Abstract
A document handling apparatus is disclosed which is particularly well adapted for counting documents of value, such as banknotes. The document handling apparatus comprises an input module for receiving a stack of documents and feeding them one by one into the apparatus, a detector box which houses a series of detectors for detecting characteristics of the documents, a transport system for conveying documents within the apparatus, a doubles detector for sensing the passage of each document therethrough and a stacker module for stacking the output documents and presenting them to the user. The apparatus is based on a metal framework in a plastics housing.

1-57. (canceled)
A document sensing assembly for detecting the passage of documents therethrough, the document sensing assembly comprising a shaft;
- at least one roller assembly mounted on the shaft;
- guide surface, the roller assembly cooperating with the guide surface to define a nip therebetween;
- sensing means for sensing deflection of the at least one roller assembly relative to the guide surface in response to a passage of one or more documents through the nip between the roller assembly and the guide surface;
- and monitoring means for monitoring sensed deflections;
- wherein the shaft comprises at least an eccentric portion on which the at least one roller assembly is mounted, such that the size of the nip defined between the roller assembly and the guide surface can be adjusted by rotation of the shaft.
A document handling apparatus comprising a roller assembly, a guide surface, the guide surface opposing the roller assembly to define a nip therebetween, and an eccentric shaft being rotatably mounted in a fixed relation to the roller assembly, wherein the guide surface is movably mounted relative to the roller assembly, and the eccentric shaft capable of urging the guide surface toward the roller assembly to a greater or lesser extent depending on a degree of rotation of the shaft, to thereby adjust a size of the nip, wherein the guide surface is supported by a plate which is pivotable relative to the roller assembly via a pivot point located at one end of the plate, the eccentric shaft being arranged to pass through an aperture located at an other end of the plate, the other end of the plate being distal from the pivot point, and bear upon the aperture to a greater or lesser extent depending on the degree of rotation of the shaft, to thereby pivot the plate and to adjust the size of the nip.
