Abstract:
A photoreceptor web steering apparatus for a printer comprising:a frame;a shaft rotatably installed at said frame;a guide roller, rotatably installed at said shaft, for guiding circulation of a photoreceptor web having an image area having at least one side, and a plurality of non-image areas located at each side of the image area, as a portion of an outer circumference of said guide roller supports said image area;a steering roller, arranged at said shaft next to said guide roller as a portion of an outer circumference of said shaft, said steering roller supporting at least one of the non-image areas, and comprising:a spacer installed on said outer circumference of said shaft to tilt at a predetermined angle with respect to an outer circumferential direction of said shaft; anda tilting shell rotatably installed on an outer circumference of said spacer and having an outer circumferential surface of said tilting shell being in contact with said photoreceptor web, said tilting shell correcting a lateral slip of said photoreceptor web which contacts an outer circumference of said tilting shell, by changing an inclination direction of said spacer according to a rotational position of said shaft; andmeans for driving said shaft, said driving means installed at said frame and said shaft, for controlling a rotational position of said shaft;wherein said outer circumferential surface of said tilting shell is a processed surface to increase a frictional force between said photoreceptor web and said tilting shell.
