Abstract
(EN)
An imaging device is provided with: a moving lens frame (40) that holds a moving lens (41) on the inside and has magnets (60a - 60d and 70a - 70d) provided on an outside surface (40g) thereof; a holding frame (30) that holds the moving lens frame (40) on the inside freely movable in the optical axis direction (L) and has coils (21, 22) for generating drive force in the magnets (60a - 60d and 70a - 70d) provided in opposition with electrification on the outside surface (30g) thereof; and a magnetic member (50) that is provided facing the magnets (60c, 70c) in one direction (K1) more to the outside in the radial direction (K) than the outside surface (30g) of the holding frame (30) and generates an attractive force for the magnets (60c, 70c).
(FR)
L'invention concerne un dispositif d'imagerie, qui comprend : un cadre d'objectif mobile (40) qui maintient un objectif mobile (41) sur l'intérieur et possède des aimants (60a - 60d et 70a - 70d) situés sur sa surface extérieure (40g); un cadre de maintien (30) qui maintient le cadre d'objectif mobile (40) sur l'intérieur, librement mobile dans la direction d'axe optique (L), et possède des bobines (21, 22) pour générer une force d'entraînement dans les aimants (60a - 60d et 70a - 70d) situés en opposition avec l'électrification sur sa surface extérieure (30g); et un élément magnétique (50) qui est situé en face des aimants (60c, 70c) dans une direction (K1) plus à l'extérieur dans la direction radiale (K) que la surface extérieure (30g) du cadre de maintien (30), et génère une force d'attraction pour les aimants (60c, 70c).
