ABSTRACT:
An electronic cash register system includes a plurality of electronic cash registers interconnected by a common transmission line, and each of the electronic cash registers includes an information register device for registering flag information which "validates" or "invalidates" registration of each individual cashier as a register operator. Each of the electronic cash registers also includes a memory for storing the flag information, and an information transmission control device for controlling transmission of the flag information to the other electronic cash registers, when flag information is updated. Each of the electronic cash registers stores the flag information in its memory, when updated, and transmits, at the same time, the same flag information to the other electronic cash registers interconnected on the common transmission line. Each of the electronic cash registers receives the flag information to update the flag information stored in its memory and references the stored flag information so as to control the "validity" or "invalidity" of registration of the cashier as a register operator on the basis of the stored flag information.
