Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko machine provided with a control board configured using electronic components such as a central processing unit and a memory in order to control game contents.
[0002]
[Prior art]
The game content of a gaming machine such as a pachinko machine is controlled by a control board configured by arranging electronic components such as a central processing unit (CPU), a memory such as a ROM and a RAM on a printed circuit board. Since the open state of the special prize opening is regulated by law in order to reduce the betting ability, the game content is controlled according to this regulation. However, there is a risk that the control board may be modified by changing these electronic components or changing the circuit, and the gaming content may be changed to a highly gaming game. Therefore, a means for preventing or detecting such unauthorized modification. It is necessary to provide. Therefore, for example, Japanese Patent Publication No. 5-43820 discloses that a seal paper is attached to each desired electronic component and a printed circuit board case on which the electronic component is arranged, and the sealed state of each electronic component can be inspected. An invention is disclosed in which an observation means such as a window is provided in the case so that it can be discovered when the sealing paper is broken and modified.
[0003]
[Problems to be solved by the invention]
However, sealing with the above-mentioned sealing paper can be done without breaking the sealing paper with a special chemical even if it is sealed for each electronic component, or forgery, so it is easy to modify the control board after all In addition, this could not be found in the inspection, and the effect of preventing modification of the control board was weak.
[0004]
In view of the above, an object of the present invention is to provide a gaming machine that can effectively prevent modification of a control board and also reliably detect modification.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is a pachinko gaming machine comprising a control board for controlling game contents by arranging electronic components on a printed board, wherein the printed board is at least desired. The electronic component is covered with a transparent resin coating for preventing fraud together with the electronic component so that the electronic component cannot be replaced unless the resin coating around the electronic component is removed. Even if the resin coating is performed again around, the thickness of the joint between the original resin coating and the new resin coating becomes discontinuous, so that it is possible to discover that the coating has been performed again. Is.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view of a pachinko machine 1 as an example of a gaming machine viewed from the back side. A mechanism board 3 that is hinged to the machine frame 2 so as to be freely opened and closed is provided with a gaming board 4. On the back side, a control board group 6 such as a symbol display and a decorative lamp is installed in addition to a main board 5 for controlling main game contents such as an open state of a big prize opening. In addition, a prize ball tank 7 for storing game balls to be paid out at the time of winning a prize is provided above, and a prize ball payout device 8 is provided on the side thereof. Reference numeral 9 is a prize ball payout board, and 10 is a game ball launcher unit.
[0007]
FIG. 2 is an explanatory diagram of the main board 5. The main board 5 is arranged with electronic parts such as the CPU 12, memories 13, 13,... Such as ROM, RAM, and resistors 14, and other external boards and control parts. A printed circuit board 11 having a connector portion 15 of a connection terminal connected to the base plate 16 is screwed to a metal base 16 and further covered with a box-shaped cover 17 from above to be screwed to the base 16. . The cover 17 is made of a transparent synthetic resin, and on its inner surface, a metal reinforcement comprising two opposing side surface portions 19 and 19 and a lattice-shaped upper surface portion 20 integral with the side surface portions 19 and 19 is provided. A plate 18 is fitted. Reference numerals 17a, 17a,.
Then, on both the upper and lower surfaces of the printed board 11, as shown in FIG. 3A, transparent coating layers 21 and 21 made of epoxy resin are formed on almost the entire surface except for the connector portion 15. The coating layer 21 is formed by liquefying the epoxy resin with a solvent, spraying it on the surface, and solidifying it. In this state, the electronic parts such as the CPU 12 and the memory 13 and the surrounding printed circuit board 11 are formed. The outer surface is completely covered so that the electronic parts cannot be directly touched by hand.
[0008]
Therefore, in the main substrate 5 configured as described above, when the IC such as the CPU 12 or the memory 13 is replaced, for example, the coating layer 21 around the corresponding electronic component must be removed as shown in FIG. Therefore, it takes a lot of time to change parts and change the circuit, which leads to prevention of unauthorized modification. In particular, since the coating layers 21 are formed on both surfaces of the printed circuit board 11, the removal of components becomes more troublesome and the effect of preventing unauthorized modification is further enhanced. In this way, when the tampering is performed in this way, the coating layer 21 can be easily confirmed by being removed at the place of the replaced electronic component 13a, so that the inspection can be performed quickly. Further, even if the remodeler performs resin coating again after unauthorized modification, the original coating layer 21 and the new coating layer 22 are not naturally connected as shown in FIG. In this case, the modification can be easily found. Thus, the illegal modification can be easily found, and the effect of preventing the illegal modification is further enhanced.
[0009]
This coating layer is not formed on the entire surface of the printed circuit board. For example, only important ICs such as CPU, ROM and RAM are selected, and a desired electronic component is selected and resin coating is applied only to that portion. May be. In this case, for example, masking can be performed simply by masking parts other than the selected electronic component, spraying an epoxy resin or the like, and then removing the masking. Also, the coating layer can be formed only on one side of the electronic component, not on both sides of the printed circuit board, or the thickness of the coating layer can be changed according to the type of electronic component. Further, in the above embodiment, the resin coating is performed only on the main board that performs important control of the game content, but the prize ball payout board 9 and the arbitrary board in the board group 6 described above are not the main board. A resin coating may be similarly applied to a desired control substrate. Other resin types and coating layer forming methods are not limited to the above-mentioned forms. For example, vinyl chloride, vinyl acetate, other resin adhesives are used as the resin type, and immersion methods are used as the coating layer forming method. The method can be appropriately changed without departing from the spirit of the present invention, such as adopting a law.
[0010]
【The invention's effect】
According to the present invention, since the printed circuit board is covered with at least a desired electronic component and the resin coating, it is difficult to replace the component and change the circuit, which is effective in preventing unauthorized modification. In addition, even if remodeling is performed, it can be detected immediately in the state of the resin coating, so that the inspection becomes easy, and this also prevents unauthorized modification.
