印字しなければならないという問題点があった。However, in the above-mentioned prior art, when the paper is slanted at the time of feeding,
There was a problem that it had to be replaced.
In addition, when using continuous paper, even if the paper is slightly inclined, the position of the paper will gradually shift while it is being fed. There was a problem that it had to be used. Further, since the cylindrical roller is used, there is a problem that the width of the roller limits the width of usable paper. Further, when printing diagonal characters on paper, there is a problem in that the character data must be processed diagonally on software and then printed.

る。Therefore, the present invention solves these problems, and an object of the present invention is to have a mechanism capable of compensating for a skewed sheet at the time of sheet feeding or continuous sheet use. Is. Also, due to the spherical roller,
Since the paper can be freely moved not only in one direction but also in two directions (xy directions), it is possible to eliminate the limitation on the paper size. Furthermore, since the paper can be freely rotated,
It is possible to easily print characters at any angle.

る。By using two (or more, if necessary) spherical rollers in the paper feeding mechanism portion, by making a difference in the rotation speed of each roller when the paper becomes oblique, Correct the damaged paper.
【０００８】また，ローラーの回転方向を制御する事に
よって，自由な角度で自由な位置に紙を送る事が出来
る。Further, by controlling the rotating direction of the roller, the paper can be fed to a free position at a free angle.

字することが可能となる。FIG. 1 shows an embodiment in which a single-cut sheet is used, and the printing paper 1 can be freely moved in the vertical and horizontal directions by two spherical rollers 1. Further, by making the rotational speeds of the two spherical rollers 1 different, the printing paper 1 can be rotated at any angle. This is because it is possible to intentionally change the angle of the printing paper 1 for printing characters diagonally, and at the same time detect that the printing paper 1 is skewed by force majeure and restore it to the original angle. It is also possible. Further, when printing on a large size printing paper 1, the paper winding mechanism 5
By providing the printer in the printer, it is possible to print without limiting the paper size.

ラクタユニットが必要なくなる。FIG. 2 shows an embodiment in which continuous paper is used. The difference from the structure of a conventional printer is that the spherical roller of the present invention is used as a paper feeding mechanism and that a tractor unit is not provided. . When printing on continuous paper 4,
The print position gradually shifts. When the positional deviation is detected, the rotational speeds of the two spherical rollers 1 are made different to correct the original position. Therefore, by using the spherical roller 1 of the present invention, a tractor unit is unnecessary.

刷可能である。As described above, according to the present invention, by using the spherical roller in the paper feeding mechanism portion of the printing apparatus, it is not necessary to reset the paper even if the paper is slanted at the time of paper feeding. In addition, continuous paper can be printed without a tractor unit.
【００１３】また，紙の角度を自由に変えたり，紙送り
方向を自由に変える事が出来る為，自由なサイズに紙に
自由な角度で文字を印刷する事が出来る。Further, since the angle of the paper can be freely changed and the paper feeding direction can be freely changed, it is possible to print characters on the paper in any size and at any angle.
