Abstract

Claims (57)

1. Apparatus for guiding an item of media travelling along a pre-determined transport pathway, comprising:

a guide body comprising an arcuate guide surface;

at least one drive roller comprising an outer drive surface; and

at least one pulley member having an outer item engaging surface that extends through an opening in the guide surface and is urged against the outer drive surface;

wherein the drive roller and pulley member engage opposite sides of an item to lift the item away from the guide surface at an arcuate region of the transport pathway.

2. The apparatus as claimed in claim 1 , further comprising:

the guide body comprises at least one pulley shaft support comprising a substantially C-shaped slot having an inner generally curved surface region and a substantially linear abutment surface region.

3. The apparatus as claimed in claim 2 , further comprising:

the at least one pulley member comprises at least a pair of pulley members each having a groove extending circumferentially around a respective circular engaging surface and arranged to rotate about a respective pulley shaft supported in a respective pulley shaft support of the guide body wherein a resilient “O” ring member is looped around the grooves in the pair of pulley members.

4. The apparatus as claimed in claim 3 , further comprising:

the groove in each pulley member has a depth greater than a cross-sectional thickness of the “O” ring member.

5. The apparatus as claimed in claim 3 , further comprising:

as an item of media is located between the outer drive surface of the roller and the engaging surface of at least one pulley member, the drive shaft of the at least one pulley member is located against the linear abutment surface region of a respective pulley shaft support to increase tension in the “O” ring member.

6. The apparatus as claimed in claim 3 , further comprising:

the at least one drive roller comprises a plurality of drive rollers arranged axially along a common drive shaft; and

the at least a pair of pulley members comprises a plurality of pairs of resiliently connected pulley members juxtaposed against a respective one of the plurality of drive rollers.

7. The apparatus as claimed in claim 1 , further comprising:

the arcuate guide surface has a first radius of curvature and the drive surface is substantially cylindrical having a radius of curvature substantially equal to the first radius of curvature.

8. The apparatus as claimed in claim 1 , further comprising:

the drive roller and pulley member co-operate to simultaneously rotate and pinch said an item therebetween at a moving pinch point.

9. The apparatus as claimed in claim 1 , further comprising:

said item of media is guided from a portion of the transport pathway in which the item travels in a first direction of travel to a further portion of the transport pathway in which the item travels in a further direction of travel, said further direction being about around 75° to 135° from the first direction.

10. An automated teller machine (ATM) comprising:

an apparatus for guiding an item of media travelling along a pre-determined transport pathway, including

a guide body comprising an arcuate guide surface;

at least one drive roller comprising an outer drive surface; and

at least one pulley member having an outer item engaging surface that extends through an opening in the guide surface and is urged against the outer drive surface;

wherein the drive roller and pulley member engage opposite sides of an item to lift the item away from the guide surface at an arcuate region of the transport pathway;

wherein the item of media comprises a currency note.

11. A method for guiding an item of media travelling along a pre-determined transport pathway, comprising:

urging an item of media along an arcuate guide surface of a guide body;

driving at least one drive roller comprising an outer drive surface to thereby engage an outer item engaging surface of at least one co-operating pulley member that extends through an opening in the guide surface and rotate the at least one co-operating pulley member; and

lifting the item away from the guide surface at an arcuate region of the transport pathway via the rotating item engaging surface when the item is between the outer item engaging surface of the at least one co-operating pulley member and the outer drive surface of the at least one drive roller.

12. The method as claimed in claim 11 , further comprising:

guiding said item from a portion of the transport pathway in which the item travels in a first direction of travel to a further portion of the transport pathway in which the item travels in a further direction of travel which is about around 75° to 135° from the first direction.

13. The method as claimed in claim 11 , further comprising:

supporting a pulley shaft of the pulley member in a substantially C-shaped slot comprising an inner generally curved surface region that includes a substantially linear abutment surface; and

urging the pulley shaft against the linear abutment surface as the item of media is pinched between the drive roller and the pulley member.

14. The method as claimed in claim 13 , further comprising:

as the pulley shaft is urged against and rides along the linear abutment surface, simultaneously and automatically increasing an urging force by stretching a resilient “O” ring that is arranged to urge the pulley towards the roller.

15. Apparatus for guiding an item of media travelling along a pre-determined transport pathway, comprising:

a guide body comprising an arcuate guide surface and at least one pulley shaft support including a substantially C-shaped slot having an inner generally curved surface region and a substantially linear abutment surface region;

at least one drive roller comprising an outer drive surface; and

at least one pulley member having an outer item engaging surface that extends through an opening in the guide surface and is urged against the outer drive surface, wherein the at least one pulley member includes at least a pair of pulley members each having a groove extending circumferentially around a respective circular engaging surface and arranged to rotate about a respective pulley shaft supported in a respective pulley shaft support of the guide body wherein a resilient “O” ring member is looped around the grooves in the pair of pulley members;

wherein the drive roller and pulley member co-operate to lift an item away from the guide surface at an arcuate region of the transport pathway.

16. Apparatus for guiding an item of media travelling along a pre-determined transport pathway, comprising:

a guide body comprising an arcuate guide surface having a first radius of curvature;

at least one drive roller comprising a substantially cylindrical outer drive surface having a radius of curvature substantially equal to the first radius of curvature; and

at least one pulley member having an outer item engaging surface that extends through an opening in the guide surface and is urged against the outer drive surface;

wherein the drive roller and pulley member co-operate to lift an item away from the guide surface at an arcuate region of the transport pathway.

17. A method for guiding an item of media travelling along a pre-determined transport pathway, comprising:

urging an item of media along an arcuate guide surface of a guide body;

driving at least one drive roller comprising an outer drive surface to thereby rotate at least one co-operating pulley member that comprises an outer item engaging surface that extends through an opening in the guide surface;

lifting the item away from the guide surface at an arcuate region of the transport pathway via the rotating item engaging surface;

supporting a pulley shaft of the pulley member in a substantially C-shaped slot comprising an inner generally curved surface region that includes a substantially linear abutment surface;

urging the pulley shaft against the linear abutment surface as the item of media is pinched between the drive roller and the pulley member; and

as the pulley shaft is urged against and rides along the linear abutment surface, simultaneously and automatically increasing an urging force by stretching a resilient “O” ring that is arranged to urge the pulley towards the roller.
