Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following embodiments are merely examples including the drawings and do not limit the present invention. In each of the drawings for explaining the following embodiments, the same reference numerals indicate components or processes having the same or similar functions, and the subsequent explanations will be omitted. Also, each embodiment, each example, and each modification can be partially or wholly appropriately combined within the scope and consistency of the technical idea of the present invention.

[0011] In the following embodiments, the vertical direction (upper direction, upward) of the device housing of the cash automated transaction device is the positive direction of the Z-axis, and the direction from the user side (front side, forward) to the opposite side (rear side, backward) of the device housing is the positive direction of the Y-axis. Also, the direction from the left side to the right side toward the user side of the device housing is the positive direction of the X-axis. In the description of the following embodiments, a right-handed XYZ coordinate system in which the X-axis, Y-axis, and Z-axis are orthogonal to each other is used.

[0012] Note that in the following embodiments, the directions and positions represented by "upper", "lower", "left", "right", "front", "rear", "back", etc. are merely relative, and the orientation, shape, or size of the cash automated transaction device and its components are not limited by the XYZ coordinate system. Also, the number of components in the description and illustration of the embodiments is merely an example.

[0013] In the following embodiments, as an example of a paper sheet automatic transaction device, a cash automated transaction device that handles banknotes as paper sheets will be described as an example. However, it is not limited to this, and the same can be applied to various other paper sheets such as checks and gift certificates.

[0014] Furthermore, although the following embodiments describe the reading of code images written on a form, code images displayed on any medium, including the screen of a terminal device, may also be used as the target of reading.

[0015] In the following description, explanations of matters not directly related to the technology disclosed in the embodiments may be omitted as appropriate.

[0016] [Embodiment 1] (Overall configuration of the automated cash transaction device 1000 in Embodiment 1) First, the overall configuration of the automated cash transaction device 1000 of this embodiment will be described with reference to Figure 1. Figure 1 is a diagram showing the configuration of the automated cash transaction device 1000 according to Embodiment 1.

[0017] The automated cash transaction machine 1000 comprises an overall control unit 10, a face imaging device (face camera unit) 1200, an operation screen 1005, and an identity verification device 1100. The face imaging device (face camera unit) 1200 comprises a document reading device 11 and a face imaging unit 1201. In addition, the automated cash transaction machine 1000 has a banknote unit, a coin unit, a passbook unit, a card unit, etc., but these are not shown in the illustration.

[0018] The overall control unit 10 is a microprocessor that is responsible for the overall control of the automated cash transaction machine 1000, including each unit that the automated cash transaction machine 1000 has.

[0019] The face imaging unit 1201 is, for example, a camera located on the front of the ATM 1000 that captures the face of the user.

[0020] The operation screen 1005 is a display device that accepts requests for operation of the automated cash transaction machine 1000 from users of the automated cash transaction machine 1000, and also displays processing and various information from the automated cash transaction machine 1000.

[0021] The identity verification device 1100 reads the identity verification document held over the reading surface, communicates with the integrated circuit embedded in the identity verification document, and uses the image of the user's face captured by the face imaging unit 1201 to verify the identity of the user who is presenting the identity verification document.

[0022] The document reading device 11 includes a control unit 111 such as a microprocessor, a document imaging unit 1202, a code image reading unit 1203, a document placement range display unit 1202L, a code image reading position display unit 1203L, and a document illumination unit 1204.

[0023] The document imaging unit 1202 is, for example, a camera that captures an image of a document 1004, such as a transfer form, placed on the operation surface 1007 on the front of the automated teller machine 1000, where the operation screen 1005 is located. The operation screen 1005 and the operation surface 1007 are examples of predetermined surfaces facing the direction of reading the code image.

[0024] The code image reading unit 1203 is, for example, a barcode reader that reads code images 1004C, such as barcodes and two-dimensional codes, written on a form 1004 placed on the operation surface 1007. The code image reading unit 1203 is equipped with a function that allows angle adjustment to determine the reading direction according to the size of the form 1004 and the position of the code image 1004C on the form 1004. The code image reading unit 1203 is placed within the frame of the placement area 1206 (Figures 3 and 4 (form markers)) around the coin slot and banknote slot of the ATM 1000, or within the screen of the operation screen 1005 (Figure 4), and is capable of reading code images 1004C aligned to the reading position 1205 (Figures 2 and 3 (barcode markers)).

[0025] Alternatively, instead of the code image reading unit 1203, the code image 1004C written on the document 1004 may be read by analyzing the image of the document 1004 captured by the document imaging unit 1202.

[0026] The document placement range display unit 1202L displays on the operation surface 1007 the placement range in which the document 1004 can be photographed by the document imaging unit 1202 when the document 1004 is placed on the operation surface 1007. The document placement range display unit 1202L displays the placement range on the operation surface 1007 by illuminating it with light. Alternatively, the document placement range display unit 1202L may be the operation screen 1005, and the placement range may be displayed as a screen display on the operation screen 1005.

[0027] The code image reading position display unit 1203L displays the reading position 1205 of the code image 1004C that the code image reading unit 1203 can read when reading the code image 1004C of the form 1004 placed on the operation surface 1007 using the code image reading unit 1203, on the operation surface 1007 facing the reading direction of the code image 1004C. Alternatively, the code image reading position display unit 1203L may be the operation screen 1005, and the reading position 1205 may be displayed as a screen display on the operation screen 1005.

[0028] The form illuminator 1204 illuminates the form 1004 placed on the operating surface 1007. The form illuminator 1204 provides sufficient light to the form 1004 when the form imaging unit 1202 captures an image.

[0029] The control unit 111 is a microprocessor and includes a document imaging control unit 1111, a code image reading control unit 1112, a code image reading position display control unit 1113, a document placement range display control unit 1114, and a document illumination control unit 1115.

[0030] The document imaging control unit 1111 controls the document imaging unit 1202 to capture an image of the document 1004. The document imaging control unit 1111 also adjusts the angle that determines the shooting direction when the document imaging unit 1202 captures the document 1004. Furthermore, the document imaging control unit 1111 identifies the size of the document 1004 and the position of the code image 1004C on the document 1004 from the image of the document 1004 captured by the document imaging unit 1202.

[0031] The code image reading control unit 1112 controls the code image reading unit 1203 to read the code image 1004C written on the form 1004 placed on the operating surface 1007. The code image reading control unit 1112 also adjusts the angle that determines the reading direction of the code image reading unit 1203 when reading the code image 1004C. Furthermore, the code image reading control unit 1112 adjusts the reading direction of the code image reading unit 1203 according to the size of the form 1004 and the position of the code image 1004C, as identified by the form imaging control unit 1111.

[0032] The code image reading position display control unit 1113 controls the code image reading position display unit 1203L to display the reading position 1205 of the code image 1004C on the operating surface 1007. The code image reading position display control unit 1113 adjusts the display position of the reading position 1205 according to the reading direction adjusted by the code image reading control unit 1112. The display position and size of the reading position 1205 may be fixed or variable.

[0033] The document placement area display control unit 1114 controls the document placement area display unit 1202L to display the placement area 1206 on the operation surface 1007. The display position and size of the placement area 1206 may be fixed or variable. The document placement area display control unit 1114 may also control the document placement area display unit 1202L to adjust the display position or size of the placement area 1206 on the operation surface 1007 or operation screen 1005 according to the size of the document 1004 and the position of the code image 1004C identified by the document imaging control unit 1111.

[0034] The document illumination control unit 1115 controls the document illumination 1204 to adjust the amount of light supplied to the document 1004 when the document imaging unit 1202 captures an image. The document illumination control unit 1115 adjusts the direction of light irradiation to the document 1004 according to the position of the document 1004 identified by the document imaging control unit 1111. After the document illumination control unit 1115 adjusts the direction of light irradiation to the document 1004, the document imaging control unit 1111 controls the document imaging unit 1202 to capture a recorded image of the document 1004.

[0035] Figure 2 is a perspective view showing the automated cash transaction device 1000 according to Embodiment 1. Figures 3 and 4 are enlarged perspective views showing the front portion 1000F of the automated cash transaction device 1000 according to Embodiment 1. Figure 5 is a cross-sectional view showing the configuration of the face imaging device 1200 included in the automated cash transaction device 1000 according to Embodiment 1.

[0036] In this embodiment, the document reading device 11 is described as being provided in the face imaging device 1200. However, the document reading device 11 may be an independent configuration or may be provided in a separate unit.

[0037] As shown in Figure 2, the face imaging device 1200 is mounted on the front panel 1001 of the ATM 1000. Also, as shown in Figure 5, the face imaging device 1200 has a face imaging unit 1201 and a document reading device 11 located below the face imaging unit 1201 (on the negative Z-axis side). The face imaging device 1200 is a type of identity verification device because it captures images of the user's face for identity verification.

[0038] Note that Figure 5 merely shows an example of the arrangement and orientation of the document imaging unit 1202, the code image reading unit 1203, and the document illumination unit 1204 of the document reading device 11. In other words, the arrangement and orientation of the document imaging unit 1202, the code image reading unit 1203, and the document illumination unit 1204 can be adjusted as appropriate to improve the reading accuracy of the document imaging unit 1202 and the code image reading unit 1203.

[0039] As shown in Figure 3, the document placement range display unit 1202L, by illuminating with light, displays on the operating surface 1007 the placement range 1206 in which the document 1004 can be photographed by the document imaging unit 1202 when the document 1004 is placed. Although not shown in the illustration, in this case, the document placement range display unit 1202L is provided around the document imaging unit 1202 of the document reader 11.

[0040] Furthermore, as shown in Figure 3, the code image reading position display unit 1203L displays the reading position 1205 when reading the code image 1004C using the code image reading unit 1203 on the operating surface 1007 facing the reading direction of the code image 1004C. Although not shown in the figure, in this case, the code image reading position display unit 1203L is provided around the document imaging unit 1202 of the document reading device 11.

[0041] Alternatively, as shown in Figure 4, the document placement range display unit 1202L may be the operation screen 1005. That is, when the document 1004 is placed, the placement range 1206 in which the document 1004 can be photographed by the document imaging unit 1202 is displayed on the operation screen 1005.

[0042] Furthermore, as shown in Figure 4, the code image reading position display unit 1203L may also be the operation screen 1005. That is, the reading position 1205 when reading the code image 1004C using the code image reading unit 1203 is displayed on the operation screen 1005 facing the reading direction of the code image 1004C.

[0043] The form 1004 is placed in the coin slot and banknote slot placement area 1206 (Figure 3) at the back of the operation screen 1005, or in a predetermined position within the operation screen 1005 (Figure 4), and its barcode or 2D code is read. To prevent accidental contact with the operation screen 1005 when placing the form 1004 in the predetermined position, or to prevent the touch sensors on the operation screen 1005 from reacting unintentionally when placing the form 1004 on the operation screen 1005, the touch sensors in a predetermined area of ​​the operation screen 1005 are disabled, or the buttons on the operation screen 1005 necessary for operation are consolidated and arranged in a part of the screen (for example, the bottom). In this way, a place to stably place the long and large form 1004 can be secured within the space constraints on the automated cash transaction machine 1000.

[0044] The reading position 1205 and the placement range 1206 may be displayed on either the operation screen 1005 or the operation surface 1007, or both.

[0045] (Document reading process according to Embodiment 1) Figure 6 is a flowchart showing the document reading process according to Embodiment 1. The document reading process according to Embodiment 1 is executed each time the document imaging control unit 1111 detects a document 1004.

[0046] First, in step S11, the document imaging control unit 1111 detects from the image acquired by the document imaging unit 1202 that a document 1004 is present on the operating surface 1007, and also detects the outline of the detected document 1004.

[0047] Next, in step S12, the code image reading position display control unit 1113 controls the code image reading position display unit 1203L to display the reading position 1205 of the code image 1004C. Also in step S12, the form placement range display control unit 1114 controls the form placement range display unit 1202L to display the placement range 1206 of the form 1004.

[0048] Next, in step S13, the document imaging control unit 1111 adjusts the angle that determines the shooting direction of the document imaging unit 1202 according to the placement range 1206. Alternatively, in step S13, the code image reading control unit 1112 adjusts the angle that determines the reading direction of the code image reading unit 1203 according to the reading position 1205. Also in step S13, the document placement range display control unit 1114 adjusts the display position or size of the placement range 1206 or reading position 1205 on the operation surface 1007 or operation screen 1005 according to the size of the document 1004 and the position of the code image 1004C.

[0049] Next, in step S14, the document imaging control unit 1111 determines whether the position of the document 1004 is within the placement range 1206 and the position of the code image 1004C is at the reading position 1205. If the position of the document 1004 is within the placement range 1206 and the position of the code image 1004C is at the reading position 1205 (step S14 YES), the document imaging control unit 1111 moves to step S15. On the other hand, if the position of the document 1004 is outside the placement range 1206 or the position of the code image 1004C is not at the reading position 1205 (step S14 NO), the document imaging control unit 1111 moves to step S21.

[0050] In step S15, the code image reading control unit 1112 controls the code image reading unit 1203 to read the code image 1004C. Next, in step S16, the control unit 111, in accordance with the result of reading the code image 1004C in step S15, coordinates with the face imaging unit 1201 and the identity verification device 1100 via the overall control unit 10 to perform an authentication process (user identity verification process) to verify the user's face photograph and identity verification documents. Next, in step S17, the control unit 111 determines whether the authentication result in step S16 is OK. If the authentication result in step S16 is OK (step S17 YES), the control unit 111 moves the process to step S18. On the other hand, if the authentication result in step S16 is NG (step S17 NO), the control unit 111 moves the process to step S23.

[0051] In step S18, the control unit 111, via the overall control unit 10, cooperates with various units of the ATM 1000 and executes processing related to the document 1004 from which the code image 1004C was read. Next, in step S19, the document imaging control unit 1111 captures a recording image of the entire or a part of the document 1004 from which the code image 1004C was read. Next, in step S20, the control unit 111, via the overall control unit 10, cooperates with the transaction details printing unit (not shown) and outputs a transaction details 1008 that prints the entire document 1004 (or the part containing important information) as shown in Figure 11. It outputs a transaction details 1008 having a document printing section 1008T that prints the entire (or a part) of the document 1004 as shown in Figure 7. Compared to the conventional usage statement 1009 shown in Figure 8, the usage statement 1008 includes an additional form printing section 1008T, which is a printout of the entire form 1004 (or a portion thereof).

[0052] Meanwhile, in step S21, the control unit 111 guides the user in the direction in which the code image 1004C of the document 1004 can be read, according to the current positions of the document 1004 and the code image 1004C. The current positions of the document 1004 and the code image 1004C are determined, for example, by the document imaging control unit 111 analyzing the image taken by the document imaging unit 1202. The control unit 111 calculates the difference between the current positions of the document 1004 and the code image 1004C and the placement range 1206 and the reading position 1205. From this calculation result, the control unit 111 guides the user, via image output from the operation screen 1005 and audio output from the speaker (not shown), on which direction and how far the document 1004 should be moved to reach the placement range 1206 and the code image 1004C written on the document 1004 to reach the reading position 1205.

[0053] Next, in step S22, the control unit 111 determines whether it failed to read the code image 1004C within the time limit and a timeout occurred. If a timeout occurred (step S22 YES), the control unit 111 moves the process to step S23; otherwise, it returns the process to step S14.

[0054] In step S23, the control unit 111 notifies the user of an error indicating that the code image 1004C could not be read within the time limit, by outputting an image from the operation screen 1005 and an audio output from a speaker (not shown).

[0055] Furthermore, when reading the code image 1004C in step S15, the document 1004 in step S19 may be photographed at the same time.

[0056] Figures 9 to 11 are diagrams illustrating an example of a document reading operation in the automated cash transaction device 1000 according to Embodiment 1, and show an example of an operation screen illustrating the operation of placing a document 1004 to be displayed on the operation screen 1005 of the automated cash transaction device 1000.

[0057] The example of the operation screen in Figure 9 shows the case where the form 1004 is placed on the coin slot and banknote slot of the ATM 1000 located behind the operation screen 1005. Using a view from the front and top of the ATM 1000, the animations (a) to (d) are displayed to guide the form 1004 into the frame of the placement area 1206 and to guide the code image 1004C to the reading position 1205.

[0058] The example of the operation screen in Figure 10 shows the case where the form 1004 is placed on the coin slot and banknote slot of the ATM 1000 located behind the operation screen 1005. Using a view of the ATM 1000 from the front right at an angle, the animations (a) to (d) are displayed to guide the form 1004 into the frame of the placement area 1206 and to guide the code image 1004C to the reading position 1205.

[0059] The example of the operation screen in Figure 11 shows the case where the form 1004 is placed at a specified position on the operation screen 1005. The operation screen 1005 of the ATM 1000 displays the placement range 1206 of the form 1004 to guide the user, and also displays the reading position 1205 of the code image.

[0060] In the example operation screens shown in Figures 9 to 11, to prevent accidental touching when placing the form 1004 on the operation screen 1005, and to prevent the touch sensor from reacting when the form 1004 is placed on the operation screen 1005, the area where the form 1004 is placed is disabled, and the buttons on the operation screen 1005 necessary for operation are placed at the bottom of the screen.

[0061] [Embodiment 2] Figures 12 to 14 and 16 to 24 show an example of the identity verification device 1100B of Embodiment 2, which adds a function to read barcodes and 2D codes printed on a form 1004 to the identity verification device 1100 installed in the automated cash transaction device 1000 of Embodiment 1. In Embodiment 2, the explanation will focus on the differences from Embodiment 1, and the explanation of the same configuration and processing as in Embodiment 1 will be omitted.

[0062] (Configuration of the ATM 1000B and identity verification device 1100B in Embodiment 2) First, the overall configuration of the automated cash transaction device 1000B of this embodiment will be described with reference to Figure 12. Figure 12 is a diagram showing the configuration of the automated cash transaction device 1000B according to Embodiment 2. Figure 13 is a perspective view showing the identity verification device 1100B provided in the automated cash transaction device 1000B according to Embodiment 2. Figure 14 is a cross-sectional view showing the identity verification device 1100B provided in the automated cash transaction device 1000B according to Embodiment 2.

[0063] Compared to the automated cash transaction device 1000 of Embodiment 1, the ATM 1000B differs in that its identity verification device 1100 includes a document reader 11B, a contactless IC reader control unit 1104, and a contactless IC reader antenna 1105.

[0064] The document reading device 11B includes a control unit 111B such as a microprocessor, a document imaging unit 1103, and a first illumination unit 1106.

[0065] The document imaging unit 1103 is, for example, a camera that captures an image of the surface of an identity verification document, such as a driver's license or My Number Card, placed on the reading surface 1102 (Figure 13) of the identity verification device 1100. Identity verification documents are just one example of specific documents. The reading surface 1102 is translucent.

[0066] The first illumination 1106 shines illumination light onto the identity verification document placed on the reading surface 1102. This illumination light provides sufficient light to the surface of the identity verification document when it is being photographed.

[0067] The control unit 111B is a microprocessor and includes a document imaging control unit 1111B and an illumination control unit 1115B. The document imaging control unit 1111B controls the document imaging unit 1103 to capture an image of the surface of the identification document placed on the reading surface 1102.

[0068] The lighting control unit 1115B controls the first light 1106 and adjusts the amount of light illuminating the surface of the identification document when photographing it.

[0069] The contactless IC reader control unit 1104 reads the contactless IC chip information stored in the integrated circuit (not shown) embedded in the identity verification document placed on the reading surface 1102 via the contactless IC reader antenna 1105, and passes it to the control unit 111B. The contactless IC chip information includes personal information and is used during the identity verification process.

[0070] The identity verification document is placed on the reading surface 1102, and while the first illumination 1106 is shining on it, the document imaging unit 1103 captures an image of the surface of the identity verification document, while the contactless IC reader control unit 1104 and contactless IC reader antenna 1105 read the contactless IC chip information.

[0071] In the conventional identity verification device 1100, as shown in Figure 15, a second illumination 1107 is provided on wall sections 1107W that are erected in the positive Z-axis direction along the X-axis direction at both ends in the Y-axis direction. This second illumination 1107 irradiates the identity verification document placed on the reading surface 1102 from the opposite side of the reading surface 1102, for example, with special light. In the conventional identity verification device 1100, when a form 1004 larger than the identity verification document is placed on the reading surface 1102 and read by the document imaging unit 1103, the distance between the form 1004 and the reading surface 1102 increases due to the wall sections 1107W. In other words, when the document imaging unit 1103 takes an image of the form 1004 through the reading surface 1102, the distance to the form 1004 becomes too great, resulting in a lack of focus and other factors that could lead to shooting failures.

[0072] On the other hand, the identity verification device 1100B of the second embodiment removes the wall portion 1107W that was a cause of shooting failure, and configures the device so that when the form 1004 is placed on the reading surface 1102 and read by the document imaging unit 1103, the form 1004 and the reading surface 1102 are parallel and close to each other at a predetermined distance or less. As a result, the identity verification device 1100B can reliably read the image of the face of the identity verification document and the code image written on the form 1004 with the reading surface 1102.

[0073] Furthermore, the identity verification device 1100B may be equipped with a third light (not shown), and the reading position when reading the code image may be projected onto the reading surface 1102 by controlling the third light by the light control unit 1115B. By placing the form 1004 on the reading surface 1102 with the projected reading position as the target, the user can have the identity verification device 1100B quickly read the code image 1004C written on the form 1004.

[0074] (Document reading process according to Embodiment 2) Figure 16 is a flowchart showing the document reading process according to Embodiment 2. The document reading process according to Embodiment 2 differs from the document reading process according to Embodiment 1 (Figure 6) in that steps S11B and S12B are executed instead of steps S11 and S12, and step S13 is omitted. Otherwise, the document reading process according to Embodiment 2 is the same as the document reading process according to Embodiment 1. The document reading process according to Embodiment 2 is executed each time the presence of a document 1004 on the reading surface 1102 is detected.

[0075] In step S11B, the document imaging control unit 1111 detects from the image acquired by the document imaging unit 1103 that a document 1004 is present on the reading surface 1102, and detects a code image 1004C from the detected document 1004. Next, in step S12B, the control unit 111B guides the user to the reading position of the code image 1004C by displaying it on the operation screen 1005. For example, the control unit 111B displays an image of the identity verification device 1100B including the reading surface 1102 on the operation screen 1005, indicating which position on the reading surface 1102 is the reading position for the code image 1004C.

[0076] (Configuration of the identity verification device 1100B1 in modified example 1 of Embodiment 2) Figure 17 is a perspective view showing the identity verification device 1100B1 provided in the automated cash transaction device 1000B according to Modification 1 of Embodiment 2. Figure 18 is a cross-sectional view showing the identity verification device 1100B1 provided in the automated cash transaction device 1000B according to Modification 1 of Embodiment 2.

[0077] Unlike the identity verification device 1100B, the identity verification device 1100B1 has a wall portion 1107W on only one end in the Y-axis direction. As a result, when the identity verification device 1100B1 places the form 1004 on the reading surface 1102 and reads it with the document imaging unit 1103, it can move one end of the form 1004 towards the wall portion 1107W, thereby bringing the form 1004 and the reading surface 1102 closer together. This allows the identity verification device 1100B to stably read the image of the identity verification document and the code image written on the form 1004 on the reading surface 1102.

[0078] (Configuration of the identity verification device 1100B2 in modified example 2 of Embodiment 2) Figure 19 is a perspective view showing the identity verification device 1100B2 provided in the automated cash transaction device 1000B according to Modification 2 of Embodiment 2. Figure 20 is a cross-sectional view showing the identity verification device 1100B2 provided in the automated cash transaction device 1000B according to Modification 2 of Embodiment 2.

[0079] The identity verification device 1100B2 according to Modification 2 differs from the identity verification device 1100B in that it is provided with wall sections 1107W equipped with second illuminations 1107 at both ends in the Y-axis direction. The illumination control unit 1115B adjusts the amount of light that the second illuminations 1107 emit from the opposite side of the reading surface 1102 to the identity verification document placed on the reading surface 1102. The identity verification device 1100B2 is equipped with a code image reading unit 1203 that reads the code image written on the form 1004, which is placed so as to span the two wall sections 1107W, by passing it through the reading surface 1102. As a result, in addition to reading the image on the face of the identity verification document on the reading surface 1102, the code image written on the form 1004 can be read with high accuracy even if the form 1004 is placed on a step formed by the wall sections 1107W.

[0080] (Configuration of the identity verification device 1100B3 in modified example 3 of Embodiment 2) Figure 21 is a perspective view showing the identity verification device 1100B3 included in the automated cash transaction device 1000B according to the third modification of Embodiment 2. Figure 22 is a cross-sectional view showing the identity verification device 1100B3 included in the automated cash transaction device 1000B according to the third modification of Embodiment 2.

[0081] The identity verification device 1100B3 according to Modification 3 differs from the identity verification device 1100B in that it is provided with wall sections 1107W equipped with second illuminations 1107 at both ends in the Y-axis direction. Furthermore, the identity verification device 1100B3 is equipped with a document slit 1109 below the two wall sections 1107W and the second illuminations 1107 (in the negative Z-axis direction). By inserting a document 1004 into the document slit 1109, the code image written on the document 1004 approaches the reading surface 1102 at a predetermined distance or less, and the focal point of the document imaging unit 1103 is positioned on the document 1004, so that the code image written on the document 1004 can be read with high accuracy.

[0082] The identity verification device 1100B3 may also be configured such that a wall section 1107W is provided with a second illumination 1107 at only one end in the Y-axis direction. In this case, the form slit 1109 is provided in one wall section 1107W.

[0083] (Configuration of the identity verification device 1100B4 in modified example 4 of Embodiment 2) Figure 23 is a perspective view showing the identity verification device 1100B4 included in the automated cash transaction device 1000B according to the modified example 3 of Embodiment 2. Figure 24 is a cross-sectional view showing the identity verification device 1100B4 included in the automated cash transaction device 1000B according to the modified example 3 of Embodiment 2.

[0084] The identity verification device 1100B4 according to Modification 4 differs from the identity verification device 1100B in that it is provided with wall sections 1107W4 equipped with second illuminations 1107 at both ends in the Y-axis direction. The wall section 1107W4 has a lower height in the Z-axis direction compared to the wall section 1107W of the conventional identity verification device 1100. By placing the document 1004 on the identity verification device 1100B4 so that it spans the wall section 1107W4 compared to the wall section 1107W of the conventional identity verification device 1100, the focal point of the document imaging unit 1103 is positioned closer to the document 1004. That is, the code image written on the document 1004 is brought closer to the reading surface 1102 at a predetermined distance or less. Therefore, the identity verification device 1100B4 can read the code image written on the document 1004 with high accuracy.
