Description

The present invention relates to a gaming machine such as a slot machine, and more particularly to a gaming machine capable of improving the arrangement structure of a board assembly including a sub board for performing predetermined presentation display control.

  In general, as a gaming machine, for example, a slot machine, after rotating a rotating reel of three horizontal rows having a plurality of symbol marks composed of a plurality of patterns in the circumferential direction based on a start lever operation, three stop buttons By pressing each of the buttons, the reel reels corresponding to each button are stopped in sequence, and when a predetermined pattern of the symbol marks provided on each reel reel is matched, a large number of coins are received as coin trays. It is known to have a structure released into

  In the slot machine as described above, after a certain period of time, events such as new clothing are implemented for the purpose of changing the player's eyes, etc. In order to reduce the labor and cost required for new clothing, the entire slot machine is Instead of exchanging, only a part of it is exchanged on a small scale.

  As described above, as a technique for implementing a small-scale renovation without replacing the slot machine itself, for example, a method in which only the front door is replaced is known. According to this method, it is possible to make an appearance change by exchanging only a part that is easily touched by a player or a part that is easy to enter the field of view.

  By the way, in recent years, slot machines equipped with a liquid crystal display device have become the mainstream, and the production by the liquid crystal display device has become an extremely important factor in the progress of the game. However, as described above, only the front door should be replaced. In this method, since the control circuit for the liquid crystal display device arranged on the back side of the housing that supports the front door so that it can be opened and closed cannot be replaced, it is impossible to change the display content of the liquid crystal display device, which is an important element. could not.

  In other words, when trying to implement a new event using the above-mentioned conventional method, it is necessary to replace the main control board disposed in the housing and including the control circuit, but also to replace the main control board. Including them makes it difficult to achieve the goal of labor and cost savings during a new event.

  Therefore, a slot machine has been proposed in which a display control circuit for controlling a liquid crystal display device that can be viewed from the front side is attached to the back of the front door so that the display control circuit can be replaced when only the front door is replaced. (For example, refer to Patent Document 1).

JP 2001-170249 A (see FIGS. 6 to 8)

  By the way, in the conventional slot machine described in Patent Document 1, various parts necessary for a game are arranged on the back side of the front door, and the spinning reel device visually recognizes the spinning reel. For the purpose of improving the performance, the reel reel is arranged close to the front door side. For this reason, especially in the vicinity of the spinning reel at the front door, there are many space restrictions on component mounting, so even if a larger display control circuit or the like is adopted in response to the improvement of the display function, it is There was a limit. Similarly, it is intended to adopt a larger one for the sub-board that performs a predetermined effect display according to the effect control signal supplied from the microprocessor in the main control board and the sub-board assembly that accommodates the sub-board. However, due to space constraints, its mounting was limited. In addition, for example, a method of mounting the sub-board on the back surface of the liquid crystal display device is also conceivable, but in that case, the substrate assembly protrudes in the back direction as much as it is stacked and thickened. There is a risk that inconvenience such as buffering may occur.

The present invention has been made in view of such conventional problems, and is configured to be relatively large as compared with the prior art by improving the arrangement structure of the substrate assembly that accommodates the control substrate such as the sub-substrate. An object of the present invention is to provide a gaming machine that can be mounted very easily while effectively using the space on the back side of the front door while adopting the above-described board assembly .

The invention according to claim 1 is a housing, a front door supported by the housing so as to be openable and closable, a display device supported by the front door, and a substrate disposed for performing predetermined control for presentation. In a gaming machine comprising an assembly and a spinning reel device disposed on the back side of the display device,
A case member having a protruding portion protruding from the back surface of the display device to the upper side of the spinning reel device;
A connecting member connected to the upper surface of the protruding portion and extending to the back side of the display device along the upper inner surface of the housing;
Supporting the bottom of the substrate assembly along the extending direction of the connecting member to the connecting member ;
The case member has a cover main body, and the cover main body has a housing portion that has a substantially inverted triangular shape in a side view as the protruding portion that protrudes above the rotating reel device on the back side of the display device. And the connecting member is fixed to the upper surface of the rear portion of the housing portion and extends rearward .

  Note that the phrase “upper” such as “upper” in the present invention is based on the general concept of “lower” as the direction of gravity, and means the direction opposite to the direction of gravity (upward).

The invention according to claim 2 is the gaming machine invention according to claim 1, wherein the board assembly is formed in a substantially rectangular parallelepiped shape, and its long edge portion is formed along the width direction of the front door. It is characterized by being supported by.

According to the first aspect of the present invention, the bottom part of the substrate assembly is supported by the connecting member along the extending direction of the connecting member, and the cover body of the case member is the rotating reel on the back side of the display device. Since the upper part has a housing part that has a substantially inverted triangular shape in side view as a projecting part that projects to the upper side of the device, and a connecting member is fixed to the rear upper surface of the housing part and extends rearward, It is possible to mount a larger board assembly easily while using the upper space very effectively and greatly reducing space constraints. Moreover, by supporting the bottom portion of the board assembly by the connecting member, when the integrated circuit device is built in the board assembly , the front surface direction of the integrated circuit device can be opened (free). Even when electronic components with a relatively large heat generation, such as a CPU (Central Processing Unit) with a high clock frequency, are mounted as the integrated circuit device, the cooling effect is extremely effective compared to conventional mounting methods. Can be expected.

According to the second aspect of the present invention, since the board assembly is configured in a substantially rectangular parallelepiped shape and its long edge is supported along the width direction of the front door, Thus, it is possible to further effectively use the space above the rotating reel device.

  Hereinafter, as an embodiment of the gaming machine of the present invention, a slot machine installed in a playground or the like will be described with reference to FIGS.

Each of these reel reels 27a has the symbols and the like appearing after rotating and stopping. It can be clearly seen from the player side through the transmission window 19. The transmission window 19 is made of a transparent hard plastic plate or the like so that the reel reel device 27 can be reliably protected from the outside.

  Next, the rear structure of the front door 12 will be described in detail with reference to FIG. That is, the front door 12 has a transmission window 19 at the center in the vertical direction, and a nylon made of a plurality of harnesses (not shown) is supported on the left side of the transmission window 19 in a bundled state. A harness clamp 52 is provided. Even if the number of necessary wirings is increased due to the relatively large liquid crystal display panel 15 and the integrated circuit device 62, the transmission window is formed in such a manner that a large number of harnesses are compactly bound by the harness clamp 52. It is possible to perform wiring through one side portion of 19, that is, a path that is not easily affected by heat, and it is possible to eliminate the complexity of assembly. Further, a cold cathode tube 46 is disposed above the transmission window 19, and a liquid crystal assembly 35, a sub substrate assembly 36, and a game state display substrate 37 are sequentially disposed above the cold cathode tube 46.

  Here, with reference to FIG. 4, the structure of the liquid crystal display panel and the like will be schematically described. That is, the liquid crystal display panel 15 has a liquid crystal main body 57 to be described later. As shown in FIG. 4, the liquid crystal main body 57 has a flat transmissive color liquid crystal display LQD and the rear surface of the transmissive color liquid crystal display LQD. A transparent light guide plate TPB disposed in close contact with the light guide plate, a cold cathode tube 46 disposed above the light guide plate TPB, and a reflector RFM disposed on the back surface of the light guide plate TPB.

The above-described transmission window 19 is defined by the sealing member SEL interposed between the substrates SB1 and SB2, and the liquid crystal LQ is filled in the inner region of the transmission window 19 defined by the sealing member SEL. It has not been. Further, since the reflection plate RFM is provided only on the back surface of the transmission window 19 except for the transparent window 19, the area of the liquid crystal body 57 where the transmission window 19 is formed has a high light transmittance and displays an image. It is a non-display area that cannot be done. That is, the liquid crystal display panel 15 having the liquid crystal main body 57 includes the transmission window 19 through which the central portion of the color liquid crystal display LQD formed so as to extend over the entire front surface of the spinning reel device 27 is rectangular. In other words, it is configured as a so-called donut-shaped liquid crystal display panel.

  Next, referring to FIG. 5 and FIG. 6 together, the liquid crystal display panel (display device) 15 and its peripheral structure are shown in the left-right direction in FIG. 5 and the diagonal left-right direction in FIG. Will be described in detail.

  The liquid crystal cover main body 77 has a rear inclined surface 77d which is inclined at a predetermined angle so as to protrude rearward (back side of the liquid crystal display panel 15) as the upper side as a whole. The first control cover 82 is inclined at the same angle as the rear inclined surface 77d inside the liquid crystal cover main body 77, that is, the rear inclined surface inclined at a predetermined angle so as to protrude rearward as a whole upwards. 82d.

  In addition, a fever lens 93, a reflector 95, an effect lamp 96, and a lamp substrate 97 are arranged in this order from the front side of the front door 12 above the front portion of the front door 12. A hook member (first engagement member) 67, a hook receiving member (second engagement member) 69, a slide hinge 99, and a sub-board assembly 36 are arranged. A pair of hook members 67 are provided in the vicinity of both upper ends of the liquid crystal assembly bracket 56, and the hook receiving members 69 are arranged at both upper ends of the liquid crystal cover main body 77 so as to face the pair of hook members 67, respectively. A pair is provided in the vicinity. Further, brackets for fixing the liquid crystal assembly 35 to the front door 12 side on both sides of each hook receiving member 69 in the upper portion of the cover body 77 in a state where the liquid crystal assembly 35 is hooked on the hook member 67 by the hook receiving members 69. 54 is provided. Each bracket 54 has a hole 54a for inserting a fixing screw (not shown).

  A sub board mounting bracket (connecting member) 58 is fixed to the upper surface 77c of the liquid crystal cover main body 77 so as to protrude rearward, and the sub bracket 58 extends along the extending direction thereof. A substrate assembly 36 is mounted. That is, the sub board assembly 36 is supported via the sub board mounting bracket 58 so as to extend in a direction substantially orthogonal to the vertical direction in which the cover body 77 extends.

  A liquid crystal assembly 35 as a display assembly is configured by the liquid crystal main body 57 and the cover main body 77 having the sub-substrate assembly 36. Further, a liquid crystal assembly (display assembly) 35 in a state in which these members 67 and 69 are relatively engaged by a hook member 67 as a first engaging member and a hook receiving member 69 as a second engaging member.

  The liquid crystal assembly 35 includes a plurality of hook receiving members 69 provided on the upper portion of the cover main body 77 and hooked on the hook members 67 provided on the upper portion of the liquid crystal assembly bracket 56. A fixing screw (not shown) is inserted into the hole 54a of the bracket 54 (see FIG. 6), and the tip of the screw is screwed into a corresponding position on the back surface of the front door 12 to be fixedly mounted.

  Next, the structure shown in FIG. 6 will be described in more detail with reference to FIG. FIG. 7 is an exploded perspective view showing a state viewed from the opposite direction of FIG. 6, and shows a state in which the inner first control cover 82 is drawn forward from the liquid crystal cover body 77.

  That is, as shown in FIG. 7, the liquid crystal cover main body 77 attached to the front center portion of the front door 12 has a first control cover 82 drawn forward. The reel window 79 is configured by the reel window 79 a of the first control cover 82 and the reel window 79 b of the liquid crystal cover main body 77. The first control cover 82 has an accommodating portion 82a on the upper side of the reel window 79a, and an exhaust port 63 on the upper surface of the accommodating portion 82a. The accommodating portion 82a is a protruding portion that protrudes above the rotating reel device 27 on the back side of the liquid crystal display panel 15, and is configured in a substantially inverted triangular shape in side view so as to accommodate various components. Further, the cover body 77 has a housing portion 77a on its upper side that has a substantially inverted triangular shape in side view and can accommodate the housing portion 82a as a projecting portion that projects above the rotating reel device 27 on the back side of the liquid crystal display panel 15. is doing. The accommodating portion 82a and the accommodating portion 77a have an upper surface 82e and an upper surface 77c (see FIG. 7) that are substantially parallel to the upper inner surface of the housing 11, respectively, and slightly in the vertical direction (the vertical direction in FIG. 9). Rear inclined surfaces 82d and 77d each having a shape inclined rearward are provided.

  The hook receiving members 69 described above are coupled to the positions corresponding to the pair of sub-board mounting brackets 58 on the upper surface 77c of the accommodating portion 77a. A cold cathode tube 46 is provided above the reel window 79 of the liquid crystal cover main body 77, and an inverter 45 is provided on one side in the width direction of the liquid crystal cover main body 77 (left portion in the figure). A central relay board 76 is disposed below the rear portion of the liquid crystal cover main body 77, and a setting button 75 is disposed in the vicinity of the inverter 45 on the central relay board 76. A central relay board cover 53 is provided so as to cover the back of the central relay board 76 including these setting buttons 75.

  Next, referring to FIG. 7 and FIG. 8 together, a structure in which the sub-board assembly 36 and the like are arranged by effectively using the space in the casing 11 of the slot machine 10 will be described.

  As shown in the figure, a main board 25 is mounted on an upper portion of the rear wall surface of the housing 11, and a rotating reel device 27 having a rotating reel 27 a is disposed below the front of the main board 25. In addition, a reel control board 100 is disposed on the upper part of the rotating reel device 27. A sub board assembly 36 is attached to a sub board mounting bracket 58 that protrudes rearward (on the right side in FIG. 8) at the upper part of the cover body 77 so as to be substantially parallel to the inner upper surface of the housing 11.

  By the way, as can be understood by referring to FIGS. 5 and 8 together, the circular reel reel 27a in the side view of the rotary reel device 27 can be provided to the transmission window 19 (see FIG. 1) of the liquid crystal display panel 15. In the case of making them as close as possible, the space S sandwiched between the cover main body 77 and the upper part of the reel reel device 27 in the housing 11 has no room, and the sub-board assembly that is relatively large in this embodiment is used. It is expected that it will be difficult to accommodate 36. However, in the present embodiment, the sub-board assembly 36 is accommodated with a margin in a form that effectively uses the relatively narrow space S on the spinning reel device 27.

  That is, in the present embodiment, in order to effectively use the space S, the upper surface 77c of the housing portion 77a of the cover body 77 is formed so as to be substantially parallel to the upper inner surface of the housing 11, and this A pair of sub-board mounting brackets 58 is fixed to the upper surface 77c of the shape. As a result, as can be understood from FIG. 5, the pair of brackets 58 extend in a shape slightly inclined downward at the rear according to the inclination of the front door 12, but are substantially parallel to the upper inner surface of the housing 11. Thus, the upper portion of the reel reel device 27 is disposed so as to protrude rearward.

  In a conventional slot machine or the like, the space for accommodating the reel reel device in the housing is more circular because the reel reel of the reel reel device is circular when viewed from the side. It was something that had to be considered. For this reason, in particular, in the arrangement of the size larger than the conventional type due to the improved function, such as the sub-board assembly 36 in the present embodiment, it is difficult to accommodate in the narrow space of the conventional type. However, according to the arrangement structure in the present embodiment, the sub-board assembly 36 whose bottom is supported on the sub-board mounting bracket 58 is rearward in a state substantially parallel to the upper inner surface of the housing 11 like the sub-board mounting bracket 58. Since it is extended, a margin can be provided in the arrangement of the sub-board assembly 36. That is, since the bottom portion of the sub board assembly 36 is supported by the bracket 58 so as to extend along the direction in which the sub board mounting bracket 58 extends, the space S on the upper side of the spinning reel device 27 is used extremely effectively. As a result, it is possible to easily mount a larger sub-board assembly 36 while greatly reducing the restrictions. In addition, since the bottom portion of the sub-board assembly 36 is supported by the sub-board mounting bracket 58, the front surface direction of the integrated circuit device is opened when the integrated circuit device (not shown) is built in the board assembly 36. (Free). Therefore, even when an electronic component having a relatively large amount of heat generation, such as a CPU having a high clock frequency, is mounted as the integrated circuit device, an extremely effective cooling effect is expected as compared with the conventional mounting method. can do. Moreover, as can be understood from FIGS. 2, 6 and 7, the sub-board assembly 36 is configured in a rectangular parallelepiped shape, and its long edge (that is, long side) is arranged in the width direction of the front door 12 (that is, the figure). 2), the amount of protrusion of the housing 11 in the front-rear direction is suppressed, and the space S can be used more effectively.

  Next, referring to FIGS. 9 and 10 together, a heat radiating structure capable of effectively radiating heat to the liquid crystal control board 66 provided in the slot machine 10 will be described. FIG. 9 is a side cross-sectional view showing a state in which the state of FIG. 5 is viewed in the longitudinal direction (vertical direction in FIG. 9) at a location different from FIG. FIG. 10 is a perspective view showing a state in which components housed inside the first control cover 82 are disassembled.

  That is, as shown in FIG. 9, the first control cover 82 is accommodated inside the accommodating portion 77a of the cover main body 77 so as to be in close contact with the inner surface of the accommodating portion 77a. A liquid crystal control board 66 is mounted on a rear inclined surface 82d on the inner side of the first control cover 82 via predetermined means such as a rib protruding from the rear inclined surface 82d. As shown in FIG. 10, the liquid crystal control board 66 includes liquid crystal control boards 66a and 66b having different sizes. In FIG. 9, reference numeral 106 denotes a connector disposed on the back surface of the liquid crystal control board 66, and reference numeral 85 denotes an exhaust fan.

  As described above, the metal second control cover 83 maintains a predetermined state on the front surface of the chip-like liquid crystal control board 66 accommodated and disposed along the rear inclined surface 82d of the first control cover 82. Installed. The second control cover 83 has a notch 83c at a position that can face the exhaust port 64 of the first control cover 82, and a close contact surface 83b at a position that faces the integrated circuit device 62. A heat sink 65 is attached in close contact with the front surface side (right side in FIG. 9) of the contact surface 83b. The integrated circuit device 62 includes integrated circuit devices 62a and 62b having different sizes and functions. The heat sink 65 is composed of two heat sinks 65a and 65b having the same size and number of heat dissipating fins so that these integrated circuit devices 62a and 62b can be opposed to each other.

  The heat sinks 65a and 65b are in close contact with the integrated circuit devices 62a and 62b via the close contact surface 83b of the second control cover 83, and are generated during operation of the integrated circuit devices 62a and 62b and transmitted via the close contact surface 83b. It is a metal part having a function of radiating the generated heat to the surrounding air and cooling it. Usually, the heat sink is mounted on the liquid crystal control board 66 side on which the integrated circuit device 62 is mounted. In that case, it may be possible to forcefully fix the heat sink to the liquid crystal control board 66. There is a possibility that the substrate 66 may be inconvenienced such as being cracked and damaged. However, according to the arrangement structure of the heat sink 65 described above in the present embodiment, it is possible to reliably prevent the occurrence of such inconvenience that causes such damage.

  Further, as can be understood by referring to FIG. 9 and FIG. 10 together, the rear inclined surface 82d of the first control cover 82 corresponds to the hypotenuse when the accommodating portion 82a is compared to a right triangle. The area is increased compared to the case where the surface is formed along the vertical direction 9. Therefore, since the liquid crystal control board 66 having a larger size is disposed along the rear inclined surface 82d that is formed wider inside the case member including the cover main body 77 and the first control cover 82, the liquid crystal The integrated circuit device 62 and other electronic components to be mounted on the control board 66 can also be mounted with a space in terms of size and performance. Further, the rear inclined surface 82d and the rear inclined surface 77d have a shape that is inclined rearward toward the upper side along the vertical line, so that the reel reel device is disposed at the lower rear portion of the inclined surfaces 82d and 77d. While the outer diameter (reel diameter) of the 27 reel reels 27a is larger than before, the front door 12 can be made closer to the front surface side (that is, the transmission window 19 side). Thereby, the visibility with respect to the spinning reel 27a from the player side can be further improved. Although depending on the sizes of the casing 11 and other components, the inclination angles θ of the rear inclined surface 82d and the rear inclined surface 77d are preferably set within a range of 10 ° to 30 °, for example.

  An exhaust port 63 is formed on the upper surface of the second control cover 83, and an inverter board 90 and noise prevention plates 91a and 90b are arranged on the right side of the heat sink 65 in FIG.

  Next, a heat dissipation structure for the heat sink 65 and the like described above will be described with reference to FIGS. That is, in the heat dissipation structure, the heat sink 65 is positioned at the center in the vertical direction, the exhaust port 63 is disposed above, and the intake port 89 is disposed below. The ports 64 are arranged in a straight line in the vertical direction.

  As shown in FIG. 10, the exhaust port 63 is formed in the upper surface 82e of the first control cover 82 at a position facing the exhaust fan 85 provided on the inner surface side thereof, and the exhaust port 63 in the accommodating portion 82a is formed in the exhaust port 63. An intake port 89 is formed at the opposing position. The integrated circuit device 62 and the heat sink 65 are disposed on a vertical path connecting the exhaust port 63 and the intake port 89 in a straight line.

  According to this structure, the exhaust port 63 and the intake port 89 that are arranged in a straight line with the heat sink 65 positioned in the middle are provided, and the exhaust fan 85 that faces the exhaust port 63 is provided. Thus, an air flow passage through which air can flow toward the exhaust fan 85 can be realized, and the air flow sucked from the intake port 63 is directly applied to the heat sink 65 without diffusing, so that the heat sink 65 from the integrated circuit device 62 is applied. Thus, the heat transferred to can be effectively discharged from the exhaust port 63, and the integrated circuit device 62 can be cooled well.

  That is, when the exhaust fan 85 is operated, the air sucked from the intake port 89 absorbs the heat of the heat radiating fins via the heat sink 65 and then moves outward from the upper exhaust port 64 (that is, the housing). 11) to the internal space. The air flow path at this time is drawn from the air intake port 89 and supplied directly to the heat sink 65, while the heat absorbed from the heat sink 65 is radiated from the exhaust port 64 positioned above the heat sink 65. It is exhausted efficiently. As a result, the integrated circuit device 62 is cooled extremely efficiently. Therefore, a heat dissipation structure that can be expected to have an appropriate heat dissipation effect for a relatively large integrated circuit device in recent years is obtained.

  The slot machine 10 having the above configuration functions as shown below. Here, the process of assembling the liquid crystal display panel 15 to the front door 12 will be mainly described.

  That is, prior to the assembling process, a liquid crystal assembly bracket 56 in which the middle panel 55 is assembled is fixed to the front surface of the front door 12, and a pair of hook members 67 provided on the upper portion of the bracket 56 project rearward. Keep in a state to do. The operator visually hooks a pair of hook receiving members 69 projecting above the liquid crystal assembly 35 to the hook member 67 in a state where the liquid crystal assembly 35 is assembled with the liquid crystal main body 57, the cover main body 77, and the like. To release the hand from the liquid crystal assembly 35.

  As a result, the entire weight of the liquid crystal assembly 35 is carried on the liquid crystal assembly bracket 56 side via the hook member 67, and the liquid crystal assembly 35 is suspended. Therefore, the operator can proceed with an extremely easy posture without being forced to work in an unreasonable posture such as holding the liquid crystal display device and fixing it to the front door as in the prior art. A fixing screw is screwed to the front door 12 side via a bracket 54 around the hook receiving member 69, so that the liquid crystal assembly 35 temporarily fixed by the hook member 67 and the hook receiving member 69 is moved to the front door 12 side. It can be fixed regularly.

  As described above, the weight of the liquid crystal assembly 35 can be carried on the liquid crystal assembly bracket 56 mounted on the front door 12 in a state where the hook member 67 and the hook receiving member 69 are relatively engaged. For example, the procedure of simply hooking the hook receiving member 69 on the liquid crystal assembly 35 side to the hook member 67 on the liquid crystal assembly bracket 56 side does not require an operation with an unreasonable posture for holding the liquid crystal assembly 35. Accordingly, the assembly work of the liquid crystal display panel 15 can be carried out in an extremely easy posture without forcing an unreasonable posture, so that the occurrence of inconveniences such as accidental dropping of the liquid crystal display panel 15 and damage can be reliably prevented. , Work efficiency can be greatly improved.

  Further, since the integrated circuit device 62 and other electronic components mounted on the liquid crystal control board 66 are covered with the first control cover 82 made of metal on the inner surface side of the cover body 77, noise to the integrated circuit device 62 and the like. A prevention effect can also be expected, and the slot machine 10 having a structure resistant to internal and external noise can be realized.

  Next, a first modified example in which the present embodiment is partially changed will be described with reference to FIG. This modification is different from the configuration of the present embodiment described above only in that the shape of the hook receiving member 69 is changed to a handle shape, but the other configurations are the same, and therefore common portions are not included. The same reference numerals are given and description thereof is omitted.

  That is, in this modification, the pair of hook members 67 provided on the liquid crystal assembly bracket 56 side are the same as in the previous embodiment, but as shown in FIG. 11, the hooks to be provided on the liquid crystal assembly 35 side. The receiving member is configured as a hook-shaped hook receiving member 92 that can be engaged with and grasped by the hook member 67 over both the pair of hook members 67. The hook receiving member 92 includes a grip portion 92b having a long handle shape that can be gripped, and a pair of bracket portions (fixed portions) that are to be fixed to the liquid crystal assembly 35 at both ends in the longitudinal direction of the grip portion 92b. 92a. When the hook receiving member 92 is engaged with the hook member 67, the hook receiving member 92 is positioned and engaged so that both ends thereof are respectively hooked by the pair of hook members 67, and in this state, bears the weight of the liquid crystal assembly 35. At this time, the operator can easily grip and transport the liquid crystal assembly 35, and can efficiently assemble the transported liquid crystal assembly 35, so that the work efficiency can be improved as well as the transportability. .

  In addition, the hook receiving member 92 is configured such that a fixing bolt 94 is inserted into holes formed in the pair of bracket portions 92 a and is fixed to the cover main body 77 via the bolt 94. That is, the cover main body 77 has a through hole at a position corresponding to the hole of each bracket portion 92a. This through-hole is formed so as to vertically penetrate both the cover body (synthetic resin layer) 77 on the surface side and the first control cover (metal layer) 82 on the inner side thereof, and the bracket portion 92a. In a state in which the hole is opposed to the through hole, the bolt 94 is passed through the through hole from the bracket portion 92a side, and the nut 98 is screwed from the inner surface side of the first control cover 82, so that the hook receiving member 92 is engaged. Can be firmly attached to the cover body 77 side.

  According to this modification having the above-described configuration, the bracket portions 92a at both ends of the hook receiving member 92 are directly fixed to the first control cover 82 having the highest strength on the cover body 77 side via the bolt 94 and the nut 98. Therefore, the rigidity of the support structure of the hook receiving member 92 is increased, the strength against the weight of the liquid crystal assembly 35 held at the time of temporary fixing is further increased, and a liquid crystal assembly assembling structure in which the possibility of breakage is extremely reduced can be realized.

  Next, a second modification in which the heat dissipation structure in FIG. 9 described above is slightly changed will be described with reference to FIG.

  That is, as shown in FIG. 12, a duct hole (opening) 107 is opened at an appropriate position above one side (right side wall) of the front door 12 located on the front surface of the housing 11. As shown in FIG. 13, the duct hole 107 is connected to the intake port 89 of FIG. 9 through a duct 109 extending to a position facing the lower side of the exhaust port 63 (for example, the upper portion of the transmission window 19) and its opening 109a. It communicates with the position. In the case of the second modification, the opening 109a constitutes the intake port 89 in the previous embodiment. In this modification, the duct hole 107 is formed on one side of the front door 12, but the present invention is not limited to this, and the duct hole 107 may be formed on the housing 11 side.

  According to the above configuration of the present modification, the opening (intake port) 109a communicates with the duct hole 107 formed in either the casing 11 or the front door 12 via the duct 109. Even if it is located in the vicinity of the cold cathode tube 46 or the like that illuminates the liquid crystal display panel 15, air that has absorbed heat generated by the cold cathode tube 46 that is a heat generation source is not introduced to the heat sink 65 side. The outside air can be guided to the heat sink 65 through the duct 109. That is, air outside the housing 11 is caused to flow in from the duct hole 107 through a path indicated by an arrow A in FIG. 13 to directly cool the heat sink 65 located between the opening 109a and the exhaust port 63 with the outside air. Therefore, the air from the area where no heat generation source is present is sucked, and the heat sink 65 is radiated and cooled more efficiently by this air, so that the heat radiation efficiency to the liquid crystal control board 66 can be further improved. .

  The gaming machine according to the present invention is useful for a gaming machine having a structure in which a board assembly containing a control board such as a sub-board is mounted on the rear side of the front door, and particularly reduces the size limitation of the board assembly to be mounted. Suitable for gaming machines that need to do.
