In general, the thermometer, which is one of the conventional digital sensing devices, can measure body temperature only by turning on the power by operating the power switch button to turn on the screen or display the operation, and after use, operate the power switch button Turn off the power.

Step2) Press the "ON" button to start the measurement. Step3) Remove the instrument after the measurement is completed. Step4) Press the "OFF" button to start the measurement. Button is pressed to operate as a process of measuring operation stop.

A conventional digital thermometer which operates in this manner will be described in detail with reference to FIGS. 1A to 1C. As shown in FIGS. 1A and 1B, a digital thermometer product in which one switch button is used and two digital thermometers are used have.

1A, when one switch button PB1 is used in the clinical thermometer, when the user turns on the power by the operation of the one switch button PB1, the screen display unit 40 is activated and a circuit activation state And after the use is completed, the power is turned off by the operation of the switch button PB1. Some thermometers have a timer-off function that automatically turns off after a certain period of time has elapsed since the pushing operation of the switch button PB1.

When the two switch buttons PB1 and PB2 of the clinical thermometer are provided as shown in FIG. 1B, one of them is the power switch button PB1 and the other is the temperature measurement operation switch button PB2. 1C. ≪ / RTI >
