Zusammenfassung:	PROBLEM TO BE SOLVED: To provide detailed soil property information on a boring core necessary for preparing a column diagram. SOLUTION: Light is applied to the boring core housed in a core housing box by using light sources different in wavelength characteristics, such as a visible near-infrared light source 34, a short-wavelength infrared light source 32, and an ultraviolet light source 36. Reflected light is received by using a visible near-infrared sensor 24, a short-wavelength infrared sensor 22, and an ultraviolet sensor 26. Further, emitted thermal infrared light is detected by a thermal infrared sensor 27 to obtain image data. These light sources and sensors are moved to scan the boring core by a moving mechanism 40, detailed image data on the entire boring core are recorded on a data recording part 60.
