Measures are taken.

(Effects of Example)
Next, the operation of the pachinko machine according to the above-described embodiment will be described.

  When assembling the board case 20, the first connector 23 provided on the control board 22 and the second connector 26 provided on the connector board 25 are connected via a harness 28. In this state, the corresponding third connector 27 of the connector board 25 is inserted through each opening 32a of the protective wall 32 to be exposed to the front (outside of the cover member 30), and formed on both the boards 22 and 25. The control board 22 and the connector board 25 are fixed to the opening side of the cover member 30 by screwing the screws 36 inserted through the through holes 22c and 25c into the corresponding screw holes in the cover member 30, respectively.

  Next, the engagement pieces 34, 34 of the cover member 30 to which the control board 22 and the connector board 25 are fixed are inserted into the corresponding slits 40, 40 of the base member 38, and the opening of the cover member 30 and the base It rotates and closes so that the opening of the member 38 is aligned. And each 2nd connection part 46 formed in the lower wall 38c of the said base member 38 and each 1st connection part 35 formed in the lower wall 31c of the cover member 30 are aligned, respectively, and the left side of the cover member 30 and Any one of the four first connecting portions 35 aligned on the right side is screwed to the corresponding second connecting portion 46 via a screw 49, whereby the base member 38, the cover member 30, Is fixed inseparably. Further, by fitting the cap piece 48 to the first connecting portion 35 fixed by the screw 49, the loosening operation of the screw 49 by a tool cannot be performed, and unauthorized opening of the cover member 30 can be prevented.

  Here, in the embodiment, when the cover member 30 and the base member 38 are assembled, the control board 22 to which the control component 22a is attached is completely accommodated (sealed) in the accommodation space 21 and controlled. Since the substrate 22 is configured not to be exposed to the outside of the case, it is possible to reliably prevent an illegal act with respect to the control substrate 22. By the way, in order to perform a required game effect with the pachinko machine 10, it is necessary to electrically connect the sub-control device 18, a ball detection sensor, and the like located outside the substrate case 20 to the control substrate 22. Therefore, in the embodiment, the connector board 25 is provided as a separate body from the control board 22, and the first piece 25a of the connector board 25 (the installation area of the second connector 26) is positioned in the accommodation space 21, The second piece 25b (installation region of the third connector 27) of the connector substrate 25 is configured to be partitioned by the upper side wall 31b of the cover member 30 (box-shaped portion 31) so as to be positioned outside the accommodation space 21.

  Accordingly, the first connector 23 of the control board 22 and the second connector 26 of the connector board 25 are electrically connected within the accommodation space 21, and the third connector 27 and the sub-control of the connector board 25 are outside the accommodation space 21. The control board 22 can be electrically connected to the sub-control device 18 and the ball detection sensor by connecting a harness connector from the device 18 and the ball detection sensor. That is, while the control board 22 is completely housed (sealed) in the housing space 21, a detection signal from the ball detection sensor can be transmitted to the control board 22, and the control signal from the control board 22 is sub-controlled. It can transmit to the apparatus 18 and a required game effect can be performed. Thus, in the main control device 17 according to the embodiment, even when the control board 22 is completely accommodated in the accommodation space 21, the sub-control device 18, a ball detection sensor, etc. via the connector board 25. And the control board 22 can be electrically connected to each other, and the upper side wall 31b of the cover member 30 (box-like portion 31) separating the connector board 25 is used to prevent foreign matter from entering the housing space 21. 22 can be prevented.

  Moreover, even when the connector board 25 is provided separately from the control board 22 as in the embodiment, the connector board 25 is attached to the board case 20 by attaching the connector board 25 to the board case 20. Can be handled integrally. That is, even when the connector board 25 is separately provided, the main control device 17 can be handled in the same manner as in the past. Also, with respect to the connection work between the main control device 17 and the sub control device 18, it is only necessary to connect to the third connector 27 provided on the substrate case 20 of the main control device 17 as in the prior art. It does not cause a decline in sex.

  Further, since the opening 32 a opened in the protective wall 32 is formed so as to substantially match the outer shape of the third connector 27, a gap generated between the protective wall 32 and the third connector 27 is formed. It can be made as small as possible, and foreign matter can be prevented from being inserted into the inside of the substrate case 20 (inside the accommodating space 21) through the opening 32a. Further, in the state where the connector board 25 is fixed to the cover member 30, the protective wall 32 is in close contact with the surface (second piece portion 25b) of the connector board 25, so that the connector board 25 can be protected, and It is possible to make it more difficult to insert a foreign substance into the storage space 21 and to reliably prevent an illegal act on the control board 22. Further, the partition wall 44 formed on the base member 38 allows the first piece 25a (the installation area of the second connector 26) and the second piece 25b (the installation area of the third connector 27) on the back surface of the connector board 25 to be formed. Therefore, even if foreign matter enters the back side of the connector board 25 through the opening 32a of the protective wall 32, the foreign matter is controlled by the partition wall 44. Since it is possible to prevent entry into the accommodation space 21 in which the substrate 22 is accommodated, there is no possibility that an illegal act is performed on the control substrate 22. Further, the partition wall 44 of the base member 38 is formed at a position aligned with the upper side wall 31b of the cover member 30 in the front-rear direction, and is in close contact with the back surface of the connector board 25. On the other hand, even if an external force is applied in the rear side direction, no gap is formed between the upper side wall 31b and the surface of the connector board 25 and the upper side wall 31b can be kept in good contact.

  Here, for example, when the cover member 30 is rotated and opened with respect to the base member 38 in a state where the connector substrate 25 is fixed to the base member 38, the protrusion of the third connector 27 from the connector substrate 25 is particularly important. In the case where the height is large or the plurality of third connectors 27 are arranged close to each other, the third connector 27 interferes with the edge of each opening 32a of the protective wall 32 moving in an arc shape, and the opening 32a. There is a risk that it cannot be inserted into the. In the embodiment, however, the connector board 25 is fixed to the cover member 30 in advance, and the cover member 30 is rotated and opened with respect to the base member 38 with the third connector 27 inserted through the opening 32a. Therefore, the third connector 27 does not interfere with the protective wall 32 when the cover member 30 is rotated and opened, and smooth opening and closing is achieved.

[Example of change]
Note that the gaming machine according to the present invention is not limited to the embodiment, and various modifications can be made. For example, the configuration for separating the installation area of the connector connected to the electrical component on the connector board and the installation area of the second connection portion connected to the control board is not limited to that of the embodiment, and any configuration is possible. Can be adopted. Specifically, as shown in FIG. 10, the cover member 60 may be formed with a regulating piece (image wall) 61 that contacts the edge of the connector board 25 on the control board 22 side. As shown, an image wall 64 that abuts against the rear end edge of the restricting piece 61 can be formed on the base member 63. Also in this case, the second connector 26 connected to the first connector 23 of the control board 22 is positioned in the accommodation space 21, and the third connector 27 connected to the sub-control device 18, the ball detection sensor or the like is located outside the accommodation space 21. Therefore, the same effect as the embodiment can be obtained. In addition, by providing the restriction piece 61 and the drawing wall 64, it is possible to more reliably prevent foreign matter from entering the accommodation space 21. In FIGS. 10 and 11, members having the same functions as those in the embodiment are denoted by the same reference numerals.

  Further, the shapes of the control board and the connector board are not limited to those of the embodiment, and can be arbitrarily determined. That is, the control board is formed in a size that can be accommodated in the accommodation space of the board case, and the first connection part is formed at an arbitrary position, and the connector board is connected to the first connection part. If it has the 2nd connection part and the connector connected to the electrical component outside a substrate case, the magnitude | size and shape can be set arbitrarily. In addition, if it is provided separately from the control board, it is also possible to provide a plurality of connector boards. In addition, the first and second connecting portions are not limited to the configuration of connecting via the harness as in the embodiment as long as they are configured to be electrically connected to each other, and conventionally known various configurations and members are adopted. Is possible.

  Further, with respect to the board case, the connector board is arranged so that the second connection part connected to the control board is located in the accommodation space defined inside, and the connector connected to various electrical components is located outside the accommodation space. What is necessary is just to form in the shape and magnitude | size which can be installed. Further, in the embodiment, the shielding portion having an opening substantially matching the outer shape of the connector in the connector substrate is formed integrally with the substrate case (cover member), but the shielding portion is the substrate case. Even if it is provided as a separate body, the same effect as the embodiment can be obtained. In addition, it is not restricted to the structure which provides a heat radiating hole in a cover member like an Example, and this heat radiating hole can also be abbreviate | omitted when improving a fraud prevention effect more. That is, by omitting the heat radiating hole, the control board can be completely sealed by the board case, so that the intrusion of foreign matters can be more reliably prevented to prevent illegal acts.

  In the embodiment, the configuration according to the present invention is adopted in the main control device that controls the entire pachinko machine. However, the present invention is not limited to this, and can be adopted in other control devices. Further, the configuration according to the present invention can be adopted not only in the control device provided in the pachinko machine as in the embodiment but also in the control device provided in the arrange ball machine, the slot machine machine, and other various game machines.
