At this time, thereafter, the substrate accommodation unit A is fixed to the fixed position in a non-rotatable manner by the sealing pin P2. At that time, the engagement portion 4d of the mounting portion B is engaged with the substrate housing case 1, so that the sealing pin P2 can be inserted in a state where the substrate housing case 1 is temporarily fixed at a fixed position, thereby improving workability. To do. Thereby, the sealing with respect to the attachment part B of the board | substrate accommodation unit A is completed.

  In the state where the substrate housing case 1 is located at the fixed position, the removal of the detachable member 34 is restricted. That is, as shown in FIG. 11A, in order to remove the detachable member 34 with the substrate housing case 1 positioned at the fixed position, the detachable member 34 needs to be extracted in the direction of the arrow d3. Since the attachment part B and the back plate 242 exist in the extraction direction, it is difficult to extract the detachable member 34. Further, the operation part 34h is stored in the attachment part B, and it is difficult to operate the operation part 34h from the outside. For this reason, it is difficult to release the engagement between the engaging portion 34f and the engaging portion 33d, and it is difficult to remove the detachable member 34 from this point. Therefore, it is possible to increase the difficulty of fraud by removing the detachable member 34 during the sealing of the substrate housing unit A.

  Next, the operation at the time of inspection of the main control board 2 will be described. The front side of the main control board 2 is visible from the outside of the board housing case 1, but the back side is difficult due to the presence of the back plate 242 and the like. In order to inspect the back surface of the main control board 2, first, the sealing pin P2 is removed, and the sealing of the board housing unit A with respect to the mounting portion B is released. As a result, the substrate housing case 1 is rotatable around the hinge shaft 31. As shown in FIGS. 11B and 12, the substrate housing case 1 is rotated to the front side. As a result, the back surface 21 of the substrate housing case 1 is exposed, and the back surface of the main control board 2 can be inspected through the back surface 21. In this embodiment, since the board | substrate accommodation case 1 is the structure rotated, space saving can be achieved compared with the structure to slide. Further, when the substrate housing case 1 reaches a position rotated by a certain amount from the fixed position, the detachable member 34 can be removed. When the detachable member 34 is removed, the hinge shaft 31 and the shaft hole 32a can be separated, and the substrate housing case 1 can be detached from the attachment portion B.

  In the case of the present embodiment, the substrate housing case 1 can be turned to the front side by 90 degrees or more from the fixed position. The confirmation of the back surface of the main control board 2 can be easily performed, for example, when the rotation angle θ (FIG. 12) reaches an angle exceeding 90 degrees. The example of FIG. 12 is 120 degrees. When the rotation angle θ exceeds 90 degrees, the attachment / detachment of the attachment / detachment member 34 becomes easy. Therefore, when detailed inspection is required as a result of confirmation of the back surface of the main control board 2 through the board housing case 1, the detachable member 34 can be removed to separate the board housing case 1 from the mounting portion B. . Since visual inspection and removal of the substrate housing case 1 can be performed continuously, the number of work steps can be reduced. Even when the substrate storage case 1 is discarded, the detachable member 34 can be reused.

<Fixed part>
The configuration of the fixing portion 40 will be described. The fixing part 40 is a part for fixing the case member 20 which is the upper case member 10 with a curable resin. The curable resin may be anything as long as it is curable from a liquid state. For example, it may be an ultraviolet curable resin that is cured by irradiation with ultraviolet rays.

  Referring to FIGS. 5 and 6, fixing portion 40 includes case portion 41 formed integrally with upper case member 10, case portion 42 formed integrally with lower case member 20, and case portion 41. And a support member 43 which is a separate member, and a sealing member 44 supported by the support member 43.

  The case portions 41 and 42 are portions constituting a wall portion that defines a filling space for the curable resin (filling space S in FIG. 13 and the like). In the case of the present embodiment, the filling space S is a rectangular parallelepiped space as a whole, the case portion 41 constitutes its side wall portion (upper and lower left and right side wall portions), and the case portion 42 has its bottom wall (back side wall). Part). In the case part 41, a beam-like fixed part 41a extending in the left-right direction is integrally formed. The case portion 42 is formed with a pair of wedge-shaped fixed portions 42a extending in the depth direction. The to-be-adhered portions 41a and 42a are not necessarily provided, but by providing these, the adhering force with the case member 20 which is the upper case member 10 made of a curable resin can be increased.

  The support member 43 is a U-shaped or gate-shaped member having a pair of leg portions 43A and a top portion 43B connecting the ends of the pair of leg portions 43A. The leg portion 43A is formed with an engaging portion 43a that engages with the fixed portion 42a. In the present embodiment, the leg portion 43A is an engaging hole. In the present embodiment, the support member 43 is a metal member, but may be a resin member.

  In the case of this embodiment, the sealing member 44 is affixed and supported by the top part 43B. The sealing member 44 is a member that is embedded in the curable resin filled in the filling space S and leaves a trace of removing the curable resin. FIG. 17A is an exploded view showing a configuration example of the sealing member 44. In the example of the figure, the sealing member 44 is configured by a laminated sheet member composed of a plurality of layers (four layers). Specifically, the sealing member 44 is configured by laminating an outermost hologram foil 44a, an adhesive material 44b, a base material 44c, and an adhesive 44d.

  The hologram foil 44a is a metal foil on which a hologram is displayed, for example, an aluminum foil having a thickness of 0.05 μm. The adhesive material 44b is a member that bonds the base material 44c and the hologram foil 44a. The base material 44c is a member for ensuring the strength of the sealing member 44 in order to facilitate handling, and is, for example, a PET sheet having a thickness of 120 μm. The adhesive material 44d is a member that bonds the top portion 43B and the sealing member 44 together. By using the sealing member 44 as a sheet member that is affixed to the support member 43, its installation and replacement after finding an illegal act are easy, and workability is improved.

  Next, the assembly procedure of the fixing part 40 and the structure after the assembly will be described with reference to FIGS. FIG. 13A shows a state in which the upper case member 10 and the lower case member 20 are combined, and the case portion 41 is overlaid on the case portion 42, and only the front side (upper side in the figure). The filling space S is opened. An open end of the filling space S is defined by an edge 41b of the case portion 41, which serves as an insertion port for the support member 43 and an injection port for a curable resin. The edge 41b may be referred to as an inlet 41b.

  Next, the support member 43 to which the sealing member 44 is previously attached is inserted into the filling space S. FIG. 13B and FIG. 14A show an embodiment after the support member 43 is inserted, and FIG. 15A is a cross-sectional view taken along the line II-II in FIG. Each engagement portion 43a of the support member 43 is engaged with the fixed portion 42a of the case portion 42, and it is difficult to remove the support member 43 without releasing the engagement. The to-be-adhered part 41a is interposed between the top part 43B of the support member 43 and the bottom wall part of the filling space S (a part of the case part 42). For this reason, even if it is going to separate the to-be-adhered part 41a and the to-be-adhered part 42a in the front-back direction (up-down direction in the same figure), it will be restrained by the support member 43 and will become difficult to separate. In other words, it is difficult to separate the upper case member 10 and the lower case member 20 by the support member 43.

  FIG. 14B shows a state in which the curable resin 45 is filled into the filling space S from the inlet 41b, and FIG. 15B is a cross-sectional view taken along the line III-III in FIG. 14B. The sealing member 44, the support member 43, and the fixed portions 41 a and 42 a in the filling space S are embedded in the curable resin 45, and the fixing portion 40 is completed by the curing of the curable resin 45, and the substrate housing case 1. Is sealed. The sealing member 44 is located at a position facing the opening 41b. Since the curable resin 45 is a permeable resin, the sealing member 44 can be visually confirmed from the outside.

  FIG. 16 shows an example of an illegal act against the fixing portion 40. After the curable resin 45 is heated and softened, the curable resin 45 is dug and removed illegally by a tool T such as a driver. Since such traces remain on the sealing member 44, the cheating can be found. FIGS. 17B and 17C are explanatory diagrams thereof.

  FIG. 17B shows a state in which the sealing member 44 is embedded in the curable resin 45 in the filling space S. FIG. 17C shows a state in which the curable resin 45 is removed by the method illustrated in FIG. When the curable resin 45 is removed, at least a part of the sealing member 44 fixed to the curable resin 45 (a part of the hologram foil 44a in the figure) is removed together with the curable resin 45, and the trace remains. It will be.

  In the case of the present embodiment, particularly between the fixed portions 41a and 42a is fixed by the curable resin 45, and when the substrate housing case 1 is opened by an illegal act, it is essential to separate the fixed portions 41a and 42a. Therefore, it is essential to remove the surrounding curable resin 45. Since the sealing member 44 is located between the injection port 41b and the fixed portions 41a and 42a, the tool T is inserted from the injection hole 41b to remove the curable resin 45 around the fixed portions 41a and 42a. Then, the sealing member 44 must be damaged, and a trace of fraudulent activity remains with a high probability. Further, since the sealing member 44 is supported by the top portion 43B of the support member 43, the position of the sealing member 44 in the filling space S is a fixed position. Therefore, even if no visible trace remains on the sealing member 44 itself, there is a possibility that a trace such as the position of the sealing member 44 may be left behind, and a trace of fraudulent activity will remain with a high probability. When placing the sealing member 44 in a fixed position, the support member 43 is not indispensable, but it is easier to place the support member 43 in a fixed position by supporting it with the support member 43. Further, since the support member 43 is a metal member, it is stronger. It is possible to arrange in a fixed position.
