Only the workpiece W in the reverse direction can be inverted in the rotary chute 131 by detecting as a reference, and thus only the workpiece W in the forward direction can be injected into the machining side of the automatic processing machine 300.

That is, as shown in Figure 5, when the workpiece (W) loaded on the stocker 210 is randomly raised to the input side of the fixed chute 111 inclined at an angle by the chain conveyor 220, it is not selected. The workpiece W is not moved in the oblique direction. At this time, the tip pin 114b of the first cylinder member 114 mounted vertically on the upper side of the fixing chute 111 is in a raised state, while the tip pin 115b of the second cylinder member 115 is raised. Since it is in the lowered state, the supplied work W no longer moves in the cloud, and stops and stays in the middle of the fixed chute 111. At the same time, the tip pin 114b of the first cylinder member 114 is lowered in response to the detection signal of the presence / absence sensor member 121 to confirm the presence or absence of the workpiece W.
