When a sheet containing portion is attached to an accommodating portion, a drawing-in member which is rotatably provided on an accommodating portion is engaged with a locking member which is turnably provided on the sheet containing portion and in this state, the drawing-in member is rotated. With this, the locking member is turned and the sheet containing portion is drawn into the accommodating portion. The guide member is provided with a guide portion and an introduction opening. When the sheet containing portion is attached, the locking member is introduced to the guide portion from the introduction opening. A forming range of the introduction opening in a direction intersecting with an attaching direction of the sheet containing portion is set equal to or smaller than a forming range of the guide portion in a direction intersecting with the attaching direction of the sheet containing portion.
