Description

  The present invention relates to a case sealing structure for a case such as a board case for accommodating a control board of a gaming machine, and more particularly to a case sealing structure using an IC tag sealing seal.

  In gaming machines such as pachinko machines and slot machines, a control board for controlling the operation of the gaming machine is provided. For example, in a pachinko machine, a game board or the like is mounted on a storage frame on the back side of the front frame that is assembled so as to be openable and closable with respect to an outer frame, and a control board is attached to the game board. Similarly, in the slot machine, a control board is attached to the back side of the front mask or the inside of the cabinet. These control boards are boards that control the operation of pachinko machines or slot machines, such as prize ball or medal payout control, opening / closing control of electric objects, reel rotation control, symbol combination occurrence probability control, etc. ROM in which the control software is recorded is mounted and has a role as a central control device for controlling the operation of the gaming machine (see, for example, Patent Document 1).

  The control board having the role as such a central control device is accommodated in the board case as a countermeasure against unauthorized modification such as replacement with a counterfeit ROM, and unauthorized opening prevention means for preventing the board case from being opened illegally. It is known to provide As the unauthorized opening prevention means, for example, when the control board is housed in a board case made up of a case body member and a case lid member, and the case lid member is attached to the case body member in a closed state, the case body member side Using a tool such as a nipper to connect the engaging portion formed on the case and the engaging portion formed on the case lid member side, and connecting the case lid member (or case main body member) and the engaging portion. Various so-called caulking structures that make the case body member and the case lid member inseparable from each other unless otherwise separated have been proposed and put into practical use.

  It is also known to seal a board case inside using an IC tag sealing sticker having a wirelessly readable IC tag storing unique information of a gaming machine, identification information of a control board, and the like (for example, , See Patent Document 2). When the IC tag seal seal is used in this way, not only the control board is placed in the substrate case and closed and held by the caulking structure, but also the IC tag seal seal is used for more reliable measures against unauthorized opening. Further, there is an advantage that the control board can be identified by reading information stored in the IC tag from the outside.

First, when the case lid member 60 is closed so as to cover the case main body member 50 from behind at a position slightly shifted to the left with respect to the case main body member 50, the lid side sealing portion 160 is formed with respect to the main body side sealing portion 150. 6 moves forward as indicated by an arrow A, and as shown in FIG. 13, the lid-side sealing portion 160 overlaps the main-body-side sealing portion 150 in a state of being slightly shifted to the left. At this time, the slide guide protrusions 163 and 163 of the lid side seal portion 160 are fitted into the upper and lower slide guide grooves 153 and 153 of the main body side seal portion 150 so that the slide guide protrusions 163 and 163 are slidably moved to the left and right.

  From this state, the case lid member 60 is slid rightward with respect to the case main body member 50. As a result, as shown by an arrow B in FIG. As shown in FIG. 14, it is slid rightward and positioned at a position that exactly overlaps the main-body-side sealing portion 150 (a position at which the left end side faces are aligned). In this state, the case main body member 50 and the case lid member 60 are coupled together by the fraud prevention mechanism. However, the case sealing portion 100 is surrounded by the main body side sealing portion 150 and the lid side sealing portion 160 at the left end portion. An open sealing space 110 (see FIG. 17 and the like) is formed.

  Next, a seal for covering the IC tag seal seal 185 affixed to the pedestal portion 152 and sealing the IC tag seal seal 185 when the case lid member 60 is opened in the seal space 110 thus formed. The breaking member 120 is inserted. The seal breaking member 120 includes a seal cover member 170 shown in FIG. 16 and an engagement holding member 175 shown in FIG. 20, and the seal cover member 170 is first inserted into the sealing space 110 as described below. Then, the engagement holding member 175 is inserted.

  As shown in FIG. 16, the seal cover member 170 includes a rectangular plate-shaped cover member body 171 and a pair of holding protrusions that protrude forward and downward near the right end of the front surface (back surface) of the cover member body 171. 172, 172 and a rupture protrusion 173 formed to project forward in the vertical center of the right end of the front surface (back surface) of the cover member body 171, and the right end of the rear surface (front surface) of the cover member body 171. A pair of upper and lower engaging recesses 174 and 174 are formed in the vicinity. The rupture protrusion 173 has a tip 173a formed in an acute angle shape. As will be described later, when the case lid member 60 is removed, the rupture projection 173 plays the role of a blade that tears the IC tag seal seal 185 by the tip 173a.

  The seal cover member 170 is inserted into the sealing space 110 from the left end opening as indicated by an arrow C in FIGS. 15 and 17A. As shown in FIG. 17B, when the seal cover member 170 is inserted to the back (right back) of the sealing space 110, the pair of upper and lower holding protrusions 172 and 172 form a pair of upper and lower holding openings of the lid-side sealing portion 160. 163c and 163c. In this state, the seal cover member 170 is moved to the front side (in the direction perpendicular to the insertion movement direction indicated by the arrow C at the back of the sealing space 110) as indicated by the arrow D in FIG. As shown by (C), the holding projection 172 is inserted into the holding opening 163c. As a result, the front surface (back surface) of the seal cover member 170 covers the IC tag seal seal 185 attached to the pedestal portion 152 and is held so as not to come out.

  FIG. 17 is a cross-sectional view of the case sealing portion 100 taken along arrows XVII-XVII in FIG. 14 and shows a cross section of a portion near the upper end of the sealing space 110. The central portion of the sealing space 110 is indicated by the arrow XVIII. It is shown in FIG. 18 along -XVIII. In this portion, the fracture protrusion 173 of the seal cover member 170 faces the seal breaking groove 152b formed in the base portion 152 of the main body side sealing portion 150. Since the IC tag seal seal 185 is affixed to the pedestal portion 152 to cover the groove breaking groove 152b, the tip 173a of the breaking projection 173 is connected to the seal breaking groove 152b via the IC tag seal seal 185. Close proximity.

  In the state where the seal cover member 170 is attached as described above, as can be seen from FIG. 17C, the sealing space 110 is only partially blocked by the seal cover member 170, and the rear surface of the seal cover member 170 ( A space is left between the front surface) and the rear wall 161a of the lid-side sealing portion 160. The engagement holding member 175 is inserted into the remaining sealing space 110 as shown by an arrow E in FIG.

  The engagement holding member 175 has a rectangular holding member body 176 that is open at the right end and has a rectangular space (concave portion) inside, and protrudes forward at the left end of the holding member body 176. It is comprised from the plate-shaped stopper part 178. FIG. A pair of upper and lower engaging arms 177 are formed on the plate-like portions forming the front and rear surfaces of the holding member body 176, and are separated by slits 176a and 176a to be cantilevered and extend rightward. Engagement protrusions 177a projecting outward (front side is forward and rear side is rearward) are formed at the distal ends of a total of four upper and lower engagement arms 177, respectively. Each engagement arm 177 is cantilevered by a pair of slits 176a and 176a, and is elastically deformed in the front-rear direction so that the tip portion can swing.

  When the engagement holding member 175 configured as described above is inserted into the sealing space 110 as indicated by an arrow E in FIGS. 19 and 21, the engagement protrusion formed at the front end of the front and rear engagement arms 177. The front-rear dimension of 177a is set to be larger than the front-rear dimension of the sealing space 110, and the engaging protrusion 177a is pushed into the sealing space 110 so that the engaging arm 177 is elastically bent inward. When the engagement holding member 175 is inserted all the way into the sealing space 110, the engagement protrusions 177a are engaged with the engagement recesses 162 of the lid side sealing portion 160 and the seal cover member 170 as shown in FIG. And the elastic deformation of the engagement arm 177 returns to the original state and enters the engagement recesses 162 and 174. As shown in the figure, the engaging protrusion 177a is tapered on the front end side so that it can smoothly enter the sealing space 110, but the rear end side is formed with a step that bends at a right angle. If it enters the engaging recesses 162 and 174, it cannot be pulled out. As a result, the seal cover member 170 and the engagement holding member 175 (that is, the seal breaking member 120) are detachably coupled and held to the lid side sealing portion 160.

  As can be seen from the above description, when the case lid member 60 is closed on the case body member 50 as shown in FIG. 3, the case body member 50 and the case lid member 60 are engaged by the unauthorized opening prevention mechanism 90. In this state, the seal cover member 170 and the engagement holding member 175 are inserted into the seal space 110 opened at the left end of the case seal portion 100 as described above, and the base portion 152 is inserted by the seal cover member 170. In a state where the IC tag seal seal 185 affixed to the cover is covered, it is engaged and held by the engagement holding member 175 and is integrally coupled to the lid side seal portion 160. Here, the IC tag sealing seal 185 has an IC tag 187 and an antenna line 188, and is held inside the main body side sealing part 150 and the lid side sealing part 160 via the antenna line 188. Various information (for example, information about the pachinko machine PD, identification information of the control board 51, etc.) stored in the IC tag 187 by radio can be read without opening the case lid member 60 from the outside.

  Next, the case where the case lid member 60 is released from the state where the case body member 50 and the case lid member 60 are engaged and held in the closed state as described above will be described. To open the case lid member 60, first, the connecting portion 94 that connects the case lid member 60 and the lid side engaging portion 93 in the unauthorized opening prevention mechanism 90 is cut. As a result, the lid-side engagement portion 93 in the unauthorized opening prevention mechanism 90 can be removed and the coupling member 95 disposed therein can also be removed. As a result, the connection between the case main body member 50 and the case lid member 60 is cut off, and the case lid member 60 is slid in the left direction with respect to the case main body member 50 to move the locking projection 62 from the locking groove 54b. The case cover member 60 can be removed from the case body member by moving to a position where it can be removed.

  Thus, when the case lid member 60 is slid in the left direction with respect to the case body member 50, the IC tag sealing seal 185 is configured to be broken by the breaking protrusion 173 of the seal cover member 170. This will be described below. As shown in FIG. 18, when the case body member 50 and the case lid member 60 are engaged and held in the closed state, the tip 173 a of the breaking protrusion 173 of the seal cover member 170 is interposed via the IC tag seal seal 185. When the lid-side sealing portion 160 is slid to the left (in the direction of arrow F) together with the case lid member 60 from this state, it is opposed to the seal breaking groove 152b. Since the seal cover member 170 is held by the sealing portion 160, the seal cover member 170 is also slid to the left as a unit.

  As a result, as shown in FIG. 22, the tip 173a of the breaking protrusion 173 of the seal cover member 170 enters the seal breaking groove 152b while cutting the IC tag seal seal 185. Here, the tip 173a is formed in an acute angle shape, which reliably tears the IC tag seal seal 185, so that the breaking projection 173 enters the seal breaking groove 152b. As described above, when the case lid member 60 is slid leftward with respect to the case main body member 50 to remove the case lid member 60 from the case main body member 50, the IC tag seal seal 185 is reliably broken by the breaking protrusion 173. And prevent its reuse. In particular, if the seal member 186 of the IC tag seal seal 185 is broken, the antenna wire 188 will be broken even if the IC tag 187 itself cannot be broken, so that the IC tag seal seal 185 cannot be reused. it can.

  In addition, although the example using the IC tag seal seal 185 provided with the IC tag 187 and the antenna wire 188 has been described above, a sheet-like seal seal without the IC tag 187 and the antenna wire 188 is used instead. It may be used.

  Further, in the above, an example in which the main board case having a configuration in which the case lid member 60 is slid with respect to the case body member 50 and the case lid member 60 is coupled to the case body member 50 in a closed state has been described. The case sealing portion may be used for a case in which the case lid member is hingedly engaged with the member and is swingably opened and closed. In this case, in the case sealing portion, the case sealing portion is rotated by 90 degrees with respect to the arrangement position in the above-described configuration, and the breaking protrusion is attached to the IC tag sealing seal by the movement in the direction of opening the case lid member. It will be configured to break.

  In the above, the example in which the seal breaking member 120 is constituted by two members, that is, the seal cover member 170 and the engagement holding member 175 has been shown. However, the seal breaking member is not limited to this, and is constituted by one member. May be. In this case, the breaking protrusion is not always configured to project outward from the body, but is configured to be housed inside and configured to be capable of projecting by a link mechanism or the like. Then, when the seal breaking member is inserted into the sealing space, the breaking projection protrudes to the outside by the action of the link mechanism or the like by being brought into contact with the lid-side sealing portion, and the breaking thus protruding The protrusion is used to break the sealing seal when the case lid member is opened.

  Moreover, in the above, an example in which the case sealing structure of the present invention is applied to a control board case of a pachinko machine has been described, but the case sealing structure of the present invention is not limited to this, a gaming machine other than a pachinko machine, For example, the present invention can be applied to a control board case of a slot machine, and can also be applied to various other cases.
