    • A skew feed or damage in the sheet in automatic feeding is avoided. In an image forming apparatus provided with a printer for recording an image, the printer is provided with a feeding port for enabling manual insert sheet feeding and an automatic sheet feeder (ASF) is detachably mounted on the feeding port to enable automatic sheet feeding through the feeding port. As shown in the drawings, the printer is provided with a printer sheet guide for manual insert sheet feeding, while the ASF is provided with an ASF sheet guide for automatic sheet feeding, and the ASF sheet guide is displaced toward the inner side of the sheet by a predetermined amount with respect to the printer sheet guide. Thus, the sheet automatically fed utilizing the ASF sheet guide does not contact the printer sheet guide, whereby the skew feed of the sheet and the damage to the sheet end can be prevented.
    • 避免了自动进纸中的纸张偏斜进给或损坏。 在设置有用于记录图像的打印机的图像形成装置中,打印机设置有用于使手动进纸输送的进给端口,并且自动进纸器(ASF)可拆卸地安装在进给口上,以使得能够通过 进料口。 如图所示,打印机设置有用于手动进纸的打印机纸张引导件,而ASF设置有用于自动进纸的ASF纸张引导件,并且ASF纸张引导件朝向纸张的内侧移位 相对于打印机纸张引导件预定量。 因此,利用ASF片材引导件自动进给的片材不接触打印机片材引导件,从而可以防止片材的歪斜进给和片材端部的损坏。
