Then, a pair of slits 85S and 85S are formed on both sides of each square protrusion 85 to separate both sides of the square protrusion 85 from the side wall 82 and the adjacent square protrusion 85, and the slits 85S and 85S are illustrated in FIG. In FIG. 5, the cut portions 85 </ b> T are formed in such a manner that a part of the side wall 82 can be ruptured by being brought close to each other at an upper portion of each square protrusion 85. And the sealing wall 80F is comprised from this square protrusion 85 and the cutting | disconnection part 85T, The sealing wall 80F is isolate | separated into plurality by the slit 85S mentioned above. In addition, the part except each upper end part of each slit 85S is shared between the adjacent rectangular protrusions 85 and 85. FIG.

  Each of the plurality of square protrusions 85 described above is disposed corresponding to the sealing pin through hole 71A of the opposed upright wall 71, and the square protrusion 85 is coaxially sealed with the sealing pin through hole 71A. A pin through hole 85A is formed through. As shown in FIG. 8, the inner diameter of the sealing pin through hole 85 </ b> A is reduced in a stepped shape in the middle in the axial direction, and the inner diameter on the opposed upright wall 71 side is reduced. Further, a sealing plug 64 or a sealing pin 65 (corresponding to a “sealing member” according to the present invention) can be inserted into the sealing pin through hole 85A.

  The sealing pin 65 has a structure including a head portion 65H at the base end portion and a locking groove 65M near the tip end. Then, the sealing pin 65 is inserted into the sealing pin through hole 85A from the distal end side, and the head portion 65H is locked to the step surface in the sealing pin through hole 85A. The sealing plug 64 has a structure in which a protrusion protrudes from the center of a disk having substantially the same diameter as the head portion 65H of the sealing pin 65. The sealing plug 64 is attached to the sealing pin through hole 85A in place of the sealing pin 65 in the sealing pin through hole 85A and closes the sealing pin through hole 85A.

  In addition, protective walls 84 and 84 are formed to protrude from the outer surface of the side wall 82 on both sides of the entire sealing wall 80F. The protective wall 84 protrudes from the side wall 82 with substantially the same protrusion amount as the square protrusion 85.

  The cover body 80 includes a plurality of substrate locking portions 83 according to the present invention on the inner surface of the substrate protection wall 81. Specifically, as shown in FIG. 6, the substrate locking portions 83 are respectively disposed at two positions on both sides of the inner surface of the substrate protection wall 81 with the sealing walls 80 </ b> F interposed therebetween, A total of four cover bodies 80 are provided. As shown in FIG. 8, each substrate locking portion 83 has a locking projection 83C and an auxiliary locking projection 83D at the tip of a flexible beam member 83K extending from the inner surface of the substrate protection wall 81 toward the bottom wall 67. I have. The locking projection 83C is located at the tip of the flexible beam member 83K with respect to the auxiliary locking projection 83D, and on the side of the board locking portion 83 facing the bottom wall 67 of the case body 66, the bottom wall 67 and A sliding contact slope 83 </ b> A that is inclined with respect to the facing direction of the substrate protection wall 81 is provided, and is orthogonal to the facing direction of the substrate protection wall 81 and the bottom wall 67 on the side facing away from the bottom wall 67. The locking surface 83B is provided. On the other hand, the auxiliary locking projection 83D is provided in the flexible beam member 83K at a position spaced substantially the same distance from the locking surface 83B as the main control board 60, and faces the locking surface 83B of the locking projection 83C. An auxiliary locking surface 83E is provided.

  Further, as shown in FIG. 7, between the pair of substrate locking portions 83, 83 arranged in the longitudinal direction of the cover body 80 (left and right direction in FIG. 7), both substrate locking portions 83 of the substrate protection wall 81 are provided. The lengths of the flexible beam members 83K and 83K are different depending on the height difference of the portion where the 83 and 83 are disposed, but the tip positions of the flexible beam members 83K and 83K of the board locking portions 83 and 83 are the same. Yes.

  The description regarding the structure which concerns on the pachinko gaming machine 10 of this embodiment is above. Next, the effect of the pachinko gaming machine 10 of this embodiment will be described. In the manufacturing process of the pachinko gaming machine 10, in order to accommodate the main control board 60 in the board housing case 62 and complete the main control device 50, the following may be performed. That is, the case body 66 and the cover body 80 are separated, and the case body 66 is placed with the substrate placement portion 66S facing upward.

  Then, as shown in FIG. 8, the main control board 60 on which electronic components such as the one-chip microcomputer 61A are mounted is mounted on the board mounting portion 66S with the electronic mounting surface 60J facing upward. Then, the small diameter portion 69A of the positioning support column 69 engages with the pair of substrate through holes 60A and 60A in the main control board 60 so that the main control board 60 is two-dimensionally in a plane parallel to the bottom wall 67. Positioned. At this time, the stepped surface 69B of the positioning column 69 abuts against the opening edge of the substrate through hole 60A in the main control board 60, and the upper end surface of the board support column (not shown) is the outer edge portion on the non-electronic mounting surface 60H of the main control board 60. The main control board 60 is held in a state of floating from the bottom wall 67. At this point, for example, electronic components can be mounted on the electronic mounting surface 60J during mass production.

  In this state, the cover body 80 is united with the case body 66. Then, in the process of combining, the sliding contact slope 83A of the locking projection 83C of the board locking portion 83 slides on the edge of the main control board 60, and the flexible beam member 83K of the board locking portion 83 bends. At this time, the lower edge portion of the side wall 82 in the cover body 80 and the locking projection 70A of the locking claw 70 in the case body 66 are also in sliding contact, and the cantilever piece 70H of the locking claw 70 is bent outward. Mu

  When the cover body 80 is further pressed to the case body 66 side and the uniting is completed, as shown in FIG. 9A, the locking projection 83C gets over the edge of the main control board 60 and the flexible beam member 83K The edge of the main control board 60 is sandwiched between the locking surface 83B of the locking projection 83C and the locking surface 83E of the auxiliary locking projection 83D. Thus, the main control board 60 is held on the cover body 80 side, and the electronic mounting surface 60J of the main control board 60 is covered with the board protection wall 81 of the cover body 80. At this time, the locking projection 70A of the locking claw 70 also gets over the side wall 82 of the cover body 80, the cantilever piece 70H is restored, and the locking projection 70A is locked to the outer edge of the cover body 80. . As a result, the case body 66 and the cover body 80 are held in a combined state. As described above, according to the pachinko gaming machine 10 of the present embodiment, the main control board 60 can be locked to the board locking portion 83 simultaneously with the operation of combining the case body 66 and the cover body 80, thereby improving workability. Excellent. Since the auxiliary locking projection 83D is provided on the flexible beam member 83K, for example, even when the substrate protection wall 81 is disposed on the lower side, the main control board 60 falls toward the substrate protection wall 81 side. Such a risk can be reduced.

  Further, when the case body 66 and the cover body 80 are merged, the sealing wall 66F of the case body 66 and the sealing wall 80F of the cover body 80 overlap, and each sealing pin through hole 85A of the sealing wall 80F is sealed. The sealing pin through holes 71A and 72A of the wall 66F and the pin locking holes 63C of the sealing plate 63 are arranged on the same axis. In this state, at each of the left and right ends of the main control board 60, one sealing pin through hole 85A is selected from among the plurality of sealing pin through holes 85A, and the sealing pin 65 is pushed into it. Then, the sealing pin 65 pushes and penetrates a plurality of locking protrusions (not shown) around the pin locking holes 63 </ b> C in the sealing plate 63, and these locking protrusions lock the sealing pins 65. Lock in the groove 65M. Accordingly, the sealing pin 65 is held in a state of penetrating both the sealing wall 66F of the case body 66 and the sealing wall 80F of the cover body 80. Moreover, it is preferable to attach the sealing plug 64 (refer FIG. 5) to the other sealing pin through-hole 85A in which the sealing pin 65 is not inserted. Thus, the main controller 50 is completed. The main controller 50 is assembled to the rear surface of the pachinko gaming machine 10 as described above. When the power of the pachinko gaming machine 10 is turned on, the game of the pachinko gaming machine 10 is comprehensively controlled by the one-chip microcomputer 61A.

  Now, when the pachinko gaming machine 10 is completed, a sample inspection is performed to determine whether the pachinko gaming machine 10 satisfies a predetermined standard by an external organization other than the manufacturer and user of the pachinko gaming machine 10. At this time, the one-chip microcomputer 61A of the main controller 50 is also inspected. Therefore, in order to take out the one-chip microcomputer 61A, as shown in FIG. 9B, the cutting portion 85T corresponding to the sealing pin through hole 85A in which the sealing pin 65 is inserted is broken in the sealing wall 80F. . For this purpose, for example, a flathead screwdriver or the like is abutted and the cut portion 85T is pressed. Then, the plurality of latching claws 70 are bent outwardly from the cantilever pieces 70 </ b> H to release the latching between the latching claws 70 and the cover body 80, and the cover body 80 is separated from the case body 66. Then, the main control board 60 is held by the cover body 80 by being locked with the board locking portion 83, and more than the force that is placed on the board mounting portion 66S of the case body 66 in the main control board 60. Since the force held and held by the stop portion 83 is larger, the case body 66 is detached from the substrate placement portion 66S, and the electronic mounting surface 60J of the main control substrate 60 is covered by the substrate protection wall 81 of the cover body 80. The broken state is maintained. Further, since the main control board 60 is covered on all sides by the side walls 82 of the cover body 80, the main control board 60 cannot be shifted from the side and separated from the cover body 80.

  Therefore, in order to separate the main control board 60 from the cover body 80, the flexible beam member 83K of the board locking portion 83 is bent to release the locking between the locking projection 83C and the main control board 60. . Then, the main beam control board 60 is separated from the cover body 80 by bending the flexible beam member 83 </ b> K of the board locking portion 83. Then, the one-chip microcomputer 61A is removed from the socket 61S, and when the predetermined inspection is completed, the procedure is returned to the original procedure similar to the assembly procedure described above. Further, when the sealing pins 65 are pushed in, one sealing pin through hole 85A is selected from among the plurality of sealing pin through holes 85A left at the left and right ends of the main control board 60, and these are selected. The sealing plug 64 may be removed from the sealing pin 65 and the sealing pin 65 may be pushed in.

  As described above, according to the pachinko gaming machine 10 of the present embodiment, when the case body 66 and the cover body 80 are separated, the main control board 60 is held by the cover body 80 by the locking of the board locking portion 83. In addition, the state where the electronic mounting surface 60J of the main control board 60 is covered with the board protection wall 81 is maintained. Therefore, in order to replace the one-chip microcomputer 61A on the electronic mounting surface 60J, after the case body 66 and the cover body 80 are separated, the locking between the main control board 60 and the board locking portion 83 is further released. Therefore, it takes time and labor to replace the one-chip microcomputer 61A on the electronic mounting surface 60J. Therefore, a so-called goto action for exchanging the one-chip microcomputer 61A with one written with illegal data requires time and effort, and such an illegal action can be suppressed. In the present embodiment, the back surface of the electronic mounting surface 60J of the main control board 60 exposed in a state where the case body 66 and the cover body 80 are separated is a non-electronic mounting surface 60H on which no electronic component is mounted. Therefore, illegal electronic component replacement can be surely prevented.

As shown in FIG. 15, the sealing pin through hole 90 </ b> A is reduced in a stepped shape from the middle in the axial direction, like the sealing pin through hole 85 </ b> A of the first embodiment.

  On the other hand, in this embodiment, the sealing pin through-hole 85A in the sealing wall 80F has a uniform inner diameter. Further, a slit 85N having an open bottom surface is formed in an intermediate portion in the thickness direction of each square protrusion 85, and a sheet metal sealing plate 86 is mounted therein. The sealing plate 86 is formed with a pin locking hole 86A similar to the pin locking hole 63C provided in the sealing plate 63 of the first embodiment. In addition, a flange wall 85H is formed from an end surface facing each side of each square protrusion 85. As shown in FIG. 12, the eaves wall 85 </ b> H has a structure that covers the upper side and both sides of the side area of each square protrusion 85. Further, as shown in FIG. 15, a bank portion 85 </ b> D protrudes from the front end edge of each rib wall 85 </ b> H toward the case body 66 side. Then, when the case body 66 and the cover body 80 are combined, as shown in FIG. 16, the sealing plate member 90 of the case body 66 fits inside the bank portion 85D, and the sealing plate member 90 is sealed. The stop pin through hole 90A, the sealing pin through hole 85A of the rectangular protrusion 85, and the pin locking hole 86A of the sealing plate 86 are arranged coaxially.

  As shown in FIG. 10, in this embodiment, the board | substrate latching | locking part 83 is provided so that it may respond | correspond to each square protrusion 85 one each. And the front-end | tip part of each board | substrate latching | locking part 83 has opposed the sealing pin through-hole 85A (refer FIG. 15) of the square protrusion 85. FIG.

The positioning column 69 in the case body 66 of the present embodiment has a structure in which a support flange 69R is projected from a position near the tip of the cylinder, and the substrate through hole 60A in the main control board 60 is formed on the support flange 69R. The opening edge abuts (see FIG. 15).

  According to the configuration of the present embodiment described above, as shown in FIG. 16A, the case body 66 and the cover body 80 are combined so that the sealing walls 66F and 80F overlap each other, and FIG.

Is prohibited to bend away from the main control board 60. Thereby, the locking force between the board locking part 83 and the main control board 60 is improved.

  When the case body 66 and the cover body 80 are separated, as shown in FIG. 17A, a sealing pin having a sealing pin through hole 90A fitted with the sealing pin 65 in the sealing wall 66F of the case body 66 is provided. The stop plate member 90 is separated from the case body 66 by breaking the priority breaking portion 90T. Then, the sealing pin 65 is left in the cover body 80, and the state where the tip of the sealing pin 65 abuts against the flexible beam member 83K from the side is maintained. Therefore, in this state, the locking between the board locking portion 83 with which the sealing pin 65 is abutted and the main control board 60 cannot be released. Therefore, in order to release the lock between the board locking portion 83 with which the sealing pin 65 is abutted and the main control board 60, as shown in FIG. It is necessary to cut the cutting portion 85T of the portion 85. When the cut portion 85T is cut, the flexible beam member 83K can be elastically deformed, and the main control board 60 can be detached from the cover body 80. Even if the cutting portion 85T is cut for the purpose of fraud, the main control board 60 is removed from the cover body 80, and the electronic components mounted on the main control board 60 are exchanged. It is possible to discover that the cutting unit 85T has been cut, and as a result, it is possible to confirm whether or not the cutting unit 85T has been fraudulent.

  As described above, according to the configuration of the present embodiment, more time and effort are required to replace the electronic components on the electronic mounting surface 60J than the configuration of the first embodiment, and the electronic components mounted on the main control board 60 are required. Unauthorized replacement of parts can be suppressed.
