  As described above, the power supply board 660 supplies power to each device arranged in the slot machine 100. Specifically, the AC voltage supplied from the outside of the slot machine 100 by the power cord is converted into a DC voltage. In addition, the voltage is converted into a voltage required by each device. When the heat generated during the conversion work exceeds a certain temperature, the power supply board 660 cannot perform the conversion work normally, and it is necessary to release the heat from the power supply board 660.

  Also, in recent game machines, when changing the lottery value used for the lottery set for each game machine (so-called setting change), it is necessary to turn off the power once and turn it on again. was there. In addition, in order to give benefits to players who have come to the store immediately after opening, which is assumed to be normally powered on, there is a function to set the gaming state immediately after the power is turned on to a state advantageous to the player. There was a playground to have. There are those who perform an act (so-called goto act) that unreasonably gains profits by forcibly starting up and shutting down a power supply with such a set.

  What is generally known as a goto action is to force the power supply to shut down and start by forcing a foreign object (for example, a bite) into the gap from outside the game stand and forcibly shorting the power supply board. In addition, the power supply was turned off and on by operating a switch provided on the power supply board.

  In addition, there is a problem that the noise generated when the conversion work by the power supply board is performed affects other devices through the harness and the like, causing the game machine to malfunction. As a countermeasure, the power supply board is made of conductive sheet metal or the like. It was common to cover and connect the sheet metal to the ground so that the noise generated on the power supply board was released to the outside of the game table before affecting other devices.

  In the present embodiment, fraudulent acts are suppressed against this background, and the power board is effectively exhausted.

  The power supply unit case 600 is a case body composed of a base portion 601 and a lid portion 302 made of resin, and covers a power supply unit 620 composed of a power supply board 660 and a storage body 640 disposed so as to cover the power supply board 660.

However, in this embodiment, the arrangement position is shifted between the opening of the lid 602, that is, the exhaust port 604 and the intake ports 603, 605, and 606, and the opening of the housing 640, that is, the vent holes 641, 642, and 643. For example, in the vent hole 642 shown in FIG. 6B, the vent hole 642 is provided at a position sufficiently away from the intake port 605 provided below. For this reason, in the present embodiment, it is almost impossible for a foreign object to pass through the opening of the lid 602 and further pass through the opening of the storage body 640.

  Further, if the power supply unit case 600 is colored so that the inside cannot be seen through, the fraudster cannot see the inside of the power supply unit case 600 and knows the position of the opening of the housing 640. Because it is not possible, it is difficult to cheat.

  Further, in the present embodiment, since the high temperature air is light and rises, the high temperature air is discharged from the exhaust port 604 provided above, and the air is taken in from the intake ports 603, 605 and 606, and the lid 602. 6B in the exhaust heat flow paths 607, 608 and 609 between the storage body 640 and the exhaust heat flow path 610 in the storage body 640 passing through the vent holes 641, 642 and 643 of the storage body 640. An air flow as indicated by an arrow is generated, and the exhaust heat effect is enhanced. The heat generated by the power supply substrate 660 is exhausted by the exhaust heat channel 610. Further, since the housing 640 is provided with a plurality of vent holes 641, 642, and 643, a plurality of exhaust heat flow paths 610 through which air can pass can be provided, and efficient exhaust heat can be performed. Here, the exhaust heat flow path refers to a path through which air taken in from the intake port passes until reaching the exhaust port.

  In the present embodiment, only one exhaust port is provided as the exhaust port 604, but the present invention is not limited to this, and a plurality of exhaust ports may be provided.

(Second embodiment)
<Another example of storage>
FIG. 8 is an example different from the example shown in FIG. 6 of the storage body that is a shield sheet metal that covers the power supply board 660 and prevents noise generated by the power supply board 660, and the storage body has no opening. FIG. 6A is a side sectional view corresponding to FIG. 6B of this other example, and FIG. 6B is a side sectional view corresponding to FIG. 6C of this other example. It is. 8, since it is the same structure as FIG. 6 except a storage body, the same reference number is attached | subjected and detailed description is abbreviate | omitted. The dashed arrows shown in FIGS. 8A and 8B indicate the flow of air in the power supply unit case 600. 6A and 6B, illustration of electronic components mounted on the power supply board 660 is omitted.

  In the example of FIG. 8, a storage body 1640 is used instead of the storage body 640 shown in FIG.

  The storage body 1640 of this embodiment is formed of a shield metal plate, absorbs noise generated by the power supply board 660 by accommodating the power supply board 660 therein, and escapes from the ground, so It functions to prevent malfunction of the device.

  Further, unlike the storage body 640 of FIG. 6, the storage body 1640 of this embodiment does not have an opening in the shield sheet metal. For this reason, the operation of forming the opening is unnecessary, and the operation can be further shortened and the cost can be reduced. In addition, since the storage body 1640 does not have an opening and the power supply board 660 is completely covered with the storage body 1640, it is possible to reliably prevent the gore action itself of bringing a foreign object into contact with the power supply board 660.

  Further, since the shield sheet metal of the storage body 1640 is metal, it has a high thermal conductivity. Therefore, it is discharged by the gap between the power supply unit case 600 and the power supply unit 600, that is, between the lid 602 and the storage body 1640 in FIG. If the heat flow paths 1607, 1608, and 1609 are formed, the air taken in from the intake ports 603, 605, and 606 takes heat from the storage body 1640 when passing through the exhaust heat flow paths 1607, 1608, and 1609. Thus, the heat of the power supply board 660 can be discharged to the outside.

  As shown in FIG. 8, exhaust heat flow paths 1607, 1608, and 1609 are formed by the storage body 1640 that covers the power supply substrate 660 and the power supply unit case 600 that covers these, and slots are formed in the exhaust heat flow paths 1607, 1608, and 1609. By letting air from the outside of the machine 100 pass through, the heat generated by the power supply board 660 can be discharged to the outside of the slot machine 100, and the power supply board 660 is completely covered with the housing 1640. Therefore, since it is possible to prevent fraud, it is possible to provide the slot machine 100 that allows the player to play the game with peace of mind.

  In the present embodiment, since the exhaust port 604 is provided above the intake ports 603, 605, and 606, the air inside the power supply unit case 600 is directed to the exhaust port 604 due to the property of rising hot air. The exhaust heat effect can be enhanced without staying in the power supply unit case 600.

(Third embodiment)
<Another example of the power supply unit case cover and storage body>
FIG. 9 is a view showing an example using a power unit case cover and a storage body, which is different from the examples shown in FIGS. 6 and 8, and FIG. (B) is an enlarged perspective view showing the periphery of the exhaust port in the back plate 242 in a state in which the power supply unit case is assembled to the housing 101. 9, since it is the same structure as FIG. 6 except a power supply unit case cover part and a storage body, the same reference number is attached | subjected and detailed description is abbreviate | omitted. The broken-line arrows shown in FIG. 9A indicate the flow of air in the power supply unit case. In FIG. 9A, illustration of electronic components mounted on the power supply board 660 is omitted.

  In the example of FIG. 9, the lid portion 2602 and the storage body 2640 of the power supply unit case 600 are used instead of the lid portion 602 and the storage body 640 of the power supply unit case 600 shown in FIG. 6.

  The storage body 2640 of the present embodiment is formed of a shield metal plate, absorbs noise generated by the power supply board 660 by accommodating the power supply board 660 therein, and escapes from the ground, so It functions to prevent malfunction of the device. Further, the storage body 2640 has a plurality of openings such as vent holes 2641 and 2643.

  The lid portion 2602 of the power supply unit case 600 in the present embodiment further utilizes the characteristic that it rises when the air is warmed, so that the surface constituting the ceiling portion 2602b of the lid portion 2602 leading to the exhaust port 2604 faces the exhaust port 2604. The ceiling is gradually raised.

  Further, since air tends to stay in the corner, the lid portion 2602 of the present embodiment is provided with a curved inner surface of the corner portion 2602a. As a result, the air passing through the exhaust heat flow path formed between the intake port 2603 and the exhaust port 2604 can pass through the power supply unit 620 and the power supply unit case 600 more smoothly.

  In addition, the present embodiment is also characterized by the shape of the shield metal plate made of conductive metal plate that forms the storage body 2640 that covers the power supply substrate 660. In the example shown in FIG. 6, in order to prevent an illegal act from the opening of the intake port 604 and the exhaust port 603 to the power supply board 660, for example, the arrangement position is shifted in a staggered manner or an angle is given from the opening. Intrusion of foreign matter was prevented, but in this embodiment, in order to make entry of foreign matter more difficult, a part of the opening (vent hole 2641) formed in the shield metal plate was hidden and overlapped with the shield metal plate. Furthermore, the inclined surface provided to overlap the sheet metal faces in the direction of the opening (exhaust port 2604), that is, the opening of the vent hole 2641 faces to the side of the opening (exhaust port 2604) where foreign matter is easily inserted. Since the configuration is such that there is no foreign matter, it is possible to make it more difficult for foreign matter to enter the power supply substrate 660. Even if the shield metal plate that covers the power supply substrate 660 is configured in such a shape, the cover portion 2602 of the power supply unit case 600 forms the exhaust heat flow path, so that the air flows smoothly in the exhaust heat flow path, The heat of the power supply board 660 can be discharged to the outside.

  In order to prevent foreign matter entering from the air inlet and exhaust port from coming into contact with the power supply board provided inside the housing, the air vent provided in the housing should be provided at a position away from the air inlet and exhaust port. In addition, the vent can be provided at an angle in a direction opposite to the intake and exhaust ports, or can be formed so as to cover the opening of the storage body as shown in FIG.
