いて発生する騒音が大幅に低減される。Here, the recording paper 5 that has entered the recording paper conveyance guide body 13 and is conveyed along the conveyance path 14 makes noise by contacting the inner peripheral surface of the recording paper conveyance guide body 13. However, since the recording paper conveyance guide body 13 is formed in a box shape having openings 15 and 16 only in two places and the other portions are closed, noise generated in the recording paper conveyance guide body 13 is not generated. It is attenuated in the recording paper conveyance guide body 13 by the enclosure effect, and the openings 15, 1
The noise leaked from 6 becomes small. Therefore, the noise generated at the time of sheet feeding is significantly reduced.

ができる等の効果を有する。As described above, according to the first aspect of the present invention, the separation sheet feeding section for separating and feeding the recording sheets one by one and the recording sheet fed from the separation sheet feeding section are set in a predetermined manner. In a paper feeding device having a registration roller that feeds to a recording unit at a timing, the recording paper enters and leaves only between the separation paper feeding unit and the registration roller, and a portion facing the registration roller and the separation paper feeding unit. Since the box-shaped recording paper conveyance guide body having the opening portion is provided, the recording paper conveyance guide body for conveying the recording paper fed from the separation paper feeding unit to the registration roller has only a pair of openings. Since the other parts are closed, the noise generated when this recording paper comes into contact with the inner peripheral surface of the recording paper conveyance guide body is attenuated in the recording paper conveyance guide body due to the enclosure effect and leaks out from the opening. It becomes significantly small things to, therefore, has an effect such as can be significantly reduce the generation of noise at the time of paper feeding.
