The ball release lever 19 is provided with a biasing member such as a coil spring that biases the ball removal lever 19 toward the side where the ball removal hole is closed. When the operation of the ball removal lever 19 is released, The closing plate is returned to the opening position of the ball hole by the urging force. A speaker cover portion 15b in which a large number of small holes are gathered is formed at a position different from the ball outlet 15a of the back wall panel 15, and a speaker 20 (see FIG. 3) installed behind the back wall panel 15 is formed. ) Is emitted forward through the speaker cover portion 15b.

  As shown in FIG. 2, the ashtray 21 is provided in the base part 11 to the left of the bulging part 11a. The ashtray 21 is attached so as to be able to be reversed to the lower side on the near side so as to easily remove the butts and the like accumulated inside, and faces the base portion 11 on the right side and the back side. Although a specific illustration is omitted, a support shaft for cantilevering the ashtray 21 in a rotatable state is provided on the right side surface of the ashtray 21, and the ashtray 21 is located upward on the back as shown in the figure. A locking portion that is locked to the base portion 11 is provided at a position that is open to the bottom.

  Most of the front plate 9 described above is formed of ABS resin in the same manner as the main body frame 5. The front plate 9 is exposed on the front side of the pachinko machine 1, but by molding with ABS resin, it is possible to plate appropriate portions of the surface for the purpose of decoration or the like. In addition, because the ashtray 21 is disposed in the vicinity, flame retardant ABS resin is used for the parts constituting the lower tray 13 and the back wall panel 15, and it becomes difficult to burn even if tobacco is accidentally placed. It is preferable to configure as described above.

  A front door frame 8 as a front door is provided in a range excluding the front plate 9 on the front side of the main body frame 5 so as to cover the main body frame 5. According to this configuration, the entire front side of the main body frame 5 is covered by the front plate 9 and the front door frame 8. Like the front plate 9, the front door frame 8 is formed of ABS resin and is attached to the main body frame 5 so as to be openable and closable. That is, similarly to the main body frame 5, the opening / closing axis extending vertically to the left side when viewed from the front of the pachinko machine 1 can be opened to the front side as an axis. The front door frame 8 is exposed on the front side of the pachinko machine 1, but by molding with ABS resin, it is possible to plate appropriate portions of the surface for the purpose of decoration or the like. .

  As shown in FIG. 1, a bulging portion 22 bulging toward the near side above the lower plate 13 is provided at a lower position of the front door frame 8, and an upper opening is provided inside the bulging portion 22. A dish 23 is provided. The upper plate 23 is a ball receiving tray for temporarily storing game balls paid out from a payout device to be described later and guiding them to the game ball launching device side while aligning them in a line. A ball removal lever 24 for the upper plate 23 is provided on the front surface side of the bulging portion 22, and when this ball removal lever 24 is operated, a ball removal passage (not shown) provided near the most downstream portion of the upper plate 23. ) Is opened, and the stored balls in the upper plate 23 are discharged to the lower plate 13. Similarly to the lower plate 13 and the like, the upper plate 23 can be made of flame-retardant ABS resin.

  In this pachinko machine 1, 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 this configuration), 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 8, and the upper plate 23 is provided integrally with the front door frame 8. In this case, since the glass door frame and the front decoration frame are integrated into the front door frame 8, the strength of the glass support structure can be improved in the front door frame 8. In this pachinko machine 1, for the purpose of extending the game area, a large glass 29 is mounted on the front door frame 8 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, it is possible to ensure sufficient strength of the glass support structure by providing a frame portion integrated with the upper plate below the glass. it can. The vertical and horizontal dimensions of the glass 29 are generally 405 mm × 405 mm, whereas the pachinko machine 1 uses 453 mm × 434 mm.

  The front door frame 8 is extended downward so as not to interfere with the game ball launching handle 7 at least when opening and closing. Specifically, the dimension La from the lower end of the pachinko machine to the lower end of the front door frame 8 is, for example, about 201 mm in one existing model, whereas in this pachinko machine 1, it is about 30 mm smaller, about 172 mm. It has become. In addition, 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, is about 261 mm in the present pachinko machine 1. Here, by lowering the position of the upper plate 23, the vertical distance from the tip of the nozzle of a ball lending device (not shown) arranged side by side on the left side of the pachinko machine 1 in the game hall is increased. Although there is a concern about spillage or the like, in this configuration, a 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, which is a rental ball discharge portion from the nozzle. Thereby, even if it is the structure which lowered the position of the top plate 23, inconveniences, such as a fall 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 this configuration.

  In the front door frame 8, 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 described later, etc.) ) 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 3 toward the front side is limited to 45 to 50 mm.

  As shown in FIG. 3, the main body frame 5 is mainly composed of a resin base 25 whose outer shape is substantially the same as that of the outer frame 3, and a substantially circular window hole 26 is formed at the center of the resin base 25. The game board 30 is detachably attached to 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. The game board 30 is attached from the back of the pachinko machine 1, and only the substantially central portion of the front surface of the game board 30 is exposed to the front side of the main body frame 5 through the window hole 26 of the resin base 25. The game board 30 has a length in the vertical direction of 476 mm and a length in the horizontal direction of 452 mm, as in the prior art.

  Next, the structure of the game board 30 is demonstrated based on FIG.

  The gaming board 30 is formed with a plurality of large and small openings penetrating in the front-rear direction by router processing, and each opening has a general winning port 31, a variable winning device 32, an operating port 33, a through gate 34, and a variable display. A unit 35 and the like are provided. The general winning port 31, the variable winning device 32, the operating port 33, the through gate 34, the variable display unit 35, and the like are attached to the surface of the game board with wood screws or the like. In this configuration, the variable display unit 35 is disposed at the approximate 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. Further, through gates 34 are arranged on both 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 described later, and a predetermined value is set for the upper plate 23 (in some cases, the lower plate 13) based on the detection result. A number of prize balls will be paid out. In addition, an out port 36 is provided at the lowermost part of the game board 30, and game balls that have not entered various winning ports etc. are guided through the out port 36 toward a ball discharge path (not shown). It is like that. 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, it is easier to form the out port (in FIG. 4, since the rail unit 50 is provided on the front side, the out port 36 is closed). Shown in state). The game board 30 is provided with a large number of nails and various members (functions) such as a windmill 37 in order to appropriately distribute and adjust the falling direction of the game balls.

  On the left and right sides of the game board 30, a plurality of notches 38 are formed as recesses so as to avoid interference with the protruding areas from the left and right sides of the body frame 5 that is the assembly partner.

  As described above, in the pachinko machine 1, 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 lowered. 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 is provided with a notch corresponding to the game ball inlet. Although it was necessary, in this pachinko machine 1, the game ball intake port and the game board 30 do not overlap each other by lowering the game ball intake port. Is not required. Therefore, it becomes an advantageous structure in the game board 30 manufacturing process.

  The variable display unit 35 is provided with a first symbol display device 41 that variably displays a first symbol (special symbol) triggered by winning in the operating port 33, and around the first symbol display device 41. A center frame 43 is disposed so as to surround it. A holding lamp 44 corresponding to the first symbol display device 41 is provided on the center frame 43. The number of times that the game ball has passed through the operating port 33 is held up to a maximum of 4 times, and the number of the held balls is displayed by turning on the holding lamp 44. The hold lamp 44 may be configured to be variably displayed on a part of the first symbol display device 41. The first symbol display device 41 constitutes a “pattern display device” for variably displaying a pattern.

  A second symbol display device 42 that variably displays a second symbol (ordinary symbol) with the passage of the through gate 34 as a trigger is provided at the upper center of the center frame 43. A holding lamp 46 corresponding to the second symbol display device 42 is provided at the lower part of 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. The hold lamp 46 may be configured to be variably displayed on a part of the first symbol display device 41, like the hold lamp 44.

  The 1st symbol display apparatus 41 is comprised as a liquid crystal display device provided with the comparatively large liquid crystal display of 8-inch size, for example, and the display content is controlled by the display control apparatus mentioned later. On the first 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. This first symbol display device 41 is provided with a liquid crystal display of a 10-inch size or 7-inch size other than the 8-inch size, a device with a wide-size display, or a CRT, a dot matrix, a 7-segment, etc. The display screen may be configured according to the type.

  The 2nd symbol display apparatus 42 is provided with the display part 45 which displays 2 types of 2nd symbols, for example, "(circle)" and "x". When the game ball passes through the through gate 34, the display symbol (second symbol) of the display unit 45 fluctuates, and when the variable display stops at a predetermined symbol (for example, “◯” symbol), the operation port 33 The electric accessory attached to is configured to be open for a predetermined time. Specifically, when the game ball passes through the through gate 34, each LED built in the back of the portion to which the display of “◯” and “×” is given turns on alternately, and finally “○ Only “LED” corresponding to one of “” and “×” is lit. The display unit 45 is configured to be variably displayed on a part of the first symbol display device 41 (liquid crystal display device) in addition to a configuration to be variably displayed by alternately lighting a plurality of lamps (LEDs). Also good.

  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 in a predetermined open state in which the game ball is easy to win in a special game state (hereinafter referred to as “hit”). It can be switched.

  More specifically, when a game ball wins in the operation port 33, the first symbol display device 41 variably displays the first symbol, and the final symbol after the stop is a combination of specific symbols set in advance. Will occur. Once the jackpot is generated, the variable winning device 32 is in a predetermined open state, and the game ball is likely to win. As an opening mode of the variable winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winnings is defined as one round, and the winning at the continuous winning port in the variable winning device 32 is a condition. In general, the condition for shifting to the next round is satisfied, and the variable prize-winning device 32 is repeatedly opened up to a plurality of rounds (for example, 15 rounds) as an upper limit.

  In addition, a rail unit 50 is attached to the game board 30 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, so that the game ball launching handle 7 can be rotated. Along with this, the launched game ball is guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product, and more specifically, a fluorine-containing polycarbonate resin is used to reduce frictional resistance.

  This rail unit 50 has an inner rail portion 51 and an outer rail portion 52 that are provided in an inner and outer double, and the inner rail portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion. The rail portion 52 is formed in a substantially semicircular shape so as to surround the upper open region of the inner rail portion 51 and to be parallel to the left side portion of the inner rail portion 51.

  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. Similarly to the inner rail portion 51, the outer rail portion 52 has a support portion 52 a that is integrally formed with other resin portions and is provided to stand substantially vertically on the surface of the game board 30. A sliding plate 52b for smoother flight of the game ball is attached to the inner surface of the portion 52a. 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. A guide rail is formed by the inner rail portion 51 and the outer rail portion 52, and a ball guide passage is formed by a portion where the rail portions 51 and 52 face each other at a predetermined interval. In the part where the inner and outer rail parts 51 and 52 face each other, the rail parts 51 and 52 are connected by the contact part 53 with the game board 30, and the ball guide passage is formed in a groove shape opened to the front side. Yes.

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

  A substantially arc-shaped flange 56 is formed on the outer periphery of the rail unit 50 so as to project outward. The flange 56 constitutes an attachment portion of the rail unit 50 to 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 the state thereof Thus, the rail unit 50 is fastened to the game board 30 by inserting screws or the like through the plurality of through holes formed in the flange 56. 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 flange 56 is 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 1, that is, the game area on the game board 30 can be expanded. It has become. The rail unit 50 is disposed so that the position of the maximum gaming area on the game board 30 reaches the left and right end positions of the game board 30. Among the parts corresponding to the ball guide passages of the rail unit 50, particularly with respect to the receiving part of the game ball, the flange 56 of the corresponding part is firmly attached so that the rail unit 50 is firmly attached and the flying of the game ball is stabilized. It is screwed at more points than the others (three in this configuration, and 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 the foul ball that flows backward in the ball guide passage without reaching the game area is used as a foul ball passage 76 (see FIG. 3). Has a guiding function. The lower right corner and the lower left corner of the game board 30 are spaces (Sa, Sb in the figure) for sticking seals or plates such as certificate papers, and in order to secure this adhesive space, notches are formed in the flange 56. 58a and 58b are formed. 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 on the front side of the pachinko machine 1.

  Next, the game area will be described. The board surface of the game board 30 is divided into inner and outer areas by rail units 50 (inner and outer rail parts 51 and 52), and an inner area divided into a substantially circular shape is a game area. In particular, in this configuration, the game area divided on the board surface of the game board 30 is configured to be much larger than the conventional one. That is, in this configuration, 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 outer rail portion 52 to the extreme right position of the inner rail portion 51. 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 this configuration, the game area is a region surrounded by the inner rail portion 51 and the outer rail portion 52 when viewed from the front of the pachinko machine 1, except for the region of the ball guide passage that is the opposite portion of the inner and outer rail portions 51, 52. This will be described as a region. In other words, since the game area does not include the ball guide path portion, the left limit position toward the game area is specified by the inner rail portion 51, not by 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 this configuration, 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 game area is desirably 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. About the combination of the said width | variety and height, it can be set as the thing which combined the said numerical value arbitrarily. If the width or height of the game area exceeds a certain value, it is conceivable that a part of the game area may exceed the board surface of the game board 30, but other members are provided along the game board surface for the area beyond that. What is necessary is just to supplement by.

  In the above configuration, 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. Since the area ratio of the game area to the surface of the game board 30 has been only about 50% in the past, the game board 30 having the same size as the conventional one is used as in this configuration. It can be said that the game area has been expanded. The external shape of the pachinko machine 1 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 game with respect to the game board 30 surface as described above. Increasing the area ratio by about 20% is very significant from the viewpoint of expanding the game 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 configuration, 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 a corner (for example, a lower right corner or an upper right corner) is expanded.

  Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 1 is about 40%, which is a much larger area ratio than in the past. The area ratio of the game area to the area of the front side of the entire pachinko machine 1 is desirably 35% or more. Of course, it may be 40 percent or more, 45 percent or more, or 50 percent 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 through 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. Moreover, even if a relatively large variable display unit 35 is provided in the center of the game area by extending the game area in the left-right direction, through gates 34, windmills 37, a plurality of Nails (guide nails such as a triangular nail for guiding a game ball to the center), other objects, etc. can be provided with a margin, and games in the game areas on the left and right sides of the variable display unit 35 can be provided. Without making the flow of the ball monotonous, the behavior of the game ball can be fully enjoyed.

  As shown in 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 launch rail 61 is fixedly attached to the resin base 25 via a metal plate 62 behind the launch rail 61, and is configured to extend linearly at a predetermined launch angle (launch angle). According to this, the game ball launched in accordance with the turning operation of the game ball launch handle 7 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path. In this configuration, as described above, since the curvature of the ball guide passage is reduced because the game area is greatly expanded as compared with the prior art, a device for stabilizing the launch ball is required. Therefore, the launch position of the game ball is lowered so that the tilt angle (launch angle) of the launch rail 61 is somewhat larger than the existing one (that is, the launch rail 61 is raised), and the launch rail 61 is made to be a game ball. By forming the launching device 61 so as to extend from the launching position of the launching device to a position exceeding the center position (out port 36) of the game area, the length of the launching rail 61 is made longer than the existing one, and a sufficiently long ball The guidance distance is secured. According to this, the game ball launched from the game ball launcher can be guided to the ball guide passage in a more stable state. In addition, the metal plate 62 on which the launch rail 61 is installed is enlarged, and the metal plate 62 is screwed at a number of locations (15 to 20 locations in the present configuration), so that the launch rail 61 is strong against the game board 30. According to this, the ball can be more stabilized than the conventional one.

  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 is discharged to the lower blood 13 through the foul ball passage 76. Is done. In this configuration, the length of the firing rail 61 is about 240 mm, and the length of the gap (the length on the extension line of the firing rail 61) leading to the foul ball passage 76 at the tip of the firing 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. There is something that rampages in the ball guide passage and jumps 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. According to this, 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, game balls are supplied to the game ball launching device one by one from the ball outlet on the front door frame 8 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 configuration, the drop from the exit of the ball on the front door frame 8 side to the launch position becomes large. Since the guide members 63 and 64 are respectively provided on the side, the game ball supplied from the ball outlet on the front door frame 8 side is always set at a predetermined launch position, and a stable launch operation can be realized. The game ball launching device is provided with a hitting ball cage 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 hit ball rod. Yes. Therefore, by changing the material to light metal such as aluminum and reducing the size of the spear shaft, the hitting spear head portion (proximal end) is used to reduce the weight of the hitting spear while ensuring sufficient firing force. A weight portion is formed on the tip portion on the opposite side of the head. According to this, sufficient and stable launching 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 up or caught, and the strength of the hitting ball can be easily adjusted.

  As shown in FIG. 3, 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 5. A game ball guide unit 70 for guiding the ball to either the upper plate 23 or the lower plate 13 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 5, and the 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 so that the inside can be visually recognized by a transparent resin material such as polycarbonate resin, and the front frame 8 is closed between the main frame 5 and the front door frame 8 with the front frame 8 closed. It is formed so as to be relatively thin so as to fit in between. The game ball guide unit 70 is integrally formed with the above-described foul ball passage 76 and a ball discharge passage 71 for communicating the discharge ports 66 and 67 with the lower tray 13. In this 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 5, and an opening / closing plate 73 is attached so as to close the communication port 72. It has been. 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 this configuration, in a state where the front door frame 8 is opened, the opening / closing plate 73 rises as shown in the figure by the biasing force of the spring 75 and closes the communication port 72. In this state, the game ball discharged from the first discharge port 66 is guided to the lower plate 13 through the ball discharge passage 71. Therefore, when the front door frame 8 is opened in a state where the game balls are stored upstream of the communication port 72, the stored balls are not spilled from the communication port 72 and pass through the ball discharge passage 71. To flow down. That is, even in the present pachinko machine 1 in which the front decorative frame is omitted and the upper plate 23 is directly provided on the front door frame 8, the front door frame 8 is opened on the upstream side of the communication opening 72. Inconveniences such as spilling a game ball can be prevented.

  On the other hand, when the front door frame 8 is closed, the opening / closing plate 73 is pushed open against the urging force of the spring 75 by the ball passage rod 138 (see FIG. 2) provided on the back surface of the front door frame 8. It is done. 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. On the downstream side of the ball discharge passage 71 of the game ball guide unit 70, a lower plate full tank switch for detecting that the game ball discharged to the lower plate 13 is full (full) is attached.

  As shown in FIG. 3, the resin base 25 is provided with a small rectangular window 78 in 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.

A front door frame opening switch 27 for detecting the open state of the front door frame 8 is provided on the upper portion 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 8 is closed with respect to the main body frame 5, the front door frame opening switch 27 is pushed into the front door frame. 8 is detected, and in a state where the front door frame 8 is opened with respect to the main body frame 5, the pin returns to the protruding position and the opening of the front door frame 8 is detected. When the front door frame 8 is closed with respect to the main body frame 5, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 8) on the back of the front door frame 8, Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 5 side for grounding. Therefore, the metal fittings on the back surface of the front door frame 8 are conducted to the locking device and the hinge metal fitting on the main body frame 5 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge metal 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 5 as a support mechanism for supporting the front door frame 8 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. A specific configuration of the front door frame 8 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 surface side of the front door frame 8 is inserted into the right end side (the side opposite to the opening / closing axis) of the main body frame 5. Insertion holes 87 and 88 are provided, respectively. In this pachinko machine 1, a locking device for locking the main body frame 5 and the front door frame 8 is hidden behind the main body frame 5, and the metal fittings 155 and 156 are inserted through the insertion holes 87 and 88. The front door frame 8 is locked to the main body frame 5 so as not to be opened by being locked by the locking device.

  A cylinder lock 91 is installed at the lower right corner of the body frame 5 as a key member for locking and unlocking the body frame 5 with respect to the outer frame 3 and locking and unlocking the front door frame 8 with respect to the body frame 5. 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 5. 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 5 and the locking and unlocking of the front door frame 8, and when the key inserted into the keyhole is turned counterclockwise (counterclockwise direction) When the key is unlocked and the key is turned to the right (clockwise direction), the front door frame 8 is unlocked.

  As shown in FIG. 2, a vertically long cover member 92 is attached to the main body frame 5 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 and lower ends thereof, and the upper locking portion is locked to the main body frame 5 side, and The cover member 92 is attached to the main body frame 5 by sandwiching the engaging portion on the side between the main body frame 5 and the front plate 9.

  The front door frame 8 has a notch 145 formed in accordance with the shape of the cover member 92. When the front door frame 8 is closed, the front door frame 8 and the cover member 92 constitute the front portion of the pachinko machine. To do. When the front door frame 8 is closed, the collar portion formed on the cover member 92 is pressed by the front door frame 8, and rattling of the cover member 92 is prevented.

  Next, the front door frame 8 will be described. FIG. 5 is a rear view of the front door frame 8. The front door frame 8 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 elliptical shape close to a circular shape, and has a substantially central portion on the left and right sides curved more gently than the upper and lower sides. The substantially central portion may have a linear shape. Above the window part 101 of the front door frame 8, the frame width of the narrowest part is about 61 mm. In this configuration, the frame width dimension 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 5 in the main body frame 5 and is about 85 mm to 95 mm. This is significantly shorter than conventional models with a frame width of. Thereby, the visibility of the upper area in the game area can be easily ensured, and the large-sized variable display unit 35 can be disposed 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 8 are restricted in reducing the frame width, and need a width dimension sufficient to ensure the strength of the front door frame 8 itself and the glass support strength. In this configuration, the frame width of the narrowest part in each of the left and right frame parts is about 44 mm. In this case, since the game area is greatly expanded in the pachinko machine 1, the frame width of the front door frame 8 is about 44 mm as described above on the left side when viewed from the front of the pachinko machine 1, 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 5 is about 21 mm, and the latter dimension is considerably small. That is, in this configuration, in a state where the front door frame 8 is closed, a part of the ball guide passage overlaps and is covered with the left frame portion of the front door frame 8. However, even if it becomes difficult to visually recognize the game ball in the ball guide passage, this ball guide passage is only a passing area until the game ball is guided to the game area, and the game where the player mainly enjoys the game. The game ball is not difficult to see in the area. Therefore, there is no trouble in actual game. As described above, it is possible to expand the game area without affecting the game while ensuring sufficient strength and glass support strength of the front door frame 8.

  Small windows 107 to which a transparent resin is attached are provided on the left and right sides of the lower end portion of the front door frame 8 so that a part of the surface of the main body frame 5 and the surface of the game board 30 (including a certificate paper) can be visually recognized. . The transparent resin attached to the small window 107 is formed in a flat shape so that the inside certificate paper or the like can be easily read by a machine or the like. The small window 107 can be provided with a magnifying lens part so that the hall operator or the like can easily see the internal certificate paper or the like.

  The front door frame 8 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, as shown in FIG. 1, an annular illumination part 102 containing a light emitting means such as an LED is provided symmetrically along the periphery of the window part 101, and the pachinko machine 1 is located at the center of the annular illumination part 102. A central illumination part 103 having a built-in light emitting means such as an LED is provided at the uppermost part. In this pachinko machine 1, the central illumination unit 103 functions as a jackpot lamp, and notifies that the jackpot is being hit by performing lighting or blinking in the jackpot state. Further, around the upper plate 23, there is also provided an upper plate illumination unit 104 that also incorporates light emitting means such as LEDs. In addition, on the left and right sides of the central illumination unit 103, there are 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 is composed of an inner / outer double resin cover layer and a light emitting body (LED) with a launch plate housed inside thereof, and the inner side surface of each resin cover layer is in a direction intersecting vertically and horizontally in each layer. A protrusion (or a wave-like protrusion) is provided on the surface. 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 illumination in a state where it is dispersed in a large number or with a three-dimensional 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 8 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and confirmation of the card frequency can be performed by the ball lending operation unit 120 in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 1. 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 lent directly from the ball lending device or the like to the upper plate without using a card unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is given to. Thereby, in the configuration of the present pachinko machine 1 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.

  As shown in FIG. 5, various reinforcing members 131 to 134 made of metal are provided on the back side of the front door frame 8 so as to surround the window portion 101, and these reinforcing plates 131 to 134 are provided on the back side of the front door frame 8. Therefore, it is attached to 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.

  The reinforcing plate 131 on the opening and closing axis side which is the right side of FIG. 5 is provided with an assembly fitting 151 as an assembly mechanism for the support fittings 81 and 82 (see FIG. 3) on the main body frame 5 at the upper and lower ends. 152 is attached. 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 on the main body frame 5 side is inserted into the shaft hole, while the upper mounting bracket By inserting the shaft portion 151 into the support hole 83 of the upper support fitting 81 on the main body frame 5 side, the front door frame 8 is supported to be openable and closable with respect to the main body frame 5. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof, and this engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, the front door frame 8 is configured in a form including the upper plate 23, and even in the pachinko machine 1 in which the upper and lower shaft support intervals are increased, the front door frame 8 can be prevented from being lifted at the intermediate position. Unauthorized acts and the like floating the front door frame 8 are suppressed.

  A pair of upper and lower hook metal fittings 155 and 156 having a hook shape are attached to the reinforcing plate 132 opposite to the opening / closing axis line on the left side of FIG. These metal fittings 155 and 156 extend rearward and are provided corresponding to insertion holes 87 and 88 (see FIG. 3) provided in the main body frame 5. When the front door frame 8 is closed with respect to the main body frame 5, the metal fittings 155 and 156 are inserted into the insertion holes 87 and 88 on the main body frame 5 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 the 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 when the front door frame 8 is closed, the side wall of the launch rail 61 is formed, and game balls may spill forward from the launch rail 61. Is not configured.

  As shown in FIG. 5, a ball passage rod 138 is installed at the rear portion of the lower reinforcing plate 134 toward the rear of the pachinko machine 1, and at least above the ball passage rod 138, Similarly, a collar portion 139 extending toward the rear of the pachinko machine 1 is provided. In a state where the front door frame 8 is closed on the main body frame 5 side, a protrusion extending along the upper side of the communication port 72 on the main body frame 5 side is inserted between the ball passage bar 138 and the bar part 139. The According to this, even if a wire or film is infiltrated from the ball passage 138 and it is attempted to cheat, it becomes difficult to infiltrate the wire or film into the game area. As a result, the wire or film is It is possible to prevent fraudulent acts that are used.

  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 29 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 29 is attached to the front and back at predetermined intervals.

  As described above, in the pachinko machine 1 configured as described above, since the game area is expanded, the ball guide passage formed between the inner and outer rail portions 51 and 52 is in a state where the front door frame 8 is closed. Is partially covered by the front door frame 8. For this reason, in the ball guide passage, a portion where the open portion on the near side cannot be covered with the glass 29 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 path, or the outer rail portion 52 and the glass 29. There is a risk of being caught in a gap formed between the two. In order to solve this problem, in this configuration, a rail cover 140 is attached to the front door frame 8 to cover the front side opening 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 of the window portion 101. It has become. 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 8), a portion where the ball guide passage protrudes from the side edge portion of the glass 29 is provided. A covering portion 141 for covering is provided. According to the configuration of the rail cover 140 described above, when the front door frame 8 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage. Generation | occurrence | production of the malfunction that it jumps out or a game ball is pinched | interposed into the clearance gap formed between the outer rail part 52 and the glass 29 can be prevented.

  Further, on the lower back side of the rail cover 140, a ridge 142 that extends in an arc shape along the inner edge and protrudes rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 8 is closed. Therefore, for example, even if an attempt is made to cheat by infiltrating a wire or film from the gap between the front door frame 8 and the main body frame 5, the wire or film is allowed to enter the game area inside the ball guide passage. It 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 region of the inner edge of the rail cover 140. According to this configuration, it is difficult to infiltrate a wire, a film, or the like in a wider range. It is possible to more surely prevent fraudulent acts that are performed using film or film.

  Next, the configuration of the back surface of the pachinko machine 1 will be described with reference to FIGS.

  The overall outline of the back configuration of the pachinko machine 1 will be described. On the back side of the pachinko machine 1, various control devices (various control boards) are arranged so as to be arranged vertically and horizontally or stacked one after another. In addition, a game ball supply device (payout mechanism) for supplying game balls, a protective cover made of resin, and the like are attached. In this configuration, various control devices are divided and mounted on two mounting bases to form two control board units 201 and 202, and these control board units 201 and 202, and the back pack unit 203 are individually provided as main bodies. It is attached to the back of the frame 5 or the game board 30. In this case, the first control board unit 201 unitizes the main control device 271 (main board) and the audio lamp control device 272 (audio lamp control board), and the second control board unit 202 sets the payout control device 311 (payout). Control board), launch control device 312 (launch control board), and power supply device 313 (power supply board) are unitized, and the back pack unit 203 is configured by uniting a payout mechanism and a protective cover. This is because the resin portion such as the payout mechanism and the protective cover is generally called a back pack. 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 so as to be detachable without using any tools or the like on a unit basis, and a main shaft frame 5 is provided with a support shaft part in part. 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. As shown in the schematic diagram of FIG. 8, the first control board unit 201 having a substantially L shape is arranged at the approximate center of the pachinko machine 1, the second control board unit 202 is arranged below the first control board unit 201, and the back pack unit 203. Are arranged in a region partially overlapping with the first control board unit 201.

  As shown in FIG. 8, the first control board unit 201 is provided with a support shaft portion M1 at the left end portion when viewed from the back of the pachinko machine 1, and the first control board unit 201 is formed by the support shaft portion M1. It can be rotated around the axis A. 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 is locked to the upper end portion. A claw portion M3 is provided, and the first control board unit 201 is held along the back surface of the pachinko machine 1 main body by the fastening portion M2 and the locking claw portion M3.

  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 1, and the second control board unit 202 can be rotated around the axis B by the support shaft part M4. ing. The second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like on the left end thereof, that is, on the open end side opposite to the support shaft part M4. The fastening portion M5 holds the pachinko machine 1 along the back surface thereof. The back pack unit 203 is provided with a support shaft portion M6 at the right end when viewed from the back of the pachinko machine 1, and the back pack unit 203 is rotatable about an axis C by the support shaft portion 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 1 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 1. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3 and rotating the unit 201 around the axis A, Lift in condition. Thereby, if there is no backpack 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 development directions of the units 201 to 203 are not the same, and the first control board unit 201 opens to the left as viewed from the back of the pachinko machine 1, whereas the second control board unit 202 and the back pack unit. 203 is configured to open to the right. In this case, since the first control board unit 201 is partially overlapped with the back pack unit 203, it is impossible to remove the first control board unit 201 without opening the back pack unit 203. Furthermore, since the first control board unit 201 and the back pack unit 203 are each configured to expand in the opposite direction, the back pack unit 203 must be opened largely beyond a predetermined angle or removed. For example, the first control board unit 201 cannot be removed.

  Therefore, 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 5 is opened with respect to the outer frame 3 by operating the key 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 5 and the game board 30 is demonstrated.

  FIG. 9 is a rear view showing a configuration in which the game board 30 is assembled to the main body frame 5 and the units 201 to 203 are removed. FIG. 10 is a perspective view of the main body frame 5 as viewed from the rear. FIG. 3 is a perspective view of the game board 30 as viewed from the rear.

Through the pachinko machine 1. Similarly, the out port 36 communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 1 through the discharge passage 218. In the above configuration, with the lower end surface of the game board 30 as a boundary, the collecting plate unit 215 (collection passage 216) is provided above, and the discharge passage board 217 (discharge passage 218) is provided below. 217 does not overlap with the game board 30 in the front-rear direction. Therefore, when the game board 30 is removed from the main body frame 5, there is no inconvenience that the discharge passage board 217 hinders the removal of the game board.

  The discharge passage board 217 is disposed on the back side of the upper plate 23 in front of the pachinko machine 1, and a wire, a film, or the like is inserted from a ball discharge port (ball passage rod 138 in FIG. 2) reaching the upper plate 23, and further the wire. It is conceivable to carry out an illegal act such as causing a film or the like to enter the game area side through a gap between the main body frame 5 and the discharge passage board 217. Therefore, in the present pachinko machine 1, 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 and is placed in front of the pachinko machine 1 so as to overlap the main body frame 5. An extending plate 219 was provided. Therefore, even if it tries to infiltrate a wire, a film, etc. from the gap between the main body frame 5 and the discharge passage board 217, it is obstructed by the plate 219, and it is very difficult to infiltrate the wire, the film, etc. to the game area. Become. As a result, it is possible to prevent an illegal act such as forcibly opening the variable winning device 32 using a wire, a film or the like.

  Explaining the winning detection mechanism, as shown in FIG. 9, the collective board unit 215 is provided with a winning opening switch 221 at a position corresponding to the general winning opening 31 on the front side of the game board 30, and corresponds to the variable winning apparatus 32.

Is output. Then, a predetermined number of game balls are paid out by the output of the payout control device 311. Here, in the conventional so-called evidence ball system, the game balls won in various winning openings are once collected in a winning ball processing device, and the winning ball processing device confirms the presence of the winning balls one by one and then pays out. However, in the pachinko machine 1 configured as described above, since the winning of the game ball is electrically detected for each winning opening and the payout is immediately performed, there is a large amount of game balls to be paid out. However, the payout can be carried out quickly, and the winning ball processing apparatus is not required.

  The collective board unit 215 is provided with a board external terminal board 230 at the upper right part thereof. The panel external terminal plate 230 has an output terminal for outputting a signal every time the variation of the first symbol is stopped (determined), and an output terminal for outputting a signal during the big hit or during the reduction of the variation time of the first symbol.

Since this back pack unit 203 stores a large amount of game balls in the upper part, the fixtures 241 and 242 for supporting the upper part of the back pack unit 203 may have a particularly strong strength. Desirably, a rotating fixture is used in this configuration.

  As described above, a long bearing fitting 235 is provided on the left and right sides (the right side in FIG. 9) of the main body frame 5, while the left and right other sides (the left side in FIG. 9) of the main body frame 5 are provided. A locking device is provided. The locking device includes a base frame 247 that extends in the vertical direction and is fixed to the main body frame 5, and a long interlocking rod 248 that is assembled to the base frame 247 so as to be movable in the vertical direction. The cylinder lock 91 is integrated with a lower portion of 247. The interlocking rod 248 moves in either the up or down direction by operating the cylinder lock 91. The interlocking bar 248 is provided with a pair of upper and lower bar brackets 249 having a hook shape. When the main body frame 5 is closed with respect to the outer frame 3, the bar bracket 249 is attached to the support bracket ( (Not shown) and locked by a locking device. In this case, when the interlocking rod 248 moves upward by the operation of the cylinder lock 91, the locking of the main body frame 5 with respect to the outer frame 3 is released, and conversely, the interlocking rod 248 moves downward by the operation of the cylinder lock 91. Then, the locking of the front door frame 8 with respect to the main body frame 5 is released.

  In the above-described configuration in which the bearing bracket 235 and the locking device (base frame 247, interlocking rod 248, etc.) are distributed to the left and right sides of the main body frame 5, the bearing bracket 235 and the locking device (base frame 247, interlocking rod 248, etc.) are provided. The game board 30 is attached to the main body frame 5 so as to have a width that leaves a region for placement. As a result, the game area can be expanded.

  In the lower right part of the game board 30 on the back surface of the main body frame 5, there is provided a game ball distribution unit 245 for distributing a game ball paid out by a payout mechanism, which will be described later, to any of the upper plate 23, the lower plate 13, or the discharge passage 218. It has been. In the game ball distribution unit 245, the left opening 245a communicates with the upper plate 23 through the first discharge port 66, the central opening 245b communicates with the lower plate 13 through the second discharge port 67, and the right Each passage is formed so that the opening 245c communicates with the discharge passage 218. The game ball distribution unit 245 is firmly attached to the main body frame 5 with screws or the like. Therefore, the floating at the installation site of the game ball distributing unit 245 is prevented, and an illegal act caused by intruding a wire, a film, or the like from the gap can be prevented. A synthetic resin speaker box 246 is attached to the lower end portion of the main body frame 5 to surround the back of the speaker 20 installed on the back side of the back wall panel 15, and the speaker box 246 allows the speaker sound to escape backward. The sound quality is improved in the low frequency range by functioning in such a way as not to occur.

  Next, the configuration of the first control board unit 201 will be described. 13 is a front view of the first control board unit 201, FIG. 14 is a perspective view of the unit 201, FIG. 15 is an exploded perspective view of the unit 201, and FIG. 16 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 includes a mounting base 251 having a substantially L shape, and the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251. The main control device 271 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and random numbers used in various lotteries. A main substrate including a generator, a clock pulse generation circuit used for time counting and synchronization, etc. is provided, and this main substrate is accommodated in a substrate box 273 as an encapsulating means made of a transparent resin material or the like. Has been configured.

  The substrate box 273 includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other so as not to be opened by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

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

  The sound lamp control device 272 includes, for example, a CPU for controlling sound and lamp display in accordance with instructions from the main control device 271 or the display control device 214, and a sound lamp control board including ROM, RAM, various ports, and the like. The sound lamp control board is housed in a board box 275 made of a transparent resin material or the like. A power relay board 276 is mounted on the sound lamp control device 272, and power of the power supply device 313 is supplied to the display control device 214 and the sound lamp control device 272 via the power relay board 276.

  The mounting base 251 is made of a synthetic resin such as a polycarbonate resin, and is colored opaque, for example, green or blue. However, the mounting base 251 may be colorless and transparent or translucent. Two substrate mounting surfaces 252 and 253 having a flat shape are provided on the surface of the mounting base 251. These substrate mounting surfaces 252 and 253 extend in a direction orthogonal to the length and breadth, and are formed with a step in the front-rear direction. Standing portions 254 erected from the substrate mounting surface 252 are integrally formed on the upper edge portion and the lower edge portion of the substrate mounting surface 252, respectively. A main controller 271 is disposed on the horizontally long substrate mounting surface 252, and an audio lamp controller 272 is disposed on the vertically long substrate mounting surface 253. At this time, the upper and lower sides of main controller 271 are supported by upright portions 254. The sound lamp control device 272 is fixed to the substrate mounting surface 253 with screws or the like at a plurality of locations.

  Here, as shown in FIGS. 15 and 16, the substrate mounting surface 252 is formed with horizontally elongated through holes 256 at two positions on the left and right. On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally-operated fixtures 277 at two positions on the left and right sides of the back surface thereof. When the main controller 271 is mounted on the board mounting surface 252, the main control board (main controller) 271 is placed so that the fixture 277 is inserted into the through hole 256 of the board mounting surface 252. The main controller 271 is locked by rotating the fixing tool 277 in the state. Therefore, the main control device 271 cannot be removed unless the lock 277 is unlocked from the back side of the first control board unit 201, so that a deterrent effect such as board removal is obtained.

  In addition, in the mounting base 251, a shielding portion 257 for shielding an opening leading to the back space of the substrate mounting surface 252 is provided below the substrate mounting surface 252 for the main substrate. Accordingly, it is possible to prevent a hand or the like from being inserted into the back surface of the mounting base 251 from below the substrate mounting surface 252 so that the locked state of the fixture 277 cannot be illegally released. Further, when the first control board unit 201 is mounted on the back surface of the pachinko machine 1, the upper portion of the unit 201 is covered with the back pack unit 203, so that it is also prevented that a hand or the like is inserted into the back surface of the mounting base 251. The locked state of the fixture 277 cannot be illegally released.

  As described above, the first control board unit 201 cannot be removed unless the back pack unit 203 is opened at a predetermined angle or larger, or the unit 203 is not removed. The backpack unit 203 cannot be opened unless the main body frame 5 is opened with respect to the outer frame 3 by key operation. That is, if the main body frame 5 cannot be opened, the first control board unit 201 cannot be rotated or removed as a result, and the main controller 271 cannot be removed. Therefore, unauthorized replacement or theft of the main control device 271 can be effectively prevented.

  The main control device 271 is arranged on the near side when viewed from the back of the pachinko machine 1, and the sound lamp control device 272 is arranged on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with a step in the front-rear direction, each control device 271, 272 is arranged with a part thereof overlapped in the front-rear direction. That is, as can be seen in FIG. 14 and the like, the main controller 271 is arranged in a state where a part thereof (about 1/3 in this configuration) is floated. Therefore, it is possible to extend the sound lamp control device 272 to a region overlapping the main control device 271. From another viewpoint, the main control device 271 can be extended to a region overlapping the sound lamp control device 272. Even in the limited size of the pachinko machine 1, it is possible to cope with an increase in the size of each control board (each control device) 271 and 272, and each control device 271 and 272 can be efficiently installed. Can be installed. Further, when the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252 so that the variable winning device 32 and its electric wiring can be installed without difficulty. Grid-like ribs 258 are provided on the back surface of the substrate mounting surface 252 to enhance the support strength of the main control board (main control device) 271.

  In the present embodiment, a RAM erasure switch 323 is provided in the substrate box 273 that accommodates the main substrate. This pachinko machine 1 has a backup function for various data. Even if a power failure occurs, the pachinko machine 1 maintains the state at the time of the power failure, and returns to the state at the time of the power failure when returning from the power failure (power recovery). It can be done. Therefore, for example, when the power supply is shut down in the normal procedure, as in the case of the business hall being closed, the state before the power shut-off is stored, but if the power is turned on while pressing the RAM erase switch 323, the data stored in the RAM is stored. Is to be initialized. This configuration will be described in detail later.

  A pair of upper and lower retaining pins 261 is provided on the left end surface of the mounting base 251. By attaching the retaining pins 261 to the bearing bracket 231, the first control board unit 201 can rotate with respect to the game board 30. Cantilevered so that it can move. A pair of upper and lower nai latches 262 are provided at the right end of the mounting base 251 as fasteners to be fitted into the fastening holes 232. A long hole 263 in which the locking claw piece 233 is locked is provided at the upper end portion of the mounting base 251. Therefore, the first control board unit 201 is fixed to the game board 30 by fitting the nai latch 262 into the tightened hole 232 and locking the locking claw piece 233 in the long hole 263. The bearing fitting 231 and the latch pin 261 correspond to the support shaft portion M1, the fastened hole 232 and the ny latch 262 correspond to the fastening portion M2, and the locking claw piece 233 and the long hole 263 correspond to the locking claw portion M3, respectively.

Based on the information in the backup area 513a, the state of the pachinko machine 1 can be restored to the state before power-off. Writing to the backup area 513a is executed when the power is shut off by the NMI interrupt processing, and restoration of each value written to the backup area 513a is executed in the main processing when the power is turned on. Note that the power failure signal SG1 is input to the NMI terminal of the CPU 511 of the payout control device 311 from the power failure monitoring circuit 542 via the power device 313 when the power is shut down due to the occurrence of a power failure or the like.

The input / output port 515 is connected to a power failure monitoring circuit 542, a main controller (main board) 271, a launch controller 312 and a payout motor 358a. As will be described in detail later, in this embodiment, an output signal from a RAM erase switch circuit 543, which will be described later, is not input to the input / output port 514 of the payout control device 311 but is input to the main control device 271. Only the output port 505 is input.

  The launch control device 312 permits or prohibits the launch of the game ball by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. Specifically, it is detected by a sensor signal that a firing permission signal is output from the payout control device 311, that the player is touching the game ball launch handle 7, and a launch for stopping the launch. On condition that the stop switch is not operated, the launch motor 229 is driven, and the game ball is launched with a strength corresponding to the operation amount of the game ball launch handle 7. In the present embodiment, the payout control device 311 and the launch control device 312 are configured independently of each other, but may be configured integrally as a launch / payout control device (substrate).

  Based on the symbol display command output from the main controller 271, the display control device 214 performs variable display (variable display) of the first symbol (special symbol) in the first symbol display device 41, and the second symbol display device 42. This controls the display of variation of the second symbol (ordinary symbol). The display control device 214 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 525, a character ROM 526, an image controller (VDP) 524, an input port 527, two output ports 528 and 529, a bus line. 530 and 531.

Further, an output port 529 is connected to the image controller (VDP) 524 via a bus line 531, and a first symbol display device 41 which is a liquid crystal display device is connected to an output of the output port 529.

  The CPU 521 of the display control device 214 controls the display of the first symbol display device 41 and the second symbol display device 42 based on the symbol display command transmitted from the main control device 271. The program ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 temporarily stores work data and flags used when the CPU 521 executes various programs. It is a memory for.

  The video RAM 525 is a memory for storing display data displayed on the first symbol display device 41, and the display content of the first symbol display device 41 is changed by rewriting the contents of the video RAM 525. The character ROM 526 is a memory for storing character data such as symbols displayed on the first symbol display device 41.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 1. 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 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.

  Furthermore, the power supply device 313 is equipped with a capacitor 313a. The capacitor 313a is used to supply holding power to the payout control device 311 in order to hold the storage contents of the RAM 513 of the payout control device 311 when the power supplied by the power supply means is cut off. It is. The pachinko machine 1 includes a capacitor 402 as a backup power source for holding the stored contents of the RAM 503 of the main controller 271, which will be described later.

  As described above, in the pachinko machine 1, when the game is interrupted due to the occurrence of a power failure or the like by backing up the storage contents of the RAM 503 of the main controller 271 and the RAM 513 of the payout controller 311 when the power is shut off Even so, when the power is turned on, the state of the pachinko machine 1 can be restored to the state before the power is shut off. Thus, for example, even if a power failure occurs in a gaming state advantageous to the player, such as during a jackpot game or a probability variation game, when the power is turned on, the player can continue the game from that gaming state. In addition, it is possible to prevent a situation in which a prize ball originally acquired by the player is lost due to a power failure, and does not cause any disadvantage to the player.

  By the way, when an unexpected error occurs in the data stored in the RAMs 503 and 504, a malfunction occurs in the operation of the pachinko machine 1, or the gaming state of the pachinko machine 1 is a jackpot state or a probability variation gaming state. For example, when the pachinko machine 1 is turned off for the closing time in a game state advantageous to the player, it is necessary to return the game state of the pachinko machine 1 to the initial state. Therefore, the pachinko machine 1 erases (clears) the backup data stored in the RAM 503 of the main controller 271 and the RAM 513 of the payout controller 311, initializes the storage contents of the RAMs 503 and 513, and The gaming state can be returned to the initial state.

  Specifically, in the present embodiment, the initialization circuit board 401 is housed and fixed together with the main board 271a of the main controller 271 in the board box 273 of the main controller 271. A RAM erasure switch 323 for erasing (clearing) the backup data and initializing the storage contents of the RAMs 503 and 513 is mounted. The RAM erase switch circuit 543 detects the operation state of the RAM erase switch 323, and outputs a RAM erase signal SG2 as a detection signal when the RAM erase switch 323 is pressed.

  In this embodiment, the RAM erase signal SG2 is output only to the main board 271a of the main controller 271. The CPU 501 of the main controller 271 receives the backup data stored in the RAM 513 in response to the input of the RAM erase signal SG2. A payout initialization command Cm, which is an instruction to erase and initialize data, is transmitted to the payout control device 311. More specifically, the payout initialization command Cm is stored in advance in the ROM 502 of the main controller 271 as one instruction set (command group) to be sent to the payout control device 311, and the RAM erase signal SG2 Is input to the CPU 501 via the input / output port 505, the CPU 501 transmits it to the payout control device 311. At this time, the payout initialization command Cm is transmitted from the CPU 501 as a digital signal sequence, and is input to the input / output port 515 of the payout control device 311 via the bus line 504, the input / output port 505, and a predetermined communication line. In addition, when the RAM erasing signal SG2 is input, the CPU 501 of the main control device 271 also performs an erasing operation of backup data stored in the RAM 503 of the main control device 271 along with the transmission of the payout initialization command Cm. As a result, the stored contents of the RAM 503 are initialized.

  On the other hand, the payout initialization command Cm input to the input / output port 515 of the payout control device 311 is input to the CPU 511 via the bus line 515 of the payout control device 311 and executed by the CPU 511. As a result, the backup data stored in the RAM 513 is deleted, and the storage contents of the RAM 513 are initialized.

  As described above, when the power of the bachinko machine 1 is turned on while the RAM erase switch 323 is pressed (including power-on due to power failure cancellation), the main controller 271 and the payout controller 311 each have the RAM 503, The backup data stored in 513 is erased (cleared), whereby the storage contents of the RAMs 503 and 513 are initialized. As a result, various backup data (more specifically, register values and counter values of various counters to be described later) stored in the RAM 503 of the main control device 271 and various types of data stored in the RAM 513 of the payout control device 311 are stored. Since the backup data (more specifically, the number of award balls that have not been paid out when the power is turned off) is deleted, the gaming state of the pachinko machine 1 is not the gaming state at the time of turning off the power but the initial state. In other words, when an unexpected error occurs in the data stored in the RAMs 503 and 504 and a malfunction occurs in the operation of the pachinko machine 1, or when the game state of the pachinko machine 1 is returned to the initial state. After the power of the pachinko machine 1 is cut off, the RAM 503 and 504 are initialized by turning on the power again with the RAM erase switch 323 pressed, so that the gaming state of the pachinko machine 1 can be returned to the initial state.

  Further, in the present embodiment, when the power supplied from the power supply device 313 to the initialization circuit board 401 is cut off, the main control is performed with the holding power for holding the storage contents of the RAM 503 of the main control device 271. A capacitor 402 serving as a holding power supply means for supplying power to the device 271 and a power failure monitoring circuit 542 for monitoring power interruption due to a power failure or the like are mounted, and a backup substrate for retaining the storage contents of the RAM 503 of the main control device 271 It is also used as.

  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 controller 271 and the CPU 511 of the payout controller 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 a 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 failure) has occurred when this negative pressure becomes 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 a power failure process (NMI interrupt process in FIG. 37). The initialization circuit board 401 is also equipped with a reset circuit (not shown) for normal on / off.

  Next, the mechanism for supplying the holding power by the capacitor 402 of the initialization circuit board 401 will be described. As shown in FIG. It is connected to the normal drive power supply terminal VDD of the CPU 501. The power supply device (power supply board) 313 is connected to the initialization circuit board 401 via the backup wiring 452 and then connected to the backup terminal VCAP of the CPU 501 of the main board 271a. In particular, the initialization circuit board 401 is provided with a diode 403 and a capacitor 402 for preventing reverse current flow, and the power supply device (power supply board) 313 and the CPU 501 are connected via the diode 403 and the capacitor 402. Yes.

  Therefore, when normal drive power is supplied from the power supply device 313 to the main board 271a via the normal drive wiring 451, power is also supplied from the power supply device 313 to the capacitor 402 via the backup wiring 452. Electric power is stored in the capacitor 402 as holding electric power. In addition, when the power is shut off, the power stored in the capacitor 402 is supplied to the CPU 501 (RAM 503) as retained power, thereby backing up data and the like.

  Note that the normal drive wiring 451 may directly connect the power supply device (power supply board) 313 and the main board 271a, or via the initialization circuit board 401 (without the capacitor 402). There may be. When the initialization circuit board 401 is used, both wirings 451 and 452 can be connected to each other, and there is an advantage that the wiring complexity can be suppressed.

  Here, supplementing the schematic configuration of the power supply device (power supply board) 313, in addition to the power supply unit 541 and the capacitor 313a, the power supply device (power supply board) 313 receives at least (1) noise from the power supply outlet (AC24V). A coil for removing, (2) an A / D converter for converting AC24V to DC32V, (3) an electrolytic capacitor (which is different from the capacitor 313a) for suppressing variations in supply voltage and achieving stabilization, (4 ) A D / D converter or the like (both not shown) for converting DC32V to the above-mentioned DC5V or DC12V is mounted. Of these, with respect to (1), some noise may also be generated from the coil. In particular, with respect to (2) to (4), heat and noise may be generated. That is, it can be said that the power supply device (power supply board) 313 includes various circuits that generate noise and / or generate heat, and serves as a noise source and / or a heat generation source.

  Next, the arrangement structure of the main board 271a and the initialization circuit board 401 in the board box 273 will be described with reference to FIGS. As described above, the substrate box 273 includes the box base 273A having a substantially rectangular parallelepiped shape and the box cover 273B that closes the opening of the box base 273A. A boss BA is erected on the box base 273A, and the main board 271a is attached to the boss BA with a screw (not shown) as a fixing member. On the other hand, a boss BB is erected on the box cover 273B of the board box 273, and the initialization circuit board 401 is attached to the boss BB with a screw (not shown) as a fixing member. That is, the main board 271a is fixed to the box base 273A side, and the initialization circuit board 401 is fixed to the box cover 273B side.

A connector having an insertion port into which the insertion portion of the connector 271C is inserted into the right edge portion of the circuit board 401, that is, the edge portion on the side where the main substrate 271a is disposed so as to face the connector 271C. 401C protrudes toward the connector 271C. Accordingly, when the box cover 273B is closed and the opening of the box base 273A is closed, the connector 401C on the initialization circuit board 401 side is inserted into the connector 271C on the main board 271a side. 271a and initialization circuit board 401 are electrically connected.

  More specifically, guide rails GR are formed on the upper and lower edge portions (upper side portion and lower piece portion) of the box cover 273B, and flange portions on both upper and lower edges of the box base 273A are formed in the guide rail GR. It is loosely fitted. That is, the box base 273A and the box cover 273B are brought into contact with each other, and are slid linearly (one-dimensionally) along the guide rail GR. The insertion of 401C is performed, the opening of the box base 273A is closed by the box cover 273B, and the box base 273A and the box cover 273B are joined to each other. As a result, both the main board 271a and the initialization circuit board 401 are accommodated in the board box 273, and the box base 273A and the box cover 273B are connected to the main board 271a and the initial stage by being connected by the sealing unit 319. The circuit board 401 and the substrate box 273 are hermetically sealed.

  In the present embodiment, the main board 271a and the initialization circuit board 401 are each provided with external connection means for establishing an electrical connection with an external device. More specifically, the main board 271a is provided with an external connection terminal (not shown), and the external connection terminal is exposed from the main board window W1 provided on the box base 273A. That is, when the main board 271a is fixed to the box base 273A with screws, the external connection terminals provided on the main board 271a are exposed from the main board window W1, and the external connection terminals are exposed to the external connection terminals from the outside of the box base 273A. The connector cable connector is configured to be connectable.

  On the other hand, the initialization circuit board 401 is provided with an external fixed terminal (not shown) as external connection means. In the present embodiment, the external fixed terminal of the initialization circuit board 401 is not directly exposed from the box base 273A, but is configured to expose the connector of the cable connector connected to the external fixed terminal. . More specifically, the box base 273A is formed with an initialization circuit board window W2 separately from the main board window W1. In the present embodiment, the external fixed terminal of the initialization circuit board 401 is directly exposed from the initialization circuit board window W2 for the convenience of sliding the box base 273A and the box cover 273B to each other. It is difficult. Therefore, the connector at one end of the cable connector is connected to the external fixing terminal of the initialization circuit board 401, and the connector at the other end of the cable connector is fixed to the initialization circuit board window W2 and exposed.

  Next, the operation of the pachinko machine 1 configured as described above will be described.

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information during the game to perform jackpot lottery, setting of symbol display of the first symbol display device 41, and the like. Specifically, As shown in FIG. 29, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 41, and the first symbol display device 41 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there.

  Among these counters, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that add 1 to the previous value every time they are updated, and return to 0 after reaching the maximum value. The out symbol counters CL, CM, and CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the operation port 33 is provided. The values of the jackpot random number counter C1, the jackpot symbol 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 by a loop counter that increments one by one within a range of, for example, 0 to 676, and returns to 0 after reaching the maximum value (that is, 676). 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 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 number of random number values that are jackpots is set in the normal probability state and the high probability state, and the number of random number values that are jackpots in the normal probability state is 2, and its value is “337, 673 ”and the number of random number values that are jackpots in the high probability state is 10, and the values are“ 67, 131, 199, 269, 337, 401, 463, 523, 601 and 661 ”.

  The jackpot symbol counter C2 determines the symbol when the first symbol display device 41 stops changing in the case of a jackpot. In the present embodiment, the first symbol display device 41 has five effective lines. Since 10 kinds of specific symbols (main symbols) are set, 50 (0 to 49) counter values are prepared. In other words, the jackpot symbol 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 (that is, 49), it returns to 0. The jackpot symbol counter C2 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.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not occur reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 41, the number of suspended 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.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented one by one within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”. The first variation type counter CS1 determines 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 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The 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 the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the variation of the first symbol is started by the first symbol display device 41.

  The left, middle and right off symbol counters CL, CM, and CR are used to 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 updated at random by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the value of the lower 3 bits of the R register is added to the previous value, and when the addition result exceeds the maximum value, 20 is subtracted to determine the current value. The Each out symbol counter CL, CM, CR is updated within the normal processing and the remaining time of the normal processing so that the update times do not overlap, and the combination of these out symbol counters CL, CM, CR is out of front and back of the RAM 503. Stored in one of the reach symbol buffer, the reach symbol buffer other than front-rear detachment, and the complete detachment 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 complete 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 symbol random number counter C4 is used for the lottery of the second symbol display device 42. The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 in the main controller 271 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is 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. As shown in this figure, in the timer interrupt process, the CPU 501 of the main control device 271 executes various winning switch reading processes (step S601). 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, the random number initial value counter CINI is updated (step S602). 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. Subsequently, the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are updated (step S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are incremented by “1”, respectively, and the counter values are maximum values (in this embodiment, 676, 49, and 238, respectively). When it reaches, it is cleared to “0”. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Next, a start winning process associated with winning in the operating port 33 is executed (step S604). This start winning process will be described with reference to the flowchart of FIG. 36. First, it is determined whether or not the game ball has won the start opening 33 (start winning prize) based on the detection information of the operation opening switch 224 (step S701). When it is determined that the game ball has won the operating port 33, it is determined whether or not the number N of the operation reservation balls of the first symbol display device 41 is less than the upper limit value (4 in the present embodiment) (step S702). ). The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by “1”. Subsequently, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area of the free storage area of the reserved ball storage area of the RAM 503 (step S704). Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

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

  FIG. 37 is a flowchart showing the NMI interrupt processing. This processing is executed by the CPU 501 of the main control device 271 when the power of the pachinko machine 1 is shut down 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 1 is cut off due to the occurrence of a power failure or the like, a power failure signal SG1 is output from the power failure monitoring circuit 542 mounted on the initialization circuit board 401 to the NMI terminal of the CPU 501 in the main controller 271. The CPU 501 interrupts the control being executed and starts NMI interrupt processing. This NMI interrupt processing program is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing, the CPU 501 of the main control device 271 saves the used registers in the backup area 503a of the RAM 503 (step S801), and stores the stack pointer value in the backup area 503a (step S802). Further, the occurrence information of the power shutdown is set in the backup area 503a (step S803), and a power shutdown notification command indicating that the power is shut off is output to another control device (step S804). Then, a RAM determination value is calculated and stored in the backup area 503a (step S805), and RAM access is prohibited (step S806). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. 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 1 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 mounted on the initialization circuit board 401 to the NMI terminal of the CPU 511 in the payout control device 311. The CPU 511 interrupts the control being executed and starts the NMI interrupt process of FIG. The contents are the same as described above except that the output of the power-off notification command in step S804 is not performed.

  FIG. 30 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 this main process, an initial setting process associated with power-on is first executed (step S101). 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. Then, the RAM access is permitted (step S102).

  Thereafter, the CPU 501 executes data backup processing for the RAM 503 in the CPU 501. That is, it is determined whether or not the RAM erase switch 323 provided in the substrate box 273 of the main controller (main substrate) 271 is pressed (step S103). If the RAM erasing switch 323 is not pressed, that is, if the RAM erasing signal SG2 is not input (step S103: NO), the payout for instructing the payout control device 311 to execute the prize ball payout control. The permission command is output (step S104), and if the RAM erase switch 323 is pressed, that is, if the RAM erase signal SG2 is input (step S103: YES), the RAM 513 is instructed to be initialized. A payout initialization command Cm is transmitted to the payout control device 311 (step S114). After the RAM erasure switch 323 is not pressed and the payout permission command is output to the payout control device 311, the CPU 501 determines whether or not the information on the occurrence of power interruption is set in the backup area 503 a of the RAM 503. (Step S105). If the power-off occurrence information is set (step S105: YES), a RAM determination value is calculated (step S106), and the RAM determination value matches the RAM determination value stored at the time of power-off. NO, that is, the validity of the backup is determined (step S107). 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 1, when the RAM data is initialized when the power is turned on, for example, when the hall starts business, the power is turned on while the RAM erase switch 323 is pressed. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to RAM initialization processing (steps S114 to S117). Similarly, when the occurrence information of power shutdown is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 503 (steps S114 to S117). . In the initialization process of the RAM 503, first, the above-described payout initialization command Cm is transmitted to the payout control apparatus 311 so that the RAM511 of the payout control apparatus 311 is also initialized (step S114). ). Thereafter, the use area of the RAM 503 of the main controller 217 is cleared to “0” (step S115), and initialization processing of the RAM 503 is executed (step S116). Then, after setting the interrupt permission (step S117), the routine proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed (step S103: NO), the occurrence information of the power shutdown is set (step S105: YES), and the RAM judgment value (checksum value etc.) is normal. On condition that it is present (step S107: YES), the process at the time of power recovery (process at the time of power-off restoration) is executed. That is, as a process at the time of power-off recovery, the stack pointer before power-off is restored (step S108), and information on occurrence of power-off is cleared (step S109). Then, a command for returning the sub-side control device to the gaming state at the time of power-off is output (step S110), and the used register is returned from the backup area 503a of the RAM 503 (step S111). Then, in order to return the interruption permission / non-permission to the state before the power interruption, if the interruption permission is given before the power interruption (step S112: YES), after setting the interruption permission (step S113), the power supply If the interrupt permission is not given before the interruption (step S112: NO), the process returns to the address before the power interruption.

  Next, the flow of normal processing executed by the CPU 501 in the main controller 271 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 processing, first, output data such as a command updated in the previous processing is output to each control device on the sub side (step S201). 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 output to the payout control device 311. In addition, when the first symbol display device 41 displays the variation of the first symbol, a symbol display command such as a variation pattern command, a stop symbol command, and a confirmation command is output to the display control device 214. When the first symbol is started to change, one change is made for each normal process in the following order: change pattern command → stop symbol command for left symbol sequence → stop symbol command for middle symbol sequence → stop symbol command for right symbol sequence A command is output (that is, one every 4 msec), and a confirmation command is output at the timing when the fluctuation time elapses.

  Next, the fluctuation type counters CS1 and CS2 are updated (step S202). Specifically, the variation type counters CS1 and CS2 are incremented by “1”, and are cleared to “0” when the counter values reach the maximum values (198 and 240 in the present embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503. Subsequently, the outlier counters CL, CM, CR of the left symbol row, middle symbol row, and right symbol row are updated (step S203).

  The update process of each outlier symbol counter CL, CM, CR will be described. As shown in FIG. 32, the CPU 501 in the main controller 271 determines whether it is time to update the outlier symbol counter CL in the left symbol row (step If it is not the update time (step S301: NO), it is determined whether or not it is the update time of the out-of-medium symbol row symbol counter CM (step S302). On the other hand, if it is the time to update the left symbol sequence (step S301: YES), the processing procedure proceeds to step S303, and the left symbol sequence outlier symbol counter CL is updated. If the middle symbol row update time (step S302: YES), the process proceeds to step S304, and the middle symbol row outlier symbol counter CM is updated. Furthermore, if it is not the update timing of the left symbol and the middle symbol but the update timing of the right symbol sequence (NO in both steps S301 and S302), the processing procedure proceeds to step S305 to update the symbol symbol CR out of the right symbol sequence. . In updating the outlier symbol counters CL, CM, and 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. Then, the calculation result is removed, and the current values of the symbol counters CL, CM, and CR are used. According to the above-described 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.

  After that, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination (step S306). If it is a jackpot symbol combination (step S306: YES), The process ends. If it is not a jackpot symbol combination (step S306: NO), it is determined whether or not it is a reach symbol combination (step S307), and if it is a reach symbol combination (step S307: YES), it is a back and forth reach reach It is determined whether or not (step S308). If the off symbol counters CL, CM, and CR are combinations of front and rear out of reach (step S308: YES), the combination of out symbol counters CL, CM, and CR at that time is stored in the front and rear out of reach symbol buffer of the RAM 503 (step S309). ). When the out symbol counters CL, CM, CR are a combination of reach other than front / back off (step S308: NO), 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. (Step S310). In addition, when the combination of the off symbol counters CL, CM, and CR is not a combination of the jackpot symbol and neither of the reach symbols (when both steps S306 and S307 are NO), this is the case of the off symbol counters CL, CM, and CR. The combination corresponds to a combination of out-of-designs. In such a case, the combination of out-of-design counters CL, CM, CR at that time is stored in the complete out-of-design symbol buffer of the RAM 503 (step S311).

  After update processing of the off symbol counters CL, CM, and CR, the processing procedure proceeds to step S204 in FIG. 31, and a prize ball counting signal and a payout abnormality signal input from the payout control device 311 are read. Thereafter, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed (step S205). By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

  Thereafter, the processing procedure proceeds to step S206, and a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 32 in the case of the big win state is executed. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Next, display control of the second symbol (for example, “◯” or “x” ordinary symbol) by the second symbol display device 42 is executed (step S207). Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second symbol random number counter C4 is acquired and the second symbol is displayed on the display unit 45 of the second symbol display device 42. The variable display is implemented. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the operating port 33 is released for a predetermined time. Although the description is omitted, the second symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 35, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3.

  Thereafter, it is determined whether or not the execution timing of the next normal process 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 (step S208). If the predetermined time has not yet elapsed (step S208: NO), the random number initial value counter CINI, the variation type counters CS1 and CS2, and the left, middle, and right within the remaining time until the next normal processing execution timing. The update symbol counters CL, CM, and CR are repeatedly updated (steps S209, S210, and S211). 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, update of the variation type counters CS1 and CS2 is executed. Specifically, the variation type counters CS1 and CS2 are incremented by “1”, and are cleared to “0” when the counter values reach the maximum values (198 and 240 in the present embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503. In step S211, the left, middle, and right off symbol counters CL, CM, and CR are updated. This update process is also performed in the same manner as the update process for the left, middle, and right outlier counters CL, CM, and CR shown in FIG.

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, by repeatedly updating the random number initial value counter CINI using the remaining time, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random. Similarly, The fluctuation type counters CS1 and CS2 and the left, middle and right outlier counters CL, CM and CR can also be updated at random. The left, middle, and right outlier counters CL, CM, and CR may be updated either in the normal process (step S203) or in the remaining time (step S211).

  Next, the first symbol variation process of step S205 will be described with reference to the flowcharts of FIGS.

  In the first symbol variation process, the CPU 501 in the main controller 271 determines whether or not the jackpot is currently being hit (step S401). The jackpot includes the jackpot game displayed on the first symbol display device 41 in the jackpot and the middle of a predetermined time after the jackpot game ends. Subsequently, it is determined whether or not the first symbol display device 41 is displaying the variation of the first symbol (step S402). Then, if the jackpot is not being won and the variation of the first symbol is not being displayed (when both steps S401 and S402 are NO), the processing procedure proceeds to step S403, and the number N of the operation suspended balls of the first symbol display device 41 is “ It is determined whether or not it is larger than “0”. On the other hand, if it is a big hit (step S401: YES), or if the number N of active suspension balls is “0” (step S403: NO), there is no need to display the symbol variation, so this process is terminated. To do.

  On the other hand, if neither the big hit or the change in the first symbol is being displayed and the number N of activated suspension balls is greater than 0 (step S402 is NO and step S403 is YES), the number of suspended operation balls N is set to “ 1 "is decremented (step S404), and the process of shifting the data stored in the reserved ball storage area is executed (step S405). This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, the first symbol variation start process is executed (step S406). Here, the details of the variation start process will be described with reference to the flowchart of FIG. 34. The CPU 501 in the main control device 271 determines whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. It is determined whether or not (step S501). Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337, 673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at a normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523, at a high probability. “601, 661” is the winning value.

  When it is determined that it is a big hit (step S501: YES), a table corresponding to the value of the big hit symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the big hit symbol (big hit symbol counter C2) And the symbol is set as a stop symbol command (step S502). At this time, the numbers 0 to 49 of the jackpot symbol 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. If these jackpot symbols are aligned with a predetermined specific symbol (the main symbol of the first symbol), then the process shifts to a probable change state, but if they are aligned with a symbol that is not a specific symbol (non-specific symbol), the probability changes Does not transition to the state.

  Next, the variation pattern of the first symbol until it stops at the jackpot symbol is determined (step S503), and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the reach type such as normal reach, super reach, premium reach, etc., and other roughly based on the value of the first variation type counter CS1 And the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) More detailed pattern variation modes are determined. 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, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set or to set the pattern with both values of both variation type counters CS1 and CS2 is appropriately determined according to the value of the first variation type counter CS1 and the game conditions each time. 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 it is not a big hit (step S501: NO), it is determined 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. (Step S504) In the case of reach occurrence (Step S504: YES), it is similarly determined whether or not it is out-of-front reach based on the value of the reach random number counter C3 (Step S505). In the present embodiment, the value of the reach random number counter C3 is any one of “0 to 238”, among which “0, 1” corresponds to the front / rear outreach and “2-21” corresponds to the reach other than the front / rear out of reach. “22 to 238” corresponds to no reach (complete detachment).

  When the front / rear out of reach has occurred (step S505: YES), the left, middle and right out of symbol counters CL, CM, CR stored in the front / rear out of reach design buffer of the RAM 503 are set as stop symbol commands. (Step S506). Then, a fluctuation pattern for front / rear out of reach display is determined (step S507), and the fluctuation pattern is set as a fluctuation pattern command. At this time, as in step S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. The reach type (such as the middle symbol in the present embodiment) is stopped after the occurrence of the reach based on the value of the second variation type counter CS2 In other words, a more detailed symbol variation mode such as the number of variation symbols) is determined.

  When a reach other than front / rear out is generated (step S505: NO), 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 used as stop symbol commands. Setting is performed (step S508). Then, a variation pattern for reach display other than front / rear deviation is determined (step S509), and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like.

  If neither big win nor reach (if both steps S501 and S504 are NO), the left, middle, and right out symbol counters CL, CM, and CR stored in the completely out symbol buffer of the RAM 503 Is set as a stop symbol command (step S510). Then, a variation pattern for complete out-of-range display is determined (step S511), and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like. As described above, when the setting of the fluctuation pattern command and the stop symbol command is completed in any of the big hit, the reach occurrence, and the reach non-occurrence, this processing is ended.

  Returning to the description of FIG. 33, if step S402 is YES, that is, if the variation of the first symbol is being displayed, it is determined whether or not the variation time has elapsed (step S407). At this time, the variation time of the first symbol is determined according to the variation pattern of the first symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. If an affirmative determination is made in this way, a confirmation command set for confirming the stop symbol is set (step S408), and then this process ends. Details of display control performed by the display control device 214 based on the first symbol variation process by the main control device 271 will be described later.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 38 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

  First, the CPU 511 executes an initial setting process associated with power-on (step S901). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Then, after permitting RAM access (step S902), an external interrupt vector is set (step S903).

  Thereafter, a data backup process is executed for the RAM 513 in the CPU 511. That is, in step S904, whether or not the RAM erase switch 323 provided in the board box 273 is pressed is determined based on whether or not the payout initialization command Cm output from the control device 271 is received. If the payout initialization command Cm has not been received (step S904: NO), it is determined whether or not a payout permission command output from the main controller 271 has been received (step S905). As a result of these determinations, if neither the payout initialization command Cm nor the payout permission command has been received (NO in both steps S904 and S905), the processing procedure is performed to wait until either command is received. It returns to step S904. If the payout permission command is received (step S905: YES), the process proceeds to step S906, and it is determined whether or not the information on occurrence of power interruption is set in the backup area 513a of the RAM 513. In step S907, a RAM determination value is calculated. In subsequent step S908, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. 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.

  On the other hand, when the payout initialization command Cm is received (step S904: YES), the process proceeds to a RAM initialization process (steps S915 to S918). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (steps S915 to S918). . That is, in step S915, the entire area of the RAM 513 is cleared to “0”, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the payout initialization command Cm has not been received (step S904: NO), the payout permission command has been received, the power-off occurrence information has been set, and the RAM determination value (check The processing at the time of power recovery (processing at the time of power-off restoration) is executed on condition that the sum value is normal. That is, in step S909, the stack pointer prior to power shutdown is restored, and in step S910, information on occurrence of power shutdown is cleared. In step S911, the CPU peripheral device is initialized, and in step S912, the used register is restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the 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 payout control processing executed by the CPU 511 of the payout control device 311 will be described with reference to the flowchart of FIG.

  In FIG. 39, the CPU 511 of the payout control device 311 acquires a command from the main control device 271 and stores the total number of winning balls (step S1001). Next, launch permission is set for the launch controller 312 (step S1002). Then, 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 (step S1003).

  Thereafter, the setting of the lower pan full tank state or the lower pan full tank release state is executed according to the change in the state of the lower pan 13 (step S1004). That is, when the lower pan 13 is determined to be full according to 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. Next, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change in the state of the tank ball (step S1005). In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration.

  Thereafter, the presence / absence of a notification state is determined, and if there is a notification state, notification is made by a 7-segment LED provided in the payout control device 311 (step S1006). Next, in steps S1007 to S1009, prize ball payout processing is executed. That is, it is determined whether or not the prize balls cannot be paid out (step S1007). If the prize balls cannot be paid out, it is determined whether or not the total number of prize balls stored in step S1001 is “0” (step S1007). Step S1008). If the prize ball is not paid out and the total number of prize balls is not “0” (both NO in steps S1007 and S1008), a prize ball control process described later shown in FIG. 40 is started (step S1009). On the other hand, if the prize ball cannot be paid out or if the total number of prize balls is “0” (YES in either step S1007 or S1008), the process proceeds to the lending and payout process shown in steps S1010 to S1012.

  In the rental payout process, it is first determined whether or not the payout state of the rental ball is disabled (step S1010). If it is not disabled (step S1010: NO), a rental payout request from the card unit is determined. Whether or not is input is determined (step S1011). If a ball rental payout request is input (S1011: YES), a ball rental control process described later shown in FIG. 41 is started (step S1012). On the other hand, if a rental ball payout disabled state or a rental ball payout request has not been input (YES in step S1010 or NO in step S1011), subsequent ball removal processing is executed.

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

  Here, in the winning ball control process shown in FIG. 40, the payout motor 358a is driven to pay out the winning ball (step S1101). Subsequently, whether the rotation of the dispensing motor 358a is normal is determined based on the detection result of the dispensing rotation sensor (step S1102). If the rotation of the payout motor 358a is not normal (step S1102: NO), the payout motor 358a is driven to execute retry processing and stop processing of the payout motor 358a (step S1103), and then the payout shown in FIG. Return to control processing.

  If the rotation of the payout motor 358a is normal (step S1102: YES), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (step S1104). If the game ball count is not normal (step S1104: NO), the payout motor 358a is driven to execute the retry process and the payout motor 358a is stopped (step S1105), and then the payout control of FIG. Return to processing.

  On the other hand, if the game ball count is normal (step S1104: YES), it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout is completed (step S1106). If the payout has been completed (step S1106: YES), the payout motor 358a is stopped in step S1107, and then the payout control process in FIG. 39 is returned to.

  In the ball rental control process shown in FIG. 41, the payout motor 358a is driven to pay out a ball (step S1201). Subsequently, whether the rotation of the dispensing motor 358a is normal is determined based on the detection result of the dispensing rotation sensor (step S1202). If the rotation of the payout motor 358a is not normal (step S1202: NO), the payout motor 358a is driven to execute retry processing and stop processing of the payout motor 358a (step S1203), and then the payout shown in FIG. Return to control processing.

  If the rotation of the payout motor 358a is normal (step S1202: YES), it is determined from the detection result of the payout count switch whether the game ball is normally counted (step S1204). If the game ball count is not normal (step S1204: NO), the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped (step S1205), and then the payout control of FIG. Return to processing.

  Further, if the game ball count is normal (step S1204: YES), 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. (Step S1206). If the payout has been completed (step S1206: YES), the payout motor 358a is stopped (step S1207), and then the process returns to the payout control process of FIG.

  Next, a specific procedure of display control by the display control device 214, particularly display control related to the first symbol variation display will be described. FIG. 42 is a flowchart showing display control processing executed by the CPU 521 in the display control device 214. The CPU 521 executes display control of the first symbol display device 41 while processing various commands from the main control device 271 according to the procedure shown in FIG.

  That is, the CPU 521 determines whether or not a symbol display command has been input from the main control device 271 (step S1301). If the determination result is NO, the system waits for some command to be input. When a symbol display command is input, the contents of the symbol display command are stored in the work RAM 523 (step S1302). Subsequently, various arithmetic processes such as generating an internal command for the VDP 524 are started based on the information stored in the work RAM 523 (step S1303). As a result, the VDP 524 performs a drawing process in accordance with a command (internal command) from the CPU 521 and starts the first symbol variation display on the first symbol display device 41. At this time, the CPU 521 outputs a control command for driving voices and lamps to the voice lamp control device 272 in synchronization with the display effect at each time. Thereby, the sound lamp control device 272 drives sounds and lamps in accordance with the control command from the CPU 521. Note that once the symbol display command is input, the symbol variation display is continued under the cooperation of the CPU 521 and the VDP 524 until the confirmation command is input thereafter. Meanwhile, the CPU 521 performs the control of the VDP 524 and the command reception process shown in FIG. 42 in parallel. The control in the sound lamp control device 272 is the same.

  Thereafter, it is determined whether or not a confirmation command has been input from the main controller 271 (step S1304). Then, the processing procedure is advanced to step S1305 on the condition that the confirmation command has been received, and the confirmation display with the stop symbol is instructed to the VDP 524. As a result, the VDP 524 confirms and displays the changed symbol as a stop symbol. In this way, one round of display processing is performed from the start of change of the symbol to the stop of change (definite display). The display control device 214 is controlled by the main control device 271 at the time of starting and stopping the change of the symbol, but the continuous change of the symbol during that time is a self-supporting image by the CPU 521 and the VDP 524 in the display control device 214. Secured by control.

  Although not specifically described in the flowchart, when initialization processing (steps S115, S116, steps S915, 916, etc.) of the RAMs 503 and 513 is performed, for example, a lamp, an alarm buzzer, etc. are not shown. That is notified by the teaching means. Thereby, the game hall official can reliably grasp that the initialization processing of the RAMs 503 and 513 has been performed.

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

  In the pachinko machine 1 according to the present embodiment, the initialization circuit board 401 on which the RAM erase switch circuit 543 is mounted is placed together with the main board 271a of the main controller 271 on the board box 273 that cannot be opened by the sealing unit 274. Contained. Therefore, for the purpose of illegally initializing the stored contents of the RAM 503 of the main controller 271, an illegal board (so-called hanging board) that outputs a signal instead of the RAM erase switch circuit 543 is replaced with the main board 271 a and the RAM. It becomes difficult to interpose between the erase switch circuit 543 and the erase switch circuit 543. Thereby, compared with the configuration in which the RAM erasing switch circuit 543 is provided outside the substrate box 273, it is possible to suppress fraudulent acts caused by so-called hanging.

  Further, in the pachinko machine 1, the RAM erase signal SG2 output from the RAM erase switch circuit 543 is output only to the main board 271a of the main controller 271 and is provided to the payout controller 311 provided outside the board box 273. The initialization command Cm is transmitted from the main board 271a of the main controller 271 instead of the RAM erase signal SG2. In this way, the RAM erase signal SG2 output from the inside of the board box 273 is output to the outside of the board box 273 as the initialization command Cm, so that a signal is output instead of the RAM erase switch 543. Even if the unauthorized board is inserted between the main controller 271 and the payout controller 311, the main controller 271 does not initialize the storage contents of the RAM 503 due to the influence of the signal from the unauthorized board. . Thereby, what is called hanging using the said unauthorized substrate is made impossible, and the above unauthorized acts can be suppressed more reliably.

  Here, an outline of the problem when the so-called hanging board as described above is improperly attached. If the storage contents of the RAM 503 of the main board 271a are illegally initialized by the hanging board, the random value including the jackpot random number counter C1 stored in the RAM 503 is initialized along with the initialization. Therefore, it is easy to generate the incoming signal aiming at the counter value that is a big hit. Specifically, in the pachinko machine 1, the initial value (count start point) of the big hit random number counter C1 that is a loop counter is periodically changed using the counter value of the random number initial value counter CINI that is randomly updated. However, although randomness is given to the appearance cycle of the counter value that is a big hit, when the RAM 503 is initialized, the counter value of the big hit random number counter C1 is initialized and the count start point is set to a predetermined value (for example, , “0”). That is, if the RAM 503 of the main control device 271 is illegally initialized, the randomness of the jackpot random number counter C1 is lost, thereby generating a pitch signal targeting the appearance timing of the counter value that is a jackpot, It becomes easy to generate the jackpot illegally. On the other hand, in the pachinko machine 1, as described above, since fraudulent acts are suppressed by so-called hanging, it is possible to prevent malicious acts such as illegally generating jackpots. is there.

  Further, according to the pachinko machine 1, the backup capacitor 402 is accommodated in the board box 273 together with the main board 271a. In other words, unless the sealing unit 274 is broken and the board box 273 is not opened, an illegal circuit for shutting off the holding power supply from the capacitor 402 to the main board 271a and illegally initializing the storage contents of the RAM 503, Since it is not possible to interpose between the capacitor 402 and the main board 271a, it is possible to suppress an illegal act by so-called hanging using this illegal circuit. Furthermore, when a malicious actor illegally opens the board box 273, the trace remains. Therefore, it is possible to easily find fraud by confirming it. Therefore, it is possible not only to directly prevent fraud but also to prevent fraud from the aspect of being able to detect fraud early.

  According to the pachinko machine 1, the CPU 501 of the main control device 271 outputs an initialization command Cm to the payout control device 311 and then initializes the storage contents of the RAM 503. A situation in which the initialization command Cm is not output due to deletion of information indicating that the initialization command Cm should be output is prevented, and the initialization command Cm is reliably output to the payout control device 311. be able to.

  According to the pachinko machine 1, the CPU 501 of the main control device 271 determines whether or not the RAM erase switch 323 is pressed every time power supply from the power supply device 313 is started. It is possible to prevent the control operation from being executed by the CPU 501 when the power is turned on even though the data includes data that should be deleted.

  Further, according to the pachinko machine 1, since the payout control device 311 waits until the initialization command or the permission command is input when the power is turned on, the backup data in the RAM 513 of the payout control device 311 includes an error. Although the data is to be deleted, it is possible to prevent the payout control device 311 from executing payout control based on the backup data when the power is turned on. Thereby, for example, when an error or the like occurs in the number of unpaid payout game balls being backed up, the RAM 513 can be initialized before the payout control device 311 executes payout control. It is possible to prevent payout based on the number of game balls including an error at the time of insertion.

  Further, according to the pachinko machine 1, when the CPU 501 of the main control device 271 outputs the initialization command Cm to the payout control device 311, the payout control device 311 stores the contents stored in the RAM 513 without outputting the permission command. Therefore, when the initialization command Cm is output, the main controller 271 does not need to separately output a permission command, and the processing of the main controller 271 is simplified. Can be

  In addition, according to the pachinko machine 1, the RAM erase switch circuit 543 is provided on the initialization circuit board 401 separate from the main board 271a. Therefore, it is necessary to change the design of the arrangement of electronic circuits on the main board 271a. Therefore, the design can be facilitated.

  In the pachinko machine 1, the main board 271a is fixed to the box base 273A, the initialization circuit board 401 is fixed to the box cover 273B, and the box base 273A and the box cover 273B are brought into contact with each other. Thus, when the opening of the box base 273A is closed by the box cover 273B, the connectors 271C and 401C are inserted and connected to each other, so that the main board 271a and the initialization circuit board 401 are electrically connected. Connected. Therefore, no separate connection work is required for electrical connection between the main board 271a and the pack-up board 401, and workability at the time of assembling the board box 273 can be improved. In particular, when the box base 273A and the box cover 273B are slid relative to each other, the connectors 271C and 401C are inserted and connected to each other only by sliding on a substantially straight line due to the presence of the guide rail GR described above. Therefore, the alignment can be performed easily and accurately, and the workability can be further improved.

  Further, when the board box 273 is opened, the electrical connection between the main board 271a and the initialization circuit board 401 is inevitably cut off. Therefore, by configuring so as to leave predetermined evidence when predetermined holding power is not supplied, evidence of fraud can remain, and fraud can be suppressed.

  In this embodiment, the main board 271a is fixed to the box base 273A and the initialization circuit board 401 is fixed to the box cover 273B. On the contrary, the main board 271a is fixed to the box cover 273B. The main board 271a is fixed, the initialization circuit board 401 is fixed inside the box base 273A, and the RAM erase switch 323 is provided outside the box base 273A, that is, of the box base 273A and the box cover 273B, The initialization circuit board 401 and the RAM erase switch circuit 323 may be provided on the front and back of the pachinko machine 1 as viewed from the back side.

  With this configuration, the RAM erase switch 323 and the initialization circuit board 401 are disposed on the front and back of the box base 273A. The RAM erase switch circuit 543 on the initialization circuit board 401 and the RAM erase switch 323 are connected to each other. For example, the wiring can be directly connected by wiring without detouring other substrates such as the main substrate 271a. Further, since the RAM erase switch 323 is provided on the exposed side, the operation of the RAM erase switch 323 can be facilitated and the operability can be improved.

  In the pachinko machine 1, both the external connection terminals provided on the main board 271a and the external fixed terminals provided on the initialization circuit board 401 can be wired from the box base 273A side. It is easy to perform wiring connection work with external devices. Further, even when the box base 273A and the box cover 273B are slid relative to each other, the cable connector is connected to the external fixed terminal provided on the initialization circuit board 401 and pulled out to the box base 273A side. In addition, it is possible to perform a slide movement or the like without causing any trouble while allowing the signal of the external device to be input to the external fixed terminal of the initialization circuit board 401.

  Further, in the pachinko machine 1, the main board 271a and the initialization circuit board 401 are flush with each other (on the same plane), and the connectors 271C and 401C are directly fixed to the boards 271 and 401, respectively. Therefore, it is possible to save labor for interposing a separate spacer in order to align the connectors 271C and 401C, and to ensure the stability of the attachment state of the connectors 271C and 401C, and thus to stabilize the connection status for a long time. Can be achieved.

  Further, in the pachinko machine 1, since the main board 271a and the initialization circuit board 401 are flush with each other (on the same plane), the electronic components (for example, the CPU 501) on the main board 271a are visually recognized from the outside. However, the initialization circuit board 401 is not hindered. In this sense, it is possible to relatively easily determine whether or not fraud related to the CPU 501 or the like has been performed, and it is possible to further suppress fraud. Further, the overall height (thickness) of the substrate box 273 can be reduced, and the thickness can be reduced.

  In the pachinko machine 1, the box base 273A and the box cover 273B are brought into contact with each other, and are slid to each other, and the above-described guide rail GR is extended to the upper side and the lower side. For example, a gap is not easily formed between the box base 273A and the box cover 273B. For this reason, it is possible to make it difficult to perform an illegal act on the main board 271a and the like.

  According to the pachinko machine 1, since the capacitor 402 is provided on the initialization circuit board 401 different from the main board 271a, noise, heat, and the like generated from the capacitor 402 cause the main board 271a (especially the CPU 501). It is prevented from being transmitted to. As a result, it is possible to suppress adverse effects on the main board 271a due to noise, heat, or the like.

  Furthermore, in addition to the capacitor 402, the power supply device (power supply board) 313 generates noise and heat, and there is a concern about these adverse effects. In this regard, in the present embodiment, the power supply device (power supply board) 313 is present at a position different from the board box 273 in which the main board 271a is accommodated, and therefore the above-described noise or the like adversely affects the CPU 501 or the like. Can be avoided.

  Further, according to the pachinko machine 1, since the RAM 513 of the payout control device 311 is configured to be initialized, even if an error occurs in the number of prize balls stored in the RAM 513, this Can be prevented, malfunctions such as paying out more than necessary prize balls can be prevented, and disadvantages can be prevented from occurring at the game machine store.

  Further, according to the pachinko machine 1, since the main control device 271 transmits the initialization command using the signal line used when transmitting the command relating to the prize ball or the permission command to the payout control device 311, Therefore, it is not necessary to newly provide a dedicated signal line for transmitting the command, and the wiring can be prevented from becoming complicated. In addition, since the complexity of the wiring can be avoided, it is possible to easily find an unauthorized circuit provided on the wiring, and it is also possible to prevent the cost of the pachinko machine 1 from being increased.

  Here, if the main control device 271 and the payout control device 311 are connected by a signal line capable of transmitting a signal only in one direction from the main control device 271 to the payout control device 311, the signal Even if the hanging board is inserted in the line, it is possible to prevent the signal output from the hanging board from being input to the main controller 271. However, in such a configuration, it is necessary to separately provide a signal line for transmitting a signal from the payout control device 311 to the main control device 271, and further, a signal output is provided to the main control device 271 and the payout control device 311. It is necessary to provide a dedicated terminal and a terminal dedicated to signal input, resulting in an increase in cost.

  In contrast to this configuration, according to the pachinko machine 1, the main control device 271 transmits the initialization command via a signal line for transmitting and receiving signals to and from the payout control device 311. Therefore, a separate signal line is not required, and the main control device 271 and the payout control device 311 do not need a signal output dedicated terminal and a signal input dedicated terminal. As a result, an increase in the cost of the pachinko machine 1 can be prevented, and further, since a signal line or the like is not required separately, an extra space for providing this signal line is not required, and the main board 271a and the initialization are performed. The circuit board 401 can be made compact.

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

  (A) In the above embodiment, the RAM 513 of the payout control device 311 is initialized together with the RAM 503 of the main control device 271 according to the operation of the RAM erasing switch 323. However, the RAM included in another control device is initialized. You may make it. In this case, the CPU 501 of the main control device 271 transmits an initialization command similar to the payout initialization command Cm to the control device.

  (B) In the above embodiment, the sealing unit 264 is provided as the trace remaining means, but other means may be adopted as long as some trace remains when the seal is released. As other means, for example, a seal sticker that is stuck across the box base 273A and the box cover 273B can be cited.

  (C) In the above embodiment, the initialization circuit board 401 and the main board 271 are located on the same plane. On the other hand, the initialization circuit board 401 and the main board 271 may be disposed on different surfaces. In this case, noise, heat, etc. from the initialization circuit board 401 side are more difficult to be transmitted to the main board 271 (particularly the CPU 501). As a result, a situation in which noise, heat, etc. adversely affect the main board 271 can be more reliably suppressed. Further, since at least a part of the substrates is arranged so as to overlap each other, the area efficiency is improved, and an increase in the area of the substrate box 273 can be suppressed.

  Further, one screw on the main control device (main board) 271 side is configured to be covered with the initialization circuit board 401, and the operation of the screw is practically impossible unless the initialization circuit board 401 is separated. It is good. With this configuration, it is possible to further prevent fraud.

  (D) In the above embodiment, the power failure monitoring circuit 542 and the RAM erasing switch circuit 543 are provided on the initialization circuit board 401, but at least one of them may be provided on the main board 271. The power failure monitoring circuit 542 may be provided on the power supply device (power supply board) 313 side.

  (E) You may implement as a pachinko machine etc. of a different type from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a game ball is awarded in a predetermined area after the big hit symbol is displayed. Furthermore, the present invention can be applied to a pachinko machine called a blade.

  (F) In addition to pachinko machines, the present invention can also be implemented as various gaming machines such as slot machines, arrange ball machines, and similar sparrow balls. The slot machine is a well-known machine in which, for example, a symbol is stopped and fixed by operating an operation lever in a state where a symbol effective line is determined by inserting coins. In this case, the game medium may be a coin, a medal or the like.

  (G) Furthermore, the present invention may be implemented as a gaming machine in which a pachinko machine and a slot machine are integrated. As a specific example, an identification information string composed of a plurality of identification information (specifically, a reel and identification information is a symbol attached to the reel) is variably displayed (specifically, a rotation of the reel). After that, variable display means for confirming and stopping the identification information is provided, and the fluctuation of the identification information is started due to the operation of the start operation means (for example, the operation lever), and the stop operation means (for example, the stop button) is operated. The special information that causes the special gaming state that is advantageous to the player on the condition that the change of the identification information is stopped due to the fact that it is the fixed identification information at the time of the stop or the specific identification information at the stop A game state generating means, using a game ball as a game medium, requiring a predetermined number of game balls at the start of variation of the identification information, and generating a large number of game balls at the occurrence of a special game state. One in which the ball is paid out.

  (H) The CPU and RAM may be configured separately.

  (I) In addition, guide means (for example, for making the plug-in connection of the connectors 273C and 401C more reliable when the illustration is omitted or when the box base 273A and the box cover 273B are slid to the inner side surfaces of the box base 273A and the box cover 273B, for example. (E.g., a U-shaped (tapered) guide rib) may be provided. In this case, it is desirable to provide the guide means on the side facing the connectors 271C, 401C (opposite side, near side) of the inner sides of the box base 273A and the box cover 273B. With such a configuration, it is difficult to hinder the substrate and the like, and the configuration can be simplified. Further, by providing such guide means in the connectors 271C and 401C themselves, the connectors 271C and 401C may be configured to be easily inserted and connected.
