Title: Sheet feed cassette

Abstract: A sheet feed cassette includes a tray having a pair of corner claws which assume a raised position in the non-feed position of the tray and which move down from the raised position when the tray is placed in its feed position. A receptacle is provided for slidably supporting the sheet tray, and includes a guide member having formed therewith notches which are located opposite to the corner claws. The corner claws have projections which are guided by the guide member, thereby controlling the vertical movement of the corner claws in dependence upon the relative position between the projections and the guide member.
