していた。In the above configuration, in order to feed the recording paper smoothly, it is necessary to press the paper feeding roller against the platen roller with uniform pressure. However, when the width of the recording paper is wide, it is necessary to increase the length of the platen roller, and it is difficult to manufacture the platen roller with a uniform outer diameter. Therefore, in order to absorb the non-uniformity of the outer diameter of the roller, the paper feed roller 1 is generally divided into several parts and each part is applied to the platen roller independently, as shown in Fig. 4. used, but still
As shown in FIG.
There is a problem that the contact of the paper feed reroller 1 is not uniform, and there is a drawback that precision is required in manufacturing the paper feed section.

定されている。In FIG. 6, a gap 13 is formed in the through hole of the holder shaft 8 provided in the roller holder 3, and the overall shape of the through hole 8 is a ``'' shape (drum shape) in which the central part of the hole is constricted. From the position where the paper feed roller 1 is in contact with the platen roller 6, it can further rotate in the direction of arrow C. In addition, when the holder shaft 4 whose stepped surface has an elliptical shape is rotated to the position shown in FIG. The dimensions are set such that the fixation of the paper 7 can be released.
