An apparatus for lifting a sheet from a stack of sheets including a frame, a suction plate for engaging a sheet from the stack, a lifter connected to the suction plate so as to move the suction plate in a vertical direction, a setting member pivotally connected to the suction plate, and a ramp member connected to the frame and positioned along a length of the setting member. The lifter serves to move the suction plate between a first sheet-engaging position and a second sheet-releasing position. The suction plate is pivotally connected to the lifter so as to align parallel to the surface of a sheet. The setting member extends upwardly from the suction plate The ramp member is in cooperative relationship with the setting member. The setting member causes the ramp member to be positioned in parallel relationship to the suction plate when the suction plate is in the first position. The ramp member is stationary during a movement of the suction plate between the first and second positions. The suction plate includes a plate carrier and a setting member pivotally affixed to a surface of the plate carrier. The setting member extends through an opening in the ramp member. An abutment member is affixed to the setting member so as to be interactive with the ramp member.
