  According to the structure of Patent Document 1, when changing from a state where it can be placed on a horizontal surface such as a desk or floor to a state where it can be placed on a substantially vertical wall, In order to store in the storage portion on the back of the main body, the main body is tilted all the way to the rear, and a simple operation of attaching a dedicated metal fitting is sufficient, so that the usability of the device is improved. However, in the above-described structure, the leg portion remains stored in the storage portion on the back of the main body when installed on a substantially vertical wall surface, so that the main body cannot be tilted by a pivotal support portion that connects the main body and the leg portion. Thus, it is difficult to adjust the angle of the main body when it is installed on a substantially vertical wall surface.

  According to the structure of Patent Document 2, since a hinge portion having a plurality of pivotal support portions is provided between the main body and the leg portion, it is almost vertical from a state where it can be placed on a horizontal surface such as a desktop or floor surface. When changing to a state where it can be installed on the wall surface, the pivot part of the hinge part can be rotated to position the leg part on the back side of the main body without performing the work of attaching and detaching the main body and the leg part. In addition, the angle of the main body can be adjusted by a pivotal support portion interposed between the main body and the hinge portion in a state where the main body is installed on a substantially vertical wall surface. However, since the hinge part interposed between the main body and the leg part is composed of a large number of parts including a plurality of pivot parts, there is a risk that the equipment becomes expensive.
