Title:
伝送装置、コンピュータシステムおよび開閉構造体
Document Type and Number:
Japanese Patent JP4598267
Kind Code:
B2
Abstract:
A portable device having a base member and a hingedly attached lid member does not require a signal cable to transmit a high-frequency signal between the base unit and the lid. While the lid of the lap-top PC is closed, a radio device installed in the base unit transmits a high-frequency signal from a first antenna to a second antenna, the signal is then output from a signal cable attached third antenna to the atmosphere. The device structured as described above can transmit the high-frequency signal in a non-contact manner between the antenna of the base unit and the antenna of the lid in such a way that there is no need to provide a signal cable between the base unit part and the lid part.
