The plurality of speakers 17 allows for so-called stereophonic sound 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 attached in a ring shape as a board surface partition member to guide the launched game balls, 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 where game balls can flow down.

A liquid crystal display (LCD) 20 is provided in approximately the center of this game area 19. The liquid crystal display 20 is capable of performing variable display operations (variable display and stationary display) of multiple types of decorative patterns (e.g., left pattern (corresponding to the left display area), middle pattern (corresponding to the middle display area), 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).
This liquid crystal display device 20 displays various effects as images, in addition to the changing display operation of decorative symbols, under the control of an effect control board 41 described later.

In addition, a center ornament 21 is provided in the center of the game area 19, surrounding the display surface of the liquid crystal display device 20 at a distance. 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 game balls 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 approximately in the center of the play area 19, dividing 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 area for various functions, and is provided with a special symbol display device 22a and a special symbol display device 22b using dot displays.
The various function display sections including the special symbol display devices 22a and 22b are shown enlarged in FIG.

The special symbol display devices 22a and 22b execute a special symbol change display game by displaying the changing special symbols represented by the dot displays. The liquid crystal display device 20 then displays decorative symbols in a changing manner in time with the changing display of special symbols by the special symbol display devices 22a and 22b, executing a decorative symbol change display game together with various preview effects (effect images).

The various function display section also includes a composite display device 22c, which is composed of a dot display device similar to the special symbol displays 22a and 22b. It is called a composite because it is a reserved/time-saving/high-probability composite display device (hereinafter simply referred to as the "composite display device") with five display functions: displaying the first special symbol (hereinafter, the first special symbol will be referred to as "special symbol 1" and sometimes abbreviated as "special symbol 1"), the second special symbol (hereinafter, the second special symbol will be referred to as "special symbol 2" and sometimes abbreviated as "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 dot displays.
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, the composite display device 22d is configured to execute a normal symbol variable display game by a variable display operation of a normal symbol represented by one LED as a normal symbol display.
The composite display device 22d is also configured to display a right-hand hit indication using three LEDs. The right-hand hit indication 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, 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 opening 23 is a winning opening related to the starting conditions for the variable display operation of the special symbol 1 on the special symbol display device 22a, and is configured as a fixed starting opening without a starting opening opening/closing means (means for opening or enlarging the starting opening). 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.) within the game area 19, the first starting opening 23 is configured to be easy for game balls rolling through the left game area 19a to enter, but is configured to be difficult or impossible for game balls rolling through 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 the ordinary electric device 25.
The normal electric device 25 is controlled to an open state that allows game balls to enter the second starting hole 24, and a closed state that makes it difficult or impossible for game balls 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 through the right playing area 19b can enter the second starting hole 24, but game balls that have rolled through the left playing area 19a may also be able to enter the second starting hole 24.

Furthermore, above the second starting opening 24, that is, above the middle of the right playing area 19b, there is provided a normal symbol gate 26 through which game balls can pass. This normal symbol gate 26 is a winning opening related to the variable display operation of the normal symbol on the composite display device 22d, and inside it is provided a normal symbol gate detection sensor 26a (see Figure 4) that detects game balls passing through. Note that in this embodiment, the normal symbol gate 26 is provided only in the right playing area 19b, and only game balls that have rolled through the right playing area 19b can enter. However, the present invention is not limited to this, and the normal symbol gate 26 may be provided only in the left playing 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 positioned so that 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 positioned 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.
Inside the first large prize opening 27 and the second large prize opening 28, there are provided first large prize opening detection sensors 27a and second large prize opening detection sensors 28a (see Figure 4), respectively, which detect the passage of game balls.

In addition, multiple general winning openings 31 are provided on the left and right lower sides of the game area 19, and each has a general winning opening detection sensor 31a (see Figure 4) inside it that detects the passage of game balls.
Additionally, within the area of the game board, movable devices (not shown) that create 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 starting hole 23, one for the second starting 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 through the outlet 32.

2. Control configuration of gaming machine
Fig. 4 is a block diagram showing the control configuration of the gaming machine 1. The configuration (control configuration) for realizing the gaming 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 that describes the 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, they form a microcomputer.

Although not shown, the main control board 40 also includes a CTC (Counter Timer Circuit) for implementing periodic interrupts, a function for generating pulse outputs at regular intervals (bit rate generator), and time measurement functions; an interrupt controller circuit that performs interrupt enable/disable functions such as timer interrupts that issue interrupt signals to the CPU 40a; a reset circuit that detects power-on/power-off and power supply abnormalities and outputs a system reset signal to reset the CPU 40a; a watchdog timer (WDT) circuit that monitors for abnormal operation of the control program; an IAT (Inhibit Outside Designated Area) circuit that monitors whether the program is being executed correctly within a preset address range; and a counter circuit for generating random numbers within a certain range using 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 predetermined timing, and functions as a 16-bit counter as a whole. The CPU 40a sends instructions to the sampling circuit depending on the processing status, thereby obtaining the number indicated by the random number generation circuit as a random number (0 to 65535) for determining whether or not there is a jackpot, and using this random number for determining whether or not there is a jackpot. Note that, to prevent cheating, such as targeting a jackpot, the random number for determining whether or not there is a jackpot is obtained by adding a software random number generated by appropriate software processing to a hard random number.

Connected to the main control board 40 are a first start gate detection sensor 23a that detects game balls entering the first start gate 23, a second start gate detection sensor 24a that detects game balls entering the second start gate 24, a normal symbol gate detection sensor 26a that detects game balls passing through the normal symbol gate 26, a first large prize gate detection sensor 27a that detects game balls entering the first large prize gate 27, a second large prize gate detection sensor 28a that detects game balls entering the second large prize gate 28, a general prize gate detection sensor 31a that detects game balls entering the general prize gate 31, and an OUT monitoring sensor 32a that detects game balls (out balls) ejected from the play area 19. The main control board 40 is capable of receiving detection signals output from these sensors. Therefore, the main control board 40 can determine which winning slot the gaming 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 control signals for controlling the display of the special symbols 1 and 2.
The composite display device 22c and the composite display device 22d are also 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 main control board 40 is connected to a performance indicator 34 .
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, which will be described later. The performance indicator 34 is mounted, for example, on the main control board 40 or the dispensing control board 42 in an easily visible position.
The main control board 40 is capable of transmitting a control signal to the performance display 34 to cause the performance information to be displayed.

A 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 specifying the number of prize balls) can be sent to the payout control board 42.

In addition, an external centralized terminal board 43 for the frame 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, prize ball number 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 roles of this payout control board 42 are 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 equipped 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 these detection signals. The game ball payout device 46 is also equipped with a payout motor 46c that drives a ball payout mechanism (not shown) to pay out game balls, and the payout control board 42 is capable of sending a control signal to control the payout motor 46c.

Connected to the payout control board 42 are 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, front door open sensor 48, out-of-supply detection sensor 46a, and ball count sensor 46b. These status signals include a ball jam signal indicating a full state, a door open signal indicating that at least the front frame 2 is open, an out-of-supply signal indicating a shortage of game balls from the game ball payout device 46, a count error signal indicating a shortage of prize balls paid out or an abnormality in the ball count sensor 46b, and a payout completion signal indicating the completion of the payout operation. 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 (out-of-supply error), and the full state of the upper tray 10 (ball jam error).

The payout control board 42 is also capable of transmitting an authorization signal to the launch control board 45 to permit launch. Based on the authorization signal output from the payout control board 42, the launch control board 45 controls the energization of a launch solenoid (not shown) provided in the launch device 44, thereby realizing the launch of a game ball by operating the launch operation handle 15. Specifically, the launch of a game ball is permitted under the following conditions: a launch authorization signal is output from the payout control board 42 (launch authorization signal ON state), a touch sensor (not shown) provided on the launch operation handle 15 detects that the player is touching the handle, and a launch stop switch (not shown) provided on the launch operation handle 15 has not been operated. Therefore, when the launch authorization signal is not output (launch authorization signal OFF state), operating the launch operation handle 15 does not execute the launch operation, and no game ball is launched. Furthermore, the launch strength of the game ball can be changed depending on 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.

(Performance display)
The main control board 40 is capable of transmitting a control signal to the performance display 34 to cause the performance display 34 to display predetermined performance information.
Performance information is information that pachinko halls and relevant authorities want to confirm, and typical examples include information regarding the presence or absence of illegal prize ball cheating, such as excessive prize balls in the gaming machine 1, and the original ball-out performance of the gaming machine 1. Therefore, unlike preview effects, the performance information itself is information that is not directly related to the progress of the game itself when a player is enjoying the game.

For this reason, the performance indicator 34 is located 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 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 balls discharged from the game area 19 during the specific state (number of balls discharged during a specific state: β) can be adopted as performance information.
The above "total number of payouts" refers to the total number of game balls (prize balls) paid out when game balls enter (win) the winning slots (first start slot 23, second start slot 24, general winning slot 31, first large winning slot 27, second large winning slot 28).
Furthermore, the state to be adopted as the specific state can be determined appropriately depending on the state under which performance information is desired to be grasped. In the case of this embodiment, any of a plurality of game states and a state during a jackpot game can be adopted. Furthermore, multiple types of states may be used as the measurement target. For example, all game states except for a jackpot game can be used, and the type to be measured can be determined appropriately.
Alternatively, 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 of each winning port.

(2) Alternatively, it is also possible to measure only the total number of balls paid out, the total number of balls paid out excluding specific winning slots, or the total number of balls thrown out, and use the measurement results as performance information.

In this embodiment, the total number of dispensed balls during normal operation (number of dispensed balls under normal operation) and the total number of balls out during normal operation (number of balls out under normal operation) are measured in real time, and the value obtained by dividing the number of dispensed balls under normal operation by the number of balls out under normal operation and multiplying this value by 100 (the value calculated by dividing the number of dispensed balls under normal operation by the number of balls out under normal operation x 100) is displayed as performance information (hereinafter referred to as "normal operation ratio information"). Note that the displayed value in this case is rounded to one decimal place.
Therefore, the data on the number of payouts during normal play, the number of out balls during normal play, and the normal play ratio information are stored (memorized) in the corresponding areas of RAM 40c (the storage area for the total number of prize balls during specific play, the storage area for the number of out balls during specific play, and the specific ratio information storage area). However, rather than simply measuring continuously and displaying performance information, measurement is temporarily terminated when the total number of out balls reaches a predetermined number (e.g., 60,000). This specified number does not refer to the total number of out balls during normal play, but rather to the total number of out balls during all play states (including win play) (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 areas of RAM 40c (the storage area for the number of out balls in all states). For ease of explanation, the storage area for the total number of prize balls during specific play, the storage area for the number of out balls during specific play, the specific ratio information storage area, and the storage area for the number of out balls in all states will be abbreviated as the "measurement information storage area."

The normal time ratio information at the end point 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 balls dispensed during normal time, number of balls out during normal time, and number of balls out under all conditions) is cleared before measurement begins again (measurement of number of balls dispensed during normal time, number of balls out during normal time, normal time ratio information, and number of balls out under all conditions begins). 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 this 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 before), and the number of previous times of information to display can be determined as appropriate.

(Performance control command)
Depending on the processing status, the main control board 40 can transmit various presentation control commands, including information about the special symbol variation display game and information about errors, to the presentation control board 41. However, in order to prevent fraudulent activities 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 its function using a two-byte structure consisting of a one-byte mode (MODE) and a one-byte event (EVENT). To distinguish between MODE and EVENT, Bit 7 of MODE is set ON and Bit 7 of EVENT is set OFF. When this information is transmitted as valid, a strobe signal is output corresponding to each 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 reliably.

[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 issues an interrupt signal to the CPU 41a, an RTC (Real Time Clock) function unit, a reset circuit, etc., 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 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 LCD display device 20 (main LCD display device 20M, sub LCD display device 20S), the light display device 16a, the sound generating device 17a, and movable role devices (not shown).

The ROM 41b stores a control program for the performance operation by the CPU 41a and various data required for performance operation control.
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 roles of this performance control board 41 are to receive performance control commands from the main control board 40, select and determine performances based on the performance control commands, control the display of the LCD display device 20 (supply display data), control the audio output of the sound generator 17a, control the light emission of the optical display device 16a, and control the operation of the movable role object (drive control of the movable role object motor 50).

This performance control board 41 also functions as a control device for the liquid crystal display device 20, so 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 that controls the overall video output process, such as image development and image drawing.
The image ROM refers to a memory that stores image data that is subjected to image development processing by the VDP.
The VRAM is an image memory area that temporarily stores image data developed 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, thereby displaying various performance images 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 unit for an audio generating device 17 a including multiple speakers 17 , and the audio signals output by the audio control unit are amplified by an amplifier unit 17 b and supplied to the speakers 17 .
Also connected to the performance control board 41 are 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 are connected to the performance control board 41 to monitor the operation of the movable props.
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 Figure 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.
The performance control board 41 also controls the operation mode of the movable role object while monitoring its current operating position (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 for malfunctions in the operation of the movable role object based on the detection information from the position detection sensor 52, and if a malfunction occurs, detects it as an error.

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

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 Figure 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 pre-prepared performance patterns, and controls various performance means at the required timing to produce the desired performance. This results in the display of a performance image on the LCD display device 20 corresponding to the performance pattern, the playback of sound from the speaker 17, and the lighting and flashing of the decorative lamps 16. A "performance scenario" in the broadest sense is realized by the chronological unfolding of various performance patterns (such as decorative symbol variation display operations and preview performances).

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 processing based on the input of the above-mentioned strobe signal, and in the interrupt processing realized thereby, 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, the CPU 41a interrupts the interrupt processing based on another interrupt (timer interrupt processing executed periodically) even if that processing is in progress, 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 outline of the gaming operation of the gaming machine 1 realized by the above-described 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 jackpot game, which is a special gaming state. To facilitate understanding of this embodiment, the various gaming states will first be described.

Game play on the gaming machine 1 progresses in one of two game states, combining 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-shortening state is a state in which it is relatively difficult for a gaming ball to enter the second starting hole 24, and the time-shortening state is a state in which it is relatively easy for a gaming ball to enter the second starting hole 24. For example, the opening time of the second starting hole 24 when the regular winning lottery is won is set longer in the time-shortening state than in the non-time-shortening state. However, if it is easier for a gaming ball to enter the second starting hole 24 in the time-shortening state than in the non-time-shortening state, the time-shortening state may, for example, have a higher probability of winning the regular winning lottery or a shorter fluctuation time for the regular symbols than in the non-time-shortening 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 reserve memory area is provided with special symbol reserve memory areas corresponding to the special symbol 1 side and the special symbol 2 side, that is, a special symbol 1 reserve memory area and a special symbol 2 reserve 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 is capable of storing reserved data up to the maximum number of reserved memories. Note that there is no particular limit on the maximum reserved memory numbers of the special symbol 1 reserved memory area and the special symbol 2 reserved memory area. In addition, all or part of the maximum reserved memory numbers for each symbol may be different, and the number can be determined appropriately depending on the gameplay.
The game balls related to the reserved data stored in this special symbol reserved memory area are also called “reserved balls.” To make the number of reserved balls clear to the player, dot displays corresponding to the number of reserved balls of special symbol 1 and special symbol 2 on the composite display device 22c are lit, or a reserved display provided as an icon image on the screen of the liquid crystal display device 20 (main liquid crystal display device 20M or sub liquid crystal display device 20S) is lit.

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

In this embodiment, the lottery for a jackpot for special pattern 1 based on a winning entry into the first starting hole 23 and the lottery for a jackpot for special pattern 2 based on a winning entry into the second starting hole 24 are conducted separately and independently. Therefore, the result of the lottery for a jackpot for special pattern 1 is displayed on the special pattern display device 22a, and the result of the lottery for a jackpot for special pattern 2 is displayed on the special pattern display device 22b. Specifically, on the condition that a gaming ball has entered the first starting hole 23, the special pattern display device 22a displays a variable special pattern 1 to start the first special pattern variable display game. On the other hand, on the condition that a gaming ball has entered the second starting hole 24, the special pattern display device 22b displays a variable special pattern 2 to start the second special pattern 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, if the jackpot lottery result is a "jackpot", the special pattern being displayed is displayed as a static symbol in a predetermined "jackpot" mode, or in a predetermined "miss" mode 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."

If the result of the jackpot lottery is a "jackpot," that is, if the special pattern change display game ends and as a result the 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) occurs that is more advantageous to the player than during the special pattern change display game.

(Decorative pattern changing display game)
Furthermore, when the special symbol variation display game is started, the decorative symbol variation display game is started by variably displaying decorative symbols (game symbols for dramatic effects) on the main liquid crystal display device 20M, and various effects are developed in association with this. When the special symbol variation display game ends, the decorative symbol variation display game also ends, and predetermined special symbols indicating the results of the jackpot lottery are displayed on the special symbol display devices 22a and 22b, and decorative symbols reflecting the results of the jackpot lottery are derived and displayed on the main liquid crystal display device 20M. In other words, the results of the special symbol variation display game are reflected and displayed by the decorative symbol variation display game for dramatic effects, including the variably displaying operation of the decorative symbols.

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

Regarding the information required 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 results of the lottery.
In the symbol lottery, if the result of the jackpot lottery is a "jackpot," one of multiple jackpot types will be selected by lottery, and if it is a "miss," one of 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 selection may be made 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 jackpot lottery and the variation time of the special symbol)) to the presentation control board 41 as a presentation control command that specifies the processing state. As a result, basic information required for the decorative symbol variation display game is sent to the presentation control board 41.

The special symbol fluctuation pattern information can include information specifying whether or not a specific preview effect (such as a "reach effect" or "pseudo consecutive effects," described below) will occur. Specifically, the special symbol fluctuation patterns are broadly divided into "jackpot fluctuation patterns" for jackpots and "miss fluctuation patterns" for misses, depending on the jackpot lottery results. These fluctuation patterns include multiple types of fluctuation patterns, such as a "reach fluctuation pattern" that specifies the occurrence of a reach effect, a "normal fluctuation pattern" that does not specify the occurrence of a reach effect, a "reach fluctuation pattern with pseudo consecutive effects" that specifies the occurrence (overlapping occurrence) of a pseudo consecutive effect and a reach effect, and a "normal fluctuation pattern without pseudo consecutive effects" that specifies the occurrence of a pseudo consecutive effect but not a reach effect. Note that, in order to ensure the duration of the reach effect and pseudo consecutive effects, fluctuation patterns that specify reach effects or pseudo consecutive effects are usually set to have longer fluctuation times than normal fluctuation patterns.

Based on information contained in the presentation control commands (here, variation pattern designation commands and decorative symbol designation commands) sent from the main control board 40, the presentation control board 41 determines the presentation content (presentation scenario, such as preview presentations) to be developed chronologically during the decorative symbol variation display game, as well as the decorative symbols (decorative stop symbols) to be ultimately displayed. The presentation control board 41 then executes the decorative symbol variation display game by displaying the decorative symbols in a varying manner according to a time schedule based on the special symbol variation pattern. As a result, the decorative symbols displayed by the main LCD display device 20M are displayed in a varying manner in time with the display of the special symbols in the special symbol display devices 22a and 22b, so that the duration of the special symbol variation display game and the duration of the decorative symbol variation display game are substantially the same. Furthermore, the presentation control board 41 controls the main LCD display device 20M, the light display device 16a, or the sound generating device 17a, respectively, in accordance with the presentation scenario, to develop various presentations in the decorative symbol variation display game. This allows the main LCD display device 20M to play images (image effects), play sound effects (sound effects), and light up and flash (light effects) decorative lamps 16, LEDs, etc.

In this way, the special symbol variation display game and the decorative symbol variation display game have an inseparable relationship, and the display results of the special symbol variation display game are reflected in the decorative symbol variation display game, so these two symbol variation display games can be considered as equivalent symbol games. In this specification, unless otherwise necessary, the above two symbol variation display games may be simply referred to as "pattern variation 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 change display game (random number for determining whether a normal pattern is a hit) is obtained, and this random number is held as reserved data and stored in the normal pattern reserve memory area of RAM 40c up to a predetermined upper limit value, which is the maximum number of reserved memories (for example, a maximum of 4).
The general map reserve memory area has reserve 1 memory area to reserve n memory area (n is the maximum number of reserved memories: in this embodiment, n = 4), and each can store the maximum number of reserved memories. There is no particular limit to the maximum number of reserved memories in the general map reserve memory area.
The game balls related to the reserved data stored in this reserved memory area are also called “reserved balls.” To make the number of reserved balls clear to the player, a dot indicator corresponding to the number of reserved balls on the composite display 22c is lit, or a reserved indicator provided as an icon image on the screen of the liquid crystal display device 20 (main liquid crystal display device 20M or sub liquid crystal display device 20S) is lit.

(Normal symbol 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 a gaming ball through the regular symbol gate 26. Based on the result of this lottery, the regular symbol represented by the LED is displayed variably on the composite display device 22d, starting the regular symbol variable display game. After a predetermined variable time has elapsed, the result is displayed as a static combination of lit and unlit LEDs. For example, if the result of the regular symbol winning lottery is a "regular symbol winning," specific LEDs on the composite display device 22d are displayed in a specific lighting state (e.g., both LEDs are lit, or the LED representing a "circle" and an "x" is lit) depending on the type of regular symbol winning. Note that in this embodiment, only one type of regular symbol winning is provided.

When this "normal win" occurs, the normal electric device solenoid 25a (see FIG. 4) is activated, opening or enlarging the second start hole 24 to allow game balls to flow in more easily (start hole open state), creating a game state (hereinafter referred to as "normal electric open game") that is more advantageous to the player than when the second start hole 24 is closed. In this normal electric open game, the winning area is opened or enlarged by the normal electric device 25 until the opening time of the second start hole 24 has elapsed for a predetermined time (e.g., 5.7 seconds) 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, and 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 explained.
In the gaming machine 1, for example, "4R1", "10R", and "4R2" are provided as jackpot types, and if 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 specified 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 activation is a necessary condition for the activation of the consecutive device that operates to play a round of games, and is activated when a specific combination of special symbols is displayed or when the game ball passes through a specific area within the jackpot opening.

The jackpot game begins after a pre-opening interval (opening time) has elapsed to notify the player that a jackpot game is about to begin. Then, when a predetermined time (maximum opening time: e.g., 29.8) has elapsed since the first or second major prize opening 27 or 28 was opened, or when the number of game balls entering the first or second major prize opening 27 or 28 reaches a predetermined number (maximum number of wins), the first or second major prize opening 27 or 28 is closed. This "round game" is repeated for a predetermined number of rounds (the number of rounds depends on the type of jackpot). Then, after the predetermined number of rounds, a post-opening interval (ending time) has elapsed to notify the player that the jackpot game is about to end, and the jackpot game ends. 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 variations, and the number of time reduction variations are determined according to the game state at the time of winning the jackpot and the determined type of jackpot.
The number of chance variations is set when the gaming state after a jackpot game is a high probability state. In the gaming machine 1, the high probability state after a jackpot game continues until the number of times the special symbol variation display game is executed reaches the chance variation number (for example, 154 times), and when the special symbol variation display game reaches the chance variation number without winning a jackpot in the jackpot lottery, the gaming state is set (transitioned) to a low probability state.
The number of time-saving times is set when the game state after a jackpot game is in the time-saving state. In the gaming machine 1, the time-saving state after a 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 a jackpot in the jackpot lottery, the game state is set (transitioned) to the non-time-saving state.
However, the gaming machine 1 may also be a "general probability variation machine" of the type in which the number of probability variations and the number of time-saving variations continue until a jackpot is won in the jackpot lottery (until the next time).
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 executed (the total number of times that the special pattern change display game 1 and the special pattern change display game 2 are executed), or it may be the number of times that either one of the games is executed (for example, the number of times that the special pattern change display game 2 is executed).

In this embodiment, similarly to the jackpot types, there are multiple loss types for the "loss." Specifically, there are three loss types: "loss 1,""loss2," and "loss 3."
As described above, if the result of the jackpot lottery is a "miss," a lottery for the type of miss is held in the pattern lottery.

[3.4 Production]
(Performance mode)
Next, the presentation modes (presentation states) will be explained. 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 these 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, allowing the player to understand what game state they are currently in.

The presentation control board 41 (CPU 41a) has a functional unit (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 that include game state information managed by the main control board 40. Examples of such specific presentation control commands include a variation pattern designation command, a decorative symbol designation command, and a game state designation command sent when a change occurs in the game state.

(Preview performance)
Next, the preview effects will be explained. The effect control board 41 is configured to be able to control the appearance of various "preview effects" related to the current presentation mode and the jackpot lottery results based on the content of the presentation 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 preview effects suggest (predict) the expected probability of winning a particular jackpot type (hereinafter referred to as "win expectation probability") and act as "hype effects" to heighten the player's anticipation of winning. Typical preview effects include "reach effects,""pseudo consecutive effects," and even "predictive preview effects." The effect control board 41 functions as a preview effect control means capable of controlling the execution (appearance) of these effects.

A "reach effect" refers to an effect mode that accompanies a reach state (a variable display mode that accompanies a reach state: a reach fluctuation pattern). Specifically, it refers to an effect mode that derives and displays the final game result after going through a reach state. Reach effects include multiple types of reach effects that are associated with the likelihood of winning. For example, there are some that have a relatively higher likelihood 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 (fluctuation time) than normal reaches, in order to increase the expectation of winning. Furthermore, normal reaches and super reaches include multiple types of reach effects. Super reaches include multiple types of reach effects: Super Reach 1, 2, 3, and 4, and the expectation of winning for these Super Reaches 1 to 4 is related as follows: Super Reach 1 < Super Reach 2 < Super Reach 3 < Super Reach 4.

A "pseudo consecutive display" refers to a display mode that involves a pseudo continuous change display state (pseudo consecutive change) of decorative symbols. "Pseudo consecutive change" refers to a display mode in which, during a decorative symbol change display game, some or all of the decorative symbols are temporarily placed in 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 "prediction notice display (continuous notice display)" described below, which is developed across multiple symbol change display games. The occurrence rate (appearance rate) of such "pseudo consecutive displays" is basically set so that the more pseudo changes there are, the higher the chance of winning. For example, the number of pseudo changes makes it easier to select effects that create anticipation, such as a super reach.

"Prediction notice effect" (hereinafter sometimes abbreviated as "prediction notice" or "prediction effect") refers to an effect that notifies the player of the possibility of being controlled to an advantageous state before the display of the symbols to be judged is performed based on the results of the prediction judgment. "Advantageous state" refers to a state that is advantageous to the player.
Specifically, the pre-reading effect is performed for reserved balls (unconsumed reserved balls) that have not yet been used to execute the symbol variation display game (the operation of displaying the variation of special symbols), mainly by utilizing the reserved display mode and the background effect of the symbol variation display game that is executed first, in an effect mode that can notify the probability of winning in advance before the reserved balls are used to execute the symbol variation display game. In addition to the above-mentioned "reach effect," various effects such as so-called "SU (step-up) notice effect,""timer notice effect,""revivaleffect," and "premium notice effect" are generated in the symbol variation display game to liven up the game content.

Here, referring to Figure 5, we will explain the "hold change notice effect" as an example of the above-mentioned pre-reading notice effect.
In the gaming machine 1 of this embodiment, the upper display area of the screen of the main liquid crystal display device 20M is provided with a display area for displaying the decorative symbol change display game (a display area for displaying decorative symbol change display effects and preview effects), and the lower display area of the screen is provided with a reserved display area 60 (reserved display sections a1 to d1) that displays the number of reserved balls on the special symbol 1 side, and a reserved display area 61 (reserved display sections a2 to d2) that displays the number of reserved balls on the special symbol 2 side. The presence or absence of reserved balls is notified by a predetermined reserved display mode. FIG. 5 shows an example in which information regarding the current number of reserved balls is notified by indicating whether or not there are reserved balls with a lit state (reserved balls: "○ (white circle)" shown in the figure) or an unlit state (no reserved balls: dashed circle shown in the figure).

Displays indicating the presence or absence of reserved balls (reserved display) are displayed sequentially in the order of their occurrence (winning order). In each reserved display area 60, 61, the leftmost reserved ball is displayed as the reserved ball that occurred first on the timeline (i.e., the oldest) of all reserved balls in that reserved display. Also, to the left of the reserved display areas 60, 61, a changing display area 62 is provided to show the reserved balls currently being used in the special symbol change display game. In this embodiment, the changing display area 62 is configured so that an image of the game-in-progress reserved ball K icon currently being used in the game is displayed on top of the seat J icon. In other words, when the special symbol 1 or special symbol 2 change display begins, the icon (icon image) of the oldest reserved display section a1 or a2 displayed in the reserved display area 60, 61 moves to the seat J icon in the changing display area 62 as the game-in-progress reserved ball K icon, and this state is maintained for the specified display time.

When a reserved ball occurs, the main control board 40 sends to the performance control board 41 a "reserved addition command" that specifies the advance reading judgment information related to the jackpot lottery result and the number of reserved balls at the time of advance reading judgment (the number of currently existing reserved balls, including the reserved ball that has occurred 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 to be identified at the time of the pre-reading judgment, and data on the lower byte side that enables the pre-reading judgment information to be identified.

As can be understood from the above explanation, 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 created, a jackpot lottery is performed as a pre-reading judgment for the pattern change display game related to that reserved ball. The main control board 40 reserves and stores the pre-reading judgment information obtained by such pre-reading judgment in the corresponding memory area of RAM 40c.

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

When the effect control board 41 receives the above-mentioned hold addition command sent by the main control board 40, it performs effect control processing for the "pre-read preview effect" as part of the display control processing related to the above-mentioned hold display, based on the pre-read judgment information contained therein. Specifically, it performs a "pre-read preview lottery" to determine whether or not the pre-read preview effect can be executed, and if the lottery is won, the pre-read preview effect is displayed.

The "predicted fluctuation pattern" obtained by the predictive judgment when a 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 in the fluctuation display operation. For example, to explain the case where the fluctuation pattern at the start of fluctuation is a fluctuation pattern that specifies "Super Reach 1," in this case, the content specified by the predictive fluctuation pattern can be specified not as the type of reach performance itself, "Super Reach 1," but as the "Super Reach type," which is its essential element.

In this embodiment, if the advance notice lottery is won, a "hold display change" advance notice performance (also referred to as a "hold change notice") is performed in which the hold icon that is the subject of the advance notice among the hold icons in the hold display sections a1 to d1 and a2 to d2 is changed from the white of the normal hold display (normal hold display mode) to a hold display (special hold display mode) with a warning display of blue, green, red, or a danger pattern (or special colors or patterns such as rainbow colors).
5 shows an example in which the reserved ball in the hatched reserved display section b1 has changed to a special reserved display. Here, the display of the reserved icon in blue, green, red, and danger pattern indicates a higher probability of winning in that order, and the display of the reserved icon in danger pattern is a premium reserved icon that indicates an extremely high probability of winning a jackpot.

(Direction means)
Various effects in the gaming machine 1 are produced by the effect means provided in the gaming machine 1. These effect means may be any stimulus transmission means capable of producing effects by appealing to human senses, such as sight, hearing, or touch. Representative examples include light-generating means (light display device 16a: light effect means) such as decorative lamps 16 and LED devices, sound-generating devices (sound generating device 17a: sound effect means) such as speakers 17, effect display devices (display means) such as the main LCD display device 20M and the sub-LCD display device 20S, pressure devices that transmit contact pressure to the operator's body, wind pressure devices that apply wind pressure to the player's body, and movable gadgets that produce visual effects through their movement. Here, effect display devices, like image display devices, are visually appealing displays, but differ from image display devices in that they also include devices that do not rely on images (e.g., 7-segment displays). The term "image display device" primarily refers to a type that produces effects through image display; devices that produce effects through means other than images, such as 7-segment displays, are included within the concept of effect display devices.

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

One end of the transmission line H1 is connected to the power supply board 70, and the other end branches off and is connected to the payout control board 42 and the game ball lending device connection terminal board 71. The power supply board 70 supplies 35V DC (DC 35VA), 12V DC (DC 12VA), and 5V DC (DC 5VA) to the payout control board 42 via transmission line H1. The power supply board 70 also supplies AC input power (AC 24V) to the game ball lending device connection terminal board 71 via transmission line H1. The game ball lending device connection terminal board 71 is connected to the game ball lending device and sends and receives various signals to and from the game ball lending device.

The dispensing control board 42 is connected to the main control board 40 via a transmission line H2. The dispensing control board 42 generates a backup power supply (VBB) based on a 5V DC voltage (DC5VA) that is supplied to the RAM 40c and the RAM of the integrated circuit IC7 (see FIG. 9) when the power is turned off. 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) the 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.

The dispensing control board 42 generates a 5V DC voltage (DC5VH) based on a 12V DC voltage (DC12VA). The dispensing control board 42 is also connected to a relay board 72 via transmission line H3. The dispensing control board 42 supplies a 35V DC voltage (DC35VA), a 12V DC voltage (DC12VA), and a 5V DC voltage (DC5VH) to the relay board 72 via transmission line H3.

The power supply board 70 is also connected to the performance control board 41 via a transmission line H4, a power supply relay board 73, and a transmission line H5.

<5. Configuration of dispensing control board>
[5.1 Structure of the dispensing control board]
Figure 7 is a diagram showing the wiring pattern on the component side 42a of the dispensing control board 42. Figure 8 is a diagram showing the wiring pattern on the solder side 42b of the dispensing control board 42. Figure 9 is a diagram showing the layout of electronic components on the dispensing control board 42. Note that Figure 8 is a diagram that is flipped left to right to make it easier to understand the connection relationship with Figures 7 and 9.
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 with a ground pattern 42c as a solid ground formed on the component side 42a, which is the front surface, and a solder side 42b, which is the back surface, and with multiple conductive wiring patterns formed on them. As shown in Figures 10 and 11, the dispensing control board 42 has multiple 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 provided 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 conductive material, and includes through holes into which terminals of electronic components are inserted, and through-hole vias that electrically connect the wiring patterns on the component surface 42a and the solder surface 42b.

As shown in Figure 9, the dispensing control board 42 is equipped with multiple electronic components. All electronic devices are lead components, and the terminals (leads) of the electronic components arranged on the component surface 42a are inserted into through-holes and then soldered from the solder surface 42b, thereby fixing them to the dispensing control board 42 and electrically connecting them to the wiring patterns formed on the component surface 42a and 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 gaming board 5 so that it can be seen, making it possible to check (visually check) the electronic components mounted on the payout control board 42 while the payout control board 42 is attached to the gaming board 5.

Electronic components include connectors CN (CN1-CN7), integrated circuits IC (IC1-IC22), resistors R (R1-R97), capacitors C (C1-C79), noise reduction 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 ends of the transmission lines H3 (see FIG. 6) that connect the connectors CN2 and CN6 to 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 the 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.

[5.2 Input/output voltage of the dispensing control board]
12 is a diagram explaining the input/output voltages and supply destinations of the dispensing control board 42. As described above, the dispensing control board 42 is supplied with 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), and 5V DC voltage (DC5VA) from the power supply board 70.

As shown in Figure 12, the 35V DC voltage (DC35VA) supplied from the power supply board 70 has a maximum current capacity set to 2.5A, and is supplied primarily to the main control board 40 (first special electric role solenoid 29a, second special electric role solenoid 30a), the launch solenoid provided in the launch device 44, and the ball feed solenoid (not shown) that sends game balls to the launch device 44.

The 12V DC voltage (DC12VA) supplied from the power supply board 70 has a maximum current capacity set to 5.0A and is supplied primarily to the main control board 40 (normal electric device solenoid 25a, proximity switch, various function displays, magnetic sensor, vibration sensor, solenoid, etc.), payout motor 46c, and proximity switch. Note that a proximity switch is a sensor that detects the passage of a game ball, such as the first start port detection sensor 23a or the supply depletion detection sensor 46a.

The 5V DC voltage (DC5VA) supplied from the power supply board 70 has a maximum current capacity set to 2.5A and is primarily supplied to the main control board 40 (CPU 40a) and the integrated circuit IC7 provided on the dispensing control board 42, and is also used to generate control signals on the dispensing control board 42.

In addition, the payout control board 42 generates (in-house) a 5V DC voltage (DC5VH) based on the 12V DC voltage (DC12VA) supplied from the power supply board 70. The 5V DC voltage (DC5VH) has a maximum current capacity set to 1.0A, and is supplied primarily to a handle volume (not shown) provided on the launching device 44 that detects the amount of operation of the launching operation handle 15, and a touch sensor (not shown) that detects whether the player is touching the handle.

Therefore, the 5V DC voltage (DC5VA) supplied from the power supply board 70 and the 5V DC voltage (DC5VH) generated by the payout control board 42 are the same voltage, but have different maximum current capacities and supply destinations. In particular, the 5V DC voltage (DC5VA) supplied from the power supply board 70, which is a stable operating power source, is supplied to supply destinations directly related to game control, such as the CPU 40a and integrated circuit IC7. On the other hand, the 5V DC voltage (DC5VH) generated by the payout control board 42 is supplied to supply destinations not directly related to game control, such as the handle volume and touch sensor (supply destinations related to the launch of game balls).

In addition, the dispensing control board 42 generates (in-house) a backup power supply (VBB) based on the 5V DC voltage (DC5VA) supplied from the power supply board 70. The backup power supply (VBB) is mainly supplied to the main control board 40 (RAM 40c) and the RAM of the integrated circuit IC7.

In addition, the operating power supplies (output voltages) output from the dispensing control board 42 include 35V DC voltage (DC35VA), 12V DC voltage (DC12VA), 5V DC voltage (DC5VA), 5V DC voltage (DC5VH), and a backup power supply (VBB).

The 35V DC voltage (DC35VA) output from the payout control board 42 has a maximum current capacity set to 1.3A, and is primarily supplied to the main control board 40 (first special electric role solenoid 29a, second special electric role solenoid 30a).

The 12V DC voltage (DC12VA) output from the dispensing control board 42 has a maximum current capacity set to 3.0A, and is supplied primarily to the main control board 40 (normal electric device solenoid 25a, proximity switch, various function display units, magnetic sensor, vibration sensor, solenoid, etc.), dispensing motor 46c, frame control switch, and proximity switch.

The 5V DC voltage (power supply voltage: DC5VA generated by the power supply board 70) 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: DC5VH generated by the dispensing control board 42) has a maximum current capacity set to 1.0A and is supplied primarily 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).

The power supply abnormality signal, asynchronous serial signal, frame bottom open signal, frame top open signal, and RWM clear signal are input via integrated circuit IC2, which functions as a Schmitt trigger buffer.

As shown in Figure 15, integrated circuit IC7 has a 71-terminal configuration, numbered "1" through "71," from pin 1 to pin 71. Integrated circuit IC7 has a built-in CPU, RAM, and ROM, and the CPU operates using a 5V DC voltage (DC5VA) supplied via pins 8, 19, and 52, controlling each part of the payout control board 42, the launch device 44, and the game ball payout device 46.

In addition, the RAM is supplied with a backup power supply (VBB) via pin 20, and the stored data can be backed up (retained) by supplying the backup power supply (VBB) when the power is cut off.

[5.4 35V DC voltage supply wiring]
16 is a diagram of a combined wiring pattern for a 35V DC voltage (DC35VA). Figure 16 is a combined diagram of the wiring pattern provided on the component surface 42a shown in Figure 7, the wiring pattern provided on the solder surface 42b shown in Figure 8, and the supply wiring for a 35V DC voltage (DC35VA) from the third pin to the sixth pin (CN1_3 to CN1_6) of the connector CN1 to the fifteenth and seventeenth pins (CN3_15, CN3_17) of the connector CN3, among the electronic components arranged on the dispensing control board 42 shown in Figure 9.

As shown in Figures 7 to 9, 13, 14, and 16, the dispensing control board 42 receives a 35V DC voltage (DC35VA) from the power supply board 70 via the four third to sixth pins (CN1_3 to CN1_6) of the connector CN1.

The four third to sixth pins (CN1_3 to CN1_6) of connector CN1 are connected to one end of wiring pattern L35b_1 on solder surface 42b. One end of wiring pattern L35a_1 on component surface 42a is connected to the middle of wiring pattern L35b_1 via four through holes T35_1 to T35_4. One end of wiring pattern L35a_2 on solder surface 42b is connected to the other end of wiring pattern L35a_1 via four through holes T35_5 to T35_8. The fifteenth and seventeenth pins (CN3_15, CN_17) of connector CN3 are connected to the other end of wiring pattern L35b_2.

Therefore, the 35V DC voltage (DC35VA) input to the four third to sixth pins (CN1_3 to CN1_6) of connector CN1 is supplied to the fifteenth and seventeenth pins (CN3_15, CN_17) of connector CN3 through wiring patterns L35b_1, L35a_1, and L35b_2, and is output to the main control board 40 from the fifteenth and seventeenth pins (CN3_15, CN_17) of connector CN3.

The other end of wiring pattern L35b_1 is connected to integrated circuit IC22, and a 35V DC voltage (DC35VA) is supplied to integrated circuit IC22 via wiring pattern L35b_1. The 35V DC voltage (DC35VA) supplied to integrated circuit IC22 is used as the operating power source for the launch solenoid and ball-feed solenoid, and is therefore output to launch device 44 via connector CN6.

Furthermore, a signal is supplied to a power supply abnormality signal generating circuit via a noise removal filter FLT1 and the like midway along wiring pattern L35b_1. The power supply abnormality signal generating circuit is mainly composed of integrated circuit IC5, resistors R16 to R21, capacitors C20 to C26, and a portion of integrated circuit IC3. The power supply abnormality signal generating circuit monitors voltage drops in the 35V DC voltage (DC35VA) and a 12V DC voltage (DC12VA) described below, and when the voltage drops below a predetermined threshold, it outputs a power supply abnormality signal (ABNORMAL) to the main control board 40 via pins 3 and 5 of connector CN3 and inputs it to pin 70 of integrated circuit IC7.

[5.5 12V DC voltage supply wiring]
17 is a diagram of a combined wiring pattern for a 12V DC voltage (DC12VA). This diagram is 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 wiring for supplying 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.

As shown in Figures 7 to 9, 13, 14, and 17, the dispensing control board 42 receives a 12V DC voltage (DC12VA) from the power supply board 70 via the four pins 9 to 12 (CN1_9 to CN1_12) of connector CN1.

The four 9th to 12th pins (CN1_9 to CN1_12) of connector CN1 are connected to one end of wiring pattern L12b_1 on the solder side 42b. The other end of wiring pattern L12b_1 is connected to one end of wiring pattern L12a_1 on the component side 42a via nine through holes T12_1 to T12_9. Wiring pattern L12a_1 branches into wiring patterns L12a_2 and L12a_3, and the end of wiring pattern L12a_2 is connected to one end of wiring pattern L12b_2 on the solder side 42b via six through holes T12_10 to T12_15. The 9th and 11th pins (CN3_9, CN3_11) of connector CN3 are connected to the other end of 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 to the main control board 40 from the 9th and 11th pins (CN3_9, CN3_11) of connector CN3.

Meanwhile, the end of wiring pattern L12a_3 is connected to noise reduction filter FLT2, and the 12V DC voltage (DC12VA) that passes through noise reduction filter FLT2 is supplied to the power supply abnormality signal generation circuit, integrated circuits IC12-IC15 and IC18, pin 24 of connector CN2, and pins 4, 6, and 18 of connector CN6, etc.

In addition, integrated circuits IC12 and IC13 are circuits for controlling the display of 7-segment display FND1, and operate using the supplied 12V DC voltage (DC12VA) and 5V DC voltage (DC5VA) described below to display information on 7-segment display FND1. Note that 7-segment display FND1 can display performance information, similar to 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 that 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 reduction filter FLT9. As a result, the 5V DC voltage (DC5VH) is output to the game ball dispenser via the first pin (CN4_1) of the connector CN4 and the game ball dispenser 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 touch sensor.

[5.6 5V DC voltage supply wiring]
Figure 18 is a diagram of a combined wiring pattern for a 5V DC voltage (DC5VA). Figure 18 is a combined diagram of the wiring pattern provided on the component surface 42a shown in Figure 7, the wiring pattern provided on the solder surface 42b shown in Figure 8, and the supply wiring for a 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 Figure 9.

As shown in Figures 7 to 9, 13, 14, and 18, the dispensing control board 42 receives a 5V DC voltage (DC5VA) from the power supply board 70 via the four 15th to 18th pins (CN1_15 to CN1_18) of 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 wiring pattern L5b_2 is connected to noise reduction filter FLT3, and the 5V DC voltage (DC5VA) that passes through noise reduction filter FLT3 is supplied to the DC5VA monitoring circuit, backup power generation circuit 80, etc., and is also supplied as operating power to each part of dispensing control board 42 (for example, integrated circuits IC2, IC7 to IC11, IC17). 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 composite diagram of the wiring pattern of the backup power supply (VBB). Fig. 19 is a composite diagram of the wiring pattern provided on the component side 42a shown in Fig. 7, the wiring pattern provided on the solder side 42b shown in Fig. 8, and the backup power supply wiring from wiring pattern L5b_2 to the fourth pin and sixth pin (CN3_4, CN3_6) of 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, with the positive terminal (lead pin) connected to the middle of the wiring pattern LVb_1 and the negative terminal (lead pin) connected to ground. Therefore, when a 5V DC voltage (DC5VA) is supplied to the electrolytic capacitor C13, it stores charge as a backup power source (VBB), and when the supply of the 5V DC voltage (DC5VA) is stopped (when the power is turned off), it outputs the backup power source (VBB) to the wiring pattern LVb_1.

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

Furthermore, 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 extracted from 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 wiring pattern L5a_2 on component surface 42a is connected to the middle of wiring pattern L5b_3 via through hole T5_5, and the other end of wiring pattern L5a_2 is connected to the middle of wiring pattern L5b_4 on solder surface 42b via through hole T5_6.

One end of wiring pattern L5b_4 is connected to one end of wiring pattern L5a_3 on component side 42a via through hole T5_7, and one end of wiring pattern L5a_3 is connected to one end of wiring pattern L5b_5 on solder side 42b via through hole T5_8. The other end of wiring pattern L5b_5 is connected to one end of wiring pattern L5a_4 on component side 42a via through hole T5_9, and the other end of wiring pattern L5a_4 is connected to pin 52 of 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 pin 8 of integrated circuit IC7.

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

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

Meanwhile, one end of wiring pattern LVa_1 on component side 42a is connected to the other end of wiring pattern LVb_1 via through hole TB_1, and one end of wiring pattern LVb_3 on solder side 42b is connected to the other end of wiring pattern LVa_1 via through hole TB2. One end of wiring pattern LVb_4 is connected to the other end of wiring pattern LVb_3 via resistor R22. The other end of wiring pattern LVb_4 is connected to pin 20 of integrated circuit IC7. Therefore, backup power (VBB) is supplied to integrated circuit IC7 from pin 20.

The CPU of integrated circuit IC7 operates using 5V DC (DC5VA) supplied from pins 8, 19, and 52, and controls each part of the payout control board 42, the launcher 44, and the game ball payout device 46 by loading and executing a program stored in ROM into RAM. For example, the CPU instructs the launcher 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 down and no 5V DC voltage (DC5VA) is supplied, the CPU stops operating and the backup power supply (VBB) is supplied via pin 20. Then, 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)
The gaming machine 1 is a gaming machine having a circuit board, and the circuit board has 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 the 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 terminal in the output connector from which the backup power is output, and the second wiring pattern is configured to be shorter than the first wiring pattern.

In this (Configuration A1-1) concept, the board corresponds to the dispensing control board 42, the specified power supply step-down corresponds to 5V DC (DC5VA), the input connector corresponds to connector CN1, the backup power supply corresponds to the backup power supply (VBB), the output connector corresponds to connector CN3, and the terminals at the input connector to which the specified power supply voltage is input correspond to pins 15 to 18 (CN1_15 to CN1_18) of connector CN3. Furthermore, 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 pins 15 to 18 (CN1_15 to CN1_18) of connector CN1, it is input to two through holes T5_1 and T5_2 through wiring pattern L5b_1 on solder surface 42b. The 5V DC voltage (DC5VA) input to the two through holes T5_1 and T5_2 is guided to the component surface 42a side via through holes T5_1 and T5_2, and then input to two through holes T5_3 and T5_4 through wiring pattern L5a_1. The 5V DC voltage (DC5VA) input to the two through holes T5_3 and T5_4 is guided to the solder surface 42b side via through holes T5_3 and T5_4, and then input to noise reduction filter FLT3 through 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.

Meanwhile, as shown in FIG. 19, the backup power supply (VBB) is generated by the backup power supply generation circuit 80 based on a 5V DC voltage (DC5VA) and stored in the electrolytic capacitor C13. When a power outage occurs and the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13, 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 input to the noise reduction filter FLT4 is then output from the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 via the noise reduction filter FLT4 and the wiring pattern LVb_2 on the solder surface 42b to the main control board 40. 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 approximately 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 for 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 RAM 40c backup during a power outage can be improved.

Specifically, as shown in Figure 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 placing 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 (VBB) output to the main control board 40 passes, to be shorter on the dispensing control board 42. Thus, by shortening the wiring patterns LVb_1 and LVb_2 through which the backup power (VBB) output to the main control board 40 passes, the effects of noise can be reduced and the stability of the RAM 40c backup during a power outage can be improved.

Diode D5 is also positioned closer to connector CN1 than electrolytic capacitor C13. Diode D5 is also positioned so that its anode terminal is closer to connector CN1 than its cathode terminal. This allows the dispensing control board 42 to shorten the wiring pattern when connecting pins 15 to 18 (CN1_15 to CN1_18) of connector CN1 to diode D5, which constitutes backup power generation circuit 80, and reduces the impact of noise on the wiring pattern through which 5V DC voltage (DC5VA) passes.

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

In this (Configuration A1-2) approach, 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 a power outage occurs and 5V DC voltage is no longer supplied to the positive terminal of electrolytic capacitor C13, the backup power supply (VBB) is input from the positive terminal of electrolytic capacitor C13 to through-hole TB_1 through wiring pattern LVb_1 on solder surface 42b. The backup power supply (VBB) input to through-hole TB_1 is guided to component surface 42a via through-hole TB_1 and then input to resistor R22 through wiring pattern LVa_1. The backup power supply (VBB) input to resistor R22 is then input to pin 20 of integrated circuit IC7 through resistor R22 and 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 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, noise entering the backup power supply (VBB) output to the main control board 40 can be reduced, ensuring reliable backup of RAM 40c in the event of a power outage.

Specifically, as shown in Figure 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 and LVb_2, through which the backup power (VBB) output to the main control board 40 passes, to be shorter on the dispensing control board 42. By shortening the wiring patterns LVb_1 and LVb_2, through which the backup power (VBB) output to the main control board 40 passes, the effects of noise are reduced, and the stability of the backup of RAM 40c in the event of a power outage can be more reliably ensured.

In addition to (Configuration A1-1) and (Configuration A1-2), the gaming machine 1 of the embodiment also 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 this (Configuration A1-3) approach, the output connector, connector CN3, outputs 5V DC (DC5VA) and backup power (VBB) to the main control board 40. In other words, the 5V DC (DC5VA) input from the power supply board 70 is branched by wiring pattern L5b_2, with one branch being supplied directly to the 10th and 12th pins (CN3_10, CN3_12) of connector CN3 and output to the main control board 40, and the other branch being supplied to the backup power generation circuit 80, which generates backup power (see Figure 19).

In this 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. This allows the wiring pattern (L5b_2) after branching to be shorter, and also simplifies the wiring.

The gaming machine 1 of the embodiment has the following (Configuration A2-1).
(Configuration A2-1)
The 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 backup power based on the predetermined power supply voltage, a control circuit to which the backup power supply is input, a first wiring pattern that connects the 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 shorter than the first wiring pattern.

In this (Configuration A2-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply step-down corresponds to 5V DC voltage (DC5VA), the input connector corresponds to connector CN1, the backup power supply corresponds to the backup power supply (VBB), the backup power supply generation circuit corresponds to the backup power supply generation circuit 80, and the control circuit corresponds to the integrated circuit IC7. Furthermore, 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, LVa_1, LVb_3, and LVb_4.

As mentioned 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 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.

Furthermore, when a power outage occurs and 5V DC voltage is no longer supplied to the positive terminal of electrolytic capacitor C13, the backup power supply (VBB) is input from the positive terminal of electrolytic capacitor C13 to through-hole TB_1 through wiring pattern LVb_1 on solder surface 42b. The backup power supply (VBB) input to through-hole TB_1 is conducted to component surface 42a via through-hole TB_1, and then input to through-hole TB_2 through wiring pattern LVa_1. The backup power supply (VBB) input to through-hole TB_2 is conducted to solder surface 42b via through-hole TB_2, and then input to resistor R22 through wiring pattern LVb_3. The backup power supply (VBB) input to resistor R22 is input to pin 20 of integrated circuit IC7 via resistor R22 and 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 integrated circuit IC7 passes is shorter than the total length (approximately 290 mm) of the wiring pattern through which the 5V DC voltage (DC 5VA) input from power supply board 70 to backup power generation circuit 80 passes. In this way, by making the wiring pattern for the backup power supply (VBB) input to integrated circuit IC7 shorter than the wiring pattern through which the 5V DC voltage (DC 5VA) input from power supply board 70 to backup power generation circuit 80 passes, noise entering the backup power supply (VBB) is reduced, and the stability of the RAM backup of integrated circuit IC7 during a power outage can be improved.

Specifically, as shown in Figure 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, 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 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 is 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 on 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 RAM backup of the integrated circuit IC7 can be improved when the power is turned off.

Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A2-2) in addition to (Configuration A2-1).
(Configuration A2-2)
First and second power supply voltages having different voltages are input to the input connector, and the board generates a third power supply voltage having the same voltage as the first power supply voltage based on the second power supply voltage, and the backup power supply generation circuit generates a backup power supply based on the first power supply voltage.

In 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).

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

Therefore, stable control is achieved for components directly involved in game control by the 5V DC voltage (DC5VA) generated by the power supply board 70, and components not directly involved in game control are operated by the 5V DC voltage (DC5VH) generated by the payout control board 42. This reduces the impact on components directly involved in control by the operating voltage supplied to components not directly involved in game 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 having a circuit board, the circuit board having 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 the 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 this (Configuration A3-1) concept, the board corresponds to the dispensing control board 42, the predetermined power supply step-down corresponds to 5V DC voltage (DC5VA), the backup power supply corresponds to the backup power supply (VBB), the output connector corresponds to connector CN3, the backup power supply generation circuit corresponds to the backup power supply generation circuit 80, and the control circuit corresponds to the integrated circuit IC7. Furthermore, the first wiring pattern corresponds to wiring patterns LVb_1 and LVb_2, and the second wiring pattern corresponds to 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 interrupted.

Specifically, as shown in Figure 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 and LVb_2, through which the backup power supply (VBB) output to the main control board 40 passes, to be short on the dispensing control board 42. Thus, 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.

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

In this (Configuration A3-2) approach, 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 mentioned 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 Figure 9, connector CN1 is located in the upper right corner of the dispensing control board 42. The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is located closer to integrated circuit IC7 than connector CN1.

In this way, by arranging the backup power generation circuit 80 closer to the integrated circuit IC7 than the connector CN1, it is 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 on 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 RAM backup of the integrated circuit IC7 can be improved when the power is turned off.

Furthermore, the gaming machine 1 of the embodiment has the following (Configuration A3-3) in addition to (Configuration A3-1) and (Configuration A3-2).
(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 using an electrolytic capacitor C13 that can be charged and whose performance does not change, instead of electronic components such as batteries that may not be able to restore the original state if they deteriorate, as the electronic component that generates the backup power supply (VBB), the stability of the RAM backup of RAM 40c and integrated circuit IC7, which affect game play and ball output, can be further improved.

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

This simple configuration makes it possible 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 supply of the backup power supply (VBB) from reducing the backup time of the RAM 40c and the RAM of the integrated circuit IC7.

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

Here, as shown in FIG. 9, diode D5 is positioned so that its cathode terminal is closer to the positive terminal of electrolytic capacitor C13 than its anode terminal. Furthermore, electrolytic capacitor C13 is positioned 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 positioned 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.

This allows the wiring pattern on the dispensing control board 42 to be shortened when connecting the electrolytic capacitor C13 and diode D5 that make up the backup power generation circuit 80, 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, and the circuit board is supplied with a predetermined power supply voltage and is equipped with a plurality of power lines with different maximum current capacities, and one or more through holes that connect the power lines formed on different layers of the circuit board, and the power line with a larger maximum current capacity is configured to be connected to a larger number of through holes than the power line with a smaller maximum current capacity.

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

Figure 21 is a diagram illustrating 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 12V DC voltage (DC12VA), have a line width (hereinafter simply referred to as width) of 5mm, and are set to a maximum current capacity of 5.0A. Furthermore, wiring patterns L12b_1 and L12a_1 are connected via nine through holes (T12_1 to T12_9), each with a diameter of 0.5mm.

In addition, wiring patterns L12a_2 and L12b_2 are supplied with a 12V DC voltage (DC12VA), are 3mm wide, and have a maximum current capacity of 3.0A. Furthermore, wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), each with a diameter of 0.5mm.

In addition, wiring patterns L35a_1 and L35b_2 are supplied with a direct current voltage of 35V (DC35VA), are 2mm wide, and have a maximum current capacity of 1.3A. Furthermore, wiring patterns L35a_1 and L35b_2 are connected via two through holes (T35_1-T35_2), each with a diameter of 0.5mm.

Therefore, a combination of wiring patterns with a larger maximum current capacity will have 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 amount can be reduced, and heat generation can be suppressed.

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

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

In this way, even if the supplied power supply voltages are different, the larger the maximum current capacity of a combination of wiring patterns, the more through holes are connected, 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.

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

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

The gaming machine 1 of the embodiment has the following (Configuration B2-1).
(Configuration B2-1)
The gaming machine 1 is a gaming machine that includes a circuit board, and the circuit board includes one or more power lines that are supplied with a predetermined power supply voltage and have different maximum current capacities, and a plurality of through holes that connect the power supply lines formed on different layers of the circuit board, and the power supply lines that have the same power supply voltage but different maximum current capacities are configured to be connected to different numbers of through holes.

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

Figure 22 is a diagram illustrating the relationship between the maximum current capacity of the power supply voltage and the number of through holes. As shown in Figure 22, wiring patterns L12b_1 and L12a_1 are supplied with a 12V DC voltage (DC12VA), are 5mm wide, 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), each with a diameter of 0.5mm.

Wiring patterns L12a_2 and L12b_2 are supplied with a 12V DC voltage (DC12VA), are 3mm wide, and have a maximum current capacity of 3.0A. Furthermore, wiring patterns L12a_2 and L12b_2 are connected via six through holes (T12_10 to T12_15), each with a diameter of 0.5mm.

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 the combination of wiring patterns is supplied with the same power supply voltage, if the maximum current capacity is different, the number of connected through holes can be varied to reduce the electrical resistance in the through holes when current flows through a wiring pattern with a large current amount, thereby suppressing heat generation.

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

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

In this way, even if the power supply voltage is the same, the wider the wiring pattern width is, the larger the maximum current capacity of the combination of wiring patterns is, thereby reducing the electrical resistance when 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)
The gaming machine 1 is a gaming machine that includes a circuit board, and the circuit board includes a power line to which a predetermined power supply voltage is supplied and one or more through holes that connect the power lines formed on different layers of the circuit board, and the power line may branch into multiple lines, with the number of through holes connected to the power line before branching being greater than the number of through holes connected to the power line after branching.

In this (Configuration B3-1) approach, the board corresponds to the dispensing control board 42. Furthermore, the power lines before branching and the through holes connecting those power lines correspond to the combination of wiring pattern L12a_1 and through holes T12_1 to T12_9. Furthermore, the power lines after branching and the through holes connecting those 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 Figure 22, the wiring pattern L12a_1 before branching is supplied with a 12V DC voltage (DC12VA), is 5mm wide, and has a maximum current capacity of 5.0A. Furthermore, the wiring pattern L12a_1 before branching is connected via nine through holes (T12_1 to T12_9), each with a diameter of 0.5mm.

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

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

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 can be reduced when current flows through a wiring pattern with a large current amount, thereby suppressing heat generation.

Furthermore, the gaming machine 1 of the embodiment has the following (Configuration B3-2) in addition to (Configuration B3-1).
(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 branching is wider than the width (3 mm) of the power supply line after branching. By making the width of the wiring pattern L12a_1 before branching wider than the width of the power supply line after branching, electrical resistance can be reduced when a current flows through a wiring pattern with a large current amount, and heat generation can be suppressed.

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

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

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

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

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

This means that when there are a small number of through holes to be connected and there is a risk that a large amount of current will flow 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)
The gaming machine 1 is a gaming machine that includes a circuit board, and the circuit board is supplied with a predetermined power supply voltage and includes one or more power lines with different maximum current capacities, and a plurality of through holes that connect the power lines formed on different layers of the circuit board, and the through holes are connected so that the product of the diameter and number of the through holes is larger for power lines with larger maximum current capacities than for power lines with smaller maximum current capacities.

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

Figure 24 is a diagram illustrating 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 12V DC voltage (DC12VA), are 5mm wide, 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), each with a diameter of 0.5mm. Therefore, in this case, the product of the diameter and number of through holes is 4.5.

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

Wiring patterns L5b_1 and L5a_1 are supplied with a 5V DC voltage (DC5VA), are 3mm wide, and have a maximum current capacity of 2.5A. Furthermore, wiring patterns L5b_1 and L5a_1 are connected via two through holes (T5_1-T5_2), each with a diameter of 0.8mm. Therefore, in this case, the product of the diameter and 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 with 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 multiple power lines with different maximum current capacities, and one or more vias that connect the power lines formed on different layers of the substrate, and is configured so that the number of vias connected by the power lines varies.

In this (configuration C1-1) approach, the board corresponds to the dispensing control board 42. Furthermore, the power supply lines and the through holes connecting those power supply lines correspond to the combination of wiring patterns L12b_1, L12a_1 and through holes T12_1 to T12_9, the combination of wiring patterns L12a_2, L12b_2 and through holes T12_10 to T12_15, and the combination of wiring patterns L35a_1, L35b_2 and 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 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) above can be combined in various ways, and by combining them arbitrarily, a gaming machine 1 can be created that combines the effects described for each configuration.
In addition, it is possible to combine the configurations and operations described in the embodiments.
Furthermore, the various specific examples given are merely one way of realizing each configuration, and various specific examples that are not specifically shown are also possible.
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 slot machine, the board configuration, circuit configuration, connector configuration, power supply configuration, etc., as explained in each embodiment can also be adopted.

The present invention can also be applied to a controlled gaming machine in which gaming balls circulate within the gaming machine 1. In the case of a controlled gaming machine, there is no need to supply AC input power (24V AC) to the gaming ball dispensing device connection terminal board 71. There is no need to branch the transmission line H1 as shown in Figure 6. However, if the power supply board 70 is also changed to no longer supply AC input power (24V AC) to the gaming ball dispensing device connection terminal board 71, it will be necessary to redesign the power supply board 70, and the existing power supply board 70 cannot be reused.

In this managed gaming machine, as shown in Figures 25 to 28, AC input power (24V AC) is input from pins 25 and 26 of connector CN1 on payout control board 42, and LED1 is illuminated via bridge circuit DB1 and resistor R1. This makes it 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 existing power supply board 70.

Furthermore, 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.

Furthermore, 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 the payout control board 42 to the main control board 40. However, the 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 the performance control board 41 or the launch control board 45.
