Description

  The present invention relates to a gaming machine.

  For example, a gaming machine such as a pachinko gaming machine is provided with a game board, and a game ball is launched to the game area configured in the game board, and the game ball is awarded to various winning holes in the game area. Accordingly, a predetermined number of game balls are paid out. Further, for example, a symbol display unit made up of a liquid crystal display device or the like is installed at the center of the game area, and a plurality of columns of symbols are variably displayed by the symbol display unit. In this case, the symbol display by the symbol display unit is started with the winning of the predetermined winning opening as a trigger, and thereafter the symbol variation display is stopped through the variation display by the predetermined variation pattern. And, when the stop symbol of each symbol row is stopped, if the symbol is a predetermined symbol such as the same symbol, the special game state (big hit state) etc. is transferred and a privilege such as paying out a large amount of game balls is given. Is granted.

  In addition, recent pachinko machines are known in which a plurality of openings are provided in the game area of the game board, and a light emitter substrate is disposed on the back of the game board so that the light emitters are positioned in these openings ( For example, see Patent Document 1). In this case, the decoration of the game board surface is enhanced by lighting or blinking the light emitter at the position where the opening is provided. And the uniqueness as a pachinko machine is given by improving the decorativeness of the game board surface, and further differentiation from other models is achieved.

  However, as described above, it is necessary to dispose a symbol display unit and various winning holes on the surface of the game board, and it is necessary to dispose a plurality of nails and the like. Therefore, in the configuration in which the light emitter is disposed as described above, there is a problem in that the region in which the light emitter is disposed is restricted, and the degree of freedom in designing the region in which the light is rendered is low.

The above problems are not limited to pachinko machines provided with a symbol display unit. For example, the game board has a variable winning device having a pair of movable pieces at the ball entrance, and the advantage is provided in the variable winning device. The same applies to a pachinko machine that generates a big hit when a game ball enters the mouth (V zone).

It demonstrates as an area | region remove | excluding. That is, since the game area does not include the ball guide passage portion, the left limit position toward the game area is specified by the inner rail portion 51 instead of the outer rail portion 52. Further, the right limit position toward the game area is specified by the inner rail portion 51, the lower limit position of the game area is specified by the lower end position of the game board unit 30 in which the out port 36 is formed, and the upper limit of the game area is determined. The position is specified by the outer rail portion 52.

  Returning to the description of FIG. 3, in the resin base 25, below the window hole 26 (game board unit 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher is attached. ing. The firing rail 61 is fixedly attached to the resin base 25 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path.

  There is a predetermined gap between the firing rail 61 and the ball guide passage, and a foul ball passage 76 is provided below the gap. Accordingly, if the game ball launched from the game ball launching device does not reach the return ball prevention member 54 and returns as a foul ball in the ball guide passage, the foul ball passes through the foul ball passage 76 to the lower plate 16. To be discharged.

  When the foul balls flow backward in the ball guide passage, most of them flow along the outer rail portion 52 and fall downward when reaching the lower end portion of the outer rail portion 52. Some rampage in the ball guide passage and jump to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 76. Thereby, all of the foul balls are reliably guided to the foul ball passage 76, and interference between the foul balls and the game balls to be fired next is suppressed.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front door frame 13 side (ball outlet leading from the most downstream portion of the upper plate 23). At this time, guide members 63 and 64 are installed on the right side and the near side of the firing base end portion of the firing rail 61, respectively, so that the game balls supplied from the ball outlet on the front door frame 13 side are always predetermined. A stable launching operation can be realized.

  A pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 10) provided on the back surface of the main body frame 12, and game balls are basically discharged from the first discharge port 66. When the passage leading to the upper plate 23 including the first outlet 66 is filled with game balls, the game balls are discharged from the second outlet 67 instead of the first outlet 66.

  The game ball guide unit 70 is configured to be visible with a transparent resin material such as polycarbonate resin, and between the main body frame 12 and the front door frame 13 with the front door frame 13 closed with respect to the main body frame 12. It is formed so that the thickness is comparatively thin so that it can be accommodated. The game ball guide unit 70 is integrally formed with the foul ball passage 76 described above. The game ball guide unit 70 is formed with a ball discharge passage 71 for communicating the discharge ports 66 and 67 with the lower plate 16. In the game ball guide unit 70, a communication port 72 communicating with the upper plate 23 is formed on the front side of the first discharge port 66 of the main body frame 12, and an opening / closing plate 73 is attached so as to close the communication port 72. ing. The opening / closing plate 73 is rotatably supported by a support shaft 74 and is always urged to a position where the communication port 72 is closed by a spring 75 as urging means.

  According to the above configuration of the game ball guide unit 70, the open / close plate 73 rises as shown in the figure by the urging force of the spring 75 when the front door frame 13 is opened, and the communication port 72 is closed. In this state, the game ball discharged from the first discharge port 66 is guided to the lower plate 16 through the ball discharge passage 71. Therefore, when the front door frame 13 is opened in a state where game balls are stored upstream of the communication port 72, the stored balls flow down to the lower plate 16 through the ball discharge passage 71 without spilling from the communication port 72. To do. In other words, even in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 23 is directly provided on the front door frame 13, the game on the upstream side of the communication port 72 when the front door frame 13 is opened. The inconvenience of spilling a ball can be prevented. On the other hand, when the front door frame 13 is closed, the opening / closing plate 73 is pushed open against the biasing force of the spring 75 by a ball passage rod 138 (see FIG. 2) provided on the back surface of the front door frame 13. . In this state, the game ball discharged from the first discharge port 66 is guided to the upper plate 23 through the communication port 72. Accordingly, the game ball upstream of the communication port 72 is paid out to the upper plate 23. A lower plate full tank switch for detecting that the game ball discharged to the lower plate 16 is full (full tank) is attached to the downstream side of the ball discharge passage 71 of the game ball guide unit 70.

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. The small window 79 is provided in the position corresponding to the relay terminal hole 59 of the game board unit 30 described with reference to FIG. The connection connector 60 of the relay terminal plate is exposed on the front side of the main body frame 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is closed with respect to the main body frame 12, the pin is pushed in and the front door frame 13 is closed. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 5) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 12 side for grounding. Therefore, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

  A pair of upper and lower support brackets 81 and 82 are attached to the left end side (opening / closing axis line side) of the main body frame 12 as a support mechanism for supporting the front door frame 13 so that it can be opened and closed. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side, and the lower support fitting 82 is provided with a protruding shaft 84 protruding upward. The specific configuration of the front door frame 13 supported by the support fittings 81 and 82 will be described later. Further, a pair of upper and lower metal fittings 155 and 156 (see FIG. 2) provided on the open end side on the back side of the front door frame 13 is inserted into the right end side (the side opposite to the opening / closing axis) of the main body frame 12. Insertion holes 87 and 88 are provided, respectively. The pachinko machine 10 is configured such that a locking device for locking the main body frame 12 and the front door frame 13 is hidden behind the main body frame 12. Therefore, the front door frame 13 is locked to the main body frame 12 so that it cannot be opened by locking the metal fittings 155 and 156 to the locking device via the insertion holes 87 and 88.

  A cylinder lock 91 as a key member for locking and unlocking the main frame 12 with respect to the outer frame 11 and locking and unlocking the front door frame 13 with respect to the main frame 12 is installed at the lower right corner of the main frame 12. Has been. The cylinder lock 91 is integrated with the locking device, and only the cylinder lock 91 of the locking device is provided in a state of protruding in front of the main body frame 12. In this case, the cylinder lock 91 is provided at a position different from the position that is the maximum width of the game area. The cylinder lock 91 has a function to cover both the locking and unlocking of the main body frame 12 and the locking and unlocking of the front door frame 13, and when the key inserted into the key hole is turned counterclockwise (counterclockwise direction) When the key is unlocked and the key is turned to the right (clockwise direction), the front door frame 13 is unlocked.

  As shown in FIG. 2, a vertically long cover member 92 is attached to the main body frame 12 so as to surround the cylinder lock 91. Although detailed illustration is omitted, the cover member 92 has locking portions (hooks) formed at the upper end portion and the lower end portion thereof. Therefore, the cover member 92 is attached to the main body frame 12 by locking the upper locking portion to the main body frame 12 side and sandwiching the lower locking portion between the main body frame 12 and the front plate 14. . The front door frame 13 is formed with a notch 145 corresponding to the shape of the cover member 92. When the front door frame 13 is closed, the cover member 92 together with the front door frame 13 constitutes the front portion of the pachinko machine. . When the front door frame 13 is closed, the flange formed on the cover member 92 is pressed by the front door frame 13 to prevent the cover member 92 from rattling.

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 5 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape that is nearly circular, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape. The frame width dimension in the present embodiment is substantially the same as the distance between the uppermost portion of the outer rail portion 52 (the upper end of the game area) and the upper end of the main body frame 12 in the main body frame 12. Thereby, the visibility of the upper area in the game area can be easily ensured, and the large variable display unit 35 can also be arranged relatively upward.

  The left and right frame portions of the front door frame 13 are restricted in reducing the frame width, and need a sufficient width dimension to ensure the strength of the front door frame 13 itself and the glass support strength. In this case, in a state where the front door frame 13 is closed, a part of the spherical guide passage overlaps and is covered with the left frame portion of the front door frame 13. However, even if it becomes difficult to visually recognize the game ball in the ball guide passage, the ball guide passage is only a passing area until the game ball is guided to the game area, and the game where the player mainly enjoys the game. The game ball is not difficult to see in the area. Therefore, there is no trouble in actual game. As described above, it is possible to expand the game area without causing any trouble to the game, while ensuring sufficient strength and glass support strength of the front door frame 13.

  The front door frame 13 is provided with light emitting means such as various lamps around the periphery (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, an annular illumination part 102 incorporating light emitting means such as LEDs is provided symmetrically along the periphery of the window part 101, and an LED or the like is provided at the center of the annular illumination part 102 and at the top of the pachinko machine 10. There is provided a central illumination unit 103 incorporating the light emitting means. In the pachinko machine 10, the central lighting unit 103 functions as a jackpot lamp and notifies that the jackpot is being hit by performing lighting or blinking in the jackpot state. Further, around the upper plate 23, there is also provided an upper plate illumination unit 104 that also incorporates light emitting means such as LEDs. In addition, on the left and right sides of the central illumination unit 103, there are respectively provided a prize ball lamp 105 that is lit during award ball payout and an error display lamp 106 that is lit when a predetermined error occurs. The annular illumination part 102 includes an inner and outer double resin cover layer and a light emitting body (LED) with a launch plate accommodated inside the resin cover layer, and intersects the inner side surface of each resin cover layer vertically and horizontally in each layer. A protrusion (or a wavy protrusion) is provided in the direction of the protrusion. The outer resin cover layer is transparent, and the inner resin cover layer is colored. Therefore, if the annular illumination part 102 is caused to emit light, it is possible to realize the illumination in a state of being dispersed in a large number or in a state accompanied with a stereoscopic effect. A resin material containing glass powder may be used for the resin cover layer. Such a configuration of the resin cover layer can also be applied to other electric decoration parts (for example, the central electric decoration part 103 and the prize ball lamp 105).

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and confirmation of the card frequency can be performed by the ball lending operation unit 120 in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 10. it can. That is, the ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is paid out as long as the remaining amount exists on the card or the like. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. In addition, in a pachinko machine (so-called cash machine) in which game balls are rented directly from a ball lending device or the like to a top plate without using a card unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is attached to 120 installation portions. Thereby, in the configuration of the present pachinko machine 10 provided with the lending operation unit 120, the pachinko machine using a card unit (so-called CR machine) and the cash machine can be shared.

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcing plates 131, 132, 133, and 134 are attached to the back side of the front door frame 13 and on the left and right and upper and lower outer sides of the window portion 101, respectively. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thereby, the closed loop of the electric path by the reinforcing plates 131 to 134 is cut, and the generation of a magnetic field causing noise is prevented.

  Assembling mechanisms for the main body frame 12 are attached to the upper and lower ends of the opening / closing axis side reinforcing plate 131 on the right side of FIG. Then, the mounting brackets 151 and 152 on the front door frame 13 side are attached to the support brackets 81 and 82 (see FIG. 3) on the main body frame 12 side. That is, a shaft hole that opens to the lower surface is formed in the lower mounting bracket 152, and the protruding shaft 84 of the lower support bracket 82 is inserted into the shaft hole, while the upper mounting bracket 151 By inserting the shaft portion into the support hole 83 of the upper support fitting 81, the front door frame 13 is supported to be openable and closable with respect to the main body frame 12. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof, and the engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, even in the pachinko machine 10 in which the front door frame 13 is configured in a form including the upper plate 23 and the upper and lower shaft support intervals thereof are increased, the front door frame 13 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front door frame 13 is suppressed.

  A pair of upper and lower hook metal fittings 155 and 156 having a hook shape are attached to the reinforcing plate 132 opposite to the opening / closing axis line on the left side of FIG. These metal fittings 155 and 156 extend rearward and are provided so as to correspond to the insertion holes 87 and 88 (see FIG. 3) provided in the main body frame 12. When the front door frame 13 is closed with respect to the main body frame 12, the metal fittings 155 and 156 are inserted into the insertion holes 87 and 88 on the main body frame 12 side and are locked by the locking device.

  A resin case 136 is attached to the lower reinforcing plate 134 at a position facing the firing rail 61. The resin case 136 accommodates a circuit board for the ball rental operation unit 120. The back surface of the resin case 136 (the surface visible in FIG. 5) is flat, and constitutes the side wall of the firing rail 61 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 61.

  A ball passage rod 138 is installed at a part of the lower reinforcing plate 134 cut out toward the back of the pachinko machine 10, and at least above the ball passage rod 138, the pachinko machine 10 is also behind the pachinko machine 10. An eaves portion 139 extending toward the surface is provided. In this case, in a state where the front door frame 13 is closed on the main body frame 12 side, a ridge extending along the upper side of the communication port 72 on the main body frame 12 side enters between the ball passage rod 138 and the collar portion 139. Arranged. Therefore, even if a wire, a film, or the like is invaded from the ball passage rod 138 to perform an illegal act, it is very difficult to infiltrate the wire, the film, or the like to the game area. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and the inside of these reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows on the front and rear sides, and a pair of front and rear glasses 137 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

  As described above, in the pachinko machine 10 according to the present embodiment, the game area is expanded. Therefore, when the front door frame 13 is closed, the ball guide formed between the inner and outer rail portions 51 and 52 is used. A part of the passage is covered with the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of getting caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers a section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137. A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

  Further, on the lower back side of the rail cover 140, a ridge 142 that extends in an arc shape along the inner edge and protrudes rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 13 is closed. Therefore, for example, even if a wire or a film is intruded through a gap between the front door frame 13 and the main body frame 12 to carry out an illegal act, the wire or the film is intruded into a game area inside the ball guide passage. Becomes very difficult. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented. The ridge 142 may be formed in a wider range, for example, along the entire inner edge of the rail cover 140. According to such a configuration, it becomes difficult for a wire, a film, or the like to enter in a wider range, It is possible to more reliably prevent fraudulent acts performed using a wire, a film, or the like.

  Next, the configuration of the back surface of the pachinko machine 10 will be described. 6 is a rear view of the pachinko machine 10, and FIG. 7 is an exploded perspective view showing the rear structure of the pachinko machine 10 for each main part.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. On the back side of the pachinko machine 10, various control devices (various control boards) are arranged so as to be arranged in the vertical and horizontal directions or stacked in front and back, and a game ball supply device for supplying game balls (Discharge mechanism), a protective cover made of resin, and the like are attached. In the present embodiment, the various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually mounted on the back surface of the main body frame 12 or the game board unit 30. I have to. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. The apparatus 312 (launch control board) and the power supply apparatus 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units, and are provided with a support shaft part in a part to form the main body frame 12. Or it has the composition which can be developed to the back of game board unit 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 8, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Yes. Further, the back pack unit 203 is disposed in a region partially overlapping with the first control board unit 201.

  The first control board unit 201 is provided with a support shaft part M1 at the left end portion when viewed from the back of the pachinko machine 10, and the first control board unit 201 can be rotated around an axis A by the support shaft part M1. ing. Further, the first control board unit 201 is provided with a fastening portion M2 made of Nylatch (registered trademark) on the right end portion thereof, that is, on the open end side opposite to the support shaft portion M1, and with a locking claw at the upper end portion. A portion M3 is provided, and the first control board unit 201 is held along the back surface of the main body of the pachinko machine 10 by the fastening portion M2 and the locking claw portion M3. Further, the second control board unit 202 is provided with a support shaft part M4 at the right end when viewed from the back of the pachinko machine 10, and the second control board unit 202 can be rotated around the axis B by the support shaft part M4. It has become. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like on the left end portion thereof, that is, on the open end side opposite to the support shaft portion M4. The substrate unit 202 is held in a state along the back surface of the pachinko machine 10 main body. Further, the back pack unit 203 is provided with a support shaft part M6 at the right end when viewed from the back of the pachinko machine 10, and the back pack unit 203 is rotatable about an axis C by the support shaft part M6. . Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like on the left end portion thereof, that is, on the open end side opposite to the support shaft portion M6, and at the upper end portion and the lower end portion, respectively, a rotating engagement member. Stop portions M8 and M9 are provided, and the back pack unit 203 is held along the back surface of the pachinko machine 10 main body by the fastening portions M7 and the locking portions M8 and M9.

  The support shaft portions M1, M4, and M6 that rotatably support the units 201 to 203 have a hinge structure that can be easily detached while the units 201 to 203 are opened from the back surface of the pachinko machine 10. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3 and rotating the unit 201 around the axis A, Lift in condition. Thereby, if there is no back pack unit 203, the first control board unit 201 can be removed. Further, with respect to the second control board unit 202, the fastening of the fastening portion M5 is released, the unit 202 is rotated about the axis B, is unfolded, and is lifted in that state. Thereby, the 2nd control board unit 202 can be removed. Further, with respect to the back pack unit 203, the fastening portion M7 and the locking portions M8 and M9 are unlocked, and the unit 203 is unfolded by rotating around the axis C and lifted in that state. Thereby, the back pack unit 203 can be removed.

  Here, the development directions of the units 201 to 203 are not the same, and the first control board unit 201 opens to the left as viewed from the back of the pachinko machine 10, whereas the second control board unit 202 and the back pack unit. 203 is configured to open to the right. In this case, since the first control board unit 201 is partially overlapped with the back pack unit 203, it is impossible to remove the first control board unit 201 without opening the back pack unit 203. Furthermore, since the first control board unit 201 and the back pack unit 203 are each configured to expand in the opposite direction, the back pack unit 203 must be opened largely beyond a predetermined angle or removed. For example, the first control board unit 201 cannot be removed. Accordingly, when attention is paid to removing the first control board unit 201, the removal is difficult compared to the other units 202 and 203. Furthermore, since the back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation of the locking device, the first control board unit 201 is further removed. Has become difficult. A more specific configuration will be described later.

The box base and the box cover are connected to each other so as not to be opened by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

  As long as the sealing unit 274 is configured to connect the box base and the box cover so that they cannot be opened, any configuration can be applied. Here, as shown in FIG. 14 and the like, five sealing members are connected. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit 274 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 274. When the substrate box 273 is opened, such as when a failure occurs in the accommodated main substrate or when the main substrate is inspected, the connection between the sealing member into which the locking claw is inserted and the other sealing member is disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 273 is left in the substrate box 273, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 273.

  The sound lamp control device 272 includes a CPU for controlling sound and lamp display according to an instruction from the main control device 271 or the display control device 214, and a sound lamp control board including other ROM, RAM, various ports, and the like.

  Next, the configuration of the game board unit 30 which is a characteristic part of the present embodiment will be described. As shown in FIG. 23, the game board unit 30 includes a game area plate 160 located on the front surface, three light guide plates 171, 172, and 173 disposed on the back side of the game area plate 160, and a light guide plate 171. , 172, and 172 are provided as main components. The game area plate 160, the light guide plates 171, 172, 173, and the mounting plate 190 have a substantially rectangular shape with substantially the same thickness, size, and outer shape, and are fixed so that their opposing surfaces are substantially in contact with each other. Has been. Specifically, the screws 161 are inserted and fixed to the openings formed so as to be coaxial with the four corners of the plates 160, 171, 172, 173 and 190.

  The game area plate 160 is made of a colorless and transparent polycarbonate resin, and the game area is formed on the surface thereof by attaching the variable winning device 32, the operation port 33, the nail 39, and the like (see FIG. 23). The variable winning device 32, the operation port 33, the nail 39, etc. are omitted). Here, since the polycarbonate resin has a relatively high elasticity, the game area plate 160 is formed of the polycarbonate resin, so that even if the game ball collides with the nail 39 or the like driven into the surface, the game area plate 160. The structure is less likely to crack. It should be noted that the length of the screw for arranging the variable winning device 32 and the operation port 33 in the game area plate 160 and the length of the nail 39 driven into the game area plate 160 are based on the thickness of the game area plate 160. These screws and nails 39 do not reach the light guide plate 171 on the near side.

  Next, the structure of the light guide plates 171, 172, 173 will be described with reference to FIGS. FIG. 24 is a front view of each light guide plate 171, 172, 173. 25 and 26 are enlarged views for explaining the lower end portion of the game board unit 30, FIG. 25 (a) is a partially broken front view of the game board unit 30, and FIG. 25 (b) is the game board unit. FIG. 26A is a plan view of the element substrate 180 disposed on the light guide plates 171, 172, and 173, and FIG. 26B is a bottom (bottom) view of the game board unit 30. FIG. 27 is an explanatory diagram for explaining a light path in the light guide plates 171, 172, and 173. In the following description, the light guide plate 171 located on the near side is the first light guide plate 171, the light guide plate 172 located between the second light guide plate 172 and the light guide plate 173 located on the far side is the third light guide plate 173. Also called.

  Each light guide plate 171, 172, 173 is made of a colorless and transparent acrylic resin. Each light guide plate 171, 172, 173 has a plurality of through holes 171a, 172a, 173a corresponding to the through holes formed in the game area plate 160, as shown in FIG. The game balls that have been launched at 160 and entered the general winning port 31, the variable winning device 32, and the operating port 33 are guided to the inside of the gaming machine through these through holes 171a, 172a, and 173a.

  At the lower end of each light guide plate 171, 172, 173, a plurality of recesses 171c, 172c, 173c that are recessed inward (upward) and penetrated in the thickness direction (front-rear) are formed. However, the lower end of each light guide plate 171, 172, 173 as a whole extends straight in the left-right direction. The element substrate is arranged such that light emitting diodes 181, 182, and 183 (hereinafter referred to as LEDs) for introducing light into the light guide plates 171, 172, and 173 are positioned in the recesses 171 c, 172 c, and 173 c. 180 is disposed (see the broken portion in FIG. 25A). Specifically, the element substrate 180 is fixed to the lower surfaces of the light guide plates 171, 172, and 173 by a fixing tool such as a screw. The recesses 171c, 172c, and 173c are formed along the outer shape of the LEDs 181, 182, and 183.

  The LEDs 181, 182, and 183 disposed on the element substrate 180 have three types of emission colors of blue, red, and green. The blue LED 181 is disposed in the recess 171 c of the first light guide plate 171, and the second light guide plate The red LED 182 is located in the concave portion 172 c of 172, and the green LED 183 is located in the concave portion 173 c of the third light guide plate 173. However, in order to prevent the LEDs 181, 182, and 183 from being arranged in a row in the width direction of the element substrate 180 (the thickness direction of the light guide plates 171, 172, and 173), as shown in FIG. The red LED 182 is displaced from the arrangement position of the LED 183. Accordingly, as shown in FIG. 26B, the LEDs 181, 182, and 183 are positioned every other recesses 171 c, 172 c, and 173 c formed in the light guide plates 171, 172, and 173. It has a configuration. In addition, the thickness of each light guide plate 171,172,173 is comparable to the length of LED181,182,183 in the front-back direction (the thickness direction of each light guide plate 171,172,173).

  On the back surface of the element substrate 180, as indicated by broken lines in FIG. 26A, a plurality of resistors 184, 185, 186 for adjusting the currents flowing through the various LEDs 181, 182, 183 are provided. Are arranged in a row. These resistors 184, 185, and 186 are provided at a ratio of one to three LEDs in the various LEDs 181, 182, and 183. Three LEDs and one resistor are connected in series, and a group of these groups is connected in parallel.

  When the light of the LEDs 181, 182, 183 is introduced into the light guide plates 171, 172, 173, the light basically repeats total reflection within the light guide plates 171, 172, 173. Specifically, as shown in FIG. 27, the introduced light basically travels along a path such as L1, and has an incident angle larger than the critical angle with respect to the normal of the outer surface of the light guide plates 171, 172, and 173. By entering the outer surfaces of the light guide plates 171, 172, 173, the total reflection is repeated and proceeds. In this case, a light reflecting tape 175 is attached to the lower end of each light guide plate 171, 172, 173 so as to cover the recesses 171c, 172c, 173c penetrating in the thickness direction (FIG. 25 (b) and FIG. 26 (b)). Thereby, it is suppressed that the light of each LED181,182,183 is introduce | transduced into the light guide plates 171,172,173 which do not respond | correspond, ie, the light guide plates 171,172,173 located adjacent.

  On the back surface of each light guide plate 171, 172, 173, fine linear irregularities (uneven portions 171b, 172b, 173b) are formed by mechanical etching, and the uneven portions 171b, 172b, 173b are formed. Due to the presence, patterns are represented as shown in FIGS. In each light guide plate 171, 172, 173, the uneven portions 171b, 172b, 173b are arranged so as not to overlap in the front-rear direction. Accordingly, as shown by the path L2 in FIG. 27, as a result of repeating total reflection in each of the light guide plates 171, 172, 173, the light directed toward the uneven portions 171b, 172b, 173b is reflected by the uneven portions 171b, 172b, When the incident angle is changed at 173b, diffuse reflection is performed, and a part of the light is emitted from the surface side. The emitted light is such that the game area plate 160 and the light guide plates 171, 172, 173 are colorless and transparent, and the positions of the concavo-convex portions 171b, 172b, 173b in the light guide plates 171, 172, 173 are shifted. Continue to the front of the machine without being blocked. When this light is observed from the front of the gaming machine, the patterns of the concave and convex portions 171b, 172b, 173b of the light guide plates 171, 172, 173 appear to shine with the emission colors of the corresponding LEDs 181, 182, 183. In FIG. 27, for convenience of explanation, the dimensions of the uneven portions 171b, 172b, and 173b with respect to the thickness of the light guide plates 171, 172, and 173 are shown larger than the actual dimensions.

  The light emitted from each light guide plate 171, 172, and 173 is visually recognized from the front of the gaming machine, but the blue LED 181 and The resistance values of the resistors 184 and 186 provided in the green LED 183 are set lower than the resistance value of the resistor 185 provided in the red LED 182. That is, since the blue LED 181 has a smaller amount of light per unit current than the red LED 182 and the green LED 183, the amount of light is increased by providing a resistor having a low resistance value and increasing the current flowing through the blue LED 181. Further, since the green LED 183 is provided on the third light guide plate 173, the light emitted from the third light guide plate 173 is transmitted through the second light guide plate 172 and the first light guide plate 171. The perceived brightness will be dark. Therefore, by setting a resistance having a resistance value lower than that of the red LED 182 and increasing the current flowing through the green LED 183, the amount of light is increased, and the brightness viewed from the front of the pachinko machine 10 is set to be about the same as red. Yes.

  A plurality of through-holes 171a, 172a, 173a formed in each of the light guide plates 171, 172, 173 are covered with a light reflecting tape 176 (see a partially enlarged view of FIG. 24C). The peripheral surfaces of the light guide plates 171, 172, and 173 that are not provided with the element substrate 180 are also covered with the light reflecting tape 177. Thereby, even if the light totally reflected in the light guide plates 171, 172, and 173 reaches the peripheral wall portions of the through holes 171 a, 172 a, and 173 a and the peripheral surfaces of the light guide plates 171, 172, and 173, the light leaks to the outside. The light is reflected by the light reflecting tapes 176 and 177. Therefore, as shown by the paths L3 and L4 in FIG. 27, the reflected light travels while being totally reflected, and is emitted to the outside by reaching the concave and convex portions 171b, 172b, and 173b. For example, if the light reflecting tapes 176, 177 are not provided, light leaks outside at the peripheral wall portions of the through holes 171a, 172a, 173a and the peripheral surfaces of the light guide plates 171, 172, 173a, and the uneven portions 171b, 172b, 173b. This reduces the amount of light reflected.

  The mounting plate 190 is made of wood, and a cell printed with a pattern or the like is attached to the surface thereof. Further, the above-described aggregate plate unit 215 and the like are attached to the back surface. The mounting plate 190 also has a plurality of through holes corresponding to the through holes formed in the game area plate 160, and the game balls that have entered the general winning port 31, the variable winning device 32, and the operating port 33 are It is led into the gaming machine through the through hole.

  The through holes of the game area plate 160, the light guide plates 171, 172, and 173 and the mounting plate 190 are individually formed for each plate, and then fixed by screws 161 as described above. In this case, since the through hole formation position is less likely to be displaced than in the configuration in which the through holes are formed after the plates 160, 171, 172, 173, and 190 are fixed with the screws 161, the accuracy of the through hole formation position is improved. It has been.

It is. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SG2 to the main controller 271 and the payout controller 311. Thereby, when the power of the pachinko machine 10 is turned on while the RAM erase switch 323 is pressed, the data in the respective backup areas 503a and 513a is cleared in the main controller 271 and the payout controller 311.

  Next, the configuration of the audio lamp control device 272 will be described with reference to FIG.

  As shown in FIG. 29, the sound lamp control device 272 includes a CPU 551, a program ROM 552, a work RAM 553, and an input port 556. Further, although not shown, a timer circuit such as a light emission period measuring timer for measuring the light emission periods of the LEDs 181, 182, and 183, various counters such as a light emission color counter, and the like are provided. The CPU 551 of the sound lamp control device 272 inputs a control command such as an effect command or an end command output from the display control device 214 via the input port 556, analyzes the control command, or performs predetermined processing based on the control command. Arithmetic processing is performed to control the LEDs 181, 182, and 183 and lamps (not shown). The program ROM 552 is a memory for storing various control programs executed by the CPU 551 and fixed value data. The work RAM 553 is a memory for temporarily storing work data and flags such as a pattern 1 setting flag used when the CPU 551 executes various programs.

  Here, the display content of the symbol display device 41 will be described with reference to FIG.

  In the symbol display device, three symbol columns of left, middle, and right are set. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-symbol made of, for example, a diamond-shaped picture. Each main symbol and sub-design constitute a first symbol. In each symbol row, main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. That is, each symbol row is provided with a total of 20 first symbols of 10 main symbols and 10 sub symbols. In this case, the main symbols with odd numbers (1, 3, 5, 7, 9) correspond to “high probability symbols”, and when the high probability symbols are aligned, the big game state that is a special gaming state is entered. After that, the state shifts to a state with a high probability. The main symbols with even numbers (2, 4, 6, 8) correspond to “low-probability symbols”. When the low-probability symbols are aligned, the game shifts to a jackpot state. Does not transition to the time state. The high probability means a state where the combination of the first symbol is a big hit by a predetermined combination of probability fluctuation symbols and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state. Moreover, in the 1st specific lamp part 47, red is displayed at the time of the big hit which becomes a probability change state, and green is displayed at the big hit which becomes a normal state.

  On the symbol display device 41, 20 first symbols are variably displayed so as to scroll from top to bottom with periodicity for each symbol row. In particular, the numbers of the main symbols appear in descending order in the left symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the right symbol row. The symbol display device 41 is configured to display the upper, middle, and lower three first symbols for each symbol row. Therefore, the symbol display device 41 displays a total of nine first symbols of 3 rows × 3 columns. The symbol display device 41 has five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5. Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, it is a combination of jackpot symbols on any active line (in this embodiment, the same main symbol combination) If you arrange it, a big hit video will be displayed as a big hit.

  Next, the operation of the pachinko machine 10 configured as described above will be described.

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information in the game to make a big hit lottery, set the emission color of the first specific lamp unit 47, set the symbol display of the symbol display device 41, etc. Specifically, as shown in FIG. 31, the jackpot random number counter C1 used for the jackpot lottery, the jackpot type counter C2 used for determining the jackpot type, and the symbol display device 41 Reach random number counter C3 used for reach lottery when out-of-range changes, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, and first variation type counter used for variation pattern selection of symbol display device 41 CS1 and a second variation type counter CS2 that determines a period for switching the color displayed on the first specific lamp unit 47 , It is set to be used left column, the middle column and the right column the off each off symbol counters in the left-and right to use the setting symbol CL of, CM, and CR.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). The values of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are stored in time series according to the winning history.

For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is periodically (in this embodiment, 1 per timer interrupt).
Updated) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot type counter C2 is incremented by 1 within a range of 0 to 49, and reaches a maximum value (that is, 49) and then returns to 0. In the present embodiment, the jackpot type counter C2 determines whether the probability change state or the normal state is set after the jackpot is finished. For example, the jackpot that C2 = 0 to 24 becomes the probability change state. In this case, C2 = 25 to 49 corresponds to a jackpot that is in a normal state. The jackpot type counter C2 also determines the symbol combination when the symbol display device 41 stops changing and the position at which the symbol combination is stopped. That is, in the present embodiment, there are 5 effective lines in the symbol display device 41, and ten specific symbols (main symbols) are set. Therefore, all patterns are set by 50 counter values. Will be. Then, when C2 = 0 to 24, that is, when the jackpot is in a probable variation state, the combination of the odd-numbered symbols and the position at which the symbol combination is stopped are determined. On the other hand, when C2 = 25 to 49, that is, when the jackpot is a normal state, the combination of the even-numbered symbols and the position at which the symbol combination is stopped are determined. The jackpot type counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. Reach lottery may be set individually according to the state of the lottery probability of the symbol display device 41, the number of operation suspension balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  The first variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and reaches a maximum value (that is, 198) and then returns to 0. The second variation type counter CS2 includes, for example, Within the range of 0 to 240, 1 is added in order, and after reaching the maximum value (that is, 240), it returns to 0. The first variation type counter CS1 determines the display mode of the symbol display device 41, such as so-called normal reach, super reach, premium reach, etc., the first symbol reach type and other rough symbol variation modes, and the second variation type counter CS2 The switching display time is determined as a period for switching the color displayed on the first specific lamp unit 47. The switching display time corresponds to the symbol variation time of the symbol display device 41. Therefore, by the second variation type counter CS2, the elapsed time (in other words, the number of variation symbols) until the final stop symbol (in the present embodiment) stops after reaching occurs in the symbol display device 41, etc. A detailed design variation mode is also determined. That is, regarding the symbol display device 41, a variety of variation patterns can be easily realized by combining both the variation type counters CS1 and CS2. Both variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of both variation type counters CS1 and CS2 are acquired when switching the color displayed on the first specific lamp unit 47 and when determining the variation pattern at the time of starting the variation of the first symbol by the symbol display device 41.

  The left, middle and right off symbol counters CL, CM, CR determine the stop symbol of the left row 1 symbol, the middle row 1 symbol, and the right row 1 symbol when the big hit lottery is missed. In each column, any one of the 20 first symbols is displayed in combination with the main symbol and the sub symbol, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle and lower symbols are determined by the out symbol counter CL, the upper, middle and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The top, middle and bottom symbols are determined.

  In the present embodiment, the values of the counters CL, CM, and CR are randomly updated by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the value of the lower 3 bits of the R register is added to the previous value, and when the addition result exceeds the maximum value, 20 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated within the normal processing so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach of the RAM 503 front / rear out symbol buffer, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the start of variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier and the completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second specific lamp random number counter C4 is used for the lottery of the second specific lamp unit 48. The second symbol random number counter C4 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The second specific lamp counter C4 is updated periodically (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 in the main controller 271 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is broadly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and power failure to the NMI terminal (non-maskable terminal). There is NMI interrupt processing activated by signal input. For convenience of explanation, first, timer interrupt processing and NMI interrupt processing will be described, and then main processing will be described.

  FIG. 37 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 271 every 2 msec, for example.

  In FIG. 37, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 271 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in step S602, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In subsequent step S603, the big hit random number counter C1, the big hit type counter C2 and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. This start winning process will be described with reference to the flowchart of FIG. 38. In step S701, whether or not the game ball has won the start opening (start winning) is determined based on the detection information of the operation opening switch 224. When it is determined that the game ball has won the operating port 33, in the subsequent step S702, the number N of the operation reserved balls of the first specific lamp unit 47 and the symbol display device 41 is less than the upper limit value (4 in the present embodiment). It is determined whether or not there is. The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In subsequent step S704, the values of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area of the free storage areas of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

  When the game ball wins the operating opening 33 (starting winning), the display of the first symbol on the symbol display device 41 is started accordingly, but after the winning winning, the first symbol is changed and the symbol is changed. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before stopping. Therefore, in the start winning process, when a start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S704). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and the variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed). .

  FIG. 39 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program of FIG. 39 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing, in step S801, the used register is saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the power-off occurrence information is set in the backup area 503a, and in step S804, a power-off notification command indicating that the power has been cut off is transmitted to another control device. In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The above NMI interrupt processing is similarly executed in the payout control device 311, and the state of the payout control device 311 when the power is shut down due to the occurrence of a power failure or the like is stored in the backup area 513 a of the RAM 513 by the NMI interrupt. Similarly, power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 39 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 32 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 271, and this main process is started upon a reset when the power is turned on.

  In the main process, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (audio lamp control device 272, payout control device 311, etc.) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311, and in step S103, RAM access is permitted.

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, in step S104, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed, and in subsequent step S105, it is determined whether or not the information on occurrence of power shutdown is set in the backup area 503a of the RAM 503. To do. In step S106, a RAM determination value is calculated. In subsequent step S107, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. Note that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 323. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to a RAM initialization process (steps S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to the initialization process of the RAM 503 (steps S114 to S116). . That is, in step S114, the used area of the RAM 503 is cleared to 0, and in the subsequent step S115, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S108, the stack pointer before power-off is restored, and in step S109, information on occurrence of power-off is cleared. In step S110, a command for returning the sub-side control device to the gaming state at the time of power-off is transmitted, and in step S111, the used register is returned from the backup area 503a of the RAM 503. In steps S112 and S113, the interrupt permission / non-permission is returned to the state before the power shutdown, and then the address before the power shutdown is returned.

  Next, the flow of normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, the processing of steps S201 to S207 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S209 and S210 is executed with the remaining time.

  In the normal process, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. In addition, a stop symbol command, a variation pattern command, a determination command, and the like are transmitted to the display control device 214 when the symbol display device 41 displays the variation of the first symbol. In addition, after the start of the fluctuation of the first symbol, one each time in the normal process in order of the fluctuation pattern command → the left symbol row stop symbol command → the middle symbol row stop symbol command → the right symbol row stop symbol command The command is transmitted once every 4 msec), and the determination command is transmitted at the timing when the fluctuation time elapses.

  Next, in step S202, the both variation type counters CS1 and CS2 are updated. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503. In subsequent step S203, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  The update process of each outlier symbol counter CL, CM, CR will be described. As shown in FIG. 34, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. It is determined whether or not it is time to update the symbol counter CM symbol symbol CM. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both NO in steps S301 and S302), the process proceeds to step S305, and the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR. According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, in step S306, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination. If the symbol combination is a jackpot symbol combination, the process is terminated. If it is not a jackpot symbol combination, it is determined in step S307 whether or not it is a reach symbol combination, and if it is a reach symbol combination, it is further determined in step S308 whether or not it is a front-rear reach. To do. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S309, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear outreach symbol buffer of the RAM 503. When the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step S310, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. . If the combination of outlier symbol counters CL, CM, CR is not a jackpot symbol combination and not a reach symbol combination (when both steps S306 and S307 are NO), this is a combination of outlier symbol counters CL, CM, CR In this case, the process proceeds to step S 311, and the combination of the off symbol counters CL, CM, and CR at that time is stored in the complete off symbol buffer of the RAM 503.

  After the update process of the off symbol counters CL, CM, CR, in step S204 in FIG. 33, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 47 is executed. By the first specific lamp unit control process, the big hit determination, the on / off control of the light source switch of the LED lamp disposed in the first specific lamp unit 47, and the like are performed. In the first specific lamp unit control process, the symbol display device 41 also sets the variable display of the first symbol. However, details of the first specific lamp unit control process will be described later.

  Thereafter, in step S206, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 35 in the case of the big win state is executed. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, a second specific lamp unit control process for switching the color displayed on the second specific lamp unit 48 is executed. Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second specific lamp counter C4 is acquired and the color switching process displayed on the second specific lamp unit 48 is performed each time. To be implemented. Then, when the lottery of the color displayed by the value of the second specific lamp random number counter C4 is performed and red is selected, the electric accessory attached to the operation port 33 is released for a predetermined time. Although not described, the second specific ramp counter C4 is also updated by the timer interrupt process shown in FIG. 37, like the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3.

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. The random number initial value counter CINI and both variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In step S210, both variation type counters CS1 and CS2 are updated. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, by repeatedly updating the random number initial value counter CINI using the remaining time, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random. Similarly, Both variation type counters CS1 and CS2 can be updated at random.

  Next, the first specific lamp unit control process of step S205 will be described with reference to the flowcharts of FIGS.

  In the first specific lamp unit control process, in step S401, it is determined whether or not a big hit is currently being made. Note that the jackpot includes a jackpot game displayed on the symbol display device 41 when the jackpot is won and a predetermined time after the jackpot game ends. During this time, red or green continues to be displayed on the first specific lamp unit 47. In a succeeding step S402, it is determined whether or not the first specific lamp unit 47 is being switched and displayed. If the first specific lamp unit 47 is not in the switching display and the jackpot is not being hit, the process proceeds to step S403, and whether or not the number N of the operation reserved balls of the first specific lamp unit 47 and the symbol display device 41 is greater than zero. Is determined. Then, when the jackpot is being hit or the number N of operation-reserved balls is 0, the present process is terminated as it is.

  If the jackpot or the first specific lamp unit 47 is not being displayed for switching and if the number of operation-pending balls N> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of active suspension balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, a switching start process for starting switching of the color displayed on the first specific lamp unit 47 is executed. Specifically, the timer is reset in order to determine the switching time of the displayed color, and the switch of the light source currently turned on of the LED lamp disposed in the first specific lamp unit 47 is turned off. Above, the switch of the red light source is turned on. Accordingly, red is displayed on the first specific lamp unit 47. If it is not after the big hit, the blue light source is turned on before the start of the switching display, and if it is after the big hit, the red light source or the green light source is turned on. In this switching start process, the above process is performed, the value of the second variation type counter CS2 stored in the counter buffer of the RAM 503 is checked, and the second variation type counter CS2 is checked based on the value of the second variation type counter CS2. 1 The switching display time of the color displayed on the specific lamp unit 47 is determined. It should be noted that the relationship between the numerical value of the second variation type counter CS2 and the displayed switching time of the color is defined in advance by a table or the like.

  Thereafter, in step S407, the first symbol variation start process is executed. Here, the details of the variation start process will be described with reference to the flowchart of FIG. 36. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. “601, 661” is the winning value.

  If it is determined that the game is a big hit, in step S502, a symbol corresponding to the value of the big hit type counter C2 stored in the execution area of the holding ball storage area, that is, a table not showing the big hit symbol (value of the big hit type counter C2). And a symbol representing the correspondence between the symbol and the symbol), and the symbol is set as a stop symbol command. At this time, the numbers 0 to 49 of the jackpot type counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. When these jackpot symbols are gathered with a predetermined specific symbol, the state changes to a probability variation state. However, when the symbols are not specific symbols (non-specific symbols), the probability variation state is not entered.

  Next, in step S503, the variation pattern of the first symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the two variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach type such as normal reach, super reach, premium reach, etc. based on the value of the first variation type counter CS1 and others An approximate symbol variation mode is determined, and the elapsed time (in other words, the number of variation symbols) until the final stop symbol (in the present embodiment) stops after the occurrence of reach based on the value of the second variation type counter CS2. ), Etc., to determine a finer pattern variation mode. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, as described above, the switching display time of the color displayed on the first specific lamp unit 47 is determined by the value of the second variation type counter CS2. Therefore, the table that defines the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time includes the numerical value of the second variation type counter CS2 and the color switching display time displayed on the first specific lamp unit 47. It is associated with a table that defines the relationship. The same applies to the setting of the fluctuation pattern in the case of performing front / rear out of reach display, reach display other than front / rear out, and complete out of display described later.

  If it is determined in step S501 that the game is not a big hit, it is determined in step S504 whether or not reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area. In the case of the above, in step S505, it is determined whether the reach is out of front or back based on the value of the reach random number counter C3. In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 238, of which “0, 1” corresponds to the out-of-front reach and “2-21” corresponds to the reach other than the back-and-forth out- “22 to 238” corresponds to no reach (complete detachment).

  If front / rear out of reach has occurred, the process proceeds to step S506, and the left, middle, and right out of symbol counters CL, CM, and CR stored in the front / rear out of reach design buffer of the RAM 503 are set as stop symbol commands. Also, in step S507, a variation pattern for front / rear out of reach display is determined, and the variation pattern is set as a variation pattern command. At this time, as in step S503, the values of the two variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the normal reach, super reach, and premium are determined based on the value of the first variation type counter CS1. The reach type such as reach and other rough symbol variation modes are determined, and the elapsed time until the final stop symbol (medium symbol in the present embodiment) stops after the occurrence of reach based on the value of the second variation type counter CS2. (In other words, the number of variation symbols) and the like, a more detailed symbol variation mode is determined.

  If a reach other than front / rear out occurs, the process proceeds to step S508, and the left, middle, and right outreach counters CL, CM, and CR stored in the reach symbol buffer other than front / rear out of RAM 503 are set as stop symbol commands. To do. In step S509, a variation pattern for reach display other than front / rear deviation is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like.

  If it is neither big hit nor reach, the process proceeds to step S510, and the left, middle, and right off symbol counters CL, CM, and CR stored in the complete off symbol buffer of the RAM 503 are set as stop symbol commands. In step S511, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of both variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 as in step S503 and the like. As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, when the reach occurs, or when the reach does not occur, this processing is terminated.

  Returning to the description of FIG. 35, if step S402 is YES, that is, if the switching of the color displayed on the first specific lamp unit 47 is being displayed, the process proceeds to step S408 to determine whether or not the switching display time has elapsed. To do. As described above, the color switching display time displayed on the first specific lamp unit 47 is set in advance, and when this switching display time has elapsed, an affirmative determination is made in step S408. If it is determined in step S408 that the switching display time has not elapsed, display color switching processing is executed in step S409. By this display color switching process, the switch of each light source is on / off controlled, and the color displayed on the first specific lamp unit 47 is switched. Specifically, it is determined whether the timer reset in the switching start process has passed a predetermined time (for example, 1 sec). If the predetermined time has passed, the light source switch that is currently on is turned off. After the control, a preset flag is confirmed, a predetermined light source is turned on based on the flag, and a flag is set and erased. Two types of flags, such as a first flag and a second flag, are set. The light source to be turned on next is determined by the states of these two types of flags. For example, when the first flag is 0 and the second flag is 1, the switch of the green light source is turned on, and the second flag is erased (both flags are in a 0 state). When both flags are 0, the blue light source switch is turned on, and the first flag is set (the first flag is 1 and the second flag is 0). Further, when the first flag is 1 and the second flag is 0, the switch of the red light source is turned on, the first flag is erased, and the second flag is set (the first flag is 0, The second flag becomes 1). In the variation start process, the first flag is set to 0 and the second flag is set to 1 after the red light source switch is turned on. As a result, the color displayed on the first specific lamp unit 47 is changed in the order of red, green, and blue, and the switching of the colors in the order is repeated. On the other hand, if the predetermined time has not elapsed, the process is terminated without performing on / off control of the light source switch.

  If it is determined in step S408 that the switching display time has elapsed, a switching end process is executed in step S410. This switching end process is a process for determining which color will eventually stop switching the color displayed on the first specific lamp unit 47 and turning on the light source of the determined color. Specifically, first, the switch of the light source that is currently turned on is turned off. After that, the value of the jackpot random number counter C1 and the value of the jackpot type counter C2 stored in the counter buffer of the RAM 503 is confirmed. When a big hit that is in the normal state occurs in the game time, the green light source switch is turned on. When no big hit occurs in the game time, the blue light source switch is turned on. Thereby, the color according to each game result will be displayed on the 1st specific lamp part 47. FIG. Note that. The display color set here is maintained until the next switching start process. After this switching end processing is performed, in S411, a determination command set for determining the stop symbol is set, and then this processing ends.

  The stop symbol command, the fluctuation pattern command, the determination command, etc. set in the first specific lamp unit control process are output to the display controller 214 in the external output process in the normal process of FIG. Based on these commands, the display control device 214 determines detailed display contents such as a symbol variation mode and directly controls the display of the symbol display device 41. Thereby, the change display of a symbol is performed on the display screen of the symbol display device 41.

  Here, the manner of switching the color displayed on the first specific lamp unit 47 will be described below with reference to FIG. 40 in association with the symbol variation display on the symbol display device 41. FIG. 40A shows the display status of the left, middle, and right symbols of the symbol display device 41 and the status of whether or not the color switching display displayed on the first specific lamp unit 47 is being performed. Reference numeral 40 (b) shows a detailed state of the color switching control displayed on the first specific lamp unit 47. Note that FIG. 40 shows a pattern in which a jackpot that is likely to change in the current game round is generated in the previous game round, but the color displayed at the beginning and end is the other pattern. The basic aspects are the same except for the differences.

  First, at the timing of t1, the main control device 271 starts switching control of the color displayed on the first specific lamp unit 47 by performing on / off control of the switch of the LED lamp disposed in the first specific lamp unit 47. At the same time, a display command is output to the display control device 214. Then, the display control device 214 controls the display of the symbol display device 41 so as to immediately start the variable display of the left, middle and right symbols on the display screen based on the display command. As a result, the left / middle / right symbol variation and the color switching display displayed on the first specific lamp unit 47 are started simultaneously. Further, at the timing of t1, the main control device 271 determines the color switching display time displayed on the first specific lamp unit 47 based on the value of the second variation type counter CS2. This switching display time corresponds to the time from t1 to t4 in FIG. Thereafter, the display control device 214 independently controls the display of the symbol display device 41, so that the left symbol variation display is stopped at the timing t2, the right symbol variation display is stopped at a predetermined interval, and t3. At this timing, the change display of the middle symbols is stopped. During this time, the main control device 271 continues the switching control of the color displayed on the first specific lamp unit 47 by turning on and off the switches of the respective light sources of the LED lamps arranged in the first specific lamp unit 47. Is going. Specifically, the first specific lamp unit 47 displays each color for a predetermined time in the order of red, green, and blue, and the color displayed in that order is repeatedly switched. Then, at the timing of t4, the main controller 271 determines that the switching display time has elapsed, and controls to turn off the green light source switch of the LED lamp disposed in the first specific lamp unit 47, and further to the red light source By switching on this switch, the process of ending the switching of the color displayed on the first specific lamp unit 47 is performed, and a determination command is output to the display control device 214. By inputting this determination command, the display control device 214 controls the display of the symbol display device 41 so as to confirm and display the left, middle, and right symbols. As a result, the symbol variation display on the display screen of the symbol display device 41 and the color switching display displayed on the first specific lamp unit 47 are completed simultaneously at the timing t4. At the timing t4, a predetermined time has not elapsed since green is displayed on the first specific lamp unit 47. However, since the switching display time has elapsed, the switch of the green light source is turned off without being restricted thereby. The switch of the red light source is turned on. The on state of the switch of the red light source is continued until the next game time.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 41 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. In step S902, the process waits until a payout permission command transmitted from main controller 271 is received. When the payout permission command is received, the process advances to step S903 to permit RAM access, and in step S904, an external interrupt vector is set.

  Thereafter, a data backup process is executed for the RAM 513 in the CPU 511. That is, in step S905, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed, and in subsequent step S906, it is determined whether or not the information on occurrence of power shutdown is set in the backup area 513a of the RAM 513. To do. In step S907, a RAM determination value is calculated. In subsequent step S908, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. Note that it is possible to determine the validity of the backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If the RAM erase switch 323 has been pressed, the process proceeds to a RAM initialization process (steps S915 to S918). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (steps S915 to S918). . That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S909, the stack pointer prior to power shutdown is restored, and in step S910, information on occurrence of power shutdown is cleared. In step S911, the CPU peripheral device is initialized, and in step S912, the used register is restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the interruption permission / non-permission is returned to the state before the power interruption, and then the address before the power interruption is returned.

  Next, the flow of the payout control process will be described with reference to the flowchart of FIG.

  42, in step S1001, a command from the main controller 271 is acquired and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 16. That is, when the lower pan 16 is detected based on the detection signal of the lower pan full switch, when the lower pan is full, the lower pan full state is set, and when the lower pan is full, , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration.

  Thereafter, in step S1006, the presence / absence of a state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified.

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not in a payout disabled state and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009 and a prize to be described later shown in FIG. Start the ball control process. If the prize ball is not paid out or the total number of prize balls is 0 (YES in any of steps S1007 and S1008), the process proceeds to the lending / paying process in steps S1010 to S1012.

  In the rental ball payout process, if the rental ball payout is not disabled and a rental ball payout request is received from the card unit (NO in step S1010, YES in S1011), the process proceeds to step S1012 and is shown in FIG. The ball rental control process described later is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), subsequent ball removal processing is executed.

  In step S1013, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In subsequent step S1014, control of vibrator 360 (vibration motor control) is executed on condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  Here, in the winning ball control process shown in FIG. 43, in step S1101, the payout motor 358a is driven to execute payout of the winning ball. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process advances to step S1103 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process in FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to step S1104, and whether or not the game ball is normally counted is determined based on the detection result of the payout count switch. If the game ball count is not normal, the process proceeds to step S1105, where the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped, and then the process returns to the payout control process of FIG.

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, a stop process for the payout motor 358a is executed in step S1107, and then the process returns to the payout control process in FIG.

  In the ball lending control process shown in FIG. 44, in step S1201, the payout motor 358a is driven to pay out the lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1203, the payout motor 358a is driven to execute a retry process, and the stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process advances to step S1204 to determine whether or not the game ball is normally counted based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1205 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

  If the game ball count is normal, the process proceeds to step S1206, where it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed. If the payout has been completed, the stop process of the payout motor 358a is executed in step S1207, and then the process returns to the payout control process of FIG.

  Here, in the present embodiment, the LEDs 181, 182, and 183 provided on the light guide plates 171, 172, and 173 constituting the game board unit 30 are controlled to be turned on / off, so that the background color and background pattern of the game area Changes are made. Therefore, background mode control processing performed in the sound lamp control device 272 will be described below with reference to FIG. The background mode control process is executed as part of a process periodically performed in the sound lamp control device 272.

  First, in step S1301, it is determined whether an effect flag is set. The effect flag is a flag that is set when an effect command is output from the display control device 214 and is erased when an end command is output from the display control device 214. The effect command is a command that is output from the display control device 214 with a predetermined probability when a jackpot occurs, and the first variation type counter CS1 and the second variation type counter that the display control device 214 inputs from the main control device 271. Based on the value of CS2, it is output at a predetermined timing. It should be noted that the effect command is not output in game times where no big hit occurs. The end command is a command that is output when a determination command is input from the main control device 271 during the game round in which the display control device 214 outputs the effect command.

  If the effect flag is not set, the process proceeds to step S1302, and it is determined whether or not the pattern 1 setting flag is set. The pattern 1 setting flag is a flag for determining whether or not the background color and the background pattern are changed in the pattern 1 mode, and is set at least when the pachinko machine 10 is turned on. If the pattern 1 setting flag is set, the pattern 1 process is executed in step S1303, and the process returns to step S1301.

  Here, the pattern 1 process will be described with reference to FIG. In the pattern 1 process, first, in step S1401, it is determined whether or not the time measured by the light emission period measurement timer is 1 sec or more. When 1 sec or more has elapsed, the processing after step S1402 is executed, and when 1 sec or more has not elapsed, this processing is ended as it is. Here, the light emission period measurement timer is a count-up method, and starts measurement when the pachinko machine 10 is powered on. Accordingly, an affirmative determination is made in step S1401 after 1 sec has passed immediately after power-on.

  In step S1402, it is determined whether the emission color counter is 6. The light emission color counter is a counter that is referred to in order to determine which of the three types of LEDs 181, 182, and 183 is to be on / off controlled. If the emission color counter is not 6, the processes of steps S1403 to S1405 are executed.

  In step S1403, all the LEDs 181, 182, and 183 are turned off, and then the various LEDs 181, 182, and 183 are turned on with reference to the emission color counter. More specifically, when the emission color counter is 0, only the blue LED 181 is turned on. When the emission color counter is 1, only the red LED 182 is turned on. When the emission color counter is 2, Only the green LED 183 is turned on. When the emission color counter is 3, the blue and red LEDs 181 and 182 are turned on. When the emission color counter is 4, the red and green LEDs 182 and 183 are turned on. When the emission color counter is 5, the blue and green LEDs 181 and 183 are turned on. When the emission color counter is 6, all the LEDs 181, 182 and 183 are turned on.

  In step S1404, 1 is added to the emission color counter. That is, the light emission color counter is incremented by 1 every time the predetermined time (1 sec) elapses. Therefore, when the pattern 1 process is performed, the on-control of the LEDs 181, 182 and 183 corresponding to the light emission color counter described above is performed. Are performed in ascending order of the counter. In step S1405, the light emission period measurement timer is reset. Then, after the process of step S1405, the present process is terminated.

  On the other hand, if the emission color counter is 6, all the LEDs 181, 182 and 183 are turned off in step S 1406. Thereafter, in step S1407, the light emission color counter is reset, the pattern 1 setting flag is reset, and then the process ends.

  Returning to the description of the background mode control process, if the pattern 1 setting flag is not set in step S1302, a negative determination is made, the pattern 2 process is executed in step S1304, and the process returns to step S1301. In the pattern 2 process, substantially the same process as the pattern 1 process is executed. However, in the process corresponding to step S1401, it is determined whether or not 3 seconds have elapsed, and in the process corresponding to step S1407, the pattern 1 setting flag is set. On the other hand, if the effect flag is set in step S1301, an affirmative determination is made, and after pattern 3 processing is executed in step S1305, the processing returns to step S1301.

  Here, the pattern 3 process will be described with reference to FIG. In the pattern 3 process, first, in step S1501, it is determined whether or not the measured time measured by the light emission period measurement timer is 1 sec or more. If 1 sec or more has not elapsed, the processing is terminated as it is. That is, even if the effect flag is set, the lighting state of the LEDs 181, 182, and 183 when the effect flag is set is maintained until the time measured by the light emission period measurement timer becomes 1 sec or longer.

  If the time measured by the light emission period measurement timer is 1 sec or longer, an affirmative determination is made in step S1501, and the flow proceeds to step S1502. In step S1502, it is determined whether all the LEDs 181, 182, and 183 are on. If all the LEDs 181, 182, and 183 are not turned on, all the LEDs 181, 182, and 183 are turned on in step S 1503, and the light emission period measurement timer is reset in step S 1504. The process ends. On the other hand, if all the LEDs 181, 182, and 183 are turned on, in step 1505, all the LEDs 181, 182, and 183 are turned off, and in step S 1504, the light emission period measurement timer is reset. This process is terminated.

  Here, the background color / background pattern switching mode will be described with reference to FIG. For convenience of explanation, in the following explanation, the patterns shown in FIGS. 24A to 24C are referred to as patterns (a), (b), and (c).

  First, at the timing of t1, switching of the background color and the background pattern based on the pattern 1 is started when 1 sec elapses after the pachinko machine 10 is turned on. In this pattern 1, the LEDs 181, 182, and 183 corresponding to the respective colors in the order of blue → red → green → blue and red → red and green → blue and green → blue and red and green are turned on for 1 sec. . Therefore, from the front of the pachinko machine 10, the pattern (a) → the pattern (b) → the pattern (c) → the patterns (a) and (b) → the patterns (b) and (c) → (a) And the pattern of (c) → the patterns of (a) and (b) and (c) appear to shine in the corresponding colors, respectively.

  Then, at the timing t2, as the pattern 1 switching mode ends, the background color and background pattern switching based on the pattern 2 is started. In this pattern 2, the background color and the background pattern are switched in the same manner as in pattern 1, but the time during which the LEDs 181, 182 and 183 of the respective emission colors are on-controlled is 3 sec. Therefore, the background color and the background pattern are switched more slowly than the pattern 1. After that, when the pattern 2 switching mode ends at the timing t3, the switching mode based on the pattern 1 is started again. That is, the background color and the background pattern basically change alternately between the pattern 1 mode and the pattern 2 mode.

  In addition, at the timing t4, an effect command is output from the display control device 214, whereby switching of the background color and the background pattern based on the pattern 3 is started. In this pattern 3, the LEDs 181, 182, and 183 of the respective emission colors are repeatedly turned on repeatedly for 1 sec. Therefore, the patterns (a), (b), and (c) appear to shine repeatedly every 1 sec. Then, at the timing of t5, the end command is output from the display control device 214, whereby the switching based on the pattern 3 is completed, and the switching is started from the state before the switching based on the pattern 3 is started. That is, when the pattern 1 is shifted to the pattern 3 in the middle of the pattern 1, the pattern 1 is started in the middle of the pattern 1.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  Light guide plates 171, 172, and 173 are provided on the back side of the game region plate 160 that is transparent and has a game region formed thereon, and the game region is produced by the effects of light emitted from these light guide plates 171, 172, and 173. By adopting a configuration in which decoration is added, the degree of freedom in designing a region where light is rendered can be increased as compared to a conventional gaming machine, and decoration of a gaming region can be suitably added. That is, in the conventional gaming machine, the through hole is provided in the game board, and the light emitting body is turned on or blinked at the position where the through hole is provided, so that the decoration of the game area is enhanced. Although it is necessary to provide the light emitting body so as to avoid the disposed position, in the present embodiment, it is possible to design an area for performing light regardless of the position where the nail 39 or the like is disposed. Because.

  In addition, by setting it as the structure which forms uneven | corrugated | grooved part 171b, 172b, 173b only in the back surface of each light-guide plate 171,172,173, concavo-convex part 171b, 172b, 173b is formed in the surface of each light-guide plate 171,172,173. Compared with the structure which performs, the production of the light visually recognized from the front of the pachinko machine can be displayed clearly (the outer edge is sharper). In addition, for example, in a configuration in which uneven portions are formed on both front and back surfaces of each light guide plate 171, 172, 173, the light emitted from the LEDs 181, 182, 183 is transmitted through the uneven portions on the surface, so that the pachinko machine It radiates forward, and is radiated to the front of the pachinko machine by being irregularly reflected by the uneven part on the back surface. In this case, since the amount of light is different between the transmitted light and the reflected light, there is a risk that unevenness in the light effect will occur. On the other hand, since the uneven portions 171b, 172b, and 173b are formed only on the back surface, there is no possibility that the above-described inconvenience occurs.

  Further, the peripheral wall portions of the through holes 171a, 172a, 173a formed in the light guide plates 171, 172, 173, and the upper and left and right sides of the peripheral surface of the light guide plates 171, 172, 173 where the element substrate 180 is not provided. The light reflecting tapes 176, 177 as light reflecting means are attached so as to cover the peripheral surface of the light, so that the light totally reflected in the light guide plates 171, 172, 173 is the peripheral walls of the through holes 171a, 172a, 173a. Even if it reaches the peripheral surface of the part or the light guide plates 171, 172, 173, it does not leak out so much and is reflected by the light reflecting tapes 176, 177. Therefore, effective use of light can be achieved, and decoration of the game area can be suitably added.

  In particular, the through holes 171a, 172a, and 173a serve as passages for the game balls that have entered the general winning port 31, the variable winning device 32, and the operating port 33, so that the peripheral walls of the through holes 171a, 172a, and 173a are light reflecting tape 176 If it is not covered by the light, the light that totally reflects inside the light guide plates 171, 172, 173 is irradiated to the game balls that pass through the through holes 171a, 172a, 173a. In this case, it is conceivable that the reflected light on the surface of the game ball is confused with the light emitted through the concave and convex portions 171b, 172b, and 173b, which may cause inconveniences such as blurring of the light effect. . Further, in the configuration in which a plurality of light guide plates are connected as in the present embodiment, and LEDs 181, 182, and 183 having different emission colors are provided for each light guide plate, light irradiated to one light guide plate Reflecting on the surface of the game ball passing through the through holes 171a, 172a, and 173a, the light is introduced into another light guide plate, and there is a possibility that inconvenience that it is not possible to produce the light as designed. In contrast, since the peripheral wall portions of the through holes 171a, 172a, and 173a are covered with the light reflecting tape 176, it is possible to suppress the occurrence of the inconvenience as described above.

  In addition, a plurality of light guide plates 171, 172, 173 are provided, and the light emission colors of the LEDs 181, 182, 183 arranged on the light guide plates 171, 172, 173 are made different for each light guide plate 171, 172, 173. By this, the variation of the production of light can be increased and the decoration property of a game area can be improved more. The light source for introducing light into each light guide plate 171, 172, 173 is an LED, so that the power consumption of the light source can be reduced, the service life can be extended, and the display output can be increased. Can be stabilized.

  In addition, the light guide plates 171, 172, and 173 have a configuration in which a plurality of LEDs are provided along the lower surface on which the element substrate 180 is provided, so that the uneven portions 171 b of the light guide plates 171, 172, and 173 are arranged. , 172b, 173b can be made uniform when viewed from the front of the gaming machine. In addition, even if any of the plurality of LEDs breaks down, the effect of the light is continued by the light from the other LEDs, so that it is possible to prevent the decorativeness of the game area from being extremely lowered.

Further, in each light guide plate 171, 172, 173, resistors 184, 185, 186 for adjusting the amount of current flowing through the various LEDs 181, 182, 183 are arranged in a line with the various LEDs 181, 182, 183. Resistance 184, 185, 186
Since it is not necessary to secure a region for arranging the light guide plates 171, 172, and 173 in the thickness direction, the thickness dimension of the light guide plates 171, 172, and 173 can be reduced. As a result, the space for arranging the plurality of light guide plates 171, 172, 173 in the pachinko machine can be reduced as much as possible, and attenuation of light emitted from the light guide plate on the back side can be suppressed as much as possible. it can.

  Further, the LEDs 181, 182, and 183 provided on the respective light guide plates 171, 172, and 173 are mounted on a single element substrate 180, so that a plurality of LEDs 181, 182, and 183 are provided. , 182 and 183 can be easily attached.

  Further, concave portions 171c, 172c, 173c are formed on the lower surfaces of the respective light guide plates 171, 172, 173, and the LEDs 181, 182, 183 are disposed in the concave portions 171c, 172c, 173c, and the concave portions 171c, 172c, 173c, By adopting a configuration in which the 173c is formed so as to follow the outer shape of the LEDs 181, 182, and 183, the light emitted from the LEDs 181, 182, and 183 is irradiated radially to the corresponding light guide plates 171, 172, and 173. It will be. Thereby, the light irradiated from LED181,182,183 can be efficiently introduce | transduced in the light-guide plates 171,172,173.

  Further, by providing the element substrate 180 (LEDs 181, 182, 183) on the lower surface of each light guide plate 171, 172, 173, it is possible to secure the gaming area as wide as possible in the vertical and horizontal directions in the configuration including the element substrate 180. Can do. That is, the pachinko machine has a vertically long shape so that the vertical direction is the long side direction. Further, since the upper plate 23 and the like are provided below the position overlapping with the game board unit 30 on the front surface of the pachinko machine, there is a predetermined space below the game board unit 30 inside the pachinko machine. . In this case, by utilizing the space, an element substrate 180 is provided on the lower surface of each light guide plate 171, 172, 173, so that the upper and left and right ends of the game board unit 30 are connected to the pachinko machine in the configuration including the element substrate 180. Can be close to the upper end and the left and right ends. Therefore, in the configuration including the element substrate 180, the game board unit 30 can be suitably expanded vertically and horizontally, and accordingly, the game area can be secured as wide as possible vertically and horizontally.

  Further, the thickness of each light guide plate 171, 172, 173 is set to be approximately the same as the length of the LEDs 181, 182, 183 in the front-rear direction (thickness direction of each light guide plate 171, 172, 173), and each light guide plate 171, 172, 173 By adopting a configuration in which the respective opposing surfaces are in contact with each other, the space for arranging the plurality of light guide plates 171, 172, and 173 inside the gaming machine can be made as small as possible. In this case, the LEDs 181, 182, and 183 respectively disposed on the adjacent light guide plates 171, 172, and 173 are arranged on the element substrate 180 so as not to line up in the thickness direction of the light guide plates 171, 172, and 173. did. Accordingly, in the configuration in which the distance between the LEDs 181, 182, 183 in the thickness direction of the light guide plates 171, 172, 173 on the element substrate 180 is narrowed, the mounting work of the LEDs 181, 182, 183 on the element substrate 180 is easy. Can be done.

  Further, the game area plate 160, the light guide plates 171, 172, 173, and the mounting plate 190 are fixed by screws 161 so as to be unitized as the game board unit 30, thereby the main body of the pachinko machine 10 (resin base 25). ) Can be easily attached to the plates 160, 171, 172, 173, 190. In this case, the screws 161 are inserted and fixed to the openings formed so as to be coaxial with the four corners of the game area plate 160, the light guide plates 171, 172, 173, and the mounting plate 190. By adopting a configuration in which 160, 171, 172, 173, and 190 are fixed, the unitization can be suitably performed. For example, in the configuration in which an adhesive is applied and fixed to the facing surface between the game area plate 160 and the light guide plate 171 and the facing surfaces between the light guide plates 171, 172, 173, bubbles are generated inside and are manufactured. This is because there is a risk that the defect rate in such cases will increase.

  In addition, by setting the resistance value of the resistor disposed on the element substrate 180, the brightness of the light radiated from each light guide plate 171, 172, 173 is visually recognized from the front of the game machine. Thus, the player's line of sight can be evenly directed to the light emitted from the light guide plates 171, 172, 173. Thereby, the effect which provided the some light-guide plate 171,172,173 can be drawn out suitably.

  In addition, each LED 181, 182, and 183 is configured by attaching a light reflecting tape 175 as a light reflecting means between each LED 181, 182, and 183 provided in each adjacent light guide plate 171, 172, 173. Is suppressed from being introduced into the light guide plate located adjacent to the light guide plate on which the LEDs 181, 182, and 183 are disposed. Thereby, since the color of the light radiated | emitted from each light-guide plate 171,172,173 becomes the light emission color of LED181,182,183 arrange | positioned at the light-guide plate, the production of light can be performed as designed. .

  Further, by forming the game area plate 160 from polycarbonate resin, even if the game ball collides with a nail 39 or the like disposed on the surface, the game area plate 160 is not easily cracked. This is because the polycarbonate resin has a relatively high elasticity. Further, by forming the light guide plates 171, 172, and 173 with an acrylic resin, the light transmittance of the light guide plates 171, 172, and 173 is enhanced, and the light emitted from the LEDs 181, 182, and 183 is effectively used. be able to.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the game area plate 160 made of polycarbonate resin is provided, and the game area is formed by disposing the nail 39 or the like on the surface of the game area board 160. May be. For example, it is good also as a structure which forms a game area board with an acrylic resin, and also provides LED in the surrounding surface. In this case, since it is possible to emit light from the game area board, it is possible to diversify the effects of light as compared to the above embodiment without increasing the thickness of the game board unit 30.

  Moreover, since light is radiated from the game area plate, even if the light guide plates 171, 172, and 173 are not provided on the back side of the game area plate, it is possible to produce light. Therefore, the dimension in the thickness direction of the game board unit 30 can be shortened as much as possible while ensuring the addition of decorativeness to the game area.

  In addition, since acrylic resin is generally less elastic than polycarbonate, if a game ball repeatedly collides with the nail 39 or the like disposed, the game area plate may be damaged by the impact. Therefore, in a configuration in which the game area plate is formed of acrylic resin as in this configuration, it is preferable to add a predetermined amount of synthetic rubber such as butadiene to the acrylic resin. Further, the addition amount of the synthetic rubber is more preferably 20 to 30%. In this case, the elasticity can be increased while suppressing the light transmittance from being extremely lowered.

  (B) In the above embodiment, three light guide plates 171, 172, 173 are arranged. However, this may be changed. For example, the structure which arrange | positions only 1 sheet or 2 sheets may be sufficient. In these cases, the dimension in the thickness direction of the game board unit 30 can be made shorter than in the above embodiment. Moreover, the structure which arrange | positions four or more sheets may be sufficient. In this case, the light effects can be further diversified.

  (C) In the above embodiment, the concave and convex portions 171b, 172b, and 173b are formed on the back surfaces of the light guide plates 171, 172, and 173. The structure by which uneven | corrugated | grooved part 171b, 172b, 173b is formed in both may be sufficient. In this case, the degree of freedom of the region where the uneven portions 171b, 172b, and 173b are formed is higher than that in the above embodiment. Moreover, the structure by which the uneven | corrugated | grooved part 171b, 172b, 173b is formed in the surface of the light-guide plates 171,172,173 may be sufficient.

  (D) In the above embodiment, a plurality of LEDs 181, 182, and 183 are provided as light sources of the light guide plates 171, 172, and 173, but this may be changed. For example, as shown to Fig.49 (a), the structure which provides the fluorescent lamp 195 as a light source may be sufficient. In this case, by setting the length of the fluorescent lamp 195 to be approximately the same as the length of the light guide plates 171, 172, 173, light can be introduced into the light guide plates 171, 172, 173 from the entire circumference. .

  (E) As a light source of the light guide plates 171, 172, and 173, a single color light emitting type LED may be used instead of a multicolor light emitting type LED. In this case, it becomes possible to irradiate each light guide plate with light of various colors, and the light effects can be further diversified.

  (F) As shown in FIG. 49 (b), a configuration may be adopted in which a wall portion 196 a that blocks between the various LEDs 181, 182, and 183 is integrally formed on the element substrate 196. In this case, by forming the element substrate 196 from a material having a light blocking property, it is possible to suppress the light irradiated from the various LEDs 181, 182, and 183 from being irradiated into the incompatible light guide plates 171, 172, and 173. . Further, a light reflecting means such as a light reflecting tape may be provided on the wall 196a. In this case, when the light emitted from the LEDs 181, 182, and 183 reaches the wall portion 196 a, the light is reflected by the light reflecting means and travels through the light guide plate, so that the light is more effective than blocking light. Can be used.

  (G) In the above embodiment, openings are formed at the four corners of the game area plate 160, the light guide plates 171, 172, 173, and the mounting plate 190, and the screws 161 are inserted into and fixed to the openings. Although 160, 171, 172, 173, and 190 are unitized as the game board unit 30, this may be changed as shown in FIG. 49 (c). That is, an L-shaped corner fixture 197 may be provided so that all the plates 160, 171, 172, 173, and 190 are sandwiched between the four corners of the plates 160, 171, 172, 173, and 190. In this case, since it is not necessary to provide openings at the four corners of the light guide plates 171, 172, 173, it is possible to eliminate leakage of light from the openings.

  (H) In the above embodiment, the red LEDs 182 are arranged so as to be shifted with respect to the arrangement positions of the blue LEDs 181 and the green LEDs 183 so that the LEDs 181, 182, and 183 are not arranged in a line in the width direction of the element substrate 180. However, the LEDs 181, 182, and 183 may be arranged in a line in the width direction of the element substrate 180 by making the arrangement positions of the LEDs 181, 182, and 183 the same. In this case, the distance between the LEDs 181, 182, and 183 along the circumferential direction of the light guide plates 171, 172, and 173 on the element substrate 180 can be reduced, so that more LEDs 181 and 182 than those in the above embodiment are used. , 183 can be provided. Moreover, it is good also as a structure arrange | positioned so that only LED corresponding to two adjacent light-guide plates (partial light-guide plates) among various LED181,182,183 may not be located in a line.

  (I) In the above embodiment, the plurality of LEDs 181, 182, and 183 disposed on one light guide plate 171, 172, and 173 have the same configuration in the thickness direction dimension of the light guide plate. It is good also as a structure which arrange | positions multiple types of LED from which a direction dimension differs with respect to one light-guide plate. In this case, the LED having the largest dimension in the thickness direction in the LEDs of each light guide plate is arranged so that the LEDs in the thickness direction of the light guide plate are not arranged on the element substrate 180, so that the heat generated from one LED is adjacent to the light guide plate. Therefore, it is difficult to transmit to the LED disposed on the LED, and it is possible to suppress the occurrence of inconvenience such as failure of the LED. Also, the LED mounting operation on the element substrate 180 can be easily performed.

  (J) In the above embodiment, the light reflecting tape is used as a light reflecting means on the peripheral wall portions of the through holes 171a, 172a, 173a of the light guide plates 171, 172, 173 and the peripheral surfaces of the light guide plates 171, 172, 173. Although 176 and 177 are provided, this may be changed. For example, instead of the light reflecting tapes 176 and 177, a metal additive paste such as a silver paste may be applied.

  (K) In the above embodiment, the thicknesses of the plates 160, 171, 172, 173, and 190 constituting the game board unit 30 are the same, but this may be changed. For example, the light guide plates 171, 172, and 173 may be configured to be thinner than the game area plate 160. That is, the nail 39 is implanted on the surface of the game area plate 160, but it is necessary to insert the nail 39 to a certain depth in order to hold the nail 39 in a stable state. Therefore, the game area plate 160 needs to have a thickness that can hold the nail 39 in a stable state. On the other hand, the light guide plates 171, 172, and 173 only need to have a function of radiating light forward of the pachinko machine, and therefore do not require as much thickness as the game area plate 160. By adopting this configuration, the thickness of the game board unit 30 can be made thinner than that in the above embodiment, so the space for arranging the game board unit 30 inside the pachinko machine can be reduced, This makes it possible to effectively use the space inside the pachinko machine.

  (L) The method of forming the uneven portions 171b, 172b, and 173b is not limited to a mechanical etching method. For example, the uneven portions 171b, 172b, and 173b are chemically patterned using a chemical solution or the like. Also good.

  (M) Although the light guide plates 171, 172, and 173 are provided with the uneven portions 171 b, 172 b, and 173 b as the irregular reflection regions, the method of forming the irregular reflection regions may be changed. For example, the light guide plates 171, 172, and 173 may be configured to embed irregular reflection members having a different refractive index from the light guide plate. In this case, light is diffusely reflected at the boundary surface between the irregular reflection member and the light guide plate, so that light can be emitted toward the front of the pachinko machine. In addition, if a configuration in which a large number of relatively small-diameter beads are embedded as the irregular reflection member, a boundary surface between the irregular reflection member and the light guide plate can be secured as much as possible, and the irregular reflection member is disposed in front of the pachinko machine. The amount of light radiated toward can be increased.

  (N) In the above embodiment, the mounting plate 190 is provided as the game board unit 30, but a configuration in which the mounting plate 190 is not provided may be used. In this case, it is necessary to add the function of the mounting plate 190 to the light guide plate 173 located on the innermost side.

  (O) It is good also as a structure which forms the some through-hole penetrated in the thickness direction in the attachment plate 190, and arrange | positions light-emitting bodies, such as LED, in each through-hole. Alternatively, the mounting plate 190 may be formed of a transparent synthetic resin, and a light emitting body such as an LED that emits light toward the front of the pachinko machine may be provided on the back side of the mounting plate 190. However, the cell attached to the mounting plate 190 is formed of a light-transmitting material. In these cases, the effects of light can be further diversified by the combination with the light emitted from the light guide plates 171, 172, 173.

  (P) In the above embodiment, the light reflecting tape is provided between the various LEDs 181, 182, and 183, but the light blocking tape as the light blocking means may be provided. . Even if it is the said structure, it can suppress that the light irradiated from various LED181,182,183 is introduce | transduced in the light-guide plate 171,172,173 located next.

  (Q) In the above embodiment, the various LEDs 181, 182, and 183 are configured to be turned on and off in the three modes of pattern 1 to pattern 3, but this may be changed. For example, a configuration having four or more patterns may be used. In this case, the effects of light can be further diversified, and the decoration of the game area can be further improved. Moreover, the structure which a pattern has only 1 or 2 aspects may be sufficient. In this case, the processing load of the sound lamp control device 272 can be reduced. Moreover, although the configuration in which the pattern 3 mode is generated only in the game times in which the jackpot is generated, the configuration in which the pattern 3 mode is generated with a predetermined probability of the game times in which the reach is generated may be employed.

In this case, the main controller 271 is configured to turn on and off the LEDs 181, 182, and 183 provided on the light guide plates 171, 172, and 173, and the first specific light is emitted from the light guide plates 171, 172, and 173. The function of the lamp unit 47 and / or the second specific lamp unit 48 may be added.

  (S) In the above embodiment, the main controller 271 is configured to determine a fine combination of stop symbols, a symbol variation pattern, and a reach effect in the symbol display device 41, but this may be changed. . For example, the main control device 271 may have a configuration in which the display control device 214 determines these without determining a fine combination of stop symbols, a symbol variation pattern, and a reach effect in the symbol display device 41. In this case, the main control device 271 displays on the first specific lamp unit 47 whether the jackpot that is in the probable change state, the jackpot that is in the normal state, or no jackpot occurrence occurs in the game times. A display command including the color switching display time is output to the display control device 214. Then, the display control device 214 determines a fine combination of stop symbols, a symbol variation pattern, and a reach effect based on the display command from the main controller 271 and displays the symbol variation display within the range of the switching display time. To control. With this configuration, the processing load on the main controller 271 can be reduced.
