動作せずトラブルの原因となるという問題があった。When processing a sample stored in a rack (aspiration, addition of a reagent, stirring, dispensing, etc.),
There is often a difference in processing time depending on the inspection item. Therefore, when transporting the sample-containing rack by the transport belt, the transport speed of each transport belt is often different, so that the distance and the interval between the rack and the next rack must be transported while extending or contracting. As a general means for separating the continuous racks, as shown in FIG. 4, if the speeds of two conveyor belts, for example, the two conveyor belts 6c and 6d in FIG. 3, are respectively v 1 and v 2 , v 1 > v 2
Alternatively, v 1 <v 2 was often set. However, when the distance between the racks is determined based on the speed difference as described above, there is a problem that the rack does not operate smoothly when moving on to the next conveyor belt, which causes a trouble.

す必要があるかによって決める。The operation of the automatic sample transporting apparatus as described above will be described below with reference to FIGS. 1 and 2 in which a certain transport belt is 6d, and a transport belt before the certain transport belt 6d is 6c. When the rack 5 transferred from the conveyor belt 6c is transferred to the conveyor belt 6d and the tip (surface) touches the sensor 7, both the conveyor belt 6c and the conveyor belt 6d temporarily stop. Next, after a predetermined time (for example, 1 or 2 seconds), the driving motor or the driving mechanism 9 of the transport belt 6c reverses the transport belt 6c (FIG. 2). When the distance between the rack 5 of the conveyor belt 6d and the rack 5 on the previous conveyor belt 6c reaches the intended predetermined distance (L), the conveyor belt 6c is temporarily stopped. During this time, the rack 5 on the conveyor belt 6d is moved in another direction for processing. Then, these two conveyor belts 6c and 6d are driven again as before. When the rack 5 of the conveyor belt 6c is transferred onto the conveyor belt 6d again, and the tip (surface) of the rack 5 touches the sensor 7, the above operations are repeated. The time between the stop of the conveyor belts 6c and 6d and the start of the reverse rotation of the conveyor belt 6c is determined by the distance between the rack 5 and the rack 5 before it.

よって決めればよい。When the leading end (surface) of the rack 5 transferred to the conveyor belt 6d touches the sensor 7, the conveyor belts 6c and 6d temporarily stop and a motor or a driving mechanism for driving the previous conveyor belt 6c. 9 reverses the conveyor belt 6c. That is, in FIG. 1, the rack 5 is moving on the transport belt 6d, and another rack 5, 5, etc. is moving on the transport belt. Then, it is assumed that the distance between the rack 5 and the previous rack 5 needs to be increased. The sensor 7 is connected to a motor for driving the conveyor belts 6c and 6d or a CPU 8 for controlling the driving mechanisms 9 and 10. In this case, the sensor 7 is operated as follows. (1) When the rack 5 transferred from the transport belt 6c is transferred to the transport belt 6d and the tip (surface) touches the sensor 7, both the transport belt 6c and the transport belt 6d temporarily stop. (2) Next, after a predetermined time (for example, 1 or 2 seconds), the driving motor or the driving mechanism 9 of the transport belt 6c reverses the transport belt 6c (FIG. 2). (3) Rack 5 of transport belt 6d and previous transport belt 6c
When the distance from the upper rack 5 reaches the intended predetermined distance (L), the transport belt 6c is temporarily stopped. During this time, the rack 5 on the transport belt 6d is moved or processed in another direction. Then, these two conveyor belts 6c and 6d are driven again as before. (4) The rack 5 of the conveyor belt 6c is transferred onto the conveyor belt 6d again, and when the tip (surface) of the rack 5 touches the sensor 7, the above operations (1) to (3) are repeated. In the above operation, the time between the stop of the conveyor belts 6c and 6d and the start of the reverse rotation of the conveyor belt 6c is determined by the rack 5
The distance may be determined depending on how much distance it is necessary to separate the rack 5 from the rack 5.
