<p>PURPOSE:To provide an image data recording apparatus capable of being enhanced in shafety against generation of heat and capable of performing the writing or erasure of an image by an extremely simple structure by performing temp. control using a shape memory alloy. CONSTITUTION:In an image data recording apparatus using an image display sheet coated with a thermochromic material becoming transparent by the heating to prescribed temp. and becoming opaque by the heating to different prescribed temp. and capable of displaying a image by utilizing the change of the light transmittance of the image display sheet, an image writing device 16 equipped with a heating element 12 generating heat by the supply of a current in order to write an image on the image display sheet and a shape memory alloy 16 having transformation temp. almost equal to the prescribed temp. making the thermochromic material opaque and controlling the temp. of the heating element 12 is provided.</p> |
