Abstract

An image processing device includes first and second feeding units. The first feeding unit feeds a sheet toward the second feeding unit in a sheet feeding direction via a sheet feeding path. The device further includes an image processing portion. The first feeding unit is in the path upstream of the processing portion and includes a first shaft rotating in the feeding direction. The second feeding unit is in the path downstream of the processing portion, and the first and the second units feed and hold the sheet. The second feeding unit includes a second shaft rotating in the feeding direction. The device includes a first supporting member supporting first and second ends of the first shaft, a second supporting member supporting first and second ends of the second shaft, and a third supporting member supporting one shaft at a predetermined portion which is not either end of either shaft.

Dependent claims

An image processing device comprising:

a conveying mechanism configured to convey a sheet in a conveyance direction along a conveyance path;
and
a sensor disposed in the conveyance path;
the conveying mechanism comprising:
a first shaft disposed downstream of the sensor in the conveyance direction and having a first-shaft first supported portion, a first-shaft second supported portion and a first-shaft third supported portion positioned between the first-shaft first supported portion and the first-shaft second supported portion;
a second shaft disposed upstream of the sensor in the conveyance direction and having a second-shaft first supported portion and a second-shaft second supported portion;
a first-shaft first supporting portion configured to support the first-shaft first supported portion and having a bearing configured to receive the first-shaft first supported portion;
a first-shaft second supporting portion configured to support the first-shaft second supported portion and having a bearing configured to receive the first-shaft second supported portion;
a first-shaft third supporting portion configured to support the first-shaft third supported portion at an upstream side of the conveyance direction and having a bearing configured to receive the first-shaft third supported portion;
a second-shaft first supporting portion configured to support the second-shaft first supported portion;
and
a second-shaft second supporting portion configured to support the second-shaft second supported portion;
wherein a velocity at which the first shaft is rotated is greater than a velocity at which the second shaft is rotated.
