摘要： PROBLEM TO BE SOLVED: To simplify the control over rack-transfer without control over rack- transfer by a central control by repeatedly transmitting drop-in information while transferring racks. SOLUTION: A specimen processing system is formed of a rack introducing part 1 to transfer racks, transferring lines 2, 3, 4, and 5, a rack housing part 6, specimen processing units 100, 200, 300, and 400 for processing specimens, etc. By this, each transferring line is controlled only by the conditions of an adjacent transferring line and a specimen processing unit, and the information on the dropping-in of racks necessary for control is obtained from an adjacent transferring line and a specimen processing unit. Therefore, it is possible to perform decentralized control and to prevent the concentration of load as in centralized control. In addition, as the transferring lines independently control transfer on the basis of the drop-in information, it is possible to adapt to the increase and reduction of the number of lines and specimen processing units without changing software or hardware.

摘要： PROBLEM TO BE SOLVED: To improve the processing speed of a dispensing device by connecting a continuous rack in advancing direction and maintaining the interval between specimens at an equal interval. SOLUTION: Specimen erection parts H1-1-H5-1 for erecting a blood-sampling tube exist. The rear surface of a rack is in a shape for placing a tip surface RT. By pressing a rear rack R2 to both racks R1, the rear surface of the rack and the tip surface RT are connected. Distances L1,..., L4 between the specimen erection parts H1-1-H2-1 and a distance L5 between specimen erection parts H5-1-H1-2 are at equal distances (equal intervals). The pitch between the two nozzles of the dispensing device is equal to the distances L1-L5. The nozzle starts dispensing each two specimen from the first specimen of a parent rack to a child rack and continuos dispensing up to the fourth specimen by two dispensing operations. Since the distance L5 between the fifth specimen and the first specimen of the parent rack is equal to the pitch between nozzles, dispensing can be made simultaneously.

摘要： PURPOSE:To certainly pull out a rubber stopper, which is corked in a blood- collecting tube for blood test, to prevent troubles from occurring in the next process by a method wherein an automatic stopper extractor brings devices into operation after detecting the presence of the stopper to pull out the stopper with a stopper pressing bar and a claw. CONSTITUTION:An automatic stopper extractor consists of a rack transfer mechanism and a stopper extracting mechanism 2. The rack transfer mechanism is provided with a blood-collecting tube holding mechanism 7 which holds a blood-collecting tube 12 immovably at a specified position. A light emitting element 8 and a light receiving element 9 are installed facing each other as a detector to detect a central protrusion 16 of a stopper 17 that is corked in the blood-collecting tube 12. On the other hand, the stopper extracting mechanism 2 is provided with a handling part 10 with claws 11 which is moved to a position above the blood-collecting tube 12. When the output of the light receiving element 9 shows the presence of the stopper 17, the blood collecting tube 12 is held by the holding mechanism 7, and the stopper 17 is pressed by a stopper pressing bar and pulled up by the claws 11, so that the stopper 17 is pulled out.

摘要： PROBLEM TO BE SOLVED: To save space by unitizing the centering of a test tube and a chuck when automatically attaching a bar code label to the test tube. SOLUTION: A test tube 2 is positively and safely retrieved without being bound to an overall size of the test tube 2 by making the shape of a chuck part 10 a V-groove shape, enabling it to hold even during power failure by means of a reduction ratio of a ball screw 5, providing a built-in spring below a link spindle 9 of test tube 2 chuck part 10, and corresponding to a difference in diameter of the test tube 2. Moreover, a holding state is continuously maintained even during an abnormal time.

摘要： PROBLEM TO BE SOLVED: To feed nozzle chips in a fixed direction by successively controlling operation steps so as to regulate the direction of charged and stored nozzles chips, by automatically lining up a plurality of nozzle chips on a nozzle chip storage container, by mounting a plurality of nozzle chips from lined-up containers, and by making dispensation under dispensing instructions. SOLUTION: Nozzle chips dropped onto a buffer unit 9 from a hopper unit 1 are shifted onto a conveyer 3 by a suitable number, and are then fed onto a crawler unit 4 one by one. The unit 4 stores and transfers the nozzle chips one by one, and nozzle chips lined up horizontally, are dropped one by one onto a stocker unit 5, and are then lined up in an arbitrary number. The front ends of thus lined-up nozzle chips are aligned together being directed downward, and are dropped onto a chuck unit 6. The nozzle chips on the chuck units 6 are dropped and arranged in nozzle chip storage containers which are successively moved. When all chips are stored in the container 7, the container 7 is moved to a position where the chips are mounted by five at each time, and accordingly, sample liquid is sucked up by a required quantity instructed by a host computer.

摘要： PROBLEM TO BE SOLVED: To avoid increasing the length and the size of a rack transport system by associating multiple rack transport units including a main transport line and a reverse transport line with a single transport direction changing mechanism. SOLUTION: Multiple rack transport units 4, 5, 6 placed opposing to a transport direction changing mechanism 7 individually have main transport lines 4a, 5a, 6a and reverse transport lines 4b, 5b, 6b. A distance between first and second rack passages 7a, 7b formed parallel to each other on a turn table 77 on the transport direction changing mechanism is equal to a distance between the main transport line and the reverse transport line. The first and the second rack passages 7a, 7b are placed in an equal distance from a rotation center of the turn table 77. The turn table 77 can receive a specimen rack in one rack passage while a rack is loaded in the other rack passage.
