Image erasing apparatus and image erasing method

摘要

A method for uniformly erasing an image recorded on a thermo-reversible recording medium. The image erasing apparatus includes an LD array, 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 and emits the converging light; and a mono-axial galvano mirror 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.

主权项

1. An apparatus, comprising:
a light source configured to emit laser light whose cross section has a line shape; optics configured to convert the laser light emitted from the light source to converging light which converges in a width direction to emit the converging light, and parallelize the laser light emitted from the light source in a length direction to emit the parallelized laser light; and a scanning unit configured to deflect, in the width direction, the laser light emitted from the optics to scan the deflected laser light on a thermo-reversible recording medium, wherein the apparatus is configured to scan the deflected laser light onto the thermo-reversible recording medium on which an image is recorded to erase the image.
