본 발명은 카드식 공중전화기등과 같이 자기카드를 사용하는 각종기기에서 카드내의 데이타를 처리하는 카드리더에 유사카드가 인입되는 것을 방지하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing the like card from being inserted into a card reader that processes data in a card in various devices using a magnetic card such as a card type public telephone.

구체적으로는 유사카드를 감지하는 센서와 센서의 신호를 받아 선택적으로 작동하는 셔터, 이 셔터를 작동시키는 솔레노이드로 구성되어 있어 유사카드는 인입될 수 없고, 일단 인입된 카드는 셔터를 구동시키는 장치의 고장시에도 무리없이 카드를 배출시킬 수 있도록 된 유사카드 인입방지장치에 관한 것이다.Specifically, it is composed of a sensor that detects a similar card, a shutter that selectively operates by receiving a signal from the sensor, and a solenoid that operates the shutter, so that the similar card cannot be inserted, and the card once inserted is a device of a device that drives the shutter. It relates to a similar card pull-out prevention device that can be ejected without difficulty even in the event of a failure.

종래의 카드리더에 부착된 유사카드 인입방지장치는 인입과 배출시 공히 셔터를 작동하도록 되어 있어 일단 인입될 카드가 데이타처리후 배출될때 기기의 고장 및 기타 사유로 셔터작동기구가 제기능을 발휘하지 못하는 경우 카드리더 내부에 카드가 잔존하고 외부로 배출되지 않아 사용자의 불만과 민원발생의 소지가 되었을 뿐만 아니라 기기의 고장원인 되었다.The conventional card reader prevention device attached to the card reader is designed to operate the shutter when both the card is inserted and ejected so that the shutter mechanism does not function properly due to a malfunction or other reasons when the card to be ejected is ejected after data processing. If not, the card remained inside the card reader and was not ejected to the outside, causing user complaints and complaints as well as causing the device to malfunction.

본 발명은 이와 같은 제반결점을 제거하기 위하여 창출된 것으로서 자기카드의 유사여부를 감지하여 인입을 결정하고 일단 인입된 카드는 투입구의 카드 감지장치의 오동작이나 고장에 관계없이 카드를 무리없이 외부로 배출시킬수 있도록 하는데 목적이 있는 것이다.The present invention was created to eliminate such defects, and determines whether the magnetic card similarity is detected, and once the card is inserted, the card is ejected to the outside without difficulty regardless of the malfunction or failure of the card detection device of the inlet. The purpose is to make it possible.

이와같은 목적을 달성하기 위한 본 발명의 특징은 카드가 인입될때는 센서로 감지하여 인위적으로 셔터가 열리도록 하고, 배출될때는 카드의 배출되는 힘에 의해 자연적으로 셔터가 열리도록 한 것으로서 그 구성을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.A feature of the present invention for achieving the above object is that the shutter is artificially opened by detecting the sensor when the card is inserted, and the shutter is naturally opened by the ejecting force of the card when it is ejected. When described in detail based on the accompanying drawings as follows.

제1도는 본 발명의 사용상태도이고, 제2도는 본 발명의 사시도이며 제3도는 본 발명의 작동상태도로서 투입구(7)의 일측에 카드(10) 투입여부를 감지하는 센서(6)가 부착되고, 그 내측으로 핀치롤러(4)와 카드(10)의 진위를 감지하는 자기헤드(5)가 상하로 장착되며, 후방으로는 일측에 솔레노이드(3)와 접촉되어 셔터(1)를 개폐시키는 경사판(8)이 돌출된 셔터(1)의 좌우 양측에 피봇(2,2)을 중심으로 회동되게 고정한다. 이때 셔텨(1)의 종단면 형상은 인입되는 카드(10)의 표면과 직각을 이루도록 앞면이 형성되고, 배출되는 카드(10)의 표면과 약간의 경사를 이루도록 밑면(1′)이 형성되며, 셔텨(1)의 상단에는 셔텨(1)가 열릴때 완충될 수 있도록 완충용 스프링(9)을 부착한다. 미 설명부호 11은 카드리더, 12는 모터, 13은 드럼이다.1 is a state diagram of the use of the present invention, FIG. 2 is a perspective view of the present invention, and FIG. 3 is an operation state diagram of the present invention, wherein a sensor 6 is attached to one side of the inlet 7 to detect whether the card 10 is inserted. Inwardly, the pinch roller 4 and the magnetic head 5 for detecting the authenticity of the card 10 are mounted up and down, and the rear side is inclined to contact the solenoid 3 on one side to open and close the shutter 1. (8) is fixed to the left and right sides of the protruding shutter (1) so as to rotate about the pivot (2,2). At this time, the longitudinal cross-sectional shape of the shutter 1 is formed so that the front surface is perpendicular to the surface of the card 10 to be inserted, and the bottom surface 1 'is formed to form a slight inclination with the surface of the card 10 to be discharged. At the top of (1), a shock absorbing spring (9) is attached to the shock absorber when the shutter (1) is opened. Reference numeral 11 denotes a card reader, 12 a motor, and 13 a drum.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다. 자기카드(10)가 투입구(7)를 통해 투입되면 제3a도에 도시된 바와 같이 카드(10)가 셔터(1)에 의해 인입이 정지되게 되는데 이때 감지센서(6)에 의해 카드(10) 투입이 감지되고 이 신호가 핀치롤러(4) 하부에 설치되어 있는 자기헤드(5)를 작동시켜 인입된 카드(10)의 유사여부를 판독한다. 그래서 헤드(5)에서의 감지신호에 의해 카드가 정상카드로 감지되면 제3b도와 같이 측벽에 설치되어 있는 솔레노이드(3)를 작동시켜 셔터(1)의 측면에 돌출되어 있는 경사판(8)의 경사를 따라 밀어줌으로 셔터(1)가 피봇(2,2′)을 중심으로 회전하여 열리게되어 카드리더(11) 내부로 카드(10)가 인입된다. 또한 경사판대신에 셔터에 지지판등을 설치하여 지지판을 솔레노이드로 들어 올리거나 밀어올려 피봇을 중심으로 셔터를 회전시켜 열리게 할 수도 있다.Referring to the effect of the present invention configured as described above are as follows. When the magnetic card 10 is inserted through the inlet 7, the card 10 is stopped by the shutter 1 as shown in FIG. 3a. At this time, the card 10 is detected by the sensor 6. Input is sensed, and this signal reads the similarity of the inserted card 10 by operating the magnetic head 5 installed under the pinch roller 4. Thus, when the card is detected as a normal card by the detection signal from the head 5, the inclination of the inclined plate 8 protruding to the side of the shutter 1 by actuating the solenoid 3 installed on the side wall as shown in FIG. By sliding along the shutter 1 is rotated about the pivot (2, 2 ') is opened to open the card 10 into the card reader (11). In addition, a support plate may be installed in the shutter instead of the inclined plate to lift or push the support plate by the solenoid to rotate the shutter about the pivot to open.

이와 같이 카드리더(11) 내부로 카드(10)가 인입되면 제3b도와 같이 카드리더(11)내의 신호에 의해 솔레노이드(3)가 후퇴되면 셔터(1)가 자중에 의해 닫히게 된다. 그리고 카드리더(11) 내부에서 인입된 카드(10)에 대한 소정의 처리가 완료되면 카드리더내의 모터(12) 및 드럼(13)의 역회전에 의해 자기 카드는 인입시와는 반대로 처음 투입구(7)로 배출하게 되는데 이때 자기카드(10)는 셔터(1)의 경사진 밑면(1′)을 따라 배출되면서 반송력으로 밀어주게 되어 셔터(1)는 피봇(2,2′)을 중심으로 자연스럽게 열리게 되므로 솔레노이드(3)등 자기의 오동작에 관계없이 카드(10)가 배출된다.When the card 10 is inserted into the card reader 11 as described above, when the solenoid 3 is retracted by the signal in the card reader 11 as shown in FIG. 3B, the shutter 1 is closed by its own weight. When the predetermined processing of the card 10 inserted in the card reader 11 is completed, the magnetic card is inserted into the first slot through the reverse rotation of the motor 12 and the drum 13 in the card reader. 7) The magnetic card 10 is discharged along the inclined bottom 1 'of the shutter 1 and is pushed by the conveying force so that the shutter 1 is centered on the pivots 2 and 2'. Since it opens naturally, the card 10 is discharged regardless of the malfunction of the solenoid 3 or the like.

이와같은 방법은 유사카드 여부를 감지하여 인입여부를 결정하고 일단 인입된 카드는 솔레노이드의 오동작 또는 고장의 관계없이 카드를 무리없이 외부로 배출시킬 수 있는 효과가 있는 발명인 것이다.Such a method is to determine whether the card is inserted by detecting whether or not a similar card, and once the card is inserted, the invention has the effect that the card can be discharged to the outside without difficulty regardless of malfunction or failure of the solenoid.
