It has as a placement surface. The first belt conveyor 16 is arranged on the object to be conveyed portion 14 by moving the object to be conveyed 121 together with the first transfer belt 161 in the first transfer direction D1c in a state where the object to be conveyed 121 is placed on the upper surface 161a of the first belt. The target object to be transported 121 is separated from the object to be transported at the second position 122. Then, the first belt conveyor 16 conveys the target object to be conveyed 121 in the first transfer direction D1c while separating the object to be conveyed at the second position from the object to be conveyed 122.

At the time of the transportation, the object to be transported 121 is transported while being maintained in a predetermined posture in a predetermined section on the first transport belt 161. Specifically, the predetermined posture is a posture in which the object to be transported 121 extends in the axial direction D1a of the first pulleys 162 and 163 to form a flat shape along the upper surface 161a of the first belt.

To achieve the above, the first belt conveyor 16 has a plurality of first projecting portions 164 formed so as to protrude from the upper surface 161a of the first belt and fixed to the first transport belt 161.
