PURPOSE:To eliminate the necessity of a developed security function and to simplify a system by storing production management data in a storage means independently of data output and preventing the disappearance of the production management data even when the abnormality at the production management part is generated, and a production managing part and a terminal equipment part are disconnected. CONSTITUTION:When a key input part 12 is operated, key input process, sing corresponding to a depressed key is executed. When a command is received from the host computer, host command processing is executed. In each timer interruption, a control device 20 acquires data inputted through a parallel input part 21 or an RS232C interface 23, and when valid data are included in the acquired production management data, the data are processed stored in a data storing part 26. The data are left in the data storing part 26 until an erase request is inputted from the host computer even after transmitting the data to the host computer by a request from the host computer. |
