DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] <<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.

[0012] <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).

[0013] 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.

[0014] 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. 4). 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.

[0015] 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.

[0016] A backlight 264 (see FIG. 18) for illuminating each symbol displayed in the symbol display window 113 is disposed on the back of each of the reels 110 to 112 (details will be described later). In addition, an optical sensor (also called an index sensor, not shown) consisting of a light-emitting section and a light-receiving section is provided near each of the reels 110 to 112 inside the slot machine 100, and a light-shielding piece of a certain length provided on the reel passes between the light-emitting section and the light-receiving section of 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 to 112 are stopped so that the target symbol is displayed on the winning line.

[0017] The notification lamp 123 is a lamp that notifies the player that, for example, a specific winning combination (specifically, special combination 1 or special combination 2) has been internally won in an internal lottery described later, or that a bonus game is being played (special combination 1·2 game state is in progress). The game medal insertion possible lamp 124 is a lamp that notifies the player that a game medal can be inserted. The replay lamp 122 is a lamp that notifies the player that the current game can be played again (no medal insertion is required) if a replay, which is one of the winning combinations, was won in the previous game. The reel panel lamp 128 is a lamp for presentation purposes.

[0018] The bet buttons (first operating means) 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, and 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. The game medal insertion lamp 129 lights up the number of lamps corresponding to the number of medals inserted, and when a specified number of medals have been inserted, the game start lamp 121 lights up to indicate that a game start operation is possible.

[0019] 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.

[0020] 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.

[0021] The stored number display 125 is a display for displaying the number of medals electronically stored in the slot machine 100. The game information display 126 is a display for displaying various internal information (for example, the number of medals paid out during a bonus game) in numerical form. The payout number display 127 is a display for displaying the number of medals paid out to a player as a result of winning some kind of winning combination, and is also used as an instruction monitor for performing push order performance. In this example, the stored number display 125, the game information display 126, and the payout number display 127 are seven-segment (SEG) displays.

[0022] The start lever (second operating means) 135 is a lever-type switch for starting the rotation of the reels 110 to 112. That is, when the desired number of medals is 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.

[0023] 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.

[0024] 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").

[0025] 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).

[0026] 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).

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] <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.

[0033] As explained using Figure 1, when viewed by a player, the symbols on the reels 110-112 are displayed vertically in roughly three windows 113 provided in front of each of the reels 110-112, so that a total of nine symbols are visible.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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).

[0038] 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 combination described with reference to Fig. 5 is displayed (whether or not it is aligned). The winning line that is effective (hereinafter, may be simply referred to as "effective line") is predetermined according to the number of medals bet as gaming media.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] <Control Unit> Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to Fig. 3. Note that Fig. 3 shows a circuit block diagram of the control unit.

[0043] The control unit of the slot machine 100 is broadly composed of a main control unit 300 (first control means) that mainly controls game play, a first sub-control unit 400 (second control means) 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 (second control means) that controls various devices based on the commands sent from the first sub-control unit 400.

[0044] <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.

[0045] 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.

[0046] 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).

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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, medal insertion possible lamp 124, re-play lamp 122, medal insertion lamp 129, game start lamp 121, number of stored medals indicator 125, game information indicator 126, payout number indicator 127).

[0054] 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 652 provided in an external hall computer (not shown) or the like via this information output circuit 334.

[0055] 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).

[0056] 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.

[0057] <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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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).

[0064] 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.

[0065] 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.

[0066] 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.

[0067] <Pattern Arrangement> Next, the arrangement of symbols on each of the reels 110 to 112 will be described with reference to Fig. 4. Fig. 4 is a plan view showing the arrangement of symbols on each of the reels (left reel 110, center reel 111, right reel 112).

[0068] 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.

[0069] <Types of winning roles> Next, the types of winning combinations of the slot machine 100 will be described with reference to Fig. 5. Fig. 5 is a diagram showing the types of winning combinations, the names of the condition devices, the symbol combinations corresponding to each winning combination, the payout amounts, and remarks.

[0070] The winning combinations of the slot machine 100 include special combinations (special combination 1, special combination 2) and general combinations (replay combinations 1 to 3, small combinations 1 to 5). The types of winning combinations are not limited to these combinations and can be arbitrarily adopted. In FIG. 5, some of the winning combinations are omitted.

[0071] <Types of winning roles / special roles> Among the winning combinations in this embodiment, the special combination 1 and the special combination 2 are combinations that transition to a special game state in which a predetermined benefit is given to the player. The replay combination is a combination that allows replay without inserting a new medal (a combination that gives replay). These winning combinations are sometimes called "operation combinations."

[0072] In addition, in this embodiment, "winning" also includes the case where a pattern combination of an operating role that does not involve a medal payout (does not involve the payment of medals) is displayed on the winning line, and includes, for example, winning special role 1, special role 2, and re-play role.

[0073] Special Role 1 and Special Role 2 are winning roles that transition the game state to Special Role 1·2 internal winning state (RT3) by internal winning, and transition to Special Role 1·2 game state (RT4) by winning. In addition, if more than the specified number of medals (for example, 200 medals) are paid out in the Special Role 1·2 game state (RT4), the game state transitions to the low replay probability state (RT1). Each game state (RT1 to RT4) will be described later.

[0074] The symbol combination corresponding to special role 1 (BB) is "Seven 1 symbol-Seven 1 symbol-Seven 1 symbol" or "Seven 2 symbol-Seven 2 symbol-Seven 2 symbol", and the symbol combination corresponding to special role 2 (RB) is "BAR symbol-BAR symbol-BAR symbol".

[0075] When special role 1 or special role 2 is internally won, the special role internal win flag corresponding to this internally won role is set to ON (stored in a specified area of ​​the RAM 308 of the main control unit 300). This flag is maintained in the ON state until the internally won role is won, and the player is more likely to win the internally won role in the next and subsequent games. In other words, in a game in which special role 1 or special role 2 is internally won, even if the player does not win the special role, the player will be in a state of internally winning the special role in the next and subsequent games, and the symbol combination corresponding to the special role will be in a state of being more likely to win.

[0076] <Type of winning role / replay role> The replay roles 1 to 3 are winning roles (operating roles) that allow you to play the next game without inserting a medal (game medium) by winning, and no medals are paid out. The corresponding symbol combinations are as shown in FIG.

[0077] The replay role may be any role that allows the player to play the next game without inserting a medal. Therefore, for example, when the replay role is won, medals may be automatically inserted in the next game (the number of medals inserted is reset in the medal insertion number storage area), or the medals inserted in the game in which the replay role is won may be carried over and used in the next game. The special replay described later is also one of the replay roles.

[0078] <Winning Roles / Small Roles> Small prize 1 to small prize 5 are winning prizes in which a predetermined number of medals are paid out (there is a payout number).

[0079] The minor prize 1 (watermelon) is a winning prize in which the symbol combination of "watermelon symbol-watermelon symbol-watermelon symbol" is displayed stationary on the winning line L1, and five medals are paid out.

[0080] The minor prize 2 (Cherry) is a prize in which the symbol combination "Cherry symbol-ANY-ANY" is displayed on the winning line L1 and two medals are paid out. Note that the symbol combination "Cherry symbol-ANY-ANY" only requires that the symbol on the left reel 110 is a "Cherry symbol," and the symbols on the center reel 111 and right reel 112 can be any symbol.

[0081] Hereinafter, these small prize 1 (watermelon) and small prize 2 (cherry) may be collectively referred to as "rare prizes", however, rare prizes are not limited to these winning prizes, and may be either one of the winning prizes, or may include other winning prizes.

[0082] In addition, if you win a rare role in the AT state described below, a lottery is held to add the number of games or the number of sets (making it easier to win the lottery). On the other hand, even if you win a rare role in the ED state, a lottery is not held to add the number of games or the number of sets.

[0083] The small prize 3 (push order bell) is composed of six types of winning prizes, small prize 3a to small prize 3f. In this example, by lottery, with a predetermined probability (about 1 / 6 in this example, common to all settings), one of the winning prizes, small prize 3a to small prize 3f, is internally won, and if the operation sequence (push order) of the stop operation by the stop buttons 137 to 139 matches the winning prize that has been internally won, the prize is won, and 12 medals are paid out. In other words, the small prize 3 (push order bell) is an operation mode result (winning role) whose advantage differs depending on the operation mode of the stop buttons (stop buttons) 137 to 139.

[0084] Minor win 4 (common bell) is a winning combination in which the symbol combination of "bell symbol-bell symbol-bell symbol" is displayed stopped on the winning line L1, regardless of the operation order (press order) or timing of the stop operations using the stop buttons 137 to 139, and 12 medals are paid out.

[0085] The small combination 5 (single combination) is a winning combination where, regardless of the operation order (pressing order) or operation timing of the stop operation by the stop buttons 137 to 139, the symbol combination of "Replay symbol - Replay symbol - Blank 1 symbol" is stopped and displayed on the winning line L1, and one medal is paid out.

[0086] <Types of RT-based game states> Next, the types and transitions of RT-based game states in the slot machine 100 will be described.

[0087] <Replay low probability state (RT1)> The replay low probability state (RT1) is the default RT-based game state (hereinafter also referred to as the "normal game state") that is first set immediately after the power-on of the slot machine 100, etc., and is a game state that is relatively disadvantageous for the player compared to other game states.

[0088] In this example, in this replay low probability state (RT1), when winning the replay combination 2 (upgraded replay 1) or replay combination 3 (upgraded replay 2), it transitions to the replay high probability state (RT2) described later. Also, in this replay low probability state (RT1), when internally winning the special combination 1 or special combination 2, it transitions to the special combination 1·2 internal winning state (RT3) described later.

[0089] <Replay high probability state (RT2)> The replay high probability state is a game state where the internal winning probability of the replay is higher than that in the replay low probability state (RT1).

[0090] In this example, in this replay high probability state (RT2), when internally winning the special combination 1 or special combination 2, it transitions to the special combination 1·2 internal winning state (RT3) described later.

[0091] <Special combination 1·2 internal winning state (RT3)> The internal winning state (RT3) of special role 1 or 2 is a state in which the internal winning flag corresponding to special role 1 or special role 2 is set to on. When the player performs a stop operation at a predetermined timing, a symbol combination corresponding to the special role corresponding to this flag can be displayed, which is a gaming state.

[0092] In this example, in this internal winning state (RT3) of special role 1 or 2, when winning a prize in special role 1 or special role 2, it transitions to the special gaming state (RT4) described later.

[0093] <Special gaming state (RT4)> The special gaming state (RT4) is the most advantageous gaming state for the player among all gaming states. In this example, in the special gaming state (RT4), when a specified number of medals (for example, 200 medals) are paid out, it transitions to the low-probability replay state (RT1).

[0094] Note that in this example, the end condition of the special gaming state (RT4) is not particularly limited. For example, it may be when winning an internal prize for a specified role, when there are winnings a specified number of times (for example, 8 times), or when a specified number of games (for example, 6 times) have been played.

[0095] <Transition of AT-based gaming states> Next, the AT-based gaming states will be described.

[0096] The AT-based gaming states are roughly classified into a low-navigation state and a high-navigation state. The low-navigation state is a state where the probability of executing the operation navigation is low, and is also referred to as the normal mode, non-advantageous section, or normal section. The high-navigation state is a state where the probability of executing the operation navigation is higher than that of the low-navigation state, and is also referred to as the AT mode and advantageous section.

[0097] Here, the operation navigation refers to an effect that notifies the stop operation mode (for example, the correct operation order and the timing of the stop operation) of the stop buttons 137 to 139 in order to obtain medals or maintain an advantageous gaming state. For example, an effect that notifies the correct operation order of the pressing order role (for example, minor role 3 (pressing order bell LCR)) (for example, an effect that displays the characters "left → middle → right") and the like are applicable.

[0098] When a player performs a stop operation according to the operation content of the operation navigation, the player will get a favorable result, so the high navigation state is a more favorable gaming state for the player than the low navigation state. Here, favorable specifically means that the ratio of the total number of gaming media paid out by the gaming machine to the total number of gaming media used by the player as the number of bets when playing for a specified period of time, that is, the so-called payout rate (ball payout rate), is favorable.

[0099] In this example, the low navigation state is a state in which the probability of execution of operation navigation is low, and the high navigation state is a state in which the probability of execution of operation navigation is higher than in the low navigation state; however, the low navigation state may also be a state in which operation navigation is not executed, and the high navigation state may be a state in which operation navigation is executed.

[0100] Each game state of the AT system is subdivided and managed, and these are called presentation states. In detail, the presentation state of the low navigation state is the normal game state, and the presentation state of the high navigation state includes the normal state, the confirmation notification state, the judgement state, the pullback state, the AT1 state, the AT2 state, and the ED (ending) state. In principle, the AT1 state, the AT2 state, and the ED state are the states in which the number of balls released increases.

[0101] In this embodiment, when a certain condition is met in the normal game state in the low navigation state (for example, when a winning combination other than a miss is won), the game transitions to the normal state in the high navigation state. After that, the game transitions in the order of, for example, the confirmation notification state → AT1 state → judgement state, and there are routes from this judgement state to the normal game state or the AT2 state via the pullback state, or routes from the judgement state to the AT2 state directly.

[0102] The AT state (AT1 state, AT2 state) is a state in which AT play is possible a specified number of times (for example, 30 games per set), and is a state that is more advantageous for the player than the normal play state in a low navigation state or the normal state in a high navigation state.

[0103] In this AT game, at the start of the AT game, a set continuation lottery (for example, a lottery with a winning probability of 1 / 4) is held to determine whether or not to continue the AT game, and if the set continuation lottery is won, a predetermined number of AT games (in this example, one set of 30 games) are awarded, and the AT state is extended. Also, if the condition for transition to the normal game state is met in the AT state (in this example, when all games in the AT state have been played), the game will transition to the normal game state from the next game.

[0104] Furthermore, when the number of remaining games in the high navigation state falls below a predetermined number (for example, 20 games), the state transitions to an ED state, and in this ED state, an ED (ending) performance is executed, which suggests the end of the high navigation state.

[0105] In addition, the condition for transitioning to the ED state is not limited to the remaining games in the high navigation state being a predetermined number of games (e.g., 20 games) or less, but may be, for example, the predetermined number of games being more or less than 20 games, or may be "number of coins won + difference in expected number of coins won > 2000".

[0106] <Main processing in main control section> First, the main control unit main processing executed by the CPU 304 of the main control unit 300 will be described with reference to Fig. 6. Note that Fig. 6 is a flow chart showing the flow of the main control unit main processing.

[0107] As described above, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 338 that outputs a start signal (reset signal) when power is turned on. The CPU 304 of the basic circuit 302 that receives this start signal is reset and started by a reset interrupt, and executes the main control unit main processing shown in FIG. 6 according to a control program previously stored in the ROM 306.

[0108] When the power is turned on, first, various initial settings are performed in step S101. In these initial settings, a stack initial value is set to the stack pointer (SP) of the CPU 304, interrupt prohibition is set, the I / O 310 is initialized, various variables stored in the RAM 308 are initialized, and operation permission and initial value are set to the WDT 314.

[0109] In step S102, a bet number setting / start operation acceptance process is executed. Here, whether or not medals have been inserted is checked, and preparations are made to send an insertion command indicating that medals have been inserted. If a replay role has been won in the previous game, a process is performed to insert the same number of medals as the number of medals inserted in the previous game, so that the player does not need to insert medals. Also, a check is made as to whether or not the start lever 135 has been operated, and if the start lever 135 has been operated, the process proceeds to step S103.

[0110] In step S103, the number of inserted medals is determined, and a win line determination process is carried out to determine the valid win lines.

[0111] In step S104, the random number generated by the random number generating circuit 316 is obtained, and a winning combination internal lottery process is performed. In the winning combination internal lottery process, a winning combination lottery table stored in the ROM 306 is read according to the current game state, and an internal lottery is performed using this and the obtained random number value, and preparations are made to send an internal lottery command indicating the result of this internal lottery to the first sub-control unit 400. If any winning combination (including an operating combination) is internally won as a result of the internal lottery, the flag of that winning combination is turned on.

[0112] In step S105, a reel stop data selection process is performed to select reel stop data based on the internal lottery result of the winning combination internal lottery process. This reel stop data is stored in the ROM 306 of the main control unit 300. In step S105, preparations are made to send a reel stop data command including information about the selected reel stop data to the first sub-control unit 400.

[0113] In step S106, a presentation state control process for controlling the game state of the AT system described above is executed based on the start lever operation. In step S107, a presentation process is executed. In this presentation process, various presentations are controlled.

[0114] In step S108, a reel spinning start process is executed, and all the reels 110 to 112 start spinning.

[0115] In step S109, a reel stop control process is performed. In the reel stop control process, the stop buttons 137-139 can be accepted, and when any of the stop buttons is pressed, a stop table of reel stop data is referenced to stop the reel corresponding to the pressed stop button, and any of the reels 110-112 is stopped according to the number of pull-in frames set in the stop table. When all the reels 110-112 have stopped, the process proceeds to step S110. In addition, in this step S109, for each stop operation, preparations are made to send a stop button acceptance command related to the stop button 137-139 that was operated to stop (more specifically, for the first stop operation, a stop button acceptance 1 command, for the second stop operation, a stop button acceptance 2 command, and for the third stop operation, a stop button acceptance 3 command) to the first sub-control unit 400, and for each reel stop, preparations are made to send a reel stop command related to the reel stop position (more specifically, for the first stopped reel, a reel stop 1 command, for the second stop operation, a reel stop 2 command, and for the third stop operation, a reel stop 3 command) to the first sub-control unit 400.

[0116] In step S110, a winning determination process is performed to determine whether or not a winning combination has been achieved. In this winning determination process, if a symbol combination corresponding to a winning combination is displayed on the activated winning line 114, it is determined that the winning combination has been achieved. For example, if "Bell-Bell-Bell" is aligned on the activated winning line, it is determined that the minor combination 3 (Bell) has been achieved. In addition, in this step S110, preparations are made to send a winning determination command indicating the result of the winning determination to the first sub-control unit 400.

[0117] In step S111, a medal awarding process is performed. In the medal awarding process, if any winning combination that provides a payout is achieved, medals in the number corresponding to the winning combination are paid out according to the number of winning lines.

[0118] In step S112, a game state control process is performed. In the game state control process, the process related to the transition of each game state of the RT system is performed, and the game state is transitioned when the start condition or end condition is satisfied. In addition, preparation is made for sending a game state command including information indicating the current game state of the RT system.

[0119] In step S113, the controller 10 executes a presentation state control process for controlling the game state of the AT system described above. In step S114, the controller 10 executes a high-level navigation state end process for ending the high-level navigation state.

[0120] This completes one game. After this, the game progresses by returning to step S102 and repeating the above-mentioned process. The various commands prepared in each of the above steps are transmitted in the command setting and transmission process (step S206 in FIG. 7) of the main control unit timer interrupt process described later.

[0121] <Main control unit timer interrupt processing> Next, a main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to Fig. 7. Note that Fig. 7 is a flow chart showing the flow of the main control unit timer interrupt process.

[0122] The main control unit 300 is equipped with a counter timer 312 that generates a timer interrupt signal at a predetermined period (approximately once every 2 ms in this embodiment), and this timer interrupt signal is used as a trigger to start main control unit timer interrupt processing at the predetermined period.

[0123] In step S201, a timer interrupt start process is performed, which includes processes such as temporarily saving the values ​​of each register of the CPU 304 in a stack area.

[0124] In step S202, the WDT 314 is restarted periodically (in this embodiment, once every approximately 2 ms, which is the period of the main control unit timer interrupt) so that the count value of the WDT 314 does not exceed the initial setting value (32.8 ms in this embodiment) and a WDT interrupt does not occur (so that a processing abnormality is not detected).

[0125] In step S203, an input port state update process is performed. In this input port state update process, detection signals from the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310, the presence or absence of the detection signals is monitored, and the detection signals are stored in signal state storage areas partitioned for each of the various sensors 318 in the RAM 308.

[0126] In step S204, various game processes are executed, and processes corresponding to the interrupt status are executed. In step S2005, a timer update process is executed. More specifically, various timers are updated according to their respective time units.

[0127] In step S206, a command setting and transmission process is performed, and various commands that have been prepared for transmission are transmitted to the first sub-control unit 400. In the first sub-control unit 400, the command type included in the received output schedule information makes it possible to determine presentation control in response to changes in game control in the main control unit 300, and it becomes possible to determine the content of presentation control based on the command data information included in the output schedule information.

[0128] In step S207, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 652, which is separate from the slot machine 100, via the information output circuit 334.

[0129] In step S208, device monitoring processing is performed. In this device monitoring processing, first, the signal states of the various sensors 318 stored in the signal state storage area in step S203 are read out to monitor for errors related to medal insertion abnormalities, medal payout abnormalities, etc., and if an error is detected (not shown), error processing is executed. Furthermore, depending on the current game state, settings are made for the medal selector 170 (a medal blocker operated by a solenoid provided in the medal selector 170), various lamps 339, and various seven-segment (SEG) displays.

[0130] In step S209, it is monitored whether the low voltage signal is ON or not. If the low voltage signal is ON (if a power interruption is detected), the process proceeds to step S211, and if the low voltage signal is OFF (if a power interruption is not detected), the process proceeds to step S210.

[0131] In step S210, various processes are performed to end the timer interruption end process. In this timer interruption end process, the values ​​of each register temporarily saved in step S2001 are set back to the original registers, etc. Then, the process returns to the main process of the main control unit shown in FIG.

[0132] On the other hand, in step S211, specific variables and stack pointers for returning to the state at the time of power outage when power is restored are saved as recovery data in a specified area of ​​RAM 308, power outage processing such as initialization of input / output ports is performed, and then the process returns to the main processing of the main control unit shown in Figure 7.

[0133] <Processing of the first sub-control unit> Next, the processing of the first sub-control unit 400 will be explained using Figure 8. Figure 8(a) is a flowchart of the main processing executed by the CPU 404 of the first sub-control unit 400. Figure 8(b) is a flowchart of the command reception interrupt processing of the first sub-control unit 400. Figure 8(c) is a flowchart of the timer interrupt processing of the first sub-control unit 400.

[0134] First, the main processing of the first sub-control unit 400 will be explained using FIG. 8(a).

[0135] When the power is turned on, an initialization process is first executed in step S301. In this initialization process, the input / output ports are initially set, and a storage area in the RAM 408 is initialized. In this process, an area for storing internal win information, which is information that indicates the result of an internal win, and an area for storing RT update information, which is information that indicates the game status, are provided in the RAM 408.

[0136] In step S302, it is determined whether the timer variable is 10 or more, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step S3003. In step S303, 0 is substituted for the timer variable. In step S304, command processing, which is processing corresponding to each command received from the main control unit 300, is executed.

[0137] In step S305, a performance control process is performed. Here, preparation for performance is performed according to the performance reservation information in the performance reservation area provided in the RAM 408. This preparation includes, for example, processing such as reading the performance data from the ROM 406, and updating the performance data if it is necessary to update the performance data.

[0138] In step S306, sound control processing is performed based on the processing result of step S305. For example, if the performance data read in step S305 includes a command for the sound source IC 418, this command is output to the sound source IC 418. In step S307, lamp control processing is performed based on the processing result of step S305. For example, if the performance data read in step S305 includes a command for the various lamps 420, this command is output to the drive circuit 422.

[0139] In step S308, shutter control processing is performed based on the processing result of step S3005. For example, if the performance data read out in step S305 contains a command for the shutter 163, this command is output to the drive circuit 424. In step S309, information output processing is performed to set up sending a command to the second sub-control unit 500 based on the processing result of step S305. For example, if the performance data read out in step S305 contains a command to be sent to the second sub-control unit 500, settings are made to output this control command, and the process returns to step S302.

[0140] Next, the command reception interrupt processing of the first sub-control unit 400 will be explained using Figure 8 (b). This command reception interrupt processing is processing executed by the first sub-control unit 400 when it detects a strobe signal output by the main control unit 300. In step S401 of the command reception interrupt processing, the command output by the main control unit 300 is stored as an unprocessed command in a command memory area provided in RAM 408.

[0141] Next, using Figure 8 (c), we will explain the first sub-control unit timer interrupt processing executed by the CPU 404 of the first sub-control unit 400. The first sub-control unit 400 is equipped with a hardware timer that generates a timer interrupt at a predetermined period (once every 2 ms in this embodiment), and executes timer interrupt processing at a predetermined period in response to this timer interrupt.

[0142] In step S501, 1 is added to the value of the timer variable storage area of ​​RAM 408 described in step S302 in the first sub-control unit main processing shown in Figure 8 (a) and stored in the original timer variable storage area. Therefore, in step S302, the timer variable value is determined to be 10 or greater every 20 ms (2 ms x 10). In step S502, commands are sent to the second sub-control unit 500 set in step S309, and the random number value for performance is updated, etc.

[0143] <Processing of the second sub-control unit> Next, the processing of the second sub-control unit 500 will be explained using Figure 9. Figure 9(a) is a flowchart of the main processing executed by the CPU 504 of the second sub-control unit 500. Figure 9(b) is a flowchart of the command reception interrupt processing of the second sub-control unit 500. Figure 9(c) is a flowchart of the timer interrupt processing of the second sub-control unit 500. Figure 9(d) is a flowchart of the image control processing of the second sub-control unit 500.

[0144] First, in step S601 in Fig. 9(a), various initial settings are performed. When the power is turned on, an initialization process is first executed in step S601. In this initialization process, input / output port initial settings, initialization process of the storage area in the RAM 508, initialization process of the storage area in the VRAM 536, etc. are performed.

[0145] In step S602, it is determined whether the timer variable is 10 or greater, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or greater, the process proceeds to step S603. In step S4003, 0 is assigned to the timer variable. In step S604, command processing is performed. In command processing, the CPU 504 of the second sub-control unit 500 determines whether a command has been received from the CPU 404 of the first sub-control unit 400.

[0146] In step S605, a performance control process is performed. Specifically, if a new command is received in step S604, a process corresponding to this command is performed. For example, a process is executed to read performance data for performing image control related to the background image from ROM 506. In addition, a process is executed to read other performance data from ROM 506, and if the performance data needs to be updated, a process to update the performance data is performed.

[0147] In step S606, image control processing (described in detail later) is performed based on the processing result of step S605. For example, if there is an image control command in the performance data read in step S605, image control corresponding to this command is performed. For example, image control related to the display image (notification image, background image) is executed. When this image control processing is completed, the process returns to step S602.

[0148] Next, the command reception interrupt processing of the second sub-control unit 500 will be explained using Figure 9 (b). This command reception interrupt processing is processing that the second sub-control unit 500 executes when it detects a strobe signal output by the first sub-control unit 400.

[0149] In step S701 of the command reception interrupt processing, the command output by the first sub-control unit 400 is stored in a command memory area provided in the RAM 508 as an unprocessed command.

[0150] Next, using Figure 9 (c), we will explain the second sub-control unit timer interrupt processing executed by the CPU 504 of the second sub-control unit 500. The second sub-control unit 500 is equipped with a hardware timer that generates a timer interrupt at a predetermined period (once every 2 ms in this embodiment), and executes timer interrupt processing at a predetermined period in response to this timer interrupt.

[0151] In step S801, 1 is added to the value in the timer variable storage area of ​​RAM 508 described in step S602 in the second sub-control unit main processing shown in Figure 9 (a), and the result is stored in the original timer variable storage area. Therefore, in step S602, the timer variable value is determined to be 10 or greater every 20 ms (2 ms x 10). In step S802, update processing of the random number value for performance, etc. is performed.

[0152] Next, the image control processing of step S606 in the main processing of the second sub-control unit 500 will be described with reference to Fig. 9(d). This figure is a diagram showing a flowchart illustrating the flow of the image control processing.

[0153] In step S901, an instruction to transfer image data is given. Here, the CPU 504 first swaps the designation of the drawing area between the display area A and the display area B of the VRAM 536. As a result, one frame of image stored in the display area not designated as the drawing area is displayed on the performance image display device 157. Next, the CPU 504 sets the ROM coordinates (the transfer source address of the ROM 506), the VRAM coordinates (the transfer destination address of the VRAM 536), and the like in the attribute register of the VDP 534 based on the position information table, and then sets a command to instruct the start of transfer of image data from the ROM 506 to the VRAM 536. The VDP 534 transfers the image data from the ROM 506 to the VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

[0154] In step S902, it is determined whether or not a transfer end interrupt signal has been input from the VDP 534. If a transfer end interrupt signal has been input, the process proceeds to step S903; if not, the process waits for the transfer end interrupt signal to be input.

[0155] In step S903, parameters are set based on the production scenario configuration table and attribute data, etc. Here, CPU 504 instructs VDP 534 on information of image data constituting the display image (coordinate axes of VRAM 536, image size, VRAM coordinates (layout coordinates), transparency, etc.) in order to form a display image in display area A or B of VRAM 536 based on the image data transferred to VRAM 536 in step S901. VDP 534 sets parameters according to the attributes based on the command stored in the attribute register.

[0156] In step S904, a drawing instruction is issued. In this drawing instruction, the CPU 504 instructs the VDP 534 to start drawing an image. The VDP 534 starts drawing an image in the frame buffer in accordance with the instruction from the CPU 504.

[0157] In step S905, it is determined whether or not a generation end interrupt signal has been input from VDP 534 based on the end of image drawing. If a generation end interrupt signal has been input, proceed to step S906; if not, wait for the generation end interrupt signal to be input.

[0158] In step S906, a scene display counter, which is set in a predetermined area of ​​the RAM 508 and counts how many scene images have been generated, is incremented (+1), and the process ends.

[0159] <Speaker mounting structure> Next, the mounting structure of the speaker in the slot machine 100 will be described.

[0160] FIG. 10 is a front view showing the slot machine 100 with the front door 102 open. The main body 101 is a box body surrounded by an upper panel 261, a left side panel 260, a right side panel 260, a lower panel 264, and a rear panel 242, and opens to the front. Inside the main body 101, a main control board storage case 210 storing a main control board therein is disposed at a position not overlapping with a ventilation hole 249 provided at the top of the rear panel 242, and three reels 110 to 112 are disposed below the main control board storage case 210. To the side of the main control board storage case 210 and the reels 110 to 112, i.e., on the left side panel 260 as viewed from the front, a sub-control board storage case 220 storing a sub-control board therein is disposed. Also, on the right side panel 260, an external centralized terminal board 248 is attached which is connected to the main control board and outputs information about the slot machine 100 to an external device.

[0161] A medal payout device 180 (a device for paying out medals accumulated in a bucket) is disposed on the lower panel 264, and a power supply device 252 having a power supply board is disposed above the medal payout device 180, i.e., below the reels 110 to 112, and a power switch 244 is disposed on the front side of the power supply device 252. The power supply device 252 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 a predetermined part (e.g., the RAM 308 of the main control unit 300, etc.) for a predetermined period (e.g., 10 days) even after the power supply from the outside is cut off.

[0162] An auxiliary medal storage 240 is provided to the right of the medal payout device 180, and an overflow terminal is provided behind this (not shown). The power supply device 252 is provided with a power cord connector for connecting a power cord 264, and the power cord 264 connected to this connector extends to the outside through a power cord hole 262 opened in a back panel 242 of the main body 101.

[0163] The front door 102 is hinged to the left side panel 260 of the main body 101 via a hinge device 276, and above the pattern display window 113 are provided the performance device 160, a performance control board (not shown) that controls this performance device 160, and an upper speaker 272. Below the pattern display window 113 are provided a medal selector 170 for selecting inserted medals, and a passage 266 through which medals pass when the medal selector 170 drops illegal medals, etc. into the medal tray 161. Furthermore, a speaker unit 600 is provided at a position corresponding to the sound hole 181.

[0164] <Speaker mounting structure / speaker unit configuration> Next, the configuration of the speaker unit 600 will be described with reference to Fig. 11. Fig. 11 is an exploded perspective view of the speaker unit 600.

[0165] As explained using Figure 10, speaker unit 600 is screwed to the lower left side of the back surface of front door 102, and as shown in Figure 11, it is composed of a speaker 610 (first component) for outputting low frequencies with a large diaphragm, and a back cover 620 (second component) that covers the back side of speaker 610, and is attached to a speaker pedestal 630 (base) formed on the back surface of front door 102.

[0166] <Speaker mounting structure / speaker base> The speaker base 630 (base) comprises an outer frame 631 formed to match the roughly rectangular outer shape of the flange 614 of the speaker 610, mounting sleeves 632 formed at each of the four inner corners of the outer frame 631 for screwing the speaker 610 and rear cover 620 to the front door 102, and a circular inner frame 633 against which the front peripheral edge of the frame 612 of the speaker 610 abuts.

[0167] A sound hole 161 consisting of multiple holes is formed on the inside of the inner frame portion 633 of the speaker base 630, and the low-pitched sound output from the speaker 610 is output to the outside of the slot machine 100 through this sound hole 161.

[0168] <Speaker mounting structure / speaker, rear cover> Next, the speaker 610 and the rear cover 620 that constitute the speaker unit 600 will be described in detail with reference to FIGS.

[0169] Fig. 12(a) is a side view of rear cover 620, and Fig. 12(b) is a top view of rear cover 620. Fig. 12(c) is a side view of speaker 610, and Fig. 12(d) is a top view of speaker 610. Fig. 13(a) is a top view of speaker unit 600, and Fig. 13(b) is a cross-sectional view along line AA of speaker unit 600 shown in Fig. 13(a).

[0170] <Speaker mounting structure / Speaker> Speaker 610 (first member) is a cone-type dynamic speaker, and as shown in Figures 12(c) and 13(b), is roughly composed of an electromagnetic circuit 611 consisting of a voice coil and a magnet and vibrating a diaphragm 613 (described later) in response to an electric signal, a frame 612 that supports the electromagnetic circuit 611, the diaphragm 613 that vibrates to generate sound, and a flange 614 to which this diaphragm 613 is fixed so that it can vibrate.

[0171] Frame 612 is a cylindrical metal ring frame that widens slightly toward the front, and has a plurality of openings 615 (see FIG. 11) formed in the circumferential direction on the side for releasing air around diaphragm 613. That is, a plurality of openings 615 are formed in the circumferential direction on the side of frame 612, and supports 612a are formed in the front-rear direction between openings 615. Diaphragm 613 is formed in a cone shape that opens toward the front, using a flexible material such as paper, for example.

[0172] 12(d), dedicated screw holes 616a (first through holes) for screwing the speaker 610 to the front door 102 are formed in the upper left corner and the lower right corner of the flange 614. Also, common screw holes 616b (second through holes) for screwing the speaker 610 and the rear cover 620 to the front door 102 are formed in the lower left corner and the upper right corner of the flange 614.

[0173] In this example, two dedicated screw holes 616a (first through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the upper left and lower right corners on the outer edge of the flange 614, and two common screw holes 616b (second through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners on the outer edge of the flange 614. As a result, the dedicated screw holes 616a (first through holes) and the common screw holes 616b (second through holes) are arranged alternately at a predetermined interval around the circumference of the flange 614.

[0174] According to this example, when the speaker 610 (first member) is fixed to the front door 102 (base) using the dedicated screw hole 616a (first through hole) for positioning, or when only the rear cover 620 (second member) is removed from the front door 102 (base), the speaker 610 (first member) can be stably fixed, thereby improving safety and workability.

[0175] The positions and numbers of the "first through hole" and the "second through hole" according to the present invention are not limited to this example, and for example, one dedicated screw hole 616a (first through hole) may be arranged only at either the upper left corner or the lower right corner on the outer edge of the flange 614, and one common screw hole 616b (second through hole) may be arranged only at either the lower left corner or the upper right corner on the outer edge of the flange 614. Also, three or more dedicated screw holes 616a (first through holes) may be arranged on the outer edge of the flange 614, and three or more common screw holes 616b (second through holes) may be arranged on the outer edge of the flange 614, and the number of dedicated screw holes 616a (first through holes) and common screw holes 616b (second through holes) may not be the same.

[0176] The flange 614 also functions as a member that supports the diaphragm 613 so that it can vibrate, and an outer edge 613a (see FIG. 13(b)) of the diaphragm 613, which passes through an opening in the flange 614 and appears on the rear side of the flange 614, is fixed to the rear side of the flange 614. The thickness of the flange 614 is designed to be greater than the maximum vibration amplitude of the diaphragm 613 so as not to inhibit the vibration of the diaphragm 613.

[0177] In this example, rear cover 620 is placed on the rear of speaker 610, and when rear cover 620 is fixed to speaker base portion 630 of front door 102, the minimum distance between rear cover 620 and front door 102 is also designed to be longer than the thickness of flange 614 so as not to impede the vibration of diaphragm 613.

[0178] <Speaker mounting structure / rear cover> Rear cover 620 (second member) is a resin member that houses most of speaker 610 inside. In detail, rear cover 620 has circular opening 621 formed on the rear side for exposing the rear end of speaker 610 (part of electromagnetic circuit 611), and is provided with stepped cylindrical side wall portion 622 that widens slightly toward the front.

[0179] 12(b), rear cover 620 has two protruding pieces 623a and two protruding pieces 623b with screw holes, which protrude circumferentially outward from one front end of side wall portion 622. Screw holes 624 (third through holes) are formed in protruding pieces 623b with screw holes, which are arranged diagonally at the lower left corner and upper right corner (vertices at the ends of the diagonal line), for integrating speaker 610 and rear cover 620 and screwing them to front door 102.

[0180] With this configuration, the shared screw hole 616b (second through hole) in the flange 614 of the speaker 610 and the screw hole 624 (third through hole) in the screw hole-equipped protruding piece 623b of the rear cover 620 are aligned with the holes in the mounting sleeve 632 of the speaker pedestal portion 630 (base) and fastened with a screw (fixing means), whereby the speaker unit 600 is integrated and fixed to the rear surface of the front door 102. The method of mounting the speaker unit 600 will be described later.

[0181] In addition, the protruding pieces 623a arranged diagonally (at the vertices of the ends of the diagonal line) at the upper left and lower right corners of the rear cover 620 have a thicker shape than the protruding piece 623b with a screw hole, as shown in the side view of Figure 12(a), and on its inside is formed a screw head accommodating space 623a1 capable of accommodating the head (screw head) of a screw (fixing means).

[0182] With this configuration, by aligning the dedicated screw hole 616a (first through hole) in the flange 614 of the speaker 610 with the hole in the mounting sleeve 632 of the speaker pedestal portion 630 (base) and fastening with a screw (fixing means), even if the rear cover 620 is positioned relative to the rear surface of the speaker 610 after only the speaker 610 is fixed to the rear surface of the front door 102, the rear cover 620 can be attached to the rear surface of the speaker 610 without the protruding piece 623a of the rear cover 620 interfering with the screw (fixing means) attached to the dedicated screw hole 616a of the speaker 610.

[0183] In addition, the rear cover 620 (second member) has a point-symmetric shape and can be attached to the speaker base 630 (base) even when rotated 180 degrees, which makes it possible to facilitate the installation work of the rear cover 620 (second member).

[0184] A box-shaped space 622S is formed protruding from a part of side wall 622 for storing lead wires connected to electromagnetic circuit 611 and leading the lead wires to the outside of speaker unit 600. Side wall 622 is also formed with a plurality of ventilation holes 625, which are openings for releasing air around diaphragm 613, at predetermined intervals in the circumferential direction.

[0185] <Speaker installation structure / correct installation method> Next, a correct method for mounting the speaker unit 600 will be described with reference to FIG.

[0186] FIG. 14(a) is a diagram showing a schematic example of a correct mounting method for the speaker unit 600. As shown in FIG.

[0187] When attaching the speaker unit 600 to the speaker base 630 (base), first, as shown in FIG. 14(a-1), the speaker 610 (first member) is attached to the speaker base 630 (base), and then, as shown in FIG. 14(a-2), the rear cover 620 (second member) is attached to the speaker base 630 (base).

[0188] More specifically, as shown in FIG. 14(a-1), two dedicated screw holes 616a (first through holes) in a flange 614 of the speaker 610 are aligned with holes in a mounting sleeve 632 of a speaker pedestal portion 630 (base) and fastened with screws 634 (fixing means), thereby attaching only the speaker 610 to the speaker pedestal portion 630 (base).

[0189] Next, rear cover 620 is positioned relative to speaker base 630 (base) so that it covers the rear surface of speaker 610. Since a screw head accommodating space 623a1 is formed in protruding piece 623a of rear cover 620 and rear cover 620 does not interfere with screws 634 (fixing means) attached to dedicated screw holes 616a (first through holes) of speaker 610, rear cover 620 can be reliably positioned on the rear surface of speaker 610 as shown in FIG. 14(a-2).

[0190] Finally, with the rear cover 620 positioned on the rear of the speaker 610, the screw holes 624 (third through holes) in the screw hole protruding piece 623b of the rear cover 620 are aligned with the two shared screw holes 616b (second through holes) in the flange 614 of the speaker 610 and the holes in the mounting sleeve 632 of the speaker base part 630 (base), and the rear cover 620 is attached to the speaker base part 630 (base) by fastening with the screws 634 (fixing means). As a result, the speaker unit 600 is integrated and fixed to the rear surface of the front door 102.

[0191] According to this example, when the speaker 610 (first member) and the rear cover 620 (second member) are fixed to the speaker base 630 (base) with a screw (fixing means), they can be fixed at once with one screw 634 (fixing means) through the common screw hole 616b (second through hole) of the speaker 610 (first member) and the screw hole 624 (third through hole) of the rear cover 620 (second member), so that the attachment work of the members can be simplified compared to the conventional method. Also, the speaker 610 (first member) can be fixed to the base and positioned using the dedicated screw hole 616a (first through hole), and then the rear cover 620 (second member) can be fixed to the speaker base 630 (base), so that it is not necessary to position the two members at the same time, and the work efficiency can be improved.

[0192] Furthermore, when the speaker unit 600 is correctly attached, as shown in FIG. 14(a-2), the dedicated screw hole 616a (first through hole) in the speaker 610 (first member) is covered by the protruding piece 623a of the rear cover 620 (second member), so it can be visually confirmed that there is no need to use the dedicated screw hole 616a (first through hole) when fixing the rear cover 620 (second member), and the attachment work of the members can be performed reliably.

[0193] In addition, the rear cover 620 (second member) has a point-symmetric shape and can be attached to the speaker base 630 (base) even when rotated 180 degrees, which makes it possible to facilitate the installation work of the rear cover 620 (second member).

[0194] <Speaker installation structure / incorrect installation method> Next, an incorrect installation method for the speaker unit 600 will be described with reference to FIG.

[0195] FIG. 14(b) is a diagram showing a schematic example of an incorrect installation method of the speaker unit 600.

[0196] The example shown in FIG. 14(b-1) shows an example in which the two shared screw holes 616b (second through holes) in the flange 614 of the speaker 610 are mistakenly aligned with the holes in the mounting sleeve 632 of the speaker pedestal portion 630 (base) instead of the two dedicated screw holes 616a (first through holes) and fastened with screws 634 (fixing means), thereby attaching only the speaker 610 to the speaker pedestal portion 630 (base).

[0197] In this example, as shown in FIG. 14(b-2), when rear cover 620 is positioned relative to speaker base 630 (base) so as to cover the rear surface of speaker 610, the bottom of protruding piece 623b with screw hole of rear cover 620 interferes with screw 634 (fixing means) that has been erroneously attached to shared screw hole 616b (second through hole) of speaker 610, and therefore rear cover 620 cannot be positioned on the rear surface of speaker 610 and rear cover 620 cannot be attached.

[0198] According to this example, it is possible to easily recognize that the mounting method of the speaker 610 (first member) is incorrect, and it is possible to prevent operational mistakes before they occur.

[0199] 15(a) and 15(b) are diagrams showing another example of an incorrect mounting method of the speaker unit 600. In FIG.

[0200] The example shown in FIG. 15(a) is an example in which the speaker 610 (first member) and the rear cover 620 (second member) are attached in the wrong order, with the rear cover 620 (second member) being attached to the speaker base 630 (base) first.

[0201] Since the speaker 610 (first member) cannot be accommodated in the rear cover 620 (second member) when it is attached to the speaker base 630 (base), it is easy to recognize that the installation method of the speaker 610 (first member) is incorrect, and work errors can be prevented in advance.

[0202] The example shown in FIG. 15(b) is an example in which the rear cover 620 (second member) is mistakenly rotated 90 degrees and an attempt is made to position it relative to the speaker pedestal portion 630 (base).

[0203] The rear cover 620 (second member) has a point-symmetric shape and can be attached to the speaker base 630 (base) even when rotated 180 degrees, but since it does not have an axisymmetric shape, it cannot be positioned relative to the speaker base 630 (base) when rotated 90 degrees.

[0204] Furthermore, since the position of box-shaped space 622S of rear cover 620 is shifted by 90 degrees, speaker 610 cannot be housed in rear cover 620. Therefore, it is easy to recognize that the method of attaching rear cover 620 (second member) is incorrect, and work errors can be prevented in advance.

[0205] <Speaker installation structure / 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 including a first member (for example, the speaker 610 shown in FIG. 11 or 14) that can be fixed to a base (for example, the speaker base portion 630 of the front door 102 shown in FIG. 11) and a second member (for example, the rear cover 620 shown in FIG. 11 or 14) that can cover at least a part of the first member, and the first member has a plurality of through holes for fixing the first member to the base, and the plurality of through holes are one or a plurality of first through holes (for example, 12(d)) and one or more second through holes different from the first through hole (for example, shared screw hole 616b shown in FIG. 12(d)), the second member has one or more through holes (hereinafter referred to as "third through holes"; for example, screw hole 624 shown in FIG. 11 and FIG. 14) for fixing the second member to the base, the first member is fixed to the base using the first through hole, and the second member is fixed to the base using the third through hole and the second through hole.

[0206] According to the game machine of this embodiment, when the first member and the second member are fixed to the base by the fixing means, they can be fixed at once by one fixing means via the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art. Also, since it is possible to fix the second member to the base while the first member is fixed and positioned to the base using the first through hole, it is not necessary to position the two members at the same time, and the work efficiency can be improved.

[0207] It should be noted that the "first member" and "second member" according to the present invention are not limited to a speaker and a rear cover, and may be, for example, a board and a board case, a connector and a connector cover, a movable body and a movable body cover, etc. In other words, the "first member" according to the present invention may be any "member that can be fixed to a base", and the "second member" according to the present invention may be any "member that can cover at least a part of the first member".

[0208] In addition, when the first member is fixed to the base using the first through hole, and then the second member is fixed to the base using the third through hole and the second through hole, the first through hole in the first member may be covered by the second member.

[0209] With this configuration, it is possible to visually confirm that there is no need to use the first through hole when fixing the second member, and the member mounting operation can be carried out reliably.

[0210] Moreover, the first member may have a plurality of the first through holes and the second through holes, and the plurality of first through holes and the plurality of second through holes may be arranged alternately in the outer circumferential direction of the first member.

[0211] With this configuration, when the first member is fixed to the base using the first through hole for positioning, or when only the second member is removed from the base, the first member can be stably fixed, thereby improving safety and workability.

[0212] In addition, the multiple first through holes and the multiple second through holes may be arranged alternately in the outer circumferential direction of the first member, and the multiple first through holes may be located in diagonal positions on the first member, and the multiple second through holes may be located in diagonal positions on the first member.

[0213] In addition, when the first member is fixed to the base with a fixing means (e.g., screw 634 shown in FIG. 14(b)) via the second through hole and then the second member is positioned to be fixed to the base, the third through hole of the second member may interfere with the fixing means.

[0214] With this configuration, it is possible to easily recognize that the first member has been attached in an incorrect manner, and thus to prevent operational errors from occurring.

[0215] Moreover, the gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 610 shown in FIG. 11 or 14) that can be fixed to a base (for example, the speaker base portion 630 of the front door 102 shown in FIG. 11) and a second member (for example, the rear cover 620 shown in FIG. 11 or 14) that can cover at least a part of the first member, the first member includes a plurality of first through holes and a plurality of second through holes different from the first through holes, the second member includes a plurality of third through holes, the first through hole is a through hole used when the first member of the first member and the second member is fixed to the base, the second through hole and the third through hole are through holes used when both the first member and the second member are fixed to the base, and the plurality of first through holes and the plurality of second through holes are alternately arranged on the outer periphery of the first member.

[0216] Furthermore, a gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (e.g., the speaker 610 shown in FIG. 11 or 14) that can be fixed to a base (e.g., the speaker base portion 630 of the front door 102 shown in FIG. 11) and a second member (e.g., the rear cover 620 shown in FIG. 11 or 14) that can cover at least a part of the first member, the first member including a plurality of first through holes and a plurality of second through holes different from the first through holes, the second member including a plurality of third through holes, and the first through holes being fixed to the first member and the second member. the first through hole is a through hole used when fixing the first member to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the multiple first through holes and the multiple second through holes are arranged alternately on the outer periphery of the first member, and a rectangle is formed when straight lines are connected between the multiple first through holes and the second through holes on either side of the multiple first through holes, and the multiple first through holes are arranged on the diagonal of the rectangle (the vertices at the ends of the diagonal).

[0217] In addition, the gaming machine according to the present embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 610 shown in FIG. 11 or 14) that can be fixed to a base (for example, the speaker base portion 630 of the front door 102 shown in FIG. 11) and a second member (for example, the rear cover 620 shown in FIG. 11 or 14) that can cover at least a part of the first member, the first member having a plurality of first through holes and a plurality of second through holes different from the first through holes, and the second member having a plurality of third through holes. a first through hole which is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole which are through holes used when fixing both the first member and the second member to the base, the plurality of first through holes and the plurality of second through holes which are alternately arranged on the outer periphery of the first member, and the base has a frame portion formed to match the outer shape of the first member.

[0218] According to the game machine of this embodiment, when the first member and the second member are fixed to the base by the fixing means, they can be fixed at once by one fixing means via the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art. Also, since it is possible to fix the second member to the base while the first member is fixed and positioned to the base using the first through hole, it is not necessary to position the two members at the same time, and the work efficiency can be improved.

[0219] <Speaker mounting structure (variation 1) / speaker unit configuration> Next, the configuration of a speaker unit 700 according to the first modification will be described with reference to Fig. 16. Fig. 16 is an exploded perspective view of the speaker unit 700 according to the first modification.

[0220] As shown in FIG. 16, the speaker unit 700 of the first modified example is composed of a speaker 710 (first member) for outputting low-pitched sounds having a large diaphragm, and a rear cover 720 (second member) that covers the rear side of the speaker 710, and is attached to a speaker pedestal portion 730 (base) formed on the rear surface of the front door 102 of the slot machine.

[0221] <Speaker mounting structure / speaker base> The speaker pedestal 730 (base) is configured to include an annular frame support 731 that supports the frame 714 of the speaker 710, a cylindrical cover support 735 that supports the bottom of the rear cover 720, four mounting sleeves 732 for screwing the speaker 710 and the rear cover 720 to the front door 102, and a disk-shaped sound hole plate 734 attached to the inside of the frame support 731. The detailed configuration of the speaker pedestal 730 (base) will be described later with reference to FIG.

[0222] <Speaker mounting structure (variation 1) / speaker, rear cover> Next, speaker 710 and rear cover 720 constituting speaker unit 700 according to the first modification will be described in detail with reference to FIGS.

[0223] Fig. 17(a) is a side view of rear cover 720, and Fig. 17(b) is a top view of rear cover 720. Fig. 17(c) is a side view of speaker 710, and Fig. 17(d) is a top view of speaker 710. Fig. 18(a) is a top view of speaker unit 700, and Fig. 18(b) is a cross-sectional view along line BB of speaker unit 700 shown in Fig. 18(a).

[0224] <Speaker mounting structure (variation 1) / Speaker> The speaker 710 (first component) is a cone-type dynamic speaker, and as shown in Figures 17(c) and 18(b), is generally composed of an electromagnetic circuit 711 (electrical component) consisting of a voice coil and a magnet and vibrating a diaphragm 713 (described later) in response to an electric signal, a frame 712 that supports the electromagnetic circuit 711, the diaphragm 713 that vibrates to generate sound, a flange 714 to which the diaphragm 713 is fixed so that it can vibrate, a pair of lead terminals 716 arranged on the right and left sides, respectively, of the flange 714 when viewed from above, and a lead wire (wiring) 717 detachably connected to the lead terminal 716.

[0225] Frame 712 is a cylindrical metal ring frame that widens slightly toward the front, and has a plurality of openings 715 (see FIG. 16) formed in the circumferential direction on the side surface for allowing air around diaphragm 713 to escape. That is, a plurality of openings 715 are formed in the circumferential direction on the side surface of frame 712, and supports 712a (see FIG. 16) are formed in the front-rear direction between openings 715. Diaphragm 713 is formed in a cone shape that opens toward the front, using a flexible material such as paper, for example.

[0226] 17(d), dedicated screw holes 716a (first through holes) for screwing the speaker 710 to the speaker pedestal portion 730 (base) are formed in the upper left corner and the lower right corner of the outer end of the flange 714. Also, shared screw holes 716b (second through holes) for screwing the speaker 710 and the rear cover 720 to the speaker pedestal portion 730 (base) are formed in the lower left corner and the upper right corner of the outer end of the flange 714.

[0227] In this example, two dedicated screw holes 716a (first through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the upper left and lower right corners on the outer edge of the flange 714, and two shared screw holes 716b (second through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners on the outer edge of the flange 714. As a result, the dedicated screw holes 716a (first through holes) and the shared screw holes 716b (second through holes) are arranged alternately at a predetermined interval circumferentially along the outer edge of the flange 714.

[0228] In other words, as shown in FIG. 17(d), when a plurality of dedicated screw holes 716a (first through holes) and the shared screw holes 716b (second through holes) on either side of these plurality of dedicated screw holes 716a (first through holes) are connected by an imaginary straight line VL, a virtual rectangle VQ is formed, and the plurality of dedicated screw holes 716a (first through holes) are arranged on the diagonal of the imaginary rectangle VQ (the vertices at the ends of the diagonal), and the plurality of shared screw holes 716b (second through holes) are arranged on the diagonal of the imaginary rectangle VQ (the vertices at the ends of the diagonal).

[0229] Furthermore, when attention is paid to the distance between the dedicated screw hole 716a (first through hole) and the shared screw hole 716b (second through hole), as shown in FIG. 17(d), the shortest distance L1 from the dedicated screw hole 716a (first through hole) located in the upper left corner to one of the shared screw holes 716b (second through hole) (for example, the shared screw hole 716b located in the upper right corner) and the shortest distance L2 from the dedicated screw hole 716a (first through hole) located in the upper left corner to a through hole other than the one of the second through holes of the shared screw holes 716b (second through hole) (for example, the shared screw hole 716b located in the lower left corner) are substantially the same.

[0230] According to this example, when the speaker 710 (first member) is fixed to the speaker pedestal portion 730 (base) of the front door 102 using the dedicated screw hole 716a (first through hole) for positioning, or when only the rear cover 720 (second member) is removed from the speaker pedestal portion 730 (base), the speaker 710 (first member) can be stably fixed, thereby improving safety and workability.

[0231] <Speaker mounting structure (variation 1) / rear cover> Next, the rear cover 720 (second member) will be described in detail.

[0232] The rear cover 720 (second member) is a colored transparent resin member capable of housing the speaker 710 (first member) inside, and is made of a material that allows the speaker 710 (first member) to be visible from the outside when the speaker 710 (first member) is housed inside.

[0233] According to this example, at least a portion of the speaker 710 (first member) can be seen through the rear cover 720 (second member), and therefore the fixed position of the speaker 710 (first member) relative to the speaker pedestal 730 (base) and the positional relationship between the speaker 710 (first member) and the rear cover 720 (second member) can be visually confirmed, thereby improving convenience in the installation work of the members.

[0234] In addition, the rear cover 720 (second member) may be any member having transparency, and its material is not limited to colored transparent resin, but may be, for example, colorless transparent (or translucent) plastic, acrylic, polycarbonate, polyvinyl chloride, glass, metal, etc.

[0235] As shown in Figures 17(a) and (b), rear cover 720 has a circular cover portion 721 formed on the rear side that covers the rear end of speaker 710, and has a cylindrical side wall portion 722 that widens slightly toward the rear from this cover portion 721 as its base end.

[0236] Cover portion 721 has a plurality of rectangular ventilation holes 725 formed therein as openings for releasing air around electromagnetic circuit 711 of speaker 710, and has predetermined markings 726 (in this example, a part number and material) on the upper side as viewed from above. The display form of predetermined markings 726 is not particularly limited, but in this example, a part number marking (in this example, a character string "SPxxxx") indicating the part number of rear cover 720 and a material marking (in this example, a character string "PC") indicating the material of rear cover 720 are engraved on the surface of cover portion 721.

[0237] According to this example, a predetermined marking 726 is provided on the rear cover 720, so that the correct orientation (installation direction) of the rear cover 720 can be easily identified by the orientation of this predetermined marking 726, thereby improving convenience when installing the rear cover 720, etc.

[0238] As shown in FIG. 17(b), the rear cover 720 is provided with two protruding pieces 723a and two protruding pieces 723b with screw holes, which protrude outward from the outer edge of the side wall portion 722.

[0239] In this example, two protrusion pieces 723a are arranged diagonally (at the vertices of the ends of the diagonal) at the upper left and lower right corners on the outer edge of side wall portion 722, and two protrusion pieces 723b with screw holes are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners on the outer edge of side wall portion 722, so that the protrusion pieces 723a and the protrusion pieces 723b with screw holes are arranged alternately at a predetermined interval in the circumferential direction along the outer edge of side wall portion 722.

[0240] In other words, as shown in FIG. 17(b), when the vertices of the multiple protrusion pieces 723a and the protrusion pieces with screw holes 723b on either side of the multiple protrusion pieces 723a are connected by an imaginary straight line VL2, a virtual rectangle VQ2 is formed, and the multiple protrusion pieces 723a are arranged on the diagonals of the virtual rectangle VQ2 (the vertices at the ends of the diagonals), and the multiple protrusion pieces with screw holes 723b are arranged on the diagonals of the virtual rectangle VQ2 (the vertices at the ends of the diagonals).

[0241] Screw holes 724 (third through holes) for integrating the speaker 710 and rear cover 720 and screwing them to the speaker base 730 (base) are formed in the protruding pieces 723b with screw holes, which are located diagonally between the lower left and upper right corners (the vertices of the ends of the diagonal), at positions slightly off-center toward the cover part 721 (towards the center of the rear cover 720) rather than the center of the protruding pieces 723b with screw holes.

[0242] With this configuration, the speaker unit 700 is integrated and fixed to the speaker base 730 (base) by fastening the common screw hole 716b (second through hole) of the speaker 710 and the screw hole 724 (third through hole) of the rear cover 720 to the speaker base 730 (base) with a screw 740 (fixing means; see FIG. 16). The method of mounting the speaker unit 700 will be described later.

[0243] Around the screw hole 724 (third through hole) in the screw hole protruding piece 723b, a thin screw hole identification recess 724a consisting of an annular recess having an outer diameter larger than that of the screw hole 724 is formed. Due to the screw hole identification recess 724a formed around the screw hole 724, the thickness around the screw hole 724 (third through hole) of the rear cover 720 is made thinner than the thickness of other parts of the rear cover 720.

[0244] According to this example, when the rear cover 720 (second member) is positioned, the fixing position (screw hole 724 (third through hole)) of the rear cover 720 (second member) can be easily recognized due to the presence of the protruding piece 723b with the screw hole, and the protruding piece 723b with the screw hole can also function as reinforcement for the portion (screw hole identification recess 724a) around the screw hole 724 (third through hole) where the thickness is formed thin.

[0245] Further, the side wall portion 722 is formed with a screw hole identification groove 722a which is a linear groove extending from the lower portion to the upper portion of the side wall portion 722 and communicates with the screw hole identification recess portion 724a.

[0246] That is, in this example, a screw hole identification recess 724a and a screw hole identification groove 722a are formed around the screw hole 724 (third through hole), making it possible to identify the screw hole 724 (third through hole).

[0247] According to this example, at least one of the dedicated screw hole 716a (first through hole), the shared screw hole 716b (second through hole), and the screw hole 724 (third through hole) (in this example, the screw hole 724 (third through hole)) is configured to be identifiable, so that it is possible to easily determine whether each through hole is a through hole used when fixing only the first member to the base, or a through hole used when fixing both the first member and the second member to the base, thereby improving the efficiency of the member attachment work. In addition, the correct orientation (attachment direction) of the rear cover 720 can be easily identified using the through hole type as a clue, thereby improving convenience when attaching the rear cover 720, etc.

[0248] In this example, as a configuration for making screw hole 724 (third through hole) identifiable, a screw hole identification recess 724a and a screw hole identification groove 722a are formed near screw hole 724 (third through hole). However, the present invention is not limited to this. For example, only one of screw hole identification recess 724a and screw hole identification groove 722a may be formed, or a sticker or the like that can identify screw hole 724 (third through hole) may be attached near screw hole 724 (third through hole), or a marking, printing, engraving, etc. that can identify screw hole 724 (third through hole) may be applied.

[0249] Furthermore, a portion that allows the screw hole 724 (third through hole) to be identified may be formed in a member (for example, the speaker base 730 (base) or the speaker 710 (first member)) other than the rear cover 720 (second member), a sticker or the like that allows the screw hole 724 (third through hole) to be identified may be affixed, or a marking, printing, engraving, or the like that allows the screw hole 724 (third through hole) to be identified may be applied.

[0250] Also, a configuration has been exemplified in which the screw hole 724 (third through hole) of the rear cover 720 can be identified, but instead of (or in addition to) this, a configuration may be adopted in which the dedicated screw hole 716a (first through hole) and / or the shared screw hole 716b (second through hole) of the speaker 710 (first member) can be identified.

[0251] Therefore, for example, a portion that allows at least one of the dedicated screw hole 716a (first through hole), the shared screw hole 716b (second through hole), and the screw hole 724 (third through hole) to be identified may be formed in the mounting sleeve 732 of the speaker base 730 (base), a sticker or the like that allows at least one of the through holes to be identified may be attached, or a marking, printing, engraving, or the like that allows at least one of the through holes to be identified may be applied, or the front of the speaker 710 (first member) may be provided. The lunge 714 may be provided with a portion that allows the dedicated screw hole 716a (first through hole) and / or the shared screw hole 716b (second through hole) to be identified, or a sticker or the like that allows the dedicated screw hole 716a (first through hole) and / or the shared screw hole 716b (second through hole) to be identified may be attached, or the dedicated screw hole 716a (first through hole) and / or the shared screw hole 716b (second through hole) may be marked, printed, engraved, or the like that allows the dedicated screw hole 716a (first through hole) and / or the shared screw hole 716b (second through hole) to be identified.

[0252] Furthermore, by making the shape of the protruding piece 723b with a screw hole of the rear cover 720 different from the shape of the protruding piece 723a, it may be possible to make it distinguishable that the through hole formed in the protruding piece 723b with a screw hole is the through hole used when fixing both the speaker 710 (first member) and the rear cover 720 (second member) to the speaker base part 730 (base), or conversely, by making the shape of the protruding piece 723a of the rear cover 720 different from the shape of the protruding piece 723b with a screw hole, it may be made distinguishable that the through hole of the speaker 710 covered by the protruding piece 723a is the through hole used when fixing only the speaker 710 (first member) to the speaker base part 730 (base).

[0253] With this configuration, it becomes possible to visually identify the function of the through-hole based on the shape of the protruding piece of the rear cover 720, thereby improving work efficiency.

[0254] 17(a), protruding pieces 723a arranged diagonally between the upper left and lower right corners of rear cover 720 (the vertices of the ends of the diagonal line) are thick, two-stepped portions that are higher from the bottom surface of rear cover 720 than protruding piece 723b with a screw hole. A screw accommodating space 723a1 large enough to accommodate a part (head) of screw 740 is formed inside protruding piece 723a.

[0255] With this configuration, by fastening dedicated screw hole 716a (first through hole) of speaker 710 to speaker base portion 730 (base) with screw 740, even if rear cover 720 is positioned relative to the rear surface of speaker 710 after only speaker 710 is fixed to speaker base portion 730, the head of screw 740 attached to dedicated screw hole 716a of speaker 710 is accommodated in screw accommodating space 723a1, so that screw 740 does not interfere with rear cover 720 and rear cover 720 can be securely attached to the rear surface of speaker 710.

[0256] In addition, the rear cover 720 (second member) has a point-symmetric shape and can be attached to the speaker base 730 (base) even when rotated 180 degrees, which makes it possible to facilitate the installation work of the rear cover 720 (second member).

[0257] As described above, rear cover 720 is provided with predetermined markings 726, and therefore, when attaching rear cover 720 to speaker base 730, it is preferable to attach it in the correct orientation, with the side with the predetermined markings 726 facing up, so that the predetermined markings 726 can be easily seen; however, even if rear cover 720 is rotated 180 degrees from the correct orientation, the direction of the predetermined markings 726 will be reversed, but it will still be possible to attach it to speaker base 730 (base).

[0258] As shown in FIG. 17(b), a box-shaped space 722S (space portion) is protrudingly formed on the right and left outer edges of the rear cover 720 when viewed from above, for accommodating a pair of lead terminals 716 and leading the lead wires 717 to the outside of the speaker unit 700.

[0259] As shown in Figures 17(a) and (b), this box-shaped space 722S (space) is composed of a first space 722S1 in the shape of a vertically elongated rectangular parallelepiped that extends from the upper part of the side wall portion 722 as a base end to near the lower part of the side wall portion 722, and a second space 722S2 in the shape of a horizontally elongated rectangular parallelepiped that is connected to this first space 722S1 and has a width slightly larger than that of the first space 722S1, and the first space 722S1 and the second space 722S2 are positioned radially outward of the rear cover 720 (second member) than the screw hole 724 (third through hole).

[0260] With this configuration, when the speaker 710 (first member) and the rear cover 720 (second member) are fixed to the speaker base 730 (base), a space is formed between the speaker 710 (first member) and the rear cover 720 (second member), and as shown in FIG. 18(b), the lead wires 717 (wiring) of the speaker 710 can be pulled out to the outside of the speaker 710 (first member) and the rear cover 720 (second member) through this space.

[0261] According to this example, even if a portion of the speaker 710 (first component) is covered by the rear cover 720 (second component), the lead wire 717 (wiring) of the speaker 710 (first component) can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0262] Furthermore, when fixing the rear cover 720 (second member) to the speaker base portion 730 (base), the area other than the contact point (around the through hole) between the speaker base portion 730 (base) and the rear cover 720 (second member) can be made wider, thereby preventing the wiring from getting pinched between the speaker base portion 730 (base) and the rear cover 720 (second member).

[0263] In addition, the second space 722S2 having a horizontally elongated rectangular parallelepiped shape makes it possible to secure a large area when pulling out the wiring from between the rear cover 720 (second member) and the speaker base portion 730 (base), and the first space 722S1 having a vertically elongated rectangular parallelepiped shape partially restricts the area for guiding the wiring, allowing the wiring of the speaker 710 to be smoothly guided to the second space 722S2, and preventing the wiring from gathering near the through hole when the rear cover 720 (second member) is fixed, which would interfere with the installation work.

[0264] In this example, two box-shaped spaces (spaces) 722S are formed in the rear cover 720, but the number of box-shaped spaces (spaces) 722S is not limited to this example, and when the speaker 710 has only one lead terminal, only one box-shaped space (space) 722S capable of accommodating this lead terminal may be formed. Also, a notched recess or the like for leading a lead wire to the outside may be formed below the box-shaped space (space) 722S.

[0265] <Speaker mounting structure (variation 1) / speaker base> Next, the speaker pedestal 730 (base) will be described in detail with reference to FIG.

[0266] 19(a) to (d) are diagrams showing an example of a method for attaching the speaker unit 700 in chronological order, and FIG. 19(a) is a diagram showing the speaker base part 730 with the sound hole plate 734 removed.

[0267] As explained using Figure 16, the speaker base 730 (base) is composed of a circular frame support part 731 that supports the frame 714 of the speaker 710, a cylindrical cover support part 735 that supports the bottom of the rear cover 720, four mounting sleeves 732 (732a, 732b) for screwing the speaker 710 and rear cover 720 to the front door 102, and a circular sound hole plate 734 that is attached to the inside of the frame support part 731.

[0268] As shown in FIG. 19(a), the sound hole plate 734 has a plurality of circular sound holes 734a for outputting sound from the speaker 710, and four locking portions 734b that can be locked to the sound hole plate locking portion 736 of the frame support portion 731 are formed at a predetermined interval along the circumferential direction on the outer edge of the sound hole plate 734.

[0269] Meanwhile, on the inside of the frame support part 731, four sound hole plate locking parts 736 capable of locking the locking parts 734b of the sound hole plate 734 are formed at predetermined intervals along the inner circumference of the frame support part 731. Also, the height of the frame support part 731 (height from the rear surface of the front door 102) is designed to be higher than the maximum vibration amplitude of the diaphragm 713 so as not to inhibit the vibration of the diaphragm 713 of the speaker 710.

[0270] The sound hole plate 734 has an outer diameter smaller than the inner diameter of the frame support part 731, and after it is fitted inside the frame support part 731, the four locking parts 734b are respectively locked to the four sound hole plate locking parts 736, thereby fixing it to the inside of the frame support part 731 as shown in Figure 19 (b).

[0271] Of the four mounting sleeves 732, the first mounting sleeves 732a, which are located at the upper left corner and the lower right corner when viewed from above, are mounting sleeves to which dedicated screw holes 716a (first through holes) of the speaker 710 are fastened by screws 740, as shown in FIG. 19(c).

[0272] On the other hand, of the four mounting sleeves 732, the second mounting sleeves 732b located at the lower left corner and upper right corner when viewed from above are mounting sleeves in which the shared screw hole 716b (second through hole) of the speaker 710 and the screw hole 724 (third through hole) of the rear cover 720 are fastened by screws 740, as shown in FIG. 19(d).

[0273] A first rectangular boss 737a having a rectangular shape is provided on the outer side of the frame support part 731 so as to surround the periphery of the first mounting sleeve 732a, and a second rectangular boss 737b having a rectangular shape is provided on the outer side of the frame support part 731 so as to surround the periphery of the second mounting sleeve 732b. In addition, arc-shaped through-hole identification bosses 738 are provided on the outer side of the first mounting sleeve 732a, which are located at the upper left corner and the lower right corner when viewed from above.

[0274] This through hole identification boss 738 is a boss that is erected to identify that, among the four mounting sleeves 732, the two first mounting sleeves 732a are mounting sleeves to be fastened to the dedicated screw hole 716a (first through hole) of the speaker 710, and is not formed in the vicinity of the second mounting sleeve 732b.

[0275] According to this example, a through hole identification boss 738 is provided adjacent to the first mounting sleeves 732a of the two of the four mounting sleeves 732. Using this through hole identification boss 738 as a guide, it is possible to attach the speaker 710 and rear cover 720 to the speaker base portion 730 in the correct orientation, thereby preventing operational errors and improving work efficiency.

[0276] Furthermore, arc-shaped mounting direction identification bosses 739 are provided between the first rectangular boss 737a, located at the upper left corner when viewed from above, and the second rectangular boss 737b, located at the lower left corner when viewed from above, and between the second rectangular boss 737b, located at the upper right corner when viewed from above, and the first rectangular boss 737a, located at the lower right corner when viewed from above.

[0277] This mounting direction identification boss 739 is a boss that is erected to make the mounting direction of the speaker 710 and the rear cover 720 easy to identify, and is not formed between the first rectangular boss 737a, which is located in the upper left corner when viewed from above, and the second rectangular boss 737b, which is located in the upper right corner when viewed from above, and between the second rectangular boss 737b, which is located in the lower left corner when viewed from above, and the first rectangular boss 737a, which is located in the lower right corner when viewed from above.

[0278] According to this example, mounting direction identification boss 739 is provided, which allows the mounting direction of speaker 710 and rear cover 720 to be identified. Therefore, when mounting speaker 710 to speaker base portion 730, the position of lead terminal 716 of speaker 710 is aligned with mounting direction identification boss 739, making it possible to mount speaker 710 on speaker base portion 730 in the correct orientation. When mounting rear cover 720 to speaker base portion 730, the box-shaped space 722S of rear cover 720 is aligned with mounting direction identification boss 739, making it possible to mount rear cover 720 on speaker base portion 730 in the correct orientation. This makes it possible to prevent work errors when mounting speaker 710 and rear cover 720 and to improve work efficiency.

[0279] <Speaker mounting structure (variation 1) / mounting method> Next, a method for mounting the speaker unit 700 will be described with reference to FIG.

[0280] When attaching the speaker unit 700 to the speaker base 730, first, the speaker 710 is attached to the speaker base 730 as shown in Figures 19(b) and (c), and then the rear cover 720 is attached to the speaker base 730 as shown in the same figures (c) and (d).

[0281] More specifically, when attaching speaker 710 to speaker base 730, the dedicated screw hole 716a of speaker 710 is aligned with first mounting sleeve 732a using through-hole identification boss 738 and first rectangular boss 737a of speaker base 730 as landmarks, and the position of lead terminal 716 of speaker 710 is aligned with mounting direction identification boss 739, thereby positioning speaker 710 relative to speaker base 730.

[0282] Next, as shown in FIG. 19(c), the two dedicated screw holes 716a of the speaker 710 are aligned with the holes in the mounting sleeve 732a of the speaker base 730 and fastened with screws 740, thereby attaching only the speaker 710 to the speaker base 730.

[0283] Since speaker 710 has a shape that is nearly point-symmetrical, and can be attached to speaker base 730 even when rotated 180 degrees, the attachment work of speaker 710 can be facilitated.

[0284] Furthermore, because the lead terminal 716 and lead wire 717 of the speaker 710 are configured to be detachable, even when the wiring of the lead wire 717 up to the speaker base 730 is complete, it is possible to rotate the speaker 710 180 degrees and attach it to the speaker base 730 and connect the lead terminal 716 and lead wire 717 later, and even when the speaker 710 is attached to the speaker base 730, it is possible to change the wiring of the lead wire 717 and connect the lead terminal 716 and lead wire 717 later.

[0285] Next, when attaching rear cover 720 to speaker base portion 730, screw holes 724 of rear cover 720 are recognized using screw hole identification recesses 724a and screw hole identification grooves 722a as landmarks, and then aligned with second mounting sleeve 732b using second rectangular boss 737b of speaker base portion 730 as a landmark. At the same time, the position of box-shaped space 722S of rear cover 720 is aligned with mounting direction identification boss 739 while covering the rear surface of speaker 710 with rear cover 720, thereby positioning rear cover 720 relative to speaker base portion 730.

[0286] 19(d), the screw holes 724 of the rear cover 720 are aligned with the shared screw holes 716b of the speaker 710 and the holes of the mounting sleeve 732b of the speaker base 730, and the rear cover 720 is attached to the speaker base 730 by fastening with screws 740. As a result, the speaker unit 700 is integrated and fixed to the rear surface of the front door 102.

[0287] According to this example, when fixing speaker 710 and rear cover 720 to speaker base 730 with screw 740, it is possible to fix them at once with one screw 740 via shared screw hole 716b of speaker 710 and screw hole 724 of rear cover 720, so that the work of attaching the members can be simplified compared to the conventional method. Also, it is possible to fix rear cover 720 to speaker base 730 in a state where speaker 710 is fixed to the base and positioned using dedicated screw hole 716a, so that it is not necessary to position two members at the same time, and the work efficiency can be improved.

[0288] Furthermore, rear cover 720 has a shape that is nearly point-symmetric, and even when rotated 180 degrees, it can be attached to speaker base 730 with lead terminals 716 and lead wires 717 of speaker 710 accommodated in box-shaped space 722S, making it possible to facilitate the installation work of rear cover 720.

[0289] Furthermore, when the speaker unit 700 is correctly attached and the speaker 710 (first member) is covered with the rear cover 720 (second member), as shown in FIG. 19(d), the dedicated screw hole 716a (first through hole) in the speaker 710 (first member) is configured to be covered by the protruding piece 723a (a certain portion) of the rear cover 720 (second member). This makes it possible to visually confirm that it is not necessary to use the dedicated screw hole 716a when fixing the rear cover 720, and also makes it possible to easily position the rear cover 720 (second member) relative to the speaker 710 (first member), thereby ensuring the installation work of the second member.

[0290] Furthermore, a screw accommodating space 723a1 (accommodating space) having a predetermined space is formed in the protruding piece 723a (a certain portion) of the rear cover 720 (second member). Therefore, even when the rear cover 720 is positioned relative to the rear surface of the speaker 710, the head of the screw 740 (fixing means) attached to the dedicated screw hole 716a (first through hole) of the speaker 710 (first member) is accommodated in the screw accommodating space 723a1 (space portion). Therefore, the screw 740 (fixing means) does not interfere with the rear cover 720 (second member), and the rear cover 720 (second member) can be securely attached to the rear surface of the speaker 710 (first member).

[0291] In particular, when screws are used as the fixing means, if the screws are not tightly fastened when fixing speaker 710 (first member) to speaker base 730 (base), there is a possibility that the screw head will protrude more than necessary from dedicated screw hole 716a (first through hole); however, because rear cover 720 (second member) is formed with screw accommodating space 723a1 (accommodating space) capable of accommodating at least a part of screw 740 (fixing means), it is possible to avoid the risk of interference between rear cover 720 (second member) and the screw head.

[0292] In addition, the thickness of the area around the screw hole 724 of the rear cover 720 is thinner than the thickness of other parts of the rear cover 720, so that the stroke amount of the screw 740 (fixing means) that fastens both the common screw hole 716b (second through hole) of the speaker 710 (first member) and the screw hole 724 (third through hole) of the rear cover 720 (second member) can be reduced, and the work efficiency can be improved. In addition, a part of the head of the screw 740 (fixing means) can be accommodated in the screw hole identification recess 724a formed around the third through hole, so that the screw 740 (fixing means) is less likely to come off, and the speaker 710 (first member) and the rear cover 720 (second member) can be stably fixed to the speaker base part 730 (base). In addition, the screw hole identification recess 724a (around the third through hole) also functions as a positioning when attaching the screw 740 (fixing means).

[0293] Furthermore, when attaching speaker 710 and rear cover 720, common screws 740 (screws of the same length and thickness) can be used, eliminating the need to use multiple types of screws, improving convenience and eliminating screw installation errors, allowing the components to be attached reliably.

[0294] In addition, in order to use a common screw 740 when attaching the speaker 710 and the rear cover 720, the length of the screw 740 needs to be at least as long as the thickness of the screw hole 724 in the rear cover 720 plus the thickness of the shared screw hole 716b in the speaker 710.

[0295] For this reason, when a common screw 740 is used to fasten the dedicated screw hole 716a of the speaker 710, the length of the screw becomes excessive by the thickness of the rear cover 720; however, in this example, the screw 740 attached to the dedicated screw hole 716a of the speaker 710 is configured to be accommodated in the screw accommodating space 723a1, so that the screw 740 does not interfere with the rear cover 720, and by covering the screw 740 with the screw accommodating space 723a1, deterioration of the screw 740 and tampering with the screw 740 can be prevented.

[0296] 19(d), in a state where the rear cover 720 is attached to the speaker base 730, the bottom of the rear cover 720 is configured to be supported by a cylindrical cover support portion 735 arranged on the right side in a top view in addition to the four mounting sleeves 732. That is, when the speaker 710 (first member) and the rear cover 720 (second member) are fixed to the speaker base 730 (base), a part of the rear cover 720 (second member) abuts against the mounting sleeve 732 and the cover support portion 735 of the speaker base 730 (base), and a space is formed between the speaker base 730 (base) and the rear cover 720 (second member).

[0297] Also, as described using FIG. 18(b), even when the speaker 710 (first member) is covered with the rear cover 720 (second member), a space is formed between the speaker 710 (first member) and the rear cover 720 (second member).

[0298] With this configuration, spaces are formed between the speaker base 730 (base) and the rear cover 720 (second member), and between the speaker 710 (first member) and the rear cover 720 (second member), and the lead wires 717 (wiring) of the speaker 710 can be pulled out to the outside of the speaker 710 (first member) and the rear cover 720 (second member) through these spaces.

[0299] <Speaker mounting structure (variation 1) / 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 including a first member (for example, the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (for example, the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (for example, the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, the first member including a first through hole (for example, the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (for example, the shared screw hole 716b shown in FIG. 17(d)), the second member including a plurality of third through holes (for example, the screw hole 724 shown in FIG. 17(b)), and the second member including a plurality of third through holes (for example, the screw hole 724 shown in FIG. 17(b)). The gaming table is characterized in that: a first through hole is a through hole used when fixing the first member of the first and second members to the base; the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base; the first through hole and the plurality of second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole; a convex portion (e.g., a protruding piece 723b with a screw hole shown in Figure 17(b)) is formed near the third through hole in the second member; and a concave portion (e.g., a screw hole identification groove 722a shown in Figure 17(b)) is formed in the convex portion near the third through hole.

[0300] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, a convex portion is formed near the third through hole in the second member, and a concave portion is formed near the third through hole (i.e., the third through hole is provided with an identification means by which it can be identified), so that it is easy to determine whether each through hole is a through hole used when fixing to the base, or a through hole used when fixing both the first member and the second member to the base, thereby improving the efficiency of the member installation work.

[0301] Additionally, each of the plurality of second through holes may be provided at an outer end portion of the second member.

[0302] With this configuration, the second member can be stably fixed to the base.

[0303] Furthermore, the base may be formed with a portion that allows the first member to be positioned (for example, a first mounting sleeve 732a, a second mounting sleeve 732b, and a frame support portion 731 shown in FIG. 19(b)).

[0304] With this configuration, even if the second member is detached from the base, the first member can be stably fixed to the base.

[0305] In addition, the shortest distance from the first through hole to one of the plurality of second through holes (for example, the shortest distance L1 shown in FIG. 17(d)) ​​and the shortest distance from the first through hole to another through hole of the plurality of second through holes other than the one through hole (for example, the shortest distance L2 shown in FIG. 17(d)) ​​may be approximately the same.

[0306] With this configuration, the first member can be stably fixed to the base, thereby improving safety and workability.

[0307] Here, "almost the same" is not limited to the case where the shortest distance from the first through hole to one of the plurality of second through holes and the shortest distance from the first through hole to another through hole of the plurality of second through holes are "the same," but also includes the case where the two shortest distances are "substantially the same" (for example, when the ratio of the shortest distances is 4:6 or 6:4, and when the first through hole is located approximately in the center between the second through holes located on both sides of it, etc.).

[0308] In addition, the shortest distance between the two may be different depending on the shape, weight, etc. of the first member. For example, the first through hole may be located between the second through holes located on both sides of it, near the center of gravity of the first member. If the first member is polygonal in shape, the second through hole may be located at a position on the first member that is diagonal (the apex at the end of the diagonal), or at a position not on the diagonal of the first member, near the apex angle, along a side, or at a position other than the outer edge.

[0309] The first member may be a member including an electrical component (e.g., electromagnetic circuit 711 shown in FIG. 19(b)) to which wiring (e.g., lead wire 717 shown in FIG. 19(b)) is connected, and may be configured such that a space is formed between the first member and the second member when the first member and the second member are fixed to the base, and such that the wiring can be drawn out to the outside of the first member and the second member through the space.

[0310] With this configuration, even if a portion of the first member is covered with the second member, the wiring of the first member can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0311] Further, a gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (for example, the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (for example, the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, in which the first member includes a first through hole (for example, the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (for example, the shared screw hole 716b shown in FIG. 17(d)), and the second member includes a plurality of third through holes (for example, the screw hole 724 shown in FIG. 17(b)). 17(b) ), the first through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are alternately arranged on the outer periphery of the first member, a convex portion (e.g., a screw hole protruding piece 723b shown in FIG. 17(b) ) is formed near the third through hole in the second member, and the convex portion has a concave portion (e.g., a screw hole identification groove 722a shown in FIG. 17(b) ) formed near the third through hole.

[0312] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, a convex portion is formed near the third through hole in the second member, and a concave portion is formed in the convex portion near the third through hole (i.e., the third through hole is provided with an identifiable identification means), so that it is easy to distinguish whether the through hole is the one used when fixing to the base, or the one used when fixing both the first member and the second member to the base, thereby improving the efficiency of the member installation work.

[0313] Furthermore, a gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (e.g., the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (e.g., the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (e.g., the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, in which the first member includes a first through hole (e.g., the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (e.g., the shared screw hole 716b shown in FIG. 17(d)), the second member includes a plurality of third through holes (e.g., the screw hole 724 shown in FIG. 17(b)), and the first member includes a second through hole (e.g., the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)). the through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, and are configured such that when the first member and the second member are fixed to the base, the first through hole of the first member is covered by a certain portion of the second member (for example, a protruding piece 723a of a rear cover 720 shown in Figure 19(d)).

[0314] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. Furthermore, since the first through hole of the first member is configured to be covered by a certain portion of the second member when the first member and the second member are fixed to the base, it is possible to visually confirm that there is no need to use the first through hole when fixing the second member, and the positioning of the second member relative to the first member can be easily performed, ensuring reliable installation of the second member.

[0315] In addition, the first member and the second member are configured to be fixable (or to be fixed) to the base by a fixing means (e.g., a screw 740 shown in Figures 16 and 19), and an accommodation space (e.g., a screw accommodation space 723a1 shown in Figure 17(a)) capable of accommodating at least a portion of the fixing means may be formed in the certain portion.

[0316] With this configuration, a part of the fixing means attached to the first through hole of the first member is accommodated in the accommodation space, so the fixing means does not interfere with the second member, and the second member can be reliably attached to the back surface of the first member. In particular, when a screw is used as the fixing means, if the screw is not tightly fastened when the first member is fixed to the base, the head of the screw may protrude more than necessary from the first through hole, but since the second member has an accommodation space capable of accommodating at least a part of the fixing means, the risk of interference between the second member and the head of the screw can be avoided.

[0317] Furthermore, after the first through hole of the first member is fixed to the base by the fixing means, the third through hole of the second member may be positioned relative to the second through hole of the first member, and the second through hole of the first member and the third through hole of the second member may be configured to be fixable (or to be fixed) to the base by the fixing means.

[0318] With this configuration, for example, if a screw is used as the fixing means, if the screw is not tightly tightened when fixing the first member to the base, there is a possibility that the screw head will protrude more than necessary from the first through hole. However, since an accommodation space capable of accommodating at least a part of the fixing means is formed in the second member, it is possible to avoid the risk of interference between the second member and the screw head.

[0319] The second member may be made of a material that allows the first member to be visually recognized from the outside in a state in which the first member is housed inside the second member.

[0320] With this configuration, the first member can be seen through the second member, making it possible to check the fixed position of the first member relative to the base and the positional relationship between the first member and the second member, etc., thereby improving convenience when installing the members.

[0321] Furthermore, a gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (e.g., the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (e.g., the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (e.g., the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, in which the first member includes a first through hole (e.g., the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (e.g., the shared screw hole 716b shown in FIG. 17(d)), and the second member includes a plurality of third through holes (e.g., the screw hole 19(d) )。 The first through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are alternately arranged on the outer periphery of the first member, and the first through hole of the first member is covered by a certain portion of the second member (for example, a protruding piece 723a of a rear cover 720 shown in FIG. 19(d)) when the first member and the second member are fixed to the base.

[0322] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state where the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members at the same time, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are alternately arranged on the outer periphery of the first member, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, since the first member and the second member are configured to be covered by a certain part of the second member when the first member and the second member are fixed to the base, it can be visually confirmed that it is not necessary to use the first through hole when fixing the second member, and the positioning of the second member relative to the first member can be easily performed, and the installation work of the second member can be performed reliably.

[0323] Furthermore, a gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (e.g., the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (e.g., the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (e.g., the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, in which the first member includes a first through hole (e.g., the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (e.g., the shared screw hole 716b shown in FIG. 17(d)). The second member includes a plurality of third through holes (e.g., the dedicated screw hole 716a shown in FIG. 17(b)). the first through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, and a portion where the third through hole is formed is configured as a thin-walled portion that is thinner than the surrounding area of ​​the portion (for example, a screw hole identification recess 724a shown in FIGS. 17(a) and (b)).

[0324] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, since the area where the third through hole is formed is a thin-walled area that is thinner than the surrounding area, the stroke amount of the fixing means (e.g., a screw) that fastens both the second through hole of the first member and the third through hole of the second member can be reduced, improving work efficiency, and since a part of the head of the fixing means can be accommodated in the thin-walled area around the third through hole, the fixing means is less likely to come off, and the first member and the second member can be stably fixed to the base. In addition, the thin-walled area formed around the third through hole also functions as a positioning area when the fixing means is attached.

[0325] The second member may also include a protruding piece (for example, a protruding piece 723b with a screw hole shown in FIG. 17(b)) that protrudes outward from the vicinity of the third through hole.

[0326] With this configuration, when the second member is positioned, the fixed position of the second member (third through hole) can be easily recognized by the presence of the protruding piece, and it can also function as reinforcement for the portion around the third through hole that is formed with a thin thickness.

[0327] In addition, when the first member and the second member are fixed to the base, the first through hole of the first member may be configured to be covered by a certain portion of the second member (for example, the protruding piece 723a of the rear cover 720 shown in Figure 19 (d)).

[0328] With this configuration, it is possible to visually confirm that there is no need to use the first through hole when fixing the second member, and the positioning of the second member relative to the first member can be easily performed, ensuring that the installation work of the second member can be performed reliably.

[0329] In addition, a gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (for example, the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (for example, the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, in which the first member includes a first through hole (for example, the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (for example, the shared screw hole 716b shown in FIG. 17(d)), and the second member includes a plurality of third through holes. the first through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are alternately arranged on the outer periphery of the first member, and the portion where the third through hole is formed is composed of a thin-walled portion that is thinner than the surrounding area of ​​the portion (for example, screw hole identification recess 724a shown in FIGS. 17(a) and (b)).

[0330] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state where the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members at the same time, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are alternately arranged on the outer periphery of the first member, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, since the area where the third through hole is formed is a thin-walled area that is thinner than the surrounding area, the stroke amount of the fixing means (e.g., a screw) that fastens both the second through hole of the first member and the third through hole of the second member can be reduced, improving work efficiency, and since a part of the head of the fixing means can be accommodated in the thin-walled area around the third through hole, the fixing means is less likely to come off, and the first member and the second member can be stably fixed to the base. In addition, the thin-walled area formed around the third through hole also functions as a positioning area when the fixing means is attached.

[0331] In addition, a gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (for example, the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (for example, the back cover 720 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, the first member including a first through hole (for example, the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes (for example, the shared screw hole 716b shown in FIG. 17(d)) ​​different from the first through hole, the second member including a plurality of third through holes (for example, the screw hole 724 shown in FIG. 17(b)), the first through hole including the the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, and are configured such that when the first member and the second member are fixed to the base, a part of the second member abuts against a support portion provided on the base, thereby forming a space (for example, a box-shaped space 722S shown in Figures 17(a) and (b)) between the second member and the base.

[0332] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are arranged on the outer periphery of the first member in the order of the second through hole, the first through hole, and the second through hole, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. Furthermore, when the first member and the second member are fixed to the base, a portion of the second member abuts against a support portion provided on the base, thereby forming a space between the second member and the base. Therefore, even when the first member and the second member are fixed to the base and a portion of the first member is covered by the second member, for example, wiring of the first member can be pulled out to the outside, thereby increasing the freedom of design.

[0333] The first member may be a member including an electrical component (e.g., electromagnetic circuit 711 shown in FIG. 19(b)) to which wiring (e.g., lead wire 717 shown in FIG. 19(b)) is connected, and may be configured so that the wiring can be pulled out to the outside of the first member and the second member through the space.

[0334] With this configuration, even if a portion of the first member is covered with the second member, the wiring of the first member can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0335] In addition, the second member may have a space portion having a predetermined space (e.g., a box-shaped space 722S shown in Figures 17(a) and (b)), the space portion being configured to be able to accommodate at least a portion of the wiring, and the space portion being configured to have a first space portion having a vertically elongated rectangular parallelepiped shape (e.g., a first space portion 722S1 shown in Figures 17(a) and (b)) and a second space portion having a horizontally elongated rectangular parallelepiped shape (e.g., a second space portion 722S2 shown in Figures 17(a) and (b)), and when the first member is covered with the second member, the space portion of the second member may be positioned between the first through hole and the second through hole of the first member.

[0336] With this configuration, when the second member is fixed to the base, a wide area can be secured other than the contact point between the base and the second member (around the through hole), thereby preventing the wiring from becoming pinched between the base and the second member.

[0337] The first space and the second space may be disposed on the second member outside the third through hole (outside in the radial direction of the second member).

[0338] With this configuration, the second space portion in the shape of a horizontally elongated rectangular parallelepiped ensures a large area when pulling out the wiring from between the second member and the base, and the first space portion in the shape of a vertically elongated rectangular parallelepiped partially restricts the area for guiding the wiring, thereby preventing the wiring from gathering near the through hole when the second member is fixed and interfering with the installation work.

[0339] In addition, a gaming machine according to this embodiment (e.g., the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (e.g., the speaker 710 shown in FIG. 16 and FIG. 17(c) and (d)) that can be fixed to a base (e.g., the speaker base part 730 shown in FIG. 16 and FIG. 19) and a second member (e.g., the back cover 620 shown in FIG. 16 and FIG. 17(a) and (b)) that can cover at least a part of the first member, the first member including a first through hole (e.g., the dedicated screw hole 716a shown in FIG. 17(d)) ​​and a plurality of second through holes different from the first through hole (e.g., the shared screw hole 716b shown in FIG. 17(d)), the second member including a plurality of third through holes (e.g., the screw hole 724 shown in FIG. 17(b)), The first through hole is a through hole used when fixing the first member of the first and second members to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the first through hole and the plurality of second through holes are arranged alternately on the outer periphery of the first member, and when the first member and the second member are fixed to the base, a part of the second member abuts against a support portion provided on the base, thereby forming a space between the second member and the base (for example, a box-shaped space 722S shown in Figures 17(a) and (b)).

[0340] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state where the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members at the same time, and the work efficiency can be improved. In addition, since the first through hole and the multiple second through holes are alternately arranged on the outer periphery of the first member, the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. Furthermore, when the first member and the second member are fixed to the base, a portion of the second member abuts against a support portion provided on the base, thereby forming a space between the second member and the base. Therefore, even when the first member and the second member are fixed to the base and a portion of the first member is covered by the second member, for example, wiring of the first member can be pulled out to the outside, thereby increasing the freedom of design.

[0341] <Speaker mounting structure (variation 2) / speaker unit configuration> Next, the configuration of a speaker unit 800 according to Modification 2 will be described with reference to Fig. 20. Fig. 20(a) is an exploded perspective view of the speaker unit 800 according to Modification 2.

[0342] As shown in FIG. 20(a), the speaker unit 800 of the second modification is composed of a low-frequency output speaker 810 (first member) having a large diaphragm and a rear cover 820 (second member) covering the rear side of the speaker 810, and is attached to a speaker pedestal portion 830 (base) formed below the rear surface of the front door 102 of the slot machine.

[0343] In the slot machine (game machine) of this example, two speaker base portions 830 are arranged horizontally on the back surface of the front door 102 at a predetermined interval, and each speaker base portion 830 is configured to allow a speaker unit 800 to be attached.

[0344] FIG. 20(b) is an external perspective view showing two speaker units 800 attached to the rear surface of the front door 102. FIG.

[0345] As shown in Figure 20(b), the lead wires 817 of the two left and right speakers 810 pass through the inner space of the box-shaped space 822S of the rear cover 820, are pulled out from the space formed between the rear cover 820 and the speaker base 830 to the outside, are wired along the rear surface of the front door 102, and are electrically connected to a sound output control means (for example, the sound source IC 418 of the first sub-control unit 400 described using Figure 3, or the second sub-control unit 500) arranged above the front door 102.

[0346] In this example, two speaker units 800 are arranged horizontally on the back surface of the front door 102, but three or more speaker units 800 may be arranged, and the speaker units 800 may be arranged vertically or diagonally on the back surface of the front door 102.

[0347] The speaker unit 800 can be oriented in a direction in which the box-shaped space 822S of the rear cover 820 and the lead terminal 816 of the speaker 810 face upward and the lead wire 817 of the speaker 810 is drawn from above (the direction shown in FIG. 20(b) , hereinafter sometimes referred to as the “upward direction”), as well as in a direction in which the box-shaped space 822S of the rear cover 820 and the lead terminal 816 of the speaker 810 face rightward and the lead wire 817 of the speaker 810 is drawn from the right side (hereinafter sometimes referred to as the “rightward direction”). ), with box-shaped space 822S of rear cover 820 and lead terminal 816 of speaker 810 facing downward, and lead wire 817 of speaker 810 being drawn out from below (hereinafter sometimes referred to as the "downward direction"), or with box-shaped space 822S of rear cover 820 and lead terminal 816 of speaker 810 facing left, and lead wire 817 of speaker 810 being drawn out from the left side (hereinafter sometimes referred to as the "leftward direction").

[0348] According to this example, the speaker unit 800 can be disposed in an upward, rightward, downward, or leftward direction with respect to the speaker base 830, so that the degree of freedom in mounting the speaker unit 800 can be increased.

[0349] For example, in the mounting mode of the speaker unit 800 shown in Fig. 20(b), since both of the two speaker units 800 are mounted facing upward, the lead wires 817 of the two speakers 810 can be pulled out from above and then gathered above the speaker unit 800, improving the efficiency of wiring work and ease of maintenance. This is particularly suitable for gaming machines that can secure space above the speaker unit 800 (for example, medal-less slot machines that do not have a hopper or medal selector above the speaker unit 800, and enclosed gaming machines that do not have a lower tray above the speaker unit 800).

[0350] On the other hand, when applied to a gaming machine in which it is difficult to secure space above the speaker unit 800 (for example, a slot machine in which a hopper, medal selector, etc. are arranged above the speaker unit 800, or a pachinko machine in which a tray, etc. is arranged above the speaker unit 800), if the two speaker units 800 are attached in a direction other than an upward direction, such as a downward direction, a rightward direction, or a leftward direction, the lead wire 817 of the speaker 810 can be routed to avoid other devices arranged above the speaker unit 800, which not only increases the efficiency of the wiring work but also enables the limited space behind the front door 102 to be used effectively.

[0351] Furthermore, by differing the orientation of the two speaker units 800, the direction in which the lead wire 817 of the speaker 810 is pulled out can be made different. For example, the speaker unit 800 disposed on the left side of the front door 102 when viewed from behind is installed facing right, while the speaker unit 800 disposed on the right side of the front door 102 when viewed from behind is installed facing left, so that the lead wire 817 of the speaker 810 can be pulled out from the two speaker units 800 toward the center of the back of the front door 102, improving the efficiency and maintainability of the wiring work.

[0352] In addition, the length of the lead wire 817 of the speaker 810 is not particularly limited as long as it has a length that allows electrical connection from the speaker 810 to a sound output control means (for example, the sound source IC 418 of the first sub-control unit 400 described using Figure 3, or the second sub-control unit 500); however, for example, by making the length the minimum required when the speaker unit 800 is installed in an upward direction, and configuring the lead wire 817 so that it is not long enough to connect to the sound output control means when the speaker unit 800 is installed in a direction other than upward, the installation direction of the speaker unit 800 can be intentionally restricted, and the installation direction of the speaker unit 800 on the gaming machine can be unified.

[0353] <Speaker mounting structure (variation 2) / speaker base> 20(a), speaker pedestal 830 (base) is configured to include an annular diaphragm support 831 that supports an outer edge 813a (see FIG. 22; a portion that supports the outer edge of the cone of diaphragm 813) of diaphragm 813 of speaker 810, four cylindrical mounting sleeves 832 for screwing speaker 810 and rear cover 820 to front door 102, and a horizontally elongated elliptical sound hole plate 834 that is fitted inside diaphragm support 831. The detailed configuration of speaker pedestal 830 (base) will be described later with reference to FIG. 23.

[0354] In addition, within the space formed by the diaphragm support portion 831 and the rear surface of the front door 102, one of a number of cylindrical bosses 835 for fixing a title panel 162 (see Figure 1) attached to the lower front surface of the front door 102 is disposed.

[0355] According to this example, other components unrelated to the speaker unit 800 or the speaker base portion 830 (in this example, the boss 835 for fixing the title panel 162) can be accommodated within the space formed by the diaphragm support portion 831 and the rear surface of the front door 102, so that the limited space behind the front door 102 can be effectively utilized and space saving can be achieved behind the front door 102.

[0356] <Speaker mounting structure (variation 2) / speaker, rear cover> Next, the speaker 810 and the rear cover 820 constituting the speaker unit 800 according to the second modification will be described in detail with reference to FIGS.

[0357] Fig. 21(a) is a side view of rear cover 820, and Fig. 21(b) is a top view of rear cover 820. Fig. 21(c) is a side view of speaker 810, and Fig. 21(d) is a top view of speaker 810. Fig. 22 is a plan view of speaker 810 housed in the inner space of rear cover 820, as viewed from the bottom side of speaker 810.

[0358] <Speaker mounting structure (variation 2) / Speaker> Speaker 810 (first component) is a cone-type dynamic speaker, and as shown in FIG. 21(c), is roughly composed of an electromagnetic circuit 811 (electrical component) consisting of a voice coil and a magnet and vibrating a diaphragm 813 described later in response to an electric signal, a frame 812 supporting this electromagnetic circuit 811, the diaphragm 813 that vibrates to generate sound, a flat flange 814 to which the diaphragm 813 is fixed so that it can vibrate, a lead terminal 816 arranged on the upper side of the flange 814 when viewed from above, and a lead wire 817 (wiring) detachably connected to the lead terminal 816.

[0359] Frame 812 is a cylindrical metal ring frame that widens slightly toward the front, and has a plurality of openings 815 (see FIG. 20) formed in the circumferential direction on the side for releasing air around diaphragm 813. That is, a plurality of openings 815 are formed in the circumferential direction on the side of frame 812, and supports 812a (see FIG. 20) are formed in the front-rear direction between openings 815. Diaphragm 813 is formed in a cone shape that opens toward the front, using a flexible material such as paper, for example.

[0360] 21(d), elliptical dedicated screw holes 816a (first through holes) for screwing speaker 810 to speaker base 830 are formed in the upper left corner and lower right corner of the outer end of flange 814. Also, elliptical shared screw holes 816b (second through holes) for screwing speaker 810 and rear cover 820 to speaker base 830 are formed in the lower left corner and upper right corner of the outer end of flange 814.

[0361] The size and shape of the dedicated screw hole 816a (first through hole) and the shared screw hole 816b (second through hole) are not particularly limited, but in this example, as shown in FIG. 22, the dedicated screw hole 816a (first through hole) and the shared screw hole 816b (second through hole) are configured as holes that are larger than the circular screw hole 824 (third through hole) of the rear cover 820 and smaller than the circular through hole 825 (fourth through hole) of the rear cover 820.

[0362] In this example, two dedicated screw holes 816a (first through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the upper left and lower right corners on the outer edge of the flange 814, and two common screw holes 816b (second through holes) are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners on the outer edge of the flange 814. As a result, the dedicated screw holes 816a (first through holes) and the common screw holes 816b (second through holes) are arranged alternately at a predetermined interval circumferentially along the outer edge of the flange 818.

[0363] In other words, as shown in FIG. 21(d), when a plurality of dedicated screw holes 816a (first through holes) and the common screw holes 816b (second through holes) on either side of these plurality of dedicated screw holes 816a (first through holes) are connected by a virtual straight line VL, a virtual rectangle VQ is formed, and the plurality of dedicated screw holes 816a (first through holes) are arranged on a (first) diagonal (the vertices at the ends of the diagonal) of the virtual rectangle VQ, and the plurality of common screw holes 816b (second through holes) are arranged on a (second) diagonal (the vertices at the ends of the diagonal) of the virtual rectangle VQ.

[0364] Furthermore, when focusing on the distance between the dedicated screw hole 816a (first through hole) and the shared screw hole 816b (second through hole), as shown in FIG. 21(d), the shortest distance L3 from the dedicated screw hole 816a (first through hole) located in the upper left corner to one of the two shared screw holes 816b (second through holes) (for example, the shared screw hole 816b located in the upper right corner) and the shortest distance L4 from the dedicated screw hole 816a (first through hole) located in the upper left corner to a through hole other than the one of the second through holes of the two shared screw holes 816b (second through holes) (for example, the shared screw hole 816b located in the lower left corner) are substantially the same.

[0365] According to this example, when the speaker 810 (first member) is fixed to the speaker pedestal part 830 (base) using the dedicated screw hole 816a (first through hole) for positioning, or when only the rear cover 820 (second member) is removed from the speaker pedestal part 830 (base), the speaker 810 (first member) can be stably fixed, thereby improving safety and workability.

[0366] As described above, speaker unit 800 can be arranged in an upward, right, downward, or left direction relative to speaker base 830, and lead terminal 816 of speaker 810 can be arranged facing upward, right, downward, or left, thereby increasing the freedom in mounting speaker 810.

[0367] <Speaker mounting structure (variation 2) / rear cover> Next, the rear cover 820 (second member) will be described.

[0368] Rear cover 820 (second component) is a colored transparent resin component capable of housing speaker 810 inside, and is made of a material that allows speaker 810 (first component) to be visible from the outside when speaker 810 (first component) is housed inside.

[0369] According to this example, at least a portion of speaker 810 (first member) can be seen through rear cover 820 (second member), and therefore it is possible to confirm the fixed position of speaker 810 (first member) relative to speaker base 830 (base) and the positional relationship between speaker 810 (first member) and rear cover 820 (second member), thereby improving convenience in the installation work of the members.

[0370] In addition, rear cover 820 may be any transparent material, and its material is not limited to colored transparent resin, but may be, for example, colorless transparent (or translucent) plastic, acrylic, polycarbonate, polyvinyl chloride, glass, metal, etc.

[0371] As shown in Figures 21(a) and (b), rear cover 820 has a circular ring-shaped cover portion 821 formed on the rear side that covers part of the rear end of speaker 810, and has a cylindrical side wall portion 822 that widens slightly toward the rear, with this cover portion 821 as its base end.

[0372] A predetermined marking 826 (in this example, a part number and material) is provided on the upper side of the cover portion 821 when viewed from above. The display form of the predetermined marking 826 is not particularly limited, but in this example, a part number marking (in this example, a character string "SPxxxx") indicating the part number of the rear cover 820 is engraved on the surface of the cover portion 821 to the left of a portion where the lead terminals 816 of the speaker 810 are visible when the rear cover 820 is covered by the speaker 810, and a material marking (in this example, a character string "PC") indicating the material of the rear cover 820 is engraved on the right of a portion where the lead terminals 816 of the speaker 810 are visible when the rear cover 820 is covered by the speaker 810.

[0373] That is, when the speaker 810 is viewed through the rear cover 820, a part number indication (in this example, the character string "SPxxxx") is visible to the left of the lead terminal 816 of the speaker 810, and a material indication (in this example, the character string "PC") is visible to the right of the lead terminal 816 of the speaker 810.

[0374] According to this example, in addition to the predetermined markings 826 being provided on rear cover 820, when speaker 810 is viewed through rear cover 820, lead terminals 816 of speaker 810 are visible. Therefore, the correct orientation (installation direction) of rear cover 820 can be easily identified depending on the orientation of predetermined markings 826 or whether lead terminals 816 of speaker 810 are visible in the center of predetermined markings 826, thereby improving convenience when installing rear cover 820, etc.

[0375] As shown in FIG. 21(b), the rear cover 820 is provided with two protruding pieces 823a and two protruding pieces 823b with screw holes, which protrude outward from the outer edge of the side wall portion 822.

[0376] In this example, two protrusion pieces 823a are arranged diagonally (at the vertices of the ends of the diagonal) at the upper left and lower right corners on the outer edge of side wall portion 822, and two protrusion pieces 823b with screw holes are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners on the outer edge of side wall portion 822, so that the protrusion pieces 823a and the protrusion pieces 823b with screw holes are arranged alternately at a predetermined interval in the circumferential direction along the outer edge of side wall portion 822.

[0377] In other words, as shown in FIG. 21(b), when the vertices of the multiple protrusions 823a and the protrusions with screw holes 823b on either side of the multiple protrusions 823a are connected by a virtual straight line VL2, a virtual rectangle VQ2 is formed, and the multiple protrusions 823a are arranged on a (first) diagonal (the vertices at the ends of the diagonal) of the virtual rectangle VQ2, and the multiple protrusions with screw holes 823b are arranged on a (second) diagonal (different from the first diagonal) of the virtual rectangle VQ2 (the vertices at the ends of the diagonal).

[0378] The protruding pieces 823b with screw holes, which are located diagonally between the lower left and upper right corners (the vertices of the ends of the diagonal), have circular screw holes 824 (third through holes) formed therein for screwing the speaker 810 and rear cover 820 together to the speaker base 730.

[0379] With this configuration, by fastening the common screw hole 816b (second through hole) of the speaker 810 and the screw hole 824 (third through hole) of the rear cover 820 to the speaker pedestal part 830 (base) with a screw 840 (fixing means; see FIG. 20), the speaker unit 800 is integrated and fixed to the speaker pedestal part 730. The method of mounting the speaker unit 800 will be described later.

[0380] Further, near the screw hole 824 in the side wall portion 822, a screw hole identification groove 822a consisting of a linear groove extending from the bottom to the top of the side wall portion 822 is formed. That is, in this example, by forming the screw hole identification groove 822a near the screw hole 824, the screw hole 824 is configured to be identifiable.

[0381] According to this example, at least one of the dedicated screw hole 816a (first through hole), the shared screw hole 816b (second through hole), and the screw hole 824 (third through hole) (in this example, the screw hole 824 (third through hole)) is configured to be identifiable, so that it is possible to easily determine whether each through hole is a through hole used when fixing only the speaker 810 (first member) to the speaker base part 830 (base) or a through hole used when fixing both the speaker 810 (first member) and the rear cover 820 (second member) to the speaker base part 830 (base), thereby improving the efficiency of the installation work of the members. In addition, the correct orientation (installation direction) of the rear cover 820 can be easily identified using the screw hole identification groove 822a as a clue, thereby improving the convenience when installing the rear cover 820, etc.

[0382] In this example, as a configuration for making screw hole 824 (third through hole) identifiable, screw hole identification groove 822a is formed near screw hole 824 (third through hole). However, the present invention is not limited to this. For example, a portion for making screw hole 824 (third through hole) identifiable may be formed in a member (for example, speaker base 830 (base) or speaker 810 (first member)) other than rear cover 820 (second member), a sticker or the like for making screw hole 824 (third through hole) identifiable may be affixed, or a marking, printing, engraving, or the like for making screw hole 824 (third through hole) identifiable may be applied.

[0383] Also, a configuration has been exemplified in which the screw hole 824 (third through hole) of the rear cover 820 can be identified, but instead of (or in addition to) this, a configuration may be adopted in which the dedicated screw hole 816a (first through hole) and / or the shared screw hole 816b (second through hole) of the speaker 810 (first component) can be identified.

[0384] Therefore, for example, a portion that allows at least one of the dedicated screw hole 816a (first through hole), the common screw hole 816b (second through hole), and the screw hole 84 (third through hole) to be identified may be formed in the mounting sleeve 832 of the speaker base part 830 (base), a sticker or the like that allows at least one of the through holes to be identified may be attached, or a marking, printing, engraving, or the like that allows at least one of the through holes to be identified may be applied, or the flag of the speaker 810 (first member) may be provided. The holder 814 may be provided with a portion that allows the dedicated screw hole 816a (first through hole) and / or the common screw hole 816b (second through hole) to be identified, or a sticker or the like that allows the dedicated screw hole 816a (first through hole) and / or the common screw hole 816b (second through hole) to be identified may be attached, or the dedicated screw hole 816a (first through hole) and / or the common screw hole 816b (second through hole) may be marked, printed, engraved, or the like that allows the dedicated screw hole 816a (first through hole) and / or the common screw hole 816b (second through hole) to be identified.

[0385] Furthermore, by making the shape of protruding piece 823b with a screw hole of rear cover 820 different from the shape of protruding piece 823a, it may be possible to make it distinguishable that the through hole formed in protruding piece 823b with a screw hole is a through hole used when fixing both speaker 810 (first member) and rear cover 820 (second member) to speaker base part 830 (base), or conversely, by making the shape of protruding piece 823a of rear cover 820 different from the shape of protruding piece 823b with a screw hole, it may be possible to make it distinguishable that the through hole in speaker 810 corresponding to protruding piece 823a is a through hole used when fixing only speaker 810 (first member) to speaker base part 830 (base).

[0386] With this configuration, it becomes possible to visually identify the function of the through-hole based on the shape of the protruding piece of the rear cover 820, thereby improving work efficiency.

[0387] Also, as shown in FIG. 21(b), a through hole 825 (fourth through hole) having an inner diameter larger than the inner diameter of the screw hole 824 (third through hole) is formed in the protruding pieces 823a arranged diagonally at the upper left corner and the lower right corner of the rear cover 820.

[0388] This through hole 825 (fourth through hole) has an inner diameter larger than that of the elliptical shared screw hole 816b (second through hole) of the speaker 810, as shown in FIG. 22, and also has an inner diameter larger than the outer diameter of the head of the screw 840, as shown in FIG. 23(d).

[0389] With this configuration, by fastening the dedicated screw hole 816a (first through hole) of the speaker 810 to the speaker base portion 830 (base) with a screw 840, even if only the speaker 810 is fixed to the back surface of the front door 102 and then the rear cover 820 is positioned relative to the rear surface of the speaker 810, the screw 840 attached to the dedicated screw hole 816a of the speaker 810 can be accommodated without coming into contact with the through hole 825 and the screw 840 does not interfere with the rear cover 820. Therefore, it is possible to easily visually confirm that the rear cover 820 is attached in the correct position relative to the speaker 810 based on the positional relationship between the through hole 825 (fourth through hole) and the screw 840, and the positioning of the rear cover 820 relative to the speaker 810 can be accurately performed.

[0390] Furthermore, when rear cover 820 is accurately positioned relative to speaker 810, screws 840 are housed inside through holes 825 and horizontal movement of rear cover 820 is restricted by screws 840, thereby preventing rear cover 820 from shifting or rattling when attaching rear cover 820. Furthermore, through holes 825 (fourth through holes) have a larger inner diameter than elliptical shared screw holes 816b (second through holes) of speaker 810, so that an assembly error (shift of rear cover 820) relative to speaker 810 can be absorbed, simplifying the attachment work.

[0391] In this example, a through hole is formed in the protruding piece 823a of the rear cover 820, but the present invention is not limited to this, and for example, instead of a through hole, a portion such as a recess or a notch that does not interfere with the screw 840 may be formed in the protruding piece 823a, or the protruding piece 823a itself may be removed from the rear cover 820. In other words, when the speaker 810 is fixed to the rear surface of the front door 102 with the screw 840, it is sufficient to configure so that the screw 840 attached to the dedicated screw hole 816a of the speaker 810 does not interfere with the rear cover 820.

[0392] As shown in FIG. 21(b), a box-shaped space 822S (space portion) is protrudingly formed on the upper outer edge of the rear cover 820 when viewed from above, for storing the lead terminals 816 of the speaker 810 and leading the lead wires 817 to the outside of the speaker unit 800.

[0393] With this configuration, as shown in FIG. 22, when the speaker 810 (first component) is housed inside the rear cover 820 (second component), a space SP is formed between the speaker 810 (first component) and the rear cover 820 (second component), and the lead wire 817 (wiring) of the speaker 810 can be pulled out to the outside of the speaker 810 (first component) and the rear cover 820 (second component) through the space SP.

[0394] According to this example, even if a portion of the speaker 810 (first component) is covered by the rear cover 820 (second component), the lead wire 817 (wiring) of the speaker 810 (first component) can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0395] As shown in FIG. 22 , four ribs 827 that can come into contact with four flange corners 814a of flange 814 of speaker 810 are formed on the inside of the bottom surface of rear cover 820, and the shape of lower edge 820a of rear cover 820 is molded into a curved shape that is approximately the same as the outer edge of one side of flange 814 of speaker 810.

[0396] According to this example, the four ribs 827 of the rear cover 820 are brought into contact with any of the four flange corners 814a of the flange 814 of the speaker 810, and the lower edge 820a of the rear cover 820 is brought into contact with the outer edge of one side of the flange 814 of the speaker 810, thereby making it possible to easily and reliably position the speaker 810 relative to the rear cover 820 and to integrate the speaker 810 and the rear cover 820. Therefore, by using the installation method 2 described later, the speaker 810 and the rear cover 820 can be attached to the speaker base 830 in an integrated state, and the installation work of the speaker unit 800 can be simplified.

[0397] As described above, the speaker unit 800 can be arranged in an upward, right, downward, or left direction relative to the speaker base 830, and the box-shaped space 822S of the rear cover 820 can be arranged facing upward, right, downward, or left, thereby increasing the freedom in terms of attachment of the rear cover 820.

[0398] As described above, rear cover 820 is provided with predetermined markings 826, and therefore, when attaching rear cover 820 to speaker base 830, it is preferable to attach it in an upward direction so that the side with the predetermined markings 826 is on top and the predetermined markings 826 are easily visible; however, even if rear cover 820 is attached facing right, downward, or left, the direction of the predetermined markings 826 will be upside down, but it will still be possible to attach it to speaker base 830.

[0399] <Speaker mounting structure (variation 2) / speaker base> Next, the speaker pedestal 830 (base) will be described in detail with reference to FIG.

[0400] 23(a) to (d) are diagrams showing an example of a method for attaching the speaker unit 800 in chronological order, with FIG. 23(a) showing the speaker base part 830 with the sound hole plate 834 removed.

[0401] As explained using Figure 20(a), speaker base 830 (base) is composed of a circular diaphragm support part 831 that supports outer edge 813a (see Figure 22; the part that supports the outer edge of the cone of diaphragm 813) of diaphragm 813 of speaker 810, four mounting sleeves 832 (832a, 832b) for screwing speaker 810 and rear cover 820 to front door 102, and a horizontally elongated elliptical sound hole plate 834 that is fitted inside diaphragm support part 831.

[0402] The height of the frame support part 831 (height from the rear surface of the front door 102) is designed to be higher than the maximum vibration amplitude of the diaphragm 813 so as not to impede the vibration of the diaphragm 813 of the speaker 810, and a sound hole plate 834 is fitted inside it, as shown in Figure 23(b).

[0403] As shown in FIG. 23(c), when speaker 810 is attached to speaker base 830, outer edge 813a of diaphragm 813 of speaker 810 abuts frame support 831, and an enclosed space is formed by speaker base 830 and diaphragm 813 of speaker 810.

[0404] According to this example, the periphery of the diaphragm 813 of the speaker 810 can be supported by the frame support portion 831, and an enclosed space can be formed by the speaker base portion 830 and the diaphragm 813 of the speaker 810, so that the sound output from the diaphragm 813 of the speaker 810 can be efficiently output toward the front surface of the front door 102 through the sound hole plate 834, thereby improving the acoustic effect.

[0405] Of the four mounting sleeves 832, the first mounting sleeves 832a, which are located at the upper left corner and lower right corner when viewed from above, are mounting sleeves to which dedicated screw holes 816a (first through holes) of the speaker 810 are fastened by screws 840, as shown in FIG. 23(c).

[0406] On the other hand, of the four mounting sleeves 832, the second mounting sleeves 832b located at the lower left corner and upper right corner when viewed from above are mounting sleeves in which the shared screw hole 816b (second through hole) of the speaker 810 and the screw hole 824 (third through hole) of the rear cover 820 are fastened by screws 840, as shown in FIG. 23(d).

[0407] In addition, two cylindrical ribs 838 are formed at a predetermined interval on the outer periphery of each of the four mounting sleeves 832 (832a, 832b) on which the four flange corner portions 814a (see FIG. 22) of the flange 814 of the speaker 810 can be placed.

[0408] According to this example, when attaching speaker 810 to speaker base 830, flange corner portion 814a of flange 814 of speaker 810 is placed on rib 838 of mounting sleeve 832, whereby positioning of speaker 810 can be easily and reliably performed and shifting or rattling of speaker 810 can be prevented when speaker 810 is attached.

[0409] <Speaker mounting structure (variation 2) / mounting method 1> Next, a first mounting method of the speaker unit 800 will be described with reference to FIG.

[0410] When attaching the speaker unit 800 to the speaker base 830, first, the speaker 810 is attached to the speaker base 830 as shown in Figures 23(b) and (c), and then the rear cover 820 is attached to the speaker base 830 as shown in the same figures (c) and (d).

[0411] More specifically, when attaching speaker 810 to speaker base 830, with lead terminal 816 of speaker 810 facing upward, flange corner 814a of flange 814 is placed on rib 838 of mounting sleeve 832, and dedicated screw hole 816a of speaker 810 is aligned with first mounting sleeve 832a while outer edge 813a of diaphragm 813 of speaker 810 is abutted against frame support portion 831, thereby positioning speaker 810 with respect to speaker base 830.

[0412] Next, as shown in FIG. 23(c), the dedicated screw hole 816a of the speaker 810 is aligned with the hole of the first mounting sleeve 832a of the speaker base portion 830 and fastened with a screw 840, thereby attaching only the speaker 810 to the speaker base portion 830.

[0413] Since lead terminal 816 and lead wire 817 of speaker 810 are configured to be detachable, even when the wiring of lead wire 817 to speaker base portion 830 is completed, it is possible to rotate speaker 810 by 90 degrees, 180 degrees, or 270 degrees and attach it to speaker base portion 830 and connect lead terminal 816 and lead wire 817 later, and even when speaker 810 is attached to speaker base portion 830, it is possible to change the wiring of lead wire 817 and connect lead terminal 816 and lead wire 817 later.

[0414] Next, when attaching rear cover 820 to speaker base portion 830, the position of box-shaped space 822S of rear cover 820 is aligned with the lead terminals 816 of speaker 810, and with the rear cover 820 facing upward, the screw holes 824 of rear cover 820 are aligned with the second mounting sleeve 832b, and rear cover 820 is positioned relative to speaker base portion 830 by covering speaker 810 with rear cover 820.

[0415] 23(d), the screw holes 824 of the rear cover 820 are aligned with the shared screw holes 816b of the speaker 810 and the holes of the second mounting sleeve 832b of the speaker base 830, and the rear cover 820 is attached to the speaker base 830 by fastening with screws 840. As a result, the speaker unit 800 is integrated and fixed to the back surface of the front door 102.

[0416] According to this example, when fixing speaker 810 and rear cover 820 to speaker base 830 with screw 840, it is possible to fix them at once with one screw 840 via shared screw hole 816b of speaker 810 and screw hole 824 of rear cover 820, so that the work of attaching the members can be simplified compared to the conventional method. Also, it is possible to fix rear cover 820 to speaker base 830 in a state where speaker 810 is fixed to the base and positioned using dedicated screw hole 816a, so that it is not necessary to position two members at the same time, and the work efficiency can be improved.

[0417] In addition, when the speaker unit 800 is correctly attached and the speaker 810 (first member) is covered with the rear cover 820 (second member), as shown in FIG. 23(d), the screw 840 attached to the dedicated screw hole 816a of the speaker 810 can be received in the through hole 825 (fourth through hole) without touching the inside of the through hole 825 (fourth through hole), and the screw 840 does not interfere with the rear cover 820. Therefore, depending on the positional relationship between the through hole 825 (fourth through hole) and the screw 840, the rear cover 820 can be fixed to the speaker 810. It is possible to easily visually check that rear cover 820 is attached in the correct position relative to speaker 810, and rear cover 820 can be accurately positioned relative to speaker 810. Furthermore, when rear cover 820 is accurately positioned relative to speaker 810, screws 840 are accommodated inside through holes 825 and the horizontal movement of rear cover 820 is regulated by screws 840, thereby preventing rear cover 820 from shifting or rattling when rear cover 820 is attached.

[0418] In particular, when screws are used as the fixing means, if the screws are not tightly fastened when fixing speaker 810 (first member) to speaker base 830 (base), there is a possibility that the screw head will protrude more than necessary from dedicated screw hole 816a (first through hole); however, by forming through hole 825 (fourth through hole) in rear cover 820, it is possible to avoid the risk of interference between rear cover 820 (second member) and the screw head.

[0419] In other words, when the speaker unit 800 is correctly attached and the speaker 810 (first member) is covered with the rear cover 820 (second member), the dedicated screw hole 816a (first through hole) of the speaker 810 (first member) is configured not to be covered by the rear cover 820 (second member) and the screw 840 is configured to contact only the speaker 810 (first member). Therefore, even when the rear cover 820 (second member) is positioned relative to the speaker base 830 (base), the dedicated screw hole 816a (first through hole) of the speaker 810 (first member) is not covered by the rear cover 820 (second member). a (first through hole) is not obscured by the rear cover 820 (second member), allowing the installation work to be performed efficiently. In addition, even if the speaker 810 (first member) and rear cover 820 (second member) are first fixed to the speaker base part 830 (base) using the shared screw hole 816b (second through hole) of the speaker 810 and the screw hole 824 (third through hole) of the rear cover 820, it is possible to thereafter fix the speaker 810 (first member) using the dedicated screw hole 816a (first through hole), thereby making the installation work more convenient.

[0420] Furthermore, when attaching speaker 810 and rear cover 820, common screws 840 (screws of the same length and thickness) can be used, eliminating the need to use multiple types of screws, improving convenience and eliminating screw installation errors, allowing the components to be attached reliably.

[0421] In addition, in order to use a common screw 840 when attaching the speaker 810 and the rear cover 820, the length of the screw 840 must be at least as long as the thickness of the screw hole 824 in the rear cover 820 plus the thickness of the shared screw hole 816b in the speaker 810.

[0422] For this reason, when a common screw 840 is used to fasten the dedicated screw hole 816a of the speaker 810, the length of the screw will be excessive by the thickness of the rear cover 820; however, in this example, the screw 840 attached to the dedicated screw hole 816a of the speaker 810 can be accommodated inside the through hole 825 (fourth through hole), and therefore the screw 840 does not interfere with the rear cover 820.

[0423] Furthermore, as shown in FIG. 23(d), when the speaker 810 and rear cover 820 are attached to the speaker base 830, the four attached screws 840 are visible. Therefore, even if a fraudulent person were to try to remove the speaker unit 800, this would make them think that it would take a long time to remove the speaker unit, thereby preventing fraudulent acts from occurring.

[0424] Furthermore, when the speaker 810 and rear cover 820 are attached to the speaker base 830, the speaker 810 and rear cover 820 are supported by the four mounting sleeves 832 of the speaker base 830, and therefore a predetermined space is formed between the speaker 810 and rear cover 820 and the speaker base 830.

[0425] As described with reference to FIG. 22, when the speaker 810 is covered with the rear cover 820, a space SP is also formed between the speaker 810 and the rear cover 820.

[0426] With this configuration, spaces are formed between the speaker base 830 (base) and the rear cover 820 (second member), and between the speaker 810 (first member) and the rear cover 820 (second member), and it is possible to pull out the lead wires 817 (wiring) of the speaker 810 to the outside of the speaker 810 (first member) and the rear cover 820 (second member) through these spaces.

[0427] <Speaker mounting structure (variation 2) / mounting method 2> Next, a second mounting method for the speaker unit 800 will be described.

[0428] In speaker unit 800, even if speaker 810 and rear cover 820 are first attached to speaker base 830 using shared screw hole 816b of speaker 810 and screw hole 824 of rear cover 820, dedicated screw hole 816a of speaker 810 can be fastened with screw 840 later.

[0429] More specifically, when first assembling the speaker 810 and rear cover 820 and attaching them to the speaker base 830, the position of the lead terminal 816 of the speaker 810 is aligned with the position of the box-shaped space 822S of the rear cover 820, and then the speaker 810 is covered and integrated with the rear cover 820, and the shared screw hole 816b of the speaker 810 and the screw hole 824 of the rear cover 820 are aligned with the second mounting sleeve 832b, thereby positioning the speaker 810 and rear cover 820 relative to the speaker base 830.

[0430] Next, the shared screw hole 816b of the speaker 810 and the screw hole 824 of the rear cover 820 are aligned with the holes of the second mounting sleeve 832b and fastened with a screw 840, thereby attaching the speaker 810 and the rear cover 820 together to the speaker base 830.

[0431] When the speaker 810 is completely attached to the speaker base 830, the speaker 810 is positioned relative to the speaker base 830 by aligning the dedicated screw hole 816a of the speaker 810 with the first mounting sleeve 832a.

[0432] Next, the dedicated screw hole 816a of the speaker 810 is aligned with the hole of the first mounting sleeve 832a of the speaker base part 830, and the speaker 810 is attached to the speaker base part 830 by fastening with the screw 840. As a result, the speaker unit 800 is integrated and fixed to the back surface of the front door 102.

[0433] According to this example, an appropriate mounting method can be selected from the multiple mounting methods (mounting methods 1 and 2) depending on the skill of the worker, thereby improving work efficiency.

[0434] <Speaker mounting structure (variation 2) / 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 including a first member (for example, the speaker 810 shown in FIG. 20 or FIG. 21(c) or (d)) that can be fixed to a base (for example, the speaker base part 830 shown in FIG. 20 or FIG. 23) and a second member (for example, the back cover 820 shown in FIG. 20 or FIG. 21(a) or (b)) that can cover at least a part of the first member, the first member including a plurality of first through holes (for example, the dedicated screw hole 816a shown in FIG. 21(d)) and a plurality of second through holes different from the first through holes (for example, the shared screw hole 816b shown in FIG. 21(d)), the second member including a plurality of third through holes (for example, the screw hole 824 shown in FIG. 21(b)), the first through holes being fixed to the first member and the second member, the first through hole is a through hole used when fixing the first member to the base, the second through hole and the third through hole are through holes used when fixing both the first member and the second member to the base, the plurality of first through holes are configured so that when the plurality of first through holes and the second through holes on both sides of the plurality of first through holes are connected with imaginary straight lines (e.g., straight line VL shown in FIG. 21(d)), an imaginary rectangle (e.g., rectangle VQ shown in FIG. 21(d)) is formed, the plurality of first through holes are configured to be positioned at the vertices of the ends of the imaginary rectangle, and the base has a frame portion (e.g., diaphragm support portion 831 shown in FIG. 20 or FIG. 23(a)) formed to match the shape of the first member (e.g., outer edge portion 813a of diaphragm 813 of speaker 810).

[0435] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the installation work of the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, the first through hole is arranged between the multiple second through holes, and is configured so that a virtual rectangle is formed when the multiple first through holes and the second through holes on both sides of the multiple first through holes are connected by virtual straight lines, and the multiple first through holes are configured to be arranged at the vertices of the ends of the virtual rectangle, so that the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, since the base has a frame portion formed to match the shape of the first member, the first member can be attached while being securely positioned relative to the base, allowing the attachment work to be performed efficiently and the frame portion to stably fix the first member to the base.

[0436] Further, a gaming machine according to this embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 810 shown in FIG. 20 or FIG. 21(c) or (d)) that can be fixed to a base (for example, the speaker base part 830 shown in FIG. 20 or FIG. 23) and a second member (for example, a back cover 820 shown in FIG. 20 or FIG. 21(a) or (b)) that can cover at least a part of the first member, the first member including a plurality of first through holes (for example, a dedicated screw hole 816a shown in FIG. 21(d)) and a plurality of second through holes different from the first through holes (for example, a shared screw hole 816b shown in FIG. 21(d)), the second member including a plurality of third through holes (for example, a screw hole 824 shown in FIG. 21(b)), the first through hole being a hole that is provided between the first member and the second member, and the second member including a plurality of third through holes. the second through hole and the third through hole are through holes used when fixing the first member and the second member to the base, the plurality of first through holes and the second through holes on both sides of the plurality of first through holes are connected with imaginary straight lines (e.g., straight line VL shown in FIG. 21(d)) to form an imaginary rectangle (e.g., rectangle VQ shown in FIG. 21(d)), the plurality of first through holes are configured to be positioned at vertices of diagonal ends of the imaginary rectangle, and when the first member and the second member are fixed to the base, a portion of the second member abuts against a support portion provided on the base, thereby forming a space between the second member and the base.

[0437] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, the first through hole is arranged between the multiple second through holes, and is configured so that a virtual rectangle is formed when the multiple first through holes and the second through holes on both sides of the multiple first through holes are connected by virtual straight lines, and the multiple first through holes are configured to be arranged at the vertices of the diagonal ends of the virtual rectangle, so that the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. Furthermore, when the first member and the second member are fixed to the base, a part of the second member abuts against a support portion provided on the base, thereby forming a space between the second member and the base. Therefore, even if the first member has wiring, etc., the wiring, etc. can be pulled out to the outside through the space, thereby increasing the freedom of design.

[0438] In addition, the gaming machine according to the present embodiment (for example, the slot machine 100 shown in FIG. 1) is a gaming machine including a first member (for example, the speaker 810 shown in FIG. 20 or FIG. 21(c) or (d)) that can be fixed to a base (for example, the speaker base part 830 shown in FIG. 20 or FIG. 23) and a second member (for example, the back cover 820 shown in FIG. 20 or FIG. 21(a) or (b)) that can cover at least a part of the first member, and the first member has a plurality of first through holes (for example, For example, the second member has a dedicated screw hole 816a shown in FIG. 21(d) and a plurality of second through holes different from the first through hole (for example, a shared screw hole 816b shown in FIG. 21(d)), the second member has a plurality of third through holes (for example, a screw hole 824 shown in FIG. 21(b)), the first through hole is a through hole used when fixing the first member of the first member and the second member to the base, and the second through hole and the third through hole are a through hole used when fixing both the first member and the second member to the base, the first through holes being configured to be connected to the second through holes on both sides of the first through holes by imaginary straight lines (e.g., straight line VL shown in FIG. 21(d)) to form an imaginary rectangle (e.g., rectangle VQ shown in FIG. 21(d)), the first through holes being configured to be arranged at vertices of ends of diagonal lines of the imaginary rectangle, the base being configured to have a frame portion (e.g., diaphragm support portion 831 shown in FIG. 20 or FIG. 23(a)) formed to match the shape of the first member (e.g., outer edge portion 813a of diaphragm 813 of speaker 810), and the first member and the second member being fixed to the base, a part of the second member abutting against a support portion provided on the base to form a space between the second member and the base.

[0439] According to the game machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at once through the second through hole of the first member and the third through hole of the second member, so that the work of attaching the members can be simplified compared to the conventional art, and the two first members and the second members can be stably fixed. In addition, since the second member can be fixed to the base in a state in which the first member is fixed to the base and positioned using the first through hole, it is not necessary to position the two members simultaneously, and the work efficiency can be improved. In addition, the first through hole is arranged between the multiple second through holes, and is configured so that a virtual rectangle is formed when the multiple first through holes and the second through holes on both sides of the multiple first through holes are connected by virtual straight lines, and the multiple first through holes are configured to be arranged at the vertices of the diagonal ends of the virtual rectangle, so that the two first members and the second members can be stably fixed by the second through holes arranged on both sides of the first through hole. In addition, since the base includes a frame portion formed to match the shape of the first member, the first member can be attached in a state where it is reliably positioned relative to the base, and the attachment work can be performed efficiently, and the frame portion allows the first member to be stably fixed to the base. In addition, since the first member and the second member are fixed to the base, and a part of the second member abuts against a support portion provided on the base, a space is formed between the second member and the base, so that even if the first member has wiring or the like, the wiring or the like can be drawn out to the outside through the space, and the degree of freedom in design can be increased.

[0440] Furthermore, the first member may be configured to be fixable to the base by a first fixing means (e.g., screw 840 shown in FIG. 20(a) or FIG. 23(d)) and a second fixing means (e.g., screw 840 shown in FIG. 20(a) or FIG. 23(d)), the second member may be configured to be fixable to the base by the second fixing means, and in a state in which the first member and the second member are fixed to the base (hereinafter referred to as the "first state"), the first through hole of the first member is configured not to be covered by the second member, and in the first state, the first fixing means may be configured to contact only the first member of the first member and the second member.

[0441] With this configuration, even when the second member is positioned relative to the base, the first through hole of the first member is not obscured by the second member, and the installation work can be performed efficiently. Furthermore, even if the first member and the second member are first fixed to the base using the second through hole and the third through hole, it is possible to thereafter fix the first member using the first through hole, thereby making the installation work more convenient.

[0442] Furthermore, the second member may have a plurality of fourth through holes (for example, through hole 825 shown in Figure 21 (b) or Figure 23 (d)), the third through hole being a through hole that is arranged at a position corresponding to the second through hole of the first member in the first state, the fourth through hole being a through hole that is arranged at a position corresponding to the first through hole of the first member in the first state, the size of the fourth through hole being larger than the size of the third through hole, and the second fixing means may be configured to be visible through the fourth through hole in the first state.

[0443] With this configuration, when the first member or the second member is correctly attached to the base and the first member is covered with the second member, the fixing means attached to the first through hole of the first member can be accommodated inside the fourth through hole, and the fixing means does not interfere with the second member, so that it is possible to easily visually confirm that the second member is attached to the first member in the correct position due to the positional relationship between the fourth through hole and the fixing means, and the second member can be accurately positioned relative to the first member, and when the second member is accurately positioned relative to the first member, the fixing means is accommodated inside the fourth through hole, and the movement of the second member is restricted by the fixing means, so that the second member can be prevented from shifting or rattling when the second member is attached. Also, since the fixing means can be seen through the third through hole and the fourth through hole, even if a fraudster tries to remove the first member or the second member, it can be made to think that it will take a long time to remove them, and fraud and the like can be prevented in advance.

[0444] Furthermore, the device may be configured so that, after the first through hole of the first member is fixed to the base by the first fixing means, the third through hole of the second member is positioned relative to the second through hole of the first member, and the second through hole of the first member and the third through hole of the second member are fixed to the base by the second fixing means; and, after the third through hole of the second member is positioned relative to the second through hole of the first member, the second through hole of the first member and the third through hole of the second member are fixed to the base by the second fixing means, the first through hole of the first member may be fixed to the base by the first fixing means.

[0445] With this configuration, an appropriate mounting method can be selected from a plurality of mounting methods depending on the skill of the worker, thereby improving work efficiency.

[0446] <Speaker mounting structure (variation 3) / speaker unit configuration> Next, the configuration of a speaker unit 850 according to Modification 3 will be described with reference to Fig. 24. Fig. 24(a) is an exploded perspective view of the speaker unit 850 according to Modification 3, and Fig. 24(b) is an external perspective view showing two speaker units 850 attached to the lower back surface of the front door 102.

[0447] As shown in FIG. 24(a), the speaker unit 850 of the third modified example is composed of a low-frequency output speaker 860 (first member) having a large diaphragm, and a rear cover 870 (second member) covering the rear side of the speaker 860, and is attached to speaker base portions 880 (left speaker base portion 880L, right speaker base portion 880R) arranged below the rear surface of the front door 102 (base) of the slot machine.

[0448] A left speaker base portion 880L and a right speaker base portion 880R are arranged horizontally at a predetermined distance from each other on the lower back surface of the front door 102, and a speaker unit 850 is configured to be attached to each of the left speaker base portion 880L and the right speaker base portion 880R.

[0449] Specifically, in the left speaker base portion 880L (first area) located on the left side of the front door 102 when viewed from behind, the speaker unit 850 is attached in a direction in which the box-shaped space 872S of the rear cover 870 and the lead terminal 866 of the speaker 860 face to the right when viewed from behind, and the lead wire 867 of the speaker 860 is pulled out from the right side (first orientation, hereinafter sometimes referred to as the "rightward direction").

[0450] On the other hand, in the right speaker base portion 880R (second area) located on the right side of the front door 102 when viewed from behind, the speaker unit 850 is attached in a direction in which the box-shaped space 872S of the rear cover 870 and the lead terminal 866 of the speaker 860 face left when viewed from behind, and the lead wire 867 of the speaker 860 is pulled out from the left side (second orientation, hereinafter sometimes referred to as the "leftward direction").

[0451] That is, in this example, the first member (speaker 860) and the second member (rear cover 870) can be attached to the base (front door 102) in either a first orientation (rightward) or a second orientation (leftward) in which the first member (speaker 860) and the second member (rear cover 870) are rotated 180 degrees circumferentially relative to the first orientation, and the first member (speaker 860) and the second member (rear cover 870) can be attached to the first area (left speaker base portion 880L) in the first orientation (rightward) and can be attached to the second area (right speaker base portion 880R) in the second orientation (leftward).

[0452] According to this example, the first member (speaker 860) and the second member (rear cover 870) can be attached to the base (front door 102) in at least two orientations, which increases the degree of freedom in attaching the first member (speaker 860) and the second member (rear cover 870), and allows them to be attached in accordance with the structure and specifications of the gaming machine.

[0453] Also, in this example, the first member (speaker 860) and the second member (rear cover 870) in the first orientation (right-facing) can be attached to the first area (left speaker base portion 880L) but cannot be attached to the second area (right speaker base portion 880R), and the first member (speaker 860) and the second member (rear cover 870) in the second orientation can be attached to the second area (right speaker base portion 880R) but cannot be attached to the first area (left speaker base portion 880L).

[0454] According to this example, the degree of freedom in attaching the first member (speaker 860) and the second member (rear cover 870) can be increased, and they can be attached according to the structure and specifications of the gaming machine, while also preventing installation errors.

[0455] As shown in Figure 24(b), the lead wires 867 of the two left and right speakers 860 pass through the inner space of the box-shaped space 872S of the rear cover 870, are pulled out to the outside through an opening formed on the front of the box-shaped space 872S, are wired along the rear surface of the front door 102, and are electrically connected to a sound output control means (for example, the sound source IC 418 of the first sub-control unit 400 described using Figure 3, or the second sub-control unit 500) arranged above the front door 102.

[0456] According to this example, the first member (speaker 860) and the second member (rear cover 870) attached to the first area (left speaker base portion 880L) are disposed opposite the first member (speaker 860) and the second member (rear cover 870) attached to the second area (right speaker base portion 880R) (one speaker unit 850 is attached facing right, while the other speaker unit 850 is attached facing left so as to face the one speaker unit 850), so that, as shown in FIG. 24(b), the lead wires 867 of each of the first members (speakers 860) can be drawn out toward the center of the rear surface of the base (front door 102), which not only makes it easy to route the wiring and improves the efficiency of the wiring work, but also allows the wiring to be organized and stored, improving maintainability.

[0457] The manner in which the lead wire 867 of the speaker 860 is pulled out is not limited to this example, and may, for example, be passed through the inner space of the box-shaped space 872S of the rear cover 870, pulled out from the space formed between the rear cover 870 and the front door 102 to the outside, wired along the rear surface of the front door 102, and electrically connected to a sound output control means arranged above the front door 102.

[0458] Furthermore, for example, when applied to a gaming machine in which it is difficult to secure space above the speaker unit 850 (for example, a slot machine in which a hopper, medal selector, etc. are arranged above the speaker unit 850, or a pachinko machine in which a lower tray, etc. are arranged above the speaker unit 850), the lead wire 867 of the speaker 860 can be routed to avoid other devices arranged above the speaker unit 850, which not only increases the efficiency of the wiring work but also enables the effective use of the limited space behind the front door 102.

[0459] In this example, two speaker units 850 are arranged horizontally on the back surface of the front door 102, but three or more speaker units 850 may be arranged, and the speaker units 850 may be arranged vertically or diagonally on the back surface of the front door 102.

[0460] In addition, the length of the lead wire 867 of the speaker 860 is not particularly limited as long as it has a length that allows electrical connection from the speaker 860 to a sound output control means (for example, the sound source IC 418 of the first sub-control unit 400 described using Figure 3, or the second sub-control unit 500); however, for example, if the length is set to the minimum required when the speaker unit 850 is installed in a left-facing or right-facing direction, and the lead wire 867 is configured so that it is not long enough to connect to the sound output control means when the speaker unit 850 is installed in a downward direction (in a direction in which the box-shaped space 872S of the rear cover 870 or the lead terminal 866 of the speaker 860 faces downward when viewed from behind), the installation direction of the speaker unit 850 can be intentionally restricted, and installation errors of the speaker unit 850 on the gaming machine can be prevented in advance.

[0461] Furthermore, the "first orientation" according to the present invention is not limited to the rightward direction, and may be, for example, a downward direction (a direction in which the box-shaped space 872S of the rear cover 870 and the lead terminal 866 of the speaker 860 face downward in rear view, and the lead wire 867 of the speaker 860 is drawn from the lower side), an upward direction (a direction in which the box-shaped space 872S of the rear cover 870 and the lead terminal 866 of the speaker 860 face upward in rear view, and the lead wire 867 of the speaker 860 is drawn from the upper side), or another direction. Furthermore, the "second orientation" according to the present invention is not limited to the leftward direction, and may be the above-mentioned downward direction, upward direction, or another direction.

[0462] The orientations (first orientation, second orientation) of speaker 860 and rear cover 870 may be changed according to the direction in which lead wire 867 of speaker 860 is pulled out. The positions of mounting sleeves 882 of left speaker base part 880L and right speaker base part 880R described below may be changed as appropriate according to the orientations (first orientation, second orientation) of speaker 860 and rear cover 870 and the positions of holes provided therein.

[0463] <Speaker mounting structure (variation 3) / speaker base> As shown in Figure 24(a), left speaker base portion 880L and right speaker base portion 880R are composed of a circular diaphragm support portion 881 that supports the outer edge (the portion that supports the outer edge of the cone of diaphragm 863) of diaphragm 863 of speaker 860 (see Figure 25(c) etc.), a cylindrical mounting sleeve 882 for screwing speaker 860 and rear cover 870 to front door 102, and a circular sound hole plate 884 that fits inside diaphragm support portion 881.

[0464] <Speaker mounting structure (variation 3) / metal plate> A rectangular parallelepiped metal plate 885 (third member) is erected between the left speaker base 880L and the right speaker base 880R on the rear surface of the front door 102. This metal plate 885 is a member that functions as a frame ground because it is disposed on the front door 102 (metallic frame). For convenience of explanation, part of the metal plate 885 is shown in a see-through manner in Fig. 24(a) and is omitted in Fig. 24(b).

[0465] As shown in FIG. 24(a), the metal plate 885 is formed with a circular eighth through-hole 885a8 (eighth hole) and a tenth through-hole 885a10 (tenth hole).

[0466] The eighth through hole 885a8 (eighth hole) is a through hole for fixing the first member (speaker 860) in the first orientation (rightward) to the metal plate 885, and the tenth through hole 885a10 (tenth hole) is a through hole for fixing the first member (speaker 860) in the second orientation (leftward) to the metal plate 885 (details will be described later using Figures 25 to 28).

[0467] <Speaker mounting structure (variation 3) / speaker, rear cover> Next, speaker 860 and rear cover 870 constituting speaker unit 850 according to Modification 3 will be described in detail with reference to FIGS.

[0468] 25(a) is a side view of rear cover 870, and (b) is a top view of rear cover 870. Also, (c) is a side view of speaker 860, and (d) is a top view of speaker 860.

[0469] Moreover, Figure 26 is a rear view seen from the rear of front door 102 showing the state after speaker 860 and rear cover 870 have been positioned relative to front door 102, and Figure 27 is a rear view seen from the rear of front door 102 showing the state after speaker 860 and rear cover 870 have been attached to front door 102 with screws.

[0470] Also, Figure 28(a) is a side view of the speaker unit 850 attached to the left speaker base portion 880L, seen from the left side when viewed from behind, and Figure 28(b) is a side view of the speaker unit 850 attached to the left speaker base portion 880L, seen from the right side when viewed from behind.

[0471] <Speaker mounting structure (variation 3) / Speaker> Next, the speaker 860 (first member) will be described.

[0472] Speaker 860 (first component) is a cone-type dynamic speaker, and as shown in Figure 25 (c), is roughly composed of an electromagnetic circuit 861 consisting of a voice coil and a magnet, and vibrating a diaphragm 863 described later in response to an electrical signal, a frame 862 supporting this electromagnetic circuit 861, diaphragm 863 that vibrates to generate sound, a flat flange 864 to which diaphragm 863 is fixed so that it can vibrate, a lead terminal 866 arranged on this flange 864, and a lead wire 867 detachably connected to this lead terminal 866.

[0473] Frame 862 is a cylindrical metal ring frame that widens slightly toward the front, and has a plurality of openings 865 (see FIG. 24) formed along the circumferential direction on the side surface for allowing air around diaphragm 863 to escape. That is, a plurality of openings 855 are formed along the circumferential direction on the side surface of frame 862, and supports 862a (see FIG. 24) are formed along the front-rear direction between openings 865. Diaphragm 863 is formed in a cone shape that opens toward the front, using a flexible material such as paper, for example.

[0474] A predetermined marking 876 (in this example, a part number and a material) is provided on the electromagnetic circuit 861. The display form of the predetermined marking 876 is not particularly limited, but in this example, a part number marking indicating the part number of the speaker 860 (in this example, a character string "SPxxxx") and a material marking indicating the material of the speaker 860 (in this example, a character string "AL") are engraved on the surface of the electromagnetic circuit 861.

[0475] According to this example, since the speaker 860 is provided with a predetermined marking 876, the orientation of the speaker 860 (the above-mentioned first orientation or second orientation) can be easily identified by the orientation of this predetermined marking 876, thereby improving convenience when installing the speaker 860, etc.

[0476] <Speaker mounting structure (variation 3) / Speaker / First and fourth through holes> As shown in FIG. 25(d), a flange 864 of the speaker 860 has an elliptical first through-hole 864a1 (first hole) formed in the lower left corner of the outer end portion thereof.

[0477] This first through hole 864a1 (first hole) is a hole used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in a first orientation (rightward), as shown in FIG. 27, and is a hole not used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in a second orientation (leftward).

[0478] In other words, the first through hole 864a1 (first hole) is a hole that may or may not be used when attaching the first component (speaker 860) and the second component (rear cover 870) to the base (front door 102).

[0479] According to this example, the first through hole 864a1 (first hole) may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102), and therefore the installation work of the first member (speaker 860) and the second member (rear cover 870) can be simplified, which may improve work efficiency.

[0480] An identifier may be provided (for example, by printing letters or symbols near the first hole, forming a protrusion or other portion near the first hole, or attaching a sticker near the first hole) that can identify whether the first through hole 864a1 (first hole) is a hole used when attaching the first member and / or the second member to the base, and the member on which the identifier is provided may be any of the first member, the second member, the third member, and the base, or may be another member. The same applies to the through holes described below.

[0481] According to this example, an identifier is provided that can determine whether a certain through hole is a hole to be used when attaching a first member and / or a second member to a base, thereby preventing installation errors when attaching the first member and / or the second member to a base and improving work efficiency.

[0482] The flange 864 of the speaker 860 has an oval-shaped fourth through-hole 864a4 (fourth hole) formed in the upper left corner of the outer end portion thereof.

[0483] This fourth through hole 864a4 (fourth hole) is a hole that is not used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in a first orientation (rightward), as shown in FIG. 27, and is a hole that is used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in a second orientation (leftward).

[0484] In other words, the fourth through hole 864a4 (fourth hole) is a hole that may or may not be used when attaching the first component (speaker 860) and the second component (rear cover 870) to the base (front door 102).

[0485] According to this example, the fourth through hole 864a4 (fourth hole) may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102), so that the installation work of the first member (speaker 860) and the second member (rear cover 870) can be simplified and work efficiency can be improved in some cases.

[0486] In this example, the first hole (first through hole 864a1) and the fourth hole (fourth through hole 864a4) of the first member (speaker 860) are arranged at positions that are approximately linearly symmetrical (positions that are approximately the same shortest distance from the imaginary line VL3) based on the imaginary line VL3 (see Figure 25 (d)) that passes through the center of the first member (speaker 860).

[0487] <Speaker mounting structure (variation 3) / Speaker / 7th and 9th through holes> The flange 864 of the speaker 860 has an oval-shaped seventh through-hole 864a7 (seventh hole) formed in the lower right corner of the outer end portion thereof.

[0488] This seventh through hole 864a7 (seventh hole) is a hole used when attaching the first member (speaker 860) to the third member (metal plate 885) in the first orientation (rightward) as shown in FIG. 27, and is a hole not used when attaching the first member (speaker 860) to the base (right speaker base portion 880R of front door 102) or the third member (metal plate 885) in the second orientation (leftward).

[0489] In other words, the seventh through hole 864a7 (seventh hole) is a hole that may or may not be used when attaching the first member (speaker 860) to the base (front door 102) or the third member (metal plate 885), and unlike the first through hole 864a1 and the fourth through hole 864a4, it is a hole that is not used when attaching the second member (rear cover 870).

[0490] The seventh through hole 864a7 (seventh hole) may be a hole used when attaching the first member (speaker 860) to the base (left speaker base portion 880L of the front door 102) in the first orientation (rightward).

[0491] In the upper right corner of the outer end portion of the flange 864 of the speaker 860, a ninth through hole 864a9 (ninth hole) having an elliptical shape is formed.

[0492] As shown in FIG. 27, this ninth through hole 864a9 (ninth hole) is a hole that is not used when attaching the first member (speaker 860) to the base (left speaker base portion 880L of front door 102) or the third member (metal plate 885) in the first orientation (rightward), and is a hole that is used when attaching the first member (speaker 860) to the third member (metal plate 885) in the second orientation (leftward).Unlike the first through hole 864a1 and the fourth through hole 864a4, this hole is not used when attaching the second member (rear cover 870).

[0493] In other words, the ninth through hole 864a9 (ninth hole) is a hole that may or may not be used when attaching the first member (speaker 860) to the base (front door 102) or the third member (metal plate 885).

[0494] The ninth through hole 864a9 (ninth hole) may be a hole used when attaching the first member (speaker 860) to the base (right speaker base portion 880R of front door 102) in the second orientation (leftward).

[0495] In this example, the seventh hole (seventh through hole 864a7) and the ninth hole (ninth through hole 864a9) of the first member (speaker 860) are arranged at positions that are approximately linearly symmetrical (positions that are approximately the same shortest distance from the imaginary line VL3) based on the imaginary line VL3 (see Figure 25 (d)) that passes through the center of the first member (speaker 860).

[0496] <Speaker mounting structure (variation 3) / Speaker / 1st, 4th, 7th, 9th through holes> As shown in FIG. 25(d), when the four through holes, the first through hole 864a1, the fourth through hole 864a4, the seventh through hole 864a7, and the ninth through hole 864a9, are connected by a virtual straight line VL4, a virtual rectangle VQ4 is formed, and the first through hole 864a1 and the ninth through hole 864a9 are arranged on the (first) diagonal (the vertices at the ends of the diagonal) of the virtual rectangle VQ, and the fourth through hole 864a4 and the seventh through hole 864a7 are arranged on the second diagonal (different from the first diagonal) of the virtual rectangle VQ4 (the vertices at the ends of the diagonal).

[0497] The sizes and shapes of the four through holes, the first through hole 864a1, the fourth through hole 864a4, the seventh through hole 864a7, and the ninth through hole 864a9, are not particularly limited, but in this example, as shown in FIG. 26, the four through holes, the first through hole 864a1, the fourth through hole 864a4, the seventh through hole 864a7, and the ninth through hole 864a9, are configured as elliptical holes having larger outer diameters than the circular second through hole 872a2 and the fifth through hole 872a5 of the rear cover 870.

[0498] According to this example, the four through holes, the first through hole 864a1, the fourth through hole 864a4, the seventh through hole 864a7, and the ninth through hole 864a9, are configured as elliptical holes having a larger outer diameter than the circular second through hole 872a2 and the fifth through hole 872a5 of the rear cover 870. This makes it possible to absorb an assembly error (misalignment of the rear cover 870) of the rear cover 870 relative to the speaker 860, and simplifies the installation work.

[0499] <Speaker mounting structure (variation 3) / rear cover> Next, the rear cover 870 (second member) will be described.

[0500] Rear cover 870 (second member) is a colored transparent resin member capable of housing speaker 860 therein, and is made of a material that allows speaker 860 to be seen from the outside when speaker 860 is housed inside.

[0501] According to this example, at least a portion of speaker 860 can be seen through rear cover 870, and therefore, when installing speaker unit 850, the installation work can be performed while checking the positional relationship between speaker 860 and rear cover 870, etc., thereby making the installation work more convenient.

[0502] In addition, rear cover 870 may be any transparent material, and its material is not limited to colored transparent resin, but may be, for example, colorless transparent (or translucent) plastic, acrylic, polycarbonate, polyvinyl chloride, glass, metal, etc.

[0503] Furthermore, the shape of rear cover 870 is not particularly limited, but at least a portion may be formed with a shape (for example, a lattice shape or a maze shape) that can prevent foreign matter such as dirt and dust from entering and adhering to speaker 860. Furthermore, rear cover 870 may be formed with a guide portion (hook or the like) for guiding lead wire 867 (wiring) of speaker 860, a ground wire connecting speaker 860 and metal plate 885 (frame ground) to a predetermined position, or the guide portion may be configured to be attachable to rear cover 870 later.

[0504] As shown in Figures 25(a) and (b), rear cover 870 has a circular ring-shaped cover portion 871 formed on the rear side that covers part of the rear end of speaker 860, and has a cylindrical side wall portion 872 that widens slightly toward the rear, with this cover portion 871 as its base end.

[0505] <Speaker mounting structure (variation 3) / rear cover / second and fifth through holes> A circular second through-hole 872a2 (second hole) is formed in the lower left corner of the outer edge of the side wall portion 872 of the rear cover 870.

[0506] This second through hole 872a2 (second hole) is a hole used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in a first orientation (rightward), as shown in FIG. 27, and is a hole not used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in a second orientation (leftward).

[0507] In other words, the second through hole 872a2 (second hole) is a hole that may or may not be used when attaching the first component (speaker 860) and the second component (rear cover 870) to the base (front door 102).

[0508] According to this example, the second through hole 872a2 (second hole) may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102), and therefore the installation work of the first member (speaker 860) and the second member (rear cover 870) can be simplified, which may improve work efficiency.

[0509] A fifth through-hole 872a5 (fifth hole) having a circular shape is formed in the upper left corner of the outer edge of the side wall portion 872 of the rear cover 870.

[0510] This fifth through hole 872a5 (fifth hole) is a hole that is not used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in the first orientation (rightward), as shown in FIG. 27, and is a hole that is used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in the second orientation (leftward).

[0511] In other words, the fifth through hole 872a5 (fifth hole) is a hole that may or may not be used when attaching the first component (speaker 860) and the second component (rear cover 870) to the base (front door 102).

[0512] According to this example, the fifth through hole 872a5 (fifth hole) may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102), and therefore the installation work of the first member (speaker 860) and the second member (rear cover 870) can be simplified, which may improve work efficiency.

[0513] In this example, the second hole (second through hole 872a2) and the fifth hole (fifth through hole 872a5) of the second member (rear cover 870) are arranged at positions that are approximately linearly symmetrical (positions that are approximately the same shortest distance from the imaginary line VL5) based on the imaginary line VL5 (see Figure 25 (b)) that passes through the center of the second member (rear cover 870).

[0514] <Speaker mounting structure (variation 3) / rear cover / third and sixth through holes> As shown in Figure 25 (b), the rear cover 870 has a left protruding piece 873 that protrudes outward to the left from the outer edge of the side wall portion 872, and a right protruding piece 874 that protrudes outward to the right from the outer edge of the side wall portion 872.

[0515] Above the left protruding piece 873 and the right protruding piece 874 of the rear cover 870, a third circular through-hole 873a3 (third hole) is formed.

[0516] This third through hole 873a3 (third hole) is a hole used when attaching the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in the first orientation (rightward), as shown in FIG. 27, and is a hole not used when attaching the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in the second orientation (leftward).

[0517] In other words, the third through hole 873a3 (third hole) is a hole that may or may not be used when attaching the second member (rear cover 870) to the base (front door 102).

[0518] According to this example, the third through hole 873a3 (third hole) may not be used when attaching the second member (rear cover 870) to the base (right speaker base portion 880R of the front door 102), so that the attachment work of the second member (rear cover 870) can be simplified and work efficiency can be improved in some cases.

[0519] Either one of the two third through holes 873a3 (third holes) may be used for attachment to the third member (metal plate 885).

[0520] Below the left protruding piece 873 and the right protruding piece 874 of the rear cover 870, a sixth circular through-hole 873a6 (sixth hole) is formed.

[0521] This sixth through hole 873a6 (sixth hole) is a hole that is not used when attaching the second member (rear cover 870) to the base (left speaker base portion 880L of front door 102) in the first orientation (rightward), as shown in FIG. 27, and is a hole that is used when attaching the second member (rear cover 870) to the base (right speaker base portion 880R of front door 102) in the second orientation (leftward).

[0522] In other words, the sixth through hole 873a6 (sixth hole) is a hole that may or may not be used when attaching the second member (rear cover 870) to the base (front door 102).

[0523] According to this example, the sixth through hole 873a6 (sixth hole) may not be used when attaching the second member (rear cover 870) to the base (right speaker base portion 880R of the front door 102), so that the attachment work of the second member (rear cover 870) can be simplified and work efficiency can be improved in some cases.

[0524] Either one of the two sixth through holes 873a6 (sixth holes) may be used for attachment to the third member (metal plate 885).

[0525] In this example, the third hole (third through hole 873a3) and the sixth hole (sixth through hole 873a6) of the second member (rear cover 870) are arranged at positions that are approximately linearly symmetrical (positions that are approximately the same shortest distance from the imaginary line VL5) based on the imaginary line VL5 (see Figure 25 (b)) that passes through the center of the second member (rear cover 870).

[0526] It should be noted that predetermined markings 877 (in this example, a part number and a material) are provided on cover portion 871 of rear cover 870. The display form of predetermined markings 877 is not particularly limited, but in this example, a part number marking indicating the part number of rear cover 870 (in this example, a character string "CVxxxx") and a material marking indicating the material of rear cover 870 (in this example, a character string "PC") are engraved on the surface of cover portion 871.

[0527] According to this example, a predetermined marking 877 is provided on the rear cover 870, and therefore the orientation of the rear cover 870 (the above-mentioned first orientation or second orientation) can be easily identified by the orientation of this predetermined marking 877, thereby improving convenience when attaching the rear cover 870, etc.

[0528] In particular, since the specified markings 877 are provided in an area of ​​the cover portion 871 that is closer to the third through hole 873a3 (third hole) than the sixth through hole 873a6 (sixth hole) (an area above the imaginary line VL5 passing through the center of the rear cover 870), it is possible to recognize, using the specified markings 877 as a clue, that the third through hole 873a3 (third hole) is a hole used when attaching the second member (rear cover 870) to the base (left speaker base portion 880L of the front door 102) or the third member (metal plate 885) in the first orientation (rightward), thereby further increasing convenience when attaching the rear cover 870, etc.

[0529] <Speaker mounting structure (variation 3) / rear cover / box-shaped space> As shown in Figure 25 (b), a box-shaped space 872S (space portion) is protrudingly formed on the outer edge of the right side of the rear cover 870 when viewed from above, for storing the lead terminal 866 of the speaker 860 and leading the lead wire 867 to the outside of the speaker unit 850.

[0530] With this configuration, when speaker 860 is housed inside rear cover 870, a space is formed between speaker 860 and rear cover 870, and as shown in Figures 26 and 27, lead wire 867 (wiring) of speaker 860 can be pulled out to the outside of speaker 860 and rear cover 870 through this space.

[0531] According to this example, even if a part of the speaker 860 is covered by the rear cover 870, the lead wire 867 (wiring) of the speaker 860 can be drawn out to the outside, thereby increasing the degree of freedom in design.

[0532] In this example, the lead wire 867 is passed through the inner space of the box-shaped space 872S of the rear cover 870 and pulled out from an opening formed on the front side of the box-shaped space 872S to the outside; however, for example, a space may be formed between the speaker 860 and the front door 102, and the lead wire 867 may be pulled out from the front side of the speaker 860 to the front door 102 side through the space, in which case it is not necessary to form the box-shaped space 872S in the rear cover 870.

[0533] <Speaker mounting structure (variation 3) / mounting method> Next, a method for mounting the speaker unit 850 will be described.

[0534] As shown in Figures 27 and 28(a), the first member (speaker 860) and the second member (rear cover 870) in a first orientation (facing right) are attached to a base (mounting sleeve 882 of the left speaker base portion 880L of the front door 102) by a fixing means (screw 890) that penetrates the first hole (first through hole 864a1) of the first member (speaker 860) and the second hole (second through hole 872a2) of the second member (rear cover 870).

[0535] According to this example, it is possible to fix the first hole (first through hole 864a1) of the first member (speaker 860) and the second hole (second through hole 872a2) of the second member (rear cover 870) at once, which not only simplifies the work of attaching the members compared to conventional methods, but also enables the two first members (speaker 860) and the second member (rear cover 870) to be stably fixed.

[0536] In addition, the second member (rear cover 870) in the first orientation (rightward) is attached to the base (mounting sleeve 882 of the left speaker base portion 880L of the front door 102) by a fixing means (screw 890) that penetrates a third hole (third through hole 873a3) of the second member (rear cover 870).

[0537] The first member (speaker 860) and the second member (rear cover 870) in a first orientation (rightward) are attached vertically along the base (front door 102), and the first hole (first through hole 864a1) of the first member (speaker 860) and the second hole (second through hole 872a2) of the second member (rear cover 870) are positioned below a virtual line VL6 (see FIG. 27) passing through the center of the first member (speaker 860) or the second member (rear cover 870) in the vertical direction of the base (front door 102).

[0538] According to this example, the first member (speaker 860) and the second member (rear cover 870) can be fixed vertically downward to the base (left speaker base portion 880L of front door 102), so that the two first members (speaker 860) and the second member (rear cover 870) can be stably fixed.

[0539] 27 and 28(b), the second member (rear cover 870) in the first direction (rightward) is attached to the base (the mounting sleeve 882 of the left speaker base 880L of the front door 102) by a fixing means (screw 890) that penetrates the third hole (third through hole 873a3) of the second member (rear cover 870), and the first member (speaker 860) in the first direction (rightward) is attached to the eighth through hole 885a8 (eighth hole) of the third member (metal plate 885) by a fixing means (screw 890) that penetrates the seventh hole (seventh through hole 864a7) of the first member (speaker 860). As a result, the first member (speaker 860) in the first direction (rightward) is grounded (earthed).

[0540] When the right-facing speaker 860 and rear cover 870 are attached to the left speaker base portion 880L of the front door 102, most of the speaker 860 is contained within the inner space of the rear cover 870, and the flange 864 of the speaker 860 and the inner wall of the side wall portion 872 of the rear cover 872 (at least parts of the speaker 860 and rear cover 870) are configured to abut (or be in close proximity to) each other.

[0541] According to this example, when the second member (rear cover 870) is attached to the base (left speaker base portion 880L of front door 102), at least a portion of the second member (rear cover 870) abuts (or is close to) the first member (speaker 860) and is fixed so as to cover at least a portion of the first member (speaker 860), thereby enabling the two first members (speaker 860) and the second member (rear cover 870) to be stably fixed.

[0542] On the other hand, as shown in FIG. 27, the first member (speaker 860) and the second member (rear cover 870) in the second orientation (left) are attached to the base (mounting sleeve 882 of the right speaker base portion 880R of the front door 102) by a fixing means (screw 890) that penetrates the fourth hole (fourth through hole 864a4) of the first member (speaker 860) and the fifth hole (fifth through hole 872a5) of the second member (rear cover 870).

[0543] In addition, the second member (rear cover 870) facing the second direction (leftward) is attached to the base (mounting sleeve 882 of the right speaker base portion 880R of the front door 102) by a fixing means (screw 890) that penetrates through a sixth hole (sixth through hole 873a6) of the second member (rear cover 870).

[0544] The first member (speaker 860) and the second member (rear cover 870) in the second orientation (facing left) are attached vertically along the base (front door 102), and the fourth hole (fourth through hole 864a4) of the first member (speaker 860) and the fifth hole (fifth through hole 872a5) of the second member (rear cover 870) are positioned below a virtual line VL6 (see FIG. 27) passing through the center of the first member (speaker 860) or the second member (rear cover 870) in the vertical direction of the base (front door 102).

[0545] According to this example, the first member (speaker 860) and the second member (rear cover 870) can be fixed vertically downward to the base (right speaker base portion 880R of front door 102), so that the two first members (speaker 860) and the second member (rear cover 870) can be stably fixed.

[0546] 27, the second member (rear cover 870) in the second orientation (leftward) is attached to the base (the mounting sleeve 882 of the right speaker base 880R of the front door 102) by a fixing means (screw 890) that penetrates the sixth hole (sixth through hole 873a6) of the second member (rear cover 870), and the first member (speaker 860) in the second orientation (leftward) is attached to the tenth through hole 885a10 (tenth hole) of the third member (metal plate 885) by a fixing means (screw 890) that penetrates the ninth hole (ninth through hole 864a9) of the first member (speaker 860). As a result, the first member (speaker 860) in the second orientation (leftward) is grounded (earthed).

[0547] When the left-facing speaker 860 and rear cover 870 are attached to the right speaker base portion 880R of the front door 102, most of the speaker 860 is contained within the inner space of the rear cover 870, and the flange 864 of the speaker 860 and the inner wall of the side wall portion 872 of the rear cover 872 (at least parts of the speaker 860 and the rear cover 870) are configured to abut (or be in close proximity to) each other.

[0548] According to this example, when the second member (rear cover 870) is attached to the base (right speaker base portion 880R of front door 102), at least a portion of the second member (rear cover 870) abuts (or is close to) the first member (speaker 860) and is fixed so as to cover at least a portion of the first member (speaker 860), thereby enabling the two first members (speaker 860) and the second member (rear cover 870) to be stably fixed.

[0549] In this example, both the speaker 860 and the rear cover 870 are fixed to the front door 102 with screws, but the speaker 860 and the rear cover 870 may be attached to the front door 102 using all of the through holes (or some of the through holes) of the rear cover 870 with the speaker 860 housed in the inner space of the rear cover 870 without fixing the speaker 860 to the front door 102 (without using the through holes of the speaker 860).

[0550] According to this example, since there is no need to fix the speaker 860 to the front door 102, the installation work of the speaker unit 850 can be simplified, and by using all of the through holes in the rear cover 870, the speaker unit 850 can be more firmly attached to the front door 102.

[0551] <Speaker mounting structure (variation 3) / variation of metal plate> Next, a metal plate 915 according to a modified example will be described with reference to Fig. 29. Fig. 29 is a rear view of the state after the speaker 860 and the rear cover 870 are attached to the front door 102 with screws, as viewed from the rear of the front door 102.

[0552] In this example, a metal plate 915 (third member) smaller than the metal plate 885 described using FIGS. 25 to 28 is provided upright on the rear surface of the front door 102 between the left speaker base portion 880L and the right speaker base portion 880R.

[0553] Therefore, in this example, the rear cover 870 (second member) in the first orientation (rightward) is attached to the base (left speaker base portion 880L of the front door 102) by a fixing means (screw 890) that penetrates through the third hole (third through hole 873a3) of the second member (rear cover 870), and is attached to the third member (metal plate 915) by a fixing means (screw 890) that penetrates through the sixth hole (sixth through hole 873a6) of the second member (rear cover 870).

[0554] In addition, the rear cover 870 (second member) in the second orientation (facing left) is attached to the base (right speaker base portion 880R of the front door 102) by fixing means (screws 890) that penetrate through the sixth hole (sixth through hole 873a6) of the second member (rear cover 870), and is also attached to the third member (metal plate 915) by fixing means (screws 890) that penetrate through the third hole (third through hole 873a3) of the second member (rear cover 870).

[0555] That is, the third through hole 873a3 (third hole) is a hole used when attaching the second member (rear cover 870) to the base (left speaker base portion 880L of the front door 102) in the first orientation (rightward), as shown in FIG. 29, or when attachin...
