Abstract
A magnetic pen for drawing lines on the main surface of a magnetic display sheet consisting of a plurality of microcapsules in which oily liquid having photoabsorptive ferromagnetic powder and photoreflective non-magnetic powder are mixed in sealed relationship, and wherein the magnetic pen includes a core member having a spherical crown shape, a magnet constituting part of a notched surface of the core member, the core member being supported by the pen such that the notched surface of the core member protrudes from the tip of the pen and a spherical contraposition is generated by a part of the spherical surface of the core member, and wherein the notched surface of the core member is brought into contact with the main surface of the magnetic display sheet by the force of a stroke drawing line.

A writing device comprising:
- a magnetic display sheet;
- and
- a magnetic pen for contacting the magnetic display sheet at an angle to the magnetic display sheet, the pen having a body and a core pivotally mounted in the body to pivot with respect to the body, the core having an exposed planar surface serving as an outer resistant surface of the pen with a magnet forming a portion of the planar surface such that when the pen contacts the magnetic display sheet, the angle of the planar surface with respect to the body changes to correspond with the angle of the pen with respect to the magnetic display sheet.
