Further, on both side portions in the vertical direction, engagement protrusions 64b that protrude outward and fit with the above-described engagement holding portion 56e are formed.

  As shown in FIG. 8, the stopper member 71 is made of a resin or the like and is formed in a rectangular box shape, and is configured by combining a rectangular box-shaped outer member 80 and a rectangular box-shaped inner member 90. As shown in FIG. 10, the outer member 80 has one surface opened to have an outer opening 81, and the engaging claw 83 cut into a surface 82 facing the outer opening 81 in a tongue shape. Is formed. The engaging claw portion 83 has an inclined surface 83 a whose base end side is gently inclined outward from the surface 82, and the distal end side has an engaging surface 83 b substantially perpendicular to the surface 82. The surface 82 is formed with guide portions 82 a and 82 a that protrude outward so as to sandwich the engaging claw portion 83 and extend substantially parallel to the extending direction of the engaging claw portion 83. In addition, a mounting hole 84a is formed in a substantially central portion of each of the surfaces 84 and 84 parallel to the extending direction of the engaging claw 83, and each of the surfaces 84 and 84 is cut off from the opening 81 side. A groove 84b is formed. Similarly, a groove 85a is formed in the surface 85 on the proximal end side of the engaging claw 83, and the surface 85 is cut off from the outer opening 81 side. A groove 86a is formed by cutting the surface 86 from the outer opening 81 side.

  As shown in FIG. 11, the inner member 90 has one surface opened to form an inner opening 91. Of the side surfaces forming the inner opening 91, one of the opposing surfaces 92, 92 is formed with a mounting claw portion 92 a that protrudes outward. Further, one of the other opposing surfaces 93 has a base end portion 93a formed on the side opposite to the inner opening 91, cut into a tongue shape, and a locking projection protruding outward. A portion 93b is formed. Further, of the edge portion of the surface 94 facing the inner opening 91, the portion in contact with the surface 92 where the attachment claw portion 92 a is formed and the portion in contact with the surface 95 where the locking projection 93 is not formed are Flange portions 94a and 94b that are located in the same plane as the surface 94 and project outward are formed.

  When the inner member 90 is inserted into the outer opening 81 of the outer member 80 configured as described above from the inner opening 91 side, the flange portions 94a and 94a of the inner member 90 are inserted into the groove portion 84b of the outer member 80. The flange portion 94b is combined so as to close the outer opening 81a side of the groove portion 86a, and the attachment claw portion 92a engages with the attachment hole 84a so that the inner member 90 is fixed to the outer member 80, thereby stopping the stopper member 71. Is assembled. At this time, the locking projection 93b of the inner member 90 protrudes outward from the groove 85a of the outer member 80.

  The stopper member 71 is used by being inserted into the lid side engaging portion 64 as shown in FIGS. First, in order to restrict the sliding movement of the case lid member 60 attached to the case main body member 50 in the right direction (this is referred to as “locking state”), as shown in FIG. The lid is such that the engaging claw 83 faces downward and the inclined surface 83a of the engaging claw 83 is located to the left (the direction in which the case claw member 60 is slid and moved when attached to the case body member 50). The stopper member 71 is inserted into the side engaging portion 64 (the state of the stopper member 71 is referred to as “locked state”). When the stopper member 71 is inserted into the lid side engaging portion 64, the locking projection 93b of the stopper member 71 is pressed against the inner wall of the lid side engaging portion 64 and elastically biased. Even if the opening of the lid side engaging portion 64 is directed downward, the stopper member 71 does not easily fall off.

  In this state, when the locking projection 62 of the case lid member 60 is inserted into the lid member mounting groove 54 of the case body member 50, the engaging claw 83 of the stopper member 71 is positioned in the claw retracting recess 56f. The engaging claw portion 83 is not pushed upward, and as a result, the lid side engaging portion 64 is also not pushed up. When the case lid member 60 is slid leftward with respect to the case body member 50, the engaging claw portion 83 of the stopper member 71 is formed on the right end side of the claw waiting recess 56f along the inclined surface 83a. The locking claw 83 moves to the left while being pushed up by the inclined surface. At this time, the engaging protrusion 64b formed on the lid side engaging portion 64 is inserted into the engaging holding portion 56e formed on the main body side engaging portion 56 from the right end portion at the same time. Even if 83 is pushed up, the lid side engaging portion 64 is not pushed up.

  Then, when the lid side engaging portion 64 and the main body side engaging portion 56 are overlapped, the positions of the engaging claw portion 83 and the engaging concave portion 56c coincide with each other, and the pushed engaging claw portion 83 is The engaging recess 56c is elastically engaged, the engaging recess 56c and the engaging claw 83 are engaged, and the guide portions 82a and 82a of the stopper member 71 are engaged with the engaging grooves 56d and 56d of the main body side engaging portion 56. Further, the engagement protrusion 64b and the engagement holding portion 56e are fitted, and the main body side engagement portion 56 and the lid side engagement portion 64 are engaged. In this state, even if the case lid member 60 is slid to the right, the engagement surface 83b of the engagement claw 83 is engaged with the engagement recess 56c, and this engagement surface 83b is engaged. Since it extends along the wall of the recessed portion 56, the engaging claw portion 83 is not pushed upward, and the engaging protrusion 64b and the engaging holding portion 56e are fitted, so that the lid side engagement is achieved. The mating portion 64 cannot be pulled away from the main body side engaging portion 56, and the engaging claw 83 is not detached from the engaging recess 56c. Therefore, the main body side engaging portion 56 and the lid side engaging portion 64 are fixed, and the case lid member 60 can be fixedly held (locked) with respect to the case main body member 50.

  On the other hand, as shown in FIG. 13, when the engaging claw 83 is inserted into the lid side engaging part 64 so as to be positioned in the lid side engaging part 64 (the engaging claw part 83 is located upward). When the main body side engaging portion 56 and the lid side engaging portion 64 are not engaged with each other, the case main body member 50 is inserted. On the other hand, the case lid member 60 can be slid rightward (this state is referred to as a “released state”).

  In this way, when the case lid member 60 is slid relative to the case body member 50 so that the lid side engaging portion 64 overlaps the body side engaging portion 56, the engagement claw portion 83 and the engaging claw portion 83 are engaged. The main body side engaging portion 56 and the lid side engaging portion 64 are latched and held by engaging the mating concave portion 56c, and the sliding movement of the case lid member 60 in the right direction relative to the case main body member 50 is restricted. Therefore, the state where the case lid member 60 is attached to the case body member 50, that is, the locked state is maintained. Thereby, the main body side engaging portion 56 and the lid side engaging portion 64 can be easily coupled via the stopper member 71, and the case main body member 50 and the case lid member 60 are easily coupled and held in the closed state. can do.

  If the case main body member 50 and the case lid member 60 are coupled and held in a closed state by the unauthorized opening prevention mechanism 70, the engagement with the stopper member 71 engaged with the main body side engaging portion 56 is released. In order to open the main board case 100 (the main board assembly 30), it is necessary to cut the lid side connecting portion 66 and separate the lid side engaging portion 64 from the case lid member 60. . Therefore, after the main board case 100 is opened, the cutting trace of the lid side connecting portion 66 remains clearly, so that unauthorized opening can be detected at an early stage and fraud can be effectively suppressed. Further, in order to change the unauthorized opening prevention mechanism 70 from the released state to the locked state, the direction of the engaging claw 83 of the stopper member 71 is changed with respect to the lid side engaging portion 64 (the lid side engagement in the unlocked state). It is only necessary to take out the stopper member 71 inserted in the portion 64 and replace it in the locked state), so that the operation is very easy.

  In the present embodiment, the unauthorized opening prevention mechanism 70 has four sets of the main body side engaging portion 56, the lid side engaging portion 64, and the stopper member 71. In order to be coupled and held by the unauthorized opening prevention mechanism 70, any one stopper member 71 is inserted in a locked state, that is, with the engaging claw portion 83 protruding downward with respect to the lid side engaging portion 64. It should be. Therefore, for example, even if the main board case 100 in the closed state (locked state) is opened in order to inspect the main control board 31, the closed state (locked state) is used by using another set of the unauthorized opening prevention mechanism 70. ). Moreover, it can be confirmed how many times the main board case 100 is opened by the number of the lid-side engaging portions 64 cut out.

  At this time, by forming the outer member 80 and the inner member 90 constituting the stopper member 71 with resins of different colors (for example, the outer member 80 is white and the inner member 90 is red), the case lid member 60 is formed. Is formed of a transparent resin, the inserted state of the stopper member 71 is the locked state (the inner member 90 is on the upper side and the red color can be seen through the lid side engaging portion 64), or the upper side is directed upward. Whether the outer member 80 is in the unlocked state (the outer member 80 is on the upper side and the white color can be seen through the lid side engaging portion 64) can be easily identified. Alternatively, by displaying a character such as “lock” on the surface 94 of the inner member 90, the character can be confirmed through the transparent lid side engaging portion 64 in the locked state, and the locked state is identified. can do.

  Further, as described above, a transparent resin material is used as the material of the main substrate case 100 (the case body member 50 and the case lid member 60). Among them, it is preferable to use an ABS resin. As a result, when the cutting operation is performed on the member as described above, the butadiene, which is a component of the ABS resin, has a rubber property, and the member is easily whitened without being cracked. The effect is easy. Further, even if the main board case 100 is forcibly opened, an effect is obtained in which the member is similarly whitened and the trace is easily left clearly. At this time, as described above, the periphery of the opening of the lid side engaging portion 64 is covered with the engaging wall portion 56b of the main body side engaging portion 56, and the engaging claw portion 83 of the stopper member 71 is on the main body side. Since it is sandwiched between the guide portions 82a and 82a inserted into the engaging grooves 56d and 56d of the engaging portion 56, it is difficult to operate the engaging claw portion 83 when trying to pry open the locked state. The lid side connecting portion 66 is configured to easily whiten when it is forced to operate.

  Thus, the unauthorized opening prevention mechanism 70 holds the main board case 100 in the closed state by engaging the engaging claw 83 of the stopper member 71 with the engaging recess 56c of the main body side engaging portion 56. In order to ensure that the main board case 100 is in the closed state, it is necessary to ensure that the stopper member 71 is formed according to a predetermined standard (shape, dimensions, etc.). Therefore, in this embodiment, the IC tag 210 is enclosed in the stopper member 71, and the stopper member 71 in which the IC tag 210 is enclosed is configured to be a regular part. Here, the IC tag is a device that can read and write information from and to a memory of the IC tag without contact by irradiating an electromagnetic wave from a device called a reader / writer. The IC tag 210 is attached to the inner peripheral surface side of the inner member 90 constituting the stopper member 71, for example, as shown in FIG.

  As described above, since the stopper member 71 is configured to fit and assemble the two members of the outer member 80 and the inner member 90, the IC tag 210 is attached to the inner surface side of the inner member 90. Is easy. Further, the inner member 90 is fitted and assembled to the outer member 80, and these are fused or bonded together, thereby enclosing the IC tag 210 in the stopper member 71 and making it difficult to take out the IC tag 210 from the outside. It is also easy to do.

  Now, a stopper member check system 200 for checking whether or not the stopper member 71 attached to the main board case 100 is correct will be described with reference to FIGS. FIG. 14 is a perspective view showing the stopper member check system 200, and FIG. 15 is a block diagram showing a functional configuration of the stopper member check system 200.

  The terminal device 220 constituting the stopper member check device 200 includes a housing 221, an antenna 222, a display unit 223, and an input unit 224. The housing 221 includes a reader / writer unit 225 and a control unit 226. ing. The reader / writer unit 225 irradiates the IC tag 210 built in the stopper member 71 with electromagnetic waves from the antenna 222 to read / write information from / to the IC tag 210, and is controlled by the control unit 226.

  Therefore, as shown in FIG. 14, the terminal device 220 is arranged behind the pachinko machine PM, and an instruction to read information from the IC tag 210 is given from the input unit 224. Then, the control part 223 controls the reader part 225, reads the information of the IC tag 210, and displays the read result on the display part 223. At this time, even if a plurality of stopper members 71 are attached to the main board case 100, the reader / writer unit 225 can simultaneously read the information of each of the IC tags 210 built in these stopper members 71. Information is displayed on the display unit 223. As described above, since the number of the stopper members 71 can be determined by visually observing the number of the lid-side engaging portions 64, the information (number) of the IC tag displayed on the display portion 223 and the lid side visually confirmed. By comparing the number of the engaging portions 64 (or the stopper member 71 inserted therein), it can be confirmed whether or not the regular stopper member 71 is used.

  It is possible to identify each of the stopper members 71 by storing identification information composed of unique numerical information or the like in each IC tag 210. For example, the identification information stored in the IC tag 210 enclosed in the stopper member 71 to be checked is stored in the terminal device 220 and read from the IC tag 210 of the stopper member 71 attached to the pachinko machine PM. By comparing with the identification information thus made, it is possible to confirm whether or not the stopper member 71 registered in advance is being used.

  The main effects achieved in the embodiment of the present invention described above can be summarized as follows. By enclosing the IC tag 210 in the stopper member 71, the terminal device 220 reads out this information, so that the regular stopper member 71 is used. (That is, whether or not the stopper member 71 whose quality is guaranteed is used) can be inspected. Thereby, it can be confirmed that the unauthorized opening prevention mechanism 70 functions normally.

  In the above embodiment, the case where the IC tag 210 is used for the stopper member 71 used in the unauthorized opening prevention mechanism 70 for preventing the unauthorized opening of the main board case 100 of the pachinko machine PM has been described. Implementation is not limited to this stopper member 71, and any other member that can be attached to and detached from the pachinko machine PM can be used in the same manner.
