PURPOSE: To control the flow of a fluid flexibly by switching a peristalsis pump motor in stepping successively. CONSTITUTION: A peristalsis pump 12 that is driven by a peristalsis pump motor can generated the flow of a reagent to a measuring device 54 within a conduit and the measuring device 54 responds to the reaction between the reagent and a sample. Further, to introduce a predetermined capacity of sample liquid into the flow of the reagent, a sample introducing device is arranged in front of the measuring device of the conduit with a certain distance. Then, the peristalsis pump motor is formed by a motor 16 that is switched successively, thus forming a device so that a certain discharge is given with time. |
