Description

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

  In recent years, ball-type game machines represented by pachinko machines and the like have become mainstream using display devices such as liquid crystal displays in order to improve the fun of games. In this display device, a game with variable display is generally performed. In the variable display, for example, three symbols are displayed horizontally or vertically in the effective display area, or nine symbols or the like in a 3 × 3 cell, and the displayed symbols are scrolled based on the establishment of a predetermined start condition. Is displayed. As a starting condition, it is supposed that a game ball enters (wins) in a specific winning opening (starting opening) formed in a game area into which a game ball is usually placed. When the symbols, etc., as a variable display are started to be scrolled based on the winning at the starting port and then stopped (at a predetermined stop position), the winning combination is given when the symbols are in a predetermined combination. Become. When the jackpot is won, the variable winning device is opened and the game ball can be won, and the player acquires a large amount of game balls and the like according to the number of winning games as the game value.

  Here, since the gameability preferred by the player is diverse, the gaming machine manufacturer has a plurality of different prize balls and jackpot probabilities even for the same type of game machine so as to match the gameability preferred by the player. A variety of game machines are being developed. For example, there are players who like a game with a high shooting ability capable of acquiring a large amount of game balls in a short time, and a player who likes a game with a low shooting ability with little increase or decrease in the number of game balls even in a long-time game. Therefore, a difference is made in the number of prize balls to be paid out in response to the entry into the winning opening, or a difference is made in the jackpot probability. For amusement halls, it is desirable to install a large number of gaming machines with high shooting characteristics that tend to increase sales, and this kind of gaming machine is also preferred by players who prefer gaming characteristics with high shooting characteristics. On the other hand, a gaming machine with high shooting ability tends to increase the investment burden of the player, and is easily avoided from a player who intends to play a game for a long time with a small investment. In other words, the ratio of a gaming machine having a high shooting ability and a gaming machine having a low shooting ability is one of the factors that directly leads to the ability to attract customers in the game hall. For this reason, game machine manufacturers have developed multiple types of game machines with different gaze characteristics, even if they are the same model, so that they can select models that meet the needs of the players at the game hall. Are working together to improve the ability to attract customers.

  In addition, in order to diversify the game, a variable winning device is provided in the vicinity of the starting port, and the variable winning device is provided on condition that the game ball passes through a passing port provided at a position different from the starting port. Some can be operated to form a state in which a game ball can easily enter the starting port. Specifically, a lottery is performed to determine whether or not to operate the variable winning device at the timing when the game ball passes through the passage opening, and the above-described variation display (hereinafter referred to as variation of the first symbol) based on the passage of the game ball. A variation display (hereinafter abbreviated as a second symbol variation display) is started. The display result is displayed corresponding to the lottery based on the passing of the game ball, and in the case of winning, the second symbol corresponding to the win is displayed to let the player recognize the winning and operate the variable winning device. A state where the game ball easily enters the start port is formed. By controlling this variable prize-winning device to operate at a high rate for a long period of time during a certain period of time, the time required for winning a large amount of game balls at the prize opening is reduced while suppressing the consumption of game balls (hereinafter referred to as “time reduction”). (Abbreviated.) In recent years, gaming machines with games are also being developed.

  In the gaming machine in which the short game is set at this time, the period during which the variable display for a predetermined number of times is executed after that is the time of the short-time game. At this time, during the short game, as compared with the normal game, the operating time of the variable prize winning device based on the passing of the game ball to one passing port is extended, the number of times of operation is increased, Shorten the fluctuation time of the fluctuation display of the lottery, increase the lottery that the variable prize winning device is released, or increase the winning probability of the lottery based on the passing of the game ball to the passage opening, to the start opening Game balls are easy to enter. In addition, during the short-time game, the player can be given a chance to win a large number of jackpot games in a short time by shortening the variation time of the first symbol variation display and promptly displaying the variation display related to the jackpot. There are also things. Thereby, the interval until the next jackpot game is shortened, and a game property that can increase the number of game balls in a short period of time (that is, a high shooting ability) is realized.

In addition, as one means for providing high and low shooting characteristics, there is also a gaming machine in which the number of game balls to be paid out (that is, prize balls) when a game ball is won at a winning opening that triggers the occurrence of a big hit game is set. Has been developed. In such a gaming machine, the winning probability of the jackpot lottery can be increased because the amount of payout of the winning ball based on the winning at the start opening is small, so that the winning speed of the gaming ball is high, and the jackpot game is likely to occur. It can be a gaming machine.
JP 2004-41547 A

  However, in a gaming machine with a short-time game set, if the number of prize balls for winning at the start opening is set to be small, the number of prize balls for winning at the starting opening is small, so it is set to prevent the game balls from being reduced as much as possible. When it is played, the game balls will decrease at a fast pace during the short game. For this reason, there is a problem that it is difficult to set a short-time game while increasing the winning probability of the jackpot lottery.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that can suppress a decrease in game balls in a short time while reducing the probability of jackpot.

  In order to achieve this object, the gaming machine according to claim 1 is formed so as to be visible to a player and a game area where a game ball flows down and a game is played, and a first start provided in the game area An area, first detection means for detecting a game ball entering the first start area, and a lottery when the first detection means detects a game ball entering the first start area. The first identification information is dynamically displayed based on the first lottery means to be performed and the game ball detected by the first detection means, and the lottery result of the first lottery means is displayed after the dynamic display. A first display device for displaying a corresponding display result, a first display control means for controlling display contents of the first display device based on a lottery result of the first lottery means, and a predetermined display by the first lottery means. From the first state to the player on the condition that the lottery result is derived And a variable winning means for generating a special gaming state advantageous to the player by switching to an advantageous second state, and when the predetermined lottery result is derived, a predetermined display result is displayed in the dynamic display. And a predetermined game value is given to the player by the variable winning means, and a first pitching portion forming one of the first starting areas is different from the first pitching portion. A second pitching portion that is provided at a position to form one of the first starting areas and from which a large number of game balls are paid out from the first pitching portion based on the pitch of the game balls; An entry restriction means for restricting the entry of a game ball into the second entry part, and a derivation means capable of deriving the game ball to the second entry part while avoiding the restriction by the entry restriction means; A first derivation state in which it is difficult for a game ball to enter the second entry part, and a first derivation state thereof. The game balls to the second ball entrance portion and a derivation switching means for switching said deriving means and a second resolution status easily ball entrance.

  According to the gaming machine of the first aspect, the second pitching portion that makes it easy for a game ball to enter by the derivation means switched by the derivation switching means is a first in which a large number of game balls are paid out from the first pitching portion. This is the starting area. Therefore, the first derivation state (normal game state) in which little or no game balls enter the second entry part by the entry restriction unit, and the restriction by the entry restriction unit by the derivation unit are avoided. It can be formed by switching from a derived state (normal game state) to a second derived state (for example, a short-time game state) in which a large amount of game balls are likely to enter the second entry part. Therefore, in the first derivation state (normal game state), the game balls are hardly entered only in the first entry part where the number of payout of game balls based on the entry is small. On the other hand, the winning probability of the special gaming state can be increased without reducing the total number of game balls that can be acquired by the player. On the other hand, in the second derivation state (short-time gaming state), it is difficult for the number of game balls to decrease by entering a large number of game balls into the second ball-in part where the number of payouts based on the game balls entering is large. A gaming state can be realized. Therefore, the number of game balls to be paid out when entering the first starting area can be greatly varied by the operation of the derivation switching means, and the number of game balls to be paid out during the first derivation state (normal game state) is suppressed. Thus, there is an effect that it is possible to suppress a decrease in game balls in the second derived state (short-time game) while increasing the probability of occurrence of the special game state.

  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. FIG. 3 is a front view of the game board 16 of the pachinko machine 10.

The launch solenoid 92 is for firing a game ball with a strength corresponding to the resistance value of the variable resistor that changes in accordance with the amount of rotation of the operation handle 310, and thereby the amount of flight corresponding to the player's operation. A game ball is driven into the front of the game board 16.

  As shown in FIG. 3, the game board 16 includes a wooden base plate 60 cut into a substantially square shape when viewed from the front, a large number of nails and rails 61 and 62 for guiding a game ball, a general winning opening 63, and a liquid crystal display. The first symbol display device 81 and the like configured by a display (hereinafter simply referred to as “LCD”) are assembled. An outer rail 62 formed by bending a strip-shaped metal plate into a substantially arc shape is planted on the front surface of the game board 16, and the strip-shaped metal plate is located on the inner side of the outer rail 62 in the same manner as the outer rail 62. The arc-shaped inner rail 61 formed by the above is planted. The inner rail 61 and the outer rail 62 surround the outer periphery of the front surface of the game board 16, and the game board 16 and the glass unit 17 (the plate glass 151) surround the front and rear. A game area where a game is played is formed according to the behavior.

  The game area is provided with a plurality of general winning ports 63 through which 5 to 15 balls are paid out as prize balls when a game ball wins. Further, a variable display device unit 80 having a first symbol display device 81 is disposed in the central portion of the game area, and the variable display device unit 80 is controlled by a display control device 505 described later, so that a plurality of types can be obtained. A variation display in which the symbols as the identification information vary according to a predetermined order is displayed on the display screen of the first symbol display device 81. Instead of the LCD, for example, the first symbol display device 81 may be configured using a reel or the like.

  A start winning unit 64 is disposed below the variable display unit 80. The start winning unit 64 is formed by combining a plurality of members made of synthetic resin. The start winning unit 331 is an upper start winning port 331 that serves as a first entering portion into which a game ball can enter and a second entering portion. A lower start winning opening 332 is formed. The upper and lower start winning openings 331 and 332 constitute a first start area as an opportunity for the big hit lottery, and are provided on the back side of the game board 16 when a game ball enters one of the start winning openings. The upper start port switch 524a or the lower start port switch 524b (see FIG. 24) is turned on, and the first symbol display device 81 described above starts the variable display of symbols. In addition, when a game ball enters the upper start winning opening 331, one game ball is paid out as a prize ball, and in the lower start winning opening 332, five game balls are paid out as a prize ball.

  A variable winning device 65 is disposed below the start winning unit 64, and a horizontally-long rectangular specific winning opening (large winning opening) 65a is provided at a substantially central portion thereof. In the pachinko machine 10, a lottery is performed in response to a game ball entering the first entrance, and when the lottery is won, the first symbol display device 81 displays a lottery in advance after the symbol changes. One of the determined symbol combinations is displayed to indicate to the player that the jackpot has been generated, and then the gaming state transitions to a special gaming state in which the game ball is easy to win. As this special gaming state, the large winning opening 65a that is normally closed is opened for a predetermined time (for example, until 30 seconds elapses or 10 game balls are won).

  In the big prize opening 65a, a normal area and a V zone as a specific area are separately provided. If the game ball passes through the V zone while the big prize opening 65a is opened, the right to continue is given. After the establishment and closing of the special winning opening 65a, the special winning opening 65a is opened again for a predetermined time. The opening / closing operation of the special prize opening 65a can be repeated up to 16 times (16 rounds), for example. The state in which this opening / closing operation is performed is one form of a special gaming state advantageous to the player, and the player is given out a larger amount of prize balls than usual to give gaming value (game value). Is done.

  The special gaming state is not limited to the above-described form. A large opening opening that is opened and closed separately from the large winning opening 65a is provided in the game area, and when the display result after variation of the first symbol display device 81 matches one of the predetermined symbol combinations, 65a is opened for a predetermined time, and a large opening that is provided separately from the big winning opening 65a when the game ball wins into the big winning opening 65a is opened for a predetermined time. A gaming state that is released a number of times may be formed as a special gaming state.

  Next, the configuration of the pachinko machine 10 will be roughly divided into an outer frame 12, an inner frame 13, a game board 16, a front frame 14, a lower tray unit 15, and a glass unit 17. Will be described. First, the configuration of the outer frame 12 will be described with reference mainly to FIGS. 2 and 6. Here, FIG. 6A is a perspective view of the outer frame 12, and FIG.

  As shown in FIG. 2, the pachinko machine 10 is provided with an outer frame 12 that forms an outer shell thereof, and an inner frame 13 is supported by the outer frame 20 so as to be opened and closed. In the game hall, the outer peripheral surface of the outer frame 20 is fixed to an installation location called an island of the game hall. Since the inner frame 13, the front frame 14, and the lower dish unit 15 are configured to be openable to the front side with respect to the outer frame 12, Inspection and adjustment are performed with the inner frame 13 and the like opened to the front side with respect to the outer frame 12.

  The outer frame 12 is made of a wooden plate material that forms four sides on the top, bottom, left, and right to form a rectangular wooden frame 20 as a whole, and hinges 21 and 22 and receiving brackets 23 and 23 are attached to the wooden frame 20. is there. The joint portion of the wooden frame 20 is fixed by a detachable fastener such as a small screw, and a part of the wooden frame 20 can be easily reused as compared with a structure that is fixed using a nail or a rivet. Yes. In the present embodiment, the outer dimension of the outer frame 12 is 809 mm (inner dimension of about 710 mm), and the outer dimension of the left and right direction is 518 mm (inner dimension of about 480 mm). The outer frame 12 may be made of a light metal such as aluminum or a resin.

  As shown in FIG. 6A, metal upper hinges 21 and lower hinges 22 are attached to the outer frame 12 at two upper and lower portions on the left side when viewed from the front to support the inner frame 13. The inner frame 13 is supported to be openable and closable by using the side on which the hinges 21 and 22 are provided as an opening / closing axis.

  The metal fittings 23 of the outer frame 12 are screwed into the upper and lower two places on one side of the inner side of the wooden frame 20 and away from the hinges 21 and 22 with screws. Each receiving bracket 23 is formed by bending a metal plate, and as shown in FIG. 6B, a mounting portion 23a that is in close contact with the inner surface of the outer frame 12, and the inner surface side of the outer frame 12 from the mounting portion 23a. An engaging portion 23b that rises vertically toward the front, and a protruding portion 23c that protrudes toward the closing direction side of the inner frame 13 (the upper left side in FIG. 6B) at the distal end side of the engaging portion 23b. And has. The front end portion of the inner frame collar member 411 (see FIG. 25) formed to project from the inner frame 13 in a hook shape is caught on the engaging portion 23 b of the receiving metal 23, and the inner frame 13 is closed.

  The protrusion 23c of the metal fitting 23 has an inner frame flange toward the inner surface side of the outer frame 12 (the lower left side in FIG. 6B) with the inner frame 13 closed with respect to the outer frame 12. It is formed so as to protrude beyond the length that overlaps the tip portion protruding downward of the member 411. For this reason, the movement of the distal end portion of the inner frame collar member 411 toward the inner surface side of the outer frame 12 is restricted by the protruding portion 23c, and the protruding amount of the metal fitting 23 toward the inner surface side of the outer frame 12 is reduced. It is prevented that the inner frame collar member 411 is accidentally detached from the receiving metal fitting 23 due to the shakiness of 13 and the inner frame 13 is inadvertently opened.

  On the lower side of the outer frame 12, a decorative plate 24 formed of a horizontally long rectangular synthetic resin, specifically, an ABS resin plate, is fixed from the back side of the outer frame 12 by screws passing through the wooden frame 20. Yes. Due to the decorative plate 24, most of the outer frame 12 exposed on the front side of the pachinko machine 10 is made of synthetic resin like the inner frame 13, the front frame 14 and the lower dish unit 15, and a sense of unity is provided between the members. Born to improve appearance quality. Although omitted in the present embodiment, different external shapes can be used while sharing the wooden frame 20 which is the wooden portion of the outer frame 12 by applying a pattern following the shape of the lower dish unit 15 on the front surface of the decorative plate 24. Can be manufactured, and the appearance quality of the pachinko machine 10 can be improved while effectively reusing the wooden frame 20.

  On the upper surface of the decorative plate 24, metal sliding plates 25 and 26 are provided at two locations, that is, an end portion on the side away from the hinge 22 and a central portion. Even if the opened inner frame 13 falls downward with respect to the outer frame 12 due to its own weight, when the inner frame 13 is closed, its lower surface is lifted while being rubbed against the sliding plates 25 and 26, and the inner frame 13 Guided to a fixed position. For this reason, it is not necessary for the operator to perform the closing operation while lifting the inner frame 13, and the convenience of the opening / closing operation of the inner frame 13 is enhanced. In addition, compared to the case where a part that guides the inner frame 13 to a fixed position is formed by a resin or wooden part, parts are prevented from being scraped or damaged due to rubbing due to repeated opening and closing operations. The opening / closing operation of the inner frame 13 can be easily performed over a long period of time.

  One of the two sliding plates 25, 26 is provided at an end portion on the side away from the hinges 21, 22 serving as the opening / closing shaft of the inner frame 13. For this reason, both lower side ends of the inner frame 13 are supported by the metal lower hinge 22 and the sliding plate 26, and the inner frame 13 is guided to a fixed position in a more stable state. Further, the other sliding plate 25 is provided at a substantially intermediate position between the hinge 22 and the sliding plate 26, and the most easily depressed portion is guided by the support of the hinge 22 and the sliding plate 26 provided at the end. It becomes. Thus, by providing the two sliding plates 25 and 26 at the end portion and the center portion on the side away from the hinge 22 on the upper surface of the decorative plate 24, the inner frame 13 can be reliably guided at a fixed position, Even if the weight applied to the inner frame 13 increases due to a large amount of game balls entering the upper plate 201 or the lower plate 301, the opening / closing operation of the inner frame can be easily performed.

  On the back side of the upper surface of the decorative plate 24, a rib 27 is provided so as to protrude upward to a position overlapping the lower end of the inner frame 13 along the front-rear direction of the pachinko machine 10. Further, a groove 27 a that is recessed toward the back surface along the upper surface of the decorative plate 24 is formed at the base portion of the rib 27, and the upper end portion of the rib 27 is formed so as to protrude toward the front surface side of the pachinko machine 10. For pachinko machines, fraudulent acts that are performed by inserting a thin plate-like tool or the like through the gap between the members are frequently reported, but in the pachinko machine 10 of the present embodiment, the tool is started from the lower side of the inner frame 13. Since the rib 27 prevents the action of inserting etc., fraudulent acts can be prevented. Further, the tool inserted from between the inner frame 13 and the decorative plate 24 is likely to be fitted into the groove 27a provided at the base portion of the rib 27, which makes it more difficult to cheat.

  The height of the ribs 27 on the upper surface of the decorative plate 24 is set lower than the radius of the game ball with respect to the upper surface of the decorative plate 24. For this reason, even if a game ball is on the top surface of the decorative plate 24 when the inner frame 13 is closed, the game ball gets over the rib 27 after being sandwiched between the lower end portion of the inner frame 13 and the rib 27. Accordingly, the provision of the rib 27 prevents illegal actions, and the game ball is not sandwiched between the rib 27 and the inner frame 13 so that the trouble of reclosing the inner frame 13 does not occur. Convenience for the opening / closing operation can be kept high.

  Next, the inner frame 13 will be described mainly with reference to FIGS. 2 and 7. FIG. 7 is a front view of the pachinko machine 10 with the front frame 14 and the lower dish set 15 removed. Further, in FIG. 7, for convenience, a part of the configuration in the game area on the surface of the game board 16 is shown blank.

  The inner frame 13 is mainly composed of an ABS resin-made inner frame base 30 formed in a rectangular shape, and a substantially circular central window 30 a is formed at the center of the inner frame base 30. An attachment portion for the game board 16 is provided on the back side of the inner frame base 30, and the game board 16 is detachably attached.

  The inner frame 13 is a door-like member that is rotatably supported with respect to the outer frame 12 by the upper hinge 21 and the lower hinge 22 of the outer frame 12 described above. The opening / closing axis of the inner frame 13 extends vertically on the left side of the front view of the pachinko machine 10 provided with the hinges 21, 22, and the inner frame 13 is opened forward with the opening / closing axis serving as an axis. The opening / closing axis of the inner frame 13 is set on the side opposite to the operation handle 310 (see FIG. 1) provided on the right side when viewed from the front of the pachinko machine 10 (left side when viewed from the front). ing. Usually, in the pachinko hall, the pachinko machines 10 are arranged adjacent to each other. Therefore, when the opening / closing axis is provided on the operation handle 310 side, the operation handle 310 that moves along with the opening of the inner frame 13 moves to the adjacent pachinko machine 10 or the pachinko machine. This is because the amount of opening is limited by contacting a card unit or the like provided between the machines 10.

  An outer peripheral wall 30b is formed on the outer periphery of the inner frame 13 so as to project to the front side, and the front frame 14 and the lower dish unit 15 are disposed inside the outer peripheral wall 30b. That is, in a state where the front frame 14 and the lower dish unit 15 are attached to the inner frame 13, the outer periphery of each side surface of the front frame 14 and the lower dish unit 15 is surrounded by the outer peripheral wall 30 b of the inner frame 13. For this reason, it becomes difficult to insert a wire or a thin plate-like tool between the front frame 14 or the lower tray unit 15 and the inner frame 13, and it is possible to suppress fraud.

  As shown in FIG. 2, a wiring port 30 c is provided through the inner frame base 30 in the upper left portion of the inner frame 13. In the wiring port 30 c, wiring of components used for electrical decoration or the like of the front frame 14 is inserted into the back side of the inner frame 13 and connected to the back side of the game board 16. Rs are formed at the corners of the wiring port 30c, and even if each cord wired in the wiring port 30c is rubbed by the wiring port 30c by opening and closing the front frame 14, it is difficult to be damaged. The game board 16 (base plate 60) is also provided with a wiring port 60a at a position (upper left) corresponding to the wiring port 30c of the inner frame 13, and the gaming board 16 is attached to the inner frame base 30. Wiring is possible.

  Next, a configuration of the game board 16 and the vicinity of the variable display unit 80 provided on the game board 16 will be described with reference mainly to FIG. FIG. 3 is a front view of the game board 16.

  The game board 16 is configured by assembling a base plate 60 formed of a quadrangular plywood with a nail, a windmill, a winning opening 63, and the like, and the inner frame 13 with its peripheral edge abutting against the back side of the inner frame base 30. It is attached to the back side. The front center portion of the game board 16 is exposed to the front side of the inner frame 13 through the central window 30 a of the inner frame base 30. The vertical length of the game board 16 is about 480 mm, and the length in the left-right direction is about 450 mm, which is the same size as the conventional one.

  The game board 16 includes the above-described general prize opening 63, start prize unit 64, variable prize device 65, variable display device unit 80, and the like disposed in through holes formed in the base plate 60 by router processing. It is fixed with a wood screw etc. from the front side. In addition to the above-described winning opening, the game board 16 is provided with an out opening 66 and a second entrance (through gate) 67. A game ball that has not entered any of the winning openings 63, 65a, 331, 332 is guided to a ball discharge path (not shown) through the out opening 66. A number of nails are planted on the game board 16 in order to disperse and adjust the falling direction of the game ball as appropriate, and various members (servants) such as a windmill are arranged.

  The variable display unit 80 includes a light emitting diode (hereinafter abbreviated as “LED”) that displays the second symbol (ordinary symbol) in a variable manner with the passage of the game ball at the second entrance 67 as a trigger. There are provided a two symbol display device 82 and a first symbol display device 81 for variably displaying the first symbol (special symbol) triggered by a winning (winning) at each start winning opening 331, 332. The second symbol display device 82 includes a second symbol display unit 83 and a holding lamp 84, and each time a game ball passes through the second entrance 67, the display unit 83 displays a display symbol (second symbol). As the symbol “○” and “×” symbol are alternately lit, the variable display is performed, and when the variable display stops at a predetermined symbol (in this embodiment, “○” symbol) The blade 333 that guides the game ball to the two-stage member 3622 is configured to be in an activated state (see FIG. 5) that is opened (opened) for a predetermined time. The number of times that the game ball passes through the second entrance 67 is held up to a maximum of 4 times, and the number of times the game ball is passed is displayed on the hold lamp 84. Note that the second symbol variation display is performed by switching on / off of a plurality of lamps in the display unit 83 as in the present embodiment, and a part of the first symbol display device 81 is used. May be performed. Similarly, the hold lamp 84 may be turned on by a part of the first symbol display device 81.

  Further, when a game ball enters one of the start winning ports 331 and 332 while the first symbol display device 81 is performing the variable display of the first symbol, the number of times that the ball is entered is a maximum of four times. The number of times of the hold is displayed by the number of lights of the hold lamp 85. The four holding lamps 85 are provided for the maximum number of holdings, and are arranged symmetrically above the first symbol display device 81. In the present embodiment, the winning winning holes 331 and 332 and the passing of the second winning hole 67 are configured to be held up to 4 times each, but the maximum holding number is 4 times. It is not limited and may be set to 3 times or less, or 5 times or more (for example, 8 times). Further, the hold lamp 85 is deleted, and the number of times of variable display hold based on the winnings to the start winning ports 331 and 332 is displayed as a part of the first symbol display device 81 or as an area divided into four. You may make it display in a different mode (for example, a color and a lighting pattern) by the number of times of holding.

  4 and 5, the detailed configuration of the variable display device unit 80 provided in the game board 16, the configuration of the start winning unit 64 also provided in the game board 16, and the start winning unit 16 The arrangement of the peripheral nails will be described. FIG. 4 is a perspective view showing the closed state in which the blade 333 provided at the upper part of the variable display unit 80 is closed together with the start winning unit 64 and the peripheral nails. FIG. It is the perspective view which showed the open state with which the blade | wing 333 was open | released. The variable display device unit 80 includes a first stage member 361 capable of rolling a game ball at a position below the first symbol display device 81, and a concave portion formed in the central portion of the first stage member 361. A first derivation unit 361a capable of deriving a game ball to the winning opening 331; a second stage member 362 provided between the first stage member 361 and the first symbol display device 81 and capable of rolling the game ball; A second lead-out portion 362a formed in a concave shape in the center portion of the two-stage member 362, a warp hole 362b provided in the second lead-out portion 362a portion, and a second lead-out provided in the variable display device unit 80. A warp route 362c capable of deriving a game ball from the portion 362a to the lower start winning opening through the warp hole 362b, and the game ball flowing into the warp route 362c into the lower start winning opening 3 2, a discharge hole 362 d that discharges to the upper part in the vertical direction, a first lead-out passage 80 a that can lead the game ball to the first stage member 361, and a second lead-out passage 80 b that can lead the game ball to the second stage member 362. Is provided. In addition, a starting port opening solenoid (not shown) for operating the blade 333 is disposed on the back side of the game board 16 with respect to the base member 343. There are provided passages for discharging and start port switches 524a and 524b (see FIG. 24) for detecting game balls that have entered the respective start winning ports 331 and 332. The upper start winning opening 331 and the lower start winning opening 332 are arranged vertically, and the player moves his eyes to confirm the winning of the game ball to each start winning opening 331,332. Without or with a little eye movement.

  The blade 333 is made of synthetic resin, and has an axis perpendicular to the surface of the game board 16 as an axis, and is inclined to the left and right sides with the lower side as a fulcrum along the surface of the game board 16 where the game area is formed. It is supported by the variable display unit 80 as possible. The blades 333 normally stand upward and form a closed state in which the second lead-out passage 80b for leading the game ball to the second stage member 362 is closed. Since the lower start winning opening 332 is covered by the side wall 332b, it is difficult to win unless the game ball flows into the warp hole 362b of the second stage member 362. Since it is difficult for the game ball to be led out to the second stage member 362, the game ball is extremely difficult to enter the lower start winning opening 332. When the game ball passes through the second entrance 67, a lottery is performed by the main controller 561 described later based on the timing of the passing, and when the lottery is won, 0.4 seconds or 4 seconds are selected depending on the game state. During any period of time, the start-port opening solenoid in the non-excited state is normally excited, and an open state (the state of FIG. 5) in which the blades 333 are opened is formed. In this open state, the upper surface of the blade 333 is inclined downward toward the second lead-out passage 80b, and the game ball is drawn into the second lead-out passage 80b and led to the second stage member 362. It should be noted that various known techniques can be used for the structure and control in which the “◯” mark is lit on the second symbol display portion 83 and the blade 333 is opened and closed.

  Here, the upper start winning opening 331 is opened upward so that a game ball can always enter, and the lower start winning opening 332 makes it difficult to enter the game ball by the side wall 332b. Only when the open state is formed, the game ball is led out to the second stage member 362 so that the game ball can easily enter the lower start winning opening 332. Therefore, by controlling the operation of the blade 333, it is possible to prevent little or no game ball from entering the lower start winning opening 332 except in a specific gaming state (for example, during short-time gaming). The lower start winning opening 332 is a winning opening from which five game balls corresponding to five times the upper start winning opening 331 are paid out as winning balls. Therefore, the upper start winning opening 332 is used to display the variation of the first symbol. By mainly using the winning opening 331, the number of game balls to be paid out in accordance with the execution of the variable display of the first symbol can be reduced, and the total number of game balls that can be obtained by the player with respect to one jackpot The winning probability of the jackpot lottery (that is, the probability of occurrence of the special gaming state) can be set higher without decreasing. In addition, it is preferable that the upper start winning opening 331 pays out one game ball based on the entry of the game ball, so that the winning probability of the big hit lottery can be set high. It is easy to set the winning opening 332 so that four or more game balls are paid out so that the game balls are not decreased during the short game when the blades 333 are frequently opened and closed.

  Returning to FIG. The display content of the first symbol display device 81 is controlled by a display control device 505 described later, and, for example, three symbol rows of left, middle, and right are displayed. Each symbol row is composed of a plurality of symbols, and these symbols are vertically scrolled for each symbol row so that the first symbol is variably displayed on the display screen of the first symbol display device 81. In the present embodiment, the first symbol display device 81 is constituted by a large liquid crystal display having an 8-inch size, and the variable display device unit 80 includes a center frame 86 so as to surround the outer periphery of the first symbol display device 81. Is arranged.

  The variable winning device 65 opens and closes a large winning opening 65a formed in a horizontally long rectangular shape at the center. Specifically, a horizontally-long rectangular opening / closing plate covering the special winning opening 65a and a special winning opening opening solenoid for driving to open / close forward with the lower side of the opening / closing plate as an axis are provided. The special winning opening 65a is normally closed so that a game ball cannot be won or difficult to win. In the event of a big win, the big winning opening opening solenoid is driven to tilt the opening / closing plate downwards in the front to temporarily form an open state where the game ball is likely to win the big winning opening 65a. It operates so as to alternately repeat the closed state and the closed state.

  The two rails 61 and 62 provided on the game board 16 are provided for guiding the game balls launched from the ball launch unit 90 to the upper part of the game board 16. A game ball launched in accordance with the turning operation of the operation handle 310 is guided to the game area via a path sandwiched between the two rails 61 and 62. Both rails 61 and 62 are made of a stainless steel metal band, and the inner rail 61 is fixed to the base plate 60 in a state of being bent into an annular shape excluding the upper right semicircle. The outer rail 62 is fixed to the base plate 60 such that a part (mainly the left side) faces the inner rail 61. The inner rail 61 and the outer rail 62 mainly constitute a guide rail, and a ball that guides the game ball to the game area by a portion where the rails 61 and 62 are parallel to each other at a predetermined interval (a portion on the left side). A guide passage is formed.

  A return ball preventing member 68 is attached to the tip of the inner rail 61 (upper left portion in FIG. 3). As a result, it is possible to prevent a situation in which the game ball once guided from the ball guide path between the inner rail 61 and the outer rail 62 to the upper portion of the game board 16 returns to the ball guide path again. A resin arc member 70 formed by providing an arc connecting the rails on the inner surface side between the lower right end of the inner rail 61 and the upper right end of the outer rail 62 is a base. The plate 60 is driven and fixed. A return rubber 69 is attached to the front end portion of the outer rail 62 (upper right portion in FIG. 3) at a position corresponding to the maximum flying portion of the game ball. The game ball fired at a predetermined momentum or more hits the return rubber 69 and is bounced back toward the center while the momentum is attenuated.

  In the lower right corner and the lower left corner of the game board 16, there are provided adhering spaces K1, K2 for adhering seals or plates such as stamps. Since the game board 16 itself has sticking spaces K1 and K2 such as stamps, the game board 16 can be uniquely identified by the stamps and the like, and it is easy to find an exchange for an illegal game board 16. Can do.

  Next, the game area will be described. The game area is a substantially circular area that is formed in front of the game board 16 and defined by the two rails 61 and 62 and the arc member 70. In this embodiment, the game area is a guide rail that is a parallel part of the inner rail 61 and the outer rail 62 in the area surrounded by the inner rail 61, the outer rail 62, and the arc member 70 when viewed from the front of the pachinko machine 10. The area is excluded. Therefore, in the case of a game area, the guide rail portion is not included, and the left limit position toward the game area is specified by the inner rail 61 instead of the outer rail 62. Similarly, the right limit position toward the game area is specified by the arc member 62. Further, the lower limit position of the game area is specified by the inner rail 61. The upper limit position of the game area is specified by the outer rail 62.

  In the pachinko machine 10, the distance from the upper end of the game area (the uppermost point of the outer rail 62) to the lower end of the game area (the lowermost point of the inner rail 61) is 445 mm (about 58 mm longer than the conventional product). The distance from the left end (the extreme left position of the inner rail 61) to the right end of the game area (the extreme right position on the inner surface of the arc member 70) is 418 mm (about 50 mm longer than the conventional product). That is, the game area of the pachinko machine 10 is configured to be much larger by being expanded in the left-right direction and the up-down direction than before. Therefore, the windmill, the second entrance 67, a plurality of nails (such as a guide nail for guiding the game ball to the center), and other accessories can be arranged in various ways, and the behavior of the game ball can be varied. You can make the ball game more interesting.

  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 16 is about 70%, which is much larger than the conventional area ratio. Since the area ratio of the game area to the surface of the game board 16 has been only about 50% in the past, it can be said that the game area is considerably expanded on the premise that the game board 16 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 16 must be the same, the surface of the game board 16 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. Further, it may be 80% or more.

  Moreover, 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 second entrances 67 (through gates) located on both sides of the variable display device unit 80 have a guide mechanism for bringing the passed game balls to the center of the game area. This guide mechanism is configured by providing an inclined surface that descends toward the center side of the game area below the second entrance 67. As a result, even if the game area is expanded in the left-right direction by providing a large LCD in the center of the game area in the variable display device unit 80, the game ball can be moved to the start prize unit 64 or the variable prize apparatus at the center of the game area. As a result, it is difficult for the game ball to enter the start winning ports 331 and 332 formed by the start winning unit 64 due to the expansion of the game area, or the path of the game ball is narrowed. It is possible to suppress a decrease in interest due to the monotonous behavior of the game ball.

  Next, the ball launching unit 90, the passage forming member 36, and the relay board 38 which are attached to the lower part on the front side of the inner frame base 30 and constitute a part of the inner frame 13 will be described mainly with reference to FIGS. To do. 8 is a front view of the ball launching unit 90, FIG. 9 is a perspective view thereof, and FIG. 10 is an exploded perspective view thereof. 11 is a perspective view of the ball launching unit 90 in a state in which the opening / closing member 102 constituting the ball feeding mechanism 94 is opened. FIG. 12 is a perspective view of the ball feeding mechanism with the lid member 103 removed from the state of FIG. FIG. 9 is a perspective view of a ball launch unit 90 showing the internal configuration of 94.

  The ball launch unit 90 includes a base plate 91 fixed to the attachment surface 30f below the inner frame base 30 with screws, a launch solenoid 92 attached to the base plate 91, and a longitudinal direction of the launch solenoid 92 on one end side of the launch solenoid 92. A launch rail 93 having a substantially M-shaped cross section that is attached and fixed to the base plate 91 so as to extend parallel to the base plate 91, and guides the game balls one by one to the base end portion (the end portion on the launch solenoid 92 side) of the launch rail 93 A ball feeding mechanism 94 for guiding, and a positioning member 95 (see FIG. 11) attached to the base plate 91 so as to support and position the game ball placed on the base end portion of the firing rail 93 are provided. Yes.

  The base plate 91 is formed by pressing a metal flat plate such as a zinc alloy, and is fixed by screws 96 while being in close contact with the mounting surface 30 f of the inner frame base 30. As shown in FIG. 10, the base plate 91 is provided with a fastening hole for inserting the screw 96, and the boss 91 a and the bolt 91 b for fixing the firing solenoid 92 and the firing rail 93 are secured. The boss 91c is fixed.

  The mounting position of the base plate 91 is desired to be highly accurate so as to be stable with respect to the inner frame base 30 even when many pachinko machines 10 are manufactured. When the relative position with respect to the game board 16 changes for each pachinko machine 10, the jump amount of the game ball fired by the launch solenoid 92 differs accordingly, and the jump amount of the game ball corresponding to the turning operation of the operation handle This is because each pachinko machine 10 becomes unstable. In the pachinko machine 10 of the present embodiment, the base plate 91 is made larger than the conventional one, and the relative mounting position with the inner frame base 30 is stabilized. Specifically, the lower end of the base plate 91 extends below the pivot axis (position indicated by AH in FIG. 7) of the operation handle 310, and the right end thereof is substantially the same as the right end of the game board 16, Its left end extends to the left side from the out port 66 so as to cross the center of the game area, and its upper end extends to a position close to the lower end of the game board 16. Further, the number of screws 96 for fixing the base plate 91 is increased (six) from the conventional one. Further, the fastening position of each screw 96 (see FIG. 7) is separated from the conventional one. For example, the fastening position of the lower screw 96 is below the rotation axis AH of the operation handle 310, and the mounting position is stable. We are trying to make it.

  The firing rail 93 guides the game ball immediately after being fired by the firing solenoid 92, and extends to a boss 91c fixed to the base plate 91 so as to extend linearly while maintaining a predetermined launch angle (launch angle). It is fixed with screws (not shown). A game ball that is launched in accordance with the turning operation of the operation handle 310 is first launched obliquely upward along the launch rail 93, and then through the guide rail formed between the two rails 61 and 62 as described above. Guided to the gaming area.

  Here, in the case of this pachinko machine 10, it has already been described that the game area is greatly expanded as compared with the conventional case, but in such a configuration, the distance between the launch position of the game ball and the game area becomes closer and the launch rail becomes shorter. It tends to be. If the launch rail 93 is short, the ball guiding distance is shortened and the variation of the launch ball is increased. Therefore, a device for stabilizing the launch ball is required. In this embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 93 is somewhat larger than the existing one (that is, the launch rail 93 is raised). The length of the ball is about 240 mm to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the launching device can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 93 is formed so as to extend from the launch position of the game ball hit by the launch solenoid 92 to a position beyond the center position (out port 66) of the game area.

  Further, in the pachinko machine 10, as a launching device for launching a game ball, a single unit solenoid (launching solenoid) in which a linear solenoid is housed in a case member, instead of a combination of a motor and a launching rod that are generally used conventionally. 92 is adopted. The firing solenoid 92 is provided with a metal plunger 92a disposed parallel to the firing rail 93 and a longitudinal direction, and a resin cap 92b covering the tip of the plunger 92a. As the material of the cap 92b, a polyester-based thermoplastic elastomer is employed in the present embodiment. While the player is turning the operation handle 310, the firing solenoid 92 repeats excitation and de-excitation every predetermined time, and the plunger 92a is repeatedly moved up and down accordingly. When the plunger 92 a protrudes, the game ball positioned on the launch rail 93 by the positioning member 95 is launched toward an obliquely upward direction directed by the launch rail 93. A variable resistor linked to the operation handle 310 is connected to the firing solenoid 92, and the protruding speed of the plunger 92a is adjusted based on the operation amount of the operation handle 310 (the stroke amount is substantially constant), and the game ball is fired. The speed and thus the jump amount is adjusted by the amount of rotation of the operation handle 310.

  As shown in FIG. 10, the firing solenoid 92 is fixed to a pair of bosses 91a and bolts 91b erected on the base plate 91 by attaching bolts 97 and nuts 98 thereto. The firing solenoid 92 is provided with a fastening hole 92c through which the bolts 91b and 97 are inserted at positions corresponding to the boss 91a and the bolt 91b. In the ball launching unit 90, the height of the firing solenoid 92 relative to the base plate 91 is made different by adjusting the tightening of the bolts 97 and nuts 98 provided above and below the firing solenoid 92, so that the plunger 92a and the firing rail 93 The relative mounting position can be adjusted, and the hitting point of the game ball can be adjusted. Even when there are variations in manufacturing and assembling of each part during the manufacture of the pachinko machine 10, the ball launch unit 90 is assembled to the pachinko machine 10 and then the bolts 97 and nuts 98 are adjusted to reduce the flying amount of the game ball. Can be adjusted. The firing solenoid 92 is entirely disposed inside the outer peripheral edge of the base plate 9l. When the ball firing unit 90 is assembled to the inner frame base 30 from the base plate 91 side, the firing solenoid 92 is another part. It is prevented from being caught and damaged.

  The positioning member 95 is a member for supporting the game ball placed on the right end portion (base end portion) of the firing rail 93 and positioning the game ball at the hitting position, as shown in FIG. The base plate 91 is formed so as to protrude in a columnar shape on the surface side where the firing rail 93 is provided. The positioning member 95 is provided with a fastening hole penetrating along the axial direction, and the positioning member 95 is screwed to the base plate 91 by inserting a screw into the fastening hole. Here, the fastening hole of the positioning member 95 is formed not at the center of the columnar shape but at an eccentric position. For this reason, it is possible to slightly change the hitting position of the game ball placed on the firing rail 93 by rotating the positioning member 95 appropriately and then tightening the screw, and at the time of manufacturing and manufacturing the pachinko machine 10 Later, it is possible to easily adjust the jump amount of the game ball.

  The ball feeding mechanism 94 feeds the game balls continuously guided from the upper plate 201 to the base end portion of the launch rail 93 one by one. The ball feeding mechanism 94 is made of a resin base member 101 fixed to the base plate 91 so as to cover the upper part of the firing solenoid 92, and is pivotally supported on one side (right side in FIG. 8) of the base member 101 to open and close. And a resin opening / closing member 102 configured to be capable of being used. The base member 101 is integrally formed with a locking claw 101a toward the front side where the opening / closing member 102 is provided. The opening / closing member 102 has a locking claw 101a in a closed state overlapping the front surface of the base member 101. A locking hole 102a is formed to be hooked. Normally, the opening / closing member 102 is in a closed state in which one side is pivotally supported by the pedestal member 101 and the other side is locked to the pedestal member 101 by the locking hole 102a and overlaps and is fixed to the front surface of the pedestal member 101. This closed state is released by removing the locking claw 101 a of the base member 101 from the locking hole 102 a of the opening and closing member 102, and the opening and closing member 102 can be opened forward with respect to the base member 101. Further, the opening / closing member 102 can be slid upward to be detached from the pedestal member 101 by being opened to the maximum with respect to the pedestal member 101.

  The lower part of the pedestal member 101 is formed in a shape inclined downward toward the front side of the lower dish unit 15 while covering the upper gap between the lower dish unit 15 and the mounting surface 30f of the inner frame base 30. Further, on the left side of the pedestal member 101 when viewed from the front, the passage forming member 36 covers the upper gap between the lower plate unit 15 and the mounting surface 30 f of the inner frame base 30 on the left side of the pedestal member 101, and the front surface of the lower plate unit 15. It is formed in a shape that is inclined downward toward the side. For this reason, when the front frame 14 is opened, even if the game ball falls on the part of the ball launching unit 90, the game ball does not enter the back side of the lower dish unit 15 and flows out to the front side. .

  As shown in FIG. 8, the front surface of the opening / closing member 102 is provided with an introduction port 102b for introducing a game ball guided from the upper plate 201 at the left end of the front view, from which the game ball is introduced. Is introduced to the back side of the opening / closing member 102. As shown in FIG. 11, a lid member 103 is detachably attached to the back surface side of the opening / closing member 102, and the lid magnet 103 covers the electromagnet 104 and the delivery member 105. The electromagnet 104 and the delivery member 105 are members that operate to send out the game balls one by one. As shown in FIG. 12, the electromagnet 104 is placed upside down in the accommodation space recessed in the opening / closing member 102. They are arranged side by side.

  The delivery member 105 is a resin member that is pivotally supported by a pin so that one side of the introduction port 102b can swing up and down with respect to the opening / closing member 102, and only one game ball is provided on one side of the introduction port. A holder portion 105a that is recessed so as to be accommodated is provided. A metal piece 106 is attached to the upper side portion connecting the shaft portion through which the pin is inserted and the holder portion 105 a so as to face the electromagnet 104.

  When the electromagnet 104 is turned on (excited), the metal piece 106 is pulled so as to stick to the electromagnet 104, and the delivery member 105 rotates upward. When game balls are continuously introduced from the introduction port 102b, the top game ball is accommodated in the holder portion 105a and the vertical movement is restricted, and the subsequent game balls are supported by the game ball accommodated in the holder portion 105a. The flow is regulated.

  When the electromagnet 104 is turned off (de-energized) in a state where the game ball is accommodated in the holder portion 105a, the delivery member 105 rotates downward by its own weight, and the game ball accommodated in the holder portion 105a flows downward. To do. At this time, since the transition of the subsequent game ball to the holder portion 105 a is restricted by the upper side of the delivery member 105, only one ball accommodated in the holder portion 105 a is sent downward by the vertical movement of the delivery member 105. The game ball sent out downward is guided onto the firing rail 93 via a delivery port 102c (see FIG. 11) formed by the opening / closing member 102 and the lid member 103. Therefore, when excitation and de-excitation of the electromagnet 104 are repeated, the game balls are guided one by one onto the launch rail 93 in synchronization with the repetition, and the launch solenoid 92 is excited in synchronization with the on / off of the electromagnet 104. Thus, the game balls on the launch rail 93 can be launched one by one toward the game area.

  Next, the passage forming member 36 provided on the front side of the inner frame 13 will be described with reference mainly to FIG. The passage forming member 36 includes a lower tray discharge passage (not shown) for discharging the game balls to the lower plate 301 when the upper plate 201 is full, and a foul ball for discharging the foul balls to the lower plate 301. This is a member for forming a passage (not shown). Here, the foul ball means a game ball that returns to the launch rail 93 side without reaching the entrance of the game area where the return ball prevention member 68 is located because the launch force (launch force) at the time of launch is weak. Yes.

  A gap of about 40 mm is formed between the launch rail 93 and the rails (guidance rails) 61 and 62 on the front surface of the game board 16, and a foul ball passage is provided below the gap. A passage forming member 36 made of a transparent resin is fixed to the mounting surface 30f of the inner frame base 30 with a screw on the front surface of the inner frame 13 and on the left side of the ball launching unit 90. The passage forming member 36 is provided with a groove opened toward the mounting surface 30f side of the inner frame 13, and a foul ball passage is formed by the groove and the mounting surface 30f of the inner frame base 30. The foul ball passage joins a lower tray discharge passage that guides game balls overflowing from the upper plate 201 from the middle to the lower plate 301. A lower tray discharge port 36a that protrudes in a cylindrical shape from the mounting surface 30f toward the front side of the inner frame base 30 is provided at the most downstream portion of the lower tray discharge passage. Is discharged to the lower plate 301 from the lower plate discharge port 36a.

  In the middle of the discharge passage, a full tank sensor (not shown) for detecting that the lower tray 301 is full of game balls is provided so as to form a part of the bottom surface of the passage. When a large amount of game balls are paid out in a short period of time, game balls start to accumulate in the lower plate 301 after the upper plate 201 is full. After that, even if the game balls continue to be paid out, if the game balls in the lower plate 301 are not pulled out, the game balls will start to collect in the discharge passage. This is stopped by the control of the payout and emission control device 611 (see FIG. 25). If the game ball continues to be paid out even if the discharge passage is full, the lower plate 301 overflows and it becomes difficult to continue the game, or the game ball is clogged in the gear for paying out the game ball, causing the failure This is because problems are likely to occur. Further, when a full tank is detected in the discharge passage, an error message “please remove the ball” is repeatedly output from the speaker SP (see FIG. 2) under the control of the payout launch control device 611. The player can be shown that the game balls have accumulated in the lower plate 301, and can be prompted to take out the game balls from the lower plate 301.

  An upper tray discharge port 36b for discharging game balls to the upper plate 201 is provided at the upper left part of the passage forming member 36, and the inner frame base 30 is used for paying out game balls to the upper plate discharge port 36b. There is a payout exit. The payout outlet of the inner frame base 30 connects the back surface and the front surface of the inner frame base 30 and is connected to a payout device 658 (see FIG. 22) provided on the back surface side of the inner frame 13. The payout opening and the upper tray discharge port 36b communicate with the upper plate 201 in a state where the front frame 14 is closed, and the game ball is discharged (discharged) to the upper plate 201 through the discharge port and the upper plate discharge port 36b. . An open / close shutter 37 is attached to the upper plate discharge port 36b. When the front frame 14 is opened (the state shown in FIG. 2), the shutter 37 closes the upper plate discharge port 36b by an urging force such as a spring. . When the front frame 14 is closed, the shutter 37 is tilted and pushed open toward the inner frame base 30 by a ball passage rod 241 (see FIG. 2) provided on the back surface of the front frame 14. Therefore, in this pachinko machine 10 in which the front decorative frame is omitted and the upper plate 201 is directly provided on the front frame 14, the game ball passing through the payout opening of the inner frame base 30 is opened when the front frame 14 is opened. Inconveniences such as spilling on the front surface of 13 can be prevented.

  On the lower side of the lower plate discharge port 36a in the passage forming member 36, a rib 36c having a length contacting the lower surface of the inner frame 13 is provided, and the mounting surface 30f of the inner frame base 30 formed in a flat plate shape is reinforced. Has been. In addition, a gap through which the wiring passes is provided between the rib 36c and the mounting surface 30f, and the rib 36c is used as a holder for electrical wiring.

  A relay board 38 is accommodated in the lower left corner of the front surface of the inner frame base 30. On the relay board 38, wiring of electrical components (touch sensor and variable resistor inside the operation handle 310 and the speaker SP) provided in the lower tray unit 15 and a control device (payout launch control) provided on the inner frame 13 side are provided. It is a part which connects the apparatus 611 and the audio | voice lamp control apparatus 562), and the insertion port (not shown) connected with the connector provided in the wiring cord front end by the side of the lower pan unit 13 is provided. Since the electrical connection between the lower tray unit 15 and the inner frame 13 is gathered on the relay board 38, the wiring work when assembling and removing the lower tray unit 15 is simplified, and the pachinko machine 10 is assembled and Disassembly is easy. In addition, the relay board 38 is provided with a switch for adjusting the volume of the speaker SP in two levels, so that the volume can be easily adjusted without opening the inner frame 13. The wiring from the relay board 38 to the control device provided on the back side of the inner frame 13 is arranged along the lower end of the mounting surface 30f of the inner frame base 30 and on the inner side of the rib 36c of the passage forming member 36. The inner frame base 30 is routed around the back surface of the inner frame 13 through a wiring hole 30 h formed in the lower right corner of the front surface.

  Next, the configuration of the front frame 14 will be described with reference to FIGS. 1, 2, 13, and 14. FIG. 13A is a rear view of the front frame 14, and FIG. 13B is a cross-sectional view taken along the line RR in FIG. 13A. FIG. 14 is a cross-sectional view of the outlet of the upper plate 201 that sends out the game ball to the ball launching unit 90. FIG. 14 (a) shows the state in which the front frame 14 is opened. 14 (b) shows a state in which the front frame is closed.

  The front frame 14 is mainly configured by a front frame base 200 made of ABS resin formed in a rectangular shape, and the front frame base 30 has a central portion so that most of the game area can be visually recognized from the outside. A window portion 14c having an elliptical opening is provided. Moreover, as shown in FIG. 1, the upper plate | board 201 as a ball receiving tray is integrally provided under the window part 14c. The upper plate 201 temporarily stores the game balls and guides them to the ball launch unit 90 while aligning them in a row. 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, and an upper plate is provided on the front decorative frame, but in this embodiment, the front decorative frame is omitted, An upper plate 201 is provided directly on the frame 14. This is because the front frame 14 of the present embodiment includes a window portion 14c that is largely oval so that a game area formed larger than a conventional pachinko machine can be visually recognized from the outside. The upper plate 201 is integrated with the front frame 14 so as to improve the strength of the plate as much as possible. Similar to the lower plate 301, the upper plate 201 has at least a surface layer formed of flame-retardant ABS resin.

  The window portion 14c of the front frame 14 has a vertically elongated elliptical 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. Since the front frame base 30 forming the window portion 14c is formed longer in the vertical direction than in the horizontal direction, the front frame base 30 has a narrow width that is easily broken at the top, bottom, left and right of the front frame base 200 while opening the window portion 14c. The part which becomes can be provided comparatively widely, and it is easy to ensure intensity | strength. In addition, you may form in the linear form, without curving the substantially center part of the left-right side of the window part 14c.

  In the present embodiment, the upper end of the opening of the window portion 14c coincides with the uppermost portion of the outer rail 62 (the upper end of the game area), and the shortest distance between the upper end of the opening and the upper end of the front frame 14 (the so-called upper frame portion). The vertical width is about 50 mm. Compared to the prior art having an upper frame width of about 85 mm to 95 mm, the upper frame width is remarkably shortened, so that it is easy to secure the upper area of the game area and the large variable display device unit 80 can be disposed relatively upward. The distance from the upper end of the front frame 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.

  Also, the shortest distance between the left end of the window portion 14c and the left end of the front frame 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. 13A), that is, 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 14 itself. In the state where the front frame 14 is closed, the frame width on the opening / closing axis side is set wide so that the left end portion of the outer rail 62 is covered and hidden by the left frame portion of the front frame base 200. For this reason, the outer rail 62 is overlapped with the left side frame portion of the front frame 14 when viewed from the front of the pachinko machine 10, and it is difficult to visually recognize the game ball in front of the entrance of the game area. Here, since the player visually recognizes the game balls showing various behaviors in the game area and enjoys the ball game, even if it is difficult to visually recognize the game ball before entering the game area, there is nothing in the actual game. There will be no hindrance. Therefore, sufficient strength and support strength of the front frame 14 can be ensured without hindering the game. Incidentally, the distance in the left-right direction between the left end position of the outer rail 62 and the left end position of the outer frame 12 when viewed from the front of the pachinko machine 10 is about 30 mm, the right end position of the game area (the inner right end position of the arc member 70) and the outer frame. The distance in the left-right direction from the right end position of 12 is about 45 mm.

  In addition, the front frame 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means change the light emission mode by turning on or blinking according to the change of the game state at the time of big hit, predetermined reach or the like, and play a role of enhancing the effect effect during the game. As shown in FIG. 1, on the upper side of the window portion 14 c and on both the left and right sides thereof, electrical decoration portions 202 to 204 having built-in light emitting means such as LEDs are provided along the peripheral edge of the window portion 14 c. In the pachinko machine 10, these lighting parts 202 to 204 function as stage lamps such as jackpot lamps, and the lighting parts 202 to 204 are turned on by lighting or blinking of the built-in LEDs at the time of jackpot or reach stage. Alternatively, it flashes to notify that the jackpot is being hit or that the reach is one step before the jackpot.

  Further, as shown in FIG. 1, a prize ball lamp 205 that is turned on while awarding a prize ball is provided in the upper right part of the front frame 14 as viewed from the front. An error display lamp 206 that is turned on when an error occurs is provided. In addition, a small window 207 is formed on the lower side of the right illumination part 204 by attaching a transparent resin from the back side of the front frame base 200 so that the back side of the front frame 14 can be seen. A stamp or the like stuck on the sticking space K1 (see FIG. 3) is visible from the front surface of the pachinko machine 10. In addition, in the pachinko machine 10, a plated member 208 made of ABS resin that is chrome-plated is attached to an area around the electric decoration parts 202 to 204 in order to bring out more gorgeousness. For this chrome plating, trivalent chromium is used in consideration of the production environment and the like, instead of hexavalent chromium which has been widely used conventionally.

  As shown in FIG. 1, a lending operation unit 210 is disposed below the window 14c. The ball lending operation unit 210 is provided with a frequency display unit 211, a ball lending button 212, and a return button 213. When the lending operation unit 210 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. Specifically, the frequency display unit 211 is an area in which the remaining amount information such as a card is displayed, and the built-in LED is lit to display the remaining amount as the remaining amount information. The ball lending button 212 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 201 as long as there is a remaining amount on the card or the like. Is done. The return button 213 is operated when requesting the return of a card inserted into the card unit. In addition, in the pachinko machine in which game balls are rented directly from the ball lending device or the like to the upper plate without using a card unit, so-called cash machine, the ball lending operation unit 210 is unnecessary. It is also possible to add a decorative seal or the like to the installation portion of the parts so that the component configuration is common. A pachinko machine using a card unit and a cash machine can be shared.

  In the upper right corner on the back side of the front frame 14, as shown in FIG. 13A, a light emitting substrate 214 for LED as a light emitting means is attached to the back surface of the front frame base 200 with screws. Further, various reinforcing members made of metal are provided on the back side of the front frame 14 so as to surround the window portion 14c. Specifically, metal reinforcing plates 221 to 224 are respectively attached to the back side of the front frame 14 and on the upper and lower, left and right outer sides of the window portion 14c. These reinforcing plates 221 to 224 are connected in contact with each other to increase the rigidity and strength of the front frame 14 which has been reduced by the formation of the window portion 14c. Further, the right reinforcing plate 221 is disposed so as to overlap the rear surface side of the light emitting substrate 214 described above, but in order to avoid direct contact between them or to prevent the light emitting substrate 214 from being energized. A transparent synthetic resin cover plate 215 is provided between the reinforcing plate 221 and the light emitting substrate 214. Even if noise or a magnetic field is generated around the reinforcing plates 221 to 224 due to the charging, the influence on the light emitting substrate 214 is reduced by the cover plate 215, and malfunctions and failures are suppressed. . Part of the reinforcing plates 221 to 224 is grounded (not shown) so that the reinforcing plates 221 to 224 are difficult to be charged.

  The reinforcing plate 221 on the right side of the back surface of the front frame 14 is provided with an engaging claw 221a (see FIG. 2) having a hook shape at an intermediate position. The engaging claw 221a is configured to enter a groove 30j formed in the inner frame 13 (inner frame base 30) with the front frame 14 closed. As shown in FIG. 7, a metal stop plate 39 is screwed to the inner frame base 30 so as to cover a part of the groove 30 j, and the front frame 14 is closed with respect to the inner frame 13. In this state, the tip of the engaging claw 221a enters the back side of the retaining plate 39 shown in FIG. Thereby, the front frame 14 can be prevented from being lifted at an intermediate position on the left side when viewed from the front of the pachinko machine 10, the upper plate 201 is provided on the front frame 14, and the front frame 14 is configured to be large in the vertical direction. Even if the (positions of the support brackets 33 and 34) are largely separated from each other, an illegal act with the front frame 14 floating can be suppressed.

  On the reinforcing plate 222 on the left side of the rear surface of the front frame 14, a pair of upper and lower front frame flange portions 14 a that protrude from the rear surface side of the front frame 14 and are formed in a bowl shape are integrally formed. The front frame 14 is locked by engaging the front frame collar 14 a with the front frame collar 411 of the locking unit 410 provided on the back side of the inner frame 13. The front frame 14 in the locked state is unlocked by performing a predetermined unlocking operation on the cylinder lock 420 with a dedicated key, and is in a state where it can be opened.

  A screw hole through which the screw 225 is inserted is provided in a central portion in the left-right direction of the reinforcing plate 223 on the upper back side of the front frame 14, and a tip portion of the screw 225 is, as shown in FIG. It is screwed to a plating member 208 provided on the front side of the front frame 14, and the plating member 208 is grounded through a screw 225 and a reinforcing plate 223. Therefore, even if decorative plating is applied to the front side of the front frame 14, problems due to charging and noise caused by the charging can be suppressed.

  As shown in FIG. 2, a resin-made rail side wall member 226 is provided on the reinforcing plate 224 below the back surface of the front frame 14 at a position facing the firing rail 93. The rail side wall member 226 functions as a side wall of the launch rail 93 when the front frame 14 is closed so that the game ball does not spill from the launch rail 93. Further, on the right side of the rail side wall member 226, a ball passage rod 241 that protrudes from the back surface side of the front frame 14 so as to be continuous with the hole connected to the upper plate 201 is fixed to the front frame base 200 with a screw. When the front frame 14 is closed, the ball passage rod 241 pushes the shutter 37 (see FIG. 2) on the inner frame 13 side to form a game ball flow path to the upper plate 201.

  As shown in FIG. 13A, a ball outlet 224a formed by opening a part of the lower reinforcing plate 224 in a square shape is provided on the rear side of the front frame 14 on the left side of the rail side wall member 226. An opening / closing unit 230 is provided on the upper side of the ball outlet 224a. The opening / closing unit 230 closes the ball outlet 224a when the front frame 14 is opened. The ball outlet 224a is provided in the most downstream portion of the upper plate 201, and communicates the upper plate 201 and the introduction port 102b (see FIG. 9) of the ball launch unit 90 when the front frame 14 is closed. The game ball placed on the upper plate 201 is guided to the introduction port 102b of the ball launch unit 90 via the ball outlet 224a.

  Here, the structure of the opening / closing unit 230 will be described with reference to FIG. The opening / closing unit 230 includes a housing 231 as a case member screwed to the lower reinforcing plate 224 and an upper end accommodated in the housing 231, and the other portions are arranged downward along the lower reinforcing plate 224. A thin plate-like shielding plate 232 that extends and a rotation lever 233 made of hard resin that is rotatably fixed to the upper surface of the shielding plate 232 while being pivotably supported on the inner surface of the housing 231. ing. The opening / closing unit 230 is integrated with the housing 231 by assembling the shielding plate 232 and the rotating lever 233, and facilitates and simplifies the assembling work on the front frame 14 side.

  The rotation lever 233 is pivotally supported by the housing 231 about a rotation shaft 231a provided on the inner surface of the housing 231 substantially parallel and substantially horizontally to the lower reinforcing plate 224. The rotation lever 233 has a plate support portion 233a extending from the rotation shaft 231a toward the reinforcing plate 224 (left side in FIG. 14A), and extending downward from the rotation shaft 231a. In addition, a contact portion 233b that protrudes out of the housing 231 is provided so as to contact a part of the inner frame 13 when the front frame 14 is closed. The inner frame base 30 is provided with a protrusion 30k (see FIG. 7) that protrudes from the attachment surface 30f to the front surface, and the contact portion 233b is provided so as to contact the protrusion 30k. Since the contact portion 233b extends in a direction substantially perpendicular to the opening / closing direction of the front frame 14 (the left-right direction in FIG. 14A) with respect to the rotation shaft 231a, the contact portion is closed when the front frame 14 is closed. When the 233b is pressed by the inner frame 13, the rotation lever 233 is easy to rotate, and the operation over a long period of use is ensured.

  The shielding plate 232 is formed of an elastic thin plate-like metal piece (for example, a stainless steel thin plate), and one end is fixed to the plate support portion 233a (the end on the front frame 14 side) of the rotating lever 233, The lower end 232a which is the other end is a free end. The lower end 232a of the shielding plate 232 is formed wider than the ball outlet 224a, as shown in FIG. Therefore, the ball outlet 224a is reliably covered by the lower end portion 232a of the shielding plate 232 so that the elastic deformation in the middle portion of the shielding plate 232 is facilitated and the operation resistance is lowered, and the outflow of the game ball from the ball outlet 224a is prevented. The shielding plate 232 can surely prevent it. Note that the width of the lower end 232a may be narrower than the ball outlet 224a. However, it is preferable that the lower end 232a has a width equal to or larger than the same in order to prevent an erroneous outflow of the game ball. It is preferable to widen the width of 232a.

  If the lower end 232a of the shielding plate 232 is narrower than the ball outlet 224a, the shielding plate 232 enters the ball outlet 224a, the lower end of the shielding plate 232 collides with the game ball in the ball outlet 224a, and the shielding plate 232 is deformed. And damage is likely to occur. In the pachinko machine 10, since the lower end portion 232a of the shielding plate 232 is wider than the ball outlet 224a, the shielding plate 232 does not enter the ball outlet 224a, and the shielding plate 232 is brought into contact with the game ball. Deformation and breakage are prevented.

  Here, on the lower side of the ball outlet 224a, as shown in FIG. 14 (a), a passage leading from the upper plate 201 to the lower plate 301 and a closing plate 234 for closing the passage are provided. 234 is movable to the front side of the pachinko machine 10 (left side in FIG. 14A). When the closing plate 234 moves to the front side, the upper plate 201 and the lower plate 301 communicate with each other, and the game ball flows down to the lower plate 301. In this case, if the lower end portion 232a of the shielding plate 232 is narrower than the bulb outlet 224a, the lower end portion 232a may enter the bulb outlet 224a to cause clogging. By forming the lower end 232a of the shielding plate 232 wider than the ball outlet 224a, the communication between the upper plate 201 and the lower plate 301 can be ensured, and the occurrence of clogging of the ball can be suppressed.

  The shielding plate 232 of the opening / closing unit 230 is supported by the reinforcing plate 224 and the plate support portion 233a of the rotating lever 233 in a state where a flat thin plate is elastically deformed and bent downward. For this reason, the shielding plate 232 is in a state of pressing the reinforcing plate 224 so as to return to the original flat state by the elastic force. When the front frame 14f is in the open state (the state shown in FIG. 14A), the ball outlet 224a is closed while being pressed by the shielding plate 232, and the game ball is prevented from flowing out.

  When the front frame 14f is in the open state, as shown in FIG. 14A, the front end side (lower end side) of the contact portion 233b of the rotating lever 233 faces the back side of the front frame 14 (right side in FIG. 14A). Projecting. In this state, the rotation lever 233 is such that the contact portion 233b protrudes behind the front frame 14 around the rotation shaft 231a due to the elastic force of the shielding plate 232 returning to flat (FIG. 14 ( a) (counterclockwise direction), and stops at a position (first rotation position) in contact with a part of the housing 231 (stopper portion 231b).

  In the state where the rotation lever 233 is disposed at the first rotation position, the shielding plate 232 is in a state where it is suspended to a position where the lower end portion 232a closes the upper portion of the bulb outlet 224a. In this state, the flow of the game balls in the upper plate 201 is restricted by the shielding plate 232, and the game balls do not flow out from the ball outlet 224 a to the back side of the front frame 14. Therefore, even if the front frame 14 is opened while the game balls are stored in the upper plate 201, the game balls in the upper plate 201 can be prevented from flowing out by the shielding plate 232.

  Further, the housing 231 is provided with a pressing portion 231c that abuts against a portion between one end portion and the lower end portion 232a of the shielding plate 232 supported by the rotating lever 233 and presses the shielding plate 232 in the direction of the reinforcing plate 224. It has been. For this reason, the shielding plate 232 is more strongly pressed toward the reinforcing plate 224, so that the game ball is guided to the ball outlet 224a vigorously or there is a large amount of game balls in the upper plate 201 and the shield plate 232 is opened. Even when the force increases, the game ball is more reliably received and the outflow of the game ball from the ball outlet 224a is surely prevented.

  When the front frame 14 is closed from the state shown in FIG. 14A, the contact portion 233b of the rotating lever 233 is pressed while contacting the projection 30k of the inner frame 13, as shown in FIG. 14B. To the front frame 14 side. Thereafter, as the front frame 14 is closed, the pivot lever 233 pivots in the direction entering the housing 231 from the first pivot position shown in FIG. 14A (clockwise direction in FIG. 14B). When the front frame 14 is completely closed (that is, the front frame collar portion 14a is engaged with the front frame collar member 412 of the locking unit 410), the position is pushed into the housing 231 to the maximum (second position). ). As the rotation lever 233 rotates, the plate support portion 233a of the rotation lever 233 moves to the side (upper side) away from the ball outlet 224a.

  In a state in which the rotation lever 233 is disposed at the second rotation position, the shielding plate 232 is further distorted along the plate surface of the reinforcing plate 224 while the plate support portion 233a of the rotation lever 233 is raised. Slide upward. The lower end 232a of the shielding plate 232 that has covered the ball outlet 224a rises to a position where the game ball can pass through the ball outlet 224a. If there is a game ball in the upper plate 201, the game ball will sequentially flow out from the ball outlet 224a toward the introduction port 102b of the ball launch unit 90. Therefore, as long as game balls are continuously supplied to the upper plate 201, the game balls can be continuously fired toward the game area by the ball launch unit 90.

  When the front frame 14 is released from the closed state, the rotation lever 233 (contact portion 233b) is released from the pressing by the protrusion 30k of the inner frame 13, and is restored from the second rotation position by the restoring force of the shielding plate 232. Displacement to the 1 rotational position. With the displacement of the turning lever 233, the shielding plate 232 slides down on the plate surface of the reinforcing plate 224, the ball outlet 224a is closed at the lower end 232a of the shielding plate 232, and the game ball from the ball outlet 224a Is prevented from flowing out. That is, since the ball outlet 224a is closed with the opening of the front frame 14, the store clerk at the game hall is worried about the outflow of the game ball in the upper plate 201 when the front frame 14 is opened and an operation such as inspection is performed. The front frame 14 can be easily opened without any problems.

  Next, the glass unit 17 attached to the back surface of the front frame 14 will be described with reference to FIGS. FIG. 15 is a front view of the glass unit 17. 16 is a cross-sectional view taken along line Sa-Sa in FIG. 15, FIG. 17 is a cross-sectional view taken along line Sb-Sb in FIG. 15, and FIG. 18 is a cross-sectional view taken along line Sc-Sc in FIG. It is. FIG. 19 is a partially enlarged view of the glass unit 17 as seen from the direction of the arrow V in FIG.

  The glass unit 17 in the present embodiment is not formed by attaching rectangular plate glasses to the front frame separately in front and rear pairs as in the prior art, but as a whole, two plate glasses 151 having a round shape are integrated (assembled). And then attached to the front frame 14. The glass unit 17 substantially corresponds to the shape of the window portion 14c (see FIG. 1) of the front frame 14 and is provided so as to surround a pair of front and rear plate glasses 151 that are substantially circular and have the same shape, and the periphery of the plate glasses 151. The holding frame 153 is provided.

  The holding frame 153 is formed of ABS resin, and is formed in an annular shape along the outer shape of the plate glass 151 with a substantially “h” -shaped cross section as shown in FIG. 16. For this reason, on both sides of the holding frame 153 (upper and lower sides in FIG. 16), a holding portion for the plate glass 151 formed in a pair of bowl-shaped cross sections is formed. The outer peripheral edge on one surface side is disposed in contact with the holding frame 153. The holding frame 153 and the plate glass 151 are respectively bonded and fixed by an adhesive (bonded with a hot-melt adhesive or the like), and the two plate glasses 151 are integrated with a predetermined interval by a holding frame 153 interposed therebetween. It becomes.

  As shown in FIG. 15, the holding frame 153 is formed in a shape bulging outward on one side (the lower left side in FIG. 15), and a part of the plate glass 151 is also swelled so as to cover the bulged portion. The shape is out. This bulging portion serves as a cover that covers a part of the guide rail formed by the outer rail 62 and the inner rail 61 on the surface of the game board 16 (the lower left portion in FIG. 3), and the front surface of the game board 16 in the guide rail portion. The outflow of game balls to the side is regulated.

  In addition, the holding frame 153 is provided with a partition wall 153a that divides an area between the two glass sheets 151 in a portion that bulges outward on one side (lower left side in FIG. 15). A storage portion 154 is formed between the two plate glasses 151 by the partition wall 153a, and a drying tool 155 that absorbs moisture is provided in the storage portion 154 in order to prevent moisture condensation and fogging. The drying tool 155 is composed of a casing that forms a housing space inside with a pair of two case members facing each other, and a desiccant on the grains housed in the casing. The casing is partitioned into a plurality of rooms by partition walls (not shown), and a desiccant is accommodated in each room. Examples of the desiccant include zeolite and silica gel. The casing is formed with a large number of small holes communicating with the inside and outside of the casing, and the air in the space sealed or almost sealed by the two glass sheets 151 is efficiently dehumidified to prevent the occurrence of condensation. It has become so. The partition wall 153a and the drying tool 155 of the holding frame 153 are disposed on the outer peripheral side of the opening formed by the window portion 14c of the front frame 14, and the drying tool 155 and the like unnecessary for decoration of the pachinko machine 10 are externally provided. Is not visible.

  As shown in FIG. 17, the holding frame 153 is provided with an escape hole 153 b that communicates the internal space surrounded by the two plate glasses 151 and the holding frame 153 with the outside. This escape hole 153b is provided in order to make the bonding and fixing of the plate glass 151 easy and reliable. Adhesive is injected into the entrance of the escape hole 153b, dried and hardened. Further, the inner shape of the escape hole 153b is formed in a tapered shape (conical shape) in which the inner diameter gradually decreases from the outside (the lower side of FIG. 15) to the inside of the holding frame 153, and when the adhesive is injected from the outside. The escape hole 153b is easily blocked.

  Here, the assembling process of the glass unit 17 will be described with a focus on the portion where the two glass plates 151 are bonded and fixed to the holding frame 153 in particular. One plate glass 151 is placed, and the holding frame 153 is bonded and fixed to the plate glass 151. Next, after the drying tool 155 is set in the housing portion 154, the second sheet glass 151 is bonded and fixed to the holding frame 153.

  The second sheet glass 151 is pressed with a strong force in order to make the bonding more reliable. However, the air between the two sheet glasses 151 may be compressed during the pressing. If the air is strongly compressed, there is a concern that the plate glass 151 may be peeled off from the holding frame 153 after bonding due to the expansion of the air. In this respect, in the present embodiment, air can enter and exit between the glass plates 151 and the outside through the escape holes 153b, so that the air is compressed even if the second glass plate 151 is pressed during adhesion fixing. In other words, the situation that the plate glass 151 is peeled off from the holding frame 153 due to the expansion of air does not occur.

  After the two plate glasses 151 are bonded to the holding frame 153, an adhesive is injected into the escape hole 153b and dried and cured after a certain time. As a result, a sealed space is formed between the glass plates 151, and the intrusion of moisture, dust, etc. is restricted, and the hygroscopic effect by the drying tool 155 is enhanced to improve the visibility of the game area. it can.

  The holding frame 153 is provided with mounting portions 153c that protrude outward at a plurality of locations on the periphery thereof. Each attachment portion 153c is formed in the same shape, and each attachment portion 153c is provided with an insertion hole 153d along the surface direction of the plate glass 151 as shown in FIG. Further, a metal plate 161 as a thin washer having a small-diameter hole 161a at a position corresponding to the insertion hole 153d is held on one surface (the upper surface in FIG. 18) of the attachment portion 153c by a small screw 162. It is fixed to the frame 153. Further, an attachment screw 163 for attaching the glass unit 17 to the front frame 14 is provided so as to be inserted into the insertion hole 153d and the small diameter hole 161a of the metal plate 161.

  As shown in FIG. 18, the mounting screw 163 includes a shaft portion 163a formed in a cylindrical shape with a smooth surface, a male screw portion 163b integrally formed on the distal end side of the shaft portion 163a, and a proximal end side of the shaft portion 163a. It is formed by the operation part 163c provided in this. The shaft portion 163a is formed to have a smaller diameter than the small diameter hole 161a of the metal plate 161, while the operation portion 163c is formed to be larger. The male screw portion 163b has substantially the same outer diameter as the small-diameter hole 161a of the metal plate 161, and has an outer diameter larger than that of the small-diameter hole 161a and a smaller valley diameter. For this reason, the mounting screw 163 can be mounted by screwing the male screw portion 163b into the small diameter hole 161a of the metal plate 161, and can be moved through the length of the shaft portion 163a (stroke amount) through the metal plate 161. Thus, the holding frame 153 cannot be removed.

  As shown in FIG. 19, the operation portion 163c of the mounting screw 163 is formed in a cylindrical shape having a diameter larger than that of the shaft portion 163a, and the outer peripheral surface thereof is processed to be jagged by a fine groove 163c2 extending in the axial direction. In addition, a cross-shaped groove 163c1 is provided at the center of the end surface of the operation portion 163c, and the mounting screw 163 can be rotated by a tool such as a Phillips screwdriver. For this reason, even if the outer peripheral surface of the operation part 163c is grasped with a fingertip, even if a predetermined tool is inserted into the cross-shaped groove 163c1, the attaching screw 163 can be rotated. Therefore, the attachment / detachment operation of the glass unit 17 can be performed without a tool, and can be performed more easily and reliably when there is a tool. Although the mounting screw 163 is screwed into the metal plate 161 and cannot be removed from the holding frame 153, the mounting screw 163 has a small diameter hole 161a in the metal plate 161 larger than the outer diameter of the male screw portion 163b. May be easily removable. Further, a locking washer such as a spring washer may be provided between the mounting screw 163 (operation unit 163c) and the metal plate 162. Further, the outer diameter shape of the operation portion 163c is not limited to the above-described shape, and may be formed so as to be easily rotated by hand, for example, a so-called thumb screw having portions protruding in a plate shape on both sides of the shaft. good.

  On the back side of the front frame 14, as shown in FIG. 13A, a to-be-attached tool 227 in which female screws are formed at a plurality of locations corresponding to the mounting portion 153 c provided in the glass unit 17 is provided. The fixture 227 is a metal member that is formed in a boss (cylindrical) shape and has an internal thread on which an attachment screw 163 can be screwed, and is screwed or press-fitted into a predetermined position of the front frame base 200. Each is fixed. The glass unit 17 is attached and fixed to the back surface of the front frame 14 by fixing the attachment portions 153 c to the attachments 227 with the attachment screws 163.

  Further, on the back side of the front frame 14, as shown in FIG. 2, three ribs 200 a to 200 c protruding to the back side along a part of the outer peripheral shape of the holding frame 153 are integrally formed with the front frame base 200. Has been. The lower ribs 200b and 200c are provided so as to protrude larger than the upper rib 200a at the two lower portions of the window portion 14c of the front frame base 200. To assist. The upper rib 200a and the lower rib 200c are integrally formed with a locking projection that protrudes toward the center of the window portion 14c at the leading end of each rib in the protruding direction. At the time of attachment, the glass projection 17 can be temporarily fixed by fitting the engaging protrusion into a recess provided on the outer peripheral edge of the holding frame 153.

  Next, returning to FIG. 13A, the configuration of the front frame 14 will be described. Support metal fittings 228 and 229 are attached at two upper and lower positions as a support mechanism of the inner frame 13 on the right side end portion of the rear surface of the front frame 14 (left end portion in front view of the pachinko machine 10). The front frame 14 is releasably attached to the inner frame 13 by assembling the support brackets 228 and 229 on the front frame 14 side to the support brackets 33 and 34 (see FIG. 7) on the inner frame 13 side.

  More specifically, the support bracket 228 on the upper side of the front frame 14 has a substantially rod shape, and is formed in a stepped columnar shape whose upper diameter is thicker than the lower diameter. The support bracket 33 on the upper side of the inner frame 13 is provided with a support hole 33a having a notch opened on the front side of the inner frame 13 as described above. 14 is narrower than the upper diameter of the upper support fitting 228 and wider than the lower diameter. Therefore, when the lower portion (small diameter portion) of the upper support fitting 228 is fitted into the support hole 33a and then the support fitting 228 is slid downward, the large diameter portion of the support fitting 228 is fitted into the support hole 33a. The support fitting 228 cannot be removed from the support hole 33a.

  The lower support bracket 229 on the lower side of the front frame 14 is fixed to the back side of the front frame 14 with screws, and is formed by bending from the back side to the lower end surface. The support fitting 229 is provided with a support hole 229a that opens upward at the lower end surface of the front frame 14, and the support hole 229a has a protruding shaft formed by the support fitting 34 on the inner frame 13 side. The front frame 14 is rotatably supported with respect to the inner frame 13.

  As a procedure for mounting the front frame 14 to the inner frame 13, first, the lower portion (small diameter portion) of the support fitting 228 on the upper side of the front frame 14 is inserted into the support hole 33a through the notch. Next, the front frame 14 is slid downward after the support hole 229a on the lower side of the front frame 14 is positioned on the protruding shaft 34a of the support fitting 34 on the lower side of the inner frame 13. The support metal 228 on the upper side of the front frame 14 has a large-diameter portion fitted into the support hole 33a so that it cannot be removed. Installation is complete.

  Next, the lower plate unit 15 will be described with reference mainly to FIGS. 20 is a front view of the lower plate unit 15, and FIG. 21 is a rear view thereof. The lower plate unit 15 is obtained by attaching a lower plate 301, an operation handle 310, and the like to an ABS resin lower plate base 300 formed in a horizontally long rectangular shape.

  As shown in FIG. 20, the lower plate unit 15 is provided with a lower plate 301 as a ball receiving plate at a substantially central portion, and is discharged from the lower plate discharge port 36a (see FIG. 2) on the inner frame 13 through the discharge port 301a. The played game balls are configured to be stored in the lower plate 301. The lower plate 301 is formed by sticking a flame retardant ABS resin formed as a separate component to the lower plate base 300 to the surface. Although it is not necessary to form all of the lower plate 301 with flame-retardant ABS resin, at least the surface portion of the lower plate 301, that is, the surface layer of the lower plate 301 and the front panel 302 at the back of the lower plate 301 are made of ABS resin. It is preferable to form. Since there is a danger that the lit cigarette is left in the lower plate 301, damage to the pachinko machine 10 and the occurrence of fire can be suppressed by forming at least the surface portion thereof with flame-retardant ABS resin. It is. The front panel 302 is provided with a number of speaker holes 303 for outputting sound from the speaker SP, and the speaker SP is screwed at a position corresponding to the speaker hole 303 on the back side of the lower plate unit 15. It is fixed by.

  In the lower part of the front of the lower plate 301, a ball removal lever 304 is provided for operating when the game balls stored in the lower plate 301 are discharged downward. The ball pulling lever 304 is always urged to the right, and by sliding it to the left against the urging, the bottom opening formed on the bottom surface of the lower plate 301 is opened. A game ball naturally falls from the bottom opening and is discharged. The operation of the ball pulling lever 304 is normally performed in a state where a box (generally referred to as “a thousand boxes”) for receiving game balls discharged from the lower plate 301 is placed below the lower plate 301.

  As described above, the operation handle 310 is disposed on the right side of the lower plate 301, and the ashtray 305 is attached on the left side of the lower plate 301. The ashtray 305 can be rotated in the front and back directions together with a shaft rotatably attached to the lower tray base 300. A metal sheet metal 306 is provided on the back surface side of the lower plate unit 15 so as to cover the entire back surface, and the rigidity and strength of the lower plate unit 15 itself are increased.

  The lower pan unit 15 is attached to the inner frame 13 so as to be openable and closable. Like the inner frame 13 and the front frame 14, the lower pan unit 15 can be opened to the front side with the left side when viewed from the front of the pachinko machine 10 as an opening / closing axis. Yes. The lower dish unit 15 is provided with a support hole 307 on the upper left side of the front view and a support shaft 308 on the lower left side of the front view. When the support hole 307 and the support shaft 308 of the lower plate unit 15 are assembled to the support fittings 34 and 35 (see FIG. 7) on the inner frame 13 side, the lower plate unit 15 is attached to the inner frame 13 so that it can be opened and closed. Is done.

  The support hole 307 and the support shaft 308 will be described in more detail. The support hole 307 is configured by a hole drilled in a portion where the upper end portion of the sheet metal 306 is folded, and protrudes downward in the support bracket 34 on the inner frame 13 side. The protruding shaft 34b to be inserted can be inserted. The support shaft 307 is configured by a substantially inverted L-shaped protrusion that can be projected and retracted in the vertical direction, and is always maintained in a state of protruding downward by a spring (not shown) covered by the sheet metal 306.

  As a mounting procedure of the lower plate unit 15, first, the protruding shaft 34 b on the inner frame 13 side is inserted into the support hole 307 to fix the upper side of the lower plate unit 15 to the inner frame 13. Thereafter, the support shaft 308 is brought into an immersive state against the biasing force of the spring, and then the tip of the support shaft 308 is aligned with the support hole of the support fitting 35 provided on the lower side of the inner frame 13. When the positions of the support shaft 308 and the support hole match, the support shaft 308 is fitted into the support hole by the biasing force of the spring, and the mounting of the lower dish unit 15 is completed.

  The sheet metal 306 of the lower dish unit 15 is formed with a lower dish engaging portion 15a formed in a substantially rectangular shape and arranged in two upper and lower portions on the left side of the back surface. The lower plate unit 15 is locked by engaging the lower plate engaging portion 15 a with the lower plate hook member 413 of the locking unit 410 provided on the back side of the inner frame 13. The lower plate unit 15 in the locked state is unlocked by performing a predetermined unlocking operation with a dedicated key on the cylinder lock 420 and is in a state where it can be opened.

  Here, the lower plate 301 and the operation handle 310 of the pachinko machine 10 in which the lower plate unit 15 is arranged are conventionally formed as a part of the inner frame 13 and cannot be opened to the front side. 14 up to the lower end of the upper plate 201 formed by the cover 14 is configured to cover the front side of the inner frame 13. On the front side of the inner frame 13 covered with the front frame 14, a game board 16 that forms a game area and a ball launch unit 90 that launches a game ball toward the game area are arranged side by side, When only the front frame 14 is opened forward and the lower plate 301 and the operation handle 310 are not opened, the arrangement position of the ball launching unit 90 is limited to the lower end portion of the upper plate 201, and the game is formed on the upper side. It was difficult to enlarge the area.

  In the pachinko machine 10 according to the present embodiment, since the lower plate unit 15 is configured to be openable to the inner frame 13 in addition to the front frame 14, the ball launch unit 90 is placed on the back side of the lower plate 301 and the operation handle 310. It can be arranged on the lower side so as to overlap, and the game area of the game board 16 can be made larger in the vertical direction accordingly. Moreover, since the lower plate unit 15 can be opened, in addition to the back surface side at the lower end portion of the inner frame 13, various types are provided on each surface of the lower surface portion of the lower plate unit 15 and the front surface side of the inner frame 13 at the lower end portion. Components and wiring can be accommodated, and the degree of freedom in designing the components and wiring is increased. Further, when working on the lower side of the lower plate 301 or the operation handle 310, for example, when removing the ball clogging in the passage connecting the upper plate 201 and the lower plate 301, or on the back side of the lower plate 301 In the case of checking a full tank sensor for detecting a full tank state, the lower tray unit 15 is opened, and the inner frame 13 is fixed to the outer frame 12 so that each of the inner frames 13 can be viewed from the front side of the inner frame 13. Work can be done. When the inner frame 13 is opened, it is difficult to work because the inner frame 13 swings with respect to the outer frame 12, but the work performed on the inner frame 13 by opening the lower tray unit 15 is fixed to the inner frame 13. Since it can be performed in the state where it was done, it becomes a simple thing.

  The inner frame 13, the front frame 14, and the lower plate unit 15 are formed by assembling other members to the respective members (the inner frame base 30, the front frame base 200, and the lower plate base 300) as a base. In this embodiment, the base members 30, 200, 300 are all made of synthetic resin, specifically ABS resin. By forming each of these base members 30, 200, and 300 with a synthetic resin, it is possible to cope with a more complicated shape by forming the base member with metal, and decorations are formed by forming characters, patterns, etc. on the front surface of the pachinko machine 10. While improving the performance, an attachment part or the like of the mating part is integrally formed on the back surface side to reduce the production cost. In addition, since ABS resin is generally inexpensive and has good adhesion such as plating and excellent decorativeness, it is easy to form a decoration subjected to surface treatment at a low cost on the front surface of the pachinko machine 10. In addition, ABS resin has the advantage of high impact resistance, and a player falls and collides with the front surface of the pachinko machine 10, or a player who is dissatisfied with the game results strikes the front surface of the pachinko machine 10. Even so, the ABS resin is suitable as a material for the base members 30, 200, and 300 because the player is less likely to be damaged and the player is injured.

  The base members 30, 200, 300 and the decorative plate 24 of the outer frame 13 are all made of the same material ABS resin. For this reason, when at least two members of the base members 30, 200, 300 and the decorative plate 24 are formed in the same color, the degree of fading or discoloration becomes the same due to deterioration over time. Therefore, it is possible to reduce the difference in chromaticity of the front surface of the pachinko machine 10 composed of a plurality of members over a long period of time and maintain a good quality appearance. In particular, it is preferable that the base members 30, 200, 300 and the decorative plate 24 of the outer frame 13 are made of the same material up to the manufacturer and material grade in order to maintain a good quality appearance.

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

  The members that form the path of the game ball from the tank 655 to the payout path are all formed of a conductive resin material (for example, conductive polycarbonate resin) and grounded (grounded) at a part thereof. Yes. Thereby, generation | occurrence | production of the noise by charging of a game ball is suppressed.

  In addition, as shown in FIG. 35, the back pack 651 is provided with a pair of upper and lower support shafts 685 at the right end thereof, and these support shafts 685 are supported on the support holes 538 on the inner frame 13 side (see FIG. 25). The back pack unit 503 is supported so as to be openable and closable with respect to the inner frame 13. In addition, the back pack 651 is provided with a pair of upper and lower nai latches 686 as fasteners at the left end portion, and is provided with a locking hole 687 at the upper end portion, and the nai latch 686 is connected to the fastening hole 540 ( The back pack unit 503 is fixed to the inner frame 13 so that it cannot be opened and closed by engaging the locking hole 687 with the fixing member 542 (see FIG. 25) on the inner frame 13 side. As shown in FIG. 35, a tank 355 for storing a game ball is provided on the left side of the locking hole 687, and this portion is not used for the fixing tool 542 and the locking hole 687. This is because it is firmly fixed. When the fixture 542 is fixed, the back pack unit 503 is also fixed to the inner frame 13 by the fixtures 541 and 543 (see FIG. 25) at the upper left corner and the lower right corner of the inner frame 13. The support hole portion 538 and the support shaft 685 correspond to the support shaft portion M6 in FIG. 23, the fastened hole 540 and the ny latch 686 correspond to the fastening portion M7, and the fixture 542 and the locking hole 687 correspond to the locking portion M8, respectively. . Further, the fixture 543 corresponds to the locking portion M9.

  Next, a locking device for locking the inner frame 13 to the outer frame 12 and locking the front frame 14 and the lower plate unit 15 to the inner frame 13 will be described with reference to FIGS. 38 to 40. 38 is a front view of the locking unit 410, FIG. 39 is a front perspective view of the locking unit 410, and FIG. 40 is a rear perspective view of the locking unit 410. In addition, in order to avoid complication of drawing, the coil spring is abbreviate | omitted and shown in FIGS. 38-40.

  The locking device is engaged with a locking unit 410 that is vertically long on the back surface of the inner frame 13 and on the right side of the pachinko machine 10 when viewed from the front, and hook members 411 to 413 that are slidably provided on the locking unit 410. And an engaging portion that maintains the inner frame 13 and the front frame 14 in a closed state. As the engaging portion, the metal fitting 23 of the outer frame 12, the front frame flange portion 14a of the front frame 14, and the lower plate engaging portion 15a of the lower plate unit 15 are applicable.

  A cylinder lock 420 having a key hole 421 is provided at the lower center of the locking unit 410 when viewed from the front. The locking of the inner frame 13 and the locking of the front frame 14 are released by inserting a dedicated key into the key hole 421 of the cylinder lock 420 and performing a predetermined operation.

  The locking unit 410 includes an eaves base 414 formed vertically and eaves members 411 to 413 that are slidably provided on the eaves base 414 and engage with the inner frame 13, the front frame 14, and the lower dish unit 15. I have. The eaves base 414 is formed in a substantially L-shaped cross section by an attachment plate 415 in which a plurality of attachment holes are formed, and a support plate 416 that is orthogonal to the attachment plate 415 and supports the eaves members 411 to 413 and the like. The locking unit 410 is fixed to the inner frame 13 by tightening the mounting plate 415 of the flange base 414 with a screw at an end portion on the back surface side of the inner frame 13 and separated from the opening / closing shaft (left end portion in rear view).

  The attachment plate 415 of the heel base 414 is provided with an insertion port 415a having a vertically long and substantially rectangular shape at the upper and lower portions thereof. When the front frame 14 is closed, the front end portion of the front frame flange portion 14a enters the insertion port 415a.

  A plate-like sliding rod 417 formed vertically along the supporting plate 416 is slidably arranged in the vertical direction inside the supporting plate 416 of the rod base 414. In addition, a hook member (an inner frame hook member) 411 that is slidably supported by the support plate 416 while being always pulled downward by a coil spring (not shown) is disposed at two upper and lower portions of the flange base 414. Yes. The inner frame hook member 411 is formed in a hook shape with the tip portion protruding downward, and is hooked on the metal fitting 23 of the outer frame 12 to lock the inner frame 13. The inner frame collar member 411 engages with the sliding collar 417 and slides upward only when the sliding collar 417 moves upward from the neutral position. The sliding rod 417 is urged downward by a reaction force having substantially the same magnitude as the pulling force of the coil spring that urges the inner frame collar member 411.

  The upper and lower two inner frame collar members 411 are independently movable upward. When the inner frame collar member 411 is moved and unlocked with a wire or the like, both inner frames are removed. The scissor member 411 must be moved upward. Even if only one of them is moved upward, the other inner frame flange member 411 remains hooked on the receiving bracket 23 of the outer frame 12. For this reason, an unauthorized unlocking operation becomes difficult and crime prevention is improved. Further, the inner frame collar member 411 moves upward as the sliding collar 417 slides upward. The sliding rod 417 slides upward in conjunction with the clockwise operation with the dedicated key with respect to the cylinder lock 420, and the locked state of the inner frame 13 can be released by operating the dedicated key. .

  Further, at two upper and lower portions of the flange base 414, a flange member (front frame flange member) 412 supported slidably by the mounting plate 415 and the support plate 416 while being always pulled upward by a coil spring (not shown). It is arranged. The front frame flange member 412 is formed by bending a metal plate into a U-shaped cross section, and a vertically long rectangular locking port 412a is formed on the surface on the mounting plate 415 side. Further, the front frame flange member 412 has the locking port 412a overlapping the insertion port 415a formed in the mounting plate 415, and the lower end of the locking port 412a is positioned above the insertion port 415a in the neutral state. Has been placed.

  When the front frame 14 is closed, the front frame flange portion 14a enters the insertion port 415a and also enters the locking port 412a. The lower end of the locking port 412a is disposed at a position where it comes into contact with the protruding portion at the front end of the front frame flange portion 14a, and the front frame flange member 412 is pushed down by the front frame flange portion 14a and slides downward. When the protruding portion at the front end of the front frame flange portion 14a completely enters the locking port 412a, the front frame flange member 412 rises and returns to the original position by the pulling force of the coil spring, and is caught by the front frame flange portion 14a. The front frame 14 is locked so as not to be opened. Further, the front frame collar member 412 moves downward as the sliding collar 417 slides downward. The sliding rod 417 slides downward in conjunction with the counterclockwise operation with the dedicated key with respect to the cylinder lock 420, and, like the inner frame 13, the front frame 13 is locked by operating the dedicated key. Is released.

  The interlocking mechanism between the cylinder lock 420 and the sliding rod 417 will be described. As shown in FIG. 40, the lock shaft of the cylinder lock 420 has two protrusions that enter the notch of the sliding rod 417 by the rotation operation. A cam plate 420a is attached. When the dedicated key is inserted clockwise into the key hole 421 of the cylinder lock 420 and is rotated clockwise (clockwise in FIG. 38), the lower projection of the cam plate 420a enters the notch of the sliding rod 417. The sliding rod 417 is pushed upward. On the other hand, when the dedicated key is rotated counterclockwise (counterclockwise direction in FIG. 38) while being inserted into the key hole of the cylinder lock 420, the upper protrusion of the cam plate 420a enters the notch of the sliding rod 417. Then push down the sliding rod 417 downward. In this way, by sliding the single sliding rod 417 up and down freely by rotating the dedicated key, the inner frame collar member 411 and the front frame collar member 412 interlocked with the sliding rod 417 are moved. The locked state with respect to the inner frame 13 and the front frame 14 locked for each of the flange members 411 and 412 can be released by operating. Therefore, compared with the case where a plurality of sliding rods are respectively configured to be interlocked with the lock shaft of the cylinder lock, the component configuration is simplified, and the manufacturing cost can be reduced.

  A heel member (lower plate heel member) 413 that is slidably supported by the support plate 416 while being always pulled upward by a coil spring (not shown) is disposed below the heel base 414. The lower plate cage member 413 is for engaging the lower plate engaging portion 15a (see FIG. 21) provided in the lower plate unit 15 to lock the lower plate unit 15, and is located in the center along the vertical direction. The upper and lower two flanges 413a that protrude to the front side from the upper part and the lower part and further protrude from the front end part are hooked on the lower dish engaging part 15a to restrict the opening of the lower dish unit 15.

  At the upper end portion of the lower plate ridge member 413, an operation portion 413b formed so as to protrude to the front side is provided, and the lower plate ridge member 413 can be pushed downward with a fingertip or the like. ing. The operation unit 413b of the lower plate unit 15 is always disposed at a position covered by the front frame 14, and can be exposed and operated only when the front frame 14 is opened.

  When opening the lower tray unit 13 in the closed state, first, the front frame 14 is opened so that the operation portion 413b of the lower tray unit 15 can be operated. After that, when the operation unit 413b is pressed against the urging force of the coil spring and the lower plate cage member 413 is moved downward, the lower plate engagement unit 15a provided on the lower plate unit 15 side and the lower plate cage member The engagement state of the 413 with the flange portion 413a is released, and the unlocking state can be achieved by simply pulling the lower plate unit 15 forward.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. FIG. 41 is a block diagram showing an electrical configuration of the pachinko machine 10. The main controller 561 is equipped with an MPU 701 as a one-chip microcomputer that is an arithmetic unit. The MPU 701 includes a ROM 702 that stores various control programs executed by the MPU 701 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 702 is executed. A certain RAM 703 and other various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The ROM 702 has a first variation in which a variation pattern (variation time) of the first symbol (special symbol), a variation pattern command corresponding to the variation pattern, and a value of a first variation type counter CS1 (FIG. 45) described later are associated. A pattern table 702a and a second variation pattern table 702b in which a variation pattern (variation time) of the second symbol (ordinary symbol) and a variation pattern command corresponding to the variation pattern are associated with each other are stored.

  Here, the first variation pattern table 702a and the second variation pattern table 702b will be described with reference to FIG. FIG. 42A is a diagram schematically illustrating the configuration of the first variation pattern table 702a, and FIG. 42B is a diagram schematically illustrating the configuration of the second variation pattern table 702b.

  The first variation pattern table 702a is a table that stores a variation pattern of variation display of the first symbol that is variably displayed on the first symbol display device 81, and a game ball has entered the start winning opening 331,332. In this case, the variation pattern of the first symbol that is variably displayed on the first symbol display device 81 is determined with reference to the first variation pattern table 702a 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 that displays a display result that is not accompanied by reach display, and “Fluctuation fluctuation 1 (shortening)” and “Lose fluctuation” are set for two types of fluctuation time from the start to the end of fluctuation. 2 (normal) ”. “Loss variation 1” is a loss variation performed with a variation time of 5 seconds. After the left middle right symbol sequence starts to vary, the variation of the left symbol sequence is stopped 3 seconds later, and 1 second later (4 seconds after the start of fluctuation) Stop the fluctuation of the right symbol sequence, and after 1 second (5 seconds after the start of variation), stop the fluctuation of the middle symbol sequence and display the display result of the fluctuation display. It becomes. 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 variation display, even if the variation pattern is the same, the display control device 505 controls the variation display for each variation display according to the previous variation display display result (stop symbol) and the stop symbol after variation. The symbols are scrolled and displayed on the first symbol display device 81.

  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. The display result of out of alignment with no reach display is displayed. One of the “loss variation 2” and the “loss variation 1” is selectively selected according to the number of variation displays in standby. Specifically, “Loss fluctuation 1” with a short fluctuation time (5 seconds) is selected only when there are two or more fluctuation displays (the number of held balls) in standby at the beginning of the fluctuation. In the case where the variation display of the first symbol in the middle is “1” or less, “loss variation 2” is selected.

  “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, In this pattern, the fluctuation is stopped after the fluctuation speed is decelerated stepwise in one or two stages.

  “Super Reach 1” to “Super Reach 16” (hereinafter abbreviated as “Super Reach” where appropriate) has a longer design time than normal reach, and character designs such as “fish school” and “bubble” are displayed on the first symbol display device 81. This is a so-called super reach pattern to be displayed. 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. In other words, the variation time required for one variation display of the first symbol is set to a maximum of 40 seconds by “super reach 16”. During the scrolling of the first symbol, a specific character symbol (for example, a school of fish or bubbles) set for each pattern or a background display (for example, a blue background is usually changed to a rainbow color) is displayed. Accompany the display. After the characters and symbols that make up this super reach appear, the player changes to jackpot at a high ratio, and the player is strong against the occurrence of jackpots by executing the change display of the super reach where the characters and symbols appear. You will have a sense of expectation.

  The first variation pattern table 702a used for selecting each variation pattern described above includes 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, and a jackpot. It is composed of a loss reach table for determining a variation pattern of variation display that is not generated. 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 first variation type counter CS1 is divided with respect to the variation pattern with reach display. Specifically, as shown in FIG. 42A, the value of the first variation type counter CS1 updated within the range of “0 to 255” is “0 to 31”, “ The “super reach” is divided into “32 to 255”, and the fluctuation patterns of “normal reach” and “super reach” are divided into a ratio of 1: 7. In the lose reach table, the value of the first variation type counter CS1 is divided into “0 to 223” for “normal reach” and “224 to 255” for “super reach”. The variation pattern of “super 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 if you win a jackpot lottery or a lottery lottery, so if a variation pattern with reach display is selected, if you win a jackpot lottery or a lottery lottery Limited. When a big win lottery is won, a reach display is always accompanied, and the player can be expected to generate a big win by the appearance of the reach display. On the other hand, a variable display without a reach display is selected only when the jackpot lottery is not won, so a jackpot cannot occur without a reach display, and the player has a sense of expectation for the jackpot I can't. In addition, you may provide the fluctuation pattern which generates a jackpot with the fluctuation pattern which does not accompany reach display. For example, there may be provided a variation pattern 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.

  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, a 1-byte value indicating 34 fluctuation patterns from “01h” to “22h” is set for each fluctuation pattern, and these 34 values are the values of the first fluctuation type counter CS1. Are stored in each table corresponding to At the start of variation, a value indicating the variation pattern in each table is acquired based on the value of the first variation type counter CS1, and is set as the lower byte of the variation pattern command of the first symbol for designating the variation pattern. Each table is assigned the value of the first variation type counter CS1 for each 1-byte value indicating each variation pattern in “normal reach” and “super reach”. The values of the first variation type counter CS1 are collectively shown for each reach type.

  Here, a control command transmitted from the main control device 561 to the display control device 505 for controlling the variable display of the first symbol will be described. The control command for the first symbol variation display is composed of a variation pattern command, a stop symbol command, and a 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. For example, the upper byte of the first symbol variation pattern command is “C0h”, the upper byte of the first symbol stop symbol command is “C1h”, the upper byte of the first symbol confirmation command is “C2h”, and the second symbol The upper byte of the fluctuation pattern command is “D0h”, and the upper byte of the confirmation command of the second symbol is “D2h”. In the display control device 505, the type of each control command can be determined by checking the upper byte. At the start of variation of the first symbol, the main controller 561 displays a variation pattern command for designating a series of variation patterns from the start to the end of variation display and a stop symbol command indicating the type of the first symbol to be stopped. The data is transmitted to the control device 505. In addition, when the first symbol variation is stopped, a confirmation command is transmitted from the main control device 561 to the display control device 505, and the left middle right symbol of the first symbol display device 81 is confirmed as the display result of the first symbol variation display. Stop. After the confirmation command is transmitted to the display control device 505, if there is data for the variable display of the first symbol in standby, the display pattern control device 505 displays the variation pattern command and the stop symbol command of the first symbol in accordance with the data. Will be sent again.

  Note that the value of the first variation type counter CS1 does not necessarily have to be divided into the ratios set in the above-described variation pattern table 702a, and may be divided into other ratios. The variation pattern is not necessarily determined by the selection method described above, and various known techniques can be used. Furthermore, the types of variation patterns are not limited to the types described above, and may be set as fewer patterns or more patterns than those described above.

  The second variation pattern table 702b shown in FIG. 42 (b) is a table that stores a variation pattern of variation display of the second symbol performed on the display unit 83 (see FIG. 3) of the second symbol display device 81. When the game ball passes through the second entrance 67 (see FIG. 3), the second symbol display is made with reference to the second variation pattern table 702b and the gaming state such as a probability variation state in which a big hit is likely to occur. The variation pattern of the second symbol executed by the unit 83 is determined. In the pachinko machine 10 of the present embodiment, two types of variation patterns are set as the variation patterns of the second symbol. First, each variation pattern will be described.

  The “normal variation pattern” is a pattern that is set in the normal gaming state, that is, the gaming state that is not the short-time gaming state regardless of whether or not the second pattern is correct, and the variation time required from the start of the variation to the stop is set to 30 seconds. Has been. When this “normal variation pattern” is selected as the variation pattern, the symbols “◯” and “x” on the second symbol display portion 83 are alternately lit to start variation display, and 30 seconds after the start. While any of the symbols is lit, the variation display is stopped and the display result of the variation display of the second symbol appears.

  The “shortened variation pattern” is a variation pattern that is executed regardless of whether or not the second symbol is correct, and is a pattern for generating a short game state when the variation time of the second symbol is set short. The variation time required from the start of the variation to the stop is set to 5 seconds, and the variation time is significantly shortened compared to the normal gaming state. When this “shortening variation pattern” is selected as the variation pattern, “○” and “×” symbols on the second symbol display portion 83 are alternately lit to start variation display, and 5 seconds after the start. While any of the symbols is lit, the variation display is stopped and the display result of the variation display of the second symbol appears. In the pachinko machine 10, the short-time gaming state is set in the probability variation state until the variation display of the first symbol is executed 100 times after the jackpot ends. Note that it is not always necessary to set the short-time gaming state in the gaming state described above, and it may be until the first symbol variation display is executed a certain number of times after the jackpot in the probability variation state and the probability variation state, or after the jackpot It is possible to make various settings such as performing a lottery to determine whether or not to end the short-time gaming state every time the change display of one symbol is executed, and setting the short-time gaming state until winning the lottery.

  In the second variation pattern table 702b, four types of variation patterns “01h, 11h, 02h, 12h” are set as lower bytes of the variation pattern command 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 the lower byte of the second variation pattern command for designating the variation pattern. The upper 4 bits in the lower byte of each variation pattern command are values indicating the type of the second symbol to be stopped and displayed on the second symbol display unit 83. If so, the symbol “x” is stopped. The lower 4 bits in the lower byte of each fluctuation pattern command are values corresponding to the fluctuation time. If “1h”, a fluctuation time of 30 seconds is set, and if “2h”, a fluctuation time of 5 seconds is set.

  Here, a control command transmitted from the main control device 561 to the display control device 505 for controlling the variation display of the second symbol will be described. The control command for the variation display of the second symbol is composed of a variation pattern command and a confirmation command. At the start of variation of the second symbol, a variation pattern command is transmitted to the display control device 505. In addition, when the variation of the second symbol is stopped, a confirmation command is transmitted to the display control device 505, and either “O” or “X” of the display portion 42b of the second symbol is displayed as the display result of the variation display of the second symbol. The symbol is fixed and stopped. After the confirmation command is transmitted to the display control device 505, if there is data for variation display of the second symbol that is on standby, the variation pattern command is transmitted again to the display control device 505 in accordance with the data.

  Returning to FIG. The RAM 703 of the MPU 701 of the main control device 561 is configured to be able to hold (backup) data by being supplied with a backup voltage from the power supply device 612 even after the power of the pachinko machine 10 is shut off. The RAM 703 is provided with a memory, an area, a counter, and the like for temporarily storing various data and the like, and includes a backup area 703a, a big hit flag 703b, a second hit flag 703c, and a first variation time. A counter HD1, a second variation time counter HD2, a first retained ball number counter N, a second retained ball number counter M, a time-recessed number counter JN, a round remaining number counter RD, a start port opening counter SC, Various counters shown in FIG. 45 are provided.

  The backup area 703a stores values such as a stack pointer, each register, and I / O when the power is shut down (including when a power failure occurs, the same applies hereinafter) when the power is shut off due to 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 the power-off based on the information in the backup area 703a. Writing to the backup area 703a is executed when the power is shut off by the NMI interrupt process (see FIG. 56), and restoration of each value written to the backup area 703a is executed in the main process (see FIG. 46) when the power is turned on. . Note that the power failure signal SG1 from the power failure monitoring circuit 742 is input to the NMI terminal (non-maskable interrupt terminal) of the MPU 701 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 big hit flag 703b is a flag that is turned on when a big win is won by lottery based on the game balls entering the start winning ports 331 and 332. While the jackpot flag 703b is on, even if there is a variation display of the first symbol on standby, the start of the variation display is awaited, and the main control is to operate the variable prize winning device 65 to open and close the big prize opening 65a. This is performed by the control device 561. It is not always necessary to wait for the start of fluctuation of the first symbol that is waiting while the jackpot flag 703b is on, and the first symbol is displayed while the jackpot flag 703b is on. You may do it.

  The second winning flag 703c is a flag that is turned on when a lottery based on the passing of a game ball at the second entrance 67 is won. While the second winning flag is on, even if there is a variation display of the second symbol waiting, the variation display start is awaited, and the opening / closing control of the lower start winning opening 332 is performed by operating the blade 333. This is performed by the main controller 561.

  The first variation time counter HD1 is a counter for measuring the variation time of the first symbol. The main controller 561 updates the first variation time counter HD1 when transmitting a variation pattern command to the display controller 505, and measures the timing at which the display controller 505 stops and displays the first symbol. Thereby, even if a command is unilaterally transmitted from the main control device 561 to the display control device 505, it is possible to measure the fluctuation start time and the fluctuation stop time of the first symbol. The second variation time counter HD2 is a counter for measuring the variation time of the second symbol, and times the timing at which the display controller 505 stops and displays the second symbol.

  The first reserved ball number counter N is a counter that stores a value corresponding to the number of times of waiting for the variable display of the first symbol (the number of held balls) as number information. The value of the first reserved ball number counter N is “1” when a game ball enters the start winning opening 331, 332 and one of the start opening switches 524a, 524b is turned on (start winning). "1" is added, while "1" is subtracted every time the value of the reserved ball storage area, which will be described later, is shifted and the variable display of the first symbol on standby is started.

  The second reserved ball number counter M is a counter that stores a value corresponding to the number of times of waiting for the variable display of the second symbol (the number of held balls) as the number information. The value of the second reserved ball number counter N is “1” in accordance with the case where a game ball enters the second entrance 67 and the second entrance switch 525 is turned on (passing through the gate). On the other hand, the value of the reserved ball storage area, which will be described later, is shifted, and “1” is decremented each time the variable display of the second symbol on standby is started.

  The time reduction counter JN is a counter for measuring the period for generating the time reduction game by shortening the fluctuation time of the variation display of the second symbol, and a value of “100” is set with the occurrence of the jackpot, and thereafter Every time the first symbol variation display is started, “1” is subtracted and updated. At this time, the fluctuation display of the second symbol that is started when the value of the short-time counter JN is “1” or more is set to “5 seconds” as the fluctuation time, and the display result is displayed promptly after the fluctuation starts. At that time, the lower start winning opening 332 is opened. In the pachinko machine 10 of the present embodiment, the lottery conditions based on the passage of the game ball at the second entrance 67 are not different during the time-saving game and during the time-saving game. For this reason, during the short-time game, the lower start winning opening 332 is frequently held for the time interval until the lottery result is displayed, and the lower starting winning opening 332 is frequently performed. Is opened, and it is easy for a game ball to enter the lower start winning opening 332.

  In addition, when the symbol “O” is stopped and displayed during the normal game (other than the time-saving game) where the value of the time-count counter JN is “0”, the lower start winning opening 332 is opened for 0.4 seconds. On the other hand, when the symbol “◯” is stopped and displayed during the time-saving game where the value of the time-count counter JN is “1” or more, the lower start winning opening 332 is opened for 4 seconds. For this reason, almost no game ball enters the lower start winning opening 332 during the normal game, and a large amount of game balls enter the lower start winning opening 332 during the short-time game. The opening time of the lower start winning opening 332 during the short-time game is not necessarily set as described above. It is preferable to set a time during which approximately the same number of award balls are paid out and the player's balls do not increase or decrease. In addition, during the short-time game, the lower start winning opening 332 is opened more times, and the lower start winning opening 332 is opened twice or three times or more for one win. The game ball may be easily entered into the lower start winning opening 332.

  The remaining round counter RD is a counter that stores the remaining number of times (number of rounds) that the big winning opening 65a is opened after the big win. When the big win lottery is won, “16” that is the maximum number of rounds that can be continued is written in the remaining round counter RD, and the number of rounds is subtracted by “1” every time one round passes. When the value of the remaining round counter RD becomes “0”, the special game state based on the jackpot is ended, and an ending screen or the like is displayed on the first symbol display device 81 at a predetermined time after the jackpot game ends, and the special game state is displayed. End.

  The start port opening counter SC is a counter for measuring the opening / closing timing of the start port opening solenoid for opening and closing the lower start winning port 332. When the lottery based on the passing of the game ball of the second entrance 67 is won and the second winning flag 703c is turned on, the start opening solenoid is turned on and the lower start winning opening 332 is opened. At this opening time, the value of the hourly counter JN is confirmed. If the value is “1” or more and the time-short game is being played, “1000” is set so that the start port opening counter SC becomes “0” after 4 seconds. A value is written. If the value of the time-count counter JN is “0” at the opening timing of the lower start winning opening 332, the value “100” is set so that the start opening counter SC becomes “0” after 0.4 seconds. Written. By writing different values in the start opening counter SC according to whether or not a short-time game is being played, the lower start winning opening 332 is opened at different open times during the short-time game and during the normal game. be able to.

  An input / output port 705 is connected to the MPU 701 of the main controller 561 via a bus line 704 including an address bus and a data bus.

The RAM 713 is provided with a backup area 713a in addition to a memory and an area for temporarily storing various data.

  The payout launch control device 611 controls the launch of the ball launch unit 90 (the launch solenoid 92 and the electromagnet 104) in accordance with the operation of the operation handle 310 by the player. The launch solenoid 92 and the electromagnet 104 have predetermined conditions. Driving is allowed when it is in place. Specifically, it corresponds to the amount of rotation of the operation handle 310 on the condition that the touch sensor detects that the player is touching the operation handle 310 and the firing stop switch for stopping the firing is not operated. Then, the launch solenoid 92 is excited, and the game ball is launched with a strength corresponding to the operation amount of the operation handle 310.

  The backup area 713a is an area for storing stack pointers, registers, I / O values, etc. when the power is turned off when the power is cut off due to a power failure or the like. Based on the information in the backup area 713a, the state of the pachinko machine 10 is restored to the state before the power is shut off. Writing to the backup area 713a is executed when the power is shut off by the NMI interrupt process, and restoration of each value written to the backup area 713a is executed in the main process when the power is turned on. As with the MPU 701 of the main controller 561, the power failure signal SG1 is also input to the NMI terminal of the MPU 711 from the power failure monitoring circuit 742 when the power is interrupted due to the occurrence of a power failure or the like. When input to the MPU 711, an NMI interrupt process as a power failure process is immediately executed.

  An input / output port 715 is connected to the MPU 711 of the payout / release control device 611 via a bus line 714 composed of an address bus and a data bus. A RAM erase switch circuit 743, a main controller 561, a payout motor 658a, a firing solenoid 92, an electromagnet 104, and the like are connected to the input / output port 715, respectively.

  The display control device 505 displays a variation display of the second symbol (ordinary symbol) on the second symbol display device (LED) 82 and a variation display of the first symbol (special symbol) on the first symbol display device (LCD) 81. It is something to control. The display control device 505 includes an MPU 721, a ROM (program ROM) 722, a work RAM 723, a video RAM 724, a character ROM 725, an image controller 726, an input port 727, two output ports 728 and 729, and a bus line. 730 and 731. The input side of the input port 727 is connected to the output side of the main controller 561, and the output side of the input port 727 is connected to the MPU 721, ROM 722, work RAM 723, image controller 726, and output port via the bus line 729. 728 is connected. A second symbol display device 82 and an audio lamp control device 562 are connected to the output side of the output port 728. Further, an output port 729 is connected to the image controller 726 via a bus line 731, and the first symbol display device 81 is connected to the output side of the output port 729.

  The MPU 721 of the display control device 505 controls the display contents of the first symbol display device 81 and the second symbol display device 82 based on the symbol display command transmitted from the main control device 561. The ROM 722 is a memory for storing various control programs and fixed value data executed by the MPU 721, and the work RAM 723 is for temporarily storing work data and flags used when the MPU 721 executes various programs. Memory.

  The video RAM 724 is a memory for storing display data displayed on the first symbol display device 81, and the display content of the first symbol display device 81 is changed by rewriting the contents of the video RAM 724. The character ROM 725 is a memory for storing character data such as symbols displayed on the first symbol display device 81. The image controller 726 adjusts the timings of the MPU 721, the video RAM 724, and the output port 729 to intervene in reading and writing data, and reads display data stored in the video RAM 724 from the character ROM 725 at a predetermined timing. It is displayed on the symbol display device 81.

  The power supply device 612 includes a power supply unit 741 for supplying power to each part of the pachinko machine 10, a power failure monitoring circuit 742 for monitoring power interruption due to a power failure and the like, and a RAM erase switch circuit 743 having a RAM erase switch 623. ing. The power supply unit 741 supplies necessary operating voltages to the main control device 561, the payout / release control device 611, and the like through a power supply path (not shown). As its outline, the power supply unit 741 takes in an AC 24 volt voltage supplied from the outside, 12 volt voltage for driving various switches, solenoids, motors, etc., 5 volt voltage for logic, RAM A backup voltage or the like for backup is generated, and the 12 volt voltage, the 5 volt voltage, and the backup voltage are supplied to the main controller 561, the payout control device 611, and the like.

  The power failure monitoring circuit 742 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the MPU 701 of the main control device 561 and the MPU 711 of the payout launch control device 611 when the power is shut down due to the occurrence of a power failure or the like. The power failure monitoring circuit 742 monitors the voltage of DC stable 24 volts, which is the maximum voltage output from the power supply unit 741, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. Power failure signal SG1 is output to main controller 561 and payout launch controller 611. Based on the output of the power failure signal SG1, the main controller 561 and the payout launch controller 611 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 741 outputs a voltage of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the voltage of 24 VDC is less than 22 volts. Is maintained at a normal value. Therefore, main controller 561 and payout launch controller 611 can execute and complete the NMI interrupt process normally.

  The RAM erase switch circuit 743 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main control device 561 and the payout / release control device 611 when the RAM erase switch 623 is pressed. When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main controller 561 and the payout launch controller 611 clear the data in the respective backup areas 703a and 713a.

  Here, with reference to FIG. 43 and FIG. 44, the 1st symbol displayed on the 1st symbol display apparatus 81 and the display content of the 1st symbol display apparatus 81 are demonstrated. FIG. 43 is a diagram individually showing the first symbol, FIG. 44 is a diagram for explaining the display screen of the first symbol display device 81, and FIG. FIG. 44B is a diagram schematically showing an actual display screen.

  The first symbol is composed of ten kinds of main symbols with numbers from “0” to “9” and one kind of sub-pattern of petal shape formed smaller than the main symbols. As shown in FIGS. 43 (a) to 43 (i), each main symbol is configured by attaching numbers “0” to “9” on a rear symbol made of a wooden box, of which an odd number ( In the main symbols with 1, 3, 5, 7, 9), large numbers are added almost to the front of the wooden box. On the other hand, the main symbols with even numbers (0, 2, 4, 6, 8) are attached to the front of the wooden box almost fully, and attached symbols imitating characters such as furoshiki and helmets, An even number on the lower right side of the attached symbol is small in green and added so as to be displayed on the front side of the attached symbol.

  Moreover, although mentioned later for details, in the pachinko machine 10 of this embodiment, it is comprised so that a jackpot may generate | occur | produce when the same main symbol is prepared. In this case, the main symbol to which the odd number is added corresponds to a “high probability symbol”, and when the high probability symbols all come together and a big win, the special game state is entered and the special winning opening 65a is released a predetermined number of times over a predetermined time. After that, it shifts to a high probability state. On the other hand, the main symbol to which an even number is added corresponds to a “low probability symbol”, and when the low probability symbols all come together to win a big game, it shifts to a special gaming state, but in such a case, it does not shift to a high probability state. . Here, the high probability state is a state in which the combination of the first symbol becomes a jackpot as a combination of the probability variation symbols determined in advance, and the subsequent jackpot probability is increased as added value, that is, a so-called probability variation (probability change). Say. In addition, the normal state (low probability state) means a time when the probability of hitting is not probable, and a state where the jackpot probability is a normal state, that is, a state where the probability of jackpot is lower than that during the probability change.

  Next, the display screen of the first symbol display device 81 will be described. As shown in FIG. 44 (a), the display screen of the first symbol display device 81 is roughly divided into two vertically, and the lower 2/3 is the main display area Dm in which the first symbol is variably displayed. The upper third is a sub display area Ds for displaying a notice effect and a character.

  In the main display area Dm, three symbol rows Z1, Z2, and Z3 of left, middle, and right are displayed. In each of the symbol rows Z1 to Z3, the above-described first symbols are displayed in a prescribed order. That is, in each of the symbol rows Z1 to Z3, the main symbols are arranged in ascending or descending numerical order, and one sub symbol is arranged between the main symbols. For this reason, a total of 20 first symbols of 10 main symbols and 10 sub-symbols are set in each symbol row, and each symbol row Z1 to Z3 is scrolled from top to bottom with periodicity. The display is changed. In particular, the main symbol numbers are arranged in descending order in the left symbol row Z1, and the main symbol numbers are arranged in ascending order in the middle symbol row Z2 and the right symbol row Z3.

  In the main display area Dm, the first symbols are displayed in the upper, middle, and lower three rows for each symbol row Z1 to Z3. Accordingly, the first symbol display device 81 displays a total of nine first symbols of 3 rows × 3 columns. In the main display area Dm, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set. In each game, the variable display stops in the order of the left symbol row Z1 → the right symbol row Z3 → the middle symbol row Z2, and the combination of jackpot symbols on any active line at the time of the stop (in this embodiment, A jackpot moving image is displayed as a jackpot if the same combination of main symbols is arranged.

  The sub display area Ds is horizontally long above the main display area Dm, and is further equally divided into three notice areas Ds1 to Ds3 in the left-right direction. Here, the left and right notice areas Ds1, Ds3 are usually covered with a double-open opaque door that is electrically opened and closed by a solenoid, and sometimes the solenoid is excited and the door is opened to the front side. The display area is visible to the player. The center notice area Ds2 is a display area that is always visible without being covered by the door.

  On the actual display screen, as shown in FIG. 44B, a total of nine main symbols and sub-designs of the first symbol are displayed in the main display area Dm. In the sub display area Ds, the left and right doors are in a closed state, and the left and right notice areas Ds1, Ds3 are covered and the display screen cannot be visually recognized. If one or both of the left and right doors are opened during the variable display, a video is displayed in the left and right notice areas Ds1, Ds3, and it is easy for the player to make a transition to a big hit than usual. It is suggested. In the center notice area Ds2, a predetermined character (a boy with a bee in this embodiment) usually performs a predetermined action and sometimes performs a special action different from the predetermined action or another character appears. The announcement effect is performed by putting out. The display screen of the first symbol display device 81 is basically divided into upper and lower display areas Dm, Ds, but displays the first symbol, characters, etc. larger across the display areas Dm, Ds. A display effect can be performed.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 701 in the main control device 561 uses various counter information during the game to perform jackpot lottery, setting the symbol display of the first symbol display device 81, and the like. Specifically, As shown in FIG. 45, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selection of the jackpot symbol of the first symbol display device 81, and the first symbol display device 81 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1, CS2 used for variation pattern selection of the first symbol display device 81, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there. The second symbol random number counter C4 is used for the lottery of the second symbol display device 82.

  Among these, the counters C1 to C4, 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 701, 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 703. The RAM 703 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, the start winning ports 331 and 332 are provided. Each value of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 is stored in accordance with the winning timing of the game balls.

  For details of each counter, the jackpot random number counter C1 is configured so that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once every timer interruption and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the start winning opening 331,332. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the values are “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot symbol counter C2 determines the symbol at the time of the fluctuation stop of the first symbol display device 81 at the time of the jackpot, and in the present embodiment, the first symbol display device 81 has five effective lines, Since ten specific symbols (main symbols) are set, 50 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is incremented one by one within the range of 0 to 49, and after reaching the maximum value (ie 49), returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the start winning opening 331,332.

  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. Reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 81, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is periodically updated (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the start winning opening 331,332.

  Of the two variation type counters CS1 and CS2, one of the first variation type counters CS1 is incremented one by one within a range of 0 to 255, for example, and after reaching a maximum value (ie 255), returns to 0. For example, the other second variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0.

  The first variation type counter CS1 determines the reach type of the first symbol, such as so-called normal reach, super reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (this embodiment) In the form, 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 first symbol is started by the first symbol display device 81.

  The left, middle and right off symbol counters CL, CM, and CR are used to determine the stop symbol of the left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 when the big hit lottery is missed. In addition, since any one of the 20 first symbols including the main symbol and the sub symbol is displayed in each stage of each column, 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 701. 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 in the normal processing so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach of the RAM 703 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 variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier and the completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

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

  The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and it is detected that the game ball has passed either the left or right second entrance (through gate) 67. Get when it is done. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the MPU 701 in the main controller 561 will be described with reference to the flowcharts of FIGS. 46 to 56. The MPU 701 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in 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. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 55 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 701 of the main controller 561 every 2 ms, for example. In the timer interruption process, first, reading processes of various winning switches are executed (S701). That is, the state of various switches (excluding the RAM erase switch 623) connected to the main controller 561 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 (S702). 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 703.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the second symbol random number counter C4 are updated (S703). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, the reach random number counter C3, and the second symbol random number counter C4 are each incremented by 1 and their counter values are the maximum values (in this embodiment, 676, 49, 238, 250), each is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 703. After that, a start winning process (S711 to S714) based on the game balls entering the start winning holes 331 and 332 and a gate passing process (S721 to S724) based on the game balls passing through the second winning hole 67 are performed. Execute.

  In the start winning process after S711. First, it is determined from the detection information of each start port switch 524a, 524b whether or not the game ball has won a start winning port 331, 332 (start winning) (S711). If it is determined that the game ball has won the start winning opening 331, 332 (S711: Yes), based on the value of the first reserved ball number counter N, the number of the active reserved balls of the first symbol is the upper limit (this embodiment In the form, it is determined whether or not it is less than 4) (S712). If there is a winning at the start winning opening 331, 332 and the first reserved ball number counter N is less than 4 (S712: Yes), the value of the first reserved ball number counter N is incremented by 1 (S713), and 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 S703 are used as the first among the free reserved areas of the reserved ball storage area provided in the RAM 703 for displaying the first symbol variation. (S714). On the other hand, if there is no winning at the start winning opening 331, 332 (S711: No), or even if there is a winning at the starting winning opening 331, 332, the first reserved ball number counter N is 4 (S712: No), each process of S713 and S714 is skipped, and the process proceeds to S721.

  After completion of the start winning process, the gate passing process after S721 is performed. In the gate passing process. First, it is determined from the detection information of the second entrance switch 525 whether or not the game ball has passed through the second entrance 67 (passing through the gate) (S721). If it is determined that the game ball has passed through the second entrance 67 (S721: Yes), the number of the operation reservation balls of the second symbol is based on the value of the second reservation ball number counter M (the present embodiment) In the form, it is determined whether or not it is less than 4) (S722). If there is a game ball passing through the second entrance 67 and the second reserved ball number counter M is less than 4 (S722: Yes), the value of the second reserved ball number counter M is incremented by 1 (S723). Further, the value of the second symbol random number counter C4 updated in the step S703 is stored in the first area among the empty reserved areas of the reserved ball storage area provided in the RAM 703 for displaying the variation of the second symbol (S724). ). On the other hand, if there is no game ball passing through the second entrance 67 (S721: No), or even if there is a game ball passing through the second entrance 67, the second reserved ball counter M is 4. If (S722: No), each process of S723 and S724 is skipped, and the start winning process is terminated. After the start winning process is finished, the MPU 701 once ends this timer interrupt process.

  When the game ball wins the start winning opening 331, 332 (start winning), the first symbol display by the first symbol display device 81 is started accordingly, but after the start winning, There is a restriction that a predetermined time (for example, 5 seconds) must elapse before the symbol changes and the symbol stops. 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 703 together with the values of the respective counters C1 to C3. In setting the first symbol variation pattern, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed).

  FIG. 56 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 701 of the main controller 561 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption processing, the state of the main controller 561 at the time of power-off is stored in the backup area 703a of the RAM 703. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure, the power failure signal SG1 is output from the power failure monitoring circuit 742 to the NMI terminal of the MPU 701 in the main controller 561, and the MPU 701 interrupts the control being executed. NMI interrupt processing is started. The NMI interrupt processing program in FIG. 56 is stored in the ROM 702 of the main controller 561. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 741 so that the processing of the main controller 561 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 703a of the RAM 703 (S801), and the value of the stack pointer is stored in the backup area 703a (S802). Further, the occurrence information of the power shutdown is set in the backup area 703a (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 703a (S805). The RAM determination value is, for example, a checksum value at the work area address of the RAM 703. Thereafter, access to the RAM 703 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and the processing cannot be executed.

  The above NMI interruption process is also executed in the same manner in the payout / release control device 611. With this NMI interrupt process, the state of the payout / discharge control device 611 at the time of power interruption due to the occurrence of a power failure or the like changes the backup area 713a of the RAM 713. Is remembered. Similarly, power is supplied from the power supply unit 741 so that the process of the payout / discharge control device 611 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power supply 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 742 to the NMI terminal of the MPU 711 in the payout launch control device 611, and the MPU 711 interrupts the control being executed. Then, the NMI interrupt process of FIG. 56 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 46 is a flowchart showing main processing executed by the MPU 701 in the main controller 561. 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 (sound lamp control device 562, payout launch control device 611, etc.) to become operable. , Wait processing (for example, about 1 second) is executed. Next, after a payout permission command is transmitted to the payout launch control device 611 (S102), access to the RAM 703 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch 623 provided in the power supply device 612 is turned on (S104). If the RAM erase switch 623 is turned on (S104: Yes), processing is performed to clear (erase) the backup data. The process proceeds to S114. On the other hand, if the RAM erasure switch 623 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 703a of the RAM 703 (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 703a (S105: Yes), the RAM judgment value is calculated (S106), and 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 at the time of power-off, the backed up data has been destroyed. Even in such a case, the process proceeds to S114. As described above, the RAM determination value is a checksum value at a work area address of the RAM 703, 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 703 is correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in a hall, the power is turned on while pressing the RAM erase switch 623. Therefore, if the RAM erase switch 623 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 703 in the same manner. That is, in the RAM initialization process from S114, the used area of the RAM 703 is cleared to 0 (S114), and the initial value of the RAM 703 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 erase switch 623 is not turned on (S104: No), the occurrence information 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 703a of the RAM 703 (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 S208 is executed as a periodic process of a 4 ms cycle, and the counter update process of S210 and S211 is executed in the remaining time.

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout launch control device 611. Also, a stop control command, a change pattern command, a confirmation command, etc. are displayed in order to execute a change display of the first symbol by the first symbol display device 81, a change display of the second symbol by the second symbol display device 82, etc. To 505. In addition, after the start of the first symbol variation, each time normal processing is performed in the order of the variation pattern command → the left symbol row Z1 stop symbol command → the middle symbol row Z2 stop symbol command → the right symbol row Z3 stop symbol command. The commands are transmitted one by one (that is, one every 4 ms), and the confirmation command is transmitted at the end of the fluctuation time.

  Next, each value of the variation type counters CS1 and CS2 is updated (S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1 and cleared to 0 when their counter values reach the maximum value (255, 240 in this embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 703. Further, the outlier counters CL, CM, CR of the left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 are updated by the off symbol counter updating process (S203).

  Here, with reference to FIG. 48, the off symbol counter update process will be described. First, it is determined whether or not it is the update time of the out symbol counter CL of the left symbol row Z1 (S301), and if it is the update time (S301: Yes), the out symbol counter CL of the left symbol row Z1 is updated (S303). . Next, if it is not the update time of the left symbol row Z1 (S301: No), it is determined whether it is the update time of the out symbol counter CM of the middle symbol row Z2 (S302), and if it is the update time (S302: Yes). ), The outlier symbol counter CM of the middle symbol row Z2 is updated (S304). Furthermore, if it is not the update time of the middle symbol row Z2 (S302: No), it is the update time of the right symbol row Z3, so the outlier symbol counter CR of the right symbol row Z3 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 CL, CM, and CR update processing, the outlier symbol counters CL, CM, and CR of the left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 are sequentially updated one by one in one normal process. Therefore, the update times of the counter values do 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 703 (S309). If the out symbol counters CL, CM, CR are combinations other than front / rear out of reach (S308: No), the combination of out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / rear out of RAM 703 (S310). ). If the combination of the off symbol counters CL, CM, CR is not a jackpot symbol combination (S306: No) and is not a reach symbol combination (S307: No), the combination of the off symbol counters CL, CM, CR is a reach 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 703 (S311).

  After completion of the off symbol counter CL, CM, CR update process (S203), the process returns to the normal process of FIG. A first symbol variation process for performing variation display of the first symbol by the one symbol display device 81 is executed (S205). By this first symbol variation process, jackpot determination, setting of a variation pattern of the first symbol, and the like are performed. Details of the first symbol variation process will be described later with reference to FIG.

  After the end of the first symbol variation process, a jackpot process for opening or closing the big prize opening 65a of the variable prize winning device 65 is executed in the case of the big prize state (S206). That is, the big winning opening 65a is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening 65a has passed or whether a predetermined number of game balls have won the big winning opening 65a. When any of these conditions is satisfied, the special winning opening 65a is closed. At this time, the special winning opening 65a is allowed to be continuously opened on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds. Details of the jackpot process will be described later with reference to FIG.

  Next, a second symbol variation process for controlling the display content of the second symbol (for example, “◯” or “x”) by the second symbol display device 82 is executed (S207). On the condition that the game ball has passed through the second entrance (through gate) 67, the value of the second symbol random number counter C4 is acquired at the passing timing, and the lottery of the second symbol is performed based on the acquired value. Then, a command to be transmitted to the display control device 505 is determined so that the second symbol corresponding to the lottery result is displayed on the display unit 83 of the second symbol display device 82.

  After the process of S207, a start port opening / closing process (S208) for controlling the operation of the blade 333 that opens and closes the lower start winning opening 332 is executed. When the second symbol hit state is obtained in the process of S207, the start opening solenoid as an electric accessory for opening and closing the lower start winning opening 332 is operated. When the start port opening solenoid operates, the pair of blades 333 are tilted so that the upper portions of the pair of left and right blades 333 are opened to the left and right sides, and the lower start winning port 332 is opened for a predetermined time.

  Thereafter, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 ms in the present embodiment) has elapsed since the start of the previous normal process (S209). If (S209: Yes), the process proceeds to S201, and the processes after S201 described above are repeatedly executed.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal process (S209: 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 (S210, S211). First, the random number initial value counter CINI is updated (S210). 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 703. Next, the fluctuation type counters CS1 and CS2 are updated (S211). Specifically, the variation type counters CS1 and CS2 are incremented by 1 and cleared to 0 when their counter values reach the maximum value (255, 240 in the present embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 703.

  Here, since the execution time of each process of S201 to S208 changes according to the state of the game, the remaining time until the next normal process execution timing is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The variation type counters CS1 and CS2 can also be updated at random.

  Next, the first symbol variation process (S205) will be described with reference to the flowcharts of FIGS. In the first symbol variation process, first, it is determined whether or not the big hit flag 703b is on and the current big hit (that is, in the special gaming state) is present (S401). The jackpot includes a jackpot game displayed on the first symbol display device 81 in the case of a jackpot and 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. Note that the process of S401 is a process for waiting for the start of variable display of the first symbol during the jackpot and starting the variable display of the first symbol only during a period other than the jackpot game, and it is not always necessary to provide it. Alternatively, the process of S401 may be deleted so that the variable display of the first symbol is executed even during the big hit.

  If it is not a big hit in the process of S401 (S401: No), whether or not the first variation time counter HD1 is greater than “0”, that is, whether or not the first symbol display device 81 is currently displaying the variation of the first symbol. If it is determined (S402) and the first symbol variation is not being displayed (S402: No), it is determined whether or not the value of the first reserved ball number counter N is greater than 0 (S403). If the value of the first reserved ball number counter N is 0 (S403: No), this process is terminated as it is. If the value of the first reserved ball number counter N is larger than 0 (S403: Yes), the value of the first reserved ball number counter N is decremented by 1 (S404), and the data stored in the reserved ball storage area 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, and 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, a first change start process for selecting a change pattern or the like to start changing the first symbol is executed (S406). The first variation start process will be described later with reference to FIG.

  In the process of S402, when the variation of the first symbol is being displayed (S402: Yes), 1 is subtracted from the value of the first variation time counter HD1 (S411), and the first variation time counter HD1 after the subtraction is It is determined whether or not the value is 0 or more (S412). The variation time of the first symbol is determined according to the variation pattern, and a value corresponding to the length of the variation time is written to the first variation time counter HD1 when variation display of the first symbol is started. The processing of S412 is repeated until the value of the first variation time counter HD1 becomes 0 and the variation time of the variation display being executed elapses, and during the period, the execution of the processing from S413 to S418 is skipped (S412: Yes). ).

  On the other hand, if the value of the first variation time counter HD1 is 0 in the process of S412, that is, if the variation time of the first symbol has passed (S412: No), the confirmation command set for the determination of the stop symbol is set. (S413) It is determined whether or not the value of the time reduction counter JN is greater than 0 (S414). If the value of the time reduction counter JN is larger than 0 (S414: Yes), 1 is subtracted from the value of the time reduction counter JN (S415), and the process proceeds to S416. If the value of the time reduction counter JN is 0, the process proceeds to S416 without updating the value of the time reduction counter JN. The value of the hour / times counter JN is set to a value larger than 0 until the display of 100 variations after the big hit is executed by the processing of S415 and S416, and when the value exceeds 100 times, the value of the hour / times counter JN is set to 0. Can be maintained.

  In the process of S416, it is determined based on the data in the execution area whether or not the current fluctuation display is a big hit fluctuation display (S416). “16” is written in the remaining round counter RD (S417), the big hit flag 703b is turned on (S418), and the first symbol variation process (S205) is ended. By writing “0” in the hour / count counter JN by the processing of S417, the game state can be changed to a normal game other than the time / short game after the big hit is started. If it is determined that the process is not a big hit in the process of S416 (S416: No), the process of S417 and S418 is skipped and the first symbol variation process (S205) is terminated.

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

  When it is determined that the game is a big hit (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol is obtained based on a table (not shown) representing the corresponding relationship, and the symbol is set as a stop symbol command (S502). At this time, the numbers 0 to 49 of the jackpot symbol counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. Among these jackpot symbols, when a predetermined specific symbol (in this embodiment, an odd-numbered main symbol) is aligned, the process proceeds to a probabilistic state, but a symbol that is not a specific symbol (in this embodiment, an even number) If the numbers are aligned in the main symbol), the probability change state is not entered.

  Next, the variation pattern of the first symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command (S503). At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 703 are confirmed, and the reach type such as normal reach, super reach, or the like based on the first variation type counter CS1 and the first variation pattern table 702a. And other rough symbol variation modes, and the elapsed time (in other words, the middle symbol Z2 in the present embodiment) after the reach has occurred, based on the values of the variation type counters CS1 and CS2, , The number of variation symbols), etc., to determine a more detailed symbol variation mode. 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.

  In the process of S503, a value obtained by multiplying the determined variation pattern variation time by 4 ms is written to the first variation time counter HD1. The value of the first variation time counter HD1 is decremented by 1 by the processing of S411 executed every 4 ms in the normal processing, and the timing when the value of the first variation time counter HD1 becomes “0” is the variation display end timing. Become. The value written to the first variation time counter HD1 in the process of S503 is stored in the first variation pattern table 702a. In the processes of S507, S509, and S511, similarly to the process of S503, a value obtained by multiplying the determined variation time of the variation pattern by 4 ms is written to the first variation time counter HD1.

  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 reach reach 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 703 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 703 are confirmed, and the first variation type counter CS1 and the loss reach table of the first variation pattern table 702a The reach type such as normal reach, super reach, and other rough symbol variation modes are determined based on the value of the second variation type counter CS2, and the final stop symbol (the middle symbol in the present embodiment) is determined after the reach occurs. A more detailed symbol variation mode such as the elapsed time until the stop (in other words, the number of variation symbols) is determined.

  When a reach other than front / rear out is generated (S505: No), each value of left, middle and right out of symbol counters CL, CM, CR stored in the reach symbol buffer other than front / rear out of RAM 703 is set as a stop symbol command. (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 variation type counters CS1, CS2, etc. stored in the counter buffer of the RAM 703, 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 703 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 703, as in the process of S503. As described above, when the setting of the stop symbol command and the fluctuation pattern command is completed in any of the big hit, the reach occurrence, and the reach non-occurrence, this processing is ended.

  Next, the jackpot process (S206) will be described with reference to FIG. The big win process (S206) controls the operation of the big prize opening opening solenoid when the big prize is won by the lottery based on the winning to the start winning holes 331 and 332, and the big prize opening 65a of the variable winning device 65 is controlled by a predetermined number of times. Is a process of releasing The jackpot process (S206) is a process for starting a short-time game at the timing when the last (sixteenth) jackpot 65a is opened, just before the end of the jackpot game.

  In the jackpot process (S206), first, it is determined whether or not the jackpot flag 703b is on and the jackpot is being hit (S541). If it is determined that the jackpot flag 703b is off and the jackpot is not hit (S541: No), the subsequent processing is skipped and the present processing is terminated, and the processing is returned to the normal processing of FIG.

  If it is determined in the process of S541 that the big hit flag 703b is on (S541: Yes), the big win port 65a needs to be opened and closed because it is a big win. For this reason, the big prize opening 65a is closed (S542: Yes), and when the big prize opening 65a is opened (S543: Yes), the big prize opening opening solenoid provided in the variable prize winning device 65 is turned on. The special winning opening 65a is opened (S544). The opening time of the big prize opening 65a is that the value of the remaining round counter RD is “1” or more, and whether a fixed time has passed after the variable display is confirmed and stopped in the big hit symbol, or the previous big prize opening This is the time when any one of the conditions for the fixed time has elapsed since the closing of 65a. On the other hand, when the big prize opening 65a is open (S542: No), or even when the big prize opening 65a is closed, it is not the opening time of the big prize opening 65a (S543: No), the process of S544 is performed. The process skips to S545.

  In the process of S545, it is determined whether or not it is the closing time of the special winning opening 65a (S545). The closing time of the big prize opening is a time when either a certain time has elapsed since the opening of the big prize opening or 10 balls have been won in the big prize opening. If it is the closing timing of the big prize opening 65a (S545: Yes), the big prize opening opening solenoid is turned off (S546), and it is determined whether or not the game ball has won the V zone while the big prize opening 65a is opened. (S547). If the winning of the game ball to the V zone is confirmed in the processing of S547 (S547: Yes), the continuation right is established, and “1” is subtracted from the remaining round counter RD (S548), and the remaining round after the subtraction It is determined whether or not the value of the number counter RD is “1” (S549). If the value of the remaining round counter RD is “1” (S549: Yes), “100” is written in the time-count counter JN. The round remaining number counter RD becomes “1” at the timing when the grand prize winning opening 65a that is opened up to 16 times is opened 15 times and the 16th time is opened. The variation time of the second symbol variation display started after “100” is written is as short as 5 seconds, and a transition is made to a short-time game.

  If the value of the remaining round counter RD is not “1” in the process of S549 (S549: No), the jackpot process (S206) is terminated. Further, when it is confirmed in the process of S547 that there is no winning of the V zone (S547), the continuation right is not established, and “0” is written in the round remaining number counter RD (S551), and then the number of times is shortened. “100” is written in the counter JN, and a transition to the short-time game is made.

  If it is not the closing time of the big winning opening in the process of S545 (S545: No), it is determined whether the remaining round counter RD is larger than “0” (S552), and if it is larger than “0” (S552: Yes), the big hit process (S206) is ended. If the remaining round counter RD is “0” in the process of S552 (S552: No), it is a period in which the closing of the last big winning opening 65a is finished and the jackpot end effect is executed, and the execution of the end effect is performed. It is determined whether or not time has passed (S553). If the execution time of the end effect has not elapsed (S553: No), the jackpot process (S206) is ended. If the execution time of the end effect has elapsed (S553: Yes), the jackpot flag 703b is turned off. From (S554), the jackpot processing (S206) is terminated. When the jackpot flag 703b is turned off, the first symbol variation display is started based on winning at the start winning ports 331 and 332 before and during the jackpot.

  In this way, in the jackpot process (S206) of the pachinko machine 10, "100" is written to the hour / count counter JN at the timing when the big winning opening 65a is opened 15 times by the processes of S549 and S550 and the 16th release is performed. Then, the variation display of the second symbol that is started thereafter is assumed to be the variation display during the short time. In addition, the processing of S552 to S554 turns off the jackpot flag 703b after the execution time of a certain end effect has elapsed after the big winning opening 65a is finally closed as the end of the special gaming state based on one jackpot. Then, the variable display of the first symbol is started. For this reason, the selection ratio of the variation pattern of the second symbol is switched from the state of selecting the normal variation pattern to the state of selecting the shortened variation pattern before the final winning opening 65a is finally closed, and during the execution period of the end effect The variation display of the second symbol starting at the same time is a variation display by a shortened variation pattern. Therefore, since the display result of the dynamic display by the second symbol started during the execution period of the end effect is displayed in a short time, the display result of the variable display by the second symbol in a short time from the end time of the special gaming state. Is easily displayed and the open state is easily formed after the special gaming state. Therefore, when a short-time game is performed immediately after the end of the special game state, it is possible to provide the player with a game in which a decrease in game balls is suppressed by the short-time game. In the pachinko machine 10, the selection of the normal variation pattern and the shortened variation pattern is fixedly switched based on whether the time is short or not, but it is not always necessary to make the selection as described above. The normal variation pattern and the shortened variation pattern may be selected at another selection ratio set so that the shortened variation pattern can be easily selected. For example, a normal variation pattern and a shortened variation pattern are selected at a selection ratio of 9: 1 during a normal game, and a selection variation ratio of 2: 8 is selected during a short-time game. The variation pattern may be selected at a ratio that is determined.

  Next, the second symbol variation process (S207) will be described with reference to the flowcharts of FIGS. In the second symbol variation process, first, it is determined whether or not the second winning flag 703c is ON and the current start winning opening 332 is being opened (open state, see FIG. 5) (S561). ). As a result of the determination, if the second hit flag 703c is on (S561: Yes), this processing is terminated as it is.

  If the second hit flag 703c is off (S561: No), it is determined whether or not the second variation time counter HD2 is larger than “0”, that is, whether or not the second symbol variation is being displayed (S562). If the second symbol variation display is not in progress (S562: No), it is determined whether or not the value of the second reserved ball number counter M is greater than 0 (S563). If the value of the second reserved ball number counter M is 0 (S563: No), this process is terminated as it is. If the value of the second reserved ball number counter M is larger than 0 (S563: Yes), the value of the second reserved ball number counter M is decremented by 1 (S564), and it is stored in the reserved ball storage area for variable display of the second symbol. The stored data is shifted (S565). After the data shift process, the second fluctuation start process for starting the fluctuation of the second symbol is executed (S566). The second variation start process (S566) will be described later with reference to FIG.

  In the process of S562, when the variation of the second symbol is being displayed (S562: Yes), 1 is subtracted from the value of the second variation time counter HD2 (S567), and the second variation time counter HD2 after the subtraction is updated. It is determined whether or not the value is 0 or more (S568). The variation time of the second symbol is determined according to the variation pattern, and a value corresponding to the length of the variation time is written to the second variation time counter HD2 when the variation display of the second symbol is started. The processing of S568 is repeated until the value of the second variation time counter HD2 becomes 0 and the variation time of the variation display being executed elapses. During that period, the execution of the processing from S569 to S571 is skipped (S568: Yes). ).

  On the other hand, if the value of the second variation time counter HD2 is 0 in the processing of S568, that is, if the variation time of the second symbol has passed (S568: No), the confirmation command set for determining the stop symbol is set. (S569). Thereafter, it is determined whether or not the current fluctuation display is a win fluctuation display based on the execution area data (S570), and if it is a win (S570: Yes), the second hit flag 703c is turned on (S571). Then, the second symbol variation process (S207) is terminated. When it is determined that it is not a hit in the process of S570 (S570: No), the process of S571 is skipped and the second symbol variation process (S207) is ended.

  Next, the second variation start process will be described with reference to the flowchart of FIG. In the second variation start process (S566), first, it is determined whether or not it is a hit based on the value of the second symbol random number counter C4 stored in the execution area of the reserved ball storage area (S581). As described above, “5-153” is the winning value among the numerical values 0-250 of the second symbol random number counter C4.

  If it is determined that it is a win (S581: Yes), the upper 4 bits in the lower byte of the fluctuation pattern command are set as “0h” as the win fluctuation pattern command. If it is determined that it is not a hit (S581: No), the upper 4 bits in the lower byte of the variation pattern command are set as “1h” as an outlier variation pattern command.

  Next, it is determined whether or not the value of the time reduction counter JN is greater than “0” (S584). 1250 is written (S585), and it is set to be the timing for stopping the fluctuation of the second symbol 5 seconds after 1250 is multiplied by 4 ms. Further, a variation pattern command for a shortened variation pattern is set (S586), and the second variation start process (S566) is terminated.

  If the value of the time-count counter JN is “0” in the process of S584 (S584: No), 7500 is written in the second variation time counter HD2 in order to enter the normal game other than the time-short game (S587), 7500 Is set to be the timing of the second symbol fluctuation stop 30 seconds after multiplying by 4 ms. Further, a variation pattern command for the normal variation pattern is set (S588), and the second variation start process (S566) is terminated.

  Next, the start port opening / closing process (S208) will be described with reference to FIG. The start port opening / closing process (S208) controls the operation of the start port opening solenoid when it is won by lottery based on the passing of the game ball of the second entrance 67, This is a process of opening the start winning opening 332.

  In the start port opening / closing process (S208), first, it is determined whether or not the second winning flag 703c is on and the lottery based on the passing of the game ball of the second entrance 67 has been won (S591). If it is determined that the second hit flag 703c is off and not hit (S591: No), the subsequent processing is skipped and this processing is terminated, and the processing returns to the normal processing of FIG.

  When it is determined in the process of S591 that the second winning flag 703c is on (S591: Yes), it is necessary to open the lower start winning opening 332. Therefore, it is determined whether or not the start port opening counter SC is larger than “0” (S592). The solenoid is turned on to open the lower start winning opening 332.

  Thereafter, it is determined whether or not the value of the time-count counter JN is greater than “0” (S594). If it is “0” (S594: No), “100” is written to the start port opening counter SC (S595). The opening / closing process (S208) ends. If the value of the time reduction counter JN is larger than “0” in the process of S594 (S594: Yes), “1000” is written to the start port opening counter SC (S596), and the start port opening / closing process (S208) is terminated.

  When it is determined in the process of S592 that the start port opening counter SC is greater than “0” (S592: Yes), the value of the start port opening counter SC is decremented by “1” (S597). As described above, the start port opening / closing process (S208) is a process executed every 4 ms in the normal process. Therefore, the value of the start port opening counter SC is “1” every 4 ms by the process of S597. Subtracted. For this reason, when “100” is written in the value of the start port opening counter SC by the process of S595, the start port opening counter SC becomes “0” after 0.4 seconds after multiplying 100 by 4 ms, and S596. When “1000” is written in the value of the start port opening counter SC by the above processing, the start port opening counter SC becomes “0” after 4 seconds have elapsed by multiplying 1000 by 4 ms.

  In the process of S598, the value of the start port opening counter SC subtracted by the process of S597 is determined (S598). If the value of the start port open counter SC is larger than “0” (S598: Yes), the process of S599 and S600 is performed. The process is skipped and the start port opening / closing process (S208) is terminated. If the value of the starting port opening counter SC is “0” in the processing of S598 (S598: No), the starting port opening solenoid is turned off to close the lower starting winning port 332 (S599), and the second winning flag 703c is turned off and the start port opening / closing process (S208) is terminated. During the period when the value of the start port opening counter SC is larger than “0”, the lower start winning port 332 is opened, and when the value of the time counter JN is larger than “0”, 4 seconds during the short game. During the normal game where the value of the time-count counter JN is “0”, the lower start winning opening 332 is opened for 0.4 seconds. Thereby, during the short-time game, it becomes easy to win the game ball to the lower start winning opening 332, and the decrease of the game ball during the short-time game can be suppressed.

  Next, with reference to FIG. 57, payout and launch control executed by the MPU 711 in the payout launch control device 611 will be described. FIG. 57 is a flowchart showing a main process of the payout / discharge control device 611, and this main process is started by a reset at power-on.

  First, initial setting processing accompanying power-on is executed (S901). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Next, it waits for reception of the payout permission command transmitted from the main controller 561 (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 713 in the MPU 711. Specifically, it is determined whether or not the RAM erase switch 623 provided in the power supply device 612 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 623 is not turned on (S905: No), it is further determined whether or not the information on the occurrence of power interruption is stored in the backup area 713a of the RAM 713 (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 713a (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 713, 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 713 is correctly stored.

  In the RAM initialization process from S915, the used area of the RAM 713 is cleared to 0 (S915), and the initial value of the RAM 713 is set (S916). Thereafter, initialization of the MPU 711 peripheral device is performed (S917), an interrupt is permitted (S918), and the process proceeds to a payout launch control process described later.

  On the other hand, if the RAM erase switch 623 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 711 peripheral device is initialized (S911), and the used register is restored from the backup area 713a of the RAM 713 (S912). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S913). If the interrupt is permitted (S913: Yes), the interrupt is permitted (S914), while the interrupt is prohibited when the power is turned off. If it is in the state (S913: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, with reference to the flowchart of FIG. This payout launch control process is executed following the main process of the payout launch control device 611. In the payout launch control process, first, a command from the main controller 561 is acquired, and the total number of prize balls is stored (S1001). Next, the touch control of the operation handle and the state of the rotation amount are detected, and a firing control process for exciting the firing solenoid 92 and the electromagnet 104 as necessary is performed (S1002). Next, as a result of checking the state return switch 621, when it is determined that the state return operation starts, the state return operation is executed (S1003).

  Thereafter, the setting of the lower plate full state or the lower plate full state is executed according to the change in the state of the lower plate 301 (S1004). That is, when the lower pan 301 is detected based on the detection signal from the lower pan full switch, the lower pan full state is set when the lower pan is full. , 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 the state to be notified is determined, and if there is a state to be notified, the 7-segment LED provided in the payout launch control device 611 is notified (S1006).

  Next, a prize ball payout process is executed by each process of S1007 to S1009. That is, if the prize ball is not paid out and the total number of prize balls stored in the process of S1001 is not 0 (S1007: No, S1008: No), the prize ball control process shown in FIG. 59 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 processing 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 ball rental shown in FIG. Control processing is started. On the other hand, if the rental ball cannot be paid out (S1010: Yes) or if a rental ball payout 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 621 is checked to execute the ball removal process by driving the dispensing motor 658a on the condition that the ball removal is not disabled and the ball removal operation is not started. Subsequently, the control of vibrator 660 (vibration motor control) is executed on condition that the ball is clogged (S1014). After that, the process returns to the top of the payout launch control process, and thereafter the process described above is repeated.

  Next, the prize ball control process shown in FIG. 59 will be described. In the winning ball control process, firstly, the payout motor 658a is driven to rotate in the forward direction to pay out the winning ball (S1101). Whether the rotation of the payout motor 658a is normal is determined based on the detection result of the payout rotation sensor (S1102). If not normal (S1102: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a. The stop process is executed (S1103), and then the process returns to the payout launch control process of FIG.

  If the rotation of the payout motor 658a 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 658a is driven to execute the retry process and the payout motor 658a is stopped (S1105). Return to.

  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 658a is executed (S1107), and then the process returns to the payout discharge control process of FIG. On the other hand, if the payout has not been completed (S1106: No), the process returns to the payout launch control process of FIG.

  The lending control process shown in FIG. 60 will be described. In the ball lending control process, first, the payout motor 658a is driven to rotate in the reverse direction to pay out a lending ball (S1201). Whether the rotation of the payout motor 658a is normal is determined based on the detection result of the payout rotation sensor (S1202). If not normal (S1202: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a. The stop process is executed (S1203), and then the process returns to the payout / discharge control process of FIG.

  If the rotation of the payout motor 658a 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 658a is driven to execute a retry process and the payout motor 658a is stopped (S1205), and then the payout launch control process of FIG. Return to.

  Further, if the game ball count is normal (S1204: Yes), it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed ( If the payout has been completed (S1206: Yes), the payout motor 658a is stopped (S1207), and then the payout launch control process of FIG. 58 is returned to. On the other hand, if the payout has not been completed (S1206: No), the process returns to the payout launch control process of FIG.

  Next, with reference mainly to FIG. 1, FIG. 3, and FIG. When the player operates the operation handle 310 (see FIG. 1), a game ball is fired, and the fired game ball flows down the front of the game board 16 (see FIG. 3). When a game ball flowing down the front of the game board 16 enters one of the upper and lower start winning ports 331 and 332, the ball is detected by the start port switches 524a and 524b (see FIG. 41) and is detected by the main controller 561. A jackpot lottery will be held. Based on the lottery result of the jackpot lottery, the main control device 561 and the display control device 505 cause the first symbol display device 81 to perform variable display of the first symbol. When the jackpot lottery result is derived by the jackpot lottery of the main controller 561, a stop symbol in which three identical symbols stop on the active line in the first symbol variation display appears as a display result to the player. Will be won. In addition, when winning the jackpot lottery, the variable winning device 65 switches the specific winning opening 65a from the closed state to an open state advantageous to the player, and a special gaming state is generated, and the player receives a large amount of prizes as a predetermined gaming value. The ball is paid out.

  Further, the start winning opening that becomes the trigger of the big hit lottery is formed by two upper and lower start winning openings 331 and 332, and the lower start winning opening 332 pays out a large number of game balls from the upper start winning opening 331. The lower start winning opening 332 differs in ease of entering a game ball depending on whether the blade 333 is open or closed, and the operation of the blade 333 is controlled by the main controller 561. Is done. The operation of the blade 333 is performed under the condition that the game ball enters (passes) the second entrance 67.

  When a game ball enters the second entrance 67 and the entrance is detected by the second entrance detection switch 525, the main controller 561 determines whether or not the lower start winning entrance 332 is opened. A lottery is performed, and based on the lottery result, the main control device 561 and the display control device 505 cause the second display device 82 to perform the variable display of the second symbol. When the lottery result for opening the lower start winning opening 332 is derived by the lottery of the main controller 561, the display result that the second symbol variation display stops at the symbol “◯” appears and the player is selected. Is displayed, and the control of the main controller 561 switches the blade 333 from the closed state (see FIG. 4) to the open state (see FIG. 5) for a predetermined time, so that the game ball enters the lower start winning opening 332. An easy state is formed.

  Here, the lower start winning opening 332 where the game ball easily enters by the operation of the blade 333 based on the control of the main controller 561 is an area where a larger number of game balls are paid out than the upper start winning opening 331. . Also, during normal games other than short-time games, the variation time of the second symbol of one time is set to be long in 30 seconds, and the blade 333 hardly forms an open state, or only for a short time of 0.4 seconds. Since it is opened, little or no gaming ball enters the lower start winning opening 332. On the other hand, during the short-time game, the fluctuation time of the second symbol of one time is 5 seconds, and the blade 333 frequently forms an open state, and the open state is formed for 4 seconds for one win. Therefore, a large amount of game balls enter the start winning opening 332 below the normal game. In this way, the number of game balls to be paid out as the game balls enter the start winning ports 331 and 332 can be greatly varied depending on the operation of the blades 333, and the number of game balls to be paid out during normal games can be changed. Can be suppressed. Therefore, it is possible to suppress the decrease in game balls during the short-time game while increasing the probability of winning the big hit lottery to increase the probability of occurrence of the special game state.

  In addition, the variation display of the second symbol is performed by two types of variation patterns in which the length of the variation time is set to 5 seconds and 30 seconds. The variation pattern is selected by the main controller 561, and the variation pattern selection ratio is set to the normal game until the big winning opening 65a is finally opened during the big hit, and the normal variation pattern is fixed. (Ie, at a 100 percent ratio). After the jackpot is over, it becomes a short-time game, and the shortened variation pattern is selected at a rate of 100%. For this reason, after the jackpot is ended, the variation display by the shortened variation pattern having a variation time shorter than that during the jackpot is performed. Therefore, the opportunity for the blade 333 to be in an open state is increased when the game ball enters the second entrance 67, and it is difficult for the game ball to enter the lower start entrance 332 during the big hit. By reducing the number of payouts, it is possible to generate a game with a large number of game balls to be paid out easily after the jackpot is over, so that the game balls can easily enter the lower start winning opening 332. As a result, the total number of game balls paid out by one jackpot can be prevented from varying due to the game balls entering the lower start winning opening 332, and the game balls won by one jackpot can be prevented. The total number can be made almost constant.

  Furthermore, when the fluctuation display by the shortened fluctuation pattern is performed after the big hit, the value of the short-time counter JN is updated in the middle of the big hit so that the second symbol fluctuation display is completed in a short time from the end of the big hit. Start a short game. For this reason, it is possible to prevent the second symbol variation display from being performed for a long time from the jackpot end time as compared with the case where the time-saving game is started by updating the value of the hourly counter JN at the timing when the jackpot ends. can do. Therefore, when a short-time game is performed immediately after the jackpot ends, it is possible to provide the player with a game in which the decrease in game balls is suppressed by the short-time game at that time. Note that it is not always necessary to start the time-saving game by updating the value of the time-saving counter JN at the timing when the final round of jackpot is started, and another round close to the final round (for example, the round before the final round) You may be allowed to start a short-time game.

  Next, a pachinko machine according to the second embodiment will be described. The pachinko machine in the second embodiment is a part of the jackpot process of the main controller 561 for the pachinko machine 10 of the above-described embodiment (hereinafter referred to as “first embodiment” as appropriate) Only a part of the processing of the display control device 505 that operates based on the processing is different. Hereinafter, the same parts are denoted by the same reference numerals, description thereof is omitted, and only different parts will be described.

  In the jackpot process (S206) in the first embodiment, the value of the short-time counter JN is updated at the timing when the big winning opening 65a is opened in the final round by the processes of S549 and S550, and the variation of the second symbol after the jackpot The display was quickly stopped, and the player was provided with a gameability in which a decrease in the number of game balls was suppressed by a short-time game. On the other hand, in the jackpot processing (S2000) of the pachinko machine in the second embodiment, there is more time than the fixed time (5 seconds in the present embodiment) at the timing of the jackpot end, and there is remaining time for fluctuation display of the second symbol. In this case, the remaining time of the variable display of the second symbol is changed to a short time (for example, 5 seconds). The jackpot process (S2000) in the second embodiment is obtained by deleting the processes of S549 and S550 and adding the processes of S2001 to S2004 to the first embodiment.

  FIG. 61 is a diagram showing a jackpot process (S2000) of the pachinko machine according to the second embodiment. In the jackpot process (S2000) in the second embodiment, when the execution time of the end effect has passed in the process of S553 and it is time to end the jackpot (S553: Yes), after the jackpot flag 703b is turned off ( S554), it is determined whether or not the value of the second variation time counter HD2 is greater than 1250 (S2001). Since the value of the second variation time counter HD2 is updated every 4 ms, when the value of the second variation time counter HD2 is greater than 1250, the remaining time of the variation display of the second symbol is 5 seconds or more It is.

  When it is determined that the value of the second variation time counter HD2 is larger than 1250, that is, the remaining time of variation display of the second symbol is more than 5 seconds (S2001: Yes), 1250 is set to the second variation time counter HD2. Writing (S2002), the remaining time of the variable display of the second symbol is 5 seconds. Further, the second variation shortening command is set (S2003), and the display control device 505 is also instructed to set the remaining time of variation display of the second symbol to 5 seconds. Thereafter, “100” is written in the value of the time-count counter JN (S2004), and the jackpot processing (S2000) is terminated.

  When it is determined that the value of the second variation time counter HD2 is 1250 or less (S2001: No), the processing of S2002 and S2003 is skipped, and “100” is written to the value of the time reduction counter JN (S2004). ), The jackpot processing (S2000) is terminated. If the value of the second variation time counter HD2 is 1250 or less in the process of S2001, the variation display of the second symbol is stopped within 5 seconds thereafter, so the opening timing of the lower start winning opening 332 is delayed. This is because there is little influence by this.

  Thus, in the pachinko machine in the second embodiment, the variation display of the second symbol is being executed at the timing of the jackpot end, that is, the timing when the variation display of the first symbol is first started after the jackpot game. A process of determining whether or not the remaining time of the variable display is a predetermined time (for example, 5 seconds) or more (S2001), and when it is determined by the process that the remaining time of the variable display is a predetermined time or more And a process (S2002) of shortening the fluctuation time of the fluctuation display of the second symbol from the fluctuation time (30 seconds) based on the normal fluctuation pattern. For this reason, if the variation display time of the second symbol which is being executed at the timing when the first symbol variation display is first started after the jackpot is longer than 5 seconds, it is shortened to 5 seconds, and the jackpot end timing Therefore, the display result of the variation display of the second symbol is easily displayed in a short time. Accordingly, an open state in which the lower start winning opening 332 is opened after the big win is easily formed, and when a short-time game is played immediately after the big win ends, a game in which a decrease in game balls is suppressed by the short game at that time Sex can be provided to the player.

  Note that it is not always necessary to change the remaining time of the variable display of the second symbol depending on whether the remaining time of the variable display of the second symbol is 5 seconds or not, even if it is 4 seconds or less, 6 seconds or 7 seconds, etc. It may be. In the process of S2002, it is not always necessary to write a constant value so that the fluctuation display of the second symbol stops after a certain time from the end of the jackpot. , “1000”) may be subtracted to change the remaining time of the fluctuation display of the second symbol. Further, in the process of S2002, “0” may be written to the second variation time counter HD2, and the variation display of the second symbol may be stopped simultaneously with the end of the big hit game.

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

  For example, as shown in the above-described embodiment, the variable display, which is a kind of dynamic display, is not limited to the one in which the symbol as identification information is scrolled in the vertical direction on the display screen of the first symbol display device 81. It may be performed by moving and displaying a symbol along a predetermined route such as a direction or an L shape. In addition, the dynamic display of identification information is not limited to the display of variable symbols. For example, one or a plurality of characters may be displayed in various manners along with or separately from the symbols. The effect display etc. which are displayed are also included. In this case, one or a plurality of characters are used as identification information together with the symbols or separately from the symbols.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that generates a special game that gives a player a predetermined game value on the condition that a ball is won in a predetermined area. Further, the present invention may be implemented in a pachinko machine that has a special area such as a V-zone and has a special gaming state as a necessary condition for winning a ball in the special area. Further, in addition to pachinko machines, various game machines such as alepatchi and sparrow balls may be implemented.

  The gaming machine and modified examples of the present invention are shown below. In the following, for the sake of easy understanding, the correspondence between the requirements constituting the gaming machine of the present invention and the configuration of the embodiment of the invention corresponding to each structural requirement is appropriately indicated in parentheses. Each constituent requirement is not limited to the specific configuration shown in FIG.

  A game area that is formed so as to be visible to a player and where a game ball flows down and a game is played, a first start area provided in the game area, and a game ball entering the first start area First detection means for detecting, first lottery means for performing lottery when the first detection means detects entry of a game ball into the first starting area, and detected by the first detection means A first display device that dynamically displays first identification information based on a game ball entering and displays a display result corresponding to the lottery result of the first lottery means after the dynamic display, and the first display device It is advantageous for the player from the first state on condition that the display content of the display device is controlled based on the lottery result of the first lottery means, and that the predetermined lottery result is derived by the first lottery means. Present to the player by switching to the second state A variable winning means for generating a special game state, and when the predetermined lottery result is derived, a predetermined display result is displayed in the dynamic display and a predetermined prize is given to the player by the variable winning means. In a gaming machine that imparts a gaming value, a first ball entering portion that forms one of the first starting regions and one of the first starting regions provided at a position different from the first ball entering portion A second pitching portion in which a large number of game balls are paid out from the first pitching portion on the basis of the pitching of the game balls, and the pitching of the game balls into the second pitching portion. Limiting the entrance ball limiting means, deriving means capable of deriving the game ball to the second entrance part while avoiding the restriction by the entrance restriction means, and the game ball entering the second entrance part Difficult first derivation state and second derivation from which the first derivation state makes it easier for a game ball to enter the second entry portion Gaming machine 1, characterized in that it comprises a derivation switching means for switching the derivation means on purpose. In the gaming machine 1, the special gaming state is a display result corresponding to the lottery result after dynamic display of the identification information based on the winning even if the winning is not the jackpot, as well as the state in which the jackpot is being played Is displayed and includes a game state advantageous to the player who makes the transition.

  The gaming machine 1 includes a gaming board that is formed in a flat plate shape that forms the gaming area on one side and is arranged along a substantially vertical direction when the gaming machine is installed, and the first display device includes the gaming board surface. A first stage member provided on the upper side of the first incoming ball portion and between the first display device and the first incoming ball portion so that a game ball can roll to the first incoming ball portion; And a second stage member that forms one of the derivation means and is capable of rolling a game ball to the second entrance part, wherein the derivation switching means is a second stage member of the derivation means. 2. A gaming machine 2 configured to make it easier for a game ball to flow into the second stage member in a two-derived state. In the second derivation state of the derivation means, the derivation switching means is configured to make it easier for the game ball to flow into the second stage member, thereby playing the game from the first derivation state (normal game state) to the second ball entry portion. It can be formed by switching between a second lead-out state (for example, a short-time gaming state) in which a large amount of balls can easily enter. Therefore, in the first derivation state (normal game state), by making it difficult for the game ball to flow into the second stage member, the game ball is only in the first entrance portion where the number of payout of the game ball based on the entrance is small. It is possible to increase the probability of winning in the special game state without reducing the total number of game balls that can be acquired by the player for one special game state so as to hardly enter the ball. On the other hand, during the second lead-out state (short-time game state), a game ball is caused to flow into the second stage member, and a large number of game balls are also placed in the second ball-throwing portion where the number of payouts based on the game ball is large. By entering the game, it is possible to realize a game state in which game balls are difficult to decrease. Therefore, the number of game balls to be paid out when entering the first starting area can be greatly varied by the operation of the derivation switching means, and the number of game balls to be paid out during the first derivation state (normal game state) is suppressed. Thus, it is possible to suppress a decrease in game balls in the second derived state (short-time game state) while increasing the probability of occurrence of the special game state.

  In the gaming machine 2, a second start area provided separately from the first start area in the game area, a second detection means for detecting the entry of a game ball into the second start area, and the second A second lottery means for performing a lottery when a detection means detects the entry of a game ball into the second starting area, and a second based on the entry of the game ball detected by the second detection means. A second display device that dynamically displays the identification information and displays a display result corresponding to the lottery result of the second lottery means after the dynamic display, and the display contents of the second display device as the second lottery means And a second display control means for controlling the second display device to display a specific display result on condition that the second lottery means derives a predetermined lottery result, and the derivation Form one of the means, closed state and A derivation assisting member that can be driven from the closed state to an open state in which a game ball easily flows into the second stage member, and the derivation assisting member in the closed state on condition that a predetermined lottery result is derived by the second lottery means Auxiliary member switching means for switching from the open state to the open state for a predetermined time, wherein the derivation switching means is a period of the open state of the derivation auxiliary member by the auxiliary member switching means in the second derivation state of the derivation means ( (Or open area) is set longer (or larger) than the first derived state. In the second derivation state of the derivation means, the derivation switching means determines the open state period (or open area) of the derivation auxiliary member by the auxiliary member switching means based on the lottery result of the second lottery means. It is set longer (or larger) than the state. Therefore, in the first derivation state (normal game state), by making it difficult for the game ball to flow into the second stage member, the game ball is only in the first entrance portion where the number of payout of the game ball based on the entrance is small. It is possible to increase the probability of winning in the special game state without reducing the total number of game balls that can be acquired by the player for one special game state so as to hardly enter the ball. On the other hand, during the second derivation state (short-time gaming state), the period of the open state of the derivation auxiliary member (or the open area) by the auxiliary member switching unit based on the lottery result of the second lottery unit is changed to the first derivation state ( By setting (longer or longer) longer than the normal game state), the game ball is caused to flow into the second stage member, and a large number of game balls are also placed in the second ball-throwing portion where the number of payouts based on the game ball is large. By entering the game, it is possible to realize a game state in which game balls are difficult to decrease. Therefore, the number of game balls to be paid out when entering the first starting area can be greatly varied by the operation of the derivation switching means, and the number of game balls to be paid out during the first derivation state (normal game state) is suppressed. Thus, it is possible to suppress a decrease in game balls in the second derived state (short-time game state) while increasing the probability of occurrence of the special game state.

  In the gaming machine 3, the derivation switching unit has an open area formed by the open state of the derivation assisting member when the derivation assisting member is in the open state in the first derivation state of the derivation unit. The gaming machine 4 is characterized by being smaller than the outer diameter of the game ball. In the first derivation state of the derivation means, when the derivation auxiliary member is switched from the closed state to the open state for a predetermined time on condition that the second lottery means derives a predetermined lottery result, the opening formed by the open state of the derivation auxiliary member The area is made smaller than the outer diameter of the game ball. By configuring in this way, during the first derivation state (normal game state), the open state of the derivation auxiliary member by the auxiliary member switching means is determined from the outer diameter of the game ball based on the lottery result of the second lottery means. By reducing the size, it is possible to make it difficult for the game ball to flow into the deriving means and to make it difficult for the game ball to be led to the second entrance portion. Therefore, the number of game balls to be paid out when entering the first starting area can be greatly varied by the operation of the derivation switching means, and the number of game balls to be paid out during the first derivation state (normal game state) is suppressed. Thus, it is possible to suppress a decrease in game balls in the second derived state (short-time game state) while increasing the probability of occurrence of the special game state.

  The gaming machine 1 includes a gaming board that is formed in a flat plate shape that forms the gaming area on one side and is disposed along a substantially vertical direction when the gaming machine is installed, and the first display device includes the gaming board surface. A first stage member provided on the upper side of the first incoming ball portion and between the first display device and the first incoming ball portion so that a game ball can roll to the first incoming ball portion; The first stage member is provided to form one of the lead-out means, and a lead-out part capable of leading the game ball to the first ball-in part or the second ball-in part is provided. The gaming machine 4 is characterized in that the derivation switching means is configured to switch a derivation direction by the derivation unit. In the first derivation state of the derivation means, the derivation switching means makes it easier for the derivation unit to allow the game ball to flow into the first ball entry part, while in the second derivation state of the derivation means, the derivation part causes the derivation part to move to the second ball entry part. By making it easy to allow the game balls to flow in, the second lead-out state (for example, the short-time game state) in which a large amount of game balls can easily enter the second ball-entry portion from the first lead-out state (normal game state). And can be switched. Therefore, in the first derivation state (normal game state), the derivation unit makes almost no game ball enter only the first entrance part where the number of payout of game balls based on the entrance is small. The winning probability of the special game state can be increased without reducing the total number of game balls that the player can acquire for the special game state. On the other hand, in the second derivation state (short-time game state), the derivation unit causes a large number of game balls to enter the second entrance part having a large number of payouts based on the entry of game balls, thereby playing the game balls It is possible to realize a gaming state where it is difficult to decrease. Therefore, the number of game balls to be paid out when entering the first starting area can be greatly varied by the operation of the derivation switching means, and the number of game balls to be paid out during the first derivation state (normal game state) is suppressed. Thus, it is possible to suppress a decrease in game balls in the second derived state (short-time game state) while increasing the probability of occurrence of the special game state.

  In any one of the gaming machines 1 to 4, the first incoming ball portion is one in which one game ball is paid out based on an incoming game ball, and the second incoming ball portion has four or more balls. A gaming machine 5 in which game balls are paid out. Since the first pitching portion is for paying out a minimum number of game balls as the number of payouts, the probability of occurrence of a special game state based on the lottery of the first lottery means can be set higher. In addition, since the second pitching portion pays out four or more game balls corresponding to four times or more of the first pitching portion, when a short-time game is performed immediately after the end of the special game state, A decrease in game balls can be more reliably suppressed.

  In any one of the gaming machines 1 to 5, a gaming board is formed that is formed in a flat plate shape that forms the gaming area on one side, and is arranged along a substantially vertical direction when the gaming machine is installed. A game characterized in that the first and second balls are formed on the side and the second ball is formed side by side on the lower side of the first ball portion. Machine 6. Since the first entrance portion and the second entrance portion are arranged side by side, the player can confirm the entrance of the game ball into the first entrance portion and the second entrance portion. This can be done by moving the line of sight.

  The gaming machine 7 according to any one of the gaming machines 1 to 6, wherein the gaming machine is a pachinko machine. In particular, the basic configuration of a pachinko machine is provided with an operation handle, and in response to the operation of the operation handle, a game ball is launched into the game area, and the game ball enters a start area arranged at a predetermined position in the game area. A prerequisite is that the identification information dynamically displayed on the display device is confirmed and stopped after a predetermined time, assuming that a ball (winning at the start opening or passing through the start gate) is a necessary condition. In addition, when a predetermined game value is given, a variable winning device arranged at a predetermined position in the game area as a variable winning means can open a specific winning opening and win a game ball, and according to the winning number Examples include those to which valuable value (including data written on a magnetic card as well as premium balls) is given.
