Abstract

It is an object of the invention to provide a portable wireless apparatus capable of maintaining high quality of a communication in various using configurations obtained by a two-axis hinge mechanism. A portable wireless apparatus (100) having a two-axis hinge portion includes a first antenna (102) which is suitable for a talking state and a second antenna (104) which is suitable for a waiting state. The first antenna (102) or the second antenna (104) is selected based on a result of opening/closing detection decided from an angle α of a first axis (106) and the result of opening/closing detection decided from an angle β of a second axis (107). Consequently, it is possible to select either of the antennas which is not influenced by hands or fingers of a user.

Claims7

Dependent claims

A portable wireless apparatus having a hinge portion for opening/closing and rotatably supporting a first housing with respect to a second housing and serving to feed power between an antenna provided in the first housing or the second housing and a built-in wireless circuit, comprising:

an opening/closing detector for detecting an opening/closing state of the first housing, the first housing opening and closing about an opening/closing axis of the hinge portion;
a rotation detector for detecting a rotation state of the first housing, the first housing rotating about a rotating axis of the hinge portion perpendicular to the opening/closing axis of the hinge portion;
and
a selector selecting any of a plurality of antennas provided in at least one of the first housing and the second housing which is to be operated based on the opening/closing state and the rotation state,
wherein the antennas comprise a first antenna and a second antenna, the first antenna provided on an end of the first housing opposite the hinge portion and the second antenna provided on an end of the second housing adjacent the hinge portion side.
