BIOCHEMICAL MEASURING INSTRUMENT

摘要

PURPOSE:To simplify a measuring operation by providing a moving mechanism to a test piece insertion part so that a standard test piece or test piece in an unreaction state contained in a measuring instrument can be positioned to the test piece insertion part by such moving mechanism. CONSTITUTION:The moving mechanism 4 consists of a slender plate-shaped member 41 and a test piece holding part 42 is formed on the side of the member 41 facing an instrument body 1. The holding part 42 is so constructed that the standard test piece or the unreacted test piece 5 can be freely attachably and detachably mounted therein. Retaining pieces 42, 43 are projected and formed from both sides to prevent the dislodgment of the test piece 5. The exchange of the test piece 5 is easily executed by sliding the member 41 so as to project into the test piece insertion part 21 while a cover 3 is held open and exchanging the test piece by using a pincette or the like from above. The measuring operation is thus simplified.
