ABSTRACT:
A new mechanism for supplying in sequence unused regions of an analytical tape by predetermined length to an analytical section arranged in an apparatus for biochemical analysis of a liquid sample is disclosed. The mechanism comprises a driving means for moving the analytical tape to supply its unused regions to the analytical section; a means for detecting length of the unused regions of the tape supplied to the analytical section comprising a roller which is arranged in contact with a surface of the tape so that it rotates with movement of the tape for the supply of the unused regions to the analytical section and a means for detecting number or angle of the rotation of the roller, and a means for controlling operation of the driving means according to the detected number or angle of the rotation of the roller.
