Abstract

A medium holder according to the invention includes a medium roll being a wound medium, and a medium holder unit that is mounted onto an end portion of the medium roll in an axial direction. The medium holder unit includes a movement mechanism having a rotating body that moves the medium roll.

First claim

What is claimed is:

1. A medium holder comprising:
a medium roll being a wound medium; and
a medium holder unit that is mounted onto an end portion of the medium roll in an axial direction, the medium holder unit including a movement mechanism having a rotating body that moves the medium roll.

2. The medium holder according to claim 1 , wherein
the movement mechanism includes the rotating body provided at a position at which the rotating body moves the medium roll in at least one of a direction intersecting the axial direction of the medium roll and a direction along the axial direction.

3. The medium holder according to claim 2 , wherein
the rotating body is provided to at least one of an end face and a side face of the medium holder unit.

4. The medium holder according to claim 1 , wherein
the movement mechanism is provided with a lock mechanism that locks the rotating body.

5. The medium holder according to claim 4 , wherein
the lock mechanism locks the rotating body when the medium holder receives an impact force of a specific threshold value or greater.

6. The medium holder according to claim 1 , further comprising
a cover that covers the medium roll, wherein the cover is housed in the medium holder unit.

7. The medium holder according to claim 1 , further comprising
a coupling member that couples together medium holder units mounted onto each of a plurality of medium rolls.

8. The medium holder according to claim 1 , wherein
the rotating body is configured from a shock absorbing material.

9. The medium holder according to claim 1 , wherein
the rotating body is provided through a shock absorbing mechanism.

10. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 1 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

11. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 2 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

12. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 3 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

13. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 4 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

14. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 5 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

15. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 6 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

16. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 7 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

17. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 8 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.

18. A liquid ejecting apparatus comprising:
a medium mounting portion onto which the medium holder of claim 9 is mounted;
a transport mechanism that pulls the medium out from the medium holder and transports the medium; and
a liquid ejecting head that ejects a liquid onto the medium transported by the transport mechanism.
