Description

  The present invention relates to a gaming machine.

  For example, some game machines such as pachinko machines and slot machines are equipped with a symbol display device that displays a plurality of symbols in a variable manner on the display screen. When a special gaming state (a big hit state) advantageous to the player occurs, it is displayed. A symbol that is confirmed and displayed on an active line set in advance on the screen is a combination of specific symbols. Then, with the occurrence of a special gaming state, the big prize opening is opened or a big bonus game is entered.

  In such gaming machines, so-called reach display is performed on the display screen as a stage prior to the specific symbol display when entering the special gaming state. As an example, in the symbol display device in which three symbol sequences are variably displayed as one set and the symbols of each symbol sequence are sequentially stopped, when the symbols of the two symbol sequences are temporarily stopped after the variation starts. Reach is displayed when they become the same symbol on the active line. After reaching the reach display, various reach effects are appropriately performed. When a special gaming state occurs, the final stop symbol (for example, the third stop symbol) is further stopped at the same symbol and the symbol is confirmed and displayed. (For example, Patent Document 1).

  In many of this type of gaming machine, the symbols are variably displayed in a predetermined arrangement on the display screen of the symbol display device, and the player recognizes the arrangement and the symbols vary according to the arrangement. Play as a game. For example, in a gaming machine in which symbols with numbers are variably displayed, the symbols vary so that the numbers are in ascending order or descending order. Similarly, even in the case of symbols with English letters added in addition to numbers, the symbols change so that the English letters are in ascending or descending order. In such a case, if the variation display of the symbols is uniform, the reach display is also uniform. Therefore, there was a problem that improvement of the interest of the game was hindered.

Along with this, the dimension Lb from the lower end of the pachinko machine to the upper end of the upper plate 23 is also reduced, which is about 298 mm in the existing model, for example, about 261 mm in the present pachinko machine 10. Here, by lowering the position of the upper plate 23, the vertical distance from the tip of the nozzle of the ball lending device arranged side by side on the left side of the pachinko machine 10 in the game hall is increased, and there is a concern that the lending of the lending ball may be lost. However, in the present embodiment, the rising portion 22a in which the wall surface of the bulging portion 22 is higher than the other wall surface is formed in the left side portion that is the rental ball discharge portion from the nozzle. Thereby, even if it has the structure which lowered the position of the top plate 23, inconveniences, such as spilling of a rental ball, are eliminated. The height of the raised portion 22a may be any as long as it matches the lowered size of the upper plate 23, and the maximum height is 25 mm in the present embodiment.

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

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

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 part outside the rail unit 50, and through this relay terminal hole 59, a connector for connecting a relay terminal plate installed on the back of the game board 60 is exposed to the front side of the pachinko machine 10.

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

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. It demonstrates as an area | region remove | excluding. That is, since the game area does not include the ball guide 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 the present embodiment, the width of the game area (maximum width in the left-right direction) is 418 mm, and the height of the game area (maximum width in the vertical direction) is 445 mm.

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

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

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

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

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

  Returning to the description of FIG. 3, in the resin base 25, below the window hole 26 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher is attached. Yes. The firing rail 61 is fixedly attached to the resin base 25 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path. As described above, since the curvature of the ball guide passage is reduced by greatly expanding the game area as compared with the conventional game area, a device for stabilizing the launch ball is required. Therefore, in the present embodiment, the launch position of the game ball is lowered so that the inclination angle (launch angle) of the launch rail 61 is somewhat larger than the existing one (that is, the launch rail 61 is raised), and By forming the launch rail 61 so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area, the launch rail 61 is made longer than the existing one and sufficiently long. The ball guide distance is secured. Thereby, the game ball launched from the game ball launching device can be guided to the ball guide passage in a more stable state. Further, in order to stabilize the launch ball, the metal plate 62 provided with the launch rail 61 is enlarged, and the metal plate 62 is screwed at a number of locations (15 to 20 in this embodiment). Thus, the launch rail 61 is firmly positioned with respect to the game board 30.

  There is a predetermined gap between the firing rail 61 and the ball guide passage, and a foul ball passage 76 is provided below the gap. Therefore, if the game ball launched from the game ball launching device does not reach the return ball prevention member 54 and returns as a foul ball in the ball guide passage, the foul ball passes through the foul ball passage 76 to the lower plate 16. To be discharged. Incidentally, in the case of the present embodiment, the length of the 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 also a rampage in the ball guide path that jumps to the inner rail portion 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 76. Thereby, all of the foul balls are reliably guided to the foul ball passage 76, and interference between the foul balls and the game balls to be fired next is suppressed.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front door frame 13 side (ball outlet leading from the most downstream portion of the upper plate 23). At this time, since the launch position of the game ball is lowered in this embodiment, the drop from the exit of the ball on the front door frame 13 side to the launch position becomes large, Guide members 63 and 64 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front door frame 13 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device is provided with a ball striking rod that is supported so as to be rotatable about the base end portion, and a game ball is launched along with the rotation of the ball striking ball. It is rare. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to a light metal such as aluminum and reducing the size of the hitting shaft, the head portion of the hitting ball (opposite to the base end) is required to ensure sufficient firing force A weight is provided at the tip of the side. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, the hitting ball can be easily picked or caught, and the effect of facilitating adjustment of the hitting strength of the hitting tip can be obtained.

  A pair of left and right discharge ports 66, 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66, 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distributing unit 245 (see FIG. 13) provided on the back surface of the main body frame 12, and game balls are basically discharged from the first discharge port 66. When the passage leading to the upper plate 23 including the first outlet 66 is filled with game balls, the game balls are discharged from the second outlet 67 instead of the first outlet 66.

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

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

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

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. The small window 79 is provided in the position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, 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 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is closed with respect to the main body frame 12, the pin is pushed in and the front door frame 13 is closed. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 8) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached for conducting the metal fittings to the main body frame 12 side and grounding them. Accordingly, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

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

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

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

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 8 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape close to a circle, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape. Above the window part 101 of the front door frame 13, the frame width of the narrowest part is about 61 mm. The frame width dimension in the present embodiment is substantially the same as the distance between the uppermost portion of the outer rail portion 52 (the upper end of the game area) and the upper end of the main body frame 12 in the main body frame 12, and is 85 mm to It is significantly shorter than the conventional model having the frame width of about 95 mm. Thereby, the visibility of the upper area in the game area can be easily ensured, and the large variable display unit 35 can also be arranged relatively upward. The dimension of the frame width (narrowest part) above the window 101 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be secured, the thickness may be 50 mm or less.

  The left and right frame portions of the front door frame 13 are restricted in reducing the frame width, and need a width dimension sufficient to ensure the strength of the front door frame 13 itself and the glass support strength. In the present embodiment, the narrowest part of the left and right frame parts has a frame width of about 44 mm. In this case, since the game area is greatly expanded in the pachinko machine 10, the frame width of the front door frame 13 is about 44 mm as described above on the left side when viewed from the front of the pachinko machine 10, that is, on the opening / closing axis side. On the other hand, the distance between the left end position of the outer rail portion 52 of the rail unit 50 and the left end position of the main body frame 12 is about 21 mm, and the latter dimension is considerably small. That is, in this configuration, in a state where the front door frame 13 is closed, a part of the ball guide passage overlaps and is covered with the left frame portion of the front door frame 13. However, even if it becomes difficult to visually recognize the game ball in the ball guide passage, the ball guide passage is only a passing area until the game ball is guided to the game area, and the game where the player mainly enjoys the game. The game ball is not difficult to view in the area. Therefore, there is no trouble in actual game. As described above, it is possible to expand the game area without causing any trouble to the game, while ensuring sufficient strength and glass support strength of the front door frame 13.

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

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

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

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 8, reinforcing plates 131, 132, 133, and 134 are respectively attached to the back side of the front door frame 13 and on the left and right and upper and lower outer sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thereby, the closed loop of the electric path by the reinforcing plates 131 to 134 is cut, and the generation of a magnetic field causing noise is prevented.

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

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

  A resin case 136 is attached to the lower reinforcing plate 134 at a position facing the firing rail 61. The resin case 136 accommodates a circuit board for the ball rental operation unit 120. The back surface of the resin case 136 (the surface visible in FIG. 8) is flat, and constitutes the side wall of the firing rail 61 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 61.

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

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

  As described above, the pachinko machine 10 according to the present embodiment is designed to expand the game area. Therefore, when the front door frame 13 is closed, the ball guide formed between the inner and outer rail portions 51 and 52 is used. A part of the passage is covered by the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In this case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of being caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers the section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 8 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137. A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

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

  Next, the configuration of the back surface of the pachinko machine 10 will be described. FIG. 9 is a rear view of the pachinko machine 10, and FIG.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described.

In the present embodiment, the various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. A device 312 (launch control board) and a power supply device 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units, and are provided with a support shaft part in a part to provide the main body frame 12. Or it has the composition which can be developed to the back of game board 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 11, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged below it. Yes. Further, the back pack unit 203 is disposed in a region partially overlapping with the first control board unit 201.

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

  The support shafts M1, M4, and M6 that rotatably support the units 201 to 203 have a hinge structure that can be easily removed while the units 201 to 203 are opened from the back surface of the pachinko machine 10. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3, rotating the unit 201 around the axis A, and expanding the unit 201. Lift in condition. Thereby, if there is no back pack unit 203, the first control board unit 201 can be removed.

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

Note that a synthetic resin speaker box 246 is attached to the lower end portion of the main body frame 12 to surround the back of the speaker 20 installed on the back side of the back wall panel 17. The sound quality of the low range is improved by functioning so as not to miss.

  Next, the configuration of the first control board unit 201 will be described with reference to FIGS. 16 is a front view of the first control board unit 201, FIG. 17 is a perspective view of the unit 201, FIG. 18 is an exploded perspective view of the unit 201, and FIG. 19 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251. The main control device 271 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port for communicating with various devices, and a random number used in various lotteries. A main substrate including a generator, a clock pulse generation circuit used for time counting and synchronization, etc. is provided, and the main substrate is accommodated in a substrate box 273 as an encapsulating means made of a transparent resin material or the like. Configured. The substrate box 273 includes a substantially rectangular parallelepiped box base and a box cover that covers the 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 unsealed, any configuration can be applied. Here, as shown in FIG. 17 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 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 other ROM, RAM, various ports, and the like.

Yes. That is, power is supplied to the display control device 214 and the sound lamp control device 272 independently of each other.

  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 length and breadth, and are formed with steps 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. The main control device 271 is disposed on the horizontally long substrate mounting surface 252 and the sound 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 172 is fixed to the board mounting surface 253 with screws or the like at a plurality of locations.

  Here, as shown in FIGS. 18 and 19, the substrate mounting surface 252 is formed with horizontally elongated through holes 256 at two positions on the left and right. On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally operable fixtures 277 at two places on the left and right sides of the back surface thereof. When the main controller 271 is mounted on the board mounting surface 252, the main control board 271 is placed so that the fixing tool 277 is inserted into the through hole 256 of the board mounting surface 252, and the fixing tool 277 is placed in this state. The main control device 271 is locked by the turning operation. 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 10, 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.

  As shown in (a) to (k) of FIG. 28, the first symbol is composed of 10 types of main symbols each having numbers “0” to “9” and one type of petal-shaped symbols. It consists of sub-designs. Specifically, in each main symbol, numbers “0” to “9” are attached on the rear symbol consisting of a wooden box, of which the odd symbols (1, 3, 5, 7, 9) Each numerical number is assigned to the front side of the wooden box. On the other hand, in the main symbols of even numbers (0, 2, 4, 6, 8), each side of the attached symbol such as amulet, furoshiki, helmet, bag, kettle drawn almost full front side of the wooden box. Numeric numbers are relatively small. In this case, the main symbol to which the odd number (1, 3, 5, 7, 9) is attached corresponds to the “high probability symbol”, and when the high probability symbol is aligned, the big game state that is a special gaming state is entered, After that, it shifts to a high probability state. In addition, the main symbol with an even number (0, 2, 4, 6, 8) corresponds to a “low probability symbol”, and when the low probability symbol is aligned, it shifts to a jackpot state. It does not transition to a high probability state. The high probability state means a state in which the combination of the first symbol is 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, and a normal state (low (Probability state) refers to a time when such a probability variation state is not present.

  The player plays a game with the expectation that the first symbol is aligned with a high probability symbol, that is, the number attached to the main symbol when the fluctuation of the first symbol is stopped is a high probability number (odd number). In the high-probability symbol, the numerical symbol is drawn large and it is emphasized that the probability is high. Therefore, the interest of the game is enhanced.

  Next, the display screen G of the first symbol display device 41 will be described. As shown in FIG. 29 (a), the display screen G of the first symbol display device 41 is roughly divided into two vertically, and the lower 2/3 is the main display region Rm in which the first symbol is variably displayed. (Upper 1/3) is a sub display area Rs for displaying a notice effect and a character. The main display area Rm corresponds to the “first display area”, and the sub display area Rs corresponds to the “second display area”.

  In the main display area Rm, three symbol rows Z1, Z2, and Z3 of left, middle, and right are set, and the above-described first symbols are displayed in a prescribed order in each of the symbol rows Z1 to Z3. That is, in each of the symbol rows Z1 to Z3, the main symbols are arranged in ascending or descending numerical order, and one sub symbol is arranged between the main symbols. At this time, a total of 20 first symbols including 10 main symbols and 10 sub symbols are set in each of the symbol rows Z1 to Z3. In the main display region Rm, 20 first symbols are variably displayed in each symbol row Z1 to Z3 so as to scroll from top to bottom with periodicity. In particular, the numbers of main symbols appear in descending order in the left symbol row Z1, and the numbers of main symbols appear in ascending order in the middle symbol row Z2 and the right symbol row Z3. In the main display area Rm, the first symbols are displayed in the upper, middle, and lower three rows for each of the symbol rows Z1 to Z3, and as a result, a total of nine first symbols in three rows and three columns are displayed. It has come to be.

  In the main display area Rm, 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. In each game, the variable display of the first symbol is stopped in the order of the left symbol column Z1 → the right symbol column Z3 → the middle symbol column Z2, and when the symbol is confirmed, the first symbol is a big hit on any active line. If a combination of symbols (in this embodiment, the same combination of main symbols) is arranged, a jackpot moving image is displayed as a jackpot.

  The sub display area Rs is horizontally long above the main display area Rm, and is further equally divided into three areas. In this case, of the three areas of the sub display area Rs, the right area is the first notice area Rs1, the left area is the second notice area Rs2, and the center area is the third notice area Rs3. The first notice area Rs1 and the second notice area Rs2 are areas that overlap the right door 171 and the left door 172 (see FIG. 5) described above. The first notice area Rs1 is hidden by the right door 171 and the second notice area Rs2 is hidden by the left door 172. On the other hand, the third notice area Rs3 does not overlap the right door 171 and the left door 172, and is a display area that can always be viewed by the player.

  On the actual display screen, as shown in FIG. 29 (b), a total of nine main symbols and sub-designs of the first symbol are displayed in the main display area Rm. The figure shows an arbitrary display state. Further, in the sub display area Rs, when the right door 171 and the left door 172 are disposed, the first notice area Rs1 and the second notice area Rs2 are hidden, and the display contents cannot be visually recognized. When the right door 171 is opened, the first notice area Rs1 appears, and a predetermined notice effect is performed in the first notice area Rs1. In addition, the second notice area Rs2 appears by opening the left door 172, and a predetermined notice effect is performed in the second notice area Rs2. In the third notice area Rs3, a display is normally performed so that a predetermined character (a boy character with a bee stick in the figure) performs a predetermined operation. And the notice effect by the said character etc. is performed as needed.

  As described above, the display screen G of the first symbol display device 41 is divided into the main display region Rm and the sub display region Rs in principle, but straddles the display regions Rm and Rs, or A display effect can also be performed by integrating at least part of the main display area Rm and the sub display area Rs. For example, after the predetermined reach occurs, the display area Rm and Rs are combined into one display area without the area division of the main display area Rm and the sub display area Rs, and display effects using the display area are achieved. Done. However, the display form after the occurrence of reach will be described in detail later.

  Incidentally, in the present embodiment, the right door 171 and the left door 172 cannot be seen through the back, but for example, the right door 171 and the left door 172 are made of a translucent material, and the right door 171 and the left door 172 The image behind the door 172 may be blurred or slightly transparent. In this case, display effects are performed in the first notice area Rs1 and the second notice area Rs2 even in a state where the right door 171 and the left door 172 are hidden. Then, even if the first notice area Rs1 and the second notice area Rs2 are concealed by the right door 171 and the left door 172, the player can expect the expectation to shift to the big hit state because the effects behind them can be slightly seen through. Can be given to

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

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information during the game to perform jackpot lottery, setting the symbol display of the first symbol display device 41, and the like. Specifically, As shown in FIG. 30, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 41, and the first symbol display device 41 are fluctuated and fluctuated. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the operation port 33 is provided. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in time series in accordance with the winning history.

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

  The jackpot symbol counter C2 determines the symbol at the time of fluctuation stop of the first symbol display device 41 in the case of a jackpot, and in the present embodiment, the first symbol display device 41 has five effective lines, Since ten specific symbols (main symbols) are set, 50 counter values (0 to 49) are prepared. That is, the jackpot symbol counter C2 is configured to increment one by one within the range of 0 to 49 and return to 0 after reaching the maximum value (ie 49). 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 only one before and after the reach symbol, and the last stop symbol after the reach has 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 the reach other than the front and rear deviation, and C3 = 22 to 238 corresponds to the complete deviation. 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 in the 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 by 1 in order 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 finer symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, 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 the combination of 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 first symbol display device 41 starts the variation of the first symbol.

  The left, middle and right off symbol counters CL, CM, and CR determine the stop symbol of the left row 1st symbol, the middle row 1st symbol, and the right row 1st 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 upper, middle and lower symbols are determined.

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

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second symbol random number counter C4 is used for the lottery of the second symbol display device 42. The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

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

  FIG. 36 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.

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

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

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. The start winning process will be described with reference to the flowchart of FIG. 37. In step S701, whether or not the game ball has won the start opening 33 (start winning) is determined based on the detection information of the operation opening switch 224. If it is determined that the game ball has won the operation port 33, in the subsequent step S702, it is determined whether or not the number N of operation reservation balls of the first symbol display device 41 is less than the upper limit value (4 in the present embodiment). Determine. The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In the subsequent step S704, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in the step S603 are stored in the first free area of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

  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 S704). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses). .

  FIG. 38 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 38 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, in step S801, the used register is saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the power-off occurrence information is set in the backup area 503a, and in step S804, a power-off notification command indicating that the power has been cut off is transmitted to another control device. In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. 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 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 38 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 31 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 with a reset at power-on.

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

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

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

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

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

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

  Next, in step S202, the variation type counters CS1 and CS2 are updated. 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 this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503. In subsequent step S203, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  The update process of each outlier symbol counter CL, CM, CR will be described. As shown in FIG. 33, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. It is determined whether or not it is time to update the symbol counter CM symbol symbol CM. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. On the other hand, if it is time to update the middle symbol sequence (YES in step S302), the process proceeds to step S304 to update the out-of-middle symbol counter CM. Furthermore, if the update timing of the right symbol sequence (both steps S301 and S302 are NO), the process proceeds to step S305, where the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The calculation result is out of order and is used as the current value of the symbol counters CL, CM, CR. According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, the set counter symbols CL, CM, and CR are updated for one set.

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

  After the update of the off symbol counters CL, CM, and CR, in step S204 in FIG. 32, the prize ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed. By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

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

  In step S207, display control of the second symbol (for example, a normal symbol of “◯” or “x”) by the second symbol display device 42 is executed. Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second symbol random number counter C4 is acquired and the second symbol is displayed on the display unit 45 of the second symbol display device 42. Is displayed. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the operating port 33 is released for a predetermined time. Although the description is omitted, the second symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 36, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3.

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

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

  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, in step S401, it is determined whether or not a big hit is currently being made. 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. In a succeeding step S402, it is determined whether or not the first symbol display device 41 is displaying the variation of the first symbol. Then, if it is not a big hit and is not displaying the variation of the first symbol, the process proceeds to step S403, and it is determined whether or not the number N of active suspension balls of the first symbol display device 41 is greater than zero. Then, when the jackpot is being hit or the number N of operation-reserved balls is 0, the present process is terminated as it is.

  If neither the big hit or the change in the first symbol is being displayed and if the number N of activated balls is> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of active suspension balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, the first symbol variation start process is executed. Here, the details of the variation start process will be described with reference to the flowchart of FIG. 35. In step S501, it is determined whether or not it is a big hit based on the value of the big hit random number counter C1 stored in the execution area of the reserved ball storage area. To do. Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. “601, 661” is the winning value.

  If it is determined that the game is a jackpot, in step S502, a table corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (value of the jackpot symbol counter C2). And a symbol representing the correspondence between the symbol and the symbol), and the symbol is set as a stop symbol command. At this time, the numbers 0 to 49 of the jackpot 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 gathered with a predetermined specific symbol, the state changes to a probability variation state. However, when the symbols are not specific symbols (non-specific symbols), the probability variation state is not entered.

  Next, in step S503, the variation pattern of the first symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach type such as normal reach, super reach, premium reach, and other rough types are determined based on the value of the first variation type counter CS1. And the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) More detailed pattern variation modes are determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set or to set 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 the game is not a big hit, it is determined in step S504 whether or not reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area. In the case of the above, in step S505, it is determined whether the reach is out of front or back based on the value of the reach random number counter C3. In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 238, of which “0, 1” corresponds to the out-of-front reach and “2-21” corresponds to the reach other than the back-and-forth out- “22 to 238” corresponds to no reach (complete detachment).

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

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

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

  Returning to the description of FIG. 34, if step S402 is YES, that is, if the variation of the first symbol is being displayed, the process proceeds to step S407 to determine whether or not the variation time has elapsed. 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. In step S408, a confirmation command set for confirming the stop symbol is set, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 39 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

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

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

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

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

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

  In FIG. 40, in step S1001, a command from the main controller 271 is acquired, and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

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

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

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

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

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

  Here, in the prize ball control process shown in FIG. 41, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, where the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

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

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

  42, in step S1201, the payout motor 358a is driven to execute payout of the ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

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

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

  Next, a specific procedure of display control by the display control device 214 will be outlined. FIG. 43 is a flowchart showing display control processing executed by the CPU 521 in the display control device 214. The CPU 521 executes display control of the first symbol display device 41 while processing various commands provided from the main control device 271 according to the procedure shown in FIG.

  In FIG. 43, first, in step S1301, it is determined whether a display command has been received from the main controller 271 or not. When step S1301 is NO, it waits until it receives some command. When the display command is received, the process proceeds to step S1302, and the contents of the display command are stored in the work RAM 523. In step S1303, 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. The internal command is a command for designating a series of display effects from the start to the end of variable display, and a necessary internal command is generated each time based on information stored in the work RAM 523. As a result, the VDP 524 performs a drawing process in response to a command (internal command) from the CPU 521, and starts the variable display of symbols on the first symbol display device 41. At this time, the CPU 521 outputs a control command for driving voices and lamps and a control command for operating the right door 171 and the left door 172 while synchronizing with the display effects at each time. Send to. As a result, the sound lamp control device 272 drives the right door 171 and the left door 172 in addition to the sounds and lamps in accordance with the control command from the CPU 521. It should be noted that the symbol variation display is continued under the cooperation of the CPU 521 and the VDP 524 until the display command is received once until the confirmation command is received thereafter. Meanwhile, the CPU 521 performs the control of the VDP 524 and the command reception process shown in FIG. 43 in parallel. The control in the sound lamp control device 272 is the same.

  Thereafter, in step S1304, it is determined whether or not a confirmation command has been received from main controller 271. Then, the process proceeds to step S1305 on the condition that the confirmation command has been received, and instructs the VDP 524 to confirm the display with the stop symbol. As a result, the VDP 524 confirms and displays the changed symbol as a stop symbol. In this way, a series of display processes from the start of pattern change to the stop of change (determined display) are performed. 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.

  Here, an outline of an internal command generated by the display control device 214 will be described with reference to FIG. FIG. 44 is a schematic diagram showing the basic structure of internal commands stored in the program ROM 522. As shown in FIG. When the CPU 521 of the display control device 214 receives a display command (variation pattern command) from the main control device 271, the CPU 521 determines an internal command according to the display command and sequentially outputs variation control data included in the internal command.

  In FIG. 44, the fluctuation control data of the internal command is roughly divided into a normal fluctuation data group D1, a normal reach data group D2, and a super reach data group D3. Then, each data of the normal reach data group D2 is sequentially output when a normal reach occurs, and each data of the super reach data group D3 is sequentially output when a super reach occurs. Specifically, during normal variation of a symbol, normal variation background display data, character display data, normal variation sound effect data, normal variation LED data, normal variation data 1, 2,... N are sequentially output at a specified timing. . When normal reach occurs, normal reach background display data, normal reach sound effect data, normal reach LED data, normal reach data 1, 2,... N are sequentially output at a prescribed timing. When super reach occurs, super reach background display data, super reach sound effect data, super reach LED data, accessory data, super reach data 1 and 2, notice selection data, super reach data 3,. Are output sequentially. The output of each data is continued until end data is output. The notice selection data is output based on a lottery result based on a notice random number.

  In such a case, background display data, character display data, normal variation data, reach data, and notice selection data are output to the VDP 524, and based on the background display data, character display data, and notice selection data, the corresponding background each time. , Characters and notice symbols are displayed on the display screen. Further, based on the normal fluctuation data and each reach data, the corresponding fluctuation pattern is displayed on the display screen in accordance with a prescribed time rule (fluctuation speed, time, etc.). In addition, sound effect data, LED data, and accessory data are output to the sound lamp control device 272, and based on each data, auxiliary effects by sounds, lamps (LED), right door 171 and left door 172 are provided. As appropriate.

  Next, in the display control by the display control device 214, a specific example will be given of what display is actually performed when reach occurs and how the right door 171 and the left door 172 operate on the display screen. explain. 45 to 50 show display examples showing the display screens of the first symbol display device 41 in various reach patterns. Here, six types of reach patterns from pattern 1 to pattern 6 are illustrated. Of these, pattern 1 is a reach pattern called normal reach, and patterns 2 to pattern 6 are reach patterns called super reach. is there.

  In the pattern 1 shown in FIG. 45, both the right door 171 and the left door 172 remain closed, and the main display area Rm and the sub display area Rs remain divided into two areas. In this case, the background screen in the main display area Rm is not changed from that in the normal state, and the variable display of the final stop symbol (the symbol in the middle symbol row) is performed in substantially the same manner as in the normal state.

  In the pattern 2 shown in FIG. 46, the right door 171 and the left door 172 are both closed, but the main display area Rm and the sub display area Rs are removed, and the center of the main display area Rm and the sub display area Rs is removed. A reach effect is performed using the area (the third notice area Rs3 described with reference to FIG. 29). In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a girl character with petals in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. The final stop pattern fluctuates while repeating expansion and contraction.

  In pattern 3 shown in FIG. 47, the right door 171 is opened and the left door 172 is closed. In addition, the main display area Rm and the sub display area Rs are separated from each other, and the right area and the center area of the main display area Rm and the sub display area Rs (first and third notice areas Rs1, Rs3 described in FIG. 29). And reach production. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character riding a crane truck in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. The final stop symbol changes while being lifted by a crane.

  In the pattern 4 shown in FIG. 48, the right door 171 is closed and the left door 172 is opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and the left area and the center area of the main display area Rm and the sub display area Rs (second and third notice areas Rs2 and Rs3 described in FIG. 29). And reach production. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character who operates the conveyor in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) appears in that display state. Is displayed. The final stop symbol fluctuates while being moved in the horizontal direction on the conveyor in the left side region and the central region (second and third notice regions Rs2 and Rs3 described in FIG. 29) of the original sub display region Rs.

In the pattern 5 shown in FIG. 49, the right door 171 and the left door 172 are both opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and a reach effect is performed using the main display area Rm and the entire sub display area Rs. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character with a mallet and a girl character staring at it) appears, and the final stop pattern is displayed in that state. The change display of (the symbol in the middle symbol row) is performed. The final stop symbol moves from top to bottom and fluctuates while being beaten one by one with a mallet.

Finally, in the pattern 6 shown in FIG. 50, the right door 171 and the left door 172 are both opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and a reach effect is performed using the main display area Rm and the entire sub display area Rs. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character with a wooden mallet in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. In particular, in the pattern 6, the number of effective lines is increased from the normal five lines, and the degree of expectation for shifting to the big hit state is increased. The final stop symbol moves from top to bottom and fluctuates while being beaten one by one with a mallet.

  Next, the super reach of each of the patterns 2 to 6 will be described in more detail while showing the change of the symbols in time series. In the following description, for the sake of convenience, the above-described main symbols are described by numerical numbers assigned to them. Specifically, “0” symbol, “1” symbol, “2” symbol,. 9 ”Describe as a symbol. When the main symbols once stopped in the left and right symbol rows Z1 and Z3 are the same, a line connecting the left symbol and the right symbol is described as a reach line. If necessary, the display screen G, the main display area Rm, the sub display area Rs, the symbol columns Z1 to Z3, the first notice area Rs1, the second notice area Rs2, and the third notice area Rs3 described in FIG. And other terms will be used.

  The reach pattern of pattern 2 shown in FIG. 46 will be described in detail based on a series of display modes shown in FIGS.

  First, in (a), in the main display region Rm of the display screen G, after the symbols of the symbol rows Z1 to Z3 have normally changed, the change display of the left symbol and the right symbol is temporarily stopped, and the reach on the reach lines La1 and La2 is reached. Occurs. In the reach line La1, the left and right symbols are “1” symbols, and in the reach line La2, the left and right symbols are “0” symbols. These reach lines La1 and La2 correspond to the right rising line L4 and the left rising line L5 described with reference to FIG. Both the right door 171 and the left door 172 remain closed, and the main display area Rm and the sub display area Rs remain divided into two areas. When the reach display occurs, the boy character displayed in the center area of the sub display area Rs (the third notice area Rs3 described with reference to FIG. 29) notifies that the reach has occurred. At this stage, the background screen in the main display area Rm is not changed from that in the normal state, and the change display of the middle symbol is performed in the same manner as the normal change.

Thereafter, as shown in (b), the area division of the main display area Rm and the sub display area Rs is removed, and a predetermined reach effect is performed using the main display area Rm and the central area of the sub display area Rs. That is, the main display area Rm is expanded so as to integrate the central area of the sub display area Rs. In this case, the background screen is changed to a different one from the normal time, and the girl character with the petals in the background is displayed. Further, as shown in (b) and (c), the middle symbol, which is the final stop symbol, is variably displayed in ascending order while repeating expansion and contraction at the position where the reach line La1 and the reach line La2 intersect. Then, as shown in (d), when the final stop symbol stops at the “0” or “1” symbol and is displayed in a fixed manner, the girl character is notified that a big hit has occurred. If the final stop symbol does not stop at the winning symbol (in this example, “0” or “1” symbol) even if the super-reach is developed as described above, the girl character does not win the jackpot. The occurrence is notified.

  Next, the reach pattern of pattern 3 shown in FIG. 47 will be described in detail based on a series of display modes shown in FIGS.

  In (a), in the main display area Rm of the display screen G, after the symbols of the symbol rows Z1 to Z3 have normally changed, the left and right symbols change display is temporarily stopped, and reach occurs on the reach line Lb1. . In the reach line Lb1, the left and right symbols are “4” symbols, and the reach line Lb1 corresponds to the lower line L3 described in FIG. When the reach display occurs, the boy displayed in the center area of the sub display area Rs (the third notice area Rs3 described with reference to FIG. 29) notifies that the reach has occurred.

  Here, when the reach display is performed on the horizontal line as shown in the figure, in the left and right symbol rows Z1 and Z3, the symbol “4” is the symbol for reach display, but the other symbols are not the targets for reach display. . Therefore, when reach occurs, translucent processing is applied to symbols that are not subject to Lee (in the figure, “3” symbols other than “4” symbols, “5” symbols, and sub-patterns with petal shape). Is being processed). As a result, the symbols other than the reach display are displayed in a light color and blurred, whereas the reach display symbols are highlighted. In addition, although explanation is omitted, in the case of FIG. 51, when the reach display is performed with the cross line as shown in (a), the symbols that are unrelated to the reach display (in this case, the sub-design) are still translucent. Processing has been applied. The same applies to other reach described later.

  Thereafter, as shown in (b), the boy character strikes the right door 171 with a mallet. At this time, the right door 171 operates as if it is opened by being hit with a wooden mallet, and a crane vehicle is displayed in the right area of the sub display area Rs (the first notice area Rs1 described in FIG. 29). Is done. At the stage of (a) and (b), the background screen of the main display area Rm is not changed from that in the normal state, and the change display of the middle symbols is performed in substantially the same manner as the normal change. Further, the main display area Rm and the sub display area Rs remain divided into two areas.

  Thereafter, in (c), the area division of the main display area Rm and the sub display area Rs is removed, and a predetermined reach effect is performed using the main display area Rm and the center area and the right area of the sub display area Rs. That is, the main display area Rm is expanded so as to integrate the central area and the right area of the sub display area Rs. In this case, the background screen is changed to a different one from that in the normal time, and the boy character displayed in the central area of the sub display area Rs is displayed to operate the crane vehicle. In addition, the middle symbol, which is the final stop symbol, is variably displayed when a wooden box with different main symbols on each side is lifted by a crane truck and rotated, or thrown forward and rolled around the crane truck. The Then, as shown in (d), when the final stop symbol stops at the symbol “4” and is displayed in a fixed manner, the boy character riding on the crane vehicle notifies that a big hit has occurred. If the final stop symbol does not stop at the winning symbol (in this example, “4” symbol) even if the super-reach is developed as described above, the boy character does not generate a big hit. Informed.

  Next, the reach pattern of the pattern 4 shown in FIG. 48 will be described in detail based on a series of display modes of FIGS. 53 (a) to 53 (d).

  In (a), in the main display area Rm of the display screen G, after the symbols of the symbol rows Z1 to Z3 normally change, the change display of the left symbol and the right symbol is temporarily stopped, and reach occurs on the reach line Lc1. . In the reach line Lc1, the left and right symbols are “9” symbols, and the reach line Lc1 corresponds to the upper line L1 described in FIG. At this time, the left and right symbols that have not reached reach display (in this example, “0” and “8” symbols are translucently processed. When reach display occurs, the central region of the sub-display region Rs) The boy character displayed in (third notice area Rs3 described with reference to FIG. 29) notifies that a reach has occurred.

  Thereafter, as shown in (b), the boy character performs an effect of hitting the left door 172 with a mallet. At this time, the left door 172 operates as if it is opened by being struck by a wooden mallet, and a conveyor is displayed in the left area of the sub display area Rs (second notice area Rs2 described in FIG. 29). The At the stage of (a) and (b), the background screen of the main display area Rm is not changed from that in the normal state, and the change display of the middle symbols is performed in substantially the same manner as the normal change. Further, the main display area Rm and the sub display area Rs remain divided into two areas.

  Thereafter, in (c), the area division of the main display area Rm and the sub display area Rs is removed, and a predetermined reach effect is performed using the main display area Rm and the center area and the left area of the sub display area Rs. That is, the main display area Rm is expanded so as to integrate the central area and the left area of the sub display area Rs. In this case, the background screen is changed to a different one from that in the normal time, and the boy character displayed in the central area of the sub display area Rs is displayed to operate the conveyor. In addition, in the middle symbol as the final stop symbol, the variable display position changes from the central portion of the main display region Rm to the region that combines the central region of the sub display region Rs and the left region, and rides on the conveyor in the horizontal direction. Fluctuation is displayed while moving at a low speed or moving at a high speed. Then, as shown in (d), when the final stop symbol stops at the “9” symbol and is displayed in a fixed manner, the boy character operating the conveyor notifies that a big hit has occurred. If the final stop symbol does not stop at the winning symbol (in this example, “9” symbol) even if the super-reach is developed as described above, the boy character does not generate a big hit. Informed.

  Next, the reach pattern of the pattern 5 shown in FIG. 49 will be described in detail based on a series of display modes shown in FIGS.

  In FIG. 54 (a), in the main display area Rm of the display screen G, after the symbols in the symbol rows Z1 to Z3 have normally changed, the left and right symbols change display is temporarily stopped, but the left on each effective line. The design and the right design are different designs. That is, at this stage, no reach line is generated on the effective lines L1 to L5. Therefore, in the central area of the secondary display area Rs (the third notice area Rs3 described with reference to FIG. 29), a display is performed as if the game character would not be a big hit by the boy character. However, immediately after that, as shown in (b), the boy character squeezes both fists and a flame is displayed behind the boy character and the middle symbol.

  Then, in (c), the left and right doors 171 and 172 are opened as if blown away by the hot air of the flame that burns behind the boy character. By opening the left and right doors 171 and 172, the right and left regions (first and second notice regions Rs1 and Rs2 described in FIG. 29) of the sub display region Rs are hidden behind the doors 171 and 172. The main symbol appears. At this time, in the right region and the left region of the sub display region Rs, the main symbols in accordance with the periodicity of the left symbol and the right symbol are displayed. A symbol “6” appears above the symbol “7”, and a symbol “7” appears above the symbol “6” in the right symbol column Z3 arranged in ascending order. As a result, the reach line Ld1 is generated in the left and right “7” symbols, and the reach line Ld2 is generated in the left and right “6” symbols. In the stages (a) to (c), the background screen of the main display area Rm is not changed from that in the normal state, and the middle symbols are displayed in the same manner as in the normal state. Further, the main display area Rm and the sub display area Rs remain divided into two areas.

  Thereafter, in (d), the main display area Rm and the sub display area Rs are separated from each other, and a predetermined reach effect is performed using the main display area Rm and the sub display area Rs. That is, the main display area Rm is expanded so as to integrate the entire sub display area Rs. In this case, the background screen is changed to a different one from that in the normal time, and the figure of the boy character displayed in the central area of the sub display area Rs has a mallet and the girl character staring at it. Further, the reach display is slid downward while the reach display on the reach lines Ld1 and Ld2 is maintained. As a result, the reach lines Ld1 and Ld2 are moved and displayed in the area that should be originally displayed, that is, the main display area Rm. In other words, the reach lines Ld1 and Ld2 on the ineffective line are moved onto the predetermined effective line. The display form is FIG. 55A, and the reach lines Ld1 and Ld2 in this state correspond to the right-up line L4 and the left-up line L5 described in FIG. As the reach lines Ld1 and Ld2 slide, the left and right symbols (in this example, “8” symbol and “5” symbol) other than the reach line are deleted from the display screen G.

Thereafter, as shown in FIGS. 55 (b) and 55 (c), the middle symbol as the final stop symbol moves from the top to the bottom in the center of the display screen G, and the boy character is beaten one by one with a mallet. It is displayed in a variable manner so as to jump out forward. Then, as shown in (d), when the final stop symbol stops at the symbol “6” or “7” and is confirmed and displayed, the boy character is notified that a big hit has occurred. Even if the super-reach is developed as described above, if the final stop symbol does not stop at the winning symbol (in this example, “6”, “7” symbol), the boy character does not win the jackpot. The occurrence is notified.

  Next, the reach pattern of the pattern 6 shown in FIG. 50 will be described in detail based on a series of display modes of FIGS. 56 (a) to 56 (d) and FIGS. 57 (a) to 57 (c). In this pattern 6, as a difference from each of the above reach patterns, an effective line is added on the display screen G, and a display area including not only the main display area Rm but also the sub display area Rs, That is, the effective line is set using the entire display screen G.

  Specifically, as shown in FIG. 58 (a), the left and right doors 171 and 172 are closed, and the main display area Rm of the display screen G has three upper and lower stages in the left and right symbol rows Z1 and Z3. One symbol is displayed, and a total of five effective lines are set by these first symbols. This display form is as already described. On the other hand, as shown in FIG. 58B, the entire display screen G including the main display region Rm and the sub-display region Rs with the left and right doors 171 and 172 opened has a left and right symbol row Z1. , Z3, the first symbol of the upper and lower five stages is displayed. In such a case, the first line displayed in the sub-display area Rs is also set as the target symbol for reach display, thereby increasing the effective line. In the present embodiment, effective lines L11, L12, and L13 are newly provided.

  In the pattern 5, the first symbol is displayed using the sub display area Rs and a reach line is generated. However, in the pattern 5, the reach line is slid to the original main display area Rm and the number of effective lines increases. Absent. On the other hand, in the present pattern 6, reach display using the sub display area Rs is allowed by using the display design of the sub display area Rs as it is, thereby increasing the number of effective lines.

  Hereinafter, the display mode of the pattern 6 will be described. First, in FIG. 56A, in the main display region Rm of the display screen G, the left symbol and the right symbol change display after the symbols of the symbol rows Z1 to Z3 normally change. Temporarily stops and cross line reach occurs on the reach lines Le1 and Le2. At this time, in the reach line Le1, the left and right symbols are “7” symbols, and in the reach line Le2, the left and right symbols are “6” symbols. These reach lines Le1 and Le2 correspond to the right rising line L4 and the left rising line L5 described in FIG. At this stage, both the right door 171 and the left door 172 remain closed. When the reach display occurs, the boy character displayed in the center area of the sub display area Rs (the third notice area Rs3 described with reference to FIG. 29) notifies that the reach has occurred.

  Thereafter, as shown in (b) and (c), the boy character performs an effect of hitting the lower part of the sub display area Rs with a mallet, and both left and right vibrations are propagated as if the vibrations when hit with the mallet were propagated. Doors 171 and 172 are opened. By opening the left and right doors 171 and 172, the right and left regions (first and second notice regions Rs1 and Rs2 described in FIG. 29) of the sub display region Rs are hidden behind the doors 171 and 172. The main symbol appears. At this time, in the right and left areas of the sub display area Rs, symbols that are contrary to the periodicity (predetermined arrangement) of the left symbols and the right symbols are displayed, and the left symbol row Z1 arranged in descending order. Then, a “7” symbol appears above the “6” symbol against the original arrangement order, and even in the right symbol row Z3 arranged in ascending order, a “7” symbol appears above the “7” symbol against the original arrangement order. 6 ”symbol appears. More specifically, a main symbol that is the same as the lower main symbol among the main symbols previously displayed in the main display region Rm newly appears. As a result, apart from the reach lines Le1 and Le2, a reach line Le3 consisting of a “6” symbol and a reach line Le4 consisting of a “7” symbol are generated, and a total of four reach lines are generated simultaneously. The reach lines Le3 and Le4 correspond to the effective lines L12 and L13 described with reference to FIG.

  In the display mode of (c), the symbols in the same symbol sequence (for example, the center “6” symbol and the lower “7” symbol in the left symbol sequence Z1) and the symbols (for example, in the left symbol sequence Z1 in the left symbol sequence Z1). The upper “7” symbol) is displayed in a mixed manner. Further, regarding the “6” symbol at the center of the left symbol row Z1 and the “7” symbol at the center of the right symbol row Z3, both reach lines Will be involved. As a result, it seems that the reach of the cross line overlapped vertically two times. Further, since the symbols of the left and right symbol rows Z1 and Z3 are misplaced, it is as if a reach in a zigzag line has occurred. In the stages (a) to (c), the background screen of the main display area Rm is not changed from that in the normal state, and the middle symbols are displayed in the same manner as in the normal state. Further, the main display area Rm and the sub display area Rs remain divided into two areas.

  Thereafter, as shown in (d), the area division of the main display area Rm and the sub display area Rs is removed, and a predetermined reach effect is performed using the main display area Rm and the sub display area Rs. That is, the main display area Rm is expanded so as to integrate the entire sub display area Rs. In this case, the background screen is changed to a different one from that at the normal time, and the boy character displayed in the center area of the sub display area Rs is displayed with a wooden mallet.

Thereafter, as shown in FIGS. 56 (d) and 57 (a), (b), the middle symbol as the final stop symbol is variably displayed at the center of the display screen G from the top to the bottom. When the medium symbol (“6” symbol or “7” symbol in the figure) that is a big hit approaches the reach line, the middle symbol is beaten with a mallet by the boy character as if the middle symbol is stopped. At this time, the boy character is always located at the approximate center in the vertical direction of the display screen, but when the jackpot symbol approaches the reach line, the visibility of the left and right symbols displayed on the reach line is not hindered. While going back and forth between the right side and the left side on the display screen G, the middle symbol is beaten with a mallet. More specifically, as shown in FIG. 56 (d), when the “6” symbol in the middle symbol row Z2 approaches the reach line Le3, the symbol on the reach line Le3 (in this case, the symbol in the left symbol row Z1). The boy character strikes the “6” symbol from the right side with a mallet so that it does not overlap with the “6” symbol. As shown in FIG. 57 (a), when the “7” symbol in the middle symbol row Z2 approaches the reach line Le4, the symbol on the reach line Le4 (in this case, the “7” symbol in the right symbol row Z3). ) The boy character strikes the “7” symbol with a wooden mallet from the left side.

  Here, when the boy character strikes the middle symbol coming down from above, only the symbol subject to the strike is normally displayed for the middle symbol, and the other symbols are displayed with the semi-transparent processing applied. It has come to be. As for the left and right symbols, only the reach line that is established with the same symbol as the middle symbol to be beaten is normally displayed, and the other symbols are displayed after being translucently processed. More specifically, FIG. 56 (d) shows a case where the “6” symbol, which is the middle symbol, approaches the reach line Le3 in which “6” symbols are arranged on the left and right sides. The “6” symbol on the line Le3 and the “6” symbol, which is the middle symbol, are normally displayed, and the other symbols are subjected to translucency processing. FIG. 57A shows a case in which the “7” symbol, which is the middle symbol, approaches the reach line Le4 in which “7” symbols are arranged on the left and right. The “7” symbol and the “7” symbol, which is the middle symbol, are normally displayed, and the other symbols are subjected to translucency processing. Further, FIG. 57B shows a case where the middle symbol “7” comes closer to the reach line Le1 in which “7” symbols are arranged on the left and right. In this case, the “7” symbol on the reach line Le1 The “7” symbol and the “7” symbol, which is the middle symbol, are normally displayed, and the other symbols are subjected to translucency processing.

  In this reach pattern, the number of symbols displayed on the display screen G increases and the number of effective lines increases. However, since the translucency processing is performed as described above, it is easy to understand which reach line is likely to have the jackpot symbols. Thus, for the player, it is only necessary to pay attention to only the corresponding part.

  Then, as shown in FIG. 57 (c), when the final stop symbol is stopped at “6” or “7” symbol and displayed on any reach line, the boy character informs that a big hit has occurred. Is done. Even if the super-reach is developed as described above, if the final stop symbol does not stop at the winning symbol (in this example, “6”, “7” symbol), the boy character does not win the jackpot. The occurrence is notified.

  Incidentally, when the “7” symbol stops on the reach line Le4, the “6” symbol stops on the reach line Le2, and a jackpot combination occurs on the two effective lines. In this case, the jackpot symbol is determined according to a rule defined in advance. In the present embodiment, it is set so that a combination of “7” symbols, which is a high probability symbol, is adopted as an effective jackpot combination. On the display screen G, when the “7” symbols are likely to be aligned on the reach line Le4, the “6” symbols are likely to be aligned on the reach line Le2 (in the case of FIG. 57 (a)), this is effective. Since the jackpot symbol is the “7” symbol, the “7” symbol is normally displayed, whereas the “6” symbol is subjected to a translucent process.

  In FIGS. 56 and 57, when the cross line reach occurs in the main display region Rm, the pattern 6 shifts to the reach pattern 6 so that the cross line reach occurs two times in the vertical direction. However, the reach pattern of the pattern 6 may be shifted from the form in which the reach of the horizontal line is generated. In the following, an example of shifting from the form in which the horizontal line reach occurs will be described with reference to FIGS. 59 and 60. FIG. Since the main flow of the reach display mode is the same, only different situations are shown in FIGS. 59 and 60. FIGS. 59 (a) and 60 (a) are the same as FIG. 56 (a). FIGS. 59B and 60B correspond to the scene of FIG. 56C, respectively.

  In FIG. 59 (a), in the main display area Rm of the display screen G, after the symbols of the symbol rows Z1 to Z3 normally change, the change display of the left symbol and the right symbol is temporarily stopped, and the reach line Lf1 is a horizontal line. Reach occurs above. In the reach line Lf1, the left and right symbols are “6” symbols, and the reach line Lf1 corresponds to the lower line L3 described in FIG. At this stage, both the right door 171 and the left door 172 remain closed. When the reach display occurs, the boy character displayed in the center area of the sub display area Rs (the third notice area Rs3 described with reference to FIG. 29) notifies that the reach has occurred.

  Thereafter, the boy character performs an effect of hitting the lower part of the sub display area Rs with a mallet, and the left and right doors 171 and 172 are opened as shown in FIG. By opening the left and right doors 171 and 172, the right and left regions (first and second notice regions Rs1 and Rs2 described in FIG. 29) of the sub display region Rs are hidden behind the doors 171 and 172. The main symbol appears. At this time, symbols that are contrary to the periodicity of the left symbol and the right symbol are displayed in the right region and the left region of the sub-display region Rs. On the contrary, a “7” symbol appears above the “5” symbol, and a “5” symbol appears above the “7” symbol even in the right symbol row Z3 arranged in ascending order. As a result, apart from the reach line Lf1, a reach line Lf2 consisting of a “5” symbol and a reach line Lf3 consisting of a “7” symbol are generated, and a total of three reach lines are generated simultaneously. At this time, it seems that the reach of the cross line and the reach of the horizontal line are generated up and down. The reach lines Lf2 and Lf3 correspond to the effective lines L12 and L13 described with reference to FIG. The following development is the same as that shown in FIGS.

  On the other hand, in FIG. 60 (a), in the main display area Rm of the display screen G, after the symbols in the symbol rows Z1 to Z3 have normally changed, the change display of the left symbol and the right symbol is temporarily stopped to reach the horizontal line. Reach occurs on line Lg1. In the reach line Lg1, the left and right symbols are “1” symbols, and the reach line Lg1 corresponds to the upper line L1 described in FIG. At this stage, both the right door 171 and the left door 172 remain closed. When the reach display occurs, the boy character displayed in the center area of the sub display area Rs (the third notice area Rs3 described with reference to FIG. 29) notifies that the reach has occurred.

  Thereafter, the boy character performs an effect of hitting the lower part of the sub display area Rs with a mallet, and the left and right doors 171 and 172 are opened as shown in FIG. By opening the left and right doors 171 and 172, the right and left regions (first and second notice regions Rs1 and Rs2 described in FIG. 29) of the sub display region Rs are hidden behind the doors 171 and 172. The main symbol appears. At this time, symbols that are contrary to the periodicity of the left symbol and the right symbol are displayed in the right region and the left region of the sub display region Rs. In the left symbol row Z1 that is arranged in descending order, the original arrangement order is displayed. On the other hand, a “1” symbol appears above the “1” symbol, and even in the right symbol row Z3 arranged in ascending order, a “1” symbol further exists above the “1” symbol against the original arrangement order. appear. As a result, apart from the reach line Lg1, reach lines Lg2, Lg3, and Lg4 each having a “1” symbol are newly generated, and a total of four reach lines are simultaneously generated. At this time, it seems that the reach of two horizontal lines and the reach of a cross line overlap. The reach lines Lg2, Lg3, and Lg4 correspond to the effective lines L11, L12, and L13 described with reference to FIG. The following development is the same as that shown in FIGS.

  The display example of FIG. 60 will be further described. One main symbol (for example, “1” symbol at the top of the left column) is combined with a plurality of other main symbols (for example, two “1” symbols in the right column). A reach line is formed by a plurality of active lines. Normally, when the reach is established, the relationship between the left and right main symbols is 1: 1, whereas in this display example, the relationship between the left and right main symbols is 1: n (here, 1: 2). can do. Therefore, it is possible to perform an unexpected display for the player. In this case, the player can greatly expect the occurrence of the special gaming state by recognizing that the player is in a special state (a state that is not normal).

  In each of the above reach patterns, when the final stop symbol is confirmed and displayed on the display screen G, the opened right door 171 or left door 172 is closed and the display screen G is again displayed as the main display region Rm. The area is divided into sub-display areas Rs. That is, the main display area Rm is reduced to the original state.

  Incidentally, the reach patterns of the patterns 1 to 6 are different in the selection rate when the jackpot is generated, and the latter reach pattern is configured to be more easily selected when the jackpot occurs. On the other hand, there is also a difference in reach selection rate when no big hit occurs, and the former reach pattern is more easily selected. This is a device that enhances the interest of the game by associating the degree of unexpectedness that the player has with respect to the change in the shape and size of the main display area Rm and the occurrence of the jackpot.

  Further, in this display control, a reach notice for notifying that the reach display is performed and a jackpot notice for notifying the occurrence of the jackpot are implemented as the notice effects. I will explain. These notice effects are performed, for example, at the time of normal fluctuation of the first symbol. For convenience of explanation, (a) to (d) in FIG.

  First, in the notice 1 shown in FIG. 61A, a flame lump appears in the main display area Rm during normal fluctuation of the first symbol, and the flame circulates clockwise from the upper right corner of the main display area Rm. Then, after the first symbol in the right symbol row Z3 is variably displayed at high speed so as to be enveloped in flame, reach display is performed.

  Also, in the notice 2 shown in FIG. 61 (b), the right door 171 is opened during the normal variation of the first symbol, and the reach notice is given to the right area of the sub display area Rs (the first notice area Rs1 described in FIG. 29). A character (a strawberry character that relaxes by drinking tea in the present embodiment) is displayed. The right door 171 is temporarily opened and then closed again. Thereafter, reach display is performed by variably displaying the first symbol in the right symbol row Z3 so as to be surrounded by flame.

  The advance notice 3 shown in FIG. 61 (c) is an advanced advance notice of the advance notice 2, and after the right door 171 is opened and the saddle character is displayed, before the right door 171 is closed, it is behind the saddle character. A flame is generated. The flame circulates in the main display area Rm in the clockwise direction, and at the same time, the fire ignites on the back so that the samurai character strikes and flutters and falls from the right area of the sub display area Rs to the main display area Rm. Go. Thereafter, reach display is performed by variably displaying the first symbol in the right symbol row Z3 so as to be surrounded by flames.

  In notice 4 shown in FIG. 61 (d), the left door 172 is opened at the time of normal fluctuation of the first symbol, and the reach notice character ( In the present embodiment, a plurality of cat characters having an oval) are displayed. The left door 172 is temporarily opened and then closed again. After the cat character is displayed, at least one cat character falls from the left side region of the sub display region Rs to the main display region Rm at regular intervals regardless of whether the left door 172 is opened or closed. After that, reach display occurs.

  In the above notice 1 to notice 4, the degree of jackpot expectation associated with its appearance is determined in advance. For example, the expectation of jackpot increases in the order of notice 1 → notice 2 → notice 3 → notice 4. In addition, when reach display occurs after the same announcement effect is repeatedly performed a plurality of times, display control can be performed so that the degree of expectation of jackpot is further increased or the jackpot is confirmed.

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

  As explained as pattern 5 in each reach pattern of the display control, even if the first two symbols are temporarily stopped and reach display is not performed, the subsequent opening of the left and right door bodies 171 and 172, and Since the display is shifted to the reach display by the slide, the interest of the game can be enhanced. In general, the player considers whether a reach line is generated other than the active line, and if the player is in a situation where it occurs, the player regrets that the reach line is not on the active line. In the pachinko machine 10, the left and right doors 171 and 172 are opened to notify the player that a reach line other than the active line is generated, and the reach line is slid onto the active line. This is exactly the ideal development envisioned by the player, and as things have progressed as expected, the expectation for jackpots will also increase. In addition, when a jackpot occurs, everything went as the player imagined, and the joy of the jackpot becomes exceptional. Further, since the reach pattern of pattern 5 is initially developed from a state where no reach occurs in the main display area Rm, the player always expects to develop to reach even in a situation where no reach occurs. While playing games.

  As explained as pattern 6 in each reach pattern of display control, once reach display is made, the left and right doors 171 and 172 are opened, and the left and right first symbols appear against the regularity (array). Since the reach line is additionally increased, the combination of jackpots increases, the player can feel closer to the jackpot, and the fun of the game can be further enhanced. In addition, even when it is determined that there is no player, it is possible to newly generate an expectation for a big hit (special game state).

  Especially in the production using the left and right door bodies 171 and 172 on the display screen G as in the present embodiment, the player is not only surprised that the left and right door bodies 171 and 172 are opened, but the player's It is also surprising that an unexpected pattern appears from behind the door bodies 171 and 172. Because of these surprises, the player expands a sense of expectation for the jackpot, so that the interest of the game can be enhanced.

  In the variable display unit 35, the operations of the right door 171 and the left door 172 provided on the display screen G of the first symbol display device 41 are controlled by an audio lamp control device 272 having a power system different from that of the display control device 214. Therefore, when changing the design of the right door 171 and the left door 172 due to a model change or the like, it is only necessary to change the design of the power supply system of the right door 171 and the left door 172 on the sound lamp control device 272 side. Is not forced on the display control device 214 side. That is, the display control device 214 only needs to change the control specifications for display effects. As a result, it is possible to reduce the design man-hours of the display control device 214 at the time of model change in the pachinko machine 10 which is intended to improve the interest of the game by performing the auxiliary effect. In addition, by adopting a different power supply system as described above, even if a power supply voltage fluctuation or noise occurs on the sound lamp control device 272 side that controls the right door 171 and the left door 172, the display control device 214 side thereof The influence on can be suppressed.

  Further, when the display control device 214 controls the variation display of the first symbol, the control of the right door 171 and the left door 172 is left to the sound lamp control device 272 different from the display control device 214, and the display An increase in the processing load of the control device 214 can be prevented.

  The right door 171 and the left door 172 are spaced apart from the corners of the display screen G, and at that time, the display areas of the longest portions in the vertical and horizontal directions on the display screen G are left. Yes. Therefore, even if a concealing member is provided over the display screen G, the impression that the display screen G is reduced is relatively small. Therefore, even when the display effect of the first symbol is performed by combining the operations of the right door 171 and the left door 172, a suitable display effect can be realized while using the display screen G effectively. For example, even if a relatively large display screen is adopted as the first symbol display device 41, the inconvenience that the large screen is not fully utilized can be solved.

  In the reach production, the player can easily imagine the reach pattern from the production by the door bodies 171 and 172 by making the opening pattern and the reach pattern of the right door 171 or the left door 172 correspond one-to-one or one-to-two. Can increase the interest of the game.

  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-described embodiment, the variable display unit 35 is configured to rotate the right door 171 and the left door 172 in the left-right direction around the left or right shaft portions 171a and 172a (FIG. 5). , See the configuration of FIG. 6), the shaft portion of each door 171, 172 may be provided at the upper end portion thereof and rotated in the vertical direction. The doors 171 and 172 may be configured to slide on the display screen G of the first symbol display device 41.

  (B) In the above embodiment, in the variable display unit 35, two pieces of the rectangular plate-shaped right door 171 and left door 172 are provided on the display screen G as concealing members, but this configuration is changed. FIG. 62 shows a modification thereof. In FIG. 62A, the concealing member 195 made of, for example, a plate-like door is not a quadrangle but another polygon (a pentagon in the figure). In (b), the concealing member 196 has a shape having an arc. In (c), concealment members 197 are provided at the four corners of the display screen G, respectively. Further, in (d), the concealment member 198 is integrally provided so as to extend along the upper side portion of the display screen G, and as a display area expansion portion in order to reduce the portion concealing the display screen G at the center. The notch 198a is provided. In the case of (d), if the concealing member 198 is constituted by a door body, it is preferable to provide a shaft portion at the upper end portion thereof and rotate in the vertical direction. In addition to the above (a) to (d), it is also possible to adopt a configuration in which a plurality of concealing members provided on the left and right or top and bottom are asymmetrical, a configuration in which three-dimensional undulations or protrusions are provided on the surface of the concealing member, and the like. It is.

  (C) In the above embodiment, the audio lamp control device 272 is provided as a subordinate to the display control device 214, and the control is performed according to the control command from the display control device 214, but this configuration is changed. For example, the audio lamp control device 272 is provided as a subordinate to the main control device 271 instead of the display control device 214. That is, the sound lamp control device 272 performs control according to the control command from the main control device 271. In this case, control of voices and lamps and movements of the right door 171 and the left door 172 are directly managed by the main controller 271.

  (D) The lamps (light emitters) and the voices are controlled by different systems, and the movement of the right door 171 and the left door 172 is controlled by a lamp control device for controlling the lamps. It is good also as a structure. Auxiliary effects by lamps are relatively often changed in design as the model of the pachinko machine is changed. This is true even when compared to the auxiliary production of voices. In this configuration, in the control device for lamp control, the design change for the right door 171 and the left door 172 is made together with the lamps, so that it is possible to minimize the control device to be changed. .

  (E) It is good also as a structure which controls operation | movement of the right door 171 and the left door 172 as a concealment member by another control apparatus on the condition that it is different from the display control apparatus 214. A configuration in which a dedicated device (dedicated chip) for controlling the operation of the concealing member is also possible.

  (F) The display control means and the concealing member control means may be embodied by the same control device. For example, both the control means may be realized by the display control device 214.

  (G) In addition to displaying a predetermined number of first symbols on the active line in the main display region Rm of the display screen G, a part of the first symbol is separately displayed at the boundary of the main display region Rm. It is good also as a structure displayed so that visual recognition is possible. In this case, only a part of the first symbol deviating from the main display area Rm can be seen, so that it is possible to give the player the impression that it was a little more reach by combining with this deviating symbol. Yes, by shifting from this state to reach display, the player's interest can be further enhanced.

  (H) In the reach pattern of the pattern 5 described with reference to FIGS. 54 and 55, the reach lines Ld1 and Ld2 are slid downward to come to positions corresponding to the effective lines L4 and L5. It is good also as a structure which does not slide Ld2. In this configuration, as shown in FIG. 54 (c), when the right door 171 and the left door 172 are opened and the reach lines Ld1 and Ld2 are generated, the reach effect is performed as it is. In this case, since the reach lines Ld1 and Ld2 are different from the original effective lines L1 to L5, display control may be performed so that new effective lines are added.

  (I) In the reach pattern of the pattern 6 described in FIG. 56 and FIG. 57, when the right door 171 and the left door 172 are opened, the main symbols constituting a new reach line appear from both behind the right door 171 and the left door 172. However, it is not limited to this configuration. For example, in FIG. 56 (c), when the right door 171 and the left door 172 are opened, the "7" symbol appears as the left symbol and the "7" symbol appears as the right symbol from behind (however, The right symbol is optional unless the symbol is “6”. In this case, the reach line Le4 is established, but the reach line Le3 is not established. Even in such display control, the reach line is increased as the right door 171 and the left door 172 are opened, and the interest of the player is enhanced. In addition, if the reach line increases only on one side with the opening of the right door 171 and the left door 172, the door body (the right door 171 in the previous example) on which the reach line does not increase is configured not to open. Is also possible.

  (J) In the above embodiment, in the reach pattern of pattern 6, the number of effective lines can be increased by 3 lines from the initial 5 lines. However, a structure in which more effective lines are added may be used. Actually, as shown in FIG. 58 (b), on the display screen G, as the right door 171 and the left door 172 are opened, the first symbol is displayed in five vertical columns in the left and right symbol rows. In this case, a maximum of 6 lines can be increased, and the total number of effective lines can be 11 lines.

  (K) The display screen G may be configured such that the main display area Rm and the sub display area Rs are not divided into areas. In such a case, for example, in the configuration in which five effective lines are set in advance on the display screen G as described above, at least one of the effective lines is partially hidden by the right door 171 and the left door 172, and the other lines are hidden. Keep it visible at all times. And it is set as the structure which increases the number of visible effective lines according to predetermined conditions. For example, in the configuration in which the first symbol is displayed in the upper and lower three stages on the display screen G and the upper one stage is hidden by the right door 171 and the left door 172, normally two effective lines can be visually recognized. By opening the door 171 and the left door 172, it is possible to change so that five effective lines can be visually recognized.

  (L) In the above-described embodiment, various reach patterns have been described for the pachinko machine 10 provided with the pair of left and right door bodies 171 and 172 on the display screen G. However, the pachinko machine without the door bodies 171 and 172 has been described above. It is also possible to apply each reach pattern. For example, in the case of the reach pattern of pattern 5, a main display area Rm and a sub display area Rs are provided on the display screen G as described above, and they are not originally effective lines but are exceptionally displayed in the sub display area Rs. It is set as the structure which generates a reach line using the made 1st symbol. At this time, the reach display may be used as it is, or the reach line may be slid into the main display area Rm. Further, in the case of the reach pattern of pattern 6, the first design contrary to the arrangement is displayed in the sub-display area Rs, and a reach line is additionally generated using the displayed first design.

  (M) In the above embodiment, as described in the reach pattern of pattern 6, when a jackpot combination occurs on two effective lines, a combination of high probability symbols is adopted as an effective jackpot combination. Although comprised, it is good also as a structure which alert | reports which combination was effective after the jackpot state end. In this case, the player's thrilling feeling continues until the jackpot state ends, so that it is possible to enhance the interest of the game.

  (N) In the above embodiment, after the symbols of each symbol row Z1 to Z3 normally fluctuate, the left and right symbols fluctuate display once and then shift to various reach patterns. For example, after reaching the reach pattern of pattern 2, it may be configured to proceed to the reach pattern of pattern 3 and then to the reach pattern of pattern 4. In such a configuration, the shape of the super reach and the symbol display area is continuously changed, so that it is possible to enhance the interest of the game.

  (O) In the above-described embodiment, the first symbol is variably displayed in the vertical direction on the display screen G of the first symbol display device 41. It goes without saying that the effect of can be obtained.
