The infrared sensor 585 is arranged on the positioning plate 53, the horizontal position of the infrared sensor 585 is slightly lower than the feeding hole 512, when paper is stacked and blocks the infrared sensor 585, the infrared sensor 585 sends out a signal, and the fourth driving motor 584 works to drive the bottom plate 52 to move downwards. When the infrared ray sensor 585 is not shielded by the paper sheet, the fourth driving motor 584 is stopped.

Further, in order to make the bottom plate 52 more stable in the up-down lifting process, the guide posts 586 are vertically fixed at the four corners of the support 51, the four corners of the bottom plate 52 are respectively sleeved on the guide posts 586, and the bottom plate 52 slides up and down along the guide posts 586, so that the paper thereon is relatively stable.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
