Apparatus to control the operation of corner separator members operating to separate individual sheets from the top of the stack as they are depleted. A pair of sheet separator members positioned at the stack corners resist the movement of the sheets to force only the topmost sheets to buckle thereover and be fed therepast. The separator members, each mounted on an arm, move in a generally vertical path as the sheets are fed from the top of the stack. As the stack height decreases a biasing action enables pivotal movement of the separator member on the arm as contact is made with the stack edge near the bottom. A camming mechanism serves to raise the arm and separator member upwardly upon insertion of a new stack by mechanical actuation or an electrical signal.
