Claims

[Scope of Claim for Utility Model Registration] (1) A loading table for loading a plurality of recording sheets, a calling roller that contacts the topmost sheet of recording sheets on the loading table and feeds the topmost sheet in the paper feeding direction, and a loading roller. A paper feeding device comprising: a pair of transport rollers that sandwich and transport the recording paper fed out in the paper feeding direction; and an exit guide plate that extends from the exit side of the mounting table to the nip portion of the pair of transport rollers. An exit guide plate is supported so as to be able to swing up and down around the nip portion of the pair of conveyance rollers, and the end of the exit guide plate on the loading table side changes depending on the change in the paper surface height of the recording paper on the loading table. A paper feeding device characterized by variable height. (2) An engaging portion that engages with the end of the exit guide plate on the mounting table side is provided on the vertically movable shaft supporting member that pivotally supports the calling roller, and this engaging portion allows the exit guide plate to be moved up and down. 2. The paper feeding device according to claim 1, wherein the height of the end on the mounting table side is variable. (3) The shaft support member consists of a rocking body which pivotally supports the calling roller at one end and is swingably supported by a support shaft at the other end, and a protrusion-like engagement formed at the middle part of the rocking body. 3. The paper feeding device according to claim 2, wherein the exit guide plate is biased by biasing means at the joint portion.
