DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention restricts the remodeling of a connection board used for outputting signals from a game machine such as a pachinko machine to a hall computer of a pachinko parlor, or the board or cables related to the board. Regarding the substrate to be. More specifically, the present invention relates to a board and an inspection machine having a function of retaining traces of modification performed on the board, an inspection method of the board, and a gaming machine equipped with the board.

[0002] In the present application, the term "modification" refers to the addition or removal of parts to a board or cables related to the board, the addition of conductors, the removal of conductors, and the replacement of cables related to the board or the board. Include in. Also, “modifications” include those that abandoned halfway without completing the modification. Furthermore,
In the present application, a person who intends to carry out "modification" and a person who has already carried out "modification" are referred to as "modifications". Whether the term "modified person" in the text means a person who has not performed the modification or a person who has already performed the modification has been understood in accordance with the context and the meaning and in accordance with the common sense of those skilled in the art. Further, in the present application, a description will be given by taking a pachinko machine and a connection board thereof as an example, but this is for the purpose of embodying the description and for promoting the reader's understanding, and is not intended to limit the technical scope of the present invention. The present invention is not limited to pachinko machines and other gaming machines,
The remodeling and replacement can be applied to various substrates to be regulated and prevented. In the present application, not only components (active elements, passive elements, connectors, etc.) and conductors related to the original function of the substrate, but also members attached to the substrate for implementing the present invention can be subject to “modification”. Caught. That is, the “remodeling” that can keep a trace of the remodeling in the present invention also includes a “remodeling” measure for members for implementing the present invention.

[0003]

[Prior Art] One of the necessary points in the management and operation of pachinko parlors is to avoid inciting the gambling of players,
In some cases, the player may not be unreasonably disadvantaged. As one of the measures to this end, the pachinko industry and the government offices and agencies that have jurisdiction over this will install devices on each pachinko machine that control circuits and mechanisms (so-called “panels”) that control the way the balls come out. A measure is taken to make it difficult for the player to easily operate the ball from outside. Normally, this control device is mounted on the back of a pachinko machine as a control board on which a CPU is mounted. In addition, in the management and operation of pachinko parlors, it is necessary to prevent illegal players and players from illegally operating the balls and boards. For this purpose, mechanisms (so-called "frames") that can be operated by a player, such as a launch handle, a ball rental machine, a door, etc.
It is necessary to monitor the status of Furthermore, in order to efficiently manage a pachinko parlor, it is necessary to centrally manage information about the operation status of the board, for example, the frequency of jackpots and the status of symbol confirmation.

[0004] From these needs, a device for outputting a signal indicating the state of the frame or the board is provided on each pachinko machine, and a signal from this device is received by a management computer called a hall computer or the like. To grasp the operation status of many pachinko machines installed in the store in real time,
In general, a system configuration is adopted. A signal output device from the pachinko machine to the hall computer is called a terminal board or a connection board, and is generally mounted on the back of the pachinko machine. As shown in FIG. 1, the connection board 2 relays a group of signals 4 output from a gaming machine such as a pachinko machine (strictly, a control board incorporated therein) 1 to a hall computer 3. The connection board 2 is, for example, an insulating board, a connector to which a cable for transmitting the signal group 4 is connected, a connector to which a connector for supplying the signal group 5 to the hall computer 3 is connected, and a signal direction is predetermined. And a conductor pattern formed on a board for connecting these connectors and the circuits, and is incorporated into the back of the gaming machine 1. Here, the gaming machine 1 is shown for simplicity of illustration.
However, a number of gaming machines 1 are installed in an actual pachinko parlor. A predetermined number of connection boards 2 are provided for each gaming machine 1, and each gaming machine 1 is connected to the hall computer 3 via a connection board 2 dedicated to the game machine 1.

[0005] The connection board 2 does not have the function of modifying the signals, and therefore the signal group 5 supplied to the hall computer 3 has the same content as the signal group 4. The signal flow in the connection board 2 is a flow in the direction of supplying information indicating the operating state of the gaming machine including the operating state of the control board from the control board of the gaming machine 1 to the hall computer 3;
There is no flow in the opposite direction, that is, a flow for supplying a signal from the hall computer 3 to the control board of the gaming machine 1. This means that if a signal is supplied from the hall computer 3 to the control board of the gaming machine 1, the operation of the control board of the gaming machine 1 by using the transmission line of the signal, and furthermore, how the ball is ejected, This is because a fraudulent act of artificially operating the "big hit", the operation of the "special electric accessory", the determination of the "symbol", and the like is performed. However, as for the frame terminal board of the pachinko machine, conventionally, a signal for stopping the firing of the ball is provided from the hall computer 3 to the control board of the gaming machine 1. There is no such exception for pachinko board terminal boards, and the signal flow is always the gaming machine 1
Flow from the control board to the hall computer 3.

[0006]

In spite of various measures for preventing fraud such as restricting the direction of signals on the connection board, illegal remodeling is actually performed. It is possible. For example, as an example of an illegal remodeling action, a signal indicating the number of payout prize balls different from the number of balls actually paid out from a gaming machine to a player during a jackpot is supplied to a hall computer. There is something. Modifications to achieve this include replacing / rewriting the ROM on the control board or modifying the cable connecting the control board to the connection board or the cable connecting the connection board to the hall computer. Is possible.

[0007] The fraud by these techniques cannot be prevented or detected only by regulating the signal direction in the connection board. In order to detect this kind of fraud, it is necessary to collate the result of visually observing the appearance of the ball in the hall of the pachinko parlor with the data stored in the hall computer. Since a large number of gaming machines (pachinko machines, etc.) are installed in pachinko parlors, a great deal of effort is required to visually observe the appearance of the balls, etc. for all of them, and balls by visual observation in the hall It requires a high level of skill and attention to understand the appearance of the data, and the work of collating the results with data is more troublesome. Further, if data is processed in the hall computer (whether or not it is intended to conceal fraud), there is a high possibility that fraud cannot be found even by this collation. The same applies to fraudulent operations such as an operation of a jackpot probability and an operation of a continuous appearance rate of probability-variable patterns, without being limited to the operation of the payout prize ball number information during the jackpot.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is intended to intervene in signal transmission such as a connection board provided between a control board of a game machine and a hall computer. An object of the present invention is to provide a member for evaluating the content of a signal on a substrate so that a modification belonging to a modification of the content of a signal can be found easily, at low cost, and quickly and reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the following description, the system shown in FIG. 1 is assumed for the sake of simplicity of description, and description of the same parts as in the related art will be omitted.

FIG. 2 shows a configuration of the connection board 13 according to the first embodiment of the present invention. Connection board 13 according to the present embodiment
Has a signal transmission line for connecting (not shown) a connector on the control board side and a connector on the hall computer side (via various components or directly). Although there are usually many signal transmission lines of this kind, FIG. 2 shows a line 6 for transmitting a prize signal indicating a prize and a prize ball number signal indicating a prize ball number among these many lines. 1 is shown. One of the features of the present embodiment is that, by attaching a counter, an arithmetic unit, a display, and the like to these lines 6 and 10, a function of displaying the trace (signal) so that the fact of the modification can be easily found. Monitor function). In the figure, a counter 6, a calculator 8 and a display 9 are provided on a line 6, and a counter 11 is provided on a line 10.
And a display 12 are respectively provided.

First, the winning signal 1 transmitted by the line 6
Is counted by the counter 7. The number of occurrences of this signal based on the predetermined time point, that is, the count value of the signal number, indicates the number of winnings from the predetermined time point. The arithmetic unit 8 determines whether the information held by the counter 7, that is, the number of winnings,
The number of payout prize balls from the above-mentioned predetermined time is obtained by an operation such as multiplying by the number of prize balls per round. This is information that can be compared with the counting result in the counter 11 described later. The display 9 displays the counted and calculated number of winnings, the number of payout balls, and the like in the form of numerical values, graphs, and the like. The prize ball number signal 2 transmitted by the line 10 is counted by the counter 11 on the basis of the predetermined time point. This count value indicates the number of payout prize balls from the above-mentioned predetermined time, and is displayed on the display 12 in the form of a numerical value, a graph, or the like.

Accordingly, the inspector can obtain information on the number of winnings and the number of payout prize balls calculated based on the display on the display 9, and obtain the payout prize ball on the display on the display 12. Information about numbers can be obtained. A statistical discrepancy between the number of payout prize balls displayed on the display 9 and the number of payout prize balls displayed on the display 12, that is, a difference such that the probability of occurrence in a state in which unauthorized modification is not performed is low. By simply observing whether or not there is, the inspector can easily find a signal modification such as an illegal operation of the winning signal or the prize ball number signal upstream of the connection between the counters 7 and 11. Further, by comparing the displayed information with the information stored in the hall computer 3, an unauthorized data operation in the hall computer 3 or a counter 7
Alternatively, it may be possible to find fraud such as alteration of a signal in a portion from the connection portion 11 to the hall computer 3.

As described above, in this embodiment, when relaying a signal from the control board to the hall computer 3,
An easy-to-understand index for judging the statistical normality / abnormality of a signal is derived and provided by simple means.
Therefore, for example, a method of replacing / rewriting the ROM mounted on the control board, designing a cable for connection with the control board or the hall computer 3, and designing data on the hall computer 3 is adopted. While the number of payout prize balls during the jackpot is reduced, the hall computer 3 and the like are fraudulent, such as reporting a prize ball number different from the actual payout prize ball number from the gaming machine 1. We can deal with cases. That is, even if there is this kind of fraud, the visual comparison of the information displayed by the indicators 9 and 12 makes
Alternatively, by comparing the data with the data on the side of the hall computer 3, the trace can be found accurately, reliably, at low cost and with reduced labor. Further, the display content (and data content) check operation for that can be performed in a short time before opening the store, after closing the store, and the like.

In the above description, the number of winnings and the number of winning balls are detected and compared with each other, but the method according to the present embodiment can be similarly applied to the number of jackpots and the number of picture rotations. That is, the method according to the present embodiment is applied to a line that transmits a signal indicating a jackpot or a signal indicating a picture rotation, and obtains and displays the jackpot probability and the number of picture rotations by counting (and calculating based on) the signals. Therefore, fraud such as intentionally increasing the jackpot probability and decreasing the continuous appearance rate of the probability-variable pattern can be detected more reliably and at lower cost than before. Further, according to the present embodiment, it is possible to detect and point out a fraud in a signal based on a statistical index that is widely recognized as objectivity, so that the reliability in detection of modification is higher than in the past. The display 9
Alternatively, a memory, an external recording medium, or a communication line connection unit may be provided instead of or together with 12. The inspector may be a human or a robot.

FIG. 3 shows a configuration of a connection board 22 according to a second embodiment of the present invention. A characteristic feature common to the first embodiment is that a counter is attached to a necessary one of a plurality of signal transmission lines provided on the connection substrate 22 and the number of signals is counted by the counter. . In the present embodiment, the output signals 16 from the circuit 14 on the connection board 22 to the hall computer 3 are further counted by counters 17, 18, and 18.
19, and the circuit 1 on the board from the control board side
The evaluator 20 evaluates the counting result by appropriately using the input signal group 15 to 4, and displays the result on the display 21.

The evaluator 20 in the present embodiment is the same as the arithmetic unit 8 in the first embodiment that derives the number of payout balls from the number of winnings and derives information that can be compared with the counting result by the counter 11. And a function for deriving information necessary for comparison or display from the counting result and displaying the information on the display 21. In the first embodiment, information obtained as a result of counting (and calculation) is displayed as a numerical value or a graph. In the present embodiment, the number of winnings, the number of payout balls, the number of jackpots,
Such display is possible for the pattern rotation speed, the probability variation probability, and the like.

Further, the evaluator 20 in the present embodiment comprises:
It also has a function of generating and displaying error information based on the result of comprehensively determining the presence or absence of fraud. That is, the evaluator 20 generates error information indicating which signal has been modified based on the counting result, and causes the display 21 to display the information in the form of characters, LED lighting, or the like. Therefore, compared to the first embodiment, the probability of the inspection person overlooking the fact of the signal alteration is reduced.

In order to specify a signal that has been modified to generate error information, for example, a counting result (number of winnings, etc.) obtained by the counter 17 and a counting result (payout award) obtained by the counter 18 are used. And the number of spheres). If there is a statistical inconsistency between the two, for example, if there is a large difference between the two that the probability of occurrence is less than a predetermined reference value when no tampering is performed, the counter 17
It can be considered that any of the signal counted by the counter and the signal counted by the counter 18 has been modified.
The location where the wiring or component is changed / added / deleted for signal modification is located on the upstream side of the signal content detection point by the counters 17 and 18, that is, on the control board side, or in the signal transmission line. Or in a test line or circuit including the unit 17 or 18. The evaluator 20 then determines the signal counted by the counter 17 and the counter 18
Are displayed on the display 21 in accordance with a predetermined code or the like, indicating that any of the signals counted by the above has been modified, or where there is a possibility that such modification has been made.

Also, there is a statistical discrepancy between the counting result obtained by the counter 17 and the counting result obtained by the counter 18, and the counting result obtained by the counter 17 and the counting result obtained by the counter 19 are different. There is a statistical inconsistency between the counted result and the counted result obtained by the counter 18 and the counter 19.
There is no statistical inconsistency with the counting results obtained by
In such cases, it is appropriate in many cases to consider that the signal counted by the counter 17 has been modified, and furthermore, the signal transmission line on the upstream side of the signal content detection point by the counter 17. Alternatively, it is appropriate to consider that the modification operation has been performed on the inspection line / circuit including the counter 17. The evaluator 20 uses the indicator 21 to determine whether the signal counted by the counter 17 has been modified or where such modification has been performed. And so on.

Further, in this embodiment, since the input signal to the on-board circuit 14 is also supplied to the evaluator 20,
The inconsistency that appears between the input and output to the on-board circuit 14 due to the modification made on the connection board 22 can also be detected by the evaluator 20. The evaluator 20 detects this kind of inconsistency by comparing the input signal to the on-board circuit 14 with the counting result,
An error signal is generated according to the result. By combining this with the detection of statistical inconsistency by comparing the counting results, it is possible to more accurately or precisely identify the signal targeted for modification and the location where the modification operation was performed, and inspect the result. Can be notified. Note that the present invention can also be implemented in a form in which a discrepancy between an input signal and a counting result is detected and the result is reported, but comparison is not performed between signals on different signal transmission lines.

Further, the evaluator 20 in this embodiment can be shared by a plurality of substrates. For example, in each of a plurality of connection boards mounted on one gaming machine 1, a counter is provided for each required signal transmission line, while an evaluator is provided with a plurality of connection boards mounted on the gaming machine 1. It is provided only on one of the substrates. Further, a signal line for connecting the connection boards is provided, whereby the counter on the connection board on which the evaluator is not provided is connected to the evaluator. Alternatively, in the same type of connection board mounted on each of the plurality of gaming machines 1, a counter is provided for each required signal transmission line, while an evaluator is mounted on any one of the gaming machines 1. It is provided only on the connection board. Further, a signal line for connecting the gaming machines (between the connection boards) is provided, whereby the counter on the connection board on which the evaluator is not provided is connected to the evaluator. When comparing the connection boards or gaming machines, in the short term, there may be a difference in the way the ball comes out, etc., but if you take a sufficiently long time, if it has not been remodeled, The differences should be almost inconspicuous. Therefore, by comparing the signal counting results between these connection boards or game machines, signal modification to the connection board having an evaluator or the game machine 1 on which the connection board is mounted,
Signal modification in other connection boards or other gaming machines 1
Any of them can be detected and notified to the person in charge of inspection.

FIG. 4 shows a configuration of an inspection machine 28 according to a third embodiment of the present invention and a method of using the same. In the drawing, a connector 26 to which a cable for connection to the control board is connected and a connector 27 to which a cable for connection to the hall computer 3 are connected are mounted on the connection board 24. At the time of inspection, these cables are disconnected and the inspection machine 28 is connected. That is, the output side connector 31 of the inspection machine 28 is connected to the connector 26, and the input side connector 32
To the connector 27 using a cable or the like.

In the inspection machine 28, a pulse generator 29 and an evaluator 30 are provided. The pulse generated by the pulse generator 29 is converted into a signal group 23 by the connectors 31 and 26.
Is supplied to the wiring on the connection board 24 via the. The signal appearing at the connector 27 via this wiring is supplied to the evaluator 30 via the connectors 27 and 32. Pulse generator 29
Is a circuit for generating an inspection (pulse) signal simulating a signal from the control board. Connection board 24
If the device is operating normally without any unauthorized modification, the (pulse) waveform of the signal applied via the connector 26 should appear at the connector 27. Then, the evaluator 30 compares the signal for inspection generated by the pulse generator 29, that is, the output from the connector 31, with the response from the connection board 24 to this signal, that is, the input to the connector 32, and compares the signal. The presence / absence, waveform match / mismatch, etc. are evaluated and determined. The result is stored and stored in the inspection machine 28 or output to various display devices and recording media. As a result, the fact of modification of the substrate 24 can be easily found.

The connection board 24 shown in FIG. 4 may be provided with a counting / calculating / displaying function as shown in FIG. 2, or the evaluator 30 shown in FIG. It is also possible to provide a function corresponding to 20 and the display 21. In such a case, when the inspection is performed using the inspection machine 28, the display status on the display on the connection board 24 and the display on the evaluator 30 are compared to more accurately grasp the modification status. be able to.
For example, when the display on the connection board 24 side indicates “normal” and the display by the evaluator 30 indicates “abnormal”, the remodeled part is located after the counter on the connection board 24 and the connector 27.
There is a high probability of being earlier. Further, “abnormality” is detected by comparing the display on the connection board 24 side in a state where it is connected to the control board and the hall computer 3 with the information stored in the hall computer 3. If the display on the connection board 24 side and the display by the evaluator 30 indicate “normal” in a state where the connection board 24 and the hall computer 3 are connected, the probability that the cable connecting the connection board 24 and the hall computer 3 has been modified has been changed. Is high. In this way, by combining the configuration shown in FIG. 2 or FIG. 3 with the configuration shown in FIG.
