The plates 47a and 47b constituting the stopper 47 are provided upright on the right wall 37d and the left wall 37c (the plates 47a and 47b of the left wall 37c are not shown) while extending in the left-right direction and the front-rear direction. ing. Further, these plates 47a and 47b are provided on the rear side of the locking claw 46 so as to sandwich the locking claw 46 in the vertical direction.

  As shown in FIG. 4, a protrusion 51 protruding forward is provided at the front end of each of the plates 47a and 47b. The protrusions 51 provided on the plates 47a and 47b of the right wall 37d are arranged at the front end portion of the plates 47a and 47b and the left end portion. The protrusion provided on the plate of the stopper (not shown) of the left wall 37c is positioned at the right end of the front end of this plate. These protrusions 51 are provided at positions spaced from the right wall 37d or the left wall 37c by a distance D (see FIG. 4) toward the center of the casing 24 in the left-right direction.

  As shown in FIG. 2, the bottom wall 38 of the housing 24 is formed in a flat plate shape having through holes 52 at four corners. The through hole 52 is a hole constituting a part of the mounting structure 36 described later. The through holes 52 are provided at two locations, the upper and lower portions of the left end portion of the bottom wall 38 and the two upper and lower portions of the right end portion. More specifically, these through holes 52 are respectively provided in the bottom wall 38 at positions facing the two locking claws 46 of the right wall 37d and the two locking claws of the left wall 37c.

As shown in FIG. 3, the attachment structure 36 for attaching the display setting device body 23 to the housing 24 includes a right attachment plate 33 and a left attachment plate 34 attached to the left and right sides of the display setting device body 23, and the housing 24. The claw 46 and the stopper 47 provided in the left wall 37c and the right wall 37d, the through hole 52 of the bottom wall 38, and the like.
The right mounting plate 33 and the left mounting plate 34 are each formed of a plate made of a conductive material such as metal. The right mounting plate 33 and the left mounting plate 34 according to this embodiment have the same structure. Therefore, in the following, the configuration of the right mounting plate 33 will be described, and the description of the left mounting plate 34 will be omitted by attaching the same reference numerals as those of the right mounting plate 33 in FIG.

  The right mounting plate 33 is formed by bending a metal plate having a plurality of functional parts described later into a predetermined shape. As shown in FIG. 6, the plurality of functional units include a base 61 formed long in the left-right direction in FIG. 6, and frame-like elastic pieces 62 provided at both ends in the longitudinal direction of the base 61, These are a first support plate 63 provided inside each of the elastic pieces 62 and a second support plate 64 positioned between the pair of elastic pieces 62.

The base 61 is a portion attached to the metal case 32 of the display setting device main body 23. The longitudinal direction of the base 61 shown in FIG. 6 is the vertical direction of the display setting device 21. Holes 65 through which the fixing screws 35 (see FIG. 5) are passed are formed at both ends of the base 61.
The elastic piece 62 includes a pair of arm portions 66 and 66 extending rearward (downward in FIG. 6) from the base portion 61, and a locking portion 67 connecting the rear ends of these arm portions 66. The distance between the pair of arm portions 66 is wider than the vertical width of the locking claw 46. As shown in FIG. 4, the arm portion 66 is provided at a position along the inner surface of the right wall 37 d in the assembled state in which the display setting device main body 23 is attached to the housing 24.

The locking portion 67 is bent in the same direction as the front surface 46 a of the locking claw 46 with respect to the pair of arm portions 66. The locking portion 67 according to this embodiment is inclined more greatly than the front surface 46 a of the locking claw 46.
Further, as shown in FIG. 4, the locking portion 67 is positioned so as to overlap the rear surface 46 b of the locking claw 46 and between the protrusion 51 of the stopper 47 and the right wall 37 d in the assembled state described above. Thus, it is provided at the tip of the arm portion 66. That is, the locking part 67 is locked to the locking claw 46 in the assembled state. Hereinafter, the position of the locking portion 67 locked to the locking claw 46 is simply referred to as “locking position”. The locking portion 67 positioned at the locking position faces the through hole 52 formed in the bottom wall 38 of the housing 24.

  A gap having a predetermined width is formed between the locking portion 67 and the protrusion 51 of the stopper 47. The dimension of this gap is a dimension in which the locking part 67 can move from the protruding end of the locking claw 46 to the center part side of the housing 24 (the locked state is eliminated). The movement of the locking portion 67 is realized by bending the pair of arm portions 66. In other words, the elastic piece 62 is elastically deformed between the locking position 67 (refer to FIG. 4) and the release position (refer to FIG. 9) where the locking section 67 is separated from the protruding end of the locking claw 46. Is possible. When the elastic piece 62 further moves in the same direction after reaching the release position, the locking claw 46 comes into contact with the protrusion 51 of the stopper 47, and further movement of the elastic piece 62 is restricted. Therefore, the stopper 47 restricts the movement of the locking portion 67 from the release position described above to the side opposite to the locking position.

As shown in FIGS. 4 and 6, the first support plate 63 is bent toward the center of the housing 24 so as to be perpendicular to the base 61 (in parallel with the bottom wall 38). ing. As shown in FIG. 7, the first support plate 63 holds the printed circuit board 25 in the front-rear direction in cooperation with the rib 41 of the housing 24 in the assembled state described above.
The second support plate 64 is formed by being bent in the same manner as the first support plate 63. However, as shown in FIG. 4, the second support plate 64 is positioned on the front side (upper side in FIG. 4) than the first support plate 63. In this embodiment, the second support plate 64 corresponds to the “support plate” in the present invention.

  The printed circuit board 25 is overlaid on the second support plate 64 via an elastic member 71. The elastic member 71 can be formed by, for example, a conductive gasket. The elastic member 71 is compressed by being sandwiched between the second support plate 64 and the printed circuit board 25 in the assembled state described above. As shown in FIG. 3, a ground electrode 72 is formed at a portion of the printed board 25 that overlaps the elastic member 71. For this reason, the display setting device main body 23 and the printed board 25 are electrically connected via the right mounting plate 33 and the left mounting plate 34 having the second support plate 64 and the elastic member 71.

  In order to assemble the display setting device 21 configured as described above, first, the connectors 26 and 27 and other parts (not shown) are assembled to the housing 24, and the printed circuit board 25 is inserted into the housing 24. To do. Then, as shown in FIG. 3, the display setting device main body 23 is opposed to the opening of the housing 24, and the right mounting plate 33 and the elastic piece 62 of the left mounting plate 34 attached to the display setting device main body 23 are housed. The body 24 is inserted into the housing 24 along the left wall 37c and the right wall 37d.

  As shown in FIG. 8, when the protective glass 31 of the display setting device body 23 approaches the opening 24 a of the housing 24, the locking portion 67 at the tip of the elastic piece 62 contacts the front surface 46 a of the locking claw 46. Thus, the elastic piece 62 is bent. In this state, when the display setting device main body 23 is further inserted into the housing 24 and the protective glass 31 is fitted into the groove 39a provided in the flange 39 of the housing 24, as shown in FIG. 67 passes over the locking claw 46 and contacts the rear surface 46 b of the locking claw 46. Thus, the display setting device main body 23 is attached to the housing 24 by the locking portion 67 being locked to the locking claw 46.

  On the other hand, in order to remove the display setting device main body 23 from the casing 24, the elastic piece 62 is elastically deformed by pushing the locking portion 67 toward the center of the casing 24 with the elongated tool 81 as shown in FIG. . The tool 81 is inserted into the housing 24 through the through hole 52 that is opened in the bottom wall 38 of the housing 24. When the locking portion 67 is pushed by the tool 81, the locking portion 67 moves to the release position shown in FIG. In this state, the display setting device main body 23 is pulled forward from the housing 24 by pulling the display setting device main body 23 forward with respect to the housing 24.

Since the locking portion 67 of the elastic piece 62 and the locking claw 46 are separated from the through hole 52 of the bottom wall 38 by a predetermined distance L (see FIG. 4), the locking portion 67 and the locking claw 46 are easily visible from the outside of the housing 24. It is not possible. For this reason, a third party who does not know the mounting structure 36 of the display setting device main body 23 cannot remove the locking portion 67.
Since the locking portion 67 is thus separated from the bottom wall 38 by the distance L, the locking portion 67 can be positioned so that static electricity cannot be discharged from the through hole 52 of the bottom wall 38 toward the locking portion 67. it can.

Further, the side wall 37 (the upper wall 37a, the lower wall 37b, the left wall 37c, and the right wall 37d) of the housing 24 is substantially free from a static electricity discharge path because there is no hole to be a discharge path. It becomes the shield part 43.
Therefore, according to this embodiment, the display setting device main body 23 is attached to the casing 24 by the mounting structure 36 that cannot be disassembled at a place other than the factory, and the display setting device 21 is provided with high resistance to static electricity. can do.

  The elastic piece 62 according to this embodiment includes a locking position where the locking portion 67 is locked by the locking claw 46 and a locking state, and the locking portion 67 is separated from the locking claw 46 and locked. It can be elastically deformed between the release position where the problem is resolved. The housing 24 includes a stopper 47 that restricts the movement of the locking portion 67 from the release position described above to the side opposite to the locking position.

For this reason, when the locking portion 67 is excessively pressed when the locking portion 67 is pushed by the tool 81 and removed from the locking claw 46, the locking portion 67 hits the protrusion 51 of the stopper 47 and moves further. I can't do that.
Therefore, the elastic piece 62 can be prevented from being excessively bent and damaged.

  A right mounting plate 33 and a left mounting plate 34 made of a conductive material are fixed to the side portion of the display setting device main body 23 according to this embodiment so as to protrude toward the bottom wall 38. The elastic piece 62 is formed integrally with the right side mounting plate 33 and the left side mounting plate 34. A second support plate 64 extending in parallel with the bottom wall 38 between the engaging portion 67 of the elastic piece 62 and the base portion 61 attached to the display setting device main body 23 in the left attachment plate 34 and the right attachment plate 33. Is provided.

The printed board 25 is overlaid on the second support plate 64 via an elastic member 71 having conductivity. The display setting device main body 23 and the printed circuit board 25 are electrically connected via the right mounting plate 33, the left mounting plate 34, and the elastic member 71.
For this reason, since it becomes possible to electrically connect the display setter main body 23 and the ground circuit (not shown) of the printed circuit board 25, resistance to static electricity is further increased.

The housing 24 can be formed as shown in FIG.
A number of ventilation holes 91 are formed in the lower wall 37b of the housing 24 shown in FIG. Although not shown in FIG. 10, a large number of air holes 91 are formed on the upper wall 37a of the housing 24 in the same manner as the lower wall 37b. These vent holes 91 are formed at a predetermined distance L from the metal case 32 of the display setter body 23, the mounting plates 33 and 34, and the conductive portion of the printed circuit board 25.
Thus, even if the vent holes 91 are formed in the upper wall 37a and the lower wall 37b, these vent holes 91 are not holes that serve as a discharge path, and thus do not affect the resistance to static electricity.
Further, holes 92 and 93 for inserting a recording medium are formed in the left wall 37c shown in FIG. Even if the holes 92 and 93 for inserting the recording medium serve as a discharge path, the right wall 37d portion can be highly resistant to static electricity.
