PROBLEM TO BE SOLVED: To measure biological information of a subject continuously for a long time without trouble while the subject is prevented from burn at low temperature.SOLUTION: A sensor 110 includes a light emitting part 112 and a light receiving part 111 which are composed to mount on a first site of a subject detachably and the light with various wavelengths is emitted from the light emitting part 112 and transmitted through the first site, and reflected on the first site and detected at the light receiving part 111. A sensor 120 has a light emitting part 122 and a light receiving part 121 which are composed to mount on a second site of the subject detachably, and the light with various wavelength is emitted from the light emitting part 122 and transmitted through the second site, and reflected on the second site and detected at the light receiving part 121. A light emission drive circuit 137 drives the light emitting parts 112, 122 selectively and make them emit. CPU 138 introduces the biological information based on a first detected result obtained by the light receiving part 111 while the light emitting part 112 is driven to emit, and the biological information is introduced based on the second detected result obtained by the light receiving part 121 while the light emitting part 122 is driven to emit.COPYRIGHT: (C)2011,JPO&INPIT【課題】生体情報の長時間連続測定を、手間をかけずに被検者の低温やけどを予防しつつ行うこと。【解決手段】センサ110は、被検者の第1の部位に装着可能に構成された発光部112と受光部111とを有し、発光部112から発光されて第1の部位を透過しまたは第1の部位にて反射した複数波長の光を受光部111にて検知する。センサ120は、被検者の第2の部位に装着可能に構成された発光部122と受光部121とを有し、発光部122から発光されて第2の部位を透過しまたは第2の部位にて反射した複数波長の光を受光部121にて検知する。発光駆動回路137は、発光部112、122を選択的に駆動して発光させる。CPU138は、発光部112の発光駆動中は、受光部111にて得られる第1の検知結果に基づいて生体情報を導出し、発光部122の発光駆動中は、受光部121にて得られる第2の検知結果に基づいて生体情報を導出する。【選択図】図1
