PROBLEM TO BE SOLVED: To reduce the electric power consumed at light emitting elements in measurement of multiple pieces of biological information.SOLUTION: A biological information measuring apparatus 10 includes a light emitting element LD1 and a light emitting element LD2 that emit light having mutually different wavelengths, and a light receiving element 3. The biological information measuring apparatus 10 controls the periods of light emission from the light emitting elements LD1 and LD2 such that the number of light emission from the light emitting element LD2 is smaller than the number of light emission from the light emitting element LD1 per unit time for the light emitting elements LD1 and LD2. The biological information measuring apparatus 10 measures multiple pieces of biological information based on a frequency spectrum with respect to the amount of light received at the light receiving element 3 from the light emitting element LD1 and on the respective amounts of light received at the light receiving element 3 from the light emitting element LD1 and the light emitting element LD2.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】複数の生体情報を測定する際に、発光素子で消費される電力を削減する。【解決手段】互いに波長の異なる光を照射する発光素子LD1及び発光素子LD2と、受光素子3とを備える生体情報測定装置10は、発光素子LD1及び発光素子LD2の単位時間あたりの発光素子LD2の発光回数が発光素子LD1の発光回数より少なくなるように、発光素子LD1及び発光素子LD2の発光期間を制御し、受光素子3で受光した、発光素子LD1による光の受光量に対する周波数スペクトル、並びに、受光素子3で受光した、発光素子LD1による光の受光量及び発光素子LD2による光の受光量から、複数の生体情報を測定する。【選択図】図8
