Abstract

An apparatus and method are disclosed for supporting a flat belt member. The apparatus includes a drum member rotatable about a longitudinal axis of rotation and comprising an outer support surface that generally increases in diameter from a first end region to a central region and decreases in diameter from the central region to a further end region. The central region includes a groove in the support surface which extends circumferentially around the drum member. A ring member is located in the groove.

First claim

What is claimed is:

1. Apparatus for supporting a flat belt member, the apparatus comprising:
a drum member rotatable about a longitudinal axis of rotation and including an outer support surface that generally increases in diameter from a first end region to a central region and decreases in diameter from the central region to a second end region, wherein the central region has a groove in the outer support surface extending circumferentially around the drum member;
a ring member located in the groove to (i) support a flat belt member, (ii) prevent slippage between the flat belt member and the drum member, and (iii) imbue an arcuate cross-section into a sheet-like item of media and thereby to increase rigidity of the sheet-like item of media when the sheet-like item of media is sandwiched between belts; and
first and second guide arms to move in common with one another, each guide arm to engage side regions of the item of media as the item of media is thrust out between the belts and each guide arm lifts in response to a leading edge of the item of media exiting between the belts having the increased rigidity, and each guide arm lowers in response to a trailing edge of the item of media ejected from the belts and in response to a decrease in rigidity of the item of media, and when the guide arms are lowered, the item of media is presented at an exit orifice of the apparatus.

2. The apparatus as claimed in claim 1 , wherein the ring member is manufactured from a material that has a co-efficient of friction of at least about around 0.70.

3. The apparatus as claimed in claim 2 , wherein the coefficient of friction is at least about around 0.90.

4. The apparatus as claimed in claim 3 , wherein the coefficient of friction is at least about around 1.00.

5. The apparatus as claimed in claim 1 , wherein the ring member comprises a rubber “O” ring.

6. The apparatus as claimed in claim 1 , wherein the drum member comprises a crown roller.

7. The apparatus as claimed in claim 1 , wherein the ring member is arranged to substantially prevent slippage between the drum member and an inner abutting surface of a flat belt member.

8. The apparatus as claimed in claim 1 , wherein the groove has a substantially U-shaped cross-section or a substantially V-shaped cross-section or a substantially semi-circular cross-section.

9. The apparatus as claimed in claim 1 , wherein the ring member has a substantially circular cross-section or a substantially rectangular cross-section.

10. An automated teller machine (ATM) or self-service terminal comprising:
a media item transport mechanism for conveying sheet-like items of media from a first end of a media item transport path to a second end of the media item transport path, the media item transport mechanism including (i) a drum member rotatable about a longitudinal axis of rotation and including an outer support surface that generally increases in diameter from a first end region to a central region and decreases in diameter from the central region to a second end region to form a generally crowned central region of the rotatable drum member, wherein the crowned central region has a groove in the outer support surface of the drum member, (ii) a ring member extending around the crowned central region of the rotatable drum member in the groove, (iii) a flat endless belt member which rides on the ring member at the crowned central region of the outer support surface to imbue an arcuate cross-section into a sheet-like item of media and thereby to increase rigidity of the sheet-like item of media as the drum member rotates about its longitudinal axis of rotation to convey the sheet-like item of media from the first end of the media item transport path to the second end of the media item transport path, wherein the sheet-like item of media is sandwiched between belts, and (iv) first and second guide arms to move in common with one another, each guide arm to engage side regions of the item of media as the item of media is thrust out between the belts and each guide arm lifts in response to a leading edge of the item of media exiting between the belts having the increased rigidity, and each guide arm lowers in response to a trailing edge of the item of media ejected from the belts and in response to a decrease in rigidity of the item of media, and when the guide arms are lowered, the item of media is presented at an exit orifice of the ATM or self-service terminal.

11. An apparatus, comprising:
a rotatable crowned drum member having a groove in an outer support surface of the rotatable crowned drum member;
a ring member situated in the groove of the crowned drum member and configured to: (i) prevent slippage between the flat belt member and the crowned drum member, and (ii) imbue an arcuate cross-section into a sheet-like item of media and thereby to increase rigidity of the sheet-like item of media when the sheet-like item of media is sandwiched between belts; and
first and second guide arms to move in common with one another, each guide arm to engage side regions of the item of media as the item of media is thrust out between the belts and each guide arm lifts in response to a leading edge of the item of media exiting between the belts having the increased rigidity, and each guide arm lowers in response to a trailing edge of the item of media ejected from the belts and in response to a decrease in rigidity of the item of media, and when the guide arms are lowered, the item of media is presented at an exit orifice of the apparatus.

12. A method of operating a media item transport mechanism in an automated teller machine (ATM) or self-service terminal, the method comprising the steps of:
providing a groove in a central region of an outer support surface of a rotatable crowned drum member of the media item transport mechanism;
providing a ring member extending around the outer support surface of the crowned drum member in the groove;
locating a flat belt member on the ring member at the central region of the crowned drum member as the belt member rides on the ring member to imbue an arcuate cross-section into a sheet-like item of media and thereby to increase rigidity of the sheet-like item of media when the sheet-like item of media is sandwiched between belts;
lifting two guide arms in response to a leading e of the item of media having the increased rigidity as the item of media exits the belts and engaging, by the guide arms, side regions of the item of media as the item of media is thrust out between the belts;
lowering the two guide arms in response to a trailing edge of the item of media ejected from the belts and in response to a decrease in rigidity of the item of media; and
presenting, at an exit orifice of the ATM or self-service terminal, the item of media once the guide arms are lowered.

13. A media item transport mechanism for an automated teller machine (ATM) or self-service terminal, the media item transport mechanism comprising:
an endless flat belt member having an inner abutting surface;
a drum member rotatable about a longitudinal axis of rotation and including an outer support surface that generally increases in diameter from a first end region to a central region and decreases in diameter from the central region to a second end region, wherein the central region has a groove in the outer support surface extending circumferentially around the drum member;
a ring member located in the groove and extending around the outer support surface which extends circumferentially around the drum member to (i) provide a non-slip surface between the ring member and the inner abutting surface of the endless flat belt member, and (ii) imbue
