The document creation software can store update information data representing document update information in a document file. A document file in which update information data is stored is transmitted from the personal computer 20 to the document file server 1.

  When the document file transmitted from the personal computer 20 is received by the document file server 1, update information data is extracted from the document file. The extracted update information data and the document file are transmitted from the document file server 1 to the mobile phone 30. In the mobile phone 30, the document represented by the document file and the update information represented by the update information data can be confirmed. Details will be clear from the following explanation.

  FIG. 2 is a block diagram showing an electrical configuration of the document file server 1.

  The overall operation of the document file server 1 is controlled by the CPU 3.

  The document file server 1 includes a display device 4, a clock 5 for measuring the access date and time of the mobile phone 30, a memory 6 and the like. In addition, the hard disk 7 in which the above document file is written, the hard disk drive 8 that reads the written document file or the like from the hard disk 7, the input device 9 such as a keyboard, and the memory A card interface 10 is also included. Further, the document file server 1 includes a communication circuit 11 for communicating with the mobile phone 30 and the like, a CD-ROM drive 12 and the like.

  5 to 7 are flowcharts showing the processing procedure of the document file communication system.

  In the personal computer 20, a document is created using document creation software, and the document is updated a plurality of times. A document file representing such a document is uploaded from the personal computer 20 to the document file server 1 (step 51 in FIG. 5).

  When the document file uploaded from the personal computer 20 is received by the document file server 1 (step 61 in FIG. 5), update information data stored in the document file is extracted (step 62 in FIG. 5). The received document file is stored in the document file storage area of the hard disk 7 of the document file server 1. The extracted update information data is stored in the update information table stored in the hard disk 7 (step 63 in FIG. 5).

  FIG. 8 is an example of the update information table.

  The update information table stores update information data stored in the document file as described above. The update information table stores update information data stored in all document files received by the document file server 1 without being generated for each document file. However, different update information tables may be generated corresponding to the document files.

  The update information table stores file names, update dates and times, processing contents, update contents, update positions, and the like. The file name is the file name of the document file from which the update information data is extracted. The update date / time is the date / time when the document was updated. The processing contents are contents of update processing such as deletion of a part of a document and insertion of a part of a document. The update content is a sentence itself such as a deleted sentence or an inserted sentence. The position indicates the position of the updated part in the document. When the document is updated, this position will deviate from the position of the updated document. Therefore, every time the document is updated, the position of the updated document will be rewritten.

  After the document file is uploaded from the personal computer 20 to the document file server 1, the document file is updated in the personal computer 20, and the updated document file is uploaded from the personal computer 20 to the document file server 1.

If the document represented by the requested document file can be displayed on the display screen of the mobile phone 30 (YES in step 68 in FIG. 6), the process in step 69 is skipped.

  Subsequently, among the last access date and time stored in the access information table, the last access date and time corresponding to the file names of the mobile phone 30 and the requested document file is updated (step 70 in FIG. 6). Further, an update information file is generated from the update information extracted from the update information table. This update information file has the same file name as the file name of the document file (if the document file is converted, the file name of the converted document file) and has a different extension. By confirming the file name, the document file and the update information file corresponding to the document file can be known.

  The converted document file that has been converted (if the document represented by the document file before conversion cannot be displayed on the display screen of the mobile phone 30) or the document file before conversion that is not converted (represented by the document file without converting the document file) The update information file is transmitted from the document file server 1 to the mobile phone 30 (step 72 in FIG. 6).

  When the converted document file or the pre-conversion document file and the update information file transmitted from the document file server 1 are received by the mobile phone 30 (YES in step 82 in FIG. 7), the document represented by the document file and the update information The update information represented by the file is displayed on the display screen of the mobile phone 30 (step 83 in FIG. 7).
