Publication number: 20230159291Abstract: A sheet feeding apparatus includes a stacking unit including a plate, a feeding unit including a roller, a holder including a detected member, a drive unit and a controller. The detected member is positioned in a first position where the detected member is not detected by a detector in a case that the feeding unit is new, and is moved from the first position to a second position where the detected member is projected so as to be detected by the detector when the new feeding unit is mounted on the holder and the roller is driven. The controller controls the drive unit to perform up-and-down operation of the plate so that the plate is set to a feedable state of the sheet in a case that the feeding unit is mounted, and determines whether or not the feeding unit is new based on a detection result of the detector.Type: ApplicationFiled: November 16, 2022Publication date: May 25, 2023Inventors: Masato Suzuki, Kenichirou Isobe, Eiji Wakiyama, Takashi Yano, Hidehiro Ushiozu
