PROBLEM TO BE SOLVED: To provide a biological information acquisition device which has a vibration sensor detecting vibration including a subjects heartbeat and accurately calculates the subjects biological information.SOLUTION: Vibration sensors (3A-3C) are arranged on a chair (5) where a subject sits on to acquire the subjects biological information according to vibration signals based on the subjects heartbeat detected with the vibration sensors (3A-3C). The vibration sensors (3A-3C) have at least vibration sensors (3A, 3B) arranged on a backrest part (5b) of the chair (5) and a vibration sensor (3C) arranged on a seat part (5s) of the chair (5).COPYRIGHT: (C)2015,JPO&INPIT【課題】被験者の鼓動を含む振動を検出する振動センサを備えた生体情報取得装置において、被験者の生体情報を精度良く算出する。【解決手段】 被験者が座る椅子(5)に振動センサ(3A~3C)が配置され、その振動センサ(3A~3C)が検出した被験者の鼓動に応じた振動信号に基づいて、被験者の生体情報を取得する。上記振動センサ(3A~3C)は、少なくとも、上記椅子(5)の背もたれ部(5b)に配置された振動センサ(3A,3B)と、上記椅子(5)の座部(5s)に配置された振動センサ(3C)とを備える。【選択図】図1
