Abstract
An image forming apparatus includes a sheet feeding device having a separation pad holding unit, a separation pad fixing unit, and a compression unit while vibration damping unit(such as a sponge member and a Mylar member) that is attached to the compression unit does not contact the separation pad holding unit and the separation pad fixing unit.
Claims11
A sheet feeding device for feeding a sheet, the sheet feeding device comprising:
- a feeding unit configured to feed sheets;
- a separation unit configured to separate the sheets fed by the feeding unit one by one;
- a holding unit configured to hold the separation unit;
- a pressure unit configured to press the holding unit toward the feeding unit while one side of the pressure unit contacts the holding unit;
- a fixing unit that contacts another side of the pressure unit;
- and
- a vibration damping unit attached to the pressure unit and configured to reduce vibration of the pressure unit,
- wherein the vibration damping unit is arranged at a position where the vibration damping unit does not contact both the holding unit and the fixing unit.
A sheet feeding device for feeding a sheet, the sheet feeding device comprising:
- a feeding unit configured to feed sheets;
- a separation unit configured to separate the sheets fed by the feeding unit one by one;
- a holding unit configured to hold the separation unit;
- a pressure unit configured to press the holding unit toward the feeding unit while one side of the pressure unit contacts the holding unit;
- a fixing unit that contacts another side of the pressure unit;
- and
- a vibration damping unit attached to the pressure unit and configured to reduce vibration of the pressure unit,
- wherein the vibration damping unit includes a hole, and the pressure unit is arranged to pass through the hole, and the vibration damping unit reduces vibration of the pressure unit by air resistance.
An image forming apparatus for forming an image on a sheet, the image forming apparatus comprising:
- a feeding unit configured to feed sheets;
- a separation unit configured to separate the sheets fed by the feeding unit one by one;
- a holding unit configured to hold the separation unit;
- a pressure unit configured to press the holding unit toward the feeding unit while one side of the pressure unit contacts the holding unit;
- a fixing unit that contacts another side of the pressure unit;
- a vibration damping unit attached to the pressure unit and configured to reduce vibration of the pressure unit;
- and
- an image forming unit configured to form an image on the sheet fed by the feeding unit,
- wherein the vibration damping unit is arranged at a position where the vibration damping unit does not contact both the holding unit and the fixing unit.
