The winning device and the display device are controlled by a logic control circuit board on which a large number of electronic components such as ICs and LSIs are mounted, or a control circuit board on which a microcomputer is mounted. Encased and stored in a board box with a cover.

  By the way, in recent years, an illegal act of changing the game content of a gaming machine by removing and replacing the ROM storing the control information related to the game content from the control circuit board housed in the board box has become a problem. On the other hand, as a countermeasure against such illegal acts, a control circuit housed in a board box is sealed by sealing the board box using a board box sealing tool or the like described in Japanese Patent Application No. 9-110700 (unknown). There has been proposed a method for preventing an illegal act of changing a game content by removing and replacing a ROM from a board.

  This board box sealing tool mainly includes a pair of sealing members respectively disposed on the box base and the box cover, and a special sealing screw for connecting the pair of sealing members. One of the pair of sealing members is embedded with a nut member that holds the sealing screw in a state where it cannot be removed, and the pair of sealing members are brought into contact with each other while being opposed to each other, and the sealing screw is screwed into the nut member. Thus, the pair of sealing members are connected by the sealing screw, and the substrate box is sealed.

  However, in this substrate box sealing tool, the contact surfaces (opposite surfaces) of the pair of sealing members are formed in a substantially flat shape, and the nut member that holds the sealing screw so that it cannot be removed is press-fitted into one sealing member. Is buried. For this reason, the board box is opened by inserting a thin plate-like tool or the like between the contact surfaces of the pair of sealing members connected by the sealing screw and pulling the sealing screw together with the nut member from the sealing member. There was a problem. Therefore, there has been a problem that it is not possible to prevent an illegal act of changing the game contents by removing and replacing the ROM from the control circuit board housed in the board box.

The depth of the fitting hole 21a, that is, the length from the top surface of the sealing member 21 to the bottom surface of the fitting hole 21a is formed to be substantially the same as the thickness (axial length) of the nut head 12a of the nut 12. ing. Therefore, it is possible to prevent the upper end portion of the nut 12 fitted in the fitting hole 21 a from protruding from the upper surface of the sealing member 21. Therefore, when the box lid 3 is slid with respect to the box body 2 (in the direction of the arrow in FIG. 2), the lower surface portion of the sealing member 31 is prevented from being caught by the upper end portion of the nut 12, so 3 can be smoothly slid to match the sealing members 21 and 31.

  The fitting hole 21b is formed so as to communicate with the fitting hole 21a, and is formed so that the cylindrical portion 12b of the nut 12 can be fitted. The depth of the fitting hole 21b, that is, the length from the bottom surface of the fitting hole 21a to the bottom surface of the fitting hole 21b is formed larger than the axial length of the cylindrical portion 12b of the nut 12, and the cylindrical portion 12b. A space for holding the stopper member 13 can be formed between the lower surface of the first member and the bottom surface of the fitting hole 21b. Further, a chamfered portion C is formed at a connecting portion between the fitting hole 21b and the fitting hole 21c, and the receiving portion 13a of the stopper member 13 is fitted. Therefore, the stopper member 13 is positioned on the bottom surface of the fitting hole 21b through the chamfered portion C and is not pressed by the lower surface of the cylindrical portion 12b of the nut 12. Therefore, the tip end portion 11c of the sealing screw 11 can be easily inserted into the inner hole 13b of the stopper member 13, and the stopper member 13 can be easily elastically deformed.

  The fitting hole 21c is formed so as to communicate with the fitting hole 21b, and is formed so that the tip end portion 11c of the sealing screw 11 can be fitted. The depth of the fitting hole 21c, that is, the length from the bottom surface of the fitting hole 21b to the bottom surface of the fitting hole 21c is formed to be larger than the axial length of the tip portion 11c of the sealing screw 11. The bottom surface of the end portion 11c of the sealing screw 11 is not brought into contact with the bottom surface of the hole 21c.

Therefore, the male screw portion 11d of the sealing screw 11 can be inserted through the insertion hole 31b and screwed into the female screw portion 12c of the nut 12. Further, when the locking groove 11f of the sealing screw 11 is locked by the stopper member 13 and the sealing screw 11 is held in the sealing member 21 in a non-removable state, the head 11b of the sealing screw 11 has an engagement hole. It is engaged in 31a. Accordingly, the sealing members 21 and 31 are connected by the sealing screw 11 so as not to be separated, and the substrate box 1 can be sealed in a state where it cannot be opened.

  As shown in FIG. 5, when the sealing members 21, 31 are matched while facing each other and connected by the sealing screw 11, the peripheral wall 24 protruding from the upper surface portion of the sealing member 21 is recessed in the lower surface portion of the sealing member 31. The peripheral wall 34, which is fitted in the provided fitting groove 35 and protruded from the lower surface portion of the sealing member 31, is fitted into the fitting groove 25 which is recessed in the upper surface portion of the sealing member 21. Therefore, it is thin plate-shaped between the contact surfaces of the sealing members 21 and 31, that is, between the contact surfaces of the peripheral wall 24 and the fitting groove 35, or between the contact surfaces of the peripheral wall 34 and the fitting groove 25. Even when trying to open the substrate box 1 by pulling out the sealing screw 11 together with the nut 12 and the stopper member 13 to open the substrate box 1, the tip portion of the thin plate-shaped tool or the like is the peripheral wall 24, 34 or the fitting groove 25. , 35, the insertion can be prevented.

Then, the engagement frames 2d1 and the engagement claws 3d1 are engaged with each other so that the opening surfaces of the box body 2 and the box lid body 3 are matched with each other, and the box lid body 3 with respect to the bottom plate 2a of the box body 2 is obtained. The box lid 3 is placed over the box body 2 while the top plate 3a is opposed.

  When the box lid 3 is slid in the direction of the arrow in FIG. 2 or 5 after the box lid 3 is covered, the lock plates 2f and 3f are inserted into the insertion ports 3h and 2h of the engagement plates 3g and 2g, respectively. The plates 2f and 3f and the engaging plates 3g and 2g are engaged to couple the box body 2 and the box lid 3 together. On the other hand, when the box lid 3 is slid in the direction of the arrow in FIG. 2 or 5, the peripheral wall 24 protruding from the upper surface portion of the sealing member 21 is fitted into the fitting groove recessed in the lower surface portion of the sealing member 31. 35, the peripheral wall 34 protruding from the lower surface portion of the sealing member 31 is inserted into the fitting groove 25 recessed in the upper surface portion of the sealing member 21, and the sealing members 21, 31 are matched. .

  According to the sealing members 21, 31 matched in this way, between the contact surfaces (opposing surfaces), that is, between the contact surfaces of the peripheral wall 24 and the fitting groove 35, or the peripheral wall 34. Even if a thin plate-like tool or the like is inserted between the contact surfaces with the groove 25 and the sealing screw 11 is pulled out from the sealing member 21 together with the nut 12 and the stopper member 13, the tip of the thin plate-like tool or the like is opened. Since the portion is caught by the peripheral walls 24 and 34 or the fitting grooves 25 and 35, the insertion thereof is prevented. On the other hand, when the sealing members 21, 31 are matched, each spare screw holding plate 33 is provided above the head 11 b of each spare screw 111 held by each spare screw holding member 23.

  When the box body 2 and the box lid 3 are coupled and the sealing members 21 and 31 are matched, the through holes 3e1 formed in the box lid 3 and the screw holes 5a recessed in the partition plate 5 are provided. And match with each other. Thereafter, a wood screw or the like is screwed into each screw hole 5a of the partition plate 5 through each through hole 3e1 so as to straddle the box main body 2, the lock plates 2f and 3f, the engagement plates 3g and 2g, and the respective recesses 3e of the box lid 3. Then, a seal seal is affixed to each recess 3 e of the box lid 3.

  Next, among the sealing members 31 of the box sealing devices 10, the sealing member 31 disposed on the rearmost side of the side wall 3 b of the box lid body 3 and the frontmost side of the side wall 3 c of the box lid body 3 are disposed. The distal end portion 11c of the sealing screw 11 is inserted into each insertion hole 31b of the sealing member 31 thus formed. After inserting the sealing screw 11, a screw driver such as a screw driver is engaged with the engaging groove 11 g of the sealing screw 11, and the sealing screw 11 is screwed into the nut 12. When the sealing screw 11 is screwed in, the male screw portion 11 d of the sealing screw 11 is screwed into the female screw portion 12 c of the nut 12. When the screwing of the sealing screw 11 is continued, the tip end portion 11c of the sealing screw 11 reaches the receiving portion 13a of the stopper member 13 disposed below the nut 12, and is guided to the inner hole 13b. When the front end portion 11c of the sealing screw 11 is guided and inserted into the inner hole 13b, the inner hole 13a of the stopper member 13 is expanded by the tapered portion T1 of the front end portion 11c, and the receiving portion 13a of the stopper member 13 is elastically deformed.

Can be. Further, since the head 11b of the sealing screw 11 is engaged with the engagement hole 31a of the sealing member 31, the box body 2 and the box lid 3 of the substrate box 1 are connected so as not to be opened, and the substrate box 1 can be securely sealed (see FIG. 5). Therefore, an illegal act of illegally removing the control ROM of the control circuit board 4 encapsulated in the board box 1 and changing the game content of the pachinko machine 50 can be prevented. Further, if the sealing members 21 and 31 are broken, cut or the like, the substrate box 1 can be opened, but in that case, a trace of the opening of the substrate box 1 can be reliably left. That is, it is possible to immediately discover whether or not an illegal act has been performed.

  In addition, when the board box 1 is sealed in this way, each spare screw 111 held in each spare screw holding hole 23a is securely locked by each spare screw holding plate 33, and each spare screw holding hole is 23a is held in a state where it cannot be extracted. Therefore, the spare screw 111 is prevented from falling out of the spare screw holding hole 23a, and thus the spare screw 111 can be prevented from being lost. In addition, unauthorized removal of the auxiliary screw 111 can be prevented.

  Thus, according to the box sealing device 10 of the present embodiment, the peripheral walls 24 and 34 are provided on the outer periphery of the contact surfaces (opposing surfaces) of the sealing members 21 and 31 connected by the sealing screw 11, and The fitting grooves 25 and 35 formed in conformity with the peripheral walls 34 and 24 are recessed. Therefore, it is thin plate-shaped between the contact surfaces of the sealing members 21 and 31, that is, between the contact surfaces of the peripheral wall 24 and the fitting groove 35, or between the contact surfaces of the peripheral wall 34 and the fitting groove 25. Even when trying to open the substrate box 1 by pulling out the sealing screw 11 together with the nut 12 and the stopper member 13 to open the substrate box 1, the tip portion of the thin plate-shaped tool or the like is the peripheral wall 24, 34 or the fitting groove 25. , 35, the insertion can be prevented. Therefore, it is possible to prevent the board box 1 from being opened, and to prevent an illegal act of changing the game content of the pachinko machine 50 by removing and replacing the ROM or the like from the control circuit board 4 housed in the board box 1.

  FIG. 7 is a partial cross-sectional side view of the box sealer 110 of the second embodiment, and the arrows in the figure indicate the sliding direction of the box lid 3. The box sealing device 110 of the second embodiment is obtained by changing the shape of the contact surface of the sealing members 21 and 31 with respect to the box sealing device 10 of the first embodiment described above. In the following, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only different parts will be described.

  On the contact surfaces (opposing surfaces) of the sealing members 21 and 31 of the box sealing device 10 of the first embodiment, the peripheral walls 24 and 34 are provided so as to be fitted to the peripheral walls 34 and 24. The joint grooves 25 and 35 were recessed. However, in the box sealing device 110 of the second embodiment, as shown in FIG. 7, an inclined surface portion 124 inclined downward is formed on the right side edge portion of the upper surface of the sealing member 21, and the lower surface of the sealing member 31. An inclined surface portion 134 inclined downward toward the outer side is formed on the right edge portion so as to conform to the inclined surface portion 124 of the sealing member 21.

  By forming the contact surfaces (opposing surfaces) of the sealing members 21 and 31 as described above, when the box sealing tool 110 is pry open using a thin plate-like tool or the like, the thin plate-like tool or the like is inclined on the inclined surface portions 124 and 134. It is necessary to incline along and insert. In this case, the tip portion of the thin plate-like tool or the like is caught on the horizontal contact surface of the sealing members 21 and 31 and cannot be inserted deeply. Therefore, a thin plate-like tool or the like is inserted between the contact surfaces of the sealing members 21 and 31, the sealing screw 11 is pulled out from the sealing member 21 together with the nut 12 and the stopper member 13, and the substrate box 1 cannot be opened. A ROM or the like is removed from the control circuit board 4 housed in the box 1 and replaced to prevent an illegal act of changing the game content of the pachinko machine 50.

  FIG. 8 is a partial front sectional view of the box sealing device 210 of the third embodiment. In the box sealing device 210 of the third embodiment, the shape of the contact surface of the sealing members 21 and 31 is first changed with respect to the box sealing device 10 of the first embodiment described above. That is, in the first embodiment, the peripheral surfaces 24 and 34 are projected on the contact surfaces of the sealing members 21 and 31, and the fitting grooves 25 and 35 formed to fit the peripheral walls 34 and 24 are provided. It was recessed. However, in the third embodiment, as shown in FIG. 8, the contact surfaces 211 and 311 of the sealing members 21 and 31 are each formed in a sawtooth shape. The contact surfaces 211 and 311 are formed so as to be able to engage with each other, and are formed to be slidable in the front-rear direction of FIG. 8, that is, in the direction perpendicular to the paper surface of FIG. Therefore, in order to match the sealing members 21 and 31, the box lid 3 can be slid in the front-rear direction of FIG.

  Thus, by forming the contact surfaces 211 and 311 of the sealing members 21 and 31 in a sawtooth shape, a thin plate-like tool or the like is inserted between the contact surfaces 211 and 311 and sealed by the box sealing tool 210. Even if the substrate box 1 is to be opened and opened, a thin plate-like tool or the like is caught on the contact surfaces 211 and 311 formed in a sawtooth shape, and insertion thereof can be prevented.

  In addition, when cutting the sealing screw 11 that connects the sealing members 21 and 31 using a tool such as a saw to open the substrate box 1, the vicinity of the contact surfaces 211 and 311 of the sealing members 21 and 31 must be cut. I must. Therefore, when a person who has committed fraud conceals the fraud, it is necessary to apply an adhesive or the like to the cut portions to restore the sawtooth shapes of the contact surfaces 211 and 311. However, it is not easy to restore the saw-tooth contact surfaces 211 and 311 to conceal the trace of cutting, and it is not possible to reliably conceal fraud. , Such fraud can be suppressed.

  Moreover, the sealing members 21 and 31 facing each other of the box sealing tool 210 are colored in different colors. By the way, when the sealing box 11 that connects the sealing members 21 and 31 is cut with a tool such as a saw to open the substrate box 1, the vicinity of the contact surfaces 211 and 311 between the sealing member 21 and the sealing member 31 is cut. However, since the sealing members 21 and 31 are colored differently from each other, in order to repair the cut portion of the box seal 210 using an adhesive or the like and conceal the cut, the cutting member It is necessary to reproduce the color of the part. However, it is difficult to reproduce the color of the cut portion, and it is not easy to hide the cut trace. Therefore, since the fraudulent act cannot be reliably concealed, the fraudulent act can be detected at an early stage, and the fraudulent act can be suppressed.

  In addition, as a coloring pattern of the box sealing tool 210, the colors of the sealing members 21 and 31 facing each other may be different. For example, all the sealing members 21 of the sealing unit 20 are set to one color (for example, red). It is also possible to color all of the sealing members 31 of the sealing unit 30 facing the sealing unit 20 to another color (for example, green). Further, the four sealing members 21 of the sealing unit 20 are colored in different colors, for example, red, blue, yellow, and green, and the sealing member 31 facing the red sealing member 21 is green and blue sealing member 21. The sealing member 31 facing the yellow sealing member 21 may be colored in yellow, the sealing member 31 facing the yellow sealing member 21 in blue, and the sealing member 31 facing the green sealing member 21 in red.

  Further, in the box sealing device 210 of the third embodiment, wire members 212 and 312 made of wire material or the like are provided around the outer peripheral surface (outer periphery) of the sealing member 21 and the sealing member 31 in a lattice shape at substantially equal intervals. Therefore, when the box sealing tool 210 is cut using a tool such as a saw to open the substrate box 1, the teeth of the tool such as the saw are caught on the wire member 212 or the wire member 312. Therefore, when cutting with a tool such as a saw is performed, each part of the sealing members 21 and 31 other than the cutting part is broken by the wire members 212 and 312, and a trace of cutting can be left. It is not easy to repair the sealing members 21 and 31 destroyed in this way and conceal the traces of cutting, and it is impossible to reliably conceal fraud. Therefore, it is possible to detect an illegal act at an early stage and to suppress the illegal act.
