Embodiment 1

[0053] An embodiment of the present invention will be described below with reference to the drawings.

[0054] The network communication system is, for example, as shown in FIG. 2 , composed of terminal devices (communication devices) 21, 25 including, for example, network facsimile devices having a communication function via a network, mail servers 22, 24, and a network 23 such as the Internet. In addition, in the same figure, only one terminal device 21 on the sending side and one terminal device 25 on the receiving side are shown, but a plurality of each may be connected to the network 23 .

[0055] In this figure, the e-mail sent from the sender's terminal device 21 to the sender's mail server 22 is transmitted to the recipient's e-mail through the network 23 in accordance with an e-mail transfer protocol specified such as SMTP (Simple Mail Transfer Protocol). The server 24 is stored in the mail server 24. The terminal device 25 on the receiving side regularly accesses th...

Embodiment 2

[0105] Another embodiment of the present invention will be described below with reference to the accompanying drawings.

[0106]Here, according to the flow charts of FIG. 8 and FIG. 9 , in the terminal device 21 of the sender, by managing the free capacity of the image storage unit 6 that stores the data received from the mail server 22, the function when receiving the above-mentioned response mail with priority To illustrate.

[0107] As shown in FIG. 8, in the terminal device (fax / email device) 21 of the sender, at first connect to the mail server 22 (S21), obtain the unique ID and the information number list of each e-mail stored in the mail server 22 ( S22).

[0108] Next, in the terminal device 21, according to the relationship between the data size of the e-mail identified by the unique ID and the free capacity of the image storage unit 6, a predetermined receiving process is performed (S23), and the received e-mail is stored in the image storage unit. 6.

Abstract

In a communications device, a terminal machine transmits / receives data over a network and makes a request for a response to a data transmission from a receiving-end machine. In the terminal machine, an e-mail message identifying unit determines whether data to be received over the network is response data to the response request, and a main control unit controls so as to preferentially receive data identified as the response data by the e-mail message identifying unit over other data. Thus, if an e-mail message is transmitted with a request for a disposition verification, a reply message to the disposition verification request can be quickly received from the receiving-end machine.

Description

technical field [0001] The present invention relates to a communication device that transmits data such as image information through a network, and more specifically relates to a communication device that has a function of requesting a response from a transmission destination and confirming the presence or absence of the response while transmitting the data according to a predetermined transmission setting . Background technique [0002] With the development of networking in recent years, network communication devices for sending and receiving electronic mail (E-mail) through networks such as the Internet have been used in various applications. [0003] As such a network communication device, there is known a scanner function, but it is not only used as a device for reading images, but can send the read image information as an attachment of the aforementioned e-mail to a network connection computer and other devices. [0004] As a network communication device having the ab...
