TITLE

FIELD OF INVENTION

The invention relates to an apparatus and a method for maintaining surface smoothness of a document during high speed processing.

    BACKGROUND 10

Automated, high- volume currency processing is an important technical field affecting numerous aspects of the distribution, collection, and accounting of paper currency. Currency processing presents unique labor task issues that are intertwined with security considerations. Currency processing requires numerous individual tasks, for example: the collection of single notes by a cashier or bank

teller, the accounting of individual commercial deposits or bank teller pay-in accounts, the assimilation and shipment of individual deposits or accounts to a central processing facility, the handling and accounting of a currency shipment after it arrives at a processing facility, and the processing of individual accounts through automated processing machines. Any step in the process that can be

20

automated, thereby eliminating the need for a human labor task, saves both the labor requirements for processing currency and increases the security of the

entire process. Security is increased when instituting automated processes by eliminating opportunities for theft, inadvertent loss, or mishandling of currency and increasing accounting accuracy.

A highly automated, high-volume processing system is essential to numerous

5

levels of currency distribution and collection networks. Several designs of high- volume processing machines are available in the prior art and used by such varied interests as national central banks, independent currency transporting companies, currency printing facilities, and individual banks. In general, currency processing machines utilize a conveyer system which transports individual notes

past a series of detectors.

One of the major challenges in high-volume banknote sorting and processing consists in detecting properties of the banknote, as for example images of the banknote in order determine their authenticity or fitness. In order to obtain these properties, the banknotes have to be flat during detection/sensing. However, if

15

the banknotes are held between conveyor belts, parts of the banknote are hidden and cannot be analyzed.

Various concepts have been developed in order to keep the banknotes flat without conveyor belts. In one of these concepts, the conveyor belts are omitted on one side while the banknote is sucked to the opposite conveyor or a plate. 20

This, however, allows only taking images from one side of the banknote.

EP 2 081 862 A2 discloses a banknote processing machine that relies on inertia or centrifugal forces for keeping the banknotes flat during inspection. A curved document guide is used to generate the inertia/centrifugal force. However, this solution requires too much space.
