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.
