DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to telephones widely used in homes and offices, and more particularly to telephones for both wall and desk use.

[0002]

2. Description of the Related Art Generally, in this type of wall-mounted / desktop telephone, in order to prevent the handset from dropping and to improve the operability of dial buttons, the lower end of the telephone is separated from the wall when the telephone is mounted on a wall. When used on a desk, the telephone is inclined so that the upper end of the telephone is separated from a desk or the like.

Conventionally, in order to form these two kinds of inclined forms, the upper end side is more often used on a table than the lower end side in a side view, on the precondition that it is used more often than on a wall. As a case structure in which the front part is inclined so as to be higher, it is mounted on a desk or the like as it is without using a bracket or the like on a desk. on the other hand,
When used on a wall, a wall-mounting bracket is attached to the rear surface of the housing so that the lower end in the side view is higher than the upper end with respect to the wall.

[0004]

However, the conventional wall-mounted / desktop telephone described above does not use the wall-mounting bracket when the frequently used table-top is used. It may be lost. For this reason, when changing from the desktop use to the wall use, it is often inconvenient that the user has to purchase a new wall mount bracket. In addition, manufacturers must keep inventory as optional parts for a long time,
There was a problem that management man-hours were required. further,
In order to use it for desktop use, the top end of the housing is raised in advance as a housing structure.
Since the lower end must be made to protrude more than the upper end with the wall-mounting bracket, the amount of protrusion from the wall increases, and thus there is a problem that the pedestrian is likely to come into contact with the body.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to make it possible to easily switch between tabletop use and wall mount use, and Another object of the present invention is to provide a thin wall-mounted / desktop telephone.

[0006]

In order to achieve this object, a telephone according to the present invention comprises two mounting surfaces having different inclinations along the front-rear direction so as to have an approximately isosceles triangle shape in side view. And a flat base member having a mounting portion for mounting the mounting surface of the telephone housing, and a mounting portion for wall-mounting, the base member and the telephone housing. Are assembled integrally, and a positioning fitting portion for the base member is provided between the two mounting surfaces.

[0007]

According to the present invention, the base member is turned upside down, and the base member is mounted on one of the two mounting surfaces, so that the base member can be selected for desktop and wall mounting. Further, according to the present invention, the positioning fitting portion becomes the reversal center of the base member.
