Claims

[Scope of Claim for Utility Model Registration] (1) In an antenna structure that includes a built-in antenna formed of a metal plate having a flat area inside the housing, and a rod-shaped external antenna attached so as to be able to be stored inside the housing, An antenna switching structure characterized by comprising a switch mechanism that is driven by an operation of inserting and removing the rod-shaped antenna to switch between the built-in antenna and the external antenna. (2) The antenna switching structure according to claim 1 of the utility model registration, characterized in that in the rod-shaped external antenna, only the part that operates the switch mechanism is a rigid body, and the other element parts are of a flexible type. (3) The switch mechanism includes a plurality of fixed metal contact pieces and a plurality of spring metal contact pieces, a plastic case that holds the fixed and spring contact pieces, and a metal case that covers the outer surface of the plastic case. An antenna switching structure according to claim 1 or 2 of the utility model registration claim characterized by: (4) Utility model registration claims 1 to 3, characterized in that a printed circuit board on which an antenna matching circuit is printed is directly attached to one end of the fixation of the switch mechanism and the spring contact piece. antenna switching structure. (5) A utility model characterized in that the rigid body part of the rod-shaped external antenna is provided with a resin flange part for movable a spring contact piece of a switch mechanism and a metal flange part for movable the spring contact piece to obtain an electrical contact point.
