Abstract

PURPOSE:To attain the effective control of communication by practically using a password within facsimile communication data. CONSTITUTION:When the password within reception data of the public line of a facsimile part 4 is decoded, CPU of an external device 3 executes communication with CPU of a reader part 1 and reception data is outputted to a printer part 2 with the reader part 1 if printing-out is possible at the time of coincidence with a register password code. At the time of printing-out, the counter of copying by the classification of departments is updated. At the time of non- coincidence, reception data is transfered to a file part 5 and stored in an external storage device 520. A user inputs the password so that the data can be printed-out from the device 520. A special ID is registered in an image forming device and paper size change, output data variable power and image data rotation, etc., are possible concerning reception data coinciding with it. Thus, department control in the image forming device is easily executed and, in the meantime, the automatic printing-out of reception data which is not scheduled is prevented.
