Abstract
The invention provides a paper feeder apparatus having first and second automatic paper feeder mechanisms and a manual paper feeder mechanism. The paper feeder apparatus performs automatic feed using the manual paper feeder mechanism and the first automatic paper feeder mechanism. The paper feeder apparatus also has the second paper feeder mechanism which is detachably mounted in the manual paper feeder mechanism. Furthermore, the paper feeder apparatus has a display unit. When the second automatic paper feeder mechanism is mounted in the copying machine, a display control circuit (microcomputer) controls to display a sign at the display unit to indicate which one of the first and second paper feeder mechanisms is selected. However, when the second automatic paper feeder mechanism is not mounted, the display control circuit controls the display unit so as not to display the sign which indicates the selected mechanisms.
