ABSTRACT:
A writing tool comprised of a head member, a refill, a return spring, and a cam mechanism for projecting the top of the refill out of or retracting it into the head member comprised of cam body, a rotation cam, and cam bar. The cam body is attached to the head member, and the rotation cam is located near the head member. Since the cam mechanism is located near the head member, the length of the writing tools may be short, therefore compact small writing tools can be formed.
