Abstract
The utility model relates to an identification device, in particular to a fingerprint identification device. The utility model provides a fingerprint identification device provided with a fingerprint erasing device used for erasing the fingerprint at any time. The fingerprint identification device comprises a fixed plate, a fingerprint acquiring window arranged on the fixed plate and the finger erasing device arranged above the fingerprint acquiring window and fixed on the fixed plate. The fingerprint identification device remedies insufficiency of the traditional design, and avoids safety hidden troubles caused by residual fingerprint or copied fingerprint. Besides, the fingerprint identification device is simple and reasonable in design, and is suitable for batch production.
Description
Technical field
The utility model relates to a kind of recognition device, specifically, relates to a kind of machine fingerprint identification device.
Background technology
Fingerprint identification technology be with the most use in the present field of biological recognition, also be the most ripe a kind of biological identification technology.Press the difference of fingerprint collecting mode, finger print acquisition module is divided into optical profile type, semicoductor capacitor formula and RF-type; When being used for safety-security area, back two kinds of acquisition mode level of securitys are high, but finger is had relatively high expectations, to having impalpable defective as dirty finger, dried finger, the finger that wets, shallow texture fingerprint, the old user of finger; The optical profile type acquisition mode goes for the comparison rugged environment, finger there is not too harsh requirement, but can use the fingerprint recognition window in the traditional design, on this glass sheet, tend to residual user's fingerprint down, by shine these fingerprints with electric torch, or take the fingerprint to duplicate again just and can obtain false fingerprint, just can carry out the forgery of identity information with these residual fingerprints or false fingerprint then, have an opportunity to take advantage of, reduce the security of biological identification technology thereby bio-identification is become.
Summary of the invention
The utility model provides a kind of being provided with to wipe line device, the fingerprint identification device that can at any time fingerprint be wiped.
The technical scheme of fingerprint identification device of the present utility model is such, it comprises fixed head, fingerprint collecting window, and the fingerprint collecting window is arranged on the fixed head, and it also comprises the fingerprint erasing apparatus, the fingerprint erasing apparatus is arranged on the top of fingerprint collecting window, is fixed on the fixed head.
The fingerprint erasing apparatus comprises drive motor, transmission gear, the push pedal of wiping line, wipes the line brush, wipe the line brush and wipe the line push pedal and is connected, drive motor by driven wheel, wipe the line push pedal and drive and wipe line and brush.
Fingerprint identification device of the present utility model has following advantage:
The utility model is provided with the fingerprint erasing apparatus, the fingerprint erasing apparatus is arranged on the top of fingerprint window, be fixed on the fixed head, the fingerprint erasing apparatus comprises drive motor, transmission gear, the push pedal of wiping line, wipes the line brush, push pedal is connected wiping line brush with the wiping line, and drive motor is wiped line and brushed by driven wheel, wiping line push pedal driving.After the user used fingerprint reading device, motor will start like this, and driven wheel drive to be wiped line push pedal action, wiped the line push pedal and wipe the line brush to be connected, and the wiping line is brushed will be inswept before the fingerprint collecting window, and fingerprint is wiped.
Description of drawings
Fig. 1 is the structural representation of fingerprint identification device of the present utility model.
1-fixed head, 2-transmission gear, 3-drive motor, 4-wipe line push pedal, 5-fingerprint collecting window, 6-wiping line brush.
Embodiment
It comprises fixed head 1, fingerprint collecting window 5 fingerprint identification device of the present utility model, and fingerprint collecting window 5 is arranged on the fixed head 1, and it also comprises the fingerprint erasing apparatus, and the fingerprint erasing apparatus is arranged on the top of fingerprint collecting window 5, is fixed on the fixed head 1.The fingerprint erasing apparatus comprises drive motor 3, transmission gear 2, wipes line push pedal 4, wipes line brush 6, wipe line brush 6 and wipe line push pedal 4 to be connected, drive motor 3 by transmission gear 2, wipe line push pedal 4 and drive the wiping lines and brush 6.
The utility model has solved the deficiency of traditional design, provides a kind of having avoided to be replicated the potential safety hazard that produces because of residual fingerprint or fingerprint; This new structure simplicity of design is reasonable, is suitable for producing in batches.
