  • Publication number: 20190298225
    Abstract: A biological information measurement apparatus comprises: a spectrometer; a housing that contains the spectrometer and includes a surface on which a measurement target is to be placed, and an aperture portion through which light illuminating the measurement target placed on the surface and light reflected from the measurement target are to pass; and a shutter member that can move between a first position of opposing the aperture portion of the housing and a second position of retreating from the first position of opposing the aperture portion, the shutter member including a white reference surface. If the shutter member is at the first position, the spectrometer performs calibration using the white reference surface. If the shutter member is at the second position, the aperture portion and the measurement target oppose each other, and the spectrometer colorimetrically measures the measurement target.
