1. A pick-up device picking up stacked sheet-shaped workpieces from the top, the device comprising:
a nozzle mechanism that includes a pick-up nozzle pulling up a first workpiece from the top of the stacked workpieces by air blowing;
a holding mechanism that holds the first workpiece from the top;
a separation mechanism that includes a claw member being inserted into a lower side of the first workpiece from the top with respect to the stacked workpieces, and a forward and backward drive unit causing a tip part of the claw member to move forward and backward;
a suction mechanism that includes a non-absorption type suction pad pulling up the first workpiece from the top of the stacked workpieces;
a control device that controls the nozzle mechanism, the separation mechanism, the suction mechanism, and the holding mechanism; and
a selection unit that selects one or more combinations of the nozzle mechanism, the separation mechanism, and the suction mechanism,
wherein the control device executes operation control for picking up the stacked workpieces from the top according to the selection of the selection unit.
