<p>PURPOSE: To shorten latency by setting use reservation for plural use objects in an order managing device and allowing plural objects to simultaneously and parallely wait for in the device in a queuing mode set at respective objects. CONSTITUTION: An offerer requiring the use of objects 2 previously selects plural objects, e.g. 2a to 2c, required to be used and offers the use of the objects to the order managing device 3 through an input device 1. The device 3 accepts the offer of the use, issues an identification(ID) card 4 from the device 1 accepting the offer and manages the order of the accepted offer. When the offer is not accepted, negative acknowledge(NAK) to the objects concerned is executed and the disableness of use of the objects is reported through the device 1. When any one of objects offered from the offerer arrives at the offerer's order, a message indicating the usable state of the object is reported to the offerer by the use of the card number or the like of the ID card 4 through a display device 5. Consequently the objects 2 can be used without queueing up for use.</p> |
