Publication number: 20140193145Abstract: An accessory side mount of the camera accessory includes at least a first limiting portion and a second limiting portion that is different from the first limiting portion. When the first through third claws are rotated in a first rotational direction along the circumferential direction in order to install the accessory side mount that has been inserted in the proper installation and detachment rotational phase into the body side mount, the first limiting portion limits a range of rotation in the first rotational direction by abutting an end surface of one of the camera body side claws. When the first through third claws are rotated in a second rotational direction along the circumferential direction that is opposite to the first rotational direction in order to detach the accessory side mount from the body side mount, the second limiting portion limits a range of rotation in the second rotational direction by abutting an end surface of one of the camera body side claws.Type: ApplicationFiled: March 11, 2014Publication date: July 10, 2014Applicant: NIKON CORPORATIONInventors: Masanori HASUDA, Hideaki HOSHIKAWA, Noriyasu KOTANI
