Abstract
A hinge device which can be readjusted easily by bringing a rotating member into contact with a friction member. A first fixing member 10 fixed to a copying machine 1 and a second fixing member 11 fixed to an ADF 2 are connected to each other by means of a first shaft member 13 bearing them so as to be free to rotate; the member 10 has a rotating member 7 fixed to a second shaft member 16 arranged in parallel with the shaft member 13. The member 7 is put into contact with a friction member 15 arranged on the shaft member 13 to form a frictional portion. The member 15 is always in contact with the member 7 on its surface. A hole for bearing the shaft member 16 is an oblong hole 14, with its bottom surface which allows the shaft member 16 to take rocking motions for an arbitrary adjustment of a contact pressure to the member 7. A third shaft member 18 is arranged as a shaft at the other end of the member 11 apart from the portion where the shaft member 13 is arranged, with a spring put between the shaft member 18 and the shaft member 16.
