摘要

A roll sheet has a release paper (302) as a base sheet. A recording paper (301) is attached to the release paper via an adhesive layer (308) so that the recording paper can be peeled off from the release paper. First and second peel-away areas (303,304) are formed on both side edges of the roll sheet in the widthwise direction thereof by peeling off both widthwise edges of the recording paper from the release paper to allow the release paper to be exposed at the both side edges of the roll sheet. Sensor marks (305) are printed on the release paper (302) as being entirely shifted from the peel-away areas (303,304). This ensures that the roll sheet has a uniform thickness over the entire area of each sensor mark, thereby ensuring that each sensor mark has uniformities in its reflectivity and transmittance with respect to incident light.
