<p>PROBLEM TO BE SOLVED: To provide a magnetic element display device such as an electronic blackboard or the like capable of redisplaying two-dimensional information display of which was carried out in the past. SOLUTION: A recording display part 1 is constituted by arranging a plurality of magnetic display elements 11 wherein different colors are applied to respective N and S poles. A locus of a tip of a recording tool 2 is displayed by those respective magnetic display elements. When a display content is preserved, scanning with a record reproducing head 4 is carried out, a direction of each magnetic display element is read via the head 4, and written in a memory 6 capable of being attached and detached via an input-output control part 7. In that case a positional control part 8 supplies a write address corresponding to a head position to the memory 6. If necessary, two-dimensional information in the memory 6 is read, driving of each magnetic display element based on the read data is carried out by the input and output control part 7 and the head 4, and redisplay of the preserved two-dimensional information is carried out.</p> |
