Description

  The present invention relates to a gaming machine to which a board case containing a control board is attached.

  In general, a pachinko machine, which is a type of gaming machine, includes a plurality of control boards on the back side of the machine. Each control board is a main control board or a sub control board, and includes a CPU (central processing unit), a ROM (read only storage device), and a RAM (read / write storage device). The main control board determines the outline of the contents of the game effect. In addition, the sub control board determines more specific contents of effects based on the contents determined by the main control board.

  By the way, by replacing the ROM of the main control board with a ROM in which an unauthorized program is stored, an unauthorized act of acquiring many prize balls may be performed. Therefore, the main control board is housed in a board case made up of two cases, and both cases are caulked together via caulking cages, thereby preventing an illegal act of removing the main control board and replacing the ROM. Has been proposed (see, for example, Patent Document 1).

JP 2012-10908 A (FIG. 9 etc.)

  However, the substrate case described in Patent Document 1 is structurally weak because the periphery of the caulking ridge is formed only from a resin material. Therefore, if the substrate case is destroyed, the substrate case can be opened. In this case, there is a problem that since a caulking jar having no trace of destruction can be easily obtained, if the case is caulked through the obtained caulking fold, a substrate case in which the ROM is replaced can be produced.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can reliably prevent an illegal act by opening a substrate case.

In order to solve the above problems, in claim 1 (means 1), a gaming machine to which a board case containing a control board is attached, wherein the board case is attached to the gaming machine; A second case attached to the first case so as to cover the first case, and a first caulking portion provided in the first case and a second caulking portion provided in the second case. , which are caulked to each other through the caulking rivet, said the first object caulked portion, said tack fixing member tip is fixed it is press-fitted in caulking rivets provided, caulking member to the second target caulked portion In a state where the second case is attached to the first case and the caulking member is in contact with the head of the caulking rod, and the leading end portion of the caulking rod is press-fitted into the rod fixing member. , said 2 A claw pressing portion that presses the head portion of the caulking rod pressed by the caulking member between the caulking members is provided in the caulking portion, and the caulking member is exposed to the second caulking portion. And the caulking member has an outer diameter larger than the inner diameter of the opening, so that the caulking member cannot be removed from the second caulking portion. In a state where the front end portion of the crimping rod is press-fitted into the flange fixing member by the member, the engagement portion on the crimping member side engages with the engaged portion on the flange pressing portion side, and the crimping member and The gist of the gaming machine is characterized in that it cannot be separated from each other.

  Therefore, according to the first aspect of the present invention, in the state where the second case is attached to the first case, the caulking member housed in the second caulking portion causes the head portion of the caulking rod to be the first caulking portion. By pressing to the side, the leading end portion of the caulking rod is press-fitted into the rod fixing member provided in the first caulking portion, so that it is difficult to remove the crimping rod from the rod fixing member. In addition, since the engagement portion on the crimping member side engages with the engaged portion on the collar pressing portion side, the crimping member and the collar pressing portion cannot be separated from each other. It is maintained in a state of being sandwiched between the heel holding part and the heel holding part. As a result, it becomes more difficult to remove the caulking rod from the rod fixing member. From the above, since the configuration on the second crimped portion side (the crimping member, the collar pressing portion) and the configuration on the first crimped portion side (the collar fixing member) are firmly connected via the crimping collar, It is difficult to remove the second case from one case and open the substrate case. Therefore, it is possible to reliably prevent fraud by opening the substrate case.

  Here, as the control board accommodated in the board case, the main control board that determines the outline of the contents of the game effect, or the sub control board that determines more specific effect contents based on the contents determined by the main control board The main control board is preferable. In other words, the ROM of the main control board stores a program for determining the number of prize balls. If the main control board is accommodated in the board case, the prize balls can be replaced by replacing it with an illegal ROM. This is because it is possible to prevent illegal acts to be acquired.

The invention described in means 2 is the means 1, wherein the caulking member has a shaft portion and a pressing portion that presses the head portion of the caulking rod, and the shaft portion is inserted through the opening, The pressing portion has an outer diameter larger than the inner diameter of the opening, and the gist of the pressing portion is press-fitting the tip end portion of the crimping rod into the rod fixing member by pressing the shaft portion.

Therefore, according to the invention described in the means 2, if the shaft portion of the caulking member is pressed in a state where the second case is attached to the first case, the pressing portion of the caulking member causes the head portion of the caulking rod to be in contact with the first cover. By pressing toward the caulking portion side, the tip end portion of the caulking rod is press-fitted into the rod fixing member, so that it is difficult to remove the crimping rod from the rod fixing member. As a result, the second caulking portion side and the first caulking portion side are more firmly connected via the caulking cage, so that it is even more possible to remove the second case from the first case and open the substrate case. It becomes difficult. Therefore, it is possible to more reliably prevent an illegal act by opening the substrate case.

The invention described in section 3, in the means 1 or 2, wherein the caulking member has the engaging portion, by the engagement portion is engaged with the engaged portion, the head portion of the caulking rivet A caulking cap that covers the shaft, and a pressing portion that presses the head of the caulking rod, the pressing portion is disposed in the caulking cap, and the pressing portion is on the inner surface of the caulking cap. The gist of the invention is that it consists of a caulking cap pin that comes into contact with the head of the caulking tack.

Therefore, according to the invention described in the means 3, when the second case is attached to the first case, the pressing portion of the caulking cap pin presses the head of the caulking rod toward the first caulking portion side. Since the tip end portion of the crimping rod is press-fitted into the rod fixing member, it is difficult to remove the crimping rod from the rod fixing member. In addition, since the engaging portion of the caulking cap engages with the engaged portion on the side of the heel pressing portion, the caulking cap and the heel pressing portion cannot be separated from each other. The portion can securely clamp the head of the caulking ridge with the heel pressing portion. As a result, it becomes more difficult to remove the caulking rod from the rod fixing member. From the above, since the second caulking part side and the first caulking part side are more firmly connected via the caulking ridges, it is possible to remove the second case from the first case and open the substrate case. It becomes even more difficult. Therefore, it is possible to more reliably prevent an illegal act by opening the substrate case.

According to the invention described in means 4 , in the means 3, in the caulking cap, a cylindrical part is inserted so as to pass through the opening and the shaft part is inserted, and presses the cylindrical part and the shaft part simultaneously. Accordingly, the gist of the invention is that the leading end portion of the caulking rod is press-fitted into the rod fixing member.

Therefore, according to the invention described in the means 4, it is not necessary to separately perform the step of pressing the pressing portion of the caulking cap pin with the caulking cap and the step of pressing the head portion of the caulking cap with the caulking cap pin. The man-hour can be reduced accordingly. Therefore, it becomes possible to efficiently manufacture the above excellent substrate case.

Therefore, according to the invention described in the means 5, when pressing the cylindrical portion of the caulking cap and the shaft portion of the caulking cap pin at the same time, when the cylindrical portion and the shaft portion do not protrude from the opening, the leading end portion of the caulking rod Is completely press-fitted into the heel fixing member. As a result, the second caulking part side and the first caulking part side are more firmly connected via the caulking ridge, so that it is more possible to remove the second case from the first case and open the substrate case. It becomes even more difficult. Therefore, it is possible to more reliably prevent an illegal act by opening the substrate case.

The invention described in section 6, in any one of means 1 to 5, wherein the stud fixing member, and the gist thereof to be formed of a metal material.

Therefore, according to the invention described in the means 6, the strength of the heel fixing member is higher than that when the heel fixing member is formed of a resin material. Therefore, even if the substrate case is destroyed, it is difficult to destroy the scissors fixing member, so that it is not possible to illegally obtain a caulking soak that has no trace of destruction. Therefore, it is possible to prevent an illegal act of storing the control board replaced with an illegal ROM in the board case by using the obtained caulking cup. In addition, although the metal material which forms a collar fixing member is not specifically limited, For example, copper, aluminum, iron, titanium, stainless steel etc. can be mentioned.

The invention described in section 7, in any one of means 1 to 6, wherein the substrate case, the caulking cover covering the second object caulked portion from the outside, the first to be caulked portion in the first case A side sticking portion set at a side position and a side position of the second caulking portion in the second case, and the caulking cover includes a cover body that covers the second caulking portion; A fixing portion that extends from the cover body and is fixed to the seal sticking portion on the second case side, the seal sticking portion on the first case side, the seal sticking portion on the second case side, and The gist is that a seal seal is affixed so as to cover the fixing portion, and a seal cover is attached so as to cover the seal seal.

Therefore, according to the invention described in the means 7, the caulking cover is attached so as to cover the second caulking portion, and the fixing portion of the caulking cover and the seal attaching portions on the first case side and the second case side are covered. Since the seal seal is affixed to and attached to the seal cover so as to cover the seal seal, it becomes more difficult to remove the second case from the first case and open the substrate case. Therefore, it is possible to more reliably prevent an illegal act by opening the substrate case. Moreover, since the sticking part is set on each of the first case side and the second case side, it is not necessary to separately provide a member for sticking the seal sticker. As a result, an increase in the number of parts constituting the substrate case can be prevented, and an increase in manufacturing cost can be suppressed.

  As shown in FIGS. 5, 12, 14, and 17, the fixing portion 146 is fixed to the seal sticking portion 143 on the second case 32 side while being accommodated in the recess 222. . The fixed portion 146 is provided with a pair of hooks 193 that protrude downward. Both hooks 193 are engaged with the second case 32 by being inserted into the engagement holes 223 on the bottom surface of the recess 222. In addition, a through hole 147 is provided at a location on the distal end side of the hook 193 in the fixing portion 146. The countersunk screw 148 inserted through the through hole 147 and the screw hole 224 on the second case 32 side is screwed into the screw hole 149a on the first case 31 side, whereby the second case is attached to the first case 31. 32 is fixed.

  The seal seal 142 is attached so as to cover the seal attaching part 143 on the first case 31 side, the seal attaching part 143 on the second case 32 side, and the fixing part 146 (and the head of the countersunk screw 148). An IC chip 142a (see FIG. 12) is built in the seal seal 142 of this embodiment. The IC chip 142a includes an IC chip CPU and a memory for storing an ID. The ID written on the IC chip 142a is read by an IC tag reader. The IC tag reader reads the ID by outputting radio waves, but the radio waves do not affect the game result.

  As shown in FIGS. 3 to 5, 12, 15, and 16, the seal cover 150 is attached to the substrate case 30 so as to cover the sealing seal 142. The seal cover 150 includes an upper wall portion 151 that covers the upper surface (and the fixing portion 146) of the seal sticking portion 143, and a side wall portion 152 that covers the side surface of the seal sticking portion 143 (the connection portion between the first case 31 and the second case 32). And the lower wall part (illustration omitted) which covers the lower surface of the seal sticking part 143 is provided. A hook member 154 including a pair of hooks 153 is provided at both ends of the side wall 152. Note that the hook 153 of each hook member 154 is fitted into the locking holes 155 (see FIGS. 12, 14, and 16) provided on both sides of the seal attaching portion 143, so that the seal cover 150 from the substrate case 30 is provided. Omission is prevented.

  Next, the operation of each member of the substrate case 30 will be described.

(A) Principle of operation in which the substrate case 30 cannot be easily opened First, the second case 32 is moved closer to the caulking member 81 with the hook 71 on the second case 32 side inserted into the guide groove 110 on the first case 31 side. Slide until it stops. At this time, since the hook 71 is hooked on the projection 117 on the first case 31 side, the cases 31 and 32 cannot be opened apart from each other.

  Next, by pressing the caulking member 81 on the second case 32 side, specifically, the cylindrical portion 162 of the caulking cap 82 and the shaft portion 85 of the caulking cap pin 83 at the same time, the distal end portion 62 of the caulking rod 61 is moved. It is press-fitted into the coffin hole 215 of the coffin fixing member 211 (see FIGS. 11A and 11B). The caulking ridge 61 is press-fitted into the pit hole 215 while rotating when it is caulked. Further, as the caulking collar 61 is press-fitted, the engagement protrusion 163 on the caulking cap 82 side engages with the engaged part 92 on the collar pressing portion 91 side, so that the crimping member 81 and the collar pressing portion 91 cannot be separated from each other. It becomes. As a result, since the second case 32 cannot be slid, the substrate case 30 is sealed.

  Thereafter, a caulking cover 144 is mounted from above the caulking member 81, and a flat head screw 148 is screwed to the substrate case 30 side (see FIG. 12). Next, the seal sticker 142 is stuck on the sticker sticking part 143. Further, the hook member 154 (hook 153) of the seal cover 150 is fitted into the locking hole 155 on the substrate case 30 side. As a result, the sealing seal 142 is covered with the seal cover 150, so that the substrate case 30 cannot be easily opened.

(B) Operation principle that makes it difficult to open the substrate case 30 by the caulking member 81 In the present embodiment, when the engagement protrusion 163 on the caulking cap 82 side is fitted into the engagement hole 94 on the flange pressing portion 91 side, the engagement is performed. Since the protrusion 163 is caught by the heel pressing portion 91, it is difficult to remove the caulking cap 82 from the heel pressing portion 91. Further, the gap between the outer peripheral surface of the cylindrical portion 162 of the caulking cap 82 and the inner side surface of the opening 52 of the second caulking portion 51, the inner side surface of the through hole 164 of the cylindrical portion 162, and the shaft portion of the caulking cap pin 83. Since the gap between the outer peripheral surface 85 and the outer peripheral surface 85 is extremely small (0.5 mm in this embodiment), it is difficult to grip and lift the caulking cap 82. Due to the above, it becomes difficult to remove the caulking cap 82, so that the substrate case 30 cannot be easily opened.

(C) Operation principle that makes it difficult to open the substrate case 30 by the caulking cover 144 and the seal cover 150 In this embodiment, when the caulking cover 144 is attached and the flat head screw 148 is screwed, the caulking cover 144 is provided. Since the pair of projecting portions 191 are inserted into the housing recess 192 on the first caulking portion 41 side, the second case 32 cannot be slid. Furthermore, since the pair of hooks 193 provided on the caulking cover 144 are inserted into the hooks 193 on the second case 32 side and locked, it is difficult to remove the caulking cover 144 from the second case 32. When the seal cover 150 is attached, the two hook members 154 (that is, the four hooks 153) provided on the seal cover 150 are locked in the locking holes 155 on the substrate case 30 side, so that the seal cover 150 is removed. It becomes difficult to remove from the substrate case 30. In addition, in this case, since the countersunk screws 148 covered by the seal cover 150 cannot be touched, it is difficult to remove the countersunk screws 148 that fix the cases 31 and 32 and the caulking cover 144 to each other. Therefore, the substrate case 30 cannot be easily opened.

(D) Principle in which traces remain when the substrate case 30 is opened Note that when the substrate case 30 is opened, four seal cover cutting portions 181 (see FIG. 15) that connect the side wall portion 152 and each hook member 154 are used. Cut and remove the seal cover 150. Next, the sealing seal 142 covered with the seal cover 150 is peeled off, and the countersunk screw 148 covered with the sealing seal 142 is removed. Then, the cutting portion 182 (see FIG. 17A) provided at the connection portion between the cover main body 145 and the fixing portion 146 is cut, and the covering of the second caulking portion 51 by the cover main body 145 of the caulking cover 144 is released. To do. Furthermore, the cutting | disconnection part 184 (refer FIG.17 (b)) provided in a pair of root rib 183 which connects the 2nd crimping part 51 and the 2nd case 32 is cut | disconnected, and the 2nd case 32 is removed. As a result, the trace that the seal seal 142 is damaged, and the trace that the seal cover 150, the caulking cover 144, and the root rib 183 are cut remain. Moreover, the ID written in the IC chip 142a cannot be read due to the damage of the seal sticker 142.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 of the present embodiment, the pressing portion 86 of the caulking cap pin 83 pushes the head 63 of the caulking rod 61 into the first caulking portion with the second case 32 attached to the first case 31. By pressing toward the 41 side, the leading end 62 of the crimping collar 61 is press-fitted into the collar fixing member 211 provided on the first crimping section 41. As a result, it becomes difficult to remove the caulking rod 61 from the rod fixing member 211. In addition, since the engagement protrusion 163 of the caulking cap 82 is engaged with the engaged portion 92 on the side of the hook pressing portion 91, the caulking cap 82 and the hook pressing portion 91 cannot be separated from each other. The pressing portion 86 that comes into contact with the inner side surface 82 a can securely sandwich the head 63 of the caulking rod 61 with the rod pressing portion 91. As a result, it becomes more difficult to remove the caulking rod 61 from the rod fixing member 211. From the above, the configuration on the second caulking portion 51 side (the caulking member 81 and the hook pressing portion 91) and the configuration on the first caulking portion 41 side (the hook fixing member 211) are more firmly connected via the caulking rod 61. Therefore, it becomes more difficult to remove the second case 32 from the first case 31 and open the substrate case 30. Therefore, it is possible to more reliably prevent an illegal act caused by opening the substrate case 30.

  (2) In this embodiment, the step of pressing the pressing portion 86 of the caulking cap pin 83 by the caulking cap 82 and the step of pressing the head 63 of the caulking rod 61 by the caulking cap pin 83 do not have to be performed separately. Therefore, the man-hour can be reduced correspondingly. Therefore, it becomes possible to manufacture the above excellent substrate case 30 efficiently.

  (3) In the present embodiment, the clearance between the outer peripheral surface of the cylindrical portion 162 of the caulking cap 82 and the inner surface of the opening 52 of the second caulking portion 51, and the inner surface and the caulking of the through hole 164 of the cylindrical portion 162. Since the gap between the cap pin 83 and the outer peripheral surface of the shaft portion 85 is extremely small (0.5 mm in this embodiment), it is difficult to grip and lift the caulking cap 82. Moreover, since the cap body 161 of the caulking cap 82 has an outer diameter (15 mm) larger than the inner diameter (7.5 mm) of the opening 52 provided in the second caulking portion 51, It becomes difficult to remove the caulking cap 82. For the above reasons, it becomes difficult to remove the caulking cap 82, so that the substrate case 30 cannot be easily opened.

  (4) In this embodiment, since the head of the countersunk screw 148 is covered with the seal seal 142, it is not necessary to provide a part for covering the head of the countersunk screw 148 separately from the seal seal 142. Therefore, an increase in the number of parts constituting the substrate case 30 can be prevented, and an increase in manufacturing cost can be suppressed.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

  In the present embodiment, the structure of the caulking member is different from that of the first embodiment. It can be said that the caulking member of the present embodiment is obtained by integrating the caulking cap 82 and the caulking cap pin 83 of the first embodiment. Specifically, as shown in FIG. 18, the caulking member 241 includes a shaft portion 242 and a pressing portion 243 that presses the head 63 of the caulking rod 61. The shaft portion 242 has a rod shape with an outer diameter of 7.0 mm and a height of 14 mm, and is inserted through the opening 52 provided in the top plate portion 55. In the state before the tip 62 of the crimping rod 61 is press-fitted into the flange 215 of the rod fixing member 211, the length (12 mm) of the portion protruding from the opening 52 in the shaft 242 is the length of the tip 62. It is the same as the length. On the other hand, the pressing portion 243 has a cylindrical shape with an outer diameter of 10 mm × height of 7 mm, and is disposed in the second caulking portion 51. That is, the pressing portion 243 has an outer diameter larger than the inner diameter (7.5 mm) of the opening 52. A concave portion 244 for inserting the head 63 of the crimping rod 61 is provided at the tip of the pressing portion 243. Further, the engaged portion 246 on the side of the flange pressing portion 245 is engaged with the outer peripheral portion on the proximal end side of the pressing portion 243. Therefore, in this embodiment, when the shaft portion 242 of the caulking member 241 is pressed, the distal end portion 62 of the caulking rod 61 is press-fitted into the rod hole 215 of the rod fixing member 211.

  Therefore, according to the present embodiment, if the shaft portion 242 of the caulking member 241 is pressed with the second case 32 attached to the first case 31, the pressing portion 243 of the caulking member 241 becomes the head of the caulking rod 61. By pressing 63 toward the first caulking portion 41, the tip end portion 62 of the caulking rod 61 is press-fitted into the rod fixing member 211. For this reason, it becomes difficult to remove the caulking rod 61 from the rod fixing member 211. As a result, the second caulking portion 51 side and the first caulking portion 41 side are more firmly connected via the caulking rod 61, so that the second case 32 is removed from the first case 31 and the substrate case 30 is removed. Opening becomes even more difficult. Therefore, it is possible to more reliably prevent an illegal act caused by opening the substrate case 30.

  In addition, you may change this embodiment as follows.

  In the above embodiment, the heel fixing member 211 is press-fitted into the press-fitting hole 44 of the first caulking portion 41. However, the heel fixing member 211 may be fixed to the first caulking portion 41 using other methods. For example, the hook fixing member 211 may be embedded in the main body portion 42 of the first caulking portion 41 by an insert molding method. Further, the heel fixing member 211 may be fixed to the main body portion 42 by interposing an adhesive between the outer peripheral surface of the heel fixing member 211 and the inner side surface of the press-fitting hole 44.

  In the above embodiment, the heel fixing member 211 has a circular cross section, but may be changed to other shapes such as a hexagonal cross section, an octagonal cross section, and a rectangular cross section. If it does in this way, when pressing the crimping collar 61 into the collar hole of the collar fixing member, it can prevent that the collar fixing member rotates with the crimping collar 61.

  The configuration of the substrate case 30 of the above embodiment may be applied to a substrate case that houses a control board (such as a payout control board) different from the main control board.

  Next, in addition to the technical ideas described in the claims, the technical ideas grasped by the embodiment described above are listed below.

  (1) In said means 4, the said cylinder part has a through-hole which the said shaft part penetrates, The clearance gap between the outer peripheral surface of the said cylinder part, and the inner surface of the said opening part, and the inner surface of the said through-hole And a gap between the outer peripheral surface of the shaft portion is 0.5 mm or less.

  (2) In any one of the above means 1 to 7, the first case and the second case are formed using a colorless and transparent resin material.
