Media case and circuit pattern sheet

摘要

An object of the present invention is to provide a media case and a circuit pattern sheet with a simple configuration allowing highly dense collection and reliable recognition of housed disk media.

<Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">In order to attain the object, a media case 1 of the present invention can house disk media 50 provided with an RFID tag (not illustrated in the drawing). This media case 1 includes an antenna element 51a being formed on its back plane to exchange an electromagnetic wave signal with the outside of the media case 1; a waveguide line 52a formed in the vicinity of its center therethrough along the disk media 50 from the antenna element 51a to guide high-frequency signals representing the electromagnetic wave signals to the antenna element 51a; and a resonance element 53a being formed adjacent to this waveguide line 52a and electromagnetically induced by the high-frequency signal.
