A number of these decorative lamps 16 are provided around the gaming machine 1, for example, on the periphery of the front frame 4 and within the side unit 7.

In addition, speakers 17 that produce sound effects (sound effects) through acoustics are provided on both sides of the upper part of the inner frame 3 and on the upper side of the launch operation handle 15.
The multiple speakers 17 enable so-called stereophonic reproduction or multi-channel sound reproduction for sounds related to the performance.

Next, the configuration of the game board 5 will be described with reference to Fig. 3. Fig. 3 is a front view of the game board 5.
The illustrated game board 5 has a ball guide rail 18 that guides the launched game ball attached in a ring shape as a board surface partition member, and the approximately circular area surrounded by this ball guide rail 18 is the game area 19, while the four corners are non-game areas.
The game area 19 is a space formed between the game board 5 and the transparent glass 6, and is an area through which game balls can flow down.

A liquid crystal display device (LCD) 20 is provided in the approximate center of this game area 19. The liquid crystal display device 20 is capable of performing variable display operations (variable display and stationary display) of multiple types of decorative patterns (for example, a left pattern (corresponding to the left display area), a middle pattern (corresponding to the middle display area), and a right pattern (corresponding to the right display area)) using numbers, characters, symbols, etc., independently in, for example, three (left, middle, right) display areas (variable pattern display areas).
Under the control of a performance control board 41 described later, the liquid crystal display device 20 displays various performances as images, in addition to the varying display operation of decorative symbols.

In addition, a center ornament 21 is provided in the center of the game area 19 so as to surround at a distance the display surface of the liquid crystal display device 20. The center ornament 21 is provided along the front side of the game board 5, and protects the display surface of the liquid crystal display device 20 from collision with game balls, and also functions as a flow path distribution means that enables the flow path of the game ball to be distributed to the left or right depending on the strength or stroke length of the game ball's launch.
In this embodiment, the center ornament 21 is disposed at approximately the center of the play area 19, and divides the play area 19 into a left play area 19a and a right play area 19b on the left and right sides. A game ball launched by the launching device 44 with a launch strength less than a predetermined value flows down the left play area 19a, and a game ball launched with a launch strength equal to or greater than the predetermined value flows down the right play area 19b.

The non-play area at the bottom of the game board 5 is a display section for various functions, and is provided with a special symbol display device 22a and a special symbol display device 22b using dot displays.
In addition, various function display sections including the special symbol display devices 22a and 22b are shown in an enlarged scale in FIG.

The special symbol display devices 22a and 22b are adapted to execute a special symbol variable display game by varying the display operation of the "special symbol" represented by the dot display. The liquid crystal display device 20 described above is adapted to execute a decorative symbol variable display game together with various preview effects (effect images) by displaying decorative symbols in a variable display manner that is synchronized in time with the variable display of the special symbols by the special symbol display devices 22a and 22b.

The various function display section also includes a composite display device 22c, which is made up of a dot display device, just like the special symbol display devices 22a and 22b. It is called a composite display device because it is a reserved/time-saving/high-probability composite display device (hereinafter simply referred to as a "composite display device") that has five display functions: displaying the first special symbol (hereinafter, the first special symbol will be referred to as "special symbol 1" and sometimes abbreviated to "special symbol 1"), the second special symbol (hereinafter, the second special symbol will be referred to as "special symbol 2" and sometimes abbreviated to "special symbol 2"), the number of reserved balls for normal symbols, and notifying the status during the time-saving state and the high-probability state.

The various function display section is also provided with a composite display device 22d, which is also made up of a dot display.
In this composite display device 22d, a round number display is performed to notify the specified number of rounds (maximum number of rounds) related to a jackpot by combining the on/off states of four LEDs.
In addition, in the composite display device 22d, as the normal symbol display, a normal symbol variable display game is executed by a variable display operation of the normal symbol represented by one LED.
In addition, the composite display device 22d is configured to display a right-hand hit display using three LEDs. The right-hand hit display indicates that it is more advantageous for the player to shoot the game ball toward the right game area 19b than to shoot the game ball toward the left game area 19a.

A first starting hole 23 is provided in the center of the game board 5 and below the liquid crystal display device 20. Inside the first starting hole 23, a first starting hole detection sensor 23a (see FIG. 4) is provided to detect the passage of a game ball.
A second starting hole 24 is provided in the right game area 19b, and a second starting hole detection sensor 24a (see Figure 3) is provided inside the second starting hole 24 to detect the passage of a game ball.

The first starting hole 23 is a winning hole related to the starting condition of the variable display operation of the special symbol 1 in the special symbol display device 22a, and is configured as a fixed starting hole without a starting hole opening/closing means (means for opening or enlarging the starting hole). In this embodiment, due to the action of a game ball fall direction changing member (e.g., a game nail, a windmill, a center ornament 21, etc.) in the game area 19, the first starting hole 23 is configured to be easy for game balls rolling in the left game area 19a to enter, but difficult or impossible for game balls rolling in the right game area 19b to enter.

The second starting port 24 is a winning port related to the starting conditions for the variable display operation of the special pattern 2 in the special pattern display device 22b, and is configured as a variable starting port whose opening and closing is controlled by a normal electric device 25.
The normal electric device 25 is controlled to an open state that allows a game ball to enter the second starting hole 24, and a closed state that makes it difficult or impossible for a game ball to enter the second starting hole 24. In this embodiment, the second starting hole 24 is provided in the right playing area 19b, and only game balls that have rolled in the right playing area 19b can enter the hole, but game balls that have rolled in the left playing area 19a may also be allowed to enter the hole.

Above the second starting hole 24, that is, above the middle part of the right play area 19b, there is provided a normal symbol gate 26 through which game balls can pass. This normal symbol gate 26 is a winning hole related to the variable display operation of the normal symbol in the composite display device 22d, and inside it is provided a normal symbol gate detection sensor 26a (see FIG. 4) that detects game balls passing through. In this embodiment, the normal symbol gate 26 is provided only in the right play area 19b, and only game balls that have rolled in the right play area 19b can enter. However, the present invention is not limited to this, and it may be provided only in the left play area 19a, or in both.

A first large prize opening 27 and a second large prize opening 28 are provided below the second starting opening 24 in the right game area 19b. The first large prize opening 27 and the second large prize opening 28 are arranged in a position where only game balls rolling in the right game area 19b can enter. However, the first large prize opening 27 and the second large prize opening 28 may be arranged so that only game balls rolling in the left game area 19a can enter, or so that game balls rolling in the left game area 19a and the right game area 19b can enter.
The first large prize opening 27 is controlled to open and close by a first special electric device 29. The first special electric device 29 is controlled to an open state that allows a game ball to enter the first large prize opening 27, and a closed state that makes it difficult or impossible for a game ball to enter the first large prize opening 27.
The second large prize opening 28 is controlled to open and close by a second special electric device 30. The second special electric device 30 is controlled to an open state that allows a game ball to enter the second large prize opening 28, and a closed state that makes it difficult or impossible for a game ball to enter the second large prize opening 28.
A first large prize opening detection sensor 27a and a second large prize opening detection sensor 28a (see Figure 4) are provided inside the first large prize opening 27 and the second large prize opening 28, respectively, to detect the passage of a gaming ball.

In addition, a plurality of general winning openings 31 are provided on the lower left and right sides of the game area 19, and a general winning opening detection sensor 31a (see Figure 4) is provided inside each of them to detect the passage of game balls.
Additionally, within the area of the game board, movable devices (not shown) that provide visual effects are arranged in positions that do not interfere with the rolling of the game ball.

In the gaming machine 1 of this embodiment, when a gaming ball enters one of the various winning holes provided in the gaming area 19, the number of prize balls set for the winning hole into which the gaming ball entered (for example, three for the first start hole 23, one for the second start hole 24, fifteen for the first large winning hole 27 and the second large winning hole 28, and five for the general winning hole 31) is paid out from the gaming ball payout device 46 (see FIG. 4). Gaming balls that do not enter any of the above winning holes are discharged from the gaming area 19 via the outlet hole 32.

2. Control configuration of gaming machine
Fig. 4 is a block diagram showing a control configuration of the gaming machine 1. A configuration (control configuration) for realizing game operation control of the gaming machine 1 will be described with reference to the block diagram of Fig. 4.
The gaming machine 1 of this embodiment is composed of a main control board 40 that is responsible for overall control of all gaming operations (gaming operation control), a presentation control board 41 that receives presentation control commands from the main control board 40 and is responsible for overall control of the execution of presentations by the presentation means, a payout control board 42 that controls the payout of prize balls, and a power supply board (not shown) that generates and supplies the power supply voltage required for the gaming machine 1 from an external power source.

2.1 Main control board
The main control board 40 is equipped with a microprocessor that incorporates a CPU (Central Processing Unit) 40a (main control CPU), as well as a ROM (Read Only Memory) 40b (main control ROM) that stores a control program describing game operation control procedures as well as various data necessary for game operation control, and a RAM (Random Access Memory) 40c (main control RAM) that functions as a work area and buffer memory, and as a whole constitutes a microcomputer.

Although not shown, the main control board 40 also includes a CTC (Counter Timer Circuit) for implementing periodic interrupts, a constant-period pulse output creation function (bit rate generator), and time measurement functions, an interrupt controller circuit that performs interrupt enable/disable functions such as timer interrupts that provide interrupt signals to the CPU 40a, a reset circuit that detects power-on/off and power supply abnormalities and outputs a system reset signal to reset the CPU 40a, a watchdog timer (WDT) circuit that monitors for operational abnormalities in the control program, an IAT (Inhibit Outside Designated Area) circuit that monitors whether a program is being executed correctly within a preset address range, and a counter circuit for generating random numbers within a certain range in hardware.

The counter circuit is comprised of a random number generation circuit that generates random numbers, and a sampling circuit that samples random numbers from the random number generation circuit at a predetermined timing, and functions as a 16-bit counter as a whole. The CPU 40a sends instructions to the sampling circuit according to the processing state, thereby obtaining the number indicated by the random number generation circuit as a random number for determining a jackpot (0 to 65535), and uses the random number for determining a jackpot (win/lose lottery). Note that the random number for determining a jackpot is obtained by adding a soft random number generated by appropriate software processing and a hard random number to prevent cheating such as aiming for a win.

The main control board 40 is connected to a first start gate detection sensor 23a that detects the entry of a game ball into the first start gate 23, a second start gate detection sensor 24a that detects the entry of a game ball into the second start gate 24, a normal pattern gate detection sensor 26a that detects the passage of a game ball into the normal pattern gate 26, a first large prize gate detection sensor 27a that detects the entry of a game ball into the first large prize gate 27, a second large prize gate detection sensor 28a that detects the entry of a game ball into the second large prize gate 28, a general prize gate detection sensor 31a that detects the entry of a game ball into the general prize gate 31, and an OUT monitoring sensor 32a that detects game balls (out balls) discharged from the game area 19. The main control board 40 is capable of receiving detection signals output from these. Therefore, the main control board 40 can determine which winning hole the game ball has entered based on the detection signals from each sensor.

Also connected to the main control board 40 are a normal electric role solenoid 25a that operates the normal electric role 25 that opens and closes the second starting opening 24, a first special electric role solenoid 29a that operates the first special electric role 29 that opens and closes the first large winning opening 27, and a second special electric role solenoid 30a that operates the second special electric role 30 that opens and closes the second large winning opening 28. The main control board 40 is capable of transmitting control signals to control these.

In addition, the special symbol display device 22a and the special symbol display device 22b are connected to the main control board 40. The main control board 40 is capable of transmitting a control signal for controlling the display of the special symbols 1 and 2.
In addition, the composite display device 22c and the composite display device 22d are connected to the main control board 40. The main control board 40 is capable of transmitting control signals for controlling the display of various information displayed on the composite display device 22c and the composite display device 22d.

The main control board 40 is connected to the RAM clear switch 33 and is capable of receiving a detection signal from the RAM clear switch 33 .
The RAM clear switch 33 is operable when the front frame 4 is open, and is disposed, for example, on the main control board 40. The RAM clear switch 33 is, for example, a push button switch for inputting an instruction to initialize a predetermined area of the RAM 40c.

Furthermore, the performance indicator 34 is connected to the main control board 40 .
The performance indicator 34 is configured to have, for example, a seven-segment display, and functions as a display means capable of displaying performance information described later. The performance indicator 34 is mounted, for example, on the main control board 40 or the dispensing control board 42 at a position where it can be easily seen.
The main control board 40 is capable of transmitting a control signal to the performance display 34 for displaying performance information.

The payout control board 42 is connected to the main control board 40, and when it is necessary to pay out prize balls, a control command related to the payout (a payout control command that specifies the number of prize balls) can be sent to the payout control board 42.

In addition, an external centralized terminal board for frames 43 is connected to the main control board 40 via a payout control board 42, making it possible to transmit specified game information (e.g., jackpot information, number of winning balls information, pattern change execution information, etc.) to an externally installed hall computer HC.
The hall computer HC is an information processing device (computer device) that monitors game information from the main control board 40 and comprehensively manages the operating status of the gaming machines in the pachinko hall.

The payout control board 42 is connected to a launch control board 45 that controls the launch device 44, and a game ball payout device 46 that pays out game balls. The main role of this payout control board 42 is to receive payout control commands from the main control board 40, control the payout of prize balls by the game ball payout device 46 based on the payout control commands, and send status signals to the main control board 40.

The game ball payout device 46 is provided with a supply shortage detection sensor 46a that detects a shortage of game balls and a ball counting sensor 46b that detects the game balls (prize balls) to be paid out, and the payout control board 42 is capable of receiving each of these detection signals. The game ball payout device 46 is also provided with a payout motor 46c that drives a ball payout mechanism (not shown) for paying out game balls, and the payout control board 42 is capable of transmitting a control signal for controlling the payout motor 46c.

The payout control board 42 is connected to a full-ball detection sensor 47 that detects when the upper tray 10 is full of game balls, and a front door open sensor 48 that detects when the front frame 2 is open.

The payout control board 42 is capable of transmitting various status signals to the main control board 40 based on detection signals from the full detection sensor 47, the front door open sensor 48, the supply shortage detection sensor 46a, and the ball counting sensor 46b. These status signals include a ball jamming signal indicating a full state, a door open signal indicating that at least the front frame 2 is open, a supply shortage signal indicating a shortage of game balls from the game ball payout device 46, a counting error signal indicating a shortage of prize balls paid out or an abnormality has occurred in the ball counting sensor 46b, and a payout completion signal indicating that the payout operation has been completed, and is configured to be capable of transmitting various status signals. Based on these status signals, the main control board 40 monitors the open state of the front frame 2 (door open error), whether the payout operation of the game ball payout device 46 is normal or not (supply shortage error), and the full state of the upper tray 10 (ball jamming error).

The payout control board 42 is also capable of transmitting a permission signal to the launch control board 45 to permit launch. Based on the permission signal being output from the payout control board 42, the launch control board 45 controls the energization of the launch solenoid (not shown) provided in the launch device 44, and realizes the launch operation of the game ball by operating the launch operation handle 15. Specifically, the launch operation of the game ball is permitted under the conditions that the launch permission signal is output from the payout control board 42 (launch permission signal ON state), the touch sensor (not shown) provided in the launch operation handle 15 detects that the player is touching the handle, and the launch stop switch (not shown) provided in the launch operation handle 15 is not operated. Therefore, when the launch permission signal is not output (launch permission signal OFF state), the launch operation is not executed even if the launch operation handle 15 is operated, and the game ball is not launched. In addition, the launch strength of the game ball can be changed according to the amount of operation of the launch operation handle 15.
In addition, the payout control board 42 outputs a launch permission signal to the launch control board 45 on the condition that launch permission is instructed by the main control board 40.

(About performance indication)
The main control board 40 is capable of transmitting a control signal to the performance display 34 for displaying predetermined performance information.
Performance information is information that pachinko halls and related agencies want to confirm, and typical examples include information regarding the presence or absence of illegal prize ball cheating, such as excessive prize balls for the gaming machine 1, and information regarding the original ball output performance of the gaming machine 1. Therefore, unlike preview performances, the performance information itself is information that is not directly related to the progress of the game itself when a player is playing the game.

For this reason, the performance display 34 is provided inside the gaming machine 1, for example, on the main control board 40, payout control board 42, launch control board 45, relay board, presentation control board 41, or in the board case (protective cover that protects the board), in a position where the display information can be seen when the front frame 2 is in the open state.

Here, the performance information may specifically include the following information:
(1) Information (specific ratio information) based on the value (α/β) obtained by dividing the total number of payout balls paid out as a result of winning during a specific state (total number of prize balls during a specific state: α) by the total number of out balls discharged from the game area 19 during the specific state (number of out balls during a specific state: β) can be adopted as performance information.
The above "total number of payouts" refers to the total value of game balls (prize balls) paid out when game balls enter (win) the winning holes (first start hole 23, second start hole 24, general winning hole 31, first large winning hole 27, second large winning hole 28).
In addition, the state to be adopted as the specific state can be appropriately determined according to the state under which the performance information is to be grasped. In the case of this embodiment, any state among a plurality of game states and a jackpot game can be adopted. In addition, a plurality of types of states may be the measurement target. For example, all game states except a jackpot game, and the type to be measured can be appropriately determined.
In addition, the total number of payouts may be calculated by excluding one or more specific winning ports from the measurement (total number of payouts excluding specific winning ports). For example, the total number of payouts may be calculated by excluding the first large winning port 27 and the second large winning port 28 from the measurement.

(2) Alternatively, the total number of balls paid out, the total number of balls paid out excluding a specific winning slot, or the total number of balls taken out may be measured, and the measurement results may be used as performance information.

In this embodiment, the total number of payouts during normal state (number of payouts under normal conditions) and the total number of balls out during normal state (number of balls out under normal conditions) are measured in real time, and the value obtained by dividing the number of payouts under normal conditions by the number of balls out under normal conditions and multiplying this value by 100 (the value calculated by number of payouts under normal conditions ÷ number of balls out under normal conditions × 100) is displayed as performance information (hereinafter referred to as "normal ratio information"). Note that the displayed value in this case is rounded off to one decimal place.
Therefore, each data of the number of payouts in normal time, the number of out balls in normal time, and the ratio information in normal time is stored (memorized) in the corresponding area of the RAM 40c (the storage area for the total number of prize balls in specific time, the storage area for the number of out balls in specific time, and the storage area for the specific ratio information). However, instead of simply measuring permanently and displaying the performance information, when the total number of out balls reaches a predetermined specified number (for example, 60,000 balls), the measurement is temporarily terminated. This specified number is not the total number of out balls in the normal state, but the total number of out balls in all game states (including during a winning game) (hereinafter referred to as the "number of out balls in all states"). This number of out balls in all states is also measured in real time and stored in the corresponding area of the RAM 40c (the storage area for the number of out balls in all states). Hereinafter, for the convenience of explanation, the storage area for the total number of prize balls in specific time, the storage area for the number of out balls in specific time, the storage area for the specific ratio information, and the storage area for the number of out balls in all states are abbreviated to "measurement information storage area".

The normal time ratio information at the end is then stored in a specified area (performance display storage area) of RAM 40c (this normal time ratio information is stored), and then the measurement information storage area (number of payouts at normal time, number of out balls at normal time, and number of out balls in all states) is cleared, and measurement is started again (measurement of number of payouts at normal time, number of out balls at normal time, normal time ratio information, and number of out balls in all states is started). The performance display 34 then displays the previous normal time ratio information (measurement history information) and the normal time ratio information currently being measured. Note that it is not limited to the previous information, and it may be configured to display history from the time before that or the time before that (three times ago), and it is possible to determine how many times back the information to display.

(Performance control command)
The main control board 40 is capable of transmitting various presentation control commands, including information on the special symbol variation display game and information on errors, to the presentation control board 41 according to the processing state. However, in order to prevent fraudulent acts such as cheating, the main control board 40 is configured for one-way communication in which it only transmits signals to the presentation control board 41 and cannot receive signals from the presentation control board 41.

Here, the performance control command defines the function by a two-byte configuration consisting of a one-byte-long mode (MODE) and a one-byte-long event (EVENT), and in order to distinguish between MODE and EVENT, Bit 7 of MODE is ON and Bit 7 of EVENT is OFF. When these pieces of information are transmitted as valid, a strobe signal is output corresponding to each of the mode (MODE) and event (EVENT). That is, when there is a command to be transmitted, the CPU 40a (main control CPU) sets and outputs mode (MODE) information for transmitting the command to the performance control board 41, and transmits the first strobe signal after a predetermined time has elapsed since this setting. Furthermore, after a predetermined time has elapsed since the transmission of this strobe signal, it sets and outputs event (EVENT) information, and after a predetermined time has elapsed since this setting, it transmits the second strobe signal. The strobe signal is controlled to an active state by CPU 40a for a predetermined period of time to ensure that CPU 41a (performance control CPU) can receive commands.

[2.2 Performance control board]
The performance control board 41 is equipped with a microprocessor with a built-in CPU 41a, and is composed mainly of a microcomputer equipped with a ROM 41b that stores performance data required for performance control processing, and a RAM 41c that functions as a work area and buffer memory.In addition, it is equipped with an audio control unit (sound source IC), interface circuits with each unit, a random number generation circuit that generates random numbers to be used in lotteries for performance, a CTC for various time counts, a watchdog timer (WDT) circuit, an interrupt controller circuit that gives an interrupt signal to the CPU 41a, an RTC (Real Time Clock) function unit, a reset circuit, and so on, which control the overall performance operation.

The CPU 41a performs calculations for various presentation operations and controls each presentation means based on the presentation control program and the presentation control commands received from the main control board 40. In the case of the gaming machine 1 of this embodiment, the presentation means are the liquid crystal display device 20 (main liquid crystal display device 20M, sub-liquid crystal display device 20S), the light display device 16a, the sound generating device 17a, and the movable role device (not shown).

The ROM 41b stores a control program for the performance operation by the CPU 41a and various data required for controlling the performance operation.
The RAM 41c is used as a work area used by the CPU 41a for various arithmetic processing, a table data area, a buffer area for various input/output data and processing data, and the like.

The main role of this performance control board 41 is to receive performance control commands from the main control board 40, select and decide the performance based on the performance control commands, control the display of the liquid crystal display device 20 (supply of display data), control the sound output of the sound generating device 17a, control the light emission of the light display device 16a, and control the operation of the movable body role (drive control of the movable body role motor 50).

Since this performance control board 41 also functions as a control device for the liquid crystal display device 20, the performance control board 41 also has the functions of a so-called VDP (Video Display Processor), image ROM, and VRAM (Video RAM), and the CPU 41a also functions as a liquid crystal control unit.
VDP refers to a function for controlling the overall video output process, such as image development and image drawing.
The image ROM refers to a memory in which image data that is to be subjected to image development processing by the VDP is stored.
The VRAM is an image memory area that temporarily stores image data rendered by the VDP.

With these configurations, the performance control board 41 generates various image data based on performance control commands from the main control board 40, and outputs it to the main liquid crystal display device 20M and the sub liquid crystal display device 20S. As a result, various performance images are displayed on the main liquid crystal display device 20M and the sub liquid crystal display device 20S.
3 is the main liquid crystal display device 20M. The sub liquid crystal display device 20S is not shown in FIG.

The performance control board 41 also has an audio control section for an audio generating device 17 a including multiple speakers 17 , and the audio signal output by the audio control section is amplified by an amplifier section 17 b and supplied to the speakers 17 .
In addition, the performance control board 41 is connected to a lamp driver section 16b that functions as a light display control section for the light display device 16a including the decorative lamp 16, and a motor driver section 50a (motor drive circuit) that functions as a drive control section for the movable body role motor 50 that operates the movable body (not shown). The performance control board 41 issues instructions to the lamp driver section 16b and the motor driver section 50a to control the light display operation by the light display device 16a and the operation of the movable body role motor 50.

In addition, an origin switch 51 and a position detection sensor 52 for monitoring the operation of the movable props are connected to the performance control board 41.
The origin switch 51 is composed of, for example, a photointerrupter, and detects whether the movable body role motor 50 is at the origin position. The origin position is, for example, a position where the movable body is not normally exposed on the board surface of Fig. 2. The performance control board 41 is capable of determining whether the movable body role motor 50 is at the origin position based on the detection information of this origin switch 51.
In addition, the performance control board 41 controls the operation mode while monitoring the current operating position of the movable body role (for example, the amount of movement from the origin position) based on the detection information from the position detection sensor 52. Furthermore, the performance control board 41 monitors malfunctions in the operation of the movable body role based on the detection information from the position detection sensor 52, and if a malfunction occurs, detects it as an error.

In addition, the performance control board 41 is connected to operation detection switches for the performance button 14a, cross key 14b, and decision button 14c, which are shown as the operation unit 14, and the performance control board 41 is capable of receiving operation detection signals from the performance button 14a, cross key 14b, and decision button 14c.

Furthermore, the performance control board 41 is provided with a handle sensor 53 (touch sensor) for detecting whether the firing operation handle 15 shown in FIG. 1 is being touched by a player. The performance control board 41 is capable of determining whether the firing operation handle 15 is being touched by a user based on the detection information of the handle sensor 53.

Based on the performance control commands sent from the main control board 40, the performance control board 41 selects (determines) a performance pattern by lottery or uniquely from multiple types of performance patterns prepared in advance, and controls various performance means at the required timing to produce the desired performance. This realizes the display of a performance image by the liquid crystal display device 20 corresponding to the performance pattern, the playback of sound from the speaker 17, and the lighting and blinking of the decorative lamps 16, and the chronological development of various performance patterns (such as decorative pattern changing display operations and preview performances) to realize a "performance scenario" in the broad sense.

Here, for the performance control command, the performance control board 41 (CPU 41a) generates an interrupt process based on the input of the above-mentioned strobe signal transmitted by the main control board 40 (CPU 40a) and receives and analyzes the command. Specifically, the CPU 41a executes a control program for command reception interrupt process based on the input of the above-mentioned strobe signal, and in the interrupt process realized by this, obtains the performance control command and analyzes the command content.
In this case, when an interrupt occurs based on the input of a strobe signal, even if an interrupt process based on another interrupt (a timer interrupt process executed periodically) is being executed, the CPU 41a interrupts the process and performs command reception interrupt processing, and even if another interrupt occurs at the same time, the command reception interrupt processing is given priority.

<3. Overview of operation>
Next, an overview of the gaming operation of the gaming machine 1 realized by the above-mentioned control configuration (FIG. 4) will be described.

[3.1 Game Status]
The gaming machine 1 is configured to be able to set a plurality of types of gaming states in addition to the big win game, which is a special gaming state. To facilitate understanding of this embodiment, first, various gaming states will be described.

The gaming machine 1 progresses in a gaming state that combines either a low probability state or a high probability state with either a non-time-saving state or a time-saving state.

The low probability state is a state in which the probability of winning the jackpot lottery is relatively low, and the high probability state is a state in which the probability of winning the jackpot lottery is relatively high.
The non-time-saving state is a state in which it is relatively difficult for a game ball to enter the second start hole 24, and the time-saving state is a state in which it is relatively easy for a game ball to enter the second start hole 24. For example, the opening time of the second start hole 24 when a normal winning lottery is won is set longer in the time-saving state than in the non-time-saving state. However, if it is easier for a game ball to enter the second start hole 24 in the time-saving state than in the non-time-saving state, for example, the probability of winning the normal winning lottery may be higher or the fluctuation time of the normal pattern may be shorter in the time-saving state than in the non-time-saving state.

In this embodiment, the "normal state" refers to a low probability state and a non-time-saving state, and corresponds to the initial state.

[3.2 Variable symbol display game]
(Regarding special drawings)
In the gaming machine 1, when a game ball enters the first starting hole 23 or the second starting hole 24, that is, when a detection signal is input from the first starting hole detection sensor 23a or the second starting hole detection sensor 24a, random numbers related to the special pattern change display game described below (random numbers for determining a jackpot, random numbers for determining special patterns, random numbers for change patterns) are obtained, and these random numbers are stored as reserved data in the special pattern reserved memory area of RAM 40c up to a predetermined upper limit value, which is the maximum reserved memory number (for example, a maximum of 4).
This special symbol reserved memory area is provided with special symbol reserved memory areas corresponding to the special symbol 1 side and the special symbol 2 side, i.e., a special symbol 1 reserved memory area and a special symbol 2 reserved memory area.

These special symbol reserved memory areas are provided with reserved 1 memory area to reserved n memory area (n is the maximum reserved memory number: in this embodiment, n=4), and each of them can store the maximum reserved memory number of reserved data. The maximum reserved memory numbers of the special symbol 1 reserved memory area and the special symbol 2 reserved memory area are not particularly limited. In addition, all or part of the maximum reserved memory numbers of each symbol may be different, and the number can be appropriately determined according to the game characteristics.
The game balls related to the reserved data stored in the special symbol reserved memory area are also called "reserved balls." To make the number of reserved balls clear to the player, the dot indicators corresponding to the reserved ball numbers of special symbols 1 and 2 on the composite display 22c are lit up, or the reserved indicators provided as icon images on the screen of the liquid crystal display 20 (the main liquid crystal display 20M or the sub liquid crystal display 20S) are lit up.

(Special pattern change display game)
In the gaming machine 1, a "jackpot lottery" is performed by random number lottery in the main control board 40 based on a predetermined starting condition, specifically, based on the game ball entering (winning) the first starting hole 23 or the second starting hole 24. Based on the lottery result of the jackpot lottery, the main control board 40 displays special symbols 1 and 2 on the special symbol display devices 22a and 22b to start the special symbol variable display game, and after a predetermined variable time has elapsed, displays the result on the special symbol display devices 22a and 22b, thereby ending the special symbol variable display game. Unless otherwise necessary, "special symbol 1" and "special symbol 2" are simply referred to as "special symbols" (sometimes abbreviated to "special symbols").

Here, in this embodiment, the lottery for the jackpot of special symbol 1 based on winning the first starting hole 23 and the lottery for the jackpot of special symbol 2 based on winning the second starting hole 24 are performed separately and independently. For this reason, the lottery result for the jackpot of special symbol 1 is displayed on the special symbol display device 22a, and the lottery result for the jackpot of special symbol 2 is displayed on the special symbol display device 22b. Specifically, on the condition that a game ball has entered the first starting hole 23, the special symbol 1 is displayed in a variable manner to start the first special symbol variable display game, while on the other hand, on the condition that a game ball has entered the second starting hole 24, the special symbol 2 is displayed in a variable manner to start the second special symbol variable display game. Then, when the special pattern variable display game is started on special pattern display device 22a or special pattern display device 22b, after a predetermined variable time has elapsed, the special pattern being displayed in a variable manner is stopped and displayed in a predetermined "jackpot" manner if the jackpot lottery result is a "jackpot", or in a predetermined "miss" manner otherwise, thereby announcing the game result (jackpot lottery result).

For ease of explanation, the first special pattern change display game on the special pattern display device 22a side will be referred to as "special pattern change display game 1," and the second special pattern change display game on the special pattern display device 22b side will be referred to as "special pattern change display game 2." Furthermore, "special pattern change display game 1" and "special pattern change display game 2" will be referred to simply as "special pattern change display games."

When the result of the jackpot lottery is a "jackpot," that is, when the special pattern change display game ends and as a result a special pattern is displayed stationary in a "jackpot" mode on the special pattern display device 22a or the special pattern display device 22b, a special game state (jackpot game) which is more advantageous to the player than during the special pattern change display game occurs.

(Decorative pattern changing display game)
When the special symbol variable display game is started, the main liquid crystal display device 20M changes and displays decorative symbols (game symbols for presentation), and various presentations are performed. When the special symbol variable display game ends, the decorative symbol variable display game also ends, and the special symbol display devices 22a and 22b display predetermined special symbols indicating the result of the big win lottery, and the main liquid crystal display device 20M displays decorative symbols reflecting the result of the big win lottery. In other words, the result of the special symbol variable display game is reflected and displayed by the decorative symbol variable display game for presentation, including the decorative symbol variable display operation.

Therefore, for example, if the result of the special symbol change display game is a "jackpot" (if the jackpot lottery result is a "jackpot"), the decorative symbol change display game will develop an effect that reflects that result. Then, when the special symbol is displayed in a display mode indicating a jackpot (for example, the 7-segment display shows "7") on the special symbol display devices 22a and 22b, the decorative symbols are displayed in a display mode reflecting the "jackpot" in each of the "left", "center", and "right" display areas on the main liquid crystal display device 20M (in each of the "left", "center", and "right" display areas, the three decorative symbols are displayed in the same display state (for example, "7", "7", "7")).

Regarding the information necessary to execute the decorative pattern change display game, first, the main control board 40, based on the game ball entering the first start hole 23 or the second start hole 24, specifically, on the condition that the game ball is detected by the first start hole detection sensor 23a or the second start hole detection sensor 24a and the start condition (start condition related to the special pattern) is met, conducts a jackpot lottery to determine whether it will be a "jackpot" or a "miss", and a pattern lottery to determine the type of special pattern (jackpot type, miss type) that will finally be stopped and displayed, and determines the change pattern of the special pattern based on the result of the lottery.
In the pattern lottery, if the result of the jackpot lottery is a "jackpot", one of the multiple jackpot types will be selected by lottery, and if the result is a "miss", one of the multiple miss types will be selected by lottery. However, there may be only one jackpot type and one miss type, and in that case, the type may be determined without a lottery.
Then, the main control board 40 transmits a "variation pattern designation command" including at least information on the variation pattern of the special symbol (variation pattern information (e.g., information on the result of the big win lottery and the variation time of the special symbol, etc.)) to the performance control board 41 as a performance control command specifying the processing state. This causes basic information required for the decorative symbol variation display game to be transmitted to the performance control board 41.

The special symbol fluctuation pattern information may include information specifying whether or not a specific advance notice performance (such as the "reach performance" or "pseudo consecutive performance" described below) occurs. In more detail, the special symbol fluctuation pattern is roughly divided into a "jackpot fluctuation pattern" in the case of a jackpot and a "miss fluctuation pattern" in the case of a miss, depending on the result of the jackpot lottery. These fluctuation patterns include, for example, a "reach fluctuation pattern" that specifies the occurrence of a reach performance, a "normal fluctuation pattern" that does not specify the occurrence of a reach performance, a "reach fluctuation pattern with pseudo consecutive performance" that specifies the occurrence (overlapping occurrence) of a pseudo consecutive performance and a reach performance, and a "normal fluctuation pattern without pseudo consecutive performance" that specifies the occurrence of a pseudo consecutive performance but does not specify the occurrence of a reach performance. Note that, in order to secure the performance time of the reach performance or pseudo consecutive performance, the fluctuation time of the fluctuation pattern that specifies the reach performance or pseudo consecutive performance is usually set to be longer than the normal fluctuation pattern.

Based on the information contained in the performance control commands (here, the variation pattern designation command and the decorative pattern designation command) sent from the main control board 40, the performance control board 41 determines the performance content (performance scenario such as preview performance) to be developed in a chronological order during the decorative pattern variation display game and the decorative pattern (decorative stop pattern) to be finally displayed, and executes the decorative pattern variation display game by displaying the decorative patterns in a variable manner according to a time schedule based on the variation pattern of the special patterns. As a result, the decorative patterns are displayed by the main liquid crystal display device 20M in a variable manner in time with the variable display of the special patterns by the special pattern display devices 22a and 22b, and the period of the special pattern variation display game and the period during the decorative pattern variation display game are substantially the same time width. In addition, the performance control board 41 controls the main liquid crystal display device 20M, the light display device 16a, or the sound generating device 17a in accordance with the performance scenario, and develops various performances in the decorative pattern variation display game. This allows the main LCD display device 20M to play images (image effects), play sound effects (sound effects), and turn on and off the decorative lamps 16 and LEDs (light effects).

In this way, the special symbol change display game and the decorative symbol change display game have an inseparable relationship, and the display result of the special symbol change display game is reflected in the decorative symbol change display game, so these two symbol change display games may be considered as equivalent symbol games. In this specification, unless otherwise necessary, the above two symbol change display games may be simply referred to as "symbol change display games."

(Regarding the reservation of general maps)
In the gaming machine 1, when a game ball passes through the normal pattern gate 26, that is, when a detection signal is input from the normal pattern gate detection sensor 26a, a random number related to the normal pattern variable display game (random number for determining whether a normal pattern is a hit) is obtained, and this random number is reserved and stored in the normal pattern reserved memory area of RAM 40c as reserved data up to a predetermined upper limit value, which is the maximum reserved memory number (for example, a maximum of 4).
The general map reservation memory area is provided with reservation 1 memory area to reservation n memory area (n is the maximum reservation memory number: in this embodiment, n = 4), and each can store the maximum number of reserved data. Note that there is no particular limit to the maximum number of reserved memories in the general map reservation memory area.
The game balls related to the reserved data stored in this reserved memory area are also called "reserved balls". In order to make the number of reserved balls clear to the player, a dot display corresponding to the number of reserved balls in the composite display device 22c is lit up, or a reserved display provided as an icon image on the screen of the liquid crystal display device 20 (the main liquid crystal display device 20M or the sub liquid crystal display device 20S) is lit up.

(Normal pattern change display game)
In the gaming machine 1, a "regular symbol winning lottery" is performed by random number lottery on the main control board 40 based on the passing of the game ball through the regular symbol gate 26. Based on the lottery result, the regular symbol represented by the LED is displayed variably on the composite display device 22d to start the regular symbol variable display game, and after a predetermined variable time has elapsed, the result is displayed as a combination of the LEDs being lit and not lit. For example, if the result of the regular symbol winning lottery is a "regular symbol winning", a specific LED on the composite display device 22d is displayed in a specific lighting state (for example, all two LEDs are lit, or the LED on the "○" side of the LEDs representing "○" and "×" is lit) according to the regular symbol winning type. In this embodiment, only one type of regular symbol winning type is provided.

When this "normal winning" occurs, the normal electric role solenoid 25a (see FIG. 4) is activated, the second start hole 24 is opened or enlarged to allow game balls to flow in easily (start hole open state), and a game state (hereinafter referred to as "normal open game") that is more advantageous to the player than when the second start hole 24 is closed is generated. In this normal open game, the winning area is opened or enlarged by the normal electric role 25 until the opening time of the second start hole 24 has elapsed for a predetermined time (e.g., 5.7 s) or until the number of game balls that have entered the second start hole 24 reaches a predetermined number (e.g., 10), and when either of these conditions is met, the second start hole 24 is closed. This operation is repeated a predetermined number of times (e.g., up to once).

[3.3 About the jackpot]
Next, the "jackpot" in the gaming machine 1 will be described.
In the gaming machine 1, for example, "4R1", "10R", and "4R2" are provided as jackpot types, and when the result of the jackpot lottery is "jackpot", a lottery for the jackpot type is held in the pattern lottery.
The above notation "R" means the prescribed number of rounds (maximum number of rounds).

The type of jackpot is the hit that triggers the activation of the conditional device. Here, a "conditional device" is a device whose operation is a necessary condition for the activation of the continuous device that operates the reels to play a round, and which is activated when a specific combination of special symbols is displayed or when the game ball passes through a specific area inside the jackpot opening.

In the jackpot game, after the pre-opening interval time (opening time) to notify the start of the jackpot game has elapsed, the first large prize winning port 27 or the second large prize winning port 28 is opened and a predetermined time (maximum opening time: for example, 29.8) has elapsed, or the number of game balls that have entered the first large prize winning port 27 or the second large prize winning port 28 has reached a predetermined number (maximum number of winnings), the first large prize winning port 27 or the second large prize winning port 28 is closed. This "round game" is repeated for a predetermined number of rounds (number of rounds based on the jackpot type). Then, after the specified number of rounds, when the post-opening interval time (ending time) to notify the end of the jackpot game has elapsed, the jackpot game ends. Note that the "s" after the number stands for "seconds."

When a jackpot game is executed, the game state after the jackpot game ends, the number of chance bonuses, and the number of time-saving bonuses are determined according to the game state at the time of winning the jackpot and the determined jackpot type.
The probability of the number of times of the special symbol variation display game is set when the game state after the big win game is a high probability state. In the gaming machine 1, the high probability state after the big win game continues until the number of times of the special symbol variation display game is the probability of the number of times of the special symbol variation display game, for example, 154 times, and when the special symbol variation display game of the probability of the number of times of the special symbol variation display game is ended without winning the big win in the big win lottery, the game state is set (transitioned) to the low probability state.
The number of time-saving times is set when the game state after the jackpot game is in the time-saving state. In the gaming machine 1, the time-saving state after the jackpot game continues until the number of times the special symbol variable display game is executed reaches the time-saving number (for example, 150 times), and when the special symbol variable display game reaches the time-saving number without winning the jackpot in the jackpot lottery, the game state is set (transitioned) to the non-time-saving state.
However, the gaming machine 1 may be a "general special probability machine" of the type in which the number of special probability periods and the number of time-saving periods continue until a jackpot is won in a jackpot lottery (until the next time).
In addition, the number of times the time is reduced may be the total number of times that the special pattern change display game 1 and the special pattern change display game 2 are played (the total number of changes in special pattern 1 and special pattern 2), or it may be the number of times that either one of them is played (for example, the number of times that the special pattern change display game 2 is played).

Here, in this embodiment, a plurality of loss types are provided for the "loss" as well as the jackpot types. Specifically, three loss types, "loss 1", "loss 2", and "loss 3", are provided.
As described above, if the result of the jackpot lottery is a "miss," a lottery for the type of miss is held in the symbol lottery.

[3.4 Production]
(Performance mode)
Next, the presentation mode (presentation state) will be described. The gaming machine 1 of this embodiment is provided with a plurality of presentation modes for producing presentations related to the game state, and is configured to be able to switch between the presentation modes. Specifically, a presentation mode corresponding to the set game state is provided. In each presentation mode, the background display as the background of the decorative pattern variable display screen is displayed with a different background presentation, so that the player can understand what game state he or she is currently in.

The presentation control board 41 (CPU 41a) has a functional section (presentation state transition control means) that controls transitions between multiple presentation modes. The presentation control board 41 (CPU 41a) is configured to grasp the current game state and control transitions between multiple presentation modes in a manner that maintains consistency with the game state managed by the main control board 40 based on specific presentation control commands sent from the main control board 40 (CPU 40a), specifically, presentation control commands including game state information managed by the main control board 40. Examples of the specific presentation control commands include a variation pattern designation command, a decorative design designation command, and a game state designation command sent when a change occurs in the game state.

(Preview performance)
Next, the advance notice performance will be explained. The performance control board 41 is configured to be able to control the appearance of various "advance notice performances" related to the current performance mode and the result of the big win lottery based on the contents of the performance control command from the main control board 40, specifically, based on at least the variation pattern information included in the variation pattern designation command. Such advance notice performances suggest (advance notice) the expectation of whether or not a big win type has been won (hereinafter referred to as "expectation of winning"), and act as "excitement performances" to stimulate the player's expectation of winning. Representative advance notice performances include "reach performances", "pseudo consecutive performances", and even "foreseeing advance notice performances". The performance control board 41 functions as an advance notice performance control means capable of controlling the execution (appearance) of these performances.

"Reach effect" refers to an effect mode that accompanies a reach state (variable display mode that accompanies a reach state: reach variation pattern), and more specifically, an effect mode that derives and displays the final game result via a reach state. Reach effects include multiple types of reach effects that are associated with the probability of winning. For example, there are some that have a relatively higher probability of winning compared to when a normal reach effect appears. Such reach effects are called 'super reach effects'. Many of these "super reaches" have a relatively longer performance time (variation time) than normal reaches to increase the expectation of winning. In addition, normal reaches and super reaches include multiple types of reach effects. Super reaches include multiple types of reach effects, namely Super Reach 1, 2, 3, and 4, and the winning expectation of these Super Reach 1 to 4 has the following relationship: "Super Reach 1 < Super Reach 2 < Super Reach 3 < Super Reach 4".

"Pseudo consecutive performance" refers to a performance mode that involves a pseudo continuous change display state (pseudo consecutive change) of decorative symbols, and "pseudo consecutive change" refers to a change display mode in which, during a decorative symbol change display game, some or all of the decorative symbols are temporarily put into a temporary stop state, and then the decorative symbols are changed again from that temporary stop state, and this display action is repeated once or multiple times. In this respect, it differs from the "preview notice performance (continuous notice performance)" described below, which is deployed across multiple symbol change display games. The occurrence rate (appearance rate) of such "pseudo consecutive" is basically set so that the more pseudo changes there are, the higher the chance of winning. For example, depending on the number of pseudo changes, it is easier to select a performance that stimulates anticipation, such as a super reach.

The term "pre-reading prediction effect" (hereinafter sometimes abbreviated as "pre-reading prediction" or "pre-reading effect") refers to a presentation that notifies the player of the possibility of being controlled to an advantageous state before the display of the pattern to be judged is changed based on the result of the pre-reading judgment. Note that the "advantageous state" refers to a state that is advantageous to the player.
Specifically, the pre-reading performance is performed for reserved balls (unconsumed reserved balls) that have not yet been used for the execution of the pattern change display game (the operation of displaying the variation of special patterns), mainly by using the reserved display mode and the background performance of the pattern change display game that is executed first, in a performance mode that can notify the winning expectation in advance before the reserved ball is used for the pattern change display game. In addition to the above-mentioned "reach performance", various performances such as the so-called "SU (step-up) notice performance", "timer notice performance", "revival performance", and "premiere notice performance" are generated in the pattern change display game to liven up the game content.

Here, with reference to Figure 5, we will explain the "hold change preview effect" as an example of the above-mentioned look-ahead preview effect.
In the case of the gaming machine 1 of this embodiment, the upper display area in the screen of the main liquid crystal display device 20M is provided with a display area (display area for displaying decorative pattern change display performance and advance notice performance) for displaying the decorative pattern change display game, and the lower display area in the screen is provided with a reserved display area 60 (reserved display section a1-d1) for displaying the reserved ball number on the special pattern 1 side and a reserved display area 61 (reserved display section a2-d2) for displaying the reserved ball number on the special pattern 2 side. The presence or absence of reserved balls is notified by a predetermined reserved display mode. FIG. 5 shows an example in which the presence or absence of reserved balls is indicated by a lit state (reserved balls: "○ (white circle)" in the figure) or an unlit state (no reserved balls: dashed circle in the figure), and information on the current reserved ball number is notified.

The display of the reserved balls (reserved display) is displayed in the order of occurrence (winning order), and in each reserved display area 60, 61, the reserved ball on the left side is displayed as the reserved ball that occurred first on the time axis (i.e., the oldest) among all reserved balls in the reserved display. In addition, on the left side of the reserved display area 60, 61, a changing display area 62 is provided to show the reserved balls currently being used in the special pattern change display game. In the case of this embodiment, the changing display area 62 is configured so that an image of the game execution reserved K icon currently being used in the game is displayed on the reception seat J icon. In other words, when the special pattern 1 or special pattern 2 change display starts, the icon (icon image) of the oldest reserved display part a1 or a2 displayed in the reserved display area 60, 61 moves to the reception seat J icon in the changing display area 62 as the game execution reserved K icon, and the state is maintained for a predetermined display time.

When a reserved ball is generated, the main control board 40 transmits to the performance control board 41 a "reserved addition command" which specifies the pre-reading judgment information related to the jackpot lottery result and the number of reserved balls at the time of the pre-reading judgment (the number of reserved balls currently existing, including the reserved ball generated this time).
In this embodiment, the above-mentioned reserve addition command is composed of two bytes, and the reserve addition command is composed of data on the upper byte side that enables the number of reserved balls at the time of the look-ahead judgment to be identified, and data on the lower byte side that enables the look-ahead judgment information to be identified.

As can be understood from the above description, in this embodiment, when a game ball enters the first start hole 23 or the second start hole 24 and a new reserved ball is generated, a jackpot lottery for the pattern change display game related to that reserved ball is performed as a pre-reading judgment. The main control board 40 reserves and stores the pre-reading judgment information obtained by such a pre-reading judgment in the corresponding memory area of the RAM 40c.

Here, the pre-reading judgment information is specifically game information obtained by pre-reading and judging the jackpot lottery result (jackpot lottery result at the start of the variation) executed when the reserved ball is provided to the pattern variation display game in the main control board 40 and the variation pattern at the start of the variation. That is, this information includes at least information that pre-reads and judges the jackpot lottery result at the start of the variation (pre-reading win/loss information), and can also include information that pre-reads and judges the pattern lottery result (pre-reading pattern information) and information that pre-reads and judges the variation pattern at the start of the variation (pre-reading variation pattern information). The information included in the reserved addition command to be sent to the performance control board 41 can be appropriately determined depending on the content to be notified in the pre-reading notice.
It is assumed that the pending addition command includes predictive win/loss information, predictive pattern information, and predictive fluctuation pattern information.

When the performance control board 41 receives the above-mentioned reserved addition command sent by the main control board 40, it performs performance control processing related to the "pre-reading preview performance" as part of the display control processing related to the above-mentioned reserved display, based on the look-ahead judgment information contained therein. Specifically, it performs a "pre-reading preview lottery" to draw whether or not the look-ahead preview performance can be executed, and if the draw is successful, it causes the look-ahead preview performance to appear.

The "pre-reading fluctuation pattern" obtained by the pre-reading judgment when the reserved ball is generated does not necessarily have to be the "fluctuation pattern at the start of fluctuation" obtained when the reserved ball is actually used for the fluctuation display operation. For example, to explain a representative case where the fluctuation pattern at the start of fluctuation is a fluctuation pattern that specifies "Super Reach 1", in this case, it is possible to specify that the content specified by the pre-reading fluctuation pattern is not the type of reach performance itself, "Super Reach 1", but rather its essential "Super Reach type".

In the case of this embodiment, if the pre-reading notice lottery is won, a "pending display change" pre-reading notice performance (also referred to as a "pending change notice") is performed in which the pending icon that is the subject of the pre-reading notice among the pending icons in the pending display sections a1 to d1 and a2 to d2 is changed from, for example, the normal pending display (normal pending display mode) in white to a pending display (special pending display mode) in a pre-reading display of blue, green, red, or a danger pattern (or a special color or pattern such as rainbow).
In Fig. 5, the reserved ball in the hatched reserved display section b1 is shown as a special reserved display. Here, the reserved icon blue, green, red, and danger pattern display indicate a high probability of winning, in that order, and the danger pattern reserved icon display is a premium reserved icon that indicates a very high probability of winning a jackpot.

(Direction Means)
Various effects in the gaming machine 1 are produced by the performance means arranged in the gaming machine 1. This performance means may be a stimulus transmission means capable of exerting a performance effect by appealing to human perceptions such as vision, hearing, and touch, and representative examples include light generating means (light display device 16a: light performance means) such as the decorative lamp 16 and the LED device, sound generating devices (sound generating device 17a: sound performance means) such as the speaker 17, performance display devices (display means) such as the main liquid crystal display device 20M and the sub liquid crystal display device 20S, a pressure device that transmits contact pressure to the operator's body, a wind pressure device that applies wind pressure to the player's body, and movable role objects that exert visual performance effects by their operation. Here, the performance display device is a display device that appeals to the visual sense like the image display device, but differs from the image display device in that it also includes those that do not rely on images (for example, 7-segment displays). When referred to as an image display device, it refers mainly to a type that produces a performance by displaying an image, and those that produce a performance by means other than images, such as 7-segment displays, are included in the concept of the performance display device.

<4. Board connection configuration>
The supply path of the power supply voltage to each board provided in the gaming machine 1 will be described.

Figure 6 is a power supply system diagram of the gaming machine 1. As shown in Figure 6, in addition to the main control board 40, performance control board 41, and payout control board 42 described above, the gaming machine 1 is equipped with a power supply board 70, a game ball dispenser connection terminal board 71, a relay board 72, and a power supply relay board 73.

The game ball lending device connection terminal board 71 is connected to the game ball lending device and transmits and receives various signals between the game ball lending device and the game ball lending device.

The main control board 40 is connected to the dispensing control board 42 via a transmission line H2. The dispensing control board 42 generates a backup power supply (VBB) that is supplied to the RAM 40c and the RAM of the integrated circuit IC7 (see FIG. 9) when the power is turned off based on a 5V DC voltage (DC5VA). The backup power supply (VBB) is supplied to the RAM 40c and the RAM of the integrated circuit IC7 when the power is turned off, making it possible to back up (retain) data stored in the RAM 40c and the RAM of the integrated circuit IC7 for a certain period of time (for example, one day or more).
The dispensing control board 42 supplies 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), 5V DC voltage (DC5VA) and backup power supply (VBB) to the main control board 40 via transmission line H2.

<5. Configuration of the dispensing control board>
[5.1 Structure of the dispensing control board]
Fig. 7 is a diagram showing the wiring pattern on the component side 42a of the dispensing control board 42. Fig. 8 is a diagram showing the wiring pattern on the solder side 42b of the dispensing control board 42. Fig. 9 is a layout diagram of electronic components on the dispensing control board 42. Note that Fig. 8 is a diagram that is inverted from left to right so that the connection relationship with Figs. 7 and 9 can be easily understood.
Fig. 10 is a diagram showing the diameters of the through holes provided in the dispensing control board 42. Fig. 11 is a diagram explaining the legend of the diameters shown in Fig. 10.
For ease of explanation, only a portion of the electronic components and wiring patterns mounted on the dispensing control board 42 will be described below.

As shown in Figures 7 and 8, the dispensing control board 42 is a double-sided board in which a ground pattern 42c is formed as a solid ground on the component side 42a, which is the front surface, and a solder side 42b, which is the back surface, and a plurality of conductive wiring patterns are formed on the same. As shown in Figures 10 and 11, the dispensing control board 42 has a plurality of through holes of different diameters formed therein, and the wiring patterns formed on the component side 42a and the solder side 42b are electrically connected via these through holes. Details of the wiring patterns and through holes will be described later.

In this embodiment, a "through hole" is a hole that penetrates the component surface 42a and the solder surface 42b and is plated with a conductor, and includes a through hole into which a terminal of an electronic component is inserted, a through hole via that electrically connects the wiring patterns of the component surface 42a and the solder surface 42b, etc.

As shown in FIG. 9, the dispensing control board 42 is equipped with multiple electronic components. All of the electronic devices are lead components, and the terminals (leads) of the electronic components arranged on the component surface 42a are inserted into the through holes and then soldered from the solder surface 42b to be fixed to the dispensing control board 42 and electrically connected to the wiring patterns formed on the component surface 42a and the solder surface 42b.

In this way, all electronic components of the payout control board 42 are arranged on one side, the component side 42a, and the component side 42a is attached to the back of the game board 5 so that it can be seen, so that the electronic components mounted on the payout control board 42 can be confirmed (visually) when the payout control board 42 is attached to the game board 5.

The electronic components include connectors CN (CN1-CN7), integrated circuits IC (IC1-IC22), resistors R (R1-R97), capacitors C (C1-C79), noise removal filters FLT (FLT1-FLT10), switches SW (SW1-SW4), and a 7-segment display FND (FND1). These electronic components are soldered and fixed to the dispensing control board 42 in the positions shown in Figure 9.

For example, the connector CN1 is connected to the transmission line end of the transmission line H1 (see FIG. 6) that connects to the power supply board 70. Therefore, various operating power sources (DC voltages) are supplied to the dispensing control board 42 via the connector CN1.
The connectors CN2 and CN6 are connected to the transmission line ends of the transmission lines H3 (see FIG. 6) that connect with the relay board 72.
The connector CN3 is connected to the transmission line end of the transmission line H2 (see FIG. 6) that connects to the main control board 40. Therefore, the dispensing control board 42 supplies (outputs) various operating power sources (DC voltages), backup power sources (VBB), and various signals to the main control board 40 via the connector CN3.
Connector CN4 is connected to the transmission line end of a transmission line that connects the game ball lending device connection terminal board 71, and transmits various signals between the payout control board 42 and the game ball lending device connection terminal board 71.

The 5V DC voltage (power supply voltage generated by the power supply board 70: DC5VA) output from the dispensing control board 42 has a maximum current capacity set to 1.0A and is mainly supplied to the main control board 40 (CPU 40a).

The 5V DC voltage output from the dispensing control board 42 (power supply voltage generated by the dispensing control board 42: DC5VH) has a maximum current capacity set to 1.0A and is mainly supplied to the handle volume and touch sensor.

The backup power supply (VBB) output from the dispensing control board 42 is mainly supplied to the main control board 40 (RAM 40c).

[5.5 12V DC voltage supply wiring]
Fig. 17 is a diagram of a combination of wiring patterns for 12V DC voltage (DC12VA). Fig. 17 is a diagram of a combination of the wiring pattern provided on the component surface 42a shown in Fig. 7, the wiring pattern provided on the solder surface 42b shown in Fig. 8, and the supply wiring for 12V DC voltage (DC12VA) from the 9th pin to the 12th pin (CN1_9 to CN1_12) of the connector CN1 to the 9th pin and the 11th pin (CN3_9, CN3_11) of the connector CN3 among the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

The 9th and 11th pins (CN3_9, CN3_11) of the connector CN3 are connected to the other end of the wiring pattern L12b_2.

Therefore, the 12V DC voltage (DC12VA) input to the four 9th to 12th pins (CN1_9 to CN1_12) of connector CN1 is supplied to the 9th and 11th pins (CN3_9, CN3_11) of connector CN3 through wiring patterns L12b_1, L12a_1, L12a_2, and L12b_2, and is output from the 9th and 11th pins (CN3_9, CN3_11) of connector CN3 to the main control board 40.

The seven-segment display FND1 can display performance information, similar to the performance indicator 34.

Furthermore, the 12V DC voltage (DC12VA) that has passed through the noise removal filter FLT2 is supplied to the integrated circuit IC1.
The integrated circuit IC1 is an LDO (Low Drop Out) regulator, and generates a 5V DC voltage (DC5VH) from the supplied 12V DC voltage (DC12VA). The 5V DC voltage (DC5VH) generated by the integrated circuit IC1 is supplied to the first pin (CN4_1) of the connector CN4 via the noise removal filter FLT9. As a result, the 5V DC voltage (DC5VH) is output to the game ball lending device via the first pin (CN4_1) of the connector CN4 and the game ball lending device connection terminal board 71.

In addition, the 5V DC voltage (DC5VH) generated by the integrated circuit IC1 also serves as the operating voltage for the volume sensor and the touch sensor.

Fig. 18 is a diagram of a combination of wiring patterns of 5V DC voltage (DC5VA). Fig. 18 is a diagram of a combination of the wiring pattern provided on the component surface 42a shown in Fig. 7, the wiring pattern provided on the solder surface 42b shown in Fig. 8, and the supply wiring of 5V DC voltage (DC5VA) from the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN1 to the 10th pin and the 12th pin (CN3_10, CN3_12) of the connector CN3 among the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

As shown in Figures 7 to 9, 13, 14, and 18, in the dispensing control board 42, a 5V DC voltage (DC5VA) is input from the power supply board 70 via the four 15th to 18th pins (CN1_15 to CN1_18) of the connector CN1.

The four 15th to 18th pins (CN1_15 to CN1_18) of connector CN1 are connected to one end of wiring pattern L5b_1 on solder surface 42b. The other end of wiring pattern L5b_1 is connected to one end of wiring pattern L5a_1 on component surface 42a via two through holes T5_1 to T5_2. The other end of wiring pattern L5a_1 is connected to the middle of wiring pattern L5b_2 on solder surface 42b via two through holes T5_3 to T5_4. The 10th and 12th pins (CN3_10, CN3_12) of connector CN3 are connected to one end of wiring pattern L5b_2.

Therefore, the 5V DC voltage (DC5VA) input to the four 15th to 18th pins (CN1_15 to CN1_18) of connector CN1 is supplied to the 10th and 12th pins (CN3_10, CN3_12) of connector CN3 through wiring patterns L5b_1, L5a_1, and L5b_2, and is output to the main control board 40 from the 10th and 12th pins (CN3_10, CN3_12) of connector CN3.

The other end of the wiring pattern L5b_2 is connected to a noise elimination filter FLT3, and the 5V DC voltage (DC5VA) that passes through the noise elimination filter FLT3 is supplied to the DC5VA monitoring circuit, the backup power generation circuit 80, etc., and is also supplied as an operating power source to each part (for example, integrated circuits IC2, IC7 to IC11, IC17) of the dispensing control board 42. The 5V DC voltage (DC5VA) is also used as a voltage for generating various control signals.

[5.7 Backup power supply wiring]
Fig. 19 is a diagram of a combination of the wiring patterns of the backup power supply (VBB). Fig. 19 is a diagram of a combination of the wiring patterns provided on the component surface 42a shown in Fig. 7, the wiring patterns provided on the solder surface 42b shown in Fig. 8, and the backup power supply wiring from the wiring pattern L5b_2 to the fourth pin and the sixth pin (CN3_4, CN3_6) of the connector CN3 among the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

7 to 9, 13, 14, and 19, one end of a wiring pattern L5b_3 on the solder surface 42b is connected to the other end of the wiring pattern L5b_2 via a noise removal filter FLT3. A backup power generation circuit 80 is connected to the middle of the wiring pattern L5b_3. The backup power generation circuit 80 includes a large-capacity electrolytic capacitor C13 and a diode D5.
The anode terminal of the diode D5 is connected to the middle of the wiring pattern L5b_3, and the cathode terminal is connected to one end of the wiring pattern LVb_1 on the solder surface 42b. The electrolytic capacitor C13 is a two-terminal capacitor, and the positive terminal (lead pin) is connected to the middle of the wiring pattern LVb_1, and the negative terminal (lead pin) is connected to the ground. Therefore, the electrolytic capacitor C13 stores electric charge as a backup power source (VBB) when a 5V DC voltage (DC5VA) is supplied, and when the 5V DC voltage (DC5VA) is no longer supplied (when the power is turned off), the electrolytic capacitor C13 outputs the backup power source (VBB) to the wiring pattern LVb_1.

One end of the wiring pattern LVb_2 is connected to the middle of the wiring pattern LVb_1 via a noise removal filter FLT4, and the other end of the wiring pattern LVb_2 is connected to the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3. As a result, the backup power supply VBB is output to the main control board 40 (RAM40c) via the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 and the transmission line H2.

In addition, as will be described in detail later, one end of the wiring pattern LVa_1 on the component surface 42a is connected to the other end of the wiring pattern LVb_1 via a through hole TB_1, and the backup power supply (VBB) that passes through the wiring pattern LVa_1 is supplied to the integrated circuit IC7 (RAM).

[5.8 Power Supply Wiring for Integrated Circuit IC7]
Fig. 20 is a composite diagram of the power supply wiring of the integrated circuit IC7. Fig. 20 is a composite diagram of the wiring pattern provided on the component surface 42a shown in Fig. 7, the wiring pattern provided on the solder surface 42b shown in Fig. 8, and the power supply wiring to the integrated circuit IC7 of the electronic components arranged on the dispensing control board 42 shown in Fig. 9.

As shown in Figures 7 to 9, 15, and 20, one end of the wiring pattern L5a_2 on the component surface 42a is connected to the middle of the wiring pattern L5b_3 via a through hole T5_5, and the other end of the wiring pattern L5a_2 is connected to the middle of the wiring pattern L5b_4 on the solder surface 42b via a through hole T5_6.

One end of the wiring pattern L5b_4 is connected to one end of the wiring pattern L5a_3 on the component surface 42a via a through hole T5_7, and one end of the wiring pattern L5a_3 is connected to one end of the wiring pattern L5b_5 on the solder surface 42b via a through hole T5_8. The other end of the wiring pattern L5b_5 is connected to one end of the wiring pattern L5a_4 on the component surface 42a via a through hole T5_9, and the other end of the wiring pattern L5a_4 is connected to the 52nd pin of the integrated circuit IC7.

The other end of wiring pattern L5b_4 is connected to the middle of wiring pattern L5a_5 on component surface 42a via through hole T5_10, and one end of wiring pattern L5b_6 is connected to the middle of wiring pattern L5a_5 via through hole T5_11. The other end of wiring pattern L5b_6 is connected to the 8th pin of integrated circuit IC7.

In addition, one end of the wiring pattern L5b_7 on the solder surface 42b is connected to the middle of the wiring pattern L5a_5 via a through hole T5_12. One end of the wiring pattern L5b_7 is connected to one end of the wiring pattern L5a_6 on the component surface 42a via a through hole T5_13. The other end of the wiring pattern L5a_6 is connected to the 19th pin of the integrated circuit IC7.

Therefore, integrated circuit IC7 is supplied with a 5V DC voltage (DC5VA) from pins 8, 19, and 52.

On the other hand, one end of the wiring pattern LVa_1 on the component surface 42a is connected to the other end of the wiring pattern LVa_1 via a through hole TB_1, and one end of the wiring pattern LVa_1 on the solder surface 42b is connected to the other end of the wiring pattern LVa_1 via a through hole TB2. One end of the wiring pattern LVb_4 is connected to the other end of the wiring pattern LVb_3 via a resistor R22. The other end of the wiring pattern LVb_4 is connected to the 20th pin of the integrated circuit IC7. Therefore, a backup power source (VBB) is supplied to the integrated circuit IC7 from the 20th pin.

The CPU of integrated circuit IC7 operates on 5V DC voltage (DC5VA) supplied from pins 8, 19, and 52, and controls each part of the payout control board 42, the launching device 44, and the game ball payout device 46 by expanding a program stored in ROM into RAM and executing it. For example, the CPU instructs the launching device 44 on the firing strength and instructs the game ball payout device 46 to pay out game balls.

The RAM of the integrated circuit IC7 temporarily stores data to instruct each part of the payout control board 42, the launch device 44, and the game ball payout device 46.

When the integrated circuit IC7 is powered off and no longer receives 5V DC voltage (DC5VA), the CPU stops operating and the backup power supply (VBB) is supplied via pin 20. In the integrated circuit IC, the data stored in the RAM is backed up (retained) by the backup power supply (VBB).

<6. Configuration example>
An example of the configuration of the gaming machine 1 will be described below.

The gaming machine 1 of the embodiment has the following (configuration A1-1).
(Configuration A1-1)
Gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board having an input connector to which a predetermined power supply voltage is input, a backup power generation circuit that generates backup power based on the predetermined power supply voltage, an output connector that outputs the backup power, a first wiring pattern that connects a terminal in the input connector to which the predetermined power supply voltage is input and the backup power generation circuit, and a second wiring pattern that connects the backup power generation circuit and a terminal in the output connector from which the backup power is output, the second wiring pattern being configured to be shorter than the first wiring pattern.

In the case of this (configuration A1-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply reduction corresponds to 5V DC voltage (DC5VA), the input connector corresponds to connector CN1, the backup power supply corresponds to backup power supply (VBB), the output connector corresponds to connector CN3, and the terminals to which the predetermined power supply voltage is input in the input connector correspond to the 15th to 18th pins (CN1_15 to CN1_18) of connector CN3. Also, the first wiring pattern corresponds to wiring patterns L5b_1, L5a_1, L5b_3, and LVb_1, and the second wiring pattern corresponds to wiring patterns LVb_1 and LVb_2.

As shown in Figures 18 to 20, when a 5V DC voltage (DC5VA) is input to the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN1, it is input to the two through holes T5_1 and T5_2 through the wiring pattern L5b_1 on the solder surface 42b. The 5V DC voltage (DC5VA) input to the two through holes T5_1 and T5_2 is led to the component surface 42a side through the through holes T5_1 and T5_2, and then input to the two through holes T5_3 and T5_4 through the wiring pattern L5a_1. The 5V DC voltage (DC5VA) input to the two through holes T5_3 and T5_4 is led to the solder surface 42b side through the through holes T5_3 and T5_4, and then input to the noise removal filter FLT3 through the wiring pattern L5b_2. The 5V DC voltage (DC5VA) input to the noise removal filter FLT3 is input to the anode terminal of diode D5 of the backup power generation circuit 80, output from the cathode terminal, and input to the positive terminal of electrolytic capacitor C13 through wiring pattern LVb_1. The total length of the wiring pattern through which the 5V DC voltage (DC5VA) passes from pins 15 to 18 (CN1_15 to CN1_18) of connector CN1 to the backup power generation circuit 80 (diode D5) is approximately 290 mm.

On the other hand, as shown in FIG. 19, the backup power supply (VBB) is generated by the backup power supply generating circuit 80 based on a 5V DC voltage (DC5VA) and stored in the electrolytic capacitor C13. When the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13 due to a power outage, the backup power supply (VBB) is input from the positive terminal of the electrolytic capacitor C13 through the wiring pattern LVb_1 on the solder surface 42b to the noise reduction filter FLT4. The backup power supply input to the noise reduction filter FLT4 is output to the main control board 40 from the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 through the wiring pattern LVb_2 on the solder surface 42b via the noise reduction filter FLT4. The total length of the wiring pattern through which the backup power supply (VBB) passes from the electrolytic capacitor C13 to the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 is about 56 mm.

Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is shorter than the total length (approximately 290 mm) of the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes. In this way, by making the wiring pattern of the backup power supply (VBB) output to the main control board 40 shorter than the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes, noise from the backup power supply (VBB) can be reduced and the stability of the backup of RAM 40c during a power outage can be improved.

Specifically, as shown in FIG. 9, on the dispensing control board 42, connectors CN1 and CN3 are arranged at positions spaced apart in the longitudinal direction (left-right direction), with connector CN1 at the top right and connector CN3 at the top left. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged slightly above and to the left of the dispensing control board 42, closer to connector CN3 than connector CN1 (directly below connector CN3).

In this way, by locating the backup power generation circuit 80 closer to connector CN3 than to connector CN1, it is possible to design the wiring patterns LVb_1 and LVb_2, through which the backup power supply (VBB) output to the main control board 40 passes, to be short in the dispensing control board 42. In this way, by shortening the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced and the stability of the backup of RAM 40c during a power outage can be improved.

Also, the diode D5 is disposed closer to the connector CN1 than the electrolytic capacitor C13. Furthermore, the diode D5 is disposed so that the anode terminal is closer to the connector CN1 than the cathode terminal. This allows the dispensing control board 42 to shorten the wiring pattern when connecting the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN1 and the diode D5 constituting the backup power supply generating circuit 80, thereby reducing the influence of noise on the wiring pattern through which the 5V DC voltage (DC5VA) passes.

In addition to (Configuration A1-1), the gaming machine 1 of the embodiment has the following (Configuration A1-2).
(Configuration A1-2)
The substrate includes a control circuit to which a backup power supply is input, and a third wiring pattern that connects the backup power supply generating circuit and the control circuit, and the second wiring pattern is configured to be shorter than the third wiring pattern.

In the case of this (configuration A1-2) concept, the control circuit corresponds to the integrated circuit IC7, and the third wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVB_3, and LVb_4.

As shown in FIG. 20, when the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13 due to a power outage, the backup power supply (VBB) is input from the positive terminal of the electrolytic capacitor C13 to the through hole TB_1 through the wiring pattern LVb_1 on the solder surface 42b. The backup power supply (VBB) input to the through hole TB_1 is led to the component surface 42a side via the through hole TB_1 and then input to the resistor R22 through the wiring pattern LVa_1. The backup power supply (VBB) input to the resistor R22 is input to the 20th pin of the integrated circuit IC7 through the wiring pattern LVb_4 via the resistor R22. The total length of the wiring pattern through which the backup power supply (VBB) passes from the electrolytic capacitor C13 to the 20th pin of the integrated circuit IC7 is approximately 228 mm.

Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is shorter than the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) input to the integrated circuit IC7 passes. In this way, by shortening the wiring pattern of the backup power supply (VBB) output to the main control board 40, it is possible to reduce noise entering the backup power supply (VBB) output to the main control board 40 and ensure that the RAM 40c is backed up when the power is turned off.

Specifically, as shown in FIG. 9, on the dispensing control board 42, the integrated circuit IC7 is located slightly below and to the left. The backup power generation circuit 80 is located closer to the connector CN3 than the integrated circuit IC7.

In this way, by locating the backup power generation circuit 80 closer to the connector CN3 than the integrated circuit IC7, it is possible to design the wiring patterns LVb_1, LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, to be short, in the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced, and the stability of the backup of RAM 40c during a power outage can be more reliably achieved.

In addition to (Configuration A1-1) and (Configuration A1-2), the gaming machine 1 of the embodiment has the following (Configuration A1-3).
(Configuration A1-3)
The output connector of the gaming machine 1 is configured to output a predetermined power supply voltage and a backup power supply.

In the case of this (configuration A1-3) concept, the connector CN3, which is an output connector, outputs 5V DC voltage (DC5VA) and backup power (VBB) to the main control board 40. In other words, the 5V DC voltage (DC5VA) input from the power supply board 70 is branched at the wiring pattern L5b_2, one of which is supplied directly to the 10th and 12th pins (CN3_10, CN3_12) of the connector CN3 and output to the main control board 40, and the other is supplied to the backup power generation circuit 80 to generate the backup power (see FIG. 19).

In such a case, one branch of the 5V DC voltage (DC5VA) is supplied to the connector CN3, and the other is supplied to the backup power supply generating circuit 80, so that the 5V DC voltage (DC5VA) can be branched near the connector CN3. Therefore, the wiring pattern (L5b_2) after branching can be shortened, and the wiring can be simplified.

The gaming machine 1 of the embodiment has the following (configuration A2-1).
(Configuration A2-1)
Gaming machine 1 is a gaming machine having a circuit board, the circuit board having an input connector to which a predetermined power supply voltage is input, a backup power generation circuit that generates a backup power supply based on the predetermined power supply voltage, a control circuit to which the backup power supply is input, a first wiring pattern that connects a terminal in the input connector to which the predetermined power supply voltage is input and the backup power generation circuit, and a second wiring pattern that connects the backup power generation circuit and the control circuit, the second wiring pattern being configured to be shorter than the first wiring pattern.

In the case of this (configuration A2-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply reduction corresponds to 5V DC voltage (DC5VA), the input connector corresponds to the connector CN1, the backup power supply corresponds to the backup power supply (VBB), the backup power supply generating circuit corresponds to the backup power supply generating circuit 80, and the control circuit corresponds to the integrated circuit IC7. Also, the first wiring pattern corresponds to the wiring patterns L5b_1, L5a_1, L5b_3, and LVb_1, and the second wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4.

As described above, the total length of the wiring pattern input from the main control board 40 to the backup power generation circuit 80, i.e., the total length of the wiring pattern through which a 5V DC voltage (DC5VA) passes from the 15th pin to the 18th pin (CN1_15 to CN1_18) of connector CN1 to the backup power generation circuit 80 (diode D5), is approximately 290 mm.

Also, when the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13 due to a power outage, the backup power supply (VBB) is input from the positive terminal of the electrolytic capacitor C13 to the through hole TB_1 through the wiring pattern LVb_1 on the solder surface 42b. The backup power supply (VBB) input to the through hole TB_1 is led to the component surface 42a side through the through hole TB_1 and then input to the through hole TB_2 through the wiring pattern LVa_1. The backup power supply (VBB) input to the through hole TB_2 is led to the solder surface 42b side through the through hole TB_2 and then input to the resistor R22 through the wiring pattern LVb_3. The backup power supply (VBB) input to the resistor R22 is input to the 20th pin of the integrated circuit IC7 through the resistor R22 and the wiring pattern LVb_4. The total length of the wiring pattern through which the backup power supply (VBB) passes from electrolytic capacitor C13 to pin 20 of integrated circuit IC7 is approximately 228 mm.

Therefore, the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) input to the integrated circuit IC7 passes is shorter than the total length (approximately 290 mm) of the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 to the backup power supply generating circuit 80 passes. In this way, by making the wiring pattern of the backup power supply (VBB) input to the integrated circuit IC7 shorter than the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 to the backup power supply generating circuit 80 passes, it is possible to reduce noise entering the backup power supply (VBB) and improve the stability of the RAM backup of the integrated circuit IC7 when the power supply is turned off.

Specifically, as shown in FIG. 9, on the dispensing control board 42, the connector CN1 is located at the top right, the backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located slightly above on the left side, and the integrated circuit IC7 is located slightly below on the left side. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located closer to the integrated circuit IC7 than the connector CN1.

In this way, by arranging the backup power generation circuit 80 closer to the integrated circuit IC7 than the connector CN1, it becomes possible to design the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power supply (VBB) input to the integrated circuit IC7 passes, to be short, in the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power supply (VBB) input to the integrated circuit IC7 passes, the effects of noise can be reduced, and the stability of the backup of the RAM of the integrated circuit IC7 during a power outage can be improved.

In addition to (Configuration A2-1), the gaming machine 1 of the embodiment has the following (Configuration A2-2).
(Configuration A2-2)
A first and a second power supply voltage, which are different voltages, are input to the input connector, and a third power supply voltage having the same voltage as the first power supply voltage is generated on the board based on the second power supply voltage, and the backup power supply generation circuit is configured to generate a backup power supply based on the first power supply voltage.

In the case of this (configuration A2-2) approach, the first power supply voltage corresponds to a 5V DC voltage (DC5VA), the second power supply voltage corresponds to a 12V DC voltage (DC12VA), and the third power supply voltage corresponds to a 5V DC voltage (DC5VH).

The 5V DC voltage (DC5VA) is supplied to the main control board 40, and is also supplied to components directly involved in controlling the game, such as generating various control signals such as a reset signal. On the other hand, the 5V DC voltage (DC5VH) is supplied to components not directly involved in controlling the game, such as the handle volume and touch sensor (components involved in firing).

Therefore, the 5V DC voltage (DC5VA) generated by the power supply board 70 realizes stable control of the parts directly related to the control of the game, and the 5V DC voltage (DC5VH) generated by the payout control board 42 operates the parts not directly related to the control of the game. This reduces the influence of the operating voltage supplied to the parts not directly related to the control of the game on the parts directly related to the control.

The gaming machine 1 of the embodiment has the following (configuration A3-1).
(Configuration A3-1)
The gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board comprising: a backup power generation circuit that generates backup power based on a predetermined power supply voltage; an output connector that outputs the backup power; a control circuit to which the backup power is input; a first wiring pattern that connects the backup power generation circuit to a terminal in the output connector from which the backup power is output; and a second wiring pattern that connects the backup power generation circuit to the control circuit, the first wiring pattern being shorter than the second wiring pattern.

In the case of this (configuration A3-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply reduction corresponds to 5V DC voltage (DC5VA), the backup power supply corresponds to the backup power supply (VBB), the output connector corresponds to the connector CN3, the backup power supply generating circuit corresponds to the backup power supply generating circuit 80, and the control circuit corresponds to the integrated circuit IC7. Also, the first wiring pattern corresponds to the wiring patterns LVb_1 and LVb_2, and the second wiring pattern corresponds to the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4.

As described above, the total length of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is approximately 56 mm, which is shorter than the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) supplied to the integrated circuit IC7 passes. In this way, by shortening the wiring pattern of the backup power supply (VBB) output to the main control board 40, it is possible to reduce noise input to the backup power supply (VBB) output to the main control board 40 and improve the stability of the backup of RAM 40c when the power is turned off.

Specifically, as shown in FIG. 9, on the dispensing control board 42, the connector CN3 is located at the upper left, the backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located slightly above on the left, and the integrated circuit IC7 is located slightly below on the left. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located closer to the connector CN3 than the integrated circuit IC7 (directly below the connector CN3).

In this way, by arranging the backup power generation circuit 80 closer to the connector CN3 than the integrated circuit IC7, it is possible to design the wiring patterns LVb_1, LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, to be short, in the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, the effects of noise can be reduced, and the stability of the backup of the RAM 40c during a power outage can be improved.

In addition to (Configuration A3-1), the gaming machine 1 of the embodiment has the following (Configuration A3-2).
(Configuration A3-2)
The substrate includes an input connector to which a predetermined power supply voltage is input, and a third wiring pattern that connects a terminal in the input connector to which the predetermined power supply voltage is input and a backup power generation circuit, and the third wiring pattern is configured to be longer than the second wiring pattern.

In the case of this (configuration A3-2) concept, the input connector corresponds to connector CN1, and the third wiring pattern corresponds to wiring patterns L5b_1, L5a_1, L5b_2, L5b_3, and LVb_1.

As described above, the length of the wiring pattern from connector CN1 to electrolytic capacitor C13 is approximately 290 mm, which is longer than the total length (approximately 228 mm) of the wiring pattern through which the backup power supply (VBB) supplied to integrated circuit IC7 passes. In this way, by shortening the wiring pattern of the backup power supply (VBB) input to integrated circuit IC7, it is possible to reduce noise entering the backup power supply (VBB) input to integrated circuit IC7 and improve the stability of the RAM backup of integrated circuit IC7.

Specifically, as shown in FIG. 9, the connector CN1 is located at the top right of the dispensing control board 42. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located closer to the integrated circuit IC7 than the connector CN1.

In this way, by arranging the backup power generation circuit 80 closer to the integrated circuit IC7 than the connector CN1, it becomes possible to design the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power supply (VBB) input to the integrated circuit IC7 passes, to be short, in the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1, LVa_1, LVb_3, and LVb_4 through which the backup power supply (VBB) input to the integrated circuit IC7 passes, the effects of noise can be reduced, and the stability of the backup of the RAM of the integrated circuit IC7 during a power outage can be improved.

In addition to (Configuration A3-1) and (Configuration A3-2), the gaming machine 1 of the embodiment has the following (Configuration A3-3).
(Configuration A3-3)
The backup power generation circuit includes a diode and a capacitor.
In the case of this (configuration A3-3) concept, the diode corresponds to the diode D5, and the capacitor corresponds to the electrolytic capacitor C13.

As a result, by avoiding electronic components such as batteries that may not be able to restore the original state if they deteriorate, and instead using electrolytic capacitor C13 which can be charged and whose performance does not change, as the electronic component that generates the backup power supply (VBB), it is possible to further improve the stability of the RAM backup of RAM 40c and integrated circuit IC7 which affect game play and ball output.

In addition to (Configuration A3-1) to (Configuration A3-3), the gaming machine 1 of the embodiment has the following (Configuration A3-4).
(Configuration A3-4)
The diode is configured to prevent reverse current from flowing through the backup power supply.

This makes it possible, with a simple configuration, to prevent the backup power supply (VBB) from flowing back into the wiring pattern of the 5V DC voltage (DC5VA) and affecting electronic components that operate on the 5V DC voltage (DC5VA). It also makes it possible to prevent the backup time of the RAM 40c and the RAM of the integrated circuit IC7 from being reduced due to the supply of the backup power supply (VBB).

In addition to (Configuration A3-3) to (Configuration A3-4), the gaming machine 1 of the embodiment has the following (Configuration A3-5).
(Configuration A3-5)
The diode is configured such that its cathode terminal is closer to the positive terminal of the capacitor than its anode terminal.

As shown in FIG. 9, diode D5 is arranged so that its cathode terminal is closer to the positive terminal of electrolytic capacitor C13 than its anode terminal. Also, electrolytic capacitor C13 is arranged so that its positive terminal is closer to the cathode terminal of diode D5 than its negative terminal. In other words, each electronic component is arranged on the dispensing control board 42 so that the distance between the positive terminal of electrolytic capacitor C13 and the cathode terminal of diode D5 is shorter than the distance between the negative terminal of electrolytic capacitor C13 and the cathode terminal of diode D5.

As a result, in the dispensing control board 42, the wiring pattern when connecting the electrolytic capacitor C13 and diode D5 that constitute the backup power generation circuit 80 can be shortened, further reducing the effects of noise.

The gaming machine 1 of the embodiment has the following (configuration B1-1).
(Configuration B1-1)
The gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board being supplied with a predetermined power supply voltage and equipped with a plurality of power lines having different maximum current capacities, and one or more through holes connecting the power lines formed on different layers of the circuit board, with a power line having a larger maximum current capacity being connected to a greater number of through holes than a power line having a smaller maximum current capacity.

In the case of this (configuration B1-1) concept, the board corresponds to the dispensing control board 42. Also, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_5 to T35_8.

Figure 21 is a diagram explaining the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Figure 21, wiring patterns L12b_1 and L12a_1 are supplied with a direct current voltage of 12V (DC12VA), have a line width (hereinafter simply referred to as width) of 5mm, and are set to a maximum current capacity of 5.0A. In addition, wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5mm.

The wiring patterns L12a_2 and L12b_2 are supplied with a direct current voltage of 12 V (DC12VA), have a width of 3 mm, and have a maximum current capacity set to 3.0 A. The wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), and the six through holes (T12_10 to T12_15) have a diameter of 0.5 mm.

The wiring patterns L35a_1 and L35b_2 are supplied with a direct current voltage of 35 V (DC35VA), have a width of 2 mm, and have a maximum current capacity set to 1.3 A. The wiring patterns L35a_1 and L35b_2 are connected via two through holes (T35_1 to T35_2), and the two through holes (T35_1 to T35_2) have a diameter of 0.5 mm.

Therefore, a combination of wiring patterns with a larger maximum current capacity has a larger number of connected through holes than a combination of wiring patterns with a smaller maximum current capacity.

In this way, by increasing the number of through holes connected to a combination of wiring patterns with a larger maximum current capacity, the electrical resistance in the through holes when current flows through a wiring pattern with a large current capacity can be reduced, and heat generation can be suppressed.

In addition to (Configuration B1-1), the gaming machine 1 of the embodiment has the following (Configuration B1-2).
(Configuration B1-2)
The plurality of power supply lines are configured to receive power supply voltages having different voltage values.

For example, the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9 shown in FIG. 21, and the combination of the wiring patterns L35a_1, L35b_1 and the through holes T35_5 to T35_8 are supplied with different power supply voltages (DC12VA, DC35VA).

In this way, even if the supplied power supply voltages are different, the greater the maximum current capacity of a combination of wiring patterns, the greater the number of connected through holes, thereby reducing the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount, and suppressing heat generation.

In addition to (Configuration B1-1) and (Configuration B1-2), the gaming machine 1 of the embodiment has the following (Configuration B1-3).
(Configuration B1-3)
A power supply line having a large maximum current capacity is configured to be wider than a power supply line having a small maximum current capacity.

As shown in Figure 21, the larger the maximum current capacity of a wiring pattern, the wider the wiring pattern.

In this way, by making the width of the wiring pattern wider for a combination of wiring patterns with a larger maximum current capacity, the electrical resistance when a current flows through the wiring pattern with a large current amount can be reduced, and heat generation can be suppressed.

The gaming machine 1 of the embodiment has the following (configuration B2-1).
(Configuration B2-1)
Gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board being supplied with a predetermined power supply voltage and equipped with one or more power supply lines having different maximum current capacities, and a plurality of through holes connecting the power supply lines formed on different layers of the circuit board, the power supply lines having the same power supply voltage but different maximum current capacities being configured to be connected with a different number of through holes.

In the case of this (configuration B2-1) concept, the board corresponds to the dispensing control board 42. Also, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, and the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15.

Figure 22 is a diagram explaining the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Figure 22, the wiring patterns L12b_1 and L12a_1 are supplied with a direct current voltage of 12V (DC12VA), have a width of 5mm, and have a maximum current capacity set to 5.0A. Furthermore, the wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5mm.

The wiring patterns L12a_2 and L12b_2 are supplied with a direct current voltage of 12 V (DC12VA), have a width of 3 mm, and have a maximum current capacity set to 3.0 A. The wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), and the six through holes (T12_10 to T12_15) have a diameter of 0.5 mm.

Therefore, even if the combination of wiring patterns is supplied with the same power supply voltage, the number of connected through holes will differ if the maximum current capacity is different.

In this way, even when a combination of wiring patterns is supplied with the same power supply voltage, by varying the number of connected through holes if the maximum current capacity is different, the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount can be reduced and heat generation can be suppressed.

In addition to (Configuration B2-1), the gaming machine 1 of the embodiment has the following (Configuration B2-2).
(Configuration B2-2)
A power supply line having a large maximum current capacity at the same power supply voltage is configured to be wider than a power supply line having a small maximum current capacity.

As shown in Figure 22, even if the power supply voltage is the same (DC 12VA), the width of the wiring pattern is wider for wiring patterns with a larger maximum current capacity.

In this way, even if the power supply voltage is the same, the width of the wiring pattern can be made wider for a combination of wiring patterns with a larger maximum current capacity, thereby reducing the electrical resistance when a current flows through the wiring pattern with a large current amount and suppressing heat generation.

The gaming machine 1 of the embodiment has the following (configuration B3-1).
(Configuration B3-1)
Gaming machine 1 is a gaming machine equipped with a board, the board having a power line to which a predetermined power supply voltage is supplied, and one or more through holes connecting the power lines formed on different layers of the board, the power line may branch into multiple lines, and the number of through holes connected to the power line before branching is greater than the number of through holes connected to the power line after branching.

In the case of this (configuration B3-1) concept, the board corresponds to the dispensing control board 42. Furthermore, the power lines before the branching and the through holes connecting the power lines correspond to the combination of wiring pattern L12a_1 and through holes T12_1 to T12_9. Furthermore, the power lines after the branching and the through holes connecting the power lines correspond to the combination of wiring pattern L12a_2 and through holes T12_10 to T12_15. Furthermore, as described above, wiring pattern L12a_1 branches into wiring patterns L12a_2 and L12a_3 midway.

As shown in FIG. 22, the wiring pattern L12a_1 before the branching is supplied with a direct current voltage of 12 V (DC12VA), has a width of 5 mm, and has a maximum current capacity set to 5.0 A. In addition, the wiring pattern L12a_1 before the branching is connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5 mm.

The branched wiring pattern L12a_2 is supplied with a direct current voltage of 12 V (DC12VA), has a width of 3 mm, and has a maximum current capacity of 3.0 A. The branched wiring pattern L12a_2 is connected via six through holes (T12_10 to T12_15), and the six through holes (T12_10 to T12_15) have a diameter of 0.5 mm.

Therefore, the number of through holes (9) connected to the wiring pattern L12a_1 before the branch is greater than the number of through holes (6) connected to the wiring pattern L12a_2 after the branch. In addition, the wiring pattern L12a_1 before the branch has a greater maximum current capacity than the wiring pattern L12a_2 after the branch.

In this way, by making the number of through holes connected to the wiring pattern L12a_1 before branching greater than the number of through holes connected to the wiring pattern L12a_2 after branching, the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount can be reduced, and heat generation can be suppressed.

In addition to (Configuration B3-1), the gaming machine 1 of the embodiment has the following (Configuration B3-2).
(Configuration B3-2)
The power line before the branch is configured to be wider than the power line after the branch.

The width (5 mm) of the wiring pattern L12a_1 before the branch is wider than the width (3 mm) of the power supply line after the branch. By making the width of the wiring pattern L12a_1 before the branch wider than the power supply line after the branch, it is possible to reduce electrical resistance when a current flows through a wiring pattern with a large current amount, and suppress heat generation.

The gaming machine 1 of the embodiment has the following (configuration B4-1).
(Configuration B4-1)
Gaming machine 1 is a gaming machine equipped with a circuit board, the circuit board having a plurality of power lines to which a predetermined power supply voltage is supplied, and one or more through holes connecting the power lines formed on different layers of the circuit board, and a power line connected to a smaller number of through holes is configured to be connected to a through hole having a larger diameter than a power line connected to a larger number of through holes.

In the case of this (configuration B4-1) concept, the board corresponds to the dispensing control board 42. Also, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L5b_1, L5a_1 and the through holes T5_1 to T5_2, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_5 to T35_8.

Figure 23 is a diagram explaining the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Figure 23, the wiring patterns L5b_1 and L5a_1 are supplied with a direct current voltage of 5V (DC5VA), have a width of 3mm, and have a maximum current capacity set to 2.5A. In addition, the wiring patterns L5b_1 and L5a_1 are connected via two through holes (T5_1-T5_2), and the two through holes (T5_1-T5_2) have a diameter of 0.8mm.

The wiring patterns L35a_1 and L35b_2 are supplied with a direct current voltage of 35 V (DC35VA), have a width of 2 mm, and have a maximum current capacity set to 1.3 A. The wiring patterns L35b_1 and L35a_1 are connected via four through holes (T35_1 to T35_4), and the four through holes (T35_1 to T35_2) have a diameter of 0.5 mm.

Therefore, the wiring patterns L5b_1 and L5a_1, which are connected to a smaller number of through holes, are connected to through holes with a larger diameter (through holes with a diameter of 0.8 mm) than the wiring patterns L35a_1 and L35b_2, which are connected to a larger number of through holes.

In this way, when the number of through holes to be connected is small and there is a risk of a large current flowing through one through hole, the diameter of the through hole can be increased to reduce the electrical resistance in the through hole and suppress heat generation.

The gaming machine 1 of the embodiment has the following (configuration B5-1).
(Configuration B5-1)
Gaming machine 1 is a gaming machine equipped with a board, the board being supplied with a predetermined power supply voltage and equipped with one or more power lines having different maximum current capacities, and a plurality of through holes connecting the power lines formed on different layers of the board, the through holes being configured so that the product of the diameter and number of the through holes is greater for a power line having a larger maximum current capacity than for a power line having a smaller maximum current capacity.

In the case of this (configuration B5-1) concept, the board corresponds to the dispensing control board 42. Also, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T5_15, and the combination of the wiring patterns L5b_1, L5a_1 and the through holes T5_1 to T5_2.

Figure 24 is a diagram explaining the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Figure 24, wiring patterns L12b_1 and L12a_1 are supplied with a direct current voltage of 12V (DC12VA), have a width of 5mm, and have a maximum current capacity set to 5.0A. Furthermore, wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), and the nine through holes (T12_1 to T12_9) have a diameter of 0.5mm. Therefore, in this case, the product of the diameter and the number of through holes is 4.5.

Furthermore, wiring patterns L12a_2 and L12b_2 are supplied with a direct current voltage of 12 V (DC12VA), have a width of 3 mm, and are set with a maximum current capacity of 3.0 A. Furthermore, wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), and the six through holes (T12_10 to T12_15) have a diameter of 0.5 mm. Therefore, in this case, the product of the diameter and the number of through holes is 3.0.

The wiring patterns L5b_1 and L5a_1 are supplied with a direct current voltage of 5V (DC5VA), have a width of 3mm, and have a maximum current capacity set to 2.5A. Furthermore, the wiring patterns L5b_1 and L5a_1 are connected via two through holes (T5_1-T5_2), each of which has a diameter of 0.8mm. Therefore, in this case, the product of the diameter and the number of through holes is 1.6.

In this way, wiring patterns with a larger maximum current capacity are connected to through holes with a larger product of the diameter and number of through holes than wiring patterns with a smaller maximum current capacity.

As a result, in a wiring pattern having a large maximum current capacity, the total surface area of the through holes can be increased, the electrical resistance in the through holes can be reduced, and heat generation can be suppressed.

The gaming machine 1 of the embodiment has the following (configuration C1-1).
(Configuration C1-1)
The gaming machine 1 has a substrate that is supplied with a predetermined power supply voltage and has a plurality of power supply lines with different maximum current capacities, and one or more vias that connect the power supply lines formed on different layers of the substrate, and is configured so that the number of vias connected by the power supply lines varies.

In the case of this (configuration C1-1) concept, the board corresponds to the dispensing control board 42. Also, the power supply lines and the through holes connecting the power supply lines correspond to the combination of the wiring patterns L12b_1, L12a_1 and the through holes T12_1 to T12_9, the combination of the wiring patterns L12a_2, L12b_2 and the through holes T12_10 to T12_15, and the combination of the wiring patterns L35a_1, L35b_2 and the through holes T35_1 to T35_4.

For example, as shown in FIG. 21, the number of through holes connected varies depending on the wiring pattern, so that the electrical resistance can be reduced when a current flows through a wiring pattern with a large current amount, thereby suppressing heat generation.

The above describes the embodiments, but each of the configuration examples from (Configuration A1-1) to (Configuration C1-1) can be combined in various ways, and by combining them in any way, a gaming machine 1 can be created that has the effects described in each configuration.
In addition, it is possible to combine the configurations and operations described in the embodiments.
Furthermore, the various illustrated specific examples are merely one mode for realizing each configuration. Various specific examples that are not specifically shown are also conceivable.
Furthermore, although the embodiment has been described using a pachinko gaming machine, the present invention can also be applied to reel-type gaming machines such as so-called slot gaming machines.
In such a reel-type gaming machine, the board configuration, circuit configuration, connector configuration, power supply configuration, etc., as described in each embodiment can be adopted.

The present invention can also be applied to a managed gaming machine in which gaming balls circulate within the gaming machine 1. In the case of a managed gaming machine, there is no need to supply AC input power (AC 24V) to the gaming ball lending device connection terminal board 71. There is no need to branch the transmission line H1 as shown in FIG. 6. However, if the power supply board 70 is also changed to stop supplying AC input power (AC 24V) to the gaming ball lending device connection terminal board 71, it is necessary to redesign the power supply board 70 and it is not possible to reuse the existing power supply board 70.

Therefore, in the managed gaming machine, as shown in Figures 25 to 28, AC input power (AC 24V) is input from pins 25 and 26 of connector CN1 of payout control board 42, and LED1 is turned on via bridge circuit DB1 and resistor R1. In this way, it becomes possible to use the same power supply board 70 as in the gaming machine 1 of the embodiment. This makes it possible to omit a new design and also to reuse the power supply board 70 that has been used up until now.

In addition, in the embodiment, a predetermined power supply voltage (e.g., 5V DC voltage (DC5VA)) is input from the power supply board 70 to the connector CN1 (input connector) of the dispensing control board 42. However, the supply source board that inputs the predetermined power supply voltage to the input connector is not limited to this, and may be a relay board provided between the power supply boards 70, or may be another board.

In addition, in the embodiment, a predetermined power supply voltage (e.g., 5V DC voltage (DC5VA)) and/or a backup power supply (in the embodiment, both) are output from connector CN3 (output connector) of payout control board 42 to main control board 40. However, the supply destination board that outputs the predetermined power supply voltage and/or the backup power supply is not limited to this, and may be, for example, a board such as performance control board 41 or launch control board 45.
