  Embodiments will be described below 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, withdrawal, transfer, passbook registration, etc. in response to a request from a customer (user), and an IC chip unit (IC card chip unit) of an IC card as described later It has an automatic cleaning function of the read head (unit contact point IC unit) of the card reading unit and the card conveyance path (also simply referred to as a conveyance path).

  The ATM 10 has a display unit 11 for displaying a transaction key and the like for conducting transactions, a coin insertion slot 12 for inserting and discharging coins, a bill insertion slot 13 for inserting and discharging bills, and an IC card etc. And a passbook insertion slot 20 for inserting and ejecting a passbook. The ATM 10 may have a configuration other than the above configuration, but the description is omitted here.

  Next, an example of a card read unit for reading 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, the card insertion slot 14, the card conveyance path 22, the conveyance roller 23, the card retraction unit 24, the card reading unit 25, roll paper It comprises a drive motor 26, a cleaning sheet storage (section) 27, and a cleaning liquid storage (section) 28. The configuration of the card read unit 21 is not limited to this, and may include other components, but the description will be omitted here.

  The card conveyance path 22 is for conveying an IC card, for example, conveys immediately below the card reading unit 25 or the like for reading information of the inserted IC card, or returns the IC card to the customer. In order to transport the card to the card insertion slot 14 for this purpose, as shown in FIG. The conveyance roller 23 is a pair of rollers positioned above and below the surface of the card conveyance path 22. The IC roller is conveyed by holding the IC card on the card conveyance path 22 with a pair of rollers and rotating the IC card. . Although only one pair of transport rollers 23 is shown in FIG. 2, there may be a plurality of pairs.

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

  The card reading unit 25 includes a read head (not shown) that reads information of 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, causes a cleaning sheet such as roll paper wound around a shaft on the extension of the drive shaft to be fed out onto the card conveyance path 22 by rotation of the drive shaft. Or take them up.

  The cleaning sheet storage unit 27 stores a cleaning sheet, and stores, for example, the cleaning sheet wound around a shaft on the 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 to be fed out. In addition, an instruction to wipe the cleaning liquid is given by the control unit 43 described below, and the presence or absence of the cleaning liquid and the amount of wiping are controlled by the control unit 43 in accordance with the content of the error code described later. It is also good. In addition, the cleaning liquid storage unit 28 stores a plurality of cleaning liquids different in cleaning ability, instead of storing one type of cleaning liquid, and uses the cleaning liquid properly depending on the content of an error code described later. Good. Control of selective use in this case 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 shown in FIG. 4, the ATM 10 includes an arithmetic unit 40, a determination unit 41, a save control unit 42, a control unit 43, and a storage unit 44. In addition, although ATM10 contains the component for performing transactions, such as deposit, refund, a transfer, etc. other than the said component, description is abbreviate | omitted here.

  When the IC card is inserted from the card insertion slot 14, the control unit 43 controls the drive of 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 of the IC card. Let At this time, before the IC card is transported to the reading position, the transport roller 23 transporting the IC card may slip to cause an error (error due to slip). In addition, when the IC card is conveyed to the reading position and the information of the IC card is read by the card reading unit 25, an error may occur because the oil or the like attached to the IC chip of the IC card can not read it. There is a case (a reading error due to contamination of the IC card). 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 readout code that is output in the case of a read error due to a dirty IC card or the like. Each error code can be represented by a combination of four alphanumeric characters.

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

  Arithmetic unit 40 counts the number of attempts to read the information on the IC card again, that is, the number of retry instructions, without reading the information on the IC card due to a predetermined error. Here, the predetermined error is, for example, an error due to a slip of the transport roller 23 for transporting the IC card or a reading error due to the contamination of the IC card by the card reading unit 25 reading the information of the IC card, as described above. .

  The determination unit 41 determines whether the counted number is equal to or more than a predetermined number. The predetermined number of times here is, for example, three times. In this example, when the retry instruction is issued three times, automatic cleaning described later is performed.

  When the counted number of times is equal to or more than the predetermined number, the retraction control unit 42 retracts the IC card in the card retraction unit 24 provided in the card conveyance path 22. Specifically, as described above, the IC card is retracted by lowering a part of the card transport path 22 or the like.

  After the IC card is retracted to the card retraction unit 24, the control unit 43 feeds the cleaning sheet stored in the cleaning sheet storage unit 27 onto the card conveyance path 22 so that it can contact the IC chip of the IC card. In order to drive and control the roll paper drive motor 26 (drive unit) and to wipe the contamination after the cleaning sheet abuts on the IC chip, that is, after the cleaning sheet is brought into contact with the contamination on the IC chip It instructs the roll paper drive motor 26 to take up the cleaning sheet.

  The roll paper drive motor 26 rotates the drive shaft to store the cleaning sheet in the cleaning sheet storage unit 27 based on the instruction. The rotation of the drive shaft causes the cleaning sheet to be wound around the shaft on the extension of the drive shaft. Note that after the IC card is retracted to the card retraction unit 24, the control unit 43 can contact the cleaning sheet to the card conveyance path 22 so that it can contact not only the IC chip of the IC card but the read head of the card reading unit 25. The roll paper drive motor 26 may be instructed to feed it upward.

  Further, the control unit 43 performs an operation (reciprocation operation of the cleaning sheet) of repeating the winding and feeding of the cleaning sheet in a state where the cleaning sheet is in contact with the IC chip portion and the read head of the card reading portion 25 The cleaning sheet may be taken up and stored after the motor 26 has performed a predetermined number of times. Here, the predetermined number of reciprocation operations of the cleaning sheet may be a number determined according to the error code, for example, two times in the case of a slip code, and three times in the case of a lead-out code. Thereby, the contamination which is difficult to wipe off can be removed by increasing the number of wiping operations for contamination that is difficult to wipe off, such as oil and fat. Further, the predetermined number of reciprocation operations of the cleaning sheet may be determined in accordance with the predetermined number used in the determination by the determination unit 41. For example, the predetermined number of reciprocation operations may be increased as the predetermined number is increased, that is, as the reading becomes difficult. Thus, the cleaning can be performed carefully enough to be difficult to read.

  Further, the control unit 43 controls the roll paper drive motor 26 to feed the cleaning sheet 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 nighttime). May be Thus, not only the IC chip portion of the IC card or the read head of the card reading portion 25 but also the cleaning of the card conveyance path 22 can be performed.

  Moreover, although the cleaning sheet mentioned above is a sheet comprised with one raw material, it is not restricted to this.

  For example, as shown in FIG. 6, the cleaning sheet is composed of a front portion and a rear portion including the leading end of the cleaning sheet along the cleaning sheet propelling and winding directions, and different materials (first material and 2 materials). The second material of the rear portion may be a material having a higher cleaning efficiency than the first material of the front portion. The material having a high cleaning efficiency is, for example, a material having a high contamination removal rate. In the case of a material with high cleaning efficiency, there is also a possibility that damage such as scratches will be caused to the IC chip portion of the IC card, 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 retracts to the card retracting unit 24, the control unit 43 feeds the cleaning sheet so that the front portion of the cleaning sheet can contact the IC chip of the IC card. The roll paper drive motor 26 is controlled to control the roll paper drive motor 26, and the roll paper drive motor feeds the cleaning sheet so that the rear end portion of the cleaning sheet can contact the IC chip portion of the IC card according to the reading result of the IC card information thereafter. Control 26

  Here, feeding the cleaning sheet so that the latter part of the cleaning sheet can contact the IC chip part of the IC card according to the reading result is, for example, cleaning at the former part of the cleaning sheet after one retry instruction. After cleaning, for example, when it is not possible to read the information on the IC card even if there are three retry instructions, it means that the cleaning sheet is fed out so that the rear part of the cleaning sheet abuts on the IC chip of the IC card. .

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

  Here, an example of the process until cleaning of the IC card (IC chip portion) is described with reference to FIGS. 8A to 8D. FIG. 8A is a diagram showing a state in which the IC card is retracted to the card retraction unit 24 by the retraction control unit 42. As shown in FIG. 8A, the card retractor 24 retracts 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 conveyance path 21. Thus, when the cleaning sheet is fed onto the card conveyance path 22, the cleaning sheet can be in contact with the surface of the IC chip portion and wipe the surface of the IC chip portion.

  FIG. 8B is a view showing a state in which the cleaning sheet has been fed onto the card conveyance path 22. FIG. 8B shows the case where the cleaning liquid is wiped on the cleaning sheet when the cleaning sheet is fed out, but as described above, it is possible to wipe the cleaning liquid depending on the content of the error code. Good. In addition, after the cleaning sheet is fed onto the card conveyance path 22, the cleaning sheet is not merely wound up to clean the IC chip portion or the read head of the card reading portion 25, but as described above, the cleaning sheet A reciprocating operation may be performed to clean the IC chip unit and the read head of the card reading unit 25.

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

  FIG. 8D shows a state in which the IC card of the card evacuation unit 24 is returned to the card conveyance path 22, and the IC card is being read again. If the reading is successful by reading again after cleaning, it is possible to continue the transaction without having the customer wipe the IC card or reinsert the IC card.

  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 central processing unit (CPU) 91, a hard disk drive (HDD) 92, a read only memory (ROM) 93, a random access memory (RAM) 94, a card read unit 21, and a bus 95. . The CPU 91, the HDD 92, the ROM 93, the RAM 94, and the card read unit 21 are connected to one another via, for example, a bus 95.

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

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

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

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

  Next, an example of the automatic cleaning process of the ATM according to the embodiment will be described with reference to FIG. As shown in FIG. 10, when the IC card is inserted into the card insertion slot 14, the reading process of the IC card is started (step S1001). It is checked whether a read error has occurred (step S1002), and if it does not occur (No in step S1002), the process ends. If it occurs (Yes in step S1002), the operation unit 40 can not read the information of the IC card due to a predetermined error, and the number of times the reading of the information of the IC card is tried again, that is, the number of retry instructions. It counts (step S1003). The determination unit 41 determines whether the counted number is equal to or more than a predetermined number (step S1004).

  When the counted number of times is equal to or more than the predetermined number (Yes in step S1004), the save control unit 42 causes the card save unit 24 to save the IC card (step S1005). When the counted number is smaller than the predetermined number (No in step S1004), the reading of the information of the IC card is tried again.

  After the IC card is retracted to the card retraction unit 24, the control unit 43 feeds the cleaning sheet stored in the cleaning sheet storage unit 27 onto the card conveyance path 22 so that it can contact the IC chip of the IC card. After driving and controlling the roll paper drive motor 26, and after the cleaning sheet is in contact with the IC chip portion, that is, after the cleaning sheet is brought into contact with the soiled portion of the IC chip portion, the cleaning sheet is wound to wipe the soiled portion. The roll paper drive motor 26 is instructed to take it (step S1006). Based on this instruction, the cleaning sheet is taken 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 try reading information of the IC card after cleaning again.

  According to the above-described ATM, it is possible to read an IC card and start a transaction early, without the trouble of the customer. Moreover, according to the above-mentioned ATM, it is possible to reduce transaction loss and cleaning response by the maintenance worker.

  In the embodiment described above, the main processing of the ATM is described as being executed by software processing by the CPU, but all or part of this processing may be realized by hardware.

  In addition, the above-described embodiment is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the embodiment.
