ABSTRACT:
A facsimile machine including an image retrieval unit for retrieving image data from an image of a document; a retrieval buffer memory for temporarily storing the image data retrieved by the image retrieval unit; an encoder for producing encoded data by encoding the image data stored in the retrieval buffer memory; a memory for storing the encoded data when the encoded data is not immediately transmitted after being encoded by the encoder; a transmission buffer for temporarily storing the encoded data before transmission of a facsimile transmission; and a buffer memory usage switching unit for switching use of the retrieval buffer memory and the transmission buffer so that the transmission buffer memory is used as a portion of the retrieval buffer memory when the encoder processes the image data for storage as encoded data in the memory.
