Patent ID: 7988353

Claim:
An electronic thermometer comprising: a temperature sensing means for sensing a temperature of a part to be measured, a maximum temperature value storing means for storing a maximum temperature value of the temperature being sensed, a prediction means for predicting an equilibrium temperature by using the temperature being sensed, and a temperature display means having a temperature display unit, wherein the temperature display means switches a display of the temperature display unit from the display of the equilibrium temperature being predicted by the prediction means to the display of the maximum temperature value, based on a determination of whether there is a change for a predetermined period of time in the maximum temperature value stored in the maximum temperature value storing means, when there is no change for a predetermined period of time in the maximum temperature value stored in the maximum temperature value storing means, and when a new maximum temperature value stored in the maximum temperature value storing means falls within a range between an old maximum temperature value a predetermined period of time before and a temperature value obtained by adding a predetermined temperature to the old maximum temperature value.
