Description

  The present invention relates to a gaming machine.

  Conventionally, a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) having a first symbol display device for displaying a first picture (so-called “special symbol”) is known. The first symbol display device variably displays the first symbol on the condition that a game ball is won at a predetermined winning opening, in order to teach a special gaming state advantageous to a player such as a jackpot and to enhance the interest of the game. Directing and so on. Some of these pachinko machines are provided with a second symbol display device for displaying a second symbol (so-called “ordinary symbol”). The second symbol display device variably displays the second symbol based on the result of the lottery performed on the condition that the game ball passes the predetermined gate, and the second symbol display device derives the predetermined display result. In such a case, the electric accessory provided at the predetermined winning opening is operated to open, and the game ball is likely to win the predetermined winning opening (see, for example, Patent Document 1).

When the game ball passes through the predetermined gate during the variable display of the second picture or the opening operation of the electric accessory, the passage is suspended up to a predetermined number of times (for example, four times) and is actually performed. If there is a hold when the variable display of the two patterns ends, the next variable display of the second pattern is performed based on the hold, and one hold is digested.
Similarly, when the game ball wins the predetermined winning opening during the variable display of the first picture, the winning is put on hold for a predetermined number of times (for example, four times) and is currently being performed. If there is a hold when the variable display of one pattern ends, the next variable display of the first pattern is performed based on the hold and one hold is digested.
Japanese Patent Laid-Open No. 2001-96004

However, when all the hold of the first design is digested, if all the hold of the second design has been digested, not only the variable display of the first design is interrupted, Since the opening operation cannot be expected, the player may feel frustrated.
In addition, if the second picture is always on hold by making it easier for the game ball to pass through the predetermined gate, the following various problems occur. That is, although the reserved number of the first pattern has reached the prescribed upper limit number, the electric accessory is opened, and a state where the game ball can easily win a predetermined winning opening is formed. At this time, even if the game ball wins a predetermined winning opening, the winning is not suspended and is wasted. Also, generally, when a game ball wins at the predetermined winning opening, the payout of the game ball is paid out according to the number of wins. If the number is increased, more prize balls will be paid out, causing a disadvantage to the game hall (a store where pachinko machines are installed).

  The present invention has been made in view of the above circumstances, and it is a main object of the present invention to obtain a gaming machine capable of easily winning a game ball in accordance with the reservation of the first picture.

  Hereinafter, effective means for solving the above-described object will be described while showing effects and the like as necessary.

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 the 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 game board 30 has 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, which will be described later, and predetermined on 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 bottom 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, the rail unit 50 is provided on the front side so that the out port 36 is closed). Shown in state). In addition, in order to disperse and adjust the falling direction of the game ball as appropriate, a large number of nails are implanted in the game board 30 and various members (functions) such as a windmill 37 are disposed.

  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, since the game ball intake port and the game board 30 do not overlap each other by lowering the game ball intake port, the notch for 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 operating 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. Occurs. Once the jackpot is generated, the variable winning device 32 is in a predetermined open state, and the game ball is easily won. As an opening mode of the variable 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 established, 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 gaming area on the gaming board 30 that is the maximum width reaches the left and right end positions of the gaming board 30. Among the parts corresponding to the ball guide passages of the rail unit 50, particularly with respect to the 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 as 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 winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning the 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 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 5, and the game discharged from the discharge ports 66 and 67 is in front of the pair. 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 substantially rectangular small window 78 at the lower right portion of the window hole 26. Accordingly, the stamp or the like attached to the lower right corner space (Sa in FIG. 4) of the game board 30 can be viewed through the small window 78. It is also possible to directly paste a stamp or the like on the game board 30 from the small window 78.

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. This small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, and through the relay terminal hole 59 and the small window 79, the relay installed on the back of the game board. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 5.

  In this configuration, various lamps provided on the front door frame 8 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 5 (resin base 25). 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 is 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 as to 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. When the key inserted into the keyhole is turned counterclockwise (counterclockwise direction), the main body frame 5 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 end portion and the lower end portion thereof, and the upper locking portion is locked to the main body frame 5 side, 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 cover member 92 constitutes the front portion of the pachinko machine together with the front door frame 8. 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 gaming area can be viewed from the front. The window portion 101 has a substantially oval shape close to a circle, 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 portion 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).

  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 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 which jumps out outside or a game ball will be 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 extending in an arc shape along the inner edge and protruding rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 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, with reference to FIG.6 and FIG.7, the structure of the back surface of the pachinko machine 1 is demonstrated.

  The overall outline of the back configuration of the pachinko machine 1 will be described.

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 to be detachable without using any tools or the like on a unit-by-unit basis, and are provided with a support shaft part in the main frame 5. 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 the first control board unit 201.

  As shown in FIG. 8, the first control board unit 201 is provided with a support shaft part M1 at the left end portion when viewed from the back of the pachinko machine 1, and the first control board unit 201 is formed by the support shaft part 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. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like on the left end 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 rotary 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, rotating the unit 201 around the axis A, and expanding the unit 201. 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.

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 configured to expand in opposite directions, the back pack unit 203 must be opened largely beyond a predetermined angle or the unit 203 must be removed. For example, the first control board unit 201 cannot be removed.

  Accordingly, when attention is paid to removing the first control board unit 201, it is difficult to remove compared to the other units 202 and 203. Furthermore, since the back pack unit 203 cannot be opened unless the main body frame 5 is opened with respect to the outer frame 3 by key operation of the locking device, the first control board unit 201 is further removed. Has become difficult. A more specific configuration will be described later.

  Next, the back surface structure of the main body frame 5 and the game board 30 is demonstrated.

  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 so as not to be unsealed by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

  As long as the sealing unit 274 is configured to connect the box base and the box cover so that they cannot be opened, any configuration can be applied. Here, as shown in FIG. 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 quickly 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 flat substrate mounting surfaces 252 and 253 are provided on the surface of the mounting base 251. These substrate mounting surfaces 252 and 253 extend in a direction perpendicular to the vertical and horizontal directions, 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 control device 271 is disposed on the horizontally long substrate mounting surface 252, and an audio lamp control device 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 places on the left and right. On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally operable fixtures 277 at two places on the left and right sides of the back surface thereof. When the main control device 271 is mounted on the substrate mounting surface 252, the main control substrate (main control device) 271 is placed so that the fixture 277 is inserted into the through hole 256 of the substrate mounting surface 252. The main controller 271 is locked by rotating the fixing tool 277 in the state. Accordingly, since 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, a deterrent effect such as board removal can be 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 steps in the front-rear direction, each control device 271, with the main control device 271 and the sound lamp control device 272 mounted on these substrate mounting surfaces 252 and 253, 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, it is possible to extend the main control device 271 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 to make each control device 271 and 272 efficient. 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.

The second control board unit 202 has a horizontally long mounting base 301 on which a payout control device 311, a firing control device 312, a power supply device 313 and a card unit connection board 314 are mounted. The payout control device 311 and the launch control device 312 are provided with a control board including a central control CPU, ROM, RAM, various ports, and the like. The payout control board of the payout control device 311 controls the payout of prize balls and rental balls, and the firing control board of the launch control device 312 controls the firing motor 229 according to the operation of the game ball launching handle 7 by the player. . In addition, a predetermined power supply voltage required by various control devices or the like is generated and output by the power supply board of the power supply device 313. The card unit connection board 314 is electrically connected to the ball lending operation unit 120 on the front surface of the pachinko machine and a card unit (not shown). The card unit connection board 314 mainly takes in a command for lending operation by a player and outputs it to the payout control device 311. In a cash machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, the card unit connection board 314 is unnecessary.

  The payout control device 311, the firing control device 312, the power supply device 313, and the card unit connection substrate 314 are configured to be accommodated in substrate boxes 315, 316, 317, and 318 made of a transparent resin material, respectively. In particular, in the payout control device 311, as with the main control device 271, the substrate box 315 constituting the enclosing means includes a box base and a box cover, and these are connected so as not to be opened by a sealing unit 319 as a sealing means, As a result, the substrate box 315 is sealed. The payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball clogging of a payout motor, which will be described later, the payout motor is rotated in the forward and reverse directions to eliminate the ball clogging (return to the normal state). It has become. The power supply device 313 is provided with a RAM erase switch 323. 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 at the time of recovery from the power failure (power recovery). It can be done. Therefore, for example, when the power supply is shut down by a normal procedure as in the case of the business hall being closed, the state before the power shut-off is stored and retained. However, if the power is turned on while pressing the RAM erase switch 323, the RAM data is initialized. It has become so.

  The mounting base 301 is made of, for example, a colorless and transparent resin molded product, and a flat board mounting surface 302 is provided on the surface thereof.

The protective cover portion 354 has a shape in which the left and right side surfaces and the upper surface are closed and only the lower surface is opened, and has a size sufficient to surround at least the variable display unit 35. However, in this configuration, the above-described sound lamp control device 272 is also enclosed. A large number of ventilation holes 354a are provided on the back surface of the protective cover portion 354. Each of the ventilation holes 354a is formed in a long hole shape, and the ventilation holes 354a are adjacent to each other at relatively close positions. Therefore, the back surface of the back pack 351 can be easily opened by cutting the resin portion between the adjacent vent holes 354a. That is, a predetermined test or the like can be easily performed by cutting the resin portion between the vent holes 354a to expose the display control device 214 and the like inside.

  A payout mechanism portion 352 is disposed on the base portion 353 of the back pack 351 so as to bypass the protective cover portion 354. That is, a tank 355 that opens upward is provided at the top of the back pack 351, and game balls supplied from the island facilities of the game hall are sequentially replenished to the tank 355. Below the tank 355, for example, tank rails 356 having two rows (two rows) of spherical passages and gently inclined toward the downstream side are connected. The tank rails 356 extend in the vertical direction on the downstream side. A case rail 357 is connected. The payout device 358 is provided at the most downstream portion of the case rail 357, and the payout motor 358a is driven by the control of the payout control device 311 so that a required number of game balls are paid out appropriately.

Although not shown, a tank ball absence sensor that detects the presence or absence of a game ball supplied from the tank 355 or the tank rail 356 is provided upstream of the case rail 357. The payout device 358 is provided with a payout rotation sensor that detects the rotation of the payout motor 358a and a payout count switch that counts the number of game balls to be paid out.

  A vibrator 360 for attaching vibration to the tank rail 356 is attached to the tank rail 356. The vibrator 360 is unitized by a vibrator motor and a synthetic resin case that accommodates the vibrator motor, and is attached to the tank rail 356 by two legs 360a. Therefore, if a clogged ball occurs near the tank rail 356, the clogged ball is eliminated by driving the vibrator 360.

  The structure of the tank rail 356 will be described in detail. As shown in FIG. 22, the tank rail 356 has a rail body 361 having a long bowl shape opened upward. A spherical ball receiving portion 362 is formed in the upstream portion of the rail main body 361 so that the game ball dropped from the tank 355 by the ball receiving portion 362 is smoothly taken into the rail main body 361. The rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. The bottom surface of each spherical passage partitioned by the partition wall 363 is provided with one or two ridges 364 and an opening 365 for dropping dust to the side of the ridges 364. ing. The rail body 361 is provided with a rectifying plate 367 so as to cover a ceiling portion of about half of the downstream side, and the rectifying plate 367 is bowed so as to limit the height of the ball passage in the tank rail 356 toward the downstream side. A convex portion 368 extending in the longitudinal direction is formed on the lower surface thereof. Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even if a large amount of game balls flow into the tank rail 356, the game balls are prevented from being bitten and the ball clogging in the tank rail 356 is difficult to occur. The rail body 361 is formed of a black conductive polycarbonate resin to prevent electrification, while the rectifying plate 367 is formed of a transparent polycarbonate resin so that a ball clogging or the like can be visually confirmed. The rectifying plate 367 is detachably provided. By removing the rectifying plate 367, maintenance in the tank rail 356 can be easily performed.

  The RAM erase switch circuit 543 receives the switch signal of the RAM erase switch 323, and outputs a RAM erase signal SG2 for clearing the backup data of the main controller 271 and the payout controller 311 according to the state of the RAM erase switch 323. Circuit. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SG2 to the main controller 271 and the payout controller 311. Thereby, when the power of the pachinko machine 1 is turned on while the RAM erase switch 323 is pressed, the data in the respective backup areas 503a and 513a is cleared in the main controller 271 and the payout controller 311.

  Next, the structure concerning the display control of the first symbol (special symbol) of the display control device 214 will be described with reference to FIG.

  As shown in FIG. 24, the display control device 214 includes a CPU (MPU) 521, a program ROM 522, a work RAM 523, a video display processor (VDP) 524, a video RAM 525, a character ROM 526, and an input port 527. The CPU 521 of the display control device 214 receives the symbol display command output from the main control device 271 via the input port 527, analyzes the symbol display command, or performs predetermined arithmetic processing based on the symbol display command. To control the VDP 524 (specifically, generation of an internal command for the VDP 524).

  The program ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and also stores and holds JPEG format image data for background images. The work RAM 523 is a memory for temporarily storing work data, flags, and the like used when the CPU 521 executes various programs.

  The video RAM 525 is a memory for storing display data displayed on the first symbol display device 41, and the display contents of the first symbol display device 41 are changed by rewriting the contents of the video RAM 525. The character ROM 526 plays a role as an image data library for storing display data such as symbols displayed on the first symbol display device 41 and images used for a notice effect. The character ROM 526 holds bitmap format image data of various display patterns, a color palette table to be referred to when determining the expression color of each dot of the bitmap image, and the like. In particular, a symbol code (symbol number) is assigned to each symbol image data in the bitmap format, and each symbol image can be managed only by the symbol code at the command level. Note that a plurality of character ROMs 526 may be provided, and image data and the like may be stored in each character ROM 526 in a shared manner. Further, it is also possible to store the JPEG format image data for the background image stored in the program ROM 522 in the character ROM 526.

  The VDP 524 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal driving circuit) incorporated in the first symbol display device 41. Since the VDP 524 is formed as an IC chip, it is also called a “drawing chip”, and the substance of the VDP 524 can be said to be a microcomputer chip with a dedicated firmware for drawing processing. The VDP 524 adjusts the timing of the CPU 521, the video RAM 525, etc., and intervenes in reading and writing display data. That is, the VDP 524 reads image data from the character ROM 526 at a predetermined timing based on the control of the CPU 521, generates display data that is a display image, and writes the display data to the video RAM 525. The display data written in the video RAM 525 is finally read by the VDP 524, and when the VDP 524 operates the LCD driver based on the display data, a display screen based on this display data is displayed on the first symbol display device 41. The

  Next, display contents on the display screen in the first symbol display device 41 will be described. FIG. 25 shows the effective line setting in the display screen G of the first symbol display device 41, and FIG. FIG. 27 is a diagram showing a display example in which the first symbol is inserted into the display screen G.

  As shown in FIG. 25, the display screen G of the first symbol display device 41 is virtually divided into three columns, and three display areas for displaying the first symbol are provided. The left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 are displayed in order. As shown in FIG. 26, each symbol row Z1 to Z3 includes 10 main symbols each having a numeric number from 0 to 9, and sub symbols arranged between the main symbols (in the illustrated example, a star mark “☆”). In particular, the number of the main symbols is arranged in descending order in the left symbol row Z1, and the number of the main symbols in the middle symbol row Z2 and the right symbol row Z3. Are arranged in ascending order. On the display screen G, the 20 first symbols are variably displayed in the symbol rows Z1 to Z3 so as to scroll vertically from top to bottom (indicated by arrow A in FIG. 25). In addition, on the display screen G, the first symbols are displayed in the upper, middle, and lower three rows in each of the symbol rows Z1 to Z3. As a result, as shown in FIG. A symbol is displayed.

  With this display mode, as shown in FIG. 25, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set on the display screen G. . Then, in one cycle from the start of variable display of the first symbol to the stop display, the variable display (scroll display) of the first symbol is stopped in the order of the left symbol column Z1, the right symbol column Z3, and the middle symbol column Z2. A special game that is advantageous to the player when a combination of jackpot symbols on any active line (in this embodiment, a combination of the same main symbols) is a big hit when the symbols Z1 to Z3 are stopped and displayed. A condition occurs.

  Specifically, in the pachinko machine 1, the main symbol to which the odd number (1, 3, 5, 7, 9) is assigned corresponds to the “high probability symbol”, and the high probability symbol corresponds to the above five effective lines. By matching to any one of L1 to L5, a big hit state, which is a special gaming state, is entered, and then the state shifts to a high probability state. In addition, the main symbol to which the even number (0, 2, 4, 6, 8) is assigned corresponds to the “low probability symbol”. It does not transition to a high probability state. From the above, the main symbol is provided with a numeric number as an identification unit for teaching the presence or absence of probability fluctuation after the big hit state. The high probability state refers to a state in which the combination of the first symbol becomes a big hit by a predetermined combination of probability variation symbols, and the subsequent jackpot probability is increased as added value, that is, a so-called probable change. (Probability state) refers to a time when such a probability variation state is not present.

  Further, in the pachinko machine 1, the fluctuation of the first symbol and the second symbol during the high probability state and after the transition to the low probability state through the high probability state until the jackpot lottery reaches a predetermined number of times. The time from the start to the confirmation display is shortened. In the following description, a gaming state in a high probability state is referred to as a probability variation gaming state, and is a gaming state in a low probability state, and the time from the start of change of the first symbol and the second symbol to the final display is shortened. The gaming state is referred to as a short-time gaming state, and a gaming state that is a low probability state and other than the short-time gaming state is referred to as a normal gaming state.

  Next, a configuration relating to display control of the second symbol (for example, “O” or “x” ordinary symbol) will be described. As shown in FIG. 24, the second symbol display device 42 that displays the second symbol is displayed by the display control device 214 in the same manner as the first symbol display device 41. Specifically, the CPU 521 of the display control device 214 receives a normal symbol display command related to the normal symbol display control from the main control device 271 via the input port, analyzes the normal symbol display command, and displays the second symbol display. The change display of the 2nd symbol in the apparatus 42 is implemented. Specifically, the display control device 214 controls the second symbol display device 42 when receiving a second symbol variation pattern command for instructing the second symbol variation start and variation pattern (described later) from the main control device 271. Then, “○” and “×” are alternately lit and displayed as the normal symbol variation display, and then the second stop symbol command for instructing the second symbol at the final display, and the second symbol confirmation display are instructed. When the second symbol confirmation command is received, the second symbol (“◯” or “x”) is confirmed and displayed. In the present embodiment, the second symbol “◯” corresponds to the winning symbol, and when the second symbol is confirmed and displayed, the electric accessory provided to the operating port 33 is opened.

  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, symbol display on the first symbol display device 41, symbol display setting on the second symbol display device 42, and the like. To do. First, the jackpot lottery and the setting of the symbol display of the first symbol display device 41 will be described in detail. As shown in FIG. 28, the jackpot random number counter C1 used for the jackpot lottery and the jackpot symbol of the first symbol display device 41 are displayed. A jackpot symbol counter C2 used for selection, a reach random number counter C3 used for reach lottery when the first symbol display device 41 moves out and fluctuates, and a random number initial value counter CINI used for setting an initial value of the jackpot random number counter C1 , Variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, and left, middle and right outlier symbol counters CL used for setting each outlier symbol in the left column, middle column and right column , CM, and CR are used.

  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. According to the winning history, 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.

  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 0 to 676, for example, and returns to 0 after reaching the maximum value (ie, 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. Note that the random number initial value counter CINI is a loop counter similar to the big hit 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 a 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. That is, the jackpot symbol counter C2 is incremented by 1 within a range of 0 to 49, and reaches a maximum value (that is, 49) and then returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by one before and after the reach symbol, and the last stop symbol after the reach has also occurred. “Reach other than front / rear out” and stop “completely out” where no reach occurs, 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.

  Left, middle, and right out 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 in total including the main symbol and the sub symbol is displayed, 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 completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case.

  Next, the symbol display setting of the second symbol display device 42 will be described in detail. As shown in FIG. 29, in the present embodiment, when the main controller 271 performs display setting of the second symbol, a lottery is selected to determine whether or not the operation of opening the electric accessory provided incidentally to the operating port 33 is possible. The 2 symbol random number counter C4 and the second symbol random number initial value counter CINI ′ used for setting the initial value of the second symbol random number counter C4 are used. Each of the second symbol random number counter C4 and the second symbol random number initial value counter CINI 'is a loop counter that adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value. These counters C4 and CINI 'are updated at short time intervals, and the updated values are appropriately stored in a second symbol counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a second symbol holding area composed of one execution area and four holding areas (first to fourth normal symbol holding areas) for the second symbol as well as the first symbol. In each of these areas, the value of the second symbol random number counter C4 is stored in time series in accordance with the passing history of the through ball 34 of the game ball.

  The second symbol random number counter C4 will be described in detail. The second symbol random number counter C4 is configured as a loop counter that is incremented by 1 in the range of 0 to 250, for example, and returns to 0 after reaching the maximum value (ie, 250). Has been. In particular, when the second symbol random number counter C4 makes one round, the value of the second symbol random number initial value counter CINI 'at that time is read as the initial value of the second symbol random number counter C4. The second symbol random number initial value counter CINI ′ is a loop counter similar to the second symbol random number counter C4 (value = 0 to 676), and is updated once every timer interrupt and the remaining time of normal processing Updated repeatedly. The second symbol random number counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”. Note that the sizes and ranges of the second symbol random number counter C4 and the second symbol random number initial value counter CINI 'are merely examples, as in the above-described counters, and can be arbitrarily changed.

  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. 37 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 271 every 2 msec, for example. 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 S801). 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 and the second symbol random number initial value counter CINI 'are updated (step S802). Specifically, each of the random number initial value counter CINI and the second symbol random number initial value counter CINI ′ is incremented by “1”, and when the counter value reaches the maximum value (676 in the present embodiment), “ Clear to "0". Then, the updated values of the random number initial value counter CINI and the second symbol random number initial value counter CINI ′ are stored in the corresponding buffer area of the RAM 503. Subsequently, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the second symbol random number counter C4 are updated (step S803). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the second symbol random number counter C4 are incremented by “1”, respectively, and the counter values are maximum values (in the present embodiment, respectively). , 676, 49, 238, 251), each is cleared to “0”. Then, the updated values of the counters C1 to C4 are stored in the corresponding buffer area of the RAM 503.

  Next, a start winning process is performed in accordance with the winning of a game ball to the operation port 33 (step S804). The start winning process will be described with reference to the flowchart of FIG. 38. 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 S901). If 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 S902). ). The process proceeds to step S903 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 S803 are stored in the first area of the free storage area of the reserved ball storage area of the RAM 503 (step S904).

  In addition, when the game ball wins the operating port 33 (start winning prize), the first symbol display display on 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 the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S904). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses). .

  Returning to FIG. 37 again, after that, the CPU 501 executes a through gate passing process accompanying the passing of the through ball 34 of the game ball (step S805). The through-gate passing process will be described with reference to the flowchart of FIG. 39. First, it is determined from the detection information of the gate switch 225 whether or not the game ball has passed through the left or right through gate 34 (step S1001). When it is determined that the game ball has passed through the through gate 34, it is determined whether or not the number M of active suspension balls of the second symbol display device 42 is less than the upper limit value (4 in the present embodiment) (step S1002). ). The processing step proceeds to step S1003 on the condition that the through gate 34 has passed and the number of operation reservation balls M <4, and the operation reservation ball number M is incremented by “1”. Subsequently, the value of the second symbol random number counter C4 updated in step S803 is stored in the first area among the free storage areas of the second symbol holding area of the RAM 503 (step S1004). After the through gate passing process, the CPU 501 once ends this timer interrupt process.

  FIG. 40 is a flowchart showing the NMI interrupt process. This process 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, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 40 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt processing, the CPU 501 of the main control device 271 saves the used registers in the backup area 503a of the RAM 503 (step S1101), and stores the stack pointer value in the backup area 503a (step S1102). Further, the occurrence information of the power shutdown is set in the backup area 503a (step S1103), and a power shutdown notification command indicating that the power is shut off is output to another control device (step S1104). The RAM determination value is calculated and stored in the backup area 503a (step S1105), and the RAM access is prohibited (step S1106). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Thereafter, an infinite loop is entered in preparation for the power supply being completely shut down and the processing being impossible.

  The above NMI interrupt processing is executed in the same manner 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 513a 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 to the NMI terminal of the CPU 511 in the payout controller 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 40 is started. The contents are the same as described above, except that the power-off notification command is not output in step S904.

  FIG. 30 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 271, and this main process is started upon a reset when the power is turned on. In 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, a payout permission command is output to the payout control device 311 (step S102), and RAM access is allowed (step S103).

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (step S104). If the RAM erase switch 323 is not pressed (step S104: NO), then the backup area of the RAM 503 is continued. It is determined whether or not the occurrence information of power shutdown is set in 503a (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 a RAM initialization process (steps S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (steps S114 to S116) of the RAM 503 in the same manner. . In the initialization process of the RAM 503, first, the used area of the RAM 503 is cleared to “0” (step S114), and the initialization process of the RAM 503 is executed (step S115). Then, after setting the interrupt permission (step S116), the routine proceeds to normal processing described later.

  On the other hand, when the RAM erase switch 323 has not been pressed (step S104: NO), the occurrence information of the power shutdown is set (step S105: YES), and the RAM judgment value (checksum value etc.) On condition that it is normal (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, each time the normal process is performed 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.

  Further, in step S201, the second symbol change pattern command, the second stop symbol command, and the second symbol confirmation command are output to the display control device 214 when the second symbol display device 42 displays the variation of the second symbol. When starting the variation of the second symbol, the command is output one by one for each normal process in the order of the second symbol variation pattern command → the second stop symbol command (that is, one every 4 msec), and the variation time The second symbol confirmation command is output at the elapse timing.

  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 out 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 out 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 update time of the left symbol row (step S301: YES), the processing procedure proceeds to step S303, and the left symbol row outlier counter CL is updated. If it is the update time of the middle symbol sequence (step S302: YES), the processing procedure proceeds to step S304, and the out symbol counter CM of the middle symbol sequence 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 row (both steps S301 and S302 are NO), the processing procedure proceeds to step S305 and the right symbol row out of symbol counter CR is updated. . In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value. 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 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 symbol counters CL, CM, and CR are updated for one set.

  Thereafter, it is determined whether or not the combination of the updated out symbol counters CL, CM, and CR is a jackpot symbol combination (step S306). If it is a jackpot symbol combination (step S306: YES), the book 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, CR are a combination of front and rear outreach (step S308: YES), the combination of out symbol symbols CL, CM, CR at that time is stored in the front and rear outreach 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, CR is not the combination of the jackpot symbol and the combination of the reach symbols (when both S306 and S307 are NO), this is the case of the off symbol counters CL, CM, CR. The combination corresponds to a combination of out-of-designs. In such a case, the combination of out-of-design counters CL, CM, and CR at that time is stored in the complete out-of-design symbol buffer of 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, setting of a variation pattern 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 special winning opening opening / closing process for opening or closing the special winning opening of the variable winning apparatus 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 in the big win 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). Details of the second symbol variation process will be described later.

  Thereafter, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process (step S208). If the predetermined time has not yet elapsed (step S208: NO), the random number initial value counter CINI, the second symbol random number initial value counter CINI ′, and the variation type within the remaining time until the next normal processing execution timing is reached. The counters CS1 and CS2 and the left / middle / right outlier 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 and the second symbol random number initial value counter CINI 'are updated. Specifically, the random number initial value counter CINI and the second symbol random number initial value counter CINI ′ are incremented by “1”, and when the counter value reaches the maximum value (676 in the present embodiment), “0”. To clear. Then, the updated values of the random number initial value counter CINI and the second symbol random number initial value counter CINI ′ are 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 outlier 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, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) and the random number initial value counter CINI and the second symbol random number initial value counter CINI ′ are repeatedly updated using the remaining time. The second symbol random number initial value counter (that is, the initial value of the second symbol random number counter C4) can be updated at random. Similarly, the variation type counters CS1 and CS2 and the left, middle and right outlier symbol counters CL, CM, and CR can 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). Note that 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, when the jackpot is not being hit and the variation of the first symbol is not being displayed (both steps S401 and S402 are NO), the processing procedure is advanced to step S403, and the number N of active suspended balls of the first symbol display device 41 is “0”. It is discriminated whether or not it is larger. 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), it is not necessary to perform the variable display of the first symbol. Exit.

  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 for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, the first symbol variation start process is executed (step S406). Here, the details of the first symbol variation start process will be described with reference to the flowchart of FIG. 34. The CPU 501 in the main controller 271 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 it is a big hit (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 the game is a big hit (step S501: YES), the first symbol corresponding to the value of the big jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the big jackpot symbol (the jackpot symbol) A table representing the correspondence between the value of the counter C2 and the first symbol), and the first 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. When these jackpot symbols are aligned with a predetermined specific symbol (the main symbol of the first symbol), the process shifts to a probabilistic state. Does not enter a probabilistic 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 design 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 a 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”, of 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 reach has occurred 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 forward / backward 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.

  Next, the second symbol variation process of step S207 will be described with reference to the flowcharts of FIGS. In this second symbol variation process, the value of the second symbol random number counter C4 is acquired each time on the condition that the game ball has passed through the through gate 34, and the second symbol display device 42 Variable display of symbols is performed. In addition to this, in this embodiment, in the second symbol variation process, during the gaming state in which the time from the start of variation of the second symbol to the fixed display is shortened, that is, during the probability variation gaming state or the short-time gaming state, The variable display time is made variable in accordance with the number N of reserved balls in the first symbol.

  The second symbol variation process will be described in detail. As shown in FIG. 35, the CPU 501 in the main control device 271 is currently operating to release the electric accessory attached to the operation port 33. It is determined whether or not (step S601). Subsequently, it is determined whether or not the second symbol display device 42 is displaying the variation of the second symbol (step S602). Then, when the opening of the electric accessory is not being performed and the variation of the second symbol is not being displayed (NO in both steps S601 and S602), the processing procedure proceeds to step S603, and the number of suspended operation balls of the second symbol display device 42 It is determined whether or not M is larger than “0”. On the other hand, if the opening operation is being performed (step S601: YES), or if the number M of suspended operation balls M of the second symbol display device 42 is “0” (step S603: NO), the second symbol variation display is performed. Since there is no need, this processing is terminated.

  On the other hand, if neither the opening operation of the electric accessory or the variation display of the second symbol is being displayed, and if the number of operation suspension balls M> 0 of the second symbol display device 42 is greater than (NO in step S602, And step S603 is YES), the number M of operation reservation balls is decremented by "1" (step S604), and the process which shifts the data stored in the 2nd symbol reservation area is performed (step S605). This data shift process is a process of shifting the data stored in the first to fourth normal symbol holding areas of the second symbol holding area to the execution area side, the first normal symbol holding area → the execution area, the first 2 Normal symbol hold area → 1st normal symbol hold area, 3rd normal symbol hold area → 2nd normal symbol hold area, 4th normal symbol hold area → 3rd normal symbol hold area, etc. Shifted.

  Thereafter, the variation start process of the second symbol is executed (step S606). The details of the second symbol variation start process will be described using the flowchart shown in FIG. 36. The CPU 501 in the main controller 271 sets the value of the second symbol random number counter C4 stored in the execution area of the second symbol hold area. Based on this, it is determined whether or not it is a win (step S701). As described above, “5-153” is the winning value among the numerical values “0-250” of the second symbol random number counter C4.

  If the winning symbol is determined (step S701: YES), the second symbol corresponding to the winning symbol (“◯” in this embodiment) is set as the second stop symbol command (step S702), and the symbol is not winning. Is determined (step S701: NO), the second symbol ("X" in the present embodiment) corresponding to the lost symbol is set as the second stop symbol command (step S703). When the second symbol (“◯”) indicating the winning is confirmed and displayed on the second symbol display device 42, the electric accessory provided incidentally to the operation port 33 is opened. The operation release time differs depending on the game state at that time, and the operation release time is set longer in the probability variation game state and the short-time game state than in the normal game state and the jackpot game state. The operation release time in the jackpot game state is, for example, 0.2 seconds, and the operation release time in the probability variation game state and the short-time game state is, for example, 1.84 seconds. In addition, the number of times of operation release per winning is also different depending on the game state at that time, and the number of operation release times is set more in the probability variation game state and the short-time game state than in the normal game state and jackpot game state, The number of operation releases in the normal game state and the jackpot game state is one, and the number of operation releases in the probability variation game state and the short-time game state is three. When a predetermined number (for example, four) of game balls wins the operation opening 33 within the operation release time, the electric accessory is closed even if the operation release time has not elapsed. Moreover, the said operation | movement open time and the frequency | count of operation | movement opening are only illustrations to the last, and can be changed suitably.

  Next, in steps S704 to S709, a second symbol variation pattern that defines a variation pattern until the second symbol is fixedly displayed is determined, and the second symbol variation pattern is set in the second symbol variation pattern command. In the present embodiment, any one of the second symbol variation patterns A1 to A3 having different second symbol variation display times is set as the second symbol variation pattern. The variable display time here refers to the time from the start of variable display of the second symbol to the final display.

  The second symbol variation pattern A1 is a variation pattern set when the gaming state is a normal gaming state and a jackpot gaming state. The variation display time of the second symbol designated by this variation pattern is the second symbol variation pattern. It is set to be the longest among A1 to A3 (for example, 28.5 seconds). The second symbol variation patterns A2 and A3 are variation patterns that are alternatively set when the gaming state is the probability variation gaming state and the short time gaming state. The variation display time designated by the second symbol variation pattern A2 is set longer than that of the second symbol variation pattern A3. For example, the variation display time of the second symbol variation pattern A2 is 4 seconds, and the second symbol variation pattern A3 Is 1.5 seconds. These fluctuation display times are merely examples, and as long as the fluctuation display time becomes shorter in the order of the second symbol fluctuation pattern A1, the second symbol fluctuation pattern A2, and the second symbol fluctuation pattern A3, the fluctuation display times thereof. It is possible to use an appropriate value as In this way, in the probability variation gaming state and the short-time gaming state, the retention of the second symbol is faster than in the normal gaming state, so that the trigger for the opening operation of the electric accessory increases. Since the time is extended, it becomes very easy for the game ball to win the operating port 33, and the retention rate of the first symbol is also increased, so that the chance of fluctuation of the first symbol can be greatly increased.

  In step S704, the CPU 501 determines whether the current gaming state is the probability variation gaming state or the short-time gaming state, and if it is not the probability variation gaming state or the time-short gaming state (step S704: NO), the second symbol variation pattern described above. A1 is set to the second symbol variation pattern command (step S705). On the other hand, if the current gaming state is the probability variation gaming state or the short-time gaming state (step S704: YES), in steps S706 to S709, one of the second symbol variation patterns A2 and A3 is selected and the second Set to the symbol variation pattern command.

  Which of the second symbol variation patterns A2 and A3 is to be selected is based on the current number N of the pending operation balls of the first symbol display device 41. That is, the CPU 501 determines whether or not the current number N of the operation reservation balls of the first symbol display device 41 is relatively large and is equal to or greater than a predetermined number Na (for example, Na = 3) (step S706). If the number N of operation-reserved balls of the symbol display device 41 is equal to or greater than the predetermined number Na (step S706: YES), the second symbol variation pattern A2 having a long variation display time is selected, and the second symbol variation pattern A2 is selected as the second symbol variation pattern A2. A symbol variation pattern command is set (step S707). On the other hand, if the number N of currently active balls of the first symbol display device 41 is relatively small and not more than the predetermined number Na (step S706: NO), on the condition that a game ball has been launched ( Step S708: YES), the second symbol variation pattern A3 having the shortest variation display time is set in the second symbol variation pattern command (Step S9). Further, when the game ball is not launched (step S709: NO), even if the number N of the operation holding balls of the first symbol display device 41 is small, the second that has a relatively long variable display time. The symbol variation pattern A2 is set in the second symbol variation pattern command (step S707). The determination as to whether or not a game ball has been launched is made based on detection information of the handle sensor 600 that detects that the player is touching the game ball launching handle 18. Not only the detection information of the handle sensor 600 but also a sensor for detecting the passage of the game ball is provided in the out port 36 through which the launched game ball is discharged from the game board 30, and the detection information of the sensor It is good also as a structure which judges launch of a game ball using the sensor which provided the sensor which detects passage of a game ball in the site | part (upper left part of FIG. 4) where the game ball jumps out in the rail unit 50, and the detection of the said sensor A configuration may be adopted in which the launch of a game ball is determined using information. As described above, when the setting of the second stop symbol command and the second symbol variation pattern command is completed, this process ends.

  Subsequently, returning to FIG. 35, if step S602 is YES, that is, if the variation of the second symbol is being displayed, whether or not the variation display time designated by the second symbol variation pattern command of the variation has elapsed. A determination is made (step S607). When the variable display time has elapsed (step S607: YES), the second symbol confirmation command set for the confirmation display of the second symbol is set (step S608), and then this process ends.

  The command to be output to the second symbol display device 42 is set by the second symbol variation display process described above. Then, the display control device 214 controls the second symbol display control device 42 according to these commands, and the second symbol variation display is performed. Specifically, the display control device 214 CPU 521 executes display control of the second symbol display device 42 according to the procedure shown in FIG.

  That is, the CPU 521 of the display control device 214 determines whether or not the second symbol display command (second symbol variation pattern command, second stop symbol command, second symbol confirmation command) is input from the main control device 271 (step). S1701). If the determination result is NO, the system waits for some command to be input. When the second symbol display command is input, the contents of the second symbol display command are stored in the work RAM 523 (step S1702). Subsequently, based on the information stored in the work RAM 523, the second symbol display on the second symbol display device 42 is started to be displayed (step S1703). Note that once the second symbol display command is input, the variation display of the second symbol is continued until the second symbol confirmation command is input thereafter.

  Thereafter, it is determined whether or not a second symbol confirmation command has been input from the main controller 271 (step S1704). Then, the processing procedure is advanced to step S1705 on the condition that the second symbol confirmation command is received, and the second symbol display device 42 is instructed to confirm the display with the stopped symbol. As a result, the second symbol display device 42 displays the fluctuating symbol on the second symbol (“◯” or “x”) designated by the second stop symbol command. Thus, one round of display processing from the start of change of the second symbol to the stop of change (definite display) is performed. When the second symbol “◯” indicating the winning is confirmed and displayed on the second symbol display device 42, the electric accessory provided in the operation port 33 is opened.

  In particular, in the present embodiment, in the probability variation gaming state or the short time gaming state, when the number N of actuated balls of the first symbol display device 41 is equal to or greater than a predetermined number Na (for example, Na = 3), the variable display time is relatively long. If the long second symbol variation pattern A2 is selected, and the number N of operation reservation balls of the first symbol display device 41 is less than the predetermined number Na, the second symbol variation pattern A3 having a relatively short variation display time is selected. As a result, when the number N of the operation reservation balls of the first symbol display device 41 is relatively large, the variation display time of the second symbol becomes long. In the case where the number N of actuated balls to be held in the symbol display device 41 is relatively small, the change display time of the second symbol is shortened, so that the digestion of the symbols is relatively quick. Therefore, when the number N of the operation reservation balls of the first symbol display device 41 is reduced, the time until the electric accessory provided in the operation port 33 is opened next is shortened. Become.

  Therefore, when the number N of the operation reservation balls of the first symbol display device 41 decreases and the variation display of the first symbol is about to be interrupted, the time until the next opening operation of the electric accessory is shortened, and the operation port 33 A situation in which a winning of a game ball is likely to occur is quickly formed. Thereby, the number N of operation reservation balls of the 1st symbol display device 41 increases, and it is prevented that the variable display of the 1st symbol (special symbol) in the 1st symbol display device 41 is interrupted every time.

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

  First, the CPU 511 executes an initial setting process associated with power-on (step S1201). Specifically, a predetermined value determined in advance is set in the stack pointer, and an interrupt mode is set. Next, the process waits until a payout permission command output from the main controller 271 is input (step S1202). Then, when the payout permission command is input, the processing procedure proceeds to step S1203 and RAM access is permitted, and an external interrupt vector is set in step S1204.

  Thereafter, data backup processing is executed for the RAM 513 in the CPU 511. That is, in step S1205, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed, and in subsequent step S1206, it is determined whether or not the information on occurrence of power shutdown is set in the backup area 513a of the RAM 513. To do. In step S1207, a RAM determination value is calculated. In subsequent step S1208, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is a checksum value at a work area address in the RAM 513, for example. Note that it is possible to determine the validity of the backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If the RAM erase switch 323 has been pressed, the process proceeds to a RAM initialization process (steps S1215 to S1218). Similarly, when the information on occurrence 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 513 (steps S1215 to S1218). . That is, in step S1215, the entire area of the RAM 513 is cleared to “0”, and in the subsequent step S1216, initialization processing of the RAM 513 is executed. In step S1217, the CPU peripheral device is initialized, and in step S1218, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when power is restored). That is, in step S1209, the stack pointer before the power shutdown is restored, and in step S1210, the information on the occurrence of power shutdown is cleared. In step S1211, the CPU peripheral device is initialized, and in step S1212, the register used is restored from the backup area 513a of the RAM 513. Further, in steps S1213 and S1214, the interruption permission / non-permission is returned to the state before the power interruption, and then the address before the power interruption is returned.

  Next, the flow of 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. 42, 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 S1301). Next, launch permission is set for the launch controller 312 (step S1302). 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 S1303).

  Thereafter, the setting of the lower plate full state or the lower plate full state is performed according to the change in the state of the lower plate 13 (step S1304). That is, when the lower pan 13 is determined to be full based on the detection signal of the lower pan full switch, the lower pan full state is set when the lower pan is full, and the lower pan is no longer full. , Set the lower pan full release state. Next, in accordance with the change in the state of the tank ball, the setting of the tank ball absence state or the tank ball absence release state is executed (step S1305). In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch. When there is no tank ball, the tank ball no state setting is executed. Perform configuration.

  Thereafter, the presence / absence of the state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified (step S1306). Next, in steps S1307 to S1309, prize ball payout processing is executed. That is, it is determined whether or not the prize balls cannot be paid out (step S1307). If the prize balls cannot be paid out, it is determined whether or not the total number of prize balls stored in step S1301 is “0” (step S1307). Step S1308). If the prize ball is not paid out and the total number of prize balls is not “0” (both NO in steps S1307 and S1308), a prize ball control process described later shown in FIG. 43 is started (step S1309). 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 S1307 or S1308), the process proceeds to the lending payout process shown in steps S1310 to S1312.

  In the lending payout process, it is first determined whether or not the lending state of the lending is disabled (step S1310). If it is not disabled (step S1310: NO), a lending payout request from the card unit is determined. It is determined whether or not is input (step S1311). Then, if a ball rental payout request is input (S1311: YES), a ball rental control process described later shown in FIG. 44 is started (step S1312). On the other hand, if a rental ball payout disabled state or a rental ball payout request has not been input (YES in step S1310 or NO in step S1311), 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 payout motor 358a on the condition that the ball removal is not disabled and the ball removal operation is not started (step S1313). Subsequently, the control of vibrator 360 (vibration motor control) is executed on the condition that the ball is clogged (step S1314). Thereafter, the process returns to the top of the payout control process.

  Here, in the winning ball control process shown in FIG. 43, the payout motor 358a is driven to execute paying out a winning ball (step S1401). Subsequently, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (step S1402). If the rotation of the payout motor 358a is not normal (step S1402: NO), the payout motor 358a is driven to execute the retry process and the payout motor 358a is stopped (step S1403), and then the payout shown in FIG. Return to control processing.

  If the rotation of the payout motor 358a is normal (step S1402: YES), it is determined from the detection result of the payout count switch whether the game ball is normally counted (step S1404). If the game ball count is not normal (step S1404: NO), the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped (step S1405), and then the payout control of FIG. Return to processing.

  On the other hand, if the game ball count is normal (step S1404: YES), it is determined whether or not the game ball count by the payout count switch has reached the total number of winning balls and payout has been completed (step S1406). If the payout has been completed (step S1406: YES), the payout motor 358a is stopped in step S1407, and then the payout control process in FIG. 42 is returned to.

  In the ball rental control process shown in FIG. 44, the payout motor 358a is driven to pay out a ball (step S1501). Subsequently, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (step S1502). If the rotation of the payout motor 358a is not normal (step S1502: NO), the payout motor 358a is driven to execute the retry process and the payout motor 358a is stopped (step S1503), and then the payout shown in FIG. Return to control processing.

  If the rotation of the payout motor 358a is normal (step S1502: YES), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (step S1504). If the game ball count is not normal (step S1504: NO), the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped (step S1505), and then the payout control of FIG. Return to processing.

  Further, if the game ball count is normal (step S1504: 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 S1506). If the payout has been completed (step S1506: YES), the payout motor 358a is stopped (step S1507), and then the process returns to the payout control process of FIG.

  Next, a specific procedure of display control related to the first symbol variation display by the display control device 214 will be described. FIG. 45 is a flowchart of 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 controller 271 (step S1601). 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 S1602). 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 S1603). As a result, the VDP 524 performs a drawing process in response to 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 the voices and the lamps to the voice lamp control device 272 while synchronizing 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. 45 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 S1604). Then, the processing procedure is advanced to step S1605 on the condition that the confirmation command is 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.

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

  When the number N of operation reservation balls of the 1st symbol display device 41 is comparatively small, since the variable display time of the 2nd symbol is shortened, the number N of operation reservation balls of the 1st symbol display device 41 is reduced. In some cases, the time interval at which the trigger for opening the electric accessory provided in the operating port 33 is shortened. As a result, a state is formed in which the game ball is likely to win the operation port 33 in accordance with the decrease in the number N of the operation reservation balls of the first symbol display device 41, and the game ball is awarded to the operation port 33. Therefore, it is possible to prevent the fluctuation display of the first symbol display device 41 from being interrupted.

  In particular, when the gaming state is a probability variation gaming state and a short-time gaming state, as described above, the variation display time of the second symbol is shortened when the number N of active suspension balls of the first symbol display device 41 decreases. By adopting the configuration, it is possible to prevent the variation display of the first symbol from being interrupted in spite of the probability change gaming state and the short time gaming state. Thereby, the player can enjoy the game without feeling irritated, and thus the interest of the pachinko machine 1 can be enhanced.

  In addition, as described above, it is possible to continue the variable display of the first symbol display device 41 each time without interruption, so that adjustment is made such that the game ball easily passes through the through gate 34 and the like. There is no need to increase the number of times of opening the accessory and not to interrupt the change display of the first symbol. In addition, since the variable display time of the second symbol display device 41 is set to be the shortest only when the number N of the active symbol holding balls of the first symbol display device 41 is relatively small, In spite of the large number, it is possible to prevent the electric accessory from being unnecessarily opened. Thereby, it is possible to prevent the payout of prize balls from being increased unnecessarily, and the loss on the hole side is suppressed.

  Furthermore, in the probability variation gaming state and the short-time gaming state, even when the number N of active suspension balls of the first symbol display device 41 is relatively small, if the gaming ball is not launched, the second symbol The variation display is prohibited from being shortened. With this configuration, for example, the player intentionally stops the launch of the game ball in order to increase the opening operation frequency of the electric accessory for the purpose of increasing the payout prize ball, and seems to have digested the operation suspension of the first symbol display device 41 In such a case, since the variation display of the second symbol is not shortened, it is possible to prevent the player from acquiring more than necessary prize balls.

  Further, since it is determined that whether or not a game ball has been launched based on the detection information of the handle sensor 600 used for driving the firing motor 229, a new sensor is separately added for the determination. There is no need to provide the machine 1, and thus the cost of the pachinko machine 1 can be reduced.

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

  (A) In the above embodiment, the first symbol display device 41 is configured to include a liquid crystal display, but may be configured to include other types of display screens such as CRT, dot matrix, and 7 segments.

Alternatively, a configuration in which only odd numbers are given or only even numbers may be given.

  (E) In the above-described embodiment, the main symbol is an image having only a numeric number. However, the main symbol may be displayed together with an attached symbol such as a character (animal, person, article, etc.). In particular, the distinguishability of the main symbol can be improved by making the attached symbol different for each main symbol.

  (F) In the above embodiment, the pachinko machine 1 that teaches the player the jackpot by the jackpot lottery being performed by the main controller 271 and displaying the lottery result on the first symbol display device 41 will be described. However, the present invention is not limited to this. A display device such as a sub-digital display may be provided separately from the first symbol display device 41, and a jackpot may be taught by the display device, and the first symbol display device 41 may be a pachinko machine that does not directly teach the jackpot. That is, it may be a pachinko machine including the first symbol display device 41 and teaching means for teaching the jackpot. In the case of such a configuration, the first display device may function as a production means for enhancing the interest of the game.

  (G) In the above-described embodiment, the pachinko machine 1 having five effective lines and three symbol rows has been described. However, the present invention is not limited to this, and the effective lines are one line or two lines. A pachinko machine or a pachinko machine composed of one or two symbol rows may be used. That is, the number of effective lines and symbol rows and combinations thereof are arbitrary.

  (H) In the above embodiment, the numerical numbers of the main symbols are used for teaching the jackpot occurrence, but the teaching is not limited to this. For example, considering the so-called lucky number-based business venues that need to exchange prize balls that are paid out from pachinko machines according to the symbol where the jackpot has occurred, Whether it is possible or not may be taught by a numerical number.

  (I) In the above-described embodiment, the pachinko machine 1 having a relatively large game area as compared with the prior art has been described. However, the present invention is not limited thereto, and a game machine such as a pachinko machine having a game area or a window as in the conventional art It can also be applied to. Further, the present invention can also be applied to other types of ball and ball game machines different from the above-described embodiment, such as pachinko machines, other ball machines, and sparrow balls, which have other objects. In addition, it can also be applied to a swivel type gaming machine such as a slot machine, and a ball-type belt type gaming machine that uses a gaming ball such as a pachinko ball as a gaming medium.

  (J) In the above embodiment, a description has been given of a configuration in which two types of symbols “O” and “X” are used for the second symbol (ordinary symbol), and the winning is displayed by these symbols. It is good also as a structure which displays winning by two or more types of symbols, or the combination of those symbols.

  (K) In the above embodiment, the second symbol random number counter C4 is used to win the opening operation of the electric accessory provided incidentally to the operation port 33, and the counter value to be won is determined regardless of the gaming state. Although the configuration having the same value has been described, the present invention is not limited to this, and the configuration may be such that the winning counter value is changed according to the gaming state. For example, in the probability variation gaming state and the short time gaming state, the winning counter value may be increased as compared to the normal gaming state and the jackpot gaming state.
