Sample arraying/assembling device, its method, and apparatus using sample assembly

A sample arraying/assembling device comprising:

• a distributing section which is capable of holding respective solutions containing samples to be distributed, and which has a plurality of holding ends arranged in a predetermined matrix, the predetermined matrix comprising a first plurality of columns or lines spaced in a parallel relation at predetermined first spacing intervals in a first direction, and a second plurality of columns or lines spaced in a parallel relation at predetermined second spacing intervals in a second direction, the first and second directions being coplanar and mutually different, each of the columns or lines in the second plurality of columns or lines having a first length equal to at least the sum of the predetermined first spacing intervals;
• a wound body which has a plane surface wound with a string-like or thread-like slender foundation member formed from a flexible material on which samples are to be distributed in the predetermined matrix, wherein the foundation member is wound on the plane surface at winding intervals equaling the predetermined second spacing intervals, respectively, so that the respective holding ends can come into contact with the foundation member and the samples can be distributed on said foundation member in the predetermined matrix;
• a core joined to said wound body by said foundation member, the core having an axis of rotation and a peripheral curved face or two side faces or more either on which said samples are distributed in predetermined positions with intervals, or being wound or coated with said foundation member on which said samples are distributed at predetermined positions with intervals around said axis of rotation;
• a translucent or semitranslucent pipette tip capable of storing said core and having an axis and a fluid drawing and discharging opening;
• a rotating section which intermittently rotates said pipette tip and said core stored in said pipette tip, around the axis of said pipette tip or the core for each predetermined angle;
• and
• an optical information acquisition section which receives light from said core based on the intermittent rotation of said rotating section and obtains optical information.
