Abstract: The purpose of the present invention is to provide a highly reliable specimen carrier device with which it is possible to position a specimen holder in a specific place with high accuracy, thereby enabling the stable performance of a treatment. In order to achieve this purpose, the present invention provides a specimen carrier device that is equipped with: a specimen holder which retains a specimen container and which is equipped with a magnetic body; and a first positioning means which is disposed beneath a carrier surface and which conveys and stops the specimen holder by attracting and repelling the magnetic body, wherein a second positioning means for pressing the specimen holder or the specimen container is provided on the carrier surface.

Abstract: Provided is an automatic analysis device in which even an operator can easily identify the type of processing and the type of individual and erroneous setting hardly occurs.
A vessel holder for holding a sample vessel, a reading unit for reading an identification area formed in the vessel holder, and a control unit for performing processing based on information read by the reading unit are included, in which the control unit identifies the type of processing based on the type of color applied to the identification area, and identifies the type of individual in the sample

Abstract: Provided is a preprocessing device that carries out a dispensing process for aspirating a liquid sample accommodated in a sample container, and subsequently discharging and dispensing the sample into another sample container, the preprocessing device comprising: a dispensing nozzle; a dispensing nozzle tip detachably provided to the distal end of the dispensing nozzle; a disposal box in which the dispensing nozzle tip is disposed of after having been removed from the dispensing nozzle; and a cutting mechanism for cutting a dispensing nozzle tip inserted into a removal part, which removes the dispensing nozzle tip from the dispensing nozzle, from the longitudinal-direction side. This makes it possible to improve accommodation efficiency while suppressing accumulation of disposed-of dispensing nozzle tips.

Abstract: The present invention makes a directional control means for a specimen carrier unnecessary, reduces costs, and saves time. A high friction member 102 is provided on the bottom surface of a specimen carrier 100, thereby offsetting the center 14 of the frictional force 11 between the bottom surface and a conveyance surface, at a position separate from the rotational center of the bottom part of the specimen carrier 100. As a result, the friction between the conveyance surface and the bottom surface during conveyance of the specimen carrier 100 aligns the orientation of the specimen carrier 100 with respect to a conveyance direction 10, and makes it possible to make a carrier ID 101 and a specimen ID label 151 face towards a barcode reader.
