Abstract: In the present invention, layout information about each screen layout is separated into a plurality of display elements, and is stored in a plurality of databases for the respective display elements in association with a language selection flag. The plurality of databases include an alignment/progression database and a component position database. The alignment/progression database stores alignment information and progression information. The component position database stores component position information. A controller acquires layout information appropriate to the language selection flag from each database, and controls a display device such that display information is displayed based on the acquired layout information.
