发明名称 Mechanical pencil with rotary discharge member
摘要 A mechanical pencil includes a tube-like housing having lead cavities annularly provided around an operating central rod. Leads from the cavities are discharged into a lead guiding passage through a rotary lead discharge member which is provided above the lead guiding passages and has a lead discharge passage. The lead discharge member is cooperatively associated with the rod so as to turn, upon depression of the rod, between a first position in which the lead enters the lead discharge passage from one of the lead cavities and a second position in which the lead enters the lead guide passage from the lead discharge passage.
