Abstract

PROBLEM TO BE SOLVED: To prevent a mount from slacking on a site of a turning bar and allow a label piece to be surely peeled off from the mount of a contiguous label body by providing an upstream pressing member and a downstream press ing member on a part of the turning bar for peeling labels. SOLUTION: After printing is done by a printing means 4 on a contiguous label body 2 comprising label pieces 11 and a mount 10 supplied from a label supply means 3, when the mount 10 is turned at a part of a label peeler 21, an upstream roller pushes the contiguous label body 2 in a direction of an upper plane 14B of a turning bar 14 on an upstream of the turning bar 14 while a downstream roller 23 pushes the mount 10 in a direction of a lower slope 14C of the turning bar 14 in a downstream of the turning bar 14. Thus the contiguous label body 2 can turn around a tip 14A in an acute angle without slacking, whereby the label piece 11 can be reliably peeled off from the mount 10 and reliability of a label printer 20 and its peeler 21 can be improved.

In order to peel off the label piece 11 by turning 0, it is necessary to pull the backing sheet 10 in a downstream direction by the driving roller 16 and the driven roller 17 or the backing sheet winding means 6 with a predetermined tension. However, since the mount 10 itself has a predetermined rigidity, the label continuum 2
Alternatively, the mount 10 is turned by the turning bar 14 (the tip 14A,
There is a problem that the label pieces 11 may not be peeled off smoothly as a result of sagging as shown in FIG. 3 instead of turning exactly along the upper plane 14B and the lower inclined plane 14C). In addition, although some tension is applied to the backing sheet 10 on the downstream side of the turning bar 14 by the guide roller 15, it is not enough.

The problem of the slack in the turning bar 14 can be solved by pulling the mount 10 more strongly at the driving roller 16 and the driven roller 17. And platen roller 13
However, there is a problem that the label continuous body 2 and the carbon ribbon 7 are shifted, and the printing itself is shifted in the transport direction of the label continuous body 2. It is also conceivable to make the tip 14A of the turning bar 14 an acute angle. However, there is a limit from the viewpoint of safety as a product, and it is difficult to completely prevent the mount 10 from sagging.
