  • Master ECR for interrogating the state and data contents of a slave ECR
    Patent number: 4771382
    Abstract: An electronic cash register system of the register-in-line type includes a master machine and a plurality of slave machines which communicate with the master machine. A state determination system is included in each of the slave machines for storing a state indicating signal which indicates whether a reset operation or a read operation has already been conducted to the transaction data registered in the slave machine. When the transaction data is transmitted to the master machine, the state indicating signal is also transmitted to the master machine. Accordingly, the operator of the master machine can monitor the operational states of the respective slave machines.
