ABSTRACT:
In accordance with the present invention an automatic paper roll loading mechanism intentionally produces a slack on the surface of a paper roll, indirectly senses the leading edge of the paper of the roller via the slack, and conveys the leading edge to a preselected stand-by position. The mechanism is therefore capable of automatically paying out the paper even when a mark is absent at the leading edge. This allows not only a fresh paper roll but also a half-used paper roll to be automatically loaded.
