Patent ID: 7547140

Claim:
An electronic thermometer comprising: a temperature sensor which detects a temperature; a display portion which displays a measured temperature based on data detected by the temperature sensor; a buzzer which makes sound at least when the measurement is ended; and a control circuit including a circuit which controls the buzzer to make sound by determining a measurement end time and a circuit which processes data detected by the temperature sensor and displays the measurement temperature obtained by the processing on the display portion, wherein the buzzer comprises a vibration plate having opposite face sides, the vibration plate being fixed such that it is nipped from both face sides in the vicinity of the periphery of the vibration plate; a supporting portion which supports the vicinity of the periphery on one face of the vibration plate; and a pressing member having flexibility for pressing the vibration plate against the supporting portion by pressing the vicinity of the periphery of the other face of the vibration plate and further including a mechanism which presses the vicinity of the center of the pressing member on an opposite side to a side provided with the vibration plate so as to flex the pressing member, thereby pressing the vicinity of the periphery on the other face of the vibration plate due to a flexible reaction force of the pressing member.
