Abstract
A winding shaft, for use in a printer, which allows a wound recording paper to be easily removed therefrom. The winding shaft includes a shaft main body, a winding portion and a support-removing member. The winding portion, which sandwiches the shaft main body, winds the recording paper therearound. The shaft main body includes a pair of support-removing members, which respectively project from the shaft main body. The two support-removing members are respectively supported on the two side portions of the shaft main body in such a manner that they can be freely rotated about their respective support shafts. A tension-coiled spring is bridgingly disposed between the two support-removing members, so that the two support-removing members remain in standing positions when no external force is applied to them. If the recording paper is lightly rotated in a direction opposite to the winding direction of the recording paper, then the two support-removing members are brought down in the same direction due to an external force applied thereto from the innermost peripheral recording paper. As a result, the innermost peripheral recording paper is loosened, that is, is caused to float loosely from the outer peripheral surface of the shaft main body, thereby enabling the removable of the recording paper from the winding shaft.
