The present invention relates to a body temperature measuring device. The body temperature measuring device includes a battery unit which supplies power an input unit which generates and applies a button input signal a power on/off unit which turns on or off the power supply from the battery unit according to the button input signal applied from the input unit a converter unit which includes a step-up converter and converts the power supplied from the power on/off unit to a proper voltage a temperature sensor unit which is operated by the power converted into the proper voltage by the converter unit and provides a measured body temperature converted into a voltage a controller unit which is operated by the power converted into the proper voltage by the converter unit, provides a power maintaining signal to the power on/off unit, converts the analog voltage value provided by the temperature sensor unit into a digital voltage value, provides a temperature value corresponding to the voltage value, maintains a sleep state for a preset period of time, returns to a power-on state, repeats the sleep state and the power-on state for a preset number of times, and releases the power maintaining signal an LCD driver unit which provides the temperature value provided from the controller unit to display and a wireless communication unit which includes a Bluetooth module and sends the temperature value delivered from the controller unit to a paired smart device.COPYRIGHT KIPO 2014[Reference numerals] (110) Battery unit(120) Input unit(130) Power on/off unit(140) Converter unit(150) Temperature sensor unit(160) Controller unit(170) LCD driver unit(180) Display unit(190) Wireless communication unit본 발명은 체온 측정 장치에 관한 것으로, 전원을 공급하는 배터리부와, 버튼 입력 신호를 발생시켜 인가하는 입력부와, 입력부로부터 인가되는 상기 버튼 입력 신호에 따라 배터리부로부터의 전원 공급을 온/오프(on/off)시키는 전원 온/오프부와, 스텝업 컨버터(step-up converter)를 포함하여 전원 온/오프부로부터 공급되는 전원을 적정 전압으로 변환하는 컨버터부와, 컨버터부에서 적정전압으로 변환된 전원 공급에 따라 동작하며, 측정된 체온을 전압으로 변환하여 제공하는 온도 센서부와, 컨버터부에서 적정전압
