portion of the cam grooves 11a 12a and 13a under this condition the pattern indication board 12 is shifted in the left direction and the board 11 is shifted in the right direction while the board 13 remains in the rightward position thus each of the second mode patterns comes to each of the pattern indication windows 2 while the first mode patterns are positioned behind the masked part of the front panel 1 and are not indicated finally when the mode changing key 4 is switched to the 3rd position iii the pattern indication board 13 is shifted in the left direction and the board 12 is shifted in the right direction then the third mode patterns are indicated through the respective pattern indication windows 2 of the front panel 1 in the second and third modes any patterns may be optionally selected in each column by repeatedly operating the corresponding pattern selection key 3 just in the same manner as in the case of the first mode thus according to the invention a number of pattern indication boards are accumulated in one place of the sewing machine and those pattern indication boards each of which has many patterns imprinted thereon may be selectively designated by operation of a.
