PROBLEM TO BE SOLVED: To solve such the problems that a large number of components are used and a lot of time is needed for processing each of information obtained from a plurality of light receiving elements, since the plurality of light receiving elements and light emitting elements are provided and they are arranged near the artery with a high probability in a pulse wave detector.SOLUTION: The pulse wave detector includes one light receiving element and the plurality of light emitting elements having prescribed positional relation with one another. Thus, since one of the light emitting elements is arranged near the artery with the high probability and detection accuracy does not decline no matter from which light emitting element the light is detected by the light receiving element, there is provided the pulse wave detector which is capable of accurately detecting pulse waves, has the small number of components, consumes little power, and processes the information in a short time.COPYRIGHT: (C)2013,JPO&INPIT【課題】脈波検出装置においては、複数個の受光素子と発光素子を備え、これらを高い確率で動脈付近に配置できるようにしている。このため、部品数が多いうえに、複数個の受光素子から得た情報の各々を処理する時間を多く要する。【解決手段】脈波検出装置は、一つの受光素子と所定の位置関係にある複数個の発光素子を備える。これにより、高い確率でいずれかの発光素子を動脈付近に配置でき、いずれの発光素子からの光を受光素子で検出しても検出精度が低下することはないため、精度良く脈波検出ができ、部品数が少なく、消費電力が少なく、情報処理の時間の短い脈波検出装置を提供できる。【選択図】図1A
