Description

  The present invention relates to an opening / closing device that opens and closes a grand prize opening opening / closing door that opens and closes during a special game performed according to a lottery result when a game ball enters a start opening.

  In a gaming machine in which a special game is executed according to the lottery result when the game ball enters the starting port, in addition to the long hit game for the purpose of causing the player to acquire a prize ball, A plurality of types of special games such as a short hit game having a different purpose or a small hit game are set. In such a special game, a prize ball corresponding to the number of game balls entered in the big prize opening is paid out to the player by opening the big prize opening normally maintained in a closed state.

  A game per long is a game in which a round game in which the big prize opening is kept open is repeated several times until a predetermined number of game balls enter or until a predetermined time elapses. By doing so, the player can acquire a large amount of prize balls.

  On the other hand, in the short win game, as in the long win game, the round game is executed a plurality of times, but the time for which the big prize opening is kept open is short, so that almost no game balls enter the big prize opening. In a short hit game, the player can hardly obtain a prize ball. However, when winning a short win, the winning probability of the jackpot changes after the short hit game ends, and the low probability game state changes from the low probability gaming state in which the game progresses at a preset probability. A transition is made to a high probability gaming state in which the winning probability of jackpot is higher than the state, or a transition is made from a high probability gaming state to a low probability gaming state.

  In the small win game, as in the short win game, the opening / closing operation of the big winning opening is performed, but since the opening / closing operation of the big winning opening is set to be the same as or similar to the short winning game, The difference from the game is indistinguishable or difficult for the player. However, even if winning a small win, the winning probability of winning a big win does not change before and after winning a small win, so this is different from the short win.

  Because it is difficult for a player to determine whether he has won a small win or a short win, the player may have won a short win that has shifted to a high-probability gaming state from the opening / closing operation of the big prize opening. There is a sense of expectation that there is not, and anxiety that it may have shifted to a low-probability gaming state.

  In this way, when multiple types of special games are provided, if a special game with a different number of round games is provided, when the right to execute a special game is acquired (at the time of winning the jackpot), the round It is necessary to inform the player how many times the game can be executed by a lamp or the like. For example, in a gaming machine in which the game per long is set to 15 rounds and the game per short game is set to 2 rounds, the lamp for 15 rounds is turned on when winning per long and 2 when winning per short The round lamp will be turned on.

  On the other hand, since the small hit is different from the big hit such as long hit or short win, the round lamp cannot be turned on even when winning. For this reason, if the operation mode of opening / closing the big prize opening is the same for the small win game and the short win game, it is possible to determine which player has won from the lighting of the round lamp. If something is known, it may cause the player to lose the incentive to continue playing.

  Therefore, if the number of rounds in the short win game is the same as the number of rounds in the long hit game, it is considered unnecessary to inform the player of the number of round games executed, but the long win game is awarded to the player. Since the goal is to pay out the ball, the number of rounds cannot be reduced. After all, in order to make the number of rounds in the game per long and the game per short, it is necessary to match the number of rounds in the game per short with the game per long game. It is necessary to increase the number of times, that is, to open and close the large winning opening (opening / closing door) at high speed.

  The opening and closing of the prize winning opening is performed by opening and closing the opening and closing door of the winning prize opening unit (attacker unit) installed on the back of the game board, but when the opening and closing door is opened and closed, the game ball bites between the glass plate The operation member that opens and closes the open / close door supports the supported portion of the open / close door with some clearance so as not to cause a situation (see Patent Documents 1 to 3).

  Specifically, the open / close door opens and closes when a pin-shaped locked portion (supported portion) is supported by a bifurcated locking portion of the operation member so as to rotate or reciprocate. Is formed larger than the diameter or width of the locked portion, and a certain amount of clearance is secured between the locked portion and the supported portion.

  In addition, some gaming machines of this type are provided with two large winning mouthpieces for the purpose of improving game playability, and the game balls that have won the prizes are provided corresponding to the respective roles. It is generally detected by a detection sensor (refer to Patent Document 4), and a gaming machine equipped with two big winning mouthpieces has one big winning mouth piece in the gaming machine. In comparison, there are disadvantages that the number of parts is increased and that a space for arranging other items other than the prize winning combination is reduced. In view of this, as a means for suppressing the increase in the number of parts while securing the arrangement space for other bonuses, a prize winning combination that combines two prize winning combinations can be considered.

JP 2001-46693 A (paragraphs 0042-0055, FIGS. 6-8) JP 2001-327687 A (paragraphs 0007 to 0013, FIGS. 3 to 8) JP 2002-35386 (paragraphs 0029 to 0052, FIGS. 3 and 4) Japanese Patent Laying-Open No. 2003-310921 (paragraphs 0035 to 0037, FIG. 2)

  When the locked part of the door and the locking part of the operating member are locked with a clearance as described above, the locked door is locked when the operating member moves a distance exceeding the clearance. After the operation member is stopped by opening and closing the opening and closing door by engaging with the part, the opening and closing door is opened and closed excessively by the clearance. Therefore, it is impossible to open and close the large winning opening (opening / closing door) at high speed. For this reason, there is a demand for a large winning opening / closing device capable of opening and closing the large winning opening at a high speed even with clearance.

  In addition, when a detection sensor corresponding to each big prize opening role is provided in the big prize opening combination that combines the two big prize opening titles, it enters the big winning opening of one of the big prize winning points. Even if the game ball passes through the detection sensor corresponding to the other big prize opening role, the other big prize opening role is in the non-actuated state, so that this won game ball is not detected. As a result, a smaller number of prize balls than the number corresponding to the number actually won will be paid out, causing the player to feel uneasy, and if the number is found to be small, the incentive to continue the game will be lost. there is a possibility. Therefore, even when only one detection sensor of the other prize winning hole role is activated when one big prize opening role is activated, the detected game ball wins the big prize opening of the other big prize opening role. The game ball is counted as a game ball, and the same result as in the case where the above-described detection sensor does not detect a winning game ball is brought about.

  In accordance with the above-mentioned background, the present invention is provided with a prize winning combination in which two prize winning combinations are combined, can open and close the prize winning opening at a high speed, and is opened when one of the prize winning features is operated. The present invention proposes a large winning opening / closing device capable of paying out winning balls corresponding to the number of game balls won in the large winning opening.

The pachinko gaming machine according to claim 1 is a start area in which a game ball flowing down a game area can pass, a closed state in which a game ball flowing down the game area can not pass, or an opening in which a game ball can pass a first and second special winning opening displaced in the state, has a door before falling type, is tilted to the door in the longitudinal direction, the first bonus prize hole that performs opening and closing of the first bonus prize hole An opening / closing device and a sliding member that is slidable in the front-rear direction with respect to the opening / closing door are protruded from a second large winning opening provided on the opening / closing door and having a size that allows the sliding member to slide. opening to the second second and bonus prize hole opening and closing apparatus which performs opening and closing of the special winning opening, the first first detecting means capable of detecting a gaming ball having passed through the winning opening by, and the second bonus prize hole A second detecting means capable of detecting a game ball that has passed through; Extending outwardly of the second bonus prize hole hole on the surface from the distal end side of the door toward the proximal end, the game balls that winning in the first bonus prize hole opening and closing door is formed in a state of open A guiding member for guiding to the first detecting means side, special game determining means for determining whether or not to execute a special game advantageous to a player by passing a game ball through the starting area, and the special game determination Special game execution means for displacing the first or second big prize opening to the open state when it is determined by the means that the special game is to be executed, the special game execution means is the first game execution means . when displacing the special winning opening to the open state, the opening and closing operation of the first bonus prize hole opening and closing device, said first bonus prize hole to pass through the game ball easily Itay like, the first bonus prize hole first special game to be displaced to an open state, and the second special winning opening the To displace the released state, the opening and closing operation of the second bonus prize hole closing device, in the second hard aspect through the game ball into the special winning opening, a second for displacing the second bonus prize hole in an open state It is characterized by being able to execute at least a special game.

  The big prize opening / closing device is provided with a second big prize opening / closing device in the first big prize opening / closing device. The special prize opening / closing device is configured such that when one of the special prize opening / closing devices is operated and the open / close door or the slide member is in an open state, the other special prize opening / closing device is in an inoperative state. . For this reason, the first grand prize opening / closing device is operated to open the opening / closing door so that the game balls won in the first grand prize opening / closing device do not move to the second detecting means side of the second big prize opening / closing device. This is one of the objects of the present invention.

  The slide member is slidable in the front-rear direction with respect to the front-opening type opening / closing door, is supported so as to be movable along the slide rail, and is configured to be rollable via a roller. But you can. The second big prize opening hole provided in the opening / closing door of the first big prize opening / closing device may have a shape in which the slide member can move in the hole, and specifically, the moving direction of the slide member. A shape similar to a cross-sectional shape in a direction perpendicular to the direction is preferable. In addition, since the slide member is such that the game ball rolls on the slide member, the game ball passes through the second grand prize opening hole with the game ball entering the slide member. A possible size (height) is required.

Also, when the slide member moves and the second grand prize opening opens, the game ball moves on the slide member through the second big prize opening, but if the slide member is simply a plate-like member, the slide member A so-called spillover occurs in which the game ball moved upward falls from the slide member. For this reason, in order to prevent the game ball from being dropped, a front plate extending upward is provided at the front end of the slide member, and the side plate extending upward and in the front-rear direction on both sides of the shelf plate portion protruding from the lower portion of the front plate to the rear side. Department has preferably be provided.

  The second big prize opening is an opening / closing provided with the tip of the protruding slide member and the second big prize opening in the state where the slide member protrudes forward from the second big prize hole. An opening between the front of the door. When the second big prize opening is made large enough to allow a game ball to enter, the amount of protrusion of the slide member from the second big prize hole when the second big prize opening opens is larger than the diameter of the game ball. The sliding amount of the sliding member can be reduced as compared with the case where the second large winning opening has a size larger than the diameter of the game ball. For this reason, since the movement amount to which the slide member is moved is small, the slide member can be moved in a short time, and the moving speed of the slide member can be increased.

The first detection means and the second detection means are only required to be able to detect the winning game ball, and specifically, the game ball is detected from the change in the magnetic field generated when the game ball passes inside the coil. A magnetic sensor is preferred. The first detection means and the second detection means may be installed side by side, or may be installed shifted in the front-rear direction. The number of the first detection means and the number of the second detection means is at least one each, but is determined according to the degree to which the game balls won in the big prize opening hole are not stored in the big prize opening hole. More specifically, the first detecting means, a slide member in the central provided on both sides of the slide member, the second detecting means, Ru provided in the sliding direction rear side of the slide member.

  The guide member extends from the front end side of the open / close door to the base end side on the back surface of the open / close door in a state where the open / close door is open so that the game ball won in the first grand prize opening moves to the first detecting means side. The guide member may be one that extends linearly, one that a plurality of linear portions are continuously connected, one that is bent and extended, or one that is a combination of these. Further, when the door is closed, the guide member is disposed so as not to contact the front end portion of the slide member of the second prize opening opening / closing device, and specifically, outside the second big prize opening hole on the back surface of the opening / closing door. Arranged.

Further, when the first detection means is provided on both sides of the slide member with the slide member at the center and the second detection means is provided on the rear side in the sliding direction of the slide member, the guide member is in a state where the open / close door is opened. Thus, the first inclined surface portion that extends to one side in the width direction of the slide member as it advances to the rear side with respect to the opening / closing door, and the second inclined surface portion that extends to the other side in the width direction of the slide member as it advances toward the rear side with respect to the opening / closing door. DOO that is and a, provided on both sides of the second special winning opening hole of the rear surface of the door, extends outwardly of the front side portions of the slide member in a state where the door is opened, the first bonus prize hole made with a pair of plate members which prevent movement of the slide member side of the game ball with finishers is not good.

If the guide member has a pair of plate members, the plate member may come into contact with the game board side when the door is tilted in the closing direction. Therefore, Ru provided a groove through which the plate member that rotates with the tilt of the door on the game board side. The shape of the groove is determined according to the cross-sectional shape of the plate member orthogonal to the rotation direction of the plate member. If the cross-sectional shape of the plate member is rectangular, the groove is also formed in a rectangular shape. The plate member may have a height such that a gap between the upper surface of the first big prize hole and the upper end portion of the plate member is smaller than the diameter of the game ball with the open / close door open. preferable. By providing a plate member having such a height on the opening / closing door, it is possible to reliably prevent the game ball that won the first grand prize from moving to the slide member side beyond the plate member.

  According to the pachinko gaming machine opening / closing device of the pachinko gaming machine according to the present invention, the opening / closing operation of the first winning opening that allows the game ball to enter by opening the tilting forward opening / closing door in the front-back direction can be performed. A slide member that can slide in the front-rear direction with respect to the opening / closing door is opened in the first big winning opening / closing device to be opened by protruding from the second large winning opening, and a game ball enters.

A guide member that guides the game ball that has won the first grand prize opening formed in the state to the first detection means side. If the size of the second big prize opening opened by the movement of the slide member is such that the game ball can enter, the amount of movement of the slide member can be reduced and the slide member can be moved in a short time And the moving speed of the slide member can be increased. In addition, since the game balls won in the first grand prize opening are guided to the first detection means by the guide member, all the game balls won in the first big prize opening are detected by the first detection means. For this reason, it is possible to surely pay out the winning balls corresponding to the number of game balls won in the first big winning opening. In addition, since the game balls won in the first grand prize opening are distributed by the guide member and guided to the first detection means side, the game balls won in the first big prize opening are detected by the second detection means. Absent. For this reason, the game balls that have won the respective prize winning openings are reliably detected by the detection means corresponding to the prize winning openings, and the winning balls corresponding to the number of game balls that have won the prize winning openings can be paid out. it can.

The rear end portion of the shelf plate portion 921b extends to a position in the vicinity of the front side of the discharge port 904b with the slide member 921 moved to the storage position Pk. For this reason, even if the slide member 921 moves from the big prize opening position Pd to the storage position Pk, the rear end portion of the shelf plate portion 921b is located in front of the discharge port 904b, so that the discharge port 904b is always opened. Is in a state. Therefore, the game ball that has entered the slide member 921 is reliably detected by the second prize winning port second detection unit 224 ′ through the discharge port 904b.

  The side plate portion 921c has a height (for example, a height larger than the radius of the game ball) such that the game ball entered on the shelf plate portion 921b does not spill out. The side plate portion 921c extends to the back side of the case 904 with the slide member 921 moved to the storage position Pk, and the back side end portion of the side plate portion 921c is connected to an urging base 926 arranged on the back side of the case. Yes. The biasing table 926 will be described later.

  On both sides of the opening portion 924a of the second big prize opening hole 924 on the front surface of the open / close door 902, the second big prize opening hole is inclined to the opening portion 924a side of the second big prize opening hole 924 as it extends downward. A pair of guide plates 927 are provided for guiding the movement of the game ball to the slide member 921 that protrudes from the 924 and moves to the big prize opening position Pd (see FIG. 6A). The guide plate 927 has a flat upper surface, and its width direction length B (see FIG. 4) is substantially the same as the diameter of the game ball. The end of the guide plate 927 on the slide member side extends to a position close to the slide member 921 so that the guided game ball does not fall from the gap between the guide plate 927 and the slide member 921. .

  As shown in FIG. 1A, the back surface of the open / close door 902 is provided outside the opening 924a of the second prize winning hole 924, and extends from the front end side to the base end side of the open / close door 902 to open / close the open / close door 902. A guiding member 940 is provided for guiding a game ball that has won a first grand prize opening 903 formed in a state where the door 902 is opened to the big prize opening first detection unit 224 side.

  The guide member 940 has a first inclined surface portion 941 extending to one side in the width direction of the slide member 921 as it advances rearward with respect to the open / close door 902 in a state where the open / close door 902 is open, and a rear side with respect to the open / close door 902. The second inclined surface portion 942 that extends to the other side in the width direction of the slide member 921 as it proceeds to, and the tip end portions of the first inclined surface portion 941 and the second inclined surface portion 942 are connected to each other so as to be reversed in a plan view. It is configured symmetrically. For this reason, the first inclined surface portion 941 will be described, and the description of the second inclined surface portion 942 will be omitted.

  The first inclined surface portion 941 includes a linear portion 941a that is provided on the front end side of the opening / closing door 902 and extends linearly, and a bent portion 941b that is connected to the rear end portion of the linear portion 941a and curves outwardly. The rear end portion of the first inclined surface portion 941 is positioned on the outer side in the width direction of the slide member 921, as it advances from the front end side toward the rear end side and inclines toward the longitudinal end portion side of the door 902. For this reason, of the game balls that have won the first grand prize opening 903, the game ball that falls to the center in the longitudinal direction of the open / close door 902 contacts the outer surface of the first inclined surface portion 941 or the second inclined surface portion 942. However, it rolls and moves in the first big prize opening hole 905 and is detected by the big prize opening first detector (detector) 224 (see FIG. 4).

  The game ball that has dropped from above the guide member 940 and won the first big prize opening 903 falls below the game board 101 through the opening 924a of the second big prize opening hole 924. Furthermore, among the game balls won in the first grand prize opening 903, the game balls that fall on both sides in the longitudinal direction of the opening / closing door 902 move from the front side to the rear side of the first big prize opening hole 905, and the first prize winning hole first. It is detected by a detector (detector) 224 (see FIG. 4). For this reason, when the open / close door 902 is opened and the first grand prize opening 903 is opened, all the game balls won in the first grand prize opening 903 are detected by the big prize opening first detection unit (detector) 224. can do. For this reason, it is possible to reliably pay out the winning balls corresponding to the number of game balls won in the first big winning opening 903.

  7A (side cross-sectional view) and FIG. 7 (FIG. 7) are used as guide members for guiding all the game balls won in the first grand prize opening 903 to the first prize winning opening first detector (detector) 224 side. As shown in b) (plan sectional view), a pair of plate members 943 provided on both sides of the second large winning hole 924 on the back surface of the open / close door 902 may be used. The plate member 943 extends from the back surface of the open / close door 902 to the back side of the case 904, and is formed in a substantially rectangular shape in a side view. When the open / close door 902 is in an open state, the plate member 943 has a distal end extending along the slide member 921, and an upper end piece 943 a between the upper surface of the first big winning hole 905 and the upper end piece 943 a. The height H of the gap 944 is formed to be smaller than the diameter of the game ball. For this reason, it can prevent reliably that the game ball which won the 1st grand prize opening 903 moves to a slide member side exceeding a board member.

  Further, when the open / close door 902 is in a closed state, the front end side of the plate member 943 moves to the lower side of the case 904 and comes into contact with the game board side, so that the open / close door 902 cannot be closed. Therefore, a groove portion 946 is provided on the game board side through which the plate member 943 that rotates as the opening / closing door 902 tilts is passed. The groove portion 946 is formed in a rectangular shape in plan view and extends downward.

The biasing table 926 includes a bottom plate 926a that slides on the guide rail, and a connection plate 926b that is attached to the front side of the bottom plate 926a and extends upward to be connected to the rear end portion of the slide member 921. An operation member 923 for sliding the biasing table 926 on the guide rail is rotatably connected to the bottom plate 926a.

  The operation member 926 is a rod-shaped member, one end of which is rotatably supported by the connection plate 926b and the other end thereof is rotatably supported by the back end of the case 904. The other end portion is rotated as a rotation fulcrum O and the slide member 921 is moved via the biasing table 926. The operation member 926 supports the connection plate 926b by providing a shaft portion (not shown) projecting downward at one end of the operation member 926, and providing a hole portion (not shown) into which the shaft portion can be inserted into the connection plate 926b. By providing and inserting the shaft portion into the hole portion, one end side of the operation member 926 is rotatably supported.

  When the operation member 926 rotates about the rotation fulcrum O, the one end connected to the urging base 926 shifts with respect to the moving direction of the slide member 921 as the rotation angle increases, and the slide member 921 moves. It can be difficult. For this reason, the hole portion is formed in a long hole shape so that a clearance is formed between the shaft portion in a direction orthogonal to the moving direction of the slide member 921 (case longitudinal direction).

  A shaft 928a (plunger) of a special winning opening second opening / closing solenoid 928 for rotating the operation member 923 and sliding the slide member 921 is connected to the rotation fulcrum O side of the operation member 923. The grand opening second opening / closing solenoid 928 is disposed in the case 904 so that the shaft 928a faces the inner side of the case 904, and the operating member 923 is rotated as the shaft 928a expands and contracts to slide the slide member 921. Let

It is arranged in a locked state. The biasing member 930 is set so that the shaft 928a exhibits a restoring force from the immersive state to the protruding state.

  FIG. 4 shows the state of the slide member 921 when the special winning opening second opening / closing solenoid 928 is not energized (power OFF), and FIG. 5 shows the energization to the special winning opening second opening / closing solenoid 928 (power ON). The state of the slide member 921 is shown. In this example, when the shaft (plunger) 928a of the big winning opening second opening / closing solenoid 928 shown in FIG. 4 is projected, the slide member 921 is stored and the second big winning opening 922 (see FIG. 2) is closed. It becomes a state.

  When the power of the second prize opening second opening / closing solenoid 928 is turned on by a command from the main control board 201 described later, as shown in FIG. 5, the shaft 928a is immersed and the slide member 921 is slid to move to the second large size. When the winning opening 922 is opened and the power supply is switched from the ON state to the OFF state, the restoring force of the biasing member 930 causes the state shown in FIG. The winning opening 922 is closed.

  Switching the power ON / OFF of the large winning opening second opening / closing solenoid 928 of the second large winning opening / closing device 920 is instantaneously performed, and the opening / closing operation of the slide member 921 is performed 15 times in several seconds. The opening / closing operation of the slide member 921 at high speed is executed by the CPU 201a of the main control board 201 operating the short hit game control means 341 in the short hit game state as a result of the big hit lottery as will be described later.

Stop energizing. When either of these two conditions is satisfied, energization to the first prize opening first opening / closing solenoid 906 is stopped, the round game is ended, and the opening / closing door 902 enters a closed state in which the first first prize winning opening 903 is closed. .

  When a predetermined time (2 seconds) elapses after the open / close door 902 is closed, the CPU 201a activates the long hit game control means 340 to energize the first prize opening first open / close solenoid 906 again and open / close the door 902. Is opened and closed to open the first big prize opening 903. Thereby, the second round game is started. In this manner, the opening / closing operation of the open / close door 902 is repeated 15 rounds. When a game ball enters the first big prize opening hole 905 through the first big prize opening 903, a prize ball corresponding to the entered ball is The payout unit 291 pays out. Thus, in the long hit game, the player can acquire a large amount of prize balls.

  The short hit game control means 341 is configured to execute the short hit game when the right hit lottery lottery is triggered when a game ball enters the first start port 105 or the second start port 120. Control the progress of the hit game. The “short hit game” in the present embodiment is a kind of big hit game, and is a game in which the slide member 921 is opened and closed 15 times as in the above “long hit game”, and the round game is executed 15 times. However, in the “short hit game”, the maximum opening time of the slide member 921 is set shorter than the “long hit game”.

  The opening / closing operation of the slide member 921 in the “short hit game” state is performed by the second winning opening / closing solenoid 928 of the big prize opening. Specifically, when the CPU 201a operates the short hit game control means 341 to control the short hit game, first, the round winning game is performed by energizing the second prize opening / closing solenoid 928 to open the slide member 921. Be started. However, in the “short win game” state, the energization to the second winning opening / closing solenoid 928 is stopped for a moment (0.1 second), and then the energization control is repeated 15 times at a predetermined interval. ing. Therefore, the time during which the slide member 921 is in the open state is extremely short compared to the long hit game, and the possibility that the game ball enters the second big prize opening 922 is extremely low compared to the long hit game.

  In the “short hit game”, since the slide member 921 returns to the closed state in an instant, it is difficult for the player to recognize that the slide member 921 is opened. In this way, the “short win game” is aimed at improving the playability and the interest rather than paying the player a prize ball. However, even in the “short win game”, when a game ball enters the second big prize opening 922, a prize ball corresponding to the ball is paid out.

  The high-probability game control means 342 controls the game to a high-probability game state in which the game is progressed in a state where the winning probability of the big hit (including long win and short win) is higher than that in the normal game state. The high probability game state is executed after the long hit game or the short hit game is completed.

  Specifically, when a game ball enters the first start opening 105 or the second start opening 120, the first special symbol lottery means 300 or the second special symbol lottery means 320 acquires a winning random number. Then, the first random number determination unit 303 or the second random number determination unit 323 determines the acquired hit random number based on a predetermined table. At this time, in a normal gaming state (including a short-time gaming state that is not a high-probability gaming state, hereinafter referred to as a low-probability gaming state), a hit random number is determined based on a special symbol normal hour hit determination table. In the probabilistic gaming state, a hit random number is determined based on the special symbol high probability hourly determination table. In the special symbol high probability hourly determination table, the number (type) of random numbers for determining that the jackpot is larger than the special symbol normal hour determination table. The determination and type of jackpot will be described later in detail.

  The short-time game control means 343 is a program for controlling the short-time game. However, the short-time game in this embodiment is a state in which the normal symbol fluctuation control time by the normal symbol fluctuation control means 362 is short and the winning probability of winning in the normal symbol is high. Refers to the game. Specifically, it is as follows.

  When the game ball passes the winning gate 106, a normal symbol lottery is performed. The normal symbol lottery is performed by the CPU 201a operating the normal symbol lottery means 360 to randomly extract random numbers when the game ball passes through the winning gate 106. The random numbers obtained in this way are determined based on the normal symbol normal hour determination table in the normal gaming state (including the high-probability gaming state that is not the short-time gaming state). Is determined based on the normal symbol time per hour determination table.

  At this time, the normal symbol time per hour determination table is set with more random numbers for determining that the normal symbol normal time per hour determination table than the normal symbol normal time per hour determination table. Thus, the winning probability of the normal symbol in the short-time gaming state is as high as 90%, for example. However, when the normal symbol is won, the pair of movable pieces 120a of the second starting port 120 are opened for a predetermined time, and the game ball is It becomes easy to enter the second start port 120.

  Also, in the short-time gaming state, the variation time of the normal symbol is shortened compared to the normal gaming state. That is, when the game ball passes the winning gate 106, random numbers are acquired and the acquired random numbers are determined. At this time, the player is informed whether the result of the normal symbol lottery is a win or a loss. A predetermined time is required until notification. The time required for notifying the player of the result of the normal symbol lottery is set shorter in the short-time game state than in the normal game state, and in the short-time game state, the normal symbol lottery results are played one after another. And the second start port 120 is frequently opened. In this way, the short-time gaming state makes it easy for a game ball to enter the second starting port 120, so that the game state progresses in a state where the right of the big hit lottery can be obtained without spending much of the game ball. That is.

  The normal game control means 344 controls the progress of a normal game that does not correspond to either the big hit game (long win game, short win game) or the special game state (high probability game state, short-time game state). As described above, the CPU 201a operates any one of the long hit game control means 340, the short hit game control means 341, the high probability game control means 342, the short time game control means 343, and the normal game control means 344 to control the progress of the game. However, the current gaming state controlled by each of the control units 340 to 344 is written in the gaming state storage unit 404 of the RAM 201c.

  The small hit game control means 345 receives the right to execute the small hit game as a result of the big hit lottery triggered by the game ball entering the first start port 105 or the second start port 120. Control the progress of the hit game. In this small hit game, as with the short hit game, the sliding member 921 is instantaneously opened and closed for 15 rounds. In the small hit game, the number of times the slide member 921 is opened, the release time, and the release timing are exactly the same as those in the “short hit game”.

  Based on one of the above game states, a game related to a normal symbol and a game related to a special symbol proceed. Each of these game states will be described in detail below. First, the normal symbol lottery means 360, the normal symbol display control means 361, the normal symbol fluctuation control means 362, the normal symbol lottery result determination means 363, and the normal symbol hold storage means that start control when the game ball passes the winning gate 106. 403 will be described.

  When the gate detector 222 detects that the game ball has passed the winning gate 106, the normal symbol lottery means 360 acquires a random number of 1 from a random number prepared in advance (for example, 0 to 250). When the random number is acquired by the normal symbol lottery means 360, the normal symbol lottery result determination means 363 determines whether or not the winning is based on the table stored in the ROM 201b. At this time, if it is the normal gaming state, the winning is determined based on the normal symbol normal hour hit determination table, and if it is the time-short gaming state, the hit is determined based on the normal symbol short time hit determining table.

  If the result of the determination by the normal symbol lottery result determination means 363 is a win, the second start port opening / closing solenoid 120b is operated to open the movable piece 120a and maintain the open state. The control is terminated while the second start port opening / closing solenoid 120b is maintained in the closed state without being operated. The result of determination by the normal symbol lottery result determination means 363 is displayed on the normal symbol display 82 by the normal symbol display control means 361.

  When the game ball passes through the winning gate 106, the normal symbol display 82 is displayed with the lamp lit or flashing as if the lottery is currently being performed, and the lighting and flashing continued for a predetermined time. Later, the lottery result is finally displayed. This is normal symbol variation display, but the variation display time is preset for each gaming state.

  Specifically, in the short-time gaming state, the variation time of the normal symbol is set to be as short as 1.5 seconds, for example, and the probability of winning in the win is also set to a high probability of 90%. Therefore, in the short-time gaming state, as long as the game ball passes through the winning gate 106, the normal symbol lottery and the variation display are successively performed, and the time for the second start port 120 to be kept open becomes long. On the other hand, in game states other than the short-time game state, the variation time of the normal symbol is set to be as long as 10 seconds, for example, and the probability of winning a win is also set as low as 10%.

  In addition, when the normal symbol is won in the short-time gaming state, the second starting port 120 is opened four times for 1.2 seconds, whereas the normal symbol is won in the gaming state other than the short-time gaming state. However, the 0.2 second opening operation is performed only once. As described above, in the short-time gaming state, the time that the second start port 120 is in the open state is much longer than in the normal game state, and the possibility that a game ball enters the second start port 120 is also much greater. Get higher.

  If the game ball further passes through the winning gate 106 during the normal symbol fluctuation display, the right to draw the normal symbol lottery means 360, that is, the right to display the normal symbol fluctuation display, is reserved in the normal symbol hold storage means 403. The The maximum number of reserved rights for the lottery is four, and is displayed on the normal symbol hold display 92 by the normal symbol display control means 361.

  Next, the control when the game ball enters the first start port 105 or the second start port 120 will be described. For example, when the first start port detection unit 221 detects that a game ball has entered the first start port 105, a detection signal is transmitted to the main control board 201.

  When the detection signal is received, the first special symbol lottery means 300 extracts any random number (game data of the present invention) from random numbers (for example, 0 to 600) prepared in advance. The random numbers extracted here include a hit random number, a design random number, and a reach random number. The winning random number is a random number for determining whether or not a big hit, that is, whether or not a right to execute the big hit game is acquired. The design random number is the type of jackpot (long win, short win, presence / absence of transition to high-probability gaming state, presence / absence of transition to short-time gaming state), that is, what game value is given when winning the jackpot It is a random number to determine what will be done. The reach random number is a random number for determining whether or not to perform reach production.

  The RAM 201c of the main control board 201 is provided with a game state storage unit 404 that stores the current game state. When the first special symbol lottery means 300 or the second special symbol lottery means 320 acquires a random number, the first random number determination means 303 or the second random number is based on the gaming state stored in the gaming state storage means 404. The determination unit 323 determines the random number.

  Specifically, if it is a low-probability gaming state, the acquired random number is determined based on the special symbol normal hour determination table, and if it is a high-probability gaming state, the acquired random number is used for special symbol high-probability time determination. Determined based on the table. In the present embodiment, the same determination table is used when a game ball enters the first start port 105 and when a game ball enters the second start port 120. Different determination tables may be used depending on the start opening into which the game ball has entered.

  Each random number acquired by the first special symbol lottery means 300 or the second special symbol lottery means 320 and the determination table used when determining the acquired random number are as shown in FIG. FIG. 12 (a) shows an example of the jackpot winning probability and the winning random number, and FIG. 12 (b) shows an example of the type of gaming value given when the jackpot is won, the winning probability, and the design random number. FIG. 12C shows an example of presence / absence of reach effect, its appearance probability, and reach random number.

  As shown in FIG. 12A, one winning random number is acquired from 601 random numbers from 0 to 600. In the low probability gaming state, the hit random number is determined based on the special symbol normal hour hit determination table. According to the special symbol normal hour hit determination table, the two random numbers 7 and 317 are determined to be big hit. Is done. On the other hand, in the high-probability gaming state, the hit random number is determined based on the special symbol high-probability hourly determination table. According to this special symbol high probability per hour determination table, 7, 37, 67, 97, 127, 157, 187, 217, 247, 277, 317, 337, 367, 397, 427, 457, 487, 517, Twenty random numbers 547 and 577 are determined to be big hits.

  For example, when a game ball enters the first starting port 105, the CPU 201a activates the first special symbol lottery means 300 to acquire the winning random number. At this time, in the normal gaming state, the CPU 201a operates the first random number determination unit 303 to determine whether or not the winning random number hits or loses based on the special symbol normal time determining table. That is, if the winning random number acquired by entering the game ball into the first starting port 105 is 7 or 317, it is determined to be a winning, and if it is any other random number, it is determined to be lost. In the high probability gaming state, it is determined whether or not the winning is based on the special symbol high probability per hour determination table.

  In the present embodiment, a “small hit” is provided separately from the “big hit” described above, and the winning of the “small win” is also determined by a random number. The “small hit” in the present embodiment is to acquire the right to execute the “small hit game” in which the momentary opening operation of the slide member 921 is performed for two rounds, similarly to the short hit game. Therefore, as shown in FIG. 12 (a), regardless of the gaming state, when the winning random number is 50 or 100, a small winning game in which the slide member 921 is opened for 15 rounds is executed. Become. The small hit game is controlled by the CPU 201a operating the small hit game control means 345. Further, as will be described in detail later, this small hit game is not intended for paying out a prize ball, and the player recognizes that the gaming state has shifted to the high probability gaming state, as will be described later. It is provided for the purpose of making it difficult.

  As a result of the determination of the winning random number, when it is determined that the winning random number is a random number for acquiring the right to execute the jackpot game, the CPU 201a activates the first random number determining means 303, and FIG. The type of jackpot is determined (determined) based on. The types of jackpots determined here are "per length with high probability", "per length with normal", "short per period with high probability", "short per period with normal", "short per hour with high probability" ”And“ Normal short / short short hit ”.

  “Per probability with a short time with high probability” is a game to which three game values are given. If this “high probability per short with length” is won, as a first game value, the slide member 921 is controlled to open and close for 15 rounds, and a predetermined number (9) of game balls is set to finish one round. A long hit game is executed in which a predetermined time (30 seconds) elapses. As a result, the player can acquire a large amount of prize balls. When the long hit game ends, the game progresses in the high-probability gaming state as the second gaming value, and the game advances in the short-time gaming state as the third gaming value. As a result, the player can win a large amount of prize balls, and after winning the prize balls, can reduce the consumption of the game balls and realize a big win again early. The short-time gaming state, which is the third gaming value given here, continues until the jackpot is won.

“Regular per short time” is a game to which two game values are given. This “per length with a short time” is different from the above “per length with a short time with a high probability” in that the winning probability of the jackpot becomes a low-probability gaming state after the end of the game with a long time. Further, in the “per length with normal time saving”, the time-short gaming state after the end of the long winning game ends when a special symbol variation display is performed a predetermined number of times (for example, 100 times).
As described above, in the present embodiment, after the end of the long hit game in which a large amount of prize balls can be obtained, the long win in which the game progresses in the high probability game state where the winning probability of the big win is high, There is provided a long win in which the game progresses in a low-probability gaming state in which the winning probability is low.

  “Short per hit with high probability shortening” is a game that progresses in a high-probability gaming state in which the winning probability of jackpot is high after repeating the action of the sliding member 921 opening for a moment for 15 rounds. In the case of winning this “short win with high probability short time”, a large amount of prize balls due to the opening of the slide member 921 cannot be obtained immediately, but the subsequent gaming state becomes a high probability gaming state. There is a high possibility of winning a large number of prize balls in the game. In addition, if you win the “short win with high probability short-time”, the game ball will be in the high-probability gaming state at the same time as the winning or after the short win game, and will be in the short-time gaming state. Cost consumption can be reduced.

  "Short hit with normal time" is a game that progresses in a low-probability gaming state in which the winning probability of winning a jackpot is low after repeating the action of the sliding member 921 opening for a moment for 15 rounds. However, since the subsequent gaming state becomes the short-time gaming state in the same manner as the above “short chance with short time with high probability”, it is possible to reduce the consumption of gaming balls only for a predetermined number of times. In the normal game state, if the “short win with normal time” is won, the game value that enables execution of the short time game is only given thereafter, but in the high probability game state, If the player wins the “short win with normal time”, there is a demerit that the win probability of the jackpot will fall from a high probability to a low probability.

  In this embodiment, both the “short hit with normal time” and the “short hit with high probability” have an opening / closing operation of the slide member 921 and an opening / closing operation of the second start port 120 after shifting to the short-time gaming state. Are the same. Also, as will be described later, the production contents are the same for “short win with normal time” and “short win with high probability”. Therefore, for the player, after the short hit game (the 15-round opening / closing operation of the slide member 921) is completed, it is determined whether the winning probability of winning the jackpot is high or low. It has become very difficult. In this way, the reason for providing "short win with normal time" is whether the winning probability of jackpot is high probability or low probability when it becomes short-time game state after the short win game ends, This is to make the player have doubts.

  “Short per hit without high-probability time” is a high-probability gaming state in which the winning probability of jackpot is high after 15 rounds of the opening operation of the slide member 921 for a moment, similar to the above “Short per hit with high-probability time” It is a game that shifts to a so-called latent probability variation state. However, this “high probability short-time short win” is different from the above “high probability short-time short win” in that the short-time game is not started after the short win game ends. Even when this “high probability short / short short win” is won, a large amount of prize balls due to the opening of the slide member 921 cannot be obtained immediately. In addition, since it does not become a short-time gaming state thereafter, the consumption of the game ball is higher than “short hit with high probability short-time”. However, since the subsequent gaming state is a high-probability gaming state, there is a high possibility of winning a large number of prize balls by winning the long game in subsequent games.

  The “normal short time short hit” is a game that progresses in a normal game state after repeating the action of the slide member 921 opening for a moment for 15 rounds. In other words, even if the “normal short-time short win” is won, neither the high-probability gaming state nor the short-time gaming state is entered. Moreover, since it is impossible to obtain a large amount of prize balls by opening the slide member 921 for 15 rounds, the player is hardly given the game value due to the big win.

  The reason for providing such “normal time short hits” is mainly to return the gaming state from the high probability gaming state to the low probability gaming state without paying out a prize ball. In addition, even if the “normal time short no short win” is won in the normal gaming state, the gaming state does not change at all. Therefore, if the player is made indistinguishable from “short win without short time” and “short win without normal time”, will the winning probability of jackpot be high after the short win game ends? It can make the player doubt about whether the probability is low.

  In the present embodiment, in order to raise a suspicion about the fact that the winning probability of jackpot is high due to the winning of “high probability short / short short win”, Is provided with a “small hit”. However, since this “small hit” is not a kind of big hit, the small hit game is started when the hit random number (50, 100) is acquired instead of the symbol random number. In the “small hit game”, the operation of releasing the slide member 921 for a moment is repeated 15 rounds as in the case of winning the “normal short no hit short win”. However, this “small hit” is different from the above “normal short no hit short” in that the gaming state does not change at all after the sliding member 921 is opened and closed. In other words, if you win “Short win without normal time” in the high probability gaming state, the gaming state becomes the normal gaming state after the short winning game ends, but even if you win “Small hit” in the high probability gaming state Thereafter, the high-probability gaming state continues.

  When a game ball enters the first starting port 105, the CPU 201a activates the first special symbol lottery means 300 to acquire a reach random number together with the winning random number and the symbol random number. One reach random number is randomly acquired from 0 to 250 random numbers. The reach random number is determined as follows. That is, when the CPU 201a activates the first random number determination means 303 and determines that the winning random number is a loss, the reach random number is determined based on the reach random number determination table at the time of the loss, and is determined to be a big hit. In this case, the reach random number is determined based on the reach random number determination table for the big hit. In the reach random number determination table at the time of losing, a random number from 0 to 24 is determined as a reach effect, and other random numbers are determined as a reachless effect.

  Even when a game ball enters the second start port 120, the same control as described above is performed by the second special symbol lottery means 320 and the second random number determination means 323.

  On the other hand, when a game ball enters the first start port 105 or the second start port 120, if a special symbol change display is performed based on the previous game ball, it is acquired. The random number (game data) is stored in the first special symbol hold storage unit 401 or the second special symbol hold storage unit 402 of the RAM 201c. The first special symbol storage unit 401 and the second special symbol storage unit 402 are configured as shown in FIG.

  FIG. 13 is a diagram showing an example of a storage area related to the holding ball. As is clear from this figure, the first special symbol holding storage unit 401 detects that the game ball is detected by the first start port detector 221. Random numbers (hit random numbers, design random numbers, reach random numbers) acquired based on the fact are stored in association with the order in which game balls are detected as reserved balls. In other words, when a game ball enters the first start opening 105, the right of the special symbol change display is stored in the first special symbol hold storage means 401 as a so-called hold ball. The reserved balls retained in the storage unit 401 are digested and processed in the storage unit 401 in the order stored.

  Specifically, the first special symbol storage unit 401 includes four storage areas from the first storage area 401 a to the fourth storage area 401 d, each time a game ball enters the first start port 105. The reserved balls are retained in order from the first storage area 401a. That is, when a game ball enters the first start port 105 in a state where the reserve ball is retained in the first storage area 401a, the reserve ball is retained in the second storage area 401b. In this way, up to four reserved balls are reserved in the first special symbol storage unit 401.

  On the other hand, when a game ball enters the first starting port 105 in a state where the reserved ball is retained in all of the third storage area 401a to the fourth storage area 401d, a special symbol by the entry is displayed. The right to change is not reserved. In other words, if the number of reserved balls is retained up to the upper limit number of reserves in the first special symbol reservation storage means 401, even if a game ball enters the first start port 105, the big hit lottery by the entered ball is performed. I will not. However, even in this case, a predetermined number of prize balls for the game balls entering the first start port 105 are paid out.

  Further, the reserved ball retained in the first special symbol storage unit 401 is always digested (processed) from the first storage area 401 a by the first special symbol variation control unit 302. When the reserved sphere stored in the first storage area 401a is digested, the reserved sphere retained from the second storage area 401b to the fourth storage area 401d moves from the storage area to the previous area. That is, when the reserved sphere retained in the first storage area 401a is digested, the retained sphere retained in the second storage area 401b moves to the first storage area 401a. Similarly, the reserved ball retained in the third storage area 401c moves to the second storage area 401b, and the retained ball retained in the fourth storage area 401d shifts to the third storage area 401c. Accordingly, the fourth storage area 401d can accept the reserved ball again, that is, can reserve it.

  On the other hand, when a game ball enters the second start port 120, if the variation display based on the previous game ball is being displayed, the second special symbol storage unit 402 stores the game ball. Random numbers (hit random numbers, symbol random numbers, reach random numbers) acquired based on the detection by the second start-up port detection unit 225 are stored in association with the order in which game balls are detected as reserved balls. That is, when a game ball enters the second start port 120, the right of special symbol change display, that is, the right of jackpot lottery is stored in the second special symbol hold storage means 402 as a hold ball. The right to display the variation of the special symbol reserved in the storage area 402 is digested and processed in the storage area 402 by the second special symbol variation control means 322 in the stored order.

  Specifically, the second special symbol storage unit 402 includes four storage areas from the fifth storage area 402a to the eighth storage area 402d, and each time a game ball enters the second start port 120, The reserved balls are retained in order from the fifth storage area 402a. That is, when a game ball enters the second start port 120 in a state where it is retained in the fifth storage area 402a, a reserved ball is retained in the sixth storage area 402b. In this way, up to four reserved balls are reserved in the second special symbol storage unit 402. On the other hand, when a game ball enters the second starting port 120 in a state in which the reserve ball is retained in all of the fifth storage area 402a to the eighth storage area 402d, the change display of the special symbol is displayed. Rights are not reserved. In other words, if the number of reserved balls is retained up to the upper limit number of reserves in the second special symbol storage unit 402, even if a game ball enters the second start port 120, the big hit lottery by the entered ball is performed. I will not. However, even in this case, a predetermined number of prize balls for the game balls entering the second start port 120 are paid out.

  In addition, when a plurality of reserved balls are reserved in the second special symbol storage unit 402, it is digested from the fifth storage area 402a, but the reserved balls stored in the fifth storage area 402a are digested. Then, the reserved ball retained from the sixth storage area 402b to the eighth storage area 402d moves from the storage area to the previous area. That is, when the reserved sphere retained in the fifth storage area 402a is digested, the retained sphere retained in the sixth storage area 402b moves to the fifth storage area 402a. Similarly, the reserved sphere retained in the seventh storage area 402c moves to the sixth storage area 402b, and the retained sphere retained in the eighth storage area 402d moves to the seventh storage area 402c. Therefore, the eighth storage area 402d can accept the reserved ball again, that is, can reserve it.

  As described above, in the present embodiment, the storage area is divided for each start opening into which the game ball has entered, and the reserved balls are reserved. Therefore, the random numbers related to these hold balls and the start opening into which the game balls have entered are stored. It is stored in association with each other. However, as described above, the reserved balls may not be stored separately in the two storage units 401 and 402 but may be stored by other methods. For example, the reserved balls are retained in one storage means in the order in which the game balls enter the start opening. At this time, it may be stored in association with the holding ball which starting ball the game ball has entered, and the holding ball associated with the preset starting port may be preferentially processed.

  Each of the eight storage areas from the first storage area 401a to the eighth storage area 402d has a hit random number storage area, a design random number storage area, and a reach random number storage area, as shown in FIG. 13C. have. The winning random number storage area stores the winning random number, the symbol random number storage area stores the symbol random number, and the reach random number storage area stores the reach random number. As described above, when a reserved ball is reserved in the first special symbol storage unit 401, the CPU 201a operates the first special symbol display control unit 301 to determine the number of reserved balls that are reserved as the first special symbol. Displayed on the hold indicator 88.

  Note that the second special symbol lottery means 320 and the second special symbol display control means 321 also when a game ball enters the second start port 120 and the second start port detector 225 detects a game ball. The second special symbol variation control means 322 and the second random number determination means 323 perform the same processing as described above. However, the extracted random number is stored in any of the fifth storage area 402a to the eighth storage area 402d.

  When a plurality of reserved balls are reserved in the special symbol storage means 401, 402, the reserved balls are digested in the following order. That is, when the reserved ball is retained in both the first special symbol storage unit 401 and the second special symbol storage unit 402, the retained ball retained in the second special symbol storage unit 402 has priority. Digested. For example, as shown in FIG. 14 (a), the reserved balls are retained in the first storage area 401 a to the third storage area 401 c of the first special symbol storage unit 401, and the fifth special symbol storage unit 402 It is assumed that a reserved ball is reserved in the storage area 402a and the sixth storage area 402b.

  The order in which the game balls enter the first start port 105 and the second start port 120 is, as shown, the first start port 105 → the second start port 120 → the first start port 105 → the second start port. It is assumed that 120 → first start port 105. In the present embodiment, since the second start port 120 is the priority start port, in this case, the hold balls in the fifth storage area 402a are processed with priority, and the hold is performed in the order of the arrows shown in FIG. The ball is digested.

  For example, as shown in FIG. 14C, it is assumed that three reserved balls are reserved in the first special symbol storage unit 401 that performs non-priority processing. In this case, the three reserved balls retained in the first special symbol storage unit 401 are digested successively in the order indicated by the dotted lines in the figure. However, when the first reserved ball is digested, in other words, when the first special symbol variation display is performed, the reserved ball is stored in the second special symbol holding storage unit 402 to which priority processing is performed. Is retained (when the ball enters the second starting port 120), the reserved ball is interrupted, and the reserved balls are digested in the order indicated by the solid line in the figure.

  As is clear from this, when a plurality of reserved balls are reserved in the first storage area 401a where non-priority processing is performed in both storage means 401 and 402, the fifth storage area where priority processing is performed. There is a high possibility that an interruption process will be performed by holding the reserved ball at 402a. On the other hand, when a game ball enters the second start port 120, which is the priority start port, and a plurality of holding balls are reserved, no interruption processing is performed, and the plurality of holding balls are always continuous. To be digested.

  The retained balls are sequentially digested as described above. The CPU 201a controls the digestion of the retained balls, and the first special symbol variation control means 302 and the second special symbol variation control means of the ROM 201b. 322. Both of these fluctuation control means 302 and 322 monitor the first storage area 401a or the fifth storage area 402a to determine which reserved ball is to be processed.

  Next, the control when a game ball enters the starting port will be specifically described with reference to FIG. As shown in FIG. 15, first, the first start port detector 221 or the second start port detector 225 detects that a game ball has entered the first start port 105 or the second start port 120.

(Step S301)
Then, the CPU 201a of the main control board 201 operates a variation determination program (not shown) to determine whether or not the special symbol is being displayed in a variation manner. At this time, if it is determined that the special symbol is not in a variable display, the special symbol based on the incoming ball is immediately displayed, so that the fluctuation start process of FIG. 16 described later is performed.

(Step S302)
On the other hand, if it is determined in step S301 that the change is in progress, the first special symbol storage unit 401 or the second special symbol storage unit 402 stores a random number in the fourth storage area 401d or the eighth storage area 402d. Determine whether it is stored. Specifically, when a ball entry signal is received from the first start port detector 221, it is determined whether the number of reserved balls retained in the first special symbol storage unit 401 is less than 4, and the second start When the incoming signal is received from the mouth detector 225, it is determined whether or not the number of reserved balls in the second special symbol storage unit 402 is less than 4.

  If it is determined in step S302 that there are four reserved balls, a special symbol variation display, that is, a big win lottery will not be performed depending on the game ball's entry. The control on the main control board 201 is finished by paying out.

(Step S303)
On the other hand, if it is determined in step S302 that the number of reserved balls is less than 4, that is, it is determined that the reserved balls are reserved, the first storage area 401a to the fourth storage area 401d or the fifth storage area 402a to the eighth storage area. Game data (a hit random number, a design random number, a reach random number) is stored in 402d, and the reserved ball is reserved.
At this time, the CPU 201a activates a predetermined program, and the number of reserved balls retained is lit on the special symbol hold indicators 88 and 90. Thereby, the control in the main control board 201 is completed.

(Variation start processing)
Next, the control related to the special symbol variation display performed based on the game data, and the control related to the special game (long win game, short win game, small hit game) performed after the special symbol variation display is shown in FIG. This will be described with reference to FIG.

(Step S401)
First, when starting the special symbol variation display, game data (a winning random number, a design random number, a reach random number) is stored in a predetermined processing area of the RAM 201c in the main control board 201. Here, when the game ball enters the start port when the special symbol variation display is not performed, the CPU 201a operates the first special symbol lottery means 300 or the second special symbol lottery means 320 to play the game. Data is acquired, and this game data is stored in the processing area. On the other hand, when game data is stored in the first special symbol hold storage unit 401 or the second special symbol hold storage unit 402, the CPU 201a operates a predetermined program to store the first storage area 401a or the fifth storage. The game data stored in the area 402a is stored in the processing area.

(Step S402)
Further, when game data is stored in the first special symbol storage unit 401 or the second special symbol storage unit 402, each game data is shifted to the previous storage area. Specifically, in the above step S401, when the game data stored in the fifth storage area 402a of the second special symbol storage means 402 is stored in the processing area, the sixth storage area 402b to the eighth storage. The game data stored in the area 402d is shifted to the previous storage area. On the other hand, when the game data stored in the first storage area 401a of the first special symbol holding storage means 401 is stored in the processing area in the above step S401, it is stored in the second storage area 401b to the fourth storage area 401d. The stored game data is shifted to the previous storage area. However, if no game data is stored in the first special symbol hold storage unit 401 or the second special symbol hold storage unit 402, the process in step S402 is not performed.

(Step S403)
In step S401, when game data is stored in the processing area, the CPU 201a activates a predetermined program to determine whether or not the game state stored in the game state storage unit 404 is a high probability game state. However, here, there is no distinction between the high probability gaming state after the end of the long hit game and the high probability gaming state after the end of the short hit game.

(Step S404) (Step S405)
If it is determined in step S403 that the game state is not the high probability game state (low probability game state), the special symbol normal time determination table is selected. On the other hand, if it is determined in step S403 that the game state is a high probability game state (regardless of whether there is a short time game state), the special symbol high probability determination table is selected. The three tables selected here are a winning determination table for determining a winning random number, a symbol determining table for determining a symbol random number, and a reach random number determining table for determining a reach random number.

(Step S406)
Then, the CPU 201a operates the first random number determination unit 303 or the second random number determination unit 323, and determines each random number based on the table selected in step S404 or step S405. Thereby, whether or not the jackpot can be won, the type of jackpot in the case of winning the jackpot, and the aspect of the effect made during the change display of the special symbol are determined. Since each random number determination process is as described above, a description thereof is omitted here.

(Step S407)
In step S407, as a result of determining the reach random number, it is determined whether the effect mode is an effect with reach or an effect without reach.

(Step S408)
When it is determined that the effect mode is the effect with reach, the CPU 201a further operates the first special symbol lottery means 300 or the second special symbol lottery means 320 to acquire the effect random number. This effect random number is used to determine the time for displaying the variation of the special symbol, that is, the time (scale) of the reach effect. For example, one random number is randomly selected from 0 to 250 effect random numbers.

(Step S409)
When the effect random number is acquired, the effect random number is determined based on the effect random number determination table stored in the ROM 201b. For example, when the production random number is 0 to 50 production random numbers, the reach production time is determined to be 20 seconds, and when the production random number is 51 to 150, the reach production time is 30. When it is determined to be seconds and the effect random number is 151 to 250, the reach effect time is determined to be 60 seconds. Therefore, in this step S409, the time for the special symbol variation display, that is, the time for the reach effect is determined.

(Step S410)
On the other hand, if it is determined in step S407 that the effect is not a reached effect (a reachless effect), the CPU 201a activates a predetermined program to store the first special symbol hold means 401 and the second special symbol hold memory. The total reserved number of reserved balls of the means 402 is determined.

(Step S411)
Then, the CPU 201a operates a variation time determination program (not shown) to determine the variation time (effect time) of the special symbol based on the total number of reserved balls. For example, when the total number of reserved balls is 0 or 1 during the change start process, the change time is determined to be 12 seconds. Further, when the total number of reserved balls is 2, the variation time is determined to be 8 seconds and 3 or more to 4 seconds.

  In addition, when starting the variable display of the special symbol related to the reserved ball retained in the first special symbol storage unit 401, the variation time according to the number of reserved balls retained in the first special symbol storage unit 401 Is determined, and the variable symbol display of the reserved ball retained in the second special symbol storage unit 402 is started, according to the number of reserved balls retained in the second special symbol storage unit 402. The fluctuation time may be determined.

(Step S412)
As described above, when the time of the special symbol variation display (reach effect time, reach-less effect time) is determined, the CPU 201a activates the effect execution command transmission means 333 and sends the effect execution command to the sub-control board 202. Send. Each information based on the game data is attached to the effect execution command. Specifically, whether or not you win a jackpot (including a jackpot), if you win a jackpot, the type (long win, short win,), the mode of production (reach with reach or non-reach production Information regarding the time of the special symbol variation display, and information regarding the current gaming state stored in the gaming state storage unit 404.

(Step S413)
As described above, when the effect execution command is transmitted, the CPU 201a operates the first special symbol display control means 301 to start the special symbol display on the special symbol indicators 84 and 86. The special symbol variation display time is only the time determined in step S409 or step S411. After the time has elapsed, the special symbol indicators 84 and 86 have a symbol corresponding to the type of jackpot. Finally stop display.

(Step S414)
In addition, if the game data is a “big hit (long win, short win)”, it is necessary to start the jackpot game because the big jackpot game will start after the special symbol change display ends. Processing is performed. Therefore, here, it is determined whether or not the game data wins the “big hit”.

(Step S415)
If it is determined in step S414 that the “big hit” is not won, it is further determined whether or not the “small win” is won. Then, when the “small hit” is won, processing for starting the small hit game is performed after the special symbol variation display is completed. On the other hand, when neither “big hit” nor “small win” is won, the processing in the main control board 201 is ended.
When an effect execution command is transmitted to the sub-control board 202 in step S412, the sub-control board 202 displays the decorative symbol effects and effect actors 115 and 116 on the symbol display unit 104 during the special symbol variation display. The effect production by, other sound production and lamp production are controlled. This control will be described in detail later.

  In the special symbol variation start process controlled as described above, if the jackpot is won, after the jackpot special symbol is stopped and displayed, "long win game" or "short win game" starts Is done. If it is determined in step S414 that the big win is won, the RAM 201c stores whether the long win or the short win is identifiable. In the case of winning per long, the “long win game” is controlled as shown in FIG.

(Step S501)
First, at the start of control of the long hit game, the CPU 201 a operates the long hit game control means 340 and transmits a long hit effect start signal to the sub-control board 202. In the sub-control board 202, the effect during the long game is started by receiving the long effect production start signal. In the present embodiment, a movie is displayed on the symbol display unit 104 during a long game, the effect light 111 is lit corresponding to the movie, and music is output from the speaker 277. Such effects are consistently performed from the start to the end of the long hit game, but are controlled by the CPU 202a of the sub-control board 202 operating the effect control means 502.

(Step S502)
As described above, when an effect dedicated to a long hit game is started, the CPU 201a activates the long hit game control means 340 to start energizing the first prize opening first open / close solenoid 906 and rotate the open / close door 902. The first big prize opening 903 is opened. As a result, a game ball can enter the first grand prize winning hole 905.

  At the same time as energizing the first prize opening first open / close solenoid 906, a round start signal is transmitted from the main control board 201 to the sub control board 202. When the sub control board 202 receives the round start signal, the CPU 202a operates the effect control means 502 to control the effect for each round. For example, in the symbol display unit 104, a movie dedicated to a long game is already displayed, and a message such as “start one round” is displayed together with this movie.

(Step S503) (Step S504) (Step S505)
In step S <b> 502, when the first big prize opening 903 is opened by the rotation of the opening / closing door 902, the time counter provided on the main control board 201 starts measuring time. When the predetermined time (30 seconds) elapses, the CPU 201a activates the long hit game control means 340 to stop energization of the first prize opening first opening / closing solenoid 906 (step S505), and the opening / closing door 902 is closed. Similarly, the energization of the first prize opening / closing solenoid 906 for the special prize opening is stopped when the special prize opening detecting unit 224 detects the entry of a predetermined number (9) of game balls. Therefore, the control in steps S503 and S504 is repeatedly performed within a predetermined time after the opening / closing door 902 is opened and the number of game balls detected by the special winning opening detection unit 224 is less than the predetermined number. The open / close door 902 is maintained in the open state.

(Step S506)
Then, in step S505, when the energization of the first prize opening / closing solenoid 906 is stopped when the predetermined time elapses or the special prize opening detecting unit 224 detects a predetermined number of game balls, the CPU 201a The long hit game control means 340 is operated, and “1” is counted and stored in the round number storage means 405. The count value stored in the round number storage means 405 is used to determine how many rounds of the game per game have been played.

(Step S507)
Further, the CPU 201a operates the long hit game control means 340 to determine the count value stored in the round number storage means 405. If the count value is not 15, the processes in steps S502 to S506 are repeated.

(Step S508)
On the other hand, when the number of rounds reaches 15 as a result of repeating the processes of steps S502 to S507, the count value stored in the round number storage unit 405 is cleared.

(Step S509)
When the opening / closing operation of the open / close door 902 is performed a predetermined number of times (15 rounds), the long hit game is ended, and the CPU 201a activates the long hit game control means 340 to send a long hit game end signal to the sub control board 202. Send. Then, when the sub-control board 202 receives the long hit game end signal, the CPU 202b activates the effect control means 502, and the so-called long hit game end effect is performed.

(Step S510)
Further, the CPU 201 a operates the long hit game control means 340, and the subsequent game state is stored in the game state storage means 404. In the present embodiment, since the gaming state becomes the short-time gaming state after the end of the long hit game, the gaming state storage unit 404 stores a flag indicating that it is the short-time gaming state. In addition, when the long winning game related to the winning of “long probability with short time” ends, a flag indicating that the high probability gaming state is stored in the gaming state storage means 404, When the long winning game related to winning is completed, a flag indicating the low probability gaming state is stored.
In this way, when the process for proceeding with the subsequent game is performed, the control of the long hit game on the main control board 201 is finished.

  On the other hand, in the case of winning a short win, the “short win game” is controlled as shown in FIG.

(Step S601)
First, at the start of control of the short hit game, the CPU 201 a operates the short hit game control means 341 and transmits a short hit effect start signal to the sub-control board 202. In the sub control board 202, the effect during the short hit game is started by receiving the short hit effect start signal (step S601a). In the present embodiment, a movie is displayed on the symbol display unit 104 during the short hit game, the effect light 111 is turned on corresponding to the movie, and music is output from the speaker 277. Such effects are consistently performed from the start to the end of the short hit game, and are controlled by the CPU 202a of the sub control board 202 operating the effect control means 502.

  The short hit game is set in advance from the start to the end, and the short hit game-specific effect is set to the short hit game from the start to the end. As an effect dedicated to the short hit game, for example, an effect related to the opening at the time of starting a “probability change suggestion effect mode” described later is suitable.

  In the sub control board 202, when the short hit effect start signal is received, the CPU 202a operates the probability variation suggestion flag control unit 503 to store the probability variation suggestion flag in the probability variation suggestion flag storage unit 511 (step S601b). This probability change suggestion flag is used for performing the effect during the subsequent variation display of the special symbol in the probability change suggestion effect mode described later after the short hit game is completed.

(Step S602)
As described above, when the special effect for the short hit game is started, the CPU 201a operates the short hit game control means 341 to energize the second winning opening / closing solenoid 928 (step S602), and slides the slide member 921. Let However, in this short win game, the energizing time of the special winning opening second opening / closing solenoid 928 is set to be as short as 0.1 second, so that the slide member 921 returns to the storage position Pk immediately after sliding for a moment. However, due to the fact that friction accompanying the sliding of the slide member 921 acts, the time until the slide member 921 is located at the storage position Pk from the open state is longer than 0.1 seconds.

(Step S603)
In step S602, when the special winning opening second opening / closing solenoid 928 is energized, the time counter provided on the main control board 201 starts measuring time.

(Step S604)
In step S603, when a predetermined time (1.5 seconds) elapses, the CPU 201a activates the short hit game control means 341 and counts and stores “1” in the round number storage means 405. As a result, it is determined how many rounds the short hit game has been played.

(Step S605)
Further, the CPU 201 a operates the short hit game control means 341 to determine the count value stored in the round number storage means 405. If the count value is not 15, the processes in steps S602 to S604 are repeated. Note that the time until the process of step S602 is repeated is the predetermined time (1.5 seconds). That is, in the short hit game, the time during which the slide member 921 is opened is set to 1.5 seconds.

(Step S606)
On the other hand, when the processes in steps S602 to S604 are performed 15 times, the count value stored in the round number storage unit 405 is cleared.

(Step S607)
Further, the CPU 201 a activates the short hit game control means 341, and the subsequent game state is stored in the game state storage means 404. Specifically, when the gaming state becomes the short-time gaming state after completion of the short hit game, a flag indicating that it is in the short-time gaming state is stored in the gaming state storage unit 404. In addition, when the short win game related to the winning of “short win with high probability short time” or “short win without high probability time short” is completed, a flag indicating that the game state storage means 404 is in a high probability game state is displayed. Remembered. On the other hand, when the short win game related to the winning of “short win with normal time” or “short win without normal time” is completed, a flag indicating that the game state is low probability is stored.
In this way, when the process for proceeding with the subsequent game is performed, the control of the short hit game on the main control board 201 is finished.

  On the other hand, in the special symbol variation start process controlled as described above, when the small bonus is won, the “small bonus game” is started after the small bonus special symbol is stopped and displayed. . In the case of winning a small hit, the “small hit game” is controlled as shown in FIG.

(Step S701)
First, at the start of control of the small hit game, the CPU 201 a operates the small hit game control means 345 and transmits a small hit effect start signal to the sub-control board 202. In the sub control board 202, the effect during the small hit game is started by receiving the small hit effect start signal (step S701a). In the present embodiment, a movie is displayed on the symbol display unit 104 during the small hit game, the effect light 111 is lit corresponding to the movie, and music is output from the speaker 277. Such effects are consistently performed from the start to the end of the small hit game, but are controlled by the CPU 202a of the sub control board 202 operating the effect control means 502.

  Note that the time from the start to the end of the small hit game is set in advance, and the effect dedicated to the small hit game is set to the time from the start to the end of the small hit game. Further, the special effect for the small hit game is set to the same content as the special effect for the short hit game. In this way, the player does not know whether the small hit game is being executed or the short hit game is being executed simply by looking at the effect.

  In the sub control board 202, when the small hit effect start signal is received, the CPU 202a operates the probability variation suggestion flag control means 503 to store the probability variation suggestion flag in the probability variation suggestion flag storage means 511 (step S701b).

(Step S702)
As described above, at the same time as the special effect for the small hit game starts, the CPU 201a operates the small hit game control means 345 to turn on the second winning opening / closing solenoid 928 (step S702a). 2 The opening / closing solenoid 928 is energized intermittently. That is, the small hit game control means 345 is programmed to energize the second winning opening / closing solenoid 928 for 0.1 seconds 15 times with an interval of 1.5 seconds. Therefore, when the CPU 201a operates the small hit game control means 345, the opening / closing operation of the slide member 921 is continuously performed 15 times (step S702b).

  This small hit game control method is different from the short hit game control method, but the opening / closing operation of the slide member 921 is set in the same manner for the short hit game and the small hit game. Therefore, not only the production as described above, but also when the opening / closing operation of the slide member 921 is seen, the player makes a distinction between whether a small hit game or a short hit game is being executed. It is not possible.

  Next, the effect control performed during the special symbol variation display will be described with reference to FIG. As described above, when the special symbol variation start process is performed, an effect execution command is transmitted from the main control board 201 to the sub control board 202 (step S412 in FIG. 16). In the present embodiment, when the sub control board 202 receives the effect execution command, the effect related to either the “normal effect mode” or the “probability change suggestion effect mode” is executed.

  Here, the “normal effect mode” is an effect mode mainly performed in the normal game state. Further, the “probability change suggestion effect mode” is an effect mode that is performed after the end of the “small hit game” and the “short hit game”. In the “probable change suggestion effect mode”, for example, in the symbol display unit 104, a character that does not appear in the “normal effect mode” appears, or a different background image is displayed. In addition, an audio production that is different from the “normal production mode” is developed such that music different from the “normal production mode” is output. In any case, the content of the “probable change suggestion effect mode” is not particularly limited as long as it is an effect mode different from the “normal effect mode” at first glance. In this way, by making an effect mode different from the “normal effect mode”, the player is expected to have a high probability game state.

  The ROM 202b of the sub-control board 202 stores two tables, a “normal effect mode table” and a “probability change suggestion effect mode table”. Both tables store a plurality of effect commands having contents corresponding to the respective modes. For example, in the “normal effect mode”, one effect command is selected from the “normal effect mode table”. . In the following, a flow from when an effect command is selected from both tables until the effect is controlled based on the effect command will be described.

(Step S801)
When the sub control board 202 receives the effect execution command, the CPU 202a operates a predetermined program to determine whether or not the probability variation suggestion flag is stored in the probability variation suggestion flag control means 503. Here, the case where the probability variation suggestion flag is stored is a case where either “short win game” or “small hit game” is performed before the special symbol change start processing (FIG. 18). Step S601b, Step S701b of FIG. 19).

(Step S802)
If it is determined in step S801 that the probability variation suggestion flag is not stored, the “normal effect mode table” is selected.

(Step S803)
On the other hand, if it is determined in step S801 that the probability variation suggestion flag storage unit 511 stores the probability variation suggestion flag, the “probability variation suggestion effect mode table” is selected. In other words, after the “short hit game” or the “small hit game” is ended, an effect related to the “probable change suggestion effect mode” is performed during the special symbol variation display.

(Step S804)
As described above, when one of the “normal effect mode table” and the “probable change suggestion effect mode table” is selected, the CPU 202a operates the effect lottery means 501 to perform the effect lottery.

  In addition, in both of the above tables, the table when winning “long win”, the table when winning “short win”, the table when winning “small hit”, and the table when “losing” Each table is provided.
