Abstract
An operation/display panel is attached to an outer surface in front of a printer body, and a duplex unit is detachably attached between the operation panel and the outer surface of the printer body. The duplex unit functions to return the copy paper ejected from an ejecting outlet and having an image on one side thereof toward a paper feeding inlet of the printer body to provide two-sided copying/printing. The operation panel includes operating switches and/or a display, and is slidably mounted such that a space is provided between the operation panel and the printer body, and the duplex unit can then be inserted into the space when two-sided printing/copy is desired.
