Abstract:
A sheet feeding apparatus, to be used in an automatic sheet feeder having a motor rotatable in a first direction and a second direction, comprising:a first transmission device driven by said motor for generating a driving force; a second transmission device driven by said first transmission device when said driving force for driving said second transmission device is larger than a threshold value; and a third transmission device moving between an initial position and a sheet feeding position and driven by said second transmission device to rotate in said first direction for moving from said initial position to said sheet feeding position where said third transmission device is in contact with a sheet while said motor rotates in said first direction and said driving force for driving said second transmission device is smaller than said threshold value so that when said driving force for driving said second transmission device becomes larger than said threshold value, said third transmission device feeds said sheet.
