PROBLEM TO BE SOLVED: To provide a biological information detection device capable of quickly correcting the displacement of the position where biological information for a path of light emitted to an organism can be normally acquired.SOLUTION: Corresponding to each divided region of a surface of light-blocking part 113, a biological information detection device 101 causes a light emitting part 111 to emit light li in a state that other regions excepting each divided region of the surface is light-blocked by the light blocking part, and acquires a signal indicating the intensity of the light received by a light receiving part 112. Then, the biological information detection device determines a point where the intensity of the light is maximum as the best measurement point from the intensity of the light corresponding to each divided region. The biological information detection device determines the direction of displacement of the position of an organism org with respect to the light path on the basis of the result of comparison between the best measurement point and a central point of the light blocking part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】生体に発する光の経路に対する生体情報が正常に取得できる位置のずれを迅速に修正することができる生体情報検出装置を提供する。【解決手段】生体情報検出装置101は、遮光部113の面を分割した各分割領域に対応して、その面のうち各分割領域を除く他の領域を遮光部によって遮光した状態で発光部111から光liを発させて、受光部112が受けた光の強さを示す信号を取得する。次に、生体情報検出装置は、各分割領域に対応する光の強さから、光の強さが最も大きいところが最良測定点であると判定する。そして、生体情報検出装置は、最良測定点と遮光部の中心点との比較結果に基づいて、光の経路に対する生体orgの位置のずれの方向を判定する。【選択図】図1
