Description

필기감을 조절하는 스타일러스 펜Stylus pen to control writing
본 발명은 디지타이저에 이용되는 스타일러스 펜에 관한 것으로, 보다 상세하게는 사용자의 터치 스크린에 대한 입력 필기감을 조절하는 것이 가능한 스타일러스 펜팁에 관한 것이다. The present invention relates to a stylus pen used in a digitizer, and more particularly, to a stylus pen tip capable of adjusting an input writing feeling on a user's touch screen.
디지타이저(Digitizer)는 디스플레이 기기에 사용되는 입력 장치의 한 종류로서, 매트릭스 형태의 전극 구조를 포함하고, 사용자가 펜 또는 커서를 움직이면 매트릭스 상의 X, Y 좌표를 읽어 입력 장치의 위치 신호를 전달하고, 그에 해당되는 명령을 수행하는 장치이다. Digitizer is a type of input device used in display devices, and includes an electrode structure in the form of a matrix, and when a user moves a pen or a cursor, the digitizer reads the X and Y coordinates on the matrix and transmits a position signal of the input device. It is a device that performs the corresponding command.
종래 기술에 따른 디지타이저의 스타일러스 펜은 교환형 펜팁을 적용하는 제품 및 일체형 펜팁을 적용하는 제품으로 분류될 수 있다. The stylus pen of the digitizer according to the prior art may be classified into a product to which an interchangeable pen tip is applied and a product to which an integrated pen tip is applied.
디지타이저 제품의 특성상, 스타일러스 펜팁과 맞닿는 터치 스크린은 유리 또는 플라스틱 등 마찰력이 적고 미끄러운 재질로 형성된다. Due to the characteristics of the digitizer product, the touch screen in contact with the stylus pen tip is made of a slippery material with low friction such as glass or plastic.
종래 기술에 따른 디지타이저용 스타일러스 펜 중 교환형 펜팁 구조는 도 1에 도시된 바와 같이 하우징(10) 내에 교환형 팁(100)이 배치되고, 그 끝부분이 실리콘팁(110)으로 형성된다. 이러한 실리콘팁(110)은 사용에 따라 마모되기 때문에, 주기적으로 스타일러스 펜 팁을 교환해주어야 하는 불편함이 있다. 또한, 사용자는 이러한 실리콘팁(110)을 이용하여 유리 또는 플라스틱 재질의 터치 스크린 상에 글씨를 쓰거나 그림을 그리는 경우, 그 필기감이 현저히 떨어지는 문제점이 있다. In the interchangeable pen tip structure of the stylus pen for digitizer according to the prior art, the replaceable tip 100 is disposed in the housing 10 as shown in FIG. 1, and an end thereof is formed of a silicon tip 110. Since the silicon tip 110 wears with use, there is an inconvenience in that the stylus pen tip needs to be replaced periodically. In addition, when the user writes or draws letters on the glass or plastic touch screen using the silicon tip 110, the writing feeling is remarkably inferior.
종래 기술에 따른 디지타이저용 스타일러스 펜 중 일체형 펜팁 구조는 도 2에 도시된 바와 같이, 플라스틱 일체형 펜팁(20)으로 구성되나, 이러한 경우 펜팁은 플라스틱 재질로 형성되므로, 유리 또는 플라스틱 재질의 터치 스크린 상에 입력 신호를 가할 경우, 마찰력이 거의 없어 과도하게 미끄러짐으로써, 사용자는 이질적인 필기감을 느끼는 문제점이 있다. The one-piece pen tip structure of the stylus pen for digitizer according to the prior art is composed of a plastic integral pen tip 20, as shown in Figure 2, in this case, since the pen tip is formed of a plastic material, on a touch screen of glass or plastic material When the input signal is applied, there is little friction, so that the user slides excessively, so that the user feels a heterogeneous writing feeling.
본 발명의 목적은 사용자의 필요에 따라서, 스타일러스 펜팁의 터치 스크린과 맞닿는 부위의 코팅볼 움직임의 부드러움 정도를 조절하여, 사용자에게 자연스러운 필기감을 제공하는 것이 가능한 필기감을 조절하는 스타일러스 펜을 제공하는 데 목적이 있다. An object of the present invention is to provide a stylus pen for adjusting the writing feeling that can provide a natural writing feeling to the user by adjusting the smoothness of the coating ball movement of the portion in contact with the touch screen of the stylus pen tip according to the needs of the user There is this.
본 발명의 일면에 따른 필기감을 조절하는 스타일러스 펜은 스타일러스 펜의 하우징과, 하우징 내에 배치되어 터치 스크린에 접촉되는 경우 입력 신호를 가하는 코팅볼과, 코팅볼의 상부에 접촉되어 탈거를 방지하는 자석볼 및 자석볼에 대하여 코팅볼 방향으로 가해지는 압력을 조절하여, 코팅볼의 터치 스크린에 대한 입력 필기감을 조절하는 압력 조절부를 포함하는 것을 특징으로 한다. The stylus pen for adjusting the writing feeling according to an aspect of the present invention includes a housing of the stylus pen, a coating ball disposed in the housing to apply an input signal when contacting the touch screen, and a magnetic ball contacting the upper portion of the coating ball to prevent detachment. And by adjusting the pressure applied in the coating ball direction with respect to the magnet ball, characterized in that it comprises a pressure adjusting unit for adjusting the input writing feeling on the touch screen of the coating ball.
본 발명에 따른 필기감을 조절하는 스타일러스 펜은 하우징 내에 배치되는 스프링의 반발력 또는 압력 센서의 저항을 가변시켜, 사용자의 필요에 따라 상이한 필기감을 제공함으로써, 디지타이저의 터치 스크린 상에 스타일러스 펜을 이용하여 입력하는 경우 자연스러운 필기감을 제공하는 것이 가능한 효과가 있다. The stylus pen for adjusting the writing feeling according to the present invention varies the repulsive force of the spring disposed in the housing or the resistance of the pressure sensor, thereby providing a different writing feeling according to the user's needs, thereby inputting using the stylus pen on the touch screen of the digitizer. In this case, it is possible to provide a natural writing feeling.

이하에서는, 본 발명의 실시예에 따른 필기감을 조절하는 스타일러스 펜에 대하여, 스프링을 이용한 방식으로서 제1 실시예를 설명하고, 압력 센서를 이용한 방식으로서 제2 실시예를 설명한다. Hereinafter, the first embodiment will be described as a method using a spring, and the second embodiment will be described as a method using a pressure sensor for the stylus pen for adjusting the writing feeling according to the embodiment of the present invention.
먼저, 도 3 내지 도 5에 관한 상세한 설명으로 제1 실시예를 설명하고, 도 6에 관한 상세한 설명으로서 제2 실시예를 설명하기로 한다. First, the first embodiment will be described with reference to FIGS. 3 to 5, and the second embodiment will be described with reference to FIG. 6.
도 3 및 도 4는 본 발명의 제1 실시예에 따른 필기감을 조절하는 스타일러스 펜의 구조를 나타내는 단면도이며, 도 5는 본 발명의 제1 실시예에 따른 필기감을 조절하는 스타일러스 펜의 작동 원리를 설명하는 예시도이다. 3 and 4 are cross-sectional views showing the structure of the stylus pen for adjusting the writing feeling according to the first embodiment of the present invention, Figure 5 is a working principle of the stylus pen for adjusting the writing feeling according to the first embodiment of the present invention It is an illustrative view explaining.
본 발명의 제1 실시예에 따른 필기감을 조절하는 스타일러스 펜(300)은 하우징(390)과, 하우징(390) 내에 배치되어, 디지타이저의 터치 스크린에 접촉되는 경우 입력 신호를 가하는 코팅볼과, 코팅볼의 탈거를 방지하는 자석볼(310) 및 자석볼(310)에 대하여 코팅볼 방향으로 가해지는 압력을 조절하여, 코팅볼의 터치 스크린에 대한 입력 필기감을 조절하는 압력 조절부를 포함한다. The stylus pen 300 for adjusting the writing feeling according to the first embodiment of the present invention includes a housing 390, a coating ball disposed in the housing 390 to apply an input signal when contacted with a touch screen of the digitizer, and a coating. The magnetic ball 310 and the magnetic ball 310 to prevent the removal of the ball to adjust the pressure applied in the coating ball direction, and includes a pressure adjusting unit for adjusting the input writing feeling on the touch screen of the coating ball.
하우징(390)은 스타일러스 펜(300)의 외면을 구성하여, 코팅볼, 자석볼(310) 및 압력 조절부가 내부에 배치되며, 도 3에 도시한 바와 같이 코팅볼이 배치되는 부위를 기준으로 하향으로 그 내경이 좁아지거나, 도 4에 도시한 바와 같이 코팅볼이 배치되는 부위를 기준으로 하향으로 그 내경이 일정한 형상인 것이 가능하다. The housing 390 constitutes an outer surface of the stylus pen 300, and the coating ball, the magnet ball 310, and the pressure adjusting part are disposed therein, and are downwardly based on a portion where the coating ball is disposed as shown in FIG. 3. As a result, the inner diameter thereof may be narrowed, or as shown in FIG. 4, the inner diameter thereof may be downward in shape with respect to the portion where the coating ball is disposed.
본 발명의 제1실시예에 따르면, 자석볼(310)은 쇠구슬(370) 및 실리콘(360) 코팅 재질로 구성된 코팅볼을 자력으로 끌어당기므로, 하우징(390)이 하향으로 갈수록 그 내경이 좁아져 코팅볼의 탈거를 방지하도록 구성되거나, 하향으로 갈수록 그 내경이 일정하더라도 자석볼(310)에 의하여 코팅볼의 탈거가 방지된다. According to the first embodiment of the present invention, since the magnetic ball 310 attracts the coating ball made of the metal ball 370 and the silicon 360 coating material by magnetic force, the inner diameter of the housing 390 is downward as the housing ball 390 moves downward. The narrowing is configured to prevent the removal of the coating ball, or even if the inner diameter of the downward downward is constant, the removal of the coating ball by the magnet ball 310 is prevented.
본 발명의 제1실시예에 따른 코팅볼은 사용자의 스타일러스 펜 입력에 따라 회전되므로, 종래 기술에 따른 일체형 또는 교체형 펜팁에 비하여 그 마모도가 현저히 감소된다. Since the coated ball according to the first embodiment of the present invention is rotated according to the user's stylus pen input, its wear is significantly reduced compared to the integrated or replaceable pen tip according to the prior art.
