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 the area of the guide passage that is the 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. This will be described as the excluded area. In other words, since the game area does not include the guide passage portion, the left limit position toward the game area is specified not by the outer rail part 52 but by the inner rail part 51. 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 game 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 may be 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. 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 external shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 has to be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more. In order to secure 80% or more, it is difficult to make the shape of the game area into a substantially circular shape. Therefore, it is preferable to have a shape in which the corner (for example, the lower right corner or the upper right corner) is expanded. .

  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 before. The area ratio of the game area to the area of the front side of the entire pachinko machine 10 is desirably 35% or more. Of course, it may be 40% or more, 45% or more, or 50% or more.

  In connection with the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable prize-winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided 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.

The speed reduction part 565 is configured by providing concave and convex parts respectively on part of the rail unit 50 and the center frame 43. A step portion 566 is formed at the right end portion of the outer rail portion 52 of the rail unit 50. A return rubber 55 as a buffer member is attached to the step portion 566, and the game ball guided by the ball guide passage 564 collides with the return rubber 55 and bounces back to the ball guide rib 563 side of the center frame 43. It is supposed to be. A plurality of convex portions 567 a and 567 b are formed vertically below the step portion 566, that is, on the upper right side of the inner rail portion 51. The convex portions 567a and 567b are formed in an arc shape toward the center of the game area. Therefore, the game ball that has fallen into the ball guide passage 564 collides with the convex portions 567 a and 567 b and is bounced back to the ball guide rib 563 side of the center frame 43.

  A plurality of recesses 569a, 569b, and 569c are formed in the ball guiding rib 563 so as to be arranged vertically. The recesses 569a, 569b, and 569c are formed in an arc shape toward the center of the game area. Therefore, the game ball that has fallen into the ball guide passage 564 collides with the recesses 569a, 569b, and 569c, and is bounced back to the rail unit 50 side. The concave portions 569a, 569b, and 569c are formed so as to correspond to the step portion 566 and the convex portions 567a and 567b of the rail unit 50. A concave portion 569a corresponds to the step portion 566, a concave portion 569b corresponds to the convex portion 567a, and a concave portion 569c corresponds to the convex portion 567b. For this reason, the passage width of the portion of the ball guide passage 564 where the speed reducing portion 565 is provided is also kept approximately the same. The ball guide passage 564 is a meandering passage from approximately the center position to the exit. In addition, since the speed reduction part 565 is a part to which an impact is applied particularly from the game ball, a through-hole 561 is provided on the expansion plate part 553 in the vicinity of the speed reduction part 565 to counter the impact from the game ball. A screw or the like is inserted into the hole 561.

  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). Therefore, the game ball launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the guide passage. As described above, the curvature of the guide passage is reduced because the game area has been greatly expanded as compared with the prior art, and thus a device for stabilizing the launch ball is required. Therefore, in the present embodiment, the launch position of the game ball is lowered so that the inclination angle (launch angle) of the launch rail 61 is somewhat larger than the existing one (that is, the launch rail 61 is raised), and By forming the launch rail 61 so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area, the launch rail 61 is made longer than the existing one and sufficiently long. The ball guide distance is secured. Thereby, the game ball launched from the game ball launching device can be guided to the 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 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 guide passage, the foul ball passes through the foul ball passage 76 to the lower plate 16. 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 guide passage, most of them flow along the outer rail portion 52 and fall downward when reaching the lower end of the outer rail portion 52, but some foul balls are guided. There is also a thing that rampages in the passage and jumps to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the 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.

  In addition, a pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 14) 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. This small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, and through the relay terminal hole 59 and the small window 79, the relay installed on the back of the game board. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 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. 9) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 12 side for grounding. Therefore, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

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

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

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

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 9 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape that is nearly circular, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape. Above the window part 101 of the front door frame 13, the frame width of the narrowest part is about 61 mm. The frame width dimension in the present embodiment is substantially the same as the distance between the uppermost part 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 This 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 sufficient width dimension 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 guide passage overlaps and is covered with the left frame portion of the front door frame 13. However, even if it is difficult to visually recognize the game ball in the guide passage, the guide passage is only a passing area until the game ball is guided to the game area, and in the game area where the player mainly enjoys the game. The game ball is not difficult to see. 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 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, the small window 107 can be provided with a magnifying lens portion so that the hall operator or the like can easily see the internal certificate paper or the like.

  The front door frame 13 is provided with light emitting means such as various lamps around the periphery (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking 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. A protrusion (or a wavy protrusion) is provided in the direction of the protrusion. The outer resin cover layer is transparent, and the inner resin cover layer is colored. Therefore, if the annular illumination part 102 is caused to emit light, it is possible to realize the illumination in a state of being dispersed in a large number or in a state accompanied with a stereoscopic effect. A resin material containing glass powder may be used for the resin cover layer. Such a configuration of the resin cover layer can also be applied to other electric decoration parts (for example, the central electric decoration part 103 and the prize ball lamp 105).

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and 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 (ball lending unit) arranged on the side of the pachinko machine 10. it can. That is, the ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is paid out as long as the remaining amount exists on the card or the like. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. In addition, in a pachinko machine (so-called cash machine) in which game balls are lent out directly from a ball lending device or the like 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 pachinko machine 10 provided with the ball rental 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. 9, 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.

  9 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 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. 9) is flat, and forms the side wall of the firing rail 61 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 61.

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

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

  As described above, in the pachinko machine 10 according to the present embodiment, the game area is expanded. Therefore, when the front door frame 13 is closed, the guide passage formed between the inner and outer rail portions 51 and 52 is provided. Is partially covered by the front door frame 13. Therefore, in the guide passage, a portion where the open side on the front side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the guide passage or between the outer rail portion 52 and the glass 137. There is a risk of getting caught in a gap. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the opening portion on the near side of the 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 guide passage, and covers a section from the proximal end portion of the guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. . 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. 9 where the rail cover 140 is attached to the front door frame 13), the portion where the guide passage protrudes from the side edge portion of the glass 137 is provided. A covering portion 141 for covering is provided. With the configuration of the rail cover 140 described above, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide passage, so that the game ball jumps out of the guide passage, Generation | occurrence | production of the malfunction of being pinched in the clearance gap formed between the rail part 52 and the glass 137 can be prevented.

  Further, on the lower back side of the rail cover 140, a ridge 142 that extends in an arc shape along the inner edge and protrudes rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the 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 or the like may enter the game area inside the guide passage. It 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. 10 is a rear view of the pachinko machine 10, and FIG. 11 is an exploded perspective view showing the rear structure of the pachinko machine 10 for each major part.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. On the back side of the pachinko machine 10, various control devices (various control boards) are arranged so as to be lined up and down, left and right, or stacked in front and back, and a game ball supply device for supplying game balls (Discharge mechanism), a protective cover made of resin, and the like are attached. In the present embodiment, various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) 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.

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

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

  The sound lamp control device 272 includes, for example, a CPU for controlling sound and lamp display in accordance with instructions from the main control device 271 or the display control device 214, and a sound lamp control board including ROM, RAM, various ports, and the like.

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

  In addition, in the mount 251, a shielding part 257 for shielding an opening leading to the back space of the substrate mounting surface 252 is provided below the main substrate mounting surface 252. 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 board 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. The locked state of the fixture 277 cannot be illegally released.

  As described above, the first control board unit 201 cannot be removed unless the back pack unit 203 is opened at a predetermined angle or larger, or the unit 203 is not removed. The 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. That is, if the main body frame 12 cannot be opened, the first control board unit 201 cannot be rotated or removed as a result, and the main controller 271 cannot be removed. Therefore, unauthorized replacement or theft of the main controller 271 can be effectively prevented.

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

  Here, the display content of the 1st symbol display apparatus 41 is demonstrated based on FIG.

  In the first symbol display device, three symbol sequences of left, middle, and right are set. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-symbol made of, for example, a diamond-shaped picture. Each main symbol and sub-design constitute a first symbol. In each symbol row, main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. That is, each symbol row is provided with a total of 20 first symbols of 10 main symbols and 10 sub symbols. On the first symbol display device 41, 20 first symbols for each symbol row are variably displayed so as to scroll from top to bottom with periodicity. In particular, the numbers of the main symbols appear in descending order in the left symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the right symbol row. The first symbol display device 41 is configured to display first, middle, and lower three first symbols for each symbol row. Accordingly, the first symbol display device 41 displays a total of nine first symbols of 3 rows × 3 columns. In the first symbol display device 41, 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. Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, it is a combination of jackpot symbols on any active line (in this embodiment, the same main symbol combination) If you arrange it, a big hit video will be displayed as a big hit.

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

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

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). The values of the jackpot random number counter C1, the jackpot 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 high probability 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 big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state.

  The jackpot symbol counter C2 determines the symbol when the fluctuation of the first symbol display device 41 is stopped in the case of a jackpot. 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. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

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

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented one by one within a range of 0 to 240 and reaches 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. The second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. 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 combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the first symbol display device 41 starts the variation of the first symbol.

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

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

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

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

  FIG. 35 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 271 every 2 msec, for example.

  In FIG. 35, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 271 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

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

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. The start winning process will be described with reference to the flowchart of FIG. 36. In step S701, whether or not the game ball has won the start opening 33 (start winning prize) is determined based on the detection information of the operation opening switch 224. 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 area of the free storage 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 operation opening 33 (start winning prize), the first symbol display by the first symbol display device 41 is started accordingly, but after the start winning, the first symbol changes. However, there is a restriction that a predetermined time (for example, 5 seconds) must elapse before the symbol is stopped. Therefore, in the start winning process, when a start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S704). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and the variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed). .

  FIG. 37 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 37 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within the predetermined time.

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

  The above NMI interrupt processing is similarly executed in the payout control device 311, and the state of the payout control device 311 when the power is shut down due to the occurrence of a power failure or the like is stored in the backup area 513 a of the RAM 513 by the NMI interrupt. Similarly, power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 37 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 30 is a flowchart showing an example of a main process executed by the CPU 501 in the main controller 271. This main process is started upon reset when the power is turned on.

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

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

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

  In the normal process, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, when the first symbol display device 41 displays the variation of the first symbol, a stop symbol command, a variation pattern command, a confirmation command, and the like are 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. 32, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. It is determined whether or not it is time to update the symbol counter CM symbol symbol CM. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both NO in steps S301 and S302), the process proceeds to step S305, and the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR. According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

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

  After update processing of the off symbol counters CL, CM, and CR, in step S204 in FIG. 31, a prize ball counting signal and a 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. 35, 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, it is possible to update the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. 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 further 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 actuated balls on the first symbol display device 41 is greater than zero. Then, when the jackpot is being hit or the number N of the 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. 34. 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 checked, 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. 33, 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. 38 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

  First, 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 occurrence information of the 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 513 (steps S915 to S918). . That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S909, the stack pointer prior to power shutdown is restored, and in step S910, information on occurrence of power shutdown is cleared. In step S911, the CPU peripheral device is initialized, and in step S912, the used register is restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the 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. 39, in step S1001, a command from the main controller 271 is acquired, and the total number of winning balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

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

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

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

  In the lending process, if the lending is not disabled and a lending request from the card unit is received (step S1010 is NO, S1011 is YES), the process proceeds to step S1012 and 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. 40, 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, 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.

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

  In the ball lending control process shown in FIG. 41, in step S1201, the payout motor 358a is driven to execute lending of a lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 to drive the payout motor 358a to execute a retry process and stop 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, the characteristic operation of the pachinko machine 10 configured as described above is centered on the operation based on the configuration of the speed reducing portion 565 provided in the ball guide passage 564 formed by the rail unit 50 and the center frame 43 described above. Will be described.

  In FIG. 4, when a game ball is launched from the game ball launcher, the game ball is guided to the game area through a guide passage for guiding the game ball 30 onto the game board 30. The center frame 43 is provided with a ball retaining rib 562 and a ball guiding rib 563 so that a game ball is guided to the left side of the game area and a game ball is guided to the right side of the game area. It has become. In other words, the game ball launched to the ball retaining rib 562 is bounced back to the ball retaining rib 562 and falls to the left side of the game area, and the game ball launched to the ball proposing rib 563 side is It is guided by the rib 563 and falls to the right side of the game area. Therefore, when a game ball is launched to the right side of the game area, it always passes through the ball guide passage 564 constituted by the ball guide rib 563.

  In FIG. 7, the game ball guided to the ball guide passage 564 first hits the return rubber 55 of the step portion 566. The game ball hitting the return rubber 55 is then bounced back toward the recess 569a of the ball guiding rib 563 and hits the recess 569a. The game ball that hits the concave portion 569a is then bounced back toward the convex portion 567a of the inner rail portion 51 and hits the convex portion 567a. The game balls hitting the convex portions 567a then alternately hit the concave portions of the ball guiding ribs 563, the convex portions 567b of the inner rail portion, and the concave portions 569c of the ball guiding ribs 563, and are discharged from the outlet of the ball guiding passage 564. The game ball released from the exit of the ball guide passage 564 hits a decorative lamp 550 provided immediately below the exit of the ball guide passage 564, and then moves to the center of the game area. In this way, the game balls passing through the ball guide passage 564 fall while alternately hitting the speed reduction unit 565 constituted by the rail unit 50 and the center frame 43, so that the falling speed of the game balls is suppressed.

  According to the embodiment described in detail above, the rail unit 50 and the center frame 43 form the ball guide passage 564, and the ball guide passage 564 has a step portion 566, projections 567a and 567b, recesses 569a, 569b, Since the speed reducing portion 565 is configured by providing 569c, the falling speed of the game ball can be suppressed without relying on the obstacle nail. Since the speed reducing portion 565 is configured without relying on the obstacle nail, the falling speed of the game ball falling in a place where it is difficult to provide the obstacle nail or a place where the obstacle nail is not desired can be suppressed.

  In addition, it is possible to suppress the falling speed of the game ball even in the right side of the game area where it is difficult to provide the obstacle nail by enlarging the variable display unit 35, and the right side of the game area can be used effectively. You can entertain the behavior of game balls.

  Also, since the falling speed of the game ball can be suppressed at the right side of the game area, it does not collide with the decorative lamp 550 provided at the lower right side of the game area. Therefore, the decorative lamp 550 can be protected from damage or the like.

  In addition, since the speed reducing portion 565 is provided at a portion of the ball guide passage 564 that extends vertically with respect to the game area, that is, a portion where the game ball falls relatively quickly, the fall speed of the game ball is more effectively suppressed. be able to.

  Further, since the speed reducing portion 565 is configured without relying on the obstacle nail, it is possible to reduce the parts cost and processing cost of the obstacle nail, and to reduce the cost in manufacturing the pachinko machine 10. In particular, in the pachinko machine 10 in which the game area is expanded, when the same number of obstacle nails as in the conventional pachinko machine are used, the implantation interval of the obstacle nails is widened, and the falling direction of the game ball is preferably dispersed and adjusted. I can't. Therefore, in order to disperse and adjust the falling direction of the game ball appropriately, it is necessary to add obstacle nails. Increasing obstacle nails increases the parts and processing costs, which is disadvantageous in manufacturing. However, by using the rail unit 50 and the center frame 43, the number of obstacle nails used can be reduced, and the cost of the pachinko machine 10 can be reduced.

  Further, since the speed reduction portion 565 is integrally formed with the rail unit 50 and the center frame 43 formed of synthetic resin, the speed reduction portion 565 can be formed simultaneously with the formation of the rail unit 50 and the center frame 43 by using a predetermined mold. it can.
