To provide a pin collecting mechanism collecting pins at high speed.

A shaped slit 121 provided on a fixed plate 120 has a first slit part 121A inside the slit 121 in a receding side of a rotation, having a minor axis size A larger than a diameter of a smaller-drum part P1 of a pin P and smaller than a diameter of a larger-drum part P2 of the pin P and a second slit part 121B inside the slit 121 in an advancing side of the rotation, having a minor axis size B larger than the diameter of the larger-drum part P2 of the pin P. Thereby while the pin P is not reversed in a transfer direction, the pin P can be rotated to be arranged in the same direction, enabling pin P collecting speed to be high without decreasing a pin P collecting rate.
