<P>PROBLEM TO BE SOLVED: To prevent recovery of an unreproducible article in a system for improving a recovery result of used consumables by imparting an incentive. <P>SOLUTION: A requester 6 requests recovery of the consumables by making access to a recovery center system (S302). The recovery center system confirms actually recovered consumables (S312), and imparts the incentive such as money to a requesting user in the case of a reproducible article. However, when an unreproducible reproduced article and the other company product are included in a recovery article, a database is updated by subtracting a predetermined value from the imparting incentive or an incentive stored to be imparted according to its kind and quantity (S313). A user is informed of the effect (S314). <P>COPYRIGHT: (C)2003,JPO |
