Abstract

PURPOSE:To maintain semipermanently an operation of thermometer without a battery, by using a solar battery and an overvoltage preventive diode for a powder source part. CONSTITUTION:In an electronic thermometer which is constituted of a temperature measuring part, a display part, a power source circuit part, and a temperature converting circuit, the power source circuit part is constituted of a solar battery 1. In such a state, when the solar battery 1 receives a light beam and generates electric power, it is supplied to an electronic thermometer circuit 3 and a thermometer is operated. Also, when an overvoltage is applied, an overvoltage preventive diode 2 consumes this power. In such a way, by using no alkali manganese battery nor silver oxide battery for the power source, there is no anxiety for a battery replacement caused by a battery leakage liquid or a circuit damage, etc. caused by the leakage liquid, and a a battery drinking accident of an infant, etc., which is safe and sanitary. Also, due to a fact that there is no necessity of a battery replacement, a complete liquid tight structure can be formed, and also since the solar battery is used for the power source, it can be used semipermanently if only there is a light beam.
