  • Publication number: 20220297963
    Abstract: A sheet feeding device feeds a sheet in a feed direction. The sheet feeding device includes a loading portion, a feeler, and a first detection sensor. The sheet is to be placed on the loading portion. The feeler rotates from a reference position to a pushed position around a support shaft in response to a push by a downstream end of the sheet, which is placed on the loading portion, in the feeding direction. The first detection sensor detects a rotation of the feeler from one of the reference position and the pushed position to the other of the reference position and the pushed position. The loading portion includes a second detection sensor to detect a state in which the sheet is placed on the loading portion.

  • Patent number: 11447354
    Abstract: A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.
