2. Description of the Related Art In conventional analog broadcasting by television, the amount of information that can be transmitted per time is much smaller than the amount of information of digital broadcasting by BS digital broadcasting and CS digital broadcasting using recent broadcasting satellites and communication satellites. Was low. The distribution of electronic information by digital broadcasting is performed wirelessly using radio waves in the microwave band, and the amount of electronic information by the data distribution, including terrestrial digital broadcasting and broadband data distribution, is the same as that of conventional digital broadcasting. Compared with the means of broadcasting and communication, the number increases dramatically, and two-way communication is also possible.

[0003] However, if such electronic information is printed on a display medium such as paper so that it can be read, a large amount of paper is consumed. In recent years, there has been an increasing interest in environmental measures such as resource saving and recycling, and it is hoped that a display medium such as paper, which is being consumed in large quantities, can be used repeatedly so that it can be an alternative to information transmission means such as newspapers and magazines. ing.

Conventionally, as a method of repeatedly using a display medium, as disclosed in Japanese Patent Application Laid-Open No. H11-502950 and Japanese Patent Application Laid-Open No. 2001-500172, dyeing is performed with electrophoretic particles. The microcapsules containing the solvent are dispersed in a binder, and a thin-coated paper-like image display sheet is used to apply an electric field to the matrix from the first and second address electrodes sandwiching the image display sheet. When the electrophoretic particles move in the capsule and the electrophoretic particles come to the observation side, the color of the electrophoresis particles can be seen, and when they go to the opposite side of the observation side, the color of the solvent can be seen.
2. Description of the Related Art A reversible display image display sheet that displays and deletes an image in color is known.

[0005] However, microcapsules containing electrophoretic particles and a stained solvent are dispersed in a binder, and in a thinly coated paper-like image display sheet, rewritable information is input each time. Because of this, there is a problem that necessary information must be searched for, input, and displayed. Furthermore, it has a drawback that it is limited to applications such as display on a book type or a watch, and is far from being an alternative to information transmission means such as newspapers and magazines.

Then, the previous image disappears and the next image is displayed.

The display section 10 is made of rewritable electronic paper, and can display information one after another. Further, the display is displayed even after the application of the electric field is stopped after the application of the electric field is performed once. In other words, it has a display memory property, can save electricity during reading, and can be said to be a sheet-like display medium having high substitute characteristics of paper.

The genre of electronic information to be recorded on the recording section 7 can be set in advance. When the setting mode is selected with the operation button of the operation unit 9, the setting screen is displayed on the reversible display unit 10. Therefore, the operation unit 9 is operated by operating the operation button, and the setting is performed via the control unit 8. For example, when a genre such as politics, economy, sports, and cooking is set, the ID of the corresponding genre is recorded. With this setting, the ID of the set genre is compared with the packet ID in the header of the data-distributed electronic information data, and if they match, the corresponding electronic information is determined, and the corresponding electronic information is determined. Recording is performed on the memory of the recording unit 7.

The recording section 7 is composed of a RAM and an EEPROM, and a recording section having a large capacity memory can be applied. In addition, an external recording device such as a CD-RW, DVD, or HDD, or a personal computer or a PDA may be externally provided, and data recorded in these recording units can be displayed. The input unit 4 is a keyboard, scanner,
An external input device such as a digitizer can be connected.
