Abstract

A printer includes a holder configured to house rolled recording paper, a cover that is attached to the holder to be openable and closable relative to the holder, and a contact part that is attached to the cover and configured to contact the recording paper. The contact part is configured such that the contact part substantially point-contacts the recording paper, and positions on the contact part contacting the recording paper change as the recording paper is unrolled.

First claim

The invention claimed is:

1. A printer, comprising:
a printer body including a holder;
a cover configured to open and close the holder, the cover and the holder forming a housing chamber for housing a roll of recording paper, the roll being an unattached roll that is placed in the housing chamber without being attached to a fixed rotational axis, the unattached roll having an outer circumferential surface thereof in direct contact with the housing chamber; and
a sound-absorbing material including one or more V-shaped angled portions and disposed in the housing chamber such that the recording paper contacts the sound-absorbing material is in direct contact with a portion of the outer circumferential surface of the unattached roll, the portion being circumferentially opposite a point where the recording paper leaves the unattached roll upon being unrolled from the unattached roll, wherein
the sound-absorbing material is configured to bias the recording paper in a direction away from the cover and reduce a moving force of the recording paper toward the cover and configured to absorb a rubbing sound generated when the recording paper contacts the sound-absorbing material; and
each of the V-shaped angled portions includes
a protruding peak portion, and
inclined portions that are located lateral to the peak portion and extend diagonally with respect to a width direction of the recording paper.

2. The printer as claimed in claim 1 , wherein the sound-absorbing material is attached to an inner wall of the cover to protrude from the inner wall and is configured such that the one or more V-shaped angled portions are pressed and deformed when the recording paper contacts the one or more V-shaped angled portions.

3. A printer, comprising:
a printer body including a holder;
a cover configured to open and close the holder, the cover and the holder forming a housing chamber for housing a roll of recording paper, the roll being an unattached roll that is placed in the housing chamber without being attached to a fixed rotational axis, the unattached roll having an outer circumferential surface thereof in direct contact with the housing chamber; and
a contact part made of a sound-absorbing material including one or more V-shaped angled portions and disposed in the housing chamber such that the contact part is in direct contact with a portion of the outer circumferential surface of the unattached roll, the portion being circumferentially opposite a point where the recording paper leaves the unattached roll upon being unrolled from the unattached roll, wherein
the contact part is configured to bias the recording paper in a direction away from the cover and configured to absorb a rubbing sound generated when the recording paper contacts the contact part; and
each of the V-shaped angled portions includes
a protruding peak portion, and
inclined portions that are located lateral to the peak portion and extend diagonally with respect to a width direction of the recording paper.

4. The printer as claimed in claim 3 , wherein the contact part is attached to an inner wall of the cover to protrude from the inner wall and is configured such that the one or more V-shaped angled portions are pressed and deformed when the recording paper contacts the one or more V-shaped angled portions.
