Pick-up device

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;
• and
• a holding mechanism that holds the first workpiece from the top, the holding mechanism includes a gripping member that is lowered relative to a claw member on an upper side of the claw member to grip the first workpiece, and a gripping drive unit that gives the gripping member a movement operation for allowing the gripping member to move along a relatively downward direction with respect to the claw member,
• wherein the pick-up nozzle includes a ventilation groove provided on a bottom surface opposite to an upper surface of the first workpiece from the top and passing through to an air blowing side end part of the bottom surface, and a nozzle port blowing air toward the air blowing side end part of the bottom surface along the inside of the ventilation groove,
• the air blowing side end part of a groove inner bottom surface of the ventilation groove is formed in a shape directed in a direction of being separated from the workpiece, and
• the air blowing side end part of the bottom surface of the pick-up nozzle is separated from the first workpiece further than other portions of the bottom surface by a step.
