Abstract
Abstract A sample-transporting path (11) is provided which includes holders (14a-14o) for holding containers (12a-12o), either empty or filled with liquid samples, a conveyor (11) for conveying the holders, and guide plates. The guide plates guide the holders holding filled containers to a first position where liquid samples will be sucked from some of the filled containers. Each of the holders (14a-14e) has first and second annular grooves (52a, 52b) cut in the outer periphery. The guide plates are guide edges horizontally protruding from two parallel walls forming the path (11). These guide edges are inserted in the first annular groove of the holder. A stopper is provided at the first position. The stopper has a stopper pin (50a) which thrusts into the gap between the second annular grooves (52b) of any two adjacent holders, thereby stopping the holders (14a-14e) located downstream of the path (11) with respect to the stopper pin (50a).

Claim 1
Independent Claim
228 words
A liquid-distributing apparatus characterized by comprising: a sample-transporting means (11) including holders (14a-14o) for holding containers (12a-12o), a conveyor (58) for conveying the holders, and guide means (54a, 55a) for guiding the holders to a first position where liquid samples will be sucked from some of the containers held by some of the holders, each holder being a hollow cylinder having at least two annular grooves (52a, 52b) cut in its outer periphery, said guide means having guide edges (54a, 55a) insertable in the first annular groove (52a) of the holder; data-reading means (18) for reading, from each of the containers containing a liquid sample, data showing items for which the sample will be analyzed and data showing the identity of the sample; means (31) for transporting the holders (33a-33j) holding empty containers in the same number as the items of analysis to a second position where each liquid sample will be distributed among the empty containers; means (39, 40) for distributing the liquid sample in small quantities from each of the containers (12a-12e) located in said first position, among the containers (32a-32e) located in said second position, in accordance with the data read by the data-reading means (18); and means (26, 74a-74f) for dividing the containers containing the small quantities of the liquid samples into groups in accordance with the data read by the data-reading means (18).
Claim 2
Dependent Claim
