As shown in No. 5, the label continuum with the label temporarily attached to the backing paper is mounted on the label supply shaft provided in the printer body, and is sequentially transferred from the label printing section to the label peeling section, and the printed label is peeled off. There is known a label printer which peels off at a part and feeds out to a label take-out port.

[0003] In a label printer having such a label peeling section, in order to facilitate the peelability of the label at the label peeling section and the transport of the label to the label take-out port, or the winding of the backing paper after the label peeling, the label printer is used. A label feeder comprising a feed roller and a pressure roller is provided downstream of the printing unit, and a mount is sandwiched between the feed roller and the pressure roller to be conveyed to a mount winding shaft.

[0004] In the case of a label printer equipped with such a label feeder, it is troublesome to deal with paper jams in the label continuity due to a printing operation or an operation of the label continuity, so-called jamming. That is, although a feed roller and a pressure roller are provided on the downstream side of the label peeling section, the pressure roller is fixed to the printer main body, and when the label continuous body jams in the label printing section or between the feed roller and the pressure roller, the pressure is increased. It was necessary to remove the roller, and the operation was troublesome.

Further, apart from jamming, when a label continuous body is mounted on a printer body, a band-shaped label continuous body is inserted between a feed roller and a pressure roller because of being fixed to the printer body. The work was unexpectedly cumbersome.
