Patent number: 6959223Abstract: A user creates image data where the user optionally designs an arrangement and a size of each meter in a combination meter on a personal computer screen based on meter designing data DT1 including manufacturing conditions at a user-side meter designing section. Combination meter producing data DT2 is generated from the image data and sent to a combination meter manufacturing data processing section. The processing section derives meter manufacturing data DT3 from the meter producing data DT2. Consequently, the data processing section automatically sends out an order of manufacturing the combination meter to a manufacturer side. The manufacturer side assembles the combination meter according to the meter manufacturing data DT3.Type: GrantFiled: September 20, 2002Date of Patent: October 25, 2005Assignee: Yazaki CorporationInventors: Masaaki Ogasawara, Masahiro Muramatsu
