Since the first space 152 is provided, static electricity or the like generated in the mechanism plate 53 is less likely to be transmitted to the circuit board housing case 110, and the second space 153 and the third space 15 are also included.
Since the capacity of the space is different from that of No. 4, the speed of warming of the air in the space is different, and the temperature difference causes the second space 153 and the third space 153 to differ.
Convection occurs so as to communicate with the space 154, and the heat generated by this convection can be effectively dissipated from the heat dissipation hole 121. Further, the above-mentioned circuit board 141 has shown that one set of the MUP 161, the ROM 162, and the RAM 163 constitutes the gaming device control circuit and the payout device control circuit.

Since 29 is inevitably damaged, it is determined whether or not the covering state of the first divided body 118 and the second divided body 132 covering the circuit board 141 has been released, as a sealing member.
It can be easily identified by looking at the state of 9. In addition, as the sealing member, a sealing paper 129, a part of which remains when opened, is used.
It is also possible to prevent a fraudulent act of loosening the screws 128a and 128b after the 9 is removed.

The following may be considered as modifications of the above embodiment. In the above-described embodiment, the one provided with two types of winning holes having different numbers of payout prize balls is shown, but the number of payout prize balls may be all the same or may be three or more. Further, the number of payout prize balls may be changed according to the game state. For example, the number of payout prize balls during the big hit control period may be increased compared to the normal time based on the fact that the variable display device 15 has become a predetermined display (big hit state). In the payout control of the gift ball, after the predetermined number of payouts is completed, a predetermined time interval may be set to start the next predetermined number of payouts, or the time interval may not be set.
The payout unprocessed ball counter may be continuously paid out until it reaches “0”. In this case, even if the number of payout prize balls is plural, the payout unprocessed ball counter may be configured by one common counter. When an abnormality occurs in the prize ball payout control, the game control may be interrupted and the game state at that time may be stored. The prize ball detector used for game control may also be used for the prize ball payout control. For example, in the above-described embodiment, if the starting winning prize detector 40a is also used for the prize prize payout control, the second winning prize detector 60 becomes unnecessary. Further, if the prize number detector 39 is also used for the prize ball payout control, it is possible to more effectively prevent fraud (withdrawal, shift, etc.) related to the prize number detector 39. If there is something wrong with the winning ball detectors 59, 60,
The prize balls collected by the prize ball collecting gutters 57 and 58 may be stored. Further, when the payout prize ball detector 96 is abnormal, the prize ball discharging passage may be switched so that the prize ball is not paid out to the player. In the above embodiment, the number of unprocessed payout balls, that is, the number of prize balls that have not been paid out is stored and displayed. However, instead of the number of prize balls, the number of prize balls is cumulatively added and the value is stored and displayed. You may allow it. The winning ball detector 5 is provided at the lower end of the winning ball detectors 59 and 60.
A stop device is provided for stopping the prize balls when 9, 60 is OFF, the prize ball detectors 59, 60 are turned ON, and the stop device is provided each time the payout operation of a predetermined number of prize balls is completed from the prize ball payout device. The winning balls stopped at may be discharged one by one. It may be a so-called arrange ball type pachinko gaming machine in which a score is generated based on a combination of winnings to a plurality of winning holes provided on a game board. In this case, the points given according to the establishment of the combination may be cumulatively added, stored, and displayed.

[0058]

As is apparent from the above description, in the present invention, in the circuit board housing case in which the circuit board is housed by the first and second divided bodies, the first and second divided bodies are provided. In order to separate the first divided body and the second divided body by sealing the upper surface of the fixing means for fixing the second divided body with the sealing member, the fixing means must be removed from the outside. However, for this reason, the sealing member will be damaged without fail. Therefore, by checking the state of the sealing member whether the covering state of the first divided body and the second divided body which cover the circuit board is released. You can easily tell.

Further, a screw is adopted as the fixing means,
In addition, the sealing member may be a sealing paper, a portion of which remains when the sealing member is opened, so that an unlawful act of loosening the screw after the sealing paper is peeled off can be prevented.
