         8 . The control device according to  claim 7 , wherein the radiography control unit performs control of prohibiting capture of the radiographic image in a case where the ultrasonography member is provided on the surface of the pressing member which is on the side opposite to the surface that comes into contact with the breast. 
     
     
         9 . The control device according to  claim 7 , wherein the radiography control unit performs control of warning against capture of the radiographic image in a case where the ultrasonography member is provided on the surface of the pressing member which is on the side opposite to the surface that comes into contact with the breast. 
     
     
         10 . The control device according to  claim 7 , wherein the radiography control unit performs control of prohibiting that the ultrasonography member is provided on the surface of the pressing member which is on the side opposite to the surface that comes into contact with the breast, before capture of the radiographic image. 
     
     
         11 . The control device according to  claim 7 , wherein the ultrasonography control unit performs control of prohibiting capture of the ultrasound image in a case where the ultrasonography member is not provided on the surface of the pressing member which is on the side opposite to the surface that comes into contact with the breast.
