The housing 4 has a main body control unit 6 and a deposit / withdrawal mechanism unit 7 for controlling each mechanism.
In the present embodiment, the automatic transaction apparatus 1 will be described on the assumption that both the user and the clerk use the same operation / display unit 5. However, depending on the type of the automatic transaction apparatus 1, the clerk operation may be performed separately from the user. A display / display unit is provided inside the housing 4 to display or input information for confirming the operation of the staff.

FIG. 2 is a control block diagram showing the control relationship of the automatic transaction apparatus 1.
The card / detail slip processing mechanism 2, the passbook processing mechanism 3, the operation / display unit 5, and the automatic transaction apparatus 1 are connected to the main body control unit 6 via the bus 20 and are necessary under the control of the main body control unit 6. Perform the action. In addition, a discrimination unit 21 for discriminating banknotes and a storage unit 22 are also connected by a bus 20 and exchange necessary data. Note that each of the mechanisms and components described above is supplied with power by the power supply unit 23.

FIG. 3 is a control block diagram showing the control relationship of the deposit / withdrawal mechanism unit 7.
A control unit 30 provided in the deposit / withdrawal mechanism unit 7 is connected to the main body control unit 6 of the automatic transaction apparatus 1 through a bus 31. The control unit 30 sends the command from the main body control unit 6 and the state of the automatic transaction apparatus 1 to the main body control unit 6 as necessary. Moreover, the control part 30 is connected with the drive motor of each function part, an electromagnetic solenoid, and a sensor, and controls drive according to transaction.

  The deposit / withdrawal mechanism unit 7 includes a deposit / withdrawal port 31 through which a user inserts / withdraws banknotes, a discrimination unit 32 that discriminates banknotes, a temporary storage 33 for temporarily storing the deposited banknotes until the transaction is established, One deposit box 34 for storing established banknotes, a reject box 37 for storing banknotes inappropriate for withdrawal, a single deposit box 38 for storing banknotes for withdrawal and a plurality of return boxes for both deposit and withdrawal 39, a conveyance path sensor for detecting the passage of banknotes and a conveyance path for conveying the banknotes to the deposit / withdrawal port 31, the temporary storage box 33, the deposit box 34, the reject box 37, the withdrawal box 38 and the reflux box 39 through the discrimination unit 32 35, and a control unit 30.

  An image pickup unit 42 is configured at the deposit / withdrawal port 31. The control unit 30 executes control of imaging timing of the imaging unit 42 and storage of image data. The captured image captured by the imaging unit 42 is analyzed by the image processing unit 43. The data of the captured image or the analysis image may be stored in the storage unit 22 of the automatic transaction apparatus 1, or may be stored in various ways, for example, temporarily stored in a non-volatile memory or stored in a hard disk for a certain period. realizable. When stored in the hard disk for a certain period, the accumulated image data can be used for analysis or the like.

FIG. 4 is a configuration diagram showing the configuration of the automatic transaction apparatus 1. Hereinafter, the depositing operation will be described.
During the depositing operation, the bills inserted into the deposit / withdrawal port 31 are transported by the transport path 41 a connected to the deposit / withdrawal port 31, taken into the automatic transaction apparatus 1, and carried to the discrimination unit 32. In the discrimination part 32, the denomination and authenticity of a banknote are determined.
The identified banknotes are temporarily stored in the temporary storage 33 through the conveyance path 41d. The medium that cannot be identified by the discrimination unit 32 is transported to the deposit / withdrawal port 7 through the transport path 41e connected to the deposit / withdrawal port 31 through the transport path 41c and returned to the user.
When all the banknotes inserted into the deposit / withdrawal port 31 are normal, the banknotes stored in the temporary storage box 33 are fed out and stored in the deposit box 34 or the return box 39, and the depositing operation is completed.

FIG. 5 is a configuration diagram of the deposit / withdrawal mechanism unit 7 mounted on the automatic transaction apparatus 1.
A shutter 51 that slides in the opening / closing direction and opens / closes the opening is provided at the opening of the deposit / withdrawal port 31. In addition, a push plate 52, a front plate 53, a roller 54, a sensor 55, a threshold plate 56, an imaging unit 42, and a banknote 100 are illustrated inside.
When separation is started, the push plate 52 and the threshold plate 56 move in the direction of the front plate 53, sandwich the bill 100 inserted by the user, and rotate the roller 54 to separate the bill 100 one by one. The sensor 55 detects the feeding of the medium from the deposit / withdrawal port 31.

  The separated banknote 100 is transported to the discrimination unit 32 by the transport path 41a, and when determined to be a normal banknote, it is transported to the temporary storage 33 and temporarily stored. When it is determined by the discrimination unit 32 that the bill is not normal, the bill is returned to the deposit / withdrawal port 31 through the transport path 41c and the transport path 41e. Moreover, the banknote 100 for withdrawing from the bank safe 38 and the return | refund box 39 is conveyed from the conveyance part 41b, and is returned to the deposit or withdrawal port 31.

  Note that the banknote 100 returned to the deposit / withdrawal port 31 is conveyed by the conveyance path 41b or the conveyance path 41e, and is an area on the side taken into the automatic transaction apparatus 1 from the deposit / withdrawal port 31 with the boundary plate 56 as a boundary. It is stored in the opposite area. Thereby, the deposited banknote and the withdrawn banknote can be stored separately. When the foreign object 101 is detected, the foreign object 101 is kept in front of the user in the deposit / withdrawal port 31 and is stored in the deposit / withdrawal port 31. The shutter 51 can be opened to prompt the user to turn it on again. However, the banknote 100 to be returned may be stored in the same area as the side taken into the automatic transaction apparatus 1 from the deposit / withdrawal port 31 with the threshold plate 56 as a boundary.

The imaging unit 42 arranges the imaging unit 42 at a position where an image of the entire surface of the medium to be separated (banknote immediately before separation) can be acquired. By capturing an image of the entire surface of the medium to be separated, foreign matter contained in the medium handling port can be reliably detected. Further, accessories (not shown) such as imaging illumination necessary for shooting are also arranged so that the imaging unit 42 can capture the banknote 100 clearly. Note that the detection accuracy may be improved by mounting a plurality of imaging units 42.
The sensor 55 detects the passage of the banknote 100 and photographs the next separated banknote 100 when the rear end of the banknote 100 being separated passes. By adjusting the imaging timing using the sensor 55, it is possible to reliably image foreign matter such as each bill 100 or a piece of paper.

FIG. 6 is a diagram illustrating an image processing flow performed by the image processing unit 43.
First, in step S <b> 601, the image processing unit 43 starts image analysis processing when receiving an instruction to start image analysis from the control unit 30. Next, in S <b> 603, the image processing unit 43 performs image acquisition and analysis from the imaging unit 42. In step S605, the presence / absence of foreign matter detection is confirmed as a result of image analysis. Here, the foreign matter refers to a medium other than banknotes. If no foreign matter is detected (S605: No), the image is acquired again and analyzed. If foreign matter detection is present (S605: Yes), foreign matter detection information is present and stored (S607).

  The above image analysis is always performed asynchronously. The image processing unit 43 first determines whether the imaged medium corresponds to any one of a plurality of types of banknotes, and then compares the corresponding RGB image distribution of the image during separation with the acquired image during separation. By doing so, it is determined whether or not there is a foreign object other than banknotes such as a receipt in the acquired image.

7A and 7B show an analysis example of an image captured by the imaging unit 42. FIG.
The horizontal axis of each graph of FIG. 7A and FIG. 7B shows a gradation, and a vertical axis | shaft shows appearance frequency.
FIG. 7A shows an RGB distribution in pixels at a predetermined position in an image in which only a normal banknote 100 is captured, and FIG. 7B shows an RGB distribution in pixels at a predetermined position in an image in which a paper piece 70 such as a receipt is captured together with the banknote 100. Indicates. When the paper piece 70 is projected together with the banknote 100, the frequency of the white component of each pixel increases as can be seen from FIGS. 7A and 7B, so that the presence of foreign matter can be detected.

FIG. 8 is a flowchart showing medium separation processing performed by the deposit / withdrawal mechanism unit 7.
When the user inserts the bill 100 into the deposit / withdrawal mechanism unit 7, the automatic transaction apparatus 1 starts separating the bill 100 of the deposit / withdrawal mechanism unit 7. The deposit / withdrawal mechanism unit 7 notifies the image processing unit 43 of the start of image processing, and stores the banknote 100 separated by rotating the roller 54 in the separating direction of the banknote 100 in the temporary storage 33 (S801).
Next, the presence / absence of a medium in the deposit / withdrawal port 31 is detected by an optical sensor disposed at the deposit / withdrawal port 31 to determine whether there is a medium that is not separated (S803).
Then, when there is no medium in the deposit / withdrawal port 31 (S803: Yes), the control unit 30 stops the roller 54, assuming that the transaction process has been completed normally (S807). When there is a medium (S803: No), the image processing unit 43 is inquired about the analysis result of the image, and it is confirmed whether or not a foreign object such as a receipt is included in the image being separated (S805).

  When no foreign matter is detected by foreign matter detection (S805: No), it is detected whether or not the end of the banknote 100 on the shutter part 51 side passes through the sensor 55, and the end of the banknote 100 passes through the sensor 55 ( (S809: Yes), the separation operation is repeated until the deposit / withdrawal port 31 becomes empty. If it has not passed (S809: No), the process returns to S803.

  When there is a foreign object by foreign object detection (S805: Yes), the roller 54 is stopped (S811). Finally, in S813, the control unit 30 displays the captured image or the edited image of the captured image on the operation / display unit 5.

  As described above, each of the media received at the deposit / withdrawal port 31 is clearly imaged by controlling the imaging of the next medium after the end of the banknote 100 passes the sensor 55, Reliable foreign object detection can be performed.

  In addition, when the automatic transaction apparatus 1 detects a foreign material, the shutter 51 of the deposit / withdrawal port 31 is opened simultaneously with the display of S813 or after the display. At this time, the shutter 51 may be opened with only the medium in the deposit / withdrawal port 31 stored, or the banknote stored in the temporary storage 33 may be returned to the deposit / withdrawal port 31 to open the shutter 51.

  Further, the medium presence / absence detection of the deposit / withdrawal port 31 performed in S803 is not an optical sensor, but is detected by, for example, comparing pixels of an image captured in the present embodiment and an image when the deposit / withdrawal port 31 is empty. May be. Thereby, even if there is a broken banknote 100 or the like not on the optical axis of the optical sensor, it can be detected, and it is detected that the banknote 100 is accidentally empty, and the trouble of cash miscalculation that the remaining banknote 100 passes to the next user is avoided. be able to.

  FIGS. 10A and 10B show examples of guidance screens displayed on the operation / display unit 5. As shown in FIG. 10 (a), the operation / display unit 5 displays a guidance for prompting the user to re-enter along with the captured image or the edited image. Further, as shown in FIG. 10 (b), by displaying together the number or amount of banknotes that are normally traded and stored in the temporary storage 33, the user's anxiety that the full amount is not returned at hand. Can also be eliminated. Furthermore, along with the above display, voice guidance such as “Receipt has been detected. Check the banknote in the deposit / withdrawal slot and re-insert” may be used.

As described above, in this embodiment, the image pickup means is provided in the deposit / withdrawal port 31, and the entire image of each medium inserted into the deposit / withdrawal port 31 is reliably acquired by using the sensor to detect the foreign matter. By doing so, it is possible to prevent the banknotes from being jammed due to abnormal conveyance without taking in foreign matter inside the automatic transaction apparatus 1. Further, since the user can confirm the operation / display unit 5 and immediately recognize and respond to the deposit error, the transaction process can be immediately resumed.
Further, the control unit 30 stores the state and behavior of the banknote 100 in the middle of separation as an image in the storage unit 22 as needed, or stores them in an external storage device or the like at the timing of the end of the transaction of the user. It can be used as a cause investigation when a failure occurs or as an evidence image after the fact.

[Second Embodiment]
In this embodiment, in particular, even if the medium deposited in the deposit / withdrawal port 31 is a banknote, even if the banknote is folded, shaken, or has an appropriate outer shape, the inserted banknote has a poor attitude. Therefore, the deposit of the banknote in the state where the outer shape is abnormal is detected. Whether or not the outer shape is abnormal is that the foreign object detection in S805 in FIG. 8 is changed to the outer shape abnormality detection, and the other steps are the same as those in FIG. In the following, the outer shape abnormality detection will be described, and description of other similar steps will be omitted.

In the present embodiment, edge detection is performed from the captured image by image processing to detect an external shape abnormality. FIG. 9 shows an example of edge detection from a captured image. The edge detection of the medium can be performed using a known technique as described in, for example, JP-A-6-251128.
FIG. 9A shows an example of edge detection of a normal banknote 100, and the number of edges is N = 4. On the other hand, FIG. 9B shows an example of edge detection of the folded banknote 100, and the number of edges is N = 5. As described above, the outer shape abnormality of the banknote 100 is detected by edge detection.

  Further, when an external shape abnormality is detected by edge detection, a guidance for prompting the user to re-enter is displayed on the operation / display unit 5 together with the captured image or the edited image as shown in FIGS. 11 (a) and 11 (b). Further, similarly to the first embodiment, the number or amount of banknotes normally traded as shown in FIG. 11B may be displayed together. Further, guidance may be displayed together with voice guidance.

  As described above, in the present embodiment, since it is possible to detect the banknote 100 having an abnormal outer shape that is broken, tilted, or torn before being separated, the banknote having an abnormal outer shape is inserted and conveyed. Therefore, it is possible to avoid a conveyance abnormality caused by this in advance. In addition, the automatic transaction apparatus 1 can continue the transaction by prompting the user to confirm through the operation / display screen 5 and correcting the posture of the banknote 100 having an abnormal outer shape.

  In addition, although the structure which arrange | positions the imaging part 42 in the deposit / withdrawal port 31 was demonstrated above, the same structure is applicable also to the temporary storage 33. FIG. Similar to the deposit / withdrawal port 31 in the temporary storage 33, if the sky is erroneously detected as having no medium, the remaining banknote 100 may be accidentally passed to the next user, resulting in a cash miscalculation failure. Therefore, the same effect can be expected when the imaging unit 42 is arranged at a position where the frontmost surface of the banknote 100 separated by the temporary storage 33 can be imaged and the separation process is performed.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to these examples, A various structure and operation | movement are applicable in the range which does not deviate from the meaning.
