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

[0011] 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 being opened and closed relative to the main body 101. Three reels (left reel 110, center reel 111, right reel 112) with a variety of patterns arranged on the outer periphery 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 rotated by a driving device such as a stepping motor.

[0012] In this embodiment, an appropriate number of symbols are printed at equal intervals on a belt-shaped member, and the belt-shaped member is attached to a predetermined circular cylindrical frame material to form each of the reels 110-112 (see FIG. 25). When viewed from the player, the symbols on the reels 110-112 are displayed vertically in roughly threes through a symbol display window 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 seen by the player changes. In other words, each of the reels 110-112 functions as a display device that variably displays a combination of a plurality of 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 a display device. 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] In the slot machine 100, 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 110-112, 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 the optical sensor. Based on the detection result of this sensor, the position of the symbol on the reel in the rotation direction is determined, and the reels 110-112 are stopped so that the target symbol is displayed on the winning line.

[0015] A reel backlight 264 (see Fig. 6(a) and Fig. 7; details will be described later) is disposed on the back of the reels 110-112 for illuminating each symbol displayed in the symbol display window 113. In addition, a status display LED 280 (see Fig. 3; details will be described later) is disposed below the reels 110-112 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 operation 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 operation 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 operation 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) from 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. The operation of the start lever 135 is called the 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 light-emitting bodies 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 bodies can be turned on to notify the player.

[0021] Hereinafter, operations on stop buttons 137 to 139 are referred to as stop operations, with the first stop operation being referred to as the first stop operation (hereinafter also referred to as the "1st stop" or "1st stop"), the next stop operation being referred to as the second stop operation (hereinafter also referred to as the "2nd stop" or "2nd stop"), and the final stop operation being referred to as the third stop operation (hereinafter also referred to as the "3rd stop" or "3rd stop").

[0022] The reels that are stopped in response to these stop operations are called 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 called the operation order (or push order).

[0023] The operation sequences (pressing order) of the stop buttons 137 to 139, if 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 → middle → right operation sequence (left center right or LCR), (2) left → right → middle operation sequence (left right center or LRC), (3) middle → left → right operation sequence (middle left right or CLR), (4) middle → right → left operation sequence (middle right left or CRL), (5) right → left → middle operation sequence (right left center or RLC), and (6) right → middle → left operation sequence (right center left or RCL).

[0024] The medal return button 133 is a button for removing medals that have been inserted and become clogged by pressing it. The settlement button 134 is a button for settling medals electronically stored in the slot machine 100 and medals that have been bet, and discharging them from the medal payout outlet 155. The door key hole 140 is a hole for inserting a key for unlocking 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. A sound hole 181 is a hole for outputting sound from a speaker provided inside the slot machine 100 to the outside. Side lamps 144 provided on the left and right parts 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 rear side 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 on the front (player side) of the slot machine 100.

[0027] It should be noted that the display device does not have to be a liquid crystal display device, and may be any display device capable of displaying various performance images and various game information, such as 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. The display screen is rectangular and configured so that the player can view the entire screen. In this embodiment, the display screen is rectangular, but it may be square. Also, a decoration (not shown) may be provided on the periphery of the display screen, so that part of the periphery of the display screen is hidden by the decoration, making the display screen look irregular. In this embodiment, the display screen is flat, but it may be curved.

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

[0029] <Winning Line> Next, the pay lines will be described with reference to Fig. 2. Fig. 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 110-112 are displayed vertically in roughly threes through symbol display windows 113 provided in front of each of the reels 110-112, so that a total of nine symbols are visible.

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

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

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

[0034] In this embodiment, the only winning line provided is a middle winning line L1 (hereinafter sometimes simply referred to as "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 stopping 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 is effective (hereinafter, may be simply referred to as an "effective line") is predetermined according to the number of medals bet as a gaming medium.

[0036] The slot machine 100 of this embodiment is a three-coin bet-only machine, and when the number of medals inserted 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 player can start playing by operating the start lever 135.

[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, that is, 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, a total of three lines may be set as valid winning lines: an upper winning line consisting of the upper symbols of the left reel, the upper symbols of the middle reel, and the upper symbols of the right reel, and a lower winning line consisting of the lower symbols of the left reel, the lower symbols of the middle reel, and the lower symbols of the right reel. Alternatively, a number of winning lines according 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 constituting the status display LED 280.

And, among the plurality of LEDs 286 (second light-emitting means) constituting the stored number display unit 125, when the LED 286 (second light-emitting means) corresponding to the character sheet 282 of "CREDIT" is turned on, the character string "CREDIT" is lit, 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 illuminated member) constituting the payout number display unit 127. Then, among the multiple 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 shown by a dotted line in FIG. 4 where a dark coating film is formed) on the mounting surface of the LED board 288 (first board), a reflector 284 (first partitioning member) which partitions an opening 284c (space) having a shape of a 4-digit 7-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 7-segment display smaller than the opening 284b. Also, the multiple LEDs 286 constituting the gaming information display unit 126 are configured to be denser (the spacing between adjacent LEDs is narrower) than the multiple LEDs 286 constituting the stored number display unit 125 and the payout number display unit 127, so that the gaming information display unit 126 is configured as a smaller light-emitting area than the stored number display unit 125 and the payout 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, and dark blue.

[0061] In addition, 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 corresponding 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 a different color may be defined as the "first region" according to the present invention, or the region on the LED substrate 288 corresponding to the opening 284c may be defined as the "first region" according to the present invention.

[0062] A semi-transparent member having a shape of a 4-digit 7-segment display corresponding to the opening 284c is arranged on the character sheet 282 (first irradiated 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, the internal information of the slot machine 100 (for example, setting values, error codes, etc.) and the command monitor information can be displayed as numerical values.

[0063] According to this example, the multiple LEDs 286 (first light-emitting means) constituting the game information display unit 126 are arranged in the dark area 288b (first area, area where a dark coating film is formed) on the mounting surface of the LED board 288 (first board), so that it is possible to prevent a part of the LEDs 286 (first light-emitting means) from being reflected by light (external light) entering from the outside, and to prevent the LEDs 286 (first light-emitting means) from appearing as if they are lit when they are turned off, and it is possible to provide accurate game information to the player and to avoid giving the player disadvantages. In addition, it is possible to make the weak lighting (ghost lighting) of the LEDs 286 (first light-emitting means) due to a weak current when the LEDs are turned off less noticeable, and it is possible to avoid a situation where the player is misled by an erroneous display.

[0064] Furthermore, the multiple LEDs 286 (first light-emitting means) constituting the game information display unit 126 are light-emitting means constituting a notification means for notifying information (e.g., push order) corresponding to advantageous operation modes for the stop operation means (e.g., stop buttons 137 to 139) capable of stopping the reels. This makes it possible to prevent a misunderstanding that an operation mode is being notified when it is not being notified, 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 constitute the game information display unit 126 are light-emitting means that constitute a notification means that notifies information corresponding to an error (e.g., an error code), so that it is possible to prevent the misunderstanding that an error is being notified when no error is being notified, it is possible to provide accurate information to the player, and it is possible to 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 capable of emitting light in a first state (e.g., AT state or error state), and the multiple LEDs 286 (second light-emitting means) of the stored number display unit 125 and the payout number display unit 127 are light-emitting means capable of emitting light in a second state (e.g., storing or paying out medals), and the multiple LEDs 286 (second light-emitting means) constituting the stored number display unit 125 (second light-emitting means) and the payout number display unit 127 are arranged in a light-colored area 288a (second area; area where a light-colored coating is formed) coated with white coating silk.

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

[0069] In contrast, the AT state and error state are states that occur due to specific conditions that occur during play or when play is possible, so 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 number display unit 125 and the payout number display unit 127 are configured to continue to be lit, so that it can be said that the light emission frequency of the stored number display unit 125 and the payout number display unit 127 is higher than that of the game information display unit 126.

[0070] This improves the visibility of the LED 286 (second light-emitting means) of the stored coin count display unit 125 (second light-emitting means) and the payout coin count 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 the player.

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

[0072] According to this example, it is possible to prevent the LED 286 (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 LED 286 (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 LED 286 (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] In addition, the status indication 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. Therefore, the light emission mode (brightness, etc.) of the LED 286 can be changed by simply 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 indication LED 280, making it easy to change the specifications of the gaming machine, etc.

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

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

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

[0078] <Status display LED / unitization> FIG. 5 is a cross-sectional view of the status indicator LED 280 including the thermal crimp portion 284d of the reflector 284. As shown in FIG.

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

[0080] Reflector 284 is configured to have multiple types of openings 284a to 284c described with reference to Fig. 4, and thermal crimping portion 284d. Thermal crimping 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 thermal crimping portion 284d after it has been deformed by heating).

[0081] After the thermal crimping portion 284c of the reflector 284 is inserted 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, so that a deformed portion 284d2 having an outer diameter w6 (w6>w5) larger than the inner diameter w5 of the thermal crimping portion 284d of the LED substrate 288 is formed at the tip of the thermal crimping portion 284d.

[0082] As a result, the reflector 284 is fixed by caulking to the mounting surface of the LED board 288, and the reflector 284 and the LED board 288 are integrated. The character sheet 282 is disposed 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, reflector 284 (first partitioning member) is riveted to the mounting surface of LED board 288 (first board), and character sheet 282 (first irradiated member) is attached to reflector 284 (first partitioning member), whereby LED board 288 (first board), reflector 284 (first partitioning member), and character sheet 282 (first irradiated member) are unitized.

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

[0085] In this example, the deformation portion 284d2 is formed at a position protruding from the rear surface of the substrate 288 by a height h5, providing a play (gap) between the reflector 284 and the LED substrate 288, but the deformation portion 284d2 may be adhered closely to the rear surface of the LED substrate 288.

[0086] <Internal structure> Next, the internal structure of the slot machine 100 will be described with reference to Figure 6. Figure 6(a) is a front view showing the slot machine 100 with the front door 102 open, and Figure 6(b) is a side cross-sectional view of the slot machine 100.

[0087] Main body 101 is a box that opens at the front. Inside main body 101, there is arranged a main board storage case 640 (see FIG. 12, which will be described later in detail) that stores a main control board 600 (first board, which will be described later in detail), and below this main board storage case 640, three reels 110 to 112 are arranged. To the side of main board storage case 640 and reels 110 to 112, i.e., on the left side as viewed from the front, there is arranged a sub-control board storage case 220 that stores a sub-control board 650 (second board, which will be described later in detail).

[0088] Below, a medal payout device 180 (a device that pays out medals accumulated in a bucket) is provided, and above this medal payout device 180, i.e., below the reels 110 to 112, a power supply device (not shown) having a power supply board and the like are provided. The power supply device converts AC power supplied from the outside to the slot machine 100 into DC, converts it to a predetermined voltage, and supplies it to each control unit and each device, such as the main control unit 300, sub control units 400, 500, which will be described later. Furthermore, it is provided with a storage circuit (e.g., a capacitor) for supplying power to predetermined parts (e.g., the RAM 308 of the main control unit 300, etc.) for a predetermined period (e.g., 10 days) even after the external power supply is cut off.

[0089] An auxiliary medal storage 240 is disposed to the right of the medal payout device 180, behind which an overflow terminal is disposed (not shown).

[0090] 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 illumination 250 (described in detail 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 the medals pass when the medal selector 170 drops illegal medals, etc. into the medal receiving tray 161, etc.

[0091] <Reel front lighting> Next, the pre-reel lighting 250 will be described with reference to FIGS.

[0092] The reel front lighting 250 is a light-emitting means that illuminates (lights) the reel bands of each reel 110-112 (only the reel band 111a of the middle reel 111 is shown in Figure 6 (b)) from the front side (front surface), and in this example, is disposed above the pattern display window 113 on the back surface of the front door 102 so as to face the reel bands of the reels 110-112.

[0093] In this example, the reel front lighting 250 is configured with multiple 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 arranged in front of these LEDs.

[0094] In addition, 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 a granular manner on the reel band 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 reduce the visibility of the reels 110-112. Therefore, it is preferable to cover the front of the LEDs with a lens cover made of a colored transparent material.

[0095] 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 below 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.

[0096] In this way, 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 has a greater distance to the reel band than the reel front lighting 250, and has a distance over which the light emitted from the LED can be diffused. In addition, the light can be sufficiently diffused by the reflector 266 described below, so no lens cover is provided.

[0097] <Reel backlight> Next, the reel backlight 264 will be described with reference to FIG. 6(b) and FIG.

[0098] The slot machine 100 in this example is configured to include a left reel device (not shown) having a left reel 110, a center reel device 260 (see FIG. 6(b)) having a center reel 111, a right reel device (not shown) having a right reel 112, and a reel frame 262 (see FIG. 6(b)) capable of housing these three reel devices therein.

[0099] In addition, since the structures of the left and right reel devices of the slot machine 100 of this embodiment are the same as the structure of the center reel device 260, only the center reel device 260 will be described here, and descriptions of the left and right reel devices will be omitted.

[0100] 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 (illuminates) the reel band 111a (second illuminated member) of the middle reel 111 from the rear side (back surface), and a reel detection unit (not shown) for detecting the rotational position of the middle reel 111.

[0101] The center reel 111 is configured to include a reel band 111a on which multiple types of patterns 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.

[0102] FIG. 7(a) is a front view of the reel backlight 264, FIG. 7(b) is a side view of the reel backlight 264, and FIG. 7(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.

[0103] 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 plate 270 that is disposed on the side surface of the reflector 266.

[0104] The reflector 266 of the reel backlight 264 in this example is formed of white plastic, but the material of the reflector 266 of the reel backlight 264 is not particularly limited, and may be metal or the like, or may be a material of another color.

[0105] The reflector 266 is a component that defines a space through which light from multiple 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.

[0106] 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 is formed) on the mounting surface of the illumination board 268, where white coating silk is applied.

[0107] The openings 266a-266c and LEDs 268a of the reflector 266 included in the center reel device 260 are disposed 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 center reel device 260. With this structure, the back surface of the reel band 111a (second irradiated member) of the center reel 111 is irradiated with light from the multiple LEDs 268a (light emitting means).

[0108] The openings 266a-266c and the LEDs 266a of the reflector 266 of the left reel unit (not shown) are disposed 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, the back surface of the reel band (second irradiated member) of the left reel 110 is irradiated with light from the multiple LEDs 268a (light emitting means).

[0109] The openings 266a-266c and LEDs 268a of the reflector 266 of the right reel unit (not shown) are disposed 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, the back surface of the reel band (second irradiated member) of the right reel 112 is irradiated with light from the multiple LEDs 268a (light emitting means).

[0110] 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 the other openings. This allows the light to be uniformly irradiated to each of the multiple pattern positions of the pattern display window 113.

[0111] For example, by turning on all the LEDs 268a, all 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.

[0112] In this example, a plurality of slits (grooves) 266d to 266g are provided at predetermined intervals on the bottom surface of the upper opening 266a, the top and bottom surfaces of the central opening 266b, and the top surface of the lower opening 266c in the reflector 266. This allows the light emitted from the LED 268a to be uniformly irradiated onto the pattern located in front, improving the visibility of the pattern.

[0113] In addition, 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 such that the areas where the slits are formed and the areas where the slits are not formed alternate in the vertical direction (the positions of the slits do not coincide above and below the partitions of the openings). With this structure, it is configured so that light emitted from adjacent openings through the slits does not interfere with each other.

[0114] Since the reel backlight 264 can sufficiently and uniformly illuminate the reel band by the reflector 266 and the slits (grooves) 266d to 266g, it does not have a lens cover like the reel front lighting 250, but it may have a lens cover. This allows the reel band to be illuminated uniformly, and furthermore, since the reel backlight 264 is not directly viewed during reel assembly or maintenance of the gaming machine, glare for workers can be reduced.

[0115] <Differences between status display LED and 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. 6 and 7 will be described.

[0116] First, focusing on the light-emitting means and irradiated 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 irradiated member) shown in FIG. 6(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 irradiated member) shown in FIG. 5 (L1>L2).

[0117] Next, focusing on the partitioning members of the status display LED 280 and the reel backlight 264, the size (opening area) of the openings 266a-266c (partitioned space) of the reflector 266 (second partitioning member) in the reel backlight 264 shown in FIG. 6(a) is larger than the size (opening area) of the openings 284a-284c (partitioned space) of the reflector 280 (first partitioning member) in the status display LED 280 shown in FIG. 4.

[0118] According to this example, the shortest distance L1 from the LEDs 268a (second light-emitting means) in the reel backlight 264 to the reel band (second irradiated member) is longer than the shortest distance L2 from the LEDs 286 (first light-emitting means) in the status display LED 280 to the character sheet 282 (first irradiated member) (L1>L2), the openings 266a-266c (partitioned space) of the reflector 266 (second partitioning member) in the reel backlight 264 are larger than the openings 284a-284c (partitioned space) of the reflector 280 (first partitioning member) in the status display LED 280, and the LEDs 268a are disposed in the light-colored area 268d (area where a light-colored coating is formed) on the mounting surface of the illumination board 268 where white coating silk is applied, so that the light emission of the reel band (second irradiated member) can be made conspicuous while suppressing point light on the reel band (second irradiated member).

[0119] 8(a) is a front view of the LED board 288 of the status display LED 280, and FIG. 8(b) is a front view of the illumination board 268 of the reel backlight 264. FIG.

[0120] As shown in FIG. 8(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.

[0121] On the other hand, as shown in FIG. 8(b), on the illumination board 268 (second board) of the reel backlight 264, a plurality of LEDs 268a having a large illumination range and illumination distance to the second irradiated member (reel band) are arranged at predetermined intervals, and since there is a relatively large free space on the mounting surface of the illumination board 268, 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 of the LEDs 268a are printed.

[0122] The mounting surface of the illumination 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 other than white (cream in this example). This makes it possible to easily view the identification information 268b and the component mark 268c, and also allows the LED 268a to be mounted in the correct location.

[0123] Furthermore, since the identification information 268b is printed in a position visible from the front side through the openings 266a-266c (partitioned space) of the reflector 266 (second partition 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 arcade staff and the ease of maintenance of the light-emitting means.

[0124] <Status display LED and reel backlight / 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 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 includes a first light-emitting means (for example, the LED 286 of the game information display unit 126 shown in FIG. 4) capable of emitting 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 disposed in a first region on the mounting surface of the first board, the first region is a region in which a dark coating film is formed (for example, the dark region 288b shown in FIG. 4 where a black coating film resist is applied), and the dark coating film is a coating film of a dark color different from green.

[0125] According to the gaming machine of this embodiment, the first light-emitting means is disposed in an area where a dark coating is formed on the mounting surface of the first board, so that it is possible to prevent a part of the first light-emitting means from being reflected by light (external light) entering from the outside, and to prevent the first light-emitting means from appearing to be lit when it is turned off, and it is possible to provide accurate game information to the player and to avoid causing a 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 turned off less noticeable, and it is possible to avoid a situation where a false display misleads the player.

[0126] Gaming establishments vary in environment, but if the lighting inside the establishment is bright, the lighting in the establishment may make it difficult to see the displays on various displays, or they may appear to be lit when they are not, which may lead to misinterpretation by players and gaming establishment staff. However, with the gaming machine of this embodiment, it is possible to prevent misinterpretation of the displays due to reflections from the lighting in the establishment.

[0127] The reel may also be provided with a stop operation means (e.g., stop buttons 137-139 shown in FIG. 1) capable of stopping a reel (e.g., reels 110-112 shown in FIG. 1), the first state being a state for notifying 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 constituting a notification means for notifying information corresponding to the advantageous operation mode.

[0128] With such a configuration, it is possible to prevent a misunderstanding that an operation mode is being notified when it is not, and it is possible to provide accurate information to the player, thereby avoiding causing any disadvantage to the player.

[0129] 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).

[0130] With this configuration, it is possible to prevent the misunderstanding that an error has been notified when no error has been notified, and it is possible to provide accurate information to the player, thereby avoiding causing any disadvantage to the player.

[0131] Further, 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 FIG. 4) that can emit light in a second state (for example, a state in which medals are stored, a state in which medals are being dispensed), 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, the second region being a region in which a light-colored coating is formed (for example, light-colored region 288a shown in FIG. 4 where white coating silk is applied), the second region being 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.

[0132] Furthermore, the multiple 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 stored, a state in which medals are being dispensed), 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, the second region being a region in which a light-colored coating is formed (for example, light-colored region 288a shown in Figure 4 where white coating silk is applied), and the frequency with which the second state is reached may be higher than the frequency with which the first state is reached.

[0133] With this configuration, it is possible to improve the visibility of the second light-emitting means which emits light frequently (the display is updated frequently), and it is possible to improve convenience for the player.

[0134] The first region may be a region sandwiched between the second region on both sides.

[0135] 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.

[0136] The light emitting device 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), the first partitioning member being a member that partitions a space through which light from the multiple light emitting means mounted on the first substrate passes (e.g., openings 284a to 284c shown in Figure 7(b)), the first partitioning member being fixed to the first substrate by crimping (e.g., fixed by thermal crimping portion 284d shown in Figure 5), the first irradiated member being a member that is irradiated with light from the multiple light emitting means mounted on the first substrate, the first irradiated member being attached to the first partitioning member, and the first substrate, the first partitioning member, and the first irradiated member being unitized.

[0137] With this configuration, it is possible to facilitate replacement of the unitized first substrate, first partition member, and first irradiated member, as well as assembly into the gaming machine, thereby improving work efficiency.

[0138] The present invention also includes a second substrate (e.g., an illumination substrate 268 shown in FIG. 6(b) and FIG. 7(c)), a second partitioning member (e.g., a reflector 266 shown in FIG. 6(b) and FIG. 7(c)), and a second irradiated member (e.g., a reel strip 111a shown in FIG. 6(a), a lens cover, and a panel), the second substrate is a substrate on which the plurality of light-emitting means (e.g., an LED 268a shown in FIG. 7(c)) are mounted, the second partitioning member is a member in which a space through which light from the plurality of light-emitting means mounted on the second substrate passes (e.g., openings 266a to 266c shown in FIG. 7(b)) is partitioned, the second irradiated member is a member onto which light from the plurality of light-emitting means mounted on the second substrate is irradiated, and the shortest distance from the plurality of light-emitting means mounted on the second substrate to the second irradiated member is defined. The distance (e.g., the shortest distance L1 shown in FIG. 6(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 board 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 openings 266a to 266c shown in FIG. 7(b)) (the area of ​​the openings) is larger than the partitioned space in the first partitioning member (e.g., the openings 284a to 284c shown in FIG. 7(b)) (the area of ​​the openings), and the region on the mounting surface of the second board 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. 8(b) coated with white coating film silk) is formed.

[0139] 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.

[0140] Furthermore, the second substrate is a substrate that is detachable from the second partition member, and identification information corresponding to each of the plurality of light-emitting means on the mounting surface of the second substrate (e.g., identification information 268b shown in Figure 8(b)) is displayed on the mounting surface of the second substrate, and the identification information may be visible through the partitioned space in the second partition member.

[0141] With this configuration, if a malfunction occurs in the light-emitting means, the identification information corresponding to the light-emitting means with the malfunction can be easily identified, thereby improving convenience and maintainability.

[0142] <Control Unit> Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to Figure 9. Note that Figure 9 shows a circuit block diagram of the control unit.

[0143] The control unit of the slot machine 100 is broadly composed of a main control unit 300 that mainly controls game play, 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.

[0144] <Main control unit> First, the main control unit 300 of the slot machine 100 will be described. The main control unit 300 includes a basic circuit 302 that controls the entire main control unit 300, and the basic circuit 302 includes a CPU 304, a ROM 306 for storing control program data, lottery data used during internal lottery of winning combinations, and reel stop positions, a RAM 308 for temporarily storing data, an I / O 310 for controlling input and output of various devices, a counter timer 312 for measuring time, number of times, 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 the second sub-control unit 500 described later.

[0145] The CPU 304 of the basic circuit 302 operates by inputting a clock signal with a predetermined period output by the crystal oscillator 315b as a system clock. Furthermore, when the power is turned on, the CPU 304 transmits data for frequency division stored in a predetermined area of ​​the ROM 306 to the counter timer 312, and the counter timer 312 determines an interrupt time based on the received data for frequency division and transmits an interrupt request to the CPU 304 for each interrupt time. The CPU 304 monitors each sensor and transmits a drive pulse in response to the 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 of the ROM 306 is set to 47, the reference time for interrupt is 256×47÷8 MHz=1.504 ms.

[0146] 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 numerical value 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 the 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 control unit main processing described later).

[0147] The random number generation circuit 316 generates random numbers used in the basic circuit 302. There are two main methods for generating random numbers in the random number generation circuit 316: a counter mode and a random number mode. In the counter mode, a number that counts up (down) at a predetermined time interval is acquired, and the number is derived as a random number. There are two further methods in the random number mode. In the first method in the random number mode, a seed of a random number is used to perform a calculation using a predetermined function (e.g., a modulus function), and the result of this calculation is derived as a random number. In the second method, a number is read from a random number table in which numbers in the range of 0 to 65535 are randomly arranged, and the read number is derived as a random number. In the random number generation circuit 316, an irregular value is acquired by using white noise superimposed on a signal 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.

[0148] 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.

[0149] 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. The random number generation circuit 316 that receives this signal latches the value at that timing and stores it in a register that stores random numbers to be used in the lottery.

[0150] Two medal acceptance sensors are installed in the internal passage of the medal insertion port 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. The stop button 137 sensor, the stop button 138 sensor, and the stop button 139 are installed on each of the stop buttons 137 to 139, and detect the operation of the stop button by the player.

[0151] The bet button 130 sensor, bet button 131 sensor, and bet button 132 sensor are provided on the medal insertion buttons 130 to 132, respectively, and detect the insertion operation when medals electronically stored in the 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 paid out by the medal payout device 180. Each of the above sensors may be a non-contact sensor or a contact sensor.

[0152] 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 become 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.

[0153] 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 a 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 display unit 126, and the number of medals paid out indicator 127.

[0154] 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.

[0155] 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 supply 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).

[0156] The main control unit 300 also has 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.

[0157] <Sub-control section> 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 the control commands. The basic circuit 402 includes a CPU 404, a RAM 408 for temporarily storing data, an I / O 410 for controlling 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 inputting 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.

[0158] 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.

[0159] The first sub-control unit 400 is also provided with a sound source IC 418, which is provided with speakers 272, 277 via an output interface. The sound source IC 418 controls the amplifier and the sound output from the 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 sound data acquired from this ROM is amplified by the amplifier and output from the speakers 272, 277.

[0160] The first sub-controller 400 is also 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.

[0161] The first sub-controller 400 is also provided with 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. The 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.

[0162] 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 a performance button sensor 430 capable of detecting the pressing operation of the performance button 156. The CPU 404 monitors the states of the shutter sensor 428 and the performance button sensor 430 at each interrupt time.

[0163] 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).

[0164] 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, and this basic circuit 502 is equipped with a CPU 504, a RAM 508 for temporarily storing data, an I / O 510 for controlling 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.

[0165] 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.

[0166] The second sub-control unit 500 is also provided with a VDP 516 (video display processor), to which the ROM 506 and VRAM 518 are connected via a bus. The VDP 516 reads out image data and the like stored in the ROM 506 based on a signal 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.

[0167] <Main control board> Next, the main control board 600 (first board) will be described with reference to Fig. 10. Fig. 10(a) is a plan view of the main control board 600 before the identification board 610 is separated, and Fig. 10(b) is a plan view of the main control board 600 after the identification board 610 is separated.

[0168] 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. 9, or may be another board mounted on the gaming machine. In addition, the gaming machine may be equipped with multiple boards equivalent to the "first board."

[0169] The main control board 600 is configured to include a base material 602 made of a rectangular plate-like body, a 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 base material 602, a plurality of types of components 606 mounted on one surface of the base material 602, identification information 608 printed in a predetermined area (an area where the pattern wiring and resist layer 604 are not formed) on one surface of the base material 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 base material 602 to the end of the resist layer 604.

[0170] 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. Therefore, 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.

[0171] 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. In this example, the identification information 608 includes 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) printed on one side of the base material 602.

[0172] The "identification information" according to the present invention may be any identification information including information capable of identifying the manufacturer of the gaming machine. For example, it may be only the name of the manufacturer of the slot machine 100, or it may be identification information including 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 it may be identification information including information other than characters such as a two-dimensional code or a symbol.

[0173] <Main control board / board housing recess> Next, board accommodating recess 612 (recess of a first shape) of main control board 600 will be described.

[0174] A board accommodating recess 612 (a first-shaped recess) is formed on the right side surface (the short side on the right side when viewed from the front) of the main control board 600. The board accommodating recess 612 is large enough to accommodate the identification board 610 therein, and is cut inward from the short side on the right side of the main control board 600, forming an approximately inverted U-shape when viewed from the front.

[0175] Board accommodating recess 612 (first shape recess) is composed of two side walls 612a extending inward from the right short side of main control board 600, and a bottom surface 612b connecting these two side walls 612a.

[0176] 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.

[0177] 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 in a cuttable manner via a breaking portion 616.

[0178] 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).

[0179] 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 transported, etc., thereby improving convenience.

[0180] In addition, the "first shape recess" according to the present invention is not limited to the substrate accommodating recess 612 according to this embodiment. For example, the width w1 of the bottom surface 612b is shorter than the height h1 of the side wall 612a (w1

[0181] <Main control board / Identification board> Next, the identification board 610 of the main control board 600 will be described.

[0182] 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 (an area on which no pattern wiring or resist layer is formed) on one side of the base material 620.

[0183] The identification information 622 of the identification board 610 is identification information that includes information that can identify the manufacturer of the gaming machine. 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.

[0184] The "identification information" according to the present invention may be any identification information including information capable of identifying the manufacturer of the gaming machine. For example, it may be only the name of the manufacturer of the slot machine 100, or it may be identification information including 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 it may be information other than characters such as a two-dimensional code or a symbol.

[0185] <Main control board / fracture part> Next, the breakage portion 616 of the main control board 600 will be described.

[0186] ​As shown in FIG. 10(a), the breaking portion 616 is a portion where a plurality of slits (perforations) are formed at predetermined intervals at the connection 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 for making it easy to separate the identification board 610 from the base material 602 of the main control board 600.

[0187] By cutting the breaking portion 616 by hand (or with 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 FIG. 10(b).

[0188] As explained using FIG. 10(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), and therefore it is not possible to identify the manufacturer of the gaming machine.

[0189] However, as shown in FIG. 10(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.

[0190] When a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company results in increased manufacturing costs; however, according to 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 have any defects during assembly or inspection.

[0191] 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 employed. That is, any part that can separate the identification substrate from the base material of the main control substrate is acceptable.

[0192] <Main control board / Adapter accommodation recess> Next, the adapter accommodation recess 614 (recess of the second shape) of the main control board 600 will be described.

[0193] On the left side surface of the main control board 600 (the short side on the left 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 (recess of the second shape) that is substantially U-shaped in the front view and is cut inward from the short side on the left of the main control board 600 is formed.

[0194] The adapter accommodation recess 614 (recess of the second shape) is composed of two side walls 614a extending inward from the short side on the left of the main control board 600 and a bottom surface 614b connecting the two side walls 614a.

[0195] 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.

[0196] 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.

[0197] 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).

[0198] <Main control board / Board housing recess and adapter housing recess> Comparing the shapes of the board housing recess 612 (recess of the first shape) and the adapter housing recess 614 (recess of the second shape) on the main control board 600, as shown in Fig. 10(b), the height h1 of the side wall 612a of the board housing recess 612 is higher than the height h3 of the side wall 614a of the adapter housing recess 614 (h1 > h3), the width w1 of the bottom surface 612b of the board housing recess 612 is narrower than the width w3 of the bottom surface 614b of the adapter housing recess 614 (w1 < w3), and the board housing recess 612 and the adapter housing recess 614 have different shapes from each other.

[0199] 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 the installation of the board and preventing installation mistakes of the board.

[0200] In the manufacturing process of the game table, the board products in the state of being board products are covered with various board cases and installed, fixed, and attached in 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 although no installation mistakes occur, the installer may be confused about which board to install and waste working time. According to this example, it is easier to distinguish the boards, and the process during the manufacturing and assembly of the game table can be simplified.

[0201] Also, the height h1 of the side wall 612a of the board housing recess 612 (recess of the first shape) is higher than the height h3 of the side wall 614a of the adapter housing recess 614 (recess of the second shape) (h1 > h3), and the bottom surface 612b of the board housing 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 housing recess 614 (recess of the second shape). Therefore, it is easy to cut the identification board 610 housed in the board housing recess 612 (recess of the first shape), and the workability can be improved.

[0202] Next, focusing on the positional relationship between the board accommodating recess 612 (recess of first shape) and the resist layer 604 (first resist layer) of the main control board 600, 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 10 (b), the shortest distance x1 from the bottom surface 612b (fracture surface of the first shape) of the board 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).

[0203] 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 (the 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 (the longitudinal direction of the main control board 600) (x1>x2).

[0204] 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 substrate 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). This makes it possible to ensure a clearance (work space) from the substrate accommodating recess 612 (recess of the first shape) to the resist layer, making it easier to cut the fracture portion 616 formed in the substrate accommodating recess 612 (recess of the first shape), improving workability, and 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 touching the resistor layer or pattern wiring, thereby preventing damage to the main control substrate, etc.

[0205] Also, in this way, by making the shortest distance x1 from the end of the resist layer 604 at a location having no break portion 616 (for example, the adapter housing recess 614 (the recess of the second shape)) longer than the shortest distance x2 from the end of the resist layer 604 at a location having the break portion 616, it is possible to make it difficult for cracks to occur in the resist layer and the pattern wiring due to stress or strain during cutting from the break portion 616.

[0206] 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 or strain during cutting from the break portion 616, as shown in FIG. 10(b), the shortest distance x1 from the bottom surface 612b (the breaking surface of the first shape) of the substrate housing 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 housing recess 612 (the recess of the first shape) to the resist layer 604, the shortest distance x1 from the bottom surface 612b (the breaking surface of the first shape) of the substrate housing 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 having no recess of the second shape.

[0207] 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 at the time of cutting from the break portion 616, as shown in FIG. 10(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 not provided with the recess of the second shape.

[0208] 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).

[0209] 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).

[0210] According to this example, the shortest distance y1 from the side wall 612a of the board accommodating recess 612 (recess of 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 of second shape) to the resist layer 604 (first resist layer) (y1>y2). This makes it possible to ensure a clearance (work space) from the board accommodating recess 612 (recess of first shape) to the resist layer, making it easier to cut the breaking portion 616 formed in the board accommodating recess 612 (recess of first shape) and improving workability. In addition, even if a cutting operation is performed by placing fingers around the periphery of the board accommodating recess 612 (recess of first shape) or using a tool, it is possible to prevent fingers or tools from touching the resistor layer or pattern wiring, thereby preventing damage to the main control board.

[0211] Furthermore, by making the shortest distance y1 to the end of the resist layer 604 at a location that includes the break portion 616 longer than the shortest distance y2 to the end of the resist layer 604 at a location that does not include 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.

[0212] 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).

[0213] <Main control board / components> Next, the components 606 mounted on the main control board 600 will be described.

[0214] The components 606 mounted on the main control board 600 include the adapter 624 disposed 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, and an IC 606c.

[0215] In the example shown in FIG. 10(b), a plurality of passive components 606a (606a1, 606a2), an IC 606c, and the like are disposed near the board accommodating recess 612 of the main control board 600.

[0216] 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 a first shape).

[0217] According to this example, 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 board accommodating recess 612 (recess of first shape) (longitudinal direction of the identification board 610). Therefore, it is possible to reduce the effect that the stress applied in the longitudinal direction of the board accommodating recess 612 (recess of first shape) when cutting the breaking portion 616 has on the passive component 606a1 (first passive component) mounted on the main control board 600 (first board), and to prevent damage to the passive component 606a1 (first passive component).

[0218] 10B, a plurality of passive components 606a (606a1, 606a2), an IC 606c, and the like are also disposed near the adapter accommodating recess 614 of the main control board 600. As shown in FIG.

[0219] These passive components are axial components with leads extending from both ends of the main body as shown in Fig. 10. In addition, 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 the passive components, or control ICs included in the active components, and include components that have a long side and a short side.

[0220] Here, considering 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).

[0221] According to this example, the shortest distance x3 from the board 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 makes it possible to ensure a clearance (work space) from the board 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 board accommodating recess 612 (recess having a first shape), thereby improving workability. In addition, even when a cutting operation is performed by placing a finger around the board accommodating recess 612 (recess having a first shape) or by using a tool, it is possible to prevent the finger or tool from touching the passive component 606a1 (first passive component). This makes it possible to prevent damage to the passive component 606a1 (first passive component).

[0222] 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 breaking part, since the longitudinal direction of the component is orthogonal to the direction in which stress is applied during cutting, damage to the component can be prevented.

[0223] 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 satisfy "x3 < x4 < x3'", and it can be seen from FIG. 10 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 components parallel to the stress direction applied to the substrate are arranged at positions far from the breaking part. Note that, the shortest distance x3' is the distance of the 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 the oblique line from the substrate accommodation recess 612 to the passive component 606a2.

[0224] According to this example, the longitudinal direction of the passive component 606a2 (second passive component) is different from the substrate accommodation recess 612 (recess of the first shape), and the passive component 606a2 (second passive component) is likely to be affected by the stress applied in the longitudinal direction of the substrate accommodation recess 612 (recess of the first shape) when cutting the breaking part 616. However, by arranging the passive component 606a2 (second passive component) at a position farther from the substrate accommodation recess 612 (recess of the first shape) than the passive component 606a1 (first passive component), damage to the passive component 606a2 (second passive component) can be prevented.

[0225] 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 FIG. 10) 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.

[0226] <Main control board / fracture surface> Next, a cutaway view of main control board 600 will be described.

[0227] The outer edge of the base material 602 of the main control board 600 and the outer edge of the base material 620 of the identification board 610 have 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 a fracture surface (a fracture surface of a third shape) where a molding burr was generated.

[0228] 10(b), when the identification board 610 is separated from the base material 602 of the main control board 600, a burr (hereinafter, sometimes referred to as a "fracture burr") 632 generated 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, the main control board 600 and the identification board 610 after separation each become boards having a fracture surface (a fracture surface of a first shape) on which the burr 632 is generated in addition to a fracture surface (a fracture surface of a third shape) on which the burr is generated during molding.

[0229] 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 632 at the time of breaking are burrs with larger irregularities than the burrs at the time of molding, and the fracture surface on which the burrs at the time of molding have occurred (fracture surface of a third shape) has rougher irregularities (larger irregularities) than the fracture surface on which the burr 632 at the time of breaking has occurred (cross section of the first shape).

[0230] The fracture surface where the burr 632 occurred during breaking (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 located more inward of the main control board 600 than the fracture surface where the burr occurred during molding (fracture surface of the third shape).

[0231] According to this example, the fracture surface where the burr 632 occurred (fracture surface of the first shape) is located inside of the fracture surface where the burr occurred during molding (fracture surface of the third shape), so that a clearance (work space) from the recess of the first shape to the resist layer can be secured, and the fracture surface formed in the recess of the first shape can be easily cut, improving workability. Also, because the rough fracture surface is located inside the main control board, safety can be improved compared to the case where the rough fracture surface is exposed outside the main control board.

[0232] <Sub-control board (second board)> Next, the sub-control board 650 (second board) will be described with reference to Fig. 11. Fig. 11 is a plan view of the sub-control board 650.

[0233] 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. 9, or may be another board mounted on the gaming machine. In addition, the gaming machine may be equipped with multiple boards equivalent to the "second board."

[0234] The sub-control board 650 is composed of a base material 652 consisting of a rectangular plate-like 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.

[0235] <Sub-control board / fracture surface> Next, a broken surface of the sub-control board 650 will be described.

[0236] A portion of each of the longitudinal and lateral sides of the base material 652 of the sub-control board 650 has burrs 658 (hereinafter sometimes referred to as "molding burrs 658") caused by breakage due to 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) where the molding burr 658 has occurred, and a second fracture surface 650b where the molding burr 658 has not occurred.

[0237] It should be noted that the sub-control board 650 is a board that does not include a board equivalent to the identification board 610 included in the main control board 600, or a break portion equivalent to the break portion 616 included in the main control board 600.

[0238] Molding burr 658 of sub-control board 650 is a burr generated by breakage caused by 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). Molding burr 658 is a burr with smaller irregularities than fracture burr 632 (burr remaining 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 Fig. 10, and fracture surface 660 (fracture surface of second shape) where molding burr 658 has occurred has finer irregularities (smaller irregularities) than the fracture surface (cross section of first shape) where fracture burr 632 has occurred.

[0239] Here, focusing on the positional relationship between board accommodating recess 612 and resist layer 604 of main control board 600, and the positional relationship between first fracture surface 650a and resist layer 654 of sub-control board 650, the shortest distance x1 from bottom surface 612b of board accommodating recess 612 of main control board 600 to resist layer 604, as shown in Figure 10(b), is configured to be longer than the shortest distance x5 from first fracture surface 650a of sub-control board 650 to resist layer 654, as shown in Figure 11 (x1>x5).

[0240] 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 substrate 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 substrate 650 to the resist layer 654 (second resist layer) (x1>x5). This makes it possible to ensure a clearance (work space) from the substrate accommodating recess 612 (recess of the first shape) to the resist layer, making it easier to cut the fracture portion 616 formed in the substrate accommodating recess 612 (recess of the first shape). This improves workability. In addition, even if a cutting operation 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 touching the resistor layer or pattern wiring, thereby preventing damage to the main control substrate.

[0241] 11, 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, it is possible to prevent cracks from occurring in the resist layer when separating a waste board or adjacent boards during board molding.

[0242] <Main board storage case> Next, the configuration of the main board storage case 640 (642, 644) will be described with reference to FIGS.

[0243] FIG. 12 is an exploded oblique view showing main board storage case 640 and main control board 600, and FIG. 13(a) is a plan view of main board storage case 640 housing main control board 600, viewed from the board housing body 642 side.

[0244] FIG. 13(b) is a cross-sectional view taken along line AA in FIG. 13(a), and FIG. 13(c) is a cross-sectional view showing the structure of a conventional substrate corresponding to FIG. 13(b).

[0245] As shown in FIG. 12, the main substrate storage case 640 is a box-shaped body formed by combining a substrate container 642 (container) having a roughly rectangular corner-plate-shaped bottom surface and a lid 644 arranged to cover the internal space of this substrate container 642.

[0246] Main control board 600 is stored in the internal space of main board storage case 640, fixed to board housing body 642 by screws 646. Board housing body 642 and lid body 644 are each made of translucent resin, and main control board 600 stored inside main board storage case 640 can be viewed from the outside through main board storage case 640.

[0247] Gate-shaped hinge portions 642b are provided at two locations on the lower edge of the substrate housing 642. Hook-shaped hook portions 644a that engage with the hinge portions 642b are provided at two locations on the lower edge of the lid 644, and locking tongue pieces 644b that lock with the upper edge of the substrate housing 642 are provided at both left and right ends of the upper edge.

[0248] 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 housing body 642, and then the lid body 644 is swung around the hinge portion 642b to combine the board housing body 642 and the lid body 644, and the locking tongue piece 644b of the lid body 644 is engaged with the locking hole on the upper edge of the board housing body 642, thereby fixing the lid body 644 to the board housing body 642.

[0249] As shown in FIG. 12, 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 a position corresponding to the adapter accommodating recess 614 (recess of second shape) of the main control board 600, and as shown in FIG. 13(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 (recess of second shape) of the main control board 600.

[0250] According to this example, since the main board housing case 640 is provided with ribs 642a that can be fitted (abutted) into the adapter housing recess 614 (recess of the second shape) of the main control board 600 (first board), when housing the main control board 600 (first board), the main control board 600 (first board) can be housed in the correct position and in the correct orientation, preventing mistakes in mounting the board and the like. Moreover, after housing the main control board 600 (first board), since the main control board 600 (first board) can be securely held, 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.

[0251] Also, as described above, the board housing recess 612 and the adapter housing recess 614 of the main control board 600 have different shapes, and the width w1 of the bottom surface 612b of the board housing recess 612 is narrower than the width w3 of the bottom surface 614b of the adapter housing recess 614 (w1 < w3). Therefore, the two ribs 642a are structured such that they cannot be fitted to the two side walls 614a of the board housing recess 612 of the main control board 600.

[0252] According to this example, since the two ribs 642a of the board housing body 642 (housing body) cannot be fitted to the two side walls 614a of the board housing recess 612 (recess of the first shape) of the main control board 600, when housing the main control board 600, the main control board 600 can be housed in the correct position and in the correct orientation, preventing mistakes in mounting the board and the like.

[0253] On the other hand, as shown in FIG. 12, at the position corresponding to the board housing 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 housing body 642, no ribs or the like are provided. As shown in FIG. 13(a), in a state where the main control board 600 is housed in the board housing body 642, voids (spaces where nothing is provided, hereinafter also referred to as "void regions") are formed above and below the board housing recess 612 (recess of the first shape) of the main control board 600.

[0254] Therefore, as shown in Figure 13 (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 storage case 640.

[0255] The IC606c is a component disposed near the substrate accommodating recess 612 (recess having a first shape). The IC606c is also a component whose chip body can be fitted into a socket. The short side of the IC606c is visible from the gap region, but the IC606c may be disposed vertically so as to be visible from the long side. In this case, the substrate accommodating recess 612 (recess having a first shape) may be formed so that the entire long side of the IC606c is visible from the gap region, or the IC606c may be disposed so that the IC606c is visible from a part of the long side.

[0256] Also, other components may not be arranged between the IC 606c and the substrate accommodating recess 612 (recess of the first shape), and this makes it possible to avoid impeding visibility of the IC 606c from the gap region. If other components are arranged between the IC 606c and the substrate accommodating recess 612 (recess of the first shape), the other components are shorter than the IC 606c, thereby ensuring visibility from the gap region. In this case, although there is a possibility that the other components will be damaged when the identification substrate 610 is broken, damage to the IC 606c can be prevented, and the substrate can be identified as defective by the damage to the other components.

[0257] 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 the components mounted on the board can be confirmed while they are contained in the container, thereby improving maintainability and workability.

[0258] <Main control board / Summary> As described above, the gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (e.g., the main control board 600 shown in FIG. 10), the first board being a board having a recess of a first shape (e.g., the board accommodating recess 612 shown in FIG. 10), the first board being a board having a recess of a second shape (e.g., the adaptor accommodating recess 614 shown in FIG. 10), and the recess of the first shape and the recess of the second shape being different shapes.

[0259] 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, which improves workability when mounting the board and prevents mistakes in mounting the board. In this way, a gaming machine in which mistakes in mounting are suppressed can be provided.

[0260] In the manufacturing process of game machines, the circuit board products are covered with various circuit board cases and are installed, fixed, and attached inside the game machine. However, many circuit board products have similar external shapes, and installation mistakes can occur during the manufacturing and assembly of game machines, or, even if they do not result in installation mistakes, it can be difficult to know which circuit board to install, resulting in wasted work time. However, the game machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the process of manufacturing and assembling the game machine.

[0261] The container may also include a container (e.g., substrate container 642 shown in FIG. 13(b)) capable of storing the first substrate, and when the first substrate is stored in the container, a component (e.g., IC 606c shown in FIG. 13(b)) arranged on the first substrate may be visible through a recess of the first shape (e.g., substrate accommodating recess 612 shown in FIG. 13(b)).

[0262] With this configuration, the board (first board) can be easily viewed, and when an illegal component is attached, the illegal component can be easily found, 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.

[0263] In addition, the container may include a container (e.g., substrate container 642 shown in FIG. 13(a)) capable of storing the first substrate, and the container may include a protrusion therein (e.g., rib 642a shown in FIG. 13(a)), and the protrusion may be a portion that can fit into the recess of the second shape (e.g., adapter accommodating recess 614 shown in FIG. 13(a)) but cannot fit into the recess of the first shape (e.g., substrate accommodating recess 612 shown in FIG. 13(a)).

[0264] With this configuration, when the board (first board) is stored, the board can be stored in the correct position and in the correct orientation, which prevents operational errors, and after the board is stored, it can be held securely, which reduces wobbling of the board when inserting and removing a connector, etc. In this way, a gaming machine with improved operability during assembly and inspection can be provided.

[0265] In addition, the first substrate is a substrate that allows one manufacturer of the gaming machine to be identified by cutting a break portion (e.g., break portion 616 shown in Figure 10(a)), and the recess of the first shape may be the portion where the break portion is formed.

[0266] When a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company incurs 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 defects during assembly or inspection.

[0267] Furthermore, the first substrate may be a substrate having a plurality of components (e.g., passive components 606 such as resistors, capacitors, and coils as shown in FIG. 10), one of the plurality of components may be a first component (e.g., passive component 606a1 as shown in FIG. 10(b)) arranged in the vicinity of the recess of the first shape, and the longitudinal direction of the recess of the first shape (e.g., substrate accommodating recess 612 as shown in FIG. 10(b)) and the longitudinal direction of the first component may be the same direction.

[0268] With this configuration, it is possible to reduce the effect of the stress applied in the longitudinal direction of the recess of the first shape when the breaking portion is cut on the first passive component mounted on the first substrate, and to prevent damage to the first passive component. In this way, it is possible to provide a gaming machine in which defects due to damage to components are suppressed.

[0269] 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. 10, long and thin components, and components having terminals protruding from a main body), one of the plurality of components may be a first component arranged in the vicinity of the recess of the first shape (e.g., passive component 606a1 shown in FIG. 10(b)), one of the plurality of components may be a second component arranged in the vicinity of the recess of the second shape (e.g., passive component 606a2 shown in FIG. 10(b)), and the shortest distance from the recess of the first shape to the first component (e.g., shortest distance x3 shown in FIG. 10(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. 10(b)).

[0270] With this configuration, a clearance (work space) can be secured from the recess of the first shape to the first passive component, which makes it easier to cut the breakage portion formed in the recess of the first shape, and improves workability. In addition, even if the cutting work is performed by placing fingers around the periphery of the recess of the first shape or by using a tool, the fingers or the tool can be prevented from touching the first passive component, and damage to the first passive component can be prevented. In this way, a gaming machine can be provided that suppresses malfunctions due to damage to parts and improves the safety of the worker.

[0271] In addition, 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 (e.g., the shortest distance α shown in Figure 10(b)) may be longer than the shortest distance from the recess of the first shape to the first part (e.g., the shortest distance x3 shown in Figure 10(b)).

[0272] 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 malfunctions due to damage to components are suppressed.

[0273] Furthermore, the first substrate may be a substrate having a resist (e.g., resist layer 604 shown in FIG. 10), the first substrate may be a substrate having identification information (e.g., identification information 608 shown in FIG. 10) displayed in a predetermined area, the identification information being identification information including information capable of identifying one of the manufacturers of the gaming machine, and the predetermined area may be an area in which the resist is not formed.

[0274] 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.

[0275] The predetermined area may be an area where no pattern wiring is formed.

[0276] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0277] <Main control board and sub control board / Summary> As described above, the gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (e.g., the main control board 600 shown in FIG. 10) and a second board (e.g., the sub-control board 650 shown in FIG. 11), in which the first board is a board having a first shaped fracture surface (e.g., a fracture surface having a burr 632 at the time of fracture as shown in FIG. 10(b)), the second board is a board having a second shaped fracture surface (e.g., the first fracture surface 650a shown in FIG. 11), and the first shaped fracture surface and the second shaped fracture surface are different in shape.

[0278] According to the gaming machine of this embodiment, it is easy to distinguish between the first and second boards, the workability during installation of the boards can be improved, and installation errors of the boards can be prevented. In this way, it is possible to provide a gaming machine in which installation errors are suppressed.

[0279] In the manufacturing process of game machines, the circuit board products are covered with various circuit board cases and are installed, fixed, and attached inside the game machine. However, many circuit board products have similar external shapes, and installation mistakes can occur during the manufacturing and assembly of game machines, or, even if they do not result in installation mistakes, it can be difficult to know which circuit board to install, resulting in wasted work time. However, the game machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the process of manufacturing and assembling the game machine.

[0280] Furthermore, the first substrate may be a substrate having a first resist (e.g., resist layer 604 shown in FIG. 10), the second substrate may be a substrate having a second resist (e.g., resist layer 654 shown in FIG. 11), 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. 11), 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. 10(b)) 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. 10(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. 11).

[0281] With this configuration, a clearance (work space) can be secured from the recess of the first shape to the resist layer, which makes it easier to cut the breakage portion formed in the recess of the first shape, and improves workability. In addition, even if the cutting work is performed by placing fingers around the periphery of the recess of the first shape or by using a tool, the fingers or tool can be prevented from touching the resist layer or the pattern wiring, and damage to the main control board can be prevented. In this way, a gaming machine in which malfunctions due to damage to parts are suppressed can be provided.

[0282] Furthermore, the first substrate may be a substrate that allows one manufacturer of the gaming machine to be identified by cutting a break portion (e.g., break portion 616 shown in Figure 10(a)), and the second substrate may be a substrate that does not have the break portion, and the break surface of the first shape may be a break surface formed by cutting the break portion.

[0283] When a company has multiple affiliated companies, manufacturing a circuit board for each affiliated company incurs 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 defects during assembly or inspection.

[0284] Furthermore, the first substrate may be a substrate having a fracture surface of a third shape (e.g., a fracture surface where a burr has occurred during molding), the fracture surface of the third shape is a fracture surface formed during molding of the first substrate, the fracture surface of the first shape is rougher than the fracture surface of the third shape, and the fracture surface of the first shape may be a fracture surface located more inward than the fracture surface of the third shape in the first substrate.

[0285] With this configuration, a clearance (work space) can be secured between the recess of the first shape and the resist layer, making it easier to cut the fractured portion formed in the recess of the first shape, and improving workability. In addition, 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 malfunctions caused by breakage of parts and improves the safety of workers.

[0286] The fracture surface of the second shape may be a fracture surface that constitutes a part of one or more sides of the second substrate.

[0287] With this configuration, the shape of the second substrate can be simplified, and the degree of freedom in circuit design can be improved.

[0288] Furthermore, the first substrate may be a substrate having a first resist (e.g., resist layer 604 shown in FIG. 10), the first substrate may be a substrate having identification information (e.g., identification information 608 shown in FIG. 10) displayed in a predetermined area, the identification information being identification information including information capable of identifying one of the manufacturers of the gaming machine, and the predetermined area may be an area where the first resist is not formed.

[0289] 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.

[0290] The predetermined area may be an area where no pattern wiring is formed.

[0291] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0292] Further, a gaming machine according to the present embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first board (e.g., the main control board 600 shown in FIG. 10), the first board being a board having a cross-sectional portion of a predetermined shape (e.g., the broken portion 616 shown in FIG. 10(a)), the first board being a board having a cross-sectional portion of a specific shape (e.g., 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 of the main control board 600), the first board being a board having a first resist (e.g., the resist layer 604 shown in FIG. 10), and the first board being a board having a shortest distance from the cross-sectional portion of the predetermined shape to the first resist. the first substrate is a substrate in which the shortest distance from the cross-sectional portion of the specific shape to the first resist is a first distance (e.g., the shortest distance x1 shown in FIG. 10(b)), the first substrate is a substrate in which a shortest distance from the cross-sectional portion of the specific shape to the first resist is a second distance (e.g., the shortest distance z1 shown in FIG. 10(b)), the first substrate is a substrate in which a manufacturer of the gaming machine can be identified by cutting the 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 have different shapes, and the first distance is longer than the second distance.

[0293] According to the gaming machine of this embodiment, when the fractured portion is cut, the distortion caused by the stress applied to the board can be reduced, and damage to the board and the components mounted on the board can be prevented. In this way, a gaming machine in which defects caused by damage to components are suppressed can be provided.

[0294] In the manufacturing process of game machines, the circuit board products are covered with various circuit board cases and are installed, fixed, and attached inside the game machine. However, many circuit board products have similar external shapes, and installation mistakes can occur during the manufacturing and assembly of game machines, or, even if they do not result in installation mistakes, it can be difficult to know which circuit board to install, resulting in wasted work time. However, the game machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the process of manufacturing and assembling the game machine.

[0295] Furthermore, the first substrate may be a substrate having a first side (e.g., a long side), the first substrate may be a substrate having a cross-sectional portion of the specified 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.

[0296] With this configuration, it is possible to reduce distortion in the board due to stress applied to the board when the breaking portion is cut, thereby preventing damage to the board and components mounted on the board.

[0297] <Main Control Board According to Modification 1> Next, a main control board 670 (first board) according to the first modification will be described with reference to Fig. 14. Figs. 14(a) and (b) are plan views of the main control board 670 according to the first modification.

[0298] The main control board 670 of the first variant example is composed of a base material 672 consisting of a rectangular plate-like body, a pattern wiring (not shown) and a resist layer 674 (first resist layer) formed on one side of the base material 672, multiple types of components 676 mounted on one side of the base material 672, identification information 678 printed in a predetermined area (an area where the pattern wiring and resist layer 674 are not formed) on one side of the base material 672, and an identification board 680 having identification information 692 different from the identification information 678.

[0299] 10, an example was shown in which board accommodating recess 612 (recess of first shape) is formed on the right side surface (short side on the right side as 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 of first shape) of the same shape as board accommodating recess 612 (recess of first shape) of main control board 600 is formed on the lower side surface (long side on the lower side as viewed from the front) of main control board 670. Also, adapter accommodating recess 684 of the same shape as adapter accommodating recess 614 of main control board 600 is formed on the upper side surface (long side on the upper side as viewed from the front) of main control board 600.

[0300] The main control board can be applied even if it does not have the adaptor accommodating recess 684. Furthermore, the "first board" according to the present invention may be a peripheral board (board for performance) or a relay board instead of the main control board.

[0301] According to this example, board accommodating recess 682 (recess of a first shape) is formed on the long side of main control board 670 (first board), so that when breaking portion 696 is cut, distortion caused 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) can be reduced, and 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) can be prevented.

[0302] In the modified example, the direction in which the main control board 670 is stressed is the longitudinal direction, and the board accommodating recess 682 is provided along the longitudinal direction and arranged in a direction parallel to the stress direction. On the other hand, when the fractured portion is cut, a force acts in a direction different from the stress direction, so that distortion of the base material 672 can be suppressed when the fractured portion is cut.

[0303] Furthermore, if an attempt is made to forcibly remove main control board 670 (first board) from a main board storage case (for example, board housing body 642 shown in FIG. 12), 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, main control board 600 shown in FIG. 10(a)). This makes it possible to leave traces of tampering, etc., thereby improving crime prevention.

[0304] 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 14(a) with the resist layer 674 sandwiched between the substrate accommodating recess 682).

[0305] According to this example, since the distance from the identification information 692 of the identification board 680 is increased, 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.

[0306] <Main control board / components according to modification example 1> Next, components 676 mounted on main control board 670 according to the first modification will be described.

[0307] Components 676 implemented on 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.

[0308] In the example shown in FIGS. 14(a) and 14(b), a plurality of passive components 676a (676a1, 676a2), an IC 676c, and the like are disposed near a board accommodating recess 682 (a recess of a first shape) of a main control board 670.

[0309] 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 different direction 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.

[0310] 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 a first shape). Therefore, the effect of the stress applied in the longitudinal direction of the recess of the first shape when cutting the fracture portion on the first passive component mounted on the first substrate can be reduced, and damage to the first passive component can be prevented.

[0311] 14(a) and 14(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.

[0312] The longitudinal direction of one passive component 676a2 (second passive component) of the multiple passive components 676a is a direction different from the longitudinal direction of the adaptor accommodating recess 684 and is a direction perpendicular to the longitudinal direction of the adaptor accommodating recess 684.

[0313] Here, in FIG. 14(a), focusing 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).

[0314] According to this example, the shortest distance y3 from the board 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 board accommodating recess 682 (recess having a first shape) to the passive component 676a1 (first passive component) can be secured, and the broken portion formed in the board accommodating recess 682 (recess having a first shape) can be easily cut, improving workability. In addition, even when a cutting operation is performed by placing a finger around the periphery of the board 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 676a1 (first passive component), and thus it is possible to prevent damage to the passive component 676a1 (first passive component).

[0315] Also, the shortest distance y4 from the adapter accommodation recess 684 (the recess of the second shape) 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. 14(b)) from the passive component 676a2 (the second passive component) to the nearest long side on the main control board 670 is used, it may be set as "y3 > y4'", that is, when "the distance from the breakage part to the first passive component > the distance from the side without the breakage 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 component due to the stress at the time of cutting of the breakage part can be prevented.

[0316] Also, in Fig. 14(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).

[0317] Also, in Figs. 14(a) and (b), 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 component. 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.

[0318] According to this example, the shortest distance y5 from the board 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 board accommodating recess 682 (recess having a first shape) to the passive component 676a2 (second passive component) can be secured, and the broken portion formed in the board accommodating recess 682 (recess having a first shape) can be easily cut, improving workability. In addition, even when a cutting operation is performed by placing a finger around the periphery of the board 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) from occurring.

[0319] Also, the shortest distance from the adaptor accommodating recess 684 (recess of second shape) to the passive component 676a2 (second passive component) is set to y4, but even if there is no adaptor accommodating recess and the shortest distance from the long side closest to the passive component 676a2 (second passive component) in the main control board 670 is set to y4', "y5>y4'" may be satisfied. In other words, if a distance greater than y4 (y4') is secured and the passive component is arranged in a direction perpendicular to the longitudinal direction of the board accommodating recess, the effect of stress when the fracture portion is cut can be reduced and damage to the component can be prevented.

[0320] 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 14(a) and the positional relationship between the board accommodating recess 682 and the passive component 676a2 in Figure 14(b), the shortest distance y5 from the board accommodating recess 682 to the passive component 676a2 shown in Figure 14(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 14(a) (y5>y3).

[0321] 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.

[0322] In addition, other components such as passive component 676a1 (first passive component), ICs, resistor arrays, etc. 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. In this case, it is preferable that the "other components" are larger than the second passive component.

[0323] Furthermore, when passive component 676a3 in FIG. 14(a) and passive component 676a1 in FIG. 14(b) are placed on the side of substrate accommodating recess 682 (the side of the edge that does not have burrs 632 at break), they may be placed closer to substrate accommodating recess 682 than passive components (passive components 676a1 and 676a2 in FIG. 14(a)) placed on the side of the edge that has burrs 632 at break. Since they are placed in a position that is less susceptible to the stress at break, there is no need to consider clearance, and this increases the degree of freedom in substrate design.

[0324] In addition, such a board housing recess may be provided for a plurality of boards in one game machine. In this case, when a passive component A (passive component 616a1) is arranged at a distance m1 (distance x3) from the board housing recess in a certain board (for example, FIG. 10(b)), and a passive component B (passive component 676a2) is arranged at a distance m2 (y5) longer than the distance m1 from the board housing recess in another board (FIG. 14(b)), the passive component A is arranged so that the longitudinal direction of the passive component A coincides with the longitudinal direction of the board housing recess, and the passive component B may be arranged so that the longitudinal direction of the passive component B is perpendicular to the longitudinal direction of the board housing recess because the distance m2 longer than the distance m1 is secured, and the degree of freedom in board design can be secured by not uniformly limiting the arrangement direction of the passive components when designing the board. In addition, if the other board has fewer components mounted thereon than the certain board and the area of ​​the board mounting surface can be sufficiently secured, the passive components may be disposed 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 the freedom of board design can be secured by not uniformly limiting the orientation of the passive components when designing the board. Also, by making the distance from the board accommodating recess to the passive components and the orientation different depending on the board, it is easy to identify which board it is.

[0325] <Main control board for modification 1 / Summary> As described above, the gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine equipped with a first board (e.g., the main control board 670 shown in FIG. 14), the first board is a board having a recess of a first shape (e.g., the board accommodating recess 682 shown in FIG. 14), the first board is a board in which a manufacturer of the gaming machine can be identified by cutting a break portion (e.g., the break portion 696 shown in FIG. 14(a)), the break portion of the first shape is a portion where the break portion is formed, and the break portion of the first shape is formed along a long side of the first board.

[0326] According to the gaming machine of this embodiment, a first shaped recess is formed on the long side of the substrate (first substrate), so that when the fracture portion is cut, the distortion caused by the stress applied to the substrate can be reduced, and damage to the substrate and the components mounted on the substrate can be prevented. In this way, a gaming machine in which defects caused by component damage are suppressed can be provided.

[0327] Furthermore, if 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 its long side, which can leave traces of fraudulent activity, thereby improving crime prevention.

[0328] In the manufacturing process of game machines, the circuit board products are covered with various circuit board cases and are installed, fixed, and attached inside the game machine. However, many circuit board products have similar external shapes, and installation mistakes can occur during the manufacturing and assembly of game machines, or, even if they do not result in installation mistakes, it can be difficult to know which circuit board to install, resulting in wasted work time. However, the game machine of this embodiment makes it easy to distinguish between circuit boards, simplifying the process of manufacturing and assembling the game machine.

[0329] 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. 10 and passive components 676 such as resistors, capacitors, and coils shown in FIG. 14(a)), one of the plurality of components is a first component (e.g., passive component 606a1 shown in FIG. 10(b) and passive component 676a1 shown in FIG. 14(a)) arranged in the vicinity of 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.

[0330] With this configuration, the effect of the stress applied in the longitudinal direction of the recess of the first shape when the breaking portion is cut 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 in which defects due to damage to components are suppressed can be provided.

[0331] The first substrate is a substrate having a side different from the long side, 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. 10 and passive components 676 such as resistors, capacitors, and coils shown in FIG. 14(a)), one of the plurality of components is a first component (for example, passive component 606a1 shown in FIG. 10(b) and passive component 676a1 shown in FIG. 14(a)) disposed in the vicinity of the recess having the first shape, and one of the plurality of components is a first component (for example, passive component 606a1 shown in FIG. 10(b) and passive component 676a1 shown in FIG. 14(a)). The component is a second component (e.g., passive component 606a2 shown in FIG. 10(b) or passive component 676a2 shown in FIG. 14(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. 10(b) or shortest distance y3 shown in FIG. 14(a)) may be longer (x3>x4, y3>y4) than the shortest distance from the certain side to the second component (e.g., shortest distance x4 shown in FIG. 10(b) or shortest distance y4 shown in FIG. 14(a)).

[0332] With this configuration, a clearance (work space) can be secured from the recess of the first shape to the first passive component, which makes it easier to cut the breakage portion formed in the recess of the first shape, and improves workability. In addition, even if the cutting work is performed by placing fingers around the periphery of the recess of the first shape or by using a tool, the fingers or the tool can be prevented from touching the first passive component, and damage to the first passive component can be prevented in advance. In this way, a gaming machine in which malfunctions due to damage to parts are suppressed can be provided.

[0333] 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. 10(b) or the shortest distances β and γ shown in FIG. 14(a)) may be longer (x3'>x3, β>y3, γ>y3) than the shortest distance from the first shaped recess to the first component (e.g., the shortest distance x3 shown in FIG. 10(b) or the shortest distance y3 shown in FIG. 14(a)). 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.

[0334] 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 malfunctions due to damage to components are suppressed.

[0335] The container may also include a container (e.g., substrate container 642 shown in FIG. 13(b)) capable of storing the first substrate, and when the first substrate is stored in the container, a component (e.g., IC 606c shown in FIG. 13(b)) arranged on the first substrate may be visible through a recess of the first shape (e.g., substrate accommodating recess 612 shown in FIG. 13(b)).

[0336] With this configuration, the board can be easily viewed, making it easier to detect unauthorized components when they are installed, and the components mounted on the board can be confirmed while they are contained in the container, improving maintainability and workability.

[0337] Furthermore, the first substrate may be a substrate having a resist layer (e.g., resist layer 604 shown in FIG. 10), the first substrate may be a substrate having identification information (e.g., identification information 608 shown in FIG. 10) displayed in a predetermined area, the identification information being identification information including information capable of identifying one of the manufacturers of the gaming machine, and the predetermined area may be an area in which the resist layer is not formed.

[0338] 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.

[0339] The predetermined area may be an area where no pattern wiring is formed.

[0340] With this configuration, even if other information is printed, the visibility of the identification information can be improved, and convenience can be improved.

[0341] <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. 15(a). Fig. 15(a) is a plan view of main control board 690 according to Modification 2.

[0342] In the main control board 600 described using Figure 10, an example is shown in which the manufacturer of the gaming machine can be identified by separating the identification board 610 and leaving only the identification information 618 (name of the manufacturer of the slot machine 100: BBB Company, identification number of the main control board: XXX-YYY) on the main control board 600.

[0343] However, the "first board" of the present invention is not limited to this, and may be configured, for example, like main control board 690 of this modified example 2, so that the manufacturer of the gaming machine can be identified by a method such as striking out identification information 694 of main control board 690 (name of slot machine manufacturer: BBB Company, identification number of main control board: XXX-YYY) by laser engraving or the like, without separating identification board 692.

[0344] <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. 15(b). Fig. 15(b) is a plan view of main control board 696 according to Modification 3.

[0345] In the main control board 600 described with reference to FIG. 10, 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.

[0346] However, the "first board" of the present invention is not limited to this, and for example, like main control board 696 in this modified example 3, a plurality of identification boards 698 that can be detached from main control board 696 may be provided, first identification information (name of slot machine manufacturer: AAA Company, main control board identification number: XXX-YYY) printed on one identification board 698 and second identification information (name of slot machine manufacturer: BBB Company, main control board identification number: XXX-YYY) printed on the other identification board 698, and one of them may be configured to be detached.

[0347] <Pattern Arrangement> Next, the arrangement of symbols on each of the reels 110 to 112 will be described with reference to Figure 25. Figure 25 is a plan view of the arrangement of symbols on each of the reels (left reel 110, center reel 111, right reel 112).

[0348] On each of the reels 110 to 112, a predetermined number of symbols (20 symbols numbered 0 to 19 in this embodiment) of symbols of multiple 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 number 0 symbol of the left reel 110, a "bell symbol" is arranged on the number 1 symbol of the center reel 111, and a "replay symbol" is arranged on the number 0 symbol of the right reel 112.

[0349] <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.

[0350] <Measures to prevent circuit board fire spread / circuit board> Fig. 16(a) is a plan view of the substrate 700 according to this example seen from the power supply layer 710 side, and Fig. 16(b) is a partial cross-sectional view of the substrate 700 taken along line XX in Fig. 16(a). For ease of explanation, Fig. 16(b) shows the thicknesses of the conductor layer, insulating layer, and base material in the substrate 700 in an exaggerated manner.

[0351] The slot machine according to this embodiment includes a board 700 (certain board) shown in Fig. 16(a). As shown in Figs. 16(a) and 16(b), the board 700 includes a base material (core) 702, a GND layer (second conductor layer) 706 laminated on the base material 702, a power layer (first conductor layer) 710 laminated on the GND layer 706 via an insulating layer 708, a solder resist 713 applied on the power 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 layer 710.

[0352] 16(b) shows an example of a double-sided mounting board in which a conductor layer and an insulating layer are mounted on both sides of the base material (core) 702, but the present invention is not limited to this, and may be a single-sided mounting board in which a conductor layer and an insulating layer are mounted on only one side of the base material (core) 702. In the following, for convenience of explanation, only the structure on one side of the board 700 will be explained, and illustrations of solder resist 713, silk 715, etc. will be omitted in the drawings.

[0353] 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.

[0354] The "certain substrate" according to the present invention may be a 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 interchanged, 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 a power supply layer (first conductor layer) 710 is configured on the substrate side (lower side) with the insulating layer 708 sandwiched therebetween, 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. The "certain substrate" according to the present invention may also be a double-sided mounting substrate having a conductor layer and an insulating layer sandwiched between the substrate 702.

[0355] Furthermore, the uses of the "certain board" of the present invention are not particularly limited, and for example, the "certain board" of the present invention may be the main control board 600 described using FIG. 10, the sub-control board 650 described using FIG. 11, a power supply board that controls the power supply, a dispensing control board that controls dispensing, etc.

[0356] <Fire prevention measures for circuit boards / components> Next, the components 712 mounted on the board 700 will be described.

[0357] As shown in FIG. 16(a), a plurality of components 712 are mounted (placed) on a power supply layer 710 of a substrate 700.

[0358] In this example, the components 712 are mounted only on the power supply layer 710, and the GND layer 706 is a GND plane layer (a GND layer with no components mounted), but the "certain board" according to the present invention may be a board with multiple components arranged on at least one side, and may be, for example, a board with components mounted only on the GND layer 706, and the power supply layer 710 may be a power plane layer (a power supply layer with no components mounted), or may be mounted on both the power supply layer 710 and the GND layer 706. In addition, in the case of a board having three or more conductor layers, it is sufficient that the board has multiple components arranged on at least one layer.

[0359] 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. 17(a)) that drives the LEDs, and a motor driver IC 716 (described later using FIG. 17(b)) that drives a motor (not shown), as well as passive components 718 such as resistors, capacitors, coils, and mechanical components such as a connector 720.

[0360] The "active components" according to the present invention are not limited to light-emitting devices and driver ICs, but may be, for example, diodes, transistors, light-receiving devices such as photodiodes, various sensors such as magnetic sensors, and the like.

[0361] <Board fire prevention measures / components / LED drivers> FIG. 17(a) is a terminal layout diagram of the LED driver IC 714.

[0362] The LED driver IC714 is configured to have address input terminals A0 to A5 arranged at terminals Nos. 1 to 6, ground terminals 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.

[0363] A power supply terminal VCC (terminal number 38) of the LED driver IC 714 is soldered to a power supply wiring pattern 711 (described later using Figure 19, 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.

[0364] The ground terminals GND (terminal numbers 7, 20, 33) are soldered to the GND wiring pattern 706a (described later using Figure 19, 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.

[0365] 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.

[0366] <Board fire prevention measures / components / motor drivers> FIG. 17(b) is a terminal layout diagram of the motor driver IC 716.

[0367] 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.

[0368] Power terminals VMA (terminal numbers 2 and 3) and VMB (terminal numbers 16 and 17) of the motor driver IC 716 are soldered to a power wiring pattern 711 of a power layer 710 of the substrate 700 and are electrically connected to the power wiring pattern 711 of the power layer 710.

[0369] The ground terminal GND (terminal number 20) is soldered to the GND wiring pattern 706 a of the GND layer 706 through a via formed in the insulating layer 708 , and is electrically connected to the GND wiring pattern 706 a of the GND layer 706 .

[0370] The bridge A output 1 terminal AOUT1 (terminal numbers 4, 5), the bridge A ground output terminal ISENA (terminal numbers 6, 7), the bridge A output 2 terminal AOUT2 (terminal numbers 8, 9), the bridge B output 2 terminal BOUT2 (terminal numbers 10, 11), the bridge B ground output terminal ISENB (terminal numbers 12, 13), and the bridge B output 1 terminal BOUT1 (terminal numbers 14, 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.

[0371] <Board fire prevention measures / power layer> Next, the power supply layer 710 of the substrate 700 will be described.

[0372] FIG. 18(a) is a pattern diagram showing an example of a power wiring pattern of a power supply layer 710 of a substrate 700, and FIG. 19(a) is a partially enlarged view of the power supply layer 710, showing an enlarged portion indicated by the symbol A in FIG. 18(a).

[0373] As shown enlarged in FIG. 19(a), a 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).

[0374] The power supply wiring pattern 711a includes a first power supply line 711a1, and two power supply lines, a second power supply line 711a2 and a third power supply line 711a3, which branch off from one end of the first power supply line 711a1 as a base end.

[0375] A power supply wiring pattern 711b is formed adjacent to and below a 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 710a1 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.

[0376] The power supply wiring pattern 711b is connected to a power supply of a predetermined voltage (in this example, DC24v). 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, DC24v) as the power supply wiring pattern 711b.

[0377] 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 710a2 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.

[0378] 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.

[0379] In FIG. 19(a), the power supply wiring pattern 711d arranged on the left side, the power supply wiring pattern 711e arranged in the center, and the power supply wiring patterns 711f and 711g arranged 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.

[0380] In addition, the "first wiring pattern" according to the present invention is not limited to a power 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. Also, it goes without saying that the voltage value of the power supply supplied to the "power wiring pattern" according to the present invention is not limited to this example.

[0381] <Board fire prevention measures / GND layer> Next, the GND layer 706 of the substrate 700 will be described.

[0382] FIG. 18(b) is a pattern diagram showing a GND wiring pattern 706a of a GND layer 706 of a substrate 700, and FIG. 19(b) is a partially enlarged view of the GND layer 706, showing an enlarged portion indicated by the symbol B in FIG. 18(b).

[0383] As shown in Figures 16(b) and 19(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 cut-out (solid cut-out) 706b where this GND wiring pattern 706a is not formed (cut-out).

[0384] Since the GND wiring pattern 706a of the board 700 according to this example is configured as a solid ground (solid wiring pattern), the noise resistance (current capacity) of the board 700 can be ensured.

[0385] It should be noted that the "second wiring pattern" according to the present invention is not limited to a GND wiring pattern. 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.

[0386] <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.

[0387] FIG. 19C is a pattern diagram showing the power supply layer 710 shown in FIG. 19A and the GND layer 706 shown in FIG. 19B superimposed on each other.

[0388] Non-overlapping of substrate 700 region As shown in FIG. 16(b), NOE is a region 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. In this example, the region is composed of a first non-overlapping region NOE1 in which the power supply wiring pattern 711 is formed and the GND wiring pattern 706a is not formed (composed of a pattern hole 706b), and a second non-overlapping region NOE2 in which neither the power supply wiring pattern 711 nor the GND wiring pattern 706a is formed.

[0389] 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 neither the power supply wiring pattern 711 nor the GND wiring pattern 706a is formed.

[0390] On the other hand, the overlapping region OE is a region 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. 16(b).

[0391] 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 supply 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.

[0392] <Measures to prevent fire from spreading on circuit boards / relationship between non-overlapping areas and component positions> Next, the positional relationship between the non-overlapping area NOE of the substrate 700 and the components mounted on the power supply layer 710 (the LED driver IC 714 and the motor driver 716) will be described with reference to FIG.

[0393] Fig. 20(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 the motor driver 716 mounted on the power supply layer 710. In Fig. 20(a), the LED driver IC 714 and the motor driver 716 are mounted upside down from the orientation shown in Figs. 17(a) and (b).

[0394] As explained using Figure 17 (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.

[0395] FIG. 20(b) is a cross-sectional view taken along line YY of the LED driver 714 shown in enlarged view in FIG. 20(a).

[0396] As shown in FIG. 20(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 therein, but is composed of a pattern hole 706b.

[0397] That is, the area in which the power supply terminal VCC (terminal number 38) of the LED driver 714 is implemented is a non-overlapping area NOE 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 (in this example, an area in which 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).

[0398] 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 with an insulating layer in between 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, a highly safe gaming machine can be provided.

[0399] 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.

[0400] 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.

[0401] 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 in 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 in 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) 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.

[0402] As explained using Figure 17 (b), the power supply terminal VMA (terminal numbers 2 and 3) and the power supply terminal VMB (terminal numbers 16 and 17) of the motor driver IC 716 are soldered to the power supply wiring pattern 711 of the power supply layer 710 of the substrate 700 and are electrically connected to the power supply wiring pattern 711 of the power supply layer 710.

[0403] FIG. 20C is a cross-sectional view taken along line ZZ of the motor driver 716 shown in an enlarged scale in FIG.

[0404] As shown in FIG. 20(c), the GND layer 706 below the power supply wiring pattern 710 to which the power supply terminal VMA (terminal number 2) of the motor driver 716 is connected does not have a GND wiring pattern 706a formed thereon, and is composed of a pattern hole 706b.

[0405] That is, the area in which the power supply terminal VMA (terminal number 2) of the motor driver 716 is implemented is a non-overlapping area NOE 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 (in this example, an area in which 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).

[0406] 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 with an insulating layer in between 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, a highly safe gaming machine can be provided.

[0407] Although not shown in the figure, the GND layer 706 below the power supply wiring pattern 711 to which the power supply terminal VMA (terminal number 3) and the power supply 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 composed of a pattern hole 706b.

[0408] 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-free layer in which the power supply wiring pattern 711 is not formed.

[0409] As described with reference to FIG. 17(b), the bridge A output 1 terminal AOUT1 (terminal numbers 4, 5), the bridge A ground output terminal ISENA (terminal numbers 6, 7), the bridge A output 2 terminal AOUT2 (terminal numbers 8, 9), the bridge B output 2 terminal BOUT2 (terminal numbers 10, 11), the bridge B ground output terminal ISENB (terminal numbers 12, 13), and the bridge B output 1 terminal BOUT1 (terminal numbers 14, 15) of the motor driver IC716 are all output terminals that are electrically connected to a motor (not shown) and drive the motor.

[0410] 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 therein, but is composed of pattern holes 706b.

[0411] In other words, 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.

[0412] Also, it may be a region 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 a region 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.

[0413] On the other hand, the GND layer 706 below the conductor layer to which terminals other than the power terminal, GND terminal, and output terminals 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.

[0414] 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.

[0415] Also, in this example, as shown in FIG. 20(a), multiple (in this example, six) LED drivers 714 and multiple (in this example, two) 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 of the LED drivers 714 and motor drivers 716 are also formed at a distance on the substrate 700.

[0416] Although the noise resistance of the board can be improved by forming the power supply wiring pattern and the GND wiring pattern with a solid wiring pattern, since the solid wiring pattern is removed in the non-overlapping area, a certain degree of reduction in noise resistance is unavoidable. However, since the noise resistance is significantly reduced when the areas where the solid wiring pattern is removed are provided continuously, it is possible to prevent a significant reduction in noise resistance caused by forming the power supply wiring pattern and the GND wiring pattern with a solid wiring pattern by forming the non-overlapping area at a distance.

[0417] In addition, the area of ​​pattern cutout 706b as the non-overlapping area increases as the number of output terminals and power supply terminals of the driver increases. In other words, the non-overlapping area near the first driver (first active component) which has many terminals (specific terminals) that may generate heat or cause a fire is larger than the non-overlapping area near the second driver (second active component) which has fewer terminals (specific terminals) that may generate heat or cause a fire than the first driver.

[0418] 18(a) and 20 indicate via holes x1, x2, and x3, and no GND wiring pattern is laid in these portions (in the embodiment, vias and through holes are collectively referred to as "via holes"). The via holes x1 and x2 are via holes provided in the vicinity of the output terminals and power supply terminals of the LED driver 714 and the motor driver 716, and the via hole x1 is disposed on an extension of the wiring pattern connected to the motor driver 716, and the via hole x2 is disposed on an extension of the wiring pattern connected to the LED driver 714 and the pattern hole 706b adjacent thereto. The non-laying portions of the GND wiring pattern corresponding to the via holes x1 and x2 are formed continuously with the pattern hole 706b formed as a fire spread prevention measure. In this way, by continuously forming the non-installed parts of the GND wiring pattern corresponding to the via holes x1 and x2 located near the driver and the pattern cut-outs as a fire spread prevention measure, it is possible to provide a more effective fire spread prevention measure even if the carbonized conductive path becomes larger than if the non-installed parts were not continuously formed, and in the unlikely event that a fire spreads to the board, it can be limited to a localized state.

[0419] On the other hand, in the via hole x3 located away from the LED driver 714 and the motor driver 716, it is not continuous with the pattern cutout 706b, is not arranged on an extension line of the wiring pattern connected to the LED driver 714 or the motor driver 716, and is not arranged on an extension line of a wiring pattern adjacent to the wiring pattern connected to the LED driver 714 or the motor driver 716.

[0420] <Measures to prevent fire from spreading on circuit boards / Conventional problems and the concept of the present invention> Next, the problems with the conventional technology and the concept of the present invention will be described.

[0421] Fig. 21(a) is a conceptual diagram showing the problems with the circuit board of a conventional game machine. In Fig. 21 and Fig. 22, in order to simplify the explanation, only the power layer, the insulating layer, and the GND layer in the circuit board are shown.

[0422] Gaming machines, such as slot machines, are equipped with various circuit boards. These circuit 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.

[0423] Specifically, while passive components become hot themselves, the hottest part of active components is near the output terminal. As shown in Figure 21(a-2), if the area near the terminal of an IC (component) becomes hot, there is a risk of a short circuit (spark). In this case, the insulating layer of the board may be gouged (destroyed) by the sparks that are generated.

[0424] As shown in Figure 21(a-3), when the insulating layer of the board 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 may cause a short circuit between the upper and lower wiring patterns that were insulated by the insulating layer (in this example, the upper power layer and the lower GND layer), which may lead to a fire.

[0425] FIG. 21(b) is a diagram showing a schematic diagram of the substrate of the present invention.

[0426] 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 21 (b-1).

[0427] 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 a spark occurs, as shown in Figure 21 (b-2), and the insulating layer 708 of the substrate is destroyed by the spark 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 cut-out 706b is provided), 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. By preventing the gaming machine from catching fire, a highly safe gaming machine can be provided.

[0428] In this example, the non-overlapping area NOE is an example of an area in which a power supply wiring pattern of the power supply layer is formed and a GND wiring pattern of the GND layer is not formed. However, the area may be an area in which a GND wiring pattern of the GND layer is formed and a power supply wiring pattern of the power supply layer is not formed, or an area including an area in which both the power supply wiring pattern of the power supply layer and the GND wiring pattern of the GND layer are not formed.

[0429] <Board fire spread prevention / non-overlapping area (Example 1)> FIG. 22(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. 22(b) is a cross-sectional view taken along line AA in FIG. 22(a).

[0430] 22(a) and 22(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. 22(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.

[0431] Figure 22(c) is a plan view showing an example where 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 22(d) and (d') are cross-sectional views along line BB in Figure 22(c).

[0432] As shown in Figures 22(c) and (d), if the non-overlapping area NOE of the substrate 700 is large enough not to include the entire maximum envisaged area CE of the carbonized conductive path, then as shown in Figure 22(d'), the generated sparks will destroy the insulating layer 708 of the substrate 700, forming a carbonized conductive path of the maximum envisaged area CE. As a result, a short circuit will occur between the power supply layer 710 and the GND layer 706, which were insulated by the insulating layer 708, and this may induce a fire.

[0433] The assumed maximum area CE of the carbonized conductive path will differ depending on the structure and characteristics of the components mounted on the board. For example, even if a 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 become hot, then the assumed maximum area CE of the carbonized conductive path will be an area centered on this junction, but 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 become hot, then the assumed maximum area CE of the carbonized conductive path will be an area centered on this internal connection.

[0434] 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. In addition, when the terminals of the components are thick, the expected maximum area of ​​the carbonized conductive path becomes larger accordingly, so the range of the non-overlapping region must also be made larger.

[0435] <Board fire prevention measures / non-overlapping areas (other examples)> FIG. 23(a) is a plan view showing the non-overlapping area NOE2 according to the second embodiment.

[0436] This embodiment is an example in which a non-overlapping area NOE2 (in this example, a rectangular area with a height H2 and a width W2) is formed so as to include the entire component 712 (in this example, a DIP-type IC) mounted on the power layer 710. Note that in the figure, the power terminal is arranged on one side of the IC in the short-side direction, toward the lower side, but in the example shown in Fig. 23(a), it is preferable for the power terminals to be arranged on both sides in the short-side direction and distributed above and below.

[0437] The non-overlapping area NOE2 of the substrate 700 may be an area large enough to include at least the expected maximum area CE of a carbonized conductive path expected on the substrate 700. However, since there is a risk of a carbonized conductive path being formed in the vicinity of the component 712 or the power wiring pattern 711, if the average width of the power wiring pattern 711 of the power layer 710 is w1, the maximum width is w2, and the maximum horizontal length of the power wiring pattern 711 is w3, then it is preferable that the width W2 of the non-overlapping area NOE2 is longer than any of these, and that the relationship is "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."

[0438] Also, for the same reason, if the maximum vertical length of the power supply wiring pattern 711 is h1, then 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".

[0439] According to this example, the non-overlapping area NOE2 is an area that is large enough to include at least the assumed maximum area CE of the carbonized conductive path, and in the thickness direction of the substrate, 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 do not overlap. 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 the gaming machine from catching fire, a highly safe gaming machine can be provided.

[0440] 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 an insulating layer (in this example, the upper power layer and the lower GND layer), and by preventing the gaming machine from catching fire, it is possible to provide a highly safe gaming machine.

[0441] FIG. 23(b) is a plan view showing the non-overlapping area NOE3 according to the third embodiment.

[0442] This embodiment is an example in which 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 on one side in the short direction of the IC, but in the example shown in Fig. 23(b), it is preferable for the power terminals to be arranged on one side in the short direction.

[0443] According to this example, the non-overlapping area NOE3 is an area large enough to include at least the assumed maximum area CE of the carbonized conductive path, and in the thickness direction of the substrate, 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 do not overlap. 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 the gaming machine from catching fire, a highly safe gaming machine can be provided.

[0444] 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.

[0445] 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.

[0446] FIG. 23(c) is a plan view showing the non-overlapping area NOE4 according to the fourth embodiment.

[0447] This embodiment is an example in which a non-overlapping area NOE4 (in this embodiment, a rectangular area with a height H4 and a width W4) is formed so as to include a plurality of terminals on one side in the longitudinal direction of a component 712 (in this embodiment, a DIP-type IC) mounted on the power layer 710. Note that in the figure, the power terminals are arranged on one side in the short direction of the IC, but in the example shown in Fig. 23(c), it is preferable that the power terminals are arranged on one side in the longitudinal direction.

[0448] According to this example, the non-overlapping area NOE4 is an area large enough to include at least the assumed maximum area CE of the carbonized conductive path, and in the thickness direction of the substrate, 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 do not overlap. 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 the gaming machine from catching fire, a highly safe gaming machine can be provided.

[0449] In addition, since the non-overlapping region NOE4 is an area of a size including the power supply wiring pattern 711, even if a carbonized conductive path is formed in the vicinity of the power supply wiring pattern 711, 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 can be prevented from short-circuiting, and by preventing ignition from the game table, a highly safe game table can be provided.

[0450] 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, and 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.

[0451] FIG. 24(a) is a plan view showing the non-overlapping region NOE5 according to Example 5, and FIG. 24(b) is a plan view showing an example in which the wiring pattern of the power supply wiring line in FIG. 24(a) is changed.

[0452] 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.

[0453] In the examples shown in FIGS. 24(a) and 24(b), the common point is 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. 24(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. 24(b) (in this example, a rectangular region having a height H5 and a width W5' (W5' < W5)) is smaller in area than the non-overlapping region NOE5 shown in FIG. 24(a) (in this example, a rectangular region having a height H5 and a width W5).

[0454] According to the example shown in FIG. 24(b), a first power supply wiring pattern 711x and a second power supply wiring pattern 711y which supply power from different power sources to a component 712 are arranged close to each other, so that the size of the non-overlapping area NOE5' can be made smaller than the non-overlapping area NOE5 shown in FIG. 24(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.

[0455] <Summary of measures to prevent circuit board fire spread> As described above, the gaming machine according to the present 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 includes a certain board (for example, the board 700 shown in FIG. 16(a)), and the certain board is a board having at least a plurality of conductor layers, an insulating layer (for example, the insulating layer 708 shown in FIG. 16(b)), and a base material (for example, the base material 702 shown in FIG. 16(b)). The certain board is a board 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. 19(a)). the certain substrate is a substrate layer (e.g., a power supply layer 710 shown in FIG. 16(b)), one of the plurality of conductor layers is a second conductor layer (e.g., a GND layer 706 shown in FIG. 16(b)) having a second wiring pattern (e.g., a GND wiring pattern 706a shown in FIG. 19(b)); the certain substrate is a substrate in which the first conductor layer is configured on the one side with the insulating layer sandwiched therebetween, the certain substrate is a substrate in which the second conductor layer is configured 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., a non-overlapping region NOE shown in FIG. 16(b)) in which the first wiring pattern and the second wiring pattern do not overlap in the thickness direction of the certain substrate.

[0456] According to the gaming machine of this embodiment, by providing a non-overlapping region where 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, scratches such as cracks, etc.), the resistance at the damaged area increases, which may promote heat generation and carbonization and cause a short circuit, and even if such a situation occurs, the wiring patterns are not overlapped, so that the damage can be prevented from spreading. In addition, it is possible to prevent a situation in which a part of the insulating layer of the board becomes a carbonized conductive path due to a fire from the terminals of the components, causing a short circuit between the upper and lower wiring patterns insulated by the insulating layer, and by preventing a fire from the gaming machine, a highly safe gaming machine can be provided.

[0457] 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. 20(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. 20(a), one lateral side of the motor driver 716 shown in FIG. 20(a), an area including the entire component 712 shown in FIG. 23(a), one lateral side of the component 712 shown in FIG. 23(b), or one longitudinal side of the component 712 shown in FIG. 23(c).

[0458] With this configuration, even if a certain component shorts out, by making the area around the certain component a non-overlapping area, it is possible to prevent a situation in which a short circuit occurs between the wiring patterns on the upper and lower layers that are insulated by the insulating layer.

[0459] Furthermore, the certain component may be a specific active component (for example, an LED driver 714 shown in FIG. 20(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).

[0460] 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 board and turn part of the board's insulating layer into a carbonized conductive path. However, by making the area near the active components a non-overlapping area, it is possible to prevent a short circuit from occurring between the wiring patterns on the upper and lower layers that were previously insulated by the insulating layer.

[0461] In addition, the region of the certain substrate in which 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 region in which the first wiring pattern and the second wiring pattern overlap in the thickness direction of the certain substrate.

[0462] With this configuration, it becomes possible to form the power supply wiring pattern and the GND wiring pattern in the overlapping region as solid wiring patterns, thereby improving the noise resistance of the board.

[0463] Furthermore, the non-overlapping region (e.g., the non-overlapping region NOE shown in FIG. 16(b)) may be a region in which either the first wiring pattern or the second wiring pattern (e.g., the power supply wiring pattern 711 shown in FIG. 16(b)) is formed, and the other of the first wiring pattern or the second wiring pattern (e.g., the GND wiring pattern 706a shown in FIG. 16(b)) is not formed.

[0464] With this configuration, the first wiring pattern and the second wiring pattern can be physically separated, thereby making it possible to prevent a situation in which a short circuit occurs between the upper and lower wiring patterns that are insulated by an insulating layer.

[0465] 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. 16(b)), and the second wiring pattern may be the other of the power supply wiring pattern or the GND wiring pattern (for example, the GND wiring pattern 706a shown in FIG. 16(b)).

[0466] With this configuration, the power supply wiring pattern and the GND wiring pattern can be physically separated, making it possible to prevent a situation in which a short circuit occurs between the power supply wiring pattern and the GND wiring pattern that are insulated by an insulating layer.

[0467] In addition, the first wiring pattern may be either a signal wiring pattern (e.g., a signal line to which an output terminal of a motor driver IC 716 is connected, as shown in FIG. 17(b) or FIG. 20(c)) or a GND wiring pattern (e.g., the GND wiring pattern 706a shown in FIG. 16(b)), and the second wiring pattern may be the other of the signal wiring pattern and the GND wiring pattern.

[0468] With this configuration, the signal wiring pattern and the GND wiring pattern can be physically separated, making it possible to prevent a short circuit from occurring between the signal wiring pattern and the GND wiring pattern that are insulated by the insulating layer.

[0469] In addition, the first wiring pattern may be either a signal wiring pattern (for example, a signal line to which an output terminal of a motor driver IC 716 is connected, as shown in FIG. 17(b) or FIG. 20(c)) or a power supply wiring pattern (for example, a power supply wiring pattern 711 shown in FIG. 16(b)), and the second wiring pattern may be the other of the signal wiring pattern or the power supply wiring pattern.

[0470] With this configuration, the signal wiring pattern and the power supply wiring pattern can be physically separated, making it 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 an insulating layer.

[0471] 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 FIG. 19(b) and FIG. 20(a) to (c)) is configured as a solid wiring pattern, the certain substrate is a substrate in which a plurality of the specific active components (for example, the LED driver 714 and the motor driver 716 shown in FIG. 17 and FIG. 20(a)) are arranged (for example, in FIG. 20, a plurality of LED drivers 714 (same type of ICs) are arranged at a distance from each other, a plurality of motor drivers 716 (same type of ICs) are arranged at a distance from each other, or the LED driver 714 and the motor driver 716 (different types of ICs) are arranged at a distance), the certain substrate is a substrate in which the non-overlapping regions are formed corresponding to each of the specific active components, and the certain substrate may be a substrate in which the respective non-overlapping regions are formed at a distance from each other.

[0472] Although the noise resistance of the board can be improved by forming the power supply wiring pattern and the GND wiring pattern with a solid wiring pattern, since the solid wiring pattern is removed in the non-overlapping area, a certain degree of reduction in noise resistance is unavoidable. However, since the noise resistance is significantly reduced when the areas where the solid wiring pattern is removed are provided continuously, it is possible to prevent a significant reduction in noise resistance caused by forming the power supply wiring pattern and the GND wiring pattern with a solid wiring pattern by forming the non-overlapping area at a distance.

[0473] <<Embodiment 2>> Next, a gaming machine (slot machine) according to a second embodiment of the present invention will be described with reference to FIGS.

[0474] In addition, in describing the gaming machine of embodiment 2, only the configurations that are different from the gaming machine of embodiment 1 above will be described, and in the event that symbols are duplicated in the specification and drawings, the symbols in embodiment 2 will take precedence.

[0475] <Main control board> First, the main control board 600 will be described.

[0476] Fig. 25 is a plan view of main control board 600 before components are mounted, and Fig. 26 is a plan view with the reference numerals removed from Fig. 25. Fig. 27 is a plan view of main control board 600 after components are mounted, and Fig. 28 is a plan view with the reference numerals removed from Fig. 27.

[0477] The main control board 600 is composed of a substrate 602 consisting of a rectangular plate-like body, a wiring pattern 604 formed on at least one side of the substrate 602, multiple types of position indications 700 (position indications 710, 712, etc. shown in Figure 25; details will be described later) printed on at least one side of the substrate 602, and multiple types of components 608 (IC1, resistor R1, etc. shown in Figure 27; details will be described later) mounted on at least one side of the substrate 602.

[0478] In addition, the "board" according to the present invention is not limited to the main control board 600 constituting the main control unit 300, but may be, for example, a board constituting the first sub-control unit 400 or the second control unit 500 described using Figure 9, or it may be a power supply board or a performance control board, etc., and the type of board is not particularly limited.

[0479] Furthermore, the "wiring pattern," "position indication," and "component" according to the present invention are not limited to being disposed on one surface (e.g., the front surface) of the substrate 602, but may be disposed on the other surface (e.g., the back surface) of the substrate 602, or may be disposed on both one surface (e.g., the front surface) and the other surface (e.g., the back surface). In the case of a multi-layer substrate, they may be disposed on one surface and / or the other surface of each layer.

[0480] <Main control board / wiring pattern> Next, the wiring pattern 604 of the main control board 600 will be described.

[0481] The wiring pattern 604 is composed of a power supply wiring pattern 604a electrically connected to the power supply terminal etc. of the component 608, a GND wiring pattern 604b electrically connected to the GND (ground) terminal etc. of the component 608, and a signal wiring pattern 604c electrically connected to the input / output terminal etc. of the component 608.

[0482] For example, the power supply wiring pattern 604a shown in FIG. 29(b) is electrically connected to a power supply terminal IC8vp (e.g., a 5 V power supply terminal) of IC8, a power supply terminal C35vp (e.g., a 5 V power supply terminal) of capacitor C35, and a power supply device (not shown), and is a line that supplies power output from the power supply device to IC8, capacitor C35, etc.

[0483] In this example, the power supply wiring pattern 604a is formed on the back surface of the substrate 602 (the surface opposite to the mounting surface of IC8) in an approximately straight line from one side in the longitudinal direction of IC8 to the other side, passing under one side in the lateral direction of the IC8 package (the side on which the power supply terminal IC8vp of IC8 is located).

[0484] This power supply wiring pattern 604a is connected to the power supply terminal IC8vp of IC8 and the power supply terminal C35vp of capacitor C35 arranged on the surface of the substrate 602 (the mounting surface of IC8) via through holes (not shown) formed in the substrate 602.

[0485] In addition, the GND wiring pattern 604b shown in Figure 29 (b) is electrically connected to the GND terminal IC8gp of IC8, the GND terminal C35gp of capacitor C35, the GND terminals of other components 608, etc., and is a line that serves as the reference voltage (e.g., 0v) of the main control board 600.

[0486] In this example, the GND wiring pattern 604b is formed on the back surface of the substrate 602 (the surface opposite the mounting surface of IC8) in approximately a straight line from one side of the length of IC8 to the other side, passing underneath the other short-side side of the IC8 package (the side on which the GND terminal IC8gp of IC8 is located).

[0487] This GND wiring pattern 604b is connected to the GND terminal IC8gp of IC8 arranged on the surface (mounting surface of IC8) of the substrate 602 and the GND terminal C35gp of the capacitor C35 via through holes (not shown) formed in the substrate 602.

[0488] According to this example, even if the component (IC8) is installed incorrectly (inserted backwards), the capacitor is disposed between the power terminal and GND terminal of the component, so that damage to the component due to application of reverse voltage, etc. can be prevented in advance.

[0489] <Main control board / components> Next, the components 608 (IC1, resistor R1, etc.) of the main control board 600 will be described with reference to FIG.

[0539] The identification mark 730b is composed of the character string "CN" indicating that the type of the part is a connector, and the symbol "CNn" consisting of the number "n" indicating that the control number is n (n is a positive integer).

[0540] The No. 1 pin identification mark 730c is a triangular shape, and is arranged so that the apexes of the triangle indicate the positions of the No. 1 pins of the connectors CN1 to CN5.

[0541] <Main control board / connector CN6 to CN7 (test connector) position display> Position indication 731 is a position indication that shows the installation positions of connectors CN6 to CN7 (test connectors), and in this example is composed of contour graphic indication 731a that shows the contours of both ends of each of connectors CN6 to CN7, identification indication 731b that can identify the type of component and the control number, and pin 1 identification indication 731c that can identify the position of pin 1.

[0543] The No. 1 pin identification mark 731c is a triangular shape, and is arranged so that the apexes of the triangle indicate the positions of the No. 1 pins of the connectors CN6 to CN7.

[0544] <Main control board / test component position display> As described above, IC16 to IC19 (test logic ICs) and connectors CN6 to CN7 (test connectors) are test components 608 (test components).

[0549] <Main control board / 7SEG display position display> The position display 734 is a position display that indicates the installation position of the 7SEG display unit SEG, and in this example, is composed of a graphic display 734a that indicates the installation position of the 7SEG display unit SEG, and an identification display 734b that can identify the type of part and the management number.

[0550] The identification mark 734b is composed of the character string "SEG" indicating that the type of the part is a segment display, and the symbol "SEGn" consisting of the number "n" indicating that the control number is n (n is a positive integer).

[0551] <Main control board / positional relationship between parts and position display> Next, the positional relationship between the parts and the position indications will be described with reference to FIGS.

[0552] <Positional relationship between main control board / components and position display (Example 1)> FIG. 29(a) is a plan view for explaining the positional relationship between the component and the position indication (Example 1).

[0553] Near the cutout portion IC8a of IC8 (motor driver IC), capacitor C35 is arranged in a position that does not overlap with the direction identification figure 718a2 (a position that does not interfere with the visibility of the direction identification figure 718a2) and is approximately parallel to the short side direction of IC8 (the up and down direction in Figure 29).

[0554] According to this example, the capacitor C35 can be arranged as close as possible to the component (IC8) while ensuring the visibility of the identification mark (direction identification figure 718a2), ​​and the mounting surface of the board, which has limited space, can be effectively utilized. In addition, the presence of the identification mark ensures a minimum distance between the component and the capacitor C35, preventing the components from interfering with each other when mounting the components, and ensuring reliable mounting of the components.

[0555] The shortest distance from the opening of cutout IC8a of IC8 to capacitor C35 is longer than the shortest distance from cutout IC8a of IC8 to pin 1 identification mark 718c.

[0556] According to this example, even if there is no positional marking indicating pin 1 (pin 1 identification marking 718c), the installation orientation of the component can be recognized by the identification marking (cutout portion IC8a). Therefore, by deliberately locating the positional marking indicating pin 1 at a position farther away than the identification marking (cutout portion IC8a), it is possible to avoid a situation in which the positional marking indicating pin 1 is damaged when the component (IC8) or capacitor C35 is mounted, or the positional marking indicating pin 1 becomes difficult to see due to the component or capacitor.

[0557] As described above, the position display 718 of IC8 is composed of a graphic display 718a that imitates the appearance of IC8, an identification display 718b that can identify the type of component and the control number, and a pin 1 identification display 718c that can identify the position of pin 1.

[0558] The graphic display 718a is composed of a rectangular outline graphic 718a1 that represents the outline of the IC8, and a direction identification graphic 718a2 (identification display) that is a semicircular recess that imitates the appearance of the cutout portion IC8a (identification portion) of the IC8.

[0559] The orientation identifying graphic 718a2 is configured so that the maximum width W1 of the opening end thereof is greater than the maximum width W2 of the opening end of the notch IC8a of the IC8 (W1>W2).

[0560] According to this example, the mounting orientation of the component can be easily confirmed before the component is mounted, preventing component mounting errors (reverse insertion), and even after the component is mounted, the identification markings can be easily confirmed, so that it is possible to confirm at a glance that the mounting orientation of the component is correct, thereby increasing convenience.

[0561] When the IC8 is mounted on the base material 602, a part of the graphic display 718a is covered by the IC8, and as a result, a part of the contour graphic 718a1 and a part of the direction identification graphic 718a2, which are shown by dotted lines in Fig. 29(a), become invisible when viewed from the front. Hereinafter, the area of ​​the position display that becomes invisible due to the IC when the IC is mounted on the base material 602 may be referred to as the "invisible area."

[0562] According to this example, by making part of the position indication invisible due to the component, it becomes possible to print other position indications or mount other components near the component, thereby making effective use of the mounting surface of the board, which has limited space.

[0563] In addition, for the invisible area (in this example, part of the contour figure 718a1 and part of the direction identification figure 718a2), ​​silk printing consisting of lines other than solid lines (for example, dotted lines or dashed lines) may be printed, or silk printing may be omitted.

[0564] With this configuration, the area requiring silk screen printing can be made smaller, which may reduce the number of steps.

[0565] Meanwhile, other parts of contour graphic 718a1 (in this example, both longitudinal ends of contour graphic 718a1) are visible when viewed from the front, and therefore it is possible to identify position indication 718 of IC8 even if IC8 is mounted on substrate 602. Hereinafter, an area of ​​the position indication that is not obscured by the IC when the IC is mounted on substrate 602 (visible when viewed from the front when the IC is mounted on substrate 602) may be referred to as a "visible area".

[0566] According to this example, it is possible to easily check a portion of the contour figure 718a1 even after the component has been mounted, so that it is possible to check at a glance that the mounting orientation of the component is correct, thereby improving convenience.

[0567] Here, the length from the left end of IC8 in the visible area on one longitudinal side of contour figure 718a1 (in this example, the left longitudinal side) (hereinafter sometimes referred to as the "left visible area") is defined as L1, and the length from the right end of IC8 in the visible area on the other longitudinal side of contour figure 718a1 (in this example, the right longitudinal side) (hereinafter sometimes referred to as the "right visible area") is defined as L2. In this example, the length L1 from the left end of IC8 in the left visible area is longer than the length L2 from the right end of IC8 in the right visible area (L1>L2).

[0568] In addition, another portion of the orientation identification figure 718a2 (in this example, the open end of the orientation identification figure 718a2) is a visible area, so even if the IC8 is mounted on the substrate 602, it is possible to identify the installation orientation of the IC8.

[0569] According to this example, it is possible to easily check part of the identification marking (orientation identification figure 714a) even after the component has been mounted, so that it is possible to check at a glance that the mounting orientation of the component is correct, thereby improving convenience.

[0570] Identification mark 718b (in this example, the symbol "IC8") is printed near IC8, making it possible to identify that the type of component is an IC (integrated circuit) and that the control number is 8; however, because the model number of IC8 is printed only on the package of IC8, the model number of IC8 cannot be identified from identification mark 718b alone.

[0571] <Positional relationship between main control board / components and position display (Modification 1 of Example 1)> FIG. 29(b) is a plan view for explaining the positional relationship between the component and the position indication (Modification 1 of Example 1).

[0572] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 1, so that the length L1 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 is made the same as the length L1 from the right end of IC8 in the right visible area of ​​the contour figure 718a1.

[0573] According to this example, the width of the position indication that is exposed to the outside and visible is the same length in the longitudinal direction of the IC, so that the position indication can be used as a guide to accurately position the IC in the longitudinal direction, thereby improving convenience when mounting components.

[0574] <Positional relationship between main control board / components and position display (Modification 2 of Example 1)> FIG. 29(c) is a plan view for explaining the positional relationship between the component and the position indication (Modification 2 of Example 1).

[0575] In this example, the length of the right side in the longitudinal direction of the contour graphic 718a1 is made longer than in the first embodiment, so that the length L4 from the right end of the IC8 in the right visible region of the contour graphic 718a1 is made longer than the length L1 from the left end of the IC8 in the left visible region of the contour graphic 718a1 (L1 <L4)。

[0576] In this example, the width of the position indication that is exposed to the outside and visible is longer on one side of the IC in the longitudinal direction than on the other side, so that it is possible to place components near the IC on one side of the IC, while printing a large, conspicuous position indication on the other side of the IC, thereby increasing convenience when installing components.

[0577] <Positional relationship between main control board / components and position display (Modification 3 of Example 1)> FIG. 29(d) is a plan view for explaining the positional relationship between the component and the position indication (third modification of the first embodiment).

[0578] In this example, the length of the right longitudinal side of the contour figure 718a1 is made shorter than in Example 1, so that the contour figure 718a1 is not exposed to the outside from the left end of the IC8, and there is no visible area on the right side of the contour figure 718a1.

[0579] According to this example, the area of ​​the position marking exposed to the outside on one longitudinal side of the component (IC8) is reduced, making it possible to print other position markings or mount other components on that side of the component (IC8), thereby making effective use of the mounting surface of the board, which has limited space.

[0580] In this example, a cutout portion IC8a is formed near pin 1 of IC8, but the present invention is not limited to this example. For example, as shown in FIG. 29(d), instead of (or in addition to) cutout portion IC8a, a circular recess IC8b (identification portion) that can identify the installation orientation of IC8 may be formed near the opposite side (in this example, the right side in the longitudinal direction of IC8) to the side where pin 1 of IC8 is located (in this example, the left side in the longitudinal direction of IC8).

[0581] According to this example, the mounting orientation of the IC8 can be recognized by the recess IC8b (identification portion), so that mounting errors (reverse insertion) of components can be prevented.

[0582] <Positional relationship between main control board / components and position display (Example 2)> FIG. 30(a) is a plan view for explaining the positional relationship between the component and the position indication (Example 2).

[0583] In Example 1 described using Figure 29, an example was described in which a portion of the direction identification figure 718a2 was an invisible area, but in this Example 2, the entire direction identification figure 718a2 is exposed outside the left end part of IC8 and is a visible area.

[0584] According to this example, since the entire identification mark can be visually recognized even after the component is mounted, it is possible to check at a glance that the mounting orientation of the component is correct, thereby improving convenience. Furthermore, since there are cases where at least a part of the identification mark becomes invisible when the component is mounted (for example, IC8 according to Example 1) and cases where the entire identification mark becomes visible even when the component is mounted (for example, IC8 according to Example 2), when a fraudulent person fraudulently mounts a component, the fraudulent act may be discovered based on the visibility of the identification mark, and the fraudulent act may be prevented in advance. Furthermore, there are cases where a mistake in the component can be noticed based on the visibility of the identification mark.

[0585] In this example, the length L5 from the left end of the IC8 in the left visible area is longer than the length L6 from the right end of the IC8 in the right visible area (L5>L6).

[0586] <Positional relationship between main control board / components and position display (Modification 1 of Example 2)> FIG. 30(b) is a plan view for explaining the positional relationship between the component and the position indication (Modification 1 of Example 2).

[0587] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 2, so that the length L5 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 is made the same as the length L5 from the right end of IC8 in the right visible area of ​​the contour figure 718a1.

[0588] According to this example, the width of the position indication that is exposed to the outside and visible is the same length in the longitudinal direction of the IC, so that the position indication can be used as a guide to accurately position the IC in the longitudinal direction, thereby improving convenience when mounting components.

[0589] <Positional relationship between main control board / components and position display (Modification 2 of Example 2)> FIG. 30(c) is a plan view for explaining the positional relationship between the component and the position indication (Modification 2 of Example 2).

[0590] In this example, the length of the right side in the longitudinal direction of the contour graphic 718a1 is made longer than that of the second example, so that the length L7 from the right end of the IC8 in the right visible area of ​​the contour graphic 718a1 is made longer than the length L5 from the left end of the IC8 in the left visible area of ​​the contour graphic 718a1 (L5 <L7)。

[0591] In this example, the width of the position indication that is exposed to the outside and visible is longer on one side of the IC in the longitudinal direction than on the other side, so that it is possible to place components near the IC on one side of the IC, while printing a large, conspicuous position indication on the other side of the IC, thereby increasing convenience when installing components.

[0592] <Positional relationship between main control board / components and position display (Modification 3 of Example 2)> FIG. 30(d) is a plan view for explaining the positional relationship between the component and the position indication (Modification 3 of Example 2).

[0593] In this example, the length of the right longitudinal side of the contour figure 718a1 is made shorter than in Example 2, so that the contour figure 718a1 is not exposed to the outside from the left end of the IC8, and there is no visible area on the right side of the contour figure 718a1.

[0594] According to this example, the area of ​​the position marking exposed to the outside on one longitudinal side of the IC is reduced, making it possible to print other position markings or mount other components on that side of the IC, thereby making effective use of the limited area on the board.

[0595] <Positional relationship between main control board / components and position display (Example 3)> FIG. 31(a) is a plan view for explaining the positional relationship between the component and the position indication (Example 3).

[0596] In Example 1 described using Figure 29, an example was shown in which a notch portion IC8a was formed in IC8. However, in this Example 3, instead of the notch portion IC8a, an elliptical recess IC8c (identification portion) is formed which allows the installation orientation of IC8 to be identified.

[0597] The maximum width W1 of the opening end of the orientation identification graphic 718a2 is configured to be greater than the maximum width W3 in the short direction of the recess IC8c of the IC8 (W1>W3).

[0598] In this example, the length L8 from the left end of the IC8 in the left visible area is longer than the length L9 from the right end of the IC8 in the right visible area (L8>L9).

[0599] <Positional relationship between main control board / components and position display (Modification 1 of Example 3)> FIG. 31(b) is a plan view for explaining the positional relationship between the component and the position indication (Modification 1 of Example 3).

[0600] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 3, so that the length L8 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 is made the same as the length L8 from the right end of IC8 in the right visible area of ​​the contour figure 718a1.

[0601] According to this example, the width of the position indication that is exposed to the outside and visible is the same length in the longitudinal direction of the IC, so that the position indication can be used as a guide to accurately position the IC in the longitudinal direction, thereby improving convenience when mounting components.

[0602] <Positional relationship between main control board / components and position display (Modification 2 of Example 3)> FIG. 31(c) is a plan view for explaining the positional relationship between the component and the position indication (Modification 2 of Example 3).

[0603] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 3, so that the length L10 from the right end of IC8 in the right visible area of ​​the contour figure 718a1 is made longer than the length L8 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 (L10>L8).

[0604] In this example, the width of the position indication that is exposed to the outside and visible is longer on one side of the IC in the longitudinal direction than on the other side, so that it is possible to place components near the IC on one side of the IC, while printing a large, conspicuous position indication on the other side of the IC, thereby increasing convenience when installing components.

[0605] <Positional relationship between main control board / components and position display (Modification 3 of Example 3)> FIG. 31(d) is a plan view for explaining the positional relationship between the component and the position indication (third modification of the third embodiment).

[0606] In this example, the length of the right longitudinal side of the contour figure 71a1 is made shorter than in Example 3, so that the contour figure 718a1 is not exposed to the outside from the left end of the IC8, and there is no visible area on the right side of the contour figure 718a1.

[0607] According to this example, the area of ​​the position marking exposed to the outside on one longitudinal side of the IC is reduced, making it possible to print other position markings or mount other components on that side of the IC, thereby making effective use of the limited area on the board.

[0608] <Positional relationship between main control board / components and position display (Example 4)> FIG. 32(a) is a plan view for explaining the positional relationship between the component and the position indication (Example 4).

[0609] In Example 1 described using Figure 29, an example was shown in which a notch portion IC8a was formed in IC8. However, in this Example 4, instead of the notch portion IC8a, a notch portion IC8d (identification portion) that can identify the installation orientation of IC8 is formed.

[0610] The maximum height H2 from the bottom to the opening edge of the cutout portion IC8d of the IC8 is configured to be greater than the maximum height H1 from the bottom to the opening edge of the orientation identifying graphic 718a2 (H2>H1).

[0611] In this example, the length L11 from the left end of the IC8 in the left visible area is longer than the length L12 from the right end of the IC8 in the right visible area (L11>L12).

[0612] <Positional relationship between main control board / components and position display (Modification 1 of Example 4)> FIG. 32(b) is a plan view for explaining the positional relationship between the component and the position indication (Modification 1 of Example 4).

[0613] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 4, so that the length L11 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 is made the same as the length L11 from the right end of IC8 in the right visible area of ​​the contour figure 718a1.

[0614] According to this example, the width of the position indication that is exposed to the outside and visible is the same length in the longitudinal direction of the IC, so that the position indication can be used as a guide to accurately position the IC in the longitudinal direction, thereby improving convenience when mounting components.

[0615] <Positional relationship between main control board / components and position display (Modification 2 of Example 4)> FIG. 32(c) is a plan view for explaining the positional relationship between the component and the position indication (Modification 2 of Example 4).

[0616] In this example, the length of the longitudinal right side of the contour figure 718a1 is made longer than in Example 4, so that the length L13 from the right end of IC8 in the right visible area of ​​the contour figure 718a1 is made longer than the length L11 from the left end of IC8 in the left visible area of ​​the contour figure 718a1 (L13>L11).

[0617] In this example, the width of the position indication that is exposed to the outside and visible is longer on one side of the IC in the longitudinal direction than on the other side, so that it is possible to place components near the IC on one side of the IC, while printing a large, conspicuous position indication on the other side of the IC, thereby increasing convenience when installing components.

[0618] <Positional relationship between main control board / components and position display (Modification 3 of Example 4)> FIG. 32(d) is a plan view for explaining the positional relationship between the component and the position indication (Modification 3 of Example 4).

[0619] In this example, by making the length of the contour figure 718a1 on the right side in the longitudinal direction shorter than that in the fourth example, the contour figure 718a1 is configured not to be exposed to the outside from the left end of the IC8, and the right visible area of the contour figure 718a1 is configured not to exist.

[0620] According to this example, since the area of the position display exposed to the outside on one side in the longitudinal direction of the IC is reduced, it becomes possible to print other position displays or mount other components on one side of the IC, and the limited area on the substrate can be effectively utilized.

[0621] <Main control board / positional relationship between components and position display (Example 5)> FIG. 33(a) is a plan view for explaining the positional relationship between components and position display (Example 5).

[0622] In the above Examples 1 to 4, the IC8 (motor driver IC) and its position display were described. In this Example 5, an IC2 (reset IC) having a smaller shape than the IC8 and its position display will be described.

[0623] As described above, the position display 712 of the IC2 is composed of a graphic display 712a imitating the appearance of the IC2, an identification display 712b capable of identifying the type and management number of the component, and a pin 1 identification display 712c capable of identifying the position of the pin 1.

[0624] The graphic display 712a is composed of a rectangular contour figure 712a1 representing the contour of the IC2 and a direction identification figure 712a2 (identification display) in the form of an elongated recess imitating the appearance of the notch portion IC2a (identification portion) of the IC2.

[0625] The maximum width W4 of the opening end of the direction identification figure 712a2 is narrower than the maximum width W5 of the opening end of the notch portion IC2a of the IC2 (W4 < W5), but the maximum height H3 from the bottom to the opening end of the direction identification figure 712a2 is configured to be higher than the maximum height H4 from the bottom to the opening end of the notch portion IC2a of the IC2 (H3 > H4).

[0626] In this example, since IC2 is a small component, the maximum width of the opening end of the direction identification figure 712a2 cannot be made large. However, the maximum height H3 from the bottom to the opening end of the direction identification figure 712a2 of IC2 is configured to be higher than the maximum height H4 from the bottom to the opening end of the cutout portion IC2a ​​of IC2 (H3>H4), which makes the position indication stand out and improves convenience when mounting the component.

[0627] In this example, the length L14 from the left end of the IC2 in the left visible area is longer than the length L15 from the right end of the IC2 in the right visible area (L14>L15).

[0628] <Positional relationship between main control board / components and position display (Modification 1 of Example 5)> FIG. 33(b) is a plan view for explaining the positional relationship between the component and the position indication (Modification 1 of the fifth embodiment).

[0629] In this example, the length of the longitudinal right side of the contour figure 712a1 is made longer than in Example 5, so that the length L14 from the left end of IC2 in the left visible area of ​​the contour figure 712a1 is made the same as the length L14 from the right end of IC2 in the right visible area of ​​the contour figure 712a1.

[0630] According to this example, the width of the position indication that is exposed to the outside and visible is the same length in the longitudinal direction of the IC, so that the position indication can be used as a guide to accurately position the IC in the longitudinal direction, thereby improving convenience when mounting components.

[0631] <Positional relationship between main control board / components and position display (Modification 2 of Example 5)> FIG. 32(c) is a plan view for explaining the positional relationship between the component and the position indication (Modification 2 of Example 5).

[0632] In this example, the length of the longitudinal right side of the contour figure 712a1 is made longer than in Example 5, so that the length L16 from the right end of IC2 in the right visible area of ​​the contour figure 712a1 is made longer than the length L14 from the left end of IC2 in the left visible area of ​​the contour figure 712a1 (L16>L14).

[0633] In this example, the width of the position indication that is exposed to the outside and visible is longer on one side of the IC in the longitudinal direction than on the other side, so that it is possible to place components near the IC on one side of the IC, while printing a large, conspicuous position indication on the other side of the IC, thereby increasing convenience when installing components.

[0634] <Positional relationship between main control board / components and position display (Modification 3 of Example 5)> FIG. 32(d) is a plan view for explaining the positional relationship between the component and the position indication (Modification 3 of Example 5).

[0635] In this example, the length of the longitudinal right side of the contour figure 712a1 is made shorter than in Example 5, so that the contour figure 712a1 is not exposed to the outside from the left end of IC2, and there is no visible area on the right side of the contour figure 712a1.

[0636] According to this example, the area of ​​the position marking exposed to the outside on one longitudinal side of the IC is reduced, making it possible to print other position markings or mount other components on that side of the IC, thereby making effective use of the limited area on the board.

[0637] <Positional relationship between main control board / components and position display (Example 6)> FIG. 32(e) is a plan view for explaining the positional relationship between the component and the position indication (Example 6).

[0638] In the above embodiments 1 to 4, IC8 (motor driver IC) and its positional display were described, and in the above embodiment 5, IC2 (reset IC) and its positional display were described. In this embodiment 6, however, IC16 (test logic IC), which is smaller in shape than IC8 and IC2, and its positional display are described.

[0639] As described above, the position display 719 of IC16 is composed of a graphic display 719a that imitates the appearance of IC16, an identification display 719b that enables identification of the type and management number of IC16, and a pin 1 identification display 719c that enables identification of the position of pin 1.

[0640] The graphic display 719a is made up of a rectangular outline graphic 719a1 that represents the outline of the IC 16, and a direction identification graphic 719a2 (identification display) that indicates the mounting direction of the IC 16.

[0641] In this example, the maximum width W6 of the opening end of the direction identification figure 719a2 is configured to be wider than the maximum width W7 of the recess IC16a of the IC16 (W6>W7), and is configured to be more than half the length of the short-side width of the contour figure 719a1 and the IC16.

[0642] If the component is small, the area for indicating its position will also be small, which may make it difficult to recognize the installation orientation of the component. However, according to this example, the maximum width W6 of the opening end of the direction identification figure 719a2 is configured to be more than half the length of the short-side width of the outline figure 719a1 or IC16, which makes the position indication stand out and improves convenience when mounting the component.

[0643] In this example, the length L20 from the left end of IC16 in the left visible area is shorter than the length L1 from the left end of IC8 in the left visible area of ​​IC8 shown in FIG. 29(a) and the length L14 from the left end of IC2 in the left visible area of ​​IC2 shown in FIG. 33(a) (L20 <L1,L14)。

[0644] According to this example, while it is possible to arrange components in the vicinity of a component (IC16), the identification display (direction identification graphic 719a2) can be printed so as to be highly conspicuous, enhancing the convenience during component mounting.

[0645] Also, in this example, the length L22 from one side in the short side direction of the graphic display 719a to one side in the short side direction of the package (main body part) of the IC16 is made shorter than the length L21 from one side in the short side direction of the graphic display 712a shown in FIG. 33(c) to one side in the short side direction of the package (main body part) of the IC2 (L22 < L21).

[0646] According to this example, the position display (graphic display 719a) corresponding to the component (IC16) can be printed so as to be highly conspicuous, enhancing the convenience during component mounting.

[0647] <Main control board / Positional relationship between components and position display / Summary> As described above, the gaming table according to the present embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming table provided with a board (for example, the main control board 600 shown in FIGS. 25 and 26) on which a plurality of components are mounted. The plurality of components include a first component (for example, the IC8 (motor driver IC) shown in FIG. 27). An identification part (for example, the notch part IC8a shown in FIG. 27) capable of suggesting the position of the first pin of the first component is formed on the first component. A display indicating the mounting position of the first component (hereinafter referred to as "first display". For example, the position display 718 (graphic display 718a, identification display 718b, first pin identification display 718c) shown in FIG. 27) is provided on the board. The first display is configured to have an identification display (hereinafter referred to as "first identification display". For example, the direction identification graphic 718a2 shown in FIG. 27) capable of identifying the mounting orientation (mounting direction) of the first component. In a state where the first component is mounted on the board (hereinafter referred to as "first state"), at least a part of the visibility of the first display is obstructed by the first component, but at least a part of the first identification display is visible. The gaming table is characterized by this.

[0648] According to the gaming machine of this embodiment, by making a part of the position indication invisible by the part, it is possible to print other position indications or mount other parts near the part, and it is possible to effectively utilize the mounting surface of the board, which has limited space. In addition, since it is possible to easily check a part of the identification indication even after mounting the part, it is possible to check at a glance that the mounting direction of the part is correct, and it is possible to improve convenience.

[0649] Generally, components are mounted automatically by a machine, and components arranged in a predetermined orientation are fed into the machine to be mounted on the board in succession. However, if the orientation of the components is reversed, the components may be mounted in the opposite direction to their original orientation. According to the present invention, even if such a component mounting error (reverse insertion) occurs, the mounting orientation of the components can be easily visually confirmed. Also, during the development stage, components may be mounted manually instead of by machine, but according to the present invention, the mounting orientation of the components can be easily visually confirmed even during the development stage.

[0650] The "identification feature" of the present invention may be any part capable of indicating the position of the No. 1 pin of a part, and may be a concave part that is recessed inward into the part, a convex part that protrudes outward into the part, a notch formed in the corner of the part, a mark, number, symbol, etc. on the part, a sticker affixed to the part, an engraving on the part, etc., or it may be one or more of these.

[0651] Furthermore, the first component may have a plurality of portions (pins), one of the plurality of portions (pins) being a specific portion (pin 1), the first component may have an identification portion that identifies the specific portion (pin 1), the substrate may have a portion that corresponds to the specific portion (pin 1), and the first component may be fixed so as to electrically connect the specific portion (pin 1) to the identification portion.

[0652] In addition, the "indication that enables identification of the installation orientation of a part" according to the present invention may be a graphic that imitates at least a part of the appearance of the part, a graphic that represents at least a part of the outline of the part, letters or symbols indicating the model number, control number, or name of the part, a number indicating the pin number of the part, a number or symbol indicating pin 1 of the part, or it may be one or more of these.

[0653] In addition, the "identification mark" of the present invention may be any mark that enables the installation orientation of a part to be identified, and may be a mark that has the same shape as the identification part of the part, a mark that has a similar shape to the identification part of the part, a mark that consists of part of the identification part of the part, a mark that differs in shape from the identification part of the part but enables the installation orientation of the part to be identified, a mark applied by a method other than silk printing (for example, engraving), etc., or it may be one or more of these.

[0654] Furthermore, the first identification mark may be a recessed-shaped figure having an opening, and the maximum width of the opening of the first identification mark (e.g., the maximum width indicated by symbol W1 in Figure 27(a)) may be wider than the maximum width of the opening of the first identification part (e.g., the maximum width indicated by symbol W2 in Figure 27(a)).

[0655] With this configuration, the installation orientation of the component can be easily confirmed before the component is mounted, preventing installation errors (reverse insertion) of the component, and the identification markings can be easily confirmed even after the component is mounted, so that it is possible to confirm at a glance that the installation orientation of the component is correct, thereby increasing convenience.

[0656] Also, the first component may prevent at least a portion of the first identification mark from being visible.

[0657] With this configuration, the area of ​​the position indication exposed to the outside of the component is reduced, making it possible to print other position indications or mount other components on the outside of the component, thereby making effective use of the mounting surface of the board, which has limited space.

[0658] The plurality of components may include a second component (e.g., IC8 (motor driver IC) shown in FIG. 28), the second component may have an identification portion (e.g., cutout portion IC8a shown in FIG. 28) that can indicate the position of pin 1 of the second component, the board may have an indication indicating the mounting position of the second component (hereinafter referred to as the "second indication", for example, position indication 718 (graphical indication 718a, identification indication 718b, pin 1 identification indication 718c) shown in FIG. 28), the second indication may have an identification indication (hereinafter referred to as the "second identification indication", for example, direction identification graphic 718a2 shown in FIG. 28) that can identify the mounting orientation (mounting direction) of the second component, and all of the second identification indication may be visible when the second component is mounted on the board.

[0659] With this configuration, since the entire identification marking can be seen even after the component is mounted, it is possible to check at a glance that the mounting orientation of the component is correct, thereby improving convenience. Furthermore, since at least a part of the identification marking may become invisible when the component is mounted, and the entire identification marking may be visible even when the component is mounted, in the case where a fraudulent person fraudulently mounts a component, the fraudulent act may be discovered based on the visibility of the identification marking, and the fraudulent act may be prevented in advance. Furthermore, the visibility of the identification marking may allow a mistake in the component to be noticed.

[0660] The substrate may also include a capacitor (e.g., capacitor C35 shown in FIG. 27(b)), and at least a power supply wiring pattern (e.g., power supply wiring pattern 604a shown in FIG. 27(b)) and a ground wiring pattern (e.g., GND wiring pattern 604b shown in FIG. 27(b)) may be formed on the rear surface of the substrate, the power supply wiring pattern and the ground wiring pattern may be formed along the longitudinal direction of the first component, and the capacitor may be arranged parallel to the short side direction of the first component in a position that does not overlap with the first identification mark (or the second identification mark) of the substrate.

[0661] With this configuration, the capac...
