Abstract
(EN)
In a mechanism using a cam ring, the wobble between the gears sometimes affects the driving of the lens. Provided in the present invention is a lens device. The lens device can be provided with a cam ring that rotates in a first rotational direction and a second rotational direction opposite to the first rotational direction, so that the leans moves along an optical axis. The lens device can be provided with a drive source that generates power for rotating the cam ring. The lens device may comprise a gear portion having a first gear and a second gear coupled to each other to transmit power from the drive source to the cam ring. The lens device may have a force application portion that apply a force on the cam ring in the first rotation direction, so that a first tooth flank of the first gear and a second tooth flank of the second gear opposite the first tooth flank are in contact regardless whether the cam ring rotates in the first rotation direction or the second rotation direction.

L'oscillation entre les engrenages affecte parfois l'excitation de la lentille dans un mécanisme utilisant un anneau de came. La présente invention concerne un dispositif de lentille. Le dispositif de lentille peut être pourvu d'un anneau de came qui tourne dans une première direction de rotation et une seconde direction de rotation opposée à la première direction de rotation, de telle sorte que la lentille se déplace le long d'un axe optique. Le dispositif de lentille peut être pourvu d'une source d'excitation qui génère de l'énergie pour faire tourner l'anneau de came. Le dispositif de lentille peut comprendre une partie d'engrenage comportant un premier engrenage et un second engrenage accouplés l'un à l'autre pour transmettre de l'énergie de la source d'excitation à l'anneau de came. Le dispositif de lentille peut avoir une partie d'application de force qui applique une force sur l'anneau de came dans la première direction de rotation, de sorte qu'un premier flanc de dent du premier engrenage et un second flanc de dent du second engrenage opposé au premier flanc de dent soient en contact indépendamment du fait que l'anneau de came tourne dans la première direction de rotation ou dans la seconde direction de rotation.
