DESCRIPTION:
BRIEF SUMMARY
This invention relates to apparatus for the detection of counterfeit documents and more particularly to apparatus for the detection of counterfeit banknotes or security papers.
BACKGROUND
Counterfeit documents are a serious problem for people who have to handle documents and supply goods or services in exchange for or as guaranteed by the documents. The most obvious examples are banknotes, bonds, share certificates and similar documents used in finance and banking, but problems also exist in other less spectacular situations such as forged gift tokens or tickets for a sporting occasion, concert or theatre. In all cases the chances of the counterfeit documents passing undetected are improved the more the person receiving the document is under pressure and therefore the less time the person has to notice or query a suspect document.
Moreover, as counterfeiting techniques have become more and more sophisticated it has become much harder for an untrained person to identify a counterfeit banknote quickly, particularly if the counterfeit note is only one of a number tendered simultaneously.
It is an object of the present invention to provide apparatus that can quickly and reliably detect a counterfeit document.
SUMMARY OF THE INVENTION
The present invention is an apparatus for detecting counterfeit documents comprising: a gate for receiving a document to be checked; a reservoir for a liquid that will react with, in a known way, a component of or an ingredient in the printing or composition of the document; a nib, within the gate to be charged with liquid from the reservoir and disposed to apply the liquid to the document received into the gate; and a seal around the nib to reduce loss of the liquid when there is no document in the gate .
BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a side elevation of an apparatus comprising a reservoir and a gate according to the present invention-before assembly, the gate being partially cut away to show internal detail;
FIG. 2 is a side elevation of the reservoir and gate of FIG. 1 when assembled, the gate again being partially cut away;
FIG. 3 is a front elevation of the assembly of FIG. 2;
FIG. 4 is a section on the line IV--IV of FIG. 3; and
FIG. 5 is an exploded view of the components of the gate which is again partially cut away.
DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
Referring now to the drawings, an apparatus according to the present invention for detecting counterfeit documents comprises a gate 10 and a reservoir 12 which lock together in use but which also allow the reservoir to be replaced when its contents are exhausted.
The reservoir 12 is circular in cross section and has a wall 14 extending from the closed front wall 16 of the reservoir to a lip 18 around the periphery of the top of the wall 14 at the rear of the reservoir. The lip 18 carries a plate 20 which seals the rear of the reservoir apart from a central hole surrounded by an axially outwardly extending collar 22. The lip 18 is also provided with a number of projections 23 (in this embodiment three such projections) which extend radially outwards, each projection extending counterclockwise from a ramp 24 to a top surface 26 in which is provided a groove 28.
On the interior of the front wall 16 of the reservoir 12 is provided an axially extending wall 32 which surrounds, supports and locates one end of a nib 34 of fibrous material, the other end of the nib 34 being located in and supported by the collar 22 round the hole in the plate 20 at the rear of the reservoir.
The gate 10 consists of two rectangular covers 40 and 42 which are secured together at their bottom flanges by fixing means such as rivets 44. The cover 40 has a central circular wall 46 on its rear surface and an inwardly directed flange 48 at the top of the wall. The flange 48 has three gaps 50 equally spaced around the circumference of the wall and extending outwardly from the inner periphery o
