Abstract

A printer includes an apparatus main body including a recording head, and a duplexing unit configured to be removable with respect to the apparatus main body and forming a reverse transport path in which a sheet fed from the recording head side is reversed. The sheet width (for example, width of A4 short side) able to be transported to a region opposing the recording head through the reverse transport path is smaller than the width (for example, width of A4 long side) of the manual supply path, and in a case where the sheet on which recording is performed warps in the width direction, the extent of the warping is restricted to a predetermined range.

First claim

What is claimed is:

1. A recording apparatus that performs recording on a medium, comprising:
a first feeding portion that feeds the medium;
a recording portion that performs recording on the medium;
a medium receiving portion that receives the medium discharged from the recording portion;
a first transport path that transports the medium from the first feeding portion to the medium receiving portion via the recording portion; and
a second transport path that is a path for reversing the medium, on the surface of which recording is performed, and for performing recording on the rear surface,
wherein the second transport path is branched from a branching portion of the first transport path, and is merged with a merging portion of the first transport path which is positioned upstream from the branching portion,
wherein the width of the second transport path is narrower than the width of the first transport path.

2. The recording apparatus according to claim 1 ,
wherein the second transport path includes a reversing path which reverses the medium, and
wherein the reversing path merges with the merging portion of the first transport path.

3. The recording apparatus according to claim 2 ,
wherein, at least a portion of the second transport path is formed by a unit that is attachable and detachable with respect to an apparatus main body that includes the recording portion.

4. The recording apparatus according to claim 1 ,
wherein a region occupied by the recording portion and the region occupied by the second transport path at least partially overlap with each other in the height direction of the apparatus.

5. The recording apparatus according to claim 1 ,
wherein a branching portion where the branching portion of the first transport path is positioned on the downstream side in the transport direction of the medium with respect to the recording portion during execution of recording.

6. The recording apparatus according to claim 1 , further comprising:
a second feeding portion that feeds the medium,
wherein the medium fed via the second feeding portion joins to the second transport path.

7. The recording apparatus according to claim 1 ,
wherein the first feeding portion is a manual feeding portion for manually feeding the medium.

8. The recording apparatus according to claim 1 ,
wherein the second feeding portion is a sheet cassette, and
wherein a plurality of sheet cassettes is provided.

9. The recording apparatus according to claim 1 ,
wherein the feeding reference position of the medium in the width direction of the feeding portion is the center.

10. The recording apparatus according to claim 1 ,
wherein the recording portion includes a liquid supply tube having a moving body that performs recording by ejecting a liquid to a sheet-like medium,
guides the liquid sent from a liquid accommodating body in which the liquid is accommodated to the recording portion, and
includes a deforming movable portion that deforms so as to follow the movement of the moving body, and
wherein at least a portion of the liquid accommodating body is arranged outside the apparatus main body.

11. A recording apparatus that performs recording on a medium, comprising, in an apparatus main body:
a recording portion that performs recording on the medium;
a medium discharge port for discharging the medium on which recording is performed,
a first feeding portion that includes an insertion port for the medium, and that is able to feed the medium inserted from the insertion port to the recording portion;
a first transport path that extends from the insertion portion of the first feeding portion to the medium discharge port via the recording portion;
a second feeding portion that includes a mounting portion on which a plurality of sheets of the medium is mountable in a stacked state, and that is able to feed and reverse the medium from on the mounting portion to the recording portion; and
a second transport path that extends from the second feeding portion, and that merges with the first transport path,
wherein the mounting portion of the second feeding portion is positioned below the recording portion,
and
wherein the width of the first transport path is larger than the width of the second transport path.

12. The recording apparatus according to claim 11 , further comprising:
wherein the medium discharge port is larger than the width of the mounting portion of the second feeding portion.

13. The recording apparatus according to claim 11 , further comprising:
a medium receiving portion that receives the medium discharged from the recording portion,
wherein the dimension of the medium receiving portion in the width direction that intersects the discharge direction of the medium is smaller than the width of the first transport path.

14. The recording apparatus according to claim 13 ,
wherein a medium support portion that supports the medium fed from the first feeding portion from the gravity direction side on both sides in the width direction that intersects the discharge direction of the medium is provided on the medium discharge port.

15. The recording apparatus according to claim 14 ,
wherein an inclined location of an uphill slope in which the medium discharged from the recording portion towards the medium discharge port is gradually raised to the antigravity direction side is formed on the medium support portion.

16. The recording apparatus according to claim 11 ,
wherein an operation panel is arranged on a front surface side of the apparatus main body that is the discharge direction side of the medium discharged from the recording portion, and
wherein the dimension of the operation panel in the width direction is formed with the same dimension as the dimension in the width of the medium discharge port.
