ABSTRACT:
An image reader includes a scanner for reading a two-dimensional image and converting the read data into two-dimensional image data, a memory for storing the two-dimensional image data, correction circuit for correcting the two-dimensional image data so that the direction of character strings included in the two-dimensional image data coincides with the main scanning direction, and a coding circuit for reading the corrected two-dimensional image data from the memory in the order along the main scanning direction. The facsimile machine includes such an image reader, and a transmission circuit for transmitting the coded image data to another facsimile machine.
