Abstract: 본 발명은 탁구연습기구에 관한 것으로서, 
탁구 연습할 때에 타격 판 중심에 공을 일정하게 맞추면 탁구대 상판의 일정한 위치에 떨어지게 되어 연속적으로 연습하기 쉽지만 초보자에게는 상당한 기술을 요하는 것이다. 
그러므로 볼이 일정하게 되돌아오지 않으면 연습이 지루하고 힘들어져서 자칫하면 흥미를 잃게 된다. 
이런 현상을 방지하기 위해서는 오목한 형태의 타격 판 상중하 어느 곳에  탁구 공이 맞더라도 소정의 각도만큼 중심 쪽으로 보상하여 떨어짐으로써 탁구대 상판의 일정한 위치에 집중적으로 떨어지게 하는 것을 특징으로 하는 탁구연습기구이다
