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 is disclosed. The sheet feeding apparatus includes a first transmission device driven by the motor for generating a driving force, a second transmission device driven by the first transmission device when the driving force for driving the 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 the second transmission device to rotate in the first direction for moving from the initial position to the sheet feeding position where the third transmission device in contact with a sheet while the motor rotates in the first direction and the driving force for driving the second transmission device is smaller than the threshold value so that when the driving force for driving the second transmission device becomes larger than the threshold value, the third transmission device feeds the sheet.

Abstract: A paper pickup mechanism for automatically picking up a paper is provided. The paper pickup mechanism includes a system motor for proceeding a first-direction rotation, and a second-direction rotation, a mounting shaft switching between a starting position and a pickup position, a first device driven by the system motor, and a second device driven by the first drive device, wherein the mounting shaft is driven by the first device to be switched from the starting position to the pickup position till the mounting shaft is limited by the paper while the system motor proceeds the first-direction rotation and the second device suffers an external force having a value less than a threshold, while the value of the external force suffered by the second device is larger than the threshold, so that the second drive device is started to move the paper, and while the system motor proceeds the second-direction rotation and the second device suffers the external force having the value less than the threshold, the mounting shaft is driven by the first device to be restored from the pickup position to the starting position.
