    • There is provided a sheet processing apparatus that is capable of preventing sheets conveyed to the sheet processing apparatus from being skewed, wrinkled, damaged, or jammed, and prevent sheets stored in the sheet processing apparatus from being misaligned. The sheet processing apparatus receives a sheet discharged from an image forming apparatus comprising fixing rollers that hold and convey a sheet on which is formed an image at a first conveying speed and with a first conveying force, discharge rollers disposed downstream of the fixing rollers in a sheet conveying direction, for conveying the sheet at a second conveying speed higher than the first conveying speed and with a second conveying force smaller than the first conveying force, and a controller that determines whether a trailing end of the sheet is released from the fixing rollers. In the sheet processing apparatus, sheet discharge rollers convey the received sheet, and a controller sets the conveying speed of the sheet discharge rollers to the first conveying speed while the sheet is being conveyed by all of the fixing rollers, the discharge rollers, and the sheet discharge rollers, and sets the conveying speed of the sheet discharge rollers to the second conveying speed after the controller determines that the trailing end of the sheet is released from the fixing rollers.
    • 提供一种片材处理装置,其能够防止输送到片材处理装置的片材歪斜,起皱,损坏或卡住,并且防止存储在片材处理装置中的片材不对准。 纸张处理装置接收从图像形成装置排出的纸张,该图像形成装置包括定影辊,该定影辊保持并输送以第一输送速度形成图像的纸张和第一输送力,排出辊设置在定影辊的下游 片材输送方向,用于以比第一输送速度高的第二输送速度和小于第一输送力的第二输送力输送纸张;以及控制器,其确定纸张的后端是否从定影辊释放 。 在片材处理装置中,片材排出辊输送接收的片材,并且控制器将片材排出辊的输送速度设定为第一输送速度,同时片材被所有定影辊,排出辊和 片材排出辊,并且在控制器确定片材的后端从定影辊释放之后,将片材排出辊的输送速度设定为第二输送速度。

    • An image forming apparatus includes a feeding unit for sequentially feeding a plurality of originals to an exposure plate, an exposure unit, which is movable along the exposure plate, for exposing the original on the exposure plate, an image forming unit for forming on a sheet an image on the original that is exposed by the exposure unit, and a control unit for providing either a first copying operation, in which the original is shifted by the feeding unit while the exposure unit is halted to perform copying, or a second copying operation, in which the exposure unit is shifted while the originals that are fed by the feeding unit are halted on the exposure plate. When the control unit executes a first mode in (e.g. copies>1) which the second copying operation is performed following the first copying operation, the feeding unit feeds the originals while maintaining a first constant distance between a leading end of a preceding original and a leading end of a succeeding original, and wherein, when the control unit executes a second mode (e.g. copies=1) in which only the first copying operation is performed, the feeding unit feeds the originals while maintaining a second constant distance between a trailing end of a preceding original and a leading end of a succeeding original.
    • 一种图像形成装置,包括:一个供给单元,用于将多个原稿顺序地馈送到曝光板;曝光单元,其可沿着曝光板移动,用于将原稿暴露在曝光板上;图像形成单元,用于在片材上形成 由曝光单元曝光的原稿上的图像,以及用于提供第一复印操作的控制单元,其中在曝光单元停止执行复印时原稿由馈送单元偏移,或第二复印操作 ,其中曝光单元被移动,而由馈送单元馈送的原稿在曝光板上停止。 当控制单元执行在第一复印操作之后执行第二复印操作的第一模式(例如,复印件> 1)时,馈送单元馈送原稿,同时保持先前原稿的前端和 并且其中,当所述控制单元执行仅执行所述第一复印操作的第二模式(例如,副本1)时,所述馈送单元馈送所述原稿,同时保持所述原稿的后端之间的第二恒定距离 的前一个原件和一个后续的原件的前端。
