Description

[0001] LINER LESS LABEL PRINTER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linerless label printer, and more particularly, to a linerless label printer that can maintain tension during movement of a linerless label paper to improve operation stability and print quality, To a linerless label printer that can be used interchangeably, regardless of the size of a rolled-up label sheet.

In general, label printers are widely used for printing prices, brands, and distribution periods of products.

A label printer performs a printing operation on a roll of label paper. The label paper includes a print paper and a liner-type label paper having a peelable liner attached to the back of the print paper, and a liner And a linerless label sheet composed of only prints.

A label printer using a linerless label paper is generally called a linerless label printer, and has a structure as disclosed in Korean Patent Registration No. 10-1739641, for example.

The printer according to the above-mentioned Japanese Patent No. 10-1739641 includes a discharge port 110, a first rotating member 120, a second rotating member 120, The paper 101 is fixed to the first and second rotary members 120 and 130 and is drawn out through the discharge port 110 while being pressed against the printing unit 210 As shown in FIG.

 1, unlike a label printer using a liner-bearing type label paper, the conventional linerless label printer is not provided with a spindle for rewinding the liner peeled off from the printing paper so as to take tension, There is no tension device of the present invention. As a result, the label paper 101 is drawn out through the discharge port 110 in a state in which no tension is applied to the label paper, which causes a malfunction in the printing process or a printing quality is deteriorated due to lack of stability of printing.

Since the conventional label printer can not use the label paper with the liner and the linerless label paper in an interchangeable manner, the label printer using the label paper with the liner and the linerless printer must be separately provided, and the label Since the standard and size of the printer are changed according to the size of the diameter of the paper, it is inconvenient to use and there is a limit to increase the cost of the consumer.
