【Task】 When acquiring biological information with a multi-axis pressure sensor, it is difficult to both fix the device body to the person to be measured and to mount the sensor at the appropriate position on the person to be measured, and to acquire the biological information with high accuracy. It was an obstacle. [Solution] A sensor-dedicated member different from the member that fixes the apparatus main body when the multiaxial pressure sensor for acquiring biological information is attached to the measurement subject is provided. [Selection diagram] Figure 1【課題】多軸圧力センサーで生体情報を取得する際に、装置本体を被測定者に固定することとセンサーを被装着者の適切な位置に装着することの両立が困難で、精度良く生体情報を取得する妨げとなっていた。【解決手段】生体情報取得用の多軸圧力センサーを被測定者に装着する際に装置本体を固定する部材とは別のセンサー専用部材を設ける。【選択図】図１
