LASER ERASING APPARATUS AND LASER ERASING METHOD

摘要

A laser erasing apparatus includes a conveyance unit to move a reversible thermal recording medium having display information thereon at a predetermined moving speed, the reversible thermal recording medium reversibly changing a color tone thereof depending on a temperature; and a laser erasing unit configured to erase the display information by irradiating the reversible thermal recording medium with a laser beam while the reversible thermal recording medium is moving and by deflecting the laser beam at a predetermined scanning speed lower than the predetermined moving speed in a same direction as a moving direction of the reversible thermal recording medium.
