摘要： A laser rewriting apparatus positioned on one side or the other side of a conveyance path through which a to-be-conveyed object on which a thermoreversible recording medium is affixed is conveyed in a predetermined conveyance direction. The laser rewriting apparatus emits laser light to the thermoreversible recording medium and rewrites an image. The laser writing apparatus includes an image erasing apparatus that emits laser light to the thermoreversible recording medium and erases the image from the thermoreversible recording medium; and an image recording apparatus positioned on the predetermined conveyance direction downstream side of the image erasing apparatus and records a new image by emitting laser light to the thermoreversible recording medium. The image erasing apparatus and the image recording apparatus have the respective laser light emitting parts from which the laser light is emitted at ends on the same side with respect to the predetermined conveyance direction.
