1. A currency handling device comprising a thickness detector, the detector comprising:
- a first roller;
a second roller displaceably positioned relative to the first roller along a predetermined path in response to a note passed between the first roller and the second roller;
a roller gear coupled to and movable with the second roller;
a drive gear coupled to the roller gear, wherein the second roller is caused to roll by rotating the drive gear;
a sensor positioned to measure the relative displacement between the first roller and the second roller; and
a processor coupled to the sensor and comprising software for determining a thickness associated with the note based on the relative displacement between the first and second rollers.

Abstract
A currency handling system comprising a fitness detector. The fitness detector comprising a thickness detector, a limpness detector, a soil detector or a combination thereof. The thickness detector comprising an upper roller displaceable in a predetermined arc by a note passing between the upper roller and a lower roller. The limpness detector comprising a single driven crackle roller comprising an elongated central bulge and two outer bulges, wherein the central bulge is in conforming relation to a flexible belt. Sheet metal guides further facilitate note deformation and sound production.

10. A currency handling device comprising a thickness detector, the detector comprising:
-
a first roller having a fixed central axis;
a first roller drive gear coupled to the first roller for causing the first roller to rotate;
a second roller having a displaceable central axis, wherein the second roller is positioned relative to the first roller such that passage of a note between the first roller and the second roller displaces the central axis of the second roller along a predetermined path;
a planetary gear connected to the second roller and coaxial with the central axis of the second roller;
a second roller drive gear coupled to the planetary gear for causing the second roller to rotate, wherein the determined path along which the second roller may be displaced by the note is an arc about the second roller drive gear;
a sensor positioned to measure displacement between the first and second rollers; and
a processor coupled to the sensor for determining thickness of a note based on displacement of the second roller along the predetermined path. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of determining thickness associated with a note, the method comprising:
-
passing a note between a pair of rollers;
allowing the note to displace at least one of the rollers;
restricting displacement of the one roller to a predetermined arced path;
measuring displacement of the one roller; and
determining a thickness associated with the note based on the displacement of the one roller. - View Dependent Claims (22)
