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.
