    • Disclosed is a sheet conveying mechanism for an original to be reproduced in a reproducing apparatus, comprising means, including a rotatable drum having an air-permeable circumferential shell surface, for supporting the original; non-rotatable means disposed within the drum for dividing the space within the drum and the circumferential shell surface of the drum into three separate regions; means associated with the drum for selectively producing positive and negative pressure within each of the separate drum regions; means for exposing and scanning the original, positioned adjacent a first one of said separate drum regions; means, associated with the drum and being responsive to movement of the original around the drum, for controlling the pressure-producing means; and first and second means, cooperating with the drum and located adjacent the circumferential shell surface of the drum in the area of a second one of the separate drum regions, for transporting the original around the drum.

    • Disclosed is a thermal pressure fixing device for a copier, comprising a pressure roll and a fixing roll for heating and pressing an image-receiving material carrying a toner image, whereby during the passage of the image-receiving material between the rolls the latter are in pressure contact with each other, whereas during a standstill of the copier or in the case of a copier malfunction, the pressure of the rolls is discontinued. There are provided a device for lifting the pressure roll toward the fixing roll and for separating the two rolls, and a clutch and brake mechanism interacting with this device. Resilient elements adapt the center distance between the pressure roll and the fixing roll to the changes occurring in diameter of these rolls, in such a way that the preset roll pressure between the rolls remains constant.
    • 公开了一种用于复印机的热压定影装置,包括压辊和用于加热和加压承载调色剂图像的图像接收材料的定影辊,由此在图像接收材料在辊之间通过期间 彼此压力接触,而在复印机静止期间,或者在复印机故障的情况下,辊的压力停止。 提供了一种用于将压力辊提升到定影辊并分离两个辊的装置,以及与该装置相互作用的离合器和制动机构。 弹性元件使压辊和定影辊之间的中心距离适应于这些辊的直径发生的变化,使得辊之间的预设辊压力保持恒定。

    • Disclosed is a roll-fusing apparatus comprising a heated fusing roller and a pressure roller which form a roller gap therebetween. The shape of the non-cylindrical roller core and the coating of the pressure roller makes it possible to fuse the toner images on copy supports which remain free of wrinkles after passing through the roller gap. In addition, duplication of the copy image does not occur up to DIN A1 size copies. The roller core and the coating of the pressure roller, comprising a silicone elastomer coating and a shrunk-on tubing have varying thicknesses over the length of the roller. As a result, the speed of passage of the copy support at the edges of the roller gap is modified, compared with the speed of passage obtained with a pressure roller having a cylindrical roller core and a cylindrical coating.
    • 公开了一种辊熔融设备,其包括加热的定影辊和在其之间形成辊隙的加压辊。 非圆柱形辊芯的形状和压辊的涂层使得可以将经过辊隙之后保持无褶皱的复印支架上的调色剂图像熔合。 此外,根据DIN A1尺寸的复印件,复印图像的复制也不会发生。 包括硅酮弹性体涂层和收缩管的辊芯和压辊的涂层在辊的长度上具有不同的厚度。 结果,与用具有圆柱形辊芯和圆柱形涂层的压力辊获得的通道速度相比,改变了辊间隙边缘处的复制载体的通过速度。
