Among these, the inclined bottom portion 117 is connected to the wind guide plate 141A of the middle case 120, and is a wind guide plate 141B that guides the cooling air toward the exhaust port 126 together with the wind guide plates 141 and 141A.
Here, the storage space 14 for storing the image processing board 101 and the mounting space 11 for mounting the sub-control board 93 are juxtaposed on the left and right sides of the middle case 120, and the boundary between the storage space 14 and the mounting space 11. The cooling fan 133 is provided in the vicinity of the side wall 124 disposed in the part, the opening 125 corresponding to the outlet 133B of the cooling fan 133 is provided in the side wall 124, and the opening 125 of the side wall 12A provided in the rear case 12 The opposing part is recessed, and this recess is used as an exhaust passage for cooling air, and the rear case 12 also serves as an exhaust duct.

Thereby, even if the exhaust port 126 for exhausting the cooling air is provided on the back surface 120A of the entire case, there is no need to separately provide an exhaust duct for guiding the cooling air to the exhaust port 126, and the structure of the entire case is simplified. It is like that.
According to this embodiment as described above, the following effects can be obtained.
That is, the position of the air inlet 123 is set on the side surface of the side wall 121 of the middle case 120, the position of the air inlet 114 is set on the side surface of the side wall 113 of the liquid crystal rear case 111A, and the rear surface 120A of the entire case is placed. Since the position of the exhaust port 126 is set, conductive dust may enter the liquid crystal rear case 111A and the middle case 120 of the special symbol display device 28 through the intake ports 114 and 123 and the exhaust port 126. In addition, the short circuit of the electronic circuit provided on the image processing substrate 101 due to these dusts is prevented, and the possibility that the special symbol display device 28 may be broken can be eliminated.

In addition, since both the heat sink 131 and the cooling fan 133 are fixed to the bracket 132, the heat sink 131 and the cooling fan 133 are disposed in close proximity, and the heat sink 131 is brought into contact with the LSIs 101A and 101B. The heat transfer effect and heat dissipation effect of the unit 130 can be improved. Further, by providing the exhaust port 126 on the back surface 120A of the entire case, the distance from the intake ports 114 and 123 provided on the side surfaces of the side walls 113 and 121 to the exhaust port 126 is shortened. Can be reduced.
As described above, the heat transfer effect and heat dissipation effect of the air cooling unit 130 can be improved, and the flow resistance of the cooling air can be reduced. Therefore, even if the convection phenomenon cannot be used, it is good. Cooling efficiency can be ensured, and the cooling fan 133 can be sufficiently downsized.

  Further, since the air inlets 114 and 123 are provided on the side surfaces of the side walls 113 and 121, entry of dust from the air inlets 114 and 123 into the liquid crystal rear case 111A and the middle case 120 can be suppressed. The short circuit of the electronic circuit can be prevented, and even if the heated air rises below the liquid crystal rear case 111A and the middle case 120, it rises unlike the case where the intake ports 114 and 123 are provided on the lower surface. Therefore, even if another heat generating device such as another LSI or an electric motor is arranged below the liquid crystal rear case 111A and the middle case 120, the influence of the heat generating device is not affected. It can be avoided.

Further, by arranging the suction port 133A of the cooling fan 133 so as to face the side surfaces of the side walls 113, 121 provided with the suction ports 114, 123, the suction port 133A of the cooling fan 133, the liquid crystal rear case 111A, and Since the air inlets 114 and 123 of the middle case 120 are disposed to face each other, the cooling air flows linearly inside the liquid crystal rear case 111A and the middle case 120. From this point also, the circulation of the cooling air Resistance is reduced and good cooling efficiency can be ensured.
Further, even if the blowing direction of the cooling air blown from the blower outlet 133B of the cooling fan 133 intersects with the discharge direction of the exhaust through the exhaust outlet 126, the exhaust of the case back surface 120A is located in the vicinity of the blower outlet 133B of the cooling fan 133. Since the air guide plates 141, 141A, 141B for guiding the cooling air toward the port 126 are provided facing the air outlet 133B, the exhaust efficiency from the exhaust port 133B is not impaired, and also from this point, A sufficient amount of cooling air is secured, and good cooling efficiency can be secured.

In addition, since the exhaust port 126 and the intake ports 114 and 123 are formed by holes of a size in which the game ball cannot enter the inside, the conductive game ball passes through the exhaust port 126 or the intake ports 114 and 123 and is specially provided. The liquid crystal rear case 111A and the middle case 120 of the symbol display device 28 do not enter the inside, the electronic circuit of the image processing board 101 is prevented from being damaged or short-circuited by the game ball, and the special symbol display device 28 may be damaged. Can be resolved.
Furthermore, even if the individual holes are small, if the quantity is set sufficiently large, the air volume of the cooling air can be secured sufficiently, so that the size of each hole of the intake ports 114 and 123 is made small so that the game ball cannot pass. However, good cooling efficiency can be ensured.

Similarly, even if the width of the hole is small, if the length is set sufficiently long, the air volume of the cooling air can be sufficiently secured. Therefore, the hole size of the exhaust port 126 is made small so that the game ball cannot pass. Also, good cooling efficiency can be ensured.
Further, since the bracket 132 is made of aluminum having good thermal conductivity, the heat generated in the LSIs 101A and 101B is also dissipated through the bracket 132, which is considered to improve the cooling efficiency of the cooling fan 133. Thus, the cooling capacity of the LSIs 101A and 101B can be improved.
