Abstract

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.

First claim

The invention claimed is:

1. An automatic analysis device equipped with a consumable-item supply device to supply a consumable-item rack which has an upper side on which consumable items are held and has flanges provided in a lower place, comprising:
a platform that is capable of holding a plurality of the consumable-item racks in a state in which the consumable-item racks are stacked;
a driving unit that moves, in a vertical direction, the platform holding the consumable-item racks in a horizontal position;
a controller programmed to control operation of the driving unit; and
a pair of separation mechanisms that are placed to be spaced at a certain distance apart in a horizontal direction, the pair of separation mechanisms separating an uppermost consumable-item rack from the consumable-item racks which are stacked,
wherein each one of the pair of separation mechanisms has a support portion, including a plurality of support portion sections, that is movable and abuts on the underside of one of the flanges to support a consumable rack, and a correction portion, including a plurality of correction portion sections, that is stationary and abuts on a side face of the flange to correct a position of the consumable-item rack, wherein the support portion sections and the correction portion sections are alternately arranged along a longitudinal axis of each of the separation mechanisms.

2. The automatic analysis device according to claim 1 ,
wherein the controller moves the platform upward a first distance, and then moves the platform downward a second distance which is shorter than the first distance, such that the flanges of the uppermost consumable-item rack are positioned above the support portions and also the flanges of a consumable-item rack located directly below the uppermost consumable-item rack are positioned below the support portions.

3. The automatic analysis device according to claim 1 , wherein
the pair of separation mechanisms has elastic bodies urging the support portions toward the consumable-item rack.

4. The automatic analysis device according to claim 1 ,
wherein the support portion and the correction portion are placed to be adjacent to each other.

5. The automatic analysis device according to claim 1 ,
wherein each of the support portions is capable of moving between a first position in which the consumable-item rack is able to be supported, and a second position in which the consumable item is able to pass through between the support portions, and
when the support portions are in the first position, a distance (L) between leading ends of the flanges is longer than a distance (L 2 ) between the support portions and also is shorter than a distance (L 1 ) between the holding portions.

6. The automatic analysis device according to claim 1 ,
wherein each of the support portions is capable of moving between a first position in which the consumable-item rack is able to be supported, and a second position in which the consumable item is able to pass through between the support portions, and
when the support portions are in the second position, a distance (L) between leading ends of the flanges is approximately equal to a distance (L 2 ) between the support portions.

7. The automatic analysis device according to claim 1 ,
wherein the consumable items are tips, containers or both.
