While 92 is in contact with the peeling roller 41 that applies tension to the peeling paper H and is rotationally connected to the peeling pinch roller 42 that is rotationally driven, as shown in FIG. The difference is that the 42 is rotationally connected via a one-way clutch 96.

In the label sending device of the fourth embodiment, the one-way clutch 96 allows the rollers 91 and 92 to be used.
Since the rotational direction of the label L is restricted to one direction, the curl of the label L can prevent the rollers 91 and 92 from being reversed, and the label L is inserted between the roller 91 and the label peeling guide 20. Therefore, it is possible to prevent the label L from being damaged by being jammed.
