  • Publication number: 20240068884
    Abstract: A thermosensitive part sensing temperature; a temperature sensor for measurement provided in the unit and measuring temperature by contacting the unit with a body to be measured; a temperature detecting part detecting, from when the unit contacts the body, the time when the sensor senses a difference from an initial temperature of the sensor, and a measured temperature of the sensor at that time, and detecting, from when the difference is sensed, a time after a certain length of time and a measured temperature of the sensor at that time; an estimating part estimating, from the time when the difference is sensed and a time after a certain length of time, the time when the thermosensitive part contacts the body, and the measured temperature at that time; and a heat conduction analyzing part estimating the measured temperature based on output information from the temperature detecting part and the estimating part.
