  The slide part 13 is formed with a card passage hole 13a as a card passage part through which the card 2 passes. The card passage hole 13 a is connected to the card insertion slot 3. The width of the card passage hole 13a in the left-right direction is substantially equal to the width of the card passage hole 12a in the left-right direction. The slide portion 13 is connected to a shutter drive mechanism that drives the shutter member 11, and is slidable in the left-right direction by the power of a drive source such as a solenoid that constitutes the shutter drive mechanism. That is, the drive source constituting the shutter drive mechanism drives the shutter member 11 and the slide portion 13 in conjunction with each other.

  Also, a part of the power transmission mechanism that transmits power from the drive source of the shutter drive mechanism to the shutter member 11 and a part of the power transmission mechanism that transmits power from the drive source of the shutter drive mechanism to the slide unit 13 are common. It has become. Therefore, when the operation of the shutter member 11 is not completed for some reason, the operation of the slide member 13 is not completed, and when the operation of the slide unit 13 is not completed for some reason, the operation of the shutter member 11 is performed. Not complete. That is, when the operation of the shutter member 11 is completed, the operation of the slide portion 13 is also completed.

  In the present embodiment, in the standby state before the card 2 is inserted into the card insertion portion 4, as shown in FIGS. 2A and 2B, the right end portion 13b of the card passage hole 13a is The left end portion 13 c of the card passage hole 5 a is disposed on the left side of the right end portion 5 c of the card passage passage 5. That is, in the standby state, the end portions 13b and 13c of the card passage hole 13a and the end portion 5b of the card passage path 5 are arranged in the left and right direction so that the card 2 cannot pass from the card insertion portion 4 toward the main body portion 6. 5c is off.

  Further, when the insertion detecting means detects that the card 2 is inserted into the card insertion portion 4, the slide portion 13 slides to the right as shown in FIG. Specifically, in the left-right direction, the right end portion 13b of the card passage hole 13a substantially coincides with the right end portion 5b of the card passage passage 5, and the left end portion 13c of the card passage hole 13a is the left end portion 5c of the card passage passage 5. The slide part 13 slides in the right direction so as to substantially match. That is, when the card 2 is inserted into the card insertion portion 4, the slide portion 13 slides in the right direction so that the card 2 can pass from the card insertion portion 4 toward the main body portion 6 in the left-right direction. The end portions 13b and 13c of the passage hole 13a and the end portions 5b and 5c of the card passage 5 substantially coincide with each other.

  Note that when the card 2 is inserted into the card insertion portion 4, the slide portion 13 has only to slide rightward so that the card 2 can pass from the card insertion portion 4 toward the main body portion 6. When 13 slides to the right, the right end portion 13b of the card passage hole 13a substantially coincides with the right end portion 5b of the card passage passage 5 and the left end portion 13c of the card passage hole 13a is in the card passage passage 5 in the left-right direction. It may be arranged on the left side of the left end portion 5c. Similarly, when the slide portion 13 slides to the right, the left end portion 13c of the card passage hole 13a substantially coincides with the left end portion 5c of the card passage passage 5 and the right end portion 13b of the card passage hole 13a in the left-right direction. May be arranged on the right side of the right end portion 5 b of the card passage 5.

  In this embodiment, the slide amount of the slide portion 13 is substantially equal to the width of one magnetic track formed on the magnetic stripe 2a. The distance L1 from the front end (back end) 2c of the card 2 in the front-rear direction to the card insertion slot 3 when the insertion detecting means detects that the card 2 is inserted into the card insertion portion 4 is the card 2 Is a distance L2 or more from the tip 2c of the magnetic stripe 2a to the tip (back end) 2d of the effective data region 2b of the magnetic stripe 2a (see FIG. 2B). In FIG. 2 and FIG. 5 described later, the slide amount of the slide portion 13 is shown larger than the actual amount for convenience of explanation.

  The front panel 10 is formed with a card passage hole 10a through which the card 2 passes. As shown in FIG. 2, in the left-right direction, the right end portion 10b of the card passage hole 10a substantially coincides with the right end portion 5b of the card passage passage 5, and the left end portion 10c of the card passage hole 10a is in a standby state. Is substantially coincident with the left end 13c of the card passage hole 13a. The right end portion 10b of the card passage hole 10a may be formed on the right side of the right end portion 5b of the card passage path 5, and the left end portion 10c of the card passage hole 10a is the card passage hole 13a in the standby state. You may form in the left side from the left end part 13c.

  As described above, in the standby state before the card 2 is inserted into the card insertion portion 4, the card passage hole 13 a in the left-right direction is prevented so that the card 2 cannot pass from the card insertion portion 4 toward the main body portion 6. The end portions 13b and 13c are shifted from the end portions 5b and 5c of the card passage 5. Therefore, as shown in FIGS. 2A and 2B, in this state, the card 2 inserted from the front side of the front panel 10 cannot be taken into the main body unit 6. When the card 2 is inserted, the slide portion 13 slides to the right, and the end portions 13b, 13c of the card passage hole 13a and the end portions 5b, 5c of the card passage passage 5 substantially coincide with each other in the left-right direction. . Therefore, the card 2 inserted from the front side of the front panel 10 can be taken into the main body 6 as shown in FIG.

(Card reading operation of the card reader)
FIG. 3 is a flowchart for explaining an example of the operation of taking the card 2 into the card reader 1 shown in FIG.

  When it is detected that the card 2 has been inserted into the card insertion unit 4 in the standby state before the card 2 is inserted into the card insertion unit 4 (when “Yes” in step S1), the shutter drive mechanism is Upon activation, the shutter member 11 opens the card passage 5 and the slide portion 13 slides (moves) in the right direction (step S2). Thereafter, it is determined whether or not the shutter member 11 has normally opened the card passage 5 (step S3). As described above, the operation of the shutter member 11 and the operation of the slide portion 13 are interlocked. When the operation of the shutter member 11 is completed, the operation of the slide portion 13 is also completed, so that the shutter member 11 is normal. It is also possible to determine whether or not the slide portion 13 has normally slid rightward by determining whether or not the card passage 5 has been opened.

  In step S3, if the shutter member 11 normally opens the card passage 5 (that is, if the slide portion 13 is also sliding rightward in the case of “Yes” in step S3), The roller driving mechanism is activated, and the driving roller and the driving roller 8 arranged in the card insertion portion 4 are rotated, and the card 2 is taken into the main body portion 6 (step S4). When the loading of the card 2 into the main body 6 is completed (“Yes” in step S5), the driving roller and the driving roller 8 arranged in the card insertion unit 4 are stopped (step S6). Further, the shutter member 11 closes the card passage 5 and the slide portion 13 slides to the left (step S7), and the operation of taking the card 2 into the card reader 1 is completed.

  On the other hand, in step S3, when the shutter member 11 does not normally open the card passage 5 (or when the slide part 13 does not normally slide rightward, “No” in step S3). The card reader 1 notifies the host device of a shutter error that the shutter member 11 is not normally opened (step S8), and the card 2 is taken into the main body 6 until this error is cleared. No (step S9). That is, the card reader 1 waits until this error is cleared.

(Main effects of this form)
As described above, in this embodiment, the slide portion 13 slidable in the left-right direction constitutes the front end portion of the card insertion portion 4. Further, in this embodiment, in the standby state before the card 2 is inserted into the card insertion portion 4, the card passage hole 13a is formed in the left-right direction so that the card 2 cannot pass from the card insertion portion 4 toward the main body portion 6. When the card 2 is inserted into the card insertion part 4, the slide part 13 slides to the right and the card is inserted. The end portions 13b and 13c of the card passage hole 13a and the end portions 5b and 5c of the card passage path 5 substantially coincide with each other in the left-right direction so that the card 2 can pass from the portion 4 toward the main body portion 6.

  Therefore, in this embodiment, when the skimming device 52 on which the skimming magnetic head 51 is mounted is attached to the front panel 10 of the host device, the card 2 is taken into the main body 6 using the slide portion 13. Can be avoided. That is, for example, as shown in FIG. 4A, the card passage hole 13a when the right end 52b of the passageway 52a of the card 2 formed in the skimming device 52 attached to the front surface of the front panel 10 is in a standby state. The right end portion 13b of the card passage hole 52a substantially coincides with the left end portion 13c of the card passage hole 13a in the standby state in the left-right direction. Even if it is detected that the card 2 is inserted from the front side of the front panel 10 and the card 2 is inserted into the card insertion portion 4 and the slide portion 13 tries to slide rightward, the card 2 is caught by the skimming device 52. The slide part 13 does not slide rightward. Therefore, in this case, the card 2 is not taken into the main body 6.

  For example, as shown in FIG. 4B, the right end 52b of the passage 52a of the skimming device 52 attached to the front surface of the front panel 10 substantially coincides with the right end 5b of the card passage 5 in the left-right direction. And the card 2 inserted from the front side of the front panel 10 is inserted in the slide portion 13 when the left end portion 52c of the passage passage 52a substantially coincides with the left end portion 5c of the card passage passage 5 in the left-right direction. The card 2 cannot be inserted into the card insertion portion 4 by abutting against the front surface of the card (that is, the front surface of the card insertion portion 4). Therefore, also in this case, the card 2 is not taken into the main body 6.

  Thus, in this embodiment, when the skimming device 52 is attached to the front panel 10 of the host device, the card 2 may be prevented from being taken into the main body portion 6 by using the slide portion 13. it can.

  Further, in this embodiment, when the skimming device 52 is attached to the front panel 10 of the host device, the position of the magnetic track recorded on the magnetic stripe 2 a is shifted from the skimming magnetic head 51 using the slide portion 13. Thus, reading of significant magnetic data by the skimming magnetic head 51 can be prevented. That is, for example, as shown in FIGS. 5A and 5B, the right end 52b of the passage 52a of the skimming device 52 attached to the front surface of the front panel 10 is in the left-right direction with the right end 5b of the card passage 5. And the left end portion 52c of the passage 52a substantially coincides with the left end portion 13c of the card passage hole 13a in the standby state in the left-right direction, the card from the front side of the front panel 10 When 2 is inserted and it is detected that the card 2 is inserted into the card insertion portion 4, the card 2 slides to the right together with the slide portion 13. For this reason, in this embodiment, it is possible to prevent the magnetic track 51 from reading significant magnetic data by shifting the position of the magnetic track from the skimming magnetic head 51.

  Particularly in this embodiment, the distance L1 from the front end 2c of the card 2 to the card insertion slot 3 in the front-rear direction when the insertion detecting means detects that the card 2 is inserted into the card insertion portion 4 is Since the distance from the tip 2c to the tip 2d of the effective data area 2b of the magnetic stripe 2a is equal to or longer than L2, the skimming magnetic head 51 causes the effective data area 2b of the magnetic stripe 2a as shown in FIG. The card 2 in the middle of reading the magnetic data slides to the right together with the slide part 13 as shown in FIG. That is, in this embodiment, the card 2 is slid rightward while the magnetic data in the effective data area 2 b is being read by the skimming magnetic head 51, and the position of the magnetic track is shifted from the skimming magnetic head 51.

In addition, the position of the magnetic track recorded on the magnetic stripe 2 a can be shifted from the skimming magnetic head 51, thereby preventing reading of significant magnetic data by the skimming magnetic head 51. Therefore, in this embodiment, it is possible to prevent unauthorized acquisition of magnetic data by the skimming magnetic head 51. As a result, when the skimming countermeasure is applied to the host apparatus that has not been skimming countermeasures, It is possible to take skimming countermeasures for the host device without significantly modifying the housing.

  In this embodiment, the drive source constituting the shutter drive mechanism drives the shutter member 11 and the slide portion 13 in conjunction with each other. Therefore, the configuration of the card reader 1 can be simplified as compared with the case where the drive source of the shutter member 11 and the drive source of the slide portion 13 are provided separately. Further, since the slide portion 13 slides in conjunction with the shutter member 11, it is not necessary to add new control such as sliding the slide portion 13 in addition to the conventional opening / closing control of the shutter member 11. In addition, when an error occurs that the slide portion 13 does not slide normally, a conventional opening / closing error (shutter error) of the shutter member 11 may be used, so that it is not necessary to add a new error code. Therefore, in this embodiment, it is not necessary to change the internal firmware of the card reader 1, and as a result, it is not necessary to change the system software of the host device.

  In this embodiment, the slide amount of the slide portion 13 is substantially equal to the width of one magnetic track formed on the magnetic stripe 2a. Therefore, while minimizing the slide amount of the slide portion 13, the slide portion 13 is used to prevent the card 2 from being taken into the main body portion 6, and the magnetic track recorded on the magnetic stripe 2a. This position can be shifted from the skimming magnetic head 51 to prevent reading of significant magnetic data by the skimming magnetic head 51. Therefore, in this embodiment, it is possible to prevent unauthorized acquisition of magnetic data by the skimming magnetic head 51 while reducing the size of the card reader 1.

  In this embodiment, the insertion detection means for detecting that the card 2 has been inserted into the card insertion portion 4 detects the end of the card 2 in the left-right direction, whereby the card 2 is inserted into the card insertion portion 4. This is a width detection mechanism that detects the fact. For this reason, when a foreign object such as a deformed card having a narrow width in the left-right direction is inserted into the card insertion portion 4, the insertion of the card 2 is not detected, and the slide portion 13 does not slide rightward. Therefore, in this embodiment, it is possible to prevent foreign matter such as a deformed card having a narrow width in the left-right direction from being taken into the main body 6.
