Abstract
An automatic document feeder (ADF) with a solid bracket suitable for use with an office machine to separate a plurality of documents one by one, and to feed the separated document to the office machine. The solid bracket comprises a pair of side plates, a stationary belt supporter and a shaftless roller supporter extending between the side plates, and a pair of spring supporters connected to the side plates through individual bent connections. The ADF further includes a rotatable shaft supporting the belt and controlling the tensile force of the belt, and a document separating roller coming into close contact with the belt at a position opposed to a shaftless roller. The tension coil springs are connected between the rotatable shaft and the spring supporters to bias the rotatable shaft and to control the tensile force of the belt. The endless document separating belt is rotatably supported by both the stationary belt supporter and the rotatable shaft. The shaftless roller is supported by the shaftless roller supporter such that it comes into contact with inner surface of the belt while freely shifting upwards and downwards.
