Two numbered assembly marks 39 are formed. The assembly mark 39 is formed on the back side portion of the lid side engaging portion 60 to which the identification mark 38a of “Circle 1” is numbered on the front surface of the case lid member 30, and includes eight sets of body side engaging portions. 50 and the lid-side engaging portion 60, the lid-side engaging portion 60 of the first group to be engaged (that is, the identification mark 38a of “Round 1” is assigned on the front surface of the case lid member 30) is indicated. It will be. Further, since the assembly mark 39 is formed on the rear surface (edge) of the storage frame portion 37, the main control board 16 is attached to the inside of the case lid member 60 as shown by a two-dot chain line in FIG. Even in the state, it is visible from the inside of the case lid member 60.

  Thus, in the production process of the main board assembly MBA, the lid side engaging part 60 (and the main body side engaging part 50) to be engaged first with the main control board 16 attached to the inside of the case lid member 30. ) Can be immediately determined and the connection member 70 can be engaged without making a mistake, and the assembly time of the substrate case 15 (main substrate assembly MBA) in the production process can be shortened.

  As shown in FIG. 13, the connection member 70 includes a resin connection main body portion 71 having a shape in which a partition wall is provided at the center of a hollow cylinder penetrating in the axial direction. Are formed 180 degrees apart in the circumferential direction, and a pair of rotation regulating recesses 73 are formed 180 degrees apart in the circumferential direction on the other axial end side. The connection main body 71 further has a pair of engaging projections 74 formed in a positional relationship 90 degrees away from the rotation restricting recess 72 in the circumferential direction in the vicinity of one end side, and 90 in the circumferential direction from the rotation restricting recess 73 in the vicinity of the other end side. A pair of engaging protrusions 76 are formed in a positional relationship that is separated by a distance.

  The engagement protrusions 74 and 76 are surrounded by U-shaped cutouts 75a and 77a, are separated from the connection main body 71, are connected to the connection main body 71 at the base portions 75b and 77b, and are elastic around the base portions 75b and 77b. It can swing in the radial direction by deformation. Both the engaging protrusions 74 and 76 protrude outward from the outer peripheral surface of the connection main body 71 in a free state. However, when pressed inward in the radial direction, the engaging protrusions 74 and 76 swing inward in the radial direction around the base portions 75b and 77b. Move.

  In the main board assembly MBA configured as described above, in order to close and hold the case lid member 30 with respect to the case main body member 20 by the unauthorized opening prevention mechanism DPM1, first, for example, the assembly mark 39 of the case lid member 30 indicates. One end side of each connection member 70 is inserted into the lid side engaging space 65 of the (two) lid side engaging portions 60.

  At this time, the connection member 70 is inserted into the lid-side engagement space 65 by aligning the engagement protrusion 74 on one end side with the lid-side engagement recess 64 in the circumferential direction. In addition, the lid side rotation restricting protrusion 63 enters the rotation restricting recess 72 by positioning so that the engaging protrusion 74 enters the cover side engaging recess 64 in this way. In other words, the lid side rotation restricting projection 63 interferes with the insertion of the connection member 70 at a rotational direction position different from the alignment direction, and the insertion cannot be performed. As a result, the engaging protrusion 74 that is in contact with the side wall portion of the lid-side cylindrical portion 61 is pushed inward and elastically deformed, and then enters the lid-side engaging recess 64 to engage with the original shape. The connection member 70 is engaged and held by the lid side engaging portion 60 in a state where the one end side is inserted. Note that this operation only requires a pressing force to elastically deform the engagement protrusion 74 inward, and can be easily performed manually without using a tool.

  Next, the case lid member 30 is rocked and attached to the case body member 20 in a closed manner. At this time, as shown in FIG. 5, the edge of the engagement base portion 26 in the case main body member 20 is smoothly guided to the inside of the edge portion of the housing frame portion 37 in the case lid member 30 by the guide rib 27. Further, at this time, the left and right and lower edges (side walls) of the main body side case casing 21 of the case main body member 20 are also the left and right and lower edges (side walls) of the lid side case casing 31 of the case lid member 30. Part).

  Further, when the case lid member 30 is attached to the case body member 20 in a closed manner, as shown in FIG. 4, the lid side engaging portion 60 overlaps the main body side engaging portion 50 and the lid side engaging portion 60 The other end side of the connecting member 70 that is engaged and held and protrudes is inserted into the main body side engaging space 55 of the main body side engaging portion 50. As a result, the engaging protrusion 76 that contacts the side wall portion of the main body side cylindrical portion 51 is pushed inward and elastically deformed, and then enters the main body side engaging recess 54 to be engaged in the original shape. The connecting member 70 is also engaged and held with the main body side engaging portion 50 in a state where the other end side is inserted. At this time, the connection member 70 is positioned with respect to the lid-side engagement portion 60 so that the engagement protrusion 74 enters the lid-side engagement recess 64 and the lid-side rotation restriction projection 63 enters the rotation restriction recess 72. When the case lid member 30 is closed in this state, the main body side rotation restricting protrusion 53 enters the rotation restricting recess 73. In addition, this operation | work only needs to push the case cover member 30 by hand and it closes on the case main body member 20, and can be easily performed manually.

  As a result, the engagement protrusion 74 of the connection member 70 protrudes into the lid-side engagement recess 64, one end side of the connection member 70 engages with the lid-side engagement portion 60, and the engagement protrusion 76 becomes the main body-side engagement recess 54. The other end side of the connecting member 70 is engaged with the main body side engaging portion 50, and the case lid member 30 is held in the closed state by the case main body member 20 and cannot be removed from the outside. For this reason, it is possible to reliably prevent unauthorized access to the main control board 16 disposed in the case with the case lid member 30 opened, for example, unauthorized access to a ROM (not shown) attached to the main control board 16. .

  Note that the insertion of the connecting member 70 may be reversed. That is, the other end side of the connecting member 70 is inserted into the mounting side engaging space 65 to engage the engaging protrusion 76 with the lid side engaging recess 64, and the lid side engaging portion 60 is connected to the main body side engaging portion 50. One end side of the connection member 70 may be inserted into the main body side engaging space 55 and the engaging protrusion 74 may be engaged with the main body side engaging concave portion 54 when overlapping. For this reason, the connection member 70 is made symmetrical in the axial direction. Further, the insertion order of the connection member 70 may be reversed. That is, after one end side (or the other end side) of the connection member 70 is engaged with the main body side engaging portion 50, the case lid member 30 is closed and the other end side (or one end side) of the connection member 70 is closed. You may make it engage with the side engaging part 60. FIG.

  As described above, the main board assembly MBA, which is closed by the case lid member 30 with respect to the case body member 20 and held by the unauthorized opening prevention mechanism DPM1, is attached to the bracket BR as described above. Although engaged and held by the detachment prevention mechanism DPM2, this operation is performed in the same manner as the unauthorized opening prevention mechanism DPM1 described above.
