In the description of the gaming machine, front (front), rear (back), left, and right are based on the directions as seen by the player during the game. 【0010】 [Overall view of the gaming machine] FIG. 1 is a diagram for explaining a gaming machine 10 as a pachinko machine. The gaming machine 10 of the present embodiment is an enclosed gaming machine (smart pachinko machine), and the game balls as game media circulate inside the gaming machine and are not given game value on trays such as upper trays. The game value is given as numerical data instead of the game medium (game ball). Note that the configuration of the following embodiments is also applicable to gaming machines that are not enclosed. 【0011】 The gaming machine 10 includes an opening / closing frame that is attached to a frame 11 fixed to the island facility via a hinge 16 so as to be rotatable for opening and closing. The opening / closing frame is composed of a front frame 12 (main body frame) and a glass frame 15 (front frame unit). Also, the left end side of the opening / closing frame is the shaft attachment end side attached to the hinge 16, and the right end side thereof is the opening end side that is opened by rotation. Note that the frame 11 and the front frame 12 constitute an outer frame unit. 【0012】 A game board 30 (see FIG. 2) is disposed on the front frame 12, and a glass frame 15 having a cover glass 14 that covers the front of the game board 30 is attached. The cover glass 14 functions as a game visual recognition area that enables visual recognition of a game area 32 (see FIG. 2) formed on the game board 30. Note that the cover glass 14 is shown as an example of a transparent member, and a plastic cover may be used instead of the cover glass 14. The glass frame 15 functions as a transparent member holding frame that holds the transparent member. 【0013】 The front frame 12 and the glass frame 15 can be opened individually. For example, by opening only the glass frame 15, access can be made to the game area 32 of the game board 30. Also, by opening the front frame 12 while the glass frame 15 is not opened, access can be made to a game control device (main board) 100 (see FIG. 3) etc. disposed on the back side of the game board 30. 【0014】 Various frame components are disposed at the edge portion around the cover glass 14 of the glass frame 15. 【0015】 Decorative devices 18a, 18b, and 18c, capable of illuminating according to the game state, are installed on the upper, right, and left sides of the glass frame 15. Each decorative device 18a, 18b, and 18c houses lighting components such as LEDs 46 (see Figure 4) and is an illuminating device that performs illuminating effects according to the game state. These decorative devices 18a, 18b, and 18c together constitute the frame decorative device 18. 【0016】 Upper speakers 19a are installed in the upper right and upper left corners of the glass frame 15, respectively. In addition to these upper speakers 19a, a lower speaker 19b is provided at the bottom of the gaming machine 10. The lower speaker 19b is installed in the lower part of the front frame 12. These upper speakers 19a and lower speakers 19b emit sound effects, alarm sounds, notification sounds, etc. 【0017】 The performance control device is located on an operation panel that extends left and right from the lower part of the glass frame 15, and includes performance buttons 25 and directional key switches 450. 【0018】 The performance button 25 includes a built-in performance button switch 25a (see Figure 4) that detects when it is pressed down. Multiple performance buttons 25 may be provided. The directional key switch 450 (directional key SW) may be a cross-shaped key switch, or a general type consisting of multiple (for example, four) switches arranged in the forward, backward, left, and right directions. The directional key switch 450 may, for example, use the two left and right switches to increase or decrease (+-) the brightness of the performance LED 46, and the two front and rear switches to increase or decrease (+-) the volume of the speaker 19 (upper speaker 19a and lower speaker 19b). 【0019】 By operating the performance control device (particularly the performance button 25), the player can perform performances that involve the player's input in special symbol variation display games, etc., displayed on the display device 41. For example, the player can select a performance pattern (performance mode) or execute a preview performance that foreshadows the result of the variation display game. Note that the variation display game includes special symbol variation display games (special symbol variation display games), and unless otherwise specified, the term "variation display game" in this specification refers to special symbol variation display games. 【0020】 Furthermore, the content of the display may be changed not only while the variable display game is running, but also when the player operates the display control device while the game is not running. 【0021】 The game state when a variable display game is played consists of multiple game states. The normal game state (normal state) is a game state in which no special game state occurs, and is basically a low-base state with a low payout rate (base value). Special game states are non-normal game states, and include specific game states and special game states. For example, specific game states include the normal electric support state (high base state) in which it is easy to win a prize in the second start prize slot of the normal variable prize winning device 37, and a state in which the probability of a special result (e.g., a jackpot) occurring is high in the variable display game (probability change state, probability change state). Special game states include the jackpot state and the minor prize game state (minor prize state). The high-base state is a state with a higher payout rate (base value) than the normal game state, and the normal electric support state is an example of this. The game control device 100 (game state selection means, setting means) can select (set) one game state from among the multiple game states to become the current game state. 【0022】 Below the glass frame 15 described above, and below the front frame 12, there is an operating handle 24 for controlling the operation of the ball launching device (not shown). 【0023】 The operating handle 24 is located, for example, in the lower right part of the front frame 12 and to the right of the lower speaker 19b. When a player rotates the operating handle 24 as a launching operation, the ball launching device launches the supplied game balls into the game area 32 of the game board 30. The launch speed of the game balls launched from the ball launching device is set to increase as the amount of rotation of the operating handle 24 increases. In other words, the ball launching device can change the launching force, which is the force (speed) at which the game balls are launched into the game area 32, in response to the player's operation of the operating handle 24, and can launch game balls in various launching modes with different launching forces. The launching modes (shooting methods) corresponding to the launching operation (amount of operation) of the operating handle 24 include left-handed shooting (normal shooting), which causes the game balls to flow down on the left side of the game area 32, and right-handed shooting, which causes the game balls to flow down on the right side of the game area 32. 【0024】 In the enclosed gaming machine 10, the game balls ejected from the game area 32 are resupplied to the ball launching device, and there is no exchange of game balls with the outside of the gaming machine 10 (island equipment) or ejection of game balls into trays. 【0025】 Furthermore, the back of the front frame 12 houses the game control device 100, the performance control device 300, and the power supply device 400 that supplies power to the various devices (see Figures 3 and 4). 【0026】 The card unit 201 is a so-called inter-machine dispenser, installed between gaming machine 10 and the adjacent gaming machine on a gaming island. The card unit 201 is located next to gaming machine 10 on its left side and is connected to gaming machine 10 for communication. The card unit 201 has an insertion section 202 into which a card, such as an IC card or other data storage medium, is inserted. The card can store the remaining balance of the deposited money and the number of balls held by the player (the number of game values ​​held). The number of balls held by the player is valid only on the day it is generated, and any balls held after that day may be added to the ball reserve managed by the gaming establishment (the balls are converted into reserve balls). The card may also store the player's personal information or the remaining balance of the payment (prepaid balance). The card unit 201 has a cash input section 203 into which cash can be inserted as banknotes. The amount of money deposited into the cash input section 203 is added to the balance stored on the card. 【0027】 The card unit 201 includes an operation panel 210. The operation panel 210 includes a ball dispensing operation unit 211, a payout operation unit 212, a return operation unit 213, a game ball count display unit 214, and a remaining balance display unit 215. The game ball count display unit 214 and the remaining balance display unit 215 are located within a monitor such as an LCD monitor. The ball dispensing operation unit 211 is operated when increasing the number of game balls held by the game machine (usable game balls, usable game value), which is the number of game balls that the player can use, based on the remaining balance stored on the card. The number of game balls held by the game machine is numerical data managed by the game machine 10. The payout operation unit 212 is operated when increasing the number of game balls held by the game machine based on the number of game balls held on the card. The return operation unit 213 is operated when receiving the return of a card inserted into the card unit 201. The number of game balls held on the card is displayed on the game ball count display unit 214. The remaining balance is displayed in the remaining balance display unit 215. 【0028】 The card unit 201 includes a unit control device 220, which comprises a CPU 220a, a ROM 220b, and a RAM 220c. The CPU 220a performs predetermined control by executing a unit control program. The ROM 220b stores the unit control program. The RAM 220c stores various information that is rewritten during the operation of the card unit 201. The card unit 201 includes an input / output unit 220d that is connected to the gaming machine 10 in a bidirectional manner. The gaming machine 10 may be connected to the input / output unit 220d of the card unit 201 via a frame control device 200. The card unit 201 also includes an input / output unit that connects to a hall computer installed in the gaming parlor (arcade). The hall computer can communicate with a server installed in a data center outside the gaming parlor via a network. 【0029】 The CPU 220a can rewrite the contents stored in the card inserted in the insertion unit 202. The CPU 220a receives a signal indicating the amount of money to be inserted when cash is inserted into the cash insertion unit 203. The CPU 220a also controls the number of balls held by the gaming machine in response to operation signals from the ball dispensing unit 211 or the payout unit 212, and controls the return of the card in response to operation signals from the return unit 213. In addition, the CPU 220a controls the display contents of the game ball count display unit 214 and the remaining balance display unit 215. 【0030】 When the CPU 220a receives a counting signal from the gaming machine 10, it adds the number of gaming balls that can be identified from the counting signal to the card ball count. The counting signal is information that can identify the number of gaming balls held by the gaming machine, to which management is transferred as the card ball count of the card unit 201, and is transmitted from the gaming machine 10 to the card unit 201. 【0031】 The gaming machine 10 includes a ball count display unit 217 that displays the number of available game balls (number of available game balls) that can be used by the player. For example, the ball count display unit 217 is configured with multiple (for example, 6) 7-segment LED lamps arranged in a row, and is capable of displaying multiple (6-digit) numbers. 【0032】 The gaming machine 10 is equipped with a counting operation unit 218, which is operated when a player finishes playing on the gaming machine 10. When the counting operation unit 218 is pressed, it outputs the aforementioned counting signal. The gaming machine 10 is equipped with a counting notification unit 218a, which notifies whether or not the machine is in a counting-ready state. As an example, the ball count display unit 217, the counting operation unit 218, and the counting notification unit 218a are arranged on the front side of the glass frame 15. 【0033】 The number of prize balls awarded to the player (number of game balls awarded, number of game value awarded, amount of game value awarded) is added to the number of balls held by the game machine (number of usable game value balls). In non-sealed game machines, the number of prize balls is awarded as game balls, but in sealed game machines, it is awarded as numerical data. In addition, the number of balls launched into the game area 32 (or the number of balls discharged from the game area 32) becomes the number of game balls used (number of game value balls used) in sealed game machines, and can be stored and managed as numerical data. The new number of balls held by the game machine is obtained by subtracting the number of game balls used from the current number of balls held by the game machine and adding the number of prize balls. 【0034】 [Game board] Next, with reference to Figure 2, the game board 30 of the gaming machine 10 will be described. Figure 2 is a front view of the game board 30 provided in the gaming machine 10. 【0035】 As shown in Figure 2, the game board 30 includes a flat game board body 30a that serves as a mounting base for various components. The game board body 30a is made of wood or synthetic resin, and a game area 32 surrounded by guide rails 31 is provided on the front of the game board body 30a. The game machine 10 is configured to play the game by launching game balls from a ball launching device into the game area 32 surrounded by the guide rails 31. The launching passage 29 guides the game balls from the ball launching device into the game area 32. Windmills, obstacle nails, and the like are arranged in the game area 32 as components that change the direction of the flow of the game balls, and the launched game balls flow down the game area 32 while changing their rolling direction due to these components. 【0036】 A window 40, which serves as the display area for the variable display game, is provided approximately in the center of the game board body 30a. Behind the window 40, a display device 41 is positioned as a performance display device (variable display device) that displays multiple identification pieces of information in a variable manner. The display device 41 is, for example, equipped with a liquid crystal display and is positioned so that the displayed content can be seen from the front side of the game board 30 through the window 40. Note that the display device 41 is not limited to being equipped with a liquid crystal display, but may be equipped with a display such as an organic EL. 【0037】 The display screen (display section) of the display device 41 is provided with multiple variable display areas, and identification information (special symbols) or images that enhance the variable display game are displayed in each variable display area. If there are other displays capable of displaying images in addition to the display device 41, the display device 41 may function as the main display (primary display), and the other displays may function as sub-displays (auxiliary displays). For example, the sub-display may be smaller in size than the display device 41, be movable from near the periphery of the display device 41 to near the center in front as part of the performance, and can also function as a performance movable object 44 (movable mechanism, see Figure 4). 【0038】 An upper display unit 40a and a side display unit 40b are provided on the upper and right sides of the game board 30, respectively. The upper display unit 40a and the side display unit 40b have display LEDs 46 and perform light-emitting effects, and can also perform motion effects (movement effects, rotation effects) as display movable parts 44 (movable parts, see Figure 4). 【0039】 A normal symbol start gate (normal symbol start gate) 34 is provided in the game area 32 to the right of the window section 40. Inside the normal symbol start gate 34, a gate switch (SW) 34a is provided for detecting game balls that have passed through the normal symbol start gate 34 (see Figure 3). When a game ball that has been played into the game area 32 passes through the normal symbol start gate 34, the normal symbol variation display game is executed. 【0040】 A general prize entry point 35 (general prize entry area) is located in the game area 32 to the lower left of the window section 40, and a general prize entry point 35 is also located in the game area 32 to the lower right of the window section 40. The entry of game balls into these general prize entry points 35 is detected by prize entry point switches (SW) 35a (1~n) provided in the general prize entry points 35. 【0041】 In the game area 32 below the window section 40, a starting prize entry opening 36 (first starting opening, starting opening 1, first starting prize entry area) is provided to provide the conditions for starting the special symbol variation display game. In the game area 32 to the right of the window section 40, below the regular symbol starting gate 34, a regular variation prize entry device 37 (regular electric mechanism, regular electric) equipped with a second starting prize entry opening (second starting opening, starting opening 2, second starting prize entry area) is provided. The regular variation prize entry device 37 is equipped with a movable member 37b (movable piece) that rotates forward or to the side to convert it into a state where game balls can easily flow in. When the movable member 37b is in the closed state, game balls cannot enter the regular variation prize entry device 37. When a game ball enters the starting prize entry opening 36 or the regular variation prize entry device 37, the special symbol variation display game is executed. In this embodiment, the starting prize entry opening 36 is designed to make it easier for game balls to enter when playing left-handed, and the normal variation prize entry device 37 is designed to make it easier for game balls to enter when playing right-handed. 【0042】 When the result of the regular variable display game reaches a predetermined stop display pattern, the movable member 37b operates via the regular solenoid 37c (see Figure 3) to open, changing to an open state (an advantageous winning state for the player) that makes it easier for game balls to flow into the regular variable prize winning device 37. If the movable member 37b is not in the open state (winning-easy state), it will be in a closed state (winning-not-easy state, winning-difficult state) that makes it difficult for game balls to flow into the regular variable prize winning device 37. In this embodiment, unlike the regular variable prize winning device 37, the start prize opening 36 does not have a movable member (opening / closing member) and is always in an open state (open state), however, a configuration with a movable member (opening / closing member) is also possible. 【0043】 The movable member 37b is controlled by the game control device 100, which will be described later. The game control device 100 increases the frequency of the easy-to-win state by shortening the variation time of the normal figure variation display game or by making the probability of winning in the normal figure variation display game higher than usual, and by making the duration of the easy-to-win state longer than the duration of the easy-to-win state that occurs in the normal game state without any special games, thereby generating a time-saving state (normal power support state) as a specific game state. In addition, the time-saving state (normal power support state) also occurs in overlapping periods in the probability variation state (excluding the latent probability variation state). 【0044】 Below the normal variable prize winning device 37, in the game area 32, there is a special variable prize winning device 39 which has an opening / closing door 39c that opens the large prize winning area (large prize winning area) when operated by a large prize winning area solenoid 39b (see Figure 3). The special variable prize winning device 39 changes the state of the large prize winning area from a closed state (a blocked state unfavorable to the player) to an open state depending on the result of the special variable display game, thereby making it easier for game balls to flow into the large prize winning area and granting the player predetermined game value (for example, prize balls or the number of time-saving / probability-changing rounds after a big win). A large prize winning area switch 39a (count switch) (see Figure 3) is provided inside the large prize winning area as a detection means for detecting game balls that have entered the large prize winning area. The special variable prize winning device 39 makes it easier for game balls to enter when playing to the right. 【0045】 A special area 86 (a so-called V-prize entry point) is provided inside the special variable prize winning device 39. For example, a big win is confirmed when a game ball enters the special area 86 (V-prize entry point, V-prize area) after the opening door 39c is opened by a minor win. The special area 86 may be kept open for a long time only during a minor win so that game balls can easily pass through. The game control device 100 can detect the passage of a game ball into the special area 86 (V-prize) via a sensor (special area switch 72 described later), and upon detecting a V-prize, it confirms that the game will transition to a big win state (V-prize big win state) after the minor win ends, and transmits information (special area passage command, etc.) indicating that a V-prize has occurred to the performance control device 300 described later. The performance control device 300 can then notify the V-prize on the display device 41, etc. 【0046】 In other words, in this embodiment, the gaming machine 10 is a so-called Type 1 and Type 2 mixed machine (1+Type machine). In this embodiment, when a minor win occurs, the special variable prize entry device 39 is opened, and a game ball enters a specific area 86 (V prize entry) within the special variable prize entry device 39, resulting in a big win. The configuration of this embodiment can also be applied to gaming machines other than Type 1 and Type 2 mixed machines. For example, it can be applied to V-probability machines (V-ST machines) in which a probability variation state (high probability state, specific game state) after the end of a big win is determined when a game ball enters the specific area 86 (V prize entry), and this embodiment can also be partially applied to gaming machines in which there is no specific area 86. 【0047】 When a game ball enters one of the large prize slots, such as the general prize slot 35, the start prize slot 36, the normal variable prize slot 37, or the special variable prize slot 39, the frame control device 200 (see Figure 3) assigns the number of prize balls corresponding to the type of prize slot into which the ball entered as numerical data and adds it to the game machine's ball count (number of usable game balls, number of usable game values). In addition, an out slot 30b is provided in the lower game area 32 to collect game balls that did not enter any prize slots. Furthermore, display LEDs 46 that can light up when a game ball enters or in other situations are provided around the general prize slot 35, the start prize slot 36, the normal variable prize slot 37, and the special variable prize slot 39. 【0048】 Furthermore, outside the game area 32, at the lower right corner of the game board body 30a, is a unified display device 50 that executes special symbol variation display games (special symbol 1 variation display game, special symbol 2 variation display game) and general symbol variation display games. The unified display device 50 is an information display device composed of LED lamps (light-emitting part, light-emitting member) that displays information such as the current game state, and includes display units 51 to 60. 【0049】 The integrated display device 50 includes a first special feature variable display unit 51 (special feature 1 display unit, 8 LED lamps) and a second special feature variable display unit 52 (special feature 2 display unit, 8 LED lamps) for variable display games, which are composed of a collection of multiple LED lamps; a variable display unit 53 (normal display unit, 3 LED lamps) for normal display variable display games; and memory display units (special feature 1 hold display unit 54, special feature 2 hold display unit 55, normal display hold display unit 56) for notifying the number of start memories (holds) for each variable display game. Note that the special feature 1 display unit 51 and special feature 2 display unit 52 may be 7-segment type display units. The special feature 1 hold display unit 54 is composed of 2 LED lamps. The special feature 2 hold display unit 55 is composed of 2 LED lamps. The normal display hold display unit 56 is composed of 2 LED lamps. 【0050】 Furthermore, the integrated display device 50 is equipped with a first game state display unit 57 (first game state indicator, 1 LED lamp) that notifies whether it is time to play to the right (when playing to the right) or to play to the left (normal play), a second game state display unit 58 (second game state indicator, 1 LED lamp) that lights up when a time-saving state occurs to notify the occurrence of a time-saving state, a third game state display unit 59 (third game state indicator, probability state display unit, 1 LED lamp) that indicates that the probability state of a jackpot is in a high probability state when the game machine 10 is powered on, and a round display unit 60 (4 LED lamps) that displays the number of rounds at the time of a jackpot (number of times the special variable prize winning device 39 is opened and closed, upper limit of the number of rounds). 【0051】 In the special display unit 51 and the special display unit 52, the variable display game (symbol variation game) is performed by a variable display (variable display) that repeatedly turns on and off (flashes) identification information (for example, some or all of a group of LED lamps). Multiple types of identification information (symbols) may be displayed alternately. The variable display game may also be performed by all LED lamps on and off (simultaneous flashing of all LEDs), cyclical lighting (any one LED lamp lights up and turns off in a predetermined order at predetermined intervals), or by a predetermined number of LEDs on and off (flashing) or cyclical lighting of all LEDs provided as a display unit for the variable display game. In the general display unit 53, the variable display game (symbol variation game) is also performed by a variable display (variable display, flashing) that repeatedly turns on and off three LED lamps. The general display unit 53 can also be configured as appropriate, similar to the special display unit 51 and the special display unit 52. Thus, in a variable display game, the symbols (special symbols or ordinary symbols) displayed (display mode, display state) on the special symbol 1 display 51, special symbol 2 display 52, or ordinary symbol display 53 change (vary) over time, and therefore, a variable display game is also called a symbol variation game. 【0052】 Next, we will explain the gameplay flow in the gaming machine 10, as well as the details of the regular symbol variation display game and the special symbol variation display game. 【0053】 In the gaming machine 10, the game is played by launching game balls from a ball launching device (not shown) toward the game area 32. The launched game balls move down the game area 32, changing direction due to obstacle nails, windmills, etc., placed at various locations within the game area 32, and either enter the general start gate 34, general prize entry opening 35, start prize entry opening 36, normal variable prize entry device 37, or special variable prize entry device 39, or flow into the out opening 30b located at the bottom of the game area 32 and are discharged from the game area 32. When a game ball enters the general prize entry opening 35, start prize entry opening 36, normal variable prize entry device 37, or special variable prize entry device 39, the number of prize balls corresponding to the type of prize entry opening is added to the number of game balls held by the gaming machine (number of usable game balls). The ball count display unit 217 displays the number of game balls held by the gaming machine after the addition. 【0054】 The regular display start gate 34 is equipped with a gate switch 34a that detects game balls that have passed through the regular display start gate 34. When a game ball passes through the regular display start gate 34, it is detected by the gate switch 34a, and the regular display variation display game is executed based on the determination result of the regular display winning random value (random value for winning determination) extracted at this time. 【0055】 If a game cannot be started, for example, if a game is already in progress and has not yet ended, or if the result of the game is a win and the normal variation prize device 37 has been converted to an open state, when a game ball passes through the normal variation start gate 34, if the normal variation start memory count (normal variation reserve count) is less than the upper limit, that memory count is increased (+1). The game control device 100 (RAM 111c) is a start memory means that stores a predetermined number of extracted random values ​​(normal variation win random values, normal variation random values) as start memory that grants the right to execute the normal variation game, up to a predetermined limit, based on the passage of a game ball through the normal variation start gate 34. If there are multiple types of winning results (normal variation winning symbols) for the normal variation game, normal variation winning symbol random values ​​are also extracted to distribute (draw) the winning results, and both the normal variation win random values ​​and normal variation winning symbol random values ​​are stored as start memory. 【0056】 Thus, the regular diagram start memory (regular diagram hold) stores a regular diagram win random value as a random value for determining whether the regular diagram variation display game is a win or a loss. When this win determination random value matches the determination value, the regular diagram variation display game is a win and a specific result pattern is derived. 【0057】 The regular symbol variation display game (symbol variation game) is executed by a regular symbol display unit 53 provided on the integrated display device 50. The regular symbol display unit 53 consists of LEDs that indicate a win when lit and a mismatch when unlit, representing regular identification information (regular symbol, regular symbol). The regular identification information variation is displayed by blinking these LEDs, and after a predetermined variation display time has elapsed, the result is displayed by turning the LEDs on or off. 【0058】 If the random value of the normal symbol extracted when passing through the normal symbol start gate 34 is a winning value, the normal symbol (normal symbol) displayed on the normal symbol display unit 53 stops at the winning result, and the game enters a winning state (normal symbol winning state). At this time, the normal electric solenoid 37c is driven, causing the movable member 37b to be converted to an open state for a predetermined time (for example, 3 seconds x 2 times), allowing the game ball to enter the normal variable prize winning device 37. The opening time of the movable member 37b of the normal variable prize winning device 37 (for example, 3 seconds) may be called the normal electric opening time. 【0059】 The entry of a game ball into the starting prize slot 36 and into the normal variable prize slot 37 is detected by the starting slot 1 switch 36a (see Figure 3) and the starting slot 2 switch 37a (see Figure 3). Game balls that enter the starting prize slot 36 are detected as starting prize balls for the special figure 1 variable display game and are stored up to a predetermined upper limit (here, 4). Game balls that enter the normal variable prize slot 37 are detected as starting prize balls for the special figure 2 variable display game and are stored up to a predetermined upper limit (here, 4). The game control device 100 (RAM 111c) is a starting storage means that stores a predetermined number of extracted random values ​​as starting memories that grant the right to execute the special figure variable display game, based on the entry of a game ball into the starting prize slot 36 or the starting prize area (starting slot) of the normal variable prize slot 37, up to a predetermined upper limit. 【0060】 When a winning ball is detected to start a special symbol variation display game, various random values ​​are extracted, such as the jackpot random value, the jackpot symbol random value (special symbol random value), and the variation pattern random value. These random values ​​are stored as special symbol start memories in the special symbol hold memory area (part of the RAM) of the game control device 100, up to a predetermined number of times (for example, a maximum of 8 times (4 times x 2)). The number of special symbol start memories stored is displayed on the special symbol 1 hold indicator 54 and the special symbol 2 hold indicator 55 of the unified display device 50 for notifying the number of winning balls that start the game, and is also displayed on the display screen of the display device 41. 【0061】 The game control device 100 executes a special figure 1 variable display game on the special figure 1 display 51 based on a win in the start prize slot 36 or a first start memory (special figure 1 start memory, special figure 1 hold). The game control device 100 also executes a special figure 2 variable display game on the special figure 2 display 52 based on a win in the normal variable prize slot 37 or a second start memory (special figure 2 start memory, special figure 2 hold). 【0062】 Special Symbol 1 Variable Display Game (First Special Symbol Variable Display Game, First Symbol Variable Game) and Special Symbol 2 Variable Display Game (Second Special Symbol Variable Display Game, Second Symbol Variable Game) are performed by displaying identification information (special symbols, special symbols) in a variable manner on the Special Symbol 1 display 51 and Special Symbol 2 display 52, and then stopping to display a predetermined result pattern. The predetermined result patterns that are stopped to display on the Special Symbol 1 display 51 and Special Symbol 2 display 52 include jackpot symbols (jackpot stop symbols), minor jackpot symbols (minor jackpot stop symbols), time-saving symbols (support jackpot stop symbols), and losing symbols (losing stop symbols). 【0063】 Furthermore, the display device 41 executes a decorative special symbol variation display game that displays multiple types of identification information in a variable manner in accordance with each special symbol variation display game. The identification information in the display device 41 consists of numbers, symbols, character patterns, pictures, etc., and for example, the numbers may differ for each of the multiple types of identification information. 【0064】 The decorative symbol variation display game (decorative symbol variation game, performance game) in the display device 41 is performed by starting the variation display (scrolling display or rotating display) of identification information (decorative special symbols, decorative special symbols) composed of the aforementioned numbers, etc., in the order of left (first special symbol), right (second special symbol), center (third special symbol), etc., and then stopping the variation of the symbols sequentially after a predetermined time to display the result of the special symbol variation display game. Multiple types of identification information are displayed in the display device 41 in a changing and variable manner. In this way, the identification information (decorative special symbols) displayed in the display device 41 varies (including changes and movement) according to the passage of time in the decorative symbol variation display game, so the decorative symbol variation display game is also called a symbol variation game. In addition, the display device 41 performs various performance displays, such as the appearance of character images (picture images), to enhance the entertainment value. In addition, a decorative regular symbol variation display game may be implemented in the display device 41, either in place of or in conjunction with the decorative special symbol variation display game, in which identification information (decorative regular symbols, decorative regular symbols) changes over time in accordance with the regular symbol variation display game (symbol variation game) on the regular symbol display device 53, using scrolling display, rotating display, etc., similar to the decorative special symbol variation game. 【0065】 When a game ball enters the starting prize slot 36 or the normal variable prize device 37 at a predetermined timing (when the jackpot random value at the time of prize detection is a jackpot value), a specific result pattern (special result pattern) is derived from the displayed symbols as a result of the special variable display game, and the game enters a jackpot state (special game state). In response to this, the display pattern of the display device 41 becomes the special result pattern (for example, a state where the numbers "777" or similar are aligned). 【0066】 At this time, the special variable prize winning device 39 energizes the large prize winning opening solenoid 39b (see Figure 3), causing the large prize winning opening to change from a closed state to an open state for a predetermined time (for example, 30 seconds). In other words, the large prize winning opening provided in the special variable prize winning device 39 stays wide open for a predetermined time or until a predetermined number of game balls have entered, and during this time, the player is granted the privilege of winning many game balls as prize balls (game value). 【0067】 When a game ball enters the first starting prize entry slot 36 or the normal variable prize entry device 37 at a predetermined timing (when the jackpot random value at the time of prize detection is a minor prize value), a special result pattern (minor prize result pattern) is derived by the displayed symbols as a result of the special variable display game, and the player enters a minor prize state. Correspondingly, the display pattern of the display device 41 becomes the minor prize result pattern. In this embodiment, the jackpot random value is also used to determine minor prizes, but the minor prize value (minor prize determination value) is different from the jackpot value (jackpot determination value). Alternatively, a minor prize random value may be used to determine minor prizes. 【0068】 At this time, the special variable prize winning device 39 energizes the large prize winning opening solenoid 39b (see Figure 3), causing the large prize winning opening to change from a closed state to an open state for a predetermined short time. Note that the total opening time of the large prize winning opening is shorter in the minor win state (minor win game state) than in the big win state (big win game state, special game state), so the game value (number of balls won) that the player can acquire is less in the minor win state than in the big win state. Note that the large prize winning opening is open in both the minor win state and the big win state, but the big win state may be called the first special game state and the minor win state may be called the second special game state. 【0069】 Here, I will explain the difference between a big win and a small win. 【0070】 A big win is a special result that involves the activation of a condition device, while a small win is a special result that does not involve the activation of a condition device. The condition device is activated when a big win occurs in a special symbol variation display game (the big win symbol is displayed when it stops). When the condition device is activated, it means, for example, that a big win state occurs and a specific flag is set to continuously operate the special variation prize device 39, which is a special electric mechanism. The "condition device" may be a software means such as a flag that is turned on and off in software as described above, or a hardware means such as a switch that is turned on and off electrically. 【0071】 Specifically, in the case of a big win, the special variable prize winning device is opened when the big win flag is set, while in the case of a small win, the special variable prize winning device is opened when the small win flag is set. However, if a V-win occurs during a small win state, the condition device will be activated. 【0072】 Furthermore, the Special Feature 2 Variable Display Game is executed with priority over the Special Feature 1 Variable Display Game. There are start memories for both the Special Feature 1 Variable Display Game and the Special Feature 2 Variable Display Game. When the Special Feature 2 Variable Display Game becomes available for execution, the Special Feature 2 Variable Display Game is executed (Special Feature 2 Reserve Priority Processing, Special Feature 2 Priority Variable Display). Alternatively, the Special Feature 1 Variable Display Game and the Special Feature 2 Variable Display Game may be executed in the order in which the winnings (i.e., start memories) occurred (winning order processing). When start memories for the Special Feature 1 Variable Display Game and / or the Special Feature 2 Variable Display Game are generated and the Special Feature 2 Variable Display Game becomes available for execution, the Variable Display Game based on the oldest generated start memory may be executed. Unless otherwise specified, in this embodiment, the Special Feature 2 Priority Variable Display (Special Feature 2 Reserve Priority Processing) is in effect, and the Special Feature 2 Variable Display Game is executed with priority over the Special Feature 1 Variable Display Game. 【0073】 If there is no distinction between the Special Feature 1 Variable Display Game and the Special Feature 2 Variable Display Game, they will simply be referred to as the Special Feature Variable Display Game. 【0074】 [Game control device] Figure 3 is a block diagram of the game control system of the gaming machine 10. The gaming machine 10 is equipped with a game control device 100 (main board) which constitutes the main control means. The game control device 100 is a main control device that comprehensively controls the game, and consists of a game microcomputer 111 (hereinafter referred to as the game microcomputer), an input unit 120 having an input port, an output unit 130 having an output port and drivers, and a data bus connecting the game microcomputer 111, the input unit 120, and the output unit 130. The game microcomputer 111 can receive various signals and data via the input unit 120 and can transmit various signals and data via the output unit 130. 【0075】 The gaming microcontroller 111 may be equipped with an oscillator such as a crystal oscillator, and may be connected to an oscillator circuit (crystal oscillator) that generates the CPU's operating clock, timer interrupts, and a reference clock for the random number generation circuit. The gaming control device 100 and electronic components such as solenoids and motors driven by the gaming control device 100 are made operational by being supplied with a predetermined level of DC voltage, such as DC32V, DC12V, or DC5V, generated by the power supply device 400. 【0076】 The power supply unit 400 includes a normal power supply unit 410 which has an AC / DC converter that generates a DC 32V DC voltage from a 24V AC power supply and a DC / DC converter that generates lower level DC voltages such as DC 12V and DC 5V from a DC 32V voltage, a backup power supply 420 which supplies power voltage to the RAM 111c inside the gaming microcomputer 111 in the event of a power outage, and a control signal generation unit 430 which has a power outage monitoring circuit and generates and outputs control signals such as a power outage monitoring signal that notifies the gaming control device 100 of the occurrence of a power outage and a reset signal that notifies of recovery (restoration, recovery) from a power outage. 【0077】 The backup power supply 420 can be constructed with a single large-capacity capacitor, such as an electrolytic capacitor. The backup power supply 420 is supplied to the game control device 100's game microcontroller 111 (especially the built-in RAM 111c), so that data stored in the RAM 111c is retained even during a power outage or after a power interruption. The control signal generation unit 430 monitors the 32V voltage generated by the normal power supply unit 410, for example, and detects a power outage when it drops to, for example, 17V or below, and outputs a power outage monitoring signal. It also outputs a reset signal after a predetermined time has elapsed from the time of power-on or power restoration. 【0078】 Furthermore, the game control device 100 is provided with a RAM clear switch 112. When the RAM clear switch 112 is pressed down and turned on, an initialization switch signal is generated, and based on this, a RAM initialization process is performed to forcibly initialize the information stored in the RAM 111c in the game microcontroller 111 and the RAM in the frame control device 200. Initialization here basically means clearing the information to zero, but some values ​​such as performance information (base value) may be maintained at their current value without being cleared to zero. Although not particularly limited, the initialization switch signal is read when the power is turned on, and the power failure monitoring signal is repeatedly read in the main loop processing of the main program executed by the game microcontroller 111. The reset signal is a type of forced interrupt signal that resets the entire control system. 【0079】 The RAM clear switch 112 is located on the game control device 100 inside the gaming machine 10, in a position that cannot be operated (inaccessible) unless the front frame 12 (main frame) is opened. In other words, ordinary players cannot access and operate the RAM clear switch 112. The RAM clear switch 112 may be located in a different location from the game control device 100. 【0080】 The gaming microcontroller 111 includes a CPU 111a (Central Processing Unit: microprocessor), a read-only ROM 111b (Read-Only Memory), and a RAM 111c (Random Access Memory) that can be read and written at any time. 【0081】 ROM111b non-volatilely stores immutable information for game control (programs, fixed data, judgment values ​​for various random numbers, etc.). RAM111c is used as a work area for CPU111a and a storage area for various signals and random values ​​during game control. It stores information related to the game (game information) and serves as a storage means that can retain the stored information even in the event of a power outage. 【0082】 Furthermore, ROM111b stores a variation pattern table for determining variation patterns (variation type and variation time) that define, for example, the execution time of the special feature variation display game, the content of the effects, and whether or not a reach state occurs. The variation pattern table is a table for CPU111a to determine a variation pattern by referring to one or more variation pattern random values ​​stored as start memory. The variation pattern table also includes a loss variation pattern table selected when the result is a loss, a jackpot variation pattern table selected when the result is a jackpot, and so on. The pattern table may also include a table for determining the second half variation pattern, which is the variation pattern after a reach state is reached (such as a second half variation group table or a second half variation pattern selection table), and a table for determining the first half variation pattern, which is the variation pattern before a reach state is reached (such as a first half variation group table or a first half variation pattern selection table). 【0083】 The CPU 111a executes the game control program in the ROM 111b to generate control signals (commands) for the frame control device 200 and the performance control device 300, and generates and outputs drive signals for solenoids and display devices to control the entire game machine 10. In addition, although not shown in the diagram, the game microcomputer 111 is equipped with a random number generation circuit to generate random numbers for determining jackpots in the special symbol variation display game, random numbers for special symbols to determine jackpot symbols (jackpot stop symbols), minor jackpot symbols (minor jackpot stop symbols), and time-saving symbols (support jackpot symbols, support jackpot stop symbols), and random numbers for variation patterns to determine variation patterns in the special symbol variation display game (including information on various reach and no-reach variation displays and information on the execution time of the special symbol variation display game). The random number generation circuit can also generate random numbers for determining wins in the random number display game, as well as random numbers for determining the winning symbol. 【0084】 Furthermore, in processing related to the special symbol variation display game, the CPU 111a obtains one of the multiple variation pattern tables stored in the ROM 111b. Specifically, the CPU 111a selects and obtains one of the multiple variation pattern tables based on the game result of the special symbol variation display game (jackpot or miss), the probability state of the special symbol variation display game as the current game state (normal probability state or high probability state), the number of start memories, etc. Here, the CPU 111a acts as a variation distribution information acquisition means that obtains one of the multiple variation pattern tables stored in the ROM 111b when executing the special symbol variation display game. 【0085】 The frame control device 200 is equipped with a CPU, ROM, RAM, input interface, output interface, etc., and controls the payout of prize balls (game value) as numerical data according to payout commands (commands and data) from the game control device 100. 【0086】 The input section 120 of the game microcomputer 111 is connected to the gate switch 34a of the general starting gate 34, the prize entry switch 35a of the general prize entry 35, the starting entry 1 switch 36a in the first starting prize entry 36, the starting entry 2 switch 37a in the second starting prize entry (normal variable prize entry device 37), and the large prize entry switch 39a of the special variable prize entry device 39. The outputs from the gate switch 34a, prize entry switch 35a, starting entry 1 switch 36a, starting entry 2 switch 37a, and large prize entry switch 39a are also supplied from the game control device 100 to a test shooting device (not shown) via the relay board 70. In addition, the detection signals from the starting entry 1 switch 36a and the starting entry 2 switch 37a may be input directly to the game microcomputer 111 in addition to the input section 120. The switches connected to the input section 120 may, for example, detect game balls magnetically. 【0087】 Furthermore, the input unit 120 is connected to a specific area switch 72, a remaining ball discharge switch 73, and an out ball detection switch 74. The specific area switch 72 detects the passage of a game ball into the specific area 86 (V prize slot) (V prize). The remaining ball discharge switch 73 detects game balls that have passed through the remaining ball discharge slot, which discharges game balls from the special variable prize device 39. The out ball detection switch 74 detects all game balls that have been launched into the game area and have finished playing (i.e., all game balls that have passed through the prize slot or out slot 30b). In addition to game balls that have entered the out slot 30b, game balls that have entered the prize slots (first start prize slot 36, second start prize slot (normal variable prize device 37), big prize slot, or general prize slot 35) are guided to the out ball detection switch 74 via a passage (not shown) and are detected. 【0088】 Furthermore, the input unit 120 is connected to various fraud / abnormality sensors 67 (error sensors) that detect errors such as fraud or abnormalities in the gaming machine 10. For example, the fraud / abnormality sensors 67 include a radio wave sensor that detects the emission of radio waves to the gaming machine 10, a magnetic sensor switch for fraud detection provided on the front frame 12 of the gaming machine 10, a glass frame opening detection switch (door opening / closing sensor) provided on the glass frame 15 of the gaming machine 10 for detecting the opening of the glass frame, a front frame opening detection switch (main frame opening detection switch, door opening / closing sensor) provided on the front frame 12 (main frame) for detecting the opening of the front frame, and a vibration sensor that detects vibrations of the gaming machine 10. 【0089】 Furthermore, the input unit 120 receives a signal from the RAM clear switch 112 and supplies it to the game microcontroller 111 via the data bus. Data may also be input from the frame control device 200 to the game control device 100 via the input unit 120. 【0090】 Data is transmitted from the game control device 100 to the performance control device 300 via the output unit 130, for example, by serial communication. Note that the communication between the game control device 100 and the performance control device 300 is unidirectional, preventing the performance control device 300 from inputting signals to the game control device 100. Data may also be transmitted from the game control device 100 to the frame control device 200 via the output unit 130. 【0091】 Furthermore, a buffer 133 can be connected to the output unit 130, and the buffer 133 outputs a test firing signal from the output unit 130 to a test firing device of a certification body (not shown) via the relay board 70. The buffer 133 is a component that is not mounted on the game control device (main board) of a game machine that is a mass-produced product installed in a game parlor (game hall). 【0092】 Furthermore, the output unit 130 is provided with output ports that output opening and closing data for the ordinary electric solenoid 37c, which opens the ordinary variable prize winning device 37; the large prize winning opening solenoid 39b, which opens the special variable prize winning device 39; and the lever solenoid 86b, which operates the lever and opens the specific area 86. In addition, the output unit 130 is provided with a driver that receives the opening and closing data signals, generates solenoid drive signals, and outputs them. 【0093】 Furthermore, the output unit 130 can output the on / off data of the LEDs of the integrated display device 50 as data to be displayed on the integrated display device 50, using the corresponding output port and driver. 【0094】 Furthermore, the output unit 130 can output external information related to the gaming machine 10, such as jackpot information, to the external information terminal 71 using the corresponding output port and driver. The external information terminal 71 can be connected to external devices installed in a gaming parlor (such as information collection terminals or internal management devices (hall computers)), and information related to the gaming machine 10 can be supplied to these external devices. Note that the number of external information terminals 71 may be provided in a number that takes into account the number of types of external information and the number of destinations for outputting external information. 【0095】 Furthermore, the output unit 130 can output the on / off data of the LEDs of the performance display device 152 as data to be displayed on the performance display device 152, using the corresponding output port and driver. 【0096】 In this embodiment, the performance display device 152 consists of multiple (four) 7-segment type (8-segment type if dot Dp is included) displays (LED lamps), but is not limited to this. 【0097】 The performance display device 152 is provided on the game control device 100 (main board), but it may be provided in another location. For example, the performance display device 152 can display performance information such as the payout rate (base value). The performance information is derived based on the number of prize balls (game value) obtained by winning, and may include, for example, the payout rate (base value), the ratio of prize balls, and the number of balls dispensed. 【0098】 The payout rate (base value) is the ratio (percentage) of the total number of prize balls to the number of balls dispensed (or the number of balls launched into the game area 32), and is calculated as (number of balls acquired ÷ number of balls dispensed) × 100 (%). In other words, the payout rate is the number of balls acquired (total number of prize balls) per 100 balls dispensed. The number of balls dispensed can be obtained by counting the signals from the out ball detection switch 74, etc. In enclosed gaming machines, the number of balls acquired (total number of prize balls) is the number of game value (amount of game value) assigned as numerical data. 【0099】 For example, the bonus payout ratio is the percentage (%) of the total number of prize balls obtained from winning in the big prize slot during a jackpot state (number of prize balls obtained by each bonus payout) out of the total number of prize balls obtained from winning in the winning slots during a predetermined period (for example, from the time the gaming machine 10 is powered on until the present) (= so-called consecutive bonus payout ratio). 【0100】 [Safety device (complete function)] Furthermore, the game control device 100 also functions as a safety device. The safety device is a game stopping means (stopping means) that can generate a game stop state (game unplayable state, game prohibited state) in which special symbol variation display games, normal symbol variation display games, and round games (games during big wins or small wins) cannot be played when the operating conditions (predetermined conditions) based on the number of safe balls and the number of balls dispensed are met. In the game stop state, new special symbol variation display games and new normal symbol variation display games cannot be started. The safety device allows for appropriate countermeasures against fraud, such as when the number of safe balls is abnormally high due to fraud, and may also suppress players from becoming addicted to the game. When addiction is suppressed, players can play with peace of mind. 【0101】 In this embodiment, the safety device is a function implemented by software (program) in the game control device 100, and is also called the complete function (or ending function, stop function). Of course, the safety device may also be provided as hardware such as an electrical circuit or circuit board. 【0102】 Furthermore, in this embodiment, the operating conditions for the safety device are that (1) the difference in the number of balls, which indicates the difference between the number of safe balls and the number of balls dispensed during a predetermined period, has reached the difference in balls standard value (predetermined value), and (2) neither a big win nor a small win is occurring. The difference in balls is obtained by subtracting the number of balls dispensed from the number of safe balls during the predetermined period (difference in balls = number of safe balls - number of balls dispensed). Thus, the operating conditions for the safety device consist of two stages of conditions (1) and (2). Note that the difference in balls for condition (1) may be the difference in balls during the predetermined period from the point in time when the difference in balls was at its lowest value to the present, that is, the difference in balls based on the lowest value (the increase in the difference in balls from the lowest value), and may also correspond to the maximum increase in the difference in balls during a day of operation (so-called MY). In addition, the operating conditions may be other; for example, condition (1) may be configured to be that the number of safe balls reaches a predetermined value. Also, condition (2) may be configured to be that the special variable prize winning device is not operating, or that the big prize winning opening is not open. 【0103】 In this embodiment, the number of safe balls is the total number of prize balls (number of acquired balls, number of balls dispensed) that are determined to be awarded during a predetermined period. The number of ejected balls (number of out balls) is the number of game balls ejected from the game area 32 during a predetermined period, and can be counted by counting the signals from the out ball detection switch 74. 【0104】 Alternatively, instead of the number of balls dispensed, the number of balls launched and introduced into the game area 32 may be used, and the difference in balls may be calculated as the number of safe balls minus the number of balls launched. The number of balls launched and the number of balls dispensed may be collectively referred to as the number of balls used (difference in balls = number of safe balls - number of balls used). Foul balls that were launched by the ball launcher but did not reach the game area 32 are excluded from the number of balls launched, and the difference in balls is reduced by -1 for each game ball launched by the ball launcher and increased by +1 for each foul ball. 【0105】 For example, for a difference of less than 90,000 balls, the safety device will be in an inactive state (not activated, not in an activated warning state, not in an activated state, and not in an activated state). For a difference of 90,000 to 94,999 balls, the safety device will be in an activated warning state, indicating that the safety device will be activated. When the difference of 95,000 balls is reached, the safety device will be in an activated warning state, indicating that the safety device will be activated, or in an activated state, indicating that the safety device is activated (activated state). 【0106】 Furthermore, when the number of balls reaches 95,000, the safety device will enter an activation warning state if a big win or a small win is occurring, and will enter an activation state if neither a big win nor a small win is occurring. Therefore, if the safety device is activated before a big win or small win occurs, the game will immediately enter a game stop state (game unavailable state, game prohibited state), and the activation warning state will not occur. Note that the safety device is more likely to be activated before a big win or small win occurs in time-saving states or probability-changing states. 【0107】 On the other hand, when a big win or a small win ends and the game is no longer in a big win or small win state, the safety device switches from an activated warning state to an activated state (operating state). 【0108】 In the operation notification state, the performance control device 300 displays an operation notification (for example, the words "The game will stop soon") on the display device 41. In the operation warning state of the safety device during a minor win or a major win, the performance control device 300 displays an operation warning (for example, the words "The game will stop after the win ends") on the display device 41. 【0109】 When the safety device is activated (not during a minor or major win), i.e., when the game is stopped, the performance control device 300 displays the activation indicator 513 (the words "Stopped") on the display device 41. When the safety device is activated, the game control device 100 sets the safety device activation flag (safety device activation flag) to ON, indicating that the safety device is activated. The safety device activation flag (safety device activation flag) is reset to 0 (safety device activation flag = 0) by the RAM initialization process (RAM clear process), and the safety device is deactivated. 【0110】 In the stopped game state, special symbol variation display games, normal symbol variation display games, and round games (gameplay during big wins or small wins) cannot be played. To achieve this, for example, in the stopped game state, the detection of game balls by the prize entry switch is disabled, the prize entry (winning) is disabled, the solenoid stops so that the big prize entry, specific area 86, normal variation prize device 37, etc. are closed, the launch of game balls from the ball launcher is stopped (prohibited), and the integrated display device 50 and performance display device 152 turn off. In the stopped game state, not only can special symbol variation display games and normal symbol variation display games not be continued, but new special symbol variation display games and new normal symbol variation display games cannot be started. Note that a configuration is also possible in which the launch of game balls is not stopped in the stopped game state. In the stopped game state, all light-emitting parts (LEDs) of the integrated display device 50 and performance display device 152 turn off (all off). However, this is not limited to the above, and in the game stopped state, some of the light-emitting parts (LEDs) of the integrated display device 50 and the performance display device 152 may be lit (partially lit) or all of them may be lit (all lit). Furthermore, in the game stopped state, a security signal may be generated that is output as an external information signal to an external device such as a hall computer, and a test firing signal corresponding to the game stopped state may be output to the test firing device (a configuration in which no test firing signal is output is also possible). In the game stopped state, the performance control device 300 may turn off all of the performance LEDs 46 (all off), or turn on some or all of them. However, during an error, some or all of the performance LEDs 46 may be lit in red. Also, in the game stopped state, the performance control device 300 may stop the audio output from the speaker 19 and make it silent (a configuration that does not make it silent is also possible). 【0111】 [Transition state upon power-on] Depending on the on / off state of the RAM clear switch 112 when the power is turned on, the system transitions to various states (modes). 【0112】 When the power is turned on, if the RAM clear switch 112 is ON, the system will enter the RAM initialization state (RAM clear mode), and the RAM initialization process (RAM clear process) will be executed to initialize RAM 111c. Alternatively, if the RAM clear switch 112 is ON initially, the system may enter a state of RAM clear preparation (initialization preparation), and if the RAM clear switch 112 is turned ON again during the RAM clear preparation state, RAM 111c may be initialized by the RAM initialization process (RAM clear process). The game control device 100 may also output security signals (e.g., 4 msec, 128 msec, etc.) as external information to an external device such as a hall computer via the external information terminal 71 when executing the RAM initialization process. 【0113】 If the RAM clear switch 112 is off when the power is turned on, the system will transition to the normal power restoration state (normal power restoration mode) and will simply be powered back on. 【0114】 [Performance control device] Next, the configuration of the performance control device 300 (sub-board) will be explained using Figure 4. Figure 4 is a block diagram of the performance control system of the gaming machine 10. The performance control device 300 is a sub-control device (sub-board, sub-control means) that can control the image on the display device 41, the sound from the speakers 19a and 19b, the illumination of the performance LED 46, and / or the operation of the performance movable body 44 in response to commands from the gaming control device 100. In other words, the performance control device 300 can control the performances related to the game. The performance LED 46 may be a full-color LED (light-emitting diode) capable of emitting light in various colors. 【0115】 The performance control device 300 includes a control microcontroller 311 (CPU), a VDP (Video Display Processor) 312 which acts as a graphics processor and performs image processing for displaying video on the display device 41 according to commands and data from the control microcontroller 311, and a sound control unit 314 which controls the output of sound in order to play various melodies and sound effects from the speaker 19. 【0116】 The control microcontroller 311 is connected to a ROM 321 that stores programs executed by the CPU and various data, and a RAM 322 that provides a workspace. The control microcontroller 311 also has its own internal RAM (e.g., cache memory) that provides a workspace. 【0117】 The control microcontroller 311 analyzes commands from the game control device 100, determines the display content and instructs the VDP 312 on the content of the output video, instructs the sound control unit 314 on the playback sound, lights up the effect LED 46, controls the drive of the motors and solenoids of the effect movable body 44, and manages the effect time. 【0118】 The VDP312 includes RAM to provide a workspace and a scaler for scaling images. The VDP312 is also connected to an image ROM 325 that stores character images and video data, and an ultra-high-speed VRAM (video RAM) 326 used to expand and process image data such as characters read from the image ROM 325. 【0119】 The sound control unit 314 includes a sound ROM in which sound data, including speech, is stored, and an amplifier circuit for amplifying the speech data. 【0120】 Furthermore, the performance control device 300 is equipped with an interface chip (command I / F) that receives commands transmitted from the game control device 100. The performance control device 300 receives special symbol retention count commands, decorative special symbol commands, variation commands, symbol stop commands, etc., transmitted from the game control device 100 to the performance control device 300 via the command I / F as performance control command signals (performance commands). 【0121】 Furthermore, the performance control device 300 is equipped with a performance LED control circuit 332 that drives and controls the performance LEDs (light-emitting diodes) 46 provided on the game board 30, and a performance movable body control circuit 334 that drives and controls the performance movable bodies 44 (for example, movable parts that work in cooperation with the performance display on the display device 41 to enhance the performance effect) provided on the game board 30, glass frame 15, etc. 【0122】 These control circuits 332 and 334, which drive and control the motors and solenoids of the performance LEDs 46 and the performance movable parts 44, are connected to the control microcontroller 311 via an address / data bus. 【0123】 Furthermore, the performance control device 300 is provided with a switch input circuit 336. The switch input circuit 336 has the function of inputting detection signals indicating the on / off state of the performance button switch 25a built into the performance button 25 provided on the glass frame 15, and detection signals indicating the on / off state of the directional key switch 450, to the control microcontroller 311. The switch input circuit 336 also inputs detection signals from the volume control switch 335, which allows amusement store personnel (staff, manager, administrator) to adjust the volume (maximum volume, etc.) of speakers 19a and 19b to the control microcontroller 311. 【0124】 The normal power supply unit 410 of the power supply unit 400 supplies a desired level of DC voltage to the performance control device 300 and the electronic components controlled by it, which have the configuration described above. 【0125】 [Basic control] Next, the basic control of the gaming machine 10 will be explained. The CPU 111a of the gaming microcomputer 111 of the gaming control device 100 extracts a random value for determining a win in the regular diagram (regular diagram win random value) based on the input of a game ball detection signal from the gate switch 34a provided in the regular diagram start gate 34, compares it with a determination value stored in the ROM 111b, and determines whether the regular diagram variation display game is a win or a loss. 【0126】 Then, the regular display unit 53 displays a regular variation display game in which the identification pattern is displayed in a variable manner for a predetermined time and then stopped. If the result of the regular variation display game is a win, the regular display unit 53 displays a special result pattern and operates the regular solenoid 37c to open the movable member 37b of the regular variation prize winning device 37 for a predetermined time (for example, 3 seconds x 2 times) as described above. If the result of the regular variation display game is a loss, the regular display unit 53 displays a loss result pattern. 【0127】 Furthermore, based on the input of the game ball detection signal from the start port 1 switch 36a provided in the start prize port 36 (first start port), a first start memory is stored. Based on the first start memory, a random value for determining the jackpot of the special figure 1 variable display game (jackpot random value) is extracted and compared with the determination value stored in the ROM 111b to determine whether the special figure 1 variable display game is a win or a loss. 【0128】 Furthermore, based on the input of the game ball detection signal from the start port 2 switch 37a provided in the normal variable prize winning device 37 (second start port), a second start memory is stored. Based on the second start memory, a random value for determining the jackpot of the special figure 2 variable display game (jackpot random value) is extracted and compared with the determination value stored in the ROM 111b to determine whether the special figure 2 variable display game is a win or a loss. 【0129】 The CPU 111a of the game control device 100 then outputs a control signal (performance control command) to the performance control device 300, which includes the judgment result of the special figure 1 variation display game and the special figure 2 variation display game. The special figure 1 display 51 and the special figure 2 display 52 then display the special figure variation display game, which displays the identification symbol as it changes for a predetermined time and then stops. In other words, the game control device 100 is a game control means that controls the progress of the variation display game based on the entry of the game ball flowing down the game area 32 into the starting prize area (first starting prize opening 36, normal variation prize device 37). 【0130】 Furthermore, the performance control device 300 displays a decorative special feature variation display game on the display device 41, corresponding to the special feature variation display game on the special feature 1 display 51 and the special feature 2 display 52, based on commands (control signals) from the game control device 100. In addition, the performance control device 300 performs processing such as setting the performance state, outputting sound from speakers 19a and 19b, and controlling the illumination of various performance LEDs 46, based on commands (control signals) from the game control device 100. In other words, the performance control device 300 constitutes a performance control means that controls the performance related to the game (variation display game, etc.). 【0131】 Then, if the result of the special symbol variation display game is a minor win or a major win, the CPU 111a of the game control device 100 displays the minor win symbol or major win symbol (minor win stop symbol or major win stop symbol) as a special result mode on the special symbol 1 display 51 or the special symbol 2 display 52, and also generates a special game state. In the process of generating the special game state, the CPU 111a, for example, uses the major prize slot solenoid 39b to open the opening / closing door 39c of the special variation prize slot 39, thereby controlling the inflow of game balls into the major prize slot. 【0132】 Then, the game controls the game by keeping the large prize slot open until either a predetermined number of game balls (for example, 10) enter the large prize slot, or a predetermined period of time (for example, 27 seconds or 0.05 seconds) has elapsed since the large prize slot was opened, and this process is continued (repeated) for a predetermined number of rounds (for example, 15, 11, or 2). Furthermore, if the result of the special symbol variation display game is a loss, the game controls the special symbol 1 display 51 and the special symbol 2 display 52 to stop and display a losing symbol (losing stop symbol) as the result of the loss. 【0133】 Furthermore, the game control device 100 can generate a high-probability state (specific game state) as a game state after the end of the special game state, based on the result of the special symbol variation display game. The high-probability state (probability variation state) is a state in which the probability of getting a winning result in the special symbol variation display game is higher than that of the normal probability state. Also, regardless of whether the high-probability state is generated based on the result of the special symbol variation display game 1 or the special symbol variation display game, both the special symbol variation display game and the special symbol variation display game will be in the high-probability state. In the high-probability state (probability variation state), the game control device 100 sets a special symbol high-probability flag to indicate the high-probability state. 【0134】 Furthermore, the game control device 100 can generate a time-saving state (specific game state) as a game state based on the result pattern and number of times the special symbol variation display game is executed. In the time-saving state, the control may be made to put the regular symbol variation display game and the regular variation prize device 37 into a time-saving operation state, and the control is made so that the opening time of the regular variation prize device 37 per unit time is substantially longer than in the normal game state in which no special game is played, thus resulting in a regular power support state. In addition, even in high probability states (normal probability states) excluding the latent probability variation state, the time-saving state is also implemented and regular power support is performed. 【0135】 In addition, during the time-saving mode, the execution time of the special symbol variation display game (special symbol variation time) may also be shortened compared to normal, and time-saving variations of the special symbol variation display game can also be implemented. 【0136】 Furthermore, in the time-saving mode, it is possible to set the number of times the normal variable prize device 37 opens (normal electric opening count) for one winning result in the normal variable display game to a second opening count that is greater than the first opening count (for example, 2 times) (for example, 4 times). Also, in the time-saving mode, it is possible to set the probability of a winning result in the normal variable display game (normal probability, normal win probability) to a higher probability than the normal probability (low probability) in the normal operation state. 【0137】 In the time-saving state, the time required to convert the normal variation prize device 37 to the open state is extended compared to normal by changing one or more of the following: normal variation time, normal variation stop time, normal power release count, normal power release time, and normal variation probability. As a result, in the time-saving state, it becomes easier to win prizes with the normal variation prize device 37 than in the normal game state where no special games are played, and the number of executions of the special variation display game per unit time can be increased compared to the normal game state, and the execution interval of the special variation display game can also be shortened. It is also possible to set multiple types of time-saving states in which different parameters are changed. In addition, the movable member 37b may be set not to open in the normal operation state (normal variation probability is 0). If there are multiple types of normal variation win results (normal variation win symbols), the normal power release time (long opening, short opening) and the number of normal power release counts may be changed according to the type of normal variation win result (normal variation win A, normal variation win B, etc.). Furthermore, the normal train release time and the number of normal train releases associated with each normal train result may be changed depending on the type of time-saving state (normal train support state). Also, the high probability state (probability change state) and the time-saving state can occur independently of each other, and it is possible to have both occur simultaneously or to have only one of them occur. 【0138】 The game control device 100 basically sets a time-saving flag to indicate the time-saving state when the time-saving state is active. However, even if the time-saving flag is set, the low base state, in which the payout rate (base value) is as low as the normal game state because the opening time of the normal variable prize winning device 37 is extremely short, may be treated as a normal game state in which no special gameplay is performed (of course, it may also be treated as a time-saving state). 【0139】 The time-saving state includes a time-saving state that occurs immediately after a jackpot (a time-saving state), a time-saving state that occurs upon reaching the ceiling count without being caused by a jackpot (ceiling time-saving state, b time-saving state, playtime), and a time-saving state that occurs upon the stopping display of time-saving symbols (support jackpot) without being caused by a jackpot (sudden time-saving state, c time-saving state). Furthermore, if the number of special symbol variation display games (excluding the number of games in the probability variation state) executed after power-on or after the end of the jackpot state reaches the ceiling count, the player will enter a time-saving state (playtime) even if they do not win a jackpot or a time-saving symbol. Regarding a time-saving state (b time-saving state, c time-saving state are also acceptable), there may be multiple time-saving states (a1 time-saving state, a2 time-saving state, a3 time-saving state, etc.) with different normal power opening times and normal power opening counts corresponding to the normal symbol jackpot result (normal symbol jackpot symbol). Furthermore, the condition for ending the time-saving state (normal electric support state) is, for example, that the special symbol variation display game or the normal symbol variation display game is executed a predetermined number of times (number of time-saving rounds, number of electric support rounds) while in the time-saving state. Note that a time-saving state in which the time-saving condition can be defined by the number of times the normal symbol variation display game is executed may be called the normal symbol ST state. 【0140】 After the time-saving state ends, it is possible to enter a remaining reserve consumption state (remaining reserve state) in which the second start memory (special figure 2 start memory, special figure 2 reserve) remaining at the time the time-saving state ends is consumed. In the remaining reserve consumption state (remaining reserve consumption mode, remaining reserve mode), the second start memory generated by winning into the normal variation winning device 37 (normal electric) during the time-saving state is consumed as a remaining reserve, and the special figure 2 variation display game is executed. The remaining reserve consumption state is advantageous to the player because the special figure 2 variation display game is executed. Generally speaking, the special figure 2 variation display game is more advantageous to the player than the special figure 1 variation display game in terms of the number of rounds during a big win and the probability of a small win occurring (and thus the probability of a V-winning big win). 【0141】 To explain in more detail below, the control processing by the game microcomputer 111 of the game control device 100 consists of a main process (main program) that starts when the power is turned on, and a timer interrupt process (interrupt processing program) that is performed at predetermined time intervals (for example, 4 msec). 【0142】 For example, the game control device 100 checks for abnormalities in RAM 111c during main processing, and if RAM 111c is abnormal, it prohibits access to RAM 111c and prevents gameplay unless the RAM clear switch 112 is on. For example, an abnormality in RAM 111c can be determined by whether the checksum stored in RAM 111c when the power is cut off (during a power outage) matches the checksum at the time of power-on. When RAM 111c is normal, the device transitions to various states (modes) depending on the on / off state of the RAM clear switch 112 at the time of power-on. 【0143】 In the main process, a loop is provided to allow repeated interrupts. While interrupts are allowed, the timer interrupt process is executed. During the loop, performance information such as the payout rate (base value) may be repeatedly updated as information to be displayed on the performance display device 152 (it may also be necessary to disable interrupts before updating in order to stabilize the payout rate). 【0144】 In the timer interrupt processing, the following can be executed: input processing which takes input from various switches via the input unit 120; output processing which takes various outputs via the output unit 130; special symbol game processing which controls the special symbol variation display game and sets the display of special symbols on the unified display device 50; normal symbol game processing which controls the normal symbol variation display game and sets the display of normal symbols on the unified display device 50; and error monitoring processing which monitors for errors such as fraud and abnormalities based on signals input from the fraud / abnormality sensor 67. 【0145】 Furthermore, in the timer interrupt processing, when a game ball enters the starting prize slot 36 (first starting slot) or the normal variable prize slot 37 (second starting slot) and a starting memory is generated, a pre-determination (pre-reading determination) is performed that allows for the determination of the game result based on the prize entry in advance, before the start of the special variable display game based on the starting memory. The game control device 100 is configured as a pre-determination means (pre-reading determination means) that allows for the determination of the result of the variable display game in advance, before the variable display game based on the starting memory is executed. 【0146】 Furthermore, the timer interrupt processing can execute safety device-related processing, which performs processing related to the safety device (complete function), and ball counting processing, which updates the counter that counts the number of balls. In the safety device-related processing, safety device-related information, such as the operating status of the safety device, is sent as a command to the performance control device 300, and a safety device operating flag is set to indicate that the safety device is operating. 【0147】 In the main processing initiated when the power is turned on, the game control device 100 can send power recovery commands to the performance control device 300, indicating that the power has been restored or turned on, and RAM initialization-related commands related to RAM initialization. The RAM initialization-related commands include RAM initialization commands indicating that RAM is being cleared (initialized) and RAM clear preparation commands indicating that RAM clear preparation is underway. 【0148】 Furthermore, the game control device 100 can send commands to the performance control device 300 in the timer interrupt processing as follows. 【0149】 The game control device 100 can transmit game state commands that indicate game states such as normal game state, time-saving state (normal power support state), and special feature high probability state (probability change state), error commands that indicate errors such as fraud or abnormalities, and safety device-related commands related to safety devices. Safety device-related commands include ball difference information commands that indicate the number of balls difference, operation notification commands that correspond to the operation notification state of the safety device, operation warning commands that correspond to the operation warning state of the safety device, and operation in progress commands that correspond to the operation state of the safety device. 【0150】 The game control device 100 can transmit customer waiting commands related to the customer waiting state when no game is being played, variation commands indicating the variation pattern of the special symbol variation display game, decorative stop symbol commands (decorative special symbol commands) indicating decorative stop symbols displayed on the display device 41 corresponding to losing symbols, jackpot symbols, minor jackpot symbols, time-saving symbols, etc. as a result of the special symbol variation display game, symbol stop commands indicating the stop of the special symbol variation display game, and win commands corresponding to each stage of the jackpot state or minor jackpot state. Here, customer waiting commands include customer waiting demo commands that instruct customer waiting demos such as movie demos on the demo screen. In addition, win commands include opening commands (fanfare commands) corresponding to the opening (fanfare) of a minor jackpot or jackpot, round commands corresponding to the rounds of a minor jackpot or jackpot, interval commands corresponding to the interval between rounds, and ending commands corresponding to the ending of a jackpot or minor jackpot. 【0151】 The game control device 100 can transmit a Special Feature 1 Reserve Count command and a Special Feature 2 Reserve Count command indicating the change in the number of first start memories (Special Feature 1 Reserve), which is the number of first start memories (Special Feature 1 Reserve), and the number of second start memories (Special Feature 2 Reserve), which is the number of second start memories (Special Feature 2 Reserve). The game control device 100 can also transmit a Normal Feature Reserve Count command indicating the normal start memories when the number of normal start memories (Normal Feature Reserve), which is the number of normal start memories, changes. Furthermore, the game control device 100 can increase the number of first start memories by 1 when a game ball enters the start prize entry port 36 and a first start memory is generated, and can increase the number of second start memories by 1 when a game ball enters the normal variation prize entry device 37 and a second start memory is generated. Furthermore, the game control device 100 can reduce the number of first start memories by 1 at the start of a special figure 1 variation display game based on the first start memory, and can reduce the number of second start memories by 1 at the start of a special figure 2 variation display game based on the second start memory. 【0152】 Furthermore, the game control device 100 can send a pre-read command when a game ball enters the start entry port 36 (first start port) or the normal variation entry device 37 (second start port) and a first start memory or second start memory is generated. The pre-read commands include a pre-read stop symbol command that corresponds to stop symbol information (jackpot stop symbol, minor win stop symbol, time-saving stop symbol, losing stop symbol) based on the jackpot random value or special symbol random value saved as the first start memory or second start memory, and a pre-read variation pattern command based on the saved variation pattern random value. 【0153】 In addition, the game control device 100 can transmit necessary commands to the performance control device 300, such as shooting instruction notification commands (left-shooting instruction notification commands, right-shooting instruction notification commands) that instruct (suggest) the player a recommended shooting method (shooting method) according to the game state or a change in the game state, and a specific area passage command that indicates a V-win. 【0154】 The performance control device 300 performs processing in response to commands received from the game control device 100, for example, as follows: 【0155】 When the performance control device 300 receives a power outage recovery command, it displays text such as "Recovering" on the display device 41. When it receives a RAM initialization command, it displays text such as "Clearing RAM" on the display device 41 and also provides notification by illuminating the performance LED 46 and sounding the speakers 19a and 19b for, for example, 30 seconds (especially when clearing RAM). When the performance control device 300 receives a RAM clear preparation command, it displays text such as "Preparing RAM clear" on the display device 41. 【0156】 When the performance control device 300 receives an error command, it may display text such as "Error occurring" on the display device 41, and may also provide error notification by illuminating the performance LED 46 and sounding the speakers 19a and 19b depending on the type of error command. If the error command contains information indicating the nature of the error, the display device 41 may also display the nature of the error. 【0157】 When the performance control device 300 receives a ball difference information command, it may display the number of balls on the display device 41. When the performance control device 300 receives an operation notification command, an operation warning command, or an operation command, it displays text on the display device 41 corresponding to each command, such as "Stopping soon," "Stopping after the win ends," or "Stopping." 【0158】 When the performance control device 300 receives a customer-waiting demo command while in customer-waiting state, it displays a customer-waiting demo such as a movie demo (video) on the display device 41. The customer-waiting state is entered when both the first start memory count and the second start memory count are zero and the special symbol variation display game is not being executed. The customer-waiting demo may start after a predetermined time has elapsed from the start of the customer-waiting state. 【0159】 When the performance control device 300 receives a variation command indicating a variation pattern and a decorative stop symbol command indicating a decorative stop symbol on the display device 41, it executes a variation-related performance setting process to set the performance related to the decorative special symbol variation display game on the display device 41 based on the content of the variation pattern, the type of special symbol (special symbol 1 or special symbol 2), the type of stop symbol (miss symbol, jackpot symbol, minor jackpot symbol, time-saving symbol, etc.). Furthermore, when a game ball enters the start prize entry 36 or the normal variation prize entry device 37 while the player is waiting, or when the first start memory or second start memory remains after the special symbol variation display game has ended, the game control device 100 starts the special symbol variation display game on the special symbol 1 display 51 or special symbol 2 display 52 of the all-in-one display device 50, and transmits the variation command and decorative stop symbol command to the performance control device 300. 【0160】 In the variation-related effect setting process, it is possible to set pre-announcement effects that appear during the special symbol variation display game and can foreshadow the result of the special symbol variation display game, variation effects such as pseudo-continuous effects and reach effects on the display device 41, and specific decorative stop symbols. The variation command may include information on the number of pseudo-continuous effects (number of pseudo-variations) and information on the type of reach effect corresponding to the reach state. A pseudo-continuous effect is an effect in which a predetermined number of pseudo-variations are performed on the display device 41, in which decorative special symbols are varied and temporarily stopped. In addition, in the variation-related effect setting process, it is possible to set the lighting pattern of the effect LED 46 and the sound pattern of speakers 19a and 19b according to the pre-announcement effect and variation effect. 【0161】 Here, "reach" (reach state) refers to a display state in the display device 41 where, at a stage in which part of the display result of the decorative special symbol variation display game has not yet been derived and displayed, the display result that has already been derived and displayed satisfies the conditions for becoming a special result pattern. Furthermore, when the display result becomes a special result pattern on the active line of the display device 41 (for example, on the vertical or horizontal line), the game state becomes a special game state that is advantageous to the player. In addition, a state in which variation displays are performed by multiple variation display areas while maintaining a state in which special result patterns are aligned (so-called full rotation reach) is also included in the reach state. 【0162】 Therefore, for example, if a decorative special feature variation display game displayed on the display device 41 in response to a special feature variation display game displays multiple identification information for a predetermined time in each of the left, center, and right variation display areas of the display device, and then stops the variation display in the order of left, right, center, etc., to display the result pattern, then the state in which the variation display stops in the left and right variation display areas while the conditions for a special result pattern are met (for example, the same identification information) becomes a reach state. 【0163】 Furthermore, multiple reach animations can be performed during a reach state, and there are different types of reach animations with varying probabilities (reliability) of leading to special outcome modes (jackpot modes and minor win modes). For example, there are Normal Reach (N Reach), Special 1 Reach (SP1 Reach), Special 2 Reach (SP2 Reach), Special 3 Reach (SP3 Reach), and Premium Reach. The probability (reliability) of winning a jackpot increases in the following order: No Reach < Normal Reach < Special 1 Reach < Special 2 Reach < Special 3 Reach < Premium Reach. Also, a reach state is a state where the probability of winning a jackpot is higher than when a reach state does not occur. 【0164】 The expected value (reliability) of a special effect (preview) indicates the probability of a big win if that effect is selected, and can be calculated based on the selection rate of that effect when a big win occurs and the selection rate of that effect when a loss occurs. The higher the selection rate of that effect when a big win occurs, the higher the expected value, and the higher the selection rate of that effect when a loss occurs, the lower the expected value. Big wins include the aforementioned V-entry big wins, and the expected value for V-entry big wins is approximately the same as the expected value for minor wins that result in V-entry. In addition to the expected value for big wins, the expected value for other advantageous states (e.g., minor win state, time-saving state) and advantageous events (e.g., reach) can also be set in the same way. 【0165】 When the performance control device 300 receives a symbol stop command indicating the stop of the special symbol variation display game, it sets the display device 41 to stop the decorative special symbol variation display game. Alternatively, the game control device 100 can send a variation time command indicating the value of the variation time to the performance control device 300, and the performance control device 300 can set the decorative special symbol variation display game to stop after the variation time has elapsed from the start of the decorative special symbol variation display game. 【0166】 When the performance control device 300 receives an opening command, it executes an opening performance (fanfare performance), which is the start performance of a minor or major win. When it receives a round command, it executes a round performance, which is the performance during a round. When it receives an interval command, it executes an interval performance during the interval between rounds. When it receives an ending command, it executes an ending performance corresponding to the ending of a major or minor win. 【0167】 When the performance control device 300 receives a Special Symbol 1 Reserve Count command or a Special Symbol 2 Reserve Count command, it displays the same number of reserve indicators corresponding to the Special Symbol Start Memory (Special Symbol Reserve) on the display device 41 or the like. Alternatively, when the performance control device 300 receives a Normal Symbol Reserve Count command, it may also display the same number of reserve indicators corresponding to the Normal Symbol Start Memory (Normal Symbol Reserve) on the display device 41 or the like. When the performance control device 300 receives a Pre-read Variation Pattern command and a Pre-read Stop Symbol command as pre-read commands, it draws and sets a pre-read notification performance (pre-read performance, pre-read notification) with a lottery probability corresponding to the pre-read command. Examples of pre-read notification performances include consecutive notification performances and reserve change notifications. Examples of consecutive notification performances include chance symbol pre-read performances related to decorative stop symbols. The pending change notification indicates that the display method of the pending display (color, shape, pattern, effect, etc.) changes from the normal one, suggesting that the probability of the variable display game based on the pending display being a win is higher than when the pending display does not change (normal). 【0168】 When the performance control device 300 receives a left-hit instruction notification command and a right-hit instruction notification command as hitting instruction notification commands, it can execute a left-hit instruction display and a right-hit instruction display on the display device 41 corresponding to each command. When the performance control device 300 receives a specific area passing command, it may execute a performance on the display device 41 that celebrates a V-win. 【0169】 Furthermore, the performance control device 300 is also capable of receiving commands necessary for control from the game control device 100, in addition to those mentioned above. 【0170】 [Back of the gaming machine] Next, referring to Figure 5, the configuration of the game control device 100 (control device, main board, game control board, etc.) located on the back side of the game machine 10 will be described. Figure 5 is a rear view of the game machine 10. 【0171】 On the back of the gaming machine 10, a gaming control device 100, a frame control device 200, a performance control device 300 (sub-board), and a power supply device 400 are installed. 【0172】 The game control device 100 controls the game (play) and can transmit performance control commands to the performance control device 300, which in turn controls the display device 41 and other devices based on these performance control commands. The frame control device 200 counts the game medium (game balls), which represent the game value circulating within the enclosed game machine 10 (smart pachinko machine), based on the data transmitted from the game control device 100. The power supply device 400 supplies power to the various devices. 【0173】 Furthermore, the game control device 100 is equipped with a setting key switch 93 and a RAM clear switch 112. The setting key switch 93 and the RAM clear switch 112 are located on the game control device 100 inside the game machine 10, in a position that cannot be operated (inaccessible) unless the front frame 12 (main frame) is opened. In other words, ordinary players cannot access and operate the setting key switch 93 and the RAM clear switch 112. The setting key switch 93 and the RAM clear switch 112 are located on the back side of the game machine 10, so they are not hidden (overlapped) by the operation of internal or external components attached to the game machine 10. 【0174】 When the power is turned on, the RAM clear switch 112 is pressed and turned on, which initiates the RAM initialization process. During the RAM initialization process, the information stored in the RAM 111c in the game microcontroller 111 and the RAM in the frame control device 200 is forcibly initialized (reset), and if an error has occurred, that error is also reset (cleared). In this way, the RAM clear switch can also function as an error clearing switch. Furthermore, the RAM clear switch 112 can also be used as a setting value change switch that allows the probability setting value (setting value) to be changed according to the operator's operation. 【0175】 The setting key switch 93, when turned on by the operator's rotation or other operation, enables or allows the change of probability setting values ​​according to the game conditions (game) settings. In this embodiment, the probability setting value is a setting value for setting winning probabilities such as the probability of a big win or the probability of a small win, but other game conditions (such as effects) can also be changed according to the probability setting value. For example, the larger the probability setting value, the larger the winning probability may be. The setting key switch 93 and the RAM clear switch 112 constitute a setting change means (setting change device 42, setting means) that can change the settings (probability setting value) related to the game conditions. Note that another switch may also serve as a setting value change switch or an error clear switch instead of the RAM clear switch 112, or dedicated setting value change switches or error clear switches may be provided. 【0176】 When the gaming machine 10 is powered on (after a power outage, power is restored), the gaming machine 10 can transition to various states depending on the on / off state of the setting key switch 93 and the RAM clear switch 112. These states include a variable setting state (setting change state, configurable state, setting change mode, setting mode) where the probability setting value can be changed (configured), and a setting confirmation state (setting confirmation mode, confirmation mode) where the probability setting value can be checked. For example, when the power is turned on, if both the setting key switch 93 and the RAM clear switch 112 are on, the machine transitions to the variable setting state, and if only the setting key switch 93 is on, it transitions to the setting confirmation state. Also, if only the RAM clear switch 112 is on, the RAM initialization process is executed, and if both the setting key switch 93 and the RAM clear switch 112 are off, the machine transitions to a playable state. 【0177】 [Game control device] Next, with reference to Figures 6 to 8, the game control device 100 (control device, main board, game control board) located on the back side of the game machine 10 will be described. 【0178】 Figure 6 is a front view of the game control device 100. Figure 7 is a perspective view of the game control device 100, and Figure 8 is a perspective view of a part of the game control device 100 that has been disassembled. Note that Figure 6 shows the front of the game control device 100 as seen from, for example, the back of the game machine 10. 【0179】 The game control device 100 includes a circuit board 110 (see Figure 3) on which a game microcomputer 111, an input unit 120, and an output unit 130 are mounted, a case 140 for housing the circuit board 110, and a base body 143 (see Figures 7 and 8) for attaching the circuit board 110 housed in the case 140 to the game machine 1. The circuit board 110 is provided with terminals (pins) for connecting the game control device 100 to an external device (equipment). Specifically, as shown in Figure 6, the circuit board 110 is provided with connectors CN1 to CN5 having one or more pins. The circuit board 110 may also have connectors that transmit optical signals without pins or transmit radio waves non-contact using dedicated contacts or antennas. 【0180】 For example, connector CN1 is used to detect signals when a game ball enters a prize slot, such as the starting gate 34. Connector CN2 is used to transmit game-related commands to the performance control device 300. Connector CN3 is connected to the power supply device 400 and the frame control device 200 to supply power and is used for inputting signals such as power outage monitoring signals and reset signals, as well as sending and receiving commands related to payouts. Connector CN4 is connected to an external information collection device or management device and is used to output game data. Connector CN5 is connected to an external inspection device and is used to output inspection signals. 【0181】 As shown in Figures 6 to 8, the case 140 comprises a first case member 141 for housing the substrate member 110, and a second case member 142 as a lid that defines a section for housing the substrate member 110 between itself and the first case member 141. 【0182】 As shown in Figure 6, the second case member 142 has openings 142a to 142e that expose connectors CN1 to CN5 to the outside. Additionally, the second case member 142 may be provided with openings that expose the setting key switch 93 and the RAM clear switch 112 to the outside. 【0183】 The case 140 has a crimping portion A 140a, a crimping portion B 140b, a crimping portion C 140c, and a crimping portion F 140f. The crimping portion A 140a is used when sealing (enclosing) the substrate member 110 in the case 140. 【0184】 Crimping section B 140b is used when fixing (installing) the case 140 to the back of the gaming machine 10 (main body). Crimping section C 140c is used during on-site inspections. Crimping section F 140f is used when recovering the circuit board member 110. As shown in Figure 7, a base body 143 for fixing the case 140 to the back of the gaming machine 10 is attached to crimping section C 140c and crimping section B 140b. 【0185】 As shown in Figures 7 and 8, the base body 143 has a lever portion 143a that engages with the crimping portion C 140c. Therefore, when the base body 143 is attached to the crimping portion B 140b, the base body 143 also engages with the crimping portion C 140c by the lever portion 143a, making it easier to securely fix the case 140 to the base body 143. 【0186】 Furthermore, as shown in Figure 8, a case crimping hook 144a can be inserted into the crimping portion 140a of section A, and a main body crimping hook 144b can be inserted into the crimping portion 140b of section B. A main body crimping hook 144c can be inserted into the crimping portion 140c of section C and the base body 143, and a case crimping hook 144f can be inserted into the crimping portion 140f of section F. Although the case crimping hooks 144a, 144f and the main body crimping hooks 144b, 144c have different shapes, two or more components may be made to have the same shape and used as common components. 【0187】 For example, at the time of factory shipment, a case crimping hook 144a is inserted into and crimped into the crimping portion A 140a, and a body crimping hook 144b is inserted into and crimped into the crimping portion B 140b and the base body 143. As shown in Figure 8, the case crimping hook 144a is a separate component from the case 140, and the body crimping hook 144b is a separate component from the case 140 and the base body 143. In this way, once the case 140 is crimped and sealed, it is necessary to detach (cut) the crimping portion A 140a and the crimping portion B 140b in order to remove the substrate member 110. Therefore, detaching the crimping portion A 140a and the crimping portion B 140b leaves traces, making it easy to detect any fraudulent activity, such as the replacement of the substrate member 110. 【0188】 Furthermore, for example, after being opened during an inspection, the case 140 is resealed by inserting the main crimping hook 144c into the crimping portion C 140c and crimping it. For example, after being opened when the substrate member 110 is recovered, the case 140 is resealed by inserting the case crimping hook 144f into the crimping portion F 140f and crimping it. As shown in Figure 8, the main crimping hook 144c is a separate component from the case 140 and the base body 143, and the case crimping hook 144f is a separate component from the case 140. 【0189】 [Around the connector of the gaming control device] Next, with reference to Figures 9 to 10, the configuration around the connector CN1 of the circuit board component 110 of the game control device 100 will be described. 【0190】 Figure 9 is a magnified front view of a part of the game control device 100 (around connector CN1) with the case 140 in place. Figure 10 is a magnified front view of a part of the game control device 100 (around connector CN1) without the case 140. 【0191】 As shown in Figure 9, the connector CN1 is exposed perpendicular to the surface of the substrate member 110 through the opening 142a of the case 140. On the substrate member 110, character information 110a, 110b, 110c, 110d, and 110e are printed or otherwise attached as first character information representing information about the connector CN1, in the vicinity of the outside of the connector CN1. 【0192】 The character information 110a, 110b, 110c, and 110d represent information about the pin positions of connector CN1, as shown in Figures 9 and 10 (see Figure 10 in particular). For example, character information 110a displays "1" near pin 1. Character information 110b displays "2" near pin 2, character information 110c displays "9" near pin 9, and character information 110d displays "10" near pin 10. Therefore, when the circuit board member 110 is not housed in the case 140 as shown in Figure 10, the worker can easily align the orientation of connector CN1 with respect to the circuit board member 110 by checking these character information 110a, 110b, 110c, and 110d, thereby improving the workability when installing the connector on the circuit board member 110. 【0193】 The character information 110e represents the name of the connector CN1 on the substrate component 110, and is displayed as, for example, "CN1". 【0194】 Furthermore, the character information 110d represents the largest (maximum) pin number of connector CN1 (for example, "10"), allowing the operator to easily recognize that connector CN1 is a 10-pin connector by visually inspecting the character information 110d. 【0195】 As shown in Figure 9, when the substrate member 110 is housed in the case 140, the character information 110a, 110b, 110c, 110d, and 110e overlap with the case 140 in a vertical direction, resulting in poor visibility. At least a portion of the character information 110a, 110b, 110c, 110d, and 110e overlaps with the edge of the opening 142a, as shown in Figure 9, and the visibility of the area overlapping with the case 140 from that edge is poor. Therefore, when the substrate member 110 is housed in the case 140, it becomes difficult to read information about connector CN1 from the character information 110a, 110b, 110c, 110d, and 110e, making it easier to prevent fraudulent activity. 【0196】 As shown in Figures 9 and 10, the inside of connector CN1 has character information CN1a, CN1b, and CN1c molded as second-character information representing information about connector CN1. Note that character information CN1a, CN1b, and CN1c may also be attached to the inside of connector CN1 by printing or engraving. 【0197】 The character information CN1a, for example, displays "1" near pin 1. By including the number "1" corresponding to pin 1 in the character information CN1a, it becomes easier for the operator to confirm the location of pin 1. 【0198】 The character information CN1b displays characters (for example, "GNPT") that include the serial number, lot number, specifications, model number, name, manufacturer, etc., of connector CN1. 【0199】 The character information CN1c displays characters (e.g., "10GN") that include the pin number of connector CN1 (e.g., "10"). For example, as shown in Figure 9, the character information CN1c may include the highest pin number of connector CN1 (e.g., "10" indicating pin 10). The character information CN1c may also include a number (e.g., "10") corresponding to the number of pins (pin count) of connector CN1 (e.g., 10 pins), and may also include the product number (model number) or the name of connector CN1. 【0200】 When the circuit board component 110 is housed in the case 140, the text information CN1a, CN1b, and CN1c do not overlap vertically with the case 140, thus maintaining good visibility. Therefore, it is easier for the worker who connects the connector jack (not shown) as the wiring side connector to the connector CN1 after housing to confirm the text information CN1a, CN1b, and CN1c, thereby improving work efficiency. The connector jack has holes 1, 2, 9, and 10 (sockets) that can be electrically connected to external devices, and the corresponding pins 1, 2, 9, and 10 of the connector CN1 are inserted into these sockets for connection. 【0201】 Furthermore, when the connector jack is connected to connector CN1, the character information CN1a, CN1b, and CN1c are covered by the connector jack and become invisible. Therefore, after connection, it becomes impossible to read information about connector CN1 from the character information CN1a, CN1b, and CN1c, making it easier to prevent fraudulent activity. 【0202】 [Effects of the First Embodiment] In this embodiment, the gaming machine 10 includes a control device (gaming control device 100, main board, gaming control board) that controls games (symbol variation game, variation game, variation display game, special symbol variation display game). In the gaming machine 10, the control device includes a board (board member 110) and a case member (case 140) that covers the board. The board has connectors (connectors CN1 to CN5) to which wiring-side connectors (connector jacks) of wiring that can be electrically connected to the outside of the control device are connected, first character information (character information 110a, 110b, 110c, 110d, 110e) representing information about the connector (for example, connector CN1) around the connector, and second character information (character information CN1a, CN1b, CN1c) representing information about the connector (for example, connector CN1) inside the connector. The case member has openings (openings 142a to 142e) that expose the connector perpendicular to the surface of the substrate, and when the substrate is housed inside, these openings overlap with at least a portion of the first character information in that perpendicular direction. 【0203】 With this type of gaming machine 10, when the circuit board is not housed in the case, the worker can easily confirm the first character information, and by confirming this first character information, it becomes easier to correctly align the connector to the circuit board, thus improving the workability when installing the connector to the circuit board. Furthermore, when the circuit board is housed in the case, at least a portion of the first character information is obscured by the case, making it difficult to read information about the connector from the first character information, thus making it easier to prevent fraudulent activity. In this way, the gaming machine 10 can achieve both improved workability and prevention of fraudulent activity, thereby improving the quality of the gaming machine 10. 【0204】 Furthermore, in the gaming machine 10, the case member has an edge that forms an opening, and when the circuit board is housed, this edge overlaps with at least a portion of the first character information. With such a gaming machine 10, at least a portion of the first character information overlaps with the edge of the opening, making it difficult to read the connector information from the first character information, thus making it easier to prevent fraudulent activity. 【0205】 Furthermore, the gaming machine 10 includes a control device (gaming control device 100, main board, gaming control board) that controls games (symbol variation game, variation game, variation display game, special symbol variation display game). In the gaming machine 10, the control device includes a board (board member 110) and a case member (case 140) that covers the board. The board has connectors (connectors CN1 to CN5) to which wiring-side connectors (connector jacks) of wiring that can be electrically connected to the outside of the control device are connected, first character information (character information 110a, 110b, 110c, 110d, 110e) representing information about the connector (for example, connector CN1) around the connector, and second character information (character information CN1a, CN1b, CN1c) representing information about the connector (for example, connector CN1) inside the connector. The case member has openings (openings 142a to 142e) that expose the connector perpendicular to the surface of the substrate, and when the substrate is housed, these openings overlap with at least a portion of the first character information in the perpendicular direction, and the first character information includes the same characters as at least a portion of the second character information. 【0206】 With this type of gaming machine 10, when the circuit board is not housed in the case, the first character information, which contains at least some of the same characters as the second character information, becomes easier to verify together with the second character information. Therefore, by verifying the first character information and the second character information, it becomes easier to correctly align the connector corresponding to the circuit board and the orientation of the connector relative to the circuit board, thereby improving the workability when installing the connector on the circuit board. Furthermore, when the circuit board is housed in the case, at least some of the first character information overlaps with the case, reducing its visibility and making it difficult to read connector information from the first character information, thus making it easier to prevent fraudulent activity. 【0207】 Furthermore, the gaming machine 10 includes a control device (gaming control device 100, main board, gaming control board) that controls games (symbol variation game, variation game, variation display game, special symbol variation display game). In the gaming machine 10, the control device includes a board (board member 110) and a case member (case 140) that covers the board. The board has connectors (connectors CN1 to CN5) to which wiring-side connectors (connector jacks) of wiring that can be electrically connected to the outside of the control device are connected, first character information (character information 110a, 110b, 110c, 110d, 110e) representing information about the connector (for example, connector CN1) around the connector, and second character information (character information CN1a, CN1b, CN1c) representing information about the connector (for example, connector CN1) inside the connector. The case member has openings (openings 142a to 142e) that expose the connector perpendicular to the surface of the substrate, and when the substrate is housed, it overlaps with at least a portion of the first character information in that perpendicular direction, the connector has pins, and the second character information includes the pin numbers. 【0208】 With this type of gaming machine 10, when the circuit board is not housed in the case, the worker can easily see the first character information, and by seeing this first character information and matching it with the pin number in the second character information, it becomes easier to correctly align the connector to the circuit board. As a result, the workability when installing the connector to the circuit board can be further improved. Furthermore, when the circuit board is housed in the case, at least a portion of the first character information is obscured by the case, and when the wiring side connector is connected to the connector, the second character information, including the pin number, becomes invisible. Therefore, it becomes difficult to read information about the connector from the first and second character information, making it easier to prevent fraudulent activity. 【0209】 Furthermore, the gaming machine 10 includes a control device (gaming control device 100, main board, gaming control board) that controls games (symbol variation game, variation game, variation display game, special symbol variation display game). In the gaming machine 10, the control device includes a board (board member 110) and a case member (case 140) that covers the board. The board has connectors (connectors CN1 to CN5) to which wiring-side connectors (connector jacks) of wiring that can be electrically connected to the outside of the control device are connected, first character information (character information 110a, 110b, 110c, 110d, 110e) representing information about the connector (for example, connector CN1) around the connector, and second character information (character information CN1a, CN1b, CN1c) representing information about the connector (for example, connector CN1) inside the connector. The case member has openings (openings 142a to 142e) that expose the connector perpendicular to the surface of the substrate, and when the substrate is housed, at least a portion of the first character information overlaps in this perpendicular direction, and the second character information includes the name of the connector. 【0210】 With this type of gaming machine 10, when the circuit board is not housed in the case, the worker can easily see the first character information, and by seeing this first character information and matching it with the connector name in the second character information, it becomes easier to correctly attach the connector corresponding to the circuit board, thus improving the work efficiency when installing connectors on the circuit board. Furthermore, when the circuit board is housed in the case, at least a portion of the first character information is obscured by the case, and when the wiring-side connector is connected to the connector, the second character information, including the name of the connector, becomes invisible. Therefore, it becomes difficult to read information about the connector from the first and second character information, making it easier to prevent fraudulent activity. In addition, before the wiring-side connector is connected to the connector, the worker can easily see the second character information, including the name of the connector, thus improving the work efficiency when connecting the wiring-side connector. 【0211】 Furthermore, the gaming machine 10 includes a control device (gaming control device 100, main board, gaming control board) that controls games (symbol variation game, variation game, variation display game, special symbol variation display game). In the gaming machine 10, the control device includes a board (board member 110) and a case member (case 140) that covers the board. The board has connectors (connectors CN1 to CN5) to which wiring-side connectors (connector jacks) of wiring that can be electrically connected to the outside of the control device are connected, first character information (character information 110a, 110b, 110c, 110d, 110e) representing information about the connector (for example, connector CN1) around the connector, and second character information (character information CN1a, CN1b, CN1c) representing information about the connector (for example, connector CN1) inside the connector. The case member has openings (openings 142a to 142e) that expose the connector perpendicular to the surface of the substrate, and when the substrate is housed, it overlaps with at least a portion of the first character information in the perpendicular direction, but the case member does not overlap with the second character information. 【0212】 With this type of gaming machine 10, when the circuit board is not housed in the case, the worker can easily confirm the first character information, and by confirming this first character information, it becomes easier to correctly align the connector to the circuit board, thus improving the work efficiency when installing the connector to the circuit board. Furthermore, when the circuit board is housed in the case, at least a portion of the first character information is obscured by the case, making it difficult to read information about the connector from the first character information, thus making it easier to prevent fraudulent activity. Also, since the case does not overlap with the second character information, the worker can easily confirm the second character information when connecting the wiring-side connector to the connector, improving the work efficiency when connecting the wiring-side connector. After the wiring-side connector is connected, the second character information is obscured by the wiring-side connector, making it difficult to read information about the connector from the second character information, thus making it easier to prevent fraudulent activity. 【0213】 [Second Embodiment] The second embodiment of the gaming machine 10 will be described with reference to Figures 11 to 20. Note that configurations other than those described below may be the same as those in the first embodiment. Furthermore, in the following embodiments, the same reference numerals are used for components that perform the same functions as in the first embodiment, and redundant descriptions will be omitted as appropriate. 【0214】 In the second embodiment, the configuration of the circuit board members 110 and case 140 of the game control device 100 (main board) will be mainly described. 【0215】 [Back of the gaming machine] Figure 11 is a rear view of the gaming machine according to the second embodiment. 【0216】 When the game control device 100 is installed on the back of the game machine 10, the circuit board component 110 of the game control device 100 is housed in a case 140. Various connectors (e.g., connectors CN2 and CN5) of the circuit board component 110 are exposed through an opening in the case 140. Connector CN2 functions as a specific internal connector that can be connected to a specific internal device of the game machine 10 (e.g., the performance control device 300). Connector CN5 functions as a test connector for testing purposes. Note that in Figure 11, the game control device 100 is shown in a simplified manner and some connectors are omitted from the illustration, but as shown in Figures 12-13, other connectors are also exposed through the opening in the case 140. 【0217】 Furthermore, the circuit board component 310 of the performance control device 300 is also housed in the case 340, and various connectors of the circuit board component 310 (for example, connector CN31) are exposed through an opening in the case 340. Similarly, the unit control device 220 of the frame control device 200 is also housed in the case 230. Note that connectors of the circuit board component 310 and the unit control device 220 (not shown) may be exposed from the cases 340 and 230. 【0218】 [Game control device] Next, with reference to Figures 12 to 14, the game control device 100 (control device, main board, game control board) located on the back side of the game machine 10 will be described. 【0219】 Figure 12 is a perspective view of the game control device 100 according to the second embodiment. Figure 13 is a front view of the game control device 100 according to the second embodiment, and Figure 14 is a front view of the circuit board member 110 of the game control device 100 according to the second embodiment. 【0220】 As shown in Figures 12 and 13, multiple (for example, three) seals 145a to 145c are attached to the surface of the second case member 142 of the case 140 of the second embodiment. 【0221】 The seal 145a has a two-dimensional code 145a1 for the case and character information 145a2 that represent information such as the model number of the substrate component 110. The two-dimensional code 145a1 can be read by a two-dimensional code reader (camera) to display the information of the substrate component 110 on the two-dimensional code reader or the like. The character information 145a2 can consist of multiple lines (for example, 3 lines) of characters (for example, alphanumeric characters "00000, 000 12, 000 34"). 【0222】 Seal 145b, like seal 145a, has a two-dimensional code 145b1 for the case and character information 145b2 that represent information about the substrate material 110. The character information 145b2 can consist of multiple lines (e.g., three lines) of characters (e.g., alphanumeric characters "AAAAA, AA 12, AA 34"). Note that the character information 145a2 and 145b2 may use Japanese characters or other languages, not just alphanumeric characters. 【0223】 The seal 145c has a two-dimensional code 145c1 for the case that represents information about the substrate member 110. 【0224】 The two-dimensional codes 145a1, 145b1, and 145c1 are the same size and are located at approximately the same height from the surface of the substrate material 110 on the surface of the case 140. Because the two-dimensional codes 145a1, 145b1, and 145c1 on the same plane are the same size, the two-dimensional codes 145a1, 145b1, and 145c1 can be read in the same way at approximately a constant distance from the surface of the case 140 without having to move the position of the two-dimensional code reader back and forth to adjust the focus, making it easier to confirm the information on the substrate material 110. In addition, the two-dimensional codes 145a1, 145b1, and 145c1 are located on the surface of the case 140 in the same orientation. Therefore, it is easy to confirm that the two-dimensional codes 145a1, 145b1, and 145c1 are the same code. 【0225】 Furthermore, as shown in Figure 13, when the substrate member 110 is housed in the case 140, the first side wall portion 142f1 and the second side wall portion 142f2 of the second case member 142 are located between the connector CN2, which is a specific internal connector, and the connector CN5, which is a test connector. The first side wall portion 142f1 and the second side wall portion 142f2 are part of the surface that forms the side of the second case member 142, and are side wall portions that extend at an angle (for example, perpendicularly) in the direction rising from the surface of the substrate member 110. The area between connector CN2 and connector CN5 is, for example, the area inside the dashed line (dummy line) connecting the corners of both connectors, as shown in Figures 13 and 14. 【0226】 In this case, when the device is not connected to an external testing terminal, damage to connector CN5 is unlikely to affect the game, making it possible for tampering to start from connector CN5. However, when attempting to tamper with connector CN2 from connector CN5, it is necessary to damage both side walls (first side wall 142f1, second side wall 142f2) of the second case member 142 in order to access connector CN2, thus making it easier to prevent tampering. 【0227】 Furthermore, as shown in Figure 13, the seal 145b is attached between connector CN2 and connector CN5 (the area inside the dashed line), making it difficult to see inside and thus making it harder for tampering to occur. 【0228】 Next, as shown in Figure 14, the circuit board member 110 has multiple components (electronic components) such as ROM 111d, RAM 111e, resistor 111f, and chip resistor 111g, in addition to the gaming microcontroller 111 and connectors CN1 to CN5 described above in the first embodiment. The gaming microcontroller 111 has ROM 111b and RAM 111c built in, but as shown in Figure 14, ROM 111d and RAM 111e can also be separately provided (added) on the circuit board member 110 as one of multiple components. Furthermore, the gaming microcontroller 111, ROM 111b, and RAM 111c are not located between connector CN2 and connector CN5. Therefore, when an attempt is made to tamper with connector CN5 from the connector CN2 side, the distance to the gaming microcontroller 111, etc. becomes greater, making it easier to prevent tampering with the gaming microcontroller 111, etc. in conjunction with tampering with connector CN5. 【0229】 Multiple resistors 111f are arranged in a multi-way configuration between connectors CN2 and CN5. Similarly, chip resistors 111g are plate-shaped electronic components and are also arranged in a multi-way configuration between connectors CN2 and CN5. Therefore, even if the side wall of connector CN5 is damaged, the resistors 111f and chip resistors 111g are located in a position to interfere with each other between connectors CN2 and CN5. This makes it easier to damage these components along with the side wall, thus preventing the device from operating under tampered conditions. 【0230】 A two-dimensional code 113a, representing information about the gaming microcontroller 111, is affixed as a sticker to the surface of the gaming microcontroller 111. In addition, text information representing information about the gaming microcontroller 111, such as "CPUab12", is printed on the surface of the gaming microcontroller 111. Here, the orientation of the two-dimensional code 113a is upside down, as illustrated in reverse in Figure 14, and differs from the orientation of the text information ("CPUab12") (facing forward in Figure 14). In this way, the orientation of the two-dimensional code 113a and the text information ("CPUab12") are different, so if they become the same orientation, it is easy to recognize that there is a high probability that an unauthorized component has been installed. 【0231】 Furthermore, a two-dimensional code 113b for components representing the information of ROM111d is affixed as a sticker to the surface of ROM111d, and text information representing the information of ROM111d, such as "ROMcd34", is printed or otherwise attached. The two-dimensional code 113b and the text information ("ROMcd34") are oriented in the same direction (facing forward in Figure 14). 【0232】 Thus, while the orientation of the two-dimensional code 113a and the text information ("CPUab12") of the aforementioned gaming microcontroller 111 are deliberately made different, the presence of a component like ROM111d, which aligns the orientation of the two-dimensional code 113b and the text information ("ROMcd34"), makes it appear as if the orientation of the two-dimensional codes is randomly applied. As a result, it becomes difficult for those attempting to cheat to pay attention to the orientation of the two-dimensional codes and the text information, and when cheating occurs, the orientation is more likely to be incorrect, making it easier to detect the presence of unauthorized components. 【0233】 Furthermore, a two-dimensional code 113c for components representing information about RAM111e is affixed as a sticker to the surface of RAM111e, and text information representing information about RAM111e, such as "RAMe5," is printed on it. The text information ("RAMe5") is affixed upside down, as shown in reverse in Figure 14, and is oriented differently from the orientation of the two-dimensional code 113c (facing forward in Figure 14). Therefore, just like with the gaming microcontroller 111, if the orientation of the two-dimensional code 113c and the text information ("RAMe5") becomes the same (if they are oriented the same), it is easy to recognize that there is a high probability that an unauthorized component has been installed. In addition, since the orientation of the two-dimensional codes 113a, 113b, 113c and text information on the gaming microcontroller 111, ROM11d, and RAM111e appears to be more randomly affixed, it is difficult to make a cheater pay attention to the orientation of the two-dimensional codes and text information. 【0234】 Furthermore, two-dimensional codes 113d and 113e, which represent information about the circuit board component 110, are affixed as stickers to the surface of the circuit board component 110. Two-dimensional code 113d is affixed, for example, near connector CN5, while two-dimensional code 113e is affixed at a distance from two-dimensional code 113d. Two-dimensional codes 113d and 113e can be the same two-dimensional code. Alternatively, the same two-dimensional code may be placed on other parts of the surface of the circuit board component 110. By placing the same two-dimensional codes 113d and 113e at different distances in this way, when reading with a two-dimensional code reader, it is possible to select and read the code that is easily accessible and close, free from obstacles such as cables, thereby improving work efficiency. 【0235】 Here, the orientation of the two-dimensional code 113a of the gaming microcontroller 111 (reverse orientation in Figure 14) is different from the orientation of the two-dimensional codes 113d and e for the circuit board (facing forward in Figure 14) and the orientation of the two-dimensional codes 145a1, 145b1, and 145c1 for the case (facing forward in Figure 13). Therefore, since the orientation of the two-dimensional codes 113d and e for the circuit board and the orientation of the two-dimensional code 113a of the gaming microcontroller 111 are different, it is easy to recognize that there is a high probability that an unauthorized component has been installed if the orientations are no longer different. 【0236】 Furthermore, the two-dimensional codes 113a, 113b, and 113c for these components and the two-dimensional codes 113d and 113e for the circuit board are the same size and are all attached to components on or near the surface of the circuit board material 110. By making the two-dimensional codes on the same plane layer the same size, it is not necessary to change the position of the two-dimensional code reader for focus adjustment, thereby improving the work efficiency when reading during inspection. 【0237】 Furthermore, the two-dimensional codes 113a, 113b, 113c for these components and 113d, 113e for the circuit board are smaller than the two-dimensional codes 145a1, 145b1, 145c1 for the case 140 (see Figure 13). Therefore, when reading the two-dimensional codes 145a1, 145b1, 145c1 for the case 140, which are located on the front planar layer of the two-dimensional code reader, it is easier to prevent the two-dimensional codes 113a, 113b, 113c for the components and 113d, 113e for the circuit board, which are located on the back planar layer, from being mistakenly read, thereby improving work efficiency. Furthermore, the two-dimensional codes 113a, 113b, 113c for components and 113d, 113e for the circuit board, which are located on the rear planar layer, are smaller than the two-dimensional codes 145a1, 145b1, 145c1 for the case 140. This makes it difficult to read the circuit board material 110 if it is photographed illegally, thus making it easier to prevent the illegal acquisition of information about the circuit board material 110 and its components. 【0238】 In addition to attaching the two-dimensional code to the circuit board component 110 and case 140 of the game control device 100, the same two-dimensional code may also be appropriately attached to the frame control device 200, the performance control device 300, and the power supply device 400. Furthermore, the two-dimensional code may be attached by printing or other means, rather than being attached as a sticker. 【0239】 Furthermore, as shown in Figure 14, the substrate member 110 has conductive holes (through holes, pier holes) 114a near the edge of the substrate member 110 and conductive holes 114b near the connector CN2. The conductive holes 114a and 114b are used to electrically connect the surface pattern (not shown) and the back surface pattern (not shown) of the substrate member 110. 【0240】 [Conductive hole] Next, the conductive holes 114a and 114b of the substrate member 110 will be explained with reference to Figures 15 to 17. Figure 15 is a cross-sectional view along the line XV-XV in Figure 13. Figure 16 is a cross-sectional view (first half) explaining the relationship between the conductive hole 114b and the second side wall portion 114f2 of the substrate member 110, and Figure 17 is a cross-sectional view (second half) explaining the relationship between the conductive hole 114b and the second side wall portion 114f2 of the substrate member 110. Although Figures 16 and 17 illustrate the relationship between the conductive hole 114b and the second side wall portion 114f2, the relationship between the conductive hole 114a and the first side wall portion 114f1 can be similarly explained. In addition, conductive holes other than the conductive holes 114a and 114b may be provided in the substrate member 110 as appropriate. 【0241】 When the substrate member 110 is housed in the case 140, the conductive hole 114a is perpendicular to the surface of the substrate member 110 and overlaps with the first side wall portion 142f1 of the second case member 142. Similarly, the conductive hole 114b overlaps with the second side wall portion 142f2 of the second case member 142. Therefore, even if a hole is drilled from the top of the case 140, i.e., on the surface of the second case member 142, the conductive holes 114a and 114b overlap with the first side wall portion 142f1 and the second side wall portion 142f2 in the vertical direction, preventing the conductive holes 114a and 114b from being located directly below the hole on the surface, thus making it difficult to access the conductive holes 114a and 114b illegally. 【0242】 Furthermore, the conduction hole 114a is provided between the first side wall portion 142f1 and the ROM 111d, and the conduction hole 114b is provided between the second side wall portion 142f2 and the chip resistor 111g. The first side wall portion 142f1 and the second side wall portion 142f2 extend upward from the surface of the substrate member 110 at an angle ranging from, for example, 45 degrees to 90 degrees (perpendicular). 【0243】 As shown by the arrows in Figure 15, when viewing the inside of the case 140 perpendicular to the first side wall 142f1, the ROM 111d is positioned to overlap with the first side wall 142f1. Similarly, when viewing the inside of the case 140 perpendicular to the second side wall 142f2, the chip resistor 111g is positioned to overlap with the second side wall 142f2. In this way, the electronic components (ROM 111d and chip resistor 111g) are positioned to overlap when viewing the inside of the case 140 perpendicular to the first side wall 142f1 and the second side wall 142f2. Therefore, if the first side wall 142f1 or the second side wall 142f2 of the case 140 is destroyed, the electronic components positioned at the overlapping locations are more likely to be damaged along with it, making it easier to prevent the electronic components from operating in an unauthorized state. 【0244】 Furthermore, as described above, the first side wall portion 142f1 and the second side wall portion 142f2 and the conductive holes 114a and 114b overlap perpendicularly with respect to the surface of the substrate member 110, making it difficult to illegally access the conductive holes 114a and 114b by drilling a hole from the surface of the second case member 142. Therefore, it is more likely that someone attempting to commit fraud will break the case 140 from the side of the second case member 142, that is, from the first side wall portion 142f1 and the second side wall portion 142f2. However, if the first side wall portion 142f1 and the second side wall portion 142f2 are illegally damaged, nearby electronic components will also be more easily damaged. 【0245】 Furthermore, the second case member 142 has a recessed top to match the ROM 111d and is in close proximity to the ROM 111d. Therefore, the gap between the second case member 142 and the ROM 111d is not large, which prevents unauthorized devices from being inserted through this gap. In addition, if the second case member 142 is damaged from above, the ROM 111d is also easily damaged at the same time, making it easier to prevent the ROM 111d from operating while it has been tampered with. 【0246】 Furthermore, the conductive hole 114b is sealed with solder 115, as shown in Figure 15. The solder 115 connects, for example, the pattern on the surface (not shown) and the pattern on the back surface (not shown) of the substrate member 110. In addition to solder 115, the conductive hole 114b may also be sealed with a conductive material (for example, copper plating) that can electrically connect the patterns on the surface and back surface of the substrate member 110. 【0247】 As shown in Figures 16 and 17, the distance La~Ld,Lz between the location where the conductive hole 114b of the substrate member 110 is provided and the lower part of the second side wall portion 142f2 of the second case member 142 varies depending on the type of conductive hole 114b, such as the shape of the solder 115 used in the conductive hole 114b. The distance La~Ld,Lz is the distance between the location where the conductive hole 114b of the substrate member 110 is provided and the lower part of the second side wall portion 142f2, in a direction perpendicular to the surface of the substrate member 110. Alternatively, the minimum distance between the location where the conductive hole 114b of the substrate member 110 is provided and the second side wall portion 142f2 may be used as the distance La~Ld,Lz. 【0248】 First, as shown in Figure 16(a), if the solder 115 is provided on the substrate member 110 without any step difference and the surface of the solder 115 is flat, the distance between the location where the conductive hole 114b of the substrate member 110 is provided, i.e., the surface of the solder 115, and the lower part of the second side wall portion 142f2 is distance La. 【0249】 Next, as shown in Figure 16(b), if the surface of the solder 115 is raised, the distance between the location where the conductive hole 114b of the substrate member 110 is provided, i.e., the surface of the solder 115 and the lower part of the second side wall portion 142f2, becomes distance Lb. Distance Lb is shorter than distance La (Lb <La)。 【0250】 Next, as shown in Figure 16(c), when the test terminal 116 is installed on the surface of the solder 115, the distance between the location where the conductive hole 114b of the substrate member 110 is provided, that is, the upper part of the test terminal 116 and the lower part of the second side wall portion 142f2, is distance Lc. Distance Lc is shorter than distance Lb (Lc <Lb)。 【0251】 Furthermore, as shown in Figure 17(d), when the projection 142f3 protrudes from the second side wall 142f2 toward the conduction hole 114b, the lower part of the second side wall 142f2 becomes the tip of the projection 142f3. Therefore, the distance between the location where the conduction hole 114b is provided in the substrate member 110, i.e., the lower part of the conduction hole 114b, and the tip of the projection 142f3 is distance Ld. Distance Ld is extremely short compared to distance Lc (Ld < <Lc)。 【0252】 Furthermore, as shown in Figure 17(e), in the case of a conventional example where the solder 115 is not provided in the conductive hole 114b, the distance between the location of the conductive hole 114b in the substrate member 110 and the lower part of the second side wall portion 142f2 is distance Lz. Distance Lz is longer than distance La (Lz > La). 【0253】 The distances La to Ld described above are shorter than the distance Lz in the conventional example (Ld << Lc < Lb < La < Lz). Since the gap (space) between the location where the through-hole 114b of the substrate member 110 is provided and the lower part of the second side wall portion 142f2 can be made narrower, it is difficult for unauthorized access and it is easy to prevent fraud. Also, since the size of the gap can be changed according to the type of the through-hole 114b, such as the shape of the solder 115 and the shape of the second case member 142, the distance between the location vulnerable to unauthorized targeting according to the type of the through-hole 114b and the lower part of the second case member 142 can be shortened, such as the distance Lc or the distance Ld, to narrow the gap, making it easy to prevent fraud. 【0254】 〔Inspection Connector〕 Next, referring to FIG. 18, the relationship between the connector CN5 as the inspection connector of the substrate member 110 and the case 140 will be described. 【0255】 FIG. 18 is an enlarged perspective view and a front view of an enlarged periphery of the connector CN5 of the substrate member 110. 【0256】 As shown in the enlarged perspective view of FIG. 18(a), the connector CN5 is exposed to the outside from the opening 142e for the inspection connector of the second case member 142 in a state where the substrate member 110 is housed in the case 140. Also, the connector CN5 is exposed from the opening 142e in a direction perpendicular to the surface of the substrate member 110. 【0257】 As shown in the front view of FIG. 18(b), there is a gap of the first distance L1 between the connector CN5 and the edge of the opening 142e. The first distance L1 is a short distance so that unauthorized parts are difficult to be inserted into the gap. 【0258】 〔Specific Internal Connector〕 Next, referring to FIG. 19, the relationship between the connector CN2 as the specific internal connector of the substrate member 110 and the case 140 will be described. The connector CN2 can be connected to specific internal devices of the gaming machine 10, and for example, can be connected to the effect control device 300 for games. 【0259】 Figure 19 shows an enlarged perspective view and a front view of the area around the connector CN2 of the substrate member 110. 【0260】 As shown in the enlarged perspective view of Figure 19(a), when the substrate member 110 is housed in the case 140, the connector CN2 is exposed to the outside through the opening 142b for a specific internal connector in the second case member 142. The connector CN2 is also exposed through the opening 142b perpendicular to the surface of the substrate member 110. 【0261】 As shown in the front view of Figure 19(b), there is a gap of second distance L2 between the connector CN2 and the edge of the opening 142b. The second distance L2 is short to make it difficult for unauthorized parts to be inserted into the gap, and is, for example, the same distance as the first distance L1. Note that the first distance L1 may be shorter than the second distance L2 (L1 ≤ L2). 【0262】 [Second board specific internal connector] Next, referring to Figure 20, the relationship between the connector CN31 on the circuit board member 310 of the performance control device 300 and the case 340 will be explained. The connector CN31 mentioned above in Figure 11 is a specific internal connector (second circuit board specific internal connector) of the performance control device 300 as the second circuit board. The connector CN31 can be connected to specific internal equipment of the gaming machine 10, and can be connected to the gaming control device 100 for game purposes, for example. For example, the connector CN31 may be connected to the connector CN2 on the circuit board member 110 of the gaming control device 100. 【0263】 Figure 20 is an enlarged front view of the area around the connector CN31 of the circuit board component 310 of the performance control device 300. 【0264】 As shown in the front view of Figure 20, when the substrate member 310 is housed in the case 340, the connector CN31 is exposed to the outside through the opening 340a for the second substrate-specific internal connector in the case 340. The connector CN31 is also exposed through the opening 340a perpendicular to the surface of the substrate member 310. 【0265】 There is a gap with a third distance L3 between the connector CN31 and the edge of the opening 340a. The third distance L3 is a short distance so that an unauthorized part is difficult to be inserted into the gap, and for example, it is the same distance as the first distance L1. Note that the third distance L3 may be made longer than the first distance L1 (L3≧L1). 【0266】 In this way, the first distance L1 is set to a length equal to or less than the second distance L2 and the third distance L3 (L1≦L2, L1≦L3). Note that the second distance L2 can be set to a length equal to or less than the third distance L3 (L2≦L3, that is, L1≦L2≦L3). 【0267】 Here, when the connector CN5 as an inspection connector is not connected to an external inspection terminal, unauthorized access from the connector CN5 to the substrate member 110 is likely to occur. However, since the relationship of the first distance L1≦the second distance L2 and the third distance L3 is established, it is possible to prevent unauthorized access from the gap around the connector CN5 to the substrate member 110 using an unauthorized tool with a width larger than the second distance and the third distance. 【0268】 Furthermore, the first distance L1 may be set shorter than the second distance L2 and the third distance L3 (L1<L2, L1<L3). By making the first distance L1 the shortest in this way, even if an unauthorized tool is inserted through the gap around the connector CN2 or the connector CN31, the gap around the connector CN5 is the narrowest, making it more difficult to insert than the other gaps, and increasing the possibility that the same unauthorized tool cannot be reused. As a result, in order to perform unauthorized access from the connector CN5 to the substrate member 110, it is necessary to separately prepare and use an unauthorized tool shorter than the first distance L, so the deterrent force against unauthorized access can be increased. 【0269】 [Operation and Effect of the Second Embodiment] In this embodiment, the gaming machine 10 comprises a substrate (for example, the substrate member 110 of the gaming control device 100, the substrate member 310 of the performance control device 300) having a plurality of components (for example, a gaming microcontroller 111, ROM 111d, RAM 111e, resistor 111f, chip resistor 111g) on ​​its surface, and a case member (for example, case 140, case 340) that covers the substrate, the substrate having conductive holes (conductive holes 114a, 114b) for electrically connecting the front and back surfaces, and the case member (for example The second case member 142 of case 140 has side wall portions (first side wall portion 114f1, second side wall portion 114f2) that extend at an angle in a direction upright from the surface of the substrate, and the conductive holes are formed in a position that overlaps with the side wall portions in a direction perpendicular to the surface of the substrate when the substrate is housed in the case member, and the distance (distance La~Ld) between the location of the conductive hole on the substrate and the side wall portion of the case member differs depending on the type of conductive hole (shape of solder 115, shape of second case member 142, etc.). 【0270】 With this type of gaming machine 10, the size of the gap can be changed depending on the type of conductive hole, such as the shape of the solder 115 or the shape of the second case member 142. By shortening the distance between the area most susceptible to fraud and the bottom of the case member (the second case member 142 of the case 140) and narrowing the gap, fraud can be more easily prevented. As a result, fraudulent access can be further deterred, and the quality of the gaming machine 10 can be improved. 【0271】 In addition, the gaming machine 10 includes a substrate (for example, the substrate member 110 of the game control device 100, the substrate member 310 of the effect control device 300) having a plurality of components (for example, the game microcomputer 111, the ROM 111d, the RAM 111e, the resistor 111f, the chip resistor 111g) on its surface, and a case member (for example, the case 140, the case 340) covering the substrate. The substrate has through-holes (through-holes 114a, 114b) for electrically connecting the front surface and the back surface. The case member (for example, the second case member 142 of the case 140) includes side wall portions (the first side wall portion 114f1, the second side wall portion 114f2) extending at an angle in a direction rising from the surface of the substrate. When looking at the inside of the case member in a direction perpendicular to the side wall portions, components (electronic components, for example, the ROM 111d, the chip resistor 111g) are located at positions overlapping the side wall portions. 【0272】 According to such a gaming machine 10, components (electronic components) are arranged at positions overlapping the side wall portions when looking at the inside of the case member in a direction perpendicular to the side wall portions. Therefore, if the side wall portions of the case member are damaged, the electronic components arranged at the overlapping positions can also be easily involved and broken together, so it is easy to prevent the electronic components from operating in a state where fraud has been committed. 【0273】 In addition, the gaming machine 10 includes a substrate (for example, the substrate member 110 of the game control device 100, the substrate member 310 of the effect control device 300) having a plurality of components (for example, the game microcomputer 111, the ROM 111d, the RAM 111e, the resistor 111f, the chip resistor 111g) on its surface, and a case member (for example, the case 140, the case 340) covering the substrate. The substrate has through-holes (through-holes 114a, 114b) for electrically connecting the front surface and the back surface, an inspection connector for inspection, and a specific internal connector that can be connected to specific internal devices of the gaming machine. The case member (for example, the second case member 142 of the case 140) includes side wall portions (the first side wall portion 114f1, the second side wall portion 114f2) extending at an angle in a direction rising from the surface of the substrate. A plurality of the side wall portions are arranged between the inspection connector (connector CN2) and the specific internal connector (connector CN5). 【0274】 With this type of gaming machine 10, if the inspection connector is not connected to an external inspection terminal, the game is unlikely to be affected even if the inspection connector is damaged, so there is a possibility that fraud may be committed starting from the inspection connector. However, when attempting to commit fraud from the inspection connector side to a specific internal connector, it is not possible to access the specific internal connector without damaging two side walls of the case member (first side wall 142f1, second side wall 142f2), making it easier to prevent fraud. 【0275】 In addition, the gaming machine 10 includes a control device (game control device 100) that controls a game (variable display game), and related devices (effect control device 300, frame control device 200, power supply device 400) connected to the control device. The control device includes a first substrate (substrate member 110) and a first case member (case 140) that covers the first substrate. The related device (for example, the effect control device 300) includes a second substrate (substrate member 310) that can be connected to the first substrate and a second case member (case 340) that covers the second substrate. The first substrate has through holes (through holes 114a, 114b) for electrically connecting the front surface and the back surface, an inspection connector (connector CN5) for inspection, and a specific internal connector (connector CN2) that can be connected to specific internal devices of the gaming machine including the second substrate (for example, the effect control device 300, the frame control device 200, the power supply device 400). The first case member (second case member 142 of case 140) has side wall portions (first side wall portion 114f1, second side wall portion 114f2) that extend at an angle in a direction rising from the front surface of the first substrate, an inspection connector opening (opening 142e) that exposes the inspection connector in a direction perpendicular to the front surface of the first substrate, and a specific internal connector opening (opening 142b) that exposes the specific internal connector in a direction perpendicular to the front surface of the first substrate. The first distance (first distance L1) between the inspection connector and the edge of the inspection connector opening is the same as or shorter than the second distance (second distance L2) between the specific internal connector and the edge of the specific internal connector opening (L1≦L2). The second substrate has a second substrate specific internal connector (connector CN31) that can be connected to specific internal devices of the gaming machine including the first substrate. The second case member has a second substrate specific internal connector opening (opening 340a) that exposes the second substrate specific internal connector in a direction perpendicular to the front surface of the second substrate. The third distance (third distance L3) between the second substrate specific internal connector and the edge of the second substrate specific internal connector opening is the same as or longer than the first distance (L1≦L3). 【0276】 With this type of gaming machine 10, when the inspection connector is not connected to an external inspection terminal, it is easy for tampering to occur from the inspection connector to the first circuit board. However, since the first distance is less than or equal to the second distance L2 and the third distance L3, it is possible to suppress tampering to the first circuit board component from the gap around the inspection connector using a tampering device wider than the second and third distances. 【0277】 Furthermore, the gaming machine 10 includes a circuit board (for example, the circuit board member 110 of the gaming control device 100, the circuit board member 310 of the performance control device 300) having multiple components (for example, a gaming microcontroller 111, ROM 111d, RAM 111e, resistor 111f, chip resistor 111g) on ​​its surface, and a case member (for example, case 140, case 340) that covers the circuit board, and the circuit board includes conductive holes (conductive holes 114a, 114b) for electrically connecting the front and back surfaces, an inspection connector (connector CN2) for inspection, and specific internal equipment of the gaming machine 10 (for example The circuit board has a specific internal connector (connector CN2) that can be connected to the performance control device 300, the frame control device 200, and the power supply device 400), and the case member (for example, the second case member 142 of case 140) has side wall portions (first side wall portion 114f1, second side wall portion 114f2) that extend at an angle in the direction rising from the surface of the circuit board, and multiple side wall portions are arranged between the inspection connector and the specific internal connector, and at least one component (for example, resistor 111f, chip resistor 111g) is provided between the inspection connector and the specific internal connector of the circuit board. 【0278】 With this type of gaming machine 10, if the inspection connector is not connected to an external inspection terminal, even if the inspection connector is damaged, it is unlikely to affect the game (variable display game), so there is a possibility of fraud starting from the inspection connector. However, when attempting to fraudulently access a specific internal connector from the inspection connector side, it is not possible to access the specific internal connector without damaging two side walls of the case member (first side wall 142f1, second side wall 142f2), making it easier to prevent fraud. 【0279】 Furthermore, the gaming machine 10 comprises a circuit board (for example, circuit board member 110 of the gaming control device 100, circuit board member 310 of the performance control device 300) having multiple components (for example, a microcontroller for gaming 111, ROM 111d, RAM 111e, resistor 111f, chip resistor 111g), and a case member (for example, case 140, case 340) that covers the circuit board, and the circuit board has a two-dimensional code for the circuit board (two-dimensional codes for the circuit board 113d, 113e) on its surface, and part At least one of the parts has a two-dimensional code for the part (two-dimensional codes 113a, 113b, 113c) on the surface of the part, and the case member has a two-dimensional code for the case (two-dimensional codes 145a1, 145b1, 145c1) on the surface of the case member, and at least one of the two-dimensional codes for the part (for example, the two-dimensional code 113a of the gaming microcontroller 111) has a different orientation from the two-dimensional code for the circuit board and the two-dimensional code for the case. 【0280】 With this type of gaming machine 10, at least one orientation of the component's two-dimensional code is different from the orientation of the circuit board's two-dimensional code and the case's two-dimensional code. Therefore, if the orientation changes to one that is different, it is easy to recognize that there is a high probability that an unauthorized component has been installed. 【0281】 Furthermore, in the gaming machine 10, at least one component (for example, the gaming microcontroller 111) has character information ("CPUab12") representing information about the component on its surface, and at least one of the component's two-dimensional codes (for example, the two-dimensional code 113a of the gaming microcontroller 111) has a different orientation from the character information. 【0282】 With this type of gaming machine 10, at least one of the two-dimensional codes for parts and the character information representing the information of the part are oriented in different directions. Therefore, if they become the same orientation, it is easy to recognize that there is a high probability that an unauthorized part has been installed. 【0283】 Furthermore, the gaming machine 10 includes a circuit board (for example, a circuit board member 110 of the gaming control device 100, a circuit board member 310 of the performance control device 300) having multiple components (for example, a microcontroller for gaming 111, a ROM 111d, a RAM 111e, a resistor 111f, a chip resistor 111g), and a case member (for example, a case 140, a case 340) that covers the circuit board. The circuit board has multiple two-dimensional codes for the circuit board (two-dimensional codes for the circuit board 113d, 113e) on its surface, and the case member has two-dimensional codes for the case (two-dimensional codes for the case 145a1, 145b1, 145c1) on its surface, and the multiple two-dimensional codes for the circuit board are all the same size. 【0284】 In this type of gaming machine 10, the two-dimensional codes for the circuit boards are all the same size and are attached to the surface of the circuit board. Having the same size two-dimensional codes on the same plane eliminates the need to change the position of the two-dimensional code reader for focus adjustment, improving the efficiency of reading during inspection. As a result, the efficiency of inspection of the gaming machine 10 can be improved, and the quality of the gaming machine 10 can be enhanced. 【0285】 Furthermore, in the gaming machine 10, multiple two-dimensional codes for the case (two-dimensional codes 145a1, 145b1, 145c1 for the case) are attached to the surface of the case members (for example, case 140, case 340), and the multiple two-dimensional codes for the case are the same size, but are different in size from the multiple two-dimensional codes for the circuit board. 【0286】 With this type of gaming machine 10, since the case 2D codes are attached to the same planar layer, such as the surface of the case component, at the same size, the case 2D codes can be read in the same way at a nearly constant distance from the surface of the case component without having to move the 2D code reader back and forth to adjust the focus, making it easier to check the information on the circuit board. In addition, since the case 2D codes and the circuit board 2D codes are of different sizes, it is easier to prevent accidentally reading the circuit board 2D codes located on the far side of the planar layer when reading the case 2D codes located on the near side of the planar layer relative to the 2D code reader, thereby improving work efficiency. 【0287】 Furthermore, the gaming machine 10 includes a circuit board (for example, a circuit board member 110 of the gaming control device 100, a circuit board member 310 of the performance control device 300) having multiple components (for example, a microcomputer for gaming 111, a ROM 111d, a RAM 111e, a resistor 111f, a chip resistor 111g), and a case member (for example, a case 140, a case 340) that covers the circuit board. The circuit board has two-dimensional codes for the circuit board (two-dimensional codes 113d, 113e) on its surface, and the case member has two-dimensional codes for the case (two-dimensional codes 145a1, 145b1, 145c1) on its surface, and the two-dimensional codes for the circuit board are of a different size than the two-dimensional codes for the case. 【0288】 With this type of gaming machine 10, since the two-dimensional code for the circuit board is a different size from the two-dimensional code for the case, it is easier to prevent the two-dimensional code for the circuit board, which is located on the far side of the flat layer, from being mistakenly read when the two-dimensional code for the case, which is located on the far side of the flat layer, is being read by the two-dimensional code reader, thereby improving work efficiency. 【0289】 Furthermore, in the gaming machine 10, the two-dimensional codes for the circuit board (two-dimensional codes 113d, 113e) are smaller than the two-dimensional codes for the case (two-dimensional codes 145a1, 145b1, 145c1). 【0290】 In this type of gaming machine 10, the two-dimensional code for the circuit board, which is located on the flat layer at the back, is smaller than the two-dimensional code for the case. This makes it difficult to read the circuit board when it is illegally photographed, thus making it easier to prevent the illegal acquisition of information about the circuit board and its components. 【0291】 Furthermore, in the gaming machine 10, a seal is attached to the case components (for example, case 140, case 340) between the inspection connector (connector CN5) and a specific internal connector (connector CN2). With such a gaming machine 10, the seal makes it difficult to see inside, thus making it harder to commit fraud. 【0292】 Furthermore, in the gaming machine 10, the circuit board (for example, the circuit board component 110 of the gaming control device 100, the circuit board component 310 of the performance control device 300) has multiple game control execution components (for example, the gaming microcontroller 111, ROM 111d, RAM 111e), and none of the multiple game control execution components are located between the inspection connector (connector CN5) and the specific internal connector (connector CN2). With such a gaming machine 10, when someone attempts to tamper with the inspection connector from the specific internal connector side, the distance to the multiple game control execution components becomes greater, making it easier to prevent tampering with the multiple game control execution components in addition to tampering with the inspection connector. 【0293】 Note that the present invention is not limited to the embodiments described above, and various modifications and changes are possible within the scope of its technical idea, and it is clear that those are also included in the technical scope of the present invention. For example, it is also possible to replace the time-saving state with a probabilistic state. For example, part of the processing executed by the game control device can be executed by the effect control device, and conversely, part of the processing executed by the effect control device can be executed by the game control device. For example, it is also possible to combine various embodiments and various modification examples. In the above-described embodiment, an example in which the gaming machine 10 is configured by an enclosed pachinko machine (smart pachinko machine) has been described, but the above-described embodiment may be applied to an ordinary pachinko machine that is not enclosed. Furthermore, for example, the present invention can be applied not only to pachinko machines but also to other types of gaming machines (such as slot machines). The scope of the present invention is indicated by the claims, and it is intended that all changes within the meaning and scope equivalent to the claims are included. 【0294】 For example, when applying the above-described embodiment to a slot machine, the game medium used in the game becomes a medal (coin) instead of a game ball, and the number of prize balls is replaced by the number of medals paid out (awarded). The control of launching the game balls of the pachinko machine corresponds to the control of inserting medals (game media) in the slot machine. The number of game media used is the number of inserted medals, which is the number of medals inserted into the slot machine. And, for example, in a slot machine, the payout rate (base) as performance information is the ratio (%) of the number of medals paid out to the number of medals inserted into the slot machine, and the accessory ratio is the ratio (%) of the number of medals paid out by various bonuses among the number of medals paid out during a predetermined period. 【0295】 Also, in the above-described embodiment, the configuration of the board member 110 and the like of the game control device 100 has been described, but the same configuration as the above-described configuration may be applied to the board members of the frame control device 200, the effect control device 300, and the power supply device 400 to improve workability and prevent fraud. 【Explanation of Reference Numerals】 【0296】 10 Gaming Machines 30 game boards 50 Batch display device (LED) 100 Gaming control devices (control device, main board, gaming control board) 110 Substrate material 140 Case (Case Components) 300 Performance control device (sub-board)
