Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a longitudinal side view and an external front view of an embodiment of an antenna mechanism according to the present invention,
FIG. 2A shows a state where the antenna is housed, and FIG. 2B shows a state where the antenna is extended. In both figures,
The mobile phone 10 is provided with a rectangular display unit 12 at a slightly upper part on the front side of the housing 11, and a button group 15 such as a speaker unit 13, a microphone unit 14, and a numeric button used for a dial or the like. The antenna 17 is provided on the surface.
Are provided in the housing 11 so as to be housed or pulled out.

Further, in this embodiment, the button group 15
The call button 16 which is one of the buttons in FIG.
As shown in the enlarged view of (C), a projection (push button) 16a is planted on the back surface, and the projection 16a can be loosely fitted into a through hole 11a formed in the housing 11. The feature is that it is done. The call button 16 is made of, for example, a flexible member such as rubber. When pressed, the upper part of the call button is slightly recessed, and the tip of the projection 16a penetrates the through hole 11a. When the pressing of the talk button 16 is released, the tip of the projection 16a is automatically returned to the through hole 11a. It is needless to say that when the call button 16 is pressed, the press information is input to a predetermined circuit.
