片材处理装置及具备它的图像形成装置
摘要：
一种片材处理装置，所述片材处理装置具备运入路径、位移辊、运入辊和冲孔移动单元，所述运入路径对来自运入口的片材进行引导，所述位移辊被设置在此运入路径上，运送片材并且位移，所述运入辊位于此位移辊的下游侧，将来自上述运入路径的片材朝向上述集聚托盘运入，所述冲孔移动单元被设置在此运入辊的上游侧，在处理位置对片材的端部进行处理，其中，通过冲孔移动单元在与位移辊相同的方向进行位移移动，并且将冲孔移动单元的位移量设定得与位移辊的位移量相等或比它大，在片材位移后，端部处理单元已位于端部处理位置或与之接近的位置，因此，能缩短片材的位移和端部处理的处理时间。
摘要（英）：

A sheet processing apparatus is provided with a carry-in path for guiding a sheet from a carry-in entrance, a shift roller provided in the carry-in path to transport the sheet, while shifting, a carry-in roller positioned on the downstream side of the shift roller to carry the sheet from the carry-in path toward a collection tray, and a punch shift unit provided on the upstream side of the carry-in roller to process an end portion of the sheet in a processing position. The punch shift unit shifts in the same direction as the shift roller, a shift amount of the punch shift unit is set to be equal to a shift amount of the shift roller or more, and the end portion processing unit is thereby already positioned in an end portion processing position or a position near the processing position after shifting the sheet. Displacement of the sheet and processing time of end portion processing are reduced.
