  Next, the structure of the card insertion / discharge port unit 10 according to the first embodiment and the structure of the main part of the card processing apparatus 100 to which the unit 10 is attached will be described with reference to FIGS. Reference is also made to FIGS. 1 and 2 as appropriate. In FIG. 5, a perspective view seen from the back side of the card insertion / discharge port unit 10 is shown in (a), and a partially broken perspective view is shown in (b). The same applies to FIG. 7 described later.

  As shown in FIG. 3, a card insertion / exit portion 1 a is provided on the front surface 1 f of the main body 1 of the card processing apparatus 100. The card inlet / outlet portion 1a protrudes forward (T direction in FIG. 3), and an inlet / outlet 1b is formed at the center.

  The small magnetic head 8b protrudes into the inlet / outlet 1b from below. By detecting the magnetic stripe of the magnetic card 20 inserted into the entrance / exit 1b, the small magnetic head 8b detects that a card in which magnetic information is recorded is inserted. Although the small magnetic head 8b may be affected by the disturbing magnetic field of the loop antenna 12, it is sufficient that the magnetic information can be detected at a predetermined level even if the magnetic information of the magnetic card 20 cannot be accurately read. There is no problem in detection performance.

  The entrance / exit 1b is opened or closed by moving the shutter 9a up and down by the driving force of the shutter drive unit 9 (FIG. 1). FIG. 2 shows a state in which the shutter 9a is lowered and the entrance / exit 1b is opened. A state in which the shutter 9a is raised and the entrance / exit 1b is closed is shown in FIG.

  As shown in FIG. 3, an opening 10 b for inserting and discharging the magnetic card 20 is formed at the center of the card insertion / discharge port unit 10. Through holes 10 c are formed on both sides of the card insertion / discharge port unit 10. The depth direction of the opening 10b and the through hole 10c is parallel to the card insertion direction S.

  As shown in FIG. 5A, a recess 10 a is formed on the back side of the card insertion / discharge port unit 10. The recess 10a communicates with the opening 10b. The size of the concave portion 10a is larger than the size of the convex portion 1e at the tip of the card insertion / exit portion 1a shown in FIG.

  As shown in FIG. 5, the card insertion / discharge port unit 10 is provided with a loop antenna 12. The loop antenna 12 is embedded in the card insertion / discharge port unit 10 with resins 14a and 14b so as to surround the recess 10a with the loop portion 12a.

  Specifically, the resin 14 a is a synthetic resin having thermoplasticity and constitutes a frame of the card insertion / discharge port unit 10. The resin 14b is a synthetic resin such as epoxy that cures in a short time. After the loop antenna 12 is mounted on the mounting portion 10s (FIG. 5B) formed of the resin 14a, the uncured resin 14b is applied so as to cover the loop antenna 12. And the loop antenna 12 is embed | buried in the card insertion discharge port unit 10 by hardening the resin 14b.

  The loop antenna 12 is composed of an air-core coil around which a copper wire is wound as shown in FIG. The outer dimensions of the loop antenna 12 viewed from the card insertion direction S are such that the horizontal width W1 is 56 mm to 110 mm, the vertical width H1 is 2 mm to 100 mm, and the depth D1 is 1 mm to 40 mm. The dimensions of the loop antenna 12 in the loop portion 12a are such that the horizontal width W2 is 55 mm to 109 mm, the vertical width H2 is 1 mm to 99 mm, and the depth D2 is 1 mm to 40 mm. The dimensions of the loop antenna 12 are set from the above range in consideration of the dimensions of each part of the magnetic card 20, the card processing device 100, and the ATM.

  As shown in FIG. 3, a board storage portion 10 d is provided on the upper portion of the card insertion / discharge port unit 10 so as to protrude in the card insertion direction S. As shown in FIG. 5A, the substrate 15 is fixed in the substrate storage portion 10d. On the substrate 15, the lead 12 b of the loop antenna 12, the circuit of the magnetic field generation unit 11 in FIG. 1, and the magnetic field control unit 13 are mounted. The substrate 15 and the loop antenna 12 are connected by the shortest wiring path.

  Next, a method for attaching and detaching the card insertion / discharge port unit 10 to / from the main body 1 of the card processing apparatus 100 and an operation of the card processing apparatus 100 will be described with reference to FIGS.

  From the separated state shown in FIG. 3, the convex portion 1e of the card insertion / exit portion 1a and the concave portion 10a (FIG. 5 (a)) of the card insertion / exit port unit 10 are fitted. Then, each screw hole 1c of the card insertion / exit portion 1a communicates with each through hole 10c of the card insertion / discharge port unit 10. For this reason, the card insertion / exhaust port unit 10 is inserted into the card entry / exit port of the main body 1 as shown in FIG. It is attached to the part 1a and is in a fixed state.

  Further, as shown in FIG. 3, the connector 18a of the harness 18 exposed from the main body 1 is fitted to the connector 18b mounted on the board 15 of the card insertion / discharge port unit 10 as shown in FIG. Then, the main body 1 and the card insertion / discharge port unit 10 are electrically connected.

  In the mounted state of the card insertion / ejection port unit 10 shown in FIGS. 2 and 4, the unit 10 covers the card insertion / exit portion 1a, the microswitch 8a, and the small magnetic head 8b from the outside. The loop portion 12a of the loop antenna 12 surrounds the card entrance / exit portion 1a.

  Furthermore, the opening 10b of the card insertion / discharge port unit 10 communicates with the entrance / exit 1b of the card entrance / exit portion 1a. For this reason, by inserting the magnetic card 20 in the S direction from the opening 10b, the magnetic card 20 enters the main body 1 through the inlet / outlet 1b.

  At that time, when the insertion of the magnetic card 20 is detected by the microswitch 8 a and the small magnetic head 8 b, the control unit 2 shown in FIG. 1 transmits a magnetic field generation command to the magnetic field control unit 13. When receiving the magnetic field generation command, the magnetic field control unit 13 causes the magnetic field generation unit 11 to radiate a disturbing magnetic field from the loop antenna 12.

  As another example, when a user stands in front of an ATM, an activation command is transmitted from the ATM to the card processing device 100. Then, the control unit 2 that has received the activation command by the host interface 7 may transmit a magnetic field generation command to the magnetic field control unit 13 and cause the magnetic field generation unit 11 to emit a disturbing magnetic field. In this case, a disturbing magnetic field is radiated by the magnetic field generator 11 before or simultaneously with the insertion of the magnetic card 20 into the card insertion / discharge port unit 10.

  When the card position detection sensor 6 (FIG. 1) detects that the magnetic card 20 has been taken into the main body 1, the control unit 2 conveys the magnetic card 20 by the card conveyance unit 5 (FIG. 1), and Then, a magnetic field stop command is transmitted to the magnetic field control unit 13. When the magnetic field control unit 13 receives the magnetic field stop command, the magnetic field generation unit 11 stops the emission of the disturbing magnetic field from the loop antenna 12. As another example, the disturbing magnetic field may be radiated for a predetermined time and then stopped.

  Thereafter, the magnetic information of the magnetic card 20 is read by the magnetic reading unit 4 (FIG. 1) while the magnetic card 20 is conveyed by the card conveying unit 5. When the processing for the magnetic card 20 is completed, the magnetic card 20 is conveyed by the card conveying unit 5 to the card insertion / exit port unit 10 through the card insertion / exit unit 1a, and is discharged from the opening 10b in the T direction (FIG. 2). . When the card is ejected, the magnetic field controller 13 may cause the magnetic field generator 11 to radiate a disturbing magnetic field from the loop antenna 12.

  At the time of maintenance of the card processing apparatus 100, the card insertion / ejection port unit 10 is removed from the screw holes 1c and the through holes 10c by a screwdriver or the like from the mounted state of FIG. It is possible to leave 1a. Further, by disconnecting the connector 18a from the connector 18b, the main body 1 and the card insertion / discharge port unit 10 are electrically disconnected.

  According to the first embodiment, the card insertion / ejection port unit 10 including the opening 10 b and the magnetic field generation unit 11 can be attached to and detached from the card insertion / exit portion 1 a of the main body 1 of the card processing apparatus 100. For this reason, by mounting the card insertion / ejection port unit 10 in the card insertion / exit part 1a and generating a disturbing magnetic field by the magnetic field generation part 11, unauthorized reading (skimming) of magnetic information on the magnetic card 20 by an unauthorized device is performed. Can be prevented.

  Further, by removing the card insertion / ejection port unit 10 from the card insertion / exit part 1a, replacement of the unit 10, the magnetic field generation part 11, the card entry / exit part 1a, the card insertion detection sensor 8, the shutter drive part 9, etc., Maintenance work such as repair and cleaning can be performed easily. Therefore, maintainability of the card insertion / discharge port unit 10 and the card processing apparatus 100 can be improved.

  In addition, since the magnetic field control unit 13 is provided in the card insertion / discharge port unit 10, the maintainability of the magnetic field control unit 13 can be improved. Further, by arranging the loop antenna 12 of the magnetic field generation unit 11, the drive circuit, and the magnetic field control unit 13 in an approaching state and connecting them with the shortest wiring path, generation of unnecessary parasitic circuits due to a long wiring path can be reduced. Can do. In addition, even if a high voltage is generated between the magnetic field generation unit 11 and the magnetic field control unit 13, it is possible to suppress the risk of electric shock or the like.

  A loop antenna 12 surrounds the card entrance / exit portion 1a. For this reason, a disturbing magnetic field is generated with respect to the card entrance / exit part 1a, and unauthorized reading of the magnetic information of the magnetic card 20 by an unauthorized device can be prevented.

  Further, the loop antenna 12 is embedded in the card insertion / discharge port unit 10 with resins 14a and 14b. For this reason, even if a rod-like foreign object is inserted into the card insertion / exit port unit 10 through the opening 10b or the hole of the ATM, the loop antenna 12 may be damaged or deformed by the unauthorized means. It is possible to prevent displacement and removal. In particular, when the loop antenna 12 is formed of a coil as in the present embodiment, it is possible to effectively prevent the coil from being deformed or disconnected by an unauthorized means as described above.

  Then, it is possible to prevent a fraud in which the direction of the disturbing magnetic field radiated from the loop antenna 12 is changed or to stop the disturbing magnetic field, and to stably maintain the radiation function of the disturbing magnetic field from the loop antenna 12. .

  Further, by selecting the outer dimensions of the loop antenna 12 and the dimensions in the loop portion 12a as described above, the dimensions of the loop antenna 12 can be changed according to the outer dimensions of the card to be handled and the dimensions of each part of the card processing apparatus 100. Can be set.

  Next, the structure of the card insertion / discharge port unit 10 according to the second embodiment will be described with reference to FIGS. Where appropriate, reference is also made to FIG.

  In the second embodiment, in addition to the configuration of the first embodiment described above, as shown in FIG. 7, the card insertion / discharge port unit 10 includes a pair of magnetic field changing members 17a and 17b. The magnetic field changing members 17a and 17b are magnetic bodies made of ferrite, permalloy, silicon steel plate, iron, aluminum, or stainless steel, and are formed in a shape as shown in FIG.

  As shown in FIG. 7, the horizontal portion 17c of the magnetic field changing members 17a and 17b is inserted into the concave portion 10a of the card insertion / discharge port unit 10 and held by the claws 10g. Further, the lock claws 17 d of the magnetic field changing members 17 a and 17 b are fitted into the lock holes 10 h of the card insertion / discharge port unit 10. Thereby, the magnetic field changing members 17 a and 17 b are fixed in the card insertion / exhaust port unit 10.

  As shown in FIG. 4, the card insertion / ejection port unit 10 including the magnetic field changing members 17 a and 17 b is attached to the card entry / exit portion 1 a of the main body 1 of the card processing apparatus 100 and fixed with screws 16. To do. Then, as shown in FIG. 9, the horizontal part 17c of the magnetic field changing members 17a and 17b covers the card entrance / exit part 1a from the vertical direction. Between the loop antenna 12 and the main body 1, vertical portions 17f of the magnetic field changing members 17a and 17b are interposed.

  The small magnetic head 8b is fitted into the notch 17e (FIG. 7) of the magnetic field changing member 17b (not shown). Other parts (not shown) are fitted into the notches 17g of the magnetic field changing member 17a (not shown).

  The magnetic field changing members 17 a and 17 b change the characteristics (distribution) of the magnetic field radiated from the loop antenna 12. Specifically, the vertical portions 17f of the magnetic field changing members 17a and 17b absorb the magnetic field from the loop antenna 12 toward the main body 1 side. Further, the horizontal portion 17c of the magnetic field changing members 17a and 17b increases the magnetic field from the loop antenna 12 toward the side opposite to the main body 1.

  According to the second embodiment, characteristics such as the direction and magnitude of the disturbing magnetic field radiated from the loop antenna 12 can be changed by the magnetic field changing members 17a and 17b. In particular, directivity is imparted to the disturbing magnetic field radiated from the loop antenna 12 by the vertical portion 17f and the horizontal portion 17c of the magnetic field changing members 17a and 17b, so that the disturbing magnetic field does not easily reach the main body 1 of the card processing apparatus 100. can do. For this reason, it is possible to prevent the magnetic information reading performance of the magnetic card 20 by the magnetic head 4a provided in the main body 1 from being deteriorated by the disturbing magnetic field.

  Moreover, the characteristics of the disturbing magnetic field radiated from the loop antenna 12 can be arbitrarily changed by appropriately setting the material, size, shape, and arrangement of the magnetic field changing members 17a and 17b.

  Further, the magnetic field changing members 17 a and 17 b are fixed in the card insertion / discharge port unit 10. For this reason, the magnetic field changing members 17a and 17b are displaced or removed by an unauthorized means such as a rod-like foreign object being thrust through the opening 10b of the unit 10 or an illegally opened hole in the ATM housing. Can be prevented.

  Furthermore, by forming the magnetic field changing members 17a and 17b so as to increase the rigidity, the magnetic field changing members 17a and 17b are prevented from being damaged or deformed by unauthorized means, and the magnetic field changing function is stabilized. Can be held in.

  The present invention can employ various embodiments other than the above-described embodiments. For example, in the second embodiment, in order to avoid a collision with the small magnetic head 8b, the example in which the notch portion 17e is provided in the magnetic field changing member 17b is shown, but the present invention is not limited to this. In addition, the notch 17e may be omitted from the magnetic field changing member 17b, and the small magnetic head 8b may be covered from the outside with the magnetic field changing member 17b as shown in FIG. 10, for example.

  Thus, the magnetic field changing member 17b can prevent the small magnetic head 8b for card insertion detection from being damaged or deformed by unauthorized means. In addition, the magnetic field from the loop antenna 12 toward the small magnetic head 8b can be reduced to prevent the magnetic detection performance of the small magnetic head 8b from deteriorating. Note that the notch 17g (FIG. 8) of the magnetic field changing member 17a may also be omitted.

  Moreover, although the above embodiment showed the example which enclosed the circumference | surroundings of the opening 10b of the card insertion discharge port unit 10 and the card | curd entrance / exit part 1a of the main body 1 with the loop antenna 12, this invention is limited to this. It is not a thing.
