<p>PURPOSE:To obtain a finer display by initializing a part except a display part and a printing part by a degaussing head and a contrast adjusting head. CONSTITUTION:A magnetic card 21 with a display part is inserted from a port 3 and elected from an ejecting port 4 by a transfer means 6. The display part of the card 21 is initialized magnetically by the degaussing head 11. Then, a prescribed printing is performed by a printing head 12, thereafter, the magnetic condition of an unprinted part is initialized by applying AC magnetic field smaller than the coercive force of a written card display part printing to a card display part by the contrast adjusting head 13, thus, the printing comes to the surface finely. Then, the display remarkably easier to see than a conventional display is obtained.</p> |
