Detailed ways

Embodiments of the present invention will be described below with reference to the drawings.

First, the configuration of the card reader 100 according to this embodiment will be described with reference to FIGS. 1 to 4 . As shown in FIG. 1 , the card reader 100 of this embodiment includes: a housing 1, conveying rollers 2a to 2c, transmissive optical sensors 3a and 3b, and a contact block 4 including a movable member 11 (refer to FIG. 2 ). The conveyance rollers 2a-2c are an example of the "transportation member" of this invention.

The casing 1 is provided with an insertion opening 1 a for inserting the IC card 200 . The transport rollers 2a to 2c are provided as a pair of upper and lower sides of the transport path P, respectively. The transport rollers 2 a to 2 c transport the IC card 200 in an insertion direction (arrow A direction) and an ejection direction (arrow B direction). The photosensors 3 a and 3 b respectively include a light-emitting element and a light-receiving element, and are used to detect the position of the IC card 200 on the transport path P. As shown in FIG.

As shown in FIG. 2 , the contact block 4 includes a movable member 11 , a bracket 12 , a tension coil spring 13 (see FIG. 3 ), a driver 14 , and an arm 15 . The movable member 11 is formed with a claw portion 11 a protruding downward from an end portion in the arrow A direction, and an engaging portion 11 b engaged with one end of a tension coil spring 13 (see FIG. 3 ). In addition, shafts 11c and 11d are attached to the movable member 11 .

Here, as shown in FIG. 1, the movable member 11 of this embodiment is provided with the contact terminal 11e and the neutralization brush 11f. This neutralizing brush 11 f is used to remove static electricity from an external terminal 200 a (see FIG. 8 ) provided on the surface of the IC card 200 . Moreover, as shown in FIG. 2, the static elimination brush 11f is attached to the claw part 11a provided in the end part in the arrow A direction. This static elimination brush 11f is an example of the "static elimination member" of this invention. A conductive spring member, a conductive roller, etc. may be used instead of 11 f of static elimination brushes as a "static elimination member" of this invention.

The bracket 12 is configured to hold the movable member 11 so as to be movable. This bracket 12 has a pair of side plates 12a and a connecting plate 12b connecting these side plates 12a. The pair of side plates 12a are each formed with a guide hole 12c for insertion of the shaft 11c and a guide hole 12d for insertion of the shaft 11d. The guide hole 12c has a horizontal portion extending in the direction of the arrows A, B, an inclined portion extending in the oblique direction, and a vertical portion extending in the direction orthogonal to the arrows A, B. As shown in FIG. The guide hole 12d has a horizontal portion extending in the directions of arrows A, B and an inclined portion extending in an oblique direction. In addition, a rotation shaft 12e is formed on one side plate 12a. An engaging portion 12f that engages with the other end of the tension coil spring 13 (see FIG. 3 ) is formed on the connecting plate 12b.

As shown in FIG. 3, the tension coil spring 13 applies force to the movable member 11 so that the shaft 11c of the movable member 11 is located at the upper end of the vertical portion of the guide hole 12c, and the shaft 11d is located at the upper end of the inclined portion of the guide hole 12d. upper end. The driver 14 is attached to the bracket 12 and has a plunger 14 a and an electromagnet 14 b that drives the plunger 14 a. Engaging pins 14c are provided on the plunger 14a. The arm 15 is formed in an L-shape, and has a notch 15a into which the engagement pin 14c is inserted and an insertion hole 15b into which the rotation shaft 12e is inserted.

In addition, as shown in FIG. 4 , the card reader 100 is provided with a motor 5 for driving the transport rollers 2 a to 2 c (see FIG. 1 ) and a control unit 6 for controlling the operation of the card reader 100 . In addition, the card reader 100 can communicate with a high-level device 150 such as an ATM (Automated Teller Machine: automatic cash transaction device) main body.

Next, the operation of the card reader 100 of this embodiment will be described with reference to the flowchart of FIG. 5 . Each step in this flowchart is executed by the control unit 6 (see FIG. 4 ).

First, the card reader 100 determines whether the IC card 200 (see FIG. 1 ) is inserted into the insertion port 1 a of the case 1 in step S1 . Card insertion can be detected by, for example, a sensor (not shown) provided near the insertion port 1a. When it is determined that the IC card 200 has not been inserted into the insertion port 1a, step S1 is repeated. That is, the card reader 100 stands by until the IC card 200 is inserted. Then, when it is judged that the IC card 200 is inserted into the insertion slot 1a, it will transfer to step S2.

In step S2, the conveyance rollers 2a-2c (refer FIG. 1) are rotated normally by driving the motor 5 (refer FIG. 4). Thereby, as shown in FIG. 6 , the IC card 200 is taken into the inside of the housing 1 and conveyed in the insertion direction (arrow A direction). At this time, as shown in FIG. 3 , in the contact block 4 , since the movable member 11 is pulled by the tension coil spring 13 , the movable member 11 is accommodated in the bracket 12 . Therefore, as shown in FIG. 6 , the IC card 200 is conveyed in the arrow A direction without contacting the neutralizing brush 11 f.

Next, in step S3 of FIG. 5 , it is determined whether or not the optical sensor 3 b (see FIG. 6 ) has detected the IC card 200 . When it is determined that the photosensor 3b has not detected the IC card 200, step S3 is repeated. That is, the conveyance of the IC card 200 in the arrow A direction as shown in FIG. 6 is continued until the photosensor 3b detects the IC card 200 . Then, when it determines with the photosensor 3b having detected the IC card 200, it will transfer to step S4.

In step S4, by stopping the driving of the motor 5, the normal rotation of the conveyance rollers 2a-2c is stopped. Next, in step S5 , the electromagnet 14 b (see FIG. 4 ) is energized. As a result, as shown in FIG. 7, the plunger 14a is driven in the arrow B direction, so that the arm 15 rotates in the C direction around the rotation shaft 12e in the state where the engaging pin 14c is engaged with the notch 15a. The movable part 11 is pressed down by the arm 15 . At this time, since the IC card 200 is located below the movable member 11 , the neutralizing brush 11 f is in contact with the surface of the IC card 200 . Thereby, as shown in FIG. 8 , the region R1 on the surface of the IC card 200 is destaticized by the deionizing brush 11 f (see FIG. 7 ). At this time, the movable member 11 is located closer to the arrow B direction side than the external terminal 200 a of the IC card 200 in plan view. In addition, the width W1 of the neutralizing brush 11 f (movable member 11 ) is larger than the width W2 of the external terminal 200 a.

Next, in step S6 of FIG. 5 , the conveying rollers 2 a to 2 c are reversed by driving the motor 5 . Thereby, as shown in FIG. 9 , the IC card 200 is conveyed in the ejection direction (arrow B direction) in a state where the neutralizing brush 11 f is in contact with the card surface.

Next, in step S7, it is judged whether the optical sensor 3a (refer FIG. 9) detected the IC card 200 or not. When it is determined that the photosensor 3a has not detected the IC card 200, step S7 is repeated. That is, the conveyance of the IC card 200 in the arrow B direction as shown in FIG. 9 is continued until the optical sensor 3 a detects the IC card 200 .

Here, as shown in FIG. 10, when the IC card 200 passes under the contact block 4 and leaves the neutralizing brush 11f, the electromagnet 14b is continuously energized, and the plunger 14a is further moved from the state shown in FIG. The direction of arrow B is driven, so the arm 15 is further rotated in the direction of C. Therefore, since the movable member 11 is further pushed down by the arm 15, the claw part 11a of the movable member 11 protrudes downward so that the conveyance path P may be blocked. Then, since the IC card 200 is conveyed in the direction of the arrow B in the state where the static elimination brush 11f is in contact with the card surface, as shown in FIG. . That is, in the card reader 100 of this embodiment, only a part (region R2 ) of the surface of the IC card 200 is destaticized, and the entire external terminal 200 a of the IC card 200 is destaticized.

When it is judged in step S7 of FIG. 5 that the photosensor 3a has detected the IC card 200, it will transfer to step S8. In step S8, by stopping the drive of the motor 5, the reverse rotation of the conveyance rollers 2a-2c is stopped. Next, in step S9, by driving the motor 5, the conveyance rollers 2a-2c are rotated normally. Thereby, as shown in FIG. 12, the IC card 200 is conveyed in the arrow A direction again.

Then, as shown in FIG. 10, since the claw portion 11a of the movable member 11 protrudes toward the transport path P, the tip of the IC card 200 conveyed in the arrow A direction abuts against the claw portion 11a. If the IC card 200 is further conveyed in the direction of arrow A while maintaining this abutting state, a pressing force based on the conveying force of the card is applied from the front end of the IC card 200 to the claw portion 11a, so the movable member 11 resists stretching. The coil spring 13 is biased to move. That is, the shafts 11c, 11d of the movable member 11 are respectively guided by the guide holes 12c, 12d, so that the movable member 11 moves along the guide holes 12c, 12d. When the shafts 11c, 11d reach the position shown in FIG. stop. During this process, the contact terminal 11 e of the movable member 11 comes into contact with the external terminal 200 a (see FIG. 14 ) of the IC card 200 . The external terminal 200 a is electrically connected to an IC chip (not shown) built in the IC card 200 . Card information and transaction information are stored in the IC chip.

Next, in step S10 of FIG. 5 , the normal rotation of the transport rollers 2 a to 2 c is stopped by stopping the drive of the motor 5 . Thereby, the IC card 200 stops with the contact terminal 11e in contact with the external terminal 200a. In addition, the timing of stopping the drive of the motor 5 is determined based on, for example, the detection result of an optical sensor not shown. Alternatively, the timing at which the motor stops may be determined based on the elapsed time from the start of normal rotation of the transport rollers 2 a to 2 c in step S9 or the rotation speed of the motor 5 .

Next, in step S11, communication between the IC card 200 and the control unit 6 is performed through the contact terminal 11e and the external terminal 200a. Thereby, information stored in the IC card 200 is read or updated. In addition, communication is also performed between the control unit 6 and the host device 150 (see FIG. 4 ).

Next, in step S12, energization to the electromagnet 14b is stopped. As a result, the plunger 14a is reset in the arrow A direction from the state shown in FIG. 13 by a return spring (not shown), so the arm 15 is rotated in the D direction around the rotation shaft 12e. As a result, the movable member 11 is released from the depression of the arm 15 . Then, in step S13 , the conveying rollers 2 a to 2 c are reversed by driving the motor 5 . Thus, the IC card 200 is conveyed in the arrow B direction, and the front end of the IC card 200 is separated from the claw portion 11a, so the movable member 11 is received in the bracket 12 by the biasing force of the tension coil spring 13, and the contact block 4 returns. to the original state shown in Figure 3.

Next, in step S14, it is determined whether or not the IC card 200 has been ejected. Card ejection can be detected by, for example, a sensor (not shown) provided near the insertion port 1a. In addition, instead of the above-described detection, the ejection of the card may be detected by measuring the elapsed time from the start of the reverse rotation of the transport rollers 2 a to 2 c or the rotation speed of the motor 5 . When it is determined that the IC card 200 has not been ejected, step S14 is repeated. That is, the conveyance of the IC card 200 in the arrow B direction shown in FIG. 15 is continued until the IC card 200 is ejected. Then, when it is judged that the IC card 200 has been ejected, it will transfer to step S15.

In step S15, by stopping the drive of the motor 5, the reverse rotation of the conveying rollers 2a-2c is stopped, and a series of operation|movement is finished after that.

As described above, in this embodiment, the static eliminating brush 11f is provided on the movable member 11, and before the contact terminal 11e contacts the external terminal 200a of the IC card 200, only the region R2 including the external terminal 200a (see FIG. ) to eliminate static electricity, compared to the case where the static elimination brush is always in contact with the surface of the IC card, abrasion of the static elimination brush 11f can be suppressed. Accordingly, it is possible to reduce the occurrence of electrical malfunctions caused by scattering of the abrasion powder of the neutralizing brush 11f in the housing 1 . Moreover, scratches on the surface of the IC card 200 can also be suppressed by 11 f of static elimination brushes.

In addition, in the present embodiment, the movable member 11 is pressed down by the arm 15, whereby the neutralizing brush 11f is brought into contact with the surface of the IC card 200. When the direction perpendicular to the extending direction of the IC card 200 is in contact with the anti-static brush, even if there is a crack on the side of the IC card 200, the hairs of the anti-static brush 11f are not easily caught in the crack, so the hairs of the anti-static brush 11f can be prevented from being caught. pull off.

In addition, in this embodiment, as shown in FIG. 11 , since the region R2 including the external terminal 200a of the IC card 200 is destaticized, all the terminals (ground terminals and signal terminals) constituting the external terminal 200a can be removed at once. Perform static elimination.

In addition, in this embodiment, by attaching the anti-static brush 11f to the movable member 11 provided with the contact terminal 11e, the anti-static brush 11f can be moved by the movable member 11, and there is no need to separately provide a device for driving the anti-static brush 11f. Mechanism parts, so the increase in the number of parts can be suppressed accordingly.

In addition, in this embodiment, after the claw portion 11a of the movable member 11 is protruded to the conveyance path P by the driver 14, the claw portion 11a is pressed by the IC card 200 by the conveying force of the IC card 200, so that the contact terminal 11e and The external terminals 200a are in contact. Therefore, compared with the case where the contact terminal 11e is brought into contact with the external terminal 200a by the driving force of the driver, it is possible to reduce the size and power consumption of the driver 14 .

The present invention can employ various embodiments other than those described above. For example, in the case of a card reader that processes an IC card with a magnetic stripe, set the magnetic head (not shown) in the above-mentioned embodiment, and read the magnetic head when the IC card in step S2 in FIG. 5 is conveyed. Get the information on the magnetic stripe.

In addition, in the above-mentioned embodiment, the example in which the anti-static brush 11f is provided on the movable member 11 configured to make the contact terminal 11e contact the external terminal 200a by the transmission force of the IC card 200 is shown, but the present invention is not limited thereto. An anti-static brush may be provided on a movable member configured to bring the contact terminal 11e into contact with the external terminal 200a by direct driving of a driver.

In addition, in the above-mentioned embodiment, the example in which the energization of the electromagnet 14b is stopped (step S12) after the communication between the card reader 100 and the IC card 200 is shown, but it is not limited to this, and the energization of the electromagnet 14b The stop may be any time after the contact terminal 11e comes into contact with the external terminal 200a.
