<P>PROBLEM TO BE SOLVED: To correctly manage a content image displayed on electronic paper by ensuring a content image erasure state of the electronic paper. <P>SOLUTION: Identification information of the electronic paper EP and identification information of a content displayed and held on the electronic paper are associated, and are recorded and managed in a management table 22. When rewriting the content (C#7003) displayed and held on the electronic paper EP into another content (C#7001), an image for erasure (an initial image) is intermediately written into the electronic paper EP so as to erase the original content (C#7003), and it is confirmed by image reading, and thereafter is rewritten into the content (C#7001). In a writing state of the image for the erasure, the management table 22 maintains the original content identification information (C#7003), and prevents discordance in the management table occurring in rewriting processing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
