So set up, the circular arc section operation at hold-in range 14 of card carrier 151 of being convenient for realizes the cyclic motion of card.

The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present patent application are included in the protection scope of the present patent application.
