Pos terminal unit

Abstract

Abstract PURPOSE: To correctly store the transmission data in POS terminal unit through the separation into on-line and off-line, by providing the memory directly coupled to the transmission line and storing the data in synchronizing with the data transmission via the transmission circuit. CONSTITUTION: The transmission line 4 is connected via the center side unit and the transmission line 5, the operation control circuit 2 is connected to the transmission circuit 4, and further, keyboard 1 inputting the data via the circuit 2, display unit 3, and the memory 61 providing the on-line subtotal section storing the data transmitted to the center side unit and the off-line subtotal section storing the data not transmitted to the center side unit, are connected. Further, the printer 7 printing the data of the memory 61, and the memory 62 in synchronizing with the data transmission via the circuit 4 and storing the data connected to the circuit 4 are provided, allowing the content of memory of both memories 61,62 to be addition and subtraction in the operating circuit 8. Further, the POS terminal unit separates the transmission data into on-line and off-line, and they are correctly stored in the memory 61. COPYRIGHT: (C)1980,JPO&Japio
