  • Publication number: 20230059834
    Abstract: A cassette portion includes a side guide, an end guide, and a paper detection portion. The side guide is movable in X direction and controls a motion of a first end portion of paper. The end guide is provided to the side guide to be movable in Y direction, and restricts a motion of a second end portion of the paper. The paper detection portion detects the first restricting position in the X direction of the side guide and a second restricting position in the Y direction of the end guide in a restricted state of the paper. The end guide includes a detection target portion formed such that detection information to be detected by the paper detection portion varies in the Y direction. The paper detection portion detects the first restricting position and the second restricting position by obtaining detection information from the detection target portion.
