AI Technical Summary

Problems solved by technology

Since the above-mentioned blade parts are opened halfway, when the 3-inch paper reel is placed, slippage may occur between the above-mentioned reel support and the 3-inch reel, resulting in paper slack
At this time, it is possible that the slack of the paper cannot be controlled
[0010] In addition, in the state where the above-mentioned blade parts are closed halfway, if a 2-inch paper reel is to be placed, the above-mentioned blade parts may be caught on the reel and cannot be put in.
