が複雑であった。However, in a sheet feeding device having a cut sheet guide having a structure as shown in FIGS. 4 and 5, if a cut sheet with a peculiarity is set, the cut sheet will be placed sideways. Since the end faces swell in the direction in which the cut sheets are bundled, the lateral end surface of the cut sheets rubs against the guides for the cut sheets, which causes resistance and a paper feeding failure is likely to occur. Further, the sheet feeding device having the structure as shown in FIG. 6 has a slightly complicated structure only for restricting the habit of the edge of the cut sheet.

A sheet pressure plate to be pushed up, a paper feed roller that comes into contact with the uppermost layer of the cut sheet and pulls out the cut sheet, and a cut sheet that regulates the cut sheet when setting the cut sheet and serves as a guide for the cut sheet. A sheet feeding device including a sheet guide is characterized in that a portion near the side wall member of the single-cut sheet guide is bent in a direction away from the sheet surface of the single-cut sheet.

部材２と接している。The side wall member 2 regulates the side portion of the cut sheet 1. A receiving plate 3 that supports the leading end of the cut-sheet paper 1 is fixed to the lower portion of the side wall member 2. A sheet pressure plate 4 is provided in a space formed by the side wall member 2 and the receiving plate 3. Paper pressure plate 4
Are guided around a hopper shaft 8 that supports the entire hopper. A compression coil spring 5 is provided behind the sheet pressure plate 4 and presses the sheet pressure plate 4 forward. In front of the sheet pressure plate 4, there is a rotatable sheet feeding roller shaft 13. The paper feed roller 6 is passed through the paper feed roller shaft 13 and is interlocked with the paper feed roller shaft 13. Separation claws 7 are provided at positions in contact with both corners of the leading edge of the cut sheet 1. The paper feed roller 6 has
There is a paper feed roller cover 9 that covers the paper feed roller 6. Above the paper feed roller cover 9, there is a paper cut sheet guide 10 which is integrated with the paper feed roller cover 9 and serves as a guide when setting the cut paper 1. As can be seen from FIG. 3, in the cut sheet guide 10, the portion 10a near the side wall member 2 is bent in the direction away from the sheet surface of the cut sheet 1 and is in contact with the side wall member 2.

Since it does not, there is little paper feed resistance and it is possible to feed paper. Further, even when the cut sheet 1 has a large habit, a portion 10a of the cut sheet guide 10 close to the side wall member 2 is formed.
Is set at an angle such that the leading edge of the cut sheet does not come off from the separation claw 7, so that the cut sheet 1 can be easily set.
