The present invention relates to a gaming machine equipped with a device.

  2. Description of the Related Art Conventionally, a gaming machine is mounted with a control case on which a control element such as a CPU, ROM, or RAM that controls the operation contents (game effects and various notification operations) of the gaming machine is mounted in a storage case. . In such a gaming machine, the storage case is opened and the control element or the control board is replaced with an illegally manufactured control element or control board, or the control apparatus itself is replaced with an illegally manufactured control apparatus. Cheating may occur. In addition, there has been a third party who thinks that illegally gaining a game medium such as a game ball or a game medal by using the illegally manufactured control element, control board, or control device to obtain an unfair advantage. In addition, the fraudulent acts are often performed at night when monitoring at a game shop is absent and the monitoring becomes light. Furthermore, at night amusement stores, there is often no power supply to gaming machines, and it is difficult to notify (notify) employees of the opening of gaming machine doors, such as when operating at a gaming store. It is in the situation. For this reason, even at night game stores, there is a gaming machine that can prevent the cheating (for example, Patent Document 1).

In Patent Document 1, a gaming machine opening detection device that detects opening and closing of a gaming machine door notifies whether or not the gaming machine door has been opened and closed. A gaming machine open detection device energizes a switch that opens and closes in conjunction with opening and closing of a gaming machine door, an electrolytic capacitor that is charged by power supplied from an external power source, a normally open contact, and a contact state of the contact. Thus, a latching relay having a coil that can be switched from a normal contact state to a reverse contact state is provided. In the latching relay, when the door of the gaming machine is in an open state, the contact state is in an open state, and when the door is in a closed state, it is in a closed state, which is a contact state opposite to the open state. Then, based on the contact state of the latching relay, in the open state, the fact that the door is opened or the door is opened is outputted to the outside. Further, in Patent Document 1, even when power is not supplied from an external power source (night game shop), power is supplied to the latching relay by power discharged from the electrolytic capacitor provided in the gaming machine open detection device. I can do it.

When the fraud detection signal is input, the hall computer HC recognizes that the main control board 31 has been removed, and the main control board 31 may have been replaced with a fraudulent control board that has been illegally manufactured. You can remember (recognize) things. Based on the record (memory) of the hall computer HC, the store clerk of the amusement store can recognize that an illegal act may be performed.

Next, the configuration of the storage case 37 that stores the main control board 31 and the security device S will be described with reference to FIGS.
As shown in FIGS. 3A and 3B, the storage case 37 is composed of a main body B and a lid C. The main control board 31 is covered with the housing case 37 as a whole, and prevents the unauthorized attachment of control elements (CPU, ROM, RAM, etc.) from the outside. For this reason, it is caulked in the housing case 37. The housing case 37 is a part of the main control board 31 and other boards (display control board 32, lamp control board 33, sound control board 34, power supply board 35, power switch board 36, payout control board 38, board use. A connection portion 31a (shown in FIG. 2) for outputting various signals to the external terminal plate 40 and the frame external terminal plate 41) is exposed to the outside. In addition, the housing case 37 is formed with hook-shaped insertion ribs 37c protruding outward.

Next, the configuration of the security device S will be described.
3A and 3B are simplified sectional views of the storage case 37 (main control board 31) and the security device S (elements mounted on the main control board 31 are omitted). In the security device S, a concave rib receiving portion Sa is formed, and the insertion rib 37c of the housing case 37 can be inserted into the rib receiving portion Sa. The rib receiving portion Sa is formed with a through-hole Sb in which the rib-side arm portion 42a shown in FIGS. 4A and 4B can move in and out. The rib receiving portion Sa is formed in such a size that the inserting rib 37c does not contact the inner surface of the rib receiving portion Sa when the inserting rib 37c is inserted into or extracted from the rib receiving portion Sa. ing.

  Further, the security device S is equipped with an operating arm 42 and a detection switch 44. As shown in FIGS. 4A and 4B, the operating arm 42 includes a rib side arm portion 42a, and one end of the rib side arm portion 42a is connected to one end of the middle arm portion 42b via a connecting portion 42d. It is connected. Further, the other end of the middle arm portion 42b is connected to the switch side arm portion 42c through a connecting portion 42e. In the front view, the rib side arm portion 42a and the switch side arm portion 42c are provided with a connecting portion 42d and a connecting portion 42e, respectively. And the said connection part 42d and the connection part 42e are standingly arranged so that it may protrude from the rib side arm part 42a and the switch side arm part 42c. Further, elongated holes 42f and 42g extending along the longitudinal direction of the middle arm portion 42b are formed at both ends of the middle arm portion 42b. The connecting portions 42d and 42e are slidably fitted in the long holes 42f and 42g, respectively. For this reason, when the connecting part 42d and the connecting part 42e slide in the long holes 42f and 42g, the rib side arm part 42a, the middle arm part 42b, and the switch side arm part 42c constitute a link mechanism that expands and contracts. is doing.

  In addition, a pair of projecting portions 42h that project perpendicularly from the front surface 42i and the back surface 42j of the middle arm portion 42b are formed at the center of the middle arm portion 42b. The protrusion 42h has a circular shape and is rotatably inserted into a receiving portion (not shown) in the security device S to support the middle arm portion 42b so as to be swingable. In addition, a spring (winding spring) 43 is disposed on the protrusion 42h formed on the middle arm portion 42b, and a fixed end 43a that is one end of the spring 43 is fixed at a predetermined position in the security device S. In addition, the biasing end 43b, which is the other end of the spring 43, is fixed to the surface 42i of the middle arm part 42b on the side of the elongated hole 42g formed in the middle arm part 42b.

  As shown in FIGS. 4 (a) and 4 (b), the detection switch 44 includes a switch body 44a, a detection piece 44b, and a detection unit 44c, and the detection piece 44b contacts the detection unit 44c. It is a contact type switch that detects That is, the detection switch 44 is “ON” when the detection piece 44b is in contact with the detection unit 44c, and is “OFF” when the detection piece 44b is not in contact with the detection unit 44c. . In this embodiment, fraud is detected when the detection switch 44 is “ON”, and fraud is not detected when the detection switch 44 is “OFF”. That is, the detection switch 44 is “ON” when the housing case 37 that houses the main control board 31 is removed from the mechanism frame 25.

  Further, the detection switch 44 is fixed in the security device S so as to be positioned on the operation track of the switch side arm portion 42c of the operating arm 42 by a fixing means (for example, a support tool) not shown. For this reason, the switch side arm portion 42c of the operating arm 42, the tip end portion 44d of the detection piece 44b, and the detection portion 44c are positioned on a straight line. Therefore, as shown in FIG. 3A and FIG. 4A, the state where the switch-side arm portion 42c of the operating arm 42 and the detection switch 44 are separated from each other is normal when the detection switch 44 does not detect fraud. It becomes a state. On the other hand, as shown in FIGS. 3 (b) and 4 (b), the state where the switch-side arm portion 42c of the operating arm 42 and the detection switch 44 are in contact with each other indicates that the detection switch 44 detects an unauthorized operation. It becomes a detection state (abnormal state).

  In this embodiment, when the housing case 37 that houses the main control board 31 is attached (fixed) to the mechanism frame 25 (pachinko machine 10), the insertion rib 37c of the housing case 37 is the rib of the security device S. It is inserted in the receiving part Sa. For this reason, the rib side arm portion 42a of the operating arm 42 moves in the sinking direction (in the direction approaching the detection switch 44) by the insertion rib 37c. In conjunction with the operation of the rib side arm portion 42 a, the middle arm portion 42 b swings and the switch side arm portion 42 c moves in a direction away from the detection switch 44. Therefore, the switch side arm portion 42c, the detection piece 44b (tip portion 44d), and the detection portion 44c are in the normal state (FIGS. 3A and 4A). In the normal state, the spring 43 generates an urging force for moving the switch-side arm portion 42c in a direction approaching the detection switch 44 due to the proximity of the fixed end 43a and the urging end 43b of the spring 43. It is like that. Further, the urging force generated by the spring 43 is the force (the force with which the housing case 37 is fixed to the mechanism frame 25) that the rib side arm portion 42a is pushed in the sinking direction (direction approaching the detection switch 44) by the insertion rib 37c. ) Smaller than For this reason, in the normal state, the operation arm 42 can maintain the normal state.

  On the other hand, when the accommodation case 37 that accommodates the main control board 31 is not attached (fixed) to the mechanism frame 25 (the pachinko machine 10) (when the accommodation case 37 is fixed to the mechanism frame 25 is released), the accommodation case The insertion ribs 37c of 37 are not inserted into the rib receiving portion Sa of the security device S (exit from the rib receiving portion Sa). For this reason, the switch-side arm portion 42c of the operating arm 42 moves in a direction approaching the detection switch 44 by the biasing force generated by the spring 43 (the force acting in the direction in which the fixed end 43a and the biasing end 43b are separated). Therefore, it becomes an improper detection state (FIG. 3B and FIG. 4B) in which the switch side arm portion 42c, the detection piece 44b (tip portion 44d) and the detection portion 44c come into contact.

  Further, in conjunction with the movement of the switch side arm portion 42c, the middle arm portion 42b swings about the protrusion 42h as the rotation center (swings in the direction of arrow Y1 in FIG. 4B), and the rib side arm portion 42a. Moves in the projecting direction (the direction away from the detection switch 44 in the direction of arrow Y2 in FIG. 4B). Therefore, the rib side arm portion 42a is in a state of protruding from the rib receiving portion Sa (a state of moving in the protruding direction). In the unauthorized detection state, the spring 43 has the fixed end 43a and the biasing end 43b of the spring 43 spaced apart from each other, but the spring 43 tries to move the switch side arm portion 42c in a direction approaching the detection switch 44. The power is generated. For this reason, the switch side arm part 42c can maintain the unauthorized detection state by the urging force of the spring 43.

  Next, in the pachinko machine 10 of the present embodiment, a control configuration (electrical configuration and mechanical configuration) for detecting a fraud detection state by the security device S will be described with reference to FIGS. In FIG. 5, the electrically connected parts are indicated by solid lines, and the mechanically connected parts are indicated by broken lines.

  The security device S is connected to a power supply board 35 to which power is supplied from the outside of the pachinko machine 10 (power supply AC), and power (5 [V] in this embodiment) is supplied from the power supply AC through the power supply board 35. It has come to be. Further, the security device S is mechanically connected to the main control board 31 via the housing case 37 (by the insertion rib 37c). That is, when the insertion rib 37c is inserted into the rib receiving portion Sa, the security device S and the main control board 31 are mechanically connected, and the insertion rib 37c is not inserted into the rib receiving portion Sa. The security device S and the main control board 31 are not mechanically connected. Further, the security device S is electrically connected to the frame external terminal plate 41, and the frame external terminal plate 41 is electrically connected to the hall computer HC. For this reason, the security device S is connected to the hall computer HC via the frame external terminal plate 41. Since the main control board 31 and the security device S are not electrically connected, electrical signals cannot be exchanged with the main control board 31 from the frame external terminal board 41 via the security device S. It has become.

  The security device S includes a fraud detection circuit F including a detection switch 44, a relay circuit 45, a signal output unit 46, a standby power supply C1, and an output power supply C2. When the mechanical connection of the main control board 31 is released (when the security apparatus S is removed from the mechanism frame 25), the main control board 31 is removed from the mechanism frame 25 by the fraud detection circuit F of the security apparatus S. This is detected, and the detection result is output to the hall computer HC.

Next, the detection switch 44 constituting the fraud detection circuit F will be described.
The detection switch 44 is in a non-energized state (a state in which no current flows) when the detection piece 44b (tip portion 44d) and the detection unit 44c are not in contact (in a normal state). On the other hand, when the detection piece 44b (tip portion 44d) and the detection portion 44c are in contact with each other (when the detection switch 44 is in an illegal detection state), the detection switch 44 is in an energized state (a state in which a current flows). That is, in the fraud detection circuit F in which the detection switch 44 is incorporated, when the detection switch 44 is in the normal state, the detection switch 44 is short-circuited (not electrically connected). State). When the state of the detection switch 44 is an unauthorized detection state, the portion of the detection switch 44 is in an electrically connected state that is not short-circuited. That is, in the present embodiment, the detection switch 44 that causes the fraud detection state functions as a state detection unit.

Next, the relay circuit 45 constituting the fraud detection circuit F will be described.
The relay circuit 45 includes a first coil L1 and a second coil L2, and a relay terminal P1 and a relay terminal P2 are provided corresponding to the coils L1 and L2, respectively. In addition, the relay terminals P1 and P2 are provided with magnetic bodies M1 and M2 that generate magnetic force, respectively, and form a contact state by contact of the contact portion P with either the relay terminal P1 or the relay terminal P2. A changeover switch LSW is provided. The contact portion P is attracted by magnetic force, and forms each contact state by being attracted by magnetic force.

  The relay circuit 45 of this embodiment is a two-winding latching relay circuit. In the relay circuit 45, when the first coil L1 is energized, a magnetic force passing through the first coil L1 is generated. For this reason, the contact point P of the changeover switch LSW is attracted to the relay terminal P1 side by the magnetic force passing through the first coil L1. As a result, a first contact state in which the relay terminal P1 and the contact point P of the changeover switch LSW are in contact is formed. The first contact state includes a circuit unit (signal output unit 46 and output power source C2 shown in FIGS. 6 and 7) connected to the relay terminal P1, and a circuit unit (FIGS. 6 and 7 connected to the changeover switch LSW). The power supply board 35) shown in FIG. On the other hand, in the relay circuit 45, when the second coil L2 is energized, a magnetic force passing through the second coil L2 is generated. For this reason, the contact point P of the changeover switch LSW is attracted to the relay terminal P2 side by the magnetic force passing through the second coil L2. As a result, a second contact state in which the relay terminal P2 and the contact point P of the changeover switch LSW are in contact is formed. The second contact state includes a circuit part connected to the relay terminal P2 (short circuit terminal P4 shown in FIGS. 6 and 7) and a circuit part connected to the changeover switch LSW (power supply board 35 shown in FIGS. 6 and 7). Is in a state where is electrically connected.

  Moreover, in this embodiment, when each contact state is formed by the magnetic bodies M1 and M2 provided in the relay terminals P1 and P2, the formed contact state can be maintained so as not to be released. . That is, after the first state is formed, the first contact state formed by the contact portion P is maintained until the second coil L2 is energized and the second contact state is formed. It is like that. On the other hand, after the second state is formed, the second contact state formed by the contact portion P is maintained until the first coil L1 is energized and the first contact state is formed. It is like that. Note that the magnetic force of the magnetic bodies M1 and M2 generates a magnetic force that is weaker than the magnetic force generated by the first coil L1 and the second coil L2. Therefore, even when the contact states formed by the magnetic bodies M1 and M2 are maintained, the contact state corresponding to the energization of the first coil L1 and the second coil L2 is formed by the changeover switch LSW. It has become.

  In addition, as the latching relay circuit of this embodiment, a latching relay circuit using permanent magnets for the magnetic bodies M1 and M2 (for example, DS relay manufactured by Matsushita Electric Works Co., Ltd.) is used. The relay circuit 45 of the present embodiment has a characteristic that it is small compared with an object in which the contact state of the changeover switch LSW is held by a permanent magnet. Further, the relay circuit 45 of the present embodiment has a characteristic that driving power for driving the contact portion P for switching the changeover switch LSW (forming the first contact state or forming the second contact state) is small. Yes. The drive voltage for operating the relay circuit 45 (switching the contact state) can be driven at a voltage lower than the rated voltage which is the withstand voltage of the standby power supply C1 as the backup power supply. . Therefore, even if the electric double layer capacitor has a lower withstand voltage than the electrolytic capacitor, the changeover switch LSW of the relay circuit 45 can be switched.

  In addition, the latching relay circuit of this embodiment reduces the power consumption for securing the driving power and reduces the power consumption of the power source AC (standby power source C1) serving as the supply source, so that the changeover switch can be used. LSW (contact point part P) can be switched. In the relay circuit 45 of the present embodiment, the contact portion P can be switched with a rated voltage of 5V and a voltage of 3.5V or more as a driving voltage. Further, the relay circuit 45 of the present embodiment is strong against externally applied vibrations, and can also prevent problems such as the contact state being released by vibrations. In other words, it has resistance to vibrations when the pachinko machine 10 is transported. Further, if the relay circuit 45 is a latching relay circuit in which the drive voltage for switching the changeover switch is a low voltage (lower than the withstand voltage of the standby power supply C1), the relay circuit 45 and the configuration (the magnetic bodies M1 and M2 are The electromagnet etc.) may be different. In the present embodiment, the relay circuit 45 that forms contact states and holds each contact state functions as a detection result holding unit.

Next, the signal output unit 46 constituting the fraud detection circuit F will be described.
The signal output unit 46 includes a light emitting element (not shown) including an LED lamp that emits light when power is supplied to the signal output unit 46, and a light detection element (not shown) that detects light emitted from the light emitting element. ). The signal output unit 46 is a phototransistor that can output a fraud detection signal based on the detection result of the light detection element. In the present embodiment, when power is supplied to the signal output unit 46, the light emitting element emits light. When the light emission detecting element detects the light emission of the light emitting element, the phototransistor causes the hall computer through the frame external terminal plate 41. A fraud detection signal can be output to the HC. The signal output unit 46 can output a fraud detection signal while the light detection element detects light. That is, the fraud detection signal is output to the hall computer HC while power is supplied to the signal output unit 46. In the present embodiment, the signal output unit 46 that notifies the hall computer HC of the contact state of the changeover switch LSW functions as an information notification unit.

Next, the standby power supply C1 constituting the fraud detection circuit F will be described.
The standby power source C1 of the present embodiment is an electric double layer capacitor (rated voltage 5.5 [V], electric capacity 0.22 [F]) that can store a larger charge than an electrolytic capacitor. For this reason, when using an electric double layer capacitor as a power supply, it is possible to supply power to the fraud detection circuit F over a long period of time as a power supply means compared to an electrolytic capacitor. In the security device S of the present embodiment, when the power supply AC and the power supply substrate 35 are not connected, or when the power supply switch substrate 36 is not in a state of supplying power, the security device S is supplied with power. Even if not, power can be supplied from the standby power source C1.

Next, the output power supply C2 constituting the fraud detection circuit F will be described.
The output power source C2 of this embodiment is an electrolytic capacitor (rated voltage 16 [V], electric capacity 10 [μF]) that can store electric charge. Further, the output power source C2 can supply power to the signal output unit 46, and even if the power is not supplied to the security device S (the power is not supplied to the signal output unit 46), the signal Electric power can be supplied to the output unit 46. In the present embodiment, the output power source C2 that supplies power to the signal output unit 46 is the notification unit power source.

Next, the circuit configuration of the fraud detection circuit F of the security device S will be described with reference to FIGS.
The fraud detection circuit F of the security device S of the present embodiment can be supplied with power from an external power supply AC via the power supply board 35. The power supply board 35 has a pair of power supply side terminals E1 and E2, and is connected to circuit side terminals N1 and N2 of the fraud detection circuit F, respectively. The security device S can be electrically connected to and disconnected from the power supply board 35 via the power supply terminals E1 and E2 and the circuit terminals N1 and N2. The circuit-side terminal N1 is connected to the diode D1 having a rectifying action for the current flowing through the fraud detection circuit F and to the changeover switch LSW of the relay circuit 45.

  The other end of the diode D1 is connected to the standby power supply C1 and to the switch terminal 44e (detection switch 44) of the detection switch 44. In addition, the switch terminal 44 f is connected to the diode D <b> 2 having a rectifying action for the current flowing through the fraud detection circuit F and the first coil L <b> 1 of the relay circuit 45. That is, the detection switch 44 is connected to the fraud detection circuit F through the switch terminals 44e and 44f. The other end of the standby power supply C1 is grounded and connected to the circuit side terminal N2. The other end of the standby power supply C1 is connected to the diode D2 having a rectifying action for the current flowing through the fraud detection circuit F and the first coil L1 of the relay circuit 45, and is also connected to the second coil L2. . A connection terminal P3 is provided at the other end of the second coil L2. The connection terminal P3 is a terminal for connecting a reset tool for forcibly switching the contact state of the changeover switch LSW from the unauthorized detection state to the normal state.

  Further, the relay terminal P1 is connected to a diode D3 that has a rectifying action for the current flowing in the fraud detection circuit F when the first contact state is formed by the relay terminal P1 and the contact point P of the changeover switch LSW. . The other end of the diode D3 is connected to a resistor R having a predetermined resistance value (2 [kΩ] in the present embodiment) and to an output power source C2. The other end of the resistor R is connected to the signal output unit 46 and to the light emitting element of the signal output unit 46. The other end of the light emitting element is grounded and connected to the other end of the output power source C2. The relay terminal P2 is provided with a short-circuit terminal P4, and when the second contact state is formed by the relay terminal P2 and the contact point P of the changeover switch LSW, the short-circuit terminal P4 is short-circuited. Energization is not performed.

  Next, the operation of the fraud detection circuit F in the normal state and the fraud detection state will be described. In this description, it is assumed that power is supplied to the fraud detection circuit F via the power supply substrate 35.

  As shown in FIG. 6, in the fraud detection circuit F, the housing case 37 that houses the main control board 31 is mounted on the mechanism frame 25, and the fraud detection circuit 44 does not detect fraud (in a normal state). In some cases, the portions to which the switch terminals 44e and 44f (detection switch 44) are connected are short-circuited (de-energized). Further, in the normal state where the detection switch 44 does not detect fraud (the housing case 37 is not detached), the fraud detection circuit F always forms the second contact state of the contact point P of the changeover switch LSW. ing. That is, the side to which the diode D1 of the circuit side terminal N1 is not connected is short-circuited by being connected to the short-circuit terminal P4 (becomes a non-energized state). Therefore, in the fraud detection circuit F in the normal state, the circuit side terminal N1 and the diode D1 are connected, and the diode D1 and the standby power supply C1 are connected. Further, the fraud detection circuit F is in a normal state equivalent to a circuit to which the standby power supply C1 and the circuit side terminal N2 are connected. In the normal state, the standby power source C1 is connected to a power source, and can be charged by supplying power from the power source AC when the power source AC is in a power supplying state. The standby power supply C1 completes charging instantaneously when power is supplied from the power supply AC, and is ready for self-discharge. When power supply from the power supply AC is stopped, the standby power supply C1 performs self-discharge and a backup power supply. Function as.

  In the normal state of the fraud detection circuit F, when the housing case 37 that houses the main control board 31 is detached from the mechanism frame 25 and the detection switch 44 detects fraud (when it is in the fraud detection state). The portion to which the detection switch 44 is connected can be energized, and shifts from the non-energized state to the energized state. For this reason, as shown in FIG. 7, the diode D1 and the first coil L1 are electrically connected. When a current flows through the first coil L1, in the changeover switch LSW, the contact portion P forms the first contact state from the second contact state. That is, the fraud detection circuit F shifts from the second contact state that is the normal state to the first contact state that is the fraud detection state. Therefore, the circuit side terminal N1 and the signal output unit 46 are connected. Therefore, the fraud detection circuit F is in a state where power can be supplied from the power source AC to the signal output unit 46, and a fraud detection signal can be output to the hall computer HC. In the pachinko machine 10 according to the present embodiment, once the first contact state is formed after the unauthorized detection state is established, the first contact is made until the current flows through the second coil L2 until the second contact state is formed. State is to be maintained. In the present embodiment, in order to shift the contact state from the first contact state to the second contact state (shift from the unauthorized detection state to the normal state), a reset tool (not shown) is connected via the connection terminal P3. Must be used. That is, in order to shift from the unauthorized detection state to the normal state, the second coil L2 can be energized, and the contact state of the contact portion P of the changeover switch LSW can be switched to the second contact state by energization. Such a reset tool is required. Accordingly, the fraud detection circuit F cannot shift from the fraud detection state to the normal state unless the reset tool is used.

  Further, in the pachinko machine 10 of the present embodiment, power can be supplied from the standby power supply C1 to the fraud detection circuit F in a state where power cannot be supplied from the power supply AC to the fraud detection circuit F (security device S). ing. The fact that power cannot be supplied from the power supply AC means that the power supply side terminals E1 and E2 of the power supply board 35 are not connected to the circuit side terminals N1 and N2 of the fraud detection circuit F, or the power supply board 35 from the outside (power supply AC). In this state, power is not supplied.

  In a normal state in which no power is supplied from the power supply AC, the standby power source C1 configured by an electric double layer capacitor switches the changeover switch LSW when the detection switch 44 detects a fraud and enters a fraud detection state. As a backup power supply for standby. In a state in which power cannot be supplied from the power supply AC, the standby power supply C1 self-discharges longer than two days, which is a possible period of self-discharge when the backup power supply is composed of an electrolytic capacitor, according to experiments by the inventors. It has been confirmed that it will continue. Further, it has been confirmed that the standby power source C1 of this embodiment continues to self-discharge for a maximum of two months. That is, even in a non-supply state in which no power is supplied from the power source, in the normal state in the fraud detection circuit F, the changeover switch LSW can be switched by the standby power source C1 for a longer time (than two days) than before. It is like that. Further, when the standby power supply C1 is mounted on the pachinko machine 10 of the present embodiment, the housing case 37 (main control board 31) for a longer period under a situation where power is not supplied to the fraud detection circuit F. It is possible to monitor whether or not has been removed from the mechanism frame 25. Therefore, when the pachinko machine 10 is stored in the warehouse of the amusement shop before it is installed in the amusement shop, the housing case 37 (main control board 31) even when power is not supplied from the power source AC to the pachinko machine 10. It is designed to monitor the desorption state of the. Moreover, even if it is the used pachinko machine 10 removed from the amusement store for replacement of other products, it becomes possible to monitor the detachment state of the main control board 31 that has been normally manufactured. ing. Since the experiment by the inventor was performed in a specific environment, the same result is not necessarily obtained by the experiment in which the standby power supply C1 is mounted on the fraud detection circuit F of this embodiment, and an error occurs. Is.

  In the present embodiment, the standby power supply C1 continues to discharge means that the state in which power necessary for shifting the contact state of the changeover switch LSW can be constantly supplied is maintained. If the contact state of the changeover switch LSW cannot be shifted, it is considered that the discharge has been completed.

  Further, in a normal state in which no power is supplied from the power source AC, the housing case 37 that houses the main control board 31 is detached from the mechanism frame 25, and the detection switch 44 detects fraud (it is a fraud detection state). In this case, the part to which the detection switch 44 is connected can be energized, and the state shifts from the non-energized state to the energized state. Therefore, as shown in FIG. 7, the standby power supply C1 and the first coil L1 are electrically connected. When a current flows through the first coil L1, the contact state of the contact portion P of the changeover switch LSW shifts from the second contact state to the first contact state. That is, the fraud detection circuit F shifts from the second contact state that is the normal state to the first contact state that is the fraud detection state.

  A diode D1 is disposed on the signal output unit 46 side as viewed from the standby power supply C1. For this reason, even when power is supplied from the standby power source C1, the power supply from the standby power source C1 to the signal output unit 46 is not performed. For this reason, when power is not supplied from the power source AC and a fraud detection state occurs, the fraud detection signal is output from the signal output unit 46 even if the hall computer HC and the frame external terminal board 41 are connected. Not to be. However, in the relay circuit 45, once the first contact state is formed, the first contact state can be continuously maintained. Therefore, when power is next supplied from the power supply AC, the fraud detection circuit F holds the fraud detection state, so that power is supplied to the signal output unit 46 via the relay terminal P1. That is, when the first contact state is formed based on the contact state of the relay circuit 45, the fraud detection signal is output to the hall computer HC by the signal output unit 46.

  When the hall computer HC inputs various types of information including fraud detection signals (such as fraud detection signals), the hall computer HC determines that the signal input is valid on the condition that the input time is a predetermined time (16 ms in the present embodiment) or more. It is like that. The hall computer HC determines that the signal input for the predetermined time or less is invalid to prevent erroneous detection due to noise. In the fraud detection circuit F of the pachinko machine 10 according to the present embodiment, when the electric power can be supplied from the power source AC and the fraud detection state occurs, the output power source C2 is charged. Further, when power cannot be supplied from the power source AC and a fraud detection state has occurred, the output power source C2 is charged by being in a state where power can be supplied from the power source AC. Yes. The output power source C2 can supply power to the signal output unit 46 when the supply of power from the power source AC is stopped.

  When supplying power, the output power supply C2 supplies power to the signal output unit 46 via the resistor R. The maximum time during which the output power supply C2 can supply power to the signal output unit 46 can be obtained from the relationship between the electric capacity of the output power supply C2 and the resistance R of the supply destination. In the present embodiment, the maximum time during which the output power supply C2 can supply power is 20 [ ms]. That is, the output power source C2 can continue to supply power to the signal output unit 46 for a maximum of 20 [ms] after the supply of power from the power source AC is stopped. Therefore, in the fraud detection circuit F, even when the supply of power from the power source AC is stopped immediately after the fraud detection state is generated, the signal output unit 46 determines that the hall computer HC is valid for inputting signals. The signal can be continuously output for 16 [ms]. Note that when the output power source C2 is charged by the power from the power source AC, the charging is completed in an instant (as close to zero as possible), so that the fraud detection state occurs and the first contact state is formed. Then, charging is completed almost simultaneously.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) A housing case 37 that houses the main control board 31 that is one of the gaming machine components even when the pachinko machine 10 is shipped to a game shop or when the pachinko machine 10 is sold to a second-hand dealer. It is possible to detect whether or not is detached from the pachinko machine 10. Moreover, the standby power source C1 made of an electric double layer capacitor has a longer duration of electric power due to the discharge as compared with an electrolytic capacitor. For this reason, even when power is not supplied to the fraud detection circuit F such as for a long period (for example, a period longer than two days) (even when the pachinko machine 10 is not turned on), the storage case 37 (main control) is detected by the detection switch 44. The desorption state of the substrate 31) can be monitored. That is, when an abnormality is detected by the detection switch 44, the storage case 37 (main control board 31) may be detached from the pachinko machine 10, and the storage case 37 is replaced with an illegally manufactured member accordingly. There is a possibility that fraudulent acts such as Therefore, even if the pachinko machine 10 is not supplied with electric power from the power source, it is possible to monitor whether fraud has been performed for a long period of time.

  (2) In the electric double layer capacitor constituting the standby power supply C1, the voltage required for charging is lower than that of the electrolytic capacitor. For this reason, since the supplied voltage can be set to a low voltage, the supplied power can be reduced and the power consumption can be reduced. Therefore, the cost for the power supplied from the power supply AC can be reduced.

  (3) The relay circuit 45 is driven with a voltage smaller than the withstand voltage of the electric double layer capacitor. For this reason, an electric double layer capacitor can be suitably applied as the standby power source C1 serving as a backup power source. Therefore, the changeover switch LSW can be switched at a low voltage as compared with a security device (for example, Patent Document 1) in which an electrolytic capacitor is used as a backup power source.

  (4) In the fraud detection state (in an abnormal state), power is also supplied to the output power source C2 from the power source AC or standby power source C1, and the output power source C2 is charged. For this reason, when the signal output unit 46 outputs the fraud detection signal to the hall computer HC, even if the power supply is cut off due to a malfunction of the fraud detection circuit F, the signal is discharged by the output power source C2. Electric power can be supplied to the output unit 46. Therefore, it is possible to reliably output (notify) the notification information to the hall computer HC.

  (5) In addition, when an illegal act such as replacing the main control board 31 accommodated in the accommodation case 37 with an improperly manufactured main control board is performed, the person who performed the illegal act immediately after that There may be a case where the power supply path from the power source AC is cut off so that the detection signal (notification information) is not output to the hall computer HC. Even in such a case, since the fraud detection state once occurs and power is supplied to the output power source C2, the output power source C2 can be charged. Therefore, the signal output unit 46 can output the fraud detection signal to the hall computer HC (external) by the electric power discharged from the output power source C2. That is, when there is a possibility that an illegal act has been performed, the fact can be surely notified to the hall computer HC.

  (6) Once in the unauthorized detection state, in the relay circuit (latching relay circuit) 45, the changeover switch LSW continuously maintains the first contact state in the unauthorized detection state. That is, the changeover switch LSW is not switched from the unauthorized detection state to the normal state. For this reason, the relay circuit 45 remains in the fraud detection state until the next power supply even when the discharge of the standby power source C1 is terminated during the fraud detection state or when the power supply from the power source AC is cut off. Can be held. Therefore, by reflecting the detection result even after detection of the fraud detection state, it is possible to reliably notify the hall computer HC that a fraudulent act may have been performed.

In addition, you may change the said embodiment as follows.

In this case, the attachment / detachment state of the gaming machine component is detected by the configuration provided in the security device S of the present embodiment. Further, the open / closed state of the front frame 14 may be detected, and if it is in the open state, a fraud detection signal may be output to the hall computer HC. Further, in such a configuration, a fraud detection signal is output to each control board (main control board 31, display control board 32, lamp control board 33, sound control board 34, etc.) at the same time as it is output to the hall computer HC. You may make it alert | report (notify) that fraud was detected also on the apparatus 10. FIG.
