Abstract
A sheet supplying apparatus has a sheet support for supporting sheets, and a sheet supply roller for feeding out the sheets supported by the sheet support. An abutment member is pivotally supported to be rocked between a regulating position to regulate a tip end of the sheets supported by the sheet support and a non-regulating position to allow supply of the sheets by the sheet supply roller. An operation unit shifts the abutment member from the regulating position to the non-regulating position when the sheets are supplied by the sheet supply roller and shifts the abutment member from the non-regulating position to the regulating position after the sheets are supplied.
Claims13
A sheet supplying apparatus comprising:
- sheet supporting means for supporting sheets;
- rotatable sheet supply means for feeding out a sheet from the sheets supported by said sheet supporting means;
- an abutment member pivotally supported to be rocked between a regulating position to regulate a tip end of the sheets supported by said sheet supporting means and a non-regulating position to allow supply of the sheet by said sheet supply means, wherein an angle between a surface of the sheet supported by said sheet supporting means and the abutment member disposed at the regulating position is smaller than an angle between the surface of the sheets supported by said sheet supporting means and the abutment surface of said abutment member disposed at the non-regulating position;
- and
- operation means in synchronism with a rotation of said rotatable sheet supply means for releasing said abutment member so as to shift said abutment member from said regulating position to said non-regulating position when the sheet is supplied by said sheet supply means, and said operation means for shifting said abutment member from said non-regulating position to said regulating position and for regulating said abutment member at the regulating position after the sheet is supplied.
An image forming apparatus comprising:
- sheet supporting means for supporting sheets;
- rotatable sheet supply means for feeding out a sheet from the sheets supported by said sheet supporting means;
- an abutment member pivotally supported to be rocked between a regulating position to regulate a tip end of the sheets supported by said sheet supporting means and a non-regulating position to allow supply of the sheet by said sheet supply means, wherein an angle between a surface of the sheet supported by said sheet supporting means and the abutment member disposed at the regulating position is smaller than an angle between the surface of the sheets supported by said sheet supporting means and the abutment surface of said abutment member disposed at the non-regulating position;
- operation means in synchronism with a rotation of said rotatable sheet supply means for releasing said abutment member so as to shift said abutment member from said regulating position to said non-regulating position when the sheet is supplied by said sheet supply means, and said operation means for shifting said abutment member from said non-regulating position to said regulating position and for regulating said abutment member at the regulating position after the sheet is supplied;
- and
- an image forming means for forming an image on the sheet fed out by said sheet supply means.
