According to the gaming machine of the present invention, there is an effect that it is possible to reduce the fraud using illegal substrate.

  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail based on the drawings. FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view showing a state in which an inner frame 12 and a front frame set 14 are opened with respect to an outer frame 11 to be described later.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is supported on one side of the outer frame 11 so that the inner frame 12 can be opened and closed. Has been. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, compared with the conventional structure which assembled | attached each board | plate material using the nail and the rivet, the reuse of a structural member is made easy. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm). In addition, you may make it comprise the outer frame 11 with light metals, such as resin and aluminum.

  The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile butadiene styrene) resin. ABS resin is suitable as a constituent material of the inner frame 12 because it has a low material cost, has a good paste such as plating, has a good decorative property, and has a high impact resistance. The opening / closing axis of the inner frame 12 extends vertically from the front of the pachinko machine 10 to the opposite side of the place where the game ball launching handle 18 is installed, and the inner frame 12 is directed forward with the opening / closing axis as the axis. It can be opened. Since the opening / closing axis is provided on the opposite side of the game ball launching handle 18, the inner frame 12 can be greatly opened. Normally, in the pachinko hall, the pachinko machines 10 are arranged adjacent to each other. Therefore, when the opening / closing axis is provided on the game ball launching handle 18 side, the game ball launching handle 18 that is opened together with the inner frame 12 is opened. This is because the amount of opening is reduced due to contact.

  A lower tray unit 13 is attached to the inner frame 12 at the lowermost portion, and a front frame set 14 is attached so as to cover the inner frame 12 in a range excluding the lower tray unit 13. The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. The front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 is located on the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened. An outer peripheral wall projecting toward the front side is formed on the outer periphery of the inner frame 12, and a front frame set 14 is disposed inside the outer peripheral wall. That is, when the front frame set 14 is attached to the inner frame 12, the outer periphery of the side surface of the front frame set 14 is surrounded by the outer peripheral wall of the inner frame 12. It is possible to suppress illegal acts by making it difficult to insert a wire or the like.

  On the upper part of the inner frame 12, a push button type opening / closing switch 25 protruding in a columnar shape is provided. The open / close switch 25 is a switch for detecting the open / closed state of the front frame set 14. When the front frame set 14 is closed with respect to the inner frame 12, the open / close switch 25 is pressed, and conversely, when the front frame set 14 is open with respect to the inner frame 12, the open / close switch 25. Is in a non-pressing protruding state and detects the open / closed state of the front frame set 14. A wiring hole 26 is formed in the upper left portion of the inner frame 12 (see FIG. 2). The wiring hole 26 is a hole for wiring the wiring of the front frame set 14 through the inner frame 12 to the back surface of the game board 30. R is formed at the corner of the wiring hole 26 so that each cord wired in the wiring hole 26 is not damaged at the corner. As shown in FIG. 4, a wiring hole 37 is also formed in the upper left part of the game board 30 corresponding to the wiring hole 26.

  FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10. In FIG. 3, for the sake of convenience, the configuration in the game area on the surface of the game board 30 is shown as blank. As shown in FIG. 3, the lower tray unit 13 is provided with a lower tray 15 as a ball receiving tray at a substantially central portion so that game balls discharged from the outlet 16 can be stored in the lower tray 15. Yes. Similar to the inner frame 12, the lower dish unit 13 is formed of flame-retardant ABS resin. It is not always necessary to form all of the lower plate 15 with ABS resin, but at least the surface portion of the lower plate 15, that is, the surface layer of the lower plate 15 and the front panel behind the lower plate 15 are formed with ABS resin. It is preferable. Since there is a danger that the lit cigarette will be left in the lower plate 15, it is possible to prevent damage to the pachinko machine 10 and the occurrence of fire by forming at least the surface portion thereof with flame retardant ABS resin. It is. The front panel has a large number of speaker holes 24 for outputting sound from the speakers.

  In the lower part of the front of the lower plate 15, a ball removal lever 17 is provided for operating when the game balls stored in the lower plate 15 are discharged downward. The ball release lever 17 is always urged to the right, and by sliding it to the left against the urge, the bottom opening formed on the bottom surface of the lower plate 15 opens, A game ball naturally falls from the bottom opening and is discharged. The operation of the ball pulling lever 17 is usually performed in a state where a box (generally referred to as “thousand box”) for receiving game balls discharged from the lower plate 15 is placed below the lower plate 15. In addition, a game ball launching handle 18 is disposed on the right side of the lower plate 15 in a state of protruding from the lower plate unit 13 toward the front side, and an ashtray is mounted in a cantilevered manner on the left side of the lower plate 15. It is worn. The ashtray is rotatable in the front and back directions together with a shaft rotatably attached to the lower plate 15. Thus, by arranging the game ball launch handle 18 on one side of the lower plate 15 and the ashtray on the other side, the decorativeness of the pachinko machine 10 is improved while maintaining the aesthetic balance of the left and right of the lower plate unit 13. ing.

  On the other hand, as shown in FIG. 1, the front frame set 14 above the lower plate 15 is integrally provided with an upper plate 19 as a ball receiving plate. Here, the upper plate 19 is for temporarily storing the game balls and guiding them to the game ball launching device while aligning them in a line. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame set, and an upper plate is provided on the front decorative frame, but in this embodiment, the front decorative frame is omitted. The upper plate 19 is provided directly on the front frame set 14. This is because the front frame set 14 of the present embodiment includes a window portion 101 that is largely cut out in a substantially elliptical shape so that a game area formed larger than a conventional pachinko machine can be viewed from the outside. Therefore, in order to improve the strength of the front frame set 14 as much as possible, the upper plate 19 is integrally formed with the front frame set 14. Similar to the lower plate 15, the upper plate 19 has at least a surface layer formed of a flame-retardant ABS resin. Note that how the game area is formed larger than that of a conventional pachinko machine will be described later.

  In FIG. 3, the inner frame 12 is mainly composed of a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20. A game board 30 is detachably attached to the inner frame 12 on the rear side of the resin base 20. The game board 30 is composed of a rectangular plywood and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The vertical length of the game board 30 is 476 mm, and the horizontal length is 452 mm (same size as before). That is, the game board 30 is formed in the same size as the conventional pachinko machine, and the game area is formed larger than the conventional pachinko machine.

  Next, the configuration of the game board 30 will be described with reference to FIG. In the game board 30, a general winning port 31, a variable winning device 32, a large port (starting port) 33, a small gate (through gate) 34, a variable display unit 35, etc. are arranged in a through hole formed by router processing. It is attached from the front side of the game board 30 with wood screws or the like. As is well known, when a game ball enters the general winning port 31, the variable winning device 32, and the big game port 33 and a predetermined output is output from a detection switch described later, a predetermined number is supplied to the upper plate 19 (or the lower plate 15). The prize balls will be paid out. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like are guided through the out port 36 to a ball discharge path (not shown). The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (acts) such as a windmill.

  The variable display device unit 35 includes a small symbol display device 41 that variably displays small symbols (ordinary symbols) triggered by the passage of a game ball through the small gate 34, and a big symbol symbol triggered by winning a game ball at the big mouth 33. There is provided a large symbol display device 42 as a symbol display device for variably displaying (special symbols). The accessory symbol display device 41 includes an accessory symbol display unit 43 and a holding lamp 44. Each time a game ball passes through the accessory gate 34, the display symbol (the accessory symbol) fluctuates in the display unit 43. When the variable display stops at a predetermined symbol, the big mouth 33 is configured to be activated (opened) for a predetermined time. The number of times that the game ball passes through the accessory gate 34 is held up to a maximum of four times, and the number of times of holding is displayed on the hold lamp 44. Note that the small symbol display is changed by switching the lighting of a plurality of lamps on the display unit 43 as in the present embodiment, and a part of the large symbol display device 42 (liquid crystal display device) is used. May be performed. Similarly, the hold lamp 44 may be turned on by a part of the large symbol display device 42.

  The large symbol display device 42 is composed of a liquid crystal display device, and the display content is controlled by a display control device 45 described later. The large symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are scrolled vertically for each symbol row and are variably displayed on the large symbol display device 42. In the present embodiment, the large symbol display device 42 is constituted by a large liquid crystal display of 8 inch size, and the variable display device unit 35 is provided with a center frame 47 so as to surround the large symbol display device 42. Has been.

  The variable winning device 32 includes a large winning opening formed in a horizontally long rectangular shape at the center thereof. The big winning opening is normally in a closed state where the game ball cannot be won or difficult to win, and the open state in which the game ball is likely to win in the case of a big win and the closed state in the normal state alternately Operates to repeat. Specifically, when a game ball wins the big game mouth 33, the special game is displayed on the condition that the symbols are variably displayed on the big symbol display device 42, and the final symbol after the stop is a combination of specific symbols set in advance. A condition occurs. When the special gaming state occurs, the large winning opening of the variable winning device 32 is configured to be in a state where the game ball is likely to win, that is, a predetermined open state. Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the large winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times (becomes open).

  The number of times that the game ball has passed through the big mouth 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is displayed on the hold lamp 46. The reserve lamps 46 are provided for the maximum number of reserves, and are arranged above the large symbol display device 42 in a well-balanced manner. Note that the hold lamp 46 may be deleted and turned on by a part of the large symbol display device 42.

  The game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device to the upper part of the game board 30 and is fired as the game ball launching handle 18 is rotated. The game balls are guided to the game area through the rail unit 50. The rail unit 50 is formed of a resin molded product having a ring shape, and includes an inner rail portion 51 and an outer rail mounting portion 52 that are integrally formed in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and the outer rail mounting portion 52 has a part (mainly the left side portion) facing the inner rail portion 51. Is formed. The inner rail portion 51 and the outer rail mounting portion 52 constitute a guide rail, and the inner rail portion 51 and the outer rail mounting portion 52 are parallel to each other with a predetermined interval (the left portion toward the game). A ball guide passage for guiding the ball to the game area is formed. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip of the inner rail portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide passage between the inner rail portion 51 and the outer rail attachment portion 52 to the upper portion of the game board 30 returns to the ball guide passage again.

  A return rubber 54 is attached to the outer rail mounting portion 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail mounting portion 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back with the momentum attenuated. A sliding plate 55 as a long stainless steel metal strip is attached to the inner side surface of the outer rail mounting portion 52 in order to make the flight of the game ball smoother.

  An arc-shaped flange 56 projecting outward is formed on the outer periphery of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into the plurality of through holes formed in the flange 56 and the game board 30. The rail unit 50 is fastened to 30. Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially linear shape (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50 so that the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail mounting portion 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail portion 51 to the lower end portion of the rail unit 50, and a foul ball that flows backward in the ball guide passage without reaching the game area is a foul ball passage 63 (see FIG. 3). It is to lead to. Note that the lower right corner and the lower left corner of the game board 30 are provided with adhering spaces K1, K2 for adhering seals and plates such as stamps and the like to secure the adhering spaces K1, K2. In addition, notches 58 and 59 are formed in the flange 56. As described above, since the game board 30 is provided with the adhering spaces K1, K2 such as a certificate, the game board 30 can be uniquely specified by directly attaching the certificate to the game board 30. it can. That is, it is possible to easily find an illegal exchange of game boards.

  In conventional pachinko machines, the rail is driven directly into the game board. However, as described above, in the pachinko machine 10 according to the present embodiment, the rail unit 50 is fastened to the game board 30 with screws or the like inserted through the flange 56. That is, in this embodiment, the game board 30 is formed in the same size as the conventional pachinko machine, and the game area is formed larger than the conventional pachinko machine, so the rail cannot be directly driven into the game board. The rail unit 50 is integrally formed with resin together with the flange 56, and the flange 56 is fastened to the game board 30 with screws or the like. According to the present embodiment employing such a configuration, the rail unit 50 can be easily detached from the game board 30 at the time of disposal, and therefore the rail unit 50 that is resin-molded can be easily recycled. In order to stably launch the game ball, the rail unit 50 on the game ball launch side is more firmly fixed than the other rail unit 50 with more screws. As the resin material constituting the rail unit 50, a fluorine-containing polycarbonate having a low frictional resistance is suitable.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape on the inner periphery of the rail unit 50. In particular, in the present embodiment, the game area partitioned on the board surface of the game board 30 is configured to be much larger than before. ing. In the present embodiment, the distance from the uppermost point of the outer rail mounting portion 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the inner rail portion 51 extends from the extreme left position of the outer rail mounting portion 52. The distance to the extreme right position 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 a parallel part of the inner rail part 51 and the outer rail attachment part 52 in the area surrounded by the inner rail part 51 and the outer rail attachment part 52 when viewed from the front of the pachinko machine 10. The area excluding the area of a certain guide rail. Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail mounting portion 52 but by the inner rail portion 51. Similarly, 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. Further, the upper limit position of the game area is specified by the outer rail mounting 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 desirably at least 380 mm. More preferably, it is 390 mm or more, 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. Of course, it may be 470 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. 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, 480 mm or more, and 490 mm or more. That is, the height of the game area is preferably as large as possible from the viewpoint of expanding the game area. In addition, about the combination of the said width | variety and height, it is good also as what combined the said numerical value arbitrarily.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is much larger than the conventional area ratio. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the past, so it can be said that the game area is considerably expanded on the premise that the game board 30 is shared. 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 must 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.

  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.

  The accessory gates 34 located on both sides of the variable display device unit 35 have a guide mechanism that allows the game balls that have passed through the accessory gate 34 to be moved toward the center of the game area. As a result, even in a configuration in which the game area is expanded in the left-right direction, the game ball can be guided toward the big game mouth 33 and the variable winning device 32 in the center of the game area, and as a result, the game area is expanded. It is possible to suppress a decrease in interest due to difficulty in winning a game ball. Furthermore, since the game area is expanded in the left-right direction, a windmill, a small gate 34, a plurality of nails (guide nails for guiding the game ball to the center), and other accessories can be arranged. The behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. Further, since the game area is also expanded in the vertical direction, various windmills, accessory gates 34, a plurality of nails, and other accessories can be arranged, and the behavior of the game balls in the vertical direction in the game area. Can be made even more interesting.

  Returning to FIG. In the resin base 20, a launch rail 61 for guiding a game ball immediately after being launched from the game ball launcher is attached below the window hole 21 (below the game board 30). The firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path of the rail unit 50 as described above. Is done.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded as compared with the prior art. However, under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than that of the existing one to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launching device can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 61 is formed 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.

  Further, a gap of a predetermined interval is formed between the firing rail 61 and the rail unit 50 (guide rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball fired from the game ball launching device does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate 15. Is discharged. In the case of the present embodiment, the length of the firing rail 61 is about 240 mm, and the length of the gap at the tip of the firing rail 61 (the length on the extension line of the firing rail 61) is about 40 mm.

  When the foul sphere flows backward in the guide rail, most of the foul sphere flows along the outer rail mounting portion 52 and drops downward when reaching the lower end of the outer rail mounting portion 52. May be ramped in the guide rail and jump to the inner rail 51 side. The foul ball that has jumped up hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. Therefore, it is possible to suppress interference between the foul ball and the next-launched game ball.

  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 frame set 14 side (ball outlet leading from the most downstream portion of the upper plate 19). At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large, but in the vicinity of the base end portion of the launch rail 61, its right side and Since the guide members 65 and 66 are installed on the front side, the game ball supplied from the ball outlet on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized.

  Further, the game ball launching device is provided with a hitting ball basket, and the game ball is shot with the rotation of the hitting ball bowl around the shaft portion. As this ball hitting rod is desired to be lighter, the ball hitting ball can be reduced in weight by changing the material to light metal such as aluminum and reducing the size of the shaft part, while hitting the ball to ensure sufficient firing force. A weight portion is provided in the head portion of the heel (the end portion opposite to the shaft portion). 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 hitting strength of the hitting tip can be easily adjusted.

  The discharge port 67 communicates with the upper plate 19, and the game ball is discharged (dispensed) to the upper plate 19 through the discharge port 67. An open / close shutter 68 is attached to the discharge port 67, and the shutter 68 is configured to close the discharge port 67 by an urging force of a spring or the like when the front frame set 14 is opened (the state in FIG. 3). ing. Further, when the front frame set 14 is closed, the shutter 68 is configured to be pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14. Accordingly, in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 19 is directly provided to the front frame set 14, the game balls in the payout passage and the like are spilled off when the front frame set 14 is opened. Inconvenience can be prevented.

  As shown in FIG. 3, the resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Therefore, a seal or the like stretched in the adhering space K1 at the lower right corner of the game board 30 can be viewed through the small window 71. Further, a sticker or the like can be attached from the small window 71.

  Support metal fittings 81 and 82 are attached to the left end portion of the inner frame 12 in FIG. 3 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction. Further, support metal fittings 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Accordingly, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side. Can be installed. Further, since the support hole 83 of the support fitting 81 has a notch and the lower end portion of the support fitting 151 is formed thin as shown in FIG. 5, the support fitting 151 does not have to be completely removed from the support hole 83. The front frame set 14 can be easily detached from the inner frame 12 (the pachinko machine 10) by passing the thin part of the support fitting 151 through the notch of the support hole 83.

  Next, the front frame set 14 will be described with reference to FIGS. 1 and 5. FIG. 5 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. You may form the approximate center part of this window part 101 linearly. In the present embodiment, the distance between the upper end of the window portion 101 (the uppermost portion of the outer rail mounting portion 52 and the upper end of the game area) and the upper end of the front frame set 14 (the so-called upper and lower width of the upper frame portion) is 61 mm. It is significantly shorter than the prior art with an upper frame width of about 85 mm to 95 mm. As a result, an upper area of the game area can be easily secured, and the large variable display device unit 35 can be disposed relatively upward. The distance from the upper end of the front frame set 14 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 ensured, it may be 50 mm or less.

  Further, the shortest distance between the left end of the window portion 101 and the left end of the front frame set 14 when viewed from the front of the pachinko machine 10 (the left-right width of the left side frame portion: shown on the right side in FIG. 5), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as apparent from comparison between FIGS. 1 and 3, not only the left end portion of the outer rail mounting portion 52 but also the left end portion of the inner rail portion 51 is not limited to the left side in the state where the front frame set 14 is closed. Covered by the part frame part. That is, at least a part of the guide rail overlaps and is covered with the left side frame portion of the front frame set 14 when viewed from the front of the pachinko machine 10. Even if it becomes difficult to visually recognize the game ball in this way, it is only a passing point where the game ball is guided to the game area, and it is difficult to see the game ball in the game area where the player mainly enjoys the game. It doesn't mean. Therefore, there is no trouble in actual game. Moreover, while such a trouble does not arise, sufficient intensity | strength and support strength of the front frame set 14 are securable. Incidentally, the distance in the left-right direction between the left end position of the outer rail mounting portion 52 and the left end position of the outer frame 11 when viewed from the front of the pachinko machine 10 is 21 mm, the right end position of the game area (the right end position of the inner rail portion 51) and the outside The distance in the left-right direction from the right end position of the frame 11 is 44 mm.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means change the light emission mode by turning on or blinking according to the change of the game state at the time of big hit, predetermined reach or the like, and play a role of enhancing the effect effect during the game. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks at the time of jackpot to notify that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 that also incorporates light emitting means such as LEDs. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs.

  Further, a small window 107 to which a transparent resin is attached is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102. The annular illumination part 102 is formed in a convex shape toward the front, whereas the small window 107 is formed flat. As described above, since the sticking space K1 and K2 for sticking seals and plates such as certificate stamps are provided on the back of the small window 107, the contents of the stickers and the like attached thereto are displayed on the scanner. It is flattened so that it can be optically read by a reading device. In addition, by forming the small window 107 flat, a rental ball rail of a ball lending machine (not shown) disposed between the two pachinko machines 10 does not protrude from the pachinko machine 10 to the player side. Thus, a ball lending machine can be provided.

  A lending operation unit 120 is disposed below the window unit 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. When the lending operation unit 120 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball according to the operation Is lent out. 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 supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. 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. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As shown in FIG. 5, various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, reinforcing plates 131, 132, 133, and 134 are attached to the back side of the front frame set 14 and on the upper, lower, left, and right sides of the window portion 101, respectively. 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 FIG. . The resin parts 135 prevent the metal reinforcing plates 131 to 134 from being loop-connected by the front frame set 14. When the metal reinforcing plates 131 to 134 are connected in a loop, the electromagnetic noise accompanying the launching operation of the game ball loops around the front frame set 14 disposed on the front surface of the game board 30, and the game board 30 has an adverse effect on the pachinko machine 10 and causes a malfunction, but in the pachinko machine 10 according to the present embodiment, the resin parts 135 avoid the annular connection of the metal reinforcing plates 131 to 134. The adverse effect of such noise can be suppressed. In addition, the strength reduction by using the resin part 135 for a part of the metal reinforcing plates 131 to 134 is compensated by providing the resin part 135 with a rib or increasing the thickness of the resin part 135. .

  The right reinforcing plate 131 in FIG. 5 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is a hole in the inner frame 12 with the front frame set 14 closed. It is comprised so that it may engage with the part 12a (refer FIG. 3). With this configuration, the front frame set 14 is configured to include the upper plate 19, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 can be suppressed.

  The lower reinforcing plate 134 is provided with a resin rail side wall member 136 at a position facing the firing rail 61 (see FIG. 3). The rail side wall member 136 serves as a side wall of the launch rail 61 when the front frame set 14 is closed, and functions so that game balls do not spill from the launch rail 61.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and a part of the 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, and therefore, when the front frame set 14 is closed, the pachinko machine 10 includes the inner rail portion 51 and the outer rail mounting portion 52. A part of the guide rail is configured to be covered by the front frame set 14. Therefore, in the guide rail, 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 53, the game ball spills out (jumps out) from the guide rail, and the outer rail mounting portion 52 There is a risk of being caught between the glass 137 and the like. Therefore, in the present embodiment, a rail cover 140 for covering the front side open portion of the guide rail is attached to the front frame set 14.

  The rail cover 140 is a substantially flat 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 rail, and a front frame set so as to cover a section from the proximal end portion of the guide rail to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. 14 is attached to the back side. 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. When the rail cover 140 is attached, the surface side of the rail cover 140 is in contact with the glass 137. When the front frame set 14 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide rail. Thereby, the collision of the game ball with the glass 137 can be prevented in most sections of the guide rail. Therefore, adverse effects such as breakage due to contact with the glass 137 can be suppressed.

  Further, the portion where the guide rail protrudes from the side edge portion of the glass 137 is provided at the right end portion of the rail cover 140 (that is, the portion which becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front frame set 14). A covering portion 141 for covering is provided. Thereby, it is possible to prevent the occurrence of problems such that the game ball spills out of the guide rail (jumps out) or gets caught between the outer rail mounting portion 52 and the glass 137.

  Further, the rail cover 140 is formed with a ridge 142 extending in an arc shape along the inner edge thereof and projecting toward the front side of FIG. When the front frame set 14 is closed, the protrusion 142 is configured to overlap the inner rail portion 51 substantially integrally with the protrusion 142 entering the guide rail. Therefore, for example, even if a wire or the like is invaded through the gap between the front frame set 14 and the inner frame 12 to perform a fraudulent act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. The protrusion 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 or the like to enter in a wider range, and it is possible to more surely prevent an illegal act performed using the wire or the like.

  Next, the configuration of the back surface of the pachinko machine 10 will be described in detail with reference to FIGS.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. Various control boards are arranged on the back of the pachinko machine 10 (actually on the back of the inner frame 12 and the game board 30) so as to be arranged vertically and horizontally, or stacked one after another. A game ball supply device (payout mechanism) for supplying a ball, a protective cover made of resin, and the like are attached. In this embodiment, various control boards are divided into two mounting bases to form two control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. ing. In this case, the main board and the sound lamp control board are mounted on one mounting base to form a unit, and the dispensing control board, launch control board, and power supply board are mounted on the other mounting base to form a unit. Here, for convenience, the former unit is referred to as a “first control board unit 201” and the latter unit is referred to as a “second control board unit 202”. In addition, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203”. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units. It is configured to be openable and closable with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  Actually, as shown in the schematic diagram of FIG. 8, the units 201 to 203 are arranged side by side and attached. In FIG. 8, the first control board unit 201 having a substantially L shape is arranged in the approximate center of the pachinko machine 10, and the second control board unit 202 is arranged below the first control board unit 201.

The back pack unit 203 is fixedly held to the main body of the pachinko machine 10 by these fastening portions M7 and the locking portions M8, M9.

  The development directions of the units 201 to 203 are not the same, and the first control board unit 201 opens left when viewed from the back of the pachinko machine 10, whereas the second control board unit 202 and the back pack unit 203 are It is configured to open on the right.

  On the other hand, FIG. 9 is a rear view showing a state in which the game board 30 is assembled to the inner frame 12. FIG. 10 is a perspective view of the inner frame 12 as viewed from the rear, and FIG. 11 is a perspective view of the game board 30 as viewed from the rear. Here, the backside structure of the inner frame 12 and the game board 30 will be described with reference to FIGS.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 20 and is not dropped by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated, and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a state where the locking fixtures 211 and 212 are in the locked position. The locking fixtures 211 at the three left and right sides of the game board 30 are configured by L-shaped metal fittings formed by bending metal pieces, and are configured so as not to protrude outward from the inner frame 12 when the game board 30 is fixed. ing. The locking fixture 212 at one lower portion of the game board 30 is formed of a resin I-type fastener.

  A variable display device unit 35 is arranged in the center of the game board 30. In the variable display device unit 35, a frame cover 213 made of resin (for example, made of ABS) that covers the center frame 47 (see FIG. 4) from behind is provided to protrude rearward, and at the rear end of the frame cover 213, A large symbol display device 42 as a liquid crystal display device and a display control device 45 are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 are disposed.

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, it corresponds to the opening portion of the game board 30 of the general prize opening 31, the variable prize winning device 32, and the big prize opening 33 (see FIG. 4 respectively) described above, and at one place on the downstream side. A collecting passage 216 is formed. Also, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is attached below the game board 30, and the discharge passage board 217 is used for guiding the discharge ball to the outside of the pachinko machine 10. A discharge passage 218 is formed. Therefore, as illustrated in phantom lines in FIG. 9, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further, the discharge passage 218 of the discharge passage board 217 is formed. Through the pachinko machine 10. Similarly, the out port 36 (see FIG. 3) communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

  In the above configuration, with the lower end surface of the game board 30 as a boundary, a back frame set 215 (collection passage 216) is provided on the upper side, and a discharge passage board 217 (discharge passage 218) is provided on the lower side. The game board 30 is provided without overlapping (overlapping) in the front-rear direction. Therefore, when the game board 30 is removed from the inner frame 12, there is no inconvenience that the discharge passage board 217 prevents the game board 30 from being removed.

  In addition, since the discharge passage board 217 is provided just behind the upper plate 19 on the front surface of the pachinko machine 10, a wire or the like is inserted from the ball discharge port (the ball passage rod 69 in FIG. 2) leading to the upper plate 19, Further, an illegal act of causing the wire or the like to enter the game area side through a gap between the inner frame 12 and the discharge passage board 217 can be considered. Therefore, in the pachinko machine 10, a plate 219 that extends in front of the pachinko machine 10 so as to almost integrally overlap the inner frame 12 is provided just behind the upper plate 19 of the discharge passage board 217. Therefore, even if a wire or the like tries to enter from the gap between the inner frame 12 and the discharge passage board 217, the wire or the like is obstructed by the plate 219, and it becomes very difficult to make the wire or the like enter the game area. As a result, it is possible to prevent an illegal act such as forcibly opening the variable winning device 32 (large winning opening) using a wire or the like.

  In addition, on the back side of the game board 30, a winning detection mechanism and the like for detecting the passage of the game ball to various winning holes and the like are provided. Specifically, a prize opening switch 221 is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and a specific area switch 222 and a count switch 223 are provided in the variable prize winning device 32. The specific area switch 222 is a switch for determining that a game ball won in the variable winning device 32 in the big hit state has entered a specific area (an area for determining whether or not to continue the big hit state), and the count switch 223 displays the winning ball. It is a switch to count. In addition, an operating port switch 224 is provided at a position corresponding to the large port 33, and a gate switch 225 is provided at a position corresponding to the small gate 34.

  The prize opening switch 221 and the gate switch 225 are connected to the board relay board 226 through electric wiring (not shown), and this board relay board 226 is further connected to a main board (main control device 261) described later. Further, the specific area switch 222 and the count switch 223 are connected to the special winning opening relay board 227, and the special winning opening relay board 227 is also connected to the main board. On the other hand, the operation port switch 224 is directly connected to the main controller 261 without using a relay board.

  Although not shown in the drawings, the variable winning device 32 is provided with a large winning opening solenoid for opening the large winning opening and a winning ball sorting plate solenoid for guiding the winning ball to a specific area. Is provided with an operating port solenoid for opening the electric accessory. In FIG. 9, a set handle 228 having a hitting ball basket or the like is disposed on the lower left side of the back surface of the pachinko machine 10, and a firing motor 229 is disposed on the left side thereof.

  The detection results detected by the winning detection mechanism are taken into a main board, which will be described later, and a payout command (the number of game balls to be paid out) corresponding to the winning situation is transmitted from the main board to the payout control board. The Then, a predetermined number of game balls are paid out by the output of the payout control board. In such a case, a conventional method (so-called evidence ball method) in which game balls won at various winning openings are once collected in a winning ball processing device, and the winning ball processing device confirms the presence of the winning balls one by one and then pays out one by one. Unlike the above, the pachinko machine 10 according to the present embodiment electrically senses the winning of a game ball for each winning opening and immediately pays out (that is, the pachinko machine 10 abolishes the winning ball processing device). is doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly.

  The back frame set 215 is provided with an attachment mechanism for attaching the first control board unit 201. Specifically, as shown in FIG. 11, as the attachment mechanism, a support fitting 231 extending in the vertical direction is provided at the lower left corner when viewed from the back of the game board 30, and the support fitting 231 is on the same axis. A pair of upper and lower support holes 231a are formed.

Below the tank 355, for example, a tank rail 356 that has two rows (two rows) of spherical passages and is gently inclined toward the downstream side is connected. A case rail 357 is connected. The payout device 358 is provided in the most downstream portion of the case rail 357, and a required number of game balls are paid out appropriately according to a predetermined electrical configuration such as a payout motor 358a. The game balls paid out from the payout device 358 are supplied to the upper plate 19 through the payout passage 359 and the like shown in FIG.

  A vibrator 360 for applying vibration to the tank rail 356 is attached to the tank rail 356. Therefore, if a ball clogging occurs near the tank rail 356, the ball clogging can be eliminated by driving the vibrator 360. Since this vibrator 360 is unitized, it can be easily attached to the tank rail 356.

  Here, the configuration of the tank rail 356 will be described in detail with reference to FIG. FIG. 22 is an exploded perspective view of the tank rail 356. The tank rail 356 has a rail body 361 having an elongated bowl shape opened upward, and a spherical ball receiving portion 362 is provided at the start end of the rail body 361. By this ball receiving portion 362, the game ball that has dropped from the tank 355 is smoothly taken into the rail body 361. In addition, the rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. One or two ridges 364 are provided on the bottom surface of each spherical passage partitioned by the partition wall 363, and an opening 365 is provided on the side of the ridge 364.

  In addition, a rectifying plate 367 is disposed on the rail body 361 so as to cover the ceiling portion of the downstream half. The rectifying plate 367 has a bowed shape so as to limit the height of the ball passage in the tank rail 356 toward the downstream side, and a convex portion 368 extending in the longitudinal direction is formed on the lower surface thereof. . Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even when a large amount of game balls flow into the tank rail 356, the game balls are prevented from being caught, and the ball clogging in the tank rail 356 is eliminated. The rail body 361 is formed of a black conductive polycarbonate resin, whereas the rectifying plate 367 is formed of a transparent polycarbonate resin.

Thereby, generation | occurrence | production of the noise by charging of a game ball is suppressed.

  Further, the back pack 351 is provided with a pair of upper and lower support shafts 385 at the right end portion in FIG. 20 and the like. By inserting the support shafts 385 into the support hole portion 238 shown in FIG. The pack unit 203 is supported so as to be openable and closable with respect to the inner frame 12. In addition, the back pack 351 is provided with a pair of upper and lower nai latches 386 as fasteners at the left end portion, and a locking hole 387 is provided at the upper end portion. The nai latch 386 is inserted into the tightened hole 240 shown in FIG. The back pack unit 203 is fixed to the inner frame 12 so that it cannot be opened and closed by engaging the fixing hole 387 shown in FIG. The reason why the ny latch is not used for the fixing tool 242 and the locking hole 387 is that a tank 355 for storing game balls is provided on the left side of the locking hole 387 in FIG. is there. When the fixture 242 is fixed, the back pack unit 203 is also fixed to the inner frame 12 by the fixtures 241 and 243 shown in FIG. The support hole 238 and the support shaft 385 are in the support shaft portion M6 in FIG. 8, the fastened hole 240 and the ny latch 386 are in the fastening portion M7, and the fixture 242 and the lock hole 387 are in the lock portion M8, respectively. Equivalent to. Further, the fixture 243 corresponds to the locking portion M9.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. The main controller 261 is equipped with an MPU 501 as a one-chip microcomputer that is an arithmetic unit. The MPU 501 includes a program ROM 502 (hereinafter simply abbreviated as “ROM”) that stores various control programs executed by the MPU 501 and fixed value data, and various data when executing the control program stored in the ROM 502. RAM 503 that is a memory for temporarily storing the ID, ROM 506 that is provided separately from ROM 502 and that stores a unique identification number set for each pachinko machine 10, and generates a random value A random number generation circuit 507 and other various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit (not shown) are incorporated.

  The RAM 503 is configured to retain (backup) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is powered off. The RAM 503 temporarily stores various data and the like. In addition to the memory and area for this purpose, a backup area 503a is provided.

  The backup area 503a stores values such as a stack pointer, each register, and I / O when the power is shut down (including when a power failure occurs, the same applies hereinafter) when the power is shut down due to the occurrence of a power failure or the like. When the power is turned on (including power-on due to power failure cancellation, the same applies hereinafter), the state of the pachinko machine 10 is restored to the state before power-off based on the information in the backup area 503a. Writing to the backup area 503a is executed when the power is shut off by the NMI interrupt process (see FIG. 34), and restoration of each value written to the backup area 503a is executed in the main process (see FIG. 26) when the power is turned on. . Note that the power failure signal SG1 from the power failure monitoring circuit 542 is input to the NMI terminal (non-maskable interrupt terminal) of the MPU 501 when the power is shut down due to the occurrence of a power failure or the like, and the power failure signal SG1 is the MPU 501. Is input immediately, the NMI interrupt process as a power failure process is immediately executed.

  The weight memory 503b is a normal process for controlling a game including a lottery for winning a prize to the big mouth 33 in a weight process (see S102 in FIG. 26) that is performed once every time the game machine is started up. This is for measuring the time to wait for the transition to (see FIG. 28). When the main process is started, “500” is written in the wait memory 503b, and thereafter “1” is subtracted by “1” every 2 milliseconds (hereinafter, “millisecond” is expressed by “ms”). During the period in which the value of the wait memory 503b is “1” or more, the progress of the process toward the normal process is awaited, the progress of the process is stopped, and the start of the normal process is delayed by the waiting time. When the value of the wait memory 503b becomes “0”, the standby state is canceled and the processing proceeds to the subsequent processing.

  Here, the main process of the MPU 501 is a normal process (see FIG. 28) to be described later in which a certain process is repeatedly performed to control a game, and a process performed before the start of the normal process. Or processing (start-up processing) such as preparing for a return to the state before power-off. The activation process is started when power is turned on or a reset signal is input to a reset terminal (not shown). Among the processes, a stack pointer, registers, I / O, and the like necessary for proceeding with the process are first included. The system is set up so that the system can be operated. This start-up is performed in other control devices other than the MPU 501 of the main control device 261. However, a control device (for example, the display control device 45) having a high load processing or a large RAM has a longer time to start up. A control device that requires and has little processing starts up in a short time. However, in order to control the game normally, it is preferable to start after each control device is up and ready for various processes such as command exchange. For example, when the main control device 261 starts up before the payout control device 311 starts up, even if a command is transmitted from the main control device 261 to the payout control device 311, the payout control device 311 cannot properly accept the command. There is a risk of malfunction.

  In the pachinko machine 10 of the present embodiment, the main control device 261 (MPU 501) starts up earlier than the payout control device 311 (MPU 511). For this reason, when the power is turned on or a reset signal is input, the main process of the main controller 261 is a wait process (see FIG. 26, S102) after starting up in the initial setting process (see FIG. 26, S101). ) And wait for the payout control device 311 to rise. In this embodiment, the time difference until the payout control device 311 starts up behind the main control device 261 is about 0.8 seconds and is always less than 1 second. At least in the wait process (S102) by the main control device 261, After waiting for 1 second, the process of the main controller 261 is advanced. Thereby, the game control by the main controller 261 and the payout controller 311 can be appropriately performed. Note that the standby time is preferably set to the maximum including the variation of the time differences according to the time differences of a plurality of control devices that need to be controlled synchronously. The numerical value of time is not limited.

  The ID ROM 506 is a ROM for storing a unique identification number set for each pachinko machine 10, and a unique code memory 506a to which 8 bytes are allocated is provided as a storage area. In the unique code memory 506a, a value (unique information) as an identification number unique to the MPU 501 (that is, unique to the pachinko machine 10) is written. The value of the unique code memory 506a plays a role as security information of the pachinko machine 10, and is configured with a unique number that is different for each MPU.

  The MPU 501 is provided with an inspection port (not shown) (not shown), and a modular jack (not shown) is connected to the end. When a checker (not shown) is connected to the MPU 501 via this modular jack, the value of the unique code memory 506a can be read from the outside, and a security check for verifying the authenticity of the MPU 501 can be performed. For this reason, it is possible to detect an illegal act of illegally rewriting the value or the like of the unique code memory 64a or exchanging the MPU 501 with an illegal MPU, making it difficult to execute the illegal act. Note that it is not always necessary to configure the checker to be connected to the modular jack, and the MPU identification number may be verified by a checker that can be verified wirelessly.

  The value of this unique code memory 506a is read in a wait process (see S102 in FIG. 26) that is performed once each time the startup is performed, and waits before the normal process is started by the wait process (S102). Used to determine time. As described above, since the value of the unique code memory 64a is composed of a unique number that is different for each pachinko machine, the normal process is started from the start of the main process determined using the value of the unique code memory 64a. The time interval until the start is different for each pachinko machine, and as a result, the value of the jackpot random number counter C1 after a predetermined time has elapsed from the start of the main process is different for each pachinko machine to suppress fraud. be able to. The ID ROM 506 is provided with a memory (not shown) for storing the manufacturer code, model code, and the like of the pachinko machine 10 in addition to the unique code memory 506a.

  The random number generation circuit 507 is a circuit configured to generate random values from 1 to a predetermined maximum value. The random number generation circuit 507 is configured such that a random number value equal to or less than the value set as the maximum value does not overlap at all in one cycle (the number of times set as the maximum value and a period until the random value is acquired), and Generate in an irregular order.

  The random number value generated by the random number generation circuit 507 is acquired by a program controlled by the MPU 501. Specifically, by writing “1” to a random number update register (not shown) in the MPU 501, the random number value in the random number generation circuit 507 is updated, and the updated random number value is stored in the random number value register (in the MPU 501). (Not shown) and “0” is set in the random number update register. The program of the MPU 501 reads the value of the random number update register and acquires the random value.

  The random number generation circuit 507 can update the random number value by a plurality of types of update methods, and the setting for the update method is the initial setting of the random number generation circuit described later (see FIG. 27, S125). Done in. Further, various known configurations can be used for the random number generation circuit 507, and the description thereof is omitted.

  An input / output port 505 is connected to the MPU 501 of the main control device 261 via a bus line 504 including an address bus and a data bus. The input / output port 505 is connected to a RAM erasing switch circuit 543, a payout control device 311, a display control device 45, and other switches not shown.

  The payout control device 311 controls payout of prize balls and rental balls by a payout motor 358a. The MPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the MPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

  The RAM 513 of the payout control device 311 is configured to hold (backup) data by supplying a backup voltage from the power supply device 313 even after the power of the pachinko machine 10 is shut off, like the RAM 503 of the main control device 261. The RAM 513 is provided with a backup area 513a in addition to a memory and an area for temporarily storing various data.

  The backup area 513a is an area for storing the stack pointer, each register, I / O, and the like when the power is shut down when the power is shut down due to a power failure or the like. Based on the information in the backup area 513a, the state of the pachinko machine 10 is restored to the state before the power is shut off. Writing to the backup area 513a is executed when the power is shut off by the NMI interrupt process, and restoration of each value written to the backup area 513a is executed in the main process when the power is turned on. As with the MPU 501 of the main controller 261, the power failure signal SG1 is also input to the NMI terminal of the MPU 511 from the power failure monitoring circuit 542 when the power is interrupted due to the occurrence of a power failure or the like. When input to the MPU 511, an NMI interrupt process as a power failure process is immediately executed.

  An input / output port 515 is connected to the MPU 511 of the payout control device 311 via a bus line 514 including an address bus and a data bus. A RAM erase switch circuit 543, a main control device 261, a firing control device 312, a payout motor 358a, and the like are connected to the input / output port 515, respectively.

  The launch control device 312 permits or prohibits the launch of the game ball by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. Specifically, the launch control signal is output from the payout control device 311, the player is detecting that the player is touching the game ball launch handle 18, and the launch for stopping the launch. On condition that the stop switch is not operated, the launch motor 229 is driven, and the game ball is launched with a strength corresponding to the operation amount of the game ball launch handle 18.

  The display control device 45 controls the small symbol (ordinary symbol) variation display on the small symbol display device 41 and the large symbol symbol (special symbol) variation display on the large symbol display device 42. The display control device 45 includes an MPU 521, a ROM (program ROM) 522, a work RAM 523, a video RAM 524, a character ROM 525, an image controller 526, an input port 527, two output ports 528 and 529, and a bus line. 530 and 531. The input side of the input port 527 is connected to the output side of the main controller 261, and the output side of the input port 527 is connected to the MPU 521, ROM 522, work RAM 523, and image controller 526, and output port via the bus line 530. 528 is connected. The accessory symbol display device 41 and the sound lamp control device 262 are connected to the output side of the output port 528. Further, an output port 529 is connected to the image controller 526 via a bus line 531, and a large symbol display device 42 is connected to the output side of the output port 529.

  The MPU 521 of the display control device 45 controls the display of the small symbol display device 41 and the large symbol display device 42 based on the symbol display command transmitted from the main control device 261. The ROM 522 is a memory for storing various control programs executed by the MPU 521 and fixed value data, and the work RAM 523 is for temporarily storing work data and flags used when the MPU 521 executes various programs. Memory.

  The video RAM 524 is a memory for storing display data displayed on the large symbol display device 42, and the display content of the large symbol display device 42 is changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as symbols displayed on the large symbol display device 42. The image controller 526 adjusts the timings of the MPU 521, the video RAM 524, and the output port 529 to intervene in reading and writing data, and also reads display data stored in the video RAM 524 from the character ROM 525 at a predetermined timing. It is displayed on the display device 42.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch circuit 543 having a RAM erase switch 323. ing. The power supply unit 541 supplies necessary operating voltages to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in a voltage of 24 volts AC supplied from the outside, drives a switch, a motor, etc., has a voltage of 12 volts, a voltage of 5 volts for logic, and a RAM backup. A backup voltage or the like is generated, and the 12 volt voltage, the 5 volt voltage, and the backup voltage are supplied to the main controller 261, the payout controller 311, and the like. The firing control device 312 is supplied with operating voltages (12 volts and 5 volts) via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the MPU 501 of the main control device 261 and the MPU 511 of the payout control device 311 when the power is interrupted due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541. When this voltage becomes less than 22 volts, it is determined that a power failure (power shutdown) occurs. The power failure signal SG1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SG1, the main controller 261 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. The power supply unit 541 outputs a voltage of 5 volts, which is the drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Is maintained at a normal value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the NMI interrupt processing.

  The RAM erase switch circuit 543 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main controller 261 and the payout controller 311 when the RAM erase switch 323 is pressed. When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main controller 261 and the payout controller 311 clear the data in the respective backup areas 503a and 513a.

  Here, with reference to FIG. 24, the display content of the large symbol display apparatus 42 is demonstrated. The large symbol display device 42 displays three symbol rows of left, middle, and right. Each symbol sequence is composed of, for example, a main symbol with numbers “0” to “9”, and a sub-symbol made of, for example, a rhombus-shaped symbol. It is composed. In each symbol row, main symbols are arranged in ascending or descending numerical order, and sub-designs are arranged between the main symbols. That is, each symbol row is provided with a total of 20 large symbols of 10 main symbols and 10 sub symbols, and 20 large symbols scroll periodically from top to bottom for each symbol row. It is displayed in a variable manner. In particular, the numbers of the main symbols are arranged so that they 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 large symbol display device 42 displays large symbols in three stages, upper, middle, and lower for each symbol row. Accordingly, the large symbol display device 42 displays a total of nine large symbols in 3 rows × 3 columns. The large symbol display device 42 has five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5. Then, the variable display stops in the order of 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) A big hit video will be displayed as a big hit if it is aligned.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to perform a jackpot lottery, setting a symbol display of the big symbol symbol display device 42, and the like. 25, 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 big game symbol display device 42, and the reach lottery when the big symbol symbol display device 42 fluctuates. Reach random number counter C3 used for setting, initial value setting for initial value of jackpot random number counter C1, random number initial value counter CINI used for variation pattern selection of large symbol display device 42, variation type counters CS1, CS2, left column, The left, middle, and right out symbol counters CL, CM, and CR used to set each out symbol in the middle and right columns It is set to be there. A small symbol random number counter C4 is used for the lottery of the small symbol display device 41.

  Among these counters, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. The out symbol counters CL, CM, CR are configured such that the register values are added using the R register (refresh register) in the MPU 501, and as a result, the 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), and in each of these areas, game balls to the big game mouth 33 are provided. Each value of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 is stored in accordance with the winning timing.

  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 configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once every timer interruption and within the remaining time of normal processing. Will be updated repeatedly. The big hit random number counter C1 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 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 values are “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”. High probability means a state in which the combination of large symbols becomes a big hit by a predetermined combination of probability fluctuation symbols and the subsequent jackpot probability is increased as added value, so-called probable change, and normal (low probability) (Time) means a time when such a state of probability is not met.

  The jackpot symbol counter C2 determines a symbol when the fluctuation of the large symbol display device 42 is stopped in the case of a jackpot. In the present embodiment, the large symbol symbol display device 42 has five effective lines, and a specific symbol is selected. Since 10 types of (main symbols) are set, 50 (0 to 49) counter values are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 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 out” and stop “complete out” that does not occur reach. For example, the reach random number counter C3 = 0, 1 corresponds to the front / rear out of reach, the reach random number counter C3 = 2-21 corresponds to the reach other than the front / rear out, and the reach random number counter C3 = 22-238 corresponds to the complete out. Note that the reach lottery may be set individually according to the lottery probability state of the large symbol display device 42, 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 big game mouth 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. The other variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0. 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 a large symbol such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (book) In the embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by the combination of the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the variation of the large symbol is started by the large symbol display device 42.

  The left, middle and right off symbol counters CL, CM, and CR are used to determine the left column large symbol symbol, middle column large symbol symbol, and right column large symbol symbol when the big hit lottery is off. Yes, in each column, any of the 20 large symbols including the main symbol and the sub symbol is displayed, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle, and lower symbols are determined by the out symbol counter CL, the upper, middle, and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The upper, middle and lower symbols are determined.

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

  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.

  The accessory symbol random number counter C4 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The accessory symbol random number counter C4 is periodically updated (once every timer interruption in this embodiment), and is acquired when it is detected that the game ball has passed through the accessory gate (through gate) 34 on either the left or right side. Is done. 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 MPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. The processing of the MPU 501 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 ms), and a power failure signal SG1 to the NMI terminal. There is an NMI interrupt process activated by input. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 32 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 501 of the main controller 261 every 2 ms, for example. In the timer interruption process, first, reading processes of various winning switches are executed (S601). That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI is updated (S602). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in 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.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are updated (S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). 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. After that, a start winning process is performed in accordance with winning in the big mouth 33 (S604).

  This start winning process will be described with reference to the flowchart of FIG. First, it is determined from the detection information of the operation port switch 224 whether or not the game ball has won a prize (start prize) at the big mouth 33 (S701). When it is determined that the game ball has won the big game mouth 33 (S701: Yes), it is determined whether or not the number N of active reserved balls of the big game symbol display device 42 is less than the upper limit value (4 in the present embodiment). (S702). If there is a prize at the big mouth 33 and the number N of activated balls is less than 4 (S702: Yes), the number N of activated balls is incremented by 1 (S703), and the jackpot random number counter updated in step S603 is further added. Each value of C1, jackpot symbol counter C2 and reach random number counter C3 is stored in the first area among the empty reserved areas of the reserved ball storage area of RAM 503 (S704). On the other hand, if there is no winning at the big mouth 33 (S701: No), or even if there is a winning at the big mouth 33, if the operation holding ball number N <4 (S702: No), each of S703 and S704 The process is skipped and the start winning process is terminated. After the start winning process is completed, the MPU 501 once ends this timer interrupt process.

  When the game ball wins the big game mouth 33 (start prize), the big game symbol display device 42 starts to display the fluctuation of the big game symbol. After the winning prize, the big game symbol changes and the symbol stops. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before reaching. Therefore, in the start winning process, when the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (S704). Specifically, since the start winning process is executed at a cycle of 2 ms, 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 a large symbol variation pattern, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses).

  FIG. 34 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 501 of the main controller 261 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 process, the state of the main controller 261 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, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the MPU 501 in the main controller 261, and the MPU 501 interrupts the control being executed. NMI interrupt processing is started. The NMI interrupt processing program of FIG. 34 is stored in the ROM 502 of the main controller 261. 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 control device 261 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt process, first, the used register is saved in the backup area 503a of the RAM 503 (S801), and the value of the stack pointer is stored in the backup area 503a (S802). Further, the occurrence information of the power shutdown is set in the backup area 503a (S803), and a power shutdown notification command indicating that the power is shut off is transmitted to another control device (S804). A RAM determination value is calculated and stored in the backup area 503a (S805). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. After that, access to the RAM 503 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and processing cannot be executed.

  The above NMI interrupt process is executed in the same manner by the payout control apparatus 311. With this NMI interrupt process, the state of the payout control apparatus 311 at the time of power interruption due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513 Is done. 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 MPU 511 in the payout controller 311 and the MPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 34 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 26 is a flowchart showing a main process executed by the MPU 501 in the main controller 261. This main process is started by a reset at power-on. In the main process, first, the system is started up by executing an initial setting process associated with power-on (S101). Specifically, a predetermined value set in advance in the stack pointer, the state of each circuit in the MPU 501 is set, and access to the RAM 503 is permitted. Next, wait processing is executed to wait for the sub-side control device (such as the payout control device 311) operating based on the command from the main control device 261 to become operable (S102), and then payout is performed. A payout permission command is transmitted to the control device 311. This wait process (S102) is also a process for preventing an illegal act of illegally generating a jackpot by inputting an illegal signal, and details of the process will be described later with reference to FIG.

  After the process of S103, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is turned on (S104). If the RAM erase switch 323 is turned on (S104: Yes), the backup data should be cleared (erased). The process proceeds to S114. On the other hand, if the RAM erasure switch 323 is not turned on (S104: No), it is further determined whether or not the information on occurrence of power interruption is stored in the backup area 503a of the RAM 503 (S105). (S105: No), since backup data is not stored, in this case as well, the process proceeds to S114. If the power-off occurrence information is stored in the backup area 503a (S105: Yes), the RAM determination value is calculated (S106), and the calculated RAM determination value is not normal (S107: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S114. As described above, the RAM determination value is a checksum value at a work area address of the RAM 503, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 503 is 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 RAM initialization processing (S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (S114 to S116) of the RAM 503. That is, in the RAM initialization process from S114, the used area of the RAM 503 is cleared to 0 (S114), and the initial value of the RAM 503 is set (S115). The initial value is set to “0” in the jackpot random number counter C1 that stores the value of the random number used for the jackpot lottery. Thereafter, the interruption is permitted (S116), and the process proceeds to normal processing described later.

  On the other hand, if the RAM erasure switch 323 is not turned on (S104: No), the information on the occurrence of power shutdown is stored (S105: Yes), and the RAM judgment value (checksum value etc.) is normal ( (S107: Yes), the process proceeds to S108, and the process at the time of power recovery (process at the time of power-off recovery) is executed. That is, in the power recovery process, the stack pointer at the time of power interruption is restored (S108), and the information on occurrence of power interruption is cleared (S109). Next, a power-return command for returning the sub-side control device to the gaming state at the time of power-off is transmitted (S110), and the used register is returned from the backup area 503a of the RAM 503 (S111). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S112). If the interrupt is permitted (S112: Yes), the interrupt is permitted (S113). On the other hand, the interrupt is prohibited when the power is turned off. If it is in the state (S112: No), the processing is returned to the address before the power is shut off while the interruption is prohibited. When returning to the address before power-off, the processing returns to the processing at the time of power-off in normal processing described later, and the processing is continued from the state at the time of power-off.

  Next, the wait process (S102) performed in the main process will be described with reference to FIG. FIG. 27 is a flowchart showing the wait process (S102). This process is a process for waiting for the sub-side control device to be in an operable state and preventing an illegal act of illegally generating a jackpot by inputting an illegal signal.

  First, “500” is written to the wait memory 503b (S121), and it is determined whether or not the value of the wait memory 503b is “1” or more (S122). If the value is “1” or more, the value of the wait memory 503b is decremented by “1” (S123), and it is determined whether or not a predetermined time (2 ms in the present embodiment) has elapsed since the start of the previous processing of S122. Judgment is made (S124). If 2 ms has not elapsed (S124: No), the process of S124 is repeated.

  On the other hand, if 2 ms has elapsed (S124: Yes), the process proceeds to S122, and the processes after S122 are repeated. The process of S122 is performed every 2 ms, and the value of the wait memory 503b is subtracted by “1” every 2 ms. When the process of S123 is repeated 500 times, the value of the wait memory 503b is determined to be “0” in the process of S122 (S122: No), and the process proceeds to the processes after S125. The processing from S122 to S124 is performed for 1 second obtained by multiplying 2 ms by 500, and during this time, the progress of the main processing is awaited. The standby time difference between the main control device 261 and the sub control device is adjusted.

  In the process of S125, initial setting of the random number generation circuit 507 is performed, such as setting “256” as the maximum value of the random number or setting the start value for the second and subsequent times (S125). In accordance with this setting, the random number generation circuit 507 generates a random value so as not to overlap in one cycle within the range of “1” to “256”. Therefore, by reading the value 256 times from the random number generation circuit 507, all values in the range of “1” to “256” are read.

  In the processing after S126, the value of the random number generation circuit 507 is read (S126), and it is determined whether the read value is the same as the value of the lower 8 bits of the specific code memory 506a (S127). Here, in the processing of S127, when the value read by the random number generation circuit 507 is “256”, it is determined that “0” that is the value of the lower 8 bits is the read value.

  If the value read in the process of S127 is the same as the lower 8 bits of the unique code memory 506a (S127: Yes), the wait process (S102) is terminated and the process returns to the main process of FIG. Progress the process toward. On the other hand, if the value read in the process of S127 is not the same as the lower 8 bits of the unique code memory 506a (S127: No), the process proceeds to the normal process. That is, it is determined whether or not a predetermined time (2 ms in the present embodiment) has elapsed since the start of the previous processing of S126 (S128). If 2 ms has not elapsed (S128: No), the processing of S128 is performed. Repeatedly, the process proceeds to S126 at the timing when 2 ms have passed. For this reason, the processing of S126 and S127 is repeatedly performed every 2 ms.

  Further, while the value of the lower 8 bits of the unique code memory 506a is a fixed value, the value generated by the random number generation circuit 507 changes every time the main process is started, and the value read in the process of S127 is The number of times that the processing of S126 and S127 is performed until it becomes the same as the lower 8 bits of the unique code memory 506a varies within a range from a minimum of 1 to a maximum of 256. Since the time of 2 ms elapses when the processing of S126 and S127 is repeated once, the time required from the first processing of S126 to being judged “Yes” in the processing of S127 is 256 in 2 ms. It fluctuates within the range of about 0.5 seconds multiplied.

  Here, for example, an illegal board (a so-called “hanging board” or the like) is attached between the main control device 261 and the power supply device 313, and a signal illegally generated from the board (for example, a power failure signal SG1) is generated. An illegal act to be output to the main control device 261 can be considered. For example, if the improperly generated power failure signal SG1 is continuously output to the main controller 261 and the NMI interrupt process (see FIG. 33) performed when the power is shut off frequently occurs, the main controller 261 (MPU 501) The process cannot be executed normally, and the previous state is initialized (RAM 503 is initialized). Thereby, the update of the big hit random number counter C1 can be started from a fixed value such as “0”, and the value of the big hit random number counter C1 corresponds to the big hit after a certain time. A person who performs an illegal act (unauthorized board) further illegally generates a detection signal of the operating port switch 224 for detecting a prize to the big mouth 33, and outputs the detection signal generated illegally at a jackpot timing. It will generate a jackpot illegally.

  However, according to the pachinko machine 10 of the present embodiment, after the power failure signal SG1 is input and the main processing is started, the value of the jackpot random number counter C1 is a value corresponding to the jackpot (a jackpot value) “337” and The wait process (S102) is performed until “673” is reached, and the time during which the progress of the process is awaited by the processes of S126 to S128 varies within a range of about 0.5 seconds. Since the value of the jackpot random number counter C1 is updated by 1 every 2 ms, the random number value fluctuates within a range of about 250 with respect to the fluctuation of about 0.5 seconds. Therefore, even if an attempt is made to output an illegally generated detection signal at the jackpot timing, the timing at which the updating of the jackpot random number counter C1 cannot be grasped, and the jackpot cannot be illegally generated. Accordingly, it is possible to prevent an illegal act such as unjustly generating a big hit by a so-called “hanging board” or the like.

  Further, the state (waiting state) in which the processing for normal processing in which the big hit random number counter C1 is subsequently updated is waited by the processing of S126 to S128 of the wait processing (S102) (standby state) is stored in the specific code memory 506a. The process continues until the condition corresponding to the value is established and the process proceeds to S127. The conditions correspond to the pachinko machine-specific identification numbers set differently for each pachinko machine, so the duration of the standby state for the plurality of pachinko machines 10 is different for each pachinko machine. The time interval from the start-up (start of the main process) until the value of the jackpot random number counter C1 is updated to the jackpot value is different for each pachinko machine. For this reason, since the elapsed time from turning on the power to the jackpot random number counter C1 reaching the jackpot value differs for each pachinko machine, even pachinko machines of the same model are different in order to perform fraud. An illegal board with specifications is required. Accordingly, it is possible to make it difficult to manufacture an illegal substrate and reduce illegal acts using the illegal substrate.

  The standby state in which the process from S126 to S128 waits for the normal process is performed in advance in the pachinko machine in which the value acquired from the random number generation circuit 507 by the process of S126 is based on the value of the unique code memory 506a. It is canceled when the set value (special value) is reached. Since the number of acquisitions of the value until the value read (acquired) by the processing of S126 becomes the special value is different for each start-up and for each pachinko machine, the duration of the standby state is Each start-up time and each pachinko machine will be different, and the time interval from the start-up to the start of normal processing will be irregular. For this reason, the time interval between the start-up and the timing at which the value of the jackpot random number counter C1 becomes the jackpot value becomes irregular, and the fraudulent act using an illegal board that inputs an illegal signal after a lapse of a certain time from the start-up. Can be prevented.

  Further, when it is determined that the value read by the process of S126 is not a special value by the process of S127, the time interval from the previous acquisition of the value to the next acquisition of the value is 2 ms or more. The progress of the process is put on standby by the process of S128. 2 ms is the same as the time interval at which the value of the jackpot random number counter C1 is updated. When the number of times that the acquired value is determined not to be a special value differs by one time by the processing of S127, the normal processing is started. The number of updates of the jackpot random number counter C1 is different by one, and the value of the jackpot random number counter C1 is different. Therefore, the time interval from the start of startup until the value of the jackpot random number counter C1 becomes the jackpot value in the normal processing can be greatly different for each start-up and for each pachinko machine 10, and fraud It can be surely prevented.

  Here, the time to wait for the progress of the process by the process of S128 does not necessarily have to be the same as the time interval at which the big hit random number counter C1 is updated. Although there is an effect, it is preferable that they are substantially the same. This is because the longer the waiting time, the longer the time for waiting for the progress of the process to be longer than necessary, which hinders the smooth progress of the process. It should be noted that the time to wait for the progress of the process by the process of S128 may be set shorter than the time interval at which the jackpot random number counter C1 is updated, and from the start of startup until the value of the jackpot random number counter C1 is updated to the jackpot value. The time interval can be slightly different for each pachinko machine.

  In the processing of S127, it is not always necessary to compare the read value of the random number generation circuit 507 with the lower 8 bits of the specific code memory 506a. The value of the random number generation circuit 507 may be compared with other bits of the unique code memory 506a, or may be a remainder obtained by dividing the value of the unique code memory 506a, and the value of the unique code memory is composed of 1 byte. When the value is set to a value smaller than the random value that can be generated by the random number generation circuit 507, the value of the unique code memory 506a may be directly compared with the value of the random number generation circuit 507. Also, two or more values such as “2 or less” or “100 or more” may be used as a criterion for comparison with the value of the random number generation circuit 507.

  Further, the value to be compared with the value of the random number generation circuit 507 may be a predetermined fixed value (for example, “1”). Since a process for referring to the value of the unique code memory 506a is not required, the program can be simplified. Further, a counter for counting the number of executions of the process of S126 is provided in the RAM 503 of the MPU 501, and the value of the random number generation circuit 507 is the same as the lower 8 bits of the specific code memory 506a even if the value of the counter exceeds a predetermined number. If not, the wait process (S150) may be terminated and the process may proceed toward the normal process. By setting an upper limit for the time during which the progress of the process is waited by the wait process (S150), it is possible to smoothly shift to the subsequent process.

  Here, another embodiment different from the above-described embodiment (hereinafter abbreviated as “first embodiment” as appropriate) will be described with reference to FIG. FIG. 35 is a flowchart showing the wait process (S150) in the second embodiment. Hereinafter, the same reference numerals are given to the same parts as those in the first embodiment, and the description thereof is omitted, and only different parts will be described.

  In the wait process (see S102 in FIG. 27) in the first embodiment, the process wait time is changed using the random number generated by the random number generation circuit 507 and the value of the unique code memory 506a. It was. In contrast, in the second embodiment, part of the weight processing is different from that in the first embodiment, and the weight processing (S150) in the second embodiment is written in the weight memory 503b. By changing the value in accordance with the value of the unique code memory 506a, the time for which the process is on standby is varied.

  In the wait process (S150) of the second embodiment, first, “500” is written into the wait memory 503b (S121), and the time for waiting for the progress of the process is 1 second. Thereafter, the lower 10-bit value of the unique code memory 506b is read from the ID ROM 506 (S151), and the read value of the unique code memory 506a (lower 10 bits) is added to the value of the wait memory 503b (S152). The initial value corresponding to the waiting time is set in the wait memory 503b. Since the value of the unique code memory 506a is a unique value set differently for each pachinko machine, the value added to the value of the weight memory 503b differs for each pachinko machine and is set in the wait memory 503b. The initial value varies depending on the pachinko machine.

  Thereafter, the same processing from S122 to S124 as described above is performed, the value of the wait memory 503b is subtracted by “1” every 2 ms, and the processing is repeated until the value of the wait memory 503b becomes “0”. After waiting for the progress of the process toward the normal process, the wait process (S150) is terminated and the process proceeds toward the normal process. At this time, the value added by the process of S152 is in the range of “0” to “1023”, and the number of times of repeating the process of S122 to S124 is within the range of “500” to “1523”. Everything will be different. The waiting time varies from 1 second corresponding to the minimum “500” to about 3 seconds corresponding to the maximum “1523”. Therefore, the duration time of the standby state for the plurality of pachinko machines 10 is different for each pachinko machine, and the elapsed time until the big hit random number counter C1 becomes the big hit value is different for each pachinko machine. It is possible to prevent fraud using a fraudulent board.

  In the pachinko machine 10, a payout permission command is transmitted to the payout control device 311 after the wait process (S150), and is performed after the process proceeds to the normal process in the process of S122. Since the progress of the process is started when it is determined by the process of S122 that the standby time of 1 second or more has elapsed in accordance with the value of the unique code memory 506a, the payout control device 311 sets the minimum standby time. While setting a sufficient waiting time until preparation is possible, the time interval from the start of startup to the start of normal processing can be made different for each pachinko machine.

  Here, in the conventional pachinko machine, since the waiting time has not been changed, only the processing in which the main control device 261 waits for a certain period of time for the rise of the dispensing control device 311 (the processing from S121 to S124 in FIG. 35) is provided. It was done. On the other hand, by simply adding the processing of S151 and S152, the waiting time is made different for each pachinko machine while using the conventional processing used in the control of each control device 261, 311 to prevent fraud. Can be planned. Therefore, the design required for preventing fraud can be facilitated and the cost associated with the design change can be reduced.

  In the process of S151, only the lower 10-bit value of the value in the unique code memory 506a is read as information, and the process proceeds to the normal process when the waiting time corresponding to the read value has elapsed. For this reason, even if the number of types of the unique code memory 506a increases, the passage of the waiting time corresponding to each converted information composed of lower bits is judged by the processing of S122, and the upper limit is about 3 seconds at the maximum. It can be provided to allow the processing to proceed toward normal processing. Therefore, normal processing can be started smoothly without prolonging the standby state more than necessary.

  It is also conceivable that a fraudulent act is performed by grasping the timing at which normal processing is started from the timing at which a specific command such as a payout permission command transmitted to the payout control device 311 is transmitted as an unauthorized board. For this reason, in the wait process (S150) for waiting for the progress of the process, the process for changing the time interval from the start of startup to the start of the normal process for each pachinko machine (from S151, S152 and S122 in FIG. 35). The process up to S124) is after the process of sending a payout permission command to the payout control apparatus 311 (the process of S103 in FIG. 26) and before the start of the normal process (for example, between the processes of S103 and S104). You may make it do. Waiting for the progress of the process for a different waiting time for each pachinko machine by the wait process after the payout permission command is transmitted, and then proceeding to the normal process. Therefore, the time interval between the timing at which the main controller 261 transmits the payout permission command and the timing at which the normal process is started can be made different for each pachinko machine, and the transmission timing of a specific command is monitored. It is possible to prevent illegal acts.

  Next, 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, each process of S201 to S207 is executed as a periodic process with a period of 4 ms, and the counter update process of S209 and S210 is executed in the remaining time.

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45 when the large symbol symbol display device 42 displays the variation of the large symbol symbol. In addition, after the start of large symbol variation, one each time in the normal process in the order of variation pattern command → stop symbol command of the left symbol sequence → stop symbol command of middle symbol sequence → stop symbol command of the right symbol sequence (that is, one each in the order of normal processing) The command is transmitted once every 4 ms), and the confirmation command is transmitted at the end of the fluctuation time.

  Next, each value of the variation type counters CS1 and CS2 is updated (S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in 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. Further, the off symbol counters CL, CM, and CR of the left symbol row, the middle symbol row, and the right symbol row are updated by the off symbol counter updating process (S203).

  Here, with reference to FIG. 29, the off symbol counter update processing will be described. First, it is determined whether or not it is time to update the left symbol row out symbol counter CL (S301). If it is the update time (S301: Yes), the out symbol symbol CL out of the left symbol row is updated (S303). Next, if it is not the update time of the left symbol row (S301: No), it is determined whether or not it is the update time of the out-of-middle symbol row symbol counter CM (S302), and if it is the update time (S302: Yes), The out symbol counter CM of the middle symbol row is updated (S304). Furthermore, if it is not the update time of the middle symbol row (S302: No), it is the update timing of the right symbol row, so the outlier symbol counter CR of the right symbol row is updated (S305).

  In updating outlier symbol counters CL, CM, and CR in each of the processes of S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is added when the addition result exceeds the maximum value. Subtraction is performed, and the result of the calculation is taken as the current value of the symbol counters CL, CM, CR. According to the update process of CL, CM, CR, the outlier counters CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row are sequentially updated one by one in one normal process. The update time of each counter value does not overlap. Thus, every time the normal process is executed three times, the set symbol counters CL, CM, and CR are updated for one set.

  Thereafter, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination (S306). If the symbol combination is a jackpot symbol combination (S306: Yes), this processing is performed as it is. finish. If it is not a jackpot symbol combination (S306: No), it is determined whether or not it is a reach symbol combination (S307). If it is a reach symbol combination (S307: Yes), then it is a front-rear reach. It is determined whether or not there is (S308). If it is a combination of front and rear detach reach (S308: Yes), the combination of the detachment symbol counters CL, CM and CR at that time is stored in the front and rear detach reach symbol buffer of the RAM 503 (S309). If the out symbol counters CL, CM, CR are combinations other than front / rear out of reach (S308: No), the combination of out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer except for front / rear out of RAM 503 (S310). ). If the combination of the off symbol counters CL, CM, CR is not a jackpot symbol combination (S306: No) and is not a reach symbol combination (S307: No), the combination of the off symbol counters CL, CM, CR is an off symbol. In such a case, the combination of the off symbol counters CL, CM, CR is stored in the complete off symbol buffer of the RAM 503 (S311).

  After completion of the off symbol counter CL, CM, CR update process (S203), the process returns to the normal process of FIG. 28, reads the winning ball count signal and the payout abnormality signal received from the payout control device 311 (S204), A large symbol variation process for performing variation display of a large symbol on the display device 42 is executed (S205). By this big game symbol variation processing, jackpot determination, large symbol variation pattern setting, and the like are performed. Details of the large symbol variation process will be described later with reference to FIG.

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

  Next, display control of the accessory symbol (eg, “O” or “X” accessory symbol) by the accessory symbol display device 41 is executed (S207). Briefly, on the condition that the game ball has passed the accessory gate (through gate) 34, the value of the accessory symbol random number counter C4 is acquired each time and the accessory 43 is displayed on the accessory symbol display device 41. Symbol variation display is performed. Then, a small symbol drawing is performed according to the value of the small symbol random number counter C4, and when the small symbol wins, the electric accessory associated with the big mouth 33 is released for a predetermined time. Although illustration is omitted, the small symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 32, similarly to the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3.

  Thereafter, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 ms in the present embodiment) has elapsed since the start of the previous normal process (S208). If (S208: Yes), the process proceeds to S201, and the processes after S201 described above are repeatedly executed.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal processing (S208: No), the random number initial is within the remaining time until the predetermined time is reached, that is, until the next normal processing execution timing. The value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated (S209, S210). First, the random number initial value counter CINI is updated (S209). 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. Next, the fluctuation type counters CS1 and CS2 are updated (S210). 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 S201-S207 changes according to the state of the game, the remaining time until the next normal process execution timing 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 large symbol variation processing (S205) will be described with reference to the flowcharts of FIGS. In the large symbol variation process, first, it is determined whether or not a big hit is currently being made (S401). The jackpot includes a jackpot game displayed on the big symbol display device 42 when a jackpot is won and a predetermined time after the jackpot game is over. As a result of the determination, if it is a big hit (S401: Yes), this processing is terminated as it is.

  If it is not during the big hit (S401: No), it is determined whether or not the large symbol display is being displayed by the large symbol display device 42 (S402), and if it is not during the large symbol variation display (S402: No), It is determined whether or not the number N of active suspension balls of the large symbol display device 42 is greater than 0 (S403). If the number N of active suspension balls is 0 (S403: No), this process is ended as it is. If the number of the operation holding balls N> 0 (S403: Yes), the operation holding ball number N is decremented by 1 (S404), and the data stored in the holding ball storage area is shifted (S405). This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area. After the data shift processing, large symbol variation start processing is executed (S406). The variation start process will be described later with reference to FIG.

  In the process of S402, when the large symbol design is being displayed (S402: Yes), it is determined whether or not the variation time has elapsed (S407). The variation time of the large symbol is determined according to the variation pattern of the large symbol, and the execution of the process of S408 is skipped until the variation time elapses (S407: No). On the other hand, if the fluctuation time of the large symbol has elapsed (S407: Yes), a confirmation command set for the confirmation of the stop symbol is set (S408), and this process is terminated.

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

  When it is determined that the game is a big hit (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol is obtained based on a table (not shown) representing the corresponding relationship, and the symbol is set as a stop symbol command (S502). At this time, the numbers 0 to 49 of the jackpot symbol counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. Of these jackpot symbols, if they are arranged with a predetermined specific symbol (probability variation symbol), they will shift to the probability variation state. However, if they are arranged with a predetermined symbol (non-probability variation symbol), the probability change will occur. Does not enter state.

  Next, the variation pattern of the big game symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command (S503). At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach type such as normal reach, super reach, premium reach, and other rough types are determined based on the value of the first variation type counter CS1. And the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) Etc., to determine a finer pattern variation mode. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, 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 the pattern or to set the pattern with both values of both variation type counters CS1 and CS2 is appropriately determined according to the value of the first variation type counter CS1 and the game conditions each time. The same applies to the setting of the fluctuation pattern in the case of performing front / rear out of reach display, reach display other than front / rear out, and complete out of display described later.

  If it is determined in step S501 that the game is not a big hit (S501: No), it is determined whether or not a reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area ( If a reach has occurred (S504: Yes), it is also determined whether or not the front / rear reach has been reached based on the value of the reach random number counter C3 (S505). In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 238, of which “0, 1” corresponds to the 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).

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

  When a reach other than front / rear out is generated (S505: No), the values of 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. (S508). Further, a variation pattern for reach display other than front / rear deviation is determined, and the variation pattern is set in a variation pattern command (S509). 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 the process of S503.

  If neither big hit nor reach (S501: No, S504: No), the left, middle, and right outlier counters CL, CM, and CR stored in the RAM503 complete out symbol buffer are stopped. The symbol command is set (S510). Also, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command (S511). 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 the process of S503. 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.

  Next, payout control executed by the MPU 511 in the payout control apparatus 311 will be described with reference to FIG. FIG. 36 is a flowchart showing a main process of the payout control device 311. This main process is started by a reset at power-on.

  First, initial setting processing accompanying power-on is executed (S901). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Next, it waits for reception of the payout permission command transmitted from the main controller 261 (S902: No). When a payout permission command is received (S902: Yes), RAM access is permitted (S903), and an external interrupt vector is set (S904).

  Thereafter, data backup processing is executed for the RAM 513 in the MPU 511. Specifically, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (S905). If it is turned on (S905: Yes), the backup data is cleared (erased). The process proceeds to S915. On the other hand, if the RAM erasure switch 323 is not turned on (S905: No), it is further determined whether or not the information on occurrence of power interruption is stored in the backup area 513a of the RAM 513 (S906). (S906: No), since the backup data is not stored, in this case as well, the process proceeds to S915. If the occurrence information of the power shutdown is stored in the backup area 513a (S906: Yes), the RAM judgment value is calculated (S907), and the calculated RAM judgment value is not normal (S908: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S915. As described above, the RAM determination value is a checksum value at a work area address of the RAM 513, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 513 is correctly stored.

  In the RAM initialization processing from S915, the used area of the RAM 513 is cleared to 0 (S915), and the initial value of the RAM 513 is set (S916). Thereafter, the MPU 511 peripheral device is initialized (S917), an interrupt is permitted (S918), 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 (S905: No), the occurrence information of the power shutdown has been set (S906: Yes), and the RAM judgment value (checksum value etc.) is normal ( S908: Yes), processing at power recovery (processing at power-off restoration) is executed. That is, the stack pointer at the time of power shutdown is restored (S909), and the information on occurrence of power shutdown is cleared (S910). Also, the MPU 511 peripheral device is initialized (S911), and the used registers are restored from the backup area 513a of the RAM 513 (S912). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S913). If the interrupt is permitted (S913: Yes), the interrupt is permitted (S914), while the interrupt is prohibited when the power is turned off. If it is in the state (S913: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, payout control processing will be described with reference to the flowchart of FIG. This payout control process is executed following the main process of the payout control device 311. In the payout control process, first, a command from the main control device 261 is acquired, and the total number of winning balls is stored (S1001). A launch permission is set for the launch control device 312 (S1002), and when the state return switch 321 is checked, if it is determined that the state return operation is started, the state return operation is executed (S1003).

  Thereafter, the setting of the lower plate full tank state or the lower plate full tank release state is executed according to the change in the state of the lower plate 15 (S1004). That is, when the lower plate 15 is full based on the detection signal of the lower plate full switch, when the lower plate is full, the setting of the lower plate full state is executed. , Set the lower pan full release state. Further, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change in the state of the tank ball (S1005). That is, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when the tank ball is not used, the tank ball no state setting is executed. Perform configuration. Thereafter, the presence / absence of a notification state is determined, and if there is a notification state, notification is made by a 7-segment LED provided in the payout control device 311 (S1006).

  Next, prize ball payout processing is executed by each processing of S1007 to S1009. That is, if the prize ball is not paid out and the total number of prize balls stored in S1001 is not 0 (S1007: No, S1008: No), the prize ball control process shown in FIG. 38 is started (S1009). . On the other hand, if the prize ball cannot be paid out (S1007: Yes) or if the total number of prize balls is 0 (S1008: Yes), the process proceeds to the lending and payout process. The prize ball control process will be described later.

  In the rental ball payout process of S1010 to S1012, if the ball payout is not disabled and a ball ball payout request is received from the card unit (S1010: No, S1011: Yes), the ball rental shown in FIG. Control processing is started. On the other hand, if the rental ball cannot be dispensed (S1010: Yes) or if a rental ball dispensing request has not been received (S1011: No), the subsequent ball removal process is executed (S1013). The ball rental control process will be described later.

  In the ball removal process (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 is not disabled and the ball removal operation is not started. Subsequently, the control of the vibrator 360 (vibration motor control) is executed on the condition that the ball is clogged (S1014). Thereafter, the process returns to the top of the payout control process, and thereafter the above-described process is repeated.

  The prize ball control process shown in FIG. 38 will be described. In the winning ball control process, firstly, the payout motor 358a is driven to rotate in the forward direction to pay out the winning ball (S1101). Whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (S1102). If not normal (S1102: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a. The stop process is executed (S1103), and then the process returns to the payout control process of FIG.

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

  Further, if the game ball count is normal (S1104: Yes), it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout is completed (S1106). If completed (S1106: Yes), a stop process of the payout motor 358a is executed (S1107), and then the process returns to the payout control process of FIG. On the other hand, if the payout has not been completed (S1106: No), the process returns to the payout control process of FIG.

  The lending control process shown in FIG. 39 will be described. In the ball lending control process, firstly, the payout motor 358a is driven to rotate in the reverse direction to execute lending of a lending ball (S1201). Whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (S1202). If not normal (S1202: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a Is stopped (S1203), and then the process returns to the payout control process of FIG.

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

  Further, if the game ball count is normal (S1204: Yes), it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed ( If the payout is completed (S1206: Yes), the payout motor 358a is stopped (S1207), and then the payout control process of FIG. 37 is returned to. On the other hand, if the payout has not been completed (S1206: No), the process returns to the payout control process of FIG.

  The present invention has been described above based on one embodiment. However, the present invention is not limited to the above embodiment, and various modifications and improvements can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, as shown in the above embodiment, the variable display, which is a kind of dynamic display, is not limited to the one that scrolls the symbol as identification information in the vertical direction on the display screen of the large symbol display device 42, but in the horizontal direction. Alternatively, it may be performed by moving and displaying a symbol along a predetermined route such as an L shape. In addition, the dynamic display of the identification information is not limited to the display of variation of the symbol. For example, one or a plurality of characters may be displayed in various manners together with the symbol or displayed in a variety of manners separately from the symbol. The effect display etc. which are displayed are also included. In this case, one or a plurality of characters are used as identification information together with the symbols or separately from the symbols.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, the present invention may be applied to a so-called second type pachinko gaming machine having a winning device having a special area such as a V zone. Further, in addition to the pachinko machine, the game machine may be implemented as another game machine such as an alepacchi or a sparrow ball. Further, in addition to the pachinko machine, various game machines such as an alepacchi, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are fused may be used.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Therefore, the basic concept of the slot machine is that “a variable display means for confirming and displaying a symbol after a symbol string composed of a plurality of symbols is displayed in a variable manner, and the symbol resulting from the operation of the starting operation means (for example, an operating lever). The change of the symbol is stopped due to the operation of the operation means for stopping (for example, the stop button) or after a predetermined time has elapsed, and the fixed symbol at the time of the stop is a specific symbol Is a slot machine provided with a special game state generating means for generating a special game state advantageous to the player. In this case, the game medium is typically a coin, a medal or the like.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are integrated, a variable display means for displaying a symbol after a symbol string composed of a plurality of symbols is displayed, and a handle for launching a ball is provided. What is not provided. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  The gaming machine and modified examples of the present invention are shown below. A random number counter, an updating means for updating the value of the random number counter within a predetermined range at regular intervals, an initial value setting means for setting the value of the random number counter to an initial value, and detection of establishment of a predetermined gaming condition And a game state for generating a game state advantageous to the player on condition that the value of the random number counter is a predetermined value when the detection of the game condition is detected by the detection unit A start-up process for performing an initial setting including an initial value setting by the initial-value setting means at the time of start-up, and updating of the value of the random number counter by the update means and the detecting means after the start-up process Control means for executing normal processing that repeats the detection of establishment of the gaming condition by the control means, and the control means stores unique information set differently for each gaming machine Whether or not to proceed to the normal process depending on whether or not a predetermined condition corresponding to the unique information stored in the unique information storage means is provided in a part of the startup process. A game machine 1 characterized in that a time interval from the start of startup to the start of the normal process corresponds to the specific information. .

Incidentally, the unique information in Yu Move machine 1 is information that is set different for each game machine, the unique information storage unit (e.g., ROM or EEPROM, and the like), for example, is stored as binary data ing. As the unique information, for example, a manufacturing number (ID) set so as not to be duplicated for each gaming machine manufacturer, for each gaming machine model, or for each gaming machine component (for example, a control device represented by MPU). No.) for specifying the production time and the production lot. Further, whether or not the process proceeds toward the normal process means whether the process proceeds toward the normal process or whether the process toward the normal process is awaited. Progressing the process toward the normal process means the start of the normal process or the start of the process provided between the normal process and the process constituting the determination means. Waiting means delaying the start of normal processing or the start of processing provided between the normal processing and the processing constituting the determining means by repeatedly performing some processing.

As the random number counter in the Yu technique machine 1, is exemplified jackpot random number counter C1 in the above embodiment, the updating means is exemplified process S603 in the timer interrupt processing shown in FIG. 32, actuation port as a detecting means The process of S701 in FIG. 33 for detecting the winning to the switch 224 is exemplified, and the initial value setting means is exemplified by the process for initial setting of the RAM 503 of the main controller 261 (the process of S115 in FIG. 26). Examples of the changing means include normal processing (particularly, each processing of S201, S205, and S206 in FIG. 28) performed by the main controller 261. In the first embodiment, the determination unit exemplifies the process of S127 in FIG. 27. In the second embodiment, the determination unit exemplifies the process of S122 in FIG.

  In the gaming machine 1, the determination means determines whether or not to proceed to the normal process according to whether or not a standby time corresponding to the specific information stored in the specific information storage means has elapsed. A gaming machine 2 that is characterized by

  According to the gaming machine 2, the determining means determines whether or not to proceed the process toward the normal process depending on whether or not the standby time corresponding to the unique information stored in the unique information storage means has elapsed. If it is determined by the determination means that the standby time corresponding to the specific information has elapsed, the process proceeds to the normal process. Here, since the unique information is set differently for each gaming machine, the standby time corresponding to the unique information is different for each gaming machine. Therefore, it is possible to prevent fraud by changing the time interval from the start of startup to the start of normal processing for each gaming machine. In addition, as a determination means in the gaming machine 2, the process of S122 of FIG. 35 in the second embodiment is exemplified.

  The gaming machine 2 includes sub-control means that is formed separately from the control means and starts predetermined control on a predetermined device based on a specific command transmitted from the control means, and the determination means includes It is determined whether or not to proceed to the normal process according to whether or not a waiting time that is a certain length or longer has elapsed in the startup process corresponding to the specific information. The control means includes command transmission means for transmitting the specific command to the sub-control means during the startup process after the process proceeds to the normal process according to the determination of the determination means. A gaming machine 3 characterized by When controlling a gaming machine using a plurality of control means, it may be necessary to synchronize the control of each control means, but the time required for startup differs for each control means It is. For this reason, the control means that starts up in a short time may wait for the progress of processing until another control means starts up. In addition, in a gaming machine in which the control means having a random number counter starts up in a shorter time than the sub control means, the progress of the process may be waited until the sub control means starts up after the start up.

  According to the gaming machine 3, a specific command is transmitted to the sub-control means during the start-up process, and the specific command is performed after the process is advanced by the determination means. The determination means determines that the process is to proceed when the standby time of a certain length or more corresponding to the specific information has elapsed, and is sufficient to prepare the control of the sub-control means as the minimum standby time. The time interval from the start-up to the start of normal processing can be made different for each gaming machine while setting a long standby time. Therefore, it is possible to prevent fraud while using the process of waiting for the progress of the process used in the control of the control means and the sub-control means from the past. Cost associated with the change can be reduced.

  In the gaming machine 3, the control means includes a standby value storage means for storing a value corresponding to the standby time, a standby value update means for subtracting and updating a value stored in the standby value storage means, and the standby A standby value setting means for setting an initial value in the value storage means; and an initial value set by the standby value setting means by adding a value corresponding to the specific information to a value corresponding to the predetermined length of standby time. A gaming machine 4 comprising standby value calculation means for calculating. In a conventional gaming machine, there is a process in which a standby value storage unit, a standby value update unit, and a standby value setting unit are provided as a process for waiting for the progress of the process. The initial value set by the standby value setting means is subtracted by the standby value update means to gradually reduce the value corresponding to the standby time, and when the value reaches a predetermined value (for example, “0”) The progress of the process is started as time passes.

  According to the gaming machine 4, the initial value set by the standby value setting means is calculated by adding a value corresponding to the specific information to a value corresponding to a predetermined length of standby time by the standby value calculation means. The initial value is a value corresponding to the unique information and is different for each gaming machine. Therefore, for conventional gaming machine control, the time interval from the start-up to the start of normal processing can be made different for each gaming machine simply by adding standby value calculation means, and there are few design changes Can prevent fraud. Note that “Calculate the initial value by adding the value corresponding to the specific information to the value corresponding to a certain time ...” calculates the value corresponding to the waiting time longer than a certain time corresponding to the specific information. For example, the initial value is calculated by adding a value corresponding to the unique information or multiplying the value corresponding to the unique information. Further, as the standby value storage means in the gaming machine 3, for example, the wait memory 503b provided in the RAM 503 of the main controller 261 (MPU 501) in the second embodiment described above is exemplified, and the standby value update means is illustrated in FIG. The process of S123 is illustrated, and the process of S152 of FIG. 35 is illustrated as the standby value setting means and the standby value calculation means.

  The gaming machine 2 includes sub-control means that is formed separately from the control means and starts predetermined control on a predetermined device based on a specific command transmitted from the control means, and the control means A game transmission means comprising command transmission means for transmitting the specific command to the sub-control means before the progress of the process toward the normal process is waited by the determination means during the startup process. Machine 5. The output timing of the command transmitted to the sub-control means as an illegal board is monitored, and when the normal processing is started after a lapse of a certain time from the output timing, the start timing of the normal processing is easily grasped, and the random number counter is set to a predetermined value. It is conceivable that a fraudulent act of inputting a fraudulent signal to the detection means aiming at the timing of the value is performed. For this fraudulent act, it is preferable to make the time interval between the timing at which a specific command is transmitted from the control means to the outside and the timing at which normal processing is started undefined.

  According to the gaming machine 5, a specific command is transmitted to the sub-control means during the start-up process, and the specific command is received by the determination means before waiting for the progress of the process toward the normal process. To be done. For this reason, after a specific command is transmitted, the progress of the process is waited for a different waiting time for each gaming machine corresponding to the unique information, and then the process proceeds to the normal process according to the determination of the determination means. . Therefore, the time interval between the timing at which a specific command is transmitted by the control means and the timing at which normal processing is started can be made different for each gaming machine, and fraud is performed by monitoring the timing of transmission of a specific command. Actions can be prevented in advance.

  In any of the gaming machines 2 to 5, the game machine includes first conversion means for converting the unique information stored in the unique information storage means into numerical information within a certain range, and the determination means is converted by the first conversion means. The gaming machine 6 is characterized in that it is determined whether or not the process proceeds to the normal process in accordance with whether or not the standby time corresponding to the numerical value information has passed. Since the unique information is set differently for each gaming machine, the type of unique information increases in proportion to the number of gaming machines having the unique information. For this reason, if a waiting time for waiting for the progress of processing is set for each unique information, the waiting time becomes too long when the number of kinds of unique information increases, and an unnecessary time is required until the start of normal processing (game). Can occur.

According to the gaming machine 6, the unique information is converted into numerical information within a certain range, and when the standby time corresponding to the converted numerical information elapses, the process proceeds to the normal process. For this reason, even if the number of types of unique information increases, it is judged by the judging means that the waiting time corresponding to each converted numerical information has been separately processed, and the processing is performed within the predetermined waiting time for normal processing. Can proceed. Therefore, normal processing can be started smoothly without prolonging the standby state corresponding to the specific information more than necessary. As the first converting means in Yu TECHNICAL machine 6, the processing of S151 of FIG. 35 in the second embodiment is illustrated.

  In the gaming machine 1, the control unit includes a random number generation unit that generates a random value separately from the random number counter, and a random number acquisition unit that acquires a value generated by the random number generation unit, and the determination unit includes: In accordance with whether or not the value acquired by the random number acquisition means is a value corresponding to the unique information stored in the unique information storage means, it is determined whether or not to proceed to the normal process. Yes, the control means acquires the value by the random number acquisition means and the value acquired by the determination means when the determination means determines that the value acquired by the random number acquisition means is not a value corresponding to the unique information The determination unit determines that the value acquired by the random number acquisition unit is a value corresponding to the specific information by repeating the determination of the value and waiting for the process to proceed to the normal processing. Gaming machine 7, characterized in that said advancing process toward the normal process when it is disconnected.

According to the gaming machine 7, when the determination unit determines that the value acquired by the random number acquisition unit is not a value corresponding to the unique information, the acquisition of the value by the random number acquisition unit and the determination of the value acquired by the determination unit are performed. The process is repeated and the progress of the process toward the normal process is put on standby. When the determination unit determines that the value acquired by the random number acquisition unit is a value corresponding to the unique information, the process proceeds to the normal process. Here, since the unique information is set differently for each gaming machine, the value corresponding to the unique information differs for each gaming machine, and the value acquired by the random number acquisition means corresponds to the unique information. The number of times the random number is acquired until the value is obtained is undefined for each gaming machine. Therefore, the time interval from the start of startup to the start of normal processing can be made different for each gaming machine, and illegal acts can be prevented. As the Yu technique machine 7, for example, the pachinko machine 10 in the first embodiment is illustrated, the random number generator 507 as the random number generating means, a random number acquisition means the process of S126 of FIG. 27, determination As the means, the process of S127 of FIG. 27 is exemplified.

  In the gaming machine 7, when the determination unit determines that the value acquired by the random number acquisition unit is not a value corresponding to the specific information and repeats the acquisition of the value by the random number acquisition unit, the value is acquired before Random number acquisition waiting means for waiting for the progress of processing so that the time interval from the next acquisition of a value to a certain length or more is maintained, and the value of the random number counter is updated by the updating means for the fixed length The gaming machine 8 is set to be equal to or longer than the time interval set.

  According to the gaming machine 8, when the determination unit determines that the value acquired by the random number acquisition unit is not a value corresponding to the unique information, the time from the previous acquisition of the value to the next acquisition of the value The progress of the process is made to wait by the random number acquisition waiting means so that the interval becomes a certain length or more. The fixed length is set equal to or longer than the time interval at which the value of the random number counter is updated. For this reason, in a plurality of gaming machines, if the number of times that the value acquired by the random number acquisition means is determined not to be a value corresponding to the unique information is different even once, a certain time elapses from the start of startup and the normal processing is performed. In this case, the number of updates of the random number counter is different by one, and the value of the random number counter is different. Therefore, the time interval from the start of start-up until the value of the random number counter is updated to a predetermined value can be greatly varied for each gaming machine, and illegal acts can be prevented more reliably. As the random number acquisition standby unit, for example, the process of S128 of FIG. 27 is exemplified.

  In the gaming machine 7 or 8, the game machine 7 or 8 includes second conversion means for converting the unique information stored in the unique information storage means into numerical information within a certain range in which random number values are generated by the random number generation means, and the determination means includes Determining whether or not to proceed to the normal process depending on whether or not the numerical information converted by the second conversion means matches the value acquired by the random number acquisition means. And the control means acquires the value by the random number acquisition means and the determination means when the value acquired by the random number acquisition means and the converted numerical information are determined to be inconsistent by the determination means The determination of the acquired value is repeated to wait for the process to proceed to the normal processing, and the determination is made that the value acquired by the random number acquisition means matches the converted numerical information Gaming machine 9, characterized in that when it is judged by the step wherein it is usually intended to advance the process toward the process.

According to the gaming machine 9, the unique information is converted into numerical information within a certain range in which random number values are generated by the random number generating means, and the converted numerical information and the value acquired by the random number acquiring means match. Processing proceeds when the condition is met. For this reason, even if the type of unique information is larger than the type of random value generated by the random number generation means, the unique information and the random number value can be associated with each other reliably, and normal processing is started from the start of startup. The time interval until can be made different for each gaming machine. As the second conversion means in Yu TECHNICAL machine 9, for example, the process of S127 of FIG. 27 is illustrated.

  The gaming machine 10 according to any one of the gaming machines 1 to 9, wherein the gaming machine is a pachinko gaming machine. Above all, the basic configuration of a pachinko gaming machine is provided with an operation handle, and according to the operation of the operation handle, a game ball is launched to a predetermined game area, and the game ball is arranged at a predetermined position in the game area As a necessary condition for winning a prize in the mouth (or passing through the operating mouth), the identification information dynamically displayed on the display device is confirmed and stopped after a predetermined time. In addition, when a predetermined game value is given, a variable winning device (specific winning port) disposed at a predetermined position in the gaming area is opened in a predetermined manner so that game balls can be won, and the number of winning To which a valuable value (including data written on a magnetic card as well as a prize ball) is given.

  The gaming machine 11 according to any one of the gaming machines 1 to 9, wherein the gaming machine is a slot machine. Above all, the basic configuration of the slot machine is “equipped with variable display means for confirming and displaying the identification information after dynamically displaying an identification information string composed of a plurality of identification information, and for operating the starting operation means (for example, an operation lever). As a result, the dynamic display of the identification information is started, and the dynamic display of the identification information is stopped due to the operation of the stop operation means (stop button) or after a predetermined time has elapsed.
