Abstract

A belt and compression pad system provides a low cost, space efficient, one-at-a-time document feed and transport. Applications, such as bank self-service terminals, require this type of feed for documents such as receipts, checks and envelopes. Referring to Fig. 1B, it is seen that belt 1 and its pulley 2 are located between compression pads 3. Fig. 1A shows that pulley 2 carries belt 1 below the upper surface of compression pads 3. Compression pad 3, a soft foam, is sandwiched between MYLAR* upper surface 4 and steel backer plate 5. The belt is of a material with a much higher coefficient of friction than the MYLAR. In Fig. 2 it is seen that when document 6 is introduced to belt 1, and is bridging the space between the two pads 3, it is pulled atop the pads, compressing the foam.

In Fig. 2 it is seen that when document 6 is introduced to belt 1, and is bridging the space between the two pads 3, it is pulled atop the pads, compressing the foam. Since the friction between belt and document is greater than the friction between the document and the MYLAR, the document is carried forward by the moving belt and ejected at the end of the path. * Trademark of E.
