An automatic hair implanter is capable of continuously performing hair transplantation work by applying a structure of a conventional manual hair implanter. The automatic hair implanter (hair transplantation device) comprises a rotating magazine therein, and several needle modules are stored in the magazine. Two pushrods, which are positioned on a rear portion of the device and capable of translational motion, play a role of pushing a needle and a shaft, which constitute a needle module, forward. The needle and the shaft may be moved backward by a spring positioned inside the magazine.
