Abstract

PURPOSE:To widen the movable range of a pen by increasing the density of magnetic flux by constituting a magnetic circuit by holding a center pole at both its sides with permanent magnets, and then equipping them in a yoke. CONSTITUTION:A center pole 2a is held between rare earth permanent magnets 5 having high characteristics and equipped at both the sides of the center pole 2a, and yokes 6 are provided on the outside of the magnets 5; while the center pole 2a and permanent magnets 5 are surrounded with yokes 7, the yokes 6 and yokes 7 are connected together to constitute a magnetic circuit. The center pole 2a is wound with a coil 3 and a main shaft is inserted into a driving shaft hole 1 and held by a bearing. Then, a pen tip is equipped to the main shaft.
