Abstract
In a printer that performs printing on a label of a continuous paper while feeding the continuous paper unwound from a paper sheet supply unit, a platen roller portion is configured to be attachable and detachable only by operating an operating lever portion of an attaching and detaching operation portion. The attaching and detaching operation portion has its shaft fixed in a rotatable state between a bearing ring and a platen main body on one side in an axial direction of the platen roller portion. Pulling the operating lever portion of the attaching and detaching operation portion releases a locked state of the attaching and detaching operation portion itself and a locked state in the axial direction of the platen roller portion.
