Abstract

본 고안은 칠판을 구비한 스탠드형 프로젝터 스크린에 관한 것이다. 스탠드형 프로젝터 스크린은 실내 및 실외의 바닥에 설치하고 프로젝터의 영상을 상영하는 시청용으로 사용하는 것이 일반적이다. 그런데 이와 같은 종래의 스탠드형 프로젝터 스크린은 프로젝터의 영상을 상영하는 기능이외 다른 기능은 기대할 수 없는 결점이 있었다. 이에 본 고안은 스탠드형 프로젝터 스크린의 스크린이 시트로 구성된 것에 착안하여, 스크린의 상단부에 합성수지(폴리프로필렌)코팅막이 도포된 시트로 칠판을 형성함으로서, 프로젝터의 영상을 상영한 후 영상물에 대한 브리핑을 위하여 별도의 칠판을 필요로 하지 아니하게 하는 칠판을 구비한 스탠드형 프로젝터 스크린을 제공하려 하는 것이다.The present invention relates to a stand-type projector screen with a blackboard. Stand-up projector screens are commonly used on indoor and outdoor floors and for viewing to view projector images. However, such a conventional stand-type projector screen has a drawback that cannot be expected other than the function of screening the projector image. Therefore, the present invention focuses on the screen of the stand type projector screen composed of sheets, and forms a blackboard with a sheet coated with a synthetic resin (polypropylene) coating on the upper part of the screen, so that the briefing of the image after screening the image of the projector is performed. In order to provide a stand-alone projector screen with a blackboard that does not require a separate blackboard for this purpose.

본 고안은 칠판을 구비한 스탠드형 프로젝터 스크린에 관한 것이다. 스탠드형 프로젝터 스크린은 실내 및 실외의 바닥에 설치하고 프로젝터의 영상을 상영하는 홍보 및 시청각 교육용으로 사용하는 것이 일반적이다.The present invention relates to a stand-type projector screen with a blackboard. Stand-alone projector screens are commonly used on indoor and outdoor floors and for promotional and audiovisual training, showing the projector's video.

그런데 이와 같은 종래의 스탠드형 프로젝터 스크린은 프로젝터의 영상을 상 영하는 기능이외 다른 기능은 기대할 수 없었고, 영상을 상영한 후 영상물에 대한 브리핑을 위하여 별도의 칠판을 사용해야 하는 불편한 문제점이 있었다.However, such a conventional stand-type projector screen could not be expected other functions than the function of screening the image of the projector, there was an inconvenience that you need to use a separate blackboard for briefing on the image after screening the image.

이에 본 고안은 스탠드형 프로젝터 스크린의 스크린이 시트로 구성된 것에 착안하여, 스크린의 상단부에 합성수지(폴리프로필렌)코팅막이 도포된 시트로 칠판을 형성함으로서, 프로젝터의 영상을 상영한 후 영상물에 대한 브리핑을 위하여 별도의 칠판을 필요로 하지 아니하게 하는 칠판을 구비한 스탠드형 프로젝터 스크린을 제공하려 하는 것이다. 이와 같은 본 고안을 첨부한 도면에 의하여 설명하면 다음과 같다.Therefore, the present invention focuses on the screen of the stand type projector screen composed of sheets, and forms a blackboard with a sheet coated with a synthetic resin (polypropylene) coating on the upper part of the screen, so that the briefing of the image after screening the image of the projector is performed. In order to provide a stand-alone projector screen with a blackboard that does not require a separate blackboard for this purpose. Referring to the accompanying drawings, the present invention as follows.

도 1은 본 고안에 따른 칠판을 구비한 스탠드형 프로젝터 스크린의 실시예를 도시한 개념도로서, 이에 도시된 바와 같이, 스크린본체(10)를 구성하는 몸체(20)의 내부에 감겨진 상태에서 상부로 신장되도록 설치하여 사용하는 스크린(30)의 상단부에 칠판(40)이 형성되어 있다.1 is a conceptual diagram showing an embodiment of a stand-type projector screen with a blackboard according to the present invention, as shown in the upper portion in the state wound around the body 20 constituting the screen body 10 Blackboard 40 is formed on the upper end of the screen 30 to be installed and used to extend.

상기와 같이 형성된 칠판(40)은 합성수지(폴리프로필렌)코팅막(50)을 표면에 도포한 시트(60)를 소재로 구성되어 있으며, 표면이 매끄러운 합성수지(폴리프로필렌)코팅막(50)으로 구성됨으로 인하여 수성펜 및 마카펜(라텍스계열 잉크 사용 펜)등으로 기재가 용이하며 기재된 내용을 지우개 등으로 손쉽게 지울 수 있는 것이다. 또한 칠판(40)의 뒷면이 시트(60)로 구성됨으로 인하여 연결된 스크린(30)을 따라 몸체(20)의 내부에 수납이 용이하고, 상부로의 신청이 용이한 것이다.The board 40 formed as described above is composed of a sheet 60 coated with a synthetic resin (polypropylene) coating film 50 on the surface, and is composed of a synthetic resin (polypropylene) coating film 50 having a smooth surface. Aqueous pens and maca pens (latex ink pens) can be used for easy writing, and the contents can be easily erased with an eraser. In addition, since the back of the blackboard 40 is composed of a sheet 60, it is easy to receive in the interior of the body 20 along the connected screen 30, it is easy to apply to the top.

이와 같이 구성된 본 고안은 필요에 따라, 스크린(30)을 신장시켜 몸체(20)의 상부로 노출되도록 설치함으로서 프로젝터의 영상을 상영할 수 있으며, 프로젝터의 영상을 상영한 후 스크린(30)부분을 몸체(20)의 내부에 수납시키고 칠판(40)부분만을 상부로 노출되도록 설치하여 브리핑 등의 홍보 및 교육을 위한 기재용으로 사용할 수 있는 것이다.The present invention configured as described above, by extending the screen 30 to be installed so as to be exposed to the upper portion of the body 20 can screen the image of the projector, after screening the image of the projector screen 30 The interior of the body 20 and installed so that only the blackboard 40 is exposed to the upper portion can be used as a substrate for publicity and education, such as briefing.

이와 같은 본 고안은 상술한 바와 같은 기술적 구성에 한정되지 아니하고 그 기술적 목적을 달성하기 위하여 상기의 구조와 균등한 다양한 임의의 구조로 실시될 수 있다.This invention is not limited to the above-described technical configuration and may be implemented in various arbitrary structures equivalent to the above structure in order to achieve the technical purpose.

상기와 같이 구성된 본 고안의 칠판을 구비한 스탠드형 프로젝터 스크린은 프로젝터의 영상을 재생할 수 있으며, 스크린을 사용 한 후 곧바로 브리핑을 위한 칠판으로 사용할 수 있는 효과를 기대할 수 있다.Stand-type projector screen with a blackboard of the present invention configured as described above can reproduce the image of the projector, can be expected to be used as a blackboard for briefing immediately after using the screen.
