    • 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.
    • 位于传送路径的一侧或另一侧上的激光重写装置通过其被固定有热可逆记录介质的待传送物体沿预定传送方向传送。 激光重写装置向热可逆记录介质发射激光并重写图像。 激光写入装置包括:图像擦除装置,其向热可逆记录介质发射激光并从热可逆记录介质擦除图像; 以及位于图像擦除装置的预定输送方向下游侧的图像记录装置,并通过向热可逆记录介质发射激光来记录新图像。 图像擦除装置和图像记录装置具有相对于预定传送方向在相同侧的端部处发射激光的各个激光发射部。
