Description

  The present invention relates to an opening number limiting sealing device used for sealing a board case of a gaming machine.

  A gaming machine such as a pachinko gaming machine or a slot machine is usually equipped with a microcomputer, and a game progresses based on data stored in a ROM of the microcomputer, and a jackpot probability is determined. For this reason, when illegally remodeling a gaming machine and trying to acquire many prize balls illegally, the ROM of this microcomputer is replaced with a ROM storing an illegal jackpot probability and the like to increase the jackpot probability. In some cases, an illegal act of illegally obtaining a large number of prize balls may be performed.

  For this reason, the control board on which the microcomputer including the ROM is mounted is usually housed in the board case, and the board case lid is closed and sealed with sealing paper or the like.

  However, the control board housed in the board case of the gaming machine is manufactured and shipped to each hole, and then, during adjustment, repair, inspection, etc., or when the inspection agency enters the hall, etc. The circuit board on the control board may be inspected by opening the board case. For this reason, it is necessary to peel off the sealing paper at the time of inspection or inspection to open the substrate case, and there has been a demand for a sealing device in which such opening is performed only a limited number of times.

Therefore, conventionally, in the following Patent Document 1 or the like, as a substrate case locking device, a locking mechanism using a cylinder lock is attached to a cover part or lid of the substrate case, and between the key guard cover member and the case body covering the cylinder lock, In addition, a sealing-type locking device has been proposed in which a plurality of sealing portions are provided between the lid and the case body so as to be openable.
JP 2006-102551 A

  In this type of conventional sealing device, a plurality of sealing parts are formed on a part of the case body by a synthetic resin or the like so as to be able to be shredded. When the substrate case is opened, the sealing part being sealed is shredded. In this state, the upper lid of the substrate case is opened to perform adjustment work and inspection work. And after the work is finished, seal the substrate case again using a new sealing part, and if it becomes necessary to open the substrate case again, the sealing part that has been sealed again is torn off and opened, The lid of the substrate case is opened to perform adjustment work and inspection work.

  For this reason, it may be difficult to perform the shredding operation when tearing the opened sealed part, and it is easy to throw away the sealed part around the gaming machine, and the sealed part becomes dust. There was a problem that dust was easily generated. Furthermore, since the sealing part of this type of sealing device is usually manufactured by being integrally molded with a part of the case body or lid of the substrate case using a synthetic resin, the substrate after the sealing part has been shredded. There has been a problem that the case becomes damaged and can no longer be reused, and the substrate case cannot be reused and the recyclability is deteriorated.

  The present invention solves the above-mentioned problems, can reliably perform a predetermined number of seals, eliminates the generation of dust due to tearing off the seals and the like, and enables reuse of parts. An object of the present invention is to provide a sealing device for limiting the number of opening.

  The sealing device for limiting the number of opening according to the present invention is a sealing device for limiting the number of opening, which seals the lid of the case within a predetermined number of opening, the case or a part of the lid, A locking dial having a ratchet mechanism and pivotable in only one direction is pivotally mounted, and the locking dial has a number of locking claws protruding from the outer periphery of the locking dial. The locking claw can be pushed inside the locking dial and cannot be re-projected, and protrudes from the locking dial to a part of the lid or the case opposite to the locking dial. A locking portion for locking the locking claw is provided. In addition, the said cover body is the concept containing opening-and-closing bodies, such as a door which can be opened and closed.

  Here, the locking claw is provided on the outer periphery of the locking dial so as to be able to protrude, forms a space on the inner side, and has a check piece on the outer side, and an inner side of the locking claw member And a claw support member inserted so as to be able to advance and retreat. When the locking claw member is pushed into the locking dial, a locking portion to which the check piece is locked is inserted into the locking dial. Can be provided.

  A locking portion provided on a part of the lid or case and to which the locking claw is locked has a locking recess into which the locking claw enters and a locking surface on which the locking claw comes into contact. Can be provided.

  The sealing device for limiting the number of openings having the above-described configuration rotates a locking dial provided with a ratchet mechanism in one direction so as to be able to rotate, and locks the locking claw with a locking portion on the opposite lid or case side. . As a result, the case is sealed. When opening, the locking claw is pushed into the locking dial, the locking is released and the opening is opened. When the unlocked claw is pushed into the locking dial and cannot be re-projected, when the opened case is sealed again, the locking dial is turned and the new locking claw is opposed. Lock it on the body or case side and seal it.

  In this way, since the latching claws once sealed and opened cannot be used again, they can be previously attached to the latch dial and sealed as many as the number of latching claws. In addition, since the locking claw is pushed into the locking dial and opened, dust is not generated by tearing off the sealing part, etc. as in the past, and if the locking dial is replaced, the case and A lid etc. can be reused and the recyclability of parts can be improved.

As shown in FIG. 3, the abutment dial 10 including the engagement claw member 20 is securely engaged with the engagement portion 3 so as to contact the inner surface of the engagement portion 3, and the lid on which the engagement dial 10 is attached. The body 2 is also configured to be locked in the closed state with respect to the case body 1a.

  The first locking claw T1 to the fourth locking claw T4 attached to the locking dial 10 are colored in different colors or numbered for identification so that the number of times of opening can be easily recognized. Has been.

  Next, the operation of the sealing device for limiting the number of openings having the above-described configuration will be described mainly with reference to FIGS. First, the locking dial 10 of the sealing device is attached in the state shown in FIG. 9 on the front end of the lid 2 in the board case 1 of the gaming machine. That is, the locking dial 10 is mounted in a state where the portion without the locking claw is opposed to the locking portion 3 on the case body 1a side.

  At this time, as shown in FIG. 3, the locking dial 10 has its shaft portion 10 a inserted into a mounting hole drilled at the mounting position of the lid 2, and the inside of the support cylindrical portion 15 inside the lid 2. In addition, the rotating portion 16 is inserted from below, and the shaft portion 10a of the locking dial 10 is inserted into the shaft hole of the rotating portion 16, and the fixing pin 18 is formed in the rotating portion 16 and the shaft portion 10a. The rotating portion 16 is fixed to the tip of the shaft portion 10a, and the locking dial 10 is rotatably mounted.

  At this time, the ratchet pawl 17a of the ratchet mechanism 17 located on the upper portion of the rotating portion 16 is engaged with the ratchet locking portion 17b on the support cylindrical portion 15 side, and the locking dial 10 is unidirectional (clockwise in FIG. 4). It is mounted so as to be rotatable only in the direction).

  In the state where the locking dial 10 is shown in FIG. 9, the lid 2 is closed with respect to the case body 1a, and the annular fitting portion 4 of the lid 2 is upward from the case body 1a side as shown in FIGS. It is fitted on the outer periphery of the protruding locking part 3. Thus, the lid 2 of the substrate case 1 is firmly held in the closed state, and the circuit board 9 is accommodated therein.

  In this state, as shown in the upper diagram of FIG. 10, the locking dial 10 is turned clockwise, and the first locking claw T <b> 1 protruding to the outer periphery is caused to enter the locking recess 3 a of the locking portion 3. The dial is rotated until the first locking claw T1 comes into contact with the stop surface 3b. Since the ratchet mechanism 17 is mounted on the shaft portion 10a of the locking dial 10, the locking dial 10 is in a state in which the first locking claw T1 enters the locking recess 3a and contacts the locking surface 3b. The lid 2 of the substrate case 1 is kept closed, and the first sealing is performed.

  When opening the first seal, the first locking claw T1 is pushed into the locking dial 10 as shown in the lower diagram of FIG. At this time, the locking claw member 20 enters the locking dial 10, and at this time, the check piece 20a of the locking claw member 20 is detached from the locking wall 10b and is disengaged to the inside (the shaft portion 10a side). . At this time, since the check piece 20a is expanded, the check piece 20a cannot be returned into the locking wall 10b, and the pushing state of the first locking claw T1 into the dial is maintained as shown in the lower diagram of FIG. The Therefore, as shown in the figure, the lock by the lock dial 10 is released and the bag is opened, and the lid 2 of the substrate case 1 can be opened.

  Thereafter, after the lid 2 is opened and the internal circuit board 9 is inspected and adjusted, and then the lid 2 is closed again and the substrate case 1 is sealed, the locking dial 10 is turned clockwise to The second locking claw T2 projecting into the locking portion 3 enters the locking recess 3a of the locking portion 3, and the dial is rotated until the second locking claw T2 comes into contact with the locking surface 3b. As described above, since the ratchet mechanism 17 is attached to the shaft portion 10a of the locking dial 10, the second locking claw T2 enters the locking recess 3a and engages with the locking surface 3b. The stop dial 10 is locked, the lid 2 of the substrate case 1 is kept closed, and the second sealing is performed.

  When opening the second seal, the second locking claw T2 is pushed into the locking dial 10 in the same manner as described above. At this time, the locking claw member 20 enters the locking dial 10, and at this time, the check piece 20a of the locking claw member 20 is detached from the locking wall 10b and is disengaged to the inside (the shaft portion 10a side). . At this time, since the check piece 20a is expanded, it cannot return to the locking wall 10b, the pushing state of the second locking claw T2 into the dial is maintained, and locking by the locking dial 10 is not performed. The lid body 2 of the substrate case 1 can be opened by being released.

  Thereafter, in the same manner as described above, when the lid 2 is opened and the internal circuit board 9 is inspected and adjusted, and then the lid 2 is closed again and the substrate case 1 is sealed, as shown in FIG. Then, the locking dial 10 is turned clockwise, the third locking claw T3 protruding to the outer periphery is caused to enter the locking recess 3a of the locking portion 3, and the second locking claw T2 comes into contact with the locking surface 3b. Rotate the dial until As described above, since the ratchet mechanism 17 is attached to the shaft portion 10a of the locking dial 10, the third locking claw T3 enters the locking recess 3a and engages with the locking surface 3b. The stop dial 10 is locked, the lid 2 of the substrate case 1 is kept closed, and the third sealing is performed.

  When opening the third seal, the third locking claw T3 is pushed into the locking dial 10 as shown in the lower diagram of FIG. At this time, the locking claw member 20 enters the locking dial 10, and at this time, the check piece 20a of the locking claw member 20 is detached from the locking wall 10b and is disengaged to the inside (the shaft portion 10a side). . At this time, since the check piece 20a is expanded, the check piece 20a cannot be returned into the locking wall 10b, and the third locking claw T3 is pushed into the dial as shown in the lower diagram of FIG. The Therefore, as shown in the figure, the lock by the lock dial 10 is released and the bag is opened, and the lid 2 of the substrate case 1 can be opened.

  Thereafter, in the same manner as described above, when the lid body 2 is opened and the internal circuit board 9 is inspected and adjusted, and then the lid body 2 is closed again and the substrate case 1 is sealed, as shown in FIG. Then, the locking dial 10 is turned clockwise, the fourth locking claw T4 protruding to the outer periphery is caused to enter the locking recess 3a of the locking portion 3, and the second locking claw T2 comes into contact with the locking surface 3b. Rotate the dial until As described above, since the ratchet mechanism 17 is attached to the shaft portion 10a of the locking dial 10, the third locking claw T3 enters the locking recess 3a and engages with the locking surface 3b. The stop dial 10 is locked, the lid 2 of the substrate case 1 is kept closed, and the fourth sealing is performed.

  Thus, since the locking claws once sealed and opened cannot be used again, the number of the locking claws previously attached to the locking dial 10 (in this example, 4 of the first locking claw T1 to the fourth locking claw T4). Can only be sealed. Further, since the locking claw is pushed into the locking dial 10 and opened, dust is not generated by tearing off the sealing portion or the like as in the prior art. Further, if the locking dial 10 is replaced, the substrate case 1 and the lid 2 can be reused, and the recyclability of the parts can be improved.

  In addition, although the example applied to the substrate case of the gaming machine has been described in the above embodiment, the present invention can also be applied to a sealing device that is a case other than the substrate case and has an opening restriction on the lid. It is. In the above description, the locking dial 10 is attached to a part of the lid 2 and the locking part 3 is provided on the case body 1a.
