Abstract
A small object identifying device and its identifying method according to which a large number of small objects can be identified. In one embodiment, the device includes a dispersion region section which disperses a large quantity of several kinds of small objects which are labeled by a combination of the presence/absence or measure of label elements of several kinds. A measuring device distributes and associates kinds of said label elements to two or more measurement points and measures the presence/absence or the measure of said label elements of the kinds which have been associated with respective measurement points. An identifying section associates the measurement results measured at each measurement point to thereby identify said small objects.
