Description

  The present invention communicates with a gaming machine controlled by a gaming control device including a gaming machine computer having a communication function with the outside and capable of proper testing by a testing signal, and the gaming machine computer of the gaming machine. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine inspection system that includes an inspection device that checks the suitability of a computer for gaming machines.

  Game machines such as pachinko machines and slot machines are usually controlled by a single-chip microcomputer (hereinafter referred to as a single-chip CPU for gaming machines) containing a ROM storing a game control program. It is controlled by a control device that houses the substrate in a storage case.

  Since the above-mentioned one-chip CPU for gaming machines is directly related to important characteristics of the gaming machine such as the probability of jackpot, the gaming machine is illegally exchanged with a forged gaming machine one-chip CPU or forged. If a gaming machine control board equipped with a single-chip CPU is illegally replaced for each case, the gaming machine will be different from the appropriate gaming machine that is suitable for testing by the testing institution, and it is unforeseen for game shops and players. Will cause damage.

  Therefore, as a technique for preventing forgery of the gaming machine one-chip CPU or for easily discovering that it has been forged, an individual ID (unique identification information) is set in the gaming machine one-chip CPU. In addition, it is possible to increase the confidentiality of the ID by configuring so that the ID set in the one-chip CPU for the gaming machine cannot be read unless a special device (for example, an inspection device such as an ID reader) is used. There has been proposed a technique that facilitates discovery of a forged one-chip CPU for gaming machines and makes it difficult to counterfeit the one-chip CPU for gaming machines (for example, see Patent Document 1).

JP 2000-262710 A

  However, in the technique described in Patent Document 1, although it is possible to inspect whether or not the gaming machine one-chip CPU to be inspected by the inspection apparatus is appropriate, the gaming machine one-chip CPU to be inspected is There is a problem that it cannot be determined whether or not the game control is properly performed.

  For example, a fraudulent gaming machine one-chip CPU is provided on the gaming machine control board separately from a regular gaming machine one-chip CPU, and the actual gaming control is altered so that the unauthorized gaming machine one-chip CPU performs. When a game control device is attached to a gaming machine, in the CPU inspection by the inspection device, the legitimate ID is naturally read from the legitimate gaming machine one-chip CPU, so that the gaming machine one-chip CPU is appropriate. In other words, it is not possible to detect that the game control device itself has been tampered with.

  It is to be noted that unauthorized tampering can easily be exposed if the number or arrangement of various electrical / electronic components on the gaming machine control board is different in the unauthorized installation of an unauthorized gaming machine one-chip CPU. In order to keep the appearance of the board in the same appearance as the regular product, an illegal technique is adopted in which electric / electronic components other than the one-chip CPU for gaming machines and the one-chip CPU for illegal gaming machines are integrated. An I / O port having a relatively large IC chip structure may be used as a tampering part. In such unauthorized tampering, the wiring from the regular one-chip CPU for gaming machines to the I / O port is cut, and the I / O port function and the unauthorized one-chip CPU for gaming machines are integrally molded with resin. The chip is replaced with a regular I / O port chip. In this way, the illegal one-chip CPU for gaming machines can acquire various sensor information necessary for game control from the I / O port, and can output operation control signals to various gaming devices via the I / O port. Game control by an unauthorized one-chip CPU for gaming machines is easily realized.

  In this way, when unauthorized tampering is performed on the gaming control device to replace the unauthorized one-chip CPU for an unauthorized gaming machine with an unauthorized electrical / electronic component, the conventional one-chip for gaming machine is used as in the past. There is a problem that it is not possible to determine that the game control device is appropriate only by the result of the CPU inspection performed by the CPU and the inspection device.

  Therefore, the present invention can not only read and inspect the unique identification information given to each one-chip CPU for gaming machines, but also illegally replace electric / electronic parts other than the one-chip CPU for gaming machines with falsified parts. It is an object of the present invention to provide a gaming machine inspection system capable of inspecting whether or not a game control device is used.

  In order to solve the above-mentioned problems, the invention inspection system according to claim 1 is a gaming machine controlled by a game control device having a computer for gaming machines having a communication function with the outside and capable of appropriate inspection by an inspection signal.

It is characterized by determining whether it is reliable based on whether it satisfy | fills.

  According to a fourth aspect of the present invention, in the gaming machine inspection system according to the first aspect, the inspection signal determination means includes a first inspection command signal transmitted from the inspection device to the gaming machine computer. It is determined that the proper inspection of the gaming machine computer is reliable by satisfying the determination condition and the inspection response signal transmitted from the gaming machine computer that has received the inspection command to the inspection device satisfies the predetermined second determination condition. It is characterized by doing.

  According to the gaming machine inspection system according to claim 1, the gaming machine is acquired by the inspection signal acquisition unit capable of acquiring the inspection signal exchanged between the inspection device and the gaming machine computer, and the inspection signal acquisition unit. An inspection signal determination means for determining whether or not the appropriate inspection of the gaming machine computer is reliable based on the inspection signal, and a determination result notification means for informing the determination result of the inspection signal determination means, Since the inspection signal determination means is provided integrally with the electric / electronic components constituting the game control device, it can be determined by the function of the inspection signal determination means whether the appropriate inspection of the computer for the gaming machine is reliable. When an electrical / electronic component with an integrated means is replaced with an unauthorized part, the determination result notification means does not notify the appropriate determination result. It is possible to know the illegal tampering with the game controller.

  According to the gaming machine inspection system according to claim 2, is the inspection signal determination means reliable based on whether or not a transmission signal transmitted from the inspection device to the gaming machine computer satisfies a predetermined determination condition? Therefore, it is possible to determine by the inspection signal determination means that the proper inspection of the gaming machine computer is unreliable because the inspection device is illegal.

  According to the gaming machine inspection system according to claim 3, is the inspection signal determination means reliable based on whether or not a transmission signal transmitted from the gaming machine computer to the inspection device satisfies a predetermined determination condition? Therefore, it is possible to determine by the inspection signal determination means that the proper inspection of the gaming machine computer is unreliable because the gaming machine one-chip CPU is illegal.

  According to the gaming machine inspection system according to claim 4, the inspection signal determination means receives the inspection command when the inspection command signal transmitted from the inspection apparatus to the gaming machine computer satisfies a predetermined first determination condition. When the inspection response signal transmitted from the gaming machine computer to the inspection device satisfies the predetermined second determination condition, it is determined that the proper inspection of the gaming machine computer is reliable. Whether one of the chip CPUs is illegal or both the inspection device and the gaming machine one-chip CPU are illegal, the inspection signal determining means can strictly determine that the proper inspection of the gaming machine computer is not reliable. .

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows the overall configuration of a gaming machine inspection system. A gaming machine computer (ROM) that controls the gaming machine control board 2 by connecting an inspection device 3 to the gaming machine control board 2 of the gaming machine 1. , RAM and CPU are integrated into a one-chip IC that is a one-chip IC for gaming machines), and an inspection is performed using an ID (unique identification information) assigned to the one-chip IC. When informing the inspection result, characters or the like are displayed on the display screen of the inspection apparatus 3, the blue lamp or the red lamp is lit or blinking, the sound is output from the speaker, or any other known existing Any notification method may be used.

  FIG. 2 is an exploded perspective view of the gaming machine control device 20 provided in the gaming machine 1, and the gaming machine control board 2 is housed in a storage case formed by a first storage member 2 a and a second storage member 2 b formed of transparent resin. Is stored in the gaming machine control device 20. Various electrical / electronic components are mounted on the gaming machine control board 2 that can be visually recognized from the first and second storage members 2a and 2b. In FIG. 2, the gaming machine control board 2 is for gaming machines that control the main game. A one-chip CPU 21, an inspection terminal 22 for relaying communication between the one-chip CPU 21 for gaming machines and the inspection device 3, an I / O port 23 having an integrated circuit configuration including a plurality of input / output channels, various sensors, various devices, etc. Only the connector part 24 for connecting the signal lines is shown.

  Further, when the gaming machine control board 2 is stored by the first and second storage members 2a and 2b, at least the inspection terminal 22 and the connector portion 24 are exposed outside the case, so that the outside of the game control device 20 Can be connected. Further, when fixing the first storage member 2a and the second storage member 2b, it is desirable to adopt a fixing structure that cannot be easily re-separated. By leaving a trace separating the two storage members 2b, it may be used as a measure of whether or not the gaming machine control board 2 has been tampered with.

  FIG. 3 shows the internal configuration of the gaming machine 1, and the one-chip CPU 21 for gaming machines mounted on the gaming machine control board 2 communicates with the testing device 3 via the testing terminal 22, and I / O port 23 is connected to a plurality of input / output channels such as A channel 23a, B channel 23b, C channel 23c, D channel 23d, etc., and these A to D channels 23a to 23d are provided in gaming machine 1. Sensor 4 (various switches, detectors, etc. that represent two ON / OFF states by signal level), display control device 5 for controlling the display device, and game media discharge device for discharging game media (pachinko balls and medals) Connected to the discharge control device 6 that controls the sound, the effect control device 7 that performs the effect control by outputting the sound effect from the speaker, the light emission control of various display lamps, and the like To have.

  The inspection device 3 connected to the gaming machine one-chip CPU 21 via the inspection terminal 22 communicates with the gaming machine one-chip CPU 21 by an undisclosed communication protocol, and the ID assigned to the gaming machine one-chip CPU 21. The authenticity is determined based on (unique identification information). In the present embodiment, the appropriate determination of the gaming machine one-chip CPU 21 is performed by transmitting a predetermined inspection command from the inspection device 3 to the gaming machine one-chip CPU 21, and the gaming machine one-chip CPU 21 having received the inspection command responds to the command. A predetermined inspection response is transmitted to the inspection device 3, and the inspection device 3 that has received this inspection response determines the suitability of the one-chip CPU 21 for gaming machines based on the inspection response. It should be noted that the inspection device 3 can be handled only by a person who is apparently not fraudulent like a police officer. The inspection device 3 is disassembled and analyzed, or the inspection device 3 and the one-chip CPU 21 for gaming machines. The communication between the test command and the test response is kept confidential.

  Accordingly, the I / O port 23 is provided with an inspection signal determination means 25 independent of the plurality of channels 23a to 23d, and a signal line connecting the gaming machine one-chip CPU 21 and the inspection terminal 22 is branched. As a result, an inspection signal acquisition line L1 is formed as an inspection signal acquisition means capable of acquiring an inspection signal exchanged between the inspection device 3 and the one-chip CPU 21 for gaming machines, and the inspection is performed via the inspection signal acquisition line L1. The signal is supplied to the inspection signal determination means 25. The inspection signal determination means 25 determines whether or not the proper inspection of the one-chip CPU 21 for gaming machines is reliable based on the inspection signal, and the result is used to notify the determination result via the determination result output line L2. The determination result of the inspection signal determination means 25 can be visually recognized from the lighting state of the LED 26.

  The inspection signal determination means 25 provided inside the I / O port 23 includes an inspection command from the inspection device 3 to the gaming machine one-chip CPU 21, and an inspection response from the gaming machine one-chip CPU 21 to the inspection device 3. Is not output to the inspection device 3 or the one-chip CPU 21 for gaming machines, and therefore does not affect the signals exchanged between the inspection device 3 and the one-chip CPU 21 for gaming machines. In addition, there is an advantage that it is not necessary to change the inspection method of the conventional one-chip CPU 21 for gaming machines using the inspection device 3. In addition, since the inspection signal determination means 25 is independent of any channel inside the I / O port 23, the operation of the inspection signal determination means 25 does not affect the game control operation and is in the game. Even if it exists, it is possible to determine the suitability by the inspection signal determination means 25.

  In the present embodiment, the determination result notification means for notifying the determination result of the inspection signal determination means 25 is a visual notification using the determination result output line L2 and the LED 26. You may employ | adopt suitably the well-known existing alerting | reporting method. For example, a loudspeaker or an electronic buzzer provided on the gaming machine control board 2 may be sounded to audibly notify.

  Next, a specific example of the determination operation by the inspection signal determination unit 25 will be described. The flowchart of FIG. 4 shows a first configuration example of determination operation processing performed by the inspection signal determination unit 25.

  When a determination operation by the inspection signal determination unit 25 is started based on power-on or reset operation of the gaming machine, first, the display output of the LED 26 is cleared (step S11), and the signal of the inspection signal acquisition line L1 is monitored. Then, it is determined whether or not an inspection command from the inspection device 3 to the one-chip CPU 21 for gaming machines has been received (step S12). If it is determined that the inspection command has been received, it is determined whether or not the received inspection command is “01h” meaning an appropriate command (step S13).

  When the inspection device 3 inspects the gaming machine one-chip CPU 21, as shown in FIG. 5, a first determination condition in which an appropriate inspection command 01 h is first transmitted from the inspection device 3 to the gaming machine one-chip CPU 21. If the second determination condition in which an appropriate inspection response 02h is returned within a predetermined time from the one-chip CPU 21 for a gaming machine that has received this appropriate inspection command 01h to the inspection device 3 is achieved. The result becomes normal (see FIG. 5A). On the other hand, when an appropriate inspection command 01h is not transmitted from the inspection device 3 to the gaming machine one-chip CPU 21, an abnormal inspection response 03h is transmitted from the gaming machine one-chip CPU 21 to the inspection device 3. (See FIG. 5B), the result of the gaming machine inspection is also abnormal. And the determination operation | movement by the test | inspection signal determination means 25 is also performed along the test | inspection conditions of the test | inspection apparatus 3 and the one-chip CPU21 for game machines.

  In step S13, if the received inspection command does not correspond to “01h”, the process returns to step S12 to monitor the reception of the inspection command. As described above, when the inspection device 3 is an unauthorized device that does not transmit an appropriate inspection command, the display of the LED 26 remains cleared. Therefore, the inspection device 3 performs an appropriate inspection of the one-chip CPU 21 for gaming machines. It is determined that it is not reliable.

  On the other hand, if it is determined in step S13 that the received command corresponds to “01h”, an inspection response is returned from the one-chip CPU 21 for gaming machines that has received the appropriate inspection command 01h to the inspection device 3. A response monitoring timer for measuring a time necessary and sufficient to be set is set (step S14), and it is determined whether or not an inspection response transmitted from the gaming machine one-chip CPU 21 to the inspection device 3 is received (step S15). ).

  If it is determined in step S15 that an inspection response has not been received, it is determined whether or not the response monitoring timer set in step S14 has expired (step S16). If not, the process returns to step S15 to continue monitoring the inspection response.

  If it is determined in step S16 that the response monitoring timer has timed out without confirming reception of the inspection response, the process returns to step S12 again to monitor reception of the inspection command. Thus, when the inspection response signal is not transmitted from the one-chip CPU 21 for the gaming machine to the inspection device 3 within a predetermined time, the display of the LED 26 remains cleared. It is determined that the proper inspection of the CPU 21 is not reliable.

  If it is determined in step S15 that an inspection response has been received, it is determined whether the inspection response is “02h” meaning an appropriate response (step S17), and the inspection response is “02h”. If it is determined that it does not correspond to "", the process returns to step S12 again to monitor the reception of the inspection command. Thus, when the appropriate inspection response signal 02h is not transmitted from the gaming machine one-chip CPU 21 to the inspection device 3, the display of the LED 26 remains cleared. It is determined that the proper inspection is not reliable.

  On the other hand, if it is determined in step S17 that the received inspection response is “02h”, a display signal is output via the determination result output line L2, and the LED 26 is normally displayed (for example, in a lit state). (Step S18). As described above, the inspection signal determination unit in the gaming machine 1 according to the present embodiment evaluates an appropriate combination of the inspection command and the inspection response, and the gaming machine inspection is reliable only when the combination is correct. Since the determination result is output, the reliability can be strictly determined even when either the inspection device or the one-chip CPU for gaming machine is inappropriate.

  Further, since the inspection command transmitted by the inspection device 3 and the inspection response transmitted by the one-chip CPU 21 for gaming machines are non-public protocols as described above, the reliability of such a specific combination of communication is appropriately evaluated. However, the inspection signal determination means 25 that can display the result on the LED 26 can be manufactured only by the manufacturer of the one-chip CPU 21 for gaming machines. It can be determined that the I / O port 23 provided is manufactured by the same manufacturer as the manufacturer of the one-chip CPU 21 for gaming machines.

  That is, the suitability of the inspection signal determination means 25 itself can be determined from the determination status of the inspection signal determination means 25 with respect to the inspection of the gaming machine one-chip CPU 21 by the inspection device 3.

  More specifically, based on FIG. 6, the I / O port of the gaming machine control board 2 is replaced with an unauthorized I / O port 23 ', and the unauthorized I / O port is switched from a regular gaming machine one-chip CPU 21. If tampering is performed to cut the connection line to 23 ', the illegal one-chip CPU 21' in the I / O port 23 'will be an illegally modified machine in which actual gaming machine control is performed. In the CPU inspection by the inspection device 3 connected in this manner, since an appropriate response is obtained from the genuine one-chip CPU 21 for gaming machines, the inspection result in the inspection device 3 becomes normal, whereas Since the inspection signal determining means 25 is not provided in the / O port 23 ', an appropriate determination result is not displayed on the LED 26, that is, the I / O port is not a genuine product. You can know that it is subjected to tampering with respect to skills unit control board 2.

  It is also expected that a dummy inspection signal determination means is provided in the illegal I / O port 23 'so that when the potential change that seems to be an inspection signal is detected from the inspection signal acquisition line L1, unauthorized alteration such as turning on the LED 26 is expected. Is done. However, if it is not the manufacturer of the one-chip CPU 21 for gaming machines, the suitability of the inspection signal cannot be determined. Therefore, when an abnormal inspection command is intentionally transmitted from the inspection device 3, the LED 26 is lit (normal determination output). In such a case, it can be clearly determined that the inspection signal determination means 25 itself has been tampered with.

  As described above, if the inspection signal determination means 25 is provided in the I / O port 23, whether the proper inspection of the one-chip CPU 21 for gaming machines using the inspection device 3 can be trusted by the function of the inspection signal determination means 25. In addition to being able to make a determination, when the I / O port 23, which is an electrical / electronic component integrally provided with the inspection signal determination means 25, is replaced with an unauthorized component, an appropriate determination result is notified by the LED 26. By not being present, it is possible to know unauthorized tampering with the game control device 20.

  The electrical / electronic component provided with the inspection signal determination means 25 is not limited to the I / O port 23, and may be, for example, a serial communication interface or a transistor array. However, it is desirable that the inspection signal determination means function independently of the functions of these components. Further, the inspection signal determination means 25 only monitors the inspection signal and does not output any signal. Even if the number of branches of the inspection signal acquisition line L1 for acquiring the inspection signal is increased, the inspection apparatus 3 and the gaming machine The signal exchanged with the one-chip CPU 21 is not affected, so that a plurality of electrical / electronic components are provided with inspection signal determination means 25, and the inspection signal determination means 25 of each component individually performs the determination operation. Also good.

  In the first configuration example of the determination operation process performed by the inspection signal determination unit 25 described above, the first determination condition and the second determination conform to the inspection performed between the inspection device 3 and the gaming machine one-chip CPU 21. Although it is determined that the gaming machine inspection is reliable when two of the conditions are achieved, the determination operation by the inspection signal determination unit 25 may be simpler.

  For example, a process in which the test signal determined by the test signal determination unit 25 is only the test command (second configuration example of the determination operation process performed by the test signal determination unit 25) will be described based on the flowchart of FIG.

  When a determination operation by the inspection signal determination unit 25 is started based on power-on or reset operation of the gaming machine, first, the display output of the LED 26 is cleared (step S21), and the signal on the inspection signal acquisition line L1 is monitored. While waiting for reception of the inspection command from the inspection device 3 to the one-chip CPU 21 for gaming machines. When an inspection command is received from the inspection signal acquisition line L1 (step S22), it is determined whether or not the received inspection command is “01h” meaning an appropriate command (step S23).

  If it is determined in step S23 that the inspection command does not correspond to “01h”, the process returns to step S22 to monitor reception of the inspection command. As described above, when the proper inspection command signal 01h is not transmitted from the inspection device 3 to the gaming machine one-chip CPU 21, the display of the LED 26 remains cleared. It is determined that the proper inspection is not reliable.

  On the other hand, if it is determined in step S23 that the received inspection command is “01h”, a display signal is output via the determination result output line L2, and the LED 26 is normally displayed (for example, in a lit state). (Step S24). As described above, the inspection signal determination means 25 of this configuration example compares the inspection command received via the inspection signal acquisition line L1 with the appropriate inspection command, and only when the inspection command matches the appropriate inspection command. The determination result that the inspection is reliable is output.

  When an inspection command deviating from the inspection protocol of the gaming machine one-chip CPU 21 is input from the inspection device 3, the gaming machine one-chip CPU 21 does not respond to the reception of an abnormal inspection command. Alternatively, a response indicating that the communication is not normal is made. However, when the inspection signal determination unit 25 performs the determination operation processing as in this configuration example, only the inspection command is the basis for the determination. There is an advantage that it is not affected by the response operation of the one-chip CPU 21 and can respond to either response. In addition, since there is no correlation between the inspection protocol of the gaming machine one-chip CPU 21 and the inspection command that the inspection signal determination means 25 determines normally, it affects the confidentiality of the inspection of the gaming machine one-chip CPU 21. There is an advantage that it is not a thing.

  Next, processing (third configuration example of determination operation processing performed by the inspection signal determination unit 25) in which the inspection signal determined by the inspection signal determination unit 25 is only the inspection response will be described based on the flowchart of FIG.

  When determination operation by the inspection signal determination means 25 is started based on power-on or reset operation of the gaming machine, first, the display output of the LED 26 is cleared (step S31), and the signal on the inspection signal acquisition line L1 is monitored. While waiting for reception of the inspection response from the one-chip CPU 21 for gaming machines to the inspection device 3. When an inspection response is received from the inspection signal acquisition line L1 (step S32), it is determined whether or not the received inspection response is “02h” meaning an appropriate response (step S33).

  When it is determined in step S33 that the inspection response does not correspond to “02h”, the process returns to step S32 again to monitor reception of the inspection response. As described above, when the proper inspection response signal 02h is not transmitted from the inspection device 3 to the gaming machine one-chip CPU 21, the display of the LED 26 remains cleared. It is determined that the proper inspection is not reliable.

  On the other hand, if it is determined in step S33 that the received inspection response is “02h”, a display signal is output via the determination result output line L2, and the LED 26 is normally displayed (for example, in a lit state). (Step S34). As described above, the inspection signal determination unit 25 of this configuration example compares the inspection response received via the inspection signal acquisition line L1 with the appropriate inspection response, and only when the inspection response matches the appropriate inspection response. The determination result that the inspection is reliable is output.

  When the inspection signal determination means 25 performs the determination operation processing as in this configuration example, only the inspection response is the basis for determination, so that the one-chip CPU 21 for gaming machines makes a predetermined inspection response regardless of the inspection command. Whether or not the CPU test is reliable can be determined only by whether or not it is.

  When an inspection command deviating from the inspection protocol of the gaming machine one-chip CPU 21 is input from the inspection device 3, the gaming machine one-chip CPU 21 is not in a normal communication with respect to receiving an abnormal inspection command. In a gaming machine inspection system set to perform a response (for example, 04h), the inspection signal determination means 25 can identify and determine whether the inspection response matches "02h" and "04h" When the inspection response matches “02h”, the green lamp is turned on. When the inspection response matches “04h”, the yellow lamp is turned on, and both the inspection responses are “02h” and “04h”. If you do not do so, set the red lamp to light up. If the green lamp lights up, the inspection device 3 and the gaming machine Both the one-chip CPUs 21 can be informed that they are normal, and when the yellow lamp is lit, the gaming machine one-chip CPU 21 can be informed that the inspection device 3 is appropriate, but at least the gaming machine one-chip CPU 21 is lit by lighting the red lamp. Can be informed that is illegal.

  As mentioned above, although the embodiment of the gaming machine inspection system according to the present invention has been described in detail based on the accompanying drawings, the present invention is not limited to this, unless the configuration described in the claims is changed. It can be realized by employing various equivalent technologies.

  For example, the above-described inspection signal determination means 25 clears the LED 26 once the determination is started, turns on the LED when the determination result is appropriate, and keeps the LED off when it is incorrect. The two determination results correspond to different display modes. However, the present invention is not limited to this, and the LED that was in the lighting state at the time of the inspection signal is turned off along with the appropriate determination, and is turned off at the time of the inspection signal determination. If the determination result is appropriate, a display method of changing the display mode to the other may be adopted so that the LED that has been determined to be turned on with appropriate determination.
