Abstract:
1. A blood cell counter comprising: a agitation device that mixes a whole blood sample in a sample container by moving the sample container; an aspirator that aspirates the whole blood sample by penetrating a lid of the sample container with an aspiration tube after mixing the whole blood sample; a detector that counts the blood cells in the whole blood sample aspirated by the aspirator; and a force applying member that applies a force to the sample container in an upright state after mixing so as to remove the whole blood sample from the lid of the sample container, wherein the force applying member comprises a roller that contacts an outer surface of the sample container and rotates the sample container around an axis parallel to the longitudinal direction of the sample container, and a force applicator that pushes the sample container to the roller while the sample container is rotated, and wherein a distance from an outer circumferential edge of the roller to a rotational center of the roller varies.
