<P>PROBLEM TO BE SOLVED: To provide a workpiece stocker capable of feeding a rear workpiece to the front to surely move the workpiece to the front, when a front workpiece is taken out. Ž<P>SOLUTION: The workpiece stocker is equipped with a ramp 5 with its rear end supported higher than its front end and with stoppers S<SB>1</SB>-S<SB>m</SB>arranged along the ramp 5 at predetermined intervals. The stoppers S<SB>m</SB>(m is all the integers not less than 2 and not more than the total number of the stoppers) is composed of a workpiece detection arm 6 and a workpiece locking arm 7. When the workpiece detection arm 6 of the stopper S<SB>m</SB>detects that a workpiece W is locked by the last stopper S<SB>m-1</SB>, the workpiece locking arm 7 of the stopper S<SB>m</SB>stands backward to lock the following workpiece W. When the workpiece detection arm 6 of the stopper S<SB>m</SB>does not detect that the workpiece W is locked by the last stopper S<SB>m-1</SB>, the workpiece locking arm 7 of the stopper S<SB>m</SB>is brought down forward to let the following workpiece W pass.
