Abstract

PURPOSE:To set recording paper easily while preventing the displacement of line pitches by rotatably mounting an arm supporting rolled recording paper to a device proper within a fixed angle. CONSTITUTION:When a shaft 9 is passed into the hole of rolled recording paper 7 and placed in grooves 10c in an arm 10, the arm 10 is turned in a case 8, and side plates 10b are brought into contact with projections 8b and stopped. The front end of recording paper 7 is inserted among paper-feed rollers 2 and a paper guide section 10a from upper and lower sections, guided to the paper-feed rollers 2 by paper guide members 10e, and wound on the paper-feed rollers 2, and recording paper 7 is forwarded upward from a section between a printing head 4 and a platen 3. When the rollers 2 are rotated and recording paper is fed only by one line, the paper guide section 10a is pushed downward by the inertia of the rolling section of recording paper 7. The paper guide section 10a is pushed upward owing to the weight of the rolling section immediately after the paper guide section 10a is pushed downward, and the rolling section is turned and the state of the waiting for the next line-feed is brought about. Accordingly, the displacement of line pitches due to the inertia of the rolling section can be prevented.

However, in the conventional configuration described above, when setting the recording paper 7, if the space between the roll portion 7a of the recording paper 7 and the paper feed roller 2 is narrow, the recording paper 7 Connect the edges of case 1 and paper feed roller 2.
It is difficult to insert recording paper 7 between cases 1 and 1.
Before placing the recording paper 7 on the paper, insert the end of the recording paper 7 between the case 1 and the paper feed roller 2, rotate the paper feed roller 2 to wrap the recording paper 7 around the paper feed roller 2, and then It has to be placed in the case 1, and since the insertion position is exposed to the back side of the paper feed roller 2 and platen 3 to the operator, when setting the recording paper 7, the operator has to look into the insertion slot, which is very inconvenient. Furthermore, if the roll diameter of the recording paper 7 is large and heavy, the inertia of the roll portion 71a of the recording paper 7 may prevent sufficient paper feeding due to sudden line feeding, resulting in deviations in the line pitch. It had some problems.
