In the liquid crystal panel 22, for example, a payout medal number display unit 22a, a credit number display unit 22b for displaying the number of payout medals when BB, RB, a small role, etc. are won, the number of games played in the BB mode or the RB mode. Is displayed, and a payout number display portion 22d for displaying the payout number of medals is provided, and information corresponding to each model of the slot machine 10 is displayed.

  As shown in FIG. 2, a main board (circuit board) 24 as a main control unit for generating a basic operation of the game in the slot machine 10 and controlling reel rotation and the like is provided inside the housing 11. It is arranged. The main board 24 is housed in a main board housing case (circuit board housing case) 30. The reel unit 25 is attached to a support frame 26, and the support frame 26 is detachably attached inside the housing 11. For this reason, the reel unit 25 can be replaced together with the support frame 26.

  As shown in FIGS. 3 to 4, the main substrate storage case 30 includes a case base 31 and a case lid 32, and the case base 31 is attached to the back side inner wall inside the housing 11. The case base 31 houses a main board 24 on which various circuit components such as a ROM 24b storing a game operation program of the CPU 24a and the slot machine 10 are mounted. By attaching the case lid 32 to the case base 31, the main substrate 24 is sealed in the main substrate storage case 30 so as not to be exposed to the outside.

  The case base 31 has six screwed portions (connecting portions) 34 into which screws (connecting members) 33 are screwed, along the edges of both end portions in the longitudinal direction. The case lid 32 is formed with six screw insertion portions (connection portions) 35 through which screws 33 are inserted, along the edges of both end portions in the longitudinal direction. The screw 33 is a one-way screw that can be rotated (fastened) only in the tightening direction, and one screw 33 is used for each screw insertion portion 35. When the screw 33 is screwed into the screw threaded portion 34 from the screw insertion portion 35 side, the head (fastening operation portion) 33b (see FIG. 5) of the screw 33 that is removed when the main substrate storage case 30 is tampered with is opened. One caulking member (cover member) 36 fixed to the screw insertion portion 35 so as to cover the screw 33 is used for each screw 33.

The RFID tag 37 includes an IC chip 37a and a transmission / reception antenna 37b formed by winding a copper wire in a coil shape. Since the RFID tag 37 does not have a built-in power supply, the transmission / reception antenna 37b receives power from electromagnetic waves received from a dedicated RFID reader / writer 40 (hereinafter, “reader / writer” is described as “R / W”) by electromagnetic induction. And the IC chip 37a is operated using this as a power source.

  The IC chip 37a stores a seal code (data) C and performs wireless communication with the RFID R / W 40. As the sealing code C, for example, a code for each model of the slot machine 10 is used, but an arbitrary code set appropriately in the game hall is desirable. For this reason, although not shown in detail in the IC chip 37a, the seal code C is stored in the RFID R / W 40 via the memory (for example, FRAM (Ferroelectric Random Access Memory)) and the transmitting / receiving antenna 37b. And a communication circuit for outputting data.

  The RFID tag 37 and the RFID R / W 40 are well-known devices that wirelessly read and write information without contact, and are currently used in, for example, railway and bus tickets, highway usage money collection systems, and the like. It has been put into practical use.

  As shown in FIG. 5, the screw 33 has a head portion 33b formed at one end of the shaft portion 33a. On the upper surface of the head portion 33b, an engagement groove in which a tool such as a screwdriver can be engaged only in one direction. 33c is formed. As shown in the figure, the engagement groove 33c is formed by, for example, a vertical cut and an oblique cut. The tool has a strong engagement force with the vertically cut portion, so that the screw 33 can be rotated in that direction, but the engagement force with the oppositely cut portion is weak. , You can not rotate in that direction.

  A screw hole 34 a into which the shaft portion 33 a of the screw 33 is screwed is formed in the screw screw portion 34. The screw insertion portion 35 is formed with a recess 35c surrounded by an inner side surface 35a and an inner bottom surface 35b. The inner bottom surface 35b is formed with an insertion hole 35d through which the shaft portion 33a of the screw 33 is inserted. All of the shaft 33a of the screw 33 is inserted into the insertion hole 35d and screwed into the screw hole 34a so that the surface of the head 33b on which the shaft 33a is formed contacts the inner bottom surface 35b of the screw insertion part 35. By tightening the screw 33, the case lid 32 is connected to the case base 31, and the main substrate 24 is sealed inside the main substrate storage case 30.

  A fitting groove 35e that is recessed so that the retaining portion 36a of the caulking member 36 is fitted is formed on the inner side surface 35a of the screw insertion portion 35. The retaining portion 36a has a tubular shape in which both end portions of the belt are connected, one side edge portion is connected to the lower end portion of the side circumferential surface of the disk-shaped caulking member 36, and the other side edge portion. Is in a state of being opened away from the upper end portion of the side circumferential surface of the caulking member 36.

  FIG. 6 shows a state in which the caulking member 36 is fitted into the concave portion 35 c of the screw insertion portion 35 so as to cover the head portion 33 b of the screw 33 that is fastened. When the caulking member 36 is inserted into the recess 35c with the case lid 32 attached to the case base 31 with the screw 33 (FIG. 6A), the retaining portion 36a comes into contact with the inner side surface 35a and elastically deforms to the inner side. (FIG. 6B). When the caulking member 36 is pushed further downward, the retaining portion 36a is fitted into the fitting groove 35e, and the retaining portion 36a is brought into the original open state in the fitting groove 35e by the restoring force (FIG. 6C). . Once the caulking member 36 is fitted into the recess 35c, the retaining portion 36a cannot be operated from the outside. Further, the retaining portion 36a functions as a stopper that prevents the caulking member 36 from being pulled out upward and cannot be separated from the screw insertion portion 35. Therefore, the case lid 32 connected to the case base 31 cannot be removed.

  As a result, the main substrate storage case 30 is crimped and cannot be opened unless the crimping member 36 is destroyed. When the caulking member 36 is destroyed, at least a part of the RFID tag 37 enclosed therein is destroyed, so that the sealing code C stored in the IC chip 37a cannot be read. In this manner, the caulking member 36 including the RFID tag 37 can be sealed so as to reliably leave a trace when the main substrate storage case 30 is tampered with.

  The operation of the slot machine 10 configured as described above will be described. When installing the slot machine 10 in the amusement hall, the installer operates the screw 33 of the main board storage case 30 disposed in the housing 11 with a tool to seal the main board 24 therein. Thereafter, the caulking member 36 is fitted into the screw insertion portion 35 through which the screw 33 is inserted so as to cover the head portion 33b of the screw 33 to be tightened. Then, the installer operates the RFID R / W 40 and registers (writes) the seal code C in the RFID tags 37 of all the caulking members 36 by wireless communication using a data signal of a specific frequency and a security approval signal. Sealing of the main board storage case 30 is completed. Note that the registration operation of the sealing code C may be performed in advance before the main substrate storage case 30 is sealed.

  After the slot machine 10 is installed in the game hall, the game hall manager authenticates the seal code C registered in the RFID tag 37 as needed. The administrator operates the RFID R / W 40 to authenticate the seal codes C registered in the RFID tags 37 of all the caulking members 36 by wireless communication at a specific frequency. If the seal code C read out in this way is correct, it can be determined that the main substrate storage case 30 has not been tampered with. On the other hand, if the correct seal code C cannot be read, it can be determined that the main board storage case 30 has been tampered with.

  Further, the administrator can appropriately rewrite and change the sealing code C registered in the RFID tag 37. In addition, since communication between the RFID tag 37 and the RFID R / W 40 is performed wirelessly in a non-contact manner, the seal code C can be read and written in a game-ready state installed in the game room without opening the door of the slot machine 10. It can be performed. Further, it is possible to simultaneously access a plurality of RFID tags 37 and read / write all the sealing codes C at once. In this way, it is possible to easily determine whether or not the main board storage case 30 has been tampered with, and it is possible to prevent an unauthorized third party from committing the main board 24.

  In the above embodiment, the retaining portion 36a is provided so that the crimping member 36 cannot be separated from the screw insertion portion 35. However, the present invention is not limited to this, and the retaining portion 36a may not be provided. For example, as shown in FIG. 7A, a portion of the inner side surface 35a of the screw insertion portion 35 that is located above the fitting groove 35e is cut out obliquely, and the inner diameter of this portion increases as it goes upward. To. When a disc-shaped caulking member 36 having a diameter slightly larger than the minimum inner diameter of this portion is inserted into the recess 35c, the diagonally cut portion of the screw insertion portion 35 is elastically deformed (FIG. 7B). When the caulking member 36 is further pushed downward, the vicinity of the end portion is fitted into the fitting groove 35e (FIG. 7C).

  Since the caulking member 36 fitted in this way cannot be pulled out upward, if the main board storage case 30 is forcibly opened, at least a part of the internal RFID tag 37 is destroyed. The caulking member 36 may be welded or bonded to the screw insertion portion 35 after the caulking member 36 is fitted in the fitting groove 35e.

  In the above embodiment, six screw screw portions 34 and six screw insertion portions 35 are formed along the edges of both ends in the longitudinal direction of the main substrate storage case 30. However, the present invention is not limited to this, and screw screw connections The positions and the number of the portions 34 and the screw insertion portions 35 may be set as appropriate. For example, as shown in FIG. 8, a screw threaded portion 34 and a screw insertion portion 35 are formed only along the edge of one end portion in the longitudinal direction, and a case base 31 and a case lid 32 are formed at the other end portion in the longitudinal direction. You may provide the hinge 38 which connects and rotates.

  In the above embodiment, the one-way screw that can be rotated only in one direction is used as the screw 33 in order to seal the main board storage case 30 more securely. However, the screw 33 is not limited to this and the screw 33 rotates in both directions. An ordinary screw that can be operated may be used as long as the case base 31 and the case lid 32 can be connected to each other.

  In the above embodiment, the screw threaded portion 34 is formed in the case base 31 and the screw insertion portion 35 is formed in the case lid 32. However, the present invention is not limited to this, and conversely, the screw insertion portion 35 is formed in the case base 31. It is also possible to form a screw threaded portion 34 in the case lid 32.

  In the above embodiment, the case base 31 and the case lid 32 are connected using the screw 33. However, the present invention is not limited to this, and a connecting member such as a pin may be used instead of the screw 33. In order to seal 30, the fastening operation portion operated when the connection member is removed from the connection portion may be covered with a caulking member provided with the RFID tag 37 so that it cannot be operated from the outside.

  Moreover, in the said embodiment, although the crimping member was made into the disk-shaped chip shape, it is not restricted to this, What is necessary is just a shape which can cover a fastening operation part at the minimum.

  In the above embodiment, the slot machine 10 including the main board storage case 30 has been described. However, the slot machine 10 is not limited to the slot machine 10, and the main board storage case 30 is mounted on a gaming machine such as a pachinko machine or other devices. You may make it do.
