The currency validator for assessing bank notes, comprises a housing combining an inlet for receiving bank notes, a scanning path along which a received bank note is moved for assessment, and a drive arrangement associated with the scanning path for moving bank notes along the path. Scanners of different types are provided in removable modules whereby the scanners and the position thereof can be varied by replacing the module with a different module.

A drive linkage arrangement for a bill validator maintains driver rollers in synchronization as a bill is driven along a predetermined path for scanning thereof. The drive linkage is a parallelogram linkage with three nodes of the linkage driving drive rollers. The fourth node of the linkage is connected to the output of a gear box driven by a drive motor. The linkage is a cost effective reliable approach for distributing power of a single motor to the spaced drive rollers.

An acceptor for evaluating banknotes, or other paper forms of payment, that includes a replaceable sensor module which communicates in a standardized manner with a central processing unit. The sensor module includes a series of sensors and the signals of the sensors under go primary processing by the sensor module to correct for at least individual characteristics of the sensor module. The central processing unit can be updated if required for different applications. This arrangement adds consid...

The modular validator includes a frame body which acts as an intermediary for releasably securing and releasably electrically connecting a series of modular components. In particular, a releasable power interface cooperates with the frame body and a releasable validating head. The frame body allows each of the components to be separately removable and also provides electrical connection between the validator and a host device.

A banknote validator includes a banknote processing channel, a series of sensors located along the channel for scanning a banknote as it moves past the sensors, a central processing unit for controlling the operation of the validator and receiving and processing the signals from the sensors. A removable memory storage arrangement is insertable in a receiving location of the validator. The removable memory storage arrangement, when received in the receiving location, forms an electrical communica...

A banknote drive arrangement comprises a series of drive rollers which allow initial pivotting of a banknote during insertion of a banknote into a validator and also provide positive drive of a banknote out of the validator if the banknote is refused. The banknote drive arrangement includes at least two drive rollers which are always active and cooperate with respective passive rollers which are notched. The passive rollers lock against rotation in an infeed direction and freely rotate during ej...

A winding device for storing banknotes and dispensing banknotes previously stored comprises a driven winding drum adapted for rotation in a first direction to wind received banknotes on said drum and rotatable in a second opposite direction to dispense previously stored banknotes. The winding device includes tapes which are applied to both sides of each banknote as the banknote is wound on the drum, the tapes being staggered in relation to each other for allowing more space-efficient winding aro...

A device for processing accepted banknotes uses a processing junction with banknote accumulators arranged on either side thereof and a banknote vault or stacker located at one end of the processing junction. A banknote dispensing outlet is associated with the banknote accumulators for receiving previously accumulated banknotes which are dispensed through the outlet.

A combination banknote validator, banknote accumulator, banknote storage cassette and banknote dispenser is designed in a modular manner and the accumulator and banknote dispenser cooperate to additionally define part of a processing pathway therebetween. The banknotes can move in either direction along the processing pathway and preferably several accumulators are located along the pathway. The banknote dispenser is of a rotary design and stacks banknotes on the surface thereof and dispenses a ...

The banknote validator has an efficient drive path for moving banknotes through a validating head past a series of sensors. A series of sets of drive rollers are commonly connected by a gear train and efficiently move the banknote in a manner to avoid jamming of the banknote during feeding of the banknote and during ejection of the banknote from the inlet. The configuration of the banknote pathway, the mounting of the sensors, and the drive arrangement cooperate to provide a cost effective and e...
