Description

IC card reader with improved contact efficiency

The present invention relates to a reading device for reading an IC card, and more particularly, a contact head contacted with a contact terminal of the IC card to read card information maintains an appropriate pressing force and is generated by bending the IC card. The present invention relates to an IC card reader having improved contact performance for preventing contact failure and resulting reading errors.

In general, a magnetic stripe card (hereinafter referred to as a magnetic card) that forms a magnetic stripe made of a magnetic material on the back of a card formed of a synthetic resin and stores unique information for identifying an individual by changing a magnetic field on the magnetic stripe. In many industries, such as automated teller machines, access control devices, cash registers, etc., it is widely used as a means for identifying whether a user who uses the device is a person authorized by right.

Such a magnetic card is used to read information stored in the magnetic stripe, and a dedicated reading device is used. For example, in an automatic teller machine or the like, when the user inserts the magnetic card into an opening of a reading device exposed on one side of the automatic teller machine, the reading device is used. The conveying means inside operates the magnetic stripe in contact with the reading head as the magnetic stripe is contacted with the reading head to detect the information stored in the magnetic stripe by changing the magnetic field, or the user directly reads the magnetic stripe of the magnetic stripe for reading the reading device. It contacts the head to sense the information contained in the magnetic stripe.

In recent years, following the magnetic card, there is little risk of duplication compared to the magnetic card, and the use of IC cards (or smart cards), which have a very large memory capacity, high functionality and stability, has been gradually expanded. As shown in FIG. 1, the IC card 1 has an IC chip (not shown) embedded in a synthetic resin card, and an external surface of the card is used for electrical contact between the IC chip and an external reading device. The connection terminals 2 are exposed.

When the IC card 1 is inserted into the inlet of the reading apparatus, the conveying means in the reading apparatus is operated in the same manner as described above, and the IC card 1 is introduced into the apparatus and the IC card 1 is drawn to a fixed position and stopped. Then, the contact head (not shown in the drawing) of the reading device is in pressure contact with the connection terminal 2 to read data stored in the IC chip.

However, in the IC card, unlike the information stored in the magnetic sprite as the magnetic card is transferred, the contact head is pressed in contact with the connection terminal 2 while the magnetic card is transferred to a predetermined position and stopped. Since the contact head is not easy to maintain an appropriate pressing force on the connection terminal 2 so that the contact head has an optimal read performance, the card may be bent.

In other words, the IC card is a thin and light product, so it may be inserted in a curved state from the time of being input by the first user, and when a part where the connection terminal 2 is formed by the contact head is pressed, a part of the total area is pressed. Since it is in a state of being bent, it is curved in one direction or in a long direction. If the portion where the connection terminal of the IC card is installed is curved, the contact performance with the contact head is seriously degraded, and thus the reading performance is also reduced.

Therefore, the present invention is intended to provide an IC card reader configured to contact the contact head of the appropriate pressing force is maintained in contact with the connection terminal of the IC card introduced into the card reader, and configured to cope with the curved card. There is this.

The present invention for achieving the above object, the upper and lower guides for guiding the upper and lower surfaces of the IC card to be inserted into the card inserting portion, the upper surface guide and the lower surface guide between the lower surface guide is installed on the drive path and the drive motor A plurality of rollers for incoming or outgoing transfer of IC cards by power transfer, and contact heads which are installed on the upper side of the card transfer path and stoppers protruding the front end of the IC card at the bottom end to guide the correct position of the IC card connection terminal. A contact head bracket having an elastic member provided on both sides thereof with a slide hole in which guide protrusions protruding from both sides of the contact head are inclined downward in an inlet and transfer direction of the IC card, while providing upward attraction to the contact head; The contact is driven by driving a link connecting member coupled to the contact head bracket. It has a structure including a solenoid for elevating the head.

In the above, the bottom guide is characterized in that the protruding step is formed to protrude upward to the portion facing the contact head to support the back of the portion where the connection terminal of the IC card is formed.

Hereinafter, the configuration and the effect according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view of an IC card reading apparatus for improving contact performance according to an embodiment of the present invention, and FIGS. 3A to 3C are IC cards of an IC card reading apparatus for improving contact performance according to an embodiment of the present invention. A schematic side view for explaining the processing operation.

The IC card reader which improves the contact performance according to the embodiment of the present invention is a device for processing the IC card 1 as described in the prior art.

The IC card 1 is inserted with the connection terminal 2 facing upward to the card insertion section 10 side.

For example, a shutter (not shown) may be installed in the card input unit 10 to prevent the inflow of dust.

The IC card 1 inserted into the card insertion unit 10 is guided by an upper surface guide 25 and a lower surface guide 26 installed inside the device, while between the upper surface guide 25 and the lower surface guide 26. The retraction transfer is advanced by the plurality of rollers 23a, 23b, 23c, 24a, 24b, and 24c provided on the card transfer path.

The rollers 23a, 23b, 23c, 24a, 24b, and 24c are the outer edges of the feeding rollers 23a, 23b, 23c and the respective feeding rollers 23a, 23b, 23c, which receive rotational driving force from the drive motor 20. It is divided into idle rollers (24a, 24b, 24c) to be in contact with the lower portion, and installed at intervals less than the longitudinal length of the card in the card insertion direction.

Looking at the power transfer process from the drive motor 20 to each feeding roller (23a, 23b, 23c), the drive pulley 20a is coupled to the drive shaft (not shown) of the drive motor 20, drive pulley 20a is belt-connected by the first pulley 22a and the first power transmission belt 21a formed in a plurality of rows. Therefore, the first feeding roller 23a is coupled to the same shaft as the first pulley 22a and thus receives power transmission.

The first pulley 22a is belt-connected by the second pulley 22b and the second power transmission belt 21b, while the first pulley 22a formed in a plurality of rows is the third pulley 22c and the third pulley. The belt is connected by the belt 21c. Therefore, the second feeding roller 23b is coupled to the same shaft as the second pulley 22b and thus is powered. The third feeding roller 23c is coupled to the same shaft as the third pulley 22c and is thus transmitted. .

As such, the rotational driving force of the driving motor 20 is provided to each of the feeding rollers 23a, 23b, and 23c, and each of the feeding rollers 23a, 23b, and 23c is rotated by contacting the outer edge of the idle rollers 24a, In conjunction with 24b and 24c, the IC card 1 is retracted or unloaded according to the forward and reverse rotation of the drive motor.

In addition, the IC card 1 inserted into the card input unit 10 is connected to the contact terminal 2 which is installed on the upper side of the card transfer path. When the transfer is carried out or the defective card is generated, the feed roller 23c and the idle roller 24c which are installed at the rear end of the card transfer path so that the defective card is collected are continuously transferred and recovered. That is, the feeding roller 23c and the eye roller 24c provided at the rearmost end of the card conveyance path are rollers for advancing the card to recover the defective card.

On the other hand, instead of the rollers 23a, 23b, 23c, 24a, 24b, 24c conveying device is a belt conveying device may be implemented.

The contact head 40 is a device for reading the information of the IC card 1 in contact with the connection terminal 2 of the IC card 1, which is provided above the card transfer path and at the bottom end of the IC card 1 A stopper 41 which protrudes from the front end of the IC card 1 to guide the correct position of the connection terminal 2 is formed.

The contact head 40 is installed in the contact head bracket 50, which is vertically conveyed by the link member 60 coupled with the solenoid 70, and the IC card 1 has the rollers 23a and 23b described above. , 24a and 24b are moved downwards to be in pressure contact with the connection terminal 2 of the IC card 1.

The contact head bracket 50 has slide holes 51 formed on both sides of which the guide protrusions 42 protruding from both sides of the contact head 40 are inserted and inclined downward in the conveying direction of the IC card 1.

The contact head bracket 50 is coupled to the other end of the elastic member 52 having one end coupled to the contact head 40.

Accordingly, the contact head 40 is positioned at the top of the contact hole 42 along the slide slot 51 of the contact head bracket 50 by the attraction force of the elastic member 52 before the IC card 1 is inserted.

In addition, the contact head 40 and the contact head bracket 50 are coupled to the link member 60 which is link-switched according to the driving of the solenoid 70 and is vertically conveyed.

The link member 60 is pivoted about the pivot shaft 61a, and one side of the pivot bracket 61 is assembled with the driving shaft 71 of the solenoid 70, and assembled with the other side of the pivot bracket 61 and the contact head bracket. It consists of a contact head lifting shaft 62 projecting upward from the upper surface of the 50.

As shown in the drawing, the turning bracket 61 has a locking groove 61b in which a locking pin 71a protruding from the driving shaft 71 of the solenoid 70 is assembled to the lower side of the turning shaft 61a. On the right side of 61a), a locking groove 61c in which the locking pin 62a protruding from the contact head lifting shaft 62 is assembled is formed.

Therefore, before the IC card 1 is introduced into the apparatus, as shown in FIG. 3A, the driving shaft 71 of the solenoid 70 protrudes as much as possible, and the pivot bracket 61 is not pivoted, and the contact head is not in contact. 40 and the contact head bracket 50 are raised so that the stopper 41 of the contact head 40 does not enter the card transfer path.

In this state, when the IC card 1 is introduced into the apparatus, the driving shaft 71 of the solenoid 70 is sucked as shown in FIG. 3B, and the turning bracket 61 is counterclockwise around the turning shaft 61a. Direction, the contact head 40 and the contact head bracket 50 are lowered so that the stopper 41 of the contact head 40 partially enters the card transfer path to block the advance of the IC card 1. do. However, even in this state, the connection terminal 2 of the IC card 1 is not in contact with the contact head 40.

And even if the front end of the IC card 1 in contact with the stopper 41 of the contact head 40, as shown in Figure 3b, if the drive motor 20 is further driven with a slight margin by the set value, As shown in 3c, the stopper 41 of the contact head 40 blocks the front end of the IC card 1, so that the contact head 40 overcomes the attraction of the elastic member 52 and together with the IC card 1; Since the guide head 42 of the contact head 40 is inclined downward along the slide slot 51 of the contact head bracket 50, the contact head 40 is lowered to connect the IC card 1. It comes into contact with the terminal 2.

In this way, the contact head 40 has a contact head 40 because the pressing force applied to the connection terminal 2 is properly adjusted between the restoring force of the elastic member 52 and the transfer force of the IC card 1 by the driving motor 20. Since the pressing force is maintained to be constant, the contact performance is improved, thereby improving the read performance.

In addition to the above configuration, the lower surface guide 26 protrudes upward from a portion facing the contact head 40 to protrude and support the rear surface of the portion where the connection terminal 2 of the IC card 1 is formed ( 30) is formed.

The protruding step 30 is the transfer of the IC card 1 is bent in the longitudinal or transverse direction from the beginning, or the contact head 40 pressurizes the connection terminal 2 to bend the IC card 1 This is to prevent the occurrence of poor contact and the resulting deterioration in read performance.

In other words, even when the IC card 1 is curved, the connection terminal 2 of the IC card 1 convexly protrudes the position of the rear guide 26 corresponding to the correct position for reading, thereby making the IC card 1 It is to improve the contact performance between the connection terminal 2 and the contact head 40 of the.

Specifically, the protruding step 30 is the inclined portion 31 which is formed to be inclined upward in the incoming transfer direction of the IC card 1, the horizontal extension at the top end of the inclined portion 31 is the IC card (1) connecting terminal (2) The rear of the support is made of a support (32). Thus, the IC card 1 is seated on the support 32 along the inclined portion 31 without a transfer resistance.

As described above, the present invention improves contact performance and read performance since the contact head is not only in contact with the IC card connection terminal while maintaining an appropriate pressing force, but also the back side of the connection terminal is pressed against the protruding end to correspond to card curvature. There is an advantage.
