DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aggregating pattern determining plate transfer device, and more particularly to an aggregating pattern determining plate transferring device provided with an aggregating pattern determining portion at a predetermined position on a plate transport path.

2. Description of the Related Art In the medical field, as a method for detecting and analyzing various components, viruses, and the like in blood, a relatively large number of determination methods based on the aggregation pattern of blood have been conventionally performed. Standards are set. This determination of the presence or absence of aggregation is often made by visual determination with the naked eye. Specifically, the presence or absence of aggregation is determined as the area of a portion equal to or less than the reference luminance based on the predetermined luminance based on the distribution of particles in the reaction vessel (well).
In addition, it often depends on comprehensive judgment by human eyes, for example, by comparing with a standard aggregation pattern or a standard non-aggregation pattern, or by creating a continuous serial dilution series of a specimen sample.

[0003] On the other hand, this visual judgment involves inconveniences such as the necessity of a high level of skill and the judgment of individual differences. For this reason, recently, automation of determination using a one-dimensional light receiving element (one-dimensional CCD sensor) has been promoted.

[0004]

However, the automation in the above-mentioned conventional example is of a type in which the plate on which the sample for agglutination pattern determination is attached is manually placed on the agglutination pattern determination location. Many. For this reason, not only does it take a lot of time and effort to carry out the work of placing and carrying the plate, but also there is an inconvenience that the cohesion pattern on the plate is partially damaged by the vibration generated during the work of placing the plate. In order to eliminate the problem, the work must be performed carefully, which causes a disadvantage that the work efficiency is poor even if the automation of the determination is achieved.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to improve the disadvantages of the prior art, and in particular, when transferring a plate to a location where a flocculation pattern is determined, the plate is automatically and sequentially transported at a constant speed, whereby the aggregation pattern is reduced. An object of the present invention is to provide a plate transfer device for aggregating pattern determination, which enables continuous processing of a large number of attached plates in a short time.

At the same time, one of the belt conveyor mechanisms 11 starts running the belt conveyor section 11A and starts the ascent operation. Then, while lifting the lower plate 1 in the plate stocker 6, the belt conveyor unit 1 is lifted.
1A, and then transferred onto the guide means 2.

In this case, the plate 1 is placed on the guide means 2 relatively slowly while maintaining its horizontal state. When the plate 1 is placed on the guide means 2, the first transfer mechanism 33 constituting a part of the transfer force urging means 3 urges the first transfer force transmission mechanism 35 subsequently. Once moved on the plate 1 from the right to the left in FIG.
Stopped upstream of plate 1. Subsequently, the first transfer force transmission mechanism 35 operates to feed the plate 1 to the right direction in FIG.

At the aggregation pattern determination section 4, a plurality of aggregation patterns on the plate 1 are read by the aggregation pattern determination means 10 and the quality is determined according to a predetermined reference pattern. When the reading operation of the aggregation pattern is completed, the second transfer mechanism 34 constituting a part of the transfer force urging means 3 is urged by the first transfer force transmission mechanism 36 so that the plate 1 is once viewed on the plate 1. 1 moves from the right to the left, and stops at the upstream side of the plate 1.

Subsequently, the second transfer force transmitting mechanism 36 operates to transfer the plate 1 through the second transfer mechanism 34 to the right direction in FIG. As soon as the plate 1 is transported to the right end on the guide means 2, the other belt conveyor mechanism 12 immediately starts running the belt conveyor section 12A and starts a lifting operation. Then, the plate 1 on the guide means 2 is placed on the belt conveyor section 12A while being lifted, then transferred to the plate stocker 7, and lowered again to store the plate 1 at the lowest position in the plate stocker 7.

In the process of storing the plate 1 in the plate stocker 7, the other plates 1 in the plate stocker 7 are temporarily moved slightly upward by the stocker lift mechanism 9. Then, as soon as the plate 1 sent by the other belt conveyor mechanism 12 is stored at the lowest position in the plate stocker 7, the other plate 1 is lowered onto the lowest plate 1, whereby one plate 1 is completed. Hereinafter, the transfer and determination steps of the second and third plates 1 are repeatedly performed according to this.

[0047]

Since the present invention is constructed and functions as described above, according to the present invention, the plate conveyed along the guide means can be stopped with high accuracy at the aggregation pattern judging position by the action of the plate stopping mechanism. Therefore, the carrying-in time during measurement can be reduced, and thus a large number of plates can be determined in a relatively short time. As described above, the first and second transfer force urging means can be used. The first transfer force urging means sends the plate before the determination to the aggregation pattern determination location, and the second transfer force urging means applies the plate determined by the second transfer force urging means to the aggregation pattern. The first and second transfer force urging means can be operated simultaneously since the method of transferring the sheet from the determination point to the outside is employed. Ri can provide excellent agglutination pattern determination plate transfer device unprecedented that it is possible to further accelerate.
