[0004] Some existing card readers into which magnetic cards can be inserted have a flat front surface (the surface facing the user) of the card insertion slot, making it easy to attach a magnetic data stealing device (overlay gap). It is conceivable that a crime could be committed in which a magnetic data stealing device is attached to the front surface of the card insertion slot of such a card reader, and the magnetic data of a magnetic card inserted by another person is stolen.

[0005] The present invention has been made in view of the above circumstances, and has an object to prevent the theft of magnetic data by the attachment of a magnetic data theft member. [Means for solving the problem]

[0006] The card reader of the present invention comprises a card insertion section having an insertion port through which a card is inserted, a convex portion provided on the front surface of the card insertion section and protruding forward of the card insertion section, a destruction detection wiring provided inside the convex portion, and a detection portion that detects at least one of a break and a short circuit in the destruction detection wiring. Effect of the Invention

[0007] According to the present invention, it is possible to prevent the theft of magnetic data by the attachment of a magnetic data theft member. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] (Overall configuration of the card reader) Fig. 1 is a perspective view of a card reader 1 according to an embodiment of the present invention. Fig. 2 is an exploded perspective view of the card reader 1 shown in Fig. 1 with a front cover 11 removed. Fig. 3 is a diagram showing a card 2 which is an example of a target to be read by the card reader 1.

[0011] The card reader 1 of this embodiment is a device that reads data recorded on the card 2 and records data on the card 2. Specifically, the card reader 1 is a so-called dip-type card reader in which data is read and recorded by manually inserting the card 2 into the card reader 1 and removing the card 2 from the card reader 1. This card reader 1 is used by being mounted on a higher-level device such as a fuel dispenser or ATM at an unmanned or self-service gas station.

[0012] Card 2 is, for example, a rectangular vinyl chloride card with a thickness of about 0.7 to 0.8 mm. A magnetic stripe 2a on which magnetic data is recorded is formed on one side of card 2. Card 2 may also have a built-in IC chip, and the other side of card 2 may have an external connection terminal (not shown) for the IC chip. Card 2 may also be a PET (polyethylene terephthalate) card with a thickness of about 0.18 to 0.36 mm, a paper card of a predetermined thickness, or the like.

[0013] The card reader 1 comprises a card reader main body 3 and a case body 4 that covers the card reader main body 3. The card reader main body 3 comprises a main body frame 6 in which a card movement path 5 along which the card 2 moves is formed, a magnetic head 7 that performs at least one of reading magnetic data recorded on the card 2 and recording magnetic data to the card 2, and an IC contact block (not shown) having a plurality of IC contact springs for communicating data with an IC chip built into the card 2.

[0014] The case body 4 is composed of a front cover 11 in which an insertion slot 10 for the card 2 is formed, and a case body 12. The card reader 1 also includes a control board 13, which is a printed circuit board for control, as shown in Fig. 2. The control board 13 is an example of a detection unit that detects at least one of a break and a short circuit in the destruction detection wiring 33d described below.

[0015] In this embodiment, the manually operated card 2 moves in the X direction shown in Fig. 1 etc. In other words, the X direction is the movement direction of the card 2 moving along the card movement path 5. The card 2 is inserted in the X1 direction and removed in the X2 direction. The Z direction in Fig. 1 etc., which is perpendicular to the X direction, is the thickness direction of the card 2 moving along the card movement path 5, and the Y direction in Fig. 1 etc., which is perpendicular to the X and Z directions, is the width direction (short side width direction) of the card 2 moving along the card movement path 5.

[0016] In the following description, the X direction is the front-rear direction, the Y direction is the left-right direction, and the Z direction is the up-down direction. The X1 direction side, which is the side in the direction in which the card 2 is inserted into the card reader 1, is the "rear" side, and the X2 direction side, which is the side in the direction in which the card 2 is removed from the card reader 1, is the "front" side. The Y1 direction side, which is one side of the left-right direction, is the "right" side, the Y2 direction side, which is the other side of the left-right direction, is the "left" side, the Z1 direction side, which is one side of the up-down direction, is the "up" side, and the Z2 direction side, which is the other side of the up-down direction, is the "down" side. The surface of each part of the card reader 1 on the X2 direction side is the front side. The Y direction side of each part of the card reader 1 is the side.

[0017] The front cover 11 is disposed on the front side of the main frame 6 and covers the front side portion of the main frame 6. The front cover 11 also constitutes the front surface of the card reader 1. The front side of the front cover 11 is formed with a mounting surface 11a for mounting the card reader 1 to the upper device. The mounting surface 11a is a plane perpendicular to the front-rear direction. The front side of the front cover 11 is formed with an exposed portion 11b that is disposed in an opening formed in the front panel of the upper device. The exposed portion 11b is formed so as to protrude forward from the mounting surface 11a, and constitutes a part of the front panel of the upper device when the card reader 1 is attached to the upper device. The exposed portion 11b is an example of a card insertion portion having an insertion port 10 into which the card 2 is inserted.

[0018] Furthermore, the front cover 11 is formed with a finger insertion section 11c recessed from the front surface of the exposed section 11b toward the rear. The finger insertion section 11c is formed to a size that allows the user's finger to be inserted, and the user inserts the user's finger into this finger insertion section 11c when inserting a card 2 into the card reader 1 and when removing the card 2 from the card reader 1. The insertion slot 10 is formed on the front surface of the exposed section 11b, both left and right side surfaces of the finger insertion section 11c, and the rear surface.

[0019] A protrusion 14 is provided on the front surface of the exposed portion 11b in a portion adjacent to the insertion slot 10. As a result, only a portion of the portion surrounding the insertion slot 10 on the front surface of the exposed portion 11b is formed in a protruding shape by the protrusion 14, making it difficult to attach a magnetic data stealing member to the periphery of the insertion slot 10 on the front surface of the exposed portion 11b. In particular, it becomes difficult to attach a plate-shaped magnetic data stealing member having an opening communicating with the insertion slot 10 to the front surface of the exposed portion 11b. This makes it possible to suppress the stealing of magnetic data by the attachment of a magnetic data stealing member.

[0020] Furthermore, the protrusion 14 is provided at a position in the insertion slot 10 adjacent to the portion through which the magnetic stripe 2a of the card reader 1 inserted into the insertion slot 10 passes, i.e., in front of the magnetic head 7. This makes it more difficult to attach a magnetic data stealing device that requires a magnetic head or the like to be placed around the portion through which the magnetic stripe 2a passes in order to steal the magnetic data of the card 2.

[0021] When viewed from the Y direction, the protrusion 14 has a substantially triangular shape with a base parallel to the other parts of the front surface of the exposed portion 11b. Moreover, the upper surface 14a of the protrusion 14 is smoothly connected to the bottom surface of the insertion slot 10 (card movement path 5), so that the card 2 can be easily inserted into the insertion slot 10 by inserting the card 2 in the X1 direction so as to slide along the upper surface 14a.

[0022] Furthermore, rectangular portion 19n of flexible printed circuit board 19 is provided inside protrusion 14, and destruction detection wiring 33d is formed in rectangular portion 19n. Rectangular portion 19n and destruction detection wiring 33d will be described later with reference to FIG. 5. When protrusion 14 is destroyed, destruction detection wiring 33d inside protrusion 14 is disconnected or short-circuited, so that destruction of protrusion 14 can be detected. As a result, even if protrusion 14 is destroyed to attach a magnetic data stealing member, the stealing of magnetic data can be prevented by processing such as stopping the function.

[0023] The case body 12 is formed in a substantially rectangular box shape with an open front end. The front cover 11 and the case body 12 are fixed to each other with the rear end of the front cover 11 and the front end of the case body 12 abutting against each other. The case body 4 covers both the top and bottom, both the left and right, and both the front and back of the card reader body 3.

[0024] The control board 13 is a rigid board formed in a substantially rectangular flat plate shape. The control board 13 is fixed to the upper surface of a card housing portion of the main frame 6 in which the rear end portion of the inserted card 2 is housed. The magnetic head 7 is electrically connected to the control board 13 via a flexible printed circuit board 19. As shown in FIG. 2, a connector 22 to which the flexible printed circuit board 19 is connected is mounted on the control board 13.

[0025] The control board 13 has a data signal circuit layer in which a data signal circuit is formed for transmitting a signal (data signal) of magnetic data read from the magnetic stripe of the card 2 by the magnetic head 7 and a data signal to be recorded on the magnetic stripe of the card 2 by the magnetic head 7.

[0026] In this embodiment, if a criminal commits some kind of fraudulent act to illegally obtain data and a break or short circuit is detected in the destruction detection wirings 33a and 33b described below formed on the flexible printed circuit board 19, or a break or short circuit is detected in the destruction detection wiring 33d inside the protrusion 14, a process is performed to suppress the theft of magnetic data. This process is a predetermined process such as erasing the data stored in the control board 13, rendering the control board 13 unusable (disabled), or notifying an abnormality to a higher-level device.

[0027] (Structure of flexible printed circuit board) Fig. 4 is a development view of a first circuit layer 32 of the flexible printed circuit board 19. Fig. 5 is a development view of a second circuit layer 34 of the flexible printed circuit board 19. Fig. 6 is a cross-sectional view for explaining the multi-layer structure of the flexible printed circuit board 19.

[0028] As shown in Fig. 6, the flexible printed circuit board 19 includes a first circuit layer 32 (see Fig. 4), a second circuit layer 34 (see Fig. 5), and an insulating layer 35 that protects the first circuit layer 32 and the second circuit layer 34. As shown in Fig. 6, the insulating layer 35, the first circuit layer 32, the insulating layer 35, the second circuit layer 34, and the insulating layer 35 are laminated in this order from one surface to the other surface of the flexible printed circuit board 19. That is, the second circuit layer 34 overlaps the first circuit layer 32 with the insulating layer 35 interposed therebetween.

[0029] The multiple bending portions 20 are bendable portions formed on the flexible printed circuit board 19, and in the card reader 1 shown in Figures 1 and 2, the flexible printed circuit board 19 is stored in a bent state at the bending portions 20 (see Figure 2).

[0030] The flexible printed circuit board 19 has a Y-shape with three ends. A first end of the flexible printed circuit board 19 is connected to a connector 22 of the control board 13. A second end of the flexible printed circuit board 19 is connected to the magnetic head 7. A third end of the flexible printed circuit board 19 extends inside the protrusion 14. The flexible printed circuit board 19 is routed along the main body frame 6 in a state where it is bent into a predetermined shape at each of the bending portions 20.

[0031] The flexible printed circuit board 19 is composed of a connected portion 19a connected to the connector 22, a connected portion 19b connected to the magnetic head 7, a covering portion 19c covering the connected portion 19b, a connecting portion 19d connecting the connected portion 19b and the covering portion 19c, a connecting portion 19e connecting the connected portion 19a and the covering portion 19c, a connecting portion 19m connecting a rectangular portion 19n provided inside the convex portion 14 and the connecting portion 19e, and a grounding portion 19i connected to the connecting portion 19m.

[0032] The connected portion 19a is formed in a substantially rectangular shape. The connected portion 19b and the covering portion 19c are formed in a substantially square shape. The connecting portion 19d is formed in a linear shape. The connecting portion 19e is composed of a first linear connecting portion 19f and a second linear connecting portion 19g formed in a linear shape, and an elliptical connecting portion 19h having a substantially elliptical shape and disposed between the first linear connecting portion 19f and the second linear connecting portion 19g. One end of the first linear connecting portion 19f is connected to the connected portion 19a, and the other end of the first linear connecting portion 19f is connected to the elliptical connecting portion 19h. One end of the second linear connecting portion 19g is connected to the covering portion 19c, and the other end of the second linear connecting portion 19g is connected to the elliptical connecting portion 19h.

[0033] The first linear connection portion 19f and the second linear connection portion 19g are formed such that the first linear connection portion 19f and the second linear connection portion 19g are arranged on the same straight line when the flexible printed circuit board 19 is unfolded. The connection portion 19d is formed such that the second linear connection portion 19g and the connection portion 19d are perpendicular to each other when the flexible printed circuit board 19 is unfolded. Two through holes 19j and 19k are formed in the elliptical connection portion 19h.

[0034] The connected portion 19b is soldered and connected to the lower end of the magnetic head 7. The covering portion 19c covers the connected portion 19b from below. The connecting portion 19d is folded back so that the connected portion 19b is covered by the covering portion 19c. The connected portion 19b, the connecting portion 19d, and the covering portion 19c are covered by a resin sealing member (not shown). The connecting portion 19e is routed from the magnetic head 7 toward the rear side.

[0035] The first circuit layer 32 (see FIG. 4) is formed with a data signal circuit 31a for transmitting data signals (specifically, for transmitting at least one of a signal of data read from the card 2 and a signal of data recorded on the card 2) and destruction detection wiring 33a for detecting a break or short circuit in the circuit itself. The second circuit layer 34 (see FIG. 5) is formed with a data signal circuit 31b for transmitting data signals and destruction detection wiring 33b for detecting a break or short circuit in the circuit itself.

[0036] The data signal circuit 31a of the first circuit layer 32 is connected to the data signal circuit 31b of the second circuit layer 34 via a connection portion 31c that provides electrical continuity from the first circuit layer 32 to the second circuit layer 34. The destruction detection wiring 33a of the first circuit layer 32 is connected to the destruction detection wiring 33b of the second circuit layer 34 via a connection portion 33c that provides electrical continuity from the first circuit layer 32 to the second circuit layer 34.

[0037] In addition, the first circuit layer 32 is formed with destruction detection wiring 33f for detecting its own disconnection and short circuit. In the second circuit layer 34, destruction detection wiring 33d, 33h for detecting its own disconnection and short circuit are formed. One end of the destruction detection wiring 33f of the first circuit layer 32 is connected to the destruction detection wiring 33d of the second circuit layer 34 through a connection portion 33e that conducts from the first circuit layer 32 to the second circuit layer 34. The other end of the destruction detection wiring 33f of the first circuit layer 32 is connected to the destruction detection wiring 33h of the second circuit layer 34 through a connection portion 33g that conducts from the first circuit layer 32 to the second circuit layer 34. In addition, a ground circuit 38 connected to the ground portion 19i is formed in the first circuit layer 32.

[0038] 4 and 5, the outer shape of the first circuit layer 32 and the outer shape of the second circuit layer 34 are substantially the same as the outer shape of the flexible printed circuit board 19. In addition, the outer shape of the insulating layer 35 is also substantially the same as the outer shape of the flexible printed circuit board 19.

[0039] The data signal circuits 31a and 31b transmit magnetic data signals. The data signal circuits 31a and 31b are configured with a plurality of pattern wirings. In this embodiment, the magnetic head 7 is a three-channel type magnetic head, and the data signal circuits 31a and 31b are configured with six pattern wirings. One end of the data signal circuits 31a and 31b (the end on the data signal circuit 31a side) is connected to the magnetic head 7, and the other end of the data signal circuits 31a and 31b (the end on the data signal circuit 31b side) is connected to the control board 13.

[0040] A destruction detection signal, which is a rectangular wave digital signal, flows through the destruction detection wirings 33a and 33b. The destruction detection wirings 33a and 33b are configured by a single wiring formed on the flexible printed circuit board 19. In the example of Figs. 4 and 5, the destruction detection wiring 33a of the first circuit layer 32 is densely laid out in the first straight connection portion 19f. The destruction detection wiring 33b of the second circuit layer 34 is densely laid out in the covering portion 19c, the second straight connection portion 19g, and the elliptical connection portion 19h.

[0041] One end of the wiring forming the destruction detection wiring 33a, 33b is connected to a destruction detection circuit formed on the control board 13, and the other end of the wiring forming the destruction detection wiring 33a, 33b is grounded. In addition, one end of the wiring forming the destruction detection wiring 33a, 33b is connected to a battery mounted on the control board 13 via the destruction detection circuit of the control board 13. The destruction detection wiring 33a, 33b is routed from the connected part 19a through the first straight connection part 19f, the elliptical connection part 19h, the second straight connection part 19g, and the covering part 19c in this order, and then folded back at the covering part 19c and routed to the connected part 19a.

[0042] The destruction detection circuit formed on the control board 13 performs the above-mentioned process of suppressing the theft of magnetic data when it detects at least one of a break and a short circuit of the destruction detection wirings 33a, 33b based on a change in the potential of the destruction detection wirings 33a, 33b. This makes it possible to perform the above-mentioned process of suppressing the theft of magnetic data when processing of the connection portion 19e of the flexible printed circuit board 19 or the like is performed.

[0043] A destruction detection signal, which is a digital signal having a rectangular wave shape, flows through the destruction detection wirings 33d, 33f, and 33h. The destruction detection wirings 33d, 33f, and 33h are configured by a single wiring formed on the flexible printed circuit board 19. In the example of Figs. 4 and 5, the destruction detection wiring 33d is densely laid out in the rectangular portion 19n in the second circuit layer 34. The rectangular portion 19n has two bent portions 20 and is three-dimensionally provided in a bent state inside the protrusion 14 (see Fig. 2), so that the destruction detection wiring 33d is also three-dimensionally arranged inside the protrusion 14.

[0044] One end of the wiring forming the destruction detection wiring 33d, 33f, 33h is connected to a destruction detection circuit formed on the control board 13, and the other end of the wiring forming the destruction detection wiring 33d, 33f, 33h is grounded. In addition, one end of the wiring forming the destruction detection wiring 33d, 33f, 33h is connected to a battery mounted on the control board 13 via the destruction detection circuit of the control board 13. The destruction detection wiring 33d, 33f, 33h is routed from the connected part 19a through the first straight connection part 19f, the elliptical connection part 19h, the connection part 19m, and the rectangular part 19n in this order, and then folded back at the rectangular part 19n and routed to the connected part 19a.

[0045] The destruction detection circuit formed on the control board 13 performs the above-mentioned process to suppress the theft of magnetic data when it detects at least one of a break and a short circuit of the destruction detection wirings 33d, 33f, 33h based on a fluctuation in the potential of the destruction detection wirings 33d, 33f, 33h. As a result, for example, when the protrusion 14 is destroyed to attach a magnetic data theft member to the front surface of the exposed portion 11b, a break or short circuit occurs in the destruction detection wiring 33d inside the protrusion 14, and the theft of magnetic data can be suppressed.

[0046] (Main effects of this form) In the card reader 1 of this embodiment, a protrusion 14 that protrudes forward from the exposed portion 11b is provided on the front surface of the exposed portion 11b (card insertion portion) having the insertion port 10 into which the card 2 is inserted, making it difficult to attach a magnetic data stealing member to the front surface of the exposed portion 11b and preventing the stealing of magnetic data. Furthermore, in the card reader 1, a destruction detection wiring 33d is provided inside the protrusion 14, and at least one of a break and a short circuit of the destruction detection wiring 33d is detected, so that even if the protrusion 14 is destroyed to attach a magnetic data stealing member, the stealing of magnetic data can be prevented by processing such as stopping the function.

[0048] For example, although a configuration has been described in which the destruction detection wirings 33d, 33f, and 33h are arranged to pass through the first circuit layer 32 and the second circuit layer 34, the destruction detection wirings 33d, 33f, and 33h may also be arranged to pass through the first circuit layer 32 or the second circuit layer 34.

[0049] In addition, a configuration has been described in which the flexible printed circuit board 19 is provided with the destruction detection wirings 33a, 33b and the destruction detection wirings 33d, 33f, and 33h. However, the flexible printed circuit board 19 may be provided with the destruction detection wirings 33d, 33f, and 33h, but may not be provided with the destruction detection wirings 33a and 33b.

[0050] Furthermore, the wiring pattern of the destruction detection wires 33a, 33b, 33d, 33f, and 33h that are densely laid out on the flexible printed circuit board 19 is not limited to the wiring patterns shown in FIGS. 4 and 5, and can be designed arbitrarily.

[0051] Although the flexible printed circuit board 19 has been described as having a multi-layer structure, the flexible printed circuit board 19 may have a single-layer structure. Also, although the flexible printed circuit board 19 on which the data signal circuits 31a and 31b are provided has been described as having the destruction detection wirings 33d, 33f, and 33h, the destruction detection wirings 33d, 33f, and 33h may be provided on a flexible printed circuit board other than the flexible printed circuit board 19.

[0052] Furthermore, the position where the convex portion 14 is provided on the exposed portion 11b is not limited to the position shown in Figure 1 etc., but may be any position that prevents the attachment of a magnetic data stealing device of the type that is attached to the front surface of the exposed portion 11b to the front surface of the exposed portion 11b.
