Abstract: 본 발명은 우리가 흔히 쓰고 있는 메모(특히 부재중 전화 메모)용으로 사용하고 있는 Post-it등을 포함한 메모지나 종이 쪽지 등의 불편함 및 괜한 종이 낭비를 줄일 수 있는 메모판 세트로서 크게 메모판과 필기 할 수 있는 전용펜 그리고 전용 지우개로 구성 된다. 현재 우리 일상에 특히 사무실등에서 부재중인 사람에게 전화가 걸려오면 메모지(쪽지 묶음)이나 Post-it등에 전화내용을 적어 수신자 책상에 올려놓아 수신자가 돌아오면 전화가 왔었음을 알린다. 이때 사용된 쪽지나 Post-it등은 바로 휴지통에 버려진다. 이것도 낭비일 수 있다. 특히 Post-it은 꽤 비싼 것이다. 따라서 본인은 이를 개선하고자 버리지 않고 수신 확인 후 지우고 또 쓸 수 있는, 반 영구적으로 사용할 수 있는 메모판 세트를 고안하였다. 
     본 고안 제품에 사용되는 메모판은 메모지만한 적당한 크기의 판의 양쪽 표면을 화이트보드와 같이 표면처리 하여 사용한다. 따라서는 아크릴과 같은 플라스틱을 사용할 수 도 있다. 전용펜은 보드마카의 형태 및 크기를 사인펜과 같이 만들어 쉽게 필기할 수 있는 보드마카를 만드는 것이다. 지우개도 화이트 보드에서 쓰이는 지우개의 크기를 줄이는 것으로 재질과 방법은 같은 것이다. 
     첨부 도면을 참조하여 구성을 설명하면 
     [도]에 나타낸 바와 같이 기본 구성품으로 1.기록판, 2.전용펜,3. 초소형 전용 지우개,4.고정판,5.고정링으로 구성되며 다양한 용도로 응용 적용할 수 있다.1.기록판은 화이트보드와 같은 재질로서 전용펜으로 쓰고 얼마든지 지우고 또 쓸 수있으며,2.전용펜과 3.초소형 전용 지우개는 기록판에 쓰고 지우기 위해 반드시 옆에 위치 되어야 하는 것이다. 메모 내용이 추가될 경우를 대비하여 추가 구성품[도]등을 사용하여 묶음형태로 사용할 수 있다. 
     본 발명(고안)은 간단한 메모지 형태를 영구적으로 사용하도록 하여 장기적으로 종이 낭비를 크게 줄일 수 있으며, 책상의 일정한 장소에 있기 때문에 메모지 찾는다고 허둥대지 않아도 되며, 메모지 전달은 책상에서 잃어버리기 쉬워 수신자에게 전달이 않될 경우도 있지만 이 발명품은 수신자에게 확실하게 전달 할 수 있다는 것이다. 
     또한 사업측면에서 응용한다면 본 제품에 시계, 계산기등을 부착하여 상품을 고급화 할 수 있으며 광고등을 표시하여 선물이나 광고용으로 활용이 가능함
