Abstract

A feed mechanism includes: a feed tray accommodating a roll body, a first sheet-shaped medium being rolled in a roll shape as the roll body, the feed tray including: a first accommodation portion accommodating the roll body; a pair of side walls respectively provided on both sides of the first accommodation portion in an axial direction of the roll body that is accommodated in the first accommodation portion; and a side guide disposed inside the pair of side walls.

What is claimed is: 
     
         1 . A feed tray configured to be detachably inserted to a housing of an image forming apparatus, the feed tray comprising:
 a first accommodation portion configured to accommodate a roll body in which a sheet-shaped medium is rolled;   a bottom wall that defines a bottom surface of an introduction path for guiding the sheet-shaped medium unrolled from the roll body in a guiding direction, the bottom wall extending in the guiding direction;   a member that defines an upper surface of the introduction path, the member extending in the guiding direction; and   a side guide configured to be movable to be contactable with the sheet-shaped medium located within the introduction path.   
     
     
         2 . The feed tray according to  claim 1 , wherein the side guide is contactable with:
 at least one end of the roll body accommodated in the first accommodation portion in an axial direction of the roll body; or   at least one end of the sheet-shaped medium unrolled from the roll body in the axial direction.   
     
     
         3 . The feed tray according to  claim 1  further comprising:
 a first side wall; and 
 a second side wall. 
 
     
     
         4 . The feed tray according to  claim 3 ,
 wherein the first side wall and the second side wall are arranged to face each other and configured to extend in the guiding direction.   
     
     
         5 . The feed tray according to  claim 4 ,
 wherein the side guide is located at a position between the first side wall and the second side wall, and   wherein the side guide is configured to be movable in a direction from the first side wall towards the second side wall to be contactable with the sheet-shaped medium located within the introduction path.   
     
     
         6 . The feed tray according to  claim 3 ,
 wherein the side guide is movable in an axial direction of the roll body independently from movement of the first side wall and the second side wall.
