Among the pointing devices, a pointing device (hereinafter, referred to as a mobile pointing device) mounted directly on a mobile phone body is used. In the case of the mobile pointing device, the pointer (eg, a finger) may be moved on the surface of the mobile pointing device to implement the movement of the pointer according to the displacement value of the subject. In conclusion, the mobile pointing device moves the pointer according to the relative movement of the subject.

한편, 신호 입력부(123)는 로딩부(100)에 의해 인풋 디바이스(200)가 로딩되면, 중합체 물질(22)을 인풋 디바이스(200)에 직접 접촉시키지 않고 300μm 이내에서 근접시킨 상태에서 인풋 디바이스(200)로부터 전기적인 신호가 출력되도록 하는 것이 바람직하다. 물론, 중합체 물질(22)을 인풋 디바이스(200)에 직접 접촉시켜 검사가 수행되도록 해도 무방하다. 하지만, 많은 수의 인풋 디바이스(200)를 검사하기 위해 중합체 물질(22)을 많은 수의 인풋 디바이스(200)에 연속적으로 접촉시키다 보면, 마찰에 의해 중합체 물질의 내구성이 급격히 저하되는 문제점이 발생한다. 따라서, 중합체 물질(22)을 인풋 디바이스에 직접 접촉시키지 않고, 인풋 디바이스의 인식 범위(즉, 중합체 물질 근접에 의해 전기적인 신호를 출력할 수 있는 범위) 내에서 일정거리 이격시켜 검사를 수행하는 것이 바람직하다.Meanwhile, when the input device 200 is loaded by the loading unit 100, the signal input unit 123 does not directly contact the polymer material 22 with the input device 200 but within 300 μm. It is desirable to have the electrical signal output from the 200). Of course, the polymer material 22 may be in direct contact with the input device 200 so that the inspection can be performed. However, when the polymer material 22 is continuously contacted with a large number of the input device 200 to inspect a large number of the input device 200, a problem arises in that the durability of the polymer material is sharply degraded by friction. . Therefore, it is preferable to perform the inspection by keeping the polymer material 22 at a predetermined distance without being in direct contact with the input device, but within a recognition range of the input device (that is, an electric signal can be output by the proximity of the polymer material). desirable.
제어부(50)는 로딩부(100), 신호 입력부(123), 및 분리부(60)의 동작을 제어하여 인풋 디바이스(200)의 동작성능 검사가 순차적으로 수행될 수 있도록 처리하고, 인풋 디바이스(200)로부터 수신한 전기적인 신호를 인풋 디바이스(200)의 동작성능을 검사하여 동작성능 검사에 따른 결과 데이터를 출력한다.The controller 50 controls the operation of the loading unit 100, the signal input unit 123, and the separation unit 60 so that the operation performance inspection of the input device 200 may be sequentially performed, and the input device ( The operation signal of the input device 200 is inspected using the electrical signal received from the device 200, and the result data according to the operation performance test is output.
보다 상세하게는, 제어부(50)는 검사부(52), 표시부(54), 및 특성변수 설정부(56)를 구비한다.More specifically, the control unit 50 includes an inspection unit 52, a display unit 54, and a characteristic variable setting unit 56.

특성변수 설정부(56)는 중합체 물질(22)에 대한 물리적 특성값, 화학적 특성값, 및 전기적 특성값 등을 포함하는 특성 변수들을 사용자로부터 입력받아 검사부(52)에 전달한다. 여기서, 물리적 특성값은 중합체 물질의 마찰계수, 탄성계수, 내구성, 및 표면패턴들을 포함할 수 있고, 화학적 특성값은 중합체 물질의 구성 성분비, 입도 구성비들을 포함할 수 있으며, 전기적 특성값은 IR 파장대의 산란계수 및 흡수계수, 비유전율, 도전율들을 포함할 수 있다. 즉, 검사부(52)는 특성변수 설정부(56)를 통해 입력된 상기한 특성 변수들을 고려하여 해당 인풋 디바이스(200)의 동작성능을 검사한다. 인풋 디바이스(예, 포인팅 장치)의 동작성능은 중합체 물질의 물리적 특성값, 화학적 특성값, 및 전기적 특성값 등에 따라 달라질 수 있다. 이러한 특성 변수를 고려하지 않고 검사를 수행할 경우, 중합체 물질의 특성값에 따라 검사 결과가 달라질 수 있으며, 이는 검사 결과의 신뢰성을 저해시키는 요인이 된다. 따라서, 본 발명에서는 중합체 물질의 특성변수를 고려하여 인풋 디바이스의 동작성능을 검사하고, 이를 통해 보다 신뢰성 있는 검사결과를 획득할 수 있도록 하였다.The characteristic variable setting unit 56 receives characteristic variables including a physical characteristic value, a chemical characteristic value, an electrical characteristic value, and the like for the polymer material 22 from the user and transmits them to the inspection unit 52. Herein, the physical property value may include a friction coefficient, elastic modulus, durability, and surface patterns of the polymer material, and the chemical property value may include a constituent ratio and a particle size ratio of the polymer material, and the electrical characteristic value may include an IR wavelength band. It may include the scattering coefficient and absorption coefficient, relative dielectric constant, conductivity of. That is, the inspection unit 52 examines the operation performance of the corresponding input device 200 in consideration of the characteristic variables input through the characteristic variable setting unit 56. The operating performance of the input device (eg, pointing device) may vary depending on the physical, chemical, and electrical properties of the polymeric material. When the test is performed without considering these characteristic variables, the test result may be changed according to the characteristic value of the polymer material, which is a factor that hinders the reliability of the test result. Therefore, in the present invention, the operational performance of the input device is examined in consideration of the characteristic variables of the polymer material, and thus, more reliable test results can be obtained.

로딩부(100)는 유수분 발생부(12), 유수분 제거부(14), 연결부(미도시)를 구비한다(도 2 참조).The loading unit 100 includes a water oil generating unit 12, a water oil removing unit 14, and a connecting unit (not shown) (see FIG. 2).
유수분 분사부(12)는 신호 입력부(123)에 의해 중합체 물질이 인풋 디바이스(200)에 근접 또는 접촉되기 전에 인풋 디바이스(200)의 표면에 유분 및 수분을 분사한다. 이때, 유수분 분사부(12)에서 분사되는 액체는 사람의 땀과 유사한 성분으로 구성되는 것이 바람직하다. 인풋 디바이스(200)가 전술한 포인팅 장치인 경우, 포인팅 장치는 실사용 환경에서 인체로부터 분비되는 액체(예, 땀)에 영향을 받는 환경에 노출되게 된다. 이에, 본 발명에서는 전술한 포인팅 장치의 동작성능 검사시 실사용 환경과 최대한 유사한 환경에서 동작성능 검사가 수행될 수 있게 해줌으로써, 보다 신뢰성 있는 검사결과를 획득할 수 있도록 한다.The oil jet 12 sprays oil and water onto the surface of the input device 200 before the polymer material is brought into or close to the input device 200 by the signal input 123. At this time, the liquid injected from the oil and water injection unit 12 is preferably composed of a component similar to human sweat. When the input device 200 is the above-described pointing device, the pointing device is exposed to an environment affected by liquid (eg, sweat) secreted from the human body in a practical use environment. Thus, in the present invention, the operation performance test can be performed in the environment as close as possible to the actual use environment when the operation performance test of the above-mentioned pointing device, so that a more reliable test result can be obtained.

한편, 상기한 설명 및 도 2에서는 유수분 분사부(12)가 로딩부(100)에 구비되어 있는 것으로 설명하였지만, 유수분 분사부(12)는 신호 입력부(123)에 구비되어 있어도 무방하다. 즉, 중합체 물질이 인풋 디바이스(200)에 근접 또는 접촉되기 전에 신호 입력부(123) 내부에서 인풋 디바이스(200)의 표면에 유분 및 수분을 분사해줌으로써 전술한 바와 동일 또는 유사한 효과를 달성할 수 있다.Meanwhile, in the above description and FIG. 2, the oil-water injection unit 12 is described as being provided in the loading unit 100, but the oil-water injection unit 12 may be provided in the signal input unit 123. That is, the same or similar effects as described above may be achieved by spraying oil and water on the surface of the input device 200 inside the signal input unit 123 before the polymer material is in close proximity to or in contact with the input device 200. .
이하에서는 본 발명에 따른 인풋 디바이스 테스트 장치에 적용될 수 있는 포인팅 장치에 대해서 보다 상세하게 설명하기로 한다.Hereinafter, a pointing device that can be applied to the input device test device according to the present invention will be described in detail.
먼저, 적외선(IR) 또는 레이저(Laser)를 광원으로 이용하는 포인팅 장치는 광원부(미도시), 광원부에 의해 조명되며, 피사체(예, 손가락, 중합체 물질)에 근접 또는 접촉되는 커버 하우징(미도시), 피사체에 의해 반사된 광을 검출하는 수광부(미도시), 및 피사체에 의해 반사된 광을 상기 수광부로 안내하는 광가이드부(미도시)를 구비할 수 있다. First, a pointing device using an infrared ray (IR) or a laser (Laser) as a light source is a cover housing (not shown) that is illuminated by a light source unit (not shown), the light source unit, or in proximity to or in contact with a subject (eg, a finger, a polymer material). , A light receiving unit (not shown) for detecting the light reflected by the subject, and a light guide unit (not shown) for guiding the light reflected by the subject to the light receiving unit.
광원부는 요구되는 광의 조도량에 대응하는 적외선 LED(Light-Emitting Diode) 또는 LD(Laser Diode)를 통해 구현될 수 있다. LED와 LD는 광을 조사하는 출력량에서 차이점이 있는데, 비교적 적은 광량으로 출력이 요구될 경우 LED를 사용하고, 반대로 비교적 많은 광량으로 출력이 요구될 경우 LD를 사용한다. 따라서, 광원부에 사용되는 LED와 LD는 포인팅 장치의 설계사양에 따라 선택적으로 사용될 수 있다The light source unit may be implemented through an infrared light-emitting diode (LED) or a laser diode (LD) corresponding to the amount of illuminance of the required light. LED and LD have a difference in the output amount of light irradiation, LED is used when output is required with a relatively small amount of light, and LD is used when output is required with a relatively large amount of light. Therefore, the LED and the LD used in the light source unit may be selectively used according to the design specifications of the pointing device.
커버 하우징의 외측면(상측면)에는 전자기기의 조작을 위하여 피사체가 접촉 또는 근접되는 조작면이 형성되며, 수광부는 입력되는 광신호의 처리를 위하여 PCB에 구비된다. 이에 따라, 조작면에 피사체를 접촉 또는 근접시켜 움직이면, 피사체의 움직임에 따라 수광부에 입력되는 광신호가 변화된다.An outer surface (upper surface) of the cover housing is provided with an operation surface to which the subject contacts or approaches to operate the electronic device, and the light receiving unit is provided on the PCB for processing the input optical signal. Accordingly, when the subject is brought into contact with or close to the operation surface, the optical signal input to the light receiving unit changes according to the movement of the subject.
커버 하우징은 광원에서 출사되는 광이 투과되기 위해 광학 플라스틱으로 제조될 수 있다. 예를 들어, 광원부에서 출사되는 광이 IR(적외선)일 경우 적외선만이 투과되도록 광학 플라스틱을 구성하거나 투명부재(예, 투명 플라스틱)에 IR 레진 등을 코팅하여 구성할 수 있다.The cover housing may be made of optical plastic to transmit light emitted from the light source. For example, when the light emitted from the light source unit is IR (infrared rays), the optical plastic may be configured to transmit only infrared rays, or the IR resin may be coated on a transparent member (eg, transparent plastic).
수광부는 변화된 광신호를 이용하여 피사체의 움직임에 따른 변위값을 산출하고, 이에 대응하는 전기적인 신호를 출력한다. 보다 상세하게 설명하면, 커버 하우징의 조작면에 피사체가 접촉되지 않은 상태에서는 광원부에서 출사된 광이 커버 하우징을 투과하면서 커버 하우징의 외부로 방출된다. 반면, 커버 하우징의 조작면에 손가락 등의 피사체가 근접 또는 접촉되면, 광원부에서 출사된 광이 피사체에 부딪혀 반사된 후 광가이드부를 거쳐 수광부에서 입사되고, 이에 따라 피사체의 이미지가 광신호로 촬상된다.The light receiver calculates a displacement value according to the movement of the subject using the changed optical signal, and outputs an electrical signal corresponding thereto. In more detail, the light emitted from the light source unit is emitted to the outside of the cover housing while the subject is not in contact with the operation surface of the cover housing. On the other hand, when a subject such as a finger approaches or comes into contact with the operation surface of the cover housing, the light emitted from the light source unit hits the object and is reflected, and then enters from the light receiving unit through the light guide unit, thereby photographing the image of the subject as an optical signal. .
광가이드부는 피사체에서 반사되는 광원을 통과시켜서 수광부의 광 검출역역으로 광을 가이드한다. 이때, 광가이드부는 조리개 기능, 집광 기능, 광 필터링 등을 수행할 수 있다.The light guide unit guides the light to the light detection region of the light receiving unit by passing the light source reflected from the subject. In this case, the light guide unit may perform an aperture function, a light collecting function, a light filtering, and the like.
한편, 광원부가 LED(Light-Emitting Diode)를 통해 구현되는 경우에는, 광가이드부는 피사체에 의해 반사된 입사광을 미리 설정된 각도대로 굴절시켜 진행시키기 위한 프리즘(또는 반사체)과 입사된 광을 집광하기 위한 집광렌즈 등으로 구성되는 광학계를 구비할 수 있다. 그리고, 광원부가 LD(Laser Diode)를 통해 구현되는 경우에는, 광가이드부는 LD에서 출사되는 출사광을 커버 하우징에 조명하기 위한 조명홀과 피사체에 의해 반사된 입사광을 수광부로 가이드하기 위한 입사홀을 구비할 수 있다. 여기서, 광학계의 구성은 상기한 구성에 한정되는 것은 아니며, 포인팅 장치의 설계사양에 따라 선택적으로 변경될 수 있다.On the other hand, when the light source unit is implemented through an LED (Light-Emitting Diode), the light guide unit for condensing the incident light and the prism (or reflector) for advancing by refracting the incident light reflected by the subject at a predetermined angle An optical system composed of a condenser lens or the like can be provided. When the light source unit is implemented through a laser diode (LD), the light guide unit includes an illumination hole for illuminating the light emitted from the LD to the cover housing and an entrance hole for guiding the incident light reflected by the subject to the light receiving unit. It can be provided. Here, the configuration of the optical system is not limited to the above configuration, and may be selectively changed according to the design specifications of the pointing device.
다음으로, 전기장(electric field)을 이용하는 포인팅 장치는 피사체(예, 손가락, 중합체 물질)의 접촉면에 전기장을 형성하는 송신부(미도시), 피사체의 접촉에 의해 변화된 전기장을 수신하고, 수신한 전기장으로부터 패턴신호를 검출하는 검출부(미도시), 및 패턴신호로부터 피사체의 움직임에 따라 변하는 패턴변위를 산출하는 산출부(미도시)를 구비할 수 있다.Next, a pointing device using an electric field includes a transmitter (not shown) that forms an electric field on a contact surface of a subject (for example, a finger and a polymer material), and receives an electric field changed by contact of the subject, and receives the received electric field from the received electric field. A detection unit (not shown) for detecting a pattern signal and a calculation unit (not shown) for calculating a pattern displacement that changes according to the movement of the subject from the pattern signal may be provided.
송신부는 접촉면을 포함하는 영역에 전기장을 형성한다. 이때, 전기장은 금속막의 플레이트를 통해 형성할 수 있다.The transmitter forms an electric field in the area including the contact surface. In this case, the electric field may be formed through the plate of the metal film.
검출부는 전기장 영역에 접촉된 피사체의 변화된 전기장을 수신하고, 수신한 전기장으로부터 패턴신호를 출력한다.The detection unit receives the changed electric field of the subject in contact with the electric field area and outputs a pattern signal from the received electric field.
산출부는 검출부에서 출력된 패턴신호로부터 물체의 이동에 따라 변하는 패턴변위를 산출한다. 예를 들어, 피사체가 사용자의 손가락인 경우, 손가락 표면에 형성된 골과 산의 패턴을 스캔하여 지문 이미지를 획득한다.The calculator calculates a pattern displacement that changes according to the movement of the object from the pattern signal output from the detector. For example, when the subject is a user's finger, a fingerprint image is obtained by scanning a pattern of valleys and mountains formed on the surface of the finger.
도 3은 본 발명에 따른 동작성능 검사방법을 설명하기 위한 흐름도이다.3 is a flowchart illustrating a method for checking operation performance according to the present invention.
본 발명에 따른 동작성능 검사방법은, 크게, 중합체 물질의 근접 또는 접촉에 대응하는 전기적인 신호를 출력하는 인풋 디바이스가 로딩되면, 중합체 물질을 상기 인풋 디바이스에 근접 또는 접촉시켜 상기 인풋 디바이스로부터 전기적인 신호가 출력되도록 하는 단계; 상기 중합체 물질의 근접 또는 접촉에 대응하여 상기 인풋 디바이스로부터 출력되는 전기적인 신호를 수신하는 단계; 수신한 전기적인 신호를 이용하여 상기 인풋 디바이스의 동작성능을 검사하는 단계; 및 동작성능 검사에 따른 결과 데이터를 출력하는 단계를 포함한다.The operation performance inspection method according to the present invention is largely provided that when an input device that outputs an electrical signal corresponding to the proximity or contact of a polymer material is loaded, the polymer material is brought into proximity or contact with the input device to be electrically connected from the input device. Causing a signal to be output; Receiving an electrical signal output from the input device in response to proximity or contact of the polymeric material; Checking an operating performance of the input device using the received electrical signal; And outputting result data according to the operation performance test.
도 3을 참조하여 보다 상세하게 설명하면, 먼저, 로딩부는 검사 대상인 인풋 디바이스를 로딩한다(S100). 여기서, 인풋 디바이스는 중합체 물질의 근접 또는 접촉에 대응하는 전기적인 신호를 출력하는 인풋 디바이스가 로딩되면, 중합체 물질의 근접 움직임 또는 접촉 움직임에 따른 변위에 대응하는 전기적인 신호를 출력하는 포인팅 장치가 될 수 있으며, 적외선, 레이저, 전기장 중 하나 이상을 이용하여 피사체(예, 손가락, 생체모방조직)의 근접 움직임 또는 접촉 움직임에 따른 변위에 대응하는 전기적인 신호를 출력하는 장치가 될 수 있다. 그리고, S100 단계에서의 '로딩'은 인풋 디바이스를 정해진 검사위치로 위치시키는 단계와, 인풋 디바이스의 구동에 필요한 전원을 인풋 디바이스에 공급하고, 인풋 디바이스를 동작성능을 검사하는 검사부와 인풋 디바이스를 전기적으로 연결시켜 본 발명에 따른 인풋 디바이스 테스트 장치가 인풋 디바이스의 동작성능을 검사를 수행할 수 있도록 하는 단계를 포함한다.Referring to Figure 3 in more detail, first, the loading unit loads the input device to be inspected (S100). Here, the input device may be a pointing device that outputs an electrical signal corresponding to a displacement due to proximity movement or contact movement of the polymer material when the input device is loaded, which outputs an electrical signal corresponding to the proximity or contact of the polymeric material. The electronic device may be an apparatus that outputs an electrical signal corresponding to a displacement caused by proximity movement or contact movement of a subject (eg, finger, biomimetic tissue) using at least one of an infrared ray, a laser, and an electric field. In operation S100, the “loading” includes placing the input device at a predetermined test position, supplying power for driving the input device to the input device, and electrically connecting the test device and the input device to check the operation performance of the input device. Connecting to the input device test apparatus according to the present invention so that the operation performance of the input device can be inspected.
S100 단계를 통해 인풋 디바이스가 로딩되면, 신호 입력부는 중합체 물질을 인풋 디바이스에 근접 또는 접촉시켜 인풋 디바이스로부터 전기적인 신호가 출력되게 한다(S110). 근접시는, 중합체 물질을 인풋 디바이스에 직접 접촉시키지 않고 300μm 이내에서 근접시킨 상태에서 인풋 디바이스로부터 전기적인 신호가 출력되도록 하는 것이 바람직하다. 물론, 중합체 물질을 인풋 디바이스에 직접 접촉시켜 검사가 수행되도록 해도 무방하다. 하지만, 많은 수의 인풋 디바이스를 검사하기 위해 생체모방조직을 많은 수의 인풋 디바이스에 연속적으로 접촉시키다 보면, 마찰에 의해 중합체 물질의 내구성이 급격히 저하되는 문제점이 발생한다. 따라서, 중합체 물질을 인풋 디바이스에 직접 접촉시키지 않고, 인풋 디바이스의 인식 범위(즉, 중합체 물질의 근접에 의해 전기적인 신호를 출력할 수 있는 범위) 내에서 일정거리 이격시켜 검사를 수행하는 것이 바람직하다.When the input device is loaded through the step S100, the signal input unit contacts or contacts the polymer material with the input device to output an electrical signal from the input device (S110). In proximity, it is desirable for the electrical signal to be output from the input device while the polymer material is in proximity within 300 μm without directly contacting the input device. Of course, the polymer material may be in direct contact with the input device so that the inspection can be performed. However, continuous contact of the biomimetic tissue to a large number of input devices to inspect a large number of input devices causes a problem that the durability of the polymer material is drastically degraded by friction. Thus, it is desirable to perform the inspection at some distance apart within the recognition range of the input device (i.e., the range in which the electrical signal can be output by proximity of the polymeric material) without directly contacting the polymeric material with the input device. .
S110 단계를 통해 인풋 디바이스로부터 근접 또는 접촉에 대응하는 전기적인 신호가 출력되면, 검사부는 인풋 디바이스로부터 출력되는 전기적인 신호를 수신한다(S120).When the electrical signal corresponding to the proximity or contact is output from the input device through the step S110, the inspection unit receives the electrical signal output from the input device (S120).
S120 단계를 통해 전기적인 신호를 수신한 검사부는 인풋 디바이스로부터 수신한 신호를 이용하여 인풋 디바이스의 동작성능을 검사한다(S130). 이때, 검사부는 사전에 사용자로부터 입력받은 중합체 물질에 대한 물리적 특성값, 화학적 특성값, 및 전기적 특성값 등을 포함하는 특성 변수를 고려하여 해당 인풋 디바이스의 동작성능을 검사한다.The inspection unit that receives the electrical signal through the step S120 checks the operation performance of the input device using the signal received from the input device (S130). In this case, the inspection unit examines the operation performance of the corresponding input device in consideration of characteristic variables including physical characteristic values, chemical characteristic values, and electrical characteristic values for the polymer material previously input from the user.
다음으로, 검사부는 동작성능 검사에 따른 결과 데이터를 출력한다(S140). 동작성능 검사에 따른 결과 데이터에는 해당 인풋 디바이스의 불량 여부, 현재까지 검사된 인풋 디바이스의 개수, 불량율/개수, 양품율/개수, 진행상황, 중합체 물질의 마모 상태(내구성), 생체모방조직의 교체 예정시기 등에 대한 데이터가 포함될 수 있다.Next, the inspection unit outputs the result data according to the operation performance test (S140).
