However, there is a case where an unauthorized board is attached to a main control device or the like that performs a winning lottery based on the value of the winning random number counter, and an illegal act that causes an unfair win is performed. The place suffers great damage.

However, since the timing at which the main control device starts the initialization process and the initialization command is transmitted to each peripheral control device is substantially constant, the illegal board is one of the following first to third Depending on the method, the initialization command transmitted from the main control device cannot be received by each peripheral control device, or even if it can be received, the received initialization command is deleted and the initialization status can be notified. There is a problem that it can be considered that fraud is performed without it.
That is, firstly, the unauthorized substrate outputs a reset signal to each peripheral control device immediately after each peripheral control device receives the initialization command, and illegally resets each peripheral control device. Since each peripheral control device executes each initialization process by reset, the initialization command received before the reset is erased and has not been received. As a result, the initialization state cannot be notified. Secondly, the unauthorized board outputs a reset signal to each peripheral control device and resets each peripheral control device illegally at a timing immediately before the initialization command is transmitted from the main control device. Each peripheral control device executes each initialization process by reset, but the initialization process requires a certain amount of time, and during that time it cannot receive commands, so the initialization command sent from the main control device Therefore, it is impossible to report the initialization state by the initialization command. Third, separately from the illegal board, an integration circuit composed of a capacitor or the like is connected to at least one of the command transmission / reception lines of the main control device and each peripheral control device to initialize the main control device. After the processing, until the initialization command transmission is completed, the signal of that line is regarded as abnormal so that the normal initialization command cannot be received by each peripheral control device, thereby informing the initialization state. Make it impossible.
The present invention has been made to solve the above-described examples and the like, and an object thereof is to provide a gaming machine that can prevent an illegal act by an illegal board.

In order to achieve this object, a gaming machine according to claim 1 includes a memory whose value can be rewritten in units of areas , a counter provided in the first area of the memory , and a value of the counter within a predetermined range. Update means for updating to be used, a second counter provided in the second area of the memory, and a second counter for updating the value of the second counter to be used within the same predetermined range as the counter. 2 update means, and when the update means has updated the counter in n cycles (n is a natural number), the update of the counter is performed based on the value of the second counter updated by the second update means. An initial value changing means for changing the initial value, a detecting means for detecting the establishment of the first predetermined condition, and a value of the counter is predetermined when the establishment of the first predetermined condition is detected by the detecting means Predetermined value And a favorable state generating means for generating a beneficial gaming state to the player if further configured to writable values for the memory, and an arithmetic means for performing arithmetic on the control of the game, The calculation means includes a register used for designating an address of an area to be written when a value is written to one area of the memory, and the memory value is initialized by satisfying a second predetermined condition. The initialization process is performed by a memory clear process for clearing the value of the memory, and an initial value is set for each area of the memory after the memory clear process. A memory initial value setting process, wherein the memory clearing process sets an address of one area of the memory in the register, and the address An address determination process for determining whether the address set in the register by the fixed process is an address of the first area provided with the counter or an address of the second area provided with the second counter; and the address When it is determined that the address set in the register by the determination process is the address of the first area or the address of the second area, the value of the area of the address is maintained and set in the register by the address determination process And clear control processing for clearing the value of the area of the address when the determined address is determined to be an address other than the first area and an address other than the second area. is intended to run against the region, the memory initialization value setting process, the value of said counter and said second counter, said counter As data and values of the second counter is used within the predetermined range, respectively, clear the portion of the predetermined bit or a predetermined number of bytes of all bits or all bytes constituting the counter and the second counter The predetermined bit or predetermined byte is cleared by a predetermined bit set when the counter or the second counter indicates a maximum value from the most significant bit of the counter or the second counter.

  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail with reference to 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. A speaker hole 24 for outputting sound from the speaker is formed in the front panel.

  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 displays a small symbol display device 41 that variably displays a normal symbol triggered by the passage of a game ball through the accessory gate 34, and a special symbol variably when triggered by winning a game ball at the big mouth 33. A large symbol display device 42 as a symbol display device is provided. The accessory symbol display device 41 includes a normal symbol display unit 43 and a holding lamp 44, and each time a game ball passes through the accessory gate 34, the display symbol (ordinary symbol) changes 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 normal symbol variation display is performed by switching the lighting of a plurality of lamps in the display unit 43 as in the present embodiment, or a part of the large symbol display device 42 (liquid crystal display device). 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 is provided with 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 in the big game mouth 33, the special game is based on the requirement that the symbols are variably displayed on the big game symbol display device 42, and the confirmed symbols after the stop are a combination of specific symbols set in advance. A condition occurs. When the special gaming state occurs, the big winning opening of the variable winning device 32 is configured to be in a state where the game ball is likely to win (a big hit state), 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 guided by a ball (a portion on the left side) parallel to each other at a predetermined interval. A passage 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. Further, a return rubber 54 is attached to the outer rail mounting portion 52 at a position corresponding to the maximum flying portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip 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 peripheral portion 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 a plurality of through holes formed in the flange 56. 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 the present embodiment, the game board 30 is formed in the same size as a conventional pachinko machine, and the game area is formed larger than the conventional pachinko machine, so that the rail can be directly driven into the game board. Therefore, the rail unit 50 is integrally formed with resin together with the flange 56, and the flange 56 is fixed to the game board 30 by 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 launch rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the launch rail 61, and is configured to extend linearly at a predetermined launch 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 ball striking ball, and the game ball is fired with the rotation of the ball striking center 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, the 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 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 play a role of enhancing the effect of the game during the game by changing or controlling the light emission mode by turning on or blinking according to the change of the gaming state at the time of big hit or predetermined reach. 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 associated with 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 functions 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, so that the front frame set 14 is closed, and the inner rail portion 51 and the outer rail mounting portion 52 are configured. 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 front open portion 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 a circular arc shape corresponding to the shape of the guide rail, and a front frame set so as to cover a section from the base end portion of the guide rail to the vicinity of the tip 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. 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 intruded through a gap between the front frame set 14 and the inner frame 12 to perform an illegal 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. Note that 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. FIG. 6 is a rear view of the pachinko machine 10, and FIG. 7 is an exploded perspective view showing the rear structure of the pachinko machine 10 exploded for each main part. FIG. 8 is a schematic diagram showing the arrangement of the first control board unit 201, the second control board unit 202, and the back pack unit 203 on the back surface of the pachinko machine 10, and FIG. 9 shows the configuration of the inner frame 12 and the game board 30. FIG. 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.

  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 lined up or down, left or right, or stacked back and forth. 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 “first control board unit 201”, and the latter unit is referred to as “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 provided and can be opened and closed 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 view of FIG. 8, the units 201 to 203 are arranged 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. Further, the back pack unit 203 is arranged in a region partially overlapping the first control board unit 201.

  The first control board unit 201 is provided with a support shaft part M1 at the left end when viewed from the back of the pachinko machine 10, and the first control board unit 201 can be opened and closed around the axis A of the support shaft part M1. It has become. Further, the first control board unit 201 is provided with a fastening portion M2 made of a ny latch or the like at the right end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side), and the locking claw portion M3 at the upper end portion. The first control board unit 201 is fixed and held to the main body of the pachinko machine 10 by the fastening part M2 and the locking claw part M3.

  Further, the second control board unit 202 is provided with a support shaft part M4 at the right end when viewed from the back of the pachinko machine 10, and the second control board unit 202 opens and closes around the axis B of the support shaft part M4. It is possible. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like at the left end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side). 2 The control board unit 202 is fixedly held to the main body of the pachinko machine 10.

  Further, the back pack unit 203 is provided with a support shaft portion M6 at the right end when viewed from the back of the pachinko machine 10, and the back pack unit 203 can be opened and closed around an axis C by the support shaft portion M6. Yes. Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like at the left end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side), and the upper end portion and the lower end portion are respectively rotatable. 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 back side 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 does not fall off 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 in a state where 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 disposed 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-sized 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 game board opening of the general prize opening 31, the variable prize winning device 32, and the big prize opening 33 (each see FIG. 4), and gathers in one place on the downstream side. A recovery passageway 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 a ball discharge port (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.

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 content 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 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 cut off 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, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. The power failure signal SG1 is output to the main controller 261 and the payout controller 311. By 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. Note that the power supply unit 541 outputs a voltage of 5 volts, which is a 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 controller 261 and the payout controller 311 can normally execute and complete the NMI interrupt process.

  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 row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-pattern made up of, for example, rhombus-shaped symbols. Each of the main symbols and sub-designs represents a large 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 of 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 you align.

  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, a symbol display setting of the large 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 the initial value setting, random number initial value counter CINI used for initial value setting of the jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the large symbol display device 42, the 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, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using 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). The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in accordance with the winning timing.

  Each counter will be described in detail. The jackpot random number counter C1 is composed of a 2-byte soft counter that is incremented one by one within a range of, for example, 0 to 676 and returns to 0 after reaching the maximum value (that is, 676 (= 2A4h)). Particularly, 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, and the initial value of the update of the jackpot random number counter C1 is changed. The random number initial value counter CINI is composed of 2 bytes like the jackpot random number counter C1, and is configured as a loop counter that is updated in the same range as the jackpot random number counter C1. Therefore, the update range of the random number initial value counter CINI is 0 to 676, and the maximum value is 676 (= 2A4h). The value of the random number initial value counter CINI is updated once every timer interrupt and is repeatedly updated within the remaining time of the normal processing. 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 value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. 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 probability change. (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 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present 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 last stop symbol to stop after the reach has occurred by shifting the last stop symbol by only one before and after the reach symbol, and the last stop symbol after the reach has occurred. “Reach other than front / rear out” and stop “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 large symbols such as so-called normal reach, super reach, premium reach, and other general symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (the 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. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. 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 top, middle and bottom symbols are determined.

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

  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 MPU 501 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 milliseconds (hereinafter referred to as “ms”)). And an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal (non-maskable terminal). For convenience of explanation, the timer interrupt process and the NMI interrupt process are described first, and then the main process Will be explained.

  FIG. 33 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 process of various winning switches is 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).

The 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 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 is not satisfied (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 winning prize), the big game symbol display device 42 starts to display the fluctuation of the big game symbol, but 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 a 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. 35 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 or the like, 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 in FIG. 35 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 controller 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. Thereafter, access to the RAM 503 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and the processing cannot be executed.

  The above NMI interrupt process is executed in the same manner in the payout control apparatus 311. With this NMI interrupt process, the state of the payout control apparatus 311 when the power is cut off 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. 35 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, an initial setting process associated with power-on is executed (S101). Specifically, a predetermined value set in advance in the stack pointer is set, and a sub-side control device (peripheral control device such as display control device 45, audio lamp control device 262, payout control device 311, etc.) operates. In order to wait for a possible state, wait processing (for example, about 1 second) is executed. Thereafter, after a payout permission command is transmitted to the payout control device 311 (S102), access to the RAM 503 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is turned on (S104), and if it is turned on (S104: Yes), processing is performed to clear (erase) the backup data. The process proceeds to S114. On the other hand, if the RAM erasing switch 323 is not turned on (S104: No), it is further determined whether or not the information on the 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 occurrence information of power shutdown is stored in the backup area 503a (S105: Yes), a RAM judgment value is calculated (S106), and if the calculated RAM judgment 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.

  If the RAM erase switch 323 is not turned on (S104: No), the occurrence information of the power shutdown is stored (S105: Yes), and if 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 (the 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), while 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.

  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 S115). 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 S115) of the RAM 503 in the same manner. That is, in the RAM initialization process from S114, a RAM clear process (S114) and a RAM initial value setting process (S115) are executed, and then an interrupt is permitted (S116), and a normal process (see FIG. 29).

  FIG. 27 is a flowchart of the RAM clear process. By this RAM clear processing (S114), the contents of each memory in the RAM 503 other than the big hit random number counter C1 and the random number initial value counter CINI are cleared to zero.

  First, the head address of the RAM 503 is written into the HL register which is a built-in register of the MPU 501 (S131). It is confirmed whether or not the value of the HL register indicates the address of the jackpot random number counter C1 or the random number initial value counter CINI (S132, S133). When neither address is indicated (S132: No, S133: No) The contents of the address indicated by the HL register are cleared to 0 (S134). On the other hand, when the value of the HL register indicates the address of either the jackpot random number counter C1 or the random number initial value counter CINI (S132: Yes or S133: Yes), the execution of the 0 clear process in S134 is skipped, The values of the jackpot random number counter C1 and the random number initial value counter CINI are maintained.

  The value of the HL register is incremented by 1 (S135), and if the value of the HL register after the addition does not exceed the final address of the RAM 503 (S136: No), the process proceeds to S132, and each of the above-described S132 to S136 is performed. Repeat the process. On the other hand, if the value of the HL register exceeds the final address of the RAM 503 (S136: Yes), the values of the RAM 503 can be cleared to 0 except for the values of the jackpot random number counter C1 and the random number initial value counter CINI. In this case, the RAM clear process is terminated.

  FIG. 28 is a flowchart of the RAM initial value setting process. In the RAM initial value setting process (S115), first, values of the RAM 503 other than the jackpot random number counter C1 and the random number initial value counter CINI are set to initial values (S141). Next, it is confirmed whether or not the value of the jackpot random number counter C1 is within the normal range (update range) of “0 to 676” (S142). If it is within the normal range (S142: Yes), the random number initial value It is checked whether or not the value counter CINI is within the normal range of “0 to 676” (S143). If the value of the random number initial value counter CINI is also within the normal range (S143: Yes), both values of the jackpot random number counter C1 and the random number initial value counter CINI are within the normal range. The process proceeds to S148.

  Even if the value of the jackpot random number counter C1 is within the normal range, if the value of the random number initial value counter CINI is not within the normal range (S142: Yes, S143: No), the value of the jackpot random number counter C1 within the normal range Is written to the random number initial value counter CINI (S144). Even if the value of the jackpot random number counter C1 is not in the normal range, if the value of the random number initial value counter CINI is in the normal range (S142: No, S145: Yes), the random number initial value counter in the normal range The value of CINI is written into the jackpot random number counter C1 (S146). Thereby, both values of the jackpot random number counter C1 and the random number initial value counter CINI are maintained at either value.

  On the other hand, if neither of the big hit random number counter C1 and the random number initial value counter CINI is within the normal range (S142: No, S145: No), the upper bytes of the big hit random number counter C1 and the random number initial value counter CINI are each set to 0. Clear (S147). As described above, the jackpot random number counter C1 and the random number initial value counter CINI are each composed of 2 bytes, and the maximum value of the update range is 02A4h. Therefore, by clearing each upper byte to 0, the jackpot random number counter C1 and the random number initial value counter CINI are each initialized to one of 0000h to 00FFh. That is, the jackpot random number counter C1 and the random number initial value counter CINI are values within the update range of the counters C1 and CINI in accordance with the value of the lower byte of each value when the RAM initial value setting process (S115) is executed. It is initialized to any value from 0000h to 00FFh. As described above, if neither of the jackpot random number counter C1 and the random number initial value counter CINI is within the normal range (S142: No, S145: No), the value after the initialization is any of 256 values from 0000h to 00FFh. (Undefined value).

  After setting the initial value of each value in the RAM 503, an initialization command is transmitted to the display control device 45 (S148), and the fact that the initialization process has been executed by the main control device 261 is sent to the display control device 45, which is a peripheral control device. The RAM initial value setting process is terminated. When the display control device 45 receives the initialization command transmitted from the main control device 261, the large-sized symbol display device 42 displays an initial display for notifying the surroundings that the initialization processing has been executed by the main control device 261 for a predetermined time. (For example, 30 seconds) and an initialization command is transmitted to the sound lamp controller 262. When the sound lamp control device 262 receives the initialization command, the sound lamp control device 262 outputs the sound output for notifying the surroundings that the initialization processing has been executed by the main control device 261 and the initial output of blinking the lamp, as with the display control device 45. It is performed for a predetermined time (for example, 30 seconds).

  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 miss symbol counter updating process (S203).

  Here, the off symbol counter update process will be described with reference to FIG. 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). 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. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, 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 other than front / back 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 the completion of the off symbol counter CL, CM, CR update process (S203), the process returns to the normal process of FIG. A large symbol variation process for performing variation display of a large symbol by the symbol 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.

After the big symbol variation process is completed, the 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 a small symbol (for example, a normal symbol of “◯” or “x”) by the small 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 the description is omitted, the small symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 33, like 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 since the start of the previous normal process (S208: No), the random number initial value is within the remaining time until the predetermined time is reached, that is, until the next normal process is executed. 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 to 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 process (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.

  In the process of S402, when the large symbol pattern is being displayed (S402: Yes), it is determined whether or not the variable 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 the 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 it is a big hit (S501: Yes), a table corresponding to the value of the big hit symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the big hit symbol (big hit symbol counter C2 (A table representing the correspondence between the value of the symbol and the symbol), 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 transition to the 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) More detailed pattern variation modes are determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set 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 variation pattern for displaying the front / rear out of reach is determined, and the variation pattern is set in the variation 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 device 311 will be described with reference to FIG. FIG. 36 is a flowchart showing the main process of the payout control apparatus 311. This main process is activated 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 process 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 controller 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 from the lower plate full switch, when the lower plate is full, the lower plate full state is set. , 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). In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration. Thereafter, the presence / absence of a notification state is determined, and if there is a notification state, notification is made by a 7-segment LED provided in the payout control device 311 (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 a lending 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. The stop process is executed (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), and then 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 (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.

  As described above, according to the pachinko machine 10 of the present embodiment, the values of the jackpot random number counter C1 and the random number initial value counter CINI are normal even if the initialization process (S114 to S115) of the RAM 503 is executed. If the value is within the range (within the update range) (0 to 676), it is maintained without being initialized. Further, if the value of one counter C1, CINI is within the normal range, the value of one counter C1, CINI within the normal range is calculated even if the value of the other counter C1, CINI is not within the normal range, By writing to the other counters C1 and CINI that are out of the normal range, the other counters C1 and CINI are not initialized to a specific value (for example, 0), but are maintained at a value within the normal range.

  Further, if neither the big hit random number counter C1 nor the random number initial value counter CINI is within the normal range, the upper bytes of the big hit random number counter C1 and the random number initial value counter CINI are each cleared to zero. As a result, the jackpot random number counter C1 and the random number initial value counter CINI are each one of 256 values of 0000h to 00FFh according to the value of the lower byte when the initialization process (S114 to S115) of the RAM 503 is executed. Initialized to (undefined value).

  The jackpot random number counter C1 is a counter used for the jackpot lottery, that is, a counter for determining the occurrence of the jackpot, and the random number initial value counter CINI is a counter used for setting the initial value of the jackpot random number counter C1. . Therefore, even in the initialization process (S114 to S115), these values are maintained without being initialized, or are initialized to an indefinite value within the normal range, so that the values of both counters cannot be grasped by the illegal substrate. can do. Therefore, even when the reset signal and the RAM erase signal SG2 are illegally output together with the reset signal by the illegal board, both the big hit random number counter C1 and the random number initial value counter CINI related to the big hit generation determination are initially set to specific values. Therefore, the illegal board cannot grasp the timing of occurrence of the jackpot and cannot unreasonably generate the jackpot. Thus, according to the pachinko machine 10 of the present embodiment, it is possible to prevent the occurrence of an unreasonable jackpot due to an unauthorized substrate.

  Next, a second embodiment will be described with reference to FIG. In the RAM initial value setting process of the first embodiment described above (see FIG. 28), the jackpot random number only when the values of the jackpot random number counter C1 and the random number initial value counter CINI are not within the normal range (within the update range). The upper bytes of the counter C1 and the random number initial value counter CINI are each cleared to 0. On the other hand, in the RAM initial value setting process (see FIG. 40) of the second embodiment, regardless of whether or not the values of the jackpot random number counter C1 and the random number initial value counter CINI are within the normal range, Each upper byte of CINI is cleared to 0.

  That is, in the RAM initial value setting process (S115) of FIG. 40, first, each value of the RAM 503 other than the jackpot random number counter C1 and the random number initial value counter CINI is set to an initial value (S141). Next, each upper byte of the jackpot random number counter C1 and the random number initial value counter CINI is cleared to 0 (S150). As described above, the jackpot random number counter C1 and the random number initial value counter CINI are each composed of 2 bytes, and the maximum value of the update range is 02A4h. Therefore, by clearing each upper byte to 0, the jackpot random number counter C1 and the random number initial value counter CINI are each initialized to one of 0000h to 00FFh. That is, the jackpot random number counter C1 and the random number initial value counter CINI are values within the update range of the counters C1 and CINI in accordance with the value of the lower byte of each value when the RAM initial value setting process (S115) is executed. It is initialized to one of 256 values (undefined value) from 0000h to 00FFh. After setting the initial value of each value in the RAM 503, an initialization command is transmitted to the display control device 45 (S148), and the fact that the initialization process has been executed by the main control device 261 is sent to the display control device 45, which is a peripheral control device. The RAM initial value setting process is terminated.

  Thus, also in the second embodiment, the values of the jackpot random number counter C1 and the random number initial value counter CINI can be initialized to indefinite values within the normal range in the initialization process (S114 to S115). Thus, it is impossible to grasp the values of both counters, and it is possible to prevent an unfair jackpot from being generated by an illegal board.

  Next, a third embodiment will be described with reference to FIG. In the RAM initial value setting process (see FIG. 40) of the second embodiment described above, the initialization of each value of the jackpot random number counter C1 and the random number initial value counter CINI is cleared, and the upper bytes of the counters C1 and CINI are each cleared to 0. Was done. On the other hand, in the RAM initial value setting process (see FIG. 41) of the third embodiment, the logical product of the upper byte of each counter C1, CINI and 01h is taken, and the result is the upper byte of the corresponding counter C1, CINI. By doing so, the counters C1 and CINI are initialized.

  That is, in the RAM initial value setting process (S115) of FIG. 41, first, each value of the RAM 503 other than the jackpot random number counter C1 and the random number initial value counter CINI is set to an initial value (S141). Next, the logical product of the upper byte of the jackpot random number counter C1 and 01h is calculated, and the result is used as the upper byte of the jackpot random number counter C1 (S151). Similarly, the logical product of the upper byte of the random number initial value counter CINI and 01h is obtained, and the result is used as the upper byte of the random number initial value counter CINI (S152). Since the maximum value of the update range of the jackpot random number counter C1 and the random number initial value counter CINI is 676 (= 02A4h), it is initialized to any one of 0000h to 01FFh by the logical product of the higher byte and 01h. Is done. That is, the jackpot random number counter C1 and the random number initial value counter CINI are values within the update range of the counters C1 and CINI according to the lower 9 bits of each value when the RAM initial value setting process (S115) is executed. It is initialized to any one of 512 values (undefined value) from 0000h to 01FFh. In other words, the jackpot random number counter C1 and the random number initial value counter CINI are any one of 512 types from 0000h to 01FFh, which are the results of clearing the upper 7 bits of each value when the RAM initial value setting process (S115) is executed. It is initialized to the value (undefined value).

  After setting the initial value of each value in the RAM 503, an initialization command is transmitted to the display control device 45 (S148), and the fact that the initialization process has been executed by the main control device 261 is sent to the display control device 45, which is a peripheral control device. The RAM initial value setting process is terminated. As described above, also in the third embodiment, in the initialization process (S114 to S115), the values of the jackpot random number counter C1 and the random number initial value counter CINI can be initialized to indefinite values within the normal range. Thus, it is impossible to grasp the values of both counters, and it is possible to prevent an unfair jackpot from being generated by an illegal board.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  The jackpot random number counter C1 and the random number initial value counter CINI according to the present invention are both configured as counters in which the value of the memory in the RAM 503 is updated by software control. You may make it comprise with a circuit. In such a case, if the value of the counter circuit is within the normal range (within the update range) during the initialization process (S114 to S115), the value is maintained and used without being initialized (reset). . Also, if the value of one counter circuit is within the normal range and the value of the other counter circuit is not within the normal range, the value of one counter circuit within the normal range is read out, and this is read as the other counter circuit. Write as the value of. Further, the maximum value of the normal range is 676 (= 02A4h = 0000,0010, regardless of whether the value of any counter circuit is within the normal range or the value of the counter circuit is within the normal range. 1010,0100b), the initial value of the counter circuit can be set to an indefinite value by clearing the upper 7 bits or taking out the lower 9 bits and making this the initial value of the counter circuit. It can be made to act similarly to the above-described embodiments.

  In the third embodiment, a logical operation is performed by ANDing the upper bytes of the values of the counters C1 and CINI and 01h, and the result is used as the upper bytes of the corresponding counters C1 and CINI. However, as a matter of course, such logical operation is not limited to logical product, and logical operation may be performed by logical sum, exclusive logical sum, negation, or combinational logic thereof. For example, in the third embodiment, instead of the logical product with 01h, a combination obtained by further negating the logical sum with 01h may be used.

  You may make it use this invention for game machines other than the pachinko machine 10, for example, game machines, such as a slot machine. You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after a jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special game state on the condition that a ball is awarded in a predetermined area. Further, in addition to the pachinko machine, the game machine may be implemented as various game machines such as an alepatchi, a sparrow ball, a slot machine, a game machine in which a so-called pachinko machine and a slot machine are integrated.

It is said.

  According to the gaming machine 4, the value of the second counter is updated within the same predetermined range as the counter by the second updating means. When the counter is updated by n cycles by the updating means, the initial value of the counter update is changed by the initial value changing means based on the value of the second counter updated by the second updating means. Here, when the second predetermined condition is satisfied, initialization processing is executed by the initialization unit. The initialization unit performs the second update of the value of the second counter for the initialization of the value of the second counter. A predetermined bit or a predetermined byte of all the bits or all bytes constituting the second counter is cleared so that the value is within the update range by the means. Therefore, even if the initialization process is illegally executed by the unauthorized substrate, the value of the second counter is not initialized to a specific value, like the counter value. That is, all bits or bytes other than a part of all the bits or all bytes constituting the second counter are not cleared, and the value at that time is maintained, so that the initial value depends on the value of the second counter at the time of initialization. The value of the second counter after conversion is indefinite. Therefore, it becomes impossible to grasp the values of the counter and the second counter by the illegal substrate, and the illegal act can be prevented. Note that the counter of the gaming machine 4 includes not only a counter provided on a rewritable memory updated by software control, but also a counter constituted by a hardware circuit.

By clearing from the most significant byte having a value other than 0 to the most significant byte of the counter or the second counter, a part of all the bytes constituting the counter or the second counter. The game machine 6 is characterized by clearing and initializing the value of the counter or the second counter. According to the gaming machine 6, the value of the counter or the second counter can be initialized without being set to a specific value. Note that “the most significant byte having a value other than 0 when the counter or the second counter indicates a maximum value” means that, for example, when the counter is updated from 0 to 676, the maximum value is 2A4h ( (Hexadecimal number), it means a byte having a value of 02h when the counter indicates 2A4h which is the maximum value. Therefore, when the counter is updated from 0 to 676 and the counter is composed of 2 bytes, the most significant byte which is the second byte from the lower order is cleared. When the counter is updated from 0 to 676 and the counter is composed of 4 bytes, the second to fourth bytes from the lower order to the most significant byte are cleared.

  In any of the gaming machines 1 to 4, the initialization means clears from the most significant bit of the counter or the second counter to a predetermined bit that is set when the counter or the second counter shows a maximum value. By doing this, a predetermined bit of all the bits constituting the counter or the second counter is cleared, and the value of the counter or the second counter is initialized. 7.
