A device for separating a reagent from a reactor includes a collecting means, provided with a liquid receiving port and a solid receiving port, a holding component disposed above the collecting means and used for placing the reactor, and a rotating mechanism for driving the holding component to rotate. The liquid receiving port and the solid receiving port are arranged at different positions in the circumferential direction of rotation of the holding component, when the holding component passes over the liquid receiving port, reagent in the reactor falls into the liquid receiving port, when the rotating mechanism continues rotating in the original direction until the holding component passes over the solid receiving port, the reactor falls into the solid receiving port from the holding component.

The present invention provides an automatic analysis device and an automatic specimen processing system having a component-rack supply mechanism that, in a state where a plurality of component racks each having a disposable component mounted thereon are stacked, separates only a component rack at the leading stage of the stack from the other component racks, and supplies the separated component rack to the automatic analysis device or the automatic specimen processing system. Specifically, the automatic analysis device and the automatic specimen processing system have a supply mechanism including a separation mechanism that, in a state where a plurality of component racks are stacked, separates only a component rack at the leading stage of the stack from the other component racks, where the separation mechanism includes a movable mechanism having a pair of downward-movement prevention members that can separate the leading stage from the second stage of the stacked component racks; and a correction mechanism having a pair of correction members that correct a positional deviation of the component racks in order to avoid an influence of the positional deviation of the stacked component racks.
