ABSTRACT:
Apparatus for reading an identification code from a blood sample container includes an elastic member (42) which engages the upper side (34) of the sample container. A rotary device rotates the elastic member bidirectionally. An up-and-down moving device moves the elastic member up and down. A rotating/up-and-down moving control device (56) controls the movement of the container. An identification code reader (19) reads the sample code from the container, and a reading controller (57) permits the identification code reader to read from the container as it rotates in either forward or reverse direction. The elastic member abuts the upper part of the sample container and rotates it. If the identification code reader cannot read the identification code when the container rotates in the forward direction, the elastic member rotates the sample container in the reverse direction for the identification code to be read again.
