When the liquid crystal display device 50 is disassembled, the liquid crystal display panel 52 and the protective panel 53 housed in the panel housing member 51 can be removed from the front side of the image control board assembly 40. Exchange work can be performed.

  Further, as shown in FIG. 8, the rear surface side of the liquid crystal display panel 52 is uniformly and flatly covered with a substantially rectangular sheet metal 55 (metal plate material) having the same size as the liquid crystal display panel 52. The accommodating member 51 accommodates the liquid crystal display panel 52 from the rear side of the sheet metal 55. In a state where the panel storage member 51 stores the liquid crystal display panel 52, the rear surface side of the liquid crystal display panel 52 is shielded by the sheet metal 55, so that the front storage cover 60 side that stores the liquid crystal control board 61 that is a heat generation source. The heat generated in the above is forcibly cooled by the sheet metal 55, heat conduction to the liquid crystal display panel 52 side is cut off, and overheating of the liquid crystal display panel 52 is suppressed.

  As shown in FIG. 9, the front housing cover 60 is formed of a metal box member having an approximately rectangular parallelepiped shape and formed with an opening, and the liquid crystal control board 61 is then directed toward the liquid crystal control board 61. It is installed behind the panel storage member 51 so as to cover from the side. On the left and right sides of the front housing cover 60 and on the panel housing member 51, the frame portions 63, 63 have a depth substantially the same as the depth of the front housing cover 60, and are substantially L-shaped in rear view. Projecting from the panel storage member 51. These frame parts 63, 63 both extend below the front housing cover 60 so that the front ends thereof are opposed to the left and right, and the left and right frame parts 63, 63 are separated from each other below the front housing cover 60. Yes.

  A plurality of substantially circular intake holes 60 a are formed on the lower side surface of the front housing cover 60 so as to penetrate the side surface. On the other hand, the upper side surface of the front housing cover 60 is formed with an exhaust portion 60b that is partially cut off and opens in the front and rear directions so that the air inside the front housing cover 60 can be discharged to the outside. A cooling fan 62 that is operable by receiving power from a power source (not shown) is attached to the front housing cover 60 so as to be housed in the exhaust part 60b. The cooling fan 62 is attached so as to be substantially orthogonal to the surface of the liquid crystal control board 61 that is attached to the rear surface of the panel housing member 51 by a predetermined length by a heat sink 64 (see FIG. 8) described later. When the cooling fan 62 is operated, air is taken into the front housing cover 60 from the outside of the image control board assembly 40 between the left and right frame portions 63 and 63 and through the suction holes 60 a, and this air is sucked into the front housing cover 60. It is introduced into the inside of the front housing cover 60 through the hole 60 a, flows through the front housing cover 60, and is discharged to the outside through the cooling fan 62.

  As shown in FIG. 8, a heat sink 64 having a plurality of heat dissipating portions 64 a extending vertically and arranged side by side is provided inside the front housing cover 60. An opening 59 cut out in a substantially rectangular shape is formed around the heat sink 64 of the panel storage member 51. When the panel storage member 51 is placed on the liquid crystal display panel 52 side (from the state shown in FIG. 8). When the panel storage member 51 is covered so as to cover the sheet metal 55), the front end portion of the heat radiating portion 64a contacts the sheet metal 55, so that the heat generated in the liquid crystal control board 61 and transmitted through the heat sink 64 is transmitted to the sheet metal. It is possible to escape to 55 side effectively. That is, the sheet metal 55 not only protects the liquid crystal display panel 52 from impact but also serves as a heat sink. The sheet metal 55 has substantially the same size as the liquid crystal display panel 52, has a larger heat capacity than a metal sheet having a smaller area, and has a higher thermal conductivity than other materials (such as resin). Since metal is used, it is effective in terms of releasing heat.

  The liquid crystal control board 61 is installed inside the front housing cover 60 and behind the heat sink 64 as described above, with a predetermined length away from the rear surface of the panel housing member 51 by the heat sink 64. The liquid crystal control board 61 is for controlling the display of images such as 3D graphics on the liquid crystal display panel 52, and is accommodated in the rear housing case 70 via the harness 66 according to the game situation on the image display screen 23. It is connected to the production control board 71 that controls the production.

  Further, the wiring opening 70a (see FIG. 9) formed on the front surface of the rear housing case 70 from the effect control board 71 and the right frame portion 63 of the panel housing member 51 (so as to face a connector 52a described later). A harness 78 that extends through the wiring opening 63a and extends toward the liquid crystal display device 50 is used for signal supply for supplying a signal for displaying an image on the liquid crystal display panel 52. A connector 79 is provided at the end of the harness. The connector 79 is detachable from a connector 52a (see FIG. 8) provided on the rear edge side of the liquid crystal display panel 52 and at the right edge and electrically connected to the liquid crystal display panel 52. The connector 79 is attached to the connector 52a. The panel storage member 51 is put on the sheet metal 55 in a state of being connected to.

  Of the left and right frame portions 63, 63, the left frame portion 63 protrudes rearward on the rear surface side of the panel storage member 51, and the front side is recessed rearward by the amount of the protrusion, and the inverter board is in the recessed space. 83 is housed. From the upper and lower ends of the inverter board 82, harnesses 83 for power supply to the liquid crystal display panel 52 are extended, and the harness 83 for power supply is routed to the left end of the liquid crystal display panel 52. It is connected to make the length as short as possible.

  The reason for setting the routing length of the power supply harness 83 short is as follows. In order to drive the liquid crystal portion of the liquid crystal display panel 52 with alternating current to emit the backlight, it is necessary to supply a high current from the inverter substrate 82 toward the liquid crystal display panel 52. However, if the length of the power supply harness 83 connecting the inverter board 82 and the liquid crystal display panel 52 is set to be long, there is a risk of electric shock due to electric leakage or the like, or high-frequency noise generated from the power supply harness 83 is caused by the game board. There is a concern that malfunction may occur due to entering the control board or the like inside the main board assembly 30 disposed on the back surface of the board 10. For this reason, it is desirable to set the routing length of the power supply harness 83 as short as possible.

  From such a request, the routing length of the signal supply harness 78 is set longer than the routing length of the power supply harness 83 in consideration of the formation position of the wiring opening 63a and the mounting position of the inverter board 82, With the power supply harness 83 connected to the liquid crystal display panel 52 and the inverter board 82, the connector 79 provided on the harness 78 is removed from the connector 52a on the liquid crystal display device 50 side, as shown in FIG. The panel storage member 51 is removed from the liquid crystal display device 50 and the liquid crystal display panel 52 is replaced. The power supply harness 83 is connected to the liquid crystal display panel 52 and the inverter board 82, and the connector 79 is connected to the connector 52a to attach the liquid crystal display panel 52 to the panel storage member 51. Yes. Here, when the length of the signal supply harness 78 is increased with a margin so that the operator can easily work when the connector 79 and the connector 52a are attached and detached, the panel storage member 51 is placed over the connector 79 and the connector 52a. , The harness 78 becomes too long and an extra portion is generated and cannot be accommodated in the panel storage member 51, so that the panel storage member 51 may be difficult to cover the liquid crystal display panel 52 side.

  For this reason, the frame portion 63 formed to protrude rearward on the rear surface side of the panel storage member 51 has a front surface side recessed toward the rear by the amount of the protrusion, and the harness 78 is stored from the front side of the panel storage member 51. A harness housing portion 65 that is a space that can be made to extend in a groove shape is formed. According to such a configuration, when the connector 79 on the harness 78 side and the connector 52a on the liquid crystal display device 50 side are connected, the excess portion of the harness 78 is accommodated in the harness accommodating portion 65 so as to escape. Thus, it is possible to reliably cover the panel storage member 51 on the liquid crystal display panel 52 side.

  The front housing cover 60 covers the heat sink 64 and the liquid crystal control board 61 installed behind the heat sink 64 from the rear side when the panel housing member 51 is put on the liquid crystal display panel 52 (see FIG. 8). When the panel storage member 51 is covered so as to cover the sheet metal 55 from the state shown in the drawing, the flange portions 67 and 67 formed on the upper and lower sides of the front storage cover 60 are bonded to the front surface of the upper flange portion 67. Further, a cushion 68 made of a strip-like elastic conductive material abuts against the sheet metal 55 (the panel storage member 51 is cut out so as to abut on the sheet metal 55), and the liquid crystal display panel 52 side It is possible to ground from. As the conductive material having elasticity, for example, a material in which a metal foil made of a laminate of copper plating and nickel plating in a striped or mesh shape is provided on the surface of an elastic material such as urethane sponge is preferable.

  As shown in FIG. 6, the rear housing case 70 includes a receiving member 72 that receives the effect control board 71 on the front surface of the effect control board 71, and a lid member 73 that covers the receiving member 72 and is fixed to the receiving member 72. It consists of two members consisting of The lid member 73 is formed with a harness receiving portion 75 having a substantially rectangular shape in a rear view that is recessed forward and extending right and left so as to cut out the right side surface of the lid member 73. A harness connected to the production control board 71 via the connector 71a (see FIG. 5) and connected to the main board assembly 30 is received by the harness receiving portion 75, so that the harness protrudes behind the image control board assembly 40. Can not be. The material of the rear housing case 70 is formed by molding a transparent resin made of acrylic or the like into a predetermined shape.

  As shown in FIG. 9, the lower end portion of the receiving member 72 of the rear housing case 70 on the front side extends in a substantially L shape projecting from the rear surfaces of the frame portions 63 and 63 surrounding the front housing cover 60. Engaging portions 76, 76 that can engage with the engaging portions 69, 69 are formed to project in a substantially L shape (in FIG. 9, only the right engaging portion 76 is shown on the right and left sides). The receiving member 72 can be fixed to the frame parts 63 and 63 by screwing the receiving member 72 to the frame parts 63 and 63 while being engaged with the locking part 69. Further, the lid member 73 is received by the four screws 77, 77,... (See FIG. 5) by covering the lid member 73 with the receiving member 72 in a state where the effect control board 71 is received, so that the lid member 73 receives the lid. The effect control board 71 mounted on the member 72 is housed in the rear housing case 70. Along with screwing the lid member 73 to the receiving member 72, the rear surface of the front housing cover 60 is pushed toward the sheet metal 55 by the front surface of the receiving member 72, and is adhered to the front surface side of the flange portion 67 of the front housing cover 60 in a strip shape. The cushion 68 is pressed against the sheet metal 55.

  With the image control board assembly 40 attached to the back side of the game board 10, the upper surface of the lid member 73 of the rear housing case 70 extends to the liquid crystal display device 50 side (see FIG. 4), and the exhaust port 74 is in the rear stage. It is provided at a substantially central portion on the upper surface of the lid member 73 of the housing case 70. The exhaust port 74 is provided so as to be positioned just above the cooling fan 72. When the cooling fan 72 is operated, the air in the front housing cover 60 is exhausted to the outside through the exhaust port 74. . The hole shape constituting the exhaust port 74 is, for example, an aggregate of circular holes having a diameter of about 2 to 3 mm, and the hole diameter is reduced to prevent illegal acts on the liquid crystal control board 61 in the board housing case 60. I have to. Further, the hole shape is not limited to a circular hole, and may be, for example, a slit-shaped hole.

  When the rear housing case 70 is attached to the rear of the front housing cover 60 as described above, the outside air is surrounded by the left and right frame parts 63, 63, the rear surface of the panel housing member 51, and the front surface of the rear housing case 70. An air intake space 81 to be introduced into the housing cover 60 is formed (see FIG. 6). The air intake space 81 is formed so as to face the cooling fan 62 with the front housing cover 60 interposed therebetween, and the air flows in the vertical direction of the front housing cover 60 by the operation of the cooling fan 62. Under such a configuration, the hot air generated in the front housing cover 60 by the liquid crystal control board 61 which is a heat generation source is forcibly exhausted from the exhaust port 74 to the outside by the operation of the cooling fan 62 described above, and the air intake From the entrance space 81, new air is introduced into the front housing cover 60. For this reason, heat dissipation to the outside can be promoted, and the temperature in the front housing cover 60 can be maintained at an appropriate temperature. In this manner, it is possible to prevent hot air from remaining in the front housing cover 60 due to heat generation from a heat generation source such as an electronic device component such as a CPU on the liquid crystal control board 61.

  Further, the air intake space 81 can be used when the image control board assembly 40 removed from the game board 10 is carried, and a hand is inserted into the air intake space 81 (in the direction of the front housing cover 60). Then, the image control board assembly 40 can be easily carried with one hand. In the conventional image control board assembly, the handle for carrying it is provided so as to protrude left and right on the left and right side surfaces of the image control board assembly. However, like the image control board assembly 40 according to the present invention, the image control board assembly has a handle. When the size of the control board assembly 40 is increased, it is difficult to provide a handle so as to protrude to the left and right of the image control board assembly due to the storage space of the game board 10. Therefore, in the present invention, the air intake space 81 is used when the image control board assembly 40 is carried, so that the size of the image control board assembly 40 can be increased.

  As shown in FIG. 6, the harness extends to the left and right at the lower edge of the rear surface of the liquid crystal display device 50, that is, below the left and right frame parts 63 and 63 and the air intake space 81. A harness installation space 57 that can be routed is formed. On the other hand, as shown in FIG. 4, the rear surface of the liquid crystal display device 50 and also on the upper edge, that is, above the lid member 73 of the rear housing case 70 (above the exhaust port 74) A harness installation space 57 is formed extending in the direction. For this reason, the harness pulled out from the effect control board 71 to the harness receiving portion 75 formed in the lid member 73 of the rear housing case 70 can be extended toward the main board assembly 30 after being routed to the harness installation space 57. This is possible, and the rear side of the enlarged liquid crystal display device 50 can be effectively used as a harness installation location.

  In addition, on the rear surface of the panel storage member 51, a plurality of harness holding portions 58 extending integrally from the rear surface of the panel storage member 51 in a substantially L shape are provided side by side with the harness installation space 57. When a harness extending from the effect control board 71 side is routed to the harness installation space 57, the harness is hooked on the harness holding portion 58. In addition, as shown in FIG. 6, the harness holding portions 58 extending upward in an L shape and the harness holding portions 58 extending downward in an inverted L shape are alternately attached to the rear surface of the panel storage member 51. Thus, the harness is firmly held by the harness holding portion 58 without dropping from the harness holding portion 58. The harness holding portions 58 may be detachable from the receiving surface. The harness holding portions 58 attached to the panel storage member 51 may be attached according to the type of harness, the type of the liquid crystal display panel 53 in which the harness extends, and the like. The number and direction may be changed as appropriate.

  Here, the effects achieved in the present invention are summarized as follows. That is, in the gaming machine according to the present invention, the liquid crystal display device includes a liquid crystal display panel and a panel storage member that stores the liquid crystal display panel. The liquid crystal control device (liquid crystal control substrate) for controlling the display is not provided in the liquid crystal display device, and the liquid crystal control device is provided separately from the liquid crystal display device. For this reason, when replacing the liquid crystal display panel as in the prior art, it is not necessary to perform troublesome work such as removing the liquid crystal display panel from the liquid crystal control board, and the liquid crystal display panel can be easily replaced. When removing the liquid crystal display panel from the liquid crystal display device, after removing the image display device from the game board, a panel frame member that fits the liquid crystal display panel from the front side of the liquid crystal display panel to the panel storage member is provided. If it is removed from the panel storage member, the liquid crystal display panel can be easily taken out of the panel storage member and replaced. That is, when the liquid crystal display panel is replaced, the liquid crystal display panel may be removed from the front surface side, and the replacement work of the liquid crystal display panel that has been enlarged in recent years can be easily performed.

  In the gaming machine according to the present invention, a protection panel provided to be overlapped on the front side of the liquid crystal display panel in order to protect the liquid crystal display panel is fitted to the panel housing member together with the liquid crystal display panel by the panel frame member. Thus, in the gaming machine according to the present invention, unlike the conventional case, the protective panel is not adhered to the front surface of the liquid crystal display panel with a double-sided tape or the like. When it is necessary to replace the panel, the troublesome work of peeling the adhesive surface is not required, and the protection panel can be easily replaced.
