DEVICE FOR RECORDING, ERASING AND DISPLAYING INFORMATION

摘要

PURPOSE:To permit display of information by mixing or laminating a heat sensitive material which attains a uniform transparent state or opaque state when heated and cooled to a specific temp. and material which has the absorption at the wavelength of a light source to constitute an information recording body and heating such information recording body to a specific temp. range. CONSTITUTION:The information recording body (belt) 40 is rotationally driven in an arrow direction by the rotation of a driving pulley and the outside surface on the tense side of the belt 40 moves and passes in a display image viewing window 20 part in the arrow direction. The image formed like a sheet is erased in an erasing part 90 as necessary for erasing. The erasing of the image is executed by heating the sheet and adjusting the cooling rate. The information recording body on the belt 40 is heated and is changed from the transparent state to the opaque state when said belt passes an optical device 100 in the turning process thereof. The information to be displayed is thus visualized. The recording part in then turbid state moves to the inside of the range of the window 20 and once stops there, by which the image is displayed in the window 20 part.
