Each of these electrical components is housed in a board case and intensively connected to a genuine control board suitable for each electronic control game. In the state or the like, the operation is controlled according to the respective movable conditions. This control board is required to be used normally under the condition that it has the same software program content as designed and configured by the manufacturer and the same content that conforms to a rigorous test at a testing organization.

  The substrate case is composed of a plate-like member and a cover-like member that are separated from each other, and the control board is set in the plate-like member and the cover-like member so as to be handled as a single unit in a box shape unit. It is configured. As an example of measures for preventing unauthorized modification / change on the premise of normal use with proper control contents (software program), a cylindrical portion is integrated with the matching portion between the plate-like member and the cover-like member, respectively. These cylindrical parts are fixed with special fixing tools such as one-way screws, special pins and scissors developed for the purpose of preventing fraud, and the heads of the special fixing tools are fitted into the cylindrical parts. A technique for assembling and sealing the dish-like member and the cover-like member by covering with a member has been proposed.

  In the case of the substrate case to which the anti-tampering measure is taken, there is a case where the control board is normally inspected and confirmed. At this time, it is necessary to cut the cylindrical portion fixed by the dedicated fixing tool. Since the plate-like member and the cover-like member need to be assembled again after the inspection, the substrate case is provided with a plurality of spare cylindrical portions. In addition, the number of spare dedicated fixing tools and sealing members such as lid members are detachably attached to the substrate case by the same number as the number of spare cylindrical portions.

However, since the sealing member is attached to the outside of the substrate case, the sealing member before use may be stolen and used illegally. In addition, it is pointed out that the sealing member may be dropped and lost when the board case is shipped or delivered. In view of this, a proposal has been made to prevent the sealing member from being stolen or lost by providing a storage unit inside the substrate case and storing the sealing member in the storage unit (see, for example, Patent Document 1).

  The thickness of the main body 42 in the first holding member 41 is set to be smaller than the separation distance between the projecting ring part 30 and the projecting ring part 30 adjacent to each other in the axial direction in the sealing lid 29. Accordingly, when the shaft portion 29a is inserted into the holding through hole 44a to a position where the main body portion 42 faces between the adjacent protruding ring portions 30 and 30, the main body portion 42 is sandwiched between the protruding ring portions 30 and 30, The sealing lid 29 is prevented from falling off from the first holding member 41.

  As shown in FIGS. 7 and 9, the second storage portion 32 has a simple box-like shape that opens to the opening side of the cover-like member 22, and a second holding member 47, which will be described later, is stored inside the second storage portion 32. It is configured to be detachably attached. The second storage portion 32 has a support portion 45a facing inward at a position retracted one step from the open end of the side walls 45, 46 on the side walls 45, 46 on both sides in the longitudinal direction along the left edge 22d of the cover-like member 22. 46a projectingly, and the second holding member 47 is placed on both support portions 45a, 46a.

  As shown in FIG. 9, the second lid portion 34 has a flat plate-like simple shape that substantially matches the internal shape of the opening 32 a in the second storage portion 32, and includes the dish-like member 21 and the cover-like member 22. When the combination is set, the opening portion 32a of the second storage portion 32 is configured to be closed without a substantial gap.

  As shown in FIG. 9, the second holding member 47 stored in the second storage portion 32 includes a rectangular plate-shaped main body portion 48 that can be stored in the second storage portion 32, and the main body portion 48. The contact piece portion 49 is bent at one end portion (the other end portion), and a plurality of holding through holes (mounting portions) 50 are formed in the main body portion 48. The length dimension of the main body 48 is set to be larger than the dimension in the longitudinal direction of the second storage section 32 (the distance between the side walls 45 and 46), and the second holding member 47 is stored in the second storage section 32. At this time, the abutting piece portion 49 abuts the inner surface of the corresponding one side wall (other side wall) 45 in the longitudinal direction, and the other end portion (one end portion) of the main body portion 48 corresponds to the other side wall (one side in the longitudinal direction). (Side wall) 46 is configured to contact the inner surface. The second holding member 47 is formed of an elastic body such as elastically deformable synthetic resin or rubber. When the second holding member 47 is stored in the second storage portion 32, the contact piece 49 and the main body portion are formed. The other end of 48 is elastically brought into contact with the inner surfaces of the corresponding side walls 45 and 46 to be positioned and held.

  The holding through hole 50 formed in the main body portion 48 of the second holding member 47 functions to hold the spare screw 25, and the holding through hole 50 corresponds to the spare screw 25. The same number as the number is formed in the main body 48. The holding through hole 50 is set to have a diameter smaller than that of the screw shaft portion 25a of the screw 25. By inserting the screw shaft portion 25a of the screw 25 into the holding through hole 50, the screw 25 becomes the second holding member. 47 is configured to be held.

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

  The board case 17 is assembled in a separate assembly department from the main assembly line of the pachinko machine 10 in the manufacturer. First, a process of mounting the preliminary sealing lid 29 and the screws 25 on the corresponding holding members 41 and 47 will be described. That is, the sealing lid 29 is held by the first holding member 41 by inserting the shaft portion 29a to a predetermined position through the holding through hole 44a in each mounting portion 44 of the first holding member 41. In this case, since the first holding member 41 is formed of an elastic body, when the shaft portion 29a having a diameter larger than that of the holding through hole 44a is inserted, the holding through hole 44a is formed by elastic deformation of the main body portion 42. The shaft portion 29a can be easily inserted and expanded, and after insertion, the shaft portion 29a can be securely held by elasticity. In addition, in the case of the sealing lid 29 in which the shaft portion 29a is formed with the projecting ring portion 30 projecting radially outward, the projecting portion 30 becomes resistant when the shaft portion 29a is inserted into the holding through hole 44a. It becomes difficult to insert. However, since the mounting portion 44 of the embodiment has a plurality of recesses 44b that allow the holding through hole 44a to be expanded on the inner periphery of the holding through hole 44a, the shaft portion 29a and the projecting ring portion 30 are provided. The holding through-hole 44a can be easily expanded to reduce the resistance when the projecting ring portion 30 passes, so that the sealing lid 29 can be easily inserted into the mounting portion 44. Further, if the shaft portion 29a is inserted into the holding through hole 44a until the main body portion 42 of the first holding member 41 faces between the protruding ring portion 30 and the protruding ring portion 30 adjacent to the sealing lid 29, The main body 42 is sandwiched between the projecting ring portions 30, 30, so that the sealing lid 29 is more reliably prevented from falling off the first holding member 41.

  The screws 25 are held by the second holding member 47 by inserting the screw shaft portions 25a to the predetermined positions through the holding through holes 50 of the second holding member 47. In this case, since the second holding member 47 is formed of an elastic body, when the screw shaft portion 25a having a diameter larger than the holding through hole 50 is inserted, the holding through hole 50 is easily expanded. The screw shaft portion 25a is easily inserted, and after insertion, the screw shaft portion 25a is securely held by elasticity.

  As described above, since each holding member 41, 47 is formed of an elastic body, when the sealing lid 29 or the screw 25 is attached to the holding member 41, 47, the sealing lid 29 or the screw 25 is damaged. Is prevented. Further, the holding members 41 and 47 themselves are also prevented from being damaged, and the holding members 41 and 47 can be reused.

  Next, the first holding member 41 to which the plurality of spare sealing lids 29 are attached and the second holding member 47 to which the plurality of spare screws 25 are attached correspond to the corresponding first storage portions in the cover-like member 22. 31 and the second storage part 32. As for the first holding member 41, as shown in FIGS. 8 and 10, the main body portion 42 is placed in contact with the support portions 37 a and 38 a of the first storage portion 31. At this time, an end portion of the main body portion 42 where the contact piece portion 43 is not formed contacts the inner surface of the corresponding side wall 38 in the other longitudinal direction of the first storage portion 31, and the contact piece portion 43 is the first portion. The first holding member 41 is stored and held in the first storage portion 31 by contacting the inner surface of the corresponding one side wall 37 in the longitudinal direction of the storage portion 31.

  As for the second holding member 47, similarly to the first holding member 41, as shown in FIG. 9, the main body portion 48 is placed in contact with the support portions 45 a and 46 a of the second storage portion 32. At this time, the end portion of the main body portion 48 where the contact piece portion 49 is not formed contacts the inner surface of the corresponding side wall 46 in the other longitudinal direction of the second storage portion 32, and the contact piece portion 49 is second. The second holding member 47 is stored and held in the second storage portion 32 by contacting the inner surface of the corresponding one side wall 45 in the longitudinal direction of the storage portion 32. In this way, each of the storage portions 31 and 32 only stores the holding members 41 and 47 to which the plurality of sealing lids 29 and screws 25 are attached in advance, so that one sealing lid 29 and one screw 25 are provided. Compared to the conventional technology of storing each item, the work becomes much easier and the burden on the operator can be reduced. In addition, since it is not necessary to mold portions for individually attaching the sealing lid 29 and the screws 25 to the storage portions 31 and 32, the storage portions 31 and 32 can be formed in a simple shape, and can be easily molded and manufactured. Can be cheap

  Next, in a state where the main control board 16 is positioned on the dish-like member 21, the first holding member 41 and the second holding member 47 are set in correspondence with the first storage portion 31 and the second storage portion 32 as described above. The stored cover-like member 22 is assembled and set on the dish-like member 21. At this time, since each holding member 41, 47 is in surface contact with the corresponding side wall 37, 45 of the contact piece portion 43, 49, each holding member 41, 47 is from the corresponding storage portion 31, 32. It does not drop off easily, and it is not necessary to work so that the holding members 41 and 47 do not fall off when assembling the plate-like member 21 and the cover-like member 22, and workability is good.

  When the plate-like member 21 and the cover-like member 22 are assembled and set, as shown in FIGS. 4, 5, 8 and 9, the first storage portion 31 and the second storage portion 32 formed on the cover-like member 22 are The first lid portion 33 and the second lid portion 34 formed on the dish-like member 21 are closed, and the holding members 41 and 47 are completely prevented from falling off from the storage portions 31 and 32. Also, the bottom side of the corresponding bottomed cylindrical portion 24 molded on the lower edge portion 22a of the cover-like member 22 is aligned with the opening side of each connecting portion 23 molded on the lower edge portion 21a of the dish-like member 21. (See FIG. 3).

  As shown in FIG. 6, the screw shaft portion 25 a of the screw 25 inserted through the through hole 28 a of the bottomed cylindrical portion 24 is connected to the coupling portion 26 at an arbitrary position including the aligned connecting portion 23 and the bottomed cylindrical portion 24. The plate-like member 21 and the cover-like member 22 are fixed by screwing into the through holes 23a of the aligned connecting portions 23. Next, by inserting the sealing lid 29 into the insertion hole 27 of the bottomed cylindrical portion 24, the head 25b of the screw 25 is covered with the sealing lid 29, and access to the screw 25 from the outside is completely completed. Can be prevented.

  The sealing lid 29 is configured such that a plurality of projecting ring portions 30 formed on the shaft portion 29a are bitten into the inner peripheral surface of the bottomed cylindrical portion 24 so as to prevent the sealing lid 29 from coming off. Easy removal can be prevented with a simple configuration. Further, since the bottomed cylindrical portion 24 is made of synthetic resin, the sealing lid 29 is made of metal, so that the projecting ring portion 30 is firmly bitten into the inner peripheral surface of the bottomed cylindrical portion 24. Can do. Moreover, since the projecting ring portion 30 is formed over the entire circumference of the shaft portion 29a, the area that bites into the inner peripheral surface of the bottomed cylindrical portion 24 is large, and the sealing lid 29 from the bottomed cylindrical portion 24 has a large area. Removal may be difficult. Furthermore, since the peripheral surface portion 30a of the protruding ring portion 30 is formed in parallel with the inner peripheral surface of the bottomed cylindrical portion 24, the contact area between the bottomed cylindrical portion 24 and the protruding ring portion 30 can be further increased. The removal of the sealing lid 29 from the bottomed cylindrical portion 24 can be further suppressed. Further, it is not necessary to form the engaged portion or the like inside the bottomed cylindrical portion 24, and the bottomed cylindrical portion 24 can be made simple to reduce the manufacturing cost.

  As shown in FIGS. 4 and 5, the head 29b of the sealing lid 29 fitted into the insertion hole 27 of the bottomed cylindrical portion 24 is completely accommodated in the large-diameter hole 27a. An illegal act of gripping and removing the head 29b of the sealing lid 29 using a tool can be prevented. Further, since the end surface 29c of the head portion 29b of the sealing lid 29 is formed in a curved shape, even if an illegal act of hitting a driver or the like into the end surface 29c is performed, the driver or the like slips to cause the end surface 29c to slip. It is not easily struck, and cheating can be suppressed. In other words, the sealing lid 29 has a high defense against the act of illegally removing the sealing lid 29 fitted into the bottomed cylindrical portion 24.

  The projecting ring portion 30 of the sealing lid 29 is formed with a tapered surface 30b at the front end edge in the direction of insertion into the bottomed cylindrical portion 24. Therefore, the sealing lid 29 is fitted into the bottomed cylindrical portion 24. In this case, the inner peripheral surface of the bottomed cylindrical portion 24 is gradually widened by the tapered surface 30b, and the sealing lid 29 can be easily fitted into the bottomed cylindrical portion 24, and the inner periphery of the projecting ring portion 30 can be reduced. It is suppressed that the surface is cut. Further, since there is a gap between the projecting ring part 30 and the projecting ring part 30 that are separated in the axial direction, a portion that deforms when the sealing lid 29 is fitted into the bottomed cylindrical part 24 escapes into the gap. By entering, it can suppress that insertion resistance becomes large by a deformation | transformation part, and insertion of the sealing lid | cover 29 becomes easy. Furthermore, since the radial dimension of the plurality of projecting ring portions 30 is set so as to increase in order from the front side to the rear side in the insertion direction with respect to the bottomed cylindrical portion 24, the plurality of projecting ring portions 30 are formed. However, the bottomed cylindrical portion 24 can be easily fitted. In addition, since the inner peripheral surface of the bottomed cylindrical portion 24 is prevented from being scraped by the tapered surface 30b of each projecting ring portion 30, the inner peripheral surface is scraped by the first projecting ring portion 30 so that the inner diameter is reduced. Does not increase, and the rear-side protruding ring portion 30 can be surely bitten into the inner peripheral surface.

  As described above, the substrate case 17 sealed so as not to be illegally opened is mounted and set on the back cover 13 for use as shown in FIG. In this case, the first storage unit 35 and the second storage unit 36 are provided not on the board case 17 in which the main control board 16 is stored, but on the side edge of the board case 17. The storage units 35 and 36 do not hinder the visibility of the main control board 16 from the outside. Further, since the preliminary sealing lid 29 and the screw 25 are stored in the storage units 35 and 36, the sealing lid 29 and the screw 25 are prevented from being stolen. In addition, when the substrate case 17 is mounted and set on the back cover 13 or when the substrate case 17 is transported, the sealing lid 29 and the screw 25 are prevented from dropping from the substrate case 17 and being lost.

  When the main control board 16 is properly inspected in the board case 17 that cannot be tampered with by the screw 25 and the sealing lid 29, the engagement pieces 21b and 22b are cut to fix the screws. The fixed joint 26 is cut off. When the substrate case 17 is sealed again after the inspection, the sealing lid 29 is removed from the first holding member 41 taken out from the first storage portion 31 of the cover-like member 22 and the second cover 32 is taken out from the second storage portion 32. 2 Remove the screw 25 from the holding member 47. After the holding members 41 and 47 are stored in the corresponding storage portions 31 and 32, the plate-like member 21 and the cover-like member 22 are assembled and set in the same manner as described above, and the screws 25 are screwed into the corresponding connecting portions 26. Resealing is completed by inserting the sealing lid 29.

  Since the holding members 41 and 47 are separate from the plate-like member 21 and the cover-like member 22 as described above, the sealing lid 29 and the screw 25 are removed from the outside taken out from the storage portions 31 and 32. Workability is good. Further, in the first holding member 41 accommodated in the first accommodating portion 31, as shown in FIG. 10, in the state where the dish-like member 21 is removed from the cover-like member 22 and the first accommodating portion 31 is opened, A part of the contact piece 43 of the first holding member 41 is exposed through the notch 40. Accordingly, the first holding member 41 can be easily taken out from the first storage portion 31 by grasping the exposed portion of the contact piece portion 43.

  When the substrate case 17 itself is damaged, or when re-sealing becomes impossible by using all the connecting portions 26, or when the pachinko machine is recovered, the holding members 41 and 47 are attached to another substrate. Can be reused in the case, improving recyclability.
