Abstract:
1. A communication terminal, comprising: a first casing member, which contains a first printed circuit board having a conductive portion; a second casing member, which contains a second printed circuit board having a conductive portion; a hinge portion, which connects the first casing member to the second casing member so as to freely open and close; and an antenna, which is provided in the second casing member; wherein the hinge portion includes a first rotating member formed by conductive material and a second rotating member formed by the conductive material: wherein the first rotating member serves as an axis for rotating the first casing member and the second casing member in an opposed direction of the first and second casing members; wherein the second rotating member has a first end portion rotatably supported on the first rotating member at right angles to each other and a second end portion away from the first rotating member; wherein the second rotating member serves as an axis for rotating one casing member of the first and second casing members relative to the other casing member of the first and second casing members in a direction perpendicular to the rotating direction in which the first rotating member serves as the axis under a non-opposed state of the first and second casing members; wherein the first casing member holds the second end portion of the second rotating member; wherein the second casing member holds both end portions of the first rotating member; wherein the antenna is provided along in an axis direction of the first rotating member; wherein an end portion of the antenna which is arranged at one end side of the first rotating member is connected to a power feeding portion provided on the second printed circuit board; wherein the second printed circuit board is electrically coupled with the first printed circuit board which is separated with a predetermined interval from the second printed circuit board; and wherein the second printed circuit board is separated from the first rotating member and the second printed circuit board is isolated in direct current at an area near to the both end portions of the first rotating member.
