BACKGROUND OF THE INVENTION
1. Field of the Invention:
[0001] The present invention relates to bill acceptor technology and more particularly,
to a bill acceptor with bill passage anti-light pollution arrangement, which has privacy
filters installed in the light path of the bill-receiving unit thereof to reduce light
pollution, avoiding errors and faults and enhancing detection accuracy and reliability.
2. Description of the Related Art:
[0002] Following fast development of modern technology, convenience and rapidness have become
important demands in our modern daily life. Nowadays, different automatic vending
machines, card dispensers, auto teller machines, ticket machines and bill exchange
machines are used everywhere to sell different products and/or to provide different
services without serviceman. These machines are highly appreciated for the advantage
of saving much labor and bringing convenience to people.
[0003] Further, commercial automatic vending machines, auto teller machines and other consumer
systems may be equipped with a bill acceptor for receiving paper money. To avoid direct
loss due to counterfeiting and to avoid inadvertently passing counterfeit valuable
papers to consumers, a bill acceptor has recognition means to recognize the authenticity
of a valuable paper before receiving it. However, the bill passage of a bill acceptor
is specifically designed for a particular valuable paper of one specific width. Because
different valuable papers issued from different countries have different sizes (length,
width and thickness) and different anti-counterfeit characteristics at different locations.
A valuable paper that is inserted into a bill acceptor must be kept in accurate alignment
with the recognition device so that the recognition device can accurate recognize
the anti-counterfeit characteristics. If a valuable paper is inserted into a bill
acceptor in an offset manner, the recognition device of the bill acceptor may reject
the valuable paper due to a recognition error. In this case, the user must insert
the valuable paper again, causing inconvenience.
[0004] Further, during the operation of a recognition device of a bill acceptor to validate
the authenticity of an inserted valuable paper, a light emitter (for example, light-emitting
diode) of the recognition device emits light through a lens set and the inserted valuable
paper toward a light sensor. The light sensor determines the authenticity of the valuable
paper by measuring the energy of the light that passes through the inserted valuable
paper. Subject to the anti-counterfeit characteristics. (watermark, seal, hidden barcode
or laser tag) and material thickness, the authenticity and face value of the inserted
valuable paper can be accurately validated. Bill acceptors of the above mentioned
kind are, for instance, known from document
WO 96/23282 A1.
[0005] However, during validation operation of a recognition device of a bill acceptor,
sunlight or external luminous light or flashing light may pass through the bill slot
of the face panel into the internal bill passage of the bill acceptor to fall upon
the dust cover and the lens set of the recognition device to interfere with the light
being emitted by the light emitter toward the light sensor, resulting in a false detection
or detection error. The dust cover has wear-resistant, dustproof and anti-stain characteristics,
but it cannot filtrate external light rays to eliminate light pollution. When a light
pollution occurs, the validation accuracy will be affected. If an inserted valuable
paper cannot be validated and is rejected, the user shall have to insert the valuable
paper into the bill slot again, causing inconvenience.
[0006] Therefore, it is desirable to provide a bill acceptor that filtrates light pollution,
avoiding errors and faults.
SUMMARY OF THE INVENTION
[0007] The present invention has been accomplished under the circumstances in view. It is
therefore one object of the present invention to provide a bill acceptor with bill
passage anti-light pollution arrangement, which reduces light pollution, avoids errors
and faults, and enhances detection accuracy and reliability. To achieve this and other
objects of the present invention, a bill acceptor comprises a housing defining a bill
slot in a face panel thereof for the insertion of a bill, a bill-receiving unit accommodated
in the housing, and at least one privacy filter mounted in the bill-receiving unit
to prevent light pollution. The bill-receiving unit comprises a holder base defining
therein a bill passage in communication with the bill slot, a control module, a transmission
mechanism controllable by the control module to transfer an inserted bill, and a recognition
circuit assembly mounted in opposing top and bottom sides of the bill passage. The
recognition circuit assembly comprises a sampling and validating module consisting
of a plurality of light emitters and light sensors and controllable by the control
module to validate the authenticity and face value of an inserted bill. The at least
one privacy filter is mounted in a light path in the bill-receiving unit between the
bill passage and the light sensors to filtrate external light sources and to let the
light emitted by the light emitters pass toward the light sensors. According to the
invention, the privacy filter is a multilayer filter made using blind ultra-fine (micro-louver)
optical technology, wherein the privacy filter decreases the angle of the light path
in the bill passage, allowing only the light emitted by the light emitters to pass
through the bill passage at 90° angle or 60°±5° angle.
[0008] Further, the holder base of the bill-receiving unit comprises at least one light
transmissive portion disposed around the bill passage corresponding to the recognition
circuit assembly, a privacy filter locating groove extending around each light transmissive
portion, and a dust cover mounted in each privacy filter locating groove to hold one
respective privacy filter in each privacy filter locating groove. The privacy filter
is made using blind ultra-fine (micro louver) optical technology, and designed to
control reflection of light and to reduce glare. The privacy filter decreases the
angle of the light path in the bill passage, allowing only the light emitted by the
light emitters to pass through the bill passage toward the light sensors. Further,
the privacy filter with the respective dust cover can be made in any of a variety
of shapes and sizes subject to requirements without affecting the original dust protection
function of the dust cover.
[0009] Further, the holder base of the bill-receiving unit comprises at least one light
transmissive portion disposed around the bill passage corresponding to the recognition
circuit assembly, a privacy filter locating groove extending around each light transmissive
portion, and a dust cover mounted in the privacy filter locating groove to hold one
respective privacy filter in the at least one light transmissive portion. Further,
the control module of the bill-receiving unit comprises two circuit boards respectively
mounted in the holder base at opposing top and bottom sides of the bill passage, a
plurality of sensors installed in the circuit boards and adapted to sense the insertion
of a bill into the bill slot, a bearing shell mounted at each circuit board over the
sensors at the respective circuit board. The bearing shell comprises a privacy filter
locating groove accommodating at least one privacy filter, and a plurality of retaining
protrusions projecting into the privacy filter locating groove to hold at least one
privacy filter in the privacy filter locating groove. The privacy filter at the bearing
shell filtrates external light rays that are not emitted by the light emitters, reducing
light pollution, avoiding errors and faults, and prolonging the lifespan of the bill
acceptor.

4, the light emitters
241 emit light toward the lens sets
2431 in the through holes
2430 of the surrounding lens holders
243. At this time, the emitted light goes through the privacy filter
3 in the proximal dust cover
214, then the bill passage
20 and the bill
4, and then the privacy filter
3 in the distal dust cover
214 and then the lens sets
2431 in the through holes
2430 of the distal lens holders
243, and then falls upon the light sensors
242. Thus, the light sensors
242 can measure the energy of the incident light accurately, enabling the sampling and
validating module
240 to determine the authenticity and face value of the bill
4. The privacy filters
3 filtrate external sunlight, indoor luminous light and other full-spectrum light sources

221 over the respective sensors
222. The bearing shell
223 comprises a locating groove
2231, a plurality of through holes
2230 disposed in the locating groove
2231 corresponding to the sensors
222, a privacy filter
3 mounted in the locating groove
2231 and covered over the through holes
2230, and a plurality of retaining protrusions
2232 projecting into the locating groove
2231 and pressed on the privacy filter
3 to hold the privacy filter
3 in the locating groove
2231 positively. The privacy filter
3 filtrates external light rays that are not emitted by the light emitters
241, reducing light pollution, avoiding errors and faults, and prolonging the lifespan
of the bill acceptor.
