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.

1 . A rolled medium holder device comprising:
 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,   wherein a 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.   
     
     
         2 . The rolled medium holder device according to  claim 1 , wherein the guide member is hollow. 
     
     
         3 . The rolled medium holder device according to  claim 1 , wherein the magnitude of the pressing force is changed by changing the position of at least one of the two points in the stopper member. 
     
     
         4 . The rolled medium holder device according to  claim 1 , wherein the stopper member is formed of a flexible material. 
     
     
         5 . The rolled medium holder device according to  claim 1 , wherein the guide member and the holder unit make contact at at least two points in the circumferential direction, and the pressing force is exerted toward the area between the two points. 
     
     
         6 . The rolled medium holder device according to  claim 1 , wherein the stopper member is formed in a ring shape. 
     
     
         7 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 1 .   
     
     
         8 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 2 .   
     
     
         9 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 3 .   
     
     
         10 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 4 .   
     
     
         11 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 5 .   
     
     
         12 . A recording apparatus comprising:
 a feed-out mechanism capable of feeding out a roll-shaped rolled medium downstream in a feed direction;   a recording unit that records onto the fed-out rolled medium; and   a take-up mechanism that takes up the rolled medium that has been recorded onto,   wherein at least one of the feed-out mechanism and the take-up mechanism includes the rolled medium holder device according to  claim 6 .
