かすことはできなかった。(Problems to be Solved by the Invention) However, since the radiation detector of the front surface detector housing portion 2 occupies a considerably large mounting space in the vertical direction of the central portion of the surface, the operation instruction display portion 7 detects the front surface detection. Since it cannot be installed at a position in the center of the surface of the container housing 2 which is easy for the person to be measured to see in the vertical direction, it avoids the mounting position of the radiation detector, and is usually moved to the left side toward that position, and on the mounting surface. It was attached flat. Therefore, it is natural that the operation instruction display unit 7 is generally difficult to see, but if the height of the person to be measured is different, the angle at which the operation instruction display unit 7 is viewed is different. Therefore, depending on the person to be measured, there is a problem in that it may be difficult to confirm the operation state because the instruction display may be clearly visible or may not be visible at all. Since the body cannot be moved during the measurement, the person to be measured could not move the body to a position where the instruction display was clearly visible.
