Problems solved by technology

[0005] However, in the reverse feeding in which the linerless label is fed in the opposite direction to the print feed direction, the linerless label is moved from the position of the thermal head in a state of being slightly adhered to the outer periphery of the platen roller toward the print feed direction. The upstream side is conveyed and caught in the gap between the platen roller and the cover, as a result, there are cases where the linerless label sticks to the end of the cover and jams
In particular, this type of adhesive jam occurs when a linerless label is held between the thermal head and the platen roller for an extended period of time

Abstract

The inner cover (3b) installed on the back side of the open end of the opening and closing cover (3) for opening and closing the paper storage part (6) of the printer (1) is provided with a Protruding head (3c) with tapered thickness. In this protruding head (3c), when the label continuous body is fed, the first surface (S1) facing the adhesive layer is provided with a part of the outer circumference of the platen roller (10) facing the first surface (S1). The protruding portion (3e) protruding from the first surface (S1) is provided with a first rib (R1) on the surface of the protruding portion (3e). The first rib (R1) has a function of peeling the label continuous body from the outer periphery of the platen roller (10) during reverse paper feeding.

Description

technical field [0001] The present invention relates to a printer, for example, a label printer that prints desired information such as characters, symbols, graphics, or barcodes on a continuous label. Background technique [0002] The label printer is, for example, a printer for label printing in which the platen roller is rotated to convey the label while one end of the label continuous body wound in a roll shape is interposed between the thermal head and the platen roller. Continuum, at this time, print the desired information on the label. [0003] This label printer is described, for example, in Japanese Patent Application Laid-Open No. 2008-62597, which discloses that a platen roller is provided in a rotatable state at the open end of the opening and closing cover of the storage section of the continuous label continuous body. , and inside the label printer, a label printer with a thermal head is installed at the opposite position of the platen roller after the openin...
