Description

The present invention relates to a code image reading device, an identification device, and an automatic paper transaction device.

In recent years, as the workload of counter employees has been reduced due to cashless payments and business reforms, efficiency has been improved by promoting self-service counter operations. Measures are also being considered to make transfers of taxes and public funds self-sufficient, such as printing barcodes on transfer slips. Financial institutions can also equip automated teller machines with the ability to read code images printed on transfer slips, allowing users to process the transfer of taxes, public funds, etc. themselves, without having to go to a counter. It is possible to improve the efficiency of operations.

As an example of an automated teller machine equipped with such a code image reading function, Patent Document 1 discloses that an optical information reading section is arranged above the front panel, and a form placed on an operation panel, a mobile terminal, etc. An automatic transaction device is disclosed that reads a barcode displayed on an object to be read.

Japanese Patent Application Publication No. 2007-164367

However, the above-mentioned conventional technology has a problem in that it is difficult to read the code image stably and accurately. The reasons for this are as follows. For example, since the form is placed on the operation panel or operation screen of an automatic transaction device, the form may be deformed due to the effect of the difference in level of the operation panel or operation screen. Further, since the shape and size of the form and the position of the code image vary depending on the form, it is difficult to position the form at the optimal reading position of the reading device. Another reason is that when reading a code image displayed on a large screen of a mobile terminal such as a smartphone, the angle of the mobile terminal may not be appropriate or the illumination light may be reflected.

The purpose of the present invention is to solve the above problems and provide a code image reading device, an identity verification device, and an automatic paper transaction device that can stably and accurately read code images displayed on media. shall be.

In order to solve this problem, one aspect of the present invention provides a code image reading device that reads a code image displayed on a medium, the code image reading device being irradiated with reading light toward the bottom of the code image reading device. A code image reading section for reading, a reading control section for controlling the code image reading section, and a reading position of the code image that can be read by the code image reading section are projected on a surface opposite to the irradiation direction of the reading light or in the air. and a reading position display control section that controls the code image reading position display section to project the position on the opposing surface or in the air.

According to the present invention, for example, by making it possible to stably and accurately read code images displayed on media such as transfer forms, customers can automatically transfer taxes and public funds by themselves without having to process them at a counter. It becomes possible to operate the transaction device and process transactions smoothly. Therefore, it is possible to promote self-service counter operations.

[Embodiment 1]
(Configuration of automated teller machine 100 of Embodiment 1)
First, with reference to FIG. 1, the functional configuration of the automated teller machine 100 of this embodiment will be described. FIG. 1 is a diagram showing the functional configuration of an automated teller machine 100 according to the first embodiment.

The automated teller machine 100 includes an overall control section 10, a code image reading device 20, an operation screen 30, and an identity verification device 40. The code image reading device 20 includes a control section 21, a reading section 22, a code image position display section 23, and a form illumination 24. In addition, although the automatic teller machine 100 has a banknote unit, a currency unit, a passbook unit, a card unit, etc., illustration and description thereof are omitted.

The overall control unit 10 is a microprocessor that controls the entire automated teller machine 100 including each unit included in the automated teller machine 100.

The code image reading device 20 is located in the front of the automated teller machine 100, and is a CCD (Charge Coupled Device) scanning method that photographs a code image displayed on a form held over it by a user and provides it for code analysis. . The code image reading device 20 is not limited to the CCD type, but may be of other types such as a laser type.

Note that the code image reading device 20 is assumed to be an independent device. However, the code image reading device 20 may be included in an identification device such as a face imaging device or other devices.

The operation screen 30 is a display device that accepts a user's operation of the automated teller machine 100 using a touch panel, and also displays processing in the automated teller machine 100 and various information.

The identity verification device 40 reads the identity verification document held by the user held over the reading surface, communicates with an integrated circuit embedded in the identity verification document, and communicates with the face imaging unit provided in the automatic teller machine 100. (not shown) is used to verify the identity of the user who is the bearer of the identity verification document and form 1001.

The code image reading device 20 includes a control section 21 such as a microprocessor, a reading section 22, a code image position display section 23, and a form illumination 24.

The control section 21 includes a reading control section 211 , a code image position display control section 212 , a notification control section 213 , and an illumination control section 214 . The reading control section 211, the code image position display control section 212, the notification control section 213, and the illumination control section 214 are realized by executing a program.

The reading section 22 is controlled by a reading control section 211. The reading unit 22 reads a code image such as a barcode or two-dimensional code displayed on a form held by a user. Under the control of the reading control unit 211, the reading unit 22 has an angle adjustment function that determines the reading direction to further improve reading accuracy according to the size of the form on which the code image is displayed and the display position of the code image on the form. Mount. The reading unit 22 can read the code image 1002 displayed on the form 1001 held in the space between the operation screen 30 and the reading unit 22. The code image 1002 can be read by the reading unit 22 when aligned with the code image position guide 22C (see FIGS. 3 to 5).

The code image position display section 23 is controlled by the code image position display control section 212. The code image position display unit 23 irradiates a code image position guide 22C with reading light to indicate the position of the form and/or code image from which the reading unit 22 can read the code image displayed on the form held in the air. It is projected onto the opposite surface of the direction (on the operation panel 1000 of the automated teller machine 100 where the operation screen 30 is arranged). The code image position guide 22C may be projected in the air in the irradiation direction of the reading light. Alternatively, the code image position guide 22C may be displayed on the operation screen 30.

The form lighting 24 is controlled by a lighting control section 214. The form illumination 24 irradiates light onto the form whose code image is to be read and the code image.

FIG. 2 is a perspective view showing the automated teller machine 100 according to the first embodiment. FIG. 3 is an enlarged perspective view of the front portion of the automated teller machine 100 according to the first embodiment (in strict mode). FIG. 4 is an enlarged perspective view of the front portion of the automated teller machine 100 according to the first embodiment (in relaxation mode). FIG. 5 is a diagram showing a code image reading mode of the automated teller machine 100 according to the first embodiment.

As shown in FIG. 2, the code image reading device 20 is mounted on the front panel 101 of the automated teller machine 100. The reading unit 22 faces toward the operation screen 30 from below the code image reading device 20 so as to be able to read the code image.

The code image position display section 23 is housed inside the casing of the automatic teller machine 100, similarly to the code image reading device 20. As shown in FIG. 3, the code image position display section 23 is oriented so as to be able to project the reading position of the form and/or code image from below the code image reading device 20 toward the operation panel 1000 where the operation screen 30 is arranged. ing. The code image position display unit 23 displays the reading position of the form and/or code image in the air or on the surface of the casing 1 of the automatic teller machine 100 where the operation screen 30 is placed, by irradiating light. FIG. 3 shows a code image position guide 22C of the code image.

Note that the reading position and height of the form 1001 can also be set to positions moved left and right or up and down from the positions shown in FIGS. 3 and 4.

FIG. 4 shows the automated teller machine 100 in a "relaxed mode" in which the "reading mode" is relaxed compared to the "strict mode" of FIG.

As shown in FIG. 5, in the "strict mode", the reading range of the reading unit 22 is relatively narrow, the resolution is high, and the reading distance is short. In this way, in the "strict mode", the reading control unit 211 places emphasis on reading accuracy and gives priority to preventing code image reading errors. On the other hand, in the "relaxation mode", the reading range of the reading unit 22 is relatively wide, the resolution is low, and the reading distance is long. In this manner, in the "relaxation mode", the reading control unit 211 places emphasis on the reading speed and gives priority to quick code image reading. In other words, "strict mode" has high reading accuracy (low reading error rate) but is prone to reading failures (takes a long time to read), and "relaxed mode" has low reading accuracy (high reading error rate) but is more likely to fail. Easy to succeed (quick read).

Note that the "relaxation mode" may be set in stages such that the reading range gradually becomes wider, the resolution becomes higher, and the reading distance becomes longer. Similarly, "strict mode" may also have stages. Furthermore, the items that define the "reading mode" are not limited to the reading range, resolution, and reading distance.

At the beginning of reading the code image 1002, the "strict mode" is operated, and the code image position guide 22C is set to about twice the size of the code image to be read. Then, each time a reading error or a retry process occurs, the reading mode is relaxed and the code image position guide 22C is gradually enlarged to about three times the size of the code image, thereby making it easier to successfully read the code image. Even if the code image cannot be recognized, if the display and overall shape of the code image can be identified, the code image can be read by identifying the displayed position, adjusting the focus, and retrying the reading process. and the success probability of recognition can be increased.

(Code image reading process according to Embodiment 1)
FIG. 6 is a flowchart showing code image reading processing according to the first embodiment. The code image reading process according to the first embodiment is executed each time the reading unit 22 detects the form 1001 or the user instructs the user to start reading the code image.

First, in step S21, the reading control unit 211 detects the presence of the form 1001 in the image acquired by the reading unit 22, or the acceptance of an instruction from the user to start reading the code image from the operation screen 30 or the like.

Next, in step S22, the reading control unit 211 sets the "strict mode". Next, in step S23, the code image position display control section 212 controls the code image position display section 23 to display the code image position guide 22C.

Next, in step S24, the reading control unit 211 determines whether at least a part of the outline of the form 1001 or the code image 1002 has been detected. When the reading control unit 211 detects at least a part of the outline of the form 1001 or the code image 1002 (step S24 YES), the process proceeds to step S25, and when not detected (step S24 NO), the process proceeds to step S32. .

In step S25, the reading control unit 211 determines whether the code image 1002 can be read. The reading control unit 211 moves the process to step S26 when the code image 1002 can be read (step S25 YES), and moves the process to step S31 when the code image 1002 cannot be read (step S25 NO).

In step S26, the reading control unit 211 reads the code image 1002. During this reading, the reading control unit 211 may adjust the reading angle of the reading unit 22 so that it is easier to read the code image 1002 more accurately.

Next, in step S27, the identity verification device 40 performs authentication (identity verification processing) of the user who has read the code image 1002. If the authentication in step S27 is OK (step S28 YES), the identity verification device 40 moves the process to step S29, and if it is NG (step S28 NO), the process moves to step S34.

In step S29, the automated teller machine 100 executes form processing (transaction processing) regarding the form 1001 from which the code image 1002 has been read. Next, in step S30, the automated teller machine 100 outputs a statement related to the result of the form processing in step S29.

On the other hand, in step S31, the reading control unit 211 relaxes the "reading mode" by one step. Next, in step S32, the notification control unit 213 outputs an image display or audio output from the operation screen 30 that guides the form 1001 to the code image position guide 22C at the appropriate position of the code image 1002. In step S32, if the display of the code image and the shape of the entire form have been identified, the position of the code image may be estimated and the focus adjusted to this estimated position in preparation for the next reading process.

Next, in step S33, the control unit 21 determines whether a predetermined period of time has elapsed from the start of reading the code image 1002 (for example, step S23) and a timeout has occurred. The control unit 21 moves the process to step S34 when the timeout occurs (step S33 YES), and returns the process to step S25 when the timeout does not occur (step S33 YES).

In step S34, the control unit 21 outputs from the operation screen 30 a notification screen in which an error occurred in reading the code image 1002, or outputs audio.

(Example of guide display for code image reading operation according to Embodiment 1)
FIGS. 7 and 8 are diagrams showing examples of guide displays for code image reading operations of the automated teller machine 100 according to the first embodiment.

The guide display example in FIG. 7 is a diagram of the automatic teller machine 100 viewed from the front top. In the guide display example of FIG. 7, a guide 30D1 is displayed on the operation screen 30 or a guide is displayed on the operation panel 1000 so as to guide the code image 1002 displayed on the form 1001 into the frame of the code image position guide 22C. 33D2 is displayed. The icon mark of the code image may be projected into the air within the frame of the code image position guide 22C. Furthermore, by displaying operational guidance around this icon mark, the reading operation can be made intuitive and easy to understand.

At the start of reading the code image, the entire form 1001 or at least a part of the external shape is recognized, and based on the recognized image, the form 1001 is modified by referring to a database (not shown) that holds the external shape and size of the form 1001. Check the external shape and dimensions and estimate the position of the code image. Then, the estimated position of the code image may be superimposed and displayed on the photographed image of the form 1001, and the direction in which the form 1001 should be moved may be guided by arrows and voice guidance on the operation screen 30. However, the guidance is stopped when it is determined that the estimated position of the code image and the actual position of the code image are different. Furthermore, the code image whose position within the form has been estimated in this manner may be read by focusing on the estimated position as described above.

The guide display example in FIG. 8 is a diagram of the automatic teller machine 100 viewed diagonally from the front. In the guide display example shown in FIG. 8, the code image 1002 displayed on the form 1001 is guided in sequence using a display or audio output indicating the direction to move the code image 1002 into the frame of the code image position guide 22C (a) to (d). is displaying an animation.

(Effects of Embodiment 1)
In this embodiment, since the code image is read while holding the form in the air, there is no need to place the form 1001 on the operation panel 1000, and even if the form 1001 is long within the constraints of the automatic teller machine 100, the code image 1001 can be read. Further, the code image on the form 1001 can be stably read without being affected by irregularities on the operation panel 1000 due to the operation screen 30 or the like. For example, when placing a form on the operation screen 30 and reading a code image, if the size of the form 1001 is large, the form 1001 may protrude from the operation screen 30 or hit the frames on both sides, deforming the form and making it unstable. become in a state of not doing so. On the other hand, when reading the code image 1002 while holding the form 1001 in the air, the form 1001 is not deformed, so its shape is stable and the code image 1002 can be read quickly and accurately.

(Modification of Embodiment 1)
The code image position guide 22C may have a variable range depending on the reading performance of the reading unit 22 (code image reader), which changes depending on the environmental conditions (illuminance, etc.) around where the automatic teller machine 100 is installed. The illuminance around the automated teller machine 100 can be obtained from an illuminance sensor. Under environmental conditions where the reading performance of the reading section 22 is good, the range of the code image position guide 22C is widened to give priority to operability, and under environmental conditions where the reading performance is not good, the range of the code image position guide 22C is narrowed to improve reading accuracy. may be given priority.

When the reading unit 22 is a camera, when at least part of the shape of the form 1001 is captured but the code image 1002 cannot be read, the code image 1002 becomes readable based on the estimated position of the code image 1002 using the method described above. The direction and amount of movement of the form 1001 may be notified. Alternatively, the reading direction of the reading unit 22 may be changed toward the estimated position of the code image 1002. Furthermore, even when the code image 1002 is captured but has not reached the reading position, the direction and amount of movement may be notified to the user.

In addition, the code image reading device 20 has a security mode, and when the security mode is set, the reading range by the reading unit 22 is narrower than in the normal mode, so that the form 1001 is not exposed to unnecessary light, etc. A notification may be made to guide the form 1001 from the periphery of the device 100 to a position that is a blind spot, and the code image 1002 may be read at that position. By doing so, the effect of protecting the personal information written in the form 1001 can be expected.

[Embodiment 2]
FIG. 9 is a perspective view showing an automated teller machine 100B according to the second embodiment. In this embodiment, the code image position guide 22C of the code image reading device 20B is arranged in front of the operation screen 30.

In this embodiment, the code image reading device 20B mounted in the upper center of the front panel 101 of the automatic teller machine 100B, as in the first embodiment, determines the size of the form 1001 that displays the code image 1002 and the display position of the code image 1002. The reading angle can be adjusted. Further, the code image reading device 20B illuminates the code image position guide 22C in front of the operation screen 30 and reads the code image 1002 of the form 1001 with one side of the form 1001 placed on one end side of the operation panel 1000. Can be done. By placing one side of the form 1001 on one end side of the operation panel 1000, the stability of the form 1001 is increased, and the code image reading device 20B can stably read the code image 1002.

[Embodiment 3]
10 and 11 are perspective views showing an automated teller machine 100C according to the third embodiment.

As shown in FIGS. 10 and 11, the code image reading device 20C is located at the front panel 101 of the automated teller machine 100C and the passbook inlet/exit and card inlet/outlet of the automated teller machine 100C below the code image reading device 20C. The document height guide display section 25 is provided on a substantially vertical surface. As shown in FIG. 11, the form height guide display unit 25 displays the height position at which the form 1001 is held in the air when reading the code image 1002 using a lamp or a display. Note that the document height guide display section 25 similarly changes and displays the height position according to the reading mode shown in the first embodiment. Note that the form height guide display section 25 may be an easily visible label instead of a light notification means such as a lamp or a display.

[Embodiment 4]
12 and 13 are perspective views showing an automated teller machine 100D according to the fourth embodiment. The code image reading device 20D of this embodiment differs in that it includes a form placement table 26 instead of the form height guide display section 25 of the third embodiment. As shown in FIG. 13, the form placement table 26 is provided on a substantially vertical plane where the passbook entry/exit and card entry/exit of the automated teller machine 100D are located, and allows the form 1001 to be held stably by placing one end of the form 1001 thereon. can be supported. Therefore, the stability of the form 1001 is increased, and the code image reading device 20D can stably read the code image 1002.

[Embodiment 5]
FIG. 14 is a diagram showing the functional configuration of an automated teller machine 100E according to the fifth embodiment. The automated teller machine 100E differs from the automated teller machine 100 of Embodiment 1 in that the code image reading device 20E includes a distance measuring section 215 and a distance sensor 27 in the control section 21E.

The distance sensor 27 is a reflective sensor mounted inside the code image reading device 20E of the automated teller machine 100E. The distance measurement unit 215 uses the distance sensor 27 to obtain distance information from the reading unit 22 to the form 1001. For example, distance information is acquired when reading the code image 1002 starts. Based on the acquired distance information, the notification control unit 213 notifies the current height of the form 1001 and the height of the form 1001 appropriate for reading the code image 1002 through the operation screen 30 or audio output, and 1001 to an appropriate height position.
