Therefore, in consideration of the size of the area for securing the space R and the fact that the first end 2a side of the display housing 2 comes into contact with the installation surface 200, the rotation center position α1 of the hinge shaft 3A2 It is necessary to adjust the amount of deviation from the center position β1 of the hinge cap 3A4 when viewed from the axial direction of the hinge shaft 3A2.

  7 (a) to 7 (c), the left figure shows the state of the first position where the angle between the main body housing 1 and the display housing 2 is 0 °, and the right figure shows the main body. The state of the 2nd position where the angle | corner which the housing | casing 1 and the display housing | casing 2 make is 135 degrees is shown. FIG. 7 shows the relationship between the rotation center position α1 of the hinge shaft 3A2 and the center position β1 of the hinge cap 3A4 when viewed from the axial direction of the hinge shaft 3A2. However, the relationship between the rotation center position α1 of the hinge shaft 3B2 and the center position β1 of the hinge cap 3B4 when viewed from the axial direction of the hinge shaft 3B2 is the same as that in FIG.

  Further, as shown in FIG. 3, the display housing 2 of the present embodiment has the display housing 2 in the second position with the hinge portion 3 as a rotation axis in a state where the main body housing 1 is installed on the installation surface 200. The first end 2a side is chamfered so that the first end 2a side does not come into contact with the installation surface 200 when the first end 2a is rotated. In the present embodiment, the second position means a position where the angle formed by the main body housing 1 and the display housing 2 is 135 °. Thereby, even if it is a case where the display housing | casing 2 is comprised by the taper shape, the 1st edge part 2a side of the display housing | casing 2 can be made not to contact the installation surface 200. FIG.

  As shown in FIG. 8, the display housing 2 is configured in a tapered shape, and the main body housing 1 is installed on the installation surface 200, and as shown in FIG. It is assumed that the display housing 2 is rotated to the second position. The second position means a position where the angle formed by the main body housing 1 and the display housing 2 is 135 °. In this case, as shown in FIG. 8B, the first end 2a side of the display housing 2 comes into contact with the installation surface 200, and the display housing 2 can be rotated to the second position. become unable. For this reason, in this embodiment, as shown in FIG. 8B, at least a portion 300 where the first end 2a side of the display housing 2 and the installation surface 200 are in contact with each other is chamfered.

For example, if the depth of the concave groove of the foot placement portion 20 is varied to form a region where the depth of the concave groove is deep, the height of the internal space of the main body housing 1 becomes low. A region to be formed is formed. When the height of the internal space becomes low, it becomes impossible to accommodate thick parts inside. For this reason, in order to form the area | region where the depth of a concave-shaped groove | channel is deep and to ensure the height of the internal space of the main body housing | casing 1, the thickness of the main body housing | casing 1 itself will be thickened. End up. On the other hand, since the depth of the concave groove of the foot placement portion 20 is made uniform, an area where the height of the internal space of the main body housing 1 is not formed is not formed. 1 can be reduced in thickness.
