Patent ID: 8298484

Claim:
An analyzer for analyzing a sample, using an analysis piece provided with at least one reagent pad on a base material, the analyzer comprising: a placement part on which the analysis piece is placed; and a photometric measurer for photometric measurement of the analysis piece, the analysis piece being moved in a conveying direction from the placement part toward the photometric measurer, wherein the placement part is configured to hold the analysis piece in a first orientation in which a first end of the base material provided with said at least one reagent pad is oriented in a first direction perpendicular to the conveying direction with respect to a second end of the base material not provided with said at least one reagent pad, and a second orientation in which the first end is oriented in a second direction opposite to the first direction with respect to the second end, the second direction being perpendicular to the conveying direction and parallel to the first direction; and wherein the analyzer further comprises an orientation determiner for determining whether the analysis piece is in the first orientation or in the second orientation based on information from the photometric measurer.
