IMAGE ERASING APPARATUS AND IMAGE ERASING METHOD

摘要

It is made possible to uniformly erase an image recorded on a thermo reversible recording medium. The image erasing apparatus 2000 includes an LD array 1 which emits a laser light whose cross section has a line shape; optics which include at least one cylindrical lens which converts into a converging light which converges in a width direction a line shaped laser light which is emitted from the LD array 1 and emits the converging light; and a mono axial galvano mirror 5 which deflects the laser light emitted from the optics in the width direction to scan the deflected laser light onto the thermo reversible recording medium.
