JP 2001-276386 A

  Conventionally, this type of substrate storage case includes a rectangular case body in which a control board is stored from a storage port, a lid that covers the storage port of the case body, and a sealing member that maintains this cover state. Is done.

The sealing member is provided with a plurality of case-side sealing members attached to the case main body via a connecting portion, and provided to the lid via the connecting portion, and is attached correspondingly to the case-side sealing member. In addition, a plurality of lid-side sealing members and specially shaped screws such as one-way screws (one-way screws) for fixing both sealing portions and other screwing means are included. Then, by tightening the one-way screw, the housing opening of the case main body is sealed by the lid body and is prevented from being opened.

  In addition, if at least a pair of the plurality of case-side sealing members and the plurality of lid-side sealing members are screwed, the sealing is sufficiently performed, but the case-side sealing member and The reason for arranging a plurality of lid-side sealing members is to enable repeated use of the same number of sealing members.

  By the way, when this type of sealing member is used, the substrate storage case once closed cannot be opened unless the connecting portion is cut. The one-way screw can be turned only in one direction, that is, in the tightening direction. However, the one-way screw is exposed to the outside of the case. For this reason, if a special tool is used, even if it is a one-way screw, the one-way screw can be removed by releasing the tightening, and an illegal act is possible.

  The present invention is for solving the above-mentioned problems, and the problem to be solved is to provide a technology capable of sealing a lid body that closes the housing opening of the case body without using a one-way screw. There is to do.

  The present invention employs the following means in order to solve the above problems.

  (1) That is, the substrate sealing structure used in the substrate storage case of the present invention has a substrate storage port into which a control substrate having a storage medium for storing a game program is stored. Is a control substrate sealing structure used for a substrate storage case having a case main body, a lid provided on the case main body for covering the substrate storage port, and a sealing portion for maintaining the cover state. The control board sealing structure is applied to the sealing part, the sealing part is provided in the main body side sealing part provided in the case main body, and the lid body, and the substrate storage port is provided in the When closed by a lid, a lid-side sealing portion that is coupled to the main-body-side sealing portion, and the main body-side sealing portion and the lid-side sealing portion in a state where the substrate storage port is closed by the lid. A bridge member to be inserted, and the main body side seal And the lid-side sealing portion each have a coupling portion that is a portion where both sealing portions are coupled, and the bridging member is connected to the coupling portion of the main-body-side sealing portion in the inserted state. It has an engagement piece for permanently fastening the bridging member to the sealing portion by engaging it, and the lid-side sealing portion is moved by the engagement piece before the fastening. It has a temporary fixing part which prevents the progress of the bridging member and holds the bridging member on the lid side sealing part.

  According to the present invention, when the housing opening of the case body is covered with the lid, the main body side sealing portion provided in the case main body and the lid side sealing portion provided in the lid body are coupled at the coupling portion. However, the lid body cannot be detached from the case body by itself.

  Since the bridging member has an engagement piece for permanently fastening the bridging member to the sealing part so that it cannot be pulled out, even if the coupling of the main body side sealing part and the lid side sealing part is released and both are separated, The bridging member is not separated from the main body side sealing portion and the lid side sealing portion. Then, the movement of the lid is suppressed, and the substrate storage opening cannot be opened sufficiently. For this reason, the control board accommodated in the case main body cannot be taken out from the board housing opening or is difficult to take out.

In order to remove the control board from the board storage port, it is necessary to release the main fastening state of the bridging member. For this purpose, the book is forcibly cut by the bridging member or by deforming the engaging piece. It is necessary to release the clasp to release the connection between the main body side sealing portion and the lid side sealing portion. When the bridging member is cut or the engaging piece is deformed, the trace remains on the bridging member. Therefore,
The traces of the bridging members are useful for determining whether fraud has been performed.

  In addition, it is verified that the control board housed in the case body has not been replaced, the storage medium mounted on the control board has not been tampered with, or a circuit component member including a storage medium provided on the control board or the control board. When a legitimate act is performed, such as when exchanging, even if the trace remains on the tail bridge member, there is no problem by replacing it with a new bridge member. It is possible to eliminate the occurrence of future suspicion that fraudulent acts may have been performed due to the traces caused by the exchange.

  Moreover, since the said lid side sealing part has a temporary fixing part which temporarily fixes the said bridge member to the said lid side sealing part via the said engagement piece before the said main fastening, You can confirm whether or not you really want to seal it.

  The lid-side storage body 179 is a plate-shaped body whose overall shape is bent into a substantially U-shape in a cross-section such as the channel steel being laid down, like the main body-side storage body 168, and the lid-side box portion 178. The space 179S is detachably stored.

The lid-side storage body 179 includes a top plate portion 179a (one surface of the facing surface of the lid-side storage body) as a closing lid that closes the opening 180 of the lid-side box portion 178, and a bottom plate portion that faces the top plate portion 179a. 179b (the other surface of the facing surface of the lid-side storage body) and a connecting portion 179c that connects both plate portions.
A circular fitting hole 185 is formed in the central portion of the top plate portion 179a. A small hole 185 a that faces outward from the fitting hole 185 is formed at the periphery of the fitting hole 185.

  The top plate portion 179a has the same width as the bottom plate portion 179b as shown in FIGS. The length of the top plate portion 179a is such that the free end edge 179a1 of the top plate portion 179a comes into contact with one edge of the lid side box portion 178 when the lid side storage body 179 is stored in the space 179S of the lid side box portion 178. The dimensions and the height dimension of the lid-side storage body 179 are determined (see FIGS. 6 and 7).

  Since the lid-side storage body 179 is substantially U-shaped in cross section as described above, the degree of freedom is high, and the angle α between the top plate portion 179a and the connecting portion 179c and the bottom plate portion 179b The angle β between the connecting portion 179c and the connecting portion 179c is deformed according to the inclination angle of the wall surface of the space 179S having a shape like a truncated quadrangular pyramid of the lid-side box portion 178 in which the lid-side storage body 179 is stored. .

A rectangular through hole 188 having a rectangular shape parallel to the extending direction of the bottom plate portion 179b is formed at the center of the bottom plate portion 179b. A pair of ridges 186 extending in parallel with the rectangular through hole 188 sandwiched between the rectangular through holes 188 on the lower surface of the bottom plate portion 179b (the surface on the main body side housing 168 side). Is formed. The pair of protrusions 186 are fitted into the pair of parallel grooves 183 of the lid side box portion 178 in a tight fit.

  The pair of parallel grooves 183 of the lid-side box 178 and the pair of protrusions 186 of the lid-side storage body 179 are interchanged to form a pair of parallel grooves 183 on the bottom plate 179b of the lid-side storage body 179. A pair of protrusions 186 may be formed on the lid side box portion 178.

  The top plate portion 179a has a groove 187 parallel to the free end edge 179a1 at a position closer to the free end than the center.

  The groove 187 is used to bend the top plate portion 179a in an unrepairable state by bending the top plate portion 179a at a position where the groove 187 is formed when an external force is applied to the top plate portion 179a. Then, it calls the lid side folding groove 187. The top plate portion 179a functions as a lid that closes the opening 180 of the lid-side box portion 178, and is therefore referred to as a lid-side closure lid. The lid-side folding groove 187 is a groove having a triangular cross section that opens downward.

  The bridging member 169 is made of an elastically deformable resin member, and includes a rod-shaped bridging member main body 190, a first engagement piece 191 located at the tip of the bridging member main body 190, and the bridging member main body 190. It has the disk-shaped press part 193 located in the terminal, and the 2nd engagement piece 192 located between both.

  The entire length of the bridging member main body 190 is longer by the thickness of the pressing portion 193 than the lid side box portion 178 of the lid side sealing portion 165.

  The first engagement piece 191 is a snap coupling piece in the shape of the letter W of the alphabet, and coupled with the elasticity of the bridging member 169, the first engagement piece 191 is moved in the width direction (FIGS. 5 to 7). When the external force is applied so as to compress the first engagement piece 191 from the left and right direction), the first engagement piece 191 contracts, and when the external force is removed, the first engagement piece 191 returns.

  When the bridging member 169 is inserted into the lid side sealing portion 165 and the main body side sealing portion 166 and passes through the stepped through hole 182o of the lid side box portion 178 or the through hole 172o of the main body side box portion 167, the lid side It snap-joins with the wall surface 182 in which the stepped through-hole 182o of the box part 178 is formed, or the wall surface 172 in which the through-hole 172o of the main body side box part 167 is formed (FIGS. 6 and 7).

  In the first engagement piece 191 and each hole through which the first engagement piece 191 passes, the first engagement piece 191 is larger than each hole, and the first engagement piece 191 can pass through each hole. This is because the combined piece 191 is compressed in the width direction as described above.

  When the bridging member 169 is snap-coupled at the main body side sealing portion 166, the ceiling wall surface 172 of the main body side box portion 167 and the main body side storage body are formed by the first engagement piece 191 and the second engagement piece 192 of the bridging member 169. Since the top plate portion 168a of 168 is sandwiched, the bridging member 169 cannot be removed from the sealing portion 164. At this time, the first engagement piece 191, the second engagement piece 192, and the pressing portion 193 of the bridging member 169 are respectively large in the space 167 </ b> S of the main body side storage body 168 and the stepped through hole 182 o of the lid side box portion 178. It is located in the diameter portion 182o2 and the space 179S. In this state, the bridging member 169 is in a fully-fastened state or is permanently fastened (see FIG. 7).

From this point of view, the first engagement piece 191 and the second engagement piece 192 are referred to as engagement pieces for fastening the bridging member 169 so that it cannot be pulled out. The ceiling wall surface 172 of the main body side sealing portion 166 and the top plate portion 168a of the main body side storage body 168 are referred to as a main fastening portion. Then, the second engagement piece 192 crosses the rectangular through hole 188 of the lid side sealing portion 165 before the main fastening, thereby preventing the bridging member 169 from proceeding and sealing the bridging member 169 to the lid side. Holding to the part 165 is called temporary fixing (refer FIG. 6).

  The pressing portion 193 is a disk body for pushing the bridging member 169 toward the coupling portion, and the rear end of the bridging member 169 (progress of the bridging member main body in a state orthogonal to the axial direction of the bridging member 169). (The end opposite to the direction).

  The pressing portion 193 is large enough to fit in the fitting hole 185 formed in the top plate portion 179a of the lid side storage body 179. A small protrusion 193a is formed on the periphery of the pressing portion 193 (see FIG. 5). The small protrusion 193a is adapted to fit into a small hole 185a formed at the periphery of the fitting hole 185. This state is the temporary fastening state (see FIG. 6).

  Then, when the pressing member 193 is fitted into the fitting hole 185 by inserting the bridging member main body 190 through the lid-side sealing portion 165, the pressing member 193 is flush with the top plate 179a and the outer surface thereof. The thickness and diameter of the pressing portion 193, the depth and diameter of the fitting hole 185, and the length dimension of the bridging member 169 (length dimension of the bridging member main body 190) so that the state can be maintained. Is defined (see FIG. 6).

  In addition, a long groove 193b into which the tip of a driver (not shown) enters is formed on the surface of the pressing portion 193. When the bridging member 169 is viewed from above, the first engagement piece 191 is parallel to the elongated groove 193b, but the second engagement piece 192 is orthogonal (see FIGS. 4 and 8).

  The second engagement piece 192 is a rectangular bar that is orthogonal to the bridging member main body 190, and is larger than the fitting hole 185 of the lid side sealing portion 165, the diameter of the stepped through hole 182 o, and the rectangular through hole 188. Although it is short, it is longer than the diameters of the through holes 172o and 174o of the main body side sealing portion 166.

  When the bridging member 169 is pushed in while being rotated by a screwdriver or the like, the second engagement piece 192 is temporarily fixed to the oblong rectangular through hole 188 of the lid-side sealing portion 165 according to the rotation angle. It moves to both the position and the main fastening position. Therefore, the second engagement piece 192 has a size that can pass through the rectangular through hole 188 and has a shape similar to that of the through hole.

  The temporary fastening position with respect to the rectangular through hole 188 means that when the bridging member 169 is put in the lid side sealing portion 165, only the first engagement piece 191 passes through the rectangular through hole 188 and the second engagement is performed. The piece 192 is a position where the second engagement piece 192 crosses the rectangular through hole 188 without passing through the rectangular through hole 188. In this embodiment, for example, the second engagement piece 192 is in the second engagement with the rectangular through hole 188. This is where the joint piece 192 is in an orthogonal state.

  When the second engagement piece 192 crosses the rectangular through hole 188, the progress of the bridging member 169 is prevented and the bridging member 169 is retained on the lid-side sealing portion 165, so the second engagement piece 192 It can be said that it is an engagement piece for temporary fastening. In this embodiment, the small protrusion 193a of the pressing portion 193 is fitted into the small hole 185a formed on the periphery of the fitting hole 185 of the lid side storage body 179, indicating that the bridging member 169 is in the temporary fastening position. It can be visually recognized by being in a trapped state.

  Therefore, in a state where the pressing portion 193 is viewed from the axial direction of the bridging member 169 with the small protrusion 193a fitted in the small hole 185a, the second engagement piece 192 has the small protrusion of the pressing portion 193. It is formed so as to be orthogonal to the center line L1 of the pressing portion 193 passing through 193a (see FIGS. 4, 8, and 9). The small protrusion 193a is elastically deformed with the insertion of the pressing portion 193 and enters the space 179S (see FIG. 7). Thereafter, even if the bridging member 169 is taken out from the fitting hole 185, the small protrusion 193a becomes an obstacle. You won't get out of there. A plurality of small protrusions 193a may be provided.

  The center line L1 and the first engagement piece 191 are formed in parallel. The elongated groove 193b of the pressing portion 193 is formed so as to be on the center line L1 (see FIGS. 4, 8, and 9). For this reason, the 1st engagement piece 191 and the elongate groove | channel 193b are parallel. In addition, the direction of the small hole 185a in the lid side housing 179, in other words, the center line L2 of the fitting hole 185 including the small hole 185a and the rectangular through hole 188 are parallel to each other (see FIG. 4).

  The bottom plate portion 179b of the lid-side container 179 having the rectangular through hole 188 to be temporarily fastened is prevented from being advanced by the second engagement piece of the bridging member 169 to prevent the bridging member 169 from moving forward. This is referred to as a temporary fastening portion that is fastened to the lid side sealing portion 165.

  The main fastening position with respect to the rectangular through-hole 188 is a state in which the bridging member 169 cannot be pulled out from the main body side sealing portion 166 and the lid side sealing portion 165, that is, the main fastening state. Position (see FIGS. 7 and 10).

  In order to move the bridging member 169 from the temporary fastening position to the final fastening position, the bridging member 169 is rotated to release the state where the second engagement piece 192 intersects the rectangular through-hole 188, and the lid side sealing is performed. The second engagement piece 192 is passed through the rectangular through hole 188 in a non-crossing state with respect to the rectangular through hole 188 of the stopping portion 165, and then the bridging member 169 is snap-coupled by the main body side sealing portion 166. Thus, the first engagement piece 191 and the second engagement piece 192 of the bridging member 169 sandwich the ceiling wall surface 172 of the main body side box portion 167 and the top plate portion 168a of the main body side storage body 168.

  Thus, the main board 24 housed in the case main body 126 having the sealing portion 164 to which the control board sealing structure according to the present invention is applied has been replaced or the ROM 31 mounted on the main board 24 has been tampered with. When verifying that the main board 24 or the circuit components including the ROM 31 provided on the main board 24 is replaced, the top plate portion 179a of the lid side storage body 179 and the bottom plate portion 168b of the main body side storage body 168 are used. Is applied to the top plate portion 179a to bend and destroy the top plate portion 179a and the bottom plate portion 168b at the positions where the lid side folding groove 187 of the top plate portion 179a and the main body side folding groove 177 of the bottom plate portion 168b are formed. After opening the top plate portion 179a and the bottom plate portion 179b and removing the bridging member 169 from the openings, the lid side sealing portion 165 and the main body side sealing portion 166 By releasing the connection, the state in which the board storage port 126o of the case main body 126 in which the main board 24 is stored is sealed with the lid 125 is released, and the main board 24 stored in the case main body 126 can be replaced. After verifying that the ROM 31 mounted on the board 24 has not been tampered with, or after replacing the circuit board including the ROM 31 provided on the main board 24 or the main board 24, the lid side storage body 179 or the main body side storage With the body 168 renewed, the removed bridging member 169 or the new bridging member 169 is temporarily fastened to the lid-side sealing portion 165 and can be properly sealed by the temporary fastening. After confirming the above, the bridging member 169 is snap-coupled to the ceiling wall surface 172 of the main body side sealing portion 168 to thereby form the main body side sealing portion 166 and the lid side sealing portion 165. And the closure of the junction member 169 performs the sealing again. Thereafter, the substrate storage case 25 and the reel unit 26 are attached to the housing 11 in the reverse order to the case where the substrate storage case 25 is removed from the housing 11 and the upper door 12a of the pachinko slot 10 is closed. Ready for operation.

  Therefore, in the substrate storage case 25, it is possible to seal the lid that closes the storage opening of the case main body, which has been conventionally required, without using a one-way screw.

  In addition, when an external force is applied to the bottom plate portion 168b of the main body side storage body 168 and the top plate portion 179a of the lid side storage body 179, the bottom plate portion 168b and the top plate portion 179a are simplified by the main body side folding groove 177 and the lid side folding groove 187. Therefore, it can be seen that the bottom plate portion 168b and the top plate portion 179a have been destroyed and illegally acted by someone.

  When the substrate storage port 126o of the case main body 126 is covered with the lid 125, the main body side sealing portion 166 provided in the case main body 126 and the lid side sealing portion 165 provided in the lid 125 are combined portions thereof. Are joined by the bottom plate wall surface 182 of the lid side sealing portion 165 and the ceiling wall surface 172 of the main body side box portion 167 (the flat concave portion 174 of the main body side box portion 167 and the flat convex portion 184 of the lid side box portion 178 are press-fitted. The lid 125 cannot be detached from the case main body 126.

  Since the bridging member 169 has the first engagement piece 191 and the second engagement piece 192 that can permanently remove the bridging member 169 from the main body side sealing portion 166 and the lid side sealing portion 165, Even when the side sealing portion 166 and the lid side sealing portion 165 are disconnected and separated from each other, the bridging member 169 is not separated from the main body side sealing portion 166 and the lid side sealing portion 165. Then, the movement of the lid 125 is suppressed, and the board storage opening 126o cannot be sufficiently opened. Therefore, the main board 24 stored in the case main body 126 cannot be taken out from the board storage opening 126o or is taken out. It becomes difficult.

  In order to take out the main board 24 from the board storage port 126o, it is necessary to release the main fastening state of the bridging member 169. For this purpose, the bridging member 169 is forcibly cut or the first engagement piece 191 is removed. By deforming the first engagement piece 191 through the through hole 172o of the main body side box portion 167 and the through hole 174o of the main body side storage body 168, the main fastening is released and the main body side sealing portion is released. It is necessary to break the coupling between 166 and the lid-side sealing portion 165. When the bridging member 169 is cut or the first engagement piece 191 is deformed, the trace remains on the bridging member 169.

  On the other hand, the main board 24 stored in the case main body 126 is replaced, the verification that the ROM 31 mounted on the main board 24 is not falsified, or the circuit including the ROM 31 provided on the main board 24 or the main board 24. When a legitimate act is performed, such as when a component is replaced, even if the trace remains in the tail bridge member 169, it can be changed to a new bridge member 169. The possibility that a suspicion that the resulting fraud has been performed can be solved.

  Therefore, the state in which the bottom plate portion 168b and the top plate portion 179a are destroyed and the presence or absence of traces due to the cutting or deformation of the bridging member 169 are useful for determining whether or not an illegal act has been performed.

  In addition, the lid-side sealing portion 165 has a lid-side storage body 179 for temporarily fastening the bridging member 169 to the lid-side sealing portion 165 via the second engagement piece 192 before the main fastening. You can confirm the appropriateness before the main fastening. In this way, it is possible to confirm whether or not the sealing can be really performed before the main fastening, so that it is possible to effectively prevent the sealing from being performed erroneously. Further, in the temporarily fastened state, the pressing portion 193 is fitted in the fitting hole 185 so as to be flush with the outer surface of the top plate portion 179a, so that an external force acts positively on the pressing portion 193. As long as the board storage case is transported, it is not permanently fastened.

Note that the top plate portion 179a of the lid side storage body 179 and the bottom plate portion 168b of the main body side storage body 168 are bent by the lid side folding groove 187 and the main body side folding groove 177 in a state where the pachinko slot 10 is installed in the game hall. If it is determined that only when the verification or replacement is performed, the top plate portion 179a of the lid side storage body 179 or the bottom plate portion of the main body side storage body 168 is already in the bent state during the verification or replacement. If there is 168b, it is revealed that there has been an illegal act by somebody.
In addition, since the connection part 126a has the constriction 127, since it will be damaged if a load acts on the sealing part 164 abnormally, it can also be found out of an illegal act.

Further, since sealing is not performed using screwing means such as a one-way screw, the sealing can be released relatively easily.

  Furthermore, since the case body 126 including the main body side sealing portion 166 and the lid body 125 including the lid side sealing portion 165 are made of ABS resin which is a transparent material, the bridging member 169 includes the main body side sealing portion 166 and the lid. It is obvious at a glance that it is in the side sealing portion 165. Therefore, it is possible to determine whether or not an illegal act has been performed without releasing the seal.

  The second embodiment is different from the first embodiment in that the lid-side storage body 179 is not provided, and instead formed in the bottom plate portion 179b of the lid-side storage body 179 in the stepped through hole 182o of the bottom plate wall surface 182 of the lid-side box portion 178. A cap body 269 having a lid-side folding groove 187 is provided instead of the top plate portion 179a of the lid-side storage body 179, and the cap body 269 is provided. A cap body 268 having a main body side folding groove 177 is provided instead of the bottom plate portion 168b of the main body side storage body 168, and the main body side box is provided by the cap body 268. This is a point related to closing the opening 170 of the part 167 and a point related thereto. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As can be seen from FIGS. 11 to 14, the cap body 268 and the cap body 269 are externally fitted to the main body side box portion 167. However, it has a tight fit so that it cannot be removed without using a special tool.

  As can be seen from FIGS. 11 and 12, the through-hole 288 is a hole having an outer shape such that a rectangular cylinder is penetrated from the peripheral surface of the flat cylindrical shape. The rectangular angular space portion 288R corresponds to the rectangular through-hole 188 of the first embodiment, and when the second engagement piece 192 of the bridging member 169 enters in parallel to the longitudinal direction of the angular space portion 288R, this fastening is performed. When the second engaging piece 192 of the bridging member 169 crosses the longitudinal direction of the angular space portion 288R, it is temporarily fixed (see FIG. 15).

  Also in the case of Example 2, since it can be confirmed whether or not the seal can be really made by temporary fastening before the main fastening is performed, it is possible to effectively prevent erroneous sealing (see FIG. 2). 13, see FIG. In addition, the state in which the bottom plate portion 168b and the top plate portion 179a are destroyed and the trace of the bridging member 169 are useful for determining whether or not an illegal act has been performed.

  Further, since the cap body 268 provided with the main body side folding groove 177 and the cap body 269 provided with the lid side folding groove 187 are more compact than the main body side storage body 168 and the lid side storage body 179, management thereof is possible. It is easy and saves material.

Note that the present invention is not limited to the illustrated examples described above, and various modifications can be made without departing from the scope of the present invention. For example, if several types of bridging members 169 are prepared and different colors are used for each censorship, what color will be used for this verification is only for those involved. Because it is to know, this also helps to discriminate fraud.
