[origin: EP0405594A2] An electronic cash register system includes: a parent electronic cash register (11) provided with a first control device (25) and a first memory (16) for registering a transaction data inputted thereto; a quasi-parent electronic cash register (12) provided with a second control device (26) and a second memory (16) for registering a transaction data inputted thereto; a child electronic cash register (13) provided with a third control device (27) for registering a transaction data inputted thereto; and a line (14) for communicating and registers to one another. The first, second and third control devices accomplish a mutual communication between the registers through the line and controlling the registers so as to store the data registered by the parent, quasi-parent and child registers into the first and second memories respectively when the parent register operates normally, store the data registered by the quasi-parent and child registers into the second memory when the parent register becomes inoperative, and transfer the data stored in the second memory to the first memory after the parent register is recovered to operate normally.
