Abstract

Provided is a medium conveying apparatus to be able to satisfactorily install a roller to assist conveyance of a medium to a loading tray. A medium conveying apparatus includes a loading tray including a placement surface provided with an opening, to place a medium, a roller to assist conveyance of the medium, and a holding part provided on the placement surface, to hold both ends of a rotation axis of the roller. The holding part includes a first arm and a second arm standing on a front side of the placement surface. At least one of the first arm and the second arm is provided to be bent outward in a direction perpendicular to a medium conveying direction when the roller is installed from a back side of the placement surface through the opening.

1 . A medium conveying apparatus comprising:
 a loading tray including a placement surface provided with an opening, to place a medium;   a roller to assist conveyance of the medium; and   a holding part provided on the placement surface to hold both ends of a rotation axis of the roller, wherein   the holding part includes a first arm and a second arm standing on a front side of the placement surface, and wherein   at least one of the first arm and the second arm is provided to be bent outward in a direction perpendicular to a medium conveying direction when the roller is installed from a back side of the placement surface through the opening.   
     
     
         2 . The medium conveying apparatus according to  claim 1 , wherein at least one of the first arm and the second arm is provided to be bent inward in a direction perpendicular to the medium conveying direction when the roller is pressed from the front side of the placement surface to the back side. 
     
     
         3 . The medium conveying apparatus according to  claim 1 , wherein the holding part is attachably and detachably provided on the placement surface. 
     
     
         4 . The medium conveying apparatus according to  claim 1 , wherein a diameter of the roller at an end in the direction perpendicular to the medium conveying direction is less than a of the placement surface diameter of the roller at a central part in the direction perpendicular to the medium conveying direction. 
     
     
         5 . The medium conveying apparatus according to  claim 1 , wherein
 a rotation axis of the roller is an aperture or a recessed part, and   an engaging part engaged with the aperture or the recessed part is formed on the holding part.   
     
     
         6 . The medium conveying apparatus according to  claim 1 , wherein
 the holding part includes an aperture or a recessed part, and   a rotation axis of the roller is an engaging part engaged with the aperture or the recessed part.
