Abstract

An information display 1 according to the present invention has an information carrier 10 including a storable display panel 14 separate from a processing unit 20 including a battery 27, and in the case where there is a need to perform a process such as updating or manipulating information displayed on the display panel 14, it is possible to perform a desired process by connecting the processing unit 20 to the information carrier 10. For that reason, it is possible, in normal use, to separate components other than those for maintaining “display” which is a fundamentally required function for a display close to “paper” from the information display 1. Therefore, it is possible to realize the information display having convenience capable of replacing the paper.

Claims

1. An information display including a display section having a function of keeping a display state nonvolatile, wherein:

the display section is comprised of a unit separate and detachable from at least one nondisplay unit having a predetermined function other than the function of keeping display contents nonvolatile; and

the units are capable of mutually cooperative operation.

2. The information display according to claim 1, wherein the display section is comprised of a storable display capable of keeping a display state without supplying power.

3. The information display according to claim 1, wherein the display section includes a non-storable display requiring the power to keep the display state and a display keeping power supply for supplying the power to keep the display state.

4. The information display according to claim 1, wherein the nondisplay unit is a unit having a display processing function of generating display data in a form to be displayed on the display section from data as a display object and a function of supplying the power for rewriting the display contents on the display section.

5. The information display according to claim 1, wherein the nondisplay unit is a unit having the display processing function of generating the display data in the form to be displayed on the display section from the data as the display object and a unit having the function of supplying the power for rewriting the display contents on the display section.

6. The information display according to claim 1, wherein it has a storage section for holding the data as the display object nonvolatile on the unit comprising the display section.

7. The information display according to claim 1, wherein it has the storage section for keeping the display data in the form to be displayed on the display section generated from the data as the display object nonvolatile on the unit comprising the display section.

8. The information display according to claim 1, wherein at least one of the unit comprising the display section and the nondisplay unit is configured as sharable by the nondisplay unit or the unit comprising the display section of another information display.

9. The information display according to claim 1, wherein the unit comprising the display section has an instruction input section for inputting an instruction to the information display by a predetermined input operation, and the nondisplay unit becomes an operating instrument for performing a predetermined input operation.
