2. Description of the Related Art In recent years, with the spread of computer networks and their terminal devices, electronic mails using networks such as the Internet have been widely used as communication means. Further, even communication devices such as a facsimile device that have conventionally been communicating using a public line have come to have a function of performing communication using electronic mail via the Internet. In such e-mail communication, various functions have become available as technology advances, but some devices do not support new functions.
Further, generally, the function of the receiving side device cannot be recognized from the transmitting side device.

Therefore, although the minimum function defined by the standard called minimum set is normally used for transmission, even if the receiving side device is compatible with the advanced function, its performance is improved. There was a problem that it could not be fully exerted. Also, the sender knows that the device on the receiving side supports other functions, and if he / she wants to use that function, he responded by changing the settings individually. There is also a problem that such an operation is extremely complicated and burdens the user. Such a problem occurs not only in terms of function but also in various points such as language and data format.

As a technique related to the solution of such a problem, Japanese Patent Laid-Open No. 2000-250830 discloses that an electronic mail destination and signature data are stored in association with each other.
There is disclosed an electronic mail creating apparatus that adds a signature based on corresponding signature data to a body when creating an electronic mail to the destination. As shown in this publication, it is common practice to store the destination of electronic mail in an address book or the like in advance, but in this device, the destination and signature data should be stored in association with each other. This makes it possible to create an e-mail with an appropriate signature according to the destination, without the user having to make individual settings.

[0005]

However, in the above publication, only the signature data is described, and the problem still remains in that the function of the receiving side device is fully utilized. The present invention solves such a problem and enables a communication device to transmit an e-mail by making full use of the function of the device on the receiving side, without the user having to make individual settings at the time of transmission. The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. First, an electronic mail device which is an embodiment of a communication device of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the electronic mail device. This e-mail device is a CPU
1, ROM2, RAM3, hard disk drive (H
DD) 4, an operation unit 5, a display unit 6, and a network interface (I / F) 7, which are connected by a system bus 8.

The CPU 1 is a control unit for controlling the entire electronic mail apparatus, and executes various control programs and application programs stored in the ROM 2 and HDD 4 to control the apparatus, edit data, and send information such as destination information. Perform operations such as management. The ROM 2 is a storage means that mainly stores the control program of the apparatus, and the RAM 3 is the CPU 1.
It is a storage unit used for the work memory and the temporary storage of data. The HDD 4 is a storage unit that stores various application programs and data, and also stores an address book for managing destination information and contents of received electronic mail.

The operation unit 5 is composed of a keyboard, a mouse, and the like, and the user directly operates the electronic mail apparatus with these. A liquid crystal display device or a cathode ray tube (CRT) display device can be used as the display unit 6, and an operation screen, which is an interface to the user of the application program, is displayed on this screen to accept operations and instructions, and as a result thereof. Is also displayed. The network I / F 7 is an interface for connecting the electronic mail device to the network.

This e-mail device is a device that sends and receives e-mail with other devices connected to a network such as the Internet via a mail server or directly. Then, a known personal computer (P
It can also be realized by installing and executing a required application program in C).
A general communication operation by this electronic mail device may be the same as that of the conventional one, and therefore its explanation is omitted.

Next, the management of the destination information and the operation of sending an electronic mail using the information, which are the features of the present invention, will be described. This electronic mail apparatus has a table, which stores address information including address and destination information, as an address book in the HDD 4, and the CPU 1 holds and manages the table. The CPU 1 and this address book are the destination management means. Then, when the user selects from the address book the person to whom the e-mail is to be sent and issues a sending instruction, the CPU 1 functions as a mail sending means and performs an e-mail sending operation via the network I / F 7. .

Here, in this electronic mail device,
In the address book, in addition to the recipient's address and destination as shown in Table 1, corresponding to this, as the recipient information, the maximum size of the e-mail that can be received by the recipient, whether split reception is possible, and receipt confirmation It also stores information about the availability, the language used by the recipient, the character encoding method supported by the recipient, and the expression format of the attached file name. These pieces of information may be manually input by the user, or may be automatically input by communicating with the other party's device to obtain the information.

[0017]

[Table 1]

When the CPU 1 tries to send an electronic mail to the destination selected from this address book, the CPU 1 refers to the destination information corresponding to the destination and performs the optimum transmission in light of the situation of the destination. , Do some processing.
Of this processing, first, a portion related to size management will be described with reference to FIG. FIG. 2 is a functional block diagram of the electronic mail device for explaining this processing.

If the data included in the electronic mail is only a text character string, the size does not increase so much, but it is common to send an electronic mail with image data and voice data attached to the electronic mail. This is done in many cases, and in such a case, the size is often huge. On the other hand, the size of the receivable e-mail is limited due to the resource limitation of the e-mail server. Therefore, in this e-mail device, the maximum size of the e-mail that can be received by the other party is stored in the address book, and if the size of the e-mail to be sent is larger than this, it will not be sent. There is.

That is, when an instruction from the user is received,
Although the transmission instruction unit 101 of the CPU 1 shown in FIG. 2 gives an instruction to transmit an electronic mail, when the destination is selected from the address book, the maximum size acquisition unit 102 causes the HDD 4 to operate.
Information on the maximum size of the electronic mail that can be received by the other party is read from the address book stored in the address book storage unit 41. On the other hand, the email to be sent is the sending instruction unit 1
01 to the transmission execution determination unit 10 via the transmission stop determination unit 103
Sent to 4. Here, when the maximum size of the electronic mail to be transmitted is larger than the maximum size acquired by the acquisition unit 102, the transmission stop determination unit 103 determines to stop the transmission and sends the data of the mail to the transmission execution unit 104. Try not to. The transmission execution unit 104 drives the network I / F 7 based on the transmitted data to cause the electronic mail to be transmitted. However, if the transmission is stopped by the transmission stop determination unit 103, the data is transmitted. Since it does not come, it will not be sent. In this case, a warning message to that effect may be displayed on the display unit 6.

For example, if an attempt is made to send a 2-megabyte e-mail with image data attached to Inoue and Sasaki shown in Table 1, Sasaki has a receivable size of 3 megabytes and can send, but Inoue receives Since the possible size is 1 megabyte, it cannot be sent because the size of the email is larger than this. Therefore, the message is sent only to Sasaki and the process ends. By doing so, it is possible to prevent the other party from mistakenly transmitting a large-sized electronic mail that cannot be received, and prevent useless processing and generation of traffic.

There are some known methods for dividing a large-sized electronic mail so as to satisfy the size limitation and transmitting / receiving the divided data. As standard, IETF (In
Known is the one defined in Section 5.2.2 of RFC (Request For Comments) 2046 document issued by ternet Engineering Task Force (Organization), which is an organization that summarizes technical contents related to the Internet. Many e-mail devices (or e-mail applications) do not support such divided transmission / reception, but the destination device supports divided reception by referring to the possibility of divided reception stored in the address book. In this case, this function may be used to perform divided transmission.

In this case, if an attempt is made to send a 2-megabyte e-mail with image data attached to Inoue and Sasaki as in the above case, it will be sent to Sasaki as it is and the size of Inoue exceeds the receivable size. However, since divided reception is possible, the data is divided into 1 megabyte and transmitted. If you try to send a 5-megabyte e-mail to Inoue and Sasaki as well, Inoue will still divide it into 1-megabyte chunks, but Sasaki will be larger than the receivable size, and the split reception Not supported, so do not send.

Next, regarding the part related to receipt confirmation, FIG.
Will be explained. FIG. 3 is a functional block diagram of the electronic mail device for explaining this processing. There are several known methods for confirming receipt of e-mail that has reached the destination, but as a standard method, the one defined in the RFC2298 document issued by the IETF is known. There is. This method allows you to send Disposition-Noti to an email you wish to acknowledge.
If a fication-To header is provided, when the email is received, the receiving device will send a receipt confirmation email in the specified format to the address defined in the field specified in the header. It is a thing. However, many e-mail devices (or e-mail applications) do not support such a receipt confirmation function. Therefore, in this e-mail device, whether or not the other party can confirm receipt is stored in the address book, and only when the receipt confirmation is supported, designation of whether or not to request receipt confirmation is accepted. I am trying. If a request for confirmation of receipt is specified, the Disposition-Noti
A fication-To header is provided.

That is, when an instruction from the user is received,
The sending instruction unit 101 of the CPU 1 shown in FIG. 3 gives an instruction to send an e-mail, but when the destination is selected from the address book, the receipt confirmation availability acquisition unit 111 uses the HDD.
Information of whether or not the other party can confirm receipt is read from the address book stored in the address book storage unit 41 of No. 4. On the other hand, the electronic mail to be transmitted is sent from the transmission instruction unit 101 to the transmission execution unit 104 via the receipt confirmation request adding unit 113. Here, if the recipient can confirm the receipt, the receipt confirmation instruction receiving unit 112 accepts the designation of whether or not the receipt confirmation is desired, and if the receipt confirmation request is designated, the receipt confirmation request is added. The unit 113 adds the Disposition-Notification-To header to the email data and sends the data to the transmission execution unit 104. It is the same as in the case of FIG. 2 that the transmission execution unit 104 drives the network I / F 7 to transmit an electronic mail based on the transmitted data.

For example, when sending e-mails to Suzuki and Tanaka shown in Table 1, even if a request for confirmation of receipt is set, since Suzuki does not support confirmation of receipt, this setting is made for mail addressed to Suzuki. Is ignored and the Disposition-Notification-To header is added only to the corresponding e-mail addressed to Tanaka to confirm the receipt. In addition, Disposition-Notificati
The address defined in the field specified in the on-To header may be the source address or another address. Further, the designation as to whether or not the receipt confirmation is desired may be designated by an input from the user or may be designated by referring to a preset set value. If you want to confirm the receipt, the confirmation email will be returned from the other party, so if you always do this, it will cause unnecessary processing load and increase in traffic, so you can specify whether you want it or not It is preferable to be able to. However, this designation does not make sense if the transmission partner does not support receipt confirmation. Therefore, by performing the above, the processing can be made efficient.

Next, FIG. 4 concerning the part related to language selection
And FIG. 5 will be described. FIG. 4 and FIG. 5 are functional block diagrams of this electronic mail device for explaining this processing. When the main purpose is to send image data or audio data instead of the body text described in an e-mail, a standard cover page may be added as the body. However, if the language used in the cover page is different from the language used by the recipient, the recipient will not be able to read the content. Therefore, in this electronic mail device, the language used by the sender (recipient) is stored in the address book, and the H
When the DD4 is caused to function as a fixed text storage unit to store fixed texts to be added to an e-mail for a plurality of languages and a fixed text in a language different from the language used by the recipient is added to the e-mail to be sent. , The standard sentence is replaced with the standard sentence in the language used by the recipient.

That is, when an instruction from the user is received,
The sending instruction unit 101 of the CPU 1 shown in FIG. 4 gives an instruction to send an e-mail, but when the destination is selected from the address book, the language information acquisition unit 121 stores it in the address book storage unit 41 of the HDD 4. The information of the language used by the recipient is read from the registered address book. On the other hand, the electronic mail to be transmitted is sent from the transmission instruction unit 101 to the fixed text replacement unit 122.
Is sent to the transmission execution unit 104 via. Here, when a fixed phrase is added to the electronic mail to be transmitted and the language used is different from the language used by the recipient, the fixed phrase replacement unit 122 stores it in the fixed phrase storage unit 42 of the HDD 4. A fixed phrase having the same content in the language used by the receiver is selected from the fixed phrases that have been added, the added fixed phrase is replaced with this, and the data is sent to the transmission execution unit 104. Transmission execution unit 10
4 network I / F based on the data sent
To drive 7 to send an e-mail is shown in FIG.
It is similar to the case of.

For example, Tanaka and Carter shown in Table 1
When the user wants to send the image data to, the user creates an e-mail with a Japanese cover page and instructs to send it. Tanaka sends it as it is because the language is Japanese, and Carter uses the language Since it is US English, the cover page is replaced with a US English cover page for transmission.
By doing this, even when sending an e-mail to a partner who uses a different language, it is possible to send an e-mail with a cover page in a language that each sender can understand by creating one mail. It is possible to improve operability and convenience.

Even if the fixed texts to be added to the electronic mail are not stored for all languages, at least a translation means for translating the fixed texts into another language is provided, and instead of replacing the fixed texts, You may make it transmit by translating by a translation means. That is, as shown in FIG. 5, a fixed sentence translation unit 123 may be provided in place of the fixed sentence replacement unit 122, and translation may be performed when necessary. This translation means can be realized by causing the CPU 1 to execute an appropriate application, but it may be configured by dedicated hardware. In this way, when there are various types of fixed phrases, it is possible to reduce the effort for creating fixed phrases of each language and the storage area for storing them. Moreover, if the ability of the translation means is sufficient,
It is possible to easily deal with the case where the details of the fixed phrase are modified, and the convenience can be further improved.

Next, the part relating to the character encoding system will be described with reference to FIG. FIG. 6 is a functional block diagram of the electronic mail device for explaining this processing. When sending an e-mail, the content is coded and sent, but even if characters of the same language are coded, there are a plurality of coding methods. For example,
In e-mail, it is standard to express Japanese in ISO-2022-JP format code, but Shift-JI
There is also a special e-mail environment that is represented by a code in S format or EUC-JP format. Then, if the receiving side encodes the e-mail by using an encoding method that the receiving side does not support, the receiving side cannot decode the e-mail, causing garbled characters, and the recipient cannot read the content.

Therefore, in this electronic mail apparatus, the address book stores the encoding format of the characters that the other party corresponds to, and the characters of the electronic mail are encoded by the encoding system and transmitted. That is, when the instruction from the user is received, the transmission instruction unit 101 of the CPU 1 shown in FIG. 6 instructs the transmission of the e-mail, but when the destination is selected from the address book, the encoded information acquisition unit 131
Reads from the address book stored in the address book storage unit 41 of the HDD 4 the information on the encoding format of the characters corresponding to the transmission partner. On the other hand, the electronic mail to be transmitted is sent from the transmission instruction unit 101 to the transmission execution unit 104 via the encoding method designation unit 132.

Here, the coding method designation unit 132 designates the coding format read by the coding information acquisition unit 131 in the electronic mail to be transmitted and sends the data to the transmission execution unit 104. The transmission execution unit 104 drives the network I / F 7 based on the transmitted data to transmit the e-mail as in the case of FIG. 2, but at this time, the character encoding method is the code. The one specified by the conversion method specifying unit 132 is used. For example, when sending e-mail with the same Japanese text to Suzuki and Tanaka shown in Table 1,
FT-JIS format, Tanaka ISO-2022-JP
Encode in the format and send. By doing this, it is possible to prevent garbled characters without paying particular attention to the transmission.

Next, the part related to the attached file name will be described with reference to FIG. FIG. 7 is a functional block diagram of the electronic mail device for explaining this processing. Although it is common to send a file as an attachment to an email, there are several ways to handle the file name of the attached file. For example, as shown in Table 2. The type 1 in the table is a standard type that conforms to the new standard, but there are many types 8 in Japan.

[0035]

[Table 2]

Therefore, in this e-mail device, the expression format of the attachment file name at the destination is stored in the address book, and when the attachment file is attached to the e-mail to be transmitted, the file of the attachment file is stored. I try to express my name in that form. That is, when the instruction from the user is received, the transmission instruction unit 101 of the CPU 1 shown in FIG. 7 instructs the transmission of the electronic mail, but when the destination is selected from the address book, the attached file name information is acquired. The unit 141 reads the information on the expression format of the file name of the attached file at the transmission partner from the address book stored in the address book storage unit 41 of the HDD 4. On the other hand, the electronic mail to be transmitted is sent from the transmission instruction unit 101 to the transmission execution unit 104 via the attachment file name format designation unit 142.

Here, the attached file name format designation unit 142
File name information acquisition unit 1
The data is sent to the transmission execution unit 104 by designating the expression format of the attached file name of the read type of 41. The network I based on the data sent by the transmission execution unit 104
Driving / F7 to send an e-mail is similar to the case of FIG. 2, but at this time, the expression format of the attached file name is that specified by the attached file name format specification unit 142. For example, when sending an e-mail with an image file in JPEG format with the file name “Test Image” of the Shift-JIS character string to Inoue, Sasaki, Suzuki, and Tanaka shown in Table 1, the email sent for confirmation The attached file names are shown with the headers shown in Table 3, respectively. The numbers of the attached file name type shown in Table 1 represent the contents shown in Table 2, respectively. By doing so, it is possible to express the attached file name in a format that can be handled by the destination device and transmit the e-mail without paying particular attention to the transmission.

[0038]

[Table 3]

Note that the electronic mail device does not necessarily have to perform all of the above-described processing regarding size management, processing regarding receipt confirmation, processing regarding language selection, processing regarding character encoding methods, and processing regarding attached file names. Even when each processing is performed independently, the effect of the processing can be obtained. Further, the information stored in the address book need only be information related to the processing to be executed.
Further, the communication device of the present invention includes all devices having an e-mail transmission function, and includes, for example, a network facsimile device for transmitting image information using e-mail, a mobile phone having an e-mail transmission function, and the like. It includes.

[0040]

As described above, according to the communication apparatus of the present invention, when an electronic mail is to be transmitted by the mail transmitting means to the destination managed by the destination managing means, Since it is possible to refer to the information of the destination stored in the management means in association with the destination and to send the e-mail in a format suitable for that, the user does not have to make individual settings when sending, and the receiving side It is possible to send an e-mail that makes full use of the functions of the device.
