PROBLEM TO BE SOLVED: To obtain the light transmission and to facilitate the mounting or removal of a rolled screen by forming the screen by printing a heating circuit by flexible resin composition mixed with metal powder on a flexible film having the light transmission and electric insulation, and holding the screen in a hanging state. SOLUTION: A screen 4 is fixed at its upper end to a winding shaft 3 supported to the body 2 of a rolled screen type heater 1, and a weight bar 5 is mounted at the lower end. The screen 4, for example, uses a composite film obtained by laminating a polyethylene PET (terephthalate) film 4b on nonwoven fabric or fabric 4 using PET fiber and flame-proofing it, a heating circuit 7 is printed by flexible resin composition mixed with metal powder on the film 4b, and laminating the film 4b of another composite film on the printed surface. The screen 4 is held in a hanging state, and can be wound up and contained at the time of no use. |
