Classification: CPC G  A | IPC G

Claim 0:
1. An ear thermometer, comprising:
a probe attached to an ear hole of a temperature measurement target person and comprising:
an infrared sensor unit measuring a temperature of an eardrum of an ear of the temperature measurement target person in a non-contact manner, the probe
a probe body inserted into the ear hole of the temperature measurement target person;
a housing for supporting the probe body; and
an in-ear type earpiece attached to the probe body and abutted on an inside of the ear hole of the temperature measurement target person,

the infrared sensor unit comprising a first sensor and a second sensor arranged in the probe body and spaced apart by a predetermined distance along a direction substantially orthogonal to the eardrum when the probe body is inserted into the ear hole of the temperature measurement target person;
a first linearizer for linearizing first temperature data acquired by the first sensor;
a second linearizer for linearizing the second temperature data acquired by the second sensor;
a radiation temperature convertor for calculating a radiation temperature by inputting a value obtained by the first linearizer into a predetermined conversion formula; and
a body temperature convertor for calculating the body temperature by adding the radiation temperature to the value obtained by the second linearizer.
