PEN LEAD BODY

摘要

A writing instrument has a metal writing point formed by a bundle of fine metal wires, which at one end portion of the bundle are laterally compressed and held adjacent to each other with capillary passages between them. A substantially hemispherical tip is formed at the end surface of the end portion and a substantial part of the remainder of the bundle has a longitudinally extending hollow space at the center thereof. A long permeable ink feeding core is inserted into a hollow space for feeding ink to the passages in the tip and the bundle is encased in a cylinder which may be incorporated in a pen having an ink cartridge from which ink is supplied to the core. The compressed wires are durable and can be provided with a smooth hemispherical surface which moves smoothly over the paper. The passages and the core ensure a steady supply of ink. The writing point also enables sufficient pressure to be applied when writing for making copies with carbon or copy paper.
