Abstract
The automatic analyzer relating to the invention is characterized in that since drive and control of the automatic analyzer and storage of the measuring data are realizable on the IC card, operability of such kind of automatic analyzer is sharply simplified, the system can be miniaturized substantially to a low cost, moreover, in case the automatic analyzer gets damaged, portion and cause of the damage can be found easily and quickly.
Claims3
A multi-item automatic analyzer which comprises:
- a reaction cell table holding a plurality of reaction cells;
- means for repetitively rotating said table for moving each cell from a sampling position successively through a reagent dispensing position and an optical measuring position to a washing position;
- a sampling mechanism at said sampling position for placing a sample to be analyzed into a reaction cell;
- a reagent dispensing mechanism at said reagent dispensing position for dispensing a reagent into a reaction cell;
- an optical measuring mechanism at said optical measuring position for making optical measurements of samples in the reaction cells passing said optical measuring position;
- a washing mechanism at said washing position for washing reaction cells;
- a control device connected to said table rotating means, said sampling mechanism, said reagent dispensing mechanism, said optical measuring mechanism and said washing mechanism for operating said means and said mechanisms for carrying out a desired analysis on the respective samples in the respective reaction cells;
- an initiating IC card processing means for reading a predetermined analysis operation for a particular sample to be analyzed which has been stored on an initiating IC card which is insertable into said initiating IC card processing means;
- a memory IC card processing means for recording data on a memory IC card which is insertable into said memory IC card processing means;
- said initiating IC card processing means being connected to said control device for causing said control device to control said table rotating means and said mechanisms to carry out the predetermined analysis and being connected to said memory IC card processing means for recording the predetermined analysis operation on a memory IC card;
- and
- said memory IC card processing means further being connected to said control device and said optical measuring means for recording the actual analysis operation carried out by said analyer and the results of the optical measurements on the same memory IC card.
