Recording apparatus

Abstract

There is provided a recording apparatus including: a hopper which is swingably installed on which paper sheets are placed; a feeding roller which is rotatably installed in a downstream side of the hopper in a feeding direction and feeds the recording media; a media guide surface which is opposed to an outer peripheral surface of the feeding roller with a gap therebetween; a separating roller which is installed in a downstream side of the media guide surface in the feeding direction and separates the paper sheets through cooperation with the feeding roller, in which the shortest distance between the outer peripheral surface of the feeding roller and the media guide surface in the gap becomes long along with the rotation of the feeding roller during one rotation of the feeding roller.

What is claimed is: 
     
         1 . A recording apparatus comprising:
 a hopper which is swingably installed on which recording media are placed;   a feeding roller which is rotatably installed in a downstream side of the hopper in a feeding direction and feeds the recording media;   a media guide surface which is opposed to an outer peripheral surface of the feeding roller with a gap therebetween;   a separating roller which is installed in a downstream side of the media guide surface in the feeding direction and separates the recording media through cooperation with the feeding roller; and   a recording unit which make a record on the recording media separated by the feeding roller and the separating roller,   wherein the shortest distance between the outer peripheral surface of the feeding roller and the media guide surface in the gap becomes long along with the rotation of the feeding roller during one rotation of the feeding roller.   
     
     
         2 . The recording apparatus according to  claim 1 ,
 wherein the feeding roller is configured to have a circular arc portion and a linear portion which make an approximately D shape from a side view,   wherein the outer peripheral surface viewed from a rotational axis of the feeding roller in an axis direction forms the circular arc portion, and   wherein the rotational axis is installed to be deviated from the center of the circular arc portion toward an opposite side to a starting end of the circular arc portion in the outer peripheral surface viewed from the feeding roller in the rotation direction.   
     
     
         3 . The recording apparatus according to  claim 2 ,
 wherein the outer peripheral surface viewed from the rotational axis of the feeding roller in the axis direction includes a first outer peripheral surface that forms a portion of the circular arc portion; and a second outer peripheral surface that is continuous from the first outer peripheral surface and has a distance between the center of the circular arc portion and the second outer peripheral surface which becomes shorter as the second outer peripheral surface is located further on a finishing end side that opposes the media guide surface later than the starting end.
