The present invention relates to an automatic ice maker which is operated to supply ice iced through ice detection to the ice storage container upon completion of ice making. In general, the ice maker is generally driven by starting the normal rotation (CW) after the ice making operation is completed. Not only was it not easy to implement a cam structure or stopper capable of reverse rotation over a certain angle, but it was also difficult to predict the necessity at all.

However, it is not easy to separate the expanded ice in the ice-making container by only rotating the ice-making container according to the ice-making of the automatic ice-making machine, so to fix this, one side of the ice-making container is initially fixed and the other side is reversed to twist the ice-making container. This prevents freezing and separates the ice in the ice-making container before the ice-making operation.

In addition, by efficiently reconfiguring the arrangement between parts in the main body, it is possible to freely form the latching jaws of the detection lever and the counterclockwise stopper, and the stopper adheres to the case fixing shaft, and the shock and vibration are durable.
