Abstract
A sheet feeding apparatus having a feeding device including a feeding member for feeding a sheet from a rest stand and a support member for supporting the feeding member, in which the support member swings about a rotary shaft provided at one end of the support member to thereby move the feeding device up and down. A force applying unit provided on the rotary shaft brings the feeding member into contact with the sheet on the rest stand with a predetermined force. The predetermined force is smaller than a force due to the gravitational force of the feeding device against the sheet on the rest stand.
Claims11
A sheet feeding apparatus comprising:
- a rest stand for setting a sheet;
- and
- a feeder for feeding the sheet from said rest stand,
- wherein said feeder swings about a rotary shaft to be movable up and down by a motor,
- said feeder abuts against the sheet on said rest stand with a predetermined normal force by force applying means provided on the rotary shaft, and
- upon disengaging the motor a force of the force applying means is smaller than a self-weight of said feeder.
