Abstract

In accordance with an embodiment, a printer according to the embodiment includes: a holder of a rolled print medium. The holder includes a moving member that is provided to be slidable on a shaft member to be inserted through a support hole of the rolled print medium in an axial direction and includes a guide member that can stand and fall with respect to the shaft member. Further, the holder includes an adjustment member that makes a pressure contact force of a biasing member that presses the shaft member and the moving member together to restrain sliding movement of the moving member with respect to the shaft member larger in a standing state of the guide member than in a fallen state of the guide member.

First claim

What is claimed is:

1. A printer, comprising:
a holder that rotatably supports a rolled print medium; and
a printing unit that prints on the rolled print medium fed out from the holder, wherein
the holder includes
a shaft member to be inserted through a support hole formed in the rolled print medium in an axial direction,
a moving member that is provided to be slidable on the shaft member in the axial direction with respect to the shaft member and includes a guide member that can be in a standing state in which the guide member extends in a direction perpendicular to the axial direction and in a fallen state in which the quide member extends in the axial direction,
a biasing member that presses the shaft member and the moving member together to provide a braking force against sliding movement of the moving member with respect to the shaft member during the standing state and the fallen state of the quide member, and
an adjustment member that makes a pressure contact force applied by the biasing member to the shaft member and the moving member larger in the standing state of the guide member than in the fallen state of the guide member so that the braking force is larger in the standing state than in the fallen state.

2. The printer according to claim 1 , wherein
the adjustment member includes a biasing member support portion that supports the biasing member, a pressure contact portion that is biased by the biasing member to be pressed against the shaft member, and a guide member support portion that supports the guide member so that the guide member can stand and fall.

3. The printer according to claim 2 , wherein
the guide member includes a pressing portion that presses the adjustment member in a direction of compressing the biasing member in accordance with a standing operation with respect to the shaft member.

4. The printer according to claim 3 , wherein
the guide member support portion includes a holding-down portion that holds down a connecting shaft portion connecting the guide member so that the guide member can stand and fall, and
the pressing portion enters between the connecting shaft portion and the holding-down portion to press the adjustment member in accordance with the standing operation with respect to the shaft member.

5. The printer according to claim 4 , wherein
the pressing portion includes a tip portion that can be inserted between the connecting shaft portion and the holding-down portion.

6. The printer according to claim 1 , wherein
the adjustment member includes a biasing member support portion that supports the biasing member.

7. The printer according to claim 1 , wherein
the adjustment member includes a pressure contact portion that is biased by the biasing member to be pressed against the shaft member.

8. The printer according to claim 1 , wherein
the adjustment member includes a guide member support portion that supports the guide member so that the guide member can stand and fall.

9. The printer according to claim 1 , wherein
the adjustment member includes a biasing member support portion that supports the biasing member and a pressure contact portion that is biased by the biasing member to be pressed against the shaft member.

10. The printer according to claim 1 , wherein
the adjustment member includes a biasing member support portion that supports the biasing member and a guide member support portion that supports the guide member so that the guide member can stand and fall.
