Patent number: 9480134Abstract: An image pickup apparatus includes a metal body, a metallic lens barrel provided movably in an optical axis direction of an imaging optical system, and a metallic exterior casing having an opening that exposes the lens barrel from inside to outside the image pickup apparatus. The metal body includes a cut-and-raised portion formed by cutting and raising a part of the metal body, and the cut-and-raised portion is electrically connected with the exterior casing or inductively coupled with the exterior casing. The cut-and-raised portion is formed to electrically discharge the lens barrel charged with static electricity via a discharge path including the cut-and-raised portion. A static electrical current generated in the lens barrel flows to ground via the discharge path including the exterior casing, the cut-and-raised portion and the metal body, without flowing via any electric substrate, to discharge a charged lens barrel.Type: GrantFiled: December 16, 2013Date of Patent: October 25, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Masafumi Kumoi, Masato Tobinaga
