PURPOSE:To obtain composite writing utensils convenient and having good operability, wherein a writing utensil mechanism having a plurality of refills is combined with a mechanism for feeding a bar-like object. CONSTITUTION:When a rear shaft 4 is rotated, either a refill 1 or a refill 2 is selected and projected by an actuating part of a cam main body 10. When the selected refill is a propelling pen, a lead is fed by pushing a rear end of the rear shaft. In addition, when a bar-like object such as an eraser, etc., is used, a rear end operating part of a guide cylinder is held with fingers and rotated, whereby a slider 12 is guided by a spiral groove of the cam main body 10 and a guide groove of the guide cylinder to be moved up, and the eraser or the like is fed from the rear end. |
