Abstract: A communication terminal device which can send data by means of electronic mail or facsimile. The communication terminal device first tries to send the data by electronic mail over a network. In the meantime, the electronic mail address and facsimile number corresponding to a recipient are both stored in a memory. When a predetermined response is not received from the network during a network connection operation, or when there is mail returned in the sender's mailbox, the communication terminal device dials the facsimile number of the recipient and transmits the mail image data via facsimile communication.

Abstract: A communications terminal device such as a facsimile device with a function of transmitting original document image data to a destination by electronic mail. Before image data transmission to a destination by electronic mail, a main controller of the facsimile device converts the image data on one page of original document to electronic mail data and determines how much volume the image data has. The image data on one page of original document is transmitted to a destination by a single electronic mail when the calculation result does not exceed a prescribed volume. On the other hand, the original image on one page of original document is divided up into smaller pieces of data and transmitted to a destination by a plurality of electronic mails respectively when the calculation result exceeds a prescribed volume.
