Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as a telephone used both on a table and on a wall.

[0002]

2. Description of the Related Art For example, when a telephone is used on a desk, a base member having a substantially triangular shape in a side view is attached to a bottom portion of a housing in order to improve operability of dial buttons and to make a display device easy to see. The phone surface is angled with respect to the horizontal. Also, as another structure, a supporting member is pivotally attached to the bottom of the housing, and this supporting member is leaned between the bottom of the housing and the tabletop so that the surface of the telephone is angled with respect to a horizontal surface. ing.

[0003]

However, these base members or supporting members are not necessary when the telephone is wall-mounted, and therefore, it is necessary to remove them from the housing, which takes time and effort for removal.
Further, the removed base member and supporting member may be lost, and there is a problem that the base member and the supporting member cannot be used next time on a table.

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 a tabletop and a wall mount and to prevent loss of tabletop equipment. It is to provide a tabletop / wall hanging structure for equipment.

[0005]

In order to achieve this object, a desk-top / wall-hanging structure for an electronic apparatus according to the present invention has a convex portion formed with an engaging portion for engaging a wall-hanging member at the bottom of a housing. A base member attached to the bottom of the housing and on which the housing is placed is provided, and a hollow portion capable of accommodating the convex portion of the housing is formed in the base member, and the base member and the convex portion have substantially the same height. To form. So at tabletop,
The convex portion does not hinder the use on a table, and the base member does not hinder the wall-mounted use even when the base member is left attached to the housing when the wall is hung.

Has been.

Next, a case where the telephone having such a configuration is used on a desk will be described. First, the pivot portion 1 of the support member 15
5a to the holding piece 3b through the opening 11d as shown in FIG.
While elastically deforming the
The pivot 15a is pivotally attached to the bearing 11e. Next, as shown in FIG. 3, the convex portions 18a, 18a of the base member 17 are
Openings 10a, 1 of the shaft bearings 10, 10 of the lower case 3
The base member 17 is rotatably supported by the bottom portion of the lower case 3 via the shaft bearings 10 and 10 by being engaged with a bearing recess (not shown) from 0a.

By rotating the base member 17 so that the base member 17 is brought into close contact with the bottom portion of the lower case 3, and as shown in FIG. 6, the protrusion 18d of the base member 17 is engaged with the elastic engagement piece 3a of the lower case 3. Lower case 3 of base member 17
The close contact with the bottom of the is maintained. At this time, the dowel 23d of the holding member 23 of the base member 17 is supported by the support member 15
Since it engages with the surface of the support member 15, the rotation of the support member 15 about the pivotal portion 15a is restricted, and as shown in FIG. The parts 11 and 12 and the support member 15 are accommodated.
Since the base member 17 assembled to the bottom portion of the lower case 3 in this manner and the protrusions 11 and 12 are formed at substantially the same height, by mounting the base member 17 on the table 27, It becomes possible to use the telephone 1 on the desk.

When the display device 5 of the telephone 1 is difficult to see or the function buttons 6 and dial buttons 7 are difficult to operate and the display angle of the display device 5 is changed, as shown in FIG. The protrusion 18d of the base member 17 is disengaged from the elastic engagement piece 3a of the case 3, and the lower case 3
Grasp the X-direction end by hand and lift it. Bearing member 1
5, the engagement of the base member 17 with the dowel 23d is released and the regulation of the rotation is released.
The pivot 15a pivotally supported by e is rotated in the counterclockwise direction in the drawing around the pivot. When the engagement portion 15b of the support member 15 is engaged with the engagement recess 23a, the elastic engagement piece 15c elastically deforms, so that the support member 15 is firmly fixed to the bearing portion 11e and the engagement recess 23a by this elastic deformation. The supporting device 15 holds the display device 5 of the telephone 1 at the display angle α. When the display angle α of the display device 5 is also insufficient, the end portion of the lower case 3 is further lifted from the state of FIG. 8, the supporting member 15 is rotated clockwise, and the engaging portion 15b is changed to the state shown in FIG. As shown, another engagement recess 2
By engaging with 3b, the display angle can be set to β.

Next, a case where the telephone 1 is hung on a wall for use will be described. As described in the case of using on the above-mentioned table, as shown in FIGS. 4 and 6, the base member 17 is brought into close contact with the bottom portion of the lower case 3, and the elastic engaging piece 3 a of the lower case 3 is attached to the base member 17. By engaging the protrusion 18d, the convex portions 11 and 12 of the lower case 3 and the support member 15 are accommodated in the hollow portion 21 of the base member 17. In this state, as shown in FIG. 7, the convex portion 1 of the lower case 3 is attached to the head portion 31 a of the wall hanging member 31.
The opening 13 of the die-cutting hole 13a of the retaining portions 13 of 1 and 12
When b is engaged and the telephone 1 is moved downward in the figure, the head portion 31a is engaged between the retaining portion 13 and the cutout piece 11a and engages with the retaining portion 13.

At this time, as described above, the projections 11 and 12 of the lower case 3 and the walls 18 and 1 of the base member 17 are enclosed.
Since the heights of 9 are substantially the same, the base member 1
Even when 7 is attached to the bottom of the lower case 3, it does not hinder the engagement of the retaining portions 13 of the protrusions 11 and 12 with the head 31a of the wall-hanging member 31. Thus, even when the telephone 1 is hung on a wall and used, the base member 17 can be left attached to the lower case 3 without the need to remove the base member 17, and before the next use on the tabletop. There is no risk of losing the member 17. Further, when the telephone 1 is attached to the wall-hanging member 31, the protrusion 18 of the base member 17
Since d is engaged with the elastic engagement piece 3a of the lower case 3, the state in which the base member 17 is in close contact with the bottom portion of the lower case 3 is maintained, and the workability of mounting is improved.

In this embodiment, one end of the base member 17 is detachable from the bottom of the lower case 3 so that the support member 15 can change the display angle of the liquid crystal display device 5. The other end of 17 is pivotally attached to the bottom of the lower case 3, but if it is not necessary to change the display angle of the liquid crystal display device 5, the base member 17 is simply attached to the bottom of the lower case 3 without pivoting. However, in that case, the support member 15 is also unnecessary.

[0021]

As described above, according to the first and second aspects of the present invention, it is possible to save the labor of removing the base member when using it on a table by hanging it from the table, and to use it on the table next time. There is no risk of losing the base member.

According to the third aspect of the invention, since the base member is held in close contact with the bottom surface of the housing when the electronic device is mounted on the wall-hanging member, the workability of mounting is improved.
