Since the engaging portion 18 and the engaging portion 2212 are provided in both the housing 10 and the stand 20, when the curved surface portion 16 </ b> B of the housing 10 is about to come out of the stand 20, the engaging portion 18 and the engaging portion 2212. And can be prevented from falling.

  Therefore, since it is not necessary to increase the height of the stand 20 to prevent the fall, the stand 20 does not become too large. Moreover, it can be supported in a vertically placed state without impairing the design of the casing 10 in which one side of the bottom surface portion is formed into a curved surface as in this embodiment. Furthermore, the space of the stand 20 can be saved when the stand 20 is not used.

  Moreover, since the housing | casing 10 can be installed only by mounting on the stand 20, extra work, such as stopping with a screw or a hook, is not required. That is, it has a simple configuration in which the housing 10 naturally engages with a force that falls due to gravity. Therefore, since various members for installing the housing 10 on the stand 20 are not necessary, there is no risk of losing various members, and the device can be provided at low cost. Further, the housing 10 can be easily taken out of the stand 20 at any time.

Further, since the corner portion 16A of the housing 10 and the corner portion 224A of the stand 20 and the curved surface portion 16B of the housing 10 and the curved surface portion 224B of the stand 20 have substantially the same shape, the housing 10 is attached to the stand 20. When placed, the housing 10 is stable and can be reliably supported.
Furthermore, since the stand 20 has a truncated cone shape, the housing 10 can be supported more stably.

Therefore, when the power switch 111 or various switches 112 of the housing 10 are pressed, the button operation or the like can be reliably performed without the housing 10 moving.

[Modification of Embodiment]
In addition, this invention is not limited to embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.
For example, in this embodiment, the shape is adapted to fit the curved surface portion 16B of the housing 10 from the protruding portion 2211 of the stand 20 to the curved surface portion 224B, but as shown in FIG. You may provide only in a part of center part of the surface 221. FIG. Further, the shape of the mounting surface 221 may not be a shape that matches the shape of the bottom surface portion 12 and the side surface portion 14B of the housing 10. In this case as well, the engaging portion 18 of the housing 10 and the engaging portion 2212 of the stand 20 can be engaged to prevent overturning.

In the present embodiment, the casing 10 has a curved surface only on one curved surface portion 224B. However, as shown in FIG. 6, the housing 10 may have a curved surface on both corners. In this case, it is preferable that a recess 123 is formed in the housing 10 so as to be fitted with a protrusion 2211 provided at a substantially central portion of the placement surface 221. In this case, the wall surfaces on both sides of the protruding portion 2211 provided on the stand 20 become the engaging portions 2212 and the engaging portions 2213, and the wall surfaces on both sides of the concave portion 123 of the housing 10 become the engaging portions 1231 and the engaging portions 1232.
Therefore, the engaging portion 2212 of the stand 20 and the engaging portion 1231 of the housing 10 are engaged, and the engaging portion 2213 of the stand 20 and the engaging portion 1232 of the housing 10 are engaged to each other. The body 10 can be prevented from falling.

  Further, in the present embodiment, the engaging portion 18 of the stand 20 is protruded from the placement surface 221 and engaged with the housing 10, but a recess may be formed on the placement surface. In this case, it is necessary to form a convex part that fits into the concave part on the casing. If it is such a structure, when the housing | casing is installed in a stand, the recessed part of a stand and the convex part of a housing | casing will fit. When the casing is about to fall, the concave portion and the convex portion can be engaged with each other to prevent the fall.

The inner wall portion 23 is provided with a placement portion 24 that is parallel to the shape of the placement portion 22 and is higher than the placement portion 22, and is rotatably attached to the outer wall portion 21. When changing the height of the mounting part 22 which opposes, the inner wall part 23 is rotated so that the mounting part 24 may come to the position of one mounting part 22. FIG. Then, the case 10 is placed on the stand 20 so that the stand 20 is sandwiched between the ribs 121 and 122 of the case 10. If the front surface part 11 is installed on the mounting part 24 side, it can be installed upward. In addition, when it is desired to use the opposite mounting portions 22 at the same height, the mounting portions 24 are rotated to a position where they are hidden by the outer wall portion 21.
As shown in FIG. 8, the outer wall portion 21 and the inner wall portion 23 can be easily attached simply by covering the inner wall portion 23 with the outer wall portion 23 when the height does not need to be changed. 21 and the inner wall part 23 can also be used separately.

Furthermore, as a structure whose height can be adjusted, a structure as shown in FIGS. 9 and 10 may be used.
In FIG. 9, a pair of placement portions 22 and another pair of placement portions 25 are provided on the outer wall portion 21 of the stand 20. If the mounting portions 22 have the same height and the mounting portions 25 have different heights, the height and inclination of supporting the housing can be changed by simply changing the orientation of the stand 20.
Further, as shown in FIG. 10, a pair of mounting portions 22 and 26 may be provided on the upper and lower portions of the outer wall portion 21 of the stand 20, respectively. If the mounting portion 22 has the same height and the mounting portion 26 has a different height, the height and inclination can be changed by turning the stand 20 upside down.

  Further, in the present embodiment, the ribs 121 and 122 of the housing 10 are provided at positions where they contact the outside of the stand 20, but the ribs 121 and 122 may be provided so as to be able to contact the stand 20, It may be provided so as to contact the inside of the stand 20. Further, when the casing 10 is used at an angle, one of the ribs 121 and 122 is brought into contact with the outside of the stand 20 and the other is placed inside the stand 20 in that it can be stably supported. It is preferable to provide so that it may contact | abut.

  Furthermore, the shape of the stand 20 is not limited to a truncated cone shape, and may be a cylinder or a rectangular tube. Moreover, if the mounting part is formed, it may be in a block shape and can be appropriately selected in consideration of the design when combined with the housing.

[Effect of the embodiment]
As described above, even if the casing has a curved corner, it can be reliably supported and can be prevented from falling.
In addition, the housing naturally engages with the force of falling due to gravity. When installing the housing on the stand, it is only necessary to place the housing on the stand. You can also.
