Description

엔드레스 블렉보드 제작{How to make endless black board}How to make endless black board}

본 발명은 회전식 흑판에 관한 것이다. 현재 각 사용처에서 가장 많이 쓰이고 있는 흑판은 재래식 고정 흑판이다. 이 고정식 흑판은 가장 오래된 것으로서 다소의 불편한 점이 있었는데 그것은 흑판에 판서를 다하고 나면 일일이 손 지우개로 지워야 한다는 점이다. 이때 문제는 그것이 깨끗이 지워지지 않는다는 점이다. 만족할 만하게 지워질려면 상당한 공을 들여야 했었다. 그러나 본 발명품은 회전식이므로 흑판에 부착된 자동화 지우개에 의하여 아주 깨끗하게 순식간에 지워질 수가 있다는 것이다. 아울러 재래식 고정 흑판은 판서할 때 그 판서하는 사람이 높은 곳은 발꿈치를 들어서 낮은 곳은 허리를 굽혀서 사람이 손 높이를 맞추어 판서를 해야 했었는데 장시간 사용하는 사람의 경우 큰 고역이 아닐 수 없었다. 그러나 본 제품은 회전식이므로 높낮이를 간단하게 조작할 수 있어서 종래의 불편을 해소할 수 있는 것이 큰 특징이다. 그리고 이동식이므로 광선의 방향에 적응시킬 수 있어서 눈부심등을 피해 잘 보일 수 있는 이점도 있다.The present invention relates to a rotating blackboard. The most commonly used blackboards in each application are conventional fixed blackboards. This stationary blackboard was the oldest and had some inconveniences, which had to be erased with a hand eraser after the writing was done. The problem is that it is not cleaned up. To be satisfactorily erased, a great deal of effort was required. However, since the present invention is a rotary type, it can be erased very cleanly by an automated eraser attached to a blackboard. In addition, when writing conventional fixed blackboards, the writers had to raise the heels at the high places and bend their backs at the low places. However, since this product is a rotary type, it is possible to easily operate the height, which is a big feature that can solve the conventional inconvenience. And because it is movable, it can be adapted to the direction of the light beam, there is an advantage that can be seen well avoiding glare.
