2. Description of the Related Art When collecting data using a radiation thermometer or the like, it is convenient to be able to record the date and time of measurement and the measurement location of a target (object to be measured). Conventionally, those parameters are added together with data. Further, in order to save the trouble, a so-called data logger having a recording device or a storage device built in or connected to a measuring instrument is used. In addition, when used for proof of work, or when the shape or structure of the measurement point is complicated, the measurement point and its surroundings are illustrated in detail, or a still camera or video camera is used to explain the situation in detail. And show it. In this case, the information of the measurement point is more specifically obtained and easy to understand, but since the information (photograph) of the measurement point and the measurement data come out separately, there is a drawback that they must always be edited. .

[0003] From such a viewpoint, it is desired to more easily record and display measurement data (temperature measurement value) and supplementary information such as a measurement location and a measurement date and time.

It is configured so as not to overlap with light as much as possible.

Therefore, in the finder, a still image can be obtained in the form of including the measurement data of the radiation thermometer if the imaging device is a still camera, while a moving image can be obtained in the case of a video camera. The data can be collected, organized, and evaluated smoothly.
