One of these three signals is sent as an external signal 3 to an external device by the manufacturer of the rotary gaming machine. The external signal 4 is a signal for a continuous action device, a signal for replaying, or a signal for a normal accessory related to the second type special accessory. One of these three signals is sent as an external signal 4 to an external device by the manufacturer of the rotary gaming machine. In addition, in the swivel type gaming machine of this embodiment, the external signal 1 is a signal indicating that the first type special object is operating, the external signal 2 is a signal indicating that the continuous action device is related to the first type special character, and the external signal 3 Is a replaying signal, and the external signal 4 is a normal accessory signal.

  The external signal 5 is a fraud detection pulse signal, and in the present embodiment, the five fraud detection pulse signals described above are transmitted as the external signal 5. However, the present invention is not limited to this, and some of these fraud detection pulse signals may be included, or may be included when other fraudulent acts are detected. .

  In this embodiment, the medal insertion signal terminals CN1 (7), CN2 (1) and the individual interface circuits I1 (relays RY1, D1, ZNR1, LED1, R1) of the external concentration terminal board are formed by the player. When a medal is inserted into the gaming machine device, the medal insertion signal is sent to an external device. The medal payout signal terminals CN1 (6), CN2 (2) and the individual interface circuit I2 (relays RY2, D2, ZNR2, LED2, R2) are arranged so that when the rotary gaming machine device pays out a winning medal. This is for sending a pulse signal corresponding to the number of sheets to an external device. The external signal 1 terminals CN1 (5), CN2 (3) and the interface circuit I3 (relays RY3, D3, ZNR3, LED3, R3) are turned on when the gaming state is in operation of the first kind special object. This is for sending a signal to an external device. The external signal 2 terminals CN1 (4), CN2 (4) and the interface circuit I4 (relays RY4, D4, ZNR4, LED4, R4) are connected to the continuous action device in which the gaming state is related to the first kind special accessory. When this happens, an ON signal is sent to the external device.

  The external signal 3 terminals CN1 (3), CN2 (5) and the individual interface circuit I5 (relays RY5, D5, ZNR5, LED5, R5) send an ON signal to the external device when the game state is being replayed. To send to. Terminals CN1 (2), CN2 (7) for external signal 4 and interface circuit I6 (relays RY6, D6, ZNR6, LED6, R6) send an ON signal to the external device when the gaming state becomes a normal game. To send to. Terminals CN1 (1), CN2 (8) for external signal 5 and interface circuit I7 (relays RY7, D7, ZNR7, LED7, R7) detect fraud detected when external signal 5, for example, front door 2 is opened. This is for sending a pulse signal to an external device. Terminal CN2 (6) is a relay common of each relay.

  The external concentrated terminal plate 27 has seven relay contact outputs as described above, and the other terminal of each of the seven relay contacts becomes a relay common connected at one point, and this relay common is a terminal CN2 ( 6) to the external device. That is, the external concentration terminal plate 27 includes a total of eight output terminals, one terminal of seven relay contacts and one relay common terminal. Here, the terminal CN1 (1) is an unauthorized common input terminal of the present invention, and a pair of the terminal CN2 (8) and the terminal CN2 (6) is an unauthorized common output terminal of the present invention.

  By the way, the terminal CN1 (1) is the only terminal that can be used to send the fraud detection pulse signal to the outside concentrated terminal board for sending the signal generated by the spinning machine to the outside. Therefore, in order to send out five types of fraud detection pulse signals from one terminal CN1 (1), the fraud detection signal generation unit of the main control board of this embodiment has five types of first to fifth fraud detection pulse signals. Each signal can be identified by changing the pulse interval.

  FIG. 5 is a diagram showing an unauthorized detection opening / closing signal sent to the outside from a pair of terminals CN2 (6), CN2 (8) of the external concentration terminal plate. For example, pattern 1 is a first fraud detection opening / closing signal output based on the first fraud detection pulse signal input to the external concentration terminal plate, and pattern 2 is a second fraud detection pulse signal input to the external concentration terminal plate. The third fraud detection opening / closing signal output based on the third fraud detection opening / closing signal output based on the third fraud detection pulse signal input to the external concentration terminal plate, and the pattern 4 is external concentration. A fourth fraud detection opening / closing signal output based on the fourth fraud detection pulse signal input to the terminal board, and the pattern 5 is output based on the fifth fraud detection pulse signal input to the external concentration terminal board. It is a fraud detection open / close signal. When the high / low signal of the pattern shown in FIG. 5 is high level, the relay contact is in an open state, that is, when the relay coil is not energized, and when low level, the relay contact is closed. That is, a state where the coil of the relay is excited is shown. In consideration of the operation time of the relay used in this embodiment, the low level period of the pattern of FIG. 5, that is, the coil excitation period of the relay is set to 20 ms. The reason why the coil excitation period of the relay is set to 20 ms is that the operation time of the relay is taken into consideration, and the present invention is not limited to this value, and may be shortened according to the operation time of the relay to be used. It can be long. Each pattern in FIG. 5 has the same low level period, but the high level period is 20 ms for pattern 1, 40 ms for pattern 2, 60 ms for pattern 3, 80 ms for pattern 4, and 100 ms for pattern 5. That is, in this embodiment, each signal can be identified by changing a high level period that is a period when the relay is not excited. In this way, by changing the period when the relay is not excited (high level period) instead of the period when the relay is excited (low level period), the period during which the relay is excited is changed. Compared to identifying each signal, the power consumption of the relay can be kept low. Of course, the present invention is not limited to this, and each signal may be identified by changing a low level period, which is a period when the relay is energized.

  In the present embodiment, the fraud detection signal generation unit 111 of the main control board 110 generates and outputs a fraud detection pulse signal so that the relay can be turned on and off as shown in the pattern shown in FIG. . That is, the fraud detection signal generation unit 111 generates and outputs a fraud detection pulse signal having the pattern shown in FIG. The external concentration terminal board converts the fraud detection pulse signal sent from the fraud detection signal generation unit 111 into a fraud detection opening / closing signal corresponding to the fraud detection pulse signal, which is an electrically isolated contact opening / closing signal. Converted and sent to the security signal output board.

  When the rotating game machine sends the fraud detection pulse signal to the external device, the terminal for sending the fraud detection pulse signal to the outside is only one of the terminals CN1 (1). When detected, priorities of fraud detection pulse signals to be sent to the outside are determined in advance and stored in the memory. That is, when a plurality of fraudulent acts are detected at the same time, the main control board 110 of the revolving game machine refers to the priorities of the fraud detection pulse signals stored in the memory and outputs the fraud detection pulse signals with higher priorities. To do. The present invention is not limited to this. For example, when the main control board 110 detects a plurality of frauds at the same time, it refers to the priority order of the fraud detection pulse signals stored in the memory, and the priority order. Only a fraud detection pulse signal having a high value may be output.

  FIG. 6 is a wiring diagram of the security signal output board. The security signal output board 50 is connected to the external concentrated terminal 27 of the swivel-type game machine 1 and has a connector CN3 for input signals having eight terminals, and a set of terminals CN3 from the external concentrated terminal 27 to the connector CN3. (8), CN3 (6) (the common input terminal for crime prevention of the present invention), the fraud detection open / close signal is converted into a fraud detection pulse signal, which is a signal from which the fraud detection open / close signal is converted, and high and low. Is converted to a pulse signal in the reverse state, and the type of fraud is determined based on the pulse state of the pulse signal output from the conversion circuit 510, and a signal corresponding to each fraud is determined for each signal. A determination circuit 520 that outputs from a separate terminal, a drive circuit 530 that converts and outputs a contact open / close signal corresponding to each fraud based on the output signal of the determination circuit 520, and AC24V or DC24 A power supply unit 540 that generates DC5V as an internal power supply from a power supply, a second output connector CN5 (output terminal for crime prevention) for outputting a signal from the drive circuit 530 from a separate terminal for each signal, and an external signal 5 And a first output connector CN4 (game output terminal) for outputting the signal from the external concentrated terminal plate 27 as it is.

  The conversion circuit 510 takes in a plurality of different fraud detection opening / closing signals from a set of terminals CN3 (8), CN3 (6) of the input connector CN3, and the fraud detection opening / closing signals are fraud detection that is a conversion source signal. The pulse signal is converted into a pulse signal in which high and low are reversed, and is output. The conversion circuit 510 includes a comparator IC511 that outputs an ON / OFF signal based on a potential difference between the + input terminal and the − input terminal, four resistors R1 to R4, and two diodes D11 and D12. The + input terminal of the comparator IC511 is connected to the relay common terminal CN3 (6), and is connected to the DC5V power supply via the resistor R2 and the diode D12. The negative input terminal of the comparator IC511 is connected to the relay contact output terminal CN3 (8), is connected to the DC5V power source via the resistor R1 and the diode D11, and is further connected to the ground via the resistor R3. With this connection, if there is no input at both input terminals, 5V is supplied to the + input terminal as a reference voltage, and the − input terminal 2 is obtained by dividing the voltage by the resistance values of the two resistors R2 and R3. .5V is applied. At this time, the output of the comparator IC is turned ON.

  Next, the operation of the conversion circuit 510 will be described. When there is no input at both input terminals of the comparator IC, that is, when the relay RY7 of the external concentration terminal plate is open, a potential difference is generated between the + input terminal and the − input terminal of the comparator IC as described above. The output of the comparator IC is ON (low). On the other hand, when the relay RY7 of the external concentration terminal plate is closed, that is, when the contact of the relay RY7 is short-circuited, the potential between the + input terminal and the −input terminal of the comparator IC is the same and the output of the comparator IC is OFF. (High impedance). At this time, if the resistance values of the resistors R1 to R3 are the same, both the + input terminal and the − input terminal of the comparator IC are 3.3V. Therefore, when the contact of the relay RY7 is in an open state (when the fraud detection pulse signal is high), a potential difference is generated at the input terminal of the comparator IC, and the output is turned on. As a result, the power is supplied to the power source DC5V via the resistor R4. The output signal of the connected conversion circuit is grounded by the comparator IC and becomes 0V (low). On the other hand, when the contact of the relay RY7 is short-circuited (when the fraud detection pulse signal is low), there is no potential difference at the input terminal of the comparator IC, and the output of the comparator IC is turned OFF. As a result, the power is supplied through the resistor R4. The output signal of the conversion circuit connected to DC5V becomes 5V (high).

  As described above, the output signal of the conversion circuit 510 is an excitation pattern of the relay RY7 of the external concentration terminal plate, that is, a fraud detection pulse signal sent out by the rotating game machine and a pulse signal in which high and low are reversed. .

  It is possible to detect the relay contact output of the external signal 5 on the external concentration terminal board by the above configuration and operation. However, it becomes a problem when other relays of the external concentration terminal plate are simultaneously closed. The other relay contacts of the external concentration terminal plate are connected to an external device via a security signal output board, and the relay common of the relays of the external concentration terminal plate is common. Therefore, if the two diodes D11 and D12 are not provided, the voltage supplied from the external device to the relay common wraps around the security signal output board relay circuit via the resistors R1 and R2 of the security signal output board and the DC5V power supply. However, the conversion circuit 510 of the security signal output board according to the present embodiment can prevent different voltages from other external devices from entering the conversion circuit via the relay common by the diode D12. As a result, even when a voltage such as 0 V or 32 V of the external device is applied to the relay common terminal, the conversion circuit 510 is not affected by the different voltages applied to the relay common terminal from these external devices, and is normal. Can be performed. Furthermore, when the relay RY7 of the external concentration terminal plate is in a closed state, different voltages such as 0V and 32V of the external device are applied to the relay common, and these different voltages are connected to the DC5V of the conversion circuit via the terminal CN3 (8). Even if it tries to sneak into the power source, the sneak current of these different power sources can be prevented by the diode D11.

  The determination circuit 520 includes a microcomputer 525 having a CPU 521, a ROM 522, a RAM 523, and the like, and a clock generation circuit 526 for supplying a clock to the microcomputer 525. The input terminal IN of this determination circuit is connected to the output of the conversion circuit 510, and the output terminals OUT1 to OUT5 are connected to the drive circuit 530. The CPU 521 executes a program stored in the ROM 522, so that the pulse signal which is the output signal of the conversion circuit and is input to the input terminal IN is out of the five fraud detection pulse signals sent out by the revolving game machine. By determining which fraud detection pulse signal corresponds to the signal and outputting ON (high) to the corresponding output terminal OUT, a signal corresponding to the fraudulent action is provided for each signal as a separate output terminal OUT1. 5 is output. The RAM 523 is a working memory that temporarily stores data.

  Judgment circuit 520 determines the fraud detection pulse corresponding to any fraudulent action from the contents of the pulse signal sent from the conversion circuit (the fraud detection pulse signal sent by the revolving game machine and the pulse signal in which high and low are reversed). It is determined whether the signal is a signal, and a signal indicating the result is output from the output terminals OUT1 to OUT5. When the pulse signal input to the input terminal IN is a signal corresponding to the first fraud detection pulse signal, the output terminal OUT1 is turned ON (high), and the other output terminals OUT2 to OUT5 are turned OFF (low). When the pulse signal input to the input terminal IN is a signal corresponding to the second fraud detection pulse signal, the output terminal OUT2 is turned ON (high), and the other output terminals OUT1, 3 to 5 are turned OFF (low). When the pulse signal input to the input terminal IN is a signal corresponding to the third fraud detection pulse signal, the output terminal OUT3 is turned ON (high), and the other output terminals OUT1, 2, 4, 5 are turned OFF (low). To do. When the pulse signal input to the input terminal IN is a signal corresponding to the fourth fraud detection pulse signal, the output terminal OUT4 is turned ON (high), and the other output terminals OUT1 to OUT3, 5 are turned OFF (low). When the pulse signal input to the input terminal is a signal corresponding to the fifth fraud detection pulse signal, the output terminal OUT5 is turned ON (high), and the other output terminals OUT1 to OUT4 are turned OFF (low).

  FIG. 7 is a flowchart for explaining the operation of the determination circuit. In step S1, all the output terminals OUT1 to OUT5 are turned off (low). Next, a process for detecting the first pulse of the pulse signal output from the conversion circuit is performed. In step S2, it waits for the state of the pulse signal applied to the input terminal IN to become high. When the contact of the relay RY7 of the external concentration terminal is closed and the state of the pulse signal applied to the input terminal IN becomes high, the process proceeds to step S3 and the built-in timer 1 is started. In step S4, it is monitored whether or not the input terminal IN has changed from a high state to a low state. If not changed, the process proceeds to step S5 and it is confirmed that the value of timer 1 does not exceed 20 ms + 10%. At this time, if the value of the timer 1 exceeds 20 ms + 10%, the state is abnormal and the operation is not specified, so the routine proceeds to step S6 and the timer 1 is stopped. Note that the value of + 10% takes into account the error in the operation time of the relay RY. In step S7, after waiting for the input terminal IN to change from the high state to the low state, the process returns to step S1, and processing is newly performed from the beginning. On the other hand, if it is determined in step S5 that the value of timer 1 does not exceed 20 ms + 10%, the process returns to step S4 to monitor whether the input terminal IN has changed from the high state to the low state.

  When it is confirmed in step S4 that the input terminal IN has changed from the high state to the low state, the relay RY7 of the external concentration terminal is turned off, and the state of the pulse signal applied to the input terminal IN is in the low state. In step S8, the timer 1 is stopped. In step S9, it is confirmed whether or not the value of the stopped timer 1 is within a range of 20 ms ± 10%. If it is within this range, the first pulse of the pulse signal output from the conversion circuit has been detected. Next, the second pulse of the pulse signal is detected. On the other hand, if it is out of this range, the operation is not specified, so the process returns to step S1 and a new process is performed from the beginning. Note that ± 10% is also considered in consideration of an error in the operation time of the relay RY. Therefore, the present invention is not limited to a numerical value of 20 ms ± 10%, and can be shorter when the operation time of the relay is short. The same applies hereinafter.

  In step S10, timer 2 is started. In step S11, it is monitored that the state of the pulse signal applied to the input terminal IN changes from the low state to the high state. If there is no change, the process proceeds to step S12 to confirm that the value of timer 1 does not exceed 100 ms + 10%. If the value of the timer 1 exceeds 100 ms + 10%, the operation is not specified, so the timer 2 is stopped and the process returns to step S1, and processing is newly performed from the beginning. On the other hand, if 100 ms + 10% is not exceeded, the process returns to step S11 to monitor the change of the state of the pulse signal applied to the input terminal IN from the low state to the high state. When the contact of the relay RY7 of the external concentration terminal is closed and the state of the pulse signal applied to the input terminal IN becomes high, the process proceeds to step S14 to stop the timer 2 and start the timer 1 in step S15. To do. In step S16, it is determined whether or not the value of timer 2 is within a range of 20 ms ± 10%. If it is within this range, since the second pulse has been sent within the range of 20 ms ± 10%, it is determined that this pulse signal is a signal corresponding to the first fraud detection pulse signal, and the process goes to step S17. Then, the output terminal OUT1 is turned on (high), the other output terminals are turned off (low), the process returns to step S4, and the above-described processing is repeated. On the other hand, if it is determined in step S16 that the value of timer 2 is outside the range of 20 ms ± 10%, the process proceeds to step S18.

  In step S18, it is determined whether or not the value of timer 2 is within a range of 40 ms ± 10%. If it is within this range, since the second pulse has been sent within the range of 40 ms ± 10%, it is determined that this pulse signal is a signal corresponding to the second fraud detection pulse signal, and the process goes to step S19. Then, the output terminal OUT2 is turned on (high), the other output terminals are turned off (low), the process returns to step S4, and the above-described processing for detecting the first pulse is repeated. On the other hand, if it is determined in step S18 that the value of timer 2 is outside the range of 40 ms ± 10%, the process proceeds to step S20.

  In step S20, it is determined whether or not the value of timer 2 is within a range of 60 ms ± 10%. If it is within this range, since the second pulse has been sent within the range of 60 ms ± 10%, it is determined that this pulse signal is a signal corresponding to the third fraud detection pulse signal, and the process goes to step S21. Then, the output terminal OUT3 is turned ON (high), the other output terminals are turned OFF (low), the process returns to step S4, and the above-described processing is repeated. On the other hand, when it is determined in step S20 that the value of timer 2 is outside the range of 60 ms ± 10%, the process proceeds to step S22.

  In step S22, it is determined whether or not the value of timer 2 is within a range of 80 ms ± 10%. If it is within this range, the second pulse has been sent within the range of 80 ms ± 10%, so it is determined that this pulse signal is a signal corresponding to the fourth fraud detection pulse signal, and the process goes to step S23. Then, the output terminal OUT4 is turned on (high), the other output terminals are turned off (low), the process returns to step S4, and the above-described processing is repeated. On the other hand, when it is determined in step S22 that the value of timer 2 is out of the range of 80 ms ± 10%, the process proceeds to step S24.

  In step S24, it is determined whether or not the value of timer 2 is within a range of 100 ms ± 10%. If it is within this range, since the second pulse has been sent within the range of 100 ms ± 10%, it is determined that this pulse signal is a signal corresponding to the fifth fraud detection pulse signal, and the process goes to step S25. Then, the output terminal OUT5 is turned on (high), the other output terminals are turned off (low), the process returns to step S4, and the above-described processing is repeated. On the other hand, if it is determined in step S24 that the value of timer 2 is out of the range of 100 ms ± 10%, the process of detecting the second pulse is an out-of-specific operation, so the process proceeds to step S26 and all outputs are performed. The terminals OUT1 to OUT5 are turned OFF (low), the process returns to step S4, and the above-described processing is repeated.

  The drive circuit 530 drives the photoMOS relay based on the ON (high) or OFF (low) output signal of the determination circuit 520, and the contact open / close signal of the contact electrically isolated from the determination circuit 520 (the crime prevention of the present invention). This is a circuit that converts the signal into an open / close signal and outputs it, and has five individual drive circuits 531 to 535. Each of the drive circuits 531 to 535 includes a transistor Q that becomes conductive when a high signal is sent from the output terminal OUT of the determination circuit, and a photoMOS relay PM that operates when the transistor Q becomes conductive. Is provided. The contact points of the photo-threshing PMs of the drive circuits 531 to 535 are open when the output terminal of the determination circuit is low, and are closed when the output terminal of the determination circuit is high. The open / close signals of the contacts of the drive circuits 531 to 535 are transmitted to the external device 80 via the connectors CN51 to 55 of the second output connector CN5 so that the signals are independent of the contacts of the other drive circuits. Is output. That is, the second output connector CN5 includes five connectors CN51 to 55 each having a set of two terminals. In this way, by converting the signal output from the determination circuit into an open / close signal of a contact that is electrically insulated from the signal, the external device that receives the open / close signal receives the open / close signal. Therefore, it is possible to prevent the electric trouble caused by the failure and to reliably transmit a signal notifying that an illegal act has been detected to the external device.

  In the crime prevention signal output board of this embodiment, a 470 Ω resistor and a 0.1 μF capacitor connected in series are connected to the contact of each relay RY in order to prevent a surge of the contact of the relay RY of the external concentration terminal board. Connected in parallel.

  Next, the operation of this embodiment will be described. The main control board of the revolving gaming machine 1 generates and generates five fraud detection pulse signals (first to fifth) that can identify each fraud when detecting the fraud by the sensors S1 to S5. Each fraud detection pulse signal is sent to the terminal CN1 (1) of the external concentration terminal board. The external concentration terminal board converts the high / low signal of the fraud detection pulse signal sent from the main control board into an open / close signal (fault detection open / close signal) by the relay RY, and the converted fraud detection open / close signal is integrated. The signal is sent to the security signal output board 50 via the pair of terminals CN2 (6) and CN2 (8).

  The conversion circuit 510 of the crime prevention signal output board 50 is configured so that the fraud detection opening / closing signal sent from the rotating game machine is in a state where the fraud detection pulse signal, which is the conversion source signal of the fraud detection opening / closing signal, is high and low. Converted to a pulse signal and output. The determination circuit determines which of the first to fifth fraud detection pulse signals corresponds to the pulse signal converted by the conversion circuit. For example, the pulse signal corresponding to the first fraud detection pulse signal If it is determined, the output terminal OUT1 is set high and the other output terminals are set low. When any one of the output terminals of the determination circuit becomes high, the contact of the photoMOS relay PM of the drive circuit connected to the output terminal is closed, and the open / closed state (open / close signal) of this contact is the second output connector CN5. To the external device 80.

  On the other hand, the external signals 1 to 4 other than the medal insertion signal, the medal payout signal, and the fraud detection pulse signal are sent as they are to the external device via the first output connector CN4. For example, during a game, when a symbol “7-7-7” appears on the active line, it becomes a medium continuous action device (large bonus) related to the first type special character, and a medal is discharged as a prize medal. When the number reaches the predetermined number (for example, 450), the game in the accessory continuous operation apparatus related to the first type special accessory is ended. When entering the accessory continuous operation apparatus related to the first type special accessory, the main control board 110 sends an ON signal to the terminal CN1 (4) for the external signal 2. This signal is sent to the output terminal CN2 (4) via the individual interface circuit IN4 (relay RY4 etc.), and further sent to the external device as it is via the security signal output board 50. When the game in the accessory continuous operation apparatus relating to the first kind special accessory is completed, the main control board 110 sets the ON signal sent to the terminal CN1 (4) for the external signal 2 as the OFF signal. The other external signals 1, 3, 4 and the medal insertion signal and medal payout signal are also sent to the external device as they are through the security signal output board. Note that the terminal CN4 (8) of the first output connector CN4 is an empty terminal that is not connected to any line.

  According to the above-described embodiment, the spinning-reel-type gaming machine has five signals that inform the outside that fraud has been detected, and the existing external concentration without providing a new terminal on the existing external concentration terminal board. A signal indicating that these five frauds have been detected can be sent to an external device from one terminal CN1 (1) and a pair of terminals CN2 (6) and CN2 (8). Accordingly, it is possible to collectively manage a plurality of types of fraudulent acts performed by a large number of existing revolving game machines provided in the game hall using an existing external device.

  In addition, according to the above-described embodiment, the output signal corresponding to the fraud detection pulse signal transmitted from the security signal output board to the external device is output from a separate output terminal for each signal, and no common common is provided. Therefore, each output signal circuit is an independent circuit and does not adversely affect other output signal circuits.

  In addition, the above-described crime prevention signal output board of the present embodiment sends signals other than the external signal 5 (injustice detection pulse signal) out of the signals sent out by the rotating game machine to the external device as they are, The present invention can be provided between an existing spinning machine and an external device without major modifications or changes to the existing spinning machine or external device.

  Next, another example of the fraud detection pulse signal, which is a modification of the present embodiment, will be described. FIG. 8 is a diagram showing another example of the fraud detection opening / closing signal sent to the outside from a pair of terminals CN1 (6), CN2 (8) of the external concentration terminal plate. For example, pattern 1 is a first fraud detection opening / closing signal output based on the first fraud detection pulse signal input to the external concentration terminal plate, and pattern 2 is a second fraud detection pulse signal input to the external concentration terminal plate. The third fraud detection opening / closing signal output based on the third fraud detection opening / closing signal output based on the third fraud detection pulse signal input to the external concentration terminal plate, and the pattern 4 is external concentration. A fourth fraud detection opening / closing signal output based on the fourth fraud detection pulse signal input to the terminal board, and the pattern 5 is output based on the fifth fraud detection pulse signal input to the external concentration terminal board. It is a fraud detection open / close signal. The high / low number of the pattern shown in FIG. 8 is when the relay contact is open, that is, when the relay coil is not excited, when it is high, and when the relay contact is closed, the relay contact is closed. That is, a state where the coil of the relay is excited is shown.

  The fraud detection opening / closing signal shown in FIG. 8 has a header portion and a signal pattern portion (identification signal pattern portion of the present invention) to identify five fraud detection opening / closing signals. The header portion indicates that the subsequently transmitted signal is data, and the signal pattern portion is a data body to be transmitted. The width of each low level period of the signal pattern portion is 20 ms, and the width of the low level period of the header portion is 40 ms which is twice the width of the low level period of the signal pattern portion. Thereby, the signal of a header part and the signal of a signal pattern part can be distinguished. Note that the width of each low level period of the signal pattern portion is set to 20 ms in consideration of the operation time of the relay RY used in the present embodiment. Each pattern differs in the state of the signal pattern portion sent following the header portion. In the signal pattern of pattern 1, the first low level signal is sent following the header portion. In the signal pattern of pattern 2, the second low level signal is sent following the header portion. In the signal pattern of pattern 3, the first and second low level signals are sent following the header portion. In the signal pattern of pattern 4, the third low level is sent following the header portion. In the signal pattern of pattern 5, the first and third low level signals are sent following the header portion.

  The fraud detection signal generation unit 111 of the main control board generates and outputs a fraud detection pulse signal so that the relay RY7 can be turned on and off as in the pattern shown in FIG. That is, the fraud detection signal generation unit 111 generates and outputs a fraud detection pulse signal having the pattern shown in FIG.

  The fraud signal opening / closing signal having the pattern shown in FIG. 8 is also converted into a pulse signal in which the fraud detection pulse signal of the conversion source and high and low are reversed by the conversion circuit of the security signal output board and supplied to the determination circuit. The operation of the conversion circuit in this case is the same as that for converting the fraud detection opening / closing signal having the pattern shown in FIG.

  Next, the pulse signal converted by the conversion circuit (the fraud detection pulse signal and the signal in which high and low are reversed) is received, and the received pulse signal is one of the five fraud detection pulse signals. The operation of the determination circuit for determining whether or not it corresponds to the above will be described.

  9 to 11 are flowcharts for explaining the operation of the determination circuit when the fraud detection opening / closing signal is sent in the pattern shown in FIG. 8, FIG. 9 is an overall flowchart, and FIG. 10 is the step of FIG. FIG. 11 is a detailed flowchart from the circle A to the circle B in FIG.

  FIG. 12 is a diagram for explaining a pulse signal sent to the input terminal IN of the determination circuit. In the following, among the pulse signals sent to the input IN of the determination circuit, as shown in FIG. 12, the first pulse of the signal pattern part sent following the header part is also referred to as first data. The second pulse sent after the second data, the third pulse sent after the second data, the third data, and the fourth pulse sent after the third data. The pulse is also referred to as fourth data.

  The interrupt process in step S33 in FIG. 9 is executed every 1 ms. This interrupt processing is for detecting the header portion every 1 ms. When the trailing edge of the header portion is detected, the pulse of the signal pattern portion is detected with reference to the trailing edge of the header portion. In the present embodiment, the determination circuit includes two flags, a header detection flag and a header detection start flag, as flags for the header portion. The header detection flag is a flag that is turned on when the header portion is detected. The header detection start flag is a flag that is turned on when detection of the header portion is started.

  In step S31, the header detection flag is turned off, and in step S32, the header detection start flag is turned off. In step S33, interrupt processing is performed. By this interrupt processing, a header portion having a width of 40 ms is detected from the pulse signal input to the input terminal of the determination circuit.

  In step S65 of the interrupt process shown in FIG. 10, the state of the header detection start flag is confirmed. At this time, since the header detection start flag is off, the process proceeds to step S73 to determine whether the input terminal IN of the determination circuit is high or low. If the input terminal of the determination circuit is not high, this interrupt process is terminated, and the process proceeds to the main flow shown in FIG. On the other hand, when high is input to the input terminal IN of the determination circuit, this is detected in step S73, the process proceeds to step S74, the header detection start flag is set on, and a counter for measuring time is set. The value is set to 0, this interrupt process is terminated, and the process proceeds to the main flow. In the next interrupt process after the elapse of 1 ms, since the header detection start flag is on, the process proceeds from step S65 to step S66. In step S66, it is determined whether or not the value of the counter exceeds 40 + 10% (that is, 40 ms + 10%). Since the value of the counter is now 0, the process proceeds to step S67 to increment the counter value and add 1. If the value of the counter exceeds 40 + 10%, the operation is not specified. Therefore, without incrementing the value of the counter, the process proceeds to step S68 to monitor whether the input terminal IN of the determination circuit becomes low. If the input terminal IN of the determination circuit is not low, the interrupt process is terminated and the process returns to the main flow shown in FIG. This interrupt process is executed every 1 ms, and the counter is incremented until the input terminal of the decision circuit goes low. If the counter value exceeds 40 ms + 10%, the process proceeds to step S68 to monitor whether the input terminal of the determination circuit becomes low.

  When the interrupt process is executed after several tens of milliseconds have elapsed, if the input terminal IN of the determination circuit is low, the process proceeds from step S68 to step S69. In step S69, it is determined whether or not the value of the counter is within a range of 40 ms ± 10%. If the value of the counter is within the range of 40 ms ± 10%, the header detection flag indicating that the header has been detected is set on in step S70, the header detection start flag is turned off, and this interrupt processing is terminated. Return to the main flow. In this state, the determination circuit detects the header portion, and executes a main flow process to be described later. On the other hand, if it is determined in step S69 that the counter value is not within the range of 40 ms ± 10%, the operation is not specified. Therefore, the process proceeds to step S71, where the header detection flag is originally off. The header detection flag is turned off, the header detection start flag is turned off in step S72, and the process returns to the main flow in preparation for detection of the next header portion.

  Now, assuming that a 20 ms wide signal is input to the input terminal IN of the determination circuit, even if a low level after 20 ms is detected in step S68, the process proceeds from step S69 to step S71. The header detection flag is turned off and the header detection flag is never turned on. That is, both the header of 40 ms width and the pulse of 20 ms width are input to the input terminal IN of the determination circuit even during normal operation. In this interrupt processing, the header section of 40 ms ± 10% width is input to the input terminal IN. Only when is input, the header detection flag is set to ON and it is recognized that the header portion has been detected. The 40 ms ± 10% is considered in consideration of the error of the operation time of the relay of the external concentration terminal. By the interrupt processing shown in FIG. 10 described above, the header portion of the signal sent to the input terminal IN of the determination circuit can be detected.

  Next, in the processing after step S34 of the main flow in FIG. 9, it is determined which of the five fraud detection pulse signals the pulse signal corresponding to the fraud detection pulse signal is output from the conversion circuit. . In step S34, all output terminals OUT1 to OUT5 of the determination circuit are turned OFF (low) as initialization processing. In step S35, the timer 2 which is a timer for initializing the output terminal OUT of the determination circuit is started when the header portion is not detected within a certain period, which is built in the determination circuit. That is, if it is determined in step S36 that the header detection flag is not detected, the process proceeds to step S37 to determine whether the value of timer 2 exceeds 500 ms. If it is greater than 500 ms, the timer 2 is stopped in step S38, the process returns to step S34, and the output terminal OUT of the determination circuit is initialized. When the value of the timer 2 is 500 ms or less, the process returns to step S36 and the detection of the header part is monitored. That is, the process of initializing the output terminal OUT of the determination circuit is performed every 500 ms by the process from step S35 to step S38 to prepare for the next pulse signal detection process.

  When the header part is detected in step S36, the process goes to step S39 to stop the timer 2, and the process goes to step S40 to turn off the header detection flag and detect the next header part in the interrupt process of step S33. In addition, the process proceeds to step S41 and subsequent steps, and a determination process of the pulse state of the signal pattern portion which is the data portion is performed. In the present embodiment, in order to identify the five types of fraud detection pulse signals, the five types of fraud detection pulse signals are also identified in the processing after step S31.

  The fraud detection opening / closing signal shown in FIG. 8 sent to the crime prevention signal output board via the external concentration terminal board is converted into a pulse signal in which the fraud detection pulse signal of the conversion source and the high and low are reversed by the conversion circuit 510. . When the fraud detection opening / closing signal of pattern 1 shown in FIG. 8 is sent, the first data is sent as the pulse signal output from the conversion circuit following the header portion shown in FIG. When the fraud detection opening / closing signal of pattern 2 shown in FIG. 8 is sent, the pulse data output from the conversion circuit is sent the second data following the header portion. When the fraud detection opening / closing signal of pattern 3 shown in FIG. 8 is sent, the pulse data output from the conversion circuit is sent with the first data and the second data following the header portion. When the fraud detection opening / closing signal of pattern 4 shown in FIG. 8 is sent, the third data is sent as the pulse signal output from the conversion circuit following the header portion. When the fraud detection opening / closing signal of pattern 5 shown in FIG. 8 is sent, the pulse data output from the conversion circuit is sent with the first data and the third data following the header portion.

  Next, processing for determining the pulse state of the signal pattern portion will be described. First, an outline of processing from the circle A to the circle B will be described with reference to FIG. In steps S41 and S42 in FIG. 9, the first data is determined. In step S41, monitoring of the first data is started and an error is detected. If there is an error, the process returns to step S34, and the output terminal OUT of the determination circuit is initialized because the operation is not specified. In step S42, a value (determination value described later) is acquired and recorded based on the presence or absence of the first data.

  In steps S43 and S44, the second data is determined. In step S43, monitoring of the second data is started and an error is detected. If there is an error, the process returns to step S34, and the output terminal OUT of the determination circuit is initialized because the operation is not specified. In step S44, based on the presence or absence of the second data, a value (a determination value described later) is acquired, added to the recording data, and recorded.

  In steps S45 and S46, the third data is determined. In step S45, monitoring of the third data is started and an error is detected. If there is an error, the process returns to step S34, and the output terminal OUT of the determination circuit is initialized because the operation is not specified. In step S46, based on the presence / absence of the third data, a value (a determination value described later) is acquired, added to the recording data, and recorded.

  In steps S47 and S48, the fourth data is determined. In step S47, monitoring of the fourth data is started and an error is detected. If there is an error, the process returns to step S34, and the output terminal OUT of the determination circuit is initialized because the operation is not specified. In step S48, based on the presence or absence of the fourth data, a value (determination value described later) is acquired, added to the recording data, and recorded. By the processes from step S42 to step S48, determination values 0 to 15 described later are obtained.

  Next, detailed processing from the circle A to the circle B will be described with reference to FIG. In step S81, the timer 2 built in the determination circuit is started. In the following processing, the timer 2 is used for detecting a pulse having a width of 20 ms. Further, the processing in step S81 is processing after the header portion is detected in step S36. That is, the pulse is detected after the header portion is detected. In step S82, it is determined whether or not the timer 2 has timed 10 ms in order to time the center of the off period between the header portion shown in FIG. 12 and the next first data. If the timer 2 is measuring 10 ms, after the timer 2 is stopped in step S83, it is determined in step S84 whether or not the input terminal IN of the determination circuit is low. At this time, if the input of the determination circuit is high, the operation is not specified, so the process returns to step S34 to initialize the output of the determination circuit. In this embodiment, 10 ms after detecting the header portion, the input terminal of the determination circuit does not go high. Therefore, it is determined that a malfunction has occurred, and the output of the determination circuit is initialized. Thereby, the header part detected this time is processed as invalid data as data.

  On the other hand, if the input terminal IN of the determination circuit is low, in order to determine the presence or absence of the first data, the process proceeds to step S85, the timer 2 is started, and it is determined whether the timer 2 has timed 20 ms. (Step S86). If the timer is measuring 20 ms, the process proceeds to step S87 to stop timer 2, and in step S88, it is determined whether or not the input terminal IN of the determination circuit is high. If the input terminal IN is not high, 0 is stored as a determination value (step S90), and if it is high, 1 is stored as a determination value (step S89).

  In step S91, the timer 2 is restarted to confirm the intermediate low state between the first data and the second data shown in FIG. In step S92, in order to detect the center of the low state, it is determined whether or not the timer 2 has counted 20 ms. If the timer 2 is measuring 20 ms, after the timer 2 is stopped in step S93, it is determined in step S94 whether or not the input IN of the determination circuit is low. At this time, if the input of the determination circuit is high, the operation is not specified, so the process returns to step S34 to initialize the output of the determination circuit.

  On the other hand, if the input terminal IN of the determination circuit is low, in order to determine the presence or absence of the second data, the process proceeds to step S95 to start the timer 2, and whether or not the timer 2 has timed 20 ms in step S96. Determine whether. If the timer is measuring 20 ms, the process proceeds to step S97 to stop the timer 2, and in step S98, it is determined whether or not the input terminal IN of the determination circuit is high. If the input terminal IN is not high, the process proceeds to step S100 without adding to the determination value, and if it is high, 2 is added to the determination value and stored (step S99). Therefore, at this stage, the determination value is 0, 1, 2, or 3.

  In step S100, the timer 2 is restarted to confirm the intermediate low state between the second data and the third data shown in FIG. In step S101, in order to detect the center of this low state, it is determined whether or not the timer 2 has counted 20 ms. If the timer 2 is measuring 20 ms, after the timer 2 is stopped in step S102, it is determined in step S103 whether or not the input terminal IN of the determination circuit is low. At this time, if the input terminal IN of the determination circuit is high, the operation is not specified, so the process returns to step S34 to initialize the output of the determination circuit.

  On the other hand, if the input terminal IN of the determination circuit is low, the process proceeds to step S104 to start the timer 2 in order to determine the presence or absence of the third data, and whether or not the timer 2 has counted 20 ms in step S105. Judging. If the timer is measuring 20 ms, the process proceeds to step S106 to stop the timer 2, and in step S107, it is determined whether or not the input terminal IN of the determination circuit is high. If the input IN is not high, the process proceeds to step S109 without adding to the determination value. If the input IN is high, 4 is added to the determination value and stored (step S108). Therefore, at this stage, the determination value is any one of 0 to 7.

  In step S109, the timer 2 is restarted to confirm the intermediate low state between the third data and the fourth data shown in FIG. In step S110, in order to detect the center of this low state, it is determined whether or not the timer 2 has counted 20 ms. If the timer 2 is measuring 20 ms, after the timer 2 is stopped in step S111, it is determined whether or not the input terminal IN of the determination circuit is low in step S112. At this time, if the input terminal IN of the determination circuit is high, the operation is not specified, so the process returns to step S34 to initialize the output of the determination circuit.

  On the other hand, if the input of the determination circuit is low, in order to determine the presence or absence of the fourth data, the process proceeds to step S113 to start timer 2, and in step S114, it is determined whether timer 2 has counted 20 ms. To do. If the timer is measuring 20 ms, the process proceeds to step S115 to stop timer 2, and in step S116, it is determined whether or not the input terminal IN of the determination circuit is high. If the input terminal IN is not high, the process proceeds to step S51 without adding it to the determination value. If it is high, 8 is added to the determination value and stored (step S117), and the process proceeds to step S51 to determine the determination value. Move on to processing. At this stage, the determination value is any value from 0 to 15.

  Next, based on the determination value determined in the process of FIG. 11 described above, a process of determining which fraudulent action the current pulse signal corresponds to and outputting a signal from the corresponding output terminal will be described. To do. In step S51, it is determined whether or not the determination value is 0. If not, it is determined whether or not the determination value exceeds 5 in step S52. If the determination value is 0 in step S51, or if the determination value is greater than 5 in the determination in step S52, the process proceeds to step S53, and all the output terminals OUT of the determination circuit are set to low. That is, when the determination value is other than 1 to 5, all the output terminals of the determination circuit are set to low and initialized. When it is determined in step S52 that the determination value does not exceed 5, the process proceeds to step S54.

  In step S54, it is determined whether or not the determination value is 1. If the determination value is 1, the process proceeds to step S55, and since the pulse signal at this time corresponds to the first fraud detection pulse signal, the output terminal OUT1 of the determination circuit is set to high, and the other output terminals Set OUT2-5 to low. When the determination value is not 1, the process proceeds to step S56. In step S56, it is determined whether or not the determination value is 2. If the determination value is 2, the process proceeds to step S57, and since the pulse signal at this time corresponds to the second fraud detection pulse signal, the output terminal OUT2 of the determination circuit is set high and the other output terminals Set OUT1, 3-5 to low. When the determination value is not 2, the process proceeds to step S58.

  In step S58, it is determined whether or not the determination value is 3. If the determination value is 3, the process proceeds to step S59, and the pulse signal at this time corresponds to the third fraud detection pulse signal. Set OUT1, 2, 4, 5 to low. When the determination value is not 3, the process proceeds to step S60. In step S60, it is determined whether or not the determination value is 4. If the determination value is 4, the process proceeds to step S61, and the pulse signal at this time corresponds to the fourth fraud detection pulse signal. Set OUT1-3,5 to low. When the determination value is not 4, the process proceeds to step S62.

  As a result of the processing of steps S51 to S61 described above, the determination value is 1 to 5 and is not any of 1 to 4. Therefore, the determination circuit knows that the determination value in this case is 5. Therefore, in step S62, since the pulse signal at this time corresponds to the fifth fraud detection pulse signal, the output terminal OUT5 of the determination circuit is set to high, and the other output terminals OUT1 to OUT4 are set to low. Returning to the following, the processing of the next pulse signal is performed by performing the processing from step S35 to step S62 described above.

  The fraud detection opening / closing signal shown in FIG. 5 increases in length as the number of fraud detection opening / closing signals increases. On the other hand, in the case of the fraud detection opening / closing signal shown in FIG. 8, up to 16 fraud detection opening / closing signals can be transmitted without changing the length of the entire signal. That is, this modification is suitable for the case where a signal in which many illegal acts are detected is sent to the outside.

However, a plurality of illegal common input terminals and a plurality of illegal common output terminals may be provided.

  In the above embodiment, the case where the security signal output board sends the output signal of the determination circuit to the external device via the drive circuit has been described. However, the security signal output board does not include the drive circuit, and the determination circuit The output signal may be sent directly to an external device.

  In the above embodiment, the case where a sensor is used as the detection unit has been described. However, the present invention is not limited to this. For example, in order to detect that the power is turned on, the sensor is not a power supply sensor. Alternatively, a timer or the like that is turned on only for a certain time after the power is turned on may be used. Further, since it is the main control board that issues the hopper motor drive signal, a function equivalent to that of the hopper motor sensor may be realized in software on the main control board instead of the hopper motor sensor.
