Abstract

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is constituted of an outer damper portion and an inner damper portion, which is disposed at a downstream side of feed of the outer damper portion.

First claim

1 - 7 . (canceled)

8 . A printer, comprising:
a medium supply portion configured to supply a print medium; a feeding unit configured to feed the print medium supplied from the medium supply unit along a medium feed path; a printing unit disposed in the medium feed path to print on the print medium; a first damper portion configured to swing so that a medium contact portion, which contacts the print medium in the medium feed path, gives tension to the print medium between the printing unit and the medium supply portion; and a second damper portion configured to swing so that a medium contact portion, which contacts the print medium in the medium feed path, gives tension to the print medium between the printing unit and the medium contact portion of the first damper portion, and between the medium contact portion of the first damper portion and a chassis surface facing the medium contact portion of the first damper portion.

9 . The printer according to claim 8 , wherein
the second damper portion is swingably journaled to the first damper portion.

10 . The printer according to claim 8 , wherein
the first damper portion and the second damper portion are made of a transparent material.

11 . The printer according to claim 8 , wherein
the first damper portion is configured to swing around a downstream side shaft at a downstream side in a feed direction of the print medium and is arranged to extend obliquely downward to an upstream side in the feed direction.

12 . The printer according to claim 11 , wherein
the second damper portion is configured to swing around a upstream side shaft at the upstream side in the feed direction of the print medium and is arranged to extend obliquely downward to the downstream side in the feed direction.

13 . The printer according to claim 8 , wherein
the medium contact portion of the second damper portion is disposed at a position lower than a position of the medium contact portion of the first damper portion.

14 . The printer according to claim 8 , wherein
the first damper portion includes a width adjustment guiding portion, the width adjustment guiding portion being configured to abut on an end portion in a width direction of the print medium to guide a feed.

15 . The printer according to claim 8 , wherein
the print medium is loaded with a paper passing route contacting the second damper portion or a paper passing route contacting both the first damper portion and the second damper portion.
