Abstract
A conventional facsimile machine re-dials by using another telephone line after an elapse of a predetermined period of time since when a communication error after a line connection has occurred, so that it takes a predetermined period of time to re-dial by using the other telephone line, and hence a receiving end may receive data transmitted from another facsimile machine during this period. In order to prevent that, a facsimile machine of the present invention comprises: a plurality of line connecting means, each of which has a telephone line for transmitting/receiving data; a line selecting section for selecting a telephone line to be used when a plurality of telephone lines are connected; and an auto-dial sending section for changing over the telephone line currently selected by the line selecting section to another telephone line so as to make a call immediately, when the receiving end is busy.
