Even if the second sealing fitting 90 is engaged and pulled out from the rectangular hole S2, it can no longer be pulled out. Thereby, the irreversible sealing of the main control board case 30 is completed. The situation at this time is shown in FIGS. 10 is a plan view of the main control board case 30 in a sealed state, and FIG. 11 is a cross-sectional view taken along the line AA of FIG.

  Next, a procedure for opening the main control board case 30 in a sealed state when inspecting the main control board will be described. First, as shown in FIG. 11, three cutout portions provided around the second sealed portion 81 among the first sealed portion 51 and the second sealed portion 81 that are currently sealed. Cut out 85, 85, 85 with nippers or scissors. When these cut-out portions 85 are cut with a nipper, the cutting force is applied by compression, and when cut with scissors, the cutting force is applied with shear and cut. Since each cut-out portion 85 is made of a highly viscous ABS resin, its cut surface is plastically deformed into a crushed shape and whitened at the same time. After the cut portion 85 is cut in this way, the first sealed portion 51 and the second sealed portion 81 that are in the sealed state are maintained in the sealed state as they are. Since the periphery of the stop portion 81 is cut, the second sealed portion 81 can be separated from the second mounting member 80, and as a result, the case lid body 70 slides in a direction away from the case body 40. It becomes possible. Therefore, if the case lid 70 is slid from the case main body 40 in the detaching direction, the main control board case 30 can be opened, and the main control board accommodated therein can be inspected. At the time of this inspection, the date on which the main control board was inspected is entered in the history sticker pasted on the sticker application location 71b. By leaving the inspection history in this way, if the main control board case 30 has not been opened due to fraud, the number of the second sealed portions 81 from which the cutout portion 85 is cut matches the number of inspections. On the other hand, if the number of the second sealed parts 81 from which the cut-out part 85 is cut is larger than the number of inspections, it means that it has been opened other than the inspection, and there is a high possibility that a malicious person has performed an illegal act. It can be said. In order to re-seal, the first sealed portion 51 and the first sealed portion different from the first sealed portion 51 in a state where the main control board is accommodated in the accommodating space formed by the case body 40 and the case lid 70. The second sealed portion 81 aligned with the stopper 51 is irreversibly sealed by the first and second sealing fittings 60 and 90.

  According to the embodiment described in detail above, the cutout portion 85 is formed of ABS resin that leaves a visible trace when a cutting force due to compression / shearing is applied. Even if it is cut and opened and attached with an adhesive or the like, a visible trace remains in the cut portion 85 after cutting, so that it can be easily recognized in appearance that the sealing has been broken. For this reason, since it turns out that the trace remains when a malicious person cut | disconnects the 1st of the three cut-out parts 85 illegally, it is expected to give up fraud. Further, it is possible to easily recognize that there has been an illegal act by comparing the history of the number of inspections with the number of traces.

  In addition, after all of the plurality of first sealed portions 51, 51,... Of the first mounting member 50 and the plurality of second sealed portions 81, 81,. The first attachment member 50 is detached from the case body 40 and the second attachment member 80 is detached from the case lid body 70 in a state where the body 70 is slid and removed in the direction away from the case body 40 and the main control board is removed. The main control board case 30 can be regenerated by reattaching the new first and second mounting members 50 and 80 to the case body 40 and the case lid 70, respectively.

  Further, since the second mounting member 80 is made of colored ABS resin, the color of the main control board case 30 can be determined in accordance with the model of the pachinko machine 20, so that the model of the pachinko machine 20 The correspondence with the main control board can be easily recognized.

  Furthermore, the first sealing member 60 and the second sealing member 90 are used to connect the predetermined first sealed portion 51 of the first mounting member 50 and the first sealed portion 51 of the second mounting member 80. In a state where the matching second sealed portion 81 is sealed, the first mounting member 50 is prevented from moving in the direction of detachment from the case body 40 by the flange tip 73b of the case lid body 70, 2 Since the attachment member 80 is prevented from moving in the direction away from the case lid 70 by the main control board, the case body 40, the first attachment member 50, the case lid 70, the second attachment in the sealed state. The member 80 cannot be disassembled.

  The first mounting member 50 and the case main body 40, the second mounting member 80 and the case lid 70, and the case main body 40 and the case lid 70 can be attached and detached by a slide mechanism without bonding and screwing, respectively. Since they are fitted together, when the main control board case 30 is regenerated, an operation of removing the bonding and screwing becomes unnecessary, and disassembly and assembly are facilitated.

  In addition, the first sealing fitting 60 and the second sealing fitting 90 are employed as the sealing members, and the first sealing fitting 60 before being disposed at a position aligned with the second sealed portion 81 is used. The second sealing fitting 90 is inserted into the slit S1 of the first sealing portion 51 so as not to be detached, and the first sealing portion 51 and the second sealing portion 81 into which the first sealing fitting 60 is inserted. In order to engage with the first sealing fitting 60 in a state where it is hooked on the bridging portion 83 of the second sealed portion 81 by being inserted into the rectangular hole S2 of the second sealed portion 81 in a state of being aligned, Once sealed, these seals cannot be unwound, and the cut-out portion 85 is cut to unlock the seal. Therefore, the effect of the present invention is effectively exhibited.

  The embodiment of the present invention is not limited to the above-described embodiment, and it goes without saying that various forms can be adopted as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the main control board case is shown as an example of the board case of the gaming machine of the present invention. However, a board case other than the main control board, for example, a payout control board case that houses a payout control board, display control A display control board case for housing a board, a lamp control board case for housing a lamp control board, a voice control board case for housing a voice control board, or the like may be exemplified. In these cases, the same effect as the above-described embodiment can be obtained.

  Further, in the above-described embodiment, the cutout portion 85 is made of ABS resin, but may be made of resin having a viscosity equivalent to ABS (for example, styrene resin or AS resin). In this case as well as the ABS resin, the cut portion 85 after cutting becomes a crushed shape or whitens, so that it can be easily recognized in appearance that the seal has been broken. Further, the cutout portion 85 may be made of acrylic resin or PET resin. In this way, even if the cut-out portion 85 is cut and opened and then attached by an adhesive or the like, the cut-out portion 85 after the cut has cracks due to brittle fracture, so the seal is broken. This can be easily recognized in appearance.

  Furthermore, in the above-described embodiment, the first mounting member 50 can be attached to and detached from the case main body 40, but both may be integrally formed. Further, although the second mounting member 80 can be attached to and detached from the case lid 70, both may be integrally formed.

  Furthermore, in the above-described embodiment, the pachinko machine 20 has been described as an example. However, a gaming machine to which the present invention can be applied is not limited to a pachinko machine, and a determination is made as a game ball enters. Of course, the present invention can also be applied to all gaming machines, for example, gaming machines in which a pachinko machine and a slot machine are combined. As an example of the basic configuration of a gaming machine that fuses this pachinko machine and slot machine, a symbol string consisting of a plurality of symbols for identifying the gaming state according to the gaming state is variably displayed and then the symbol is fixedly displayed. Display means to start, the fluctuation of the symbol is started due to the operation of the start operation hand throw (for example, the operation lever), and the predetermined time has elapsed due to the operation of the stop operation means (for example, the stop button) Special game state generating means for generating a special game state advantageous to the player on the condition that the change of the symbol is stopped and the confirmed symbol at the time of the stop is a specific symbol, and a game ball is used as a game medium A game that is configured to be used and requires a predetermined number of game balls at the start of symbol variation, and that many game balls are paid out when a special game state occurs. It can be mentioned. Such gaming machines have a special gaming state (a big hit state) that is advantageous to a player who can acquire at least a large number of gaming balls, and a normal gaming state that is disadvantageous to a player who consumes the gaming balls. It can also be present. Alternatively, it can be applied to a slot machine.
