ABSTRACT:
When a memory read and a facsimile transmission operation are concurrently performed, first it is determined in the memory read operation whether a converting block is available based on the state of an in-use flag. If the converting block is unavailable, namely the converting block is in use by the facsimile transmission operation, the memory read operation goes in a standby state. When the converting block is available, namely the in-use flag is reset on the facsimile transmission operation side, the in-use flag is set indicating that the converting block is in use by the memory read operation. Then, one line of document data is coded and stored in an accumulated memory. Next, after the in-use flag is reset, the above-mentioned process is repeated until all of the document data has been coded. This allows the converting block to be alternately used by the memory read and the facsimile transmission operations.
