FIG. 1 is an explanatory diagram showing the main parts of an embodiment of the paper feeding device of the present invention, FIG. 2 is an explanatory diagram showing the deviation of the image forming position that occurs in the paper feeding device of the present invention, and FIG.
The figure is a schematic configuration diagram of a conventional paper feeding device. Figure 4 shows that when the axial length of the paper feeding roller and reverse roller is the same, a deviation occurs in the axial position of both due to axial play. Figures 5a and 5b are front views and plan views showing the state in which recording paper is conveyed while being nipped by rollers that are misaligned in the axial direction. FIG. 6 is a diagram showing the degree of skew and the number of sheets generated corresponding to each skew value when one sheet is conveyed to the nip between the paper feed roller and the reverse roller and when two or more sheets are conveyed in duplicate. 1...Recording paper, 2...Bottom plate, 3...Arm, 4

Claims (1)
搬送する給紙コロ及びリバースコロを有した給紙
装置において、 該給紙コロの軸方向長さを該リバースコロの軸
方向長さよりも大きく設定してリバースコロの端
部の軸方向への突出を防止した給紙装置。[Scope of Claim for Utility Model Registration] In a paper feeding device having a paper feed roller and a reverse roller that separate and transport conveyed recording paper at a nip portion, the axial length of the paper feed roller is defined as the axis of the reverse roller. A paper feeding device that prevents the end of the reverse roller from protruding in the axial direction by setting the length larger than the axial length.
