<p>PURPOSE: To improve the clarity of a line by providing a line-of-magnetic force guide member for guiding a line of magnetic force from one end of an external magnetic member to the other end of the member at the opposite side of a visible magnetic card body with respect to the member. CONSTITUTION: A microcapsule layer 10 for forming a visible display area 9 by arranging a microcapsule 5 on a display unit 7 by binder 8 is formed on a visible magnetic card body 1A. Magnetic flake 3 alterable in an orienting direction according to the magnetic field from a magnetic pen 2 is sealed as an external magnetic member in the microcapsule 5. The unit 7 is displayed by the reflection of a visible incident light according to the orienting direction of a board 6 and the flake 3. A magnetic sheet 11 is provided as a line-of- magnetic force guide member for guiding the line of magnetic force from the one end of the pen 2 to the other end of the pen 2 as the underlay of the body 1A. Thus, the clarity of a line can be improved.</p> |
