Description

  The present invention relates to a gaming machine.

  Conventionally, a game called pachislot, comprising a plurality of reels each having a plurality of symbols arranged on each surface, a start switch, a stop switch, a stepping motor provided for each reel, and a control unit. The machine is known. The start switch detects that the start lever has been operated by the player after a game medium such as a medal has been inserted into the gaming machine (hereinafter also referred to as “start operation”), and starts the rotation of all reels. Output the requested signal. The stop switch detects that a stop button provided for each reel has been pressed by the player (hereinafter also referred to as “stop operation”), and outputs a signal requesting the rotation of the corresponding reel to stop. To do. The stepping motor transmits the driving force to the corresponding reel. Further, the control unit controls the operation of the stepping motor based on the signals output from the start switch and the stop switch, and performs the rotation operation and stop operation of each reel.

  In such a gaming machine, when a start operation is detected, lottery processing using random numbers (hereinafter referred to as “internal lottery processing”) is performed on the program, and the result of the lottery (hereinafter referred to as “internal winning combination”). 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.

  In addition, such a gaming machine is provided with a medal selector for detecting a medal inserted at the end of the medal slot. In addition, for this medal selector, a medal (illegal medal) that is not a proper medal (regular medal) is inserted into the medal insertion slot, or a device is inserted into the medal insertion slot, so that a regular medal is inserted into the gaming machine. Measures are taken against fraudulent acts in which a game is played by misunderstanding that it has been inserted.

  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 is described that detects fraud using a tool such as a body.

JP 2002-342814 A JP 2006-271462 A

  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, medals used in gaming machines are generally plated with silver or gold and are regularly cleaned (polished). Therefore, in image processing using an image sensor or a camera, it is difficult to capture an accurate image due to the irregular reflection.

  The purpose of the present invention is to prevent irregular reflection by irradiating light in an encircling manner in order to accurately detect fraudulent acts that cause a misunderstanding that a regular gaming medium is used in the gaming machine. It is an object of the present invention to provide a gaming machine that can provide a light source for capturing a highly accurate image of a gaming medium.

The light source is a gaming machine arranged at the open end.

  According to the first aspect, by performing drive control of the light source according to the imaging timing, it is possible to acquire passing object image data by the imaging unit by the irradiation light by the introduction light, and smoothly perform the determination process by the medium determination unit. Can do. Moreover, the light guide has at least one open end and an irradiation surface that surrounds the image pickup area by the image pickup means, and the light source is arranged at the open end. It is possible to uniformly irradiate the introduction light so as to surround it. Therefore, it is possible to realize a gaming machine that can surely capture the pattern, color, and the like of edges, contours, and engravings of game media and that can perform highly accurate determination processing based on accurate imaging data. That is, since uniform irradiation 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 primary reflection halation. Therefore, it is possible to realize a gaming machine capable of performing a highly accurate determination process, particularly a process for determining the marking or outline of a game medium.

  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.

Then, the sub plate 205 is rotated around the shaft portion 222 (see FIG. 8) against the urging force of the coil spring 223 to expose the medal rail 210 and remove the jammed medal. Clogging can be eliminated.

  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. 10 is a perspective view of the select plate 207 of the medal selector 201.
As shown in FIG. 10, the select plate 207 is disposed on the rear surface 204 b (see FIG. 8) side of the base plate portion 204 and is 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. 11 is a diagram showing a medal path when the medal selector 201 guides the medal to the hopper device.
In the state shown in FIG. 11, 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 the direction away from the medal rail 210 (Y direction in FIG. 11), 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. 12 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. 12, the select plate 207 is disposed at the discharge position, the protruding portion 227 a of the medal stopper portion 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 a direction away from the medal rail 210 (Y direction in FIG. 12), falls downward before reaching the medal outlet portion 204c, and pays 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. 13 is an exploded view of the camera unit 209 attached to the medal selector 201. In FIG. 13, the illustration of the cancel shooter 206 (see FIG. 8) and a wiring board 288 (see FIG. 14) 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 221a of the sub plate 205 is disposed, and is fixed by screwing to the cancel shooter 206, and the acrylic resin mounting unit 296 and the lens. A unit 287, a lens protective cover 295, a lens holder 275, an acrylic resin protective cover sheet 297, and a wiring board 288 (see FIG. 14) are provided.

  The acrylic resin mounting unit 296 is fixed to the intermediate member 293 (see FIG. 8) of the cancel shooter 206 in a state where the acrylic resin plate is sandwiched and fixed. The lens unit 287 is provided with lenses 283 to 285 (see FIG. 14), which will be described later, arranged so that the optical axis is directed toward the medal rail 210. The lens protection cover 295 is fixed to the acrylic resin mounting unit 296 and formed in a shape surrounding the lens unit 287. The lens holder 275 is fixed to the lens protection cover 295 and supports the lens unit 287. 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, a CMOS image sensor 232 (see FIG. 26), which will be described later, and a control LSI 234 (communicable with the CMOS image sensor 232) and a control LSI 234 (controllable) connected to the wiring board 288 (see FIG. 14) of the camera unit 209. 26). The CMOS image sensor 232 (see FIG. 26) images a medal moving 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.

The camera unit 209 will be described in detail.
FIG. 14 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. 14, 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. 26 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 has a tapered portion (inclined portion) 282 formed 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. 13, 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 condensing lenses (lenses 283 to 285) in a multilayer shape in front of the CMOS image sensor 232 (see FIG. 26). 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.

  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 (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. 15 shows the result of an environmental test performed at a temperature higher than room temperature (50 ° C., 60 ° C., 70 ° C.) on a lens holder 275 molded at various GF blending ratios (6 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. 15, it is preferable to add GF to 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. 16 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. 27), which will be described later, and a color determination processing means (second determination means) by a color recognition circuit 247 (see FIG. 27) 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. 27), 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. 17 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 a 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 to temporarily fix the lens body (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, the small diameter portion outer periphery of the lens unit 287 and the tapered portion 282 of the lens holder 275 are formed. 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. 26) and the condensing 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. 13 and the like). The camera unit 209 includes a CMOS image sensor 232 (see FIG. 26) 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. 14, 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 the present embodiment, paying attention to the use of LED light that does not contain an IR component (see FIG. 20) as a light source, the camera unit 209 provides a space without 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.

In FIG. 11, the alternate long and short dash line indicates the position of the lens unit 287 of the camera unit 209, and the alternate long and two short dashes line indicates the first light guide 261, the second light guide 262, and the third light guide 263. The position of LED233La, LED233Lb, and LED233Lc is shown.
As shown in FIG. 11, the first light guide 261, the second light guide 262, and the third light guide 263 are arranged so as to surround the imageable range of the camera unit 209.

  (18A) in FIG. 18 shows the appearance of the first light guide 261, and (18B) shows the appearance of the second light guide 262. In FIG. 18, the center of the formation location of the reflection grooves 267 and 270 is indicated by a broken line. FIG. 19 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. 11) from the end portion 265a on the curved portion 265 side is introduced into the end portion 266 on the linear 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. 13), the substantially L-shaped outer surface 261 a 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. 11) 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. 19, 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. 20 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. 13) with screws, the first light guide 261 is 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. 13, the mounting member 273 is fixed to the inside of the intermediate member 293 (see FIG. 8) of the cancel shooter 206 with a screw via an acrylic resin mounting plate 298, thereby the second light guide 262. As shown by a two-dot chain line in FIG. 11, the outer surface 262a exposed from the mounting member 273 is arranged in a slanting manner downward along the medal passage direction toward the curved portion 265, 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. 19 in the longitudinal direction of the mounting member 274 shown in (20C). As shown by a two-dot chain line in FIG. 11, the rear surface of 263a is brought into contact with the mounting member 274, and the mounting member 274 is fixed to the inside 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. 11, the medal rail 210 includes 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 204 c. An imaging region RLa (see FIG. 21) 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. 21 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. 13) is provided from the vicinity of the curved portion 265 of the first light guide 261 to the lower side of the straight 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. 22 shows an emission wavelength characteristic graph of the LEDs 233La to 233Lc used in this 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. 24 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 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).

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.

<Circuit configuration of medal selector>
Next, the circuit configuration of the medal selector 201 will be described with reference to FIG.
FIG. 26 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. 13). 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. 27 and 28. FIG.
FIG. 27 is a block diagram illustrating a circuit configuration example of the control LSI 234. FIG. 28 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. 28A, the image data of the regular medals (see FIG. 28B) is applied to one side of the regular medals in the area. The place (area surrounded by a dotted line in FIG. 28B) 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. 28A is shown in FIG. 28C.

  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. 29, the control LSI 234 performs processing for determining whether or not the object moving on the medal rail 210 (see FIG. 11) is a regular medal (hereinafter referred to as “regular medal discrimination processing”). Will be described).

  FIG. 29 is a diagram for explaining the regular medal discrimination process of the control LSI 234. FIG. 29 shows the relationship of processing in each device constituting the control LSI 234 in time series. A 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. 29 shows a regular medal discrimination process in the case where six medals are continuously inserted into the medal 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. 11) and outputs the image data to the control LSI 234, the ISP circuit 245 causes 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. 12, the select plate 207 is positioned at the “discharge position”, and the medal inserted after the credit counter reaches the maximum value is guided to the medal chute 202 (see FIG. 4) to give the medal. The coins are 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. 29, 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. 29, in the present embodiment, the preprocessing and the 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 relating to the second, third, fourth, fifth and sixth medals shown in FIG. 29 (the heads of the codes are “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. 30 is a diagram illustrating an example of an unauthorized medal, where A represents one surface of the unauthorized medal and B represents image data of the unauthorized medal. FIG. 31 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. 28A) but only with a 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. 30B and the regular medal image data count area (encircled by a dotted line in FIG. 28B). 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. 28A) and only with a stamp (pattern) applied to 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. 31B and the regular medal image data count area (encircled by a dotted line in FIG. 28B). 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 medals shown in FIG. 30C and the gradient average image data of the regular medals (see FIG. 28C) 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. 28A) 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 gradient average image data of this medal and the gradient average image data of the regular medal are obtained from the difference in diameter between the medal and the regular medal (see FIG. 28C). 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. 28A) 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 the present embodiment, as shown in FIG. 29, after the VSYNC interrupt signal (4IH) related to the fourth medal is output from the ISP circuit 245 to the main control circuit 91, the VSYNC interrupt related to the fifth medal. 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. 32 shows an offset process executed by the control LSI 234. FIG. 33 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. 35), 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>
A circuit configuration of the LED driving unit 252 will be described with reference to FIGS. 34 and 35. FIG.
FIG. 34 is a block diagram showing the overall configuration of the LED drive unit 252, and FIG. 35 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. 36 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 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.

[Problems to be solved by the invention]

  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, medals used in gaming machines are generally plated with silver or gold and are regularly cleaned (polished). Therefore, in image processing using an image sensor or a camera, it is difficult to capture an accurate image due to the irregular reflection.

The purpose of the present invention is to prevent irregular reflection by irradiating light in an encircling manner in order to accurately detect fraudulent acts that cause a misunderstanding that a regular gaming medium is used in the gaming machine. It is an object of the present invention to provide a gaming machine that can provide a light source for capturing a highly accurate image of a gaming medium.
[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.

  According to the first aspect of the present invention, an insertion slot (for example, a medal insertion slot 21) into which a game medium is inserted, and a game medium detection means (for example, a medal selector 201) for detecting a game medium inserted from the insertion slot. The game medium detecting means includes a passage forming part (for example, medal rail 210) that forms a path through which the game medium passes, and an imaging means (for example, imaging a passing object that is an object passing through the passage). , A CMOS image sensor 232), medium determining means (for example, control LSI 234) for determining the game medium based on the image data of the passing object imaged by the imaging means, and a guide capable of irradiating the introduced light in a planar shape. The light source (for example, the light guides 261 to 263), the light source for the introduction light (for example, the LED group 233), and the light source are driven and controlled according to the imaging timing. Drive control means (e.g., LED drive unit 252), and the light guide has at least one open end (e.g., end face 265a) and an irradiation surface (e.g., surrounding an imaging region by the imaging means). An outside surface 261a), and the light source is disposed at the open end.

  According to the first aspect, by performing drive control of the light source according to the imaging timing, it is possible to acquire passing object image data by the imaging unit by the irradiation light by the introduction light, and smoothly perform the determination process by the medium determination unit. Can do. Moreover, the light guide has at least one open end and an irradiation surface that surrounds the image pickup area by the image pickup means, and the light source is arranged at the open end. It is possible to uniformly irradiate the introduction light so as to surround it. Therefore, it is possible to realize a gaming machine that can surely capture the pattern, color, and the like of edges, contours, and engravings of game media and that can perform highly accurate determination processing based on accurate imaging data. That is, since uniform irradiation 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 primary reflection halation. Therefore, it is possible to realize a gaming machine capable of performing a highly accurate determination process, particularly a process for determining the marking or outline of a game medium.

  According to a second aspect of the present invention, the light guide is composed of a plurality of light guides each having an open end, and the light source is disposed at each open end of the plurality of light guides. It is a gaming machine characterized by this.

[Problems to be solved by the invention]

  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).

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 image sensor rapidly increases as the temperature rises, the reference black level of the captured image is shifted to cause a problem of deterioration in color reproducibility and image quality deterioration. In this embodiment, in view of such a problem, the temperature of the image sensor is detected and monitored by the temperature sensor, and when the temperature detected by the temperature sensor exceeds a predetermined threshold temperature by the offset correction unit, Since offset correction is performed, it is possible to acquire high-quality image data by maintaining the reference black level properly even if the ambient temperature changes suddenly, and the determination process can be performed with high accuracy regardless of variations in the ambient temperature. It can be carried out.

According to the second aspect, by reliably performing the offset correction with a linear interpolation value to the reference black level, it becomes possible to always obtain stable passing object image data without being affected by temperature changes. The determination process can be performed with high accuracy.
[Effect of the invention]

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.

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.
