SIGNAL TRANSMISSION DEVICE, ELECTRONIC APPARATUS, AND SIGNAL TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electronic apparatus having a hinge structural body so as to be folded freely, which provides signal interface between cases without having electric wiring.

SOLUTION: An operation part case 910 and a display part case 930 of a mobile phone 900A are connected through a hinge structural body 1001 so as to be folded freely. The hinge structural body 1001 includes two waveguides 1012 and a waveguide 1014 to be aligned with a folding rotation axis and a coaxial core. The waveguide 1012 includes a transmission channel connection part 1108 having an antenna structure disposed at the end part thereof while the waveguide 1014 includes a transmission channel connection part 1208 having an antenna structure at the end part thereof. Each end part of the waveguide 1012 and the waveguide 1014 is disposed with a terminal member 1090 or a wave absorber 1092 as needed. A radio communication signal channel having waveguide structure is provided at the connection part between the two cases in order to carry out radio communication in the radio wave frequency band between transmission and reception parties.
