    • An image-forming apparatus and sheet feeding device capable of feeding sheets without skewing or multi-feeding of sheets using a small number of side air blowing drive sources. The sheet feeding device has a plurality of side discharge nozzles comprising side discharge outlets for blowing air onto the respective side edge surfaces of a paper stack, and two sirocco fans which are communicatively connected in series as a side air blowing drive source, and are communicatively connected, via a side discharge drive source chamber and a side discharge relay tube (duct), to the plurality of side discharge nozzles. The respective side discharge nozzles capable of moving in linkage with side fences, and an immovable fixed side discharge nozzle are disposed at different distances from the leading edge of the loaded and set paper stack with respect to a sheet feeding direction.
    • 一种图像形成装置和片材进给装置,其能够使用少量的侧吹风驱动源来进给片材而不会偏斜或多次进给片材。 片材进给装置具有多个侧排出喷嘴,其包括用于将空气吹送到纸叠的各个侧边缘的侧排出口,以及作为侧吹风驱动源串联连接的两个西洛克风扇,并且通信 通过侧排出驱动源室和侧排放中继管(管道)连接到多个侧排出喷嘴。 能够与侧栅栏连动移动的各个侧排出喷嘴和不可移动的固定侧排出喷嘴相对于纸张供给方向设置在与装载纸张堆叠的前缘不同的距离处。

    • Increased manual access spaces are provided even within a more compact printer for the movement or removal of printer components such as paper path baffles to be moved for the removal of jammed sheets and/or other hand or tool insertions by printer users and/or repair personnel. This is provided by automatically reducing the normal operating space occupied or required by at least one operative printer component during a machine shutdown in or near such desired manual access areas. In particular, by replacing at least part of at least one of the present rigid space-consuming air ducts or manifolds in a printer with a collapsible portion adjacent to at least one paper path jam clearance area or other desired manual access area which at least partially collapses upon printer shutdowns removing power from the blower for that air duct to substantially increase unobstructed manual access.
    • 即使在更紧凑的打印机中也可以提供增加的手动访问空间,用于移动或移除打印机部件,例如要移动的纸路径挡板,以便打印机用户和/或维修人员去除卡住的纸张和/或其他手或工具插入 。 这是通过在机器关闭期间自动地减少由该期望的手动访问区域内或附近的至少一个可操作的打印机部件占用或要求的正常操作空间来提供的。 特别地,通过将​​具有可折叠部分的至少一个至少一个现有的刚性空间消耗空气管道或歧管替换为与至少一个纸张路径堵塞间隙区域或其它期望的手动接近区域相邻的可折叠部分,该区域至少部分地 在打印机关机时塌缩,从该风道的鼓风机上移除电力,从而大大增加无阻碍的手动进入。
