Patent number: 11953820Abstract: An aperture unit includes a base plate, a cover, a plurality of aperture blades, a drive ring, and protrusions. The aperture blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of an opening. The drive ring is disposed between the base plate and the cover, and is rotationally driven when the aperture blades are opened and closed. The protrusions are provided to the drive ring and the cover, respectively, and support the aperture blades in the direction of suppressing upward warpage of the aperture blades in a state in which the aperture blades move in the direction of reducing the size of the opening.Type: GrantFiled: February 26, 2020Date of Patent: April 9, 2024Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Toshiyuki Nakada, Tetsuya Uno, Satoshi Fukuda

Publication number: 20060082947Abstract: In turn-on state, it is monitored whether a power switch 15 is pressed or not (ST1). When not pressed, it is continuously monitored whether pressed or not. When it is judged that the power switch 15 is pressed, it is monitored whether the power switch 15 is pressed continuously for no less than 2 seconds or not (ST2). When it is judged that the power switch 15 is not pressed continuously for no less than 2 seconds, back to ST1, it is continuously monitored whether the power switch 15 is pressed or not. When it is judged that the power switch 15 is pressed continuously for no less than 2 seconds, the process of turning off the power is started (ST3).Type: ApplicationFiled: October 19, 2005Publication date: April 20, 2006Inventors: Taiga Sato, Tetsuya Nakada
