<P>PROBLEM TO BE SOLVED: To improve a feeling at the time of switching by slide movement of ring members that rotate relative to a lens barrel body and slidably move in an optical axis direction. <P>SOLUTION: When a first focus ring 20, that is arranged to be capable of endlessly rotating relative to a lens barrel body 10 and is slidably arranged between a first slide position and a second slide position in an optical axis direction, is moved to the first slide position or the second slide position, the first focus ring 20 is biased in a slide direction by repulsion between an electromagnet 14 and a permanent magnet 26 once passing over an intermediate position of the slide position, and is moved to a movement end connecting with a second focus ring 30 or a third focus ring 40. Further, the electromagnet 14 has magnet force which is adjustable, thereby arbitrarily adjusting an operation feeling at the time of switching of the first focus ring 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
