Claims

[Scope of Claim for Utility Model Registration] (1) The paper is disposed in the paper feeding section of an image forming apparatus, etc., and the paper carried out from the paper tray by a nudger roller is subjected to a sorting action via a paper sorting mechanism, and the paper is separated into one piece. In an apparatus configured to feed sheets one by one, an auxiliary plate for pressing the paper against the feed roller is disposed downstream of a nip portion formed by a feed roller and a sorting roller of the paper handling mechanism, and the auxiliary plate is pressed against the feed roller. A tip connecting piece is arranged at the tip of the pressing piece to connect the pressing pieces on both sides, and the tip connecting piece connects the rollers between the two rollers. A paper feeding device characterized in that it is configured to be able to support nipped paper. (2) A paper handling mechanism configured such that a feed roller and a handling roller are arranged facing each other, the handling roller is driven in a direction opposite to the rotating direction of the feed roller, and paper handling is performed between the two rollers. A paper feeding device characterized in that the sorting roller is configured as a roller member having the same hardness as the feed roller. (3) A hard core member is installed on the shaft of the sorting roller,
A paper feeding device according to claim 2 of the utility model registration claim, characterized in that a soft coating is formed on the outer periphery of the core member so that the apparent hardness of the roller member matches that of the feed roller. . (4) Arranged in a paper feeding section of an image forming apparatus, etc., the paper is separated from the paper tray by a nudger roller through a paper separation mechanism, and the paper is fed one by one. In this apparatus, an auxiliary plate for pressing the paper against the feed roller is disposed downstream of the nip between the feed roller and the sorting roller of the paper handling mechanism, and the auxiliary plate is connected to the presser plate arranged on both sides of the roller. The sheet handling mechanism is configured with a separating roller having the same hardness as the feed roller. Characteristic paper feeding device.
