Embodiment Construction

[0033]Hereinafter, embodiments of the invention will be described with reference to the drawings.

[0034]FIG. 1 is a cross-sectional view, seen from the side, illustrating an outline of the overall configuration of a large-format ink jet printer 1 (called simply a “printer” hereinafter), serving as a recording apparatus according to this embodiment.

[0035]As shown in FIG. 1, the printer 1 includes a medium feed-out mechanism 26, a recording unit 28, and a take-up mechanism 37. Of these, the medium feed-out mechanism 26 is configured so as to be capable of releasing a rolled medium R, which is wound up in roll form, and feeding that rolled medium R in a feed direction Q. Specifically, the medium feed-out mechanism 26 includes first holder units 3 and a roller pair 29.

[0036]Of these, the first holder units 3 are provided so as to be capable of holding both ends of the rolled medium R so that the rolled medium R can rotate. Each of the first holder units 3 includes a shaft portion 13 that...

Abstract

A rolled medium holder device includes: a guide member; a holder unit, including a shaft portion that holds a roll-shaped rolled medium, that is slidable relative to the guide member; and a stopper member, provided in the holder unit, that makes surface contact with the outer circumferential surface of the guide member. Here, the pressing force exerted on the outer circumferential surface of the guide member by the stopper member between two different points of the stopper member in the circumferential direction of the guide member can be adjusted; the holder unit is immobilized by increasing the pressing force; and the holder unit can be slid by reducing the pressing force.

Description

[0001]This application claims priority to Japanese Patent Application No. 2011-021853, filed Feb. 3, 2011 which is expressly incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to rolled medium holder devices that hold roll-shaped media and recording apparatuses provided with such rolled medium holder devices.[0004]The “recording apparatus” referred to in this application is assumed to include various types, such as ink jet printers, wire dot printers, laser printers, line printers, copiers, facsimile machines, and so on.[0005]2. Related Art[0006]Thus far, some recording apparatuses have included holder devices that hold roll-shaped rolled paper, such as that disclosed in JP-A-2009-234668. This holder device includes a pair of holders provided on both sides of the rolled paper. At least one of the holders in the pair is provided so as to be capable of sliding along guide portions extending in the width direction of the rolled paper....
