  • Optical measuring device, malfunction determination system, malfunction determination method, and a non-transitory recording medium storing malfunction
    Patent number: 11169023
    Abstract: An optical measuring device includes a light measurement unit, an acceleration sensor for detecting the acceleration of the optical measuring device, a storage for storing reference data obtained from the light measurement unit by measuring light from a reference object at a first timing and storing the acceleration detected by the acceleration sensor as history information, a first determination unit for determining whether the result of comparison between measurement data obtained from the light measurement unit by measuring light from the reference object at a second timing later than the first timing and the reference data satisfies a first malfunction condition, a second determination unit for determining whether the acceleration included in the history information satisfies a second malfunction condition, and an output unit for outputting that the optical measuring device malfunctions when the first malfunction condition and the second malfunction condition are satisfied.
