[Technical Field]

[0001] The present invention relates to a gaming machine. [Background technology]

[0002] 2. Description of the Related Art Gaming machines such as pachinko machines are known in which games are played using gaming balls as gaming media. In amusement halls, game balls are supplied to gaming machines from island equipment, but as they circulate between the island equipment and the gaming machines, they rub against each other and become charged with static electricity. This static electricity can cause electrostatic noise, which can affect the operation of the performance control device. In addition, noise generated by other gaming machines placed opposite each other can cause disturbances and affect the operation of the performance control device located behind the gaming machine. In addition, statically charged players or gaming hall staff can touch the gaming machine and affect its operation. For this reason, various technologies are used in gaming machines to reduce the effects of electrostatic noise (Patent Document 1). As a related technique, a resistance evaluation device that evaluates the resistance of semiconductor elements, including performance control devices, is known (Patent Document 2).

[0004] However, even if countermeasures are taken, malfunctions due to static electricity may not be avoided in the performance control devices installed in gaming machines, so at the development site of gaming machines, it is necessary to develop programs on the assumption that the performance control device will malfunction due to static electricity. As a result, there is a demand to know which processing in the performance control device is affected by electrostatic noise and causes the malfunction. To achieve this, it is possible to equip the performance control device with a function to output a status log indicating program malfunctions, and connect a measurement device to the performance control device via a cable.When electrostatic noise is applied to the performance control device using an electronic gun, the status log indicating program malfunctions caused by the influence of electrostatic noise can be monitored via the cable with the measurement device.However, the flow of electrostatic noise to the performance control device is different from the environment in an amusement hall where cables and measurement devices are not connected to the performance control device.

[0005] That is, electrostatic noise from the electronic gun is also applied to the cable. As a result, in the performance control device, not only is electrostatic noise from the electronic gun present, but also electrostatic noise transmitted through the cable can cause program malfunctions, which are reflected in the status log. From such a status log, it is impossible to determine which processing in the performance control device was affected by the electrostatic noise in the gaming hall, causing the malfunction. Furthermore, because the electrostatic noise affects the measurement device via the cable, the measurement device may not be able to properly acquire the status log. For these reasons, it has traditionally been difficult to accurately test the effect of electrostatic noise on the processing of performance control devices. One aspect of the present invention is to enable accurate testing of the effect of electrostatic noise on the processing of a performance control device. [Means for solving the problem]

[0006] In one aspect, the present invention provides gaming machines A performance control device that controls the performance Electrostatic test system used for electrostatic tests And, The electrostatic testing system includes a cable device, the performance control device, and a measurement device, The cable device includes: A communication path used during the electrostatic test, which connects the performance control device and the measurement device so that they can communicate with each other, Connected Cables and wiring The first isolation circuit provides insulation and isolation between the and wiring a second isolation circuit that insulates and separates the first isolation circuit and the second isolation circuit; a cable that connects the first isolation circuit and the second isolation circuit; a first wiring that connects the performance control device and the first isolation circuit; and a second wiring that connects the second isolation circuit and the measurement device. The first isolation circuit insulates the cable from the first wiring, preventing the effects of electrostatic noise applied to the cable from reaching the performance control device; the second isolation circuit insulates the cable from the second wiring, preventing the effects of electrostatic noise applied to the cable from reaching the measuring device; when electrostatic noise radiated by a noise generating source used for the electrostatic test is applied, the performance control device creates an error content caused by the electrostatic noise applied directly from the noise generating source without being affected by the electrostatic noise applied to the cable, and outputs the created error content to the measuring device via the cable device; and the measuring device acquires the error content without being affected by the electrostatic noise applied to the cable.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a gaming machine according to this embodiment. As shown in FIG. 1, the gaming machine 10 includes a main control board 1A, a performance control board 2A, a storage device 3, a display device 4, a sound emitting device 5, a lighting device 6, and a drive device 7. The main control board 1A is equipped with a main control device 1 (main CPU). The performance control board (sub-board) 2A is equipped with a performance control device 2 (sub-CPU). The gaming machine 10 is, for example, a pachinko gaming machine in which a game is played using gaming balls as a gaming medium. The main control board 1A and performance control board 2A, the performance control board 2A and storage device 3, and the performance control board 2A, display device 4, sound emission device 5, lighting device 6, and drive device 7 are all connected so that they can communicate with each other. However, communication between the main control board 1A and performance control board 2A is one-way communication, which only allows commands to be input from the main control board 1A to the performance control device 2. It is not possible to input data or commands from the performance control device 2 to the main control board 1A.

[0010] When the gaming machine 10 is a pachinko gaming machine, when the gaming medium shot out into the gaming area by the launching device enters a starting winning hole provided in the gaming area, the main control device 1 draws a pattern using random numbers and determines whether or not there is a jackpot based on the result of this drawing. The main control board 1A outputs a command to the performance control device 2 to specify the time and pattern of symbol variation based on the result of the jackpot determination. Alternatively, if no start winning occurs for a certain period of time, the main control board 1A puts the gaming machine 10 into a customer waiting state (standby state) and inputs a command to the performance control device 2 indicating that the gaming machine has entered the customer waiting state. If a jackpot is determined in the jackpot determination, after the change of the symbols has finished, the game medium enters the opened attacker, and the jackpot is awarded, with prize balls being paid out.

[0011] The performance control device 2 selects a performance to be performed using performance devices such as a display device 4, a sound emitting device 5, a lighting device 6, and a driving device 7 based on commands input from the main control board 1A, and controls the execution of the selected performance or a performance while customers are waiting during a specified variable time. The display device 4 is, for example, a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or an OLED (Organic Light Emitting Diode). The sound emitting device 5 is, for example, a speaker. The lighting device 6 is, for example, a light-emitting device such as an LED (Light Emitting Diode). The driving device 7 is a motor that drives the performance props. The storage device 3 stores image data, sound data, and lighting data used for game effects, customer waiting effects (standby effects), and effects during a big win. The image data includes moving image data.

[0012] The performance control device 2 reads data from the storage device 3 based on commands input from the main control board 1A, and performs various processes on the read data. The performance control device 2 performs drawing processing on the read image data and outputs the data to the display device 4 to display the image. The performance control device 2 also performs playback processing on the read audio data and outputs the data to the sound emitting device 5 to output the audio. Furthermore, the performance control device 2 outputs the read lighting data to the lighting device 6 to light the lamp. The performance control device 2 outputs the processed drive data to the drive device 7, causing the drive device 7 to rotate the motor.

[0013] FIG. 2 is a diagram illustrating the configuration of the electrostatic testing system according to this embodiment. The electrostatic testing system 100 of this embodiment includes the performance control device 2 of the gaming machine 10, a PC (Personal Computer) 30, an electronic gun 40, and a cable device 20 (communication path). The electronic gun 40 is an electrostatic noise generating source for applying static electricity to the performance control device 2. Gaming machines installed in amusement halls are subject to static noise caused by various factors, which acts as a disturbance and affects the operation of the presentation control device 2. Disturbances can occur, for example, due to static electricity generated when gaming balls rub against each other as they circulate between the island equipment and the gaming machine, or noise generated by other gaming machines placed opposite. Another cause of disturbances can be a statically charged player or amusement hall staff touching a gaming machine. The electrostatic noise applied to the presentation control device 2 by the electronic gun 40 for static electricity testing can reproduce such disturbances caused by static electricity in amusement halls.

[0014] The electrostatic test system 100 is a system that performs an electrostatic test on a performance control device 2, and the performance control device 2 is a board under test in the electrostatic test system 100. After an error occurs in an internal process, the performance control device 2 can create and output a situation log that includes the type of error that occurred and the registers that were required. In other words, the situation log indicates any problems or malfunctions in the processes or programs executed by the performance control device 2. The status log created by the performance control device 2 in response to electrostatic noise from the electronic gun 40 specifically indicates which parts of the performance control device 2's processing or program the electrostatic noise has affected, causing malfunctions or errors. The status log has, for example, the following contents: [2023-07-06 14:24:19.674] !!### EDI BUS ERROR ##### CCTLINTSTAT2:00000040 ### [2023-07-06 14:24:19.674] ECCSTAT:0x00010158 ECCERRCNT:0x07ee0226 CCTLINTCTRL2:00000040 CCTLINTSTAT2:00000040 ECCCFG0:033f7f44 [2023-07-06 14:24:19.674] ERR agDraw failed (Draw error in IDX operations) When static electricity is applied by the electronic gun 40, the performance control device 2 creates a situation log indicating the influence of the electrostatic noise after the influence of the electrostatic noise has subsided, and outputs the log to the cable device 20.

[0015] The PC 30 is a measurement device that can acquire the status log transmitted from the performance control device 2 via the cable device 20 and display it on a display device provided in the PC 30. The status log acquired by the PC 30 contains more detailed information than simply information indicating that an error has occurred due to electrostatic noise. Therefore, the person conducting the test or the developer of the gaming machine can refer to the status log displayed on the PC 30 and quickly make corrections to the program of the performance control device 2 to address the error due to static electricity. For example, it is conceivable that the status log obtained as a result of the electrostatic test indicates that image data could not be loaded from the external storage device 3 and therefore could not be displayed on the display device 4. In this case, the developer or the like can modify the program so that if the image data cannot be loaded within a certain time, the program retries loading the image data, increases the number of retries, or lengthens the waiting time. If the status log indicates an error that cannot be resolved by retrying the load, such as a problem with communication with the external storage device 3, the developer may modify the program to restart the image processing process in the performance control device 2 or the performance control device 2 itself. By modifying the program to be incorporated into the performance control device 2, the gaming machine 10 in operation in the gaming hall, i.e., in the real environment, can continue to operate by taking appropriate measures even if an error occurs due to electrostatic noise. For example, even if the gaming machine 10 is unable to load image data from the external storage device 3 due to the effects of electrostatic noise, it can immediately retry the load and display the image normally, or by restarting the performance control device 2, it can resolve communication problems with the external storage device 3 and minimize the period of time during which the screen display on the display device 4 is blacked out.

[0016] The cable device 20 will now be described. Cable device 20 connects performance control device 2 and PC 30, and transmits a status log output from performance control device 2 to PC 30. Cable device 20 includes a cable 24, a first insulation circuit 21, a second insulation circuit 22, a first wiring 25, a second wiring 26, and a power supply 23 that supplies power to first insulation circuit 21 and second insulation circuit 22. As will also be described in Figures 5 and 6, power is supplied to first insulation circuit 21 via a board on which second insulation circuit 22 is mounted. For reasons explained below, it is desirable that the cable 24 be a serial cable, and hereinafter the cable 24 will be referred to as a serial cable 24 .

[0017] The electrostatic testing system 100 is characterized by the cable device 20, which implements two-stage insulation measures (first insulation circuit 21, second insulation circuit 22) between the performance control device 2 and the PC 30. As a result, the electrostatic testing system 100 enables the PC 30 to normally receive a status log that reflects the effects of electrostatic noise on gaming machines in an amusement hall (real environment).

[0018] Before describing in detail the electrostatic test system 100 equipped with the cable device 20, a comparative example will be considered using FIG. 3 in which the performance control device 2 and the PC 30 are connected by a different cable 50 for the electrostatic test. The cable 50 is, for example, a USB (Universal Serial Bus) cable or other serial cable, and unlike the serial cable 24 of the cable device 20 in Figure 2, no insulation measures are taken between the performance control device 2 and the PC 30 and the cable 50.

[0019] FIG. 3 is a diagram illustrating a comparative example in which a performance control device and a PC are connected without any insulation measures. In FIG. 3, only the cable 50 and the cable device 20 are different, and the basic configuration, such as the performance control device 2 having a situation log output function, is the same as in FIG. No insulation measures are taken for the cable 50 between the performance control device 2 and the PC 30, and a status log for the performance control device 2 when electrostatic noise is applied is output from the performance control device 2 via the cable 50 and monitored by the PC 30.

[0020] 3 has the following problem: When a cable 50 is connected to the performance control device 2 and static electricity is applied to the performance control device 2 using the electronic gun 40, some of the electrostatic noise generated by the electronic gun 40 may be applied to the cable 50. The performance control device 2 creates and outputs a situation log after the effects of the electrostatic noise have subsided. Therefore, it is unlikely that the situation log data will be corrupted during the communication process from when the situation log is output from the performance control device 2 until it is input to the PC 30. However, if electrostatic noise applied to the cable 50 is transmitted to the PC 30, it may cause the PC 30 to malfunction and prevent the PC 30 from properly acquiring the situation log. Furthermore, the effects of not only the electrostatic noise transmitted from the electronic gun 40 but also the electrostatic noise applied to the cable 50 may be transmitted to the performance control device 2. As a result, in the performance control device 2, problems or malfunctions may occur in the programs or processing due to not only the electrostatic noise transmitted directly from the electronic gun 40 but also the electrostatic noise applied to the cable 50. In this case, the status log created by the performance control device 2 will also record program and processing malfunctions and errors caused not only by the electrostatic noise transmitted from the electronic gun 40 but also by the electrostatic noise transmitted from the cable 50.

[0021] Originally, the static electricity testing system 100 was intended to test for malfunctions of the performance control device 2 caused by disturbances that occurred while the gaming machine 10 was in operation in an amusement hall. In a real environment, the cable 50 is not connected to the gaming machine 10, and therefore malfunctions caused by static electricity applied to the cable 50 do not occur. In the electrostatic testing system 100 shown in Figure 3, the flow of electrostatic noise to the performance control device 2 is different from that in an amusement hall environment where the cable 50 and PC 30 are not connected to the performance control device 2. Therefore, the status log acquired from the performance control device 2 in Figure 3 does not reflect the effect of electrostatic noise on gaming machines in a real environment. From such a status log, it is not possible to know which process in the performance control device 2 has malfunctioned or failed due to the electrostatic noise in the amusement hall. The errors and malfunctions that occur in the performance control device 2 will differ depending on whether the cable 50 is connected to the PC 30 or not. Furthermore, electrostatic noise may affect the PC 30 via the cable 50, which may prevent the PC 30 from properly acquiring the status log.

[0022] Therefore, the electrostatic testing system 100 implements the two-stage insulation measures described below in the cable device 20 so that the PC 30 can normally receive a status log from the performance control device 2 that reflects the impact of electrostatic noise on the gaming machine 10 in a real environment.

[0023] First, as explained in FIG. 2, the cable device 20 inserts a first insulating circuit 21 and a second insulating circuit 22 between the serial cable 24 and the performance control device 2 and between the serial cable 24 and the PC 30, respectively. Furthermore, the cable device 20 connects the first insulating circuit 21 (first insulating circuit board 21A described below) and the performance control device 2 with a first wiring 25. The cable device 20 also connects the second insulating circuit 22 (second insulating circuit board 51 described below) and the PC 30 with a second wiring 26. It should be noted that part or all of the first wiring 25 may be printed wiring on the performance control board 2A on which the performance control device 2 is mounted, rather than being a cable. If the first wiring 25 includes a cable, the cable is a serial cable. If, for example, a parallel cable is used instead of a serial cable, the number of cables increases and the cable becomes more susceptible to electrostatic noise. In addition, a parallel cable is difficult to attach to the performance control device 2.

[0024] FIG. 4 is a diagram illustrating a connection mode of the first wiring to the performance control device on the performance control board. If all of the first wiring 25 is a cable, the cable is soldered directly to the output terminal of the performance control device 2 on the performance control board 2A or in the vicinity thereof, as shown in Fig. 4(a). If part of the first wiring 25 is a printed wiring, the cable is soldered to the printed wiring drawn out from the performance control device 2, as shown in Fig. 4(b). Alternatively, the first wiring 25 is connected to a connector provided on the performance control board 2A for the printed wiring drawn out from the performance control device 2. Furthermore, if the entire first wiring 25 is printed wiring, as shown in Figure 4(c), the first isolation circuit 21 is mounted directly on the performance control board 2A, and the performance control device 2 and the first isolation circuit 21 are connected by printed wiring. In the case of FIG. 4(a), the length of the cable is the length of the first wiring 25, and in the case of FIG. 4(b), the length of the first wiring 25 is the combined length of the cable and the printed wiring. As shown in Figure 4(c), if the first insulating circuit 21 is mounted directly on the performance control board 2A, the first wiring 25 becomes entirely printed wiring, which makes it possible to more effectively suppress the effects of electrostatic noise on the first wiring 25. However, there are cases where it is desirable for the first wiring 25 to include a cable portion of a certain length, such as when pulling out the first wiring 25 from the board case that houses the performance control board 2A during electrostatic testing.

[0025] Whether first wiring 25 is realized by cable only or first wiring 25 is partially or entirely made of printed wiring, first wiring 25 should be as short as possible overall. If first wiring 25 is long, even if first insulation circuit 21 insulates first wiring 25 from serial cable 24, the effects of electrostatic noise applied to first wiring 25 may be reflected in the situation log created by performance control device 2. As with the state in which the first insulating circuit 21 described in Figure 3 is not installed, the status log created by the performance control device 2 will record program and processing malfunctions and errors caused not only by electrostatic noise transmitted directly from the electronic gun 40 but also by electrostatic noise transmitted from the first wiring. The errors and malfunctions that occur in the performance control device 2 will differ depending on whether the first wiring 25 is sufficiently short or not. The optimum length of the first wiring 25 is a length that can be drawn out from the board case and is not affected by electrostatic noise.

[0026] FIG. 5 is a circuit diagram showing a configuration for insulating the performance control device from the serial cable. The first insulating circuit 21, which provides insulation between the serial cable 24 and the first wiring 25 and therefore the performance control device 2, is mounted on a first insulating circuit board 21A. The performance control device 2 and the first isolation circuit 21 are connected by a first wiring 25. As shown in Fig. 5, the first wiring 25 connects between an open-drain buffer 41 and a pull-up resistor 42 mounted on the performance control board 2A. A commercially available optical isolation isolator (HCPL-260L manufactured by Broadcom) is used for the first isolation circuit 21 in Fig. 5. Any circuit configuration can be used for the first isolation circuit 21 as long as the serial cable 24 and the first wiring 25 are insulated from each other.

[0027] FIG. 6 is a circuit diagram showing a configuration for insulating the measurement device from the serial cable. The PC 30 and the board on which the second isolation circuit 22 is mounted are connected via a second wiring 26. The second wiring 26 is, for example, a USB (Universal Serial Bus) cable. By providing the second insulating circuit 22, it is possible to prevent electrostatic noise applied to the serial cable 24 from affecting the PC 30. For example, a digital isolator (ADUM121 manufactured by Analog Devices) that uses a transformer included in a commercially available isolated USB-serial converter is used as second isolation circuit 22. In other words, the isolated USB-serial converter is second isolation circuit board 51 on which second isolation circuit 22 is mounted. The signal output from the second insulating circuit 22 is converted into a USB signal by the signal converter 52 and output to the second wiring 26. As long as the serial cable 24 and the PC 30 are insulated from each other, any circuit configuration can be used for the second isolation circuit 22. It is also desirable to make the second wiring 26 as short as possible.

[0028] In the electrostatic testing system 100 of Figure 2, the performance control device 2 and the serial cable 24 are insulated by the first isolation circuit 21 as shown in Figure 5, so that the effects of electrostatic noise applied to the serial cable 24 can be prevented from reaching the performance control device 2. Furthermore, because the first wiring 25 between the performance control device 2 and the first insulating circuit 21 is made as short as possible, it is possible to ensure that the symptoms of phenomena caused by the effects of electrostatic noise applied to the performance control device 2 do not change regardless of the presence or absence of the first wiring 25. Furthermore, because the first wiring 25 is made as short as possible, it is possible to prevent the effects of electrostatic noise applied to the first wiring 25 from reaching the performance control device 2. Furthermore, by covering the first wiring 25, the influence of electrostatic noise applied to the first wiring 25 on the performance control device 2 can be further suppressed. Furthermore, as shown in FIG. 6, the second insulating circuit 22 insulates the PC 30 from the serial cable 24, thereby preventing the influence of electrostatic noise from reaching the PC 30. By providing the first insulating circuit 21 and the second insulating circuit 22, the serial cable 24 can be made to have any length, for example, a length that is sufficient for practical use.

[0029] Furthermore, an ungrounded power supply such as a battery is used for the power supply (3.3 V) 23 that drives the first insulation circuit 21 and the second insulation circuit 22. This prevents the effects of electrostatic noise applied to the power supply 23 from the electronic gun 40 during electrostatic testing from reaching the earth and affecting the performance control device 2 and PC 30. This prevents the effects of electrostatic noise applied to the power supply 23 from being reflected in the status log of the performance control device 2 and from affecting the operation of PC 30. 2 is provided and serial cable 24 is insulated immediately after being pulled out from performance control device 2, electrostatic noise applied to serial cable 24 will not affect performance control device 2. However, there is still a possibility that electrostatic noise received by serial cable 24 will cause PC 30 to malfunction. Furthermore, if both first insulation circuit 21 and second insulation circuit 22 are provided and serial cable 24 is insulated at two locations, immediately after being pulled out from performance control device 2 and immediately before being input to PC 30, it is possible to eliminate the effects of electrostatic noise on both performance control device 2 and PC 30. As a result, PC 30 of electrostatic testing system 100 can accurately obtain information on the status of performance control device 2 due to the effects of electrostatic noise.

[0030] The mechanism of insulation in the first insulation circuit 21 will be briefly explained with reference to FIGS. The first isolation circuit 21 is a photocoupler and includes an LED 21a and a NAND gate 21b. The light emission (ON / OFF) of the LED 21a and an enable signal (HIGH / LOW) are input to the NAND gate 21b. The NAND gate 21b determines the output signal (HIGH / LOW) from the first isolation circuit 21 by the following combination. TIFF0007822641000001.tif31144 A signal flows when the LED 21a is ON and the enable signal is not HIGH. There is no electrical connection between the LED and the NAND gate, so electrostatic noise from the cable 24 is not transmitted to the first wiring 25 and, ultimately, to the performance control device 2, thereby affecting it. 5 and 6, power is supplied to first insulation circuit 21 from battery 23 via second insulation circuit board 51. Therefore, second insulation circuit board 51 and first insulation circuit board 21A are connected by power cable 62. An enable signal is supplied to the first insulating circuit 21 from the battery 23 via the second insulating circuit board 51. Therefore, the second insulating circuit board 51 and the first insulating circuit board 21A are connected by a signal cable 63. The GND output of the first isolation circuit 21 is input to the GND terminal of the second isolation circuit board 51 via a GND cable 61 . Therefore, the second insulating circuit board 51 and the first insulating circuit board 21A are connected by a cable in which four cables, namely, the serial cable 24, the GND cable 61, the power cable 62, and the signal cable 63, are twisted together.

[0031] FIG. 7 is a diagram comparing the phenomena and processing of the performance control device when the performance control device and the measuring device are not insulated from the serial cable and when they are insulated. FIG. 7(a) corresponds to FIG. 3 and shows a case where the performance control device 2 and the measurement device (PC 30) are not insulated from the serial cable 50. (A) Electrostatic noise is applied to the performance control device 2 by the electronic gun 40. (B) A processing error occurs in the performance control device 2 due to electrostatic noise from the electronic gun 40 and the serial cable 50 that is not insulated from the performance control device 2 and PC 30. (C) After a certain period of time has passed, the effect of electrostatic noise on the performance control device 2 and serial cable 50 disappears. (D) The performance control device 2 creates a situation log that includes errors that have occurred due to errors caused by electrostatic noise from the electronic gun 40 and the cable 50. (E) The performance control device 2 outputs the situation log to the PC 30 using a cable 50 that is no longer affected by electrostatic noise.

[0032] FIG. 7(b) corresponds to FIG. 2 and shows a case where the performance control device 2 and the measurement device (PC 30) are insulated from the cable device (serial cable 24). (A) Electrostatic noise is applied to the performance control device 2 by the electronic gun 40. (B) The serial cable 24 is insulated from the performance control device 2 and the PC 30, and an error occurs in the performance control device 2 due to electrostatic noise from the electronic gun 40. (C) After a certain period of time has passed, the effect of electrostatic noise on the performance control device 2 and serial cable 24 disappears. (D) The performance control device 2 creates a status log that includes errors that have occurred in processing due to errors caused by electrostatic noise from the electronic gun 40. (E) The performance control device 2 outputs the status log to the PC 30 using the serial cable 24, which is no longer affected by electrostatic noise.

[0033] In the case of Figure 7(a), electrostatic noise from the electronic gun 40 applied to the serial cable 50, which is not insulated from the performance control device 2 and PC 30, affects the performance control device 2, preventing the performance control device 2 from creating an appropriate situation log. On the other hand, in the case of Figure 7(b), electrostatic noise from the electronic gun 40 applied to the serial cable 24, which is insulated from the performance control device 2 and PC 30, does not affect the performance control device 2, allowing the performance control device 2 to create an appropriate situation log that reflects only the effects of the electrostatic noise from the electronic gun 40. According to the electrostatic testing system 100 of this embodiment, it is possible to accurately inspect the effect that electrostatic noise in a real environment has on the processing of the performance control device 2 of the gaming machine 10, and corrections corresponding to errors can be quickly made to the program of the performance control device 2.

[0034] The cable device 20 of this embodiment can be used not only for electrostatic testing of the performance control device of a gaming machine. The cable device 20 can also be connected to the control unit of an embedded device or appliance product that is installed in an environment with strong electrostatic noise, and electrostatic testing can be performed. The results of the electrostatic test can then be used to improve the embedded program.
