Abstract
An image forming device such as a copier has separate upper, middle and lower units which are mutually openable. The axes of rotation around which the upper unit can rotate with respect to the middle unit and the middle unit with respect to the lower unit are symmetrically disposed and engaging and locking mechanisms are provided such that when one of the pairs of mutually openable units is opened, the other pair is prevented from opening. Thus, the overall equalibrium of the device is not lost even if both pairs of units are opened.
