REWRITABLE VISIBLE INFORMATION RECORDING CARD AND REWRITING DEVICE

摘要

PURPOSE: To obtain a card for easily readably and rewritably print visible information by providing a reversibly variable to a transparent or non- transparent state heat sensitive layer according to a temperature on a card base plate, and thermally printing or erasing it. CONSTITUTION: A film 16 obtained by constituting a protective layer 12, a heat sensitive layer 10 and a support layer 14 as indicated by a broken line in an integral film state is adhered to a base plate 8. The film 16 made of the layer 10 is emulsified in a non-transparent state, and becomes transparent at temperatures of 80 to 100 degrees irrespective of a thickness of the sensitive layer, and becomes emulsified at temperatures of 101 degrees or higher.
