Abstract

The present invention complies a side end regulating mechanism to regulate a side end position in the width direction of sheets supported by a cassette main body 3 is configured with a side end reference portion 5 which is to be a reference in the width direction for sheet feeding and side end regulating portion 6 which is arranged to be opposed to the side end reference portion 5 with a sheet pressing member 8 to which a force is applied so as to press the sheet elastically toward the side end reference portion 5. Then, an angle adjusting member 14 arranged at the side end reference portion 5 changes an incline angle of a reference surface which is to be a reference in the sheet width direction for sheet feeding by inclining the side end reference portion 5 in the width direction.

Claims8

Dependent claims

A sheet feeding apparatus, comprising:

a sheet supporting portion which supports a plurality of sheets;
a side end regulating mechanism which is arranged in a width direction perpendicular to a sheet feeding direction and regulates a position of the sheets supported by the sheet supporting portion by contacting an end part of the sheets in the width direction;
and
a sheet feeding portion which feeds the top sheet of the sheets supported by the sheet supporting portion and regulated by the side end regulating mechanism,
wherein the side end regulating mechanism includes a reference side regulating portion having a reference surface to be a reference in the sheet width direction for sheet feeding, a side end regulating portion which is arranged to be opposed to the reference side regulating portion with a sheet pressing member to apply a force to the sheets toward the reference surface, and
an adjusting portion which changes an incline angle of the reference surface which is supported to be capable of inclining at the lower side of the reference surface as a fulcrum.

An image forming apparatus, comprising:

a sheet supporting portion which supports a plurality of sheets;
a side end regulating mechanism which is arranged in a width direction perpendicular to a sheet feeding direction and regulates a position of the sheets supported by the sheet supporting portion by contacting an end part of the sheets in the width direction;
a sheet feeding portion which feeds the top sheet of the sheets supported by the sheet supporting portion and regulated by the side end regulating mechanism,
wherein the side end regulating mechanism includes a reference side regulating portion having a reference surface to be a reference in the sheet width direction for sheet feeding, a side end regulating portion which is arranged to be opposed to the reference side regulating portion with a sheet pressing member to apply a force to the sheets toward the reference surface,
an image forming portion which forms an image on the sheet fed from the sheet feeding portion;
and
an adjusting portion which changes an incline angle of the reference surface which is supported to be capable of inclining at the lower side of the reference surface as a fulcrum.
