JP 2010-017446 A

  However, when the variable winning means is provided in the middle of the path through which the game ball is easily guided with respect to the variable winning means, for example, the variable winning means having a short opening pattern with a short opening time can grasp the timing. Thus, it is possible to increase the winning probability to the variable winning means. This becomes a factor that makes it difficult to adjust the specifications of the gaming machine. For this reason, it is desired to make it difficult to make a winning by aiming at a variable winning means constituted only by a short opening pattern or a variable winning means having a higher selection ratio of the short opening pattern than the long opening pattern. Further, for example, when the short opening pattern is selected, in the specification accompanying the transition of the gaming state, if the change of the gaming state is realized by the opening pattern, there is a possibility that the presentation performance may be lowered.

  Therefore, the present invention has a plurality of variable winning means, and makes it difficult to enter one of the variable winning means, and arranges the variable winning means so that the visibility of the open pattern becomes difficult. Thus, it is an object to provide a ball game machine that can facilitate adjustment of specifications and prevent a decrease in the interest of the game.

To achieve the above object, the invention according to claim 1 has special symbol display means (25, 26) for variably displaying a plurality of types of special symbols, and a game ball toward the game board (2). Is a bullet ball game machine (1) for playing a game, wherein the first variable winning means (11, 13) provided on the board surface of the game board and the board surface of the game board are provided. And a second variable winning means (12, 14) configured such that the opening time and / or the number of opening operations is smaller than that of the first variable winning means, and is displayed on the special symbol display means. When the special symbol is a winning special symbol, the first or second variable winning means is selectively opened according to the type of the special symbol, and the ball game machine For guiding a game ball flowing down the board surface of the game board to the first variable winning means 1 ball guiding portion (4a, 4b, 4c), and further includes a second ball guiding portion (4g, 4h) for guiding the game ball flowing down the board surface of the game board to the second variable winning means, The first and second ball guiding units are configured such that the proportion of the game balls led to the second ball guiding unit reaches the second variable winning means, and the game balls led to the first ball guiding unit are the first and second ball guiding units. 1 It is provided so that it may become lower than the ratio which reaches | attains a variable winning means, and it has the normal winning opening (21,22,23) which a game ball can enter, and was arrange | positioned on the board surface of the said game board The winning opening unit (20) further includes a front plate (44) that forms the front surface of the winning port unit, and the second variable winning means is provided behind the front plate . , A ball game machine.

In addition, although the alphanumeric characters in parentheses represent corresponding components in the embodiments described later, the scope of the claims is not intended to be limited to the embodiments. The same applies hereinafter.
According to this configuration, when the first and second variable winning means are compared, the first variable winning means is released when the degree of profit given to the player is relatively high, whereas the second variable winning means is The means are opened at the time of hitting when the degree of profit given to the player is relatively low. Further, the game ball flowing down the board surface of the game board is less likely to be guided to the second variable winning means than the first variable winning means. Therefore, it is difficult to enter the game ball into the second variable winning means that is released only when the degree of profit given to the player is relatively low. As a result, it is possible to increase a sense of expectation for winning with the opening of the first variable winning means, and to prevent a decrease in the interest of the game.
In addition, since the winning opening unit includes a front plate that forms the front of the winning opening unit, and the second variable winning means is provided behind the front plate, the second variable winning means is formed by the front plate. Therefore, it is difficult for the player to see the second variable winning means. As a result, the player cannot accurately grasp the opening / closing timing of the second variable winning means. Thereby, it is possible to effectively prevent the internal state of the ball game machine from being detected based on the opening / closing operation of the second variable winning means.

  As described in claim 2, the first variable winning means includes a first variable winning opening (11) and a first variable winning combination (13) for opening and closing the first variable winning opening. The second variable winning means includes a second variable winning opening (12) and a second variable winning combination (14) for opening and closing the second variable winning opening. The winning combination may be configured so that the opening / closing operation modes thereof are different from each other.

Further, as described in claim 3, wherein the winning opening unit, said has a plurality of ordinary winning holes, the second variable winning device, rather than the usual winning hole of the lowest in the winning opening unit You may arrange | position in the downward position .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a front view of a game board 2 of a ball game machine 1 according to an embodiment of the present invention. The ball game machine 1 includes a game board 2 and a game board holding frame (not shown) for holding the game board 2. A handle (not shown) for adjusting the momentum of a game ball launched from a launching device (not shown) is disposed on the right side of the front lower portion of the game board holding frame. The handle is rotatably held by the game board holding frame. A player can launch a game ball from the launching device toward the game board 2 by gripping and rotating the handle that is rotatably provided in the ball game machine 1, and the rotation of the handle. By adjusting the angle, the momentum of the game ball launched toward the game board 2 can be adjusted. Note that a steel ball having a predetermined diameter (for example, 11.0 mm) is used as the game ball.

  On the board surface of the game board 2, a substantially circular game area S is set at the center. At the periphery of the game area S, there is a substantially arc-shaped guide rail 3A for guiding a game ball launched from the launching device to the upper part (upper left side) of the game board 2, and an inner side extending opposite to the guide rail 3A. A rail 3B is provided. The tip of the inner rail 3B extends to the upper part of the game area S, and the game ball launched by the launching device is guided between the guide rail 3A and the inner rail 3B to the upper part of the game area S. In the game area S, a number of obstacle nails 4 (not shown) are implanted. In addition, a windmill accessory 91 provided rotatably around a rotation axis extending in the front-rear direction is disposed slightly below the center of the left portion of the game area S.

  A center unit (not shown) including a liquid crystal display unit 16 as an example of a production device is disposed in the center of the game board 2 (FIG. 1 shows a state in which the center unit is removed, and a liquid crystal display Unit 16 is indicated by a two-dot chain line). The liquid crystal display unit 16 is for displaying a production symbol or a predetermined message that is stopped or changed during the game of the ball game machine 1. The periphery of the liquid crystal display unit 16 is surrounded by a frame (not shown). A decorative member 5 is attached to the front surface of the frame so as to surround the liquid crystal display unit 16. The peripheral edge 5A from the upper part to the right part of the decorative member 5 is formed in an arc shape having a slightly smaller diameter than the radius of the game area S with the center of the circular game area S as the center. In the upper part of the game area S, an arc-shaped sphere upstream passage 17 defined by the guide rail 3A and the peripheral edge 5A of the decorative member 5 is formed. The ball upstream passage 17 has a predetermined width larger than the diameter of the game ball with respect to the entire region in the longitudinal direction. The left end edge of the sphere upstream passage 17 is open leftward and downward at a position that is slightly diagonally above and to the right of the front end (upper end) of the inner rail 3B. Further, the lower edge of the ball upstream passage 17 opens downward to the right of the game area S. Therefore, the ball upstream passage 17 can guide the game ball released from the upper left part of the game area S toward the upper right along the guide rail 3A and the inner rail 3B to the right part of the game area S. It is like that.

  In the lower part of the game area S, a first special symbol start port 6 and a second special symbol start port 7 are arranged vertically. The first special symbol start port 6 and the second special symbol start port 7 are provided so that game balls flowing down along the surface of the game board 2 can enter. The incoming ball accessory 9 that defines the first special symbol start port 6 and the incoming ball accessory 10 that defines the second special symbol start port 7 are juxtaposed in the vertical direction. The second special symbol starting port 7 is provided with an electric tulip accessory 8, whereas the first special symbol starting port 6 is a non-actuated winning port having no opening and closing means.

  In the game board 2, an electric tulip accessory 8 including a pair of blades 8 </ b> A is disposed in association with the second special symbol starting port 7. The electric tulip accessory 8 is usually constricted in a state where the tip portions of the blades 8A are close to each other (hereinafter referred to as “stenosis state”). In the game area S, a pitching accessory 9 that divides the first special symbol starting port 6 is arranged immediately above the space formed between the electric tulip actors 8 in the narrowed state of each blade 8A. In other words, in the constricted state of the electric tulip accessory 8, the game ball flowing down along the board surface of the game board 2 enters the second special symbol start opening 7, and the entrance bonus of the first special symbol start opening 6 9 prevents the second special symbol starting port 7 from being closed.

  Then, when the tip of each blade 8A of the electric tulip accessory 8 as shown in FIG. 1 is expanded from the narrowed state so as to be separated from each other, the ball accessory 9 of the first special symbol start opening 6 A passage (not shown) toward the second special symbol start port 7 is formed on both the left and right sides, and a game ball can enter the second special symbol start port 7 through this passage. Therefore, if the electric tulip accessory 8 is in the constricted state, there is almost no game ball entering the second special symbol starting port 7, but the electric tulip accessory 8 is expanded (hereinafter referred to as “expanded state”). The game ball enters the second special symbol starting port 7 with a relatively high probability.

The configuration of the electric tulip accessory 8 is not limited to this. For example, the electric tulip accessory 8 may be configured to move back and forth in the front-rear direction, or the first variable winning combination 13 or the second variable winning described below. Similarly to the accessory 14 (see FIG. 5, FIG. 6A and FIG. 6B), it may be configured to tilt to the near side about the swing axis.
When a game ball enters the first special symbol start port 6 or the second special symbol start port 7, a predetermined number (for example, three balls for the game ball entering the first special symbol start port 6 and second For example, 5 winning balls are paid out from the winning ball payout device 50 (see FIG. 9) for a game ball entering the special symbol starting port 7. In addition, a big hit lottery for determining whether or not to execute the special profit state is executed in accordance with the game ball entering the first special symbol start port 6 or the second special symbol start port 7.

  As shown in FIG. 1, for example, a first variable winning opening 11 having a rectangular shape in a long plan view on the left and right is disposed on the right side of the second special symbol starting port 7 (lower right portion of the game area S). Yes. The first variable winning opening 11 is formed in a size that allows a plurality of (for example, 3 to 4) game balls to enter simultaneously in the left-right direction. In relation to the first variable winning opening 11, a first variable winning combination 13 capable of opening and closing the first variable winning opening 11 is provided. The first variable winning slot 11 and the first variable winning combination 13 constitute a first variable winning means. While the first variable winning combination 13 can block the first variable winning opening 11 in a state along the surface of the game board 2 and prevent the game ball from entering the first variable winning opening 11, From this state, the first variable prize opening 11 is opened by tilting forward about a swing shaft (not shown) arranged along the lower edge of the first variable prize opening 11 to open the first variable prize opening 11. A game ball flowing down on the winning opening 11 can be introduced into the first variable winning opening 11. When a game ball enters the first variable winning opening 11, a predetermined number (for example, 10 balls for the game ball entering the first variable winning opening 11) is paid out from the winning ball payout device 50. It is.

A normal symbol gate 15 through which a game ball flowing down along the board surface of the game board 2 can pass is disposed immediately above the first variable prize winning opening 11. The normal symbol gate 15 is disposed above (ie, directly above) the upper edge of the first variable winning opening 11 and spaced apart by about one game ball, and the central position of the first variable winning opening 11 in the left-right direction. It is arranged slightly more to the right.
When the game ball passes through the normal symbol gate 15, the normal symbol lottery (ordinary for determining whether to open the second special symbol start opening 7 (whether the electric tulip accessory 8 is in the expanded state)) Profit status lottery) is executed. The probability determined that the second special symbol start port 7 is opened by the normal symbol lottery (the winning probability of the normal symbol lottery) is, for example, 1/100 at the time of non-execution of the probability variation game described later, and during the probability variation game described later. For example, 1/1.

  A stage 18 is disposed directly below the first variable prize winning port 11. The stage 18 has an upper surface 19 formed of a gently inclined flat surface that goes downward as it goes to the left, and guides a game ball that has dropped onto the upper surface 19 of the stage 18 toward the left side so as to be visible. The stage 18 is substantially aligned with the first variable winning opening 11 in the left-right direction, the right end 19B of the upper surface 19 of the stage 18 is located immediately below the right end of the first variable winning opening 11, and the left end 19A of the upper surface 19 of the stage 18 is. Is located slightly to the left of the first variable winning opening 11 directly below the left end.

  In the lower left part of the game board 2, a first normal winning port 21, a second normal winning port 22, and a third normal winning port 23 are provided so as to be aligned in a diagonally downward line. When a game ball wins each of the normal winning ports 21, 22, 23, a predetermined number (for example, three balls) of winning balls are paid out from the winning ball payout device 50 (see FIG. 9). These three normal winning ports 21, 22, and 23 are unitized to form a side lamp unit (normal winning port unit) 20 having three normal winning ports. Further, the side lamp unit 20 further has a second variable prize opening (see FIGS. 6A and 6B) 12. The second variable winning opening 12 is disposed in the lower right part of the inside of the side lamp unit 20, and is disposed at a lower position in the vertical direction than the lowest third ordinary winning opening 23. Further, the side lamp unit 20 is provided with a second variable winning combination 14 (see FIGS. 5, 6A, and 6B) that can open and close the second variable winning opening 12. The second variable winning opening 12 and the second variable winning combination 14 constitute a second variable winning means. As will be described later, the second variable winning combination 14 is a pointed blade in plan view that can swing around a blade shaft (swing shaft) 55 (see FIGS. 5, 6A, and 6B) extending in the front-rear direction. It is comprised by the member 59 (refer FIG. 5, FIG. 6A and FIG. 6B).

In other words, the first variable prize opening 11 is arranged to the right of the center of the board surface of the game board 2 in the left-right direction, whereas the second variable prize opening 12 is the center of the board surface of the game board 2. It is arranged on the left side.
Further, both the first and second variable prize winning openings 11 and 12 are arranged below the center of the board surface of the game board 2 in the vertical direction. From another point of view, both the first and second variable prize winning openings 11 and 12 are arranged below the lower end of the liquid crystal display unit 16 arranged at the center of the board surface of the game board 2. .

  A game ball launched from a launching device (not shown) by a player's handle operation at an appropriate momentum is directed diagonally upward to the right from the upper left portion of the game area S (along the guide rail 3A and the inner rail 3B). Let go. The game ball released from the upper left part of the board surface of the game board 2 flows down between the obstacle nails 4 implanted in the left half (left part and lower left part) of the game area S. In addition, some of the game balls collide with the windmill accessory 91, collide with the windmill accessory 91 provided to be rotatable around a predetermined rotation axis, and rotate the windmill accessory 91. The collided sphere is distributed to the left side or the right side of the windmill accessory 91. Thereafter, it flows down between the obstacle nails 4. Thereby, the game ball can be guided to the first or second special symbol starting port 6, 7, the first, second or third normal winning port 21, 22, 23 or the second variable winning port 12. .

  In addition, the bullet ball game machine 1 can perform a so-called right-handed game (a game in which a game ball is launched toward the right half of the game area S). Specifically, when the rotation angle of the handle is the maximum angle, the game ball is launched with a very strong momentum. Then, from the upper left part of the game area S toward the upper right side (along the guide rail 3A and the inner rail 3B), the game ball is released with great force. The game ball released from the upper left part of the game area S passes through the ball upstream passage 17 to reach the right part of the game area S and is released downward in the right part. The game ball released downward is guided to the first or second special symbol start port 6, 7 or the first variable winning port 11 by the obstacle nail 4 planted in the right part of the game board 2. Is possible.

Of the game balls flowing down along the board surface of the game board 2, the first or second special symbol start port 6, 7, the first or second variable winning port 11, 12, or the first, second or third normal A game ball (out ball) that has not entered any of the winning holes 23 enters the machine from the out port 24 formed in the lower part of the game area S and is collected by a ball collection unit (not shown).
In the upper right corner of the outer area of the guide rail 3A on the board surface of the game board 2, the first special symbol display means 25, the second special symbol display means 26, the special symbol hold display means 27, the normal symbol display means 28 and the normal symbol display means 28 A symbol hold display means 29 is provided.

  The first special symbol display means 25 is constituted by a seven-segment display or the like capable of variably displaying (variably displaying) one or a plurality of (for example, one) special symbols. The first special symbol display means 25 displays the first special symbol fluctuating for a predetermined time on the condition that a game ball enters the first special symbol start port 6, and at the time of entering the first special symbol start port 6 When the acquired jackpot determination random number value coincides with a predetermined jackpot determination value, it stops in a predetermined jackpot mode, and in other cases it stops in a disengagement mode. For example, when 10 kinds of numerical symbols “0” to “9” and a symbol symbol “−” are used for the first special symbol, “0” to “9” are big hits, and “−” is off. May be set.

  The second special symbol display means 26 is constituted by a seven-segment display or the like capable of variably displaying (variably displaying) one or a plurality of (for example, one) special symbols. The second special symbol display means 26 displays the second special symbol fluctuating for a predetermined time on the condition that a game ball enters the second special symbol start opening 7, and when entering the second special symbol start opening 7 When the acquired jackpot determination random number value coincides with a predetermined jackpot determination value, it stops in a predetermined jackpot mode, and in other cases it stops in a disengagement mode. For example, when 10 kinds of numerical symbols “0” to “9” and a symbol symbol “−” are used for the second special symbol, “0” to “9” are big hits, and “−” is not good. May be set. It should be noted that the first and second special symbols need only have identification information that can be identified by the player, and do not necessarily have a meaning like a numeric symbol.

  When a game ball enters the first special symbol start port 6 during the symbol changing operation or the special profit state in the first and second special symbol display means 25, 26, the first special symbol display for the entered ball The symbol changing operation of the means 25 can be held up to the maximum number of holds (for example, 4). Further, when a game ball enters the second special symbol start port 7 during the symbol changing operation of the first and second special symbol display means 25, 26 or in the special profit state, the second special symbol for the incoming ball is entered. The symbol change operation of the symbol display means 26 can be held up to the maximum number of holds (for example, 4).

  The symbol variation operation of the first special symbol display means 25 being held is finished and the symbol variation operation of the first special symbol display means 25 or the second special symbol display means 26 being executed is finished and is suspended. After all the symbol variation operations of the second special symbol display means 26 are completed, the second special symbol display means 26 is executed according to the suspended order. In addition, the suspended symbol variation operation of the second special symbol display means 26 is suspended after the execution of the symbol variation operation of the first special symbol display means 25 or the second special symbol display means 26 being executed. Executed according to the order. That is, in the ball game machine 1, when both the number of reserved symbol variation actions of the first and second special symbol display means 25 and 26 are 1 or more, the symbol variation operation of the first special symbol display means 25 is more than that. The second special symbol display means 26 is configured to give priority to symbol variation.

The special symbol hold display means 27 displays the number of reserved balls of the first special symbol according to the number of display of the first symbol (not shown), and holds the ball of the second special symbol according to the display number of the second symbol (not shown). Display a number.
The normal symbol display means 28 is for variably displaying the normal symbol (variable display), and is provided so as to be as inconspicuous as possible by using a 7-segment display or the like. If the normal symbol is displayed in a variable manner for a predetermined time on the condition that it passes, the hit determination random number value obtained when the game ball passes through the normal symbol gate 15 matches a predetermined hit determination value. In the aspect, when they do not match, the operation is stopped in a predetermined off-state. It is desirable that a symbol having no special meaning is assigned to the normal symbol so that the player cannot easily distinguish the type.

  When the game ball passes through the normal symbol gate 15 during the symbol changing operation of the normal symbol display means 28 or the expanding operation of the electric tulip accessory 8, the symbol of the normal symbol display means 28 for the passage of the game ball. Fluctuating operation can be held up to the maximum number of holds (for example, 4). The symbol variation operation of the normal symbol display means 28 being held is executed in accordance with the order in which the symbol variation operation of the normal symbol display means 28 being executed has been completed.

The result of the big hit lottery is displayed not only on the special symbol display means 25 and 26 but also on the liquid crystal display unit 16. In the display screen of the liquid crystal display unit 16, three symbol display positions are set in a line in the left-right direction, and one effect symbol corresponding to each symbol display position, for example, a total of three effect symbols. It can be displayed in a variable manner together with the effect image.
At the same time that the first special symbol display means 25 starts to change the first special symbol on the condition that the game ball enters the first special symbol start port 6, the effect symbol starts to change according to a predetermined fluctuation pattern. The effect symbols are stopped in a predetermined order such as left → right → middle with the first special symbol being stopped. In addition, on the condition that a game ball enters the second special symbol start port 7, the effect symbol is started to vary according to a predetermined variation pattern simultaneously with the start of variation of the second special symbol in the second special symbol display means 26. At the same time, the effect symbols are stopped in a predetermined order, such as left → right → middle. When the result of the big hit lottery is a big hit, after the effect symbol changing operation is finished, the combination of the big hit effect symbols is stopped and displayed on the liquid crystal display unit 16. On the other hand, when the result of the big hit lottery is lost, the combination of the effect symbols for losing is stopped and displayed on the liquid crystal display unit 16 after the effect symbol changing operation is finished.

  During the special profit state, the first variable winning opening 11 is opened by the swing of the first variable winning combination 13, or the second variable winning opening 12 is opened by the swing of the second variable winning combination 14. Is done. The bullet ball game machine 1 is provided with two types of special profit states, a first special profit state in which the first variable winning opening 11 is opened and a second special profit state in which the second variable winning opening 12 is opened. The first and second special profit states will be described later.

Thus, the special symbol displayed on the special symbol display means 25 and 26 is displayed, and the first and second variable winning prize ports 11 and 12 are selectively opened according to the type of the special symbol. In other words, it can be paraphrased.
The ball game machine 1 is provided with a probability variation game. The winning probability of the big win lottery when the probability variation game is not executed (a relatively advantageous mode) is set to 1/200, for example. On the other hand, the winning probability of the jackpot probability during the probability variation game (relatively disadvantageous mode) is set to 1/50, for example.

  In addition, a support game is prepared for the ball game machine 1. When the support game is not executed, the symbol change time of the normal symbol display means 28 with respect to the passage of the game ball to the normal symbol gate 15 is, for example, 30 seconds, and the winning probability of the normal symbol lottery is, for example, 1/100. The number of times of opening the second special symbol start opening 7 (expansion of the electric tulip accessory 8) at the time of winning the lottery is, for example, one.

On the other hand, during the execution of the support game, the symbol variation time of the normal symbol display means 28 for the passage of the game ball to the normal symbol gate 15 is, for example, 3.0 seconds, and the winning probability of the normal symbol lottery is, for example, 1/1. 1 and the number of times of opening the second special symbol start opening 7 (expanding the electric tulip accessory 8) at the time of winning the normal symbol lottery is, for example, two.
As the probability variation game prepared in the ball game machine 1, a probability variation game with a support game to which a support game is given simultaneously with the execution of the probability variation game, and a support game in connection with the execution of the probability variation game are provided. There is a stochastic game with no support game. When the support game is not executed, the electric tulip role 8 rarely expands, so the game ball flowing down rarely enters the second special symbol starting port 7, but when the support game is executed, the electric tulip role The probability that the object 8 is frequently expanded and enters the second special symbol start port 7 is high.

  The side lamp unit 20 is disposed along the inner side of the inner rail 3B in the lower left portion of the game area S. The side lamp unit 20 is detachably fitted from the front side into a side lamp unit mounting hole (not shown) formed corresponding to a portion along the inner side of the inner rail 3B on the plywood constituting the game board 2. And fixed to the game board 2 with screws or the like. The back surface of the side lamp unit 20 is exposed on the back side of the game board 2.

Further, a rectangular second variable winning hole outlet hole 64 (see FIG. 3) is formed in the back plate 49 at a position corresponding to the second variable winning hole inlet hole 38A. The rear of the outflow hole 64 for the second variable prize winning opening is not covered with anything.
As shown in FIGS. 2 to 4, the first normal winning opening 21 is defined by the first normal winning combination 21 </ b> A and the front surface of the base plate 30. The first normal winning combination 21 </ b> A guides the game ball that has entered the first normal winning opening 21 backward and allows it to flow into the first inflow hole 41. The game ball that has entered the first inflow hole 41 passes through the first guide passage 46, reaches the first outflow hole 51, and then flows down through the first downflow passage 61. Then, after being detected by the first winning detection switch 71, it is collected by the ball collecting unit.

  Further, the second normal winning combination 22 is defined by the second normal winning combination 22 </ b> A and the front surface of the base plate 30. The second normal winning combination 22 </ b> A guides the game ball that has entered the second normal winning opening 22 backward and flows into the second inflow hole 42. The game balls that have entered the second inflow hole 42 join the second guide passage 48 through the junction passage 47 and then flow through the second guide passage 48.

The game ball that has entered the third inflow hole 43 reaches the second outflow hole 53 through the second guide passage 48 and then flows down through the second downflow passage 63. Then, after being detected by the second winning detection switch 73, it is collected by the ball collecting unit.

FIG. 5 is a perspective view showing a configuration around the second variable winning combination 14.
The second variable winning combination 14 has an axial shape extending in the front-rear direction, a blade shaft 55 that can rotate around the shaft, and a blade member 59 that is fixed to the blade shaft 55 and can rotate around the blade shaft 55. And. The base end portion of the blade member 59 has a substantially cylindrical shape, and the front end portion of the blade shaft 55 is fitted and fixed in the base end portion. The blade member 59 has a predetermined front-rear width, has a frontal triangular shape, and has a left surface (first guide surface) 59A and a right surface (second guide surface) 59B each formed of a flat surface. The front shape of the blade member 59 is an acute triangle with the inner angle of the tip portion as the apex angle, and the inner angle of the tip portion is the smallest inner angle. More specifically, the cross-sectional shape orthogonal to the blade shaft 55 forms an isosceles triangle with the inner angle of the tip of the blade member 59 as the apex angle.

  The solenoid holder 35 has a box shape whose front is open. The solenoid 54 has a plunger 69 that protrudes forward from its main body in a shaft shape and is movable in the vertical direction. The tip of the plunger 69 is connected to the blade shaft 55 via the link mechanism 90. When the plunger 69 moves up and down by driving the solenoid 54, the blade shaft 55 rotates around its axis, and the blade member 59 rotates around the blade shaft 55 along with the rotation of the blade shaft 55.

6A and 6B are front views showing a state in which only the decorative plate 44 of the decorative cover 32 is removed from the side lamp unit 20. The configuration of the side lamp unit 20 will be described with reference to FIGS. 6A and 6.
The interval between the decorative plate 44 of the decorative cover 32 and the base plate 30 is set to be larger than the diameter of the game ball. Therefore, the game ball can pass through the ball circulation space 58, and the narrow ball circulation space 58 is defined by the decoration plate 44 and the base plate 30 of the decoration cover 32.

  As described above, no wall is provided between the upper wall 45C and the first ordinary winning combination 21A, and no wall is provided between the first ordinary winning combination 21A and the second ordinary winning combination 22A. Is not provided, and no wall is provided between the third normal winning combination 23A and the right side wall 40B described below. Therefore, first, second, and third upper openings 76, 77, and 78 (see FIG. 2) are formed between the decorative plate 44 of the decorative cover 32 and the base plate 30 in the upper portion thereof. In other words, the first upper opening 76 is defined between the decorative plate 44 and the base plate 30 by the upper wall 45C and the left side wall of the first ordinary prize-winning item 21A. Further, a second upper opening 77 is defined between the decorative plate 44 and the base plate 30 by the right side wall of the first normal prize winning combination 21A and the left side wall of the second normal prize winning combination 22A. Further, a third upper opening 78 is defined between the decorative plate 44 and the base plate 30 between the right side wall of the third ordinary prize winning combination 23A and the right side wall 40B described below.

Further, the space 65 formed between the lower end of the right peripheral wall 40 and the right end of the upper left peripheral wall 45 circulates in the ball distribution space 58 on the lower surface of the ball distribution space 58 (the surface facing the game area S). A lower opening 80 (see FIG. 3) for guiding a game ball to be played toward the out port 24 (out side) is formed.
The right peripheral wall 40 includes a right side wall 40B extending up and down along the right side of the decorative plate 44, and a guide wall that extends obliquely from the upper right end of the decorative plate 44 (see FIGS. 2 and 4) of the decorative case 32 toward the lower left. 70 and a second variable winning prize compartment partitioning accessory 72 continuous with the lower end of the guide wall 70 are integrally provided. The guide wall 70 has a flat inclined surface (wall surface) 67 that is flat toward the left as it goes downward. The upper end (right end) of the right peripheral wall 40 is connected to the upper end of the right side wall 40B.

  The second variable winning opening section 72 forms a second variable winning opening 12 that is gently curved and extends downward as it goes downward. The second variable winning opening 12 has a long flow path, and at the same time, the flow path width is set such that only one game ball can enter. The second variable winning port partitioning feature 72 is continuous with the lower end of the guide wall 70 and guides the game ball toward the second variable winning port inflow hole 38A, and a second variable winning component. A receiving member 75 for enclosing both sides and the lower side of the mouth inflow hole 38A, and a switch attachment provided between the partition member 74 and the receiving member 75 and capable of holding the second variable winning opening winning detection switch 60 The unit 79 is integrally provided. The curved partition member 74 is formed such that it goes downward as it goes to the right side, and its inclination gradient increases as it goes to the right side. The receiving member 75 is substantially U-shaped in plan view and has a predetermined width in the front-rear direction. On the inner peripheral surface of the bottom portion of the receiving member 75, a rib 84 is formed for guiding the game ball that has entered the second variable winning port inflow hole 38A backward.

  At the right end of the ball circulation space 58, there is a guide flow passage 95 that is partitioned by the inclined surface 67 of the guide wall 70 and the third normal winning combination 23 and extends substantially linearly in the left direction as it goes downward. Is provided. The guide flow passage 95 has a third upper opening 78 at the upper end. The second variable prize-winning port 12 branches off from the middle of the flow direction of the guide flow path 95, and the blade shaft 55 of the second variable prize-winning accessory 14 is provided below the branch part 95A (inlet part). It is arranged. The blade member 59 is in a closed state in which the second variable winning opening 12 is closed in a posture that is substantially orthogonal to the longitudinal direction of the second variable winning opening 12 (hereinafter referred to as a “closed posture” (first posture)). The second variable winning opening 12 is opened in a posture (hereinafter referred to as “open posture” (second posture)) substantially along the longitudinal direction of the long second variable winning opening 12. When the blade member 59 is in the closed posture, the left surface 59A of the blade member 59 is included in the same plane as the inclined surface 67 of the guide wall 70 (the blade member 59 is retracted from the guide flow passage 95). On the other hand, when the blade member 59 is in the open posture, the tip of the blade member 59 protrudes to the left of the extended surface 67A (shown by a broken line in FIG. 6B) of the inclined surface 67 of the guide wall 70 and enters the guide flow passage 95. Overhang. In this state, the right surface 59B of the blade member 59 is orthogonal to the inclined surface 67 of the guide wall 70 (specifically, the angle formed by the right surface 59B of the blade member 59 and the inclined surface 67 of the guide wall 70 is, for example, 95 °). In addition, the protrusion length D (see FIG. 6B) of the blade member 59 with respect to the guide flow passage 95 at this time is set to be shorter than the diameter of the game ball and longer than the radius of the game ball. Yes.

In the state in which the blade member 59 is in the closed position, only a small gap much smaller than the diameter of the game ball is formed between the blade member 59 and the second variable winning hole partitioning accessory 72. A game ball that circulates on the path 95 does not enter the second variable winning opening 12.
In addition, since the left surface 59A of the blade member 59 is included in the same plane as the inclined surface 67 of the guide wall 70 in a state where the blade member 59 is in the closed posture, the blade member 59 flows down along the guide wall 70. Can be smoothly guided to the out side.

  On the other hand, in a state where the blade member 59 is in the open posture, the angle formed by the right surface 59B of the blade member 59 and the inclined surface 67 of the guide wall 70 is 95 °. Since the protrusion length D (see FIG. 6B) of the blade member 59 at this time is shorter than the diameter of the game ball, the game ball flowing through the guide flow passage 95 is reliably guided to the second variable winning opening 12 by the blade member 59. Instead, some of the game balls will be guided out beyond the blade member 59. Further, since the protruding length D of the blade member 59 (see FIG. 6B) is longer than the radius of the game ball, when the game ball collides with the blade member 59 in the open posture, the center (center of gravity) of the game ball ) Is located on the blade member 59.

  Accordingly, the game ball flowing down the guide flow passage 95 may collide with the blade member 59 protruding into the guide flow passage 95 and bounce off the blade member 59 and enter the second variable winning opening 12. Of course, it is needless to say that there is a sufficient possibility that a game ball flowing down the guide flow path 95 directly enters the second variable winning opening 12. Thereby, it is possible to sufficiently ensure the possibility of entering the second variable winning a prize opening 12.

The game balls that have entered the second variable winning opening 12 are guided toward the second variable winning opening inflow hole 38 </ b> A by the second variable winning opening section 72. The game ball that has reached the inflow hole 38A for the second variable prize winning opening is then freely dropped and collected by the ball collection unit.
That is, in the ball game machine 1, in order to enter the second variable prize opening 12, it is necessary to enter the game ball into the third upper opening 78, and the game ball passes through the guide flow passage 95. It is necessary to open the second variable winning combination 14 during the distribution.

  FIG. 7 is an enlarged front view showing a peripheral portion of the first variable winning award slot 11 on the board surface of the game board 2. As described above, a large number of obstacle nails 4 are planted on the surface of the game board 2. In the lower right portion of the game area S, the obstacle nails 4 that become the road nails 4P along the lower edge 5B of the decorative member 5 are arranged in a line in a substantially right upward direction. Most of the many obstacle nails 4 constituting the road nail 4P are arranged with an interval through which the adjacent obstacle nail 4 and the game ball cannot pass.

  A pair of first obstruction nails 4a, 4a are arranged in a downward-sloping manner above the right end portion of the first variable winning opening 11 (to the right of the normal symbol gate 15). That is, the line segment connecting the pair of first obstacle nails 4a, 4a (the opening surface of the guide port defined by the obstacle nails 4a) is inclined with respect to the horizontal horizontal plane. The pair of first obstacle nails 4a, 4a is provided with an interval through which one game ball can pass. The game ball that has passed between the pair of first obstacle nails 4a, 4a is easily guided to the first variable winning opening 11 (passes through the front area of the first variable winning opening 11).

  A pair of second obstruction nails 4b, 4b are arranged in a line to the lower right above the central portion in the left-right direction of the first variable winning opening 11 (upper left of the normal symbol gate 15). That is, the line segment connecting the pair of second obstacle nails 4b, 4b (the opening surface of the guide port defined by the obstacle nail 4b) is inclined with respect to the horizontal horizontal plane. The pair of second obstacle nails 4b, 4b are provided with an interval through which one game ball can pass. The game ball that has passed between the pair of second obstacle nails 4b, 4b is easily guided to the first variable winning opening 11 (passes through the front area of the first variable winning opening 11).

  A pair of third obstacle nails 4c, 4c are arranged side by side right above the normal symbol gate 15. Therefore, a line segment connecting the pair of third obstacle nails 4c, 4c (opening surface of the guide port defined by the obstacle nail 4c) is hardly inclined with respect to the horizontal horizontal plane. The pair of third obstacle nails 4c, 4c is provided with an interval through which one game ball can pass, and the game balls that have passed between the third obstacle nails 4c, 4c are normally guided to the symbol gate 15. Is done. In addition, since the normal symbol gate 15 is located immediately above the first variable winning port 11 and is arranged slightly to the right of the center of the first variable winning port 11 in the left-right direction, the game that has passed through the normal symbol gate 15 The ball is always guided to the first variable winning opening 11 (passes through the front area of the first variable winning opening 11).

  A pair of fourth obstacle nails 4d, 4d are arranged on the right side of the normal symbol gate 15 so as to be lined up to the right. Therefore, the line segment connecting the pair of fourth obstacle nails 4d, 4d (the opening surface of the guide port defined by the obstacle nail 4d) is inclined with respect to the horizontal horizontal plane. The pair of fourth obstacle nails 4d, 4d are provided with an interval through which one game ball can pass. Between the pair of fourth obstacle nails 4d, 4d is located to the right of the first obstacle nails 4a, 4a, not above the first variable winning opening 11, and the fourth obstacle nails 4d, 4d. The other obstacle nail 4 is not arranged below the space. Therefore, the game ball that has passed between the pair of fourth obstacle nails 4d, 4d is not guided to the first variable winning port 11 but is guided to the out side (out port 24).

  A pair of fifth obstacle nails 4e, 4e are arranged side by side on the upper right side of the normal symbol gate 15. The pair of fifth obstacle nails 4e, 4e is provided with an interval through which one game ball can pass. Between the pair of fifth obstacle nails 4e, 4e is not positioned above the first variable winning opening 11, and no other obstacle nail 4 is arranged below the fifth obstacle nails 4e, 4e. Therefore, the game ball that has passed between the pair of fifth obstacle nails 4e, 4e is not guided to the first variable winning opening 11, but is guided to the out side (out opening 24). In other words, the first out guide port is defined by the pair of fourth obstacle nails 4d and the pair of fifth obstacle nails 4e.

  With reference to FIG. 7, a distribution path of game balls that can be entered into the first variable winning opening 11 is examined. The game ball released downward from the right part of the game area S exclusively through the ball upstream passage 17 is guided by the obstacle nail 4 planted in the lower right part of the game area S and flows down. Are guided to the first variable winning opening 11. At this time, if the first variable winning opening 11 is in an open state, the guided game ball enters the first variable winning opening 11.

  The obstacle nail that is planted above the first variable winning opening 11 with an interval through which the game ball can pass is only one of the first obstacle nail 4a, the second obstacle nail 4b, and the third obstacle nail 4c. Absent. Therefore, the game balls guided to the first variable winning opening 11 are between the pair of first obstacle nails 4a, 4a, between the pair of second obstacle nails 4b, 4b, and the pair of first obstacle nails 4c. , 4c, the game ball is guided to the first variable winning opening 11 after passing through any of the above. In other words, the first guide port is defined by the pair of first obstacle nails 4a, the pair of second obstacle nails 4b, and the pair of third obstacle nails 4c.

  By the way, since the stage 18 disposed immediately below the first variable prize opening 11 is substantially aligned with the first variable prize opening 11 in the left-right direction, the first variable prize opening 11 is in a closed state (the first variable prize winning opening 11). When the accessory 13 is in the closed state), the game ball passes through the front of the first variable winning opening 11, reaches the upper surface 19 of the stage 18, and then rolls on the upper surface 19 of the stage 18.

  On the left side of the stage 18, a pair of guide nails 4 f and 4 f are arranged side by side on the left and right (slightly upward). The pair of guide nails 4f and 4f are disposed so as to be positioned substantially on an extension line of the upper surface 19 of the stage 18. The pair of guide nails 4f and 4f are spaced apart from each other so that the game balls cannot pass therethrough. On the extended line connecting the left end 19A of the upper surface 19 and the pair of guide nails 4f, 4f, the second special symbol starting port 7 (the electric tulip accessory 8 is in the expanded state) in the open state is located. Therefore, when the first variable winning opening 11 is closed, the game ball guided to the first variable winning opening 11 passes through the front of the first variable winning opening 11 and reaches the upper surface 19 of the stage 18. The upper surface 19 of the stage 18 guides the second special symbol starting port 7 in the open state.

  FIG. 8 is an enlarged front view showing a peripheral portion of the second variable winning opening 12 on the surface of the game board 2. In the lower left portion of the game area S, the obstacle nails 4 that become the road nails 4Q are arranged substantially in a row in the lower right direction along the lower edge 5B of the decorative member 5. Below the road nail 4Q, the first obstacle nail row 4R extending in parallel with the road nail 4Q is arranged in a line substantially downwardly to the right. Below the first obstacle nail row 4R, the second obstacle nail row 4S extending in parallel with the road nail 4Q is arranged substantially in a row downwardly to the right.

The pair of sixth obstacle nails 4g, 4g are provided with an interval through which one game ball can pass. Since no other obstacle nail 4 is disposed below the pair of sixth obstacle nails 4g, 4g, the game ball that has passed between the pair of sixth obstacle nails 4g, 4g has a third upper opening 78. It is easy to be guided to. A game ball flowing on the second obstacle nail row 4S (the bottom bold arrow shown in FIG. 8) is guided to the sixth obstacle nail 4g.

  On the upper right side of the third upper opening 78, a pair of seventh obstacle nails 4h, 4h are arranged side by side to the lower right.

The space between the pair of seventh obstacle nails 4h, 4h is positioned higher than that between the sixth obstacle nails 4g, 4g in the vertical direction. The pair of seventh obstacle nails 4h, 4h are provided with an interval through which one game ball can pass. Since no other obstacle nail 4 is disposed between the third upper opening 78 below the pair of seventh obstacle nails 4h, 4h, it passes between the pair of seventh obstacle nails 4h, 4h. The game ball is easily guided to the third upper opening 78. The seventh obstacle nail 4h includes a game ball flowing on the road nail 4Q (the uppermost bold arrow shown in FIG. 8) or the first obstacle nail row 4R (the bold arrow in the middle in the vertical direction shown in FIG. 8).

The pair of eighth obstacle nails 4j, 4j is provided with an interval through which one game ball can pass. Since the eighth obstacle nail 4j, 4j is disposed close to the first upper opening 76, and no other obstacle nail 4 is disposed between the eighth obstacle nail 4j, 4j and the first upper opening 76, The game ball that has passed between the pair of eighth obstacle nails 4j, 4j is guided to the first upper opening 76. Since the game ball that has flowed into the first upper opening 76 is guided to the out side (out port 24) and is not guided to the guide flow passage 95, a gap between the pair of eighth obstacle nails 4j and 4j is provided. The game ball that has passed is not guided to the second variable winning opening 12.

  A pair of ninth obstacle nails 4k, 4k are arranged in a right-downward direction at the upper left of the second upper opening 77, that is, at the entrance of the second upper opening 77.

Since the game ball that has flowed into the second upper opening 77 is guided to the out side and is not guided to the guide flow passage 95, the game ball that has passed between the pair of ninth obstacle nails 4k, 4k There is no guidance to the second variable winning opening 12.

  A pair of tenth obstacle nails 4m and 4m are arranged side by side right above the first ordinary winning opening 21, that is, at the entrance of the first ordinary winning opening 21. The pair of tenth obstacle nails 4m, 4m are provided with an interval through which one game ball can pass. The tenth obstacle nail 4m, 4m is arranged immediately above the first ordinary winning opening 21, and another obstacle nail 4 is arranged between the tenth obstacle nail 4m, 4m and the first ordinary winning opening 21. Therefore, the game ball that has passed between the pair of tenth obstacle nails 4m, 4m is guided to the first normal winning opening 21. Since the game balls that have flowed into the first normal winning opening 21 are collected as described above, the gaming balls that have passed between the pair of tenth obstacle nails 4m, 4m are guided to the second variable winning opening 12. Absent.

  A pair of eleventh obstacle nails 4n, 4n are arranged side by side right above the second ordinary winning opening 22, that is, at the entrance of the second ordinary winning opening 22.

The pair of twelfth obstacle nails 4o, 4o are provided with an interval through which one game ball can pass. The 12th obstacle nail 4o, 4o is provided in the vicinity of the third ordinary winning opening 23, and another obstacle nail 4 is arranged between the 12th obstacle nail 4o, 4o and the third ordinary winning opening 23. Therefore, the game ball that has passed between the pair of twelfth obstacle nails 4o, 4o is guided to the third normal winning opening 23. Since the game balls that have flowed into the third normal winning opening 23 are collected as described above, the gaming balls that have passed between the pair of twelfth twelfth obstacle nails 4o, 4o are guided to the second variable winning opening 12. Absent.

In other words, the pair of eighth obstacle nails 4j, the pair of ninth obstacle nails 4k, the pair of tenth obstacle nails 4m, the pair of eleventh obstacle nails 4n, and the pair of twelfth obstacle nails 4o, respectively, Is partitioned.
Further, the obstacle nails 4a, 4b, 4c, 4d, and 4e around the first variable prize opening 11 and the obstacle nails 4g, 4h, 4j, 4k, 4m, 4n, and 4o related to the second variable prize opening 12 are provided. When compared, it can be said as follows.

A pair of obstacles for guiding a game ball to the second variable winning opening 12 is a gradient with respect to a horizontal plane of a line connecting the pair of obstacle nails 4a, 4b, 4c for guiding the game ball to the first variable winning opening 11. It is smaller than the gradient with respect to the horizontal plane of the line segment connecting the nails 4g and 4h.
In addition, the number of the pair of obstacle nails 4j, 4k, 4m, 4n, 4o that do not guide the game ball to the second variable winning opening 12 is a pair of obstacle nails 4d, 4e that do not guide the game ball to the first variable winning opening 11. More than the number of.

As a result, the ratio of the game balls led to the obstacle nails 4g, 4h, 4j, 4k, 4m, 4n, and 4o related to the second variable winning opening 12 to the second variable winning opening 12 is the first variable winning opening. 11 can be said to be lower than the rate at which the game balls led to the obstacle nails 4a, 4b, 4c, 4d, 4e around 11 reach the first variable winning opening 11.
Therefore, when the first and second variable winning holes 11 and 12 are compared, the game ball flowing down the board surface of the game board 2 is more easily guided to the first variable winning hole 11 than the second variable winning hole 12. In other words, it is difficult to enter the game ball into the second variable winning opening 12 that is opened only when the degree of profit given to the player is relatively low (second special profit state and small hit state). . As a result, the player cannot easily win even if the second variable winning opening 12 is open, and the fluctuation in the winning rate does not increase, so that the gaming machine performance as intended can be realized. In addition, the first variable winning slot 11 can be easily won, and the winning at the first variable winning slot 11 is only a hit with a relatively high profit degree or a hit with a high selection rate per hit. As a result, the game is sharpened, and the expectation of winning with the opening of the first variable winning opening 11 can be increased, thereby preventing a decrease in the interest of the game.

FIG. 9 is a block diagram showing an electrical configuration of the ball game machine 1.
The ball game machine 1 includes a main control board 100 that controls game operation control, an effect control board 101 that controls effect control, and a payout control board 102 for paying out game balls from the ball game machine 1. Yes.
The payout control board 102 includes a microcomputer including a CPU 102A, a RAM 102B, a ROM 102C, and the like, and is directly connected to the main control board 100. The payout control board 102 is connected with a prize ball payout device 50 as a control target.

  The effect control board 101 is connected to the main control board 100 via the effect interface board 103. The liquid crystal display control board 101 includes a microcomputer including a CPU 101A, a RAM 101B, and a ROM 101C. A liquid crystal display control board 104 is connected to the effect control board 101 via an effect interface board 103. The liquid crystal display control board 104 includes a microcomputer including a CPU 104A, a RAM 104B, and a ROM 104C. A liquid crystal display unit 16 is connected to the liquid crystal display control board 104 as a control target.

  The main control board 100 includes a microcomputer including a CPU 100A, a RAM 100B, and a ROM 100C. The main control board 100 is connected to the first and second special symbol display means 25 and 26 and the normal symbol display means 28 as control targets. Further, the main control board 100 has first and second special symbol start port entrance sensors for detecting entrance to the first and second special symbol start ports 6 and 7 (refer to FIG. 1 together). Detection outputs from 106 and 107 are directly inputted.

  Further, the main control board 100 detects from the normal gate passage sensor 108 for detecting that the game ball has passed through the normal symbol gate 15 (see FIGS. 1 and 7) via the game board relay board 105. Output, detection output from the first variable winning opening entrance ball sensor 109 for detecting that a game ball has entered the first variable winning opening 11 (see also FIG. 1 and FIG. 7), second variable winning opening The detection output from the prize winning detection switch 60 and the detection outputs from the first and second winning detection switches 71 and 73 are input.

  The main control board 100 includes an electric tulip driving mechanism (including solenoids, for example) 111 for driving the electric tulip accessory 8 (see FIG. 1) via the game board relay board 105, and the first. A first variable prize opening opening / closing mechanism (including solenoids, for example) 112, a solenoid 54 and the like for opening and closing the variable winning combination 13 (see FIG. 1) are connected as control targets.

A speaker 114 and a game lamp 115 disposed on the front surface of the main body (front door, etc.) of the ball and ball game machine 1 are connected to the effect interface board 103 as control targets via a frame relay board 113. .
The production control board 101 determines the specific production contents of the liquid crystal display unit 16 based on the control command signal from the main control board 100, and outputs a control command signal describing the production contents to the controlled object. . Specifically, the control command signal output from the effect control board 101 is given to the liquid crystal display control board 104 via the effect interface board 103. The liquid crystal display control board 104 controls the display of the liquid crystal display unit 16 based on the content of a control command signal (in this case, a control command signal for liquid crystal control) sent from the effect control board 101.

The control program of the main control board 100 includes a system reset process that is a main process that is started based on the restoration or input of the power supply voltage.
Execution of the system reset process is started when power is turned on and a system reset signal from a power supply board (not shown) is input to the main control board 100. When system reset processing is executed, the power is turned on without clearing the RAM, such as when recovering from a power failure, or the power is turned on while the RAM is being cleared, such as when the amusement store is opened. The case where it will be in a state can be mentioned.

In these cases, the CPU 100A first sets itself to an interrupt disabled state and initializes the values of the respective registers built in the CPU 100A. Next, the CPU 100A waits until the initial setting of peripheral substrates (for example, substrates such as the payout control substrate 102 and the effect control substrate 101) is completed.
In addition, a voltage drop signal having a voltage level (for example, an ON state) indicating a power-on state is input to the main control board 100 as the power is turned on. When the voltage drop signal is at a voltage level indicating a power-on state, the CPU 100A thereafter monitors whether or not a power-on command signal indicating that the payout control board 102 has started up normally is input from the payout control board 102. To do.

  Next, the CPU 100A to which the power-on command signal is input determines whether the RAM clear signal received from the power supply board (not shown) is at the L level (the level when the power is turned on while performing the RAM clear operation). If the RAM clear signal is at the L level, the entire area of the RAM 100B is cleared to zero, and a RAM clear command signal for notifying the RAM clear is output to the peripheral substrates. On the other hand, when the RAM clear signal received by the main control board 100 is at the H level, it is determined whether or not the data (backup data) stored in the RAM 100B is valid. Specifically, the checksum (data error detection code) calculated by the CPU 100A based on the backup data stored in the RAM 100B at that time is used as the backup checksum stored in the SUM storage area of the RAM 100B. If they match, the backup data is valid if they match, and the backup data is invalid if they do not match.

When the execution of each of these processes is completed, the system reset process is terminated, and the main process (main loop process) enters an infinite loop. During the infinite loop of the main process, update processing is executed for various counters with the CPU 100A set to the interrupt disabled state, and after the execution ends, the CPU 100A is returned to the interrupt enabled state.
During an infinite loop of the main process, a maskable timer interrupt process is executed every 4 msec. More specifically, in the CPU 100A, on the condition that the CPU 100A is in the interrupt permitted state, the main process is interrupted every 4 msec, and the timer interrupt process is executed.

  FIG. 10 is a flowchart showing the flow of the timer interrupt process of the main control board 100. When the timer interrupt process is started, the power supply abnormality check process is promptly executed without saving the CPU 100A register (step S1). In this power supply abnormality check process, the level of a voltage drop signal supplied to the main control board 100 from a power supply board (not shown) connected to the main control board 100 is determined. When it is detected over one or a plurality of timer interruption processes that the level of the voltage drop signal indicates a level indicating power interruption, the process proceeds to the backup process.

  On the other hand, if it is determined that the voltage drop signal is at a level that does not indicate power-off, a timer subtraction process (timer management process) is performed for each timer that manages the game operation time (S2: timer). Management process). The timer to be subtracted here is mainly used for managing the opening time of the electric tulip accessory 8 (see FIG. 1) or the opening time of the first and second variable winning ports 11, 12 (see FIG. 1). Is to be done.

  Next, an input management process is executed (step S3). The input management process stores the contents of detection outputs of various sensors provided in the ball game machine 1 (for example, whether the various detection sensors output an on / off signal, whether they are on or off), This is a process of periodically updating data based on the. As various sensors, for example, the special symbol start entrance ball sensors 106 and 107 (see FIG. 9), the normal gate passage sensor 108 (see FIG. 9), the first variable winning entrance entrance ball sensor 109 (see FIG. 9), and the second variable. Examples include a winning opening winning detection switch 60 (see FIGS. 6A and 6B), first and second winning detection switches 71 and 73 (see FIG. 3), and the like.

Next, it is used for the value of the normal symbol determination random number counter (not shown) used in the normal symbol determination in the normal symbol management process (step S7) described later, and the jackpot determination in the special symbol management process (step S9) described later. The value of the jackpot determination random number counter (not shown) is updated (S4: timer interrupt random number management process).
Next, an error management process is performed to determine whether or not the supply of game balls to the ball supply mechanism (not shown) for supplying game balls to the prize ball payout device 50 is stopped or whether or not the game balls are clogged (step S5). . In this error management process, it is also determined whether or not an abnormality has occurred inside the ball game machine 1.

Next, in order to instruct the number of payouts to the winning ball payout device 50 corresponding to the number of payouts of game balls that have entered (winning) the winning balls 6, 7, 11, 12, 21, 22, and 23, A prize ball management process for confirming and creating command signal data is performed (step S6).
Next, normal symbol management processing is performed (step S7). In this normal symbol management process, a normal symbol determination process (equivalent to the above-described normal symbol lottery) for determining whether or not to expand the electric tulip accessory 8 is executed. More specifically, the value of the normal symbol determining random number obtained from the normal symbol determining random number counter (not shown) updated by the timer interrupt random number management process in step S4 is compared with the numerical value per normal symbol.

When the normal symbol determination random number matches the numerical value per normal symbol in the normal symbol determination process, a process for expanding the electric tulip accessory 8 is executed, and then the electric tulip accessory 8 The process which implement | achieves this expansion operation is performed (S8: normal electric-powered article management process).
Next, a special symbol management process is performed (step S9). In this special symbol management process, a jackpot determination process for determining whether or not to execute the special profit state is executed. More specifically, the value of the big hit determination random number obtained from the big hit determination random number counter (not shown) updated by the random number management process in timer interruption in step S4 is compared with the big hit value.

  When the value of the jackpot determination random number matches the jackpot value in the jackpot determination process, the opening operation of the first variable winning port 11 (opening / closing operation of the first variable winning combination 13) or the second variable winning port 12 A process for the opening operation (opening / closing operation of the second variable winning combination 14) is performed, and thereafter, a process for realizing the opening operation of the variable winning opening 11, 12 is executed (S10: Special electric component management) processing).

Next, a lamp management process for turning on and off a predetermined lamp managed by the main control board 100 is executed (step S11).
Next, after returning the CPU 100A to the interrupt permission state (step S12), the timer interrupt process is ended. As a result, the routine of the timer interrupt process is exited, and an infinite loop main process (system reset process) is executed. In this main processing, monitoring of voltage abnormality and confirmation of presence / absence of timer interrupt processing are performed.

FIG. 11 is a flowchart showing the flow of the normal symbol management process in step S7 shown in FIG.
The RAM 100B is provided with a normal symbol storage area (not shown). The normal symbol holding storage area can store, for example, up to five normal symbol random numbers for normal symbol determination, one of which is for executing symbol variation of the normal symbol display means 28, and the remaining four are normal symbol display. The information is stored for holding the symbol changing operation of the means 28.

During the game by the ball game machine 1, the CPU 100A monitors the passing of the game ball in the normal symbol gate 15. That is, when a game ball passes through the normal symbol gate 15, the detection output (for example, on / off state) of the normal gate passage sensor 108 changes. Thereby, the passage of the game ball with respect to the normal symbol gate 15 is detected.
When a game ball for the normal symbol gate 15 passes in a state where the number of start memories stored for holding in the normal symbol holding storage area is less than the upper limit of the number of held balls (the number of held balls MAX, for example, four). YES in step S21 and NO in step S22), the value of the normal symbol reserved ball number counter (value of the normal symbol reserved ball number) is incremented (+1) (step S23), and is acquired according to the entered ball The starting memory is stored in the normal symbol storage area (step S24).

Specifically, in step S24, CPU 100A obtains a normal symbol determination random number from a normal symbol determination random number counter (not shown), and stores the normal symbol determination random number in the normal symbol hold storage area.
Then, only when the electric tulip accessory 8 is not being expanded (NO in step S25, when the normal symbol is not hit (when the normal hit flag = “5A [H]”)), the determination process described below is performed. Executed.

  In this case, processing is performed according to the fluctuation display status by the normal symbol display means 28, that is, the content of the normal symbol operation status. When the normal symbol motion status is “00 [H]”, the value of the normal symbol motion suspension count is decremented by “−1” on condition that the normal symbol motion suspension count is not zero (step S29). It is determined whether or not the hit determination random number is a win (step S30).

  That is, the game ball in a state where the symbol changing operation of the normal symbol display means 28 is not performed, the electric tulip accessory 8 is not being expanded, and the symbol changing operation of the normal symbol display means 28 is not suspended. Is passed through the normal symbol gate 15, the random value for determining the normal symbol obtained in response to the passage is stored in the normal symbol holding storage area for execution, and then the normal symbol determining random number is immediately stored. The numerical value and the numerical value per ordinary symbol are compared. On the other hand, when a game ball passes through the normal symbol gate 15 while the normal symbol determination random number for execution is already stored in the normal symbol holding storage area or during the expansion operation of the electric tulip accessory 8 The random symbol value for determining the normal symbol acquired in response to the passage is stored in the normal symbol holding storage area for holding. The normal symbol determination random number stored in the normal symbol hold storage area is stored in the normal symbol hold storage area. When the execution of the symbol variation operation of the normal symbol display means 28 corresponding to the normal symbol determination random number for execution ends, the electric tulip On the condition that the combination object 8 is not being expanded, it is sequentially carried up for execution, and the normal symbol determination random number value is compared with the numerical value per normal symbol. Then, when the normal symbol determination random number value and the numerical value per normal symbol coincide with each other, a win is made. If the random number for normal symbol determination and the numerical value per normal symbol match, the normal hit flag (“5A [H]”) is stored in the RAM 100B.

  Thereafter, a stop symbol of a normal symbol corresponding to whether or not it is a win is created (stop symbol creation process) (step S31), and a variation time of the normal symbol is set (step S32). In this case, when the internal state of the ball game machine 1 is when the support game is not executed, the symbol change time of the normal symbol display means 28 is set to 30 seconds, for example, and the internal state of the ball game machine 1 is When the support game is in progress, the symbol change time of the normal symbol display means 28 is set to 3.0 seconds, for example.

  On the other hand, when the content of the normal symbol operation status is “01 [H]”, the CPU 100A executes the normal symbol changing process (step S33). On the other hand, when the content of the normal symbol operation status is “02 [H]”, for example, the CPU 100A executes processing during the normal symbol confirmation time (step S34). Next, the normal symbol display data used for the display of the normal symbol display means 28 is updated (step S35), and then this normal symbol management process is returned.

Instead of storing the normal symbol determination random number value in the normal symbol holding storage area of the RAM 100B, the result of winning by comparing the acquired normal symbol determination random number value with a predetermined numerical value per normal symbol is stored. It goes without saying that it may be possible to do so.
FIG. 12 is a flowchart showing the flow of the ordinary electric accessory management process in step S8 shown in FIG.

  When the result of the normal symbol lottery is a win, that is, when the normal hit flag stored in the RAM 100B is “5A [H]” (YES in step S41), the expansion operation of the electric tulip accessory 8 is then performed. It is executed (steps S42 to S49). The execution time of the expansion operation of the electric tulip accessory 8 is timed by a normal electric accessory timer (not shown) composed of a subtraction timer, and the value of the normal electric accessory timer becomes “0” (step) Execution of this expansion operation is continued, YES in S46.

  Specifically, during the execution (in operation) of the expansion operation of the electric tulip accessory 8 (YES in step S42), the number of game balls that have entered the second special symbol start port 7 (second start port) Are counted. The number of game balls that enter the second special symbol start port 7 is always checked (monitored) (step S43), and when this number reaches the predetermined maximum number (upper limit) (YES in step S44). ) The value of the ordinary electric accessory timer is immediately set to “0” (step S45).

  If the value of the ordinary electric accessory timer is “0” (YES in step S46), the process proceeds to the end process of the expanding operation. Specifically, various set values are set according to the normal electric accessory operating status. For example, if the content of the normal electric accessory operation status is “02 [H]” (YES in step S48), the opening / closing operation setting of the electric tulip accessory 8 for the next operation is set (step S49). .

FIG. 13 is a flowchart showing the flow of the special symbol management process in step S9 of FIG.
During a game with the ball game machine 1, the CPU 100 </ b> A monitors the entrance of the game ball into the first special symbol start port 6 (see FIG. 1), and the game ball enters the first special symbol start port 6. When the golf ball has been hit, a predetermined ball entry process is performed (step S51: these are collectively referred to as “first start port check process”). Further, the CPU 100A monitors the entrance of the game ball into the second special symbol start port 7 (see FIG. 2), and when the game ball enters the second special symbol start port 7, the CPU 100A is predetermined. (Step S52: these are collectively referred to as “second starter check process”).

  FIG. 14 is a flowchart showing the flow of the first start port check process in step S51. The RAM 100B is provided with a first special symbol reservation storage area (not shown). In the first special symbol holding storage area, for example, a maximum of five random numbers for jackpot determination, random numbers for special symbols, random numbers for fluctuation patterns (the above random numbers are collectively referred to as “start-up memory”, the same shall apply hereinafter). Can be stored. One of the start memories is stored in the first special symbol holding storage area for execution of symbol variation of the first special symbol display means 25 (see FIG. 1), and the remaining four are stored in the first special symbol display means 25. It is stored in the first special symbol holding storage area for use in holding the variable operation. The number of starting memories stored for holding in the first special symbol holding storage area is stored in a first special symbol holding ball counter (not shown) provided in the RAM 100B.

During the game by the ball game machine 1, the CPU 100A monitors the entry of the game ball into the first special symbol starting port 6. That is, when a game ball enters the first special symbol start opening 6, the detection output (for example, on / off state) of the first special symbol start opening entrance sensor 106 (see FIG. 9) changes. Thereby, the entrance of the game ball to the first special symbol starting port 6 is detected.
In the state where the number of starting memories stored for holding in the first special symbol holding storage area is less than the upper limit of the number of held balls (the number of held balls MAX, for example, four), a game is played in the first special symbol starting port 6 When a ball enters (wins at the first start opening) (YES in step S71 and NO in step S72), the value of the first special symbol reserved ball number counter (the value of the special figure 1 reserved ball number) is incremented. At the same time (+1) (step S73), the start memory obtained in response to the entry is stored in the first special symbol storage area (step S74).

  Specifically, in step S74, the CPU 100A acquires a big hit determination random number from a big hit determination random number counter (not shown) and also acquires a special symbol random number from the special symbol random counter (not shown). The random number for determination and the random number for special symbol are stored in the first special symbol holding storage area. Further, the CPU 100A obtains a variation pattern random number from a variation pattern random number counter (not shown), and stores the variation pattern random number in a first special symbol holding storage area provided in the RAM 100B. Thereafter, the first start opening check process is returned.

  The first and second special symbol display means 25, 26 are not in a symbol changing operation, are not in a special profit state, and the first and second special symbol display means 25, 26 are not suspended in the symbol changing operation. When a game ball enters the first special symbol start port 6, the start memory acquired in response to the ball is stored in the first special symbol hold storage area for execution. On the other hand, in the state where the start memory is already stored for execution in the first or second special symbol storage area, during the symbol changing operation of the first or second special symbol display means 25, 26, or in the special profit state When a game ball enters the first special symbol start opening 6, the start memory acquired in response to the incoming ball is stored in the first special symbol storage area for holding. The start memory stored for holding in the first special symbol storage area will be described later when the execution of the symbol changing operation of the first special symbol display means 25 corresponding to the start memory stored for execution is completed. For execution, on condition that the start memory is not already stored for execution in the second special symbol storage area, the symbol changing operation of the second special symbol display means 26 is not in progress, and the special profit state is not in effect. It is moved up sequentially. As a result, the symbol changing operation of the first special symbol display means 25 corresponding to the start-up memory that has been put on hold is sequentially executed.

Instead of storing the jackpot determination random number in the first special symbol reserved storage area of the RAM 100B, the winning result itself by comparing the determined jackpot determination random number with a predetermined jackpot value may be stored. Needless to say, it is good.
FIG. 15 is a flowchart showing the flow of the second start port check process in step S52. The RAM 100B is provided with a second special symbol reservation storage area (not shown). In the second special symbol storage area, for example, a maximum of five starting memories can be stored, one of which is used for the execution of symbol variation of the second special symbol display means 26 (see FIG. 1). The four are stored for holding the symbol variation operation of the second special symbol display means 26. The number of starting memories stored for holding in the second special symbol holding storage area is stored in a second special symbol holding ball number counter (not shown) provided in the RAM 100B.

During a game by the bullet ball gaming machine 1, the CPU 100 </ b> A monitors the entry of the game ball into the second special symbol starting port 7. That is, when a game ball enters the second special symbol start opening 7, the detection output (for example, on / off state) of the second special symbol start opening ball sensor 107 (see FIG. 9) changes. Thereby, the entrance of the game ball to the second special symbol start port 7 is detected.
In the state where the number of starting memories stored for holding in the second special symbol holding storage area is less than the upper limit of the number of held balls (the number of held balls MAX, for example, four), a game is played in the second special symbol start port 7 When a ball enters (wins at the second starting port) (YES in step S81 and NO in step S82), the value of the second special symbol reserved ball number counter (the value of the special figure 2 reserved ball number) is incremented. At the same time (+1) (step S83), the start memory acquired in response to the entered ball is stored in the second special symbol storage area (step S84).

  In step S84, specifically, the CPU 100A obtains the big hit determination random number from the big hit determination random number counter (not shown) and also acquires the special symbol random number from the special symbol random counter (not shown). The random number for determination and the random number for special symbol are stored in the second special symbol holding storage area. Further, the CPU 100A obtains a variation pattern random number from a variation pattern random number counter (not shown), and stores the variation pattern random number in a second special symbol holding storage area provided in the RAM 100B. Thereafter, the second start port check process is returned.

  The second special symbol is not in the state of the symbol change operation of the first and second special symbol display means 25, 26, in the special profit state, and in the state where the symbol change operation of the second special symbol display means 26 is not suspended. When a game ball enters the start port 7, the start memory acquired in accordance with the ball is stored in the second special symbol storage area for execution. On the other hand, in the state where the start memory is already stored for execution in the second special symbol holding storage area, during the symbol changing operation of the first or second special symbol display means 25, 26, or in the special profit state, the second When a game ball enters the special symbol start port 7, the start memory acquired for the ball is stored in the second special symbol storage area for holding. The start memory stored for holding in the second special symbol storage area is the first memory when the execution of the symbol changing operation of the second special symbol display means 26 corresponding to the start memory stored for execution ends. The special symbol display means 25 is sequentially moved up for execution on the condition that the symbol changing operation is not being performed and the special profit state is not in effect. As a result, the symbol changing operation of the second special symbol display means 26 corresponding to the start-up memory that has been put on hold is sequentially executed.

Instead of storing the jackpot determination random number in the second special symbol holding storage area of the RAM 100B, the result of winning by comparing the acquired jackpot determination random number with a predetermined jackpot value may be stored. Needless to say, it is good.
With reference to FIG. 13 again, the flow of the special symbol management process will be continuously described.
After executing the first start-up port check process in step S51 and the second start-up port check process in step S52, the CPU 100A refers to the value of the small hitting flag (not shown) provided in the RAM 100B. It is checked whether or not the machine 1 is executing a small hit game (step S53). When the small hit game is not executed (NO in step S53), the CPU 100A then refers to the value of the condition device operation flag (not shown) provided in the RAM 100B, and the ball game machine 1 is special. It is checked whether the profit state is being executed (step S54).

  When the value of the small hit / medium flag (for example, 2-byte configuration) provided in the RAM 100B is “5A [H]”, for example, the small hit game is being executed. In the case of [H], it is assumed that the small hit game is not executed. Further, when the value of the condition device operation flag (2-byte configuration) provided in the RAM 100B is, for example, “5A [H]”, it is determined that the special profit state is in effect, and the value of the condition device operation flag is, for example, “00 [ H] ”, it is assumed that the special profit state is not executed.

  If the ball game machine 1 is in a small hit game (and is not executed in the special profit state) (YES in step S53), or if the ball game machine 1 is not executed in the small hit game and special If the profit state is not executed (YES in step S54), then the special symbol display data used for display of the special symbol display means 25 and 26 is updated, and then the special symbol management process returns. Is done.

  On the other hand, if the ball game machine 1 is in the special profit state (YES in step S54), then the special symbol operation status is checked. When the content of the special symbol operation status is, for example, “00 [H]” or “01 [H]”, the CPU 100A executes a special symbol variation start process (step S57), and the content of the special symbol operation status is, for example, If it is “02 [H]”, the CPU 100A executes the special symbol changing process (step S58). On the other hand, when the content of the special symbol operation status is “03 [H]”, for example, the CPU 100A executes a special symbol confirmation time process (step S59). Next, the special symbol display data used for the display of the special symbol display means 25 and 26 is updated (step S60), and then the special symbol management process is returned.

FIG. 16 is a flowchart showing the flow of the special symbol variation start process shown in step S57 of FIG.
In the special symbol variation start process in step S57, first, it is checked whether or not there is a start memory suspension based on the ball entering the second special symbol start port 7 (special figure 2 number of retained balls = 0?). ). If there is no hold of the start memory, it is checked whether or not there is a hold of start memory based on the entrance of the first special symbol start port 6 (step S92). . When both the value of the first special symbol reserved ball number counter (not shown) and the value of the second special symbol reserved ball number counter (not shown) are “0”, the special symbol operation status (special symbol operation) at that time On condition that the (status) is not “00 [H]” (YES in step S93), the CPU 100A of the main control board 100 transmits a customer waiting demo command to the effect control board 101 (step S94). After transmitting the customer waiting demo command, the special symbol operation status (special symbol operation status) is set to “00 [H]” (step S95).

  On the other hand, in the process of step S91, when the value of the second special symbol reserved ball number counter (not shown) is “1” or more (NO in step S91), the number of reserved balls of the first special symbol (special symbol 1). Is decremented (−1) (step S96), and the CPU 100A of the main control board 100 transmits a hold subtraction command to the effect control board 101 (step S97).

  When the value of the second special symbol reserved ball number counter is “0” and the value of the first special symbol reserved ball number counter (not shown) is “1” or more (YES in step S91 and NO in step S92). ), The number of reserved balls of the second special symbol (special figure 2) is decremented (−1) (step S96), and the CPU 100A of the main control board 100 transmits a hold subtraction command to the effect control board 101 ( Step S97).

  That is, in the process of step S96, the value of the first or second special symbol reserved ball number counter (not shown) corresponding to the special symbol subject to the special symbol variation is decremented (−1) and the special symbol is decremented (−1). In the first or second special symbol hold storage area corresponding to, the start-up memory previously stored for hold or the newly-stored start-up memory is stored for hold.

After step S97, special symbol operation confirmation data is set (step S98), and then random number determination processing (step S99), special symbol creation processing (step S100), gaming state transition preparation processing (step S101), and special symbol ( Special figure) Fluctuation pattern creation processing (step S102) is executed in this order.
In the random number determination process in step S99, the value of the big hit determination random number included in the execution start memory is compared with the big hit value to determine whether the special profit state is executed or not (a big hit). Judgment). If it is determined that the game is a big hit, the condition actuator flag is set to “5A [H]”. Further, in the random number determination process in step S99, it is determined whether or not the small hit game is executed by comparing the big hit determination random number value included in the start memory for execution with the small hit value. (Small hit judgment). When it is determined that a small hit is made, the small hitting medium flag is set to “5A [H]”.

Further, in the special symbol creation process in step S100, the special symbol to be displayed on the special symbol display means 25, 26 after the symbol variation operation is determined based on the result of the big hit determination and the value of the special symbol random number included in the start memory. It is determined.
Also, in the special symbol variation pattern creating process in step S102, the special symbol variation operation in the special symbol display means 25, 26 is based on the result of the big hit determination and the random pattern random symbol value included in the startup memory. Determine the pattern.

After completion of the special symbol variation pattern creation process in step S102, the special symbol variation flag (special symbol 1 or 2 variation flag) of the special symbol which is the subject of variation, out of the first special symbol variation flag or the second special symbol variation flag. ) Is set to “5A [H]” (step S103).
Thereafter, based on the result of the jackpot determination and the value of the random number for the special symbol included in the start memory, a command (effect designating command) of the changing design pattern of the effect design in the liquid crystal display unit 16 is created, and the effect control is performed on the command. It transmits toward the board | substrate 101 (step S104, S105). Thereafter, various settings for starting the change are made (step S106), and then the special symbol change start process shown in step S57 of FIG. 13 is ended.

FIG. 17 is a flowchart showing the flow of the special electric accessory management process shown in step S10 of FIG.
In the special electric bonus management process, it is checked whether the operation of the variable winning prize this time corresponds to the special profit state (the first profit state or the second profit state) or the small hit game. Specifically, the CPU 100A refers to the value of the small hitting medium flag (not shown) and the condition device operation flag (not shown) provided in the RAM 100B.

When the value of the small hitting flag provided in the RAM 100B is “5A [H]” (YES in step S121), the small hit game is executed (step S134), and then the special electric accessory management process returns. Is done.
Further, when the value of the small hitting / measuring flag provided in the RAM 100B is, for example, “00 [H]”, and the value of the condition device operation flag provided in the RAM 100B is, for example, “5A [H]”. In the case of (NO in step S121 and YES in step S122), the execution of the special profit state is performed, and then the special electric accessory operation status is checked. The operation status of the special electric accessory is, for example, a value of 00 [H], 01 [H], 02 [H], 03 [H], 04 [H], and 05 [H] depending on the progress degree of the special profit state. (The value increases as the degree of progress increases).

  When the content of the operation status of the special electric accessory is, for example, “00 [H]” (YES in step S123), processing for starting a special profit state such as execution of a fanfare or the like (big hit start processing) is executed. (Step S128). If the content of the special electric accessory operation status is “01 [H]” (NO in step S123 and YES in step S124), the first variable winning combination 13 (see FIG. 1) or the second variable winning combination is displayed. Processing for starting the opening / closing operation of the accessory 14 (see FIGS. 5, 6A and 6B) (special electric accessory operation starting processing) is executed (step S129). Further, if the content of the special electric accessory operation status is “02 [H]” or “03 [H]” (NO in steps S123 and S124, YES in step S125, NO in step S125, and YES in step S126) ), A process for opening / closing the first variable winning combination 13 (see FIG. 1) or the second variable winning combination 14 (see FIG. 5 and FIG. 6) is performed (a process during the operation of the special electric combination) (step). S130, S131). Further, when the content of the special electric accessory operation status is, for example, “04 [H]” (NO in steps S123, S124, S125, and S126 and YES in step S127), the first variable winning combination 13 or the second A determination process for determining whether or not to continue the opening / closing operation of the variable winning combination 14 (special electric accessory operation continuation determination process) is executed (step S132). Further, when the content of the special electric accessory operation status is, for example, “05 [H]” (NO in steps S123, S124, S125, S126, and S127), a process for ending the special profit state (end of jackpot) Process) is executed (step S133). After each process of steps S128 to S133, the special electric accessory management process is returned.

  FIG. 18 is a diagram showing an example of the special symbol-hit type table for the first special symbol stored in the ROM 100C. In the special symbol-hit type table for the first special symbol, the type of the first special symbol displayed on the first special symbol display means 25 at the time of big hit, small hit and loss, and the type of the big hit, small hit and loss Are stored in association with each other. The special symbol-hit type table for the first special symbol is a special symbol-hit type table 121A for jackpot shown in FIG. 18 (a), and a special symbol-hit type for small jacks shown in FIG. 18 (b). A table 121B and a special symbol-hit type table 121C for loss shown in FIG. 18C are provided. The “symbol number” shown in FIG. 18 is a symbol number corresponding one-to-one with the first special symbol.

In the ball game machine 1, the first to fourth jackpot games as described above are prepared as jackpot hit types, and as shown in FIG. 18, there are 23 types of first jackpots as the first special symbol for jackpot. Special designs are available. FIG. 18 also shows the selection ratio of each first special symbol in the special symbol lottery.
01 [H] and 02 [H] are symbol numbers corresponding to the first big hit. The first jackpot is a jackpot (15R probability change) in which the first special profit state described below is executed after the jackpot symbol is displayed, and after the special profit state is executed, a probability variation game with a support game is started. . In the first special profit state, the first variable winning is performed until a predetermined time (for example, 30 seconds) elapses or until a predetermined maximum number of winning balls (for example, 10 balls) enter the first variable winning opening 11. With the opening operation of opening the mouth 11 as one round game, such an opening operation is performed for many round games (for example, 15 rounds) with an interval between round games (for example, 1.0 seconds) interposed therebetween. The number of prize balls that can be obtained by the player in the series of first special profit states is, for example, about 1500 (10 (balls / ball) × 10 (ball / round game) × 15 (round)). The selection ratio per first big hit is, for example, 50%.

  03 [H] is a symbol number corresponding to the second big hit. The second jackpot is a jackpot (2R probability change 1) in which the second special profit state described below is executed after the jackpot symbol is displayed, and the probability variable game with a support game is started after the special profit state is executed. . In the second special profit state, the second time until a predetermined time (for example, 0.2 seconds) elapses or until a predetermined maximum number of winning balls (for example, 10 balls) enter the second variable winning opening 12. An opening operation such as opening the variable winning opening 12 is regarded as one round game, and such an opening operation is performed in a predetermined small number of round games (for example, 2 rounds) with an interval between round games (for example, 1.0 second) interposed therebetween. Done. As described above, the second variable winning opening 12 is arranged at a position where the game ball in the gaming area S is difficult to be guided, and the opening time of the second variable winning opening 12 is only 0.2 seconds. Hardly receives game balls. In other words, the second variable prize opening 12 is configured so that the opening time and the number of opening operations are smaller than those of the first variable prize opening 11.

Therefore, during the opening operation of the second special profit state, the player can obtain almost 0 prize balls. The selection ratio per second jackpot is, for example, 3.0%.
04 [H], 05 [H], 06 [H], 07 [H], 08 [H], 09 [H], 0A [H], 0B [H], 0C [H], 0D [H], 0E [H] and 0F [H] are symbol numbers corresponding to the third big hit. The third jackpot is a jackpot (2R probability variation 2) in which the above-described second special profit state is executed after the jackpot symbol is displayed and the probability variation game is continuously started after the special profit state is executed. In the third big hit, if the state immediately before the big hit is in a support game, the support game is executed even after the big hit, and if the state immediately before the big hit is a non-support game, the support game is also executed after the big hit. Is not to be executed. The selection ratio per third big hit is, for example, 27.0%.

  10 [H], 11 [H], 12 [H], 13 [H], 14 [H], 15 [H], 16 [H] and 17 [H] are symbol numbers corresponding to the fourth big hit. is there. The fourth jackpot is a jackpot (2R non-probable change) in which the above-described second special profit state is executed after the jackpot symbol is displayed and the probability variation game is not executed after the special profit state is executed. For the fourth big hit, if the state immediately before the big hit is a support game, the support game is executed even after the big hit, and if the state immediately before the big hit is a non-support game, the support game is also executed after the big hit. Is not to be executed. The selection ratio per fourth jackpot is, for example, 20.0%.

Also, 00 [H] is a symbol number corresponding to a loss (a state that is neither a small hit game nor a big hit).
FIG. 19 is a diagram showing an example of the special symbol-hit type table for the second special symbol stored in the ROM 100C. In the special symbol-hit type table for the second special symbol, the type of the first special symbol displayed on the second special symbol display means 26 at the time of big hit, small hit and loss, and the type of the big hit, small hit and loss Are stored in association with each other. The special symbol-hit type table for the second special symbol includes a special symbol-hit type table 122A for big hits shown in FIG. 19 (a), and a special symbol-hit type for small hits shown in FIG. 19 (b). A table 122B and a special symbol-hit type table 122C for loss shown in FIG. 19C are provided. The “symbol number” shown in FIG. 19 is a symbol number corresponding to the second special symbol on a one-to-one basis.

As shown in FIG. 19, five types of second special symbols are prepared as the second special symbol for jackpot. FIG. 19 also shows the selection ratio of each second special symbol in the special symbol lottery.
01 [H], 02 [H] and 03 [H] are symbol numbers corresponding to the first big hit. The selection ratio per first big hit is 70%, for example. 04 [H] is a symbol number corresponding to the third big hit (2R probability variation, equivalent to “2R probability variation 2” shown in FIG. 18). The selection ratio per third jackpot is, for example, 10.0%. 05 [H] is a symbol number corresponding to the fourth big hit. The selection ratio per fourth jackpot is, for example, 20.0%.

06 [H] is a symbol number corresponding to the small hit game. Also, 00 [H] is a symbol number corresponding to a loss (a state that is neither a small hit game nor a big hit).
As described above, in the first special profit state (special profit state in which the first variable winning slot 11 is opened), for example, there are about 1500 prize balls that can be obtained by the player, while in the second special profit state ( In the special profit state in which the second variable winning opening 12 is opened), for example, about 0 prize balls can be obtained by the player. Further, as shown in FIGS. 18 and 19, the selection ratio of the first special profit state in the big hit with the first special symbol is 50%, whereas the second special profit in the big special hit with the second special symbol is 50%. The state selection ratio is 70%. When the support game is not executed, the electric tulip accessory 8 rarely expands, and as a result, it is difficult to enter the second special symbol starting port 7, so that A player who wants to play a game is likely to be in a state in which a support game is frequently executed, that is, a probability variation game. In other words, since a large amount of game balls can be obtained for the player during the probability variation game, the player's interest is greatly improved.

FIG. 20 is a diagram illustrating the transition of the effect mode.
In this bullet ball game machine 1, a plurality of effect modes (for example, four types of effect modes) are provided, and a screen with a different display screen or background screen of the liquid crystal display unit 16 is set for each effect mode. Specifically, the A mode (mode A shown in FIG. 21 which is the normal mode), the B mode (mode B shown in FIG. 21), the C mode (mode C shown in FIG. 21), and the probability variation confirmation mode (probability variation confirmation mode). 4 types of modes are prepared. The probability variation confirmation mode is an effect mode that clearly indicates that a probability variation game with a support game is being executed. The A mode is an effect mode that is a so-called normal mode, and is an effect mode in which the probability that a probability variation game is being executed is relatively low. The C mode is an effect mode that suggests that the probability during the probability variation game is high, and the probability that the probability variation game is being executed is relatively high. The B mode is an effect mode that suggests that the probability of the probability variation game is medium, and the probability that the probability variation game is executed is an intermediate probability between the A and C modes. In other words, among the three performance modes excluding the probability variation confirmation mode, the expected value of being in the probability variation game is the highest in the C mode and the lowest in the A mode.

In the A mode, the B mode, and the C mode, no support game is executed. Further, the A mode may be an effect mode in which the probability variation game is not executed.
FIG. 21 is a diagram showing the distribution tables 131 and 132 in the effect mode stored in the ROM 101C of the effect control board 101.
In the ball game machine 1, after the end of the special profit state associated with the jackpot at a predetermined timing (for example, at the start of fluctuation, when the jackpot occurs, after the jackpot ends, may be an appropriate timing determined in advance depending on the content of the effect to be determined) The internal state of the ball game machine 1, that is, whether or not the probability variation game is executed and the specific contents thereof are determined. In other words, after the special profit state ends, the internal state of the ball game machine 1 changes. A distribution table for determining the transition destination of the internal state is stored in the ROM 100C of the effect control board 101, and the CPU 100A of the effect control board 101 ends the special profit state in which the internal state changes in the ball game machine 1. At the same time, the effect mode is switched. The effect mode of the switching destination (transition mode destination) is determined based on the type of jackpot, that is, whether or not the probability variation game is executed.

As shown in FIGS. 21 (a) and 21 (b), after the end of the special profit state associated with the first jackpot, the probability variation confirmation mode (probability variation confirmation mode) is executed with a probability of 100%.
In addition, after the special profit state associated with the second jackpot ends, the probability variation confirmation mode (probability variation confirmation mode) is executed with a probability of 100%. The difference from the first big hit is only the number of game balls that can be acquired with the big hit, and a support game is generated after the big hit, as in the first big hit.

After the special profit state associated with the fourth big hit, the A mode is selected and executed with a probability of 40%, the B mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 30%. The After the end of the special profit state associated with the fourth jackpot, the probability variation confirmation mode is not selectively executed.
Further, the internal state after the end of the special profit state associated with the third jackpot differs depending on the internal state of the ball game machine 1 immediately before the big hit. That is, when the internal state of the ball game machine 1 immediately before the big hit is in the probability fluctuation game (when the support game is not executed and at the high probability), as shown in FIG. After completion of the special profit state, the A mode is selected and executed with a probability of 10%, the B mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 60%. On the other hand, when the internal state of the ball game machine 1 immediately before the big hit is when the probability variation game is not executed (when the support game is not executed and when the probability is low), it is shown in FIG. Thus, after the special profit state associated with the third big hit, the A mode is selected and executed with a probability of 60%, the B mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 10%. The

  Further, in the ball game machine 1, the effect mode is switched not only after the special profit state associated with the big hit but also after the small hit game ends when the small hit game occurs. The small hit game (small hit) is small hit A (for example, the small hit corresponding to the symbol numbers “18 [H]” and “19 [H]” shown in FIG. 18), and the symbol number “06 [ H] ”and a small hit B (for example, small hits corresponding to symbol numbers“ 1A [H] ”and“ 1B [H] ”shown in FIG. 18). The sorting table is different. Further, the internal state after the end of the small hit game differs depending on the internal state of the bullet ball game machine 1 immediately before the small hit game.

  When the internal state of the ball game machine 1 immediately before the small hit is in the non-execution of the probability variation game (at the low probability), the small hit corresponding to the small hit A is shown in FIG. After the game, the A mode is selected and executed with a probability of 40%, the mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 30%. Further, after the small hit game corresponding to the small hit B is completed, the A mode is selected and executed with a probability of 60%, the mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 10%. .

On the other hand, when the internal state of the ball game machine 1 immediately before the small hit is in the probability variation game (at high probability), the small hit corresponding to the small hit A is shown in FIG. After the game, the A mode is selected and executed with a probability of 10%, the mode is selected and executed with a probability of 30%, and the C mode is selected and executed with a probability of 60%.
That is, except when the probability variation fixed mode is selected, during the probability variation game, the C mode is generally preferentially selected as the effect mode (selection rate 60%), and when the probability variation game is not executed, the effect mode As a general rule, mode A is selected preferentially (selection ratio 60%). In addition, except for the case where the probability variation confirmation mode is selected, whether the mode B is in the probability variation game or the non-execution of the probability variation game, the mode B is a certain ratio (selection ratio 30%). ) Is selected.

  Referring to FIG. 20 again, the case where the mode is shifted to the B mode, the C mode, and the probability variation confirmation mode from the A mode is taken as an example, but the A mode, the C mode, and the The transition to each of the probability variation confirmation modes, the transition from the C mode to each of the A mode, the B mode, and the probability variation confirmation mode, and the A mode, the B mode, and the C mode from the probability variation confirmation mode. Needless to say, each can be migrated.

In addition, as a plurality of types of effect modes, the display images of the liquid crystal display unit 16 are not different from each other, but the background screen (color, design, etc. of the background screen) of the liquid crystal display unit 16 is different from each other. Also good.
In this embodiment, a probability variation latent state is suggested that suggests that the probability variation game is not being executed even when the probability variation game is being executed. And the opening mode of the 2nd special profit state in the 2nd variable prize opening 12 and the opening mode at the time of the small hit in the 2nd variable prize opening 12 are common.

  If the player is familiar with the specifications of the ball game machine or the player who has a lot of experience playing with the ball game machine, the mode of the opening / closing operation of the second variable winning combination 14 Depending on the combination with the performance or the like, there is a possibility that the opening operation is an opening operation in the second special profit state or an opening operation as a small hit game. That is, whether the internal state of the ball game machine 1 is a latent state of probability variation (during probability variation game (high probability)) or non-execution of probability variation game (low probability). May be relatively easy to spot.

  On the other hand, in this embodiment, the front of the second variable winning combination 14 is covered with the decorative plate 44, and the player cannot visually recognize the entire second variable winning combination 14, and the second variable winning combination 14 A part of the object 14 can only be viewed through the viewing window 95 (see FIG. 2). The visual recognition window 95 is configured by an arc-shaped small groove formed in the front portion of the second variable winning combination 14 in the decorative plate 44 as described above. Since the visual recognition window 95 is formed by the arc-shaped narrow groove, the posture of the blade member 59 (whether the posture is open or closed) can be grasped through the visual recognition window 95. The player cannot immediately recognize this posture. Therefore, the player cannot accurately grasp the opening / closing timing of the second variable winning combination 14. Accordingly, whether the internal state of the ball game machine 1 is a latent state of probability variation (during probability variation game (high probability)) or non-execution of probability variation game (low probability) Based on the opening / closing operation of the variable winning combination 14, the player cannot easily find out. Thereby, it is possible to eliminate the need to strictly adjust the specifications of each operation including the opening / closing operation of the second variable winning combination 14.

  In addition, the presentation performance is further improved by determining the production pattern and performing the production operation using the fact that the visibility of the opening operation is difficult. Specifically, for example, the pattern stops with a mere loss variation pattern, and the pattern shifts to the next variation, and the symbol stops with the same loss variation pattern as described above, and then the second special profit state is generated in a short time. In the second special profit state, a new production operation is not performed, so that the player can change the internal game state before recognizing the opening / closing operation. Can bring. According to the change in the internal state, the selection mode such as the production mode and the notice production is changed, and the production is decided to produce an unexpected performance for the player, or the internal frequency is estimated by the production. And can enhance the interest.

As mentioned above, although one Embodiment of this invention was described, this invention can be implemented also with another form.
For example, in the above-described embodiment, the viewing window 95 (see FIG. 2) is a groove for visually recognizing a part of the second variable winning combination 14, but as the shape of the viewing window 95, other shapes (for example, A straight groove, a small rectangular shape, a small circular / elliptical shape) or a hole can be employed.

  Further, the viewing window can be formed by a translucent or transparent resin member instead of a groove or a hole. In the case of forming with a translucent resin member, the viewing window can be provided in such a size that the whole of the second variable winning combination 14 can be seen without being part of it. This is because, if the viewing window is translucent, the player cannot accurately grasp the opening / closing timing of the second variable winning combination 14 even if the second variable winning combination 14 can be viewed.

Furthermore, you may make it the structure which cannot visually recognize the 2nd variable winning combination 14 from the front, without providing a visual recognition window.
Further, for example, as the opening / closing operation mode of the first variable winning combination 13, an operation mode in which the first variable winning combination 13 swings around the lower edge of the first variable winning slot 11 is adopted, and the second variable winning combination 13 is selected. As the opening / closing operation mode of the accessory 14, an operation mode of swinging around the swinging shaft (blade shaft 55) extending in the front-rear direction is adopted. However, as the opening / closing operation mode of the first variable winning combination 13, an operation mode of moving back and forth in the front-rear direction or an operation mode of swinging around the swinging shaft extending in the front-rear direction may be adopted. As the opening / closing operation mode of the variable winning combination 14, an operation mode that swings around the lower end edge of the second variable winning port that is rectangular in front view and an operation mode that moves back and forth in the front-rear direction can be adopted. You may make it employ | adopt the operation | movement aspect rock | fluctuated around a moving shaft.

  In the above-described embodiment, the configuration in which both the first and second variable prize winning openings 11 and 12 are disposed above the center of the board surface of the game board 2 in the vertical direction is given as an example. The first variable prize opening 11 may be arranged above the center of the board surface and the second variable prize opening 12 may be arranged below the center of the board surface of the game board 2. Furthermore, the first variable winning opening 11 may be disposed above the upper end of the liquid crystal display unit 16, and the second variable winning opening 12 may be disposed below the lower end of the liquid crystal display unit 16.

In this case, since many obstacle nails are planted on the surface of the game board 2, the second variable prize opening 12 is provided by arranging the second variable prize opening 12 in the lower part of the board surface of the game board 2. It can be difficult to guide the game ball aiming at. Thereby, it is possible to make it difficult for a game ball to enter the second variable winning opening 12.
In the above-described embodiment, the second special profit state in which the second variable prize opening 12 is opened and closed is more open than the first special profit state in which the first variable prize opening 11 is opened and closed. Although the number of movements is configured to be small, only one of the opening time and the number of opening movements of the variable prize opening is small, and the other is the same between the first special profit state and the second special profit state. You may comprise so that it may become.

Further, the symbol changing operation is executed in the order of entering the first special symbol starting port 6 or the second special symbol starting port 7 with respect to the changing order of the special symbols in the first special symbol displaying means 25 and the second special symbol displaying means 26. It may be a mode of changing the order of entering the balls, or a mode of simultaneous variation in which both perform the symbol variation operation independently.
Further, the CPU 100 does not determine whether or not it is a small hit based on the big hit determination random number, but provides a small hit random number generator, and sets the value of the small hit determination random number obtained from the small hit random number generator. Based on this, it may be determined whether or not it is a small hit.

In the above description, the first special symbol start port 6 and the second special symbol start port 7 have been described in the lower part of the game board 2. However, the first special symbol start port 6 and the second special symbol start port 6 have been described. You may employ | adopt the structure which arrange | positions the start port 7 in the left part and the right part of the game board 2. FIG.
In the above description, the first special symbol start port 6 and the second special symbol start port 7 and the second special symbol start port 7 are described as an example. The start ports 7 may be arranged at positions separated from each other on the game board 2. In this case, the game ball enters the second special symbol start port 7 in a state in which the pair of blades of the electric tulip accessory 8 is shown in a constricted state above the second special symbol start port 7 in the game board 2. It is desirable to provide a restricting member that prevents this.

In addition, although the gate (normal symbol gate 15) through which a game ball can pass is given as an example of the normal symbol starting means, a winning opening that allows a game ball to enter may be adopted as the normal symbol starting means.
Further, the number of first special symbol start ports 6 is not limited to one, and may be two or more. Further, the number of the second special symbol start ports 7 is not limited to one, and may be two or more.
In the above-described embodiment, the electric tulip accessory 8, the first variable winning combination 13 or the second variable winning combination 14 has been described as being controlled by the main control board 100. For example, when a control command from the main control board 100 is given to the accessory control unit, the control from the main control board 100 is connected to the main control board 100. Based on the command, the accessory control unit may control the electric tulip accessory 8, the first variable winning combination 13, or the second variable winning combination 14.

  In addition, various design changes can be made within the scope of matters described in the claims.
