A part of a human body is caused to contact the surface layer of a recording medium over which a plurality of metallic grains with an outside size of 200 nm or less are distributed. Then, secretions from the skin surface of the body part are caused to adhere to the surface layer of the recording medium to take the print of the body part. If light is irradiated to the recording medium, specific optical characteristics resulting from the surface structure of the recording medium are obtained, and therefore the color of the recording medium varies between a region having secretions and a region having no secretions. This renders it possible to record a visible print on the recording medium.

Each of samples is supported by one of the sensor sections. A scanning mirror scans the sensor sections of the multi-channel sensor with measuring light. A scanning controller controls the scanning mirror and stores information, which represents scanning positions of the measuring light with respect to the multi-channel sensor. A detector receives reflected light or transmitted light, which is radiated out from each of the sensor sections when each of the sensor sections is scanned with the measuring light. The detector thus detects the physical characteristics of the reflected light or the transmitted light.
