A housing for an apparatus such as a copier has an upper frame and a lower frame which are connected together but are separable from each other such that the upper frame is rotatable with respect to the lower frame to open and close the housing. The lower frame is provide with a handle which is normally contained in the lower frame but can be pulled out when it is desired to lift or transport the apparatus. A locking member is rotatably attached to the lower frame and is slidable engaged with a piece protruding from the upper frame such that the housing can be freely opened and closed if the handle is pushed into the lower frame but that the locking member assumes a position for securely locking the frames if the handle is pulled out of the lower frame.
