PURPOSE:To provide an image forming device using a thermochromic film capable of being easily exchanged in a short time. CONSTITUTION:An engine frame 10 holds a heating roller 3 and a thermal head 4, and is restrained at a driving position. The heating roller 3 is press- contacted to the thernmochromic film 1 to generate tension. On the other hand, the thermal head 4 holds the thermochromic film 1 together with a platen roller 5. The restraining of the engine frame 10 is released and turned in the direction of the arrow A, centering a rotary shaft 10a, so that the heating roller 3 and the thermal head 4 can be separated from the thermochromic film 1, at the same time. |
