Abstract

An electronic paper system includes: a document data storage which stores document data; an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage; and a control apparatus which, when storing the document data in the document data storage, controls a method of storing the document data in the document data storage in accordance with a preset condition, and controls the storage of the link information in the memory of the electronic paper in response to the method thus controlled.

Claims

1. An electronic paper system comprising:

a document data storage which stores document data;

an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage; and

a control apparatus which, when storing the document data in the document data storage, controls a method of storing the document data in the document data storage in accordance with a preset condition, and controls the storage of the link information in the memory of the electronic paper in response to the method thus controlled.

2. An electronic paper system according to claim 1, wherein

the control apparatus uses the link information stored in the memory of electronic paper to control a method of storing a new, second document data in the document data storage.

3. An electronic paper system according to claim 2, wherein

the control apparatus merges the first document data stored in the document data storage with the new, second document data, and stores the merged data in the document data storage.

4. An electronic paper system according to claim 2, wherein

the control apparatus disables the access to the first document data by the link information, and stores the new, second document data in the document data storage to be accessible by the same link information.

5. An electronic paper system comprising:

a document data storage which stores document data;

an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage; and

a control apparatus which, in response to access to the document data storage, controls the display of the electronic paper to change the document image of the document data in accordance with a preset condition.

6. An electronic paper system according to claim 5, wherein

the control apparatus, in response to deletion of the document data from the document data storage, controls the display of the electronic paper to change the document image of the document data to an image indicative of the deletion of the document data.

7. An electronic paper system according to claim 5, wherein

the control apparatus, in response to storage of the document data in the document data storage, controls the display of the electronic paper to change the document image of the document data to an image indicative of the storage of the document data.

8. A control apparatus for an electronic paper system including a document data storage which stores document data, and an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage, the control apparatus comprising:

means for controlling a method of storing the document data in the document data storage in accordance with a present condition when the document data is stored in the document data storage; and

means for controlling the storage of the link information in the memory of the electronic paper in response to the method thus controlled.

9. A control apparatus for an electronic paper system including a document data storage which stores document data, and an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage, the control apparatus comprising:

means for obtaining a preset condition; and

means, in response to access to the document data storage, for controlling the display of the electronic paper to change the document image fo the document data in accordance with the present condition.

10. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function for controlling an electronic paper system including a document data storage which stores document data, and an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage, the function comprising the steps of:

controlling a method of storing the document data in the document data storage in accordance with a present condition when the document data is stored in the document data storage; and

controlling the storage of the link information in the memory of the electronic paper in response to the method thus controlled.

11. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function for controlling an electronic paper system including a document data storage which stores document data, and an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage, the function comprising the steps of:

obtaining a preset condition; and

controlling the display of the electronic paper to change the document image of the document data in accordance with the present condition, in response to access to the document data storage.

12. A control method for an electronic paper system including:

a document data storage which stores document data;

an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage; and

a control apparatus, the control method comprising the steps of;

controlling, with the control apparatus, a method of storing the document data in the document data storage in accordance with a present condition when the document data is stored in the document data storage; and

controlling, with the control apparatus, the storage of the link information in the memory of the electronic paper in response to the method thus controlled.

13. A control method for an electronic paper system including:

a document data storage which stores document data;

an electronic paper having a display that displays and retains a document image based on the document data in a no-power state and a memory that readably and writably stores link information enabling access to the document data stored in the document data storage; and

a control apparatus, the control method comprising the steps of;

obtaining a preset condition with the control apparatus; and

controlling, with the control apparatus, the display of the electronic paper to change the document image of the document data in accordance with the present condition, in response to access to the document data storage.
