Counterfeit document detector
US 3842281 A
Resumen
A housing has a structural portion which forms a light shield and another structural portion adjacent to the light shield which forms an easel suitable for supporting a document to be verified such as currency. An ultraviolet lamp is mounted behind the light shield such that the ultraviolet energy therefrom strikes the currency. Counterfeit currency is readily detected by virtue of a characteristic blue glow that it gives off.

Sokolski [57 ABSTRACT A housing has a structural portion which forms a light shield and another structural portion adjacent to the light shield which forms an easel suitable for supporting a document to be verified such as currency. An ultraviolet lamp is mounted behind the light shield such that the ultraviolet energy therefrom strikes the currency. Counterfeit currency is readily detected by virtue of a characteristic blue glow that it gives off.

4 Claims, 4 Drawing Figures COUNTERFEIT DOCUMENT DETECTOR This invention relates to a counterfeit document detector and more particularly to such a device utilizing ultraviolet light in identifying counterfeit currency.

The unwitting acceptance of counterfeit currency has been a problem for many years in view of the difficulty of any but the most expert in telling good money from bad. This is a particular problem in situations where a good deal of currency is rapidly passed, such as in super markets, department stores and banks, in view of the lack of time for the cashier or teller to examine the bills except in a very cursory fashion. Where bills are expertly counterfeited, they tend to pass as real except when examined by experts.

It has been found that most counterfeit currency has a chromamorphic response or color change when it is viewed in ultraviolet light such that it fluoresces with a bluish light glow. This is due to bleach or photochemicals used in the paper used for most counterfeit money. Genuine currency is printed on a special paper manu factured under strict government control which has no bleach or chemicals therein. Thus, genuine currency will not glow in the fashion just described when subjected to ultraviolet light.

, The device of this invention provides a simple, convenient device of economical construction to facilitate the examination of bills and other documents under ultraviolet light to verify their authenticity. The device of the invention is of compact construction and can be placed on a counter where it occupies a minimum of space. I

It is therefore an object of this invention to facilitate the detection of counterfeit currency and other counterfeit documents.

Another object of this invention is to provide a compact, inexpensive device for enabling the rapid and accurate checking of currency.

Other objects of the invention will become apparent as the description proceeds in connection with the accompanying drawings, of which:

FIG. 1 is a perspective view of one embodiment of the invention;

F IG. 2 is a cross-sectional view taken along the plane indicated by 22 in FIG. 1;

F lG. 3 is a cross-sectional view taken along the plane indicatedby 3-3 in FIG. 2; and

FIG. 4 is a cross-sectional view taken along the plane indicated by 4-4 in HQ 2.

Briefly described, the device of the invention comprises a housing with an ultraviolet lamp mounted therein and a switch and transformer forenabling the operation of such lamp from an AC power line. A portion of the casing is shaped to form a light shield for the ultraviolet lamp, this shield directing the light from the lamp towards another portion of the casing which forms an easel on which the currency to be examined can be placed. The easel portion of the casing provides a housing for a transformer for providing power to the lamp. A pair of removable end plates are provided to facilitate assembly of the device, one of these end plates having a lamp switch mounted therein. Currency and other documents can then be placed on the easel with the ultraviolet light directed thereagainst for rapid identification.

Referring now to the figures, the casing 11 has a light shield 12 formed along the front thereof. Supported in the casing behind light shield 12 in a pair of lamp sockets 14 is ultraviolet lamp 15. The upper portion 12a of light shield 12 wraps around lamp 15 so as to direct the light output thereof towards the face 17a of easel portion 17 of the casing. Power is provided for lamp 15 through power cord 18 which is connected to the AC power line. The AC voltage is stepped down to an appropriate value for the lamp by means of transformer 20 which is mounted in the easel portion of the casing. The lamp power is switched on and off by means of switch 22 mounted on end plate 25. End plate 25 is removably attached to the main body of the casing by means of screws 28, thus facilitating the removal of the plate to repair or replace the various parts. I

Easel portion 17 has a flat surface 17a which is slanted away from lamp l5 and extends from directly opposite the lamp to a line above the edge of shield portion 12a. The easel thus provides a convenient support for a bill 25 or other document to be examined. Easel portion 17 also has a wall 17b which slants away from surface 17a and forms the rear wall of the casing. The lower portion of such bill 25 is positioned directly opposite and in close proximity to the lamp in a location where the light emissions thereof are shielded by shield 12 while at the same time thesebottom bill portions can be readily viewed from above by an observer. Easel l7 and shield 12 can each be fabricated from single pieces of sheet metal bent to the desired configura-- tions, making for highly simple and economical construction.

As already noted, when avalid piece of currency 25 is exposed to the ultraviolet light, lamp 15, there is no glow or color change. A counterfeit bill, on the other hand, will glow with a bright blue fluorescent color.

The device ofthe invention thus provides a simple and economical means which can be mounted on'a smaller corner of the counter for checking the validity of currency. I v

While the device of the invention has been described and illustrated in detail, it is to be clearly understood that this is intended by way of illustration and example only, and is not to be taken by way of limitation, the spirit and scope of this invention being limited only by the terms of the following claims. a

I claim:

l. A device for checking the comprising:

a casing having a first portion thereof shaped to form a light shield, and a second portion thereof shaped to form an easel for supporting a document to be examined,

an ultraviolet lamp mounted in said casing adjacent to and behind said light shield, said light shield having a part thereof which wraps around said lamp,

validity of a document said easel portion extending at a slant angle from opposite said lamp away from the lamp to a line above the edge of the wrap-around part of said light shield, said light shield directing the light from said lamp towards said easel portion, and means for selectively energizing said ultraviolet lamp,

2. The device of claim 1 wherein said light shield extends along a front edge of said casing and said easel includes a flat, front portion positioned opposite said light shield and slanted away from said shield and the back portion which forms the rear wall of the casing.

3. The device of claim 1 and further including end plates removably attached to the opposite ends of said said transformer.
