That is, the band-shaped print medium such as a label member often has a different size depending on the print content, and particularly when the pitch in the transfer direction of the label member is different, it corresponds to the type of each label member. It is necessary to change the cutting position. Moreover, it is important to protect the printed contents from the scanning process with an optical reader such as a pen scanner that will rub the printed surface when optically readable printing such as a bar code or other stains. It has become a process. Furthermore, it is special to make a single-leaf label by cutting the label member covered with the transparent strip film, including the mount, but cut the mount located at the bottom layer of the label member. However, when cutting only the strip-shaped film on the upper layer side, it is necessary to cut the strip-shaped film of interest by pressing it from the strip-shaped film side, and cut only the strip-shaped film or label member etc. It is also necessary to devise a cutting mechanism having a structure suitable for such a push-cut function, such as needing to cope with a cutting mode such as whether to cut the mount.
