Document Feeder Transport Belt

A copier's document feeder includes a vacuum belt having small holes, through which vacuum force is applied to the original document. These holes are formed at an angle, so as to eliminate copying of the holes pattern onto the copy paper.

Automatic document feeders of the type used with xerographic copiers use a document transport belt to transport a document to a platen whereat the moving document is stopped for copying. One form of such a feeder uses a vacuum, belt against which the document is held. The plane of this belt is therefore the image plane of the copier's optics assembly. When a document does not cover the entire image plane area, light can reflect off these small holes, and the hole pattern my appear as a dot pattern on the borders of the copy paper.

This dot pattern is eliminated by forming holes 10 at an angle to the plane of belt 11. For example, holes 10 can be laser drilled into the belt at an angle, as shown. For simplicity, only a few of the many holes 10 are shown.
