PURPOSE:To provide a reversible thermal sheet of simple constitution capable of being electrically adjusted in light transmissivity or hue, a recording erasing method low in power consumption and heat capacity and conserved in energy, a temp. control method of simple constitution and the excellent applied system of the reversible thermal sheet. CONSTITUTION:An applied system of a reversible thermal sheet is constituted of a reversible thermal layer 6 reversibly changed in transparency or hue at a plurality of heating temps. and held to a changed state, a strip like conductive sheet wherein a plurality of mutually insulated conductive wires 1 are parallelly arranged in a laminated state so as to be capable of heating the reversible thermal layer 6, the common electrodes 4 formed to both ends of the stripe like conductive sheet and the electrode 5 connected to a control circuit through a lead wire 3. |
