本発明は、赤外線センサを用いて、たとえば人体等の温
度を測定する放射温度計に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radiation thermometer that measures the temperature of, for example, a human body using an infrared sensor.
赤外線センサを用いた放射温度計は、測温時間が短く、
また被測定物に非接触で、その温度を測定することがで
きるので、広く各種の温度測定に用いられている。Radiation thermometers using infrared sensors have a short temperature measurement time.
Furthermore, since the temperature of the object to be measured can be measured without contacting it, it is widely used for various temperature measurements.

（ＬＣＤ）５５が設けられている。FIG. 5 is an outline drawing of a conventional radiation thermometer. A probe 52 to be inserted into an object to be measured, such as a human ear, is provided at the left end of a case 51 of the radiation thermometer. Inside the case 51, there are provided a concave surface [53 that collects infrared rays emitted from the ear of a human body, which is an object to be measured, a thermomobile 54 that converts the collected infrared rays into electromotive force, and the like. A liquid crystal display (LCD) 55 is provided in the center of the case 51 to display temperature measurement results.

。The person taking the measurement grasps the center of the case 51 and turns on the power switch 56.
is turned ON, and the probe 52 is inserted into the human ear that is the object to be measured. Infrared rays emitted from the ear enter the concave mirror 53 via the probe 52, are reflected and focused by the concave mirror 53, and enter the thermopile 54.Next, when the hold switch 57 is pressed, the electromotive force and side temperature of the thermopile 54 are reduced. Since the temperature of the object to be measured obtained by processing the signal from the element 58 is held on the liquid crystal display 55, the temperature of the object to be measured can be read even if the probe 52 is removed from the object.

の測温素子５８によって測定し、この測定結果に基づい
て、サーモパイル５４の出力値を補正している。By the way, in thermopiles and the like used as infrared sensors, the temperature difference between the hot junction and the cold junction that occurs when infrared rays from the object to be measured enter the hot junction becomes a thermoelectromotive force, and the electromotive force corresponding to the temperature difference is generated. Output. The temperature of the object to be measured is measured based on this electromotive force. In order to obtain accurate output from such a thermopile 54, the temperature of the cold junction (room temperature) is measured by a temperature measuring element 58 such as a thermistor, diode, or transistor, and the output value of the thermopile 54 is corrected based on this measurement result. are doing.

め、測定結果に誤差が生ずるという欠点がある。However, the thermopile 54 is a very sensitive sensor, and when measuring temperature, there is a gap of about 1/1 between the hot junction and the cold junction.
A detectable output voltage appears even if there is a temperature gradient of 0,000"C.For this reason, with conventional radiation thermometers, there is no problem when the temperature measurement time is short, but it is difficult to measure the body temperature of a large number of people, for example. When the temperature measurement time is long, such as when measuring the temperature of each part continuously, the temperature of the case 51 of the radiation thermometer rises due to the temperature of the measurer's hand, and the temperature of the thermopile 54 increases. An unnecessary temperature gradient may occur between the contact and the cold junction, or the thermopile 54 may
Since there is a temperature difference between the cold junction and the side heating element, there is a drawback that errors occur in the measurement results.

。On the other hand, as in JP-A No. 61-117422, by keeping the thermopile 54, which is an infrared sensor, at a constant temperature during measurement, thermal disturbances caused by outside air and heat transfer from the hands of the person being measured are prevented, resulting in accurate measurements. Temperature measurement can be performed. However, although this method is technically excellent, it has the disadvantage that the temperature of the thermopile 54 must be kept constant, making the structure complicated and expensive.
