Abstract
Torque is applied to a separation roller of an image processing apparatus when a leading edge of the sheet in a transport direction reaches a first transport roller and when the leading edge of the sheet in the transport direction reaches a transport unit. Torque to the separation roller is cut off after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches the image processing unit.
Claims14
An image processing apparatus comprising:
- an image processing unit disposed along a transport path;
- a separation roller located along the transport path;
- a frictional resistance body that is disposed at a position across the transport path from and opposing the separation roller;
- a first transport roller including a first roller portion and a first shaft portion that holds the first roller portion, the first transport roller being provided along the transport path downstream of the separation roller, the first shaft portion extending entirely across the transport path in a width direction;
- a second transport roller displaceably positioned across the transport path from the first transport roller to cooperatively nip the sheet, the second transport roller including a second roller portion and a second shaft portion that holds the second roller portion, the second shaft portion extending entirely across the transport path in the width direction and being displaceable away from and towards the first transport roller;
- a pair of pressing members configured to press ends sides of the second transport roller towards the first transport roller;
- a transport unit that is located downstream of the first transport roller along the transport path, wherein at least a portion of the transport unit is located upstream of the image processing unit along the transport path;
- and
- a drive controller configured to control the separation roller in a first control mode, wherein in the first control mode, the drive controller is configured to:
- apply torque to the separation roller when a leading edge of the sheet in a transport direction reaches the first transport roller and when the leading edge of the sheet in the transport direction reaches the transport unit;
- and
- cut off torque to the separation roller after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches the image processing unit.

A method of operation of an image processing apparatus, the method comprising:
- applying torque to a separation roller located along a transport path and across from an opposing frictional resistance body when a leading edge of a sheet in a transport direction reaches a first transport roller provided along the transport path downstream of the separation roller and when the leading edge of the sheet in the transport direction reaches a transport unit located downstream of the first transport roller, the first transport roller including a first roller portion and a first shaft portion that holds the first roller portion, the first shaft portion extending entirely across the transport path in a width direction, the first transport roller cooperating with a second transport roller displaceably positioned across the transport path from the first transport roller to nip the sheet;
- and
- cutting off torque to the separation roller after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches an image processing unit of the image processing device.
A non-transitory, computer-readable media storing computer-readable instructions therein that, when executed by at least one processor of an image processing apparatus, cause the image processing apparatus to:
- apply torque to a separation roller located along a transport path and across from an opposing frictional resistance body when a leading edge of a sheet in a transport direction reaches a first transport roller provided along the transport path downstream of the separation roller and when the leading edge of the sheet in the transport direction reaches a transport unit located downstream of the first transport roller, the first transport roller including a first roller portion and a first shaft portion that holds the first roller portion, the first shaft portion extending entirely across the transport path in a width direction, the first transport roller cooperating with a second transport roller displaceably positioned across the transport path from the first transport roller to nip the sheet;
- and
- cut off torque to the separation roller after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches an image processing unit of the image processing device.
