For example, the transmitted light D transmitted through the mandarin orange A while avoiding the vine portion or the core portion. Is detected by the transmitted light detecting device 22, so that accurate detection information can be obtained. In addition, the rotation speed of the rotation imparting belt 3a is set to an arbitrary speed (for example, high speed, depending on the size of the fruit or vegetable A).
The speed may be variable (medium speed or low speed), low speed rotation may be performed in a direction opposite to the transport direction, or rotation may be temporarily stopped.

As shown in FIG. 2, the above-described sugar acidity measuring device 4 is provided with a light source 20 composed of, for example, a halogen lamp, an ultraviolet lamp or the like, on the upper circumference of the mandarin orange A mounted between the supporting rollers 13.
