  Hereinafter, embodiments will be described with reference to the drawings. First, an example of the appearance of the ATM according to the embodiment will be described with reference to FIG. The ATM 10 has a function of executing transactions such as deposit, refund, transfer, bankbook entry in response to a request from a customer (user), and an IC chip part (IC card chip part) of an IC card as described later, It has an automatic cleaning function for the read head (unit body IC contact portion) of the card reading unit and the card transport path (also simply referred to as the transport path).

  The ATM 10 includes a display unit 11 for displaying a transaction key for performing a transaction, a coin insertion slot 12 for inputting and discharging coins, a bill insertion slot 13 for inputting and discharging banknotes, an IC card, and the like. Card insertion port 14 for inserting and discharging the card and a passbook insertion port 20 for inserting and discharging the bankbook. The ATM 10 may have a configuration other than the above configuration, but the description thereof is omitted here.

  Next, an example of a card read unit that reads information of an IC card inserted from the card insertion slot 14 will be described with reference to FIG. The card read unit 21 constitutes a part of the ATM 10 and, as shown in FIG. 2, a card insertion slot 14, a card transport path 22, a transport roller 23, a card retracting section 24, a card reading section 25, roll paper. A drive motor 26, a cleaning sheet storage (part) 27, and a cleaning liquid storage (part) 28 are included. The configuration of the card lead unit 21 is not limited to this, and may include other components, but the description thereof is omitted here.

  The card transport path 22 is for transporting an IC card. For example, the card transport path 22 is transported directly under the card reading unit 25 to read information on the inserted IC card, or the IC card is returned to the customer. Therefore, it is used for transporting to the card insertion slot 14. The transport roller 23 is composed of a pair of rollers positioned above and below the surface of the card transport path 22 and sandwiches the IC card on the card transport path 22 by the pair of rollers, and transports the IC card by rotating. . In FIG. 2, only one pair of transport rollers 23 is shown, but there may be a plurality of pairs.

  The card retracting section 24 is provided on the card transport path 22 and temporarily retracts the IC card when cleaning the IC chip section of the IC card, as will be described later. Specifically, as shown in FIG. 3, the card retracting portion 24 is provided by lowering a part of the card transport path 22 via a spring or the like. When the cleaning is completed, part of the lowered card transport path 22 rises and becomes integrated with the card transport path 22.

  The card reading unit 25 includes a read head (not shown) that reads information on the IC card, and starts reading when the IC card to be conveyed is set at a reading position directly below the card reading unit 25.

  The roll paper drive motor 26 has a drive shaft (not shown). For example, the roll paper drive motor 26 feeds a cleaning sheet such as roll paper wound around a shaft on the extension of the drive shaft onto the card transport path 22 by rotation of the drive shaft. Or take it up.

  The cleaning sheet storage unit 27 stores a cleaning sheet. For example, the cleaning sheet storage unit 27 stores a cleaning sheet wound around a shaft on an extension of the drive shaft of the roll paper drive motor 26.

  The cleaning liquid storage unit 28 stores the cleaning liquid and wipes the cleaning liquid on the cleaning sheet that is fed out. The instruction for wiping the cleaning liquid is performed by the control unit 43 described below, and the control unit 43 controls whether or not the cleaning liquid is wiped and the amount of wiping of the cleaning liquid according to the contents of an error code described later. Also good. In addition, the cleaning liquid storage unit 28 does not store one type of cleaning liquid, but stores a plurality of cleaning liquids having different cleaning capacities, and uses different cleaning liquids according to the contents of error codes to be described later. Good. In this case, the use control is performed by the control unit 43.

  Next, an example of the functional configuration of the ATM according to the embodiment will be described with reference to FIG. As illustrated in FIG. 4, the ATM 10 includes a calculation unit 40, a determination unit 41, a retraction control unit 42, a control unit 43, and a storage unit 44. In addition to the above components, the ATM 10 includes components for executing transactions such as deposit, withdrawal, and transfer, but the description thereof is omitted here.

  When the IC card is inserted from the card insertion slot 14, the control unit 43 drives the transport roller 23 to transport the IC card to a predetermined reading position in order to cause the card reading unit 25 to read information on the IC card. Let At this time, before the IC card is transported to the reading position, the transport roller 23 for transporting the IC card may slip and cause an error (error due to slip). Further, when the IC card is transported to the reading position and the information of the IC card is read by the card reading unit 25, it cannot be read due to contamination of oil and grease attached to the IC chip portion of the IC card, resulting in an error. In some cases (reading errors due to IC card contamination, etc.). An error code corresponding to each case is output to the control unit 43 when an error occurs.

  An example of each error code is shown in FIGS. 5A and 5B. What is shown in FIG. 5A is a slip code that is output in the case of an error due to slip, and what is shown in FIG. 5B is a lead-out code that is output in the case of a reading error due to contamination of the IC card or the like. Each error code can be represented by a combination of four-digit alphanumeric characters.

  The output of these error codes means that the IC card information cannot be read. Therefore, the control unit 43 issues an instruction (retry instruction) to retry the reading to the transport roller 23 and the card reading unit 25 in order to try the reading of the IC card information by the card reading unit 25 again.

  The arithmetic unit 40 counts the number of times that the information on the IC card is read again, that is, the number of retry instructions, because the information on the IC card cannot be read due to a predetermined error. Here, the predetermined error is, for example, an error due to slipping of the transport roller 23 that transports the IC card, or a reading error due to contamination of the IC card by the card reading unit 25 that reads information on the IC card, as described above. .

  The determination unit 41 determines whether or not the counted number is a predetermined number or more. Here, the predetermined number of times is, for example, three times. In this example, when the retry instruction is made three times, automatic cleaning described later is performed.

  The retreat control unit 42 retreats the IC card to the card retraction unit 24 provided in the card transport path 22 when the counted number is equal to or greater than the predetermined number. Specifically, as described above, the IC card is retracted by lowering a part of the card transport path 22 or the like.

  The control unit 43 feeds the cleaning sheet stored in the cleaning sheet storage unit 27 onto the card transport path 22 so that the IC card can be brought into contact with the IC chip unit of the IC card after the IC card is retracted to the card retracting unit 24. In order to drive and control the roll paper drive motor 26 (drive unit), and after the cleaning sheet comes into contact with the IC chip part, that is, after the cleaning sheet is brought into contact with the dirty part of the IC chip part, The roll paper drive motor 26 is instructed to take up the cleaning sheet.

  The roll paper drive motor 26 rotates the drive shaft in order to store the cleaning sheet in the cleaning sheet storage unit 27 based on the instruction. As the drive shaft rotates, the cleaning sheet is wound around the shaft on the extension of the drive shaft. The control unit 43 removes the cleaning sheet from the card conveying path 22 so that the IC card can be brought into contact with not only the IC chip unit of the IC card but also the read head of the card reading unit 25 after the IC card is retracted to the card retracting unit 24. The roll paper drive motor 26 may be instructed to feed upward.

  Further, the control unit 43 drives the roll paper to repeat the operation of winding and unwinding the cleaning sheet (reciprocating operation of the cleaning sheet) while the cleaning sheet is in contact with the read head of the IC chip unit or the card reading unit 25. After the motor 26 has performed a predetermined number of times, the cleaning sheet may be wound and stored. Here, the predetermined number of reciprocating operations of the cleaning sheet may be determined according to the error code, for example, 2 times for the slip code, 3 times for the lead-out code, and the like. Thereby, about the stain | pollution | contamination difficult to wipe off, such as fats and oils, the stain | pollution | contamination difficult to wipe off can be dropped by increasing the frequency | count of wiping off. In addition, the predetermined number of reciprocation operations of the cleaning sheet may be determined according to the predetermined number used in the determination by the determination unit 41. For example, the predetermined number of reciprocating operations may be increased as the predetermined number is larger, that is, as the reading becomes difficult. As a result, it is possible to perform cleaning as carefully as it is difficult to read.

  Further, the control unit 43 controls the roll paper drive motor 26 so that the cleaning sheet is fed out onto the card conveyance path 22 when the ATM 10 is at rest (for example, when the ATM 10 is activated or at a predetermined night time). May be. Thereby, not only the IC chip part of the IC card and the read head of the card reading part 25 but also the card conveying path 22 can be cleaned.

  The cleaning sheet described above is a sheet made of one material, but is not limited to this.

  For example, as shown in FIG. 6, the cleaning sheet is composed of a front part and a rear part including the front end of the cleaning sheet along the feeding and winding directions of the cleaning sheet, and different materials (first material and first material). 2 materials). The second material of the rear part may be a material having a higher cleaning efficiency than the first material of the front part. A material having good cleaning efficiency is, for example, a material having a high contamination removal rate. In addition, in the case of a material with good cleaning efficiency, there is a possibility that the IC chip part of the IC card may be damaged such as scratches, but it is preferable to use a material that can suppress such damage. .

  In the case of the cleaning sheet as shown in FIG. 6, after the IC card is retracted to the card retracting unit 24, the control unit 43 feeds the cleaning sheet so that the front part of the cleaning sheet can come into contact with the IC chip part of the IC card. The roll paper drive motor 26 controls the roll paper drive motor 26 so as to feed out the cleaning sheet so that the subsequent stage portion of the cleaning sheet can come into contact with the IC chip portion of the IC card in accordance with the subsequent reading result of the IC card information. 26 is controlled.

  Here, according to the reading result, the cleaning sheet is fed out so that the latter part of the cleaning sheet can come into contact with the IC chip part of the IC card. For example, the cleaning part is cleaned at the former part of the cleaning sheet after one retry instruction. After cleaning, for example, when the information on the IC card cannot be read even if there are three retry instructions, the cleaning sheet is fed out so that the latter part of the cleaning sheet contacts the IC chip portion of the IC card. .

  Further, for example, as shown in FIG. 7, the cleaning sheet is made of different materials (first material and second material) on the side of the card reading unit 25 that contacts the read head and the side that contacts the IC card, The first material on the side in contact with the read head of the card reading unit 25 may be made of a material having a higher cleaning efficiency than the second material on the side in contact with the IC card. With such a configuration, it is possible to efficiently clean a read head that is used more frequently than an IC card.

  Here, an example of the process up to the end of cleaning of the IC card (IC chip unit) will be described with reference to FIGS. 8A to 8D. FIG. 8A is a diagram illustrating a state in which the IC card is retracted to the card retracting unit 24 by the retracting control unit 42. As shown in FIG. 8A, the card retracting portion 24 is retracted so that the surface of the IC chip portion of the IC card has the same or substantially the same height as the surface of the card transport path 21. Thereby, when the cleaning sheet is drawn out onto the card conveyance path 22, the cleaning sheet can come into contact with the surface of the IC chip portion and wipe the surface of the IC chip portion.

  FIG. 8B is a diagram illustrating a state in which the cleaning sheet is drawn out onto the card conveyance path 22. FIG. 8B shows the case where the cleaning liquid is wiped onto the cleaning sheet when the cleaning sheet is fed out. However, as described above, the cleaning liquid may be wiped according to the content of the error code. Good. Further, after the cleaning sheet is fed out onto the card conveyance path 22, the cleaning sheet is not simply wound up to clean the IC chip portion or the read head of the card reading portion 25. A reciprocating operation may be performed to clean the read head of the IC chip unit or the card reading unit 25.

  FIG. 8C shows a state where the cleaning sheet is wound up and stored in the cleaning sheet storage unit 27 after cleaning.

  FIG. 8D shows a state where the IC card of the card retracting unit 24 is returned to the card transport path 22 and the IC card is read again. If the reading succeeds by reading again after cleaning, the transaction can be continued without wiping the IC card or re-inserting the IC card by the customer.

  Next, an example of a hardware configuration for realizing the ATM according to the embodiment will be described with reference to FIG. The hardware configuration includes, for example, a CPU (Central Processing Unit) 91, a HDD (Hard Disk Drive) 92, a ROM (Read Only Memory) 93, a RAM (Random Access Memory) 94, a card read unit 21, and a bus 95. . The CPU 91, HDD 92, ROM 93, RAM 94, and card read unit 21 are connected to each other via a bus 95, for example.

  The CPU 91 reads a program for performing various processes of the ATM 10 stored in the HDD 92 or the like via the bus 95, temporarily stores the read program in the RAM 94, and performs various processes according to the program. , Mainly functioning as the arithmetic unit 40, the determination unit 41, the retreat control unit 42, and the control unit 43 described above.

  The HDD 92 stores application programs for performing various processing of the ATM 10, data necessary for processing of the ATM 10, and the like, and mainly functions as the storage unit 44 described above.

  The ROM 93 is a non-volatile memory and stores programs such as a boot program and BIOS (BasicInput / Output System).

The RAM 94 is a volatile memory and temporarily stores an OS (Operating System) program and a part of application programs to be executed by the CPU 91. The RAM 94 stores various data necessary for processing by the CPU 91.
The bus 95 is a path that mediates transmission / reception of control signals, data signals, and the like between the devices.

  Next, an example of the ATM automatic cleaning process according to the embodiment will be described with reference to FIG. As shown in FIG. 10, when an IC card is inserted into the card insertion slot 14, an IC card reading process is started (step S1001). It is checked whether or not a reading error has occurred (step S1002). If it does not occur (No in step S1002), the process ends. If it occurs (Yes in step S1002), the calculation unit 40 determines the number of times that the information on the IC card is read again without reading the information on the IC card due to a predetermined error, that is, the number of retry instructions. Count (step S1003). The determination unit 41 determines whether or not the counted number is a predetermined number or more (step S1004).

  If the counted number is equal to or greater than the predetermined number (Yes in step S1004), the evacuation control unit 42 causes the card evacuation unit 24 to evacuate the IC card (step S1005). If the counted number is less than the predetermined number (No in step S1004), the IC card information reading is attempted again.

  The control unit 43 feeds the cleaning sheet stored in the cleaning sheet storage unit 27 onto the card transport path 22 so that the IC card can be brought into contact with the IC chip unit of the IC card after the IC card is retracted to the card retracting unit 24. The roll paper drive motor 26 is driven and controlled, and after the cleaning sheet comes into contact with the IC chip portion, that is, after the cleaning sheet is brought into contact with the contaminated portion of the IC chip portion, the cleaning sheet is wound to wipe off the contaminated portion. The roll paper drive motor 26 is instructed to take it (step S1006). Based on this instruction, the cleaning sheet is wound up and stored in the cleaning sheet storage unit 27 (step S1007). Next, the IC card is returned (step S1008), and the process returns to step S1001 to attempt to read the IC card information after cleaning again.
