Abstract: Upon depressing a knock rod in a state of writing of FIG. 8A, a cam protuberance 3b of a rotor turns rightward to assume a position shown in FIG. 8B. Upon removing a finger, the cam protuberance 3b turns 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 protuberance 3b comes in collision with a tilted surface of an inner cylinder cam 2b twice, and shocks are transmitted to a refill 7. By forming a step between the front half and the rear half of the tilted surface of the inner cylinder cam 2b, however, a distance of vertical motion of the cam protuberance 3b each time is shortened to decrease the shock of collision imparted to the refill each time.

Abstract: The object of this invention is to provide a safety knock-type writing instrument. The writing instrument includes a barrel (10) with a cartridge (50), a gear unit (30), and a knock unit (60). The gear unit (30) is positioned on an exterior of the barrel (10) and rotatably seated on a clip (20). The knock unit (60) is provided in the barrel (10), and includes first and second protrusions (61, 62) to engage with the gear unit (30), thus operating the gear unit. In this writing instrument, when the first protrusion (61) of the knock unit disengages from the gear unit (30), the cartridge is retracted into the barrel. Thus, although a user puts the writing instrument, with the cartridge extended, in a pocket without first retracting the cartridge, the cartridge is automatically retracted into the barrel, thus preventing his/her clothing from being stained by the cartridge.
