Abstract

PURPOSE: To even the key depressing forces irrespective of the location of each key by a method wherein each key depressing operation is divided into the first depression where the key is stopped by its collision with a rod-shaped stopper and the second depression where the key is stopped at the bottom portion of a key guide slit.
CONSTITUTION: When a one-action operating key belonging to a lower-stage group B, say a key 1, is depressed, the key 1 collides with a rod-shaped stopper 5 for the lower-stage group. Since the stopper 5 is being pushed upward by a spring 11, the depression of the key 1 is once stopped by the elastic force of the spring 11, during which a pawl 30 of a key lever 14 rotates counterclockwise on the sloped surface of a lever 27. In this case, since a projection 24 is present on the upper surface of the lever 27 and it enters into the rotational locus of the teeth 23 of a snatch roll 22, the projection 24 is kicked by the teeth 23 and moves to the position on the center line. Accordingly, the lever 18' is abruptly rotated to the position on the center line, so that the upper end of the lever 18' pulls a link 21 to rotate a type bar operating piece 20 counterclockwise, thereby conducting a printing operation or the like.
