Description

  The present invention relates to a winning device for gaming machines provided on a gaming board surface of a gaming machine such as a pachinko machine.

  Conventionally, in a pachinko machine that is a type of gaming machine, a symbol variation game that fluctuates a plurality of types of symbols has been performed in response to the winning of a game ball to a start winning device that is a type of a gaming machine winning device. . When the result of the symbol variation game is a big hit, a big hit game is awarded, and a plurality of rounds are continuously executed in one big hit game. In addition, the start winning device is integrally configured with an ordinary electric accessory consisting of a pair of blade members. Note that the pair of blade members are opposite to each other (clockwise, counterclockwise) due to the excitation action of the solenoid when the result of the normal symbol variation game that is triggered by the passing of the game ball to the gate is a hit. By turning in the direction), the game ball is switched from a closed state where the game ball cannot pass to an open state where the game ball can pass.

  However, when the pair of wing members are switched to the open state, if the game balls are guided along the upper surface of one of the wing members and flow into the start winning device vigorously, It may be guided along the upper surface of the blade member and jump out of the start winning device. In particular, when launching a game ball (so-called right-handed) aiming at the right area on the game board surface, the player launches the game ball at a high speed by turning the operation handle to the right. The speed is very fast. In this case, since the launched game ball is guided to the start winning device while maintaining a strong momentum, the game ball that has flowed in from one wing member (the right wing member) side becomes the other wing member ( The possibility of jumping out from the left blade member side is high. As a result, there is a problem that the expectation of the player who thinks that there is a possibility of being a big hit by starting the symbol variation game is betrayed.

  Therefore, a technology that prevents the game ball from popping out by providing a protrusion on the back of the design board (front decoration) that constitutes the start winning device and causing the game ball flowing into the start winning device to collide with the protrusion to weaken the momentum. Has been proposed (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2005-334207 (FIGS. 1-4, etc.)

  However, in the prior art described in Patent Document 1, since the game ball that has flowed into the start winning opening does not always collide with the protrusion, there is a high possibility that the game ball cannot be prevented from jumping out. In other words, since the identification given to the player remains bad, there is a problem that the decline of interest cannot be prevented.

  The present invention has been made in view of the above problems, and its purpose is to reliably prevent a game ball flowing from one wing member side from jumping out from the other wing member side, thereby reducing the interest. An object of the present invention is to provide a gaming machine winning device that can be prevented.

In order to solve the above problems, the invention described in claim 1 (means 1) includes a base plate that comes into contact with a game board surface, a design plate provided on the front side of the base plate, the base plate, and the design plate. A pair of blade members that can be switched between a closed state in which a game ball cannot pass and an open state in which the game ball can pass by rotating about an inner end as a fulcrum. A space on the back side of the board, in which the game balls can flow when the pair of blade members are in the open state, is defined in a region between the pair of blade members, and the rear surface of the base plate On the side, the gaming machine winning device is provided with a gaming ball detection means for detecting the gaming ball that flows into the space and passes through a winning path extending from the space to the rear of the gaming machine. , Below the gate disposed in the right area on the surface of the game board Disposed, the pair of blade members, the passage of the game ball to the gate can be switched to the open state as a trigger, between the inner ends of the pair of blade members, the front side of the gaming machine And having a slope that becomes lower as it goes from the start end located at the rear to the end located at the rear side of the gaming machine, guides the game ball flowing into the space along the slope and guides it to the game ball detection means side. A guide member is provided, and the height of the starting end of the slope is higher on the other blade member side than on one blade member side, and the left region side on the game board surface is higher than the right region side. The award-winning device for a gaming machine characterized by this is the gist.

  Therefore, according to the invention described in claim 1, even if the game ball that has flowed in from one wing member side proceeds from one wing member side to the other wing member side on the slope of the guide member, Since the starting end of the slope is higher on the other blade member side than on the one blade member side, the game ball is difficult to reach the other blade member over the other blade member side of the slope. As a result, it is possible to prevent the game ball from jumping out from the other blade member side, so that it is not necessary to betray the player's expectation for winning, and it is possible to prevent a decrease in interest.

  Here, as a winning device for gaming machines, a start winning device that gives a start condition of a symbol variation game triggered by a winning of a game ball, during a jackpot game that is given when the result of the symbol variation game becomes a big hit And a prize winning device that can be switched to an open state through which a game ball can pass.

The gist of the invention described in means 2 is that, in the above means 1, a protrusion is provided on the back surface of the design plate so as to be positioned above the guide member.

Therefore, according to the invention described in the means 2, even if the game ball that has flowed in from one wing member side proceeds toward the other wing member side, the game sphere is placed on the guide member after colliding with the protrusion. Since it falls, it becomes difficult to reach the other blade member side. As a result, it is possible to reliably prevent the game ball from jumping out from the other blade member side by both the guide member and the protrusion, and thus it is possible to reliably prevent a decrease in interest.

The invention described in means 3 is the above means 1 or 2, wherein the design plate is arranged on the front side of the base plate, covers at least the inner ends of the pair of blade members, and the pair of blades. A lower plate that is disposed below the member and connects the front plate and the base plate, and the guide member protrudes upward from the lower plate and is connected to the front plate, and an upper end surface is a part of the slope. A plurality of guide ribs that are arranged with a gap in the lateral direction of the gaming machine, the guide blade located on the one blade member side is more on the other blade member side than the starting end of the upper end surface The gist is that the starting end of the upper end surface of the guide rib located at is higher.

Therefore, according to the invention described in the means 3, it is assumed that the game ball that has flowed in from one blade member side proceeds from the guide rib located on one blade member side toward the guide rib located on the other blade member side. However, the guide rib located on the other blade member side is higher than the guide rib located on the other blade member side, so that the game ball is guided on the other blade member side. It becomes difficult to get over the rib and reach the other blade member. As a result, it is possible to more reliably prevent the game ball from jumping out from the other blade member side, and thus it is possible to more reliably prevent a decrease in interest. In addition, the game ball guided along the guide member flows down in a state where the lower end portion is fitted in the gap between the pair of adjacent guide ribs, and is guided to the game ball detecting means side. As a result, the game ball drops off from between a pair of adjacent guide ribs and does not easily reach the other blade member side, so that the game ball can be more reliably prevented from jumping out. Furthermore, since the guide rib is connected to both the front plate and the lower plate, the front plate and the lower plate can be reinforced by the guide rib. Moreover, since the guide rib protrudes from the lower plate and supports the game ball on the upper end surface side of the lower plate, when the inflowing game ball collides with the guide rib, the impact from the game ball is detected by the guide rib. And can be received both on the bottom plate. Therefore, the guide rib can be made strong against a collision of game balls.

  When a gate is arranged in the right region on the game board surface and the pair of blade members are switched to an open state triggered by the passage of the game ball to the gate, the player launches the game ball aiming at the gate (so-called right Strike). In this case, since the player launches the game ball at a high speed by turning the operation handle greatly to the right, the launch speed of the game ball is very high. Therefore, after passing the game ball to the gate, when the game ball is continuously made right-handed to win the game machine winning device, the released game ball remains in a strong momentum. Therefore, there is a high possibility that the game ball flowing in from one (right) blade member side will jump out from the other (left) blade member side.

Therefore, in the first aspect of the invention, the left region side on the game board surface on the slope of the guide member is set higher than the right region side on the game board surface on the slope. For this reason, even if the game ball that has flowed in from the right blade member side advances from the right region side to the left region side on the slope of the guide member, the game ball gets over the left region side of the slope and left It becomes difficult to reach the blade member. As a result, it is possible to prevent the game ball from jumping out from the left wing member side, so that it is not necessary to betray the player's expectation for winning, and it is possible to prevent a decrease in interest.

As described in detail above, according to the first aspect of the present invention, it is possible to reliably prevent the game ball flowing in from one wing member side from jumping out from the other wing member side, thereby preventing a decrease in interest. A winning device for a gaming machine that can be provided can be provided .

The effect design is a design showing 10 numbers from “0” to “9”.

  As shown in FIG. 2 and FIG. 4 to FIG. 7, an upper start winning port 51a and a lower start winning port 51b are formed at the lower position of the center accessory 50 on the gaming board surface 13a. A start winning device 51 which is “device” is arranged. Behind the start winning device 51, the upper start opening switch SE1 (see FIGS. 3, 5 to 8) for detecting the game ball A1 won in the upper start winning opening 51a and the lower start winning opening 51b are won. A lower start port switch SE2 (see FIGS. 3 and 5 to 8), which is a “game ball detecting means” for detecting the game ball A1, is provided. The start port switches SE1 and SE2 are turned on when a game ball A1 won in the start winning device 51 is detected, and a winning signal is output. On the other hand, the start port switches SE1 and SE2 are turned off when the game ball A1 is not detected, and no winning signal is output. When a winning signal is output, a special symbol variation game is performed by the special symbol display device 61, and an effect symbol variation game is performed by the effect symbol display device 60, and a predetermined number (three in this embodiment). ) Will be paid out.

  As shown in FIGS. 2, 4, and 5, the start winning device 51 is integrally configured with an ordinary electric accessory comprising a pair of blade members 91 a and 91 b. One blade member 91a is located on the right region side on the game board surface 13a, and the other blade member 91b is located on the left region side on the game board surface 13a. The pair of blade members 91a and 91b are closed so that the game ball A1 cannot pass and the game ball A1 can pass by the exciting action of the normal electric accessory solenoid SOL1 (see FIGS. 3, 5, and 8). It can be switched to the open state. In the present embodiment, the “closed state” refers to a state in which the lower start winning opening 51b is closed by closing the pair of blade members 91a and 91b. On the other hand, the “open state” means a state in which the game ball A1 can be awarded to the lower start winning opening 51b by opening the pair of blade members 91a and 91b.

  As shown in FIG. 2, a big prize device 53 is arranged below the start prize device 51 on the game board surface 13a. The special winning device 53 is provided with a special electric accessory comprising a special winning opening door 53a. The special winning opening door 53a can be switched between a closed state in which the gaming ball A1 cannot pass and an open state in which the gaming ball A1 can pass by the exciting action of the special winning solenoid SOL2 (see FIG. 3). . In the present embodiment, the “closed state” means a state in which the big prize opening door 53a is completely closed, and the “open state” means a state in which the big prize opening door 53a is completely opened. Further, a count switch SE3 (see FIG. 3) for detecting the winning game ball A1 is provided in the back of the big winning device 53. When the game ball A1 is detected by the count switch SE3, a predetermined number (15 in this embodiment) of payout balls is paid out.

  Further, a gate 54 having a function of detecting passage of the game ball A1 is provided on the right side of the center accessory 50. That is, the start winning device 51 described above is disposed below the gate 54. Note that the game nail 35 disposed on the right side of the center accessory 50 guides a part of the game ball A1 passing through the right side of the center accessory 50 to the gate 54. That is, the gate 54 is disposed in the right region on the game board surface 13a (specifically, on the flow path of the game ball A1 passing through the right side of the center accessory 50).

  Further, a gate switch SE4 (see FIG. 3) for detecting the passed game ball A1 is provided at the back of the gate. A random number (ordinary hit determination random number) is acquired when the game ball A1 passes through the gate 54 (when the game ball A1 is detected by the gate switch SE4), and the acquired random number is a predetermined random value. Based on the result of determining whether or not (ordinary hit determination value), the ordinary electric accessory solenoid SOL1 is driven. Such a determination (normal hit determination) switches the pair of blade members 91a and 91b of the ordinary electric accessory to the open state, so that the game ball A1 can easily win the lower start winning opening 51b.

  As shown in FIG. 2, a special symbol display device 61 having a visible display unit is disposed on the lower right side of the center accessory 50.

A symbol variation game is displayed, and as a result of the special symbol variation game, display results of jackpot and lose are displayed. For example, when the result of the special symbol variation game is a big hit, at the end of the special symbol variation game, symbols indicating ten different numbers “0” to “9” are displayed as the special symbols. On the other hand, when the result of the special symbol variation game is lost, at the end of the special symbol variation game, a symbol “-” indicating a loss is displayed as the special symbol.

  Furthermore, in this embodiment, the effect symbol change game by the effect symbol display device 60 is performed in accordance with the special symbol change game on the special symbol display device 61. Specifically, the effect symbol variation game is started almost simultaneously with the start of the special symbol variation game, and the result of the effect symbol variation game is displayed almost simultaneously with the end of the special symbol variation game (the result of the big hit or lose) is displayed. It is like that. In the present embodiment, the effect symbol variation game performed by the effect symbol display device 60 and the special symbol variation game performed by the special symbol display device 61 are referred to as a “variation game”.

(3) Electrical Configuration of Pachinko Machine 10 As shown in FIG. 3, the pachinko machine 10 includes a main control board 21, a general control board 22, a display control board 23, and an audio / lamp control board 24. An overall control board 22 is electrically connected to the main control board 21, and a display control board 23 and an audio / lamp control board 24 are electrically connected to the overall control board 22.

(3-1) Electrical configuration of main control board 21 The main control board 21 includes a main CPU 21a that controls the pachinko machine 10. An upper start port switch SE1, a lower start port switch SE2, a count switch SE3, and a gate switch SE4 are connected to the main CPU 21a. In addition, a special symbol display device 61, a normal electric accessory solenoid SOL1, and a special prize opening solenoid SOL2 are connected to the main CPU 21a.

  A main ROM (not shown) and a main RAM (not shown) are electrically connected to the main CPU 21a shown in FIG. The main CPU 21a stores various random numbers such as jackpot determination random numbers used for various lotteries related to special symbol variation games, random numbers for jackpot symbols, and various random numbers such as normal hit determination random numbers used for lotteries related to normal symbol variation games. The value is updated every predetermined period. The main CPU 21a sets the updated value in the random number storage area of the main RAM and rewrites the value before the update.

  The big hit determination random number is a random number used when determining whether or not the variable game is a big hit (when determining the big hit). The jackpot symbol random number is a random number used when determining a special symbol when the result of the variable game is a jackpot. The normal hit determination random number is a random number used when determining whether or not the normal symbol variation game is a win (during the normal hit determination).

  Next, various processes related to the variable game executed by the main CPU 21a shown in FIG. 3 (such as jackpot determination, jackpot symbol determination, loss symbol determination, etc.) will be described.

  First, the main CPU 21a determines whether or not a winning signal is input from the upper start port switch SE1 or the lower start port switch SE2. When it is determined that a winning signal has been input, the main CPU 21a performs control to execute a special symbol variation game. Specifically, the main CPU 21a obtains the value of the big hit symbol random number extracted by random number lottery and updated every predetermined period from the main RAM, and stores the obtained value in the random number storage area of the main RAM ( Remember. Further, the main CPU 21a acquires, from the main RAM, a value of a big hit determination random number extracted by a random number lottery and updated every predetermined period when the start winning condition is satisfied, and the acquired value is a random number of the main RAM. Store (store) in the storage area.

  Next, when the winning signal is input, the main CPU 21a shown in FIG. 3 determines whether or not the result of the special symbol variation game (variation game) is a big hit. More specifically, the main CPU 21a compares the jackpot determination random number stored in the random number storage area of the main RAM with the jackpot determination value stored in the main ROM immediately before the start of the special symbol variation game. Then, a jackpot determination (a jackpot lottery) for determining whether or not the special symbol variation game is successful is performed. In the present embodiment, the numerical values that can be taken by the jackpot determination random number are set to 0 to 599 (all 600 integers). Then, the main CPU 21a uses the two jackpot determination values among the numbers that can be taken by the jackpot determination random number, and determines the jackpot with the jackpot lottery probability being 2/600 (= 1/300).

  When the determination result of the big hit determination is negative (the value of the big hit determination random number does not match the big hit determination value), the main CPU 21a determines the loss. Then, the main CPU 21a determines the symbol “−” indicating a loss as a special symbol. Furthermore, the main CPU 21a stores data corresponding to the determined special symbol in the main RAM until the next special symbol variation game is performed.

  On the other hand, when the determination result of the big hit determination is affirmative (the value of the random number for big hit determination matches the big hit determination value), the main CPU 21a shown in FIG. 3 determines the big hit. When the jackpot determination is made, the main CPU 21a determines a special symbol indicating any one of “0” to “9” based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM. To do. Then, the main CPU 21a stores data corresponding to the determined special symbol in the main RAM until a process related to the next special symbol variation game is performed. Further, when the special symbol is determined, the main CPU 21a causes the special symbol display device 61 to start changing the special symbol.

  Further, the main CPU 21a determines whether or not to provide a variation time shortening state for shortening the variation time of the special symbol when the determination result by the jackpot determination is a big hit. Specifically, the main CPU 21a determines whether the value of the jackpot symbol random number stored in the random number storage area of the main RAM is any one of “1”, “3”, “5”, “7”, “9”. In some cases, it is determined to give the variable time reduction state. On the other hand, the main CPU 21a determines that the variable time shortening state is not given when the value of the jackpot symbol random number is “0”, “2”, “4”, “6”, “8”. .

  When the main CPU 21a shown in FIG. 3 determines that the variable time reduction state is to be provided, the main CPU 21a provides the variable time reduction state after the end of the big hit game. Note that the variation time reduction state is continued until the symbol variation display is executed a plurality of times (in this embodiment, 100 times), but until the next big hit game is started. It may be continued for a while.

(3-2) Electrical Configuration of Overall Control Board 22 As shown in FIG. 3, the overall control board 22 includes an overall control CPU 22a. The overall control CPU 22a includes an overall ROM (not shown) and an overall RAM (not shown). Abbreviation) is connected. Various information used for determining the game effect is temporarily stored (set) in the overall RAM.

  The overall control CPU 22a generates an effect symbol that is stopped and displayed on the effect symbol display device 60 at the end of the effect symbol variation game, based on various commands input from the main CPU 21a. Then, the overall control CPU 22a sends an instruction command for instructing the display control board 23 and the sound / lamp control board 24 to execute the game effect, and the display control CPU 23a of the display control board 23 and the sound / lamp control board 24 The lamp is output to the lamp control CPU 24a. As a result, the specific contents of the game effects executed by the display control board 23 and the sound / lamp control board 24 are comprehensively controlled by the overall control board 22.

(3-3) Electrical Configuration of Display Control Board 23 As shown in FIG. 3, the display control board 23 includes a display control CPU 23a. The display control CPU 23a includes a display ROM (not shown) and a display RAM (not shown). Abbreviation) is connected. The display ROM stores display effect data used when the effect symbol variation game is performed. The display effect data is information for the display control CPU 23a to control display contents (such as symbol variation) of the effect symbol display device 60. The display RAM temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  When an instruction command is input from the overall control CPU 22a, the display control CPU 23a converts the display effect data stored in the display ROM into a symbol signal and outputs it to the effect symbol display device 60. As a result, the effect symbol display device 60 can perform a predetermined display (such as an effect symbol variation game) based on the symbol signal.

(3-4) Electrical configuration of voice / lamp control board 24 As shown in FIG. 3, the voice / lamp control board 24 includes a voice / lamp control CPU 24a. A ROM (not shown) and a sound / lamp RAM (not shown) are connected.

The light effect data is information for the sound / lamp control CPU 24a to control the light emission output mode of the frame lamps 16a to 16c. The voice effect data is information for the voice / lamp control CPU 24a to control the voice output mode (sound effect type, language voice type, voice output time, etc.) of the speaker 17 (see FIG. 3). In the voice / lamp RAM, various information that is appropriately rewritten during the operation of the pachinko machine 10 is temporarily stored (set).

  When an instruction command is input from the overall control CPU 22a, the sound / lamp control CPU 24a converts the light effect data stored in the sound / lamp ROM into a light control signal and outputs the light control signal to the frame lamps 16a to 16c. As a result, the frame lamps 16a to 16c can perform a predetermined light emission operation (lighting, blinking, etc.) based on the light emission control signal. The sound / lamp control CPU 24 a converts sound effect data stored in the sound / lamp ROM into a sound signal and outputs the sound signal to the speaker 17. As a result, the speaker 17 can perform a predetermined output operation (sound output) based on the audio signal.

Further, an engagement piece 115 is provided in the vicinity of the arm shaft 112 a in the arm portion 111, and the engagement piece 115 is engaged with an engagement hole 105 provided in the solenoid pin 104. The solenoid pin 104 is attached to the tip of the plunger 102. As a result, the arm portion 111 moves in synchronization with the plunger 102.

  Therefore, when the ordinary electric accessory solenoid SOL1 is excited, the arm portion 111 rotates as the plunger 102 and the solenoid pin 104 move rearward. At this time, as the connection recesses 114a and 114b of the arm portion 111 move upward, the connection pieces 93a and 93b held by the connection recesses 114a and 114b also move upward. As a result, both the blade members 91a and 91b rotate in a direction in which the tip portions are separated from each other, and are in an open state (see FIGS. 4, 5, and 11). On the other hand, when the ordinary electric accessory solenoid SOL1 is in a non-excited state, the urging force of the coil spring 103 causes the arm portion 111 to rotate as the plunger 102 and the solenoid pin 104 move forward. At this time, as the connection recesses 114a and 114b move downward, the connection pieces 93a and 93b also move downward. As a result, both the blade members 91a and 91b rotate in a direction in which the tip portions approach each other, and are in a closed state.

Specifically, the height of the terminal end S2 of the upper end surface of the guide rib 142a is equal to the height of the terminal end S4 of the upper end surface of the guide rib 142b.

  As shown in FIGS. 5 to 7, on the rear surface 71 b side of the base plate 71, the game ball A <b> 1 that flows into the space A <b> 2 and passes through the winning path R <b> 1 extending from the space A <b> 2 to the rear of the pachinko machine 10 is detected. A side start port switch SE2 is provided. More specifically, the lower start port switch SE2 has one end inserted into the housing on the front case 121 side and the other end inserted into the housing on the rear case 122 side. By engaging the rear case 122 with the rear case 122, the rear case 122 is held between the front case 121 and the rear case 122. In addition, the front case 121 is positioned in front of the lower start port switch SE2 and is connected to the guide member 141 (specifically, the terminal ends S2 and S4 of the slope 151). Is formed. The lower start opening ball passage 124 has a slope that becomes lower from the start end located on the guide member 141 side toward the end located on the lower start opening switch SE2. The lower start opening ball passage 124 passes through the lower start winning opening 51b and flows into the space A2, and guides the game ball A1 guided by the guide member 141 toward the lower start opening switch SE2. ing. The game ball A1 guided to the lower start port switch SE2 side passes through the lower start port switch SE2 and is then discharged to the outside of the start winning device 51.

  Next, a game procedure will be described.

  (A) First, the player launches (so-called left-handed) the game ball A1 aiming at the upper start winning opening 51a of the start winning device 51. When the game ball A1 wins the upper start winning opening 51a, a special symbol variation game for varying the special symbol is started, and an effect symbol variation game for varying the effect symbol is started. These variable games are repeated each time the game ball A1 wins the upper start winning opening 51a.

  (B) By the way, in a predetermined variation game, the determination result of the big hit determination may be a big hit, for example. In this case, a big hit game in which the big prize opening door 53a of the big prize winning device 53 is opened is given. In addition, the player launches (so-called right-handed) the game ball A1 along a route R2 (see FIG. 2) from the terminal portion of the launch route 33 to the prize winning device 53. Then, when the game ball A1 that has entered the special winning device 53 passes the count switch SE3, the payout of the prize ball is performed.

  (C) Further, the main CPU 21a determines whether or not to provide a variable time reduction state. Specifically, the main CPU 21a is, based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM, whether the special symbol is a specific symbol that triggers the start of the variable time reduction state, It is determined whether the symbol is a non-specific symbol that does not trigger a change time reduction state. When it is determined that the special symbol is a non-specific symbol, the main CPU 21a determines that the variation time reduction state is not given. On the other hand, when it is determined that the special symbol is the specific symbol, the main CPU 21a determines to provide the variable time reduction state. In this case, the variation time reduction state is given after the big hit game.

  (D) Further, when a game ball that has passed through the gate 54 (see FIG. 2) is detected by the gate switch SE4 when the big hit game is being performed and the variation time reduction state is not given, the main CPU 21a The normal hit determination in the normal symbol variation game is performed by comparing the normal hit determination random number value read from the RAM with the normal hit determination value stored in the main ROM. In the present embodiment, the numerical values that can be taken by the random numbers for ordinary hit determination are 0 to 240 (a total of 241 integers). Then, the main CPU 21a performs the normal hit determination by using 50 normal hit determination values determined in advance from the numerical values that the normal hit determination random numbers can take, and the winning lottery probability is 50/241. The main CPU 21a also makes a normal hit determination when the game ball that has passed through the gate 54 is detected by the gate switch SE4 even when the variation time reduction state is given after the big hit game. In this case, the main CPU 21a performs the normal hit determination by using 240 normal hit determination values from among the numerical values that can be taken by the normal hit determination random number, and the winning lottery probability is 240/241. That is, the winning lottery probability during the variation time shortened state is larger than the winning lottery probability before the varying time shortened state.

  If the determination result of the normal hit determination is negative (the value of the random number for normal hit determination does not match the normal hit determination value), the pair of blade members 91a, 91 provided in the start winning device 51 is kept closed. In this case, the player switches to left-handed and plays the game (A) when the big hit game ends. On the other hand, when the determination result of the normal hit determination is affirmative (the value of the normal hit determination random number matches the normal hit determination value), the main CPU 21a performs control to drive the normal electric accessory solenoid SOL1. In this case, since the pair of blade members 91a and 91b included in the start winning device 51 are switched to the open state, the player launches the game ball A1 aiming at the lower start winning port 51b of the start winning device 51 (right-handed). )

  (E) When the player strikes the game ball A1 rightward aiming at the lower start winning opening 51b, the game ball A1 is on the blade member 91a side on the right region side (left side in FIG. 11) of the game board surface 13a. There is a high possibility of flowing into the space A2. At this time, the game ball A1 that has flowed into the space A2 may travel toward the blade member 91b side on the left region side (right side in FIG. 11) of the game board surface 13a, but the game ball A1 has a protrusion 131. Since it falls on the guide member 141 after colliding, it becomes difficult to reach the blade member 91b side (see FIG. 11). As a result, the game ball A1 is prevented from jumping out from the blade member 91b side.

  Moreover, the guide rib 142b located on the blade member 91b side has a higher starting end of the inclined surface 151 than the guide rib 142a located on the blade member 91a side (see FIG. 11). For this reason, even if the game ball A1 flowing into the space A1 travels from one guide rib 142a toward the other guide rib 142b, the game ball A1 does not easily reach the blade member 91b over the guide rib 142b. Become. As a result, it is possible to more reliably prevent the game ball A1 from jumping out from the blade member 91b side. The game ball A1 guided along the guide member 141 flows down with the lower end fitted in the gap between the pair of guide ribs 142a and 142b, and is guided to the lower starter switch SE2 side. When the game ball A1 is detected by the lower start port switch SE2, a special symbol variation game and an effect symbol variation game can be newly started.

  (F) Thereafter, the player switches to left-handed and plays a game (A) when the variable time shortening state ends.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 of the present embodiment, the game ball A1 that has flowed in from one wing member 91a side is guided from the guide rib 142a located on the one wing member 91a side to the other wing member 91b side. Even if it advances toward 142b, the other guide rib 142b has a higher starting end than the one guide rib 142a, so that the game ball A1 gets over the other guide rib 142b and the other blade member 91b. It becomes difficult to reach. Moreover, even if the game ball A1 advances toward the other blade member 91b, the game ball A1 falls on the guide member 141 after colliding with the protrusion 131, and therefore reaches the other blade member 91b. It becomes difficult. As a result, since the game ball A1 can be prevented from jumping out from the other blade member 91b side, it is not necessary to betray the player's expectation for winning, and it is possible to prevent a decrease in interest.

  (2) In this embodiment, since the guide ribs 142a and 142b are connected to both the front plate 82 and the lower plate 83, the front plate 82 and the lower plate 83 can be reinforced by the guide ribs 142a and 142b. Moreover, since the guide ribs 142a and 142b protrude from the lower plate 83 and support the game ball A1 on the upper end surface side of the lower plate 83, when the inflowing game ball A1 collides with the guide ribs 142a and 142b, Can receive an impact from the game ball A1 by both the guide ribs 142a and 142b and the lower plate 83. Therefore, the guide ribs 142a and 142b can be made strong against the collision of the game ball A1.

  In addition, you may change this embodiment as follows.

  In the above embodiment, the start end S3 of the upper end surface of the guide rib 142b located on the other blade member 91b side is higher than the start end S1 of the upper end surface of the guide rib 142a located on the one blade member 91a side. However, the start end S1 may be higher than the start end S3.

  In the above embodiment, the guide member 141 is constituted by the two guide ribs 142a and 142b. However, the guide member may be constituted by three or more guide ribs. Also, as shown in FIG. 12, the guide member 161 is configured by one guide rib 162, and the slope 164 on the other blade member 163b side is higher than the height of the starting end S5 of the slope 164 on the one blade member 163a side. The height of the starting end S6 may be increased.

  In the above embodiment, the start winning device 51 is used as the “awarding device for gaming machines”. However, a big prize device including a pair of blade members that are open during the big hit game may be used as the “game machine prize device”.

  In the above embodiment, the start winning device 51 and the big winning device 53 are disposed below the center accessory 50 on the game board surface 13a, but the starting winning device 51 and the big winning device 53 are the game board surface. You may arrange | position in other places, such as the lower right position of the center accessory 50 on 13a.
