2. Description of the Related Art In recent years, with the development of LAN, LAN
A variety of needs have been created by utilizing, and various proposals have been made to address these needs. Further, with the development of a document creating device (for example, a Japanese word processor), a more sophisticated document creating device has been proposed. For example, LAN
Proposals related to are: A work station having voice signal input / output means is connected to a LAN so that voice messages can be exchanged through the LAN (Japanese Patent Laid-Open No. 72252/1988).

Image data sent from an unspecified facsimile machine connected to a LAN can be given a document number and transferred to a workstation (Japanese Patent Laid-Open No. 2-94959). Further, there are the following proposals regarding the document creation device. When a key is not input within a certain time during document creation, the document is stored in a storage device and the power of the document creating device is turned off (Japanese Patent Laid-Open No. 63-289668).

[0004]

However, the LAN
When an operator works at a client terminal (workstation or the like) on a network, it is common for the operator to work at the client terminal away from the room where he normally works. for that reason,
When a voice message arrives at the workstation, even if the message is stored (answer message), the user has to bother to leave his / her seat in the room to the place where the workstation is installed and listen to the message. There was a hassle of having to do it. Also, the place where the facsimile machine is installed is
It is often installed in a place apart from the terminals on the LAN network. Therefore, if there is a facsimile transmission to myself, the work of the LAN network up to that point must be interrupted and the facsimile document must be taken to the place where the facsimile device is installed. . Also, if the document creation device is used alone (that is, it is used without being connected to a LAN system or the like) and the power is accidentally turned off, the document created up to that point is erased. There was an inconvenience.

Therefore, an object of the present invention is to provide a LAN capable of obtaining an answering machine message or a facsimile message during work in a room or work using a LAN terminal without interruption of the work up to that point. The purpose is to provide a system. Another object of the present invention is to provide a LAN system that prevents the document being created from disappearing even when the power is turned off while the document is being created by the document creating apparatus connected to the LAN.

According to a first aspect of the present invention, there is provided a server having an answering machine function and an ISDN terminal device, and a client terminal having a codec conversion function and a function for outputting a voice signal to a speaker. The voice message received by the server is sent to the LAN
The voice mail message is sent to the client terminal via the, and the voice message is output from the speaker of the client terminal. According to the second aspect of the present invention, a server having a G3 or ISDN facsimile function and a client terminal having at least an MH (Modified Huffman) decompression function are provided, and the server receives the incoming facsimile transmission, and the server transmits the facsimile transmission. The document is displayed on the screen of the client terminal, and the document on the screen of the client terminal is facsimile-transmitted via the server. According to a third aspect of the present invention, it is provided with a document creation device having a LAN interface, a server having a function of storing documents created by the document creation device, and a client terminal capable of transferring the documents stored in the server. When the power of the document creation device is turned off, the document being created is transferred to the storage function of the server and stored, and when the power is re-energized, the document stored in the server is transferred to the client terminal. It was constructed to be strict.

[0007]

In the LAN system according to the first aspect, the voice message received by the server is mailed to the client terminal and output as voice from the speaker of the client terminal. In the LAN system according to the second aspect, the incoming facsimile transmission is received by the server, and the server displays the facsimile transmission on the screen of the client terminal. At the same time, the document on the screen of this client terminal is transmitted by facsimile via the server. In the LAN system according to the third aspect, when the power is turned off while the document is being created by the document creating apparatus, the document being created is stored in the server.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a LAN system of the present invention will be described in detail below with reference to FIGS. First Embodiment As shown in FIG. 1, a LAN 100 is connected to first to nth client terminals 1 to n, and each client terminal 1 to
Each n has a speaker 1a, 2a, 3a to na, and has a voice synthesizing function by a codec.
A server 5 having a disk 6 for data storage is connected to the LAN 100, and an ISDN line 7 is also connected. That is, the server 5 has an ISDN interface 5a having an answering machine function.
The server 5 is ISD via the SDN interface 5a.
It is connected to the N line 7.

Next, the operation of the LAN system thus constructed will be described with reference to FIG. The ISDN interface 5a recognizes the other party's number, destination information, voice, etc. from the signaling information in layer 3 based on the data from the ISDN line 7. If the voice signal is included, the answering machine function is activated and voice data (codec-converted digital signal) from the other party is sent to the disc 6
Accumulate in. Next, the server 5 transmits the various information (partner number, destination information, voice, etc.) to each of the client terminals 1 to n by the mail function. Then, each of the client terminals 1 to n determines the above-mentioned various information and, if the information is addressed to itself, issues a data transfer request to the server 5.
In response to this request, the server 5 transmits the data stored in the disk 6 to the client terminal which made the request. This client terminal performs codec conversion on the data transmitted from the server 5, and outputs it as a voice signal from the speaker. When the voice output is completed, the client terminal issues a command to the server 5 to request deletion of the output data. The server 5, which has received this command, deletes the corresponding accumulated data.

Second Embodiment As shown in FIG. 3, 11-m client terminals 11-m are connected to the LAN 100. LAN 10
A server 14 having a disk 6 for data storage at 0
Is connected, ISDN line or public line 16
Are connected. That is, the server 14 is ISD
Facsimile interface 14a having N4 G4 facsimile function or public line G3 facsimile function
The server 14 is connected to the ISDN or the public line 16 via the facsimile interface 14a. It is assumed that any of the server 14 and the client terminals 11 to m is provided with MH, MR (Modified Read), and MMR compression / expansion functions.

Next, the operation of the LAN system thus constructed will be described with reference to FIG. Facsimile data transmitted via the ISDN or the public line 16 is transmitted to the facsimile interface 14a of the server 14.
Is received by and stored in the disk 6. Server 1
A line 4 adds some lines to the facsimile data and transmits the facsimile data to the client terminals 11 to m by a mail function. Each of the client terminals 11 to m receives the mail and displays the added facsimile data (decompressed image data when the client terminal has a decompression function) on the screen.

With this display, if the facsimile data is addressed to itself, a data transfer request is issued to the server 14. In response to this transfer request, the server 14 transfers the facsimile data to the client terminal. The client terminal displays the facsimile data on the screen and issues a deletion request to the server 14 if not necessary.
The server 14, which has received the deletion request, deletes the facsimile data stored in the disk 6.

Third Embodiment As shown in FIG. 5, the LAN 100 includes a Japanese word processor 21 having a LAN interface 21a and a second word processor.

Next, the operation of the LAN system thus constructed will be described with reference to FIG. It is assumed that a document is being created by the Japanese word processor 21 having the LAN interface 21a (step 1). Server 24
Always monitors whether the document has been updated (step 2). If the document has been updated (step 2; Y), the document is saved in the internal memory (not shown) of the server 24 (step 3). If the word processor 21 is accidentally turned off (step 4), the server 24 turns off the power.
Recognize via N100 (no response) (step 5).
By this recognition, the data saved in the internal memory at that time is stored in the disk 6 (step 6).

Eventually, the server 24 recognizes the re-energization of the word processor 21 which is the client terminal (in this case, there is a communication response) (steps 7 and 7a). Then, the server 24 transfers the document data stored in the disk 6 as described above to the Japanese word processor 21 (step 8), and after the transfer, erases the stored document data (step 9). By the transfer of the document data, the Japanese word processor 21 displays the document data when the power is off (step 10). That is, delete the document by L
It is prevented as an AN system.

[0016]

As described above, according to the first aspect of the present invention, since the telephone message to the user can be heard regardless of which terminal of the LAN system is working, the workplace and the living room are separated from each other. You can listen to the message without leaving your seat and improve your work efficiency. Further, according to the second aspect of the present invention, any terminal of the LAN system can see the facsimile document to the user on the terminal screen, which saves the trouble of taking the facsimile document to the facsimile device. Since the document can be viewed on the screen, it can be made paperless. According to the third aspect of the invention, even if the power is turned off during document creation or if the user forgets to save the document, the document remains in the LAN system until the next startup. Documents can be protected.
