Description

  The present invention relates to a recording medium reading device that accepts insertion of a recording medium on which information is recorded and reads information from the inserted recording medium, and an automatic transaction apparatus using the recording medium reading device. Regarding the prevention of theft of recorded information.

  With the expansion of the use of automatic transaction devices such as automatic teller machines (ATMs) and cash payment machines (CDs), fraudulent transactions using counterfeit cards have become a major social problem.

  In particular, a device that improperly reads card information (hereinafter referred to as a skimming device) that resembles the shape of the card insertion slot of an automatic transaction apparatus is attached to the card insertion slot, and the card is inserted into the card insertion slot when a user makes a transaction. There are a number of reports on how to create counterfeit cards by stealing card information without the user's knowledge.

  As a means for preventing the card information from being stolen by the skimming device, a skimming device is provided by using a structure in which a shutter is provided in front of the card insertion slot and the skimming device interferes with the skimming device. A method for preventing the device from being attached has been proposed (see Patent Document 1).

JP 2008-191916 A

  A typical example of the skimming device is to incorporate a magnetic head in the skimming device and read information recorded on the magnetic stripe of the magnetic card. In addition, there is an example in which a line scanner is incorporated in a skimming apparatus to read a pattern or character information printed or stamped on a card.

  Such a skimming device is attached in the vicinity of the ATM card insertion slot in a state that is difficult for the user to recognize, and waits for the card to be inserted by the user. When a card is inserted into an ATM, the skimming device illegally steals information by using a structure in which the card passes while sliding on a magnetic head or a line scanner inside the skimming device.

  In recent years, skimming devices have been reduced in size, and some skimming devices can be attached if there is a place of a few tens of millimeters in the card conveying direction. In addition, a case where a skimming device is installed in the gap between the ATM main body and the card portion, a case where a forming wall of the ATM main body is hollowed out, and a skimming device is embedded therein, etc. You can also see how to install.

  In the recording medium receiving device described in Patent Document 1, when the skimming device is attached to the inside of the device such as the inner side of the shutter or the back side of the insertion hole, the recording medium receiving device may not be able to detect the skimming device. . Further, since the shutter is opened before the user tries to insert a card, a mechanism for accurately detecting the presence of the user is also required.

  An object of the present invention is to solve the above-mentioned problems related to prevention of attachment of such a skimming device and to enhance the effectiveness of prevention of information theft.

In order to achieve the above object, the present invention provides a recording medium reader,
An insertion slot into which a recording medium is inserted; an information reading unit that reads information from the recording medium; and a recording medium clamping unit that clamps the recording medium inserted into the insertion slot. The recording medium sandwiching section is disposed at the insertion port, and when the recording medium is transported to the information reading section, at least a part of the recording medium sandwiching section together with the recording medium is A structure for entering the inside of the apparatus from the outside of the insertion port is provided.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to an automatic transaction apparatus such as an ATM installed in a financial institution or the like.

  FIG. 1 is a schematic perspective view schematically showing an external appearance of an automatic transaction apparatus 1 according to the present embodiment. FIG. 2 is a block diagram schematically showing the internal configuration of the automatic transaction apparatus 1. 3 and 4 are explanatory views schematically showing a configuration around the card insertion slot, which is a main configuration of the automatic transaction apparatus 1 of the present embodiment, and FIG. 3 is a perspective view around the card insertion slot 30, and FIG. 4 (A) is a front view, and FIG. 4 (B) is a side view.

  The automatic transaction apparatus 1 is an automatic transaction apparatus that conducts transactions such as cash deposits and withdrawals by a user's operation, displays an operation guide, and simultaneously detects a user input and cash deposits and withdrawals. A banknote section 40 to be performed; a card insertion slot 30 that accepts insertion of a card C that is a recording medium on which information such as a user's account number is recorded; and a card section 100 that handles a card C inserted from the card insertion slot 30 The controller 10 controls these parts.

  The card unit 100 includes a magnetic head 106 that is an information reading unit that reads information on a magnetic stripe attached to the back surface of the card C, and a card holding and conveying unit 105 (hereinafter, presenter 105) that conveys the inserted card to the magnetic head 106. )), A conveyance roller 103 that conveys the card C so that the magnetic head 106 reads the magnetic stripe, a presenter 105, a conveyance motor 104 that drives the conveyance roller 103, a sensor 102 that detects the position of the presenter 105, The card control unit 101 is configured to control the transport motor 104, the sensor 102, and the magnetic head 106 and communicate with the upper control unit 10.

  The presenter 105 is composed of a pair of an upper presenter 105a positioned above the transport path in which cards are transported and a lower presenter 105b positioned below the transport path. The upper presenter 105a and the lower presenter 105b are inserted cards. In order to sandwich C from above and below, they are arranged in a positional relationship facing each other across the card transport path.

  The lower presenter 105b is connected to a rotating shaft, and is moved along the guide 107 by a transport motor 104 connected to the rotating shaft. The upper presenter 105a is also connected to the motor 104, and rotates in the transport direction when the card C is transported.

  Further, the lower presenter 105b is in a state of being pushed out from the card insertion slot 30 to the outside of the apparatus, and a safety display D1 is displayed on the surface of the protruding portion so as to be visible to the user. It moves to the inside of the device.

  The insertion of the card C is detected by the sensor 102. The sensor 102 monitors the rotating shaft connected to the lower presenter 105b as shown in FIG. 4B, and detects the insertion of the card C from the operation of the presenter 105b. Other than this, it is attached to the rotating shaft of the lower presenter 105b and detects card insertion, or is present in the vicinity of the presenter 105 and optically detects insertion of the card C from the movement of the presenter, and the lower presenter 105b is connected to the card C. It may be one that senses contact.

  Next, the operation of the card unit 100 when the card C is inserted will be described with reference to the explanatory diagrams of FIGS. In each figure, (A) is a front view and (B) is a side view. 5 to 7 show a normal operation in which no skimming device is attached, and the card to be handled has a magnetic stripe on the back surface.

  In a state before the card C is inserted, the lower presenter 105b is at a position where the safety display D1 is displayed to the user (hereinafter, this position is referred to as “accepting position”). When the card C is inserted from the card insertion slot 30, the presenter 105 pinches the card C and starts conveying the card C (FIG. 5).

  When the conveyance of the card C is started, the sensor 102 detects that the card C is inserted into the presenter 105. The card control unit 101 that detects the output of the sensor 102 controls the transport motor 104, whereby the upper presenter 105a rotates, and the lower presenter 105b enters the inside of the apparatus from the card insertion slot 30 along the guide 107. The card C is held between the upper presenter 105a and the lower presenter 105b, and is taken into the apparatus by the frictional force of the presenter 105. At this time, the safety display D1 displayed on the surface of the lower presenter 105b enters the inside of the apparatus together with the card C from the card insertion slot 30. By visually recognizing this state, the user can determine that the skimming device is not attached to the outside of the device near the insertion slot.

  Further, in order to improve the visibility of the situation where the lower presenter 105b enters the inside of the apparatus, a safety display D2 different from the safety display D1 is displayed on the surface of the guide 107 located at the back of the lower presenter 105b (FIG. 6). .

  These safety indications may be indicated by graphics, characters, or the like, or may be expressed by changing the color of the visible surface. Moreover, the structure which expresses a safety display by light emission, such as LED and a lamp | ramp, may be sufficient. Note that the same effect can be obtained even when the lower presenter is not in a state of protruding outward.

  After the lower presenter 105b has completely entered the apparatus, the safety display D2 is displayed for the user. Further, after the card C is conveyed into the apparatus and released from the pinching of the presenter 105, the card C is conveyed by the conveying roller 103, and reading of the magnetic stripe is completed by the magnetic head (FIG. 7).

  As described above, the configuration and operation of the presenter 105 shown in FIGS. 5 to 7 can prevent the skimming device from being attached on the path along which the presenter 105 moves. Further, while the presenter 105 holds and conveys the card C, the surface of the lower presenter 105b on which the safety display D1 is displayed is in contact with the magnetic stripe of the card C, and the card is sent into the apparatus by frictional force. Yes. Therefore, even if a small skimming device is attached to the surface of the presenter, the card C does not slide on the skimming device, so that information on the magnetic stripe can be prevented from being stolen.

  Next, operation | movement of the automatic transaction apparatus 1 in case a user uses the automatic transaction apparatus 1 and performs a transaction is demonstrated using FIGS. 8-10. FIG. 8 is an example of a transaction processing flow in the automatic transaction apparatus 1. When the transaction is started, the card reading process (step S1) starts in response to the customer's card insertion. When the card reading is completed normally, the user is allowed to select a transaction (step S2). When the transaction is completed normally, a card return process (step S3) is performed. The overall processing flow is as follows. FIG. 9 is an example of an operation flow showing details of the card reading process S1 in the flow of FIG. FIG. 10 is an example of an operation flow showing details of the card return process S3 in the flow of FIG.

  Usually, in a state before the user starts a transaction, the automatic transaction apparatus 1 displays a screen such as an advertisement on the display input unit 20. At this time, the lower presenter 105b is at the reception position, and the sensor 102 monitors the rotating shaft to which the lower presenter 105b is connected (step S11).

  When the user inserts the card C into the card insertion slot 30, the card C is sandwiched between the presenters 105, the lower presenter 105b is moved by the frictional force between the card C and the presenter 105, and the sensor 102 is moved to the card C by the movement of the lower presenter 105b. Is detected (step S12).

  When the sensor 102 detects the insertion of the card C, the conveyance of the card C is started (step S13). At this time, the conveyance motor 104 is driven, and the lower presenter 105b moves into the apparatus together with the card (step S14). The card C is conveyed to the magnetic head 106 by the presenter 105.

  When the card C normally reaches the magnetic head 106 (step S15), the magnetic stripe surface of the card C slides on the magnetic head 106 by driving the presenter 105 and the conveyance roller 103, and the magnetic head 106 records on the magnetic stripe. The read information is read (step S16).

  If there is an abnormality in the card conveyance in step S13, the sensor 102 monitoring the rotation axis to which the presenter 105 is connected detects an abnormality in the conveyance status of the presenter 105. In this case, the card unit 100 performs error processing (step S17).

  When the card reading process ends normally, the automatic transaction apparatus 1 displays a transaction selection screen on the display input unit 20 and executes the transaction content selected by the user (step S2). When the transaction process is completed normally, the process proceeds to the card return process step 3.

  In the card return process, the card C is first transported in the direction of the insertion slot 30 by the transport roller 103 (step S31). When one end of the card C comes into contact with the lower presenter 105b, the lower presenter 105b starts moving in the direction of the insertion slot 30 due to the frictional force between the card C and the lower presenter 105b. When the card C is further conveyed and one end of the card C comes into contact with the upper presenter 105a, the card C is sandwiched between the upper presenter 105a and the lower presenter 105b. Thereafter, the presenter 105 transports the card C to the insertion slot 30 where the user can remove the card C by the transport motor 104 (step S32). At this time, the lower presenter 105 b moves from the inside of the apparatus to the insertion slot 30 and emerges from the insertion slot 30 together with the card C. When the user pulls out the card C, the lower presenter 105b returns to the receiving position due to the frictional force between the card C and the presenter 105, and the safety display D1 is displayed again for the user (step S33). If there is an abnormality in the card return in step S32, the sensor 102 monitoring the rotating shaft to which the presenter 105 is connected detects an abnormality in the conveyance status of the presenter 105, and the card unit 100 performs error processing. This is performed (step S34). When the return of the card is normally completed, a series of transaction processing is completed, and the process returns to step S1.

  Here, the case where a skimming apparatus is attached with respect to the automatic transaction apparatus which assumed the transaction by the card | curd provided with the magnetic stripe on the back surface is demonstrated using FIGS. In order for the skimming device S to steal information on the card C, the card C needs to slide on the skimming device S, so the skimming device S is attached so as to be in contact with the insertion path of the card C.

  FIGS. 11 and 12 show an example of a situation in which the skimming device S is attached to the front region of the insertion port 30, that is, the front panel that is outside the device. FIG. 13 and FIG. 14 are examples of situations where the skimming device S is directly attached to the insertion slot 30. FIG. 15 and FIG. 16 are examples of the situation where the skimming device S is attached to the back side of the front panel 2, that is, inside the device.

  When the skimming device S is attached outside the device, in the conventional automatic transaction device shown in FIG. 11, when the skimming device S that visually mimics the front panel of the automatic transaction device is attached, the user can It is difficult to recognize the presence of S. On the other hand, in the automatic transaction apparatus 1 of the present embodiment shown in FIG. 12, even when the skimming apparatus S that visually imitates the lower presenter 105b is attached, the user can display the safety display D1 in the process of inserting the card C. Cannot be seen from the card insertion slot 30 (FIG. 6). Therefore, safety can be easily determined.

  When the skimming device S is directly attached to the insertion slot 30, the skimming device S that visually mimics the front panel of the automatic transaction apparatus 1 and the insertion slot 30 is attached in the conventional automatic transaction apparatus shown in FIG. It is difficult for the user to recognize the presence of the skimming device S. On the other hand, in the automatic transaction apparatus 1 of the present embodiment shown in FIG. 14, the lower presenter 105b forms a part of the insertion slot 30, and the lower presenter 105b is configured to enter the inside of the apparatus. When the device S is attached, the lower presenter 105b interferes with the skimming device S. Therefore, since the lower presenter 105b cannot carry the card C, it is possible to prevent the card information from being stolen.

  When the skimming device S is attached inside the device, it is difficult for the conventional automatic transaction device shown in FIG. 15 to detect the skimming device S, and it is difficult for the user to recognize the presence of the skimming device S. . On the other hand, in the automatic transaction apparatus 1 according to the present embodiment shown in FIG. 16, the skimming apparatus S is separated from the transport path by the structure of the lower presenter 105b, so that the card C does not slide on the skimming apparatus S in the insertion process. Therefore, the skimming device cannot scan the information recording surface of the card, and can prevent the card information from being stolen.

  As described above, in the automatic transaction apparatus 1 according to the present embodiment, even if the skimming device S is attached to any part outside the apparatus, the insertion port, or the inside of the apparatus, the recorded information of the card C is not noticed by the user. Can be prevented from being stolen.

  In the first embodiment, a card having a magnetic stripe on the back surface is targeted. In the second embodiment, a configuration for a card having a magnetic stripe on the front surface will be described.

  In the present embodiment, as shown in FIG. 17, the upper presenter 105a is an arc-shaped plate that goes in and out of the apparatus together with the card, and the lower presenter 105b has a roller shape. Since the magnetic stripe is on the surface of the card C, the magnetic head 106 is on the upper presenter 105a side. Further, the present embodiment also includes a transport motor 104 and a sensor 102 as in FIG.

  As in the first embodiment, this embodiment can prevent the skimming device from being attached and prevent the card information from being stolen.

  In the third embodiment, as shown in FIG. 18, both the upper presenter 105a and the lower presenter 105b are configured as arc-shaped plates that move inside and outside the apparatus as the card C moves. In the case of such a configuration, not only a card having a magnetic stripe only on the front or back surface of the card C but also a card having a magnetic stripe on both sides thereof can be handled.

  Further, by adopting such a configuration, it is possible to simultaneously prevent exploitation of information recorded on the front surface or the back surface.

  In the first to third embodiments, the presenter 105 is described as moving. However, as the fourth embodiment, a structure in which the presenter 105 is a belt as shown in FIG. 19 will be described.

  In this case, the user moves the safety display D1 displayed on the belt surface from the card insertion slot 30 to the inside of the apparatus together with the card C by the rotation of the belt, and displays the safety display displayed on the surface of the newly appearing belt. By visually recognizing the display D2 (FIG. 20), it is possible to determine that the skimming device is not attached to the insertion port or the outside of the device.

  In addition, since the presenter 105 is configured by a belt, it is possible to convey more stably than the arc-shaped plate used in the first to third embodiments. Furthermore, the recording medium clamping unit can be configured at a lower cost by using a belt.

  In the fifth embodiment, as shown in FIG. 21, a description will be given of a configuration for displaying the state around the insertion slot, the operation of the presenter 105, and the like on the display input unit 20 when the card C is inserted.

  With this configuration, the user can insert the card C while comparing the content displayed on the display input unit 20 with the periphery of the actual insertion slot at the time of insertion. Therefore, when the skimming device is attached, the user notices the presence of the skimming device, so that the card information can be prevented from being stolen.

  Although each embodiment has been described, an embodiment configured by combining any of the presenter shapes shown in the above embodiments is also conceivable.

  In addition, the material of the presenter 105 is preferably a material having a high frictional force, but it is not necessary to be present in the presenter 105 as a whole, and a structure using a material having a high frictional force in part may be used. Furthermore, materials having different frictional forces between the upper presenter 105a and the lower presenter 105b may be used.

  In each embodiment, the present invention has a configuration in which the conveyance motor 104 is connected to the presenter 105. However, a configuration in which the present motor 105 is manually operated without the conveyance motor 104 may be used.

  With the above-described configuration, the present invention can provide a recording medium reading device that prevents the attachment of the skimming device and enhances the effectiveness of preventing theft of information.
