<P>PROBLEM TO BE SOLVED: To provide a path variable mechanism which satisfactorily removes the generation of transitional tension of roll-type printing paper and permits preferable printing by absorbing fluctuation of a paper length of the roll-type printing paper as continuous paper during the printing operation as a prescribed processing, and to provide a printer device comprising the path variable mechanism. Ž<P>SOLUTION: The path variable mechanism 200 has a path specification part 201 comprising: a paper roll grip roller 6 and a paper roll pinch roller 7 which specifies one end of a partial path at a fixed position; and a paper guide 1 which swings by making the other end of the partial path a fulcrum in accordance with the paper length of the roll-type printing paper 8 as continuous paper and changes the length of the partial path.
