゛1 Alternatively, you can directly put a large amount of seeds in a flat shape into a seedling raising container and let them germinate and entangle the roots, or you can put a small amount of seedling base material such as soil into a seedling raising container and make a mat-like seedling that has sprouted. This invention relates to a transplant device that divides and transplants bacteria into individual strains.

(Prior Art) A conventional transplant device is operated by a crank and a swinging rod as seen in Japanese Utility Model Publication No. 49-28734. This device has a structure in which the seedlings are divided and transplanted, and even if the rotation of the transplanting tool is increased significantly, the rotation speed is limited to 300 to 350 rotations per minute, making it impossible to transplant at high speed. For this reason, in order to enable high-speed transplantation, an attempt was made to take technical measures to attach two or three transplant tools to a rotating case, as seen in Japanese Patent Publication No. 17806/1983, but the above-mentioned It is difficult to think of a technical means in which the transplanting device as shown in Japanese Patent Publication No. 49-28734, that is, the seedling release operating mechanism, can be placed inside the transplant case as it is, and the technology disclosed in Japanese Patent Publication No. 49-17806 cannot be put into practical use. There wasn't. In other words, it has not been possible to develop a technique for equipping the transplant case with a cam body for the 1°I''i release actuation mechanism.
