DETAILED DESCRIPTION OF THE INVENTION

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

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

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

[0012] In this embodiment, an appropriate number of each symbol is printed at equal intervals on a strip-shaped member, and this strip-shaped member is attached to a predetermined circular cylindrical frame to form each of the reels 110-112 (see FIG. 4). When viewed from the player, the symbols on the reels 110-112 are displayed in approximately three rows vertically through symbol display windows 113 provided in front of each of the reels 110-112, so that a total of nine symbols can be seen.

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

[0014] A backlight 264 (see FIG. 18) is disposed on the back of each of the reels 110 to 112 to illuminate the individual symbols displayed in the symbol display window 113 (details will be described later). Furthermore, an optical sensor (also called an index sensor, not shown) consisting of a light-emitting section and a light-receiving section is provided near each of the reels 110 to 112 inside the slot machine 100, and a light-shielding piece of a certain length provided on the reel passes between the light-emitting section and the light-receiving section of this optical sensor. The rotational position of the symbols on the reel is determined based on the detection results of this sensor, and the reels 110 to 112 are stopped so that the desired symbol is displayed on the pay line.

[0015] 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 below, or that a bonus game is in progress (special combination 1-2 game state). The 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 replayed (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.

[0016] 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, 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 lamps corresponding to the number of inserted medals, and when the specified number of medals have been inserted, the game start lamp 121 lights up to indicate that the game can be started.

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

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

[0019] The 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 effects. In this example, the stored number display 125, the game information display 126, and the payout number display 127 are 7-segment (SEG) displays.

[0020] 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 are inserted into the medal insertion slot 141 or the bet buttons 130 to 132 are operated and the start lever 135 is operated, the reels 110 to 112 start to rotate. The operation of the start lever 135 is called the game start operation.

[0021] The stop button unit 136 is provided with stop buttons (stop buttons) 137 to 139. The stop buttons 137 to 139 are button-type switches for individually stopping the reels 110 to 112 that have started to rotate by operating the start lever 135, and are associated with each of the reels 110 to 112. Note that a light emitting element may be provided inside each of the stop buttons 137 to 139, and when the stop buttons 137 to 139 can be operated, the light emitting element can be lit to notify the player.

[0022] Hereinafter, operations on stop buttons 137 to 139 will be referred to as stop operations, with the first stop operation being referred to as the first stop operation (hereinafter also referred to as "first stop" or "first stop"), the next stop operation being referred to as the second stop operation (hereinafter also referred to as "second stop" or "second stop"), and the final stop operation being referred to as the third stop operation (hereinafter also referred to as "third stop" or "third stop").

[0023] The reels that are stopped in response to these stop operations are referred to as the first stop reel, the second stop reel, and the third stop reel, respectively. Furthermore, the order in which the stop buttons 137 to 139 are operated to stop all of the reels 110 to 112 that are spinning is referred to as the operation order (or push order).

[0024] The operation sequence (pressing order) of the stop buttons 137 to 139, when the left stop button 137 is represented as "left or R", the middle stop button 138 as "middle or C", and the right stop button 139 as "right or R", are six types: (1) left-to-middle-to-right operation sequence (left-right-right or LCR), (2) left-to-right-to-middle operation sequence (left-right-center or LRC), (3) middle-to-left-to-right operation sequence (center-left-right or CLR), (4) middle-to-right-to-left operation sequence (center-right-left or CRL), (5) right-to-left-to-middle operation sequence (right-left-center or RLC), and (6) right-to-middle-to-left operation sequence (right-center-left or RCL).

[0025] The medal return button 133 is a button that can be pressed to remove medals that have been inserted and become stuck. The settlement button 134 is a button that can be used to settle medals electronically stored in the slot machine 100 and medals that have been bet, and to dispense them from the medal payout outlet 155. The door key hole 140 is a hole into which a key can be inserted to unlock the front door 102 of the slot machine 100.

[0026] Below the stop button unit 136, there is provided a title panel 162 on which the model name is displayed and various certificate stamps are attached. Below the title panel 162, there are provided a medal payout outlet 155 and a medal tray 161. The sound hole 181 is a hole for outputting sound from a speaker provided inside the slot machine 100 to the outside. The side lamps 144 provided on the left and right sides of the front door 102 are decorative lamps for livening up the game. A performance device 160 is provided above the front door 102, and a sound hole 143 is provided above the performance device 160.

[0027] This presentation device 160 is equipped with a shutter (shielding device) 163 consisting of two shutters, a right shutter 163a and a left shutter 163b, which can be opened and closed horizontally, and a liquid crystal display device 157 (presentation image display device) arranged at the back of this shutter 163, and is configured so that when the right shutter 163a and the left shutter 163b are opened horizontally outward in front of the liquid crystal display device 157, the display screen of the liquid crystal display device 157 appears in front of the slot machine 100 (on the player's side).

[0028] Note that any display device capable of displaying various effect images and various game information may be used, not limited to a liquid crystal display device. For example, a multi-segment display (7-segment display), a dot matrix display, an organic EL display, a plasma display, a reel (drum), or a display device consisting of a projector and a screen may be used. The display screen is rectangular and configured so that the entire screen is visible to the player. In this embodiment, the display screen is rectangular, but it may also be square. Furthermore, decorations (not shown) may be provided around the periphery of the display screen, so that a portion of the periphery of the display screen is hidden by the decoration, making the display screen appear irregularly shaped. In this embodiment, the display screen is flat, but it may also be curved.

[0029] Also provided inside the main body 101 are a setting key that can be turned on and off by a rotation operation, and a setting switch that can be pressed down to change settings (change setting values) or check settings. The setting key is an operating means for starting to change or check setting values ​​(settings 1 to 6 in this example), and the setting switch is one of the setting means that can set one setting value out of multiple setting values.

[0030] <Winning line> Next, the pay lines will be described with reference to Figure 2. Figure 2 is a diagram showing an example of the pay lines of the slot machine 100.

[0031] As explained using Figure 1, when viewed from the player, the symbols on the reels 110 to 112 are displayed in approximately three rows vertically through the symbol display windows 113 provided in front of each reel 110 to 112, so that a total of nine symbols can be seen.

[0032] Specifically, the symbol displayed on the top row of the left reel 110 (position 1 shown in the figure; also called symbol position 1) is called the left reel top row symbol, the symbol displayed on the middle row of the left reel 110 (position 2 shown in the figure; also called symbol position 2) is called the left reel middle row symbol, and the symbol displayed on the bottom row of the left reel 110 (position 3 shown in the figure; also called symbol position 3) is called the left reel bottom row symbol.

[0033] In addition, the pattern displayed on the top row of the middle reel 111 (position 4 shown in the figure; also called pattern position 4) is called the top row of the middle reel pattern, the pattern displayed on the middle row of the middle reel 111 (position 5 shown in the figure; also called pattern position 5) is called the middle row of the middle reel pattern, and the pattern displayed on the bottom row of the middle reel 111 (position 6 shown in the figure; also called pattern position 6) is called the bottom row of the middle reel pattern.

[0034] In addition, the symbol displayed on the top row of the right reel 112 (position 7 shown in the figure; also called symbol position 7) is called the right reel top row symbol, the symbol displayed on the middle row of the right reel 112 (position 8 shown in the figure; also called symbol position 8) is called the right reel middle row symbol, and the symbol displayed on the bottom row of the right reel 112 (position 9 shown in the figure; also called symbol position 9) is called the right reel bottom row symbol.

[0035] In this embodiment, the only winning line provided is the middle winning line L1 (hereinafter sometimes simply referred to as the "winning line L1"), which is composed of the middle pattern of the left reel (pattern position 2), the middle pattern of the middle reel (pattern position 5), and the middle pattern of the right reel (pattern position 8).

[0036] Here, the winning line is a line set at the stop position of the symbols visible through the symbol display window 113, and is a line that determines whether or not a symbol combination corresponding to a winning role, which will be explained using Fig. 5, is displayed (whether or not it is aligned). The winning line that is valid (hereinafter, may be simply referred to as "valid line") is predetermined based on the number of medals bet as gaming media.

[0037] The slot machine 100 of this embodiment is a three-coin bet-only machine, and when the number of inserted medals is less than three, no winning line is active, and when three medals are bet, the winning line L1 is active. When the winning line is active, the start lever 135 can be operated to start the game.

[0038] Hereinafter, in the symbol display window 113, symbol positions 2, 5, and 8 on the winning line L1 may be referred to as "winning positions," and other symbol positions, i.e., symbol positions 1, 3, 4, 6, 7, and 9, may be referred to as "non-winning positions." In other words, a winning position is a position on the winning line where a symbol that constitutes a symbol combination corresponding to a winning combination stops.

[0039] The number of winning lines is not limited to one. For example, in addition to the winning line L1, three lines in total may be set as valid winning lines: an upper winning line consisting of the upper symbols on the left reel, the upper symbols on the middle reel, and the upper symbols on the right reel, and a lower winning line consisting of the lower symbols on the left reel, the lower symbols on the middle reel, and the lower symbols on the right reel. Alternatively, a number of winning lines corresponding to the number of medals bet may be set as valid winning lines.

[0040] <Control unit> Next, the circuit configuration of the control unit of the slot machine 100 will be described in detail with reference to Figure 3. Note that Figure 3 shows a circuit block diagram of the control unit.

[0041] 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.

[0042] <Main control unit> First, we will explain the main control unit 300 of the slot machine 100. The main control unit 300 is equipped with a basic circuit 302 that controls the entire main control unit 300, and this basic circuit 302 is equipped with a CPU 304, a ROM 306 for storing control program data, lottery data used in the internal lottery for winning combinations, reel stop positions, etc., a RAM 308 for temporarily storing data, an I / O 310 for controlling the input and output of various devices, a counter timer 312 for measuring time, number of times, etc., and a WDT (watchdog timer) 314. Note that other storage devices may be used for the ROM 306 and RAM 308, and this also applies to the first sub-control unit 400 and second sub-control unit 500 described below.

[0043] The CPU 304 of this basic circuit 302 operates by receiving a clock signal with a predetermined cycle output by the crystal oscillator 315b as a system clock. Furthermore, when the power is turned on, the CPU 304 transmits frequency division data stored in a predetermined area of ​​the ROM 306 to the counter timer 312. The counter timer 312 determines an interrupt time based on the received frequency division data and transmits an interrupt request to the CPU 304 at each interrupt time. The CPU 304 monitors the sensors and transmits drive pulses in response to this interrupt request. For example, if the clock signal output by the crystal oscillator 315b is set to 8 MHz, the frequency division value of the counter timer 312 is set to 1 / 256, and the frequency division data in the ROM 306 is set to 47, the reference time for the interrupt is 256 × 47 ÷ 8 MHz = 1.504 ms.

[0044] The main control unit 300 is equipped with a random number generation circuit 316 (which is assumed to have two random number generation circuits built in) that derives a number in the range of 0 to 65535 each time it receives a clock signal output by the crystal oscillator 315a, and a start-up signal output circuit 338 that outputs a start-up signal (reset signal) when power is turned on.When a start-up signal is input from this start-up signal output circuit 338, the CPU 304 starts game control (starts the main processing of the main control unit, which will be described later).

[0045] The random number generation circuit 316 generates random numbers to be used in the basic circuit 302. The random number generation circuit 316 generates random numbers in two ways: counter mode and random number mode. In counter mode, a value that counts up (down) at a predetermined time interval is acquired and the acquired value is used as a random number. The random number mode has two further methods. In the first method, a seed value of the random number is used to perform a calculation using a predetermined function (e.g., a modulus function) and derive the result of this calculation as a random number. In the second method, a value is read from a random number table in which values ​​ranging from 0 to 65535 are randomly arranged, and the read value is used as a random number. The random number generation circuit 316 acquires irregular values ​​by utilizing white noise superimposed on signals input from various sensors 318 to the sensor circuit 320. The random number generation circuit 316 uses the value thus obtained as the initial value for a counter that counts up (down) in counter mode, as a seed for a random number, or when determining the start position for reading from the random number table.

[0046] 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.

[0047] When the sensor circuit 320 detects the H level of the start lever sensor, it outputs a signal indicating this detection to the random number generation circuit 316. Upon receiving this signal, the random number generation circuit 316 latches the value at that timing and stores it in a register that stores random numbers to be used in the lottery.

[0048] Two medal acceptance sensors are installed in the internal passage of the medal insertion slot 141 and detect whether a medal has passed through. Two start lever 135 sensors are installed inside the start lever 135 and detect the start operation by the player. Stop button 137 sensors, stop button 138 sensors, and stop button 139 sensors are installed on each of the stop buttons 137 to 139 and detect the operation of the stop button by the player.

[0049] The bet button 130 sensor, bet button 131 sensor, and bet button 132 sensor are provided on each of the medal insertion buttons 130 to 132, and detect the insertion operation when medals electronically stored in RAM 308 are inserted as medals to be inserted into a game. The settlement button 134 sensor is provided on the settlement button 134. When the settlement button 134 is pressed once, the medals electronically stored are settled. The medal payout sensor is a sensor for detecting medals to be paid out by the medal payout device 180. Note that each of the above sensors may be a non-contact sensor or a contact sensor.

[0050] The optical sensors of reel 110, reel 111, and reel 112 are installed at predetermined positions on the mounting bases of each of reels 110 to 112, and go to L level every time a light-shielding piece provided on the reel frame passes by. When CPU 304 detects this signal, it determines that the reel has made one rotation and resets the rotational position information of the reel to zero.

[0051] The main control unit 300 is equipped with a drive circuit 322 that drives the stepping motors provided in the reel devices 110 to 112, a drive circuit 324 that drives the solenoid provided in the medal selector 170 that selects the inserted medals, a drive circuit 326 that drives the motor provided in the medal payout device 180, and a drive circuit 328 that drives various lamps 336 (winning line indicator lamp 120, notification lamp 123, game medal insertion possible lamp 124, replay lamp 122, game medal insertion lamp 129, game start lamp 121, number of stored medals indicator 125, game information indicator 126, number of paid out medals indicator 127).

[0052] 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.

[0053] The main control unit 300 also includes a voltage monitoring circuit 330 that monitors the voltage value of the power supply supplied to the main control unit 300 from a power management unit (not shown), and the voltage monitoring circuit 330 outputs a low voltage signal to the basic circuit 302 indicating that the voltage has dropped when the voltage value of the power supply is below a predetermined value (9V in this embodiment).

[0054] In addition, the main control unit 300 is equipped with an output interface for sending commands to the first sub-control unit 400, enabling communication with the first sub-control unit 400. Note that information communication between the main control unit 300 and the first sub-control unit 400 is one-way communication, and the main control unit 300 is configured to be able to send signals such as commands to the first sub-control unit 400, but is configured so that signals such as commands cannot be sent from the first sub-control unit 400 to the main control unit 300.

[0055] <Sub-controller> Next, the first sub-control unit 400 of the slot machine 100 will be described. The first sub-control unit 400 includes a basic circuit 402 that receives control commands sent by the main control unit 300 via an input interface and controls the entire first sub-control unit 400 based on these control commands. This basic circuit 402 is equipped with a CPU 404, a RAM 408 for temporarily storing data, an I / O 410 for controlling the input and output of various devices, and a counter timer 412 for measuring time, number of times, etc. The CPU 404 of the basic circuit 402 operates by receiving a clock signal with a predetermined period output by a crystal oscillator 414 as a system clock. The ROM 406 stores control programs and data for controlling the entire first sub-control unit 400, data for controlling the backlight lighting pattern and various displays, etc.

[0056] 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.

[0057] The first sub-control unit 400 is also provided with a sound source IC 418, which is connected to speakers 272, 277 via an output interface. The sound source IC 418 controls the sound output from the amplifier and speakers 272, 277 in response to commands from the CPU 404. An S-ROM (sound ROM) in which sound data is stored is connected to the sound source IC 418, and the sound data acquired from this ROM is amplified by the amplifier and output from the speakers 272, 277.

[0058] In addition, the first sub-controller 400 is provided with a drive circuit 422, to which various lamps 420 (upper lamps, lower lamps, side lamps 144, title panel 162 lamps, etc.) are connected via an input / output interface.

[0059] The first sub-control unit 400 also has a drive circuit 424 that drives the motor of the shutter 163, and the drive circuit 424 is connected to the shutter 163 via an output interface. This drive circuit 424 outputs a drive signal to a stepping motor (not shown) provided in the shutter 163 in response to a command from the CPU 404.

[0060] The first sub-control unit 400 is also provided with a sensor circuit 426, which is connected via an input interface to a shutter sensor 428 capable of detecting the position of the shutter 163 and an effect button sensor 430 capable of detecting the pressing operation of the effect button 156. The CPU 404 monitors the status of the shutter sensor 428 and the effect button sensor 430 at each interrupt time.

[0061] 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).

[0062] The second sub-control unit 500 is equipped with a basic circuit 502 that receives control commands sent by the first sub-control unit 400 via an input interface and controls the entire second sub-control unit 500 based on these control commands.This basic circuit 502 is equipped with a CPU 504, a RAM 508 for temporarily storing data, an I / O 510 for controlling the input and output of various devices, and a counter timer 512 for measuring time, number of times, etc.The CPU 504 of the basic circuit 502 operates by inputting a clock signal of a predetermined period output by a crystal oscillator 514 as a system clock.The ROM 506 stores control programs and data for controlling the entire second sub-control unit 500, data for image display, etc.

[0063] 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.

[0064] The second sub-control unit 500 is also provided with a VDP 516 (video display processor), which is connected to the ROM 506 and VRAM 518 via a bus. The VDP 516 reads out image data and the like stored in the ROM 506 based on signals from the CPU 504, generates a display image using the work area of ​​the VRAM 518, and displays the image on the performance image display device 157.

[0065] <Pattern Arrangement> Next, the arrangement of symbols on the reels 110 to 112 will be described with reference to Figure 4. Figure 4 is a diagram showing the arrangement of symbols on each reel (left reel 110, center reel 111, right reel 112) in a flat layout.

[0066] On each of the reels 110 to 112, a predetermined number of symbols (20 symbols numbered 0 to 19 in this embodiment) of various types (9 symbols in this embodiment) shown on the right side of the figure are arranged. The numbers 0 to 19 shown on the left side of the figure are numbers indicating the arrangement positions of the symbols on each of the reels 110 to 112. For example, in this embodiment, a "watermelon symbol" is arranged on the symbol number 0 on the left reel 110, a "bell symbol" is arranged on the symbol number 1 on the center reel 111, and a "replay symbol" is arranged on the symbol number 0 on the right reel 112.

[0067] <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.

[0068] The winning combinations of the slot machine 100 include special combinations (special combination 1, special combination 2) and general combinations (replay combinations 1 to 3, small combinations 1 to 5). The types of winning combinations are not limited to these combinations and can be arbitrarily adopted, and some of the winning combinations are not shown in FIG. 5.

[0069] <Types of winning roles / special roles> Among the winning combinations in this embodiment, special combination 1 and special combination 2 are combinations that transition to a special game state in which a predetermined benefit is awarded to the player. Also, the replay combination is a combination that allows replay without inserting new medals (a combination that awards replay). These winning combinations are sometimes called "operation combinations."

[0070] In addition, "winning" in this embodiment also includes cases where a pattern combination of an operating role that does not involve a medal payout (does not involve the payment of medals) is displayed on the winning line, and includes, for example, winning special role 1, special role 2, and re-play role.

[0071] Special Role 1 and Special Role 2 are winning roles that transition the game state to the Special Role 1-2 internal winning state (RT3) upon internal winning, and then transition the game state to the Special Role 1-2 game state (RT4) upon winning. In addition, if more than the specified number of medals (for example, 200 medals) are paid out in the Special Role 1-2 game state (RT4), the game state transitions to the low replay probability state (RT1). Each game state (RT1 to RT4) will be described later.

[0072] 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".

[0073] When special role 1 or special role 2 is internally won, the special role internal win flag corresponding to this internally won role is set to ON (stored in a predetermined area of ​​RAM 308 of the main control unit 300). This flag remains ON until the internally won role is won, making it easier to win that internally won role in subsequent games. In other words, in a game in which special role 1 or special role 2 is internally won, even if the special role is not won, the special role will be internally won in subsequent games, making it easier to win the symbol combination corresponding to the special role.

[0074] <Type of winning combination / replay combination> Replay roles 1 to 3 are winning roles (operating roles) that allow you to play the next game without inserting medals (game media), and medals are not paid out. The corresponding symbol combinations are as shown in Figure 5.

[0075] The replay role may be any role that allows the player to play the next game without inserting medals. Therefore, for example, when a replay role is won, medals may be automatically inserted in the next game (the number of inserted medals is reset in the medal insertion number storage area), or medals inserted in a game that wins a replay role may be carried over and used in the next game. A special replay, which will be described later, is also one type of replay role.

[0076] <Type of winning role / small role> Small winning combinations 1 to 5 are winning combinations in which a predetermined number of medals are paid out (there is a payout number).

[0077] Minor win 1 (watermelon) is a winning combination in which the symbol combination "watermelon symbol-watermelon symbol-watermelon symbol" is stopped and displayed on the winning line L1, and five medals are paid out.

[0078] Minor win 2 (Cherry) is a winning combination in which the symbol combination "Cherry symbol-ANY-ANY" is stopped and displayed on the winning line 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.

[0079] Hereinafter, these small prizes 1 (watermelon) and 2 (cherry) may be collectively referred to as "rare prizes", but rare prizes are not limited to these winning prizes, and may be either one of the winning prizes, or may include other winning prizes.

[0080] In addition, if you win a rare role in the AT state described below, a lottery to add the number of games or the number of sets will be executed (making it easier to win the lottery). On the other hand, even if you win a rare role in the ED state, a lottery to add the number of games or the number of sets will not be executed.

[0081] The small prize 3 (push order bell) is composed of six types of winning combinations, small prize 3a to small prize 3f. In this example, by lottery, with a predetermined probability (in this example, about 1 / 6. Common to all settings), one of the winning combinations of 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 corresponding winning combination 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 combination) whose advantage varies depending on the operation mode of the stop buttons (stop buttons) 137 to 139.

[0082] Minor win 4 (common bell) is a winning combination in which the pattern combination of "bell symbol-bell symbol-bell symbol" is displayed stopped on the winning line L1, regardless of the order (press order) or timing of the stop operations using stop buttons 137 to 139, and 12 medals are paid out.

[0083] The small combination 5 (a 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.

[0084] <Types of RT-based game states> Next, the types and transitions of RT-based game states in the slot machine 100 will be described.

[0085] <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 of the slot machine 100 is turned on, etc., and is a game state that is relatively disadvantageous for the player compared to other game states

[0086] In this example, in this replay low probability state (RT1), when winning the replay combination 2 (upgraded replay 1) or the 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 the special combination 2, it transitions to the special combination 1·2 internal winning state (RT3) described later.

[0087] <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).

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

[0089] <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.

[0090] 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.

[0091] <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 re-gaming state (RT1).

[0092] 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 in a specified role, when there are winnings a specified number of times (for example, 8 times), or when a specified number of games (for example, 6 times) are played.

[0093] <Transition of AT-based gaming states> Next, the AT-based gaming states will be described.

[0094] 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.

[0095] Here, the operation navigation refers to an effect that notifies the stop operation mode (for example, the correct operation order or 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 a pressing order role (for example, small role 3 (pressing order bell LCR)) (for example, an effect that displays the characters "left → middle → right") etc. corresponds to this.

[0096] When a player performs a stop operation according to the operation content of the operation navigation, the result is advantageous to the player, so the high navigation state is a gaming state that is more advantageous to the player than the low navigation state. Here, advantageous specifically means that the ratio of the total number of gaming media paid out by the gaming machine to the total number of gaming media used by the player as the number of bets on the gaming machine when playing for a predetermined period of time, that is, the so-called payout rate (ball payout rate), is advantageous.

[0097] In this example, the low navigation state is defined as a state in which the probability of operation navigation being executed is low, and the high navigation state is defined as a state in which the probability of operation navigation being executed is higher than in the low navigation state. However, the low navigation state may also be defined as a state in which operation navigation is not executed, and the high navigation state as a state in which operation navigation is executed.

[0098] Each game state of the AT system is subdivided and managed, and these are called presentation states. In detail, the presentation state of the low navigation state is the normal game state, and the presentation state of the high navigation state includes the normal state, the confirmation notification state, the judgement state, the pullback state, the AT1 state, the AT2 state, and the ED (ending) state. In principle, the AT1 state, the AT2 state, and the ED state are states in which the number of balls released increases.

[0099] In this embodiment, when a certain condition is met in the normal game state in the low navigation state (for example, when a winning combination other than a miss is won), the game transitions to the normal state in the high navigation state. After that, for example, the game transitions in the order of the confirmation notification state → AT1 state → judgement state, and from this judgement state, there is a route to transition to the normal game state or AT2 state via the pull-back state, or a route to transition directly from the judgement state to the AT2 state.

[0100] The AT state (AT1 state, AT2 state) is a state in which AT play is possible a predetermined number of times (for example, 30 games per set), and is a state that is more advantageous for the player than the normal play state in a low navigation state or the normal state in a high navigation state.

[0101] In this AT game, at the start of the AT game, a set continuation lottery (for example, a lottery with a 1 / 4 probability of winning) is held to determine whether or not to continue the AT game, and if the set continuation lottery is won, a predetermined number of AT games (in this example, one set of 30 games) are awarded, and the AT state is extended. Also, if the conditions for transitioning to the normal game state are met in the AT state (in this example, when all games in the AT state have been played), the game will transition to the normal game state from the next game.

[0102] Also, when the number of remaining games in the high navigation state falls below a predetermined number (for example, 20 games), the state transitions to an ED state, and in this ED state, an ED (ending) effect is executed, indicating the end of the high navigation state.

[0103] The condition for transitioning to the ED state is not limited to the number of remaining games in the high navigation state being less than a predetermined number of games (for example, 20 games), but may be, for example, that the predetermined number of games is more or less than 20 games, or that "number of coins won + expected difference in number of coins won > 2000".

[0104] <Main processing of main control unit> 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. This figure is a flowchart showing the flow of the main control unit main processing.

[0105] As described above, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 338 that outputs a start signal (reset signal) when power is turned on. When this start signal is input, the CPU 304 of the basic circuit 302 is reset and started by a reset interrupt, and executes the main processing of the main control unit shown in FIG. 6 in accordance with a control program previously stored in the ROM 306.

[0106] When the power is turned on, first, various initial settings are performed in step S101. These initial settings include setting a stack initial value to the stack pointer (SP) of the CPU 304, setting interrupt prohibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, and setting operation permission and initial values ​​for the WDT 314.

[0107] In step S102, a bet number setting / start operation acceptance process is executed. Here, whether or not medals have been inserted is checked, and preparations are made to send an insertion command indicating that medals have been inserted. If a replay role was won in the previous game, a process is performed to insert the same number of medals as the number inserted in the previous game, eliminating the need for the player to insert medals. Also, a check is made to see if the start lever 135 has been operated, and if the start lever 135 has been operated, the process proceeds to step S103.

[0108] In step S103, the number of inserted medals is determined, and a win line determination process is performed to determine the valid win lines.

[0109] In step S104, the random number generated by the random number generating circuit 316 is obtained, and a winning combination internal lottery process is performed. In the winning combination internal lottery process, the winning combination lottery table stored in ROM 306 is read out according to the current game state, and an internal lottery is performed using this and the obtained random number value, and preparations are made to send an internal lottery command indicating the result of this internal lottery to the first sub-control unit 400. If any winning combination (including an operating combination) is internally won as a result of the internal lottery, the flag for that winning combination is turned on.

[0110] In step S105, a reel stop data selection process is performed to select reel stop data based on the internal lottery result of the winning combination internal lottery process. This reel stop data is stored in the ROM 306 of the main control unit 300. In step S105, preparations are made to send a reel stop data command containing information about the selected reel stop data to the first sub-control unit 400.

[0111] In step S106, a presentation state control process for controlling the game state of the AT system is executed based on the start lever operation. In step S107, a presentation process is executed. In this presentation process, various presentations are controlled.

[0112] In step S108, a reel rotation start process is executed, and all the reels 110 to 112 start rotating.

[0113] In step S109, a reel stop control process is performed. In the reel stop control process, the stop buttons 137 to 139 can be accepted, and when one of the stop buttons is pressed, a stop table of reel stop data is referenced to stop the reel corresponding to the pressed stop button, and one of the reels 110 to 112 is stopped according to the number of reel pull-in frames set in the stop table. When all the reels 110 to 112 have stopped, the process proceeds to step S110. In this step S109, for each stop operation, preparations are made to send to the first sub-control unit 400 a stop button acceptance command (more specifically, a stop button acceptance 1 command for the first stop operation, a stop button acceptance 2 command for the second stop operation, and a stop button acceptance 3 command for the third stop operation) relating to the stop button 137 to 139 that was operated to stop, and for each reel stop, preparations are made to send to the first sub-control unit 400 a reel stop command (more specifically, a reel stop 1 command for the first stopped reel, a reel stop 2 command for the second stop operation, and a reel stop 3 command for the third stop operation) relating to the reel stop position.

[0114] In step S110, a winning determination process is performed to determine whether a player has won a prize. In this winning determination process, if a symbol combination corresponding to a winning role is displayed on the activated winning line 114, it is determined that the player has won that winning role. For example, if "Bell-Bell-Bell" is lined up on the activated winning line, it is determined that the player has won minor role 3 (Bell). In addition, in this step S110, preparations are made to send a winning determination command indicating the result of the winning determination to the first sub-control unit 400.

[0115] 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.

[0116] In step S112, a game state control process is performed. In the game state control process, processing related to the transition of each game state of the RT system is performed, and the game state is transitioned when the start condition or end condition is met. In addition, preparations are made to send a game state command including information indicating the current game state of the RT system.

[0117] In step S113, the controller 100 executes a performance state control process for controlling the game state of the AT system described above. In step S114, the controller 100 executes a high-level navigation state termination process for terminating the high-level navigation state.

[0118] This completes one game. After that, the game progresses by returning to step S102 and repeating the above-mentioned process. The various commands prepared in the above steps are transmitted in the command setting and transmission process (step S206 in FIG. 7) of the main control unit timer interrupt process, which will be described later.

[0119] <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. The figure is a flowchart showing the flow of the main control unit timer interrupt process.

[0120] 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.

[0121] 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.

[0122] In step S202, WDT314 is restarted periodically (in this embodiment, once every 2 ms, which is the period of the main control unit timer interrupt) to prevent the count value of WDT314 from exceeding the initial setting value (32.8 ms in this embodiment) and causing a WDT interrupt (to prevent processing abnormalities from being detected).

[0123] In step S203, an input port state update process is performed. In this input port state update process, detection signals from the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310, and the presence or absence of the detection signals is monitored and stored in signal state storage areas partitioned for each of the various sensors 318 in the RAM 308.

[0124] In step S204, various game processes are executed, and processes according to the interrupt status are executed. In step S2005, timer update processing is performed. More specifically, various timers are updated in their respective time units.

[0125] In step S206, a command setting transmission process is performed, and various commands that have been prepared for transmission are transmitted to the first sub-control unit 400. The first sub-control unit 400 is able to determine the presentation control in response to changes in game control in the main control unit 300 based on the command type contained in the received output schedule information, and is also able to determine the content of the presentation control based on the command data information contained in the output schedule information.

[0126] 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.

[0127] In step S208, device monitoring processing is performed. In this device monitoring processing, first, the signal states of the various sensors 318 stored in the signal state storage area in step S203 are read out to monitor for errors related to medal insertion abnormalities, medal payout abnormalities, etc., and if an error is detected (not shown), error processing is executed. Furthermore, depending on the current game status, settings are made for the medal selector 170 (a medal blocker operated by a solenoid provided in the medal selector 170), various lamps 339, and various 7-segment (SEG) indicators.

[0128] In step S209, it is monitored whether the low voltage signal is on or not, and if the low voltage signal is on (if a power cutoff is detected), the process proceeds to step S211, and if the low voltage signal is off (if a power cutoff is not detected), the process proceeds to step S210.

[0129] In step S210, various processes are performed to end the timer interrupt end process. In this timer interrupt end process, the values ​​of each register temporarily saved in step S2001 are set back to the original registers. Then, the process returns to the main process of the main control unit shown in FIG.

[0130] On the other hand, in step S211, specific variables and stack pointers for restoring the state to the state at the time of power outage when power is restored are saved as recovery data in a predetermined area of ​​RAM 308, power outage processing such as initialization of input / output ports is performed, and then the process returns to the main processing of the main control unit shown in Figure 7.

[0131] <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.

[0132] First, the main processing of the first sub-control unit 400 will be described with reference to FIG. 8(a).

[0133] When the power is turned on, an initialization process is first executed in step S301. In this initialization process, the input / output ports are initially set up, and a storage area in RAM 408 is initialized. In this process, an area for storing internal win information, which is information showing the result of an internal win, and an area for storing RT update information, which is information showing the game status, are provided in RAM 408.

[0134] In step S302, it is determined whether the timer variable is 10 or greater, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or greater, the process proceeds to step S3003. In step S303, 0 is substituted into the timer variable. In step S304, command processing, which is processing corresponding to each command received from the main control unit 300, is executed.

[0135] In step S305, a performance control process is performed. Here, performance preparation is performed in accordance with the performance reservation information stored in the performance reservation area in RAM 408. This preparation includes, for example, reading performance data from ROM 406 and updating the performance data if it needs to be updated.

[0136] 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.

[0137] 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.

[0138] Next, using Figure 8(b), we will explain the command reception interrupt processing of the first sub-control unit 400. This command reception interrupt processing is processing that the first sub-control unit 400 executes when it detects a strobe signal output by the main control unit 300. In step S401 of the command reception interrupt processing, the command output by the main control unit 300 is stored as an unprocessed command in a command memory area provided in RAM 408.

[0139] 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 this timer interrupt triggers the timer interrupt processing to be executed at a predetermined period.

[0140] 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 value of the timer variable is determined to be 10 or greater every 20 ms (2 ms x 10). In step S502, commands are sent to the second sub-control unit 500 set in step S309, and the random number value for presentation is updated, etc.

[0141] <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.

[0142] First, in step S601 of Fig. 9(a), various initial settings are performed. When the power is turned on, initialization processing is first executed in step S601. This initialization processing includes initial setting of input / output ports, initialization processing of storage areas in RAM 508, initialization processing of storage areas in VRAM 536, etc.

[0143] In step S602, it is determined whether the timer variable is greater than or equal to 10, and this process is repeated until the timer variable becomes greater than or equal to 10. When the timer variable becomes greater than or equal to 10, the process proceeds to step S603. In step S4003, 0 is assigned to the timer variable. In step S604, command processing is performed. In command processing, the CPU 504 of the second sub-control unit 500 determines whether a command has been received from the CPU 404 of the first sub-control unit 400.

[0144] In step S605, effect control processing is performed. Specifically, if a new command is received in step S604, processing corresponding to this command is performed. For example, processing is executed to read effect data for image control related to the background image from ROM 506. In addition, processing is executed to read other effect data from ROM 506, and if the effect data needs to be updated, processing to update the effect data is also executed.

[0145] In step S606, image control processing (described in detail below) is performed based on the processing result of step S605. For example, if the performance data read in step S605 contains an image control command, image control corresponding to this command is performed. For example, image control related to the display image (announcement image, background image) is executed. When this image control processing is completed, the process returns to step S602.

[0146] Next, using Figure 9(b), we will explain the command reception interrupt processing of the second sub-control unit 500. This command reception interrupt processing is processing that the second sub-control unit 500 executes when it detects a strobe signal output by the first sub-control unit 400.

[0147] In step S701 of the command reception interrupt processing, the command output by the first sub-control unit 400 is stored in a command storage area provided in the RAM 508 as an unprocessed command.

[0148] 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 this timer interrupt triggers the execution of the timer interrupt processing at a predetermined period.

[0149] 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, processing such as updating the random number value for presentation is performed.

[0150] Next, the image control processing of step S606 in the main processing of the second sub-control unit 500 will be described with reference to Figure 9(d). This figure is a flowchart showing the flow of the image control processing.

[0151] In step S901, an instruction to transfer image data is issued. Here, the CPU 504 first swaps the designation of the drawing areas of display area A and display area B of the VRAM 536. As a result, one frame of image stored in a display area not designated as a drawing area is displayed on the performance image display device 157. Next, the CPU 504 sets ROM coordinates (source address in ROM 506), VRAM coordinates (destination address in VRAM 536), etc. in the attribute register of the VDP 534 based on the position information table, and then sets a command to start transferring image data from ROM 506 to VRAM 536. The VDP 534 transfers the image data from ROM 506 to VRAM 536 based on the command set in the attribute register. Thereafter, the VDP 534 outputs a transfer end interrupt signal to the CPU 504.

[0152] 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.

[0153] In step S903, parameters are set based on the rendering scenario configuration table, attribute data, etc. Here, CPU 504 instructs VDP 534 on information about the image data that constitutes the display image (coordinate axes of VRAM 536, image size, VRAM coordinates (placement coordinates), transparency, etc.) in order to form a display image in display area A or B of VRAM 536 based on the image data transferred to VRAM 536 in step S901. VDP 534 sets parameters in accordance with the attributes based on the command stored in the attribute register.

[0154] 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.

[0155] In step S905, it is determined whether a generation completion interrupt signal has been input from VDP 534 based on the completion of image drawing. If a generation completion interrupt signal has been input, the process proceeds to step S906; if not, the process waits for the generation completion interrupt signal to be input.

[0156] 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.

[0157] <Speaker mounting structure> Next, the speaker mounting structure in the slot machine 100 will be described.

[0158] FIG. 10 is a front view showing the slot machine 100 with the front door 102 open. The main body 101 is a box-shaped body surrounded by a top panel 261, a left side panel 260, a right side panel 260, a bottom panel 264, and a back panel 242, and is open at the front. Inside the main body 101, a main control board storage case 210 storing a main control board is disposed in a position that does not overlap with the ventilation opening 249 provided at the top of the back panel 242, and three reels 110 to 112 are disposed below this 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 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.

[0159] A medal payout device 180 (a device that pays 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, with a power switch 244 disposed on the front of the power supply device 252. The power supply device 252 converts AC power supplied from an external source to the slot machine 100 into DC, converts it into a predetermined voltage, and supplies it to each control unit and device, such as the main control unit 300 and sub-control units 400 and 500, which will be described later. Furthermore, the power supply device 252 is provided with a power storage circuit (e.g., a capacitor) for supplying power to predetermined components (e.g., the RAM 308 of the main control unit 300) for a predetermined period (e.g., 10 days) even after the external power supply is cut off.

[0160] An auxiliary medal storage 240 is disposed on the right side of the medal payout device 180, and an overflow terminal (not shown) is disposed behind this. 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.

[0161] 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 symbol 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 symbol display window 113 are provided a medal selector 170 for sorting inserted medals, and a passage 266 through which medals pass when the medal selector 170 drops illegal medals and the like into the medal tray 161. Furthermore, a speaker unit 600 is provided at a position corresponding to the sound hole 181.

[0162] <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.

[0163] 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 member) for low-frequency output having a large diaphragm and a back cover 620 (second member) that covers the back side of this speaker 610, and is attached to a speaker pedestal 630 (base) formed on the back surface of front door 102.

[0164] <Speaker mounting structure / speaker base> Speaker base 630 (base) comprises an outer frame 631 formed to fit the roughly rectangular outer shape of flange 614 of speaker 610, mounting sleeves 632 formed at each of the four inner corners of outer frame 631 for screwing speaker 610 and rear cover 620 to front door 102, and a circular inner frame 633 against which the front peripheral edge of frame 612 of speaker 610 abuts.

[0165] A sound hole 161 consisting of multiple holes is formed inside the inner frame portion 633 of the speaker base 630, and the low-pitched sounds output from the speaker 610 are output to the outside of the slot machine 100 through this sound hole 161.

[0166] <Speaker mounting structure / speaker, rear cover> Next, the speaker 610 and rear cover 620 that constitute the speaker unit 600 will be described in detail with reference to FIGS.

[0167] 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 of speaker unit 600 shown in Fig. 13(a) taken along line AA.

[0168] <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 generally composed of an electromagnetic circuit 611 that consists of a voice coil and a magnet and vibrates diaphragm 613 (described later) in response to an electric signal, a frame 612 that supports electromagnetic circuit 611, diaphragm 613 that vibrates to generate sound, and a flange 614 to which diaphragm 613 is fixed so that it can vibrate.

[0169] 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 its side to allow air to escape around diaphragm 613. That is, a plurality of openings 615 are formed in the circumferential direction on the side of frame 612, and struts 612a are formed in the front-to-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.

[0170] 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 and lower right corners of the flange 614. Also, shared screw holes 616b (second through holes) for screwing the speaker 610 and rear cover 620 to the front door 102 are formed in the lower left and upper right corners of the flange 614.

[0171] 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 periphery of the flange 614.

[0172] 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.

[0173] The positions and numbers of the "first through hole" and "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 in only one of the upper left corner or lower right corner on the outer edge of the flange 614, and one common screw hole 616b (second through hole) may be arranged in only one of the lower left corner or upper right corner on the outer edge of the flange 614. Furthermore, 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 numbers of dedicated screw holes 616a (first through holes) and common screw holes 616b (second through holes) do not have to be the same.

[0174] Flange 614 also functions as a member that supports diaphragm 613 so that it can vibrate, and outer edge 613a (see FIG. 13(b)) of diaphragm 613, which passes through the opening of flange 614 and appears on the back side of flange 614, is fixed to the back side of flange 614. The thickness of flange 614 is designed to be greater than the maximum vibration amplitude of diaphragm 613 so as not to inhibit the vibration of diaphragm 613.

[0175] In this example, rear cover 620 is placed on the rear of speaker 610, and when rear cover 620 is fixed to speaker base 630 of front door 102, the minimum distance between rear cover 620 and front door 102 is designed to be longer than the thickness of flange 614 so as not to impede the vibration of diaphragm 613.

[0176] <Speaker mounting structure / rear cover> Rear cover 620 (second member) is a resin member that houses most of speaker 610. More specifically, rear cover 620 has circular opening 621 formed on the rear side that exposes 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.

[0177] 12(b), rear cover 620 has two protruding pieces 623a and two protruding pieces 623b with screw holes that 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).

[0178] With this configuration, by aligning the common 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 protruding piece 623b of the rear cover 620 with the holes in the mounting sleeve 632 of the speaker pedestal portion 630 (base) and fastening them with screws (fixing means), 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.

[0179] 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 inside thereof is formed a screw head accommodating space 623a1 that can accommodate the head (screw head) of a screw (fixing means).

[0180] With this configuration, by aligning dedicated screw holes 616a (first through holes) in flange 614 of speaker 610 with holes in mounting sleeve 632 of speaker pedestal portion 630 (base) and fastening with screws (fixing means), even when rear cover 620 is positioned relative to the rear surface of speaker 610 after only speaker 610 is fixed to the rear surface of front door 102, rear cover 620 can be attached to the rear surface of speaker 610 without protruding piece 623a of rear cover 620 interfering with the screws (fixing means) attached to dedicated screw holes 616a of speaker 610.

[0181] Furthermore, the rear cover 620 (second member) has a point-symmetric shape and can be attached to the speaker pedestal 630 (base) even when rotated 180 degrees, which makes it possible to easily attach the rear cover 620 (second member).

[0182] Box-shaped space 622S is formed to protrude from part of side wall 622, for accommodating lead wires connected to electromagnetic circuit 611 and for leading the lead wires to the outside of speaker unit 600. Side wall 622 also has a plurality of vent holes 625 formed at predetermined intervals in the circumferential direction as openings for releasing air around diaphragm 613.

[0183] <Speaker installation structure / correct installation method> Next, the correct method of mounting the speaker unit 600 will be described with reference to FIG. 14(a).

[0184] FIG. 14(a) is a diagram showing a schematic example of a correct mounting method for the speaker unit 600. In FIG.

[0185] 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 the same figure (a-2), the rear cover 620 (second member) is attached to the speaker base 630 (base).

[0186] 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 the speaker pedestal part 630 (base) and fastened with screws 634 (fixing means), thereby attaching only the speaker 610 to the speaker pedestal part 630 (base).

[0187] Next, rear cover 620 is positioned relative to speaker base 630 (base) so that it covers the rear surface of speaker 610. However, 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, so that rear cover 620 can be reliably positioned on the rear surface of speaker 610 as shown in FIG. 14(a-2).

[0188] Finally, with rear cover 620 positioned on the rear surface of speaker 610, screw holes 624 (third through holes) in screw-hole protrusion 623b of rear cover 620 are aligned with two shared screw holes 616b (second through holes) in flange 614 of speaker 610 and with holes in mounting sleeve 632 of speaker pedestal 630 (base), and then fastened with screws 634 (fixing means), thereby attaching rear cover 620 to speaker pedestal 630 (base). As a result, speaker unit 600 is integrated and fixed to the rear surface of front door 102.

[0189] According to this example, when fixing the speaker 610 (first member) and the rear cover 620 (second member) to the speaker pedestal 630 (base) with screws (fixing means), they can be fixed at once with one screw 634 (fixing means) via the shared 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), which simplifies the work of attaching the members compared to conventional methods. Also, after the speaker 610 (first member) is fixed and positioned on the base using the dedicated screw hole 616a (first through-hole), the rear cover 620 (second member) can be fixed to the speaker pedestal 630 (base). This eliminates the need to position the two members simultaneously, improving work efficiency.

[0190] 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 carried out reliably.

[0191] The rear cover 620 (second member) has a point-symmetric shape and can be attached to the speaker pedestal 630 (base) even when rotated 180 degrees, which makes it easier to attach the rear cover 620 (second member).

[0192] <Speaker installation structure / incorrect installation method> Next, an incorrect method of mounting the speaker unit 600 will be described with reference to FIG. 14(b).

[0193] FIG. 14(b) is a diagram showing a schematic example of an incorrect installation method for the speaker unit 600.

[0194] 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 part 630 (base) instead of the two dedicated screw holes 616a (first through holes), and the speaker 610 alone is attached to the speaker pedestal part 630 (base) by fastening with screws 634 (fixing means).

[0195] 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 mistakenly 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.

[0196] According to this example, it is possible to easily recognize that the speaker 610 (first member) has been attached in an incorrect manner, and to prevent work errors from occurring.

[0197] 15(a) and 15(b) are diagrams showing another example of an incorrect mounting method for the speaker unit 600. In FIG.

[0198] The example shown in Figure 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.

[0199] 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 speaker 610 (first member) has been attached in an incorrect manner, and work errors can be prevented in advance.

[0200] The example shown in FIG. 15(b) is an example in which the rear cover 620 (second member) is mistakenly rotated by 90 degrees and an attempt is made to position it relative to the speaker pedestal 630 (base).

[0201] 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 because it does not have an axisymmetric shape, it cannot be positioned relative to the speaker base 630 (base) when rotated 90 degrees.

[0202] Furthermore, because 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 rear cover 620 (second member) has been attached incorrectly, and work errors can be prevented in advance.

[0203] <Speaker mounting 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 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 formed by one or more 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.

[0204] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base with the fixing means, they can be fixed at once with one fixing means via the second through-hole of the first member and the third through-hole of the second member, which simplifies the work of attaching the members compared to conventional systems. Also, since the second member can be fixed to the base after the first member has been fixed and positioned to the base using the first through-hole, there is no need to position the two members simultaneously, which improves work efficiency.

[0205] It should be noted that the "first member" and "second member" according to the present invention are not limited to a speaker and a back cover, but 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."

[0206] Furthermore, after the first member is fixed to the base using the first through hole, when 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.

[0207] With this configuration, it is possible to visually confirm that it is not necessary to use the first through-hole when fixing the second member, and the member mounting work can be carried out reliably.

[0208] Furthermore, 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 circumferential direction of the first member.

[0209] 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.

[0210] In addition, 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, and the plurality of first through holes may be located at diagonal positions on the first member, and the plurality of second through holes may be located at diagonal positions on the first member.

[0211] Furthermore, when the first member is fixed to the base with a fixing means (e.g., screw 634 shown in Figure 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.

[0212] With this configuration, it is possible to easily recognize that the first member has been attached in an incorrect manner, and to prevent operational errors before they occur.

[0213] Furthermore, 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 610 shown in FIGS. 11 and 14) that can be fixed to a base (for example, the speaker base 630 of the front door 102 shown in FIG. 11) and a second member (for example, the rear cover 620 shown in FIGS. 11 and 14) that can cover at least a part of the first member, wherein the first member has a plurality of first through holes and a plurality of second through holes different from the first through holes, the second member has a plurality of third through holes, the first through holes are through holes used to fix the first member of the first and second members to the base, the second through holes and the third through holes are through holes used to fix both the first member and the second member 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.

[0214] Furthermore, 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 610 shown in FIG. 11 or 14) that can be fixed to a base (for example, the speaker base 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, wherein the first member has a plurality of first through holes and a plurality of second through holes different from the first through holes, the second member has a plurality of third through holes, and the first through holes are formed between the first member and the second member. The gaming machine is characterized in that the first through hole is a through hole used to fix the first member to the base, the second through hole and the third through hole are through holes used to fix 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 are configured so that when the multiple first through holes and the second through holes on either side of the multiple first through holes are connected by straight lines, a rectangle is formed, and the multiple first through holes are arranged on the diagonals of the rectangle (the vertices at the ends of the diagonals).

[0215] Furthermore, 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 610 shown in FIG. 11 or 14) that can be fixed to a base (for example, the speaker base 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 first through holes and a plurality of second through holes different from the first through holes, and the second member has a plurality of third through holes. a first through hole that is used to fix the first of the first and second members to the base, the second through hole and the third through hole that are used to fix both the first and second members to the base, the first through holes and the second through holes that are alternately arranged on the outer periphery of the first member, and the base having a frame portion formed to match the outer shape of the first member.

[0216] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base with the fixing means, they can be fixed at once with one fixing means via the second through-hole of the first member and the third through-hole of the second member, which simplifies the work of attaching the members compared to conventional systems. Also, since the second member can be fixed to the base after the first member has been fixed and positioned to the base using the first through-hole, there is no need to position the two members simultaneously, which improves work efficiency.

[0217] <Speaker mounting structure (variation 1) / speaker unit configuration> Next, the configuration of speaker unit 700 according to Modification 1 will be described with reference to Fig. 16. Fig. 16 is an exploded perspective view of speaker unit 700 according to Modification 1.

[0218] As shown in FIG. 16, the speaker unit 700 of the first variant is composed of a speaker 710 (first member) for outputting low frequencies 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 730 (base) formed on the back surface of the front door 102 of the slot machine.

[0219] <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 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 731. The detailed configuration of the speaker pedestal 730 (base) will be described later using FIG. 19.

[0220] <Speaker mounting structure (variation 1) / speaker, rear cover> Next, the speaker 710 and rear cover 720 that constitute the speaker unit 700 according to the first modification will be described in detail with reference to FIGS.

[0221] Fig. 17(a) is a side view of the rear cover 720, and Fig. 17(b) is a top view of the rear cover 720. Also, Fig. 17(c) is a side view of the speaker 710, and Fig. 17(d) is a top view of the speaker 710. Also, Fig. 18(a) is a top view of the speaker unit 700, and Fig. 18(b) is a cross-sectional view of the speaker unit 700 shown in Fig. 18(a) taken along line BB.

[0222] <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 of the flange 714 when viewed from above, and lead wires (wiring) 717 detachably connected to the lead terminals 716.

[0223] 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 its side to allow air to escape around diaphragm 713. That is, a plurality of openings 715 are formed in the circumferential direction on the side of frame 712, and struts 712a (see FIG. 16) are formed in the front-to-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.

[0224] 17(d), dedicated screw holes 716a (first through holes) for screwing the speaker 710 to the speaker pedestal 730 (base) are formed in the upper left and lower right corners of the outer edge of the flange 714. Also, shared screw holes 716b (second through holes) for screwing the speaker 710 and rear cover 720 to the speaker pedestal 730 (base) are formed in the lower left and upper right corners of the outer edge of the flange 714.

[0225] 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 in the circumferential direction along the outer edge of the flange 714.

[0226] In other words, as shown in Figure 17(d), when a plurality of dedicated screw holes 716a (first through holes) and the common screw holes 716b (second through holes) on either side of these dedicated screw holes 716a (first through holes) are connected by a virtual straight line VL, a virtual rectangle VQ is formed, and the plurality of dedicated screw holes 716a (first through holes) are arranged on the diagonals of the virtual rectangle VQ (the vertices at the ends of the diagonal), and the plurality of common screw holes 716b (second through holes) are arranged on the diagonals of the virtual rectangle VQ (the vertices at the ends of the diagonal).

[0227] Furthermore, when attention is paid to the distance between the dedicated screw hole 716a (first through hole) and the common 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 common screw holes 716b (second through holes) (for example, the common 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 common screw holes 716b (second through holes) (for example, the common screw hole 716b located in the lower left corner) are approximately the same.

[0228] 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.

[0229] <Speaker mounting structure (variation 1) / rear cover> Next, the rear cover 720 (second member) will be described in detail.

[0230] 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 seen from the outside when the speaker 710 (first member) is housed inside.

[0231] 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), the positional relationship between the speaker 710 (first member) and the rear cover 720 (second member), and the like can be visually confirmed, thereby improving the convenience of the member installation work.

[0232] 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.

[0233] As shown in Figures 17(a) and (b), the rear cover 720 has a circular cover portion 721 formed on the rear side that covers the rear end of the speaker 710, and has a cylindrical side wall portion 722 that widens slightly toward the rear, with this cover portion 721 as its base end.

[0234] Cover portion 721 has a plurality of rectangular ventilation holes 725 formed therein, which are openings for allowing air around electromagnetic circuit 711 of speaker 710 to escape, and also has predetermined markings 726 (in this example, a part number and material) printed on the upper side when viewed from the top. There are no particular limitations on the manner in which predetermined markings 726 are printed, but in this example, a part number marking indicating the part number of rear cover 720 (in this example, the character string "SPxxxx") and a material marking indicating the material of rear cover 720 (in this example, the character string "PC") are engraved on the surface of cover portion 721.

[0235] According to this example, a predetermined marking 726 is provided on the rear cover 720, and therefore 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.

[0236] As shown in FIG. 17(b), the rear cover 720 has two protruding pieces 723a and two protruding pieces 723b with screw holes that protrude outward from the outer edge of the side wall portion 722.

[0237] 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 the 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 the 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 the side wall portion 722.

[0238] In other words, as shown in Figure 17(b), when the vertices of the multiple protrusions 723a and the protrusions 723b with screw holes on either side of these multiple protrusions 723a are connected by an imaginary straight line VL2, an imaginary rectangle VQ2 is formed, and the multiple protrusions 723a are arranged on the diagonals of the imaginary rectangle VQ2 (the vertices at the ends of the diagonals), and the multiple protrusions 723b with screw holes are arranged on the diagonals of the imaginary rectangle VQ2 (the vertices at the ends of the diagonals).

[0239] The screw-hole protrusions 723b, which are arranged diagonally (at the vertices of the ends of the diagonal) at the lower left and upper right corners, have screw holes 724 (third through holes) for integrating the speaker 710 and rear cover 720 and screwing them to the speaker base 730 (base), each formed in a position slightly off-center toward the cover portion 721 (toward the center of the rear cover 720) from the center of the screw-hole protrusions 723b.

[0240] With this configuration, 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 pedestal portion 730 (base) with screws 740 (fixing means; see FIG. 16), the speaker unit 700 is integrated and fixed to the speaker pedestal portion 730 (base). The method of attaching the speaker unit 700 will be described later.

[0241] Around the screw hole 724 (third through hole) in the screw hole protruding piece 723b, there is formed a thin screw hole identification recess 724a which is an annular recess having an outer diameter larger than that of the screw hole 724. Because of the screw hole identification recess 724a formed around the screw hole 724, the thickness of the rear cover 720 around the screw hole 724 (third through hole) is made thinner than the thickness of other parts of the rear cover 720.

[0242] 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 thin.

[0243] Furthermore, the side wall portion 722 is formed with a screw hole identification groove 722a, which is a linear groove that communicates with the screw hole identification recess 724a and extends from the bottom to the top of the side wall portion 722.

[0244] 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).

[0245] According to this example, at least one of the dedicated screw holes 716a (first through holes), the shared screw holes 716b (second through holes), and the screw holes 724 (third through holes) (in this example, the screw holes 724 (third through holes)) is configured to be identifiable, so it is easy to determine whether each through hole is a through hole used to fasten only the first member to the base or a through hole used to fasten both the first member and the second member to the base, thereby improving the efficiency of the member installation work. Furthermore, the through hole type can be used as a clue to easily identify the correct orientation (installation direction) of the rear cover 720, improving convenience when installing the rear cover 720, etc.

[0246] In this example, as a configuration for making screw hole 724 (third through hole) identifiable, an example is shown in which screw hole identification recess 724a and screw hole identification groove 722a are formed near screw hole 724 (third through hole), but the present invention is not limited to this, and 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 affixed 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.

[0247] Furthermore, a part that allows the screw hole 724 (third through hole) to be identified may be formed on 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.

[0248] Furthermore, although a configuration has been exemplified in which the screw hole 724 (third through hole) of the rear cover 720 can be identified, 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.

[0249] Therefore, for example, a portion that allows at least one of the dedicated screw hole 716a (first through hole), the common 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 pedestal 730 (base), a sticker or the like that allows at least one of the through holes to be identified may be attached, or at least one of the through holes may be marked, printed, engraved, or the like that allows at least one of the through holes to be identified, or the front of the speaker 710 (first member) may be provided with a label or a stamp. The flange 714 may be formed with a portion that allows the dedicated screw hole 716a (first through hole) and / or the common 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 common screw hole 716b (second through hole) to be identified may be attached, or the dedicated screw hole 716a (first through hole) and / or the common 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 common screw hole 716b (second through hole) to be identified.

[0250] Furthermore, by making the shape of the protruding piece 723b with the screw hole of the rear cover 720 different from the shape of the protruding piece 723a, it may be possible to identify that the through hole formed in the protruding piece 723b with the screw hole is a 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 the screw hole, it may be possible to identify that the through hole of the speaker 710 covered by the protruding piece 723a is a through hole used when fixing only the speaker 710 (first member) to the speaker base part 730 (base).

[0251] 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.

[0252] 17(a), protruding pieces 723a arranged diagonally at the upper left and lower right corners of rear cover 720 (vertices at the ends of the diagonal) are thick, two-stepped portions that are taller from the bottom surface of rear cover 720 than protruding piece 723b with screw hole. Inside protruding piece 723a, screw accommodating space 723a1 is formed that is large enough to accommodate a part (head) of screw 740.

[0253] With this configuration, by fastening dedicated screw holes 716a (first through holes) of speaker 710 to speaker base portion 730 (base) with screws 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 heads of screws 740 attached to dedicated screw holes 716a of speaker 710 are accommodated in screw accommodating spaces 723a1, so that screws 740 do not interfere with rear cover 720 and rear cover 720 can be reliably attached to the rear surface of speaker 710.

[0254] Furthermore, the rear cover 720 (second member) has a point-symmetric shape and can be attached to the speaker pedestal 730 (base) even when rotated 180 degrees, which makes it possible to easily attach the rear cover 720 (second member).

[0255] 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 so that the side with predetermined markings 726 is facing up and the predetermined markings 726 are easily visible; however, even if rear cover 720 is rotated 180 degrees from the correct orientation, the direction of predetermined markings 726 will be reversed, but it will still be possible to attach it to speaker base 730 (base).

[0256] As shown in Figure 17(b), box-shaped spaces 722S (space portions) are 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.

[0257] 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 part 722 as a base end to near the lower part of the side wall part 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).

[0258] 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 drawn out to the outside of the speaker 710 (first member) and the rear cover 720 (second member) through this space.

[0259] According to this example, even if a portion of the speaker 710 (first member) is covered by the rear cover 720 (second member), the lead wire 717 (wiring) of the speaker 710 (first member) can be drawn out to the outside, thereby increasing the degree of freedom in design.

[0260] Furthermore, when fixing the rear cover 720 (second member) to the speaker base 730 (base), a wide area can be secured other than the area where the speaker base 730 (base) and the rear cover 720 (second member) come into contact (around the through-hole), thereby preventing the wiring from getting caught between the speaker base 730 (base) and the rear cover 720 (second member).

[0261] Furthermore, 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 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 and getting in the way of the installation work.

[0262] In this example, two box-shaped spaces (spaces) 722S are formed in rear cover 720, but the number of box-shaped spaces (spaces) 722S is not limited to this example, and if speaker 710 has only one lead terminal, only one box-shaped space (space) 722S that can accommodate this lead terminal may be formed. Also, a notched recess or the like may be formed below box-shaped space (space) 722S to lead a lead wire to the outside.

[0263] <Speaker mounting structure (variation 1) / speaker base> Next, the speaker pedestal 730 (base) will be described in detail with reference to FIG.

[0264] 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.

[0265] As explained using Figure 16, the speaker base 730 (base) is composed of an annular 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.

[0266] As shown in Figure 19(a), the sound hole plate 734 has multiple circular sound holes 734a formed therein 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 the outer edge of the sound hole plate 734 at predetermined intervals along the circumferential direction.

[0267] On the other hand, four sound hole plate locking portions 736, which can lock onto the locking portions 734b of the sound hole plate 734, are formed at predetermined intervals along the inner periphery of the frame support portion 731 on the inside of the frame support portion 731. Also, the height of the frame support portion 731 (height from the back surface of the front door 102) is designed to be higher than the maximum vibration amplitude of the diaphragm 713 of the speaker 710 so as not to inhibit the vibration of the diaphragm 713.

[0268] The sound hole plate 734 has an outer diameter smaller than the inner diameter of the frame support part 731, and after being 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).

[0269] Of the four mounting sleeves 732, the first mounting sleeves 732a, which are located at the upper left and lower right corners when viewed from above, are mounting sleeves to which dedicated screw holes 716a (first through holes) of the speaker 710 are fastened with screws 740, as shown in Figure 19(c).

[0270] On the other hand, of the four mounting sleeves 732, the second mounting sleeves 732b, which are located at the lower left corner and the upper right corner when viewed from above, are mounting sleeves in which 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 are fastened together by screws 740, as shown in Figure 19(d).

[0271] A first rectangular boss 737a having a rectangular shape is erected on the outside 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 erected on the outside 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 erected near the first mounting sleeve 732a, which are located at the upper left corner and lower right corner when viewed from above.

[0272] This through-hole identification boss 738 is a boss that is erected to identify that the two first mounting sleeves 732a out of the four mounting sleeves 732 are mounting sleeves to be fastened to the dedicated screw hole 716a (first through-hole) of the speaker 710, and is a boss that is not formed near the second mounting sleeve 732b.

[0273] According to this example, of the four mounting sleeves 732, a through-hole identification boss 738 is provided near the first two mounting sleeves 732a. 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 730 in the correct orientation, thereby preventing work errors and improving work efficiency.

[0274] Furthermore, arc-shaped mounting direction identification bosses 739 are erected 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 lower left corner when viewed from above, and between the second rectangular boss 737b, which is located in the upper right corner when viewed from above, and the first rectangular boss 737a, which is located in the lower right corner when viewed from above.

[0275] This mounting direction identification boss 739 is a boss that is erected to make it possible to identify the mounting direction of the speaker 710 and the rear cover 720, and is a boss that is not formed between the first rectangular boss 737a located in the upper left corner when viewed from above and the second rectangular boss 737b located in the upper right corner when viewed from above, nor between the second rectangular boss 737b located in the lower left corner when viewed from above and the first rectangular boss 737a located in the lower right corner when viewed from above.

[0276] According to this example, mounting direction identification bosses 739 are provided that can identify the mounting direction of speaker 710 and rear cover 720. Therefore, when mounting speaker 710 to speaker base 730, the position of lead terminals 716 of speaker 710 is aligned with mounting direction identification boss 739, making it possible to mount speaker 710 in the correct orientation on speaker base 730. When mounting rear cover 720 to speaker base 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 in the correct orientation on speaker base 730. This prevents work errors when mounting speaker 710 and rear cover 720 and improves work efficiency.

[0277] <Speaker mounting structure (variation 1) / mounting method> Next, a method for attaching the speaker unit 700 will be described with reference to FIG.

[0278] When attaching the speaker unit 700 to the speaker base 730, first, as shown in Figures 19(b) and (c), the speaker 710 is attached to the speaker base 730, and then, as shown in Figures 19(c) and (d), the rear cover 720 is attached to the speaker base 730.

[0279] 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.

[0280] Next, as shown in Figure 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 the speaker 710 is attached to the speaker base 730 by fastening with screws 740.

[0281] Note that speaker 710 has a shape that is nearly point-symmetric, and can be attached to speaker base 730 even when rotated 180 degrees, which makes it possible to easily attach speaker 710.

[0282] Furthermore, because the lead terminal 716 and the 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 has been completed, the speaker 710 can be rotated 180 degrees and attached to the speaker base 730, and the lead terminal 716 and the lead wire 717 can be connected later, and even when the speaker 710 has been attached to the speaker base 730, the wiring of the lead wire 717 can be changed and the lead terminal 716 and the lead wire 717 can be connected later.

[0283] Next, when attaching rear cover 720 to speaker base 730, screw holes 724 of rear cover 720 are identified using screw hole identification recesses 724a and screw hole identification grooves 722a as landmarks, and then the screw holes 724 are aligned with second mounting sleeve 732b using second rectangular boss 737b of speaker base 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, and the rear surface of speaker 710 is covered with rear cover 720, thereby positioning rear cover 720 relative to speaker base 730.

[0284] 19(d), the rear cover 720 is attached to the speaker base 730 by aligning the screw holes 724 of the rear cover 720 with the shared screw holes 716b of the speaker 710 and the holes of the mounting sleeve 732b of the speaker base 730 and fastening them with screws 740. In this way, the speaker unit 700 is integrated and fixed to the back surface of the front door 102.

[0285] According to this example, when fixing speaker 710 and rear cover 720 to speaker base 730 with screws 740, they can be fixed at once with one screw 740 via shared screw hole 716b of speaker 710 and screw hole 724 of rear cover 720, which simplifies the work of attaching the members compared to conventional methods. Also, since rear cover 720 can be fixed to speaker base 730 after speaker 710 has been fixed and positioned on the base using dedicated screw hole 716a, there is no need to position the two members simultaneously, which improves work efficiency.

[0286] 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, which makes it easier to attach rear cover 720.

[0287] 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 easy to position the rear cover 720 (second member) relative to the speaker 710 (first member), ensuring reliable attachment of the second member.

[0288] Furthermore, a screw accommodating space 723a1 (accommodating space) having a predetermined space is formed in protruding piece 723a (a certain portion) of rear cover 720 (second member), and therefore even when rear cover 720 is positioned relative to the rear surface of speaker 710, the head of screw 740 (fixing means) attached to dedicated screw hole 716a (first through hole) of speaker 710 (first member) is accommodated in screw accommodating space 723a1 (space portion), so that screw 740 (fixing means) does not interfere with rear cover 720 (second member), and rear cover 720 (second member) can be securely attached to the rear surface of speaker 710 (first member).

[0289] In particular, when screws are used as the fixing means, if the screws are not tightened enough 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 screw accommodating space 723a1 (accommodating space) that can accommodate at least a part of screw 740 (fixing means) is formed in rear cover 720 (second member), it is possible to avoid the risk of interference between rear cover 720 (second member) and the screw head.

[0290] Furthermore, 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. This reduces the stroke of the screw 740 (fixing means) that fastens both the shared 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), improving work efficiency. Furthermore, part of the head of the screw 740 (fixing means) can be accommodated in a screw hole identification recess 724a formed around the third through-hole, making it difficult for the screw 740 (fixing means) to come loose, thereby enabling the speaker 710 (first member) and the rear cover 720 (second member) to be stably fixed to the speaker pedestal 730 (base). Furthermore, the screw hole identification recess 724a (around the third through-hole) also functions as a positioning point when attaching the screw 740 (fixing means).

[0291] Furthermore, when attaching the speaker 710 and the rear cover 720, a common screw 740 (a screw of the same length and thickness) can be used, which eliminates the need to use multiple types of screws, improving convenience and eliminating screw attachment errors, allowing the components to be attached reliably.

[0292] In addition, since a common screw 740 is used to attach the speaker 710 and the rear cover 720, the length of the screw 740 must be at least as long as the thickness of the screw hole 724 in the rear cover 720 plus the thickness of the common screw hole 716b in the speaker 710.

[0293] 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.

[0294] 19(d), when the rear cover 720 is attached to the speaker base 730, the bottom of the rear cover 720 is supported not only by the four mounting sleeves 732 but also by a cylindrical cover support portion 735 located on the right side when viewed from above. In other words, when the speaker 710 (first member) and the rear cover 720 (second member) are fixed to the speaker base 730 (base), a portion of the rear cover 720 (second member) comes into contact with the mounting sleeves 732 and 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).

[0295] Furthermore, as explained 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).

[0296] 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 it is possible to pull out the lead wires 717 (wiring) of the speaker 710 to the outside of the speaker 710 (first member) and the rear cover 720 (second member) through these spaces.

[0297] <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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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 (for example, the shared screw hole 716b shown in FIG. 17(d)) ​​that are different from the first through-hole, and the second member includes a plurality of third through-holes (for example, the screw hole 724 shown in FIG. 17(b)), and the The gaming machine is characterized in that one 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 (for example, a protruding piece with a screw hole 723b shown in Figure 17(b)) is formed near the third through hole in the second member, and a concave portion (for example, a screw hole identification groove 722a shown in Figure 17(b)) is formed in the convex portion near the third through hole.

[0298] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-hole and the multiple second through-holes are arranged around the outer periphery of the first member in the order of the second through-hole, the first through-hole, and the second through-hole. This allows the two first and second members to be stably fixed together using the second through-holes arranged on both sides of the first through-hole. Furthermore, 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 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.

[0299] The plurality of second through holes may be provided at the outer end of the second member.

[0300] With this configuration, the second member can be stably fixed to the base.

[0301] The base may also 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)).

[0302] With this configuration, even when the second member is removed from the base, the first member can be stably fixed to the base.

[0303] Furthermore, 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 Figure 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 Figure 17(d)) ​​may be approximately the same.

[0304] With this configuration, the first member can be stably fixed to the base, thereby improving safety and workability.

[0305] 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, or when the first through hole is located approximately in the center between the second through holes located on both sides of it, etc.).

[0306] Furthermore, 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, the second through hole may be located at a position on the first member that is diagonal to the first member (the vertex at the end of the diagonal), or at a position on the first member that is not diagonal to the first member, or may be located near the vertex, or may be located along a side, or may be located at a position other than the outer edge.

[0307] Furthermore, 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.

[0308] With this configuration, even if a portion of the first member is covered by the second member, the wiring of the first member can be drawn out to the outside, thereby increasing the degree of freedom in design.

[0309] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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 member and the second 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 first through hole and the plurality of second through holes are arranged alternately on the outer periphery of the first member, a protrusion (for example, 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 recess (for example, a screw hole identification groove 722a shown in Figure 17(b)) is formed in the protrusion near the third through hole.

[0310] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-hole and the multiple second through-holes are arranged around the outer periphery of the first member in the order of the second through-hole, the first through-hole, and the second through-hole. This allows the two first and second members to be stably fixed together using the second through-holes arranged on both sides of the first through-hole. Furthermore, 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 used when fixing to the base, or whether it is used when fixing both the first member and the second member to the base, thereby improving the efficiency of the member installation work.

[0311] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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)), and the first 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, the second through hole, and the first through hole is configured so 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, the protruding piece 723a of the rear cover 720 shown in Figure 19(d)).

[0312] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-hole and the multiple second through-holes are arranged around the outer periphery of the first member in the order of the second through-hole, the first through-hole, and the second through-hole. This allows the two first and second members to be stably fixed together using 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, the first through hole of the first member is configured to be covered by a certain portion of the second member, so that it is possible to visually confirm that there is no need to use the first through hole when fixing the second member, and it is possible to easily position the second member relative to the first member, ensuring reliable installation of the second member.

[0313] Furthermore, the first member and the second member are configured to be fixable (or to be fixed) to the base by a fixing means (for example, a screw 740 shown in Figures 16 and 19), and an accommodation space (for example, 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.

[0314] With this configuration, a portion of the fastening means attached to the first through hole of the first member is accommodated in the accommodation space, so the fastening 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 fastening means, if the screw is not tightened enough when the first member is fixed to the base, the screw head may protrude more than necessary from the first through hole. However, because the second member has an accommodation space that can accommodate at least a portion of the fastening means, the risk of interference between the second member and the screw head can be avoided.

[0315] 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 be fixed) to the base by the fixing means.

[0316] With this configuration, for example, if a screw is used as the fixing means, if the screw is not tightened enough when the first member is fixed to the base, the head of the screw may protrude more than necessary from the first through hole.However, since the second member has an accommodation space that can accommodate 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] The second member may be made of a material that allows the first member to be visible from the outside when the first member is housed inside.

[0318] 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, the positional relationship between the first member and the second member, etc., thereby improving convenience when installing the members.

[0319] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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 19(d) ) in a state where the first member and the second member are fixed to the base, the first through-hole is a through-hole used when the first member of the first and second members 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, 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 configured to be 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) ).

[0320] According to the gaming machine of this embodiment, when the first and second members are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member has been fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, since the first through-hole and the multiple second through-holes are alternately arranged around the outer periphery of the first member, the two first and second members can be stably fixed together using the second through-holes arranged on both sides of the first through-hole. Furthermore, since the first and second members are configured so that the first through-hole of the first member is covered by a portion of the second member when the first and second members are fixed to the base, it is possible to visually confirm that the first through-hole is not required for the second member to be fixed. Furthermore, the second member can be easily positioned relative to the first member, ensuring reliable installation of the second member.

[0321] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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)). The second member includes a plurality of third through-holes (for example, 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 the portion where the third through hole is formed is configured as a thin portion that is thinner than the surrounding area of ​​the portion (for example, a screw hole identification recess 724a shown in Figures 17(a) and (b)).

[0322] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-hole and the multiple second through-holes are arranged around the outer periphery of the first member in the order of the second through-hole, the first through-hole, and the second through-hole. This allows the two first and second members to be stably fixed together using the second through-holes arranged on both sides of the first through-hole. Furthermore, because the area where the third through hole is formed is a thin-walled portion that is thinner than the surrounding area, the stroke amount of a fastening 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. In addition, because a portion of the head of the fastening means can be accommodated in the thin-walled portion around the third through hole, the fastening means is less likely to come off, allowing the first member and the second member to be stably fastened to the base. Furthermore, the thin-walled portion formed around the third through hole also functions as a positioning device when attaching the fastening means.

[0323] 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.

[0324] 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 thin-walled portion around the third through hole.

[0325] Furthermore, 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)).

[0326] 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 it is also possible to easily position the second member relative to the first member, ensuring reliable installation of the second member.

[0327] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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)). (e.g., screw hole 724 shown in Figure 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 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 (e.g., screw hole identification recess 724a shown in Figures 17(a) and (b)).

[0328] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at the same time via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the first member can be fixed to the base and positioned using the first through-hole, the second member can be fixed to the base. This eliminates the need to simultaneously position the two members, improving work efficiency. Furthermore, since the first through-hole and the multiple second through-holes are alternately arranged around the outer periphery of the first member, the two first and second members can be stably fixed together using the second through-holes arranged on both sides of the first through-hole. Furthermore, because the area where the third through hole is formed is a thin-walled portion that is thinner than the surrounding area, the stroke amount of a fastening 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. In addition, because a portion of the head of the fastening means can be accommodated in the thin-walled portion around the third through hole, the fastening means is less likely to come off, allowing the first member and the second member to be stably fastened to the base. Furthermore, the thin-walled portion formed around the third through hole also functions as a positioning device when attaching the fastening means.

[0329] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 720 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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 (for example, the shared screw hole 716b shown in FIG. 17(d)) ​​that are different from the first through-hole, and the second member includes a plurality of third through-holes (for example, the screw hole 724 shown in FIG. 17(b)), and the first through-hole is The gaming machine is characterized in that 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 is configured so that when the first member and the second member are fixed to the base, a part of the second member abuts on 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.

[0330] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-hole and the multiple second through-holes are arranged around the outer periphery of the first member in the order of the second through-hole, the first through-hole, and the second through-hole. This allows the two first and second members to be stably fixed together using 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 on 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, the wiring of the first member can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0331] Furthermore, 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 drawn out to the outside of the first member and the second member through the space.

[0332] With this configuration, even if a portion of the first member is covered by the second member, the wiring of the first member can be drawn out to the outside, thereby increasing the degree of freedom in design.

[0333] Furthermore, the second member may have a space portion having a predetermined space (for example, a box-shaped space 722S shown in Figures 17(a) and (b)), and the space portion is configured to be able to accommodate at least a portion of the wiring, and the space portion may be configured to have a first space portion having a vertically elongated rectangular parallelepiped shape (for example, a first space portion 722S1 shown in Figures 17(a) and (b)) and a second space portion having a horizontally elongated rectangular parallelepiped shape (for example, 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.

[0334] With this configuration, when fixing the second member to the base, a wider area can be secured other than the area where the base and the second member come into contact (around the through hole), thereby preventing the wiring from getting pinched between the base and the second member.

[0335] The first space and the second space may be disposed on the second member outside the third through hole (outside the radial direction of the second member).

[0336] With this configuration, the second space portion in the shape of a horizontally elongated rectangular parallelepiped ensures a wide 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.

[0337] Furthermore, 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 FIGS. 17(c) and (d)) that can be fixed to a base (for example, the speaker base 730 shown in FIG. 16 and FIG. 19), and a second member (for example, the back cover 620 shown in FIG. 16 and FIGS. 17(a) and (b)) that can cover at least a part of the first member, wherein 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)), The gaming machine is characterized in that 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 on 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)).

[0338] According to the gaming machine of this embodiment, when the first member and the second member are fixed to the base, they can be fixed at the same time via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the first member can be fixed to the base and positioned using the first through-hole, the second member can be fixed to the base. This eliminates the need to simultaneously position the two members, improving work efficiency. Furthermore, since the first through-hole and the multiple second through-holes are alternately arranged around the outer periphery of the first member, the two first and second members can be stably fixed together using 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 on 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, the wiring of the first member can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0339] <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.

[0340] As shown in Figure 20(a), the speaker unit 800 of variant example 2 is composed of a speaker 810 (first member) for low-frequency output having a large diaphragm, and a rear cover 820 (second member) that covers the rear side of this speaker 810, and is attached to a speaker pedestal 830 (base) formed below the rear surface of the front door 102 of the slot machine.

[0341] In the slot machine (gaming machine) of this example, two speaker base portions 830 are arranged horizontally at a predetermined interval on the back surface of the front door 102, and each speaker base portion 830 is configured to allow a speaker unit 800 to be attached.

[0342] FIG. 20(b) is an external perspective view showing two speaker units 800 attached to the rear surface of the front door 102. FIG.

[0343] 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 portion 830 to the outside, are wired along the back 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.

[0344] 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, or the speaker units 800 may be arranged vertically or diagonally on the back surface of the front door 102.

[0345] 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 terminals 816 of the speaker 810 face upward and the lead wires 817 of the speaker 810 are drawn out from above (the direction shown in FIG. 20(b) ; hereinafter, this may be referred to as the “upward direction”), or in a direction in which the box-shaped space 822S of the rear cover 820 and the lead terminals 816 of the speaker 810 face rightward and the lead wires 817 of the speaker 810 are drawn out from the right side (hereinafter, this may be referred to as the “rightward direction”). The speaker 810 can be attached in any one of the following directions: a direction in which the box-shaped space 822S of the rear cover 820 and the lead terminal 816 of the speaker 810 face downward, and the lead wire 817 of the speaker 810 is drawn out from the bottom (hereinafter, this direction may be referred to as the "downward direction"); and a direction in which the box-shaped space 822S of the rear cover 820 and the lead terminal 816 of the speaker 810 face left, and the lead wire 817 of the speaker 810 is drawn out from the left side (hereinafter, this direction may be referred to as the "leftward direction").

[0346] According to this example, the speaker unit 800 can be disposed in an upward, rightward, downward, or leftward direction relative to the speaker base 830, thereby increasing the degree of freedom in attaching the speaker unit 800.

[0347] 20(b), the two speaker units 800 are both attached facing upward, so that the lead wires 817 of the two speakers 810 can be pulled out from above and then gathered together 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, medal selector, etc. above the speaker unit 800, or enclosed gaming machines that do not have a tray, etc. above the speaker unit 800).

[0348] On the other hand, when applied to a gaming machine where it is difficult to secure space above the speaker unit 800 (for example, a slot machine in which a hopper, medal selector, etc. is 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 installed in a direction other than upward, such as downward, rightward, or leftward, the lead wire 817 of the speaker 810 can be routed to avoid other devices arranged above the speaker unit 800, which not only improves the efficiency of wiring work but also makes effective use of the limited space behind the front door 102.

[0349] 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, if the speaker unit 800 arranged on the left side of the front door 102 when viewed from the back is installed facing right, while the speaker unit 800 arranged on the right side of the front door 102 when viewed from the back is installed facing left, 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, thereby improving the efficiency and maintainability of wiring work.

[0350] Furthermore, the length of the lead wire 817 of the speaker 810 is not particularly limited, as long as it is long enough to allow 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, if the length is set to the minimum required when the speaker unit 800 is installed in an upward direction, and the lead wire 817 is configured so that if the speaker unit 800 is installed in a direction other than upward, the length of the lead wire 817 is insufficient to connect to the sound output control means, 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.

[0351] <Speaker mounting structure (variation 2) / speaker base> 20(a), speaker pedestal 830 (base) is configured to include an annular diaphragm support part 831 that supports outer edge 813a (see FIG. 22; part 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 fits inside diaphragm support part 831. The detailed configuration of speaker pedestal 830 (base) will be described later using FIG. 23.

[0352] In addition, one of multiple cylindrical bosses 835 for fixing the title panel 162 (see Figure 1) attached to the lower front of the front door 102 is arranged in the space formed by the diaphragm support portion 831 and the back of the front door 102.

[0353] 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 back surface of the front door 102, so that the limited space behind the front door 102 can be effectively utilized, thereby enabling space saving on the back surface of the front door 102.

[0354] <Speaker mounting structure (variation 2) / speaker, rear cover> Next, the speaker 810 and rear cover 820 that constitute the speaker unit 800 according to the second modification will be described in detail with reference to FIGS.

[0355] 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, viewed from the underside of speaker 810.

[0356] <Speaker mounting structure (variation 2) / Speaker> Speaker 810 (first component) is a cone-type dynamic speaker, and as shown in Figure 21(c), is generally composed of an electromagnetic circuit 811 (electrical component) consisting of a voice coil and a magnet, and vibrating diaphragm 813 (described later) in response to an electric signal, a frame 812 that supports this electromagnetic circuit 811, diaphragm 813 that vibrates to generate sound, a flat flange 814 to which diaphragm 813 is fixed so that it can vibrate, a lead terminal 816 arranged on the upper side of flange 814 when viewed from above, and a lead wire 817 (wiring) detachably connected to lead terminal 816.

[0357] 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 its side to allow air to escape around diaphragm 813. That is, a plurality of openings 815 are formed in the circumferential direction on the side of frame 812, and struts 812a (see FIG. 20) are formed in the front-to-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.

[0358] 21(d), oval-shaped dedicated screw holes 816a (first through holes) for screwing speaker 810 to speaker base 830 are formed in the upper left and lower right corners of the outer edge of flange 814. Also, oval-shaped 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 and upper right corners of the outer edge of flange 814.

[0359] The size and shape of the dedicated screw hole 816a (first through hole) and the common screw hole 816b (second through hole) are not particularly limited, but in this example, as shown in Figure 22, the dedicated screw hole 816a (first through hole) and the common 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.

[0360] 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, so that the dedicated screw holes 816a (first through holes) and the common screw holes 816b (second through holes) are arranged alternately at a predetermined interval in the circumferential direction along the outer edge of the flange 818.

[0361] In other words, as shown in Figure 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 line (the vertices at the ends of the diagonal line) of the virtual rectangle VQ, and the plurality of common screw holes 816b (second through holes) are arranged on a (second) diagonal line (the vertices at the ends of the diagonal line) different from the first diagonal line) of the virtual rectangle VQ.

[0362] Furthermore, when focusing on the distance between the dedicated screw hole 816a (first through hole) and the common 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 common screw holes 816b (second through holes) (for example, the common screw hole 816b located in the upper right corner) is almost the same as the shortest distance L4 from the dedicated screw hole 816a (first through hole) located in the upper left corner to a second through hole of the two common screw holes 816b (second through holes) other than the one through hole (for example, the common screw hole 816b located in the lower left corner).

[0363] According to this example, when the speaker 810 (first member) is fixed to the speaker pedestal portion 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 portion 830 (base), the speaker 810 (first member) can be stably fixed, thereby improving safety and workability.

[0364] Furthermore, 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 degree of freedom in installing speaker 810.

[0365] <Speaker mounting structure (variation 2) / rear cover> Next, the rear cover 820 (second member) will be described.

[0366] The rear cover 820 (second member) is a colored, transparent resin member capable of housing the speaker 810 inside, and is made of a material that allows the speaker 810 (first member) to be visible from the outside when the speaker 810 (first member) is housed inside.

[0367] According to this example, at least a portion of speaker 810 (first member) can be seen through rear cover 820 (second member), and therefore the fixed position of speaker 810 (first member) relative to speaker base 830 (base), the positional relationship between speaker 810 (first member) and rear cover 820 (second member), etc. can be confirmed, thereby improving convenience in the work of installing the members.

[0368] The 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.

[0369] As shown in Figures 21(a) and (b), the rear cover 820 has a circular cover portion 821 formed on the rear side that covers part of the rear end of the 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.

[0370] A predetermined marking 826 (in this example, a part number and material) is provided on the upper side of cover portion 821 as viewed from above. The display mode of predetermined marking 826 is not particularly limited, but in this example, a part number marking (in this example, the character string "SPxxxx") indicating the part number of rear cover 820 is engraved on the surface of cover portion 821 to the left of a portion where lead terminals 816 of speaker 810 are visible when rear cover 820 is covering speaker 810, and a material marking (in this example, the character string "PC") indicating the material of rear cover 820 is engraved on the right of a portion where lead terminals 816 of speaker 810 are visible when rear cover 820 is covering speaker 810.

[0371] 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.

[0372] According to this example, in addition to the predetermined markings 826 being provided on the rear cover 820, when the speaker 810 is viewed through the rear cover 820, the lead terminals 816 of the speaker 810 are visible. Therefore, the correct orientation (attachment direction) of the rear cover 820 can be easily identified depending on the orientation of the predetermined markings 826 and whether the lead terminals 816 of the speaker 810 are visible in the center of the predetermined markings 826, thereby improving convenience when attaching the rear cover 820, etc.

[0373] As shown in FIG. 21(b), the rear cover 820 has two protruding pieces 823a and two protruding pieces 823b with screw holes that protrude outward from the outer edge of the side wall portion 822.

[0374] 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 the 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 the 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 the side wall portion 822.

[0375] In other words, as shown in Figure 21(b), when the vertices of the multiple protrusions 823a and the protrusions 823b with screw holes on either side of the multiple protrusions 823a are connected by an imaginary straight line VL2, an imaginary rectangle VQ2 is formed, and the multiple protrusions 823a are arranged on a (first) diagonal line (the vertices at the ends of the diagonal line) of the imaginary rectangle VQ2, and the multiple protrusions 823b with screw holes are arranged on a (second) diagonal line (different from the first diagonal line) of the imaginary rectangle VQ2 (the vertices at the ends of the diagonal line).

[0376] The protruding pieces 823b with screw holes, which are located diagonally between the lower left and upper right corners (at the vertices of the ends of the diagonal), have circular screw holes 824 (third through holes) formed therein for integrating the speaker 810 and rear cover 820 and screwing them to the speaker base portion 730.

[0377] 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 830 (base) with a screw 840 (fixing means; see FIG. 20), the speaker unit 800 is integrated and fixed to the speaker pedestal 730. The method of attaching the speaker unit 800 will be described later.

[0378] 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.

[0379] According to this example, at least one of the dedicated screw holes 816a (first through-holes), the shared screw holes 816b (second through-holes), and the screw holes 824 (third through-holes) (in this example, the screw holes 824 (third through-holes)) is configured to be identifiable, so that it is easy to determine whether each through-hole is used to secure only the speaker 810 (first member) to the speaker base 830 (base) or whether each through-hole is used to secure both the speaker 810 (first member) and the rear cover 820 (second member) to the speaker base 830 (base), thereby improving the efficiency of the work of attaching components. Furthermore, the correct orientation (attachment direction) of the rear cover 820 can be easily identified using the screw hole identification grooves 822a, improving convenience when attaching the rear cover 820, etc.

[0380] In this example, screw hole identification groove 822a is formed near screw hole 824 (third through hole) as a configuration for making screw hole 824 (third through hole) identifiable, but the present invention is not limited to this. For example, a part for making screw hole 824 (third through hole) identifiable may be formed in a member other than rear cover 820 (second member) (for example, speaker base 830 (base) or speaker 810 (first 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.

[0381] Furthermore, although a configuration has been exemplified in which the screw hole 824 (third through hole) of the rear cover 820 can be identified, 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 member) can be identified.

[0382] 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 on 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 at least one of the through holes may be marked, printed, engraved, or the like that allows at least one of the through holes to be identified, or the flag of the speaker 810 (first member) may be attached. The holder 814 may be formed 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.

[0383] Furthermore, by making the shape of the protruding piece 823b with the screw hole of the rear cover 820 different from the shape of the protruding piece 823a, it may be possible to identify that the through hole formed in the protruding piece 823b with the screw hole is 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), or conversely, by making the shape of the protruding piece 823a of the rear cover 820 different from the shape of the protruding piece 823b with the screw hole, it may be possible to identify that the through hole in the speaker 810 corresponding to the protruding piece 823a is a through hole used when fixing only the speaker 810 (first member) to the speaker base part 830 (base).

[0384] 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.

[0385] Also, as shown in Figure 21(b), protruding pieces 823a arranged diagonally at the upper left corner and lower right corner of the rear cover 820 have through holes 825 (fourth through holes) formed therein that have an inner diameter larger than the inner diameter of the screw holes 824 (third through holes).

[0386] As shown in FIG. 22, this through hole 825 (fourth through hole) has an inner diameter larger than that of the oval-shaped common screw hole 816b (second through hole) of the speaker 810, and as shown in FIG. 23(d), has an inner diameter larger than the outer diameter of the head of the screw 840.

[0387] 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 rear cover 820 can be accurately positioned relative to the speaker 810.

[0388] 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 oval shared screw holes 816b (second through holes) of speaker 810, so that any assembly error of rear cover 820 relative to speaker 810 (shifting of rear cover 820) can be absorbed and the attachment work can be simplified.

[0389] In this example, an example in which a through hole is formed in protruding piece 823a of rear cover 820 has been shown, but the present invention is not limited to this, and for example, instead of a through hole, a portion such as a recess or notch that will not interfere with screw 840 may be formed in protruding piece 823a, or protruding piece 823a itself may be removed from rear cover 820. In other words, when speaker 810 is fixed to the rear surface of front door 102 with screw 840, it is sufficient to configure so that screw 840 attached to dedicated screw hole 816a of speaker 810 does not interfere with rear cover 820.

[0390] As shown in Figure 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 accommodating the lead terminals 816 of the speaker 810 and leading the lead wires 817 to the outside of the speaker unit 800.

[0391] With this configuration, as shown in FIG. 22, when the speaker 810 (first member) is housed inside the rear cover 820 (second member), a space SP is formed between the speaker 810 (first member) and the rear cover 820 (second member), and the lead wire 817 (wiring) of the speaker 810 can be pulled out to the outside of the speaker 810 (first member) and the rear cover 820 (second member) through this space SP.

[0392] According to this example, even if a portion of the speaker 810 (first member) is covered by the rear cover 820 (second member), the lead wire 817 (wiring) of the speaker 810 (first member) can be pulled out to the outside, thereby increasing the degree of freedom in design.

[0393] As shown in FIG. 22, four protruding ribs 827 are formed on the inside bottom surface of rear cover 820, which can come into contact with four flange corners 814a of flange 814 of speaker 810, 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.

[0394] According to this example, by abutting four ribs 827 of rear cover 820 against any of four flange corners 814a of flange 814 of speaker 810 and abutting lower edge 820a of rear cover 820 against the outer edge of one side of flange 814 of speaker 810, it is possible to easily and reliably position speaker 810 relative to rear cover 820 and integrate speaker 810 and rear cover 820. Therefore, by using installation method 2 described below, speaker 810 and rear cover 820 can be attached to speaker base 830 in an integrated state, simplifying the installation work of speaker unit 800.

[0395] Furthermore, 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 degree of freedom in terms of attachment of the rear cover 820.

[0396] 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 predetermined markings 826 is facing up and predetermined markings 826 are easily visible. However, even if rear cover 820 is attached facing right, downward, or left, the predetermined markings 826 will be upside down, but it will still be possible to attach it to speaker base 830.

[0397] <Speaker mounting structure (variation 2) / speaker base> Next, the speaker pedestal 830 (base) will be described in detail with reference to FIG.

[0398] 23(a) to (d) are diagrams showing an example of a method for attaching the speaker unit 800 in chronological order, and FIG. 23(a) is a diagram showing the speaker base part 830 with the sound hole plate 834 removed.

[0399] As explained using Figure 20(a), speaker base 830 (base) is composed of a circular diaphragm support part 831 that supports outer edge part 813a of diaphragm 813 of speaker 810 (see Figure 22; the part that supports the outer edge of the cone of diaphragm 813), 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 fits inside diaphragm support part 831.

[0400] The height of the frame support part 831 (height from the back of the front door 102) is designed to be higher than the maximum vibration amplitude of the diaphragm 813 of the speaker 810 so as not to inhibit the vibration of the diaphragm 813, and a sound hole plate 834 is fitted inside it, as shown in Figure 23(b).

[0401] As shown in Figure 23(c), when speaker 810 is attached to speaker base 830, outer edge 813a of diaphragm 813 of speaker 810 abuts against frame support 831, and an enclosed space is formed by speaker base 830 and diaphragm 813 of speaker 810.

[0402] 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 through the sound hole plate 834 toward the front of the front door 102, thereby improving the acoustic effect.

[0403] Of the four mounting sleeves 832, the first mounting sleeves 832a, which are located at the upper left and lower right corners 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 Figure 23(c).

[0404] On the other hand, of the four mounting sleeves 832, the second mounting sleeves 832b, which are located at the lower left corner and the upper right corner when viewed from above, are mounting sleeves in which 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 are fastened together by screws 840, as shown in Figure 23(d).

[0405] 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 Figure 22) of the flange 814 of the speaker 810 can be placed.

[0406] According to this example, when attaching speaker 810 to speaker base 830, flange corner 814a of flange 814 of speaker 810 is placed on rib 838 of mounting sleeve 832, thereby enabling speaker 810 to be positioned easily and reliably, and preventing speaker 810 from shifting or rattling when attached.

[0407] <Speaker mounting structure (variation 2) / mounting method 1> Next, a first method for mounting the speaker unit 800 will be described with reference to FIG.

[0408] When attaching the speaker unit 800 to the speaker base 830, first, as shown in Figures 23(b) and (c), the speaker 810 is attached to the speaker base 830, and then, as shown in Figures 23(c) and (d), the rear cover 820 is attached to the speaker base 830.

[0409] More specifically, when attaching speaker 810 to speaker base 830, with lead terminals 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 relative to speaker base 830.

[0410] Next, as shown in Figure 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 part 830 and fastened with a screw 840, thereby attaching only the speaker 810 to the speaker base part 830.

[0411] Furthermore, since the lead terminal 816 and the lead wire 817 of the speaker 810 are configured to be detachable, even when the wiring of the lead wire 817 up to the speaker base part 830 is completed, it is possible to rotate the speaker 810 by 90 degrees, 180 degrees, or 270 degrees, attach it to the speaker base part 830, and connect the lead terminal 816 and the lead wire 817 later, and even when the speaker 810 is attached to the speaker base part 830, it is possible to change the wiring of the lead wire 817 and connect the lead terminal 816 and the lead wire 817 later.

[0412] Next, when attaching the rear cover 820 to the speaker base 830, the position of the box-shaped space 822S of the rear cover 820 is aligned with the lead terminal 816 of the speaker 810, and with the rear cover 820 facing upward, the screw holes 824 of the rear cover 820 are aligned with the second mounting sleeve 832b, and the rear cover 820 is then placed over the speaker 810, thereby positioning the rear cover 820 relative to the speaker base 830.

[0413] 23(d), rear cover 820 is attached to speaker base 830 by aligning screw holes 824 of rear cover 820 with shared screw holes 816b of speaker 810 and the holes of second mounting sleeve 832b of speaker base 830 and fastening with screws 840. In this way, speaker unit 800 is integrated and fixed to the back surface of front door 102.

[0414] 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 all at once with one screw 840 via shared screw hole 816b of speaker 810 and screw hole 824 of rear cover 820, thereby simplifying the work of attaching the members compared to conventional methods. Also, it is possible to fix rear cover 820 to speaker base 830 after speaker 810 has been fixed and positioned on the base using dedicated screw hole 816a, so there is no need to position the two members at the same time, improving work efficiency.

[0415] Furthermore, 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 accommodated in the through hole 825 (fourth through hole) without coming into contact with 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 positioned so that the speaker 810 is securely attached to the rear cover 820. 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 housed inside through holes 825 and the horizontal movement of rear cover 820 is restricted by screws 840, so that rear cover 820 can be prevented from shifting or rattling when rear cover 820 is attached.

[0416] In particular, when screws are used as a fixing means, if the screws are not tightened enough 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, since through hole 825 (fourth through hole) is formed in rear cover 820, it is possible to avoid the risk of interference between rear cover 820 (second member) and the screw head.

[0417] 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 holes 816a (first through holes) of the speaker 810 (first member) are configured not to be covered by the rear cover 820 (second member), and the screws 840 are configured to come into contact only with 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 holes 816a (first through holes) of the speaker 810 (first member) are 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 becomes possible to fix the speaker 810 (first member) thereafter using the dedicated screw hole 816a (first through hole), thereby making the installation work more convenient.

[0418] Furthermore, when attaching the speaker 810 and the rear cover 820, a common screw 840 (a screw of the same length and thickness) can be used, which eliminates the need to use multiple types of screws, increasing convenience and eliminating screw installation errors, allowing the components to be attached reliably.

[0419] In addition, since a common screw 840 is used to attach 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 common screw hole 816b in the speaker 810.

[0420] 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 becomes 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.

[0421] Furthermore, as shown in Figure 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 fraudster were to try to remove the speaker unit 800, it would appear that the removal would take a long time, thereby preventing fraudulent acts.

[0422] 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.

[0423] 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.

[0424] 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.

[0425] <Speaker mounting structure (variation 2) / mounting method 2> Next, a second method for mounting the speaker unit 800 will be described.

[0426] 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.

[0427] More specifically, when first assembling speaker 810 and rear cover 820 and attaching them to speaker base 830, the positions of lead terminals 816 of speaker 810 and box-shaped space 822S of rear cover 820 are aligned, and then speaker 810 is covered with rear cover 820 to be integrated, and shared screw hole 816b of speaker 810 and screw hole 824 of rear cover 820 are aligned with second mounting sleeve 832b, thereby positioning speaker 810 and rear cover 820 relative to speaker base 830.

[0428] Next, the common 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 portion 830.

[0429] 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 attachment sleeve 832a.

[0430] 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. In this way, the speaker unit 800 is fixed to the rear surface of the front door 102 as a single unit.

[0431] According to this example, an appropriate mounting method can be selected from the plurality of mounting methods (mounting methods 1 and 2) depending on the skill of the worker, thereby improving work efficiency.

[0432] <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 and FIGS. 21(c) and (d)) that can be fixed to a base (for example, the speaker base 830 shown in FIG. 20 and FIG. 23), and a second member (for example, the back cover 820 shown in FIG. 20 and FIGS. 21(a) and (b)) that can cover at least a part of the first member, wherein the first member includes 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 (for example, the shared screw hole 816b shown in FIG. 21(d)) that are different from the first through holes, and the second member includes a plurality of third through holes (for example, the screw hole 824 shown in FIG. 21(b)), and the first through holes are 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, and 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 gaming machine is 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 by imaginary straight lines (for example, straight line VL shown in Figure 21(d)), an imaginary rectangle (for example, rectangle VQ shown in Figure 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 (for example, diaphragm support portion 831 shown in Figure 20 or Figure 23(a)) formed to match the shape of the first member (for example, outer edge portion 813a of diaphragm 813 of speaker 810).

[0433] According to the gaming machine of this embodiment, when the first and second members are fixed to the base, they can be fixed in one step via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned on the base using the first through-hole, there is no need to simultaneously position the two members, thereby improving work efficiency. Furthermore, the first through-holes are arranged between the plurality of second through-holes, and when imaginary lines connect the plurality of first through-holes with the second through-holes on both sides of the plurality of first through-holes, an imaginary rectangle is formed. The plurality of first through-holes are arranged at the vertices of the imaginary rectangle. Therefore, the two first and second members can be stably fixed together by the second through-holes arranged on both sides of the first through-hole. Furthermore, 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 for efficient attachment work and the frame portion to stably fix the first member to the base.

[0434] Furthermore, 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 21(c) or (d)) that can be fixed to a base (for example, the speaker base 830 shown in FIG. 20 or 23), and a second member (for example, a back cover 820 shown in FIG. 20 or 21(a) or (b)) that can cover at least a part of the first member, wherein the first member includes 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 (for example, the shared screw hole 816b shown in FIG. 21(d)) that are different from the first through holes, and the second member includes a plurality of third through holes (for example, the screw hole 824 shown in FIG. 21(b)), and the first through holes are used to fix the first member of the first member and the second member. The gaming machine is characterized in that the first through hole is a through hole used when fixing to the base, and 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, and is configured so that when the plurality of first through holes and the second through holes on either side of the plurality of first through holes are connected by imaginary straight lines (for example, the straight line VL shown in Figure 21(d)), an imaginary rectangle (for example, the rectangle VQ shown in Figure 21(d)) is formed, and the plurality of first through holes are configured to be positioned at the vertices of the ends of the diagonal lines 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.

[0435] According to the gaming machine of this embodiment, when the first and second members are fixed to the base, they can be fixed at the same time via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned on the base using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-holes are arranged between the plurality of second through-holes, and when imaginary lines are connected between the plurality of first through-holes and the second through-holes adjacent to the plurality of first through-holes, an imaginary rectangle is formed. The plurality of first through-holes are arranged at the vertices of the diagonal ends of the imaginary rectangle. Therefore, the two first and second members can be stably fixed together 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 if the first member has wiring, etc., the wiring, etc. can be pulled out to the outside through the space, thereby increasing the degree of freedom in design.

[0436] Furthermore, 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 and FIGS. 21(c) and (d)) that can be fixed to a base (for example, the speaker base 830 shown in FIG. 20 and FIG. 23), and a second member (for example, the back cover 820 shown in FIG. 20 and FIGS. 21(a) and (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, 21(d)) and a plurality of second through holes different from the first through hole (for example, a dedicated screw hole 816a shown in FIG. 21(d)) (for example, a common 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 20 and 23(a)) formed to match the shape of the first member (for example, the outer edge 813a of the diaphragm 813 of the speaker 810). In this gaming machine, the first through holes are through holes used to fix both the first member and the second member to the base, and 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 by imaginary straight lines (for example, the straight lines VL shown in FIG. 21(d)), an imaginary rectangle (for example, the 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 diagonal lines of the imaginary rectangle. The base is configured to have a frame portion (for example, the diaphragm support portion 831 shown in FIG. 20 or 23(a)) formed to match the shape of the first member (for example, the outer edge 813a of the diaphragm 813 of the speaker 810). When the first member and the second member are fixed to the base, a part of the second member abuts against the support portion provided on the base, thereby forming a space between the second member and the base.

[0437] According to the gaming machine of this embodiment, when the first and second members are fixed to the base, they can be fixed at the same time via the second through-hole of the first member and the third through-hole of the second member. This simplifies the installation process compared to conventional systems and allows the two first and second members to be stably fixed together. Furthermore, since the second member can be fixed to the base after the first member is fixed and positioned on the base using the first through-hole, there is no need to simultaneously position the two members, improving work efficiency. Furthermore, the first through-holes are arranged between the plurality of second through-holes, and when imaginary lines are connected between the plurality of first through-holes and the second through-holes adjacent to the plurality of first through-holes, an imaginary rectangle is formed. The plurality of first through-holes are arranged at the vertices of the diagonal ends of the imaginary rectangle. Therefore, the two first and second members can be stably fixed together by the second through-holes arranged on both sides of the first through-hole. Furthermore, because the base includes a frame portion formed to match the shape of the first member, the first member can be attached while being reliably positioned relative to the base, allowing for efficient attachment work and enabling the frame portion to stably secure the first member to the base. Furthermore, when the first member and the second member are secured to the base, a portion of the second member abuts against a support portion provided on the base, forming a space between the second member and the base. Therefore, even if the first member has wiring or the like, the wiring or the like can be pulled out to the outside through the space, thereby increasing the degree of freedom in design.

[0438] Furthermore, the first member may be configured to be fixable to the base by a first fixing means (e.g., a screw 840 shown in Figure 20(a) or Figure 23(d)) and a second fixing means (e.g., a screw 840 shown in Figure 20(a) or Figure 23(d)), and 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.

[0439] 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, allowing for efficient installation work. Furthermore, even if the first member and the second member are first fixed to the base using the second and third through holes, it is possible to subsequently fix the first member using the first through hole, thereby making installation work more convenient.

[0440] The second member may also have a plurality of fourth through holes (for example, through holes 825 shown in Figures 21(b) and 23(d)), the third through holes being through holes that are arranged in positions corresponding to the second through holes of the first member in the first state, the fourth through holes being through holes that are arranged in positions corresponding to the first through holes of the first member in the first state, the size of the fourth through holes being larger than the size of the third through holes, and the second fixing means being visible through the fourth through holes in the first state.

[0441]

[0010] With this configuration, when the first member or the second member is properly attached to the base and the first member is covered with the second member, the fastening means attached to the first through hole of the first member can be received inside the fourth through hole, and the fastening means does not interfere with the second member. Therefore, it is easy to visually confirm that the second member is properly attached to the first member based on the positional relationship between the fourth through hole and the fastening means. Furthermore, when the second member is properly positioned relative to the first member, the fastening means is received inside the fourth through hole, and movement of the second member is restricted by the fastening means. Therefore, misalignment or rattle of the second member can be prevented when the second member is attached. Furthermore, because the fastening means is visible through the third through hole and the fourth through hole, even if a fraudulent person attempts to remove the first member or the second member, it is made to believe that removal will take a long time, thereby preventing fraudulent acts, etc.

[0442] 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.

[0443] 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.

[0444] <Speaker mounting structure (variant 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.

[0445] As shown in Figure 24(a), the speaker unit 850 of variant example 3 is composed of a speaker 860 (first member) for low-frequency output having a large diaphragm, and a rear cover 870 (second member) that covers the rear side of this speaker 860, and is attached to speaker base parts 880 (left speaker base part 880L, right speaker base part 880R) arranged below the rear surface of the front door 102 (base) of the slot machine.

[0446] A left speaker base 880L and a right speaker base 880R are arranged horizontally at a predetermined distance below the rear surface of the front door 102, and a speaker unit 850 can be attached to each of the left speaker base 880L and the right speaker base 880R.

[0447] Specifically, the speaker unit 850 is attached to the left speaker base portion 880L (first area) located on the left side of the front door 102 when viewed from behind, with the box-shaped space 872S of the rear cover 870 and the lead terminal 866 of the speaker 860 facing right when viewed from behind, and with the lead wire 867 of the speaker 860 pulled out from the right side (first orientation, hereinafter sometimes referred to as the "right-facing direction").

[0448] 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 direction; hereinafter, sometimes referred to as the "left-facing direction").

[0449] 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 (right-facing) or a second orientation (left-facing) 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 (right-facing), and can be attached to the second area (right speaker base portion 880R) in the second orientation (left-facing).

[0450] 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.

[0451] Furthermore, 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 880L) but cannot be attached to the second area (right speaker base 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 880R) but cannot be attached to the first area (left speaker base 880L).

[0452] 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 in accordance with the structure and specifications of the gaming machine, while also preventing installation errors.

[0453] 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 in the front of the box-shaped space 872S, are wired along the back 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.

[0454] 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 first member (speaker 860) can be drawn out toward the center of the back of the base (front door 102), which makes it easy to route the wiring and improves the efficiency of the wiring work, and also allows the wiring to be stored in an organized manner, improving maintainability.

[0455] The manner in which the lead wire 867 of the speaker 860 is drawn 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, drawn out from the space formed between the rear cover 870 and the front door 102 to the outside, wired along the back of the front door 102, and electrically connected to a sound output control means arranged above the front door 102.

[0456] Furthermore, for example, when applied to a gaming machine where it is difficult to secure space above the speaker unit 850 (for example, a slot machine in which a hopper, medal selector, etc. is arranged above the speaker unit 850, or a pachinko machine in which a tray, etc. is arranged above the speaker unit 850), the lead wire 867 of the speaker 860 can be routed around other devices arranged above the speaker unit 850, which not only improves the efficiency of wiring work but also makes effective use of the limited space behind the front door 102.

[0457] 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, or the speaker units 850 may be arranged vertically or diagonally on the back surface of the front door 102.

[0458] Furthermore, the length of the lead wire 867 of the speaker 860 is not particularly limited, as long as it is long enough to allow 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, the length may be the minimum required when the speaker unit 850 is installed facing left or right, and if 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 facing downward (in an orientation 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 mistakes in installing the speaker unit 850 on the gaming machine can be prevented in advance.

[0459] 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 box-shaped space 872S of rear cover 870 and lead terminals 866 of speaker 860 face downward in rear view, and lead wires 867 of speaker 860 are drawn from the lower side), an upward direction (a direction in which box-shaped space 872S of rear cover 870 and lead terminals 866 of speaker 860 face upward in rear view, and lead wires 867 of speaker 860 are 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 downward direction or upward direction described above, or another direction.

[0460] 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 drawn out. The positions of mounting sleeves 882 of left speaker base part 880L and right speaker base part 880R (described later) 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.

[0461] <Speaker mounting structure (variation 3) / speaker base> As shown in Figure 24(a), the left speaker base 880L and the right speaker base 880R are configured to include a circular diaphragm support part 881 that supports the outer edge (the part that supports the outer edge of the cone of the diaphragm 863) of the diaphragm 863 of the speaker 860 (see Figure 25(c) etc.), a cylindrical mounting sleeve 882 for screwing the speaker 860 and rear cover 870 to the front door 102, and a circular sound hole plate 884 that fits inside the diaphragm support part 881.

[0462] <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 back 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 (metal frame). For convenience of explanation, part of the metal plate 885 is shown in a see-through manner in Figure 24(a) and is omitted in Figure 24(b).

[0463] 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).

[0464] 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).

[0465] <Speaker mounting structure (variation 3) / speaker, rear cover> Next, a speaker 860 and a rear cover 870 that constitute a speaker unit 850 according to the third modification will be described in detail with reference to FIGS.

[0466] 25(a) is a side view of the rear cover 870, and FIG. 25(b) is a top view of the rear cover 870. Also, FIG. 25(c) is a side view of the speaker 860, and FIG. 25(d) is a top view of the speaker 860.

[0467] Also, Figure 26 is a rear view seen from the back of the front door 102 showing the state after the speaker 860 and rear cover 870 have been positioned relative to the front door 102, and Figure 27 is a rear view seen from the back of the front door 102 showing the state after the speaker 860 and rear cover 870 have been attached to the front door 102 with screws.

[0468] Also, Figure 28(a) is a side view of the speaker unit 850 attached to the left speaker base portion 880L, viewed from the left side when viewed from the rear, and Figure 28(b) is a side view of the speaker unit 850 attached to the left speaker base portion 880L, viewed from the right side when viewed from the rear.

[0469] <Speaker mounting structure (variation 3) / Speaker> Next, the speaker 860 (first member) will be described.

[0470] Speaker 860 (first component) is a cone-type dynamic speaker, and as shown in Figure 25(c), is generally 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.

[0471] 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 in the circumferential direction on its side to allow air to escape around diaphragm 863. That is, a plurality of openings 855 are formed in the circumferential direction on the side of frame 862, and struts 862a (see FIG. 24) are formed in 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.

[0472] Predetermined markings 876 (in this example, a part number and material) are applied to electromagnetic circuit 861. The display form of predetermined markings 876 is not particularly limited, but in this example, a part number marking indicating the part number of speaker 860 (in this example, a character string "SPxxxx") and a material marking indicating the material of speaker 860 (in this example, a character string "AL") are engraved on the surface of electromagnetic circuit 861.

[0473] According to this example, the speaker 860 is provided with a predetermined marking 876, and therefore the orientation of the speaker 860 (the first orientation or the second orientation described above) can be easily identified by the orientation of this predetermined marking 876, thereby improving convenience when installing the speaker 860, etc.

[0474] <Speaker mounting structure (variation 3) / Speaker / First and fourth through holes> As shown in FIG. 25(d), a first through-hole 864a1 (first hole) having an oval shape is formed in the lower left corner of the outer edge of the flange 864 of the speaker 860.

[0475] As shown in FIG. 27, 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), and is 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).

[0476] In other words, the first through hole 864a1 (first hole) is a hole that may or may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102).

[0477] 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), which may simplify the installation work of the first member (speaker 860) and the second member (rear cover 870), thereby improving work efficiency.

[0478] An identifier (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) may be provided to 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 or an unused hole, and the member to which the identifier is provided may be any of the first member, second member, third member, and base, or may be another member. The same applies to the through-holes described below.

[0479] 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 a second member to a base and improving work efficiency.

[0480] An oval-shaped fourth through-hole 864a4 (fourth hole) is formed in the upper left corner of the outer edge of the flange 864 of the speaker 860.

[0481] As shown in FIG. 27, 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 the first orientation (rightward), 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).

[0482] In other words, the fourth through hole 864a4 (fourth hole) is a hole that may or may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102).

[0483] 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), which may simplify the installation work of the first member (speaker 860) and the second member (rear cover 870), thereby improving work efficiency.

[0484] 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 symmetrical with respect to the imaginary line VL3 (see Figure 25(d)) that passes through the center of the first member (speaker 860) (positions that are approximately the same shortest distance from the imaginary line VL3).

[0485] <Speaker mounting structure (variation 3) / Speaker / 7th and 9th through holes> An oval-shaped seventh through-hole 864a7 (seventh hole) is formed in the lower right corner of the outer edge of the flange 864 of the speaker 860.

[0486] 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).

[0487] 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).

[0488] 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).

[0489] An elliptical ninth through-hole 864a9 (ninth hole) is formed in the upper right corner of the outer edge of the flange 864 of the speaker 860.

[0490] 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).

[0491] 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).

[0492] 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).

[0493] 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 symmetrical with respect to the imaginary line VL3 (see Figure 25(d)) that passes through the center of the first member (speaker 860) (positions that are approximately the same shortest distance from the imaginary line VL3).

[0494] <Speaker mounting structure (variation 3) / Speaker / 1st, 4th, 7th, and 9th through holes> As shown in Figure 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 line (the vertices at the ends of the diagonal line) of the virtual rectangle VQ, and the fourth through hole 864a4 and the seventh through hole 864a7 are arranged on the second diagonal line (different from the first diagonal line) of the virtual rectangle VQ4 (the vertices at the ends of the diagonal line).

[0495] The size and shape 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 elliptical holes with larger outer diameters than the circular second through hole 872a2 and the fifth through hole 872a5 of the rear cover 870.

[0496] 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 elliptical holes having larger outer diameters than the circular second through hole 872a2 and the fifth through hole 872a5 of the rear cover 870, so that any assembly error (misalignment of the rear cover 870) of the rear cover 870 relative to the speaker 860 can be absorbed, simplifying the installation work.

[0497] <Speaker mounting structure (variation 3) / rear cover> Next, the rear cover 870 (second member) will be described.

[0498] The rear cover 870 (second member) is a member made of a colored transparent resin that can house the speaker 860 inside, and is made of a material that allows the speaker 860 to be seen from the outside when the speaker 860 is housed inside.

[0499] 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 can be performed while checking the relative positions of speaker 860 and rear cover 870, thereby improving the convenience of the installation work.

[0500] The 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.

[0501] 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 dust and dirt from entering or adhering to speaker 860. Furthermore, rear cover 870 may be formed with guide portions (hooks or the like) for guiding lead wire 867 (wiring) of speaker 860, a ground wire connecting speaker 860 to metal plate 885 (frame ground), and the like to predetermined positions, or the guide portions may be configured to be attachable to rear cover 870 later.

[0502] As shown in Figures 25(a) and (b), the rear cover 870 has a circular cover portion 871 formed on the rear side that covers part of the rear end of the 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.

[0503] <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.

[0504] 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).

[0505] In other words, the second through hole 872a2 (second hole) is a hole that may or may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102).

[0506] 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), which may simplify the installation work of the first member (speaker 860) and the second member (rear cover 870), thereby improving work efficiency.

[0507] A circular fifth through-hole 872a5 (fifth hole) is formed in the upper left corner of the outer edge of the side wall portion 872 of the rear cover 870.

[0508] As shown in FIG. 27, 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), 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).

[0509] In other words, the fifth through hole 872a5 (fifth hole) is a hole that may or may not be used when attaching the first member (speaker 860) and the second member (rear cover 870) to the base (front door 102).

[0510] 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), which may simplify the installation work of the first member (speaker 860) and the second member (rear cover 870), thereby improving work efficiency.

[0511] 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 symmetrical with respect to the imaginary line VL5 (see Figure 25(b)) that passes through the center of the second member (rear cover 870) (positions that are approximately the same shortest distance from the imaginary line VL5).

[0512] <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.

[0513] Above the left protruding piece 873 and the right protruding piece 874 of the rear cover 870, third circular through-holes 873a3 (third holes) are formed, respectively.

[0514] 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).

[0515] 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).

[0516] 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 front door 102), which may simplify the attachment work of the second member (rear cover 870) and improve work efficiency.

[0517] Either one of the two third through holes 873a3 (third holes) may be used for attachment to the third member (metal plate 885).

[0518] Below the left protruding piece 873 and the right protruding piece 874 of the rear cover 870, sixth circular through-holes 873a6 (sixth holes) are formed, respectively.

[0519] As shown in FIG. 27, 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), 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).

[0520] 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).

[0521] 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 front door 102), which may simplify the attachment work of the second member (rear cover 870) and improve work efficiency.

[0522] Either one of the two sixth through holes 873a6 (sixth holes) may be used to attach the third member (metal plate 885).

[0523] 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 symmetrical with respect to the imaginary line VL5 (see Figure 25(b)) that passes through the center of the second member (rear cover 870) (positions that are approximately the same shortest distance from the imaginary line VL5).

[0524] Note that predetermined markings 877 (in this example, a part number and 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.

[0525] 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 first orientation or the second orientation described above) can be easily identified by the orientation of this predetermined marking 877, thereby improving convenience when attaching the rear cover 870, etc.

[0526] 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 use the specified markings 877 as a clue to recognize that the third through-hole 873a3 (third hole) is a hole used when attaching the second member (rear cover 870) in the first orientation (rightward) to the base (left speaker base portion 880L of the front door 102) or the third member (metal plate 885), thereby further increasing convenience when attaching the rear cover 870, etc.

[0527] <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 accommodating the lead terminal 866 of the speaker 860 and leading the lead wire 867 to the outside of the speaker unit 850.

[0528] With this configuration, when the speaker 860 is housed inside the rear cover 870, a space is formed between the speaker 860 and the rear cover 870, and as shown in Figures 26 and 27, the lead wire 867 (wiring) of the speaker 860 can be pulled out to the outside of the speaker 860 and the rear cover 870 through this space.

[0529] According to this example, even when 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.

[0530] 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 in the front 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 of the speaker 860 to the front door 102 side through the space. In this case, the box-shaped space 872S does not need to be formed in the rear cover 870.

[0531] <Speaker mounting structure (variation 3) / mounting method> Next, a method for attaching speaker unit 850 will be described.

[0532] As shown in Figures 27 and 28(a), the first member (speaker 860) and the second member (rear cover 870) facing in a first direction (to the right) are 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 passes through 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).

[0533] 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 the same time, which simplifies the work of attaching the members compared to conventional methods and also makes it possible to stably fix the two first members (speaker 860) and the second member (rear cover 870).

[0534] In addition, the second member (rear cover 870) facing in the first direction (to the right) 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 passes through a third hole (third through-hole 873a3) of the second member (rear cover 870).

[0535] The first member (speaker 860) and the second member (rear cover 870) facing in a first direction (to the right) 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 an imaginary line VL6 (see Figure 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).

[0536] According to this example, the first member (speaker 860) and the second member (rear cover 870) can be fixed to the base (left speaker base portion 880L of front door 102) vertically downward, so that the two first members (speaker 860) and the second member (rear cover 870) can be stably fixed.

[0537] 27 and 28(b), the second member (rear cover 870) facing in the first direction (rightward) is attached to the base (the mounting sleeve 882 of the left speaker base portion 880L of the front door 102) by a fastening means (screw 890) passing through a third hole (third through-hole 873a3) of the second member (rear cover 870), and the first member (speaker 860) facing in the first direction (rightward) is attached to an eighth through-hole 885a8 (eighth hole) of the third member (metal plate 885) by a fastening means (screw 890) passing through a seventh hole (seventh through-hole 864a7) of the first member (speaker 860). As a result, the first member (speaker 860) facing in the first direction (rightward) is grounded.

[0538] 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 housed 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 a part of the speaker 860 and the rear cover 870) are configured to abut (or be close to) each other.

[0539] 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 (speakers 860) and the second member (rear cover 870) to be stably fixed together.

[0540] On the other hand, as shown in FIG. 27, the first member (speaker 860) and the second member (rear cover 870) facing in the second direction (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 passes through 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).

[0541] 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 passes through a sixth hole (sixth through hole 873a6) of the second member (rear cover 870).

[0542] The first member (speaker 860) and the second member (rear cover 870) facing in the second direction (leftward) 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 the imaginary line VL6 (see Figure 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).

[0543] According to this example, the first member (speaker 860) and the second member (rear cover 870) can be fixed to the base (right speaker base portion 880R of front door 102) vertically downward, so that the two first members (speaker 860) and the second member (rear cover 870) can be stably fixed.

[0544] 27, the second member (rear cover 870) facing the second direction (left) is attached to the base (the mounting sleeve 882 of the right speaker base 880R of the front door 102) by a fastening means (screw 890) passing through a sixth hole (sixth through-hole 873a6) of the second member (rear cover 870), and the first member (speaker 860) facing the second direction (left) is attached to a tenth through-hole 885a10 (tenth hole) of the third member (metal plate 885) by a fastening means (screw 890) passing through a ninth hole (ninth through-hole 864a9) of the first member (speaker 860). As a result, the first member (speaker 860) facing the second direction (left) is grounded.

[0545] 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 housed 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 a part of the speaker 860 and the rear cover 870) are configured to abut (or be close to) each other.

[0546] 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 (speakers 860) and the second member (rear cover 870) to be stably fixed together.

[0547] 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) in 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 in the speaker 860).

[0548] 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.

[0549] <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 rear cover 870 are attached to the front door 102 with screws, as seen from the rear of the front door 102.

[0550] In this example, a metal plate 915 (third member) smaller than the metal plate 885 described using Figures 25 to 28 is erected on the back surface of the front door 102 between the left speaker base portion 880L and the right speaker base portion 880R.

[0551] 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 passes through the third hole (third through hole 873a3) of the second member (rear cover 870), and is also attached to the third member (metal plate 915) by a fixing means (screw 890) that passes through the sixth hole (sixth through hole 873a6) of the second member (rear cover 870).

[0552] In addition, the rear cover 870 (second member) facing the second direction (leftward) is attached to the base (right speaker base portion 880R of the front door 102) by a fixing means (screw 890) that passes through a 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 a fixing means (screw 890) that passes through a third hole (third through hole 873a3) of the second member (rear cover 870).

[0553] 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 attaching the second member (rear cover 870) to the third member (metal plate 915) in the second orientation (leftward).

[0554] In addition, the sixth through hole 873a6 (sixth hole) is a hole used when attaching the second member (rear cover 870) to the third member (metal plate 915) in the first orientation (rightward), as shown in FIG. 29, and is a hole 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).

[0555] In other words, the third through hole 873a3 (third hole) and the sixth through hole 873a6 (sixth hole) are holes that are always used when attaching the second member (rear cover 870) to the base (front door 102) or the third member (metal plate 885).

[0556] According to this example, the third through-hole 873a3 (third hole) and the sixth through-hole 873a6 (sixth hole) of the rear cover 870 can be effectively utilized, which increases the variety of installation work for the speaker unit 850 and can accommodate third members (metal plates 915) of various sizes and shapes, thereby increasing convenience.

[0557] 25 to 28 or metal plate 915 described using Fig. 29, and may be a member formed integrally with front door 102, or a member separate from front door 102. Furthermore, although the left and right speaker base portions 880L and 880R have a shape that is line-symmetrical with respect to an imaginary line that passes vertically (up and down) between them, the shape does not have to be line-symmetrical.

[0558] Also, an example has been shown in which metal plate 885 (or metal pl...
