Claims

[Scope of utility model registration request]

In a media width adjusting mechanism that moves the media to a reference surface and aligns the media by sandwiching and transporting the media with a feed roller and a pressure roller, a link 2 is provided to be reciprocatable by a drive source 1 such as a magnet.
A lever 11 guided by this link 2, having a spring 14 between it and fixed to the rotating shaft 6, engages with the link 2,
A lever 15 is rotatably supported on a fixed stud 15a, a limiter 7 is engaged with the lever 15 and is freely rotatable with respect to the rotation shaft 6, and a limiter 7 is engaged with one end of the limiter 7 and is rotatable with respect to the rotation shaft 6. A pressure roller bracket 4a is pivotably supported on a shaft 5 mounted on a shaft 6 and is rotatable by a spring 8, and is rotatable together with the rotating shaft 6; and a pressure roller 4 rotatably supported by the bracket 4a.
a drive source 1 such as the magnet, etc.;
By energizing the link 2 and moving the link 2, the pressure roller bracket 4a rotates and the pressure roller 4 clamps the medium.
A media width shifting mechanism characterized by rotating to pull the media toward a reference surface 9 for alignment.
