An elliptical turntable 41e for carrying the receiver 44 is formed.

As shown in FIG. 8, when a gap is provided between adjacent seedling supply cups 40 having a maximum diameter of 105 mm in the horizontal direction, a chain pitch of connecting and transporting each seedling supply cup unit of at least 127 mm is required. Therefore, the size of the turntable 41e of the transport type by the chain 43 becomes large as a whole. In this case, the number of links is required to be 10 on the basis of the case of transporting along a linear trajectory. However, when the arc-shaped turntable 41e shown in FIG. 7 is used, the chain pitch can be improved to 8 links. Thus, the seedling supply device 4
If a is a circular turntable 41e in plan view, the chain pitch (the number of links) is shorter than the diameter of the seedling supply cup 40, and the size of the chain transport type turntable 41e can be reduced as a whole.
