Thereby, the annular projection 123a of the support shaft portion 123 is rotatably arranged within the groove 503b formed in the bearing forming portion 503a of the hinge sealing cover 44. Finally, as described using FIG. 19C, the main engagement claw 411d of the first engagement member 411 for B caulking is engaged with the second notch 501c of the hinge sealing cover 44. Thereby, the main control board unit 16 is held at the fixed position shown in FIG. 20.

In this embodiment, by rotating the main control board unit 16, it can be held at the inspection position shown in FIG. 21. Specifically, while the main control board unit 16 is held in the fixed position shown in FIG. 20, first, the first case fixture 161 and the second case fixture 162 are rotated and held in the case release position. . Then, by rotating the main control board unit 16 downward, the main control board unit 16 can be held at the inspection position. Thereby, the back surface of the main control board 20 can be easily inspected. Therefore, if traces of fraudulent activity appear on the back side of the main control board 20, the traces can be easily recognized visually. This makes it easier to discover fraudulent acts on the main control board.

Furthermore, in this embodiment, the bearing forming part 331 formed on the board case 41 (front case 300) and the bearing forming part 503a formed on the hinge sealing cover 44 attached to the board case 41 (front case 300) , a bearing portion that rotatably supports the support shaft portion 123 of the case holder 100 is formed. The hinge sealing cover 44 and the board case 41 are engaged with each other by a first engaging member 411 for B caulking or a second engaging member 412 for C caulking. Therefore, when B caulking (main body caulking) or C caulking (main body recaulking) is released, traces remain on the hinge seal cover 44, the board case 41, and the first engaging member 411 (or the second engaging member 412). It becomes like this. Thereby, security can be improved.

Furthermore, in this embodiment, the front wall of the third engaged portion forming body 341 of the front case 300 is present on the front side of the third engaging member 421 for A caulking (FIGS. 10A and 11A). , see FIG. 12A). On the other hand, the front wall of the fourth engaging member holding portion 212 of the rear case 200 exists on the front side of the fourth engaging member 422 for A caulking (see FIGS. 10A, 11A, and 14A).

When releasing the engagement by the third engaging member 421, after cutting off the thin wall portion 341d of the front wall of the third engaged portion forming body 341 of the front case 300, The portion 421c is cut with a tool.

Therefore, in order to destroy the third engaging member 421, it is necessary to destroy the front wall of the third engaged part forming body 341 of the front case 300, and in order to destroy the fourth engaging member 422, it is necessary to destroy the front wall of the third engaged part forming body 341 of the front case 300. , it is necessary to destroy the front wall of the fourth engaging member holding portion 212 of the rear case 200.

Therefore, it is difficult to destroy the third engagement member 421 and the fourth engagement member 422 by destroying only one of the front case 300 and the rear case 200. This can prevent the front case 300 or the rear case 200 from being misused after the third engagement member 421 and the fourth engagement member 422 are destroyed.

Further, in this embodiment, the first engagement member 411 for B caulking and the second engagement member 412 for C caulking are integrally connected by a connecting member 413. In other words, the first engaging member 411, the second engaging member 412, and the connecting member 413 constitute the engaging member composite body 410. Then, in a state where the hinge seal cover 44 and the board case 41 are engaged with each other by the first engaging member 411, the hinge seal cover 44 and the board case 41 cannot be engaged with each other by the second engaging member 412. Become. On the other hand, after the first engagement member 411 is cut, the hinge seal cover 44 and the board case 41 can be engaged with each other by the second engagement member 412.

As a result, C-caulking is performed using the engagement member composite body 410 after the first engagement member 411 has been cut. This makes it easier to determine whether or not the main body has been re-swaged without any fraud.

Further, when the engagement between the hinge seal cover 44 and the board case 41 by the first engagement member 411 is released, the main engagement of the first engagement member 411 for B caulking in the engagement member composite 410 is canceled. The matching claw 411d is missing. Therefore, it is difficult to illegally reuse the engagement member composite body 410 after the engagement is released.

Furthermore, even if the engaging member composite 410 from which the main engaging claw 411d has been removed is reversed in the vertical direction and the second engaging member 412 is inserted into the first opening 305b of the composite body holding portion 305, the Since the rear part of the connecting member 413 interferes with the front protruding wall 303a of the front case, the second engaging member 412 cannot be inserted into the first opening 305b. In other words, the second engagement member 412 for C caulking in the engagement member composite 410 from which the main engagement claw 411d has been removed cannot be used as the first engagement member 411 for B caulking. This makes it difficult to illegally reuse the engagement member composite 410 after the first engagement member 411 is disengaged.
