Description

The present invention relates to a media handling device and an automated teller machine.

In recent years, various techniques have been known as techniques for printing on a medium. For example, a technique of printing on a medium with a thermal head is known. The thermal head prints by applying an energizing pulse to the heating element. However, as the printing is repeated, the resistance value of the resistance element constituting the heating element increases (that is, the amount of heat generated by the heating element decreases), and the heating element may not perform printing normally. Therefore, a technique for early detection of a time when printing by the heating element is not normally performed (life time of the thermal head) based on the current value of the heating element is disclosed (see, for example, Patent Document 1).

The data acquisition unit acquires a fourth shading value obtained from the mark region of the second medium at startup, and the first condition is the third shading value and the fourth shading value. It may include a third condition that the difference between the two belongs to the third range.

When it is determined that the difference between the first shading value and the second shading value does not belong to the first range, the medium handling device executes a predetermined abnormal operation. May be provided.

The predetermined abnormal operation may include an operation of controlling the transport unit so that the first medium is transported to a predetermined region by the transport unit.

The first shading value is obtained based on the data detected by the sensor from the detection range when at least a part of the margin region of the first medium falls within the detection range of the sensor, and the second The shading value may be obtained based on the data detected by the sensor from the detection range when at least a part of the mark region of the first medium falls within the detection range of the sensor.

The data acquisition unit acquires the current values of each of the plurality of heating elements of the thermal head, and the processing execution unit has the difference between the first shading value and the second shading value in the first range. When the current value of at least a part of the plurality of heating elements satisfies the abnormality condition, the predetermined operation at the time of abnormality may be executed.

The abnormal condition is a condition that the current value of any one of the plurality of heating elements does not belong to the normal range, or a condition that the current value of each of two or more consecutive heating elements does not belong to the normal range. May include.

(1-2. Internal configuration of automated teller machines)
FIG. 2 is a diagram showing an example of the internal configuration of the automated teller machine 1. As shown in FIG. 2, the automatic teller machine 1 includes a banknote deposit / withdrawal machine 10, and the banknote deposit / withdrawal machine 10 has a control unit 12. The control unit 12 controls each unit (banknote deposit / withdrawal unit 16, transport unit 24, discrimination unit 18, temporary holding unit 20, recycling storage 26, reject storage 28, and forgotten storage 22).

The control unit 12 is mainly composed of a CPU (not shown), and controls each unit by reading a predetermined program from a storage unit 14 composed of a ROM, a RAM, a hard disk drive, a flash memory, or the like and executing the program. Performs various processes such as deposit transactions and withdrawal transactions.

Inside the banknote deposit / withdrawal machine 10, a banknote deposit / withdrawal unit 16 is provided on the upper side, and a discrimination unit 18 for determining the denomination and authenticity of the banknote is provided to temporarily hold the deposited banknotes and the like. A unit 20 and the like are provided.

The bill deposit / withdrawal unit 16 separates the bills inserted from the customer one by one and delivers them to the transport unit 24. Further, the bill deposit / withdrawal unit 16 separates and holds the bill to be sent out to the transport unit 24 and the bill returned to the bill deposit / withdrawal unit 16 as a deposit reject bill. Further, the bill deposit / withdrawal unit 16 is provided with a bill detection sensor (not shown) that detects whether or not there is a bill to be delivered to the transport unit 24 inside the bill deposit / withdrawal unit 16.

The transport unit 24 transports rectangular banknotes in the lateral direction along the transport path indicated by the thick line in the figure by means of a roller or a belt (neither of which is shown). The transport unit 24 transports banknotes so that the discriminating unit 18 is inserted in the front-rear direction, and connects the rear side of the discriminating unit 18, the temporary holding unit 20, and the bill deposit / withdrawal unit 16, respectively. Further, the transport unit 24 connects the front side of the discrimination unit 18, the bill deposit / withdrawal unit 16, the recycling storage 26, the reject storage 28, and the forgotten storage 22. A selector (not shown) is provided at the branch point of the transport unit 24, and the selector (not shown) rotates under the control of the control unit 12 to switch the transport destination of banknotes.

The discrimination unit 18 discriminates the denomination and authenticity of the bill, the degree of damage, etc. (correct loss) using an optical element, a magnetic detector, or the like while transporting the bill inside the bill, and determines the discrimination result. Notify the control unit 12. The discrimination result is stored in the storage unit 14 as transaction information together with the customer information according to the control by the control unit 12. Then, the destination of the bill is changed according to the discrimination result.

The temporary holding unit 20 temporarily holds the depositable banknotes that are inserted into the banknote deposit / withdrawal unit 16 by the customer at the time of deposit and are identified as depositable by the identification unit 18 until the payment is confirmed. On the other hand, the deposit rejected banknotes identified as non-depositable by the discrimination unit 18 are discharged to the banknote deposit / withdrawal unit 16 without being held by the temporary holding unit 20. In addition, the temporary holding unit 20 temporarily holds the withdrawal rejected banknotes that are determined by the identification unit 18 to be unwithdrawable at the time of withdrawal until the withdrawable banknotes are withdrawn, and then the withdrawal is made. The gold reject banknotes are discharged to the reject storage 28.

Inside the banknote deposit / withdrawal machine 10, there is a denomination recycling box 26 on the lower side, banknotes identified as banknotes damaged by the discrimination unit 18 (so-called loss tickets), banknotes determined to be counterfeit, and 5,000 banknotes. There is provided a reject storage 28 for storing banknotes of denominations that are not returned, such as 2,000 bills, and a forgotten storage 22 for collecting and storing banknotes that the customer has forgotten to take from the banknote deposit / withdrawal unit 16 at the time of transaction. .. The recycling storage 26 takes in and stores the banknotes transported from the transport unit 24 by the storage / discharge mechanism, and discharges the stored banknotes and supplies the stored banknotes to the transport unit 24.

In such a configuration, in the automatic teller machine 1, the main control unit 9 and the control unit 12 control each unit based on the result of discrimination of banknotes by the discrimination unit 18, and perform deposit processing and withdrawal processing of banknotes. That is, in the automatic teller machine 1, when a customer selects a deposit transaction via the operation display unit 6 at the time of a deposit transaction and a bill is further inserted into the deposit / withdrawal port 5, the inserted bill is inserted into the bill deposit / withdrawal unit 16. To the discrimination unit 18 one by one.

Here, the automated teller machine 1 transports the depositable banknotes determined by the discrimination unit 18 to be depositable to the temporary holding unit 20 and temporarily stores them. On the other hand, the automatic teller machine 1 returns the deposit reject bills determined to be unsuitable for deposit to the bill deposit / withdrawal unit 16 and returns them to the customer by opening the shutter. After that, when the deposit amount is confirmed by the customer, the automatic teller machine 1 transports the banknotes stored in the temporary holding unit 20 to the discrimination unit 18 and obtains the discrimination result. Here, the automated teller machine 1 transports and stores the banknotes determined to be storable based on the discrimination result of the discrimination unit 18 to each recycling storage 26 according to the denomination. On the other hand, the automated teller machine 1 transports the banknotes determined to be unsuitable for storage to the reject storage 28.

(1-3. Configuration of statement slip issuing device)
FIG. 3 is a diagram showing an example of the functional configuration of the statement slip issuing device 40A. As shown in FIG. 3, the statement slip issuing device 40A includes a control unit 100A, a transport unit 42, a thermal head 43, a cutter unit 44, and sensors 45-1 to 45-5. In the first embodiment of the present invention, it is mainly assumed that the statement slip issuing device 40A has five sensors 45. However, the number of sensors 45 included in the statement slip issuing device 40A is not limited to 5, and may be 4 or less, or 6 or more.

The control unit 100A is mainly composed of a CPU (Central Processing Unit) (not shown), and is a ROM (Read).
By reading a predetermined program from a memory such as (Only Memory) and executing it, each part of the statement slip issuing device 40A is controlled. The control unit 100A includes a data acquisition unit 120A, a determination unit 130A, and a processing execution unit 140. The functions of the data acquisition unit 120A, the determination unit 130A, and the processing execution unit 140 will be described in detail later. In addition, the functions of the transport unit 42, the thermal head 43, the cutter unit 44, and the sensors 45-1 to 45-5 will be described with reference to FIG.

FIG. 4 is a diagram showing an installation example of each part of the statement slip issuing device 40A. Referring to FIG. 4, the statement slip issuing device 40A includes a transport unit 42, a thermal head 43, a cutter unit 44, and a sensor 45 (sensors 45-1 to 45-5), as in the example shown in FIG. Has. In addition, a medium 41, a storage unit 47, and a transport path 48 are provided inside the statement slip issuing device 40A. Further, referring to FIG. 4, a detail slip discharge port 8 from which the detail slip issued by the detail slip issuing device 40A is discharged is shown.

The medium 41 can function as printing paper. As shown in FIG. 4, the medium 41 is provided inside the statement slip issuing device 40A in a rolled state, and is taken out by the transport unit 42 when the statement slip is issued. In the embodiment of the present invention, it is mainly assumed that the medium 41 is a thermal paper. In such a case, when the thermal paper senses the heat generated by the thermal head 43, the color of the thermal paper changes to perform printing. However, as will be described later, when another method is used as the printing method, the medium 41 does not have to be thermal paper.

In the following description, the medium 41 used at the time of starting the automatic teller machine 1 may correspond to the second medium. Further, the medium 41 used at the time of trading of the automatic teller machine 1 may correspond to the first medium.

The transport unit 42 has a function of transporting the medium 41. For example, the transport unit 42 includes not only a drive motor but also a pair of rollers and the like. Then, when the drive motor is driven according to the drive control by the control unit 100A, the roller pair is rotated by the drive by the drive motor, so that the medium 41 gripped by the roller pair is conveyed on the transport path 48. In the embodiment of the present invention, as shown in FIG. 4, it is mainly assumed that the transport unit 42 has two pairs of rollers, but the number of roller pairs that the transport unit 42 has is not limited.

The thermal head 43 corresponds to an example of a print head that prints on the medium 41. As described above, in the embodiment of the present invention, it is assumed that the thermal head 43 prints by changing the color of the thermal paper due to heat generation. However, the printing method is not limited to such an example. For example, a thermal transfer ink ribbon that is melted by the heat generated by the thermal head 43 may be used for printing. Alternatively, a printing method in which liquid ink is sprayed from the print head may be used.

The cutter portion 44 cuts the medium 41. More specifically, in the cutter portion 44, the medium 41 in a rolled state is taken out by the conveying portion 42, and the thermal head 43 prints in the end region of the medium 41 on the detail sheet discharge port 8 side. Then, the medium 41 is cut so that the end region is separated from the medium 41. For example, when the transaction content is printed on the end area and separated from the medium 41, the end area is discharged as a statement slip (medium) from the statement slip discharge port 8 and received by the user.

The sensor 45 detects data (sensing data) by sensing the detection range (detectable range). The type of the sensor 45 is not limited, but in the embodiment of the present invention, it is assumed that the sensor 45 is configured to include a reflection sensor. According to such a configuration, the sensor 45 can be provided at a lower cost as compared with the case where the camera is used as the sensor 45 (that is, the price of the statement slip issuing device 40A and the automatic teller machine 1 can be suppressed. become).

The reflection sensor has a light emitting unit that emits light and a light receiving unit that receives the reflected light of the light emitted by the light emitting unit. At this time, the sensor 45 detects data based on the reflected light received by the light receiving unit. In the embodiment of the present invention, it is assumed that the light emitting unit is composed of a blue LED (Light Emitting Diode). However, the light emitting unit is not limited to the case where it is composed of a blue LED. For example, the light emitting unit may be composed of an LED that emits visible light of a color other than blue. Alternatively, the light emitting unit may be configured to emit light other than visible light (for example, infrared light).

The storage unit 47 functions as an example of a predetermined area for storing the medium. In the embodiment of the present invention, it is mainly assumed that the storage unit 47 is provided at a position branched from the transport path 48 between the specification slip discharge port 8 and the sensor 45. However, the position where the storage unit 47 is provided is not limited. Details of the storage unit 47 will be described later.

The transport path 48 corresponds to the road surface on which the medium is transported.

The configuration of the automated teller machine 1 according to the first embodiment of the present invention has been described above.

(1-4. Operation at startup)
Subsequently, the operation of the statement slip issuing device 40A of the automatic teller machine 1 will be described. First, the operation of the statement slip issuing device 40A at the time of starting the automatic teller machine 1 will be described. FIG. 5 is a plan view showing an example of a transport path 48 when the automated teller machine 1 is activated. With reference to FIG. 5, the transport path 48 is shown. More specifically, the transport path 48 is oriented such that the statement sheet discharge port 8 is located above the paper surface and the thermal head 43 is located below the paper surface. Further, FIG. 5 shows a medium 41 that is transported on the transport path 48 when the automatic teller machine 1 is activated.

The sensors 45-1 to 45-5 are provided so as to be arranged in a direction perpendicular to the transport direction of the medium 41 in the transport path 48. As a result, the sensors 45-1 to 45-5 can efficiently perform sensing on the medium 41. However, the arrangement direction of the sensors 45-1 to 45-5 is not limited. Further, as shown in FIG. 5, it is desirable that the sensors 45-1 to 45-5 are arranged at substantially equal intervals so that the bias of the sensing position with respect to the medium 41 is reduced. Although the sensors 45-1 to 45-5 are shown to be directly visible in FIG. 5, in reality (as shown in FIG. 4), the sensors 45-1 to 45-5 are shown. Since it is arranged on the lower surface of the guide existing on the upper side of the transport path 48, it is not directly visible (the same applies to FIGS. 7, 10 and 12).

FIG. 6 is a flowchart showing an operation example of the statement slip issuing device 40A when the automatic teller machine 1 is activated. The operation of the statement slip issuing device 40A at the time of starting the automatic teller machine 1 will be further described with reference to FIGS. 5 and 6 (see other figures as appropriate).

The control unit 100A of the statement slip issuing device 40A shifts the operation to S11 until it receives a notification from the main control unit 9 indicating that the automatic teller machine 1 has been activated (“No” in S11). On the other hand, when the control unit 100A of the statement slip issuing device 40A receives a notification from the main control unit 9 indicating that the automatic teller machine 1 has been activated (“Yes” in S11), the medium 41 is moved by the transport unit 42. The transport unit 42 is controlled so that it is transported toward the statement slip discharge port 8.

Then, the control unit 100A controls the thermal head 43 so as to print the mark area 61 (S12). More specifically, when the medium detection sensor (not shown) detects that the position where the mark area 61 on the medium 41 should be printed has reached the printable position by the thermal head 43, the control unit 100A determines the medium. The thermal head 43 is controlled so that the mark area 61 is printed on the 41. FIG. 5 shows a state in which the mark area 61 has already been printed in this way.

The mark area 61 is a print area of the medium 41 that passes through the detection range of each of the sensors 45-1 to 45-5. The size, shape, position, etc. of the mark area 61 are not limited. However, it is necessary to determine the size, shape, position, etc. of the mark area 61 so that at least a part of the mark area 61 fits in the detection range of each of the sensors 45-1 to 45-5. For example, as shown in FIG. 5, the mark area 61 may be printed on the medium 41 so as to be a rectangular area long in the arrangement direction of the sensors 45-1 to 45-5.

Further, in the embodiment of the present invention, it is mainly assumed that the print pattern of the mark for determining the front and back of the medium is also used for the print pattern of the mark area 61. As a result, the print pattern can be used efficiently. However, the print pattern of the mark area 61 may be a specially prepared print pattern. In the front / back determination of the medium, when the front / back determination mark is not detected by the sensors 45-1 to 45-5 even though the front / back determination mark should be detected, the medium is determined. It is judged that it was installed upside down.

Subsequently, the medium 41 was further conveyed from the state shown in FIG. 5, and the medium 41 reached a position where at least a part of the mark area 61 of the medium 41 fits in the detection range of each of the sensors 45-1 to 45-5. Suppose that it is in a state. When such a state is detected by the medium detection sensor (not shown), the control unit 100A controls each of the sensors 45-1 to 45-5 so that the data (sensor data) is detected from each detection range. .. The data acquisition unit 120A measures the shading value A1 (fourth shading value) of each detection range of the mark region 61 based on each sensor data (S13). As a result, the data acquisition unit 120A obtains the shade value A1 of each detection range of the mark area 61.

The method of measuring the shading value from the sensor data is not limited. For example, the data acquisition unit 120A may measure the shading value based on the voltage level of the sensor data. At this time, the correspondence between the voltage level and the shading value is not limited. As an example, the data acquisition unit 120A may obtain a value indicating a lower density (strong whiteness) as a shade value as the voltage level of the sensor data is higher, and the data acquisition unit 120A may obtain a value indicating a lower density (strong whiteness) as a shade value, or the lower the voltage level of the sensor data, the higher the density. A value indicating the value (strong blackness) may be obtained as a shading value.

The medium 41 is further conveyed, and the medium 41 reaches a position where at least a part of the margin area 67 (that is, the unprinted area) of the medium 41 fits in the detection range of each of the sensors 45-1 to 45-5. Suppose that it became. When such a state is detected by the medium detection sensor (not shown), the control unit 100A controls each of the sensors 45-1 to 45-5 so that the data (sensor data) is detected from each detection range. .. The data acquisition unit 120A measures the shading value B1 (third shading value) of each detection range in the margin region 67 based on each sensor data (S14). As a result, the data acquisition unit 120A obtains the shade value B1 of each detection range in the margin region 67.

It is assumed that the shade value B1 obtained from the margin region 67 can change depending on the medium or sensor used at that time. Therefore, in the embodiment of the present invention, it is assumed that the shade value B1 obtained from the margin region 67 is also used for calibration. By such calibration, the shading value can be corrected appropriately. However, the margin area 67 does not have to be the area used for calibration.

The determination unit 130A determines whether or not the shade value B1 obtained from the margin region 67 satisfies a certain condition. By such a determination, it can be confirmed whether or not the medium 41 at the time of startup is normal.

Here, the condition determined by the determination unit 130A corresponds to the difference between the shade value A1 obtained from the mark area 61 and the shade value B1 obtained from the margin area 67 for each of the sensors 45-1 to 45-5. It is assumed that | A1-B1 | includes the condition that it belongs to a certain range (third range). Thereby, it can be confirmed whether or not the printing on the medium 41 and the medium 41 at the time of startup is normal. For example, when the printing on the medium 41 is not normal, the case where the mark area 61 is not printed or the case where the mark area 61 is lightly printed may be included. However, the conditions determined by the determination unit 130A are not limited to such an example.

Here, it is assumed that the range (third range) in which | A1-B1 | should be contained is a range larger than the lower limit value Th1 and smaller than the upper limit value Th2. However, the range in which | A1-B1 | should be contained (third range) may be simply a range larger than the lower limit value Th1 or simply a range smaller than the upper limit value Th2. However, considering that A1 is a shading value obtained from the mark region 61 and B1 is a shading value obtained from the margin region 67, | A1-B1 | needs to have a certain size or more. It is considered that the lower limit value Th1 is more important than the upper limit value Th2.

The determination unit 130A determines for each of the sensors 45-1 to 45-5 whether or not the condition that | A1-B1 | is larger than the lower limit value Th1 and smaller than the upper limit value Th2 is satisfied (S15). When the processing execution unit 140 determines that | A1-B1 | is the lower limit value Th1 or less or the upper limit value Th2 or more for at least a part of the sensors 45-1 to 45-5 ("No" in S15). ), Outputs a determination result indicating an abnormality (S16). On the other hand, when it is determined that | A1-B1 | is larger than the lower limit value Th1 and smaller than the upper limit value Th2 for each of the sensors 45-1 to 45-5, the processing execution unit 140 is normal (“Yes” in S15). The determination result indicating the above is output (S17).

For example, the determination result output by the processing execution unit 140 may be input to the main control unit 9. In such a case, the main control unit 9 may control the operation display unit 6 so that the determination result is displayed. Thereby, the staff or the maintenance staff can confirm whether or not the printing on the medium 41 and the medium 41 at the time of startup is normal by observing the determination result displayed by the operation display unit 6. For example, if the determination result is abnormal, the staff or the maintenance staff can take a predetermined measure (for example, replacement of the medium 41) to normalize the determination result.

The cutting position 62 is a position where the medium 41 is cut by the cutter portion 44. When the medium 41 is cut by the cutter portion 44 at the cutting position 62, a region (end region) of the medium 41 on the tip side of the cutting position 62 is separated as a medium 63 having the same size as one statement slip. .. It is desirable that the cutting position 62 is provided with continuous slits (perforations) so that the medium 41 can be easily cut by the cutter portion 44.

The medium 63 separated in this way is conveyed by the conveying unit 42 and discharged from the statement slip discharge port 8 (S18). Then, a staff member, a maintenance staff member, or the like receives the medium 63 discharged from the statement slip discharge port 8. Thereby, the staff or the maintenance staff can confirm whether or not the printing on the medium 41 and the medium 41 at the time of startup is normal by directly looking at the medium 63.

(1-5. Operation during trading)
Subsequently, the operation of the statement slip issuing device 40A at the time of transaction of the automatic teller machine 1 will be described. FIG. 7 is a plan view showing an example of a transport path 48 at the time of trading of the automated teller machine 1. With reference to FIG. 7, the transport path 48 is shown as in FIG. Further, FIG. 7 shows a medium 41 that is transported on the transport path 48 during the transaction of the automated teller machine 1, as in the example shown in FIG. Further, sensors 45-1 to 45-5 are provided as in the example shown in FIG.

FIG. 8 is a flowchart showing an operation example of the statement slip issuing device 40A at the time of transaction of the automatic teller machine 1. The operation of the statement slip issuing device 40A at the time of transaction of the automatic teller machine 1 will be further described with reference to FIGS. 7 and 8 (see other figures as appropriate).

The control unit 100A of the statement slip issuing device 40A shifts the operation to S21 until the automatic teller machine 1 receives a notification from the main control unit 9 indicating that the transaction has been executed (“No” in S21). On the other hand, when the control unit 100A of the statement slip issuing device 40A receives a notification from the main control unit 9 indicating that the automatic teller machine 1 has executed the transaction (“Yes” in S21), the medium is transmitted by the transport unit 42. The transport unit 42 is controlled so that the 41 is transported toward the statement slip discharge port 8.

Then, the control unit 100A controls the thermal head 43 so as to print the mark area 64 (S22). More specifically, when the medium detection sensor (not shown) detects that the position where the mark area 64 on the medium 41 should be printed has reached the printable position by the thermal head 43, the control unit 100A determines the medium. The thermal head 43 is controlled so that the mark area 64 is printed on the 41. FIG. 7 shows a state in which the mark area 64 has already been printed in this way.

The mark area 64 is a print area of the medium 41 that passes through the detection range of each of the sensors 45-1 to 45-5. The size, shape, position, etc. of the mark area 64 are not limited. For example, similarly to the mark area 61 (FIG. 5) printed at startup, the mark area 64 may be printed on the medium 41 so as to be a rectangular area long in the arrangement direction of the sensors 45-1 to 45-5. .. However, at the time of transaction, it is necessary to secure an area (transaction print area 65) on which the transaction content is printed. Therefore, as shown in FIG. 7, the mark area 64 is the mark area 61 (FIG. It is desirable that the rectangular area is more elongated than 5).

After that, the control unit 100A controls the thermal head 43 so as to print the transaction content inside the transaction print area 65 (S23). More specifically, when the medium detection sensor (not shown) detects that the transaction print area 65 has reached the printable position by the thermal head 43, the control unit 100A has the transaction content inside the transaction print area 65. The thermal head 43 is controlled so that printing is performed. FIG. 7 shows a state in which the transaction details have already been printed in this way.

Subsequently, the medium 41 was further conveyed from the state shown in FIG. 7, and the medium 41 reached a position where at least a part of the mark area 64 of the medium 41 fits in the detection range of each of the sensors 45-1 to 45-5. Suppose that it is in a state. When such a state is detected by the medium detection sensor (not shown), the control unit 100A controls each of the sensors 45-1 to 45-5 so that the data (sensor data) is detected from each detection range. .. The data acquisition unit 120A measures the shading value A2 (second shading value) of each detection range in the mark region 64 based on each sensor data (S24). As a result, the data acquisition unit 120A obtains the shade value A2 of each detection range in the mark area 64.

It is assumed that the medium 41 is further conveyed, and the medium 41 reaches a position where at least a part of the margin region 68 of the medium 41 fits in the detection range of each of the sensors 45-1 to 45-5. When such a state is detected by the medium detection sensor (not shown), the control unit 100A controls each of the sensors 45-1 to 45-5 so that the data (sensor data) is detected from each detection range. .. The data acquisition unit 120A measures the shading value B2 (first shading value) of each detection range in the margin region 68 based on each sensor data (S25). As a result, the data acquisition unit 120A obtains the shade value B2 of each detection range in the margin region 68.

The determination unit 130A has | A2-B2 | corresponding to the difference between the shading value A2 obtained from the mark area 64 and the shading value B2 obtained from the margin area 68 for each of the sensors 45-1 to 45-5. Determine whether or not it belongs to the range (first range). Thereby, it can be confirmed whether or not the printing on the medium 41 and the medium 41 at the time of transaction is normal. For example, when the printing on the medium 41 is not normal, the case where the mark area 64 is not printed, the case where the mark area 64 is printed lightly, and the like may be included.

Here, it is assumed that the range (first range) in which | A2-B2 | should be contained is larger than the lower limit value Th3 and smaller than the upper limit value Th4. However, the range in which | A2-B2 | should be contained (first range) may be simply a range larger than the lower limit value Th3, or may be simply a range smaller than the upper limit value Th4. However, considering that A2 is a shading value obtained from the mark area 64 and B2 is a shading value obtained from the margin area 68, | A2-B2 | needs to have a certain size or more. It is considered that the lower limit value Th3 is more important than the upper limit value Th4.

The determination unit 130A determines for each of the sensors 45-1 to 45-5 whether or not the condition that | A2-B2 | is larger than the lower limit value Th3 and smaller than the upper limit value Th4 is satisfied (S26). When the processing execution unit 140 determines that | A2-B2 | is the lower limit value Th3 or less or the upper limit value Th4 or more for at least a part of the sensors 45-1 to 45-5 (“No” in S26). ), The operation is shifted to S27. On the other hand, when the processing execution unit 140 determines that | A2-B2 | is larger than the lower limit value Th3 and smaller than the upper limit value Th4 for each of the sensors 45-1 to 45-5 (“Yes” in S26), S29 Move the operation to.

Further, the determination unit 130A has a range | B1-B2 | corresponding to the difference between the shade value B1 obtained from the margin region 67 (FIG. 5) at the time of activation and the shade value B2 obtained from the margin region 68 in S25. Determine whether or not it belongs to (second range). Thereby, it can be confirmed whether or not there is an abnormality in either the medium 41 at the time of activation or the medium 41 at the time of transaction. For example, when the medium 41 is exchanged for another set between the time of startup and the time of transaction, there may be an abnormality in either the medium 41 at the time of startup or the medium 41 at the time of transaction. It is assumed that the cause of the abnormality of the medium 41 is dirt on the medium 41 due to aged deterioration or the like.

Here, it is assumed that the range (second range) in which | B1-B2 | should be contained is a range larger than the lower limit value Th5 and smaller than the upper limit value Th6. However, the range in which | B1-B2 | should be contained (the second range) may be simply a range larger than the lower limit value Th5, or may be simply a range smaller than the upper limit value Th6. However, considering that B1 is a shading value obtained from the margin region 67 and B2 is a shading value obtained from the margin region 68, | B1-B2 | needs to be smaller to some extent, so the lower limit value Th5 It is considered that the upper limit value Th6 is more important than the above.

The determination unit 130A determines for each of the sensors 45-1 to 45-5 whether or not the condition that | B1-B2 | is larger than the lower limit value Th5 and smaller than the upper limit value Th6 is satisfied (S28). When the processing execution unit 140 determines that | B1-B2 | is the lower limit value Th5 or less or the upper limit value Th6 or more for at least a part of the sensors 45-1 to 45-5 (“No” in S29). ), The operation is shifted to S27. On the other hand, when the processing execution unit 140 determines that | B1-B2 | is larger than the lower limit value Th5 and smaller than the upper limit value Th6 for each of the sensors 45-1 to 45-5 (“Yes” in S29), S30. Move the operation to.

When the operation is shifted to S27, when the medium 41 is cut by the cutter portion 44 at the cutting position 62, the region (end region) of the medium 41 on the tip side of the cutting position 62 is one. It is separated as a medium 66 having the same size as the vote. Then, the processing execution unit 140 executes a predetermined operation at the time of abnormality.

In the embodiment of the present invention, it is assumed that the operation at the time of abnormality includes an operation of controlling the transport unit 42 so that the medium 66 thus separated is transported to the storage unit 47 by the transport unit 42. As a result, the user is not provided with the abnormal medium 66. However, the operation at the time of abnormality is not particularly limited. The medium 66 transported to the storage unit 47 by the transport unit 42 is stored in the storage unit 47. The storage unit 47 is merely an example of a region (predetermined region) of the transport destination of the medium 66 in the abnormal operation, and the transport destination of the medium 66 is not limited.

Then, the processing execution unit 140 outputs a determination result indicating an abnormality (S28). For example, the determination result indicating the abnormality output by the processing execution unit 140 may be input to the main control unit 9. In such a case, the main control unit 9 may control the operation display unit 6 so that it is displayed that the detailed slip is not discharged. As a result, the user can grasp that the statement slip is not discharged.

On the other hand, when the operation is shifted to S30, when the medium 41 is cut by the cutter portion 44 at the cutting position 62, one region (end region) of the medium 41 on the tip side of the cutting position 62 is formed. It is separated as a medium 66 having the same size as the statement slip of. The medium 66 separated in this way is discharged as a detailed slip from the detailed slip discharge port 8 (S30). Then, the user receives the statement slip discharged from the statement slip discharge port 8. This allows the user to confirm the transaction details by looking at the statement slip.

As described above, according to the first embodiment of the present invention, the determination unit 130A corresponds to the difference between the shade value A2 obtained from the mark region 64 and the shade value B2 obtained from the margin region 68. | A2-B2 | Determines whether or not it belongs to a certain range (first range). Thereby, it can be confirmed whether or not the printing on the medium 41 and the medium 41 at the time of transaction is normal. Therefore, it is possible to more accurately detect the deterioration of the print quality on the medium 41.

Further, as described above, the sensor 45 for obtaining the shading value A2 and the shading value B2 may be configured to include the reflection sensor. According to such a configuration, the sensor 45 can be provided at a lower cost as compared with the case where the camera is used as the sensor 45 (that is, the price of the statement slip issuing device 40A and the automatic teller machine 1 can be suppressed. become).

(2. Second embodiment)
Subsequently, a second embodiment of the present invention will be described. In the second embodiment of the present invention, the specification slip issuing device 40A (FIG. 3) is replaced with the specification slip issuing device 40B (FIG. 9) as compared with the first embodiment of the present invention. Therefore, in the second embodiment of the present invention, among the automated teller machines 1, the statement slip issuing device 40B will be mainly described, and the description of other configurations will be omitted.

(2-1. Configuration of statement slip issuing device)
FIG. 9 is a diagram showing an example of the functional configuration of the statement slip issuing device 40B. As shown in FIG. 9, the statement slip issuing device 40B includes a control unit 100B, a transport unit 42, a thermal head 43, a cutter unit 44, and a sensor 45-1. The statement issuing device 40B has only a small number of sensors 45 as compared with the statement issuing device 40A according to the first embodiment of the present invention. In the second embodiment of the present invention, it is mainly assumed that the statement slip issuing device 40B has only one sensor 45. However, the number of sensors 45 included in the statement slip issuing device 40B is not particularly limited.

The control unit 100B includes a data acquisition unit 120B, a determination unit 130B, and a processing execution unit 140. That is, in the control unit 100B, the data acquisition unit 120A is replaced with the data acquisition unit 120B and the determination unit 130A is replaced with the determination unit 130B as compared with the control unit 100A according to the first embodiment of the present invention. .. Therefore, in the second embodiment of the present invention, among the control units 100B, the data acquisition unit 120B and the determination unit 130B will be mainly described, and the detailed description of the processing execution unit 140 will be omitted.

(2-2. Operation at startup)
Subsequently, the operation of the statement slip issuing device 40B will be described. First, the operation of the statement slip issuing device 40B at the time of starting the automatic teller machine 1 will be described. FIG. 10 is a plan view showing an example of a transport path 48 when the automated teller machine 1 is activated. With reference to FIG. 10, the transport path 48 is shown. Further, FIG. 10 shows a medium 41 that is transported on the transport path 48 when the automated teller machine 1 is activated.

Further, referring to FIG. 10, only one sensor 45 (sensor 45-1) is provided. That is, in the second embodiment of the present invention, there are only a small number of sensors 45 (for reasons such as suppressing the price of the sensor 45) as compared with the statement slip issuing device 40A according to the first embodiment of the present invention. Not provided. In such a case, since the sensor 45 senses only a small part of the medium 41, the shading value of the medium 41 can be obtained only partially. Therefore, in the second embodiment of the present invention, in addition to the data detected by the sensor 45, the current value of the heating element group included in the thermal head 43 is used.

In the second embodiment of the present invention, as shown in FIG. 10, one sensor 45 (at a position where sensing can be performed on the central portion of the medium 41 transported along the transport path 48 ( It is mainly assumed that the sensor 45-1) is provided. However, the position where the sensor 45 (sensor 45-1) is provided is not particularly limited.

FIG. 11 is a flowchart showing an operation example of the statement slip issuing device 40B when the automatic teller machine 1 is activated. The operation of the statement slip issuing device 40B at the time of starting the automatic teller machine 1 will be further described with reference to FIGS. 10 and 11 (see other figures as appropriate).

First, S11 to S12 are executed in the same manner as S11 to S12 (FIG. 6) described in the first embodiment of the present invention.

Subsequently, it is assumed that the medium 41 is further conveyed from the state shown in FIG. 10 and the medium 41 reaches a position where at least a part of the mark area 61 of the medium 41 fits in the detection range of the sensor 45-1. .. When such a state is detected by the medium detection sensor (not shown), the control unit 100B controls the sensor 45-1 so that the data (sensor data) is detected from the detection range of the sensor 45-1. The data acquisition unit 120B measures the shading value A1 (fourth shading value) of the detection range of the mark region 61 based on the sensor data (S43). As a result, the data acquisition unit 120B obtains the shading value A1 of the detection range of the mark area 61.

It is assumed that the medium 41 is further conveyed, and the medium 41 reaches a position where at least a part of the margin region 67 of the medium 41 fits in the detection range of the sensor 45-1. When such a state is detected by the medium detection sensor (not shown), the control unit 100B controls the sensor 45-1 so that the data (sensor data) is detected from the detection range of the sensor 45-1. The data acquisition unit 120B measures the shading value B1 (third shading value) of the detection range of the margin region 67 based on the sensor data (S44). As a result, the data acquisition unit 120B obtains the shading value B1 of the detection range of the margin region 67.

The determination unit 130B determines whether or not the condition that | A1-B1 | is larger than the lower limit value Th1 and smaller than the upper limit value Th2 is satisfied (S45). When it is determined that | A1-B1 | is the lower limit value Th1 or less or the upper limit value Th2 or more (“No” in S45), the processing execution unit 140 shifts the operation to S16. On the other hand, when it is determined that | A1-B1 | is larger than the lower limit value Th1 and smaller than the upper limit value Th2 (“Yes” in S45), the processing execution unit 140 shifts the operation to S46.

When the operation is shifted to S46, the data acquisition unit 120B acquires the current value of each of the plurality of heating elements of the thermal head 43. Here, it is mainly assumed that the data acquisition unit 120B acquires the entire current value of the heating element group included in the thermal head 43 as the current value of each of the plurality of heating elements. However, the data acquisition unit 120B may acquire only a part of the current value of the heating element group included in the thermal head 43 as the current value of each of the plurality of heating elements.

The determination unit 130B determines whether or not the current values of the plurality of heating elements included in the thermal head 43 satisfy the abnormal condition (S46). When the current values of the plurality of heating elements of the thermal head 43 satisfy the abnormal condition (“Yes” in S46), the processing execution unit 140 shifts the operation to S16. On the other hand, when the current values of the plurality of heating elements of the thermal head 43 do not satisfy the abnormal condition (“No” in S46), the processing execution unit 140 shifts the operation to S17.

The abnormal condition may include a condition that the current value of any one of the plurality of heating elements of the thermal head 43 does not belong to the normal range. Alternatively, printing anomalies due to only one heating element may be tolerated. In such a case, the abnormal condition may include a condition that the current values of two or more consecutive heating elements among the plurality of heating elements of the thermal head 43 do not belong to the normal range.

Here, the normal range is not particularly limited. However, as described above, the normal range is a range larger than the threshold value in view of the fact that printing cannot be performed normally when the resistance value of the resistance element constituting the heating element becomes large (that is, when the current value becomes small). (That is, printing is not performed normally when the current value is equal to or less than the threshold value). Although the current value is directly used for the determination in S46, the determination unit 130B may calculate the resistance value from the current value under a constant voltage and use the calculated resistance value for the direct determination. In such a case, the normal range of the resistance value may be a range smaller than the threshold value of the resistance value (that is, when the resistance value becomes equal to or more than the threshold value, printing is not performed normally).

First, S16 to S18 are executed in the same manner as S16 to S18 (FIG. 6) described in the first embodiment of the present invention.

FIG. 13 is a flowchart showing an operation example of the statement slip issuing device 40B at the time of transaction of the automatic teller machine 1. The operation of the statement slip issuing device 40B at the time of transaction of the automatic teller machine 1 will be further described with reference to FIGS. 12 and 13 (see other figures as appropriate).

First, S21 to S23 are executed in the same manner as S21 to S23 (FIG. 8) described in the first embodiment of the present invention.

Subsequently, it is assumed that the medium 41 is further conveyed from the state shown in FIG. 12 and the medium 41 reaches a position where at least a part of the mark area 64 of the medium 41 fits in the detection range of the sensor 45-1. .. When such a state is detected by the medium detection sensor (not shown), the control unit 100B controls the sensor 45-1 so that the data (sensor data) is detected from the detection range. The data acquisition unit 120B measures the shading value A2 (second shading value) of the detection range of the mark region 64 based on the sensor data (S53). As a result, the data acquisition unit 120B obtains the shade value A2 of the detection range of the mark area 64.

It is assumed that the medium 41 is further conveyed, and the medium 41 reaches a position where at least a part of the margin region 68 of the medium 41 fits in the detection range of the sensor 45-1. When such a state is detected by the medium detection sensor (not shown), the control unit 100B controls the sensor 45-1 so that the data (sensor data) is detected from the detection range. The data acquisition unit 120B measures the shading value B2 (first shading value) of the detection range of the margin region 68 based on the sensor data (S54). As a result, the data acquisition unit 120B obtains the shade value B2 of the detection range of the margin region 68.

The determination unit 130B determines whether or not the condition that | A2-B2 | is larger than the lower limit value Th3 and smaller than the upper limit value Th4 is satisfied (S55). When it is determined that | A2-B2 | is the lower limit value Th3 or less or the upper limit value Th4 or more (“No” in S55), the processing execution unit 140 shifts the operation to S27. On the other hand, when it is determined that | A2-B2 | is larger than the lower limit value Th3 and smaller than the upper limit value Th4 (“Yes” in S55), the processing execution unit 140 shifts the operation to S56.

The determination unit 130B determines whether or not the condition that | B1-B2 | is larger than the lower limit value Th5 and smaller than the upper limit value Th6 is satisfied (S56). When it is determined that | B1-B2 | is the lower limit value Th5 or less or the upper limit value Th6 or more (“No” in S56), the processing execution unit 140 shifts the operation to S27. On the other hand, when it is determined that | B1-B2 | is larger than the lower limit value Th5 and smaller than the upper limit value Th6 (“Yes” in S56), the processing execution unit 140 shifts the operation to S46.

S46 is executed in the same manner as S46 (FIG. 11) described in the operation of the statement slip issuing device 40B when the automatic teller machine 1 is activated. Further, S27, S28, and S30 are executed in the same manner as S27, S28, and S30 (FIG. 8) described in the first embodiment of the present invention.
