Abstract: A data converting method for reordered prints in which print data given in the terms of a length from the end of a film strip is converted into a data from the end of said film strip with reference to a notch. A length from the end of the film strip to a frame to be printed according to the reorder is measured on the basis of the print data, so that a notch formed at a portion other than that corresponding to said length is accepted as information of no print, whereas a notch formed at the corresponding portion is accepted as information of print. In case there is formed no notch at the portion corresponding to the frame to be printed, a notch is newly formed with reference to the frame of the corresponding portion and the newly formed notch is accepted as information of print.

Abstract: In a method of measuring erythrocyte sedimentation rate of the type wherein the upper level of a blood sample contained in a vertical test tube is detected by a photoelectric detection unit, the red blood corpuscles are caused to precipitate for a definite interval and the upper level of the precipitated red blood corpuscles is detected by descending the photoelectric detection unit along the test tube thereby detecting the rate of the sedimentation of red blood corpuscles, the photoelectric detection unit is stopped at a position a small distance corresponding to the air bubble or coagulated substance from the upper level. The photoelectric detection unit is descended after said definite interval for detecting the interface between the blood serum and the precipitated red blood corpuscles.
