A sheet feeding apparatus for sequentially feeding sheet material from a sheet supporting member which supports a stack of sheet material. The feeding apparatus employs a mechanism to cause a feeding roller to engage or disengage the stack. A driving source is provided for transmitting a driving force to the feeding roller and the mechanism for causing the feeding roller to engage or disengage the stack. First and second transmitting mechanisms are provided for transmitting the driving force to the feeding roller and the mechanism for causing engagement or disengagement of the feeding roller and stack respectively. A stop device movable between a position to allow transmission of the driving force to the first and second transmitting mechanisms and a position where the transmitting mechanisms are prevented from transmitting the driving force. The feeding roller, the mechanism causing engagement or disengagement of the feeding roller with the stack and the first and second transmitting mechanisms are disclosed as co-axial.
