Embodiment Construction

[0040] Embodiments are described with reference to the drawings. figure 1 It is a vertical right side view schematically showing the structure of the printer 1 . The front of printer 1 is figure 1 in the left side. The printer 1 has a holding unit 3 , a damper 4 , and a printing unit 5 inside a housing 2 , and a paper discharge port 6 is provided on the front of the housing 2 .

[0041] The housing 2 has a box-shaped main body 21 with an open top, and a cover 22 for opening and closing the opening.

[0042] The holding unit 3 has a support shaft 31 and rotatably holds the linerless label roll via the support shaft 31 . The linerless label roll is a paper roll R in which a label L provided with an adhesive layer (not shown) on the back (back) of a tape-shaped paper is wound without a liner.

[0043] The damper 4 is provided between the label L pulled out from the paper roll R and the printing section 5 , and has a pressing roller 41 and a bias support section 42 . The pres...

Abstract

The invention discloses a paper supply device, a striping auxiliary device and a printer which can enable printing precision, while printing is started, to be improved. The paper supply device comprises a holding part, a roller and a roller support part; the holding part holds roll paper, which is winded with a label in a no-lining paper manner, through a support shaft in a freely rotating manner, the label is provided with an adhesive layer on the back face of belt-shaped paper; the roller rotates freely, and the roller is located on a downstream side in a paper conveying direction compared with the holding part and contacts the adhesive layer of the label pulled from the roll paper; the roller support part supports the roller in a tilt manner that heights of two ends of the roller are different while non-paper conveying, and accepts a tension force of the label pulled from the roll paper while paper conveying so that heights of the two ends of the roller are consistent.

Description

[0001] This application claims priority to the Japanese application with the filing date of January 22, 2014 and application number JP2014-009559, and cites the contents of the above application. technical field [0002] The invention relates to a paper feeding device, a peeling auxiliary device and a printer. Background technique [0003] Conventionally, there is a printer that prints on a paper roll wound with a linerless label having an adhesive layer provided on the back of a strip of paper, that is, a linerless label roll. In such printers, the labels are peeled off the label roll when the paper feed is initiated to pull the labels. [0004] When a label roller is used, compared with a label roller with a liner or a bill without an adhesive layer, the tensile force required for paper conveyance is large. Especially when starting paper feeding, that is, starting to peel off a label, a greater force is required than during paper feeding. [0005] The change in the force...
