摘要： PURPOSE: To make an inspection efficiently by switching the quantity of transmission for a photographed image in accordance with a sample measuring time of a designated test specimen. CONSTITUTION: Dyed urine is led to a flow cell 4, a laser beam is irradiated 15 to the upstream section of a flow formed in a flat shape to detect scattered light, and grains are thereby detected 22. The grain detection thereby causes a flash lamp 1 to be lighted, and also causes the objective lens 5 of a microscope to form a grain image at an image forming position 6. The aforesaid image is photographed by TV camera 8 as a static image, and processed by photoelectric conversion so as to be stored in an image memory 25. The stored image is then processed 28, and transferred 34 to a display means 35 so as to be judged by specialists. In this case, a processing speed is selected out of 120, 80 and 60 specimens/hour in accordance with the condition of a specimen so as to be inputted into a key board 33. With no waiting time required for the speed of 120 specimens/hour, and with the waiting time of 15(30) seconds required for the speed of 80(60) specimens/hour, measurement is then started so as to be transferred at the time of completion. Therefore, the quantity of transmission for the speed of 60 specimens/hour is twice as much as that of 120 speciemens/hour, and inspection can thereby be made efficiently by switching the quantity of image transmission to meet the condition of the specimen.

摘要： PURPOSE:To realize an automatic liquid specimen analyzer capable of automatically discriminating to which specimen an obtained inspection result corresponds by detecting the condition thereof in the case where the specimen is not arranged at a light measuring position in the case and the like where a specimen supply part serves to fail in specimen supply. CONSTITUTION:A specimen presence detector is arranged in an automatic specimen supply part 15 and a pressure sensor for detecting whether a specimen 23 is grasped with a specimen grasping part 37 is set. A detection signal transmitted from the specimen presence detector and the pressure sensor is transmitted to a control part 51. Thereby in the case where the specimen fails to be taken out and grasped, a control part 51 serves to detect the condition thereof. Accordingly, discrimination is exactly and automatically performed to which specimen an inspection result obtained to detect it corresponds even if the specimen 23 is not arranged at a light measuring position of a measuring part 17 and no grasping occurs.

摘要： PURPOSE:To reduce a waste of a sample and a reagent by dispersing the reagent and a sample in a reaction container, and continuing to measure a sample which is already stirred even if a dispensation part or stirring part becomes abnormal and obtaining measurement data. CONSTITUTION:A sample cup 1 is installed on an inspected body rack 2, mounted on a rack conveyance device 3, and conveyed to the sample dispensa tion, and the sample is dispensed in the reaction container 6 from a sample dispensing probe 4 by a specific amount. Then the reagent is added from the reagent dispensation part and stirred by a stirring device 14 and when the they passes in the luminous flux emitted by a light source 15 at a light measure ment part, a multiwavelength photometer 16 detects the absorbance; and its luminous intensity signal is processed by a computer 19 and the concentration is measured. At this time, if the dispensation part or stirring part becomes abnormal, a reaction table 7 is so controlled that devices parts regarding rotat ing operation, measuring operation, and measurement data processing continue to operate. Thus, a sample having advanced to a light measurement point is measured without being discarded, and thus utilized effectively.

摘要： PURPOSE:To analyze samples of different liquid level heights without changing the max. descending amt. of a sample nozzle by generating the output of a fault detector when the sample nozzle is within an abnormal region. CONSTITUTION:Pulse signals are sent to a vertically moving motor 19 and the sample nozzle 5 starts descending when a start signal is inputted to a CPU 41. The number of pulses corresponding to the length of the 1st abnormal region 29 is set simultaneously in a register 43. This number and the number of the pulses sent to the motor 19 and counted by a pulse counter 43 are compared by a comparator 44. The CPU 41 closes a switch 45 to receive the signal of the fault detector 35 until both coincide. The CPU 41 sends the numerical value corresponding to the sum of the abnormal region 29 and the 1st normal region 32 to the register 43 to alternate the contents thereof and to hold the switch 45 opened to the next coincidence signal of the comparator 44 when the comparator 44 generates the coincidence signal of the counter 42 and the register 43. The signal from the fault detector 35 is thus shut off.
