ABSTRACT:
In a multiplex writing instrument, a plurality of writing elements including at least one mechanical pencil are provided in a barrel body and are respectively urged rearward by resilient members, and the writing elements are arranged so that a selected writing element is projected from the barrel body when a pressure member secured to a rear end of the selected writing element is made to move forward. The mechanical pencil comprises an external member connected to a corresponding pressure member, and a lead feeding mechanism disposed inside the external member, and a knock member for operating the lead feeding mechanism is disposed on the corresponding pressure member. In another mode, the mechanical pencil comprises an external member non-rotatably connected to a corresponding pressure member, and a lead feeding mechanism disposed inside the external member. A knock member for operating the lead feeding mechanism is disposed on the corresponding pressure member, and the external member is a flexible member.
