본 고안은 슬라이드기능을 추가로 갖는 액정프로젝터에 관한 것이다.The present invention relates to a liquid crystal projector having a slide function.

일반적으로, 액정프로젝터는 광램프를 사용하여 액정판넬에 백색광을 비추면서, 액정판넬의 양단에 소정의 전압전원을 인가함으로써 피사체를 스크린에 확대투사한다. 또한, 슬라이드는 광램프를 사용하여 슬라이드필름에 백색광을 비춤으로써, 슬라이드필름의 피사체를 스크린에 확대하여 투사한다. 이와 같이, 액정프로젝터와 슬라이드는 동작방식에 있어서 유사한 부분을 갖고 있으나, 각각 고유의 기능만을 수행한다. 이에 따라, 각 기능을 구현하기 위해서는 별도의 장치를 사용하여야 한다.In general, a liquid crystal projector projects an object onto a screen by applying a predetermined voltage power to both ends of the liquid crystal panel while illuminating white light on the liquid crystal panel using an optical lamp. In addition, the slide uses a light lamp to project white light onto the screen by illuminating the white light on the slide film. As described above, the liquid crystal projector and the slide have similar parts in operation, but each performs only a unique function. Accordingly, a separate device must be used to implement each function.

따라서, 본 고안의 목적은 액정프로젝터와 슬라이드를 하나의 기기로 통합하여, 상기 두 기능을 하나의 시스템으로 구현하기 위한 슬라이드기능을 갖는 액정프로젝터을 제공함에 있다.Accordingly, an object of the present invention is to provide a liquid crystal projector having a slide function for implementing the two functions in one system by integrating the liquid crystal projector and the slide into a single device.

이와 같은 본 고안의 목적은 백색광램프와, 액정판넬과, 줌렌즈를 포함하는 액정프로젝터에 있어서, 상기 액정판넬과 줌렌즈 사이에서 액정판넬의 전면에 위치하고 슬라이드필름이 탈착가능하도록 형성된 슬라이드부재, 상기 슬라이드부재가 액정프로젝터 내로 삽입되도록 액정프로젝터 본체에 형성된 삽입부, 및 슬라이드기능 또는 액정프로젝터기능을 선택하기 위한 기능선택스위치에 의하여 달성된다.The object of the present invention is a liquid crystal projector including a white light lamp, a liquid crystal panel and a zoom lens, the slide member formed on the front of the liquid crystal panel between the liquid crystal panel and the zoom lens, the slide film is detachable, the slide member By means of an insertion portion formed in the liquid crystal projector body so that the liquid crystal projector is inserted into the liquid crystal projector, and a function selection switch for selecting a slide function or a liquid crystal projector function.

이하, 첨부한 도면을 참조하여 본 고안의 바람직한 실시예를 상술하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 의한 슬라이드기능을 갖는 액정프로젝터의 사시도로서, 액정프로젝터 본체(11)에 슬라이드부재(12)를 삽입할 수 있는 삽입부(13)를 구비한 것이다. 즉, 슬라이드기능을 수행하고자 하는 경우, 본체의 삽입부(13)에 슬라이드부재(12)를 삽입하고, 슬라이드부재(12)의 홈에 슬라이드필름(14)을 삽입하면 된다.1 is a perspective view of a liquid crystal projector having a slide function according to the present invention, and includes an insertion portion 13 into which the slide member 12 can be inserted into the liquid crystal projector main body 11. That is, when the slide function is to be performed, the slide member 12 may be inserted into the insertion part 13 of the main body, and the slide film 14 may be inserted into the groove of the slide member 12.

제2도는 제1도의 장치를 위하여 본 단면도이다. 제2도에서, 백색광램프(21), 필터(22), 집광렌즈(23), 액정판넬(24), 편광필터(25), 및 줌렌즈(26) 등은 액정프로젝터에 구비되는 기본적인 구성요소들이다. 백색광램프(21)에서 방출되는 백색광은 열차단용 필터(22)를 거쳐, 집광렌즈(23)에서 빛이 모아진 다음 액정판넬(24)로 비춰진다. 이때, 액정판넬(24)의 전후면에는 편광필터(25)가 각각 존재하고, 액정판넬(24)의 양측에 전압이 인가되면, 액정판넬의 피사체가 줌렌즈(26)에 의해 확대되어 스크린(27)에 투사된다. 이러한, 액정프로젝터에서 액정판넬(24)의 전면 또는 후면에 슬라이드필름(14)을 삽입할 수 있는 슬라이드부재(12)를 구비한다. 그러면, 백색광램프(21)에서 방출되는 백색광이 슬라이드필름(14)로 인가되어, 슬라이드필름의 피사체를 스크린에 확대 투사한다. 슬라이드기능이 수행될 때에는, 액정판넬(24)에 인가되는 전압전원을 차단함으로써, 백색광은 액정판넬(24)을 그대로 투과한다.2 is a cross sectional view for the apparatus of FIG. In FIG. 2, the white light lamp 21, the filter 22, the condenser lens 23, the liquid crystal panel 24, the polarization filter 25, and the zoom lens 26 are the basic components provided in the liquid crystal projector. . The white light emitted from the white light lamp 21 passes through the thermal barrier filter 22, collects light from the condenser lens 23, and then shines onto the liquid crystal panel 24. In this case, when the polarization filter 25 is present on each of the front and rear surfaces of the liquid crystal panel 24, and voltage is applied to both sides of the liquid crystal panel 24, the subject of the liquid crystal panel is enlarged by the zoom lens 26 to display the screen 27. Projected on). In the liquid crystal projector, there is provided a slide member 12 into which the slide film 14 can be inserted into the front or rear surface of the liquid crystal panel 24. Then, the white light emitted from the white light lamp 21 is applied to the slide film 14 to enlarge and project the subject of the slide film on the screen. When the slide function is performed, white light passes through the liquid crystal panel 24 as it is by cutting off the voltage power applied to the liquid crystal panel 24.

이와 같이, 본 고안은 슬라이드기능과 액정프로젝터기능을 선택적으로 수행하게 되므로, 두 기능을 선택하기 위한 기능을 선택하기 위한 기능선택스위치(도시되지 않음)를 별로로 구비한다. 즉, 슬라이드로서 동작하고자 하는 경우, 기능선택스위치를 슬라이드기능으로 선택하고 슬라이드부재(12)와 슬라이드필름(14)을 삽입한 후 동작을 수행한다. 또한, 액정프로젝터로서 동작하고자 하는 경우, 슬라이드부재(12)와 슬라이드필름(14)을 본체에 삽입하지 않고 기능선택스위치를 액정프로젝터기능으로 선택한 후 동작을 수행한다.As such, the present invention selectively performs the slide function and the liquid crystal projector function, and thus has a separate function selection switch (not shown) for selecting a function for selecting two functions. That is, when operating as a slide, the function selection switch is selected as the slide function and the slide member 12 and the slide film 14 are inserted and then performed. In addition, in the case where the liquid crystal projector is to be operated, the function selection switch is selected as the liquid crystal projector function without the slide member 12 and the slide film 14 inserted into the main body, and then the operation is performed.

상술한 바와 같이, 본 고안에 의한 슬라이드기능을 갖는 액정프로젝터는 하나의 시스템으로 슬라이드기능과 액정프로젝터기능을 수행할 수 있으므로, 사용이 편리하고 제품의 가격이 인하되는 효과가 있다.As described above, the liquid crystal projector having a slide function according to the present invention can perform the slide function and the liquid crystal projector function in one system, so that the use of the product is convenient and the price of the product is lowered.
