The reversing conveyance mechanism 38 has a first reversing conveyance roller 31, and a first gear train 51 that transfers drive power from a reversing conveyance motor 39. A backlash part 70 enabling relative rotation in a preset angular range between the first final gear 64 and first reversing conveyance roller 31 is disposed between the first final gear 64 of the first gear train 51 and the first reversing conveyance roller 31.
