The gap between the pair of cutter member legs 140b is an interval at which the shaft support main body 103b ′ of the seal cover 103 can be fitted within the gap. Has been. Further, the receiving portion 140b ″ is formed such that the bearing portion on the side where the sharp blade 140c is formed is longer than the bearing portion on the other side.
Accordingly, as shown in FIG. 15, in a state where the shaft support portion shaft member 103 b ″ of the seal cover 103 is indented into the seal cover support portions 101 b and 102 b of the upper case 101 and the lower case 102, The tip of the bearing 140b '' is inserted into the gap formed by the seal cover support portions 101b, 102b and the seal cover 103 across the shaft support body 103b ', and then the seal cover 103 is When the seal mounting portions 105 and 106 are rotated from the open state shown in FIG. 15, the bearing portion 140b '' of the cutter member 140 is placed in the gap between the seal cover 103 and the seal cover support portions 101b and 102b. While being sandwiched, the bearing portion 140b ″ is rotated about the rotation axis.

  On the other hand, as shown in FIGS. 16 and 17, the seal cover 103 is provided with an engaging protrusion 103d at the end having the engaging portion 103a, as in the first embodiment. In the second embodiment, the protrusion 103e is provided on the inner side of the seal cover 103 so as to face the engaging protrusion 103d.

Next, a procedure until the main board 115 is housed and sealed in the board case 100 configured as described above will be described with reference to FIGS.
As shown in FIG. 9, each member is attached to the seal mounting portions 105 and 106 in the order of the seal cover 103, then the cutter member 140, and finally the sealing seal.

First, as shown in FIG. 15, with the opening portion of the seal cover 103 facing upward, the shaft support portion shaft member 103b '' of the shaft support portion 103b is fitted into the seal cover support portions 101b and 102b of the upper case 101 and the lower case 102, The seal cover 103 is in a state of being rotatable about the shaft support shaft member 103b ″ as the rotation center. As a result of this operation, a rotation shaft is formed by the shaft support shaft member 103b ″ between the upper case seal cover support portion 101b and the lower case seal cover support portion 102b.
Next, with the cutter member 140 facing the side on which the sharp blade 140c is formed, the rotating shaft (that is, the shaft support portion shaft member 103b ″ of the seal cover 103) formed in the above operation is supported by the bearing portion 140b. ”Is inserted into the cutter member gap P of both the seal mounting portions 105 and 106 while contacting.

Next, the seal sticker 108 is affixed to both the seal attachment parts 105 and 106 (FIG. 10).
Next, the seal cover 103 is rotated so as to cover both the seal mounting portions with the shaft support shaft member 103b ″ as the rotation center.
When the seal cover 103 covers both the seal mounting portions 105 and 106, as shown in FIG. 16, the engagement protrusion 103d provided on the outer side of the seal cover 103 gets over the engagement protrusion 120d of the caulking fixing means 120. At the same time, the raising protrusion 103e provided on the inner side of the seal cover gets over the raising portion 140a of the cutter member 140, and the seal cover 103 completely covers both the seal mounting portions 105 and 106 (FIGS. 11 and 12).
In this state, the one-way screw in the first caulking screw storage portion 121a is in a position where it can be inserted into the engagement hole 103a ′ of the seal cover 103, and the seal cover 103 is temporarily fixed to the upper case 101 and the lower case 102. In addition, the raising portion 140a of the cutter member 140 is in a state of being caught by the raising projection 103e of the seal cover 103.

Next, when the one-way screw housed in the first caulking screw housing part 121a is screwed in with an appropriate jig, the screw tip passes through the engagement hole 103a ′ of the seal cover 103 and the caulking screw is fixed. The upper case 101 and the lower case 102 are caulked and fixed, and the seal cover 103 is engaged (caulking and fixed).
Thereby, the sealing of the substrate case 100 is completed.

In order to take out the main board 115, it is necessary to remove the seal cover 103 and release the caulking and fixing between the upper case 101 and the lower case 102.
To remove the seal cover 103, it is necessary to remove the caulking screw housed in the first caulking screw housing part 121a. However, since this screw is a one-way screw, it is simply turned in the direction opposite to the caulking direction (screwing direction). However, the screw cannot be removed.
Therefore, in order to remove the seal cover 103, first, the engagement portion neck portion 103c connecting the engagement portion 103a of the seal cover 103 and the seal cover 103 is cut using a jig such as a nipper.
Next, when the pivot support shaft member 103b ″ is pivoted to remove the seal cover 103, as shown in FIGS. 13 and 14, the raising portion 140a of the cutter member 140 is moved along with the pivoting operation. The cutter member 140 is rotated along with the seal cover 103, and is stuck across the first seal mounting portion 105 and the second seal mounting portion 106. The sealed seal 108 is broken by the sharp portion 140 c of the cutter member 140.

Next, the first caulking screw storage part 121a is separated using a jig such as a nipper.
As a result of the operations up to this point, all of the upper case 101 and the lower case 102 that have been joined have been removed, and thereafter the substrate case 100 is opened by sliding the upper case 101 and the lower case 102. be able to.

  As described above, in order to release the seal of the substrate case 100, the first caulking screw storage portion 121a must be separated. Therefore, if the trace is observed, it is surely found that the seal of the substrate case 100 is released. be able to. Further, in order to release the sealing of the substrate case 100, it is necessary to remove the seal cover 103, but the IC tag 108a is destroyed in the process of removing the seal cover 103. Therefore, even if the reader device is brought closer, it becomes impossible to read the identification information stored in the IC tag 108a, thereby reliably detecting that an illegal act has been performed.

That is, when the substrate case 100 is illegally opened and the ROM or the like of the main substrate 115 is replaced, a cut trace always remains, and the seal seal 108 is broken to destroy the IC tag 108a. Therefore, according to the second embodiment, it is possible to discover that the sealing of the substrate case 100 has been reliably released by both visual observation and a reader machine.
Further, the cutter member 140 can be set by a simple operation of inserting the cutter member 140, covering the seal cover 103, and screwing the one-way screw, and fixing the seal cover 103 and fixing the caulking at the same time. The work load can be reduced, and the structure itself can be simplified compared to the conventional example.
Further, the cutter member 140 is installed in the cutter member gap P by using the rotary shaft formed by the indentation of the shaft support portion shaft member 103b ″ of the seal cover 103 into the case seal cover support portions 101b and 102b. This can be done very easily by sharing the rotation shaft 140.

  In the above embodiment, the upper case 101 and the lower case 102 are configured to overlap with each other by sliding fitting. Instead of this configuration, the upper case 101 and the lower case 102 can be opened and closed via a hinge. It can also be configured.

In the above embodiment, the substrate case 100 that houses the main substrate 104 has been described. In addition to the above, the above-described effect control processing unit 12a, special symbol display control unit 12b, lamp control processing unit 12c, payout It can also be used as a case for storing the control processing unit 12e and the control board of the firing control processing unit 13.
Of course, it can also be used for a pachislot machine.
