Communication terminal apparatus

A communication terminal device(200) of the present invention, having a function for transfer of file data such as code data and binary data, can relay or broadcast file data received from another communication terminal device(100) to yet another communication terminal device(301, 302). When the communication terminal(302) device as the relay destination is not able to receive file data, the communication terminal device(200) of the present invention converts the received file data to facsimile coded data and transmit it. For that purpose, the communication terminal device(200) is provided with a character generator(20) that converts code data to image data.
