Description
BILL ACCEFTOR
BACKGROUND OF THE IN'6~ENTION
1. Field of the Invention:
The present invention relates to bill <~.cceptors and, more particularly, to such a bill acceptor, which uses infrared light to fetch the image of inks of the bill to be examined and ultraviolet Light to scan fluorescent fibers of the bill, enabling the user to verify the authenticity of the bill accurately.
BACKGROUND OF THE IN'6~ENTION
1. Field of the Invention:
The present invention relates to bill <~.cceptors and, more particularly, to such a bill acceptor, which uses infrared light to fetch the image of inks of the bill to be examined and ultraviolet Light to scan fluorescent fibers of the bill, enabling the user to verify the authenticity of the bill accurately.
2. Description of the Related A~°t:
Fast development of high technology ,greatly improves our Ii~ing standard. However, there are people using high-tech products as tool to make illegal acts, for example, to paint counterfeit bills.
People usually verify the authenticit3~ of a banknote by touching or visual examination. It is difficult to verify the authenticity of a banknote in this way. There are bill acceptors which use ultraviolet light to scan the inks, hidden line, or embossed stamp. However, these bill acceptors cannot eliminate the interference of ambient light. The interference of ambient Light may cause a false determination. Further, because banknote issuing banks may frequently issue new banknotes with new counterfeit protection technology or arrangement to substitute for old banknotes.
Ordinary people may not have sufficient knowledge to verify the authenticity of newly issued banknotes.
In order to help people verify the authenticity of different bills, the inventor invented a bill acceptor entitled "Infrared light ink image display device". This design c~f bill acceptor is functional. However, there is still room for improvement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1~4, a bill acceptor is shown comprising of a housing 1 having installed therein a first light emitter 2, a second light emitter 3, an image sensor 4, and a display 5.
The housing 1 comprises a base 11 adapted to receive a banknote to be examined, a first power sensor 12 fastened pivotally with the base 11, a back 13 perpendicularly upwardly extended from the back side of the base I1, a top 14 horizontally forwardly extended from the top end of the back 13, a power adapter 15 provided at the back side of the back 13 and adapted to obtain the necessary electric. energy from city power supply, a second power sensor 16 pivotally fastened to the top 14, and two Iight-tight side panels 17 bilaterally connected between the tap 14 and the base 11.
The first light emitter 2 is installed in the top 14 of the housing 1, comprising an infrared light emitting head 21 aimed at the base 11 and adapted to emit infrared light the banknote 6 that is put on the base 11 for examination.
The second light emitter 3 is installed in the top 14 of the housing 1, comprising an infrared light emitting head 31 aimed at the base 11 and adapted to emit ultraviolet light onto the banknote
4 6 for visual examination.
The image sensor 4 is installed in the top 14 of the housing 1, comprising a charge-coupled lens 41.
The display 5 is installed in the back :l3 of the housing 1, comprising a display screen ~1.
When in use, the banknote 6 to be examined is put on the base 11 inside the housing 1 above the first power sensor 12. At this time, the first power sensor 12 is triggered to start the first light emitter 2, the image sensor 4, and the display S, thereby causing the first light emitter 2 to emit infrared light onto the banknote 6 and the image sensor 4 to pick up infrared light reflected by inks of the banknote 6 through the charge-coupled lens 41. When picked up reflected infrared light from the banknote 6, the image sensor 4 converts the light signal into image signal, enabling the image signal to be transmitted to the display 5 and then displayed on the display screen 51. Further, when the user lifting the banknote 6 from the base 11, the first light emitter 2 is turned off, and the image sensor 4 as well a.s the display ~ are turned off too. When the banknote 6 touching the second power sensor 16, the second light emitter 3 is started to emit ultraviolet light onto the banknote 6, thereby causing the fluorescent fibers in the banknote 6 to reflect ultraviolet light, and therefore the user can visually check the authenticity of the banknote 6. Further, s because the side panels 17 are light tight, they eliminate interference of external visible light, assuring high accuracy of the examination of the bill acceptor.
Deferring to FIG S. 5, 5A, 6, 6A, 7, and 7A, banknotes 6 issued by banks in different countries are printed with different combinations of inks. Every kind of ink has a particular wavelength.
When emitted infrared light onto a banknote 6, the inks of the banknote 6 absorb or reflect emitted infrared light, and the image sensor 4 receives reflected infrared light from the banknote 6 and then converts received light signal into image signal for verification.
A prototype of bill acceptor has been constructed with the features of FIGS. 1~7. The bill acceptor functions smoothly to provide ail of the features discussed earlier.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. For example, the housing of the bill acceptor can be made a table-top housing or mobile housing convenient for carrying by the user; battery power supply may be used instead of the power adapter to provide the bill acceptor with the necessary working voltage; switch means may be used to substitute for the power sensors. Further, the invention can be made in the form to verify the authenticity of banknotes, securities, stocks, passports, etc. Accordingly, the invention is not to be limited except as by the appended claims.
