Abstract

PROBLEM TO BE SOLVED: To provide a medium image reader and a medium image identifying system using the same, permitting precise readout of the image of a medium such as an identification card and accurate true-falsehood discrimination thereof. SOLUTION: The medium such as an identification card 1 to be read out is irradiated with a white light from a light source 22a and its surface image is read out. Further, it is irradiated with an infrared light from a light source 22b and its surface image is read out. Such image information is transmitted to a manager 40 together with reference image information for a true driver's license which is previously read out and stored in a reference image storage part 28, and displayed in contrast on a monitoring device 43. Thus, the medium printed with, for example, a special ink reflecting the infrared light can be accurately identified, leading to easy true-falsehood discrimination.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art Conventionally, automatic contract receiving systems used in consumer financial institutions and the like include unattended contract terminals installed in a plurality of branches, management devices installed in centers such as head offices,
And a communication line connecting them. Normally, there is no clerk on the unattended contract terminal side, and the customer operates the terminal in accordance with an instruction from a clerk on the management device side transmitted via a communication line.

[0003] The unattended contract terminal includes a video camera for monitoring and confirming the operation status of the customer, a display device for giving an operation instruction to the customer, a touch panel for the customer to operate according to the instruction, and a contract application form or the like presented. A medium image reading device for reading an image of a medium such as an identification card is provided. On the other hand, the management device is a combination of a computer for registering and managing customer information and a monitor device for monitoring, etc., in which a clerk grasps the state of the customer on a screen projected on the monitor device and gives an appropriate operation instruction. Is available.

In such an automatic contract receiving system, a customer who visits a branch sets a contract application form and an identification card on a medium image reading apparatus and presents them in accordance with operation instructions shown on a display device. The contract application form is a form in which a customer fills in an application form provided at a branch office. The most common type of identification card is a driver's license with a photo taken by a public organization, followed by a health insurance card or passport. The medium image reading device uses an optical photographing device such as a camera or a scanner, and photographs the reflection of irradiated light as a color image.

The presented contract application form and identification card are read by a medium image reading device on a reflection image of the surface, transmitted to a management device of a center, and displayed on a screen of a monitor device. The clerk at the center determines the authenticity of the identification card by displaying on the monitor device, and compares the photograph of the face of the identification card with the face of the customer who is photographed and transmitted by the camera for customer confirmation. Confirm the identity of the person and judge the contract. As a result of the examination, if there is no problem, the contract is concluded, and the clerk controls the management device and prints and issues a passbook, a card, and the like from the unattended contract terminal.

As a result of the examination, if there is no problem, the contract is concluded, and the clerk controls the unattended contract terminal 10 from the management device 40, and a card reader (not shown).
A card is issued from the issuing unit, and a passbook is issued from the passbook reader / printing / issuing unit.

As described above, the automatic contract receiving system according to the present embodiment has the following advantages. (1) In addition to the white light source 22a, the infrared light source 2
2b. As a result, in order to prevent forgery, for example, the driver's license 1 or the like printed with a special ink that absorbs or reflects only infrared light can be reliably identified.

(2) Compare the reference image information with the reference image storage unit 28 which reads in advance the real driver's license with infrared light and stores it as reference image information, and the driver's license 1 presented by the customer. An image processing unit 27 is provided. As a result, it is possible to reduce the examination work of the staff on the management device 40 side.

(3) Driver's license 1 read with white light
In addition to the above image information, the image processing unit 27 outputs image information read by infrared light, reference image information read in advance by infrared light, and information of a comparison result. This makes it possible to simultaneously display these three images and the comparison result on the monitor device 43 of the management device 40,
Authentication can be easily determined.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, there are the following modifications. (A) In the medium image reading device 20, the light sources 22a and 22b of different wavelength bands are switched to irradiate the medium to be read with light of each wavelength band to read the image. The medium to be read may be irradiated with light using a light source capable of outputting a wide range of wavelengths, and read by optical sensors in different wavelength bands. Thereby, a similar effect can be obtained.

(B) The reference medium information is stored in advance in the reference image storage unit 28, and the image processing unit 27 compares the image information of the driver's license presented by the customer with the reference medium information. However, the image processing unit 27 may transmit the reference medium information to the management device 40 side in addition to the image information without performing the comparison processing. Thereby, the comparison process on the unattended terminal device side is eliminated, and the processing amount of the unattended terminal device can be reduced.

(C) The reference medium information is stored in the reference image storage unit 28 in advance, and the image processing unit 27 compares the image information of the driver's license presented by the customer with the reference medium information. However, the management apparatus 40 may store the reference medium information, and compare the image information transmitted from the unmanned contract apparatus with the reference medium information. Accordingly, it is not necessary to transmit the reference medium information and the comparison result each time from the unmanned terminal device side, and the scale and processing amount of the unmanned terminal device can be further reduced.

(D) The light source 22b emits infrared light, but may emit ultraviolet light or specific monochromatic light depending on the characteristics of the printing ink. This allows
The authenticity can be easily determined in correspondence with the printing ink.

(E) The number of light sources 22a and 22b is not limited to two. If necessary, light sources of three or more different wavelength bands may be used. As a result, the authenticity may be more easily determined.

(F) The light sources 22a and 22b are arranged on the same side of the medium as the CCD 24 so as to read the reflected light, but may be arranged on the opposite side of the CCD 24 to read the transmitted light. good.

(G) In order to irradiate different wavelength bands, two light sources 22a and 22b having different wavelength bands are switched to emit light. However, a single luminous body having a wide wavelength band is used. The filters may be switched to irradiate different wavelength bands.
