Along the line, mark near the print head 7! A pressure body 9 hung on the printer base frame 8 to control the posture of the paper
A plate-shaped paper guide plate 2 has been provided that presses the paper to be written on the paper feed path structure such as the platen 1 by the spring force generated by the platen 1.

There are many methods that utilize the elasticity of the paper guide plate itself, with the aim of always generating a uniform and appropriate pressing force without the paper guide plate hitting the recording paper unevenly on the pressing surface, regardless of the paper type. It is used. In this case, in order to obtain an appropriate pressing force, a thin stainless steel plate, a plastic film, or the like is used as the material for the paper guide plate.

を押圧する事が不可能になるという課題を有していた。] Problems and Objectives to be Solved by the Invention 1 However, in conventional paper feeding devices, when a plate-shaped elastic body is used as a paper guide plate as described above, recording paper with high bending rigidity passes through the paper feeding path. When excessive displacement is applied in the opposite direction to the pressing direction due to paper jamming in the paper feeding path, or an artificial external force, the paper guide plate 2 may exceed the elastic deformation region. After that, there was a problem in that it became impossible to press the recording paper uniformly on the pressing surface.
そこで本発明は、従来のこの様な課題を解決するため、
紙ガイド板２に、押圧方向とは反対方向に過剰な外力が

生じることを防止し、常に均一で適正な押圧力を発生す
る紙送り装置を得ることを目的とする。Therefore, in order to solve these conventional problems, the present invention has the following features:
Even if an excessive external force acts on the paper guide plate 2 in the opposite direction to the pressing direction, plastic deformation such as bending or bending is prevented from occurring in the paper guide plate 2, and a uniform and appropriate pressing force is always generated. The purpose is to obtain a paper feeding device.

ことを特徴とする。Means for Solving the Problems 1 In order to solve the above problems, the paper feeding device of the present invention includes a rigid paper guide fixed to the printer frame on the back side of the recording paper pressing surface of the paper guide plate. It is characterized by having a plate regulating body.

働く外力は、紙ガイド規制体が受ける。[Function] In the paper feeding device of the printer configured as described above, the recording paper is pressed against the paper guide plate 2 due to the passage of recording paper with high bending rigidity, a paper jam in the paper feeding path, or an artificial external force. When an excessive external force is applied in the opposite direction, the paper guide plate will come into contact with the paper guide plate regulating body and work after the contact, even though the displacement of the paper guide plate or pressurizing body 9 will reach the plastic deformation region. The paper guide regulating body receives the external force.

ある。Therefore, plastic deformation such as bending or bending does not occur in the paper guide plate 2, so that the recording paper is always guided along the paper feeding path structure such as the platen 1 with a uniform pressing force. '1'' is possible.
