Abstract

A cutting device includes a fixed blade and a movable blade that slides past the fixed blade during cutting, and a cleaning tool with an adhesive removing element that comes into contact with a surface of the movable blade that faces the fixed blade during the cutting.

First claim

What is claimed is:

1. A cutting device comprising:
a fixed blade;
a movable blade configured to slide past the fixed blade; and
a cleaning tool with an adhesive removing element that comes into contact with a surface of the movable blade that faces the fixed blade.

2. The cutting device according to claim 1 , wherein the movable blade is provided to face an adhesive side of a label to be cut.

3. The cutting device according to claim 1 , wherein the fixed blade is provided to face a printed side of the label.

4. The cutting device according to claim 1 , wherein the fixed blade is provided upstream with respect to the movable blade in a label conveying direction.

5. The cutting device according to claim 1 , wherein the cleaning tool includes a square-shaped rod with four longitudinal surfaces and the adhesive removing element is provided on at least one of the four longitudinal surfaces.

6. The cutting device according to claim 5 , wherein the adhesive removing element includes a brush that extends outwardly from the at least one of the four longitudinal surfaces.

7. The cutting device according to claim 6 , wherein the brush is arranged along a straight horizontal line.

8. The cutting device according to claim 6 , wherein the brush is arranged along a straight line that is inclined with respect to a horizontal line and parallel to at least one cutting edge of the movable blade.

9. The cutting device according to claim 6 , wherein the brush is arranged along two straight lines that are inclined with respect to a horizontal line.

10. The cutting device according to claim 9 , wherein the two straight lines do not cross.

11. The cutting device according to claim 9 , wherein the two straight lines cross each other.

12. The cutting device according to claim 1 , wherein the movable blade has a lower limit position and the adhesive removing element is at a fixed position that is below a cutting edge of the movable blade when the movable blade is at the lower limit position.

13. A label printer comprising:
a label roll holder;
a printing device configured to perform printing on a first side of a label portion supplied from a label roll mounted in the label roll holder; and
a cutting device configured to cut the label portion,
wherein the cutting device includes:
a fixed blade;
a movable blade configured to slide past the fixed blade; and
a cleaning tool with an adhesive removing element that comes into contact with a surface of the movable blade that faces the fixed blade.

14. The label printer according to claim 13 , wherein the movable blade is provided to face a second side of the label portion opposite to the first side.

15. The label printer according to claim 14 , wherein an adhesive is provided on the second side of the label portion.

16. The label printer according to claim 13 , wherein the fixed blade is provided upstream with respect to the movable blade in a label conveying direction.

17. The label printer according to claim 13 , wherein the cleaning tool includes a square-shaped rod with four longitudinal surfaces and the adhesive removing element is provided on at least a first one of the four longitudinal surfaces.

18. The label printer according to claim 17 , wherein the adhesive removing element includes a brush that extends outwardly from the at least one of the four longitudinal surfaces.

19. The label printer according to claim 18 , wherein the brush is arranged along a straight line.

20. The label printer according to claim 13 , wherein the movable blade has a lower limit position and the adhesive removing element is at a fixed position that is below a cutting edge of the movable blade when the movable blade is at the lower limit position.
