- the device When the device receives an e-mail including the destination e-mail address in the LAN control unit 7, for example, the header information (From) of the e-mail is used as the subject in the master! When recognizing that it is $ trn, the body of this e-mail, that is, the destination e-mail destination is stored in RAM 3 and HD 9, and this is set as the destination e-mail destination. When the number of e-mails exceeds the maximum number of facsimile output, e-mail is forwarded to this e-mail destination.
- the contents of the tag (Page Number) of the body having the TIFF structure are extracted (S81), and the contents of the tag and the maximum output stored in the HD 9 as described above are obtained. It is determined whether the e-mail is to be transferred to the transfer destination e-mail destination based on the number of copies (S82). If the content of the tag (Page Number) is larger than the maximum output number, the body of the e-mail is transferred to the transfer destination e-mail destination by the LAN control unit 7 (S83).
- the body of the e-mail is converted to facsimile data by the e-mail format inverse converter 11 and stored in the HD 9 as described above.
- Email address according to the correspondence table
- the facsimile data is transmitted to the telephone number corresponding to (S84).
- an e-mail can be sent to a predetermined transfer destination e-mail destination even if the content of the tag does not exceed the maximum output number.
- the contents of a large number of received documents can be viewed in advance on a PC display or the like, and paper can be saved.

- it is determined whether the body of the e-mail is encrypted S103). If the body of the e-mail is encrypted, the body of the e-mail is decrypted using the secret key (S104).
- the e-mail text is digitized in accordance with a predetermined rule to create a digi- nent A (S105). Further, the attached digest is decrypted with the public key to create the digest B (S106). On the other hand, if the e-mail is not encrypted, the digest of the e-mail body is quantified according to a predetermined rule to create a digest A (S105), and the attached digest is decrypted with the public key to obtain the digest B. Is created (S106). Next, the digest A and the digest B are compared, and it is determined whether or not they match (S107). If the two digests match, the body of the e-mail is converted to facsimile data by the e-mail format inverse converter 11, and the converted facsimile data is output to the facsimile (S108).
- the private key, secret key, and public key shown in FIGS. 16 and 17 correspond to specific telephone numbers and e-mail destinations, respectively. Also, in the above, the identity of the contents is checked between the facsimile data before decryption and the data of the e-mail after decryption, but before the data after decryption and before decryption. May be used to check the identity of the contents.
- the present invention is not limited to this.
- Data is converted between a network that transmits and receives data based on the network and a network that transmits and receives data based on the telephone number, and transmits and receives data in a specified format to a specified destination. If possible, it can also be applied when two or more LANs and one or three or more telephone lines are connected.
- the facsimile e-mail conversion device of the present invention switches between a telephone line and a LAN in accordance with an instruction, and converts data from facsimile data to e-mail data by conversion means as necessary.
- the facsimile e-mail converter of the present invention is suitable for transmitting and receiving facsimile data and e-mail data between a public line network and a facsimile and a LAN using an existing facsimile apparatus.
