Abstract

An electronic thermometer includes sensing member for sensing a temperature to be taken thereby, storage member for storing the sensed temperature from the sensing member, judging member for judging whether the change of the sensed temperature is a predetermined change, predicting member for predicting a steady temperature based on the sensed temperature when the judging member produces the judge of the predetermined change, and displaying member for displaying the sensed temperature or the steady temperature predicted by the predicting member.

Claims

1. An electronic thermometer, comprising:

sensing means for sensing a temperature to be taken by the thermometer;

storage means for storing said sensed temperature from said sensing means;

judging means for judging whether said sensed temperature is changing within a predetermined range of change;

predicting means for predicting a steady temperature based on said sensed temperature, wherein the operation of the predicting means is conditioned on said judging means judging that said sensed temperature is changing within the predetermined range of change; and

displaying means for displaying said sensed temperature or said steady temperature predicted by said predicting means.

2. An electronic thermometer according to claim 1, wherein said sensed temperature is displayed on said display means as long as said predicted steady temperature is not produced by said predicting means.

3. An electronic thermometer according to claim 1, wherein said predetermined change represents that said sensed temperature is obtained by taking a body temperature.

4. An electronic thermometer according to claim 1, wherein the judging means judges whether the change of said sensed temperature is outside said predetermined range of change.

5. An electronic thermometer according to claim 1, wherein the judging means judges whether the change of said sensed temperature is outside said predetermined range of change which indicates that the sensed temperature is obtained from other than body temperature.
