ABSTRACT:
A tilt hinge supports a cover so that the cover can lightly be opened and can be held in an inclined position at an optional angular position. The tilt hinge comprises: a mounting member having a mounting plate and a bearing plate, and attached to a main unit of a machine; a stepped shaft having an expanded section and a reduced section of a diameter smaller than that of the expanded section, supported for rotation on the bearing plate; a support member for supporting a cover, fixed to the shaft; a torsion coil spring wound around the shaft and resiliently engaged between the support member and the mounting member; and a friction mechanism interlocked with the bearing plate and the shaft. The friction mechanism comprises: a first friction plate mounted on a portion of the reduced section of the shaft, extending between one side surface of the bearing plate and the expanded section of the shaft; a spring washer mounted on the portion of the reduced section of the shaft in combination with the first friction plate; a second friction plate mounted on a portion of the reduced section of the shaft, extending between the other side surface of the bearing plate and the upset end of the reduced section of the shaft; and a flat washer mounted on the portion of the reduced section of the shaft in combination with the second friction plate.
