Abstract

To provide a gaming machine that ensures design flexibility while suppressing a decrease in work efficiency. [Solution] The back panel is provided with a specific through-hole, a specific component is positioned in front of the specific through-hole, a specific circuit board is connected to a specific unit via wiring passed through the specific through-hole, and the specific through-hole is positioned such that, when the housing is viewed from the front, there is an area that overlaps with the specific component and is not visible, and an area that does not overlap with the specific component and is visible. By allowing partial overlap between the specific through-hole and the specific component, a greater degree of design freedom for the back panel can be ensured compared to when the specific through-hole is provided without allowing overlap. In addition, when the housing is viewed from the front, the visibility of the specific through-hole from the front is ensured by the existence of an area where the specific through-hole and the specific component do not overlap. This prevents a decrease in the work efficiency when passing wiring through the specific through-hole.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in gaming machines, it is required to ensure the freedom of design and suppress a decrease in workability.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine capable of ensuring the freedom of design and suppressing a decrease in workability.

Means for Solving the Problems

[0007] To achieve the aforementioned objective, the gaming machine according to the present invention is A gaming machine capable of communicating with a specific unit (dedicated unit 200) that can perform control related to the lending of gaming value, The system comprises a housing (housing 11) and a specific circuit board (a terminal board for connecting game balls, etc., to the dispensing device 35) located inside the housing, The enclosure comprises a top plate (top plate 2), a back plate (back plate 3), a bottom plate (bottom plate 4), and side plates (left side plate 5, right side plate 6). The back plate is provided with a specific through hole (specific through hole 38), A specific member (for example, a reel unit 31) is positioned in front of the aforementioned specific through-hole. The aforementioned specific substrate is connected to the aforementioned specific unit via wiring (harness 39) passed through the aforementioned specific through-hole. The aforementioned specific through-hole is provided in a position where, when the housing is viewed from the front, there is a range that overlaps with the specific member and is not visible, and a range that does not overlap with the specific member and is visible.

[0008] The specified through-hole is positioned such that, when the housing is viewed from the front, there is a range that overlaps with the specified member and is not visible, and a range that does not overlap with the specified member and is visible. Allowing partial overlap between the specified through-hole and the specified member provides greater design flexibility for the back panel than if the specified through-hole were provided without allowing overlap. Furthermore, the existence of a range where the specified through-hole and the specified member do not overlap when the housing is viewed from the front ensures visibility of the specified through-hole from the front. This helps to prevent a decrease in the work efficiency when routing the wiring through the specified through-hole. [Effects of the Invention]

[0009] According to the present invention, it is possible to ensure design flexibility while suppressing a decrease in work efficiency. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0011] (First Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the following, a slot machine, which is one type of gaming machine, will be described. However, the gaming machine according to the present invention is not limited to a slot machine, and may be a gaming machine such as a pachinko gaming machine or a medal-less gaming machine. Also, in the following description, basically, "front and back" means that when a player is on the front side of the slot machine, the player side is "front" and the slot machine side is "back", "up and down" means that the upper surface side of the slot machine is "up" and the lower surface side is "down", and "left and right" means that the left hand side of the player playing the slot machine is "left" and the right hand side is "right". Note that the present invention allows for free combination of each component, arbitrary deformation of each component, or omission of each component within the scope of the invention.

[0012] FIG. 1 is a perspective view showing a slot machine 100. Also, FIG. 2 is a perspective view showing the inside of the housing 1 of the slot machine 100. This slot machine 100 includes a housing 1. The housing 1 is formed in a box shape with an open front side (having a front opening). The housing 1 includes a top plate 2, a back plate 3, a bottom plate 4, and left and right side plates 5, 6. The left side plate 5 is designated as the left side plate 5, and the right side plate 6 is designated as the right side plate 6. In the present embodiment, the top plate 2, the back plate 3, the bottom plate 4, the left side plate 5, and the right side plate 6 are made of wood. Note that some of the plates may be made of resin.

[0013] In this embodiment, the inner surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 of the housing 1 are referred to as "inner surfaces." The bottom surface of the top panel 2, the front surface of the back panel 3, the top surface of the bottom panel 4, the right surface of the left panel 5, and the left surface of the right panel 6 are "inner surfaces."

[0014] In this embodiment, the outer surfaces of the enclosure 1 facing outwards on the top plate 2, back plate 3, bottom plate 4, left side plate 5, and right side plate 6 are referred to as "external surfaces." The top surface of the top plate 2, the back surface of the back plate 3, the bottom surface of the bottom plate 4, the left side of the left side plate 5, and the right side of the right side plate 6 are "external surfaces."

[0015] The front side of the housing 1 is provided with a front door 20 that can be opened and closed to close the front opening of the housing 1. The front door 20 is rotatably connected to the housing 1 via a hinge 29 and is designed to open and close the opening of the housing 1. The front door 20 may be divided into multiple doors, such as an upper part (upper door) and a lower part (lower door).

[0016] The slot machine 100 may be a so-called separable cabinet type in which, when changing machines in a gaming hall, the cabinet 1, the lower part of the front door 20, and the power supply unit 10 and hopper unit 11 inside the cabinet 1 remain attached to the island equipment of the gaming hall, while the upper part of the front door 20 and the reel unit 14 can be replaced. If the front door 20 is divided into an upper door and a lower door, the upper door and the lower door can be opened and closed relative to the cabinet 1. That is, the upper door is rotatably connected via an upper hinge 29 and opens and closes the upper part of the opening of the cabinet 1. The lower door is rotatably connected via a lower hinge 29 and opens and closes the lower part of the opening of the cabinet 1.

[0017] A flat panel 21 is provided on the upper side of the front door 20. A display device (display means, liquid crystal display) is provided on the back (rear side) of the panel 21 as a performance device. Various images (performance images) are displayed on the liquid crystal display to assist or enhance the gameplay.

[0018] A transparent display window 22 (window section) is provided in the center of the front door 20. Behind the display window 22, three reels 15a to 15c (see Figure 2) are arranged in a horizontal row. Parts of the reels 15a to 15c are visible through the display window 22. Multiple types of symbols are arranged in a row along the circumference of the outer surface of each reel 15a to 15c, and when the reels 15a to 15c stop, three consecutive symbols (upper, middle, and lower) per reel are displayed through the display window 22. The display window 22 also has upper, middle, and lower display positions for viewing the symbols on the reels 15a to 15c, and the number of active lines is determined by the combination of the display positions of the reels 15a to 15c. In the gaming machine of this embodiment, the active lines are formed by the middle section of the first reel 15a, the middle section of the second reel 15b, and the middle section of the third reel 15c.

[0019] In the gaming machine of this embodiment, the number of tokens required for one game (specified number) is set to "3", and when the specified number of tokens are inserted, the active lines are activated. When the three reels 15a to 15c stop, the combination of symbols displayed via the display window 22 indicates whether a winning combination has been achieved or not. In the slot machine 100, when the game starts, the reels 15a to 15c start to rotate, and an internal lottery is performed to determine whether one of the winning combinations is achieved or not (not achieved). Then, when the reels 15a to 15c stop, if the combination of symbols corresponding to the winning combination determined by the internal lottery is displayed on the active line, this winning combination is considered an achievement, and the process corresponding to the achieved winning combination (achievement process) is performed.

[0020] The front door 20 is equipped with lighting devices 24, 25 (lighting means), speakers (sound output means), etc., which serve as performance devices for effects (notifications), etc. Lighting device 24 is provided on the upper side of the panel 21 of the front door 20. Lighting devices 25, 25 are provided on both the left and right ends of the front door 20. Decorative members 26 having a three-dimensional shape, whether luminescent or non-luminescent, including these lighting devices 24, 25, are provided on predetermined parts of the front door 20, so that the outer shape of the front side of the gaming machine has an uneven surface. In other words, the gaming machine is decorated by the decorative members 26.

[0021] Multiple speakers (not shown) are provided on the front door 20, for example, at the top and bottom. The speakers output various sounds (music, background music, sound effects, voices, etc.) for the purpose of assisting or enhancing the game. In addition to the liquid crystal display, lighting devices 24, 25 and speakers, the machine may also be provided with movable parts that can be operated by actuators, etc., as part of the performance equipment.

[0022] An operating section 30 for operating the slot machine 100 is provided in the center of the front door 20 in the vertical direction. This operating section 30 includes a settlement button 60 operated when settling tokens (game tokens, game medium, game value), a start lever 32 operated when starting the game, stop buttons 33 (three stop buttons 33a, 33b, 33c) operated when stopping the rotation of each of the three reels 15a to 15c, a token slot 34 for inserting tokens, a reject button 70 operated when clearing a token jam that occurs below the token slot 34, and a MAX bet button 35 (bet button) operated when betting (investing) credited tokens (operated when setting the maximum bet amount). In addition to the MAX bet button 35 (first bet button), which is operated when betting 3 tokens (the specified number), there may also be a 1 bet button (second bet button) which is operated when betting 1 token.

[0023] The operation unit 30 also includes an operation panel 57 used to select game effects and other features, and a display unit 58 that displays game information. The operation panel 57 is located approximately in the center of the operation unit 30 in the width direction (left-right direction), and the display unit 58 is located to the right of the coin slot 34. The operation panel 57 includes, for example, a directional pad, a select button, and a cancel button.

[0024] Furthermore, the front door 20 is equipped with a performance button 36 (performance control unit) that is operated when advancing the performance (changing the type of performance), etc.

[0025] Furthermore, the lower part of the front door 20 is provided with a payout port 50 for dispensing (sending out) medals from inside the slot machine 100, and a tray 38 for storing the medals dispensed (paid out) from the payout port 50. Between the operation unit 30 and the tray 38, there is a lower panel 39 for decorating the appearance of the gaming machine. A light source (LED) for illumination is provided on the back side of this lower panel 39, and the lower panel 39 is illuminated from behind by the light from this light source. The lower panel 39 may be formed to be pushable and may also function as an effect control unit with the same functionality as effect buttons.

[0026] As shown in Figure 2, a reel unit 14 is provided inside the housing 1. The reel unit 14 includes three reels 15a, 15b, and 15c, each displaying multiple patterns around its circumference, as well as drive motors (stepping motors) for rotating the reels 15a to 15c. Each reel is fixed to the output shaft of its respective stepping motor.

[0027] Inside the enclosure 1, the upper surface of the bottom plate 4 is equipped with a power supply unit 10 (power supply means) that supplies power to each component, a hopper unit 11 (dispensing device) that stores and dispenses medals, and a cash box 12 that dispenses excess medals when the number of medals stored in the hopper unit 11 reaches a certain amount.

[0028] The power supply unit 10 is a roughly rectangular box shape, positioned in the lower left of the enclosure 1 (on the bottom plate 4), and fixed to the inner surface of the left side plate 5. The power supply unit 10 is equipped with a power switch (not shown), and when the power switch is turned ON, power is supplied from the power supply unit 10 to each component. Note that some components may be supplied with power even when the power supply unit 10 is OFF. A power cable (power harness) connected to a power outlet supplying commercial power (AC100V) is connected to a power connector located on the back of the power supply unit 10. Specifically, a connector at one end of the power harness is connected to the power connector, and a plug at the other end of the power harness is connected to the power outlet. The power supply board of the power supply unit 10 generates DC power (e.g., 5V, 12V, 24V, etc.) from the power supplied from outside the gaming machine via the power harness, and supplies power to each component of the gaming machine.

[0029] As shown in Figure 1, the front door 20 is equipped with a door key cylinder 66, and the front door 20 can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the front door 20 can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. In addition, an error can be cleared by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

[0030] When tokens are inserted into the token slot 34 of slot machine 100, the inserted tokens are set to the "inserted" state, up to a predetermined number (predetermined number of tokens). In addition, slot machine 100 can store up to 50 tokens as credits (storage memory), and when the MAX bet button 35 is operated while tokens are stored as credits, the stored tokens are set to the "inserted" state, up to a predetermined number.

[0031] In slot machine 100, when a medal is inserted through the medal slot 34, or when the MAX bet button 35 is operated and a specified number of medals are bet, the start lever 32 is activated, and the machine becomes ready to start playing. When the activated start lever 32 is operated, the game starts. Once the game starts, each reel begins to rotate, and when the rotation speed of each reel reaches a certain speed and becomes steady rotation, the stop button 33 is activated. When the activated stop button 33 is operated, the rotation of the reel corresponding to the operated stop button 33 stops. When all reels have stopped, the machine performs processes such as paying out medals according to the game result, or making it possible to start playing again without consuming any more medals, and one game ends.

[0032] Inside the slot machine 100 (cabinet 1), circuit boards such as a main control board (main control means) and a sub-control board (sub-control means) are provided. The sub-control board may be provided on the rear side of the front door 20.

[0033] The main control board receives input signals from input means such as the MAX bet button 35, start lever 32, and stop button 33, performs various calculations to execute the game, and controls output means such as the reel unit 14 and hopper unit 11 based on the calculation results. The sub-control board receives signals (information) sent from the main control board, performs various calculations to execute the effects, and controls various display devices such as the liquid crystal display and speakers based on the calculation results.

[0034] The main control board and the sub-control board are electrically connected, allowing the main control board to transmit various information (signals), such as information indicating the game status, to the sub-control board. However, the sub-control board cannot transmit information to the main control board. Furthermore, the functions of each board, including the main control board and sub-control board, are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, as well as software consisting of predetermined programs pre-stored in ROM, etc.

[0035] The main control board is equipped with a setting change key cylinder (not shown) and a setting change button (not shown), etc. Note that the setting change key cylinder and setting change button may also be provided, for example, on the power supply unit 10.

[0036] Figure 3 is a perspective view showing the inside of the casing 1 of the slot machine 100. An external terminal board 67 is provided inside the casing 1. In this embodiment, the external terminal board 67 is attached to the inner surface of the right side panel 6. The external terminal board 67 is provided to connect the gaming machine to external electronic devices (such as data display devices and hall computers), and various external information signals representing the status of the gaming machine are output from the external terminal board 67 to the external electronic devices. One end of an outer end plate harness (outer end plate cable) is connected to the connector of the external terminal board 67, and the other end of the outer end plate harness is connected to the external electronic devices.

[0037] Figure 4 is a view of the enclosure 1 from the front. A metal sheet 40 (shielding sheet) is attached to the inner surface (almost the entire inner surface) of the back plate 3. The metal sheet 40 is provided to suppress external noise from affecting various components (such as circuit boards) located inside the enclosure 1 (causing components to malfunction, etc.). In other words, the sheet 40 is provided to improve noise immunity. The thickness of the sheet 40 is less than 1 mm, and in this embodiment it is approximately 0.1 mm to 0.3 mm.

[0038] The back panel 3 is provided with multiple openings (back panel openings). These multiple openings include a wiring opening 70 (first back panel opening) for passing wiring (harnesses) through, a heat dissipation opening 80 (second back panel opening) for releasing heat from inside the housing 1 to the outside, and a supply opening 90 (third back panel opening) for supplying game tokens from the back side (outside side) of the housing 1 to the inside of the housing 1 (hopper unit 11). Although not shown in the illustration, a lid member that can be opened and closed is attached to the supply opening 90, and by opening the lid member, it is possible to access the inside of the housing 1 from the back side of the housing 1.

[0039] At least one wiring opening 70 is provided. In this embodiment, the wiring opening 70 includes at least a wiring opening 71 for passing a power harness connected to the power supply unit 10, and a wiring opening 72 for passing an outer end plate harness connected to the external terminal board 67. The harness (power harness and outer end plate harness) is constructed by covering a conductor (copper wire) with an insulator (insulating material: for example, polyvinyl chloride).

[0040] At least one heat dissipation opening 80 is provided, and in this embodiment, three heat dissipation openings 80 are provided. It can be said that the heat dissipation openings 80 are not openings for passing harnesses (for inserting or removing objects).

[0041] In this embodiment, first, the sheet 40 is attached to the back plate 3, which does not have any openings. Then, holes are made in both the back plate 3 and the sheet 40 using a drill or the like, thereby forming each opening and the corresponding openings in the sheet.

[0042] The wiring opening 70 is approximately circular in shape (round hole, elongated hole, etc.). However, the wiring opening 70 is not limited to approximately circular in shape; it may also be approximately square in shape (square, rectangle, etc.). Furthermore, the shape of the heat dissipation opening 80 is an elongated hole (or rectangle) that is long in the left-right direction. Note that the shape of the heat dissipation opening 80 is not limited to an elongated hole; it may also be a round hole (or a roughly circular shape) or a roughly square shape. Furthermore, the shape of the supply opening 90 is roughly rectangular.

[0043] (Specific processing) The wiring opening 70 has been subjected to the following specific processing. On the other hand, the heat dissipation opening 80 has not been subjected to the specific processing. In other words, the wiring opening 70 is an opening (hole) that has been subjected to the specific processing, but the heat dissipation opening 80 is not an opening (hole) that has been subjected to the specific processing.

[0044] One specific processing method is counterboring. Figure 5 is a perspective view of the wiring opening 72 for passing the outer end plate harness, viewed from the front and below. Figure 6 is a cross-sectional view along line AA shown in Figure 4. Counterboring here refers to the process of forming a stepped portion at the opening (edge). The counterbored wiring opening 72 has a small opening 72a and a large opening 72b, as shown in Figure 6. The small opening 72a is formed on the outer side (outside) of the back plate 3 (housing 1). The depth (width in the front-to-back direction) of the small opening 72a is approximately 13 mm. The large opening 72b is formed on the inner side (inside) of the back plate 3 (housing 1). The depth (width in the front-to-back direction) of the large opening 72b is approximately 2 mm.

[0045] The diameter (inner diameter) of the small opening 72a is approximately 30 mm. Here, regarding the wiring opening 72, if we define the opening (edge, opening end) on the outer surface side of the back plate 3 as the "first back plate outer surface opening F", then the diameter of the first back plate outer surface opening F is approximately 30 mm.

[0046] Furthermore, the diameter (inner diameter) of the large opening 72b is approximately 40 mm. Here, regarding the wiring opening 72, if we define the opening (edge, opening end) on the inner surface side of the back plate 3 as the "first back plate inner surface opening G", then the diameter of the first back plate inner surface opening G is approximately 40 mm.

[0047] In this embodiment, the opening G on the inner side of the first back plate is larger (in diameter) than the opening F on the outer side of the first back plate.

[0048] The stepped portion X in the wiring opening 72 has a depth of approximately 2 mm and a width of approximately 5 mm. The stepped portion X is formed around the entire circumference of the hole. Of the small opening 72a and the large opening 72b, the small opening 72a is formed to penetrate in the front-to-back direction, and therefore, in this embodiment, the small opening 72a may be referred to as a "through hole".

[0049] Although I will omit the explanation as it would be redundant, the wiring opening 71 for passing the power harness is also countersunk in the same way as the wiring opening 72, and includes a small opening, a large opening, a stepped section, an opening on the outer side of the first back panel, and an opening on the inner side of the first back panel.

[0050] Figures 7(a) and 7(b) show cases where a different type of processing is applied to the wiring opening 72 than the counterbore processing. In this embodiment, the specific processing is counterbore processing, but the specific processing may also be C-chamfering as shown in Figure 7(a) or R-chamfering as shown in Figure 7(b). Even when C-chamfering or R-chamfering is applied in this way, the opening G on the inner side of the first back plate will be larger (in diameter) than the opening F on the outer side of the first back plate. The specific processing can be said to be processing that makes the opening on the inner side of the first back plate larger than the opening on the outer side of the first back plate.

[0051] In this embodiment, the wiring openings 70 (wiring openings 71 and 72) for passing the harness are subjected to specific processing, and the opening on the inner side of the back plate 3 (housing 1) is larger than the opening on the outer side of the back plate 3.

[0052] The sheet 40 is provided with a sheet opening (sheet opening) corresponding to the wiring opening 70. As shown in Figure 6, the sheet opening corresponding to the wiring opening 72 is called the sheet opening 42 (first sheet opening). The sheet opening 42 is formed to match (conform to) the first back panel inner surface opening G (not the first back panel outer surface opening F). Matching (conform to) means that the size of the openings (diameters) is the same or approximately the same. Although the explanation will be omitted to avoid repetition, the sheet opening (first sheet opening) corresponding to the wiring opening 71 for passing the power harness is similarly formed to match (conform to) the first back panel inner surface opening of the wiring opening 71. In this embodiment, the sheet opening corresponding to the wiring opening 70 is formed to be larger than the through hole of the wiring opening 70 (for example, the small opening 72a shown in Figure 6).

[0053] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 with the inner surface opening of the first back panel (by shifting the position of the edge of the sheet 40 outward), contact between the harness and the sheet 40 can be suppressed. Suppressing contact between the harness and the sheet 40 has the following effects: (1) When the harness comes into contact with the sheet 40, the edge of the sheet 40 may peel off (tear) a part of the sheet 40, and the peeled-off sheet 40 may come into contact with the circuit board inside the housing 1, causing a short circuit (component failure). Such problems can be suppressed. (2) When the edge (surface) of the harness and the sheet 40 come into contact (rub against each other), the harness may be damaged (the harness insulation may be torn), potentially leading to a break in the wire. Such problems can be suppressed. In addition, if the harness insulation peels off and the conductor is exposed, the possibility of the conductor coming into contact with the sheet 40 (electrical conductivity) can be reduced. According to this embodiment, it is possible to provide a gaming machine that combines the noise reduction effect of the sheet 40 with the effect of suppressing component damage (failure) through specific processing.

[0054] Figure 8 is a view of the supply opening 90 from an oblique angle above. In this embodiment, as shown in Figure 8, the supply opening 90 is also counterbore (a stepped portion Y is provided). The supply opening 90 comprises a small opening 91 (opening L on the outer surface of the first back plate), a large opening 92 (opening M on the inner surface of the first back plate), and a stepped portion Y. The stepped portion Y has a depth of approximately 8 mm and a width (around the circumference) of approximately 20 mm. The sheet 40 is provided with a sheet opening 43 (third sheet opening) corresponding to the supply opening 90. The sheet opening 43 is formed to align with the opening M on the inner surface of the first back plate (not the opening L on the outer surface of the first back plate). By aligning the sheet opening 43 with the opening M on the inner surface of the first back plate (by shifting the position of the edge of the sheet 40 outward), it is possible to suppress the sheet 40 from being peeled off when game tokens are supplied to the hopper unit 11 due to contact between the game tokens and the sheet 40.

[0055] Figure 9 is a cross-sectional view along the BB line shown in Figure 4. In this embodiment, no special processing is applied to the heat dissipation opening 80 through which the harness does not pass. Therefore, the heat dissipation opening 80 is formed such that the opening P on the inner side of the first back plate aligns (matches) with the opening Q on the outer side of the first back plate around its entire circumference. In other words, the size (diameter) of the opening P on the inner side of the first back plate and the opening Q on the outer side of the first back plate are the same. It can also be said that the heat dissipation opening 80 does not have any stepped portions and is composed only of through holes. Unlike the wiring opening 70, the opening on the inner side of the back plate 3 (housing 1) of the heat dissipation opening 80 does not extend outward beyond the opening on the outer side of the back plate 3.

[0056] The sheet 40 is provided with a sheet opening 44 (second sheet opening) corresponding to the heat dissipation opening 80. The sheet opening 44 is formed to align (match) with the opening P on the inner surface of the first back plate. Since the heat dissipation opening 80 does not allow the harness to pass through, there is no possibility of contact between the harness and the sheet 40, and therefore no special processing is required for the heat dissipation opening 80. By omitting the special processing related to the heat dissipation opening 80, the production efficiency of the component (back plate) can be improved. In addition, by not applying special processing to the heat dissipation opening 80, the area of ​​the sheet 40 can be increased, and the noise immunity performance can be improved.

[0057] In this embodiment, a sheet 40 is provided on the inner surface of the back plate 3, and wiring openings 70 (wiring openings 71 and 72) and heat dissipation openings 80 are provided on the back plate 3 (see Figure 4). The housing 1 comprises a top plate 2, a back plate 3, a bottom plate 4, a left side plate 5, and a right side plate 6. The sheet 40 may be provided on the inner surface of the plates other than the back plate 3, and wiring openings 70 (wiring openings 71 and 72) and / or heat dissipation openings 80 may be provided on those plates. In other words, the sheet 40 may be provided on the inner surface of at least one plate, and wiring openings 70 (wiring openings 71 and 72) and / or heat dissipation openings 80 may be provided on that plate. Furthermore, the wiring openings 70 (with specific processing) and the heat dissipation openings 80 (without specific processing) may be provided on separate plates. Also, the wiring opening 71 for the power harness and the wiring opening 72 for the outer end plate harness may be provided on separate plates.

[0058] In this embodiment, if the sheet 40 is provided not only on the inner surface of the back panel 3 but also on the inner surface of the side panels (left panel 5 and / or right panel 6), the noise immunity can be further improved. Furthermore, if the sheet 40 is provided on the inner surface of the top panel 2 and / or bottom panel 4, the noise immunity can be further improved.

[0059] Incidentally, the top panel 2 has an opening (top panel opening 2a: screw hole shown in Figure 3) through which fasteners (e.g., screws) for fixing the housing 1 to the island equipment of the amusement arcade are passed (inserted). The fasteners are screwed into the top panel opening 2a from the inner side of the top panel 2 and tightened (screwed from bottom to top). Also, inside the housing 1, there is a circuit board unit (e.g., a relay circuit board unit) having a predetermined circuit board (e.g., a relay circuit board). The circuit board unit comprises a circuit board and a case that houses the circuit board, and components (electronic components, connectors, etc.) are arranged on the circuit board surface of the circuit board. The case also has a connector opening for exposing the connector. The circuit board is positioned so that its circuit board surface faces the top panel 2.

[0060] If the sheet 40 is attached to the inner surface of the top panel 2, the sheet 40 may be scraped when the fixing device is inserted into the top panel opening 2a, potentially causing metal powder (dust) to fall downwards. If the metal powder falls and enters the circuit board unit (through the connector opening), it may cause a short circuit in the circuit board (causing component failure). Therefore, the enclosure 1 may be configured so that the sheet 40 is not provided on the inner surface of the top panel 2. In other words, component failure prevention may be prioritized over noise countermeasures. In this case, component failure due to metal powder falling when the enclosure 1 is fixed to the island equipment can be prevented.

[0061] In this embodiment, a harness (wiring) is passed through the wiring opening 70 (wiring opening 71 and wiring opening 72) which has been specially processed. However, the member passed through the wiring opening 70 is not limited to wiring; other members (conductive members: game tokens, screws, nails, etc.) may also be used. Furthermore, the wiring opening 70 may be a token supply hole, a screw hole, or a nail hole. Because the wiring opening 70 has been specially processed, it is possible to prevent the other member from coming into contact with the sheet 40.

[0062] The gaming machine of this embodiment is A gaming machine equipped with a casing (e.g., casing 1), The predetermined plates that constitute the outer shape of the housing (e.g., back plate 3, bottom plate 4) are provided with a metal sheet (e.g., sheet 40) on the inner side. The aforementioned predetermined plate is provided with through holes (e.g., small openings 72a, coin supply holes, screw holes, nail holes) for passing conductive members (e.g., wiring, game tokens, screws, nails), The sheet is provided with a sheet opening (e.g., sheet opening 42) for passing the conductive member through, The sheet opening is larger than the through hole.

[0063] Furthermore, the gaming machine of this embodiment is A gaming machine equipped with a casing (e.g., casing 1), The back plate (e.g., back plate 3) that constitutes the outer shape of the housing is provided with a metal sheet (e.g., sheet 40) on its inner surface. The back plate is provided with a first back plate opening (e.g., wiring opening 72) for passing wiring (e.g., outer end plate harness), The sheet is provided with a first sheet opening (e.g., sheet opening 42) for passing the wiring through, The first back panel opening is such that the first inner back panel opening on the inner side of the back panel (e.g., the first inner back panel opening G) is larger than the first outer back panel opening on the outer side of the back panel (e.g., the first outer back panel opening F). The first sheet opening is positioned to coincide with the first back panel inner surface opening.

[0064] When wiring (conductive material) comes into contact with a metal sheet, the sheet may peel or detach, potentially causing internal components to malfunction. Furthermore, the wiring (conductive material) may be damaged, leading to breakage (such as disconnection). In this embodiment, contact between the wiring (conductive material) and the metal sheet can be suppressed, thereby preventing these problems. Additionally, by providing a metal sheet on the inner surface of a predetermined plate (back panel), noise immunity can be improved. This allows for the provision of a gaming machine that combines noise reduction and component damage prevention effects.

[0065] Furthermore, in the gaming machine of this embodiment, The side panels (e.g., left panel 5, right panel 6) that constitute the outer shape of the housing are provided with the sheet on their inner surface. The top plate (e.g., top plate 2) that constitutes the outer shape of the enclosure does not have the sheet on its inner surface. The aforementioned top plate is provided with a top plate opening (e.g., top plate opening 2a) for passing fasteners through, Inside the aforementioned housing, a circuit board unit (e.g., a relay circuit board unit) having a predetermined circuit board (e.g., a relay circuit board) is provided, The predetermined substrate is positioned so that its substrate surface faces the top plate.

[0066] By adding a sheet to the side panels, noise immunity can be further improved. Furthermore, by not adding a sheet to the top panel, metal dust generated when fixing the enclosure to the island equipment can be prevented from adhering to the circuit board inside the enclosure and causing component failure.

[0067] Furthermore, in the gaming machine of this embodiment, The back plate is provided with a second back plate opening (for example, a heat dissipation opening 80) for heat dissipation. The sheet is provided with a second sheet opening (e.g., a sheet opening 44) corresponding to the second back panel opening. The second back panel opening is configured such that the second back panel inner side opening (second back panel inner side opening P) on the inner side of the back panel coincides with the second back panel outer side opening (second back panel outer side opening Q) on the outer side of the back panel. The second seat opening is designed to coincide with the inner surface opening of the second back panel.

[0068] Regarding the heat dissipation holes, by aligning the opening on the inner side of the back plate with the opening on the outer side of the back plate, and by aligning the opening of the second sheet with the opening on the inner side of the back plate, the surface area of ​​the sheet can be increased, thereby improving noise immunity.

[0069] Figure 10 shows the lower right inner side of the back plate 3, which is the rear side of the cash box 12 (Figure 3). The back plate 3 is provided with a pair of conductive rods: a first conductive rod 111 (first sensor) and a second conductive rod 112 (second sensor). The first conductive rod 111 and the second conductive rod 112 protrude forward for a predetermined length. The first conductive rod 111 and the second conductive rod 112 are arranged in a vertical (up and down) line with a predetermined spacing between them. Metal fittings (crimp terminals, connectors) are connected to the bases of the first conductive rod 111 and the second conductive rod 112, and these fittings are connected to a harness (wiring).

[0070] The first conductive rod 111 and the second conductive rod 112 can be housed (entered) inside the cash box 12. As described above, the cash box 12 is supplied with surplus tokens from the hopper unit 11. When game tokens are supplied to the cash box 12, they gradually accumulate inside the cash box 12 and come into contact with the second conductive rod 112 below. At this point, the first conductive rod 111 and the second conductive rod 112 are not electrically connected.

[0071] Furthermore, when game tokens are supplied to the cash box 12, the accumulated game tokens come into contact with the upper first conductive rod 111. At this time, the first conductive rod 111 and the second conductive rod 112 become electrically conductive. When the first conductive rod 111 and the second conductive rod 112 become electrically conductive, a signal is input to the main control board, and the main control board detects an error (cash box full error) based on the input of this signal. The main control board sends a command to the sub-control board indicating the detection of the error, and when the sub-control board receives the command, it notifies the occurrence of the error via the display device. This allows the staff of the gaming parlor to notice the occurrence of the error and take action to resolve it.

[0072] In this embodiment, the area around the first conductive rod 111 and the second conductive rod 112 in the back plate 3 is a recess 120. The recess 120 is a vertically elongated, roughly rectangular shape and is recessed toward the rear for a predetermined length (for example, about 5 mm). No specific processing (counterboring) is performed on the recess 120. Here, the opening on the inner surface side of the back plate 3 with respect to the recess 120 is referred to as the inner surface opening T.

[0073] The sheet 40 is provided with a sheet opening 45 (fourth sheet opening) corresponding to the recess 120. The sheet opening 45 is formed to align with the inner side opening T. As a result, the sheet 40 is not provided on the inside (bottom and sides) of the recess 120, and the material constituting the backing plate 3 (e.g., wood) is exposed inside the recess 120.

[0074] (modified version) In this embodiment, a metal sheet 40 is attached to the inner surface of a wooden board (e.g., back plate 3), and specific processing is applied to the wiring openings 70 (wiring openings 71 and 72). In this modified example, at least one board constituting the housing 1 (referred to as the back plate 3) is made of metal, and the sheet 40 is not attached to the inner surface of this board. By making at least one board of the housing 1 (back plate 3) of metal, noise immunity can be improved (even without providing the sheet 40). The metal back plate 3 is provided with wiring openings for the power harness (or outer end plate harness). Since the wiring openings are openings (holes) provided in the metal board, there is a high possibility that the harness will be damaged if it comes into contact with the openings. No specific processing is applied to the wiring openings in this modified example. In this modified example, instead of specific processing, a rubber (non-conductive material) ring is attached to the wiring opening. The annular rubber ring is fitted so as to cover the entire circumference of the wiring opening, and the harness passes inside the ring. Therefore, the harness may come into contact with the rubber ring, but it will not come into contact with the metal back plate 3 (or its opening). This prevents the harness from being damaged (broken). In this modified example, the metal plate (for example, back plate 3) is provided with heat dissipation openings, but rubber rings are not attached to the heat dissipation openings that do not pass wiring through.

[0075] (Second Embodiment) Next, a second embodiment of the present invention will be described. Since the gaming machine according to this embodiment has basically the same configuration as the gaming machine according to the first embodiment, the explanation of the same configuration as the gaming machine according to the first embodiment will be omitted or simplified.

[0076] The gaming machine of this embodiment is a gaming machine 101 that uses game value as electronic information instead of game tokens as a game medium, and the game is played by consuming or assigning game value. The gaming machine 101 (Figure 11) is a so-called smart pachinko slot (registered trademark). Unlike conventional slot machines in which players insert physical tokens when playing and receive physical tokens when winning combinations are achieved, the gaming machine 101 is a gaming machine (medalless gaming machine) that uses game value as electronic information instead of physical tokens, and the game value is consumed or assigned through gameplay. Furthermore, the game value in a medalless gaming machine corresponds to the game value in conventional slot machines, which is the tokens. Since the game value in a medalless gaming machine can be understood as virtual tokens (electronic tokens), the game value in this embodiment may also be referred to as tokens (game tokens). In addition, below, the number of game values ​​may be considered as the number of virtual tokens, and the number of game values ​​may be indicated as "~ tokens" or "~ items".

[0077] Figure 11 is a perspective view of the gaming machine 101 as seen from the front. As shown in Figure 11, the gaming machine 101 of this embodiment comprises a box-shaped housing 1 with an opening on the front side, which faces the player, and a front door 12 that opens and closes the front opening of the housing 1. The front door 12 is divided into an upper door 12a and a lower door 12b, and these upper door 12a and lower door 12b can be opened and closed relative to the housing 11. The front door 12 may also be a single, integrated structure that is not divided into an upper door 12a and a lower door 12b. The enclosure 1 is formed in a box shape with an open front (having a front opening). The enclosure 1 comprises a top plate 2, a back plate 3, a bottom plate 4, and left and right side plates 5 and 6. The left side plate 5 is referred to as the left side plate 5, and the right side plate 6 is referred to as the right side plate 6. In this embodiment, the top plate 2, back plate 3, bottom plate 4, left side plate 5, and right side plate 6 are made of wood. Some of the plates may be made of resin.

[0078] In this embodiment, the inner surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 of the housing 1 are referred to as "inner surfaces." The bottom surface of the top panel 2, the front surface of the back panel 3, the top surface of the bottom panel 4, the right surface of the left panel 5, and the left surface of the right panel 6 are "inner surfaces."

[0079] In this embodiment, the outer surfaces of the enclosure 1 facing outwards on the top plate 2, back plate 3, bottom plate 4, left side plate 5, and right side plate 6 are referred to as "external surfaces." The top surface of the top plate 2, the back surface of the back plate 3, the bottom surface of the bottom plate 4, the left side of the left side plate 5, and the right side of the right side plate 6 are "external surfaces."

[0080] The enclosure 11 contains a reel unit comprising a rotatable first reel 15a, a second reel 15b, and a third reel 15c, as well as a main control means, a sub-control board, a game value control board, and the like.

[0081] A liquid crystal display 13 (display means) is provided approximately in the center of the upper door 12a as a performance device. The liquid crystal display 13 displays various images (performance images) to assist or enhance the game. A speaker 14 (sound output means) is provided on the lower door 12b as a performance device. The speaker 14 outputs various performance sounds (music, sound effects, voices, etc.) to assist or enhance the game. A lamp 38 (lighting device, lighting means, outer perimeter lamp) is provided on the front door 12 for notification and performance purposes. In addition, movable parts that can be operated by actuators, etc., may be provided as performance devices.

[0082] Furthermore, a display window 16 is provided on the upper door 12a. Behind the display window 16 (the first display area 13a, described later), the reel unit is positioned so that a portion of it can be seen through the display window 16. Each reel 15a to 15c has its outer surface divided into 20 sections (20 areas) at regular intervals, and one of several types of symbols is placed in each section. In other words, multiple types of symbols are arranged in a row on the outer surface of each reel 15a to 15c. When each reel 15a to 15c stops, three symbols per reel (upper, middle, and lower) are displayed through the display window 16. The display window 16 is also provided with upper, middle, and lower sections as display positions for viewing the symbols of each reel 15a to 15c, and the number of active lines is set by the combination of the display positions of each reel 15a to 15c. In this embodiment, the effective line is composed of the upper section of the first reel 15a, the middle section of the second reel 15b, and the lower section of the third reel 15c.

[0083] In this embodiment, the number of game values ​​required for one game (specified number, specified number of tokens) is set to 3, and when the specified number of game values ​​is inserted, the active lines are activated. As the game starts, each reel 15a to 15c starts to rotate and an internal lottery is performed to determine whether one of the winning combinations is won or lost (not won). Next, when the reels 15a to 15c stop, if the symbol combination corresponding to the winning combination determined by the internal lottery is displayed on the active line, this winning combination is awarded, and the processing corresponding to the awarded winning combination (award processing) is performed. In other words, whether or not a winning combination has been awarded is indicated by the symbol combination displayed through the display window 16 when the reels 15a to 15c stop. The active lines can be described as lines for determining whether a winning combination has been awarded.

[0084] The lower door 12b (operation panel) is equipped with a bet button 35 which is operated when betting (inserting) game value, a start lever 32 (game start operation means) which is operated when starting the game, a stop button 33 (stop operation means) (stop buttons 33a, 33b, 33c) which is operated when stopping the rotating reels, and an effect button 36 (effect operation means) which is operated when advancing the effects, etc. Furthermore, the bet button 35 may include a MAX bet button (first bet button) which is operated when betting 3 units (a specified number of units) of game value, and a 1 bet button (second bet button) which is operated when betting 1 unit of game value.

[0085] The performance button 36 is operated when advancing the performance (changing the manner of the performance), etc. The performance button 36 is formed to be pressable, and when pressed, for example, the manner of the performance image displayed on the liquid crystal display 13 changes. By providing the performance button 36 and enabling its operation at predetermined triggers, it is possible to increase the player's sense of participation in the game and improve the enjoyment of the game. For example, the performance button 36 becomes operational when a performance is being executed that makes the player expect to transition to a favorable state, and an image instructing the player to perform the operation is displayed on the liquid crystal display 13 (PUSH performance). When the performance button 36 is operated, the result of the game (for example, whether or not the player transitions to a favorable state) is announced. Note that the performance button 36 is not limited to the shape of a button, but may also be in the shape of a lever, etc., as long as it is configured to be able to detect the player's operation.

[0086] Furthermore, a door key cylinder 66 is provided on the lower door 12b. The lower door 12b (front door 12) can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the lower door 12b can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. Alternatively, an error can be cleared by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

[0087] Furthermore, a lower panel 39 is provided on the lower door 12b. A light source (LED) for illumination is provided on the back side of the lower panel 39, and the lower panel 39 is illuminated from behind by the light emitted from this light source.

[0088] Although not shown in the diagram, a dedicated unit (game value lending device, game token lending device) for lending game value is provided on the side (right side) of the gaming machine 101. The front of the dedicated unit is provided with a banknote slot for inserting banknotes, a card insertion / discharge slot for inserting / discharging cards (game value management medium), a lending button (lending operation means), a replay button (lending operation means), and a card return button, etc.

[0089] In the dedicated unit, an operation on the lending button (pressing the button) is accepted as a lending operation (game value transfer operation) that transfers game value to the gaming machine 101. When the lending button is pressed, the stored value, etc., that is stored as a prepaid balance in the banknotes or cards inserted into the banknote slot is consumed, and a predetermined number (for example, 50) of game value is credited to the gaming machine 101. In addition, in the dedicated unit, an operation on the replay button (pressing the button) is accepted as a lending operation (game value transfer operation) that transfers game value to the gaming machine 101. When the replay button is pressed, the game value owned by the player, which is managed by the card (game value linked to the card), is consumed, and a predetermined number (for example, 50) of game value is credited to the gaming machine 101. In this embodiment, an operation on the lending button or replay button, which serves as a lending operation means, is received as a lending operation (game value transfer operation), and based on the lending operation, a predetermined number of game values ​​are transferred (lent) from the dedicated unit to the game machine 101.

[0090] The lower door 12b is equipped with a game token count display device 211 (game value display device, game value indicator), a counting button 212, and a payout button 218. The game token count display device 211 and the counting button 212 are located on the side (right side) of the lower door 12b. Based on the lending operation in the dedicated unit 200, the gaming machine 101 sets a value equivalent to a predetermined number of game values ​​in the credit (game value memory area). The stored value in the game value memory area can also be called the number of credits (stored number, number held). The number of credits (number of game tokens usable for gameplay) is displayed on the game token count display device 211. The game token count display device 211 has a 5-digit (or 6-digit) 7-segment display, and the number of credits is displayed on this 7-segment display. In the gaming machine 101, the upper limit of the number of credits may be set, for example, within the range of values ​​that can be displayed on the game token count display device 211. In the gaming machine 101, when the bet button 35 is operated while the game value is stored in credits, the stored game value is set to the payout state up to a predetermined limit.

[0091] The game value control board (game value control means) controls the number of game values ​​stored in the game value memory area. Based on the occurrence of a predetermined role (minor role) and the awarding of a predetermined number of game values, the game value control board increases the number of credits by that predetermined number. Furthermore, when an operation to insert game values ​​(operation of the bet button 35) is performed at the start of the game, the game value control board decreases the number of credits by the amount of game values ​​inserted. The game medal display device 211 displays a value obtained by subtracting the number of bets from the number of medals held (number of credits).

[0092] Furthermore, the game value control board controls the reception of game value transferred from the dedicated unit to the gaming machine 101. When game value is transferred from the dedicated unit to the gaming machine 101, the game value control board increases the number of credits by the amount of game value being transferred. The game value control board also controls the transfer of game value from the gaming machine 101 to the dedicated unit. When game value is transferred from the gaming machine 101 to the dedicated unit, the game value control board decreases the number of credits by the amount of game value being transferred. The game value control board also displays the number of credits stored on the game medal display device 211 and changes the display content of the game medal display device 211 according to the increase or decrease in the number of credits.

[0093] The counting button 212 is operated when sending (returning, transferring) information (credits) indicating a value equivalent to a predetermined number of credits (all or part of the total number of credits) to a dedicated unit. The counting button 212 is equipped with a pressable part (operation part), and the pressable part is formed to be pressable. When a player finishes playing, etc., the credited game value can be transferred from the gaming machine 101 to the dedicated unit based on an operation (press operation) of the counting button 212 as a counting operation (return operation). Then, after the game value has been transferred to the dedicated unit, when an operation (press operation) of the card return button is performed, a card that allows the player to know the number of game values ​​they possess is ejected from the dedicated unit (card insertion / discharge slot).

[0094] Based on the lending operation on the dedicated unit, a predetermined number of game values ​​(game tokens) are assigned to the game machine 101 (credits are added). Next, when the bet button 35 is operated, the game values ​​are set to the input state up to a predetermined limit, and a value equivalent to the number of game values ​​(game tokens) set to the input state is subtracted from the credits. That is, the number of game values ​​displayed on the game token display device 211 decreases. When the predetermined number of game values ​​are set to the input state, the start lever 32 becomes operational, that is, it becomes possible to start playing. Next, when the game start operation is performed on the activated start lever 32, the rotation of each reel 15a to 15c begins. Next, when the rotation speed of the reels increases to a predetermined speed and enters a steady rotation state, the stop buttons 33a to 33c become operational. Next, when the activated stop buttons 33a to 33c are operated, the rotation of the corresponding reels stops. Next, when all reels 33a to 33c stop spinning, a process is performed to award a predetermined number of game values ​​(add them to credits) according to the result of the game, or to allow the game to be restarted without consuming any more game values ​​(replay process), and one game ends. Also, when the counting button 212 is operated, a predetermined number of credits (game tokens) are sent (returned) to a dedicated unit. Then, when a card return operation is performed in the dedicated unit, a card with predetermined information stored on it is ejected from the dedicated unit 200.

[0095] Furthermore, when the game value in the gaming machine 101 is set to the bet state, operating (pressing) the settlement button 218 will return the betted game value to the credits. The settlement button 218 is operated when returning the game value that has been bet (set to the bet state) by operating the bet button 35 to the credits (game value memory area). In other words, based on the operation of the settlement button 218, a process (bet return process) is executed to return the game value set to the bet state to the credits. The bet return process is a process in which the bet state setting of the game value is cleared, and a value equivalent to the number of game values ​​that was set to the bet state is added to the number of credits (stored value in the game value memory area). When the settlement button 218 is operated while there is game value set to the bet state, the game value is returned to the credits based on that operation, and the number of game tokens displayed on the game token display device 211 increases.

[0096] The main control board is equipped with a setting change key cylinder and a setting change button. Note that the setting change key cylinder and setting change button may also be provided in other parts, such as the power supply unit. The setting change key cylinder (setting key switch) has two states: OFF and ON. In other words, it is possible to switch between the OFF and ON states. The setting change key cylinder is designed to accept a setting key. Initially, the setting change key cylinder is in the OFF state. When the inserted setting key is rotated 90 degrees clockwise from its initial position, the state of the setting change key cylinder switches from the OFF state to the ON state. When the setting key is rotated 90 degrees counterclockwise from the ON state position back to the initial position, the state switches from ON to OFF. The setting change button is also pressable.

[0097] The main control board receives input signals from input means such as the bet button 35, start lever 32, and stop buttons 33a to 33c, performs various calculations to execute the game, and controls output means such as the reel unit based on the calculation results.

[0098] The sub-control board receives signals from the main control board and input signals from input means such as the performance buttons 36, performs various calculations to execute the performance, and controls the performance devices such as the liquid crystal display 13 and speaker 14 based on the calculation results.

[0099] The main control board and the sub-control board are electrically connected, allowing the main control board to transmit various information (signals), such as information indicating the game status, to the sub-control board. However, the sub-control board cannot transmit information to the main control board. Furthermore, the functions of each board, including the main control board and sub-control board, are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, as well as software consisting of predetermined programs pre-stored in ROM, etc.

[0100] Conventional slot machines are equipped with a coin slot, a tray, a hopper unit, a cash box, etc., but the gaming machine 101 does not have any of these.

[0101] Figure 12 is a perspective view showing the inside of the enclosure 1. Inside the enclosure 1 is a power supply unit 210, which houses a power supply board (power supply means) for supplying power to each component. The power supply unit 210 is a roughly rectangular box shape and is located in the lower left of the inside of the enclosure 1 (placed on the bottom plate 4). The power supply unit 210 is equipped with a power switch (not shown), and when the power switch is turned ON, power is supplied from the power supply unit 210 to each component. Note that some components may be supplied with power even when the power supply unit 210 is OFF. Although not shown in the figure, a power cable (power harness) that connects to an outlet supplying commercial power (AC100V) is connected to a power connector provided on the power supply unit 210. Specifically, a connector provided on one end of the power harness is connected to the power connector, and a plug provided on the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 210 generates a DC power supply (for example, 5V, 12V, 24V, etc.) from power supplied from outside the gaming machine via a power harness, and supplies power to each component of the gaming machine.

[0102] Inside the enclosure 1, a gaming ball dispensing device connection terminal board 220 is mounted on the inner surface of the left panel 5. The gaming ball dispensing device connection terminal board 220 is a connection terminal board for connecting the gaming machine 101 and the dedicated unit. In other words, the gaming machine 101 and the dedicated unit are connected via the gaming ball dispensing device connection terminal board 220. One end of the terminal board harness 221 is connected to the connector of the gaming ball dispensing device connection terminal board 220, and the other end of the terminal board harness 221 is connected to the dedicated unit. The dedicated unit is connected to an external electronic device (such as a hall computer).

[0103] Similar to the gaming machine of the first embodiment, the gaming machine of this embodiment also has a metal sheet 40 attached to the inner surface of the housing 1 (for example, the back panel 3). Furthermore, the panel on which the sheet 40 is provided (hereinafter referred to as the back panel 3) is provided with a wiring opening 70 (first back panel opening) and a heat dissipation opening 80 (second back panel opening). The wiring opening 70 includes at least a wiring opening 71 for passing a power harness connected to the power supply unit 210, and a wiring opening 72 for passing a terminal board harness 221 connected to the gaming ball dispensing device connection terminal board 220.

[0104] The wiring opening 70 through which the harness passes has been processed in a specific way (e.g., counterbore processing), but the heat dissipation opening 80 through which the harness does not pass has not been processed in a specific way (e.g., counterbore processing). The wiring opening 70 on the inner side of the first back panel is larger (in diameter) than the opening on the outer side of the first back panel. The wiring opening 70 on the inner side of the back panel 3 (enclosure 1) is larger than the opening on the outer side of the back panel 3.

[0105] The sheet 40 has a sheet opening (for example, sheet opening 42 in Figure 6) that corresponds to the wiring opening 70. The sheet 40 also has a sheet opening (for example, sheet opening 44 in Figure 9) that corresponds to the heat dissipation opening 80.

[0106] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 (wiring opening 72 in Figure 6) with the first back panel inner side opening (first back panel inner side opening G in Figure 6) (by shifting the position of the edge of the sheet 40 outward), contact between the harness and the sheet 40 can be suppressed. Suppressing contact between the harness and the sheet 40 has the following effects: (1) When the harness comes into contact with the sheet 40, the edge of the sheet 40 may peel off (tear) a part of the sheet 40, and the peeled-off sheet 40 may come into contact with the circuit board inside the housing 1, causing a short circuit (component failure). Such problems can be suppressed. (2) When the edge (edge) of the harness and the sheet 40 come into contact (rub against each other), the harness may be damaged (the harness insulation may be torn), potentially leading to a break in the wire. Such problems can be suppressed. Furthermore, if the harness insulation peels off and the conductor becomes exposed, the possibility of the conductor coming into contact with the sheet 40 (and thus making electrical contact) can be reduced. According to this embodiment, it is possible to provide a gaming machine that combines the noise reduction effect of the sheet 40 with the effect of suppressing component damage (failure) through specific processing.

[0107] (Third embodiment) A third embodiment of the present invention will be described below with reference to the drawings. The gaming machine of this embodiment is a gaming machine 10 that uses game value as electronic information instead of game tokens (medals) as a game medium, and the game is played by consuming or assigning game value. The gaming machine 10 (Figure 13) is a so-called smart pachinko slot (registered trademark). Unlike conventional slot machines in which players insert physical tokens when playing and receive physical tokens when winning combinations are achieved, the gaming machine 10 is a gaming machine (medalless gaming machine) that uses game value as electronic information instead of physical tokens, and the game value is consumed or assigned through gameplay. In a medalless gaming machine, the game value corresponds to the tokens that represent the game value in conventional slot machines, and the game value in a medalless gaming machine can be understood as a virtual token (electronic token). Therefore, the game value in this embodiment may also be called a token (game token). Furthermore, in the following, the number of game values ​​may be considered as the number of virtual tokens, and the number of game values ​​may be indicated as "~ tokens" or "~ items".

[0108] In the following explanation, "front and back" basically means that when the player is in front of the gaming machine 10, the player's side is "front" and the gaming machine side is "back". "Up and down" means that the top surface of the gaming machine is "up" and the bottom surface is "down". "Left and right" means that the left hand side of the player playing the gaming machine is "left" and the right hand side is "right".

[0109] Figure 13 is a perspective view of the gaming machine 10 as seen from the front. As shown in Figure 13, the gaming machine 10 of this embodiment comprises a box-shaped housing 11 with an open front side facing the player, and a front door 12 that opens and closes the front opening of the housing 11. The front door 12 is rotatably connected via a hinge and opens and closes the opening of the housing 11. The front door 12 is divided into an upper door 12a and a lower door 12b, and these upper door 12a and lower door 12b can be opened and closed relative to the housing 11. The front door 12 may also be a single integrated structure that is not divided into an upper door 12a and a lower door 12b.

[0110] The enclosure 11 is formed in a box shape with an open front (having a front opening). The enclosure 11 comprises a top plate 2, a back plate 3, a bottom plate 4, and left and right side plates 5 and 6. The left side plate 5 is referred to as the left side plate 5, and the right side plate 6 is referred to as the right side plate 6. In this embodiment, the top plate 2, back plate 3, bottom plate 4, left side plate 5, and right side plate 6 are made of resin. However, at least some of the plates may be made of a material other than resin (such as metal or wood). In this embodiment, the inner surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 facing the inside of the enclosure 1 are referred to as "inner surfaces." The bottom surface of the top panel 2, the front surface of the back panel 3, the top surface of the bottom panel 4, the right surface of the left panel 5, and the left surface of the right panel 6 are "inner surfaces." Also in this embodiment, the outer surfaces of the top panel 2, back panel 3, bottom panel 4, left panel 5, and right panel 6 facing the outside of the enclosure 1 are referred to as "outer surfaces." The top surface of the top panel 2, the back surface of the back panel 3, the bottom surface of the bottom panel 4, the left surface of the left panel 5, and the right surface of the right panel 6 are "outer surfaces."

[0111] A liquid crystal display 13 (display means) is provided approximately in the center of the upper door 12a as a performance device. The liquid crystal display 13 displays various images (performance images) to assist or enhance the game. A speaker 14 (sound output means) is provided on the lower door 12b as a performance device. The speaker 14 outputs various performance sounds (music, sound effects, voices, etc.) to assist or enhance the game. A lamp 38 (lighting device, lighting means, outer perimeter lamp) is provided on the front door 12 for notification and performance purposes. In addition, movable parts that can be operated by actuators, etc., may be provided as performance devices.

[0112] Furthermore, a display window 16 is provided on the upper door 12a. Behind the display window 16 (the first display area 13a, described later), the reel unit is positioned so that a portion of it can be seen through the display window 16. Each reel 20a to 20c has its outer surface divided into 20 sections (20 areas) at regular intervals, and one of several types of symbols is placed in each section. In other words, multiple types of symbols are arranged in a row on the outer surface of each reel 20a to 20c. When each reel 20a to 20c stops, three symbols per reel (upper, middle, and lower) are displayed through the display window 16. The display window 16 is also provided with upper, middle, and lower sections as display positions for viewing the symbols of each reel 20a to 20c, and the number of active lines is set by the combination of the display positions of each reel 20a to 20c. In this embodiment, the effective line is composed of the upper section of the first reel 20a, the middle section of the second reel 20b, and the lower section of the third reel 20c.

[0113] In this embodiment, the number of game values ​​required for one game (specified number, specified number of tokens) is set to 3, and when the specified number of game values ​​is inserted, the active lines are activated. As the game starts, each reel 20a to 20c starts to rotate and an internal lottery is performed to determine whether one of the winning combinations is won or lost (not won). Next, when the reels 20a to 20c stop, if the symbol combination corresponding to the winning combination determined by the internal lottery is displayed on the active line, this winning combination is awarded, and the processing corresponding to the awarded winning combination (award processing) is performed. In other words, whether or not a winning combination has been awarded is indicated by the symbol combination displayed through the display window 16 when the reels 20a to 20c stop. The active lines can be said to be lines for determining whether a winning combination has been awarded.

[0114] The liquid crystal display 13 is positioned in front of the reel unit, which is equipped with reels 20a to 20c. The liquid crystal display 13 can perform effects by displaying predetermined displays (display objects) on its display surface. Display objects refer to things like people, animals, vehicles, buildings, natural objects (e.g., rocks, trees, etc.), characters, backgrounds, patterns, designs, and other things (images) that are displayed on the liquid crystal display 13. The liquid crystal display 13 has a display area that is outside the reels (second display area 13b), which is a display area that does not overlap with the reels 20a to 20c when viewed from the front, and a display area in front of the reels (first display area 13a), which overlaps with the reels 20a to 20c when viewed from the front. The second display area 13b is formed to surround the first display area 13a. The liquid crystal display 13 is a transmissive liquid crystal display, and is designed to make components behind the first display area 13a (transparent area) visible. The first display area 13a has multiple states, including a transparent state and a state in which a display object (animation image) is displayed (transparent display state). When the first display area 13a is transparent, the patterns on the reels 20a to 20c are visible. When the first display area 13a is in the state in which a display object is displayed, the animation image is displayed in front of the reels 20a to 20c. In the state in which the first display area 13a is in the state in which a display object is displayed, there may be a state in which the patterns on the reels 20a to 20c are visible (easily visible) and a state in which they are not visible (difficult to see). Thus, the first display area 13a is an area in which the patterns on the reels 20a to 20c are visible and an animation image can be displayed. In Figure 13, the first display area 13a is shown to consist of three divided regions, but it is not limited to this and may be a single horizontally elongated rectangular region.

[0115] The second display area 13b is the portion of the liquid crystal display 13's display area excluding the first display area 13a. The second display area 13b can display images for special effects. It is also possible to display a single, cohesive image spanning both the second display area 13b and the first display area 13a. The second display area 13b is not transparent and cannot be used to allow visibility of components behind it. The liquid crystal display 13 does not have to be a transmissive liquid crystal display, and the reels 20a to 20c do not necessarily have to be visible through the liquid crystal display 13 (first display area 13a). In other words, the display window 16 may be made of a transparent panel (which cannot display any objects), and the reels 20a to 20c may be visible through that display window 16.

[0116] Although not shown in Figure 13, a game information display unit is provided below the display window 16. The game information display unit consists of LEDs, lamps, a 7-segment display, etc., and displays various game information such as the number of game values ​​paid out in a single game and error information. The game information display unit includes a first main display, a second main display, and a sub-display. The game information display unit may also include a favorable section display.

[0117] The lower door 12b (operation panel) is equipped with a bet button 23 operated when betting (inserting) game value, a start lever 24 (game start operation means) operated when starting the game, a stop button 26 (stop operation means) (stop buttons 26a, 26b, 26c) operated when stopping the rotating reels, and an effect button 25 (effect operation means) operated when advancing the effects, etc. The bet button 23 may also include a MAX bet button (first bet button) operated when betting 3 (predetermined number) game value and a 1 bet button (second bet button) operated when betting 1 game value.

[0118] The performance button 25 (performance operation means) is operated when advancing the performance (changing the manner of the performance), etc. The performance button 25 is formed to be pressable, and when pressed, the manner of the performance image displayed on the liquid crystal display 13 changes, for example. By providing the performance button 25 and enabling its operation at predetermined triggers, it is possible to increase the player's sense of participation in the game and improve the enjoyment of the game. For example, the performance button 25 becomes operational when a performance is being executed that makes the player expect to transition to a favorable state, and an image instructing the operation (PUSH image) is displayed on the liquid crystal display 13 (PUSH performance). When the performance button 25 is operated, the result of the game (for example, whether or not a favorable state is transitioned) is announced. Note that the performance button 25 is not limited to the shape of a button, but may also be in the shape of a lever, etc., as long as it is configured to be able to detect the player's operation.

[0119] Furthermore, a door key cylinder 69 is provided on the lower door 12b. The lower door 12b (front door 12) can be unlocked by inserting a door key into the door key cylinder 69. Specifically, the lower door 12b can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 69 clockwise from its initial position. Alternatively, an error can be cleared by rotating (twisting) the door key inserted into the door key cylinder 69 counterclockwise from its initial position.

[0120] Furthermore, a lower panel 91 is provided on the lower door 12b. A light source (LED) for illumination is provided on the back side of the lower panel 91, and the lower panel 91 is illuminated from behind by the light emitted from this light source.

[0121] As shown in Figure 14, a reel unit 31 is provided inside the housing 11. The reel unit 31 includes three reels 20a, 20b, and 20c displaying multiple patterns around their periphery, a drive motor (stepping motor) for rotating the reels 20a to 20c, and index sensors provided corresponding to the reels 20a to 20c. Each reel is fixed to the output shaft of the respective stepping motor. The stepping motors are four-phase stepping motors. Each stepping motor comprises a rotor and a stator having a first-phase coil, a second-phase coil, a third-phase coil, and a fourth-phase coil. Each stepping motor is excited by 1-2 phase excitation, which alternates between supplying a 1-phase excitation pulse to turn on one coil and supplying a 2-phase excitation pulse to turn on one coil and the other adjacent coils. Each step update of the excitation pulse results in a displacement of half a step angle (1 step angle for every 2 steps update), and 504 steps update (252 step angle displacement) completes one rotation of each reel 20a-20c. The stepping motor has a step angle of approximately 1.43° and an interrupt time t for updating the excitation pulse by one step of 1.49 ms. In addition, each index sensor detects the edge of a semicircular index attached to the inside of each reel 20a-20c. Based on the detection information from these index sensors, control is performed for the rotation and stopping of the reels 20a-20c.

[0122] A power supply unit 32, which houses a power supply device (power supply means) for supplying power to each component, is provided on the upper surface of the bottom plate 4 inside the housing 11. The power supply unit 32 is a roughly rectangular box shape and is located in the lower left inside the housing 1 (placed on the bottom plate 4) and fixed to the inner surface of the left side plate 5. The power supply unit 32 is equipped with a power switch, and when the power switch is turned ON (on state), power is supplied from the power supply unit 32 to each component. Note that some components may be supplied with power even when the power supply unit 32 is OFF (disconnected state). A power connector (not shown) provided on the back of the power supply unit 32 is connected to a power cable (power harness) that connects to an outlet supplying commercial power (AC100V). Specifically, a connector provided at one end of the power harness is connected to the power connector, and a plug provided at the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 32 generates a DC power supply (for example, 5V, 12V, 24V, etc.) from power supplied from outside the gaming machine via a power harness, and supplies power to each component of the gaming machine.

[0123] As shown in Figure 15, a dedicated unit 200 (specific unit, game value lending device) is provided on the side (right side) of the gaming machine 10 as a device for lending game value (capable of performing control related to the lending of game value). The gaming machine 10 and the dedicated unit 200 are connected via a harness, which will be described later, and are able to communicate with each other. The front of the dedicated unit 200 is provided with a banknote slot 201 into which banknotes can be inserted, a card insertion / discharge slot 202 into which cards (game value management media) can be inserted / discharged, a lending button 203 (lending operation means), a replay button 204 (lending operation means), and a card return button 205, etc. The card is used to manage the number of game value owned by the player. In other words, the number of game value owned by the player can be ascertained by the card. The card may also be capable of storing a prepaid balance. Furthermore, the management of the number of game values ​​using cards may be carried out by storing the number of game values ​​on the card itself, or by storing the number of game values ​​in a designated management device installed in the gaming hall, etc., and linking the number of game values ​​stored in the management device, etc. with the identification information stored on the card (such as the player's ID or the unique identification number for each card).

[0124] In the dedicated unit 200, an operation (press operation) on the lending button 203 is accepted as a lending operation (game value transfer operation) that transfers game value to the gaming machine 10. When the lending button 203 is pressed, the stored value, etc., that is stored as a prepaid balance in the banknotes or cards inserted into the banknote slot 201 is consumed, and a predetermined number (for example, 50) of game value is credited to the gaming machine 10. In addition, in the dedicated unit 200, an operation (press operation) on the replay button 204 is accepted as a lending operation (game value transfer operation) that transfers game value to the gaming machine 10. When the replay button 204 is pressed, the game value owned by the player, which is managed by the card (game value linked to the card), is consumed, and a predetermined number (for example, 50) of game value is credited to the gaming machine 10. In other words, in this embodiment, an operation on the loan button 203 or the replay button 204, which are loan operation means, is accepted as a loan operation (game value transfer operation), and based on the loan operation, a predetermined number of game values ​​are transferred (loaned) from the dedicated unit 200 to the game machine 10.

[0125] As shown in Figure 13, the lower door 12b is equipped with a game token count display device 211 (game value count display device, game value indicator), a counting button 212, and a payout button 218. The game token count display device 211 and the counting button 212 are located on the side (right side) of the lower door 12b. Based on the lending operation in the dedicated unit 200, the gaming machine 10 sets a value equivalent to a predetermined number of game values ​​as credits. The number of credits (the number of game tokens available for play) is displayed on the game token count display device 211. The game token count display device 211 has a 5-digit (or 6-digit) 7-segment display, and the number of credits is displayed on this 7-segment display. In the gaming machine 10, the upper limit of the number of credits may be set, for example, within the range of values ​​that can be displayed on the game token count display device 211. In the gaming machine 10, when the bet button 23 is operated while the game value is stored in credits, the stored game value is set to the payout state up to a predetermined limit.

[0126] The gaming machine 10 is equipped with various boards, including a main control board (main control means) that controls the progress of the game, a sub-control board (sub-control means) that controls the effects according to the progress of the game, and a game value control board (game value control means) that controls the game value.

[0127] The main control board receives input signals from input means such as the bet button 23, start lever 24, and stop button 26, performs various calculations to execute the game, and controls output means such as the reel unit 31 based on the calculation results. The main control board is also equipped with a setting change key cylinder and setting change buttons. Note that the setting change key cylinder and setting change buttons may be provided, for example, in the power supply unit 32.

[0128] The sub-control board receives signals (information) from the main control board, performs various calculations to execute the performance, and controls various performance devices such as the liquid crystal display 13 and speaker 14 based on the calculation results.

[0129] The main control board and the sub-control board are electrically connected, and the main control board can transmit various information (signals), such as information indicating the game status, to the sub-control board. However, the sub-control board cannot transmit information to the main control board. The functions of each board, such as the main control board and sub-control board, are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, and software consisting of predetermined programs pre-stored in ROM, etc. The main control board and the game value control board are electrically connected and capable of bidirectional communication. The game value control board may be integrally formed with the main control board.

[0130] The game value control means increases the number of credits by a predetermined number based on the occurrence of a predetermined role (minor role) and the awarding of a predetermined number of game values. Furthermore, when an operation to insert game values ​​(operation of the bet button 23) is performed at the start of the game, the game value control means decreases the number of credits by the amount of game value inserted. At this time, the game medal display device 211 displays a value obtained by subtracting the number of bets from the number of held medals (number of credits).

[0131] The game value control means controls the reception of game value transferred from the dedicated unit 200 to the game machine 10. When game value is transferred from the dedicated unit 200 to the game machine 10, the game value control means increases the number of credits by the amount of game value being transferred. The game value control means also controls the transfer of game value from the game machine 10 to the dedicated unit 200. When game value is transferred from the game machine 10 to the dedicated unit 200, the game value control means decreases the number of credits by the amount of game value being transferred. The game value control means also displays the number of game values ​​stored as credits (number of credits) on the game medal display device 211 and changes the display content of the game medal display device 211 according to the increase or decrease in the number of credits.

[0132] The counting button 212 is operated when sending (returning, transferring) information (credits) indicating a value equivalent to a predetermined number of credits (all or part of the number of credits) to the dedicated unit 200. The counting button 212 is equipped with a press part (operation part), and the press part is formed to be pressable. When a player finishes playing, etc., the credited game value can be transferred from the game machine 10 to the dedicated unit 200 based on an operation (press operation) of the counting button 212 as a counting operation (return operation). Then, after the game value has been transferred to the dedicated unit 200, when an operation (press operation) of the card return button 205 (Figure 15) is performed, a card that allows the player to know the number of game values ​​they possess is ejected from the dedicated unit 200 (card insertion / discharge port 202).

[0133] Based on the lending operation in the dedicated unit 200, a predetermined number of game value (game tokens) is assigned to the game machine 10 (credits are added). Next, when the bet button 23 is operated, the game value is set to the input state up to a predetermined limit, and a value equivalent to the number of game value (game tokens) set to the input state is subtracted from the credits. In other words, the number of game value displayed on the game token display device 211 decreases.

[0134] When a predetermined number of game values ​​are set to the input state, the start lever 24 becomes operational, that is, it becomes possible to start playing. Next, when the game start operation is performed on the activated start lever 24, the rotation of each reel 20a to 20c begins. Next, when the rotation speed of the reels increases to a predetermined speed and enters a steady rotation state, the operation of the stop buttons 26a to 26c becomes operational. Next, when the activated stop buttons 26a to 26c are operated, the rotation of the corresponding reel stops. Next, when the rotation of all reels 20a to 20c stops, depending on the result of the game, a process is performed to award a predetermined number of game values ​​(add to credits), or a process is performed to make it possible to start playing again without consuming new game values ​​(replay process), and one game (1 play) ends. Also, when the counting button 212 is operated, a predetermined number of credits (game tokens) are sent (returned) to the dedicated unit 200. Then, when the card return operation is performed in the dedicated unit 200, the card with the predetermined information stored on it is ejected from the dedicated unit 200.

[0135] Furthermore, when the game value in the gaming machine 10 is set to the bet state, operating (pressing) the settlement button 218 will return the betted game value to the credits. The settlement button 218 is the button that is operated when returning the game value that has been bet (set to the bet state) by operating the bet button 23 to the credits. In other words, based on the operation of the settlement button 218, a process (bet return process) is executed to return the game value set to the bet state to the credits. The bet return process is a process in which the bet state setting of the game value is cleared, and a value equivalent to the number of game values ​​that was set to the bet state is added to the number of credits. When the settlement button 218 is operated while there is game value set to the bet state, the game value is returned to the credits based on that operation, and the number of game tokens displayed on the game token display device 211 increases.

[0136] In the gaming machine of this embodiment, the main frame unit 150 shown in Figure 16 is detachably attached to the inside of the housing 11. The main frame unit 150 comprises a frame 151 (main frame), and various components (various circuit boards including the main control board and the reel unit 31) are supported (fixed) to the frame 151 to form a unit. Hereinafter, when referring to the reel unit 31, it may include members that directly or indirectly support each reel (which may be part of the frame 151).

[0137] Although not shown in the diagram, the main control board and the game value control board are connected via a harness. Furthermore, the game value control board and the game ball dispensing device connection terminal board 35 (Figure 17) are also connected via a harness.

[0138] Figure 17 is a front perspective view of the gaming ball dispensing device connection terminal board 35, which is located inside the housing 11. The gaming ball dispensing device connection terminal board 35 (specific circuit board) is fitted with a transparent resin case, and the circuit board is housed (sealed) in the case. The gaming ball dispensing device connection terminal board 35 is also fitted with a connector 36 (first connector, female connector) (the connector 36 is mounted on the circuit board). The connector 36 is exposed through an opening provided in the case.

[0139] The gaming machine 10 (game value count control board) is connected to the dedicated unit 200 via a game ball dispensing device connection terminal board 35 located inside the casing 11. The game ball dispensing device connection terminal board 35 is a connection terminal board for connecting the gaming machine 10 (game value count control board) and the dedicated unit 200. The dedicated unit 200 transmits signals related to the dispensing of game value to the gaming machine 10. The gaming machine 10 transmits various external signals indicating the status of the gaming machine, the results of receiving game value dispensing, signals related to the counting of game value, etc., to the dedicated unit 200. The dedicated unit 200 can output the external signals received from the gaming machine 10 to external devices (electronic devices: data display devices, hall computers, etc.).

[0140] Figure 18(a) is a perspective view showing the inside (lower right) of the housing 11. Figure 18(a) shows the state with the main frame unit 150 removed. The game ball dispensing device connection terminal board 35 is fixed to the inner surface of the back plate 3 by screws or the like. The game ball dispensing device connection terminal board 35 is located near the center in the left-right direction (slightly to the right of the center) and near the center in the up-down direction (slightly below the center). Below the game ball dispensing device connection terminal board 35, a game value count control board unit 37 is provided. The game value count control board unit 37 includes a game value count control board and a transparent resin case that houses the game value count control board.

[0141] Figure 18(b) shows the state in Figure 18(a) where the harness 39 is connected to the connector 36 of the gaming ball dispensing device connection terminal board 35. Connector 36 is connected to connector 39a (second connector, male connector) provided at one end of harness 39. Harness 39 (wiring, cable) has a connector 39a at one end that connects to the gaming ball dispensing device connection terminal board 35, and a connector (not shown) at the other end that connects to the dedicated unit 200. This connector (the connector at the other end) is connected to the dedicated unit 200.

[0142] The back plate 3 is provided with at least one through-hole that penetrates in the front-to-back direction, one of which is a specific through-hole 38. The specific through-hole 38 is located on the right side in the left-to-right direction (towards the right-side plate 6) and near the center in the up-to-down direction (slightly below the center). The specific through-hole 38 is located on the dedicated unit 200 side of the gaming ball dispensing device connection terminal board 35 and is located to the right (upper right) of the gaming ball dispensing device connection terminal board 35. In other words, the specific through-hole 38 is located between the gaming ball dispensing device connection terminal board 35 and the dedicated unit 200. The specific through-hole 38 is a hole for passing the harness 39 through. By providing the specific through-hole 38 for the harness 39 to pass through in this position, the length of the harness 39 can be shortened compared to when the through-hole for the harness 39 is provided in another position (for example, to the left of the gaming ball dispensing device connection terminal board 35). This reduces costs.

[0143] The specific through-hole 38 is a horizontally elongated rectangular hole when viewed from the front (front-to-back direction). The specific through-hole 38 has a width (longitudinal dimension) of approximately 43 mm and a height (shortitudinal dimension) of approximately 22 mm. A worker standing on the front side of the gaming machine 10 (casing 11) visually confirms the specific through-hole 38 from the front side (front side) and reaches their hand from the right outside of the gaming machine 10 (casing 11) to the rear (back side), passing the harness 39 through the specific through-hole 38 from the rear (back side). Next, from the front side (inside the casing 11), the connector 39a is fitted into the connector 36 of the gaming ball dispensing device connection terminal board 35.

[0144] Figure 19 shows the connector 39a as viewed from the mating direction (terminal side). When viewed from the mating direction (terminal side), the connector 39a has a roughly rectangular shape, with a width (longitudinal dimension) of approximately 33 mm and a height (short dimension) of approximately 14 mm. The state shown in Figure 19 is assumed to be when the connector 39a is oriented horizontally. When the connector 39a is oriented horizontally (aligned with the orientation of the specific through-hole 38 (longitudinal direction)), it can pass through the specific through-hole 38. However, when the connector 39a is rotated approximately 90° to become vertical (rotated approximately 90° clockwise or counterclockwise on the plane of the paper), it cannot pass through the specific through-hole 38. The specific through-hole 38 is sized to allow the horizontally oriented (predetermined orientation) connector 39a to pass through, but not the vertically oriented (orientation rotated 90° relative to the predetermined orientation) connector 39a to pass through.

[0145] If the specific through-hole 38 is formed to a size that allows the connector 39a to pass through regardless of its orientation, the relatively large size of the specific through-hole 38 can lead to problems such as increased risk of foreign objects entering the housing 11 and component failure, and reduced anti-tampering performance due to easier access to the inside of the housing 11. Furthermore, because the specific through-hole 38 is large, the harness 39 can move more easily (become more unruly) inside the specific through-hole 38, resulting in a reduced function of restricting the movement of the harness 39. In this embodiment, the specific through-hole 38 is made large enough to allow a horizontally oriented connector 39a to pass through, but not large enough to allow a vertically oriented connector 39a to pass through, thus avoiding unnecessary size. Therefore, the problems resulting from the large size of the specific through-hole 39 can be suppressed.

[0146] In this embodiment, the specific through-hole 38 is made into a horizontally elongated rectangle when viewed from the front, allowing a horizontally oriented connector 39a to pass through but preventing a vertically oriented connector 39a from passing through. However, the embodiment is not limited to this, and the specific through-hole 38 may also be made into a vertically elongated rectangle when viewed from the front, allowing a vertically oriented connector 39a to pass through but preventing a horizontally oriented connector 39a from passing through.

[0147] Figure 20 is a front view (front perspective) showing a part of the interior (lower right) of the housing 11. Figure 20 shows the state before the harness 39 is connected.

[0148] A reel unit 31 (including the support member (frame) for the reel unit 31) is located in front of (towards) the gaming ball dispensing device connection terminal board 35. When the housing 11 is viewed from the front (in a front view) (when facing the housing 11 directly), the reel unit 31 and a portion (upper half) of the gaming ball dispensing device connection terminal board 35 overlap. As a result, in a front view, a portion (upper half) of the gaming ball dispensing device connection terminal board 35 is hidden by the reel unit 31 and cannot be seen, while a portion (lower half) of the gaming ball dispensing device connection terminal board 35 is not hidden by the reel unit 31 and can be seen. In a front view, the connector 36 of the gaming ball dispensing device connection terminal board 35 is not hidden by the reel unit 31 and can be seen. As a result, the worker can easily connect the harness 39 to the connector 36.

[0149] Although not shown in the diagram, the gaming ball dispensing device connection terminal board 35 is equipped with a horizontally elongated rectangular sticker attached to the underside of the connector 36. This sticker is not hidden by the reel unit 31 and is visible from the front. The sticker has information such as the part name (gaming ball dispensing device connection terminal board) and identification information (management number, etc.) printed on it. Therefore, the operator can easily check the information printed on the sticker from the front.

[0150] A reel unit 31 (including a support member (frame) for the reel unit 31) is located in front of (towards) the specific through-hole 38. When the housing 11 is viewed from the front (in a front view) (when facing the housing 11 directly), the reel unit 31 and a portion of the specific through-hole 38 overlap. As a result, in a front view, a portion of the specific through-hole 38 (dashed line portion) is hidden by the reel unit 31 and cannot be seen. In this embodiment, the specific through-hole 38 is located in a position where, when the housing 11 is viewed from the front (when viewed from the front), there is a portion that overlaps with the reel unit 31 and is not visible, and a portion that does not overlap with the reel unit 31 and is visible.

[0151] Here, we consider the case where the specific through-hole 38 is provided in a position where, when the housing 11 is viewed from the front, there is no overlap with other components (reel unit 31) provided on the front side. In this case, the entire specific through-hole 38 is visible when viewed from the front, making it easy to pass the harness 39 (connector 39a) through the specific through-hole 38. However, this would reduce the space available for other shapes (components) on the back plate 3 of the housing 11, creating limitations (constraints) on the design of the back plate 3 and reducing the degree of design freedom. There are circumstances where it is difficult to provide the specific through-hole 38 in a position where it is fully visible when viewed from the front, depending on its positional relationship with the surrounding components (shapes).

[0152] In order to minimize the constraints imposed on the design of the back plate 3 (to ensure design freedom), it is necessary to allow a partial overlap (partial overlap) between the reel unit 31 and the specific through-hole 38 when viewed from the front. In this embodiment, the specific through-hole 38 has a range that overlaps with the reel unit 31 and is not visible when the housing 11 is viewed from the front (when viewed from the front), and a range that does not overlap with the reel unit 31 and is visible. This makes it possible to minimize the constraints on the design of the back plate 3 while ensuring the visibility of the specific through-hole 38 from the front side and preventing a decrease in the workability of passing the harness 39 (connector 39a) through the specific through-hole 38.

[0153] Incidentally, if the overlapping area between the reel unit 31 and the specific through-hole 38 is too large, it becomes difficult to see the harness 39 (connector 39a) from the front, reducing the work efficiency of passing the harness 39 (connector 39a) through the specific through-hole 38. Also, the work efficiency of checking whether or not the harness 39 has passed through the specific through-hole 38 is reduced. For this reason, it is necessary to set the size of the overlapping area between the reel unit 31 and the specific through-hole 38 to an appropriate size. In this embodiment, when the housing 11 is viewed from the front, the size of the overlapping area between the reel unit 31 and the specific through-hole 38 is less than half the size of the specific through-hole 38. The size of this overlapping area may be about one-third the size of the specific through-hole 38. Therefore, when the housing 11 is viewed from the front, more than half (at least half) of the specific through-hole 38 does not overlap with the reel unit 31 and is visible. This helps to suppress the reduction in work efficiency.

[0154] Figure 21(a) shows the connector 39a being passed through the specific through-hole 38 from the rear. In this embodiment, there is a non-overlapping area between the reel unit 31 and the specific through-hole 38, so at least a portion of the connector 39a is visible from the front when passing the connector 39a through the specific through-hole 38. When the housing 11 is viewed from the front, the size (width) of the overlapping area between the reel unit 31 and the specific through-hole 38 is less than the width (longitudinal dimension) of the connector 39a.

[0155] Figure 21(b) shows the state in which the connector 39a (harness 39) is passed through the specific through-hole 38 and the connector 39a is fitted into the connector 36 of the gaming ball dispensing device connection terminal board 35. In this embodiment, since there is a range in which the reel unit 31 and the specific through-hole 38 do not overlap, it is possible to visually confirm from the front that the harness 39 is passing through the specific through-hole 38. In other words, it is possible to check from the front whether or not the harness 39 is passing through the specific through-hole 38.

[0156] In this embodiment, it can also be said that the specific through-hole 38 is enlarged to a size that does not overlap with other members when viewed from the front.

[0157] In this embodiment, when the housing 11 is viewed from the front, if the shortest distance between the right end of the reel unit 31 (support portion) and the left end of the metal fitting (metal member) provided on the right side plate 6 is defined as distance S (see Figure 21(a)), then distance S is smaller than the width of the connector 39a.

[0158] In this embodiment, the reel unit 31 is provided as a member (referred to as the specific member) that is positioned in front of the specific through-hole 38 in a front view and overlaps with a portion of the specific through-hole 38. However, the specific member (the member that reduces the visibility of the specific through-hole 38) is not limited to the reel unit 31 and may be any other member. Examples of the specific member include a circuit board unit housing a predetermined circuit board, a clamp member (harness retaining member) capable of supporting (fixing) a predetermined harness, and a door sensor capable of detecting the opening and closing of the front door 12. The specific member may also be provided on the right side plate 6. The specific member is positioned away from the specific through-hole 38 in the front-rear direction. In other words, the specific through-hole 38 and the specific member are positioned at different locations in the front-rear direction, and the specific member is positioned in front of the specific through-hole 38.

[0159] In this embodiment, when the housing 11 is viewed from an oblique angle (for example, from above), there may be no member overlapping the specific through-hole 38, and the entire specific through-hole 38 may be visible. The specific through-hole 38 may be configured so that the entire hole is visible when the line of sight is shifted and viewed from an oblique angle. That is, the specific through-hole 38 may be partially obscured by a specific member when viewed from the front, but may be fully visible when viewed from a predetermined angle different from the front view.

[0160] The gaming machine of this embodiment is A gaming machine capable of communicating with a specific unit (dedicated unit 200) that can perform control related to the lending of gaming value, The system comprises a housing (housing 11) and a specific circuit board (a terminal board for connecting game balls, etc., to the dispensing device 35) located inside the housing, The enclosure comprises a top plate (top plate 2), a back plate (back plate 3), a bottom plate (bottom plate 4), and side plates (left side plate 5, right side plate 6). The back plate is provided with a specific through hole (specific through hole 38), A specific member (for example, a reel unit 31) is positioned in front of the aforementioned specific through-hole. The aforementioned specific substrate is connected to the aforementioned specific unit via wiring (harness 39) passed through the aforementioned specific through-hole. The aforementioned specific through-hole is provided in a position where, when the housing is viewed from the front, there is a range that overlaps with the specific member and is not visible, and a range that does not overlap with the specific member and is visible.

[0161] The specified through-hole is positioned such that, when the housing is viewed from the front, there is a range that overlaps with the specified member and is not visible, and a range that does not overlap with the specified member and is visible. Allowing partial overlap between the specified through-hole and the specified member provides greater design flexibility for the back panel than if the specified through-hole were provided without allowing overlap. Furthermore, the existence of a range where the specified through-hole and the specified member do not overlap when the housing is viewed from the front ensures visibility of the specified through-hole from the front. This helps to prevent a decrease in the work efficiency when routing the wiring through the specified through-hole.

[0162] Furthermore, the gaming machine of this embodiment is When the housing is viewed from the front, the area where the specific through-hole and the specific member overlap is less than half the size of the specific through-hole. When the housing is viewed from the front, the area where the specific through-hole and the specific member do not overlap is half or more the size of the specific through-hole. Therefore, the visibility of the specific through-hole is ensured, and the work of passing the wiring through the specific through-hole can be easily performed.

[0163] Furthermore, in the gaming machine of this embodiment, The aforementioned specific substrate is equipped with a first connector, The wiring includes a second connector connected to the first connector, The specified through-hole can allow the second connector to pass through in a predetermined orientation, but it cannot pass through the second connector when it is rotated 90° from the predetermined orientation. This prevents problems that would occur if the size of the specified through-hole were large enough to allow the second connector to pass through regardless of its orientation, such as an increased risk of component failure due to foreign matter intrusion, reduced anti-tampering performance, and a decrease in the function of restricting harness movement.

[0164] In Figure 20, a crimped portion is provided on the lower part of the game value control board unit 37 (the area enclosed by the thick dashed line). The board case of the game value control board unit 37 is sealed and cannot be opened unless the crimped portion (seal) is destroyed. In this embodiment, when the housing 11 is viewed from the front, no specific component is placed in front of the crimped portion, making the crimped portion visible. Therefore, workers can easily check for any irregularities (whether or not the crimped portion has been destroyed).

[0165] Furthermore, the present invention is not limited to the embodiments described above, and can be implemented in various modified forms without departing from its essence. Within the scope of the invention, the present invention allows for free combination of each embodiment, modification of any component of each embodiment, or omission of any component in each embodiment. For example, the configuration of the gaming machine is not limited to that of the embodiments described above. Moreover, the configurations described above can be applied to other gaming machines (e.g., pachinko machines). [Explanation of Symbols]
