Abstract
The utility model relates to an improved laser counterfeit identifying device which is arranged on a paper money channel between the inlet and outlet of a counterfeit detector. The device comprises a projection type currency detecting platform, a laser light source fixed below the currency detecting platform, specific mark image probes fixed over the currency detecting platform and an identifying circuit. The improved laser counterfeit identifying device is characterized in that the laser light source is provided with a diffraction device along the emitting direction. The improved laser counterfeit identifying device has the beneficial effects that the improved laser counterfeit identifying device overcomes the defect of low accuracy of the laser counterfeit identifying device of existing counterfeit detector; with a grating lens, laser emitted by a laser emitter diffracts to form a linear detection area on the paper money detected; the paper money detected is moved to detect the whole laser-sensitive area, thereby greatly improving the detection accuracy and reducing the rate of misjudgment.
Description
Technical field
The utility model belongs to financial apparatus and makes the field, relates to a kind of improved laser false-identifying device, the false-identifying device of particularly in cash inspecting machine, using, utilize laser emission probe detection Renminbi laser anti-counterfeit information.
Background technology
Continuous development along with science and technology; It is also increasingly high that lawless person's Renminbi is copied technology; False tickets, counterfeit money can cause very big harm to society, and some anti-counterfeiting information that general Renminbi often adopts during fabrication, have been controlled by the offender such as means such as ink color, concavo-convex, magnetic; It is not enough to the identification of experience of true and false Renminbi to add the masses, has increased the difficulty of differentiating especially.In the Renminbi laser false-identifying device in the existing cash inspecting machine, the laser beam that laser probe sends is point-like, and its defective is: detected object is through laser emission probe the time; From dynamically, the zone of in fact being checked is a line segment, rather than the laser-sensitive district on the whole Renminbi; If the laser-sensitive district of detected object departs from the point-like laser beam; Just might detect less than, cause erroneous judgement, misjudgement phenomenon, the precision of whole device is reduced.
Summary of the invention
The utility model has designed a kind of improved laser false-identifying device in order to improve the precision that Renminbi laser false-identifying device is differentiated the Renminbi true money, improves the precision that detects effectively, has reduced False Rate.
The technical scheme that the utility model adopts is: a kind of improved laser false-identifying device; This device is arranged on the banknote path between the cash inspecting machine import and export; Comprise projection-type currency examine platform in the structure; And being fixed on the LASER Light Source of currency examine platform below and the specific marker image probe and the identification circuit thereof of top, key is: described LASER Light Source is provided with diffraction instrument along transmit direction.
The beneficial effect of the utility model is: the utility model has remedied the low deficiency of laser false-identifying device precision of existing cash inspecting machine; The laser that makes generating laser launch by the grating camera lens produces diffraction phenomena; On Renminbi to be detected, form linear surveyed area; Again Renminbi to be detected is moved and just can detect whole laser-sensitive district, improved the precision that detects greatly, reduced False Rate.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the LASER Light Source of grating belt camera lens in the utility model.
In the accompanying drawing, the 1st, currency examine platform, the 2nd, bar shaped light hole, the 3rd, LASER Light Source, the 4th, grating camera lens, the 6th, specific marker image probe.
Embodiment
A kind of improved laser false-identifying device; This device is arranged on the banknote path between the cash inspecting machine import and export; Comprise projection-type currency examine platform 1 in the structure; And be fixed on the LASER Light Source 3 of currency examine platform 1 below and the specific marker image probe 6 and the identification circuit thereof of top, importantly: described LASER Light Source 3 is provided with diffraction instrument along transmit direction.
On the emission port of the device of LASER Light Source 3, added grating camera lens 4.
The supporting light source that is provided with of grating camera lens on LASER Light Source 3 is apart from regulating device.
Combine the position of laser anti-false sign in the bank note that bar shaped light hole 2 is set on the currency examine platform 1.
Like this; To produce diffraction phenomena through narrow diffraction instrument by the laser that LASER Light Source 3 sends; Make and originally be radiated on the Renminbi to be detected through bar shaped unthreaded hole 2 for the light source of point-like changes linear laser beam into; Make laser beam can detect whole laser-sensitive district through moving Renminbi, improved the precision that detects greatly.
The quantity of described bar shaped light hole 2 is 1～2.
The quantity of described LASER Light Source 3 is 1～2.
The quantity of described specific marker image probe 6 is not less than 2.The whole device that is arranged so that of specific marker image probe 6 and identification circuit becomes a kind of robotization false-identifying device; Judge that and need not naked eyes specific marker image probe 6 sends a signal to identification circuit through the bright degree of laser on the perception Renminbi true money is made judgement.
In the specific implementation, bar shaped light hole 2 is set to two, and is symmetrically distributed in the both sides of Renminbi center line to be detected, and the number of LASER Light Source 3 is one, and the number of specific marker image probe 6 is two.The light beam that LASER Light Source 3 sends produces diffraction phenomena through grating camera lens 4; Can pass two bar shaped light holes 2 on the currency examine platform 1 simultaneously; Beat in the laser-sensitive district of Renminbi to be detected; Produce visible photoluminescence line, photoluminescence line is through 6 identifications of specific marker image probe, and specific marker image probe 6 is sent to identification circuit with photosensor signal and realizes robotization false distinguishing purpose.
