ABSTRACT:
A production process control system includes a plurality of terminal devices and a central device connected to the terminal device. Each of the terminal devices has at least an element for counting the amount of work done and generating a corresponding output, an element for entering a worker identifying code, an element for transmitting the counted output and the entered worker identifying code to the central device and an element for providing an output cancel signal by which, in conjunction with the counted output, a current output value is updated. The central device at least has an element for performing communications with each terminal device and an element for storing the output and the worker identifying code transmitted from the terminal device as associated with each other. In one aspect of the invention, there is provided in a terminal device a bar code reader for reading a bar code recorded on a medium, a bar code reader withdrawal detecting switch, and an alarm that acts when no input is received from the bar code medium over a predetermined lapse of time after detection of a bar code reader withdrawal.
