Description

[Technical field]

[0001] The present invention relates to a gaming machine capable of playing a game. [Background technology]

[0002] Some conventional gaming machines have a power supply board (electronic circuit board) that provides power to electrical components within the gaming machine, and has conductor wiring patterns (conductor wiring patterns) formed on both the front (first surface) and back (second surface) of the power supply board (electronic circuit board) (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-117697 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the wiring pattern formed on the front side of the power supply board and the wiring pattern formed on the back side are separated only by the thickness of the power supply board, which causes a problem that each wiring pattern is easily affected by noise.

[0005] The present invention has been made in consideration of such problems, and has an object to provide a gaming machine that can reduce the effect of noise on conductor wiring patterns. [Means for solving the problem]

[0006] The gaming machine of claim 1 comprises: A gaming machine capable of playing games, a flat-plate-shaped electronic circuit board having a first surface and a second surface opposite to the first surface, on which electronic components can be mounted; the first surface has a first conductor wiring pattern that is a wiring pattern formed by a conductor and includes a specific wiring pattern having a first mounting electrode to which a first terminal of an electronic component to be mounted is electrically connected and a second mounting electrode to which a second terminal of the electronic component is electrically connected; a region between the first mounting electrode and the second mounting electrode on the first surface is a non-conductor region in which a conductor of the first conductor wiring pattern is not formed, the second surface has a second conductor wiring pattern including a special wiring pattern formed by a conductor on a back surface of the non-conductor region; The special wiring pattern is electrically connected to an overvoltage protection circuit. It is characterized by the following. According to this feature, since a special wiring pattern is formed on the opposite side of the non-conductive area across which electronic components are mounted, the distance between the special wiring patterns can be made greater than the thickness of the board, thereby reducing the influence of noise on the special wiring pattern or special wiring pattern from the special wiring pattern or special wiring pattern on the opposite side.

[0007] Furthermore, the present invention may have only the invention-specific matters described in the claims of the present invention, or may have the invention-specific matters described in the claims of the present invention as well as configurations other than the invention-specific matters.

[0036] A mode for carrying out the pachinko gaming machine 1 of the present invention will be described below based on an embodiment.

[0037] (Configuration of Pachinko Machine 1, etc.) Fig. 1 is a front view of a pachinko gaming machine 1, showing the layout of the main components. The pachinko gaming machine (gaming machine) 1 is broadly composed of a gaming board (gauge board) 2 that constitutes the gaming board surface, and a gaming machine frame (base frame) 3 that supports and fixes the gaming board 2. A gaming area is formed on the gaming board 2, and gaming balls as gaming media are shot into this gaming area by a predetermined ball shooting device.

[0038] In addition, the "variable display" of the special symbol means, for example, displaying multiple types of special symbols in a variable manner (the same applies to other symbols described later). The variations include updating the display of multiple symbols, scrolling the display of multiple symbols, transforming one or more symbols, and enlarging / reducing one or more symbols. In the variation of the special symbol or the normal symbol described later, multiple types of special symbols or normal symbols are updated and displayed. In the variation of the decorative symbol described later, multiple types of decorative symbols are scrolled or updated, or one or more decorative symbols are transformed or enlarged / reduced. In addition, the variation also includes a mode in which a certain symbol is displayed in a flashing manner. At the end of the variable display, a predetermined special symbol is displayed stationarily (also called derived or derived display) as a display result (the same applies to the variable display of other symbols described later). In addition, the variable display may be expressed as a variable display or a variation.

[0039] In addition, the special pattern variably displayed on the first special pattern display device 4A is also called the "first special pattern", and the special pattern variably displayed on the second special pattern display device 4B is also called the "second special pattern". In addition, a special pattern game using the first special pattern is also called the "first special pattern game", and a special pattern game using the second special pattern is also called the "second special pattern game". In addition, there may be only one type of special pattern display device that variably displays the special pattern.

[0040] An image display device 5 is provided near the center of the play area on the game board 2. The image display device 5 is composed of, for example, an LCD (liquid crystal display device) or an organic EL (electro luminescence) display, and displays various effect images. The image display device 5 may be composed of a projector and a screen. The image display device 5 displays various effect images.

[0041] For example, on the screen of the image display device 5, in synchronization with the first special game or the second special game, a plurality of types of decorative patterns (such as patterns showing numbers, etc.) different from the special pattern are variably displayed as decorative identification information. Here, in synchronization with the first special game or the second special game, decorative patterns are variably displayed (for example, scrolled up and down or updated) in each of the "left", "center", and "right" decorative pattern display areas 5L, 5C, and 5R. The special game and the variable display of decorative patterns executed in synchronization are collectively referred to simply as variable display.

[0042] In addition, a display area 5S is provided in the upper left corner of the display screen (display area) of the image display device 5 for displaying a first reserved memory number (for example, the number "0"), a second reserved memory number (for example, the number "4") and a small pattern corresponding to the decorative pattern, and the small pattern is variably displayed in response to the variable display of the decorative pattern.

[0043] In addition, the first reserved memory number, the second reserved memory number, the reserved display, the small pattern, the error display (not shown) indicating an error state that has occurred in the pachinko game machine 1, the right-hit notification image that encourages the player to perform a right-hit operation, and the remaining time-saving display that shows the number of remaining times of time-saving are displayed in front of (in a higher layer) the performance images (object images) such as characters, thereby preventing the performance images from overlapping and reducing the visibility of the first reserved memory number, the second reserved memory number, the small pattern, and the error display, while the decorative patterns may be displayed behind (in a lower layer) the performance images, thereby preventing the decorative patterns from overlapping and reducing the visibility of the performance images.

[0044] The small symbol is also called the fourth symbol. The fourth symbol is displayed variably by a certain operation in a manner that is always visible on a display device such as the image display device 5 as a symbol indicating that the special symbols (first special symbol, second special symbol) are variably displayed. By variably displaying the fourth symbol, it becomes possible to recognize whether or not the decorative symbol is currently being variably displayed even if the decorative symbol is difficult to recognize, such as when a performance content including the variable display of the decorative symbol disappears from the screen for a moment, or when a performance is performed in which the movable body 32 covers all or part of the screen of the image display device 5. The performance control CPU 120 performs the variably display of the fourth symbol corresponding to the first special symbol by operating the image display device 5 based on receiving the first variable display start command. Also, the performance control CPU 120 performs the variably display of the fourth symbol corresponding to the second special symbol by operating the image display device 5 based on receiving the second variable display start command.

[0045] The lower part of the screen of the image display device 5 is provided with display areas (special symbol reserved memory display area 5U, active display area 5F) for displaying reserved displays corresponding to variable displays whose execution is reserved and active displays corresponding to variable displays that are being executed. The reserved displays and active displays are also collectively referred to as variable display-compatible displays corresponding to variable displays. In this embodiment, a special symbol reserved memory display area 5U common to the first special symbol and the second special symbol is provided, but a first special symbol reserved memory display area in which a first reserved display representing a variable display whose execution of the first special symbol is reserved is displayed, and a second special symbol reserved memory display area in which a second reserved display representing a variable display whose execution of the second special symbol is reserved may be provided separately. In this embodiment, the special symbol reserved memory display area 5U is a display area that displays a reserved display corresponding to the first special symbol when the game state is in a normal state, and is a display area that displays a reserved display corresponding to the second special symbol when the game state is in a time-saving state or a probability-changing state. Furthermore, the active display area 5F is a display area which displays an active display corresponding to a first special pattern when the game state is in a normal state, and is a display area which displays an active display corresponding to a second special pattern when the game state is in a time-saving state or a special probability state.

[0046] A first hold indicator 25A and a second hold indicator 25B, each of which includes a plurality of LEDs, are provided at predetermined positions on the game board 2. The first hold indicator 25A displays the first hold memory number by the number of lit LEDs. The second hold indicator 25B displays the second hold memory number by the number of lit LEDs.

[0047] A winning ball device 6A is provided below the image display device 5, and a variable winning ball device 6B is provided to the right of the winning ball device 6A.

[0048] The winning ball device 6A forms a first start winning hole that is always kept in a constant open state so that a game ball can enter, for example, by a predetermined ball receiving member. When a game ball enters the first start winning hole, a predetermined number of prize balls (for example, three balls) are paid out and a first special game can be started.

[0049] The variable winning ball device 6B (normal electric device) forms a second start winning hole that changes between a closed state and an open state by a solenoid 81 (see FIG. 2). The variable winning ball device 6B is, for example, an electric device having a movable piece that can be opened and closed, and when the solenoid 81 is in the off state, the movable piece is in the upright position, so that the second start winning hole is in a closed state in which the game ball does not enter (also referred to as the second start winning hole being in a closed state). On the other hand, when the solenoid 81 is in the on state, the movable piece of the variable winning ball device 6B is in a tilted position, so that the second start winning hole is in an open state in which the game ball can enter (also referred to as the second start winning hole being in an open state). When a game ball enters the second start winning hole, a predetermined number of prize balls (for example, three) are paid out and the second special game can be started. It should be noted that the variable winning ball device 6B is not limited to the above, as long as it can be changed between a closed state and an open state.

[0050] At predetermined positions on the game board 2 (in the example shown in FIG. 1, three positions at the lower left of the game area and one position above the variable winning ball device 6B), general winning openings 10 that are always kept in a constant open state by a predetermined ball receiving member are provided. In this case, when a ball enters one of the general winning openings 10, a predetermined number of game balls (for example, 10 balls) are paid out as prize balls.

[0051] Between the winning ball device 6A and the variable winning ball device 6B, a first special variable winning ball device 7A and a second special variable winning ball device 7B each having a large winning opening are provided. The first special variable winning ball device 7A has a large winning opening door driven to open and close by a solenoid 82 (see FIG. 2), and forms a first large winning opening as a specific area that changes between an open state and a closed state by the large winning opening door, and the second special variable winning ball device 7B has a large winning opening door driven to open and close by a solenoid 83 (see FIG. 2), and forms a second large winning opening as a specific area that changes between an open state and a closed state by the large winning opening door.

[0052] In the first special variable winning ball device 7A, when the solenoid 82 for the large prize opening door (for the special electric device) is in the OFF state, the large prize opening door closes the first large prize opening, and the game ball cannot enter (pass through) the first large prize opening. On the other hand, in the first special variable winning ball device 7A, when the solenoid 82 for the large prize opening door is in the ON state, the large prize opening door opens the first large prize opening, and the game ball can easily enter the first large prize opening.

[0053] Similarly, in the second special variable winning ball device 7B, when the solenoid 83 for the large prize opening door (for the special electric device) is in the OFF state, the large prize opening door closes the second large prize opening, and the game ball cannot enter (pass through) the second large prize opening. On the other hand, in the second special variable winning ball device 7B, when the solenoid 83 for the large prize opening door is in the ON state, the large prize opening door opens the second large prize opening, and the game ball can easily enter the second large prize opening.

[0054] A gaming ball that enters the first large prize opening is detected by a first count switch 23 (see FIG. 2), and a gaming ball that enters the second large prize opening is detected by a second count switch 24 (see FIG. 2). When a gaming ball is detected by the first count switch 23 or the second count switch 24, that is, when a gaming ball enters the large prize opening, a predetermined number of gaming balls (for example, 15 balls) are paid out as prize balls. When a gaming ball enters the large prize opening, more prize balls are paid out than when a gaming ball enters the first start prize opening, the second start prize opening, or the general prize opening 10, for example.

[0055] The entry of a game ball into each winning port including the general winning port 10 is also called a "winning". In particular, the winning into the start port (first start winning port, second start winning port) is also called a start winning.

[0056] A normal symbol display 20 is provided at a predetermined position on the game board 2 (the lower left of the game area in the example shown in FIG. 1). As an example, the normal symbol display 20 is made up of a 7-segment LED or the like, and performs variable display of normal symbols as multiple types of normal identification information different from special symbols. The normal symbols are represented by numbers indicating "0" to "9" or lighting patterns such as "-". The normal symbols may include a pattern in which all LEDs are turned off. Such variable display of normal symbols is also called a normal symbol game.

[0057] A passing gate 41 through which the gaming ball can pass is provided to the right of the image display device 5. When the gaming ball passes through the passing gate 41, a regular game is executed.

[0058] A regular symbol reserved display 25C is provided below the regular symbol display 20. The regular symbol reserved display 25C is configured to include, for example, four LEDs, and displays the regular symbol reserved memory number, which is the number of regular symbol games that are reserved for execution, by the number of lit LEDs.

The main lamp 9a, side lamp 9b, attacca lamp 9c, movable body lamp 9d, button lamp 9e, and decorative lamp 9f are configured to include LEDs. The various lamps will be described later.

[0064] At the lower right position of the game machine frame 3, there is provided a ball-hitting operation handle (operation knob) 30 that is operated by a player or the like to launch a game ball toward the game area by the ball-hitting device.

[0065] At a predetermined position of the gaming machine frame 3 below the game area, a ball supply tray (upper tray) is provided to hold (store) gaming balls dispensed as prize balls or game balls lent by a predetermined ball lending machine so that they can be supplied to the ball launching device. In addition to the upper tray, the gaming machine frame 3 may be provided with a payout section (ball supply tray) from which prize balls are paid out when the upper tray is full.

[0066] A stick controller 31A that can be held and tilted by a player is attached to a predetermined position of the gaming machine frame 3 below the playing area. The stick controller 31A is provided with a trigger button that can be pressed by a player. The operation of the stick controller 31A is detected by a controller sensor unit 35A (see FIG. 2).

[0067] A push button 31B that allows a player to perform a predetermined instruction operation by pressing it or the like is provided at a predetermined position of the gaming machine frame 3 below the gaming area. The operation of the push button 31B is detected by a push sensor 35B (see FIG. 2).

[0068] In the pachinko gaming machine 1, the stick controller 31A and the push button 31B are provided as detection means for detecting the actions (operations, etc.) of the player, but detection means other than these may also be provided.

[0069] (Outline of game progress) The game ball is launched toward the game area by the player rotating the ball hitting operation handle 30 provided on the pachinko game machine 1. When the game ball passes through the passing gate 41, a normal game is started by the normal symbol display 20. If the game ball passes through the passing gate 41 during the period during which the previous normal game is being played (if the game ball passes through the passing gate 41 but the normal game based on the passing cannot be played immediately), the normal game based on the passing is put on hold up to a predetermined upper limit number (for example, 4).

[0070] In this normal game, if a specific normal symbol (normal winning symbol) is displayed, the display result of the normal symbol will be "normal winning". On the other hand, if a normal symbol other than the normal winning symbol (normal losing symbol) is displayed as the confirmed normal symbol, the display result of the normal symbol will be "normal losing". When it becomes "normal winning", an opening control is performed to keep the variable winning ball device 6B in an open state for a predetermined period of time (the second start winning port is opened).

[0071] When a game ball enters a first start winning hole formed in the winning ball device 6A, a first special symbol game is started by the first special symbol display device 4A.

[0072] When a gaming ball enters a second start winning hole formed in the variable winning ball device 6B, a second special symbol game is started by the second special symbol display device 4B.

[0073] Furthermore, if the game ball enters (wins) the start winning hole during the period when the special game is being played or during the period when the game is controlled to the jackpot game state described below (if a start winning occurs but the special game based on the start winning cannot be played immediately), the execution of the special game based on that entry will be put on hold up to a specified upper limit number (for example, 4).

[0074] In special symbol games, if a specific special symbol (a jackpot symbol, for example, "7"; the actual symbol varies depending on the type of jackpot described below) is displayed as a confirmed special symbol, it is a "jackpot", and if a special symbol other than the jackpot symbol (a losing symbol, for example, "-") is displayed as a confirmed special symbol, it is a "miss".

[0075] After the display result in the special game becomes "jackpot," the game is controlled to a jackpot game state, which is an advantageous state for the player.

[0076] In the jackpot game state, the first and second large prize openings formed by the special variable prize ball device 7 are opened in a predetermined manner. The open state continues until either a predetermined period (for example, 29 seconds or 1.8 seconds) has elapsed or the number of game balls entering the large prize openings reaches a predetermined number (for example, 9), whichever comes first. The predetermined period is the upper limit period during which the large prize openings can be opened in one round, and is hereinafter also referred to as the upper limit period of opening. A cycle in which the large prize openings are opened in this way is called a round (round game). In the jackpot game state, the round can be repeated until it reaches a predetermined upper limit number of times (10 times, 6 times, etc.).

[0077] In the jackpot game state, the player can get prize balls by making the game ball enter the big prize hole. Therefore, the jackpot game state is advantageous to the player. The more rounds in the jackpot game state, and the longer the upper limit period, the more advantageous it is for the player.

[0078] In addition, a jackpot type is set for a "jackpot". For example, a plurality of types of opening modes of the jackpot entrance (number of rounds or maximum opening period) and game states after the jackpot game state (normal state, time-saving state, probability change state, etc.) are prepared, and the jackpot type is set according to these. As the jackpot type, a jackpot type in which many prize balls can be obtained, a jackpot type in which few prize balls can be obtained, or a jackpot type in which almost no prize balls can be obtained may be provided.

[0079] After the jackpot game state ends, the game may be controlled to a time-saving state or a special state depending on the type of jackpot.

[0080] In the time-saving state, control (time-saving control) is executed to shorten the average special symbol fluctuation time (period during which the special symbol fluctuates) more than in the normal state. In the time-saving state, control (high opening control, high base control) is also executed to make it easier for the game ball to enter the second start winning hole by shortening the average regular symbol fluctuation time (period during which the regular symbol fluctuates) more than in the normal state and by improving the probability of a "regular symbol hit" in the regular symbol game more than in the normal state. The time-saving state is an advantageous state for the player because it is a state in which the fluctuation efficiency of the special symbols (especially the second special symbol) is improved.

[0081] In the probability variable state (probability variable state), in addition to time-saving control, probability variable control is executed to make the probability of the display result being a "jackpot" higher than in the normal state. The probability variable state is an even more advantageous state for the player, since it is a state in which the fluctuation efficiency of special symbols is improved and it is easier to get a "jackpot".

[0082] The time-saving state or the probability of winning state continues until one of the end conditions is met first, such as the execution of a specified number of special games or the start of the next big win game state. The end condition of the state in which a specified number of special games have been executed is also called the number-cut (number-cut time-saving, number-cut probability of winning, etc.).

[0083] The normal state refers to a game state other than advantageous states such as a jackpot game state that is advantageous to the player, and special states such as a time-saving state and a special probability state, and is a state in which the pachinko game machine 1, such as the probability that the display result in the normal game will be a "normal hit" and the probability that the display result in the special game will be a "jackpot", is controlled in the same way as the initial setting state of the pachinko game machine 1 (for example, when a system reset is performed and the specified return process is not executed after the power is turned on).

[0084] The state in which the probability variable control is being executed is also called the high probability state, and the state in which the probability variable control is not being executed is also called the low probability state. The state in which the time-saving control is being executed is also called the high base state, and the state in which the time-saving control is not being executed is also called the low base state. Combining these, the time-saving state is also called the low probability high base state, the probability variable state is the high probability high base state, and the normal state is the low probability low base state. The high probability state and the low base state are also called the high probability low base state.

[0085] In this embodiment, the large prize opening that opens in a specific round (for example, the sixth round) differs depending on the type of jackpot, and in the case of a jackpot type in which the second prize opening opens in the specific round, the game ball enters the second large prize opening, that is, based on the detection by the second count switch 24, the game state is controlled to a high probability high base state after the jackpot game ends.

[0086] (Progress of the performance, etc.) In the pachinko game machine 1, various effects (effects to notify the progress of the game or to liven up the game) are executed according to the progress of the game. The effects are described below. The effects are performed by displaying various effect images on the image display device 5, but in addition to or instead of the display, the effects may be performed as sound output from the speakers 8L and 8R, turning on or off the game effect lamp 9, operating the movable body 32, or using any effect device including some or all of these.

[0087] As an effect executed according to the progress of the game, in response to the start of the first special symbol game or the second special symbol game, the variable display of the decorative symbols is started in the "left", "center" and "right" decorative symbol display areas 5L, 5C and 5R provided in the image display device 5. At the timing when the display result (also called the determined special symbol) in the first special symbol game or the second special symbol game is stopped and displayed, the determined decorative symbol (combination of three decorative symbols) which is the display result of the variable display of the decorative symbols is also stopped and displayed (derived).

[0088] During the period from when the variable display of the decorative symbols starts to when it ends, the state of the variable display of the decorative symbols may become a predetermined reach state (a reach is achieved). Here, the reach state refers to a state in which the decorative symbols that have not yet been stopped and displayed on the screen of the image display device 5 continue to be variable displayed when the decorative symbols that have been stopped and displayed form part of a jackpot combination described later.

[0089] In addition, when the reach state is reached during the variable display of the decorative symbols, a reach effect is executed. In the pachinko game machine 1, a plurality of types of reach effects are executed, each of which has a different probability (also called the probability of a big win or the probability of a big win) of the display result (the display result of the special game or the display result of the variable display of the decorative symbols) becoming a "big win" according to the performance mode. The reach effects include, for example, a normal reach and a super reach, which has a higher probability of a big win than a normal reach.

[0090] When the display result of the special game is a "jackpot," a fixed decorative pattern that is a predetermined jackpot combination is derived as a display result of the variable display of decorative patterns on the screen of the image display device 5 (the display result of the variable display of decorative patterns is a "jackpot"). As an example, the same decorative patterns (for example, "7") are displayed stopped on a predetermined effective line in the "left," "center," and "right" decorative pattern display areas 5L, 5C, and 5R.

[0091] When the display result of the special game is a "miss," the state of the variable display of the decorative pattern does not become a reach state, and a fixed decorative pattern of a non-reach combination (also called a "non-reach miss") may be displayed as a static result of the variable display of the decorative pattern (the display result of the variable display of the decorative pattern becomes a "non-reach miss"). Also, when the display result is a "miss," after the state of the variable display of the decorative pattern becomes a reach state, a fixed decorative pattern of a predetermined reach combination (also called a "reach miss") that is not a jackpot combination may be displayed as a static result of the variable display of the decorative pattern (the display result of the variable display of the decorative pattern becomes a "reach miss").

[0092] The effects that the pachinko game machine 1 can execute include displaying the variable display compatible display (reserved display or active display). In addition, as other effects, for example, a preview effect that predicts the jackpot reliability is executed during the variable display of the decorative pattern. The preview effects include a preview effect that predicts the jackpot reliability in the variable display being executed, and a pre-reading preview effect that predicts the jackpot reliability in the variable display before execution (variable display whose execution is reserved). As a pre-reading preview effect, an effect that changes the display mode of the variable display compatible display (reserved display or active display) to a mode different from the normal mode may be executed.

[0093] In addition, in the image display device 5, a pseudo consecutive performance may be executed in which a single variable display appears to be multiple variable displays by temporarily stopping the decorative pattern during the variable display and then resuming the variable display.

[0094] During the jackpot game state, a jackpot game performance is executed to notify the player of the jackpot game state. As the jackpot game performance, a performance to notify the player of the number of rounds or a promotion performance to show that the value of the jackpot game state is increasing may be executed.

[0095] Also, for example, when a special game or the like is not being executed, a demo (demonstration) image is displayed on the image display device 5 (a customer waiting demo performance is executed).

[0096] (Board configuration 1) The pachinko gaming machine 1 is equipped with a game control board 11, a performance control board 12, a sound control board 13, a lamp control board 14, a relay board 15, and the like, as shown in Fig. 2. In addition, various boards, such as a payout control board, an information terminal board, and a launch control board, are arranged on the back of the pachinko gaming machine 1. Furthermore, a power supply board 17 is also equipped. The various control boards are not only electronic circuit boards such as printed wiring boards on which conductor patterns are formed and on which electrical components can be mounted, but also electronic circuit mounting boards configured to realize specific electrical functions by mounting electrical components on electronic circuit boards.

[0097] A power switch 91 is connected to the power supply board 17, and by operating the power supply switch 91 (turning it ON), power from an AC power source such as an external power source of AC 100V, such as a commercial power source, can be supplied from the power supply board 17 to electrical components including various control boards such as the game control board 11 and the performance control board 12. The power supply board 17 includes, for example, a rectifier circuit for converting alternating current (AC) to direct current (DC), and a power supply circuit for converting a predetermined DC voltage to a specific DC voltage (for example, DC 12V or DC 5V).

[0098] The game control board 11 is the main control board, and has the function of controlling the progress of the above-mentioned games in the pachinko game machine 1 (execution of special game (including reserved management), execution of normal game (including reserved management), jackpot game status, game status, etc.). The game control board 11 has a game control microcomputer 100, a switch circuit 110, an output circuit 111, etc.

[0099] The game control microcomputer 100 mounted on the game control board 11 is, for example, a one-chip microcomputer, and includes a ROM (Read Only Memory) 101, a RAM (Random Access Memory) 102, a CPU (Central Processing Unit) 103, a random number circuit 104, an I / O (Input / Output port) 105, and a real-time clock 106.

[0100] The CPU 103 executes the program stored in the ROM 101 to perform processing to control the progress of the game (processing to realize the functions of the game control board 11). At this time, various data stored in the ROM 101 (variation patterns described below, performance control commands described below, data of various tables referred to when making various decisions described below, etc.) are used, and the RAM 102 is used as the main memory. The RAM 102 is a backup RAM in which the stored contents are saved for a predetermined period of time even if the power supply to the pachinko game machine 1 is stopped in part or in whole. Incidentally, all or part of the program stored in the ROM 101 may be expanded in the RAM 102 and executed on the RAM 102.

[0101] The random number circuit 104 counts numerical data indicating various random numbers (game random numbers) used when controlling the progress of a game in an updatable manner. The game random numbers may be updated by the CPU 103 executing a predetermined computer program (updated by software).

[0102] I / O105 is configured to include, for example, an input port into which various signals (detection signals described below) are input, and an output port for transmitting various signals (signals that control (drive) the first special pattern display device 4A, the second special pattern display device 4B, the normal pattern display device 20, the first hold display device 25A, the second hold display device 25B, the normal pattern hold display device 25C, etc., solenoid drive signals).

[0103] The switch circuit 110 takes in detection signals (such as a detection signal indicating that a game ball has passed or entered and a switch has been turned on) from various switches for detecting game balls (gate switch 21, start port switches (first start port switch 22A and second start port switch 22B), first count switch 23, second count switch 24) and transmits them to the game control microcomputer 100. The transmission of the detection signal indicates that the game ball has passed or entered.

[0104] The switch circuit 110 receives a reset signal, a power-off signal, and a clear signal from the power supply board 17 and transmits them to the game control microcomputer 100. The reset signal is an operation stop signal for stopping the operation of control circuits such as the game control microcomputer 100, and can be output using any of a power supply monitoring circuit, a watchdog timer built-in IC, and a system reset IC. The power-off signal is turned off when a predetermined power supply voltage used in the pachinko game machine 1 exceeds a predetermined value, and is turned on when the period during which the predetermined power supply voltage is below the predetermined value continues for a power-off reference time or longer. The clear signal is turned on in response to, for example, a pressing operation on a clear switch 92 provided on the power supply board 17.

[0105] The output circuit 111 transmits solenoid drive signals (for example, signals to turn on the solenoid 81 and the solenoids 82 and 83) from the game control microcomputer 100 to the solenoid 81 for the normal electric device and the solenoids 82 and 83 for the large prize opening door.

[0106] The pachinko game machine 1 in this embodiment is also provided with a payout control board (not shown). The payout control board is connected to a payout device that is driven to pay out a predetermined number of game balls (e.g., 3 balls, 5 balls, 10 balls, 15 balls, etc.) to a player based on receiving a payout signal, and a game ball detection sensor that is provided in a payout passage through which the game balls paid out by the payout device pass, and it is possible to stop driving the payout device depending on the state of the game ball detection signal received from the game ball detection sensor.

[0107] In addition, a handle sensor for detecting the amount of operation by the player and a touch ring (touch sensor) for detecting that the player is gripping the ball-hitting operation handle 30 are connected to the payout control board, and based on signals input from these sensors, the payout control board controls a launching device capable of launching game balls onto the game board 2. In addition, a signal indicating whether or not the touch ring has been detected and a signal indicating that the game ball has been launched by the launching device are input from the payout control board to the game control microcomputer 100 of the game control board 11.

[0108] The game control board 11 (game control microcomputer 100) supplies presentation control commands (commands that specify (notify) the progress of the game, etc.) to the presentation control board 12 in accordance with the progress of the game as part of the control of the progress of the game. The presentation control commands output from the game control board 11 are relayed by the relay board 15 and supplied to the presentation control board 12. The presentation control commands include, for example, commands that specify various determination results in the game control board 11 (for example, the display results of the special game (including the type of big win), the variable pattern used when executing the special game (described in detail later)), the game status (for example, the start or end of the variable display, the opening status of the big win port, the occurrence of a win, the number of reserved memories, the game status), the occurrence of an error, etc.

[0109] The performance control board 12 is a sub-control board independent of the game control board 11, and has the function of receiving performance control commands and executing performances (various performances according to the progress of the game, including various notifications such as driving the movable body 32, error notifications, and power outage restoration notifications) based on the received performance control commands.

[0110] The performance control board 12 is equipped with a performance control CPU 120, a ROM 121, a RAM 122, a display control unit 123, a random number circuit 124, and an I / O 125.

[0111] The performance control CPU 120 executes a program stored in the ROM 121 to perform processing for executing a performance (processing for realizing the above-mentioned functions of the performance control board 12, including determining the performance to be executed) together with the display control unit 123. At this time, various data (data such as various tables) stored in the ROM 121 are used, and the RAM 122 is used as the main memory.

[0112] The performance control CPU 120 may also instruct the display control unit 123 to execute a performance based on detection signals from the controller sensor unit 35A or the push sensor 35B (signals that are output when an operation by a player is detected and that appropriately indicate the content of the operation).

[0113] The display control unit 123 includes a video display processor (VDP), a character generator ROM (CGROM), a video RAM (VRAM), etc., and executes a performance based on a performance execution instruction from the performance control CPU 120.

[0114] The display control unit 123 causes the image display device 5 to display a performance image by supplying a video signal corresponding to the performance to be executed to the image display device 5 based on an instruction to execute the performance from the performance control CPU 120. Also, a display process is performed to output image data in the display image creation area of ​​the VRAM area specified by the display register as a video signal. In this embodiment, the display image creation area and the drawing area are switched for each V blank. Therefore, drawing is performed in the area assigned as the drawing area in a certain V blank, and in the next V blank, it is switched to the display image creation area, so that the image data drawn in the previous V blank is displayed and output, and drawing is performed in the other area during that time.

[0115] The display control unit 123 further supplies a sound designation signal (a signal designating the sound to be output) to the sound control board 13 and a lamp signal (a signal designating the on / off state of the lamp) to the lamp control board 14 in order to output sound synchronized with the display of the performance image and to turn on / off the game effect lamp 9. The display control unit 123 also supplies a signal for operating the movable body 32 to the movable body 32 or a drive circuit that drives the movable body 32.

[0116] The audio control board 13 is equipped with various circuits for driving the speakers 8L, 8R, and drives the speakers 8L, 8R based on the sound designation signal, causing the speakers 8L, 8R to output the sound designated by the sound designation signal.

[0117] The lamp control board 14 is equipped with various circuits for driving the game effect lamps 9, and drives the game effect lamps 9 based on the lamp signal, turning the game effect lamps 9 on and off in the manner specified by the lamp signal. In this way, the display control unit 123 controls the sound output and the on / off of the lamps.

[0118] In addition, the control of audio output, turning on / off of lamps (such as supplying sound designation signals and lamp signals), and control of movable body 32 (such as supplying signals to operate movable body 32) may be performed by the performance control CPU 120.

[0119] The random number circuit 124 counts numerical data indicating various random numbers (random numbers for performance) used to execute various performances in an updatable manner. The random numbers for performance may be updated by the performance control CPU 120 executing a predetermined computer program (updated by software).

[0120] The I / O 125 mounted on the performance control board 12 is composed of an input port for inputting performance control commands transmitted, for example, from the game control board 11, and an output port for transmitting various signals (video signals, sound designation signals, lamp signals).

[0121] Sub-substrates, such as the performance control board 12, the sound control board 13, and the lamp control board 14, other than the game control board 11, are also called sub-substrates. As in the pachinko game machine 1, multiple sub-substrates may be provided for different functions, or one sub-substrate may be configured to have multiple functions.

[0122] FIG. 3(A) is an explanatory diagram showing an example of the contents of a performance control command used in this embodiment. The performance control command is, for example, a two-byte configuration, with the first byte indicating MODE (command classification) and the second byte indicating EXT (command type). The first bit (bit 7) of the MODE data is always set to "0", and the first bit of the EXT data is set to "0". Note that the command format shown in FIG. 3(A) is only an example, and other command formats may be used. Also, in this example, the control command is composed of two control signals, but the number of control signals constituting the control command may be one, or may be three or more.

[0123] In the example shown in FIG. 3(A), the command 8001H is a first variable display start command that specifies the start of variable display in a special symbol game using the first special symbol in the first special symbol display device 4A. The command 8002H is a second variable display start command that specifies the start of variable display in a special symbol game using the second special symbol in the second special symbol display device 4B. The command 81XXH is a variable pattern designation command that specifies the variable pattern (variable time (variable display time)) of the decorative symbols (also called performance symbols) that are variably displayed in the "left", "middle", and "right" decorative symbol display areas 5L, 5C, and 5R in the image display device 5 in response to the variable display of the special symbol in the special symbol game. Here, XXH indicates an unspecified hexadecimal number, and may be any value that is arbitrarily set according to the instruction contents by the performance control command. In addition, in the variable pattern designation command, different EXT data is set according to the specified variable pattern, etc.

[0124] Command 8CXXH is a variable display result designation command, which is a presentation control command that designates a variable display result such as a special pattern or a decorative pattern. In the variable display result designation command, as shown in FIG. 3(B), for example, different EXT data is set according to the determination result (predetermined result) of whether the variable display result (also called the variable display result) is a "miss" or a "jackpot", and the determination result (jackpot type determination result) of which of several types of jackpot types the variable display result will be when the variable display result is a "jackpot".

[0125] In the variable display result designation command, for example, as shown in FIG. 3(B), command 8C00H is a first variable display result designation command indicating a pre-determined result that the variable display result is "miss". Command 8C01H is a second variable display result designation command notifying a pre-determined result and a jackpot type determination result that the variable display result is "jackpot" and the jackpot type is "jackpot A". Command 8C02H is a third variable display result designation command notifying a pre-determined result and a jackpot type determination result that the variable display result is "jackpot" and the jackpot type is "jackpot B". Command 8C03H is a fourth variable display result designation command notifying a pre-determined result and a jackpot type determination result that the variable display result is "jackpot" and the jackpot type is "jackpot C".

[0126] The command 8F00H is a pattern determination command that specifies the stop (determination) of the variation of the decorative patterns in each of the decorative pattern display areas 5L, 5C, and 5R of the "left", "middle", and "right" in the image display device 5. The command 95XXH is a game state designation command that specifies the current game state in the pachinko game machine 1. In the game state designation command, different EXT data is set according to the current game state in the pachinko game machine 1, for example. As a specific example, the command 9500H is a first game state designation command corresponding to a game state in which neither time-saving control nor probability variable control is performed (low probability low base state, normal state), the command 9501H is a second game state designation command corresponding to a game state in which time-saving control is performed but probability variable control is not performed (low probability high base state, time-saving state), and the command 9502H is a third game state designation command corresponding to a game state in which time-saving control and probability variable control are performed (high probability high base state, probability variable state). In addition, the high probability high base state may simply be referred to as a "high probability state."

[0127] Command A0XXH is a start of jackpot designation command (also called a "fanfare command") that designates the display of a presentation image indicating the start of a jackpot game. Command A1XXH is a large prize opening open notification command that notifies the player that the large prize opening is in an open state during a jackpot game state. Command A2XXH is a large prize opening post-open notification command that notifies the player that the large prize opening has changed from an open state to a closed state during a jackpot game state. Command A3XXH is a end of jackpot designation command that designates the display of a presentation image at the end of a jackpot game.

[0128] In the hit start designation command and the hit end designation command, for example, the same EXT data as the variable display result designation command may be set, so that different EXT data may be set according to the pre-determined result and the big win type determination result. Alternatively, in the hit start designation command and the hit end designation command, the correspondence between the pre-determined result and the big win type determination result and the set EXT data may be made different from the correspondence in the variable display result designation command. In the big win opening notification command and the big win opening after notification command, for example, different EXT data is set according to the number of rounds executed in the big win state (for example, "0" to "10") described later.

[0129] The command B100H is a first start port winning designation command that notifies that a first start condition for executing a special symbol game using a first special symbol in the first special symbol display device 4A has been established based on the occurrence of a start winning (first start winning) caused by a game ball passing through (entering) the first start winning port formed by the winning ball device 6A being detected by the first start port switch 22A. The command B200H is a second start port winning designation command that notifies that a second start condition for executing a special symbol game using a second special symbol in the second special symbol display device 4B has been established based on the occurrence of a start winning (second start winning) caused by a game ball passing through (entering) the second start winning port formed by the variable winning ball device 6B being detected by the second start port switch 22B. Command B300H is a large prize opening entry designation command that notifies the player that 15 prize balls will be paid out when a game ball that has passed through (entered) the first large prize opening or the second large prize opening of the special variable prize ball device 7 is detected by the first count switch 23 or the second count switch 24, resulting in a winning entry.

[0130] The command C1XXH is a first reserved memory number notification command that notifies the first reserved memory number so that the reserved memory number of special figures can be specified. The command C2XXH is a second reserved memory number notification command that notifies the second reserved memory number so that the reserved memory number of special figures can be specified. The first reserved memory number notification command is transmitted from the game control board 11 to the performance control board 12 when the first start port winning designation command is transmitted based on, for example, the game ball passing (entering) the first start port and the first start condition being established. The second reserved memory number notification command is transmitted from the game control board 11 to the performance control board 12 when the second start port winning designation command is transmitted based on, for example, the game ball passing (entering) the second start port and the second start condition being established. In addition, the first pending memory number notification command and the second pending memory number notification command may be transmitted in response to the start of execution of the special game when either the first start condition or the second start condition is met (when the number of pending memories decreases).

[0131] Commands C4XXH and C6XXH are presentation control commands (commands specifying the result of judgment at the time of winning) that indicate the content of the judgment result at the time of winning. Among these, command C4XXH is a design specification command that indicates the judgment result of whether the variable display result is a "jackpot" or not and the type of jackpot (probable win, non-probable win, or sudden probability win) as the judgment result at the time of winning. In addition, command C6XXH is a variation category command that indicates the judgment result of whether the random number value for judging the variation pattern is a "non-reach", "super reach", or "other (normal reach)" variation pattern as the judgment result at the time of winning.

[0132] Instead of the first pending memory number notification command or the second pending memory number notification command, a total pending memory number notification command that notifies the total pending memory number may be sent. In other words, a total pending memory number notification command for notifying an increase (or decrease) in the total pending memory number may be used.

[0133] Command D000H is a V entry notification command for notifying that a game ball has entered the second large entry port during a jackpot game, that is, that a game ball has been detected by the second count switch 24. Hereinafter, in this embodiment, the detection of a game ball by the second count switch 24 during a jackpot game may be referred to as a "V entry." In this embodiment, "V entry" refers to the execution of both time-saving control and probability variable control in a high base state after the end of the jackpot game in which the entry has occurred (being controlled to a high probability high base state).

[0134] Command 9F00H is a customer waiting demonstration display designation command for designating the execution of a customer waiting demonstration display (customer waiting demonstration).

[0135] 3(A) are merely examples, and some of these commands may not be included, or different commands may be used instead of these commands, or different commands may be added. For example, a prize ball number notification command for specifying the number of prize balls to be paid out based on the game balls entering each winning port, a gate passage notification command for notifying that the game balls have passed through the passage gate 41, a notification command for notifying the remaining number of variable display times for which the probability variation control or time reduction control is executed, etc. may be provided.

[0136] FIG. 4 is an explanatory diagram illustrating random numbers counted on the game control board 11. As shown in FIG. 4, on the game control board 11, the random number MR1 for determining the special chart display result, the random number MR2 for determining the big win type, the random number MR3 for determining the variation pattern type, the random number MR4 for determining the variation pattern, the random number MR5 for determining the normal chart display result, and the random number MR6 for determining the initial value of the random number MR5 are controlled so that they can be counted. In addition, random numbers other than these may be used to enhance the game effect. Such random numbers used to control the progress of the game are also called game random numbers.

[0137] The random number circuit 104 may count numerical data indicating a part or all of these random number values ​​MR1 ​​to MR6. The CPU 103 may count numerical data indicating a part of the random number values ​​MR1 ​​to MR6 by updating various numerical data by software using a random counter different from the random number circuit 104, such as a random counter provided in a game control counter setting unit (not shown).

[0138] The random number value MR1 for determining the special symbol display result is a random number value used to determine whether or not to control the variable display result of the special symbol or the like in the special symbol game to a "jackpot" game state, and takes a value in the range of, for example, "0" to "65536." The random number value MR2 for determining the jackpot type is a random number value used to determine the jackpot type to be one of "jackpot A," "jackpot B," or "jackpot C" when the variable display result is a "jackpot," and takes a value in the range of, for example, "0" to "99."

[0139] The random number value MR3 for determining the type of variation pattern is a random number value used to determine the type of variation pattern in the variable display of special patterns and decorative patterns as either "non-reach," "normal reach," or "super reach," and takes a value in the range of "0" to "4095," for example.

[0140] The random number value MR4 for determining the variation pattern is a random number value used to determine the variation pattern in the variable display of special patterns and decorative patterns to one of several types prepared in advance, and takes a value in the range of "0" to "255", for example.

[0141] The random number value MR5 for determining the normal symbol display result is a random number value used to determine whether the variable display result in a normal symbol game by the normal symbol display device 20 is a "normal symbol hit" or a "normal symbol miss", and takes a value in the range of "3" to "13", for example.

[0142] The random number value MR6 for judging the MR initial value is a random number value used to judge the initial value of the random number value MR5, and takes a value in the range of "3" to "13", for example.

[0143] 5 shows an example of the configuration of the display result determination table stored in the ROM 101. In the present embodiment, a display result determination table common to the first special chart and the second special chart is used as the display result determination table, but the present invention is not limited to this, and individual display result determination tables may be used for the first special chart and the second special chart.

[0144] The display result determination table is a table which is referenced to determine whether or not to control the variable display result to a jackpot game state as a "jackpot" before a determined special pattern which is a variable display result is derived and displayed in a special pattern game using a first special pattern by the first special pattern display device 4A or a special pattern game using a second special pattern by the second special pattern display device 4B, based on a random number value MR1 for determining the special pattern display result.

[0145] In the display result determination table, a numerical value (determination value) to be compared with the random number value MR1 for determining the special chart display result is assigned to the special chart display result of "jackpot" or "miss" depending on whether the game state of the pachinko game machine 1 is a normal state or a time-saving state (low probability state), or a probability change state (high probability state).

[0146] In the display result judgment table, the table data indicating the judgment value to be compared with the random number value MR1 for judging the special chart display result is judgment data assigned to the decision result of whether or not to control the special chart display result to a jackpot game state as a "jackpot". In the display result judgment table, when the game state is a probability change state (high probability state), more judgment values ​​are assigned to the special chart display result of a "jackpot" than when the game state is a normal state or a time-saving state (low probability state). As a result, the probability that the special chart display result is determined to be a "jackpot" and controlled to a jackpot game state is higher (about 1 / 30 in this embodiment) than the probability that the special chart display result is determined to be a "jackpot" and controlled to a jackpot game state when the pachinko game machine 1 is in a time-saving state (low probability state) (about 1 / 300 in this embodiment). That is, in the display result judgment table, judgment data is assigned to the decision result of whether or not to control to a jackpot game state so that when the game state in the pachinko game machine 1 is in a probability variable state (high probability state), the probability of deciding to control to a jackpot game state is higher than when it is in a normal state or a time-saving state.

[0147] FIG. 6(A) shows an example of the configuration of a jackpot type determination table stored in the ROM 101. The jackpot type determination table in this embodiment is a table that is referenced to determine the jackpot type to one of a plurality of types based on the random number value MR2 for jackpot type determination when it is determined that the special symbol display result is a "jackpot" and the jackpot game state is controlled. In the jackpot type determination table, a number (determination value) to be compared with the random number value MR2 for jackpot type determination is assigned to a plurality of jackpot types such as "jackpot A", "jackpot B", and "jackpot C" depending on whether the special symbol that is variably displayed (variably displayed) in the special symbol game is the first special symbol (special symbol game by the first special symbol display device 4A) or the second special symbol (special symbol game by the second special symbol display device 4B).

[0148] Here, the jackpot type in this embodiment will be explained with reference to Fig. 6(B). In this embodiment, the jackpot types are jackpot A, jackpot B, and jackpot C, for which time-saving control is executed for a maximum of 100 variable displays after the end of the jackpot game state. In addition, these jackpots A, B, and C are also jackpots for which probability variable control is executed for a maximum of 100 variable displays after the end of the jackpot game by the game ball entering the second large winning hole (so-called V winning) in the sixth round of the jackpot game state.

[0149] The jackpot game state due to "Jackpot A" is a jackpot (6 rounds and jackpot where V cannot be won) game state in which a round in which the first large prize entry port is changed to an open state advantageous to the player in the 1st to 6th rounds is repeated 6 times; the jackpot game state due to "Jackpot B" is a jackpot (6 lands and jackpot where V can be won) game state in which the first large prize entry port is changed to an open state advantageous to the player in the 1st to 5th rounds, while the second large prize entry port is changed to an open state advantageous to the player in the 6th round; and the jackpot game state due to "Jackpot C" is a jackpot (10 lands and jackpot where V can be won) game state in which the first large prize entry port is changed to an open state advantageous to the player in the 1st to 5th rounds and the 7th to 10th rounds, while the second large prize entry port is changed to an open state advantageous to the player in the 6th round.

[0150] In this embodiment, at least the time-saving control is executed after the jackpot gaming state ends, and if a jackpot occurs while the time-saving control is being executed, the time-saving control (and the special bonus control) is executed again after the jackpot gaming state ends, resulting in a so-called consecutive jackpot state in which the jackpot gaming state occurs continuously without going through the normal state.

[0151] In this embodiment, an example is shown in which there are three types of jackpots, jackpot A to jackpot C, but the present invention is not limited to this, and there may be two or less types of jackpots, or four or more types of jackpots.

[0152] Also, as shown in Fig. 6(A), in the jackpot type determination table, the allocation of the determination value for the jackpot type of "jackpot A", "jackpot B", and "jackpot C" differs depending on whether the variably displayed special chart is the first special chart or the second special chart. That is, when the variably displayed special chart is the first special chart, a predetermined range of determination values ​​(values ​​in the range of "0" to "49") are assigned to the jackpot types of "jackpot A" and "jackpot B" with fewer rounds, while when the variably displayed special chart is the second special chart, no determination value is assigned to the jackpot types of "jackpot A" and "jackpot B". By such a setting, the ratio of determining the jackpot type to "jackpot A" or "jackpot B" with a small number of rounds can be made different between the case where the jackpot type is determined to be one of a plurality of types in the special chart game using the first special chart by the first special chart display device 4A and the case where the jackpot type is determined to be one of a plurality of types in the special chart game using the second special chart by the second special chart display device 4B. In particular, since the jackpot type is not determined to be "jackpot A" or "jackpot B" and controlled to a jackpot state with a small number of rounds in the special chart game using the second special chart, for example, in a game state where the game ball is likely to enter the second start winning hole formed by the variable winning ball device 6B due to the high opening control accompanying the time reduction control, it is possible to prevent the frequent occurrence of a jackpot state with a small number of winning balls and a decrease in the interest in the game.

[0153] (Board configuration 2) 2 and 7, a plurality of input components such as various switches and sensors that detect input conditions according to the progress of a game are connected to the game control board 11. The input components include, for example, detection switches that detect operations by a player, detection switches that detect the passage of game media such as game balls and medals, sensors that identify the positions of movable objects used in a game such as reels, detection switches used for various settings such as the player's advantage, detection switches that detect the opening of a door, abnormalities, etc.

[0154] In addition, as shown in FIG. 7, the game control board 11 is equipped with an input circuit (input circuit 111 shown in FIG. 2) that detects input signals from these input components, and input data that specifies the detection status of the input signal from the input component by the input circuit is transmitted to the game control microcomputer 100 and is used to control the game by the game control microcomputer 100.

[0155] In addition, as shown in Fig. 7, a plurality of output components, such as displays, LEDs, motors, solenoids, etc., that perform output control according to the progress of the game are connected to the game control board 11. The output components are, for example, displays (such as the first special symbol display device 4A and the second special symbol display device 4B shown in Fig. 2) that perform display according to the lottery result, displays that display the progress of the game and the status of the gaming machine, displays that instruct the player on the operation mode, LEDs that indicate the game status, LEDs that notify the occurrence of an abnormality, solenoids that operate movable parts used in the game, etc.

[0156] In addition, as shown in FIG. 7, the game control board 11 is provided with an output circuit that outputs an output signal to a corresponding output component based on output data transmitted from the game control microcomputer 100, and the game control microcomputer 100 controls the output component in accordance with the progress of the game by transmitting output data to the output circuit.

[0157] In addition, the game control microcomputer 100, the input circuit (switch circuit 110 shown in Figure 2) and the output circuit (output circuit 111 shown in Figure 2) are connected via a data bus, and the transmission of input data from the input circuit to the game control microcomputer 100 and the transmission of output data from the game control microcomputer 100 to the output circuit are performed via a shared data bus.

[0158] In addition, not all input circuits are connected via a shared data bus; some input circuits are connected directly to the game control microcomputer 100 without going through a data bus, and input data is transmitted from the input circuits to the game control microcomputer 100 without going through the shared data bus.

[0159] In addition, all of the output circuits are configured to be connected via a shared data bus, but some of the output circuits may be connected directly to the game control microcomputer 100 without going through a data bus, and output data may be transmitted from the game control microcomputer 100 to the output circuit without going through a shared data bus.

[0160] In addition, the data bus is connected to an external output terminal, so that the output data from the game control microcomputer 100 is output to an external device as an external output signal, and the external device can use the output data output as an external output signal to inspect the performance of the game machine, etc.

[0161] The game control board 11 has electronic components mounted on one side and no electronic components mounted on the other side where the terminals of the electronic components are soldered; in the following, the side where the electronic components are mounted is referred to as the mounting side, and the side where the electronic components are not mounted and where the terminals of the electronic components are soldered is referred to as the solder side.

[0162] FIG. 8 is a diagram showing the mounting surface of the game control board 11 in this embodiment, and FIG. 9 is a diagram showing the solder surface of the game control board 11 in this embodiment.

[0163] As shown in Fig. 8 and Fig. 9, the game control board 11 is rectangular with a pair of short sides extending vertically and a pair of long sides extending horizontally, and is made of an insulating printed board. In addition, the game control board 11 has a plurality of through holes penetrating the mounting surface and the soldering surface, and a plurality of wiring patterns made of conductors are formed on the mounting surface and the soldering surface of the game control board 11 so as to appropriately connect the through holes. In addition, in the area where the wiring patterns are not formed on the mounting surface and the soldering surface of the game control board 11, an insulating area made of an insulator and a ground area made of a conductor and constituting a ground are formed. The ground area is a solid ground formed over almost the entire area of ​​the mounting surface and the soldering surface of the game control board 11 except the area where the wiring patterns and the insulating area are formed.

[0164] As shown in Fig. 8, the mounting surface has more wiring patterns extending in the vertical direction than those extending in the horizontal direction, while the solder surface has more wiring patterns extending in the horizontal direction than those extending in the vertical direction, as shown in Fig. 9. As a result, the wiring patterns extending in the vertical direction are concentrated on the mounting surface, and the wiring patterns extending in the horizontal direction are concentrated on the solder surface, minimizing the need for designs that require detouring wiring patterns when vertical and horizontal wiring patterns intersect.

[0165] Also, as shown in Figure 9, the wiring patterns arranged on the solder side often have wires that extend in the same horizontal direction as the long side, and so the distance of the wiring patterns is often longer than that of the wiring patterns arranged on the mounting side. However, as mentioned above, electronic components are mounted only on the mounting side and not on the solder side, which prevents the relatively long wiring patterns arranged on the solder side from being obstructed by the electronic components.

[0166] Furthermore, when the wiring pattern formed on the solder surface is branched, one of the branched wiring patterns is formed on the solder surface and the other is formed on the mounting surface via a through hole, so that the branching occurs without having to detour one of the branched wiring patterns or intersecting one of the branched wiring patterns with the other wiring pattern on the same surface.

[0167] FIG. 10 is a diagram showing the mounting surface of the game control board 11 in this embodiment on which the input circuit and the output circuit are mounted.

[0168] As shown in FIG. 10, electronic components such as the above-mentioned game control microcomputer 100, input circuits, and output circuits are mounted on the mounting surface of the game control board 11. These electronic components include electronic components having one or more rows of terminals each consisting of a plurality of terminals arranged in one direction. Most of the electronic components having these terminal rows are arranged along the long side of the game control board 11, that is, arranged in the horizontal direction. As described above, the mounting surface has a high proportion of wiring patterns extending vertically, and electronic components having terminal rows are often arranged along the long side of the game control board 11, that is, arranged in the horizontal direction, so that the wiring patterns extending vertically can be connected to the terminal rows arranged horizontally without changing the direction.

[0169] Also, as shown in Fig. 10, the input circuit and output circuit among the electronic components having terminal rows are formed in a rectangular shape, have a concave notch on one of the short sides, and have a model number printed on the surface, so that the orientation of the component can be identified by the orientation of the notch and the printing direction of the model number. As shown in Fig. 10, the input circuit is arranged so that the notch is on the left side in Fig. 10 and the printing direction of the model number is from left to right, while the output circuit is arranged so that the notch is on the right side in Fig. 10 and the printing direction of the model number is from right to left, so that it is possible to identify whether these electronic components are input circuits or output circuits by the position of the notch and the printing direction of the model number.

[0170] Figure 11 is a diagram showing the configuration of a data bus formed on the solder side of the game control board 11 in this embodiment, and Figure 12 is a diagram showing the wiring pattern branching off from the data bus on the mounting surface of the game control board 11 in this embodiment.

[0171] As described above, the game control board 11 is formed with a data bus that is used for transmitting input data from the input circuit to the game control microcomputer 100 and for transmitting output data from the game control microcomputer 100 to the output circuit. The data bus formed on the game control board 11 of this embodiment is composed of eight wiring patterns extending horizontally on the solder surface, and as shown in Fig. 11, the eight wiring patterns are formed so as to extend horizontally from through holes to which the terminals of the game control microcomputer 100 mounted on the left side of the game control board 11 are connected to the right side. The data bus and electronic components such as the input circuit and output circuit are connected by wiring patterns formed so as to branch out to the mounting surface side through the through holes and extend vertically in the up-down direction, as shown in Fig. 12.

[0172] In this way, when the game control microcomputer 100 and electronic components such as input circuits and output circuits separated in the horizontal direction are connected via a data bus, the terminals of the game control microcomputer 100 are first connected to the data bus on the solder surface extending in the horizontal direction, and then branched to the wiring pattern on the mounting surface side extending in the vertical direction toward the electronic components through the through holes at the positions where the electronic components are mounted, and then connected to the electronic components. Therefore, it is not necessary to detour the wiring pattern branched from the data bus, and the game control microcomputer 100 and electronic components separated in the horizontal direction can be efficiently connected. In addition, since the wiring pattern constituting the data bus is formed on the solder surface on which the electronic components are not mounted, the data bus is less susceptible to noise from the electronic components, and further, since the data bus and the electronic components are connected by the wiring pattern branched to the mounting surface side through the through holes, the wiring pattern on the mounting surface side is short, and it is less susceptible to noise from the electronic components between them.

[0173] As shown in FIG. 11, the wiring pattern extending in the horizontal direction that constitutes the data bus is not formed in a straight line, but is divided into a plurality of wiring patterns extending in the horizontal direction. The length (L1 to L8) of each divided wiring pattern is formed shorter than the antenna length (λ (bus clock) / 2) at which resonance is maximized according to the bus clock (frequency used when transmitting data on the data bus) when transmitting data on the data bus. Therefore, the wiring pattern that constitutes the data bus has an antenna length corresponding to the bus clock, and it is prevented from emitting unintended radio waves due to resonance. Furthermore, even if the length is half the antenna length corresponding to the bus clock, strong resonance may occur due to reflection on the surface of the board. Therefore, the length (L1 to L8) of each divided wiring pattern is formed to be a length that is not half the antenna length at which resonance is maximized according to the bus clock, and it is prevented from emitting radio waves due to strong resonance caused by reflection on the surface of the board.

[0174] Although the bus clock differs depending on the game control microcomputer 100 and oscillator implemented, the length (L1 to L8) of each divided wiring pattern is shorter than the antenna length at which resonance is maximized according to the bus clock with the maximum expected frequency, and is formed to be a length that is not 1 / 2 the antenna length at which resonance is maximized according to the bus clock with the maximum expected frequency. Therefore, even if data is transmitted with a bus clock with a frequency lower than the maximum expected frequency, unintended radio waves are prevented from being generated.

[0175] As shown in Fig. 11, the horizontal wiring patterns divided into multiple parts that make up the data bus are connected to each other via a wiring pattern that extends diagonally right or left, i.e., in a direction different from the direction of the horizontal wiring patterns divided into multiple parts. In addition, the horizontal wiring patterns divided into multiple parts and the diagonally right or left wiring patterns are connected by bending at an obtuse angle. This prevents unintended radio waves from being emitted from the bent parts of the wiring patterns.

[0176] Also, as shown in FIG. 11, the wiring patterns are branched out to the wiring pattern on the mounting surface side (the wiring pattern connected to A to F shown in FIG. 12) through through holes (A to F shown in FIG. 11) provided on the diagonal wiring pattern that connects the horizontal wiring patterns divided into multiple parts, and the wiring pattern that constitutes the data bus is branched out using the diagonal wiring pattern that connects the horizontal wiring patterns divided into multiple parts.

[0177] In the game control board 11 in the embodiment, in order to make the length of the horizontal wiring pattern shorter than the antenna length at which resonance is maximized, the horizontal wiring pattern is divided into multiple wiring patterns, and the multiple divided horizontal wiring patterns are connected to each other by a diagonal wiring pattern formed on the same solder surface, but the multiple divided horizontal wiring patterns may be connected to each other by a wiring pattern formed on the mounting surface side, that is, the horizontal wiring patterns may be formed alternately on the solder surface and the mounting surface so that the length of the horizontal wiring pattern is shorter than the antenna length at which resonance is maximized. In such a configuration, it is preferable to branch the horizontal wiring pattern at the point where it switches from the solder surface or mounting surface to the other surface, and by using such a configuration, it is possible to branch the wiring pattern that constitutes the data bus without detouring the wiring pattern after branching or crossing on the same surface.

[0178] Figure 13 is a diagram showing the configuration of the ground area formed on the mounting surface of the game control board 11 in this embodiment, and Figure 14 is a diagram showing the configuration of the ground area formed on the solder surface of the game control board 11 in this embodiment.

[0179] 13 and 14, a ground area is formed on almost the entire mounting surface and soldering surface of the gaming control board 11, except for the area where the wiring pattern and insulating area are formed. The ground area formed on the gaming control board 11 is composed of a first ground area and a second ground area that are electrically separated by an insulating area. On both the mounting surface and the soldering surface, the first ground area is formed in the left area of ​​the gaming control board 11, and the second ground area is formed in the right area of ​​the gaming control board 11.

[0180] As shown in FIG. 13, electronic components (low-voltage components) to which wiring patterns for transmitting low-voltage (Vcc (+5V) in this embodiment) signals, such as the game control microcomputer 100, input circuits, and output circuits, are connected are mounted in the left-hand region where the first ground region is formed, and the ground terminals of the low-voltage components are connected to the first ground region. On the other hand, electronic components (high-voltage components) to which wiring patterns for transmitting high-voltage (VLD (+24V) in this embodiment), such as drive circuits for operating motors and solenoids, are connected are mounted in the right-hand region where the second ground region is formed, and the ground terminals of the high-voltage components are connected to the second ground region. This prevents unintended current from flowing back from the high-voltage components to the low-voltage components through the ground region. In addition, since the first ground region and the second ground region are formed on the opposing sides of the game control board 11, they are prevented from interfering with each other even if a potential difference occurs temporarily.

[0181] Furthermore, as shown in FIG. 15, a capacitor is provided between the first ground area and the second ground area, and this capacitor prevents current from flowing from one ground area to the other even if a potential difference temporarily occurs between the first ground area and the second ground area.

[0182] 13 and 14, an insulating region where no wiring pattern is formed between the first ground area and the second ground area is formed on the mounting surface and the solder surface, so that the first ground area and the second ground area are electrically isolated from each other. Furthermore, the first ground area and the second ground area on the mounting surface and the first ground area and the second ground area on the solder surface are formed to overlap each other, and the insulating region separating the first ground area and the second ground area on the mounting surface and the insulating region separating the first ground area and the second ground area on the solder surface are also formed to overlap each other, so that even if a potential difference temporarily occurs from one surface of the mounting surface to the other surface of the solder surface, they are prevented from interfering with each other.

[0183] Figure 16 is a diagram showing the configuration of the connector mounted on the mounting surface of the game control board 11 in this embodiment, Figure 17 is a diagram showing the wiring pattern around the connector formed on the solder surface of the game control board 11 in this embodiment, and Figure 18 is a diagram showing the game control board 11 in this embodiment stored in a board case.

[0184] 16, the game control board 11 is mounted with a plurality of connectors CN1 to CN7 for connecting wiring from outside the game control board 11 near the lower side of the mounting surface. The wiring from the game control board 11 includes wiring for inputting or outputting signals related to the advantageous degree of the game, such as a signal for triggering a lottery, a signal for shifting a set value that defines the advantageous degree of the player, such as the lottery probability, to a changeable state, a signal for changing the set value, a signal for displaying information advantageous to the player on an external display, wiring for inputting a detection signal for an error release operation, and wiring as a supply line for a backup power source.

[0185] As shown in Fig. 16, the terminals provided on the connectors CN1 to CN7 are not directly connected to the wiring pattern formed on the mounting surface, i.e., the surface on which the connectors CN1 to CN7 are mounted, but are connected to the wiring pattern formed on the solder surface, i.e., the surface opposite to the surface on which the connectors CN1 to CN7 are mounted, as shown in Fig. 17. On the other hand, as shown in Fig. 16, no wiring pattern is formed around the mounting parts of the connectors CN1 to CN7 on the mounting surface, and information related to the connectors, such as connector numbers, is printed around the mounting parts. Note that the information printed around the mounting parts of the connectors CN1 to CN7 is not limited to the connector numbers, and may be information related to the number of terminals, the direction of the connectors, and the connection destination, etc.

[0186] As shown in FIG. 17, the wiring patterns connected to the terminals provided on the connectors CN1 to CN7 on the solder side are arranged on the opposite side to the side connected to the terminals. At the end, the solder surface is connected to the wiring pattern on the mounting surface through a through hole. In particular, the through holes a to h shown in Fig. 16 and Fig. 17 are through holes to which terminals of electronic components are connected, and are provided at locations where the wiring patterns connected to the terminals provided on the connectors CN1 to CN7 are first connected to the electronic components. For this reason, the solder surface can be connected to the wiring pattern on the mounting surface by using the through holes for connecting to the electronic components.

[0187] As shown in Figures 18(A) and 18(B), the game control board 11 is attached to the game machine in a state where it is housed in a board case. The board case can be sealed by a one-way screw, a seal, welding, or the like, and once sealed, it is difficult to open without leaving a trace. For this reason, by attaching the game control board 11 to the game machine in a state where it is housed in the board case, the structure is such that fraudulent acts against the game control board 11 are prevented.

[0188] 18(A) and 18(B), the board case is provided with a covering portion that covers the area around the connectors CN1 to CN7 when the game control board 11 is stored. On the other hand, as shown in Fig. 16, the wiring pattern is not formed in the area of ​​the mounting surface of the game control board 11 that is covered by the covering portion of the board case, but is formed to avoid this area. The covering portion is provided with insertion holes of approximately the same shape as the connectors CN1 to CN7, and the connectors CN1 to CN7 are exposed to the outside through these insertion holes, allowing wiring from the outside to be connected.

[0189] Even when the game control board 11 is stored in the board case in this manner, slight gaps will be created around the connectors CN1 to CN7 in order to connect them to external wiring; however, the terminals provided on the connectors CN1 to CN7 are not directly connected to the wiring pattern formed on the mounting surface, i.e., the surface on which the connectors CN1 to CN7 are mounted, but are connected to the wiring pattern formed on the solder surface, i.e., the surface opposite the surface on which the connectors CN1 to CN7 are mounted, thereby preventing fraudulent acts such as short-circuiting or breaking the wiring patterns connected to the terminals of the connectors CN1 to CN7 around the areas where the connectors CN1 to CN7 are exposed from the board case.

[0190] In addition, the periphery of the mounting portion of the connectors CN1 to CN7 on the mounting surface is covered by a covering portion of the board case, and no wiring patterns, including wiring patterns connected to the terminals provided on the connectors CN1 to CN7, are formed in the area covered by the covering portion, and the wiring patterns connected to the terminals provided on the connectors CN1 to CN7 are connected to the wiring patterns on the mounting surface in areas other than the covering portion, thereby reliably preventing fraudulent acts such as short-circuiting or disconnecting the wiring patterns connected to the terminals of the connectors CN1 to CN7 from around the area where the connectors CN1 to CN7 are exposed from the board case.

[0191] FIG. 19 is a circuit diagram relating to the supply of backup power to the game control microcomputer 100 mounted on the game control board 11 in this embodiment.

[0192] 19, Vcc (+5V) is generated on the power supply board and is connected to the power supply input terminal Vcc of the game control microcomputer 100 mounted on the game control board 11. Vcc (+5V) is also branched off from the line supplied to the game control microcomputer 100 on the power supply board and is connected to the charging capacitor via a backflow prevention diode, and the line branched off between the backflow prevention diode and the charging capacitor is connected to the backup power supply input terminal VBB of the game control microcomputer 100.

[0193] While power is being supplied, Vcc (+5V) is supplied as a driving power source for the game control microcomputer 100 and is charged in the charging capacitor. On the other hand, when the power supply is stopped, the supply of Vcc (+5V) is stopped, and the backup power source VBB charged in the charging capacitor is supplied to the game control microcomputer 100, and the game control microcomputer 100 is supplied with the backup power source VBB, thereby retaining data stored in the RAM of the game control microcomputer 100. In this embodiment, the backup power source is supplied from a power supply board outside the game control board 11, but it may be supplied from a circuit provided in the game control board 11.

[0194] Figure 20 is a diagram showing the wiring pattern for power supply formed on the solder surface of the game control board 11 in this embodiment, and Figure 21 is a diagram showing the relationship between the wiring pattern formed on the mounting surface of the game control board 11 in this embodiment and the wiring pattern for power supply formed on the solder surface.

[0195] As shown in FIG. 20, on the solder surface of the game control board 11, wiring patterns Vcc1-3 for supplying normal power and wiring pattern VBB for supplying backup power are formed as wiring patterns constituting a power supply line. As shown in FIG. 20 and FIG. 21, the wiring patterns Vcc1-3 are formed by wiring patterns formed on the solder surface and wiring patterns formed on the mounting surface, and are connected to electronic components mounted on the game control board 11. On the other hand, as shown in FIG. 20, the wiring pattern VBB is formed only by wiring patterns formed on the solder surface. That is, the wiring pattern VBB is not connected to the wiring patterns formed on the mounting surface, but is connected to the backup power input terminal VBB of the game control microcomputer 100 through only the wiring patterns formed on the solder surface. That is, the wiring pattern VBB to which the backup power VBB from the power supply board is supplied is formed only on the solder surface. For this reason, the wiring pattern VBB to which the backup power supply VBB is supplied does not need to bypass the electronic components mounted on the mounting surface, and the distance of the wiring pattern to the game control microcomputer 100 can be shortened, so that it is less susceptible to external noise and data stored in the RAM is prevented from being corrupted by noise.

[0196] Also, as shown in FIG. 21, a solid ground is formed on the mounting surface in the portion where the wiring pattern VBB is formed on the solder surface side. Therefore, the solid ground formed on the mounting surface blocks noise, so that the wiring pattern VBB on the solder surface side is less susceptible to noise. Also, as shown in FIG. 21, among the wiring patterns formed on the solder surface, the wiring pattern VBB for supplying backup power is formed at a position where it has fewer intersections with the wiring patterns formed on the mounting surface side, particularly the wiring patterns used for signal transmission, in the corresponding region on the mounting surface side, than the wiring patterns Vcc1 to 3 for supplying normal power. Therefore, the influence of noise from the wiring patterns used for signal transmission formed on the mounting surface side on the wiring pattern VBB to which backup power is supplied is minimized.

[0197] In this embodiment, among the wiring patterns formed on the solder surface, the wiring pattern VBB that supplies backup power is formed at a position where it has fewer intersections with the wiring patterns used for transmitting signals formed on the mounting surface side in the corresponding area on the mounting surface side than the wiring patterns Vcc1-3 that supply normal power. However, by forming the wiring patterns formed on the solder surface that transmit signals related to the player's interests, such as signals that trigger a lottery, at a position where it has fewer intersections with the wiring patterns used for transmitting signals formed on the mounting surface side in the corresponding area on the mounting surface side than the wiring patterns that transmit signals that are not directly related to the player's history, such as signals that control output components, the influence of noise from the wiring patterns used for transmitting signals formed on the mounting surface side on the wiring patterns through which signals related to the player's interests are transmitted is minimized.

[0198] Furthermore, among the wiring patterns formed on the solder surface, those that transmit signals of relatively high importance, such as the wiring pattern that transmits a reset signal for the game control microcomputer 100 and the wiring pattern that provides an operating clock to the game control microcomputer 100, are configured to be formed at positions that have fewer intersections with the wiring patterns used for transmitting signals formed on the mounting surface side in the corresponding area on the mounting surface side than the wiring patterns that transmit other signals, thereby minimizing the effect of noise from the wiring patterns used for transmitting signals formed on the mounting surface side on the wiring patterns that transmit signals of relatively high importance.

[0199] Next, the manner in which the wiring pattern on the mounting surface and the wiring pattern on the solder surface in this embodiment intersect will be described using the upper left part of the game control board 11 in Figs. 8 and 9 as an example.

[0200] First, as shown in Fig. 23 to Fig. 25, the game control board 11 in this embodiment is formed by impregnating a resin into a glass cloth and subjecting it to a heat processing treatment, etc., and a conductor layer 11b made of a highly conductive metal such as copper is laminated on both sides of the non-conductive substrate 11a. The above-mentioned wiring pattern and ground area are formed by the conductor layer 1b. Furthermore, a non-conductive coverlay layer 11c is laminated on a part of the conductor layer 11b, and the wiring pattern on the mounting surface and the solder surface of the game control board 11 is electrically, mechanically, chemically, and thermally protected by these coverlay layers 11c.

[0201] Incidentally, the boundaries between the wiring patterns and the ground regions are formed in gaps 11d where the conductor layer 11b is not laminated, so that adjacent wiring patterns and ground regions are insulated from each other.

[0202] Fig. 22 is an enlarged view of the upper left portion of the game control board 11 in Fig. 8 and Fig. 9. On the mounting surface, as a part of the wiring pattern, a signal transmission line for signal transmission is mainly formed, and on the solder surface, as a part of the wiring pattern, a power supply line V for supplying power from the outside via the power supply board 17 to the electronic components mounted on the game control board 11 is mainly formed.

[0203] Furthermore, as shown in Figure 22, a portion of the power supply line V is also formed on the mounting surface via a through hole formed in the game control board 11, and a portion of the signal transmission line is also formed on the solder surface via through holes S1, S2, and S3 formed in the game control board 11.

[0204] The signal transmission lines in this embodiment are wirings for transmitting signals mainly output from the game control microcomputer 100 and signals input to the game control microcomputer 100.

[0205] The signals transmitted by the signal transmission lines include signals used in the progress of play on the pachinko game machine 1, such as signals based on the detection of game balls from the gate switch 21, the first start port switch 22A, the second start port switch 22B, the first count switch 23, and the second count switch 24 via the switch circuit 110, signals for switching the solenoids 81, 82, and 83 ON / OFF via the output circuit 111, and signals for executing variable display of special and normal patterns in the first special pattern display device 4A, the second special pattern display device 4B, and the normal pattern display device 20.

[0206] The voltage required to transmit these signals is lower than the power supply voltage (voltage applied to power supply line V) required for driving other electronic components implemented on the game control board 11, so the voltage applied to the signal transmission line is lower than the voltage applied to power supply line V (comparison of voltages applied to each wiring: power supply line V>signal transmission line).

[0207] In this embodiment, the signal transmitted by the signal transmission line is exemplified as a signal used to progress the game on the pachinko game machine 1 as described above, but the present invention is not limited to this, and the signal transmitted by the signal transmission line may include signals (commands) used to execute a performance, such as the start of a variable display, a changing pattern, a variable display result, stopping of a variable display, a game status, the start timing of a jackpot game, the end timing of a jackpot game, the fact that a game ball has entered a specific winning slot (the fact that a game ball has been detected by a specific switch), the number of reserved memories, etc., as shown in FIG. 3, to the performance control board 12 (performance control CPU 120).

[0208] As described above, a higher voltage is applied to the power supply line V than to the signal transmission line, so in a conventional game control board, there is a risk that noise generated in the power supply line V or electronic components will interfere with the signal transmission line and affect the control of the pachinko game machine 1. For this reason, the invention described in this embodiment is designed to reduce the risk that noise interference with the signal transmission line will affect the control of the pachinko game machine 1, as will be described in detail later.

[0209] As described above, the power supply line V is a wiring for supplying power to electronic components for progressing a game, such as the game control microcomputer 100, and therefore, together with the signal transmission line, it is a wiring that plays an extremely important role. However, like the signal transmission line, there is a risk that noise generated in the signal transmission line or electronic components may interfere with the power supply line and affect the stable power supply to the electronic components. For this reason, as will be described in detail later, the invention described in this embodiment is designed to reduce the risk that noise interference with the power supply line V may affect the stable power supply to the electronic components (such as the game control microcomputer 100 mounted on the game control board 11) in the pachinko game machine 1.

[0210] As shown in FIG. 26, the power supply line V is a wiring that is connected to electronic components (low-voltage components) and ground with a rated voltage of, for example, 5 V, and is electrically connected to a surge absorber that prevents the application of sudden, abnormal transient voltages.

[0211] Mounting electrodes including through holes are formed in the middle or at the ends of the signal transmission lines and power supply lines V in the longitudinal direction, and electronic components are connected so as to straddle the two mounting electrodes on the mounting surface side.

[0212] Specifically, as shown in Figures 22 to 25, a diode D1, a resistor R1, and a capacitor C1, each having two terminals, are arranged on the mounting surface in the upper left corner of the game control board 11. The diode D1, resistor R1, and capacitor C1 are aligned on the game control board 11 with their longitudinal sides facing the same direction (in the example shown in Figure 22, the diode D1, resistor R1, and capacitor C1 are aligned with their longitudinal sides facing the upper side of the paper).

[0213] The diode D1 is soldered from the solder side with a terminal on one longitudinal end inserted into a through-hole S1 on one side of the signal transmission line (the lower side of the paper in the example shown in FIG. 22), and a terminal on the other longitudinal end inserted into a through-hole S2 on the other side of the signal transmission line (the upper side of the paper in the example shown in FIG. 22).

[0214] The resistor R1 is soldered from the solder side with a terminal on one longitudinal end inserted into a through-hole S3 on one side of the signal transmission line (the lower side of the paper in the example shown in FIG. 22), and a terminal on the other longitudinal end inserted into a through-hole S4 on the other side of the signal transmission line (the upper side of the paper in the example shown in FIG. 22).

[0215] The capacitor C1 is soldered from the solder surface side with a terminal on one end in the longitudinal direction inserted into a through hole S5 on one side of the signal transmission line (the lower side of the paper in the example shown in FIG. 22), and a terminal on the other end in the longitudinal direction inserted into a through hole S6 on the other side of the signal transmission line (the upper side of the paper in the example shown in FIG. 22). That is, as shown in FIG. 22, the signal transmission line connected to the through hole S1 and the signal transmission line connected to the through hole S2 are electrically connected by a diode D1 arranged on the mounting surface side, the signal transmission line connected to the through hole S3 is electrically connected to the through hole S4 (ground shown in FIG. 27) by a resistor R1 arranged on the mounting surface side, and the signal transmission line connected to the through hole S5 and the signal transmission line connected to the through hole S6 are electrically connected by the capacitor C1 arranged on the mounting surface side.

[0216] 23 to 25, the inner circumferential surfaces of the through holes S1 to S6 are covered with a conductive metal film 11e. That is, the terminals of the diode D1, resistor R1, and capacitor C1 are fixed by solder that has entered the through holes S1 to S6 by being soldered from the solder surface side, and are electrically connected to the signal transmission line via the solder and the metal film 11e.

[0217] These through holes S1 to S6 are all round holes having the same diameter (L1) and a circular shape when viewed in a plane, and the mounting surface side end and the solder surface side end have a metal film 11e formed on the inner surface that is electrically connected to the ground areas and wiring formed on the mounting surface and the solder surface, while the aforementioned gap 11d is formed around the parts excluding the connection parts with these ground areas and wiring, and the through holes are insulated from the adjacent ground areas and wiring.

[0218] As shown in Figures 23 to 25, the tips of the terminals of diode D1, resistor R1, and capacitor C1 protrude toward the solder surface when diode D1, resistor R1, and capacitor C1 are fixed, and are bent toward the center of the longitudinal direction of diode D1, resistor R1, and capacitor C1.

[0219] As shown in Figures 27 and 28, of the diode D1, resistor R1, and capacitor C1 that are arranged on the mounting surface and electrically connected to the signal transmission line, the diode D1 is an electronic component used to rectify current, the resistor R1 is an electronic component used as a pull-down resistor between two devices, and the capacitor C1 is an electronic component used for instantaneous power storage.

[0220] The rated current flowing through diode D1, resistor R1, and capacitor C1 is smaller than the rated current flowing through power supply line V used mainly for power supply on the solder side. Similarly, the rated voltage applied to diode D1, resistor R1, and capacitor C1 is smaller than the rated voltage applied to power supply line V used mainly for power supply on the solder side.

[0221] In the case of the diode D1, resistor R1, and capacitor C1, the rated current flowing through the diode D1 and capacitor C1 is the same, and the rated current flowing through the resistor R1 is smaller than the rated current flowing through the diode D1 and capacitor C1 (rated current relationship: power supply line V>diode D1=capacitor C1>resistor R1). Furthermore, the rated voltages applied to the diode D1 and capacitor C1 are the same, and the rated voltage applied to the resistor R1 is smaller than the rated voltages applied to the diode D1 and capacitor C1 (rated voltage relationship: power supply line V>diode D1=capacitor C1>resistor R1).

[0222] As shown in Fig. 22, the area facing the diode D1 (area between the through holes S1 and S2), the area facing the resistor R1 (area between the through holes S3 and S4), and the area facing the capacitor C1 (area between the through holes S5 and S6) on the mounting surface of the game control board 11 constitute non-conductive areas U1, U2, and U3 in which no conductors constituting any wiring patterns are formed. Among these non-conductive areas U1, U2, and U3, the character "D1" is printed near the through hole S2 in the non-conductive area U1, indicating that the position facing the non-conductive area U1 is the mounting position of the diode D1, the character "R1" is printed near the through hole S4 in the non-conductive area U2, indicating that the position facing the non-conductive area U2 is the mounting position of the resistor R1, and the character "C1" is printed near the through hole S6 in the non-conductive area U3, indicating that the position facing the non-conductive area U3 is the mounting position of the capacitor C1.

[0223] More precisely, as shown in FIG. 22, the letters "D1" are printed in the vicinity of the through hole S2 in the non-conductive region U1 to indicate that this is the mounting position of the diode D1, the letters "R1" are printed in the vicinity of the through hole S4 in the non-conductive region U2 to indicate that this is the mounting position of the resistor R1, and the letters "C1" are printed in the vicinity of the through hole S6 in the non-conductive region U3 to indicate that this is the mounting position of the capacitor C1. However, the present invention is not limited to this, and the letters indicating the mounting positions of these diode D1, resistor R1, and capacitor C1 may be printed not only in each of the non-conductive regions U1 to U3, but also in a position overlapping with the power supply line V on the solder side, as long as it is possible to identify the mounting positions of these electronic components.

[0224] In addition, in this embodiment, the mounting positions of the diode D1, resistor R1, and capacitor C1 are indicated by letters such as "C1," "R1," and "C1," but the present invention is not limited to this, and the mounting positions of these diode D1, resistor R1, and capacitor C1 may be indicated by symbols or marks that simplify each electronic component, other than letters.

[0225] Next, the power supply lines V will be described. As shown in Figs. 22 to 25, the power supply lines V are formed on the solder surface of the game control board 11. The width dimension H1 of the power supply lines V is formed to be longer than the width dimension H2 excluding the through-hole of the signal transmission line, so that more current flows through the power supply lines V than through the signal transmission line (relationship of current amount: power supply line V>signal transmission line). Parts of these power supply lines V are extended on the solder surface across the non-conductor areas U1, U2, and U3 of the mounting surface.

[0226] In other words, a portion of the power supply line V in this embodiment is extended to the solder surface so as to pass between through holes S1 and S2 to which the terminal of diode D1 is connected, between through holes S3 and S4 to which the terminal of resistor R1 is connected, and between through holes S5 and S6 to which the terminal of capacitor C1 is connected, with respect to diode D1, resistor R1, and capacitor C1 aligned on the mounting surface side.

[0227] In addition, the solder surface of the game control board 11 faces the diode D1, resistor R1, and capacitor C1 on the mounting surface, and the distance between these diode D1, resistor R1, and capacitor C1 and the power supply line V is longer than the thickness of the game control board 11. Furthermore, the power supply line V is extended across the non-conductive areas U1, U2, and U3, so that the distance between the signal transmission lines excluding the diode D1, resistor R1, and capacitor C1 is also longer than the thickness of the game control board 11. As a result, in this embodiment, the risk that noise generated in the signal transmission lines, diode D1, resistor R1, and capacitor C1 will interfere with the power supply line V and affect the stable power supply to the game control microcomputer 100, etc. is reduced, and the risk that noise generated in the power supply line V will interfere with the signal transmission lines, diode D1, resistor R1, and capacitor C1 and affect the control of the pachinko game machine 1 is reduced.

[0228] Furthermore, in this embodiment, as shown in FIG. 22, the power supply line V is extended across the non-conductive areas U1, U2, and U3 of the mounting surface on the solder side, i.e., the power supply line V faces the diode D1, resistor R1, and capacitor C1 across the game control board 11, thereby reducing the risk of heat dissipation from the power supply line V affecting the diode D1, resistor R1, and capacitor C1, while also reducing the risk of heat dissipation from the diode D1, resistor R1, and capacitor C1 affecting the power supply line V, compared to when the diode D1, resistor R1, capacitor C1, and the power supply line V face each other on the same side of the game control board 11.

[0229] Furthermore, the tips of each terminal of diode D1, resistor R1, and capacitor C1 are bent toward the longitudinal inside of each non-conductor area U1, U2, and U3 (the side of the power supply line V extending across each non-conductor area U1, U2, and U3 on the solder surface) so as to avoid inappropriate contact with the power supply line V or signal transmission lines formed on the solder surface.

[0230] As described above, in this embodiment, as shown in Fig. 22, the power supply line V formed on the solder surface does not cross the signal transmission lines formed on the mounting surface excluding the diode D1, resistor R1, and capacitor C1, while the signal transmission lines formed on the solder surface and the signal transmission lines formed on the mounting surface do cross (in the example shown in Fig. 22, the combination of the signal transmission line connected to the through hole S2 and the signal transmission line connected to the through hole S6, and the combination of the signal transmission line connected to the through hole S3 and the signal transmission line connected to the through hole S5). This is because the signal transmission lines formed on the solder surface and the signal transmission lines formed on the mounting surface are wiring with a common purpose.

[0231] In this embodiment, as described above, the power supply line V formed on the solder surface and the signal transmission line formed on the mounting surface do not intersect, while the signal transmission line formed on the solder surface and the signal transmission line formed on the mounting surface intersect. However, the present invention is not limited to this, and an intersecting portion may also be provided for the power supply line V formed on the solder surface and the power supply line V formed on the mounting surface.

[0232] In addition, at the four corners of the game control board 11 (edges of the game control board 11 shown in FIG. 22), mounting holes SA are formed that penetrate the game control board 11 in the same direction as the through holes S1 to S6. The mounting holes SA are holes for mounting the game control board 11 in a board case (see FIG. 18) by screwing in bolts (not shown). The mounting holes SA are holes that are formed by screwing in bolts (not shown) by screwing in bolts (not shown). It should be noted that, as described above, the inner peripheral surfaces of the through holes S1 to S6 are covered with a metal film 11e, but since the mounting hole SA is a hole into which a bolt is screwed, the inner peripheral surface of the mounting hole SA is not covered with a metal film, unlike the through holes S1 to S6.

[0233] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0234] For example, in the above embodiment, an example was given of the present invention being applied to the game control board 11 of a pachinko game machine 1, but the present invention is not limited to this, and the present invention may be applied to other boards such as the performance control board 12 in a pachinko game machine 1, or may be applied to boards constituting game machines other than a pachinko game machine 1, such as slot machines.

[0235] In the above embodiment, the power supply line V, which is the special wiring pattern of the present invention, is electrically connected to a surge absorber, which is an overvoltage protection circuit, but the present invention is not limited to this, and as a first modification, the power supply line V, which is the special wiring pattern of the present invention, may be electrically connected to an overcurrent protection circuit in addition to or instead of the overvoltage protection circuit. In this way, it is possible to prevent problems caused by an overcurrent flowing through the power supply line V.

[0236] In the above embodiment and variant example 1, an overvoltage protection circuit and an overcurrent protection circuit are electrically connected to the power supply line V, but the present invention is not limited to this, and an overvoltage protection circuit and an overcurrent protection circuit may be electrically connected to the wiring of the power supply line V, such as a signal transmission line.

[0237] In addition, in the above embodiment, the specific wiring pattern in the present invention is a signal transmission line and the special wiring pattern is a power supply line V, that is, the specific wiring pattern is a wiring pattern that transmits signals to electronic components such as each solenoid, and the special wiring pattern is a wiring pattern that supplies power to each electronic component. However, as a modified example 2, as shown in Figure 29, the specific wiring pattern may be a wiring pattern for transmitting signals to electronic components other than the solenoid for controlling the opening of the second start winning port and the large winning port, and the special wiring pattern may be a wiring pattern for transmitting signals to the solenoid for controlling the opening of the second start winning port and the large winning port, or the specific wiring pattern may be a wiring pattern for transmitting light output signals to LEDs or the like that constitute the special pattern, and the special wiring pattern may be a wiring pattern for transmitting signals (winning signals) from each winning port. Alternatively, conversely to the above embodiment, the specific wiring pattern may be a wiring pattern that supplies power to each electronic component, and the special wiring pattern may be a wiring pattern for transmitting signals to electronic components such as each solenoid. Furthermore, when the specific wiring pattern is a wiring pattern that supplies power to each electronic component and the special wiring pattern is a wiring pattern that transmits signals to each electronic component such as a solenoid, an overvoltage protection circuit or an overcurrent protection circuit may be electrically connected to the specific wiring pattern.

[0238] In the above embodiment, as shown in FIG. 22, the non-conductive region U1 is printed with the character "D1" indicating the diode D1 electrically connected to the through holes S1 and S2, the non-conductive region U2 is printed with the character "R1" indicating the resistor R1 electrically connected to the through holes S3 and S4, and the non-conductive region U3 is printed with the character "C1" indicating the capacitor C1 electrically connected to the through holes S5 and S6. However, the present invention is not limited to this. As a third modification, the resistor R1 and the capacitor C1 may be printed with the character "D1" indicating the diode D1 electrically connected to the through holes S1 and S2, the non-conductive region U1 is printed with the character "R1" indicating the resistor R1 electrically connected to the through holes S3 and S4, and the non-conductive region U3 is printed with the character "C1" indicating the capacitor C1 electrically connected to the through holes S5 and S6. are electronic components that do not affect the functions of resistor R1 or capacitor C1, so "R1" indicating resistor R1 is printed in non-conductor region U2 and "C1" indicating capacitor C1 is printed in non-conductor region U3. However, since diode D1 is an electronic component in which the orientation between the two terminals (which terminal is connected to through hole S2) affects the function of diode D1 (the direction in which current flows unilaterally differs), letters or symbols indicating the connection direction of diode D1 may be printed in non-conductor region U1 instead of or in addition to the letters "D1" indicating diode D1.

[0239] Furthermore, in this embodiment, capacitor C1 has been described as an electronic component in which the orientation between the two terminals (which terminal is connected to the through holes S4, S6) does not affect the function of capacitor C1, but the present invention is not limited to this. When capacitor C1 is an electrolytic capacitor or the like, the orientation between the two terminals affects the function of capacitor C1, so that letters or symbols indicating the connection direction of capacitor C1 may be written in the non-conductor region U3 instead of or in addition to the letters "C1" indicating capacitor C1.

[0240] In addition, in the above embodiment, a form was exemplified in which the wiring on the front (mounting surface) of the game control board 11 is a signal transmission line to which the diode D1, resistor R1, and capacitor C1 are electrically connected, and the wiring on the back surface is a power supply line V, but the present invention is not limited to this, and as a fourth modified example, the wiring on the front (mounting surface) of the game control board 11 may be provided as a non-specific wiring pattern of the present invention in a position different from the signal transmission lines in the above embodiment, and the wiring on the back surface may be provided as a non-special wiring pattern of the present invention in a position different from the power supply line V in the above embodiment.

[0241] The wiring as the non-specific wiring pattern and the wiring as the non-special wiring pattern may be wirings with different uses, such as the combination of the specific wiring pattern and the special wiring pattern shown in Fig. 29, or may be wirings with a common use. In particular, when the wiring as the non-specific wiring pattern and the wiring as the non-special wiring pattern have a common use, at least a part of the wiring as the non-specific wiring pattern and the wiring as the non-special wiring pattern may cross or overlap in a plan view as shown in Fig. 22.

[0242] In addition, in the above embodiment, a form in which a diode D1, a resistor R1, and a capacitor C1 are mounted as electronic components on the mounting surface of the game control board 11 is exemplified, but the present invention is not limited to this, and as a variant example 5, the electronic components mounted on the mounting surface of the game control board 11 may include components other than the above-mentioned diode D1, resistor R1, and capacitor C1, such as a transistor or a regulator.

[0243] In addition, in the case where the electronic components mounted on the game control board 11 include those such as some transistors whose mounting position is determined (positioned) by bolts, screws, etc., as variant example 5, positioning holes for positioning these electronic components may be formed in the game control board 11.

[0244] Furthermore, when forming positioning holes in the gaming control board 11, the manufacturing costs of the gaming control board 11 can be reduced by not covering the inner surface of the positioning holes with a metal film like the inner surface of the through holes S1 to S6, and the positioning holes can be made round holes with a different diameter than the through holes S1 to S6 so that workers can easily distinguish between the positioning holes and the through holes S1 to S6 when installing electronic components.

[0245] In addition, in the above embodiment, the width dimension of the power supply line V is made longer than the width dimension of the signal transmission line so that a larger current flows through the power supply line V than through the signal transmission line, but the present invention is not limited to this. In addition to or instead of the width dimension, the thickness dimension of the power supply line V may be made longer than the thickness dimension of the signal transmission line so that a larger current flows through the power supply line V than through the signal transmission line.

[0246] In the above embodiment, as shown in Fig. 22, a form in which one power supply line V is extended on the solder surface side so that the terminals on the mounting surface side face the diode D1, resistor R1, and capacitor C1 connected to each through hole, but the present invention is not limited to this, and multiple wirings including the power supply line V may be extended on the solder surface side so that the terminals on the mounting surface side face the diode D1, resistor R1, and capacitor C1 connected to each through hole. Furthermore, when multiple wirings including the power supply line V are extended on the solder surface side so that the terminals on the mounting surface side face the diode D1, resistor R1, and capacitor C1 connected to each through hole as described above, the wiring that faces the diode D1 together with the power supply line V, the wiring that faces the resistor R1 together with the power supply line V, and the wiring that faces the capacitor C1 together with the power supply line V may be different from each other.

[0247] In the above embodiment, as shown in FIG. 22, a form in which the power supply line V is extended on the solder side so as to span multiple non-conductive areas U1, U2, and U3 formed on the mounting surface is exemplified, but the present invention is not limited to this, and a power supply line or a signal transmission line may be extended in each of the non-conductive areas U1, U2, and U3 so as to cross the power supply line V on the solder side.

[0248] In the above embodiment, the first mounting electrodes to which the first terminals of the diode D1, resistor R1, and capacitor C1 corresponding to the electronic components of the present invention are connected are illustrated as through holes S1, S3, and S5, and the second mounting electrodes to which the second terminals are connected are illustrated as through holes S2, S4, and S6. However, the present invention is not limited to this, and the first mounting electrodes to which the first terminals of the electronic components are connected and the second mounting electrodes to which the second terminals are connected are not limited to hole-shaped ones such as the above-mentioned through holes S1 to S6, and may be clip-shaped ones that clamp the first terminals and second terminals of the electronic components.
