る。Like the mercury thermometer, the above embodiment is an example in which the maximum temperature during body temperature measurement is displayed. Generally, a thermistor is used as the temperature sensor 1, and the temperature at the temperature measurement site is input to the electronic thermometer as a change in resistance value. The A/D conversion means 2 converts the body temperature signal (analog signal) from the temperature sensor 1 into a digital signal, and when a thermistor is used as the temperature sensor 1, the resistance value of the thermistor is converted into a direct current proportional to the resistance value. The signal is converted into a voltage, amplified, etc., and converted into a digital signal by the A/D conversion means 2. Alternatively, there is an A/D conversion means 2 in which an oscillation circuit is constructed using a thermistor as one element for determining the oscillation frequency, and the oscillation output is counted. The body temperature data digitized by the A/D conversion means 2 is input into the comparison means 3 and the maximum temperature storage means 4. The maximum temperature storage means 4 stores the maximum temperature detected after the measurement start switch 6 is turned on, but when the measurement start switch 6 is turned on, the body temperature data from the A/D conversion means 2 (temperature sensor 1 The current temperature detected by the device is stored unconditionally. Further, the maximum temperature data stored in the maximum temperature storage means 4 is inputted to the comparison means 3 and the display control means 6. The comparison means 3 compares the body temperature data from the A/D conversion means 2 and the maximum temperature data from the maximum temperature storage means 4, and when the body temperature data is high, the body temperature data from the A/D conversion means 2 is stored in the maximum temperature storage means 4. Outputs data storage command.

検出された最高温度を表示する。Upon receiving the storage command from the comparison means 3, the maximum temperature storage means 4 updates its memory with the body temperature data from the A/D conversion means 2 as the maximum temperature data. The display means 7 is generally a liquid crystal or an LED and a fluorescent display tube, and the display control means 6 displays the maximum temperature data of the maximum temperature storage means 4 on the display means 7.
It converts the signal into a drive signal suitable for the display and controls the display means. With the above configuration, the display means 7 displays the maximum temperature detected from the start of measurement, similar to a mercury thermometer.

題で測定をやシ直すことが多い。Temperature measurement using a mercury thermometer is similar, but during temperature measurement, the temperature detection part with a temperature sensor is hidden from view and is attached to the temperature measurement site, so even if the temperature detection part moves away from the temperature measurement site, it will not be noticed and the measurement will be carried out. The results may differ greatly from the actual body temperature. Especially when an adult takes the temperature of an infant, the above-mentioned problem often causes the measurement to be postponed.
