Abstract: A microarraying head 51 has a base portion 57 and a plurality of needles 53. The needles 53 are arranged in parallel with one another on the base portion 57. The needles 53 place a solution on substrates 3 with the top ends of the needles 53 touching substrates 3. Then, the needles 53 retain the solution including biological samples and form spots of the solution on the substrates 3. A space 58 for supplying cleansing fluid or the like is provided in the base portion 57 so as to extend all over the plurality of needles 53. Since the plurality of needles 53 can be all cleansed with substantially uniform pressure applied thereto, all the plurality of needles 53 can cleansed surely in a short time.

Abstract: There is provided a method of correcting position and attitude of an object to be held capable of reducing the number of image processing steps and simplifying the method of correcting shifts in the position and attitude of the object with respect to a holding member. The object to be held is detachably held to the holding member and a fiducial mark 1 and a fiducial mark 2 are applied to the object. First, the fiducial mark 1 is subjected to an image processing so as to obtain position data of the fiducial mark 1 (S2). Next, the holding member holding the object to be held is rotated substantially by 180 degrees in a horizontal plane (S3). Then, the fiducial mark 2 rotated by 180 degrees is subjected to an image processing so as to obtain position data of the fiducial mark 2 (S4).

Abstract: A present micro array manufacturing apparatus includes a substrate placement portion 11 on which a plurality of substrates can be arranged, a tighter plate 12 for storing a solution including a living body sample, a solution storing member 52 for taking in the solution from the tighter plate 12 and storing the solution therein, and a needle 51 which can be inserted into the solution storing member 52 to allow the solution stored in the solution storing member 52 to adhere onto each of the substrates by a given quantity, wherein the solution storing member 52 and needle 51 are moved in directions where they approach and part away from the substrates to thereby form spots on the substrates. And, the individual operations of the solution storing member 52 and needle 51 are carried out by single drive means 32.
