修正することができる。 The operation of the paper feeding device of this embodiment configured as described above will be described below. First, printing paper is inserted through the insertion portion 13b of the paper guide 13 and wound around the platen 1. At this time, if the printing paper is twisted and wound, when the paper press release lever 7 is rotated in the direction of the arrow AB, the dowel portion 11d of the support angle 11 is pushed by the cam portion 7a and rotates in the direction of the arrow. When the support angle 11 rotates, the paper pressing roller 8 is pushed vertically downward via the holding plate 9. In this state, the printing paper held between the platen 1 and the paper pressing roller 8 is released, so that the distortion of the printing paper can be freely corrected.

なる。 As described above, according to this embodiment, the support angle 11 is made into an integral body that pivotally supports the pair of holding plates 9, and the machine frame 6 is provided with the slit hole portion 6a that serves as a pivot point for the support angle. Since the support angle 11 is configured to be pushed directly by the paper presser release lever 7, the number of support angles is reduced from two to one compared to conventional paper feeding devices, and the rotation axis of the support angle is eliminated. The drive member and its support shaft for pushing down the angle are also eliminated. Therefore, the structure is simple, the number of parts is small, and it is possible to achieve a reduction in size and weight.
