PROBLEM TO BE SOLVED: To reduce the size of a device (relay unit 3) carried by a subject.SOLUTION: Radio signals from a capsule-type endoscope, which are received through receiving antennas A1-An electrically connected to the relay unit 3, are subjected to frequency conversion processing in a frequency conversion unit 35, and then wirelessly relayed to an external device 4 out of the subject 1 through a transmission unit 37, whereby recording on a recording device provided in the external device and display on a display device can be performed. Accordingly, arrangement of a high-capacity recording device for recording all image data in the relay unit 3 is dispensed with.COPYRIGHT: (C)2012,JPO&INPIT【課題】被検者が携帯する装置(中継ユニット3)の小型化を図ること。【解決手段】中継ユニット3に電気的に接続された受信アンテナA1~Anを介して受信したカプセル型内視鏡からの無線信号に対して、周波数変換部35で周波数変換の処理を施した後に、送信部37から被検体1外部の外部装置4に無線で中継して、外部装置に設けた記録装置への記録および表示装置への表示を可能にすることで、中継ユニット3に画像データを全て記録する大容量の記録装置の配置が不要となる。【選択図】図2
