Abstract: If received electronic mail data cannot be printed, an electronic mail control unit (33) transfers the received electronic mail data to another information terminal. A facsimile control unit (34) orders a facsimile unit (27) to print out an error message including sender information and the attached-file format. A display control unit (35) starts a display unit (29).

Description: The present invention relates to an Internet facsimile apparatus for transmitting and receiving image data using an e-mail system according to the preamble part of claim 1 and an information terminal device for use in combination therewith. Generally an information terminal device such as a personal computer comprises a large-capacity memory device and stores all received data at the memory device. A user identifies the data content indicated on a display screen before decides whether or not the data is printed at a printer. On the contrast, since an Internet facsimile apparatus for transmitting and receiving image data using an e-mail system does not have an enough-capacity memory device, it converts the received data into facsimile data sequentially to print, and deletes sequentially the data which printing is completed. A user recognizes the received data content by identifying a recording paper on which the data is printed. The processing of data reception up to printing at a conventional Internet facsimile apparatus is explained using a flow chart in Fig. 1 in the following. First the e-mail data received at an internet facsimile apparatus is temporally stored (ST101 and ST102). And it is decided whether or not the stored data is printable (ST103), then when it is possible to print the stored data, the stored data is converted into a facsimile format and printed (ST104 and ST105). On the other hand, when it is impossible to print the stored data, the stored data is deleted (ST106). As described above, in the case of receiving an unprintable e-mail data, since the conventional Internet facsimile apparatus deletes the data, a user can not recognize that the data is received and either can not identify the data content even using another method. Document EP-A-0 679 013 discloses a data communication apparatus such as a facsimile which is constructed by a communication unit to transmit and receive data, an output unit such as a printer to output the data received by the communication unit, and a connection unit such as a LAN to connect one or more external apparatuses. Data of an output-capable ability of the output unit and data of an output-capable ability of the external apparatus connected through the connection unit are notified to a communication apparatus on the partner side by the communication unit. The ability data indicates an image size and a resolution of image data that can be outputted by the output unit and/or the external apparatus. The data communication apparatus also has a transfer unit to transfer the data received by the communication unit to the external apparatus connected to the LAN. When the image size and resolution of the received image data exceed the output-capable ability of the output unit, the transfer unit transfers the received data. When the data is transferred by the transfer unit, such a fact is notified to the user. Document EP-A-0 652 666 discloses a system and method for computer data transmission. The system processes data for communication between first and second computers by linearizing the communications message. The message comprises a linear header portion, an extended header portion, and a message body. The linear header portion identifies the number of message recipients and message types. The extended header contains detailed information about the message recipients, such as recipient name and address. The extended header may also contain message subject information, polling information and password data. The header information is used by the receiving computer to prepare to process the expected data type. The message body may be transferred in a form that takes advantage of the data processing capabilities of the first and second computers. The computers may exchange data processing capabilities so that the most efficient transfer form may be selected. The system may be readily used in facsimile communication where the first and second computers are facsimile machines. Document US-A-5,521,719 discloses a communication procedure executing unit which executes a predetermined communication procedure using subaddress frame(s). A mail distributing unit distributes electronic mail through the group 3 facsimile communication in the predetermined communication procedure. A subaddress extracting unit extracts information concerning a sub address(es) previously set in the given subaddress frame(s). An address specifying unit specifies addresses to which the mail distributing unit distributes the electronic mail, the specification being performed using the extracted sub-address(es). The object of the present invention is to provide an internet facsimile apparatus in which, when an unprintable e-mail data is received, a user can recognize that the data is received and can identifies the data content. The object of the present invention is achieved by an internet facsimile apparatus with the features of claim 1 and an information terminal device in combination with an internet facsimile apparatus according to claim 13. FIG.1 is a flow chart illustrating the processing of data reception up to printing at a conventional Internet facsimile apparatus; FIG.2 is a network configuration diagram including an Internet facsimile apparatus in the embodiment of the present invention; FIG.3 is a block diagram illustrating a basic configuration of an Internet facsimile apparatus in the embodiment of the present invention; FIG.4 is a function diagram illustrating a function of control section at an Internet facsimile apparatus in the embodiment of the present invention; FIG.5 is a diagram illustrating an example of an error message printed at an Internet facsimile apparatus in the embodiment of the present invention; and FIG.6 and FIG.7 are flow charts illustrating the processing of data reception up to printing at an Internet facsimile apparatus in the embodiment of the present invention. The embodiment of the present invention is explained in detail with reference to drawings in the following. FIG.2 is a network configuration diagram including an Internet facsimile apparatus in the embodiment of the present invention. In FIG.2, the e-mail data transmitted from another Internet facsimile apparatus 11 or personal computer 12 is received at Internet facsimile apparatus 13 in the embodiment of the present invention via the Internet. To communicate via the Internet, the document data of an e-mail is converted into the text format. And the image data, voice data and so on are also converted into the text format, and transmitted and received as an attached file to document data. Internet facsimile apparatus 13 format converts a received data into facsimile data to print. At this time, in the case where the received data includes the data that can not be format converted into facsimile data, it is transferred to another information terminal 14 such as a personal computer. Next the basic configuration of an Internet facsimile apparatus of the present invention is explained with a block diagram in FIG.3. As illustrated in FIG.3, an Internet facsimile apparatus is primarily composed of control unit 21 for providing controls of data identification, data recognition and so on, ROM 22 for storing a program, RAM 23 to be used as a data area of the program, interface section 24 for executing a procedure necessary to transmit and receive data by e-mail, data storing section 25 to store the received data temporally, format converting section 26 for converting the format of the received data, facsimile section 27 for reading an original paper and printing the received data, modem 28 for modulating and demodulating the data transmitted and received between telephone lines and LAN and indication section 29 for notifying the reception of data to a user. Next the function of control unit 21 at an Internet facsimile apparatus in the embodiment of the present invention is explained with a function diagram illustrated in FIG.4. As illustrated in FIG.4, control unit 21 is composed of primarily printing decision section 31 for deciding whether or not the stored e-mail data (hereinafter called "stored data") is printable, specific information extracting section 32 for extracting the necessary information from the stored data, e-mail control section 33 for control the transmission and reception of e-mail data, facsimile control section 34 for controlling the transmission and reception of facsimile data, and indication control section 35 for controlling indication section 29. ROM 22 has template document memory table 36 in which a template document attached to an error message is memorized. RAM 23 is for printing requirement table 37 in which the requirement to print at the Internet facsimile apparatus is registered and transfer address table 38 in which an address to transfer the data is registered. Printing decision section 31 decides whether or not the file format of the stored data at data storing section 25 meets the requirement memorized in advance in printing requirement table 37 at RAM 23. And it outputs the decision result to e-mail control section 33, facsimile control section 34 and indication control section 35. Specific information extracting section 32 predetermines specific codes such as "From:" indicating a mail address of a sender, "Content-Type:" indicating a format of an attached file, and extracts the specific information set by the predetermined specific codes from the stored data. In addition, all of header information may be extracted as specific information. E-mail control section 33 instructs printing decision section 31 to execute the decision processing when e-mail data are stored at data storing section 25. And e-mail control section 33 instructs specific information extracting section 32 to execute the extraction processing when printing decision section 31 decides that the stored is unprintable, concurrently acquires an address of a information terminal device to be transferred from transfer address table 38 and transfers the extracted specific information from interface section 24 to the information terminal device to be transferred . In addition, another method to acquire a transfer destination address is to insert an address of information terminal device to be transferred in head information and read it. By using this method, when the transmitted data is unprintable at an Internet facsimile apparatus, a sender can transfer the data to an information terminal device at the predetermined transfer destination address without other procedures. And e-mail section 33 may acquire an address of the sender from the head information and return the received data to the sender. And e-mail control section 33 transmits the stored data to an information terminal device to be transferred if it gets the transfer instruction from the information terminal device to be transferred . On the contrast, it deletes the stored data if it gets the deleting instruction from the information terminal device to be transferred . And in the case where printing decision section 31 decides that the stored data is printable, facsimile control section 34 instructs format converting section 26 to convert the stored data into the facsimile data and instructs facsimile section 27 to print the converted facsimile data. And in the case where printing requirement decision section decides that the stored data is unprintable, facsimile control section 34 instructs format converting section 26 to convert the specific information extracted at specific information extracting section 32 into the facsimile data and instructs facsimile section 27 to print an error message including the converted specific information attached a template document registered in template document table 36 at ROM 22. In the case where printing decision section 31 decides that the stored data is unprintable, indication control section 35 start up indication section 29. The start up of indication section 29 includes indicating a ramp or buzzing a buzzer. By this manner, a user can confirm that the reception of the data unprintable at an Internet facsimile apparatus early, which allows him/her to take an action to deal it fast, such as transferring the received data to another information terminal device and identifying the content at the information terminal device to be transferred . In addition, to use a printer at facsimile section 27 effectively, the apparatus in the embodiment of the present invention has the configuration where format converting section 26 converts the stored data into the facsimile data such as MH data and outputs it to facsimile section 27, then facsimile section 27 converts the facsimile data into the printable data and prints it. However the configuration of the apparatus according to the present invention is not limited by the embodiment described above. It is also preferable that format converting section 26 converts the stored data into the facsimile data, further converts it into the printable data and outputs it to facsimile section 27. For instance, in the case where the Internet facsimile apparatus receives the text data, format converting section 26 converts the character code data into the bit map data and outputs it to facsimile section 27. Next FIG. 5 is used to illustrate an example of an error message printed at facsimile section 27 at an Internet facsimile apparatus in the embodiment of the present invention. As illustrated in FIG.5, an error message is composed of a mail address of a sender recorded after "From:", header information including a format of attached file recorded after "Content-Type:" and a template document. By seeing the content of the error message, since a user can confirm the reception of data unprintable at the Internet facsimile apparatus and the sender of the data, he/she can take an action to deal it fast such as notifying that the reception of the unprintable data to the sender. Next flow charts in FIG.6 and FIG.7 are use to explain the processing of data reception up to printing at an Internet facsimile apparatus in the embodiment of the present invention. First an e-mail transmitted from a personal computer or another Internet facsimile apparatus is received interface section 24 via the Internet (ST601) and stored temporally at data storing section 25 (ST602). Next printing decision section 31 compares the stored data with the requirements registered in printing requirement table 37 and decides whether or not it is printable (ST603). For instance, in the case where it is registered in printing requirement table 37 that the printable data format is only TIFF and the printable data capacity per a page is less than 1MB, printing decision section 31 first decides whether or not the data is the TIFF format. If the stored data is the TIFF format, it is decided whether or not the data volume per a page of the stored data is less that 1MB. In the case where the stored data is decided printable, by the instruction from facsimile control section 34, the stored data is converted into the facsimile data at format converting section 26 (ST604) and printed at facsimile section 27 (ST605). And in the case where the stored data is decided unprintable, indication section 29 is first started up by the instruction from indication control section 35 (ST606). By this manner, a user can confirm the reception of the data unprintable at the Internet facsimile apparatus. Concurrently e-mail control section 33 decides whether or not the stored data can be transferred to another information terminal device (ST607). The decision on the transfer is performed by deciding whether or not the transfer flag is set, in other words, another information terminal device is prepared as a transfer destination. In addition, it is possible to designate the sender as an information terminal device to be transferred . In the case where the stored data can not be transferred, the header information is extracted from the stored data at specific information extracting section 32 (ST608), to which a template document registered in ROM 22 is attached, then the error message is generated (ST609). The generated error message is, by the instruction from facsimile control section 34, converted into the facsimile data at format converting section 26 (ST610) and printed at facsimile section 27 (ST611). By this manner, a user can confirm the sender of the received data, which permits him/her to take an action to deal it fast such as notifying the sender that the reception of the unprintable data. And after the error message is printed, the stored data is deleted by the instruction from e-mail section 33 (ST612). In the case where the stored data can be transferred, e-mail control section 33 acquires an address of an information terminal device to be transferred (ST613). As a method to acquire the address, for instance, to insert an address of an information terminal device to be transferred in head information of the data, to register in advance an address of an information terminal device to be transferred in RAM and to designate it every time by inputting with key by receiver are considered. Next specific information extracting section 32 extracts specific information including a mail address of a sender and an attached file format from head information of the stored data (ST614), and e-mail control section 33 instructs to transmit the specific information to the information terminal device to be transferred. By this manner, a user of the information terminal device to be transferred can obtain the information on the sender of the data, and select whether the data is transferred or deleted. In the case where an information terminal device to be transferred instructs to transfer the data (ST616), e-mail control section 33 instructs to transfer the stored data to an information terminal device to be transferred (ST617). And facsimile section 27 prints the transfer result as log information (ST618). In the case where an information terminal device to be transferred instructs to deleted the data (ST619), or in the case where the rest capacity of a memory device at an Internet facsimile device is reduced, for instance in the case where another data is received without any instruction (ST620), e-mail control section 33 instructs to delete the stored data (ST621). In addition in the present invention, although the specific information is transmitted before the stored data is transferred to an information terminal device to be transferred , it is also preferable to transfer the stored data immediately after the address acquisition depending on the user's requirement. And even in the case where the stored data was transferred, it is possible to print an error message by programming the operation of the control unit. And in the case where a part of the stored data is printable, it is possible to print only the part by programming the operation of the control unit. As described above, the present invention can provide the Internet facsimile apparatus in which, in the case of receiving an unprintable e-mail, a user can recognizes the reception of the data and identifies the data content.
