A triangular protrusion 96 is formed on one side of the triangular protrusion 96, 961, and a second arc-shaped inclined surface 962 is formed on the other side.

A portion of the discharge hole 95 to which the one end of the discharge hole 95 is connected is formed with a downwardly inclined surface 963.

Therefore, it is possible to guide the lens 100 to be conveyed at a higher speed by taking the downward slope 963.

The vibrator 44 generates vibration by supplying air.

Therefore, the vibration generated in the vibrator 44 is transmitted to the main body 3, which further amplifies the vibration of the supporter 92 made of the thin metal plate.

The operation of the alignment device thus constructed is as follows.
