<p>PROBLEM TO BE SOLVED: To provide a control system for article to be retrieved which can retrieve and display a desired article to be retrieved quickly and easily with multiple purposes and high functionability and has a simple structure without providing an additional electronic circuit to an discriminating element fitted on the article to be retrieved and having inherent information. SOLUTION: In a file retrieval control system, a discrimination code detection part 8 detects the discrimination code of a discrimination plate 2 which has a discrimination display part 2a attached to an article to be retrieved placed on respective rack plates, and from the results of data processing based on the code detection signal, an optical element control part 7 controls light emitting of a plurality of color light emitting elements (red LED, green LED) through a control indication from a data processing control part 6 fitted on respective rack plates, and selectively-designates the discrimination display part 2a for each classification with different luminescent colors for visible display. The data processing control part 6 stores the storage number of the article to be retrieved, so in displaying the particular discrimination display part 2a, its operation is displayed on the host device side, or is indicated with communication interface.</p> |
