[0002]

2. Description of the Related Art Generally, in a pachinko machine, the entire pachinko machine is controlled by a main control board. Therefore, tampering, such as making it easier to hit than usual, may be performed by modifying this main control board.
For example, by changing an integrated circuit component such as a CPU or a ROM provided on the main control board with another unauthorized component, illegally controlling the payout may be performed.

When an illegal operation is performed on an integrated circuit provided on a main control board, an illegal integrated circuit component in which another component such as a resistor is added between terminals of the integrated circuit is often used. In this case, fraud is performed by stealing the clerk's eyes, removing the regular part, and attaching a modified integrated circuit part prepared in advance instead.

[0004]

When the above-mentioned illegal parts are attached, it is important to detect the parts early and to minimize the damage. However, illicit components modified on the back side of the integrated circuit component, that is, the surface facing the wiring board, are often used, so it is difficult to find the illicit component only by visual inspection, and an effective solution is desired. I was

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a pachinko machine fraud prevention structure which can easily detect fraud applied to integrated circuit components. It is to be.

[0006]

A pachinko machine fraud prevention structure according to the present invention is a fraud prevention structure for preventing fraudulence of a specific component mounted on a wiring board of a pachinko machine. An empty space is provided between the component and an adjacent component adjacent to the component. In this case, the adjacent component is, for example, a component mounted with a clock generation circuit that generates a clock supplied to the specific component.

Another structure for preventing fraudulent use of a pachinko machine according to the present invention is a specific component wherein a socket mounted on a wiring board and a terminal are electrically connected to the socket by inserting the terminal into the socket. Wherein the socket has a height such that a lower surface of the specific component is positioned higher than an upper surface of another component adjacent to the specific component, The rear surface of the specific component can be observed while being inserted into the socket.

In addition, the fraud prevention structure for a pachinko machine according to the present invention is a specific component wherein a socket mounted on a wiring board and a terminal is electrically connected to the terminal by inserting the terminal into the socket. And a part of the socket is formed of a transparent member so that a back surface of the specific component can be observed in a state of being inserted into the socket. Further, a fraud prevention structure in a pachinko machine including a socket mounted on a wiring board and a specific component in which the terminal is electrically connected to the socket by inserting the terminal into the socket, The socket has a height such that a lower surface of the specific component is positioned higher than an upper surface of another component adjacent to the specific component, and a part of the socket is formed of a transparent member, The rear surface of the specific component may be observed while being inserted into the socket. In addition, the said socket shall comprise the part other than the part required for electrical connection with a transparent member.

Still another structure for preventing fraudulent use of a pachinko machine according to the present invention includes a socket mounted on a wiring board,
A fraud prevention structure in a pachinko machine including a specific component that electrically connects the terminal and the socket when the terminal is inserted into the socket, wherein the socket is a first side surface of the specific component. The distance between the insertion part corresponding to the terminal group arranged on the second side surface of the specific component and the substrate surface is larger than the distance between the insertion part corresponding to the terminal group arranged in the first direction and the substrate surface. Or, the distance between one of the first and second side surfaces on which the terminals of the specific component are not arranged and the substrate surface is larger than the distance between the other and the substrate surface. I do.

Another aspect of the pachinko machine according to the present invention is a pachinko machine in which a first side of the game board is supported by an outer frame and a second side substantially parallel to the first side about this axis. In a pachinko machine configured so that the back side of the game board can be observed by separating the game board from the outer frame, a fraud prevention structure for preventing fraudulence of specific parts provided on the back side of the game board, The component is provided on the back side of the game board such that the side surface on which the terminal is not provided faces the second side surface, so that the back surface of the specific component can be observed.

In short, by providing an empty space, increasing the height of the socket, using a transparent material, or mounting a specific component at an angle, it is easier to observe the back side of the specific component, making it easier to find fraud and prevent fraud. It is doing.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the same parts as those in the other drawings are denoted by the same reference numerals. FIG. 1 shows the layout of each component on the main control board of the pachinko machine. As shown in FIG. 1, the main control board 1 includes a CPU 10 as a component for controlling the entire pachinko machine, and a CPU 1
The circuit includes an oscillation circuit 11 for supplying a clock to 0, a collective resistor 12, and a power supply circuit P for supplying power to each component mounted on the board. As shown in the figure, no components are provided around the CPU 10 provided on the surface of the main control board 1. That is, the hatched portions shown in the figure are empty spaces and no components are provided. Thus, the back surface of the CPU 10 can be observed from a gap between other components, and an unauthorized component can be easily found. In addition, since an empty space such as a hatched portion is provided, the tip of the component removing tool can be easily inserted, and the IC
It becomes easy to remove the CPU 10 mounted on the board 1 via the socket. By removing the CPU 10, the back side can be observed, so that fraud can be easily confirmed.

FIG. 2 shows a layout of each component on a general main control board. In the main control board 1 shown in FIG.
Other components such as a collective resistor 12 are provided. That is, other components are provided around the CPU 10 indicated by oblique lines in the figure, and the CPU 10 is provided close to an adjacent component. Therefore, CPU
Even if a component is added to the back side of the device 10 and a fraudulent process is performed, another component adjacent to the component 10 becomes a hindrance and the added component cannot be found.

On the other hand, if an empty space is provided as shown in FIG. 1 described above, other parts adjacent to the CPU 10 do not become an obstacle, and the back side of the CPU 10 can be easily observed. As a result, a component added on the back side of the CPU 10 can be found. Incidentally, it is better to make the empty space shown in FIG. 1 as large as possible. However, if the free space is made unnecessarily large, a clock is generated, and the oscillation circuit 11 that supplies this clock to the CPU 10 is provided at a position distant from the CPU 10, which causes a problem that noise appears in the clock waveform. . In order for the CPU 10 to operate normally, a clock having a correct waveform needs to be supplied, and it is not preferable to provide the oscillation circuit 11 at a position away from the CPU 10.

According to the inventor's experience, the empty space is the CPU
It is desirable to provide around 1 cm about 10 cm. And if you have this much free space,
When the CPU 10 is mounted on the board 1 via an IC socket, the tip of a component removal tool can be easily inserted, and the use of this tool facilitates component removal. By removing the CPU 10, the back side can be observed, so that fraud can be easily confirmed. In short, it is sufficient to provide an empty space in which the tip of the component removal tool can be inserted.

FIG. 3 shows a regular part and an unauthorized part. FIG. 1A shows regular components, and a CPU 100 is mounted on a socket 100. CPU1
By electrically connecting the 0 terminals to the contacts of the insertion portion of the socket 100, the CPU 10 is electrically connected to other components on the main control board via the socket 100.

FIG. 2B shows an unauthorized part.
As shown in the figure, the state where the resistors R1 and R2 are added to the back side of the CPU 10a can be observed from the gaps between the terminals. CPU with parts added on the back side like this
By providing 10a instead of a regular CPU,
It is possible to make the pachinko machine operate improperly. Since the appearance of the front surface of the CPU 10a is almost the same as that of a legitimate CPU, it is often difficult to determine whether or not the CPU is illegal without observing the back surface of the component. Therefore, as described above, by providing an empty space around the CPU, the back surface of the component can be observed from the gap between the terminals.

By the way, as shown in FIG. 1C, even when the number of parts is large, the size of the main control board is small, and the like, no empty space can be provided.
If the height H of the socket 100 is set higher than the height of the surrounding components, the back side of the CPU 10 can be easily observed from the gap between the terminals. Thereby, it is possible to easily find a component such as a resistor that has been added illegally. That is, CP
The height H may be determined so that the lower surface of U10 is positioned higher than the upper surface of another adjacent component.

If at least a part of the socket 100, for example, a part other than a part necessary for electrical connection, is molded with a transparent resin or the like, the observation of the back side of the CPU 10 becomes easier. As shown in FIG. 4A, since a predetermined height H1 is provided from the socket 100 to the back side surface of the CPU 10, parts such as the above-described resistor may be added to this portion. is there. However, socket 1
If a transparent material is used for 00, the back side can be easily observed. Further, as shown in FIG. 3B, if the height H2 from the socket 10 to the back side surface of the CPU 10 is set to be larger than the height H1 in FIG. Can be observed. However, if the height H2 is too large, the case for accommodating the main control board must be large. So, C
It is desirable to select the height H2 such that the upper surface of the PU 10 is equal to or less than the height of the component having the largest height on the main control board. For example, if the height of the power supply circuit P is the highest in the main control board, it is necessary to select the height H2 so that the upper surface of the CPU 10 is equal to or less than the height of the power supply circuit P.

By the way, in order to facilitate observation of the back side of the CPU 10, as shown in FIG.
10 may be mounted so that its upper surface is inclined with respect to the main control board surface. Socket 101 used in this case
The height of one of the two side surfaces on which the terminal group of the CPU 10 is provided is H1, and the height of the other is H2 higher than H1. That is, the distance between the insertion portion corresponding to the terminal group arranged on the first side surface of the CPU 10 and the surface of the board is larger than the distance between the insertion portion corresponding to the terminal group arranged on the second side surface of the CPU 10 and the surface of the board. It is configured so as to increase the distance between the object. In this case, it is assumed that the socket is made of a transparent material except for a portion necessary for electrical connection. Using such a socket 101, the CPU 10
By mounting the CPU 10 so that its upper surface is inclined with respect to the main control board surface, the back side of the CPU 10 can be observed through the transparent material of the socket 101 from the direction of arrow Y1, that is, the direction of the side surface on which the terminals are provided. You can do it.

As a method of mounting the CPU 10 so that the upper surface thereof is oblique, the form shown in FIG. In the embodiment shown in FIG.
02 is H2 where one of the two side surfaces on which the terminals are not provided is H1 and the other is higher than H1. That is, the socket is configured such that the distance between the other side and the substrate surface is larger than the distance between the one side where the terminals of the CPU 10 are not arranged and the substrate surface. Also in this case, the CPU 10 is mounted so that its upper surface is inclined with respect to the main control board surface.
The back side of the CPU 10 can be observed from the direction of the arrow Y2, that is, the direction of the side surface on which the terminal is not provided. In the case of the figure, the material of the socket 102 does not need to be transparent because the terminal of the CPU 10 does not hinder the back side observation.

The transparent material described in the above description is not limited to colorless and transparent, but may be colored and transparent as long as the color does not hinder observation. When a conductive transparent material, for example, a material used for a transparent electrode or the like is used, a portion required for electrical connection of the socket can be made transparent. This makes it easier to observe the back side of the CPU.

When the CPU is arranged on the main control board, the CPU
Changing the direction of 10 makes it easier to observe the back side. This embodiment will be described with reference to FIG. As shown in FIG. 5A, the pachinko machine is
One side surface 5a of the game board 5 is pivotally supported by the outer frame 51, and a side surface 5b substantially parallel to the side surface 5a about this axis is provided on the outer frame 51.
The door is opened as shown by an arrow Y3 away from the game board 5, so that the back side of the game board 5 can be observed. On the other hand, by bringing the side surface 5b closer to the outer frame 51 in the direction opposite to the arrow Y3, the door is closed, and a game is possible. In this pachinko machine, a case 2 is provided on the back side of the game board 5, and a main control board 1 is provided inside the case 2.

In the main control board 1 arranged as described above, the CPU 10 may be mounted so that the side of the CPU 10 where the terminals are not provided faces the side 5b of the game board 5. That is, if the direction of the side of the CPU 10 where the terminals are not provided is aligned with the direction of the side 5b of the game board 5 as shown in FIG. Even so, the back side of the CPU 10 can be observed from the direction of the arrow Y4.

In this case, as shown in FIG. 6, the positions of the oscillation circuit 11 and the power supply circuit P are almost the same as those in FIG. 1, and the arrangement of the CPU 10 and the collective resistor 12 may be changed. Then, as shown in FIG. 4 (d), the height of the side surface 5a of the game board 5 is H1 and the height of the side surface 5b is two among the two side surfaces on which the terminals are not provided. H
By setting H2 higher than 1, it becomes easier to observe the back side of the CPU 10.

On the other hand, when the direction of the side surface on which the terminal of the CPU 10 is provided and the direction of the side surface 5b of the game board 5 coincide with each other as shown in FIG. As it is, the CPU from the direction of arrow Y4
It is difficult to observe the backside of the 10. Therefore, when the CPU 10 is mounted in the direction shown in FIG. 4C, the back side of the CPU 10 can be easily observed by adopting the above-described embodiment of FIG. 4B or FIG.

A daughter board on which a CPU is mounted is prepared, and the daughter board is mounted on a main control board by the CPU.
May be mounted so that the back side of the camera is easy to observe. For example, C
What is necessary is just to attach so that the side in which the terminal of PU is not provided may face the side of a game board. Also in this case, C
It is easier to observe the back side of the PU. Further, instead of making the material of the socket transparent, the sealing resin of the CPU itself may be made transparent. In this case, it is easy to observe the back side of the CPU without using a transparent socket. If the heat dissipation efficiency is reduced by making the sealing resin transparent,
A radiator plate or a cooling fan may be provided.

In each of the embodiments described above, the case where the CPU is arranged at the peripheral portion of the main board has been described.
It is clear that fraud can be prevented even when is disposed at the center of the main substrate. If the CPU is arranged at the center of the main substrate, the illegal operation performed while the main substrate is covered with the substrate case, such as a heat radiation hole provided on the side surface of the case (a surface substantially perpendicular to the substrate surface). It is possible to make it difficult to perform improper operations to be performed on the CPU from the gaps. Therefore, if the CPU is arranged at the center of the main board, fraud can be more reliably prevented.

In each of the embodiments described above,
If necessary for observation of the back side of the CPU, light may be applied to the back side using a lighting device such as a pen-type light. The above is C
Although the case of preventing improper use of the PU has been described, it is apparent that the present invention is not limited to this, and that improper use of an integrated circuit component such as a ROM can be similarly prevented. That is, it is apparent that the present invention can be used for various specific parts that can be a target of pachinko machine fraud.

Regarding the description of the claims, the present invention can further adopt the following aspects. (1) The first side of the game board is pivotally supported by the outer frame, and the second side substantially parallel to the first side is separated from the outer frame about this axis to observe the back side of the game board.

There is an effect that the tip can be easily inserted, and the component can be easily removed. In addition, by increasing the height of the socket of the specific component, forming at least a part of the socket with a transparent member, or attaching the specific component obliquely, it becomes easy to observe the back side of the specific component,
There is an effect that fraud applied to the component can be easily found. Furthermore, by mounting the specific component such that the side on which the terminal is not provided faces the side of the game board, it becomes easy to observe the back side of the specific component even with a normal socket, and the component is applied to the component. This has the effect that fraudulent misconduct can be easily found.
