摘要： The present invention relates to an automatic conveying device for use in an image copying machine. The automatic conveyor (4) comprises a main portion (14) mounted to pivot between a closed position to cover a transparent plate (8) and an open position to expose the transparent plate (8). Document conveying means (74) convey a document along the transparent plate (8) when the main portion frame member (70) is placed in the closed position. The main portion frame member (70) is mounted via a hinge mechanism (72) so as to be pivotally coupled to the housing (6) at a position at the back of the center of gravity of the main portion (14). A resiliently urging means (264) is interposed between the movable frame member and a pivoting member (182) of the hinge mechanism (72), in order to impart a balancing rotational moment of a required amount to the frame member (70).

摘要： The present invention relates to an automatic document conveying device suitable for use in an image forming apparatus. The conveying device comprises a main portion (14) mounted for movement between a closed position to cover a transparent plate (8) and an open position which exposes the transparent plate (8). A conveyor belt mechanism comprises a driven roller (76) and a follower roller (78) as well as a plurality of pressing rollers (80, 82, 84, 86) disposed therebetween. The pressing rollers are adapted for vertical movement and are downwardly urged to press the lower portion of an endless belt (88) onto the transparent plate (8). At least one (84, 86) of the pressing rollers has a diameter greater than the diameter of the driven roller (76) and the follower roller (78) in order to prevent the upper portion of the endless belt (88) from slackening in the downward direction.
