[0009] <<Embodiment 1>> Hereinafter, a gaming machine (slot machine) according to a first embodiment of the present invention will be described with reference to the drawings.

[0010] <Overall structure> First, the overall configuration of the slot machine 100 will be described with reference to Figure 1. Figure 1 is an external perspective view of the slot machine 100 as seen from the front side (player side).

[0011] The slot machine 100 shown in Fig. 1 corresponds to an example of a gaming machine of the present invention, and includes a main body 101 and a front door 102 attached to the front of the main body 101 and capable of opening and closing relative to the main body 101. Three reels (left reel 110, center reel 111, and right reel 112) with multiple types of symbols arranged on their outer peripheries are housed inside the center of the main body 101 (not shown), and are configured to be rotatable inside the slot machine 100. These reels 110 to 112 are driven to rotate by a drive device such as a stepping motor.

[0012] In this embodiment, an appropriate number of each symbol is printed at equal intervals on a strip-shaped member, and this strip-shaped member is attached to a predetermined circular cylindrical frame to form each of the reels 110-112 (see Figure 26). When viewed from the player, the symbols on the reels 110-112 are displayed in approximately three rows vertically through symbol display windows 113 provided in front of each of the reels 110-112, so that a total of nine symbols can be seen.

[0013] By spinning each of the reels 110-112, the combination of symbols visible to the player changes. In other words, each of the reels 110-112 functions as a display device that variably displays a combination of multiple types of symbols. Note that, in addition to reels, electronic image display devices such as liquid crystal display devices can also be used as such display devices. In addition, in this embodiment, three reels are provided inside the center of the slot machine 100, but the number of reels and the installation positions of the reels are not limited to this.

[0014] An optical sensor (also called an index sensor, not shown) consisting of a light-emitting section and a light-receiving section is provided near each of the reels 110 to 112 inside the slot machine 100, and a light-shielding piece of a certain length provided on the reel passes between the light-emitting section and the light-receiving section of this optical sensor. Based on the detection results of this sensor, the rotational position of the symbols on the reel is determined, and the reels 110 to 112 are stopped so that the target symbols are displayed on the pay line.

[0015] On the back of the reels 110 to 112, there are disposed reel backlights 264 (see Figures 7(a) and 8; details will be described later) for illuminating the individual symbols displayed in the symbol display windows 113. In addition, below the reels 110 to 112, there are disposed status display LEDs 280 (see Figure 3; details will be described later) for notifying various statuses of the slot machine 100. The reel panel lamps 128 are lamps for effect purposes.

[0016] The bet buttons 130 to 132 are buttons for inserting a predetermined number of medals (called credits) electronically stored in the slot machine 100. In this embodiment, each time the bet button 130 is pressed, one medal is inserted up to a maximum of three medals, when the bet button 131 is pressed, two medals are inserted, and when the bet button 132 is pressed, three medals are inserted. Hereinafter, the bet button 132 is also referred to as the MAX bet button.

[0017] The effect button 156 is an operating means that can be operated by the player. In this embodiment, it is configured as a button that can be pressed by the player and is used for various effects. The operating means used for such effects is not limited to a button, and may be configured as, for example, a lever or a touch panel, or multiple operating means may be provided.

[0018] The medal insertion slot 141 is an insertion slot through which a player inserts medals when starting a game. That is, medals can be inserted electronically using the bet buttons 130 to 132, or actual medals can be inserted (insertion operation) into the medal insertion slot 141, and the term "insertion" includes both.

[0019] The start lever 135 is a lever-type switch for starting the rotation of the reels 110 to 112. That is, when the desired number of medals are inserted into the medal insertion slot 141 or the bet buttons 130 to 132 are operated and the start lever 135 is operated, the reels 110 to 112 start to rotate. Operation of the start lever 135 is called a game start operation.

[0020] The stop button unit 136 is provided with stop buttons (stop buttons) 137 to 139. The stop buttons 137 to 139 are button-type switches for individually stopping the reels 110 to 112 that have started to rotate by operating the start lever 135, and are associated with each of the reels 110 to 112. Note that a light emitting element may be provided inside each of the stop buttons 137 to 139, and when the stop buttons 137 to 139 can be operated, the light emitting element can be lit to notify the player.

[0021] Hereinafter, operations on stop buttons 137 to 139 will be referred to as stop operations, with the first stop operation being referred to as the first stop operation (hereinafter also referred to as "first stop" or "first stop"), the next stop operation being referred to as the second stop operation (hereinafter also referred to as "second stop" or "second stop"), and the final stop operation being referred to as the third stop operation (hereinafter also referred to as "third stop" or "third stop").

[0022] The reels that are stopped in response to these stop operations are referred to as the first stop reel, the second stop reel, and the third stop reel, respectively. Furthermore, the order in which the stop buttons 137 to 139 are operated to stop all of the reels 110 to 112 that are spinning is referred to as the operation order (or push order).

[0023] The operation sequence (pressing order) of the stop buttons 137 to 139, when the left stop button 137 is represented as "left or R", the middle stop button 138 as "middle or C", and the right stop button 139 as "right or R", are six types: (1) left-to-middle-to-right operation sequence (left-right-right or LCR), (2) left-to-right-to-middle operation sequence (left-right-center or LRC), (3) middle-to-left-to-right operation sequence (center-left-right or CLR), (4) middle-to-right-to-left operation sequence (center-right-left or CRL), (5) right-to-left-to-middle operation sequence (right-left-center or RLC), and (6) right-to-middle-to-left operation sequence (right-center-left or RCL).

[0024] The medal return button 133 is a button that can be pressed to remove medals that have been inserted and become stuck. The settlement button 134 is a button that can be used to settle medals electronically stored in the slot machine 100 and medals that have been bet, and to dispense them from the medal payout outlet 155. The door key hole 140 is a hole into which a key can be inserted to unlock the front door 102 of the slot machine 100.

[0025] Below the stop button unit 136, there is provided a title panel 162 on which the model name is displayed and various certificate stamps are attached. Below the title panel 162, there are provided a medal payout outlet 155 and a medal tray 161. The sound hole 181 is a hole for outputting sound from a speaker provided inside the slot machine 100 to the outside. The side lamps 144 provided on the left and right sides of the front door 102 are decorative lamps for livening up the game. A performance device 160 is provided above the front door 102, and a sound hole 143 is provided above the performance device 160.

[0026] This presentation device 160 is equipped with a shutter (shielding device) 163 consisting of two shutters, a right shutter 163a and a left shutter 163b, which can be opened and closed horizontally, and a liquid crystal display device 157 (presentation image display device) arranged at the back of this shutter 163, and is configured so that when the right shutter 163a and the left shutter 163b are opened horizontally outward in front of the liquid crystal display device 157, the display screen of the liquid crystal display device 157 appears in front of the slot machine 100 (on the player's side).

[0027] Note that any display device capable of displaying various effect images and various game information may be used, not limited to a liquid crystal display device. For example, a multi-segment display (7-segment display), a dot matrix display, an organic EL display, a plasma display, a reel (drum), or a display device consisting of a projector and a screen may be used. The display screen is rectangular and configured so that the entire screen is visible to the player. In this embodiment, the display screen is rectangular, but it may also be square. Furthermore, decorations (not shown) may be provided around the periphery of the display screen, so that a portion of the periphery of the display screen is hidden by the decoration, making the display screen appear irregularly shaped. In this embodiment, the display screen is flat, but it may also be curved.

[0028] Also provided inside the main body 101 are a setting key that can be turned on and off by a rotation operation, and a setting switch that can be pressed down to change settings (change setting values) or check settings. The setting key is an operating means for starting to change or check setting values ​​(settings 1 to 6 in this example), and the setting switch is one of the setting means that can set one setting value out of multiple setting values.

[0029] <Winning line> Next, the pay lines will be described with reference to Figure 2. Figure 2 is a diagram showing an example of the pay lines of the slot machine 100.

[0030] As explained using Figure 1, when viewed from the player, the symbols on the reels 110 to 112 are displayed in approximately three rows vertically through the symbol display windows 113 provided in front of each reel 110 to 112, so that a total of nine symbols can be seen.

[0031] Specifically, the symbol displayed on the top row of the left reel 110 (position 1 shown in the figure; also called symbol position 1) is called the left reel top row symbol, the symbol displayed on the middle row of the left reel 110 (position 2 shown in the figure; also called symbol position 2) is called the left reel middle row symbol, and the symbol displayed on the bottom row of the left reel 110 (position 3 shown in the figure; also called symbol position 3) is called the left reel bottom row symbol.

[0032] In addition, the pattern displayed on the top row of the middle reel 111 (position 4 shown in the figure; also called pattern position 4) is called the top row of the middle reel pattern, the pattern displayed on the middle row of the middle reel 111 (position 5 shown in the figure; also called pattern position 5) is called the middle row of the middle reel pattern, and the pattern displayed on the bottom row of the middle reel 111 (position 6 shown in the figure; also called pattern position 6) is called the bottom row of the middle reel pattern.

[0033] In addition, the symbol displayed on the top row of the right reel 112 (position 7 shown in the figure; also called symbol position 7) is called the right reel top row symbol, the symbol displayed on the middle row of the right reel 112 (position 8 shown in the figure; also called symbol position 8) is called the right reel middle row symbol, and the symbol displayed on the bottom row of the right reel 112 (position 9 shown in the figure; also called symbol position 9) is called the right reel bottom row symbol.

[0034] In this embodiment, the only winning line provided is the middle winning line L1 (hereinafter sometimes simply referred to as the "winning line L1"), which is composed of the middle pattern of the left reel (pattern position 2), the middle pattern of the middle reel (pattern position 5), and the middle pattern of the right reel (pattern position 8).

[0035] Here, the winning line is a line set at the stop position of the symbols visible through the symbol display window 113, and is a line that determines whether or not a symbol combination corresponding to a winning role is displayed (whether or not it is aligned). The winning line that becomes effective (hereinafter, may be simply referred to as "effective line") is predetermined by the number of medals bet as gaming media.

[0036] The slot machine 100 of this embodiment is a three-coin bet-only machine, and when the number of inserted medals is less than three, no winning line is active, and when three medals are bet, the winning line L1 is active. When the winning line is active, the start lever 135 can be operated to start the game.

[0037] Hereinafter, in the symbol display window 113, symbol positions 2, 5, and 8 on the winning line L1 may be referred to as "winning positions," and other symbol positions, i.e., symbol positions 1, 3, 4, 6, 7, and 9, may be referred to as "non-winning positions." In other words, a winning position is a position on the winning line where a symbol that constitutes a symbol combination corresponding to a winning combination stops.

[0038] The number of winning lines is not limited to one. For example, in addition to the winning line L1, three lines in total may be set as valid winning lines: an upper winning line consisting of the upper symbols on the left reel, the upper symbols on the middle reel, and the upper symbols on the right reel, and a lower winning line consisting of the lower symbols on the left reel, the lower symbols on the middle reel, and the lower symbols on the right reel. Alternatively, a number of winning lines corresponding to the number of medals bet may be set as valid winning lines.

[0039] <Status display LED> Next, a description will be given of the status display LED 280. Fig. 3 is a front view of the status display LED 280, and Fig. 4 is an exploded perspective view showing the members that make up the status display LED 280.

[0040] <Status display LED / Upper display> As shown in FIG. 3, on the upper row of the status display LED 280, a medal insertion possible display section 124, a game start display section 121, a replay display section 122, and a medal insertion display section 129 are arranged.

[0041] The medal insertion enable display unit 124 is a display unit for informing the player that it is now possible to insert a medal, and lights up the word "INSERT" when the player is ready to insert a medal.

[0042] The game start display unit 121 is a display unit for notifying that the game can be started when the specified number of medals have been inserted, and lights up the word "START" when the game can be started.

[0043] The replay display unit 122 is a display unit for informing the player that the current game can be replayed (no medal insertion is required) if a replay role, which is one of the winning roles, was won in the previous game, and lights up the word "REPLAY" if a replay role, which is one of the winning roles, was won in the previous game.

[0044] The medal insertion display unit 129 is a display unit for lighting up a number of lamps corresponding to the number of medals inserted, and when one medal is inserted, the string "1BET" lights up, when two medals are inserted, the string "2BET" lights up, and when three medals are inserted, the string "3BET" lights up.

[0045] As shown in Figure 4, the medal insertion possible display unit 124, the game start display unit 121, the replay display unit 122, and the medal insertion display unit 129 in this example are all composed of an LED board 288 (first board), a plurality of LEDs 286 (second light-emitting means) arranged in a light-colored area 288a (second area, the area where a light-colored coating is formed) on the mounting surface of this LED board 288 (first board) where a white coating silk is applied, a reflector 284 (first partitioning member) which partitions a rectangular opening 284a (space) through which light from the plurality of LEDs 286 (second light-emitting means) passes, and a character sheet 282 (first irradiated member) onto which light from the plurality of LEDs 286 (light-emitting means) is irradiated.

[0046] Here, the term "bright color" according to the present invention refers to a color with high brightness, such as white, yellow, or light blue.

[0047] A semi-transparent member having the character string "INSERT" is disposed on the letter sheet 282 that constitutes the medal insertion possible display unit 124. When the plurality of LEDs 286 that constitute the medal insertion possible display unit 124 are turned on, the character string "INSERT" is illuminated to notify that the operation to start a game is possible.

[0048] A semi-transparent member having the character string "START" is disposed on the character sheet 282 constituting the game start display unit 121. When the plurality of LEDs 286 constituting the game start display unit 121 are turned on, the character string "START" is illuminated to notify that the game start operation is possible.

[0049] A semi-transparent member consisting of the character string "REPLAY" is disposed on the character sheet 282 that constitutes the replay display unit 122. When the plurality of LEDs 286 that constitute the replay display unit 122 are turned on, the character string "REPLAY" is illuminated to indicate that the current game can be played again (no medal insertion is required).

[0050] A translucent member having character strings of "3BET," "2BET," and "1BET" is disposed on the character sheet 282 constituting the medal insertion display unit 129. Among the plurality of LEDs 286 constituting the gaming medal insertion display unit 129, when the LED 286 corresponding to the character sheet 282 for "3BET" is turned on, the character string "3BET" is emitted to indicate that three medals have been inserted, when the LED 286 corresponding to the character sheet 282 for "2BET" is turned on, the character string "2BET" is emitted to indicate that two medals have been inserted, and when the LED 286 corresponding to the character sheet 282 for "1BET" is turned on, the character string "1BET" is emitted to indicate that one medal has been inserted.

[0051] <Status display LED / lower display> As shown in FIG. 3, below the status display LED 280, a stored coin number display section 125, a game information display section 126, and a payout coin number display section 127 are arranged.

[0052] The stored medal number display unit 125 is a display unit for displaying the number of medals electronically stored in the slot machine 100 as a two-digit number.

[0053] The payout number display unit 127 is a display unit for displaying, in a two-digit number, the number of medals to be paid out to a player as a result of winning some kind of winning combination.

[0054] As shown in Figure 4, both the stored number display unit 125 and the dispensed number display unit 127 in this example are composed of an LED board 288 (first board), a plurality of LEDs 286 (second light-emitting means) arranged in a light-colored area 288a (second area, the area where a light-colored coating is formed) on the mounting surface of the LED board 288 (first board) where a white coating silk is applied, a reflector 284 (first partitioning member) which partitions a rectangular opening 284a (space) and an opening 284b (space) in the shape of a two-digit seven-segment display through which light from the plurality of LEDs 286 (second light-emitting means) passes, and a character sheet 282 (first irradiated member) onto which light from the plurality of LEDs 286 (light-emitting means) is irradiated.

[0055] A semi-transparent member consisting of the character string "CREDIT" and a semi-transparent member consisting of the shape of a two-digit seven-segment display corresponding to the opening 284b are arranged on the character sheet 282 (first irradiated member) constituting the stored number display unit 125. Then, when the LED 286 (second light-emitting means) corresponding to the character sheet 282 of "CREDIT" among the plurality of LEDs 286 (second light-emitting means) constituting the stored number display unit 125 is turned on, the character string "CREDIT" is illuminated, and by turning on the LED 286 (second light-emitting means) corresponding to the two-digit seven-segment display, the number of medals electronically stored can be displayed as a two-digit numerical value.

[0056] A translucent member having the character string "PAYOUT" and a translucent member having the shape of a two-digit seven-segment display are arranged on the character sheet 282 (first irradiated member) constituting the payout number display unit 127. Then, among the plurality of LEDs 286 (second light-emitting means) constituting the payout number display unit 127, when the LED 286 (second light-emitting means) corresponding to the character sheet 282 of "PAYOUT" is turned on, the character string "PAYOUT" is illuminated, and by turning on the LED 286 (second light-emitting means) corresponding to the two-digit seven-segment display, the number of medals to be paid out to the player can be displayed as a two-digit number.

[0057] The game information display unit 126 is a display for displaying internal information of the slot machine 100 (for example, setting values, error codes, etc.) in four-digit numbers, and is also used as an instruction monitor for performing push order navigation effects.

[0058] The game information display unit 126 in this example is composed of an LED board 288 (first board), a plurality of LEDs 286 (first light-emitting means) arranged in a dark area 288b (first area; an area where a dark coating is formed, shown by a dotted line in Figure 4) on the mounting surface of this LED board 288 (first board) where a black coating resist is applied, a reflector 284 (first partitioning member) which partitions an opening 284c (space) in the shape of a four-digit seven-segment display through which light from the plurality of LEDs 286 (first light-emitting means) passes, and a character sheet 282 (first irradiated member) onto which light from the plurality of LEDs 286 (first light-emitting means) is irradiated.

[0059] In addition, the gaming information display unit 126 in this example is configured so that the opening 284c is in the shape of a seven-segment display that is smaller than the opening 284b. Also, the plurality of LEDs 286 that make up the gaming information display unit 126 are configured so that they are more densely packed (the spacing between adjacent LEDs is narrower) than the plurality of LEDs 286 that make up the stored coin number display unit 125 or the payout coin number display unit 127, so that they form the shape of a seven-segment display. In this way, the gaming information display unit 126 is configured as a light-emitting area that is smaller than the stored coin number display unit 125 or the payout coin number display unit 127.

[0060] Here, the term "dark color" according to the present invention refers to a color with low brightness, such as black, navy blue, brown, gray, or dark blue.

[0061] When the coating film of the LED substrate 288 and the coating film of the dark color region 288b are the same color, the region on the LED substrate 288 that corresponds to the opening 284c is defined as the "first region" according to the present invention. On the other hand, when the coating film of the LED substrate 288 and the coating film of the dark color region 288b are different colors, the dark color region 288b having the different colors may be defined as the "first region" according to the present invention, or the region on the LED substrate 288 that corresponds to the opening 284c may be defined as the "first region" according to the present invention.

[0062] A semi-transparent member in the shape of a four-digit seven-segment display corresponding to the opening 284c is disposed on the character sheet 282 (first illuminated member) constituting the game information display unit 126. Then, by lighting up a plurality of LEDs 286 (first light-emitting means) constituting the game information display unit 126, internal information of the slot machine 100 (for example, setting values, error codes, etc.) and instruction monitor information can be displayed in numerical values.

[0063] According to this example, the multiple LEDs 286 (first light-emitting means) that make up the game information display unit 126 are arranged in a dark area 288b (first area, an area where a dark coating is formed) on the mounting surface of the LED board 288 (first board), where a black coating resist is applied. This prevents the LEDs 286 (first light-emitting means) from reflecting part of the LEDs 286 (first light-emitting means) due to external light (external light), which can make the LEDs 286 (first light-emitting means) appear to be lit even when they are off. This allows accurate game information to be provided to the player, and avoids causing any disadvantage to the player. In addition, the weak lighting (ghost lighting) of the LEDs 286 (first light-emitting means) due to a weak current when the LEDs are off can be made less noticeable, preventing situations where the player is misled by an incorrect display.

[0064] Furthermore, the multiple LEDs 286 (first light-emitting means) that make up the game information display unit 126 are light-emitting means that make up a notification means that notifies information (e.g., the order in which to press) that corresponds to advantageous operation modes for stop operation means that can stop the reels (e.g., stop buttons 137 to 139). Therefore, it is possible to prevent the misunderstanding that an operation mode is being notified when it is not, and it is possible to provide accurate information to the player and avoid causing any disadvantage to the player.

[0065] Furthermore, the multiple LEDs 286 (first light-emitting means) that make up the game information display unit 126 are light-emitting means that make up a notification means that notifies information corresponding to an error (for example, an error code), so it is possible to prevent the player from misunderstanding that an error is being notified when no error is being notified, and it is possible to provide the player with accurate information and avoid causing any disadvantage to the player.

[0066] The multiple LEDs 286 (first light-emitting means) of the game information display unit 126 are light-emitting means that can emit light in a first state (e.g., AT state or error state), and the multiple LEDs 286 (second light-emitting means) of the stored medal count display unit 125 and the payout medal count display unit 127 are light-emitting means that can emit light in a second state (e.g., medal storage or payout), and the multiple LEDs 286 (second light-emitting means) that constitute the stored medal count display unit 125 (second light-emitting means) and the payout medal count display unit 127 are arranged in a light-colored area 288a (second area; area where a light-colored coating film is formed) to which white coating film silk is applied.

[0067] Furthermore, during play, the number of times the machine transitions to the AT state or error state is relatively less than the number of times medals are stored or paid out, and the frequency of entering the second state (storage or payment of medals) is higher than the frequency of entering the first state (AT state or error state).

[0068] Not only when the number of medals stored or paid out is one or more, but even when the number of medals stored or paid out is zero, the stored medal number display unit 125 and the paid out medal number display unit 127 display "0" (or "00").In other words, it can be said that the stored medal number display unit 125 and the paid out medal number display unit 127 continuously display some kind of light while the game is in progress or is ready to be played.

[0069] In contrast, the AT state and error state are states that occur as a result of specific conditions that arise during play or when play is possible, and therefore, it can be said that the AT state and error state occur less frequently than during play or when play is possible. Also, even in the AT state or error state, the stored coin number display unit 125 and the payout coin number display unit 127 are configured to continue to be lit, so it can be said that the stored coin number display unit 125 and the payout coin number display unit 127 light up more frequently than the game information display unit 126.

[0070] This improves the visibility of the LED 286 (second light-emitting means) of the number of coins stored display unit 125 (second light-emitting means) and the number of coins paid out display unit 127, which emit light more frequently (have a higher display update frequency) than the game information display unit 126, thereby improving convenience for players.

[0071] In addition, the game information display unit 126 is positioned so as to be sandwiched between the stored coin number display unit 125 and the payout coin number display unit 127, and the dark area 288b (first area, area where a dark coating is formed) where the game information display unit 126 is positioned and is coated with a black coating resist is sandwiched on both sides by the light area 288a (second area, area where a light coating is formed) where the stored coin number display unit 125 is positioned and is coated with a white coating silk, and the light area 288a (second area, area where a light coating is formed) where the payout coin number display unit 127 is positioned and is coated with a white coating silk.

[0072] According to this example, it is possible to prevent the LED286 (second light-emitting means) arranged in the light color region 288a (second region; region where a light color coating is formed) on one side of the dark color region 288b (first region; region where a dark color coating is formed) from affecting the LED286 (second light-emitting means) arranged in the light color region 288a (second region; region where a light color coating is formed) on the other side of the dark color region 288b (first region; region where a dark color coating is formed), and it is possible to make the notification by the LED286 (second light-emitting means) easier to see.

[0073] Furthermore, by arranging the dark color region 288b and the light color region 288a adjacent to each other, the LED 286 (second light-emitting means) arranged in the light color region 288a can make ghost lighting in the LED 286 (first light-emitting means) arranged in the dark color region 288b less noticeable compared to when the dark color regions 288b are adjacent to each other.

[0074] Furthermore, the status display LED 280 has a dark area 288b (first area; area where a dark coating is formed) coated with a black coating resist, and a light area 288a (second area; area where a light coating is formed) coated with a white coating silk, so the light emission mode (brightness, etc.) of the LED 286 can be changed simply by changing the color of the coating applied to the board on which the LED 286 is placed (hardware change) without changing the contents (program change) of the control driver (software) that controls the status display LED 280, making it easy to change the specifications of the gaming machine, etc.

[0075] In this example, the multiple LEDs 286 (first light-emitting means) constituting the game information display unit 126 and the multiple LEDs 286 (second light-emitting means) constituting the other display units (medal insertion possible display unit 124, game start display unit 121, replay display unit 122, medal insertion display unit 129, number of stored coins display unit 125, number of payout coins display unit 127) are mounted on the same LED board 288 (first board), but the present invention is not limited to this, and the multiple LEDs 286 may be mounted on multiple different boards.

[0076] Therefore, for example, a dark area 288b (first area, an area where a dark coating film is formed) coated with a black coating film resist may be formed on a certain substrate, and a light area 288a (second area, an area where a light coating film is formed) coated with a white coating film silk may be formed on a different substrate.

[0077] In addition, in this example, a specific area of ​​the LED substrate 288 coated with black coating resist is coated with white coating silk, but it is also possible to coat a specific area of ​​the LED substrate coated with white coating resist with black coating.

[0078] <Status display LED / unitized> FIG. 5 is a cross-sectional view of the status indicator LED 280, including the heat crimped portion 284d of the reflector 284.

[0079] The LED substrate 288 is configured to have a through-hole 288d with an inner diameter w4, and an insertion hole 288c with an inner diameter w5 (w5>w4) into which the thermal caulking portion 284d of the reflector 284 can be inserted. A plurality of LEDs 286 with a width w7 and a height h4 are mounted on the mounting surface of this LED substrate 288.

[0080] Reflector 284 is configured to have multiple types of openings 284a to 284c and thermally crimped portion 284d as described with reference to Fig. 4. Thermally crimped portion 284d is made of a rod-shaped body having an outer diameter w5 and formed to extend in the thickness direction of reflector 284 (Fig. 5 shows thermally crimped portion 284d after it has been deformed by heating).

[0081] After inserting the thermal crimping portion 284c of the reflector 284 into the insertion hole 288d of the LED substrate 288, heat is applied to the tip of the thermal crimping portion 284d to soften it, and then pressure is applied to crush it, thereby forming a deformed portion 284d2 at the tip of the thermal crimping portion 284d having an outer diameter w6 (w6>w5) larger than the inner diameter w5 of the thermal crimping portion 284d of the LED substrate 288.

[0082] As a result, the reflector 284 is fixed by caulking to the mounting surface of the LED substrate 288, and the reflector 284 and the LED substrate 288 are integrated together. The character sheet 282 is also arranged so as to cover the openings 284a to 284d of the reflector 284, and is attached to the surface of the reflector 284.

[0083] That is, the reflector 284 (first partitioning member) is fixed by crimping to the mounting surface of the LED substrate 288 (first substrate), and the character sheet 282 (first irradiated member) is attached to the reflector 284 (first partitioning member), thereby forming the LED substrate 288 (first substrate), the reflector 284 (first partitioning member), and the character sheet 282 (first irradiated member) into a unit.

[0084] According to this example, the LED board 288 (first board), the reflector 284 (first partitioning member), and the character sheet 282 (first irradiated member) are unitized, which facilitates the replacement of the status display LED 280 and the incorporation into the gaming machine, thereby improving work efficiency.

[0085] In this example, the deformation portion 284d2 is formed at a position that protrudes by a height h5 from the rear surface of the substrate 288, leaving a gap (gap) between the reflector 284 and the LED substrate 288, but the deformation portion 284d2 may be in close contact with the rear surface of the LED substrate 288.

[0086] <Status display LED / Variation 1> Next, the status display LED 750 according to the first modification will be described with reference to FIGS. 6(a) and 6(b).

[0087] Fig. 6(a) is a cross-sectional view of the status display LED 750 according to the first modification, and corresponds to the cross-sectional view of the status display LED 280 shown in Fig. 5. Fig. 6(b) is a bottom view of the status display LED as seen from the direction indicated by the symbol A in Fig. 6(a).

[0088] In the following, in order to avoid redundant explanation, only the configuration that differs from the status display LED 280 explained using FIG. 5 will be explained.

[0089] The status display LED 750 is composed of an LED substrate (first substrate) 751, a plurality of LEDs (second light-emitting means) 752 arranged on the mounting surface of the LED substrate 751, a reflector (first partitioning member) 753 which defines an opening (space) 753a through which light from the plurality of LEDs 752 passes, a character sheet (first irradiated member) 754 onto which light from the plurality of LEDs 752 is irradiated, a cover member 755 arranged on the surface opposite the mounting surface of the LED substrate 751, and a connector 756 (shown only in Figure 6(b)) which is electrically connected to the LEDs 752 and other electronic components mounted on the LED substrate 751.

[0090] The LED substrate 751 and the cover member 755 each have a cylindrical insertion hole 751a, 755a having an inner diameter w9 (w9>w8) slightly larger than the outer diameter w8 of the thermal crimping portion 753a before deformation, into which the thermal crimping portion 753a before deformation can be inserted.

[0091] According to this example, the LED substrate 751 and the cover member 755 are formed with insertion holes 751a, 755a having an inner diameter w9 that is slightly larger than the outer diameter w8 of the thermal crimping portion 753a before deformation, making it easier to insert the thermal crimping portion 753a of the reflector 753 into the LED substrate 751 or the cover member 755, improving work efficiency when assembling the status display LED 750. Furthermore, even if the thermal crimping portion 753a expands after assembly due to heat generated from the LED 752 or the LED substrate 751, the volume of the expanded thermal crimping portion 753a can be absorbed by the gap, preventing damage to the LED substrate 751 or the cover member 755. Furthermore, by making the inner diameter w9 slightly larger than the outer diameter w8, a small amount of "play" space is formed, which reduces the risk of damage to the LED board 751, cover member 755, reflector 753, thermal crimping portion 753a (including the cylindrical rod-shaped body leading up to the thermal crimping portion 753a), etc. when the gaming machine is transported or subjected to vibration.

[0092] The thermal crimping portion 753a of the reflector 753 consists of a cylindrical rod-shaped body extending in the thickness direction of the reflector 753 (Figure 6(a) shows the thermal crimping portion 753a after its tip has been deformed by heating).

[0093] The thermal crimping portion 753a before deformation is inserted into the insertion hole 751a of the LED substrate 751 and the insertion hole 755a of the cover member 755, and then heat is applied to the tip of the thermal crimping portion 753a to soften it, and pressure is applied to crush it, thereby forming a deformed portion 753a1 at the tip of the thermal crimping portion 753a having an outer diameter w10 (w10>w9) larger than the inner diameter w9 of the insertion hole 751a of the LED substrate 751 and the insertion hole 755a of the cover member 755.

[0094] As a result, the reflector 753 is fixed by caulking to the LED substrate 751 and the cover member 755, and the reflector 753, the LED substrate 751, and the cover member 755 are integrated together. The character sheet 754 is disposed so as to cover the opening 753a of the reflector 753, and is attached to the surface of the reflector 753.

[0095] That is, one side of the reflector 753 is crimped to the LED board 751 and the cover member 755, and the character sheet 754 is attached to the other side, thereby forming the LED board 751, the cover member 755, the reflector 753, the LED 752, and the character sheet 754 into a unit.

[0096] In this example, the LED board 751, cover member 755, reflector 753, LED 752, and character sheet 754 are unitized, which makes it easier to replace the status display LED 750 and to incorporate it into the gaming machine, thereby improving work efficiency.

[0097] Also, as shown in FIG. 6(b), the unit of the status display LED 750 (LED substrate 751, cover member 755, reflector 753, LED 752, and character sheet 754) has a polygonal shape with four chamfered corners when viewed from the bottom, and the deformation portions 753a1 of the thermal crimping portion 753a are arranged one on each of the four corners of the LED substrate 751 and the cover member 755, and one in the center of the LED substrate 751 and the cover member 755.

[0098] That is, the LED substrate 751 and the cover member 755 are fixed by crimps provided along the outer shapes of the LED substrate 751 and the cover member 755 and crimps provided further inward than the crimps. Furthermore, the crimps provided further inward are located closer to the connector 756 than the crimps provided further outward. Furthermore, the connector 756 is not located in the center of the status display LED 750, but is located to the right in the left-right direction and lower in the up-down direction, and is disposed eccentrically to at least one of the up-down, left-right, and right-hand sides from the center.

[0099] According to this example, the unit of the status display LED 750 has a polygonal shape with four chamfered corners, which makes it easy to incorporate into the mounting part of the gaming machine and improves work efficiency.

[0100] Furthermore, by providing deformation portions 753a1 of thermal crimping portion 753a on the corner side (outer crimp) of LED substrate 751 or cover member 755 and on the center side (inner crimp) of LED substrate 751 or cover member 755, it is possible to suppress rattle of LED substrate 751 or cover member 755. In this example, a gap is provided between the tip end of thermal crimping portion 753a and cover member 755, and stability can be improved by providing an inner crimp in addition to the outer crimp.

[0101] Furthermore, the crimps provided on the inside are located closer to the connector 756 than the crimps provided on the outside, which also contributes to suppressing rattle when inserting or removing the harness.

[0102] Furthermore, by arranging the connector 756 off-center to at least one of the top, bottom, left, and right sides of the center of the status display LED 750, the connector 756 can also be used as a handle when removing the LED substrate 751 from the reflector 753. Furthermore, when disassembling the status display LED 750, it is also possible to remove the LED substrate 751 from the reflector 753 by simply destroying the thermally crimped portion on only one side, without destroying the deformation portions 753a1 of all of the thermally crimped portions 753a.

[0103] Furthermore, when a wiring pattern for transmitting a signal or a wiring pattern for supplying a predetermined voltage is formed near the insertion hole 751a of the LED substrate 751, the wiring pattern is formed so as to avoid or detour around the insertion hole 751a, but the wiring pattern may be formed so as to detour inward rather than outwardly around the LED substrate 751. Specifically, for example, in Fig. 6(b), where there are crimps located on the outside of the LED substrate 751 and crimps located on the inside, the wiring pattern is formed so as to detour inward of the substrate near the crimps located on the outside (no wiring pattern is formed between the insertion hole 751a and the end of the substrate closest to the insertion hole 751a).

[0104] This prevents damage to the wiring pattern when a crack occurs from the edge of the substrate toward the insertion hole 751a. Damage to the wiring pattern not only prevents signals and voltages from being transmitted properly, but also creates resistance, which can cause the damaged area to heat up and potentially catch fire. However, by routing the wiring pattern inward, this risk can be reduced. Furthermore, when disassembling the LED unit, routing the wiring pattern inward allows tools to be inserted from the edge of the substrate, preventing damage to the wiring pattern.

[0105] Furthermore, the LED substrate 751 is colored black, the reflector 753 is colored white, and the connector 756 is colored blue, so that the LED substrate 751, the reflector 753, and the connector 756 are colored differently.

[0106] According to this example, when replacing the reflector 753, there is no risk of accidentally cutting the connector 756 when cutting the deformed portion 753a1 of the thermal crimping portion 753a, and work errors can be prevented in advance.

[0107] In this example, the cover member 755 is provided on the surface opposite to the mounting surface of the LED substrate 751, but a cover member need not be provided as in the case of the status display LED 280 described with reference to Fig. 5. Also, although the example has been shown in which the LED substrate 751 is colored black, the reflector 753 is colored white, and the connector 756 is colored blue, the types of colors are not particularly limited, and it is preferable that they are different colors.

[0108] <Status display LED / Variation 2> Next, the status display LED 760 according to the second modification will be described with reference to FIG. 6(c).

[0109] FIG. 6(c) is a cross-sectional view of a status display LED 760 according to Modification 2, and corresponds to the cross-sectional view of the status display LED 750 shown in FIG. 6(a).

[0110] In this example, the thermal crimping portion 763a of the reflector 763 before deformation is inserted into the insertion hole 761a of the LED substrate 761, and then heat is applied to the tip of the thermal crimping portion 763a to soften it, and the thermal crimping portion 763a is formed into a trapezoidal shape in side view that gradually widens toward the tip, with the LED substrate 761 as the base end, so that a deformed portion 763a1 is formed at the tip of the thermal crimping portion 763a having an outer diameter w12 (w12>w11) that is larger than the inner diameter w11 of the insertion hole 761a of the LED substrate 761.

[0111] In this deformed portion 763a1, the height h5 of the gap from the tip to the LED substrate 761 is greater than the height h6 of the gap from the center to the LED substrate 761 (h5>h6).

[0112] According to this example, the deformed portion 763a1 of the thermal crimping portion 763a has a trapezoidal shape (expanding shape) in a side view that gradually widens from the LED substrate 761 as its base end toward the tip. Therefore, when replacing the reflector 763, it is easy to insert a blade or the like, which increases the efficiency of the cutting work of the deformed portion 763a1 of the thermal crimping portion 763a. At the same time, the reflector 763 is firmly fixed to the LED substrate 761 at the base of the deformed portion 763a1 (the contact point between the deformed portion 763a1 and the LED substrate 761), so the reflector 763 can be stably supported by the LED substrate 761.

[0113] <Internal structure> Next, the internal structure of the slot machine 100 will be described with reference to Figure 7. Figure 7(a) is a front view showing the slot machine 100 with the front door 102 open, and Figure 7(b) is a side cross-sectional view of the slot machine 100.

[0114] Main body 101 is a box-shaped body that opens at the front. Inside main body 101, there is arranged a main board storage case 640 (see FIG. 13 , which will be described in detail later) that stores a main control board 600 (first board; details will be described later), and three reels 110 to 112 are arranged below main board storage case 640. To the side of main board storage case 640 and reels 110 to 112, i.e., on the left side as you face them, there is arranged a sub-control board storage case 220 that stores a sub-control board 650 (second board; details will be described later).

[0115] A medal payout device 180 (a device that pays out medals accumulated in a bucket) is disposed below, and a power supply device (not shown) having a power supply board and the like are disposed above the medal payout device 180, i.e., below the reels 110 to 112. The power supply device converts AC power supplied from an external source to the slot machine 100 into DC, converts it to a predetermined voltage, and supplies it to each control unit and device, such as the main control unit 300 and sub-control units 400 and 500, which will be described later. Furthermore, the power supply device is provided with a power storage circuit (e.g., a capacitor) for supplying power to predetermined components (e.g., the RAM 308 of the main control unit 300) for a predetermined period (e.g., 10 days) even after the external power supply is cut off.

[0116] An auxiliary medal storage 240 is disposed on the right side of the medal payout device 180, behind which an overflow terminal (not shown) is disposed.

[0117] The front door 102 is hinged to the left side of the main body 101 via a hinge device 276, and above the symbol display window 113, there are provided a reel front light 250 (details of which will be described later), a liquid crystal display device 157, an upper speaker 272, a performance control unit 160 that controls the liquid crystal display device 157, the speaker 272, etc. Also, below the symbol display window 113, there are provided a medal selector 170 for selecting inserted medals, a passage 265 through which medals pass when the medal selector 170 drops illegal medals, etc. into the medal tray 161, etc.

[0118] <Front reel lighting> Next, the pre-reel lighting 250 will be described with reference to FIGS. 7(a) and 7(b).

[0119] The reel front lighting 250 is a light-emitting means that illuminates (lights) the reel bands of each reel 110 to 112 (only the reel band 111a of the middle reel 111 is shown in Figure 7(b)) from the front side (front), and in this example, it is arranged above the pattern display window 113 on the back of the front door 102 so as to face the reel bands of the reels 110 to 112.

[0120] In this example, the reel front lighting 250 is configured with a plurality of LEDs capable of emitting light toward the front of the reel bands of the reels 110 to 112, and a colored transparent (in this example, milky white) lens cover placed in front of these LEDs.

[0121] If there is no lens cover for the reel front lighting, or if the lens cover is made of a colorless, transparent material, the light emitted from the LEDs may be reflected in granular form on the reel bands of the reels 110-112 (so-called "point light"), which may make the reels 110-112 look bad, or the light emitted from the LEDs may not spread well and may not be able to illuminate the entire reel band evenly, which may make the reels 110-112 less visible. Therefore, it is preferable to cover the front of the LEDs with a lens cover made of a colored, transparent material.

[0122] The relationship between the shortest distance L0 from the reel front lighting 250 to the reel band and the shortest distance L1 from the reel backlight 264 (described later) to the reel band is "shortest distance L0 < shortest distance L1", and the reel front lighting 250 is positioned closer to the reel band than the reel backlight 264.

[0123] As described above, the reel front lighting 250 is provided with a lens cover because it is prone to point light due to its close distance to the reel band. On the other hand, the reel backlight 264 is provided with a lens cover because it is closer to the reel band than the reel front lighting 250, has a distance that allows the light emitted from the LED to diffuse, and the light can be sufficiently diffused by the reflector 266 described below.

[0124] <Reel backlight> Next, the reel backlight 264 will be described with reference to FIG. 7(b) and FIG.

[0125] The slot machine 100 of this example is configured to have a left reel device (not shown) equipped with a left reel 110, a center reel device 260 (see FIG. 7(b)) equipped with a center reel 111, a right reel device (not shown) equipped with a right reel 112, and a reel frame 262 (see FIG. 7(b)) capable of accommodating these three reel devices inside.

[0126] In addition, since the structures of the left reel device and the right reel device of the slot machine 100 in this example are the same as the structure of the center reel device 260, here we will explain the center reel device 260 and omit explanations of the left reel device and the right reel device.

[0127] The middle reel device 260 is composed of a middle reel 111, a reel drive unit (not shown) that drives the middle reel 111 to rotate, a reel backlight 264 that illuminates (lights) the reel band 111a (second illuminated member) of the middle reel 111 from the rear side (back), and a reel detection unit (not shown) that detects the rotational position of the middle reel 111.

[0128] The middle reel 111 is configured with a reel band 111a on which multiple types of designs are printed at equal intervals, and a reel frame 111b that supports both sides of the reel band 111a. The reel band 111a is a flat ring-shaped member configured by bonding the longitudinal ends of a rectangular band-shaped member together.

[0129] 8(a) is a front view of the reel backlight 264, FIG. 8(b) is a side view of the reel backlight 264, and FIG. 8(c) is an external perspective view of the reel backlight 264 when the components constituting the reel backlight 264 are disassembled and viewed from the front side.

[0130] The reel backlight 264 is a light-emitting means that illuminates (illuminates) the reel bands of each reel 110 to 112 from the rear side (back surface), and in this example, is composed of a reflector 266 (second partition member), an illumination board 268 (second board) that is detachably attached to the back surface of the reflector 266, and a decorative panel 270 that is arranged on the side surface of the reflector 266.

[0131] In this example, the reflector 266 of the reel backlight 264 is formed from white plastic, but the material of the reflector 266 of the reel backlight 264 is not particularly limited, and may be metal or a material of another color.

[0132] The reflector 266 is a component that defines a space through which light from a plurality of LEDs 268a (light-emitting means) mounted on an illumination board 268 (second board) passes, and the reflector 266 has three openings 266a to 266c arranged vertically from the front side to the back side to serve as spaces through which light passes.

[0133] Six LEDs 268a (light emitting means) are arranged at positions corresponding to the openings 266a to 266c on the illumination board 268. The LEDs 268a are arranged in a light-colored region 268d (a region where a light-colored coating film is formed) on the mounting surface of the illumination board 268, where a white coating film silk is applied.

[0134] The openings 266a-266c and LEDs 268a of the reflector 266 provided in the middle reel unit 260 are arranged at positions corresponding to the symbol positions (symbol positions 4-6 described with reference to FIG. 2) to be stopped and displayed in the symbol display window 113 when the reflector 266 is attached to the middle reel unit 260. With this structure, light from the plurality of LEDs 268a (light emitting means) is irradiated onto the back surface of the reel band 111a (second irradiated member) of the middle reel 111.

[0135] The openings 266a-266c and the LED 266a of the reflector 266 provided in the left reel unit (not shown) are arranged at positions corresponding to the symbol positions (the symbol positions 1-3 described with reference to FIG. 2) to be stopped and displayed in the symbol display window 113 when the reflector 266 is attached to the left reel unit. With this structure, light from the plurality of LEDs 268a (light emitting means) is irradiated onto the back of the reel band (second irradiated member) of the left reel 110.

[0136] The openings 266a-266c and the LEDs 268a of the reflector 266 provided in the right reel unit (not shown) are arranged at positions corresponding to the symbol positions (symbol positions 7-9 described with reference to FIG. 2) to be stopped and displayed in the symbol display window 113 when the reflector 266 is attached to the right reel unit. With this structure, light from the plurality of LEDs 268a (light emitting means) is irradiated onto the back of the reel band (second irradiated member) of the right reel 112.

[0137] In this example, six LEDs 268a are arranged at positions corresponding to the openings 266a to 266c, so that the light emitted from one opening does not interfere with the light emitted from another opening, thereby enabling the light to be uniformly irradiated onto each of the multiple symbol positions on the symbol display window 113.

[0138] For example, by turning on all the LEDs 268a, all of the symbols visible to the player can be illuminated from behind. Also, by turning on some of the LEDs 268a, some of the symbols visible to the player can be illuminated from behind. Note that the number and positions of the openings and LEDs are not limited to this example.

[0139] In this example, reflector 266 has a plurality of slits (grooves) 266d to 266g provided at predetermined intervals on the bottom surface of upper opening 266a, the top and bottom surfaces of central opening 266b, and the top surface of lower opening 266c. This allows the light emitted from LED 268a to be uniformly irradiated onto the pattern located in front, improving the visibility of the pattern.

[0140] Furthermore, slit 266d provided on the underside of upper opening 266a, slit 266e provided on the top surface of central opening 266b, slit 266f provided on the bottom surface of central opening 266b, and slit 266g provided on the top surface of lower opening 266c are arranged so that the areas where the slits are formed and the areas where the slits are not formed alternate in the vertical direction (so that the positions of the slits do not coincide above and below the partitions of the openings). This structure prevents interference between light beams emitted through the slits from adjacent openings.

[0141] The reel backlight 264 is able to sufficiently and uniformly illuminate the reel band by the reflector 266 and the slits (grooves) 266d to 266g, and therefore does not have a lens cover like the reel front lighting 250, but may have a configuration with a lens cover, which allows the reel band to be illuminated uniformly, and furthermore, since the reel backlight 264 does not need to be looked directly at during reel assembly or maintenance of the gaming machine, glare on the worker can be reduced.

[0142] <Differences between the status display LED and the reel backlight> Next, differences between the state display LED 280 described with reference to FIGS. 3 to 5 and the reel backlight 264 described with reference to FIGS. 7 and 8 will be described.

[0143] First, focusing on the light-emitting means and illuminated members of the status display LED 280 and the reel backlight 264, the shortest distance L1 from the LED 268a (second light-emitting means) in the reel backlight 264 to the reel band (second illuminated member) shown in FIG. 7(b) is longer than the shortest distance L2 from the LED 286 (first light-emitting means) in the status display LED 280 to the character sheet 282 (first illuminated member) shown in FIG. 5 (L1>L2).

[0144] Next, when attention is paid to the partitioning members of the status display LED 280 and the reel backlight 264, the size (opening area) of the openings 266a to 266c (partitioned space) of the reflector 266 (second partitioning member) in the reel backlight 264 shown in FIG. 7(a) is larger than the size (opening area) of the openings 284a to 284c (partitioned space) of the reflector 280 (first partitioning member) in the status display LED 280 shown in FIG. 4.

[0145] According to this example, the shortest distance L1 from the LED 268a (second light-emitting means) in the reel backlight 264 to the reel band (second illuminated member) is longer than the shortest distance L2 from the LED 286 (first light-emitting means) in the status display LED 280 to the character sheet 282 (first illuminated member) (L1>L2), the openings 266a to 266c (compartmented space) of the reflector 266 (second partitioning member) in the reel backlight 264 are larger than the openings 284a to 284c (compartmented space) of the reflector 280 (first partitioning member) in the status display LED 280, and the LED 268a is disposed in the light-colored region 268d (region where a light-colored coating film is formed) on the mounting surface of the illumination board 268 where a white coating film silk is applied, and therefore it is possible to make the light emission of the reel band (second illuminated member) stand out while suppressing point light on the reel band (second illuminated member).

[0146] 9(a) is a front view of the LED board 288 of the status display LED 280, and FIG. 9(b) is a front view of the illumination board 268 of the reel backlight 264. As shown in FIG.

[0147] As shown in FIG. 9(a), on the LED substrate 288 (first substrate) of the status display LED 280, a plurality of LEDs 286 are arranged close together, and the irradiation range and irradiation distance to the first irradiated member (character sheet 282) are small, and the free space on the mounting surface of the LED substrate 288 is limited, so that no identification information (for example, letters indicating the component name such as "LED1" or numbers indicating the control number) for identifying the LEDs 286 mounted on the LED substrate 288 or a figure (for example, a rectangular frame) indicating the location of the LEDs 286 is printed.

[0148] On the other hand, as shown in FIG. 9(b), on the illumination board 268 (second board) of the reel backlight 264, a plurality of LEDs 268a, each of which has a large illumination range and illumination distance to the second illuminated member (reel band), are arranged at predetermined intervals, and there is a relatively large open space on the mounting surface of the illumination board 268, so that identification information 268b (in this example, letters indicating the component names such as "LED1" to "LED6" and numbers indicating the control numbers) for identifying the LEDs 268a mounted on the illumination board 268 and component marks 268c (in this example, rectangular frames) indicating the locations where the LEDs 268a are arranged are printed.

[0149] The mounting surface of the lighting board 268 is composed of a light-colored area 268d coated with white silk film, whereas the identification information 268b and the component mark 268c printed on the same mounting surface are both printed in a color different from white (cream in this example). This makes it possible to make the identification information 268b and the component mark 268c more visible, and also allows the LED 268a to be mounted in the correct location.

[0150] Furthermore, since the identification information 268b is printed in a position visible from the front side through the openings 266a to 266c (partitioned space) of the reflector 266 (second partitioning member), if a malfunction occurs in the LED 268a (light-emitting means), the identification information 268b corresponding to the LED 268a (light-emitting means) with the malfunction can be easily identified, thereby improving the convenience for game parlor staff and the ease of maintenance of the light-emitting means.

[0151] <Status indicator LED and reel backlight / Summary> As explained above, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a plurality of light-emitting means and a first board (for example, the LED board 288 shown in FIG. 4), and the plurality of light-emitting means include a first light-emitting means (for example, the LED 286 of the game information display unit 126 shown in FIG. 4) that can emit light in a first state (for example, an AT state (a state in which an operation navigation is notified), an error state (a state in which an error code is notified)), the first light-emitting means is a light-emitting means that is arranged in a first region on the mounting surface of the first board, and the first region is a region in which a dark coating film is formed (for example, the dark region 288b shown in FIG. 4 in which a black coating film resist is applied), and the dark coating film is a dark coating film that is different from green.

[0152] According to the gaming machine of this embodiment, the first light-emitting means is disposed in an area on the mounting surface of the first board where a dark coating is formed, so that it is possible to prevent a part of the first light-emitting means from being reflected by light (external light) entering from outside, making it appear as if the first light-emitting means is lit even when it is off, and it is possible to provide accurate game information to the player and avoid causing any disadvantage to the player. In addition, it is possible to make the weak lighting (ghost lighting) of the first light-emitting means due to a weak current when it is off less noticeable, and it is possible to avoid a situation where a false display misleads the player.

[0153] Gaming parlor environments vary, but if the lighting inside the parlor is bright, the lighting can make it difficult to see the displays on various displays, or they can appear to be lit even when they are not, which could lead to misinterpretation by players and gaming parlor staff.However, the gaming machine of this embodiment can prevent misinterpretation of displays due to reflections from the lighting inside the parlor.

[0154] The machine may also be provided with a stop operation means (e.g., stop buttons 137-139 shown in FIG. 1) that can stop the reels (e.g., reels 110-112 shown in FIG. 1), the first state being a state that notifies an advantageous operation mode (e.g., push order) for the stop operation means, and the first light-emitting means may be a light-emitting means that constitutes a notification means that notifies information corresponding to the advantageous operation mode.

[0155] With this configuration, it is possible to prevent the player from misunderstanding that the operation mode is being notified when it is not, and it is possible to provide the player with accurate information and avoid causing any disadvantage to the player.

[0156] The first state may be a state in which an error is notified, and the first light-emitting means may be a light-emitting means constituting a notifying means for notifying information corresponding to the error (for example, an error code).

[0157] With this configuration, it is possible to prevent the player from misunderstanding that an error has been notified when no error has been notified, and it is possible to provide the player with accurate information and avoid causing any disadvantage to the player.

[0158] Furthermore, the plurality of light-emitting means may include a second light-emitting means (for example, LED 286 of the stored number display unit 125 or the dispensed number display unit 127 shown in Figure 4) that can emit light in a second state (for example, a state in which medals are being stored, a state in which medals are being dispensed), and the second light-emitting means may be a light-emitting means that is arranged in a second region on the mounting surface of the first board, and the second region may be a region in which a light-colored coating film is formed (for example, light-colored region 288a in which a white coating film silk is applied, as shown in Figure 4), and the second region may be a region that is larger than the first region, and the second region may be a region that is formed adjacent to the first region.

[0159] Furthermore, the plurality of light-emitting means include a second light-emitting means (for example, LED 286 of stored number display unit 125 or dispensed number display unit 127 shown in Figure 4) that can emit light in a second state (for example, a state in which medals are being stored, a state in which medals are being dispensed), and the second light-emitting means is a light-emitting means that is arranged in a second region on the mounting surface of the first board, and the second region is a region in which a light-colored coating film is formed (for example, light-colored region 288a in which a white coating film silk is applied, as shown in Figure 4), and the frequency with which the second state is reached may be higher than the frequency with which the first state is reached.

[0160] With this configuration, it is possible to improve the visibility of the second light emitting means, which emits light frequently (high display update frequency), and to improve convenience for the player.

[0161] The first region may be a region sandwiched between the second region on both sides.

[0162] With this configuration, it is possible to prevent the light-emitting means arranged in the second region (region where a light-colored coating film is formed) on one side of the first region (region where a dark-colored coating film is formed) from affecting the light-emitting means arranged in the second region (region where a light-colored coating film is formed) on the other side of the first region (region where a dark-colored coating film is formed), making it easier to see the alert provided by the light-emitting means.

[0163] The light source may also include a first partitioning member (e.g., reflector 284 shown in Figures 4 and 5) and a first irradiated member (e.g., character sheet 282 shown in Figures 4 and 5), wherein the first partitioning member is a member that partitions a space through which light from the plurality of light-emitting means mounted on the first substrate passes (e.g., openings 284a to 284c shown in Figure 8(b)), the first partitioning member is fixed to the first substrate by crimping (e.g., fixed by thermal crimping portion 284d shown in Figure 5), the first irradiated member is a member that is irradiated with light from the plurality of light-emitting means mounted on the first substrate, the first irradiated member is attached to the first partitioning member, and the first substrate, the first partitioning member, and the first irradiated member may be unitized.

[0164] With this configuration, it is possible to easily replace the unitized first substrate, first partition member, and first irradiated member, as well as to assemble them into the gaming machine, thereby improving work efficiency.

[0165] The present invention also includes a second substrate (for example, the illumination substrate 268 shown in FIGS. 7(b) and 8(c)), a second partitioning member (for example, the reflector 266 shown in FIGS. 7(b) and 8(c)), and a second irradiated member (for example, the reel strip 111a shown in FIG. 7(a), a lens cover, or a panel), wherein the second substrate is a substrate on which the plurality of light-emitting means (for example, the LED 268a shown in FIG. 8(c)) are mounted, the second partitioning member is a member that partitions a space (for example, openings 266a to 266c shown in FIG. 8(b)) through which light from the plurality of light-emitting means mounted on the second substrate passes, the second irradiated member is a member that is irradiated with light from the plurality of light-emitting means mounted on the second substrate, and the shortest distance from the plurality of light-emitting means mounted on the second substrate to the second irradiated member is The distance (e.g., the shortest distance L1 shown in FIG. 7(b)) is longer than the shortest distance (e.g., the shortest distance L2 shown in FIG. 5) from the plurality of light-emitting means (e.g., the LED 286 shown in FIG. 5) mounted on the first substrate to the first irradiated member (e.g., the character sheet 282 shown in FIG. 5) (L1>L2), the partitioned space in the second partitioning member (e.g., the area of ​​the openings 266a to 266c shown in FIG. 8(b)) is larger than the partitioned space in the first partitioning member (e.g., the area of ​​the openings 284a to 284c shown in FIG. 8(b)), and the region on the mounting surface of the second substrate where the plurality of light-emitting means are arranged may be a region where a light-colored coating film (e.g., the light-colored region 268d shown in FIG. 9(b) to which white coating film silk is applied) is formed.

[0166] With this configuration, it is possible to make the light emitted from the second irradiated member stand out while suppressing point light from the second irradiated member.

[0167] Furthermore, the second substrate is a substrate that can be attached and detached to the second partition member, and identification information corresponding to each of the multiple light-emitting means on the mounting surface of the second substrate (for example, identification information 268b shown in Figure 9(b)) is displayed, and the identification information may be visible through the partitioned space in the second partition member.

[0168] With this configuration, if a malfunction occurs in the light-emitting means, the identification information corresponding to the malfunctioning light-emitting means can be easily identified, thereby improving convenience and maintainability.

[0169] <Control unit> Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to Figure 10. Note that Figure 10 shows a circuit block diagram of the control unit.

[0170] The control unit of the slot machine 100 is broadly composed of a main control unit 300 that mainly controls gameplay, a first sub-control unit 400 that mainly controls presentation in response to command signals (hereinafter simply referred to as "commands") sent by the main control unit 300, and a second sub-control unit 500 that controls various devices based on the commands sent from the first sub-control unit 400.

[0171] <Main control unit> First, we will explain the main control unit 300 of the slot machine 100. The main control unit 300 is equipped with a basic circuit 302 that controls the entire main control unit 300, and this basic circuit 302 is equipped with a CPU 304, a ROM 306 for storing control program data, lottery data used in the internal lottery for winning combinations, reel stop positions, etc., a RAM 308 for temporarily storing data, an I / O 310 for controlling the input and output of various devices, a counter timer 312 for measuring time, number of times, etc., and a WDT (watchdog timer) 314. Note that other storage devices may be used for the ROM 306 and RAM 308, and this also applies to the first sub-control unit 400 and second sub-control unit 500 described below.

[0172] The CPU 304 of this basic circuit 302 operates by receiving a clock signal with a predetermined cycle output by the crystal oscillator 315b as a system clock. Furthermore, when the power is turned on, the CPU 304 transmits frequency division data stored in a predetermined area of ​​the ROM 306 to the counter timer 312. The counter timer 312 determines an interrupt time based on the received frequency division data and transmits an interrupt request to the CPU 304 at each interrupt time. The CPU 304 monitors the sensors and transmits drive pulses in response to this interrupt request. For example, if the clock signal output by the crystal oscillator 315b is set to 8 MHz, the frequency division value of the counter timer 312 is set to 1 / 256, and the frequency division data in the ROM 306 is set to 47, the reference time for the interrupt is 256 × 47 ÷ 8 MHz = 1.504 ms.

[0173] The main control unit 300 is equipped with a random number generation circuit 316 (which is assumed to have two random number generation circuits built in) that derives a number in the range of 0 to 65535 each time it receives a clock signal output by the crystal oscillator 315a, and a start-up signal output circuit 338 that outputs a start-up signal (reset signal) when power is turned on.When a start-up signal is input from this start-up signal output circuit 338, the CPU 304 starts game control (starts the main processing of the main control unit, which will be described later).

[0174] The random number generation circuit 316 generates random numbers to be used in the basic circuit 302. The random number generation circuit 316 generates random numbers in two ways: counter mode and random number mode. In counter mode, a value that counts up (down) at a predetermined time interval is acquired and the acquired value is used as a random number. The random number mode has two further methods. In the first method, a seed value of the random number is used to perform a calculation using a predetermined function (e.g., a modulus function) and derive the result of this calculation as a random number. In the second method, a value is read from a random number table in which values ​​ranging from 0 to 65535 are randomly arranged, and the read value is used as a random number. The random number generation circuit 316 acquires irregular values ​​by utilizing white noise superimposed on signals input from various sensors 318 to the sensor circuit 320. The random number generation circuit 316 uses the value thus obtained as the initial value for a counter that counts up (down) in counter mode, as a seed for a random number, or when determining the start position for reading from the random number table.

[0175] The main control unit 300 also has a sensor circuit 320, and the CPU 304 monitors the status of various sensors 318 (bet button 130 sensor, bet button 131 sensor, bet button 132 sensor, medal acceptance sensor for medals inserted from medal insertion slot 141, start lever 135 sensor, stop button 137 sensor, stop button 138 sensor, stop button 139 sensor, settlement button 134 sensor, medal payout sensor for medals paid out from medal payout device 180, optical sensor of reel 110, optical sensor of reel 111, optical sensor of reel 112, etc.) at each interrupt time.

[0176] When the sensor circuit 320 detects the H level of the start lever sensor, it outputs a signal indicating this detection to the random number generation circuit 316. Upon receiving this signal, the random number generation circuit 316 latches the value at that timing and stores it in a register that stores random numbers to be used in the lottery.

[0177] Two medal acceptance sensors are installed in the internal passage of the medal insertion slot 141 and detect whether a medal has passed through. Two start lever 135 sensors are installed inside the start lever 135 and detect the start operation by the player. Stop button 137 sensors, stop button 138 sensors, and stop button 139 sensors are installed on each of the stop buttons 137 to 139 and detect the operation of the stop button by the player.

[0178] The bet button 130 sensor, bet button 131 sensor, and bet button 132 sensor are provided on each of the medal insertion buttons 130 to 132, and detect the insertion operation when medals electronically stored in RAM 308 are inserted as medals to be inserted into a game. The settlement button 134 sensor is provided on the settlement button 134. When the settlement button 134 is pressed once, the medals electronically stored are settled. The medal payout sensor is a sensor for detecting medals to be paid out by the medal payout device 180. Note that each of the above sensors may be a non-contact sensor or a contact sensor.

[0179] The optical sensors of reel 110, reel 111, and reel 112 are installed at predetermined positions on the mounting bases of each of reels 110 to 112, and go to L level every time a light-shielding piece provided on the reel frame passes by. When CPU 304 detects this signal, it determines that the reel has made one rotation and resets the rotational position information of the reel to zero.

[0180] The main control unit 300 is equipped with a drive circuit 322 that drives the stepping motors provided in the reel devices 110 to 112, a drive circuit 324 that drives the solenoid provided in the medal selector 170 that selects the inserted medals, a drive circuit 326 that drives the motor provided in the medal payout device 180, and a drive circuit 328 that drives various lamps 336 (winning line indicator lamp 120, notification lamp 123), the medal insertion possible indicator 124 of the status indicator LED 286, the game start indicator 121, the replay indicator 122, the medal insertion indicator 129, the number of stored medals indicator 125, the game information indicator 126, and the number of paid out medals indicator 127.

[0181] In addition, an information output circuit 334 (external centralized terminal board 248) is connected to the basic circuit 302, and the main control unit 300 outputs game information (e.g., game status) of the slot machine 100 to an information input circuit 651 provided in an external hall computer (not shown) or the like via this information output circuit 334.

[0182] The main control unit 300 also includes a voltage monitoring circuit 330 that monitors the voltage value of the power supply supplied to the main control unit 300 from a power management unit (not shown), and the voltage monitoring circuit 330 outputs a low voltage signal to the basic circuit 302 indicating that the voltage has dropped when the voltage value of the power supply is below a predetermined value (9V in this embodiment).

[0183] In addition, the main control unit 300 is equipped with an output interface for sending commands to the first sub-control unit 400, enabling communication with the first sub-control unit 400. Note that information communication between the main control unit 300 and the first sub-control unit 400 is one-way communication, and the main control unit 300 is configured to be able to send signals such as commands to the first sub-control unit 400, but is configured so that signals such as commands cannot be sent from the first sub-control unit 400 to the main control unit 300.

[0184] <Sub-controller> Next, the first sub-control unit 400 of the slot machine 100 will be described. The first sub-control unit 400 includes a basic circuit 402 that receives control commands sent by the main control unit 300 via an input interface and controls the entire first sub-control unit 400 based on these control commands. This basic circuit 402 is equipped with a CPU 404, a RAM 408 for temporarily storing data, an I / O 410 for controlling the input and output of various devices, and a counter timer 412 for measuring time, number of times, etc. The CPU 404 of the basic circuit 402 operates by receiving a clock signal with a predetermined period output by a crystal oscillator 414 as a system clock. The ROM 406 stores control programs and data for controlling the entire first sub-control unit 400, data for controlling the backlight lighting pattern and various displays, etc.

[0185] The CPU 404 transmits the frequency division data stored in a predetermined area of ​​the ROM 406 to the counter timer 412 via the data bus at a predetermined timing. The counter timer 412 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 404 for each interrupt time. The CPU 404 controls each IC and each circuit based on the timing of this interrupt request.

[0186] The first sub-control unit 400 is also provided with a sound source IC 418, which is connected to speakers 272, 277 via an output interface. The sound source IC 418 controls the sound output from the amplifier and speakers 272, 277 in response to commands from the CPU 404. An S-ROM (sound ROM) in which sound data is stored is connected to the sound source IC 418, and the sound data acquired from this ROM is amplified by the amplifier and output from the speakers 272, 277.

[0187] In addition, the first sub-controller 400 is provided with a drive circuit 422, to which various lamps 420 (upper lamps, lower lamps, side lamps 144, title panel 162 lamps, etc.) are connected via an input / output interface.

[0188] The first sub-control unit 400 also has a drive circuit 424 that drives the motor of the shutter 163, and the drive circuit 424 is connected to the shutter 163 via an output interface. This drive circuit 424 outputs a drive signal to a stepping motor (not shown) provided in the shutter 163 in response to a command from the CPU 404.

[0189] The first sub-control unit 400 is also provided with a sensor circuit 426, which is connected via an input interface to a shutter sensor 428 capable of detecting the position of the shutter 163 and an effect button sensor 430 capable of detecting the pressing operation of the effect button 156. The CPU 404 monitors the status of the shutter sensor 428 and the effect button sensor 430 at each interrupt time.

[0190] The CPU 404 also transmits and receives signals to the second sub-control unit 500 via the output interface. The second sub-control unit 500 performs various controls of the performance device 160, including display control of the performance image display device 157 (hereinafter also referred to as the "liquid crystal display device 157"). The second sub-control unit 500 may be configured with multiple control units, such as a control unit that controls the display of the liquid crystal display device 157 and a control unit that controls various performance drive devices (for example, a control unit that controls the motor drive of the shutter 163).

[0191] The second sub-control unit 500 is equipped with a basic circuit 502 that receives control commands sent by the first sub-control unit 400 via an input interface and controls the entire second sub-control unit 500 based on these control commands.This basic circuit 502 is equipped with a CPU 504, a RAM 508 for temporarily storing data, an I / O 510 for controlling the input and output of various devices, and a counter timer 512 for measuring time, number of times, etc.The CPU 504 of the basic circuit 502 operates by inputting a clock signal of a predetermined period output by a crystal oscillator 514 as a system clock.The ROM 506 stores control programs and data for controlling the entire second sub-control unit 500, data for image display, etc.

[0192] The CPU 504 transmits the frequency division data stored in a predetermined area of ​​the ROM 506 to the counter timer 512 via the data bus at a predetermined timing. The counter timer 512 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 504 for each interrupt time. The CPU 504 controls each IC and each circuit based on the timing of this interrupt request.

[0193] The second sub-control unit 500 is also provided with a VDP 516 (video display processor), which is connected to the ROM 506 and VRAM 518 via a bus. The VDP 516 reads out image data and the like stored in the ROM 506 based on signals from the CPU 504, generates a display image using the work area of ​​the VRAM 518, and displays the image on the performance image display device 157.

[0194] <Main control board> Next, the main control board 600 (first board) will be described with reference to Fig. 11. Fig. 11(a) is a plan view of the main control board 600 before the identification board 610 is separated, and Fig. 11(b) is a plan view of the main control board 600 after the identification board 610 has been separated.

[0195] The main control board 600 is an example of a "first board" according to the present invention. Therefore, the "first board" according to the present invention is not limited to the board constituting the main control unit 300, but may be a board constituting the first sub-control unit 400 or the second sub-control unit 500 described using FIG. 10, or may be any other board mounted on the gaming machine. In addition, the gaming machine may be equipped with multiple boards corresponding to the "first board."

[0196] The main control board 600 is configured to include a substrate 602 made of a rectangular plate, pattern wiring (not shown) and a solder resist layer 604 (hereinafter also referred to as "resist layer 604" and corresponding to a first resist layer) formed on one surface of the substrate 602, multiple types of components 606 mounted on one surface of the substrate 602, identification information 608 printed in a predetermined region (a region where the pattern wiring and resist layer 604 are not formed) on one surface of the substrate 602, and an identification board 610 having identification information 622 different from the identification information 608. A gap is provided from the end of the substrate 602 to the end of the resist layer 604.

[0197] According to this example, the identification information 608 is printed in an area where the pattern wiring or the resist layer 604 is not formed, so even if other information (such as the name of the component) is printed on the resist layer 604, the visibility of the identification information 608 can be improved, thereby improving convenience.

[0198] The identification information 608 of the main control board 600 is identification information that includes information that can identify the manufacturer of the gaming machine, and in this example, the name of the manufacturer of the slot machine 100 (in this example, BBB Company) and the identification number of the main control board 600 (in this example, XXX-YYY) are printed on one side of the base material 602 as the identification information 608.

[0199] The "identification information" according to the present invention may be any identification information that includes information that can identify the manufacturer of the gaming machine, and may be, for example, only the name of the manufacturer of the slot machine 100, or may be identification information that includes information such as the manufacturing date of the main control board 600 in addition to the name of the manufacturer of the slot machine 100 and the identification number of the main control board 600, or may be identification information that includes information other than characters, such as a two-dimensional code or symbol.

[0200] <Main control board / board housing recess> Next, the board accommodating recess 612 (first shape recess) of the main control board 600 will be described.

[0201] A recess 612 (first-shaped recess) having an approximately inverted U-shape when viewed from the front is formed on the right side (the short side on the right side when viewed from the front) of the main control board 600, which is large enough to accommodate the identification board 610 inside.The recess 612 is cut inward from the short side on the right side of the main control board 600.

[0202] The board accommodating recess 612 (first shape recess) is composed of two side walls 612a extending inward from the right short side of the main control board 600, and a bottom surface 612b connecting these two side walls 612a.

[0203] The width w1 of the bottom surface 612b is longer than the height h1 of the side wall 612a (w1>h1), and the direction parallel to the bottom surface 612b (the short side direction of the main control board 600) is the longitudinal direction of the board accommodating recess 612, and the direction parallel to the side wall 612a (the long side direction of the main control board 600) is the short side direction of the board accommodating recess 612.

[0204] The height h1 of the side wall 612a is slightly higher than the height h2 of the identification board 610, and the width w1 of the bottom surface 612b is slightly wider than the width w2 of the identification board 610. The entire identification board 610 is accommodated in the inner space of the board accommodating recess 612, and the bottom surface 612b of the board accommodating recess 612 and one opposing side of the identification board 610 are connected to each other via a breaking portion 616 so as to be detachable.

[0205] When the identification board 610 is accommodated in the board accommodating recess 612, its top surface (the surface opposite the board accommodating recess 612) is configured to be approximately flush with the surface on which the board accommodating recess 612 is formed (the right side surface of the main control board 600).

[0206] According to this example, the identification board 610 is accommodated in the board accommodating recess 612 of the main control board 600, and is configured so that when accommodated in this board accommodating recess 612, its upper surface is approximately flush with the right side surface of the main control board 600. This prevents the identification board 610 from coming into contact with other components, etc., when the main control board 600 is being transported, etc., thereby improving convenience.

[0207] The "first-shaped recess" according to the present invention is not limited to the substrate accommodating recess 612 according to this example. For example, the width w1 of the bottom surface 612b is shorter than the height h1 of the side wall 612a (w1

[0208] <Main control board / Identification board> Next, the identification board 610 of the main control board 600 will be described.

[0209] The identification board 610 is a board on which no pattern wiring or resist layer is formed, and is composed of a base material 620 consisting of a rectangular plate-like body, and identification information 622 printed in a predetermined area on one side of the base material 620 (an area on which no pattern wiring or resist layer is formed).

[0210] The identification information 622 of the identification board 610 is identification information that includes information that can identify the manufacturer of the gaming machine, and in this example, the name of the manufacturer of the slot machine 100 (in this example, AAA Company) and the identification number of the main control board 600 (in this example, XXX-YYY) are printed on one side of the base material 620 as the identification information 622.

[0211] The "identification information" according to the present invention may be any identification information that includes information that can identify the manufacturer of the gaming machine, and may be, for example, only the name of the manufacturer of the slot machine 100, or may be identification information that includes information such as the date of manufacture of the main control board 600 in addition to the name of the manufacturer of the slot machine 100 and the identification number of the main control board 600, or may be information other than characters such as a two-dimensional code or symbol.

[0212] <Main control board / fracture area> Next, the breakage portion 616 of the main control board 600 will be described.

[0213] ​As shown in Figure 11(a), the breaking portion 616 is a portion where multiple slits (perforations) are formed at predetermined intervals at the connecting portion between the base material 602 of the main control board 600 and the base material 620 of the identification board 610, and is a portion that makes it easy to separate the identification board 610 from the base material 602 of the main control board 600.

[0214] By cutting the breaking portion 616 by hand (or using a tool such as pliers), the identification board 610 can be separated from the base material 602 of the main control board 600, as shown in Figure 11(b).

[0215] As explained using Figure 11(a), before the identification board 610 is separated, the main control board 600 has two types of identification information: identification information 618 of the main control board 600 (name of the manufacturer of the slot machine 100: BBB Company) and identification information 622 of the identification board 610 (name of the manufacturer of the slot machine 100: AAA Company), so the manufacturer of the gaming machine cannot be identified.

[0216] However, as shown in FIG. 11(b), by separating the identification board 610 from the base material 602 of the main control board 600, only the identification information 618 (name of the manufacturer of the slot machine 100: BBB Company) remains on the main control board 600, and the main control board 600 (first board) is a board in which the manufacturer of the gaming machine (in this example, BBB Company) can be identified by cutting the breaking portion 616.

[0217] If a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company will increase manufacturing costs, but in this example, one or more company names can be printed on one circuit board product, and when each affiliated company manufactures and assembles the gaming machine, they can choose to keep only their own company name or delete unnecessary company names, thereby reducing manufacturing costs and providing gaming machines that do not cause problems during assembly or inspection.

[0218] Note that the shape of the "breaking part" according to the present invention is not limited to this example. For example, there may be only one slit, or instead of the slit (perforation), a V-cut may be adopted. That is, any part that can separate the identification substrate from the base material of the main control substrate is acceptable.

[0219] <Main control board / Adapter accommodation recess> Next, the adapter accommodation recess 614 (the recess of the second shape) of the main control board 600 will be described.

[0220] On the left side surface of the main control board 600 (the short side on the left side in the front view), there is a recess having a size capable of accommodating one or more adapters 624 inside, and an adapter accommodation recess 614 (the recess of the second shape) having a substantially U-shaped cross-section in the front view, which is cut inward from the short side on the left side of the main control board 600, is formed.

[0221] The adapter accommodation recess 614 (the recess of the second shape) is composed of two side walls 614a extending inward from the short side on the left side of the main control board 600 and a bottom surface 614b connecting the two side walls 614a.

[0222] The width w3 of the bottom surface 614b is longer than the height h3 of the side wall 614a (w3 > h3). The direction parallel to the bottom surface 614b (the short side direction of the main control board 600) is the longitudinal direction of the adapter accommodation recess 614, and the direction parallel to the side wall 614a (the longitudinal direction of the main control board 600) is the short side direction of the adapter accommodation recess 614.

[0223] On the bottom surface 614b of the adapter accommodation recess 614, two adapters 624 to which connectors such as optical fibers can be connected are arranged at a predetermined interval.

[0224] Note that the "recess of the second shape" according to the present invention is not limited to the adapter accommodation recess 614 according to this example. For example, the width w3 of the bottom surface 614b may be shorter than the height h3 of the side wall 614a (w3 < h3), or the width w3 of the bottom surface 614b may be the same as the height h3 of the side wall 614a (w3 = h3), or it may have a shape other than a rectangular shape (such as a curved surface shape).

[0225] <Main control board / Board accommodation recess and adapter accommodation recess> When comparing the shapes of the board accommodation recess 612 (recess of the first shape) and the adapter accommodation recess 614 (recess of the second shape) on the main control board 600, as shown in Fig. 11(b), the height h1 of the side wall 612a of the board accommodation recess 612 is higher than the height h3 of the side wall 614a of the adapter accommodation recess 614 (h1 > h3), the width w1 of the bottom surface 612b of the board accommodation recess 612 is narrower than the width w3 of the bottom surface 614b of the adapter accommodation recess 614 (w1 < w3), and the board accommodation recess 612 and the adapter accommodation recess 614 have different shapes from each other.

[0226] According to this example, since it has the feature point of having recesses with different shapes, it becomes easy to identify the board, and it is possible to correctly recognize the orientation of the board, improving the workability during installation of the board and preventing installation mistakes of the board.

[0227] In the manufacturing process of the game table, the board products are covered with various board cases and installed, fixed, and attached inside the game table. However, many board products have similar outer shapes, and installation mistakes may occur during the manufacturing and assembly of the game table, or even if no installation mistakes occur, the installer may be confused about which board to install, wasting working time. According to this example, it is easier to distinguish the boards, simplifying the process during the manufacturing and assembly of the game table.

[0228] Also, the height h1 of the side wall 612a of the board accommodation recess 612 (recess of the first shape) is higher than the height h3 of the side wall 614a of the adapter accommodation recess 614 (recess of the second shape) (h1 > h3), and the bottom surface 612b of the board accommodation recess 612 (recess of the first shape) is located more inward of the main control board 600 than the bottom surface 614b of the adapter accommodation recess 614 (recess of the second shape). Therefore, it is easier to cut the identification board 610 accommodated in the board accommodation recess 612 (recess of the first shape), improving the workability.

[0229] Next, when attention is paid to the positional relationship between the substrate accommodating recess 612 (recess of first shape) of the main control substrate 600 and the resist layer 604 (first resist layer), and the positional relationship between the adapter accommodating recess 614 (recess of second shape) and the resist layer 604 (first resist layer), as shown in Figure 11 (b), the shortest distance x1 from the bottom surface 612b (fracture surface of the first shape) of the substrate accommodating recess 612 to the end of the resist layer 604 is configured to be longer than the shortest distance x2 from the bottom surface 614b of the adapter accommodating recess 614 to the end of the resist layer 604 (x1 > x2).

[0230] In other words, the main control board 600 is configured so that the shortest distance x1 between the board accommodating recess 612 and the resist layer 604 in the first direction (longitudinal direction of the main control board 600) is longer than the shortest distance x2 between the adapter accommodating recess 614 and the resist layer 604 in the first direction (longitudinal direction of the main control board 600) (x1>x2).

[0231] According to this example, the shortest distance x1 from the bottom surface 612b (fracture surface of the first shape) of the substrate accommodating recess 612 (recess of the first shape) of the main control board 600 to the resist layer 604 (first resist layer) is longer than the shortest distance x2 from the bottom surface 614b of the adapter accommodating recess 614 (recess of the second shape) to the resist layer 604 (first resist layer) (x1>x2). Therefore, a clearance (work space) from the substrate accommodating recess 612 (recess of the first shape) to the resist layer can be secured, making it easier to cut the fracture portion 616 formed in the substrate accommodating recess 612 (recess of the first shape), improving workability. In addition, even when performing cutting work by hooking fingers around the periphery of the substrate accommodating recess 612 (recess of the first shape) or using a tool, it is possible to prevent fingers or tools from coming into contact with the resistor layer or pattern wiring, thereby preventing damage to the main control board.

[0232] Also, in this way, by making the shortest distance x1 from the break portion 616 to the end of the resist layer 604 at a location where the break portion 616 is not provided (for example, the adapter accommodation recess 614 (the recess of the second shape)) longer than the shortest distance x2 to the end of the resist layer 604 at a location where the break portion 616 is provided, it is possible to make it difficult for cracks to occur in the resist layer and the pattern wiring due to stress and strain during cutting from the break portion 616.

[0233] Also, in this example, in order to make it difficult for cracks to occur in the resist layer and the pattern wiring due to stress and strain during cutting from the break portion 616, as shown in FIG. 11(b), the shortest distance x1 from the bottom surface 612b (the fracture surface of the first shape) of the substrate accommodation recess 612 to the end of the resist layer 604 is configured to be longer (x1>z1) than the shortest distance z1 from one of the long sides of the main control substrate 600 (the long side itself can also be said to be the cross-section of the substrate) to the end of the resist layer 604. However, in order to secure a clearance (working space) from the substrate accommodation recess 612 (the recess of the first shape) to the resist layer 604, the shortest distance x1 from the bottom surface 612b (the fracture surface of the first shape) of the substrate accommodation recess 612 to the end of the resist layer 604 may be configured to be shorter (x1<z1) than the shortest distance z1 from one of the long sides of the main control substrate 600 to the end of the resist layer 604. Such a configuration is not limited to this embodiment and can also be applied to a substrate that does not have a recess of the second shape.

[0234] Also, in this example, in order to make it difficult for cracks to occur in the resist layer and the pattern wiring due to the stress and strain during cutting from the break portion 616, as shown in FIG. 11(b), the shortest distance x1 from the bottom surface 612b (the fracture surface of the first shape) of the substrate accommodation recess 612 to the end of the resist layer 604 is configured to be longer than the shortest distance z2 from one of the short sides of the main control substrate 600 to the end of the resist layer 604 (x1 > z2). However, in order to secure a clearance (working space) from the substrate accommodation recess 612 (the recess of the first shape) to the resist layer 604, the shortest distance x1 from the bottom surface 612b (the fracture surface of the first shape) of the substrate accommodation recess 612 to the end of the resist layer 604 may be configured to be shorter than the shortest distance z2 from one of the short sides of the main control substrate 600 (the short side itself can also be said to be the cross section of the substrate) to the end of the resist layer 604 (x1 < z2). Such a configuration is not limited to this embodiment and can also be applied to a substrate without the recess of the second shape.

[0235] Also, in this example, the shortest distance y1 from the side wall 612a of the substrate accommodation recess 612 (the recess of the first shape) of the main control substrate 600 to the end of the resist layer 604 (the first resist layer) is configured to be longer than the shortest distance y2 from the side wall 614a of the adapter accommodation recess 614 (the recess of the second shape) to the end of the resist layer 604 (the first resist layer) (y1 > y2).

[0236] In other words, the shortest distance y1 in the second direction (the short side direction of the main control substrate 600) between the substrate accommodation recess 612 and the resist layer 604 is configured to be longer than the shortest distance y2 in the second direction (the short side direction of the main control substrate 600) between the adapter accommodation recess 614 and the resist layer 604 (y1 > y2).

[0237] According to this example, the shortest distance y1 from the side wall 612a of the substrate accommodating recess 612 (recess having a first shape) of the main control board 600 to the resist layer 604 (first resist layer) is longer than the shortest distance y2 from the side wall 614a of the adapter accommodating recess 614 (recess having a second shape) to the resist layer 604 (first resist layer) (y1>y2). Therefore, a clearance (work space) from the substrate accommodating recess 612 (recess having a first shape) to the resist layer can be secured, making it easier to cut the breaking portion 616 formed in the substrate accommodating recess 612 (recess having a first shape), improving workability. In addition, even when performing cutting work by hooking fingers around the periphery of the substrate accommodating recess 612 (recess having a first shape) or using a tool, it is possible to prevent fingers or tools from coming into contact with the resistor layer or pattern wiring, thereby preventing damage to the main control board.

[0238] Furthermore, by making the shortest distance y1 to the end of the resist layer 604 at a location that has the break portion 616 longer than the shortest distance y2 to the end of the resist layer 604 at a location that does not have the break portion 616 (for example, the adapter accommodating recess 614 (recess of the second shape)), it is possible to make it less likely that cracks will occur in the resist layer or pattern wiring due to stress or distortion when cutting from the break portion 616.

[0239] In this example, the shortest distance from the board accommodating recess 612 to the resist layer 604 is longer than the shortest distance from the adapter accommodating recess 614 to the resist layer 604 in both the first direction (longitudinal direction of the main control board 600) and the second direction (shortitudinal direction of the main control board 600). However, the present invention is not limited to this and may be applied to only one of the first direction (longitudinal direction of the main control board 600) and the second direction (shortitudinal direction of the main control board 600).

[0240] <Main control board / components> Next, the components 606 mounted on the main control board 600 will be described.

[0241] The components 606 mounted on the main control board 600 include the adapter 624 arranged in the adapter accommodating recess 614 described above, as well as passive components 606a (606a1, 606a2) such as resistors, capacitors, and coils, a connector 606b, an IC 606c, and the like.

[0242] In the example shown in FIG. 11(b), a plurality of passive components 606a (606a1, 606a2), an IC 606c, etc. are disposed near the board accommodating recess 612 of the main control board 600.

[0243] The longitudinal direction of one passive component 606a1 (first passive component) among the multiple passive components 606a is the same as the longitudinal direction of the substrate accommodating recess 612, and the longitudinal direction of one passive component 606a2 (second passive component) among the multiple passive components 606a is a direction different from the longitudinal direction of the substrate accommodating recess 612 and is a direction perpendicular to the longitudinal direction of the substrate accommodating recess 612 (recess of first shape).

[0244] According to this example, the longitudinal direction of one passive component 606a1 (first passive component) of the multiple passive components 606a is the same as the longitudinal direction of the substrate accommodating recess 612 (recess with a first shape) (the longitudinal direction of the identification substrate 610). Therefore, the effect of stress applied in the longitudinal direction of the substrate accommodating recess 612 (recess with a first shape) when cutting the breaking portion 616 on the passive component 606a1 (first passive component) mounted on the main control substrate 600 (first substrate) can be reduced, and damage to the passive component 606a1 (first passive component) can be prevented.

[0245] 11(b), a plurality of passive components 606a (606a1, 606a2), an IC 606c, etc. are also disposed near the adapter accommodating recess 614 of the main control board 600.

[0246] These passive components are axial components with leads extending from both ends of the main body as shown in Fig. 11. Furthermore, in this embodiment and the modified examples described below, the positional relationship of the passive components is described, but this is not limiting, and the passive components may be axial components included in passive components, or control ICs included in active components, and include components that have a longitudinal direction and a lateral direction.

[0247] Here, when focusing on the positional relationship between the substrate accommodating recess 612 and the passive component 606a1, and the positional relationship between the adapter accommodating recess 614 and the passive component 606a2, the shortest distance x3 from the substrate accommodating recess 612 to the passive component 606a1 is configured to be longer than the shortest distance x4 from the adapter accommodating recess 614 to the passive component 606a2 (x3>x4).

[0248] According to this example, the shortest distance x3 from the substrate accommodating recess 612 (recess having a first shape) to the passive component 606a1 (first passive component) is longer than the shortest distance x4 from the adapter accommodating recess 614 (recess having a second shape) to the passive component 606a2 (second passive component) (x3 > x4). This ensures a clearance (work space) from the substrate accommodating recess 612 (recess having a first shape) to the passive component 606a1 (first passive component). This makes it easier to cut the breaking portion 616 formed in the substrate accommodating recess 612 (recess having a first shape), improving workability. In addition, even when a cutting operation is performed by placing a finger around the periphery of the substrate accommodating recess 612 (recess having a first shape) or by using a tool, it is possible to prevent the finger or tool from coming into contact with the passive component 606a1 (first passive component). This makes it possible to prevent damage to the passive component 606a1 (first passive component).

[0249] Note that the shortest distance x3 from the substrate accommodation recess 612 to the passive component 606a1 may be configured to be shorter than the shortest distance x4 from the adapter accommodation recess 614 to the passive component 606a2 (x3 < x4). With such a configuration, for the component closer to the end portion having the breakage portion, the longitudinal direction of the component is orthogonal to the direction in which stress is applied during cutting, so that breakage of the component can be prevented.

[0250] Also, the longitudinal direction of the substrate accommodation recess 612 and the longitudinal direction of the passive component 606a2 are different directions, and the shortest distance x3' from the substrate accommodation recess 612 to the passive component 606a2 is configured to be longer than the shortest distance x3 from the substrate accommodation recess 612 to the passive component 606a1 (x3' > x3). Also, these shortest distances are such that "x3 < x4 < x3'", and it can be seen from FIG. 11 that the shortest distance α from the substrate accommodation recess 612 to the passive component 606a2 near the adapter accommodation recess 614 passes through a longer distance, and the component parallel to the stress direction applied to the substrate is arranged at a location far from the breakage portion. Note that the shortest distance x3' is the distance of a line parallel to the long side of the substrate on the virtual extension line of the bottom surface 612b, but it may also be the distance on an oblique line from the substrate accommodation recess 612 toward the passive component 606a2.

[0251] According to this example, the longitudinal direction of the passive component 606a2 (second passive component) is different from the direction of the substrate accommodation recess 612 (first-shaped recess), and the passive component 606a2 (second passive component) is liable to be affected by the stress applied in the longitudinal direction of the substrate accommodation recess 612 (first-shaped recess) when cutting the breakage portion 616. However, by arranging the passive component 606a2 (second passive component) at a position farther from the substrate accommodation recess 612 (first-shaped recess) than the passive component 606a1 (first passive component), breakage of the passive component 606a2 (second passive component) can be prevented.

[0252] In other words, if the direction in which stress is applied to the board when breaking portion 616 is cut (the longitudinal direction of main control board 600 in Figure 11) is the same as the longitudinal direction of the component, damage to the component can be prevented by placing the component away from breaking portion 616.

[0253] <Main control board / fracture surface> Next, the cutaway surface of main control board 600 will be described.

[0254] The outer edges of the substrate 602 of the main control board 600 and the outer edges of the substrate 620 of the identification board 610 are formed with burrs (not shown; hereinafter, may be referred to as "molding burrs") caused by breakage due to router processing or the like when molding each board, and the main control board 600 (first board) and the identification board 610 are each boards having fracture surfaces (third-shaped fracture surfaces) with molding burrs.

[0255] 11(b), when the identification board 610 is separated from the base material 602 of the main control board 600, a burr 632 (hereinafter, sometimes referred to as a "fracture burr") that occurs when the fracture portion 616 is fractured (separated) into two is formed (remains) on the base material 602 of the main control board 600 and the base material 620 of the identification board 610. That is, after separation, the main control board 600 and the identification board 610 each have a fracture surface (a fracture surface with a first shape) with the fracture burr 632, in addition to a fracture surface (a fracture surface with a third shape) with the molding burr.

[0256] The burr 632 at the time of breaking is a burr that remains when the breaking portion 616 is broken (separated) into two by a slit (perforation), and is composed of a plurality of convex portions 632a (first convex portions). The convex portions 632a of the burr at breaking 632 are burrs with larger irregularities than the burr at the time of molding, and the fracture surface on which the burr at the time of molding has occurred (fracture surface of the third shape) has rougher irregularities (larger irregularities) than the fracture surface on which the burr at breaking 632 has occurred (cross section of the first shape).

[0257] The fracture surface where the burr 632 occurred during fracture (fracture surface of the first shape) is a fracture surface that remains on the main body side of the main control board 600 when the identification board 610 is separated from the base material 602 of the main control board 600, and is therefore a fracture surface that is located more inward on the main control board 600 than the fracture surface where the burr occurred during molding (fracture surface of the third shape).

[0258] According to this example, the fracture surface where burr 632 occurred (fracture surface of the first shape) is located more inward than the fracture surface where burr occurred during molding (fracture surface of the third shape), so a clearance (work space) can be secured from the recess of the first shape to the resist layer, making it easier to cut the fractured portion formed in the recess of the first shape and improving workability. Also, because the rough fracture surface is located inside the main control board, safety can be improved compared to when the rough fracture surface is exposed outside the main control board.

[0259] <Sub-control board (second board)> Next, the sub-control board 650 (second board) will be described with reference to Fig. 12. Fig. 12 is a plan view of the sub-control board 650.

[0260] The sub-control board 650 is an example of a "second board" according to the present invention. Therefore, the "second board" according to the present invention is not limited to the board constituting the first sub-control unit 400, but may be a board constituting the main control unit 300 or the second sub-control unit 500 described using FIG. 10, or may be any other board mounted on the gaming machine. In addition, the gaming machine may be equipped with multiple boards corresponding to the "second board."

[0261] The sub-control board 650 is composed of a base material 652 consisting of a rectangular plate-shaped body, pattern wiring (not shown) and a resist layer 654 (second resist layer) formed on one side of the base material 652, and multiple types of components 656 mounted on one side of the base material 652.

[0262] <Sub-control board / fracture surface> Next, the fractured surface of the sub-control board 650 will be described.

[0263] Burrs 658 (hereinafter sometimes referred to as "molding burrs 658") are formed on part of each longitudinal and lateral side of the base material 652 of the sub-control board 650 due to breakage caused by router processing or the like when molding the base material 652, and the sub-control board 650 (second board) is a board having a first fracture surface 650a (a fracture surface of a second shape) on which the molding burrs 658 have been formed, and a second fracture surface 650b on which the molding burrs 658 have not been formed.

[0264] The sub-control board 650 is a board that does not have a break portion that corresponds to the identification board 610 that the main control board 600 has, or that corresponds to the break portion 616 that the main control board 600 has.

[0265] Molding burr 658 of sub-control board 650 is a burr caused by breakage due to router processing or the like when molding base material 652 of sub-control board 650, and is composed of multiple convex portions 658a (second convex portions). This molding burr 658 is a burr with smaller irregularities than fracture burr 632 (a burr that remains when fracture portion 616 of main control board 600 is broken (separated) into two by a slit (perforation)) of main control board 600 (first board) described using Figure 11, and fracture surface 660 (fracture surface of the second shape) where molding burr 658 has occurred has finer irregularities (smaller irregularities) than the fracture surface (cross section of the first shape) where fracture burr 632 has occurred.

[0266] Here, when we pay attention to the positional relationship between the substrate accommodating recess 612 of the main control board 600 and the resist layer 604, and the positional relationship between the first fracture surface 650a of the sub-control board 650 and the resist layer 654, the shortest distance x1 from the bottom surface 612b of the substrate accommodating recess 612 of the main control board 600 to the resist layer 604, as shown in Figure 11(b), is configured to be longer than the shortest distance x5 from the first fracture surface 650a of the sub-control board 650 to the resist layer 654, as shown in Figure 12 (x1>x5).

[0267] According to this example, the shortest distance x1 from the bottom surface 612b (fracture surface of the first shape) of the substrate accommodating recess 612 (recess of the first shape) of the main control board 600 to the resist layer 604 (first resist layer) is longer than the shortest distance x5 from the first fracture surface 650a (fracture surface of the second shape) of the sub-control board 650 to the resist layer 654 (second resist layer) (x1>x5). Therefore, a clearance (work space) from the substrate accommodating recess 612 (recess of the first shape) to the resist layer can be secured, making it easier to cut the fracture portion 616 formed in the substrate accommodating recess 612 (recess of the first shape). This improves workability. Furthermore, even when cutting work is performed by placing fingers around the periphery of the substrate accommodating recess 612 (recess of the first shape) or using a tool, it is possible to prevent fingers or tools from coming into contact with the resistor layer or pattern wiring, thereby preventing damage to the main control board.

[0268] 12, the shortest distance x5 from first fracture surface 650a of sub-control board 650 to resist layer 654 is longer than the shortest distance x6 from second fracture surface 650b to resist layer 654 (x5>x6). With this configuration, cracks are less likely to occur in the resist layer when separating a discarded board or adjacent boards during board molding.

[0269] <Main board storage case> Next, the configuration of the main board storage case 640 (642, 644) will be described with reference to FIGS.

[0270] Figure 13 is an exploded oblique view showing the main board storage case 640 and the main control board 600, and Figure 14(a) is a plan view of the main board storage case 640 housing the main control board 600, viewed from the board housing body 642 side.

[0271] FIG. 14(b) is a cross-sectional view taken along line AA in FIG. 14(a), and FIG. 14(c) is a cross-sectional view showing the structure of a conventional substrate corresponding to FIG. 14(b).

[0272] As shown in Figure 13, the main board storage case 640 is a box-shaped body formed by combining a board storage body 642 (storage body) having a roughly rectangular, square-dish-shaped bottom surface and a lid body 644 arranged to cover the internal space of this board storage body 642.

[0273] Main control board 600 is housed in the internal space of main board storage case 640, fixed to board storage body 642 with screws 646. Board storage body 642 and lid 644 are each made of translucent resin, and main control board 600 housed inside main board storage case 640 can be seen from the outside through main board storage case 640.

[0274] Gate-shaped hinge portions 642b are provided in two locations on the lower edge of the substrate housing body 642. Hook-shaped hook portions 644a that engage with these hinge portions 642b are provided in two locations on the lower edge of the lid body 644, and locking tongue pieces 644b that lock with the upper edge of the substrate housing body 642 are provided on both left and right ends of the upper edge.

[0275] Therefore, when assembling the main board storage case 640, first, the hook portion 644a of the lid body 644 is engaged with the hinge portion 642b of the board container 642, and then the lid body 644 is swung around the hinge portion 642b to combine the board container 642 and the lid body 644, and the locking tongue 644b of the lid body 644 is engaged with the locking hole on the upper edge of the board container 642, thereby fixing the lid body 644 to the board container 642.

[0276] As shown in Figure 13, two ribs 642a (convex portions) are formed on the left side of the inner space of the board accommodating body 642 when viewed from the front, at positions corresponding to the adapter accommodating recess 614 (second-shaped recess) of the main control board 600, and as shown in Figure 14(a), when the main control board 600 is accommodated in the board accommodating body 642, these two ribs 642a are each fitted into two side walls 614a of the adapter accommodating recess 614 (second-shaped recess) of the main control board 600.

[0277] According to this example, since the main board storage case 640 includes ribs 642a that can be fitted (abutted) into the adapter accommodation recess 614 (recess of the second shape) of the main control board 600 (first board), when accommodating the main control board 600 (first board), the main control board 600 (first board) can be accommodated in the correct position and with the correct orientation, preventing mistakes in board installation and the like. Moreover, after accommodating the main control board 600 (first board), the main control board 600 (first board) can be securely held, so that rattling of the main control board 600 (first board) during insertion and removal of the connector from the adapter 624 and the like can be suppressed.

[0278] Also, as described above, the board accommodation recess 612 and the adapter accommodation recess 614 of the main control board 600 have different shapes, and the width w1 of the bottom surface 612b of the board accommodation recess 612 is narrower than the width w3 of the bottom surface 614b of the adapter accommodation recess 614 (w1 < w3). Therefore, the two ribs 642a are structured such that they cannot be fitted into the two side walls 614a of the board accommodation recess 612 of the main control board 600.

[0279] According to this example, since the two ribs 642a of the board storage body 642 (storage body) cannot be fitted into the two side walls 614a of the board accommodation recess 612 (recess of the first shape) of the main control board 600, when accommodating the main control board 600, the main control board 600 can be accommodated in the correct position and with the correct orientation, preventing mistakes in board installation and the like.

[0280] On the other hand, as shown in FIG. 13, at the position corresponding to the board accommodation recess 612 (recess of the first shape) of the main control board 600 on the right side in the front view of the inner space of the board storage body 642, no ribs or the like are provided. As shown in FIG. 14(a), in the state where the main control board 600 is accommodated in the board storage body 642, voids (spaces where nothing is provided, hereinafter also referred to as "void regions") are formed above and below the board accommodation recess 612 (recess of the first shape) of the main control board 600.

[0281] Therefore, as shown in Figure 14(b), the components (e.g., IC 606c) arranged on the main control board 600 can be seen through the board accommodating recess 612 from either side of the board accommodating body 642 and the lid body 644 of the main board accommodating case 640.

[0282] The IC 606c is a component arranged near the substrate accommodating recess 612 (recess of a first shape). The IC 606c is also a component whose chip body can be fitted into a socket. Although the short side of the IC 606c is visible from the gap region, the IC 606c may be arranged vertically so that it is visible from the long side. In this case, the substrate accommodating recess 612 (recess of a first shape) may be formed so that the entire long side of the IC 606c is visible from the gap region, or the IC 606c may be arranged so that it is visible from a part of the long side of the IC 606c.

[0283] Furthermore, other components may not be disposed between the IC 606c and the substrate accommodating recess 612 (recess of the first shape), which prevents the IC 606c from being obstructed from being visible from the gap region. If other components are disposed between the IC 606c and the substrate accommodating recess 612 (recess of the first shape), the other components should be shorter than the IC 606c to ensure visibility from the gap region. In this case, although the other components may be damaged when the identification substrate 610 is broken, damage to the IC 606c can be prevented, and the damaged other components can be used to identify the substrate as defective.

[0284] According to this example, the board can be easily viewed, making it easier to detect unauthorized components when they are attached to the board, and it is also possible to check the components mounted on the board while they are contained in the container, thereby improving maintenance and workability.

[0285] <Main control board / Summary> As described above, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (for example, the main control board 600 shown in FIG. 11), wherein the first board is a board having a recess of a first shape (for example, the board accommodating recess 612 shown in FIG. 11), and the first board is a board having a recess of a second shape (for example, the adapter accommodating recess 614 shown in FIG. 11), and the recess of the first shape and the recess of the second shape are different shapes.

[0286] According to the gaming machine of this embodiment, the board (first board) has a feature of having recesses of different shapes, which makes it easy to identify the board and enables the orientation of the board to be correctly recognized, thereby improving workability when installing the board and preventing mistakes in installing the board, etc. In this way, it is possible to provide a gaming machine in which mistakes in installation, etc. are reduced.

[0287] In the manufacturing process of gaming machines, the finished circuit board products are covered with various circuit board cases and then installed, fixed, and attached inside the gaming machine. However, since many circuit board products have similar external shapes, installation errors can occur during the manufacturing and assembly of the gaming machine, or, even if they do not result in an installation error, workers can be confused about which circuit board to install, resulting in wasted work time. However, the gaming machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the manufacturing and assembly process of the gaming machine.

[0288] The housing may also include a container (e.g., substrate container 642 shown in FIG. 14(b)), which is capable of storing the first substrate, and when the first substrate is stored in the housing, a component (e.g., IC 606c shown in FIG. 14(b)) arranged on the first substrate may be visible through a recess of the first shape (e.g., substrate storage recess 612 shown in FIG. 14(b)).

[0289] With this configuration, the board (first board) can be easily seen, making it easier to find any illegal components that have been installed, and the components mounted on the board can be checked while they are housed in the housing, improving maintainability and workability. In this way, a gaming machine with improved maintainability can be provided.

[0290] The container may also include a container (e.g., substrate container 642 shown in FIG. 14(a)), which is capable of storing the first substrate, and which has a convex portion therein (e.g., rib 642a shown in FIG. 14(a)), and the convex portion may be a portion that can fit into the recess of the second shape (e.g., adapter accommodating recess 614 shown in FIG. 14(a)), but cannot fit into the recess of the first shape (e.g., substrate accommodating recess 612 shown in FIG. 14(a)).

[0291] With this configuration, when storing the board (first board), the board can be stored in the correct position and in the correct orientation, preventing operational errors, and after storing the board, the board can be securely held, reducing rattle of the board when inserting and removing connectors, etc. In this way, it is possible to provide a gaming machine with improved operability during assembly and inspection.

[0292] Furthermore, the first substrate is a substrate that allows one manufacturer of the gaming machine to be identified by cutting a break portion (for example, break portion 616 shown in Figure 11(a)), and the recess of the first shape may be the portion where the break portion is formed.

[0293] If a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company would increase manufacturing costs, but with this configuration, one or more company names can be printed on one circuit board product, and when each affiliated company manufactures and assembles the gaming machine, they can choose to keep only their own company name or delete unnecessary company names, thereby reducing manufacturing costs and providing gaming machines that do not have any problems during assembly or inspection.

[0294] Furthermore, the first substrate may be a substrate having a plurality of components (e.g., passive components 606 such as resistors, capacitors, and coils shown in FIG. 11), one of the plurality of components being a first component (e.g., passive component 606a1 shown in FIG. 11(b)) arranged near the recess of the first shape, and the longitudinal direction of the recess of the first shape (e.g., substrate accommodating recess 612 shown in FIG. 11(b)) and the longitudinal direction of the first component may be the same direction.

[0295] With this configuration, the effect of stress applied in the longitudinal direction of the recess of the first shape when cutting the breaking portion on the first passive component mounted on the first substrate can be reduced, and damage to the first passive component can be prevented. In this way, it is possible to provide a gaming machine in which defects due to component damage are suppressed.

[0296] Furthermore, the first substrate may be a substrate having a plurality of components (e.g., passive components 606 such as resistors, capacitors, and coils shown in FIG. 11, elongated components, and components with terminals protruding from their main bodies), one of the plurality of components may be a first component arranged near the recess of the first shape (e.g., passive component 606a1 shown in FIG. 11(b)), and one of the plurality of components may be a second component arranged near the recess of the second shape (e.g., passive component 606a2 shown in FIG. 11(b)), and the shortest distance from the recess of the first shape to the first component (e.g., shortest distance x3 shown in FIG. 11(b)) may be longer than the shortest distance from the recess of the second shape to the second component (e.g., shortest distance x4 shown in FIG. 11(b)).

[0297] With this configuration, a clearance (work space) from the recess of the first shape to the first passive component can be secured, making it easier to cut the fracture portion formed in the recess of the first shape and improving workability. In addition, even when the cutting work is performed by placing a finger around the periphery of the recess of the first shape or by using a tool, the finger or tool can be prevented from coming into contact with the first passive component, thereby preventing damage to the first passive component, etc. In this way, it is possible to provide an amusement machine that suppresses malfunctions due to component damage and improves worker safety.

[0298] Furthermore, the longitudinal direction of the recess of the first shape and the longitudinal direction of the second part may be different directions, and the shortest distance from the recess of the first shape to the second part (for example, the shortest distance α shown in Figure 11(b)) may be longer than the shortest distance from the recess of the first shape to the first part (for example, the shortest distance x3 shown in Figure 11(b)).

[0299] With this configuration, the longitudinal direction of the second passive component is different from the direction of the recess of the first shape, and the second passive component is susceptible to the stress applied in the longitudinal direction of the recess of the first shape when the breaking portion is cut, but by arranging the second passive component at a position farther from the recess of the first shape than the first passive component, it is possible to prevent damage to the second passive component. In this way, it is possible to provide a gaming machine in which defects due to component damage are suppressed.

[0300] Furthermore, the first substrate may be a substrate having a resist (e.g., resist layer 604 shown in FIG. 11), and the first substrate may be a substrate having identification information (e.g., identification information 608 shown in FIG. 11) displayed in a predetermined area, the identification information being identification information including information that can identify one manufacturer of the gaming machine, and the predetermined area may be an area where the resist is not formed.

[0301] With this configuration, even if other information is printed on the resist layer, the visibility of the identification information can be improved, and convenience can be improved.

[0302] The predetermined area may be an area where no pattern wiring is formed.

[0303] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0304] <Main control board and sub control board / Summary> As explained above, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (for example, the main control board 600 shown in FIG. 11) and a second board (for example, the sub-control board 650 shown in FIG. 12), wherein the first board is a board having a fracture surface of a first shape (for example, a fracture surface having a burr 632 generated at the time of fracture as shown in FIG. 11(b)), and the second board is a board having a fracture surface of a second shape (for example, the first fracture surface 650a shown in FIG. 12), and the first shaped fracture surface and the second shaped fracture surface are different shapes.

[0305] According to the gaming machine of this embodiment, it is easy to distinguish between the first and second boards, which improves workability when installing the boards, and can prevent mistakes in installing the boards, etc. In this way, it is possible to provide a gaming machine in which installation mistakes, etc. are reduced.

[0306] In the manufacturing process of gaming machines, the finished circuit board products are covered with various circuit board cases and then installed, fixed, and attached inside the gaming machine. However, since many circuit board products have similar external shapes, installation errors can occur during the manufacturing and assembly of the gaming machine, or, even if they do not result in an installation error, workers can be confused about which circuit board to install, resulting in wasted work time. However, the gaming machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the manufacturing and assembly process of the gaming machine.

[0307] Furthermore, the first substrate may be a substrate having a first resist (e.g., resist layer 604 shown in FIG. 11), the second substrate may be a substrate having a second resist (e.g., resist layer 654 shown in FIG. 12), the fracture surface of the second shape may be a fracture surface having a second convex portion (e.g., convex portion 658a shown in FIG. 12), the fracture surface of the first shape may be a fracture surface having a first convex portion (e.g., convex portion 632a shown in FIG. 11(b)) that is larger than the second convex portion, and the shortest distance from the fracture surface of the first shape to the first resist (e.g., shortest distance x1 shown in FIG. 11(b)) may be longer (farther) than the shortest distance from the fracture surface of the second shape to the second resist (e.g., shortest distance x5 shown in FIG. 12).

[0308] With this configuration, a clearance (work space) can be secured from the recess of the first shape to the resist layer, making it easier to cut the fractured portion formed in the recess of the first shape and improving workability. In addition, even if the cutting work is performed by placing a finger around the periphery of the recess of the first shape or by using a tool, the finger or tool can be prevented from coming into contact with the resist layer or the pattern wiring, thereby preventing damage to the main control board, etc. In this way, a gaming machine can be provided in which defects due to damage to parts are suppressed.

[0309] Furthermore, the first substrate may be a substrate that allows one manufacturer of the gaming machine to be identified by cutting a break portion (for example, break portion 616 shown in Figure 11(a)), and the second substrate may be a substrate that does not have the break portion, and the first shaped break surface may be a break surface formed by cutting the break portion.

[0310] If a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company would increase manufacturing costs, but with this configuration, one or more company names can be printed on one circuit board product, and when each affiliated company manufactures and assembles the gaming machine, they can choose to keep only their own company name or delete unnecessary company names, thereby reducing manufacturing costs and providing gaming machines that do not have any problems during assembly or inspection.

[0311] Furthermore, the first substrate may be a substrate having a fracture surface of a third shape (for example, a fracture surface where burrs are generated during molding), the fracture surface of the third shape being a fracture surface formed during molding of the first substrate, the fracture surface of the first shape being a fracture surface rougher than the fracture surface of the third shape, and the fracture surface of the first shape being a fracture surface located more inward in the first substrate than the fracture surface of the third shape.

[0312] This configuration ensures a clearance (work space) from the recess of the first shape to the resist layer, making it easier to cut the fractured portion formed in the recess of the first shape and improving workability. Furthermore, since the rough fracture surface is located inside the substrate, safety can be improved. In this way, a gaming machine can be provided that suppresses defects caused by component breakage and improves worker safety.

[0313] The fracture surface of the second shape may be a fracture surface that constitutes part of one or more sides of the second substrate.

[0314] With this configuration, the shape of the second substrate can be simplified, and the degree of freedom in circuit design can be improved.

[0315] Furthermore, the first substrate may be a substrate having a first resist (e.g., resist layer 604 shown in FIG. 11), the first substrate may be a substrate having identification information (e.g., identification information 608 shown in FIG. 11) displayed in a predetermined area, the identification information being identification information including information that can identify one manufacturer of the gaming machine, and the predetermined area may be an area where the first resist is not formed.

[0316] With this configuration, even if other information is printed on the resist layer, the visibility of the identification information can be improved, and convenience can be improved.

[0317] The predetermined area may be an area where no pattern wiring is formed.

[0318] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0319] Furthermore, a gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (for example, the main control board 600 shown in FIG. 11), and the first board is a board having a cross-sectional portion of a predetermined shape (for example, the break portion 616 shown in FIG. 11(a)), and the first board is a board having a cross-sectional portion of a specific shape (for example, a molding burr, a concave portion, a convex portion, a cross-section of the long side of the main control board 600, a cross-section of the short side), and the first board is a board having a first resist (for example, the resist layer 604 shown in FIG. 11), and the first board is a board having a shortest distance from the cross-sectional portion of the predetermined shape to the first resist. is a first distance (for example, the shortest distance x1 shown in FIG. 11(b)), the first substrate is a substrate where the shortest distance from the cross-sectional portion of the specific shape to the first resist is a second distance (for example, the shortest distance z1 shown in FIG. 11(b)), the first substrate is a substrate where one manufacturer of the gaming machine can be identified by cutting a break portion, the cross-sectional portion of the predetermined shape is a cross-sectional portion formed by cutting the break portion, the cross-sectional portion of the predetermined shape and the cross-sectional portion of the specific shape are different shapes, and the first distance is longer than the second distance.

[0320] According to the gaming machine of this embodiment, when the fractured portion is cut, it is possible to reduce the distortion caused in the board due to the stress applied to the board, and to prevent damage to the board and the components mounted on the board, etc. In this way, it is possible to provide a gaming machine in which defects caused by component damage are suppressed.

[0321] In the manufacturing process of gaming machines, the finished circuit board products are covered with various circuit board cases and then installed, fixed, and attached inside the gaming machine. However, since many circuit board products have similar external shapes, installation errors can occur during the manufacturing and assembly of the gaming machine, or, even if they do not result in an installation error, workers can be confused about which circuit board to install, resulting in wasted work time. However, the gaming machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the manufacturing and assembly process of the gaming machine.

[0322] Furthermore, the first substrate may be a substrate having a first side (e.g., a long side), the first substrate having a cross-sectional portion of the predetermined shape along the first side, and the first side may be a side parallel to a direction in which stress acts on the first substrate.

[0323] With this configuration, it is possible to reduce distortion in the substrate due to stress applied to the substrate when cutting the breaking portion, thereby preventing damage to the substrate and components mounted on the substrate.

[0324] <Main Control Board According to Modification 1> Next, a main control board 670 (first board) according to Modification 1 will be described with reference to Fig. 15. Figs. 15(a) and (b) are plan views of main control board 670 according to Modification 1.

[0325] The main control board 670 according to the first variant example is configured to include a substrate 672 consisting of a rectangular plate-like body, pattern wiring (not shown) and a resist layer 674 (first resist layer) formed on one side of the substrate 672, multiple types of components 676 mounted on one side of the substrate 672, identification information 678 printed in a predetermined area on one side of the substrate 672 (an area where the pattern wiring and resist layer 674 are not formed), and an identification board 680 having identification information 692 different from the identification information 678.

[0326] 11 shows an example in which board accommodating recess 612 (recess with a first shape) is formed on the right side surface (the short side on the right side when viewed from the front) of main control board 600, but in main control board 670 according to the modified example, board accommodating recess 682 (recess with a first shape) having the same shape as board accommodating recess 612 (recess with a first shape) of main control board 600 is formed on the lower side surface (the long side on the lower side when viewed from the front) of main control board 670. In addition, adapter accommodating recess 684 having the same shape as adapter accommodating recess 614 of main control board 600 is formed on the upper side surface (the long side on the upper side when viewed from the front) of main control board 600.

[0327] The main control board can be applied even if it does not have the adapter accommodating recess 684. Furthermore, the "first board" according to the present invention may not be the main control board, but may be a peripheral board (board for performance) or a relay board.

[0328] According to this example, since board accommodating recess 682 (recess of a first shape) is formed on the long side of main control board 670 (first board), when breaking portion 696 is cut, it is possible to reduce distortion that occurs in base material 672 of main control board 670 (first board) due to stress applied from identification board 680 to base material 672 of main control board 670 (first board), and to prevent damage to base material 672 of main control board 670 (first board) and components mounted on base material 672 of main control board 670 (first board).

[0329] In this modification, the direction in which stress is applied to main control board 670 is the longitudinal direction, and board accommodating recess 682 is provided along the longitudinal direction and arranged in a direction parallel to the direction in which stress is applied. On the other hand, when the fractured portion is cut, a force acts in a direction different from the direction in which stress is applied, so that distortion of base material 672 can be suppressed when the fractured portion is cut.

[0330] Furthermore, if an attempt is made to forcibly remove the main control board 670 (first board) from the main board storage case (for example, the board storage body 642 shown in FIG. 13), the main control board 670 is more likely to be damaged than a main control board having a board storage recess formed on its short side (for example, the main control board 600 shown in FIG. 11(a)), which can leave traces of fraudulent activity and improve security.

[0331] In this example, the identification information 678 is placed near the substrate accommodating recess 682, but the "predetermined area" according to the present invention is not limited to this example and may be placed in an area spaced a predetermined distance from the substrate accommodating recess 682 (for example, the area indicated by symbol A in Figure 15(a) with the resist layer 674 sandwiched between it and the substrate accommodating recess 682).

[0332] According to this example, the distance from the identification information 692 on the identification board 680 is increased, so that the two types of identification information (the identification information 678 and the identification information 692) can be easily distinguished, and work errors and the like can be reduced.

[0333] <Main control board / components according to Modification 1> Next, a description will be given of components 676 mounted on main control board 670 according to the first modification.

[0334] Components 676 implemented on the main control board 670 according to the first modification include passive components 676a (676a1, 676a2) such as resistors, capacitors, and coils, and an IC 676c.

[0335] In the example shown in FIGS. 15(a) and 15(b), a plurality of passive components 676a (676a1, 676a2), an IC 676c, etc. are disposed near the board accommodating recess 682 (first shape recess) of the main control board 670.

[0336] The longitudinal direction of one passive component 676a1 (first passive component) among the multiple passive components 676a is the same as the longitudinal direction of the substrate accommodating recess 682, and the longitudinal direction of one passive component 676a2 (second passive component) among the multiple passive components 676a is a direction different from the longitudinal direction of the substrate accommodating recess 682 and is a direction perpendicular to the longitudinal direction of the substrate accommodating recess 682.

[0337] According to this example, the longitudinal direction of one passive component 676a1 (first passive component) among the multiple passive components 676a is the same as the longitudinal direction of the substrate accommodating recess 682 (recess of first shape), so the effect that the stress applied in the longitudinal direction of the recess of first shape when cutting the fracture portion has on the first passive component mounted on the first substrate can be reduced, and damage to the first passive component can be prevented.

[0338] 15(a) and 15(b), a plurality of passive components 676a (676a1, 676a2), an IC 676c, and the like are also disposed near the adapter accommodating recess 684 of the main control board 670.

[0339] The longitudinal direction of one passive component 676a2 (second passive component) of the plurality of passive components 676a is a direction different from the longitudinal direction of the adapter accommodating recess 684 and is a direction perpendicular to the longitudinal direction of the adapter accommodating recess 684.

[0340] Here, in Figure 15(a), when we focus on the positional relationship between the board accommodating recess 682 of the main control board 670 and the passive component 676a1, and the positional relationship between the adapter accommodating recess 684 and the passive component 676a2, the shortest distance y3 from the board accommodating recess 682 to the passive component 676a1 is configured to be longer than the shortest distance y4 from the adapter accommodating recess 684 to the passive component 676a2 (y3 > y4).

[0341] According to the present example, the shortest distance y3 from the substrate accommodating recess 682 (recess having a first shape) to the passive component 676a1 (first passive component) is longer than the shortest distance y4 from the adapter accommodating recess 684 (recess having a second shape) to the passive component 676a2 (second passive component) (y3>y4). Therefore, a clearance (work space) from the substrate accommodating recess 682 (recess having a first shape) to the passive component 676a1 (first passive component) can be ensured, the fracture portion formed in the substrate accommodating recess 682 (recess having a first shape) can be easily cut, workability can be improved, and even when a cutting operation is performed by hooking a finger around the periphery of the substrate accommodating recess 682 (recess having a first shape) or by using a tool, it is possible to prevent the finger or the tool from coming into contact with the passive component 676a1 (first passive component), thereby preventing damage to the passive component 676a1 (first passive component).

[0342] Also, the shortest distance y4 from the adapter accommodation recess 684 (the second-shaped recess) to the passive component 676a2 (the second passive component) was considered. However, even when there is no adapter accommodation recess and the shortest distance y4' (see Fig. 15(b)) from the passive component 676a2 (the second passive component) on the main control board 670 to the nearest long side is used, it may be set as "y3 > y4'", that is, when "the distance from the breaking part to the first passive component > the distance from the side without the breaking part to the second passive component", the first passive component may be arranged in the same direction as the longitudinal direction of the board accommodation recess. Even when "y3 < y4 (y4')", by arranging the first passive component in the same direction as the longitudinal direction of the board accommodation recess, damage to the components due to the stress during the cutting of the breaking part can be prevented.

[0343] Also, in Fig. 15(b), focusing on the positional relationship between the board accommodation recess 682 of the main control board 670 and the passive component 676a2, and the positional relationship between the adapter accommodation recess 684 and the passive component 676a2, the shortest distance y5 from the board accommodation recess 682 to the passive component 676a2 is configured to be longer than the shortest distance y4 from the adapter accommodation recess 684 to the passive component 676a2 (y5 > y4).

[0344] Also, in Figs. 15(a) and (b), the passive components arranged along the short side of the board such as the passive components 674a4 and 676a5 may be used as the second passive components. The shortest distance y7 from the end of the short side to the passive components 674a4 and 676a5 may also be set as "y3 > y7", and these relationships are the same as those of the passive component 676a2. Also, when the shortest distance γ from the board accommodation recess 682 to the passive components 674a4 and 676a5 is considered, "y3 < γ", and these relationships are also the same as those of the passive component 676a2.

[0345] According to the present example, the shortest distance y5 from the substrate accommodating recess 682 (recess having a first shape) to the passive component 676a2 (second passive component) is longer than the shortest distance y4 from the adapter accommodating recess 684 (recess having a second shape) to the passive component 676a2 (second passive component) (y5>y4). Therefore, a clearance (work space) from the substrate accommodating recess 682 (recess having a first shape) to the passive component 676a2 (second passive component) can be ensured, the fracture portion formed in the substrate accommodating recess 682 (recess having a first shape) can be easily cut, workability can be improved, and even when a cutting operation is performed by hooking a finger around the periphery of the substrate accommodating recess 682 (recess having a first shape) or by using a tool, it is possible to prevent the finger or tool from touching the passive component 676a2 (second passive component). This makes it possible to prevent damage to the passive component 676a2 (second passive component).

[0346] Furthermore, the shortest distance from the adapter accommodating recess 684 (recess of the second shape) to the passive component 676a2 (second passive component) is defined as y4, but even if there is no adapter accommodating recess and y4' is defined as the shortest distance from the long side of the main control board 670 that is closest to the passive component 676a2 (second passive component), it may be "y5>y4'". In other words, by ensuring a distance greater than y4 (y4') and arranging the passive component in a direction perpendicular to the longitudinal direction of the board accommodating recess, it is possible to reduce the effect of stress when the fracture portion is cut and prevent damage to the component.

[0347] Furthermore, when attention is paid to the positional relationship between the board accommodating recess 682 of the main control board 670 and the passive component 676a1 in Figure 15(a) and the positional relationship between the board accommodating recess 682 and the passive component 676a2 in Figure 15(b), the shortest distance y5 from the board accommodating recess 682 to the passive component 676a2 shown in Figure 15(b) is configured to be longer than the shortest distance y3 from the board accommodating recess 682 to the passive component 676a1 shown in Figure 15(a) (y5>y3).

[0348] According to this example, the longitudinal direction of the passive component 676a2 (second passive component) is different from that of the substrate accommodating recess 682 (recess of first shape), and the passive component 676a2 (second passive component) is susceptible to the stress applied in the longitudinal direction of the substrate accommodating recess 682 (recess of first shape) when cutting the breaking portion 696. However, by arranging the passive component 676a2 (second passive component) at a position farther from the substrate accommodating recess 682 (recess of first shape) than the passive component 676a1 (first passive component), damage to the passive component 676a2 (second passive component) can be prevented.

[0349] In addition, other components such as passive component 676a1 (first passive component), an IC, or a resistor array may be arranged within the shortest distance y5 from substrate accommodating recess 682 to passive component 676a2 (second passive component) so that the stress generated when the fracture portion is cut is less likely to affect the second passive component, and in this case, it is preferable that the "other components" are larger than the second passive component.

[0350] Furthermore, when passive component 676a3 in FIG. 15(a) and passive component 676a1 in FIG. 15(b) are placed on the side of substrate accommodating recess 682 (the side of the edge that does not have burrs 632 at the time of fracture), they may be placed closer to substrate accommodating recess 682 than passive components placed on the side of the edge that has burrs 632 at the time of fracture (passive components 676a1 and 676a2 in FIG. 15(a)). Since they are placed in a position that is less susceptible to the stress at the time of fracture, there is no need to consider clearance, and the degree of freedom in substrate design can be increased.

[0351] In addition, such a board accommodating recess may be provided for multiple boards in a single gaming machine. In this case, when passive component A (passive component 616a1) is arranged on one board (for example, FIG. 11(b)) at a distance m1 (distance x3) from the board accommodating recess, and passive component B (passive component 676a2) is arranged on another board (FIG. 15(b)) at a distance m2 (y5) longer than the distance m1 from the board accommodating recess, passive component A may be arranged so that its longitudinal direction coincides with the longitudinal direction of the board accommodating recess, and passive component B may be arranged so that its longitudinal direction is perpendicular to the longitudinal direction of the board accommodating recess because a distance m2 longer than the distance m1 is secured. This ensures flexibility in board design by not uniformly limiting the arrangement direction of passive components when designing the board. Furthermore, if the other board has fewer components mounted on it than the other board and sufficient area for the board mounting surface can be secured, the passive components may be positioned away from the board accommodating recess, and even if the board has a board accommodating recess, if the number of components mounted on the board is small, the board can be designed without considering the orientation of the passive components, and by not uniformly limiting the orientation of the passive components when designing the board, flexibility in board design can be secured. Furthermore, by varying the distance from the board accommodating recess to the passive components and the orientation, depending on the board, it is possible to easily identify which board it is.

[0352] <Main control board for Modification 1 / Summary> As explained above, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (for example, the main control board 670 shown in FIG. 15), the first board is a board having a recess of a first shape (for example, the board accommodating recess 682 shown in FIG. 15), the first board is a board in which one manufacturer of the gaming machine can be identified by cutting a breaking portion (for example, the breaking portion 696 shown in FIG. 15(a)), the recess of the first shape is the portion where the breaking portion is formed, and the recess of the first shape is formed along the long side of the first board.

[0353] According to the gaming machine of this embodiment, a recess of a first shape is formed on the long side of the substrate (first substrate), so that when the breaking portion is cut, it is possible to reduce distortion caused in the substrate by stress applied to the substrate, and to prevent damage to the substrate and components mounted on the substrate, etc. In this way, it is possible to provide a gaming machine in which defects caused by component damage are suppressed.

[0354] Furthermore, when an attempt is made to forcibly remove the board from the main board storage case, the main control board is more susceptible to damage than a main control board having a first-shaped recess formed on the long side, which can leave traces of fraudulent activity, thereby improving security.

[0355] In the manufacturing process of gaming machines, the finished circuit board products are covered with various circuit board cases and then installed, fixed, and attached inside the gaming machine. However, since many circuit board products have similar external shapes, installation errors can occur during the manufacturing and assembly of the gaming machine, or, even if they do not result in an installation error, workers can be confused about which circuit board to install, resulting in wasted work time. However, the gaming machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the manufacturing and assembly process of the gaming machine.

[0356] Furthermore, the first substrate may be a substrate having a plurality of components (for example, passive components 606 such as resistors, capacitors, and coils shown in FIG. 11, or passive components 676 such as resistors, capacitors, and coils shown in FIG. 15(a)), one of the plurality of components may be a first component (for example, passive component 606a1 shown in FIG. 11(b) or passive component 676a1 shown in FIG. 15(a)) arranged near the recess of the first shape, and the longitudinal direction of the recess of the first shape and the longitudinal direction of the first component may be along the long side of the first substrate.

[0357] With this configuration, the effect of stress applied in the longitudinal direction of the recess of the first shape when cutting the breaking portion on the first passive component mounted on the first substrate can be reduced, and damage to the first passive component can be prevented. In this way, a gaming machine can be provided in which defects due to component damage are suppressed.

[0358] The first substrate is a substrate having a side different from the long side, and the first substrate is a substrate having a plurality of components (for example, passive components 606 such as resistors, capacitors, and coils shown in FIG. 11 and passive components 676 such as resistors, capacitors, and coils shown in FIG. 15(a)), and one of the plurality of components is a first component (for example, passive component 606a1 shown in FIG. 11(b) and passive component 676a1 shown in FIG. 15(a)) disposed near the recess of the first shape, and one of the plurality of components is a first component (for example, passive component 606a1 shown in FIG. 11(b) and passive component 676a1 shown in FIG. 15(a)). The component is a second component (e.g., passive component 606a2 shown in FIG. 11(b) or passive component 676a2 shown in FIG. 15(a)) arranged near the certain side, and the shortest distance from the recess of the first shape to the first component (e.g., shortest distance x3 shown in FIG. 11(b) or shortest distance y3 shown in FIG. 15(a)) may be longer than the shortest distance from the certain side to the second component (e.g., shortest distance x4 shown in FIG. 11(b) or shortest distance y4 shown in FIG. 15(a)) (x3>x4, y3>y4).

[0359] With this configuration, a clearance (work space) can be secured from the recess of the first shape to the first passive component, making it easier to cut the fracture portion formed in the recess of the first shape and improving workability. In addition, even when cutting work is performed by placing fingers around the periphery of the recess of the first shape or by using a tool, it is possible to prevent fingers or tools from coming into contact with the first passive component, thereby preventing damage to the first passive component, etc. In this way, a gaming machine can be provided in which defects due to component damage are suppressed.

[0360] Furthermore, the longitudinal direction of the first-shaped recess and the longitudinal direction of the second component may be different directions, and the shortest distance from the first-shaped recess to the second component (e.g., the shortest distance x3' shown in FIG. 11(b) or the shortest distances β and γ shown in FIG. 15(a)) may be longer than the shortest distance from the first-shaped recess to the first component (e.g., the shortest distance x3 shown in FIG. 11(b) or the shortest distance y3 shown in FIG. 15(a)) (x3' > x3, β > y3, γ > y3). Note that the "shortest distance from the first-shaped recess to the second component" may be the distance of a line parallel to the short side of the substrate on an imaginary extension line, or the distance of a diagonal line from the first-shaped recess to the second component.

[0361] With this configuration, the longitudinal direction of the second passive component is different from the direction of the recess of the first shape, and the second passive component is susceptible to the stress applied in the longitudinal direction of the recess of the first shape when the breaking portion is cut, but by arranging the second passive component farther from the recess of the first shape than the first passive component, it is possible to prevent damage to the second passive component. In this way, it is possible to provide a gaming machine in which defects due to component damage are suppressed.

[0362] The housing may also include a container (e.g., substrate container 642 shown in FIG. 14(b)), which is capable of storing the first substrate, and when the first substrate is stored in the housing, a component (e.g., IC 606c shown in FIG. 14(b)) arranged on the first substrate may be visible through a recess of the first shape (e.g., substrate storage recess 612 shown in FIG. 14(b)).

[0363] With this configuration, the board can be easily seen, making it easier to detect unauthorized components when they are installed, and the components mounted on the board can be checked while they are housed in the housing, improving maintenance and workability.

[0364] Furthermore, the first substrate may be a substrate having a resist layer (e.g., resist layer 604 shown in Figure 11), and the first substrate may be a substrate having identification information (e.g., identification information 608 shown in Figure 11) displayed in a predetermined area, the identification information being identification information including information that can identify one manufacturer of the gaming machine, and the predetermined area may be an area where the resist layer is not formed.

[0365] With this configuration, even if other information is printed on the resist layer, the visibility of the identification information can be improved, and convenience can be improved.

[0366] The predetermined area may be an area where no pattern wiring is formed.

[0367] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0368] <Main Control Board According to Modification 2> Next, a main control board 690 (first board) according to Modification 2 will be described with reference to Fig. 16(a). Fig. 16(a) is a plan view of main control board 690 according to Modification 2.

[0369] In the main control board 600 described using Figure 11, an example is shown in which the manufacturer of the gaming machine can be identified by separating the identification board 610, leaving only the identification information 618 (name of manufacturer of slot machine 100: BBB Company, identification number of main control board: XXX-YYY) on the main control board 600.

[0370] However, the "first board" according to the present invention is not limited to this, and for example, as in the main control board 690 according to this modified example 2, the identification board 692 may be configured so that the manufacturer of the gaming machine can be identified by, for example, striking out the identification information 694 (name of the slot machine manufacturer: BBB Company, identification number of the main control board: XXX-YYY) on the main control board 690 by laser engraving or the like, without separating the identification board 692.

[0371] <Main Control Board According to Modification 3> Next, a main control board 696 (first board) according to Modification 3 will be described with reference to Fig. 16(b). Fig. 16(b) is a plan view of main control board 696 according to Modification 3.

[0372] In the main control board 600 described with reference to FIG. 11, an example was shown in which identification information 618 (name of manufacturer of slot machine 100: BBB Company, identification number of main control board: XXX-YYY) is printed on the main control board 600.

[0373] However, the "first board" according to the present invention is not limited to this, and for example, like the main control board 696 according to this modification 3, it may be configured to have a plurality of identification boards 698 that can be detached from the main control board 696, with first identification information (slot machine manufacturer name: AAA company, main control board identification number: XXX-YYY) printed on one of the identification boards 698 and second identification information (slot machine manufacturer name: BBB company, main control board identification number: XXX-YYY) printed on the other identification board 698, and either one of them can be detached.

[0374] <Pattern Arrangement> Next, the arrangement of symbols on the reels 110 to 112 will be described with reference to Figure 26. Figure 26 is a diagram showing the arrangement of symbols on each reel (left reel 110, center reel 111, right reel 112) in a flat layout.

[0375] On each of the reels 110 to 112, a predetermined number of symbols (20 symbols numbered 0 to 19 in this embodiment) of various types (9 symbols in this embodiment) shown on the right side of the figure are arranged. The numbers 0 to 19 shown on the left side of the figure are numbers indicating the arrangement positions of the symbols on each of the reels 110 to 112. For example, in this embodiment, a "watermelon symbol" is arranged on the symbol number 0 on the left reel 110, a "bell symbol" is arranged on the symbol number 1 on the center reel 111, and a "replay symbol" is arranged on the symbol number 0 on the right reel 112.

[0376] <Measures to prevent circuit board fire spread> Hereinafter, measures against the spread of fire on the circuit board of the slot machine according to this embodiment will be described with reference to FIGS.

[0377] <Measures to prevent fire spread on circuit boards / circuit boards> Fig. 17(a) is a plan view of the substrate 700 according to this example as seen from the power supply layer 710 side, and Fig. 17(b) is a partial cross-sectional view of the substrate 700 taken along line XX in Fig. 17(a). For ease of explanation, Fig. 17(b) exaggerates the thicknesses of the conductor layer, insulating layer, and base material in the substrate 700.

[0378] The slot machine according to this example includes a substrate 700 (a certain substrate) shown in Fig. 17(a). As shown in Figs. 17(a) and 17(b), the substrate 700 includes a base material (core) 702, a GND layer (second conductor layer) 706 laminated on the base material 702, a power supply layer (first conductor layer) 710 laminated on the GND layer 706 via an insulating layer 708, a solder resist 713 applied on the power supply layer 710, silk 715 printed on the solder resist 713, and components 712 (such as an LED driver IC 714, a motor driver IC 716, passive components 718, a connector 720, and an LED 721; hereinafter, these are collectively referred to as "components") mounted on the power supply layer 710.

[0379] 17(b) shows an example of a double-sided mounting board in which conductor layers and insulating layers are mounted on both sides of the base material (core) 702, but the present invention is not limited to this and may also be a single-sided mounting board in which conductor layers and insulating layers are mounted on only one side of the base material (core) 702. Furthermore, for convenience of explanation, only the structure of one side of the board 700 will be explained below, and illustrations of solder resist 713, silk 715, etc. will be omitted in the drawings.

[0380] In other words, the substrate 700 (a certain substrate) is a substrate in which a power supply layer (first conductor layer) 710 is formed on one side with an insulating layer 708 sandwiched therebetween, and a GND layer (second conductor layer) 706 is formed on the base material 702 side with the insulating layer 708 sandwiched therebetween.

[0381] The "certain substrate" according to the present invention may be any substrate having at least a plurality of conductor layers, an insulating layer, and a substrate, and may be, for example, a substrate in which the positions of the power supply layer 710 and the GND layer 706 are swapped, i.e., a substrate in which the GND layer (second conductor layer) 706 is configured on one side (upper side) with the insulating layer 708 sandwiched therebetween, and the power supply layer (first conductor layer) 710 is configured on the substrate side (lower side) with the insulating layer 708 sandwiched therebetween, or a substrate having three or more conductor layers, or a substrate having other types of layers in addition to the conductor layer, insulating layer, and substrate. Furthermore, the "certain substrate" according to the present invention may be a double-sided mounted substrate having a conductor layer and an insulating layer sandwiched between the substrate 702.

[0382] Furthermore, the uses of the "certain board" according to the present invention are not particularly limited, and for example, the "certain board" according to the present invention may be the main control board 600 described using FIG. 11, the sub-control board 650 described using FIG. 12, a power supply board that controls the power supply, a dispensing control board that controls dispensing, etc.

[0383] <Board fire prevention measures / components> Next, the component 712 mounted on the substrate 700 will be described.

[0384] As shown in FIG. 17(a), a plurality of components 712 are mounted (placed) on a power supply layer 710 of the substrate 700.

[0385] In this example, components 712 are mounted only on the power supply layer 710, and the GND layer 706 is a GND plane layer (a GND layer on which no components are mounted), but the "certain substrate" according to the present invention may be any substrate on which multiple components are arranged on at least one surface, and for example, components may be mounted only on the GND layer 706, and the power supply layer 710 may be a power supply plane layer (a power supply layer on which no components are mounted), or components may be mounted on both the power supply layer 710 and the GND layer 706. In addition, in the case of a substrate having three or more conductor layers, it is sufficient that multiple components are arranged on at least one layer.

[0386] The "components" according to the present invention are not particularly limited, but in this example, the power supply layer 710 is mounted with active components such as light-emitting devices (not shown) such as LEDs and diodes, an LED driver IC 714 (described later using FIG. 18(a)) that drives the LEDs, and a motor driver IC 716 (described later using FIG. 18(b)) that drives a motor (not shown), as well as passive components 718 such as resistors, capacitors, and coils, and mechanical components such as a connector 720.

[0387] The "active component" according to the present invention is not limited to a light-emitting device or a driver IC, but may be, for example, a diode, a transistor, a light-receiving device such as a photodiode, or various sensors such as a magnetic sensor.

[0388] <Board fire prevention measures / components / LED drivers> FIG. 18(a) is a terminal layout diagram of the LED driver IC 714.

[0389] The LED driver IC714 is configured to have address input terminals A0 to A5 arranged at terminals Nos. 1 to 6, a ground terminal GND arranged at terminals Nos. 7, 20, and 33, constant current output terminals XOUT0 to XOUT23 arranged at terminals Nos. 8 to 19 and 21 to 32, an external resistor connection terminal REXT arranged at terminal No. 34, a reset signal input terminal RESET arranged at terminal No. 35, a serial clock input terminal SCLK arranged at terminal No. 36, a serial data input terminal SDA arranged at terminal No. 37, and a power supply terminal VCC arranged at terminal No. 38.

[0390] The power supply terminal VCC (terminal number 38) of the LED driver IC 714 is soldered to the power supply wiring pattern 711 (described later using Figure 20, etc.) of the power supply layer 710 of the substrate 700, and is electrically connected to the power supply wiring pattern 711 of the power supply layer 710.

[0391] The ground terminals GND (terminal numbers 7, 20, 33) are soldered to the GND wiring pattern 706a (described later using Figure 20, etc.) of the GND layer 706 through vias formed in the insulating layer 708, and are electrically connected to the GND wiring pattern 706a of the GND layer 706.

[0392] The constant current output terminals XOUT0 to XOUT23 (terminal numbers 8 to 19, 21 to 32) are all output terminals, and in this example, are electrically connected to LEDs (not shown) and function as output terminals that drive the LEDs.

[0393] <Board fire prevention measures / components / motor drivers> FIG. 18(b) is a terminal layout diagram of the motor driver IC 716.

[0394] The motor driver IC716 is configured to have a power supply terminal VMA arranged at terminals 2 and 3, a bridge A output 1 terminal AOUT1 arranged at terminals 4 and 5, a bridge A ground output terminal ISENA arranged at terminals 6 and 7, a bridge A output 2 terminal AOUT2 arranged at terminals 8 and 9, a bridge B output 2 terminal BOUT2 arranged at terminals 10 and 11, a bridge B ground output terminal ISENB arranged at terminals 12 and 13, a bridge B output 1 terminal BOUT1 arranged at terminals 14 and 15, a power supply terminal VMB arranged at terminals 16 and 17, a ground terminal GND arranged at terminal 20, a regulator output terminal V3P3OUT arranged at terminal 21, various control signal terminals arranged at terminals 22 to 35, and a reset signal input terminal RESET arranged at terminal 36.

[0395] The power terminals VMA (terminal numbers 2 and 3) and VMB (terminal numbers 16 and 17) of the motor driver IC 716 are soldered to the power wiring pattern 711 of the power layer 710 of the substrate 700 and are electrically connected to the power wiring pattern 711 of the power layer 710.

[0396] The ground terminal GND (terminal number 20) is soldered to the GND wiring pattern 706a of the GND layer 706 through a via formed in the insulating layer 708, and is electrically connected to the GND wiring pattern 706a of the GND layer 706.

[0397] The bridge A output 1 terminal AOUT1 (terminal numbers 4 and 5), the bridge A ground output terminal ISENA (terminal numbers 6 and 7), the bridge A output 2 terminal AOUT2 (terminal numbers 8 and 9), the bridge B output 2 terminal BOUT2 (terminal numbers 10 and 11), the bridge B ground output terminal ISENB (terminal numbers 12 and 13), and the bridge B output 1 terminal BOUT1 (terminal numbers 14 and 15) are all output terminals, which in this example are electrically connected to a motor (not shown) and function as output terminals that drive the motor.

[0398] <Board fire prevention measures / power layer> Next, the power supply layer 710 of the substrate 700 will be described.

[0399] Figure 19(a) is a pattern diagram showing an example of a power wiring pattern of the power supply layer 710 of the substrate 700, and Figure 20(a) is a partially enlarged view of the power supply layer 710, showing an enlarged portion indicated by the symbol A in Figure 19(a).

[0400] As shown enlarged in Figure 20(a), the power supply layer (first conductor layer) 710 of the substrate 700 is formed with a plurality of power supply wiring patterns (first wiring patterns) 711 (711a to 711g) and pads, lands, vias, etc. electrically connected to these power supply wiring patterns 711 (711a to 711g).

[0401] The power wiring pattern 711a is configured to have a first power line 711a1, and two power lines, a second power line 711a2 and a third power line 711a3, which branch off from one end of the first power line 711a1 as a base end.

[0402] A power supply wiring pattern 711b is formed adjacent to and below the first power supply line 711a1 of the power supply wiring pattern 711a, and a plurality of pads 722 are formed on the first power supply line 711a1 of the power supply wiring pattern 711a and the power supply wiring pattern 711b, on which components (resistors, capacitors, diodes, etc.) arranged across these power supply wiring patterns are mounted.

[0403] The power supply wiring pattern 711b is connected to a power supply of a predetermined voltage (in this example, DC 24v). The first power supply line 711a1 of the power supply wiring pattern 711a is electrically connected to the power supply wiring pattern 711b via a component mounted on the pad 722, and therefore functions as a power supply line of the same voltage (in this example, DC 24v) as the power supply wiring pattern 711b.

[0404] A power supply wiring pattern 711c is formed closely between the second power supply line 711a2 and the third power supply line 711a3 of the power supply wiring pattern 711a, and the second power supply line 711a2 and the third power supply line 711a3 and the power supply wiring pattern 711c are formed with a plurality of pads 724 on which components (resistors, capacitors, diodes, etc.) arranged across these power supply wiring patterns are mounted.

[0405] The power supply wiring pattern 711c is electrically connected to the second power supply line 711a2 and the third power supply line 711a3 of the power supply wiring pattern 711a via components mounted on the pad 724, and therefore functions as a power supply line of the same voltage (in this example, DC24v) as the power supply wiring patterns 711a and 711b.

[0406] In Figure 20(a), the power supply wiring pattern 711d located on the left side, the power supply wiring pattern 711e located in the center, and the power supply wiring patterns 711f and 711g located on the right side are connected directly or indirectly (via components) to a power supply of a predetermined voltage (in this example, DC5v) and function as DC5v power supply lines.

[0407] It should be noted that the "first wiring pattern" according to the present invention is not limited to a power supply wiring pattern, and for example, if the "first conductor layer" according to the present invention is defined as a GND layer, the "first wiring pattern" according to the present invention becomes a GND wiring pattern. It goes without saying that the voltage value of the power supply supplied to the "power supply wiring pattern" according to the present invention is not limited to this example.

[0408] <Board fire prevention / GND layer> Next, the GND layer 706 of the substrate 700 will be described.

[0409] Figure 19(b) is a pattern diagram showing the GND wiring pattern 706a of the GND layer 706 of the substrate 700, and Figure 20(b) is a partially enlarged view of the GND layer 706, showing an enlarged portion indicated by the symbol B in Figure 19(b).

[0410] As shown in Figures 17(b) and 20(b), the GND layer (second conductor layer) 706 of the substrate 700 is composed of a GND wiring pattern 706a consisting of a so-called ground solid (solid wiring pattern) and a pattern cutout (solid cutout) 706b where this GND wiring pattern 706a is not formed (cutout).

[0411] The GND wiring pattern 706a of the substrate 700 according to this example is configured as a solid ground (solid wiring pattern), and therefore the noise resistance (current capacity) of the substrate 700 can be ensured.

[0412] It should be noted that the "second wiring pattern" according to the present invention is not limited to a GND wiring pattern, and for example, if the "second conductor layer" according to the present invention is defined as a power supply layer, the "second wiring pattern" according to the present invention becomes a power supply wiring pattern.

[0413] <Board fire prevention measures / GND layer / non-overlapping area and overlapping area> Next, the non-overlapping area NOE and the overlapping area OE of the substrate 700 will be described.

[0414] FIG. 20(c) is a pattern diagram showing the power supply layer 710 shown in FIG. 20(a) superimposed on the GND layer 706 shown in FIG. 20(b).

[0415] Non-overlapping of substrate 700 region As shown in Figure 17(b), the NOE is an area in the thickness direction of the substrate 700 where the power supply wiring pattern 711 and the GND wiring pattern 706a do not overlap, and in this example, it is composed of a first non-overlapping area NOE1 where the power supply wiring pattern 711 is formed but the GND wiring pattern 706a is not formed (composed of pattern hole 706b), and a second non-overlapping area NOE2 where neither the power supply wiring pattern 711 nor the GND wiring pattern 706a is formed.

[0416] The "non-overlapping region" according to the present invention may be a region in which the first wiring pattern and the second wiring pattern do not overlap in the thickness direction of the substrate, and may be, for example, a region in which the power supply wiring pattern 711 is formed in the thickness direction of the substrate but the GND wiring pattern 706a is not formed, or a region without the second non-overlapping region NOE2 in which both the power supply wiring pattern 711 and the GND wiring pattern 706a are not formed.

[0417] On the other hand, the overlapping area OE is an area where the power supply wiring pattern 711 and the GND wiring pattern 706a overlap in the thickness direction of the substrate 700, as shown in FIG. 17(b).

[0418] The "overlapping region" may be any region in which the first wiring pattern and the second wiring pattern overlap in the thickness direction of the substrate, and may be, for example, a region in which a power wiring pattern and a signal wiring pattern are formed in the thickness direction of the substrate, or a region in which a GND wiring pattern and a signal wiring pattern are formed in the thickness direction of the substrate.

[0419] <Board fire prevention measures / positional relationship between non-overlapping areas and components> Next, the positional relationship between the non-overlapping area NOE of the substrate 700 and the components mounted on the power supply layer 710 (LED driver IC 714, motor driver 716) will be described with reference to FIG.

[0420] Fig. 21(a) is a plan view showing the positional relationship between the pattern cutout 706b of the GND layer 706 and the LED driver IC 714 and motor driver 716 mounted on the power supply layer 710. In Fig. 21(a), the LED driver IC 714 and the motor driver 716 are mounted upside down relative to the orientation shown in Figs. 18(a) and (b).

[0421] As explained using Figure 18(a), the power supply terminal VCC (terminal number 38) of the LED driver 714 is soldered to the power supply wiring pattern 711 of the power supply layer 710 of the substrate 700 and is electrically connected to the power supply wiring pattern 711 of the power supply layer 710.

[0422] FIG. 21(b) is a cross-sectional view taken along line YY of the LED driver 714 shown enlarged in FIG. 21(a).

[0423] As shown in Figure 21(b), the GND layer 706 below the power supply wiring pattern 711 to which the power supply terminal VCC (terminal number 38) of the LED driver 714 is connected does not have a GND wiring pattern 706a formed thereon, but is composed of a pattern gap 706b.

[0424] That is, the area where the power supply terminal VCC (terminal number 38) of the LED driver 714 is implemented is the non-overlapping area NOE where the power supply wiring pattern 711 and the GND wiring pattern 706a do not overlap in the thickness direction of the substrate 700 (in this example, the area where the power supply wiring pattern 711 of the power supply layer 710 is formed and the GND wiring pattern 706a of the GND layer 706 is not formed).

[0425] According to this example, by providing a non-overlapping area NOE in which the power supply wiring pattern 711 (first wiring pattern) and the GND wiring pattern 706a (second wiring pattern) arranged on either side of the insulating layer do not overlap in the thickness direction of the substrate, it is possible to prevent a situation in which, for example, a fire from a terminal of a component or the like causes part of the insulating layer of the substrate to become a carbonized conductive path, causing a short circuit between the upper and lower wiring patterns that were insulated by the insulating layer.By preventing fire from the gaming machine, it is possible to provide a gaming machine that is highly safe.

[0426] On the other hand, the GND layer 706 below the conductor layer to which the other terminals of the LED driver 714 are connected is a solid wiring pattern.

[0427] According to this example, it is possible to form the GND wiring pattern as a solid wiring pattern, which not only simplifies the design but also improves the noise resistance of the board.

[0428] In addition, by configuring the power supply layer 710 above the GND wiring pattern 706a to which the ground terminal GND (terminal numbers 7, 20, 33) of the LED driver 714 is connected without a pattern on which the power supply wiring pattern 711 is not formed, the area on which the ground terminal GND (terminal numbers 7, 20, 33) of the LED driver 714 is mounted may be a non-overlapping area NOE (an area on which the GND wiring pattern 706a of the GND layer 706 is formed and the power supply wiring pattern 711 of the power supply layer 710 is not formed) where the power supply wiring pattern 711 and the GND wiring pattern 706a do not overlap in the thickness direction of the substrate 700.

[0429] As explained using Figure 18(b), the power terminal VMA (terminal numbers 2 and 3) and the power terminal VMB (terminal numbers 16 and 17) of the motor driver IC 716 are soldered to the power wiring pattern 711 of the power layer 710 of the substrate 700 and are electrically connected to the power wiring pattern 711 of the power layer 710.

[0430] FIG. 21(c) is a cross-sectional view taken along line ZZ of the motor driver 716 shown enlarged in FIG. 21(a).

[0431] As shown in Figure 21(c), the GND layer 706 below the power wiring pattern 710 to which the power terminal VMA (terminal number 2) of the motor driver 716 is connected does not have a GND wiring pattern 706a formed thereon, and is instead composed of a pattern gap 706b.

[0432] That is, the area where the power supply terminal VMA (terminal number 2) of the motor driver 716 is implemented is the non-overlapping area NOE where the power supply wiring pattern 711 and the GND wiring pattern 706a do not overlap in the thickness direction of the substrate 700 (in this example, the area where the power supply wiring pattern 711 of the power supply layer 710 is formed and the GND wiring pattern 706a of the GND layer 706 is not formed).

[0433] According to this example, by providing a non-overlapping area NOE in which the power supply wiring pattern 711 (first wiring pattern) and the GND wiring pattern 706a (second wiring pattern) arranged on either side of the insulating layer do not overlap in the thickness direction of the substrate, it is possible to prevent a situation in which, for example, a fire from a terminal of a component or the like causes part of the insulating layer of the substrate to become a carbonized conductive path, causing a short circuit between the upper and lower wiring patterns that were insulated by the insulating layer.By preventing fire from the gaming machine, it is possible to provide a gaming machine that is highly safe.

[0434] Although not shown in the figure, the GND layer 706 below the power wiring pattern 711 to which the power terminal VMA (terminal number 3) and power terminal VMB (terminal numbers 16 and 17) of the motor driver 716 are connected also does not have a GND wiring pattern 706a formed therein, and is instead composed of a pattern gap 706b.

[0435] Moreover, the power supply layer 710 above the GND wiring pattern 706a to which the ground terminal GND (terminal number 20) is connected is configured as a pattern blank in which the power supply wiring pattern 711 is not formed.

[0436] As described with reference to FIG. 18(b), the bridge A output 1 terminal AOUT1 (terminal numbers 4 and 5), the bridge A ground output terminal ISENA (terminal numbers 6 and 7), the bridge A output 2 terminal AOUT2 (terminal numbers 8 and 9), the bridge B output 2 terminal BOUT2 (terminal numbers 10 and 11), the bridge B ground output terminal ISENB (terminal numbers 12 and 13), and the bridge B output 1 terminal BOUT1 (terminal numbers 14 and 15) of the motor driver IC 716 are all output terminals that are electrically connected to a motor (not shown) and drive the motor.

[0437] In this example, the GND layer 706 below the signal wiring patterns to which these output terminals are connected does not have a GND wiring pattern 706a formed thereon, but is instead composed of pattern holes 706b.

[0438] That is, the "non-overlapping region" according to the present invention may be a region in which the first wiring pattern and the second wiring pattern do not overlap in the thickness direction of the substrate, and may be, for example, a region in which a signal wiring pattern (first wiring pattern) is formed in the thickness direction of the substrate but a GND wiring pattern (second wiring pattern) is not formed, or a region in which a GND wiring pattern (first wiring pattern) is formed in the thickness direction of the substrate but a signal wiring pattern (second wiring pattern) is not formed.

[0439] Furthermore, it may be an area in which a signal wiring pattern (first wiring pattern) is formed in the thickness direction of the substrate, but a power supply wiring pattern (second wiring pattern) is not formed, or an area in which a power supply wiring pattern (first wiring pattern) is formed in the thickness direction of the substrate, but a signal wiring pattern (second wiring pattern) is not formed.

[0440] On the other hand, the GND layer 706 below the conductor layer to which terminals other than the power terminal, GND terminal, and output terminal of the motor driver 716 (for example, input terminals such as the reset signal input terminal RESET (terminal number 36) and various control signal terminals (terminal numbers 22 to 35)) are connected is a solid wiring pattern.

[0441] According to this example, it is possible to form the GND wiring pattern as a solid wiring pattern, which not only simplifies the design but also improves the noise resistance of the board.

[0442] Furthermore, in this example, as shown in FIG. 21(a), multiple (six in this example) LED drivers 714 and multiple (two in this example) motor drivers 716 are arranged on the substrate 700, each spaced apart at a predetermined interval, and therefore the non-overlapping areas NOE formed on each LED driver 714 and motor driver 716 are also formed spaced apart on the substrate 700.

[0443] Although forming the power supply wiring pattern and the GND wiring pattern as a solid wiring pattern can improve the noise resistance of the board, a certain degree of reduction in noise resistance is unavoidable because the solid wiring pattern is removed in the non-overlapping area. However, since the noise resistance is significantly reduced when the solid wiring pattern is removed in succession, forming the non-overlapping area at a distance can prevent a significant reduction in noise resistance caused by forming the power supply wiring pattern and the GND wiring pattern as a solid wiring pattern.

[0444] Note that the area of ​​pattern opening 706b as the non-overlapping region increases as the number of output terminals and power supply terminals of the drivers increases. In other words, the non-overlapping region near a first driver (first active component) that has many terminals (specific terminals) that may generate heat or cause a fire is larger than the non-overlapping region near a second driver (second active component) that has fewer terminals (specific terminals) that may generate heat or cause a fire than the first driver.

[0445] 19(a) and 21 indicate via holes x1, x2, and x3, and no GND wiring pattern is laid in these portions (note that in the embodiments, vias and through holes are collectively referred to as "via holes"). Via holes x1 and x2 are via holes provided near the output terminals and power supply terminals of LED driver 714 and motor driver 716, and via hole x1 is disposed on an extension of the wiring pattern connected to motor driver 716, while via hole x2 is disposed on an extension of the wiring pattern connected to LED driver 714 and an adjacent pattern. The non-laid portions of the GND wiring pattern corresponding to via holes x1 and x2 are continuously formed with pattern hole 706b formed as a fire prevention measure. In this way, by continuously forming the non-laying portions of the GND wiring pattern corresponding to the via holes x1 and x2 located near the driver and the pattern cutouts as a fire prevention measure, it is possible to provide an effective fire prevention measure even if the carbonized conductive path becomes larger than if the patterns were not formed continuously, and even if a fire does spread to the board, it can be kept localized.

[0446] On the other hand, the via hole x3, which is located away from the LED driver 714 and the motor driver 716, is not continuous with the pattern hole 706b, is not arranged on the extension line of the wiring pattern connected to the LED driver 714 or the motor driver 716, and is not arranged on the extension line of the wiring pattern adjacent to the wiring pattern connected to the LED driver 714 or the motor driver 716.

[0447] <Measures to prevent fire from spreading on circuit boards / Conventional problems and the concept of the present invention> Next, the problems of the prior art and the concept of the present invention will be explained.

[0448] Fig. 22(a) is a conceptual diagram that shows the problem of the circuit board of a conventional gaming machine. In Fig. 22 and Fig. 23, for the sake of simplicity, only the power supply layer, insulating layer, and GND layer of the circuit board are shown.

[0449] Gaming machines, such as slot machines, are equipped with various circuit boards. These boards are equipped with active and passive components, and the active and passive components generate heat in different ways when driven to a large extent.

[0450] Specifically, while passive components themselves become hot, the hottest part of active components is near the output terminal. As shown in Figure 22(a-2), if the area near the terminal of the IC (component) becomes hot, there is a risk of a short circuit (spark), and in this case, the generated sparks may gouge (destroy) the insulating layer of the substrate.

[0451] As shown in Figure 22(a-3), when the insulating layer of the substrate is destroyed, the wiring pattern near the terminal of the IC (component) is carbonized, and part of the insulating layer becomes a carbonized conductive path, which can cause a short circuit between the upper and lower wiring patterns that were insulated by the insulating layer (in this example, the upper power supply layer and the lower GND layer), which can lead to a fire.

[0452] FIG. 22(b) is a diagram showing a schematic diagram of the substrate concept of the present invention.

[0453] The substrate of the present invention is characterized in that it has a non-overlapping area NOE (in this example, an area where the power supply wiring pattern 711 of the power supply layer 710 is formed and the GND wiring pattern 706a of the GND layer 706 is not formed) in which the power supply wiring pattern 711 and the GND wiring pattern 706a do not overlap in the thickness direction of the substrate 700, as shown in Figure 22 (b-1).

[0454] Since the substrate of the present application has such a non-overlapping area NOE, even if the temperature near the terminal of the IC (component) becomes high and sparks are generated, as shown in Figure 22 (b-2), and the generated sparks destroy the insulating layer 708 of the substrate, as shown in the same figure (b-3), since the non-overlapping area NOE is an area where the GND wiring pattern 706a is not formed (an area where pattern cutout 706b is applied), it is possible to prevent a short circuit from occurring between the upper and lower wiring patterns (in this example, the upper power supply layer 710 and the lower GND layer 706) that were insulated by the insulating layer 708, and by preventing the gaming machine from catching fire, a highly safe gaming machine can be provided.

[0455] In this example, the non-overlapping area NOE is an example of an "area where a power wiring pattern on the power supply layer is formed and a GND wiring pattern on the GND layer is not formed." However, it may also be an "area where a GND wiring pattern on the GND layer is formed and a power wiring pattern on the power supply layer is not formed," or an area including an "area where neither a power wiring pattern on the power supply layer nor a GND wiring pattern on the GND layer is formed."

[0456] <Board fire spread prevention / non-overlapping area (Example 1)> FIG. 23(a) is a plan view showing the non-overlapping area NOE and the assumed maximum area CE of the carbonized conductive path according to Example 1, and FIG. 23(b) is a cross-sectional view taken along line AA in FIG. 23(a).

[0457] 23(a) and 23(b), the non-overlapping area NOE of the substrate 700 needs to be an area large enough to include at least the assumed maximum area CE of the carbonized conductive path assumed in the substrate 700. In other words, as shown in Fig. 23(b), it is necessary to prevent the power supply wiring pattern 711 of the power supply layer 710, the assumed maximum area CE of the carbonized conductive path, and the GDN wiring pattern 706a of the GND layer 706 from overlapping in the thickness direction of the substrate 700.

[0458] Figure 23(c) is a plan view showing an example in which the non-overlapping area NOE of the substrate 700 does not include the entire assumed maximum area CE of the carbonized conductive path, and Figures 23(d) and (d') are cross-sectional views along line BB in Figure 23(c).

[0459] As shown in Figures 23(c) and (d), if the non-overlapping area NOE of the substrate 700 is an area large enough not to include the entire maximum assumed area CE of the carbonized conductive path, as shown in Figure 23(d'), the generated sparks will destroy the insulating layer 708 of the substrate 700, forming a carbonized conductive path of the maximum assumed area CE, which may result in a short circuit between the power supply layer 710 and the GND layer 706, which were insulated by the insulating layer 708, and may induce a fire.

[0460] The assumed maximum area CE of the carbonized conductive path will differ depending on the structure and characteristics of the component mounted on the board. For example, even if the component is composed of a main body and a terminal, if the junction between the main body and the terminal is the part that is most likely to generate heat and reach high temperatures, then the assumed maximum area CE of the carbonized conductive path will be a range centered on this junction. However, if the internal connection between the circuit inside the main body and the terminal is the part that is most likely to generate heat and reach high temperatures, then the assumed maximum area CE of the carbonized conductive path will be a range centered on this internal connection.

[0461] In other words, the "non-overlapping region" according to the present invention is preferably a region located near the part of each component that is most likely to generate heat and reach a high temperature. Furthermore, if the terminals of the components are thick, the expected maximum area of ​​the carbonized conductive path will be correspondingly larger, so the range of the non-overlapping region must also be large.

[0462] <Board fire prevention / non-overlapping area (other examples)> FIG. 24(a) is a plan view showing the non-overlapping area NOE2 according to the second embodiment.

[0463] In this embodiment, a non-overlapping area NOE2 (in this embodiment, a rectangular area having a height of H2 and a width of W2) is formed so as to include the entire component 712 (in this embodiment, a DIP-type IC) mounted on the power layer 710. In the drawing, the power terminal is arranged on one side of the IC in the short-side direction, but in the example shown in Fig. 24(a), it is preferable to arrange the power terminals on both sides of the short-side direction and distributed above and below.

[0464] The non-overlapping area NOE2 of the substrate 700 may be an area large enough to include at least the maximum area CE of the carbonized conductive path expected on the substrate 700. However, since there is a risk of carbonized conductive paths being formed in the vicinity of the components 712 and the power wiring pattern 711, if the average width of the power wiring pattern 711 of the power supply layer 710 is w1, the maximum width is w2, and the maximum horizontal length of the power wiring pattern 711 is w3, it is preferable that the width W2 of the non-overlapping area NOE2 is longer than any of these, and that the relationship be "average width w1 of the power wiring pattern 711 < maximum width w2 of the power wiring pattern 711 < maximum horizontal length w3 of the power wiring pattern 711 < width W2 of the non-overlapping area NOE2."

[0465] For the same reason, if the maximum vertical length of the power supply wiring pattern 711 is h1, the height H2 of the non-overlapping area NOE2 is longer than that, and it is preferable that the relationship be "maximum vertical length h1 of the power supply wiring pattern 711 < height H2 of the non-overlapping area NOE2".

[0466] According to this example, the non-overlapping area NOE2 is an area large enough to include at least the maximum assumed area CE of the carbonized conductive path, and the power supply wiring pattern 711 of the power supply layer 710, the maximum assumed area CE of the carbonized conductive path, and the GDN wiring pattern 706a of the GND layer 706 do not overlap in the thickness direction of the substrate. This makes it possible to prevent a short circuit from occurring between the upper and lower wiring patterns that are insulated by an insulating layer (in this example, the upper power supply layer and the lower GND layer), and by preventing fires from the gaming machine, it is possible to provide a gaming machine that is highly safe.

[0467] Furthermore, since the non-overlapping area NOE2 is an area large enough to include the entire component 712 and the power wiring pattern 711, even if a carbonized conductive path is formed near the component 712 or the power wiring pattern 711, it is possible to prevent a short circuit from occurring between the upper and lower wiring patterns that are insulated by the insulating layer (in this example, the upper power supply layer and the lower GND layer), thereby preventing the gaming machine from catching fire and providing a highly safe gaming machine.

[0468] FIG. 24(b) is a plan view showing the non-overlapping area NOE3 according to the third embodiment.

[0469] In this example, a non-overlapping area NOE3 (in this example, a rectangular area with a height H3 and a width W3) is formed so as to include all terminals on one side in the short direction of a component 712 (in this example, a DIP-type IC) mounted on the power layer 710. Note that in the figure, the power terminals are arranged lower on one side in the short direction of the IC, but in the example shown in Fig. 24(b), it is preferable that the power terminals are arranged on one side in the short direction.

[0470] According to this example, the non-overlapping area NOE3 is an area large enough to include at least the maximum assumed area CE of the carbonized conductive path, and the power supply wiring pattern 711 of the power supply layer 710, the maximum assumed area CE of the carbonized conductive path, and the GDN wiring pattern 706a of the GND layer 706 do not overlap in the thickness direction of the substrate. This makes it possible to prevent a short circuit from occurring between the upper and lower wiring patterns that are insulated by an insulating layer (in this example, the upper power supply layer and the lower GND layer), and by preventing fires from the gaming machine, it is possible to provide a gaming machine that is highly safe.

[0471] Furthermore, since the non-overlapping area NOE3 is an area large enough to include the power supply wiring pattern 711, even if a carbonized conductive path is formed near the power supply wiring pattern 711, it is possible to prevent a short circuit from occurring between the upper and lower wiring patterns that are insulated by an insulating layer (in this example, the upper power supply layer and the lower GND layer), thereby preventing the gaming machine from catching fire and providing a highly safe gaming machine.

[0472] Furthermore, according to this example, the size of the non-overlapping area NOE3 can be made smaller than the non-overlapping area NOE2 in Example 2, and the area of ​​the GND wiring pattern 706a of the GND layer 706 can be increased accordingly, thereby improving the noise resistance (current capacity) of the substrate.

[0473] FIG. 24(c) is a plan view showing the non-overlapping area NOE4 according to the fourth embodiment.

[0474] In this example, a non-overlapping area NOE4 (in this example, a rectangular area with a height H4 and a width W4) is formed so as to include a plurality of terminals on one longitudinal side of a component 712 (in this example, a DIP-type IC) mounted on the power layer 710. Note that in the figure, the power terminals are arranged lower on one side in the short direction of the IC, but in the example shown in Fig. 24(c), it is preferable that the power terminals are arranged on one longitudinal side.

[0475] According to this example, the non-overlapping area NOE4 is an area large enough to include at least the maximum expected area CE of the carbonized conductive path, and the power supply wiring pattern 711 of the power supply layer 710, the maximum expected area CE of the carbonized conductive path, and the GDN wiring pattern 706a of the GND layer 706 do not overlap in the thickness direction of the substrate. This makes it possible to prevent a short circuit from occurring between the upper and lower wiring patterns that are insulated by an insulating layer (in this example, the upper power supply layer and the lower GND layer), and by preventing fires from the gaming machine, it is possible to provide a gaming machine that is highly safe.

[0476] Furthermore, since the non-overlapping region NOE4 is an area large enough to include the power supply wiring pattern 711, even if a carbonized conductive path is formed near the power supply wiring pattern 711, it is possible to prevent a situation where a short circuit occurs between the upper and lower wiring patterns (in this example, the upper power supply layer and the lower GND layer) that are insulated by the insulating layer. By preventing ignition from the game table, a game table with high safety can be provided.

[0477] Also, according to this example, the size of the non-overlapping region NOE4 can be made smaller than the non-overlapping region NOE2 according to Example 2. Accordingly, the area of the GND wiring pattern 706a of the GND layer 706 can be increased, and the noise resistance (current capacity) of the substrate can be enhanced.

[0478] FIG. 25(a) is a plan view showing the non-overlapping region NOE5 according to Example 5, and FIG. 25(b) is a plan view showing an example in which the wiring pattern of the power supply wiring line in FIG. 25(a) is changed.

[0479] The substrate of this example includes a first power supply wiring pattern 711x capable of supplying power of a first voltage (for example, DC24v) to the component 712, and a second power supply wiring pattern 711y capable of supplying power of a second voltage (for example, DC5v) to the component 712.

[0480] In the examples shown in FIGS. 25(a) and 25(b), it is common that a non-overlapping region is formed so as to include the first power supply wiring pattern 711x and the second power supply wiring pattern 711y. However, in the example shown in FIG. 25(b), since the first power supply wiring pattern 711x is arranged closer to the second power supply wiring pattern 711y, the non-overlapping region NOE5' shown in FIG. 25(b) (in this example, a rectangular region with a height H5 and a width W5') has a smaller area than the non-overlapping region NOE5 shown in FIG. 25(a) (in this example, a rectangular region with a height H5 and a width W5).

[0481] In the example shown in Figure 25(b), the first power supply wiring pattern 711x and the second power supply wiring pattern 711y, which supply power from different power sources to the component 712, are arranged close to each other, so the size of the non-overlapping area NOE5' can be made smaller than the non-overlapping area NOE5 shown in the same Figure 25(a).As a result, the area of ​​the GND wiring pattern 706a (solid wiring pattern) of the GND layer 706 can be increased, and the noise resistance (current capacity) of the board can be improved.

[0482] <Summary of measures to prevent circuit board fire spread> As explained above, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1, a pachinko machine, an enclosed gaming machine, or a medalless slot machine) is a gaming machine on which games can be played, and the gaming machine is equipped with a certain substrate (for example, the substrate 700 shown in FIG. 17(a)), and the certain substrate is a substrate that is configured to have at least a plurality of conductor layers, an insulating layer (for example, the insulating layer 708 shown in FIG. 17(b)), and a base material (for example, the base material 702 shown in FIG. 17(b)), and the certain substrate is a substrate on which a plurality of components are arranged on at least one side, and one of the plurality of conductor layers is a first conductor having a first wiring pattern (for example, the power supply wiring patterns 710a to 710g shown in FIG. 20(a)). the certain substrate is a substrate having the first conductor layer on one side thereof with the insulating layer sandwiched therebetween (e.g., the power supply layer 710 shown in FIG. 17(b)), one of the plurality of conductor layers is a second conductor layer (e.g., the GND layer 706 shown in FIG. 17(b)) having a second wiring pattern (e.g., the GND wiring pattern 706a shown in FIG. 20(b)), the certain substrate is a substrate having the first conductor layer on one side thereof with the insulating layer sandwiched therebetween, the certain substrate is a substrate having the second conductor layer on the base material side with the insulating layer sandwiched therebetween, and the certain substrate is a substrate having a non-overlapping region (e.g., the non-overlapping region NOE shown in FIG. 17(b)) in which the first wiring pattern and the second wiring pattern do not overlap in the thickness direction of the certain substrate.

[0483] According to the gaming machine of this embodiment, by providing a non-overlapping region in which the first wiring pattern and the second wiring pattern arranged with the insulating layer sandwiched therebetween do not overlap in the thickness direction of the board, for example, if the board is damaged (breakage during transportation, cracks, or other scratches), the resistance at the damaged area increases, which may promote heat generation and carbonization, resulting in a short circuit. Even if such a situation occurs, the damage can be prevented from spreading by not overlapping the wiring patterns. Furthermore, it is possible to prevent a situation in which a fire from a terminal or the like of a component causes part of the insulating layer of the board to become a carbonized conductive path, causing a short circuit between the upper and lower wiring patterns that were insulated by the insulating layer. By preventing fire from the gaming machine, a highly safe gaming machine can be provided.

[0484] Furthermore, one of the multiple components may be a certain component (for example, the LED driver 714 or the motor driver 716 shown in FIG. 21(a)), and the non-overlapping area may be located in the vicinity of the certain component (for example, one longitudinal side of the LED driver 714 shown in FIG. 21(a), one lateral side of the motor driver 716 shown in FIG. 21(a), an area including the entire component 712 shown in FIG. 24(a), one lateral side of the component 712 shown in FIG. 24(b), or one longitudinal side of the component 712 shown in FIG. 24(c)).

[0485] With this configuration, even if a certain component shorts out, by making the area around the component a non-overlapping area, it is possible to prevent a situation in which a short circuit occurs between the upper and lower wiring patterns that are insulated by the insulating layer.

[0486] Furthermore, the certain component may be a specific active component (for example, an LED driver 714 shown in FIG. 21(a), a motor driver 716, a light-emitting device, a diode, a transistor, a light-receiving device such as a photodiode, or various sensors such as a magnetic sensor).

[0487] With this configuration, active components are more susceptible to short circuits than passive components, and there is a risk that sparks caused by a short circuit could gouge the substrate, causing part of the substrate's insulating layer to become a carbonized conductive path. However, by making the area near the active components a non-overlapping area, it is possible to prevent situations in which a short circuit occurs between the wiring patterns on the upper and lower layers that are insulated by the insulating layer.

[0488] Furthermore, the area on the certain substrate where components other than the specific active component (e.g., passive components such as resistors, components that are unlikely to spark at high temperatures) are arranged may be an overlap area where the first wiring pattern and the second wiring pattern overlap in the thickness direction of the certain substrate.

[0489] With this configuration, it becomes possible to form the power supply wiring pattern and the GND wiring pattern as solid wiring patterns in the overlapping area, thereby improving the noise resistance of the board.

[0490] Furthermore, the non-overlapping region (for example, the non-overlapping region NOE shown in FIG. 17(b)) may be a region in which either the first wiring pattern or the second wiring pattern (for example, the power supply wiring pattern 711 shown in FIG. 17(b)) is formed, and in which the other of the first wiring pattern or the second wiring pattern (for example, the GND wiring pattern 706a shown in FIG. 17(b)) is not formed.

[0491] With this configuration, the first wiring pattern and the second wiring pattern can be physically separated, thereby preventing a situation in which a short circuit occurs between the upper and lower wiring patterns that are insulated by an insulating layer.

[0492] Furthermore, the first wiring pattern may be either a power supply wiring pattern or a GND wiring pattern (for example, the power supply wiring pattern 711 shown in FIG. 17(b)), and the second wiring pattern may be the other of the power supply wiring pattern and the GND wiring pattern (for example, the GND wiring pattern 706a shown in FIG. 17(b)).

[0493] With this configuration, the power supply wiring pattern and the GND wiring pattern can be physically separated, thereby preventing a situation in which a short circuit occurs between the power supply wiring pattern and the GND wiring pattern that are insulated by the insulating layer.

[0494] Furthermore, the first wiring pattern may be either a signal wiring pattern (for example, a signal line to which the output terminal of the motor driver IC 716 shown in Figure 18(b) or Figure 21(c) is connected) or a GND wiring pattern (for example, the GND wiring pattern 706a shown in Figure 17(b)), and the second wiring pattern may be the other of the signal wiring pattern and the GND wiring pattern.

[0495] With this configuration, the signal wiring pattern and the GND wiring pattern can be physically separated, thereby preventing a situation in which a short circuit occurs between the signal wiring pattern and the GND wiring pattern that are insulated by the insulating layer.

[0496] Furthermore, the first wiring pattern may be either a signal wiring pattern (for example, a signal line to which the output terminal of the motor driver IC 716 shown in Figure 18(b) or Figure 21(c) is connected) or a power supply wiring pattern (for example, the power supply wiring pattern 711 shown in Figure 17(b)), and the second wiring pattern may be the other of the signal wiring pattern and the power supply wiring pattern.

[0497] With this configuration, the signal wiring pattern and the power supply wiring pattern can be physically separated, and it is possible to prevent a situation in which a short circuit occurs between the signal wiring pattern and the power supply wiring pattern that are insulated by the insulating layer.

[0498] Furthermore, the certain substrate may be a substrate in which at least one of the first wiring pattern and the second wiring pattern (for example, the GND wiring pattern 706a shown in Figure 20(b) or Figures 21(a) to (c)) is configured as a solid wiring pattern, the certain substrate may be a substrate in which a plurality of the specific active components (for example, the LED driver 714 and the motor driver 716 shown in Figure 18 or Figure 21(a)) are arranged (for example, in Figure 21, a plurality of LED drivers 714 (ICs of the same type) are arranged spaced apart, a plurality of motor drivers 716 (ICs of the same type) are arranged spaced apart, or the LED driver 714 and the motor driver 716 (ICs of different types) are arranged spaced apart), the certain substrate may be a substrate in which the non-overlapping regions are formed corresponding to the respective specific active components, and the certain substrate may be a substrate in which the respective non-overlapping regions are formed spaced apart.

[0499] Although forming the power supply wiring pattern and the GND wiring pattern as a solid wiring pattern can improve the noise resistance of the board, a certain degree of reduction in noise resistance is unavoidable because the solid wiring pattern is removed in the non-overlapping area. However, since the noise resistance is significantly reduced when the solid wiring pattern is removed in succession, forming the non-overlapping area at a distance can prevent a significant reduction in noise resistance caused by forming the power supply wiring pattern and the GND wiring pattern as a solid wiring pattern.

[0500] <Pattern Arrangement> Next, the arrangement of symbols on the reels 110 to 112 will be described with reference to Figure 26. Figure 26 is a diagram showing the arrangement of symbols on each reel (left reel 110, center reel 111, right reel 112) in a flat layout.

[0501] On each of the reels 110 to 112, a predetermined number of symbols (20 symbols numbered 0 to 19 in this embodiment) of various types (9 symbols in this embodiment) shown on the right side of the figure are arranged. The numbers 0 to 19 shown on the left side of the figure are numbers indicating the arrangement positions of the symbols on each of the reels 110 to 112. For example, in this embodiment, a "watermelon symbol" is arranged on the symbol number 0 on the left reel 110, a "bell symbol" is arranged on the symbol number 1 on the center reel 111, and a "replay symbol" is arranged on the symbol number 0 on the right reel 112.

[0502] <Types of winning roles> Next, the types of winning combinations of the slot machine 100 will be described with reference to Figure 27. Figure 27 is a diagram showing the types of winning combinations, the names of the condition devices, the symbol combinations corresponding to each winning combination, the payout amounts, and remarks.

[0503] The winning combinations of the slot machine 100 include special combinations (special combination 1, special combination 2) and general combinations (replay combinations 1 to 3, small combinations 1 to 5). The types of winning combinations are not limited to these combinations and can be arbitrarily adopted, and some of the winning combinations are not shown in FIG. 27.

[0504] <Types of winning roles / special roles> Among the winning combinations in this embodiment, special combination 1 and special combination 2 are combinations that transition to a special game state in which a predetermined benefit is awarded to the player. Also, the replay combination is a combination that allows replay without inserting new medals (a combination that awards replay). These winning combinations are sometimes called "operation combinations."

[0505] In addition, "winning" in this embodiment also includes cases where a pattern combination of an operating role that does not involve a medal payout (does not involve the payment of medals) is displayed on the winning line, and includes, for example, winning special role 1, special role 2, and re-play role.

[0506] Special Role 1 and Special Role 2 are winning roles that transition the game state to the Special Role 1-2 internal winning state (RT3) upon internal winning, and then transition the game state to the Special Role 1-2 game state (RT4) upon winning. In addition, if more than the specified number of medals (for example, 200 medals) are paid out in the Special Role 1-2 game state (RT4), the game state transitions to the low replay probability state (RT1). Each game state (RT1 to RT4) will be described later.

[0507] The symbol combination corresponding to special role 1 (BB) is "Seven 1 symbol - Seven 1 symbol - Seven 1 symbol" or "Seven 2 symbol - Seven 2 symbol - Seven 2 symbol", and the symbol combination corresponding to special role 2 (RB) is "BAR symbol - BAR symbol - BAR symbol".

[0508] When special role 1 or special role 2 is internally won, the special role internal win flag corresponding to this internally won role is set to ON (stored in a predetermined area of ​​RAM 308 of the main control unit 300). This flag remains ON until the internally won role is won, making it easier to win that internally won role in subsequent games. In other words, in a game in which special role 1 or special role 2 is internally won, even if the special role is not won, the special role will be internally won in subsequent games, making it easier to win the symbol combination corresponding to the special role.

[0509] <Type of winning combination / replay combination> Replay roles 1 to 3 are winning roles (operating roles) that allow a player to play the next game without inserting medals (game media) when they are won, and no medals are paid out. The corresponding symbol combinations are as shown in FIG. 8. Note that a replay role may be any role that allows a player to play the next game without inserting medals. Therefore, for example, when a replay role is won, medals may be automatically inserted in the next game (the number of inserted medals is reset in the medal insertion number storage area), or medals inserted in a game in which a replay role is won may be carried over and used in the next game.

[0510] <Type of winning role / small role> Small winning combinations 1 to 5 are winning combinations in which a predetermined number of medals are paid out (there is a payout number).

[0511] Minor win 1 (watermelon) is a winning combination in which the pattern combination "watermelon pattern - watermelon pattern - watermelon pattern" is displayed stopped on the winning line, and five medals are paid out.

[0512] Minor win 2 (Cherry) is a winning combination in which the symbol combination "Cherry symbol-ANY-ANY" is stopped and displayed on the winning line, and two medals are paid out. Note that the symbol combination "Cherry symbol-ANY-ANY" only requires that the symbol on the left reel 110 is a "Cherry symbol," and the symbols on the center reel 111 and right reel 112 can be any symbol.

[0513] Hereinafter, these small prizes 1 (watermelon) and 2 (cherry) may be collectively referred to as "rare prizes", but rare prizes are not limited to these winning prizes, and may be either one of the winning prizes, or may include other winning prizes.

[0514] In addition, if you win a rare role in the AT state described below, a lottery to add the number of games or the number of sets will be executed (making it easier to win the lottery). On the other hand, even if you win a rare role in the ED state, a lottery to add the number of games or the number of sets will not be executed.

[0515] The small prize 3 (push order bell) is composed of six types of winning prizes, small prize 3a to small prize 3f. In this example, by lottery, with a predetermined probability (in this example, about 1 / 6. Common to all settings), one of the winning prizes, small prize 3a to small prize 3f, is internally won, and if the operation order (push order) of the stop operation by the stop buttons 137 to 139 matches the corresponding winning prize, the prize is won, and 12 medals are paid out.

[0516] The minor winning combination 4 (common bell) is a winning combination in which, regardless of the order (pressing order) or timing of the stop operation by the stop buttons 137 to 139, the symbol combination of "bell symbol - bell symbol - bell symbol" stops and is displayed on the winning line, and 12 medals are paid out.

[0517] The minor winning combination 5 (single medal winning combination) is a winning combination in which, regardless of the order (pressing order) or timing of the stop operation by the stop buttons 137 to 139, the symbol combination of "replay symbol - replay symbol - blank 1 symbol" stops and is displayed on the winning line, and 1 medal is paid out.

[0518] <Types of RT-based game states> Next, the types and transitions of RT-based game states in the slot machine 100 will be described.

[0519] <Re-game low probability state (RT1)> The re-game low probability state (RT1) is the default RT-based game state (hereinafter also referred to as the "normal game state") that is first set immediately after the power of the slot machine 100 is turned on, etc., and is a game state that is relatively disadvantageous for the player compared to other game states.

[0520] In this example, in this re-game low probability state (RT1), when winning the re-game winning combination 2 (upgraded replay 1) or the re-game winning combination 3 (upgraded replay 2), it transitions to the re-game high probability state (RT2) described later. Also, in this re-game low probability state (RT1), when internally winning the special winning combination 1 or the special winning combination 2, it transitions to the special winning combination 1·2 internal winning state (RT3) described later.

[0521] <Re-game high probability state (RT2)> The re-game high probability state is a game state in which the internal winning probability of the re-game is higher than that in the re-game low probability state (RT1).

[0522] In this example, in this re-game high probability state (RT2), when internally winning the special winning combination 1 or the special winning combination 2, it transitions to the special winning combination 1·2 internal winning state (RT3) described later.

[0523] <Special role 1·2 internal winning state (RT3)> The special role 1·2 internal winning state (RT3) is a state in which the internal winning flag corresponding to special role 1 or special role 2 is set to on, and by the player performing a stop operation at a predetermined timing, the symbol combination corresponding to the special role corresponding to this flag can be displayed. It is a gaming state.

[0524] In this example, in this special role 1·2 internal winning state (RT3), when winning a prize in special role 1 or special role 2, it transitions to the special gaming state (RT4) described later.

[0525] <Special gaming state (RT4)> The special gaming state (RT4) is the most advantageous gaming state for the player among all gaming states. In this example, in the special gaming state (RT4), when a specified number of coins (for example, 200 coins) are paid out, it transitions to the low probability of re - gaming state (RT1).

[0526] Note that in this example, the end condition of the special gaming state (RT4) is not particularly limited, and for example, it may be when winning an internal prize for a specified role, when there are winnings a specified number of times (for example, 8 times), or when a specified number of games (for example, 6 times) are played.

[0527] <Transition of AT - type gaming states> Next, the AT - type gaming states will be described.

[0528] The AT - type gaming states are roughly classified into a low - navigation state and a high - navigation state. The low - navigation state is a state where the probability of executing the operation navigation is low, and is also referred to as the normal mode, non - advantageous section, or normal section. The high - navigation state is a state where the probability of executing the operation navigation is higher than that of the low - navigation state, and is also referred to as the AT mode or advantageous section.

[0529] Here, operation navigation refers to a presentation that notifies the stop operation mode of the stop buttons 137 to 139 (for example, the correct operation sequence or the timing of the stop operation) in order to acquire medals or maintain an advantageous gaming state, and includes, for example, a presentation that notifies the correct operation sequence of a push order role (for example, minor role 3 (push order bell LCR)) (for example, a presentation that displays the letters "left → center → right").

[0530] When a player performs a stop operation according to the operation content of the operation navigation, the result is advantageous to the player, so the high navigation state is a gaming state that is more advantageous to the player than the low navigation state. Here, advantageous specifically means that the ratio of the total number of gaming media paid out by the gaming machine to the total number of gaming media used by the player as the number of bets on the gaming machine when playing for a predetermined period of time, that is, the so-called payout rate (ball payout rate), is advantageous.

[0531] In this example, the low navigation state is defined as a state in which the probability of operation navigation being executed is low, and the high navigation state is defined as a state in which the probability of operation navigation being executed is higher than in the low navigation state. However, the low navigation state may also be defined as a state in which operation navigation is not executed, and the high navigation state as a state in which operation navigation is executed.

[0532] Each game state of the AT system is subdivided and managed, and these are called presentation states. In detail, the presentation state of the low navigation state is the normal game state, and the presentation state of the high navigation state includes the normal state, the confirmation notification state, the judgement state, the pullback state, the AT1 state, the AT2 state, and the ED (ending) state. In principle, the AT1 state, the AT2 state, and the ED state are states in which the number of balls released increases.

[0533] In this embodiment, when a certain condition is met in the normal game state in the low navigation state (for example, when a winning combination other than a miss is won), the game transitions to the normal state in the high navigation state. After that, for example, the game transitions in the order of the confirmation notification state → AT1 state → judgement state, and from this judgement state, there is a route to transition to the normal game state or AT2 state via the pull-back state, or a route to transition directly from the judgement state to the AT2 state.

[0534] The AT state (AT1 state, AT2 state) is a state in which AT play is possible a predetermined number of times (for example, 30 games per set), and is a state that is more advantageous for the player than the normal play state in a low navigation state or the normal state in a high navigation state.

[0535] In this AT game, at the start of the AT game, a set continuation lottery (for example, a lottery with a 1 / 4 probability of winning) is held to determine whether or not to continue the AT game, and if the set continuation lottery is won, a predetermined number of AT games (in this example, one set of 30 games) are awarded, and the AT state is extended. Also, if the conditions for transitioning to the normal game state are met in the AT state (in this example, when all games in the AT state have been played), the game will transition to the normal game state from the next game.

[0536] Also, when the number of remaining games in the high navigation state falls below a predetermined number (for example, 20 games), the state transitions to an ED state, and in this ED state, an ED (ending) effect is executed, indicating the end of the high navigation state.

[0537] The condition for transitioning to the ED state is not limited to the number of remaining games in the high navigation state being less than a predetermined number of games (for example, 20 games), but may be, for example, that the predetermined number of games is more or less than 20 games, or that "number of coins won + expected difference in number of coins won > 2000".

[0538] <Main processing in the main control section> First, the main control unit main processing executed by the CPU 304 of the main control unit 300 will be described with reference to Fig. 28. This figure is a flowchart showing the flow of the main control unit main processing.

[0539] As described above, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 338 that outputs a start signal (reset signal) when power is turned on. When this start signal is input, the CPU 304 of the basic circuit 302 is reset and started by a reset interrupt, and executes the main processing of the main control unit shown in Fig. 28 in accordance with the control program previously stored in the ROM 306.

[0540] When the power is turned on, first, various initial settings are performed in step S101. These initial settings include setting a stack initial value to the stack pointer (SP) of the CPU 304, setting interrupt prohibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, and setting operation permission and initial values ​​for the WDT 314.

[0541] In step S102, a bet number setting / start operation acceptance process is executed. Here, whether or not medals have been inserted is checked, and preparations are made to send an insertion command indicating that medals have been inserted. If a replay role was won in the previous game, a process is performed to insert the same number of medals as the number inserted in the previous game, eliminating the need for the player to insert medals. Also, a check is made to see if the start lever 135 has been operated, and if the start lever 135 has been operated, the process proceeds to step S103.

[0542] In step S103, the number of inserted medals is determined, and a win line determination process is performed to determine the valid win lines.

[0543] In step S104, the random number generated by the random number generating circuit 316 is obtained, and a winning combination internal lottery process is performed. In the winning combination internal lottery process, the winning combination lottery table stored in ROM 306 is read out according to the current game state, and an internal lottery is performed using this and the obtained random number value, and preparations are made to send an internal lottery command indicating the result of this internal lottery to the first sub-control unit 400. If any winning combination (including an operating combination) is internally won as a result of the internal lottery, the flag for that winning combination is turned on.

[0544] In step S105, a reel stop data selection process is performed to select reel stop data based on the internal lottery result of the winning combination internal lottery process. This reel stop data is stored in the ROM 306 of the main control unit 300. In step S105, preparations are made to send a reel stop data command containing information about the selected reel stop data to the first sub-control unit 400.

[0545] In step S106, a presentation state control process for controlling the game state of the AT system is executed based on the start lever operation. In step S107, a presentation process is executed. In this presentation process, various presentations are controlled.

[0546] In step S108, a reel rotation start process is executed, and all the reels 110 to 112 start rotating.

[0547] In step S109, a reel stop control process is performed. In the reel stop control process, the stop buttons 137 to 139 can be accepted, and when one of the stop buttons is pressed, a stop table of reel stop data is referenced to stop the reel corresponding to the pressed stop button, and one of the reels 110 to 112 is stopped according to the number of reel pull-in frames set in the stop table. When all the reels 110 to 112 have stopped, the process proceeds to step S110. In this step S109, for each stop operation, preparations are made to send to the first sub-control unit 400 a stop button acceptance command (more specifically, a stop button acceptance 1 command for the first stop operation, a stop button acceptance 2 command for the second stop operation, and a stop button acceptance 3 command for the third stop operation) relating to the stop button 137 to 139 that was operated to stop, and for each reel stop, preparations are made to send to the first sub-control unit 400 a reel stop command (more specifically, a reel stop 1 command for the first stopped reel, a reel stop 2 command for the second stop operation, and a reel stop 3 command for the third stop operation) relating to the reel stop position.

[0548] In step S110, a winning determination process is performed to determine whether a player has won a prize. In this winning determination process, if a symbol combination corresponding to a winning role is displayed on an activated winning line, it is determined that the player has won that winning role. For example, if "Bell-Bell-Bell" is lined up on an activated winning line, it is determined that the player has won minor role 3 (Bell). In addition, in this step S110, preparations are made to send a winning determination command indicating the result of the winning determination to the first sub-control unit 400.

[0549] In step S111, a medal awarding process is performed. In the medal awarding process, if any winning combination that provides a payout is achieved, medals in the number corresponding to the winning combination are paid out according to the number of winning lines.

[0550] In step S112, a game state control process is performed. In the game state control process, processing related to the transition of each game state of the RT system is performed, and the game state is transitioned when the start condition or end condition is met. In addition, preparations are made to send a game state command including information indicating the current game state of the RT system.

[0551] In step S113, the controller 100 executes a performance state control process for controlling the game state of the AT system described above. In step S114, the controller 100 executes a high-level navigation state termination process for terminating the high-level navigation state.

[0552] This completes one game. After that, the game progresses by returning to step S102 and repeating the above-mentioned process. The various commands prepared in the above steps are transmitted in the command setting and transmission process (step S206 in FIG. 29) of the main control unit timer interrupt process, which will be described later.

[0553] <Main control unit timer interrupt processing> Next, the main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to Fig. 29. The figure is a flowchart showing the flow of the main control unit timer interrupt process.

[0554] The main control unit 300 is equipped with a counter timer 312 that generates a timer interrupt signal at a predetermined period (approximately once every 2 ms in this embodiment), and this timer interrupt signal is used as a trigger to start main control unit timer interrupt processing at the predetermined period.

[0555] In step S201, a timer interrupt start process is performed, which includes processes such as temporarily saving the values ​​of each register of the CPU 304 in a stack area.

[0556] In step S202, WDT314 is restarted periodically (in this embodiment, once every 2 ms, which is the period of the main control unit timer interrupt) to prevent the count value of WDT314 from exceeding the initial setting value (32.8 ms in this embodiment) and causing a WDT interrupt (to prevent processing abnormalities from being detected).

[0557] In step S203, an input port state update process is performed. In this input port state update process, detection signals from the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310, and the presence or absence of the detection signals is monitored and stored in signal state storage areas partitioned for each of the various sensors 318 in the RAM 308.

[0558] In step S204, various game processes are executed, and processes according to the interrupt status are executed. In step S2005, timer update processing is performed. More specifically, various timers are updated in their respective time units.

[0559] In step S206, a command setting transmission process is performed, and various commands that have been prepared for transmission are transmitted to the first sub-control unit 400. The first sub-control unit 400 is able to determine the presentation control in response to changes in game control in the main control unit 300 based on the command type contained in the received output schedule information, and is also able to determine the content of the presentation control based on the command data information contained in the output schedule information.

[0560] In step S207, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 651, which is separate from the slot machine 100, via the information output circuit 334.

[0561] In step S208, device monitoring processing is performed. In this device monitoring processing, first, the signal states of the various sensors 318 stored in the signal state storage area in step S203 are read out to monitor for errors related to medal insertion abnormalities, medal payout abnormalities, etc., and if an error is detected (not shown), error processing is executed. Furthermore, depending on the current game status, settings are made for the medal selector 170 (a medal blocker operated by a solenoid provided in the medal selector 170), various lamps 339, and various 7-segment (SEG) indicators.

[0562] In step S209, it is monitored whether the low voltage signal is on or not, and if the low voltage signal is on (if a power cutoff is detected), the process proceeds to step S211, and if the low voltage signal is off (if a power cutoff is not detected), the process proceeds to step S210.

[0563] In step S210, various processes are performed to end the timer interrupt end process. In this timer interrupt end process, the values ​​of each register temporarily saved in step S2001 are set back to the original registers. Then, the process returns to the main process of the main control unit shown in FIG.

[0564] On the other hand, in step S211, specific variables and stack pointers for restoring the state to the state at the time of power outage when power is restored are saved as recovery data in a predetermined area of ​​RAM 308, power outage processing such as initialization of input / output ports is performed, and then the process returns to the main processing of the main control unit shown in Figure 28.

[0565] <Processing of the first sub-control unit> Next, the processing of the first sub-control unit 400 will be explained using Figure 30. Figure 30(a) is a flowchart of the main processing executed by the CPU 404 of the first sub-control unit 400. Figure 30(b) is a flowchart of the command reception interrupt processing of the first sub-control unit 400. Figure 30(c) is a flowchart of the timer interrupt processing of the first sub-control unit 400.

[0566] First, the main processing of the first sub-control unit 400 will be described using FIG. 30(a).

[0567] When the power is turned on, an initialization process is first executed in step S301. In this initialization process, the input / output ports are initially set up, and a storage area in RAM 408 is initialized. In this process, an area for storing internal win information, which is information showing the result of an internal win, and an area for storing RT update information, which is information showing the game status, are provided in RAM 408.

[0568] In step S302, it is determined whether the timer variable is 10 or greater, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or greater, the process proceeds to step S3003. In step S303, 0 is substituted into the timer variable. In step S304, command processing, which is processing corresponding to each command received from the main control unit 300, is executed.

[0569] In step S305, a performance control process is performed. Here, performance preparation is performed in accordance with the performance reservation information stored in the performance reservation area in RAM 408. This preparation includes, for example, reading performance data from ROM 406 and updating the performance data if it needs to be updated.

[0570] In step S306, sound control processing is performed based on the processing result of step S305. For example, if the performance data read in step S305 includes a command for the sound source IC 418, this command is output to the sound source IC 418. In step S307, lamp control processing is performed based on the processing result of step S305. For example, if the performance data read in step S305 includes a command for the various lamps 420, this command is output to the drive circuit 422.

[0571] In step S308, shutter control processing is performed based on the processing result of step S3005. For example, if the performance data read out in step S305 contains a command for the shutter 163, this command is output to the drive circuit 424. In step S309, information output processing is performed to set up sending a command to the second sub-control unit 500 based on the processing result of step S305. For example, if the performance data read out in step S305 contains a command to be sent to the second sub-control unit 500, settings are made to output this control command, and the process returns to step S302.

[0572] Next, using Figure 30(b), we will explain the command reception interrupt processing of the first sub-control unit 400. This command reception interrupt processing is processing that the first sub-control unit 400 executes when it detects a strobe signal output by the main control unit 300. In step S401 of the command reception interrupt processing, the command output by the main control unit 300 is stored as an unprocessed command in a command memory area provided in RAM 408.

[0573] Next, using Figure 30(c), we will explain the first sub-control unit timer interrupt processing executed by the CPU 404 of the first sub-control unit 400. The first sub-control unit 400 is equipped with a hardware timer that generates a timer interrupt at a predetermined period (once every 2 ms in this embodiment), and this timer interrupt triggers the execution of the timer interrupt processing at a predetermined period.

[0574] In step S501, 1 is added to the value of the timer variable storage area of ​​RAM 408 described in step S302 in the first sub-control unit main processing shown in Figure 30(a) and stored in the original timer variable storage area. Therefore, in step S302, the value of the timer variable is determined to be 10 or greater every 20 ms (2 ms x 10). In step S502, commands are sent to the second sub-control unit 500 set in step S309, and the random number value for presentation is updated, etc.

[0575] <Processing of the second sub-control unit> Next, the processing of the second sub-control unit 500 will be explained using Figure 31. Figure 31(a) is a flowchart of the main processing executed by the CPU 504 of the second sub-control unit 500. Figure 31(b) is a flowchart of the command reception interrupt processing of the second sub-control unit 500. Figure 31(c) is a flowchart of the timer interrupt processing of the second sub-control unit 500. Figure 31(d) is a flowchart of the image control processing of the second sub-control unit 500.

[0576] First, in step S601 of Figure 31(a), various initial settings are performed. When power is turned on, initialization processing is first executed in step S601. This initialization processing includes initial setting of input / output ports, initialization processing of storage areas in RAM 508, initialization processing of storage areas in VRAM 536, etc.

[0577] In step S602, it is determined whether the timer variable is greater than or equal to 10, and this process is repeated until the timer variable becomes greater than or equal to 10. When the timer variable becomes greater than or equal to 10, the process proceeds to step S603. In step S4003, 0 is assigned to the timer variable. In step S604, command processing is performed. In command processing, the CPU 504 of the second sub-control unit 500 determines whether a command has been received from the CPU 404 of the first sub-control unit 400.

[0578] In step S605, effect control processing is performed. Specifically, if a new command is received in step S604, processing corresponding to this command is performed. For example, processing is executed to read effect data for image control related to the background image from ROM 506. In addition, processing is executed to read other effect data from ROM 506, and if the effect data needs to be updated, processing to update the effect data is also executed.

[0579] In step S606, image control processing (described in detail below) is performed based on the processing result of step S605. For example, if the performance data read in step S605 contains an image control command, image control corresponding to this command is performed. For example, image control related to the display image (announcement image, background image) is executed. When this image control processing is completed, the process returns to step S602.

[0580] Next, using Figure 31 (b), we will explain the command reception interrupt processing of the second sub-control unit 500. This command reception interrupt processing is processing that the second sub-control unit 500 executes when it detects a strobe signal output by the first sub-control unit 400.

[0581] In step S701 of the command reception interrupt processing, the command output by the first sub-control unit 400 is stored in a command storage area provided in the RAM 508 as an unprocessed command.

[0582] Next, using Figure 31 (c), we will explain the second sub-control unit timer interrupt processing executed by the CPU 504 of the second sub-control unit 500. The second sub-control unit 500 is equipped with a hardware timer that generates a timer interrupt at a predetermined period (once every 2 ms in this embodiment), and this timer interrupt triggers the execution of the timer interrupt processing at a predetermined period.

[0583] In step S801, 1 is added to the value of the timer variable storage area of ​​RAM 508 described in step S602 in the second sub-control unit main processing shown in Figure 31(a), and the result is stored in the original timer variable storage area. Therefore, in step S602, the timer variable value is determined to be 10 or greater every 20 ms (2 ms x 10). In step S802, processing such as updating the random number value for presentation is performed.

[0584] Next, the image control processing of step S606 in the main processing of the second sub-control unit 500 will be described with reference to Figure 31(d). This figure is a flowchart showing the flow of the image control processing.

[0585] In step S901, an instruction to transfer image data is issued. Here, the CPU 504 first swaps the designation of the drawing areas of display area A and display area B of the VRAM 536. As a result, one frame of image stored in a display area not designated as a drawing area is displayed on the performance image display device 157. Next, the CPU 504 sets ROM coordinates (source address in ROM 506), VRAM coordinates (destination address in VRAM 536), etc. in the attribute register of the VDP 534 based on the position information table, and then sets a command to start transferring image data from ROM 506 to VRAM 536. The VDP 534 transfers the image data from ROM 506 to VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

[0586] In step S902, it is determined whether or not a transfer end interrupt signal has been input from the VDP 534. If a transfer end interrupt signal has been input, the process proceeds to step S903; if not, the process waits for the transfer end interrupt signal to be input.

[0587] In step S903, parameters are set based on the rendering scenario configuration table, attribute data, etc. Here, CPU 504 instructs VDP 534 on information about the image data that constitutes the display image (coordinate axes of VRAM 536, image size, VRAM coordinates (placement coordinates), transparency, etc.) in order to form a display image in display area A or B of VRAM 536 based on the image data transferred to VRAM 536 in step S901. VDP 534 sets parameters in accordance with the attributes based on the command stored in the attribute register.

[0588] In step S904, a drawing instruction is issued. In this drawing instruction, the CPU 504 instructs the VDP 534 to start drawing an image. The VDP 534 starts drawing an image in the frame buffer in accordance with the instruction from the CPU 504.

[0589] In step S905, it is determined whether a generation completion interrupt signal has been input from VDP 534 based on the completion of image drawing. If a generation completion interrupt signal has been input, the process proceeds to step S906; if not, the process waits for the generation completion interrupt signal to be input.

[0590] In step S906, a scene display counter, which is set in a predetermined area of ​​the RAM 508 and counts how many scene images have been generated, is incremented (+1), and the process ends.

[0591] <Internal winning role lottery value> FIG. 32(a) is a diagram showing an example of the lottery values ​​of the internal winning combinations of the slot machine 100.

[0592] The probability of winning an internal win is calculated by dividing the numerical data corresponding to the range of lottery data associated with each internal win by the numerical data of the range of random numbers obtained at the time of the internal lottery (65536 in this embodiment). The lottery data is divided into several numerical ranges in advance, and each numerical range is associated with each internal win or loss.

[0593] In the winning combination internal lottery process, it is determined whether the random number value obtained as a result of executing the internal lottery is a value corresponding to the lottery data corresponding to any of the internal winning combinations, and the internal winning combination is determined. In practice, this lottery data is prepared with settings 1 to 6, each with a different winning probability for at least one internal winning combination, and the staff of the gaming facility can arbitrarily select and set any of the setting values.

[0594] Regarding the setting values, the probability of winning the internal winning role may be the same for each setting value, while the probability of winning the AT (ease of transitioning to the AT) may be different for settings 1 to 6. For example, in setting 1, the probability of drawing the AT when a certain internal winning role is determined may be probability A, while in setting 6, the probability of drawing the AT when a certain internal winning role is determined may be probability B, which is higher than probability A.

[0595] In the example shown in Figure 32(a), the range of lottery data (lottery value) is indicated by letters. Replay 4 to Replay 7 all show (g), which indicates that the lottery value is the same. For example, (g) = 3000 / 65535. 1-piece role 1 to 1-piece role 8 all show (m), which also indicates that the lottery value is the same. Bell CLR1 to Bell RCL3 all show (n), which also indicates that the lottery value is the same.

[0596] The relationship of the lottery values ​​indicated by the letters is (a) + (b) + (c) + (d) < (e) + (f) + (g) + (h) + (i) + (j) + (k) + (l) + (m) + (n). Note that the watermelon and cherry roles are rare roles with small lottery values.

[0597] <Pushing order> FIG. 32(b) is a table showing the display mode and payout number for each operation content of the common bell and push order combination among the internal winning combinations.

[0598] The push order combination refers to an internal winning combination in which the winning combination (the display mode of the reels 110 to 112) differs depending on the contents of the stop operation (in this embodiment, the operation order from the first stop operation to the third stop operation).

[0599] In this embodiment, (1) the stop operation of left, center, and right (the stop operation in which the first stop reel is the left reel 110, the second stop reel is the center reel 111, and the third stop reel is the right reel 112) is an LCR operation, (2) the stop operation of left, right, and center (the stop operation in which the first stop reel is the left reel 110, the second stop reel is the right reel 112, and the third stop reel is the center reel 111) is an LRC operation, (3) the stop operation of center, left, and right (the stop operation in which the first stop reel is the center reel 111, the second stop reel is the left reel 110, and the third stop reel is the right reel 112) is a CLR operation, and (4) the stop operation of center, right, and left (the stop operation in which the first stop reel is the center reel 111, the second stop reel is the right reel 112, and the third stop reel is the center reel 111) is a CLR operation. (4) a stop operation in which the first stop reel is the right reel 112, the second stop reel is the left reel 110, and the third stop reel is the center reel 111) is sometimes referred to as a CRL operation, (5) a stop operation in which the right, left, center (a stop operation in which the first stop reel is the right reel 112, the second stop reel is the center reel 111, and the third stop reel is the center reel 111) is sometimes referred to as an RLC operation, and (6) a stop operation in which the right, center, left (a stop operation in which the first stop reel is the right reel 112, the second stop reel is the center reel 111, and the third stop reel is the left reel 110) is sometimes referred to as an RCL operation.

[0600] For example, if push order bell_CLR1-3 is an internal winner in the internal lottery for winning roles, (1) if an LCR operation or an LRC operation is performed, the winner will lose or win a 1-coin role, and 0 or 1 medal will be paid out; (2) if a CLR operation is performed, the winner will win a bell, and 9 medals will be paid out; (3) if a CRL operation is performed, the winner will win a 1-coin role, and 1 medal will be paid out; and (4) if an RLC operation or an RCL operation is performed, the winner will lose or win a 1-coin role, and 0 or 1 medal will be paid out.

[0601] In other words, when the CLR operation is performed, the push order bells CLR1 to CLR3 will win the bell and the maximum number of medals will be paid out. Hereinafter, when the push order role is internally won, the operation content when the maximum number of medals is paid out may be referred to as the "correct operation." In this embodiment, the correct operation means that the operation sequence from the first stop operation to the third stop operation is correct.

[0602] Similarly, for Push Order Bell_CRL1-3, the correct operation is CRL operation, and if CRL operation is performed, the bell will be won and 9 medals will be paid out. Also, for Push Order Bell_RLC1-3, the correct operation is RLC operation, and if RLC operation is performed, the bell will be won and 9 medals will be paid out, and for Push Order Bell_RCL1-3, the correct operation is RCL operation, and if RCL operation is performed, the bell will be won and 9 medals will be paid out.

[0603] On the other hand, for example, if the common bell is internally selected in the winning role internal lottery, the bell wins regardless of the operation, and nine medals are paid out. Hereinafter, the above-mentioned push order bells_CLR1-3, push order bells_CRL1-3, push order bells_RLC1-3, and push order bells_RCL1-3 will be collectively referred to as "push order bells." Of these "push order bells," push order bells_CLR1-3 and push order bells_CRL1-3 will be referred to as "middle first bells" for ease of explanation, and push order bells_RLC1-3 and push order bells_RCL1-3 will be referred to as "right first bells." Furthermore, the number of common bells paid out is set to nine, the same as the push order bells, but this is not limited to this, and the number may be fewer than the push order bells. By reducing the number of common bells, medal payouts under normal conditions can be reduced.

[0604] In this embodiment, there is no push order bell where the correct answer is an LCR operation or an LRC operation (forward push or forward sandwich), but there is a push order bell where the correct answer is a CLR operation or a CRL operation (middle push) and an RLC operation or an RCL operation (reverse push or reverse sandwich). In other words, this is a specification called a biased bell. By using a biased bell, the number of balls released in the normal state (non-AT state) can be reduced and the number of balls released in the AT state can be increased. Note that a biased bell is a specification where a push order other than the first left stop is more advantageous for play than the first left stop (for example, the number of payouts is greater or the probability of winning is higher).

[0605] The display mode and payout amount for each operation when the internal winning combination (condition device) is 1-coin combination 1-8 and replay 1-7 are as shown in Figure 32(b). "S Blue 7 / BAR" in Figure 32(b) means that the "Blue Seven 1" symbol will line up on a single (1-line) winning line, or the "BAR" symbol will line up. "Fake" means that even if the target symbol is announced and you press the button, the announced symbol will not line up. "Replay (Peach 7 / W Blue 7 Fake)" means that you are informed to aim for the Pink Seven symbol or the Blue Seven symbol on a double (2-line) winning line, but the replay symbol will line up even if you press the button.

[0606] <Winning hand data> Next, the winning combination data stored in the ROM 306 of the main control unit 300 will be described.

[0607] FIG. 33 is a diagram showing winning combination data stored in the ROM 306 of the main control unit 300.

[0608] The winning combination information on the left side of Figure 33 is the same as the winning combination information shown in Figure 32(a). The push order combination, Bell (Push Order Bell), has four patterns (CLR, CRL, RLC, RCL) with different stop operation modes (push order). Furthermore, three combinations (1 to 3) are prepared for each pattern.

[0609] In other words, three possible combinations are prepared for each button press. For combinations with the same button press, the player's profit is the same, but by providing three combinations, the results can be more varied. For example, if there was only one combination for one button press, only specific combinations would be displayed for a specific button press, which would result in monotony. However, by providing multiple combinations for one button press, different combinations can be displayed for the same button press, preventing the results from becoming monotonous.

[0610] Each winning combination is assigned a consecutive natural number (winning combination number) such as "00" to "34" that corresponds one-to-one with the winning combination.

[0611] In the explanation so far, the transition from the non-advantageous zone to the advantageous zone was made by winning a combination other than a losing combination. In other words, if you win an internal combination of "01" or higher, which corresponds to Replay 3, you will move to the advantageous zone.

[0612] Gaming machines with advantageous zones require further innovation in the advantageous zone transition process. In this example, if an internal win occurs with a combination of "04" or higher associated with Repla...
