Abstract

An apparatus and method for information processing in a network system providing shared folders across a plurality of information processing apparatuses (personal computers) via network. A shared folder management table contains the IP addresses, identifiers of the personal computers, the names of shared folders, and the number of times or attempts to transmit data, etc. Searching of the shared folders is performed at given intervals of time and a search result is compared with the last search result. Based on the search result, a new management data founded is registered in the management table. If a destination personal computer remains inaccessible longer than predetermined time, management data of such personal computers are deleted from the management table.

Claims

1. An information processing apparatus, comprising:

a memory unit which stores a shared folder management table which contains information about a plurality of shared folders and states of a plurality of information processing apparatuses being associated with the shared folders, wherein each of said shared folders stores image data therein and is shared by one or more of the plurality of information processing apparatuses connected to a network;

a search controller which executes searching of said shared folders;

a comparator which compares shared folders of a present search with those of a last search;

an updating controller which updates said states of the information processing apparatuses in said shared folder management table based on present states of the information processing apparatuses determined from the information about shared folders stored in said shared folder management table and a result of the comparison made by said comparator; and

a display unit which displays updated states of the information processing apparatuses;

wherein said states of a plurality of information processing apparatuses in said shared folder management table include a power ON/OFF state of each information processing apparatus;

said updated controller updates the power ON/OFF state of each information processing apparatus based on present ON/OFF states of the information processing apparatuses determined from the information about shared folders stored in said shared folder management table and the result of the comparison made by said comparator; and

said display unit displays updated states of information processing apparatuses in a manner according to the updated power ON/OFF state of each information processing apparatus.

2. The information processing apparatus according to claim 1, further comprising:

a document reader which reads a document, and outputs image data; and

a communication controller which transmits the image data to said shared folders.

3. The information processing apparatus according to claim 1, wherein said search controller executes the shared folder searching at intervals of a first predetermined time.

4. The information processing apparatus according to claim 3, wherein said updating controller changes the power ON/OFF state of an information processing apparatus into OFF state when a shared folder, which is stored in said shared folder management table associated with the information processing apparatus, was found by the last search but is not found by the present search.

5. The information processing apparatus according to claim 1, further comprising:

a selection controller which allows selection of a destination to which image data is transmitted,

wherein, when said destination is selected, said display unit displays the updated states of the information processing apparatuses.

6. A method for information processing which is used to handle information about a plurality of information processing apparatuses interconnected by a network, said method comprising:

searching a plurality of shared folders stored in a memory unit which stores a shared folder management table which includes information about the shared folders and states of a plurality of information processing apparatuses having the shared folders, wherein each of said shared folders stores image data therein and is shared by one or more of the plurality of information processing apparatuses connected to a network;

comparing shared folders obtained by a present search with those of a previous search;

updating said states of the plurality of information processing apparatuses in said shared folder management table based on present states of the information processing apparatuses determined from the information about shared folders stored in said shared folder management table and a result of the comparison; and

displaying the states of the information processing apparatuses in a manner according to the updated states thereof

wherein, when states of the plurality of information processing apparatuses in said shared folder management table include a power ON/OFF state of each information processing apparatus, the power ON/OFF state of each information processing apparatus is undated based on present ON/OFF states of the information processing apparatuses determined from the information about shared folders stored in said shared folder management table and the result of the comparison and displayed on the display unit in a manner according to the undated power ON/OFF state of each information processing apparatus.

7. The method for information processing according to claim 6, further comprising:

reading a document by a document reader and output the image data; and

transmitting image data to said shared folders.

8. The method for information processing according to claim 6, wherein shared folder searching is executed at intervals of first predetermined time.

9. The method for information processing according to claim 6, wherein, the power ON/OFF state of the information processing apparatus is changed into the OFF state, when a shared folder was found by the last search but is not found by the present search.

10. The method for information processing according to claim 6, further comprising:

selecting a destination to which image data is transmitted,

wherein, when said destination is selected, said display displays the states of the information processing apparatuses.

11. The information processing apparatus according to claim 5, wherein said search controller executes the shared folder searching at intervals of a first predetermined time when said destination is not selected, and executes the shared folder searching at intervals of a second predetermined time shorter than the first predetermined time when said destination is selected.

12. A method for information processing according to claim 10, wherein said shared folder searching is executed at intervals of a first predetermined time when said destination is not selected, and said shared folder searching is executed at the intervals of a second predetermined time shorter than the first predetermined time when said destination is selected.
