Abstract

PURPOSE: To move a writing-part greatly with less depress of push-part by placing cam surfaces of a cam crossly and abutting a pressing cam part of the push-part on both surfaces of the cam to push to the cross point.
CONSTITUTION: When the push-part 7 is depressed, the part 7 drives the cam 6 sliding on the both cam surface 2a and 3a simultaneously from the contact point P to the direction of the arrow mark 1. The cam surface 2a formed on the inner cylinder 2 fixed in the body 1 and the cam surface 3a of the sliding cam 3 are slanting to the opposite direction each other and crossed at the contacted point P. As the cam surface 2a is fixed and projection 3b on the cam 3 is in the long groove 2c on the inner cylinder 2, the cam 6 pushes up the cam part 3 to the direction 1a of the top opening of the cylinder. The slanted angles of the cam surface 2a and 3a are recommended at about 45° for smooth operation and for realizing the moving pass L of the cam part 3 moving together with the writing part 5 double to the moving pass of the cam 6.
