Abstract
A mechanical pencil of the type having a push-button lead-feeding mechanism is provided with a space into which a replaceable cartridge containing leads can be inserted. The cartridge has a lead outlet opening which is blocked by a closure that is moved out of the way upon such insertion so that the leads can thereupon move sequentially into the lead-feeding mechanism, permitting a user to write until all leads in the cartridge are used up.
