  In the pachinko machine 10, a glass door frame and a front decoration frame are individually provided, and these can be opened and closed with respect to the front frame (corresponding to the main body frame of the present embodiment), and an upper plate is provided on the front decoration frame. Unlike the conventional configuration, the glass door frame and the front decoration frame are integrated into a front door frame 13, and the upper plate 23 is provided integrally with the front door frame 13. In this case, since the glass door frame and the front decoration frame are integrated into the front door frame 13, the strength of the glass support structure can be improved in the front door frame 13. That is, in this pachinko machine 10, for the purpose of expanding the game area, a large glass 137 is mounted on the front door frame 13 along with the expansion of the game area. Therefore, although the frame portion around the glass becomes narrow and there is a concern about the problem of strength reduction, sufficient strength of the glass support structure can be ensured by providing a frame portion integrated with the upper plate below the glass. The vertical and horizontal dimensions of the glass 137 are generally 405 mm × 405 mm, whereas the pachinko machine 10 has a size of 453 mm × 434 mm.

  The front door frame 13 is extended downward so as not to interfere with the game ball launching handle 18 at least when opening and closing the front door frame 13. Specifically, the dimension La from the lower end of the pachinko machine to the lower end of the front door frame 13 is, for example, about 201 mm in one existing model, whereas in this pachinko machine 10, it is about 30 mm smaller, about 172 mm. It has become. Along with this, the dimension Lb from the lower end of the pachinko machine to the upper end of the upper plate 23 is also reduced, which is about 298 mm in the existing model, for example, about 261 mm in the present pachinko machine 10. Here, by lowering the position of the upper plate 23, the vertical distance from the tip of the nozzle of the ball lending device arranged side by side on the left side of the pachinko machine 10 in the game hall increases, and there is a concern that the lending of the ball will spill out. However, in the present embodiment, the rising portion 22a in which the wall surface of the bulging portion 22 is higher than the other wall surface is formed in the left side portion that is the rental ball discharge portion from the nozzle. Thereby, even if it has the structure which lowered | hung the position of the upper plate 23, inconveniences, such as spilling of a rental ball, are eliminated. The height dimension of the rising portion 22a may be anything that matches the lowered dimension of the upper plate 23, and the maximum height dimension is 25 mm in the present embodiment.

  In the front door frame 13, the bulging portion 22 for forming the upper plate is provided so as to bulge greatly toward the front side, but other portions above the upper plate 23 (annular electric decoration portion 102 and the like to be described later) ) Is restricted to bulge to the near side to avoid interference with the nozzle of the ball lending device. Specifically, the dimension from the outer frame 11 toward the front side is limited to 45 to 50 mm.

  As shown in FIG. 3, the main body frame 12 is mainly composed of a resin base 25 whose outer shape is substantially the same as that of the outer frame 11, and a substantially circular window hole 26 is formed at the center of the resin base 25. Is formed. A game board 30 is detachably mounted on the rear side of the resin base 25. As shown in FIG. 4, the game board 30 is made of a substantially rectangular plywood, and is attached in a state where the peripheral edge thereof is in contact with the back side of the resin base 25. That is, the game board 30 is attached from the rear of the pachinko machine 10, and only the substantially central portion of the front part of the game board 30 is exposed to the front side of the main body frame 12 through the window hole 26 of the resin base 25. Note that the gaming board 30 has a vertical length of 476 mm and a horizontal length of 452 mm, as in the prior art.

  Next, the structure of the game board 30 is demonstrated based on FIG. The game board 30 is formed with a plurality of large and small openings penetrating in the front-rear direction by being subjected to router processing. Each opening is provided with a general winning port 31, a variable winning device 32, an operating port 33, a through gate 34, a variable display unit 35, and the like. Actually, the general winning port 31, the variable winning device 32, the operating port 33, the through gate 34, and the variable display unit 35 are attached to the surface of the game board by wood screws or the like. In the present embodiment, the variable display unit 35 is disposed substantially at the center of the game board 30, the operation port 33 is disposed below the variable display unit 35, and the variable winning device 32 is disposed further below. In addition, through gates 34 are arranged on the left and right sides of the variable display unit 35, and a plurality of general winning holes 31 are arranged on both sides of the lower part of the game board 30. The operating port 33 is additionally provided with an electric accessory that is activated (opened) under a predetermined condition. When a game ball enters the general winning port 31, the variable winning device 32, and the operating port 33, it is detected by a detection switch which will be described later, and based on the detection result, the upper plate 23 (in some cases, the lower plate 16) is detected. A predetermined number of prize balls are paid out. In addition, an out port 36 is provided at the lowermost part of the game board 30 so that game balls that have not entered various winning ports etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. The out port 36 is formed by cutting out the substantially lower center of the game board 30 in an inverted U shape. Therefore, compared to the conventional configuration in which the out port is formed in a hole shape, the out port can be formed more easily (however, in FIG. Is shown). The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (functions) such as a windmill 37 are disposed.

  Notches 38 as recesses are formed at a plurality of locations on the left and right sides of the game board 30 so as to avoid interference with the protruding areas from the left and right sides of the body frame 12 that is the assembly partner.

  As described above, in the pachinko machine 10, the position of the upper plate 23 is lowered, and accordingly, the position of the game ball intake port provided in the most downstream portion of the upper plate 23 is also lowered. In this case, in the conventional configuration in which the game ball inlet is at a relatively high position, the game ball inlet and the game board 30 overlap each other, and the game board 30 has a notch corresponding to the game ball inlet. In this pachinko machine 10, the game ball intake port and the game board 30 do not overlap each other by lowering the game ball intake port. No formation is necessary. Therefore, it becomes an advantageous configuration in the manufacturing process of the game board 30.

  The variable display unit 35 is provided with a symbol display device 41 for variably displaying the first symbol (special symbol) with a winning at the operation port 33 as a trigger. The variable display unit 35 is provided with a center frame 43 so as to surround the symbol display device 41. The center frame 43 has an upper portion extending forward of the pachinko machine 10. As a result, the game ball is prevented from dropping in front of the display screen of the symbol display device 41, and the inconvenience that the visibility of the display screen is lowered due to the fall of the game ball does not occur. . In the upper center of the center frame 43, a first specific lamp portion 47 and a second specific lamp portion 48 are provided side by side. Further, a holding lamp 44 corresponding to the first specific lamp unit 47 and the symbol display device 41 is provided so as to sandwich the area where both the specific lamp units 47 and 48 are disposed. The number of times that the game ball has passed through the operation port 33 is held up to 4 times, and the number of the hold is displayed by turning on the hold lamp 44. Note that the hold lamp 44 may be configured to be variably displayed on a part of the symbol display device 41. As described above, since the upper portion of the center frame 43 extends forward of the pachinko machine 10, the visibility of the holding lamp 44, the first specific lamp portion 47, and the second specific lamp portion 48 is hindered by the fall of the game ball. It is the composition which is not done. A holding lamp 46 corresponding to the second specific lamp portion 48 is provided below the center frame 43. The number of times that the game ball has passed through the through gate 34 is held up to a maximum of 4 times, and the holding number is displayed by turning on the holding lamp 46. Note that the hold lamp 46 may have a configuration in which the display is variably displayed in a part of the symbol display device 41, similarly to the hold lamp 44.

  The symbol display device 41 is configured as a liquid crystal display device provided with a relatively large liquid crystal display of 8 inches, and the display content is controlled by a display control device described later. On the symbol display device 41, for example, the first symbols are displayed side by side on the left, middle, and right, and these symbols are variably displayed as they are scrolled up and down. When a predetermined symbol combination is stopped and displayed on a preset active line, a big win is generated and the subsequent gaming state is shifted to a big winning state as a special gaming state. This symbol variation display will be described in detail later. In addition, the symbol display device 41 has a display screen according to other types such as a CRT, a dot matrix, a 7-segment display, or the like provided with a liquid crystal display such as a 10-inch or 7-inch other than the 8-inch. It may be configured.

  The first specific lamp portion 47 is provided with a red, green, and blue three-color light emission type LED lamp. Then, the emission color is switched in a predetermined order using a winning at the operation port 33 as a trigger. Specifically, red light is turned on with a winning at the operation port 33 as a trigger, and the emission color is switched to green light when a predetermined time elapses in that state. Then, when the predetermined time elapses with the green light turned on, the emission color is switched to blue light. Thereafter, the emission color is repeatedly switched in the order of red, green, and blue until the emission color switching stop time comes. Accordingly, red, green, and blue are repeatedly displayed in this order on the first specific lamp unit 47. Finally, when red or green is stopped and displayed, the jackpot is generated and the subsequent gaming state shifts to the jackpot state. When blue is stopped and displayed, the jackpot is not generated and the jackpot is generated. Does not transition to the state. Further, in the present embodiment, the jackpot state to be transferred is different between the case where the stop is finally displayed in red and the case where the stop is finally displayed in green, and the latter is more advantageous to the player. Transition to jackpot state. The switching of the emission color will be described in detail later.

  On the other hand, the second specific lamp portion 48 is provided with red and green two-color light emitting type LED lamps inside. In the second specific lamp unit 48, the emission color is switched in a predetermined order with the passage of the through gate 34 as a trigger. Specifically, when the game ball passes through the through gate 34, lighting of red light and lighting of green light are alternately performed. Thus, red and green are alternately displayed on the second specific lamp unit 48. When the red color is stopped and displayed, the electric accessory attached to the operation port 33 is opened for a predetermined time.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which the game ball is easy to win when it shifts to a big win state. More specifically, when shifting to the big hit state, the variable winning device 32 is in a predetermined open state, and the game ball is easily won. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, the variable winning device 32 is repeatedly opened with a condition for transition to a round established, with a maximum of a plurality of rounds (for example, 16 rounds).

  The game board 30 is provided with a rail unit 50 as a rail member for guiding the game ball launched from the game ball launching device to the upper part of the game board 30. The launched game ball is guided to a predetermined game area through the rail unit 50. The rail unit 50 is composed of a ring-shaped resin molded product, and more specifically, a fluorine-containing polycarbonate resin is used to reduce frictional resistance. The rail unit 50 has an inner rail portion 51 and an outer rail portion 52 that are provided in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion, and the outer rail portion 52 surrounds the upper open area of the inner rail portion 51 and is parallel to the left side portion of the inner rail 51. Are formed in a substantially semi-annular shape.

  The inner rail portion 51 is integrally formed with other resin portions, and is provided upright substantially vertically on the surface of the game board 30. Further, the outer rail portion 52 has a support portion 52a that is integrally molded with other resin portions in the same manner as the inner rail portion 51, and is provided substantially upright on the surface of the game board 30. A sliding plate 52b is attached to the inner surface of 52a to make the flight of the game ball smoother. The sliding plate 52b is made of a long metal strip made of stainless steel, and is supported by the support portion 52a at a plurality of locations. In such a case, a guide rail is constituted by the inner rail portion 51 and the outer rail portion 52, and a ball guide passage is formed by a portion where these rail portions 51 and 52 face each other with a predetermined interval. In addition, in the site | part which the inner and outer rail parts 51 and 52 oppose, each rail part 51 and 52 is connected by the contact part 53 with the game board 30, and a ball | bowl guide path is formed in the groove shape open | released to the near side. Has been.

  In the rail unit 50, a return ball prevention member 54 is attached to a portion (the upper left portion in FIG. 4) from which the game ball jumps out of the ball guide passage, and a portion corresponding to the maximum flight portion of the jumped game ball (FIG. 4). In the upper right part), a return rubber 55 is attached. The return ball prevention member 54 prevents a situation in which a game ball that has once jumped from the ball guide passage to the upper portion of the game board 30 returns to the ball guide passage. In addition, the game ball launched at a predetermined momentum or more hits the return rubber 55 and is rebounded toward the center of the game area.

  An arc-shaped flange 56 projecting outward is formed on the outer periphery of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30. Here, the upper and lower and left and right ends of the rail unit 50 are formed in a substantially linear shape. That is, the flanges 56 are cut off at the upper and lower and left and right ends of the rail unit 50 so that the rail diameter can be expanded in a finite area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. It has become. The rail unit 50 is disposed such that the position of the gaming area on the gaming board 30 that is the maximum width reaches the left and right end positions of the gaming board 30. Among the parts corresponding to the ball guide passages of the rail unit 50, particularly with respect to the game ball receiving part, the corresponding flange 56 is provided from others in order to firmly attach the rail unit 50 and stabilize the flight of the game ball. There are also many screws (three in this embodiment, two in the other).

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail portion 52 so as to close a part of the ball guide passage. The convex portion 57 is formed so as to extend downward from the outer peripheral portion of the inner rail portion 51, and has a function of guiding a foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage 76 (see FIG. 3). Have The lower right corner and the lower left corner of the game board 30 are spaces (Sa, Sb in the figure) for sticking seals and plates such as certificate stamps, and in order to secure this attachment space, the flange 56 Notches 58a and 58b are formed in the upper and lower portions. By adopting a configuration in which a sticker such as a stamp is directly pasted on the game board 30, it is difficult to improperly paste the stamp or the like.

  In the game board 30, a relay terminal hole 59 penetrating in the front-rear direction is provided in the upper left portion outside the rail unit 50, and through this relay terminal hole 59, a connector for connecting a relay terminal plate installed on the back of the game board 60 is exposed to the front side of the pachinko machine 10.

  Next, the game area will be described. The board surface of the game board 30 is divided into inner and outer areas by a rail unit 50 (inner and outer rail portions 51 and 52), and an inner area divided into a substantially circular shape is a game area. In particular, in the present embodiment, the game area partitioned on the board surface of the game board 30 is configured to be much larger than before. In the present embodiment, the distance from the uppermost point of the outer rail portion 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the extreme left position of the inner rail portion 51 from the extreme left position of the outer rail portion 52. The distance between them is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail portion 51 to the extreme right position of the inner rail portion 51 is 418 mm.

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. 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 30 in which the out port 36 is formed, and the upper limit position of the game area. Is specified by the outer rail portion 52. Therefore, in the present embodiment, the width of the gaming area (maximum width in the left-right direction) is 418 mm, and the height of the gaming area (maximum width in the vertical direction) is 445 mm.

  Here, the width of the gaming area is preferably at least 380 mm. More preferably, it is 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. That is, the width dimension of the game area is preferably as large as possible from the viewpoint of game area expansion. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more or 480 mm or more. In other words, the height of the game area is preferably as large as possible from the viewpoint of game area expansion. In addition, about the combination of the said width | variety and height, it can be set as what combined the said numerical value arbitrarily. If the width or height of the game area exceeds a certain value, a part of the game area may exceed the board surface of the game board 30, but other members are placed along the game board surface in the area beyond the game area. What is necessary is just to supplement by providing.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is a much larger area ratio than before. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the related art, so that the game board 30 having the same size as the conventional one is used as in the present embodiment. So, it can be said that the game area is considerably expanded. It should be noted that the outer shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 has to be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more. In order to secure 80% or more, it is difficult to make the shape of the game area into a substantially circular shape. Therefore, it is preferable to have a shape in which the corner (for example, the lower right corner or the upper right corner) is expanded. .

  Moreover, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 10 is about 40%, which is a much larger area ratio than before. The area ratio of the game area to the area on the front side of the entire pachinko machine 10 is desirably 35% or more. Of course, it may be 40% or more, 45% or more, or 50% or more.

  In connection with the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable prize-winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided in the center of the game area, the through-gate 34, the windmill 37, and a plurality of nails are provided on the left and right sides of the variable display unit 35. (Guide nails such as a triangular nail for guiding the game ball to the center) and other objects can be provided with a margin, and the flow of the game ball in the game areas on the left and right sides of the variable display unit 35 It is not monotonous and you can fully enjoy the behavior of the game ball.

  Notches 38 are formed on both the left and right sides of the game board 30 to avoid interference with the protruding areas from the left and right sides of the main body frame 12, and the maximum width of the game area on the game board 30 in the rail unit 50 It has already been described that the position reaches the left and right end positions of the game board 30, but as will be described later, reinforcing members (bearing brackets 235: FIG. 9) provided on the left and right side portions of the main body frame 12. The game board 30 is attached to the main body frame 12 so as to have a width that leaves an area for arranging the locking device (the base frame 247, the interlocking rod 248, etc .: see FIG. 9). For these reasons, the game area is being expanded.

  Returning to the description of FIG. 3, in the resin base 25, below the window hole 26 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher is attached. Yes. 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 that is 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. As described above, the curvature of the ball guide passage is reduced because the game area has been greatly expanded as compared with the prior art, and thus a device for stabilizing the launch ball is required. Therefore, in the present embodiment, the launch position of the game ball is lowered so that the inclination angle (launch angle) of the launch rail 61 is somewhat larger than the existing one (that is, the launch rail 61 is raised), and By forming the launch rail 61 so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area, the launch rail 61 is made longer than the existing one and sufficiently long. The ball guide distance is secured. Thereby, the game ball launched from the game ball launching device can be guided to the ball guide passage in a more stable state. Further, in order to stabilize the launch ball, the metal plate 62 provided with the launch rail 61 is enlarged, and the metal plate 62 is screwed at a number of locations (15 to 20 in this embodiment). Thus, the launch rail 61 is firmly positioned with respect to the game board 30.

  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. Therefore, 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. Incidentally, in the case of the present embodiment, the length of the launch rail 61 is about 240 mm, and the length of the gap (the length on the extension line of the launch rail 61) leading to the foul ball passage 76 at the tip of the launch rail is about 40 mm. .

  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, since the launch position of the game ball is lowered in this embodiment, the drop from the exit of the ball on the front door frame 13 side to the launch position becomes large, Guide members 63 and 64 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front door frame 13 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device is provided with a ball striking rod that is supported so as to be rotatable about the base end portion, and a game ball is launched along with the rotation of the ball striking ball. It is rare. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to a light metal such as aluminum and reducing the size of the hitting shaft, the head portion of the hitting ball (opposite to the base end) is required to ensure sufficient firing force. A weight is provided at the tip of the side. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, the hitting ball can be easily picked or caught, and the effect of facilitating adjustment of the hitting strength of the hitting tip can be obtained.

  A pair of left and right discharge ports 66, 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, 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.

  The resin base 25 is provided with a substantially rectangular small window 78 at the lower right portion of the window hole 26. Accordingly, the stamp or the like attached to the lower right corner space (Sa in FIG. 4) of the game board 30 can be viewed through the small window 78. It is also possible to directly paste a stamp or the like on the game board 30 from the small window 78.

  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 30 described in FIG. 4 in substantially the same shape as that. The connection connector 60 of the terminal board 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 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 body frame 12 with respect to the outer frame 11 and locking and unlocking the front door frame 13 with respect to the main body frame 12 is installed at the lower right corner of the main body 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. Above the window part 101 of the front door frame 13, the frame width of the narrowest part is about 61 mm. 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, and is 85 mm to It is significantly shorter than the conventional model having the frame width of about 95 mm. 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 dimension of the frame width (narrowest part) above the window 101 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be secured, the thickness may be 50 mm or less.

  The left and right frame portions of the front door frame 13 are restricted in reducing the frame width, and need a width dimension sufficient to ensure the strength of the front door frame 13 itself and the glass support strength. In the present embodiment, the narrowest part of the left and right frame parts has a frame width of about 44 mm. In this case, since the game area has been greatly expanded in this pachinko machine 10, the frame width of the front door frame 13 is about 44 mm as described above on the left side when viewed from the front of the pachinko machine 10, that is, on the opening / closing axis side. On the other hand, the distance between the left end position of the outer rail portion 52 of the rail unit 50 and the left end position of the main body frame 12 is about 21 mm, and the latter dimension is considerably small. That is, in this configuration, in a state where the front door frame 13 is closed, a part of the ball 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 view 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.

  Small windows 107 to which a transparent resin is attached are provided on both the left and right sides of the lower end portion of the front door frame 13 so that a part of the surface of the main body frame 12 and the surface of the game board 30 (including certificate paper) can be visually recognized. The transparent resin attached to the small window 107 is formed in a flat shape so that the internal certificate paper or the like can be easily machine-read in a factory or the like. However, the small window 107 can be provided with a magnifying lens portion so that the hall operator or the like can easily see the internal certificate paper or the like.

  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 in a big hit state or at a predetermined reach performance. 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 state has been reached by turning on or blinking under 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. The inner surface of each resin cover layer intersects with each layer vertically and horizontally. A protrusion (or a wavy protrusion) is provided in the direction to be turned. 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 a card frequency check can be performed by the lending operation unit 120 in a state where a bill or a card is inserted into a card unit (a 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 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, reinforcement plates 131, 132, 133, and 134 are respectively 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. 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. And the assembly | attachment metal fittings 151 and 152 by the side of the front door frame 13 are attached with respect to the support metal fittings 81 and 82 (refer FIG. 3) by the side of the main body frame 12. FIG. 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). Accordingly, 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 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 on the opposite side to the open / close axis 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, the pachinko machine 10 according to the present embodiment is designed to expand the game area. 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 by 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 this 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 being 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. 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 extending in an arc shape along the inner edge and protruding 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 the gap between the front door frame 13 and the main body frame 12 to perform an illegal act, the wire or the film is allowed to enter the 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 protrusion 142 may be formed in a wider range, for example, along the entire area of the inner edge of the rail cover 140. According to such a configuration, it becomes difficult to infiltrate a wire, a film, or the like in a wider range, It is possible to more reliably prevent fraudulent acts that are performed using wires or films.

  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 major 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, various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board 271a) and the voice lamp controller 272 (voice lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) is launched. A control device 312 (launch control board) and a power supply device 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 also integrated as one unit, and the resin portion is generally referred to as a back pack, this unit is referred to as a “back pack unit 203” herein. 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 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 at the left end portion thereof, that is, the open end side opposite to the support shaft portion M4, and the second control board unit 202 performs the second control. 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 removed in a state where 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, rotating the unit 201 around the axis A, and expanding the unit 201. 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 is fastened and the locking portions M8 and M9 are unlocked, the unit 203 is rotated about the axis C, and is unfolded, and lifted in that state. Thereby, the back pack unit 203 can be removed.

  Here, the unfolding directions of the units 201 to 203 are not the same, and the first control board unit 201 opens to the left when 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 configured to expand in opposite directions, the back pack unit 203 must be opened largely beyond a predetermined angle or the unit 203 must be removed. For example, it is impossible to remove the first control board unit 201. Accordingly, when attention is paid to removing the first control board unit 201, it is difficult to remove 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.

  Next, the back surface structure of the main body frame 12 and the game board 30 is demonstrated. 9 is a rear view showing a configuration in a state in which the game board 30 is assembled to the main body frame 12 and the units 201 to 203 are removed. FIG. 10 is a perspective view of the main body frame 12 as viewed from the rear. FIG. 11 is a perspective view of the game board 30 as viewed from the rear.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 25 from the back side, and a plurality (four in this embodiment) of locking fixtures 211 and 212 provided on the main body frame 12. It is fixed so as not to fall backward. The locking fixtures 211 and 212 can be manually rotated, and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a locked state. The left and right three locking fixtures 211 are L-shaped fittings formed by bending metal pieces, and are configured not to protrude outward from the main body frame 12 when the game board 30 is fixed. Note that the locking fixture 212 at one lower portion is an I-shaped fastener made of synthetic resin.

  The variable display unit 35 disposed at the center of the game board 30 is provided with a synthetic resin frame cover 213 that covers the center frame 43 (see FIG. 4) from the rear side. At the rear end, a symbol display device 41 and a display control device 214 as display control means are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 43 are disposed.

  A collective board unit 215 is provided on the back surface of the game board 30 so as to surround the variable display unit 35. The collective plate unit 215 has a base formed of a synthetic resin such as ABS resin as a thin plate-like frame body, and is attached so that the base surface is in contact with the back surface of the game board 30. The collective board unit 215 is provided with a game ball collecting mechanism for collecting game balls won at various winning ports, a winning detection mechanism for detecting winning of game balls at various winning ports, and the like. .

  The game ball collecting mechanism will be described. Below the collective plate unit 215, a collecting passage corresponding to the game board opening of the general winning port 31, the variable winning device 32, and the operating port 33 and collecting at one place on the downstream side. 216 is formed. Further, a discharge passage board 217 made of synthetic resin such as polycarbonate resin is attached to the main body frame 12 below the game board 30, and the discharge ball is placed on the discharge passage board 217, for example, in a game hall outside the pachinko machine 10. A discharge passage 218 is formed to guide the island facility or the like. Therefore, as illustrated in phantom lines in FIG. 9, all the game balls won in the general winning opening 31 and the like are gathered through the collection passage 216 of the gathering plate unit 215, and the discharge passage 218 of the discharge passage board 217 is further collected. Through the pachinko machine 10. Similarly, the out port 36 leads to the discharge passage 218, and the game ball that has not won any prize opening is also discharged to the outside of the pachinko machine 10 through the discharge passage 218. In the above configuration, with the lower end surface of the game board 30 as a boundary, the collective plate unit 215 (collection passage 216) is provided above, and the discharge passage board 217 (discharge passage 218) is provided below. There is no overlap in the front-rear direction with respect to the game board 30. Therefore, when the game board 30 is removed from the main body frame 12, there is no inconvenience that the discharge passage board 17 prevents the game board from being removed.

  The discharge passage board 217 is disposed on the back side of the upper plate 23 in front of the pachinko machine 10, and a wire, a film, or the like is inserted from a ball discharge port (ball passage rod 138 in FIG. 2) leading to the upper plate 23. An illegal act such as allowing the wire, film, or the like to enter the game area side through the gap between the main body frame 12 and the discharge passage board 217 can be considered. Therefore, in the pachinko machine 10, as shown in FIG. 10, the discharge passage board 217 has a height position corresponding to the upper position of the ball passage rod 138 so as to overlap the main body frame 12 and in front of the pachinko machine 10. An extending plate 219 was provided. Therefore, even if it tries to infiltrate a wire, a film, etc. from the clearance gap between the main body frame 12 and the discharge passage board 217, it will be obstructed by the plate 219, and it will be very difficult to infiltrate a wire, a film, etc. to a game area. Become. As a result, an illegal act such as forcibly opening the variable winning device 32 using a wire, a film, or the like can be prevented.

  Explaining the winning detection mechanism, the collective board unit 215 is provided with a winning port switch 221 at a position corresponding to the general winning port 31 on the front side of the game board 30, and a specific area switch 222 and a position corresponding to the variable winning device 32. A count switch 223 is provided. The specific area switch 222 is a switch for determining that a game ball that has won the variable prize device 32 has entered a specific area.

Double-sided printed circuit board. Hereinafter, the configuration of the front side surface of the main substrate 271a will be described. As shown in FIG. 14, a CPU 501 that performs main control and a plurality of latch circuit ICs 284 that process the data output from the CPU 501 into corresponding signals each time are mounted in a substantially central portion of the main board 271a. Further, connector mounting areas are formed in the upper and lower portions of the main board 271a in the drawing, and connectors 285 for connecting to other boards such as a payout control board are mounted in the areas. In addition, a buffer circuit IC mounting region is formed in the right part of the main substrate 271a in the drawing, and a buffer circuit IC 286 that performs noise removal, waveform shaping, and the like of the input signal is mounted in this region. . However, the connector mounting area has one connector non-mounting area 285a that can be mounted but is not actually mounted. The buffer circuit IC mounting area can be mounted with a buffer circuit IC. There are two buffer circuit IC non-mounting regions 286a that are present but not actually mounted. That is, the broken portion of the electric wiring is formed on the main substrate 271a. Each of these non-mounting areas 285a and 286a is an area for mounting a corresponding electronic component when performing a performance test to be described later. The main board 271a is pre-printed with not only a conductor pattern connecting the mounted electronic components but also a conductor pattern connecting the non-mounting regions 285a and 286a.

  The substrate box 273 includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. A hole is formed in the box cover at a position corresponding to the connector mounting area. That is, a hole is formed in the box cover at a position corresponding to the connector non-mounting area 285a. The box base and the box cover are connected so as not to be unsealed 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. 15 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 stored main substrate 271a or when the main substrate 271a is inspected, the connection between the sealing member into which the locking claw is inserted and the other sealing member is disconnected. To do. 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.

Further, an output port 529 is connected to the image controller 526 via a bus line 531, and a symbol display device 41 is connected to the output side of the output port 529.

  The CPU 521 of the display control device 214 controls the display of the symbol display device 41 based on the symbol display command transmitted from the main control device 271. The ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 is for temporarily storing work data and flags used when the CPU 521 executes various programs. Memory.

  The video RAM 524 is a memory for storing display data displayed on the symbol display device 41, and the display contents of the symbol display device 41 are changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as symbols displayed on the symbol display device 41.

It is displayed on the device 41.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And has. The power supply unit 541 supplies necessary operating power to the main control device 271 and the payout control device 311 through a power supply path (not shown). As its outline, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like. Then, these + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 271 and the payout control device 311. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the CPU 501 of the main control device 271 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. The power failure signal SG1 is output to the main controller 271 and the payout controller 311. Based on the output of the power failure signal SG1, the main control device 271 and the payout control device 311 recognize the occurrence of the power failure and execute the NMI interrupt process. The power supply unit 541 outputs the output of 5 volts, which is the drive voltage of the control system, to a normal value for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain. Therefore, the main control device 271 and the payout control device 311 can normally execute and complete the NMI interrupt processing.

  The RAM erase switch circuit 543 receives a switch signal of the RAM erase switch 323, and outputs a RAM erase signal SG2 for clearing backup data of the main controller 271 and the payout controller 311 in accordance with the state of the switch 323. 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 backup areas 503a and 513a is cleared in the main controller 271 and the payout controller 311.

  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 to which numbers “0” to “9” are attached, and a sub-symbol made of, for example, a diamond-shaped symbol. 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 symbol with the odd number (1, 3, 5, 7, 9) corresponds to the “high probability symbol”, and when a big hit occurs in the high probability symbol, it is one of the big hit states. While shifting to a certain normal jackpot state, it further shifts to a high probability state as a privilege gaming state. The main symbol with an even number (2, 4, 6, 8) corresponds to a “low probability symbol”, and when a big hit occurs in the low probability symbol, it is one of the big hit states and the normal Although it shifts to the super jackpot state which is more advantageous than the jackpot state, it shifts to the normal state without shifting to the high probability state. The high probability state means a state in which the subsequent jackpot probability has increased as an added value after the end of the jackpot state, that is, a so-called probability change state, and the normal state (low probability state) is a game that is not such a high probability state. State. Further, in the first specific lamp unit 47, red is displayed in the case of jackpot that shifts to the high probability state after shifting to the normal jackpot state, and green in the case of jackpot that shifts to the normal state after shifting to the super jackpot state. Is displayed.

  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 first symbol of the upper, middle, and lower levels for each symbol row. Accordingly, 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 the left symbol row → the right symbol row → the middle symbol row, and at the time of the stop, the combination of jackpot symbols (the same main symbol combination in the present embodiment) is placed on one of the effective lines. 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. 26, 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 , 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 counters, 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 including 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 in accordance with 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 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 operating port 33. Two types of values of random numbers that are jackpots are set in a low probability state and a high probability state, and the number of random number values that are jackpots in the low probability state is 2, and the values thereof are “337,673”. The number of random numbers that are jackpots under a high probability state is 10, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601 and 661”.

  The jackpot type counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (ie 49), it returns to 0. In this embodiment, the jackpot type counter C2 determines which jackpot state to shift to and whether to shift to a high probability state after the jackpot state ends, for example, C2 = 0. -24 corresponds to the jackpot that shifts to the high probability state after shifting to the normal jackpot state, and C2 = 25 to 49 corresponds to the jackpot that shifts to the normal state after shifting to the super jackpot state. The jackpot type counter C2 also determines the symbol combination when the first symbol stops changing and the position at which the symbol combination is stopped. In other words, in the present embodiment, five effective lines are set in the symbol display device 41, and ten types of specific symbols (main symbols) are set. Therefore, all patterns are set by 50 counter values. Will be. When C2 = 0 to 24, that is, when the jackpot is shifted to the high probability state after the transition to the normal jackpot state, the combination of the odd-numbered symbols and the position where the combination of the symbols is stopped are determined. . On the other hand, when C2 = 25 to 49, that is, when the jackpot is shifted to the normal state after shifting to the super jackpot state, the combination of the even-numbered symbols and the position where the combination of the symbols 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 determines that the final stop symbol after the occurrence of reach is shifted by one shift before and after the reach symbol, and the final stop symbol after the occurrence of reach. “Reach other than front / rear out” that stops at other than the front and rear of the reach symbol and “complete out” that does not generate reach are selected by lottery. For example, C3 = 0, 1 corresponds to front / rear outreach, and C3 = 2. 21 corresponds to reach other than front / rear disengagement, and C3 = 22 to 238 corresponds to complete disengagement. Note that the reach lottery may be set individually according to the game state, the number of activated 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 the reach type of the first symbol such as so-called normal reach, super reach, premium reach, 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 variation time of the first symbol that is variably displayed on 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, by combining these both variation type counters CS1 and CS2, it is possible to easily realize a wide variety of variation patterns of the first symbol. 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 at the time of determining the variation pattern at the start of switching of the color displayed on the first specific lamp unit 47 and at the start of variation of the first symbol.

  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 lower 3 bits of the R register are 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 in the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach other than the front / rear symbol buffer of the RAM 503, 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 time of starting the 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. For example, the second specific lamp counter C4 is configured 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 ramp random number counter C4 is periodically updated (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 roughly 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. 35 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. 35, in step S901, 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 S902, 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 the present 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 S903, 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). Clear to 0 each. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S904, 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. 36. In step S1001, whether or not the game ball has won the start opening 33 (start winning prize) 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 S1002, 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 S1003 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 S1004, the values of jackpot random number counter C1, jackpot type counter C2 and reach random number counter C3 updated in step S903 are stored in the first area of the free storage area of the reserved ball storage area of 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 the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S1004). 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 a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses). .

  FIG. 37 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 in FIG. 37 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 this predetermined time.

  In the NMI interrupt processing, the used register is saved in the backup area 503a of the RAM 503 in step S1101, and the value of the stack pointer is stored in the backup area 503a in the subsequent step S1102. Further, in step S1103, the power-off occurrence information is set in the backup area 503a, and in step S1104, a power-off notification command indicating that the power has been cut off is transmitted to another control device. In step S1105, 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 S1106, 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. 37 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S1104.

  FIG. 27 is a flowchart showing an example of a main process executed by the CPU 501 in the main controller 271. This main process is started upon 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. In subsequent 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 the 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 occurrence information 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 use 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 final stop 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 processing in the order of the variation pattern command → the left symbol row stop symbol command → the middle symbol row stop symbol command → the right symbol row stop symbol command (i.e. The command is transmitted once every 4 msec), and the final stop 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 the variation type counters CS1 and CS2 are incremented by 1, and when these counter values reach the maximum values (198 and 240 in the present embodiment), the respective values are cleared to 0. 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. 29, 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, the set counter symbols CL, CM, and CR are updated for one set.

  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, in step S308 it is further determined 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. If 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 update processing of the off symbol counters CL, CM, CR, in step S204 in FIG. 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 game state transition process for shifting the game state is executed. Although details will be described later, the gaming state transitions to a jackpot state or a high probability state by this gaming state transition process.

  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 random number counter C4 is acquired and the color switching process displayed on the second specific lamp unit 48 is acquired each time. Is 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 opened for a predetermined time. Although the description is omitted, the second specific ramp random number counter C4 is also updated by the timer interrupt process shown in FIG. 35, 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. Then, 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 the present 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 the variation type counters CS1 and CS2 are incremented by 1, and when these counter values reach the maximum values (198 and 240 in the present embodiment), the respective values are cleared to 0. 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, it is possible to update the random number initial value counter CINI (that is, the initial value of the jackpot random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. 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 the jackpot is currently a big hit. 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. If it is not a big hit, it is determined in step S402 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 mode, the process proceeds to step S403, and it is determined 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. And when the number N of operation reservation balls is 0, this processing is ended as it is.

  If the number of operation hold 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 for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the 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 first symbol variation start process will be described with reference to the flowchart of FIG. 31. In step S501, whether or not the big hit is based on the value of the big hit random number counter C1 stored in the execution area of the reserved ball storage area. Is determined. Whether or not it is a big hit is determined based on the relation between the big hit random number counter value and the gaming state 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 in the low probability state that is the normal state, and “67, 131, 199, in the high probability state. 269, 337, 401, 463, 523, 601 and 661 ”are hit values.

  If it is determined that it is a big hit, a round flag setting process is performed in step S502. The round flag is a flag for determining which jackpot state to shift to when a jackpot occurs. In the round flag setting process, first, in step S601, it is determined whether or not the value of the big hit type counter C2 stored in the execution area of the reserved ball storage area is 25 or more. When the value of the big hit type counter C2 is 25 or more, the process proceeds to step S602, 1 is set in the round flag storage area provided in the RAM 503, and this process is terminated. If the value of the big hit type counter C2 is smaller than 25, 0 is set in the round flag storage area in step S603, and the process is terminated.

  Following the round flag setting process, a state flag setting process is performed in step S503. The state flag is a flag for determining whether or not to shift the gaming state to the high probability state after any jackpot state ends. In the state flag setting process, first, in step S701, it is determined whether or not the value of the big hit type counter C2 stored in the execution area of the reserved ball storage area is smaller than 25. If the value of the big hit type counter C2 is smaller than 25, the process proceeds to step S702, 1 is set in the status flag storage area provided in the RAM 503, and this process is terminated. If the value of the big hit type counter C2 is 25 or more, 0 is set in the state flag storage area in step S703, and the process is terminated.

  Subsequent to the state flag setting process, in step S504, a table corresponding to the value of the jackpot type counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (the value of the jackpot type counter C2 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.

  Next, in step S505, 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 S506 whether or not a 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 this case, in step S507, it is further determined whether or not the front / rear reach is 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 the front / rear outreach has occurred, the process proceeds to step S508, and the left, middle and right outreach symbol counters CL, CM, CR stored in the front / rear outreach symbol buffer of the RAM 503 are set as stop symbol commands. Also, in step S509, 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 S505, 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. 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 S510, 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 S511, 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 S505 and the like.

  If it is neither big hit nor reach, the process proceeds to step S512, and the left, middle, and right out symbol counters CL, CM, CR stored in the complete out symbol buffer of the RAM 503 are set in the stop symbol command. In step S513, 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 S505 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, at the time of reach occurrence, or at the time of no reach occurrence, this processing is terminated.

  Returning to the description of FIG. 30, if step S402 is YES, that is, if the color displayed on the first specific lamp unit 47 is being switched, 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 switching start process, the first flag is set to 0 and the second flag is set to 1 after the switch of the red light source is turned on. Accordingly, 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 repeatedly performed. 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 in which color the switching of the color displayed on the first specific lamp unit 47 is finally stopped 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. Thereafter, 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 checked again, and a jackpot that shifts to a high probability state after the transition to the normal jackpot state occurs in the game time. In the case where the red light source switch is turned on, and a big hit that shifts to the normal state after shifting to the super jackpot state occurs in the game time, the green light source switch is turned on and the game time In the case where no big hit occurs in step 1, 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, the final stop command set for determining the stop symbol is set, and then this processing is ended.

  It should be noted that the stop symbol command, the fluctuation pattern command, the final stop command, etc. set in the first specific lamp unit control process are output to the display control device 214 in the external output process in the normal process of FIG. The display control device 214 determines detailed display contents such as a symbol variation mode based on these commands, 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.

  Next, the gaming state transition processing in step S206 will be described with reference to the flowchart of FIG.

  First, in step S801, it is determined whether or not a big hit has occurred. Specifically, the determination is made based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area and the elapse of the switching display time. If a big hit has not occurred, this process is terminated as it is. If a big hit has occurred, the big hit state process shown in steps S802 to S809 is performed. In the big hit state process, it is determined whether or not the value of the round flag is 1 in step S802. As described above, the round flag is a flag for determining which jackpot state to shift to when a jackpot occurs. When the value of the round flag is 1, the process proceeds to step S803, and 16 is set to the round counter RC provided in the RAM 503. If the value of the round flag is not 1, 12 is set in the round counter RC provided in the RAM 503 in step S804. If the round flag value cannot be recognized as 1 due to noise or the like, a negative determination is made in step S802, and 12 is set in the round counter RC in step S804. The round counter RC is a counter for counting the number of times the large winning opening of the variable winning device 35 is opened. That is, when 1 is set in the round flag, the game shifts to a super jackpot state in which the number of times that the big winning opening is opened is four times that in the case where the round flag is not set.

  In the subsequent step S805, a special winning opening / closing process for opening or closing the special winning opening of the variable winning device 35 is executed. Specifically, first, a process of opening the grand prize opening at the start of the round is performed, and then it is determined whether the maximum opening time of the big prize opening has elapsed or whether a predetermined number of game balls have been won in the big prize opening Process. Then, when any of these conditions is satisfied, a process for closing the special winning opening is performed. After performing the process of closing the big prize opening, in step S806, it is determined whether or not the game ball that won the big prize opening has passed the V zone. This determination is made based on whether or not the specific area switch 222 has detected the passing of the game ball. If it passes through the V zone, the process proceeds to step S807, and 1 is subtracted from the value of the round counter RC. In the subsequent step S808, it is determined whether or not the value of the round counter RC has become 0 as a result of subtracting 1, and if not, the process returns to step S805 to execute the big prize opening / closing process. If it is determined in step S806 that the game ball has not passed through the V zone, or if the value of the round counter RC becomes 0 in step S808, the jackpot that ends the jackpot state in step S809. Perform state termination processing. Therefore, under the big hit state, on the condition that the game ball has passed the V zone, the continuous opening of the big winning opening with the upper limit of the number of times set in the round counter RC is allowed.

  When the big hit state process ends, the state transition process shown in steps S810 to S812 is performed. In step S810, it is determined whether or not the value of the status flag is 1. As described above, the state flag is a flag for determining whether or not to shift the gaming state to the high probability state after any jackpot state ends. If the value of the state flag is 1, the process proceeds to step S811, and the subsequent gaming state is set to a high probability state. On the other hand, if the value of the state flag is not 1, in step S812, the subsequent gaming state is set to a low probability state. If the value of the status flag cannot be recognized as 1 due to the occurrence of noise or the like, a negative determination is made in step S810, and processing in which the subsequent gaming state is set to a low probability state is performed in step S812.

  Here, the relationship between the color switching mode displayed on the first specific lamp unit 47 and the symbol variation display on the symbol display device 41 will be described with reference to FIG. FIG. 38A 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. 38 (b) shows the detailed status of the color switching control displayed on the first specific lamp unit 47. FIG. FIG. 38 shows a pattern in which a jackpot that shifts to a high probability state after shifting to the normal jackpot state does not occur in the previous game round, but occurs in this game round in the other game patterns. The basic mode is the same except that the first and last colors are different.

  First, at the timing of t1, the main controller 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. In addition, 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. After that, 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 the t3 The change display of the middle symbol is stopped at the timing. During this time, the main controller 271 continues the switching control of the color displayed on the first specific lamp unit 47 by turning on / 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 control device 271 determines that the switching display time has elapsed, controls the switch of the green light source of the LED lamp disposed in the first specific lamp unit 47, and further controls the red light source. By turning on the switch, the process of ending the switching of the color displayed on the first specific lamp unit 47 is performed, and a final stop command is output to the display control device 214. Upon receiving this final stop command, the display control device 214 controls display of the symbol display device 41 so that the left, middle, and right symbols are finally stopped and displayed. 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 simultaneously terminated 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. 39 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 S1201, initial setting processing 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 S1202, 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 S1203 to permit RAM access, and an external interrupt vector is set in step S1204.

  Thereafter, data backup processing is executed for the RAM 513 in the CPU 511. That is, in step S1205, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed, and in subsequent step S1206, 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 S1207, a RAM determination value is calculated. In subsequent step S1208, 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. It should be noted 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 513 are correctly stored.

  If the RAM erase switch 323 has been pressed, the process proceeds to a RAM initialization process (steps S1215 to S1218). 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 S1215 to S1218). . That is, in step S1215, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S1216, initialization processing of the RAM 513 is executed. In step S1217, the CPU peripheral device is initialized, and in step S1218, 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 S1209, the stack pointer before the power shutdown is restored, and in step S1210, the information on the occurrence of power shutdown is cleared. In step S1211, the CPU peripheral device is initialized, and in step S1212, the register used is restored from the backup area 513a of the RAM 513. Further, in steps S1213 and S1214, 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 the payout control process will be described with reference to the flowchart of FIG.

  In FIG. 40, in step S1301, a command from the main controller 271 is acquired, and the total number of prize balls is stored. In step S1302, launch permission is set for launch control apparatus 312. In step S1303, 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 S1304, setting of the lower plate full state or the lower plate full state is performed according to the change in the state of the lower plate 16. That is, when the lower pan 16 is determined to be full 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 S1305, setting of a tank ball absence state or a tank ball absence release state is executed according to 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. When there is no tank ball, the tank ball no state setting is executed. Perform configuration.

  Thereafter, in step S1306, the presence / absence of a state to be notified is determined.

  In steps S1307 to S1309, prize ball payout processing is executed. In this case, if the prize ball is not payable and the total number of prize balls stored in step S1301 is not 0 (both NO in steps S1307 and S1308), the process proceeds to step S1309, 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 S1307 and S1308), the process proceeds to the lending / dispensing process in steps S1310 to S1312.

  In the rental ball payout process, if the rental ball payout is not possible and a rental ball payout request is received from the card unit (NO in step S1310, YES in step S1311), the process proceeds to step S1312, and is shown in FIG. The ball rental control process described later is started. Further, if a rental ball cannot be dispensed or a rental ball dispensing request has not been received (YES in step S1310 or NO in step S1311), subsequent ball removal processing is executed.

  In step S1313, 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 the subsequent step S1314, the control of the vibrator 360 (vibration motor control) is executed on the condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  Here, in the prize ball control process shown in FIG. 41, in step S1401, the payout motor 358a is driven to execute the prize ball payout. In the subsequent step S1402, 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 advances to step S1403 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 S1404, 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 advances to step S1405 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 advances to step S1406 to determine 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 S1407, and then the process returns to the payout control process in FIG.

  In the ball lending control process shown in FIG. 42, in step S1501, the payout motor 358a is driven to pay out a lending ball. In the subsequent step S1502, 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 proceeds to step S1503, where the payout motor 358a is driven to execute the retry process and the stop process of the payout motor 358a is executed, and then 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 S1504 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 S1505 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.

  Further, if the game ball count is normal, the process proceeds to step S1506, and 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, a stop process of the payout motor 358a is executed in step S1507, and then the process returns to the payout control process of FIG.

  Next, a configuration for performing a performance test of the pachinko machine 10 will be described.

  FIG. 43 is a schematic configuration diagram showing a test apparatus during a performance test. When performing the performance test, as shown in FIG. 43, the main board 271a of the pachinko machine 10 and the test relay terminal plate 561 are connected through electrical wiring such as a harness, and the test relay terminal plate 561 and the performance test are performed. The machine 600 is connected through electrical wiring such as a harness. As described above, the connector non-mounting area 285a and the buffer circuit non-mounting area 286a are provided on the front side surface of the main board 271a (see FIG. 14). When performing a performance test, first, buffer circuits IC551, 552 and a test connector 553 are mounted in each of these non-mounting regions 285a, 286a, and the test relay terminal plate 561 is input via the test connector 553. Connect to connector 562. Here, the test relay terminal plate 561 is for processing the data signal output from the main board 271a, and the performance tester 600 is the data signal output from the test relay terminal plate 561. Based on this, the performance data of the pachinko machine 10 is obtained. In FIG. 43, a description has been given of a configuration in which one test connector 553 is mounted on the main board 271a, and one data output connector 563 is mounted on the test relay terminal plate 561. Street. That is, one test connector 553 having 40 output terminals is mounted on the main board 271a. The test relay terminal plate 561 is equipped with four data output connectors 563 having 68 output terminals. This is because the performance testing machine 600 is equipped with four connectors having 68 input terminals, and the test relay terminal plate 561 is required to have the same connector.

  FIG. 44 is a block diagram showing an electrical configuration of the main board 271a. Detection signals from various devices and various switches are input to the input connector 549 of the main board 271a. Specifically, the RAM erasing signal SG2 is output from the power supply device 313, the detection signal SG3 such as a prize ball counting signal or a payout abnormality signal is output from the payout control device 311, and the operating port switch 224 is operated from the operating port. A winning signal SG4 is output, a detection signal SG5 such as a general winning signal or a through gate passing signal is output from the board relay board 226, and a detection signal SG6 such as a specific area passing signal or a count signal is output from the large winning opening relay board 227. Is output. Each of these detection signals SG2 to SG6 is taken into the CPU 501 via the corresponding comparator 550. The comparator 550 is configured to output a corresponding detection signal when the input level of the detection signal is smaller than a predetermined threshold voltage. Although illustration is omitted, when there are a plurality of types of detection signals to be output, such as the payout control device 313, signal lines and comparators 550 are provided as many as the types. The detection signals SG2 to SG6 output from the comparator 550 are input to the CPU 501 and one buffer circuit IC552 mounted on the main board 271a during the performance test. The buffer circuit IC552 performs noise removal, waveform shaping, and the like of the detection signals SG2 to SG6, and then outputs the detection signals SG2 to SG6 to the test connector 553, that is, the test relay terminal plate 561.

  Based on the detection signals SG2 to SG6 output from the comparator 550, the CPU 501 performs processing relating to the game, such as first specific lamp unit control processing, for example, and for example, variation pattern command data and stop symbols generated as a result of the processing. Data relating to the game such as command data is output as data signals DA0 to DA7. Incidentally, the signal line for transmitting the data signals DA0 to DA7 is constituted by a bus (common transmission path) that transmits signals from a plurality of signal sources and can be transmitted to others. Further, the CPU 501 applies one of the preset chip select signals CSSG1 and CSSG2 to one buffer circuit IC552 mounted on the main board 271a during the performance test in accordance with the output of the data signals DA0 to DA7. Outputs ON. The chip select signals CSSG1 and CSSG2 are signals for selecting an electronic circuit to function. Therefore, in this embodiment, the data signals DA0 to DA7 output using the eight signal lines can have a plurality of types of meaning as data relating to the game. Therefore, the number of buffer circuits IC and signal lines mounted on the main board 271a and the number of output terminals of the test connector 553 can be reduced. The buffer circuit IC 552 performs noise removal, waveform shaping, and the like of the chip select signals CSSG1 and CSSG2, and then outputs the chip select signals CSSG1 and CSSG2 to the test connector 553, that is, the test relay terminal plate 561. Incidentally, a chip select signal is preset in the CPU 501 in addition to the two types described above. However, since the other chip select signal is output to a latch circuit IC 284 described later, description thereof will be omitted.

  Data signals DA0 to DA7 output from the CPU 501 are input to the buffer circuit IC286. The buffer circuit IC286 performs noise removal, waveform shaping, and the like of the data signals DA0 to DA7, and then each data signal DA0 to the latch circuit IC284 and the other buffer circuit IC551 mounted on the main board 271a during the performance test. ~ DA7 is output. The latch circuit IC 284 processes the input data signals DA0 to DA7 into a command corresponding signal corresponding to, for example, a stop symbol command, and outputs it to another control device such as the display control device 214. The buffer circuit IC551 performs noise removal and waveform shaping of the data signals DA0 to DA7 again, and then outputs the data signals DA0 to DA7 to the test connector 553, that is, the test relay terminal plate 561.

  FIG. 45 is a block diagram showing an electrical configuration of the test relay terminal plate 561. An output signal from the main controller 271 (main board 271a) is input to the input connector 562 of the test relay terminal plate 561. That is, data signals DA0 to DA7, chip select signals CSSG1 and CSSG2, and detection signals SG2 to SG6 are input.

  The data signals DA0 to DA7 output from the main board 271a are input to the latch circuit IC564 and the latch circuit IC565, the chip select signal CSSG1 is input to the latch circuit IC564, and the chip select signal CSSG2 is input to the latch circuit IC565. Here, the latch circuit IC will be briefly described. In this embodiment, a D flip-flop circuit (for example, 74HC273) is used as the latch circuit IC. In the latch circuit IC, a chip select signal is input to the clock terminal CK and a data signal is input to the data terminal D. If the data signal when the chip select signal enters the clock terminal CK is an ON signal, an ON signal is output from the output terminal Q, and the data signal when the chip select signal enters the clock terminal CK is an OFF signal. The ON signal is continuously output from the output terminal Q until it is discriminated. For example, as shown in FIG. 46, when the data signal DA0 is the ON signal when the chip select signal CSSG1 is input to the clock terminal CK of the latch circuit IC564 at the timing t1, the ON signal is output as the data signal DB0. The ON output of the data signal DB0 is continuously held until the data signal DA0 when the chip select signal CSSG1 is input to the clock terminal CK of the latch circuit IC564 is determined to be an OFF signal. That is, at the timing t2, since the data signal DA0 is the ON signal at the timing when the chip select signal CSSG1 is input, the data signal DB0 also remains the ON signal. At the subsequent timing t3, the data signal DA0 is turned off at the timing when the chip select signal CSSG1 is input, so the data signal DB0 is switched to the OFF signal. Note that the latch circuit ICs used in the present embodiment (including the latch circuit IC mounted on the main board 271a) are all driven on the same operation principle.

  The latch circuit IC564 processes the data signals DA0 to DA7 using the chip select signal CSSG1 as a clock and outputs the processed data signals DB0 to DB7 to the latch circuit IC566 and the latch circuit IC567. The latch circuit IC565 processes the data signals DA0 and DA1 using the chip select signal CSSG2 as a clock, and outputs the processed signals to the latch circuit IC566 or the latch circuit IC567 as chip select signals CSSG3 and CSSG4. The subsequent latch circuit IC 566 processes the data signals DB0 to DB7 using the chip select signal CSSG3 as a clock, and outputs the data signals DC0 to DC7 to the data output connector 563, that is, the performance tester 600. Similarly, the latch circuit IC567 processes the data signals DB0 to DB7 using the chip select signal CSSG4 as a clock, and outputs the data signals DD0 to DD7 to the data output connector 563, that is, the performance tester 600.

  The detection signals SG2 to SG6 output from the main board 271a are input to the buffer circuit IC 568. After the noise removal and waveform shaping are performed in the buffer circuit 568, the data output connector 563, that is, a performance test is performed. Output to the machine 600. That is, the detection signals SG2 to SG6 are output to the performance tester 600 without being processed.

  Here, as a specific example, a case will be described in which a game ball passes through the operation port 33 and the first symbol performs variable display. However, descriptions of buffer circuits IC and the like that are not involved in data signal processing will be omitted. When the game ball passes through the operation port 33, the detection signal SG4 is output from the operation port switch 224 to the CPU 501 of the main board 271a. With the reception of the detection signal SG4, the CPU 501 outputs data such as a stop symbol command and a variation pattern command to the latch circuit IC284 and the test relay terminal plate 561 as data signals. The latch circuit IC 284 mounted on the main board 271a processes the data signal to generate a command corresponding signal corresponding to the stop symbol command or the variation pattern command, and outputs it to the display control device 214. In the test relay terminal board 561, the latch circuit IC 564 first processes the data signal to generate a command corresponding signal corresponding to the stop symbol command or variation pattern command, and the latch circuit IC 566, 567 further stops the symbol command or variation. The command corresponding signal corresponding to the pattern command is processed, and the information on the symbol to be finally stopped and the information on the variation pattern are generated and output to the performance tester 600. In addition, since the detection signal SG4 is also output to the performance tester 600 without being processed, the variation of the first pattern is started on the condition of the detection signal from the operation port switch 224, and It can be confirmed by the performance tester 600 that the change of the symbol corresponding to the result determined by the CPU 501 is performed.

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

  The data signals DA0 to DA7 output from the CPU 501 of the main board 271a are processed by the test relay terminal board 561 and then output to the performance tester 600, whereby various performance data are output to the performance tester 600. It becomes possible to acquire suitably. This is because the performance data to be acquired may be acquired by processing the data signals DA0 to DA7 on the test relay terminal board 561. When acquiring performance data with the performance tester 600, the main board 271a and the performance tester 600 are connected without using the test relay terminal board 561, and the data signals DA0 to DA7 are processed with the performance tester 600. It is also possible to acquire performance data. However, in such a configuration, it is necessary to prepare a performance tester 600 having different processing capabilities for each model of the pachinko machine 10, and the cost required for the performance test becomes great. It is also possible to acquire the performance data by outputting the data signal processed by the latch circuit IC 284 of the main board 271a to the performance tester 600. However, in such a configuration, performance data directly connected to the processing performed in the main control device 271 can be acquired. However, for example, in the main control device 271 such as data indicating that the first symbol is variably displayed. It is not possible to acquire non-directly connected performance data that is not directly connected to the processing to be performed. In addition, when the CPU 501 is configured to perform processing for outputting data signals related to non-directly connected performance data, it is necessary to perform the processing even when a game is actually being performed other than the performance test. The load will increase. That is, by applying the present invention, it is possible to acquire arbitrary performance data without changing the specifications of the pachinko machine 10 and the performance tester 600.

  In general, the performance test is requested by a third party. The control content of the main board 271a is greatly related to the profit on the player side or the game hall side where the pachinko machine is installed, and if the pachinko machine 10 does not operate properly, the profit on the player side or the game hall side is significant. It will be inhibited. For example, if a big win is not opened despite the occurrence of a jackpot, the player's profit will be hindered. As a result, the profit on the game hall side will be hindered. Therefore, it is confirmed whether the pachinko machine 10 operates properly not by the manufacturer that manufactured the pachinko machine 10 but by a third party organization. In such a case, when performing the performance test of the pachinko machine 10, it is necessary to configure the pachinko machine 10 so that the information signal required from the performance tester 600 can be output on the pachinko machine 10 side. It is necessary to prepare a corresponding number of output connectors. However, by adopting a configuration in which the test relay terminal plate 561 is connected between the pachinko machine 10 and the performance tester 600, the specifications of the pachinko machine 10 (more specifically, the main board 271a) are made to correspond to the performance tester 600. Since it is not necessary, a performance test can be suitably performed.

  By providing the test relay terminal plate 561 separately from the main board 271a, the cost of the pachinko machine 10 can be reduced. This is because when the electronic component such as the latch circuit IC 564 mounted on the test relay terminal plate 561 is mounted on the main board 271a, the cost of the main board 271a increases. In addition, it is possible to suppress an increase in size of the main substrate 271a. This is because when the electronic component mounted on the test relay terminal plate 561 is configured to be mounted on the main board 271a, it is necessary to increase the area of the main board 271a. The size of the pachinko machine 10 is almost limited by the size of the outer frame 11, and in the configuration in which various members are disposed within the range of the outer frame 11, increasing the area of the main board 271a This is a great problem in relation to the arrangement space. Such a problem can surely be avoided if electronic components are mounted on both sides of the main board 271a. However, this causes a new problem that it is difficult to detect an illegal act on the main board 271a.

  A performance test can be suitably performed by printing a conductor pattern for performance test in advance. Certainly, it is also possible to prepare a test main board on which a conductive pattern for performance testing is printed, and perform the performance test by mounting electronic components such as the CPU 501 on the test main board. However, when a performance test is performed using the test main board, the main board 271a mounted on the pachinko machine 10 that is actually sold differs from the main board used for the performance test. The meaning of what it does will be lost. This is because there is no guarantee that the acquired performance data is the performance data of the pachinko machine 10 that is actually sold. Furthermore, it is possible to perform performance tests by mounting electronic components such as CPUs prepared exclusively for performance tests on main boards prepared for performance tests. Since the guarantee which is the performance data of the machine 10 is completely lost, not only the meaning of performing the performance test but also the value is lost. Further, by providing the connector non-mounting area 285a and the buffer circuit IC non-mounting area 286a, when preparing the pachinko machine 10 for performance test, the electronic components corresponding to the non-mounting areas 285a and 286a are mounted. For example, the pachinko machine 10 for sale that is not subjected to a performance test need not be mounted, so that the cost of the pachinko machine 10 can be reduced. Further, for example, it is possible to prevent an illegal act of misusing the output terminal of the test connector 553 such that the CPU 501 is erroneously operated by inputting a predetermined signal from the output terminal of the test connector 553 to the CPU 501.

  A configuration in which the signal levels of the detection signals SG2 to SG6 output from various switches or the like are compared with a predetermined threshold voltage by the comparator 500, and when the threshold level is lower than the threshold voltage, the CPU 501 and the buffer circuit IC552 are turned ON. By doing so, it becomes possible to suppress variations in the signal level of the detection signals SG2 to SG6 due to noise or the like, and it is possible to output a stable signal to the CPU 501 and the buffer circuit IC 552 (performance tester 600). . Therefore, it is possible to prevent the CPU 501 and the performance tester 600 of the main board 271a from malfunctioning due to noise or the like. Further, it is possible to avoid a problem that a mismatch occurs between the detection signal level input to the CPU 501 and the detection signal level input to the performance tester 600.

  By configuring the data signals DA0 to DA7 and the chip select signals CSSG1 and CSSG2 from the CPU 501 to the buffer circuits IC551 and 552, it is possible to prevent the performance tester 600 from malfunctioning due to noise or the like, for example. It becomes.

  By configuring the data signals DA0 to DA7 from the CPU 501 to the buffer circuit IC286, it is possible to prevent other control devices such as the display control device 214 and the performance tester 600 from malfunctioning due to, for example, noise. It becomes possible. Further, by providing the buffer circuit IC 286, it is possible to prevent an illegal act of inputting an unauthorized signal to the CPU 501 from a conductor pattern (that is, a disconnected portion) that communicates with the buffer circuit IC non-mounting area 286a. Become.

  By adopting a configuration in which the data signals DA0 to DA7 processed by the test relay terminal plate 561 and the chip select signals CSSG1 and CSSG2 and the detection signals SG2 to SG6 that are not processed are input to separate buffer circuits IC552 and 553. Further, it is possible to relax the restrictions on the arrangement received by the signal lines (buses) that transmit the data signals DA0 to DA7, and it is possible to make the electrical wiring such as the conductor pattern relatively simple.

  With the configuration in which the detection signals SG2 to SG6 are output to the performance tester 600 without being processed, the performance tester 600 indicates that the CPU 501 of the main board 271a is operating due to detection of various switches. Can be confirmed.

  By adopting a configuration in which the chip select signals CSSG1 and CSSG2 are output from the CPU 501 of the main board 271a, it is desired to output a variety of data signals to the performance tester 600, thereby reducing the number of data signals to be output at a time. At the same time, the electrical wiring can be used efficiently. This is because it is possible to give a plurality of types of meaning to the data signal output from one electric wiring. In this configuration, it is difficult to continuously output one data signal from the main board 271a. However, the data signal is processed using the latch circuit ICs 564 to 567 in the test relay terminal plate 561. Thus, even if one data signal is intermittently output from the main board 271a, it can be processed into a continuous information signal by the test relay terminal board 561, so that arbitrary test information can be sent to the performance test apparatus 600. Can be obtained.

  The latch circuit IC of the test relay terminal board 561 is configured to output a chip select signal, whereby a plurality of types of test information can be obtained based on one data signal output from the CPU 501 of the main board 271a. It becomes.

  A hole is formed in the board box 273 when a gaming machine for performing a performance confirmation test is prepared by forming a hole in a position corresponding to the connector non-mounting region 285a in the box cover of the board box 273. It is possible to mount the test output connector 553 without performing a forming operation or the like. In addition, the performance check test can be performed in a state where the main board 271a is accommodated in the board box 273, that is, in a state substantially equal to the state in which the pachinko machine 10 is actually operated. For example, the main board 271a is accommodated in the board box 273. It is possible to obtain various performance data such as noise cutoff characteristics associated with the performance.

  When it is determined that a big hit is made in the first symbol variation start process, the game state to be transferred is set to a noise or the like by setting the round flag and the state flag based on the value of the big hit type counter C2. It is possible to suppress changes due to the occurrence. Even if the value of the jackpot type counter C2 cannot be accurately determined due to the occurrence of noise or the like, whether or not to shift to the jackpot state to be shifted to a high probability state is determined by the determination result of the round flag and the state flag. It is because it is made based on. Further, by setting the round flag and the status flag individually, even if noise or the like occurs, it is possible to increase the possibility that at least one of the value of the big hit type counter C2, the round flag, and the status flag can be accurately determined. It becomes possible. Therefore, it is possible to suitably suppress a change in the gaming state to be transferred due to the occurrence of noise or the like.

  In the first symbol variation start process, that is, when the first symbol variation display (switching display of the first specific lamp unit 47) is started, the round flag and the state flag are set, thereby varying the display. Even if noise or the like occurs after the start of, it is possible to increase the possibility that at least one of the round flag and the status flag can be accurately determined. Therefore, it is possible to suitably suppress the change of the gaming state to be transferred due to the occurrence of noise or the like. Furthermore, a configuration in which a round flag and a status flag are set when each counter value is stored in the start winning process is certainly possible. However, in such a configuration, it is necessary to provide a round flag storage area and a status flag storage area in each area of the reserved ball storage area, which causes a problem that the storage capacity of the RAM 503 increases. Also, for example, when the start winning process is performed during the variation display of the first symbol, noise or the like may occur before the variation display based on the process is performed, and any value may not be accurately determined. is there. If any of the values cannot be accurately determined, there is a discrepancy that, for example, the combination of the high-probability symbols is displayed as a final stop, but the transition to the normal jackpot state is not performed and the high-probability state is not performed. Will occur. On the other hand, in this embodiment, the start winning process is performed during the fluctuation display of the first symbol, and noise or the like is generated until the fluctuation display based on the process is performed, so that the value of the big hit type counter C2 is accurately determined. Even if it becomes impossible, since the symbol that is finally stopped and displayed based on the determination result, the jackpot state to be transferred, and whether or not to shift to the high probability state are set, the mismatch does not occur.

  In the jackpot state process and the state transition process, if the round flag and the state flag value cannot be recognized as 1, the configuration is such that a negative determination is made, and an illegal act that intentionally generates noise or the like from the outside of the gaming machine. It becomes possible to prevent.

  When a big hit occurs, the combination of the same symbols is stopped and displayed on the display screen of the symbol display device 41, and a specific color (red or green) is stopped and displayed in the first specific lamp unit 47. By displaying the color continuously until the next game round, the display control device 214 is illegally operated, and the display screen is displayed as if a jackpot has been generated. Even if a fraudulent act in which the mouth switch 221 or the specific area switch 222 is fraudulent to cause a large amount of game balls to be paid out is not displayed on the first specific lamp unit 47, the game hall Employees can detect the above-mentioned fraudulent behavior quickly and reliably. Furthermore, if it is attempted to prevent the above fraud from being detected by employees of the game hall, etc., it is necessary to carry out fraud not only to the display control device 214 but also to the first specific lamp unit 47. It becomes troublesome for the actor who performs, and the said fraudulent act can be suppressed.

  Further, the main control device 271 that generally manages the progress of the game is difficult to perform fraud due to the presence of the sealing unit 319, etc., and the first specific lamp unit 47 is directly controlled by the main control device 271. Therefore, the reliability of the display mode in the first specific lamp unit 47 can be improved.

  In addition, an LED lamp is disposed in the first specific lamp unit 47, and the game result in the first specific lamp unit 47 can be taught by performing on / off control of the light source switch of the LED lamp. By doing so, the control regarding the 1st specific lamp part 47 by the main-control apparatus 271 can be simplified. Therefore, the above effect can be obtained without increasing the processing load of the main controller 271.

  The display switching of the display color of the first specific lamp unit 47 is started together with the start of the symbol variation display on the display screen of the symbol display device 41, and is stopped and displayed after the symbol variation display is finished. Therefore, the player can visually recognize the variable display of the symbols on the display screen and increase the expectation for occurrence of the big hit from the aspect as usual. If the display color switching display of the first specific lamp unit 47 is stopped before the symbols variably displayed on the display screen are stopped, the player is stopped and displayed on the first specific lamp unit 47. This is because the game result can be determined by the color.

  For example, when a failure or the like occurs in the display control device 214, there is a possibility that the display screen of the symbol display device 41 may display a display different from the actual result of the big win lottery in the main control device 271. In this case, in a configuration in which there is no display unit that is directly displayed and controlled by the main control device 271 such as the first specific lamp unit 47, it cannot be determined whether the display content of the symbol display device 41 is correct. On the other hand, according to the present embodiment, the result of the big hit lottery in the main controller 271 is directly displayed on the first specific lamp unit 47, so that the display content of the first specific lamp unit 47 is visually recognized. Thus, it is possible to clearly determine whether the display content of the symbol display device 41 is correct. As a result, confusion when the above situation occurs can be suppressed.

  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 buffer circuit 286 is provided on the output side of the CPU 501 of the main board 271a. However, in addition to this, a buffer circuit may be provided on the input side of the CPU 501. With this configuration, the detection signals SG2 to SG6 can be stably supplied to the CPU 501, and malfunction of the CPU 501 can be suppressed. It is also possible to suppress fraudulent acts performed from the input side of the CPU 501.

  (B) In the above embodiment, the CPU 501 outputs a chip select signal, so that eight data signals can have a maximum of 16 meanings. However, the chip select signal cannot be output. Alternatively, 16 data signals may be output, or more chip select signals may be output to reduce the number of data signals output at a time.

  (C) In the above embodiment, when performing a performance test, two buffer circuits are mounted on the front side surface of the main board 271a, and data signals DA0 to DA7 are processed by the test relay terminal board 561; Although the detection signals SG2 to SG6 and the chip select signals CSSG1 and CSSG2 that are not processed by the test relay terminal plate 561 are input to separate buffer circuits, they may be input to the same buffer circuit. Further, the number of buffer circuits to be mounted when performing the performance test is arbitrary.

  (D) In the above embodiment, two types of chip select signals CSSG3 and CSSG4 are output from the latch circuit 565 of the test relay terminal plate 561. However, three or more types of chip select signals may be output. Good. In such a configuration, if the number of latch circuits mounted is increased, the performance tester 600 can acquire more performance data. Incidentally, seven latch circuits are mounted on the actual test relay terminal board, and the latch circuit 565 outputs five types of chip select signals using five types of data signals. In other words, a maximum of 40 types of performance data can be output to the performance tester 600.

  (E) In the above embodiment, by outputting the chip select signals CSSG1 and CSSG2 from the CPU 501 of the main board 271a, it is possible to selectively use signals transmitted through the same signal line and output them at a time. However, the present invention is not limited to such a configuration. For example, a configuration using a sub-address may be used. In other words, any configuration that can output many types of data signals with a small number of signal lines is sufficient.

  (F) In the above embodiment, the data signal processed by the latch circuit 284 of the main board 271a is not output to the test connector 553, but it goes without saying that the data signal may be output. Further, when the data signal processed by the latch circuit 284 is configured to be output to the test connector 553, the detection signals SG2 to SG6 that are not processed by the test relay terminal plate 561 are output to the buffer circuit 552. It is desirable to do. This is because the data signal has already been processed by the latch circuit 284, so that the necessity of processing by the test relay terminal board 561 is scarce.

  (G) In the above embodiment, the special gaming state has two types of normal jackpot state and super jackpot state, and the bonus gaming state has one type of high probability state, but is limited to this configuration. Instead, a configuration in which one type of special gaming state is provided and a plurality of privilege gaming states may be provided. For example, as a plurality of types of privilege gaming states, a high probability state in which the jackpot probability is increased, and the switching time of the second specific lamp unit 48 is shortened, thereby increasing the chance of opening the electric accessory attached to the operation port 33. It is set as the structure provided with a switching shortening state. Moreover, the structure provided with two or more special game states and privilege game states may be sufficient, and the kind provided is not restricted to two types, Three or more types may be sufficient. Even if it is in these structures, there exists an effect similar to the said embodiment.

  (H) In the above embodiment, one type of the high probability state is provided as the privilege gaming state, and it is determined whether to shift to the high probability state based on the determination result of the state flag. It is good also as a structure which is provided with a privilege game state and always transfers to any privilege game state after completion | finish of a jackpot state. Or it is good also as a structure which is provided with a some privilege game state and determines whether it transfers to a privilege game state and which privilege game state to transfer based on the discrimination | determination result of a state flag. Even if it is in these structures, there exists an effect similar to the said embodiment.

  (I) In the above embodiment, when a jackpot is generated with a high probability symbol, the transition is made to a high probability state after shifting to a normal jackpot state, and when a jackpot occurs with a low probability symbol, the transition is made to a super jackpot state. Although the configuration does not shift to the high probability state, the configuration is changed. That is, when a jackpot occurs with a high probability symbol, the transition to a high probability state occurs after transitioning to a super jackpot state, and when a jackpot occurs with a low probability symbol, the transition does not transition to a high probability state after transitioning to a normal jackpot state And In such a configuration, the player's advantage varies greatly depending on which symbol the jackpot is generated. Therefore, if the value of the jackpot type counter C2 changes due to the occurrence of noise or the like, the player Alternatively, one of the game halls where the gaming machines are installed suffers an excessive disadvantage. However, if the round flag and the status flag are separately set in the configuration, the disadvantage can be suppressed.

  (J) In the above embodiment, a pachinko machine is described that shifts to a jackpot state as a special gaming state when a jackpot occurs, and then transitions to a high probability state as a special gaming state. It is good also as a structure which transfers to a some privilege game state continuously. For example, after the end of the big hit state, the state shifts to the high probability state until the first symbol variation display (switching display of the first specific lamp unit 47) is performed a predetermined number of times (for example, seven times), and the high probability state ends. The first symbol variation display (switching display of the first specific lamp unit 47) is shifted to the switching shortened state until a predetermined number of times (for example, 50 times) is performed. Even in such a configuration, when it is determined that a big hit is made in the first symbol variation start process, the round flag, the status flag, and the switch shortening flag are individually set based on the value of the big hit type counter C2. As a result, the same operational effects as those of the above-described embodiment can be obtained.

  (K) In the above embodiment, the round flag and the status flag are set to 0 or 1. However, the present invention is not limited to this configuration. For example, 0 or 55H may be set. Good. Even in such a configuration, in the round flag determination process (step S802) and the state flag determination process (step S810), if each flag value is not 55H, it is determined that the value is 0. It is possible to achieve the same effect as the form.

  (L) In the above-described embodiment, the combination of the symbol that has been displayed in the final stop and the jackpot state to be transferred and the presence / absence of the shift to the high probability state are uniquely associated. It may be. That is, it is good also as a structure which a player cannot recognize from the combination of the 1st symbol by which the last stop display was carried out, and the presence or absence of the transition to the big hit state and high probability state.

  (M) In the above embodiment, the main control device 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 determines whether the jackpot that shifts to the high probability state after shifting to the normal jackpot state, the jackpot that shifts to the normal state after shifting to the super jackpot state, or no jackpot occurrence occurs in the game time. A display command including whether it occurs and the color switching display time displayed on the first specific lamp unit 47 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, it is possible to further reduce the processing load of the main control device 271 while achieving the effects of the above embodiment.

  (N) In the above embodiment, the first specific lamp portion 47 is disposed above the display screen of the symbol display device 41. However, the first specific lamp portion 47 is disposed at another position. Also good. For example, the 1st specific lamp part 47 may be the structure arrange | positioned in the out port 36 vicinity.

  (O) In the above embodiment, after all the symbols on the display screen of the symbol display device 41 are stopped, the switching display of the color displayed on the first specific lamp unit 47 is ended. The configuration may be such that the switching display of the colors displayed on the first specific lamp unit 47 ends at the same time as all the symbols on the display screen 41 stop.

  (P) In the above-described embodiment, the display of the color displayed on the first specific lamp unit 47 is performed by repeatedly displaying the order of red, green, and blue, but this is changed. Also good. For example, the above three colors may be displayed at random.

  (Q) In the above embodiment, the first specific lamp unit 47 is provided separately from the symbol display device 41 that performs variable display of the first symbol. However, the first specific lamp unit 47 may not be provided.

  (R) In the above-described embodiment, the pachinko machine 10 having a relatively large gaming area compared to the conventional one has been described. It can also be applied to. Also, other types of pachinko machines different from the above-described embodiment, for example, so-called type 2 pachinko machines that release a predetermined number of times when a game ball enters a specific area of a special device, or a specific area of a special device The game can be applied to a so-called third-class pachinko machine that generates a big hit when a game ball enters, a pachinko machine equipped with other accessories, an arrange ball machine, a sparrow ball, and the like. In addition, non-ballistic gaming machines, for example, revolving type gaming machines such as slot machines, and belts with symbols are circulated by operating the start lever after inserting the gaming balls, and the circulatory motion is stopped. It can also be applied to a ball-type belt-type game machine that is stopped by a button, and award balls are paid out by a combination of the stopped symbols.
