PURPOSE:To prevent the deterioration of a recorded image quality and improve the durability of a thermal head. CONSTITUTION:A number of heat-sensitive recording papers 10 are stacked with their heat-sensitive color developing layers upward. Each stack of the heat-sensitive recording papers 10 is sandwiched between two light shielding sheets 11 a and 11b and wholly packaged in a wrapping paper 12. These light shielding sheets 11a and 11b prevent the heat-sensitive recording papers 10 from exposure to outside light and clean the same upon passage through a thermal head. |
