Abstract
The present invention provides a sheet feeding apparatus that has sheet feeding device for abutting against an upper surface of a sheet stacked and feeding out the sheet, biasing device for biasing the sheet feeding device toward the upper surface of the sheet, and lifting and lowering device for lifting and lowering the sheet feeding device, the lifting and lowering device including a holding member for engaging with the sheet feeding device and shifting the sheet feeding device in an up-and-down direction by a motor, and maintaining device for regulating the holding member so as to maintain the sheet feeding device at a position where the sheet feeding device is spaced apart from the upper surface of the sheet, in opposition to a biasing force of the biasing device.
Claims11
A sheet feeding apparatus comprising:
- sheet feeding means for abutting against an upper surface of a sheet stacked and feeding out the sheet;
- biasing means for biasing said sheet feeding means toward the upper surface of the sheet;
- and
- lifting and lowering means for lifting and lowering said sheet feeding means;
- said lifting and lowering means including a holding member for engaging with said sheet feeding means and shifting said sheet feeding means in an up-and-down direction by a motor, and maintaining means for regulating said holding member so as to maintain said sheet feeding means at a position where said sheet feeding means is spaced apart from the upper surface of the sheet, in opposition to a biasing force of said biasing means.
An image forming apparatus comprising:
- sheet feeding means for abutting against an upper surface of a sheet stacked and feeding out the sheet toward an image forming portion;
- biasing means for biasing said sheet feeding means toward the upper surface of the sheet;
- and
- lifting and lowering means for lifting and lowering said sheet feeding means;
- said lifting and lowering means including a holding member for engaging with said sheet feeding means and shifting said sheet feeding means in an up-and-down direction by a motor, and maintaining means for regulating said holding member so as to maintain said sheet feeding means at a position where said sheet feeding means is spaced apart from the upper surface of the sheet, in opposition to a biasing force of said biasing means.
