Label printer
According to one embodiment, there is provided a label printer in which noise is less likely to be generated when a thermal head comes into contact with a backing sheet between a label and a label. In a label printer that prints, using a thermal head including a linear heating element, on a label sheet in which labels are attached on a strip-shaped backing sheet at a predetermined interval, the thermal head is configured to swing with respect to a platen roller configured to support the label sheet at a printing position, and a guide portion includes an edge portion that is substantially parallel to a surface of the thermal head having the heating element provided thereon and that is inclined with respect to the heating element is integrally provided downstream of the thermal head in a sheet conveying direction.
1. A label printer, comprising:
a thermal head including a linear heating element that prints on a label sheet in which labels are attached on a strip-shaped backing sheet at a predetermined interval, the thermal head configured to swing with respect to a platen roller configured to support the label sheet at a printing position; and
a guide including an edge portion substantially parallel to a surface of the thermal head having the linear heating element provided thereon and inclined with respect to the linear heating element integrally provided downstream of the thermal head in a sheet conveying direction, the guide having a surface on a downstream side in the sheet conveying direction inclined with respect to a width direction of the label sheet.
2. The label printer according to claim 1 , wherein
the edge portion of the guide has a length so that a part of the edge portion is in contact with an edge of a surface of a first label when the heating element of the thermal head moves from the surface of the first label due to conveying of the label sheet and comes into contact with the strip-shaped backing sheet between the first label and a second label adjacent thereto.
3. The label printer according to claim 1 , wherein
the guide is provided over an entire area of the thermal head in a width direction thereof.
4. The label printer according to claim 3 , wherein
the edge portion is present over the entire area of the thermal head in the width direction thereof.
5. The label printer according to claim 1 , wherein
the edge portion has a substantially linear shape.
6. The label printer according to claim 1 , wherein
a lower surface and an upper surface of the guide each have a substantially trapezoidal shape.
7. The label printer according to claim 1 , wherein
the lower surface of thermal head and the lower surface of the guide are substantially parallel.
8. A thermal printer configured to print labels, comprising:
a platen roller configured to support a label sheet comprising labels on a strip-shaped backing sheet at a printing position;
a thermal head including a linear heating element that prints on the label sheet, the thermal head configured to swing with respect to the platen roller; and
a guide including an edge portion substantially parallel to a surface of the thermal head having the linear heating element provided thereon and inclined with respect to the linear heating element integrally provided downstream of the thermal head in a sheet conveying direction, the guide having a surface on a downstream side in the sheet conveying direction inclined with respect to a width direction of the label sheet.
9. The thermal printer according to claim 8 , wherein
the edge portion of the guide has a length so that a part of the edge portion is in contact with an edge of a surface of a first label when the heating element of the thermal head moves from the surface of the first label due to conveying of the label sheet and comes into contact with the strip-shaped backing sheet between the first label and a second label adjacent thereto.
10. The thermal printer according to claim 8 , wherein
the guide is provided over an entire area of the thermal head in a width direction thereof.
11. The thermal printer according to claim 10 , wherein
the edge portion is present over the entire area of the thermal head in the width direction thereof.
12. The thermal printer according to claim 8 , wherein
the edge portion has a substantially linear shape.
13. The thermal printer according to claim 8 , wherein
a lower surface and an upper surface of the guide each have a substantially trapezoidal shape.
14. The thermal printer according to claim 8 , wherein
the lower surface of thermal head and the lower surface of the guide are substantially parallel.
15. A label printer, comprising:
a platen roller configured to support a label sheet comprising labels on a strip-shaped backing sheet;
a thermal head including a linear heating element that prints on the label sheet, the thermal head configured to swing with respect to the platen roller;
a guide including an edge portion substantially parallel to a surface of the thermal head having the linear heating element provided thereon and inclined with respect to the linear heating element integrally provided downstream of the thermal head in a sheet conveying direction, the guide having a surface on a downstream side in the sheet conveying direction inclined with respect to a width direction of the label sheet;
a cutter to cut the label sheet after printing; and
a discharge port through which a printed label is conveyed.
16. The label printer according to claim 15 , wherein
the edge portion of the guide has a length so that a part of the edge portion is in contact with an edge of a surface of a first label when the heating element of the thermal head moves from the surface of the first label due to conveying of the label sheet and comes into contact with the strip-shaped backing sheet between the first label and a second label adjacent thereto.
17. The label printer according to claim 15 , wherein
the guide is provided over an entire area of the thermal head in a width direction thereof.
18. The label printer according to claim 17 , wherein
the edge portion is present over the entire area of the thermal head in the width direction thereof.
19. The label printer according to claim 15 , wherein
the edge portion has a substantially linear shape.
20. The label printer according to claim 15 , wherein
a lower surface and an upper surface of the guide each have a substantially trapezoidal shape.
