Therefore, by rotating the opening / closing cover 20 downward and closing it on the main body base 19, the label 10 and the sheet 11 project from the label issuing port 42 and the sheet discharge port 35, respectively, as illustrated in FIG. 7. The label sheet 5 is set in this state.

In the label printer 17, three roller units 47, which prevent the label 10 protruding forward by the support of the label supporting roller 49 from curving, are connected in the width direction of the label sheet 5. Holder hole 31
Each of the two roller units 47 can be detachably attached to the slide frame 23.
The wide label 10 can be satisfactorily supported by being attached to each of the holder holes 31 on both sides of the label. By mounting one roller unit 47 in the holder hole 31 in the center of the slide frame 23, the narrow label 10 can be favorably supported. In this case, unnecessary labels are provided on both sides of the narrow label 10. Since the support roller 49 is not located,
It is possible to prevent the finger for picking up the label 10 from colliding with the label support roller 49 and improve workability. Moreover, in the label printer 17, the label supporting roller 49 mounted on the slide frame 23 slides forward together with the pinch roller 14, so that the label supporting roller 49 impairs workability when setting the label sheet 5. Nor.

In this embodiment, as the label peeling device, the label printer 17 which prints an image on the label 10 of the label sheet 5 has been exemplified, but the present invention is not limited to the above-mentioned form, and the label 10 is preliminarily imaged. It is also applicable to a label sticking device (not shown) that uses the label sheet 5 on which is printed.
