[0043] After the proximity sensor 301 senses the metal tooth sheet 220, the linear vibrator 200 stops vibrating. The rotating mechanism 330 with an internal magnet attracts the metal tooth sheet 220 and starts to rotate. The fiber optic sensor 302 senses the correct angle of the metal tooth sheet 220, and the rotating mechanism 330 stops rotating.

The transfer mechanism 400 runs to the material placing position above the fine positioning table 500. The up-and-down air cylinder 420 extends to the material placing position.
