Abstract

Document 1 is normally driven by feed mechanism 2 that rotates ring gear 3 in the direction of arrow A. Gear 3 engages planetary gears 4. The latter are free to rotate about pins secured to carrier 5 to effect rotation of sun gear 6 and also document feed roll 7 which is rigidly secured to gear 6 by shaft 8. Carrier 5, journaled about shaft 8, is urged in the direction of arrow 13, but is restrained by gear sector 9 which engages fixed stop 10. To advance document 1 for viewing, sector 9 is rotated in the direction of arrow C while feed mechanism 2 is stopped and gear 3 is held stationary. Rotation of carrier 5 in the direction opposite that indicated by arrow B causes gear 6 and feed roll 7 to be rotated in the same direction as when driven by feed mechanism 2.

To advance document 1 for viewing, sector 9 is rotated in the direction of arrow C while feed mechanism 2 is stopped and gear 3 is held stationary. Rotation of carrier 5 in the direction opposite that indicated by arrow B causes gear 6 and feed roll 7 to be rotated in the same direction as when driven by feed mechanism 2. When document 1 has been viewed, rotating sector 9 back to the position abutting stop 10 restores document 1 to the position from which it was advanced for viewing.
