Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a plurality of electronic components are classified by function, data for controlling each electronic component is recorded for each function, and a plurality of terminals exposed from an integrated circuit capable of rewriting the data contents The present invention relates to a gaming machine including an integrated circuit mounting control board bonded at a predetermined position.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, in gaming machines such as pachinko machines, a special gaming value can be obtained by electronic control. A control board on which a central processing unit (CPU), a storage element (for example, ROM) and the like, which are hardware for electronic control, is mounted is protected from contact with the outside, impact, and the like together with other electronic components. Covered by a removable protective cover.
[0003]
The ROM as the storage element stores the program for the electronic control, data necessary for the operation of the program, etc., and the ROM of the ROM is used for analyzing the operation of the control board and performing fraud such as copying. It is necessary to analyze the internal data.
[0004]
In addition to the ROM, a programmable logic device (PLD) has attracted attention as an element capable of freely programming hardware logic connections. If ROM and PLD are used together, even if the internal data of ROM is analyzed, if the internal circuit of PLD is not known, the operation of the control board cannot be recognized, and the control board can be analyzed for illegal purposes. It becomes difficult.
[0005]
On the other hand, if the PLD is used after performing a proper procedure, the program and data inside the PLD can be rewritten, so that the control board can be applied to another game machine without replacing the surrounding electronic components. Become.
[0006]
By using this PLD, it is possible to apply the control board to another game machine by simply rewriting the internal program, data, etc., without replacing the surrounding electronic components. That is, it is excellent in versatility and can contribute to the reduction of industrial waste that has become a problem in recent years.
[0007]
However, when PLD is used, not only unauthorized modification such as replacement of PLD itself, but also electrical operation through a part of terminals exposed from PLD can be made, and internal programs and data can be altered. There is sex.
[0008]
In consideration of the above facts, the present invention provides an integrated circuit mounting control board that can be mounted on a control board in a state where it is impossible to tamper with internal data, etc., as well as to exchange integrated circuits such as PLDs. The purpose is to obtain a gaming machine provided .
[0009]
[Means for Solving the Problems]
The present invention relates to an integrated circuit in which a plurality of electronic components are classified by function, data for controlling each electronic component is recorded for each function, and the data contents can be rewritten , and the integrated circuit. In a gaming machine provided with a control board in which a plurality of exposed terminals are bonded at predetermined positions, it always includes terminals for inputting and outputting data stored in the integrated circuit, and is recorded in the integrated circuit. In addition, a plurality of terminals exposed from the integrated circuit are covered with a member that leaves a trace when the integrated circuit is peeled off, excluding the data check terminals .
[0011]
According to the present invention, among a plurality of terminals of an integrated circuit, for example, a part including an input / output terminal for internal program data, parameter data, etc. is selected as being included, and a part of the terminal is covered. The This ensures that, falsification of such data easily becomes impossible. In addition, since the trace of the member to be covered remains when it is peeled off, it can be easily found by visual inspection if unauthorized modification is performed.
[0014]
Among the plurality of terminals of the integrated circuit, for example, to select the terminal for checking such internal program data and parameter data be excluded terminal, you covered except for a part of the terminal. This ensures that it is possible to check such data easily, and falsification becomes impossible. In addition, since the trace of the member to be covered remains when it is peeled off, it can be easily found by visual inspection if unauthorized modification is performed.
[0015]
In the present invention, there is provided a socket provided between the integrated circuit and the control board, comprising a sub-terminal equivalent to the integrated circuit, the sub-terminal being joined to the control board, and the integrated circuit being removable. The socket and the integrated circuit are managed by a predetermined identification code.
[0016]
Normally , the integrated circuit is not directly bonded (for example, soldered) to the control board, but a socket provided with a terminal (sub-terminal) equivalent to the integrated circuit is bonded to a predetermined position on the control board. An integrated circuit may be removably attached. In such a case, it is contrary to the advantage of improving work efficiency that it is easy to attach and detach, and unauthorized exchange becomes possible.
[0017]
Therefore, for example, by covering only a part of the terminals, or covering the entire socket except for some other terminals, it is possible to establish fraud prevention while ensuring the convenience of using the socket.
[0018]
In the present invention, the member to be coated is a transparent and thermoplastic synthetic resin agent, and a predetermined region is coated and solidified in a gel state.
[0019]
When a plastic synthetic resin such as an epoxy resin is in a gel state, the epoxy resin is poured into a predetermined region. Then, the external electricity supply can be interrupted by solidifying. Moreover, since the trace remains when it is forcibly removed, for example, it is possible to quickly identify fraud such as falsification of internal data from a covered terminal. The synthetic resin is preferably transparent.
[0020]
In the present invention, the integrated circuit is a programmable logic device (PLD).
[0021]
A PLD is used as an integrated circuit. The PLD can rewrite program data and parameter data once written, unlike the ONE TIME ROM, which has been widely used in the past. That is, since data can be rewritten and reused without being disposable, versatility is enhanced, leading to reduction of so-called industrial waste.
[0022]
However, the use of PLD makes it possible to easily rewrite as described above, so that the rewriting may be performed illegally. Therefore, as described in claims 1 to 6, when a predetermined region is covered and this coating is peeled off, a trace remains so that fraud cannot be made.
[0024]
Further, in the present invention, a liquid crystal display device that produces an effect for determining whether or not the electronic component is in a state advantageous to at least a player, a decorative lamp for arousing a player's hobby, and an effect sound source It is characterized by including.
[0026]
That is, in a gaming machine, the use of PLD provides general versatility, and when the game content is changed, it is only necessary to rewrite internal data, and the work such as replacement can be omitted. Further, a part of the terminals of the PLD or almost the whole other than the other terminals are coated so that they cannot be directly contacted from the outside (particularly, they are electrically non-conductive). Furthermore, when this coating member is peeled off, traces remain, so that even if the PLD is tampered with illegally, it can be quickly found by visual inspection.
[0027]
In addition to the components in the circuit board, the electronic components of the pachinko machine are liquid crystal display devices that are used to determine whether or not the player is in an advantageous state. Includes decorative lamps and sound sources.
[0028]
DETAILED DESCRIPTION OF THE INVENTION

[0029]
A plurality of nails 16 are driven into the gauge portion 14 over the entire surface (only the main portion is shown in FIG. 1), and pachinko balls launched through the rails 12 hit the 16 and are formed by the nails 16. It is going to fall while being guided by the guideway. In addition to this nail 16, a windmill 18 is attached at a symmetrical position toward the gauge portion 14 so as to change the direction of the pachinko ball in an unexpected direction.
[0030]
Further, the gauge portion 14 is provided with a winning opening 20 at a plurality of positions, and when a pachinko ball enters the winning opening 20, a predetermined number of pachinko balls are paid out to the player.
[0031]
Such a gauge part 14 is made into a substantially left-right symmetric system, and the electric accessory unit 22 is arranged in the center part, and the display part 24 is exposed. A start winning opening 26 for starting the electric accessory unit 22 is provided below the display unit 24.
[0032]
A large winning opening 28 is arranged further below the starting winning opening 26 and is opened for a predetermined time in a so-called winning display state on the electric accessory unit 22 so that a large number of pachinko balls can be won. ing.
[0033]
FIG. 2 shows a schematic diagram of the back surface of the pachinko gaming machine 10.
[0034]
A circuit board case 32 in which the circuit board 30 is housed is attached to the center left side of the back surface of the pachinko gaming machine 10. In addition, the direction which becomes an upper part in the attachment state to the pachinko gaming machine 10 in the circuit board case 32 is indicated by an arrow A, and the direction is clarified by this arrow A in other drawings.
[0035]
The circuit board case 32 is attached so that the connector portion 44 is located on the right side (near the center). The connector portion 44 is exposed 4 to the outside of the circuit board case 32.
[0036]
As shown in FIG. 3, the circuit board 30 has a plurality of electronic components including IC chips mounted on a rectangular substrate, and the electric circuit disposed on the game board surface of the pachinko gaming machine 10 by these electronic components. The accessory unit 22 and the like are controlled. The circuit board 30 is covered with a circuit board case 32 at the time of manufacture in order to protect the circuit board 30 from contact with other conductive parts, impact, and the like.
[0037]
Here, in this embodiment, as shown in FIGS. 4A and 4B, a PLD (programmable logic) is used as a memory element for programming a game form of the pachinko gaming machine 10 in the IC chip.・ Device) 100 is applied.
[0038]
In addition to control program data, various parameter data are stored in the PLD 100, and a sub control board (for example, the electric accessory unit 22 of the electric accessory unit 22) mounted on the pachinko gaming machine 10 from a CPU that operates based on the control program data. A command signal is output to a design control board, sound effect control board, lamp control board, launch control board, payout control board, and the like.
[0039]
The PLD 100 has a thin rectangular shape, and a plurality of terminals 102 are exposed from the four sides, and each terminal 102 is electrically connected to other electronic components by joining (soldering 104) on the circuit board. Combined with
[0040]
Here, the PLD 104 is covered with a transparent epoxy synthetic resin 106 including a rectangular case as well as this terminal without a gap. That is, when the synthetic resin 106 is poured in a gel state (see FIG. 4C), the entire PLD 100 is covered with a thin film and solidified as it is. At this time, only the terminal 102C for inspecting (checking) the state of internal data among the plurality of terminals 102 is not covered with the synthetic resin 106 but exposed. Therefore, in order to recognize the internal state of the PLD 100 later, the data content can be read by bringing a predetermined inspection terminal into contact with the exposed terminal.
[0041]
On the other hand, the input / output terminal 102i / o capable of rewriting data stored in the PLD 100 is covered with the synthetic resin 106 together with the entire case, and cannot be contacted with the outside. Connection is also impossible. That is, although the PLD 100 can rewrite data, it is prevented from being easily rewritten by being covered with the synthetic resin 106.
[0042]
Further, when the synthetic resin 106 is forcibly peeled off, the trace remains on the PLD 100, and has the same function as a so-called sealing seal.
[0043]
The operation of the present embodiment will be described below.
[0044]
The electric accessory unit 22 provided on the game board surface of the pachinko gaming machine 10, the decorative lamp, the sound effect speaker, the firing knob, the pachinko ball payout, and the like are controlled by various control boards provided on the back surface of the game board surface. The Among these, the circuit board 30 is a main control board, and a pattern control board for the electric accessory unit 22, a lamp control board for a decorative lamp, a sound effect control board for a sound effect speaker, and a launch control board for a launch knob. A command signal is output to each of the payout control boards for paying out pachinko balls to control the entire game.
[0045]
The PLD 100 mounted on the circuit board 30 stores control program data and various parameter data, and the CPU controls based on the stored data. Hereinafter, an example of control will be described.
[0046]
A plurality of special symbol combinations are stored in advance in the PLD 100, and the CPU compares the actually displayed symbol pattern combination with the stored symbol combination and the comparison result (match or mismatch). (Actually, the hit / loss is determined when the pachinko ball enters the start winning opening 26).
[0047]
If it is determined as a result of comparison, a so-called winning state is obtained, the special winning opening 28 is opened for a predetermined time, and a large amount of pachinko balls are paid out to the player.
[0048]
Here, since the game content in the pachinko gaming machine 10 including the probability of winning is controlled based on the data stored in the PLD 100, the game content is changed by replacing the PLD 100 or rewriting the data. Is possible.
[0049]
That is, by using the PLD 100, it is possible to obtain new game contents by rewriting to new data without exchanging, and versatility is enhanced. As a result, industrial waste is reduced.
[0050]
On the other hand, being able to rewrite easily means that it is also easy to rewrite illegally. For this reason, in this embodiment, illegal rewriting (exchange) is prevented by covering the PLD 100 with the synthetic resin 106.
[0051]
That is, the gel-like synthetic resin 106 (see FIG. 4C) is poured into almost the entire area of the PLD 100 (including the terminals 102i / o) and then solidified, so that the PLD 100 is covered with the thin synthetic resin 106. Of course, the synthetic resin 106 is indispensable for insulation, but is preferably subjected to UV cut treatment. As a result, the PLD 100 cannot swing directly including the terminal 102 i / o, and the synthetic resin 106 is non-conductive, so that it cannot be electrically connected to the terminal 102 and data cannot be rewritten. .
[0052]
Furthermore, since the circuit board 30 is also equipped with a ROM, even if the data inside the ROM is analyzed, the operation including the circuit board 30 cannot be recognized unless the inside of the PLD is analyzed, thus preventing fraud. It becomes.
[0053]
Note that the terminal 102C for confirming the internal data is kept exposed when it is coated with the synthetic resin 106, so that when the inspection is necessary, the internal data of the PLD 100 is removed without peeling off the synthetic resin. The state of can be confirmed.
[0054]
Further, the input / output terminals 102i / o for rewriting data are covered with a synthetic resin, and when the synthetic resin is forcibly removed and the data is tampered with illegally, a trace of the synthetic resin 106 being peeled remains. It is possible to quickly recognize that fraud has been performed visually.
[0055]
As described above, in this embodiment, the rewritable PLD 100 is used in place of the logic IC that cannot be changed conventionally, and the PLD 100 is covered with the synthetic resin 106 by taking advantage of the high versatility. By doing so, since the demerit of unauthorized rewriting is prevented, it is possible to achieve both of the trade-offs between data rewrite ease and fraud prevention.
[0056]
In this embodiment, only the inspection terminal 102C of the PLD 100 is excluded and the other entire area is covered with the synthetic resin 106, but only the data input / output terminal 102i / o is covered with the synthetic resin 106. You may make it do (refer FIG. 5).
[0057]
Thus, rationalization is achieved in terms of cost and manufacturing process by making the portion to be covered not only the entire surface of the circuit board 30 but only a necessary portion. It is also effective for inspections at inspection institutions.
[0058]
In this embodiment, the PLD 100 is directly joined (soldered) to the circuit board 30. However, as shown in FIGS. 6A and 6B, a socket 108 may be interposed. In this case, the input / output sub-terminal 110 of the terminal (sub-terminal) 110 provided in the socket 108 needs to be covered with at least the synthetic resin 106. Further, it is desirable to dispose the synthetic resin 106 so that the boundary between the socket 108 and the PLD 100 is continuous. This is because traces remain when the PLD 100 is replaced. Furthermore, an ID number may be assigned between the socket 108 and the PLD 110 for management.
[0059]
In the present embodiment, a pachinko machine has been described. However, the present invention is not limited to this, and can be applied to, for example, a pachislot machine.
[0060]
