れている。In the figure, 1 is a copying machine main body, and 2 is a document feeding device provided so as to be openable and closable via two sets of opening and closing devices 3 provided on the side surface of the copying machine main body 1. Reference numeral 4 denotes a frame of the document feeding device 2, and a frame reinforcing member 5 is fixed to one side portion of the frame 4 on the pivotal fulcrum side. Then, the frame reinforcing member 5 is fixed by two pairs of frame brackets 6 extended into the frame 4. Each of the opening / closing devices 3 is provided with a pair of opening / closing members 7, and the tip ends of the pair of opening / closing members 7 are rotated by the frame bracket 6 of the document feeding device 2 at the center of gravity of the document feeding device 2. Freely pivot 8
It is connected with. The frame bracket 6 and the opening / closing member 7 are connected by a shaft 9 at a position separated from the center of rotation of the shaft 8. The shaft 9 is tightly fitted to the frame bracket 6, but is fitted to the opening / closing member 7 in an arcuate elongated hole 10 centered on the pivot shaft 8.
