Abstract

PROBLEM TO BE SOLVED: To easily carry an image forming device such as a large-scale copying machine provided with a reader on a device main body and a paper feeder under the device main body. SOLUTION: A reader 13 is positioned on a device main body 12 of a copying machine by fitting a recessed part 28 and a projecting part 34 for positioning together and freely attachably/detachably mounted on the device main body 12 by engaging a pin 20 for mounting with a hole. A paper feeder 11 is positioned under the device main body 12 by fitting the hole for positioning and a pin 15 together and freely attachably/detachably mounted on the device main body 12 by engaging the pin 20 for mounting with the hole. Then, when the device is installed, for example, at a user's side (at the initial installation) or the place of installation is changed (at the change of the place of installation), the device is separately carried by dividing the device into the device main body 12, the reader 13 and the paper feeder 11.
