Abstract:
1. An ear thermometer comprising: a body temperature measuring part to sense infrared rays radiated from an ear hole depth and thereby measure a body temperature; a liquid crystal display part to display the body temperature measured by the body temperature measuring part; a backlight emitting part to irradiate the liquid crystal display part with backlight; a driving-controlling part to display the body temperature measured by the body temperature measuring part on the liquid crystal display part and drive the backlight emitting part so that the quantity of the backlight that irradiates the liquid crystal display part from the backlight emitting part may gradually change from a maximum level to an off level; and a power supply control part that intermittently carries out power supply to the body temperature measuring part for a predetermined time from the start of power supply to the body temperature measuring part by gradually increasing a predetermined small ON/OFF ratio to a predetermined large ON/OFF ratio, and after the predetermined time elapses, continuously carries out power supply to the body temperature measuring part.
