Above-mentioned memory, control panel, operation panel are by storage battery power supply.
The beneficial effects of the invention are as follows：Under nature, the imaging liquid is in solid-state, the imaging liquid leaded light performance of solid-state
Difference；Raised in imaging liquid temperature and become liquid afterwards to a certain extent, the transparent color of imaging liquid of liquid, guide-lighting performance is strong；Fingerprint
Storage in memory, when needing to call, is recalled by control panel；Control panel, will be with wrinkle ridge according to the lines of fingerprint
The corresponding electrical heating post conducting in position, the heating surface of electrical heating post promotes imaging liquid to liquefy；Now, it is corresponding with wrinkle ridge position aobvious
As liquid is melted into Transparent color, the corresponding imaging liquid in line paddy position is in solid-like, and now the imaging liquid of diverse location is to the anti-of light
Penetrate intensity different, the power that the photosensitive sensors on fingerprint scanner are reflected according to light, you can carry out fingerprint recognition；When
After the end of scan, electrical heating post is stopped, and is gradually solidified after the imaging liquid radiating of liquid, restores to the original state.
State by changing imaging liquid of the invention, reproduces the concave convex texture of fingerprint, and then realize the reproduction of fingerprint；Structure
It is novel, unique, it is with low cost, when fingerprint owner cannot be in the action, it is also possible to unlocked under its mandate, effectively improve work
Efficiency, while the secret of equipment, security will not be reduced.
Preferably, being provided with scaling mirror in the bottom in the imaging chamber；In order to the image contracting presented in chamber will be imaged
It is small, and then improve the precision of images.
Preferably, being provided with the suction room connected with the imaging chamber on the housing, set in the suction room
Suction plate is equipped with, the suction plate is tightly connected with suction room by screw thread；The structure can will image the imaging of intraluminal fluid
Liquid is extracted out, improves the light contrast in imaging chamber, so that the phenomenon chamber apparent, pattern of imaging is distincter.
Preferably, the imaging liquid has thermoplastic material to make；This material can effective reduces cost, while have compared with
Good durability.
Preferably, adding colouring agent in the thermoplastic material；In order to improve extinction, the reflecting power of imaging liquid,
And then lift the definition of imaging.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram that this fingerprint reproduces machine one embodiment.
Specific embodiment
Embodiment
In the embodiment shown in fig. 1, this fingerprint reproduction machine includes housing, and enclosure interior is provided with for storing fingerprint
The memory 1 of information, what is be connected with memory 1 be additionally provided with control panel 2, and the parallel beneath of control panel 2 is provided with operation
Plate 3, electrical heating post 31 is placed with the first-class matrix of the operation panel 3 row, and the heating of electrical heating post 31 faces down；In the control
The lower surface of plate 2 is provided with spray point 21, and the spray point 21 and electrical heating post 31 are matched just pair and be electrically connected with one by one；
It is close to operation panel 3 and is provided with imaging chamber 4, imaging liquid is filled with the imaging chamber 4, the imaging liquid is by thermoplastic material
Make, can be polyethylene, polyarylate；Colouring agent is added in the thermoplastic material；It is provided with the bottom in the imaging chamber 4
Scaling mirror 5；The suction room 6 connected with the imaging chamber 4 is installed on the housing, is provided with the suction room 6 and taken out
Suction disc 61, the suction plate 61 is tightly connected with suction room 6 by screw thread；Above-mentioned memory 1, control panel 2, operation panel 3 are by storing
Battery 7 is powered.
Under nature, the imaging liquid is in solid-state, the imaging liquid leaded light poor performance of solid-state；It is increased in imaging liquid temperature
Become liquid afterwards to a certain degree, the transparent color of imaging liquid of liquid, guide-lighting performance is strong；Fingerprint is stored in memory 1, is being needed
When calling, recalled by control panel 2；Control panel 2, will electrical heating post 31 corresponding with wrinkle ridge position according to the lines of fingerprint
Conducting, the heating surface of electrical heating post 31 promotes imaging liquid to liquefy；Now, imaging liquid corresponding with wrinkle ridge position is melted into transparent
Color, the corresponding imaging liquid in line paddy position is in solid-like, and now the imaging liquid of diverse location is different to the reflected intensity of light, fingerprint
The power that photosensitive sensors on scanner are reflected according to light, you can carry out fingerprint recognition；After the end of scan, electricity adds
Plume 31 is stopped, and is gradually solidified after the imaging liquid radiating of liquid, restores to the original state.
In the present embodiment, in order to reduce the scaled fine degree requirement of electrical heating post 31, the finger that can be deposited in memory 1
After line information is amplified at double, then corresponding electrical heating post 31 is turned on by control panel 2, the pattern for now being obtained in video boards is amplification
Fingerprint afterwards, pattern passes through the diminution of scaling mirror 5, you can realize the equal proportion output of finger print information；The scaling structure of mirror 5 can have
Effect reduces the machining accuracy of operation panel 3, and then effectively reduces cost, while ensure that the readability of fingerprint.
Additionally, in the present embodiment, the rotatable suction plate 61 while imaging liquid liquefies, so as to by liquefied imaging liquid
Aspirate, as liquefied imaging liquid flows out, the imaging liquid thickness for imaging the internal solid of chamber 4 is different, and fingerprint now reproduces effect
Fruit becomes apparent from；After using terminating, suction plate 61 is reversely rotated, you can be injected back into imaging liquid again.
Colouring agent is added in the present invention in imaging liquid, the light guide effect of imaging liquid, Jin Ergeng can be further improved
Scanner is conducive to recognize fingerprint.
State by changing imaging liquid of the invention, reproduces the concave convex texture of fingerprint, and then realize the reproduction of fingerprint；Structure
