The present invention achieves an automatic analysis device which has a probe guard for which the range of motion for accessing a specimen container installation section is small and which can be moved without being removed from a specimen installation section. The directions of movement of a probe guard are the vertical direction of a specimen container erection mechanism and the horizontal direction within an upper region of the specimen container erection mechanism, and a specimen container can be accessed without the need to move the probe guard to outside the upper region of the specimen container erection mechanism. Accordingly, it is possible to achieve an automatic analysis device which has a probe guard for which the range of motion for accessing a specimen installation section is small and which can be moved without being removed from a specimen container erection mechanism.

Automatic analysis device

To provide an automated analyzer with a built-in, user-friendly printer that can avoid contamination of printed paper of the printer by having a housing front wallprovided in a recessed manner from a front endof a housing upper portion that has disposed thereon a sample disc, a reagent disc, a reaction disc, a sample dispensing mechanism, and a reagent dispensing mechanism, and by having a printerand a paper receptacledisposed on the housing front wall. The front end portion of the housing upper portion that projects beyond the housing front wall serves as eaves, thereby preventing a sample or a reagent that may be spilled on the housing upper portion from staining the printer or printing paper.

Automated analyzer

In an automatic analysis device, when an external force acts on a probe guardin a horizontal direction, the probe guardmoves in a direction escaping from the external force around a center portionof a test body container installing mechanism, and the probe guardis separated from a fixed position. An outer circumferential wallof the probe guardinvades a test body sampling mechanism track, and thus a risk that a sampling nozzleof a test body sampling mechanisminvades the test body container installing mechanismis avoided by the outer circumferential wall. When the probe guardis separated from the fixed position, this is detected, and thus the operation of the test body sampling mechanismand the test body container installing mechanismis stopped.

Biochemical analyzer

Cover of a biochemical analyzer

An automatic analyzer having a positioning member connected to a nozzle support jig used to install a rinse nozzle having a suction member. The positioning member is present at a lower position than that of the suction member, has a vertically movable construction, and during a downward movement of the rinse mechanism, is brought close to/inserted into the reaction cuvette earlier than the suction member. Thus, the positioning member adjusts an inserting position of the suction member appropriately if the stopping position of the reaction cuvette deviates.
