Further, in this embodiment, the chute 63 of the workpiece separation chute section E is held in a horizontal state to receive the workpiece, and air is blown toward the workpiece from the air blowing hole 64 to float the workpiece and tilt the chute 63. Since the workpiece is conveyed by using the machine, the workpiece can be conveyed without damaging the workpiece.

Furthermore, in this embodiment, the workpieces are stored in the cassette 2 in the case of the workpiece stock case part, and the workpiece storage case part F stores the cassette 79 in the case, and the workpieces are stored in the cassette 2. Since the workpieces are taken out, it is possible to speed up the work of storing the workpieces to be processed and the work of taking out the processed workpieces.
