Abstract: When any of the functions: copier function, printer function and facsimile function, are not being performed, the function information display portion provides display messages ‘Copier available’, ‘Printer available’ and Fax available’, using the display areas equal in size, arranged in the vertical direction. When a print request is given from an external apparatus, the function information display portion provides a display message ‘Printer function engaged’ along with the image processing operating conditions and provides display messages ‘Copier function partly available’ and ‘Facsimile function partly available’ in the left and right halves of the display section. While the printer function is in progress, the information relating to the printer function is displayed in the display area four times as large as that for the copier function and that for the facsimile function.
