SHEET FEEDING APPARATUS AND IMAGE FORMING SYSTEM

摘要

There are provided a sheet feeding apparatus and an image forming system which can horizontally maintain a posture of a topmost envelope in stored envelopes, by a simple configuration. The sheet feeding apparatus includes: a stacking surface portion 321; a sheet feeding roller 313; a pressing surface portion 362; and a curve forming portion 363. A length of the stacking surface portion 321 in a width direction is shorter than a length of each of envelopes P in a width direction. The pressing surface portion 362 is pressed by the sheet feeding roller 313 via the envelopes P. The curve forming portion 363 is arranged outside the sheet feeding roller 313 in a width direction, projects more upward in a vertical direction than the pressing surface portion 362, and supports the plurality of stacked envelopes P with a predetermined size.

主权项

1. A sheet feeding apparatus comprising:
a stacking surface portion on which a plurality of envelopes with a predetermined size can be stacked, the stacking surface portion having a length in a width direction perpendicular to a conveying direction of the envelopes with the predetermined size and also perpendicular to a vertical direction thereof being shorter than a length of each of the envelopes with the predetermined size in a width direction; a sheet feeding roller that comes into contact with the envelope with the predetermined size arranged at a top of the plurality of envelopes with the predetermined size in the vertical direction, the envelopes being stacked on the stacking surface portion, and conveys the envelopes with the predetermined size; a pressing surface portion pressed by the sheet feeding roller via the envelopes with the predetermined size; and a curve forming portion that is arranged outside the sheet feeding roller in the width direction, that projects more upward in the vertical direction than the pressing surface portion, and that supports the plurality of stacked envelopes with the predetermined size.
