Conventionally, as a base case for this type of gaming machine, a control base having a ROM or the like storing a program for controlling a game is fixed to the gaming machine in order to prevent damage caused by a collision of a pachinko ball or a medal. And a case cover that covers the case body.
[0003]
In general, gaming machines such as pachinko machines and slot machines control game operations such as winning probabilities, the number of winning balls and payout medals, etc., based on a control board having a ROM that stores programs for controlling games. ing. The contents of the program stored in the ROM greatly influence the profit of the player and the profit of the game machine store. Therefore, the program stored in the ROM is one prepared by a gaming machine manufacturer so that the game content is such that the game content does not detract from the player's happiness.
[0004]
In addition, after installing the game shop, the regular ROM attached to the control board was illegally modified in order to remarkably increase the player's gambling feeling as the game content that was significantly free from the game content originally intended by the manufacturer. In order to prevent illegal acts that continue to be replaced with ROM, and to prevent this illegal action, the case cover is screwed and fixed to the case body to prevent the case cover from being opened unnecessarily. A seal is put in place between the case body and the case cover so that the fact that the case cover has been opened is obvious so that the ROM cannot be replaced with an illegally modified ROM that cannot be distinguished. The fact that the case cover was removed made it possible to see the fact that the case cover was opened.

[Problems to be solved by the invention]
However, in the base case for the conventional gaming machine described above, the case cover is simply screwed and fixed to the case body, so remove the screw with a tool such as a screwdriver and skillfully peel off the seal. After performing illegal modifications such as replacing the ROM, there was a problem that clever fraud was still performed, such as fixing the case cover again with screws and sticking the seal back to the original. .
[0006]
In order to prevent this skillful fraud, once the case cover is closed, the case cover cannot be opened again unless the case is destroyed. However, it is possible to inspect whether the control base of the gaming machine installed at the amusement store is legitimate or not in the state where it is installed at the amusement store or to repair the control base due to an inevitable failure. In this case, once the base case is destroyed, it will not be possible to keep the base case in the closed state, and it will not be possible to effectively prevent subsequent unauthorized modifications. There was a problem.
[0007]
Although a method of replacing the base case with a new one is also considered, there has been a problem that it is not practical because it takes too much time and cost when inspection and repair are performed multiple times.
Accordingly, the base case for a gaming machine according to claim 1 has been made in view of the above-described problems of the prior art, and its purpose is to illegally modify the control base with a simple structure. The case cover can be easily opened for inspections and repairs, and the case cover can be fixed to the case body again so that unauthorized modification of the base is impossible. It is intended to provide a base case for gaming machines.

[0025]
As shown in FIGS. 1 and 2, the case cover 30 has a pair of right and left fixing portions 70 for fixing the case cover 30 to the case body 20 on the left and right side portions of the case cover 30. Four sets are provided along a side portion with a predetermined interval. The four pairs of left and right fixed portions 70 are respectively arranged corresponding to the mounting portions 50 of the case body 20, and are provided so as to protrude from the side surface of the case cover 30 in the left-right direction. Since the left and right set of fixing portions 70 are also formed symmetrically, like the mounting portion 50 of the case body 20, the set of fixing portions 70 is the same unless otherwise specified. Only the left fixing portion 70 corresponding to the left mounting portion 50 will be described.
[0026]
As shown in FIG. 2, the left fixed portion 70 is opposed to each other with a predetermined facing interval, and has two breakage portions 71 projecting outward from the side surface of the case cover 30, and the tip of the breakage portion 71. And a head cover 72 having a cylindrical shape. The two broken portions 71 are formed to have a width that can be cut using a simple tool such as a nipper. Moreover, it arrange | positions through the predetermined facing space | interval so that the front-end | tip of cutting tools, such as a nipper, may be easy to insert. The method of breaking may be any method, but for easy cutting, preferably a method of inserting the tip of the cutting tool into the opposing interval formed between the two breaking portions 71 Is good. Further, if the break portion 71 is formed so as to be capable of being cut, it is damaged by receiving an external pressure other than for cutting. Therefore, the break portion 71 can be cut, and the head cover 72 is attached to the two covers. By being supported by the rupture portion 71, the rupture portion 71 is configured so as not to be easily ruptured except for rupture using a tool.
[0027]
As shown in FIGS. 9 and 10, a fixing hole 73 into which a screw 60 can be screwed is formed at the bottom of the head cover 72 so as to correspond to the mounting hole 51 of the mounting part 50. Then, by screwing the screw 60 from the fixing hole 73 into the mounting hole 51 of the mounting portion 50 and tightening, the left mounting portion 50 can be fixed to the left fixing portion 70 in the corresponding position. The case cover 30 can be fixed to the case body 20. Note that the case cover 30 can be fixed to the case body 20 by fixing the left mounting part 50 to the corresponding left fixing part 70. The right mounting portion 50 may be fixed to the right fixing portion 70 disposed at the corresponding position.
[0028]
The head cover 72 has an inner diameter slightly larger than the outer diameter of the screw head 61 as shown in FIGS. 9 and 10 so that the screw 60 can be screwed. The difference between the outer diameter and the inner diameter of the head cover 72 is formed so as to have only such a difference that a tool such as pliers is not inserted. Therefore, as shown in FIG. 10, when the screw 60 is screwed up to the screw head 61, the screw head 61 is pinched by a tool such as pliers and the screw head 61 is forcibly pushed in the anti-screwing direction (counterclockwise). ) To loosen the screw 60.
[0029]
Therefore, since the screw 60 screwed into the fixing hole 73 from the mounting hole 51 cannot loosen the screw 60, in order to remove the case cover 30 from the case body 20, it is necessary to break the two breaking portions 71 There is. When the two breaking portions 71 are broken, the mounting portion 50 is fixed to the fixing portion 70 with screws, and the fixing portion 70 is continuous with the case cover 30 only by the breaking portion 71. The fixing part 70 can be detached from the case cover 30 by the breakage of the two breaking parts 71. If the case cover 30 is pulled away from the case main body 20 in this manner, the fixing part 70 screwed to the attachment part 50 is secured. Can be detached from the two broken portions 71 and remain on the attachment portion 50, and the case cover 30 can be removed from the case body 20.
[0030]
In order to fix the case cover 30 to the case body 20 again after removing the case cover 30 from the case body 20, another pair of left and right mounting parts 50, which are not yet broken, A fixing unit 70 may be used. The depth of the head cover 72 of the fixing portion 70 is such that the screw head 61 does not protrude from the upper end of the head cover 72 even when the screw 60 is screwed only into the fixing hole 73 and temporarily fixed. Is equipped.
[0031]
Therefore, even when the case cover 30 is not yet fixed to the case body 20 and the screw 60 is screwed only into the fixing hole 73 and temporarily fixed, the screw 60 does not hit other things, for example, The screw 60 can be temporarily fixed during transportation. In addition, when fixed using a pair of left and right mounting portions 50 and fixing portions 70, each of the other pair of left and right mounting portions 50 and fixing portions 70 that are not used is also fixed. By screwing the screw 60 only into the hole 73, the screw 60 can be temporarily fixed.
[0032]
Therefore, when fixing the case cover 30 to the case main body 20, the screw 60 prepared separately is not lost or removed from another package, so that quick work is possible and at the time of transportation. Does not require separate packaging. Further, a pair of claw receiving portions 32 corresponding to the pair of claw portions 23 of the case main body 20 into which the pair of claw portions 23 are respectively fitted are formed above the left and right sides of the case cover 30. The pair of claw receiving portions 32 are fitted upwards with the locking holes 31 of the case cover 30 fitted into the locking portions 24 of the case body 20 and the case cover 30 as the fulcrum. If it is raised and the opening of the case body 20 is closed as it is, a hole 33 into which the pair of claws 23 are fitted from below is formed.
[0033]
Therefore, in a state where the pair of claw portions 23 are fitted in the pair of claw receiving portions 32, the engagement portion is fitted in the engagement hole, and the engagement portion has an L-shaped cross section with a short side facing downward. Therefore, the case cover 30 cannot be removed from the case body 20 unless the claw 23 fitted in the claw receiving portion 32 is removed. Next, a procedure for fixing the case cover 30 to the case main body 20 fixed to the back side of the game board 40 and containing the control base B using the base case 10 having the above configuration, the case main body 20 with the case cover 30 A procedure for removing the case cover 30 from a state in which the case cover is fixed and a procedure for fixing the case cover 30 to the case body 20 again will be described.
[0034]

In order to attach the case cover 30 to the case body 20, first, as shown in FIG. 5, the case cover 30 is separated from the case body 20 and the case cover 30 as shown in FIGS. The respective locking holes 31 are inserted into the respective locking portions 24 of the case body 20, and the claw receiving portions 32 of the case cover 30 are fitted into the claw portions 23 of the case body 20. In this state, the claw portion 23 is fitted in the claw receiving portion 32, so that the case cover 30 remains in the case body 20 even if the hand is released from the case body 20 during the operation of fixing the case cover 30 to the case body 20. Therefore, the fixing work can be performed efficiently. Further, when the nail 23 is fitted into the nail holder 32, it is necessary to deform the nail holder 32 slightly outward as shown in FIG. 6 and then fit the nail 23 into the hole of the nail holder 32. Therefore, in order to remove the claw part 23 from the claw receiving part 32, the case cover 30 must be deformed to the outside again, so that the case cover 30 can be easily detached from the case body 20 even with temporary fixing. There is no such thing.
[0035]
Next, in the state where the case cover 30 is temporarily fixed to the case body 20, as shown in FIG. 9, the screw 60 temporarily fixed in the fixing hole 73 of the fixing portion 70 is further screwed, and the screw 60 is set in FIG. As shown in FIG. 10, it is inserted into the mounting hole 51 of the mounting portion 50 and fixed. Since the screw 60 screwed into the mounting hole 51 of the mounting portion 50 is formed so that it can be screwed only in the screwing direction as described above, the screw 60 can be loosened using a screwing tool such as a screwdriver. I can't. Also, the screw 60 screwed into the mounting hole 51 is covered with the head cover 72 to the upper end of the screw head 61, so the screw head 61 is not pinched by a tool that sandwiches the screw head 61 such as pliers, As a result, the screw 60 cannot be loosened.
[0036]
Therefore, the case cover 30 cannot be removed from the case body 20 by loosening the screw 60. Next, in order to remove the case cover 30 from the case main body 20, as shown in FIG. 11, the two breaking portions 71 of the fixing portion 70 are broken using a cutting tool such as a nipper. Each rupture portion 71 is formed to have a width that can be easily broken by a cutting tool such as a nipper, and the two rupture portions 71 are arranged at a predetermined distance from each other. Is easy to insert.
[0037]
Further, since the fixing portion 70 is continuous only with the case cover 30 and the two broken portions 71, the fixing portion 70 and the case cover 30 can be detached when the two broken portions 71 are cut. Therefore, when the case cover 30 is pulled in the direction of separating from the case main body 20, the case cover 30 can be removed from the case main body 20, as shown in FIG.
[0038]
As described above, in order to remove the case cover 30 from the case body 20, the two broken portions 71 of the fixing portion 70 must be broken, and therefore the case cover 30 cannot be easily opened, The cover 30 cannot be opened freely to modify the control board B or to replace the ROM storing the program. In addition, when the case cover 30 is opened for reasons other than normal repairs or inspections, it is immediately revealed that the case cover 30 has been opened improperly because it becomes a trace of opening when the broken portion 71 breaks.
[0039]
Next, after removing the case cover 30 from the case main body 20 and repairing or inspecting the control board B, in order to fix the case cover 30 to the case main body 20 again, the two broken portions 71 are first provided. Since the pair of left and right fixed portions 70 and the mounting portion 50 that are broken cannot be used, the following set of fixing portions 70 and the mounting portion 50 are used in the manner described above, The mounting portion 50 and the fixing portion 70 may be fixed with screws.
[0040]
In the example of the present embodiment, since each pair of the attachment portion 50 and the fixing portion 70 is provided in four sets in total, the case cover 30 is reattached to the case body 20 three times except for the first fixing. Can be fixed. Further, the operation of removing the case cover 30 and fixing it again to the case body 20 from the state in which the case cover 30 is first fixed to the case body 20 can be performed three times in total.
[0041]
In addition, if the fact that the case cover 30 was opened for repair or inspection was recorded, it was found that the case cover 30 was opened improperly if there was a fact that the broken portion 71 was not recorded. And convenient. In addition, since the pair of left and right mounting portions 50 and the fixing portion 70 are provided, a pair that is not broken even if the case cover 30 is removed from the case body 20 by breaking the two broken portions 71. The case cover 30 can be fixed to the case body 20 again by using the pair of left and right mounting portions 50 and the fixing portion 70, which is extremely economical.
