본 고안은 다목적 물 그린 사이버칠판에 관한 것으로서, 보다 구체적으로는 좌표를 인식할 수 있는 광초음파 수신기를 그린색을 띄는 마카펜타입 물펜 전용 그린 칠판에 부착하여 칠판 내에서 전자펜을 이용하여 마우스 포인트 이동 및 인터넷 검색이 가능하도록 함으로 해서 환경오염이 전혀 없는 마카펜타입 물펜과 전자펜을 동시에 사용할 수 있도록 한 사이버 보드를 제공코자 것이다.The present invention relates to a multi-purpose water green cyber blackboard, and more specifically, attaches an optical ultrasonic receiver capable of recognizing coordinates to a green blackboard dedicated to a green marker marker pen that has a green color to move a mouse point using an electronic pen within the blackboard. And to provide a cyber board that can be used at the same time by using the Internet pen can be used at the same time the macapen type water pen and the electronic pen without any environmental pollution.

현재 학교 등에서 널리 사용되고 있는 대부분의 강의방식은 강의자가 분필이나 화이트보드 마카펜으로 판서를 하면서 강의를 진행하고 있으며, 이러한 강의방식은 판서한 내용을 지우는데 있어 분필의 분진가루, 칠판면의 얼룩, 마카펜 찌꺼기가 남고 특히, 분필가루는 강의자와 수강자의 건강에 나쁜 영향을 미칠 수 있다.Most of the lectures that are widely used in schools, etc. are taught by the lecturer writing with chalk or whiteboard markers, and these lecture methods are used to erase the written contents such as dust of chalk, smudges on the board, and markers. Leftovers remain, especially chalk powder, which can adversely affect the health of lecturers and students.

또한 기존학교의 컴퓨터실이나 특별실, 일반 강의실 등에 프로젝트를 이용하여 전자펜으로 간편하게 판서를 하면서 강의를 하는 전자칠판이 많이 제안된 바 있다.In addition, a number of electronic blackboards have been proposed for lectures by simply writing with an electronic pen using a project in a computer room, a special room, or a general lecture room of an existing school.

이러한 종래의 전자칠판은 전자펜을 이용하여 판서도 가능하며 시중에 나와 있는 마케펜 등으로도 판서가 가능하다. 그러나 전자펜이 아닌 마카펜으로 판서를 할 경우 보조칠판을 사용하여 판서해야 하고, 많은 양의 판서 시에는 크기가 너무 작아 2개의 보조칠판을 붙여서 쓰는 번거로움이 생겼다.Such a conventional electronic blackboard may be written using an electronic pen, or may be written with a marketed pen or the like. However, when writing with a marker instead of an electronic pen, it is necessary to write with a sub-blackboard, and when writing a large amount of paper, the size is too small to create two sub-blackboards.

이러한 문제점을 보완하여 크기가 큰 중앙 전자식칠판에 판서가 가능하도록 한 제품도 제안 되었지만 판서를 하고 난 뒤 지울 때 찌꺼기가 남고, 일정기간 쓰고 나면 전자식 칠판부에 얼룩이 생겨는 문제점도 생겼다.This product was also proposed to make the writing possible on the large central electronic board, but after the writing, there was a problem of residue left after writing, and after a certain period of time, there was a problem that the electronic blackboard was stained.

이에 본 고안자는 상기와 같은 종래의 분필이나 마카펜을 사용하는 칠판(화이트보드)나 전자칠판 등이 갖는 제반 문제점을 일소함에 고안의 기술적 과제를 두고 본 고안을 안출한 것으로서,In this regard, the present inventors have devised the present invention with the technical problem of the present invention in eliminating all the problems that the above-described conventional chalk or a marker pen uses, such as a white board or an electronic blackboard,

상기 기술적 과제를 해결할 수단으로 본 고안에서는 하나의 프레임에 알림판, 메인칠판, 보조칠판을 구성하여 공간 활용을 극대화하고, 메인칠판과 보조칠판은 그린색으로 구성하여 스크린 기능을 가지면서도 마카펜타입 물펜을 사용하게 함으로 해서 자유로운 판서를 할 수 있고 지우개에 찌꺼기가 남지 않으면서도 분진이 없도록 하였으며, 광초음파 수신기를 적용하여 전자펜을 이용. 마우스 포인트 이동 및 인터넷 검색이 가능하도록 한 것이다.In order to solve the above technical problem, the present invention maximizes space utilization by configuring a notice board, a main blackboard, and a subsidiary blackboard in one frame, and the main blackboard and the sub blackboard are configured in green color, and have a screen function and a marker pen type water pen. By using it, you can write freely, and there is no dust without leaving residue on the eraser, and it uses an electronic pen by applying an ultrasonic receiver. Mouse point movement and internet search are possible.

도 1은 본 고안이 적용된 사이버 칠판의 바람직한 일 실시예를 보인 사시도를 도시한 것이고, 도 2는 본 고안의 정면도, 도 3은 본 고안의 평단면도, 도 4는 본 고안의 측단면도를 도시한 것으로서, 이하에서 본 고안의 구성을 설명한다.1 is a perspective view showing a preferred embodiment of the cyber blackboard applied to the present invention, Figure 2 is a front view of the present invention, Figure 3 is a plan sectional view of the present invention, Figure 4 is a side cross-sectional view of the present invention. As one thing, the structure of this invention is demonstrated below.

Two sub-blackboards 6 and 6 'with the door car 6a running downward to slide along the rail 2a fixed to (2) are installed to be covered behind the bulletin boards 4 and 4'. .

상기 보조칠판(6)(6')의 크기는 메인칠판(5)의 1/2 정도이며, 메인칠판(5)과 보조칠판(6)(6')은 눈의 피로감을 없애주며 빛의 반사가 없는 금속판 재질의 그린색으로 구성하여 스크린 기능을 가질 수 있도록 하며, 마카펜타입 물펜(7)을 전용으로 사용할 수 있게 구성한다.The auxiliary blackboards 6 and 6 'are about 1/2 of the size of the main blackboard 5, and the main blackboard 5 and the auxiliary blackboards 6 and 6' eliminate eye fatigue and reflect light. It is configured to have a screen function by the green color of the metal plate material is not available, it is configured to be used exclusively the marker pen type pen (7).

상기 메인칠판(5)의 전방인 게시판(4)에는 광초음파 수신기(8)를 설치하여 전자펜(9)을 이용하여 마우스 포인트 이동 및 인터넷 검색이 가능하도록 한다.The bulletin board 4 in front of the main blackboard 5 is provided with an optical ultrasonic receiver 8 to enable the mouse point movement and internet search using the electronic pen 9.

상기 프레임(2) 하측으로는 물펜 수납통(10) 및 지우개(11)가 수납되는 지우개수납통(12)과 물통(13)이 설치되어 있으며, 사용하는 마카펜타입 물펜(7)은 판서된 상태에서 물과 접하면 소색(消色)되며 찌꺼기 없이 지워지는 친환경적인 것을 적용한다.Below the frame 2, the water pen holder 10 and the eraser container 12 and the water container 13, in which the eraser 11 is stored, are installed, and the marker pen type 7 to be used is in a written state. When it comes into contact with water, it is discolored (消 色) and eco-friendly that is erased without residue.

이상과 같이 구성되는 본 고안은 학교 등에서 칠판으로 사용할 수 있는 것으로서, 본 고안을 사용할 경우 메인칠판(5) 전방으로 게시판(4)(4') 후방에 내입되는 보조칠판(6)(6')이 설치되어 있으므로 판서 공간이 넓어 많은 량의 판서가 가능하며, 메인칠판(5)의 양측으로 설치되어 있는 게시판(4)(4')을 이용하여 다양한 게 시물을 게시할 수 있는바, 메인칠판(5)을 이용하여 판서 한 후 공간이 부족할 때에는 종래와 같이 판서내용을 지우지 않고 게시판(4)(4') 후방에 엄폐되어 있는 2개의 보조칠판(6)(6')을 슬라이드 이동시켜 판서가 가능하므로 공간 활용을 극대화 할 수 있다.The present invention configured as described above can be used as a blackboard in schools, etc., when using the present invention, the main blackboard (5) in front of the bulletin board (4) (4 ') to be embedded in the backboard (6) (6') Since the writing space is large, a large amount of writing is possible, and various posts can be posted using the bulletin boards 4 and 4 'installed on both sides of the main blackboard 5, and the main blackboard If there is not enough space after writing using (5), slide the two auxiliary blackboards (6) and (6 ') that are covered behind the bulletin board (4) and (4') without erasing the writing contents as in the prior art. It is possible to maximize space utilization.

그리고 본 고안은 메인칠판(5) 및 보조칠판(6)(6')이 눈의 피로감을 없애주며 빛의 반사가 없는 그린색으로 구성하여 스크린 기능을 가질 수 있도록 한 것이므로 별도로 스크린을 설치하는 등의 번거로움을 일소할 수 있는 것이며, 마카펜타입 물펜(7) 전용으로 구성되어 있는바, 판서 후 물 묻은 지우개(11)로 지울 경우 판서된 내용이 소색되므로 찌꺼기가 없어 분진 등으로 인해 발생하는 강의자와 수강자의 건강에 대한 문제점을 일소할 수 있는 것이다.And the present invention is to provide a screen function by the main blackboard (5) and the auxiliary blackboard (6) (6 ') to eliminate eye fatigue and to have a screen function by configuring a green color without the reflection of light, etc. It is possible to eliminate the hassle of, and it is composed only for the macapen type water pen (7). If the eraser is erased with water-stained eraser (11) after writing, the written contents disappear. You can eliminate problems with the health of students.
