<p>PROBLEM TO BE SOLVED: To prevent the lowering of the producibility caused by the generation of fault even in a case when the stock management data is disappeared, by restructuring the disappeared stock management data, by reading a tag by controlling a tag reading means when a carrier or a box is stocked, and successively scanning the stocker shelves. SOLUTION: Whether a carrier or a box is loaded on a stocker shelf 2 or not, is confirmed by a stock detecting sensor 4. In a case when the carrier is not found in the shelf 2, the detection is finished, and the detection of the next shelf is started, and in a case when the carrier is found in the shelf 2, a detecting signal is transmitted to a management computer 8. When an arm is extended to a specific position, a bar code of a tag is read by a reading sensor of a scanner 5, and is converted into a binary code by a convertor 6a, to be transmitted to the management computer 8. The management computer 8 confirms the lot information on the tag by a bar code signal, and one stock data is recovered. Then the stock.data file is restructured.</p> |
