    • PURPOSE: A wet electrophotographic printer having an auxiliary intermediate transfer unit for improving the transfer efficiency is provided to improve the transfer efficiency such as the quality of color registration while reducing the manufacturing cost. CONSTITUTION: An auxiliary intermediate transfer unit is arranged to contact with a transfer belt(110) to receive a picture transferred from the transfer belt and retransfer the picture to a recording paper(P). A backup unit(125) is arranged to contact with the auxiliary intermediate transfer unit to transfer the picture to the recording paper. A fusing unit(150) fuses the picture retransferred to the recording paper when the picture is transferred to the recording paper.
    • 目的:提供具有用于提高转印效率的辅助中间转印单元的湿式电子照相打印机,以提高转印效率,例如颜色配准的质量,同时降低制造成本。 构成:辅助中间转印单元布置成与转印带(110)接触以接收从转印带转印的图像,并将图像转印到记录纸(P)上。 备用单元(125)被布置成与辅助中间转印单元接触以将图像传送到记录纸。 当图像转印到记录纸上时,定影单元(150)将转印的照片融合到记录纸上。

    • PURPOSE: An improved transcribing unit of an electrically photographing printer is provided to regularly compress the gap between rollers, to prevent papers from crumpling, tearing and curling. CONSTITUTION: A transcribing unit of a printer contains a transcribing roller(110) and a fixing roller(120) for transcribing a certain image on a paper. One roller of two rollers shapes in a recessed reverse crown and the other roller is composed of a core unit(111) in a right crown shape which matches with the reverse crown and an outer circumference(112) which is flat outer profile by covering with the core unit. Therefore, the unit offsets the difference between pre-speed of two rollers in width direction by keeping the profile matching the right crown and the reverse crown between the fixing roller and the transcribing roller, and prevents papers from curling by intervening the outer circumference between the fixing roller and the transcribing roller.
    • 目的:提供电摄影打印机的改进的转录单元以规则地压缩辊之间的间隙,以防止纸张弄皱,撕裂和卷曲。 构成:打印机的转印单元包含用于将特定图像转印在纸上的转印辊(110)和定影辊(120)。 两个辊的一个辊子形成凹入的反向冠部,另一个辊子由与右侧冠部匹配的右冠形状的芯单元(111)和与外部轮廓平坦的外部轮廓(112)组成, 核心单位。 因此,单元通过保持与正确的冠部匹配的轮廓和定影辊和转录辊之间的反向冠部来抵消宽度方向上的两个辊子的预速度之间的差异,并且通过插入定影辊和转录辊之间的外圆周来防止纸张卷曲 定影辊和转录辊。

    • A wet electro-photographic printer includes a transfer/fixing apparatus having a subsidiary intermediate transfer unit disposed to contact a transfer belt to re-transfer an image on a printing paper after receiving the image from a transfer belt, a back-up unit disposed to contact the subsidiary intermediate transfer unit through the printing paper in order to transfer the image transferred to the subsidiary intermediate transfer unit to the printing paper, and a fixing unit fixing the image simultaneously or separately when the image transferred to the subsidiary intermediate transfer unit is re-transferred to the printing paper. The transfer belt includes a single non-elastic layer made of one material selected from polyimide, polycabonate and ethylene-tetrafluoroethylene. The subsidiary intermediate transfer unit includes a subsidiary intermediate transfer roller having an elastic layer of a predetermined thickness to which a voltage of a predetermined polarity is supplied to attach the image formed on the transfer belt to the printing paper, and contacting the transfer belt with a predetermined pressure. Accordingly, the printer having the subsidiary intermediate transfer unit can improve a transfer efficiency, such as color registration quality, and reduce manufacturing expenses as the subsidiary intermediate transfer unit having the elastic layer with the predetermined thickness, and the transfer belt having the single thin regular non-elastic layer are used so that the image formed on the transfer belt is not directly transferred to the printing paper but transferred and fixed through the subsidiary intermediate transfer unit.
    • 湿式电子照相印刷机包括具有辅助中间转印单元的转印/定影设备,辅助中间转印单元设置成接收转印带以在从转印带接收图像之后将图像重新转印到打印纸上,支撑单元设置成 通过打印纸接触辅助中间转印单元以将转印到辅助中间转印单元的图像转印到打印纸上;以及定影单元,当转印到辅助中间转印单元的图像被重新转印时,同时或单独地固定图像 - 转移到打印纸上。 转印带包括由选自聚酰亚胺,聚碳酸酯和乙烯 - 四氟乙烯中的一种材料制成的单一非弹性层。 辅助中间转印单元包括辅助中间转印辊,该辅助中间转印辊具有预定厚度的弹性层,预定极性的电压被供应到辅助中间转印辊,以将形成在转印带上的图像附着到打印纸上,并且使转印带与 预定的压力。 因此,具有辅助中间转印单元的打印机可以提高诸如颜色配准质量的转印效率,并且降低作为具有预定厚度的弹性层的辅助中间转印单元的制造费用,并且转印带具有单个薄规则 使用非弹性层,使得形成在转印带上的图像不直接转印到打印纸上,而是通过辅助中间​​转印单元转印和固定。
