Abstract:
A thermal transcription printing device comprising:a powered dye tank in which powdered dye is stored;an entrance section which is connected to said dye tank to receive dye therefrom;a vaporizing section which is contiguous with said entrance section;a heating member which is disposed in said entrance section and which has a portion which projects into said dye tank and which heats and liquifies the powdered dye in said dye tank, said heating member extending to said vaporizing section to as to conduct liquified dye thereto;a semi-transparent light absorbing layer disposed in said vaporizing section, said light absorbing layer converting laser light which passes therethrough into heat, the heat produce by said semi-transparent light absorbing layer vaporizing the liquified dye which has been conducted into said vaporizing section by said heating member;a source of laser light which selectively directs beams of laser light through said semi-transparent light absorbing layer; andvapor openings formed in a lower portion of said vaporizing section which diffuse vaporized dye from said vaporizing section to a receptor layer of a sheet of photographic paper, said vapor openings being arranged to also transmit laser light from said source of laser light and which has passed through said semi-transparent light absorbing layer, to said photographic paper.
