Abstract

Provided is a recording apparatus including a transporting unit capable of transporting a medium, a detecting unit capable of detecting a transport direction in which the medium is transported by the transporting unit, a recording unit capable of performing recording on the medium transported by the transporting unit, and a member capable of coming into contact with and separating from a side of the medium opposite to a recording side on which recording is performed by the recording unit and coming into contact with at least a part of the opposite side of the medium to prevent skewing of the transported medium when the medium is transported by the transporting unit.

First claim

What is claimed is:

1 . A recording apparatus comprising:
a transporting unit that is capable of transporting a medium; a detecting unit that is capable of detecting a transport direction in which the medium is transported by the transporting unit; a recording unit that is capable of performing recording on the medium transported by the transporting unit; a frictional force exerting unit that is capable of coming into contact with and separating from a side of the medium opposite to a recording side on which recording is performed by the recording unit and is capable of coming into contact with at least a part of the opposite side of the medium to exert frictional force on the medium when the medium is transported by the transporting unit; and a control unit that controls the contact of the frictional force exerting unit with the medium on the basis of a detection result from the detecting unit.

2 . The recording apparatus according to claim 1 ,
wherein the frictional force exerting unit is an extending member that extends in the intersecting direction, and the control unit is capable of controlling a region of the frictional force exerting unit coming into contact with the medium in the intersecting direction by changing the angle between the medium and the frictional force exerting unit in the intersecting direction viewed from the transport direction.

3 . The recording apparatus according to claim 2 ,
wherein the frictional force exerting unit is an extending member that includes an arc face convex toward the opposite side when viewed from the transport direction.

4 . The recording apparatus according to claim 1 , further comprising:
a moving object that moves together with the recording unit in the intersecting direction, wherein the detecting unit is disposed in the moving object.

5 . The recording apparatus according to claim 1 ,
wherein the detecting unit is disposed further upstream of the transport direction than the recording unit.

6 . The recording apparatus according to claim 1 , further comprising:
a winding unit that is disposed further downstream of the transport direction than the recording unit and is capable of winding the medium, wherein the detecting unit is disposed further downstream of the transport direction than the recording unit as well as further upstream of the transport direction than the winding unit.

7 . The recording apparatus according to claim 1 ,
wherein the length of the frictional force exerting unit in the intersecting direction is greater than or equal to the length of transport of the medium in the intersecting direction on a transport path of the medium.

8 . The recording apparatus according to claim 1 , further comprising:
as the frictional force exerting unit, a first frictional force exerting unit that exerts frictional force increasing from one side to the other side of the medium in the intersecting direction on the medium and a second frictional force exerting unit that exerts frictional force decreasing from the one side to the other side on the medium, wherein the control unit is capable of controlling contact of the first frictional force exerting unit and the second frictional force exerting unit with the medium on the basis of the detection result from the detecting unit.

9 . A recording method for a recording apparatus including a transporting unit capable of transporting a medium, a detecting unit capable of detecting a transport direction in which the medium is transported by the transporting unit, and a recording unit capable of performing recording on the medium transported by the transporting unit, the method comprising:
controlling contact of a frictional force exerting unit with the medium on the basis of a detection result from the detecting unit, the frictional force exerting unit being capable of coming into contact with and separating from a side of the medium opposite to a recording side on which recording is performed by the recording unit and being capable of coming into contact with at least a part of the opposite side of the medium to exert frictional force on the medium when the medium is transported by the transporting unit, and transporting the medium to perform recording on the medium.

10 . A recording apparatus comprising:
a transporting unit that is capable of transporting a medium; a detecting unit that is capable of detecting a transport direction in which the medium is transported by the transporting unit; a recording unit that is capable of performing recording on the medium transported by the transporting unit; a rotating object that includes a contactable region having a coefficient of friction against the medium increasing from one side to the other side of the rotating object in an intersecting direction intersecting with the transport direction as well as a contactable region having a coefficient of friction against the medium decreasing from the one side to the other side and is capable of coming into contact with a side of the medium opposite to a recording side on which recording is performed by the recording unit while including a rotating shaft in the intersecting direction; and a control unit that controls the rotating object on the basis of a detection result from the detecting unit to change a region of the rotating object coming into contact with the medium.

11 . A recording apparatus comprising:
a transporting unit that is capable of transporting a medium; a detecting unit that is capable of detecting a transport direction in which the medium is transported by the transporting unit; a recording unit that is capable of performing recording on the medium transported by the transporting unit; a rotating object that includes a contactable region of which the area of contact with the medium increases from one side to the other side of the rotating object in an intersecting direction intersecting with the transport direction as well as a contactable region of which the area of contact with the medium decreases from the one side to the other side and is capable of coming into contact with a side of the medium opposite to a recording side on which recording is performed by the recording unit while including a rotating shaft in the intersecting direction; and a control unit that controls the rotating object on the basis of a detection result from the detecting unit to change a region of the rotating object coming into contact with the medium.

12 . The recording apparatus according to claim 10 , further comprising:
a moving object that moves together with the recording unit in the intersecting direction, wherein the detecting unit is disposed in the moving object.

13 . The recording apparatus according to claim 10 ,
wherein the detecting unit is disposed further upstream of the transport direction than the recording unit.
