Abstract

PURPOSE:To make the needed data-fetch time of each terminal equipment nearly equal by sending out fixed data from CPU while regarding as a representative terminal the terminal which sent out a data-fetch request signal after all the others in data receiving and transferring of the distribution industry. CONSTITUTION:Terminal equipments POS#1-POS#n, multi-connected to a circuit extending from CPU, are provided with the function of generating request signal IPL for fetching data and while CPU transfers fixed data to the specific terminal which generated the request signal, other terminals fetch the fixed data from CPU simultaneously. In this case, CPU is provided with method FLI of selecting the terminal equipment which is the last to send out request signal IPL among terminals generating IPL by the final time when data of fixed length are transferred. Then, the terminal equipment selected by method FLI is regarded as a representative terminal to send the next fixed data.
