Abstract:
1. An apparatus, comprising: a sheet container tray, in which sheets can be stored; and a guide member, which is arranged to be movable on a bottom of the sheet container tray along a movable direction and is configured to restrict a position of edges of the sheets, wherein the sheet container tray includes a plurality of first engagement sections, which is provided in a plurality of positions corresponding to a plurality of sizes for the sheets; wherein the guide member includes an arm part, which extends longitudinally along the movable direction of the guide member at the bottom of the sheet container tray and is configured to be rotatable in a plane parallel to the bottom of the sheet container tray about a basal end portion of the arm part, and a first engageable part, which is configured to be engageable with the first engagement sections; wherein one of the plurality of first engagement sections and the first engageable part is formed to have a concave structure, and the other one of the plurality of first engagement sections and the first engageable part is formed to have a convex structure; wherein a first plane in the concave structure, which becomes slidably in contact with the convex structure when the guide member is moved in a pointing direction pointed by a longitudinal tip end of the arm part at the bottom of the sheet container tray, is formed to incline in a more moderate angle with reference to the movable direction of the guide member than an angle of a second plane in the concave structure, which becomes separated from the convex structure when the guide member is moved in the pointing direction; wherein the sheet container tray includes a plurality of second engagement sections, which is provided in a plurality of positions at smaller intervals than intervals between the first engagement sections; wherein the guide member includes a manipulation member; wherein the manipulation member includes the arm part, the first engageable part, a manipulation part to be manipulated by a user, a second engageable part configured to be engageable with the second engagement sections, and an urging part configured to urge the second engageable part against the second engagement sections; and wherein the second engageable part is separated from the second engagement sections when the manipulation part is manipulated against urging force from the urging part.
