Publication number: 20020178219Abstract: When a client needs to repair an apparatus, a person in charge for transportation in a sales company visits the client to receive the apparatus. The sales company repairs the apparatus. When the sales company cannot repair the received apparatus, the sales company commissions the apparatus to a third party. The sales company returns the repaired apparatus to the client. A system for managing this service has a database which registers information on apparatuses held by said client even for those apparatuses which are to be repaired at different sections; and a server which accepts a repair request made by each client, acquires information on the apparatus to be repaired by referring to said database and executes a processes of receiving the apparatus, repairing the apparatus, and returning the repaired apparatus to said client.Type: ApplicationFiled: May 24, 2002Publication date: November 28, 2002Inventors: Kazutoshi Iyonaga, Akira Mizuguchi, Emi Suzuki, Yoshiyuki Miyashita, Akira Hori
