JPS6426179A - Entering/leaving area managing device for radiant ray managing area - Google Patents

Abstract

PURPOSE:To contrive the simplification of an entering/leaving area operation by transmitting/receiving entering/leaving area information by an integrated circuit (IC) card provided on a radiant ray exposure measuring instrument. CONSTITUTION:An IC card is provided on a radiant rays exposure measuring instrument, and allowed to store a personal recognition symbol and a radiant rays exposure measured data being in the course of work. At the time of entering into a radiant rays managing area, an initial value of a radiant rays exposure data, and a personal recognition are inputted from an IC card input device 5, and area entry managing information inputted in advance from a management data input device 15 and a working environment radiant rays level input device 14 is displayed on an area entry display part 4. When the area entry condition is satisfied, an area entry gate 3 is opened, and also, the area entry managing information is inputted through an output interface 13. At the time of leaving from the area, various data are fetched to a computer 12 through an input interface, and by checking contamination, etc., whether it is allowed to leave from the area or not is decided, and a leaving area gate 8 is opened. In such a way, the entering/leaving area operation can be simplified, and also, the entering/leaving area managing information can be fed back to the IC card, and the practical use of information can be enlarged.
