Abstract

PURPOSE:To realize a smooth paper discharge and to improve an assembly workability by a method wherein mount paper is led out, printing is effected on a label, and the mount paper is peeled from the label by being bendignly led out by a label peeling body to be discharged from a paper discharge port. CONSTITUTION:With the input of a printing signal to a printing part 13, printing is effected on a label 16a on mount paper 16. When a platen 10 is driven, the mount paper 16 is led out from a mount paper containing part 21 and bent acute by a label peeling body 18. In this manner, the printed label 16a is peeled from the mount paper 16 and issued from a label issuance port 7. The part of the mount paper 16 from which the label 16a has been peeled is discharged out of a paper discharge port 6. Since the mount paper 16 is guided by a mount paper guide face 25, there is no possibility that the part of the mount paper 16 to be discharged may come into contact with a wound part thereof on the side of the mount paper containing part 21.
