PURPOSE:To prevent a printing surface from being subjected to color development by mistake and scratched by a method wherein the printing surface thermally forming a color is wound in a roll state so as to become inside. CONSTITUTION:Thermal roll paper 17 is wound around a taking-up shaft 17C in a roll form so that the thermal color forming surface being the printing surface thereof becomes inside and mounted in such a state that the leading end of the thermal roll paper 17 is inserted in an insertion port 19 from the upper side of the roll. Therefore, even when an operator touches with or rubs the thermal roll paper by mistake when a electronic calculator equipped with a recording apparatus is carried, color development is eliminated and printing grade is not damaged. |
