MECHANICAL PENCIL WITH SIDE BUTTON AND ERASER DISPENSER AND METHOD OF ASSEMBLY
First Claim
1. A mechanical pencil comprising:
- a barrel extending in a longitudinal direction, a lead-propelling mechanism, a lead reservoir, a side button, and an eraser-propelling mechanism having a helical cam, the lead-propelling mechanism, the lead reservoir, the eraser-propelling mechanism, and the side button being at least partly housed inside the barrel, the lead-propelling mechanism, the lead reservoir, and the eraser-propelling mechanism being prevented from rotating about the longitudinal direction relative to one another and relative to the side button, and the side button is prevented from rotating about the longitudinal direction relative to the barrel.

Abstract
A mechanical pencil includes a barrel extending in a longitudinal direction, a lead-propelling mechanism, a lead reservoir, a side button, and an eraser-propelling mechanism having a helical cam. The lead-propelling mechanism, the lead reservoir, the eraser-propelling mechanism, and the side button are at least partly housed inside the barrel. The lead-propelling mechanism, the lead reservoir, and the eraser-propelling mechanism are prevented from rotating about the longitudinal direction relative to one another and relative to the side button, and the side button is prevented from rotating about the longitudinal direction relative to the barrel.

12. A method of assembling a mechanical pencil comprising the steps of:
-
providing a barrel extending in a longitudinal direction, a lead-propelling mechanism, a lead reservoir, an eraser-propelling mechanism having a helical cam, and a side button; preventing the side button from rotating about the longitudinal direction relative to the barrel; inserting the lead-propelling mechanism into the barrel and preventing the lead-propelling mechanism from rotating about the longitudinal direction relative to the side button; assembling the eraser-propelling mechanism and the lead reservoir together and preventing the eraser-propelling mechanism from rotating about the longitudinal direction relative to the lead reservoir; and inserting the lead reservoir and the eraser-propelling mechanism into the barrel and preventing the lead reservoir from rotating about the longitudinal direction relative to the lead-propelling mechanism. - View Dependent Claims (13, 14)
