2. Description of the Related Art Conventionally, in an automatic labeling device for sticking a label indicating a product name and content to an article such as an article, individual labels can be continuously peeled on a strip-shaped backing sheet at predetermined intervals. For each article that is pasted to the label and conveyed to the pasting position, the labels that have been peeled off one by one at the sharp backing of the mount at the label peeling edge are fed out as the mount moves, and the automatically peeled labels are It is known that the upper surface is continuously attached.

However, in the conventional structure as described above, labels having different sizes can be flexibly attached by using the same automatic labeling device, but the peeled labels are fed out. Unless the speed and the conveying speed of the article are accurately synchronized, the label cannot be accurately attached at a predetermined position on the upper surface of the article,
Therefore, each time a label with a different size is changed, a complicated preparatory work is required to finely adjust the feeding speed of the label one by one. It has the drawback of inducing a significant decrease in efficiency.
