    • A sheet detecting apparatus including: a sheet detecting member having a plurality of abutment surfaces in a peripheral direction thereof, the sheet detecting member being rotated by a conveyed sheet abutting against one of the plurality of abutment surfaces; a detection portion which operates in association with the sheet detecting member; a sensor which generates a signal based on a position of the detection portion; and an urging portion which generates an urging force for positioning the one of the plurality of abutment surfaces of the sheet detecting member in a waiting position in which the leading edge of a sheet conveyed by a conveying portion abuts against the one of the plurality of abutment surfaces, and thereafter the urging portion switching the urging force to an urging force for positioning, in the waiting position, another one of the plurality of abutment surfaces against which a succeeding sheet abuts.
    • 一种片材检测装置,包括:片材检测部件,其周向具有多个邻接表面,片材检测部件被抵靠在多个邻接表面中的一个的传送片材旋转; 检测部,其与片材检测部件相关联地操作; 传感器,其基于所述检测部的位置生成信号; 以及施力部,其产生用于将片材检测部件的多个抵接面中的一个定位的等待位置,其中由输送部件输送的片材的前缘抵靠在多个抵接部 并且此后,所述推动部分将所述推动力切换到用于在所述等待位置中定位另一个所述多个邻接表面中的另一个抵靠表面的推动力,所述多个邻接表面中的另一个邻接表面邻接。

    • A printer includes a fixing device that fixes a toner image formed on a sheet and a sheet delivery roller pair for delivering the sheet on which the toner image is fixed by the fixing device onto a sheet delivery tray placed outside of a printer main body. The printer includes a supporting member that supports an upstream edge portion of the sheet in a delivery direction delivered from the sheet delivery roller pair so that the upstream edge portion does not fall down on the sheet delivery tray. The printer includes a blower unit that blows air along a lower surface of the sheet supported by the supporting member from the upstream edge portion of the sheet in the delivery direction toward a downstream edge portion of the sheet in the delivery direction.
    • 打印机包括:固定装置,其固定形成在片材上的调色剂图像和片材输送辊对,用于将通过定影装置固定调色剂图像的片材输送到位于打印机主体外部的片材输送盘上。 打印机包括支撑构件,该支撑构件在从片材输送辊对输送的输送方向上支撑片材的上游边缘部分,使得上游边缘部分不会落在片材输送托盘上。 打印机包括鼓风机单元,其沿着沿着输送方向的片材的上游边缘部分沿着沿着输送方向的片材的下游边缘部分沿着由支撑构件支撑的片材的下表面吹送空气。
