Make the folding of each controlling switch；Transparent sealing plate is provided with below the control panel；The central controller and storage
Device is electrically connected with；Central controller, memory and micromachine are by storage battery power supply.
The beneficial effects of the invention are as follows：Under nature, each controlling switch is remained turned-off, and the colloid in development chamber will not be from
Flowed down in mozzle；When needing to reproduce fingerprint, by transparent sealing plate object fingerprint scanner；Central controller is read from memory
Print information, and by the line paddy position acquisition in fingerprint, central controller transmission signal will controlling switch corresponding with line paddy position
Open, while micromachine control piston plate extruding development chamber；Development chamber in colloid under compressing, from open mozzle in
Extrusion, because colloid has larger surface tension, now colloid forms tiny colloidal solution pearl in the port of mozzle, these
Colloidal solution pearl is combined into the line paddy pattern of fingerprint, and sharp contrast is formed with the mozzle being not switched on；When the light of fingerprint scanner
It is radiated at when on control panel, the mozzle for forming colloidal solution pearl is different to the reflectivity of light from the mozzle of closure, and then instead
Wrinkle ridge and the line paddy of fingerprint should be gone out, and then fingerprint is reproduced.
After using terminating, moved on micromachine control piston plate, the volume in development chamber becomes big, and colloid is from mozzle
Suck back；Controlling switch closure on central controller control mozzle；Now, this print development device returns to original state.
Structure of the invention is novel, and principle is unique, cheap for manufacturing cost, can realize the reproduction repeatedly of fingerprint, realizes remote
Apart from unlocked by fingerprint, operating efficiency is effectively improved.
Preferably, the mozzle is put together by relative symmetrical in semi arch piece concave surface of two elasticity；Semi arch
Piece is made by conductive material, connection of being insulated between semi arch piece and control panel；The central controller includes electronic emitter；Electronics
Transmitter after the semi arch piece contact electronics on mozzle, forms negative electrostatic to specific water conservancy diversion pipe inspection electronics；Two semicircles
The arc piece same sex is repelled each other, and is located remotely from each other, now mozzle " bifurcated ", and mozzle is opened；Colloid can ooze from the mozzle of bifurcated
Go out, and then colloidal solution pearl is formed in port；The structure eliminates the structure of controlling switch, greatly reduces manufacturing cost and manufacture
Difficulty, while improve the sensitivity of central controller.
Preferably, doped with colouring agent in the colloid；In order to improve the contrast of line paddy and wrinkle ridge pattern.
Preferably, the sealing plate is made by concavees lens；In order to pattern to be zoomed to the size with fingerprint equal proportion.
Preferably, being additionally provided with conduction brush below the control panel；In order to remove the negative electrical charge on mozzle,
Promote the closure of mozzle.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of this print development device one embodiment.
Specific embodiment
Embodiment
In the embodiment shown in fig. 1, this print development device includes housing, is provided with enclosure interior and referred to for storage
The memory 1 of line information；
The enclosure interior is provided with development chamber 2, colloid is filled with chamber 2 of developing, doped with coloring in the colloid
Agent；Colouring agent can effectively improve the contrast after pattern is formed；The top surface in development chamber 2 is slidingly sealed by piston plate 21, described
Piston plate 21 controls lifting by micromachine 3；
The bottom surface in development chamber 2 is sealed by control panel 4, and mozzle 41, each mozzle are shown in the first-class matrix of the control panel 4
41 conducting development chambers 2；The mozzle 41 is put together by relative symmetrical in the concave surface of semi arch piece 411 of two elasticity；Semicircle
Arc piece 411 is made by conductive material, connection of being insulated between semi arch piece 411 and control panel 4；In being additionally provided with the housing
Control device 5, the central controller 5 includes electronic emitter 51；Conduction brush 6 is additionally provided with the lower section of the control panel 4；Described
