Abstract
The total reflection type fingerprint identifying device includes one main body, one light source, one connector and one sensor. The main body has one structural plane, one first reflecting area and one transparent area; the light beam the light source emits passes through the transparent area in the main body before irradiating the finger on the structural plane, the connector has one second reflecting area; and the sensor is set on the connector. Between the main body and the connector, one black diaphragm with opaque membrane and hole for the set light beam to pass, while filters out stray light. The fingerprint identifying device has high contrast and low noise, small size, simple making process and low cost.
Description
Technical field
The relevant a kind of fingeprint distinguisher of the present invention, particularly relevant a kind of full reflection fingerprint identifier.
Background technology
Biological identification is to carry out identification at the exclusive physiological characteristic of the mankind, sees through identification program and confirms true identity, and is through development for a long time, the most ripe with the development of identification of fingerprint at present.
The mode of identity identifications such as traditional password and IC Card, there is the inconvenience that needs storage or carry in the capital, and easy crack or situation such as be stolen, the characteristics of reviewing identification of fingerprint are that it does not need human body memory itself, also do not have the worry that must carry, the therefore problem that need not worry and be stolen is more because it possesses unique characteristic, promoted the security and the Reliability of identification, this also be traditional password and IC Card can be gradually by reason that identification of fingerprint replaced.At present the fingeprint distinguisher volume that uses is big, is inconvenient to be equipped on the petite product of volume, and fingeprint distinguisher costs an arm and a leg, so purpose of the present invention is promptly at the device of proposition one head it off.
Summary of the invention
Fundamental purpose of the present invention is that a kind of full reflection fingerprint identifier is being provided, when making its picking up fingerprint image, to reach high to low noise effect when.
Another object of the present invention is to provide a volume the little and high fingeprint distinguisher of fiduciary level, make it be applied to the petite product of volume.
A further object of the present invention is that processing procedure is simple, can reduce cost, and makes it have more competitive power.
According to the present invention, a kind of full reflection fingerprint identifier comprises a body, one light source, one conjugant and a sensor, body has the face structure, first echo area and photic zone, the face structure is in order to be placed on it finger, the light that light source produced is radiated at the structural finger of the face of being positioned over through the photic zone of body, make the light of finger print reflection be passed to first echo area, conjugant is provided with second echo area, conjugant and body link together, the junction is provided with an aperture, and at the conjugant end sensor is set,, makes sensor sense the finger print imaging in order to receive the light that transmit second echo area.

Embodiment
The invention relates to a kind of full reflection fingerprint identifier, it is provided with the design of two sides concave mirror, by the effect of concave mirror focus and reflection, prolongs optical path thus and can dwindle mechanism size, to reach the effect of identification of fingerprint.
As shown in Figure 1, it is a structural representation of the present invention, a kind of full reflection fingerprint identifier comprises a light source 4, one body 6, one conjugant 8 and a sensor 10, body 6 has one side structure 11, one first echo area 12 and photic zone 13, face structure 11 is a transparent material, it can be glass or light transmission plastic material, in order to place finger, the light that light source 4 produces via DIFFUSION TREATMENT after and form even light, it is radiated at the finger that is positioned on the face structure 11, conjugant 8 has another second echo area 14 again, and conjugant 8 is an annexation with body 6, both junctions are provided with aperture 16, and conjugant 8 one ends are provided with sensor 10.
Wherein, aperture 16 is the light tight poroid rete for black coating or blacking; Second echo area 14 of first echo area 12 of body 6 and conjugant 8 is a concave mirror, and both first, second echo areas are constituted by reflective metal coating.
Light path guiding of the present invention, produce uniform light by light source 4, its photic zone 13 through body is radiated at the finger that is positioned on the face structure 11, finger on the face structure 11 has different reflection rays because of the fingerprint lines is concavo-convex, finger reflection ray on the face structure 11 reflexes to first echo area 12 of body 6, first echo area 12 is with light focusing, and the light after will focusing on reflects away again, and the light that is reflected by first echo area 12 will be by an aperture 16, aperture 16 is the light tight poroid rete of black coating or blacking, the light that can allow first echo area 12 reflect, reflex to second echo area 14 of conjugant 8 according to light path, second echo area 14 is the light focusing that receives, and the light after will focusing on reflexes to sensor 10 again, and sensor 10 can sense the light signal of representing the finger print lines.Wherein, the aperture 16 of this body and this conjugant junction, it is the light tight poroid chemical material rete of a kind of black coating or blacking.The aperture 16 of this body 6 and this conjugant 8 junctions also can be the optical fiber material, and it can allow light walk according to light path, simultaneously unwanted parasitic light is stopped to eliminate veiling glare.
Comprehensive the above, the present invention provides a kind of full reflection fingerprint identifier, when the light of its light source shines fingerprint, different reflections can be arranged because of the fingerprint lines is concavo-convex, form bright dark grey-tone image, and fingeprint distinguisher has the design of two sides concave mirror, via first concave mirror focus and reflection ray, reflection ray is via aperture, aperture allows the light of representing the finger print lines pass through and the elimination veiling glare, eliminate light behind the veiling glare again via second concave mirror focus and reflex to sensor, sensor is again with the comparison of the previous fingerprint lines in resulting fingerprint lines of sensing and the data bank, reaching user's identity identification, so, the invention provides and a kind ofly have highly, make the user when operation, can obtain identity identification more accurately low noise fingeprint distinguisher when.
Please referring again to shown in Fig. 2 A, wherein visible and face structure 11 shown in the present is to present a state that tilts; Please referring to shown in Fig. 2 B, second echo area 14 is wherein directly removed, and sensor 10 is to be seated in the catoptrical position that can receive by first echo area 12; Be thickness then shown in Fig. 2 C, and present a strip, so the user needs just the fingerprint of finger comprehensively to be given being received by this sensor after the moving before and after the finger with a W for this face structure 11.
The above, for the present invention with reference to its preferred embodiment, and represent especially and illustrate that the personage who only has the knack of this skill will be appreciated that the various changes that reach in form on the details, all can not deviate from spirit of the present invention and claim scope.
