The model is equipped with a memory reception function and a transfer function. When the two fax machines receive image data from other fax machines, they store the information in the internal memory instead of printing it on paper, and then the pager always carried by the recipient who uses the fax machine. (Hereinafter referred to as "pager") is notified that image data has been transmitted. When the pager knows that the image data has been transmitted, the recipient sends a fax from the other fax machine that has sent the above notification to the fax machine that sent the notification, and performs remote control using the tone dial. To the nearest FAX,
Since the content of the transmitted information can be quickly obtained, the sender who wants to transmit the information by FAX does not need to be careful about the schedule and the current position of the receiver.

[0004]

However, in the above-mentioned conventional technique, the contents of the image data can be promptly obtained unless the FAX is installed in the vicinity of the recipient who is notified of the transmission of the image data by the pager. There was a problem that it could not be done. Also, since the pager's notification content is only that the image data has been transmitted, it is impossible to judge in advance whether or not it should be read immediately depending on the importance of the content of the image data. If you are notified by a pager while waiting to communicate information about a critical issue, even if the image data communicated is information about another less important issue, you can interrupt your work in progress. Nearest FA
There is a problem that X is found and the above-mentioned image data transfer operation is performed.

Therefore, an object of the present invention is to solve the above-mentioned problems, and upon receiving a notification that the data has been transmitted to the receiver, the receiver can immediately confirm the contents of the data on the spot. The purpose is to provide such a data delivery system.

Embodiments of the data delivery system of the present invention will be described in detail below with reference to the drawings. In addition, in the following description, from a general FAX to a portable information terminal device (hereinafter, "PD
A ”: Abbreviated as Personal Digital Assistant)
The description will be given only in the case of transmitting the X image data, but the data targeted by the present invention is not limited to this.
For example, graphic data, audio data, etc. can be the target.

FIG. 1 is a block diagram showing the overall configuration of a basic embodiment of the data delivery system of the present invention. In the figure, the FAX signal 1011 transmitted by the FAX 1010 is
After passing through the general public line 1020, it is input to the communication server (hereinafter, abbreviated as “CS”) 1040 via the line I / F 1030. The CS 1040 sends the FAX signal to a hard disk drive (hereinafter abbreviated as “HDD”) 1050 installed in the CS 1040 by FAX.
The data 1051 is accumulated and saved.

Next, the CS 1040 uses the line I / F 103.
Pager 1070 connected to PDA 1100 designated as the destination via 0 and the general public line
Notify the recipient of the FAX by a message. PDA1
100 receives this message as a digital signal from pager 1070 and notifies the user of PDA 1100 of FA.
Notify that X has arrived. Finally, the PDA 1100 calls the CS 1040 using a personal handy phone system 1090 (hereinafter abbreviated as “PHS”), which is a type of mobile phone connected to the PDA 1100, automatically or according to a user's instruction. Line (1091-
1081-1022-1032) are connected. And
The FAX data 1051 transferred from the CS 1040 is received through this line.

FIG. 2 is a diagram showing a schematic procedure for a user who is moving while holding the portable information terminal device shown in FIG. 1 to obtain FAX image data, and FIG.
Indicates a state in which a user of the PDA 2040 is riding in an automobile 2010 and is moving. At this point CS2000 is F
Upon receiving the AX signal, the CS2000 receives the PDA2040
The pager 2020 connected to is notified of the arrival of the fax by a message. Although the PDA 2040 can know the arrival of the FAX by receiving this message, the PDA 2040 has the disadvantage that the communication cannot be performed while the PHS 2030 is moving, so the PDA 2040 cannot know the FAX arrival through the pager 2020. Even if it is possible, FAX data cannot be immediately received using the PHS2030.

FIG. 2B shows a state where the automobile 2010 is stopped. At this time, since the PDA 2040 has stopped moving, the PHS 203 connected to the PDA 2040 is stopped.
It is possible to call CS2000 from 0,
FAX data can be received by connecting the CS 2000 and the line 2031.

FIG. 2C shows that the wireless communication equipment connected to the PDA 2040 is not a pager or PHS,
Cellular radio 2 that enables wireless communication even while on the move
The case is 050. In this case, car 20
CS2000 to PDA20 even if 10 is moving
It is also possible to notify the 40 of the arrival of the FAX via the cellular radio 2050 and to transmit the FAX data using the same line as it is.

The difference between FIGS. 2 (a) and 2 (b) with respect to FIG. 2 (c) is that a pager and a PHS are used as radio communication equipment instead of a cellular radio.
The PHS has a drawback in that it cannot receive FAX data while moving, but has a feature that it is far more advantageous in terms of line usage charge and battery life during wireless communication. However, since nothing can be received while moving, a pager with a low running cost is used to notify the PDA of a message informing the arrival of the FAX in advance. Then, when the environment in which the PHS can be used is reached, a call can be made to receive FAX data.

FIG. 3 is a block diagram showing the overall construction of an embodiment in which a plurality of communication servers are provided in the data delivery system of the present invention. The area where the PDA is used extends over a wide area, and a plurality of CSs are provided at various places in the area. FIG. 6 is a configuration diagram for explaining an operation in the case where are distributed. A portion of the commonly used FAX 3000 that transmits FAX data to the CS 3050 using the general public line 3010 is the same as that in FIG. 1, and therefore description thereof will be omitted here, but in the present embodiment, a case where a plurality of CSs exist. Is shown. Specifically, for example, the FAX 3000 sends a FAX to the CS3050 installed in the Tokyo area,
This is the case when the user of the PDA 3080 designated as the destination is in the Ibaraki district. In the case of the embodiment of FIG. 1, the CS in the Tokyo area was directly connected to the PDA in the Ibaraki area by using a general public line, but in the case of the present embodiment, a company constructing the system is A plurality of CSs are installed all over the country, and the CSs are mutually connected using an intra-company network 3090 which is a line drawn by the company. Since this LAN 3090 is originally drawn by a company, the usage cost of this line is not proportional to the usage time, and it can be considered that the line usage fee is basically free.

By using the in-company network 3090, the CS 3050 installed in the Tokyo area can be used for FAX.
The message notifying the arrival and the FAX data itself are transmitted to the CS3070 installed in the Ibaraki area. C
S3070 accesses the general public line 3010 through the line I / F 3030, and is a PDA located in the same prefecture.
A message notifying that the FAX has been received is sent to the 3080, and the FAX data itself is also sent. This will allow faxes to be sent to PDAs that are known to be in remote areas.
Even when transferring data, FAX data with a large amount of data can be transferred at a lower cost by effectively using the company's own internal network without using expensive general public lines as much as possible. be able to.

FIG. 4 is a block diagram showing the overall configuration of an embodiment in which a cellular radio is attached to a portable information terminal device in the data delivery system of the present invention. In FIG. 1, the part of the generally used FAX 4000 that transmits FAX data to the CS using the general public line 4010 is shown in FIG.
Therefore, the description is omitted here. In this embodiment, P is assigned to the cellular radio 4060 which is a mobile communication device.
DA4070 is connected. Cellular radio 4060
As described with reference to FIG. 2C, communication is possible even while moving, and both reception and transmission can be performed while moving. When the CS 4030 receives the FAX signal, the CS 4030 accesses the general public line 4010 via the line I / F 4020, and further P through the cellular radio base station 4050.
The cellular radio 4060 connected to the DA 4070 is called to transfer a message informing that the FAX reception has been received. At this point, since the CS 4030 and the PDA 4070 are already connected to the bidirectional line, the user of the PDA 4070 confirms the message notifying that the FAX has arrived, and at the same time, sends the FAX data 4041 stored in the HDD 4040 of the CS 4030 to the PDA 4070. A transfer request can be made to the CS 4030 to be sent to. As a result, in the PDA4070, CS4030
FAX data received by can be ordered immediately on the spot.

In common with FIG. 1, the FAX is not directly transmitted to the PDA, but the CS is interposed so that the PDA telephone is busy, the PHS is moving, and the battery is in a down state. Even in a situation where communication is not possible, such as in some cases, the FAX can always send a PDA as a destination, and the PDA can operate whenever the wireless communication equipment installed in the PDA becomes operational. C
FAX data can be ordered from S.

FIG. 5 is a diagram showing an example of the contents of transmission data transmitted from the FAX to the portable information terminal device via the communication server. Message data is transmitted from FAX to CS in the following order of CS to P
Sent to DA.

The sender FAX makes a telephone call to the general public line exchange to send the FAX. Specifically, send the telephone number of the CS to receive to the exchange,
Make a telephone line connection to and from. The signal format is tone or dial pulse.

The FAX is the I of the destination PDA that actually tries to send the FAX image data to the CS.
Send the D number. The signal format at this time is a telephone tone signal here. The calling condition is that CS is P
The CS issues a carrier signal indicating that it can receive the DA ID number.

The FAX sends a digital signal, which is FAX image data, to the CS. This is the FAX signal itself which is normally used. The CS receives the digital signal forming the FAX image data, and stores and stores it in the HDD provided therein.

The CS sends the pager's calling telephone number to the switch to send a signal to the pager connected to the destination PDA.

The CS sends a message indicating that the FAX has been received to the destination PDA via the pager. The signal format at this time is a digital signal representing a character string that the pager normally recognizes.

The destination PDA is C for calling CS.
Send the telephone number of S to the exchange and connect the telephone lines of PDA and CS.

The destination PDA sends a request command to the CS to send the FAX image.

Upon receiving this request command, the CS transfers the FAX image data stored and stored in its own HDD to the PDA of the transmission destination.

FIG. 6 is a diagram showing another example of the contents of the transmission data transmitted from the FAX to the portable information terminal device via the communication server. The message data is transmitted from the FAX to the CS in the following order from to. , CS to PDA. In the figure, the source, destination and message contents of are the same as in FIG. Here, the signal format for transmitting the ID number of the PDA, which is the real destination, from the FAX to the CS is a digital signal instead of the tone signal shown in FIG. In a general fax, when sending a message other than a fax image data signal, there is no other method than using a telephone tone signal, but a fax compatible with the data delivery system of the present invention, a personal computer, a modem, etc.
With a system that creates the image data signal itself of AX, it is possible to communicate between FAX and CS by a digital signal. In this case, FAX to CS
Not only the ID number of the PDA of the destination is sent to
It is also possible to transmit a message indicating the outline content of a FAX image, which will be described later with reference to FIG. 10, and a password required for security together.

FIG. 7 is a diagram showing the contents of the transmission data in FIG. 6 more specifically. The basic source and destination are the same as those in FIGS. 5 and 6, but from the FAX. A process of transmitting a FAX header including a schematic content of the FAX image to the CS and information such as a detailed ID of the sender as a digital signal to the CS and a process of transferring the transmitted FAX header from the CS to the PDA are added. Since it is possible to know the outline content of the FAX from the FAX header sent before instructing the transfer of the FAX image data on the destination PDA, whether the FAX text should be transferred immediately or not. Can be confirmed in advance.

FIG. 8 is a diagram showing an example of the format of a message transmitted from the communication server to the portable information terminal device. In FIG. 5, a message indicating that the CS has received the FAX in FIG. 5 is sent to the destination PDA. It is an example of the message format at the time. FIG. 8A shows F
This is the image data sent by the FAX to the CS, and in a normal FAX, the name of the sender, the telephone number, the date, the time, etc., output by the FAX itself, before the FAX text read by the scanner of the FAX. Information is transmitted as a header image. In FIG. 8B, the CS is the destination PD
Transfer to PDA via pager connected to A F
This is the content of the AX header, which is the FAX received by the CS.
The image pattern of the header is converted into a character code by character recognition and the character code is transmitted. In Fig. 8 (c), the PDA finally sends a fax to the CS.
After making a request to send the image data of
It is FAX image data transmitted to A.

In FIG. 8B, the PDA has once received the character code conversion of the FAX header. However, since character recognition may be incorrect, the FAX image data transmitted from the CS to the PDA includes It is preferable to send the image data of the FAX header and the image data of the FAX text sent by the FAX to the CS. FA
Although the character recognition circuit of the X header will be described later with reference to FIG. 16, it is not necessary to transmit the FAX header as image data if the character recognition is surely performed. For this, the character recognition circuit of CS may calculate the recognition probability, and if it is equal to or less than a certain value, the image data of the FAX header may be transmitted. Since the PDA only receives the FAX image regardless of whether the FAX header is sent or not, it is not necessary to send the above-mentioned determination result of sending the FAX header image from the CS side to the PDA in advance.

FIG. 9 is a diagram showing an example of specific contents of a message transmitted from the communication server to the portable information terminal device. In the figure, CS is the PD
It is a FAX reception message indicating that the FAX addressed to A has been received. Is the ID information such as the name and telephone number of the sender that the sender FAX is sending to the sender FAX, and is one for notifying the sender PDA of the received FAX outline as much as possible. It becomes a means.

It is connected to 12030. For each function,
This is the same as the line I / F in CS shown in FIG.

FIG. 13 is a block diagram showing an example of the functional configuration of the buffering adapter used in the data delivery system of the present invention. The ID number of the destination PDA to which the FAX explained in FIG. 5 transmits as a tone signal. The fax
Instead of waiting for the carrier from CS to manually enter the carrier, the user of CS automatically detects the carrier of CS and sends it to destination P.
1 shows a buffer link adapter for transmitting a DA ID number. As shown in FIG. 5, the sender FAX 130
The signal 13001 originated from 00 is a tone signal (FIG. 5) that first represents the CS telephone number, and then the destination P
The tone signal represents the DA number (FIG. 5) and the digital signal represents the FAX image data (FIG. 5).

The buffering adapter 13010 receives the signal 13001 via the FAX interface 13011, and the FAX signal decomposing circuit 1301 causes the buffer 1330 to receive the CS signal.
Phone number, PDA number, FAX image signal. Then, the telephone number is stored in the TEL number buffer 13013 and then output to the public line 13030 through this, so that the CS can be called. When the CS is busy and the line is not connected, the telephone number is again output from the TEL number buffer 13013 to the public line 13030. After the PDA number is stored in the PDA # buffer 13014, the CS carrier detection circuit 13016 outputs the CS
It will be in a waiting state until the reception carrier transmitted from is detected. When the CS transmits the reception carrier, the CS carrier detection circuit 13016 causes the switch 13017 to turn “O”.

Is output to CS through.

In the above example, the FAX image signal is stored once in the FAX signal buffer 13015. However, in practice, the FAX carrier 13000 does not start until the CS carrier detection circuit 13016 detects the CS carrier signal. Is enough. Normally, FAX
13000 generally does not start transmitting fax images unless it receives fax carrier from CS,
In this case, the fax signal buffer 13015 may be omitted.

FIG. 14 is a flow chart showing the processing and data flow by each device constituting the data delivery system of the present invention, the left side is the operation flow in the FAX of the transmission source, the center is the operation flow in the CS, The right side is the operation flow in the destination PDA. The sender FAX first calls the CS (step 14
000), the CS receives this call (step 1405).
0). Signal direction 14001 is transmitted from FAX to CS. Next, the CS outputs a carrier (step 14060), the carrier 14011 is sent to the FAX, and the FAX receives the CS carrier (step 140).
10). The FAX of the transmission source, which recognizes the completion of the connection with the CS by the CS carrier, transmits the PDA number of the transmission destination (PDA
#) To the CS (step 14020),
The CS receives the PDA # (step 14070). Finally, the FAX transmits a FAX image signal to the CS (step 14030), and the CS receives this FAX image signal (step 14080). The work of the fax is completed (step 14040), but these operations are exactly the same as those of the normal fax except the PDA # transmission. Note that the PDA # transmission operation is performed manually including the telephone number transmission, or automatically using the buffering adapter shown in FIG.

Next, the CS calls the pager connected to the destination PDA (step 14090), and the pager starts reception (step 14150). Then, the CS sends a message indicating the FAX reception and the FA
Send information about X to the pager (step 1
4100), the pager receives the information (step 14160). After that, the pager PDs the received information.
The data is transferred to A (step 14170), and the PDA displays the information as shown in FIG. 10 to allow the user of the PDA to determine whether to transmit the FAX image data (step 14180). If the PDA is instructed to send fax image data, the PDA
Calls the CS using PHS (step 1419
0), the modem provided at the CS answers the call (step 14110). Then, the PDA transmits a FAX image data transmission request signal to the CS (step 14200), the CS receives the transmission request signal (step 14120), and then transmits the FAX image data to the PDA. (Step 14130).
The PDA receives the transmitted FAX image data (step 14210), displays it on the PDA display (step 14220), and ends the series of operations (steps 14140 and 14230).

FIG. 15 is a diagram for explaining the FAX header separation and pattern recognition processing shown in FIG. In the figure, the FAX image 15030 is
A two-dimensional bitmap image (1 bit for each pixel) is stored in the HDD connected to the CS, and is composed of a header portion 15010 and a handwritten character portion 15040. Of these, the handwritten character portion has various sizes, shapes, sharpness, etc., and it is difficult to perform pattern recognition. Therefore, the handwritten character portion is transferred as a bitmap image to the destination PDA. On the other hand, the header part 15010
In general, since the fax is generally transmitted as a digital image from the sender, the character size and shape are constant and the character definition is high. Therefore, it is easy to convert the character code into a character code by pattern recognition. However, since the header portion 15010 and the handwritten character portion 15040 are included in the same bitmap image, it is necessary to separate them. In this embodiment, the header portion 15
The above-described separation is performed by utilizing the fact that the space (blank) portion 15020 is always inserted between the 010 and the handwritten character portion 15040.

FIG. 16 is a block diagram showing an example of a circuit for performing the FAX header separation and pattern recognition processing shown in FIG. In the same figure, the FAX image data sent from the public line 16000 is the FAX receiving circuit 1
After being converted into digital image data through 6010, the image data is stored in the FAX image buffer 16020, and then by the FAX image classification device 16030.
The space portion described with reference to FIG. 15 is detected from this image data, and the header portion and the handwritten character portion are separated. Of these, the header section is the FAX header section image buffer 160.
40, the bit map information is decomposed into bit map information for each character by a character pattern recognition circuit 16060, and then converted into a character code by a character code conversion circuit 16070, and a public line is transmitted through a FAX modem 16090. 16100 and the destination P is sent according to the format shown in FIG.
Transferred to DA. On the other hand, the handwritten character portion is stored in the FAX handwritten portion image buffer 16050, and the P
When a request for transmitting a FAX image is received from the DA, the FAX image is read from the FAX handwriting image buffer 16050, transmitted to the public line 16100 through the FAX modem 16090, and transferred to the PDA.

FIG. 17 is a flow chart showing an example of compression and decompression processing of image data in the data delivery system of the present invention. By utilizing the fact that FAX image data is once stored in CS, FAX run length is used. A processing operation for improving the data compression efficiency as compared with the format and transferring the data to the PDA in a short time will be shown.
In the figure, the FAX run length + Huffman coded data 17000 received by the CS has only a one-line buffer for printing one line immediately after the FAX transfers one line, Can store the entire screen of the FAX image in the memory at the same time. Here, the compression processing is further performed on the data transmitted in one dimension (step 17010) and the compressed data 17
020 is created, and the HDD in CS remains compressed
To the destination PDA (step 17030). Compressed data 17020 is the original FAX
Since it is further compressed compared to run length + Huffman coded data 17000, the transfer time is shorter, and it is also possible to perform the handshake necessary for digital data transfer and the retransmission processing when an error occurs. As a result, FAX data can be transferred more reliably. The destination PDA that receives the compressed data 17020 performs the corresponding decoding process (step 170).

FIG. 18 is a flow chart showing another example of image data compression and decompression processing in the data delivery system of the present invention. As in the case of FIG.
The processing operation for improving the data compression efficiency as compared with the FAX run length format by utilizing the fact that the image data of AX is once stored in the CS and transferring it to the PDA in a short time will be shown. FAX received by CS in the figure
The run length + Huffman encoded data 18000 is F
While the AX has only one line buffer for transferring one line at a time and printing the one line immediately, the CS can simultaneously store the entire screen of the FAX image in the memory. Here, the data sent in one dimension is once expanded into bitmap data (step 1
8010) A compression process (for example, block coding + Huffman coding) in which the compression efficiency is further increased by taking the correlation in the two-dimensional direction is performed (step 18020), and compressed data 18030 is created. Then, the compressed data 180
30 is accumulated and stored in the CS HDD, and the transfer process to the destination PDA is performed (step 18040). Thereafter, the PDA receives the transfer of the compressed data as in the case of FIG. 17, and performs the decoding process (step 18050) to reconstruct the bitmap image data 18060,
Display on the display on A (step 1807)

Both FIG. 17 and FIG. 18 utilize the fact that the CS can store the entire data at the same time in addition to the compression by the one-dimensional run length + Huffman coding which is the original compression method in the general FAX. This is an example of performing highly efficient compression processing. Particularly, in the compression processing shown in FIG. 18, since the correlation in the two-dimensional direction of the original bitmap image can be used, a highly efficient compression rate can be obtained. it can.

FIG. 19 is a block diagram showing the overall configuration of an embodiment in which the data source in the data delivery system of the present invention is a portable information terminal device.
The sender of the image data is not a fax but another PD
The case of A is shown. In the figure, CS1 receiving a FAX
Since the configurations of 9040 and the PDA 19100 of the transmission destination are exactly the same as those in FIG. 1, the description thereof is omitted here.
In this embodiment, the sender of FAX image data is PDA.
It is characterized by being 19000. That is, P
The FAX image data transmitted from the DA 19000 is transmitted to the general public line 19020 via the FAX interface 19001 and transferred to the CS. Here, from the source PDA 19000 to the destination PDA 19
Assuming that the FAX is directly transmitted to the 100, if the FAX cannot be received for some reason such as when the PDA 19100 is moving, the PDA 19000 of the transmission source repeatedly transmits the FAX. Need to resend. Many normal faxes are equipped with a resend function as standard equipment, but if the sender is a PDA, it is necessary to access the general public line 19020 by a method such as wireless communication every time resending is performed. At that time, since a large amount of power is consumed, the PDA 19000 of the transmission source wastes its operable time each time it is retransmitted.
Therefore, by interposing CS as in the present embodiment, the source PDA 19000 can transmit a FAX to another PDA 19100 without being influenced by the state of the destination. However, even in this case, CS190
40 itself may be busy, in which case C
The solution can be achieved by providing a plurality of telephone lines between S19040 and the general public line.

FIG. 20 is a block diagram showing the overall configuration of an embodiment in which the image data of FAX transmitted to the portable information terminal device in the data delivery system of the present invention can be transferred to another portable information terminal device or FAX. Is. In the figure, the sender FAX # 1 (2000) is the destination PDA # 1.
CS2011 to send FAX to (20010)
Send FAX image data to 0. In response to this, the CS20110 sends a message indicating the FAX reception via the mobile phone 20030 or the like to the destination PDA #.
1 (20010). PDA # 1 (2001
The user of 0) confirms the outline of the FAX shown in FIG. 10 and the FAX image data received by himself / herself, and then determines whether or not the FAX needs to be transferred to another PDA or the like. For example, if it is determined that the user of PDA # 2 (20120) needs to show the FAX, CS201
The FAX image data stored and stored in the PDA 10 or a message indicating the FAX reception similar to that received by the destination PDA # 1 (20010) is displayed on the PDA.
CS2 to send to # 2 (20120)
A request instruction is sent to 110.

As described above, the PDA # 1 (20010) does not need to transmit a large amount of FAX image data again, and power consumption can be saved. In particular, when it is necessary to carry out broadcast communication to a plurality of PDAs and FAXes, all of the transmissions should be made on behalf of CS20110, which is normally powered and can make a wired call, instead of PDA # 1 (20010). It is possible to save power consumption very effectively. Also, F
The AX data capacity is too large and the PDA # 1 (2
0010) cannot be received, or when the resolution of the PDA display is inferior to that of the FAX as will be described later with reference to FIG. 21, all the FAX image data cannot be confirmed on the PDA display. The user of the destination PDA # 1 (20010) transfers the image data of the FAX transmitted to the FAX # 2 (20020) installed nearest to the C #.
The request instruction can be sent to S20110.

FIG. 21 is a view (No. 1) for explaining an example of the measures taken when the data delivery system of the present invention is restricted by the performance of the portable information terminal device.
A method of coping with a case where it is meaningless to transfer all image data to the PDA because the resolution of the display of the PDA of the transmission destination is lower than the resolution of the FAX of the transmission source will be described.

FIG. 21A shows a message displayed by the PDA after the CS receives the FAX and then sends a message indicating the FAX reception to the destination PDA. Since the message in the figure is basically the same as that in FIG. 10, the overall description will be omitted, but only the message 21050 is different, and not the entire fax image data but the fax overview image transfer. It is a message to encourage.

FIG. 21B shows an example of a case where the destination PDA receives the FAX outline image and displays it on the disc play. In the figure, a fax outline image 21090 is displayed on the display 21080 of the destination PDA.
An icon group 21100 for scrolling the outline image 21090 up and down, and an icon group for giving various commands to the PDA are displayed. Generally FAX
Since the vertical length of the FAX is unlimited, the FAX outline image 210 can be displayed by using the scroll icon 21100.
90 can be scrolled up and down.

As an outline image of FAX, for example,
A method in which the number of pixels is reduced to 1 / n × n by representing one of vertical and horizontal n × n pixels, or black is produced when the average value of n × n pixels exceeds a certain threshold value. Various pixel reduction methods such as a method are used to transfer the outline information in which the total number of pixels of the FAX is reduced to the PDA for display. Therefore, since it is difficult to read fine characters with the outline image as it is, all the data before the number of pixels is reduced must be transferred if necessary. Icon 21
110 is for the user to instruct this, and if the full-text transfer is to be performed immediately on the spot, “No” is displayed.
w ”later or if no full-text transfer is performed“ Aft
"er" icon.

Next, the destination of the full-text transfer is specified.
The resolution of the display provided in the DA is generally FA
Since the resolution is lower than that of X, it is considered appropriate to transfer to another FAX installed near the user, as described in FIG. In this case, F at 21120
Before instructing the transfer to AX, the FA near by 21130
Enter the phone number of X or FA of 21140
Select from the X phone number list and specify the FAX to which you want to transfer. Further, when transferring to another PDA as described in FIG. 20, a transfer command is instructed at 21150. Then, the destination can be selected and transferred from the PDA list of 21160. Phone number list 2
1140 and PDA list 21160 indicate the PDA
It is linked to a database such as an address book owned by and can be referred to as a relational database. As described above, by first transferring the summary image to the FAX to the destination PDA, only the minimum amount of information that can be displayed by the PDA is transferred, so that the transfer time can be saved. it can.

FIG. 22 is a diagram (No. 2) for explaining an example of the countermeasure when the data delivery system of the present invention is restricted by the performance of the portable information terminal device.
As shown in FIG. 21, after the outline image of the FAX is transferred to the PDA of the transmission destination, the FAX image data is transferred as it is. As previously mentioned,
Since the display of the PDA does not have the resolution of FAX, it is difficult to display it even if the entire text of FAX image data is transferred. However, as a result of referring to the FAX outline image transferred first, if there is a portion to be referred to for details, it is relatively easy to zoom in and display only that portion.

In order to realize such processing, the whole sentence of the FAX image data may be transferred and then zoomed up. However, in this embodiment, the FAX outline image 2201 is displayed.
From 0, a part is selected as the zoom area 22020 and only that part is transferred to save transfer time. In FIG. 22, the destination PDA uses a touch panel display in which a touch panel is combined with a display such as a liquid crystal display, and a pen 22030 is used to specify an area to be zoomed up on the FAX outline image 22010 displayed on the display. Therefore, the zoom area 22020 is defined. Then, by instructing the transfer with the icon 22040, all the FAX image data included in the zoom area designated by the CS is transferred. The transferred fax image is a PDA
However, the enlargement ratio depends on the definition of the zoom area, and all image data is always displayed in the scroll window, or the zoom area is displayed on the full screen of the PDA based on the algorithm described in FIG. It is also possible to automatically perform scaling so that it can be displayed.

FIG. 23 is a diagram for explaining a process of automatically deleting and transferring an unnecessary portion in FAX image data in the data delivery system of the present invention. FIG. 23A shows FAX image data 23000 sent from the FAX that is the transmission source, and there are horizontal blank areas (23010, 23020) between the header and the handwritten character portion and also in the handwritten character portion. include. FIG. 23
(B) is a FAX image 23030 in which this blank portion is deleted and transferred, and the FAX image 23030 described with reference to FIG.
A blank portion in a horizontal row is detected by the same method as in the X image classification device, and this blank portion is deleted. In this case, if you delete all the blank lines here, the header and handwritten character part,
Characters above and below the handwritten character are too close to each other, making it difficult to read, so delete only a certain number of blank lines.

Although an example in which a blank is detected is given here, in addition to this, by detecting the connection of the lines forming the FAX handwritten image and shortening the length of the line, the entire size is reduced. It is also possible to reduce the size. This is effective, for example, when sending a block diagram as shown in FIG. 22, but when sending something like a mechanical drawing, the scale such as the aspect ratio becomes incorrect. Therefore, this can be solved by preparing a command for the FAX sender or PDA user to cancel this function and instructing this. In particular, when the sender gives an instruction for this command, it is possible to mix the instruction with a digital signal such as the PDA number shown in FIG. 6 and send it to the CS, while the user of the PDA gives an instruction. In this case, when the transfer instruction is sent to the CS by the PHS, the command instruction can be mixed in the transfer instruction to give the instruction to the CS.

[0061]

As described in detail above, according to the data delivery system of the present invention, when the image data of FAX is used as the transmission data, the sender first sends the FAX to the communication server. In doing so, the ID number that identifies the portable information terminal device of the recipient is transmitted together with the telephone number of the communication server. The communication server stores the received FAX image data in a large-capacity storage medium, and then sends the FAX to the pager connected to the recipient's portable information terminal device.
Send a message that X has arrived. At this time, the message contains the outline of the received FAX. The recipient can know the arrival of the fax by referring to the message received by the pager, and at the same time, the recipient can confirm the outline content immediately on the spot.

Then, depending on the importance of the contents sent by FAX, and when the mobile phone attached to the portable information terminal device becomes ready for use, the recipient can carry the portable information terminal device. A transfer request for the image data is sent to the communication server via the telephone, and the whole or a part of the image data stored in the storage medium of the communication server is transferred to the portable information terminal device of the receiver and displayed. The effect that it can be obtained is obtained. Further, if necessary, the receiver instructs the communication server from the portable information terminal device to transfer the image data stored in the storage medium of the communication server to another portable information terminal device or a receiver of FAX. The effect that it can be transferred is also obtained.
