    • A laser sublimation type color video printer includes a plurality of dye tanks for accommodating solid powder form sublimating dyes. The dye tanks are communicated with liquid dye vaporizing sections via respective accommodating passages which are formed as capillary tubes provided with heating elements for liquefying dyes introduced from the dye tanks. The heating elements may also be active to heat the surface of photographic paper via a protective layer of the head portion of the printer. Each of the vaporizing sections comprises a plurality of vaporizing pores having a light-heat converting element projected thereinto from a head base of the printer. A laser source is mounted over the light-heat converting element, which may comprise a heat resistant light transmitting portion having a light-heat converting layer disposed on a lower end thereof. The vaporizing pores allow a sufficient amount of liquid dye to be adhered to the lower side of the light-heat converting element to be vaporized and adhered to the surface of the photographic paper upon irradiation by a laser beam from the laser source. An area of the light-heat conversion element is limited to an area which may be covered by the vaporized dye according to an irradiation operation.
    • 激光升华型彩色视频打印机包括用于容纳固体粉末形式升华染料的多个染料罐。 染料罐通过相应的容纳通道与液体染料蒸发部分连通,所述通道形成为毛细管,毛细管设置有用于液化从染料罐引入的染料的加热元件。 加热元件还可以有效地通过打印机头部的保护层来加热照相纸的表面。 每个蒸发部分包括多个蒸发孔,其具有从打印机的头部基座突出的光热转换元件。 激光源安装在光热转换元件上,光热转换元件可以包括具有设置在其下端的光热转换层的耐热透光部分。 蒸发孔允许足够量的液体染料粘附到光热转换元件的下侧,以便通过来自激光源的激光束照射时被蒸发并附着到相纸的表面。 光热转换元件的区域被限制为可以根据照射操作被蒸发的染料覆盖的区域。

    • A printing device according to the present invention includes a dye tank for containing a powdered vaporizable dye, an entrance section for liquefying the powdered vaporizable dye and a vaporizing section for radiating a laser light beam onto the liquefied dye transported to it by the entrance section for vaporizing the liquefied dye for thermal transcription of the vaporized dye onto a photographic paper. In this manner, printing may be made without employing an ink ribbon or a thermal head and hence the saving in power and the reduction in size and costs of the printing device may be achieved. Besides, the printing time may be shortened, while the size of the printing paper, may be set freely.A photographic paper according to the present invention includes a light absorbing layer between a receptor layer and a photographic paper base. Since the light absorbing layer is capable of absorbing the light efficiently for evolving heat efficiently, the receptor layer may be heated directly to assure a high quality of the printed picture.
    • 根据本发明的打印装置包括:用于容纳可粉化可粉化染料的染料罐,用于液化可粉化可粉化染料的入口部分和用于将激光束辐射到由入口部分运送到其上的液化染料上的蒸发部分, 将液化的染料蒸发以将蒸发的染料热转印到相纸上。 以这种方式,可以在不使用墨带或热敏头的情况下进行打印,因此可以实现打印装置的功率节省和尺寸和成本的降低。 此外,可以缩短打印时间,同时打印纸的尺寸可以自由设定。 根据本发明的照相纸包括在受体层和相纸基底之间的光吸收层。 由于光吸收层能够有效地吸收光以有效地放出热量,所以可以直接加热接收层,以确保印刷图像的高质量。

    • An ink sheet (3) is wound around rollers (6), and a recording sheet (4) is placed with a space (d) between the ink sheet (3) and the recording sheet (4) and is advanced. The thickness of the space (d) is a value in the range of 1 to 100 .mu.m. The ink sheet (3) is irradiated with a laser beam (L) emitted by a laser (5) to transfer the dye contained in a dye layer formed on the ink sheet (3) from the ink sheet (3) to the recording sheet (4) for printing. The dye layer of the ink sheet (3) is replenished with the dye (30, 30A) heated and fused by a heater (9) by a dye supply unit (7) at a position other than a position where the ink sheet (3) is irradiated with the laser beam (L). Since the ink sheet and the recording sheet are held with the space (d) having a thickness in the range of 1 to 100 .mu.m, the dye once transferred to the recording sheet is not transferred from the recording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed. Since the dye layer of the ink sheet is replenished with the dye, the ink sheet can be repeatedly used, so that no waste is produced.
    • 油墨片(3)缠绕在辊(6)上,记录纸(4)在油墨纸(3)和记录纸(4)之​​间放置有空间(d)并且前进。 空间(d)的厚度为1〜100μm的范围。 用由激光(5)发射的激光束(L)照射油墨纸(3),以将形成在油墨纸(3)上的染料层中所含的染料从油墨纸(3)转印到记录纸 (4)打印。 油墨片(3)的染料层由染料供给单元(7)在除了油墨片(3)的位置以外的位置被加热器(9)加热熔化的染料(30,30A)补充 )被激光束(L)照射。 由于油墨片和记录纸被保持在厚度在1至100μm范围内的空间(d),所以一旦转印到记录纸上的染料不会从记录纸转移到油墨纸上,所以 可以印刷具有较高密度的清晰图像。 由于油墨片的染料层被染料补充,所以可以重复使用油墨片,因此不会产生浪费。
