  • Patent number: 6042786
    Abstract: An object of the present invention is to provide a small and compact analytical apparatus. An input/output device for directing the analytical apparatus and displaying analytical results and operation conditions is detachably provided on a body of the apparatus. Since the input/output device can be fixed to an upper position of the body, the apparatus saves space and can be placed on a desk. The analytical apparatus includes a sample disk and a reagent disk. The diameter of the reagent disk is greater than that of the sample disk, and both disks are arranged at the front of the apparatus so that the center of the sample disk is nearer the operator side than the center of the reagent disk. Therefore, the whole arrangement is compact, and the apparatus itself is compact.
