The present invention will be described in more detail below with reference to the drawings.

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

The 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 paint input unit 190 is provided on the upper surface thereof. In the main body 170 shown in FIGS. 2 and 3, a first scan unit 110 is disposed horizontally below and a 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 side by side.

FIG. 2 is a diagram illustrating an example of scanning an identification card 10 or generating a fingerprint image, and FIG. 3 is a diagram illustrating an example of generating a stamp image by scanning the stamp 20. In front of the main body 170 of FIGS. 2 and 3, an inlet 111 for inserting the identification card 10 into the first scanning unit 110 is provided, and an elastic pad 131 for inputting a fingerprint is disposed on the upper surface. And, a cover-shaped coating input unit 190 is provided thereon. Since the elastic pad 131 is located on the open upper surface of the second scanning unit 130, the first scanning unit 110 is located below and the second scanning unit 130 is located thereon. The seal input unit 190 is disposed above the elastic pad 131, but as shown in FIG. 2, the fingerprint input unit 190 must be directly inputted through the elastic pad 131 of the second scanning unit 130. 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. Any scanning method of the first scanning unit 110 may be used.

A generally widely used method is a method of using a contact image sensor (CIS) (not shown), and the first scanning unit 110 of FIG. 1 uses two contact image sensors to provide an inlet 111 Both sides of the ID card 10 inserted as can be scanned at once. Here, the two contact image sensors are arranged so as to face each other on the upper/lower side or both sides with an axis of the entrance direction entering the inlet 111 so that both sides of the identification card 10 can be scanned at once. The first scan unit 110 may include two infrared contact image sensors in which a color CIS and an infrared light emitting unit/receiving unit are formed as one module.

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

2nd scan section

The second scanning unit 130 includes a transparent elastic pad 131 disposed on an open upper surface and generates a pattern image of a pattern (fingerprint or uneven surface of a painting) input to the elastic pad 131 by an optical method. The second scanning unit 130 may generate a pattern image (fingerprint image or stamp image) according to the type and input method of the pattern, and may store the generated fingerprint image or stamp image in the internal memory, as described below. It can be provided to the user terminal 710. The second scan unit 130 initiates a scanning operation such as turning on an internal light source under the control of the scan controller 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 widely used for fingerprint recognition. The second scan unit 400 illustrated in FIGS. 4 and 5 includes a photorefractive device 401 receiving a pattern image, and a light source 405 that irradiates light toward the photorefractive device 401; It includes an image sensor 403 that generates a pattern image from an image emitted from the photorefractor 401. The elastic pad 131 is attached on the pattern input surface of the optical refractor 401. The image acquisition light emitted from the light source 405 and incident into the optical refractor 401 is reflected, refracted or scattered by the optical refractor 401 to generate a pattern image. It may be a triangle, such as a prism of 4, or a square such as a rectangle, trapezoid, or isosceles triangle.

Referring to the generation of the fingerprint image of FIG. 4, the user's 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 optical refractor 401 and enters the outer surface of the elastic pad 131 at an angle greater than a critical angle, reflection occurs in the valley 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 source 405 of FIGS. 4 and 5, and the light for image acquisition is at a right angle or at an angle smaller than the critical angle for total reflection. Is incident on the outer surface of Therefore, scattering occurs in the ridge of the fingerprint and refracted without total reflection in the valley, so that the uneven portion is bright and the remaining portion is dark.

When a pattern of the uneven surface 20a of the painting 20 is input, the operation within the second scanning unit 400 is the same as the process of obtaining a fingerprint image. However, instead of the fingerprint directly contacting the elastic pad 131, the painting 20 intermittently contact the elastic pad 131 using the elastic film 191 is different. 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. Accordingly, the elastic film 191 is disposed in parallel with each other while forming a space portion 190a between the elastic pad 131. When the user presses the elastic film 191 with the uneven surface 20a of the painting 20, the elastic film 191 in a state pulled by a certain tension covers the uneven surface 20a as it is. It is as if a thin film is covered on the uneven surface (20a) of the painting (20). As a result, the elastic pad 131 is stamped in the shape of the uneven surface 20a by the elastic film 191. Thereafter, light is emitted from the light source 405 to generate a painted image for the pattern of the uneven surface 20a in contact with the elastic pad 131.

<Second embodiment of the second scanning unit>

Alternatively, the second scanning unit 600 shown in FIG. 6 has a closed box shape and an elastic pad 131 is disposed on the open upper surface. The second scanning unit 600 includes a light source 601 that irradiates light toward the lower surface of the elastic pad 131, and a camera that directly photographs the elastic pad 131 under the elastic pad 131 to obtain a pattern image. It includes a part 610. The camera unit 610 may include a lens unit 611 and an image sensor 613.

The light source 601 may be located anywhere in the inner space where light can be irradiated toward the elastic pad 131 under the elastic pad 131. However, it is necessary to adjust so that the light emitted from the light source 601 does not enter the camera unit 610 directly. When inputting a fingerprint, the user's fingerprint is directly inputted through the elastic pad 131. 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 entering the painting, the light irradiated from the light source 601 to the elastic pad 131 is reflected or refracted between the elastic pad 131 and the elastic film 191 or between the elastic pad 131 and the space 190a. Alternatively, the image is imaged as a pattern of the concave-convex surface 20a of the painting 20 stamped on the elastic film 191 while being scattered, and is incident on the camera unit 610 through the elastic pad 131.

Referring to FIG. 3, an upper support part 630 made of a transparent material may be disposed on an upper surface of an open housing 171 to support all or part of the elastic pad 131. The upper support part 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 part 630 may be made of thin and transparent acrylic or synthetic resin.

On the other hand, if the elastic pad 131 has a certain hardness and can support the imprint of the painting 20, the upper support portion 630 may not be present.

<elastic pad>

The elastic pad 131 disposed on the upper surface of the second scanning unit 130 allows direct input of the fingerprint and at the same time facilitates input of the pattern of the seal 20, which is a rigid body, so that the uneven pattern of the fingerprint and the seal 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 painting 20, and is the same as the elastic pad of Korean Patent No. 1542818 or 1594114 and is applied for the same purpose. For example, even if the painting 20 is not stamped in the vertical direction and is inclined within a certain range and stamped, the elastic pad 131 is stamped with the uneven pattern of the painting 20, so there is no problem in generating a pattern image. In the case of a solid and flat pattern input surface like a typical seal scanner or fingerprint reader, even if the painting is tilted a little, a portion that is not in contact with the pattern input surface is compared to that which cannot generate an image.

Therefore, if the stamping direction of the hard coating 20 is roughly vertical, 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 bonded to the elastic pad 131 Is possible. Therefore, if the'elasticity' here is literally deformed and recovered, the degree of elasticity may be weak. For example, silicon or synthetic resin may be used as a material for the elastic pad 131.

In the case of generating a fingerprint image, even if it is considered that the fingerprint must be directly inputted to the elastic pad 131, it is preferable that the elasticity of the elastic pad 131 is not large. If the elastic pad 131 has elasticity and is sufficiently hard, there is no problem in inputting a 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 photorefractive device 401, forming an adhesive layer by a separate adhesive between the elastic pad 131 and the photorefractive device 401 may distort the optical path. It is not desirable because it can be.

Painting input section

The painting input unit 190 accommodates the elastic film 191. As briefly described above, the elastic film 191 of the painting input unit 190 is a component for generating a painting image together with the elastic pad 131.

The painting input unit 190 accommodates the elastic film 191 and has a dynamic structure such that it is moved to another place while inputting a fingerprint, and then is positioned on the upper surface of the elastic pad 131 when inputting a 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 moving between the upper surface of the elastic pad 131 and another point, or one vertical axis. It may be a rotating structure that rotates around the center.

The elastic membrane 191 is the same as the elastic membrane 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 scanning unit 130 of FIG. 3, the elastic film 191 is preferably opaque.

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

The elastic film 191 is a surface in which the uneven surface 20a of the painting 20 directly contacts. The elastic film 191 is bound to be contaminated when repeatedly stamped with the concave-convex surface 20a contaminated by ink or pad, but the elastic pad 131 is not affected by contamination of the elastic film 191 in the present invention. Does not. This is because even if the elastic film 191 is already contaminated, the elastic film 191 instead of the painting 20 presses the elastic pad 131 in the uneven shape of the painting 20. When the elastic layer 191 is made of an opaque material in the second scan unit 600 of FIG. 6, the elastic layer 191 may be contaminated.

Since the elastic film 191 is a sufficiently thin film, it is sufficient to input the shape of the uneven surface 20a of the painting 20 into the elastic pad 131 without distortion. For example, a thin film such as silicon, natural rubber, or synthetic resin You can use a membrane. For pattern input, the elastic film 1130 must be pulled with a certain tension during the stamping process to be able to press the elastic pad 131 in the shape of the uneven surface 20a.

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 Control to operate. In general, it is preferable that the first scan unit 110 and the second scan unit 130 are 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 are also operated in the standby mode, thereby reducing power consumption.

The scan control unit 151 may provide one of an identification card image generated by the first scan unit 110, a fingerprint image or a stamp image generated by the second scan unit 130 according to a scan command to an external device. 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.

Scanning system

The 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 multi-function scanner 100 and a user terminal 710, and the multi-function scanner 100 and the user terminal 710 are mutually connected through a wired or wireless communication interface. Can be connected.

The multifunctional scanner 100 of FIG. 4 further includes a first communication unit 153 that can be connected to a user terminal 710 in addition to the first and second scan units 110 and 130. The first communication unit 153 is connected to the second communication unit 711 of the user terminal 710 and provides the scanned image to the user terminal 710 at the request of the scan control unit 151.

The user terminal 710 includes a second communication unit 711, an input unit 713, and a terminal control unit 715.

The second communication unit 711 is connected to the first communication unit 153 of the multi-function scanner 100, and provides a scan command to the multi-function scanner 100 at the request of the terminal control unit (and the scanned image from the multi-function scanner 100). The input unit 713 receives a scan command from the user and provides it to the terminal control unit 715. 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 to request to generate one selected from an ID card image, a fingerprint image, and a stamp image.

If there is a fingerprint image in the ID card provided by performing the ID scan, the terminal control unit 715 may compare whether the printed fingerprint image and the fingerprint image scanned by the second scanning unit 130 are the same fingerprint. There are fingerprint images printed on some ID cards, such as ID cards. If there is a printed fingerprint image from the identification card image provided by the multi-function scanner 100, the terminal control unit 715 extracts the printed fingerprint image and extracts feature points. Thereafter, the terminal control unit 715 may extract feature points from the fingerprint image generated and provided by the second scanning 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 an identification card image scanned and provided by the first scanning unit 110 according to a scan command. If the second scanning unit 130 also subsequently generates and provides a fingerprint image and/or a stamp image as a series of processes, the terminal control unit 715 may store the fingerprint image and/or the stamp image by linking it to user information. have.
