Description

  The present invention relates to a control device used for various devices including a gaming machine such as a pachinko machine and a slot machine, and more specifically, a control device for a gaming machine capable of effectively preventing fraud. It is about.

  As a control device for a pachinko machine, a device in which a control element such as an LSI or a ROM for controlling the operation content is covered with a divided storage case is known. In such a control device, an illegal act may be performed in which the storage case is opened and a control element such as an LSI or a ROM is replaced with a counterfeited one. Therefore, as a control device capable of preventing such illegal acts, an IC tag storing unique identification information is attached to the surface of the storage case, and an ID reader is installed in the vicinity of the IC tag. A device in which identification information of an IC tag is read (confirmed) at regular intervals by a reading device has been devised (see, for example, Patent Document 1).

JP 2000-288218 A

  However, since the control device disclosed in Patent Document 1 can freely move the ID reader, the storage case can be opened and closed without changing the relative position between the ID reader and the IC tag. Therefore, there is a possibility that the storage case is opened and a control element such as an LSI or a ROM is replaced.

  Therefore, the applicants put the IC tag on one side of the split storage case to prevent the IC tag from being removed without changing the relative position between the IC tag and the device that reads the information on the IC. An antenna that does not perform its function of transmitting and receiving signals when it is attached and peeled off (an antenna that transmits and receives signals wirelessly with an IC tag) spans all parts of the split storage case. A control device was invented so as to cover it (Japanese Patent Application 2002-346385).

  In addition, the applicants attach the IC tag to one side of the split-type storage case, and, as a monitoring device, an antenna that can transmit and receive with the IC tag (an antenna that transmits and receives wirelessly with the IC tag) faces the IC tag. In order to install the antenna at the position, a technique has been proposed in which the belt member laid with the antenna wiring is wound around the split storage case of the control device (Japanese Patent Application No. 2003-311884).

  However, the control device according to Japanese Patent Application No. 2002-346385 must peel off the antenna when opening the storage case for repair / maintenance of the built-in board or checking of the control element. Moreover, since the antenna will be self-destructed if it is peeled off, a new antenna must be pasted and re-wired after repair / maintenance of the substrate and check of the control element. Therefore, the work of repairing / maintaining the substrate and checking the control element is troublesome.

  On the other hand, according to the method of Japanese Patent Application No. 2003-311884, if the wiring of the antenna wound around the divided storage case of the control device is not cut, the divided storage case cannot be opened, and the wiring of the antenna Since the communication between the IC tag and the antenna is cut off when the connection is cut off, it becomes possible to monitor fraudulent acts on the control device very efficiently. However, in the technology of Japanese Patent Application No. 2003-311884, the antenna wiring laid on the belt member is only covered with a thin film made of resin constituting the belt member. There can be a situation where the wiring is damaged and the monitoring device fails to function. In addition, when the belt member is wound around the outer periphery of the control device, an excessive stress is applied to the wiring of the antenna due to the bending of the inner portion of the belt member (the portion on the contact side with the control device), There may also be a situation where the antenna wiring is damaged. This tendency becomes more prominent when the monitoring device is repeatedly attached to the control device over a long period of time.

  The object of the present invention is to solve the problems of the conventional control device, to effectively prevent a fraud in which a storage case of the control device or the like is opened to replace the control element, and for a long period of time. It is to provide a fraud monitoring unit that is not damaged even if it is used repeatedly.

And a housing capable of engaging the tip of the belt member with the base end of the belt member fixed.

  The structure of the invention described in claim 2 is that, in the invention described in claim 1, the protective cover is provided with a guide groove for slidingly inserting the inner.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, when the insertion of the inner into the protective cover is completed, the tip of the guide groove of the protective cover The tip of the inner part is separated by a predetermined length, and the inner part is slidable in the protective cover when the protective cover is bent.

  According to a fourth aspect of the present invention, there is provided a control device in which a control element for controlling the operation content of a device that performs a predetermined operation is stored in a state where the control element is cut off from the outside by a storage case. The fraud monitoring unit according to any one of Items 1 to 3, wherein the IC tag is attached to the storage case, the belt member is wound around the outer periphery of the storage case without slack, and the tip of the belt member is engaged with the housing. The antenna mounted in the state and accommodated in the housing of the mounted fraud monitoring unit is capable of RF communication with the IC tag.

  According to a fifth aspect of the present invention, there is provided a gaming machine comprising the control device according to the fourth aspect.

  According to the fraud monitoring unit described in claim 1, the IC tag is fixed to the storage case of the control device, and the IC tag and the antenna face each other (so that non-contact ID communication can be performed. I) It is possible to monitor the unauthorized opening of the control device by simply winding the belt member around the storage case of the control device. Further, it can be very easily attached to a control device of a gaming machine already installed in a game hall, a different type of control device manufactured by each manufacturer, or the like. In addition, in the fraud monitoring unit described in claim 1, the belt member has a two-layer structure of the inner and the protective cover, and the portion where the lead wire (antenna wiring) is laid is covered with the protective cover. Therefore, damage to the lead wire can be efficiently prevented over a long period.

  According to the fraud monitoring unit described in the second aspect, the lead wire laid on the inner can be covered with the protective cover very easily only by sliding the inner into the protective cover along the guide groove.

  According to the fraud monitoring unit described in claim 3, when the belt member is wound around the outer periphery of the device during monitoring of a predetermined device, the tip of the inner slides appropriately within the protective cover, Since an excessive stress is not applied to the lead wire, the lead wire is not damaged even when the attachment and removal are repeated.

  In the control device according to the fourth aspect, when the storage case is illegally opened (that is, when the fraud monitoring unit is peeled off), the IC tag and the antenna cannot be transmitted / received and are illegally opened. The situation can be detected immediately (in real time). Therefore, unauthorized acts such as unauthorized replacement of a control element such as an LSI or unauthorized modification can be effectively prevented.

  In the gaming machine according to the fifth aspect, when the storage case of the control device is illegally opened, the situation can be immediately detected by the IC tag and the antenna. It is possible to effectively prevent unauthorized acts such as unauthorized replacement and unauthorized modification.

When the IC tag 26 transmits the reflected wave, the R / W unit 38 receives the reflected wave (RF reception) by the antenna 32 in the monitoring unit 74. When the R / W unit 38 confirms that the identification code included in the reflected wave is registered, the R / W unit 38 immediately transmits the ringing wave again to perform the monitoring operation in a short period (about several tens of ms). Repeatedly.

  On the other hand, when the R / W unit 38 does not receive the reflected wave within a predetermined time (for example, 50 ms) after transmitting the ringing wave (that is, when the control device 1 is illegally released), Judgment is made and the fact that an abnormality has been detected is stored in the EEPROM 52, and a predetermined abnormality detection signal is output to the outside to alert the pachinko hall clerk and manager.

  Therefore, the monitoring unit 74 is forcibly moved so that the distance between the antenna 32 and the IC tag 26 exceeds the output range of the ringing wave output from the antenna 32 and the output range of the reflected wave output from the IC tag 26. In this case, since the antenna 32 and the IC tag 26 cannot transmit / receive the ringing wave / reflected wave, the R / W unit 38 stores the fact that the abnormality has been detected in the EEPROM 52 and a predetermined abnormality. Output the detection signal to the outside.

  Further, when the monitoring unit 74 is peeled off or the band cover 80 is cut (when the lead wire 110 is cut), the R / W unit 38 communicates with the IC tag 26 via the antenna 32. Therefore, the fact that an abnormality has been detected is stored in the EEPROM 52 and a predetermined abnormality detection signal is output to the outside.

6). Advantages of Unauthorized Monitoring Unit, Control Device, and Game Machine of Embodiment The unauthorized monitoring unit (IC tag 26, monitoring unit 74, and R / W unit 38) of the embodiment is a monitoring device as described above. The unit 38 includes a long band inner 105 (inner) in which the lead wires 110 are laid in a folded shape along the longitudinal direction, and a band cover 80 (protective cover) covering the lead wires 110 laid on the band inner 105. A belt member and a housing H provided with an antenna 32 and capable of engaging the distal end of the band cover 80 with the base end of the band cover 80 fixed thereto. Since the lead wire 110 laying portion is covered with the band cover 80, the lead wire 110 is Damage to the lead wire 110 can be effectively prevented over a long period of time.

Further, in the fraud monitoring unit 74, since the band cover 80 is provided with a guide groove 112 for slidingly inserting the band inner 105, the band inner 105 is slid into the band cover 80 along the guide groove 112. The lead wire 110 laid on the band inner 110 can be covered with the band cover 80 very easily.

  Further, in the fraud monitoring unit 74, since the length of the guide groove 112 of the band cover 80 is longer than the insertion portion 70 of the band inner 105, the insertion of the band inner 105 into the band cover 80 is completed. When the band cover 80 is bent, the tip of the guide groove 112 of the band cover 80 and the tip of the band inner 105 are separated by a predetermined length (about 1 cm). Inside is slidable. Therefore, when the outer periphery of the storage case C of the control device 1 is wound around, the tip of the band inner 105 is appropriately slid within the band cover 80, thereby causing an excessive stress on the lead wire 110. Therefore, the lead wire 110 is not damaged even when the attachment and removal are repeated.

  On the other hand, as described above, the control device 1 causes the fraud monitoring unit to attach the IC tag 26 to the storage case C and wind the band inner 105 and the band cover 80, which are belt members, on the outer periphery of the storage case C without slack. The band cover 80 is attached with the tip of the band cover 80 engaged with the housing H by the operation of the knob 96, which is a detachable knob, and the antenna 32 installed in the housing H of the attached fraud monitoring unit is connected to the IC tag. 26 is in a state in which non-contact ID communication can be performed (that is, in a state of facing the IC tag 26 with a predetermined distance (about 3.0 mm or less) capable of wireless communication). Therefore, when the storage case C is illegally opened (that is, the monitoring unit 74 is peeled off or the band cover 80 of the monitoring unit 74 is removed). If you or disconnected) includes an IC tag 26 and the antenna 32 becomes impossible transceiver can immediately (in real time) detect the fraudulently opened situation. Therefore, unauthorized actions such as unauthorized replacement of the control elements such as the LSI 25 and unauthorized modification can be effectively prevented.

  On the other hand, the pachinko machine 1 includes the control device 1 with the fraud monitoring unit mounted thereon as described above, so that when the storage case C of the control device 1 is illegally opened, the IC tag 26 and the antenna 32 Therefore, such a situation can be detected immediately, so that illegal acts such as unauthorized replacement of a control element such as an LSI or unauthorized modification can be effectively prevented.
