Sheet feeder

Abstract

A sheet feeder superior in performance of sheet conveyance, suitable for downsizing, and improved in usability. The sheet feeder comprises a roll holder having a roll mounting section and a cover member attached to the roll holder. The cover member is rotatable around the roll mounting section and automatically conveys a sheet with a pullout portion of the sheet of a roll put between a receiving section formed in the lower portion of the cover member and a feeding roller.

1 . A sheet feeder comprising: 
 a roll mounting section for receiving a roll of a continuous sheet wrapped around itself; and    a conveying mechanism for automatically paying out the sheet of the roll mounted on the roll mounting section, wherein:    a receiving section is provided on one side of a pullout portion of the sheet of the roll; and    the conveying mechanism includes a feeding roller holding the pullout portion put between the feeding roller and the receiving section on the other side of the pullout portion and a drive motor for rotatably driving the feeding roller to pull out and convey the sheet of the roll.    
   
   
       2 . The sheet feeder according to  claim 1 , further comprising a roll holder having the roll mounting section, wherein: 
 the feeding roller is placed on the side of the roll holder and located on the underside of the pullout portion; and    the receiving section is movable in a direction of approaching or moving away from the feeding roller on the upside of the pullout portion and biased in the direction of approaching the feeding roller.    
   
   
       3 . The sheet feeder according to  claim 2 , wherein the receiving section is formed in a rotating member supported by the roll holder so as to be rotatable around the roll mounted on the roll mounting section above the roll.  
   
   
       4 . The sheet feeder according to  claim 3 , wherein: 
 the rotating member is rotatable forward or backward of the roll mounting section under its own weight from a neutral position above the roll mounting section; and    the receiving section is biased in the direction of approaching the feeding roller under the self weight of the rotating member.    
   
   
       5 . The sheet feeder according to  claim 4 , wherein the rotating member is provided with a weight for biasing the receiving section in the direction of approaching the feeding roller.  
   
   
       6 . The sheet feeder according to  claim 4 , wherein a metal faceplate is attached to the face of the rotating member.  
   
   
       7 . The sheet feeder according to  claim 3 , further comprising a stopper mechanism between the roll holder and the rotating member, the stopper mechanism limiting an amount of displacement of the receiving section toward the feeding roller to within a specified range of displacement.  
   
   
       8 . The sheet feeder according to  claim 3 , wherein the rotating member is a cover member rotatable between a position where the roll is covered and a position where the roll mounting section is open in the surrounding area.  
   
   
       9 . The sheet feeder according to  claim 2 , wherein the roll holder has a cutter in a downstream position of the feeding roller and the color of the cutter is different from the color of the roll holder.  
   
   
       10 . The sheet feeder according to  claim 1 , wherein the roll is rotatably mounted on the roll mounting section.  
   
   
       11 . The sheet feeder according to  claim 1 , wherein the feeding roller is disposed in a plurality of locations in the width direction of the pullout portion.  
   
   
       12 . The sheet feeder according to- claim 11 , wherein the sheet is toilet paper, kitchen paper, paper towel, wet tissue, paper for cleaning buttocks, paper for wiping grease, or aluminum foil.
