Description

[Technical Field]

[0001] The present invention relates to gaming machines such as slot machines and pachinko machines. [Background technology]

[0002] Conventionally, typical examples of gaming machines include slot machines and pachinko machines. For example, slot machines and pachinko machines are equipped with speakers for emitting various gaming sounds forward from the front door of the gaming machine (see, for example, Patent Document 1). The speaker is installed inside a speaker grill that has multiple holes in the front door body, and since there is a concern that unauthorized access to the inside of the housing may be gained by piercing the speaker with a wire or the like, a back cover is attached to the back side of the speaker to prevent such unauthorized access. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-51472 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional back covers have a small opening that connects the inside of the back cover to the inside of the housing, making it difficult to ensure the speaker's sound quality and sound pressure.On the other hand, if the opening is made larger, it becomes easier for unauthorized access to occur through the opening, which is problematic from the perspective of preventing fraud.

[0005] An object of the present invention is to provide a gaming machine that can prevent unauthorized access to the inside of the cabinet and can ensure appropriate sound quality and sound pressure from the speakers. [Means for solving the problem]

[0006] That is, the invention described in claim 1 is as follows: A gaming machine comprising a cabinet and a front door provided on the front side of the cabinet, the front door having a speaker, the front door has a door body supported on the housing so as to be openable and closable; The speaker is fixed to the inner surface of the door body, and the rear side of the speaker is covered with a rear cover, the rear cover has at least a base portion fixed to an inner surface of the door body and a cylindrical portion extending from the base portion toward the inside of the housing, The cylindrical portion is provided with a plurality of openings arranged in a circumferential direction thereof and opening into the interior of the door main body, and a communication passage that connects the plurality of openings with an internal space of the rear cover, The communication passage is formed in a crank shape that is bent at least twice, the cylindrical portion has first wall portions and second wall portions that are alternately arranged in a circumferential direction, the communication passage is provided between the first wall portion and the second wall portion, and the first wall portion and the second wall portion have cross-sectional shapes that are different from each other, the communication passage is formed in a crank shape that is line-symmetrical with respect to the first wall portion, and a plurality of the communication passages are provided side by side in a circumferential direction, the rear cover has an extension cylindrical portion that extends from the cylindrical portion toward the inside of the housing and surrounds a rear end portion of the speaker, The extension cylindrical portion is formed to have a small-diameter cylindrical portion having an outer diameter smaller than that of the cylindrical portion, and a flange portion that is bent radially inward from a rear end portion of the small-diameter cylindrical portion and that fits along the rear end portion of the speaker. This is a gaming machine characterized by the above. [Effects of the Invention]

[0007] In this gaming machine according to the present invention, the rear cover covering the rear side of the speaker has a base portion and a cylindrical portion, and is provided with a communication passageway that connects the multiple openings in the cylindrical portion with the internal space of the rear cover, and the communication passageway is formed in a crank shape that is bent at least twice, so that even if someone tries to illegally access the inside of the cabinet through the speaker using a wire or the like, the wire or the like cannot pass through the communication passageway that is bent more than twice, thereby preventing fraudulent acts. Furthermore, because the internal space of the rear cover and the internal space of the door body are connected by the multiple openings and communication passageway, the sound quality and sound pressure of the speaker can be ensured to be appropriate.

DETAILED DESCRIPTION OF THE INVENTION

[0009] A first embodiment of the present invention will be described below with reference to the accompanying drawings. The following describes an embodiment in which the present invention is applied to a reel-type gaming machine, which is one type of gaming machine, specifically a slot machine 10. Figure 1 is a rear view of the front door of the slot machine 10.

[0010] [Overall structure of the gaming machine] The slot machine 10 has a housing that forms its outer shell. The housing is formed by assembling wooden panels into a box shape with an open front, and is attached to so-called island equipment by nailing or the like when installed in an amusement hall. Note that the housing is not limited to being made of wooden panels, but may also be made of synthetic resin panels or metal panels, or may be formed into a single box shape from synthetic resin material or metal material.

[0011] A front door 12 is attached to the front side of the housing so as to be able to open and close. That is, the housing has three support shafts, one above the other, on the left side when viewed from the front, and front door 12 has bearings 14a, 14b, and 14c at positions corresponding to the support shafts. The front door 12 is supported on the housing so as to be rotatable about an opening / closing axis that extends in the vertical direction and connects the support shafts, and the open front side of the housing can be opened and closed by rotating the front door 12.

[0012] Furthermore, a locking device 15 is provided on the rear surface of the front door 12 on the opposite side of the opening / closing axis (the left side in FIG. 1), and a lock receiving portion is provided on the housing at a position corresponding to the locking device 15. This locking device 15 locks the front door 12, which is closed relative to the housing, so that it cannot be opened. A key cylinder integrated with the locking device 15 is provided on the front right end of the front door 12, and the locking device 15 is configured to be switched between a locked state and an unlocked state by operating a predetermined key on the key cylinder. That is, by operating the key cylinder 17, the locking device 15 is engaged with the lock receiving portion to set the front door 12 in a locked state, making it impossible to open the front door 12, and the engagement between the locking device 15 and the lock receiving portion is released to set the front door 12 in an unlocked state, so that the front door 12 can be opened.

[0013] A game panel 20 for displaying information about games is provided in the center of the front of the front door 12. The game panel 20 is made of a transparent synthetic resin material, and the interior of the slot machine 10 can be seen through the game panel 20. A reel unit, which is a reel-type display device (not shown), is attached to the back side of the front door 12 corresponding to the game panel 20. The operation of the reel unit is controlled by the main control device via the main relay board 71.

[0014] The reel unit includes a left reel, a center reel, and a right reel, each formed in a cylindrical (annular) shape. Each reel is rotatably supported so that its central axis is the axis of rotation of that reel. The axes of rotation of each reel are arranged on the same axis extending substantially horizontally, and a portion of the surface of each reel is visible through the game panel 20. Furthermore, when each reel rotates forward, the surface of each reel is seen through the game panel 20 as if it were moving from top to bottom.

[0015] The front door 12 is provided with a medal insertion section 24 (see FIG. 3) for inserting medals. Medals inserted through the medal insertion section 24 are guided to either an intake passage 26 or a discharge passage 27 by a selector 25 provided on the back surface of the front door 12. The medals guided to the intake passage 26 are then guided to a hopper device housed inside the housing. Meanwhile, medals guided to the discharge passage 27 are guided from a medal discharge port provided on the lower front surface of the front door 12 to a medal tray 29 (see FIG. 3) and are returned to the player. The hopper device is composed of a storage tank for storing medals and a payout device for paying out medals to the player. The payout device rotates a medal payout rotary plate to discharge medals into an opening 27a provided in the discharge passage 27, and then pays out the medals to the medal tray via the discharge passage 27. As described above, the selector 25, the intake passage 26 and the discharge passage 27 provided on the front door 12 are unitized as a dispensing unit 28.

[0016] An upper lamp 51 and a pair of left and right speaker grills are provided at the upper front side of the front door 12 of the slot machine 10, and side lamps are provided on the left and right sides. The upper lamp 51 and side lamps light up and flash as the game progresses, creating effects. In addition, a liquid crystal display device 55 that provides various information to the player is provided on the upper back side of the gaming panel 20. The liquid crystal display device 55 is used to execute various display effects as the game progresses and to notify the player of the status when the power is turned on or when an error occurs, and is configured with a liquid crystal display that displays images.

[0017] 1, a pair of upper speakers (left and right) are provided at the top on the back side of the front door 12, and a pair of lower speakers 58 (left and right) are provided at the bottom. The upper speakers generate various sound effects as the game progresses, and these sound effects are emitted through a speaker grill to the front side of the front door 12. The lower speaker 58 generates notification sounds that notify the player of the game status, and these notification sounds are emitted through a speaker grill 54 to the front side of the front door 12.

[0018] The upper lamp 51, side lamps, LCD display 55, upper speaker, and lower speaker 58 are controlled by a sub-controller. The sub-controller is attached to the inner surface of the cabinet via a main body base. Furthermore, a main controller is attached to the main body base, which controls the reel unit and hopper device to comprehensively manage the game. A power supply box is also provided inside the cabinet. The power supply box houses a power supply unit and is equipped with a power switch for supplying power to each part, including the sub-controller and main controller.

[0019] As shown in Fig. 1, a main relay board 71 and a sub-relay board 72 are provided on the back side of the front door 12. The main relay board 71 relays power supplied from the power supply box via the main control device and control signals transmitted from the main control device to various components such as the reel unit. The sub-relay board 72 relays power supplied from the power supply box via the sub-control device and control signals transmitted from the sub-control device to various components such as the effect buttons, LCD display device 55, upper lamp 51, side lamp, upper speaker, and lower speaker 58. The main relay board 71 and the sub-relay board 72 are each provided with an input connector for connecting wiring (not shown) from the main control device and the sub-control device, and a distribution connector for connecting distribution wiring (not shown) connected to various components.

[0020] [Lower unit structure] The structure of the lower unit 12a of the front door 12 will be described below with reference to Figures 2 to 4. Figure 2 is a rear view of the lower unit 12a of the front door 12 of the slot machine 10. Figure 3 is a vertical cross-sectional view of the lower unit 12a, and a cross-sectional view taken along the line AA in Figure 2. Figure 4 is an exploded perspective view of the lower unit 12a as seen from the rear side.

[0021] 2 to 4, in rear view, lower unit 12a of front door 12 has payout unit 28 provided from the upper left side to the lower center, main relay board 71 and sub-relay board 72 provided vertically side by side in the center right side, and a pair of lower speakers 58 provided on both sides of the lower part. A medal insertion port 24 is provided in operation console 12b on the front side of lower unit 12a, and the lower end of medal insertion port 24 is connected to selector 25 of payout unit 28.

[0022] As shown in FIG. 4, the payout unit 28 has a base member 28A, which supports the selector 25, the intake passage 26, and the discharge passage 27. The payout unit 28 is detachably attached to the lower unit 12a from the rear side of the front door 12. The medal insertion unit 24 is attached by inserting it vertically into the operation console 12b, and this medal insertion unit 24 is also detachable. Therefore, if the slot machine 10 is made medalless, the payout unit 28 and the medal insertion unit 24 can be removed from the lower unit 12a and used.

[0023] [Lower speaker structure] The configuration of the lower speaker 58 will be described below with reference to Figs. 5 to 8. Fig. 5 is an exploded perspective view of the lower unit 12a as seen from the rear side. Fig. 6 is an enlarged vertical cross-sectional view of a portion of the lower unit 12a. Fig. 7 is a perspective view of the rear cover of the speaker. Fig. 8 is a front view of the rear cover of the speaker.

[0024] As shown in Figures 5 and 6, a speaker grill 54 and a lower speaker 58 are provided on the main body of the lower unit 12a of the front door 12, and a rear cover 60 is provided on the rear side of the lower speaker 58. The speaker grill 54 has multiple through-holes that communicate between the outside and the interior of the front door 12. The lower speaker 58 is a dynamic speaker including a frame 58A, a diaphragm 58B, an edge 58C, an electromagnetic coil 58D, a plate 58E, a magnet 58F, and a yoke 58G. The rear cover 60 includes a base 61 fixed to the inner surface of the lower unit 12a, a cylindrical portion 62 extending from the base 61 toward the inside of the housing, and an extension cylindrical portion 63 extending from the cylindrical portion 62 toward the inside of the housing to surround the rear end of the lower speaker 58. The cylindrical portion 62 is provided with a plurality of openings 64 that are aligned in the circumferential direction and open to the inside of the main body of the lower unit 12a.

[0025] As shown in FIGS. 7 and 8 , the cylindrical portion 62 of the rear cover 60 has first wall portions 62A and second wall portions 62B alternately arranged in the circumferential direction, and a communication passage 65 is provided between the first wall portions 62A and the second wall portions 62B. The communication passage 65 is a space that connects an outer opening 64 thereof with the interior space of the rear cover 60 and is formed in a crank shape bent at least twice. In a cross-sectional view, the first wall portion 62A has a first radial wall 62C extending in the radial direction and a first circumferential wall 62D extending in the circumferential direction and intersecting an intermediate portion of the first radial wall 62C, forming a cross-shaped cross section. The second wall portion 62B has a second radial wall 62E extending in the radial direction, a second outer peripheral wall 62F extending in the circumferential direction and intersecting the outer circumferential side of the second radial wall 62E, and a second inner circumferential wall 62G extending in the circumferential direction and intersecting the inner circumferential side of the second radial wall 62E, forming an I-shaped cross section.

[0026] An opening 64 is formed by a gap between the first radial wall 62C of the first wall portion 62A and the second outer peripheral wall 62F of the second wall portion 62B. The first peripheral wall 62D of the first wall portion 62A radially overlaps the second inner peripheral wall 62G of the second wall portion 62B and also radially overlaps the second outer peripheral wall 62F. The communicating passage 65 is formed by, in order from the inside of the rear cover 60, the gap between the first radial wall 62C and the second inner peripheral wall 62G, the gap between the first peripheral wall 62D and the second inner peripheral wall 62G, the gap between the first peripheral wall 62D and the second radial wall 62E, the gap between the first peripheral wall 62D and the second outer peripheral wall 62F, and the gap between the first radial wall 62C and the second outer peripheral wall 62F, and continues to the opening 64. Therefore, the communicating passage 65 is formed in a crank shape that bends four times from the internal space of the rear cover 60 to the opening 64.

[0027] As shown in FIG. 6 , the cylindrical portion 62 is provided to surround the outer periphery of the frame 58A of the lower speaker 58. The extension cylindrical portion 63 is formed to include a small-diameter cylindrical portion 63A whose outer diameter is smaller than that of the cylindrical portion 62, and a flange portion 63B that bends radially inward from the rear end of the small-diameter cylindrical portion 63A and fits along the rear end of the lower speaker 58. The small-diameter cylindrical portion 63A is provided to surround the outer periphery of the plate 58E and magnet 58F of the lower speaker 58, and the flange portion 63B is provided with no gap between them and the magnet 58F and yoke 58G. A plurality of slits 63C are provided from the small-diameter cylindrical portion 63A to the flange portion 63B. The width of these slits 63C is very small so that wires or the like cannot pass through them.

[0028] In the above-described lower speaker 58, even if a wire or the like inserted through a through-hole in speaker grill 54 penetrates diaphragm 58B and edge 58C and the tip of the wire or the like reaches the inner surface of cylindrical portion 62 of rear cover 60 and enters the gap between first radial wall 62C and second inner circumferential wall 62G, which is the entrance of communicating passage 65, the wire or the like is prevented from entering further because communicating passage 65 is formed in a crank shape bent four times. Therefore, a wire or the like inserted from the outside cannot pass through opening 64 in rear cover 60 and reach the internal space of front door 12, preventing unauthorized access to internal devices of the housing.

[0029] According to this embodiment, the following actions and effects can be achieved. (1) The rear cover 60 covering the rear side of the lower speaker 58 has a connecting passage 65 formed in a crank shape with at least two bends, so that even if someone tries to illegally access the inside of the housing through the lower speaker 58 using a wire or the like, the wire or the like cannot pass through the connecting passage 65, thereby preventing such illegal acts. Furthermore, the multiple openings 64 and connecting passages 65 in the rear cover 60 communicate the internal space of the rear cover 60, which is the space behind the lower speaker 58, with the internal space of the front door 12, so that the sound quality and sound pressure of the lower speaker 58 can be properly ensured.

[0030] (2) The cylindrical portion 62 of the rear cover 60 has a first wall portion 62A and a second wall portion 62B, and a communication passage 65 is provided between the first wall portion 62A and the second wall portion 62B. The first peripheral wall 62D of the first wall portion 62A and the second inner peripheral wall 62G of the second wall portion 62B are arranged to overlap radially. As a result, the communication passage 65 is formed in a crank shape that is bent four times, which makes it possible to more reliably prevent fraudulent acts.

[0031] (3) The extension tube portion 63 of the rear cover 60 has a small diameter tube portion 63A and a flange portion 63B, and the flange portion 63B is provided along the rear end portion of the lower speaker 58, thereby eliminating the gap between the rear cover 60 and the lower speaker 58, and more reliably preventing fraudulent acts.

[0032] [Modification of the embodiment] The present invention is not limited to the above-described embodiment, and any modifications and improvements that can achieve the object of the present invention are included in the present invention. (1) In the above embodiment, a structure in which a rear cover 60 is provided on the rear side of the lower speaker 60 and this rear cover 60 prevents unauthorized access to the inside of the housing is exemplified, but a similar structure may be adopted not only for the lower speaker 58 but also for the upper speaker. Also, a similar structure may be applied not only to speakers but also to parts in various performance means where there is a possibility that the outside and the inside of the housing may communicate with each other.

[0033] (2) In the back cover 60 of the above embodiment, the cylindrical portion 62 has the first wall portion 62A and the second wall portion 62B, and the communication passage 65 is provided between the first wall portion 62A and the second wall portion 62B, but this configuration is not limited to this. In other words, the cylindrical portion is not limited to having the first wall portion 62A with a cross-shaped cross section and the second wall portion 62B with an I-shaped cross section, and can be configured by combining wall portions of any suitable shape as long as the communication passage is formed in a crank shape two or more times.

[0034] Second Embodiment A second embodiment of the present invention will be described below with reference to Figures 9 to 21. Figure 9 is a rear view of the front door of a slot machine 10, Figure 10 is a front view of an upper unit 12a of the front door 12 of the slot machine, and Figure 11 is a vertical cross-sectional view of the upper unit 12a. Components having the same functions as those in the above embodiment will be described using the same reference numerals, and components having the same reference numerals but different functions will be treated as unique reference numerals in this embodiment.

[0035] As shown in Fig. 9, a main relay board 71 and a sub relay board 72 are provided on the back side of the front door 12. As shown in Figs. 10 and 11, on the front side of the upper unit 12a, an upper lamp 51 and a pair of left and right speaker grills 52 are provided at the top, and a side lamp 53 as a light-emitting means is provided on the left side.

[0036] [Side lamp structure] The structure of the side lamp 53 will be described below with reference to Figs. 12 to 19. Fig. 12 is an exploded perspective view of the side lamp 53 provided on the front door 12. Fig. 13 is an exploded perspective view of a side lamp 60 of the side lamp 53. Fig. 14 is a front view of the side lamp 60. Fig. 15 is a cross-sectional view of the side lamp 60, taken along the line AA in Fig. 14. Fig. 16 is a cross-sectional view of the side lamp 60, enlarging a portion of Fig. 15.

[0037] As shown in Fig. 12, the side lamp 53 is made up of a side lamp 60 and a display unit 70. As shown in Figs. 13 to 15, the side lamp 60 includes a base member 61 fixed to the metal frame of the upper unit 12a of the front door 12, a side cover 62 provided on the side of the base member 61, a substrate 63 provided inside the base member 61, a light guide plate 64 provided on the front side of the substrate 63 inside the base member 61, and a translucent cover 65 provided to cover the front and sides of the light guide plate 64.

[0038] The base member 61 is an integrally molded resin product and has a main plate portion 61A extending in the front-rear direction, a sub-plate portion 61B extending inward in the left-right direction from the main plate portion 61A, and a board support portion 61C protruding laterally from the rear of the main plate portion 61A and supporting the board 63. The side cover 62 is an opaque integrally molded resin product and is attached to cover the outer surface on the rear side of the base member 61 and forms the side surface of the upper unit 12a of the front door 12.

[0039] The substrate 63 is a rigid substrate such as a paper phenolic substrate, a paper epoxy substrate, or a glass composite substrate, and has a circuit formed on its surface. The substrate 63 is electrically connected to the sub-relay substrate 72 by wiring and a connector (not shown). A plurality of light sources 63A are mounted on the front surface of the substrate 63. The light sources 63A are composed of light-emitting diodes (LEDs) and emit light forward. The substrate 63 is supported by a substrate support portion 61C of the base member 61, and extends up and down along a plane perpendicular to the left-right and vertical directions, i.e., the front-rear direction of the slot machine 10.

[0040] The light-transmitting cover 65 is a one-piece molded product made of a transparent or translucent resin material, and transmits light diffused and emitted by the light guide plate 64 to the outside. The light-transmitting cover 65 is formed in a convex shape extending outward from the front side to the side side of the slot machine 10, and is provided to cover the front and sides of the light guide plate 64. One outer rear end of the light-transmitting cover 65 is engaged with the side cover 62, and an inner end is engaged and attached to the tip of the main plate portion 61A of the base member 61. The light-transmitting cover 65 is provided with a pattern that appears when light passes through it.

[0041] As shown in FIG. 16 , the light guide plate 64 is a one-piece molded product made of a transparent resin material, and is vertically long with a front-to-rear dimension that conforms to the shape of the light-transmitting cover 65. The light guide plate 64 is L-shaped in cross section and includes a first plate portion 64A extending in the front-to-rear direction (first direction) and a second plate portion 64B bending from the front end of the first plate portion 64A and extending in the left-to-right direction (second direction). The outer sides of the bending portions of the first plate portion 64A and the second plate portion 64B are chamfered, and this chamfering forms a reflecting portion 64C that reflects light guided to the first plate portion 64A to the second plate portion 64B. The rear end surface of the first plate portion 64A faces the substrate 63 and serves as an incident surface 64D onto which light from the light source 63A is incident.

[0042] A first diffusion section 64E is formed on the inner surface of the first plate section 64A of the light guide plate 64, which diffuses and emits light guided to the first plate section 64A toward the side of the translucent cover 65. This first diffusion section 64E is formed by cutting the inner surface of the first plate section 64A into an uneven shape with a random pattern, so that uniform light is emitted toward the side of the translucent cover 65. A second diffusion section (diffusion section) 64F is formed on the inner surface of the second plate section 64B, which diffuses and emits light guided from the reflecting section 64C to the second plate section 64B toward the forward translucent cover 65. The second diffusion section 64F is formed in a stepped shape from the reflecting section 64C toward the tip side of the second plate section 64B, and the second plate section 64B is formed so that its plate thickness gradually decreases toward the tip side. The second diffusion portion 64F is formed in a continuous band shape and uneven shape along the up-down direction (the direction orthogonal to the second direction) in a plan view of the second plate portion 64B.

[0043] In the above-described side lamp 60, light emitted from the light source 63A of the substrate 63 is introduced into the first plate portion 64A from the incident surface 64D and travels forward (first direction) as shown by the arrow in Fig. 18, while a portion of the light is diffused by the first diffusing portion 64E and emitted to the side of the first plate portion 64A, and the emitted light shines while passing through the translucent cover 65. Furthermore, the light that reaches the tip of the first plate portion 64A is reflected by the reflecting portion 64C and travels inward in the left-right direction (second direction) within the second plate portion 64B, and is sequentially diffused by the second diffusing portion 64F of the second plate portion 64B, which has a gradually thinner plate thickness, and is emitted forward of the second diffusing portion 64F, and the emitted light shines while passing through the translucent cover 65.

[0044] Fig. 17 is a front view of the side lamp 53. Fig. 18 is a cross-sectional view of the side lamp 53, taken along the line BB in Fig. 17. Fig. 19 is a cross-sectional view of a display unit 70 of the side lamp 53, enlarging a portion of Fig. 18. The display unit 70 includes a substrate 71 and a reflector (reflecting plate) 72 supported by a base member 61 of the side lamp 60, a light-transmitting cover (cover) 73 that covers the front of the substrate 71 and the reflector 72, a decorative sheet 74 that is provided in close contact with the inner surface of the light-transmitting cover 73, and an exterior member 75 that holds the light-transmitting cover 73 and the decorative sheet 74 against the base member 61.

[0045] The substrate 71 is a rigid substrate such as a paper phenolic substrate, a paper epoxy substrate, or a glass composite substrate. A circuit is provided on its surface and electrically connected to the sub-relay substrate 72 via wiring and connectors (not shown). A plurality of light sources 71A are mounted on the front surface of the substrate 71. The light sources 71A are side-view LEDs (light-emitting diodes) that emit strong light toward the sides and weak light toward the front. Specifically, the light sources 71A include a first light source that emits high-intensity light along the substrate 71 and a second light source that emits low-intensity light toward the front of the substrate 71. The substrate 71 is supported by the sub-plate 61B of the base member 61, and extends vertically and left-right along a plane perpendicular to the front-to-rear direction of the slot machine 10.

[0046] The reflector 72 is an integrally molded resin part made of a highly reflective material, such as white. It has a base portion 72A that extends in both the left-right and vertical directions and a reflective surface portion 72B that extends forward from the base portion 72A. A tapered inclined surface 72C is formed on the inside of the intersection between the base portion 72A and the reflective surface portion 72B. The translucent cover 73 is an integrally molded part made of a transparent resin material. The decorative sheet 74 is a translucent resin sheet printed with a design or the like. The decorative sheet 74 and the translucent cover 73 transmit light emitted from the light source 71A of the board 71 to the outside. The translucent cover 73 is formed in a convex, curved shape extending from the side of the slot machine 10 toward the inside and rearward.

[0047] The exterior member 75 is an integrally molded resin product and is formed with an opening 75A through which light that has passed through the decorative sheet 74 and the light-transmitting cover 73 passes. The exterior member 75 has its front end engaged with the main plate portion 61A of the base member 61 and its rear end engaged with the sub-plate portion 61B of the base member 61, thereby allowing the exterior member 75 to be attached while holding the light-transmitting cover 73 and the decorative sheet 74. The light-transmitting cover 73 and the substrate 71 held in this manner are arranged non-parallel to each other; that is, the distance to the light-transmitting cover 73 is large on the outer side of the substrate 71 in the left-right direction (the left side in FIG. 19, one end side of the substrate 71), and the distance to the light-transmitting cover 73 is small on the inner side of the substrate 71 in the left-right direction (the right side in FIG. 19, the other end side of the substrate 71).

[0048] In the display unit 70 described above, high-brightness light emitted from the light source 71A (first light source) of the substrate 71 along the substrate 71 travels toward the inclined surface 72C and reflective surface portion 72B of the reflector 72, and is reflected therefrom toward the decorative sheet 74 and the translucent cover 73, which are a large distance ahead. The light traveling toward the decorative sheet 74 and the translucent cover 73 in this manner is reflected by the inclined surface 72C and reflective surface portion 72B, and is moderately diffused while decreasing in brightness. Meanwhile, low-brightness light emitted forward from the light source 71A (second light source) of the substrate 71 travels toward the decorative sheet 74 and the translucent cover 73, which are a small distance ahead. This light shines as it passes through the decorative sheet 74, and then passes through the translucent cover 65.

[0049] According to this embodiment, the following actions and effects can be achieved. (1) The light guide plate 64 of the side lamp 60 has a first plate portion 64A, a second plate portion 64B, and a reflecting portion 64C, and the second plate portion 64B is formed so that its thickness gradually decreases toward its tip end and includes a second diffusing portion 64F that diffuses light guided to the second plate portion 64B, thereby making it possible to uniformize the amount of light emitted from each portion of the second plate portion 64B and to emit light from the surface. In this way, uniform surface emission can be obtained from the second plate portion 64B, which is separated from the light source 63A and intersects with the direction of irradiation of light from the light source 63A, so there is no need to prepare another light source corresponding to the second plate portion 64B, and the structure of the side lamp 60 can be simplified.

[0050] (2) Furthermore, the side lamp 60 can make the amount of light emitted from the second plate portion 64B more uniform by gradually diffusing light using the second diffusion portion 64F formed in a stepped pattern toward the tip side of the second plate portion 64B of the light guide plate 64. Furthermore, the second diffusion portion 64F is formed in a continuous band-like, uneven shape along the up-down direction in a plan view of the second plate portion 64B, thereby making it possible to uniformly diffuse light within the second plate portion 64B.

[0051] (3) In the display unit 70, the light source 71A emits high-luminance light along the substrate 71 toward one end where the distance between the substrate 71 and the translucent cover 73 is large, and this light is reflected and spread by the inclined surface 72C and the reflective surface 72B of the reflector 72, and the light source 71A emits low-luminance light forward at the other end where the distance between the substrate 71 and the translucent cover 73 is small, thereby making it possible to equalize the light that reaches the translucent cover 73. Therefore, even if the substrate 71 and the translucent cover 73 are not arranged parallel to each other, the light that passes through the translucent cover 73 can be made uniform. This allows for a simplified structure of the display unit 70 while increasing the degree of freedom in the arrangement of the substrate 71 and the display unit 70 and improving the design of the display unit 70.

[0052] (4) The light source 71A of the substrate 71 is composed of a side-view LED, and has a first light source that emits high-brightness light along the substrate 71 and a second light source that emits low-brightness light toward the front of the substrate 71, thereby simplifying the structure of the substrate 71 and the light source 71A.

[0053] [Modification of the second embodiment] The present invention is not limited to the above-described embodiment, and any modifications and improvements that can achieve the object of the present invention are included in the present invention. (1) In the above embodiment, the side lamps 60 and the display unit 70 of the side lamps 53 are exemplified as light-emitting means, but the present invention is not limited to the side lamps 53 and can be applied to light-emitting units of various parts of the gaming machine, such as the upper lamps and lower lamps.

[0054] (2) In the side lamp 60 of the above embodiment, the light guide plate 64 has an L-shape in cross section and includes a first plate portion 64A extending in the front-rear direction and a second plate portion 64B bending from the front end of the first plate portion 64A and extending in the left-right direction. However, this is not limited thereto, and the light guide plate 64 may be formed in a flat plate shape. When the light guide plate 64 is formed in a flat plate shape, a configuration corresponding to the second diffusion portion 64F of the second plate portion 64B may be provided at the end opposite to the incident surface 64D through which light enters the light guide plate 64.

[0055] (3) In the side lamp 60 of the above embodiment, the second plate portion 64B of the light guide plate 64 gradually becomes thinner toward the tip end, and the second diffusion portion 64F is formed in a stepped shape. However, this is not limited to this, and the configurations shown in FIGS. 20(A) and 20(B) may also be used. In the light guide plate 64 shown in FIG. 20(A), the second plate portion 64B gradually becomes thinner toward the tip end, and the second diffusion portion 64F consisting of a plurality of recesses (dimples) is provided on the flat inner surface. In the light guide plate 64 shown in FIG. 20(B), the second diffusion portion 64F is formed in a continuous band-like, wavy shape along the vertical direction in a plan view of the second plate portion 64B.

[0056] (4) In the display unit 70 of the embodiment, the light source 71A of the substrate 71 is configured as a side-view LED. However, as shown in Fig. 21 , a first light source 71B and a second light source 71C may be used, each of which has different luminance and emits light forward. The first light source 71B is disposed on one end side (outer side in the left-right direction) of the substrate 71, and emits high-luminance light forward from the substrate 71, causing the light to reach the translucent cover 73 that is located a large distance from the substrate 71. On the other hand, the second light source 71C is disposed on the other end side (inner side in the left-right direction) of the substrate 71, and emits low-luminance light forward from the substrate 71, causing the light to reach the translucent cover 73 that is located a small distance from the substrate 71.

[0057] Third Embodiment A third embodiment of the present invention will be described below with reference to Figures 22 to 31. Figure 22 is a rear view of the front door of slot machine 10, Figure 23 is a front view of upper unit 12a of front door 12 of the slot machine, and Figure 24 is a vertical cross-sectional view of upper unit 12a and a cross-sectional view taken along the line AA in Figure 23. Components having the same functions as those in the above embodiments will be described using the same reference numerals, and components having the same reference numerals but different functions will be treated as unique reference numerals in this embodiment.

[0058] 23 and 24, an upper lamp 51 and a pair of left and right speaker grills 52 are provided at the top of the front side of the upper unit 12a, and a side lamp 53 serving as a light-emitting means is provided on the left side. As shown in Fig. 22, a main relay board 31 and a sub relay board 32 are provided on the back side of the front door 12.

[0059] [Upper lamp structure] The structure of the upper lamp 51 will be described below with reference to Figures 25 to 29. Figure 25 is a vertical cross-sectional view of the upper unit 12a of the front door 12 as seen from the rear side, and is a cross-sectional view taken along arrow C in Figure 24. Figure 26 is a horizontal cross-sectional view of the upper unit 12a as seen from above, and is a cross-sectional view taken along arrow BB in Figures 23 to 25. Figure 27 is a top view of the upper unit main body (door main body). Figure 28 is a bottom view of the detachable unit 70 of the upper lamp 51. Figure 29 is an exploded perspective view of the upper lamp 51.

[0060] As shown in Figures 25 to 29, the upper lamp 51 serving as a performance device is configured to include a fixed performance section 60 fixed to the upper unit 12a body (door body) and a detachable unit 70 detachably attached to the upper unit 12a body. As shown in Figures 27 and 29, the fixed performance section 60 is configured to include a base member 61 to which the speaker grill 52 is attached, a substrate 62 fixed to the front side of the base member 61, a first fixed plate 63 fixed to the upper unit 12a body, a second fixed plate 64 fixed to the upper side of the first fixed plate 63, and a movable plate 65 provided below the first fixed plate 63. The first fixed plate 63, the second fixed plate 64, and the movable plate 65 form a fixed section on the door body 12 side for fixing the detachable unit 70. The fixed performance section 60 is arranged so as not to protrude upward from the top surface of the upper unit 12a body.

[0061] As shown in FIGS. 28 and 29 , the detachable unit 70 includes a detachable base 71 on the rear side, a light-transmitting cover 72 attached to the front side of the detachable base 71, a reflector 73 and a light guide plate 74 (described later) provided between the detachable base 71 and the light-transmitting cover 72, and three pins 75 serving as engagement portions fixed to the bottom surface of the detachable base 71. As shown in FIGS. 22 to 25 , the detachable unit 70 is provided so as to protrude above the top surface of the upper unit 12a main body. By removing the detachable unit 70 from the upper unit 12a main body, the slot machine 10 can be stored in the same height as a general gaming machine, and when transporting the slot machine 10, removing the detachable unit 70 from the front door 12 allows the slot machine 10 to be transported using a general-purpose transport case or the like.

[0062] The first fixed plate 63 of the fixed performance unit 60 has a horizontal surface portion 63A and a vertical surface portion 63B extending downward from the front edge of the horizontal surface portion 63A, forming an L-shaped cross section. The second fixed plate 64 has a horizontal surface portion 64A. The horizontal surfaces 63A, 64A of the first fixed plate 63 and the second fixed plate 64 are fixed to the fixed portion 12b of the upper unit 12a body with multiple screws. A base member 61 is fixed to the vertical surface portion 63B of the first fixed plate 63, thereby fixing the speaker grill 52 and the circuit board 62 to the upper unit 12a body. The movable plate 65 has two elongated holes 65A. Locking pins 65B inserted through the elongated holes 65A are fixed to the first fixed plate 63 and the second fixed plate 64, so that the movable plate 65 is supported slidably in the left-right direction along the underside of the first fixed plate 63. Furthermore, the movable plate 65 is biased to the left side when viewed from the front of the upper unit 12a by a spring 66 connected between the movable plate 65 and the first fixed plate 63.

[0063] The first fixed plate 63 and the second fixed plate 64 are each provided with through-holes 63C, 64C through which pins 75 are inserted for positioning. Three elongated holes 65C are formed in the movable plate 65, through which the pins 75 are inserted and engaged. When biased by a spring 66, the edges of the elongated holes 65C engage with the pins 75, thereby engaging the detachable unit 70 with the fixed performance unit 60. A release lever 67 is fixed to the rear side of the movable plate 65 as a release operation unit for disengaging the detachable unit 70. By sliding the release lever 67 to the left in FIG. 25, the engagement between the pins 75 and the elongated holes 65C is released, allowing the detachable unit 70 to be removed from the fixed performance unit 60. The release lever 67 is provided on the rear side of the front door 12 and can be operated when the front door 12 is open relative to the housing.

[0064] Two extension pieces 71A and two fitting portions 71B are provided on the bottom surface of the detachable base 71 of the detachable unit 70. The extension piece 71A is formed with an inclined surface on its lower end side. Two insertion holes 63D, 64D are formed in the first fixed plate 63 and the second fixed plate 64, respectively, through which the extension piece 71A passes, and two abutment portions 65D are formed in the movable plate 65 that can abut against the inclined surface of the extension piece 71A. When the movable plate 65 is slid by the release lever 67, these two abutment portions 65D abut against the inclined surface of the extension piece 71A, thereby pushing the detachable unit 70 upward and making it easier to remove the detachable unit 70.

[0065] The first fixed plate 63 and the second fixed plate 64 have cutouts 63E, 64E formed in them, into which the fitting portion 71B fits, and fitting the fitting portion 71B into these cutouts 63E, 64E stabilizes the attached state of the detachable unit 70. In addition, a mark 65E is provided on the movable plate 65, and a transparent portion 71C penetrating the bottom surface is provided on the bottom surface of the detachable base 71, and when the movable plate 65 is slid to a position where the elongated hole 65C and the pin 75 engage, the mark 65E can be seen from the transparent portion 71C, allowing the engagement state of the detachable unit 70 to be confirmed.

[0066] [Upper lamp light emitting structure] The light-emitting structure of the upper lamp 51 will be described below with reference to Figures 30 and 31. Figure 30 is a front view of the fixed performance unit 60 of the upper lamp 51. Figure 31 is an enlarged longitudinal cross-sectional view of a portion of the upper lamp 51. A first light source 62A and a second light source 62B are mounted on the substrate 62 of the fixed performance unit 60 as multiple light sources. The first light source 62A is provided below approximately the middle of the substrate 62 in the height direction, and these first light sources 62A are composed of light-emitting diodes (LEDs) that emit light mainly forward. The second light sources 62B are provided along the upper edge of the substrate 62, and these second light sources 62B are composed of side-view LEDs that emit light mainly upward. In addition, a protective cover 62C that covers the front surface of the substrate 62 can be attached to the fixed performance unit 60.

[0067] A reflector 73 and a light guide plate 74 are provided inside the detachable unit 70. The reflector 73 is supported by the detachable base 71 and is provided in a vertical state. The light guide plate 74 has a first light guide portion (first plate portion) 74A that covers the front of the substrate 62 and a second light guide portion (first plate portion) 74B that covers the front of the reflector 73, and is formed with a crank-shaped cross section, with the lower end surface of the second light guide portion 74B being located above the second light source 62B. A light-transmitting cover 72 is provided to cover the front of the light guide plate 74.

[0068] In the above-described upper lamp 51, light emitted from the first light source 62A on the substrate 62 is introduced into the first light guiding portion 74A of the light guiding plate 74, diffused appropriately, and emitted forward from the first light guiding portion 74A, where the emitted light shines while passing through the light-transmitting cover 72. Furthermore, light emitted upward from the second light source 62B on the substrate 62 enters the lower end surface of the second light guiding portion 74B, is diffused by the second light guiding portion 74B, and is reflected by the reflector 73, where it is emitted forward from the second light guiding portion 74B, where the emitted light shines while passing through the light-transmitting cover 72.

[0069] According to this embodiment, the following actions and effects can be achieved. (1) The upper lamp 51 has a fixed effect unit 60 fixed to the upper unit 12a of the front door 12 and a detachable unit 70 detachably attached to the fixed effect unit 60. The fixed effect unit 60 does not protrude upward from the top surface of the upper unit 12a, and the detachable unit 70 protrudes upward from the top surface of the upper unit 12a. By removing the detachable unit 70, the front door 12 can be resized to a height equivalent to that of a typical gaming machine. Therefore, when transporting the slot machine 10, the detachable unit 70 can be removed from the front door 12, allowing for the use of a general-purpose transport case or the like. After transporting the slot machine 10 to a predetermined location, the detachable unit 70 can be attached to the front door 12, easily completing assembly of the slot machine 10. Furthermore, the fixed effect unit 60 of the upper lamp 51 is fixed to the front door 12 as a common specification, while the detachable unit 70 can be replaced relatively easily, allowing for a variety of effect variations.

[0070] (2) Furthermore, the upper lamp 51 prevents the detachable unit 70 from being removed from the front door 12 unless the release lever 67 is operated with the front door 12 open, thereby preventing the detachable unit 70 from being removed improperly.

[0071] (3) The fixed performance section 60 has first and second fixed plates 63, 64, a movable plate 65, and a spring 66, and the elongated hole 65C of the movable plate 65 engages with the pin 75 of the detachable unit 70, thereby engaging the detachable unit 70 with the fixed performance section 60, and the engagement between the elongated hole 65C and the pin 75 is released by operating the release lever 67 to slide the movable plate 65, thereby enabling smooth attachment and detachment of the detachable unit 70. In addition, the movable plate 65 is biased by the spring 66 to maintain the engagement between the elongated hole 65C and the pin 75, so the engagement is not unexpectedly released and the attached state of the detachable unit 70 can be maintained.

[0072] (4) When the movable plate 65 slides to a position where the elongated hole 65C and the pin 75 engage, the mark 65E on the movable plate 65 becomes visible through the transparent portion 71C of the detachable unit 70, allowing the engagement state of the detachable unit 70 to be confirmed. On the other hand, if the mark 65E cannot be seen through the transparent portion 71C, it can be confirmed that the elongated hole 65C and the pin 75 are not fully engaged, preventing the detachable unit 70 from being incompletely attached. Furthermore, the fitting portion 71B provided on the detachable unit 70 fits into the cutout portions 63E, 64E of the fixed performance portion 60, thereby stabilizing the attachment state of the detachable unit 70.

[0073] (5) In the upper lamp 51, the fixed performance part 60 has a substrate 62, and the detachable unit 70 has a light guide plate 74 and a translucent cover 72, so that light from the light sources 62A, 62B of the substrate 62 is guided to the detachable unit 70 by the light guide plate 74, and the light diffused by the light guide plate 74 is emitted to the translucent cover 72, thereby realizing a light-emitting performance. Therefore, there is no need to place a substrate on the detachable unit 70, and work such as connecting wiring is not required when attaching the detachable unit 70 to the front door 12, which further simplifies the installation work of the detachable unit 70.

[0074] (6) The fixed performance unit 60 is capable of attaching a protective cover 62C that covers the front of the board 62, so that when transporting the slot machine 10 with the detachable unit 70 removed from the front door 12, the protective cover 62C can be attached to protect the board 62.

[0075] (7) In the upper lamp 51, the light source of the substrate 62 has a first light source 62A and a second light source 62B, and the light guide plate 74 of the detachable unit 70 has a first light guiding portion (first plate portion) 74A and a second light guiding portion (first plate portion) 74B, the first light guiding portion 74A is located in front of the first light source 62A, and one end face of the second light guiding portion 74B faces the second light source 62B and extends in a direction away from the substrate 62, so that light from the first light source 62A can be diffused forward by the first light guiding portion 74A, and light from the second light source 62B can be guided by the second light guiding portion 74B to a position away from the substrate 62 and diffused therein.

[0076] [Modification of the third embodiment] The present invention is not limited to the above-described embodiment, and any modifications and improvements that can achieve the object of the present invention are included in the present invention. (1) In the above embodiment, the upper lamp 51 is exemplified as the effect means, but the present invention is not limited to the upper lamp 51 and can be applied to light-emitting effect parts of each part of the gaming machine, such as the side lamp 53 and the lower lamp. In addition, the effect means is not limited to those that perform light-emitting effect, but may also be a movable effect part or a display effect part.

[0077] (2) In the upper lamp 51 of the above embodiment, the detachable unit 70 is attached to the fixed performance part 60 from above, and the movable plate 65 slides left and right to engage with the pin 75, but this configuration is not limited to this. That is, the detachable unit 70 may be attached to the fixed performance part 60 from the front to the rear, or may be attached by moving in the left and right direction. Furthermore, the sliding direction of the movable plate 65 is not limited to the left and right direction, but may also be the front and back direction, the up and down direction, or any inclined direction.

[0078] (3) In the upper lamp 51 of the above embodiment, the release lever 67 as a release operation part for disengaging the detachable unit 70 is provided on the rear side of the front door 12 so as to be slidable left and right, but this is not limited thereto and it may be provided in a hidden position, such as on the lower side of the top surface of the upper unit 12a. Furthermore, the release operation part is not limited to one that slides left and right, but may also slide back and forth, up and down, or rotate. Furthermore, the release operation part may be provided with a locking mechanism that restricts its operation.

[0079] (4) In the upper lamp 51 of the embodiment, the board 62 of the fixed performance unit 60 includes a first light source 62A and a second light source 62B as multiple light sources. However, this is not limited to this. The board may be divided into a board with a light source for forward illumination and a board with a light source for upward illumination. Furthermore, the second light source 62B of the board 62 is not limited to being composed of a side-view LED, but may also be an LED for forward illumination. Furthermore, the light guide plate 74 is not limited to being formed with a crank-shaped cross section having a first light guide portion 74A and a second light guide portion 74B, but may be divided into a light guide plate for forward illumination and a light guide plate for upward illumination. Furthermore, the light sources and light guide plates of the board are not limited to two types, one for forward illumination and one for upward illumination, but may be light sources and light guide plates oriented in any direction, such as for intermediate heights, rightward illumination, or leftward illumination.

In the gaming machine according to Feature A1 of the present invention, the cylindrical portion has first wall portions (62A) and second wall portions (62B) arranged alternately in the circumferential direction, and the communication passage is provided between the first wall portions and the second wall portions; the first wall portion has a first radial wall (62C) extending in a radial direction and a first circumferential wall (62D) extending in a circumferential direction and intersecting an intermediate portion of the first radial wall, and is formed in a cross-shaped cross section; the second wall portion has a second radial wall (62E) extending in the radial direction, a second outer peripheral wall (62F) extending in the circumferential direction and intersecting the outer peripheral side of the second radial wall, and a second inner peripheral wall (62G) extending in the circumferential direction and intersecting the inner peripheral side of the second radial wall, and is formed to have an I-shaped cross section; the opening is formed by a gap between the first radial wall of the first wall portion and the second outer circumferential wall of the second wall portion, The first peripheral wall of the first wall portion and the second inner peripheral wall of the second wall portion are provided to overlap each other in the radial direction. A gaming machine characterized by:

[0084] According to feature A2 of the present invention group, the tubular portion has a first wall portion and a second wall portion, a communicating passage is provided between the first wall portion and the second wall portion, and the first peripheral wall of the first wall portion and the second inner peripheral wall of the second wall portion are arranged to overlap radially, so that the communicating passage is formed in a crank shape that is bent four times, which makes it possible to more reliably prevent fraudulent acts.

[0085] Feature A3. In the gaming machine according to Feature A1 or Feature A2 of the present invention, The rear cover has an extension cylindrical portion (63) that extends from the cylindrical portion toward the inside of the housing and surrounds the rear end of the speaker, The extension cylindrical portion is formed to have a small diameter cylindrical portion (63A) having an outer diameter smaller than that of the cylindrical portion, and a flange portion (63B) bent radially inward from the rear end of the small diameter cylindrical portion and extending along the rear end of the speaker. A gaming machine characterized by:

[0086] According to feature A3 of the present invention group, the rear cover has an extension cylindrical portion, which has a small diameter cylindrical portion and a flange portion, and the flange portion is arranged along the rear end of the speaker, thereby eliminating the gap between the rear cover and the speaker and more reliably preventing fraudulent acts.

[0087] According to the feature group A of the present invention, the communication passage of the rear cover is formed in a crank shape that is bent at least twice, thereby making it possible to solve the following problems.

[0088] Conventionally, typical examples of gaming machines include slot machines and pachinko machines. For example, slot machines and pachinko machines are equipped with speakers for emitting various gaming sounds forward from the front door of the gaming machine (see, for example, Patent Document 1). The speaker is installed inside a speaker grill that has multiple holes in the front door body, and since there is a concern that unauthorized access to the inside of the housing may be gained by piercing the speaker with a wire or the like, a back cover is attached to the back side of the speaker to prevent such unauthorized access.

[0089] However, conventional back covers have a small opening that connects the inside of the back cover to the inside of the housing, making it difficult to ensure the speaker's sound quality and sound pressure.On the other hand, if the opening is made larger, it becomes easier for unauthorized access to occur through the opening, which is problematic from the perspective of preventing fraud.

[0090] <Feature AA group> Feature AA1. A gaming machine equipped with a light emitting means (60) having a substrate (63) on which a light source (63A) is mounted and a light guide plate (64) that guides light emitted from the light source, The light guide plate has a first plate portion (64A) extending in a first direction and having the light source disposed at one end thereof, a second plate portion (64B) bending from the other end of the first plate portion and extending in a second direction, and a reflecting portion (64C) that reflects the light guided to the first plate portion to the second plate portion, The second plate portion is formed so that the plate thickness gradually decreases from the reflecting portion toward the tip side in the second direction, and is configured to have a diffusing portion (second diffusing portion 64F) that diffuses light guided to the second plate portion. A gaming machine characterized by:

[0091] According to Feature AA1 of the present invention group, the light guide plate of the light emitting means has a first plate portion, a second plate portion, and a reflecting portion. The second plate portion is formed so that its thickness gradually decreases toward its tip end, and is configured with a diffusing portion that diffuses light guided into the second plate portion, thereby enabling a uniform amount of light emitted at each portion of the second plate portion in the second direction to be emitted as a surface emission. That is, light from the light source of the substrate is introduced from one end of the first plate portion and travels in the first direction, then reflected by the reflecting portion and travels through the second plate portion in the second direction, where it is gradually diffused by the diffusing portion of the second plate portion, whose thickness gradually decreases. In this way, uniform surface emission can be obtained at the second plate portion, which is distant from the light source and intersects with the irradiation direction (first direction) of light from the light source, eliminating the need for another light source corresponding to the second plate portion and simplifying the structure of the light emitting means.

[0092] Feature AA2. In the gaming machine described in feature AA1 of the present invention group, The diffusion portion of the second plate portion is formed in a stepped shape from the reflection portion toward the tip side in the second direction. A gaming machine characterized by:

A gaming machine characterized by:

[0095] According to feature AA3 of the present invention group, the diffusion portion is formed in a continuous band-like and uneven shape along a direction perpendicular to the second direction when viewed in a plane, thereby enabling light within the second plate portion to be diffused uniformly.

[0097] According to feature AA4 of the present invention group, a diffusion section is formed on the inner surface of the second plate section bent from the first plate section, so that the light diffused by the diffusion section can be emitted from the outer surface of the second plate section.

[0098] According to the group AA of features of the present invention, the amount of light emitted can be made uniform and emitted from the surface at the second plate portion, which is away from the light source and intersects with the direction of light irradiation from the light source, thereby solving the following problems.

[0099] Conventionally, typical examples of gaming machines include slot machines and pachinko machines. For example, slot machines and pachinko machines are equipped with various light-emitting devices (light-emitting means) on the top, bottom, left and right sides of the gaming machine body (see, for example, JP 2016-185293 A). These light-emitting devices are configured to include a board on which a light source is mounted, a light guide plate that guides light emitted from the light source, and a cover that covers the front side of the board and the light guide plate. In this light-emitting device, light emitted from the light source on the board is diffused through the light guide plate and then emitted, causing the cover to emit light.

[0100] However, in conventional light-emitting means, light from the light source is introduced from one end face of the light guide plate, diffused while traveling in one direction within the light guide plate, and emitted from the surface of the light guide plate toward the cover. Therefore, as the light guide plate becomes longer and the distance from the light source increases, the amount of emitted light becomes insufficient, making it difficult to obtain uniform surface emission. For this reason, it becomes necessary to uniform the amount of light emitted over the entire light guide plate by arranging another light source on the other end face of the light guide plate, which causes the problem of the structure of the light-emitting means becoming complicated and large.

[0101] <Features AB group> Feature AB1.

That is, light from the light source of the substrate is introduced from one end of the first plate portion and travels in the first direction, then reflected by the reflecting portion and travels in the second direction within the second plate portion, where it is sequentially diffused by the diffusing portion formed in a stepped shape in the second plate portion. In this way, uniform surface emission can be obtained at the second plate portion, which is distant from the light source and intersects with the irradiation direction (first direction) of light from the light source, eliminating the need to prepare another light source corresponding to the second plate portion and simplifying the structure of the light emitting means.

A gaming machine characterized by:

[0104] According to feature AB2 of the present invention group, the light within the second plate portion is gradually diffused by the diffusion portion of the second plate portion, the thickness of which gradually decreases, thereby making it possible to make the amount of light emitted from the second plate portion more uniform.

[0105] Feature AB3. In the gaming machine according to feature AB1 or AB2 of the present invention, The diffusion portion of the second plate portion is formed in a continuous band-like uneven shape along a direction perpendicular to the second direction in a plan view of the second plate portion.

In this light-emitting device, light emitted from the light source on the board is diffused through the light guide plate and then emitted, causing the cover to emit light.

[0111] However, in conventional light-emitting means, light from the light source is introduced from one end face of the light guide plate, diffused while traveling in one direction within the light guide plate, and emitted from the surface of the light guide plate toward the cover. Therefore, as the light guide plate becomes longer and the distance from the light source increases, the amount of emitted light becomes insufficient, making it difficult to obtain uniform surface emission. For this reason, it becomes necessary to uniform the amount of light emitted over the entire light guide plate by arranging another light source on the other end face of the light guide plate, which causes the problem of the structure of the light-emitting means becoming complicated and large.

[0112] <Characteristic AC group> Feature AC1. A gaming machine equipped with a light emitting means (60) having a substrate (63) on which a light source (63A) is mounted and a light guide plate (64) that guides light emitted from the light source, The light guide plate is formed so that the light source is disposed at one end thereof and the plate thickness gradually decreases toward the other end thereof, and is configured to have a diffusion section (second diffusion section 64F) that diffuses the light guided to the light guide plate. A gaming machine characterized by:

[0113] According to Feature AC1 of the present invention group, the light guide plate of the light emitting means has the light source disposed at one end thereof, is formed so that its thickness gradually decreases toward the other end thereof, and is configured with a diffusion section that diffuses the light guided by the light guide plate, thereby enabling the amount of light emitted at the other end to be uniform and emitted as a surface. That is, light from the light source of the substrate is introduced from one end of the light guide plate and travels toward the other end, where it is diffused sequentially by the diffusion section whose thickness gradually decreases toward the other end. In this way, uniform surface emission can be obtained at the other end away from the light source, eliminating the need to provide another light source at the other end thereof and simplifying the structure of the light emitting means.

[0114] Features AC2. In the gaming machine according to feature AC1 of the present invention, The diffusion portion is formed in a stepped shape toward the other end of the light guide plate. A gaming machine characterized by:

[0115] According to feature AC2 of the present invention group, the amount of light emitted from the light guide plate can be made more uniform by gradually diffusing the light using a diffusion section formed in a stepped pattern toward the other end of the light guide plate.

[0116] Features AC3. In the gaming machine according to feature AC2 of the present invention, The diffusion portion is formed in a continuous band-like irregular shape along a direction perpendicular to a direction from one end of the light guide plate to the other end thereof in a plan view of the light guide plate. A gaming machine characterized by:

[0117] According to feature AC3 of the present invention group, the diffusion portion is formed in a continuous band shape and uneven shape in a plan view, so that the light inside the light guide plate can be diffused uniformly.

[0118] According to the features AC group of the present invention, the amount of emitted light can be made uniform and surface-emitted on the other end side of the light guide plate away from the light source, thereby solving the following problems.

[0119] Conventionally, typical examples of gaming machines include slot machines and pachinko machines. For example, slot machines and pachinko machines are equipped with various light-emitting devices (light-emitting means) on the top, bottom, left and right sides of the gaming machine body (see, for example, JP 2016-185293 A). These light-emitting devices are configured to include a board on which a light source is mounted, a light guide plate that guides light emitted from the light source, and a cover that covers the front side of the board and the light guide plate. In this light-emitting device, light emitted from the light source on the board is diffused through the light guide plate and then emitted, causing the cover to emit light.

[0120] However, in conventional light-emitting means, light from the light source is introduced from one end face of the light guide plate, diffused while traveling in one direction within the light guide plate, and emitted from the surface of the light guide plate toward the cover. Therefore, as the light guide plate becomes longer and the distance from the light source increases, the amount of emitted light becomes insufficient, making it difficult to obtain uniform surface emission. For this reason, it becomes necessary to uniform the amount of light emitted over the entire light guide plate by arranging another light source on the other end face of the light guide plate, which causes the problem of the structure of the light-emitting means becoming complicated and large.

[0121] <Feature AD group> Feature AD1. A gaming machine equipped with a light emitting means (70) having a board (71) on which light sources (71A, 71B, 71C) are mounted and a cover (translucent cover 73) that transmits light irradiated from the light sources, the substrate and the cover are provided non-parallel to each other, and in a cross-sectional view of the light-emitting means, a distance between one end of the substrate and one end of the cover is set to be larger than a distance between the other end of the substrate and the other end of the cover; the light source includes a first light source (71A, 71B) and a second light source (71A, 71C) having a lower brightness than the first light source; The first light source emits light toward one end of the cover, and the second light source emits light toward the other end of the cover. A gaming machine characterized by:

[0122] According to Feature AD1 of the present invention group, the light-emitting means has a first light source irradiating light toward one end where the distance between the substrate and the cover is large, and a second light source having lower brightness than the first light source irradiating light toward the other end where the distance between the substrate and the cover is small, thereby making it possible to equalize the light that reaches the cover. Therefore, even if the substrate and the cover are not arranged parallel to each other, the light that passes through the cover can be made uniform, thereby simplifying the structure of the light-emitting means and increasing the degree of freedom in the arrangement of the substrate and the cover, thereby improving the design of the light-emitting means.

[0123] Feature AD2. In the gaming machine according to feature AD1 of the present invention, The light source (71A) is composed of a side-view LED, and the first light source irradiates high-intensity light from the side-view LED along the substrate, and the second light source irradiates low-intensity light from the side-view LED toward the front of the substrate. A gaming machine characterized by:

[0124] According to feature AD2 of the present invention group, the light source is configured as a side-view LED, which simplifies the structures of the substrate and the light source.

[0125] Feature AD3. In the gaming machine according to feature AD1 of the present invention, the first light source (71B) is configured by a first LED that is disposed on one end side of the substrate and emits light with high luminance toward the front of the substrate; The second light source (71C) is arranged on the other end side of the substrate and is composed of a second LED that irradiates light with low brightness toward the front of the substrate. A gaming machine characterized by:

[0126] According to feature AD3 of the present invention, by selecting the first light source and the second light source to have appropriate brightness and arranging them at appropriate positions on one end and the other end of the substrate, the amount of light reaching the cover can be appropriately set, and the light passing through the cover can be made uniform.

[0127] Feature AD4. In the gaming machine according to any one of Features AD1 to AD3 of the present invention, The light emitting means further includes a reflector 72 provided on one end side of the substrate and the cover to reflect the light emitted from the primary light source. A gaming machine characterized by:

[0128] According to feature AD4 of the present invention, by further providing a reflector that reflects the light emitted from the first light source, the light from the first light source can be reflected in an appropriate direction before reaching the cover.

[0129] According to the AD group of features of the present invention, even if the substrate and cover are arranged at an angle to each other, the light from the light source on the substrate can reach the cover evenly, thereby making the light passing through the cover uniform, thereby solving the following problems.

[0130] Conventionally, typical examples of gaming machines include slot machines and pachinko machines. For example, slot machines and pachinko machines are equipped with various light-emitting devices (light-emitting means) on the top, bottom, left and right sides of the gaming machine body (see, for example, JP 2016-185293 A). These light-emitting devices are configured to include a board on which a light source is mounted, a light guide plate that guides light emitted from the light source, and a cover that covers the front side of the board and the light guide plate. In this light-emitting device, light emitted from the light source on the board is diffused through the light guide plate and then emitted, causing the cover to emit light.

[0131] However, in conventional light-emitting means, although the light from the light source is made uniform by a light guide plate and the uniform light is emitted to the cover, it is difficult to make the light uniform without using a light guide plate, and there is a problem that the structure of the light-emitting means becomes complicated and large. On the other hand, when the substrate and the cover are arranged parallel to each other and light is irradiated directly from the light source to the cover, it is difficult to enhance the design of the light-emitting means because of restrictions on the arrangement and shape of the cover.
