ABSTRACT:
The present invention provides a sheet conveying apparatus for conveying a sheet comprising a convey member for applying a conveying force to a sheet, a drive source for driving the convey member, and a drive transmitting means for transmitting a drive force from a first drive transmitting member attached to the drive source to a second drive transmitting member attached to the convey member through one or more speed reduction members stepwisely. Among the first drive transmitting member, second drive transmitting member and speed reduction members, manufacturing accuracy of the speed reduction member disposed at a front stage of the second drive transmitting member is greater than manufacturing accuracies of the other members.
