Rolled medium holder device and recording apparatus

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....

AI Technical Summary

Benefits of technology

[0009]It is an advantage of some aspects of the invention to provide a rolled medium holder device that takes into consideration breakages in a guide portion when a holder portion that is slidable relative to the guide portion is immobilized relative to the guide portion, and to provide a recording apparatus that includes the rolled medium holder device.

[0010]A rolled medium holder device according to a first aspect of the invention includes: a guide member that extends in the width direction of a rolled medium; a holder unit, including a shaft portion that holds the 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 position of the holder unit can be immobilized relative to the guide member by increasing the pressing force; and the holder unit can be slid relative to the guide member by reducing the pressing force from the immobilized state.

[0011]According to this aspect, the stopper member makes surface contact with the outer circumferential surface of the guide member, and thus there is no risk of the stopper member scratching the outer circumferential surface of the guide member. In addition, the pressing force is not concentrated at a single point, and there is therefore no risk of the guide member being damaged. The holder unit can be immobilized relative to the guide member without damage particularly in the case where the guide member is hollow and thin in order to reduce the weight thereof.

Problems solved by technology

If such is the case, there is a risk that the area of the guide portions where the tips of the screws make contact will be scratched, deformed, or the like.

In addition to having the same effects as the first aspect, according to this aspect, there is a risk of the guide member being damaged in the case where the guide member is hollow.
