ABSTRACT:
Upon depressing a knock rod in a state of writing of FIG.8A, a cam protuberance3bof a rotor turns rightward to assume a position shown in FIG.8B. Upon removing a finger, the cam protuberance3bturns sliding on a tilted surface, arrives at a position shown in FIG.8C through a first vertical motion (distance d) and, further, arrives at a position shown in FIG.8D through a second vertical motion (distance e). Here, a tilted surface of cam protuberance3bcomes in collision with a tilted surface of an inner cylinder cam2btwice, and shocks are transmitted to a refill7.By forming a step between the front half and the rear half of the tilted surface of the inner cylinder cam2b,however, a distance of vertical motion of the cam protuberance3beach time is shortened to decrease the shock of collision imparted to the refill each time.
