Abstract

In a printer for printing on a label of a continuous paper in a middle of feeding the continuous paper unwound from a paper sheet supply unit, while a depressed portion is disposed below a damper portion, a width adjustment guiding portion, which contacts an outer edge in a width direction of the continuous paper to guide a feed of the continuous paper, is disposed on a lower portion of the damper portion such that the lower end portion of the width adjustment guiding portion is positioned within the depressed portion.

First claim

The invention claimed is:

1. A printer, comprising:
a feeding unit configured to feed a print medium;
a printing head portion configured to print on the print medium;
a guiding unit that includes a guiding portion disposed upstream of the printing head portion in a printing direction; and
a depressed portion formed on a part of a bottom surface within a printer chassis, wherein
the guiding unit, except the guiding portion, is arranged at a position away from the depressed portion, and
a part of the guiding portion is positioned within the depressed portion.

2. The printer according to claim 1 , further comprising:
a damper portion disposed between the printing head portion and the feeding unit to give tension to the print medium, wherein
the guiding unit is disposed on the damper portion.

3. The printer according to claim 2 , wherein
the damper portion comprises an inner damper portion, wherein
a position where the inner damper portion abuts on the print medium is positioned downstream in the printing direction of the print medium with respect to a position of the depressed portion.

4. The printer according to claim 1 , wherein
the guiding portion is away from a bottom surface of the depressed portion.

5. The printer according to claim 1 , further comprising:
a damper portion configured to give tension to the print medium, wherein
the damper portion is swingably installed.

6. The printer according to claim 1 , further comprising:
a damper portion configured to give tension to the print medium, wherein
the damper portion includes an outer damper portion and an inner damper portion, the inner damper portion is swingably supported on the outer damper portion.

7. The printer according to claim 6 , wherein
the guiding unit is disposed on the outer damper portion.

8. The printer according to claim 6 , wherein
the inner damper portion includes a paper sheet contact portion configured to contact the print medium, the paper sheet contact portion of the inner damper portion positioned downstream in the printing direction with respect to the depressed portion.

9. The printer according to claim 6 , wherein
the inner damper portion is supported on an upstream side of the outer damper portion with respect to the printing direction,
the inner damper portion includes a paper sheet contact portion configured to contact the print medium,
the outer damper portion includes a paper sheet contact portion configured to contact the print medium, and
a height of the paper sheet contact portion of the inner damper portion is disposed at a lower position than a height of the paper sheet contact portion of the outer damper portion.

10. The printer according to claim 8 , wherein
the paper sheet contact portion of the inner damper portion is positioned downstream of a paper sheet contact portion of the outer damper portion with respect to the printing direction.

11. The printer according to claim 1 , wherein
the feeding unit is further configured to feed the print medium in a direction opposite to the printing direction.

12. The printer according to claim 1 , wherein
the depressed portion is formed on a part of the bottom surface within the printer chassis continuously to the bottom surface.

13. The printer according to claim 1 , wherein
the print medium includes a liner sheet and a plurality of labels temporarily adhered at predetermined intervals along a longitudinal direction of the liner sheet.

14. The printer according to claim 1 , wherein
the guiding portion includes a guiding piece,
the guiding piece includes an inclined surface which increases from an upstream side towards a downstream side of the printing direction, and
the guiding piece abuts one side edge of the print medium.

15. The printer according to claim 1 , wherein
a lower end portion of the guiding portion is positioned between the bottom surface of the printer chassis and a bottom surface of the depressed portion.

16. The printer according to claim 1 , wherein
the guiding unit is disposed at a height beneath the printing head portion.

17. A printer, comprising:
a feeding unit configured to feed a print medium;
a printing head portion configured to print on the print medium;
a damper portion disposed at an upstream side of a feeding direction to give tension to the print medium; and
a guiding portion disposed at the damper portion, the guiding portion contacting at least one side edge of the print medium to guide the feed of the print medium, wherein
a depressed portion is formed on a part of a bottom surface within a printer chassis, and
a part of the guiding portion is positioned within the depressed portion.

18. The printer according to claim 17 , further comprising:
a medium supply unit configured to supply the print medium to the feeding unit.

19. The printer according to claim 17 , wherein
the feeding unit is further configured to feed the print medium in a direction opposite to the feeding direction.

20. The printer according to claim 17 , wherein
the print medium includes a liner sheet and a plurality of labels temporarily adhered at predetermined intervals along a longitudinal direction of the liner sheet.

21. The printer according to claim 17 , wherein
the guiding portion includes a guiding piece,
the guiding piece includes an inclined surface which increases from an upstream side towards a downstream side with respect to the feeding direction, and
the guiding piece abuts one side edge of the print medium.

22. The printer according to claim 17 , wherein
a lower end portion of the guiding portion is positioned between the bottom surface of the printer chassis and a bottom surface of the depressed portion.

23. The printer according to claim 17 , wherein
the guiding portion is disposed at a height beneath the printing head portion.

24. A printer, comprising:
a feeding unit configured to feed a print medium;
a printing head portion configured to print on the print medium;
a guiding unit that includes a guiding portion disposed upstream of the printing head portion in a printing direction; and
a depressed portion formed in a floor surface of a printer chassis, wherein
a part of the guiding portion is positioned within the depressed portion.

25. The printer according to claim 24 , wherein
the guiding portion is away from a bottom surface of the depressed portion.

26. The printer according to claim 24 , further comprising:
a damper portion configured to give tension to the print medium, wherein
the damper portion is swingably installed.

27. The printer according to claim 24 , further comprising:
a damper portion configured to give tension to the print medium, wherein
the damper portion includes an outer damper portion and an inner damper portion, and
the inner damper portion is swingably supported on the outer damper portion.
