ABSTRACT:
A magnetic writing implement comprises a tubular casing with a writing unit which is frictionally interfitted with the conical end of the casing, a storage tube slideably engaged within the casing for storing a plurality of writing units therein, an ejector and a push tube connected with the front end and rear end of the storage tube, respectively for ejecting the writing unit from the conical end of the casing as its writing point becomes blunt for replacement by a sharpened unit, and a stopper inserted in the rearmost portion of the push tube to prevent the stored writing units from slipping out of the tube. Each writing unit carries a sharpened lead pencil element or the like at its front portion and includes a piece of magnet at its rear end. The ejector and the stopper also contain a piece of magnet at each of their front ends. Each of the pieces of magnet in the present writing implement are secured with the same magnetic pole oriented in the same direction, so that each rear end of the writing unit has a magnetic pole different from those at the front ends of the ejector and the stopper. Therefore, the rear end of each writing unit may be attracted at the front end of the ejector or stopper by magnetic force.
