Classification: CPC G  B | IPC B  G

Claim 5:
6. An automated analyzing device, comprising:
a reagent vessel container that is capable of holding a plurality of reagent vessels;
a detector that performs a predetermined analysis of a sample in a reaction solution including a reagent; and
a tip rack loading apparatus that supplies an expendable used for analysis of the sample,
wherein the tip rack loading apparatus includes:
a drawer that is supported so as to be horizontally movable in a front-rear direction between an open position and a closed position, wherein a position of the drawer in the closed position is variable,
a front-face opening through which the drawer is movable between the open position and the closed position,
a table that allows an expendable used for analysis to be mounted in the drawer,
a guide rail structure that, while the drawer is moved toward a rear side from the open position to the closed position, moves horizontally until the expendable mounted on the table passes through the front-face opening from a front side to the rear side and moves the table toward an upper side of the front-face opening in synchronization with horizontal movement of the drawer toward the rear side after the expendable mounted on the table passes through the front-face opening, and
a positioning structure, including a first guide roller positioned in the guide rail;
wherein the guide rail structure includes a first guide groove that includes a vertical groove portion at an innermost end of the first guide groove corresponding to the closed position, and the positioning structure is arranged to support the table via interaction with the first guide groove;
wherein a greater curvature portion of the first guide groove with a greater curvature than the vertical groove portion is provided adjacent to the vertical groove portion;
wherein the position of the table is constrained by fitting the positioning structure in the vertical groove portion on a closed position side of the greater curvature portion; and
wherein, based on a configuration of the vertical groove portion, the table stops in the front-rear direction even when the drawer is displaced in the front-rear direction.
