Abstract:
A mechanical pencil comprising: a main body; a lead-feeding mechanism disposed in the main body for gripping a lead at a lead-gripping position and for feeding the lead to an advanced position; a mouthpiece connected to the main body; a slider slidably fitted in the mouthpiece; a lead-holding member disposed in the slider for frictionally holding the lead fed to the advanced position; a slider-resisting member disposed in contact with the slider for applying a frictional resistance to the slider larger than a frictional resistance of the lead-holding member; and control means for controlling the frictional resistance applied to the slider by the slider-resisting member to bring the slider-resisting member in slight contact with or non-contact with the slider so that the frictional resistance of the slider-resisting member is smaller than the frictional resistance of the lead-holding member in a region corresponding to a return amount of the lead when the lead fed to the advanced position by the lead-feeding mechanism returns to the lead-gripping position.
