Abstract
A data transmitting apparatus capable of performing highly efficient transmission of data in mixed mode. The data transmitting apparatus comprises an image data block detector for detecting a block composed of image data out of blocks forming a document stored in a picture image memory, and a vacant space detector for detecting a vacant space in excess of a predetermined size in the block detected by the image data block detector, the block being divided into two blocks which are formed by the vacant space and the remaining space, respectively, when the vacant space is detected by the vacant space detector. The data transmitting apparatus is advantageous of transmitting the entire document in a shorter period of time.
