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.

In this way, the base member 17 can be left attached to the bottom of the lower case 3 not only when it is placed on a table but also when it is hung on a wall, so that the extra length of the line cord 25 can be accommodated in the groove 20 of the base member 17. By storing the parts, the extra length part of the line cord 25 can be processed for both tabletop and wall hangings. Further, in this process, since the base member 17 used at the time of tabletop is used as it is, the number of parts does not increase, and therefore the structure is simplified and the manufacturing cost can be reduced.

In the present embodiment, one end of the base member is detachable from the bottom of the housing so that the display angle of the display portion can be changed by the support member. If it is pivotally attached to the bottom but the display angle of the display unit does not need to be changed, the base member may be simply attached to the bottom of the housing without being pivotally attached, and in that case, the support member is also unnecessary. .

[0023]

As described above, according to the present invention, since the line cord is not housed inside the housing, the structure is not complicated and the housing does not become large, and the wall cord is It can be used for both purposes on the table. Further, since the base member used at the time of tabletop can also be used, the number of parts does not increase, so that the structure can be simplified and the manufacturing cost can be reduced. Further, the work of inserting the line cord into the groove is easy, and the line cord can be reliably prevented from coming out of the groove.
