Description

Multi-Functional Scanner and Scanning System

The present invention relates to a multi-function scanner capable of scanning various user authentication means including fingerprints, stamps (or stamps), as well as identification cards, and a scanning system for generating fingerprint images, stamp images and identification images using the multi-function scanners will be.

Various documents are being digitized. In particular, most of the documents submitted to banks are scanned and stored as digital images, or even written from scratch. Some countries, including the Republic of Korea, use stamps (or seals) as one of the means of personal authentication, while stamps have been recognized as a barrier to digitization. The stamp or stamp is to create a concavo-convex image by imprinting on the surface imprinted with a concave-convex shape and stamping it with paper or the like. Recently, a seal scanner has been developed that scans a seal, such as a fingerprint reader that generates a fingerprint image using a prism. The applicant has developed a technology related to the seal scanner and has completed patent registration (Registration Nos. 1542818 and 1594114 of Korea).

On the other hand, financial institutions acquire various personal information from users for various purposes, and the dojo is representative. In addition, we are scanning fingerprint images instead of stamps, and personal identification cards such as resident registration cards and driver's licenses. With the development of digital equipment, equipment for these individual purposes has been developed. On the desks of financial institution executives, there are a number of seal scanners that scan stamps, fingerprint scanners that scan user fingerprints, and scanners that are dedicated to ID cards that scan ID cards.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 to 3, the multifunctional scanner 100 according to an exemplary embodiment of the present invention includes a main body including a first scan unit 110, a second scan unit 130, and a scan control unit 151 ( 170), including a painting input unit 190 disposed on the upper surface of the main body 170, it is possible to generate an identification card image, a fingerprint image and an image of the uneven surface of the painting (hereinafter referred to as a 'paint image'). . The ID image is generated by the first scan unit 110, and the fingerprint image and the stamp image are generated by the second scan unit 130. Meanwhile, the multifunction scanner 100 may be connected to the user terminal 710 as described below, and generate a scanned image according to the 'scan command' provided by the user terminal 710.

The main body 170 includes a first scan unit 110, a second scan unit 130, a scan control unit 151 and a housing 171 accommodating them, and a painting input unit 190 is provided on the upper surface. The main body 170 illustrated in FIGS. 2 and 3 is a state in which the first scan unit 110 is horizontally disposed below and the second scan unit 130 is disposed on the first scan unit 110. Unlike FIGS. 2 and 3, the first scan unit 110 and the second scan unit 130 may be horizontally arranged.

FIG. 2 is a diagram showing an example of scanning the identification card 10 or generating a fingerprint image, and FIG. 3 is a diagram showing an example of generating a stamp image by scanning the stamp 20. In front of the body 170 of FIGS. 2 and 3, an inlet 111 for inserting the ID 10 into the first scan unit 110 is provided, and an elastic pad 131 for inputting a fingerprint on the upper surface is disposed And, there is provided with a cover-shaped coating input unit 190 thereon. Since the elastic pad 131 is located on the open upper surface of the second scan unit 130, the first scan unit 110 is located at the bottom and the second scan unit 130 is located thereon. The painting input unit 190 is disposed on the upper portion of the elastic pad 131, but as shown in FIG. 2, the fingerprint must be input directly to the elastic pad 131 of the second scan unit 130, so that the painting input unit 190 is input while entering the fingerprint. Is moved from the top of the elastic pad 131 to another place.

First scan unit

The first scan unit 110 scans the user's ID card 10 under the control of the scan control unit 151 to generate an ID card image. The scanning method of the first scan unit 110 may be any.

In general, a widely used method is a method using a contact image sensor (CIS: Contact Image Sensor) (not shown), and the first scan unit 110 of FIG. 1 uses two contact image sensors to input the inlet 111 It is possible to scan both sides of the ID card 10 is inserted at a time. Here, the two contact image sensors are arranged to face each other on the upper / lower or both sides with the axis of the entry direction entering the inlet 111 to scan both sides of the identification card 10 at a time. The first scan unit 110 may include two infrared contact image sensors in which the color CIS and the infrared light emitting unit / receiving unit are formed as a single module.

The first scan unit 110 may store the ID image generated by scanning in an internal memory (not shown), or provide it to the user terminal 710 described below.

2nd scan unit

The second scan unit 130 includes a transparent elastic pad 131 disposed on an open upper surface and optically generates a pattern image of a pattern (fingerprint or uneven surface of a fingerprint) input to the elastic pad 131. The second scan unit 130 may generate a pattern image (fingerprint image or stamp image) according to the pattern type and input method, and may store the generated fingerprint image or stamp image in internal memory, as described below. It can be provided to the user terminal 710. The second scan unit 130 starts a scan operation such as turning on an internal light source under the control of the scan control unit 151.

<First embodiment of the second scan unit>

The second scanning unit 130 may be any optical scanner. For example, the second scan unit 130 may apply a conventional transmissive (or scattering) or reflective (or absorbing) fingerprint sensor that is widely used for fingerprint recognition. The second scan unit 400 shown in FIGS. 4 and 5 includes a light refractor 401 receiving a pattern image, and a light source 405 irradiating light toward the light refractor 401; It includes an image sensor 403 for generating a pattern image with the image emitted from the photorefracter 401. The elastic pad 131 is attached on the pattern input surface of the optical refractor 401. The light for image acquisition emitted from the light source 405 and incident into the photorefractor 401 is reflected, refracted or scattered by the photorefracter 401 to generate a patterned image. It can be triangular like Prism of 4, or rectangular like trapezoid, trapezoid, isosceles triangle.

Referring to the fingerprint image generation of FIG. 4, the user fingerprint directly contacts the transparent elastic pad 131. In the case of the absorption type, since light emitted from the light source 405 passes through the photorefractor 401 and enters the outer surface of the elastic pad 131 at an angle greater than a critical angle, reflection occurs in the bone of the fingerprint. Therefore, the pattern image becomes an image with bright valleys and dark ridges. In the case of the scattering type, the light source 405 may be provided at a different position from the light sources 405 of FIGS. 4 and 5, and the light for image acquisition is an elastic pad 131 at an angle less than a right angle or a critical angle for total reflection. It is incident on the outer surface. Therefore, scattering occurs in the ridge of the fingerprint, and the bone is refracted without total reflection, so that the uneven part is bright and the rest is dark.

When the pattern of the uneven surface 20a of the painting 20 is input, the operation in the second scan unit 400 is the same as the process of acquiring a fingerprint image. However, instead of the fingerprint directly contacting the elastic pad 131, the coating 20 is different from the elastic pad 131 intermittently using the elastic film 191. Referring to FIG. 5, in order to input the painting 20, the painting input unit 190 is disposed on the upper surface of the elastic pad 131. As a result, the elastic film 191 is disposed in parallel with each other while forming the space portion 190a between the elastic pad 131. When the user presses the elastic film 191 with the uneven surface 20a of the coating 20, the elastic film 191 in a state pulled with a constant tension covers the uneven surface 20a as it is. It is as if the uneven surface 20a of the coating 20 is covered with a thin film. As a result, the elastic pad 131 is pressed in the shape of the uneven surface 20a by the elastic film 191. Subsequently, light is emitted from the light source 405 to generate a painted image of the pattern of the uneven surface 20a contacting the elastic pad 131.

<Second embodiment of the second scan unit>

In another way, the second scan unit 600 illustrated in FIG. 6 has a closed box shape and an elastic pad 131 is disposed on the opened upper surface. The second scan unit 600 is a light source 601 for irradiating light toward the lower surface of the elastic pad 131, and a camera that directly captures the elastic pad 131 under the elastic pad 131 to obtain a pattern image Includes part 610. The camera unit 610 may include a lens unit 611 and an image sensor 613.

The light source 601 may be positioned anywhere under the elastic pad 131 to the elastic pad 131 to be irradiated with light. However, it is necessary to adjust the light emitted from the light source 601 so that it does not directly enter the camera unit 610. In the case of inputting a fingerprint, the user's fingerprint is directly input to the elastic pad 131. The light irradiated from the light source 601 to the elastic pad 131 illuminates the fingerprint in contact with the elastic pad 131, and the camera unit 610 directly photographs the elastic pad 131 to generate a fingerprint image. When the painting is input, the light irradiated from the light source 601 to the elastic pad 131 is reflected and refracted between the elastic pad 131 and the elastic film 191 or between the elastic pad 131 and the space 190a. Alternatively, while being scattered, it is imaged as a pattern of the uneven surface 20a of the coating 20 stamped on the elastic film 191, and is incident into the internal space through the elastic pad 131 and is formed on the camera unit 610.

Referring to FIG. 3, an upper support portion 630 made of a transparent material is disposed on an upper surface of the opened housing 171 to support all or part of the elastic pad 131. The upper support portion 630 is sufficient if it is a flat panel made of a thin and transparent material so that the image incident through the elastic pad 131 is not distorted. The upper support portion 630 may be made of thin transparent acrylic or synthetic resin.

On the other hand, if the elastic pad 131 can support the stamping of the coating 20 by having a certain hardness, the upper support 630 is not necessary.

<Elastic pad>

The elastic pad 131 disposed on the upper surface of the second scan unit 130 can directly receive a fingerprint and at the same time facilitate the pattern input of the paint 20, which is a rigid body, and the uneven pattern of the fingerprint and the paint 20 Becomes the 'pattern input surface' that is finally input. In particular, the elastic pad 131 is for easily inputting the uneven pattern of the coating 20, and is applied to the same purpose as the elastic pad of Korean Patent Registration No. 1542818 or 1594114. For example, even if the coating 20 is not indented in the vertical direction but is inclined within a certain range and indented, there is no problem in generating a pattern image since the elastic pad 131 is not indented into the uneven pattern of the coating 20. On a hard and flat pattern input surface, such as a conventional seal scanner or fingerprint reader, the part that is not in contact with the pattern input surface cannot be generated even if the painting is slightly inclined.

Therefore, if the stamping direction of the hard coating 20 is roughly perpendicular, the elastic pad 131 is a transparent material having a weak level of elasticity so that the entire uneven portion of the uneven surface 20a can be completely adhered to the elastic pad 131. It is possible. Therefore, if the 'elasticity' here is literally deformed and then recovered, the degree of elasticity may be weak. For example, silicone or synthetic resin may be used as the material of the elastic pad 131.

In the case of generating a fingerprint image, it is preferable that the elasticity of the elastic pad 131 is not large, even though it is necessary to directly input the fingerprint into the elastic pad 131. If the elastic pad 131 is elastic and sufficiently hard, there is no problem in inputting the fingerprint.

The elastic pad 131 is preferably supported by the optical refractor 401 of FIG. 4 or the upper support 630 of FIG. 6. In particular, when the elastic pad 131 is disposed on the upper surface of the optical refractor 401, forming an adhesive layer by a separate adhesive between the elastic pad 131 and the optical refractor 401 may cause the optical path to be distorted. This is not desirable.

Painting input part

The painting input unit 190 accommodates the elastic film 191. As briefly described above, the elastic film 191 of the paint input unit 190 is configured to generate a paint image together with the elastic pad 131.

The painting input unit 190 accommodates the elastic film 191, and is moved to another place while entering a fingerprint, and has a dynamic structure to be located on the upper surface of the elastic pad 131 when entering the painting. The dynamic structure may be, for example, a hinge 193 provided on one side of the painting input unit 190 as shown in FIG. 3, a linear sliding structure or a vertical axis moving between the upper surface of the elastic pad 131 and another point. It may be a rotating structure that rotates around the center.

The elastic film 191 is the same as the elastic film of Korean Patent No. 1542818 or 1594114 and is applied for the same purpose. The elastic film 191 may be transparent, translucent, or opaque. However, in the case of the second scan unit 130 of FIG. 3, the elastic film 191 is preferably opaque.

In order to input the coating, the elastic film 191 is disposed on the upper surface of the elastic pad 131 spaced apart from the elastic pad 131 at a predetermined distance and arranged in parallel. Therefore, a space portion 190a is provided between the elastic pad 131 and the elastic film 191. The coating 20 is stamped on the elastic film 191, and the elastic pad 131 receives an uneven pattern through the elastic film 191 without receiving an uneven pattern directly from the painting 20.

The elastic film 191 is a surface where the uneven surface 20a of the coating 20 directly contacts. When repeatedly stamped with the uneven surface 20a contaminated by ink or ink, the elastic film 191 must be contaminated, but in the present invention, the elastic pad 131 is not affected by the contamination of the elastic film 191 Does not. This is because, even if the elastic film 191 is already contaminated, the elastic film 191 replaces the painting 20 to seal the elastic pad 131 in the uneven shape of the painting 20. When the elastic film 191 is implemented as an opaque material in the second scan unit 600 of FIG. 6, the elastic film 191 may be contaminated.

The elastic film 191 is a sufficiently thin film, and it is sufficient if the shape of the uneven surface 20a of the coating 20 can be input to the elastic pad 131 without distortion. For example, it is thin, such as silicone, natural rubber, or synthetic resin. Membranes can be used. For the pattern input, the elastic film 1130 should be able to press the elastic pad 131 in the shape of the uneven surface 20a by being pulled with a constant tension at least during the imprinting process.

Scan control unit

The scan control unit 151 receives a scan command provided from an external device such as the user terminal 710 described below, and one of the first scan unit 110 and the second scan unit 130 is received according to the scan command. Control it to work. Usually, the first scan unit 110 and the second scan unit 130 are preferably in a standby mode to reduce unnecessary power consumption. During the standby mode, the light sources 405 and 601 are turned off, and the image sensor 403 and the camera unit 610 may also operate in the standby mode to reduce power consumption.

The scan control unit 151 may provide an external device with one of an ID image generated by the first scan unit 110 and a fingerprint image or a stamp image generated by the second scan unit 130 according to the scan command. The scan command may be divided into a scan command for the first scan unit 110 and a scan command for the second scan unit 130.

The present invention also extends to a scanning system with a multifunctional scanner. Referring to FIG. 7, the scanning system 700 of the present invention includes a multifunction scanner 100 and a user terminal 710, and the multifunction scanner 100 and the user terminal 710 are mutually connected through a wired or wireless communication interface.

The input unit 713 may be a keyboard, a button, or a touch pad installed together with a display unit (not shown).

The terminal control unit 715 may perform various functions. First, the terminal control unit 715 provides a scan command input to the input unit 713 to the multifunction scanner 100, and requests to generate one selected from an ID card image, a fingerprint image, and a stamp image.

The terminal control unit 715 may perform an identification card scan and compare whether the printed fingerprint image and the fingerprint image scanned by the second scan unit 130 are the same fingerprint, if there is a fingerprint image in the provided identification card. There are fingerprint images printed on some identification cards, such as resident registration cards. The terminal control unit 715 extracts the feature points by extracting the printed fingerprint image when there is a printed fingerprint image from the ID image provided by the multifunction scanner 100. Thereafter, the terminal control unit 715 may extract a feature point from the fingerprint image generated and provided by the second scan unit 130 and then determine whether the fingerprint is the same as the fingerprint image extracted from the identification card.

According to another embodiment, the terminal control unit 715 may extract and recognize user information from the ID image provided by the first scan unit 110 according to a scan command. If, in a series of processes, the second scanning unit 130 also generates and provides a fingerprint image and / or a stamp image, the terminal control unit 715 can connect the fingerprint image and / or the stamp image to user information and store it. have.
