Abstract

PURPOSE: A mobile terminal available for text recognition by using a sense of touch is provided to allow the eye-handicapped to receive a text service by recognizing a text message. CONSTITUTION: An electric signal line(11) receives data, namely, a switch signal that has been converted from a character signal by a board, and provides it to an electromagnet(12). The electromagnet(12) is repeatedly turned on/off according to the switch signal. A sign transfer member makes a mechanical reciprocal movement toward a touch pad according to ON/Off of the electromagnet(12). A sign transfer guide member(14) guides and limits the reciprocal movement of the sign transfer member(13). A sign transfer member recovering spring(15) recovers the signal transfer member(13) when the electromagnet(12) is OFF. The touch pad(16) is touched by a user.

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

상기와 같은 본 발명 촉각을 이용하여 문자인식이 가능한 휴대용 단말기는 다음과 같은 작용 효과를 가진다.The portable terminal capable of character recognition using the present invention as described above has the following effects.

즉, 시각장애인이 휴대용 단말기를 이용하여 문자서비스를 받으려고 할 때 사용자는 단말기덮개(2)의 안쪽 외측면에 구비한 터치패드(16)에 손가락을 대고 그 손가락에 전해지는 단점부호와 장점부호를 문자 또는 기호로 인식하여 정보를 제공받을 수 있다.That is, when a visually impaired person tries to receive text service using a portable terminal, the user places a finger on the touch pad 16 provided on the inner and outer surface of the terminal cover 2, and the disadvantage code and the advantage code transmitted to the finger. Information can be provided by recognizing it as a letter or symbol.

이를 보다 상세히 살펴 보면, 기판(미도시)에서 수신한 문자 데이터를 단락 신호 데이터로 변환한 후에 이를 전기신호선(11)을 통해 전자석(12)으로 전달한다. 이를 전달받은 전자석(12)은 단점부호와 장점부호를 구분하면서 온/온프 동작하고, 이 전자석(12)의 온/오프 동작에 따라 부호전달부재(13)가 전자석(12)과 터치패드(16) 사이를 왕복하면서 터치패드(16)에 단점부호와 장점부호를 전달한다.Looking at this in more detail, after converting the character data received from the substrate (not shown) to the short-circuit signal data it is transmitted to the electromagnet 12 through the electrical signal line (11). The received electromagnet 12 is on / off operation while distinguishing the disadvantage code and the advantage code, the code transfer member 13 according to the on / off operation of the electromagnet 12, the electromagnet 12 and the touch pad 16 The reciprocal code and the sympathy code are transmitted to the touch pad 16 while reciprocating between them.

이때, 부호전달안내부재(14)와 전달봉(13b)의 스프링지지돌기(13c) 사이에 압축스프링인 부호전달부재복귀스프링(15)을 고정함에 따라 전자석(12)이 온 동작을 수행할 때는 부호전달부재(13)가 전자석(12)쪽으로 이동하여 터치패드(16)에서 이격되는 반면 전자석(12)이 오프 동작을 수행할 때는 자력이 제거되면서 부호전달부재(13)가 상기한 부호전달부재복귀스프링(15)의 복원력에 의해 터치패드(16)쪽으로 이동하면서 이 터치패드(16)를 때려 소정의 부호를 전달하는 것이다.At this time, when the electromagnet 12 is turned on by fixing the code transfer member return spring 15, which is a compression spring, between the code transfer guide member 14 and the spring support protrusion 13c of the transfer rod 13b. While the code transfer member 13 moves toward the electromagnet 12 and is spaced apart from the touch pad 16, when the electromagnet 12 performs the off operation, the magnetic force is removed and the code transfer member 13 is moved. The predetermined force is transmitted to the touch pad 16 by the restoring force of the return spring 15 to strike the touch pad 16 and transmit a predetermined code.

또, 부호전달부재(13)는 부호전달안내부재(14)의 부호전달부재관통구멍(14a)에 삽입된 상태에서 왕복운동을 함에 따라 항상 직선으로 이동한다.Further, the code transfer member 13 always moves in a straight line as the code transfer member 13 reciprocates while being inserted into the code transfer member through hole 14a of the code transfer guide member 14.

본 발명에 의한 촉각을 이용하여 문자인식이 가능한 휴대용 단말기는, 문자데이터를 단락 신호로 변환하여 전자석에 전달하고 이 단락 신호에 따라 전자석에 착탈하는 신호전달부재를 감지하여 모스 부호로 인식할 수 있는 점자표시장치를 구성함으로써, 시각장애인도 휴대용 단말기를 통해 각종 문자서비스를 제공받을 수 있다.The portable terminal capable of character recognition using the tactile sense according to the present invention converts the character data into a short signal and transmits it to an electromagnet, and detects a signal transmission member detachable from the electromagnet according to the short signal and recognizes it as a Morse code.
