged at different positions according to the classification (for example, model) of the gaming machine. Thereby, even if the 2nd member 420 of the game machine of another classification is attached to the 1st member 410 attached to a certain game machine, it does not engage mutually. For this reason, even if the first member 410 or the second member 420, which is classified differently from the gaming machine being assembled, is attached, the first member 410 and the second member 420 do not engage with each other. You can immediately see that it is installed.
Therefore, human errors that occur when the hopper device 51 is attached to a gaming machine equipped with a device for detecting with high accuracy a fraudulent act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine. A connecting member that can be prevented can be provided.

In addition, the color of the protruding portion 412 and the recessed portion 422 indicates whether or not the connector 400 is suitable for the classification of the gaming machine being assembled. In addition, even if the first member 410 or the second member 420, which is classified differently from the gaming machine being assembled, is attached, it is not necessary to engage them with each other. It is immediately apparent that the wrong connector 400 is attached.
Therefore, a connection that can more reliably prevent human errors that occur when attaching to a gaming machine a device for accurately detecting fraudulent acts of playing a game by misidentifying that a regular gaming medium is used in the gaming machine A member can be provided.

<Medal selector according to modification 2>
Next, the medal selector 401 according to the modified example 2 will be described with reference to FIGS. 51 to 53, particularly focusing on the solenoid driving unit 402. 51 is a block diagram showing the overall configuration of the medal selector 401 including the solenoid drive unit 402, FIG. 52 shows a specific circuit configuration of the solenoid drive unit 402, and FIG. 53 shows the solenoid drive unit 402 as a medal. It is a time chart which shows the time change of the voltage and electric current which are output with respect to the selection solenoid 308a.

  FIG. 51 is a block diagram illustrating a configuration example of the medal selector 401. The medal selector 401 according to the second modification differs from the medal selector 201 according to the present embodiment (see FIG. 30) in the configuration of the medal solenoid, and is different from the medal selector 301 according to the modification (see FIG. 50) as a solenoid driving unit. It differs in having 402. Therefore, description of components common to the medal selector 201 (see FIG. 30) and the medal selector 301 (see FIG. 50) is omitted or simplified here.

  As shown in FIG. 51, the medal selector 401 includes a camera unit 209, a medal selection solenoid 308a, a medal reception solenoid 308b, and an LED group 233. The camera unit 209 includes a control LSI 234, a CMOS image sensor 232, a solenoid drive unit 402, and an LED drive unit 252.

  Similar to the medal selectors 201 and 301, the medal selector 401 is electrically connected to the main control circuit 91 included in the main control board 71 that performs control related to the game via the door relay terminal board 68. Therefore, the main control circuit 91 can set the medal acceptance solenoid 308b of the medal selector 401 to the ON state or the OFF state. Such a configuration is common to the medal selector 301 (see FIG. 50) according to the modification.

  On the other hand, in the medal selector 401, the medal selection solenoid 308a is different in connection mode from the medal reception solenoid 308b. The medal selection solenoid 308a is driven by a solenoid driving unit 402 included in the camera unit 209 constituting the medal selector 401, and the solenoid driving unit 402 is controlled by a control LSI 234 included in the camera unit 209. .

  The medal selection solenoid 308a is controlled to be in an ON state or an OFF state by the control LSI 234 of the camera unit 209 via the solenoid driving unit 402. Specifically, the camera unit 209 images a medal that is inserted into the medal slot 21 of the pachislot machine 1 by the player and passes through the medal rail 210 and a plurality of determination holes 312 (see FIG. 41) by the CMOS image sensor 232. The captured image data is output to the control LSI 234.

  The control LSI 234 performs color determination processing and engraving determination processing based on the image data output from the CMOS image sensor 232 by the control described in this embodiment, and the medal of the image data is a predetermined regular medal. It is determined whether or not. When the control LSI 234 determines that the medal is not a regular medal, the control LSI 234 outputs an operation signal (ON signal) to the solenoid driving unit 402 so as to play an illegal medal by the medal selection solenoid 308a.

  When an ON signal output from the control LSI 234 is input, the solenoid driving unit 402 applies a predetermined voltage to the medal selection solenoid 308a for a predetermined period. The medal selection solenoid 308a is turned on when a predetermined voltage is applied from the solenoid driving unit 402. In this case, the tip of the medal selection medal pressure 213a protrudes into the medal rail 210 and plays the medal.

  The medal sorting solenoid 308a is controlled by a so-called normally-off method. That is, the period from when the operation signal (ON signal) is input to when the operation stop signal (OFF signal) is input is in the ON state, and other periods are in the OFF state. For example, when it is determined that power is not supplied to the pachislot machine 1, power is not supplied to the medal selector 401, and a medal with the control LSI 234 inserted matches a regular medal, a predetermined voltage is applied from the solenoid driving unit 402. In a state where no is applied, the tip of the medal sorting medal pressure 213a is retracted from the medal rail 210 (OFF state). Further, the medal selection solenoid 308a is controlled to be in an ON state for a predetermined period for each illegal medal, and is controlled to be in an OFF state when the predetermined period expires. For example, when two illegal medals are inserted in succession, the control to the ON state is performed twice by applying a predetermined voltage for a predetermined period.

  As described above, the main control board 71 functions as a control unit related to a game, and the medal selector 401 functions as a game medium detection unit that detects a game medium used for a game. The medal selector 401 includes a medal selection solenoid 308a that functions as a game medium selection unit that selects an inserted game medium, a control LSI 234 that functions as a game medium determination unit that determines a game medium, and a medal selection that is connected to the control LSI 234. A solenoid drive unit 402 that functions as sorting drive means for driving the solenoid 308a is provided.

  In the second modification, when the operation signal (ON signal) output from the control LSI 234 is input, the solenoid driving unit 402 applies a start-up voltage to the medal selection solenoid 308a for a predetermined time, and then applies to the medal selection solenoid 308a. By applying a holding voltage lower than the starting voltage, the excitation state of the medal sorting solenoid 308a is held.

  In this case, the activation voltage is higher than the minimum voltage required to activate the medal sorting solenoid 308a. Further, the holding voltage is a voltage lower than the starting voltage, and is a minimum voltage required to hold the excitation state of the medal selection solenoid 308a.

  The medal selector 401 further includes a medal reception solenoid 308b that is controlled by the main control board 71 and functions as a game medium reception unit that accepts or removes a medal upstream from a position where the medal selection solenoid 308a selects a medal. .

  When an abnormality is found in the solenoid drive unit 402, the main control board 71 causes the medal reception solenoid 308b to exclude the game medium, and the control LSI 234 outputs an ON signal (operation signal) to the solenoid drive unit 402. It is configured not to.

  As an example of the abnormality of the solenoid driving unit 402, as a result of excessively frequent ON signals being input to the solenoid driving unit 402 due to the frequent use of unauthorized medals, the solenoid driving unit 402 A case where the calorific value exceeds a certain value may be considered.

  In the second modification, the inserted medal is always determined and selected by the medal selection solenoid 308a. For example, in the circuit of the medal selector 401, a setting switch for determining whether or not the control LSI 234 determines a medal. The inserted medals may be determined only when the setting switch is in the ON state, and the inserted medals may not be determined when the setting switch is in the OFF state.

  In addition, when an abnormality is found in the solenoid drive unit 402 described above, when it is determined that a predetermined number of metals are not continuously regular medals, medals determined not to be regular medals within a predetermined period. If the number of cards exceeds the threshold, or if another non-regular medal is detected within a certain period of time after the non-regular medal is detected, it is considered that the player has been malicious and the medal The reception solenoid 308b may be made to exclude the game medium, and in this case, the player is used by using the liquid crystal display device 11, speakers 58, 64, 65L, 65R, LEDs 85, 233La, 233Lb, 233Lc, and the like. May be warned.

  FIG. 52 is a circuit configuration diagram showing a specific circuit configuration of the solenoid drive unit 402. The solenoid drive unit 402 includes a PWM driver IC 403, capacitors C1, C2, C3 connected to external connection terminals of the PWM driver IC 403, resistors R1, R2, and the like. An operation signal (ON signal) and an operation stop signal (OFF signal) output from the control LSI 234 are input to the PWM driver IC 403. The PWM driver IC 403 outputs a status signal that is a result of self-diagnosis to the control LSI 234. The PWM driver IC 403 drives the medal selection solenoid 308a by applying a predetermined voltage to the medal selection solenoid 308a for a predetermined period.

  The PWM driver IC 403 is an integrated circuit (IC) having a pulse width modulation function for performing modulation by changing the duty ratio of a pulse wave. As the PWM driver IC 403, a commercially available integrated circuit having such a function may be used. The PWM driver IC 403 includes external connection terminals such as an IN terminal, a DI terminal, an OSC terminal, a Du terminal, an OUT terminal, a + Vs terminal (not shown), and a Status terminal. It should be noted that numerical values such as the capacitance, resistance value, input / output voltage value, delay time, oscillation frequency, and duty ratio exemplified below are merely examples, and the present invention is not limited to the exemplified numerical values.

  The IN terminal is connected to a control LSI 234 that controls the PWM driver IC 403, and is a terminal to which an ON signal and an OFF signal output from the control LSI 234 are input. Specifically, in the second modification, the ON signal is a voltage of 2.2 V to 5.5 V, and the OFF signal is a voltage of 1.2 V or less.

  The DI terminal is a terminal for setting a delay time when the medal sorting solenoid 308a is activated. In the second modification, a capacitor C3 having a capacity of 9100 pF (picofarad) is connected, and the tip of the capacitor C3 is connected. Grounded. Thereby, the delay time at the start of the operation of the PWM driver IC 403 is set to 10 ms (milliseconds).

  The OSC terminal is a terminal for setting an oscillation frequency. In the second modification, a resistor R1 having a resistance value of 205 kΩ (kiloohm) and a capacitor C1 having a capacitance of 10 μF (microfarad) are connected in parallel. The tip of the resistor R1 and the capacitor C1 is grounded. Thus, the oscillation frequency of the PWM driver IC 403 is set to 25 kHz (kilohertz).

  The Du terminal is a terminal for setting the duty ratio. In the second modification, a resistor R2 having a resistance value of 82 kΩ and a capacitor C2 having a capacitance of 10 μF are connected in parallel, and the resistor R2 and the capacitor C2 The tip is grounded. Thereby, the duty ratio of the PWM driver IC 403 is set to 10%.

  The OUT terminal is a terminal that is connected to the medal selection solenoid 308a driven by the PWM driver IC 403 and to which a voltage is applied to the medal selection solenoid 308a. In the second modification, as shown in FIG. 53, a DC 12V starting voltage is applied in the delay time zone, and in the PWM control time zone, the 12V is multiplied by the above-described duty ratio of 10%. A holding voltage of 1.2 V (average value) which is the obtained value is applied to the medal sorting solenoid 308a.

  A + Vs terminal (not shown) is connected to the medal selector 401 and supplied from the power supply board 53b (see FIG. 27). In the second modification, a DC voltage of 12V is supplied from the power supply substrate 53b to the PWM driver IC 403.

  The Status terminal is connected to the control LSI 234 that controls the PWM driver IC 403, and is a terminal to which status signals (OK signal and NG signal) output from the PWM driver IC 403 to the control LSI 234 are output. An OK signal is output when the PWM driver IC 403 is normal, and an NG signal is output when the PWM driver IC 403 is abnormal (for example, when the amount of heat generation exceeds a threshold). In the second modification, specifically, the OK signal is a voltage of 4.5V, and the NG signal is a voltage of 0.4V.

  Next, the effect of the modification 2 is demonstrated with reference to FIG. 53 (FIGS. 53A and 53B) shows the configuration of the medal selector 401 and the solenoid drive unit 402 shown in FIGS. 51 and 52. After the ON signal is input from the control LSI 234 to the PWM driver IC 403, the PWM driver IC 403 is driven. The medal selection solenoid 308a is activated, and then the OFF signal is input from the control LSI 234 to the PWM driver IC 403, and then the PWM driver IC 403 in the time zone (t0 to solenoid OFF) until the demagnetization in the medal selection solenoid 308a is completed. It is a figure which shows the time change of the voltage and electric current which are applied to the medal selection solenoid 308a. FIG. 53A shows the temporal change of the voltage, with the voltage on the vertical axis and time on the horizontal axis. FIG. 53B shows the temporal change of the current, with current on the vertical axis and time on the horizontal axis.

  First, with reference to FIG. 53A, the operation of controlling the voltage in the PWM driver IC 403 will be described. When the control LSI 234 constituting the game medium determining means determines that the medal inserted into the pachislot machine 1 by the player is not a regular medal, the control LSI 234 sends an activation signal to the PWM driver IC 403 included in the solenoid drive unit 402. (ON signal) is output. When the ON signal from the control LSI 234 is input to the PWM driver IC 403 (t0), the DC voltage of 12V is maintained in the time zone (t0 to t1) of the delay time (10 ms) therefrom. Such a voltage of 12 V is referred to as “starting voltage”, and the starting voltage is higher than a minimum voltage required to start the medal sorting solenoid 308a.

  After the delay time has elapsed, PWM control by the PWM driver IC 403 is started (t1), and a voltage of 1.2 V (12 V × duty ratio 10%) is generated during the PWM control period from t1 to t2. Such a voltage of 1.2 V is referred to as a “holding voltage”, and the holding voltage is a minimum voltage required to hold the excitation state of the medal selection solenoid 308a.

  Thereafter, the control LSI 234 outputs an OFF signal to the PWM driver IC 403 at a time (t2) when a predetermined period has elapsed from the time (t0) when the ON signal is output. When the OFF signal is input from the control LSI 234 to the PWM driver IC 403, the PWM driver IC 403 stops applying the voltage of 1.2V to the medal selection solenoid 308a.

  Next, with reference to FIG. 53B, the temporal change in voltage and current applied from the PWM driver IC 403 to the medal selection solenoid 308a will be described. Note that the temporal change in voltage and the operation of the medal selection solenoid 308a overlap with the description of FIG. 53A described above, and therefore the description is omitted or simplified.

  When an ON signal is input to the PWM driver IC 403 (t0), in the time zone (t0 to t1) from the delay time (10 ms), the medal from the PWM driver IC 403 is as described above with reference to FIGS. A starting voltage of DC 12V is applied to the sorting solenoid 308a. At this time, the current applied to the medal sorting solenoid 308a becomes higher as time passes as shown in FIG. 53B. Such a current flows through the coil of the medal selection solenoid 308a. As a result, a magnetic field is generated in the coil, and the movable iron core of the medal selection solenoid 308a enters the coil. The movable iron core that has entered the coil continues to move in the coil until it finally comes into contact with the fixed iron core, that is, until it is attracted to the fixed iron core.

  At this time, as shown in FIG. 53B, the medal selection solenoid 308a is activated 8 ms after the application of the DC 12V voltage from the PWM driver IC 403 is started (t0). The leading end portion of the medal pressure 213a protrudes into the medal rail 210, and the medal determined to be not a regular medal is turned on.

  In this way, when the movable iron core starts moving in the coil toward the fixed iron core in the medal sorting solenoid 308a, the current that has increased with the passage of time decreases once, and the movable iron core is attracted to the fixed iron core. When it is done, the current stops decreasing and begins to rise again. In the second modification, it is assumed that the start-up is completed when the movable iron core of the medal sorting solenoid 308a is attracted to the fixed iron core (when the current stops decreasing and starts to rise again). Therefore, the operation time of the medal selection solenoid 308a is the start time from the time (t0) when the ON signal is input to the PWM driver IC 403 to the time when the movable iron core is attracted to the fixed iron core. In the second modification, the activation time is 8 ms. The current that has started to rise again continues to rise until the time point (t1) when the delay time expires.

  After the delay time (after t1), as described above with reference to FIG. 53A, the PWM control period (t1 to t2) is entered, and the result of PWM control until the time (t2) when the OFF signal is input to the PWM driver IC 403. The 1.2V holding voltage is continuously applied from the PWM driver IC 403 to the medal selection solenoid 308a. As described above, when the delay time expires (t1), the voltage applied to the medal selection solenoid 308a drops from 12V to 1.2V at a stretch, so that the current rapidly decreases to a certain level, and then the current is constant. Keep the value.

  Thereafter, when the OFF signal from the control LSI 234 is input to the PWM driver IC 403 at a time point (t2) when a predetermined period has elapsed from the ON signal (t0), the PWM driver IC 403 receives 1.2 V with respect to the medal selection solenoid 308a. Since the application of the holding voltage is stopped, the voltage and the current value applied to the medal selection solenoid 308a at that time become zero.

  When no current is applied, the magnetic field generated in the coil of the medal sorting solenoid 308a is also extinguished. The time until the magnetic field disappears is called “demagnetization time”, and the demagnetization time in Modification 2 is 12 ms.

  As shown in FIG. 53B, in the medal selection solenoid 308a, the demagnetization is completed after 12 ms, which is the demagnetization time, from the stop of the application of the voltage of 1.2 V, and the medal selection medal that has entered the medal rail 210 is completed. The tip of the pressure 213a is retracted from the medal rail 210 and is turned off.

  As described above, the activation time of the medal sorting solenoid 308a in the second modification is 8 ms and the demagnetization time is 12 ms. The activation time and the demagnetization time are PWM by the normal solenoid, that is, the PWM driver IC 403 in the second modification. Compared to the start-up time and demagnetization time in a solenoid that does not go through PWM control such as control, the time is significantly shortened.

  For example, the medal reception solenoid 308b is controlled to be in the ON state by continuing to apply a constant voltage directly from the main control circuit board 71 constituting the control means without going through the PWM control in the PWM driver IC 403. . More specifically, the medal reception solenoid 308b is activated by continuing to apply a voltage almost equal to the minimum necessary voltage for activating the medal reception solenoid 308b (without time change). The excitation state of the medal reception solenoid 308b is held by the constant voltage. Here, since the constant voltage is a voltage that can activate the medal reception solenoid 308b as described above, the voltage is higher than a minimum voltage required to maintain the excitation state of the medal reception solenoid 308b. In the configuration of the medal reception solenoid 308b, the activation time and the demagnetization time are within the range of general values for the solenoid, the activation time is 300 to 500 ms, and the demagnetization time is 1000 to 2000 ms.

  If this numerical value is compared with the start time 8 ms and the demagnetization time 12 ms of the medal selection solenoid 308 a having the configuration of the modified example 2, the start time and the demagnetization time of the medal selection solenoid 308 a are determined by the solenoid driver 402 (PWM driver IC 403) It can be understood that the operation is greatly shortened by the voltage control function by the used PWM control.

  As described above, in the second modification, the activation time and the demagnetization time of the medal selection solenoid 308a can be shortened by the activation voltage of 12 V (the voltage at the delay time in FIG. 53) that is the applied voltage in the delay time period (t0 to t1). ) Is a voltage higher than the minimum voltage required to activate the medal sorting solenoid 308a, and the holding power 1.2V (PWM control in FIG. 53), which is the applied voltage in the PWM control time zone (t1 to t2). This is because the voltage during the period is the minimum voltage necessary to maintain the excitation state of the medal selection solenoid 308a.

  On the other hand, in general, in a gaming machine using a medal as a game medium, in order to reliably play an illegal medal, the medal moves to a medal pressure position along the medal rail in the gaming machine after the medal is inserted. As described above, there is a time restriction that the determination of the medal and the driving of the solenoid that causes the medal pressure to enter the medal rail must be executed within the time.

  Therefore, in view of such time constraints, it can be understood that the time required for medal discrimination by the control LSI 234 can be made longer than before by reducing the activation time of the medal selection solenoid 308a. For this reason, according to the configuration of the second modification, the activation time of the solenoid is shortened to secure a sufficient medal determination time and the medal determination accuracy is improved, thereby making it mistaken that a regular game medium is used. Thus, it is possible to provide an effect that a gaming machine capable of detecting an illegal act of playing a game with high accuracy can be provided.

  In addition, since the degaussing time is also shortened, it becomes possible to respond to the next medal as soon as possible when it is necessary to continuously play medals. Since the time required for determining medals can be made longer than before, the accuracy of determining medals can be increased, and the above-described effects can be further enhanced.

  Further, the holding power 1.2V (the voltage in the PWM control period in FIG. 53), which is the applied voltage during the PWM control period, can be suppressed to the minimum voltage necessary for maintaining the excitation state of the medal selection solenoid 308a. The amount of heat generation and power consumption of the solenoid 308a can be suppressed, and as a result, the medal selection solenoid 308a itself and other parts of the pachislot machine 1 installed in the vicinity thereof can be prevented from malfunctioning and aged deterioration. An effect can be produced.

  The medal selector 401 further includes a medal receiving solenoid 308b that is controlled by the main control board 71 and functions as a game medium receiving means for receiving or removing medals upstream from the position where the medal selection solenoid 308a selects medals.

When the amount of generated heat exceeds the threshold value, and as a result, an NG signal is output from the Status terminal of the PWM driver IC 403, all the metal thrown by the medal reception solenoid 308b will be repelled, so such a malicious player Can prevent the occurrence of damages caused by misconduct.

  In addition to the case where an abnormality is found in the solenoid drive unit 402 described above, when it is determined that a predetermined number of metals are not continuously regular medals, the medals determined not to be regular medals within a predetermined period. If the number of cards exceeds the threshold, or if another non-regular medal is detected within a certain period of time after the non-regular medal is detected, it is considered that the player has been malicious and the medal The reception solenoid 308b may be made to exclude the game medium, and in this case, the player is used by using the liquid crystal display device 11, speakers 58, 64, 65L, 65R, LEDs 85, 233La, 233Lb, 233Lc, and the like. May be warned.

  With this configuration, it is possible to prevent the damage caused by the malicious player's fraud, and to prevent further fraud.

  In the second modification, a gaming machine (pachislot machine 1) provided with a control means (main control board 71) for controlling the game and a game medium detection means (medal selector 401) for detecting a game medium used in the game. However, the present invention is a so-called medal counter (a game counter described later) having a configuration that includes a game medium detection unit that detects a game medium used in a game but does not include a control unit that controls a game. It can also be applied to the devices 500, 600, 700).

  This configuration shortens the solenoid start-up time, secures sufficient medal determination time, and improves medal determination accuracy, thereby increasing the fraudulent act of misrecognizing that a legitimate game medium is used and playing a game. A gaming device that can be detected with high accuracy can be provided.

For example, if the lending unit loaned in the hall where this slot machine is installed is a medals with 20 yen per piece and medals with 5 yen per piece having the same diameter and only different colors and stamps (patterns), Cannot be determined. For this reason, a gaming machine that handles a medal with a lending unit price of 20 yen as a regular medal could not detect an illegal act of playing a game using a medal with a lending unit price of 5 yen (unauthorized medal). .

In addition, the slot machine described in Patent Document 1 is attached to a medal lent out in a hall in which a gaming machine is installed, a medal lent out in another hall, or a gaming machine purchased at a used machine dealer. If a medal or a counterfeit medal (including an instrument pretending to be a medal) has the same diameter and differs only in color or stamp (pattern), these cannot be discriminated. For this reason, it has been difficult to detect (detect) an illegal act of playing a game using medals other than regular medals (unauthorized medals).

The determination process can be performed with high accuracy.
[Effect of the invention]

Lens holding means (for example, a lens holder 275 and a lens unit 287) that is held in front of the image sensor, and the lens holding means includes at least a resin component and a predetermined blending ratio (for example, the resin component) GF is mixed with glass filler mixed at 30%), and the blending ratio is a first blending ratio or a second blending ratio (for example, GF is 10 to 40%). It is a gaming machine.

  According to the first aspect, it is possible to obtain the image data of the passing object by the imaging unit using the introduction light as a light source, and to smoothly perform the determination process by the medium determination unit. In particular, since the lens holding means is formed by at least a resin component and a glass filler mixed at a blending ratio of 10 to 40% with respect to the resin component, structural distortion due to temperature rise, for example, a condensing lens is a lens. The distortion caused by the pressure action when it interferes with the holding means can be deformed so as to cancel out on the lens holding means side, and can be canceled and suppressed or suppressed, so that high-quality imaging can be performed without causing defocus due to structural distortion.

However, since the structural distortion is eliminated, it is only necessary to take measures for imaging processing for lens distortion that can be analyzed in advance, and no additional structural distortion countermeasure parts are added. The manufacturing cost of the lens holding mechanism can be reduced without incurring unnecessary cost increase, which contributes to the cost reduction of the gaming machine.

  According to the second aspect, the lens holding means has a lens holding structure that holds a plurality of condenser lenses in a multilayer shape in front of the image sensor, and prevents structural distortion with each condenser lens. Then, it is deformed so as to cancel out at the lens holding means side formed by at least the resin component and the glass filler mixed at a blending ratio of 10 to 40% with respect to the resin component, and is canceled or suppressed or suppressed. Therefore, it is possible to realize a gaming machine that can perform high-precision determination processing by performing high-quality imaging without causing a focus shift due to structural distortion.

  A third aspect of the present invention is a gaming machine characterized in that the resin component is a liquid crystal polymer material.

According to the third aspect, since the resin component is a liquid crystal polymer material rich in heat resistance and rigidity, it does not cause thermal deformation due to a temperature rise, and enables high-quality image acquisition and highly accurate determination processing. A gaming machine capable of performing the above can be realized.

  However, the slot machine described in Patent Document 1 cannot detect an illegal act performed using an illegal medal without using an instrument such as a plate-like body. For example, if the lending unit loaned in the hall where this slot machine is installed is a medals with 20 yen per piece and medals with 5 yen per piece having the same diameter and only different colors and stamps (patterns), Cannot be determined. For this reason, a gaming machine that handles a medal with a lending unit price of 20 yen as a regular medal could not detect an illegal act of playing a game using a medal with a lending unit price of 5 yen (unauthorized medal). .

In addition, the slot machine described in Patent Document 1 is attached to a medal lent out in a hall in which a gaming machine is installed, a medal lent out in another hall, or a gaming machine purchased at a used machine dealer. If a medal or a counterfeit medal (including an instrument pretending to be a medal) has the same diameter and differs only in color or stamp (pattern), these cannot be discriminated. For this reason, it has been difficult to detect (detect) an illegal act of playing a game using medals other than regular medals (unauthorized medals).
Also, in the slot machine described in Patent Document 2, a wrong camera token is determined using a CCD camera. However, since the space inside the gaming machine is limited, the distance between the rail for flowing medals and the lens of the CCD camera becomes short, the angle of view that can be captured by the CCD camera is narrowed, and the imageable range is narrowed. For this reason, there is a problem that an image for determining an illegal medal becomes an inappropriate image such as a medal being overrun, and the accuracy of the determination is lowered.

The object of the present invention is to ensure the imageable range necessary for accurately detecting an illegal act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine based on the captured image. Is to provide a simple gaming machine.
[Means for solving problems]

  In order to achieve the above object, the present invention provides a gaming machine having the following configuration. Although each component corresponding to the embodiment is described in parentheses, the configuration of the present invention is not limited to this.

The first form according to the present invention is:
A slot (for example, medal slot 21) into which a game medium can be inserted;
Game medium detection means (for example, medal selector 201) for detecting the game medium inserted from the insertion slot,
The game medium detection means includes
A passage forming portion (for example, base plate portion 204) in which a passage (for example, medal rail 210) through which the game medium passes is formed;
Imaging means (for example, camera unit 209) for imaging a passing object that is an object passing through the passage;
Holding means (for example, an intermediate member 293) arranged facing the passage and holding the imaging means,
The holding means is
An opening (for example, an opening 293a) serving as an opening region that does not interfere with the angle of view of the imaging unit is formed,
The gaming machine is characterized in that a protruding portion (for example, a protruding portion 293b) is formed on the periphery of the opening portion so as to protrude from a surface opposite to the passage and where the imaging means is disposed.

  According to the first form, the gaming machine includes an insertion slot and a game medium detecting means. The slot is provided so that a game medium can be inserted. The game medium detection means detects a game medium thrown from the slot, and has a passage forming part, an imaging means, and a holding means. The passage formation part is formed with a passage through which the game medium passes. The imaging means images a passing object that is an object passing through the passage. The holding means is disposed facing the passage and holds the imaging means. The holding means is formed with an opening that is an opening region that does not interfere with the angle of view of the imaging means. The holding means protrudes from the surface opposite to the passage at the periphery of the opening, and the imaging means is disposed. A protruding portion is formed.

In this way, a protrusion is formed on the surface of the opening opposite to the passage through which the passing object passes at the periphery of the opening that is an opening region that does not interfere with the angle of view, and the imaging means is disposed on the protrusion. Thus, the imaging unit and the passage can be further separated, the angle of view that can be captured by the imaging unit is widened, and the imageable range is widened. Therefore, it is possible to image a passing object passing through the passage in a wider range.
Accordingly, a gaming machine capable of ensuring a captureable range necessary for accurately detecting an illegal act of playing a game by misidentifying that a regular gaming medium is used in the gaming machine based on the captured image. Can be provided.
In addition, by forming a protrusion on the periphery of the opening, the strength of the holding means is improved, the holding means is bent, the optical axis of the imaging means held by the holding means is displaced, and the passing object is moved at an appropriate position. It is possible to prevent a situation in which imaging cannot be performed and the accuracy of detecting fraud is reduced.

The second form according to the present invention is:
The holding means is a gaming machine characterized in that a taper process is performed in which the inner dimension of the opening extends toward the passage at the periphery of the opening.

According to the second embodiment, the edge of the opening on the side of the passage enters the imaging range of the imaging means and passes through the passage because the inner peripheral dimension of the opening is tapered on the periphery of the opening. It is possible to prevent the range in which the passing object can be imaged from becoming narrow. In addition, by tapering the peripheral passage side of the opening, when a passing object passing through the passage falls to the holding means side and contacts the peripheral edge of the opening, the passing object can be smoothly received. Therefore, it can be prevented that the passing object is clogged in contact with the peripheral edge of the opening, the passing object cannot be imaged at an appropriate position, and the accuracy of detecting fraud is reduced. Further, by tapering the peripheral passage side of the opening, it is possible to prevent foreign matters such as dust from accumulating on the peripheral edge of the opening. Therefore, it is possible to prevent foreign matter from collecting around the periphery of the opening, and this foreign matter is imaged by the imaging means together with the passing object, thereby reducing the accuracy of detecting fraud.
Therefore, it is possible to secure the imageable range necessary for detecting a fraudulent act of playing a game by misidentifying that a legitimate game medium is used in the gaming machine with high accuracy based on the captured image. A gaming machine that can prevent an appropriate image from being captured can be provided.

The third form according to the present invention is:
A translucent plate (for example, an acrylic resin plate 296a) is provided between the holding unit and the imaging unit, closes the opening, and is formed of a translucent material. It is a gaming machine.

According to the third aspect, since the translucent plate that closes the opening is disposed between the holding unit and the imaging unit, foreign substances such as dust can be prevented from entering the imaging unit from the passage side. Therefore, it is possible to prevent a foreign object from entering the inside of the image pickup unit and the image pickup unit from appropriately picking up a passing object, thereby preventing the accuracy of detecting fraud. Moreover, even if such a foreign object adheres to the light transmitting plate, the position of the light transmitting plate to which the foreign object has adhered is shorter than the imaging distance of the image capturing means by keeping the imaging means focused on the passage. There is little influence on the imaging of the passing object by the imaging means.
Therefore, it is possible to secure the imageable range necessary for detecting a fraudulent act of playing a game by misidentifying that a legitimate game medium is used in the gaming machine with high accuracy based on the captured image. A gaming machine that can prevent an appropriate image from being captured can be provided.
[Effect of the invention]

  According to the present invention, it is possible to secure an imageable range necessary for accurately detecting an illegal act of playing a game by misidentifying that a regular game medium is used in the gaming machine based on the captured image. Can be provided.
