Description

  The present invention relates to gaming machines represented by pachinko machines and slot machines.

  Conventionally, as a kind of gaming machine, a pachinko machine equipped with a display device for variably displaying a plurality of types of special symbols and the like in a predetermined arrangement is known. In this type of gaming machine, for example, a special symbol is displayed on the display device on the basis of the winning of a ball at a starting port composed of an electric tulip or the like, and a stop mode (stop symbol) when the special symbol is stopped is displayed. Accordingly, a special gaming state (a jackpot state) can be derived.

  In addition, in the gaming machine configured as described above, when a ball is won at the start opening during execution of the variable display on the display device, in order to prevent the player from being disadvantaged, The lottery result of the internal lottery based on the above is stored in a memory or the like with a predetermined number (for example, 4) as an upper limit, is kept waiting until the variable display during execution ends, and stored when the variable display during execution ends The variable display based on the lottery result of the internal lottery stored in the memory and waiting is executed in the order of waiting.

Further, in such a gaming machine, a variable display is performed using a symbol called a normal symbol in addition to a special symbol that generates a special gaming state, and a stop result (display result) of the normal symbol is displayed in advance. When the electric tulip is in the open state, the electric tulips arranged on both sides of the starting opening are in an open state, and the ball is easily put into the starting opening with the opening of the electric tulip. ing.

  However, in such a gaming machine, for example, even if a ball wins a winning opening when the number of standby times for variable display is the upper limit, only the winning ball is paid out and the variable display based on the winning is not waited. On the other hand, even if there is no variable display waiting number, the open mode of the electric tulip is constant, so if the normal symbol variable display is won and the electric tulip is in the open state, the game ball wins the starting opening. Even if it becomes easy, the change display is not executed unless the game ball wins the starting opening. Accordingly, there is a problem in that the variation display execution state varies, and the variation display is not executed, thereby causing the player to feel dissatisfied with the game.

  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 a 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 prize opening 31, the variable prize winning device 32, and the big game mouth 33 and a predetermined output is made from a big game mouth switch 33a described later, the upper game 19 (or the lower plate 15) is entered. A predetermined number of prize balls are paid out. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like are guided through the out port 36 to a ball discharge path (not shown). The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (acts) such as a windmill.

  The variable display device unit 35 includes a small symbol display unit 42b that displays a small symbol in a display area in a part of the display area as a trigger, and a game ball to the big mouth 33 in another display area. And a symbol display device 42 including a large symbol display unit 42a that variably displays a special symbol by using the winning of the prize. The accessory symbol display unit 42b is provided with two display areas for accessory symbols and has a holding display unit (not shown). Each time a game ball passes through the accessory gate 34 and is detected by an accessory port switch 34a described later. In the accessory symbol display unit 42b, when the display symbol (for example, “○” and “x” accessory symbol) fluctuates and the variation display stops at a predetermined symbol (small hit. For example, “◯◯”), Tulips (movable pieces) 33b disposed on the left and right of the big mouth 33 are configured to be activated (opened) for a predetermined time. As the tulip 33b is opened, the number of paths through which the game ball wins the big game mouth 33 increases, so that the game ball easily wins the big game mouth 33. The tulip 33b is connected to a tulip drive solenoid 33c, which will be described later, and is configured to open and close in the left-right direction as the tulip drive solenoid 33c is driven. The number of times the game ball passes through the accessory gate 34 is held up to a maximum of 4 times, and the number of times of holding is lit and displayed on a hold display section (not shown). In addition, the variable display of the small symbols is performed by using a part of the symbol display device 42 (liquid crystal display device) as in this embodiment, and the variable display device unit 35 is provided with a plurality of lamps and the like. You may make it carry out by switching lighting of this some lamp | ramp. Similarly, lighting of a holding display unit (not shown) may be performed by a lamp or the like provided in the variable display device unit 35.

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

  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 the big game mouth 33, the big game symbol display unit 42a displays the symbols in a variable manner, and the special game is based on the requirement that the final symbol combination after the stop is 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. Four hold lamps 46 corresponding to the maximum number of holds are provided, and are arranged above the 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 symbol display device 42.

  In the conventional pachinko machine, there are provided a plurality of types of opening modes of the tulip 33b when a small hit occurs in the small symbol variation display, and the opening mode of the tulip 33b in the non-stochastic variation state (that is, the normal gaming state). Accordingly, the opening mode of the tulip 33b in the probability variation state is configured to be in an advantageous state for the player. Specifically, by increasing the opening time or the number of times of opening of the tulip 33b in the probability variation state small hitting time than in the normal gaming state small hitting time, the ball in the probability variation state is larger than the normal variation state. It is configured to make it easy to win a prize in the mouth 33.

  However, in such a pachinko machine, during the probability variation state, the tulip 33b is configured to be opened longer than in the normal gaming state, depending on whether or not the small symbol variation display is waiting, regardless of the number of standby times of the large symbol variation display. At the same time, the variation time of the large game symbol variation display is shorter than the variation time of the normal gaming state. In the pachinko machine configured in this way, for example, even if a ball wins the big game mouth 33 when the upper limit of the number of waiting times for display of a large symbol is displayed, only the winning ball is paid out and based on the winning The large symbol design is not waited for. On the other hand, even when there is no waiting display for the large symbol variation display, the opening mode of the tulip 33b is constant. If there is no winning, the variable display is not executed. That is, during the probability variation state, the variation display of the large symbol that has been waiting is quickly digested as the variation time of the large symbol is shortened, and the large symbol display unit 42a does not execute the variation display of the large symbol. There was a case. In this way, during the probability variation state where it is easier to win the big game mouth 33 than in the normal gaming state, if the large symbol design variation display, which is a jackpot lottery opportunity that can generate a great profit to the player, is not executed, There is a problem in that the player who recognizes that the change display is easily executed is caused to feel dissatisfaction with the game.

  Further, at the design stage of the pachinko machine 10, when a game ball wins the big game mouth 33, a probability of winning a jackpot is set as a predetermined number of prize balls to be paid out. However, the actual pachinko machine 10 has an upper limit on the number of times of waiting for variable display, and when the number of pending variable displays is the upper limit, only the winning ball is paid out when a game ball is awarded to the big mouth 33. , Fluctuation display based on the winning is not suspended (waiting). Therefore, since the variable display based on the start winning prize is not executed when the number of the variable display hold is the upper limit, the player suffers a disadvantage when compared with the winning ball ratio set at the design stage. I will let you.

  Therefore, in the pachinko machine 10 according to the present embodiment, the opening time or the number of times of opening of the tulip 33b is determined according to the determination result of the probability variation state or the normal gaming state and the determination result of the standby count of the large symbol variation display. Is configured to change. Specifically, the tulip 33b is opened for approximately 4.5 seconds in a situation where the change display of the large symbol is waited less than three times during the probability change state. On the other hand, the tulip 33b is released for approximately 0.5 seconds in a situation other than the above situation, that is, in a situation where a large symbol variation display is waited three times or more during the normal gaming state and the probability variation state. By configuring in this way, the tulip 33b can be opened for a long time so that a ball can easily win a big game mouth 33 in a situation where the number of waiting times for display of a large symbol symbol during a probability variation state is small. In the middle game, the large symbol display unit 42a can avoid the non-execution state of the large symbol variation display as much as possible, and can stably execute the large symbol variation display. Therefore, it is possible to solve the problem that the player who recognizes that the ball is more likely to win the big game mouth 33 in the probability variation state than the normal game state is caused to feel dissatisfaction with the game.

  Further, in the pachinko machine 10 according to the present embodiment, the opening mode of the tulip 33b is changed as necessary, that is, in the probability variation state where the variation display is digested earlier than the normal state, and the number of variation displays in standby is It is configured to open longer than the normal gaming state only in the situation of less than 3. Therefore, the start time of the tulip 33b is set longer than the normal gaming state only when the display of the variation of the large-sized symbol on standby is likely to be eliminated and the variation display is not executed on the large-sized symbol display device 42. When the necessity for winning is high, it is possible to easily generate a start winning. Therefore, since it is possible to make it easy to execute the large symbol variation display without changing the prize ball ratio of the pachinko machine 10, it becomes easier to execute the large symbol variation display than necessary, thereby realizing the above effect. The problem of causing the player to feel dissatisfied with the game can be solved without causing any disadvantage to the hall (game hall) side where the pachinko machine 10 is installed.

  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 the game launched by the turning operation of the game ball launch handle 18. The ball is 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 firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball launched in accordance with the turning operation of the game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path of the rail unit 50 as described above. Is done.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded as compared with the prior art. However, under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than that of the existing one to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launching device can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 61 is formed so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area.

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

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

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

  Further, the game ball launching device is provided with a 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-emitting mode by turning on or flashing according to the change in 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 incorporating a light emitting means such as an LED. 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. In a state where the front frame set 14 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide rail. Thereby, the collision of the game ball with the glass 137 can be prevented in most sections of the guide rail. Therefore, adverse effects such as breakage due to contact with the glass 137 can be suppressed.

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

  Further, the rail cover 140 is formed with a ridge 142 extending in an arc shape along the inner edge thereof and projecting toward the front side of FIG. When the front frame set 14 is closed, the protrusion 142 is configured to overlap the inner rail portion 51 substantially integrally with the protrusion 142 entering the guide rail. Therefore, for example, even if a wire or the like is 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.

The reason why the ny latch is not used for the fixing tool 242 and the locking hole 387 is that a tank 355 for storing game balls is provided on the left side of the locking hole 387 in FIG. is there. When the fixture 242 is fixed, the back pack unit 203 is also fixed to the inner frame 12 by the fixtures 241 and 243 shown in FIG. The support hole 238 and the support shaft 385 are in the support shaft portion M6 in FIG. 8, the fastened hole 240 and the ny latch 386 are in the fastening portion M7, and the fixture 242 and the lock hole 387 are in the lock portion M8, respectively. Equivalent to. Further, the fixture 243 corresponds to the locking portion M9.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. The main controller 261 is equipped with an MPU 501 as a one-chip microcomputer that is an arithmetic unit. The MPU 501 stores various control programs executed by the MPU 501, fixed value data, ROM 502 storing variation pattern determination tables 502 a and 502 b, and various data when executing the control program stored in the ROM 502. In addition, a RAM 503, which is a memory for temporary storage, and various other circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The ROM 502 is provided with a large variation pattern determination table 502a that stores a variation pattern of a special symbol (large symbol) and a small variation variation determination table 502b that stores a variation pattern of a normal symbol (small symbol). Yes.

  Here, with reference to FIG. 26, the large object variation pattern determination table 502a and the small object variation pattern determination table 502b will be described. FIG. 26A is a diagram schematically illustrating the configuration of the large object variation pattern determination table 502a, and FIG. 26B is a diagram schematically illustrating the configuration of the accessory variation pattern determination table 502b.

  The big game variation pattern determination table 502a is a table that stores a variation pattern of a large game symbol display performed by the big game symbol display unit 42a. When a game ball enters the big game mouth 33, this big game variation pattern is determined. A large symbol variation pattern to be executed by the large symbol display unit 42a is determined with reference to the determination table 502a and various counters to be described later. In the pachinko machine 10 of the present embodiment, a total of 34 variation patterns are set as variation patterns, including 16 types of “normal reach”, 16 types of “super reach”, and 2 types of “loss variation”. . First, each of these variation patterns will be described in order.

  Loss fluctuation is a pattern in which the display result of the loss is displayed without the reach display, and “variation loss 1 (shortening)” and “loss loss fluctuation” are set in two types of fluctuation time required from the start to the stop of the fluctuation. 2 (normal) ”. “Lose variation 1” is a loss variation performed at a variation time of 5 seconds. When this “lack variation 1” is selected as a variation pattern, the left middle right symbol sequence displayed on the large symbol display unit 42a. After starting the change, the change in the left symbol sequence is stopped 3 seconds later, the change in the right symbol sequence is stopped 1 second later (4 seconds after the start of change), and another 1 second later (change start) 5 seconds later), the fluctuation of the middle symbol row is stopped, and the display result of the fluctuation display appears. Here, the variation pattern means each form in the case where features having common features of variation display are divided. In this embodiment, whether or not a pattern variation time is accompanied with a specific symbol. It is assumed that the mode of variation including the above is defined. During the fluctuation display, even if the fluctuation pattern is the same, the display control device 45 controls to change the previous fluctuation display display result (stop symbol) and the stop symbol after fluctuation for each variation display. The symbols are scrolled and displayed on the big symbol display portion 42a.

  The “loss variation 2” is a loss variation performed with a variation time of 11 seconds, and the time until the left symbol sequence stops varying is set longer than the “loss variation 1”. In “Loss fluctuation 2”, the left symbol sequence stops changing after 9 seconds from the start of the variation, the right symbol sequence stops after 1 second, and the middle symbol sequence stops after 1 second. Display the display result of losing without reach display. One of the “loss variation 2” and the “loss variation 1” is selectively selected according to the number of variation displays in standby. Specifically, only when there are two or more changes in the display of the large symbol that is waiting at the start of the change, the “loss variation 1” with a short variation time (5 seconds) is selected, and the change in the large symbol that is waiting When the display is “1” or less, “loss variation 2” is selected.

  Here, in the state where the number of times of waiting for the variable display (the number of balls to be held) is the maximum four times, even if there is a winning at the symbol operating port 4, the winning cannot be held and is a useless start winning for the player. Therefore, in the pachinko machine where the start winning is likely to occur, it is required to shorten the fluctuation time. On the other hand, if the variation display is too short and the variation display is interrupted, the expectation of the jackpot will not be maintained and the player's willingness to play will be attenuated, so an appropriate variation time is also required. According to the pachinko machine 10 of the present embodiment, a variation pattern with a short variation time is selected only when the standby variation display is equal to or greater than a predetermined number (“2” in the present embodiment). In addition, it is possible to prevent the change display from being interrupted and the game motivation from being attenuated while digesting the change display during standby and suppressing unnecessary start winnings.

  “Normal reach 1” to “Normal reach 16” (hereinafter abbreviated as “normal reach” where appropriate) are so-called normal reach patterns with reach display. 1 second later (10 seconds after the start of fluctuation), the fluctuation of the right symbol sequence is stopped and the reach display is displayed, and then the symbol sequence in the following is scrolled until the variation time for each pattern is reached. Stop. The mode from when the reach display appears until the middle symbol sequence stops scrolling is different for each pattern, with a pattern that stops at a low speed for a certain period of time without any special change, Then, after the fluctuation speed is decelerated step by step in one or two stages, the fluctuation is stopped.

  “Super Reach 1” to “Super Reach 16” (hereinafter abbreviated as “Super Reach” as appropriate) has a longer performance time than normal reach and displays character designs such as “fish school” and “bubbles” on the large symbol display unit 42a. It is a so-called super reach pattern. In these patterns, the fluctuation of the left symbol row is stopped 9 seconds after the start of the fluctuation display, and the fluctuation of the right symbol row is stopped after one second (10 seconds after the fluctuation starts) and reach display is performed. And then scroll the symbol sequence until the variation time for each pattern (maximum 30 seconds) is reached and stop. That is, the fluctuation time required for the fluctuation display of one large symbol is set to a maximum of 40 seconds. During this scrolling, a specific display such as a character design (for example, a school of fish or bubbles) set for each pattern or a background display (for example, a blue background is changed to a rainbow color at normal times) is accompanied. Make it. After the character symbols and the like constituting this super reach appear, the player shifts to a jackpot at a high ratio, and the player has a sense of expectation for the jackpot due to the appearance of the character symbols and the like.

  The big game variation pattern determination table 502a used for selecting each variation pattern described above generates a jackpot table and a jackpot table for determining a variation pattern for variation display that generates a jackpot based on the value of a jackpot random number counter C1 described later. It is composed of a loss reach table for determining a variation pattern of variation display that is not to be performed. The lose reach table is for determining the change pattern of the change display won in the lottery execution lottery.

  In the jackpot table, the value of the variation type counter CS1 is divided with respect to the variation pattern with reach display. Specifically, the value of the variation type counter CS1 updated within the range of “0 to 255” is “0 to 31” for “normal reach” and “super reach” as shown in FIG. Thus, the variation patterns of “normal reach” and “super reach” are divided into a ratio of 1: 7. In the lose reach table, the value of the fluctuation type counter CS1 is divided into “0 to 223” for “normal reach” and “224 to 255” for “super reach”. The variation pattern of “reach” is divided into a ratio of 7: 1.

  “Normal reach” and “super reach” are both fluctuation patterns with reach display, and are executed only when either the jackpot table or the lose reach table is used for selection of the fluctuation pattern. Both tables are used only when winning a jackpot lottery or a lottery lottery, so if a variation pattern with reach display is selected, a fluctuation display that expects a transition to a jackpot (expected fluctuation) ) Is performed, the player can be expected to generate a big hit by the appearance of the reach display. On the other hand, in a variable display (unfavorable fluctuation) without a reach display, a jackpot cannot occur, and the player cannot have a sense of expectation for the jackpot. In addition, you may provide the pattern which generate | occur | produces jackpot with the fluctuation pattern which does not accompany reach display. For example, a variation pattern may be provided in which a jackpot display result appears after a symbol variation is performed again after separate symbols stop in the middle left and right without reach display. The unfavorable fluctuation means a fluctuation without a specific display that expects a transition to jackpot, and the unfavorable fluctuation may cause a jackpot display result to appear.

  In addition, the “normal reach” is selected with a higher ratio of the loser reach table than the jackpot table, while the “super reach” is selected with a higher ratio of the jackpot table than the loser reach table. For this reason, when “Super Reach” is selected as the variation pattern, it will shift to jackpot at a higher rate than “Normal Reach”, and the player will be able to see the character designs that make up Super Reach. You can have a sense of expectation for the big hit.

  In each table described above, 1 byte value indicating 34 variation patterns from “01h” to “22h” is set for each variation pattern, and these 34 values correspond to the value of the variation type counter CS1. And stored in each table. At the start of fluctuation, a value indicating the fluctuation pattern in each table is acquired based on the value of the fluctuation type counter CS1, and is set as the lower byte of the big game fluctuation pattern command for specifying the fluctuation pattern. Each table is assigned a value of the variation type counter CS1 for each 1-byte value indicating each variation pattern in “normal reach” and “super reach”. In FIG. 26, the reach is shown for ease of understanding. The values of the variation type counter CS1 are collectively shown for each type.

  Here, a control command transmitted from the main control device 261 to the display control device 45 in order to control a large-size symbol variation display will be described. The control command for the large-size symbol change display is constituted by a large-size variation pattern command, a large-size stop symbol command, and a large-item confirmation command. Each control command is composed of 2 bytes, and the upper 4 bits of the first byte are used as bits for identifying each command. At the start of a large symbol variation, a large variation pattern command for designating a series of variation patterns from the start to the end of the variation display, and a large stop symbol command for indicating a large symbol stop symbol are displayed in the large symbol variation display. It is transmitted to the display control device 45 as a display command for instructing the contents. In addition, when the large symbol change is stopped, the large symbol confirmation command is transmitted to the display control device 45, and the left middle right symbol of the large symbol display unit 42a is fixed and stopped as a display result of the large symbol variation display. If there is data for variable display of the waiting large symbol after transmitting the large item confirmation command to the display control device 45, the large symbol variation pattern command and the large game stop symbol command are transmitted to the display control device 45 according to the data. It is configured to be.

  Note that the value of the variation type counter CS1 does not necessarily have to be divided into the ratios set in the above-described large variation pattern determination table 502a, and may be divided into other ratios. Further, the variation pattern is not necessarily limited to the type described above, and may be set as a smaller pattern or more patterns than those described above.

  The accessory variation pattern determination table 502b shown in FIG. 26 (b) is a table that stores a variation pattern of a variation display of a large symbol performed in the accessory symbol display unit 42b, and when the game ball passes through the accessory gate 34. Furthermore, the accessory symbol variation pattern executed by the accessory symbol display unit 42b is determined with reference to the accessory variation pattern determination table 502b and a gaming state such as a probability variation state in which a big hit is likely to occur. In the pachinko machine 10 of the present embodiment, three types of variation patterns are set as the variation patterns of the accessory symbol. First, each of these variation patterns will be described in order.

  The “normal variation pattern” is a pattern that is set in a normal gaming state, that is, a gaming state that is not a probability variation state regardless of whether the accessory symbol is correct or not. ing. When this “normal variation pattern” is selected as the variation pattern, the accessory symbols displayed in the left and right display areas 42b1 and 42b2 of the accessory symbol display unit 42b start to change, and both display areas 42b1 30 seconds after the start. , 42b2 is stopped, and the display result of the change display of the accessory symbol appears.

  The “shortened variation pattern” is a pattern that is set in the probability variation state regardless of whether or not the accessory symbol is correct. The variation time required from the start to the end of the variation is set to 5 seconds, and the variation time is much longer than in the normal gaming state. Has been shortened to. When this “shortening variation pattern” is selected as the variation pattern, the accessory symbols displayed in the left and right display areas 42b1 and 42b2 of the accessory symbol display unit 42b start to change, and both display areas 42b1 after 5 seconds from the start. , 42b2 is stopped, and the display result of the small symbol variation display appears.

  In the accessory variation pattern determination table 502b, a 1-byte value indicating two variation patterns of “01h” and “02h” is set for each variation pattern. At the start of variation, a value indicating any variation pattern is acquired according to the gaming state, and is set as a lower byte of the accessory variation pattern command for designating the variation pattern.

  Here, a control command transmitted from the main control device 261 to the display control device 45 in order to control the small symbol variation display will be described. The control command for displaying the change of the accessory symbol includes an accessory variation pattern command, an accessory stop symbol command, and an accessory confirmation command. Each control command is composed of 2 bytes, and the upper 4 bits of the first byte are used as bits for identifying each command. At the start of small symbol variation, the small symbol variation pattern command for designating a series of variation patterns from the start to the end of the variation display and the small symbol stop symbol command indicating the small symbol stop symbol are displayed in the small symbol variation display. It is transmitted to the display control device 45 as a display command for instructing the contents. In addition, when the accessory symbol variation is stopped, an accessory confirmation command is transmitted to the display control device 45, and the symbols on the left and right of the accessory symbol display unit 42b are confirmed and stopped as a display result of the accessory symbol variation display. After transmitting the accessory confirmation command to the display control device 45, if there is data for variable display of the waiting accessory symbol, the accessory symbol variation pattern command and the accessory stop symbol command are transmitted to the display controller 45 in accordance with the data. It is configured to be.

  Returning to FIG. The RAM 503 of the main controller 261 has a configuration in which the backup voltage is supplied from the power supply device 313 even after the power of the pachinko machine 10 is shut off, and data can be retained (backed up). In addition to the memory and area for temporary storage, a backup area 503a, a probability variation flag 503b, and a reserved ball counter 503c are provided.

  The backup area 503a stores values such as a stack pointer, each register, I / O, etc. when the power is shut down (including when a power failure occurs, the same applies hereinafter) when the power is shut off due to the occurrence of a power failure or the like. When the power is turned on (including power-on due to power failure cancellation, the same applies hereinafter), the state of the pachinko machine 10 is restored to the state before power-off based on the information in the backup area 503a. Writing to the backup area 503a is executed when the power is shut off by the NMI interrupt process (see FIG. 36), and restoration of each value written in the backup area 503a is executed in the main process (see FIG. 27) when the power is turned on. . Note that the power failure signal SG1 from the power failure monitoring circuit 542 is input to the NMI terminal (non-maskable interrupt terminal) of the MPU 501 when the power is interrupted due to the occurrence of a power failure or the like. Is input immediately, the NMI interrupt process as a power failure process is immediately executed.

  The probability variation flag 503b is a flag for determining whether or not the gaming state after the jackpot game ends is a probability variation state in which a jackpot is more likely to occur than in the normal gaming state. The probability variation flag 503b is a value for generating a jackpot when a value of a jackpot random number counter C1 (described later) written in an effect execution area (not shown) of a storage area for storing a retaining ball (described later) and a jackpot symbol counter C2 (described later). When the value of is a value indicating an odd number of symbols, it is configured to be turned on at the end of the large symbol variation display based on the data stored in the effect execution area. On the other hand, the probability variation flag 503b is a value that causes the jackpot random number counter C1 written in the effect execution area to generate a jackpot and the value of the jackpot symbol counter C2 is a value that indicates an even number of symbols. It is configured to be turned off at the end of the variation display of the big game symbol based on the data stored in the effect execution area.

  The reserved ball counter 503c is a counter that stores a value corresponding to the number of standby times (the number of held balls) for displaying a large symbol as variable number information. The value of the holding ball counter 503c is incremented by “1” when a game ball wins the big game mouth 33 (start winning prize), while every time the value of the holding ball storage area to be described later is shifted. 1 "is subtracted by one. In addition, the value of the reserved ball counter 503c is displayed when the large symbol display is not displayed on the large symbol display unit 42a or when the large symbol variation is displayed, but there is no pending large symbol variation display. "0" in the case, "1" if the change display of the pending large figure is 1 time, ..., "4" if the change display of the pending large figure is 4 times . In the pachinko machine 10 according to the present embodiment, since the maximum number of standby times for displaying a large symbol is four, the value of the reserved ball counter 503c is configured to change within a range of “0” to “4”. Has been. Furthermore, in accordance with the value of the holding ball counter 503c, data related to the display of fluctuations in large symbols based on the start winning (such as a big hit random number counter C1 described later) is written and stored in a holding ball storage area described later. Has been. In this embodiment, when the value of the holding ball counter 503c is “4” and the game ball wins the big game mouth 33, the start winning prize is ignored and the value of the holding ball counter 503c is ignored. Are not added, and writing of data relating to a large symbol symbol display is prohibited in the reserved ball storage area.

  The pachinko machine 10 of the present embodiment is configured to change the opening time or the number of times of opening of the tulip 33b according to the on / off state of the probability variation flag 503b and the value of the reserved ball counter 503c. Specifically, when the probability variation flag 503b is turned on and the value of the holding ball counter 503c is less than “3”, that is, during the probability variation state, the large symbol variation display waits less than three times. In this situation, the tulip 33b is opened for approximately 4.5 seconds. On the other hand, the probability variation flag 503b is turned off, or the probability variation flag 503b is turned on and the value of the holding ball counter 503c is “3” or more, that is, the probability that the normal gaming state is being established The tulip 33b is released for approximately 0.5 seconds in a situation where the display of the change of the large symbol is waited three times or more during the change state. By configuring in this way, the tulip 33b can be opened for a long time so that a ball can easily win a big game mouth 33 in a situation where the number of waiting times for display of a large symbol symbol during a probability variation state is small. In the middle game, the large symbol display unit 42a can avoid the non-execution state of the large symbol variation display as much as possible, and can stably execute the large symbol variation display. Therefore, it is possible to solve the problem that the player who recognizes that the ball is more likely to win the big game mouth 33 in the probability variation state than the normal game state is caused to feel dissatisfaction with the game.

  Further, in the pachinko machine 10 according to the present embodiment, the opening mode of the tulip 33b is changed as necessary, that is, in the probability variation state where the variation display is digested earlier than the normal state, and the number of variation displays in standby is It is configured to open longer than the normal gaming state only in the situation of less than 3. Therefore, the start time of the tulip 33b is set longer than the normal gaming state only when the display of the variation of the large-sized symbol on standby is likely to be eliminated and the variation display is not executed on the large-sized symbol display device 42. When the necessity for winning is high, it is possible to easily generate a start winning. Therefore, since it is possible to make it easy to execute the large symbol variation display without changing the prize ball ratio of the pachinko machine 10, it becomes easier to execute the large symbol variation display than necessary, thereby realizing the above effect. The problem of causing the player to feel dissatisfied with the game can be solved without causing any disadvantage to the hall (game hall) side where the pachinko machine 10 is installed.

These sub-designs are made up of pictorial symbols, and each of these main symbols and sub-designs constitutes a large symbol design. 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. In the large symbol display section 42a, large symbols are displayed in three stages of upper, middle, and lower for each symbol row. Accordingly, a total of nine large symbols in three rows × three columns are displayed on the large symbol display portion 42a. The large symbol display portion 42a 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 the left symbol row → the right symbol row → the middle symbol row, 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.

  In the accessory symbol display unit 42b, symbols are displayed in the left and right display areas 42b1 and 42b2, and a symbol “O” or “X” is displayed in each of the display areas 42b1 and 42b2. It is configured. In the small symbol variable display, when the symbol “◯” is confirmed and displayed in both the display areas 42b1 and 42b2, a small hit is made, and the tulip 33b is driven to open a predetermined number of times according to the gaming state. More specifically, the small hit in the normal gaming state is configured to execute the driving for opening the tulip 33b for 0.5 seconds only once, while the small hit in the probability variation state is 1. The opening drive of the tulip 33b for 0 second is performed three times.

  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 symbol display device 42, and the like. Specifically, FIG. As shown in the figure, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selecting the jackpot symbol for the variation display of the big game symbol, and the reach lottery when the variation display of the big game symbol is changed. Reach random number counter C3 to be used, random number initial value counter CINI to be used for setting the initial value of jackpot random number counter C1, variation type counters CS1 and CS2 to be used for variation pattern selection for variation display of large symbols, left column, middle Using left, middle, and right out symbol counters CL, CM, and CR used to set each out symbol in the row and right column It is set to be. In addition, the accessory symbol random number counter C4 is used for the lottery display of the accessory symbol variation display.

  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), and in each of these areas, game balls to the big game mouth 33 are provided. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in accordance with the winning timing.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated within the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once every timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment), and the stored ball in the RAM 503 is stored according to the value of the held ball counter 503c at the timing when the game ball wins the big game mouth 33. Stored in the area. There are two types of random numbers that are jackpots: normal gaming state (low probability) and probability variation state (high probability). The number of random number values that are jackpots in normal gaming state Is 2, and its value is “337, 673”, the number of random numbers that are jackpots in the probability variation state is 10, and its value is “67, 131, 199, 269, 337, 401, 463, 523” , 601, 661 ”. In the probability variation state, the combination of big symbols is a big hit by a predetermined probability variation combination, and the subsequent jackpot probability is increased as an added value (in this embodiment, after the jackpot of odd symbols is finished) (Game state) means the time of so-called probability change, and the normal game state (low probability) means the time when it is not such a probability change state.

  The jackpot symbol counter C2 determines the symbol at the time of the fluctuation stop of the variation display of the big symbol symbol in the case of the jackpot. In the present embodiment, the big symbol symbol display unit 42a has five effective lines, and the specific symbol 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 this embodiment), and the stored ball in the RAM 503 is stored according to the value of the held ball counter 503c at the timing when the game ball wins the big game mouth 33. Stored in the area.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by one before and after the reach symbol. Similarly, after the reach has occurred, the final stop symbol is the reach symbol. “Reach other than front / rear off” that stops other than before and after, and “completely out” that does not occur reach will be drawn. 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 state of the big hit lottery probability of the variation display of the big game symbol, the number of suspended balls at the start of the variation, and the like. The reach random number counter C3 is periodically updated (once every timer interruption in the present embodiment), and the stored ball in the RAM 503 is stored according to the value of the held ball counter 503c at the timing when the game ball wins the big game mouth 33. Stored in the area.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented by 1 in order within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”.

  The first variation type counter CS1 determines the reach type of a large symbol such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (book) In the embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the variation of the large symbol is started by the large symbol display unit 42a.

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

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

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

  The accessory symbol random number counter C4 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The accessory symbol random number counter C4 is updated periodically (once every timer interruption in this embodiment), and the game ball passes through one of the accessory gates (through gates) on the left and right and is detected by the accessory port switch 34a. Get when it is done. The number of random number values to be won is 149, and the winning range is “5 to 153” regardless of the gaming state.

  Next, each control process executed by the MPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. The processing of the MPU 501 is roughly divided into a main processing that is started when the power is turned on, and a timer interrupt processing that is started periodically (in the present 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 is performed. explain.

  FIG. 34 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 501 of the main controller 261 every 2 ms, for example. In the timer interruption process, first, reading processes of various winning switches are executed (S601). That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI is updated (S602). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the accessory symbol random number counter C4 are updated (S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the accessory symbol random number counter C4 are each incremented by 1 and their counter values are the maximum values (in this embodiment, 676, 49, respectively). , 238, 250), each is cleared to 0. Then, the updated values of the counters C1 to C4 are stored in the corresponding buffer area of the RAM 503. After that, a start winning process is performed in accordance with winning in the big mouth 33 or the small gate 34 (S604).

  This start winning process will be described with reference to the flowchart of FIG. First, it is determined from the detection information of the big mouth switch 33a whether or not the game ball has won (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), the number N of the active game holding balls for the large symbol symbol display, that is, the value of the holding ball counter 503c is the upper limit value (4 in this embodiment). ) Is determined (S702). If there is a prize at the big mouth 33 and the number of reserved balls (reserved ball counter 503c value) <4 (S702: Yes), the number of retained operating balls N (value of the reserved ball counter 503c) is incremented by one. (S703) Further, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the reserved area of the reserved ball storage area of the RAM 503 indicated by the value of the reserved ball counter 503c. Store (S704), and the process proceeds to S705. 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, the number N of activated balls (the value of the holding ball counter 503c) <4 (S702: No), each process of S703 and S704 is skipped, and the process proceeds to S705.

  In the process of S705, it is determined from the detection information of the accessory port switch 34a whether or not the game ball has passed through the accessory gate 34 (S705). If it is determined that the game ball has passed through the accessory gate 34 (S705: Yes), it is determined whether or not the number M of active suspension balls of the accessory symbol variation display is less than the upper limit value (4 in the present embodiment). (S706). If there is a prize for the accessory gate 34 and the number of the operation-reserved balls M <4 (S706: Yes), 1 is added to the number of the operation-reserved balls M (S707), and the accessory design random number updated in the step S603. The value of the counter C4 is stored in the accessory symbol random number counter buffer (S708), and this start winning process is terminated. On the other hand, if there is no winning at the small gate 34 (S705: No), or even if there is a winning at the small gate 34, if the number of suspended balls M <4 is not satisfied (S706: No), each of S707 and S708 Processing is skipped and this 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 by the big game symbol display unit 42a is started accordingly, but after the start winning game, 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 variation pattern of a large symbol, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses).

  FIG. 36 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. 36 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main control device 261 can be executed, and the NMI interrupt processing is executed within this predetermined time.

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

  The above NMI interrupt process is executed in the same manner 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 control device 311 and the MPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 36 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 27 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, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (audio lamp control device 262, payout control device 311, etc.) to become operable, Wait processing (for example, about 1 second) is executed. 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). If it is turned on (S104: Yes), the process is performed to clear (erase) the backup data. The process proceeds to S114. On the other hand, if the RAM erasure switch 323 is not turned on (S104: No), it is further determined whether or not the information on occurrence of power interruption is stored in the backup area 503a of the RAM 503 (S105). (S105: No), since backup data is not stored, in this case as well, the process proceeds to S114. If the 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, for example, a checksum value at the work area address of the RAM 503. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 503 is correctly stored.

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

  On the other hand, if the RAM erasure switch 323 is not turned on (S104: No), the information on the occurrence of power shutdown is stored (S105: Yes), and the RAM judgment value (checksum value etc.) is normal ( (S107: Yes), the process proceeds to S108, and a process at the time of power recovery (a process at the time of power-off restoration) 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.

  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, for example, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. In addition, 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 is displayed by the large symbol symbol display unit 42a. In addition, after the start of large symbol variation, one each time in the normal processing in the order of variation pattern command → stop symbol command of the left symbol sequence → stop symbol command of the middle symbol sequence → stop symbol command of the right symbol sequence (i.e. A command is transmitted (one every 4 ms), and a confirmation command is transmitted at the end of the fluctuation time.

  Next, each value of the variation type counters CS1 and CS2 is updated (S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503. Further, the off symbol counters CL, CM, and CR of the left symbol row, the middle symbol row, and the right symbol row are updated by the off symbol counter updating process (S203).

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

  In updating outlier symbol counters CL, CM, and CR in 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 out to be the current value of the symbol counters CL, CM, CR. According to the update process of CL, CM, CR, the outlier counters CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row are sequentially updated one by one in one normal process. The update time of each counter value does not overlap. Thus, every time the normal process is executed three times, the set symbol counters CL, CM, and CR are updated for one set.

  Thereafter, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination (S306). If the symbol combination is a jackpot symbol combination (S306: Yes), this process 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 back-and-forth outreach. 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 a combination of reach other than front / back off (S308: No), the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503 (S310). ). If the combination of the out symbol counters CL, CM, CR is not a combination of the jackpot symbol (S306: No) and not the combination of the reach symbol (S307: No), the combination of the out symbol counters CL, CM, CR is out of symbol. In such a case, the combination of the off symbol counters CL, CM, and CR is stored in the complete off symbol buffer of the RAM 503 (S311).

  After completion of the off symbol counter CL, CM, CR update processing (S203), the process returns to the normal processing of FIG. 28, reads the prize ball count signal and the payout abnormality signal received from the payout control device 311 (S204), A large symbol variation process for performing variation display of a large symbol by the symbol display unit 42a is executed (S205). By this big game symbol variation process, a big hit determination, a 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, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 32 is executed in the case of the big hit state (S206). That is, the big winning opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening has elapsed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Next, display control of the accessory symbol (for example, “O” or “x” ordinary symbol) by the accessory symbol display unit 42b is executed (S207). Briefly, on the condition that the game ball has passed through the accessory gate (through gate) 34, the value of the accessory symbol random number counter C4 is acquired and the accessory symbol display unit 42b displays the variation of the accessory symbol. Is implemented. Then, a small symbol drawing is performed based on the value of the small symbol random number counter C4, and when the small symbol wins, the electric tulip attached to the big mouth 33 is opened for a predetermined time. Details of the accessory symbol control process will be described later.

  Thereafter, it is determined whether or not the execution timing of the next normal process 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 above-described processes after S201 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 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, by repeatedly updating the random number initial value counter CINI using the remaining time, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random. Similarly, The variation type counters CS1 and CS2 can also be updated at random.

  Next, the 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 the jackpot game displayed on the big symbol display unit 42a and the middle of a predetermined time after the jackpot game ends. 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 design is being displayed by the large symbol display unit 42a (S402). If the large symbol design is not being displayed (S402: No), It is determined whether or not the number N of actuated suspended balls (the value of the retained ball counter 503c) of the large object symbol display is greater than 0 (S403). If the number N of activated balls to be held (the value of the held ball counter 503c) is 0 (S403: No), this processing is terminated as it is. If the number N of working balls (the value of the holding ball counter 503c))> 0 (S403: Yes), the number N of working balls (the value of the holding ball counter 503c) is decremented by 1 (S404), and the holding ball storage area The data stored in is shifted (S405). This data shift process is a process for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area. After the data shift process, the big symbol change start process of the big symbol is executed (S406). The big shot change start process will be described later.

  In the process of S402, when the large symbol design is being displayed (S402: Yes), it is determined whether or not the variation time has elapsed (S407). The large symbol variation time is determined according to the large symbol variation pattern, and the execution of the processing of S408 to S413 is skipped until the variation time elapses (S407: No). On the other hand, if the variation time of the big symbol elapses (S407: Yes), the big symbol determination command set to confirm the stop symbol of the large symbol variation display is set (S408), and then the big symbol symbol is set. It is checked whether or not the odd symbol jackpot is generated in the large symbol variation display executed on the display unit 42a (S409). If the odd symbol jackpot occurs in the large symbol variation display (S409: Yes), the probability variation flag 503c is turned on in order to change the gaming state after the jackpot to the probability variation state (S410), and this processing is terminated. In the process of S409, when the big symbol symbol display that is executed in the big symbol symbol display unit 42a does not generate an odd symbol jackpot, that is, even symbol jackpot variation display or loss variation display. If there is (S409: No), the probability variation flag 503c is turned off in order to change the gaming state after the jackpot to the normal gaming state (S411), and this processing is terminated.

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

  When it is determined that the game is a jackpot (S501: Yes), first, a table corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table (a jackpot symbol is not shown). The table is obtained based on the value of the counter C2 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 you have a predetermined specific symbol (probability variation symbol), you will move to the probability variation state, but if you have a predetermined symbol (non-probability variation symbol) Does not shift to the probability fluctuation 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 checked, and the reach type such as normal reach, super reach, premium reach, etc., and other roughly based on the value of the first variation type counter CS1 And the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) More detailed design variation modes are determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set 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 in the stop symbol command ( S506). In addition, a fluctuation pattern for front / rear out of reach display is determined, and the fluctuation pattern is set as a fluctuation pattern command (S507). At this time, similarly to the processing of S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. The reach type (such as the middle symbol in the present embodiment) is stopped after the reach has occurred based on the value of the second variation type counter CS2 In other words, a more detailed symbol variation mode such as the number of variation symbols) is determined.

  When a reach other than front / rear out is generated (S505: No), the left, middle, and right outreach counters CL, CM, 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 the 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 out symbol counters CL, CM, and CR stored in the complete out symbol buffer of the RAM 503 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, at the time of reach occurrence, or at the time of no reach occurrence, this processing is terminated.

  Next, the accessory symbol control process (S207) will be described with reference to the flowcharts of FIGS. In the accessory symbol control process, first, it is determined whether or not a small hit is currently being made (S521). The small hitting includes the middle of the small hit game displayed on the accessory symbol display unit 42b at the time of the small hit and the middle of a predetermined time after the end of the small hit game. As a result of the determination, if it is a small hit (S521: Yes), this processing is terminated as it is.

  If the small symbol is not being hit (S521: No), it is determined whether or not the small symbol display by the small symbol display unit 42b is being displayed (S522). Then, it is determined whether or not the number of the operation suspension balls M of the small symbol variation display is larger than 0 (S523). If the number M of operation suspension balls is 0 (S523: No), this processing is ended as it is. If the number of operation hold balls M> 0 (S523: Yes), the operation hold ball number M is decremented by 1 (S524), and the data stored in the accessory symbol random number counter buffer is shifted (S525). This data shift process is a process of sequentially shifting the data stored in the accessory holding first to fourth areas of the accessory design random number counter buffer to the accessory executing area side, the accessory holding first area → the accessory executing area, The data in each area is shifted in such a manner that the accessory holding second area → the accessory holding first area, the accessory holding third area → the accessory holding second area, the accessory holding fourth area → the accessory holding third area. After the data shift process, the accessory symbol variation start process is executed (S526). The variation start process will be described later.

  In the process of S522, when the variation display of the accessory symbol is being displayed (S522: Yes), it is determined whether or not the variation time has elapsed (S527). The variation time of the accessory symbol is determined in accordance with the gaming state, and until the variation time has elapsed, the execution of the processing of S528 to S533 is skipped (S527: No), and this processing is terminated. On the other hand, if the change time of the accessory symbol elapses (S527: Yes), the accessory determination command set to determine the stop symbol of the accessory symbol change display is set (S528), and the accessory accessory to be stopped is stopped. It is confirmed whether or not a small hit occurs in the fluctuation display (S529). As a result of the confirmation, when a small hit is not generated in the small symbol variation display to be stopped (S529: No), the present process is terminated, whereas when a small hit is generated in the small symbol variation display to be stopped (S529). : Yes), the process proceeds to S530.

  In the process of S530, it is confirmed whether or not the probability variation flag 503b is turned on, that is, whether or not a small hit occurs in the probability variation state (S530). As a result of the confirmation, if a small hit occurs in the probability variation state (S530: Yes), next, whether or not the number N of active suspended balls (the value of the retained ball counter 503c) of the large symbol symbol is> 2. (S531). If the number N of active reserve balls (the value of the reserve ball counter 503c) of the large symbol variation display is not a value larger than 2 (S531: No), it means that the variation display of the large symbol symbol on standby is less than three. The tulip drive solenoid 33c is energized (turned on) for 4.5 seconds in response to the occurrence of a small hit (S532), and this process is terminated. Note that even when a small bonus hit occurs, the number of suspended action balls for displaying a variation of a large symbol when the probability variation flag 503b is not turned on (S530: No), or even when the probability variation flag 503b is turned on. When N (the value of the holding ball counter 503c) is a value greater than 2 (S530: Yes, S531: Yes), three variations of the large symbol that are waiting in the normal variation state or in the probability variation state are displayed. As described above, the tulip drive solenoid 33c is excited (turned on) for 0.5 seconds in response to the occurrence of a small hit (S533), and this process is terminated.

  By configuring as described above, the tulip 33b can be opened for a long time so that a ball can easily win a big game mouth 33 in a situation where the number of standby times of display of a large symbol symbol is small during the probability variation state, so that the probability variation In the game in the state, the large symbol display unit 42a can avoid the non-execution state of the large symbol variation display as much as possible, and can stably execute the large symbol variation display. Therefore, it is possible to solve the problem that the player who recognizes that the ball is more likely to win the big game mouth 33 in the probability variation state than the normal game state is caused to feel dissatisfaction with the game.

  Next, the accessory variation start process (S526) will be described with reference to the flowchart of FIG. In the accessory change start process (S526), first, it is determined whether or not a small hit is made based on the value of the small hit random number counter C4 stored in the accessory execution area of the small symbol random number counter buffer (S541). When it is determined that the game is a small hit (S541: Yes), the small hit symbol is set to the accessory stop symbol command (S542), and the process proceeds to S544. On the other hand, if it is not a small hit (S541: No), the small hit symbol is set to the accessory stop symbol command (S543), and the process proceeds to S544.

  In the process of S544, it is confirmed whether or not the probability variation flag 503b is turned on (S544). If the probability variation flag 503b is turned on (S544: Yes), a shortened variation pattern whose variation time is 5 seconds is set in the accessory variation pattern command (S545), and this accessory variation start process (S526) is terminated. . On the other hand, in the processing of S544, when the probability variation flag 503b is not turned on, that is, in the normal gaming state (S544: No), the normal variation pattern whose variation time is 30 seconds is set as the accessory variation pattern command. (S546), the accessory variation start process (S526) is terminated.

  Next, payout control executed by the MPU 511 in the payout control device 311 will be described with reference to FIG. FIG. 37 is a flowchart showing the main process of the payout control device 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 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), interrupt is permitted (S918), and the process proceeds to a payout control process to be 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). The MPU 511 peripheral device is initialized (S911), and the used register is 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 a 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). The launch permission is set for the launch control device 312 (S1002), and when the state return switch 321 is checked, if it is determined that the state return operation is started, the state return operation is executed (S1003).

  Thereafter, the setting of the lower pan full tank state or the lower pan full tank release state is executed according to the change in the state of the lower pan 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. Also, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change of the tank ball state (S1005). That is, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when the tank ball is not used, the tank ball no state setting is executed. Perform configuration. Thereafter, the presence / absence of a notification state is determined, and when 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. 39 is started (S1009). . On the other hand, if the prize ball cannot be paid out (S1007: Yes) or if the total number of prize balls is 0 (S1008: Yes), the process proceeds to the lending and payout process. The prize ball control process will be described later.

  In the rental ball payout process of S1010 to S1012, if the rental ball payout is not possible and a rental ball payout request is received from the card unit (S1010: No, S1011: Yes), the rental ball 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 disabled state is not set 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. 39 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 the 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. 40 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 the retry process and the payout motor 358a is stopped (S1205). Thereafter, the payout control process of FIG. Return.

  Further, if the game ball count is normal (S1204: Yes), it is determined whether or not the game ball count by the payout count switch has reached a predetermined number (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. 38 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, in the pachinko machine 10 according to the present embodiment, the opening time of the tulip 33b is determined according to the determination result of the probability variation state or the normal gaming state and the determination result of the number of waiting times for the large symbol variation display. Alternatively, the number of times of opening is changed. Specifically, the tulip 33b is opened for approximately 4.5 seconds in a situation where the change display of the large symbol is waited less than three times during the probability change state. On the other hand, the tulip 33b is released for approximately 0.5 seconds in a situation other than the above situation, that is, in a situation where a large symbol variation display is waited three times or more during the normal gaming state and the probability variation state. By configuring in this way, the tulip 33b can be opened for a long time so that a ball can easily win a big game mouth 33 in a situation where the number of waiting times for display of a large symbol symbol during a probability variation state is small. In the middle game, the large symbol display unit 42a can avoid the non-execution state of the large symbol variation display as much as possible, and can stably execute the large symbol variation display. Therefore, it is possible to solve the problem that the player who recognizes that the ball is more likely to win the big game mouth 33 in the probability variation state than the normal game state is caused to feel dissatisfaction with the game.

  Further, in the pachinko machine 10 according to the present embodiment, the opening mode of the tulip 33b is changed as necessary, that is, in the probability variation state in which the variation display is digested earlier than the normal state, and the number of variation displays on standby is It is configured to be released longer than the normal gaming state only in the situation of less than 3. Therefore, only when there is a situation in which the display of variation of the large-sized symbol on standby is likely to be eliminated and the variation display is not performed on the large-sized symbol display device 42, the opening time of the tulip 33b is set longer than that in the normal gaming state. When the necessity for winning is high, it is possible to easily generate a start winning. Therefore, since it is possible to easily execute the large symbol variation display without changing the prize ball ratio of the pachinko machine 10, it is possible to more easily execute the large symbol variation display to realize the above effect. The problem of causing the player to feel dissatisfied with the game can be solved without causing any disadvantage to the hall (game hall) side where the pachinko machine 10 is installed.

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

  For example, in the pachinko machine 10 of the present embodiment, the accessory symbol variation time is determined only by the gaming state. Instead of this, the variation time of the accessory symbol may be changed in accordance with the number M of suspended operation balls of the accessory symbol variation display. Specifically, when the number P of active suspension balls of the small symbol variation display is a predetermined number (for example, “3”) or more, the “shortened variation pattern” is set even in the normal gaming state. You may do it.

  Further, in the pachinko machine 10 according to the present embodiment, when the probability display is in the state of fluctuation and the number of display changes of the waiting large figure is less than 3, along with the small hit in the change display of the small figure, The opening time of the tulip 33b is configured to be longer than the opening time during the normal gaming state. Instead of this, regardless of the gaming state, that is, whether in the probability variation state or in the normal gaming state, the variation display number of the large symbols on standby is less than a predetermined number (for example, 2) In such a case, when a small hit is generated in the small symbol pattern change display, the opening time of the tulip 33b may be lengthened.
