Transferred medium

Abstract

A transferred medium having a plate shape that can be nipped between a feed driving roller which is rotationally driven and a feed driven roller which is rotationally driven in contact with the feed driving roller, and being transferred in a secondary scan direction with the rotation of the feed driving roller, wherein a stress concentrated part, on which stress acting on the transferred medium when the transferred medium is nipped between the feed driving roller and the feed driven roller is concentrated, is integrally formed at a front end of the transferred medium with the transferred medium.

 wherein a projection part projected in the transferring direction is integrally formed at a front end of the transferred medium.    
   
   
       4 . The transferred medium according to  claim 3 , wherein the projection part has the shape of a tongue.  
   
   
       5 . The transferred medium according to  claim 3 , wherein the projection part is tapered toward the tip as seen in a longitudinal section of the transferred medium.  
   
   
       6 . The transferred medium according to  claim 5 , wherein the front end of the transferred medium is tapered toward the tip as seen in the longitudinal section of the transferred medium and a top surface thereof is not projected from a top surface of the projection part.  
   
   
       7 . The transferred medium according to  claim 3 , wherein a bottom surface of the projection part forms a flat plane along with a bottom surface of the transferred medium.  
   
   
       8 . The transferred medium according to  claim 3 , wherein the projection part is tapered toward the tip as seen in a plane view of the transferred medium.  
   
   
       9 . The transferred medium according to  claim 3 , wherein the transferred medium comprises a plurality of the projection parts at the front end thereof in a direction perpendicular to the transferring direction of the transferred medium with a predetermined pitch.  
   
   
       10 . The transferred medium according to  claim 3 , wherein the transferred medium is a tray having a setting part in which a thin plate member can be set.  
   
   
       11 . A transferred medium for carrying a target medium in combination with a transfer device for transferring the transferred medium in a transferring direction, wherein the transfer device comprises: a feed driving roller which is rotationally driven; and a feed driven roller which is rotationally driven in contact with the feed driving roller and wherein 
 the transferred medium has a plate shape and a projection part projected in the transferring direction, the projection part being integrally formed at a front end of the transferred medium with the transferred medium.    
   
   
       12 . The transferred medium according to  claim 11 , wherein the projection part has the shape of a tongue.  
   
   
       13 . The transferred medium according to  claim 11 , wherein the projection part is tapered toward the tip as seen in a longitudinal section of the transferred medium.  
   
   
       14 . The transferred medium according to  claim 13 , wherein the front end of the transferred medium is tapered toward the tip as seen in the longitudinal section of the transferred medium and a top surface thereof is not projected from a top surface of the projection part.  
   
   
       15 . The transferred medium according to  claim 11 , wherein a bottom surface of the projection part forms a flat plane along with a bottom surface of the transferred medium.  
   
   
       16 . The transferred medium according to  claim 11 , wherein the projection part is tapered toward the tip as seen in a plane view of the transferred medium.  
   
   
       17 . The transferred medium according to  claim 11 , wherein the transferred medium comprises a plurality of the projection parts at the front end thereof in a direction perpendicular to the transferring direction with a predetermined pitch.  
   
   
       18 . The transferred medium according to  claim 11 , wherein the feed driven roller of the transfer device is axially supported by a holder member which is biased such that the feed driven roller comes in close contact with the feed driving roller, and 
 wherein the projection part is formed to come in close contact with the feed driven roller at a position spaced far from a position where a biasing means for biasing the holder member applies a biasing force to the holder member.    
   
   
       19 . The transferred medium according to  claim 18 , wherein the transfer device comprises a plurality of the feed driven roller, the feed driven roller comprising: a first feed driven roller which come into contact with the projection part; and second feed driven roller which do not come into contact with the projection part and is kept in a free state.  
   
   
       20 . The transferred medium according to  claim 19 , wherein the second feed driven roller is disposed to come into contact with the front end of the transferred medium.  
   
   
       21 . The transferred medium according to  claim 11 , wherein the transfer device further comprises a guide member for guiding the transferred medium into a nipping portion between the feed driving roller and the feed driven roller.
