CONSTITUTION:A transaction window terminal equipment 1 sends out communication data containing transaction window data through a loop-like communication circuit 5 at every prescribed period. Each transaction participating terminal equipment 6-1 - 6-L sends out successively communication data obtained by adding necessary transaction information to communication data received from the terminal equipment of the previous stage through the loop-like communication circuit 5 to the terminal equipment of the post-stage through the loop-like communication circuit 5, respectively, by which communication related to the transaction information is executed between the transaction window terminal equipment 1 and each transaction participating terminal equipment 6-1 - 6-L which participates in the transaction. In such a way, the automatic transaction for determining the cost and the quantity at every transaction item between plural transaction participants and a transaction window device 7 is executed in parallel in plural transaction windows, as well, and also, the processing on a first-come-first-served basis of bidders can also be executed.</p> |
