Abstract

A recording device includes a recording unit configured to record on a medium, a transportation unit configured to transport the medium, a driving member, a plurality of gears configured to transmit a driving force of the driving member, and a sound absorber having an opening and a hollow space in communication with the opening. The sound absorber is located between a side end of the medium being transported by the transportation unit and the plurality of gears.

First claim

What is claimed is:

1. A recording device comprising:
a recording unit configured to record on a medium;
a transportation unit configured to transport the medium;
a driving member;
a plurality of gears configured to transmit a driving force of the driving member; and
a sound absorber having an opening and a hollow space in communication with the opening, wherein
the sound absorber is located between a side end of the medium being transported by the transportation unit and the plurality of gears.

2. The recording device according to claim 1 , wherein the plurality of gears is configured to transmit the driving force of the driving member to the transportation unit.

3. The recording device according to claim 2 , further comprising a support facing the recording unit and supporting the medium, wherein
the sound absorber is located between the support and the plurality of gears.

4. The recording device according to claim 3 , wherein the sound absorber includes a case and a cover attached to the case and having the opening.

5. The recording device according to claim 4 , wherein the case is included in a frame member constituting the support.

6. The recording device according to claim 4 , wherein the cover is configured to be moved relative to the case.

7. The recording device according to claim 6 , further comprising a displacement mechanism configured to move the cover relative to the case, wherein
the displacement mechanism includes a cam configured to come in contact with the cover and the cam moves the cover in a vertical direction when rotated.

8. The recording device according to claim 7 , wherein the recording unit includes a head configured to eject a liquid onto the medium and a carriage having the head thereon and configured to scan the medium,
the displacement mechanism includes an attachment shaft to which the cam is attached, an interlocking gear attached to the attachment shaft, and a trigger gear configured to mesh with the interlocking gear, and
the trigger gear is configured to move to a first position to mesh with the interlocking gear and to a second position to be unmeshed from the interlocking gear, and the trigger gear is moved from the second position to the first position by being pushed by the carriage.

9. The recording device according to claim 7 , wherein the displacement mechanism moves the cover depending on a transportation speed of the medium transported by the transportation unit.

10. The recording device according to claim 1 , further comprising a transportation path along which the medium is transported by the transportation unit, wherein
the transportation unit includes a first transportation roller located upstream of the recording unit on the transportation path and a second transportation roller located between the recording unit and the first transportation roller on the transportation path,
the driving member includes a first motor configured to drive the first transportation roller and a second motor configured to drive the second transportation roller, and
the plurality of gears transmits the driving force of the second motor to the second transportation roller.
