[Functional configuration of game control unit]
Next, the functional configuration of the game control unit 200 will be described.
FIG. 5 is a block diagram showing a functional configuration of the game control unit 200. As shown in FIG. 5, the game control unit 200 includes a random number acquisition unit 231, a normal symbol determination unit 232, a special symbol variation control unit 233, and a special symbol determination unit 234 as functional units that execute various lottery processes. And a normal symbol fluctuation control unit 236.
In addition, the game control unit 200 includes a variation pattern selection unit 235 as a functional unit that executes processing associated with special symbol variation.
Furthermore, the game control unit 200 is a function unit that executes data processing related to operation control of various types of objects and prize balls, etc. As a function unit, a prize winning opening operation control unit 237, an electric tulip operation control unit 238, and a prize ball processing unit 239 are provided. And an output control unit 240 and a random number control unit 241.

The random number acquisition unit 231 acquires a random number value used for the special symbol lottery and a random value used for the normal symbol lottery. In the case of a random number value used for the special symbol lottery, specifically, on the condition that a game ball has won a prize at the first starting port 121 or the second starting port 122, a numerical value within a predetermined range for each type of random number. One numerical value (random number value) is selected (obtained) from the inside. The acquired random number value is used for determination by the special symbol determination unit 234. As will be described in detail later, the random numbers used in the special symbol lottery include a jackpot random number indicating whether or not the jackpot, a symbol random number indicating the type of jackpot, a variation pattern random number, a reach random number, and the like.
Further, in the case of a random number value used in the normal symbol lottery, specifically, one numerical value (random number value) is selected (obtained) from a predetermined range of values on the condition that the game ball has passed through the gate 124. ) The acquired random number value is used for determination by the normal symbol determination unit 232. In addition, as a random number used for the normal symbol lottery, a symbol random number indicating a winning type, a variation pattern random number, or the like may be set in addition to a winning random number indicating whether or not the winning is made.
When the special symbol lottery is performed, the special symbol fluctuation control unit 233 controls the fluctuation of the special symbol in the first special symbol indicator 221 or the second special symbol indicator 222 according to the lottery result.

  The special symbol determination unit 234 uses a random number table at the time of starting the variation of the special symbol, and the lottery result of the special symbol lottery is “whether it is a big hit”, “a type of big hit when winning a big winner”, “winning a big winner” It is determined whether or not it is a small hit or not when not. That is, the random number acquisition unit 231 acquires a random number value related to a special symbol when the first starting port switch 211 or the second starting port switch 212 serving as a detection unit detects passage of a game ball, and determines a special symbol. The unit 234 determines based on the acquired random number value whether or not to play a special game (such as a big hit game) advantageous to the player. The special symbol lottery (big hit lottery) described above refers to processing in the random number acquisition unit 231 and the special symbol determination unit 234.

  Here, the “hit” is divided into a plurality of types according to the gaming state that occurs after the end of the jackpot game. Specifically, the type of jackpot is determined depending on the combination of the short-time state or the short-time state and the high-probability state or the low-probability state. That is, the types of jackpots based on the gaming state that occurs after the end of the jackpot game are the jackpots that become the short game state with a high probability after the jackpot game ends (hereinafter, the jackpot of the short game state with a high probability), the short game state with a low probability Jackpot to become a jackpot (hereinafter referred to as a jackpot of a low probability short game state), a jackpot to be a high probability short gameless state (hereinafter a jackpot of a high probability short gameless state), a jackpot to become a low probability short gameless state (hereinafter low) There is a possibility of a jackpot of probable short gameless state). Each of these jackpots is associated with an individual special symbol, and the type of jackpot is determined according to the type of special symbol won in the special symbol lottery.

  In addition, the “bonanza” may be divided into a jackpot that can be expected to pay out a large amount of gaming balls for a long time, and a jackpot that can hardly be expected to pay out gaming balls because the jackpot game time is short. The former is called “long hit” and the latter is called “short hit”. For example, in “long win”, a round that is maintained until the open state of the grand prize opening 125 satisfies a predetermined condition (for example, 29.5 seconds have passed or 10 game balls have been won) is repeated a predetermined number of times (for example, 15 times). It is. In the “short win”, a round in which the special winning opening 125 is opened for a certain time (for example, 0.1 second) is repeated a predetermined number of times (for example, 15 times).

In addition, in the case of “small winning” when the big winning is not won, for example, a small winning game is performed in which the big winning opening 125 is opened for a predetermined number of times (for example, 15 times) for 0.1 seconds. At the time of winning the small hit, the game state before the small win is continued even after the small hit game is completed. That is, when the game state at the time of winning the small hit is the high probability short game state, the high probability short time gaming state is continued even after the small hit game ends, and the gaming state does not shift. Similarly, when the game state at the time of winning the small hit is the low probability short-time non-game state, the low-probability short short no-game state is continued even after the small hit game ends, and the game state does not shift.
Further, “small hit” is a kind of “out of game”, and none of the above gaming states that are advantageous to the player is set.

The variation pattern selection unit 235 selects a variation pattern (variation time) of a special symbol displayed on the first special symbol display 221 or the second special symbol display 222. Specifically, the variation pattern selection unit 235 determines the variation pattern based on the determination result whether or not to play the jackpot game, the determination result whether or not to reach and the like. Then, based on the variation pattern selected by the variation pattern selection unit 235, the special symbol variation control unit 233 controls the variation of the special symbol. Details of operations of the fluctuation pattern selection unit 235 and the special symbol fluctuation control unit 233 will be described later.
Here, “reach” is an effect for causing a player to expect a big hit in a decorative pattern to be described later.

The normal symbol determination unit 232 determines whether the lottery result of the normal symbol is “winning” or not by using a random number table at the start of the variation of the normal symbol. That is, the normal symbol determination unit 232 determines whether or not to perform an auxiliary game that opens and closes the electric tulip 123 based on the random number value for normal symbol lottery acquired by the random number acquisition unit 231. When a plurality of types of winning are set in the normal symbol lottery, the normal symbol determining unit 232 determines “winning type” when the determination result is winning. The normal symbol lottery is a process performed by the random number acquisition unit 231 and the normal symbol determination unit 232.
When the normal symbol lottery is performed, the normal symbol fluctuation control unit 236 controls the fluctuation of the normal symbol by the normal symbol display unit 223 according to the lottery result.
The electric tulip movement control unit 238 opens the electric tulip 123 for a predetermined time and a predetermined number of times when the normal symbol determination unit 232 determines “winning” in the normal symbol lottery, and a game ball is placed at the second start port 122. Generate a state that makes it easy to win. Further, when it is determined as “displacement”, such an open state of the electric tulip 123 is not generated.

When the special symbol determination unit 234 determines that it is a “big hit” in the special symbol lottery, the big winning mouth operation control unit 237 uses the operation pattern specified based on the type of the winning jackpot as the jackpot game. The opening operation of 125 is controlled. Also, the special winning opening operation control unit 237 opens the special winning opening 125 for a specified time and a specified number of times as a small winning game when the special symbol determining unit 234 determines “small hit” in the special symbol lottery. .
The prize ball processing unit 239 sets commands for controlling the number of prizes received for various types of winning-related items and lottery, and for controlling the payout of prize balls according to the prizes.
The output control unit 240 controls the output of control commands from the game control unit 200 to the effect control unit 300 and the payout control unit 330.
The random number control unit 241 updates various random number values that the random number acquisition unit 231 acquires at a predetermined timing.

[Basic operation of gaming machine]
Next, the basic operation of the pachinko gaming machine 100 will be described.
When the power is turned on, the game control unit 200 of the pachinko gaming machine 100 performs initialization and initial setting of various devices as a basic process at the time of activation. And after performing a basic process, the game control part 200 repeatedly performs the main control process which is a series of processes regarding progress of a game. In addition, when the power is shut off, the game control unit 200 executes a series of power-off processing.

FIG. 6 is a flowchart showing the basic processing performed by the game control unit 200.
When the power of the pachinko gaming machine 100 is turned on, the game control unit 200 first permits access to the RAM 203 (see FIG. 3) (step (hereinafter, “step” will be referred to as “S”) 601). Then, the game control unit 200 determines whether or not a RAM clear switch for clearing the RAM 203 is ON (S602).
When the RAM clear switch is OFF (No in S602), the game control unit 200 next determines whether or not the backup flag related to the operation at the time of power-off is ON (S603).
If the backup flag is ON (Yes in S603), the game control unit 200 next determines whether the checksum created when the power is turned off is normal (S604).
If the checksum is normal (Yes in S604), the game control unit 200 next executes a return process (S605). In this return process, the game control unit 200 performs setting of the sub-control means such as the effect control unit 300 accompanying the return from the state where the power is cut off. Specifically, the game control unit 200 determines the gaming state of the pachinko gaming machine 100 when the power is cut off (whether it is a big hit game, either a high probability state or a low probability state, a short time state or a short time state) The command for setting the sub-control means is output to the effect control unit 300 so that any one of them is reflected. In this return process, the game control unit 200 turns off the backup flag.

  On the other hand, if the RAM clear switch is ON (Yes in S602), the backup flag is OFF (No in S603), and the checksum is abnormal (No in S604), then the game control unit 200 is initialized. As processing, the stored contents of the RAM 203 are cleared (S606), and the work area of the RAM 203 is set (S607). Then, the game control unit 200 outputs a command for setting (initializing) the sub control means to the effect control unit 300, and sets the sub board (sub control means) (S608). The setting of the sub board includes clearing the RAM 303, RAM 313, and RAM 323 mounted on each sub board.

After the return process (see S605) is completed or after the setting of the sub-board (see S608) is completed, the game control unit 200 sets various counters and timers used for game control (S609). Then, the game control unit 200 determines whether or not the interrupt permission (S610), the interrupt prohibition (S611), the symbol random number control process (S612), the initial value random number update process (S613), and the power cutoff flag are ON. (S614) is repeatedly executed as a loop process.
Here, interrupt enable (S610) and interrupt disable (S611) are provided to enable execution of interrupt processing during execution of the loop processing (S610 to S614). In the present embodiment, main control processing in game control is executed by this interrupt processing. Details of the main control process will be described later.
In the symbol random number control process (S612), the game control unit 200 updates the variation pattern random number used in the special symbol lottery.
In the initial value random number update process (S613), the game control unit 200 updates initial values of various random values used in the game control.
In the determination of the power cut-off flag, if the power cut-off flag is OFF (No in S614), the power of the pachinko gaming machine 100 is not cut off, and the game control unit 200 performs main control by interruption together with the loop processing (S610 to S614). Repeat the process. On the other hand, when the power shut-off flag is ON (Yes in S614), the game control unit 200 starts a process for shutting off the power of the pachinko gaming machine 100 (power shut-off process).

FIG. 7 is a flowchart showing the operation of power-off processing performed by the game control unit 200.
In the power-off process, the game control unit 200 first clears the setting of the output port for performing various outputs (S701). Next, the game control unit 200 creates a checksum and stores it in the RAM 203 (S702). Next, the game control unit 200 sets the backup flag to ON (S703), prohibits access to the RAM 203 (S704), and shifts to an infinite loop.

[Main control processing of gaming machines]
Next, main control processing of the pachinko gaming machine 100 will be described.
In the main control process, the game control unit 200 controls the game in the pachinko gaming machine 100, instructs the effect control unit 300, which is a sub-control means, to control the effect, and gives a prize ball to the payout control unit 330. Instructs payout control.

FIG. 8 is a flowchart showing main control processing of the game control unit 200.
The main control process includes a series of processes in game control, and is repeatedly executed every predetermined time (for example, 4 milliseconds). In the present embodiment, the game control unit 200 generates an interrupt every predetermined time set in advance, and when the interrupt is permitted in the loop process shown in FIG. 6 (see S610), the main control is performed as the interrupt process. Execute the process. As shown in FIG. 8, in the main control process, a random number update process, a switch process, a symbol process, an electric accessory process, a prize ball process, and an output process are sequentially executed (S801 to S806).

  In the random number update process (S801), the game control unit 200 calls a function (subroutine) of the random number control unit 241, and updates various random number values used in the game control by the game control unit 200. Details of the setting of the random number and the update of the random value will be described later.

As the switch process (S802), a start port switch process and a gate switch process are performed.
In the start port switch process, the game control unit 200 calls the function (subroutine) of the random number acquisition unit 231, monitors the states of the first start port switch 211 and the second start port switch 212 in FIG. If this happens, a special symbol lottery process is executed. In addition, as will be described in detail later, when pre-determination processing is performed in the first start port switch 211 and the second start port switch 212, each function (subroutine) of the special symbol determination unit 234 and the variation pattern selection unit 235 is called, Execute processing for pre-determination.
In the gate switch process, the game control unit 200 calls the function (subroutine) of the random number acquisition unit 231 to monitor the state of the gate switch 214 in FIG. 3, and when the switch is turned on, for the normal symbol lottery. Execute the process.
The detailed contents of these switch processes will be described later.

As the symbol processing (S803), special symbol processing and normal symbol processing are performed.
In the special symbol process, the game control unit 200 calls the functions (subroutines) of the special symbol variation control unit 233, the special symbol determination unit 234, and the variation pattern selection unit 235, and executes the special symbol variation and the process associated with this symbol variation. To do.
In the normal symbol process, the game control unit 200 calls the functions (subroutines) of the normal symbol determination unit 232 and the normal symbol variation control unit 236, and executes the normal symbol variation and the process associated with this symbol variation.
The detailed contents of these symbol processes will be described later.

As the electric accessory process (S804), a big prize opening process and an electric tulip process are performed.
In the special prize opening process, the game control unit 200 calls a function (subroutine) of the special prize opening operation control unit 237 and controls the opening operation of the special prize opening 125 that is a special electric accessory based on a predetermined condition.
In the electric tulip process, the game control unit 200 calls the function (subroutine) of the electric tulip operation control unit 238 and controls the opening operation of the electric tulip 123 that is a normal electric accessory based on a predetermined condition.
The detailed contents of these electric accessory processing will be described later.

  In the prize ball processing (S805), the game control unit 200 calls a function (subroutine) of the prize ball processing unit 239, and sets a command for controlling the number of winning prizes and a control for paying out prize balls according to the winning prize.

  In the output process (S806), the game control unit 200 calls a function (subroutine) of the output control unit 240, outputs a command for effect control to the effect control unit 300, and sends a command for payout control to the payout control unit 330. Output. The effect control command is generated in each process from S802 to S804, and stored (set) in the control command storage area provided in the RAM 203. The payout control command is generated in the processing of S805 and stored (set) in the control command storage area provided in the RAM 203. A storage area is set in the RAM 203 for each type of control command.

  The output control unit 240 sequentially checks the storage area of each control command in the RAM 203, and if the control command is stored in each storage area (that is, the control command is generated in the processing of S802 to S805). The control command is read out and output to the output destination (the effect control unit 300 or the payout control unit 330).

  In the present embodiment, as shown in FIG. 8, output processing is performed at the end of a series of main control processing. That is, the command generated in each process of S802 to S805 by the above functions as the first processing means is stored in a corresponding storage area of the RAM 203 in each process. After these processes, the output control unit 240 as a second processing unit collectively outputs the commands generated in each process accumulated in the storage area of the RAM 203. In other words, in this embodiment, when the main control process is executed for one cycle, the command generated in the execution of the one cycle is output after the last command generation in the execution of the one cycle is performed.

[Modified example of basic operation of gaming machine]
In the operation example described with reference to FIGS. 6 to 8, the interrupt is permitted in the loop process portion of the basic process, and the main control process including a series of processes is executed as the interrupt process. However, the main control process only needs to be configured to be repeatedly executed at regular intervals, and the specific implementation means (execution procedure) is not limited to the examples illustrated in FIGS. For example, the main control process may be incorporated in a series of operations of the basic process, the elapsed time may be measured at a predetermined timing, and the process may return to the main control process every predetermined time (for example, 4 milliseconds). If the main control process is incorporated into the series of operations of the basic process, an interrupt is generated at regular intervals as in the operation described with reference to FIGS. It may be configured to return to the main control process incorporated in the basic process.

  When a command generated by basic processing is output, in principle, every time a command is generated, the command is stored in the command storage area of the RAM 203, and the function of the output control unit 240 as the second processing means is called. Output. Unlike the main control process related to the progress of the game, the basic process is a special process such as an initial operation performed only when the power is turned on. In addition, since the processing procedure may vary depending on the branching based on conditions such as the state of the pachinko gaming machine 100 when the power is turned on, the generated command is promptly output so that there is no omission in the output processing. It is processing. In addition, when a command is continuously generated by a plurality of related processes, a process procedure for storing a plurality of commands in the command storage area of the RAM 203 and outputting them in response to a specific process request is adopted. May be.

[Random number update processing by game control unit]
A random number value as determination information used for various types of lotteries in game control such as special symbol lottery is counted by a counter, and a random number update process (S801) of the main control process shown in FIG. 8 starts from a predetermined initial value. Each time it is done, it is incremented by one. Then, the value at the time when each lottery is performed is acquired by the start port switch process and the gate switch process, and is used in the special symbol process and the normal symbol process. This random number counter is an infinite loop counter, and after the counted random number reaches the set maximum random number, it returns to the initial value again. In addition, since the random number update process is performed at regular intervals, if the initial value of each random number is specified, the winning value may be estimated based on the update interval and the initial value information. Therefore, after returning from the main control process to the basic process shown in FIG. 6, in the initial value random number update process of S613, the initial value of each random number is randomly changed.

[About the game board main body 400 of the game board 110]
The game board 110 according to the present embodiment has a game board main body 400. The game board main body 400 according to the present embodiment is not a veneer (plywood, wood) but a resin-made plate-like member that transmits light, and is a transparent game board. More specifically, the game board main body 400 is formed integrally with a concavo-convex shape or a notch shape by molding, and is made of polycarbonate (PC). That is, the gaming board main body 400 according to the present embodiment can omit the step of cutting the concavo-convex shape or notch shape, and for this reason, the end surface of the concavo-convex shape or notch shape is polished glass. Not formed.

It is conceivable that the game board main body 400 according to the present embodiment is also applied to the case where an uneven plate shape or a cutout shape is formed by cutting an acrylic plate material as a material. In this case, the concavo-convex shape or the notch-shaped end surface is formed in a polished glass shape.
It is also conceivable to apply the game board main body 400 according to the present embodiment to a case where the resin members are bonded to each other with an adhesive.

Next, the configuration of the game board main body 400 will be described.
9-2 and FIG. 9-3 are diagrams illustrating the configuration of the game board main body 400. 9A is a front view, and FIG. 9B is a bottom view. FIG. 9-3 is a rear view.
As shown in FIG. 9-2 and FIG. 9-3, the game board main body 400 has a cutout shape for attaching various accessories and the like. For example, the game board main body 400 has an opening 401 for attaching a center ornament (not shown), an opening 402 for attaching the first starting port 121 and the second starting port 122, and an opening for attaching the grand prize winning port 125. 403 etc. are formed. These openings 401, 402, 403 penetrate from the front surface 400a of the game board main body 400 to the rear surface 400b.

  The front surface 400a of the game board main body 400 forms the game area 111 of the game board 110, and is formed substantially flat (see FIG. 9-2). On the other hand, the rear surface 400b of the game board main body 400 is formed in an uneven shape (see FIG. 9-3).

  More specifically, the game board main body 400 includes an edge rib 407 extending along the entire periphery along the edge. The edge rib 407 is formed so as to stand rearward from the front surface 400a. In other words, the edge rib 407 protrudes in the thickness direction of the game board main body 400. By adopting such a structure including the edge rib 407, the rigidity of the game board main body 400 is increased. In addition, it is possible to improve workability by using the edge rib 407 when attaching components such as various kinds of accessories to the game board main body 400. Further, when attaching the game board 110 to the game board holding frame (not shown), it is possible for the operator to improve workability by placing a finger on the edge rib 407.

Thus, the thickness T of the game board main body 400 is ensured by forming the resin game board main body 400. The thickness T here refers to a separation distance between the front surface 400a and the rear surface 400b of the game board main body 400.
The thickness T of the resin game board body 400 is the same as the thickness of the veneer game board and is 19 mm. For this reason, in the present embodiment, the frame member 150, more specifically, the game board holding frame 22 can be shared.

As shown in FIG. 9-3, the portion 405 of the rear surface 400b corresponding to the game area 111 (see FIG. 1) is formed into a plate thickness t1 by hollowing out the rear surface 400b side, and the other portion of the rear surface 400b. 406 is a plate thickness t2 (t2 <t1 <T). That is, the edge rib 407 is formed at the edge of the game board main body 400, and the thickness of the portion surrounded by the edge rib 407 is reduced by denting the rear surface 400b side of the portion surrounded by the edge rib 407. Yes. For this reason, in this embodiment, it is possible to reduce the weight of the game board main body 400 while ensuring the necessary strength of the game board main body 400.
Further, by providing the portion 405 of the game board main body 400 formed with the plate thickness t1, various kinds of accessories attached to the game board main body 400 are positioned as close to the front surface 400a as possible. For this reason, it is possible to secure a wider space on the rear surface 400b of the game board main body 400, and it is possible to relax design conditions for various mechanical components and the like.
The portion 405 of the rear surface 400b employs a plate thickness t1 that is thicker than the plate thickness t2 of the portion 406 of the rear surface 400b other than that in order to secure a thickness necessary for attaching the game nail.

[Configuration of Guiding Unit 420]
FIG. 10 is an enlarged view of the guidance unit 420 in the game board 110. 11A is an exploded perspective view of the guidance unit 420, and FIG. 11B is a diagram illustrating the guidance unit 420 as viewed from the front side. FIG. 12 is a diagram illustrating a state where the cover member 422 of the guidance unit 420 illustrated in FIG. 11-2 is removed. FIG. 13 is a diagram illustrating a state in which the guidance unit 420 is viewed from the back side. FIG. 14 is a diagram illustrating a state in which the base of the guidance unit 420 illustrated in FIG. 13 is removed.

  As illustrated in FIGS. 11A, 11B, and 13, the guide unit 420 includes a base 421, a cover member 422, and a rod-like member 423 disposed between the base 421 and the cover member 422. 11, 11-2, and 12, one end of the rod-like member 423 is embedded in the base 421, and the other end is embedded in the cover member 422 as shown in FIGS. 13 and 14. It is. As shown in FIGS. 13 and 14, the embedding portion is formed with a raised portion for securing the amount of embedding of the rod-shaped member 423.

  Further, as shown in FIGS. 9-4 and 10, the rod-like member 423 is arranged to be inclined toward the center at the lower part of the guidance unit 420 in a state where the guidance unit 420 is attached to the game board main body 400. Be placed. As will be described in detail later, the guidance unit 420 is configured such that game balls can enter from the left and right ends. Therefore, inside the guidance unit 420, the game ball rolls along the slope on the rod-like member 423 and is guided to the center.

  As shown in FIG. 12, the base portion 421 has a plate-like edge portion 424 protruding around. The edge portion 424 is provided with several screw holes, and the guide unit 420 is attached to the game board main body 400 by screws. As shown in FIGS. 9-4 to 12, a notch 424a is formed in the edge 424 at a position corresponding to the through hole 121a when the guide unit 420 is attached to the game board main body 400. Thus, the game ball that has gone out of the guidance unit 420 from a specific position is not prevented from winning the first start port 121. The base portion 421 has a wall portion 425 that rises from the base portion 421 on the upper edge portion of the base portion 421 when attached to the game board main body 400. With the wall portion 425, the upper side of the guide unit 420 is closed in a state where the base portion 421 and the cover member 422 are combined.

  As shown in FIG. 12, the base 421 has a protruding portion 426 that rises from the base 421 at the left end. The upper surface of the protrusion 426 (the surface positioned on the upper side when the guidance unit 420 is attached to the game board body 400) has entered from the end of the guidance unit 420 as shown in FIGS. The guide surface 427 guides the game ball. Further, the protrusion 426 and the rod-shaped member 423 are provided so that the guide surface 427 and the rod-shaped member 423 have a step. Further, the wall portion 425 of the base portion 421 has a convex piece 428 extending downward at a position facing the end portion of the guide surface 427 of the protruding portion 426.

  As illustrated in FIGS. 11A, 11B, and 13, the cover member 422 is attached to the base portion 421 with the rod-shaped member 423 interposed therebetween, thereby guiding the game ball inside the guide unit 420. Construct a taxiway. In addition, with the cover member 422 attached to the base 421, the left end and the right end of the guide unit 420 are opened so that a game ball can enter. As shown in FIG. 14, the end of the cover member 422 that is not embedded in the base 421 of the rod-shaped member 423 is embedded. Therefore, the cover member 422 can be grasped as a connecting member that connects and fixes the end of the rod-like member 423. Further, the cover member 422 and the base portion 421 can be grasped as a cover member that fixes both ends of the rod-shaped member 423 and covers the path of the game ball formed by the arrangement of the rod-shaped members 423. Further, the cover member 422 is formed of a member having translucency. Thereby, the player can visually recognize how the game ball is guided inside the guidance unit 420.

  As shown in FIG. 12 and FIG. 14, the rod-shaped members 423 are arranged on the left side of the guide unit 420 (the right side because FIG. 14 is viewed from the back side) and the center part of the guide unit 420. It is divided into a second array part 423b arranged at a wide interval and a third array part 423c arranged on the right side of the guide unit 420 (left side because FIG. 14 is a view seen from the back side). In the first arrangement portion 423a, the rod-like members 423 are arranged in such a manner that the guidance unit 420 is attached to the game board main body 400 and is inclined downward from the left to the right. In the third arrangement portion 423c, the rod-like members 423 are arranged so as to be inclined so as to be lowered from the right to the left in a state where the guide unit 420 is attached to the game board main body 400. And the 2nd arrangement part 423b is set as a lower position as a whole compared with the 1st arrangement part 423a and the 3rd arrangement part 423c. Accordingly, the game balls that have entered the inside of the guiding unit 420 are guided toward the second array portion 423b by the inclination of the first array portion 423a and the third array portion 423c.

As shown in FIGS. 12 and 14, the first array portion 423 a has a portion where the rod-like members 423 are arranged at a narrow interval and a portion where the rod-like members 423 are arranged at a wide interval. In the example shown in the figure, the three rod-like members 423 are arranged at a narrow interval, and the interval between the groups of every three rod-like members 423 is wide. With this configuration, the game balls that roll on the first arrangement portion 423a bounce strongly against the rod-like member 423 at a wide interval, so that the way the game balls roll is irregular, and the visual interest is enhanced. Can be increased.
In the first arrangement portion 423a of the present embodiment, the diameter of the game ball is narrower even at a wide interval. Accordingly, the game ball does not pass between the rod-like members 423 and jump out of the guidance unit 420. On the other hand, it is also conceivable that the wide gap portion is wider than the diameter of the game ball and passes between the rod-like members 423.

  As shown in FIGS. 12 and 14, a plurality (four in the illustrated example) of rod-like members 423 are arranged in the second array portion 423b with a wide space therebetween. The interval between the rod-like members 423 in the second array portion 423b is slightly wider than the diameter of the game balls. Similarly, the distance between the rod-shaped members 423 at both ends of the second array portion 423b and the rod-shaped members 423 at the ends of the first array portion 423a and the third array portion 423c is also slightly wider than the diameter of the game balls. Therefore, the game ball hits the rod-like member 423 and jumps in a complicated manner, but may pass between the rod-like members 423 and come out of the guidance unit 420. The game balls that have passed through the space between the two specific rod-like members 423 in the second array portion 423b and have gone out of the guide unit 420 win the first starting port 121. Referring to FIG. 9-4, in the guiding unit 420, a through hole 121a that constitutes the first start port 121 is located immediately below a bar-like member 423 (see FIG. 12) corresponding to the two central parts of the second array portion 423b. doing. Therefore, when the game ball passes between the two rod-like members 423 at the center in the second arrangement portion 423b, the game ball passes through the notch 424a provided in the edge portion 424 of the base portion 421 and wins the first start port 121. To do.

  Also, as shown in FIGS. 12 and 14, the rod-like members 423 are arranged at equal intervals throughout the third arrangement portion 423c. Therefore, the game balls rolling on the third array portion 423c are guided toward the second array portion 423b without jumping on the way. However, in an actual game, the game balls guided to the first array unit 423a are guided to return to the second array unit 423b after passing through the second array unit 423b to the third array unit 423c. In the process, the game balls bounce at the wide interval portion of the first array portion 423a and the second array portion 423b, so that the manner of rolling the game balls is not uniform and complicated also in the third array portion 423c. And the visual interest of the player who visually recognizes the game ball guided to the guidance unit 420 is further enhanced.

FIG. 15 is a diagram illustrating the movement of the game ball passing through the inside of the guidance unit 420.
As shown in FIG. 15, the game ball that has entered the inside of the guidance unit 420 from the left end of the guidance unit 420 is guided to the guidance surface 427 of the protrusion 426. Then, the game ball is guided to the convex piece 428 of the wall portion 425 at the end portion of the guide surface 427, and falls onto the rod-like member 423 of the first array portion 423a due to the step. The game ball that has dropped onto the rod-shaped member 423 is guided to the center of the guiding unit 420 while bouncing on the rod-shaped member 423 with the momentum that has been dropped. Further, as described above, the first arrangement portion 423a has a place where the interval between the rod-like members 423 is narrow and a place where the distance is wide, so that the manner of rolling the game ball becomes more complicated and irregular. And the visual interest of the player who visually recognizes the game ball guided to the guidance unit 420 is further enhanced.

FIG. 16 is a diagram schematically illustrating a state in which the vicinity of the protruding portion 426 in the guidance unit 420 is viewed from above.
In the example illustrated in FIG. 16, the protrusions 429 are alternately provided on the opposing surfaces of the base portion 421 and the cover member 422 (the inner surface of the guide unit 420). With such a configuration, the game ball that has entered the inside of the guidance unit 420 hits the protrusion 429 and travels while being swung left and right when passing over the guidance surface 427 of the protrusion 426. As a result, the way the game balls roll becomes more complicated and irregular. And the visual interest of the player who visually recognizes the game ball guided to the guidance unit 420 is further enhanced.

  The game ball guided to the center of the guide unit 420 jumps with the rod-like member 423 of the second array portion 423b or moves to the third array portion 423c with the momentum rolling on the first array portion 423a, and then the second array portion 423b. And return to the outside of the guiding unit 420 through the space between the rod-like members 423 of the second array portion 423b. At this time, as described above, the game ball that has passed between the two rod-like members 423 located at the center of the second arrangement portion 423b is almost awarded to the first start port 121. In addition, the game balls that have passed between the other rod-shaped members 423 flow down the game area 111 almost without winning the first starting port 121, but the game balls move when passing between the rod-shaped members 423. Depending on the direction and the moving speed, the first start port 121 may be awarded. On the other hand, even a game ball that passes between two rod-like members 423 located at the center of the second array portion 423b may not win the first start port 121.

  Here, by adjusting the overall shape of the guiding unit 420, in particular, the interval between the rod-shaped members 423, the length, shape, and inclination angle of the rod-shaped members 423, the game ball that has come out of the guiding unit 420 is first started. An approximate probability of winning the mouth 121 can be set. In the guiding unit 420 shown in FIGS. 11A to 14, the distance between the two rod-like members 423 located at the center of the second array portion 423 b has the greatest influence on the winning probability to the first start port 121. It is. That is, if the interval between the two rod-shaped members 423 is wide and the game ball easily passes, the winning probability to the first start port 121 is increased, and if the interval is small and the game ball is difficult to pass, the first start port 121 is increased. The probability of winning a prize is reduced. In the guide unit 420 of the present embodiment, the cover member 422 connects the rod-like members 423 as the connecting members, and therefore the arrangement positions of the rod-like members 423 and the intervals between the rod-like members 423 are fixed. Therefore, in order to change the winning probability for the first start port 121, the interval between the rod-like members 423 cannot be increased or decreased.

[Installation of induction unit]
FIG. 17 is a diagram schematically showing how the guidance unit 420 is mounted on the game board main body 400.
As shown in FIG. 17, the guidance unit 420 is attached to the game board main body 400 from the back side of the game area 111 where the game balls flow down. Specifically, the front side of the edge portion 424 of the base portion 421 (the side on which the bar-like member 423 is embedded and the cover member 422 is attached) is positioned with the back side surface of the game board main body 400 positioned, and the edge portion 424 is placed on the game board The guidance unit 420 is fixed to the game board main body 400 by screwing to the main body 400. By adopting such a configuration, the guidance unit 420 cannot be removed unless it is operated from the back side of the game board 110 with various devices provided inside the pachinko gaming machine 100 removed. This can contribute to the prevention of fraudulent acts such as exchanging 420 with an unauthorized unit having a different arrangement of the rod-shaped member 423.

Further, as shown in FIG. 19, the rod-like member 443 includes a first array portion 443a arranged on the left side of the guide unit 440, like the rod-like member 423 of the guide unit 420 described with reference to FIGS. The second arrangement portion 443b arranged at a wide interval in the center of the guidance unit 440 and the third arrangement portion 443c arranged on the right side of the guidance unit 440 (left side as viewed from the back side).

  The guidance unit 440 shown in FIGS. 18 to 21 has the same configuration as the guidance unit 420 described with reference to FIGS. 11A to 14 except that the base 441 is configured as a part of the center decoration 410. Has been. That is, the cover member 442 can be grasped as a connecting member that connects and fixes the end portions of the rod-shaped member 443, and the cover member 442 and the base portion 441 fix both ends of the rod-shaped member 443, It can also be grasped as a covering member that covers the passage of the game ball formed by the above. Further, the cover member 442 is formed of a light-transmitting member. Thereby, the player can visually recognize how the game ball is guided inside the guidance unit 440.

  The base portion 441 of the guidance unit 440 has a wall portion 445 that rises from the base portion 441 on the upper edge portion when attached to the game board main body 400. With the wall portion 445, the upper surface of the guiding unit 440 is closed in a state where the base portion 441 and the cover member 442 are combined. The base portion 441 has a protruding portion 446 that rises from the base portion 441 at the left end. The upper surface of the protruding portion 446 serves as a guide surface 447 for guiding a game ball that has entered from the end of the guide unit 440. Further, the protruding portion 446 and the rod-shaped member 443 are provided such that the guide surface 447 and the rod-shaped member 443 have a step. Furthermore, the wall portion 445 of the base portion 441 has a convex piece 448 that rises downward at a position facing the end portion of the guide surface 447 of the protruding portion 446.

  As described above, the rod-like member 443 of the guide unit 440 is divided into the first array portion 443a, the second array portion 443b, and the third array portion 443c, which have been described with reference to FIGS. The rod-like members 443 are arranged in the same manner as the first arrangement portion 423a, the second arrangement portion 423b, and the third arrangement portion 423c of the rod-like member 423 of the guide unit 420.

  Accordingly, the guidance unit 440 shown in FIGS. 18 to 21 functions in the same manner as the guidance unit 420 described with reference to FIGS. 11A to 14, and guides the game ball that has entered the guidance unit 440 to obtain a predetermined value. The first starting port 121 is made to win a game ball with a probability based on the setting. Also in this guiding unit 440, since the cover member 442 connects the rod-like members 443 as the connecting members, the arrangement positions of the rod-like members 443 and the intervals between the rod-like members 443 are fixed. Therefore, in order to change the winning probability for the first start port 121, the interval between the rod-like members 443 cannot be increased or decreased.

  Moreover, since the guidance unit 440 shown in FIGS. 18 to 21 constitutes a part of the center decoration 410, only the guidance unit 440 cannot be removed and replaced. Therefore, it is possible to contribute to the prevention of fraudulent acts such as replacing the guidance unit 420 with an unauthorized unit having a different arrangement of the rod-like members 423.

  When the rod-like members 423 and 443 of the guidance units 420 and 440 according to the present embodiment are regarded as a kind of game nail, the game area 111 of the pachinko gaming machine 100 according to the present embodiment is changed to a game ball. It can also be understood that the rod-shaped members 423 and 443 as game nails that cannot adjust the flow path of the game and the game nails 430 that can adjust the flow path of the game ball by changing the interval are provided. . Then, for example, for the first starting port 121 where the winning becomes a special symbol lottery and greatly affects the progress of the game, the game balls are guided by the guide units 420 and 440, and the game nail 430 is used for the other parts. The gaming area 111 may be configured to provide

  As described above, in the present embodiment, the rod-shaped members 423 and 443 are arranged to form a passage for guiding the game ball, and both ends of the rod-shaped members 423 and 443 are connected to the base portions 421 and 441 and the cover members 422 and 442, respectively. In this way, the game balls are guided using the guidance units 420 and 440 configured such that the interval between the rod-like members 423 and 443 cannot be changed, and the winning to the first start port 121 is controlled. The guiding units 420 and 440 according to the present embodiment are configured to cover the path of the game ball with the base portions 421 and 441 and the cover members 422 and 442, but the guiding unit in the present invention is limited to the above configuration. It is not a thing. For example, instead of the cover members 422 and 442 described above, the rod-shaped member 423 is formed by a connecting member that is formed in a plate shape or a rod shape and that simply connects ends that are not embedded in the base portions 421 and 441 of the rod-shaped members 423 and 443. It is good also as a structure which fixes the edge part of 443. FIG.

  Further, the guidance unit 420 (see FIGS. 9-4 to 17) and the guidance unit 440 (see FIGS. 18 to 21) according to the present embodiment are all game board main bodies 400 among members constituting the game board 110. Although one end of the rod-like members 423 and 443 is embedded in the base portions 421 and 441 attached to the guide unit 421, the guide unit in the present invention is not limited to the above-described configuration. For example, one end of a rod-shaped member may be directly embedded in the game board main body 400, and the other end of the rod-shaped member may be connected and fixed by a cover member. As an example of a specific configuration, a support member that supports a game nail is provided in a receiving portion that receives a game ball of a winning opening (first starting port 121, second starting port 122, normal winning port 126, etc.), and this supporting member It is conceivable that the gaming nail interval cannot be changed by supporting the gaming nail.

[Regarding the regular prize opening unit 460]
Next, a description will be given of a case where the above-described both-end-fixed rod-like members 423 and 443 are applied to the normal winning slot unit 460 of the game board 110. The normal prize opening unit 460 is configured by integrally forming three normal prize openings 126 arranged in a row, and is also referred to as a triple prize opening. Although winning balls are paid out to the normal winning opening 126, a lottery is not performed.

FIG. 22 is an exploded perspective view showing the attachment of the normal prize opening unit 460 to the game board 110.
As shown in FIG. 22, the normal winning slot unit 460 is attached to the positions of three openings 408 formed in the game board main body 400 of the game board 110. More specifically, the normal winning slot unit 460 is attached from the front surface 400a of the game board main body 400, and is connected to the discharge unit 470 disposed on the rear surface 400b (see FIG. 9-2). The discharge unit 470 includes a part or all of a discharge passage through which a game ball that has entered a ball in any of the three normal winning ports 126 in the normal winning port unit 460 passes.

More specifically, a ball abutting portion 480 is attached to the game board main body 400 so that a game ball flowing down the left area in the game area 111 is directed toward the normal winning opening 126. When the ball pad 480 is attached to the game board main body 400, the ball pad 480 is positioned adjacent to the rail member 112 (see also FIG. 1). Note that the ball abutment portion 480 is located obliquely above and to the left of the normal prize opening unit 460, and is located upstream of the normal prize opening unit 460 in the flow direction of the game ball.
The ball abutting portion 480 is connected to and attached to the discharge unit 470 located on the rear surface 400b of the game board main body 400. Thereby, the firm attachment to the game board main body 400 of the ball | bowl contact part 480 is implement | achieved.

FIG. 23 is a diagram for explaining the configuration of the normal winning a prize opening unit 460, (a) is an exploded perspective view, and (b) is a vertical partial sectional view.
As shown in FIG. 23 (a), the normal prize opening unit 460 is provided in each of the base plate 461 having openings 461 a corresponding to the three openings 408 of the game board main body 400 and the openings 461 a of the base plate 461. And a front decoration member 462 disposed correspondingly.
The normal winning opening unit 460 includes two rod-like members 463 that are connected to the normal winning opening 126 so as to connect the base plate 461 and the front decoration member 462 facing each other. The interval between the two rod-like members 463 is a dimension through which a game ball passes. One end of the rod-shaped member 463 is not a free end, and both ends are embedded and fixed. That is, the base plate 461, the front decoration member 462, and the rod-shaped member 463 in the normal winning opening 126 are integrated.

  One end of the rod-like member 463 is embedded in the base plate 461, and the other end is embedded in the front decoration member 462. More specifically, as shown in FIG. 23 (b), a raised portion 461 b for securing the amount of embedding of the rod-like member 463 is formed on the front surface of the base plate 461. A similar raised portion is also formed on the rear surface of the front decoration member 462.

  In this way, each of the normal winning holes 126 has a space formed by the base plate 461 and the front decoration member 462, and such a space becomes a passage through which a game ball won in the normal winning hole 126 passes. It is configured. In addition, two bar-like members 463 that are fixed so as to maintain a predetermined interval are disposed at the entrance of the normal winning opening 126. For this reason, the positional relationship between the bar-shaped member 463 and the base plate 461 and the front decoration member 462 is fixed, and the secular change of the bar-shaped member 463 at the hall store can be prevented.

  In addition, the structure provided with the rod-shaped member which the normal winning opening unit 460 is located in the path | route led to the normal winning opening 126, and has a function as a closing nail is also considered. That is, not only the above-described bar-shaped member 463 but also a bar-shaped bar-shaped member is embedded in the base plate 461 and the front decoration member 462. An example in which at least three rod-like members are arranged as such a nail can be considered.

Here, in the guidance units 420 and 440 described above, the interval between the rod-like members 423 and 443 located at the entrance of the first start port 121 is fixed. And the entrance rate to the 1st starting port 121 influences by the space | interval of such rod-shaped members 423 and 443. FIG. Therefore, guide units 420 and 440 with a wide space between the rod-like members 423 and 443 and narrow guide units 420 and 440 are set in advance to provide a service that can be selected according to the hall store circumstances such as a rental rate. The form to do is conceivable. In the case of adopting such a form, it is conceivable to display the guidance units 420 and 440 so that the interval between the rod-like members 423 and 443 can be specified, that is, a display indicating the performance.
Such a form can be considered not only for the guidance units 420 and 440 but also for the above-described normal prize opening unit 460.

In this way, in the guidance units 420 and 440 and the normal winning a prize opening unit 460, the rod-like members 423, 443, and 463 are fixed at both ends, and adjustment is not required at the hall store after factory shipment. In other words, the guiding units 420 and 440 and the normal winning a prize opening unit 460 are configured to make it difficult to adjust the behavior of the game ball in the hall store.
From this point of view, in the game board 110 using a general game nail instead of the rod-shaped members 423, 443, and 463, a transparent board material (not shown) that covers the entire board surface of the game board 110 is held by the transparent board holding frame 91. It is possible to adopt a modification example that is interposed between the transparent plate 159 (see FIG. 9-1 (b)) and the game board 110. That is, even if the transparent board holding frame 91 is opened, it is difficult to access the board surface of the game board 110 by a transparent board material (not shown) that covers the entire board surface. Of course, even if the game board holding frame 92 is opened (see FIG. 9-1 (a)), it is difficult to access the board surface of the game board 110.
In addition to the configuration example that prevents access to the board surface of the game board 110 after factory shipment, it is possible to remove a transparent plate (not shown) that covers the entire board surface by using a special tool instead of a general tool. Various configuration examples are also conceivable.

  Although the present invention has been described using the embodiment, the technical scope of the present invention is not limited to the above embodiment. It will be apparent to those skilled in the art that various modifications and alternative embodiments can be made without departing from the spirit and scope of the invention.
