【００２２】
受信文書のメール送信処理として、まずメモリユニット１０２に最後に送信したネットワークファクシミリのアドレスが登録されているかどうかチェックする（Ｓ２０１）。未登録の場合（Ｓ２０１の「Ｎ」）は始めての送信であるため、送信アドレステーブルの先頭のアドレスを送信アドレスとして読み出す（Ｓ２０２）が、登録されている場合（Ｓ２０１の「Ｙ」）はそのアドレスを読み出し、アドレステーブル内のどの位置にあるかを検索する（Ｓ２０３）。検索の結果見つかった場合（Ｓ２０４の「Ｙ」）において、テーブルエンドでないとき（Ｓ２０５の「Ｎ」）は次のアドレスを読み出し送信アドレスとし（Ｓ２０６）、テーブルエンドであるとき（Ｓ２０５の「Ｙ」）はテーブル先頭アドレスを送信アドレスとして読み出す（Ｓ２０２）。
【００２３】
なお、テーブルが見つからない場合は、アドレスがテーブルから削除されているので先頭のアドレスを送信アドレスとして読み出す。
【００２４】
読み出されたアドレスに対して、図３に示したと同様に電子メールに文書を添付して送信する（Ｓ２０７）。送信後、送信を行ったアドレスを、最後に送信したアドレスとしてメモリユニット１０２に保存（登録）する。
【００２５】
以上のようにして送信宛先が循環的に処理され、結果としてネットワークファクシミリを分散処理させ高速に出力することができる。なお、図４では最後に送信したアドレスを保存し、ラウンドロビンを実現しているが、アドレステーブル内のポインタを保存する方法でも良い。
【００２６】
図５は送信アドレス決定処理のフローチャートを示し、図６に電子メール送信フローチャートを示し、表２に送信アドレステーブルを示す。なお、この場合にも公衆網２００からの受信処理とメモリユニット１０２への文書蓄積は図３で説明した同様である。
【００２７】
【表２】

【００２８】
電子メールの送信処理は次通りである。すなわち、図５に示すように、まず送信ファイル情報をメモリユニットから読み出し、新規送信なのか分割処理した後の継続送信なのかを判断する（Ｓ３０１）。新規送信の場合（Ｓ３０１の「Ｙ」）は、ラウンドロビン処理における次送信宛先検索のため、メモリユニット１０２に最後に送信したネットワークファクシミリのアドレスが登録されているかどうかチェックする（Ｓ３０４）。登録されている場合（Ｓ３０４の「Ｙ」）はそのアドレスを読み出し、アドレステーブル内のどの位置にあるかを検索する（Ｓ３０５）。検索の結果見つかった場合（Ｓ３０６の「Ｙ」）において、テーブルエンドでないとき（Ｓ３０７の「Ｎ」）は次のアドレスを読み出し送信アドレスとし（Ｓ３０９）、テーブルエンドであるとき（Ｓ３０７の「Ｙ」）はテーブル先頭アドレスを送信アドレスとして読み出す（Ｓ３０８）。Ｓ３０４において未登録の場合（Ｓ３０４の「Ｎ」）は始めての送信であるため、送信アドレステーブルの先頭のアドレスを送信アドレスとして読み出す（Ｓ３０８）。
【００２９】
ただし、Ｓ３０８およびＳ３０９において、アドレスを読み出した場合においては、アドレスが使用中か否かを判断する（Ｓ３１０）。読み出されたアドレスのステイタスが使用中の場合には（Ｓ３１０の「Ｙ」）、新規送信の宛先として割り当てることはできないためそれ次アドレスを確認し（Ｓ３１１）、未使用のアドレスの場合（Ｓ３１０の「Ｎ」）にはそのアドレスを送信宛先として決定する（Ｓ３１２）。
【００３０】
一方、Ｓ３０１において継続送信の場合には（Ｓ３０１の「Ｎ」）、送信ファイル情報のファイルナンバからどの宛先へ送信するのか、アドレステーブルを検索し（Ｓ３０２）、アドレスを読み出し（Ｓ３０３）、検索の結果見つかったアドレスを送信アドレスとして決定する（Ｓ３１２）。
【００３１】
次に、図６に示すように、送信ファイル情報を読み出し（Ｓ４０１）、送信アドレス決定処理後（Ｓ４０２）、未送信データサイズと送信先ネットワークファクシミリの受信可能サイズを比較し、分割送信する必要があるかどうか判断する（Ｓ４０３）。分割が必要ない場合（Ｓ４０３の「Ｎ」）は、全て電子メールに添付して送信する（Ｓ４０７）。分割が必要な場合（Ｓ４０３の「Ｙ」）は、送信可能なページまで送信を行う（Ｓ４０４）。分割送信により未送信ページが存在する場合は、そのままアドレステーブルにおけるネットワークファクシミリのステイタスを使用中とし（Ｓ４０５）、ウェイトをかけ（Ｓ４０６）、一定時間後再び送信処理を行う（Ｓ４０１）。全てのページが送信完了し（Ｓ４０７）、送信アドレスが使用中でないとき（Ｓ４０７）は、使用中のアドレスを未使用にセットし（Ｓ４０８，Ｓ４０９）送信処理を終了させる。

表４，表５，図８では、受信文書を、等倍出力が可能なネットワークファクシミリに送信する場合を説明する。公衆網からの受信処理とメモリユニットへの文書蓄積は上述したと同様である。
【００３９】
図８に示すように、公衆網２００から受信した文書についての情報を読み出し、受信能力テーブルで変倍しなくて良い宛先が存在するかどうか検索を行う（Ｓ５０１）。宛先が存在した場合は（Ｓ５０２の「Ｙ」）、そのアドレスをアドレステーブルから読み出す（Ｓ５０５）。更に線密度や圧縮モードなどを変換する必要かあるかどうかなどをチェックし（Ｓ５０６）、そのまま受信できない場合（Ｓ５０６の「Ｙ」）は線密度、圧縮モード変換して（Ｓ５０７）、メール送信する（Ｓ５０８）。宛先が存在しなかった場合は、あらかじめ設定されたテーブル内のアドレスを読み出し（Ｓ５０２の「Ｎ」）、画像変換ユニットにそのアドレス端末の能力と画像を通知し画像変倍を行い（Ｓ５０３）、必要に応じてさらに線密度や圧縮モードを変換する（Ｓ５０５，Ｓ５０７）。そして変換された画像を決定した送信アドレスに対してメール送信を行う（Ｓ５０８）。なお、図８では、等倍で出力させる例を記したが、同様になるべく線密度を変換しないで出力させる場合や、さらになるべく等倍かつ等線密度で出力させるようにしてもよい。
【００４０】
以下に、ネットワーク端末の能力をグループ化して受信端末能力テーブルに登録しておく場合を説明する。

【００４３】
【表７】

【００４４】
図９では、メール送信処理ではまず送信文書の文書幅を読み出し（Ｓ６０１）、最終送信アドレステーブルからその原稿幅に対応するアドレスが登録されているかどうかチェックする（Ｓ６０２）。登録されていない場合（Ｓ６０２の「Ｎ」）は、始めての送信なので該当幅の先頭アドレスを送信アドレスとして決定する（Ｓ６０６）が、登録されている場合はアドレスを該当するテーブル内で検索し（Ｓ６０３）、発見された場合（Ｓ６０６の「Ｙ」）においてテーブルエンドでないときは次のテーブルを送信アドレスとして決定する（Ｓ６０７）。そして、決定されたネットワークファクシミリへの送信において線密度や圧縮モードの変換が必要な場合（Ｓ６０８の「Ｙ」）は、画像変換を行い（Ｓ６０９）、電子メールに添付して送信を行い（Ｓ６１０）、送信後、送信アドレスを該当する最終送信アドレステーブルに登録を行う（Ｓ６１１）。Ｓ６０８において、圧縮モードの変換が必要でない場合にも、電子メールに添付して送信を行い（Ｓ６１０）、送信後、送信アドレスを該当する最終送信アドレステーブルに登録を行う（Ｓ６１１）。
【００４５】
本実施形態では、でき得る限り、等倍出力を行いかつラウンドロビン方式による出力が可能となる。
【００４６】
なお、本実施形態では等倍で出力しラウンドロビンさせる例を記したが、同様にでき得る限り線密度を変換せずラウンドロビン出力させる場合や、さらにでき得る限り等倍かつ等線密度でラウンドロビンさせることもできる。また、最後に送信したアドレスを保存しラウンドロビンを実現させていたが、アドレステーブル内のポインタを保存する方法による送信も可能である。

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram according to an embodiment of a communication apparatus of the present invention. In FIG. 1, a communication device 1 includes a system control unit 101 that controls the functions of the entire device, a system control program ROM, a work RAM, a received image storage RAM (or a large-capacity storage device such as a magnetic storage device). ), A memory unit 102 including a power-backed RAM for storing system setting information and network facsimile address information, and a user I / F unit 103 having various keys and displays necessary for setting and the like and for inputting and outputting data. And the public network I / F unit 104 that controls facsimile transmission / reception via the public network 200 (see FIG. 2A) and the network (LAN or WAN) 100 (see FIG. 2B). A network that converts documents (images) of facsimile data into images that can be attached to e-mails And click I / F unit 105, and compression and expansion of the received document and an image conversion unit 106 which performs encoding / decoding of TIFF performs scaling and linear density conversion.
[0018]
FIG. 2A shows a system in which the communication apparatus 1 of FIG. 1 is connected to a network facsimile apparatus (“network terminal” of the present invention) netfax_ 1 via the network 100 and connected to the public network 200. 2B, the communication apparatus 1 of FIG. 1 is connected to a network facsimile apparatus (“network terminal” of the present invention) netfax_1, netfax_2,..., Netfax_n via a network (LAN or WAN) 100. A system connected to the public network 200 is shown. 2A and 2B, a facsimile machine (represented by reference numeral 3) is connected to the public network 200. Further, although the network terminal described above uses a terminal capable of receiving by SMTP, a network facsimile that can receive mail only by POP3 can be configured in combination with a mail server.
[0019]
The operation of the communication apparatus 1 in the system of FIG. 2A will be described with reference to the flowchart of FIG. In the system of FIG. 2A, the communication device 1 receives facsimile data from the facsimile device 3 of the public network 200 via the public network I / F unit 104 (S101). All documents related to the received facsimile data are temporarily stored in the memory unit 102. Next, the transmission address (host name or IP address and mail address) of the network facsimile registered in the memory unit 102 is read (S102). Subsequently, the received document stored in the memory unit 102 is read out, coded in TIFF by the image conversion unit 106, and then transferred to the network I / F unit 105 together with the network facsimile address information. The network I / F unit 105 converts the document so that it can be attached to an e-mail, and performs SMTP transmission to the notified address (S103). If the address is a host name, the DNS is inquired about the IP address, and the SMTP connection is made to the notified IP address and transmitted. As a result, the network facsimile performs SMTP reception processing and outputs the received document from the plotter.
[0020]
The operation of the communication apparatus 1 in the system of FIG. 2B will be described with reference to the flowchart of FIG. Table 1 shows a transmission address table. 2B, reception processing from the public network 200 and document storage in the memory unit are the same as those in FIG.
[0021]
[Table 1]

[0022]
As a mail transmission process for a received document, first, it is checked whether or not the address of the network facsimile transmitted last is registered in the memory unit 102 (S201). If it is not registered (“N” in S201) is the first transmission, the first address in the transmission address table is read as a transmission address (S202), but if it is registered (“Y” in S201) The address is read out and the position in the address table is searched (S203). When it is found as a result of the search (“Y” in S204), when it is not the table end (“N” in S205), the next address is used as the read transmission address (S206), and when it is the table end (“Y” in S205). ) Reads the table head address as the transmission address (S202).
[0023]
If the table is not found, the address is deleted from the table, so the head address is read as the transmission address.
[0024]
A document is attached to the e-mail and transmitted to the read address in the same manner as shown in FIG. 3 (S207). After transmission, the transmitted address is stored (registered) in the memory unit 102 as the last transmitted address.
[0025]
As described above, the transmission destination is cyclically processed, and as a result, the network facsimile can be distributed and output at high speed. In FIG. 4, the last transmitted address is stored to realize round robin, but a method of storing a pointer in the address table may be used.
[0026]
FIG. 5 shows a flowchart of the transmission address determination process, FIG. 6 shows an e-mail transmission flowchart, and Table 2 shows a transmission address table. In this case, the reception process from the public network 200 and the document storage in the memory unit 102 are the same as described with reference to FIG.
[0027]
[Table 2]

[0028]
The e-mail transmission process is as follows. That is, as shown in FIG. 5, first, the transmission file information is read from the memory unit, and it is determined whether the transmission is new transmission or continuous transmission after division processing (S301). In the case of new transmission (“Y” in S301), it is checked whether the address of the network facsimile transmitted last is registered in the memory unit 102 for the next transmission destination search in the round robin processing (S304). If registered (“Y” in S304), the address is read out, and the position in the address table is searched (S305). When it is found as a result of the search (“Y” in S306), when it is not the table end (“N” in S307), the next address is the read transmission address (S309), and when it is the table end (“Y” in S307). ) Reads out the table head address as the transmission address (S308). If it is not registered in S304 ("N" in S304), it is the first transmission, so the top address of the transmission address table is read as the transmission address (S308).
[0029]
However, if the address is read in S308 and S309, it is determined whether the address is in use (S310). If the status of the read address is in use (“Y” in S310), it cannot be assigned as a new transmission destination, so the next address is confirmed (S311), and if it is an unused address (S310). "N") is determined as the transmission destination (S312).
[0030]
On the other hand, in the case of continuous transmission in S301 ("N" in S301), the address table is searched to determine which destination is transmitted from the file number of the transmission file information (S302), the address is read (S303), The address found as a result is determined as a transmission address (S312).
[0031]
Next, as shown in FIG. 6, the transmission file information is read (S401), and after the transmission address determination process (S402), it is necessary to compare the untransmitted data size with the receivable size of the destination network facsimile and perform divided transmission. It is determined whether or not there is (S403). When division is not necessary (“N” in S403), all are attached to the e-mail and transmitted (S407). When division is necessary (“Y” in S403), transmission is performed up to a transmittable page (S404). If there is an untransmitted page due to divided transmission, the status of the network facsimile in the address table is used as it is (S405), a wait is applied (S406), and transmission processing is performed again after a fixed time (S401). When all the pages have been transmitted (S407) and the transmission address is not in use (S407), the used address is set to unused (S408, S409), and the transmission process is terminated.
[0032]
Table 3 shows examples of network terminal capability settings (write width, compression mode, and linear density).
[0033]
[Table 3]

[0034]
FIG. 7 shows a reception protocol from the public network. Here, the mail reception capability of the network facsimile used as the output terminal is input from the user I / F unit in advance and stored in the memory unit. When an incoming call is received from the public network (CNG), processing is performed using the normal facsimile protocol. However, in the capacity declaration (DIS) at the time of reception, a declaration is made in accordance with the capacity of the network facsimile registered in the memory unit. And receive the original. Also in this case, the transmission processing to the network facsimile is performed in the same manner as shown in FIG.
[0035]
The case where the reception capability is registered will be described below. Table 4 shows an address table, Table 5 shows a receiving terminal capability table, and FIG. 8 shows a flowchart of e-mail transmission.
[0036]
[Table 4]

[0037]
[Table 5]

[0038]
Table 4, Table 5, and FIG. 8 explain the case where the received document is transmitted to a network facsimile capable of the same size output. The reception processing from the public network and the document storage in the memory unit are the same as described above.
[0039]
As shown in FIG. 8, information about a document received from the public network 200 is read, and a search is performed as to whether there is a destination that does not need to be scaled in the reception capability table (S501). If the destination exists (“Y” in S502), the address is read from the address table (S505). Further, it is checked whether or not it is necessary to convert the line density, the compression mode, etc. (S506). If it cannot be received as it is ("Y" in S506), the line density and the compression mode are converted (S507) and sent by e-mail. (S508). If the destination does not exist, the address in the preset table is read (“N” in S502), the image conversion unit is notified of the capability and image of the address terminal, and image scaling is performed (S503). If necessary, the linear density and compression mode are further converted (S505, S507). Then, mail transmission is performed to the transmission address for which the converted image has been determined (S508). In FIG. 8, an example in which output is performed at the same magnification has been described. However, the output may be performed without converting the linear density as much as possible, or may be output at the same linear density as possible.
[0040]
A case will be described below in which network terminal capabilities are grouped and registered in the receiving terminal capability table.
[0041]
Table 5 is used as the receiving terminal capability table. Table 6 shows an address table, Table 7 shows a final transmission address table, and FIG. 9 shows a flowchart of electronic mail transmission. Here, an example of round robin in recording width units is shown. The reception processing from the public network 200 and the memory unit are the same as in the above-described embodiment.
[0042]
[Table 6]

[0043]
[Table 7]

[0044]
In FIG. 9, in the mail transmission process, the document width of the transmission document is first read (S601), and it is checked whether an address corresponding to the document width is registered from the final transmission address table (S602). If it is not registered ("N" in S602), since it is the first transmission, the leading address of the corresponding width is determined as the transmission address (S606). If registered, the address is searched in the corresponding table ( In S603), if it is found ("Y" in S606) and it is not the table end, the next table is determined as the transmission address (S607). If the conversion to the line density or compression mode is necessary for transmission to the determined network facsimile (“Y” in S608), image conversion is performed (S609), and transmission is performed by attaching to the e-mail (S610). ) After transmission, the transmission address is registered in the corresponding final transmission address table (S611). Even if it is not necessary to convert the compression mode in S608, transmission is performed by attaching to the e-mail (S610), and after transmission, the transmission address is registered in the corresponding final transmission address table (S611).
[0045]
In this embodiment, as much as possible, the same-magnification output is performed and the output by the round robin method is possible.
[0046]
In this embodiment, an example in which output is performed at the same magnification and round robin is described. However, in the same way, in the case of performing round robin output without converting the linear density as much as possible, the round is performed at the same magnification and equal linear density as much as possible. It can be made robin. In addition, although the last transmitted address is stored to realize round robin, transmission by a method of storing a pointer in the address table is also possible.
[0047]
【The invention's effect】
In the present invention, by registering the capabilities of each network terminal in advance, when receiving from a facsimile apparatus connected to a public network, facsimile data corresponding to the network terminal is received, thereby providing an advanced image conversion function. Can be eliminated.
[0048]
Furthermore, according to the present invention, the received document can be transmitted by selecting a network terminal that can print out the document as it is without converting the image of the document, so that a desired printout can be obtained. In addition, network terminals can be managed in groups by capability, and print output can be performed in a round-robin manner on a group basis.
