For example, a fraudulent act is performed by cutting a cable and connecting the cut portion with an unauthorized cable or substrate interposed therebetween. In addition, by connecting an illegal cable or board to the cut portion, there is a risk of adversely affecting the board connected to the cable and even other boards.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the gaming machine which makes it difficult to do fraud.

In order to achieve such an object, the present invention has the following configuration .

  The “game state detection / determination means” described in the present specification includes, for example, identification information (for example, a special symbol variation display device) on the identification information variation display device (for example, based on a winning game ball) For example, based on the first winning detection means (for example, the first type start port switch) that triggers the variation display of special symbols and the like, or based on the winning of the game ball, for example, the normal identification information variation display device (for example, normal A second winning detection means for triggering a variable display of normal identification information (for example, a symbol such as a normal symbol) on a symbol variation display device, etc., and a third winning detection means for detecting a ball won in the normal winning opening ( For example, there are various winning (winning) detection devices and parts such as a normal winning switch) and fourth winning detection means (for example, a count switch) for detecting a ball that has won a big winning opening. The “operation / control unit” described in the present specification includes, for example, a relay board that receives a signal from the gaming state detection / determination unit and relays it to another control unit, or a gaming state detection / determination. Examples include various control boards and devices such as a main control board and a payout control board that perform predetermined control based on signals from the means.

That is, the invention according to claim 1 is a gaming machine comprising gaming state detection / determination means for detecting or determining a gaming state and control means for controlling the gaming machine.
An optical transmission means for connecting the gaming state detection / determination means and the control means;
The optical transmission means includes an optical cable for transmitting and receiving an optical signal between the gaming state detection / determination means and the control means, and connectors connected to both ends of the optical cable,

The optical transmission means further includes a transmitting unit for converting an electrical signal from the gaming state detection / determination means into an optical signal in a connector connected to the gaming state detection / determination means among the two connectors.
The main control board includes a receiving unit that converts an optical signal transmitted through the optical cable into an electrical signal,
Furthermore, it comprises fraud prevention means for preventing fraudulent acts related to the optical transmission means,
The fraud prevention means is characterized in that at least the connector on the main control board side is destroyed so that it cannot be reconnected to the main control board when it is removed from the main control board.

[Operation / Effect] According to the invention described in claim 1, the optical transmission means includes an optical cable for transmitting and receiving an optical signal between the gaming state detection / determination means and the control means, and a connector connected to the optical cable. The control means is a main control board that controls the gaming machine in an integrated manner. By connecting each connector to the game state detection / determination means and the main control board, the game state detection / determination means and the control means are connected to each other. They are connected by optical transmission means. In addition, by adopting a configuration in which at least the connector on the main control board side is broken so that it cannot be reconnected to the main control board when it is removed from the main control board, a highly versatile connector (for example, a commercially available connector) In comparison, it becomes difficult to remove and connect an unauthorized optical cable or the like, thereby fulfilling the function of fraud prevention means. The fraud prevention means may be adopted not only for the connector on the main control board side described above but also for the connector on the gaming state detection / determination means side.

According to the invention described in claim 2 , in the gaming machine according to claim 1 ,

If it is difficult to operate, once convert the optical signal to an electrical signal (O / E conversion), manipulate the converted electrical signal, then convert the manipulated electrical signal to an optical signal again (E / O conversion) must be performed. In other words, in order to illegally generate a big hit by manipulating an optical signal, the optical transmission means is disconnected, and an illegal electric transmission means or an electrical connection portion is connected to the cut portion, and further electric transmission is performed. It is necessary to connect the conversion unit for O / E conversion and E / O conversion to the input / output terminals of the means or the electrical connection unit, which is troublesome.

  In addition, it is illegal to connect via an unauthorized electric transmission means (cable) or an electrical connection part (for example, a board) so as to change from a normal state unfavorable to the player to an advantageous special gaming state (for example, a big hit state). Therefore, the target connected to the optical transmission means other than the control means is limited to the gaming state detection / determination means for detecting or determining the gaming state. Therefore, it is not necessary to connect other detection means or means to be electrically connected to the control means (for example, sound generation means [for example, a speaker], illumination means (for example, a lamp), etc.) with an optical transmission means.

  In this way, it is difficult to disconnect the optical transmission unit and connect the optical transmission unit with the illegal optical transmission unit at the cut position, so that it is possible to make it difficult to perform an illegal act.

[Operation and Effect] According to the invention described in claim 6 , the gaming state detection / determination means detects or determines the gaming state. That is, the gaming state detection means detects the gaming state, and the gaming state determination means determines the gaming state. The operation / control unit performs a predetermined operation or control based on a signal from the gaming state detection / determination unit. That is, the operation means performs a predetermined operation based on a signal from the gaming state detection / determination means, and the control means performs predetermined control based on a signal from the gaming state detection / determination means. The optical transmission means optically connects the gaming state detection / determination means and the operation / control means. The transmission unit of the optical transmission unit transmits a signal from the gaming state detection / determination unit via the optical cable. The receiving unit of the optical transmission unit receives a signal transmitted from the transmitting unit via the optical cable. The abnormality detection unit of the optical transmission means detects a communication abnormality between the transmission unit and the reception unit via the optical cable. In the case of a communication abnormality in the abnormality detection unit, the reception unit sets the output as an output that does not operate the operation / control unit. In other words, the abnormality detection unit detects a communication abnormality when the optical cable is disconnected or the optical cable is repeatedly disconnected and connected, and the reception unit receives the communication unit in the case of a communication abnormality at the abnormality detection unit. The output is an output that does not operate the operation / control means. Therefore, even if the optical cable is cut or the optical cable is cut and connected repeatedly, the output of the receiving unit can be an output that does not operate the operation / control means. It is possible to prevent the control means from operating, and it is possible to prevent illegal acts caused by the optical cable being cut or the optical cable being repeatedly cut and connected.

Further, according to the invention of claim 7, the gaming machine according to any one of claims 3 to 6,

That is, the operation means performs a predetermined operation based on a signal from the gaming state detection / determination means, and the control means performs predetermined control based on a signal from the gaming state detection / determination means. The optical transmission means optically connects the gaming state detection / determination means and the operation / control means. The transmission unit of the optical transmission unit transmits a signal from the gaming state detection / determination unit via the optical cable. The receiving unit of the optical transmission unit receives a signal transmitted from the transmitting unit via the optical cable. The power cable supplies the power supply voltage supplied from the receiving unit side to the transmitting unit side. The abnormality detection unit detects a power supply abnormality between the transmission unit and the reception unit via the power cable, and the reception unit operates the output / operation means even in the case of a power supply abnormality in the abnormality detection unit Do not output. That is, the abnormality detection unit detects a power supply abnormality when the power cable between the transmission unit and the reception unit is disconnected, or when the power cable is repeatedly disconnected and connected, and the reception unit Even in the case of power supply abnormality in the detection unit, the output of the reception unit is set as an output that does not operate the operation / control unit. Therefore, even if the power cable between the transmitting unit and the receiving unit is disconnected, or the power cable is repeatedly disconnected and connected, the output of the receiving unit can be set to an output that does not operate the operation / control unit. Therefore, it is possible to prevent the operation / control means from operating due to the disconnection or the like, and the power cable between the transmission unit and the reception unit is disconnected or the power cable is repeatedly disconnected and connected. It is possible to prevent fraudulent acts caused by breaking.

Also, one of the jackpot symbol, the missed reach symbol, and the missed symbol is selected and set as a stop symbol. The stop symbol is a symbol displayed when each symbol row stops symbol variation.

  The jackpot symbol is a symbol for generating a jackpot state that is advantageous to the player after a so-called reach state. Specifically, when all of the symbol row variations are stopped, the displayed symbol combination is a predetermined jackpot combination, that is, when the same type of symbols are lined up along the jackpot line. In some cases, the symbols are combined (for example, symbols “7”, “7”, and “7”). The symbol constituting this combination is the “big hit symbol”. When the jackpot combination is established, the special electric accessory is activated (the jackpot 6 is opened), and it is possible to obtain a jackpot state that is advantageous to the player, that is, to obtain more prize balls.

It has become. The upper lamp decoration 12 has a built-in ball lamp, a winning lamp, and the like for notifying the player of the out-of-ball state and the winning state.

  Here, a configuration which is one of the characteristic portions of the present invention will be described below with reference to FIG. FIG. 3A is a perspective view of a proximity sensor portion in the operation port of the pachinko machine according to the first embodiment, and FIG. 3B is a cross-sectional view taken along line AA of the sensor.

  As shown in FIG. 3A, the operation port 5 (see FIG. 2) includes a proximity sensor 21. The proximity sensor 21 has a casing shape, and includes a case 22 that houses a printed circuit board 27 (see FIG. 3B), which will be described later, and a cover 23. A through hole 24 through which the game ball B passes is provided through the case 22 and the cover 23. The case 22 and the cover 23 are made of resin.

  As shown in FIG. 3B, an annular winding shaft 25 made of resin is disposed around the through hole 24, and an annular coil 26 is also formed on the outer periphery of the winding shaft 25. It is disposed in contact with the winding shaft 25. The coil 26 is connected to an oscillation circuit (not shown) mounted on the printed circuit board 27, and the printed circuit board 27 is mounted with a signal processing unit (not shown) that processes a signal related to the oscillation state in addition to the oscillation circuit. is doing. The signal processing unit is connected to a male connector 28 attached to the rear end of the case 22. The coil 26 and the oscillation circuit constitute an oscillation unit in the present invention.

  As the game ball B passes through the through hole 24, the oscillation state from the oscillation unit changes. Based on this change, the signal processing unit processes a signal related to the oscillation state to output a detection signal. That is, the detection timing is when the oscillation state changes. The operation port 5 corresponds to the operation means in the present invention, and also corresponds to the gaming state detection / determination means in the present invention.

  Next, the electrical configuration of the pachinko machine P will be described with reference to FIG. FIG. 4 is a block diagram showing the electrical configuration of the pachinko machine. As shown in FIG. 4, the pachinko machine P is roughly divided into a main control board C that controls the game content of the pachinko machine P, a payout control board H that controls payout of prize balls and balls, a power supply board 50, and the like. Although not shown, the display control board for controlling the variable display of symbols displayed on the display unit 9a (see FIG. 2), which controls the output of sound effects by a speaker, etc. The sound effect control board, the holding lamps 10a to 10d, and the lamp control board for controlling the lighting of the various lamps 11 to 13. The payout control board H, the display control board, and the sound effect control board correspond to the sub control board in the present invention. The main control board C corresponds to the control means in the present invention.

  The main control board C of the pachinko machine P is equipped with an MPU 31 as a one-chip microcomputer that is an arithmetic unit. The MPU 31 includes a ROM 32 that stores various control programs executed by the MPU 31 and a memory for temporarily storing various data and the like when executing the control program stored in the ROM 32. A certain RAM 33 and the like are incorporated.

  The main control board C is connected to the payout control board H through an input / output port (not shown) so that bidirectional communication is possible. In addition, the main control board C is connected to a plurality of normal winning switches 34, a first type start port switch (proximity sensor) 21, a count switch 35, a power supply board 50, and the like via input / output ports (not shown). Yes.

  The plurality of normal winning switches 34 are switches for detecting balls that have won a plurality of normal winning openings (not shown) provided on the game board 1 and are provided in the vicinity of the entrances of the respective normal winning openings. . The first type start port switch 21 is a switch for detecting a sphere that has passed through the operation port 5, and is provided in the vicinity of the operation port 5. That is, the first type start port switch 21 is also the proximity sensor 21. When a ball is detected by either the normal winning switch 34 or the first type start port switch 21, a command for paying out a winning ball is transmitted from the main control board C to the payout control board H, and five pieces are issued by the payout control board H. The prize ball is paid out.

  The count switch 35 is a switch for detecting a ball that has won a prize winning opening 6. When the ball is detected by the count switch 35, a command for paying out a prize ball is transmitted from the main control board C to the payout control board H, and 15 prize balls are paid out by the payout control board H.

  The payout control board H performs payout control for winning balls and rental balls, and an MPU 36 is mounted as a one-chip microcomputer that is an arithmetic unit. The MPU 36 includes a ROM 37 storing a control program executed by the MPU 36, a RAM 38 used as a work memory, and the like.

  The payout control board H is connected to the main control board C described above via an input / output port (not shown). In addition, the payout control board H is connected to a payout motor 39, a prize ball count switch 40, a power supply board 50 and the like mounted on the payout unit S via an input / output port (not shown).

  The prize ball count switch 40 is a switch for detecting a prize ball paid out by the payout motor 39, and is mounted on the payout unit S together with the payout motor 39. The payout motor 39 is a motor for paying out a prize ball. The drive of the payout motor 32 is controlled by the payout control board H.

  The main control board C, the payout control board H, the power supply board 50, and the like are connected to each other by an electric cable that transmits an electric signal, but the first start port switch 21, that is, the proximity sensor 21 and the main control board C. And are connected by optical cables instead of electrical cables. This will be described in detail with reference to FIG. FIG. 5 is an equivalent circuit diagram of the optical cable and the connector connected thereto.

  As shown in FIG. 5, the optical cable 61 is connected to connectors 62 and 63 at both ends. The optical cable 61 and the connectors 62 and 63 are integrally formed. The connector 62 includes a transmitter 70 that converts an electrical signal into an optical signal, and the connector 63 includes a receiver 80 that converts an optical signal into an electrical signal. Each is formed. That is, the connector 62 has an E / O conversion function, and the connector 63 has an O / E conversion function. The optical cable 61 and the connectors 62 and 63 correspond to the optical transmission means in the present invention.

  The connector 62 and the connector 28 of the proximity sensor 21 are configured to be connectable, and the connector 63 and the connector 64 (see FIG. 7) of the main control board C are configured to be connectable. Since the connector on the proximity sensor 21 side connected to the connector 62 is the male connector 28, the connector 62 is a female connector. The connector 63 can be either a male connector or a female connector according to the shape of the connector 64 of the main control board C.

  The connector 62 serving as the transmission unit 70 includes a light emitting diode 62a for converting an electrical signal, which is a detection signal from the connector 28 of the proximity sensor (first type start port switch) 21, into an optical signal. It is converted into an optical signal by being emitted by 62a. The connector 63 which is the receiving unit 80 includes a photodiode 63a for converting the transmitted optical signal into an electric signal, and the light received by the photodiode 63a is converted into an electric signal.

  The optical cable 61 transmits not only an optical signal but also a power signal in order to secure electric power for moving the start port 5 and the proximity sensor 21. That is, as shown in FIG. 5, in addition to the optical fiber 61a for transmitting an optical signal, a grounding power supply line (GND) and a signal power supply line (Vcc) are arranged in the optical cable. .

  In the case of a single mode optical fiber, as is well known, the optical fiber 61a is composed of a core 61A and a clad 61B that concentrically surrounds the core 61A as shown in FIG. The refractive index of the core 61A is higher than that of the clad 62B. The light propagates through the core 61A while repeating total reflection at the interface between the core 61A and the clad 61B in the optical fiber 61a. Here, the “single mode optical fiber” refers to an optical fiber having a single propagation mode, whereas an optical fiber having a plurality of propagation modes is referred to as a “multimode optical fiber”.

  As is well known, as shown in FIG. 6B, when the optical fiber 61a is bent, the light propagation mode changes. At this time, the total reflection angle becomes θ ′ shown in FIG. 6B instead of θ shown in FIGS. 6A and 6B due to bending. If θ ′ exceeds the critical angle of total reflection, light is refracted at the boundary surface between the core 61A and the clad 61B and transmitted to the clad 61B as shown in FIG. Become a mode. In this way, when the propagation mode is changed to the radiation mode, the light confined in the core 61A is emitted and is not transmitted.

  In order to prevent such a problem, it is preferable to dispose the operation port 5 including the proximity sensor 21 and the main control board C at a position where the optical cable 61 does not substantially bend. Specifically, the operation port 5 is disposed in the game board 1 covered with a transparent plate 1b fitted in the front frame 1a of the pachinko machine P. Normally, the main control board C is connected to the pachinko machine P. As shown in FIG. 7, since the connector 28 of the proximity sensor 21 and the connector 64 of the main control board C are arranged in substantially the same plane and substantially coaxially, as shown in FIG. 5 and the main control board C are disposed, and the optical cable 61 connected to the connectors 62 and 63 is interposed at both ends to connect the connector 28 and the connector 62, and the connector 64 and the connector 63, respectively. That's fine.

  In the first embodiment, the single mode optical fiber has been described. However, the optical fiber 61a may be a multimode optical fiber as shown in FIGS. 8A and 8B. 8A is called a “step index type”, and FIG. 8B is called a “graded index type”. The optical fiber in the case of the step index type is almost the same as the single mode optical fiber except for the diameter of the core 61A, and the diameter of the step index type core 61A is the same as that of the multimode optical fiber because it propagates a plurality of lights. It is larger than the diameter of the core 61A. The optical fiber in the graded index type has a multilayer structure so that the refractive index changes smaller toward the outside in the core 61A.

  As described above, according to the configuration of the pachinko machine P of the first embodiment described above, the operation port 5 having the proximity sensor (first type start port switch) 21 for determining the game state and the game content of the pachinko machine P are controlled. By connecting the main control board C to the main control board C with the optical cable 61 and the connectors 62 and 63 interposed, it becomes difficult to cut the optical cable 61 and connect the illegal optical cable 61 to the cut portion. .

  That is, it is more difficult to manipulate the optical signal transmitted by the optical cable 61 than to manipulate the electrical signal by connecting via an unauthorized cable or board. It is necessary to convert the electrical signal into an electric signal (O / E conversion), manipulate the converted electrical signal, and then convert the manipulated electrical signal into an optical signal again (E / O conversion). In other words, in order to manipulate the optical signal and generate an illegal jackpot, the optical cable 61 is cut and connected via an illegal electric cable or board at the cut position, and the electric cable or board is inserted. Conversion units for O / E conversion and E / O conversion must be connected to the output terminals, which is troublesome.

  As described above, it is difficult to cut the optical cable 61 and connect it with the unauthorized optical cable 61 interposed at the cut portion, so that it is possible to make it difficult to perform an illegal act.

  Further, since the optical signal is not transmitted to the main control board C at the stage where the optical cable 61 is disconnected, there is also an effect that the history of trying to perform an illegal act or performing it can be known. Furthermore, the use of the optical cable 61 also has an effect that it is difficult for noise to enter the optical signal.

  In the first embodiment, the optical transmission means in the present invention is integrally formed from an optical cable 61 that transmits and receives an optical signal between the proximity sensor 21 and the main control board C, and connectors 62 and 63 connected to the optical cable 61. Thus, the connectors 62 and 63 are removed from the proximity sensor 21 and the main control board C, and the optical transmission means formed integrally with the connectors 62 and 63 and the optical cable 61 can be easily replaced. . As the proximity sensor 21 and the main control board C, existing conventional products can be used, so that versatility is enhanced.

  Further, in the first embodiment, the connectors 62 and 63 are integrally formed with a transmission unit 70 for converting an electrical signal into an optical signal and a receiving unit 80 for converting an optical signal into an electrical signal. 21 and the main control board C can be used with existing conventional products, and since only the optical signal is transmitted between the transmission unit 70 and the reception unit 80, between the transmission unit 70 and the reception unit 80. The optical cable can be used for reliable transmission.

  Next, a pachinko machine according to a second embodiment will be described with reference to FIGS. FIG. 10 is an equivalent circuit diagram of the optical cable of the second embodiment and connectors connected thereto. FIG. 11 is a response characteristic diagram of the receiving unit 80 in the case of the three modes of normal state, power supply PB, PC disconnection, and optical fiber disconnection.

  In the first embodiment, the connector 63 of the optical cable 61 is provided with the receiving unit 80. However, in the pachinko machine of the second embodiment, the receiving unit 80 is connected to the connector 64 of the main control board C. The connector 63 of the optical cable 61 is merely a connector, and these points (characteristic features of the second embodiment) are different from those of the first embodiment. Other than that, the first embodiment described above is used. Since it is the same as the example, the second embodiment will explain its feature points in detail.

  As shown in FIG. 10, the connector 62 of the optical cable 61 on the proximity sensor 21 side, that is, the connector 62 of the optical cable 61 connected to the connector 28 of the proximity sensor 21, is similar to the above-described first embodiment. Is provided. As in the first embodiment, the optical cable 61 includes an optical fiber 61a, a signal power line (Vcc), and a ground power line (GND). The connector 63 on the main control board C side of the optical cable 61 is obtained by removing the receiving unit 80 of the first embodiment, and is simply a connecting function (plug-like function) for connecting to the connector 64 of the main control board C. Only. The receiving unit 80 provided in the connector 63 of the optical cable 61 in the first embodiment is provided on the connector 64 on the main control board C side.

  As shown in FIG. 10, the transmitter 70 is provided with a light emitting diode 62a and the like, and the receiver 80 is provided with a photodiode 63a and the like, as in the first embodiment.

  As shown in FIG. 10, the receiver 80 provided on the connector 64 of the main control board C is supplied with power PA (for example, + 5V) from the main control board C, and the ground potential of the main control board C is connected to the ground. Has been. The power PA supplied to the receiver 80 is supplied to the transmitter 70 of the connector 62 of the optical cable 61 via a signal power line (Vcc). The ground potential of the receiving unit 80 is connected to a grounding power line (GND). By doing so, the power supply PB (for example, +5 V) is supplied to the transmission unit 70.

  Further, the power PB supplied to the transmission unit 70 of the connector 62 of the optical cable 61 is supplied as power PC (for example, + 5V) to the proximity sensor 21 via the connector 28 of the proximity sensor 21. The grounding power supply line (GND) of the proximity sensor 21 is connected to the grounding power supply line (GND) of the optical cable 61.

  As shown in FIG. 11, the configuration including the transmission unit 70, the optical cable 61, and the reception unit 80 has a communication abnormality between the transmission unit 70 and the reception unit 80 via the optical cable 61, and a power cable (signal signal). An abnormality detection unit 90 is provided for detecting a power supply abnormality between the transmission unit 70 and the reception unit 80 via the power supply line (Vcc) and the grounding power supply line (GND). For example, when the optical cable 61 is disconnected and the optical communication becomes impossible, the abnormality detection unit 90 detects the optical communication disabled state because the normal communication protocol (protocol) is not satisfied. Further, the abnormality detection unit 90 does not supply the power PB to the transmission unit 70 when the signal power supply line (Vcc) or the ground power supply line (GND) is disconnected, and the transmission unit 70 operates normally. By doing so, optical communication is fundamentally disabled, that is, not only the initial state of normal communication protocol (protocol) is satisfied, but not only the optical communication disabled state but also the power supply disabled state are detected. In the second embodiment, the software is configured to detect the communication abnormality and the power supply abnormality in the abnormality detection unit 90 based on the protocol. The power supply abnormality may be realized by other methods, for example, a power supply abnormality detection circuit or a communication abnormality detection circuit with a hardware electric circuit configuration.

  Next, with reference to FIG. 11, the output of the receiving unit 80 in the case of the three modes of normal state, power supply PB, PC disconnection and optical fiber disconnection will be described.

  First, the output of the receiving unit 80 in a normal state will be described. As shown in the power sources PB and PC at the point K0 in FIG. 11, the power source PA supplied to the receiving unit 80 is supplied to the transmitting unit 70 of the connector 62 of the optical cable 61 via the signal power line (Vcc). (Power PB in FIG. 11) and further supplied to the proximity sensor 21 (Power PC in FIG. 11). Therefore, the power supply PC (for example, + 5V) is normally supplied to the proximity sensor 21, and the proximity sensor 21 operates normally. That is, when the game ball B does not enter the proximity sensor 21, a high level signal is output to the transmission unit 70 (see the sensor output at the location K0 in FIG. 11), and the game ball B enters the proximity sensor 21. When this is done, a pulse-like low level signal is output to the transmitter 70 (see the sensor output at location K1 in FIG. 11). Further, as shown at locations K0 and K1 in FIG. 11, the optical fiber 61a is in a connected state, and the above-described incoming detection signal from the proximity sensor 21 is converted into an optical signal by the transmission unit 70, and the optical fiber 61a is transmitted through the optical fiber 61a. Then, the signal is supplied to the receiving unit 80 of the connector 64 of the main control board C through the connector 63, converted into an electric signal by the receiving unit 80, and the output of the receiving unit 80 remains at a high level at the point K0 in FIG. The signal is output to the main control board C, and the output of the receiving unit 80 is a pulse-like low level signal at the location K1 in FIG. The main control board C performs a predetermined control operation based on the pulsed low level signal.

  Next, the output of the receiving unit 80 when at least one of the power supply PB or the power supply PC is disconnected will be described. First, the output of the receiving unit 80 when the power supply PB is disconnected will be described. As shown in the power sources PB and PC at the location K2 in FIG. 11, for example, when the signal power line (Vcc) is cut and the power source is turned off, the power source PC is not supplied to the proximity sensor 21. Is a low-level signal that falls due to power-off of the power supply PC (see sensor output at location K2 in FIG. 11). At this time, the optical fiber 61a is in a normal connection state as shown in the optical fiber connection state at the point K2 in FIG. The abnormality detection unit 90 detects that even the initial state of the normal communication protocol (protocol) is not satisfied due to the disconnection of the signal power line (Vcc), and not only the optical communication disabled state but also the power supply cannot be performed. Detect state. The receiving unit 80 prevents the output from being changed in the case of a power supply abnormality in the abnormality detection unit 90. Therefore, at the location K2 in FIG. 11, the output of the receiving unit 80 is output to the main control board C with the high level, and the main control board C performs an illegal control due to the disconnection of the signal power line (Vcc). There is no execution.

  When the ground power supply line (GND) is disconnected instead of the signal power supply line (Vcc), the signal power supply line (Vcc) becomes a floating potential, and the transmission unit 70 Since the signal power line (Vcc) is disconnected, the output of the receiving unit 80 is output to the main control board C with the signal being kept at the high level because the signal power line (Vcc) is disconnected. ), The main control board C does not execute unauthorized control. The same applies to the case where the signal power supply line (Vcc) and the ground power supply line (GND) are disconnected, and the output of the receiving unit 80 is output to the main control board C with the signal level being high. The main control board C does not execute unauthorized control due to the disconnection of the power supply line (Vcc).

  Similarly, when the power supply line (power cable) between the proximity sensor 21 and the transmission unit 70 of the optical cable connector 62 is cut, the abnormality detection unit 90 is also connected to the power supply line between the proximity sensor 21 and the transmission unit 70. When the disconnection of the (power cable) is detected, the receiving unit 80 does not change the output when the abnormality detecting unit 90 has a power supply abnormality. Specifically, a function for detecting the disconnection of the power line (power cable) between the proximity sensor 21 and the transmission unit 70 is provided on the transmission unit 70 side, and the reception unit 80 is based on a signal from the transmission unit 70. This can be realized by not changing the output of. Therefore, the output of the receiving unit 80 is output to the main control board C while being at a high level, and the main control board C does not execute unauthorized control due to the disconnection of the signal power line (Vcc).

  Next, the output of the receiving unit 80 when the optical fiber 61a is cut will be described. As shown in the connection state of the optical fiber 61a at the location K3 in FIG. 11, for example, when the optical fiber 61a is cut and optical communication is disabled, the abnormality detection unit 90 does not satisfy the normal communication protocol (protocol). To detect the optical communication disabled state. The receiving unit 80 does not change the output in the case of a communication abnormality in the abnormality detection unit 90. Therefore, at the location K3 in FIG. 11, the output of the receiving unit 80 is output to the main control board C with the high level, and the main control board C does not execute unauthorized control due to the cutting of the optical fiber 61a. .

  As described above, according to the configuration of the pachinko machine P of the second embodiment described above, the transmission unit 70 that transmits a signal from the proximity sensor 21, the reception unit 80 that receives the signal transmitted from the transmission unit 70, An optical cable 61 that connects the transmission unit 70 and the reception unit 80, and an abnormality detection unit 90 that detects a communication abnormality between the transmission unit 70 and the reception unit 80 via the optical cable 61. The reception unit 80 is abnormal. Since the output is not changed in the case of a communication abnormality in the detection unit 90, the abnormality detection unit 90 performs a communication abnormality when the optical cable 61 is disconnected or the optical cable 61 is repeatedly disconnected and connected. The receiving unit 80 is configured not to change the output of the receiving unit 80 in the case of a communication abnormality in the abnormality detecting unit 90. Therefore, it is possible to prevent the output of the receiving unit 80 from changing due to the optical cable 61 being cut or disconnected, or repeatedly connected. As a result, the output of the receiving unit 80 does not change even if the optical cable 61 is cut or the optical cable 61 is repeatedly cut and connected, so the optical cable 61 is cut or the optical cable is cut and connected. It is possible to prevent fraudulent acts caused by repeated actions.

  The optical cable 61 includes a power cable (signal power line Vcc, ground power line GND) for supplying the power voltage supplied from the receiver 80 side to the transmitter 70 side. A power supply abnormality between the transmission unit 70 and the reception unit 80 via the signal power supply line Vcc and the ground power supply line GND is also detected, and the reception unit 80 detects a power supply abnormality in the abnormality detection unit 90. Since the output is not changed, the anomaly detection unit 90 can disconnect the optical fiber 61a and the power cable between the transmission unit 70 and the reception unit 80, or disconnect and connect the optical fiber 61a and the power cable. If repeated, a communication abnormality or a power supply abnormality is detected, and the receiving unit 80 prevents the output of the receiving unit 80 from being changed in the case of a communication abnormality or power supply abnormality in the abnormality detection unit 90. Therefore, even if the optical fiber 61a and the power cable between the transmitting unit 70 and the receiving unit 80 are cut, or the optical fiber 61a and the power cable are repeatedly cut and connected, the output of the receiving unit 80 changes. Therefore, the optical fiber 61a and the power cable between the transmitting unit 70 and the receiving unit 80 are disconnected, and the illegal operation caused by repeated disconnection and connection of the optical fiber 61a and the power cable is prevented. it can.

  Further, the proximity sensor 21 is connected so that the power supply voltage supplied to the transmitting unit 70 side is supplied via a power cable (signal power line Vcc, ground power line GND), and further detects abnormality. The unit 90 also detects a power supply abnormality between the proximity sensor 21 and the transmission unit 70, and the reception unit 80 prevents the output from being changed in the case of a power supply abnormality in the abnormality detection unit 90. Since the output of the receiving unit 80 does not change even if the power line between the transmitter and the transmitting unit 70 is disconnected or the power line is disconnected and connected repeatedly, the proximity sensor 21 and the transmitting unit are not changed. It is possible to prevent an illegal act caused by disconnecting the power line between the power supply line 70 and the power line and repeatedly disconnecting and connecting the power line.

  Even when the connectors 62 and 63 of the optical cable 61 are disconnected, or when the optical fiber 61a, the signal power supply line (Vcc), and the ground power supply line (GND) are all disconnected, It has the same effect as the case and is excellent in anti-fraud measures.

  A connector 62 connected to the proximity sensor 21 is provided at one end of the optical cable 61, and a connector 63 connected to the main control board C is provided at the other end of the optical cable 61. The connector 62 is provided with a transmission unit 70, and the main control board C is provided with a connector 64 that is connected to the optical cable 61, and the connector 64 is provided with a reception part 80, so that the main control board C of the optical cable 61 is provided. Compared with the case where the receiving unit 80 is provided in the connector 63 on the side, the countermeasure against fraud is further improved. That is, when the receiving unit 80 is provided in the connector 63 on the main control board C side of the optical cable 61, the connector 63 on the main control board C side of the optical cable 61 is removed and an illegal signal is transmitted from the connector 64 on the main control board C. However, when the receiving unit 80 is provided in the connector 64 of the main control board C, even if such an incorrect signal is input from the connector 64 of the main control board C, an incorrect signal is generated. Since the output of the receiving unit 80 is not changed only by being input to the receiving unit 80, the main control board C is not illegally operated by an unauthorized signal, and the countermeasure against fraud is excellent.

  The present invention is not limited to the above embodiment, and can be modified as follows.

< 1 > In the first embodiment described above, the proximity sensor 21 of the operating port 5 and the main control board C are connected via the optical cable 61 and the connectors 62 and 63. In the second embodiment described above, the operation is performed. The proximity sensor 21 of the mouth 5 and the main control board C are connected via the optical cable 61 and the connectors 62 and 64. However, as long as the pachinko machine P is controlled, the proximity sensor 21 is not limited to the main control board C. For example, the proximity sensor 21 and the payout control board H may be connected via the optical cable 61 and the connectors 62 and 63. However, in this case, since a means (electric cable in the embodiment) is connected between the main control board C and the payout control board H which is the sub-control board, the means is cut and the cut is made. There is a risk of connecting with an illegal cable or board in place.

Therefore, in this case, it is preferable to configure as in the embodiment. If configured as in the modification (1), in addition to connecting the proximity sensor 21 and the main control board C with the optical cable 61, the main control board C and the payout control board H are connected with the optical cable 61. Thus, the optical transmission means is an optical cable between the main control board C and the payout control board H. Therefore, even if it is configured as in the modified example < 1 > , it is possible to make it difficult to cheat.

< 2 > In the above-described first embodiment, the proximity sensor 21 of the operating port 5 and the main control board C are connected via the optical cable 61 and the connectors 62 and 63, thereby making it difficult to perform an illegal act. However, when the optical cable 61 is disconnected, the control boards (main control board C, payout control board H, etc.) are set so that the pachinko machine P is not operated or the payout of the game ball B to the player is stopped. ) May be configured.

  For example, when an optical signal is not transmitted from the first type start port switch 21, that is, the proximity sensor 21 to the main control board C through the optical cable 61 for a predetermined time or more, the power supply board 50 except for the backup power supply. May be stored in the ROM 32 on the main control board C side so that the pachinko machine P is not operated when the optical cable 61 is disconnected.

  Further, for example, when an optical signal is not transmitted from the proximity sensor 21 for a predetermined time or longer, a control program for not driving the payout motor 39 is stored in the ROM 37 on the payout control board H side, and the player is disconnected when the optical cable 61 is disconnected. You may make it stop paying | paying out the game ball B to. In this case, since the payout control board H directly performs payout control, the proximity sensor 21 and the payout control board H are connected by the optical cable 61 rather than connecting the proximity sensor 21 and the main control board C by the optical cable 61. It is preferable to connect. If the proximity sensor 21 and the main control board C are connected by the optical cable 61 as in the above-described embodiment, the main control board C and the payout control board H are connected as described in the modification (1). It is preferable to connect with an optical cable 61.

  By configuring the main control board H or the payout control board H in this way, it is possible to know the history of trying to perform an illegal act or having done so, do not operate the pachinko machine P, or pay out the game ball B to the player By stopping, cheating itself can be reliably prevented.

< 3 > In each of the embodiments described above, the optical cable 61 includes a grounding power supply line (GND) and a signal power supply line (Vcc) in addition to the optical fiber 61a for transmitting an optical signal. By setting, not only the optical signal but also the power signal is transmitted, but only the optical fiber 61a may be disposed inside so as to transmit only the optical signal. In this case, a power source for moving the start port 5 and the proximity sensor 21 is directly connected from the power supply board 50 to the start port 5 or the proximity sensor 21.

< 4 > In each of the above-described embodiments, the proximity sensor 21 includes the annular coil 26 provided around the through hole 24 as shown in FIG. 3, but the through hole 24 as shown in FIG. The coil 26 may be provided in the proximity position.

< 5 > In each of the above-described embodiments, the proximity sensor 21 is used to detect the game ball B, which is a prize ball. However, the detection sensor is not limited to the proximity sensor as long as it is a commonly used detection unit that detects the game ball. . For example, it may be a transmission type sensor composed of a light projecting element and a light receiving element disposed opposite to each other with a game ball interposed therebetween, or a light projecting element and a light receiving element respectively disposed toward the game ball It may be a reflection type sensor consisting of the above, or a contact type sensor in which a signal to be detected changes when the game ball comes into contact.

  In the case of a transmissive sensor, the light receiving element receives the light from the light projecting element when the game ball does not pass, and the light from the light projecting element is blocked by the game ball when the game ball passes and the light receiving element is Does not receive light. That is, the detection timing is when the light receiving element is turned off.

  In the case of a reflective sensor, the light receiving element does not receive the light from the light projecting element when the game ball does not pass, and the light from the light projecting element is reflected by the game ball when the game ball passes and the light receiving element Receive light. That is, the detection timing is when the light receiving element is turned on.

  In the case of a contact-type sensor, a signal to be detected changes when the game ball comes into contact. That is, the detection timing is when the signal changes. Note that, as an example of the change in signal, there is a change from ON to OFF when touched, and as another example, there is a change from OFF to ON. In the case of such a contact-type sensor, a lever is disposed inside the through hole through which the game ball passes, and the signal is switched from ON to OFF by contacting the lever when the game ball passes through the through hole. Or what is necessary is just to comprise so that it may change from OFF to ON. Of course, there is no need to change digitally.

< 6 > In each of the above-described embodiments, the game state detection / determination means in the present invention is an operation port 5 that determines the operation state of the pachinko machine P by detecting the passed award ball, that is, the game ball B, The target connected to the optical cable other than the control means (for example, the main control board C and the payout control board H) in the present invention is the operation port 5, but the gaming state detection / determination means that is the target connected to the optical cable. Is not limited to the operation means represented by the operation port 5.

  The gaming state detection / determination means to be connected to the optical cable may be detection means for detecting a gaming state. For example, the gaming state detection / determination means may be a normal winning switch 34 that detects a gaming state in which five prize balls are paid out, or a count switch 35 that detects a gaming state in which 15 prize balls are paid out. It may be. In these cases, the normal winning switch 34 or the count switch 35 and the main control board C are connected with an optical cable, and each time a game ball wins the normal winning opening or the big winning opening 6, the detection signal is an optical signal. And transmitted by the optical cable 61. Further, the gaming state detection / determination means triggers the variable display of the normal identification information (for example, the normal symbol) on the normal identification information variation display device (for example, the normal symbol variation display device) based on the winning of the game ball. A normal symbol winning detection switch (sensor) may be used. For example, when the normal symbol becomes a winning symbol, the blade 7 of the working port 5 opens and closes, and when the normal symbol comes off and is a symbol, the blade 7 of the working port 5 does not open and close. The normal symbol winning detection switch (sensor) and the main control board C are connected by an optical cable, and each time a game ball wins a normal symbol winning opening, the detection signal is transmitted as an optical signal through the optical cable 61.

  In addition, it is illegal to connect via an unauthorized electric transmission means (cable) or an electrical connection part (for example, a board) so as to change from a normal state unfavorable to the player to an advantageous special gaming state (for example, a big hit state). Therefore, the target connected to the optical cable other than the control means is limited to the gaming state detection / determination means for detecting or determining the gaming state. Therefore, it is not necessary to connect other detection means and means (for example, sound generating means [for example, a speaker], illumination means (for example, a lamp), etc.) that are to be electrically connected to the control means with an optical cable.

< 7 > Further, a fraud prevention means for preventing fraud may be provided separately. By separately providing a fraud prevention means, it is possible to make fraud more difficult. Examples of fraud prevention means include the following.

  For example, a fluorescent paint may be applied to the surface of the optical cable 61 shown in FIG. By having the fluorescent color on the surface in this way, the optical cable 61 is easily noticeable and attracts attention, and fulfills the function of fraud prevention means in the present invention. In FIG. 5 and the like, the optical fiber 61a, the grounding power supply line (GND) and the signal power supply line (Vcc) are disposed in the optical cable 61. However, the optical fiber 61a, GND, Vcc, etc. If the optical fiber 61a is simply arranged in parallel, or if the optical fiber 61a is simply arranged in parallel, a fluorescent paint may be applied to the surface of the optical fiber 61a, GND, Vcc, or the like. If the purpose is not to simply replace the optical transmission means, the optical cable 61 and the connectors 62 and 63 do not have to be configured integrally. Further, a fluorescent paint may be applied to the surfaces of the connectors 62 and 63 to fulfill the function of fraud prevention means.

  Further, for example, the receiving unit 80 shown in FIG. 5, that is, the connector 63 may be sealed (molded) with a transparent resin at a circuit constituent part that constitutes the receiving unit 80. By molding in this way, the circuit components are easily noticeable through the resin. Therefore, even if a circuit configuration part is illegally connected by changing it to an illegal circuit configuration part or illegally modified, the circuit configuration part is easily noticeable. Since it is immediately known that the circuit component has been performed and the circuit component part is easily noticeable, fraud in the circuit component part itself can be prevented. The connector 63 on the receiving unit 80 side configured in this way functions as a fraud prevention means in the present invention. In addition, by configuring the connector 63 on the receiving unit 80 side on the lower side in the signal transmission direction in this way, the connector 62 on the transmitting unit 70 side on the upper side is configured more illegally. You can make it harder to act. Note that not only the connector 63 on the receiving unit 80 side described above but also the connector 62 on the transmitting unit 70 side, the circuit components constituting the transmitting unit 70 may be molded with a transparent resin.

  Further, for example, the connector 63 on the receiving unit 80 side is attached to the main control board C side in the case of the above-described embodiment, but the connector 63 which is also on the main control board C side may be specially processed. Good. Here, the special processing may be molding processing for sealing circuit components with resin as described above, and when the connector 63 is removed from the main control board C, it may be reconnected to the main control board C. Processing that cannot be performed. In any case, it becomes difficult to remove and connect an illegal optical cable or the like as compared with a highly versatile connector or a commercially available connector, and the function of the illegal act preventing means in the present invention is achieved. Further, not only the connector 63 on the main control board side, that is, the connector 63 on the receiving unit 80 side, but also the connector 63 on the proximity sensor 21 side, that is, the connector 62 on the transmitting unit 70 side, may be subjected to the special processing described above. .

  As an example of a configuration in which the connector 63 cannot be reconnected to the main control board C when the connector 63 is detached from the main control board C, there is a structure in which the connector 63 itself is destroyed when it is detached. In any case, it is difficult to connect an unauthorized optical cable or the like simply by removing the connector 63 from the main control board C so that it cannot be connected to the main control board C again.

< 8 > In the second embodiment described above, the abnormality detection unit 90 performs communication abnormality due to disconnection of the optical fiber 61a and power abnormality due to disconnection of the power cable (signal power line Vcc, grounding power line GND). However, when it is desired to detect only a communication abnormality caused by cutting of the optical fiber 61a or the like, only a communication abnormality caused by cutting of the optical fiber 61a or the like may be detected. When it is desired to detect only a power supply abnormality caused by disconnection (signal power line Vcc, ground power line GND) or the like, the power cable (signal power line Vcc, ground power line GND) is disconnected. Only a power supply abnormality due to the above may be detected.

< 9 > In each of the embodiments described above, the main control board C or the like is adopted as the control means, but a relay board or the like may be adopted as the operation means. The relay board is disposed between the proximity sensor 21 and the main control board C, and relays a signal from the proximity sensor 21 and outputs it to the main control board C. Further, as the power sources PA, PB, and PC, for example, + 5V (volt) is used, but other voltage values such as + 12V may be appropriately adopted. In addition, it is more excellent in countermeasures against fraud if the proximity sensor 21 and the relay board are connected by the optical cable 61 of the above-described embodiment, and the relay board and the main control board C are connected by the optical cable 61.

< 10 > In each of the above-described embodiments, the receiving unit 80 is configured not to change the output in the case of a communication abnormality in the abnormality detecting unit 90. However, the receiving unit 80 communicates with the abnormality detecting unit 90. In the case of abnormality, the output may be an output that does not operate the operation / control means (for example, the main control board C).

< 11 > The present invention may be implemented in a pachinko machine of a type different from the above embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after a jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a ball is won in a predetermined area. Further, in addition to pachinko machines, various game machines such as an arrangement ball type pachinko machine, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are integrated may be used.

  In the slot machine, for example, the symbol is changed by operating the operation lever in the state where the symbol effective line is determined by inserting coins, and the symbol is stopped and confirmed by operating the stop button. is there. Accordingly, the basic concept of the slot machine is that “a variable display means for confirming and displaying a symbol after a symbol string composed of a plurality of symbols is displayed in a variable manner, and the symbol resulting from the operation of the starting operation means (for example, an operating lever). The change of the symbol is stopped due to the operation of the stop operating means (for example, the stop button) or after a predetermined time has elapsed, and the fixed symbol at the time of the stop is a specific symbol Is a slot machine provided with special game state generating means for generating a special game state advantageous to the player. In this case, the game medium is typically a coin, a medal or the like.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a variable display means for displaying a fixed symbol after displaying a variable symbol row consisting of a plurality of symbols is provided, and a handle for launching a ball is provided. What is not provided. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the variation of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or the predetermined amount With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  The present specification also discloses an invention relating to the following gaming machines.

  (0) In a gaming machine comprising gaming state detection / determination means for detecting or determining a gaming state and control means for controlling the gaming machine,
  An optical transmission means for connecting the gaming state detection / determination means and the control means;
  The optical transmission means includes an optical cable for transmitting an optical signal between the gaming state detection / determination means and the control means, and connectors connected to both ends of the optical cable,
  Furthermore, it comprises fraud prevention means for preventing fraudulent acts related to the optical transmission means,
  The gaming machine characterized in that the fraud prevention means is configured by sealing both connectors connected to the gaming state detection / determination means and the control means with a transparent resin.

  According to the invention described in (0), the optical transmission means includes the optical cable that transmits and receives an optical signal between the gaming state detection / determination means and the control means, and connectors connected to both ends of the optical cable.
