Transaction control system having a time delay adjustment transmission mechanism
First Claim
1. A transaction control system, having a time delay adjustment transmission mechanism, comprising:
- a center computer; and
a plurality of terminal devices connected through communication circuits to said center computer,said center computer includingtransaction information transmission means for transmitting transaction information simultaneously to the plurality of terminal devices through the communication circuits; and
transaction request receiving means for receiving transaction requests sent by the terminal devices through the communication circuits, andsaid plurality of terminal devices respectively includingadjustment time storage means for storing an adjustment time determined on the basis of the difference between the transmission time needed for exchange of information with the center computer and a reference time which is the reference of the transmission time;
transaction information receiving means for receiving transaction information sent by the center computer;
transaction information display control means for supplying transaction information received by said transaction information receiving means when the adjustment time stored in said adjustment time storage means has elapsed from the time point of its receipt;
transaction information display means for displaying the transaction information that is supplied by the transaction display control means when the adjustment time has elapsed from the time point of its receipt;
transaction request input means for inputting transaction requests; and
transaction request transmission means for transmitting to the center computer a transaction request input by said transaction request input means when the adjustment time stored in the adjustment time storage means has elapsed from the time point of its input.

Abstract
A transaction control system is disclosed wherein a center computer is connected through communication circuits with a plurality of terminal devices and wherein the users of the terminal devices do not suffer disadvantages in dealing produced by differences in transmission time with respect to the center computer. With this transaction control system, prior to the ordinary processing, the transmission time required to effect information transmission between the center computer and the various terminal devices is measured. Using the result of this measurement, an adjustment time is then set in each terminal device such as to make the transmission time coincide with a reference time. When in receipt of transaction information, each terminal device displays this transaction information after the lapse of the adjustment time after the time-point of its reception. And when a transaction request is input at each terminal device, this transaction request is transmitted to the center computer when the adjustment time has elapsed after the time-point of its input.
