PURPOSE:To reduce the load of processing and to improve processing speed by transmitting commodity data corresponding to a commodity data transmission request outputted from any one of electronic registers to a store processor to all the electronic registers. CONSTITUTION:Plural electronic registers 2 to be commodity data processing terminals are connected to one store processor (master file server computer) 1 through a communication line. When a commodity data transmission request is outputted front a commodity data transmission requesting means in any one of the registers 2 to the processor 1, commodity data corresponding to the request are transmitted from a commodity data transmitting means in the processor 1 to all the registers 2. The commodity data are stored in a commodity file by a commodity data storing means in each register 2. Thereby, the commodity data are quickly accessed, the number of commodity transmission requests to the processor 1 can be reduced and the communication volume of the communication line is reduced. |
