Disclosed is a facsimile device enabling high- efficiency data transmission independently of the direction in which an original is drawn into the facsimile device. The facsimile device includes a scanner for reading the original, an image memory for storing a read image signal, a circuit for detecting the direction of text lines of a read pixel signal, a circuit for determining whether or not the text line direction is close to a longitudinal direction or a lateral direction of arrangement of memory cells in the image memory, a circuit for executing an operation for rotating the image signal by a predetermined angle when a determination is made that the text line direction is closer to the longitudinal direction, a compression circuit for reading the rotated image signal in the lateral direction of the arrangement of the memory cells, to compress the read image signal, and a transmission circuit for transmitting the compressed signal onto lines.
