본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
제1도는 본 발명에 따른 구구단 학습기의 일부절개 사시도, 제2도는 제1도에 있어서의 부분확대 및 구성요소의 분해사시도, 제3도는 누름돌기를 누르지 않은 상태에서의 단위암실의 단면도.1 is a partially cutaway perspective view of a multiplication table learner according to the present invention, FIG. 2 is an exploded perspective view of a part enlargement and components in FIG. 1, and FIG. 3 is a sectional view of a unit dark room without pressing the pusher.

Claims (2)

  1. 밑면과 상하벽 및 좌우벽이 일체로 되어 있고 그 상부면은 일정문자 부분만을 남기고 나머지 부분이 불투명하게 코팅된 색유리판을 덮어서 된 격자상의 암실 내부에서, 스프링의 누름돌기의 눌링에 의해 연동되어 회전하는 백색 불투명 회전판이 상기 색유리판 이면에 밀착됨으로써 일정문자를 가시화(可視化)시킬수 있는 것을 특징으로 하는 문자표시방법.The bottom, upper and lower walls and the left and right walls are integrated, and the upper surface is interlocked by the pressing of spring push-buttons in the dark room of the lattice, which is covered with colored glass plates coated with an opaque coating, leaving only a certain letter portion. And a white opaque rotating plate adhered to the back surface of the colored glass plate so that certain characters can be visualized.
  2. 상단에는 래크와 치차 및 스프링의 탄성에 의해 구동하는 숫자선택버튼이 구성되어 있고 하단에는 불투명 합성수지재로 된 다수의 격자상의 암실이 일체로 사출성형되어 있되 각 암실의 측벽에는 회전판의 회전축 봉이 삽입되기 위한 요흠이 가로방향의 일직선상에 축설되어 있으며, 상기 회전축 봉에는 상부에 수직돌기가 형성되어 있고 하부에는 수평절곡부가 연장되어 있는 불투명재질의 백색 회전판이 회전자재토록 다수 관통되어 있되 상기 회전판 상부에 돌출되어 있는 수직돌기는 스프링의 수평돌기 아래에 놓여짐으로써 스프링의 누름돌기를 누름에 따라 연동되어 눌려져 회전판을 회전시킬수 있도록 설치되며 상기와 같은 각 암실의 상부면에는 각 구구단 계산숫자에 상당하는 숫자 부분만 남기고 나머지 부분이 불투명하게 코팅된 색유리판이 일체로 씌워지되 상기 색유리판에는 상기 스프링의 누름돌기가 돌출되도록 일정 구멍이 천공되어 있는 것을 특징으로 하는 구구단 학습기.The upper part consists of a number selection button driven by the elasticity of the rack, gear and spring, and the lower part of the lattice-shaped dark chamber made of opaque synthetic resin is integrally injection-molded. In order to be arranged on a straight line in the horizontal direction, the rotating shaft rod is formed with a vertical projection on the upper portion and a horizontal rotating plate of the opaque material with a horizontal bending portion extending at the bottom of the rotating material through a large number of rotating plate The protruding vertical projection is placed below the horizontal projection of the spring so that it is interlocked with the pressing projection of the spring and is installed to rotate the rotating plate. The upper part of each darkroom has a number part corresponding to each multiplication table number. Colored glass with opaque coating leaving only the remainder Jidoe covered with a glass plate, the integral and the color multiplication learning machine characterized in that the perforation hole so as to project a certain group nureumdol of the spring.
