2. Description of the Related Art Generally, a printer of this type is provided with a printing section for printing required transaction information and a cutting section for cutting the printed sheet into a predetermined size on a running line of printer paper. Etc. are issued.

However, while the printing section and the cutting section are efficiently and compactly arranged on the running line, paper jam easily occurs, and when the paper jam occurs, the supplied paper continues. As a result, paper jams occur, causing dot breakage of the print heads located in the vicinity of the paper jams, and it has become difficult to remove paper in narrow paper jam areas.

Further, since the cutting portion fixed by screws is located in the vicinity of the attaching / detaching portion of the ribbon cassette, it is difficult to attach / detach, and in the case of a weak paper, the printing portion and the cutting portion are located intensively in the traveling. There was a problem that it was difficult to insert into the line part and the initial setting was difficult.

As a means for solving these problems, as disclosed in Japanese Patent Laid-Open No. 58-3889, a sheet is run on the movable blade side out of the fixed blade and the movable blade which constitute the cutting device. It can be configured to rotate away from the line. However, even with such a configuration, there is a problem that the relative positional relationship between the fixed blade and the movable blade shifts, the meshing of the blades deteriorates, and cutting failure occurs.
