         5 . The opening/closing member holding device according to  claim 4 , wherein
 the body part includes a second opening, and   when one of the first engaging portion and the second engaging portion of the holding member enters the portion between the flange portion and the body part, the other of the first engaging portion and the second engaging portion is allowed to enter the second opening.   
     
     
         6 . The opening/closing member holding device according to  claim 2 , wherein both ends of the wire-shaped member making up the holding member are bent. 
     
     
         7 . The opening/closing member holding device according to  claim 3 , further comprising an arm configured to hold the opening/closing member when the opening/closing member is in the first open state, wherein
 the holding member does not hold the opening/closing member when the opening/closing member is in the first open state.   
     
     
         8 . A medium conveyance device comprising:
 a device body including a medium conveyance path configured to convey a medium, and   the opening/closing member holding device according to  claim 2 , wherein   the body part is provided at a side surface of the device body and configured to open and close such that the body part forms a part of the medium conveyance path when the body part closes and forms a part of the medium conveyance path when the body part opens, and   the opening/closing member is a support tray configured to support the medium that is supplied.   
     
     
         9 . A medium conveyance device comprising:
 a device body including a medium conveyance path configured to convey a medium, and   the opening/closing member holding device according to  claim 3 , wherein   the body part is provided at a side surface of the device body and configured to open and close,   the opening/closing member is a support tray configured to support the medium that is supplied,   the device body includes a medium storage unit configured to store the medium,   when a side surface where the medium storage unit is provided in the device body is set to a front surface of the device body, the body part is provided at a right side surface or a left side surface of the device body, and   the holding member restricts a movement of the cover in the detaching direction of the cover on a device front surface side of the cover with the body part in the closed state.   
     
     
         10 . The medium conveyance device according to  claim 8 , further comprising:
 a supplying roller configured to supply the medium from the support tray; and   a rotation shaft of the supplying roller, wherein   the second engaging portion is engageable with the rotation shaft of the supplying roller.   
     
     
         11 . The medium conveyance device according to  claim 10 , wherein
 a groove is formed in the rotation shaft of the supplying roller,   a hook that is engageable with the groove is provided at the supplying roller, and   the second engaging portion is engageable with the groove.   
     
     
         12 . The medium conveyance device according to  claim 8 , wherein
 a plurality of medium detection units configured to detect the medium are provided in the conveyance path of the medium, and   the plurality of the medium detection units are accessible when the cover is detached from the body part.
