<P>PROBLEM TO BE SOLVED: To provide a method of managing log-in history by which it is easily confirmed when and which injection molding machine a specific operator logs in. <P>SOLUTION: The authentication of the operator in the injection molding machine (1) is performed by the identification number (16) read from the ID card (14) via a radio communication apparatus (11). When the authentication is successively performed, the log-in history is recorded in the log-in history file (17) in the ID card (14). The log-in history comprises a time when the log-in is carried out and a machine number specifying the injection molding machine (1). Accordingly, when the log-in history file (17) in the ID card (14) is browsed, it is confirmed when and which injection molding machine the operator logs in. <P>COPYRIGHT: (C)2012,JPO&INPIT |
