Abstract

PURPOSE:To reduce the titled thermometer in size by switching a circuit part for detecting and measuring radiation energy from a body to be measured and a collimating light source by a changeover switch to supply electric power to them. CONSTITUTION:The changeover switch 9 for switching the circuit part 6 or the collimating light source 7 to supply electric power from a power supply part 8 to the circuit part 6 or the light source 7 is formed on a measuring part 3. When the switch 9 is turned to the light source 7 and the light source 7 is lighted up before the start of measurement, light radiated from the light source 7 is reflected by a dividing mirror 4, passed through an optical fiber 2 and projected upon the body 0 to be measured by a condensing part 1 and the position of the body 0 or the condensing part 1 is adjusted to determine the measuring position. When the switch 9 is turned to the circuit part 6 side and electric power is supplied from the power supply part 8 to the circuit part 6, radiation energy from the object 9 is passed through the optical fiber 2 and mirror 2 and made incident upon a detector 5 and the electric signal is converted into a signal corresponding to the temperature by the circuit part 6 to measure the temperature.
