Patent ID: 7766232

Claim:
A record management system that manages an operation record for a chemical, comprising: an IC tag that is attached to each container for holding the chemical; an IC tag terminal that reads data from and writes data to the IC tag; and a record management apparatus that manages record information of the chemical; wherein: the IC tag terminal includes: a reading unit that reads from the IC tag a chemical ID for identifying the chemical held in the container to which the IC tag is attached; a terminal side accepting unit that accepts an entry of an operational description for the chemical from a predetermined operational description for the chemical and accepts from an operator, via an entry form screen that accepts an entry of characteristic information of a chemical that is an object of an operation corresponding to the operational description, an entry of the characteristic information; and a terminal side sending unit that sends to the record management apparatus the chemical ID read by the reading unit and operation information including the operational description and characteristic information for the chemical accepted by the terminal side accepting unit; the record management apparatus includes: a mass update record storing unit that stores a mass update record of each chemical having the chemical ID; a composition storing unit that stores composition information including a chemical ID of a chemical constituting each chemical having the chemical ID; a chemical ID correspondence storing unit that stores a correspondence between a new chemical ID and an old chemical ID, wherein the old chemical ID is assigned to a previous state of the chemical before the operation corresponding to the operational description is performed thereon and the new chemical ID is assigned to a subsequent state of the chemical after the operation corresponding to the operational description is performed thereon; a management apparatus side receiving unit that receives the operation information from the IC tag terminal; and an updating unit that updates the chemical ID correspondence storing unit according to the operation information received by the management apparatus side receiving unit, wherein updating the chemical ID correspondence unit comprises replacing the old chemical ID with the new chemical ID; and the IC tag terminal further includes: a terminal side receiving unit that receives the new chemical ID from the record management apparatus; and a writing unit that writes the new chemical ID received by the terminal side receiving unit to the IC tag attached to at least one of an inputting side container and a receiving side container.
