In the present embodiment, each transfer unit 100 includes a first roller 110, a second roller 120, and a belt 130. The second roller 120 is spaced apart from the first roller 110 in the transport direction X, and the belt 130 is wound between the first roller 110 and the second roller 120. The belt 130 has a conveying surface 131 capable of conveying the object 200 from the first roller 110 to the second roller 120.

The second roller 120 of each transfer unit 100 is located above the first roller 110 of an adjacent downstream transfer unit 100, the second roller 120 of each transfer unit 100 at least partially overlaps with an orthographic projection of the first roller 110 of the adjacent downstream transfer unit 100 on a first plane parallel to the transfer direction X, and the diameter of the outer circumferential surface of the second roller 120 is smaller than that of the outer circumferential surface of the first roller 110.
