Abstract
In a production supervising system of a work, a wireless type production supervising data processing apparatus is mounted on the work. The wireless type production supervising data processing apparatus includes a wireless type interface unit, and an IC card. The IC card includes CPU, EEPROM for storing the production supervising data, ROM for storing the program data, and RAM capable of storing other data than the production supervising data. The wireless type interface unit includes antennas, a receiver, a transmitter, a demodulator connected to the receiver, and a modulator connected to the transmitter. During the production of the work, the production supervising data previously stored in EEPROM are read from the IC card and processed in the interface unit and thereafter transmitted from the interface unit toward the external data controlling apparatus.
